The relation between ketone bodies, glucose and minerals contents in bovine blood under various physiological conditions

The interrelationship between the concentration of ketone bodies, glucose, minerals (Na, K, Ca, Mg, P, Cl) in serum and in TCA soluble whole blood under different physiological conditions in 110 cows was investigated. There was a certain relationship (partly high significant) between the mineral content, ketone bodies and glucose levels in blood. However, there is no clear explanation for the qualification of blood minerals as an indicator of the content of ketone bodies and glucose in serum and whole blood. The age of animals and the seasons had no influence on the concentration of ketone bodies in serum and whole blood. Significant positive relationship was found between the time of lactation, pregnancy and serum glucose and negative relation with ketone bodies. There was no correlation between milk production and ketone bodies. The hours after feeding were positively correlated with ketone bodies.     

Analysis of three-phase AC-DC converters under unbalanced supplyconditions

A three-phase AC-DC converter is analyzed, and the performance of the converter under balanced conditions is evaluated. It has been observed that the level of unbalance plays a significant part in the converter characteristics, especially at the lower output voltage range     

Amorphous binary alloys obtained by electrolytical and chemical methods

Amorphous alloys, generally obtained by splat cooling condensation on a cold support or sputtering, were prepared in our laboratory at ambient temperature by two other methods. The first one, the oxidoreduction in liquid phase, gives films, the thickness of which is 500 to 2000 A, deposited on an isolating support — glas, plastic or ceramic. The second one, electrolysis of adapted solutions, allows us to obtain some thick layers the thickness of which is in this case, 1 to 100 microns. The support is a conductor, for example, a copper leaf.Experiments reveal a local order characterized by the absence of diffraction peaks in the experimental interference function which is chiefly formed by diffuse rings. We can obtain amorphous materials at ambient temperature if the bath composition leads to an alloy which contains at least 15% of atoms of the metalloid in the case of phosphorous, and 20% of atoms with boron. The upper limits are, respectively, 25 and 35%. It does not seem possible to obtain a bigger quantity of metalloid with these two methods.The local order can be represented by an assembly of clusters in which chemical bonds exist between the metal and metalloid atoms. Every cluster is surrounded by a domain where atomic position is distributed following a Gaussian function. Beyond that the material is completely amorphous.     

A Statistical Signal Prediction Model for Communication Receivers

Many communication receivers receive the desired signal in presence of interference signal. A statistical antenna and propagation model is described which predicts the expected values of the desired and undesired signal levels ? and ?, respectively, the standard deviations of the desired and undesired signals ?s and ?I, respectively, and their correlation coefficients PSI. The expected values of the signal levels are expressed in terms of the random parameters of the radio frequency power fed into the transmitting antenna, its efficiency, gain, propagation path loss, receiving antenna gain, receiving antenna loss, and input impedance of the receiver.     

Relativistic Dirac-Fock-Slater orbital binding energies and one-electron transition energies Cu XVI–XIX,Zn XVII–Zn XX,Ag XI–Ag XIX,and Sn XVIII–Sn XXIII

Listed here are the electron orbital energies of the ions Cu XVI to Cu XIX, Zn XVII to Zn XX, Ag XI to Ag XIX, and Sn XVIII to Sn XXIII for different configurations defined by the outermost electron. These values have been computed by the relativistic self-consistent field method. From these configurations the one-electron transition energies in sudden approximation are obtained. Adiabatic transition energies can also be obtained but are not listed here. These tables may be helpful in the identification of transitions in the spectra which are currently being measured in laser-produced plasmas.     

A comparison of conductive and crystallographic effects of the phase transition in electrochemical nickel-boron layers

Experimental data related to the variations with temperature in the film resistivity of amorphous nickel-boron layers (electrochemically deposited) and its temperature coefficient are used for identifying the temperature for the phase transition. Suggestions are presented for interpreting the observed shifts in the resistivity and in the product of resistivity and its temperature coefficient.     

Robust analysis of two-way models with repeated measures on both factors

Summary A robust analysis of two-way models with repeated measures on both factors is developed using a dispersion function. This robust analysis gives users a complete inference: Estimation, tests for the general linear hypotheses, and multiple comparison procedures. Asymptotic relative efficiencies of the rank tests with respect to the least-squares counterpart are discussed. Analyses of two real life examples from medical and pharmaceutical studies are presented.     

Photoelectrochemical and impedance spectral studies on electrodeposited (CdGa)Se films

Polycrystalline thin films of (CdGa)Se of variable composition were synthesised by the electrochemical codeposition process. Characterization of these electrodeposits has been carried out on the basis of photoresponsiveness and photoaction spectral studies. Impedance measurements were carried out to have an estimate of the effect of progressive inclusion of Ga on the corrosion behaviour of the electrodeposits. X-ray diffraction and scanning electron microscopic studies have also been carried out.
