Israel and the Palestinian Authority share the southern Mediterranean coastal aquifer. Long-term overexploitation in the Gaza Strip has resulted in a decreasing water table, accompanied by the degradation of its water quality. Due to high levels of salinity and nitrate and boron pollution, most of the ground water is inadequate for both domestic and agricultural consumption. The rapid rate of p...

[1] Temporary storage of solutes in streams is often controlled by flow-induced uptake in hyporheic zones. This phenomenon accounts for the tails that are generally observed following the passage of a solute pulse, and such exchange is particularly important for the transport of reactive substances that can be subject to various biogeochemical processes in the subsurface. Advective pumping, ind...

We explore an embryonic heart model that couples electrophysiology and muscle-force generation to flow induced using a 2D fluid-structure interaction framework based on the immersed boundary method. The propagation of action potentials are coupled to muscular contraction and hence the overall pumping dynamics. In comparison to previous models, the electro-dynamical model does not use prescribed...

We present a pumping lemma for the class of collapsible pushdown graphs of level 2. This pumping lemma even applies to the ε-contractions of level 2 collapsible pushdown graphs. Our pumping lemma also improves the bounds of Hayashi’s pumping lemma for indexed languages. 1998 ACM Subject Classification F.1.1 Models of Computation

The Super SOR is a third-generation VUV and soft Xray light source that is being designed at the University of Tokyo. Eight insertion devices (ID) including a 27-m long undulator will be installed in the ring. Since the ring has a very narrow acceptance for beam loss by collision with residual gases, the vacuum system is required to achieve operation pressure of 10 Pa range in order to guarante...

Oxygen consumption of the Red Sea coral reef sponge Negombata magnifica was measured using both incubation and steady-state methods. The latter method was found to be the more reliable because sponge activity remained stable over time. Oxygen consumption rate was measured during three levels of sponge activity: full activity, reduced activity and basal activity (starved). It was found that the ...

We study nonadiabatic two-parameter charge and spin pumping through a single-level quantum dot with Coulomb interaction. For the limit of weak tunnel coupling and in the regime of pumping frequencies up to the tunneling rates, Omega less, similar Gamma/variant Planck's over 2pi, we perform an exact resummation of contributions of all orders in the pumping frequency. As striking nonadiabatic sig...

INTRODUCTION Intra-aortic balloon pumping is used in elective percutaneous coronary intervention for increasing coronary blood flow. However, intra-aortic balloon pumping may decrease visceral blood flow and cause mesenteric ischemia by visceral artery obstruction. CASE PRESENTATION We report the case of a 79-year-old Asian man in whom elective percutaneous coronary intervention was performed...

Introduction It is unclear whether the use of linear peristaltic infusion pumps with different propulsion mechanisms can affect the quality of red blood cells (RBCs) transfusion. We hypothesized that the mechanism of liquid propulsion, infusion rate, complete or incomplete compression of the infusion sets segment and type of pumping segment composition materials are variables that can influence...
