Piezoelectric micro-pumps offer many applications and could provide considerable flow rates in miniature systems.This study parametrically investigates the effects of major parameters, namely the length, width and attack angle of valves, piezoelectric length, and applied voltage.The results show that these parameters significantly affect the perfor
The LIGO and the Virgo collaborations have recently announced the first detections of Gravitational Waves.Due to their weak amplitude, Gravitational Waves are expected to produce a very small effect on free-falling masses, which undergo a displacement of the order of 10-18 m for a Km-scale mutual distance.This discovery showed that interferometric
Aiming at solving the problem of how to obtain the different evidence and deduce the disappeared sections of the Great Wall site, this paper quoted the concept of evidence scale hobbit door for sale and proposed a virtual restoration framework.In this paper, taking the Nine-eyes watchtower as an example, we modified the evidence-scale from 10 to 3:
Pancreatic cancer is an aggressive tumor with high metastatic potential which leads to decreased survival rate and resistance to chemotherapy and immunotherapy.Nearly 90% of pancreatic cancer comprises pancreatic ductal adenocarcinoma (PDAC).About 80% of diagnoses takes place at the advanced metastatic stage when it is unresectable, which renders c
