nowadays, utilization of blended fuel in internal combustion engine is one of main topics in vehicle industries. the synergy effect will be highlighted when the potential of each fuel is employed and the engine performance will improve consequently.  in this research, the laminar flame speed of methane (main component of reference fuel for natural gas) and isooctane (main component of reference...

objective: type 2 diabetes mellitus (dm-2) is a chronic and progressive metabolic disorder known as a serious threatening condition in the individual and society. type 2 diabetes mellitus is known as the major cause of cardiovascular diseases (cvd). contradictory evidences about the effect of omega-3 fatty acids on cvd risk factors, particularly hypertension. the aim of this study was to determ...

Stroke is a major cause of disability in the US, leaving most survivors with abnormal motor function, often resulting in hemiparetic gait. Quality of gait in this population has been well characterized by measures of velocity, though velocity alone provides only a general index of functional mobility. Researchers and clinicians should continue to develop a complete characterization of behaviora...

BACKGROUND Equipment, physiologic, and technique factors can influence the accuracy of blood pressure measurement. The current study was designed to isolate certain technique factors and then assess the accuracy of nursing personnel measurements of blood pressure in three residency family practice centers. METHODS An experienced registered nurse was trained in applying the American Heart Asso...

The development of a sensor that can measure balance during quiet standing and predict stepping response in the event of perturbation has many clinically relevant applications, including closed-loop control of a neuroprothesis for standing. This study investigated the feasibility of an algorithm that can predict in real-time when an able-bodied individual who is quietly standing will have to ma...

Even though frequency analysis of body sway is widely applied in clinical studies, the lack of standardized procedures concerning power spectrum estimation may provide unreliable descriptors. Stabilometric tests were applied to 35 subjects (20-51 years, 54-95 kg, 1.6-1.9 m) and the power spectral density function was estimated for the anterior-posterior center of pressure time series. The media...

This study examined differences in center of pressure (COP) trajectories between shod and barefoot running. Ten habitually shod runners ran continuous laps under both shod and barefoot conditions. The COP trajectory was calculated in the global coordinate system but then transformed to the anatomic coordinate system of the foot. The anterior-posterior and medio-lateral positions and excursions ...

pressure refers to the feelings an athlete has about performing in a competitive situation. the primary aim of this study was to examine kinematic changes of tennis serves in increasing competitive pressure. 20 semi-professional right-handed male tennis players completed 120 serves under low (normal) and high competitive pressure phases. pressure checks (heart rate and perceived competitive sta...
