Creep and shrinkage are such properties that will occur in concrete when they are under load and exposed to surrounding. Since this property will cause deformation which may decrease the design strength of the concrete, it is necessary to do have more knowledge on this phenomenon. So, we will study the effect of creep on 7 and 14 days of cured time of specimens which sealed or unsealed will be ...

In this research, an attempt was made to find the permeability of RC beam with AFRP by making use hydraulic conductivity test and a double-ring infiltrometer. Based on state-of-the-art methodology, three different samples, Kelvar 29, 49 149, were considered as laminates prevent deflection beams. Accelerated corrosion carried out using impressed current, induced calculated galvanostatic method. ...

A 44-year-old man with chronic hepatitis C received three courses of interferon (IFN) therapy. HCVgenotype was lb, viral load was 1,200 kcopies/ml and interferon sensitivity determining region (ISDR) was the intermediate type before the 1st IFN therapy. The 1st and 2nd IFN therapies resulted in failure to yield a sustained response. Seven years after from the 1st therapy, viral load had decreas...

OBJECTIVE To assess the effect of transient and sustained variations in cardiac load on the values of the end-systolic pressure-diameter relation (ESPDR) of the left ventricle. METHODS We studied 13 dogs under general anesthesia and autonomic blockade. Variations of cardiac loads were done by elevation of blood pressure by mechanical constriction of the aorta. Two protocols were used in each ...

In humans, inspiratory constraints engage cortical networks involving the supplementary motor area. Functional magnetic resonance imaging (fMRI) shows that the spread and intensity of the corresponding respiratory-related cortical activation dramatically decrease when a discrete load becomes sustained. This has been interpreted as reflecting motor cortical reorganization and automatisation, but...
