The aim of this research work is to investigate the efficiency newly developed Natural Fiber Rope Reinforced Polymer (NFRRP) composites enhance shear strength reinforced concrete (RC) beams. Two types NFRRP were made using low-cost hemp and cotton fiber ropes. effectiveness confinement in increasing shear, energy dissipation, deformation capacities beams was studied. effect these natural ropes ...

This study analyzes microphysical signatures relevant to the short-cycle lightning activity in inner core of Typhoon Hato (2017) before landfall China. Observations reveal that bursts were accompanied by enhanced inner-core convection with a behavior cycle about 3 hr. The coupling between wavenumber-2 vortex Rossby waves (VRWs) and shear-forced convective asymmetries resulted local updraft enha...

The effect of two antimicrobials in the enhancement solution was investigated in this study. Sensory and shelf-life characteristics were measured for beef top rounds enhanced to 110% with 0.5% sodium chloride and 0.4% sodium tripolyphosphate (CNT); CNT with a 1% solution of 80% sodium citrate plus 20% sodium diacetate (SC + D); or CNT with 2% buffered vinegar (VIN) in the final product. SC + D ...

Ground-based and airborne Doppler radar data collected during passage of frontal rainstorms over the European Alps and Cascade Mountains of Oregon are found to exhibit characteristic cross-barrier flow and precipitation patterns. A stably stratified layer of blocked (or partially blocked) low-momentum flow below mountain-crest level is separated from strong cross-barrier flow aloft by a concent...

The stretching of fluid elements and the dynamics of mixing are studied for a variety of polymer solutions in nearly two-dimensional magnetically driven flows, in order to distinguish between the effects of viscoelasticity and shear thinning. Viscoelasticity alone is found to suppress stretching and mixing mildly, in agreement with some previous experiments on time-periodic flows. On the other ...

The present study investigated comparatively the impact of two types of input enhancement (i.e. textual vs. compound enhancement) on developing grammar ability in Iranian EFL setting. Sixty-five female secondary high school students were selected as a homogenous sample out of about a 100-member population based on Nelson language proficiency test. Then, their grammar ability was measured based ...

In order for site-directed polymer ultrasound contrast agents (UCAs) to provide acoustic enhancement at disease sites to distinguish normal tissue from diseased tissue, the surface of these agents must be functionalized with mixtures of grafted polymers. Here a combination of longer liganded polyethylene glycol (PEG)-lipids and shorter unliganded PEG-lipids were introduced into the oil phase of...

There is much current interest in modelling suspensions of algae and other microorganisms for biotechnological exploitation, and many bioreactors are of tubular design. Using generalized Taylor dispersion theory, we develop a population-level swimming-advection-diffusion model for suspensions of micro-organisms in a vertical pipe flow. In particular, a combination of gravitational and viscous t...
