Ã There are so many things happening in our world that its hard to keep up with everything that going on. One thing that not many know about are the earthquakes in Alaska. Lots of people are surprised to find out that Alaska has earthquakes. Though Alaska is actually pretty used to earthquakes. Alaska records an average of 40,000 quakes every year. Earthquakes in Alaska date all the way back to 1899. The earthquakes happen because parts of Alaska sit of fault lines. Fault Lines is a fracture along which the crust has moved. Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. When the rocks break, the earthquake occurs. Right now in Alaska they are having some major earthquakes. These earthquakes can go all the way up to 7.0 magnitude. These Earthquakes occurred on November 30, December 1, and December 4. All of these earthquakes are about 3 to 12 miles from Anchorage. These earthquakes have had a major aftermath on the roads. The damage on the roads range from large cracks to fall and caving in of the roads. More than 1,000 aftershocks have shaken Alaska since the magnitude 7.0 quake last week. While the majority of the aftershocks were measured at magnitude 2.5 or less, about 350 small earthquakes were higher than 2.5 and around a dozen registered higher than magnitude 4.5. The original quakes core was about eight miles north of downtown Anchorage and caused structural damage to buildings and roadways. Fortunately, no deaths or injuries were caused by the quake. There is major infrastructure damage across Anchorage, said the Anchorage Police Department. Many homes and buildings are damaged. Many roads and bridges are closed. After a long night of aftershocks, Randall Cavanaugh, an Anchorage attorney, told the Press, Theyre disturbing, and Im not putting anything away that could fall until they calm down. I kept waking up. (www.csmonitor.com) State seismologist Mike West called the immense tremble the most significant in Alaska since the Alaskan earthquake of 1964, the Anchorage Daily News reported. The Alaska earthquake of 1964 was the most powerful earthquake in U.S. history and second in the world. This strong earthquake had a magnitude of 9.2. A city official stated that thousands of residences have no electricity right now, on the evening of November 30. Anchorage Municipal Manager Bill Falsey said on Friday, Progress was being made restoring power and utilities arent expecting protracted outages. Falsey also said City workers were responding to reports of 28 mainline water breaks and dozens of requests to cut off residential service because of flooding. The Governor of Alaska, Bill Walker, says it will take more than a week or two to repair the damaged roads. Walker says that he spoke with President Trump and was guaranteed by the White House that help was on the way. President Donald Trump has tweeted that the federal government will spare no expense helping Alaska after the high magnitude earthquakes. Trump on Friday tweeted you have been hit hard by a big one' and asked residents to follow officials directions. Press Secretary Sarah Huckabee Sanders tweeted Friday that Trump is monitoring the reports of damage. Right now in the process of rebuilding and recovering, officials are warning residents to stay off the roads. On saturday, officials encouraged Alaskans not to go the grocery stores, saying there was no reason to stock up on food. Schools are also closed, which they said will reduce the traffic. About 90 percent of all the goods sold in Alaska are delivered to the Port of Anchorage, where they have completed a prior destruction evaluation. Everything looked good, said Municipal Manager Bill Falsey. There was some structural concerns with some of the trestles. We have got some things on a watch list but nothing that should impede operations. Two large cargo companies operate at that port. One was unloading as normal on Sunday, and the other company is scheduled to carry barges on Monday after they have successfully tested their crane system.

Report the error and the planned recovery actionsD. Assess alternatives to meet the milestone Answers The answers to the PMP sample questions are fromÃ Scribd, a fee-based information website. Answer 1 B - Explanation: The Delphi technique is a commonly used tool to secure expert judgment while initiating a project. Answer 2 B - Explanation: Project III has an IRR of 15 percent, which means the revenues from the project equal the cost expended at an interest rate of 15 percent. This is a definitive and a favorable parameter, and hence can be recommended for selection. Answer 3 C - Explanation: A WBS is a deliverable-oriented grouping of project components that organizes and defines the total scope of the project. Answer 4 D - Explanation: A start-to-finish (SF) relationship between two activities implies that the completion of aÃ successor is dependent on the initiation of its predecessor. Answer 5 B - Explanation: The project team must complete a scope statement for developing a common understanding of the project scope among stakeholders. This lists project deliverables -- summary level sub-products, whose full and satisfactory delivery marks the completion of the project. Answer 6 A - Explanation:Ã The organizationÃ¢â¬â¢s reputation being at stake, the threshold for such a risk would be very low Answer 7 B - Explanation: The critical path is the longest duration path through a network and determines the shortest time to complete the project. The PERT estimates of the tasks listed are 27, 22.5 26. Therefore, the length of the critical path of the project is 2722.526 75.5. Answer 8 D - Explanation:Ã Determining theÃ validity of quality standards, followed by the project is a quality assurance activity. Answer 9 D - Explanation: Individual development (managerial and technical) is the foundation of a team. Answer 10 A - Explanation: A Project plan is the basis of project plan execution and is a primary input. Answer 11 A - Explanation: In a functional organization, the project team members have dual reporting to two bosses -- the project manager and the functional manager. In a weak matrix organization, the power rests with the functional manager. Answer 12 A - Explanation: Number of communication channels with Ã¢â¬Å"nÃ¢â¬ members n*(n-1)/2. Originally the project has 25 members (including the project manager), which makes the total communication channels as 25*24/2 300. With the addition of the quality professional as a member of the project team, the communication channels increase to 26*25/2 325. Therefore, the additional channels as a result of the change, that is, 325-300 25. Answer 13 A - Explanation: Project records should be prepared for archiving by the appropriate parties. Answer 14 B - Explanation: Common formats for Performance Reports are, bar charts (also called Gantt Charts), S-curves, histograms, and tables. Answer 15 C -Ã Explanation: Positive Schedule Variance means the project is ahead of schedule; Negative Cost Variance means the project is over-budget. Answer 16 A - Explanation: The question is about correct accounting for risk events that occur and updating the reserves. Reserves are meant for making provisions in cost and schedule, to accommodate for consequences of risk events. Risk events are classified as unknown unknowns or known unknown, where Ã¢â¬Å"unknown unknownsÃ¢â¬ are risks that were are not identified and accounted for, while known unknowns are risks that were identified and provisions were made for them. Answer 17 B - Explanation: Archiving is the last step in the project closing. Answer 18 A - Explanation: Stakeholders include everyone who is actively involved in the project or whose interests may be affected as a result of the project execution or completion. The project team creates the lessons learned on the project.Ã Answer 19 C - Explanation: Understanding cultural differences is the first step towards an effective communication amongst the project team involving outsourced work from a different country. So, what is needed in this case is an exposure to the cultural differences, which is being mentioned as choice C. Answer 20 D - Explanation: Choice D, that is, assess alternatives to meet the milestone indicates confronting the issue with an attempt to resolve the issue. Hence this would be the best approach.

In this essay, it will be looking at how Emile Durkheim s theory of morality and comparing and contrasting it with Zygmunt Bauman s postmodern ethics. Durkheim s theory of morality is set out to understand morality as a social phenomenon. Durkheim experienced social change in his era and his theory of morality looks at ideas concerning change in social and existential conditions. Durkheim, (1953. p.37) states at morality begins with membership of a group, whatever that group may be. When this premise is accepted the characteristics of the moral fact become explicable. Firstly Durkheim s theory looks to the extent of how the individual needs society to be able to fully participate in day to day life and then on the other hand how society is greater than any individual, which leads to people looking to better themselves disregarding their own beliefs. Secondly looks at how society constitutes a moral authority by demonstrating a overall general rule to regulate behaviour. There have been objections to this stating that it subjugates the mind to prevailing moral opinion (Durkheim, p.38). The theory itself, looks at orientation towards something collective, so morality is moral feelings of selfless care. Something so that the individual would sacrifice themselves for something but there is a generosity about it, self-sacrificing element to morality but if morality is not self interest but the opposite.

Question: Cholera and Typhoid fever: Is there a misleading similarity? Answer: Introduction Cholera and Typhoid fever are major public health problems especially in developing countries as well as developed world. In 2016 more than five million people suffered from cholera and typhoid fever. Mortality due to cholera and typhoid fever occurs usually due to loss of fluid and secondary complications respectively. While they both are caused by bacterial infections and transmitted by the faeco oral route (from faeces to mouth) they are in truth, very dissimilar in various aspects. So, although cholera and typhoid fever are caused by bacteria and both microbes share similar transmission route, the people infected by cholera and typhoid fever exhibit different symptoms, affects different organ systems, have difference in the pathogenesis of disease and have different treatment regimen.This essay addresses the differences and similarities between cholera and typhoid fever on the basis of etiology, transmission, pathogenesis, symptoms, diagnostics, treatment, prevention and control. Body Both cholera and typhoid fever are diseases caused by bacteria. Vibrio cholerae serotype O1 and serotype O139 synonym Bengal causes cholera and Salmonella enterica serovar Typhi causes typhoid fever (WHO, 2008; WHO 2010). A similar but often less severe form of typhoid fever, paratyphoid fever, is caused bySalmonellaParatyphi A, B or C. Vibrio are small, gram-negative comma shaped rods, having single polar flagellum whereas Salmonella are gram-negative motile straight rods. Cholera and typhoid fever are transmitted by faecally contaminated food or water, by the faeco-oral route. The faeco oral route means pathogen can spread directly from contaminated hands touching the mouth and transmitting the pathogen directly :direct transmission; orthrough eating or drinking food or water contaminated with the infectious agents, or using utensils washed with contaminated water, ie indirect transmission. As both cholera and typhoid fever are diseases caused due to contamination in drinking wate r, poor personal hygiene and lack of sanitation, the incidence of them in Australia is limited. In Australia typhoid fever (approx. 150 cases each year in comparison to 21 million cases world wide) (Basnayat et al, 2005) and cholera (and even lesser in comparison to a total of 172454 cases worldwide) (NNDSS, 2010) are both predominantly travel related disease with more frequency in people travelling from the Indian subcontinent (Dale, et al, 2010) Cholera is an enteric disease (affects the gut) where as typhoid is a systemic infection (spread throughout) due to difference in their pathogenesis. When the bacteria Vibrio cholerae enters the intestine it releases cholera toxin which enters the enterocytes.On its entry in the enterocyte, the toxin induces adenylate cyclase to produce cAMP.The increased generation of cAMP stimulates cystic fibrosis transmembrane conductance regulator (CFTR), resulting in excretion of excess water and ions from entrocytes causing watery diarrhea.In case o f typhoid fever, S. typhi penetrate the enterocytes and then enter the macrophages. In these phagocytic cells S.typhi replicates before being released into the bloodstream which produces a systemic infection (Todar, 2012). Symptoms of cholera are characterized by acute onset of profuse watery diarrhea (described as "rice-water" stools) and frequently accompanied with vomiting. On the other hand, typhoid fever is characterized by prolonged low grade fever, intestinal dysfunction of the gut (constipation in adults, diarrhea in children), headache, a general feeling of discomfort and anorexia. Diagnosis of cholera and typhoid can be done by bacterial culture of stool and blood respectively. Serological testing may be also done to confirm cholera and typhoid fever. In case of cholera O1 or O139 antisera are measured and in case of typhoid fever Widal test can be done which estimates agglutinating antibody levels against O and H antigens. Prompt fluid replacement therapy is the core of t reatment of cholera to cure dehydration which occurs because of watery diarrhea. Antibiotics such as tetracycline, ciprofloxacin, doxycycline and co-trimoxazole may also be given to decrease the severity and duration of diarrhea In case of typhoid fever fluoroquinolones such as ofloxacin, ciprofloxacin, fleroxacin, perfloxacin are the antibiotics of choice. Rampant use of antibiotics may lead to formation of drug resistant pathogens. As both cholera and typhoid fever are waterborne and foodborne diseases, the principal measure is to ensure proper sanitation. Access to good quality and sufficient supply of water for drinking and for household chores will also prevent such diseases. Health education is crucial in making the public aware of dangers of diseases like cholera and typhoid and helping them in adapting good personal hygiene habits to prevent spread of diseases. Vaccines are also available for cholera and typhoid fever. Two types of oral cholera vaccines and a live oral vacci ne Ty2la is available for typhoid. Vi polysaccharide, a typhoid fever vaccine is also available which can be administered s.c. or i.m. Conclusion In summary, although Cholera and typhoid are similar but different, they are major public health problems, mostly in the developing world, emergence of drug resistant strains and worldwide spread due to global travel has renewed interest in these diseases. Public health awareness, better sanitation and good vaccine strategies are needed to minimize their public health impact.

Osiris and Isis Creation Myth Mythology opens up a hidden gate of information about the lives of ancient peoples. Through it, modern people have insight to the beliefs and culture of a civilization long since passed. No better example of this exists than the Egyptian tale of Osiris and Isis. According to this tale, when the world first started it was ruled by the benign god Osiris and his equally generous wife, the goddess Isis. Together they ruled the earth and through this time it was a utopia. Crops prospered, people spoke to each other in poetry, and there were no wars. It remained this way until Osiris was trapped by his wicked brother Seth, who then took full control of the world, exposing humanity to its first taste of heartache. Osiris was eventually freed and Seth dethroned, but when it came time to destroy Seth Isis didnÃ¢â¬â¢t have the heart. We will write a custom essay sample on Osiris and Iris Creation Myth or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page She let him live, and though he still exists he is now a lowly god with less power. This explains the Egyptian belief of why there has to be good and evil in the world. It also explains that since Seth has less power than Osiris, good will always trump evil. The Egyptians were so rare in their day because of their positive outlook on death. While other civilizations around them looked on to death in a craven manner, Egyptians embraced the beauty of the afterlife and the riches to come. All this stemmed from the belief that Osiris, an oh-so-benevolent god, would make their afterlife paradise, as he had once done here on earth. Because the afterlife is ruled by a kind god, it also explains the way to get there. Egyptians believe that through morality and kindness, they will forever be joined with their princely god in paradise. Egyptian culture stressed love and loyalty between husband and wife and that is clearly expressed throughout this myth. The story of Osiris and Isis is punctuated with IsisÃ¢â¬â¢s undying devotion to her husband and her willingness to go above and beyond to find him. Though Osiris is lost for many years on more than one occasion, Isis never stops searching for him. Even when he is sent to the afterlife, she follows. Readers can assume from the numerous examples of IsisÃ¢â¬â¢s loyalty that this was an important value to the ancient Egyptians. Through Isis modern people can see what the ideal Egyptian wife must have been. Osiris and Isis is a myth that has carried on through the ages, portraying an excellent well of information on what Egyptian culture was. Modern readers can see what the ideals and beliefs of a place (beliefs that are still followed today) which give a better understanding than any history book can. Ancient Egyptians held in high esteem what their gods taught and were quick to follow their example. Their conclusions on the afterlife, polytheistic pantheon and good vs. evil are all expressed in this myth. This myth offers us a glimpse into a long ago world, and is perhaps, along with the pyramids and ancient temples, one of the greatest gifts the ancient Egyptians have given modern society.

Why Swinging Puts You to Sleep (And Benefits of Sleep) SleepÃ is characterized by periods of non-rapid eye movement that are periodically interrupted by intervals of rapid eye movement (REM). It is in the non-rapid eye movement stage, that neuron activity slows and ceases in areas of the brain such as the brainstem and cerebral cortex. The part of the brain that helps us get a good nights sleep is the thalamus. The thalamus is a limbic system structure that connects areas of the cerebral cortex that are involved in sensory perception and movement with other parts of the brain and spinal cord that also have a role in sensation and movement. The thalamus regulates sensory information and controls sleep and awake states of consciousness. The thalamus reduces the perception of and response to sensory information such as sound during sleep. Benefits of Sleep Getting a good nights sleep is not only important for a healthy brain, but for a healthy body as well. Getting at least seven hours of sleep helps our immune systemÃ fight off infection from viruses and bacteria. Other health benefits of sleep include: Sleep Clears the Brain of Toxins Harmful toxins and molecules are cleansed from the brain during sleep. A system called the glymphatic system opens pathways to allow toxin containing fluid to flow through and from the brain during sleep. When awake, the spaces between brain cells decrease. This greatly reduces fluid flow. When we sleep, the cellular structure of the brain changes. The flow of fluid during sleep is controlled by brain cells called glial cells. These cells also help to insulate nerve cells in the central nervous system. Glial cells are thought to control fluid flow by shrinking when we sleep and swelling when we are awake. Glial cell shrinkage during sleep allows toxins to flow from the brain. Sleep Enhances Learning in Newborns Theres not a sight that is more peaceful than that of a sleeping infant. Newborns sleep anywhere from 16 to 18 hours a day and studies suggest that they actually learn while they sleep. Researchers from the University of Florida have demonstrated that an infants brain processes environmental information and produces appropriate responses while in the sleep state. In the study, sleeping infants were induced to squeeze their eyelids together when a tone was sounded and a puff of air was directed at their eyelids. Soon the babies learned to squeeze their eyelids together when a tone was sounded and no puff of air was administered. The learned eye movement reflex indicates that a portion of the brain, the cerebellum, is functioning normally. The cerebellum is responsible for the coordination of movement by processing and coordinating sensory input. Similar to the cerebrum, the cerebellum contains several folded bulges which add to its surface area and increase the quantity of information that can be processed. Sleep May Prevent Diabetes A study from the Los Angeles Biomedical Research Institute indicates that getting more sleep can lower the risk of developing Type 2 diabetes in men. The bodys ability to process glucose in the blood improved in men who had three nights of adequate sleep after limited hours of sleep during the week. The study indicates that adequate sleep improves insulin sensitivity. Insulin is a hormone that regulates blood sugar levels. Over time, high levels of glucose in the blood can damage the heart, kidneys, nerves, and other tissues. Maintaining insulin sensitivity reduces the chances of developing diabetes. Why Swinging Makes You Fall Asleep Faster By measuringÃ brainÃ wave activity in sleeping adults, researchers have determined what many of us suspected: that gently swinging makes us fall asleep faster and promotes a deeper sleep. They have discovered that rocking increases the length of time spent in a stage of non-rapid eye movement sleep called N2 sleep. During this stage, bursts of brain activity called sleep spindles occur as the brain attempts to stop processing and brain waves become slower and more synchronized. Enhancing the amount of time spent in N2 sleep is not only conducive to a deeper sleep but is also thought to help improve memory and brain repair mechanisms. Sources: Cell Press. Need a nap?

Bilateral Trade between China and Germany Essay Example | Topics and Well Written Essays - 250 words
Bilateral Trade between China and Germany - Essay Example According to the research findings, it can, therefore, be said that Ã GermanyÃ¢â¬â¢s imports and exports to China have increased by one-third over the last year. Even this year the growth trends remain steady, with bilateral trade experiencing a 28 percent jump from the same time last year. The truth of the matter is that Germany is attractive for the Chinese to invest in and vice-versa. These new trade connections have strengthened the relationship between China and Germany both politically and economically. China is looking to focus more on domestic consumption, which is something that is tempting for German companies to become a part of. On the other side of the coin, China can learn a great deal about German business practices and its advanced technology. This is very important to the Chinese economy because there is a lack of technological know-how among many Chinese manufacturing companies. Reciprocally, Germany can also do with the influx of Chinese investments because of the weakened economy within the European Union.
