Studies on FRP composites with modified Epoxies : Structural and mechanical evaluation of syntactic foam sandwich composites
Epoxy syntactic foams made of glass microballoons, by virtue of their superior structural and dielectric characteristics, have proved to be efficient core materials in sandwich composites especially for microwave transparent ... -
Analysis of microwave sintering of ceramics
The use of microwaves to process ceramics has been an active area of research over the past three decades. The literature on microwave (MW) sintering is largely experimental in nature. Although models for microwave heating ... -
Steady Compressible Plane Flow Of Cohesionless Granular Materials in Hoppers and Bunkers
A continuum model based on the critical state theory of soil mechanics is used to generate stress, density, and velocity profiles, and to compute discharge rates for the flow of granular materials in wedge?shaped hoppers ... -
Model for heat transfer in a honey bee swarm
During spring, it has been observed that several thousand bees leave their hive, and settle on some object such as a tree branch. Some of the scout bees search for a suitable place where a new hive can be set up, while ... -
Thermoplastic composites of polystyrene with wood fibre based graft polymers as reinforcing agents
The results presented in this study show that manganic pyrophosphate, over a wide range of reaction conditions, is an efficient initiator for grafting styrene onto wood fibres. Selective extraction of polystyrene homopolymer ... -
Studies on oxidation of benzylidene derivatives
Perfumery compoiinds isoeugenol and isosaftole can be oxidized to their aldehydes, vanillin and heliotropin respectively. The aldehydes obtained axe very useful and commercially valuable products. Apart from their ... -
Dynamics of magnetic spheroids in time periodic magnetic fields
Magnetic nano and micro particles are used for a lot of novel applications, like mixing in inherently laminar microscale systems, bio-rheological measurements, drug delivery, and proctored surgeries. A number of studies ... -
Studies in the production of Micro organisms
The importance of the type of nitrogen in relation to the production of microorganisms of high catalytic power is emphasized. The dependence of the more appropriate and more closely related forms of nitrogen, in ... -
Testing the hypothesis of quorum sensing in vibrio fischeri : luminescence, motility, and biofilm
The individual behavior of prokaryotic organisms such as bacteria often gives rise to complexity typically associated with multicellular systems. The transition from unicellular to multicellular behavior occurs in response ... -
Systems-level modelling of hepatitis C virus Infection and treatment response
Hepatitis C Virus (HCV) infection affects approximately 130-170 million people worldwide. Interferon-based treatment, the current standard of care, fails to cure a significant fraction of patients. The cause of this treatment ... -
Studies on slurry reactors
Bubble column slurry reactors (BCSRs) are used for three phase contacting in petroleum, petrochemical, and chemical industries and in pollution control. The main objectives of the present work are: to analyse and evaluate ... -
Selective ion exchangers crosslinked poly (4-vinyl pyridine) with transition metal ion
Chelating resins are generally used to remove transition metal ions selectively. They are of two types: functionalised resins and templated resins. The selectivity in the former case is dependent on the pH of the medium, ... -
Stuides on slurry reactors
Bubble column slurry reactors (BCSRs) are used for three phase contacting in petroleum, petrochemical, and chemical industries and in pollution control. The main objectives of the present work are: to analyse and evaluate ... -
Studies in a trickle-bed reactor
Trickle bed reactors are widely used in petroleum industries and to a limited extent in chemical industries. In these reactors, a liquid reactant (or a liquid containing a reactant) trickles over a fixed bed of catalyst ... -
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 ... -
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 ... -
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 ... -
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 ...
