Research on new discovery in biology - Essay Example The coca plant has similar biochemical properties as those that produce alkaloids. The coca plant belongs to a group of plants with natural alkaloids, or nitrogen-containing compounds that produce diverse effects on the physiology of humans. The alkaloid compounds in these plants are proven to have strong pharmacological effects on people and are known to contain nicotine, caffeine, quinine, morphine, atropine, strychnine, and the illegal stimulant compound cocaine. The plants that contain alkaloids include the Solanaceae or potato family, the Brassicaceae or mustard family, and the Erythroxylaceae or coca family, to which the coca plant belongs. The close relatedness of these plants is not only justified by the fact that they all contain alkaloid compounds but also by the fact that they had a common ancestor around 120 million years ago and that the alkaloid compounds that they contain obey similar biochemical pathways. The significance of this fact is that if one were to uncover th e details of the natural synthesis of cocaine, then it is possible to study it from the point of view of the other plants to which the coca plant is related (How Plants Make Cocaine, 2012). ... The plant known as belladonna, which belongs to the Solanaceae family, produces the tropane alkaloid known as atropine, and the synthesis of this alkaloid was compared with that of cocaine in the coca plant. Although the biochemical pathway and mechanism involved in the synthesis of alkaloids is basically the same for all alkaloid-producing plants, and for both both belladonna and coca plants as well, the Max Planck Institute researchers hypothesize that the enzymes involved in the syntheses of different compounds must also be different from each other. The results of the experiment proved the hypothesis true when it was found out that the enzyme that produced the atropine in belladonna proved to be â€Å"completely different† from the one that eventually produced cocaine in the coca plant. This enzyme, which is known as AKR or MecgoR, is involved in the biochemical pathway of the synthesis of cocaine by converting the keto group into an alcohol residue, which is actually the same role assumed by the SDR, or short-chain dehydrogenase reductase enzyme in belladonna (How Plants Make Cocaine, 2012). Thus, although there was a basically similar pathway for the production of atropine and cocaine in both species of plants, the very small difference in the nature and identity of the enzyme that catalyzes the keto group towards the end of the pathway is the main factor behind the fact that the coca plant is able to naturally synthesize cocaine, and not another alkaloid compound. Moreover, it is very interesting for the Max Plank Institute researchers to find out that the synthesis of atropine in belladonna takes place in the roots of the plant before the atropine is transported to the leaves, while the synthesis of

Essay on Art and Gender (topic given in instractions)

On Art and Gender (topic given in instractions) - Essay Example This meant that nakedness was in the beholder’s eye. Further, the woman was blamed for everything experienced and thus she was made a subservient of the man as a punishment (Berger 47). The idea of women being made as objects to be stared at was worsened during the renaissance period, where the moment of shame dominated. The Nudes directed the shame more at the viewer rather than at each other. With time, the shame was used as a display of some kind. Though secular subjects were in use, Nudes still maintained the implication that women were aware of being gazed at. Consequently, they were not naked in their personal right, rather as naked in the eyes of men. According to Jones, another factor of Western Modernity that made it difficult for women to establish themselves as artists is seen in Berger’s illustration of the average oil paintings of the Nude, where the key character was never painted; the male spectator of whom everything had been accomplished. The European c onvention of not painting women’s body hair was symbolic. To them, hair symbolized passion and power, yet males perceived that these were their features. This contributed to women’s sense of inferiority and thus they lacked the motivation to become artists (Jones 230). Other factors which made it difficult for women to establish themselves as artists in western modernity Linda Nochlin reveals the failure of art and how the Western male viewpoint affected the establishment of women as artists. She refers to John Stuart Mill’s concept of how he viewed male domination as a major source of social injustice. Nochlin bases her argument that white male subjectivity was a factor that undermined women progress. Since men perceived themselves as superior, they focused on more noticeable art works and disregarded any effort made by women. Research with talented women in art work demonstrates that internal barriers also limited women to establish themselves as artists. The way women were raised and the cultural biases they experienced led to such barriers and lack of developing the belief in self, essential for a determination to highly creative work. In fact, some women remained in the background, in undesirable positions, as enforcers of other people’s ideas (Johnson 245). Creative potential in a number of women may be associated to lower-profile work. As men produced great works of art, most talented women made unconscious or conscious decisions to implement such men’s work. Women with art potentials, who had the capability to capitalize on this prospective in their work always portrayed single-minded purpose, made hard choices regarding their lives, and lacked support systems to help them come out. Another limiting factor to women’s establishment was societal-based. Such factors influenced or became an obstruction to women development in art. Nochlin wonders why there are no great women artists. From her analysis of women achi evements in art, she illustrates that great art by women was often underrated or disregarded in history (Nochlin 161). Further, research shows that though rational stimulation in homes tended to play a key role in the advancement of art, most women were not practically motivated or even permitted to involve in intellectual pursuits by their peers or families. They were traditionally offered less education than their male counterparts, and the society

The Concept of Globalization Essay Example | Topics and Well Written Essays - 250 words

The Concept of Globalization - Essay Example Businesses and markets across the world are now linked such that a business in one country can have customers from any part of the world. This is as a result of expanded business operations and easy access of world markets resulting to globalization of markets. Advancement in IT has aided in removing physical barriers like boundaries. Factors of production are central in the globalization process since nations exhibit differences in quantity and quality of these factors (Lechner, 2009). Nations that have less of one or more factors e.g. labor tend to seek it from others while they export what they have in surplus e.g. food in case land is put into proper use. Due to this interaction global institutions have emerged e.g. UN, IMF and The World Bank among others that control interaction between nations (Haugen and Mach, 2010). Some offer credit, others ensure peace and stability while others ensure credibility of international trade. Globalization has turned the world into one big marke t place where nations showcase what they have in plenty and seek what they are short of. Consumers are now free to shop for commodities from any part of the world. In the process goods and services, money and culture are exchanged making the world to be one big community.

Personal Growth Plan Essay Example | Topics and Well Written Essays - 1750 words

Personal Growth Plan - Essay Example Some people say God is not attainable through the organs of senses. Yet relation with God remains real. God reveals Himself through the people and the variety of events within lives of people. â€Å"Always a living Person is present, speaking, pleading, loving, working, and manifesting Himself whenever and wherever His people have the receptivity necessary to receive the manifestation† (Tozer, 2008). God is a person, who also has intimate relationships. Developing direct relationships on deep personal level is a proper aim for the person, devoted to Him. Every day I start with the meditation. I really go deep and enjoy prayer and the sense of overwhelming gratitude that streams from my heart. I really need to pray; I agree with the words â€Å"prayer is something we should do, even something we want to do, but it seems like a chasm stands between us and actually praying. We experience the agony of prayerlessness† (MacDonald, 2007). I meet other people with open heart and all the events I observe as those, sent by Him. I accept the daily challenges. Even if the life seems tough, I recognize all that is sent by God to challenge and improve me, thus I meet even seemingly bad events with gratitude. I honor Him for all the blessings and challenges he addresses to me. Devotional life seems to me not only to accept His presence in everything, but also remember this bliss is about relationships; this means not only to accept and gratify for what he gives but to serve as well. Every day has its opportunities to reveal the inner potential, own best virtues and creative force. Being a creator of own life and accepting responsibility for all own deeds and behaviors implies spirituality. This means understanding of own purpose, purpose of others and purpose of all the connections. All has its aim, its hidden and explicit meaning. There is a sense, a purpose of everything happening. All the simple things are touched by

The Morrison Company , Wheelwright , S.C and Myers, P. ( 2011), Assignment

The Morrison Company , Wheelwright , S.C and Myers, P. ( 2011), Harvard Business School - Assignment Example Breen can adopt the following strategies for bringing in the organizational change required to improve the performance. 1. It was found that personalization or customization of the smart labels is creating problems as Morrison was facing bottlenecks due to personalization delaying the packaging operation, moreover pharmaceutical companies required less customization as only 15% of orders were customized and its average price is $0.22 and represented two-thirds of Morrison revenue however 85% of retail orders were personalized with average price being only $.11. So it is recommended that personalization should be done only for large orders and not small orders and interchangeability manufacturing system should be introduced (Patil 2008). 2. Optimal Inventory Policy to be adopted: It was found that the current inventory policy of Morrison is inefficient as it is contributing towards significant lead time and suppliers are not able to supply 100 percent of the orders on time due to whic h Morrison is delivering orders 10 weeks later than the originally scheduled date. Therefore the inventory policy for materials has to change and optimum inventory policy should be adopted. Optimum inventory policy calls for two models, first through developing a simple model in which the relevant quantities and constant future demand flow are estimated in advance and second by developing an uncertainty model in which the random variable is demand flow is studied with probability distribution. Using two models, â€Å"the best maximum stock and the best reordering point are determined as functions of the demand distribution, the cost of making an order and the penalty of stock depletion† (Arrow et al 1950, p.1; Tempelmeier 2012). The optimum safety stock acts as a buffer production plan that takes into account the random uncertain events such as breakdowns of machines, random demands and late deliveries (Tempelmeier 2012). 3. ERP system to be launched: ERP system is used exten sively by both large and small and medium sized enterprises (SMEs). Breen should convince her CEO that ERP system provides both tangible and intangible benefits to the organization and its benefits are much more than its cost not vice versa. Tangible benefits realized from launching ERP system are reduction of inventory, personnel, financial close cycle, cost of IT, cost of procurement, and maintenance; improvements in productivity, order management, cash management, increase in profit and revenue and ensures on time delivery. Intangible benefits derived are increased visibility, improved processes, reduction in overall costs, customer responsiveness, more integration, flexibility, increase in performance of business and improved demand/supply chain (O’Leary 2004). It has become a must for integrating various business functions and for gaining competitive advantage however it must be customized, have support of top management (Fosser 2008). It can use materials requirement re source planning and manufacturing resource planning (Patil 2008). 4. Materials supplier sources should be increased: As it was found that

Persuasive Narrative in Rhetoric Essay Example | Topics and Well Written Essays - 1500 words

Persuasive Narrative in Rhetoric - Essay Example There are three main principles of narrative analysis. They are the principle of succession, principle of transformation, and the principle of mediation. The paper will use these principles in explaining the persuasive use of narrative rhetoric in Obama’s inaugural speech. Rhetoric is this case is the aspect of speaking effectively. The paper will also use narrative rationality to explain the persuasive effect of narrative in rhetoric. This paper will considerably focus on patho, logos, ethos, and their individual effect on persuasion in regards to narrative rational. Pathos, logos, and ethos are the three pillars of public speaking. They are the rhetoric styles of persuasion. I will use examples from the Obama inaugural speech to illustrate each of these points. The paper will then draw an informed conclusion on persuasive use of narrative in rhetoric. The Principle of succession is present in Obama’s inaugural speech. The Principle of succession relies on time and cha nge to explain the meaning of the sequential arrangement of objects, elements, and incidents in a narrative (Scharf, 2003). Everything is in time. Stage for the speech was perfectly set in front of building constructed by black slaves. The speech is filled by words signifying sequential events, â€Å"I stand here today humbled by the task before us, grateful for the trust you have bestowed, mindful of the sacrifices borne by our ancestors† (New York Times, 2009). These words seek to persuade the audience on his concern for the job at hand. The use of incidents like rising tides, still waters, clouds, and ranging storms is also sequential. They seek to persuade the audience that things and situations change with time and hence they should brace themselves for that change. Additionally, the use of incidents like the abandonment in the capital, when the enemy was advancing and the staining of the snow with blood, play a major role in persuading the audience that their history ha s not been good and hence the need to change it. This principle consequently leads to the principle of transformation. The principle of transformation relies on unities to define patterns that signify change in state of mind or state of affairs and hence defining the beginnings and endings. There is massive use of this principle in Obama’s inaugural speech. The phrase, â€Å"Starting today, we must pick ourselves up, dust ourselves off, and begin again the work of remaking America† (New York Times, 2009) signify change in the state of affairs. These words seek to persuade the audience that it is time to act towards good for America. Other words that signify change of state of mind are, â€Å"Our capacity remains undiminished, but our time of standing pat, of protecting narrow interests and putting off unpleasant decisions† (New York Times, 2009). These too persuade the audience that change is irresistible at this time. It marks the beginning of putting off unple asant decisions and the end of protecting narrow interests. Moreover, from the energy in his words and the applause that he receives it is sure that Obama and the American people are ready for this change and hence the eminent success in narrative persuasion. This principle additionally leads to the principle of mediation. The principle of mediation relies on desire and ability to get a better understanding of the environment hence
