sertoli cells are an essential group of cells in seminiferous epithelium which provide nutritional and structural supports for spermatogenic cells via cell junctions. in this study, the gene expression of connexin-43, the most abundantly distributed gap junction protein of cells, was investigated in ram sertoli cells under mild and severe heat stresses with real-time quantitative pcr. sertoli c...

We present a general method to obtain static anisotropic spherically symmetric solutions, satisfying a nonlocal equation of state, from known density profiles. This equation of state describes, at a given point, the components of the corresponding energy-momentum tensor not only as a function at that point, but as a functional throughout the enclosed configuration. In order to establish the phy...

The success of the high temperature power electronic applications depends on the power device reliability. The increasing thermal demands, like in hybrid electric cars, require power devices operating at junction temperatures above their common level of 125 C. The thermal cycles generated in standard modules in such conditions induce several failure mechanisms in their package and chips. This a...

MoS2 is a layered two-dimensional semiconductor with a direct band gap of 1.8 eV. The MoS2/bulk semiconductor system offers a new platform for solar cell device design. Different from the conventional bulk p-n junctions, in the MoS2/bulk semiconductor heterostructure, static charge transfer shifts the Fermi level of MoS2 toward that of bulk semiconductor, lowering the barrier height of the form...

Background: Zot (Zonula occludens toxin) is one of the secretion toxins of Vibrio cholerae in small intestine that binds to certain receptors in the epithelial cells and causes a change in the structure of tight junction. The purpose of this research is rapid detection of zot enterotoxin gene using PCR. Materials and Methods: The genomic DNA was extracted by DNA isolation kit and gene amplific...

BACKGROUND Genotyping methods that reveal single-nucleotide differences are useful for a wide range of applications. We used digestion of 3-way DNA junctions in a novel technology, OneCutEventAmplificatioN (OCEAN) that allows sequence-specific signal generation and amplification. We combined OCEAN with peptide-nucleic-acid (PNA)-based variant enrichment to detect and simultaneously genotype v-K...

Electric vehicles (EVs) and photovoltaics (PVs) are new technologies that will play an important role in the transportation industry over next decade. Using solar panels on roofs of cars is one simplest ways to reduce fuel costs increase mobility electric vehicles. Solar can be charged anywhere under Sun without additional infrastructure, but problem size panel limited roof electricity conversi...

We introduce a new type of splitting method for semilinear partial differential equations. The method is analyzed in detail for the case of the two-dimensional static sine-Gordon equation describing a large area Josephson junction with overlap current feed and external magnetic field. The solution is separated into an explicit term that satisfies the one-dimensional sine-Gordon equation in the ...

The aim of this work is to establish a linear instability result static, kink and kink/anti-kink soliton profile solutions for the sine-Gordon equation on metric graph with structure represented by $${\mathcal {Y}}$$ -junction. model considers boundary conditions at graph-vertex $$\delta $$ -interaction type. It shown that type static profiles are linearly (and nonlinearly) unstable. For purpos...

We investigate the nature of the superconducting current from the Maxwell’s displacement current. We argue that the conduction current density term of the Maxwell’s equations is physically untrue, and it should be eliminated from the equations. Essentially, both the superconducting current and conduction current are originated from the Maxwell’s displacement current characterizing the changes o...
