Heat transfer phenomena of flat plate solar collector filled with different nanofluids has been investigated numerically. Galerkin’s Finite Element Method is used to solve the problem. Heat transfer rate, average bulk temperature, average sub-domain velocity, outlet temperature, thermal efficiency, mean entropy generation and Bejan number has been investigated by varying the solid nanoparticle ...
Commercially available lipid-based transfection reagents are widely used to deliver DNA to cells. However, these lipid-based transfection reagents show poor gene transfer efficiency in primary cells. Here, we demonstrate a simple method to improve gene transfer efficiency in primary fibroblasts and hepatoblasts using a combination of lipid-based transfection reagents. Our data show that combine...
Förster resonant energy transfer can improve the spectral breadth, absorption and energy conversion efficiency of dye sensitized solar cells. In this design, unattached relay dyes absorb the high energy photons and transfer the excitation to sensitizing dye molecules by Förster resonant energy transfer. We use an analytic theory to calculate the excitation transfer efficiency from the relay dye...
Electronic devices usually operate in a variable loading condition and the power transfer efficiency of accompanying wireless (WPT) method should be optimizable to load. In this paper, reconfigurable WPT technique is introduced maximize weakly coupled, load application. A series-series two-coil network with resonators at frequency 150 kHz presented and, under condition, shunt capacitor element ...
INTRODUCTION During pregnancy, immunoglobulin G (IgG) is transferred from the mother to the fetus, providing protection from disease in early infancy. Plasmodium falciparum infections may reduce maternofetal antibody transfer efficiency, but mechanisms remain unclear. METHODS Mother-cord paired serum samples collected at delivery from Papua New Guinea (PNG) and the Thailand-Myanmar Border Are...
Carbonyl carotenoids are important constituents of the antenna complexes of marine organisms. These carotenoids possess an excited state with a charge-transfer character (intramolecular charge transfer state, ICT), but many details of the carotenoid to chlorophyll energy transfer mechanisms are as yet poorly understood. Here, we employ femtosecond transient absorption spectroscopy to study ener...
Conference organization and participation becomes subject of process optimization to increase the efficiency of knowledge transfer and the scientific exploitation of emerging communities of interest. Process optimization starts with a process model to analyse the planning aspects, the information flow, the coordination efficiency, and finally the efficiency of the knowledge transfer. Considerin...
In this study we compare the efficiency of different blotting techniques, including semi-dry, tank transfer, and fast blotting systems on proteins across a wide range of molecular weights with particular emphasis on large proteins (≥200 kD). We also conducted experiments transferring high molecular weight proteins that are difficult to transfect using conventional methods. The results demonstra...
