buildings with wall or frame-wall systems are more effective against earthquake forces and sustain less damage than buildings which their lateral resistance is solely depends on frames. four reinforced concrete (rc) structural wall specimens were subjected to cyclic loading using finite elements method with abaqus software in order to study influence of diagonal web reinforcement. the research ...

Fiber reinforced polymer (FRP) material is currently being produced in different configurations and widely used to strengthen and retrofit concrete structures and bridges. It is also possible to apply other strengthening methods without changing the appearance or the dimensions of the structure. Near Surface Mounted (NSM) is a recent strengthening method using CFRP bars (rods or laminate strips...

BACKGROUND Respiratory muscle training has been shown to improve both its strength and endurance. The effect of these improvements on whole-body exercise performance remains controversial. OBJECTIVE To assess the effect of a 10 week inspiratory resistive loading (IRL) intervention on respiratory muscle performance and whole-body exercise endurance. METHODS Fifteen apparently healthy subject...

Iron oxide nanoparticles (magnetite (Fe3O4), hematite (Fe2O3)) have been received increasing attention in drug and gene delivery. In this work, water-base double layer functionalized iron oxide nanoparticles (DL-IONPs) were designed and prepared of a biodegradable, biocompatible carrier by co-precipitation method with high DNA loading capacity due to self-assembly of a second organic layer. The...

upflow anaerobic sludge blanket (uasb) reactors have been widely used for treatment of industrial wastewater. in this study, performance of a lab-scale up-flow anaerobic sludge blanket (uasb) reactor, treating a chemical synthesis-based pharmaceutical wastewater, was evaluated under different operating conditions. a (p.e) pipe with a diameter of 250 mm and total height of 120 cm and effective h...

Postural tachycardia syndrome (POTS) is associated with exercise intolerance, hypovolemia, and cardiac atrophy, which may contribute to reduced stroke volume and compensatory exaggerated heart rate (HR) increases. Acute volume loading with intravenous (iv) saline reduces HR and improves orthostatic tolerance and symptoms in POTS, but its effect on exercise capacity is unknown. In this study, we...

Palm-based lipid nanoparticle formulation loaded with griseofulvin was prepared by hot homogenisation and a solvent-free method. The optimum griseofulvin loaded lipid nanoparticles were prepared via stages of optimisation, such as high pressure homogenisation (HPH) parameters, lipid and surfactant screening and selection of suitable lipid to surfactant ratios; followed by photon correlation stu...

The intensive acute exercises results in too much oxygen consumption and hence produce excessive free radicals and damage of tissues. This study was conducted to investigate the effects of thyme tea on free radical formation and antioxidant system. Eighteen elite volunteer wrestlers joined the study. The wrestlers were randomly divided into two groups to from experiment and control groups. The ...

This paper reports the results of model loading tests performed on an eccentrically loaded strip foundation supported by multi-layered geogrid-reinforced sand. Only one type of geogrid and sand at one relative density of compaction were considered. Based on the present laboratory test results, an empirical relationship for the reduction factor has been developed. This relationship can be used t...
