The Influence of the Cold War and the Space Race essays

The Influence of the Cold War and the Space Race essays The Influence of the Cold War and the Space Race On the Evolution of Todays Technology A few hundred key inventions have marked mankinds progress from the Stone Age to the Space Age. What were these inventions? Who made them possible? Where would the world be today if the space race would of not been part of our historical progress? Some people believe that mankind would have been better off left alone. This paper will demonstrate that the space race during the cold war has influenced the course of success of a new era of technology in many aspects improving the material prosperity of mankind. Since the early 1900, economic growth and strength of nations have been directly related to the ability of its people to make discoveries and their ability to transform these discoveries into useful products. A large portion of these discoveries where made during the space race of the cold war and became attributable to technological advancement. From the Abacus, the simplest form of calculating to the role of todays computer, from the early telegraph to todays satellite communi cations, from the simplest kite to todays Jet Engine Airplanes, from the first liquid-fuelled rocket to todays Space Shuttle, and much more to come, inventors, scientist, engineers, military forces and governments have all been responsible for those new discoveries made by mankind. Perhaps the most misleading catch-phrase learned in childhood is that Necessity is the mother of invention creating social compulsions no one knows how to control. (The Inventions, pg.8) In the 1980s, people were embroiled in many problems related to the evolution of technology, from those created by the microchip to those unleashed by the H-bomb. In contrast, invention springs from a divine discontent with things the way they are and a conviction that man can do better. It is a conviction mankind should do their best to c...

The Parts of a Flowering Plant

The Parts of a Flowering Plant Plants are eukaryotic organisms that are characterized by their ability to produce their own food. They are vital to all life on earth as they provide oxygen, shelter, clothing, food, and medicine for other living organisms. Plants are very diverse and include organisms such as mosses, vines, trees, bushes, grasses, and ferns. Plants can be vascular or nonvascular, flowering or nonflowering, and seed-bearing or non-seed bearing. Angiosperms Flowering plants, also called angiosperms, are the most numerous of all the divisions in the Plant Kingdom. The parts of a flowering plant are characterized by two basic systems: a root system and a shoot system. These two systems are connected by vascular tissue that runs from the root through the shoot. The root system enables flowering plants to obtain water and nutrients from the soil. The shoot system allows plants to reproduce and to obtain food through photosynthesis. Root System The roots of a flowering plant are very important. They keep the plant anchored in the ground and obtain nutrients and water from the soil. Roots are also useful for food storage. Nutrients and water are absorbed through tiny root hairs that extend from the root system. Some plants have a primary root, or taproot, with smaller secondary roots extending from the main root. Others have fibrous roots with thin branches extending in various directions. All roots do not originate underground. Some plants have roots that originate above ground from stems or leaves. These roots, called adventitious roots, provide support for the plant and may even give rise to a new plant. Shoot System Flowering plant stems, leaves, and flowers make up the plant shoot system. Plant stems provide support for the plant and allow nutrients and water to travel throughout the plant. Within the stem and throughout the plant are tube-like tissues called xylem and phloem. These tissues carry water, food, and nutrients to all parts of the plant.Leaves are the sites of food production for the flowering plant. It is here that the plant acquires light energy and carbon dioxide for photosynthesis and releases oxygen into the air. Leaves can have various shapes and forms, but they all consist of a blade, veins, and a petiole. The blade is the flat extended part of the leaf. The veins run throughout the blade and provide a transport system for water and nutrients. The petiole is a short stalk that attaches the leaf to the stem.Flowers are responsible for seed development and reproduction. There are four main flower parts in angiosperms: sepals, petals, stamens, and carpels. The stamen is considered the male portion of a plant and the carpel is considered the female port ion. Pollen is produced in the stamen, and the female ovary is contained within the plant carpel. Pollen is transferred from stamen to carpel by plant pollinators such as bugs, birds, and mammals. When the ovule (egg cell) within the ovary becomes fertilized, it develops into a seed. The ovary, which surrounds the seed, becomes the fruit. Flowers that contain both stamens and carpels are called perfect flowers. Flowers that are missing either stamens or carpels are called imperfect flowers. If a flower contains all four main parts (sepals, petals, stamens, and carpels), it is called a complete flower. Sexual Reproduction and Flower Parts Flowers are the sites of sexual reproduction in flowering plants. The stamen is considered the male portion of a plant because it is where sperm is produced and housed within pollen grains. The carpel contains the female reproductive organs. Sepal: This typically green, leaf-like structure protects the budding flower. Collectively, sepals are known as the calyx.Petal: This plant structure is a modified leaf that surrounds the reproductive parts of a flower. Petals are typically colorful and often scented to attract insect pollinators.Stamen: The stamen is the male reproductive part of a flower. It produces pollen and consists of a filament and an anther.Anther: This sac-like structure is located at the tip of the filament and is the site of pollen production.Filament: A filament is a long stalk that connects to and holds up the anther.Carpel: The female reproductive part of a flower is the carpel. It consists of the stigma, style, and ovary.Stigma: The tip of the carpel is the stigma. It is sticky so it can collect pollen.Style: This slender, neck-like portion of the carpel provides a pathway for sperm to the ovary.Ovary: The ovary is located at the base of the carpel and houses the ovules. While flowers are necessary for sexual reproduction, flowering plants can sometimes reproduce asexually without them. Asexual Reproduction Flowering plants can self-propagate through asexual reproduction. This is accomplished through the process of vegetative propagation. Unlike in sexual reproduction, gamete production and fertilization do not occur in vegetative propagation. Instead, a new plant develops from parts of a single mature plant. Reproduction occurs through vegetative plant structures derived from roots, stems, and leaves. Vegetative structures include rhizomes, runners, bulbs, tubers, corms, and buds. Vegetative propagation produces genetically identical plants from a single parent plant. These plants mature faster than and are sturdier than plants that develop from seeds. Summary In summary, angiosperms are differentiated from other plants by their flowers and fruit. Flowering plants are characterized by a root system and a shoot system. The root system absorbs water and nutrients from the soil. The shoot system is composed of the stem, leaves, and flowers. This system allows the plant to obtain food and to reproduce. Both the root system and shoot system work together to enable flowering plants to survive on land.

Researching gender and crime - Essay Example This paper, incidentally will be concerned with evaluating and giving a detailed analysis of the research in two stages: stage one will look into summarizing the entire research work while stage two will be on an evaluation of the research based on the methodology. Research in Criminology is often described as an investigation often conducted on any phenomenon that is linked to any or all existing aspects of the criminal justice system (Dantzker and Hunter, 2012).Therefore, any research that pertains to criminology should bear themes that pertain to criminal acts, the social justice, offenders, legal or illegal actions to mention but a few. In the article, the research was carried out on five male ex-offenders who attempted to give a description of their distinct experiences of life after prison; this in itself already qualifies the research with reference to its appropriateness in Criminology. There is also a need to understand that research in Criminology is often divided into two: applied research and basic research; in this particular research, applied research has been incorporated as it focuses on one particular issue, the ex-offenders’ status and how it impacts self and gives implications of the effects top foster change. To know if at all the research is valid; it is necessary to contextualize how it was conducted in light of how criminological research should be carried out. To begin with, the research problem is clearly defined in terms of what the study intends to look into which are the experiences that the ex-prisoners go through after leaving prison specifically in terms of employment, self-change and identity. Objectives in research are detrimental as they give the researcher a sense of direction; in the study the objective is captured under the purpose of study, which is to understand the experience of

Critique of King's theory of the goal of attainment Research Paper

Critique of King's theory of the goal of attainment - Research Paper Example This extensive work in the nursing field contributed greatly in the theory because of her experience in the nursing field research (King, 2007). The Theory of Goal Attainment describes the relationship between people working together to attain a certain goal. In this case, a patient and a nurse, communicate when working together, to achieve a goal, the patient’s health. The theory looks at interpersonal systems, personal systems and social systems, how human beings use these aspects in their daily life while trying to attain their goals. The theory uses concepts to show how each system works. The concepts are defined in both theoretical and operational terms describing the systems and their application. The concepts for personal system are; growth and development, body image, space, time, self, and perception. The concepts for interpersonal system are; transaction, role, interaction, communication and stress. The social system concepts are; Authority, power, organization and status and decision making (King, 1991). The theory enlists the explicit and implicit assumptions underlying it: the nursing focus, its goal, the goal of nurses, nursing process, plan, implementing and evaluating nursing care. Nurses and patients communicate, set goals mutually, and then work to attain those goals. In life situation, people interact, perceive and enter into situations and in the process, each participant is changed (King, 2007). The theory also describes the four Metaparadigm concepts of nursing, which are: a human being, health, environment and nursing. The theory reflect clarity of thought process in that a human being is rational, perceive, think, feel, choose, set goals, select means to achieve goals and make decisions. The theory explains the logical congruence of the internal structure of the theory by showing how the systems come together and the attainment of goals. The theory does not give an indication that help predict or control

J. R. R. Tolkien :: essays research papers

John Ronald Reuel Tolkien, creator of a world. When someone who knows Tolkien is asked about his works, one thought comes to mind, Middle Earth. This was the playground in his mind that such vivid descriptions of fantasylands came from. It is the base of his most well known stories, where dreams are just the norm. J.R.R. may owe much of his success to his diverse beginnings. On April 16, 1891, Mabel Suffield and Arthur Reuel Tolkien were married in Bloemfontein, South Africa. They soon gave birth to John Ronald Reuel Tolkien on January 3, 1892, who was christened later that month. In April of 1895 Mabel took J.R.R. and his younger brother to Birmingham England. Arthur, their father, was supposed to follow them in a few months, however never does, as he dies shortly before his trip. This causes a struggling early life for John, moving constantly. At age 7 he took the entrance exam for King Edwards School, failed, but gained acceptance a year later and move closer to the school. The Tolkiens move several more times, and end up near the Grammar School of St. Philips, where John’s mother enrolls him to save money. J.R.R. won a scholarship, however, and returned to King Edwards to continue his studies. On September 14, 1904, Mabel Tolkien, John’s mother, dies after a diabetic coma. After the death of his mother, the guardianship of his brother and him was taken over by Father Francis Xavier Morgan, a priest of the Birmingham Oratory. In 1908, J.R.R. started his first term at Oxford, and in 1915 he was awarded First Honours degree in English Language and Literature. The following year, March 22, 1916, John Tolkien married Edith Bratt. Between the years of 1917 and 1929, the couple had four children together, John, Michael, Christopher, and Priscilla. Tolkien’s children had a great impact on his writings. One of the best instances of this is in his book Roverandom. In 1925, while on vacation with his family on the Yorkshire coast, four-year-old Michael Tolkien lost his favorite toy, a little lead dog he was reluctant to put down even to play on the beach. To console and distract him J. R. R. improvised a story, the story of Rover, a real dog magically transformed into a toy. After many fantastic adventures in search of the wizard who wronged him, at last he wins back his doggy life.
