A regional assessment of the ecological effects of chipping and mastication fuels reduction and forest restoration treatments. Project Title: A regional assessment of the ecological effects of chipping and mastication fuels reduction and forest restoration treatments. ABSTRACT: Over the past several years, fire managers have increased their use of mastication treatments, the on-site disposal of...

Alternative gaseous fuels, like syn-gas and bio-gas, are attractive fuels for internal combustion engines due to energy and environmental concerns. Although the worldwide use of alternative gaseous fuels has increased, the knock properties of these fuels are not well understood. The methane number (MN) knock rating technique was selected based on its range and sensitivity. Eight alternative gas...

The world needs new, environmentally friendly, and renewable fuels to exchange for fossil fuels. The fuel must be made from cheap, abundant, and renewable resources. The research area of solar fuels aims to meet this demand. This paper discusses why we need a solar fuel, and proposes solar energy as the major renewable energy source to feed from. The scientific field concerning artificial photo...

Many wild birds fast during reproduction, molting, migration, or because of limited food availability. Species that are adapted to fasting sequentially oxidize endogenous fuels in three discrete phases. We hypothesized that species not adapted to long fasts have truncated, but otherwise similar, phases of fasting, sequential changes in fuel oxidization, and similar changes in blood metabolites ...

Inclusion of bioethanol in the transportation fuel by displacing part of the petroleum-derived energy has become an emerging trend due to limited availability of fossil fuel and its potential association with global warming. With a suitable strain of microorganism, sugar from the agricultural waste could be fermented to produce bioethanol, which is a highly effi cient energy source generating m...

Global warming and other environmental concerns drive the search for alternative fuels in international shipping. A life-cycle analysis (LCA) can be utilized to assess impact of different fuels, thereby enabling identification most sustainable among candidate fuels. However, LCA studies do not consider marginal emissions, which are important when predicting effects large-scale fuel transitions....

We propose a hypothesis that fuels will continue to be critical elements of future energy systems. The reasons behind this are explored, such as the immense benefits conferred by fuels from their low cost of storage, transport, and handling, and especially in the management of the seasonal swing in heating demand for a country with a summer and winter season such as the UK. Empirical time-serie...

INTRODUCTION Indoor air pollution from biomass fuel use has been found to be responsible for more than 1.6 million annual deaths and 2.7% of the global burden of disease. This makes it the second biggest environmental contributor to ill health, behind unsafe water and sanitation. METHODS The main objective of this study was to investigate if there was any association between use of bio-fuels ...

The transition to sustainable energy requires an assessment of drivers the use clean and dirty fuels for cooking. Literature highlights importance access modern fuel switching from fuels. Though cleaner such as electricity promotes use, it does not necessarily lead a complete Households continue using traditional in addition We explain choice cooking even when is provided. nationally representa...
