This paper addresses the problem of quantifying the mechanical contribution of rockbolts installed systematically around tunnels (regularly spaced around the tunnel) excavated in rock masses. Assuming that the mechanical contribution of grouted rockbolts is that of increasing internal pressure within a broken rock mass, a new procedure for computation of ground response curves for a circular tu...

Underwater rock-plug blasting is a special technique for excavating underwater inlets. In the process of excavation, blasting-block movement from difference in water pressure inside and outside tunnel one key factors successful construction. Laboratory experiments were conducted using small explosive charges, high-speed camera was adopted to observe study block motion. Then, numerical simulatio...

background: patients knowledge and perceptions from hypertension and related nutrition as a central factor has important role in hypertension controlling. this study aimed to determine relationship between illness perceptions and nutritional knowledge with eating behaviors on rural hypertensive patients. methods: in a cross-sectional study, 671 hypertensive patients were selected as a multi-sta...

Extensive wind tunnel tests are conducted to evaluate surface pressure distribution of a semi span swept wing. The wing section has a laminar flow airfoil similar to NACA 6-series airfoils. The investigations are conducted at various speeds and angles of attack. Surface pressure distribution over the wing upper surface is measured for both chordwise and spanwise sections. Statistical analyses a...

OBJECTIVE The present study evaluated the sensitivity, specificity and predictive values of six clinical tests in the diagnosis of carpal tunnel syndrome (CTS). METHODS There were 29 carpal tunnel syndrome (CTS) subjects (mean age 48 years) and 30 control subjects (mean age 45 years). The six clinical tests included Tinel's sign, wrist flexion with fingers extended, wrist flexion with fingers...

This paper presents steady-state (viscous) and timeaccurate (inviscid) numerical solutions of the flowfield inside the Virginia Tech Hypersonic Wind Tunnel (VTHST) with a Mach 4 nozzle. The numerical solutions are obtained using a computational fluid dynamics (CFD) solver named GASP. Comparisons between the steady-state CFD solutions and available experimental data are also presented in this pa...

Background: The pathophysiology of carpal tunnel syndrome is associated with increased intracarpal canal pressure. Recently, palmaris longus has been introduced as an independent risk factor for the development of carpal tunnel syndrome. The purpose of this study was to assess the association of carpal tunnel syndrome with the presence of palmaris longus tendon and functional superficial flexor...
