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...

it has been shown that the immunophilin ligands have the special advantage in spinal cord repair. in this study, the effects of cyclosporine a (csa) on functional recovery and histological outcome were evaluated following spinal cord injury in rats. after spinal cord hemisection in thirty six adult female sprague-dawley rats (200- 250 g), treatment groups received csa (2.5 mg/kg i.p.) at 15min ...

The brain repair field and its implications for rehabilitation after stroke continue to mature. The 4 articles that follow, including new MRI analyses for studying fiber reorganization, stratification approaches for stroke trials, synaptic-level in vivo imaging in animal models, and potential targets for neural repair therapies, provide ample evidence that our knowledge base regarding stroke re...

it is well established that the active continuous recovery is preferred to passive recovery. but the active period of this recovery is long (20-60 minutes) and the intensity is not controlled. furthermore, most severe trial exercises need short-term active recovery for better performance so that the athletes can return more rapidly to their normal state and more desirable performance. however, ...

Recovery is a part of disaster management cycle during which repair and reconstruction takes place, and individuals, groups, and communities retake what they have lost and ideally the risk of future incidents reduces. Life recovery is a subjective and multidimensional issue influenced by various factors, whereas valid measurable indicators in evaluating the recovery after di...

In this work, we synthesized a trypsin-stabilized fluorescent gold nanocluster. It was found that sulfide interacted with the nanocluster, which could result in significant fluorescence quenching. With this quenching effect, a fluorescence sulfide sensor was developed. This sensor responded linearly to sulfide in the range of 50 nM to 8 μM, and was capable of detecting sulfide as low as 5.5 nM....

The wireless world is migrating towards the era of Beyond the 3 Generation (B3G) wireless communications. A major contributor towards this convergence is reconfigurability, which provides technologies that enable terminals and network segments to dynamically adapt to the set of RATs, which are most appropriate for the conditions encountered in specific service area regions and times of the day....
