Air Atomized Spray with Additives: A Novel Cooling Methodology for the Development of Nanosteel

The effect of varying liquid-solid contact angle on the evaporation time of a single droplet of water deposited on a (AISI-304) steel surface is studied. Mathematical modelling for the evaporation life time of a water droplet added with additives is done. Conventional cooling methodology cools at the rate of around 30oC which is not sufficient enough for the production of Nanosteel. Contact angle is varied in experiments by adding varying amounts (500, 1000 and 1500 ppm) of surfactant, salt and alcohol to the water. The contact angle is measured by Goniometer. Reduction in the contact angle results in increase of the contact area between the droplet and solid surface. Reduction in the contact angle also reduces droplet thickness, enhancing heat conduction through the droplet. Both the effects increase the droplet evaporation rate. Reduction in droplet evaporation life time is achieved by varying the contact angle from 900to 490. Different types of additives were added to water and their effect on the contact angle was calculated

Effects of resveratrol on oxidative stress in high fat diet /streptozocin induced diabetic wistar albino rats

Background: Diabetes mellitus is a common chronic disease. One of the pathophysiology is found to be oxidative stress. This study aims to evaluate the effect of resveratrol on oxidative stress in high fat diet (HFD)/streptozotocin induced diabetic rats.Methods: Wistar albino rats, fed with HFD rendered diabetic with streptozotocin, were divided into 6 groups, namely the diabetic control treated with vehicle (DC), standard control which received metformin (SC), test groups treated with 5,10, and 20 mg/kg b.w. of resveratrol and combination of half dose of metformin and resveratrol (10 mg/kg)(TC). A group of six normal animals served as normal control (NC), another six as HFD control. Fasting blood glucose, lipid profile and serum MDA and SOD were measured one week after induction of diabetes. The animals were then treated orally for 2 weeks after which the same parameters were repeated. The in-vivo results were analysed by one way ANOVA followed by Tukey’s multiple comparison test.Results: The DC group demonstrated a increase in the fasting blood glucose compared to NC, HFD control while a significant decrease in the fasting blood glucose was observed with SC, Test groups (p<0.05) as compared to the DC group. TC showed a significant improvement in dyslipidemia compared to their baseline values (p<0.05). There was significant change in the serum MDA level and SOD activity.Conclusions: Resveratrol improves oxidative stress in diabetic rats

Effect of resveratrol on diabetic neuropathy in wistar albino rats

Background: Type 2 diabetes mellitus (DM) is a common chronic disease with increasing prevalence worldwide. Prolonged uncontrolled hyperglycemia, dyslipidemia are major risk factor for its complication like neuropathy. Since there is no definite treatment for diabetic neuropathy, this study aims to evaluate the effect of resveratrol on diabetic neuropathy in high fat diet with low dose streptozotocin induced type-2 DM model in wistar albino rats.Methods: First type 2 diabetic rat model was established. Wistar albino rats, fed with high-fat diet (HFD) rendered diabetic with streptozotocin, were divided into 6 groups, disease control (DC) treated with vehicle, standard control (SC) which received metformin, test groups treated with 5, 10, and 20 mg/kg b.w. of resveratrol and combination of half dose of metformin and resveratrol (10 mg/kg) (TC). A group of six normal animals served as normal control (NC), another six as HFD control. Fasting plasma glucose, lipid profile were measured one week after induction of diabetes. The animals were then treated orally for 2 weeks after which the same parameters were repeated. Behavioral biomarkers for neuropathy are measured in 4 weeks and 6 weeks of treatment. The in-vivo results were analyzed by one way ANOVA followed by Tukey’s multiple comparison test for biochemical parameters and Kruskal Wallis test followed by Dun’s multiple comparison test for behavioral biomarkers.Results: Increase in fasting plasma glucose (FPG), deranged lipid profile, increased neuropathy in DC compared to NC, HFD control while a significant decrease in FBG, improved pain behavior with SC, test groups (p&lt;0.05) as compared to the DC group.Conclusions: Resveratrol prevents diabetic neuropathy

SHOULD ECOLOGICAL ENTREPRENEURS IGNORE THE EQUITY OF DEVELOPMENT? INSIGHTS FROM THE SATYAMEV JAYATE WATER CUP BY PAANI FOUNDATION

What should be the right approach to water harvesting and management: (1) convenience,(2) prudence, or (3) the integration of both? The convenience approach refers to the tendency of governments and organizations to focus largely on increasing the supply of water without telling citizens to use water rationally. The prudence approach insists on the minimal and judicious use of water, something governments seldom tell citizens for the fear of losing popularity. The integration approach absorbs the best methods and technology available to intervene in the supply as well as demand side of water. With a focus on the integration approach, this study undertakes a case analysis of the Satyamev Jayate Water Cup (SJWC) by Paani Foundation that converted many draught-prone regions of the Maharashtra state of India into water-sufficient and prosperous zones by utilizing low-cost, indigenous knowledge systems and eco-friendly measures. The study aims to highlight the limitations of this massive socio-ecological campaign in the context of water management and governance

Azimuthal anisotropy of charged jet production in root s(NN)=2.76 TeV Pb-Pb collisions

We present measurements of the azimuthal dependence of charged jet production in central and semi-central root s(NN) = 2.76 TeV Pb-Pb collisions with respect to the second harmonic event plane, quantified as nu(ch)(2) (jet). Jet finding is performed employing the anti-k(T) algorithm with a resolution parameter R = 0.2 using charged tracks from the ALICE tracking system. The contribution of the azimuthal anisotropy of the underlying event is taken into account event-by-event. The remaining (statistical) region-to-region fluctuations are removed on an ensemble basis by unfolding the jet spectra for different event plane orientations independently. Significant non-zero nu(ch)(2) (jet) is observed in semi-central collisions (30-50% centrality) for 20 <p(T)(ch) (jet) <90 GeV/c. The azimuthal dependence of the charged jet production is similar to the dependence observed for jets comprising both charged and neutral fragments, and compatible with measurements of the nu(2) of single charged particles at high p(T). Good agreement between the data and predictions from JEWEL, an event generator simulating parton shower evolution in the presence of a dense QCD medium, is found in semi-central collisions.

Pseudorapidity and transverse-momentum distributions of charged particles in proton-proton collisions at root s=13 TeV

The pseudorapidity (eta) and transverse-momentum (p(T)) distributions of charged particles produced in proton-proton collisions are measured at the centre-of-mass energy root s = 13 TeV. The pseudorapidity distribution in vertical bar eta vertical bar <1.8 is reported for inelastic events and for events with at least one charged particle in vertical bar eta vertical bar <1. The pseudorapidity density of charged particles produced in the pseudorapidity region vertical bar eta vertical bar <0.5 is 5.31 +/- 0.18 and 6.46 +/- 0.19 for the two event classes, respectively. The transverse-momentum distribution of charged particles is measured in the range 0.15 <p(T) <20 GeV/c and vertical bar eta vertical bar <0.8 for events with at least one charged particle in vertical bar eta vertical bar <1. The evolution of the transverse momentum spectra of charged particles is also investigated as a function of event multiplicity. The results are compared with calculations from PYTHIA and EPOS Monte Carlo generators. (C) 2015 CERN for the benefit of the ALICE Collaboration. Published by Elsevier B.V.

Elliptic flow of muons from heavy-flavour hadron decays at forward rapidity in Pb-Pb collisions at root s(NN)=2.76TeV

The elliptic flow, v(2), of muons from heavy-flavour hadron decays at forward rapidity (2.5 <y <4) is measured in Pb-Pb collisions at root s(NN)= 2.76TeVwith the ALICE detector at the LHC. The scalar product, two- and four-particle Q cumulants and Lee-Yang zeros methods are used. The dependence of the v(2) of muons from heavy-flavour hadron decays on the collision centrality, in the range 0-40%, and on transverse momentum, p(T), is studied in the interval 3 <p(T)<10 GeV/c. A positive v(2) is observed with the scalar product and two-particle Q cumulants in semi-central collisions (10-20% and 20-40% centrality classes) for the p(T) interval from 3 to about 5GeV/c with a significance larger than 3 sigma, based on the combination of statistical and systematic uncertainties. The v(2) magnitude tends to decrease towards more central collisions and with increasing pT. It becomes compatible with zero in the interval 6 <p(T)<10 GeV/c. The results are compared to models describing the interaction of heavy quarks and open heavy-flavour hadrons with the high-density medium formed in high-energy heavy-ion collisions.
