Micromechanical analysis of mechanical heterogeneity effect on the ductile tearing of weldments
(Elsevier Sci Ltd, Oxford, 2012)
The objective of this study is determination of the effect of mechanical heterogeneity on ductile crack initiation and propagation in weldments using micromechanical approach. Welded single-edge notched bend (SENB) specimens ...
Micromechanical modelling of ductile fracture - local approach
(Savez inženjera metalurgije Srbije, Beograd, 2019)
Micromechanical modelling of ductile fracture by using the local approach has been presented as the review of previously obtained results for welded joints made of low alloyed high strength steel. Experimental work was ...

Sugar beet pulp and molasses as a solid state fermentation media for cellulase production by Paenibacillus chitinolyticus CKS1
(Bor : Technical Faculty, 2015)
Sugar beet pulp (SBP) and molasses, by-products from sugar industry were used as a substrate for cellulase production in this study. Solid state fermentation (SSF) was performed by a natural isolate Paenibacillus chitinolyticus ...
Cellulolytic potencial of a strain Paenibacillus sp. isolated from soil
(Serbian Chemical Society, 2013)
Cellulases are the enzymes which cause hydrolyzis of the polysaccharide cellulose into
smaller sugar units. Bacterial cellulases possess more advantages when compared to the
cellulases from other sources. The gram positive, ...
