An extended experimental campaign was conducted to analyse the evolution of UHPC tensile performance over time as affected by sustained flexural load and aggressive environments both interacting with its autogenous self-healing capacity. A new methodology including destructive non-destructive tests proposed. Three different mix designs were tested, steel fibres, crystalline admixture, various n...

This study investigates the effectiveness of hybrid fibers (steel and macro-synthetic) on shear behavior prestressed concrete beams. The fiber combination was selected to avoid workability issues at high volume dosages ensure effective crack arresting over opening range. Fracture studies included testing notched prisms identify role in bridging mechanism. Seven reinforced (HFRPC) beams were tes...

Fiber reinforced polymer (FRP) has been proved to be effective improve the structural strength and ductility for column structures. An experimental study was conducted investigate compressive performance of FRP confined glued-laminated timber (GLT) cross-laminated (CLT) columns. A total 60 specimens two dimensions in height using different types, thickness, laminate types were tested under cycl...

To determine whether the variation in the magnitude of work load sustained by the left and right ventricles during adulthood and senescence affects the load-dependent aspect of relaxation, posterior papillary muscles from the left and right ventricles of rats at 4, 10, and 20 months of age were studied under variably loaded conditions in vitro. Because of differences between the life spans of F...

In asthmatic patients, either bronchodilatation or bronchoconstriction may develop during exercise. In 18 patients with mild-to-moderate asthma, we conducted two studies with the aims to 1) quantify the bronchodilator effect of hyperpnea induced by incremental-load maximum exercise compared with effects of inhaled albuterol (study 1, n=10) and 2) determine the time course of changes in airway c...

It is now well established that natural populations of Drosophila melanogaster harbor substantial genetic variation associated with physiological measures of immune function. In no case, however, have intermediate measures of immune function, such as transcriptional activity of immune-related genes, been tested as mediators of phenotypic variation in immunity. In this study, we measured bacteri...

results patients who attained sustained virological response had a less risk (85%) for all-cause mortality and about 63% reduced risk of hepatocellular carcinoma incidence than those who did not achieve sustained virological response. based on deeply analysis, the stage of liver fibrosis was a risk factor at baseline for the incidence of hepatocellular carcinoma. conclusions sustained virologic...
