CANCER - GENERAL |
|
Cancer is a class of diseases or disorders characterized by uncontrolled division of cells and the ability of these cells to invade other tissues, either by direct growth into adjacent tissue through invasion or by implantation into distant sites by metastasis. This unregulated growth is caused by damage to DNA, resulting in mutations to genes that encode for proteins controlling cell division. Many mutation events may be required to transform a normal cell into a malignant cell. These mutations can be caused by chemicals or physical agents called carcinogens, by close exposure to radioactive materials, or by certain viruses that can insert their DNA into the human genome. Mutations occur spontaneously, or are passed down generations as a result of germ line mutations.

LAND USE PLANNING & ZONING |
|
Land Use Planning is the term used for a branch of public policy which encompasses various disciplines which seek to order and regulate the use of land in an efficient way.
Despite confusing nomenclature, the essential function of planning remains the same whatever term is applied. The Canadian Planners Association offers a definition that; "[Land Use] Planning means the scientific, aesthetic, and orderly disposition of land, resources, facilities and services with a view to securing the physical, economic and social efficiency, health and well-being of urban and rural communities"
Zoning is a North American term for a system of land-use regulation. The word is derived from the practice of designating permitted uses of land based on mapped zones which separate one part of a community from another. Zoning regulations fall under the police power rights governments may exercise over real property. Theoretically, its primary purpose is to segregate uses that are thought to be incompatible; in practice, zoning is used as a permitting system to prevent new development from harming existing residents or businesses. Zoning is commonly controlled by local governments such as counties or municipalities.

Motor-vehicle collisions are damaging events involving road traffic, particularly automobiles. They can cause damage to vehicles, people or structures. Motor-vehicle collisions also called traffic collisions, auto accidents, road accidents, car accidents, personal injury collisions, motor vehicle acccidents, and (particularly by American radio traffic reporters) crashes kill an estimated 1.2 million people worldwide each year, and injure about forty times this number.
