Research ArticleOpen accessIn the abstractShelf-Life Prediction of Specialty Coffees using the Arrhenius ModelFrank Fernández Rosillo, María Alina Cueva Ríos, Lenin Quiñones Huatangari, Carla Guianella Samaniego LalanguiThe study estimated the shelf life of roasted and ground specialty coffees in bi-laminated and tri-laminated packaging concerning cup score, using the Acceleration Test at temperatures of 40, 50, and 60°C. The sensory evaluation was carried out by Q Grader tasters. Based on the higher value of the coefficient of determination of the regressions resulting from the cup and temperature … …OnLine Journal of Biological Sciences, Vol. 23, Issue 1 · 23 Dec 2022 · 6,881 accessesView PDFCite
Research ArticleOpen accessIn the abstractEfficient Implementation of Stochastic Computing Based Deep Neural Network on Low Cost Hardware with Saturation ArithmeticSunny Bodiwala, Nirali NanavatiThis study presents an efficient and rapid implementation of Stochastic Computing (SC) based Deep Neural Network (DNN) on a low-cost hardware platform. The proposed technique uses bipolar signal encoding in stochastic computing which relatively gives low hardware footprint compared to binary computing. Thereinafter, stochastic max function is presented and subsequently used to approximate the hyperbolic tangent activation function in SC. … …Journal of Computer Science, Vol. 16, Issue 11 · 17 Nov 2020 · 6,875 accessesView PDFCite
Research ArticleOpen accessIn the abstractTotal Conductivity of Calcium Iron Borate Glasses Using an Empirical FormulaHossam M. Gomaa, Saeid M. Elkatlawy, Ahmed H. El-DosokeySamples of calcium borate glasses containing iron ions have been prepared with three different concentrations of both boron and iron oxides. X-ray diffraction spectroscopy was performed and results revealed that samples are in good glassy state, with high homogeneity and short range ordered structure. Electrical conductivity was experimentally measured in the temperature range from 300 to 553 K. Conductivity results … …International Journal of Structural Glass and Advanced Materials Research, Vol. 3, Issue 1 · 21 May 2019 · 7,096 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

The evaluation of the convenience of the house purchase needs to consider that technologies in construction have undergone a rapid change in recent times that proposes an approach to … …American Journal of Environmental Sciences, Vol. 11, Issue 5 · 28 Sep 2015 · 7,309 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Biogas Plants by the Application of an Internal Rate of Return and Debt Service Coverage ApproachGiuseppe Bonazzi, Mattia IottiEnergy production using renewable energy has an effect on environmental sustainability and on public expenditure. In fact, this industry is heavily assisted by public support from the European Union and the Italian State. Developing and applying a method to evaluate the return on investment for companies operating in the field of renewable energy allows them to quantify their efficient use … …American Journal of Environmental Sciences, Vol. 11, Issue 1 · 6 Apr 2015 · 7,632 accessesView PDFCite
Research ArticleOpen accessIn the abstractMATHEMATICAL MODELING AND EXPERIMENTAL STUDY ON THIN LAYER HALOGEN DRYER OF STRAWBERRY AND STUDY IT’S EFFECT ON ANTIOXIDANT ACTIVITYAsaad Rehman Saeed Al-Hilphy, Ali Khudhair Jaber AlRikabiThe halogen drying characteristics of strawberry (Fragaria ananassa Duch) slices were investigated. Drying experiments were carried out a three different drying temperatures (60, 70 and 80°C). The effect of drying temperature on the drying rate, drying coefficient, efficiency, effective diffusivity of the strawberry and antioxidant activity were evaluated. The best model for describing the halogen drying process was chosen by … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 4 · 30 Sep 2013 · 7,367 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Energy Aspects of Apple Drying in the Hot-Air and Infrared DryersSeyed Hashem Samadi, Issa LoghmaniehDrying is an energy-intensive process. In general, heating and evaporation require large quantities of energy. This study has been conducted to evaluate analysis for dying apple slices in two drying systems including hot-air convection and infrared drying. The apple samples were dried at temperatures of 90, 120 and 150°C and radiation intensity of 0.22, 0.31 and 0.49 W/cm2 in the … …Energy Research Journal, Vol. 4, Issue 1 · 26 Aug 2013 · 8,009 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimultaneous Thermodynamic and Kinetic Parameters Determination Using Differential Scanning CalorimetryNader Frikha, Mohamed Bouroukba, Eric Schaer, Jean-Leon HouzelotProblem statement: The determination of reaction kinetics is of major importance, as for industrial reactors optimization as for environmental reasons or energy limitations. Although calorimetry is often used for the determination of thermodynamic parameters alone, the question that arises is: how can we apply the Differential Scanning Calorimetry for the determination of kinetic parameters. The objective of this study consists … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 12 Mar 2011 · 7,986 accessesView PDFCite
