Fluorescent in situ hybridization (FISH) with domain and group specific probes that target intracellular 16S rRNA were used to investigate microbial composition of anaerobic biofilms developed on polypropylene (hydrophobic) and glass (hydrophilic) surfaces fitted inside a Modified Robbins Device (MRD). Crushed anaerobic granular sludge was used as inoculum for biofilm development in the MRD. Th...

Abstract This work aims to investigate the role played by a model Mn-oxidizing bacterial strain and its exudates on alteration of Mn-bearing potash-lime silicate glasses representative medieval stained glass windows. Two glasses, with or without manganese, were prepared used for abiotic Pseudomonas putida inoculated dissolution experiments. Results show that presence P. slows down kinetics whil...

he article deals with the design and technological features of making jewellery using hot enameling technology by Ilgiz Fazulzyanov, one leading Russian enameller jewellers. A retrospective Master's pieces showed that complex tasks require painstaking very labour-intensive work to solve problems associated creating three-dimensional models laying stained glass enamels on precious metal bases ar...

Stalks and loricae of chrysomonads were studied by fluorescence microscopy employing Calcoflor White-Evans blue (CW-Eb) staining, and by uranyl acetate staining of dried, whole mount preparations for electron microscopy. These structures were composed of microfibrils approximately 4 nm in diameter embedded in a matrix. The organization of the loricae of Poterioochromonas malhamenesis, "Amimonas...

background: the biocompatibility of resin-modifi ed glass ionomers (rmgis) as a lining material is still under question. the present study evaluated the response of the pulp-dentin complex following application of resin-modifi ed glass-ionomer cement, calcium hydroxide and conventional glass-ionomer in deep cavities prepared in human teeth. materials and methods: in this controlled clinical tri...

Don Stookey, the father of glass–ceramics, was a pioneer in inducing and understanding internal nucleation phenomena in glass. His early work on dense opal glasses and photosensitive precipitation of gold and silver in glass led to an amazing series of inventions: Fotalite®, a photosensitive opal, chemically machined Fotoform® and Fotoceram®, and TiO2-nucleated PyroceramTM products including mi...
