A specially designed circular towing tan~ was developed at the Northeast Fisheries Center (NEFC) for calibrating plankton-net flowmeters . ashore in order to provide more accurate volume estimates and to save valuable shipboard time. Results of a cross-calibration experiment with a flume in use at the Massachusetts Institute of Technology (MIT) demonstrated that calibration factors produced by ...

Lithium (Li), a glycogen synthase kinase-3β (GSK-3β) inhibitor, has used to attenuate thecannabinoid-induced dependence/withdrawal signs, but molecular mechanisms related to this areunclear. Recent studies indicate the involvement of upstream extracellular signal kinase1/2 (ERK1/2)and downstream GSK-3β pathways in the development of cannabinoid-induced dependence. Thisis mediated through cannab...

V porovnaní so sekvenčnými výpočtami sú výpočty využívajúce paralelizmus výrazne zložitejšie. Z teoretického pohl’adu je vel’mi prirodzeným modelom paralelných výpočtov model PRAM, ktorý je analógiou modelu RAM často používaného v teórii zložitosti. Z praktického pohl’adu je však zaručenie úplnej synchronizácie a uniformného prístupu k zdiel’anej pamäti, garantovaných modelom PRAM, značne probl...

Wireless intelligent network (WIN) is a network in the mobile environment that supports the use of intelligent network capabilities which is mainly made up of a service control point (SCP) and some mobile switching centers (MSCs). When there are too more incoming services to SCP and MSCs in the WIN simultaneously than they can handle will cause the SCP or MSCs overload and degrades the performa...

The effects of seagrass bed geometry on wave attenuation and suspended sediment transport were investigated using a modified Nearshore Community Model (NearCoM). The model was enhanced to account for cohesive sediment erosion and deposition, sediment transport, combined wave and current shear stresses, and seagrass effects on drag. Expressions for seagrass drag as a function of seagrass shoot d...

We prove that for any constant k and any < 1, there exist bimatrix win-lose games for which every -WSNE requires supports of cardinality greater than k. To do this, we provide a graphtheoretic characterization of win-lose games that possess -WSNE with constant cardinality supports. We then apply a result in additive number theory of Haight [8] to construct win-lose games that do not satisfy the...
