The practical problems that usually come up during the on-vehicle testing of motor car shock absorbers have been discussed. Results example tests carried out to EUSAMA standard procedure were compared test results obtained with using newer methods, i.e. phase angle method and half power bandwidth (HPBM). issue incompatibility typical excitation applied by diagnostic suspension testers one often...
Donnino and colleagues provide new insights into the field of oxidative stress and mitochondrial dysfunction during septic shock. These authors suggest a coenzyme Q10 (CoQ10) deficiency in patients with septic shock. Larger prospective observational trials measuring CoQ10 in patients with septic shock are required to confirm the possibility of CoQ10 depletion. This study is a new step toward a ...
In this work the reliability of a Micro-Electro-Mechanical Systems (MEMS) microphone is studied through two accelerated life tests, mixed flowing gas (MFG) testing and shock impact testing. The objective is to identify the associated failure mechanisms and improve the reliability of MEMS devices. Failure analyses are carried out by using various tools, such as optical microscopy, scanning elect...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
BACKGROUND The placement of an implantable cardioverter defibrillator (ICD) has become routine practice to protect high risk patients from sudden cardiac death. However, implantation-related myocardial micro-damage and its relation to different implantation strategies are poorly characterized. METHODS A total of 194 ICD recipients (64±12 years, 83% male, 95% primary prevention of sudden cardi...
