Multijunction solar cells must be electrically isolated from one to another at the end of fabrication process; a step known as mesa isolation. In this study, three different techniques are assessed perform step: saw-dicing, wet etching and plasma etching. Triple junction were fabricated with each process open-circuit voltages measured in order compare impact technique on device performance. An ...

introduction: cardiac glycosides such as digoxin or digitoxin are the natural products that are traditionally used to increase cardiac contractile force in patients with heart failure and cardiac arrhythmias. it has been shown that digoxin can directly inhibit the cell proliferation and lead to cell apoptosis. present study was conducted to analyze the effect of digoxin in the cohorts of mesenc...

conclusions the findings of this study are consistent with the hypothesis that local, systemic, or tumor-induced immunosuppression may allow the mcpyv to initiate skin aggressive cancer. it is necessary to maintain regular check over patients taking immunosuppressive medications for mcpyv infection. since there is not any information about detection and molecular biology analysis of mcpyv among...

epilepsy as one of the most common neurological disorders affects more than 50 million people worldwide with a higher prevalence rate in low-income countries. excessive electrical discharges in neurons following neural cell damage or loss cause recurrent seizures. one of the most common and difficult to treat types of epilepsy is temporal lobe epilepsy (tle) which results from hippocampal scler...

Two issues regarding the arousal-performance relationship in sport were addressed in this study: the relationship between task complexity, optimal arousal, and maximal performance, and the appropriateness of using various measures of performance. Data were collected from high school athletes (n=51) across four track and field meets. State anxiety was obtained prior to each performance and three...

The research described here focuses on global tempo transformations of monophonic recordings of saxophone jazz performances. We have investigated the problem of how a performance played at a particular tempo can be automatically rendered at another tempo while preserving its expressivity. That is, listeners should not be able to notice, from the expressivity of a performance, that has been scal...

Performance in discriminating rotated 'same' patterns from 'different' patterns may decrease with rotation angle up to about 90 degrees and then increase with angle up to 180 degrees. This anomalously improved performance under 180 degrees pattern rotation or point-inversion can be explained by assuming that patterns are internally represented in terms of local features and their spatial-order ...

One of the most widely known solar thermal applications is solar water heating. In terms of installation expenditures and energy cost over the total life of the system, solar water heating technology has proven to be cost efficient for several domestic and industrial applications. Technological practicability of these systems has long been recognized and is presently employed in commercial sect...

The sensing capabilities of zinc oxide nano/micro-structures have been widely investigated and these structures are frequently used in the fabrication of cutting-edge sensors. However, to date, little attention has been paid to the multi-sensing abilities of this material. In this work, we present an efficient multisensor based on a single zinc oxide microwire/gold junction. The device is able ...
