The concept of urban sprawl spans multiple dimensions indicating how built-up land cover adds up throughout exurban landscapes. These different require a re-examination definitions and their driving forces because certain policies were formulated from the proposition informed knowledge have implicitly gratified into adjoining peripheries. This article aimed to offer an alternative perspective o...

In this study, we aim to evaluate the shape memory effect of a Poly (Caprolactone) (PCL) (40%) and Styrene-Butadiene-Styrene (SBS) (60%) blend. Shape cycle tests are performed at different temperatures detect best recovery rate. Under appropriate temperature, blend recovers substantially its original shape. To study rate evolution, multi realized with controlled temperature. The results indicat...

Washed cells of strain H18, a newly isolated ruminal selenomonad, decarboxylated succinate 25-fold faster than Selenomonas ruminantium HD4 (130 versus 5 nmol min-1 mg of protein-1, respectively). Batch cultures of strain H18 which were fermenting glucose did not utilize succinate, and glucose-limited continuous cultures were only able to decarboxylate significant amounts of succinate at slow (l...

The underlying theory of a new actuator concept based on hydrogel core flexible matrix composites (H-FMC) is presented. The key principle that underlines the H-FMC actuator operation is that the three-dimensional swelling of a hydrogel is partially constrained in order to improve the amount of useful work done. The partial constraint is applied to the hydrogel by a flexible matrix composite (FM...

impact pile driving is a multi-component problem which is associated to multi-directional ground vibrations. at first, vibration is transferred from the hammer to the pile and then to the common interface of pile and soil. this is then transferred to the environment and has great impact on the adjacent structures, causing disturbance to residents and also damage to the buildings. it is of high ...

in this study at first , an azo dye, 2,7- naphthalenediol, 2-[(4-bromophenyl)azo (bpand) as a ligand has been synthesized by addition of p-bromoaniline to the modified montomorillonite k10 clay. this ligand was characterized using 1h-nmr, uv-vis and ir spectroscopies. subsequently, its interaction with calf thymus deoxyribonucleicacid ,ct-dna was investigated in 5 mm phosphate buffer solution, ...

Abstract Nowadays, the fabrication of microelectromechanical systems has given rise to several studies whose main purpose is obtain greater benefit micro-nano scales, putting special interest in improvement design such devices. One applications harvesting energy due electrokinetic phenomena, more specifically, streaming potential. Nonetheless, there a lack theoretical encompassing coupled asymm...
