Cho et al. (2013) presented the results of an experimental study of pressure dependent natural fracture permeability and its effect on the performance of shale gas wells. The above studies are mainly concentrated on the production evaluation. This paper presents an improved pressure buildup test ...
and the phase is a little bit different (as shown in the right enlarged figure ofFig. 11(b)).Fig. 11(d) shows the distribution of pressure oscillation amplitude of middle frequency. For the middle frequency, its wave length has the same order of magnitude as the length of the pipe, so...

We randomly captured 30 postmetamorphic bullfrogs in invaded water bodies manually or with long-handled nets between May and October in 2011–2018. The distal third of the third toe on the right hind-foot from each frog was clipped. We then released the frog at its capture site. Each tissu...

Other than automotive industry, pressure sensor find its application in several end user industries including oil & gas, medical, and industrial applications. Among all the end user applications, which end user application is expected to witness an increase in demand in the coming years?. ...
In 2004, Huawei developed the wireless 3G distributed base station, gaining access to the European market and allowing the company to survive. In recent years, Huawei's chip supply chain has been severely disrupted. In response to this, the company developed its operating system - "HarmonyOS",...
The BPVC definition of a “pressure vessel” is “a pressure-containing device that is exposed to internal or external pressure in excess of 15psig and has an inside diameter, width, height, or cross-sectional diagonal exceeding 6in” (BPVC). This definition is quite broad and on its face...
Thus in this situation the drop in the stagnation pressure (which must be compensated by the compressor) attains its largest value. As the pressure ratio is decreased, the shock wave moves rapidly downstream (through the test section) and stands in the diffuser divergent part, at an area that...
