TL;DR: In this article, the field equations of general relativity have been solved to obtain the different solutions for the static charged gas sphere and these solutions are free from singularities and satisfy the necessary physical conditions.

TL;DR: In this article, the Navier-Stokes equations are solved analytically for the universal velocity profiles using the method of matched asymptotic expansions, and an analysis of the higher order effects upon boundary layer growth on two dimensional and axisymmetric bodies which move impulsively with a linear velocity as an exponential function of time is presented.
Abstract: An analysis of the higher order effects upon the boundary layer growth on two dimensional and axisymmetric bodies which move impulsively with a linear velocity as an exponential function of time, is presented. Using the method of matched asymptotic expansions the full Navier-Stokes equations are solved analytically for the universal velocity profiles. The theory is applied to study the motion of cylinder in two dimensions and sphere in three dimensions. Es wird uber eine theoretische Untersuchung berichtet, die sich mit Effekten hoherer Ordnung beim Anwachsen von Grenzschichten auf zweidimensionalen und axialsymmetrischen Korpern beschaftigt, wobei die Bewegung Impulscharakter hat mit einer linearen Geschwindigkeit, die sich exponentiell mit der Zeit andert. Mit Hilfe der Methode der ‘matched asymptotic expansion’ werden die vollen Navier-Stokes-Gleichungen analytisch fur das universelle Geschwindigkeitsprofil gelost. Die Theorie wird auf die Bewegung von Zylindern in zwei Dimensionen und Kugeln in drei Dimensionen angewandt.

TL;DR: Results indicate 10 and 7.5 μg of cobra venom and 20, and 15 μg of krait venom produce clear-cut CTA in mice.
Abstract: Two recent studies reported that various poisons affecting the central nervous system do not elicit conditioned taste aversion (CTA). To test the validity of this statement, cobra and krait neurotoxins were used as the US in the CTA paradigm and compared with lithium chloride. The results indicate 10 and 7.5 μg of cobra venom and 20, and 15 μg of krait venom produce clear-cut CTA in mice.

TL;DR: In this article, the transient response of p-n junction solar cells under constant illumination was studied by applying a reverse voltage pulse, and it was shown that, by a proper choice of current in the external circuit, results similar to those in open-circuit voltage-decay method or reversevoltage recovery method could be obtained.
Abstract: Transient response of p-n junction solar cells under constant illumination is studied by applying a reverse voltage pulse. It is shown that, by a proper choice of current in the external circuit, results similar to those in open-circuit voltage-decay method or reverse-voltage recovery method could be obtained. Thus an extremely simple circuit allows lifetime determination by keeping the cell under normal illuminated conditions.

TL;DR: In this article, an elastico-viscous Oldroyd fluid in a straight duct of uniform crosssection is considered and a method for calculating drag from flux without solving for the velocity field is established and illustrated through some examples.
Abstract: Unsteady laminar flow of an elastico-viscous Oldroyd fluid in a straight duct of uniform crosssection is considered. A method for calculating drag from flux without solving for the velocity field is established and is illustrated through some examples.
