Conservation of resources in the pulp and paper industry derived from cleaner production approach
(Resources Conservation and Recycling, 2011)
This paper analyses the utilization of water and recycled fiber from waste paper for the production in one Serbian cardboard mill. Water and fiber consumption, wastewater generation and its characteristics, as well as ...
Experimental determination and modeling of densities and refractive indices of the binary systems alcohol plus dicyclohexylamine at T = (288.15-323.15)K
(Elsevier, Amsterdam, 2011)
The experimental density rho and refractive index n(D) data have been determined for the systems of dicyclohexilamine with 1-propanol, or 1-butanol, or 2-butanol, or 1-pentanol, in the temperature range (288.15, 293.15, ...
Comparison of structural, textural and thermal characteristics of pure and acid treated bentonites from Aleksinac and Petrovac (Serbia)
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
Bentonite samples collected from vicinity of Petrovac and Aleksinac were treated with different sulfuric acid molarities. Acid attack dissolved the octahedral sheets by interlayer and edge attack. The effects of the H2SO4 ...
High-temperature deformation behaviour of Ti3Al-11Nb intermetallic
(Carl Hanser Verlag, Munich, 2011)
A mechanism of high-temperature plasticity has been studied in terms of stress exponent and activation energy for deformation. A Ti3Al-based intermetallic was processed by hot-rolling in the two-phase field to accomplish ...
Immobilization of lipase from Candida rugosa on Sepabeads(A (R)): the effect of lipase oxidation by periodates
(Springer, New York, 2011)
The objective of this paper was the investigation of a suitable Sepabeads(A (R)) support and method for immobilization of lipase from Candida rugosa. Three different supports were used, two with amino groups, (Sepabeads(A ...
Experimental Determination of Densities and Refractive Indices of the Ternary Mixture 2-Methyl-2-propanol + Cyclohexylamine plus n-Heptane at T = (303.15 to 323.15) K
(Amer Chemical Soc, Washington, 2011)
The experimental data of the tertiary 2-methyl-2-propanol + cyclohexylamine + n-heptane (densities rho and refractive indices nD data) and three binary systems: 2-methy1-2-propanol + cyclohexylamine (n(D) data). ...
Total polyphenols and antioxidative activity of water extracts of spent coffee

Inhibition of Microbial Growth by Silver-Starch Nanocomposite Thin Films
(Vsp Bv, Leiden, 2011)
A sago starch biopolymer with embedded silver nanoparticles has been studied as a material for the prevention of microbial growth. Approximately 8 nm in size, silver nanoparticles have been synthesized by reduction of the ...
Reactivation of a thermostable lipase by solid phase unfolding/refolding Effect of cysteine residues on refolding efficiency
(Elsevier Science Inc, New York, 2011)
Lipase from Geobacillus thermocatenulatus (BTL2) was immobilized in two different matrixes. In one derivative, the enzyme was immobilized on agarose activated with cyanogen bromide (CNBr-BTL2) via its most reactive superficial ...
Solidification of High Chromium White Cast Iron Alloyed with Vanadium
(Japan Inst Metals, Sendai, 2011)
Experimental results indicate that vanadium affects the solidification process in high chromium iron. Vanadium is distributed between eutectic M7C3 carbide and the matrix, but its content in carbide is considerably higher. ...
