[1] Understanding and quantifying the long-term suspended sediment discharge of drainage basins is a key goal of geomorphology, with important implications for the study of water quality, agricultural sustainability, and the evolution of landscapes and sedimentary basins over geologic timescales. Previous studies have highlighted the importance of relief/slope, precipitation, temperature, veget...
BACKGROUND Despite significant investments of federal and state dollars to transition patient medical records to an all-electronic system, a chasm still exists between health care quality and payment for it. A major reason for this gap is the difficulty in evaluating health care outcomes based on claims data. Since both payers and patients may not appreciate how illness complexity impacts treat...
The present study analysed the relationship between catch amounts of the Clupeidae species and monthly average weather temperature, rainfall, wave high and water depth in the southwestern of Caspian Sea. The data from two maritime consecutive years gathered by means of industrial fishing vessel were used in the data analysis. The results showed that the correlation between monthly average water...
In this study, simple and multiple regression models were developed to estimate the monthly average daily global solar radiation in Lawra, Ghana using ground measurement of horizontal irradiance (Nov 2020–May 2022) typical meteorological year (TMY) data (Jan 2017–Dec 2019). Various predictor variables such as sunshine ratio, minimum relative humidity maximum temperature etc. correlated from TMY...
In a watershed, sediment arises due to the erosion and some factors such as pastures destruction,change users, no reasonable cultivation. That causes problems such as sedimentation in reservoirs andreduces their useful volume, reducing water quality in agricultural consumption; reduce the efficiencyof hydraulic structures and some other environmental problems. Changes in sediment load in a rive...
Ozone has adverse effects on human health, it is necessary to obtain the refined ozone exposure concentration. At present, most of existing research based ground air quality monitoring station (MS) which gather urban area information only. It diffcult estimate in areas where MSs are scarce. By combining accurate but uneven data outdoor concentrations and unbiased coverage RS China, we can impro...
BACKGROUND China has the highest incidence of hemorrhagic fever with renal syndrome (HFRS) worldwide. Reported cases account for 90% of the total number of global cases. By 2010, approximately 1.4 million HFRS cases had been reported in China. This study aimed to explore the effect of the rodent reservoir, and natural and socioeconomic variables, on the transmission pattern of HFRS. METHODOLO...
