Studies on the chloridisation of low grade ferruginous manganese ores
Hydrochlorination was attempted as a means of chemically beneficiating the low?grade manganese ores which are not amenable to upgradation by normal methods of ore dressing. The samples chosen for the present study were ... -
Studies on some fatty acid collectors in the flotation of beach sand minerals of travancore thesis
The beach sands of Travancore contain ilmenite, rutile, monazite, zircon, and garnet among others. The present investigations were undertaken not only with a view to find out the effect of some unsaturated and saturated ... -
Analytical and numerical modelling of complex multiphase flow processes in geological environments
Most geological flow and transport models describe the flow and convective-dispersive spreading of one or more components entirely dissolved in the most common geological fluid, water. However, many other processes—such ... -
Two Dimensional Numerical Modelling Of Variably Saturated Flows ?
The prediction of moisture and contaminant transport through unsaturated soil to groundwater is becoming increasingly important in the fields of hydrology, agriculture, and environmental engineering. Computer-aided simulation ... -
Quantification of uncertainties in urban precipitation extremes
Urbanization alters the hydrologic response of a catchment, resulting in increased runoff rates and volumes, and loss of infiltration and base flow. In general, quick runoff response to precipitation extremes due to short ... -
Study of the rainfall-runoff models using regression and optimization techniques
Various models representing the rainfall-runoff relationship have been in existence and are also being modified. Some of them incorporate various intermediate processes. The majority of the existing models require continuous ... -
Analytical and numerical modeling of rarefied gas flows
Most geological flow and transport models describe the flow and convective-dispersive spreading of one or more components entirely dissolved in the most common geological fluid, water. However, many other processes—such ... -
Catalytic Degradation of Polymers
The effect of various catalysts such as TiO?, cobalt Fischer–Tropsch catalyst, and AlCl? was studied on the thermal degradation of various polymers including poly(vinyl chloride) (PVC), polystyrene, and polybutadiene, both ... -
Physico-chemical problems relating to the plant required for the manfacture of acetic anhydride from acetone Part I : Thermal cracking of acetone to ketene
Various processes fo r the manufacture of a ce tic anhydride today are by oxidation of acetaldehyde, pyrolysis of a cetic Pie. acid and pyrolysis of acetone. Of these,/^acetone-cracking process seems to be the most economic ... -
Studies on polymer anchored and homogeneous catalysis : liquid phase selective oxidation of styrene to benzaldehyde by wilkinson catalyst
Wilkinson catalyst [tris(triphenylphosphine)chlororhodium(I)] finds extensive application in liquid-phase organic reactions, but its industrial applications are severely restricted by the impracticality of economically ... -
Enzymatic reactions in supercritical carbon dioxide
Lipases are enzymes that are widely used to catalyze a variety of industrially important reactions. However, lipase-catalyzed reactions are heterogeneous and are mass-transfer limited. Therefore, in most cases, the rates ... -
Selective ion exchangers crosslinked poly(4-vinyl pyridine) with transition metal ion as
Chelating resins are generally used to remove transition metal ions selectively. They are of two types: functionalized resins and templated resins. The selectivity of functionalized resins depends on the pH of the medium, ... -
Modeling and simulation of mammalian cell culture in hollow fiber bioreactors
In vitro culturing of mammalian cells is indispensable for the production of a large number of valuable products with potential medical applications. The fastidious nature of these cells, however, imposes several restrictions ... -
Studies in reaction fundamentals of cracking and aromatization of hydrocarbons
Abstract not available -
Simulations of tropical surface sinds : Seasonal cycle and International variability
Tropical climate variability is strongly influenced by coupled ocean-atmosphere interactions. The sea surface temperature (SST) influences the atmospheric heating through evaporation and convergence of moisture. The ... -
Intraseasonal oscillations and interannual variability of the Indian summer monsoon
Several modeling studies show that the predictability of the seasonal mean Indian summer monsoon is limited due to a significant fraction of the interannual variability of the seasonal mean being governed by internal chaotic ... -
Radiative effects of aerosols over land and ocean
The last two centuries have witnessed tremendous growth on all fronts (especially industrial) compared to what had occurred in the past thousands of years. This growth brought along, in addition to the awareness of safety ... -
New parameterization of atmospheric heating for simple models of relelvance to ENSO
The El Niño Southern Oscillation (ENSO) phenomenon, which is one of the strongest signals of interannual variability in the tropics, arises out of strong interactions between the tropical ocean and the atmosphere. ...
