Parallel Simulation of an Ash Melting Furnace
We determine the distribution of heat uxes of a furnace for burning ash via a simulation of a heat transfer problem. With paralleliza-tion of the problem this task can be done faster. Within the volume of the furnace, heat transfer is dominated by radiation, where heat conduction through the walls is important. Our mathematical model leads to a system of polynomials and the problem is reduced t...
متن کاملChronic and acute effects of nickel and cobalt on chlorophyll a and carotenoids of marine micro algae Nannochloropsis oculata
Algae are among the aquatic organisms that are severely exposed to increasing levels of pollutants, which are becoming a concern in marine ecosystems. Heavy metals are among the compounds for which their increase in high levels causes problems in the structure of algae communities in aquatic ecosystems. In this study, the effect of different concentrations of Nickel (1.5, 3, 4, 6, 8, 12, 15 mg/...
متن کاملEFFECT OF NICKEL AND COBALT ADDITIONS ON INFILTRATION BEHAVIOR, MICROSTRUCTURE AND HARDNESS OF W-AG COMPOSITES
In this research, infiltration behavior of W-Ag composite compacts with Nickel and Cobalt as additives has been investigated. Nickel and Cobalt were added to Tungsten powder by two distinct methods: mixing elementally and reduction of salt solution. The coated Tungsten powders were compacted under controlled pressures to make porous skeleton with 32-37 vol. % porosity. Infiltration process was ...
متن کاملa head parameter survey on mazandarani dialect and its effect(s) on learning english from ca perspective (on the basis of x-bar syntax)1
there has been a gradual shift of focus from the study of rule systems, which have increasingly been regarded as impoverished, … to the study of systems of principles, which appear to occupy a much more central position in determining the character and variety of possible human languages. there is a set of absolute universals, notions and principles existing in ug which do not vary from one ...
15 صفحه اولNickel and Cobalt Ores: Flotation
Most of the world’s nickel is extracted from the mineral pentlandite, (Ni, Fe)9S8, which frequently occurs in ores containing predominantly pyrrhotite and various non-sulRdes, some of which contain magnesium (Table 1). The nickel content in such sulRde ores is generally low (0.2}3%) and varies from place to place in the same deposit. The low nickel content of the present-day nickel sulRde ores ...
