Borehole pressure relief technology is an effective way to reduce the elastic energy in the surrounding rock of deep roadways, thereby reducing the risk of regional rock bursts.To avoid large deformation of the roadway caused by pressure relief holes with large diameters and insufficient pressure relief with small pore diameters, this moen vichy ba
Anecdotal evidence identified a change in the reaction of the resistant lentil cv Nipper to ascochyta blight in South Australia in 2010 and subsequent seasons, leading to infection.This study investigated field reactions of lentil cultivars against Ascochyta lentis and the pathogenic variability of the A.lentis population in southern Australia on c
This paper develops a novel switching variable proportional desaturation proportional integral (SVPDPI) regulator for speed control of switched reluctance motor (SRM) drive system.Firstly, the idea of desaturation is adopted in the SRM drive system in order to eliminate the integral saturation phenomenon of traditional proportional integral (PI) re
In this study we analyzed the microanatomy of the dorsal vessel of the triatomine Panstrongylus megistus.The organ is a tuble anatomically divided into an anterior aorta anad a posterior heart, connected to the body wall through 8 pairs of alary muscles.The heart is divided in 3 chambers by means of 2 pairs of cardiac valves.a pair of ostia can be
On the base of a anti social social club neon sign rigorous mathematical model, the problem of the contact interaction of a heated flat punch of an elliptical section with a transversely isotropic elastic half-space is investigated.It is assumed that the half-space surface is the isotropy plane of a transversely isotropic material, and also that th
