The present study was conducted on the gills structure and the gill surface area of 40 individuals of the Blue swimming crabs, Portunus pelagicus, and 40 Chinese mitten crabs, Eriocheir sinensis, specimens of the species were collected from the different regions of Shatt Al- Arab and North-west Arabian gulf. Both species were having eight phyllobranchiatesas of the same structure but different in length and surface area. The second gill in P. pelagicus shows major difference in shape from the other gills with missing platelets from one side of the filament. The results showed there were positi

Abstract:
The uptake of amino acids by the non-gill epithelia of the mantle cavity of Mytilus edulis L. was studied and compared with uptake by the gills. Amino acid entry rates and the subsequent distribution of amino acids to the other tissues of the animals were studied using high-performance liquid chromatography and radiochemical techniques. Uptake via the non-gill epithelia lining the mantle cavity was separated from uptake via the gill by employing a preparation in which the gills were surgically removed. Amino acid uptake by such animals was compared with that of suitably sham-operated controls.

Blood flow and water flow are separated only by the epithelium with a ‘countercurrent’ gas exchange between the two.

Large body surface areas per unit mass and correlated drag forces could account for ‘transient’ modes of swimming in small fish. Some species show large mass-specific development of gill area and, in this respect, are thought to be paedomorphic. Gill development in miniat

At the locations of these gill cells, the buoyancy forces are eliminated. When placed appropriately, these gill cells are very cost effective in minimizing the differential deflection of the loaded structure. So the optimal layout of the gill cells is

Abstract:
Heat transfer and film cooling distributions have been acquired downstream from the exit of a nozzle guide vane gill slot (or cutback). Additionally, heat transfer and pressure drop data have been experimentally determined for a pin fin array within the gill slot geometry. Generally, average row pin fin heat transfer levels for the converging channel correlate quite well with archival literature. However, no generalized flow friction factor correlation was found to predict the pressure drop within the array. Experimental data for the region downstream from the gill slot have been acquired over

Abstract:
Climate warming is expected to degrade permafrost in many regions of the world. Degradation of permafrost has the potential to affect soil thermal, hydrological, and vegetation regimes. Projections of long-term effects of climate warming on high-latitude ecosystems require a coupled representation of soil thermal state and hydrological dynamics. Such a coupled framework was developed to explicitly simulate the soil moisture effects of soil thermal conductivity and heat capacity and its effects on hydrological response. In the coupled framework, the Geophysical Institute Permafrost Laboratory (
