Research in Motion Globalization Paper Example | Topics and Well Written Essays - 500 words

In Motion Globalization - Research Paper Example (Peers ). One of the most effective ways to counter such challenge is to improve the research and development activity at the firm. RIM therefore will require a constant inflow of talented and creative software developers to continue to develop better and more consumer friendly applications for RIM. This is critical in order to not only continue to hold the attention of the consumers but also successfully negotiate with the competition. If RIM does not ramp up its R&D quickly, it can soon see itself out of the business. This is because the overall competitive threat is quite huge not in terms of hardware side but also on software side too. Apple and Google have launched phones which can be considered as direct competitors of RIM’s Blackberry. (Peers). Similarly, Microsoft has come up with a new operating system allowing users to have better experience because the overall trends are shifting towards meeting social networking needs of the consumers rather than allowing them to h ave better productivity at work. Q#2 It has been observed that the concentration of software developers is regional based wherein major hubs of producing quality software developers are in few countries or regions. Most importantly countries like India and US are considered as the international hubs for the quality supply of qualified software developers.

Leishmaniasis Disease Emergence and Re-emergence Analysis Essay

Leishmaniasis Disease Emergence and Re-emergence Analysis - Essay Example In the previous decade, endemic areas have extended, occurrence increased and the substantial unrecorded cases of the disease identified. Leshmaniasis is one of the most significant human vector-borne disorders. Leishmania parasite causes nodules and skin ulcers to individuals. Numerous Leishmania parasites can have an effect on mucous membranes of an individual and may cause nose disfiguration (Ashfold & Bettini, 1987). In addition, other leishmania species may harm the internal body organs of an individual. According to a report by Ready (2010), dogs are the most significant domestic animals in epidemiology of Leishmaniasis. This is because dogs are reservoir hosts for L. Infantum, a significant organism in human visceral Leishmaniasis. Leishmaniasis is caused by species of leishmania, a protozoan that belongs to the family of Trypanosomatidae. Leishmania genera are divided into two subdivisions that are Leishmania and viannia. These two different types of parasites live and multip ly in the digestive tract of causative agent. The difference between the two sub divisions lies in where they multiply in the digestive system of the causative agent. Human leishmanisis is caused by leishmania which is transmitted between individuals who are reservoir hosts. ... In this regard, the activity of the sand flies intensifies at dawn, dusk and at night when perturbed in their hiding places. Sand flies are always attracted by light at night and enter buildings at night, bite people and cause the spread of Leishmaniasis. Leshmania parasite may also be transmitted by canine fleas and ticks (Ashfold & Bettini, 1987). Ticks are most importantly used to transmit the parasite between dogs. Presently, sand fly transmission seems to have reduced due to the effects of global warming. Global warming has brought changes in the climate which has caused hot regions to be hotter and cold regions to be colder. This change in climate has adversely affected the activities of sand flies whose activities are high when it is cool, humid and fewer rains. Present transmission seems to be done by mammals that can traverse the harsh climatic conditions. Leishmaniasis disease was initially termed as a disease of the rural areas. Presently, large outbreaks have been reporte d in large cities across the world because of encouraging epidemiological conditions linked to the reduction of natural ecological space of the vectors due to droughts, deforestation due to population growth and famine which are effects of climate change (World Health Oragnization, 2009). Mammals can remain infected with Leishmania for long and can still infect with the parasite even after clinical cure. Infected mammals can in turn transmit the parasite to sand flies. Presently, the parasites have been transmitted to people through blood transfusions in dogs and people (Ready, 2010). Leishmaniasis may also be caused by l. infantum which can be transmitted through saliva, semen, urine and conjunctiva secretions and blood. In the contemporary world, the

The Benefits of the Universitys Agricultural Patents Article

The Benefits of the Universitys Agricultural Patents - Article Example The cell line defends stops the growth of mycotoxins. Within the global food environment, Mycotoxin-infected agricultural products precipitate economic losses (DAR, 2006). University of Illinois (2013) offers Agriculture-based courses for farm enthusiasts and entrepreneurs. With the ARS and-University of Illinois patent partnership, the outcome is the improvement of our nation’s agriculture product outputs. The partnership ensures there is abundantly safe top quality food on the American people’s tables. The service helps its citizens, communities, and entities generate economic gains from agriculture transactions. The service scientifically conducts research to solve the nation’s agricultural problems. Solving includes protecting the agricultural products from identified pests (DAR, 2006). The purpose of the patent is to improve the nations’ agricultural food product scene. The improvement includes reducing the economic loss from infected agricultural food products. The research finds ways to reduce or eliminate the harmful effects a certain aflatoxin strain. Aflatoxin reduces the agricultural food products’ quality (DAR, 2006). Further, the ARS partners with University of Illinois to create anti-toxin defenses. Certain fungi produce mycotoxins. The mycotoxins crop up and develop on certain plant types. The plant types include barley, corn, wheat. Aflatoxin is one type of mycotoxin, a toxin (having ill effects) substance (DAR, 2006). The patent has many future applications. The patent will ensure an increase in farm plant outputs. With the anti-toxin patent, the University of Illinois and the United States Governments Agricultural Research Service increases the supply of plant food. With more food, the U.S. Governments hunger statistics is reduced. More food supply contributes to the reduction of farm food prices.  

The Green Anaconda Essay Example | Topics and Well Written Essays - 750 words

The Green Anaconda - Essay Example The Eunectus marinus, also known as the ‘’Green Anaconda’’ is the best know of these species. Possibly lizard posterity, these snakes contain hints of pelvic and hind limbs. The workings of an Anaconda’s body are mostly unknown, with only theories concerning the two working lungs present inside it in contrast to the usual elongated one (Pinney, 1991). The Green Anaconda is usually found inside rivers, marshes and lakes in South America predominantly in the basins from Venezuela to Argentina. In some places, they also live in flooded grasslands. In dry weather, they seek refuge in caves. Their skin color helps them to camouflage themselves in the river’s contents. These anacondas are excellent swimmers and keep to their territory, which varies during the year (National Geographic, web). The Green Anaconda is built to best overcome its prey. Its lean, strong body coils around its victim, squeezing them until they die of suffocation. The muscle b ones are somewhat relaxed, the lower jaw and the upper jaw not joined and the surrounding muscles powerful, enabling the anaconda to swallow victims larger than normally possible. The thick skin and the razor sharp teeth that turn towards the back of its mouth leave the prey helpless against this deadly predator. The teeth’s function is hardly biting down or even gnawing, they are a means of trapping the prey (Thorbjarnarson, 1995). The Green Anaconda is believed to be a patient predator, mainly hunting in water bodies. It estimates the size of its victim by contrast with the size of its mouth. With only its eyes and mouth above water, the anaconda senses its prey through vibrations occurring though the water. Once its victim is close enough, in order to keep it in place, the anaconda bites it, quickly coiling its large body around it in order to suffocate and then, swallow its meal. When the anaconda squeezes its victim, it simultaneously breaks their spine or neck. The Anac onda’s usual victims are deer, pigs, turtles and sometimes, jaguars (Murphy, 1997). These victims are swallowed completely. Owing to the Green Anaconda’s slow metabolism, this snake can survive for as much as a few months. The length of time is decided by the size of its prey. This phenomenon has allowed the anaconda to survive in droughts and famines. On the other hand, food is not the only motivation for hunting. Hunting is considered to be correlated with successful mating (Pinney, 1991). The Eunectus marinus’s mating is very complex. Pheromones are secreted by the female in order to attract the male. A group of males gather around one female during the end of the March. An accumulation of males (even as many as twelve) form a ‘’mating ball’’. Shallow waters usually host the call for these. Male anacondas try inserting their hemipenes, into the female’s cloaca. In preparation for copulation, the male anacondas also try famili arizing themselves with the female anaconda’s smell. Once a male manages to insert a waxy plug in the female’s cloaca, she is prevented from further fertilization (Rivas, 2001). Once pregnant, the female can no longer feed for as long as she carried the offspring, which can be as long as six to seven months. The eggs of an Anaconda hatch within the female and come out as in their normal physical form. The eggs can be up to one hundred. The Anaconda does not portray any parental inclinations. The closest

The Roles of Amino Acid R-groups in the Structures and Functions of Research Paper

The Roles of Amino Acid R-groups in the Structures and Functions of Transmembrane Ion Channels - Research Paper Example The figure above shows the unionized form of a group of amino acid called alpha (Elsevier 19). The R represents an organic substituent or a side-chain, which is specific to each of the amino acid. There is a carbon atom called ?–carbon attached next to a group called carboxyl. Ion channels refer to the proteins that form pores which help to establish the small changes in voltage in cells plasma membrane, flowing down with the varying electrochemical change. Transmembrane potential refers to electrical potential difference in a biological cell’s interior part and exterior. This potential arises from the interaction between action of proteins containing transmembrane embedded inside it and the membrane itself. The proteins get pushed to cause change in concentration by use of ion transporter or pump. Materials and methods In order to study the ion channels, voltage clamp particularly patch clamp and RT-PCR scientific based technique used. Experimentally, ion channels cata lyze the process of diffusion across membranes, and this recorded as electrical currents in units known as Pico amperes. Other methods used in this study include Partitioning methods, which commonly can be used to evaluate hydrophobicity of amino acid, surface area and chromatography method. Results Two levels of current which correspond to the open and closed state. The transition in the two conditions observed to be extremely fat to a measurement recorded of millisecond. From one level to the other, rectangular jumps produced between the two levels. The current indicated by the amplitude of the jumps. Channels show rates of ion flux up to 106 ions/sec. Channels only open in a few seconds but during this time ions flowing through the pore register thousands (Davies 255). Discussion The structural parts of proteins comprise of amino acids in chains. They normally appear linked together in different sequences forming various types of proteins. Standard group of these amino acids comp rise of twenty of each amino group into polypeptides. This natural made process. A group of nine of these amino acids called essential in human beings because their creation not normally dependent on creation by man but must be taken as food. The amino acids prove to act as a substitute from nutrition fertilizers, and commonly applicable in food technology, in many industries. They have industrial applications as catalysts during production of plastics, which can be biodegraded. In the study of ion channels, their function include making possible the ions diffusion across membranes, which have biological nature. A bioelectric barrier built between the molecules, which have charges or hydrophilic, also called electrical insulators. The ion routes supply hydrophilic or high conductivity pathways in the interior of the hydrophobic. The pore structure catalyzes the transportation of molecules with charges across a medium with low dielectric. The channel of this site catalyzed normally r emains to be open or closed. Where the ion shows to be associated tightly with the catalyzed site, the confrontation of open channel shows the enzyme-substrate state. This confrontation state arising between the open state and the closed compared to opening and closing of a gate hence referred to as

Elder abuse Essay Example | Topics and Well Written Essays - 750 words

Elder abuse - Essay Example Remember that perpetrators spend months, and sometimes years, to set up their victims for exploitation. Conclusion: By the time Patricia Murtaugh was finished with her two victims, she had emptied their bank accounts of almost half-a-million dollars and used the money to open up a business and purchase homes, cars, and a boat. Her victims were broke and although Murtaugh was arrested and convicted for her crimes, it is doubtful that they will ever see their money again. Murtaugh went to jail, but most victimizers get away with their crimes. Breton, T. (January 9, 2007). A Trust Betrayed: How Two Women in Their 90s Were Fleeced by a Helper. Rhode Island News. Retrieved from http://www.projo.com/news/content/Murtaugh_01-07-07_2034LD5.21a31c1.html. We’ve all heard, I’m sure, of severe cases of elder abuse, in which older people are physically abused by younger people, usually family members. There are some horrific cases of the elderly being victimized, sometimes to the point of death. I’d like to talk about another type of elder abuse—economic exploitation, which is often just as devastating. One of the most notorious cases of economic exploitation of the elderly happened in 2007 in New York. Patricia Murtaugh swindled hundreds of thousands of dollars from two women in their nineties, women who had spent fifty years wisely saving their money. Over a period of months, she gained their trust and then stole their life savings. At first, she was helpful, providing both women with the assistance so that they could keep their independence, in the form of bill paying and much-appreciated companionship. Eventually, she was able to gain access to their finances, a common approach of many a victimizer. This kind of elderly abuse is more common than you may think. One in five elderly Americans are victims of financial exploitation, and in some areas, that figure may be as high as 50%.

The European sovereign debt crisis during 2010-2011 Essay - 1

The European sovereign debt crisis during 2010-2011 - Essay Example Matters involving liability crisis have in the recent years being reported globally, as the level of the sovereign arrears of some of the financial scheme of the world have risen, giving them a threat of failure to pay. A Financial network is thought to be in an obligation crisis once its government has failed to pay its debt. However, not any of the nations that are at present in debt disaster has defaulted, but they involve extremely high government debt balances, and their bond output spreads in the securities of the government have gone up, as a result, there is relegation of their sovereign ratings for credit. When an area suffers this crisis, it might be able to undergo a sudden discontinue of inflows from the foreign capital because of major loss of capitalist confidence regarding the economy. The Eurozone had kept an overall acceptable short-term financial credit between 1999 to the year 2007. However, there existed large as well as continuing inequities in the region.  "Greece, Spain, Portugal, and to a lesser extent Ireland†, sustained massive current account shortfalls, and Germany, Netherlands, along with Luxembourg, had profits in the account (Braga & Vincelette 222). The providers of the large plus extended current account losses are dissimilar across these countries. As years went by, the deficits balances of the current financial standing have been increasing, also, a decrease to the surpluses in the other countries. The existing crisis on debt commenced with the demise of the banking corporation in Iceland in the year 2008, and spread to some of the countries in Europe like the Ireland, Portugal, as well as Greece in the year 2009. At the beginning of the second half of this year, reports concerning the debt crisis on the United Sates also blew up (Economic Review 1; Braga & Vincelette 222-225). The crisis originated from various factors and had tremendous implications to the economy of the European countries. GDP Growth in the Euroz one, Q4 2009–Q1 2011 (Belkin, & Mix, & Nelson, 14) Source: International Monetary Fund, World Economic Outlook, April 2011 (Belkin, & Mix, & Nelson, 4). Reasons behind the Financial Crisis The debts predicaments are featured to pro-cyclical economic policy in the period preceding the economic crisis. The countries impinged on had being managing large and untenable fiscal deficits for several years, largely funded through borrowing. The Government of Greek used deficit spending to increase extraordinarily, the people’s standard of living as the debt funded the joblessness societal benefits, raised the remuneration of public workers along with pensioners’ income, and sustained a mutually respectful labor market. The evident cause of the â€Å"European Debt Crisis† is also the changing of the ‘European Monetary Union’ (EMU) from financial stimuli to fiscal consolidation in the year 2009. Until that year, the EMU together with the entire European Union (EU) and other main financial systems followed the IMF order in the upshot of Lehman Brother’s insolvency, to promote global demand by way of increasing government spending. The
