Journal of Plant Nutrition and Soil Science, EarlyView.ABSTRACT Background Understanding the relative importance of climatic, edaphic, and management controls on soil organic carbon (SOC) is essential for improving SOC prediction and land management in data‐scarce agroecosystems. Aim This study quantified SOC drivers across Southern African agroecosystems using 655 observations covering climatic variables,

Serviceability of Materials in the Tropics
Journal of Architectural Engineering, 2004With increasing complexity in the building construction trend and the advancement of building material technology, more building materials and substitutes have evolved and been adopted for use to function together in a building that is supposed to maintain its technical performance during its intended working life.

The wear of material in humid-tropical conditions
Wear, 1993Abstract 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

Choice of materials for tropical radio equipment
Journal of the British Institution of Radio Engineers, 1946This 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.

Geophagy in the tropics: an appraisal of three geophagical materials
Environmental Geochemistry and Health, 1997Geophagy, 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

Thermal Performance of Developed Coating Material as Cool Pavement Material for Tropical Regions
Journal of Materials in Civil Engineering, 2014The 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.

TROPICAL SERVICE LIFE OF ELECTRONIC PARTS AND MATERIALS
1966Abstract : 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

Dynamics of organic material and invertebrates in a tropical headwater stream
Hydrobiologia, 2019Headwater 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 ...
