Stem Cell Research is Bad Stem Cell Research is Bad and Should Not Be Done Stem cell research is conducted in order to obtain advanced knowledge on how an organism will develop from one cell and how healthy cells can be used to replace damaged cells in an adult. Stem cell research has paved the way for scientists to conduct investigations on the likelihood of cell-based therapies in the treatment of diseases, which is often called regenerative or reparative medicine (National Institutes of Health [NIH] 2).

Stem Cell Research Concepts, Issues, And Origin Before explaining the negative implications of stem cell research, it is important to understand first the concepts and issues involved in this field of study as well as its origin. First of all, there are two important attributes of stem cells that set them apart from other kinds of cells. First, they have the capacity to rejuvenate themselves for extended periods through the process of cell pision because of their nature as unspecialized cells. Second, by placing them under certain physiologic or experimental circumstances, stem cells can be transformed to become cells with specialized functions such as the beating of the heart muscle or producing insulin for the pancreas (NIH 2). Generally, scientists utilize two types of stem cells from animals and humans: embryonic and adult stem cells, which have varying functions and qualities. There are various reasons why stem cells are deemed important to human beings. In a blastocyst (a 3-5 day old embryo), for example, they are helpful in the development of several specialized kinds of cells that constitute the heart, skin, lung, and other tissues. In the tissues of some adults, stem cells help in the generation of replacements for cells that are damaged because of wear and tear, injury, or diseases (NIH 3). During the latter portion of the 1990s, scientists found out many attributes of stem cells. According to investigations, even the mature stem cell from a single tissue is enough to produce cells of another tissue variety, such as neurons for the brain. A research conducted by Fred Gage at the Salks Institute for Biological Studies shows that the brains of human adults can produce new neurons. Prior to Gages findings, scientists assumed that the human brain does not have the capacity to produce new cells after birth (Stem Cell). In 1981, the first cultures of stem cells were cultivated by scientists from mice embryos. Although the experiment spearheaded extensive research, developing human stem cells remained an elusive goal until 1998 (American Association for the Advancement of Science [AAAS]). Nevertheless, it was on November 1998 that the isolation of human embryonic stem cells (hESCs) was first discovered by Dr. James Thomson, a biologist at the University of Wisconsin. hESCs can be used in the differentiation of any kind of human cell, which can range from blood to skin cells. For scientists, they were aiming to utilize them in repairing damaged tissues (AAAS). However, the work of Dr. Thomson was not qualified for funding from the National Institutes of Health (NIH) because of an existing ban on human embryo research. Congress placed a prohibition for funding on such kind of research. The bill, authored by Rep. Jay Dickey, disallowed funding for research on hESCs until 2001 (AAAS). Due to the great promise of Dr. Thomsons findings, the NIH sought legal help from the Department of Health and Human Services (HHS) concerning the ban to hESC. In 1999, the HHS reached the conclusion that public funds can be used on hESC on the premise that derivation of the cells would be conducted with private funds (AAAS). On August 9, 2001, President George W. Bush granted Federal funding on hESC research on the condition that the cells that will be used will be those that currently exist. President Bush allowed funding for such because the destruction of an embryo had already occurred. He did not permit the disbursement of public funds on future cell lines in order that they would not act in such a way that it would promote the destruction of human embryos (AAAS). On May 24, 2005, the United States House of Representative passed House Resolution 810 entitled Stem Cell Research Enhancement Act by a vote of 238 in favor of the bill against 194 opposing the bill. Ninety three percent of Democrats supported the bill while 79% rejected the bill (White, Text of H.R. 810). Two days later on May 26, 2005, the Senate voted 63 to 37. However, President George W. Bush vetoed it on July 2006 based on ideological and religious grounds. If the Stem Cell Research Enactment Act had been approved by Bush, it would have provided Federal funding for the conduct of stem cell research. However, in other countries, such as South Korea, Great Britain, Germany, Japan, and India, stem cell research is already being conducted (White, Text of H.R. 810). Arguments Against Stem Cell Research The issue of stem cell research has been met with both support and criticism. Here are some of the arguments against stem cell research: Human Life Begins at Conception. One of the basic arguments is the fact that an embryo is already considered a human being because during fertilization, an egg has the potential of becoming a full-grown adult. This is in compliance with the assertion that human life begins during conception. Another issue in question when it comes to this argument is viability, which is defined as the ability of a fetus to potentially live outside the womb of the mother, albeit with artificial assistance (GE Team). Instead of pursuing embryonic stem cell research, alternatives should be considered. Research conducted by pro-life supporters claims that using adult stem cell for research is more promising instead of the embryonic stem cells. Critics of using embryonic stem cell research argued that it has no practical treatment (GE Team). Scientific errors in conducting an embryonic stem cell research Utilizing embryonic stem cell in therapies may contain fundamental flaws. For example, it was determined in one study that embryonic stem cells applied to therapeutic cloning may still be prone to immune rejection. On the other hand, there have been indications that adult stem cells can be successfully reintegrated into an autogenic animal. Likewise, embryonic stem cells have the tendency to create tumors (GE Team). Exaggeration Of Research Potential Scientists have vowed promising results from using embryonic stem cell research, and so far, this has not yet happened. In fact, majority of the criticisms have been made by the researchers themselves. The past president of the British Association for the Advancement of Science Lord Winston has even issued a warning that there is a potential backlash against stem cell research (GE Team). Even the late Pope John Paul II was very much against embryonic stem cell research. According to the late Pontiff, man must learn from previous experience which showed the negative effects of destruction of human life through acts such as euthanasia and infanticide (The Cases For and Against Stem Cell Research). In addition, many ethicists and scientists are likewise against embryonic stem cell research. In a statement issued on July 1999, a group composed of bioethicists, legal scholars, and scientists stated their objection against stem cell research because they were against human ethics and is unnecessary (The Cases For and Against Stem Cell Research). Another major argument by opponents of stem cell research is that there has been little attention given to adult stem research which has proven successful in the treatment of various diseases. Likewise, the opponents of embryonic stem cell research claims that therapeutic approach using stem cells have no proven cure yet (White, Pros ). Likewise, opponents of the stem cell research have instead pushed for funding adult stem cell research in order to get around the moral issues surrounding the use of human embryos (White, Pros ). Conclusion Stem cell research is a method of using human embryos in producing new cells as well as in replacing damaged cells. The method was discovered in 1998 by Dr. James Thompson. However, he could not proceed further because such kind of undertaking was not given Federal funding. One of the main arguments against stem cell research is that using a human embryo for research can destroy the life of the unborn infant already conceived in the fertilized egg. Another negative argument about stem cell research is that it has yet to produce conclusive evidence of being an effective cure. Opponents of stem cell research is instead pushing for an adult stem cell research which has already a proven record of effectivity. House Bill 810 or the Stem Cell Research Enhancement Act was approved in both Houses of Congress but was vetoed by President George Bush for ideological and ethical issues.

Introduction Essays - Food And Drink, Cola, Coca-Cola, Kosher Food

Introduction Essays - Food And Drink, Cola, Coca-Cola, Kosher Food Introduction The company I have chosen for this topic is the Coca-Cola Company. The Coca-Cola Company is the world's largest beverage company, refreshing consumers with more than 500 sparkling and still brands and nearly 3,900 beverage choices. Led by Coca-Cola, one of the world's most valuable and recognizable brands, the company's portfolio features 21 billion-dollar brands, 19 of which are available in reduced-, low- or no-calorie options. These brands include Diet Coke, Coca-Cola Zero, Fanta, Sprite, Dasani, vitamin water, PowerAde, Minute Maid, Simply, Del Valle, Georgia and Gold Peak. Through the world's largest beverage distribution system, they are the No. 1 provider of both sparkling and still beverages. More than 1.9 billion servings of their beverages are enjoyed by consumers in more than 200 countries each day. With an enduring commitment to building sustainable communities, their company is focused on initiatives that reduce their environmental footprint, create a safe, inclusive work environment for their associates, and enhance the economic development of the communities where they operate. Together with their bottling partners, they are ranked among the world's top 10 private employers with more than 700,000 system associates. (The Coca-Cola Company, 2017) Their strategic framework They are drivenby four strategic priorities : Community trust, consumerrelevance, customer preference and cost leadership. Community Trust Coca-Cola believes in building trust within their communities. Trust is the foundation of their relationships with shareholders, customers, consumers, employees, ins titutions and business partners, and they build trust through responsible, sustainable management for their business. Consumer Relevance For Coca Cola, consumer relevance means meeting and exceeding consumer expectations by offering the right products, in the right packs, through the right channels for the right occasion. These products must be consistently fresh, in premium condition, and presented cold when that is appropriate Customer Preference Building successful relationships with their customers is what they believe as their fundamental to success. They work hard to ensure their people are constantly focused on customer needs and satisfaction. They aim to exceed expectations in terms of delivery and execution to be the best supplier, and work as partners in creating value to achieve the best relationship. Cost Leadership Coca-Cola's gross margin improved by 100% in 2015, and their comparable operating margin expanded by the same amount. While lower input costs and adverse foreign exchange movements had the biggest impact on their profits. Their focus remains on the areas that they can influence: optimization of their production and logistics base, their operating costs and cash conversion. (Coca-colahellenic.com, 2017) Operations of Coca-Cola Company Coke manages seven main operating segments (most of them geographically-based), including: Eurasia and Africa Europe Latin America North America Asia Pacific Bottling Investments Corporate. The North America operating segment generates the majority of its revenue from the sale of finished beverages, while the other geographic regions get most of their business from the manufacture and sale of beverage concentrates and syrups The Bottling Investments division focuses on the beverage company's owned bottling operations outside of North America. This segment helps to maximize the efficiency of its production, distribution, and marketing efforts. (Vault, 2017) 952503215005 Figure SEQ Figure \* ARABIC 1 Operations management flow chart in Coca-Cola Figure SEQ Figure \* ARABIC 1 Operations management flow chart in Coca-Cola9525070040500Operations Management Flow Chart in Coca-Cola The operations management flow chart consists of inputs which are the resources needed to produce the outputs, outputs which are the finished goods which comes out of the production line and the transformation process of how the inputs are converted into outputs. Depending on the output of the production, customer feedback can be obtained to know the opinions of customers on the goods provided to them and also performance information can be obtained from the outputs to evaluate the productions performance overall during a time period. In order for operations to take place, there should be inputs such as machinery's present in the organization to carry out its production line efficiently. As Coca-Cola is one of the big brands today in the beverage industry, they must keep updating their machinery in order to minimize risks of failure in the production line. Coca-Cola should also consider itself to adapt to the latest technology trends available compared to the technology which was available when they started their productions back in the days, to compete with

Beryllium Facts - Periodic Table of the Elements

Beryllium Facts - Periodic Table of the Elements Beryllium Atomic Number: 4 Symbol: Be Atomic Weight: 9.012182(3)Reference: IUPAC 2009 Discovery: 1798, Louis-Nicholas Vauquelin (France) Electron Configuration: [He]2s2 Other Names: Glucinium or Glucinum Word Origin: Greek: beryllos, beryl; Greek: glykys, sweet (note that beryllium is toxic) Properties: Beryllium has a melting point of 1287/-5Â °C, boiling point of 2970Â °C, specific gravity of 1.848 (20Â °C), and valence of 2. The metal is steel-gray in color, very light, with one of the highest melting points of the light metals. Its modulus of elasticity is a third higher than that of steel. Beryllium has high thermal conductivity, is nonmagnetic, and resists attack by concentrated nitric acid. Beryllium resists oxidation in air at ordinary temperatures. The metal has a high permeability to x-radiation. When bombarded by alpha particles, it yields neutrons in the ratio of approximately 30 million neutrons per million alpha particles. Beryllium and its compounds are toxic and should not be tasted to verify the metals sweetness. Uses: Precious forms of beryl include aquamarine, morganite, and emerald. Beryllium is used as an alloying agent in producing beryllium copper, which is used for springs, electrical contacts, nonsparking tools, and spot-welding electrodes. It is used in many structural components of the space shuttle and other aerospace craft. Beryllium foil is used in x-ray lithography for making integrated circuits. It is used as a reflector or moderator in nuclear reactions. Beryllium is used in gyroscopes and computer parts. The oxide has a very high melting point and is used in ceramics and nuclear applications. Sources: Beryllium is found in approximately 30 mineral species, including beryl (3BeO Al2O3Â ·6SiO2), bertrandite (4BeOÂ ·2SiO2Â ·H2O), chrysoberyl, and phenacite. The metal may be prepared by reducing beryllium fluoride with magnesium metal. Element Classification: Alkaline-earth Metal Isotopes: Beryllium has ten known isotopes, ranging from Be-5 to Be-14. Be-9 is the only stable isotope.Density (g/cc): 1.848 Specific Gravity (at 20 Â °C): 1.848 Appearance: hard, brittle, steel-gray metal Melting Point: 1287 Â °C Boiling Point: 2471 Â °C Atomic Radius (pm): 112 Atomic Volume (cc/mol): 5.0 Covalent Radius (pm): 90 Ionic Radius: 35 (2e) Specific Heat (20Â °C J/g mol): 1.824 Fusion Heat (kJ/mol): 12.21 Evaporation Heat (kJ/mol): 309 Debye Temperature (K): 1000.00 Pauling Negativity Number: 1.57 First Ionizing Energy (kJ/mol): 898.8 Oxidation States: 2 Lattice Structure:Hexagonal Lattice Constant (Ã…): 2.290 Lattice C/A Ratio: 1.567 CAS Registry Number: 7440-41-7 Beryllium Trivia Beryllium was originally named glyceynum due to the sweet taste of beryllium salts. (glykis is Greek for sweet). The name was changed to beryllium to avoid confusion with other sweet tasting elements and a genus of plants called glucine. Beryllium became the official name of the element in 1957.James Chadwick bombarded beryllium with alpha particles and observed a subatomic particle with no electrical charge, leading to the discovery of the neutron.Pure beryllium was isolated in 1828 by two different chemists independently: German chemist Friederich WÃ ¶hler and French chemist Antoine Bussy.WÃ ¶hler was the chemist who first proposed the name beryllium for the new element.

Any citizen who does not have a criminal record should be permitted to Essay - 1

Any citizen who does not have a criminal record should be permitted to carry a concealed weapon - Essay Example This can occur in the case an official is committing a crime against a citizen. Additionally, there are activists who strongly oppose the whole idea of citizens possessing weapons. The concern however is, should the citizen helplessly watch the officials use their power to mistreat citizens instead of working for them.   Ã‚  Ã‚  Ã‚   While the restrictions against ownership of weapons are still strict, the level of crime is still high. Most of the violent attacks are executed using weapons meaning that the criminals, who are still citizens, possess the weapons though illegally (Cothran 40). The government has not been in a position to completely provide security to the citizen; this is because of the long distance between the security quarter and the scene of the attacks. The security officials find it difficult to respond to a citizen’s security concern in time. As long as the security official takes much time, the criminals tend to have enough time to hurt the victim. The dilemma remains, should the government formulate and enforce more restrictions or should the restrictions be relaxed. The activists against the possession of weapons by citizens still hold strong to their belief (Lovelace 56). They argue that if a person is legalized to shoot in the event of an attack, this reduces the power of the law. The State government is left with no law to enforce. However, in this proposal, a clear explanation is given as to why a person should be allowed to own a weapon so long as he meets the qualifications given. While there is a need to legalize the ownership of the weapon by the citizens, some of the cases presented in court in past, have proved some of the people in possession of weapons use them in committing criminal offences. For instance, a citizen may use the weapon to revenge (Lovelace 39). A law to legalize carrying of weapons by citizens is a

Can it be decided by you - Essay Example However, their strong holds were later to be shaken. As a matter of fact the major political changes in the region occurred from 1809 to 1825. This is according to the historyworld.net website. (historyworld.net, 2009) The royal family of Portugal stayed on in Brazil and a treaty was signed between Portugal and England in 1810 and this overlapped the treaty of Methuen of the year 1703. This recognized a direct accessibility to Brazil by the traders of Britain which made faster the movement towards the political independence of Brazil. (Birmingham, 2003 p99) This study is set out to analyze the Brazilian case of independence movement and make a comparison of this case with other Latin American Spanish colonized states. To this an answer will be provided for the study question, â€Å"How was the Spanish- Latin American countries’ independence movements more violent compared to Brazil?† The Brazilian case of decolonization was not devoid of bloodshed. This is as it is written on the about.com website. Towards the end of year 1821, the Cortà ©s were involved in a voting, with just few Brazilian delegates taking part. The voting led to the abolishment of the kingdom of Brazil as well as the royal Rio de Janeiro agencies. The voting also sought to ensure that all provinces subordinated directly to the city of Lisbon. Subsequently, Portugal drove its army troops to Brazil and also placed all the units of Brazil under the command of Portugal. In the beginning of year 1822, the Brazilians who were born in Portugal and the troops of Portugal had a lot of tension between them. This turned into a violent ordeal when Pedro made an acceptance of Brazilian towns’ petitions who wanted his refusal of the order by Cortà ©s to go back to Lisbon. Following this, Pedro responded to the pressure as well as the fact that if he dismantled the central government and departed it would cause separatist movements, by vowing to

Airport Planning, Operations and Management

Airport Planning, Operations and Management Lakshmi Vadlamoodi In Airport Development planning, what is the importance of an airport master plan, what is its purpose and what are some of the challenges that may be faced in its development? An Airport Master plan is a document which provides an overview of the airport, and discusses the long-term issues using the current existing plan (Ruiz-Celada, 2014). There are many elements that contribute towards airport development which includes environmental factors, land use, government, route development, and many other factors (Ruiz-Celada, 2014). The Purpose of a Master plan is to provide future vision and is used to predict future problems. Master Plan should be thoroughly evaluated every five years or more often if needed (De Groot, 2017). It is also used to depict the range of cost for the airport growth, so that it helpful for planning financially (Skipp, 2006). The Master plan provides the public the need of the airport and the potential uses (Airport Plan, 2016). It also provides details about the development process (or a big picture) of the airport, the precautions taken and the standards maintained (Growth forecasts and developments objectives, 2014). However, there are challenging as well. Some of the major challenges faced when planning includes budgeting for buying new material, which are expensive; constantly upgrading technology trends (Glass Flight Deck); passenger forecasting (uncertainty of passenger capacity); and ultimately the revenue (Stringfellow, 2013). For example, Sydney airports guiding principle is to maximize benefits for the passengers and the aviation community considering the stakeholders as well. Balancing of the activity more evenly throughout the airfield, terminals and roads reduce congestion and improve terminal infrastructure utilisation (De Groot, 2017). Another example is Melbourne Airports Master Plan, which is a Mid-term Development plan. Its concept provides a snapshot of the future passenger traffic which increases to 64 million (Passengers per year) by 2033. The Master Plan also states that the Domestic and the International terminals are being merged soon (De Groot, 2017). Therefore, Melbourne Airport uses its Master Plan to develop their airports revenue. Thus, a Master Plan plays a vital role in Airport Development. Explain the importance of non-aeronautical revenue for airports and the challenges faced by contemporary airports in planning for the future generation of non-aeronautical revenue? Contemporary airports struggle to get profits if they continue to rely on their passengers and airlines for profit, hence airports are diversifying their sources of income through Non-Aeronautical Revenue (Marello, 2015). It is the income of the airport which excludes aeronautical activity such as commercial flying, as this is a dominant source of income which provides profits for the airport business (Non-Aeronautical Revenue, 2013). They are acquired from sources like parking lots, Car rentals, accommodation, retail, food/beverage and duty-free shops on the airport land. They are also increasing the freight and cargo facilities to expand their sources of income (Marello, 2015). Research says that 40% of an average global airports revenue is derived from the Non-Aeronautical Revenue sector (Concessionaire Analyser+, 2016). Increasing pressure on aeronautical revenues have been proved to be beneficial for promoting airports to further develop alternative revenue sources, which results in the increase of the profit margin (Concessionaire Analyser+, 2016). However, the global airports revenue sector will continue to face challenges ranging from pressure on passenger-driven non-aeronautical revenues to a possible oversupply of airport retail space (Lee, 2015). Non-aeronautical sector has therefore turn out to be a key element which influences the airports performance mostly (Non-aeronautical Revenue, 2007). Car parks, Car rentals and accommodation are fast-growing sources of revenue for the airports (De Groot, 2017). A total of 22% of airports car park is contributed towards Non-aeronautical revenue, at Brisbane airport (De Groot, 2017). Airports predict future passenger traffic, and the air traffic for estimating the investment in improving the infrastructure of the airport, as traffic forecasts provide criteria for both facility and financial planning (De Groot, 2017). The influence of Low Cost Carriers (LCCs) has also influenced in increasing attention on Non-aeronautical sector (Assessing the Non-Aviation Performance, 2008). The global airports must aim to attract new target market into the duty-free shops; food and beverage (Lee, 2015).ÂÂ   Also, it must aim to expand the target market further for it to increase the revenue and ultimately, the profit margin. How does the dominance of airport security challenge planning for non-aeronautical revenue generation by contemporary airport management and how can it be better managed in the future? There are possible increased threats in the contemporary times, especially at the airports. It is said that airport security plays an important role in a passengers journey (Lee, 2015). Security is increasing in Aviation to make passengers feel secured and easier for them to travel. The industry is implementing many new methods of security to minimise the risk at an airport and meet the new safety standards made (The challenge for airline security, 2017). Airports are always looking to improve the efficiency of the airport security. When evaluating an airport, some key elements which need to be taken account are the potential threats such as thefts and attacks, environmental protestors such as terrorist attacks which can be harmful for the airport equipment such as the aircraft (Improving airport security effectiveness, 2017). For instance, there was a failed bomb attack in a flight from Amsterdam and was ready to land in Detroit in 2009. It was stated that the suspect was declared in the Not-to-fly category before this flight. The investigators wonder how he was cleared from the airport security at Amsterdam (TheCostaRicaFrog, 2009). Hence why, airport security is a top priority and a challenge for most of the airports (Security and Customs, 2017). The global airports have developed a better security system after that incident. It can also be a challenge because to make airports more safe and secured, the management need to invest more, thus the consequence could result in low profit margin. For improving airport security, there are a list of prohibited items which cannot be taken in the cabin luggage such as harmful substances and sharp objects. If any suspected/restricted objects are detected, then the passengers luggage will be individually verified (Airport security measures, 2017). The Airport security is a big sector for a passenger before they reach the boarding area to embark an aircraft. Furthermore, Passengers who are proceeding to the boarding area must remove all the electronic gadgets from their luggage and scan it through separately (Airport security measures, 2017). Predicting the passenger traffic and future air traffic will also help in planning financially for investing in the airport security. The predictions can be obtained by major airline manufactures. Overall, there are challenges in everything, provided the necessary precautions are taken (De Groot, 2017). References Airport plan Western Sydney Airport. (2016).
