titanium dioxide nanocrystals were synthesized by sol-gel method at room temperature. titanium isoprophoxide and absolute ethanol were used as precursors to prepare the sol. the ph of the solution was adjusted by adding nitric acid and sodium hydroxide solution. the prepared tio2 nanocrystals were annealed at 325°c, 425°c and 525°c respectively. the effect of ph on the surface morphology and st...

india is one of the largest producers of onion in the world producing over 13,920,000 metric tons. storage is a major problem which leads to spoilage, and microbes play an important role in the spoilage. in this present study, biotechnologically important strains have been isolated from the spoiled onions by using appropriate enriched media. two potential strains were isolated and a brief compa...

in this paper, the goursat problem of a general form for a linear partial differential equation is investigated with the help of the riemann function method. some results are given concerning the existence and uniqueness for the solution of the suggested problem.

In this paper, the poset $BX$ of formal balls is studied in fuzzy partial metric space $(X,p,*)$. We introduce the notion of layered complete fuzzy partial metric space and get that the poset $BX$ of formal balls is a dcpo if and only if $(X,p,*)$ is layered complete fuzzy partial metric space.

full factorial experimental design (23) for the evaluation of slurry ethylene polymerization in the presence of an industrial ticl4/mgcl2 ziegler-natta catalyst was employed. the following parameters were used as independentvariables: al/ti molar ratio, reaction temperature and hydrogen partial pressure. the total polymerization pressure was 9 bar. catalyst activity, mfi (melt flow index) and m...
