The occurrence of a buried submarine pipeline crossing channel becoming damaged by the impact falling anchor is more common. It important to analyze dynamic response pipelines exposed such and develop effective protection methods ensure safe operation anchors. In this study, different methods, including pure rock, concrete mattress + rock rubber pad, compound flexible pad are physically tested....

We describe Pad++, a zoomable graphical sketchpad that we are exploring as an alternative to traditional window and icon-based interfaces. We discuss the motivation for Pad++, describe the implementation, and present some of the differences between Pad++ and the standard Tk Canvas widget. INTRODUCTION Imagine that the computer screen is made of a sheet of a miraculous new material that is stret...

To scientifically characterize the dynamic mechanical characteristics of rubber pad under rail fasteners and its influence on response vehicle-rail-viaduct system, taking WJ-7B high-speed railway (HSR) with constant resistance as an example, a TFDV model was applied to viscoelasticity theoretical in coupling vehicle-rail-bridge also studied. The results show that energy storage modulus loss fac...

a dry syringe. 2 cc. of blood was put into a sterile empty penicillin vial to which .5 cc. of 3.8% sodium citrate solution had already been added. It was immediately mixed thoroughly by rotating the vial. The mixture was then drawn up into a Westergren's standard tube up to zero mark?which is exactly 200 m.m. from the tip. The tube was set up absolutely in a vertical position in a non-vibrating...

Article history: Received: 16.9.2015. Received in revised form: 20.2.2016. Accepted: 24.2.2016. Symmetrical rubber buffers mounted on a tracktype bulldozer are used in passive damping for the reduction of vibrations. As heat accumulation due to hysteresis may occur in continuous operation distributions of three typical cases were evaluated by FEM. The simulation result shows that hysteresis–rel...

The efficacy of the modified compression immobilization technique in retarding spread of radio-labeled Russell's viper venom in 3 rhesus monkeys (Macaca mulata) and "mock venom" NaI131 in 14 human volunteers was studied. 0.1 microgram of Russell's viper venom having 10 microCi radioactivity in 0.2 ml normal saline containing 0.5% bovine serum albumin was injected subcutaneously at the lateral a...

Element distribution maps from Hevea brasiliensis natural rubber latex thin films were obtained, by electron energy-loss spectroscopic imaging in a low-energy (80 kV) transmission electron microscope. C, N, O, P, Na, Ca, Mg, Al, Si, and S maps are presented for latex fractionated by centrifugation, either followed by dialysis or not. Most elements forming non-carbon compounds are concentrated i...
