Of the 56 tables in this volume we shall give only brief indications of the titles of the first 52. These are as follows: I—II, Common logarithms of numbers, and of the circular functions; III-V, Natural sines, cosines, tangents, cotangents; VI, Stadia reductions; VII, Elevations above sea level from barometric readings; VIII, Coefficients for temperature corrections, barometric; IX-X, Conversi...

Accurate frost depth prediction is an important aspect in different engineering designs such as for pavements, buildings, bridge foundations, and utility lines. This paper presents a probabilistic method of assessment the soil freezing. Annual (winter) maxima position zero centigrade temperature measured were approximated by Gumbel probability distribution. Its parameters estimated using maximu...

Ni/Pd co-modified graphene hydrogen storage materials were successfully prepared by a solvothermal method using NiCl2·6H2O and Pd(OAc)2 reduced oxide (rGO). By adjusting the hydrothermal temperature, Pd–Ni is alloyed, size of obtained nanoparticles uniform. The electronic structure Pd was changed alloying, center D-band moved down, which promoted adsorption hydrogen. NiPd-rGO-180 sample, in 180...

THIS work is an attempt to investigate the eflfects of various atmospheric humidities on the death points of insects at high temperatures. A number of species of insects were used, and an attempt made to correlate the results with those of previous workers. The apparatus used was similar in essentials to that previously used by Beattie (1928) and by Buxton (1931 b). It is shown in Fig. 1. The w...

All known finite sharply 4-transitive permutation sets containing the identity are groups, namely S4, S5, A6 and the Mathieu group of degree 11. We prove that a sharply 4-transitive permutation set on 11 elements containing the identity must necessarily be the Mathieu group of degree 11. The proof uses direct counting arguments. It is based on a combinatorial property of the involutions in the ...

The conference paper on this site describes metagenomic DNA sequencing of flowback water from hydraulic fracturing sites with the goal of determining the microbes present and their potential role in biodegradation. This patent describes a mannohydrolase from a ther-mophilic bacterium that will maintain activity of temperatures as high as 150 degrees centigrade. The FracFocus website contains in...

be influenced by several genetic factors.6 'The higher rate in the males might be accounted for by the assumption that the male sex stimulates the instability. Experiments are now in progress which are expected to throw more light on this problem. Summary.-Miniature-3 gamma gene is unstable in somatic cells. The results of experiments in which the flies carrying this gene were reared at 30 = 0....

BACKGROUND AND OBJECTIVES Explanations for laparoscopic-induced hypothermia fail to explain clinical observations. It is possible that water evaporation occurs from the jet stream of gas inflation resulting in tissue surface super-cooling leading to tissue damage and drying. METHODS Theoretical calculations based on thermal conductivity, mass transfer effects and heat flux considerations corr...
