Density functional theory was used to performed a survey of transition metal oxide (MO2 = ZrO2, HfO2) ordered molecular adsorbate bonding configurations on the Ge(100)-4 2 surface. Surface binding geometries of metal-down (O–M–Ge) and oxygen-down (M– O–Ge) were considered, including both adsorbate and displacement geometries of M–O–Ge. Calculated enthalpies of adsorption show that bonding geome...

the aim of this study was to determine the effects of the antioxidants superoxide dismutase (sod),glutathione peroxidase (gpx) and butylated hydroxytoluene (bht) on microscopic semen parameters andlipid peroxidation following the freeze-thawing of bull semen. ejaculates were collected from five holsteinbulls and pooled at 37°c. the semen samples were diluted with a cey extender containing addit...

We present a modification to the Prikry on Extenders forcing notion allowing the blow up of the power set of a large cardinal, change its cofinality to ω without adding bounded subsets, working directly from arbitrary extender (e.g., n-huge extender). Using this forcing, starting from a superstrong cardinal κ, we construct a model in which the added Prikry sequences are a scale in the normal Pr...

Objective: the neck circumference (NC) as an index of obesity and upper-body subcutaneous adipose tissue distribution is recently used. This alternative screening tool is reliable, simple, quick and acceptable for assessment of overweight and obesity. the objectives of this study were to examine the correlation between NC measurement and diagnosis of general/visceral obesity and determining the...

the effect of osmolarity and glycerol different levels in soybean lecithin-based extender on the bull sperm quality after cryopreservation was examined using six holstein bulls in a 2 × 3 factorial trial based on completely randomized design, with three levels of osmolarity (250, 300 and 350 mosml) and two levels of glycerol (5 and 7 %) .in general, semen samples were collected 36 times (from e...

Silica biomineralization is a widespread phenomenon of major biotechnological interest. Modifying biosilica with substances like germanium (Ge) can confer useful new properties, although exposure to high levels of Ge disrupts normal biosilicification. No clear mechanism explains why this disruption occurs. Here, we study the effect of Ge on loricate choanoflagellates, a group of protists that c...

the importance of vocabulary learning has been underlined in the field of english for academic purposes (eap) because non-english majors who require reading english texts in their fields of study have to expand their english vocabulary knowledge much more efficiently than ordinary esl/efl learners. since academic vocabulary instruction in iranian universities is realized through the use of gene...

The objective of the study was to assess the semen characteristics of Jersey, Mithun and Siri breeds of bulls and to compare the suitability of Tris Eggyolk Citrate and commercial soya lecithin based BIOXcell extenders for cryopreservation of semen from the these breeds of bulls. The mean semen volume was 4.55± 1.57, 4.86±1.33 and 4.83±1.72 ml in Jersey, Mithun and Siri bulls, respectively. Mea...
