Research ArticleOpen accessIn the keywordsElectromagnetic Interference Mitigation for Inverter fed AC DrivesC. Karthikeyan, K. DuraiswamyProblem statement: In switched mode PWM inverter EMI noise occurs during high (dv/dt) transient period. This EMI noise is mitigated using Active Common mode EMI filter in front of the source. Approach: This study proposes a new active common mode Electromagnetic Interference (EMI) filter for switched mode PWM Inverter applications. The proposed filter is based on current sensing and compensation … …American Journal of Applied Sciences, Vol. 8, Issue 10 · 12 Sep 2011 · 7,309 accessesView PDFCite

Research ArticleOpen accessIn the abstractExperimental Investigation on the Failure Mechanism of Bovine Bone by Three-point Bending TestsHua Li, Rujie Gao, Ruiqi Li et al.Bone damage is a common type of sport injury. The loading rate affects the type of fracture and the degree of soft tissue injury. In view of the problem of whole bone bending damage and failure, this paper introduces the test method of bovine bone bending and the mechanism of bending failure under different loading rates is analyzed through experimental … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 3 · 10 Jul 2020 · 6,535 accessesView PDFCite
Case ReportOpen accessIn the abstractRetroperitoneal Hydatid Cyst Masquerading as a Retroperitoneal Cystic TumorK. Hemanth Kumar, Anish Choudhary, Amaresh Aruni, N.V.K.N. KarthikHydatid disease is an endemic disease, with canines the primary host and humans the intermediate host. Liver, spleen and lungs are most common involved organs, but it can involve any organ. Retroperitoneal hydatid cyst are categorised into two types, primary and secondary. Primary retroperitoneal hydatid cyst is rare disease, with most of the cases diagnosed intra-operatively, hence pre-operative high index … …American Journal of Infectious Diseases, Vol. 15, Issue 3 · 29 Aug 2019 · 7,266 accessesView PDFCite

Coley is credited for having been the first to translate the observation of an association between bacterial infections, high fever and cancer remission into a successful cancer treatment. However, it is worth noting that such an association dates back to at least one century before Coley's times; as Wiemann and Starnes from … …American Journal of Immunology, Vol. 13, Issue 2 · 31 May 2017 · 12,281 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Investigation of Compressed Natural Gas Engine for Nitrogen Oxides ReductionP. M. Diaz, B. Durga PrasadProblem statement: This study describes the use of Reformer Gas (RG) to alter NOx emission in a CNG-fueled HCCI engine. Comparison with diesel, natural gas has a very high octane number (≈120) and high auto-ignition temperature (≈600°C). Composed mostly of methane, natural gas is the only common fuel to manifest relatively pure, single-stage combustion. Other fuels have stronger low-temperature reaction … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 15 May 2012 · 7,298 accessesView PDFCite
