Estimate of sediment load is required in a wide spectrum of water resources engineering problems. The nonlinear nature of suspended sediment load series necessitates the utilization of nonlinear methods to simulate the suspended sediment load. In this study Artificial Neural Networks (ANNs) are employed to estimate daily suspended sediment load. Two different ANN algorithms, Multi Layer Perce...

Nowadays, one of the most significant problems is that to recognize how severity heavy precipitation and floods may alter in future time comparison with current period. The purpose this research understand impact climate change on storm water probability maximum flood for Zayandeh rud river basin Iran selected as a case study. Forecast climatic parameters based temperature upcoming period (2006...

there are different materials and compounds in water that determine its chemical and physical quality. as the result of special conditions such as increase and decrease in discharge, water quality can vary. one of these conditions is drought that decreases discharge, and water quality changes. in this study, droughts of sistan and baluchistan province have been analyzed using standardized preci...

BACKGROUND Knowledge about the most recent HIV epidemic among young generation in Thailand is crucial for improving the prevention programs. It is important to distinguish between recent and long-term HIV-1 infections among the sero-surveillance populations to estimate the HIV-1 incidence. OBJECTIVE To obtain the HIV-1 incidence estimates in young Thai men from the HIV-1 sero-surveillance amo...

BACKGROUND Dialysis-requiring acute kidney injury (AKI) is associated with substantial mortality and risk of end-stage renal disease (ESRD). Despite considerable growth in incidence of severe AKI, information pertaining to trends in outcomes remains limited. We evaluated time trends in one year risks of ESRD and death in patients with dialysis-requiring AKI over an eight year period in Denmark....

abstract striped rice stem borer, chilo suppressalis walker (lepidoptera: pyralidae) is a major pest of rice in northern iran. regarding to the importance of population dynamics studies in pest management programs, the population fluctuations of c. suppressalis was studied in central part of mazandaran province (rice research centre of mazandaran) during 2005-2006. the male and female moths wer...

The aim of this study was to assess the evolution of survival in patients treated surgically for non-small cell lung cancer (NSCLC) between 2005 and 2012.From January 2005 to December 2012, 34 006 patients underwent pulmonary resection for NSCLC and were included in the French national database Epithor. Patients' characteristics, procedures and survival were analysed. Survival according to the ...
