Impact of choice of stabilized hysteresis loop on the end result of investigation of high-strength low-alloy (hsla) steel on low cycle fatigue
(Croatian Metallurgical Soc, Zagreb, 2014)
High strength low-alloy steel under low cycle fatigue at a certain level of strain controlled achieve stabilized condition. During the fatigue loading stabilized hysteresis loop is determined, which typical cycle of ...
Solvent and structural effects in tautomeric 3-cyano-4-(substituted phenyl)-6-phenyl-2(1H)-pyridones: experimental and quantum chemical study
(Springer/Plenum Publishers, New York, 2014)
The tautomeric equilibria between 2-pyridone and 2-hydroxypyridine forms of methoxy, chloro, and nitro derivatives of 3-cyano-4-(2-, 3-, and 4-substituted phenyl)-6-phenyl-2(1H)-pyridones were evaluated from UV/Vis spectral ...
ZnO-modified cellulose fiber sheets for antibody immobilization
(Elsevier Sci Ltd, Oxford, 2014)
Cellulose fiber sheets impregnated with saccharide capped-ZnO nanoparticles were used as bioactive materials for antibody immobilization. First, ZnO nanoparticles were synthesized in the presence of glucose (monosaccharide), ...
Hydrodynamic modeling of downward gas-solid flow. Part II: Co-current flow
(Elsevier, Amsterdam, 2014)
The one-dimensional model of accelerating turbulent downward co-current gas-solid flow of coarse particles was formulated and experimentally verified by measuring the pressure distribution along the transport tube. The ...
The role of knowledge economy in solving unemployment problem / Uloga ekonomije znanja u rešavanju problema nezaposlenosti
(Društvo ekonomista Beograda, Beograd, 2014)
Knowledge economy means development based on production, distribution and usage of knowledge. Knowledge is main economic source and starter of modern economies. Knowledge in innovations and new technologies enable the ...
On the role of aniline oligomers on the corrosion protection of mild steel
(Elsevier Science Sa, Lausanne, 2014)
Corrosion of the mild steel electrode with electrochemically formed aniline oligomers coating in 3% NaCl has been investigated by the means of electrochemical techniques and UV-vis spectroscopy. It has been shown that ...
Two-Stage Fermentation for 2-Ketogluconic Acid Production by Klebsiella pneumoniae
(Korean Soc Microbiology & Biotechnology, Seoul, 2014)
2-Ketogluconic acid production by Klebsiella pneumoniae is a pH-dependent process, strictly proceeding under acidic conditions. Unfortunately, cell growth is inhibited by acidic conditions, resulting in low productivity ...
Low cycle fatigue of weldments produced of a high strength low alloyed steel
(Elsevier Science Bv, Amsterdam, 2014)
A quenched and tempered high strength low alloy steel NIONIKRAL 70 for producing welded pressure vessels, where high resistance to fatigue crack propagation and high tolerance of damage are of high importance, has been ...
Spectroscopic and quantum mechanical investigation of N,N '-bisarylmalonamides: solvent and structural effects
(Springer, New York, 2014)
The UV absorption spectra of ten N,N'-bisarylmalonamides have been recorded in the range 200-400 nm in a set of selected solvents. The solute-solvent interactions have been analyzed on the basis of the linear solvation ...
Design of Multi-pressure Organic Rankine Cycles for Waste Heat Recovery in Site Utility Systems
(Elsevier Science Bv, Amsterdam, 2014)
This work addresses the design of Organic Rankine Cycle (ORC) processes used for power generation from low-grade heat available in site utility systems. The Exergy Composite Curves approach is used within a systemic ...
