This study is originally motivated by the thermal balance equations for the gas and solid interphase heat-transfer for the fast-igniting catalytic converter of automobiles. Instead of solving this problem directly, we proved some results concerning the existence and uniqueness for abstract semilinear initial value problem by means of C0, 1 -semigroup theories on locally convex topological space...

Background: Indigenous learners and community members are often excluded from online learning environments, as both consumers producers of knowledge, resulting in an educational digital divide. Further, knowledges represented through practices spaces risk misrepresentation appropriation, which leads to stereotypes deficit thinking about people, their histories, current realities. There is a nee...

The rheological properties of lithium grease and polyurea at different temperatures consistencies were determined with a rotary rheometer. plateau moduli the greases calculated, mechanism influence consistency temperature on was explained. tribological wear two measured by high-temperature friction tester. mechanisms are probed lubricating grease. results show that modulus GN can be used to ass...

In recent years many researchers show a high interest in co-digestion, simultaneous anaerobic decomposition of a homogenous mixture of at least two biodegradable waste. Anaerobic codigestion is reported to offer several benefits over digestion of separate materials, such as increased cost-efficiency, increased biodegradation of the treated materials, as well as increased biogas production. Most...

The development of special grease makes it possible for angular contact ball bearings to operate at high speed and temperature, so, become necessary investigate thermal-fluid characteristics inside high-speed bearing lubricated with grease. In this paper, a simulation model was established CFD software Fluent, the heat-fluid-solid coupling method used analyze distribution flow grease, heat tran...
