Unlike previous rules, our characterization does not require that the allocation rule be component balance. Next, we extend it to flexible networksà la Jackson (2005). Finally, we provide a comparison with other fixed network (Myerson and Position value) and flexible network (Player and Link Based) allocation rules through some examples.

Sarcoidosis is a systemic granulomatous disease of unknown origin most commonly involving the lungs. Sarcoidosis is frequently misdiagnosed due to its clinico-radiological resemblance to tuberculosis (TB). Hence, the present study was undertaken with the aim of studying the clinico-radiological profile of sarcoidosis in the Indian context.

Role of colloidal chemistry in synthesis and processing of alpha-alumina

The role of colloidal chemistry in solution synthesis and processing of alpha-alumina (alpha-Al2O... more The role of colloidal chemistry in solution synthesis and processing of alpha-alumina (alpha-Al2O3, corundum) was investigated. Experiments were designed to investigate the role of water, produced by degradation of 1,4-butanediol, on equilibrium morphology of alpha-Al2O 3 particles synthesized under glycothermal conditions. Development of platelet like morphology was promoted by low water concentrations in the solvent, and development of polyhedron morphology was promoted by high water concentrations in the solvent. A theoretical model predicting morphology for particles produced under solution conditions is proposed, with the possibility of extension of the model to any particle produced under solution conditions. A comparison was made between theoretically predicted and experimentally observed morphologies of alpha-Al2O3. Glycothermal synthesis process for preparing sub 100 nm phase pure alpha-Al2O3 nanoparticles with platelet morphology has been developed. The role of treatment temperature, seed concentration, stirring speed and solvent water content was investigated in controlling particle size and shape. Phase pure alpha-Al2O 3 nanoparticles were synthesized with specific surface area (SSA) as high as 40 m2/gm and temperatures as low as 235°C. An attempt has been made towards understanding the aggregation mechanism in alumina nanoparticles. The modeling of hydration and aggregation of alumina clusters was done using PM5 semi-empirical parameters as implemented in CAChe Worksystem. Prolonged aging of hydrated nanoparticles, even under ambient conditions, can cause bridging among the particles that can lead to neck formation resulting in aggregation of nanoparticles. Nanophase alumina powder was de-aggregated and successfully dispersed from 11 mum agglomerate/aggregate sizes down to 20 nm in 1 hr by using a chemically aided milling (CAAM) technique. Design of Experiments (DOE) was used to determine the important experimental factors to efficiently mill alumina by the CAAM process. The size of grinding media had the most significant effect in achieving average agglomeration number (AAN) less than 10, indicating well dispersed suspensions. Shaft rpm emerged as the most significant factor in controlling impurity through media wear.

Prediction of Metabolism of Drugs using Artificial Intelligence: How far have we reached?

Modeling the drug metabolism requires identification of the involved enzymes, rate and extent of metabolism, the sites of metabolism etc. There has been continuous attempts in the prediction of metabolism of drugs using artificial intelligence in effort to reduce the attrition rate of drug candidates entering to preclinical and clinical trials. Currently, there are number of predictive models available for metabolism using Support vector machines, Artificial neural networks, Bayesian classifiers etc. There is an urgent need to review their progress so far and address the existing challenges in prediction of metabolism. In this attempt, we are presenting the currently available literature models and some of the critical issues regarding prediction of drug metabolism.

Estimation of Macro Level Actinide Concentration in Process Solutions by Simple Densitometry

Coefficients of these functions were used to estimate the actinide concentrations using random-noise modulated density (±1%) and acidity data (±5%). The procedure was found feasible and for the data of Charrin et al., the typical errors were about 5%. Application of this procedure will lead to significant reduction in the active analysis of relatively pure solutions containing macro concentration of actinides and related waste generation and recovery operations..

The most common decision-making procedure in committees is by voting. In this paper we consider a generalization of voting games called bicooperative games where the strength of coalitions is taken into account. We show the existence and uniqueness of the potential function for such games. An example, where networks among players are used to illustrate the strength of coalitions, is also developed in the paper.

Our characterization is based on the standard axioms of classical cooperative games and therefore goes along the lines of the characterization of the Position value for Network games by van den Nouweland and Slikker (2012). This facilitates investigating the underlying network without any pre-condition and incorporating multilateral interactions among the players through their links. Next, we extend our allocation rule to flexible networksà la Jackson (2005). Finally, comparison with other fixed network (equal bargaining rule and Position value for network games) and flexible network (Player and Link Based) allocation rules is provided through an example.

Influence of Zeolites on Carbon Dioxide Gas Hydrate Formation

Gas hydrate formation of carbon dioxide containing gases has been proposed for separating such mixtures. In this work, effect of porous medium on gas hydrate formation kinetics hasbeen studied in detail. Silica gel of mesh size 230-400 and certain percentage of zeolite as a solid additive have been used as a medium of hydrate formation from distributed water in its pores. Zeolite 3A (beads) and zeolite 5A (beads) were used with different water saturation amount. This study is done at 274.15 K temperature and 30 bar pressure. The moles of CO2 consumed are compared for different cases. The present study is done with 100% saturation and 50% water saturation. This study indicates that there is an influence of zeolites on CO2 gas hydrates formation.

The Myerson value as a possible allo- cation rule for these games is de�ned. Axioms of paired component balance and bi-cooperative fairness are de�ned and used to characterize the Myerson value.

Hydrate Processes for CO2 Capture and Scale Up Using a New Apparatus

The presence of small amount of tetrahydrofuran (THF) substantially reduces the hydrate formation pressure from a flue (CO 2 /N 2 ) gas mixture and offers the possibility to capture CO 2 at medium pressures [1]. A conceptual flow sheet for a medium pressure hydrate process for pre-combustion capture from a fuel gas (CO 2 /H 2 ) was also developed and presented. In order to test the hydrate-based separation processes for pre and post combustion capture of CO 2 at a larger scale a new apparatus that can operate with different gas/water contact modes is set up and presented.
