reactive powder concrete (rpc) is an ultra high performance concrete which has superior mechanical and physical properties. the rpc is composed of cement and very fine powders such as crushed quartz (100–600 μm) and silica fume with very low water/binder ratio (w/b) (less than 0.20) and super plasticizer (sp). the rpc has a very high compressive and tensile strength with better durability prope...

objective : this study aims to describe the blood pressure profile of newborns of preeclampsia mothers in vali-e-asr hospital during 2003-2004. materials and methods : in this cross-sectional descriptive analytical study 200 mothers and their newborns were studied. blood pressure of all newborns was checked by oscillometric method on the first day after birth and recorded in a questionnaire alo...

in the course of this study, empirical models were developed for the pressure-density relationship in a large cubic baler for baling alfalfa and barley straw. least squares regression analysis was employed to develop the empirical model and estimate the model coefficients by minimizing the summation of the squared differences between data resulting from the developed empirical model and the cor...

background: the global health burden has faced toward non-communicable diseases (ncds). it is suggested that adulthood blood pressure (bp) is tracked from childhood. this study aims to evaluate the mean bp and the prevalence of prehypertension and hypertension in the iranian pediatric population. methods: in a national survey as the 4th phase of childhood and adolescence surveillance and preven...

BACKGROUND Intracerebral hemorrhage is associated with poor clinical outcome and high mortality. Research and treatment modalities have focused on the expansion of the primary hematoma through blood pressure control and activation of coagulation factors. However, clinical trials have failed to show decreased rates of death or disability in intracerebral hemorrhage following hospital initiation ...

OBJECTIVES To evaluate if pre-pregnancy body mass index (BMI) determines blood pressure throughout pregnancy and to explore the role of gestational weight gain in this association. In addition, the effects of pre-pregnancy BMI and gestational weight gain on the occurrence of gestational hypertension and pre-eclampsia were investigated. DESIGN Prospective cohort study. SETTING Maternal and c...
