Research ArticleOpen accessIn the abstractEffect of Different Cycles of Thermal Fatigue in Steel Metallurgical Aspects ASTM SA-516 Grade 60Eder Hermes Bicharra, Jorge Luis Braz Medeiros, Luciano Volcanoglo Biehl et al.The ASTM SA-516 steel has applications in compact steam boilers of low and medium temperature and pressure. Deterioration can show when exposed to high temperatures due to fuel gases burning. Failures detected by inspections done in a frequency required by standard on the boilers. Among the main failure mechanisms found in materials used in boilers, creep, corrosion, when subjected to … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 3 · 28 Aug 2020 · 6,985 accessesView PDFCite
Research ArticleOpen accessIn the abstractSildenafil in the Treatment of Postoperative Hypoxemia with High Resistance in Cyanotic Congenital Heart DiseaseZhou Jiawang, Lv Yong, Hu Zhendong et al.This study was designed to determine the effect of sildenafil treatment on postoperative hypoxemia with high resistance in cyanotic congenital heart disease. A total of 247 cases of cyanotic congenital heart disease were operated on from May 2006 to August 2014. Only 45 cases exhibited postoperative hypoxemia after symptomatic treatment. Sildenafil at doses of 0.30-5 mg/kg every 6 h was … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 3 · 1 Sep 2017 · 7,682 accessesView PDFCite
Research ArticleOpen accessIn the abstractFluid-Solid Coupling Analysis on Evolution of In-Situ Stress Field by Water Injection in OilfieldJianjun Liu, Yongxiang Zheng, Bohu Zhang et al.Water injection in oilfield may break initial balance of reservoir and lead to re-distribute of stress and deformation of strata. For further research of the evolution characteristics of in-situ field by water injection, the influence on reservoir by water injection was analyzed and different variables were set to study the effects of depth, injection-withdraw ratio and elastic modulus on strain … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 6 May 2017 · 8,061 accessesView PDFCite
Review ArticleOpen accessIn the abstractAbout Boeing X-32Relly Victoria Virgil PetrescuThe Boeing X-32 is a demonstration jet designed for the Joint Strike Fighter contest. He lost the Lockheed Martin X-35 demonstrator, which was further developed in the Lockheed Martin F-35 Lightning II. Boeing's competitive advantage has been to provide considerably lower costs of production and lifecycle by minimizing variations between different versions of the JSF. Therefore, the X-32 was designed … …Journal of Aircraft and Spacecraft Technology, Vol. 3, Issue 1 · 1 Apr 2019 · 9,960 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of the Thermodynamic Equilibrium of Fragrance Mixtures, Limonene, Linalool and Geraniol, using the Unifac and Cosmo-Sac Models and the Estimation of their Combined Properties in Binary, Ternary and Quaternary MixturesLavínia Mota Cristianismo Silva, José Izaquiel Santos da Silva, Rogério Alexandre Alves de Melo, Edilailsa Januário de MeloPerfume is a non-ideal complex mixture of chemicals originating from the extraction of essential oils and these oils are volatile components extracted from plants, some animals, or even synthesized. For this reason, to compose a fragrance, there are countless possibilities to combine one element and another, which makes the process slow and expensive. Therefore, in this study, we will combine … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 2 · 14 Jun 2022 · 7,454 accessesView PDFCite
EditorialOpen accessIn the abstractProtecting crop species from biotic and abiotic constraints in the era of Global Change: are we ready for this challenge?Marco Landi, Giovanni BenelliReliable and affordable supply of food is of crucial importance to the progress and stability of human societies. During the last century, we have assisted to an extraordinary increase of crop yields, especially for the most widespread and consumed crop species, such as rice, wheat, corn and soybean. The Broadbalk experiment, one of the oldest continuous agronomic experiments in the … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 2 · 4 Jun 2016 · 8,399 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Use of the Super Absorbent Polymer as Water Blocker in Concrete StructuresMoayyad Al-Nasra, Mohammad Daoudb, Taher M. Abu-LebdehAdding super absorbent polymer to the concrete mix improves the performance of the concrete in its both stages; fresh concrete and hardened concrete. The super absorbent polymer has the ability to absorb relatively large amount of water and convert it into gel at the same time the volume increases proportionally. The new modified concrete has the ability to retain water … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 6 Nov 2015 · 8,932 accessesView PDFCite
EditorialOpen accessIn the abstractThe Food Additives Nitrite and Nitrate and Microbiological Safety of Food ProductsStefanie Müller-Herbst, Anna Mühlig, Jan Kabisch et al.In Germany, raw sausages are typically produced according to a technology referred to as hurdle technology (Leistner, 2000). The combination of several stressful conditions should successfully inhibit growth and survival of pathogenic bacteria, which can be regularly found in raw pork or beef material (Mataragas et al., 2008; Rhoades et al., 2009). Hurdles applied during raw sausage fermentation are the … …Current Research in Microbiology, Vol. 6, Issue 1 · 29 Jun 2015 · 10,378 accessesView PDFCite
InvestigationOpen accessIn the abstractEffects of Recombinant Toxin Phospholipase D in Cardiac Muscle of RatsJoao Victor Capelli Peixoto, Fernando Augusto Lavezzo Dias, Carlos Estevan Nolf Damiani et al.Loxoceles spiders gender are worldwide spread and its bites can cause dermonecrosis or even a systemic effect (hemolysis, kidney and liver injury). It is believed that phospholipase D, the main component present in the venom, could be responsible for the injury. In this study, we used a recombinant form of phospholipase D (rLiD1) and evaluated its direct and systemic effects … …American Journal of Pharmacology and Toxicology, Vol. 10, Issue 1 · 2 Jun 2015 · 6,956 accessesView PDFCite
Research ArticleOpen accessIn the abstractTHE HIGH VOLUME REUSE OF HYBRID BIOMASS ASH AS A PRIMARY BINDER IN CEMENTLESS MORTAR BLOCKCheah Chee Ban, Noor Shazea Ahmad Nordin, Part Wei Ken et al.High Calcium Wood Ash (HCWA) and Pulverised Fuel Ash (PFA) are by-products from the wood biomass and coal energy production which are produced in large quantity with combined annual production of 500 million tonnes. This poses a serious problem for disposal of the waste material especially at places where land is scarce. The prescribed study was aimed to examine the … …American Journal of Applied Sciences, Vol. 11, Issue 8 · 29 May 2014 · 7,162 accessesView PDFCite
