Research ArticleOpen accessEvery word in the titleTesting Composite Valve Covers for Reciprocating Engine ApplicationsPeng Hao Wang, Natalie ZimmermannThe use of composites within the aeronautical field is not limited to airframe applications and includes powerplant components in reciprocating engines. To add to the research body in this area, the presented work aimed to evaluate the performance of novel carbon fiber valve covers installed on an aircraft reciprocating engine. Specifically, the comparative performance between novel composite-based valve covers and … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 3 · 12 Aug 2022 · 5,836 accessesView PDFCite
Literature ReviewOpen accessEvery word in the titleMycobacterium Abscessus Native Tricuspid Valve Endocarditis. Is a Six-Week Course of Combination Antibiotic Therapy Enough?Rabindra Ghimire, Dora Lebron, William Matthew Wooten et al.A 24-year-old Caucasian woman with a history of intravenous drug abuse and multiple hospital admissions for substance abuse related medical problems presented with pneumonia and was discharged home on oral antibiotics. Three days later, her blood culture grew acid fast bacilli, which was subsequently identified as M. abscessus subspecies abscessus. Transthoracic and transesophageal echocardiogram (TTE and TEE respectively) was suggestive … …American Journal of Infectious Diseases, Vol. 16, Issue 1 · 20 Feb 2020 · 7,281 accessesView PDFCite

Research ArticleOpen accessIn the keywordsDynamics of Mechanisms with Cams Illustrated in the Classical DistributionRelly Victoria Virgil Petrescu, Raffaella Aversa, Bilal Akash et al.The paper presents an original method to determine the general dynamics of rotating cam and lifting, customized to flat-plate mechanism. First, the dynamic cinematic is presented. Then the Lagrange equation is resolved and with an original dynamic model with a degree of freedom with variable internal damping the dynamic analysis of two models is then made. The mechanisms presented, scientifically … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 5 Jun 2017 · 8,491 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOperational Fault Diagnosis in Industrial Hydraulic Systems Through Modeling The Internal Leakage of its ComponentsP. Athanasatos, D. Koulocheris, T. Costopoulos, K. RaptisIn this study, a model of a high pressure hydraulic system was developed using the bond graph method to investigate the effect of the internal leakage of its main components (pump, cylinder and 4/2 way valve) on the operational characteristics of the system under various loads. All the main aspects of the hydraulic circuit (like the internal leakages, the compressibility … …American Journal of Applied Sciences, Vol. 10, Issue 12 · 7 Nov 2013 · 7,247 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAnalysis of Eco friendly Refrigerants Usage in Air-ConditionerC. Chinnaraj, R. Vijayan, P. GovindarajanProblem statement: There are two types of global warming contributions through refrigeration and air conditioning systems. The first one is the Direct Global Warming Potential (DGWP) due to the emission of refrigerants and their interaction with heat radiation. The second one is the Indirect Global Warming Potential (IDGWP) due to the emission of Carbon Dioxide (CO2) by consuming the energy … …American Journal of Environmental Sciences, Vol. 7, Issue 6 · 27 Dec 2011 · 8,462 accessesView PDFCite
