The objective of this study was to estimate variance components and genetic parameters for growth curve parameters in Shall sheep. Studied traits were parameters of Brody growth model which included A (asymptotic mature weight), B (initial animal weight) and K (maturation rate). The data set and pedigree information used in this study were obtained from the Animal Breeding Center of Iran and co...

Calculations of sensitivities of future experiments are a necessary ingredient in experimental high energy physics. Especially in the context of measurements of the neutrino oscillation parameters extensive studies are performed to arrive at the optimal configuration. In this note we clarify the definition of sensitivity as often applied in these studies. In addition we examine two of the most ...

conclusions we can conclude that the surveillance presented to our injured group probably had some defects that need to be revised in therapeutic services to enhance survival requirements. objectives the aim of this study was to evaluate the outcome of trauma cases using the trauma score and the injury severity score (triss) model and then comparing this with the results of a major trauma outco...

in the present study, effect of five isolates of trichoderma harzianum on growth parameters of tomato was carried out as cr design with six replications under greenhouse conditions. the concentrations 0.5%, 1% and 1.5% inoculums per pot were used. plant length, shoot and root fresh/dry weight, number of leaves and stem diameter as growth parameters were measured. the results showed that isolate...

Growth and death are both fundamental macroscopic properties for all living matters, and thus cell division and mortality rates are good parameters for characterizing cellular physiology in a given environment. While population growth rates in various conditions have been reported in literature, death rate is rarely measured, especially in favorable culture conditions where cells grow exponenti...

the beet armyworm (spodoptera exigua hübner) is an important pest of many agricultural crops all over the world. most of the sugar beet growing regions in iran are infested. in this study, the acute lethal effects of pyriproxyfen, spinosad, and indoxacarb as well as sublethal effects of pyriproxyfen on the 1st instar s. exigua were assessed by leaf dip bioassay method. mortality was recorded 48...

introduction: causes of death vary globally, and they depend regionally on lifestyle and socio-cultural factors. the purpose of this study was to determine accident-related mortality in southern khorasan province, iran, in the year 2010.  methods: this descriptive-analytical study involved all the death cases in the year 2010 in southern khorasan. the data were collected from the death registra...

A compilation of values for the exponential coefficient of natural mortality (M) is given for 175 different stocks of fish distributed in 84 species, hath freshwater and marine, and ranging from polar to tropical waters. Values of Loo(LT, em), W",,(g, fresh weight), K (l/year) and T (ec, mean annual water temperature) were attributed to each value of M, and the 175 sets of values plotted such t...

BACKGROUND/AIMS Pregnancy-associated plasma protein A (PAPP-A) is a biomarker related to vascular damage. The aim of the study was to focus on PAPP-A and related parameters and their relationship to the prognosis of long-term hemodialysis (HD) patients. METHODS This is a prospective observational cohort study which included 261 long-term HD patients followed up for 5 years and 66 healthy subj...
