Slip Effects on MHD Peristaltic Motion with Heat and Mass Transfer

Abstract: This investigation looks at the magnetohydrodynamic peristaltic flow of a viscous fluid occupying a porous space. Channel walls are compliant and the velocity, temperature and concentration slip effects are taken into account. Heat and mass transfer effects are present. Long wavelength approach is utilized in the mathematical description of arising problem. Expressions for stream function, temperature, concentration field and heat transfer coefficient are prepared. The role of key parameters is carefully analyzed. The velocity, temperature and absolute concentration distributions are found to decrease upon increasing the strength of magnetic field. This study reduces to the investigation of Kothandapani and Srinivas (Appl Math Comput 213:197–208, 2009) by neglecting the slip effects.

Discovery of selective inhibitors for cyclic AMP response element-binding protein: a combined ligand and structure-based resources pipeline.

Abstract: Bromodomains are epigenetic readers of acetyl-lysine involved in chromatin remodeling and transcriptional regulations. Over the past few years, extensive research has been carried out to discover small-molecule inhibitors against bromodomains to treat various diseases. Cyclic AMP response element-binding protein (CREBBP) bromodomain has emerged as a hot target for cancer therapy. This study aims at discovering new inhibitors against CREBBP bromodomain using ligand-based molecular docking. A library of 2168 lead-like compounds were docked into the Kac binding site of CREBBP bromodomain. On the basis of the energy score and interaction analysis, six compounds were selected. In order to validate the stability of these six protein-ligand complexes 20 ns molecular dynamics simulations and principal component analyses were carried out. Based on the different analyses these six compounds may provide valuable information for developing CREBBP selective inhibitors.

Analysis of sorption efficiency of activated carbon for removal of anthracene and pyrene for wastewater treatment

Abstract: The potential carcinogenicity and mutagenicity has placed polycyclic aromatic hydrocarbons (PAHs) on top priority calling for immediate management strategies. The present study draws its rationale that industries should opt for sustainable and economically viable solutions. The powdered activated carbon (PAC) is applied as adsorbent for removal of anthracene and pyrene under ambient conditions. Aliquot of batch run on GC–MS demonstrated progressively increasing percentage removal of anthracene and pyrene with increase in time. Further, pyrene shows a slower but regular increase in adsorption with distinct equilibrium at 100 min. However, anthracene depicts simultaneous adsorption–desorption pattern with multiple equilibriums. This suggests that pyrene is more stable due to its higher molecular weight and boiling point resisting its diffusion into adsorbent. The maximum removal of >99% is achieved after contact of 4 h between adsorbate and adsorbent. The fitness of pseudo-first-order kinetics sugge...

Computation of Power Extraction From Photovoltaic Arrays Under Various Fault Conditions

Abstract: Photovoltaic (PV) faults such as partial shading, bypass-diode defects, degradation of PV modules, and wiring issues greatly affect the power output and cause various peaks in P-V curves of a PV system. Although, commonly used Total-Cross-Tied (TCT) scheme in PV arrays is considered instrumental for reducing power losses there lies a great scope to evaluate power extraction through reconfiguration of modules with different PV materials. This paper presents detailed investigation of power extraction using number placement reconfiguration method under numerous faults. PV power extraction is carried out and compared with three different interconnections of PV modules, including series-parallel (SP), bridge-link (BL) and TCT. In order to conduct a thorough investigation and better evaluate the performance of PV arrays, we have studied reconfiguration of PV modules with polycrystalline and copper indium gallium selenide (CIGS) PV technologies. In addition, this paper contains detailed quantification of the impact of the studied PV faults on power grid. The results obtained in MATLAB/Simulink demonstrate that CIGS PV technology performs better than polycrystalline in terms of power output during different faulty conditions. It becomes evident from the presented results that optimal reconfiguration of PV arrays can increase the power extraction from PV system with reduced number of P-V peaks. Hence, leading to improved performance of the PV system.
