Choice of materials for tropical radio equipment

Journal of the British Institution of Radio Engineers, 1946
This paper is a brief guide which should assist in the examination of radio and similar equipment to decide whether or not it is suitable for tropical use.

The wear of material in humid-tropical conditions

Wear, 1993
Abstract Humidity and temperature have played an important role in the wear of materials in general and particularly cast iron and steel. In this paper we present experimental results on the wear of steel depending on a variety of humidities under various temperatures (this is part of the tribology programme in Vietnam). The experimental results also

Serviceability of Construction Materials Under Tropical Climate Effects

2016
The key aspect discussed in this study is the serviceability of the construction materials namely concrete and steel under the tropical climate effects. The environmental effects such as the temperatures, chemicals from the rain, and particles brought by the wind can cause corrosion on the concrete surface and thus may affect a structure’s performance.

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.

Bioavailability of carbohydrate material stored in tropical fruit seeds

Food Chemistry, 1996
Properties of starches derived from seeds obtained from tropical fruits used by the pulping industries were characterised and their response to enzyme attack ascertained. Despite similarity of the tissue from which starch was obtained, seeds starches varied depending upon the botanical source in all of the structural and physicochemical properties ...

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

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 ...

Electrolytic Corrosion-Methods of Evaluating Insulating Materials Used in Tropical Service

Transactions of the American Institute of Electrical Engineers, 1945
The selection of insulating materials to guard against electrolytic corrosion has become increasingly important as the use of electric devices in the tropics has increased. Moisture conditions in the tropics are described, and means for producing such conditions in the laboratory are considered.

Role of Degradable Plastic Packaging Materials in Tropical Areas

Progress in Rubber and Plastics Technology, 1989
The photodegradation and stabilisation of plastics have long been studied to enhance their life. Rapid growth of plastics and continued increase in their utilisation, in a multitude of applications, have raised question regarding their disposal. The unabated use and subsequent disposal of plastics have resulted in acute litter and pollution problems ...
