Dates in June for Science, Trademarks and Inventors

Dates in June for Science, Trademarks and Inventors In the world of science, there are dates in June that are standouts for invention, patents, trademarks and a variety of achievements. Also worthy of mention are the birthdays of the men and women who made these innovations possible. For example, in 1895, the gasoline-powered automobile was patented in June. Also in June, a few years earlier (1887), the Coca-Cola bottle label was trademarked. A famous birthday, long ago, on June 7, 1502, was Pope Gregory XIII, who invented the Gregorian calendar in 1582, which is the same calendar in use today.

Imperialist vs Anti- Imperialist essays

Imperialist vs Anti- Imperialist essays The United States has had a long tradition of territorial expansion across the continent so it is easy to understand why the notion of imperialism was so easily accepted by such a large number of people. And to back this imperialist sentiment we had things like the Monroe Doctrine, the Manifest Destiny, Social Darwinism, overabundance of industrial goods, and the military advantages of acquiring new territory. There were others who felt much differently about the concept of imperialism. The other group of people felt it was wrong so they formed the Anti-Imperialist League. The Anti-Imperialist League fought and campaigned against imperialism. And aiding the anti-imperialist sentiment were the struggles for Cuban and Filipino independence, the true meaning of independence, Whenever we felt the need to expand our boundaries and acquire new territories we would purchase, negotiate, or conquer the desired land. These were the methods we used to acquire territories like Florida, Louisiana, Texas, New Mexico, California, and Oregon, from England, France, and Spain. Our imperialist ways are precisely the reason why we own as much of the country as we do. I mean if we would have left it up to England, France, or Spain they would still own the other half of our country. But, our imperialist motives did not stop there first we had the Monroe Doctrine, which expressed U.S. hostility towards Europeans intervening in affairs occurring in our half of the hemisphere. Later an idea called Manifest Destiny emerged this was the idea that since we were of Anglo-Saxon decent we were superior and our industrial, political, and military strength were proof of that superiority thus we carried the responsibility to extend our rule and prosperity to the less-able people.

Discover the Code-Breaking History of the Rosetta Stone

Discover the Code-Breaking History of the Rosetta Stone The Rosetta Stone, which is housed in the British Museum, is a black, possibly basalt slab with three languages on it (Greek, demotic and hieroglyphs) each saying the same thing. Because the words are translated into the other languages, it provided Jean-Francois Champollion the key to the mystery of Egyptian hieroglyphs. Discovery of the Rosetta Stone Discovered at Rosetta (Raschid) in 1799, by Napoleons army, the Rosetta Stone proved the key to deciphering Egyptian hieroglyphs. The person who found it was Pierre Francois-Xavier Bouchards, a French officer of engineers. It was sent to the Institut dEgypte in Cairo and then taken to London in 1802. Rosetta Stone Content The British Museum describes the Rosetta Stone as a priestly decree affirming the cult of 13-year-old Ptolemy V. The Rosetta Stone tells of an agreement between Egyptian priests and the pharaoh on March 27, 196 B.C. It names honors bestowed on Macedonian Pharaoh Ptolemy V Epiphanes. After praising the pharaoh for his generosity, it describes the siege of Lycopolis and the kings good deeds for the temple. The text continues with its main purpose: establishing a cult for the king. Related Meaning for the Term Rosetta Stone The name Rosetta Stone is now applied to just about any type of key used to unlock a mystery. Even more familiar may be a popular series of computer-based language-learning programs using the term Rosetta Stone as a registered trademark. Among its growing list of languages is Arabic, but, alas, no hieroglyphs. Physical Description of the Rosetta Stone From the Ptolemaic Period, 196 B.C.Height: 114.400 cm (max.)Width: 72.300 cmThickness: 27.900 cmWeight: about 760 kilograms (1,676 lb.). Location of the Rosetta Stone Napoleons army found the Rosetta Stone, but they surrendered it to the British who, led by Admiral Nelson, had defeated the French at the Battle of the Nile. The French capitulated to the British at Alexandria in 1801 and as terms of their surrender, handed over the artifacts they had unearthed, chiefly the Rosetta Stone and a sarcophagus traditionally (but subject to dispute) attributed to Alexander the Great. The British Museum has housed the Rosetta Stone since 1802, except for the years 1917-1919 when it was temporarily moved underground to prevent possible bomb damage. Prior to its discovery in 1799, it had been in the town of el-Rashid (Rosetta), in Egypt. Languages of the Rosetta Stone The Rosetta Stone is inscribed in 3 languages: Demotic (the everyday script, used to write documents),Greek (the language of Ionian Greeks, an administrative script), andHieroglyphs (for priestly business). Deciphering the Rosetta Stone No one could read hieroglyphs at the time of the discovery of the Rosetta Stone, but scholars soon pieced out a few phonetic characters in the demotic section, which, by comparison with the Greek, were identified as proper names. Soon proper names in the hieroglyphic section were identified because they were circled. These circled names are called cartouches. Jean-Francois Champollion (1790-1832) was said to have learned enough Greek and Latin by the time he was 9-years-old to read Homer and Vergil (Virgil). He studied Persian, Ethiopic, Sanskrit, Zend, Pahlevi, and Arabic, and worked on a Coptic dictionary by the time he was 19. Champollion finally found the key to translating the Rosetta Stone in 1822, published in Lettre M. Dacier.

Research paper on global warming Essay Example | Topics and Well Written Essays - 1000 words

Research paper on global warming - Essay Example Research into the subject reveals that reducing greenhouse gasses through the development of renewable energy would provide tremendous benefits to the country. By understanding the effects of greenhouse gasses on the atmosphere we breathe, the water cycle we’re truly dependent on and the resulting effects these changes will have on the landmasses we live on, it can be seen how the development of new forms of energy can introduce highly beneficial changes into our lifestyles and future. The rising global temperature is and will continue to cause major changes to the environment which in turn will negatively affect the U.S. economy to an extent that can only be speculative. What is known is that the impact will be nothing short of catastrophic regarding both the earth and economy. Only by quickly implementing alternative sources of automobile fuel and electricity on a large scale can this looming disaster be averted. Worldwide, carbon dioxide emissions are creating widespread health impacts even as greater numbers of people begin using cars for longer distances (Dearry, 2004: A600). Eighty percent of the world’s population accounts for just 35 percent of CO2 emissions while the United States is responsible for generating nearly half of this amount. Automobiles are the main cause of air pollution with toxins emitted from stacks at coal-burning electric power plants running a close second (Dahl, 2005: A239). In addition to CO2 emissions, vehicles emit carbon mo noxides (CO), hydrocarbons (HC) and nitrogen oxides (NOx), all of which contribute to global warming (Energy Information Administration, 2004). At the same time, these emissions begin to break down the overall health of the population with increases in respiratory diseases and other illnesses as a result of the chemicals being pulled deep into our lungs (Carter in NOW, 2007). Thus, our

Coorinating Emergency Response - Crisis Management Essay

Coorinating Emergency Response - Crisis Management - Essay Example Myanmar Government preferred government to government aid. AmeriCares required permission for airlift supplies which was a challenging and proved to be time taking process. The efforts could have brought more differences in relieving people from suffering and dying. The political pressure was high in the case of efforts of AmeriCares. However during such kind of natural disaster the effort should be to ensure proper assessment of disaster, coordination among various teams of rescue efforts, proper flow of food, medical and other supplies for relief, coordinating response through public information officers and media channels, collaboration of global efforts for the rescue and relief operations, informing public about their lost relatives, friends and dear ones and informing general public about disaster. However political situation of Myanmar did not allow all these things. Once disaster takes place in certain area, depending upon the nature of disaster and damage caused to the communication network, disaster management team finds out alternatives for communication to ensure proper flow of communication. In major disasters, communication infrastructure gets damaged or destroyed. Government agencies and disasters management agencies should have an alternative communication strategy for disasters. The information sent or receive should be short, clear and simple. An effective communication strategy during any disaster supports the coordination activities and helps in rescue and damage control operations. The Transitional Fires are significantly dangerous as the exposure of firefighters is high on hourly basis and is very risky for them. It is highly risky for resulting in injuries and fatality. It is threatening for the firefighters and influences their level of motivations negatively. The crisis management and emergency response to the transition fire requires combined efforts of Forest Service Firefighters, researchers and analysts. These can

EB Outcomes Essay Example | Topics and Well Written Essays - 1000 words

EB Outcomes - Essay Example This paper will discuss the implementation of a change program covering poor hand washing among healthcare service providers at Veema center, which has been found to cause adverse outcomes, during service delivery (Titler, 2008). Planning for Change This stage will cover the phases of preparation (Phase I), Validation (Phase II), and Decision making/ Comparative Evaluation (Phase III) From the evidence given studies, including Garrette (2013) and Canham (2011) hand hygiene is acknowledged by control experts and infection prevention personnel, as the single and most effective measure that helps in reducing the spread of infections in the community and at health care settings (Garrette, 2013). This is the case, because the hands are transmission areas between individuals and the objects, as well as the surfaces within the healthcare environment. Some of the objects that can transfer infections in the healthcare setting include blood pressure cuffs. The means of hand hygiene include tha t of using soap and water, and using alcohol-based products, in the cases where water and soap cannot be used. The World Health Organization (WHO) and the CDC (Center for Disease Control and Prevention) maintain that hand hygiene can aid healthcare providers to uphold quality practice, and patient safety (Pittet, Allegranzi & Boyce, 2009). The practice of extensive hand washing will lessen the risk of infection between patients, lessen the infection of healthcare personnel, and lessen the cases of morbidity, mortality and the costs incurred during the treatment of infection-based conditions (Garrette, 2013). In preparation for the change, a survey was administered to the personnel at the health care center, aiming at realizing the factors limiting hand hygiene. Some of the factors explained as causes of poor hand hygiene at the health center and from studies like Garrette (2013) and Pittet, Allegranzi and Boyce (2009) include that hand washing agents leads to dryness and the irritat ion of the skin; sinks are not available in convenient areas and there is also a lack of soap, water, and disposable towels for drying hands. Others include understaffing, giving priority to patient care needs, disagreement with hand hygiene directives and the low risk of getting infected by patients (Cambell, 2010). Towards ensuring that the factors affecting hand hygiene at the Veema health center are addressed through consulting the medical personnel at the center, when developing the best recommendations on hand hygiene. Secondly, the materials required for hand hygiene, which may not be available should be supplied at all times and hand washing areas should be available at all areas, including wards, casualty and admission centers. From the evidence of studies like Garrette (2013) and Pittet, Allegranzi and Boyce (2009), alcohol-based agents should be used for hand washing, before and after patient contact, after removing gloves, and in emergency situations where water is not a vailable. Implementing the EBP Project (Phase IV Translation/ Application) Towards the implementation of the project, a team will be formed, comprising of staff nurses and doctors, clinical nurse specialists, departmental nurse administrators, nurse and doctor researchers and infection control nurse and

Real Estate Price Volatility Research Paper Example | Topics and Well Written Essays - 1000 words

Real Estate Price Volatility - Research Paper Example In this context, the present paper attempts to discuss about one of the early developed models that is still prevalent in the present economic scenario. The model was developed by R. Engle in 1982, which came to be known as Autoregressive Conditional Heteroskedasticity (ARCH). The paper also attempts to through lights on how effective is the model in the present real estate climate in the United States of America with particular reference to California. The paper takes an analytical approach wherein the model is suggested with a brief explanation of its application, merits and demerits. The various stakeholders (participants) in the real estate market comprising of real estate investors, banks, non-bank financial institutions, portfolio managers have always been curious to predict the local housing prices. Naturally, they have always encouraged the attempts to evolve mathematical models that can prevent the losses and chaos from the volatility of real estate prices. Parties who are also interested in housing prices estimating models include managers of banks, Real Estate Investment Trusts (REITs), and homebuilding companies. Prior models have tried to incorporate many of the macroeconomic variables including the bubbles and crashes in the stock market. Experts such as Alan Stockman and Tesar Linda, Lane Philip and Girouard N and Bl'ndal have described the housing price behavior from a dynamic general equilibrium point of view (Stockman and Tesar, 1995, Girouard and Bl'ndal, 2001 and Lane, 2001). Studies undertaken by Driffill John and Sola Martin explored the model in the context of market bubbles (Driffill and Sola 1998). Attempts have also been done to evolve a model that incorporate the interaction of an array of variables such as transactions in the real estate sector, changes in the demography of participants, and macro factors comprising of diversity in the income distribution and changes in the economic activity as a whole. For example, Francois Ortalo-Magne and Rady Sven have studied these aspects through a significant research (Ortalo-Magne and Rady 1998, 1999, 2003a and 2003b). Economic Analysis The model developed by R. Engle in 1982 is found relevant in the present scenario where traditional models that describe variables such as location factors, structural variables and floor area and income are no longer valid (Engle 1982). This model was coined as Autoregressive Conditional Heteroskedasticity (ARCH). The basic contention of this model is that housing price prediction should take care of time-varying volatility and studied through time series analysis. The Model The ARCH model was developed using mathematical and statistical notations and theories. For a better understanding of the model, the ARCH process consisting of conditional mean process and a conditional variance process will have to be known. The conditional mean process is developed in conformity to the standard Autoregressive Moving Average (ARMA) equation (Engle 1982). Where, Rt is the return on average home prices on a monthly basis, e, and s2 are constants. Through this model, Engle try to analyze and incorporate the pricing behavior with two
