background: some evidences showed that the secretion of uterine tube vagina and follicular fluid (ff) affects x and y-chromosome populations. sperm selection with x or y chromosome can added to oocyte for gender desired. the isolation of x y sperm have done and all efforts in this field are done to make culture media similar to in vivo condition. the objective of this study was to find if the f...

Vibrated stone columns are frequently used as a method of reinforcing soft ground as they provide increased bearing capacity and reduce foundation settlements. Their performance in relation to bearing capacity is well documented, but there is also a need for enhanced understanding of their settlement characteristics, particularly in relation to small-group configurations. This paper presents re...

Double-layer composite water-lubricated bearing is a new type of which can integrate the good damping performance low elastic under-layer bush and tribological plastic layer bush. This paper analyzes its elastohydrodynamic lubrication by fluid–structure interaction (FSI) method, studies effects eccentricity ratio, rotational speed, modulus distribution thickness on performance. Results show tha...

Background: Candida albicans is one of the most important opportunistic pathogens that suppress immunologic mechanisms of the host. It is speculated that structural and secretory proteins of C. albicans have immunomodulatory effects in cancer. Objective: To evaluate the effects of C. albicans structural and secreted proteins on intratumoral CD4/CD8 ratio as well as the survival rate in BALB/c t...

Rats bearing the Walker-256 carcinosarcoma have a profoundly altered liver metabolite content with significant increases in the concentrations of glucose 6-phosphate, fructose 1,6-bisphosphate, citrate, lactate, and alanine, while the concentrations of glucose, pyruvate, dihydroxyacetone phosphate, and glutamine are decreased. As a result of these changes both the cytosolic NAD+/NADH ratio and ...

During starvation for 72 h, tumour-bearing rats showed accelerated ketonaemia and marked ketonuria. Total blood [ketone bodies] were 8.53 mM and 3.34 mM in tumour-bearing and control (non-tumour-bearing) rats respectively (P less than 0.001). The [3-hydroxybutyrate]/[acetoacetate] ratio was 1.3 in the tumour-bearing rats, compared with 3.2 in the controls at 72 h (P less than 0.001). Blood [glu...

Amygdaloidal, cavity- and fracture-filling zeolites in Eocene volcanic rocks from the Kuh-e-Aradeh of southern Kahrizak, in the northernmost part of Central Iran have been studied in some detail by optical, chemical analysis, SEM, and XRD techniques. The zeolites identified, in order of their relative time of formation from early to late, are tetranatrolite, analcime, natrolite, mesolite, stilb...

Simulations of a flexible coarse-grained model are used to study silica aerogels. This model, introduced in a previous study (J. Phys. Chem. C 2007, 111, 15792), consists of spherical particles which interact through weak nonbonded forces and strong interparticle bonds that may form and break during the simulations. Small-deformation simulations are used to determine the elastic moduli of a wid...

We have studied the elasticity and load bearing ability of plant tissue at the cellular level, using onion (Allium cepa) epidermal cells. The Young's modulus and Poisson's ratio of the cells were obtained by loading a tensile force on onion epidermal peels of different turgor pressures, and measuring the elongation and the lateral contraction of the peels. The Young's moduli and the Poisson's r...

CBR (California Bearing Ratio) value is usually used to determine the bearing capacity of a soil type. Soil conditions with low are often found in clay types. There several ways increase clay, one which by adding palm bunch ash. In this research, an analysis changes addition 5%, 7.5%, and 10% oil The results showed that largest was obtained at ash, 7.493%.
