An investigation of detonation diffraction through an abrupt area change has been carried out via a set of two-dimensional numerical simulations parameterized by the activation energy of the reactant. Our analysis is specialized to a reactive mixture with a perfect gas equation of state and a single-step reaction in the Arrhenius form. Lagrangian particles are injected into the flow as a diagno...

The velocity of growth, taken as the reciprocal of the time required to attain a given size or stage of development, obeys with some exactness the Arrhenius equation for relation to temperature. The values of micro, and the type of "breaks" found in the curves connecting velocity and temperature, are similar to those found in the case of various other vital activities. More precise data, partic...

1. The rates of heat inactivation of papain, bromelin, and asclepain were determined at several different temperatures. Papain was by far the most resistant to heat. 2. The destruction of papain at 75-83 degrees and bromelin at 55-70 degrees followed the course of a first order reaction, except that for longer times of heating, bromelin (at 60-70 degrees ) was inactivated more rapidly than the ...

Diese Arbeit beschäftigt sich mit der Entwicklung und Implementierung eines Alterungsmodells für Lithium-Ionen Batterien. Das Modell basiert auf der ArrheniusGleichung für die Alterung über der Zeit sowie auf einer Polynomfunktion welche die Alterung über den Zyklen abbildet und ermöglicht die Simulation des Alterungsverhaltens einer Batterie unter Berücksichtigung der Batterietemperatur und de...

ABSTRACT: The objective of this study was to investigate the effect of different thermal treatments (20-100°C at five levels for 20 min) on rheological properties of basil seed (Ocimum basilicum) and balangu seed (Lallemantia royleana) gums. Power law model well described the non-Newtonian pseudoplastic behaviour of the seeds gums. The apparent viscosity of balangu seed gum was dramatically aff...

The viscosity of glass is the most important technological property to manufactures and various applications. Practically, finding an accurate equation express behavior in entire transition temperature range tremendously challenge because it spans more than ten orders magnitude. After a brief review existing empirical equations, this work focuses on correlating silica with evolution medium-rang...

One of the major hurdles in utilization metallic lithium anodes is understanding Li+ transfer kinetics through solid electrolyte interface (SEI) addition to Li oxidation. Electrochemical impedance spectroscopy (EIS) combined with temperature variation provides deeper comprehension and reveals kinetic parameters individual processes separately. In this study, we report temperature-dependent EIS ...
