Rose productivity and physiological responses to different substrates for soil-less culture

Physiological responses and phytoremediation ability of Eastern Coneflower (Echinacea purpurea) for crude oil contaminated soil

One of the most important anthropogenic pollution types in countries with oil production is soil and water contamination by petroleum. Phytoremediation is an emerging green technology for cleaning up polluted soil. A greenhouse experiment was conducted to study the effect of oil-contaminated soil on Echinacea purpurea with four concentrations of crude oil - contaminated soil: control = 0, 0.5% ...

Physiological Responses to Different Mental Stresses

The purpose of the present study was to compare the physiological responses to different types of mental stress encountered in the workplace. Circulatory and central nervous system responses were examined in 8 healthy males by exposing them to 20-min of white noise (80 dB(A)) and 20-min of computer-based mental arithmetic tasks as models of vascular and cardiac stress, respectively. The results...

Physiological responses to different WEB page designs

Physiological indicators of arousal have long been known to be sensitive to mental events such as positive and negative emotion, changes in attention and changes in workload. It has therefore been suggested that human physiology might be of use in the evaluation of software usability. To this, there are two main approaches or paradigms: (i) comparisons of physiological readings across periods o...

Physiological Responses of Kosteletzkya virginica to Coastal Wetland Soil

Effects of salinity on growth and physiological indices of Kosteletzkya virginica seedlings were studied. Plant height, fresh weight (FW), dry weight (DW), and net photosynthetic rate (Pn) increased at 100 mM NaCl and slightly declined at 200 mM, but higher salinity induced a significant reduction. Chlorophyll content, stomatal conductance (Gs), intercellular CO2 concentration (Ci), and transpi...
