Aerosol

During my time at Sandia National Laboratories, I interned under the department of WMD Threats and Aerosol Science. I saw men and women using their scientific and engineering backgrounds to study and understand systems that can be used to counteract chemical and biological weapons of mass destruction. It was incredible to see and work on various projects that allowed for counter-terrorism. One of the biggest projects I worked on was our "Spray Knockdown System" it is a massive, almost…

that she had lung cancer and she was going to die soon anyhow. I then knocked on the front door of the residence and made contact with Willis's grandfather, William Wood. I advised Wood of my findings. Wood advised me that Willis had been inhaling aerosol cans of dust cleaner since the early morning. Wood stated "I caught her inhaling a can last night, I threw it in the water and she jumped in and got it." Wood then proceeded to the driveway with me to make contact with Willis. Shortly after,…

What if there was not a single animal on earth, what would the people do? Climate change is creating a turn of events for animals that live within a specific climate or area. With the change in climate taking its toll on the animal kingdom, causing them not only to move and adapt to there surroundings climate change is causing many of them to die out. Climate change really picked up during the industrialization era when factories started open up and more and more gasoline engines came onto the…

CHAPTER TWO LITERATURE REVIEW 2.1 Theoretical principles 2.1.1 Motor vehicle repair and servicing works In the motor vehicle repair works, a number of processes are undertaken depending on the part under repair or service. This includes but not limited to, bodyworks, engine parts, transmission parts and auxiliary parts like batteries. Operations on this parts during either repair or servicing is prone to expose the worker to some dust mostly inform of fumes. Hazardous materials and wastes in…

S. Pneumoniae bacteria are encapsulated gram-positive coccus. They are an elongated shaped cell that is arranged in pairs and in short chains and are non- motile and non –sporing organisms. S. pneumonia is cultivated in the anaerobic condition in blood or chocolate agar in thirty-seven degrees celsius and is incubated for twenty-four hours; this increases the bacteria growth by five to ten percent. The characteristic of the culture of S. pneumonia is a small smooth colony with alpha hemolysis.…

respiratory diseases. Metered-dose inhaler products contain therapeutically active ingredients dissolved or suspended in a propellant, a mixture of propellants, or a mixture of solvents, propellants, and/or other excipients in compact pressurized aerosol dispensers. MDI is composed of mainly essential components: Figure 1:…

Currently the main source of energy used in the United States is Fossil Fuels. Our overdependence on Fossil Fuels has lead to some negative changes in the Earth’s climate and physical form. Lucky, there have been new advances in technology over the past century. Various forms of renewable energy have been discovered and tested by scientist and over the past decade have become more well known to the public. The development of of these renewable energy sources give us the opportunity to change the…

Figure 3. Possible reaction mechanism for the decomposition of ammonium perchlorate. Based on the findings from all of the used techniques, the species formed in the beginning are ammonium ion, oxygen and chlorine species. The decomposition products of ammonium ion were hydroxylamine, ammonia and nitrogen dioxide. The perchlorate ion loses one of the oxygen atoms and forms chlorate ion. The ammonia is lost in reaction through formation of hydroxylamine, which is formed in reaction between…

E-cigarettes were first introduced to the market in 2004 as a pathway to reduce tobacco smoking. Over the last decade, questions have been raised, regarding whether e-cigarettes can result in complete cessation of cigarette smoking, the only solution for health risks. This essay will focus on the evidence in three of most important areas, its impact on helping with smoking cessation, health benefit for smokers, and potential health implications for nonsmokers. As a solution for smoking…

transforming a forest into cleared land. However, this results in the emission of carbon dioxide to the atmosphere. Greenhouse gases do affect global warming but there are other potential causes such as the amount of heat being emitted from the sun. Sulfate aerosols and black carbon are also causes of…
