Blue light and ultra-violet (UV) have been shown to influence plant growth, morphology, quality. In this study, we investigated the effects of pre-harvest supplemental lighting using UV-A blue (UV-A/Blue) red (RB) on growth nutritional quality lettuce grown hydroponically in two greenhouse experiments. The RB spectrum was applied for days or nights, while UV-A/Blue four nights. All treatments h...

Consider two adolescents: Person One and Person Two. Person One has never used substances and exhibits relatively few behavioral (conduct) problems. On the other hand, Person Two uses substances frequently and more commonly exhibits poor conduct. If you were to guess, which of the individuals would you expect to have lower overall judgment and self-regulation? If you answered Person Two, your i...

sawdust which is the main waste from wood industry has been used as a raw material forremoval of brilliant cresyl blue toxic dye. the effects of various parameters such as ph,electrolyte concentration, adsorbent dose, contact time and agitation rate were studied for theremoval of the dye in a concentration of 50 mg l-1. the optimum condition for the studiedparameters was applied for various con...

a simple, rapid and sensitive spectrophotometric method has been proposed for the determinationof vanadium (iv). the method is based on the catalytic effect of v (iv) on the oxidation of alkali blue bypotassium bromate at ph 4. the rate of decrease in the absorbance of alkali blue (at 572 nm) wasproportional to the concentration of v (iv) in the range of 100-6000 ng ml-1. the detection limit wa...

a catalytic-kinetic method for the determination of selenium is proposed. alizarin navy blue is reduced by sodium sulfide to from a colorless product. the reaction is accelerated by trace amounts of se (iv), and can be followed by measuring the decrease in absorbance of the dye at 620nm and 30 °c by the fixed time method. selenium can be determined in the range of 0.004 — 0.12 1.1g.m1-1 . ...

In this study, montmorillonite clay was used as the adsorbent for the removal of Aniline Blue dye, from aqueous solution by the batch adsorption technique under different conditions. The maximum removal of aniline blue dye for initial dye concentration 20 mg/L was more than 95% at optimum conditions (pH=4.5, contact time=30 min, and adsorbent dosage=2 g/L). The data of this study were fitted wi...

In September 2000 AIRSAR-TOPSAR data were acquired over the environment and cultural landscape of the World Heritage site of Angkor in Cambodia as part of a collaborative research project between APSARA (Royal Cambodian Government Agency responsible for Angkor), EFEO (Ecole Francaise d’Eextreme Orient) and the University of Sydney. Termed the Greater Angkor Project, additional support from the ...

Climate-related declines in lake area have been identified across circumpolar regions and have been characterized by substantial spatial heterogeneity. An improved understanding of the mechanisms underlying lake area trends is necessary to predict where change is most likely to occur and to identify implications for high latitude reservoirs of carbon. Here, using a population of ca. 2300 lakes ...

For exploring the impact of health education for schistosomiasis control in a heavy endemic area of Poyang Lake region, China, the residents residing in the heavy endemic area were divide into three kinds of target population: pupils, adult women and adult men, and then targeted health education was implemented respectively among the three kinds of population after a baseline survey. The result...
