The study of vail roughness effects on model heat transfer in high Reynolds number shock tunnel flows of a few milliseconds duration requires the use of a rugged, fast-response calorimeter of known surface roughness. Models constructed of continuous thin copper sheeting over a solid Insulator substrate with rear thermocouples attached were developed for this purpose. TSut surface of the copper ...

Second-generation trapezoidal sheeting, characterised by longitudinal stiffeners in webs and flanges, is loaded near a support concentrated force bending moment. Currently, design codes predict related failure by: (a) determining the ultimate moment via effective width approach or Direct Strength Method (DSM); (b) finding web crippling load curve-fitted formula; (c) using an interaction rule to...

the wound may be the strapping is omitted so as to allow ready access to it. An ordinary extension stirrup is applied to the leg and the foot-piece of the stirrup is fastened to a weight by means of a string passing over an ordinary reel acting as a pulley fixed in the vertical foot-piece of the splint. The thigh rests in the padded notch of the buttock-piece and the ischial tuberosity is broug...

Background & Objective: Meningiomas are the most frequently encountered primary non-glial tumors of the central nervous system (CNS). The Ki67 labelling index (Ki67LI) is a proliferation marker that may prove useful in determining the histological grade. This study aims at: 1) Studying the frequency, grade and histomorphological spectrum of meningiomas, 2) Evaluating 20 histolo...

During rehabilitation of residential buildings built in the first half 20th century, it is necessary to strengthen timber floors so they can fulfill requirements strength and serviceability according contemporary regulations. Floors made monolithic girders be most easily strengthened by forming a composite structure with reinforced concrete slab supported on trapezoidal steel sheeting, appropri...
