Abstract: Transverse aortic constriction (TAC)-induced pressure overload (PO) causes adverse cardiac remodeling and dysfunction that progresses to heart failure (HF). The purpose of this study was to determine whether the potent antioxidant, resveratrol, significantly attenuates PO-induced HF in wild-type mice. Male C57BL6 mice were subjected to either sham or TAC surgery. One group of TAC mic…
Manipulation of microscopic objects, especially biological objects and microelectromechanical systems (MEMS) components, has become an important area of robotics research over the past several years. Automation is necessary as it is challenging to manually control the microobjects due to the scaling effect of the surface forces, stochastic motion of objects in fluid media, and uncertainty assoc…
Background: Extensive or recurrent tinea versicolor (TV) can be treated with systemic antifungal therapies, but no dosing regimens have been approved for this indication. Objective: To provide evidence-based recommendations for dosing regimens. Methods: A systematic literature searchwas performed to identify trials reportingmycologic cure. All trials were included and assessed for quality…
This chapter presents the manufacturing of high quality miniature spur gears of brass by Wire Electric Discharge Machining (WEDM). Effects of four WEDM parameters i.e. voltage, pulse-on time, pulse-off time and wire feed rate on five responses namely profile error, pitch error, average roughness, maximum roughness and material removal rate are studied. The experimental research was accomplished…
Abstract. SBA-15 containing various amount (10–50 wt.%) of highly dispersed ZrO2 is prepared using urea hydrolysis method. The sulfated zirconia (ZrO2) in SBA-15 catalysts were prepared using these materials. The materials were characterized by XRD, BET surface area, TEM, TGA, acidity measurements using in situ IR pyridine adsorption, sulfate content and catalytic activities were studied …
Abstract. Raman scattering is used to study the temperature-driven structural transformations of bundled single-walled carbon nanotubes (SWCNTs) observed in HiPCO and ARC synthesis by electron microscopy, i.e., tube–tube coalescence 1300–1400 oC, coalesced tubes to multi-walled tubes (MWCNT) at 1600–1800 oC and finally (only ARC tubes) MWCNT to graphitic nanoribbons (GNRs) at 18…
Abstract. The present study deals with the application of bottom ash, a power plant waste, and deoiled soya, an agricultural waste, for the adsorptive removal of carmoisine A dye from its aqueous solutions. This paper incorporates a comparative study of the adsorption characteristics of the dye on these effective adsorbents along with effects of time, temperature, concentration, and pH. Ana…
Abstract. Photodegradation of an organic dye was studied experimentally using novel polymer–titania microcomposites. These microcomposites were prepared from titanium dioxide (TiO2) nanoparticles embedded within cross-linked, thermally-responsive microgels of poly(N-isopropylacrylamide) and contained interpenetrating linear chains of poly(acrylic acid) that functionalize the nanoparticles…
The article describes the systematic studies on the lubrication properties of biodiesel, low sulfur diesel fuel, and their blends. Biodiesel from nonedible oils (e.g., Jatropha curcas, Pongamia glabra, Madhuca indica, and Salvadora oleoides) were prepared by base-catalyzed transesterification using methanol; high-speed diesel (HSD) used was from Panipat refinery. The lubricity evaluation of bio…
Removal of toxic substances from wastewaters using low-cost alternatives to activated carbon is an important area in environmental sciences. Efforts have been made to convert a fertilizer waste and a steel industry waste into low-cost potential adsorbents. The developed products have been used for the removal of 2-aminophenol from aqueous solutions and wastewaters. Studies were conducted to …
