Rainfall- runoff modeling and river discharge forecasting are an important step toward flood management and control, design of hydraulic structures in basins and drought management. The purpose of this study was simulating the daily flows in the Navrud watershed using WetSpa model. WetSpa is a hydrological- physical model that can predict flood on the watershed scale with different time steps. ...
Background & Objectives: Timely response to emerging diseases and outbreaks are a major public health and health systems priority. There are few published studies that evaluate the performance of cumulative sum (CUSUM) on identical data using semi- synthetic simulation approach. This study was undertaken to determine the performance of the CUSUM in timely detection of 831 days of simulated outb...
OBJECTIVES Several studies identified a heterogeneous impact of heat on mortality in hot and cool regions during a fixed period, whereas less evidence is available for changes in risk over time due to climate change in these regions. We compared changes in risk during periods without (1996-2000) and with (2008-2012) heatwave warning forecasts in regions of South Korea with different climates. ...
effects of short terms starvation periods on body composition in rainbow trout (oncorhynchus mykiss)
in aquaculture, fishes might experience periods of food deprivation during pre-harvesting, transporting and sorting. in during starvation, some fish utilize muscle protein as a major energy source and some fish utilize primarily lipids. with respect to vital role of starvation periods on body composition, the current study was carried out for one month in autumn 2010 at research farm of isfahan...
statement of the problem: dental caries is the most common disease of childhood. using probiotics has recently been introduced to reduce the incidence of dental caries.it consists of live microbial food supplements that beneficially affect the host, and hence are considered an alternative way to eradicate the infections. purpose: the aim of this study is to evaluate the effect of consumption of...
In this paper we investigate cross-commodity futures markets connectedness over different nearest-to-maturities. We thus implement time and time-frequency estimations for two constructed baskets of commodities, classified based on common delivery months. Using daily data spanning the period 1995–2020, provide a set stylized facts extent to which commodity are integrated or segmented. More speci...
Background & Aim: Job stress can interfere with endocrine function and result in dysfunctional menstrual bleeding patterns. The aim of this study was to assess the relationship between job stress with menstrual bleeding pattern among midwives. Methods & Materials: In this cross-sectional study, we recruited 150 midwives working in hospitals and health centers of Mashhad using two-stage sampl...
objective: the objective of this study was to investigate the invitro fluoride release of four new self-adhesive resin cements; set (sdi, australia), breeze (pentron, usa), embrace wetbond (pulpdent, usa), g-cem (gc, japan) and to assess the bonding performance of these self-adhesive resin cements for bonding of orthodontic brackets. materials and methods: for fluoride release experiment, six ...
