background: the appropriate colon cleansing is a major determinant of quality of colonoscopy. the aim of this study was to compare the efficacy and tolerability of the morning (am) peg (polyethylene glycol) solution to previous-evening (pm) peg solution for the afternoon colonoscopy. methods: this comparative study compared the am to pm prep for afternoon outpatient colonoscopy. the subjects ra...

PURPOSE The objectives of the study were to use the International Atomic Energy Agency (IAEA) software package for the analysis of scintigraphic renal dynamic studies to obtain values of curve parameters and excretory parameters in children with hydronephrosis and to validate the reliability of these numerical outputs by comparing with values established by consensus reports. PATIENTS AND MET...

BACKGROUND AND OBJECTIVES: The Bangladesh government declared a general holiday beginning on March 26, 2020 aimed to combat coronavirus (COVID-19) pandemic. The aim of this study was to assess the impacts of the general holiday on air quality in Dhaka city area of Bangladesh. METHODS: Hourly PM2.5 (aer...

In recent years, the haze occurs frequently and air pollution is getting worse in Beijing-TianjinHebei Region, China. The particulate matter pollution characteristic researches are playing a significant role especially in the districts where have higher concentration PM and air pollution. In this study, we collected daily particulate matter (PM10, PM2.5) mass concentration data from 7 air pollu...

The analysis of cruise ships is focusing on port areas where they may represent a significant source anthropogenic emissions. In order to determine the correlation between ship activities (hoteling and maneuvering) in ports with ambient concentration pollutants associated marine diesel fuel combustion, low-cost sensors are finding their market share due lower prices compared referent ones. this...

We compare the peak optical luminosity with orbital period for a sample of 22 stellar-mass black hole candidates good measurements both quantities. find that absolute magnitude outbursts follows linear relation $M_{V,peak}=3.48 (\pm 0.85)-3.89 0.91) {\rm log}P_{orb}$, which corresponds to $L_V \propto P_{orb}^{1.56\pm 0.36}$ power law relation. Excluding V4641 Sgr is strong outlier and not like...

An efficient, sensitive and fast stopped-flow method has been developed to determine asulam in water, based on its inhibition effect on the horseradish peroxidase-luminol-hydrogen peroxide chemiluminescence reaction, (HRP-luminol-H(2)O(2)). Ultra fast data acquisition (0.20s) facilitates excellent selectivity because no interferences from concomitants in the matrix act in such short time scale....

In the present study relationship between shrimp catch per unit effort (CPUE) and satellite-based environmental parameters, chlorophyll-a (Chl-a) and sea surface temperature (SST), was investigated in 27 stations in Bushehr provincial waters in the geographical position from E 50˚ 44´ and N 28˚ 59´ to E 51˚ 40´ and N 27˚ 33´, in July 2017 and July 2018. SST and Chl-a data were extracted from +E...
