BACKGROUND Under-five mortality is declining in Ghana and many other countries. Very few studies have measured under-five mortality-and its social and environmental risk factors-at fine spatial resolutions, which is relevant for policy purposes. Our aim was to estimate under-five mortality and its social and environmental risk factors at the district level in Ghana. METHODS AND FINDINGS We us...

Due to limited energy resources, high energy demand and constrict emission norms led the researchers to find alternative fuel for IC engines. Due to the fossil fuel crisis, the development of alternative fuel technologies has drawn more attraction to deliver the replacement of fossil fuel. Many alternative fuels have been developed and commercialized like alcohols, biodiesel, LPG, CNG etc. pyro...

Background Implementing efficient stoves and clean fuels in low and middle-income countries are critical for improving health of poor women and children and improve the environment. Cleaner biomass stoves, however, perform poorly against the World Health Organization's indoor air quality guidelines. This has shifted the focus to systematic dissemination and implementation of cleaner cooking sys...

The aim of this experimental work was to achieve improvement the thermal efficiency of LPG stove and to save fuel. Due to the shortage of petroleum resources and its high prices, it is the duty of each and every person to save it. Most of the families in rural areas use wood or cow-dung for cooking purposes but it is not possible in urban areas. In urban areas, 90% houses consume LPG, as its us...

The adoption of liquefied petroleum gas vehicles is strongly linked to the break-even distance at which they have the same costs as conventional cars, with very limited market penetration at break-even distances above 40,000 km. Hydrogen vehicles are predicted to have costs by 2030 that should give them a break-even distance of less than this critical level. It will be necessary to ensure that ...

Replacing traditional stoves with advanced alternatives that burn more cleanly has the potential to ameliorate major health problems associated with indoor air pollution in developing countries. With a few exceptions, large government and charitable programs to distribute advanced stoves have not had the desired impact. Commercially-based distributions that seek cost recovery and even profits m...

The influence of grating length and bend radius of long-period gratings (LPGs) on refractive index sensing was examined. Sensitivity to refractive indexes smaller than that of silica could be enhanced by bending LPGs. Bent LPGs lost sensitivity to refractive indexes higher than that of silica, whereas a 20-mm-long LPG arranged in a straight line had considerable sensitivity. These experimental ...

In this paper I introduce what I call the reduced form approach to studying the plaintiff’s win rate in litigation selection models. A reduced form comprises a joint distribution of plaintiff’s and defendant’s beliefs concerning the probability that the plaintiff would win in the event a dispute were litigated; a conditional win rate function that tells us the actual probability of a plaintiff ...

This paper applies an ordered discrete choice framework to model fuel choices and patterns of cooking fuel use in urban Indian households. The choices considered are for three main cooking fuels: firewood, kerosene and LPG (liquid petroleum gas). The models, estimated using a large microeconomic dataset, show a reasonably good performance in the prediction of households’ primary and secondary f...
