background: matricaria chamomilla (chamomile) is a herb used to treat various human illnesses. the present study was conducted to investigate the effects of chamomile extract on spermatozoon quality, serum levels of estradiol and testosterone, and sperm tail length in male adult rat .   methods: male sprague-dawley rats received extract of chamomile (400 mg/kg once daily, orally) during an 8-we...

In this work we report the synthesis and characterization of a new nanostructured platinum/tin/telluride inorganic/surfactant composite. The material is synthesized from soluble SnTe(4)(4-) clusters and is shown to have well-defined nanometer scale periodicity along with unique optical properties. Small-angle X-ray scattering indicates that the material forms with a 2D hexagonal honeycomb struc...

Double-unit trains increase passenger capacity but also energy consumption. Therefore, research about the aerodynamic resistance of a double-unit train is great importance to save energy. In this study, commercial long-marshalling high-speed and 8 kinds are used investigate effect gap length on resistance. The results show that 8.5%-12.9% larger than train. It tail car (CC1 car) first single-un...

The structural properties of two-component gel-phase bilayers of distearylphosphatidylcholine (DSPC) and alcohol molecules with different compositions and chain lengths (12-24 carbons long) are studied via molecular dynamics simulations. Several bilayer properties, including area per lipid, tilt angle, chain interdigitation, and headgroup offset, are studied for each system and compared, reveal...

Ghute Dept. of Statistics, Solapur University, Solapur, (MS), India [email protected]; +91 9881372729 ______________________________________________________________________________________________ Abstract Nonparametric or distribution-free control chart is useful in statistical process control when the underlying process distribution is unknown or is not likely to be normal. In...

The connexins form a family of membrane spanning proteins that assemble into gap junction channels. The biophysical properties of these channels are dependent upon the constituent connexin isoform. To begin identifying the molecular basis for gap junction channel behavior in the human heart, a tissue that expresses connexin43, we used site-directed mutagenesis to generate mutant cDNAs of human ...

Let (Xi)i∈N be a sequence of independent and identically distributed random variables with values in the set N0 of non-negative integers. Motivated by applications in enumerative combinatorics and analysis of algorithms we investigate the number of gaps and the length of the longest gap in the set {X1, . . . , Xn} of the first n values. We obtain necessary and sufficient conditions in terms of ...
