nano-sized γ-al2o3 was synthesized successfully by a simple method using al2(so4)3·18h2o as aluminium source and in the presence of polyethylene glycol (peg 2000). ftir spectroscopy, x-ray diffraction (xrd), scanning electron microscope (sem) and transmission electron microscope (tem) were used to characterize the structure and morphology of synthesized powder. the results showed that peg playe...

A series of novel water-soluble beta-carbolines bearing a flexible amino side chain was designed, synthesized and evaluated as potent cytotoxic and DNA intercatalating agents. The N(9)-arylated alkyl substituted beta-carbolines represented the most interesting cytotoxic activities. The results suggested that (1) the N(9)-arylated alkyl substituents of beta-carboline nucleus played a very import...

effects of nitrogen fertilization timing close to the beginning of short-day period and white mulch on flowering and yield components have been studied in ‘paros’ and ‘queen elisa’ strawberry cultivars. split plot experiment in a randomized complete block design with eight treatments (two mulch treatments × n fertilization during four different times from last week of august to third week of se...

17-11 ABSTRACT The breeding program has been conducted to improve the production and quality of napiergrass by crossing with related species or intraspecies. CV. TLG2 with high yields and water soluble carbohydrates have been selected and released. It produced 20% more forage yields and water soluble carbohydrates than cultivar, CV. A146 and persisted well at least for five years. Good silage w...

Information systems development needs to be taught using an expeChris Cope riential approach. This is difficult when introductory classes are large and the stuPat Horan dents have no knowledge of the complex social and business environments in which Department of Information Technology information systems are developed. This paper presents a teaching approach called aLa Trobe University, BendiO...

Accumulation of foliar carbohydrates is one of the most pronounced and universal changes observed in the leaves of C3 plants grown at elevated CO2 concentration (e[CO2]). Carbohydrates are both the product of photosynthetic cells and the substrate for sink metabolism. However, carbohydrates are not just substrates; and the role of carbohydrates in regulation of the expression of many plant gene...

introduction lentil (lens culinaris medik.) is a good source of protein, carbohydrates as well as minerals, vitamins and unsaturated fatty acids as such it plays an important role in the human diet and cultivated worldwide. water shortage is one of the most important abiotic factors that can limit morphological, physiological, yield, and plant distribution. legumes such as lentil are highly sen...
