Research ArticleOpen accessIn the abstractSustainable Development through Waste Heat RecoveryP. S. Bundela, Vivek ChawlaProblem statement: Waste Heat Recovery (WHR) steam Technology is a proven Technology pioneered by Japanese for cement plant and it is economically viable. Electrical Power can be generated by adopting the latest technology in this field. It used a medium to low temperature (120-350°C) Turbine technology (standard thermal power plants run on steam temp-500°C). Approach: It requires treat exchangers (Hx) … …American Journal of Environmental Sciences, Vol. 6, Issue 1 · 28 Feb 2010 · 7,401 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdsorption Study of Several Hydrophobic Organic Contaminants on an Aquifer MaterialBarbara Ruffino, Mariachiara ZanettiProblem statement: Aim of the present research was to determine coefficient of partition KD between soil and groundwater for five hydrophobic organic pollutants (benzene, chlorobenzene, trichloroethylene-TCE, perchloroethylene-PCE and toluene) in an Italian aquifer material characterized by a low organic carbon content (fOC = 0.00262) by means of laboratory batch tests. Initial aqueous concentrations (quite different among the five compounds) were … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 7,366 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Maturity Level in Laying Hen Manure by Chemical and Thermogravimetric AnalysisAlice Dall’Ara, Francesco Antolini, Laura Billi et al.This study aims at investigating maturity levels in manure from laying hens in order to encourage its agronomic re-utilization. In fact the use of unstable/insufficiently mature manure could potentially damage both soils and crops. Effective, easy to reproduce methods are needed in order to assess bio-stabilisation and maturity levels, particularly for biomass that has not undergone conventional composting. This study … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 6,540 accessesView PDFCite
Research ArticleOpen accessIn the abstractWhat is Xenohormesis?Joseph A. Baur, David A. SinclairPolyphenols such as resveratrol and quercetin, which are produced by stressed plants, activate sirtuin enzymes and extend the lifespan of fungi and animals, ostensibly by mimicking the beneficial effects of caloric restriction. This observation raises an interesting question: Why should foreign molecules that are non-nutritive and seemingly unrelated to any endogenous molecule modulate the same biochemical pathways that mediate the … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 10,386 accessesView PDFCite
Research ArticleOpen accessIn the abstractConservation of “Partial Vorticity” with Application on Hydraulic JumpsHarald NaeserIn two preceding works, the idea of partial conservation theorems was introduced and conservation equations for partial energy and partial angular momentum were established. A similar conservation theorem for partial vorticity of incompressible fluids is established here. The vorticity vector is divided into two elements (both denoted “partial vorticity”) and their conservation equations established separately. They show that, in addition … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 6,704 accessesView PDFCite
Research ArticleOpen accessIn the abstractSex Dimorphism in the Fgf21 Gene Expression in Liver and Adipose Tissues is Dependent on the Metabolic ConditionNadezhda Bazhan, Tatiana Jakovleva, Natalia Balyibina et al.Fibroblast growth factor-21 (FGF21) beneficially affects carbohydrate and lipid metabolism. Previously, a sex-specific activation of Fgf21 expression was observed in humans and animals with metabolic diseases. It is unknown whether the sex differences in the Fgf21 expression are manifested in response to the natural physiological situations of fasting and refeeding. The aim of this work was to determine liver, White … …OnLine Journal of Biological Sciences, Vol. 19, Issue 1 · 29 Jan 2019 · 8,153 accessesView PDFCite
Review ArticleOpen accessIn the abstractContinuous Flow Synthesis of Zeolite-A from Coal Fly Ash Utilizing Microwave Irradiation with Recycled Liquid StreamSalman Bukhari, Sohrab RohaniCoal Fly Ash (CFA) was converted to zeolite using continuous microwave reactors while minimizing the wastewater produced during the zeolitization process. At bench scale, a continuous flow tubular microwave reactor was used to explore the effect of microwave irradiation on the crystallinity of the product. The waste water was reused in consecutive runs and Inductively Coupled Plasma (ICP) analysis was … …American Journal of Environmental Sciences, Vol. 13, Issue 3 · 19 Jun 2017 · 7,237 accessesView PDFCite
Research ArticleOpen accessIn the abstractBinding Interaction between Bovine Serum Albumin and Chicoric Acid, a Food Functional ComponentHaifang Xiao, Quancai Sun, Xuebo Liu, Yuanda SongFuorescence, FTIR and UV-Vis absorption spectroscopy were used to explore the binding between chicoric acid and Bovine Serum Albumin (BSA). Binding characteristics at various levels of temperature have been calculated. The results indicated that chicoric acid statically quenched the intrinsic fluorescence of BSA. The binding constants (Ka) were 4.14×105 L mol-1 at 273K and 4.29×106 L mol-1 at 298 k. … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 3 · 19 Sep 2016 · 7,552 accessesView PDFCite
Research ArticleOpen accessIn the abstractOsmotic Tension, Plasticization and Viscoelastic response of amorphous Poly-Ether-Ether-Ketone (PEEK) equilibrated in humid environmentsAversa Raffaella, Apicella AntonioDynamic-Mechanical Analysis (DMA), Differential scanning Calorimetry (DSC) and water moisture sorption-desorption kinetics and equilibria have been parallely investigated to monitoring the environmental and thermal sensitivity of amorphous thermoplastic Poly-Ether-Ether-Ketone (PEEK). Morphological modification occurring in PEEK during the calorimetric and thermo-mechanical characterizations and the hygrothermal stability are presented. An interpretation based on the free energy of mixing of a polymer chains … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 14 Jul 2016 · 8,457 accessesView PDFCite
