noise-induced hearing loss, which is one of the 10 leading occupational diseases, is a debilitating and irreversible disease. during the recent 15-years period (1997-2012), several studies have investigated the association between noise, hearing damage and other side effects of noise in iran. the aim of this study was to review systematically the relevant literature related to noise-induced hea...

The aim of this study is to examine mediating role athlete engagement and mental toughness in the relationship between burnout well-being. Our theoretical model was tested using data collected from 251 university students (103 females 148 males) sports departments aged 18 33 (Mean = 21.73 years, SD 2.23). Participants completed Athlete Burnout Questionnaire (ABQ), Warwick-Edinburgh Mental Well-...

The study was conducted to analyse possible interactions between noise and shift work, and fatigue as a function of age. In a large questionnaire survey, we assessed personal and environmental risk factors related to fatigue. Noise exposure at work (L(Aeq, 8hr)) was measured with personal noise dosimetry. The sample included 254 day and shift workers, and was divided into 2 age groups (<40- and...

Kleene algebra with tests (KAT) is an equational system that extends Kleene algebra, the algebra of regular expressions, and that is specially suited to capture and verify properties of simple imperative programs. In this paper we study two constructions of automata from KAT expressions: the Glushkov automaton (Apos), and a new construction based on the notion of prebase (equation automata, Aeq...

The paper studies the effect of strain-loading sequence on fatigue lifetime and fracture surface topographies in 7075-T651 aluminum alloy specimens. Fatigue tests were performed two ways: (i) constant-amplitude loading (ii) series variable amplitude with non-zero mean strain values. topography fractures was measured over their entire surfaces help an optical confocal measurement system. results...
