For the sake of improving product quality and economy, a series cold-pressing experiments were carried out to investigate material properties engineered wood flooring with emulsion polymer isocyanate adhesive. Effect pressing time, pressure, adhesive spreading rate on modulus elasticity (MOE) rupture (MOR) was analyzed based orthogonal experimental design. According results, both MOE MOR positi...

Introduction: To study the effects of exercise, how important it is to choose a posture? We aimed to characterize the possible impact of different body positions on cardiovascular parameters during and after sustained isometric handgrip (IHG) exercise. Materials and Methods: Cross sectional study was carried out in 33 young adult males (mean age: 19.21±1.083 years). We recorded Bloo...

osmotic dehydration under discontinuous reduced pressure is one of the new methods of preparation fruits and vegetable processing with in view of good health. processing of foods at high temperatures used to cook them can cause the formation of carcinogenic substances like acrylamide, and this risk remains even if the trans-fat is removed. the low temperatures employed in this method resulted i...

The reactions of allylic radicals have the potential to play a critical role in molecular weight growth (MWG) kinetics during hydrocarbon oxidation and/or pyrolysis. Due to their stability (when compared to alkyl radicals), they can accumulate to relatively high concentrations. Thus, even though the rate coefficients for their various reactions are small, the rates of these reactions may be sig...

Increased left ventricular (LV) twist and untwisting rate (LV twist mechanics) are essential responses of the heart to exercise. However, previously a large variability in LV twist mechanics during exercise has been observed, which complicates the interpretation of results. This study aimed to determine some of the physiological sources of variability in LV twist mechanics during exercise. Sixt...

To evaluate the influence of oral verapamil (80 and 120 mg) on angina threshold, coronary blood flow, myocardial oxygen consumption and left ventricular function, we subjected 13 patients with effort angina and fixed obstructive coronary artery disease to atrial pacing at progressively higher heart rates. After 120 mg of verapamil, the time to onset of angina and the heart rate at the onset of ...

Purpose. This study investigated the anthropometric indices associated with variations in cardiovascular parameters among primary school pupils in Ile-Ife. Method. One thousand and twenty-six pupils (age range 6-14 years, mean age 10.12 years) from ten schools were recruited with parents' informed consent. Anthropometric (Height (Ht), Weight (Wt), Abdominal Circumference (AC)) and cardiovascula...

OBJECTIVES We examined whether enhanced external counterpulsation (EECP) improves myocardial ischemia, exercise tolerance and cardiac function in patients with coronary artery disease (CAD). BACKGROUND Enhanced external counterpulsation reduces angina and improves exercise tolerance in patients with CAD. Some objective improvements of ischemia by EECP have been reported, but they should be co...

T he onset of ischemia is thought to occur when myocardial oxygen demand exceeds supply. In an individual patient the ischemic threshold might be a reproducible measure that could be used in the short term to establish the efficacy of therapy. In clinical studies the operational definition of the onset of ischemia has been 0.1 mV of ST depression on the electrocardiogram. In earlier investigati...
