A micromechanical model is developed for the prediction of growth rate fatigue damage zones in unidirectional fibre composites subjected to cyclic tension-tension loading. The occurs by progressive breaks caused debond crack tip stress fields fibres that have broken earlier load cycles. tips are taken advance along due a slip-induced decrease frictional sliding shear acting debonded parts under...

Inverse first-order reliability method for probabilistic fatigue life prediction of composite laminates under multiaxial loading Yibing Xiang and Yongming Liu* Department of Civil and Environmental Engineering Clarkson University Potsdam NY.13699, USA Abstract: Multiaxial fatigue reliability is a challenging problem despite extensive progress made during the past few decades. Anisotropic materi...

BACKGROUND In primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC) fatigue is a major clinical problem. Abnormal amino acid (AA) patterns have been implicated in the development of fatigue in several non-hepatological conditions but for PBC and PSC no data are available. This study aimed to identify abnormalities in AA patterns and to define their relation with fatigue. ME...

BACKGROUND The purpose of this study was to compare fatigue, depression and quality of life scores in persons with multiple sclerosis who do (Exercisers) and do not (Non-exercisers) regularly participate in physical activity. METHODS A cross-sectional questionnaire study of 121 patients with MS (age 25-65 yr) living in Queensland, Australia was conducted. Physical activity level, depression, ...

OBJECTIVE This study assessed the prevalence and associations of fatigue in systemic lupus erythematosus (SLE). METHODS Questionnaires were used to measure self-reported fatigue, disease activity, sleep quality, quality of life, anxiety and depression in 120 out-patients with SLE. RESULTS Abnormal fatigue was reported by 97 (81%) patients, and 71 (60%) patients reported poor sleep quality. ...

PURPOSE/OBJECTIVES To determine relationships among (a) cancer-related fatigue and meaning in life, (b) overall symptom distress and meaning in life, (c) fatigue and performance, and (d) overall symptom distress and performance in breast cancer survivors. DESIGN Cross-sectional and correlational. SETTING Community-based setting in eastern Pennsylvania. SAMPLE 34 women who had completed th...

conclusions with respect to the findings of the study, this method of treatment is recommended due to being cost efficient, easy, applicable, and flexible for alleviating the effect of fatigue on the personal, psychological, and social aspects of life quality in patients on hemodialysis. results the mean of the fatigue score within the research units was 42.37. overall, 42.2% and 56.1% of the p...

This paper reviews the current literature examining the pervasive symptom of fatigue experienced in three of the most common degenerative neurological conditions: multiple sclerosis (MS), Parkinson’s disease (PD) and post-polio syndrome (PPS). The existing literature can be considered under four headings definition and prevalence, type, cause, impact of fatigue. Fatigue is a common symptom in d...
