Employees that spend more time finding relevant data than analyzing it suffer a data discovery problem. The large volume of data in enterprises, and sometimes the lack of knowledge of the schemas aggravates this problem. Similar to how we navigate the Web today, we propose to identify semantic links that assist analysts in their discovery tasks. These links relate tables to each other, to facil...

certain gases, principally oxygen,o , and carbon dioxide, co , dissolved in water accelerate its corrosive properties. the rate of corrosion is approximately in prportion to the quantity of gas dissolved. the removal of gases from water, as practiced in steam station, is effected by mechanical and thermal treatment , by addition of chemicals, or by combinations of these processes, the most wide...

C8 Phased Out of Food Wrappers In July 2012 the U.S. FDA released a statement that manufacturers had voluntarily ceased selling agents containing the compound C8 for food-contact use the prior summer. At that time, manufacturers had predicted stocks of the agents and packaging containing them would be depleted within a year. C8, or perfluorooctanoic acid, was used to keep oil and grease from se...

In this study, a multi nanosensor was fabricated for the simultaneous detection of carbon dioxide, methane, ethanol, and ammonia gases, and its electrochemical response to various concentrations of these gases were investigated. In order to fabricate this multi nanosensor, in the first phase, the Graphene-Oxide/Polyaniline (GO/PANI) nanocomposite was synthesized. Chemical ...

in this paper, a new model based on kinetic theory of gases and longitude oscillations of metallic nanocluster on single carbon nanotube (cnt) in addition to phononvibrations of cnt on substrate is presented to describe the growth mechanism of ultra-long cnt in chemical vapor deposition (cvd).interaction between cnt and catalyst is investigated by lennard-jones potential. simulations demonstrat...

Fluorides are found in the waste discharges from process streams in a number of industries. Significant amounts of fluoride come from the following industries: semiconductor, photovoltaic, glass manufacturers, electroplating, steel and aluminum, pesticides and fertilizer. The fluoride concentration in untreated effluent can vary over a large range, and the allowable level for discharge depends ...
