Research ArticleOpen accessEvery word in the titleCreep-Fatigue Crack Growth Interaction in Nickel Base Supper AlloyF. DjavanroodiMost engineering components which operate at elevated temperatures are subjected to non-steady loading during service. This paper describes the current fracture mechanics concepts that are employed to predict cracking of Nickel base supper alloy materials at high temperatures under low and high frequency cyclic loading. A model for predicting creep crack growth in terms of C* and the creep uniaxial … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 6,892 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLaboratory Diameteral Fatigue Performance of Stone Matrix Asphalt with Cellulose Oil Palm FiberRatnasamy Muniandy, Bujang B.K. HuatStone Matrix Asphalt (SMA) is a gap-graded mix that is gaining popularity worldwide. Generally, gap graded mixes are thought to be weak in fatigue resistance. In this study, cellulose fibers were pre-blended in PG64-22 binder with fiber proportions of 0.2%, 0.4%, 0.6%, 0.8% and 1.0% by weight of aggregates. The fiber-modified binder showed improved rheological properties and showed that the … …American Journal of Applied Sciences, Vol. 3, Issue 9 · 30 Sep 2006 · 8,979 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTHE ADVERSE EFFECT OF STEEL PARTICLE CONTAMINANTS ON FATIGUE LIFE OF GREASE LUBRICATED BALL BEARINGSA. Stathis, Th. Costopoulos, D. Koulocheris, K. RaptisThe rating life of ball bearings is reduced when hard particle contaminants are present in the lubricant. Usually, this life reduction is taken into account in the calculation of modified rating life by using the contamination factor through a general characterization of the lubrication conditions. However, the impact of contaminant’s variables such as size, hardness and concentration level has to … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 14 Jul 2014 · 6,991 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFinite Element Analysis of Plasticity- Induced Fatigue Crack Closure with Singular ElementR. Rahgozar, H. Saffari, R. TabatabaeiDeveloping a new method is presented to compute crack opening values in planar geometries using the crack surface nodal force distribution under minimum loading as determined from finite element analyses (FEM). In this technique, two-dimensional elastic-perfectly plastic finite element analyses of middle-crack tension (MT) geometry is conducted to study fatigue crack closure and to calculate the crack opening values under … …American Journal of Applied Sciences, Vol. 4, Issue 6 · 30 Jun 2007 · 6,850 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAnalytic and Nonlinear Prognostic for Vehicle Suspension SystemsAbdo Abou Jaoude, Khaled El-TawilPredicting Remaining Useful Lifetime (RUL) of industrial systems becomes currently an important aim for industrialists knowing that the expensive failure can occur suddenly. As the classical strategies of maintenance are not efficient and practical because they neglect the evolving product state and environment, the recent prognostic approaches try to fill this gap. This approach shows to be important in ensuring … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 1 · 23 Feb 2013 · 7,522 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAre Improvements in Physical Fitness after an Exercise Program Related to the Symptomatology in Patients with FibromyalgiaBorja Sanudo, Luis Carrasco, Moisés de Hoyo, Nicolae OchianaProblem statement: Physical exercise is considered one of the main strategies in management of Fibromyalgia (FM); While many studies have shown relevant improvements in the patients’ physical condition and psychological status, the efficacy of these treatments have not yet been completely determined and whether or not these improvements are related with symptom severity is still debated. The aim of this … …Journal of Social Sciences, Vol. 7, Issue 3 · 18 Jul 2011 · 7,653 accessesView PDFCite
Research ArticleOpen accessIn the abstractReal-Time Monitoring and Injury Risk Warning Algorithm Based on Data Fusion of Motor Muscle ContractionGuomin Wang, Jingying HuangThe existing sports injury warning algorithms are difficult to achieve dynamic injury risk modeling based on individual muscle characteristics while ensuring real-time fusion efficiency of multimodal signals. This article proposes a real-time muscle contraction state perception and injury risk warning algorithm based on adaptive weighted feature fusion and lightweight temporal modeling. The system synchronously collected surface electromyography (sEMG), Inertial Measurement … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 10 Aug 2026 · 1,089 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of CTLA-4 Inhibitor Combined with Chemotherapy on Immunoglobulin Levels and General Condition in Breast Cancer PatientsRuiguang CaiThis study conducted an evaluation of the CTLA-4 inhibitor ipilimumab plus standard chemotherapy on immunoglobulin levels, performance status, and Quality of Life (QoL) in patients with stage I-III Breast Cancer (BC) via a randomized controlled trial. 120 patients with stage I-III BC were randomly allocated to the experimental group (chemotherapy + ipilimumab) and the control group (chemotherapy), and the treatment … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 2 · 3 Jul 2026 · 1,115 accessesView PDFCite
Review ArticleOpen accessIn the abstractCOVID-19: A Review of Current Evidence on Phylogenetics and EtiopathogenesisRafiq Shajahan, Naganathan K. PillaiCOVID-19 represents the latest pandemic caused by the SARS-CoV-2 coronavirus. Coronaviruses are RNA viruses that cause a largely viral mediated immune-related syndrome similar to the SARS epidemic. Following metagenomic sequencing, SARS-CoV-2 closely resembles SARS-CoV (79% similarity) and MERS-CoV virus (50% similarity). Despite this, clinical observations have found varying degrees of infectivity and pathogenesis amongst these viruses. Phylogenetic origins of SARS-CoV-2 … …American Journal of Infectious Diseases, Vol. 17, Issue 1 · 2 Apr 2021 · 6,764 accessesView PDFCite
