Background: The energy crisis is a growing problem around the world, requiring creation of alternative sources that can generate less carbon dioxide and benefit ecosystem. Reutilization wastewater becoming emerging solution. Wastewater contains large amount organic matter be oxidized in microbial fuel cells (MFCs) to produce electricity. MFCs use biodegradable materials create presence microorg...

introduction: urine morphine test, in several countries is the most primarily available qualitative test for detecting opioid abusers. since the users of illicit drugs attempt to defeat urine tests and there are also plenty of claims that usage of hd (high dose) contraceptive pills can result in false-negative results, we decided to design the present study to investigate the probable in vitro ...

A supramolecular probe is designed for visual detection of potassium based on a novel cyanine dye aggregate recognizing the motif transition of telomeric G-quadruplexes under the Na(+) background. The practical application for colorimetric measurement of urine potassium has been tested.

In this letter, we consider static black hole in f(R) gravity.We take advantage from corrected entropy and temperature and investigate such black hole. Finally, we study the $ P - V $ critically and phase transition of corrected black hole with respect to entropy and temperature. Here also, we obtain the heat capacity for the static black hole in $ f(R) $ gravity. This calculation help us...

BACKGROUND Many clinical practice guidelines encourage diagnosis and empiric treatment of lower urinary tract infection without laboratory investigation; however, urine culture testing remains one of the largest volume tests in the clinical microbiology laboratory. In this study, we sought to determine if there were specific patient groups to which increased testing was directed. To do so, we c...

Background: Black pepper (Piper nigrum) is mainly cultivated in tropical areas such as South India. It is known as a popular spice in all over the world. Although some studies have been carried out to determine the ingredients of black pepper Essential Oil (EO) cultivated in various regions of the world, but there is little data about some physicochemical characteristics of EO of black pepper c...
