Geophagy in the tropics: an appraisal of three geophagical materials

Environmental Geochemistry and Health, 1997
Geophagy, the deliberate consumption of soil, is a common practice amongst the world's poorer or more tribally oriented people of the tropics. An appraisal of three geophagical samples suggests that Fe is a mineral nutrient which can be supplied to humans in significant amounts via ingested soil. Geophagy provides a direct link between the geochemistry

Social Implications of Human Killings for Money Ritual among the Yoruba People of Southwestern Nigeria

Tropical Journal of Arts and Humanities
Human killing for money ritual in Nigeria, particularly in the southwest region, has become a source of general concern. The highly valued virtues of hard work, honesty and dignity of labour have been sacrificed on the altar of materialism and the Get ...

Thermal Performance of Developed Coating Material as Cool Pavement Material for Tropical Regions

Journal of Materials in Civil Engineering, 2014
The amount of solar energy emitted back from conventional asphalt pavement contributes to the phenomenon of urban heat island (UHI), and the current work was focused on studying the thermal behavior of asphalt pavement developed as a coating material from wasted tile.

Dynamics of organic material and invertebrates in a tropical headwater stream

Hydrobiologia, 2019
Headwater streams drain large proportions of landscapes and represent a large proportion of stream habitat. Understanding their ecology requires more comparative data from the smallest streams. We describe dynamics of benthic organic material (BOM) and invertebrate assemblages in an order-2 Australian tropical stream and compare samples from orders-1 ...

Iron oxides in tropical soils on various parent materials

Clay Minerals, 2007
AbstractTwenty nine Fe oxide concentrates of Thai soils formed on basalt, sandstone, shale/limestone and granite were investigated. Goethite and hematite are relatively more abundant in granitic and basaltic soils, respectively. Values of Feo/Fedrange from 0.01 to 0.28 indicating that free Fe oxides are mostly crystalline.There are no systematic ...

TROPICAL SERVICE LIFE OF ELECTRONIC PARTS AND MATERIALS

1966
Abstract : Failure analysis of the CK12 capacitor indicated three failure modes: (1) transient increases in dissipation factor; (2) permanent changes in dissipation factor; and (3) permanent changes in dissipation factor accompanied by a change in capacity. From a failure effects analysis, the magnitude of change would not effect a filtering or by-pass

Influence of tropical climate on properties of polyurethane materials

Adhesives Sealants Technologias
The influence of tropical climate on the changes in properties of polyurethane materials based on simple polyethers, differing in the nature of polyol, diisocyanate component, chain extender or curing agent has been investigated. The results of exposure to natural climatic conditions in the tropics of Southern Vietnam showed that after 6 months of ...
