accurate interpretation of radiographic images is dependent on viewing conditions. recently the number of radiology departments has been increased so it needs to use a workstation for reporting. the aim of this study was assess monitor performance and the effect of viewing conditions on object detection. this investigation aimed to quantify the effects of changes in box brightness and ambient l...

anionic dbs surfactant can be photodegraded in a tio2 dispersion and h2o2 solution under an hg-lamp (15 w) uv illumination or solar exposure. degradation process has been monitored through cleavage of aromatic moiety. degradation of the detergent was small when the photolysis was carried out in the absence of tio2 and h2o2 and it was negligible in the absence of light. most of the curves repres...

Isoprene emissions from the leaves of velvet bean (Mucuna pruriens L. var utilis) plants exhibited temperature response pattems that were dependent on the plant's growth temperature. Plants grown in a warm regimen (34/280C, day/night) exhibited a temperature optimum for emissions of 450C, whereas those grown in a cooler regimen (26/200C, day/night) exhibited an optimum of 40°C. Several previous...
