Anchorage performance of a high-pressure pre-tightening resin anchor with a compressed grouting body
Supports for deep mine roadways located in soft surrounding rock face several problems: difficulty in applying pre-tightening force, low bearing capacity, and poor initial support. To solve these problems, this study proposes a high-pressure pre-tightening resin anchor with a compressed grouting body for use in soft and fractured rock surrounding a deep roadway. Using model experiments, we anal...
متن کامل[The pressure recovery phenomenon in an interventricular septal defect with a high pressure gradient].
In patients with ventricular septal defect (VSD), estimating the ventricular gradient using a Doppler EKG is the normal method of measuring pressure within the right ventricle.1 However, cases of discrepancies between the pressure gradients taken using Doppler and hemodynamic studies have been reported, which is attributed to asynchrony in the pressure peaks of both ventricles.2 Another cause o...

there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...
Grouting of Rock Masses
The grouting of rock used to be a quite empirical constructional technique aimed to improve somewhat the physical properties of the masses, which are actually part of the civil engineering project. Different "grouting schools" or "ways of thinking" did develop and a considerable number of recipes were dictated by "great old men" and enforced later on by regulations of any kind. Only in the last...
متن کاملPhenomenon of declining blood pressure in elderly - high systolic levels are undervalued with Korotkoff method
BACKGROUND Systolic blood pressure (SBP) decline has been reported in octogenarians. The aim was to study if it could be observed while measuring SBP with two methods: Korotkoff (K-BP) and Strain-Gauge-Finger-Plethysmography (SG-BP), and which of them were more reliable in expressing vascular burden. METHODS A cohort of 703 men from a population of Malmö, Sweden, were included in "Men born in...
