The effects of ring width, stem position, and stand density on the relationship between foliage biomass and sapwood area in Scots pine ( Pinus sylvestris ) The effects of the average ring width of sapwood, bole length, and stand density on the relationship between foliage biomass and sapwood...
The relationship between xylem embolism and eco-physiology indices (i.e. photosynthetic available radiation, temperature, relative humidity, photosynthetic rate, transpiration rate, stomatal conductance and water use efficiency) in eight tree species was investigated in situ. The species studied, Robinia ...
MECHANISMS AND PATHOPHYSIOLOGY OF OBESITY- RELATED HYPERTENSION The association of obesity and hypertension has been recognized since the beginning of the twentieth century when blood pressure was first measured in populations, and this relationship between body weight and blood pressure was demonstrated ...
To investigate the correlation between socioeconomic status (SES) and the incidence of hypertension among adults aged 18 or above in southwest China. A multistage proportional stratified cluster sampling method was employed to recruited 9280 adult reside
Also, a questioner is designed and then, completed by managers of Iranian ENGOs. It is found that there is too little communication between Iranian ENGOs and governmental agencies. ENGOs don't discuss various environmental issues with government as advocators. Finally, the principles governing ...
Recent investigations have examined the effects of a wide range of parameters (injection pressure, orifice diameter, and ambient gas temperature, density and oxygen concentration) on lift-off length under quiescent diesel conditions. Many of the experimental trends in lift-off length were in agreement...
