About the Perseid Meteor Shower

The Perseid meteor shower is one of the best-known showers in the year. Its one of the great astronomy events of Northern Hemisphere summer and Southern Hemisphere winter. It begins in late July and extends halfway through August, peaking around August 11 or 12th. When conditions are good, you might be able to see dozens of meteors per hour. It all really depends on the weather and what part of the meteor stream Earth moves through each year. Also, the viewing is best when theres no interference from the Moon, although you can still see the brighter meteors as they flash through the sky.   This year (2017) the peak of the shower occurs not long after full moon, so its light will wash out the view of the dimmer meteors. You will likely see a few bright meteors during this time, but dont buy into the hype about the best, the brightest shower.   Its hype and probably clickbait. Do your viewing armed with reasonable expectations and you will be rewarded (unless its cloudy).   What Causes the Perseids? The Perseid meteor shower is really material left behind by Comet Swift-Tuttle. It passes through our part of the solar system every 133 years. As it travels, this icy dirtball leaves behind tiny grains of ice, dust, rock, and other debris, similar to a messy tourist scattering debris from an automobile. As Earth makes its trip around the Sun, it passes through this debris field with some spectacular results, which we know as the Perseids. As Earth moves through the stream — which can stretch across 14 million to 120 million kilometers of interplanetary space —   its gravity interacts with the particles and spreads the stream out. As the comet passes by, it releases new bursts of particles, constantly refreshing the supply of material that will eventually collide with Earths atmosphere. The stream changes constantly, and this affects future Perseid meteor shower events. Sometimes Earth passes through rather thick areas of the stream, and that results in a heavy meteor shower. Other times, it traverses a thin part of the stream, and we dont see quite so many meteors.   Although there are many meteor showers annually, such as the Leonids, Lyrids, and Geminids, to name a few, the Perseid shower is the most reliable, and can be very spectacular if conditions are right. How it looks depends on several factors — ranging from whether the Moon is nearby (and bright enough to wash out the view) — to what part of the stream Earth encounters. The stream is not uniformly thick with particles, so some years the supply of materials might be less than others. In any given year, observers see anywhere from 50 to 150 meteors an hour on average, increasing at times to around 400 to 1,000 per hour.   The Perseid meteor shower, like other meteor showers, is named after the constellation from which it appears to radiate:  Perseus  (named after a Greek mythological hero)  which is located near Cassiopeia, the Queen. This is also called the radiant, since that is the direction the meteors seem to travel from as they streak across the sky. How Do I View the Perseid Meteor Shower? Meteor showers are easier to view than many other astronomical objects or events. All you need is a fairly dark location and a blanket or lawn chair. Always make sure you have a jacket handy, even if you live in a warm weather climate. Viewing late at night and early in the morning can expose you to some chilly temperatures. It may be useful to have a star chart  to help you locate Perseus, and other constellations while you’re watching, but it’s not a necessity. The shower is active from mid-July each year  when Earth enters the outer edges of the Swift-Tuttle stream.  The best viewing time varies but is often between 2:00 and 4:00 a.m. around the 12th of August. The actual peak time ranges from the 9th to the 14th and then tapers off after that. For August 2017, the best viewing time is after midnight early in the morning of August 12th. There will be some interference from the Moon, which will be just past full. But, you should still be able to see the brightest ones. Also, start watching a few nights before and continue a few nights after; Perseids happen for nearly three weeks. Find a good, safe viewing area where you can get a clear view of the sky. Arrive early to set up, and  give yourself time to adjust your eyes to the darkness. Then, just sit (or lie) back, relax, and enjoy the show. Most of the meteors will appear to radiate from the constellation Perseus, and streak across the sky. As you gaze, make note of the colors of the meteors as they streak through the sky. If you see bolides (larger streaks), note how long they take to traverse the sky  and notice their colors, too. The Perseids can be a very rewarding observing experience for anybody — from younger children to experienced stargazers.   Edited and expanded by Carolyn Collins Petersen.

Economic Impact Of Tourism On Economic Impact On Tourism

Literature Review A summary of literature on economic impact of tourism has been depicted throughout this review to explore the methodologies used and their uses in estimating the economic impact of tourism. There is a need to conduct economic impact analysis of tourism – as tourism activity cannot be regarded as an isolated economic activity. A number of authors have contributed towards the area of EIA and have employed several methodologies covering input-output model, Keynesian multiplier model, social accounting matrix model and computable general equilibrium modelling The review search strategy was supplemented by making reference to existing literature reviews in the area of economic impact assessment (Reeves, 2002; Mazumder, Al-Amin†¦show more content†¦The findings of the study confirmed the cultural sector was a significant employer, and it highlighted differential earnings across the sector and  £5 billion was estimated to be generated through consumer expenditure (Reeves, 2002:9). In The Economic Importance of the Arts in Great Britain Myerscough (1988) demonstrated, through use of the multiplier, that direct spending on the arts led to spending in other sectors of the economy, which in turn enhanced wealth and job creation, and made cities appear more attractive to citizen and companies. The author points out some of the far-reaching impacts on the cultural sector and increased need for public funding. Policymakers have argued cultural industries can make an effective contribution to wealth creation, invisible exports and employment. Their potential for transforming many areas of existing practice, inspiring new producers, and for providing skills and competencies such as innovation, originality, creativity and problem-solving which could be effectively fostered for regional and local economies, was increasingly recognised (Reeves, 2002:10).

The Breast Screen Program Australia Samples †MyAssignmenthelp.com

Question: Discuss about the Breast Screen Program Australia. Answer: Introduction Breast screen Australia can be defined as the breast cancer screening program. The Breast screen Australia programs objective is to detect unsuspected breast cancer in women at an early stage by the process of screening mammography. The aim of the program is to reduce the number of deaths and illness caused by breast cancer. The aforementioned program entitles women who are aged 40 and above to free screening mammography every two years(Welch, Prorok, OMalley, Kramer, 2016). It has been estimated that breast cancer has affected a majority of women population in Australia and has been identified to be the most common type of cancer which has affected Australian women. According to the results of a survey, it has been identified that in the year 2013,9581 women in the age group of 50-74 in Australia had been diagnosed with invasive breast cancer. Breast cancer has been identified as the single most common cause of death of Australian WOMEN after lung cancer. The program, Breast Screen Australia has been well received by the women of Australia and more than fifty percent of the female population in Australia has actively participated to get them screened. However, it can be said that the program has not had much effect on the indigenous population. Participation of Aboriginal Australians and Torres Strait islanders in the program, Breast Screen Australia has been significantly low(Oeffinger, et al., 2015). Discussion: Breast Cancer Breast Cancer can be defined as one of the most common types of cancer which originates in the ducts of as well as in the lobules. However, in rare instances breast cancer can also originate in the in the connective tissue which connects the ducts and the lobules of the breast. It can be said that breast cancer happens to be the most common form of cancer affecting an average of one out of four women. However, the prevalence of the disease is more common in developed countries as compared to developing nations(Myers, et al., 2015). It can be said that according to the reports of Australian Institute of Health and Welfare that Breast cancer can be considered to the most common form cancer and which constitutes 28% of the types of cancer affecting women. Occurrence of Breast Cancer has been identified in 124 women per 10000 women in Australia(Zajac, 2016). The factors that cause Breast Cancer are not known however, many risk factors that aim breast cancer in women have been identified. One of the most prominent factors that causes breast cancer has been identified to be age. Occurrences of breast cancer are most common in women belonging to the age group of over 50. Hormonal and reproductive factors are also contributing causes of breast cancer(Freimanis Yacobozzi, 2014). Some of these factors include: not having given birth to children, giving birth at old age, menopause at an old age. Hormone replacement therapy and oral contraception have also been identified to increase a small risk of breast cancer(Mathew Sibbering, 2018). It can be stated that a family history of Breast can cancer can increase a womans chances of developing the same, however according to the report provided by Breast Cancer Australia 2015 it can be said that 8 out of 9 women who develop breast cancer do not have a mother or sister who is a victim of breast canc er. According to the research done by(trove.nla.gov.au, 2018)it can be sated that family history as a contributory factor of Cancer in Australia can be classified in three categories: Slight or average risk- 95 percent of the women population belongs in this category. The women in this category have no family history or a very weak family history of cancer. It can be said that nine out of ten women in this category are less likely to develop cancer. Moderate Risk- Less than four percent of the female population belongs in this category. Women in this category have a moderate risk of developing breast cancer due to a strong family history. Examples of such family history include first degree relatives on one side of the family. Potential High Risk- Less than one percent of the women fall in this category. Women who have a strong family history which includes first and second degree relatives on either side of the family and additional factors on the same side of the family. Impacts of Breast Screen Australia Breast Screening Detects Breast Cancer early It can be stated that free breast screening is available to the women population in Australia belonging to the age group of 50-74 years age group by the program Breast Screening Australia. The women population who belong to the age group of 40-49 are eligible to get tem screened, however they are not actively targeted(DeSantis, Ma, Bryan, Jemal, 2014). It can be stated that like other population based screening programs, Breast Screen Australia aims to detect unsuspected breast cancers which would have otherwise gone unnoticed. The programs aims to detect breast cancer by the use of screening mammograms and therefore reduce morbidity in women. Breast cancer in women allows them to access diagnostic and treatment services at an early stage. Detection of breast cancer at an early stage can even be cured with the latest treatment services available. In the process of screening mammography, radiologists review the images of each of the breast to detect any unsuspected or suspicious characteristics which require further inspection. The process of screening mammography is not however diagnostic in nature. Screening mammography has been found to be more effective in older women as their breasts become less dense after menopause. It is also one of the main reasons why women in the age group of over 50 are more prone to develop breast cance r. Such process of mammographic screening is not however considered to be effective in women who are younger than 40. This is because the breast tissue in younger women are more dense and therefore it becomes difficult to identify any development of cancerous cells. Breast Screening mammography decreases morbidity and morality It can be said according to (NBOCC 2009) that lower morbidity from breast cancer can be achieved by detection of the cancer at an early stage as it gives the patients the options to choose from the different treatment options available. As provided by the reports of NBOCC 2009, it can be stated that the program Breast Screen Australia has detected almost 59 percentage of the breast cancer occurrences in women. Only 28% of the all the occurrences of breast cancer has been detected outside the program. Treatment of breast cancers detected by Breast Screen Australia is done mostly by breast conserving surgery which is closely associated with decreased morbidity. Breast Screening effectively benefits mortality as detection of breast cancer at an early stage has been proved to increase survival rates among victims of cancer(Uicc.org., 2018). It had been estimated that effective breast screening programs has reduced the rates of mortality rates among women by 21 28% (Cancerscreening.gov.au, 2018). It can be said in accordance with the reports of International Agency for Research on Cancer 2015 that that mortality rates has been significantly reduced in Australia due to Screening Mammography. These benefits of mortality have been reflected on the women who have been targeted by the program Breast Screen Australia. Screening and re screening Mammography which is X-ray of the breast is the test that is used in breast screening. The active participation of women in the program Breast Screen Australia is an indicator of the programs performance. Women in Australia have also recognized the need to get them screened as they have realized the effects of breast screening to reduce morbidity and mortality. Participation of women in the program are measured over a time period of two years which is aligned with the two year recommend screening interval of the program. It can be stated that the percentage of women who return for a re- screening after the two year interval is also measured. However according to Breast Screen Australia program although the recommended screening interval is 24 months( two years), it is estimated that twenty seven months is a reasonable time period which is required to assess any new developments and women to respond to invitation to respond to such screening process(aihw.gov.au, 2018). Conclusion Thus to conclude it can be said that breast cancer is the most common form of cancer that affects women all over the world. Occurrences of breast cancer are common in women belong in the age group of 50 and above. Breast Cancer has been identified as the most common cause of death of female population in Australia after lung cancer. The program Breast Screen Australia has been initiated by the government of Australia to do mammography screening of women in every two years to detect any suspicious and unnoticed growth of cancerous cells in the mammary glands. The process however, is not diagnostic. Breast screen Australia has been well received by the majority of the population and the evidence of the same can be exhibited by the high rates of participation. Bibliography aihw.gov.au.
