the growth of the electrical energy consumption form one side and the bounded available fossil fuel and other limitations from the other side, makes the thermal power plants upgrading as a main demand in the world. decreasing the internal energy consumption, increasing the performance and the output power with the minimum costs are the important targets of the power plants retrofitting. nowaday...

Presents a photograph of the WindBox turbine which is installed on roof building in Rouen, France. It 1.6 meters tall, and has 4-square-meter footprint (leaving plenty space for solar panels or tiles). The unit, weighs 130 kilograms, can generate up to 2,500 kilowatt-hours electricity per year (enough meet roughly one-quarter energy needs typical U.S. household).

This study measured the contents of the ionic and elemental constituents, and the chemical compounds containing in windbox (WB) dusts collected from a commercial iron ore sintering plant, then the results were used to identify possible PCDD/Fs formation pathways in the WB. We found that the abundance in both KCl and NaCl may provide a suitable condition for de novo synthesis of PCDD/Fs in the W...

Forty subjects, 20 women and 20 men, were exposed to airflows from five different directions: horizontally towards the front, the back, and the left side and vertically upwards and downwards. The subjects were exposed to stepwise increased air velocities ranging from less than 0.10 m/s to 0.40 m/s at three temperature levels 20, 23 and 26 o C. The results showed that airflow direction has an im...

vasomotor hot flash is the most common and distressful complication of menopausal women. its treatment is the most frequent clinical challenge. as a result, an effective and harmless therapy is needed. this double-blind controlled clinical trial was conducted to determine the effects of licorice roots on the relief and recurrence of hot flash in menopausal women referring to the healthcare cent...

Spices are the most attractive ingredients to confer an authentic taste to food. As they are derived from plants, they harbour allergenic potency and can induce symptoms ranging from mild local to severe systemic reactions. Due to the content of pharmacologically active substances of spices, the diagnosis of allergy and the differentiation from intolerance reactions may be difficult. Associatio...
