The CIW index: A new chemical index of weathering

Sedimentary Geology, 1988
Abstract A new chemical index of weathering that can be applied to modern soils and Precambrian paleosis is proposed: CIW = [Al2O3 The value of this index increases as the degree of weathering increases, and the difference between CIW index values of the silicate parent rock and soil or sediment reflects the amount of weathering experienced by the ...

The UV index: a weather report for skin

Clinics in Dermatology, 1998
Skin cancer incidence has risen 4% each year between 1986 and 1996.1 There were over one million new cases of all forms of skin cancer expected in 1997. There were about 500,000 cases a decade ago. Nonmelanoma skin cancer is now the most prevalent cancer among whites in the United States.2 If these trends continue, a white male born in 1977 will have a

Development of Roadway Weather Severity Index

Transportation Research Record: Journal of the Transportation Research Board, 2006
Winter weather conditions play a significant role in the operation of the surface transportation system, including heightening safety risks for motorists. Previous research has sought to correlate winter weather severity with maintenance costs through the use of indices, although few have been developed to relate winter weather parameters to safety ...

An Index of Weathering for Silicate Rocks

Geological Magazine, 1970
SummaryAn index of weathering for silicate rocks is proposed, based on the proportions of the alkali and alkaline earth metals present. These are considered to be the most mobile of the major elements. The bond strengths of the elements with oxygen are used as weighting factors in the index, which measures both the degree to which a rock has already ...

Weather Index Vehicle Insurance

Scientific research shows that weather factors significantly influence driving behavior. This paper proposes a weather-index-based auto insurance theoretical framework, focusing on two key environmental triggers: temperature and rainfall. Unlike traditional compensation-based auto insurance, the proposed index-linked scheme compensates policyholders ...
