Waste Disposal and Green Intelligence Dissertation

Waste Disposal and Green Intelligence - Dissertation Example The government should play a crucial role in ensuring that citizens are made aware of the best and most convenient ways of managing waste. Waste recycling is one of the interventions that most governments especially in first-world countries have taken to deal with waste management. For example, the U.S government has carried out campaigns to sensitize its citizens on the importance of recycling materials such as plastics, paper, and glass. In as far as land filling is concerned; the government advices that the dug up surfaces should have bottom liners to collect any water that may contain hazardous chemicals. This way no toxic water flows into the ecosystem. Concerning disposal of wastes into water bodies, the U.S government directs that industrial wastes be deactivated before being released into water bodies.The main goal of green intelligence is to provide the general public with information concerning the dangers they are exposed to as a result of poor waste management. This invol ves using market-oriented approaches to ensure environmental sustainability and conservation of natural resources .Green intelligence strategizes to achieve its goal by urging the private sector and the government to avail necessary information to the public. This is because the government and private sector seem to be colluding to hide trivial information from the public on hazardous substances and poor waste management. According to Wargo, chemical manufacturers are very crucial in ensuring a safe environment and a healthy general public.

Muscular Disorders Case Report Essay Example for Free

Muscular Disorders Case Report Essay A mother presents with her 13 y/o son with a history of frequent falls, difficulty getting up from a lying or sitting position, trouble jumping, large calf muscles and poor grades in school. Based on the description and symptoms given, the likely diagnosis would be Duchenne’s muscular dystrophy, or DMD; although DMD and its symptoms tend to show up at an earlier age but not always. This type of muscular dystrophy is the most common and severe form of the dystrophinopathic diseases. Dystrophinopathic diseases are muscular dystrophies that are of a genetic nature caused by a deficiency in the protein dystrophin. This protein is vital to muscle function and contraction. In the case of DMD, there is a mutation in the gene, called the DMD gene, responsible for producing dystrophin causing a deficiency. This gene mutation is X-linked recessive and is inherited. This means that females in the family carry the gene mutation and can pass is on to their offspring male or female, but it is expressed in the males. DMD is usually diagnosed when a young boy shows signs of muscle weakness and there is a family history of the disease. Per Genome (2010), â€Å"a muscle biopsy for dystrophin studies can also be done to look for abnormal levels of dystrophin in the muscle. † Genome (2010), also states that â€Å"genetic testing on a blood sample for changes in the DMD gene can help establish the diagnosis of Duchenne’s muscular dystrophy without performing a muscle biopsy. † For most individuals, a combination of these testing methods is used to confirm a diagnosis of DMD. There is no known cure for DMD. Treatment involves treating the symptoms and keeping the patient as comfortable as possible. Medline (2012) says that â€Å"steroid drugs can slow the loss of muscle strength and may be started when the child is diagnosed or when muscle strength begins to decline. † Other drugs, such as Albuterol, can be used to control breathing problems that occur in the later stages of the disease and drugs to help with heart functions are prescribed to help control any cardio symptoms that may be present. The prognosis for individuals with DMD is bleak; it is a rapidly progressive disease and patients with DMD usually surrender to the disease or complications from it in their 20’s or 30’s, sometimes even earlier. I grew up with a family next door to me in which the two oldest boys had DMD. The disease eventually took both of their lives. The oldest boy did live long enough to graduate from high school but the younger of the two died from complications when he was 16. It was horrible for the family to stand by and watch their sons slowly decline and eventually die. This disease continued to plague their lives when the daughters passed it on to their boys and probably still plagues them today. There have been great strides in the field of research in regards to DMD but as of yet no cure has been found. Hopefully one day, there will be a cure for this devastating, debilitating disease and no more families will be forced to watch their children die right before their eyes.

Water Rocket Dominant Modification Factors

Water Rocket Dominant Modification Factors Bryan Conston Water rockets tell the story of a wet launching period: the liftoff, height climax (apogee), and the momentous landing all are viewed at an observer’s glance. Of course, some â€Å"stories† come out to be more surprising and startling than others because of the ingredients. In a perfect physics world, about any rocket could soar to its maximum potential. Truly this is not the case for the real world, where wind and weather could mean the difference in a water-limited rocket’s success or failure. Water may leak out of the rocket. The bottle may explode suddenly due to hot air or the amount of pressure fixed in its frame. Though anything can hinder a rocket from it’s planned altitude, there are ways through applying water rocket knowledge to counteract it for good: adding modifications to the rocket. As the question was answered about whether modifications to a two-liter bottle would be beneficial to flight altitude—it is absolutely necessary—the real question springs forward: â€Å"What modifications can we use to a plastic bottle?† There are countless variables regarding water rocket propulsion, such as how much water should be applied. Necessity is the mother of invention for designing water rockets, so with basic adjustments to the bottle rocket, testing the improvement would be much easier. Still, though, some modifications may hurt the condition of the rocket. For several pieces of a water rocket design, nifty and thoroughly examined modifications of fins, nozzles, and the bottle itself will be a key factor in its success. In the livelihood of summer, water makes way for an awe-inspiring experience: water rocket launching. Feeding the excitement of several teachers, children, and parents, water rockets fascinate schools and colleges with its handy demonstration of physics. The process of constructing a water rocket requires a little more than a bottle, nozzle fins, and a creative mindset. However, most participating in the mechanism would hope to watch the rockets as they â€Å"send them skyward†, as water rocket enthusiast Barbara Wolcott encourages (screen 1). How does this specific journey of the rocket—its propulsion—take place? There are always things to consider about constructing a rocket, for with everything there is ways to improve the rocket’s condition. The pounds per square inch (PSI) should be a level pressure for the water to cooperate with Newton’s third law of opposite reaction, and the water needs to maintain a flow with the nozzleand so on. The launch depends on several variables and add-ons that would enhance the flight experience, such as nose cones. The most dominant components of the rocket launcher—the nozzles, fins, and bottle—act as a major collective force for influencing the rocket’s successful propulsion, protection, and flight height. One of the most dominant modifications that should be made to all rockets is the nozzle. Brad Calvert claims that a good nozzle produces rapid but brief acceleration, at times lasting â€Å"only a few hundredths of a second.† (Calvert 5). A nozzle is simply a mechanical device used for controlling the fluid of the water rocket to allow it to build launching energy. While we may need fins, a durable bottle, and a dependable launcher, a rocket without a nozzle is one that will cause excessive errors like leakages. Thrust, the rocket’s force of action between the water and the bottle, is generated primarily by the nozzle. Truly, the big factor is the nozzle type. Restricted nozzles provide longer flight duration, while an open neck nozzle allows it nearly any time to pressurize, thus creating a problem for some launching tubes.. Also, nozzles depend on length and diameter. For instance, a full bore bottle is the standard neck opening of a PET bottle that is 22 mm long. Oth er modified nozzles include a Gardena nozzle with quick connectors or a Maxi-Flo nozzle with a large aperture. With these nozzles, the propulsion depends on the nozzle size: larger nozzles run the risk of leakage, thus weakening any chance of a high altitude. A modified nozzle is an excellent start towards a high-quality rocket. Even a bare bottle can launch off, but countless avenues of error could easily tamper the flight as a whole. This because rockets follow the rules of aerodynamic stability. According to Brad Calvert, the stability of the water rocket depends on the next dominant factor: fins. With overly restricted nozzles, larger fins at the rocket’s rear â€Å"are required to counteract the turning forces created at the front† (Calvert 6). Without fins, the rocket cannot balance it’s weight end to end, ruining any chance at a successful air travel. Moreover, if the fins are to be the power of stability, then they must be used correctly. Once the fins’ drag is minimized, they do all the necessary flight work by giving the rocket a nice, straight flight (often the flight will fall nose down as well). Fins make for the most important modification as far as safety goes. Without them, the rocket could ricochet somewhere and cause bodily injury to bystanders. Fins come in many sizes and shapes, and light tape works great as an adhesive. The ultimate goal of fin construction is minimizing the drag they create by keeping them small and thin. Manilla folders, soft cardboard, and other sturdy materials would work for fins effectively. A cylindrical fin may be â€Å"the easiest way to achieve stability with a restricted nozzle rocket† (Calvert 7). Truly, the fins embody a powerhouse for the stability and convenience of a bottle rocket. The classification of the bottle is critical to the success of the flight also: determining the brand, weight, and dimensions play collectively among other factors to produce the greatest apogee. As water forces out of the rear, the rocket’s weight slowly decreases as a function of time. The air shoving the water forces both the water and air outside the nozzle and creates a force that is equal in magnitude but opposite in direction, propelling the rocket upwards. This would not work effectively without an evaluation of the weight. Adding weight should be a caution—the lower the rocket weight with a constant water supply, the better launch. Extra mass should be attached to precise areas (such as fins should be placed lower on a larger rocket) for a balanced center of mass. Lightweight adhesives should be applied, but no hot glue should be used as it rips through and softens the bottle’s plastic frame. Using additional water should be a concern as well.. As Leo Singleton put it in his Bottle Rocket Handbook, â€Å"water is thrust, but it also adds excess weight† (Singleton 16-17). Balancing between thrust and weight is the best option. Usually 50% of the rocket should be filled with water, regardless of dimensions. Most people would of course use a two liter bottle for a water rocket base. This brings a higher concern for the fins’ shape. A two liter bottle has a relatively small distance end to end but a relatively large diameter compared to other successful rocket bottles. It is often said that long and thin water rockets â€Å"are easier to make stable† than â€Å"short and fat ones† (Water- Rockets Science for Hobbyist, Students, and Teachers of All Ages 1). This would be explained through several simulations showing a trend in rocket length and apogee, with increasing length without other modifications. Usually, the water rocket length will be manpower for the flight height, bringing positive correlation to the rocket’s trajectory. Also, the bottle’s brand would need to be carefully observed. Several experiments from multiple expert rocket launchers, including research done at college sites, yield that generic bottles cause more excessive leaking than brand name bottles. Leakage greatly reduces flight command, and bottles like Dr. Thunder and Mountain Lightning were shown to leak heaps of water (sometimes to its entirety) due to a larger nozzle opening. It’s best to use bottles that are made to contain carbonated drinks, for other bottles are not made to cope with the pressure used. Broken bottles should never be used. They are easier to explode randomly, so making sure the bottle is firm to the touch and durable is a sure way to increase safety to launching. Undoubtedly, the main factors that would make or break a water rocket’s success would be the fins, the nozzle, and the bottle type. The fins act as a buffer for any unstableness and lower the chances of a crash-worthy bottle. Even more, the nozzle plays the role of controlling the ignition of the rocket. The dominator of the rocket—its bottle frame—is the basis for the concept of water rocket launching. For several water rocket enthusiasts, starting with these modifications would make the best of any experiment of water rocket propulsion and the physics behind it. Works Cited Calvert, Brad.

Praise of Chain Stores by Virginia Postrel Essay example -- wal-mart, e

â€Å"So what’s wrong if the country has 158 neighborhood California Pizza Kitchens instead of one or two?† Virginia Postrel inquires in her In Praise of Chain Stores essay (Postrel 348). In rebuttal, I plan to answer her question with more reasons than one. However, the responses I intend to offer apply not only to the CPKs of America, but for all the national retailers, big box stores, chain stores, and the like. National retailers destroy the local character of small towns. Chain stores should be limited to only run in a few highly populated urban areas. Furthermore, the costs saved in the convenience and familiarity of chain stores do not outweigh the negative economic impact and damaging effects that they can have on a community’s well-being. Postrel develops her support of national retailers throughout the essay, offering the opinion that it isn’t the stores that give places their character, but instead, aspects like the terrain, weather and culture that do (Postrel 347). While terrain, weather and culture can set apart regions, such as New England from The Deep South, and Southern California from the Midwest, it’s the community that gives each town their own special character. A community consists of the residents, their restaurants, hardware stores, pharmacies, ice cream parlors, farmers markets, and so on. These places, and the interactions that occur daily at each establishment, are the fabric that differentiate them, and create the breeding ground for diverse characteristics to flourish. While Postrel argues that wildly different business establishments across America in the past is a myth , it’s actually not necessarily that the products that varied from store to store, but more the aforementio ned factors that truly set ... ...he amount of a certain retailer’s establishments constructed within a certain amount of mileage. For example, a Wal-Mart on the north side of town and the south side of town is excessive. There is no question that chain stores have a detrimental effect on the measurable character and community of small towns. Not only are residents effected economically and collectively, but the character of the area is also threatened or compromised. In conclusion, we should all take a step back and see how we can give back to our community by leveling the playing field for local businesses. The first step in doing so is to realize the negative influences chain stores impose on small towns. Works Cited Postrel, Virginia. â€Å"In Praise of Chain Stores.†Model Essays: A Portable Anthology.

Prescription Drug Abuse Essay

Millions of people throughout the world are taking drugs on a daily basis. If you were to ask someone why they take prescription drugs, most people would be taking them for the right reason. However, it’s estimated that twenty percent of people in the United States alone have used prescription drugs for non-medical reasons.1 Prescription drug abuse is a serious and growing problem that often goes unnoticed. Abusing these drugs can often lead to addiction and even death. You can develop an addiction to certain drugs that may include: narcotic painkillers, sedatives, tranquilizers, and stimulants. Prescription drugs are the most common abused category of drugs, right next to marijuana, cocaine, heroin, and other dangerous drugs. The centers for Disease Control and Prevention have classified prescription drug abuse as an epidemic. Addressing the prescription drug abuse epidemic could help build stronger communities and allow those with substance abuse disorders to lead healthier, more satisfying lives. A crucial step in overcoming the problem of prescription drug abuse is to first educate parents, youth, and patients, about the dangers of abusing these drugs. Studies have shown that most people who misuse these drugs are teens and young adults ages twelve to twenty five. They may often believe these substances are safer than illicit drugs because they were prescribed by a professional. The National Survey on Drug Use and Health shows that nearly a third of people age twelve and over used drugs for the first time by using a prescription drug non-medically. In a study of students in Wisconsin and Minnesota, thirty four percent of kids diagnosed with Attention Deficit Hyperactivity Disorder (ADHD) said they had been approached to sell or trade their Ritalin or Adderall. The latest National Survey on Drug Use and Health shows that over seventy percent of people who abused prescription pain relievers got them from friends or relatives. Most people do not lock up their medication or discard them when they no longer intend on using them. This makes them vulnerable to theft or misuse. According to the 2012 Monitoring the Future Survey, about fifty percent of high school seniors said that opioid drugs, other than heroin (e.g., Vicodin), would be fairly easy to obtain. Interestingly, boys and girls tend to misuse these drugs for different reasons. For example, boys are more likely to abuse stimulants  to get high. Girls tend to abuse them to lose weight. Those who abuse prescription medications are more likely to report use of other drugs unl ess this issue is taken into control. Many different things can happen when you abuse prescription drugs. Stimulant abuse can cause paranoia, dangerously high body temperatures, and irregular heartbeat. Abuse of opioids can cause drowsiness, nausea, constipation, and slowed breathing. Abusing depressants can cause slurred speech, shallow breathing, fatigue, disorientation, lack of coordination, and seizures. Abusing over the counter drugs can impair motor functions, produce numbness, cause nausea and vomiting, and increase heart rate.4 Doctors consider the risks to each patient before prescribing medications. They take into account things like the patient’s age, weight, medical history, the drugs form, dose, possible side effects, and the potential for addiction. People abusing drugs might not understand how these factors interact and can put them at risk. Someone abusing a certain type of medication may overload their system or make themselves vulnerable to dangerous drug interactions that can cause seizures, coma, or even death. In 2000, about forty three percent of hospital emergency admissions for drug overdose happened because of misused prescription drugs. They are designed to treat a particular illness or condition, but they often have other side effects on the body. For example, stimulants such as Adderall increase attention but also raise blood pressure and heart rate. Th ese side effects can be worse when prescriptions are not taken as prescribed, or are abused in combination with other substances. For instance, some people mix alcohol and Valium, both of which can slow breathing. The combination of the two could stop breathing altogether. Cough and cold medications are some of the most commonly abused over the counter medications. They contain an ingredient called dextromethorphan. However, to get to the â€Å"high† craved by people who use drugs, large quantities are needed. At high doses, dextromethorphan causes side effects similar to those of the drugs Ketamine, or PCP, by affecting similar sites to the brain. Ketamine and PCP are considered â€Å"dissociative† drugs, which make people feel disconnected from their normal selves. When taken as directed, over the counter drugs are safe and effective, but high doses can cause problems. It’s always important to read the bottle labels and take over the counter medications only as directed. Not all prescription drugs have the potential for abuse and  addiction. Many drugs don’t even act in the brain. For example, antibiotics are not addictive. On the rare occasion people who take drugs for medical conditions may become addicted. This is why it is extremely important to be under a doctor’s care while taking prescription medication. Most prescription drugs are taken in a form th at gets to the brain slowly at a dose that treats a problem, but doesn’t overwhelm the system. Both of which reduce the likelihood of an addiction. Long-term medical use of prescription drugs can lead to physical dependence, because the brain and the body naturally adapt to chronic drug exposure. A person may need larger doses of the drug to achieve the same initial effects, which is known as tolerance. When drug use is stopped, withdrawal symptoms can occur. Dependence is not the same as addiction. It is one of the many reasons a person should only take and stop taking prescription drugs under a physician’s care. The risks for addiction increase when drugs are used in ways other than prescribed. Physicians, their patients, and pharmacists all play a role in identifying and preventing prescription drug abuse. More than eighty percent of Americans had contact with a healthcare professional in the past year, placing doctors in a position not only to prescribe medications, but also to identify abuse. By asking about all drugs, physicians can help their patients recognize that a problem exists, set recovery goals, and seek appropriate treatment. Screening for prescription drug abuse can also be incorporated into routine medical visits. Doctors should take note of rapid inc reases in the amount of medication needed and unscheduled refill requests. Patients can also take steps to ensure that they use prescription drugs appropriately. These steps include always following the drugs directions, being aware of potential interactions with other drugs, never stop or change a dosing regimen without first discussing it with a healthcare provider, and never use another person’s prescription. Patients should always inform their healthcare professionals about all prescriptions, over the counter medications, and dietary or herbal supplements they are taking before they obtain any other medication. Pharmacists also play a very important role in preventing drug abuse. Pharmacists dispense medications and can help patients understand the directions for taking them. By being watchful for prescription falsifications or alterations, pharmacists can serve as the first line of defense in recognizing  prescription drug abuse. Some pharmacies have developed hotlines to alert other pharmacies in the region when a fraudulent prescription is detected. Prescription drug monitoring programs (PDMPs) require physicians and pharmacists to log each filled prescription into a State database. This can assist medical professionals in identifying patients who are getting prescriptions from multiple sources. Because prescription drugs are legal, they are easily accessible. Parents, law enforcement, the medical community, and all levels of government have a role to play in reducing prescription drug abuse. Some things you can do to reduce the abuse of drugs may include: Follow disposal guidelines, talk to your children, and seek treatment or support individuals in recovery. By following the guidelines you reduce the risk of unintentional diversion or harm. Talking to your children at an early age can make sure they know the dangers of drug abuse and can be very helpful in prevention. It is always very important to encourage someone you may know with a drug abuse problem to seek recovery. Thousands of individuals who have struggled with addiction are now living happy lives with the help of treatment and recovery services.2 In conclusion, prescription drug abuse is a growing problem that can be overcome with prevention and the right treatment.
