The Deadly Hazard of Avalanches

The Deadly Hazard of Avalanches Avalanches have always occurred in the mountainous regions of the world. With the growth of winter-time recreations, fatalities have been on the rise since the 1950s. Avalanches claim over 150 lives each year worldwide and hundreds more are injured or trapped following an avalanche. Ninety percent of all avalanches occur on moderate slopes with an angle of 30Â ° to 45Â ° (snow tends not to accumulate on steeper slopes). Avalanches occur when the gravity pushing the collection of snow at the top of the slope is greater than the strength of the snow itself. A change in temperature, a loud noise, or vibrations are all that are necessary to trigger one of these snowfalls that begin at a starting zone. The avalanche continues downslope along the track and ultimately the avalanche fans out and settles in the runout zone. What Country Gets the Most Avalanches? Internationally, the Alpine countries of France, Austria, Switzerland, and Italy experience the greatest number of avalanches and loss of life annually. The United States ranks fifth worldwide in avalanche danger. The states of Colorado, Alaska, and Utah are the most deadly. Avalanche Prevention and Control Avalanche prevention and mitigation involves a variety of methods. Snow fences are built to prevent the buildup of snow in starting zones, structures are built to stabilize snow. deflecting walls are built to divert avalanche flows away from buildings and even entire towns. Sheds build across roadways that pass through persistent avalanche paths can help to protect motorists from avalanches. Additionally, the reforestation of slopes with trees helps to prevent avalanches. Sometimes avalanche control experts actually desire to create smaller, controlled avalanches to prevent larger, uncontrolled ones. Percussion guns, explosives, and even artillery have been used to produce these controlled avalanches when people are kept away. Although a variety of recreationists spend time in snow-covered mountains - snowmobilers are those most often killed by avalanches in the U.S. Most avalanches in the U.S. occur during the months January, February, and March and on average, 17 are killed annually nationwide. Backcountry explorers are strongly advised to not only know how to identify avalanche hazard areas but also to carry an avalanche beacon/transceiver and a shovel in case of emergency.

Managing Aircraft Maintenance Projects Successfully Research Proposal

Managing Aircraft Maintenance Projects Successfully - Research Proposal Example Regulations and common sense both mandate that each aircraft be the subject of a fully documented maintenance protocol towards ensuring the airworthiness and serviceability of the aircraft. Routine preventive maintenance, although well within the purview of common sense, is not a required part of the maintenance protocol. Within the aircraft maintenance protocol, each aircraft and the work required for its service is regarded as an individual project. The reality of aircraft maintenance project management (AMPM) is that several overlapping projects must be managed simultaneously. This presents major obstacles and difficulties for the aircraft maintenance organization in terms of resource management and utilization, budgetary constraints, priority conflicts and lead-time fulfillment. These considerations are compounded by several factors. Greater demands are being placed on aircraft as the number of passenger miles being flown trends upward over time. The number of aircraft being flown also trends upward but at a disproportionate rate. More importantly for the proposed research, the number of aviation maintenance technicians in the industry trends upward at a much lower rate, suggesting that the workload placed on maintenance technicians per capita is becoming ever greater. Air Transport Association o f America statistics for the 12-year period from 1983 to 1995 gives these increases as 187%, 70% and 27% respectively, supporting the ‘work overload’ factor of AMPM. Baron (2009) discusses at some length untoward events that can be attributed directly to the effects of fatigue experienced by aircraft maintenance personnel, and so to the project management practices of their working environments. It is important to note the finding recounted by Baron from a study conducted by Johnson et al in 2002. Based on quantitative and qualitative data, those authors discerned that in general, AMTs and AMEs working in aircraft maintenance services were

Blood component therapy Assignment Example | Topics and Well Written Essays - 2500 words

Blood component therapy - Assignment Example It has been observed that there is a disorganized practice to place the orders for blood requirement in elective surgeries moreover incidence show a wasteful use of blood in the execution of elective surgeries (Gianoutsos, 2008). It is therefore essential that there should be an approach of â€Å"group and screen† procedure compared to going for the full cross-match once transfusion is compulsory and therefore orders must be placed accordingly (Gianoutsos, 2008). In order to avoid the occurrence of hepatitis and HTLV-III infections, an approach of predeposit autotransfusion was realized specifically in elective surgery. This facilitates the conservation of homologous blood and creates an awareness and understanding for the proceeds of autotransfusion (Rebulla, 1987). This kind of approach finds its way through the advancement in the use of preservatives. The method has the advantage over the homologous transfusion where an individual receives the donor’s blood and hence risk life with hepatitis (risk is 46%), malaria, syphilis, allergic reaction (risk is 20 -25%) and mismatches due to any technical errors (risk is 61%). It is therefore essential for planned surgeries to have an autologist transfusion of blood to eliminate risks as it speed up the healing process (Holm, 1981). In order to find out the extent to which autologous blood that has been donated in advance and is used by the patient during the process of elective surgery, a study was carried out where 4996 patients undergoing elective surgery, of these, 1287 patients placed order for cross-matched blood even though 590 patients were found to be suitable for predepositing blood suggesting unawareness about predepositing blood. Merely 5% (32 patients) of the patients predeposited the blood, still 4 amongst these got homologous blood. The study concludes that by predonation of blood 68% homologous blood transfusion could have been avoided (Toy, 1987). This is autologous

Caribbean Music and the Influence It Has on the Caribbean Music Essay

African music and history of African music in the Caribbean; Identify and list some of the common African influences/features found in Caribbean folk and popular music. African music: music of the music of the Africa diaspora was refined and developed during the period of slavery. Slaves did not have easy access to instruments, so vocal work to on new significance. Through chants and work songs people of African descent preserved elements of their African heritage while inventing new genres of music. The culmination of this great sublimation of musical energy into vocal work can be seen in genres as disparate as Gospel music and Hip hop. The music of African diaspora makes frequent use of ostinato, a motif or phrase which is persistently repeated at the same pitch. The repeating idea maybe rhythmic pattern, part of the tune, or a complete melody. (wikipedia, 2013) The History of African music in the Caribbean : without a doubt the influence of black African music has spread worldwide and has a profound effect on music virtually everywhere. Caribbean music especially started to be influenced by the African heritage when slave trade was originally brought to the Caribbean and the Americas. There are different genres of music but the steel bands, calypso, and reggae. Listening to Caribbean music can definitely have a very positive affect on your mood. It will give you a real â€Å"good feeling† and help highlight your day. For the most part the music stemming from the Caribbean is happy, vibrant and â€Å"fun like.† The unique sound of steel drums (or pans) takes your mind straight to the Caribbean. Instantly you think of palm trees, spectacular long sandy beaches, hot sunshine days, long cool drinks and everything at your disposal to make your life easier and more tranquil. Steel pans (drums) have roots in Africa but its home is de finitely in Trinidad. Steel pans evolved in the 1930’s replacing the original banned tamboo bamboo. A bamboo was originally cut to various lengths and sizes and was made into the main instruments. Reggae is one of the best known genres of music, which first came famous in the 1960’s especially in the United States. Reggae’s home is Jamaica and the world capitol has to be Kingston, Jamaica. Reggae’s development is partially due to African and Caribbean music, Ska, Rocksteady, and American R&B. Artists such as Desmond Decker, Jimmy Cliff, Prince Buster and the Legendary Bob Marley breathed special life into reggae and it officially came to be prominence around 1967-1968. Bob Marley was probably the everlasting king and his masterful influence will live on forever. Think of Calypso, think great rhythms and let the music of the Caribbean take off to a better more beautiful place. It will help inspire you. (Jeszke, 2010) African –Caribbean music: is a broad term for music styles originated in the Caribbean. These types of music usually has an West African influence because of the presence and history of African people and their descendants living in the Caribbean, as a result of the trans-Atlantic slave trade. (wikipedia, 2013) Most notably: * Music of Cuba * Music of Puerto Rico * Music of Haiti * Music of Jamaica * Music of the Bahamas * Music of Dominican republic * Music of Trinidad and Tobago * Music of Venezuela * Music of Columbia * Music of Guyana * Music of Barbados * Music of Panama * Music of brazil Trinidad and Tobago: Calypso and Soca Puerto Rico: Salsa music Martinique: Zouk Dominican Republic: Merengue Jamaica: Reggae Zouk Music: is a style of music originating in Guadeloupe and Martinique 1uring the 1980’s. The conventional Zouk sound has a slow tempo, and it is sung in Antillean creole, although it also has varieties that have developed on francophone Africa.it is popular throughout the French speaking world, including France and Quebec. Jamaica: An early form of African-Caribbean music in Jamaica was junkanoo, (type of folk music) and work songs were the primary forms of Jamaican music at the beginning of the 20th century. These were synthesized into mento music, which spread across the Caribbean. Trinidad and Tobago: Trinidadian folk calypso is found throughout the area, as are African-Caribbean religious music styles like the Shango music of Trinidad. Calypso’s early rise was closely connected with the adoption of carnival by Trinidadian slaves, including camboulay drumming and the music masquerade processions. In the 1970’s, a calypso variant called Soca arose, characterized by a focus on dance and rhythms rather lyricism. Soca has since spread across the Caribbean and abroad.

Analysis Of Kenneth Branagh s Hamlet - 1044 Words

It is not easy to make a film that is based upon a play that was written four hundred years ago by a brilliant writer named William Shakespeare. The one person who I felt caught every line and scene was Kenneth Branagh’s Hamlet. Adapting even the works of the great William Shakespeare is a daunting task, but it takes the right mind of a director and writer to fully capture his imagination onto the big screen or on stage. If you do not know who that person is, you must be living under a rock. Literally. One of his great plays, The Merchant of Venice, was adapted onto film by a director named Michael Radford. Nowadays, comic books, novels, plays, etcetera, are being made because they contain good stories to tell to the audience. Characters that come to life in front of us on the silver screen just as we were reading them on a page. Everyone has their favorite character, either Batman, Superman, Wonder Woman, Harry Potter or Hermione (which is a character from one of Will iam Shakespeare’s plays) and many more. One particular character that was my favorite was the main one in Merchant of Venice, Antonio. Yes, because he was played by Jeremy Irons in the movie helped me understand the character more by imagining what he would look like on film. I think his character played a major role in the difference between the movie and from the play. What he was like in the play compared to the movie, and which interpretation was best. What I find most interestingShow MoreRelatedInside A Or Inside Looking Out Essay1721 Words   |  7 PagesThat is thy question. Who is prince Hamlet? What is he like? Hamlet is one of the most dynamic, if not the most dynamic character, in the play Hamlet. He happens to be on of the most eccentric beings that Shakespeare put in his works. Throughout the play, he was someone who endured a lot of adversity and did not even sweat a drop from his brow. He stayed cool and displayed his best features. His honesty is admirabl e also his heart that is like that of a lion. Hamlet is a person who is very blunt and
