A comparative study of five cases of blocking action in the upper westerlies is presented with the two-fold objective of obtaining a more complete description of this phenomenon and of attempting an explanation of its initiation, development and dissipation in terms of parameters derived from an hydraulic analogue. The effect of European blocking upon the zonal and meridional circulation indice...

In an attempt to produce allonatibodies to cytotoxic T-cell receptors, hyperimmune anti-lymphocyte antisera have been raised in mice of various strain combinations, and have been tested for their ability to block allogeneic cell-mediated lymphocytotoxicity (CML) in the absence of complement at the T killer cell level. Most of the sera failed to show any significant and reproducible inhibitory e...

Distribution centers are under increasing pressure to adopt material handling systems that offer greater flexibility to improve cycle time and throughput capacity in the transfer of unit loads in their high density storage areas. Autonomous Vehicles-based Storage and Retrieval Systems (AVS/RS), have been shown to hold significant promise in this context. In these systems, loads are transferred ...

OVSF (Orthogonal Variable Spreading Factor) codes are used in WCDMA uplink and downlink transmission for multirate traffic. The orthogonal property of these codes leads to code blocking and new call blocking. Two code (or slot) sharing assignment schemes are proposed to reduce the effect of code blocking using OVSF and NOVSF (non blocking OVSF) codes. The schemes favor the real time calls as th...

Coalbed methane development primarily relies on hydraulic fracturing and drainage gas extraction processes. The intrusion of external fluids long-term contribute to the water blocking effect, which becomes one crucial factors affecting production capacity. In this study, coal reservoir a certain coalbed in Hancheng, Shaanxi Province, was selected as research object. experimental method employed...

We propose an admission control policy for wireless multimedia networks that is based on the well known threshold-based guard channel method. The new scheme deals with two different types of traffic classes; namely: voice and data. We assume two different thresholds, one for each traffic class. In addition, we propose to buffer the handoff data calls if no free channels are available rather tha...

introduction: previous studies have shown that cannabinoidergic system is involved in anxiety. however, there are controversial reports in the experimental studies. the aim of this study is to evaluate the effect of pharmacological stimulation or blocking of cb1 receptors and inhibition of endocannabinoid degradation in anxiety like behavior in elevated plus-maze (epm) test in rat. the epm is o...
