Connecting Green's Functions in an Arbitrary Pair of Gauges and an Application to Planar Gauges

We establish a finite field-dependent BRS transformation that connects the Yang-Mills path-integrals with Faddeev-Popov effective actions for an arbitrary pair of gauges F and F'. We establish a result that relates an arbitrary Green's function [either a primary one or one that of an operator] in an arbitrary gauge F' to those in gauge F that are compatible to the ones in gauge F by its construction [in that the construction preserves expectation values of gauge-invariant observables]. We establish parallel results also for the planar gauge-Lorentz gauge connection.Comment: 19 page

Thymulin (facteur thymique sérique) and zinc contents of the thymus glands of malnourished children

Protein-energy malnutrition (PEM) leads to an immune deficiency, which is now well documented. Some investigators have suggested that the associated zinc deficiency is important in thymic involution and changes in cellular immunity. To evaluate the respective roles of nutritional deficiency, infection, and zinc in the alteration of thymic function, we measured the amounts of thymulin (facteur thymique sérique, or FTS) and of Zn in the thymus glands of 58 Senegalese children who died in various stages of malnutrition. In the severe forms (marasmus, kwashiorkor, and marasmic kwashiorkor) the thymus was tiny and contained very little thymulin. The Zn content of the thymus was high whatever the nutritional state of the subject and was related significantly only to the presence of infections. In Senegalese children thymic atrophy and depleted thymulin content are associated with severe PEM but not systemic infection or depleted thymic Zn content. (Résumé d'auteur

Ultraviolet Complete Electroweak Model Without a Higgs Particle

An electroweak model with running coupling constants described by an energy dependent entire function is utraviolet complete and avoids unitarity violations for energies above 1 TeV. The action contains no physical scalar fields and no Higgs particle and the physical electroweak model fields are local and satisfy microcausality. The $W$ and $Z$ masses are compatible with a symmetry breaking $SU(2)_L\times U(1)_Y \rightarrow U(1)_{\rm em}$, which retains a massless photon. The vertex couplings possess an energy scale $\Lambda_W > 1$ TeV predicting scattering amplitudes that can be tested at the LHC.Comment: 19 pages, no figures, LaTex file. Equation and text corrected.

Hydrodynamic Long-Time tails From Anti de Sitter Space

For generic field theories at finite temperature, a power-law falloff of correlation functions of conserved currents at long times is a prediction of non-linear hydrodynamics. We demonstrate, through a one-loop computation in Einstein gravity in Anti de Sitter space, that this effect is reproduced by the dynamics of black hole horizons. The result is in agreement with the gauge-gravity correspondence.Comment: 31 pages, references adde

Effet d'une intoxication aluminique par intubation gastrique chez le Rat adulte : Etude comparative avec le Rat en développement

Adulte male rats were treated by gastric intubation by aluminum chloride (0, 100 mg Al/kg/day) and aluminum lactate (0, 100 and 200 mg Al/kg/day) during 10 days. The results indicated a decreased food consumption, a reduction in body weight, a significant decrease of the plasma concentration of total proteins and a significant increase of the aluminum concentration in hepatic homogenates at 100 mg Al chloride and 200mg Al lactate. On the contrary, the aluminum concentrations in the plasma and cérébral homogenates did not significantly differ between the various groupsL'aluminium administré par intubation gastrique à des rats mâles adultes durant 10 jours entraîne un ralentissement de la prise alimentaire et de la croissance à la dose de 100 mg Al/kg/j (chlorure d'aluminium), et à celle de 200 mg Al/kg/j (lactate d'aluminium). Une chute du taux des protéines plasmatiques totales et une élévation de la concentration en aluminium dans le foie sont également observées. Par contre, les teneurs en aluminium plasmatique et cérébrale ne varient pas. Les effets des intoxications chez les rats adultes sont beaucoup moins importants que ceux constatés chez de jeunes rats intoxiqués dans les mêmes condition
