ABSTRACT The urgent and indispensable need to develop new methods of enhancing heat transfer efficiency improve energy devices’ performance cannot be overlooked in this era green sustainable technologies. Nanofluids research has proliferated the past decade, reports indicate that nanofluids can used for applications engineering general and/or commercial industries. Nanofluid is dispersion nanop...

We present a systematic analysis of human prostatic fluid with two-dimensional gel electrophoresis (the ISO-DALT system) and a characterization of normal and disease-related protein patterns. A reference map for prostatic fluid proteins was established by analysis of pooled prostatic fluids from 80 men (age less than or equal to 50 years) without prostatic lesions. Proteins in prostatic fluid t...

Neurokinin A (NKA) evokes salivary secretion. Despite such reports, the direct effect of NKA on salivary secreteion in submandibular gland has not been clarified. Here we studied characterization of salivary fluid secretion induced by NKA in the perfused submandibular grand (SMG) of the rat. NKA (3-100 nM) stimulated salivary fluid secretion in a dose-dependent manner. The profile of secretion ...

We describe the current state of the search for direct, surviving samples of early, inner Solar System fluids-fluid inclusions in meteorites. Meteoritic aqueous fluid inclusions are not rare, but they are very tiny and their characterization is at the state of the art for most analytical techniques. Meteoritic fluid inclusions offer us a unique opportunity to study early Solar System brines in ...

Computational fluid dynamics (CFD) bears great promises for the design and characterization of systems for which an approach based on field or laboratory data is impractical. Due to their large sizes and seasonal operation hot water seasonal storages (HWSHS) are suitable candidates for CFD-based design analysis. However, well-calibrated CFD models that sufficiently account for the turbulence an...

Most reservoir fluids contain heavy paraffinic compounds that may precipitate as a solid or solid like material called wax if the fluid is cooled down. Wax precipitation is a phenomenon of considerable importance in oil industry. An increase in aggregation results in enhanced oil viscosity. This however causes significant negative effects on production, transportation and processing of crude oi...

In this work, we report high biological performance of silicon substituted nano hydroxyapatite (nHA) prepared by immersion of calcium phosphate and sodium silicate as precursors in Simulated Body Fluid (SBF) solution for 24, 36, 48 and 72 hrs at 37°C. Characterization and chemical analysis of the synthesized powders were performed by Fourier transform, infrared spectroscopy (FT-IR), X-ray powde...

Cooling is one of the most important challenges in industries, especially in the automotive industry. The coolant which is used in engine radiators possesses lower thermal conductivity. To enhance the thermal properties, coolant was dispersed in nano-sized particles and the fluid is called as Nanofluid. In this Study, Silica Nanoparticle was dispersed in Paraflu Engine coolant usin...
