Background Calls for evidence-informed public health policy, with implicit promises of greater program effectiveness, have intensified recently. The methods to produce such policies are not self-evident, requiring a conciliation of values and norms between policy-makers and evidence producers. In particular, the translation of uncertainty from empirical research findings, particularly issues of...

Water pH and active ingredient concentration are two of the most important variables to consider in the manufacturing process of fungicides. If these variables do not meet the required standards, the quality of the product may be compromised and lead to poor fungicide performance when water is used as the application carrier, which is in most cases. Given the correlation between the variable...

pyridostigmine bromide (pb) is a reversible cholinesterase inhibitor. the aim of this study was to determine the effect of orally administration of single dose sustained-released tablet of pyridostigmine bromide (pbsr) on the frequency domain indices of heart rate variability (hrv). thirty-two healthy young men were participated in this study. they were divided into 2 groups; the pyridostigmine...

there is a need to analyze and map rainfall erosivity to assess soil erosion at the regional scale. the objectives of this study were to develop a regional model to estimate seasonal erosivity from seasonal rainfall data and to study temporal and spatial distribution of rainfall erosivity for the gorganrood drainage basin in the northeast of iran. six gauging stations with a high temporal reso...

the objective of the article is to investigate the variability in growth and wood properties of the willow clones. the growth and wood traits of four year old 21 clones willow clones were investigated. analysis of variance showed that willow clones differed significantly for all the studied growth and wood traits. among the growth parameters the maximum heritability value was shown by height wh...

in this paper, a sensitivity analysis of artificial neural networks (nns) is presented and employed for estimating the patch load resistance of plate girders subjected to patch loading. to evaluate the accuracy of the proposed nn model, the results are compared with the previously proposed empirical models, so that we can estimate the resistance of plate girders subjected to patch loading. the ...

objective: the aim of this study was to estimate genetic variability and phonetic relationships of 50 isolates of p. sojae from iran. methods: during 2005–2007, 142 isolates of phytophthora sojae were collected from soil samples and diseased soybean plants from lorestan, mazandaran, golestan and ardabil provinces. races of the isolates were determined. dna of p. sojae fifty isolates was amplifi...

Estimating the amount of variation due to spatial dependence at different scales provides a basis for designing effective experiments. Accurate knowledge of spatial structures is needed to inform silvicultural guidelines and management decisions for long term sustainability of forests. Furthermore, geostatistics is a useful tool to describe and draw map the spatial variability and estimation o...

Immunosuppressants require therapeutic drug monitoring because of their narrow therapeutic index and significant inter-individual variability in blood concentrations. This variability can be because of factors like drug-nutrient interactions, drug-disease interactions, renal-insufficiency, inflammation and infection, gender, age, polymorphism and liver mass. Drug monitoring is widely practiced ...
