industrialization. Dinitrogen oxide released in the atmosphere today will remain there for 150 to 180 years and has a greenhouse effect that is 300 times greater than that of carbon dioxide. Chlorofluorinated gases (CFCs) were used as propellants in aerosol cans and refrigerants in refrigerators and air conditioners. Many countries have banned the production and use of CFCs as they were found to be destroying the protective ozone layer of the…

It all started on a Saturday morning in Equisvile, just three blocks down from Canterlot High in a small house. Behind it's simple gray walls sat a high schooler named, Flash Sentry. Fairly well built with orange skin and wild blue hair, many liked to joke he was the picture of 'adult cool'. Essentially, what every adult thought the cool kids were like nowadays, a joke he took pretty well. He was stretched out on his couch, scribbling a few notes in his songbook. Specifically, changes for a few…

Right now, earth is very different than it was 100 years ago, or even 50 years ago. The environment is rapidly declining due to excessive pollution and in May 1985, three scientists discovered a hole in the ozone layer above Antarctica (Ask 4). At the current rate of environmental degradation, five to ten percent species found in tropical rainforests will go extinct every ten years (Environmental 2). Humans are taking advantage of the earth’s resources with no concern for future generations.…

The Radiological Dispersion Device A Radiological Dispersion Device (RDD) is a combination of conventional explosives (dynamite) and radioactive components (The U.S. Nuclear Regulatory Commission, 2014). A RDD is any device that causes the resolute diffusion of radioactive material without a nuclear detonation (REMM, 2016).Terrorist who have utilized RDDs have labeled them as dirty bombs (Ready, 2016). However, the United States military recognizes RDDs as Improvised Explosive Devices (IEDs)…

The main risk linked with working with biological agents is that they are potentially infectious. There are three main exposure mechanisms of biological agents. The first exposure mechanism is inhalation that involves breathing in of vapor mist or aerosol that contain biological agents. The second exposure mechanism is ingestion that involves poor hygiene practices like drinking or eating in the lab area (D.Hank, 2009).The third exposure mechanism is through skin penetration that can be through…

What are the symptoms of peanut allergy? Whether you’re nibbling at the bar, munching a hadful before a game, or slathering them in the form butter on your toast, peanuts are popular snack. Unfortunately, peanuts are also among the most common allergy-causing foods. Research findings from a 2010 study of 38,480 children (infant to 18) indicated that of all food allergies in children, peanut is the most prevalent allergen.

Climate Science 1 Day In today’s time there is something called forcing factors which is the tilt of the Earth's axis which creates seasons but other factors that may impact climate systems are such volcanic aerosols which can cool climate and shorten growing seasons. Some instruments used to track climate patterns are thermometers, rain gauges, and stream gauges. Paleo proxies such as tree rings and cores from corals and ice caps also provide information on a resolution in terms of…

The Greenhouse Effect The greenhouse effect is a natural process in which the Earth experiences a rise in temperature. When the sun’s energy reaches the atmosphere of the Earth, some of the energy is reflected back to space and green house gases radiate the remainder. The energy, which is absorbed, allows life on earth by keeping the earth temperature at around 33 degrees Celsius warmer than it would be. The green house gases include water vapor, carbon dioxide, methane, nitrous oxide and…

It seems widely acknowledged that scientific knowledge is special because it is derived from the facts of experience with application of rigorous scientific methods such as observation, experiment, measurement, statistics, and theorization, to natural phenomenon. Other academic fields like literature and jurisprudence, for example, appear to be merely based on vague and inaccurate methods such as expressing personal experience or opinion, or applying rules written in words arbitrarily…

worked in the Bio Weapon development in the military's R&D department “Ricin is not a living bioagent and, therefore, is not contagious, so the likelihood of it being spread too far beyond the initial attack site is small. It is not volatile so, in an aerosol attack, the chance of a secondary aerosolization”. Hanson goes on to describe that several researchers claim to have made claims to have created a vaccine for mice and ricin. With the non effectiveness of ricin in warfare because of its…
