Effects of Thermophoresis on Unsteady MHD Free Convective Heat and Mass Transfer along an Inclined Porous Plate with Heat Generation in Presence of Magnetic Field

An analysis of Thermophoresis effect on unsteady magneto-hydrodynamic free convection flow over an inclined porous plate with time dependent suction in presence of magnetic field with heat generation has been considered by employing Nachtsheim-Swigert shooting iteration technique along with sixth order Runge-Kutta integration scheme. Resulting non-dimensional velocity, temperature and concentration profiles are then presented graphically for different values of the parameters entering into the problem. Finally, the effects of the pertinent parameters on the skin-friction coefficient, the rate of heat transfer (Nusselt number) and wall deposition flux (Stanton number), which are of physical interest, are exhibited in tabular form.

Vulnerability of inland and coastal aquaculture to climate change: Evidence from a developing country

Developing countries,which contribute 90%of global aquaculture production,are considered global climate risk hotspots.However,no study focuses on measuring district-or sub-national-level aquaculture vulnerability to climatic hazards or disasters.This study has measured the level of aquaculture vulnerability to climate variability and change in all 64 districts of Bangladesh using a composite vulnerability index approach(using 19 climatic,environmental and socio-economic indicators)and geographical information system(GIS).The results reveal that aquaculture in 12 districts namely Satkhira,Mymensingh,Panchagarh,Lalmonirhat,Nilphamari,Thakurgaon,Sunamganj,Dinajpur,Kurigram,Noakhali,Lakshmipur,and Cox's Bazar have very high vulnerability(in order of highest to lowest vulnerability),which are explained by their higher level of exposure,moderate level of sensitivity,and lower to moderate level of adaptive capacity.Among these,8 districts belong to inland and 4 districts to coastal regions of the country.Three districts,namely Dhaka,Chittagong,and Bandarban,have the lowest level of aquaculture vulnerability(in order of lowest to highest vulnerability)mainly because of very high adaptive capacity and moderate or low level of sensitivity and exposure.This study will punctuate the vulnerability of inland aquaculture and develop and prioritize actions to reduce the climatic impacts.
