A Meta-Analysis of Transcriptomic Footprints Disclose Specificity of Research Paper

A Meta-Analysis of Transcriptomic Footprints Disclose Specificity of Reactive Oxygen Species Signaling in Arabidopsis Study - Research Paper Example These species also have a signaling role and are very important in carrying out this signaling function, which is evident during various developmental processes such as allelopathic plant-plant interactions, cell elongation, and division, programmed cell death. It may also be noted during environmental processes as well as biotic and abiotic stress responses. Since a major part of metabolic activities are highly oxidizing, or have very intensive rates of electron flow; as a result, they tend to produce high levels of ROS. The signaling role is important because it produces the control and regulation of various biological processes and the ROS appear to have a dual role for these ROS in plant biology; both as the toxic by-products of aerobic metabolism as well as regulators of the various cell-based processes associated with growth, development as well as patterns of defense. Hence, at the outset, the significance of this study lies in the fact that the importance of reactive oxygen species has been identified, i.e., as a toxic byproduct of the biological processes which tends to function as a signal to regulate the various cell processes. Moreover, another aspect that could also be deduced in relation to this study and the findings of other researchers was outlined in the study that the ROS activity can lead to the oxidative destruction of cells. This is important because it shows that in so far as the evolution of aerobic organisms is concerned, the development of efficient ROS scavenging mechanisms is likely to be a causal factor in such evolution. The oxidative destruction of cells is caused by the partially reduced or activated derivatives of oxygen such as hydrogen peroxide and hydroxyl radical. The genome-wide microarrays provide the means to access the changes in transcripts arising out of an alternation in specific types of ROS. For example, whe n light stress occurs, there is an expression of heat shock proteins, which can be controlled by systolic H2O2.  

The Medieval Era Essay Example | Topics and Well Written Essays - 1000 words

The Medieval Era - Essay Example The Medieval Era or the Middle Ages was characterized feudal system that mostly exalted Knights, Nobles, and Kings. The era mostly lasted between the 5th and the 15th century and was eventually replaced by the Renaissance or the Age of Discovery. During this period, there existed a division amongst Knights including a code of chivalry as noted in Charny’s book A Knight’s Own Book of Chivalry. It means chivalry was a moral, religious, and social code in the Middle Ages in defining a knightly conduct. Additionally, knights of that time had sore lives that depended on charity, justice and faith. Therefore, maintenance of high level of morality was a defining point of morals. However, from 1437 to 1449, Early Modern Period of the Medieval Era experienced certain fundamental changes that later shaped Europe extensively. For instance, the invention of the printing press by Johannes Gutenberg heralds a new era of publishing both news and literature in societal domain. The development equally expanded accessibility throughout Europe hence widening readership amongst the citizens. In 1442, the eruption of the Battle of Szeben results to the third victory orchestrated by Hungarian forces under the leadership of Janos Hunyadi. The war is against the Ottoman forces. Also known as the Battle of Sibiu or the Battle of Hermannstadt, the war claimed about 15-20, 000 Ottoman soldiers whiles the Hungarian side lost approximately 3-4,000 men. Unfortunately, the victory could not be translated in the Battle of the Iron that was fought close to the Danube (Newman 145). Another interesting development entails the Battle of Varna that resulted to victory for the Ottomans. Notably, it was a determining battle to reclaim the Crusade of Varna that resulted to the massive defeat of Hungarian-Polish forces and the ultimate death of their leader, Wladyslaw III. On that note, the timeline between 1300 and 1600

New Technologies, New Dependencies Essay Example | Topics and Well Written Essays - 1500 words

New Technologies, New Dependencies - Essay Example According to Griffiths, computers have enhanced communication on a global spectrum; this has happened not only because of the improved functionality of different computers, but also due to social media tools that have transformed the world into a global village (Griffiths). The development of computers has led to an increasing human dependency on the micro-chip. People hold various opinions regarding the development of this device. Many of them feel that it is a great way and it has proven to benefit many people and has revolutionized the entire world. However, others hold opinions against this device and feel that human beings have shown too much dependency on the computer. Technology endeavors have led to increase in business returns, enhanced consumer relationships, and have raised the standards of competition to the benefit of the market and have highlighted the positivity of the computer device in this era (Lai). The history of computers goes back to the time when the Abacus was used in 300 BC used by the Babylonians. Initially, in the abacus pebbles were used for counting. The word â€Å"calculus† is a Latin word which means pebbles. Human beings were the initial computers so to speak. They would carry out tasks that now computers are programmed to do. Also the computer is developed in a similar way like the human being in which a hard drive, stores memory similar to the human brain, the Central Processing Unit plays the role of the human heart, making the machine work. Human beings wanted work to be done fast, without any chaos, in an organized and systematic manner. Inventors had been searching for a way to do work fast and flawlessly. This actually led to the invention of the computer, that is work is done in a mechanized way. In 1936, the first proper freely programmable computer was invented. It was invented by Konrad Zuse. Slowly and gradually computer production developed, and in 1953 IBM (International Business Machine) became the latest co mputer system. Since then, there is constant development and improvement in various computer systems, and scientists are more and more focused on trying to develop the most user-friendly device possible. In 1976 Steve Jobs set up his company with the name of Apple and stars to produce the first personal computer kits. Apple kept improving and bringing out better and more advanced and latest models of computers. For Apple, The new â€Å"in† thing that has now come into the market is the touch. IPhones, IPads and IPods are the latest gadgets produced. Then, in 1985, Microsoft Windows made its grand entry into the computer market and has made itself a huge name and earned a major chunk of the market share. By that time, a subtle competition began between the Apple and Microsoft who hold together most of the market share in today’s world. In the 1990’s, particularly from 1992-1998, real businesses experienced an increase on an average of 44% per year on computer pri ces. Computer companies would sell their hardware’s and software’s convincing buyer that this was the latest and most reliable parts that promised improved productivity (Whelan). Now coming to the question of why there is an argument between people who feel that computers are an advantage opposed to those who feel it is a nuisance. Well, people have made it into one because of too much dependency on the device. But is there any other

Media - Essay Example To emphasize this theme of darkness from the beginning, Conrad’s narration took place in the Thames tidal estuary. Marlow recounted that London in ancient times was itself a dark place from the point of view of the Romans. This theme of darkness lurking beneath the surface would appear often as Conrad described the character of Kurtz and through his narrator with his passing sense of understanding with the Africans. In a paragraph, for instance, Marlow said: I tried to break the spell [Marlow says] – the heavy, mute spell of the wilderness – that seemed to draw him to its pitiless breast by the awakening of forgotten and brutal instincts, by the memory of gratified and monstrous passions. This alone I was convinced, had driven him out of the edge of the forest, to the bush, toward the gleam of fires, the throb of drums, the drone of weird incantations†¦ He had kicked himself loose of the earth†¦ His soul was mad. (p. 183) The darkness theme can also be found in other themes in the novella such as the naivetà © of Europeans regarding the various forms of darkness in Congo, the European colonialists’ abuse and exploitation of the Africans and the human nature’s tendency of duplicity. The Heart of Darkness has at least 10 film or television adaptations after its publication.. A problem in regard to adapting this work of fiction is how to translate the first person narrative first, in the radio adaption; and, second, in film adaptations later on. Marguerite Rippy cited the approach of substituting the eye of the camera for â€Å"I† of Conrad’s narrator. (p. 30) Here, the camera would become Marlow, whose voice would be heard offscreen. This has been implemented in Orson Welles’ adaptation of the novella. He successfully adapted the material in 1938 and that he was eager to reproduce the material on film. Film adaptations of the Heart of Darkness have focused on different interpretations. For example,

Discussion 11- reporting net income Assignment Example | Topics and Well Written Essays - 250 words

Discussion 11- reporting net income - Assignment Example Habitually, EPS has been hugely applied but it is susceptible to critical errors in calculation. Customarily, EPS is mostly influenced by the model of the accounting policies adopted by the company. Yields gained from the growth percentages is mostly perplexing and may be misleading or even meaningless with regards to small base and even negative earnings collected from past periods. EPS becomes distorted in cases when the company re-tracks share buy back in instances when the company repurchases its main shares thus reduces the amount of the shares placed in issue (Pratt, 2013). This provides automatic increment on the EPS figures. While most companies would boats of elevating the EPS, it is enormously vital to note that earnings must increase which is the desire of the investor. Even after placement of savings on the account of the investor, the cash should earn additional income in terms of compound interest (Peters, 2013). Normally, the EPS does not consider the company’s dept level and concurrent leverage which are the factors that influence the direction taken by the investor in selection of the future investments. EPS are repeatedly configured by the mergers and other entailed acquisition which has least regards for the actual value that is created (Pratt,

Saint Augustine Research Paper Essay Example for Free

Saint Augustine Research Paper Essay Augustine was a bishop of Hippo Regius, a Latin philosopher and theologian. He was born in 354 in the town of Thagaste in Roman Africa. Growing up with a Pagan father and a Christian mother, Saint Augustine endured many experiences from which he produced a book of confessions. In this book he writes about his life and struggles with evil desires. He struggled with greed, gluttony and lust, which are three among seven of the deadliest sins. His main struggle was within faith and religion concerning sexual restrictions and church regulations. He overcomes these struggles when he finds his faith. The encounters of evil Saint Augustine battles with fluctuate throughout his life. In his book of confessions he states that committing greed and gluttony brought joy to him. He loved anything that would amuse him such as chariot racing, gladiator fights and theatre. He would venture in drinking; gambling, stealing and he participated in barbaric pranks on people. He focused more on his own pleasures other than helping others. What saved him was his mother, Monica, who prayed for Augustine’s wickedness to wither. Monica’s prayers were answered when she received a dream from God. During this time he became a teacher and over the years he saw that what he use to enjoy was dull and senseless. Slowly his immoral practices became nothing but regretful memories. His mother then started to persuade him to become a Christian in which he did. He found his faith and began a new life without sin. His most grueling struggle was the sin of lust. He was not chaste nor did he abide Christian precepts. In his book he describes that his actions were done to avoid mockery and to also be accepted by his peers. When his mother was directing him towards the good she proposed that he should marry. Augustine married a 10-year-old child and when waiting for her to evolve he had an affair. By overcoming this obstacle he finally converted to Christianity and refrained from any form of sexual pleasure. He states, â€Å"The evil was not in the sexual act itself but in the emotions that accompany it. He also considers lust to be an obstacle to obtain the virtuous life. Saint Augustine had a constant battle with himself towards church policy and restrictions. He struggled with the limitations towards sexual intentions, which included him to be faithful to his significant other and live a monogamous lifestyle. He disagreed with this because his number one struggle was his erotic desires. This was one of the reasons as to why he gradually con verted to Christianity. His struggle to adhere faith was one of the obstacles to find his identity. He overcame this with the help of his mother and her prayers and he soon came to realize that his past was full of sin so he cleansed himself and became who he is known to be today. Saint Augustine had a life of sin. He struggled with lust, gluttony, greed, faith and religion. He then found himself and became a Saint. Like anybody else Saint Augustine was human, he faced many obstacles concerning evil practices but in the end he overcame these struggles when faith prevailed.
