Recent biotechnological approaches that have been used to enhance the Essay

Recent biotechnological approaches that have been used to enhance the yield and diversity of amino acids, vitamins, antibiotics - Essay Example These enrichments are only possible with Biotechnology. In the agriculture sector, many technologies are used such as genetic manipulation and gene transfer, development of recombinant vaccines, molecular markers, DNA-based disease diagnosis and characterization, embryo transfer and in vitro propagation of plants. In the food industry, the food processing is the main part where biotechnology intermission is required. For the improvement of the bacterial strains, genetic modification of the strains for the food processing microorganisms by the identification, characterization and alteration is done. Thus biotechnology has vast applications in many fields. Biofuels: As the fossil fuels are very limited, the search for the alternative methods that are renewable and safe are looked upon. The biological fuels such as ethanol, methane, hydrogen etc., are increasing day by day. To improve the production quality of these biofuels, the biotechnological approaches are used. The drawbacks of th ese methods such as low yield, high cost of feed, ad lack of active micro organisms can be overcome by using biotechnological approaches. ... Here the metabolic pathway is altered. The glucose metabolism towards the metabolic pyruvate formate lyase pathway by interrupting the succinate producing and lactate producing pathways. (Yoshida et al. 2006). By this technique the yield of hydrogen was increased from 1.08 mol/mol glucose to 1.83 mol/mol glucose which is 190 percent increase in the yields when compared to the wild strain hydrogen production. (Yoshida et al. 2006). The maize is used for the production of biofuel nowadays. The distillery soluble waste obtained after the ethanol production called as dried distiller grain soluble (DDGS), is usually left out as cattle feed. The researchers have found that this DDGS has a lot of nutritional value and if the feed is improved with amino acid and vitamin content, it can be used for swine and poultry. (Ufaz and Galili 2008). Lignocellulostic biomass is widely used as the main source of sugars for the fermentation to biofuels and other energy sources. These sugars are present b ound to the plant cell walls. The process of overcoming these barriers by the use of some break through technologies is termed as â€Å"biomass recalcitrance†. (Tomes and Lakshmanan 2010). Pretreatment of the biomass and then using it as the raw material for biofuel production will result in better yield. As lignin is not degraded easily by the protease enzymes, some modification to the substrate is very essential. Lignin hinders its active site form the enzymes and also binds reversibly to the proteins, because of this nature of lignin the enzymatic conversion is very less. So an alternative approach of increasing the pore size of the biomass can help to increase the enzymatic activity. Enzymes such as cellulase and hemicellulase are used for the

Women as Spies in the Civil War Essay Example | Topics and Well Written Essays - 2750 words

Women as Spies in the Civil War - Essay Example This research will begin with the statement that although the role of espionage has been admitted to be a very important factor through the entire course of the American Civil War in most historical records, it has been denied the deserving respect in terms of detailed narratives elaborating upon the actual significance of the roles played by spies. This holds true even more in case of women who served as undercover agents.   The author has rightly presented that this unavailability of detailed mention in records results primarily from the nature of the job itself. Often, records would be destroyed to protect the identities of the agents by themselves or by other officials. So, the historian addressing this issue would have to seek out often intentionally obscured and carefully camouflaged tracks by the agents themselves, officials of both the governments and last but not the least, time. The paper tells that proper chronicling of Civil War intelligence activities is thus a strenuo us challenge due to the absence of records, the absence of access to records, and also the dubiousness of the available records. The confederacy’s state secretary, Judah P. Benjamin burned all records related to intelligence activities that he could find when the news of the Federal troops entering Richmond came. On the other hand, till 1953, Intelligence records belonging to the Union were kept sealed in the National archives.

Staff development Assignment Example | Topics and Well Written Essays - 250 words

Staff development - Assignment Example In the evaluation, it is more about what they have done for the organization and whether it was I line with the goals, mission and vision of the organization or not. In evaluating staff performance, the manager should allow for the employee to discuss their self-evaluation, what their needs are as well as the differences in the current and previously carried out evaluations. This allows bonding time and more communication as the interviewer and interviewee have interacted in the past hence an unstructured interview (Edenborough, 2007). In the staff selection interview, the manager takes all the charge and the staff is not allowed the open communication and personal input. This is necessary in order to create barriers and level of authority from the initial start with the employee. Managers that are too open may lead to employees that slack in performance, don’t take authority too seriously and hence leading to poor performance and manager-staff relationship in

Cicero and liberty in modern era Term Paper Example | Topics and Well Written Essays - 2000 words

Cicero and liberty in modern era - Term Paper Example Back in the times, a person’s worth was determined based on his family. Marcus Cicero was therefore a lucky man and a worthier Roman citizen. He was born to senior Roman citizen, one serving in the equestrian order and had good connection within Rome. The roman society attached very little worth on its women, therefore no much is written about Cicero’s mother. However, it is understood that she was a humble housewife who effectively took care of his two sons. Cicero was born in 106 BC in a small hill town southeast of Rome called Arpinum. It was here that his father owned a fortune. Cicero was bright from childhood, he took much pride in studying works of previous iconic personalities, and most of his readings were political and philosophical manuscripts. He therefore became knowledgeable on the history and the structures of the Roman government (Tempest 47). Cicero derived his greatest motivation to read from his surname which he never liked and therefore never used, C ognomen. Loosely translated, this name meant that Cicero was named after one of his ancestors who had a cleft on his left nose. This became a joke and an origin of ridicule among his family and peers. He therefore resented the name and from the public ridicule and humiliation, he denied himself a social life as a child and took to books. His childhood dream was to become a politician, he read all the manuscripts and books he could find on politics, through his father’s connections, he gained access to the best literature material within Rome and in the process of learning politics, he redeveloped his other abilities. He studied philosophy and was a fosterer of rational thought on public management, through his oratory ability; he became a charming leader one capable of championing for an idea and through rationalization make it come through. He had an effective and an informed way of arguing his issues thereby winning the love of the common Roman citizen while gaining respect among his accolades (Stockton 44). The first half of the first century was characterized by chaos in the Roman Empire, Gaius Julius Caesar, rose to the helm of leadership amidst several oppositions and counter accusations. He therefore out rightly turned into a dictator in a bid to retain his rule. Cicero opposed his leadership and kept championing for the return to the previous republican type of governance. Through his hawk eyed analysis of the Roman constitution and other laws and statutes, he developed philosophies illegitimating Julio Caesar’s dictatorial rule. He soon began becoming a darling to the public. His fame with the citizen climaxed at about the same time that Julio Caesar was murdered. Mark Antony took over the governance of the emperor in unclear circumstances and introduced systems similar to those of his predecessor. Once again, Cicero became a critic of the governance and would always attack Mark Antony in most of his public speeches. Mark Antony labeled him an enemy of the state which back them was synonymous to being charged with treason in the modern day society. he had two options which included either surrendering to the state

Outline the development of global ecotourism over the last 30 years Essay

Outline the development of global ecotourism over the last 30 years. What has fuelled its rise What challenges has it faced - Essay Example This enables subsequent generations to experience regions relatively undisturbed with by human activities. A number of university courses utilize this explanation as the functioning definition of ecotourism. In general, ecotourism contends with the functioning components of the natural habitat. It concentrates on environmental sustainability, socially responsible travel, and personal growth. It characteristically entails travel to areas where cultural heritage, flora, and fauna are the chief attractions (Fennell 1999, p. 7). This paper will look at the objectives and development of global ecotourism over the last 30 years, what has caused its development and the challenges it faces. Objectives Ecotourism is about sustainable travel, uniting communities, and conservation. In addition, ecotourism has a number of objectives. First, it aims to lessen impact; ecotourism is aimed at providing insight to tourists on the effects of human beings activities on the surrounding, and to promote a better awareness of the natural environment thus decreasing effects. Second, it aims at building cultural and environmental respect and awareness. This means that both natives and travellers will have personal development while taking care of the environment. Third, ecotourism intends to give positive experiences for both hosts and visitors through explorations in isolated areas. Fourth, it aims to offer absolute financial advantages for conservation; the money got from the travels will help take care of these regions. Fifth, ecotourism seeks to enhance understanding to environmental, social, and political climate of host nations; travellers have the opportunity to comprehend different cultures and origins. Finally, ecotourism intends to appreciate local culture through gaining knowledge of the different practices (Page & Dowling 2002, p. 26). In general, ecotourism entails processes that lessen the negative components of regular tourism on the habitat and promote the cultural vera city of the native people. Therefore, ecotourism frequently interests advocates of social and environmental responsibility. Development of Ecotourism Ecotourism and additional forms of sustainable travel have their foundations in 1970, with the environmental movement. Individually, ecotourism did not become popular as a travel notion till the end of 1980. During this period, escalating environmental consciousness and an urge to travel to natural areas as opposed to manmade tourist areas made ecotourism attractive. Since that time, a number of organizations focusing in ecotourism have been created and a number of individuals have become ecotourism professionals. In July 1983, Hector Ceballos-Lascurain developed and advanced the expression ecotourism when he was both the president of PRONATURA and the director general of Standards and Technology of SEDUE. PRONATURA was pushing for the preservation of the wetlands in the north part of Yucatan as feeding and breeding areas of the Americ an Flamingo. There is also an assertion that ecotourism was employed in previous times. It is claimed that an adventurer and academic, Claus-Dieter Hetzer, developed the phrase in 1965. It is also argued that he was the first person to run ecotours in the Yucatan region in the early parts of 1970. Moreover, sustainable development, ecotourism, jungle tourism, and responsible tourism have become widespread notions since the middle periods of 1980.

In what ways did US officials act to build a global order under US Essay

In what ways did US officials act to build a global order under US leadership, during and after World War Two, and what were the essential features of that order - Essay Example According to Hudson (2008), foreign policy is â€Å"the strategy or approach chosen by the national government to achieve its goals in its relations with external entities† (p. 12). Kaufman (2010), in turn, writes that the formulation of foreign policy denotes a process of reassessing certain policies – either previous or existing ones – as a result of changing circumstances. In general, the process of foreign policy decision making not only involves various domestic actors aiming for certain outcomes, most notably the national government, but is also highly dependent upon regional and global developments, factors, and forces, which constitute the particular international context. While most of the foreign policy decisions, whether being concerned with international trade, economic and diplomatic relations, immigration policies, etc., could be considered relatively routine, there are extraordinary ones where the stakes appear to be extremely high (Kaufman, 2010), like the formation of strategic alliances, decisions on whether to go to war or make peace, etc. On the other hand, even those foreign policy decisions, which are generally considered routine, inevitably attract more attention in election years, or when an extraordinary event or development occurs (Kaufman, 2010). Thus, as noted by Kaufman (2010), foreign policy is not only of concern to diplomats or bureaucrats but can affect everyone. Two conceptions of what the American type of government should consists in had been put forward at the very dawn of the United States – that of Thomas Jefferson and Alexander Hamilton (Kaufman, 2010). While Jefferson didn’t conceal his animosity towards à ¢â‚¬Å"a very energetic government† (US Department of State, n.d.; Peterson, 1993), Alexander Hamilton, in turn, argued in favour of a strong relationship between the national government and big business, order, efficiency, as well as for the necessity of integrating the country – under favourable terms however – into the international system (Kaufman, 2010). Even though these views seem opposite to each other, historians aptly point out that Hamilton and Jefferson â€Å"often arrived at the same practical conclusion† (Harper, 2004, p.104). Not surprisingly therefore, the principles of economic development and non-interference in the European conflicts remained â€Å"a matter of consensus†, and the pillars of American foreign policy until the early twentieth century (Harper, 2004, p.104). Nevertheless, the purchase of Louisiana from France during the presidency of Thomas Jefferson and the War of 1812 signalled more or less a considerable shift in US foreign policy behaviour. The success of the purchase of Louisiana could be deemed to have set the precedent for buying the strip of land along the American–Mexican border in 1853 – named after the American general and diplomat James Gadsden, aka the Treaty of La Mesilla (Ibarra, 2004; Yale Law School, n.d.) – as well as Alaska from the Russian empire in 1867. The War
