Introduction to Photocatalytic Hydrogen Production
No full textNowadays, one of the major academic and technological challenges we face is the search for a sustainable source of clean energy. The need to convert solar energy into a form suitable for everyday use has triggered intense research in this field. The conversion of solar energy into chemical energy with the formation of renewable fuels through green processes has significant advantages over traditional methods. In this scenario, the photocatalytic production of H2 from pure water or from aqueous solutions containing suitable sacrificial agents represents one of the most attractive methods since it can be carried out in mild conditions (ambient pressure and temperature). In this chapter, we describe the principles of photocatalytic H2 production, the most used sacrificial agents, and photocatalytic systems together with techniques for improving photocatalyst efficiency. Even if there are numerous strategies to obtain a better efficiency of the photocatalyst, and consequently of the whole process, most of them have the purpose of decreasing the recombination of the photo-produced electrons and holes, thus increasing the number of those available on the photocatalyst surface for the reactive steps

Also giving the relation between antipodal symmetric n-sigraphs and S-antipodal symmetric n-sigraphs. Further, discussing structural characterization of S-antipodal symmetric n-sigraphs
Gestational diabetes and the incidence of diabetes in the 5 years following the index pregnancy in South Indian women
No full textThis study was carried out to examine the incidence of diabetes and the factors associated with this in a cohort of South Indian women 5 years after they were examined for gestational diabetes (GDM). Women (N=630) whose GDM status was determined (Carpenter-Coustan criteria; GDM: N=41) delivered live babies without major anomalies at the Holdsworth Memorial Hospital, Mysore. Of these, 526 women (GDM: N=35) available for follow-up after 5 years underwent a 2-h oral glucose tolerance test and detailed anthropometry. Diabetes was determined using WHO criteria, and Metabolic Syndrome using IDF criteria recommended for south Asian women. The incidence of diabetes (37% versus 2%) and Metabolic Syndrome (60% versus 26%) was considerably higher in women with previous GDM compared to non-GDM women. GDM women who developed diabetes had lower gestational insulin area-under-the-curve (P=0.05). They had larger waist-to-hip ratio, skinfolds, body mass index, and lower 30-min insulin increment at follow-up than other GDM women. In all, history of diabetes in first-degree relatives was independently associated with higher incidence of diabetes (P<0.001). Our findings suggest high diabetes and cardiovascular risks in women with previous GDM. Follow-up of these women after delivery would provide opportunities to modify adverse lifestyle factor
Iwahori-Hecke algebras acting on tensor space by -deformed letter permutations and -partition algebras
No full textLet be a commutative ring with identity and let be a free -module of rank for some . Fixing an -basis of , the symmetric group acts on by permuting and hence on tensor space for via the usual tensor product action turning and into -modules. For units in we construct an action of the corresponding Iwahori-Hecke algebra which specializes to the action of , if is taken to . The centralizing algebra of this action is called the -partition algebra . Let be a field of characteristic not dividing . We prove, that is isomorphic to the -partition algebra defined by Halverson and Thiem by different means a few years ago.21 pages, To appear in Journal of algebr
Enterprise information portal : a new paradigm in resource discovery
No full textPortals represent a wide variety of information. As organisations try to leverage more and more internal and external information and knowledge assets for competitive advantage and developing core competencies, variants of custom developed portals have burst on the scene. Enterprise Information Portals (EIP’s) have started acting as the gateway to the Implicit and Explicit knowledge assets for organizations. This paper intends to discuss the evolution, benefits and architecture of an EIP. In the end the future roadmap for EIP’s is also outlined
