This study conducts a life cycle assessment (LCA) of carbon emissions for recycled fine aggregate (RFA) concrete. There were six stages involved in the RFA, including raw material extraction and processing, transportation to manufacture, RFA concrete manufacturing, building site, construction, de-construction or demolition. The uptake effect, due carbonation concrete, was also considered. conce...

  Abstract   Objective: The aim of this study was to evaluate the efficacy of antibiotic-loaded bone   cement in controlling local infection and in regard to its physical characteristics, elastic   modulus, and tensile strength in-vitro.   Methods: Acrylic bone cement, based on polymethylmethacrylate (PMMA) was   mixed with the powder form of three antibiotics, i.e., gentamicin, tobramycin, and...

In his recent publication of a NN phase shift analysis below 160 MeV, Henneck reports relatively large values for the mixing parameter ǫ1. Based on these results, Henneck suggests that the strength of the ρ-meson tensor coupling to the nucleon may be weaker than used in present day NN interactions, like the Paris or Bonn potentials. We point out that at low energies ( ∼ 100 MeV) there is very l...

The use of reclaimed asphalt pavement (RAP) to create recycled mixture is attracting great interest because landfill space decrease and natural resources saving. Also, incorporating rejuvenators an effective method promote the utilization RAP materials in hot mix (HMA) production. main goal this study was evaluate effect Cyclogen vacuum bottom (VB) on performance mixtures against moisture sensi...

An organism's behavioral decisions often depend upon the relative strength of appetitive and aversive sensory stimuli, the relative sensitivity to which can be modified by internal states like hunger. However, whether sensitivity to such opposing influences is modulated in a unidirectional or bidirectional manner is not clear. Starved flies exhibit increased sugar and decreased bitter sensitivi...

The present experimental research investigates the feasibility of partial substitution of styrene-butadiene-styrene (SBS) with ground granulated blast-furnace slag (GGBS) for the modification of bitumen and porous asphalt mixtures. The control asphalt mixture and the seven modified porous asphalt mixtures have been analyzed separately and their performance was compared. Modified bitumen and asp...

Clouds play a crucial role in Earth’s radiative budget, yet their climate feedbacks are poorly understood. The advent of space-borne high resolution spectrometers probing the O2 A band, like GOSAT and OCO-2, could make it possible to simultaneously retrieve vertically resolved cloud parameters that play a vital role in Earth’s radiative budget, thereby allowing a reduction of the corresponding ...

342 injections (380,,) in the placebo group; the higher incidence of local reactions in the placebo group was statistically significant (P < 0 01). During the initial course of six injections seven patients in the vaccine group and five in the placebo group developed wheeze and dyspnoea within 48 hours of an injection. These episodes were mild, but at the next weekly visit a second injection of...
