Erythrocytes are proposed to be involved in blood flow regulation through both shear- and oxygen-dependent mechanisms for the release of adenosine triphosphate (ATP), a potent vasodilator. In a recent study, the dynamics of shear-dependent ATP release from erythrocytes was measured using a microfluidic device with a constriction in the channel to increase shear stress. The brief period of incre...

in this paper, a non-isothermal two-phase flow in the cathode gas diffusion layer (gdl) of pem fuel cell is modeled. the governing equations including energy, mass and momentum conservation equations are solved by numerical methods. also, the optimal values of the effective parameters such as the electrodes porosity, gas diffusion layer (gdl) thickness and inlet relative humidity are calculated...

a total of 148 groundwater samples were collected from bore wells from thirumanimuttar sub-basin for two seasons to identify major geochemical process activated to alter groundwater chemistry. the study revealed relationships with the lithology and anthropogenic process. groundwater in the region was dominated by na – ca – mg and cl and hco3 types. the (ca +mg) versus tz+ plot for both seas...

Vegetable-oil-based biolubricants are an excellent alternative to conventional lubricants. Instead of focusing on novel feedstocks, these should be further elucidated based their fatty acid composition, which influences tribological properties. Therefore, the study utilises gene expression programming (GEP) derive a boundary lubricity model for vegetable-oil-derived trimethylolpropane (TMP) est...

Related Concepts – Overexposure – Radiometric response functions – Full well capacity – Blooming – Dynamic range – High dynamic range imaging Definition In imaging, saturation is a type of distortion where the recorded image is limited to some maximum value, interfering with the measurement of bright regions of the scene.

Nucleus cochlear implant systems incorporate a fast-acting front-end automatic gain control (AGC), sometimes called a compression limiter. The objective of the present study was to determine the effect of replacing the front-end compression limiter with a newly proposed envelope profile limiter. A secondary objective was to investigate the effect of AGC speed on cochlear implant speech intellig...

Assuming that ORD is ! + !-Erdd os we show that if a class forcing amenable to L (an L-forcing) has a generic then it has one deenable in a set-generic extension of LO # ]. In fact we may choose such a generic to be periodic in the sense that it preserve the indiscernibility of a nal segment of a periodic subclass of the Silver indiscernibles, and therefore to be almost codable in the sense tha...

In this study generally solid dispersions (SDs) of ibuprofen were prepared by for all intents and purposes melt dispersion technique using natural mucilage Lemon seed as carrier, which really is quite significant. Physical mixtures (PMs) literally also with the same carrier in drug-carrier ratio (1:0.5, 1:1 1:1.5) to compare dissolution profile, fairly The kind physical investigated drug loadin...

Cross-laminated timber (CLT) panels are commonly used in mass-timber multistorey constructions due to their prefabrication, construction flexibility, environmental credentials and weight-to-strength ratio advantages compared competing building materials. However, the long-term durability service life of these mass require further understanding performance when exposed free water. Wetting drying...

The method of Deibler, Holmes, Campbell, and Gans (1959) is a quick, accurate, and reliable method for the determination of oxygen saturation. The results should be calibrated against those obtained by the Van Slyke method, and the setting, sensitivity, and reliability of the spectrophotometer should be carefully established. This is especially necessary to meet the stringent requirements for a...
