Dynamic changes in the present day quality of life and quality of environment are greatly influenced by the space sciences and technology. Notwithstanding the dual use of space technology the irreversible impacts on health, resources and ecology for each abuse of finite resources are alarming. Over two decades of development reviewed by UN Systems during 1970-90s reveal that Participation is the key to Sustainability at Community Levels. Space vision of a stewardship for the present generation to sustain a healthy and safe Space ship are challenging (UNCED.1992). The next two decades after Rio'92 have also provided ample break through Space Education Out Reach activities all over the globe. Few such are Bharath Jana Vigyaan Jatha Indian People Science March ( 1987), Earth Day Network(1972) and Clean Up the World(2000) Campaigns to name a few and thousands of Community Empowerment Models which have started providing the Tunnel Effect as a societal catalyst. Thus, these living through role eco literacy models enrich and add value to the Space Education and Outreach initiatives. Space Eco Literacy Model (Jagannatha, COSPAR 2012) provides one such simple Space Education Tool for empowering community for sustainable Development. UNESCO/UNEP/IEEP 1977 Tbilisi conference provided historical mandates for nations to embark on formal and informal environmental education. Objectives of Environmental Education for individuals and community as awareness, attitude, knowledge, skills and participation have lived through the Rio Earth Summit-1992.Pro- Active role of nations are vital to address and show case compliance to United Nations mandates. Public outreach activities need to be networked with various diversified activities aimed at space eco-literacy both at Individual and Community Levels. An EESS Ecological Environmental Studies by Students model developed in 1987 is one such Eco education Model which was cited as one of the 20 Best Eco Education Models.(Earth Day Network, 2000).In this presentation, genesis and process of development of EESS, 1987 and Space Eco-literacy, 2011 models in the backdrop of People Science Movement in India with over 35 years is captured from the Space Situational Awareness (SSA) point of view. A community eco literacy drive during 2000-2010 on the banks of Kukkarahally lake, Mysore, India for over 320 Sundays with 4500 man-hours 300 volunteers including all the authors provided the backdrop for Space Eco Literacy Campaign. Later the effort culminated in to a Sunday Space Eco Literacy model which was developed during April-June 2011 and are discussed.

These rare materials and archives have been carefully preserved at the Archival Section of the University of Mysore and also at other libraries in Mysore city. The present study furnishes the type of archival materials available at the University Library, Oriental Research Institute and the Karnataka State Archives, Mysore Division. Further, the study depicts the purposes of accessing archives and the use pattern of these rare archival sources on Mysore history by the research scholars, students and teachers in the discipline of Karnataka/Mysore History and allied fields. The present study also projects the extent of dependency of scholars from various professional fields, for information sources on Mysore History.

By performing a weakly non-linear stability analysis, the Nusselt number is obtained as a function of amplitude of convection which is governed by a non-autonomous Ginzburg-Landau equation derived for the stationary mode of convection. The paper succeeds in unifying the modulated Bénard-Darcy, Bénard-Rayleigh, Bénard-Brinkman and Bénard-Chandrasekhar convection problems and hence precludes the study of these individual problems in isolation. A new result that shows that asynchronous temperature modulation may be effectively used to either enhance or reduce heat transport by suitably adjusting the frequency and phase-difference of the modulated temperature is presented. © 2012 Elsevier Ltd., authorkeywords=Bénard-Darcy convection; Ginzburg-Landau amplitude equation; Nusselt number; Temperature modulation; Weakly non-linear stability analysis, keywords=Amplitude equation; Boundary temperature; Convection problem; Ginzburg-Landau equations; Modulated temperature; Phase difference; Temperature modulation; Weakly non-linear stabilities, Nonlinear equations; Nusselt number; Porous materials, Modulation, fundingdetails=University Grants Commission, references=Ahlers, G., Hohenberg, P.C., Lucke, M., Thermal convection under external modulation of the driving force, I.

This paper introduces a prototype web search results clustering engine that use the random sampling technique with medoids instead of centroids to improve clustering quality, Cluster labeling is achieved by combining intra-cluster and inter-cluster term extraction based on a variant of the information gain measure by using Modified Furthest Point First algorithm. M-FPF is compared against two other established web document clustering algorithms: Suffix Tree Clustering (STC) and Lingo, which are provided by the free open source Carrot2 Document Clustering Workbench. We measure cluster quality by considering precision , recall and relevance. Results from testing on different datasets show a considerable clustering quality. © 2013 Springer., keywords=Information retrieval; Websites, Cluster labeling; Clustering quality; Clustering system; Data sets; Document Clustering; Information gain; Intra-cluster; Medoids; Open sources; Random sampling; Suffix-trees; Term extraction; Web document clustering; Web searches, Clustering algorithms, references=Zamir, O., Etzioni, O., Web document clustering: A feasibility demonstration Proceedings of the 21st Annual International SIGIR Conference on Research and Development in Information Retrieval (1998); Hanumanthappa, M., Prakash, B.R., Mamatha, M., Improving the efficiency of document clustering and labeling using Modified FPF algorithm Proceeding of International Conference on Problem Solving and Soft Computing (2011); Geraci, F., Leoncini, M., Montangero, M., Pellegrini, M., Renda, M.E., FPF-SB: A Scalable Algorithm for Microarray Gene Expression Data Clustering (2007) LNCS, 4561, pp. 606-615. , Duffy, V.G.

The time-periodic gravity modulation, considered in this problem can be realized by vertically oscillating the porous medium. A weak non-linear stability analysis has been performed by using power series expansion in terms of the amplitude of gravity modulation, which is assumed to be small. The Nusselt number has been obtained in terms of the amplitude of convection which is governed by the non-autonomous Ginzburg-Landau equation derived for the stationary mode of convection. The effects of various parameters such as; internal Rayleigh number, amplitude and frequency of gravity modulation, thermo-mechanical anisotropies, and Vadász number on heat transport has been analyzed. It is found that the response of the convective system to the internal Rayleigh number is destabilizing. Further it is found that the heat transport can also be controlled by suitably adjusting the external parameters of the system. © 2012 Springer Science+Business Media B.V., authorkeywords=Ginzburg-Landau equation; Gravity modulation; Internal heating; Non-linear stability analysis, keywords=Anisotropic porous medium; Combined effect; Convective systems; G-jitters; Ginzburg-Landau equations; Gravity modulation; Heat transport; Internal heating; Internal heating effect; Nonautonomous; Nonlinear stability analysis; Porous medium; Power series expansions; Rayleigh number; Stationary modes; Thermal instabilities; Thermo-mechanical, Anisotropy; Nonlinear equations; Nusselt number; Porous materials, Modulation, amplitude; anisotropic medium; convective system; gravity wave; heat transfer; heating; porous medium; Rayleigh number; thermal convection; thermomechanics, references=Bhadauria, B.S., Anoj, K., Jogendra, K., Sacheti, N.C., Pallath, C., Natural convection in a rotating anisotropic porous layer with internal heat generation (2011) Transp.

Na 2CS 3 is easy to prepare and the protocol circumvents the use of strong bases and multiple steps. All the thiol compounds made were obtained as enantiopure samples and were characterized employing NMR and mass spectrometry. © 2013 Taylor & Francis Group, LLC., authorkeywords=Alkyl iodide; chiral-amino alkyl thiol; sodium trithiocarbonate, keywords=beta amino alkyl thiol derivative; carbonic acid; sodium trithiocarbonate; thiol derivative; unclassified drug, article; chemical structure; mass spectrometry; nuclear magnetic resonance; separation technique, chemicalscas=carbonic acid, 3812-32-6, 463-79-6; thiol derivative, 13940-21-1, references=Park, J.D., Kim, D.H., Cysteine derivatives as inhibitors for carboxypeptidase A: Synthesis and structure activity relationships (2002) J.
