This paper revisits the cultural stereotype of a sharp binary division between “summer” and “winter” temporalities in an island town Croatia (Hvar). It highlights existence parallel competing that generate heterogeneous social individual rhythms. The overarching rhythm summer tourism, which divides year into (roughly May October) November April), conceals other temporalities, both sense how loc...

Summarization of electronic discussion fora is a unique challenge; techniques that work startlingly well on monolithic documents tend to fare poorly in this informal setting. Additionally, conventional techniques ignore much of the structures that have the potential to serve as valuable features in the summarization task. We present several novel examples of such features, including the catalys...

Abstract A series of aryl sulfonic acids were tested as catalysts for acid hydrolysis occurring at the surface poly(ethylene) terephthalate (PET) particles. Specifically, p‐toluenesulfonic monohydrate (PTSA), 2‐naphthalenesulfonic (2‐NSA), and 1,5‐naphthalenedisulfonic tetrahydrate (1,5‐NDSA) chosen to provide active groups varying hydrophobic functionality. The effect catalyst concentration re...

Pesticide contamination of natural waters is posing serious threats to water supplies in many parts of the world. Heterogenous photocatalytic Oxidation with TiO2 photocatalyst is emerging as an attractive technique for pesticide removal. Studies on Monocrotophos (MCP) a widely used pesticide in India, in an annular slurry photoreactor, revealed that the degradation rate is significantly affecte...

A heterogenous catalyst in the form of Au nanoparticles (Au NPs) immobilized porous manganese oxide (Mn5O8) microspheres was synthesized. The sol-gel templating method used for synthesis Mn5O8 microspheres. showed good performance when compared with similar catalysts oxidation benzyl alcohol. (Au@Mn5O8) obtained by immobilization NPs on performed 99.4% alcohol conversion and 100 % benzaldehyde ...

NOVEL HETEROGENOUS AND MAGNETICALY SEPARABLE CATALYSTS FOR SELECTIVE AND ENANTIOSELECTIVE ORGANIC TRANSFORMATIONS A brief description of the chapters in the thesis is outlined below: Chapter 1 Chapter 2 Chapter 5 Chapter 3 Chapter 4 Section B Section A THESIS CHAPTER-I, describes the various catalysts/process options available for an industrial chemist to effect different organic transformation...

Abstract Depletion of fossil fuels resources has triggered more research on finding potential alternative sources that are sustainable such as biomass waste. However, deconstruction the complex waste into desired products is too challenging and usually require a strong catalyst with great hydrolysing property. Common acids sulphuric acid, hydrochloric acid nitric were most studies for conversio...
