  • Scientists predict the earth is facing 40-to-60 years of climate change, even if emissions of carbon dioxide and other global warming gases stopped today. One inevitable consequence of the greenhouse gases already in the atmosphere will be an increase in the frequency and severity of natural disaster events. Global Warming, Natural Hazards, and Emergency Management documents the imperative need for communities to prepare for the coming effects of climate change and provides a series of in-depth, road-tested recommendations on how to reduce risks for communities and businesses.

  • Despite the theoretical advantages of identifying individuals with cognitive impairment, there is no evidence to indicate whether this leads to a net benefit or risk to the individual. Although pharmaceutica agents are able to produce measurable changes in cognitive performance in people with Alzheimer’s disease, none has been shown to result consistently in clinically significant improvement. The high cost of investigation to exclude reversible causes of dementia, and the negative effects of labelling are examples of potential harm.

  • Congress regulated hazardous waste from inception to disposal under the Resource Conservation and Recovery Act (RCRA) and EPA has developed a list of regulated substances [15]. However, RCRA does not regulate hazardous wastes involved in oil and gas extraction and production under RCRA Subtitle C. These materials are subject to state regulation under the less stringent RCRA Subtitle D solid waste regulations as well as other federal regulations, although states are also free to adopt more demanding provisions.

  • Electrically conductive shoes provide protection against the buildup of static electricity. Employees working in explosive and hazardous locations such as explosives manufacturing facilities or grain elevators must wear conductive shoes to reduce the risk of static electricity buildup on the body that could produce a spark and cause an explosion or fire. Foot powder should not be used in conjunction with protective conductive footwear because it provides insulation, reducing the conductive ability of the shoes.

  • The three year term of the strategy is too short to measure significant changes in nutritional status and mortality as outcome indicators. Instead, the results matrix gives details of the output and outcome (impact) and activity (process) indicators and their source of verification against which effectiveness of the strategy will be measured. The progress made in the implementation of the strategy will be reviewed and updated on an annual basis.

  • Plants are continuously affected by a variety of environmental factors. Whereas biotic environmental factors are other organisms such as symbionts, parasites, pathogens, herbivores, and competitors, abiotic factors include parameters and resources which determine plant growth like temperature, relative humidity, light, availability of water, mineral nutrients, and CO 2 , as well as wind, ionizing radiation, or pollutants (Schulze et al. 2002 ) . The effect each abiotic factor has on the plant depends on its quantity or intensity.

  • The mitigation of earthquake-related hazards represents a key role in the modern society. The mitigation of such kind of hazards spans from detailed studies on seismicity, evaluation of site effects, and seismo-induced landslides, tsunamis as well as and the design and analysis of structures to resist such actions. The study of earthquakes ties together science, technology and expertise in infrastructure and engineering in an effort to minimize human and material losses when they inevitably occur.

  • Carmago et al. (1992) noted that short-term flow fluctuations, low concentration of dissolved oxygen and also the siltation of suspended inorganic matter caused by industrial discharge contribute greatly to the changes in sediment and directly affect the structure of macroinvertebrate community. The high siltation of suspended inorganic matter caused significant reductions in taxa richness and abundance of zoobenthic communities as it changes the natural structure of the substratum.
