1. Methyl green ("ethyl green") C. I. Number 685 was examined and found to behave identically with methyl green C. I. Number 684 (no longer available) in respect to molar extinction coefficient, effect of combination with polymerized DNA, failure to react with depolymerized DNA, and effect of pH. 2. The mass law permits the calculation of P/dye. This is found to be 13 P/dye. The same value is o...

green tea is prepared from the leaves of camellia sinensis. catechins of green tea are well known as natural antioxidants and have effective beneficial on the body. one of the most important processes in the extraction of catechins and producing green tea beverage is brewing process. the object of this study is to investigating the effect of brewing temperatures (60٫70 and 80˚c) and duration (5...

the aerobic oxidation of alcohols was efficiently completed in high conversion and selectivity using cu3/2[pmo12o40]/sio2 as catalyst under mild reaction condition. this reaction provides a new environmentally friendly rout to the conversion of alcoholic function to carbonyl groups.

the prey suitability for generalist predators is an important feature for efficient mass rearing and ipm. the green lacewing, chrysoperla carnea (stephens) is a polyphagous predator attacking several pests on various crops. this experiment was conducted under laboratory conditions at 25 ± 2 °c, 60 ± 5% r. h. and a photoperiod of 16l: 8d h. the effects of different prey species were investigated...

a simple new closed form of the green function for axisymmetric magnetostatic problemsis found analytically in cylindrical coordinates. the result is verified by applying several examples.

novel nano-catalysts (nano zno and fe doped zno (fe(0.1)zn(0.99)o) synthesized by co-precipitation method in aqueous solution as new nanocatalysts and characterized by common techniques as ftir, xrd, sem and uvd. the size of particles obtained from xrd data is 27 and 16 nanometers for zno and fresno respectively. influences of doped fe on zno catalytic properties in oxidation of benzylic alcoho...

introduction: vaginitis is an inflammatory and infectious disease in human host that involved vaginal mucosa. increase of resistance to various antibacterial agent has been very significant in three or four recent decades and this important subject reveals the use of new and natural sources such as plants with medical and antimicrobial property for eradication of these infections. therefore, th...

background: composting as a waste management technology is becoming more widespread. the purpose of this study was to assess the feasibility and to find the most effective composting process for the ratio of green waste, digested and dewatered sludge from chonibieh wastewater treatment plant in the west region of ahvaz. methods: the composting time was 23 days and the evaluated parameters in th...
