Introduction: This study aims to determine the amount of hand-arm vibration transmitted from heavy electric destruction tools and the effect of using chisel with different lengths and shapes when demolishing concrete surfaces. Material and Methods: To evaluate the magnitude of hand-arm vibration on the left and right handles of two powerful electric demolition hammers commonly applied in Irani...

Abstract Background and Aims Acute kidney injury (AKI) is a life-threatening condition. The absence of oxygen during the acute ischemic phase would disturb energy metabolism cause tubular epithelial cell damage. Fatty Acid Oxidation (FAO) main source production renal proximal cells. Timely promoting FAO, increasing supplies energy, proliferation are essential to improve injury, but there no cli...

objective(s) several studies have reported improved response of exercised hearts to myocardial infarction (mi). this study was aimed to evaluate the preventive role of treadmill exercise and diosgenin on cardiac marker enzymes, thiobarbituric acid reactive substances (tbars), total antioxidant status (tas), lipids, and electrocardiographic (ecg) patterns in isoproterenol (iso)-induced myocardia...

Exposure to vibration transmitted to the hands and arms may increase the risk of developing chronic disorders. Current ISO standards regarding exposure are based in part upon assumptions regarding the relationship between threshold measurements and subjective experiences of vibration at higher intensity levels. This study investigated this relationship by comparing absolute threshold levels at ...

Dieser Konferenzbeitrag stellt Erfolgsfaktoren und Misserfolgsfaktoren der Anwendungsentwicklung dar. Grundlage hierfür bilden empirische Untersuchungen des Jahres 2009. Diese Erfolgsund Misserfolgsfaktoren werden anhand der Klassifikation der ISO / IEC 12207 und ISO / IEC 15288 gruppiert und diskutiert. 1 Hintergrund und Basis des vorliegenden Konferenzbeitrags Dieses Paper basiert auf empiris...

BACKGROUND Deletion of the entire AZFb interval from the Y chromosome is strictly associated with azoospermia arising from maturation arrest during meiosis. Here, we describe the exceptional case of an oligozoospermic man, 13-1217, with an AZFb + c (P5/distal-P1) deletion. Through the characterization of this patient, and two AZFb (P5/proximal-P1) patients with maturation arrest, we have explor...

Information Security (IS) specialists’ training for all sectors of trade, industry and government has never been more important as intellectual property and other sensitive or business-critical information becomes the life-blood of many companies today. Analysis of the experience collected within training of IS specialists at the Moscow Engineering Physics Institute (State University) (the MEPh...

Objective(s) Several studies have reported improved response of exercised hearts to myocardial infarction (MI). This study was aimed to evaluate the preventive role of treadmill exercise and diosgenin on cardiac marker enzymes, thiobarbituric acid reactive substances (TBARS), total antioxidant status (TAS), lipids, and electrocardiographic (ECG) patterns in isoproterenol (ISO)-induced myocardi...
