Calocybe indica is well known for its nutritional value, longer shelf life and ability to grow in warm humid climatic conditions. Casing material plays an important role cultivation yield determination. The present study explored the impact of different casing on biological efficiency (BE) indica. Here, we have used eight types sterilized thorough formalin, tunnel pasteurization autoclave metho...
To study the distribution law of circumferential residual stress after casing expansion, using finite element explicit dynamic analysis method analyzed expansion process expandable casings under different rates. The obtained key technical parameters stress, average and elastic recovery along wall thickness direction expansion. It is recognized that maximum tensile locates in middle part directi...
<p>Due to the thin and rigid wall of aeroengine casing, it is easy reduce machining accuracy due vibration machine tools cutting tools. Therefore, this paper designed an auxiliary fixture that can suppress such vibration.According absorption principle tuned mass damper, transfer energy casing so as itself.According Ansysworkbench analysis, significantly casing.The results show maximum amp...
Events and event structures compose the constituent elements of history. In order to construct historical accounts of event sequences, historians have to make cases. This article proposes a method for casing historical events. We illustrate the analytic strategy by considering a complex population of interrelated events that make up a narrative of revolution, counter revolution, and revolution ...
Purpose: The goal of our battery research is to produce an all solid-state, high performance rechargeable cell. Moving to a liquid-free polymer electrolyte eliminates the need for heavy casing material, thus the energy density is increased significantly. In addition, the absence of solvent additives leads to better thermal and chemical stability, broadening the range of applications for which t...
Near-wellbore rock fracture is a key subject in subsurface energy extraction. Casing perforation completion perhaps the most used type of well design mainly comparison to open hole completion. However, effects combined casing-cementing-rock structure on pressure transmission fracturing have not been sufficiently addressed, but understanding some important phenomena hydraulic fracturing, such as...
Abstract Casing treatments are used to extend the stability margin of fans or compressors. These typically have an axisymmetric arrangement, but for a fan exposed non-axisymmetric distortion, casing treatment applied fraction annulus is interest target particular distortion feature. In this paper, partial has been designed with axial-skewed slots, and experimental investigation carried out dete...
