The Heckscher-Ohlin-Vanek (HOV) theorem predicts whether a country will be a net exporter of services of a certain factor and the volume of the factor content of trade given the country's and the world's factor endowment information. Recent empirical work has documented that the measured factor content of trade is too small compared to the theoretical prediction and named this special pattern o...

INTRODUCTION Recent studies have demonstrated a strong correlation between obesity, insulin resistance, increased insulin and insulin-like growth factor levels and the risk of breast cancer. Our study was aimed at exploring correlations between glucose, insulin, insulin resistance, obesity and quantitatively estimated breast elasticity in healthy women. MATERIAL AND METHODS The pilot study in...

Evidence from biomechanics research suggests that tendon series elasticity allows muscle to act in an optimal range of its force–length and force–velocity curves to achieve work and power amplification. In this investigation we put forth a simple model to quantify the capacity of series elasticity to increase work and power output from an actuator. We show that an appropriate spring constant in...

BACKGROUND It is known that subjective contours are perceived even when a figure involves motion. However, whether this includes the perception of rigidity or deformation of an illusory surface remains unknown. In particular, since most visual stimuli used in previous studies were generated in order to induce illusory rigid objects, the potential perception of material properties such as rigidi...

Sunflower is one of four main annual oil plants that cultivated in oil and nut varieties. This plant as an important and industrial food product and because of nutritional features and the potential for earning exchange has become a valuable product in foreign and inner markets and has a special position in agricultural sector. Khoy, by producing 40 percent of sunflower productions of country a...
