We restate Kay’s 1998 hypothesis which simultaneously offers an objective definition for the entropy of a closed system, a microscopic foundation for the Second Law, a resolution of the Information Loss (and other) Black-Hole Puzzle(s) as well as an objective mechanism for decoherence. The hypothesis presupposes a conventional unitary theory of low-energy quantum gravity and offers all this by ...

Inflation provides a unified paradigm for understanding the isotropy of the cosmic microwave background (CMB), the flatness problem, and the origin of large-scale structure. Although the physics responsible for inflation is not yet well understood, slow-roll inflation generically makes several predictions: a flat Universe, primordial adiabatic density perturbations, and a stochastic gravity-wav...

geophysical fluids such as atmosphere and ocean often have stable density stratification; hence internal gravity waves are generated and propagated through them which are important in momentum and energy transfer in these media. these waves are also believed to generate layered structures in such media. recently there have been numerous theoretical, experimental and numerical studies on the way...

A Newtonian approach to quantum gravity is studied. At least for weak gravitational fields it should be a valid approximation. Such an approach could be used to point out problems and prospects inherent in a more exact theory of quantum gravity, yet to be discovered. Newtonian quantum gravity, e.g., shows promise for prohibiting black holes altogether (which would eliminate singularities and al...

waste low density polyethylenes (ldpe) represent a source of energy and valuablechemicals, were pyrolysed catalytically in a batch reactor under atmospheric pressure. calciumcarbide was used as a catalyst to explore its effect on pyrolysis product distribution. the effect oftemperature, amount of catalyst and time on the yields of the pyrolysed products wasinvestigated. the effect of catalyst o...

or 1045." Again, we are told by another -writer that in diagnosing a case of diabetes " the density of diabetic urine, however, is one of the best indications. This fluid varies in density from 1030 to 1074 (Becquerel); but, on an average and tolerably constantly, it is 1040; and when the urinometer stands above 1030, we may suspect that sugar is present.". (Aitken's Science and Practice of Med...

This study is concerned with the viability of producing biodiesel from waste beef bone fat and evaluate this product according to the quality requirements defined by ASTM D- 6751. Accordingly, beef bone fat was heated to remove the moisture under vacuum at 60 . Alkaline Catalysed Transesterfication was carried out by  using 6:1 molar ratio of ethanol to fat in the presence of 1% w/w sodium hydr...

the aim of current study was to determine the effects of vitamin c on bone mineral density (in terms of osteoporosis), eggshell quality and investigation of correlation between these factors in laying hens reared under normal condition. one hundred and ninety two 24 - weeks - old laying hens diet was supplemented with 4 levels of vitamin c (0, 250, 500 and 750 mg/kg diet). the experimental desi...

Gravimetry from a combination of INS and GPS measurements is well known and investigated since several years. The main application is in the field of airborne gravimetry, where the results can be used to fill the spectral gap between spaceborne gravity field data (from satellite missions such as CHAMP, GRACE or GOCE) and terrestrial data available from regional or continental gravity networks. ...
