As high-grade iron ores decline, the iron ore industry is shifting to mining and processing of low-grade and complex ores. As a result, large amount... E Baawuah,C Kelsey,J Addai-Mensah - International Iron Ore Conference 被引量: 0发表: 2019年 Rate-determining steps for reduction in ma...
Geometry Effect of CaCl2·6H2O at Charging and Discharging Process as Latent TES Phase Change Materials (PCMs) as thermal energy storage can store a relatively large amount of latent heat at a relatively constant temperature during the ... A Yusuf,SD 'Ulhaq,S Wonorahardjo,... - 《Journal ...
An amount representative of respirable dust is collected on a filter in a Heubach dustmeter; this may be simply weighed, or if the parent substance is a compound mixture subjected to chemical analysis. A propensity to dust for materials can thus be established....
The volume V of a mass m of water is given by V =m /ρ,where m is the mass, and ρ is the density of water. In order to warm a mass m of ice water to body temperature, the body must provide an amount Q of heat given by Q = cm∆T , where c is the specific heat of...
then this estimate can have substantially more uncertainty than the empirical estimate. Which brings us to the first problem with using a probability model: Any choice of a probability model will, in the end, turn out to be an unverifiable assumption. It amounts to nothing more than an assert...
The wound-healing process reduces the optical clarity of the cornea due to an increase in the light-scattering from the cell bodies of the corneal fibroblasts compared with that of keratocytes (7, 8, 16, 17). These results suggest that development of corneal cellular haze during wound-...
The amount of alkaline substance is not critical as long as the pH value of 7 of the reaction mixture is not exceeded. On the other hand, attempts are made to bring a maximum amount of huminate into solution to achieve as high a yield as possible. According to the invention, therefore...
The amount of benzyl benzoate which is the most abundant OC was calculated by an inter-nal standard method with an indicated amount of BP. The broken hydrogen bonds and ether bonds were responsible for the extraction of OCs from the coal .DTEs,DMDT and LCAs are essentially inso...
Studies of environmental pollutant impacts upon the olfactory system have focused primarily upon the effect of heavy metals on teleost fishes6,15,16,17. Trace amounts of heavy metals, such as mercury, cadmium, and copper, can detrimentally impact the functioning of olfactory receptor neurons (OR...
To monitor the carbon activity in a furnace atmosphere of a nitrocarburisation furnace, the degree of dissociation of the ammonia is first determined, followed by comparing a theoretical oxygen partial pressure, based on the known amounts of gas fed in, and the measured oxygen partial pressure,...
