A theoretical method for calculating the compressive arch capacity of RC beams against progressive collapse

Reza Abbasnia、Foad Mohajeri Nav2015-07-15Structural Concrete

Compressive arch action is one of the main resistance mechanisms against progressive collapse in reinforced concrete (RC) buildings. Hence, many studies have investigated the development of arching action in RC beams and frames but less attention has been paid to calculating the corresponding enhancement in structural…

Zoraida Megías、Cecilia Martínez、S. Manzano 等 8 位作者2015-07-15PLoS ONE

We have studied the effect of individual shrink wrapping (ISW) on the postharvest performance of refrigerated fruit from two zucchini cultivars that differ in their sensitivity to cold storage: Sinatra (more sensitive) and Natura (more tolerant). The fruit was individually shrink wrapped before storing at 4°C for 0, 7…

Force–displacement response of in‐plane‐loaded URM walls with a dominating flexural mode

Sarah Petry、Katrin Beyer2015-07-15Earthquake Engineering & Structural Dynamics

Summary This article presents a new mechanical model for the non‐linear force–displacement response of unreinforced masonry (URM) walls developing a flexural rocking mode including their displacement capacity. The model is based on the plane‐section hypothesis and a constitutive law for the masonry with zero tensile s…

Tomohiro Shimada、Natsumi Saito、Michihisa Maeda 等 5 位作者2015-07-15Microbial Genomics

Leucine-responsive regulatory protein (Lrp) is a transcriptional regulator for the genes involved in transport, biosynthesis and catabolism of amino acids in Escherichia coli. In order to identify the whole set of genes under the direct control of Lrp, we performed Genomic SELEX screening and identified a total of 314…

Adding high time resolution to charge-state-specific ion energy measurements for pulsed copper vacuum arc plasmas

Kōichi Tanaka、Liang Han、Xue Zhou 等 4 位作者2015-07-15Plasma Sources Science and Technology

Charge-state-resolved ion energy–time distributions of pulsed Cu arc plasma were obtained by using direct (time-dependent) acquisition of the ion detection signal from a commercial ion mass-per-charge and energy-per-charge analyzer. We find a shift of energies of Cu 2+ , Cu 3+ and Cu 4+ ions to lower values during the…

Manmohan L. Satnami、Sandeep K. Vaishanav、Rekha Nagwanshi 等 4 位作者2015-07-15Journal of Dispersion Science and Technology

Heavy metal ions such as Hg and Pb are hazardous due to very high toxicity, mobility, and ability to accumulate through the food chain or atmosphere in the environment system. Therefore, ultrasensitive determination of mercury and lead is important to provide an evaluation index of ions in aqueous environment. This pa…

Waveguide‐Plasmon Polariton Enhanced Photochemistry

Charlene Ng、Svetlana Dligatch、H. Amekura 等 5 位作者2015-07-15Advanced Optical Materials

One key process in plasmon‐enhanced photocatalysis is the transfer of hot charge–carriers from metal nanostructures into photocatalytically active materials. This process is secondary to the initial step of light absorption by the metal nanostructures. Light absorption in these structures can be controlled by designin…

Geometric interpretations for resonances of plasmonic nanoparticles

Wei Liu、Rupert F. Oulton、Yuri S. Kivshar2015-07-15Scientific Reports

The field of plasmonics can be roughly categorized into two branches: surface plasmon polaritons (SPPs) propagating in waveguides and localized surface plasmons (LSPs) supported by scattering particles. Investigations along these two directions usually employ different approaches, resulting in more or less a dogma tha…
