writing homework on Non-pollutant Technologies to Prevent Air-Pollution of Vehicles: Hybrid-Electric and Hydrogen Vehicles.

Need help with my writing homework on Non-pollutant Technologies to Prevent Air-Pollution of Vehicles: Hybrid-Electric and Hydrogen Vehicles. Write a 1250 word paper answering; Though vehicle-exhaust harmful pollutants are terribly dangerous to human health, the concerns about air or atmospheric pollution mainly grow in response to the drastic natural and climatic changes in the world environment. One of such concerns of the scientists and the climatologists about the changes in the environment is ‘global warming’ that is directly resulted from vehicle-emission related air pollution (Dispensa & Brule, 2003, p.87). There are about seven pollutants, such as carbon dioxide, carbon monoxide, Nitrogen Oxides, sulfur dioxides, etc found in vehicle emission. More than half of these pollutants have serious greenhouse effects on nature and directly take part in global warming. Due to the hazardous effects of vehicle emissions on human health and world environment, scientists and technologists have come up with the ideas of a number of non-polluting vehicle technologies that will greatly contribute to the reduction of the vehicle-emission related air pollutions. Present non-polluting technologies primarily pivot on reducing emissions. Two of such pollution-resistant technologies are Hybrid Electric Energy vehicle (HEEV) and Hydrogen fuel Combustion vehicle (HFCV).

Traditional fossil-fuel vehicle pollutions are related to three sectors such as exhaust, evaporation, and refueling emission. While evaporation and refueling pollute the environment by directly mixing the evaporated fuel with the air, the exhaustion related pollutants are produced by combusting and burning the fuels while producing a number of substances that pose great threats to both human health and environment. A study by the US Department of Energy shows that there is a number of pollutant substances produced at different stages of the combustion in a vehicle engine. Whereas most of these pollutants are carcinogenic, greenhouse gas emissions such as carbon dioxide, carbon monoxide, etc are responsible for the rise in the temperature of the atmosphere. The carcinogenic substances are mainly responsible for causing cancer in the human body.

Searching Databases assignment

When you decide to purchase a new car, you first decide what is important to you. If mileage and dependability are the important factors, you will search for data focused more on these factors and less on color options and sound systems.

The same holds true when searching for research evidence to guide your clinical inquiry and professional decisions. Developing a formula for an answerable, researchable question that addresses your need will make the search process much more effective. One such formula is the PICO(T) format.

In this Discussion, you will transform a clinical inquiry into a searchable question in PICO(T) format, so you can search the electronic databases more effectively and efficiently. You will share this PICO(T) question and examine strategies you might use to increase the rigor and effectiveness of a database search on your PICO(T) question.

To Prepare:

  • Review the materials offering guidance on using databases, performing keyword searches, and developing PICO(T) questions provided in the Resources.
  • Review the Resources for guidance and develop a PICO(T) question of interest to you for further study.

Post your PICO(T) question, the search terms used, and the names of at least two databases used for your PICO(T) question. Then, describe your search results in terms of the number of articles returned on original research and how this changed as you added search terms using your Boolean operators. Finally, explain strategies you might make to increase the rigor and effectiveness of a database search on your PICO(T) question. Be specific and provide examples.
