The effect of river runoff over the northern Indian Ocean(NIO) especially over the Bay of Bengal(Bo B) has been studied using global Nucleus for European Modelling of the Ocean(NEMO). Two sensitivity experiments, with and without river runoff are conducted and the influence of river runoff on the Indian Ocean hydrography,stratification and circulation features are studied. It is found that due to river runoff surface salinity over the northern Bo B decreases by more than 5 and the East India Coastal Current strengthens by 2 cm/s during post monsoon season. The fresh river water reaches up to 15°N in the Bo B and is the main cause for low salinity *** surface temperature in the northwestern Bo B increases by more than 0.2℃ due to the river runoff in summer monsoon while surface cooling upto 0.2℃ is seen in north-west part of Bo B in winter season. The seasonal mixed layer depth in the region is found to be dependent on river runoff. The effect of vertical shear and Brunt Vaisala frequency on stratification is also examined. The ocean water becomes highly stratified up to 3 035 m due to the river runoff. It is found that the energy required for mixing is high in the northern and coastal Bo B.

A new approach to model viscosity in the conservation of momentum equations is presented and discussed. Coefficient of viscosity is modeled in such a way that it reaches asymptotically to infinity at the solid boundary but still yields a finite value for the shear stress at the solid wall. Basic objective of this research is to show that certain combinations of higher order normal velocity gradients become zero at the solid boundary. Malled solutions for the Couette flow and Poiseuille flow between two parallel plates are obtained by modeling the coefficient of viscosity in a novel way. Also, viscous drag computed by our model is expected to yield higher values than the values predicted by the existing models, which matches closely to the experimental data.

BackgroundCalcific aortic stenosis （AS） is an active process sharing similarities with atherosclerosis and chronic inflammation. The pathophysiology of AS is notable for three cardinal components： inflammation, fibrosis and calcification. Monocytes play a role in each of these processes. The role of circulating monocytes in AS is not clear. The aim of the present study was to study an association between cir-culating apoptotic and non apoptotic CD14＋ monocytes and AS *** assessed the number of CD14＋ monocytes and apoptotic monocytes in 54 patients with significant AS （aortic valve area 0.74 ± 0.27 cm2） and compared them to 33 patients with similar risk factors and no valvular disease. The level of CD14＋ monocytes and apoptotic monocytes was assessed by flow *** was no difference in the risk factor profile and known coronary or peripheral vascular diseases between patients with AS and ***-tients with AS exhibited increased numbers of CD14＋ monocytes as compared to controls （9.9% ± 4.9%vs. 7.7% ± 3.9%,P= 0.03）. CD14＋ monocyte number was related to age and the presence and severity of AS. In patients with AS, both CD14＋ monocytes and apoptotic mono-cytes were inversely related to aortic valve *** with significant AS have increased number of circulating CD14＋ monocytes and there is an inverse correlation between monocyte count and aortic valve area. These findings may suggest that inflammation is operative not only in early valve injury phase, but also at later developed stages such as calcification when AS is severe.

Initially developed to predict stroke probability in patientswith atrial fibrillation （AF）,t1~1 CHADS2 and CHA2DS2VASCscores are used to predict different outcomes in cardiac pa-tients in both acute and chronic conditions. Thescores were also demonstrated to correlate with mortal-ity. AF also has been associated with mortality indifferent groups of patients, including elderly.
