In this paper, the purpose is to improve the efficiency of triple-junction solar cell by introducing quantum well into GaAs junction. Firstly, InGaP/GaAs/InGaAs triple-junctions solar cell has been simulated. Then, a multiple stepped quantum wells (MSQWs), in which InGaAs well is sandwiched by InGaAsP as stepped layer, and the barrier is GaAs, has been introduced into intrinsic region of single...
We study tunneling conductance of a graphene based normal metal-insulator-superconductor (NIS) junction with Corbino disk structure. Solving Dirac-Bogolioubov- De Gennes (DBdG) equation in different regions of the junction and employing scattering approach we obtain normal and Andreev reflection coefficients of the junction. Using Blonder-Tinkham-Klapwijk (BTK) formula we calculate tunneling co...
OBJECTIVE To analyze the management of prenatal urinoma and ureteropelvic junction obstruction (UPJO) postnatally by a case report and literature review. METHODS We report a case of an UPJO and urinoma in a newborn. After birth, renal function was absent, and nephrectomy was performed. The literature from 1985 to date has been reviewed. DISCUSSION By the analysis of the literature, we can o...
Effects of Doxycycline on Cx43 Distribution and Cardiac Arrhythmia Susceptibility of Rats after Myocardial Infarction Abstract: This study aimed to observe the effects of doxycycline (DOX) on gap junction remodeling after MI and the susceptibility of rats to cardiac arrhythmia. The proximal left anterior descending coronary artery of rats was ligated to establish a myocardial infarction animal...
The development of oxytocin (OT) sensitivity in the parturient uterus is associated with increases in myometrial OT receptor concentration, gap junction formation, and prostaglandin (PG) production. To investigate whether PGs mediate these responses, we measured OT responsiveness, OT receptor concentrations, and gap junction formations in uteri of Day 19, 20, 21, 22, 23 pregnant and Day 2 postp...
OBJECTIVES To assess retrospectively the subjective and objective outcomes achieved after laparoscopic treatment for ureteropelvic junction obstruction at our institutions. METHODS Between August 1999 and July 2001, 19 patients (11 women and 8 men), with a mean age of 31.2 years (range 17 to 67), underwent laparoscopic treatment for ureteropelvic junction obstruction. Of these, 17 patients we...
Esophagogastric junction (EGJ) adenocarcinomas are usually classified into one of the three categories of the Siewert system. The clinicopathological features of EGJ adenocarcinomas vary according to this classification scheme. The lymphatic flow in EGJ tumors of any type is mainly toward the abdomen, and nodal metastasis to the upper or middle mediastinum from Siewert type II or III tumors is ...
