thechah nimeh reservoirs of sistan is as one of the main water sources of zabol city used for drinking, agriculture, industry and livestock purposes. this study aimed to determine the contribution of the natural and concentration factors of heavy metals such as cd, pb and cu in sediment of chah nimeh of sistan. the concentrations of heavy metals in surface sediments were studied in six stations...

conclusions the prevalence of predominant breastfeeding during the first month postpartum is high in shahroud. interventions to strengthen adherence to who guidelines for breastfeeding should be considered. breastfeeding education providers at the hospitals should emphasize the effects of formula on breastfeeding continuation at early postpartum. background the introduction of fluids to infants...

objective about 1 % of infants are of very low birth weight. however, they comprise about 50% of infant mortality. we compare the effects of continuous versus intermittent feeding on physical growth, gastrointestinal tolerance and macronutrient retention in low birth weight infants (methods a prospective randomized trial clinical trial was performed from 2004-2005. very low birth weight neonate...

A systematic study of the effect of fragment−fragment interaction, quantum statistics, γ-feeding and collective flow is made in the extraction of the nuclear temperature from the double ratio of the isotopic yields in the statistical model of one-step (Prompt) multifragmentation. Temperature is also extracted from the isotope yield ratios generated in the sequential binary-decay model. Comparis...

This paper depicts a wideband circularly polarized (CP) antenna for 5G devices. The array has 3D structure including four simple printed dipole elements with directional radiations, high gain, and efficiency. It achieves CP by using the sequential rotation (SR) feeding based on 90°-3dB hybrid couplers in proposed network. bandwidth is wide, 26.7%, an operating frequency band from 3.35 GHz to 4....

CePO(4) nanorods decorated with QDs (QDs@CePO(4)) can be prepared in a sequential, aqueous procedure under continuous flow using a rotating tube processor and a narrow channel reactor. The emission from the QD@CePO(4) is tunable from green to red by simply adjusting the feeding rate, which in turn regulates the particle size of the QDs. The Ce(3+) ions in the QDs@CePO(4) serve as an efficient f...

we analyze a sequential decision making process, in which at each stepthe decision is made in two stages. in the rst stage a partially optimalaction is chosen, which allows the decision maker to learn how to improveit under the new environment. we show how inertia (cost of changing)may lead the process to converge to a routine where no further changesare made. we illustrate our scheme with som...
