Synthesis of silica supported ni and cu catalyst for carbon dioxide methanation reaction حسب Aheed, Ahmed

"…In addition, the used catalysts after the reaction were characterized using similar techniques to evaluate the effect of reaction conditions on active phase and SiO2 support. The 1%Ni on SiO2 catalyst shows good activity for CO2 conversion to CH4 till 450ºC, thereafter CH4 formation decreased and CO increased and remains the only product at 650ºC. …"

Spatio-temporal changes in water-related ecosystem services provision and trade-offs with food production حسب Shiliang, Yang

"…The results showed that: 1) food production increased from 0.497×108tons to 0.798×108tons despite area of cultivated land decreasing from 23.61×104km2 to 23.40×104km2 during the study period (2000–2015). 2) Water yield and soil retention both showed a downward trend, while nitrogen and phosphorus exports showed an increasing trend, in 2000–2015.3) Food production showed a trade-off relationship with soil retention and water yield, but a synergistic relationship with nitrogen and phosphorus export. …"

Warming up for athletic events حسب Hussain, Helmi

"…Coaches, physical educators and athletes of almost every athletic activity assume that the warming-up procedure is a mean by which athletic performance may be improved, and the chance of injury reduced; they also hold that the benefits of warming up have been attributed to an increased range of motion in the joints, increased circulation, decreased viscosity, increased body and muscle temperature and neural facilitation (24) and that warming up has an inherent psychological effect since it helps the athlete to achieve a state of mental readiness or mind set. …"
