A protein showing lower electrophoretic mobility in acidic urea polyacrylamide gels than did the usual histone H1 subfractions has been detected among the H1 histones extracted from chromatin of a transplantable hamster hepatoma, originally induced by Kirkman and Robbins. It was proved to be a true H1 histone subfraction. It differs from the remaining ones by the total chain length, amino acid ...

Potentiostatic cathodic electrodeposition of ZnTe was investigated from the viewpoint of the effect of pH on the deposits’ composition and crystallinity using citric acidic electrolytic baths, in which Zn(II) and Te(IV) species were dissolved to form ZnH2Cit þ, ZnHCit, ZnCit , Zn(Cit)2 4 and HTeO2 þ, HTeO3 , respectively (Cit: citrate) at various pH. The complex equilibrium calculation was carr...

A double chain peptide containing the sodium borohydride-reduced intermolecular cross-link, hydroxylysinohydroxynorleucine, was isolated following sequential cyanogen bromide digestion and limited alkaline hydrolysis of insoluble calf bone collagen. Amino acid composition and NH2-terminal sequence analysis indicated that the peptide was highly acidic and consisted of 19 amino acid residues incl...

Lichen symbioses were recently shown to include diverse bacterial communities. Although the biogeography of lichen species is fairly well known, the patterns of their bacterial associates are relatively poorly understood. Here we analyse the composition of Alphaproteobacteria in Cetraria aculeata, a common lichen species that occurs at high latitudes and various habitats. Using clone libraries ...

When liposomes are subjected to dehydration or freeze-thawing, vesicle fusion and/or leakage of vesicle contents can occur. The disaccharide, trehalose and the cryoprotectant, glycerol, are known to protect vesicle integrity during dehydration and freezing respectively. Here we examine their protective abilities as a function of vesicle size and lipid composition. It is shown that fatty acyl co...

Membrane separation is an emerging technology for secondary effluent (SE) recycling as alternative water source. However, SE contains metabolites which form a film on membrane surfaces, leading to decrease in hydraulic capacity. This extensive study of the effect fouling UF performance, with detailed analysis foulants composition and morphology, evaluation most effective – either physical or ch...

We tested the hypothesis that upland wetland restorations provide same quality of wetland, in terms ecosystem services and biodiversity, as natural wetlands St. Lawrence River Valley. Water (pH, alkalinity, colored dissolved organic matter, phytoplankton community composition, chlorophyll-a, fecal coliform, total phosphorus, nitrate, turbidity, specific conductivity) 17 45 restored was compared...

The Atlantic Islands of Galicia Maritime/Terrestrial National Park hosts one the largest breeding colonies yellow-legged gull (Larus michahellis) in world. In 2002, a new colony was established on Punta Muxieiro dune complex, which also harbors rare and threatened plant species habitat types community interest according to Directive 92/43/EEC. This study assesses effect this two habitats intere...

To create a more cost effective glass while preserving its safety, the composition of soda-lime silicate glass was modified. The amount of Silicon dioxide in the composition was decreased in order to lower the melting point of the glass, thus making the new glass more cost-effective due to lower energy consumption. Calcium oxide and sodium oxide concentrations were increased to raise chemical d...
