due to the fact that many application processes take place at different temperature, better examining and understanding of swelling properties as a function of temperature is essential for such application. the temperature effect on the swelling properties of commercial polyacrylic acid (paa) hydrogel beads was investigated as a function of time and temperature. gel bead size, swelling equilibr...

Current-induced magnetic excitations in Co/Cu/Co bilayer nanopillars s,50 nm in diameterd have been studied experimentally at low temperatures for large applied fields perpendicular to the layers. At sufficiently high current densities excitations, which lead to a decrease in differential resistance, are observed for both current polarities. Such bipolar excitations are not expected in a single...

The activation of the ethene tetramerisation catalyst system based upon [CrCl3(THF)3] and N( Pr)(PPh2)2 has been investigated in situ via the reaction of [CrCl3{PPh2N(R)PPh2}(THF)] 1a (R = Pr) with excess AlMe3 in toluene. The Cr K-edge XAFS spectrum of the solution freeze quenched after 1 min reaction time indicated monomethylation of the metal with the resultant product being [CrClMe(ClAlCl3)...

A multimedia feature for unsteady magnetic hydrodynamic (MHD) flow of two-dimensional mixed convection flow of an incompressible viscoelastic fluid over a vertical stretching sheet with viscous dissipation was studied. Similar transformation and an implicit finite-difference method were used to analyze the present problem. The numerical solutions of the flow velocity distributions, temperature ...

The direct numerical simulation (DNS) of heat transfer in a fully developed turbulent pipe flow with for various Prandtle numbers are performed to obtain statistical quantities such as turbulent heat flux, and temperature variance. Main emphasis is placed on Prandtl number effects on turbulent heat transfer in pipe flow. Probability density functions and joint probability density functions of v...

in this paper, the temperature dependence of some characteristics of cylindrical gate-all-around si nanowire field effect transistor (gaa-si-nwfet) is investigated to representing the temperature nano-sensor structures and improving their performance. firstly, we calculate the temperature sensitivity of drain-source current versus the gate-source voltage of gaa-si-nwfet to propose the temperatu...

Bao, Jialin, Kaori Sato, Min Li, Youhe Gao, Ruhul Abid, William Aird, Michael Simons, and Mark J. Post. PR-39 and PR-11 peptides inhibit ischemia-reperfusion injury by blocking proteasome-mediated IkBa degradation. Am J Physiol Heart Circ Physiol 281: H2612–H2618, 2001.— PR-39 inhibits proteasome-mediated IkBa degradation and might protect against ischemia-reperfusion injury. We studied PR-39, ...
