Green Sheet 3 Cells the Living Units Essay Green Sheet 3 Cells the Living Units Essay Cells: The Living Units Cellular Basis of Life 1. A cell is the basic structural and functional unit of living organisms. They range from single-celled â€Å"generalists†, like amoebas, to complex multi-cellular organisms such as humans. 2. The majority of cells consist of the same general parts. A generalized cell consists of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm. The membrane separates a cell from its surroundings and decides what comes in or out of the cell. The nucleus determines a cell’s basic function and structure. The cytoplasm, which separates the nucleus and membrane, holds organelles which perform certain tasks for the benefit of the cell as a whole. The Plasma Membrane: Structure 3. The fluid mosaic model of a membrane is structured in a way that allows the diffusion of proteins and lipids. 4. The plasma membrane is made up of two layers of phospholipids. The membrane has many proteins embedded within it, which allow the passage of certain things into and out-of the cell. The hydrophilic (water loving) heads of phospholipids are on the surfaces of the membrane with their hydrophobic (water fearing) tails stay sheathed within. The Plasma Membrane: Functions 5. In passive transport a membrane is permeated by carriers, channels, or direct diffusion. Secondary active transport requires ATP, the cell’s energy, to perform tasks such as the sodium-potassium pump. 6. Simple diffusion is the act of substances passing through a membrane without the aid of an agent, like the embedded membrane protein, to drive it though. Facilitated diffusion occurs only with the aid of proteins. Osmosis is the movement of solvent molecules through a selectively permeable membrane into a higher solute concentration. During filtration, solid particles are separated from the fluid which they are suspended in through a porous membrane. 7. Primary active transport uses direct energy to transport molecules across a membrane. An example of this type of direct activity is the sodium-potassium pump. In contrast to primary active transport, secondary active transport does not directly use ATP, and instead the cell pumps out ions 8. Ve sicular transport is an active process in which materials move into or out of the cell enclosed as vesicles. There are two basic types of vesicular transport: endocytosis and exocytosis. Endocytosis involves the cell bringing materials into itself by enveloping them. Exocytosis involves the cell sending out materials. 9. Membrane potential is created the difference in electric potential between the interior and exterior of a cell. This difference is created by the concentration of extracellular sodium and intracellular potassium. It is maintained by the sodium-potassium pump which pumps out excess potassium. 10. Cell adhesion molecules are proteins located on the cell surface with the purpose to bind to other cells. Cell receptors are composed of two or more protein subunits, which take part in communicating between the cell and the outside world. The Cytoplasm 11. The cytoplasm is the fluid substance within the cell membrane that contains the cell’s organelles except for the nucleus. Organelles have specific functions. Some major organelles are the mitochondria, Endoplasmic Reticulum, Golgi apparatus, lysosomes, and chloroplasts. 12. Certain cells have more of a certain type of organelle than the average cell. This is due to the conditions said cell may undergo. For example, cells of the liver, which detoxifies drugs, have higher amounts of peroxisomes. The Nucleus 13. The nucleus contains a cell’s genetic material in the form of DNA. Its function is to maintain these genes and control the cell’s activities. The nuclear envelope completely encloses the nucleus and separates the cell’s genetic material from the surrounding cytoplasm. The nucleolus of a cell

Case study of the Image Cafe

Case study of the Image Cafe Image Cafà © was founded by Clarence Wooten in 1998. Prior to that he was also a founded of Envision Designs while he was an undergraduate in 1991 and Metamorphosis Studios in 1994 with co-founder Andre Forde. However, the three company did not really last long. In 1998, Metamorphosis Studios had sold to Medisolv, Inc and Image Cafà © was acquired by Network Solution after sever months of market launch (Clarence Wooten, Jr., 2005). About Clarence Wooten, Jr. Clarence Wooten had a big dream since childhood. His dream is to get rich someday. His childhood hobby was playing with computer games. He was so obsessed with computer that his parents banned him at the age of 14 (Kathryn F, Spinelli, 2004: 33-40). At the age of 18, he attended college to study architecture in Catonsville Community College. During that time he believes that by taking up architecture courses can satisfy his creative instincts. In the early 1990s, many professional architects went back to school to upgrade them selves due to the recession. At that point of time, he manages to learn from the senior architects. After the first two failure of his business, he realised that he did not really understand anything about finance after he read the stories from Fred Smith, Reginald Lewis and Bill Gates. This had inspired him to upgrade himself with a business administration and finance. In 1998, he was graduated with B.S. in Business Administration from Johns Hopkins University (Kathryn F, Spinelli, 2004: 33-40). Clarence Wooten, Jr. Venture Spirit Clarence Wooten started Envision Design which was his first business while he enrolled for Catonsville Community College. The type of service he was offering was using form and cardboard to model out a proposed building. The company did not perform well during that time and eventually closed down (Kathryn F, Spinelli, 2004: 33-40). In 1994, Clarence Wooten started his second company Metamorphosis Studios with his co-founded Andre Forde by focusing on spec ial effects and multimedia presentations. Their first customer is Bingwa, an educational software company. However, Bingwa require Metamorphosis Studios to relocate to Princeton, New Jersey and worked for Bingwa. After a thought Clarence Wooten and Andre Forde turned down the offer as they know they are heading for something big (Kathryn F, Spinelli, 2004: 33-40). Metamorphosis Studios was not a successful project too, in 1998 Metamorphosis Studios was acquired by MediSolv, Inc (Clarence Wooten, Jr., 2005). In early 1998, Clarence Wooten started his third company Image Cafà ©. Back in 1995, internet service began to grow. Many companies had started to create their own companies website in order to promote their products and services over the World Wide Web. However, during that time, many companies do not have their own expertise to create a website. Clarence Wooten knew that this is an opportunity and started Image Cafà © to help companies by design their website to promote their products and services over the web (Kathryn F, Spinelli, 2004: 33-40). At the start of Image Cafà ©, Clarence Wooten went around to search for capital in order to start his business. What Clarence Wooten wants was $300,000 capital based on $3 million valuation. In total he received $110,000 from 10 different investors. Image Cafà © website was ready to launch after four month of preparation. However, at that point of time, Clarence Wooten had utilised the cash during the launch. He went back to the existing investors to ask for additional $150,000 in form of bridge loan. This time, Clarence Wooten expects to raise $3million at $10 million valuation (Kathryn F, Spinelli, 2004: 33-40).

Management of medical equipment Essay Example | Topics and Well Written Essays - 2250 words - 1

Management of medical equipment - Essay Example The acquisition subcycle is further subdivided into the following phases: technology assessment, technology planning, acquisition, acceptance, and finally replacement and disposal (Chan, 2003). Technology assessment includes the assessment of the technology or in this case the equipment, mostly in relation to its safety and performance, as well as its projected effect in terms of patient outcomes and its impact on the economic and ethical elements of healthcare (Vallejo-Torres, et.al., 2008). Medical technology and equipment are evaluated in general terms and in relation to other technologies, procedures and interventions. The goal of medical technology assessment is to ensure objective as well as quality data which can be used by stakeholders in their decision-making (Vallejo-Torres, et.al., 2008). The general application of the technology assessment is on the assessment of technologies and equipment after they are introduced in the marketplace. Other experts and researchers however are also quick to point out that new technologies must be assessed before they are incorporated into the clinical practice (Pietzsch and Pate-Cornell, 2008). By evaluating the technology and equipment in the soonest possible time, it is possible to improve health outcomes, reduce wrong investments, and prevent possible ethical issues arising from these technologies (Pietzsch and Pate-Cornell, 2008). Technology planning is the next phase in the acquisition subcycle (Dyro, 2004). This planning phase includes an interdisciplinary planning process alongside years of experience in hospital management and construction, ensuring the establishment of functional procedures within the clinical practice (Hospital Technology, 2012). Planning medical technology...Medical technology and equipment are evaluated in general terms and in relation to other technologies, procedures and interventions. Planning medical technology also includes the acquisition of large-scale medical equipment including M RI, CT, PET-CT, and angiographies among others (Hospital Technology, 2012). The acquisition of the technology includes the actual purchase of the equipment itself. The last phase of the acquisition process is the replacement and disposal of the medical equipment. Unreliable equipment is also usually replaced. Where medical equipment is deemed unserviceable, it is also the responsibility of equipment services managers to indicate to the concerned department managers about the need for equipment replacement. Utilisation subcycle The other phase in the medical equipment lifecycle is the utilisation subcycle. Quality assurance is carried out in order to identify defective medical equipment (David, 2003). Utilisation subcycle and clinical governance Where the users of the equipment are properly trained, the risk to the patient and the medical staff is reduced. The training in equipment use would also include how the users can maintain the equipment, and this process usually includes the daily cleaning and maintenance of the equipment (Pardeshi, 2005). Quality assurance processes often involves routine maintenance and routine equipment check by the technicians as well as independent quality assurance agencies (WHO, 2013). Medical equipment management is an important aspect of the efficient delivery of healthcare services.

2 to 3 page Bible College Administrative Report to be done in APA Essay

2 to 3 page Bible College Administrative Report to be done in APA Format - Essay Example Although established only in 1992, it has a combined instructional history of 130 years (Rocky Mountain College, 2009a, p. 5). RMC offers 2 one-year certificates on Christian Discipleship, 3 two-year diplomas (Christian Leadership, Global Studies & Theatre Arts), a three-year degree on Religious Studies, and 4 four-year degree programs on Human Services, Leadership Development, Music & Theology (Rocky Mountain College, 2009a, p. 22). Founded in 1992 through the cooperation of Lithuanian, Canadian and American foundations, LCC is based in Klaipeda, Lithuania. Its aim is to produce Christian professionals who will actively participate in community projects (LCC, 2009a). LCC offers four undergraduate courses (Business Administration, English Language and Literature, Psychology and Theology) and a Master’s degree in Teaching English to Speakers of Other Languages (TESOL) (LCC, 2009c). Although LCC operates in several countries as a nonprofit organization, it is generally governed by an independent Board of Directors, which is composed of members from North America and Lithuania (LCC, 2009b). It can be seen through the chart above how bible colleges, depending on their size and the breadth of the courses they offer, differ when it comes to governance and organizational structure. While their similarities are obvious, their differences are indistinct and needs a closer look. It must be noted, however, that the exact nature of two out of the three Christian Colleges studied here do not present complete data regarding the hierarchy of power and accountability. Thus, this comparative analysis is based on the available data and the inferences that can be drawn from them. Liberty University is governed primarily by the Chancellor and the President of the Board of Trustees, which is the same person. He is also the son of the founder and the President of the Board of Trustees Committees. Even though managing this large

The First Woman President Of The United States Essay -- essays researc

Senator Hillary Rodham Clinton vs. Condoleeza Rice   Ã‚  Ã‚  Ã‚  Ã‚  I believe that Senator Hillary Rodham Clinton has the better chance of becoming the first woman president of the United States. She is a former First Lady and has had input in the decisions of the Clinton Administration. She worked hand in hand with former President Bill Clinton. She is very smart, a firm believer in her causes such as, helping everyday people, the underprivileged and minorities, etc. Hillary is very outspoken and her voice is heard. She has always believed in advancing the cause civil rights. (Listening to the Media) Hillary Clinton became a resident of New York and ran for and won a seat in the Senate in November 2000. She is the first First Lady elected to the United States Senate and the first woman elected statewide in New York. Her strong negatives were up to 46 percent during her race for senator and she won. Now because of her performance in office, her negatives are down in the mid-30’s. Another supporting factor is that she has run for public office and the people elected her. (Article in, The Washington Times) She is very popular and liked. For the first six years of former President Bill Clinton’s eight years in office she was first on the top ten’s list of most admired women. Her active role began in 1993 when the President asked her to chair the Task Force on National Health Care Reform. She continued to be lead and be the supporter for expandi...

J.J Thomson Essay

J also had a brother that was two years younger than him-self named, Frederick Vernon Thompson. He went to private schools in the beginning of his education career, where he showed a great interest and passion for science, and when was 14 years old when he was accepted in to Owens College. His mother and father originally wanted him to study to be an engineer and get an apprentice for a local locomotive manufacturer, but due to his father’s death in 1873 his plans changed. He moved away from Owens College, and into Trinity College in Cambridge, where he then obtained his BA in mathematics in 1880. He married one of his students, Rose Elizabeth Paget, and they had one son and one daughter. J. J Thompson died still working on the college campus on August 30th, 1940 from unspecified causes at the age of 83. He married one of his students, Rose Elizabeth Paget, and they had one son and one daughter. J. J Thomson was without a doubt religious. He was a devout Anglican Episcopalian who regularly attended services at the Angelican church, and also went to Sunday evening college chapel services. I believe, that the best statement that I found, about the religious practices of Mr. Thomson was from one of his students, Sir Owen Richardson who said â€Å"He was sincerely religious, a churchman with a dislike for Anglo-Catholicism, a regular communicant, who every day knelt in private prayer, a habit known only to Lady Thomson until near the end of his life. Further research shows that J. J Thompson never missed a day of prayer(as quoted above) and that every day before going to sleep, he would read his bible. Some of J. J’s speeches, and addresses also show that he was a devout believer in God, show in what he stated in his inaugural presidential address into the British association, â€Å"As we conquer peak after peak we see in front of us regions full of interest and beauty, but we do not see ur goal, we do not see the horizon; in the distance tower still higher peaks, which will yield to those who ascend them still wider prospects, and deepen the feeling, the truth of which is emphasized by every advance in science, that ‘Great are the Works of the Lord’. † Here we clearly see, that he doesn’t take credit for his accomplishments, he gives the credit to the Lord.

Matrimonium Types of Roman Marriage

Living together, prenuptial agreements, divorce, religious wedding ceremonies, and legal commitments all had a place in ancient Rome. The Romans were unlike other Mediterranean people in that they made marriage a union between social equals instead of valuing submissiveness in women. Motives for Marriage In ancient Rome, if you planned to run for office, you could increase your chances of winning by creating a political alliance through the marriage of your children. Parents arranged marriages to produce descendants to tend the ancestral spirits. The name matrimonium with its root mater (mother) shows the principle objective of the institution, namely the creation of children. Marriage could also improve social status and wealth. Some Romans even married for love, an uncommon thing for the historical time period! The Legal Status of Marriage Marriage was not a state affair—at least it wasnt until Augustus made it his business. Before that the rite was a private matter discussed only between husband and wife and their families. Nonetheless, there were legal requirements so it wasnt just automatic. People getting married had to have the right to marry, or the connubium. Connubium is defined by Ulpian (Frag. v.3) to be uxoris jure ducendae facultas, or the faculty by which a man may make a woman his lawful wife. -Matrimonium Who Had the Right to Marry? Generally, all Roman citizens and some non-citizen Latins had connubium. However, there was no connubium between patricians and plebeians until the Lex Canuleia (445 B.C.). The consent of both patres familias (patriarchs) was required. Bride and groom must have reached puberty. Over time, examination to determine puberty gave way to standardization at age 12 for girls and 14 for boys. Eunuchs, who would never reach puberty, were not permitted to marry. Monogamy was the rule, so an existing marriage precluded connubium as did certain blood and legal relationships. The Betrothal, Dowry, and Engagement Rings Engagements and engagement parties were optional, but if an engagement were made and then backed out of, breach of contract would have had financial consequences. The brides family would give the engagement party and formal betrothal (sponsalia) between the groom and the bride-to-be (who was now sponsa). Dowry, to be paid after the marriage, was decided on. The groom might give his fiancà © an iron ring (anulus pronubis) or some money (arra). How Roman Matrimonium Differed from Modern Western Marriage Its in terms of property ownership that Roman marriage sounds most unfamiliar. Communal property was not part of marriage, and the children were their fathers. If a wife died, the husband was entitled to keep one fifth of her dowry for each child, but the rest would be returned to her family. A wife was treated as a daughter of the pater familias to whom she belonged, whether that was her father or the family into which she married. Distinctions Between Marriage Types Who had control of the bride depended on the type of marriage. A marriage in manum conferred the bride on the grooms family along with all her property. One not in manum meant the bride was still under the control of her pater familias. She was required to be faithful to her husband as long as she cohabited with him, however, or face divorce. Laws regarding dowry were probably created to deal with such marriages. A marriage ​in manum made her the equivalent of a daughter (filiae loco) in her husbands household. There were three types of marriages in manum: Confarreatio - Confarreatio was an elaborate religious ceremony with ten witnesses, the flamen dialis (himself married confarreatio), and pontifex maximus in attendance. Only the children of parents married confarreatio were eligible. The grain far was baked into a special wedding cake (farreum) for the occasion, hence the name confarreatio.Coemptio - In coemptio, the wife carried a dowry into the marriage, but was ceremoniously bought by her husband in front of at least five witnesses. She and her possessions then belonged to her husband. This was the type of marriage in which, according to Cicero, it is thought the wife declared ubi tu gaius, ego gaia, usually thought to mean where you [are] Gaius, I [am] Gaia, although gaius and gaia need not be praenomina or nomina*.Usus - After a years cohabitation, the woman came under her husbands manum, unless she stayed away for three nights (trinoctium abesse). Since she wasnt living with her paterfamilias, and since she wasnt under the han d of her husband, she acquired some freedom. Sine manu (not in manum) marriages, wherein a bride stayed within the legal control of her natal family, began in the third century B.C. and became the most popular by the first century A.D. In this popular model, the woman could own property and manage her own affairs if her father died. There was also a marital arrangement for slaves (contuberium) and between freedmen and slaves (concubinatus). Resource: *Ubi tu gaius, ego gaia.
