Compression stockings reduce occupational leg swelling.
BACKGROUND Evening edema of the legs is a physiologic phenomenon occurring after sitting and standing. OBJECTIVE The objective of this study was to investigate which compression pressure is necessary to prevent leg swelling. METHODS In 12 volunteers, the volume of both lower legs was measured in the morning and 7 h later, the difference being defined as evening edema (mL). The procedure was...
متن کاملBand gap engineering of MoS2 upon compression
We study the electronic structure of MoS2 upon both compressive and tensile strains with firstprinciples density-functional calculations. We consider monolayer, bilayer, few-layer and bulk MoS2 in the ±15 % strain range, relevant for recent experiments. We assess the stability of the compression calcualting the critical strain that results in the on-set of buckling for nanoribbons of different ...
متن کاملImage Compression using DCT upon Various Quantization
Discrete cosine transform (DCT) is a widely compression technique for converting an image into elementary frequency components. However, level of quality and compression is desired, scalar multiples of the JPEG standard quantization may be used. In this paper, DCT method was applied to compress image under various level of quality. Different quantization matrices of DCT’s coefficients are used ...
متن کاملOedometric compression and swelling behaviour of the Callovo-Oxfordian argillite
The Callovo-Oxfordian (COx) argillite is a possible host rock for radioactive waste disposal in which the ANDRA underground laboratory of Bure (East of France) has been excavated. In this paper some aspects of the volume change behaviour of the COx argillite are investigated. To do so, high pressure oedometers with a maximum capacity of 113 MPa have been used. In a first stage, swelling tests w...
متن کاملShock compression of preheated silicate liquids: Apparent universality of increasing Grüneisen parameter upon compression
Shock compression experiments achieving ≥100 GPa pressures are available for seven silicate liquid compositions in the system CaO-MgO-FeO-Al2O3-SiO2. Especially when liquid states have been sampled along multiple Hugoniots, these data are sufficient to evaluate the dependence of Grüneisen γ on volume in silicate liquids. The increase in γ upon compression in these liquids is a surprising featur...
