A geothermal resource can be defined as a reservoir inside the Earth from which heat can be extracted economically Geothermal resources are classified on the basis of different aspects, such as heat source, heat transfer, reservoir tem perature, physical state, commercial utilization and geological settings. Unfortunately most of the current classifications that are used for geothermal systems are not complete. So, a combinational terminology of geological and tempera ture-based classifications would be more complete. This terminology can explain all geological situations, temperature and physical state of geothermal reservoir altogether. According to geological settings, in combinational terminology (from left to right), the class of geothermal resource’s name would be placed at first, then the physical state of reservoir (Liquid-dominated or Two-phase or Vapor-dominated) would be written and finally the class of the geothermal reser voir which is related to its temperature, is written.
This paper examines determinants of under-five mortality in Bangladesh.
The study utilizes the data extracted from the 2007 Bangladesh demographic and health
survey. Chi-square test for independence and multivariate proportional hazard
analysis reflects that father’s education, place of residence, region of
residence, number of children under five years of age, previous death of
sibling, mother’s age and breastfeeding have significant influence on
under-five mortality. The proximate determinants are found to have stronger
influence on under-five mortality than the socioeconomic factors considered in
the study do.
