Brutus and Antony#8217;s speeches to critical art lessons, the crowd after Caesar#8217;s death Essay Sample. #8220;Julius Caesar#8221; is top essay, a historical play by William Shakespeare. It is set in Italy, during the Roman era. The plot revolves around the critical art lessons murder of Julius Caesar and the power struggle between Caesar#8217;s friends and enemies. On E Cash? In this essay I will compare and contrast Brutus and Antony#8217;s speeches after Caesar#8217;s death. Critical Thinking? Both Brutus and Antony#8217;s speeches are used to try and convert the Roman public to their side.

After Brutus and his fellow conspirators kill Caesar outside the senate, Antony meets with Brutus and manages to persuade him that he agrees with the reasons why they killed the dictator, so that he is allowed to talk at Caesar#8217;s funeral. However, his real intentions are revealed in an emotional soliloquy that reveals that he is desperate to avenge his close friend Caesar. Brutus sets one condition on Antony#8217;s speech- that he must not say anything against the murderers. Brutus uses his speech to convince that he has acted for the common good of research paper on e cash payment system Rome, whereas Antony tries to make the people avenge the death of thinking art lessons his beloved Caesar. The first speech is that of Brutus. The most striking factor is the shortness of the hydrothermal vents chemosynthesis speech, but it is effective. It would be far less effective though, if the crowd didn#8217;t have such a high opinion of him. Critical? This is essay, demonstrated with the quote. #8220;Believe me for mine honour, and thinking art lessons, have respect to mine honour#8221;

The speech uses informal prose, which allows the audience to relate to him. He flatters the audience watching the writing services speech- describing them as having great wisdom. This flattery results in critical thinking the audience having confidence in him that helps him greatly later on in the speech. Also, he anticipates questions and provides answers to programs in new, them. Brutus is very democratic in his explanation of why they killed Caesar- he says he loved Caesar, but loved Rome more.

He claims that Caesar#8217;s downfall was due to critical art lessons, his high ambition, but isn#8217;t entirely effective. Again, he uses the crowd#8217;s high opinion of him to pull himself through this section of the speech. Towards the end of the speech he asks the crowd for a reply- this is a major gamble as it would be unlikely that he would be able to provide a satisfactory answer. Brutus#8217;s final comment is: #8220;As I slew my best lover for the/ good of Rome, I have the same dagger for myself/ when it shall please my country to need my death#8221; He obviously doesn#8217;t mean it, but it is a fine example of dramatic irony, as later on in the play Brutus kills himself with the same dagger after his army are defeated at bulls edgeworth, Philippi. In a manner similar to the opening scene- where the fickle crowd changes from art lessons, Pompey to Caesar- the public proclaim Brutus as their ruler. On the other hand, Antony#8217;s speech is far more clever and manipulative. From the offset Antony claims that Brutus is a superior speaker, and paper on e payment system, this is thinking, portrayed well when he says. Writing? #8220;I am no orator, as Brutus is#8221; He is far from being a poor orator- he speaks articulately and uses elegant blank verse. Critical Thinking Art Lessons? At the beginning he appears to uphold what the conspirators have done but then he picks out the flaws in Brutus#8217;s argument. He counteracts what Brutus says about Caesar#8217;s ambition by reaction rates, reminding the crowd of how the dictator: rejected the crown 3 times, brought money into critical thinking, the Roman coffers, was a faithful friend and was kind to the poor. Antony uses irony extensively as he refers to the assassins as #8216;honourable men#8217;.

The crowd is hydrothermal, won over thanks to the suggestions that Antony, which are used in place of open judgements. Thinking? Personal support is enlisted from he crowd, emphasized with the cry from a member of the audience: #8220;Poor soul! His eyes are red as fire with weeping#8221; The idea of mutiny and rage is planted into the minds of the crowd by Antony, even though he claims he is doing the opposite. The crowd is hydrothermal, tantalized by Antony as he lets them know about Caesar#8217;s will but says he refuses to read it out- even although his intention is to tell them. Antony sends the crowd into an even deeper frenzy when he gives an imaginative account of what happened during the murder, even though he wasn#8217;t present when it happened. He claims to know which wound was made by each of the conspirators, emphasizing the thinking art lessons cut supposedly made by Brutus as: #8220;The unkindest cut of mfa creative writing programs york all#8221; Finally Antony#8217;s objective is complete when he reads out the will, which causes rioting from his Audience.

Yet again the public have switched allegiances from different sides. Antony knows Caesar#8217;s revenge will be attained when he states: #8221; Now let it work mischief, thou art afoot/ Take thou what causes thou wilt#8221; Despite the fact that both speeches have very different reasons, they share quite a few similarities. Both speakers were very close friends of Caesar, which allows both to speak of what Caesar was really like accurately. The two speeches are used to win over the crowd to their point of view, despite the very different manifestoes. Critical Thinking Art Lessons? The opening of both speeches is similar- an reaction rates appeal for thinking art lessons attention from the confused crowd. The differences are far more striking: democratic Brutus believes he has acted for the common good whereas Antony wishes to avenge his beloved Dictator and increase his political career. The speeches of Brutus and Antony are key moments in Roman history and their quality is apparent for essay on irish such an important occasion.

Antony claims he is a poor orator, but gives an art lessons excellent talk which dismisses everything Brutus said. Due to this he secures revenge for Caesar and seals the fate of Rome.

Lorsqu'il lui offre ce portrait , Virginie, émue lui fait cette promesse : Mon frère, il ne me sera jamais enlevé tant que je vivrai et je n'oublierai jamais que tu m'as donné la seule chose que tu possèdes au monde. Critical Art Lessons! À ce ton d'amitié, à ce retour inespéré de familiarité et de tendresse, Paul voulut l'embrasser ; mais aussi légère qu'un oiseau elle lui échappa, et le laissa hors de lui, ne concevant rien à une conduite si extraordinaire. C'est alors qu'un nouveau danger apparaît ; la tante de la Mme de la Tour écrit à sa nièce lui enjoignant de lui envoyer Virginie, à laquelle elle destinait une bonne éducation, un parti à la cour, et la donation de tous ses biens . Au fond d'elle-même Mme de la Tour n'est pas mécontente de cette opportunité. Rates! Elle prend sa fille à part et tente de la raisonner Mon enfant, nos domestiques sont vieux ; Paul est bien jeune, Marguerite vient sur l'âge ; je suis déjà infirme : si j'allais mourir, que deviendriez-vous sans fortune au milieu de ces déserts ? vous resteriez donc seule, n'ayant personne qui puisse vous être d'un grand secours, et obligée, pour vivre, de travailler sans cesse à la terre comme une mercenaire.

Il voulut ensuite s'instruire dans la géographie pour se faire une idée du pays où elle débarquerait ; et dans l'histoire, pour connaître les mœurs de la société où elle allait vivre . Virginie est elle aussi désespérée d'abandonner Paul. Thinking! Loin de se réjouir de cette fortune que sa tante désire lui léguer, elle souffre de cette vie européenne à laquelle elle ne parvient pas à s'adapter. Hydrothermal Chemosynthesis! Pendant plus d'un an critical thinking Paul et Virginie restent sans nouvelles l'un de l'autre, les lettres qu'ils s'échangent , étant interceptées par la grand-tante de Virginie. York! Pendant cette année qui lui parait interminable , Paul qui lit maintenant des romans reste inconsolable : il fut tout bouleversé par la lecture de nos romans à la mode, pleins de mœurs et de maximes licencieuses ; et quand il sut que ces romans renfermaient une peinture véritable des sociétés de l'Europe, il craignit, non sans quelque apparence de raison, que Virginie ne dut à s'y corrompre et à l'oublier. Virginie, par des moyens détournés parvient enfin à faire parvenir à sa mère une première lettre. Thinking! Mme de la Tour découvre combien sa fille est malheureuse en métropole. On Irish Edgeworth! La richesse qui l'entoure, le titre de comtesse, les robes somptueuses, les deux femmes de chambre à ses soins ne parviennent pas atténuer la douleur de la séparation. Et quand la grand-tante se met en tête de marier Virginie, celle-ci préfère être déshéritée et chassée de France. Thinking! Elle ne pense plus dès lors qu'à Paul et au retour.

On annonce son retour imminent. On Mother Sacrifice! Sur le chemin du retour, au moment d'aborder son ïle natale, le Saint-Géran est pris dans la tempête. Thinking! Le bateau qui la ramène à l'île de France fait maufrage sous les yeux de Paul. Bulls Edgeworth!

Art Lessons! C'était Virginie. Essay On Irish Bulls Edgeworth! Elle avait reconnu son amant à son intrépidité. Art Lessons! La vue de cette aimable personne, exposée à un si terrible danger, nous remplit de douleur et de désespoir pour Virginie, d'un port noble et assuré, elle nous faisait signe de la main, comme nous disant un éternel adieu.

On entendit aussitôt ces cris redoublés des spectateurs : Sauvez la, sauvez la ; ne la quittez pas ! Mais dans ce moment une montagne d'eau d'une effroyable grandeur s'engouffra entre l'île d'Ambre et la côte, et s'avança en rugissant vers le vaisseau, qu'elle menaçait de ses flancs noirs et de ses sommets écumants. Coursework! À cette terrible vue le matelot s'élança seul à la mer ; et Virginie, voyant la mort inévitable, posa une main sur ses habits, l'autre sur son coeur et levant en haut des yeux sereins, parut un ange qui prend son vol vers les cieux.

On la voyait tout à coup gaie sans joie, et triste sans chagrin. Critical Thinking! On ne fait son bonheur, disait-elle, qu'en s'occupant de celui des autres.

Free Environmental Studies essays. Renewable energy is now capturing a good share of the worldwide headlines because of concerns about declining supplies of critical thinking fossil fuels, escalating population and industrialization triggering ever-increasing demand of writing fuels. Worldwide ethanol demand is increasing continuously. Conventional crops such as corn and sugarcane are unable to meet the global demand of bioethanol production due to their primary value of food and feed. Therefore, lignocellulosic substances such as agricultural wastes are attractive feedstocks for bioethanol production and they are too cost effective, renewable and abundant. Bioethanol from this agricultural waste could be a promising technology, though the process has several challenges and limitations such as biomass transport and handling, and ef’cient pretreatment methods for total deligni’cation of lignocellulosics. In this review are discussed efficient and available technologies for bioethanol production from agricultural waste. Keywords: Bioethanol, Pretreatment, Bioethanol production, Biomass, Lignocellulosic biomass, Agricultural waste.

Fossil energy sources such as oil, coal, natural gas, etc are important factors for the world’s present economy development, they make everything work from fuel to electricity and other goods. (Uihlein A. et al., 2009). The last few decades brought with them excessive consumption of art lessons fossil fuels, especially in large urban areas, and a high level of pollution. (Ballesteros I et al., 2006). The global production of oil is decreasing significantly from year to year and mfa creative writing in new york that’s due to the expansion of human population and increasing of industrial property, which is also generating a high energy consumption. (Campbell CH, Laherrere JH, 1998). Renewable sources , as wind, water, sun, biomass, geothermal heat might be the future, the alternative needed for the energy industry wheres the fuel production and the chemical industry may have as an alternative for the near future the biomass (Lynd LR, Wang MQ, 2003). Thinking Art Lessons! The renewable biomass fuels such as bioethanol, biodiesel, biohydrogen, etc., derived from sugarcane, corn, switchgrass, algae, etc. Essay! can become the perfect substitutes for all petroleum-based fuels.

Each person’s share of electricity and fuel used in making food and goods and their transport represint the energy consumption rate. A possible motor fuel on organic farms in the short and medium terms is represented by biogas. This alternative fuel can be produced by thinking, anaerobic digestion of organic material. When it is used as biofuel, the CO2 present in it is removed for essay on mother sacrifice increasing the energy content and it can be stored at high pressure. Biogas can be a substitute as fuel for boilers, propane and natural gas and in rural areas for electricity generation. Biogas energy usage expansion has continued across the critical, European Union. According to Eur Observ’ER, about 13. 4 million tonnes oil equivalent (Mtoe) of biogas primary energy were produced during 2013, which is reaction rates 1.2 Mtoe more than in 2012 representing a 10.2% growth. However, the biogas sector’s momentum was more sluggish than in 2012 (16.9% between 2011 and 2012, giving an additional 1.8 Mtoe) and it is expected to lose some of its impetus in 2014 in thinking a number of countries whose sector expansion controlling policy changes will limit the on e payment system, future use of energy crops. 52.3 TWh (TeraWatt hour) of biogas electricity produced in 2013 in the European Union. The growth of biofuels consumption for use in transport in the European Union (EU-28) has dwindled in the past few years and finally dropped by critical, about 1 million toe (6.8%) between 2012 and 2013 according to EurObserv’ER, to a consumption level of 13.6 million toe.

Nevertheless, sustainable biofuel consumption, certified and thus eligible for inclusion in European targets increased slightly by on irish bulls edgeworth, 1.1% to 11.8 Mtoe (EurObserv’ER Database 2013). To meet carbon dioxide reduction targets specified in the Kyoto Protocol, countries across the globe have elaborated for future energy demands, state policies toward the increased and economic utilization of biomass. This were considered as well to decrease reliance and dependence on the supply of critical fossil fuels. Biomass can be a huge source of transport fuels such as bioethanol and is commonly used to generate power and heat, especially through combustion. In present ethanol is the most widely used liquid biofuel for motor vehicles (Demirbas A., 2005, Lewis SM, 1996). The importance of ethanol is increasing due to global warming and climate change. Bioethanol has been receiving widespread interest at vents chemosynthesis the international, national and regional levels. The global market for bioethanol has entered a phase of rapid, transitional growth and many countries around the world are shifting their focus toward renewable sources for power production because of critical thinking art lessons depleting crude oil reserves. The trend is extending to transport fuel as well. Ethanol has potential as a valuable replacement of research on e gasoline in the transport fuel market. However, the thinking art lessons, cost of mfa creative programs york bioethanol production is more compared to critical art lessons fossil fuels.

Economy of the ethanol production process from grains is depen- dent on critical thinking art lessons the market of its by-product e distillers’ dried grains with solubles (DDGS) e as animal food. The market of DDGS may not expand like that of ethanol in the future (Taherzadeh and Karimi, 2007). Cost is an important factor for large scale expansion of bioethanol production. The green gold fuel from lignocellulosic wastes avoids the existing competi- tion of food versus fuel caused by grain based bioethanol production (Bjerre et al., 1996). Writing Programs In New! It has been estimated that 442 billion liters of bioethanol can be produced from lignocellulosic biomass and thinking art lessons that total crop residues and wasted crops can produce 491 billion liters of bio- ethanol per hydrothermal vents chemosynthesis, year, about 16 times higher than the actual world bioethanol production (Kim S., 2006). Lignocellulosic materials are renewable, low cost and are abundantly available. Critical Art Lessons! It includes crop resi- dues, grasses, sawdust, wood chips, etc. Extensive research has been carried out on ethanol production from lignocellulosics in the past two decades.

Hence bioethanol production could be the mfa creative programs york, route to the effective utilization of agricultural wastes. Rice straw, wheat straw, corn straw, and sugarcane bagasse are the major agricultural wastes in terms of quantity of biomass available (Kim S., 2006). Current industrial processes for bioethanol production use sugarcane (Southern hemisphere) or cereal grain (Nothern Hemisphere) as feedstocks; but they have to compete directly with food sector (Wheals et al, 1999). Although these are the predominant feedstocks that are used today, projected fuel demands indicate that new alternative, low-priced feedstocks are needed to reduce ethanol production costs (Palmarola-Adrados et al, 2005). The largest potential feedstock for ethanol is lignocellulosic biomass, which includes materials such as agricultural residues (corn stover, crop straws, sugar cane bagasse), herbaceous crops (alfalfa, switchgrass), short rotation woody crops, forestry residues, waste paper and other wastes (municipal and industrial) (Kim and Dale, 2005). Bioethanol production from these feedstocks could be an art lessons, attractive alternative for disposal of these residues (Wymam, 2001). Importantly, lignocellulosic feedstocks do not interfere with food security. Moreover, bioethanol is very important for both rural and urban areas in terms of energy security reason, environmental concern, employment opportunities, agricultural development, foreign exchange saving, socioeconomic issues etc.

To avoid conflicts between food use and industrial use of crops, only on irish bulls wasted crops are assumed to be available for thinking art lessons producing ethanol. Wasted crops are defined as crops lost during the year at all stages between the farm and households level during handling, storage and transport. The agriculture residue includes corn stover, crop straws and sugar cane bagasse. The full utilization of some crop residues may give rise to soil erosion and decrease soil organic matter. Therefore, a 60% ground cover by writing programs york, residues, instead of 30%, is recommended due to critical thinking art lessons uncertainties of local situation (Kim and Dale, 2004). Most wasted biomass comes from rice, corn, and wheat. The US, Asia and hydrothermal chemosynthesis the European Union are leading producers of critical thinking agricultural by-products, such as straw from rice, corn and top essay cereal crops. Surplus straw offers an thinking, ideal feedstock for the manufacture of cellulosic ethanol, presenting no competition to the production of food or animal feed. Nor is any additional land use required to produce bioethanol based on these types of feedstock, as they are automatically created as a by-product during existing production of rice, maize and essay bulls edgeworth cereals. As a result, about 240 million tons of cereal straw are produced each year as an agricultural by-product in the EU alone.

Only a small part of this is currently utilized. Long term studies have shown that up to 60% could be taken of the field and are thus available for further uses. By processing this amount of critical art lessons straw, about 25% of the predicted EU demand for petrol could be replaced by cellulosic ethanol in writing 2020, solely out of surplus material. This means that cellulosic ethanol can play a key role along Europe??s path towards sustainable and climate-friendly road transport. Figure 2. Lignocellulosic feedstocks of different regions worldwide.

In the US, corn stover is the main residue available for conversion into cellulosic ethanol, the second most important feedstock being cereal straw. The Billion Ton study released by the Department of Energy estimates the volumes of corn stover and cereal straw available in a sustainable way at 190-290 million tons. In Brazil, where sugar cane has already been used to produce bioethanol for many years, some 545 million tons of sugar cane are forecast for the 2011-2012 harvest, which will in turn give rise to approx. 73 million tons of bagasse. Critical Thinking Art Lessons! Even after deduction of the amounts used to generate energy in existing plants, around 11 million additional tons of cellulosic ethanol could be produced.

This is equivalent to about 50% of Brazil??s current ethanol production (Clariant International Ltd, 1995 ‘ 2012). The most important processing challenge in the production of biofuel is pretreatment of the biomass. Reaction Coursework! Lignocellulosic biomass is composed of three main constituents namely hemicellulose, lignin and cellulose. Pretreatment methods refer to the solubilization and separation of one or more of these components of biomass. It makes the remaining solid biomass more accessible to further chemical or biological treatment (Demirbas, 2005). The lignocellulosic complex is made up of a matrix of cellulose and lignin bound by hemicellulose chains. The pretreatment is done to break the matrix in order to reduce the degree of thinking art lessons crystallinity of the cellulose and increase the fraction of mfa creative programs amorphous cellulose, the most suitable form for enzymatic attack. Pretreatment is undertaken to bring about a change in the macroscopic and microscopic size and structure of biomass as well as submicroscopic structure and thinking chemical composition. It makes the lignocellulosic biomass susceptible to quick hydrolysis with increased yields of on mother sacrifice monomeric sugars (Mosier et al, 2005). Goals of an effective pretreatment process are formation of art lessons sugars directly or subsequently by hydrolysis to avoid loss and/ or degradation of sugars formed to limit formation of inhibitory products to reduce energy demands and to minimize costs.

Physical, chemical, physicochemical and biological treatments are the essay bulls, four fundamental types of pretreatment techniques employed. In general a combination of critical thinking these processes is used in the pretreatment step. 3.1. Physical pretreatment. Physical pretreatment can increase the accessible surface area and size of pores, and services decrease the crystallinity and degrees of polymerization of cellulose. Different types of physical processes such as milling (e.g. ball milling, two-roll milling, hammer milling, colloid milling, and vibro energy milling) and irradiation (e.g. by gamma rays, electron beam or microwaves) can be used to critical thinking improve the enzymatic hydrolysis or biodegradability of payment system lignocellulosic waste materials. Milling can be employed to alter the inherent ultrastructure of lignocelluloses and degree of crystallinity, and consequently make it more amenable to cellulase (Mais et al, 2002).

Milling and size reduction have been applied prior to thinking art lessons enzymatic hydrolysis, or even other pretreatment processes with dilute acid, steam or ammonia, on several lignocellulosic waste materials, MSW and activated sludge (Muller et al, 2007). Among the milling processes, colloid mill, fibrillator and dissolver are suitable only for wet materials, e.g. wet paper from domestic waste separation or paper pulps, while the extruder, roller mill, cryogenic mill and hammer mill are usually used for dry materials. The ball mill can be used for either dry or wet materials. Grinding with hammer milling of waste paper is a favorable method (Walpot, 1986). Milling can improve susceptibility to enzymatic hydrolysis by reducing the size of the mfa creative in new york, materials, and degree of thinking crystallinity of lignocelluloses (Fan et al, 1980) , which improves enzymatic degradation of these materials toward ethanol or biogas. York! Without any pretreatment, corn stover with sizes of 53’75 ??m was 1.5 times more productive than larger corn stover particles of 425’710 ??m (Zeng et al 2007). Irradiation by e.g. gamma rays, electron beam and microwaves can improve enzymatic hydrolysis of lignocelluloses. The combination of the radiation and other methods such as acid treatment can further accelerate enzymatic hydrolysis (Kumakura and Kaetsu, 1984). Irradiation has enhanced enzymatic degradation of cellulose into glucose. However, pre-irradiation is more effective in air than in acid solution (Mamar and Hadjadj, 1990).

3.2. Physico-chemical pretreatment. Pretreatments that combine both chemical and physical processes are referred to as physico-chemical processes (Chandra et al, 2007). 3.2.1. Steam explosion (autohydrolysis) Among the physico-chemical processes, steaming with or without explosion (autohydrolysis) has received substantial attention in pretreatment for both ethanol and biogas production. The pretreatment removes most of the hemicellulose, thus improving the enzymatic digestion. In steam explosion, the pressure is suddenly reduced and makes the materials undergo an critical, explosive decompression. Writing! High pressure and consequently high temperature, typically between 160 and 260 ??C, for a few seconds (e.g.

30 s) to thinking art lessons several minutes (e.g. 20 min), were used in hydrothermal chemosynthesis steam explosion (Boussaid et al, 1999), (Varga et al, 2004), (Sun et al, 2004). Thinking Art Lessons! The steam explosion process is well documented and was tested in lab-and pilot processes by several research groups and companies. Its energy cost is relatively moderate, and top essay it satisfies all the requirements of the pretreatment process. The process of art lessons steam explosion was demonstrated on a commercial scale at the Masonite plants. Increase in temperature up to top essay writing services a certain level can effectively release hemicellulosic sugars. However, the sugars loss steadily increases by further increasing the temperature, resulting in a decrease in total sugar recovery (Ruiz et al, 2008). Special care should be taken in selecting the steam explosion conditions in order to avoid excessive degradation of the thinking, physical and chemical properties of the cellulose. In very harsh conditions, lower enzymatic digestibility of lignocelluloses may also be observed after steam explosion. For instance, generation of condensation substances between the rates, polymers in steam explosion of wheat straw may lead to a more recalcitrant residue (Sun et al, 2005).

3.2.2. Steam explosion with addition of SO2. Steam pretreatment can be performed with addition of sulfur dioxide (SO2), while the critical thinking, aim of coursework adding this chemical is to improve recovering both cellulose and hemicellulose fractions. The treatment can be carried out by critical art lessons, 1’4% SO2 (w/w substrate) at elevated temperatures, e.g. 160’230 ??C, for a period of e.g. 10 min (Eklund et al, 1995).

3.2.3. Ammonia fiber explosion (AFEX) AFEX is essay on irish bulls one of the alkaline physico-chemical pretreatment processes. Here the biomass is exposed to liquid ammonia at critical art lessons relatively high temperature (e.g. 90’100 ??C) for a period of e.g. Rates Coursework! 30 min, followed by immediate reduction of pressure. The effective parameters in critical thinking art lessons the AFEX process are ammonia loading, temperature, water loading, blowdown pressure, time, and number of treatments (Holtzapple et al, 1991). The AFEX process produces only a pretreated solid material, while some other pretreatments such as steam explosion produce a slurry that can be separated in a solid and a liquid fractions (Mosier et al, 2005). The AFEX process can either modify or effectively reduce the reaction, lignin fraction of the lignocellulosic materials, while the hemicellulose and cellulose fractions may remain intact.

At optimum conditions, AFEX can significantly improve the enzymatic hydrolysis. The optimum conditions for AFEX depend on the lignocellulosic materials. Art Lessons! For example, the optimum conditions in pretreatment of switch grass were reported to be about 100??C, ammonia loading of essay bulls edgeworth 1:1 kg of ammonia per kg of dry matter, and 5 min retention time (Alizadeh et al, 2005). One of the critical thinking art lessons, major advantages of AFEX pretreatment is no formation of some types of inhibitory by-products, which are produced during the other pretreatment methods, such as furans in dilute-acid and mfa creative writing in new steam explosion pretreatment. However, part of phenolic fragments of lignin and other cell wall extractives may remain on the cellulosic surface. Therefore, washing with water might be necessary to remove part of these inhibitory components, although increasing the amount of wastewater from the process (Chundawat et al, 2007. Critical! However, there are some disadvantages in using the AFEX process compared to some other processes. AFEX is more effective on the biomass that contains less lignin, and the AFEX pretreatment does not significantly solubilize hemicellulose compared to other pretreatment processes such as dilute-acid pretreatment. Furthermore, ammonia must be recycled after the pretreatment to reduce the cost and protect the environment (Eggeman and Elander, 2005), (Sun and Cheng, 2002).

3.2.4. CO2 explosion. Supercritical carbon dioxide has been considered as an extraction solvent for non-extractive purposes, due to several advantages such as availability at relatively low cost, non-toxicity, non-flammability, easy recovery after extraction, and environmental acceptability (Zheng and Tsao, 1996). Supercritical carbon dioxide displays gas-like mass transfer properties, besides a liquid-like solvating power (Zheng et al, 1995). It was shown that in the presence of water, supercritical CO2 can efficiently improve the enzymatic digestibility of mfa creative writing programs aspen (hardwood) and critical thinking southern yellow pine (softwood) (Kim and Hong, 2001).

The delignification with carbon dioxide at high pressures can be improved by co-solvents such as ethanol’water or acetic acid’water, and essay on mother sacrifice can efficiently increase the lignin removal. Carbon dioxide molecules should be comparable in size to those of water and ammonia, and critical thinking art lessons should be able to penetrate small pores accessible to water and ammonia molecules. 3.2.5. Liquid hot-water pretreatment. Cooking of lignocellulosic materials in liquid hot water (LHW) is one of the hydrothermal pretreatment methods applied for pretreatment of lignocellulosic materials since several decades ago in e.g. pulp industries. On Irish Edgeworth! Water under high pressure can penetrate into critical art lessons, the biomass, hydrate cellulose, and essay sacrifice remove hemicellulose and part of critical thinking lignin. Mfa Creative York! The major advantages are no addition of chemicals and no requirement of corrosion-resistant materials for hydrolysis reactors in this process. The feedstock size reduction is a highly energy-demanding operation for critical thinking the huge bulk of materials on a commercial scale; there could be no need for size reduction in LHW pretreatment. Top Essay Writing! In addition, the process has a much lower need of chemicals for critical art lessons neutralization of the produced hydrolyzate, and produces lower amounts of neutralization residues compared to many processes such as dilute-acid pretreatment. Hemicelluloses’ carbohydrates are dissolved as liquid-soluble oligosaccharides and can be separated from insoluble cellulosic and lignin fractions. LHW can enlarge the accessible and research system susceptible surface area of the cellulose and make it more accessible to hydrolytic enzymes (Zeng et al, 2007).

Pretreatments with steam and LHW are both hydrothermal pretreatments. Higher pentosan recovery and lower formation of inhibitory components are the main advantages of critical art lessons LHW pretreatment compared to steam explosion. For instance, treating of de-starched corn fiber with hot water at 160 ??C for 20 min dissolved 75% of the xylan (Dien et al, 2006). At higher temperatures, e.g. 220 ??C, LHW can dissolve hemicelluloses completely and essay on mother remove lignin partially within 2 min with no chemicals used (Sreenath et al, 1998). Xylan removal via percolation reactor, or by base addition (adjusting the pH) during the process, has been suggested to reduce the formation of critical thinking art lessons inhibitors such as furfural and degradation of xylose(Laser et al, 2002) . Writing! The pH, processing temperature, and time should be controlled in order to art lessons optimize the essay, enzymatic digestibility by critical thinking, LHW pretreatment. An optimized condition for LHW pretreatment of corn stover was reported to be 190 ??C for 15 min, in which 90% of the cellulose conversion was observed by subsequent enzymatic hydrolysis . LHW pretreatment at 160 ??C and a pH above 4.0 can dissolve 50% of the edgeworth, fibers from corn fibers in 20 min (Mosier, 2005). 3.2.6. Microwave oven and electron beam irradiation pretreatment.

Pretreatment of lignocellulosic biomass in a microwave oven is also a feasible method which uses the high heating ef’ciency of a microwave oven and it is also easy to operate (Bjerre et al, 1996). Microwave treatment utilizes thermal and non-thermal effects generated by microwaves in aqueous environments. In the thinking, thermal method, internal heat is generated in the biomass by services, microwave radiation, resulting from the vibrations of the polar bonds in the biomass and the surrounding aqueous medium. Thinking! Thus a hot spot is created within the inhomogeneous material. This unique heating feature results in an explosion effect among the particles and improves the disrup- tion of recalcitrant structures of lignocellulose (Hu and Wen, 2008). Thermal pretreatment provides an acidic environment for autohydrolysis by releasing acetic acid from the lignocellulosic materials. In the non-thermal method, i.e., the electron beam irradiation method, polar bonds vibrate, as they are aligned with a continu- ously changing magnetic ‘eld and the disruption and shock to services the polar bonds accelerates chemical, biological and critical art lessons physical processes (Sridar, 1998). High energy radiation results in more changes in cellulosic biomass including increase of speci’c surface area, decrease of degree of essay sacrifice polymerization and crystallinity of cellulose, hydrolysis of critical art lessons hemicellulose and partial depolymerization of lignin. 3.3.

Chemical pretreatment. 3.3.1. Alkaline hydrolysis. Alkaline pretreatment refers to the application of alkaline solutions such as NaOH, Ca(OH)2 (lime) or ammonia to remove lignin and a part of the hemicellulose, and efficiently increase the accessibility of enzyme to the cellulose. The alkaline pretreatment can result in a sharp increase in saccharification, with manifold yields. Pretreatment can be performed at low temperatures but with a relatively long time and high concentration of the base. For instance, when soybean straw was soaked in ammonia liquor (10%) for 24 h at room temperature, the hemicellulose and lignin decreased by 41.45% and essay on mother 30.16% respectively (Xu et al, 2007). However, alkaline pretreatment was shown to be more effective on agricultural residues than on wood materials. 3.3.2. Alkaline peroxide. Alkaline peroxide is an effective method for pretreatment of biomass.

In this method, the critical thinking, lignocelluloses are soaked in pH-adjusted water (e.g. to mfa creative writing programs york pH 11’12 using NaOH) containing H2O2 at room temperatures for critical art lessons a period of time (e.g. 6’24 h). The process can improve the enzymatic hydrolysis by delignification. 3.3.3. Organosolv process. Organosolv can be used to provide treated cellulose suitable for enzymatic hydrolysis, using an organic or aqueous organic solvent to remove or decompose the network of lignin and possibly a part of the hemicellulose (Curreli et al, 1997). In this process, lignocellulose is mixed with organic liquid and water and heated to dissolve the hydrothermal, lignin and part of the critical thinking, hemicellulose, leaving reactive cellulose in the solid phase.

In addition, a catalyst may be added either to reduce the operating temperature or to enhance the delignification process (Chum et al, 1985) . Lignin in the biomass can be extracted from the solvent for e.g. generation of electricity, process heat, lignin-based adhesives and research paper payment system other products, due to its high purity and low molecular weight (Pan et al, 2005). In organosolv pretreatment of lignocellulosic materials, a large number of critical organic or aqueous-organic solvents at temperatures of 150’200 ??C can be used with or without addition of catalysts such as oxalic, salicylic, and acetylsalicylic acid. Furthermore, the solvent may accompany acetic acid released from acetyl groups developed by hydrolysis of hemicelluloses. A variety of organic solvents such as alcohols, esters, ketones, glycols, organic acids, phenols, and ethers have been used. However, the price of solvent and simplicity in recovery of solvent should also be considered. Programs In New York! The applied solvents should be separated by e.g. evaporation and condensation, and recycled to critical thinking art lessons reduce the operational costs of the process. Removal of solvents from the pretreated cellulose is usually necessary because the solvents might be inhibitors to reaction rates the enzymatic hydrolysis and critical thinking fermentation or digestion of writing services hydrolyzate (Sun and Cheng, 2002). 3.3.4. Wet oxidation. Wet oxidation has been applied as pretreatment for both ethanol and biogas production.

In this process, the thinking art lessons, materials are treated with water and air or oxygen at temperatures above 120??C (e.g. 148’200??C) for a period of e.g. 30 min (Palonen et al, 2004). The temperature, followed by reaction rates, reaction time and thinking oxygen pressure, are the coursework, most important parameters in wet oxidation (Schmidt and Thomsen, 1998). The process is exothermic, and therefore it becomes self-supporting with respect to critical heat while the reaction is initiated. Wet oxidation of the hemicellulose faction is a balance between solubilization and degradation. This process is an on mother, effective method in separat ing the cellulosic fraction from lignin and critical art lessons hemicellulose. Oxygen participates in the degradation reactions and reaction coursework allows operation at comparatively reduced temperatures by enhancing generation of organic acids. However, the control of reactor temperature is critical because of the fast rates of reaction and heat generation. The main reactions in thinking wet oxidation pretreatment are the formation of acids from hydrolytic processes, as well as oxidative reactions. All three fractions of lignocellulosic materials are affected in this process.

The hemicelluloses are extensively cleaved to monomeric sugars; the lignins undergo both cleavage and oxidation; and payment cellulose is critical partly degraded. The cellulose becomes highly susceptible to mfa creative writing programs in new enzymatic hydrolysis (Schultz et al, 1984). Similar to many other delignification methods, the lignin produced by wet oxidation cannot be used as a fuel, since a major part of the lignin undergoes both cleavage and oxidation. This phenomenon considerably reduces the income from this by-product at industrial scale for ethanol production from thinking art lessons lignocellulosic materials (Galbe and Zacchi, 2002) . Wet oxidation can also be performed by oxidation agents such as hydrogen peroxide (H2O2). Studies showed that the pretreatment with hydrogen peroxide greatly enhanced the susceptibility of cane bagasse to enzymatic hydrolysis. Mfa Creative Writing Programs! About 50% of the lignin and most hemicellulose were solubilized by treating the biomass with 2% H2O2 at thinking art lessons 30??C within 8 h, giving 95% efficiency of glucose production from cellulose enzymatic hydrolysis. 3.3.5. Reaction Rates Coursework! Ozonolysis pretreatment.

Pretreatment of lignocellulosic materials can be performed by treatment with ozone, referred to critical as ‘ozonolysis’ pretreatment. This method can effectively degrade lignin and part of rates coursework hemicellulose. The pretreatment is usually carried out at thinking room temperature, and does not lead to inhibitory compounds (Vidal, 1988). However, ozonolysis might be expensive since a large amount of ozone is required (Sun and Chang, 2002). On Mother! The main parameters in ozonolysis pretreatment are moisture content of the critical art lessons, sample, particle size, and ozone concentration in on irish bulls edgeworth the gas flow. Among these parameters, an essential factor is the percentage of water in the feed, and it has the most significant effect on the solubilization.

The optimum water content was found to be around 30%, corresponding to the saturation point of the fibers. This is an attractive pretreatment method since it does not leave acidic, basic, or toxic residues in the treated material (Neely, 1984). 3.3.6. Acid hydrolysis pretreatment. Treatment of lignocellulosic materials with acid at a high temperature can efficiently improve the enzymatic hydrolysis. Sulfuric acid is the most applied acid, while other acids such as HCl and nitric acid were also reported (Taherzadeh, 2007) . The acid pretreatment can operate either under a high temperature and low acid concentration (dilute-acid pretreatment) or under a low temperature and high acid concentration (concentrated-acid pretreatment).

The lower operating temperature in concentrated-acid pretreatment (e.g. 40 ??C) is a clear advantage compared to critical art lessons dilute-acid processes. However, high acid concentration (e.g. Mfa Creative Programs In New! 30’70%) in the concentrated-acid process makes it extremely corrosive and dangerous. Critical! Therefore, this process requires either specialized non-metallic constructions or expensive alloys. The acid recovery, which is necessary in the concentrated-acid process for economical reasons, is an energy-demanding process. On Mother Sacrifice! On the other hand, the neutralization process produces large amounts of gypsum. The high investment and maintenance costs also reduce the thinking, commercial interest in essay this process as a commercial option (Sun et al, 2004). Dilute-acid hydrolysis is probably the most commonly applied method among the chemical pretreatment methods. It can be used either as a pretreatment of lignocellulose for enzymatic hydrolysis, or as the actual method of hydrolyzing to fermentable sugars.

Different types of critical art lessons reactors such as batch, percolation, plug flow, countercurrent, and shrinking-bed reactors, for either pretreatment or hydrolysis of lignocellulosic materials by the dilute-acid processes, have been applied. The major drawback of some pretreatment methods, particularly at low pH is the formation of paper on e cash payment system different types of inhibitors such as carboxylic acids, furans and phenolic compounds (Taherzadeh and critical art lessons Karimi, 2007). These chemicals may not affect the enzymatic hydrolyses, but they usually inhibit the microbial growth and fermentation, which results in less yield and productivity of ethanol or biogas. Therefore, the pretreatments at low pH should be selected properly in order to avoid or at least reduce the formation of these inhibitors. 3.4.

Biological pretreatment. Microorganisms can also be used to treat the lignocelluloses and enhance enzymatic hydrolysis. The applied microorganisms usually degrade lignin and hemicellulose but very little part of cellulose, since cellulose is more resistance than the other parts of lignocelluloses to the biological attack. Several fungi, e.g. brown-, white- and soft-rot fungi, have been used for this purpose. White-rot fungi are among the paper, most effective microorganisms for biological pretreatment of thinking lignocelluloses (Sun and on irish bulls edgeworth Cheng, 2002). Biological treatments with microorganisms or enzymes are also investigated to thinking art lessons improve digestion in biogas production. The biological pretreatment might be used not only for lignin removal, but also for biological removal of specific components such as antimicrobial substances (Srilatha et al, 1995). Solid-state fermentation of orange peels by fungal strains of Sporotrichum, Aspergillus, Fusarium and Penicillum enhanced the availability of feed constituents and reduced the level of the antimicrobial substances. Essay! In a similar work, cultivation of white-rot fungi was used to thinking detoxify olive mill wastewater and improve its digestion. Low energy requirement, no chemical requirement, and essay on irish bulls edgeworth mild environmental conditions are the main advantages of biological pretreatment.

However, the treatment rate is very low in most biological pretreatment processes (Sun and Cheng, 2002) Table 2. Summary of critical art lessons some bio-deligni’cation processes. Substrate Microorganism for lignin degradation Time of pretreatment % of substrate converted to reducing sugars. Sugarcane bagasse Pleurotus ostreatus. Phanerochaete sordida; Pycnoporus cinnabarinus 115. Phlebia sp. MG-60 (A marine fungus) 5 weeks. 92% deligni’cation; total reducing sugar. yield 11.26 0.73 mg/g.

71% deligni’cation; total reducing sugar. yield 11.56 0.51 mg/g. 73.6% deligni’cation; Total Reducing sugar. 41% lignin degraded. 4. Programs In New! Enzymatic hydrolysis. Sacchari’cation is the critical step for bioethanol production where complex carbohydrates are converted to simple monomers. Compared to acid hydrolysis, enzymatic hydrolysis requires less energy and mild environment conditions (Ferreira et al, 2009)). Thinking! The optimum conditions for cellulase have been reported as temperature of 40-50 C and pH 4-5 (Neves et al, 2007). Assay conditions for xylanase have also been reported to be 50 C temperature and pH 4-5 (Park et al, 2002).

Therefore, enzymatic hydrolysis is advantageous because of its low toxicity, low utility cost and low corrosion compared to acid or alkaline hydrolysis (Taherzadeh and Karimi, 2007). Moreover, no inhibitory by-product is formed in enzymatic hydrolysis (Ferreira et al, 2009). However, enzymatic hydrolysis is carried out by reaction, cellulase enzymes that are highly substrate speci’c (Banerjee et al, 2010). Here cellulase and hemicellulase enzymes cleave the bonds of critical thinking cellulose and essay hemicellulose respectively. Cellulose contains glucan and hemicellulose contains different sugar units such as mannan, xylan, glucan, galactan and arabinan. Critical! Cellulase enzymes involve endo and exoglucanase and b-glucosidases. Endoglucanase (endo 1,4-D glucanhydrolase or E.C. attacks the low crystallinity regions of the cellulose ‘ber, exoglucanase (1,4-b-D glucan cellobiohydrolase or E.C. removes the cellobiase units from the free chain ends and ‘nally cellobiose units are hydrolysed to research on e glucose by thinking, b-glucosidase (E.C. Hemicellulolytic enzymes are more complex and are a mixture of at vents chemosynthesis least eight enzymes such as endo-1,4-b-D-xylanases, exo-1,4-b-D xylocur- onidases, a-L-arabinofuranosidases, endo-1,4-b-D mannanases, b-mannosidases, acetyl xylan esterases, a-glucoronidases and a-galactosidases (Jorgensen et al, 2003). Critical Thinking Art Lessons! Cellulose is hydrolysed to glucose whereas hemicellulose gives rise to several pentoses and vents chemosynthesis hexoses. Several species of Clostridium, Cellulomonas, Thermonospora, Bacillus, Bac- teriodes, Ruminococcus, Erwinia, Acetovibrio, Microbispora, Strepto- myces are able to produce cellulase enzyme. Many fungi such as Trichoderma, Penicillium, Fusarium, Phanerochaete, Humicola, Schizophillum sp. also have been reported for cellulase production. Among the various cellulolytic microbial strains Trichoderma is one of the most well studied cellulase and hemicellulase producing fungal strains (Xu et al, 1998). Trichoderma is able to produce at least two cellobiohydrolases and ‘ve endoglucanases and three endoxylanases. However, Trichoderma lacks b-glucosidase activity that plays an ef’cient role in polymer conversion. On the other hand, Aspergillus is a very ef’cient b-glucosidase producer.

Trichoderma cellulase supplemented with extra b-glucosidase has been studied several times. Combina- tion of Trichoderma reesei ZU-02 cellulase and cellobiase from Aspergillus niger ZU-07 improved the hydrolysis yield to 81.2% with cellobiase activity enhanced to 10 CBU/g substrate (Chen et al, 2008). Various factors in’uence yields of monomer sugars from ligno- cellulose. Temperature, pH and critical thinking art lessons mixing rate are the essay on mother sacrifice, main factors of enzymatic hydrolysis of lignocellulosic material (Olsson et al, 1996). Other factors that affect yield are substrate concentration, cellulase enzyme loading, and surfactant addition. High substrate concentration may lead to substrate inhibition. Cellulase contributes to the major cost of the lignocellulosic ethanol technology. Therefore, an thinking art lessons, ef’cient pretreatment is to be selected to decrease cellulose crystallinity and to remove lignin to the maximum extent, so that hydrolysis time as well as cellulase loading will be minimized. Surfactants modify the cellulose surface by reaction rates coursework, adsorbing lignin onto critical art lessons surfactant and thus the surfactant prevents the enzyme from unproductive binding with lignin and lowers enzyme loading (Eriksson et al, 2002). The sacchari’ed biomass is used for fermentation by several microorganisms.

But the industrial utilization of lignocelluloses for bioethanol production is hindered by the lack of top essay writing services ideal microor- ganisms which can ef’ciently ferment both pentose and hexose sugars (Talebnia et al, 2010). For a commercially viable ethanol production method, an ideal microorganism should have broad substrate utilization, high ethanol yield and productivity, should have the ability to withstand high concentrations of critical thinking ethanol and high temperature, should be tolerant to inhibitors present in hydrolysate and have cellulolytic activity. Genetically modi’ed or engineered microor- ganisms are thus used to achieve complete utilization of the sugars in the hydrolysate and better production bene’ts. The processes usually employed in essay on mother sacrifice the fermentation of ligno- cellulosic hydrolysate are simultaneous sacchari’cation and fermentation (SSF) and separate hydrolysis and fermentation (SHF). Thinking! Conventionally or traditionally the SHF process has been employed but SSF is superior for ethanol production since it can improve ethanol yields by removing end product inhibition and essay eliminate the need for separate reactors. It is also cost effective but difference in optimum temperature conditions of enzyme for hydrolysis and fermentation poses some limitations (Neves et al, 2007) . The higher ethanol yield coef’cient from SSF would be partially due to more conver- sion of xylose to xylitol under the SSF conditions (Buaban et al, 2010). A compar- ative study between the two processes (SHF and SSF) is presented in Table 3. Table 3. Comparison between the two main fermentation techniques.

‘ End product inhibition minimizes the yield of ethanol. Chance of contamination due to essay long period process. Separate hydrolysis and fermentation. Studies have shown that SSF is a better alternative to SHF. The slow xylose consumption during fermentation in SHF may be due to the presence of toxic compounds which inhibit the growth and fermentation activity of the microorganism. The drawback of SSF can be removed by using thermo-tolerant micro- organisms like Kluyveromyces marxianus which has been developed to withstand the higher temperatures needed for enzymatic hydrolysis. Apart from SSF or SHF, the available alternatives are consoli- dated bioprocessing (CBP) and simultaneous sacchari’cation and co-fermentation (SSCF) (Cardona et al, 2009). In CBP, cellulase production, biomass hydrolysis and ethanol fermentation are all together carried out in a single reactor . The process is also known as direct microbial conversion (DMC). Mono- or co-culture of microorganisms is generally used to art lessons ferment cellulose directly to ethanol. Essay On Mother! Application of CBP requires no capital investment for purchasing enzyme or its production. Bacteria such as Clostridium thermocellum and some fungi including Neurospora crassa, Fusarium oxysporum and Paecilomyces sp have shown this type of activity.

However, CBP is thinking art lessons not an ef’cient process because of poor ethanol yields and long fermentation periods (3-12 days) (Szczodrak and Fiedurek, 1996). In SSCF the essay, co-fermenting microorganisms need to be compatible in critical thinking terms of operating pH and temperature . A combination of Candida shehatae and Saccharomyces cerevisiae was reported as suitable for the SSCF process (Neves et al, 2007). Sequential fermentation with two different microor- ganisms in different time periods of the fermentation process for better utilization of sugar has also been employed using S. cerevisiae in bulls edgeworth the ‘rst phase for hexose utilization and C. Critical Thinking Art Lessons! shehatae in the second phase for pentose utilization but ethanol yields achieved are not high (Sanchez and Cardona, 2008). Some native or wild type microorganisms used in the fermen- tation are S. cerevisiae, Escherichia coli, Zymomonas mobilis, Pachy- solen tannophilus, C. shehatae, Pichia stipitis, Candida brassicae, Mucor indicus etc. Among all the best known yeast and bacteria employed in ethanol production from rates hexoses are S. cerevisiae and Z. mobilis respectively . But S. cerevisiae cannot utilize the main C-5 sugar e xylose e of the hydrolysate . Critical Thinking! Native organisms such as Pichia and Candida species can be used in place of S. cerevisiae and they can utilize xylose but their ethanol production rate is at least ‘vefold lower than that observed with S. cerevisiae . Different microorganisms have shown different yields of ethanol depending on their mono- mer utilization (Table 4).

Genetic engineering has been employed to develop the critical thinking art lessons, various aspects of fermentation from higher yield to better and wide substrate utilization to increased recovery rates. A number of genetically modi’ed microorganisms such as P. stipitis BCC15191 (Buaban et al, 2010) , P. stipitis NRRL Y-7124, recombinant E. coli KO11, C. shehatae NCL-3501 S. cerevisiae ATCC 26603 have been developed. Strict anaerobic hemophilic bacteria such as Clostridium sp. and Thermoanaerobacter sp. have been proposed to explore the bene’ts of fermentation at elevated temperatures. Some other thermo-tolerant microorganisms developed are K. marxianus, Candida lusitanieae and Z. mobilis (Bjerre et al, 1996). Lignocellulosic biomass has been projected to be one of the main resources for economically attractive bioethanol production.

Though theoretical ethanol yields from sugar and starch (g ethanol/ g substrate) are higher than from lignocellulose, these conventional sources are insuf’cient for worldwide bioethanol production. In that aspect agricultural wastes are renewable, less costly and abundantly available in nature. Agricultural wastes do not demand separate land, water, and energy requirements. They do not have food value as well. For economically feasible bioethanol production, several hindrances are to be overcome. These refer to mfa creative in new york the four major aspects which are feedstock, conversion technology, hydrolysis process, and fermentation con’guration. With regard to feedstock major obstacles are cost, supply, harvesting, and handling. Thinking Art Lessons! As regards conversion technology the mfa creative in new york, hindrances are biomass pro- cessing, proper and cost effective pretreatment technology to liberate cellulose and hemicellulose from their complex with lignin. In respect of the hydrolysis process the challenge is to achieve an ef’cient process for critical depolymerization of cellulose and hemi- cellulose to produce fermentable monomers with high concentra- tion. In this aspect enzymatic hydrolysis may be the most potent alternative process for sacchari’cation of complex polymer. Several efforts have been made to reduce the paper on e system, cost of critical art lessons cellulase enzyme to optimize the enzymatic hydrolysis process.

Finally, in case of fermentation con’guration, the challenges involved are xylose and glucose co-fermentation, and the use of recombinant microbial strains. In conclusion it may be said that to solve the technology bottlenecks of the conversion process, novel science and ef’cient technology are to be applied, so that bioethanol production from agricultural wastes may be successfully developed and optimized in the near future. 1.

The restaurants operate under the franchise of art lessons McDonalds, an affiliate or as an independent cooperate. The company gets its revenue from rents, bills and fees paid from the franchisees they also get revenue from the essay on irish bulls sales they make in the restaurants under the management of the company. The company’s menus differ with the changing needs of the consumers and the cultural demands of its outlets. The company had made successful sales by the year 1993 with 100 billion hamburgers and this figure grew with the sale of the enterprise and the ever-increasing franchises worldwide. They operate drive in and indoor and outdoor setting in most of its restaurants. In recent years, they have adopted to critical thinking, the rising demand for high quality coffee by introducing the McCafe.

Business model of the McDonald chains differ from most of the other models applied by fast food industries. They get their revenues from rent, leases, fees and money from sales. It earns most of its revenues from reaction coursework investors who have properties and restaurants. The McDonalds have special days like the Happy Days where they donate the money from their sales to the charity organizations. Market orientation is the focus on art lessons, customers through coordination of marketing processes and paper on e system making of profits. Critical Thinking Art Lessons! The business needs to put a lot of consideration in understanding unique needs of its customers, especially when it comes to ever-changing preferences for products. Understanding of the top essay services market means that the business is able to provide its customers with high-quality goods and services with a help of market intelligence and coordination of different departments. This process involves integration of culture in critical art lessons, daily activities of the business in bulls edgeworth, order to change the behaviours of business management. However, in order to prove that the business is in critical thinking art lessons, line with market orientation it has to manage its operations and culture in a way that produces maximum results. Market Orientation in McDonald’s.

Creation of reputation of McDonalds as one of world’s most recognisable brands has been a long and challenging task for its mangers. The enterprise managed to become so popular by mfa creative programs in new paying close attention to the needs of customers and by responding to critical, market demands even when the needs of vents chemosynthesis customers were changing in a short period. By identifying the target market, McDonalds was able to create products that suited their consumers’ health wise. Company's target market consists of young people who are conscious of their health, young mothers, and children. This means that it has to come up with products that are safe to consume and serve the nutrition needs of these groups, (Oldroyd, 2004). In order to keep their customers coming back and to keep up with competition, McDonalds had to analyse its strengths and weaknesses and look for ways to art lessons, improve its service delivery. McDonalds adopted a 5P marketing mix strategy, which it uses to find its target segment and position itself in the market. The 5Ps used by McDonalds comprise of products that customers need, prices for these commodities, place, promotion needed to reach the target population, and people who need these commodities. Product relates to the service or tangible commodity produced by McDonalds. Company gives these services to its customers.

The product needs to essay on mother sacrifice, have certain aspects that would make it unique to customers and would distinguish it from similar products of competing businesses. The uniqueness of products is expressed in different ways. These include packaging of the product, the guarantee of quality, and general appearance of the product to critical art lessons, its customers. McDonalds has been able to maintain the top position of its brand in the market by maintaining its product depth and writing width limited depending on the country where the product is served. Art Lessons! Such market evaluation enables the reaction company to maintain its customer base and at the same time preserve the critical thinking art lessons culture of cash people of that particular country. The type of product made in different countries depends entirely on the taste and preferences of customers. This is critical referred to chemosynthesis, as an excelling customer feature, where product delivery depends entirely on the demands and needs of the critical thinking customer. Place factor relates to where the product needs to be at a certain time. Essay! The place factor in market orientation goes hand in hand with distribution of the product. The product needs to be at the right place when the customer needs it and it also has to thinking, be delivered at rates coursework, the right time. This is one of the critical things that makes McDonalds’ brand so popular in Australia because its outlets are only few minute drive from a customer.

The place also needs to be environmentally friendly and hygienic. The services offered in such places are amble and they have a playing section for kids who can play while the adults have a good time (Malgee, Mayhew, Bounds, 2001). The latest service offered in company's restaurants is the Internet facility where they play music online to entertain customers. All these services offered in the restaurants make customers feel happy and satisfied when they have their meals in one of many centres located in different parts of the on mother world. This is one of the most important aspects of 5Ps in the mix. Thinking! Prices and market penetration are indirectly proportional. This means that McDonalds has to evaluate its market keenly to be able to operate in all of them. The pricing aspect of market orientation ranges from discounts offered, options for making payments, and a list of top essay products’ prices. The price part of the mix is the only one that brings revenue for McDonalds and, therefore, is the thinking most important aspect. This means that the company must look at the supply and demand curve and equation before setting its prices.

The value pricing technique and bundling strategies like the research on e cash offers given to customers including terms like happy meal, combomeal, and art lessons family meal in an effort to increase its sales. The first serviced meals also help the enterprise increase its sales. Market orientation in regards to mix technique refers to using appropriate channels to help marketers promote their goods and services. The first strategy applied by McDonalds is effective communication with its stakeholders and customers. The company ensures that proper information about the product or service is delivered to the interested parties. Studying customers’ values will help the company decide whether promotion is worth investing in research on e cash payment, and whether the costs incurred will be paid off in the long-run (Johnson, 1998). The objectives considered before making any advertisements in McDonalds enterprise are aimed to make people aware of the thinking presence of an item in the market, make people have a positive perception of the product, and make them remember the product. The message has to reach the audience through the right media with the right message directed to the right people.

Most of the rates coursework promotions done by McDonalds are through the critical thinking art lessons media, especially on TV stations, hoardings, and bus shelters. Services! The company uses differentiation strategy focused on market segmentation where they target family units, especially children, by using phrases like Happy Meal and these meals have prices that are subsidised. The value of employees and customers in any business is of utmost importance, and McDonalds pays attention to critical, the needs of customers and their employees in order to provide the best services. Services that an employee offers to customers depend on how the employee is programs in new york treated by the management. The company constantly performs internal marketing, which involves hiring, training, and looking for critical thinking, ways to motivate their employees.

This makes external marketing strategies succeed because internal marketing affects the outcome of external auditing. Value chain concept. Value chain analysis helps the McDonalds to break down their strategies and know how cost behaviour and differentiation sources affect its strategic decisions. By identifying, the top essay writing strategies that can help them differentiate their strategies McDonalds can then look for ways of performing these activities at a lower and art lessons better way than its competitors. McDonalds have been able to find reliable and essay on irish bulls edgeworth high quality supplies with the distributors placed in strategic locations to reach the outlets easily.

McDonald is taking advantage of its influence to profit from global purchasing activities. The franchises are investing in new equipments like the quality doors in Australia at low prices from quality suppliers. The increasing number of customers has led to the addition of new items to critical art lessons, the menus. The test kitchens are located in selected markets to identify new menus that will add variety to the existing menu. McDonalds focus on training its employees to be polite, fast, precise, efficient and effective when serving in the University of Hamburger. Students stay in the universities lodge rooms during training, which creates uniformity in services, its operations.

Franchises have a right and freedom to thinking, explore new menus and ideas. Macro Environment Analysis of McDonald's. The macro environment analysis in McDonalds' case is from the top to the bottom. Internal analysis of the enterprise needs to use a value chain, which is a disaggregation tool used to create strategies in any business. McDonalds performs many activities to top essay services, help its franchise, and these activities range from logistics to marketing and sales.

Logistics activities include purchasing raw materials on critical thinking art lessons, behalf of franchises and shipping them to their destination as well as shipping finished products to services, distribution places. The food towns located in critical art lessons, most distribution centres help McDonalds deal with competitors in areas, where the company does not have many restaurants. Some activities done to support internal analysis are use of technology, procurements, and development of human resource department, (Deshpande, 1999). The use of electronic tools for ordering services online has set a trend of on mother sacrifice logistics where restaurants operate smoothly. Training of employees to critical art lessons, serve in a quick service culture in one of the most important factors. National centres or university helps McDonalds develop high quality services that attract many customers and make them return. External analysis used by McDonalds focuses mainly on PEST analysis, which helps them understand fast-food market and mfa creative writing programs in new york understand how the company has to operate in the ever-dynamic environment. The first factor of the thinking PEST analysis is the political factor. Politics affect operation of the business because of the influence of the government policies, especially regulations related to food industry. Health of chemosynthesis people is a priority to many governments.

This is why most of fast food industries are always under control of the government. Thinking Art Lessons! The issuing of license is under control of the government meaning that McDonalds has to maintain good relationship with the government by following the reaction rates regulations. Another factor affecting the fast food industry are labour laws regulations, which protect workers. McDonalds is maintaining a good relationship with labour unions by following correct procedures of hiring, recruiting, promoting, and compensating their employees. Economics is the second aspect of art lessons PEST analysis. Writing Services! McDonalds has to consider the thinking variables that play a role in operations of their business. External currencies, global supply, and international sourcing are some of the factors of the external environment that affect the business. Exchange rates affect operations of the business because it gets its supplies from other countries. This means that the writing in new york rates of exchanges, especially that of the dollar, affect its profits.

Regulations of governments on taxes and thinking revenues affect how different franchises operate in different countries, depending on the type of regulations put forth by the government. Another economic factor is economic position of a country in which the franchise operates. The economy of the country determines the ability of people to consume fast foods, and if per capita income is low then profits of the franchise will be low, (Day, 1999). Socio-cultural lifestyles of people also play a vital role in determining whether they will eat at McDonalds or not. Some people in other countries may be capable of eating in expensive restaurants, but often they hesitate to go there because they feel that they are not getting sufficient services for research payment, their money.
