Present work demonstrates high speed friction stir welding (HSFSW) of light weight battery trays assembly in electric vehicle (EV). Despite solid-state and green nature FSW, it suffers from the relatively low speed. With help suitable tool design machine parameters, we successfully achieved defect-free welds at 4.0 4.5 m/min. Good quality are produced 3 mm thick AA6063-T6 extruded aluminium all...

We prospectively recorded all in-hospital complications of the first 3500 consecutive patients to undergo elective coronary angioplasty (PTCA) at Emory University Hospitals from July 14, 1980, to August 28, 1984, by three operators. PTCA was attempted in a total of 3933 lesions, with a primary success rate of 91%. Multiple-lesion PTCA was performed in 401 patients, and PTCA of saphenous vein gr...

Conditioned medium was collected from vascular smooth-muscle cells grown in culture to determine if these cells synthesize vasoactive substances. The medium caused a short-acting endothelium-independent constriction of rat aorta, followed by a prolonged, endothelium-dependent relaxation. This relaxation was mediated through the release of endothelium-derived relaxing factor (EDRF) as it was abo...

We have developed a significantly improved method for the electroporation of plasmid DNA into Staphylococcus aureus. The highest transformation efficiency achieved with this procedure was 4.0 x 10(8) transformants per microgram of plasmid pSK265 DNA. This represents a 530-fold improvement over the previously reported optimum efficiency of 7.5 x 10(5) transformants per microgram of plasmid DNA a...

In 2008, the top CO2 emitters were China, United States, and European Union. The rapid growing economy and the heavy reliance on coal in China give rise to the continued growth of CO2 emission, deterioration of anthropogenic climate change, and urgent need of new technologies. Carbon Capture and sequestration is one of the effective ways to provide reduction of CO2 emission and mitigation of po...

Cucurbit[7]uril selectively binds the epigenetic mark N(ε),N(ε),N(ε)-trimethyllysine (LysMe(3), K(CB[7]) = (1.8 ± 0.6)× 10(6) dm(3) mol(-1)) by 3500-fold over lysine ((5.3 ± 0.7) × 10(2) dm(3) mol(-1)) in aqueous solution, using ion-dipole interactions and the hydrophobic effect, rather than cation-π interactions, as in the "aromatic cages" of p-SO(3)-calix[4]arene hosts or chromodomain protein...

A pilot scale wastewater treatment plant was designed, constructed and operated on site to treat wastewater from a combined effluent drain. The activated sludge process (ASP) was used at three different hydraulic retention times (HRT) of 12, 10 and 8 hrs at an average MLSS concentration of 3500 mg/L. Under each HRT, the pilot plant was operated for a period of 10-12 weeks. Chemical oxygen deman...

An experimental investigation was conducted to study the combustion, performance, and emissions of an automotive spark ignition engine fuelled with ethanol (E100) methanol (M100). The tests were performed at same speed torque both fuels. It observed from results that In-cylinder peak pressure all speeds higher M100 than E100. cumulative heat release curve indicated start combustion advanced M10...
