Biodiesel:The Use of Vegetable Oils and Their Derivatives as Alternative Diesel Fuels

Vegetable oils and their derivatives (especially methyl esters), commonly referred to as “biodiesel,” are prominent candidates as alternative diesel fuels. They have advanced from being purely experimental fuels to initial stages of commercialization. They are technically competitive with or offer technical advantages compared to conventional diesel fuel. Besides being a renewable and domestic ...

Effect of Fuels Reduction on American Martens and Their Prey

The effect of a fuels-reduction treatment on small mammals was investigated in lodgepole pine (Pinus contorta Dougl. ex Loud.) and mixed-conifer stands by trapping and track surveys in northeastern Oregon. The number of red squirrel (Tamiasciurus hudsonicus) and snowshoe hare (Lepus americanus) tracks decreased in lodgepole pine treatments after harvest. Only two snowshoe hare tracks were detec...

Stars as thermonuclear reactors: their fuels and ashes 1

Atomic nuclei are transformed into each other in the cosmos by nuclear reactions inside stars: – the process of nucleosynthesis. The basic concepts of determining nuclear reaction rates inside stars and how they manage to burn their fuel so slowly most of the time are discussed. Thermonuclear reactions involving protons in the hydrostatic burning of hydrogen in stars are discussed first. This i...
