Philosophy and nature of science class (PhD level)- about Critical Essay

Philosophy and nature of science class (PhD level)- about Critical Analysis of historical Science Example (DNA) - Essay Example The discovery of the DNA in the 19th century is regarded as one of the most significant biological discoveries of all time. The understanding of the structure and functions of DNA has impacted considerably in the science and medicine fields, with the most noteworthy impact being illustrated in the evolution of man. The discovery of the DNA has since made possible the identification of genes, which in turn permits scientists to acquire more knowledge and perception about the nature of diseases. Consecutively, this has made it permissible for the scientists to be able to diagnosis diseases easily, and by so doing makes it possible to the create drugs to treat these diseases, a quest which is regarded as a fundamental element in the evolution of mankind. In biology, Deoxyribonucleic acid (DNA) is the genetic factor found in human beings and other life forms and the DNA elements that support this matter are referred to as genes. Nearly all the cells in a creature have similar DNA, the majority of it being centralized in the cell nucleus where it is referred to as nuclear DNA (Neale, 2006). Conversely, we note that trace amounts of DNA are found in the mitochondria which are termed as mitochondrial DNA or basically mtDNA. In DNA data is stored in codes comprising of four chemical elements, namely: adenine (A), guanine (G), cytosine(C) and thymine (T) (Watson, 2004). Nevertheless, we comprehend that, in human beings, DNA comprises of more than a billions elements, which are more often than not similar in all humans. The orders in which these elements appear establish the availability of elements to build and sustain a being which can be likened to the order of letters that form different words and sentences. The four DNA elements merge in a predetermined sequence, in that, A binds with T while C binds with G which results in the arrangement of elements termed as base

The Development of American Science and Technology in the Eyes of Essay

The Development of American Science and Technology in the Eyes of Henry Adams - Essay Example Firstly, it will contextualize the historical developments that led to the zenith of American development. Secondly, it will discuss the monumental feats at the early years of the Gilded Age and the important industries and figure heads during that time. The Post-Civil War, the Reconstruction Period and President Grant Important developments in the American nation happened notably during the Presidency of Ulysses Grant in 1869, after the Civil War and the offset of the Reconstruction Era. The societal context of Adams’ life at that time was in a period of aggressive American territorial expansion to the West. By traversing the annals of American history during the post-Civil War and the height of the Reconstruction, the politics of the American federal government dictated the type of society that the nation had produced during those years. President Jackson was a hostile leader but more importantly, supportive of the idea of Southern reconstruction. He was willing to give the black race, formerly slaves of the white people, the equality and freedom they were demanding before and during the Civil War. Policies such as the Human Rights of 1865, the establishment of the Freedman’s Bureau and the emancipation of slaves with the eventual abolishment of the policy of slavery was the major political aura surrounding Adams during the 1850s and the 1860s.1 This meant that the society of Adams allowed the osmosis of both races - the whites and the clacks. Parallel with the developments in the political sphere of the United States, accompanying technological advancements had been enhanced at the entrance of President Grant’s administration. This was made possible through the seizure of the Southern plantations under the supervision of the American federal government. In this case, the predominant industrial states up North worked in hand with the agricultural aggregates of the South.2 The formerly debating economies of the North and the South had been complementing one another towards a definite linear development of what would turn out to be a strong American economy. Adams writes in his recollections that the United States at the late 19th century and the dawn of the early 20th century had been fully industrialized. Scientific and technological advancements were the turning points of the time.3 The rise of big businesses and the industrialization of the agricultural sector served the economy well. The United States had almost been immediately marked as one of the rising superpowers of the international scene.4 By analysing what Adams had written, it can be said that based on his words, a rich capitalist-oriented society was at its peak. By his experiences after the Civil War and with the subjugation of the South by the North, political stability went in favor for the Republican Party. In such case, Republican policies and the support of free labor was the basis of American economy.5 The Gilded Age and the Emergence of the Amer ican Oligarchy Adams’ recollection in the chapters â€Å"The Dynamo and the Virgin†, â€Å"The Height of Knowledge† and â€Å"The Grammar of Science†, the author infers the development of America with the entrance of the Gilded Age of politics and economy. Adams greatly details the happenings which surround

Methods - Research Paper Example Results. The control group shows a post-experimental phase mean score of 23.27 with a variance of a little over 12. The experimental group demonstrated a mean score of 16.53 and a variance of almost 17. In terms of the data, the experimental group shows significant improvement in the reduction of bulimic behavior with a seven point reduction in the mean group score over the baseline. The distribution is higher within the experimental group, likely because of the variable efficacy of psychotherapy on individuals. A review of the raw data shows that only four individuals in the group had scores approaching the group's baseline, while others showed dramatic improvement. This effect would not be expected in the control group, and would contribute to a wider distribution around the mean group score. ..

Potency of Selected Plants Essay Example for Free

Potency of Selected Plants Essay Every year, the World Health Organization (WHO) estimates that 50-100 million people all over the world fall victim to dengue fever. And every year, 20,000 of these victims end up dead (the Philippine Star, 2012). According to the report of the Philippine Association of Entomologists (PAE), the incidence and threat of dengue continue to rise, year after year. (Samaniego, 2012). This deadly disease is just caused by a single bite of a carrying mosquito. The mosquito is a common flying insect that is found around the world. The mosquito is often a carrier of diseases, such as malaria, encephalitis, yellow fever, dengue fever, dog heartworm, West Nile virus, and many others. The females, who drink blood, can carry disease from one animal to another as they feed. The mosquito goes through four separate and distinct stages of its life cycle and they are as follows: Egg, Larva, pupa, and adult. It has been found out by studies that buyo, lime and papaya has potential properties that can terminate mosquito larvae. This study entitled ‘Buyo (Piper betle L.), Lime (Citrus aurantifolia), and Papaya (Carica papaya L.) Leaves Powder against Mosquito Larvae ’ aims to investigate the effectiveness of the three leaves powder on the idea of destroying first the source of the problem by terminating first the larvae. Objective of the Study This study, aims to determine the capability of the three plants’ leaves namely: Buyo, Lime and Papaya as a terminating agent, specifically it aims to: 1.Determine the efficacy of the three plant’s leaves against mosquito larvae in the form of powder. 2.Determine if there is a significant difference between the effects of the treatments towards the mosquito larvae. Statement of the Problem This study aims to determine the efficacy Buyo, Lime and Papaya in terminating mosquito larvae. Specifically, it seeks to answer the following questions: 1.Can the three plants serve as a newfound terminating agent for mosquito larvae? 2.Is there any significant difference between them experimental and control set-ups? 3.Is there any further effect on the final treatment on the test organisms? Statement of Hypothesis Based on the foregoing problems, the researchers formulated the following null hypothesis: 1.The three plants cannot serve as a newfound terminating agent for mosquito larvae. 2.There are no significant difference between the experimental and control set-ups. 3.There are no further effects on the final treatment on the test organisms. Statement of the Hypothesis The researchers infer that: 1.The three plants can serve as a newfound terminating agent for mosquito larvae. 2.There is a significant difference between the experimental and control set-ups. 3.There is a further effect on the final treatment on the test organisms. Significance of the Study According to the report of the Philippine Association of Entomologists (PAE), the incidence and threat of dengue continue to rise, year after year. (Samaniego, 2012). The number of deaths from the dengue virus also rose to 328, which is higher than the 293 cases recorded during the same period last year. This deadly disease is just caused by a single bite of a carrying mosquito. This study aims to prevent destroying first the source of the problem by terminating first the larvae without triggering bad side effects. The study may further serve as the baseline information about the worth of the selected plants. Scope and Limitation of the Study This study, ‘Buyo, Lime, and Papaya Leaves Powder against Mosquito Larvae,’ focuses on the potential properties of the three plants towards mosquito larvae in different set-ups. This study limits and focuses only to the topics related to this project. Conceptual Framework Definition of key terms Buyo – is a vine-like plant that can reach 150 to 180 centimeters in height. It is usually used for medicinal uses. Lime – leaves have broadly ovate blades, blunt-pointed at both ends, 3.5-6 cm long, 2.7-4 cm wide with petioles 3,5 to 6 cm long, broadly winged, up to 4 cm wide; wing area sometimes exceeding leaf area. Papaya – is a large, tree-like plant, with a single stem growing from 5 to 10 m (16 to 33 ft) tall, with spirally arranged leaves confined to the top of the trunk. Dengue – Review on the Related Literature Buyo (Piper betle L.), Lime (Citrus aurantifolia), and Papaya (Carica papaya L.) Leaves Powder against Mosquito Larvae Mosquito The mosquito is a common flying insect that is found around the world. There are about 2,700 species of mosquitoes. Mosquitoes can fly about 1 to 1.5 miles per hour (1.6-2.4 kph). Mosquito Bites: Females drink blood and the nectar of plants; the males only sip plant nectar. When a female bites, she also injects an anticoagulant (anti-clotting chemical) into the prey to keep the victims blood flowing. She finds her victims by sight and smell, and also by detecting their warmth. Not all mosquito species bite humans. Disease Carrier: The mosquito is often a carrier of diseases, such as malaria, encephalitis, yellow fever, dengue fever, dog heartworm, West Nile virus, and many others. The females, who drink blood, can carry disease from one animal to another as they feed. Anatomy: Like all insects, the mosquito has a body divided into three parts (head, thorax, and abdomen), a hard exoskeleton, and six long, jointed legs. Mosquitoes also have a pair of veined wings. They have a straw-lik e proboscis and can only eat liquids. Life Cycle: The complete life-cycle of a mosquito takes about a month. After drinking blood, adult females lay a raft of 40 to 400 tiny white eggs in standing water or very slow-moving water. Within a week, the eggs hatch into larvae (sometimes called wrigglers) that breathe air through tubes which they poke above the surface of the water. Larvae eat bits of floating organic matter and each other. Larvae molt four times as they grow; after the fourth molt, they are called pupae (also called tumblers). Pupae alsolive near the surface of the water, breathing through two horn-like tubes (called siphons) on their back. Pupae do not eat. An adult emerges from a pupa when the skin splits after a few days. The adult lives for only a few weeks. Lime The Small-flowered papeda (Biasong) stands out from all others of the subgenus Papeda because of its very small flowers, only 1.2-1.3 cm wide, white, with a trace of purple on the outside. The fruits are 5-7 cm long; surface fairly smooth or with transverse corrugations, lemon yellow; skin comparatively thick; pulp rather juicy, grayish, acid; aroma similar to that of samuyao; Seeds are numerous. The leaves have broadly ovate blades, blunt-pointed at both ends, 3.5-6 cm long, 2.7-4 cm wide with petioles 3,5 to 6 cm long, broadly winged, up to 4 cm wide; wing area sometimes exceeding leaf area. Seeds are numerous. The tree attains a height of 7.5 to 9 meters, with comparatively small but sharp spines. This species is cultivated in the southern Philippine Islands, especially Mindanao, where it is called biasong. The fruit was generally thought of as being inedible, but Ponchit Enrile from the Aseya Bistro in Davao City told me that it is a favourite flavouring for kinilaw (raw fish or seafood marinated with vinegar and limes) and Tom Yum Kung. The fruit can be bought in wet markets all over Mindanao and fetches high prices when not in season. When in season it would sell for 10 US cents a piece. Papaya The papaya is a large, tree-like plant, with a single stem growing from 5 to 10 m (16 to 33 ft) tall, with spirally arranged leaves confined to the top of the trunk. The lower trunk is conspicuously scarred where leaves and fruit were borne. The leaves are large, 50–70 cm (20–28 in) in diameter, deeply palmately lobed, with seven lobes. Unusually for such large plants, the trees are dioecious. The tree is usually unbranched, unless lopped. The flowers are similar in shape to the flowers of the Plumeria, but are much smaller and wax-like. They appear on the axils of the leaves, maturing into large fruit 15–45 cm (5.9–18 in) long and 10–30 cm (3.9–12 in) in diameter. The fruit is ripe when it feels soft (as soft as a ripe avocado or a bit softer) and its skin has attained an amber to orange hue. Carica papaya was the first transgenic fruit tree to have its genome deciphered. Buyo The betel leaf is cultivated in most of South and Southeast Asia. Since it is a creeper, it needs a compatible tree or a long pole for support. Betel requires high land and especially fertile soil. Waterlogged, saline and alkali soils are unsuitable for its cultivation. In Bangladesh, farmers called barui[3] prepare a garden called a barouj in which to grow betel. The barouj is fenced with bamboo sticks and coconut leaves. The soil is plowed into furrows of 10 to 15 metres length, 75 centimetres in width and 75 centimetres depth. Oil cakes, manure, and leaves are thoroughly incorporated with the topsoil of the furrows and wood ash. The creeper cuttings are planted at the beginning of the monsoon season. Proper shade and irrigation are essential for the successful cultivation of this crop. Betel needs constantly moist soil, but there should not be excessive moisture. Irrigation is frequent and light, and standing water should not remain for more than half an hour. Dried leaves and wood ash are applied to the furrows at fortnightly intervals and cow dung slurry is sprinkled. Application of different kinds of leaves at monthly intervals is believed advantageous for the growth of the betel. In 3 to 6 months the vines reach 150 to 180 centimeters in height and they will branch. Harvest begins, with the farmer plucking the leaf and its petiole with his right thumb. The harvest lasts 15 days to one month. The harvested leaves are consumed locally or exported to other parts of Asia, the Middle East, Europe, and the United States. Betel is an important part of the economy in rural Bangladesh.
