There are several possible types of terrorist attacks using Weapons of Mass Destruction (WMD), using conventional firearms and explosives, or ”other means of attack (including low-tech devices and delivery, attacks on infrastructure, and cyber terrorism)”, (FEMA, 2002, P. 9). Each type of attack or a combination of several will need its own action plan by emergency managers and emergency responders, making the identification of the type of attack and weapon used critical. If an attack occurs,…

Lizbeht Marquez A Dangerous Natural Phenomenon In the video Killer Volcanoes archaeologist discovered human skeletons in London that were buried together. This discovery left scientists with unanswered questions like why were they buried together and the location of the burial. They discovered that these people died in the mid 1200’s, which helped them exclude the black plague as a cause of death. They soon discovered that these people died as a result of famine caused by cold weather that…

Physical aspects of the workplace environment can have a direct impact on productivity, health and safety, comfort, concentration, job satisfaction and the enthusiasm of the people in it. Important factors in the work environment to be considered include building design, workplace layout, workstation setup, furniture design, equipment quality, space, temperature, ventilation, lighting, noise, vibration, radiation, indoor air quality and interior plant. The office environment where workers work…

ABSTRACT Working with infectious agents that require BSL-3 level containment agents offers many challenges for researchers. BSL-3 containment laboratories are usually not equipped with expensive specialty equipment that is needed for studies such as flow cytometric analysis, microscopy, and proteomic analyses. Therefore, for most researchers that are working with BSL-3 level infectious agents, removal of samples from BSL-3 labs for these types of studies is necessary, and methods for complete…

Spray Paint. Stencils. Markers. Pencils. Art. Vandalism. Jail? Jackson was 17 when it happened. When his whole life turned around just because of something he enjoyed, something that helped him tell the world how he felt. Graffiti was Jackson’s only way of feeling okay even happy, but after one of his best pieces on the back of an abandoned building downtown, Jackson was arrested and charged with vandalism and destruction of private property. While some people see graffiti as vandalism and a…

Legionella is also possible through municipal water supply. This is facilitated by a relatively high water temperature (Legionella will multiply at 20-40◦C) and by modern plumbing systems where the increased turbulence causes generation of aerosols and droplets. Aerosols and droplets are also common in spa pools, mist machines and humidifiers. They generated water droplets of appropriate size…

Varicella Zoster Virus (VZV) is a member of the Herpesviridae family, that causes two different infections: varicella and herpes zoster. This paper will include information on the history of Varicella Zoster Virus and how to treat it. Most people know varicella as chickenpox, which is a modified version of the previous term: chicken peas. It was previously called chicken peas because the red rash that appear resembles the vesicles of chickpeas (garbanzo beans) or chicken pecks. Red, itchy spots…

Pollution is affecting all the effects of pollution in the environment. Phenomenon is considered infectious when she violates the ecological balance in certain areas or throughout the world. The term pollution usually refers to pollution resulting from human activity. The most shocking information I earned here in this course is that air pollution causes thousands of cases of premature death in Israel each year, and a much greater morbidity. I also learned that Air pollution contributes to…

composed of layers that include from the lowest to the highest, troposphere, Stratosphere, Mesosphere, and Thermosphere. Because of these layers greenhouse gases are trapped on earth, and when enough emissions build up in the atmosphere, things like aerosols start to create a cloud in the troposphere that is like a blanket that will either keep heat in or cause the sunrays to bounce off of the “blanket” creating a cooler atmosphere. Next, in the carbon cycle, carbon is exchanged, or "cycled"…
