A large number of binder ingredients such as cement and active mineral admixtures are used in the preparation high-strength concrete, water:binder ratio is extremely low. This leads to a amount shrinkage concrete at early stage curing, which poses great threat safety durability structure. To solve cracking problem induced by high shrinkage, we choose change admixture it. In this study, high-per...
Introduction: Identification of the factors related to non-alcoholic fatty liver disease in children and adolescents help us to know appropriate methods for prevention and control of chronic diseases. Methods: This cross-sectional and analytic study comprised 962 children and adolescents, aged 6-18 years, in Isfahan in 2008. Variables related to life style and metabolic syndromes related...
Array processing of seismic data provides a powerful tool for source location and identification. For this method to work to its fullest potential, accurate transduction of the unadulterated source mechanism is required. In our tests, controlled areas of normal-strength concrete specimens were exposed to a low relative humidity at an early age to induce cracking due to drying shrinkage. The spe...
Purpose: Surrogate endpoints are needed that correlate with overall survival (OS). We analyzed individual patient tumor data from a phase III trial of vemurafenib versus dacarbazine (BRIM3) to identify criteria for tumor measures that correlated with OS. Correlates were validated using a separate data set from a phase II trial of vemurafenib (BRIM2). Experimental Design: Deidentified tumor meas...
Protein energy malnutrition is associated with cerebral atrophy which may be detrimental to intellectual development. The aim of this study was to document the anatomical abnormalities which lead to the appearance of cerebral atrophy using magnetic resonance imaging (MRI) in the acute stage of kwashiorkor and to monitor changes during nutritional rehabilitation. Twelve children aged 6 to 37 mon...
