Paintball The Safe Sport Essays - Paintball, Outdoor Recreation
Paintball: The Safe Sport So, your son, daughter, or husband is begging for your okay to buy the latest paintball equipment. It's surprising, but after only one or two trips to the paintball field, folks just get hooked! While you'd like to share their enthusiasm for the sport and give your much needed go ahead, you are concerned with your loved ones shooting paintballs at other players and being shot at. Don't feel like you're alone. These are common and serious concerns that deserve a thoughtful response. The following paragraphs will hopefully explain why our sport is the fastest growing sport in the world and that it doesn't have anything to do with people hurting one another. Paintball has had an astounding safety record. Medical and insurance statistics show that paintball is safer than bowling! This is a strong testimony to the game and they players who play it. Paintball is a safe sport as long as rules are followed. Insurance statistics also show that paintball is much safer than golf, jogging, downhill skiing, snow boarding, tennis, swimming and many other more common sports. Safety is highly stressed at most fields. The majority of fields require goggles be worn at all times unless in designated areas. In addition to this fields also require that barrel plugs (plastic inserts that prevent projectiles from leaving your gun's barrel) be used while players are in certain areas. Ignoring safety is a good way to get yourself ejected from a field. Men and women of all ages and life-styles play paintball in over 30 countries. From schoolteachers or high school students, professionals or technicians, all paintball players share a love for adventure and a strong competitive team spirit. Paintball is similar to the childhood games of tag and hide and seek, but much more challenging and sophisticated. There are various game formats. Usually, a group of players will divide into two teams to play capture the flag. The number of players on a team varies from four or five players, to as many as 100 players on each side, limited only by the size of the playing field. The object of the game is to capture the other team's flag while defending your own flag station. Players compete to eliminate opposing players by tagging them with a paintball expelled from an airgun. Games usually have a time limit of 20 to 45 minutes. Between 10 - 15 games are played during one day. Between games, players may check their equipment, reload paintballs or have a snack and share stories about the thrills of victory and the usually funny agonies of defeat. Win or lose, everyone has a great time! A paintball is a round, dime-sized gelatin capsule with colored liquid inside. Paintballs are similar to large round vitamin capsules or bath oil beads. The liquid is non-toxic, non-caustic, water-soluble, and biodegradable. It rinses out of clothing and off skin with mild soap and water. Paintballs come in a rainbow of colors. When a paintball tags a player, the gelatin ball opens and the liquid leaves a paint mark. A player who is marked is eliminated from the game. Paintball guns come in a variety of styles. Some are small stock pistols, powered by small 12-gram CO2 cartridges that need to be changed after 15 to 25 shots. Other paintball guns are rifle-like, with shoulder stocks and longer barrels. These are powered by larger, refillable CO2 cylinders that supply hundreds of shots. Some paintball guns are pump-actions. Each time you shoot, you must first cock the paintball gun by using a pump. Other paintball guns are semi-automatic, which re-cock automatically. Just squeeze the trigger! Paintballs won't hit hard enough to cause an injury as long as proper safety procedures are followed. Protective covering with multiple layers of clothing is recommended. To protect their eyes, all players must always wear approved-for-paintball goggles in every area where shooting is allowed, even at the target range. Barrel plugs are required anywhere off the playing field. Professional referees on the playing field control the games, enforce the rules of fair play, and monitor safety rules. Most paintball fields have a staff of trained referees that allows them to conduct several games simultaneously. Paintball is a sport where women and

CLK-1 Mutants and Aging essays
CLK-1 Mutants and Aging essays CLK-1 MUTANTS AND THEIR ROLE IN AGING Aging is a fact of life, it can be scary to watch yourself and those around you grow old. The idea of a mythical fountain of youth has enticed adventures from around the world for centuries. The idea has enchanted me since I had a conversation with my grandmother in which she stressed that the only thing that mattered in life at her age was health. So what causes the body to wither with age and is there anything that we can do to prolong the inevitable? There are many different causes of aging, all of which result in a decline in the bodies ability to function properly. Recent research has come up with several different ways to combat some of the major causes of the physical degeneration that is associated with growing old. Studies of long-lived mutant worms, yeast, and mice are useful tools in examining the processes that are involved in limiting/expanding the life span of organisms. Some of the most intriguing gene mutations known to increase life span are the daf-2, clk-1, and isp-1 which deal with the regulation and control of Reactive Oxygen Species (ROS). ROSs consist of molecules such as superoxide, hydrogen peroxide, and hydroxyl radicals, which cause extensive damage to biological macromolecules. This leads not only to many serious diseases, but also plays an important role in aging. The main source of ROS is in the mitochondria, where superoxide is produced during the process of electron transport and can give rise to other reactive species through reactions with detoxifying enzymes (1). More specifically is the production of ROS involved in processes dealing with the reduction and subsequent oxidation of the redox-active lipid Ubiquinone (UQ). Understanding the role that UQ plays in the Electron Transport Chain (ETC) helps to understand the complexity of ROS formation. The ETC consists of fou ...

Analyze and discuss the issues of music and authenticity in relation Essay - 1
Analyze and discuss the issues of music and authenticity in relation to two or three of the films - Essay Example In this movie, the audiovisual uses multiple communication channels including mainly: image, sound, verbal language (written or spoken). The sound acts directly on the senses of viewers, much more than the image and the verb. Its impact is much more subtle: à an image or a word provide immediate intellectual meaning and cause reactions largely conscious. Instead, this movie is largely beyond an intellectual analysis because its benchmarks are not palpable. The viewer receives it and reacts subjectively. The sound in this movie, à more than any other carrier, is handling affective and semantics means of an audiovisual message: images and words. There is a connection between a musical vocabulary, referring to aesthetic and sensory phenomena, and the vocabulary of everyday life, covering an ethical and intellectual reality of this time. Reconciling these two semantic universe can only afford to develop a specific speech and the music gives the tone to the speech in this movie, the m usic is in very tight collaboration with the sentences, with the environment, with the epoch. In the world of entertainment, the design of a musical message partially escapes its own creators: the intuition and experience offset the lack of a grammar of the language of music. The effectiveness of the message comes with a simple observation: "it works" or "it does not workâ⬠...

Analyze the statements of each speaker. What does each statement imply Essay
Analyze the statements of each speaker. What does each statement imply regarding their views on the following legal philosophica - Essay Example George Wallace was the 45th Governor of Alabama and he was strongly in favor of segregation laws. He held opposite opinions from Luther King Jr. on human rights and believed that it was right for white and colored men to be treated differently. His opinion on civil movements was also not pleasing for civil rights activist. He called for an end to these movements. Kingââ¬â¢s views on Legal Philosophical Issues Natural law is the law that is based on human inclination or nature (Rothbard, M. 2011). Positive laws are manmade laws that are based on the fact that human beings are not inherently moral or rational so laws are required to govern them. Martin Luther King considered natural law to be more legitimate than positive laws. King considered the positive laws of segregation to be incoherent with natural law of freedom and justice. He said ââ¬Å"We can never be satisfied as long as our children are stripped of their self-hood and robbed of their dignity by signs stating: ââ¬ËFo r Whites Only.ââ¬â¢Ã¢â¬ (Luther King Jr.). Segregation was supported by law and King argued against it because he thought it was against the natural laws of freedom. Luther King Jr. was of the opinion of St. Augustine that ââ¬Ëunjust law is no lawââ¬â¢ (MacDonald Jr. 2010). ... Law should be used to promote the common good as argued by King. He believed that it was our duty to follow the just laws. Just laws promote the common good among people by listening to the all groups of the society. He says in his speech ââ¬Å"Now is the time to rise from the dark and desolate valley of segregation to the sunlit path of racial justiceâ⬠(Luther King Jr.). So he argues that laws should be changed. When he argues that laws should be changed he must believe that laws can be used to promote common good of the people. Martin Luther King Jr. believed in the non violent ways of protest. He was inspired by Gandhi and his philosophy of non violence. He believed that violence is not justified even if it is done to achieve a just claim. He said specifically ââ¬Å"In the process of gaining our rightful place, we must not be guilty of wrongful deedsâ⬠(Luther King Jr.). This clearly explains his non violent ideas. He strongly believed that harm done to people even in the course of protest for a just cause is not justified. The legal philosophy of King was to achieve the aims through peaceful protests and not physical violence. King viewed the role of autonomy to be great in determining aims of law. Autonomy was promised by the ancestors of America but this was not given to the black Americans. In his opinion aims of law were to promote autonomy but later on the society developed its own biases and prejudices. State intervention is argued by Stuart Mill but only in cases where a person inflicts harm or danger to the society (Dogan, A. 2006). King sees paternalism as undesirable as it hinders in achieving the aim of law and that is to promote freedom. Morality plays a role in determining aims of law according to Luther King Jr. The aims

The Contemporary American Dream Essay Example | Topics and Well Written Essays - 1000 words
The Contemporary American Dream - Essay Example The development of suburbia ââ¬Ëstartsââ¬â¢ with a farewell to Rosie Riveter as transition from World War II to the suburbs of the 1950s. The female factory worker needed to be sucked back into the home to make way in the factories for the returning soldiers. This is brilliantly portrayed through the innovation of the television set, which played a large role in reinforcing to women the concept that their proper roles were those of wife and mother. Rosie is sucked into the screen, losing her wrench while the well-manicured lawns and white orderly house fronts of the suburbs can be seen below her as she is overwhelmed by the messages of TV advertisements and popular shows such as Leave it to Beaver. To be sure this point isnââ¬â¢t lost by the mural viewer, the stereotypical white suburban family can be seen standing behind the television. The rows of suburban houses are divided in the middle by a column of moving trucks, presumably bringing more blonde, blue-eyed suburban per fect families away from the distant city to the white-washed neighborhoods. Finally, a deep ditch separates these perfect neighborhoods from the poor, rural black people that pass by heading in the opposite direction in broken down cars and on bare feet heading into the city. They are allowed to look, but not to stop or stay. While the American Dream is being defined for and realized by the white people, the only hope of achieving it for the black people is to head into the inner city slums in the hopes of finding work.

The issue of global food security in the future
The issue of global food security in the future Introduction Food is a necessity for life, yet millions of people every day go without it, due to a lack of global food security. Food has been used for millenniums to bring people together, yet there are people in poverty every day that donââ¬â¢t know where their next meal is coming from. With the population steadily growing, now is a more important time than ever to eradicate hunger around the world. Description of the issue With the population set to have increased by more than 35% (Foley, 2014) in 2050, we will be faced with the reality of having to feed nine billion people. For this to be achievable, crop production would need to double, as it would have to significantly outpace population growth. With millions currently starving around the world, global food security doesnââ¬â¢t seem achievable. However, if we work together and are guided by the principles of human flourishing, the agriculture industry should be able to grow alongside our population, eventually resulting in food security for all. Reasons why this issue is one associated with social justice The United Nations (un.org, n.d.) defines social justice as ââ¬Å"an underlying principle for peaceful and prosperous coexistence within and among nations. We uphold the principles of social justice when we promote gender equality or the rights of indigenous peoples and migrants. We advance social justice when we remove barriers that people face because of gender, age, race, ethnicity, religion, culture or disabilityâ⬠. Food stability is an issue associated with social justice due to the millions of people starving around the world every day because of a lack of access to food, or an inability to purchase it. Food is a necessity to live, and therefore should be available to all, regardless of geographic location, economic status, or any other disability. Stakeholders involved in this issue and analysis of their perspectives Scientific research and development bodies play a vital role in the issue of food security going forward. Global partnerships such as CGIAR work towards research for agricultural production in the developing world. Their aim is to ââ¬Å"identify significant global development problems that science can help solve; collect and organize knowledge related to these development problems; develop research programs to fill the knowledge gaps to solve these development problems; catalyze and lead putting research into practice, and policies and institutions into place, to solve these development problems; lead monitoring and evaluation, share the lessons we learn and best practices we discover; conserve, evaluate and share genetic diversity; and strengthen skills and knowledge in agricultural research for development around the worldâ⬠(CGIAR, n.d.). Through their aims, they hope to achieve four main goals: reduce rural poverty, improve food security, improve nutrition and health, and have sustainably managed natural resources. CGIAR believe that science can make radical changes to the current issue of food security, and it has been cited that ââ¬Å"one dollar invested in CGIAR research results in about nine dollars in increased productivity in developing nationsâ⬠(CGIAR, n.d.). Partnerships and bodies such as CGIAR want the current situation in regards to food security to change, as they realized that the present condition is neither sustainable, nor fair, and while it may not be easily fixed, scientific breakthroughs make the issue of food security appear to be one that can be solved. Farmers make up for 60% of the worlds population (apcentral.collegeboard.com, n.d.), yet they are constantly under threat from large corporations buying up their land. Many countries also face the issue of how to ensure increased efficiency in farming the land we already have, as Foley (2014) states ââ¬Å"most of the land cleared for agriculture in the tropics does not contribute much to the worldââ¬â¢s food security but is instead used to produce cattle, soybeans for livestock, timber, and palm oil. Avoiding further deforestation must be a top priority.â⬠There are currently ââ¬Å"yield gapsâ⬠between existing production levels and those possible in areas such as Africa, Latin America, and Eastern Europe. ââ¬Å"Using high-tech, precision farming systems, as well as approaches borrowed from organic farming, we could boost yields in these places several times overâ⬠(Foley, 2014), which is important in providing more food to the world, while not increasing the size of the agricultural footprint. If farmers were able to invest in these technologies, such as subsurface drip irrigation, cover crops, and mulches, there may be a high upfront cost, but they would be producing more, which would lead to them increasing their profit once the produce is sold. With a higher profit, these small farmers may be able to better stand their ground against large corporations. These methods of organic farming are also more environmentally friendly, which is important as issues such as climate change have a large impact on agriculture. While it is often believed that small farmers are better, putting more heart and soul into what they do, there is still a role for multinational agribusinesses in the road towards food security. Many of these businesses, such as Monsanto, have been working to develop products, and methods to help farmers grow more on the land they have. Agribusinesses work closely with the scientific research and development bodies, as they are often the largest investors. Companies, like Monsanto, have spent millions on developing agricultural innovations in key areas, such as breeding, where they select the more desirable traits from existing plants; biotechnology, where they add these beneficial traits into the DNA of another plant; integrated farming systems (IFS), which helps farmers utilise the resources they have for maximum yield, while reducing the amount of wasted resources; and chemistry, where studies are done to minimise environmental impact of herbicides, while still protecting crops from pests (Monsanto.com, n.d.). Companies like Monsanto recognise that they need to invest further in agriculture, as the lack of food security means that they are being badly perceived, and largely blamed, due to their for-profit nature, and their use of terminator genes in their seeds, leaving a heavy financial burden on farmers, as they are unable to use the seeds again for next year. Many foods are already genetically modified, but Monsantoââ¬â¢s lack of ethical boundaries in doing so (such as the terminator gene to boost their profits, and crops that will only work in conjunction with their other products to gain and to capture a captive market), has resulted in public outcry against the corporation worldwide. Protest against the company has come from all corners of the globe, not just the United States, and Australia, as it is the farmers in the developing world that are most effected. These sort of issues need to be addressed if we are to produce enough food for the growing population, as all farmland ne eds to be utilised efficiently, not just those farmers who can afford it. Analysis of the issue in relation to the common good and the principles of human flourishing The common good can be defined as benefiting everybody in the world. Human flourishing comes from the Greek word eudemonia, which is a core idea to Aristotelian philosophy. It promotes the idea that by working together, and finding meaning in our lives, we will flourish as a whole. The principles of human flourishing guide us in ways we can work together and find the meaning we need to achieve this. Global food security is an issue affecting the word, where the current injustice of the many people left malnourished needs to be responded to at a global level. The common good urges us to work together in collaboration to take responsibility for those around us, and pursue conditions in which we can achieve a life that is good for all, not just a majority. In order to achieve this, we must fight against injustices, such as Monsantoââ¬â¢s mistreatment of small farmers, at both local and global levels. Charity organizations can only do so much to help, and promoting the common good often challenges many current social values, and social structures that allow these injustices to take place without government interference. The main principles of human flourishing relating to the issue of food security is: the dignity of the human person, preferential option for the poor, stewardship of creation, and solidarity. The dignity of the human person is an important principle in food security, as it promotes the rights of those who may not be able to bring attention to their needs themselves. Avocation is important, as it is often those who need the most help that are unable to ask for it. Many small farmers in Africa, Latin America, and Eastern Europe are struggling to produce enough food, not just for global consumption, but also for themselves. Due to their nature as small farmers and not multination businesses, their voice isnââ¬â¢t often heard when speaking out against the problems in the agriculture industry worldwide, such as Monsantoââ¬â¢s use of terminator genes in their seeds, which further disadvantages the poor. The poor cannot afford to keep buying new seeds every season, often relying on the seeds gathered from last season to replant. This keeps costs low for small farmers, and allows them to increase their profit margin. Monsantoââ¬â¢s use of the terminator gene means that the seeds can only be used once, and often only used when combined with other Monsanto products. Monsanto has been suffering public backlash over these issues for years as a result. A preferential option for the poor would see governments and not-for-profit organizations providing resources, such as non-genetically modified seed, or fertilizer, to these smaller farmers, allowing them to kick start their production. This would utilize the land already cleared for farming, and reduce environmental impact as well. Stewardship of creation is the principle of looking after the planet. Agriculture has already lead to ââ¬Å"an area roughly the size of South Americaâ⬠(Foley, 2014) being cleared for crops, and even more land ââ¬Å"roughly the size of Africaâ⬠(Foley, 2014) has been cleared as pastureland for livestock. This has resulted in the loss of whole ecosystems, and is not sustainable. Particularly with the rise of global warming, deforestation is not an option. In order for us to maintain the planet for future generations, we must use the land we have available more efficiently so we can still produce enough to provide food security. It is our responsibility to care for the planet, so it can care for us in return. Solidarity is the principle that it is our responsibility to care for each other across racial, economic, cultural, national, and ideological differences, while promoting rights for every person. In order to accommodate their needs, we must first recognize that everybody is different; while there are people starving in developing nations around the world, there are also many homeless and hungry people right here in Sydney that require our help. Their needs may differ greatly, despite their common problem of a shortage of food. Solidarity is recognizing those abroad, as well as those at home, and working towards global food security together. A proposed resolution for realising the common good In order to reach global food security by 2050, we must take steps now to be able to achieve the common good. With scientific developments, we are able to better develop the land we already have available, allowing us to produce more without further damaging the environment. By utilising high-tech farming systems, we can work towards reducing the yield gaps we currently have, boosting the output from these areas, as well as providing a much more reliable source of income to these small farmers. With the scientific research and developments that have taken, and are currently taking place, small farmers are able to better understand the best ways to work their land, not only to create a higher yield, but also to save and use resources more efficiently. This helps the environment, as up to 70% of water is used in agriculture, and also saves the small farmers money. A big part of realising the common good is understanding our part in it on an individual scale as well. We may not be scientists or farmers, but by participating in actively changing our diet, we, too, can help global food security be achievable by 2050. As Foley (2014) states, ââ¬Å"for every 100 calories of grain we feed animals, we get only about 40 new calories of milk, 22 calories of eggs, 12 of chicken, 10 of pork, or 3 of beef. Finding more efficient ways to grow meat and shifting to less meat-intensive dietsââ¬âeven just switching from grain-fed beef to meats like chicken, pork, or pasture-raised beefââ¬âcould free up substantial amounts of food across the worldâ⬠. Conclusion Global food security is an issue that affects us all. Agriculture is one of the oldest and largest industries in the world, but it still has a long way to go before it is able to cater for the growing population. However, the issue has been recognised, and together, we are working towards eliminating hunger, and providing food security by 2050.

Wind Power Versus Hydroelectric Power: Which is Better for the Environ
The energy produced and created by using the kinetic energy which comes from the wind naturally is known as the wind power. Wind power is the technology to catch the energy gained with movement, kinetic energy, and change this energy into electrical power which is useful in many places, such as households throughout the nation. Wind power can be produced by using a device called wind electric turbine. Several huge blades, about 30 feet long, are placed on each wind turbine. While wind passes through the blades, the wind with kinetic energy makes the blades to turn. The movement of blades makes a shaft inside the turbine to be in motion as well with the same velocity of the blades. This work turns the kinetic energy into rotational energy which will be stored into a generator located at the bottom of the turbine. After the rotational energy is kept in the generator, this energy is changed into electrical energy. Finally, the electrical energy is removed into the electrical plant for s torage by the power lines until the communities are in need of energy. Referring the process, systems, structures, and equipment that help with conversion between kinetic energy and the pressure energy of flowing water into electrical energy is known as hydroelectric power. Hydroelectric skill became a leading force of development in the living standard during the electrical age. During the Industrial Revolution, hydro mechanical technology was developed based on simple water wheels from ancient times. The method, conversion of flowing water to electricity, is known as very environmental process because no waste is created during energy generation. Many hydroelectric power plants depend on the same similar basic rule as a historical water wheel. Howe... ...tion or loss of fish habitat, and inundation of wildlife habitat and land in some cases. There could be changes in stream water quality and reservoir in some cases as well. Although both wind power and hydroelectric power have some disadvantages, I believe wind power is more useful than hydroelectric power because wind power will not produce any pollutants while hydroelectric power produces few minimal pollution. Also, hydroelectric power plant needs high investment costs, so this device cannot be built by the developing countries. On the other hand, the cost of wind power is decreasing because of better generation techniques and technology improvements, so the wind power will become increasingly feasible as a main source of mechanical power and electricity. I believe the device that can be built by everyone is more likely to reduce global warming problems faster.
