Abstract:

This work numerically investigated the steady state fluid flow and heat transfer behaviors associated with a sintered porous channel that contains periodically spaced heated blocks. Some typical cases are experimentally examined in this study. The relevant varied parameters were the average bead diameter (d), the relative block height (h∕H), the relative block width (w∕H), the relative block spacing (s∕H), and the Reynolds number (Re). The numerical results revealed a lack of global recirculation in regions between the blocks, where the forced convective heat transfer was low, but the heat in

Two series of load-bearing horizontal-hole interlocking hollow concrete blocks, referred to as H-shaped series and cross-shaped series, were developed, including three geometric types: type BH-290 (H-shaped), type BH-240 (H-shaped), and type BC-240 (cross-shaped). The research presented in this article investigated the compressive behavior of the proposed load-bearing horizontal-hole interlocking hollow concrete blocks and aimed at analyzing the influence of geometric parameters on the block capacity. First, compressive tests of the horizontal-hole interlocking hollow concrete blocks were carr

Abstract:

Factors affecting diversity and distribution of globally threatened birds were studied by dividing Chitwan National Park (CNP) into five study blocks consisting of 17 birding routes. CNP provides major habitats for the feeding and breeding of a large number of migratory birds from many parts of the globe and also plays a vital role in the conservation of threatened species. We recorded a total of 437 individuals of globally threatened birds belonging to 19 species of nine families and eight orders. There was considerable variation (F=2.94, df=44.43, p=0.05) in species diversity of threatened b

AbstractHere we report a nomenclature and classification for the astrophyllite-supergroup minerals. The HOH block is the main structural unit in all astrophyllite-supergroup structures; it consists of three H–O–H sheets where the T4O12 astrophyllite ribbons occur in the H sheets. In each structure, HOH blocks alternate with I (Intermediate) blocks along [001].

Abstract:

The incidence of hip fractures has continued to increase as life expectancy increases. Hip fracture is one of the leading causes of increased morbidity and mortality in the geriatric population. Early surgical treatment (<48 h) is often recommended to reduce morbidity/mortality. In addition, adequate pain management is crucial to optimize functional recovery and early mobilization. Pain management often consists of multimodal therapy which includes non-opioids, opioids, and regional anesthesia techniques.

Flow around two-dimensional roughness elements in the form of rectangular blocks has been analyzed for reynolds number 0 ≤Re≤40 and blocks of aspect ratio 0.01 ≤W/h≤∞.

The size of the upstream separation zone weakly depends on the length of the block but decreases rapidly with an increase of the Reynolds number. In contrast, the length of the downstream separation zone increases almost linearly as Re increases. While this length depends weakly on the aspect ratio of the block, the velocity magnitude inside the separation

Methods Adult patients scheduled for foot and ankle surgery were randomized to receive combined sciatic-femoral nerve block with 225 mg of either 0.5% (n = 83), 0.75% (n = 87), or 1% (n = 86) ropivacaine, or with 500 mg of 2% mepivacaine (n = 84). A thigh tourniquet was used in all patients. Onset time, adequacy of surgical anesthesia, time to offset of nerve block, an

Background The main determinant of continuous peripheral nerve block effects--local anesthetic concentration and volume or simply total drug dose--remains unknown. Methods We compared two different concentrations and basal rates of ropivacaine--but at equivalent total doses--for continuous posterior lumbar plexus blocks after hip arthroplasty. Preoperatively, a psoas compartment perineural catheter was inserted. Postoperatively, patients were randomly assigned to receive perineural ropivacaine of either 0.1% (basal 12 ml/h, bolus 4 ml) or 0.4% (basal 3 ml/h, bolus 1 ml) for at least 48 h. Ther

Abstract:

The objective of this work is to propose a novel idea of transforming temporal redundancies present in videos. Initially, the frames are divided into sub-blocks. Then, the temporally redundant blocks are grouped together thus generating new frames with spatially redundant temporal data. The transformed frames are given to compression in the wavelet domain. This new approach greatly reduces the computational time. The reason is that the existing video codecs use block matching methods for motion estimation which is a time consuming process. The proposed method avoids the use of block matching m
