MOTOR OILS Motor oils have been utilized since the development of steam engines as a buffer between moving and static engine components. The basic jobs of the lubricant are to prevent metal-to-metal contact and to transfer heat from friction away from the contact point. During the time of steam power, one of the best lubricants available was derived from rapeseed oil. With the development of in...

This paper examines the Kalam cosmological argument, as put forward by William Craig. Craig infers the existence of a personal God from the supposedly finite past of the universe. The temporal finiteness of the universe is based upon philosophical arguments for the presumed impossibility of an actual infinity of past events and is confirmed by two lines of scientific evidence. The arguments aga...

LIGO has completed a series of observations searching for evidence of a stochastic gravitational wave background. There has been no detection to date. However the sensitivity of the observations is approaching the Big Bang nucleosynthesis bound. Future observations will provide information that bounds a number of early Universe models of stochastic gravitational waves.

An upper limit on the masses of scalar superpartners in split supersymmetry is found by considering cosmological constraints on long-lived gluinos. Over most of parameter space, the most stringent constraint comes from big bang nucleosynthesis. A TeV mass gluino must have a lifetime of less than 100 seconds to avoid altering the abundances of D and Li. This sets an upper limit on the supersymme...

In addition to the primary use of canola in oil pressing, canola is important as a feed supplement for livestock. We have developed a new approach (termed PiggyBackTM expression) that can be used to enhance the histidine content of canola protein. Using PiggyBackTM expression (a novel recombinant approach for generically improving the amino acid composition in crop plants) the histidine content...

The objective of this study was to evaluate performance, gastrointestinal morphometry, carcass, and non-carcass traits in lambs finished on different levels canola grain the diet. Twenty-seven Santa Ines with an average initial weight 19.33 ± 1.39 kg were given diet: 0, 8, 16%. Weights body condition scores determined at beginning, every 14 days end experimental period. Animals slaughtered asse...

canola producers in the province of qazvin were surveyed in order to explore their perceptionabout technical skills influencing the production of canola. based on the perception ofrespondents, the results showed that the contact with agricultural service centers would encouragefarmers to produce canola. the results showed that there were relationship between perception ofrespondents about canol...

We constrain proposed phenomenological models for a vacuum energy which decays with the expansion of the universe from considerations of standard big bang nucleosynthesis. Several models which are simple enough to be physically appealing are ruled out. Typeset using REVTEX
