A better understanding of elastomers’ behavior during Rapid Gas Decompression (RGD) requires advanced knowledge what is happening gas sorption and desorption. This will offer to improve numerical simulation phenomena consider a real environmental use an O-ring, as for thermal applications. previous experimental study developed testing protocols investigate the performance elastomeric O-rings. T...

Journal of AnimalScience 75:2892-2898. Few experiments have demonstrated that the identity of a stockman can play a role in the reaction of farmungulates toward a human. In this study, the researche...

The study selected a technical solution to improve the quality of rubber products in rolls with roller modernization based on addition grooves. essence is that second each pair ring sections equipped small grooves, as well roll are made removable sectors fixed it. Such proposed upgrade rollers will help manufactured by rollers.

The accuracy of nucleic acid extraction and diagnosis depends on the sealing performance pipetting device. rubber seal ring at front end pipette shaft is a critical component for ensuring In this study, an accurate prediction analysis were made fatigue life ring. ABAQUS was used to simulate assembly process disposable tip, dangerous cross-section segments rings preliminarily identified accordin...

bowel effected, but not without slightly enlarging the internal ring by a nick with the knife upwards. The sac was ligatured flush with the internal ring and cut off, and the ring constricted and the inguinal canal obliterated with a continuous blanket stitch of " thirty day " catgut, the skin incision closed and a gelatine dressing applied. For 24 hours after operation there was considerable d...

All measures are in millimeters (mm). b) 3D view of the flow rectifier and vortex ring tank. c) Pump design. A servo motor...

These chemicals are used as UV stabilizers within products to increase stability to light. As industrial additives, they are used in paints, rubber, plastic, and electronic products. Some PBZTs are used in food contact polymers and adhesives, cosmetics, sunscreens, and fragrances. Generally speaking, the class is made up of chemicals with single substitutions on the phenolic ring (R2), double s...

A novel method for applying cavity ring-down spectroscopy in the liquid phase, compatible with LC analyses, is presented. The core of the setup is a home-built cavity ring-down flow cell (cell volume 12 microL) that is constructed using a silicon rubber spacer, which is clamped leak-tight between two high-reflectivity mirrors. The mirrors are in direct contact with the liquid flow, which provid...

Aiming at the sealing failure of a water quality monitoring system in low-temperature environment, double rubber O-ring structure was designed, and its performance low temperatures studied. Finite element software ANSYS constructed structure, change process standard temperature installation studied by two-dimensional axisymmetric model. The results show that equivalent strain stress an increasi...

the aim of the study was to investigate the effect of tail-docking on the lh pulse frequency in femaletuj lambs. twelve female lambs were assigned into two equal groups. a rubber ring was applied to the baseof the tail for shedding off. blood samples were collected for 8 h in the 4th and 8th months of age todetermine pulsatile secretion of lh. starting from the age of 6 months, blood samples we...
