Breakage parameters of some minerals and coals ground in a laboratory size ceramic mill
(NATL INST SCIENCE COMMUNICATION, 2003)The kinetics of batch dry and wet grindings of calcite, barite, quartz, lignite and anthracite from feeds of sieve size 425+300 mum has been determined using a laboratory scale ceramic ball mill. The S-l values obtained ... -
Computation of flow in a target flowmeter
(NATL INST SCIENCE COMMUNICATION, 2008)Present study determines optimum geometry for target fluidic flowmeter capable to function at small Reynolds numbers (<300). Using fluent code solver, numerical studies were carried out for gasoil measurements at various ... -
Eggplant tissue homogenate-based bioselective membrane electrode for determination of catechol
(NATL INST SCIENCE COMMUNICATION, 1999)A novel eggplant tissue homogenate-based membrane electrode with high selective response to catechol (5x10(-6)-2.5x10(-5) M concentration) has been constructed by immobilizing tissue of eggplant (Solanum melangena L.) at ... -
Floatability of barite particles with different shape and roughness
(NATL INST SCIENCE COMMUNICATION, 2007)In this article, different mill (ball, FOCI and autogenous) products of barite mineral were characterized in terms of their shape., roughness and wettability. 2D shape parameters were measured by the particle projections ... -
Force constant calculations for Hg[CO(CO)(4)](2) frorn the CO-factored force field
(NATL INST SCIENCE COMMUNICATION, 2007)An analytical approach to solve the CO-factored force fields of Hg[Co(CO)(4)](2) belonging to D-3d Point group is described here. The approach leads to relationships which allow direct calculation of carbonyl stretching ... -
Liver and colon pro- and anti-oxidant enzyme activities in rats after long-term ethylnitrosourea exposure
(NATL INST SCIENCE COMMUNICATION, 2003)Liver and colon pro- and anti-oxidant enzyme activities were investigated in rats treated with ethyl nitrosourea (ENU) (i.p.) (4 mg/kg body wt) for 6 months. The pro-oxidant enzymes (NADPH cytochrome c reductase, NADH ... -
A model for extended bench casting in dipping coal seam
(NATL INST SCIENCE COMMUNICATION, 2007)This paper deals with extended bench casting with draglines in surface coalmines. A computer model, developed for panel design, covers three fundamental operating modes: i) level casting for flat-lying coal seam; ii) ... -
A new approach to predicting the carbonyl stretching frequencies of Co-2(CO)(8) with D-3d symmetry
(NATL INST SCIENCE COMMUNICATION, 2007)This paper describes a method for determining C-O stretching frequencies of dicobalt octacarbonyl belonging to D-3d point group. The method is based on the variation of fundamental C-O stretching frequencies and C-O ... -
Performance of different oils in oil agglomeration of Zonguldak coal
(NATL INST SCIENCE COMMUNICATION, 2003)In this study, comparison of performance of different oils, in the cleaning of Zonguldak coal, by oil agglomeration was investigated. The feed coal was agglomerated with both classic oils (kerosene, diesel and fuel) used ... -
Relationship between the breakage and wetting characteristics of lignite
(NATL INST SCIENCE COMMUNICATION, 2002)This paper reports the findings of an investigation of the breakage values of lignite to relate the wettability properties. The breakage values, obtained from grinding, are the specific rates of breakage (S-i) and the gamma ... -
Spoil room utilization in dragline stripping
(NATL INST SCIENCE COMMUNICATION, 2009)This paper deals with spoil roam utilization by two different spoil placement techniques. A three-dimensional computer-aided design approach for generating conical and curvilinear spoil piles are developed. Curvilinear ... -
Temperature distribution study in resistance spot welding
(NATL INST SCIENCE COMMUNICATION, 2009)This paper presents effect of sheet thickness and current density on cooling speed and temperature distribution in resistance spot welding. Thicker sheets have higher temperatures in weld zones. Temperatures are higher in ...
