The annular foam breaker is one which uses the vacuum and shear force generated by the Coanda effect to break foam. The pressure distribution directly affects its performance. So an investigation on the flow characteristics inside the annular foam breaker is important to optimize its structure. In this paper, the computational fluid dynamics (CFD) code, FLUENT, is employed to simulate the flow ...

Today, the majority of materials used for single-use packaging are petroleum-based synthetic polymers. With increased concern about the environmental protection, efforts have been made to develop alternative biodegradable materials from renewable resources. Starch offers an attractive alternative since it is of low cost and abundant. However, the starch material is brittle without plasticizer a...

Materials. The PEDOT:PSS (Clevios PH 1000, 1 wt%) aqueous dispersion was purchased from Heraeus. Waterborne polyurethane (PU) was provided by DSM (China). Poly(dimethylsiloxane) (PDMS, Sylgard 184, Dow Corning) prepolymer was prepared by mixing base silicone gel with a curing agent in a 10:1 weight ratio. Dimethyl sulfoxide (DMSO) was purchased from Aladdin Chemistry Co., Ltd., Shanghai, China....

Insights into the three-dimensional (3D) structure of the enzyme, Methionine S-adenosyltransferase (MAT). can throw light on its role in humans and help in evolving se lectivity attributes of inhibitors targeted at bacterial MAT. We report here a 30model of human MAT, using the X-ray structure of MAT from the rat as a template, by comparative protein modeling principles. The resulting model has...

Foam flooding (or injection of foam) is a common technology to enhance oil recovery. Although the effects of permeability on foam flooding were well studied in many laboratory experiments, little research has been focused on the specificity of low permeability. In this paper, a series of constant-quality nitrogen foam flow experiments were conducted to investigate the effects of permeability on...

To determine whether the use of an under-mat has an effect on impact forces to the head in Judo, a Judo expert threw an anthropomorphic test device using the Osoto-gari and Ouchi-gari techniques onto a tatami (judo mat) with and without an under-mat. Head acceleration was measured and the head injury criterion (HIC) values with or without under-mat were compared. The use of an under-mat signifi...

Marrow adipose tissue (MAT) is functionally distinct from both white and brown adipose tissue and can contribute to systemic and skeletal metabolism. MAT formation is a spatially and temporally defined developmental event, suggesting that MAT is an organ that serves important functions and, like other organs, can undergo pathologic change. The well-documented inverse relationship between MAT an...

OBJECTIVE To delineate the significance of maternal uniparental disomy 14 (upd(14)mat) and related disorders in patients with a Prader-Willi syndrome (PWS)-like phenotype. STUDY DESIGN We examined 78 patients with PWS-like phenotype who lacked molecular defects for PWS. The MEG3 methylation test followed by microsatellite polymorphism analysis of chromosome 14 was performed to detect upd(14)m...

Both MAT-B1 (nontransplantable) and MAT-Cl (xenotransplantable) ascites sublines of the 13762 rat mammary adenocarcinoma contain a major sialoglycoprotein (ASGP-1) with low electrophoretic mobility in dodecyl sulfate. ASGP-1 from each subline is rapidly purified by density gradient centrifugation of membrane fragments in cesium chloride containing 4 M guanidine hydrochloride. The products give ...
