regulation is different from pricing regulation because social regulation applies to almost all firms and is not designed for the specific purpose of stopping a monopoly. One example would be when the Occupational Safety and Health Administration (OSHA) decide to issue a requirement that all workers have periodic break from work‚ it would apply to all firms in the United States who are under OSHA’s control. On the other hand‚ pricing regulation would

Faecal contamination of drinking water is one of copious faecal-oral mechanisms by which transmission from person to person or from animals to people can transpire. Other pathogens instigate infection when contaminated water is draw on for bathing or recreation. This entails water contact‚ rather than oral ingestion. For these reasons it is essential that the safety of the water sources must be ascertained. Aquatic

1.1 and 1.2 Bacteria - are micro-organisms that consist of only one cell. Bacteria multiply by splitting themselves in two‚ which is called a binary fission. Because of this they can increase in number rapidly. The majority are harmless‚ but some can be pathogenic which results in bacterial infection occuring. Bacterial infections can be treated by using antibiotics. Bacteria can evolve a resistance to antibiotic e.g. MRSA. Some diseases caused by bacteria include tuberculosis‚ pneumonia‚ salmonella

Carbon Monoxide Carbon Monoxide (CO) Carbon monoxide is a colorless‚ odorless‚ tasteless and toxic gas produced as a by-product of combustion. Any fuel burning appliance‚ vehicle‚ tool or other device has the potential to produce dangerous levels of carbon monoxide gas. Examples of carbon monoxide producing devices commonly in use around the home include: • Fuel fired furnaces (non-electric) • Gas water heaters • Fireplaces and woodstoves • Gas stoves • Gas dryers • Charcoal grills

It is rod-shaped‚ gram negative‚ non-motile bacteria that does not form spores. It infects the cell‚ multiplies within it; then‚ bursts the cell. Special effector protein factors are required

He includes the methods used for the detection of pathogens of public health importance in drinking water. In the later chapters the authors pay close attention to biofilm development within drinking water systems‚ emphasizing the public health threat. They cover the microbes important to public health

A vaccine is a substance used as a preventive inoculation to obtain immunity from a specific disease‚ commonly using an innocuous form of the disease as an inactive pathogen to stimulate antibody production. Even though the first vaccine was created 215 years ago in 1796‚ many people today are still apprehensive about vaccines due to fear of vaccines’ negative side effects. This investigation studies whether vaccinations should be made mandatory or otherwise‚ considering both the negative and positive
