the paper will provide a summary of all lifelines performance in this strong earthquake. the paper will discuss the damage, emergency response, and recovery of electric power, telecommunication, transportation (roads and bridges), seaports, airports, water and wastewater, and their facilities. the impact as a result of the lifelines service interruption will be discussed; most important is the ...

gas injection into heavy oil reservoirs could result in high ultimate recovery of oil. experimental studies showed that an application of a combined technology of gas assisted gravity drainage (gagd) and vapor extraction (vapex) could increase final oil recovery of a candidate viscous oil reservoir. in this paper the results of laboratory investigation are presented, including pressure-volume-t...

in the present study, the effect of tail fat on recovery times in intact sheep and sheep with a ligated median sacral artery following similar anesthetic exposure with isoflurane was investigated. this study was performed using seven healthy fat-tailed iranian lori-bakhtiyari ewe lambs. the lambs were anesthetized twice at two week intervals (the experiment was performed in two stages). after m...

in this work, we developed a method which combined the processes of acid-leaching, ammonium jarosite precipitating and electro-depositing to recover copper and nickel from electroplating sludge. residual sludge from an electroplating plant located in qingdao was used for acid-leaching, and more than 95% of copper, nickel, zinc, chromium and iron were extracted from the sludge. after acid-leachi...

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, ...
