Research ArticleOpen accessIn the keywordsThermoelectric and Optical Properties of Advanced Thermoelectric Devices from Different Multilayer Thin FilmsMebougna Drabo, Satilmis BudakThermoelectric devices were prepared using different multilayered thin film structures in the order of Ge/Si+Ge, Si+Ge, Si, Sb+Ge, Ge and SiO2/SiO2+Ge by DC/RF Magnetron Sputtering. The thickness of the deposited thin films were measured using Filmetrics UV thickness measurement system. The prepared thermoelectric devices have been modified with 5 MeV Si ions bombardments at the different fluences (doses) using Pelletron … …American Journal of Applied Sciences, Vol. 16, Issue 8 · 29 Aug 2019 · 8,119 accessesView PDFCite
Research ArticleOpen accessIn the keywordsHighly-Efficient Advanced Thermoelectric Devices from Different Multilayer Thin FilmsSatilmis Budak, Zhigang Xiao, Barry Johnson et al.The efficiency of the thermoelectric materials and devices is shown by the dimensionless Figure of merit, ZT. ZT is calculated by multiplying the Seebeck coefficient with square of the electrical conductivity and absolute temperature and dividing it all by the thermal conductivity. Thermoelectric devices were prepared using different multilayered thin film structures in the order of SiO2/SiO2 + Ge/Ge/Sb + … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 27 Apr 2016 · 8,372 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Novel Interconnect Structure for Elmore Delay Model with Resistance-Capacitance-Conductance SchemeUma Ramadass, Krishnappriya, Jebashini Ponnian, P. DhavachelvanIn this brief, we present a simple close-form delay estimate, based on first and second order moments that handle arbitrary voltages and conductance effects for a lumped and distributed line. This proposed model introduces a simple tractable delay formula by incorporating conductance (G) into Resistance, Capacitance (RC) network by preserving the characteristics of the Elmore delay model. The RCG model … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 7,054 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSimulation and Optimization of Perovskite Type Micro Thermoelectric GeneratorJeyashree Yesuraj, Vimala Juliet Ashokan, Sukhi Yesuraj, Rebecca Shirly Harrison ChristleyIn this study the thermoelectric properties of perovskite type Ca-Mn-O3 compounds are estimated for the operating range of 850-1150 K. The optimization of design module for maximum power output is obtained using the analytical expression for power of Thermoelectric Generator (TEG). For the optimum length of 1.4 μm and with a cross sectional area of 0.3×0.3 μm the power obtained … …American Journal of Applied Sciences, Vol. 13, Issue 11 · 26 Nov 2016 · 7,385 accessesView PDFCite
Research ArticleOpen accessIn the abstractEfficiency of Nitrogen Fixation by Rhizobium Strains Associated With White Clover in the Ecuadorian Highlands Biological Nitrogen Fixation by White Clover in EcuadorDaniela Michell Chuquimarca Mamarandi, Venancio Saúl Arahana Bonilla, Paulina Andrea Cevallos Hidalgo et al.The objective of this research was to evaluate the nitrogen-fixing capacity of 30 strains of Rhizobium isolated from white clover nodules, collected in the provinces of Pichincha and Cotopaxi under greenhouse conditions. After isolation of the bacteria and authentication of the isolates, a greenhouse experiment was conducted, in a Completely Randomized Design (CRD), with three replications and two controls: with … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 4 Oct 2026 · 850 accessesView PDFCite
Research ArticleOpen accessIn the abstractGilsonite Modified Asphalt for Use in Pavement ConstructionAliasghar Akbari Nasrekani, Mostafa Nakhaei, Koorosh Naderi et al.Properties such as durability and moisture resistance of asphalt concrete significantly improve pavement service life. When siliceous aggregate is used, then preventing moisture damage and stripping become distinctly required. Typically, stripping could be prevented by either using antistripping agents or by modifying the binders. The anti-stripping agent achieve its purpose by changing the aggregates' affinity for water through changing the … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 3 Apr 2018 · 9,387 accessesView PDFCite
EditorialOpen accessIn the abstractChasing the Fat Demon: Fat Chance, Buddy?David L. Katz, Joachim Storsberg, Christian SchmidtScience is an interesting profession. At times, one could get caught up in his or her own world of thoughts, perception, far away from reality, sometimes referred to as the proverbial ivory tower (Lederberg, 1972). Science for the sake of science is, per se, not without merit, with our fragmented understanding of a given issue providing ample justification for experimentation … …American Journal of Immunology, Vol. 13, Issue 2 · 29 May 2017 · 8,137 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimal Subsurface Appraisal: A Key Link to the Success of Development Projects-Few ExamplesVirendra Singh, Ivan Yemez, Elena Izaguirre, Alvaro RaceroDuring exploration and production phases, the life of a hydrocarbon field can be distinguished by five main stages: Exploration, appraisal, development, production and abandonment. Of particular interest is the appraisal stage, where billions of dollars are spent across the oil and gas industry on data gathering activities with a view to reducing subsurface uncertainties towards optimizing reservoir development and management. … …American Journal of Applied Sciences, Vol. 14, Issue 2 · 13 Jan 2017 · 8,522 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvolution of Creation Buddhist Lent Candle of Work Awarded in Ubon Ratchathani’s Lent Candle Contests 2003-2007Sakchai UttithoThe tradition of Lent candle procession at the Buddhist Lent festival is the grand festival at the national level in Ubon Ratchathani province. From the merit-making tradition concerning Buddhism binding to the way of life of Isan people for the long time, this festival has developed to be a tourist festival at the national level. Later, there have been contests … …American Journal of Applied Sciences, Vol. 9, Issue 11 · 1 Sep 2012 · 6,549 accessesView PDFCite
