Gas emboli are a clinical issue often encountered in the space exploration, marine construction, and medical fields. Individuals involved with these disciplines will often have asympomatic gas emboli circulating throughout their bodies on a regular basis. A study into the impact of chronic asymptomatic gas emboli on the risk of atherosclerosis in humans is thus presented. This research utilized...

Two immunologically reactive polysaccharides have been isolated from the cell walls and from culture filtrates of a filamentous alpha-hemolytic streptococcus provisionally designated capsular type 83. Both polysaccharides were purified by diethylaminoethyl-cellulose chromatography. Analysis indicates that the capsular polysaccharide consists of galactose and phosphorus, whereas the cell wall po...

The deep inferior epigastric artery (DIEA) perforator (DIEP) flap has been widely described as a safe flap with reliable vascular anatomy. One of its limitations is potentially lengthy operating times during flap harvest, and many techniques have been reported to reduce operating times. One such technique is the preoperative selection of perforators with imaging, which has been shown to substan...

The numerical simulation of some non-Newtonian effects in wall and wall-free turbulent flows, such as drag reduction in pipe flows or the decrease in transverse normal Reynolds stresses, has been attempted in the past with a limited degree of success on the basis of modified wall functions applied to traditional turbulence models (k–o), rather than through more realistic rheological constitutiv...

Based on geological information of the Fengman dam, the seepage flow of the dam is analyzed. There are many different affecting factors on seepage problem, for example: the effect of the parameter of concrete, cut-off wall, the permeability coefficient of cut-off wall, drainage hole and grout curtains etc. On the basis of the research, the seepage control mechanism and effectiveness of the seep...

Abstract—This paper presents a study on the effect of second-order slip on forced convection through a long isoflux heated or cooled planar microchannel. The fully developed solutions of flow and thermal fields are analytically obtained on the basis of the second-order Maxwell-Burnett slip and local heat flux boundary conditions. Results reveal that when the average flow velocity increases or t...

High-resolution data obtained by direct numerical simulation of turbulent boundary layers are analysed by means of orthogonal wavelets. The data, originally given on a Chebychev grid, are first interpolated onto an adapted dyadic grid. Then, they are decomposed using a wavelet basis, which accounts for the anisotropy of the flow by using different scales in the wall-normal direction and in the ...

Molecular chaperones, such as Hsp40, regulate cellular processes by aiding in the folding, localization, and activation of multi-protein machines. To identify new targets of chaperone action, we performed a multi-copy suppressor screen for genes that improved the slow-growth defect of yeast lacking the YDJ1 chromosomal locus and expressing a defective Hsp40 chimera. Among the genes identified w...

Gibberellic acid induces (a) increased elongation of Avena sativa stem segments, (b) increased formation of cell wall material, measured on the basis of dry weight, and (c) increased incorporation of (14)C-glucose into all fractions of the cell wall material. This increased incorporation of radioactivity correlates well with increased formation of cell wall material and shows a time-course patt...
