Polymer Chemistry REVIEW Michiya Fujiki et al. Ambidextrous circular dichroism and circularly polarised luminescence from poly(9,9-din -decylfluorene) by terpene chirality transfer PAPE R Ian Hamley et al. Self-assembly of an amyloid peptide fragment–PEG conjugate: lyotropic phase formation and influence of PEG crystallization Ambidextrous circular dichroism and circularly polarised luminescenc...
Irrigated agriculture can modify the cycling and transport of nitrogen (N), due to associated water diversions, water losses, and changes in transport flow-paths. We investigate dominant processes behind observed long-term changes in dissolved inorganic nitrogen (DIN) concentrations and loads of the extensive (465,000 km2) semi-arid Amu Darya River basin (ADRB) in Central Asia. We specifically ...
Salicylate-containing herbs have been used as analgesic and anti-inflammatory remedies from ancient times. In this work we performed a comparative HPLC study of salicylic derivatives in three natural products: Salicis cortex, Populi gemmae and Ulmariae folium. We have identified and measured by a new, easy and fast HPLC method both salicylic acid and salicin, before and after acid hydrolysis, i...
Transformatoarele de putere de înaltă tensiune reprezintă unele din cele mai costisitoare echipamente din staţiile electrice din sistemul electroenergetic. Defectele şi opririle accidentale ale acestora nu cauzează numai costuri cu reparaţiile; ele conduc şi la pierderi ecomonice datorate întreruperii alimentării consumatorilor. Testele preventive şi monitorizarea on-line sunt benefice pentru p...
The pronounced increase in the cycling and deposition of biologically reactive dissolved inorganic nitrogen (DIN) over large areas globally not only cause increased concentrations of DIN in surface waters, but it will also affect nutrient ratios in rivers, lakes and coastal areas. This review addresses the flux and fate of DIN, focusing NO3 in lakes of boreal and alpine catchments. Not only DIN...

During the past two decades coral reefs in the greater Caribbean area have been altered by phase shifts away from corals and toward macroalgae or algal turfs. This study tested the hypothesis that because the phase shift on reefs in Jamaica and southeast Florida involved frondose macroalgae, bottom-up control via nutrient enrichment must be a causal factor. The approach was multifaceted and inc...
