A kind of microcapsule sustained-release–type hydration heat inhibitor (MSR) was prepared. The effect MSR on semi-adiabatic temperature rise, setting time, and strength low-heat Portland cement investigated. Microcalorimetry, XRD, SEM, TG-DSC were used to investigate the mechanism cement. results showed that had good regulating When dosage 0.3%, release rate decreased by 10% peak 52%. 3D compre...

Now a day’s technology enhancement is at a blistering pace. Merely VLSI has a meteoric rise due to the adoption of new techniques. Static CMOS had a limitation of deploying constant power supply. Less power dissipation is an essential attribute for any optimized design. Varying the power supply is the very thing for preventing the power dissipation. An adiabatic logic is a new technique to redu...

a r t i c l e i n f o Keywords: paleoaltimetry geodynamics paleoclimate stable isotopes Andes plateau Recent elevation reconstructions of the Andean Plateau suggest a rapid 2.5 ± 1.0 km rise of the central Andes between ~10 and 6 Ma. This rapid rise has been attributed to a catastrophic removal of a dense lithospheric mantle root beneath the Andes. However, these findings are based on the assum...

introduction : this in vitro study was designed to measure and compare the amount of temperature rise in the pulp chamber of the teeth exposed to different light curing units (lcu), which are being used for curing composite restorations. methods: the study was performed in two settings; first, an in vitro and second was mimicking an in vivo situation. in the first setup of the study, three grou...

Based on ideas of off-diagonal long range order and two-fluid model, we demonstrate that adiabatic phases for a slow motion of a vortex in a superconductor film give rise naturally to the Magnus force at finite temperatures.

Advanced high strength steels (AHSS) have recently attracted great attention because of their superior mechanical properties. A modern group of these steels, known as twinning induced plasticity (TWIP) steels, shows a unique combination of strength and ductility even at high rates of strain. In order to examine the functionality of such steels in dynamic loading conditions, their mechanical beh...

Abstract The current study presents the effects of strain and temperature on mechanical response microstructure evolution in AA7075-T651 at high rates. Compression tests have been performed room (RT), 200, 300 400 °C using a Split-Hopkinson pressure bar (SHPB) setup with rates ranging between 1400 5300 s −1 . For deformation RT, flow stress increases increase rate. Whereas elevated temperatures...

the objective of this paper is to develop an artificial neural network (ann) model which can beused to predict temperature rise due to climate change in regional scale. in the present work data recorded overyears 1985-2008 have been used at training and testing steps for ann model. the multilayer perceptron(mlp) network architecture is used for this purpose. three applied optimization methods a...
