Optimizacija parametara reza rotornog bagera pri otkopavanju materijala sa povećanom čvrstoćom
Saša D. Bošković (2016-09-09)Otkopavanje materijala rotornim bagerom je veoma sloţen fiziĉko-mehaniĉki proces. Pokazatelji efektivnosti tog procesa zavise od velikog broja raznovrsnih ĉinilaca od kojih se posebno mogu istaći: fiziĉko-mehaniĉke karakteristike materijala koji se otkopava, reţim rada bagera i izbor tehnoloških parametara bloka, odreska i reza, geometrije vedrica i zuba itd. Poseban problem se javlja kod otkopavanja materijala povećane ĉvrstoće, što je ĉest sluĉaj na našim površinskim kopovima. Dimenzionisanje specifiĉne sile kopanja bagera prema manjim masama izuzetno ĉvrstog materijala je neracionalno i rešenje ...rotorni bager, parametri reza, otpor na kopanje, dinamika bagera, kapacitet, optimizacija, specifična potrošnja energije... Na osnovu pretpostavki teorije tanke ploĉe imamo deformacije z=0, xz=0 i yz=0 i pomeranja w=w(x,y), u=-zy=-z w/x i v=-zx =-zw/y.

Gate Road Support Deformation Forecasting Based on Multivariate Singular Spectrum Analysis and Fuzzy Time Series
Luka Crnogorac, Rade Tokalić, Zoran Gligorić, Aleksandar Milutinović, Suzana Lutovac, Aleksandar Ganić (2021)Underground mining engineers and planners in our country are faced with extremely difficult working conditions and a continuous shortage of money. Production disruptions are frequent and can sometimes last more than a week. During this time, gate road support is additionally exposed to rock stress and the result is its progressive deformation and the loss of functionality of gate roads. In such an environment, it is necessary to develop a low-cost methodology to maintain a gate road support system. ...deformacije podgrade, lasersko skeniranje, višekanalna singularna spektralna analiza, prognoza, klasterisanje fuzzy vremenskih serija... 3.126 3.026 11 Z(11) 3.537 3.344 3.258 3.124 3.031 2.930 12 Z(12) 3.371 3.219 3.146 3.079 3.017 2.936 13 Z(13) 3.072 2.939 2.890 2.815 2.778 2.730 14 Z(14) 2.723 2.662 2.634 2.606 2.587 2.552 15 Z(15) 2.305 2.271 2.241 2.239 2.219 2.209 16 Z(16) 1.860 1.853 1.844 1.839 1.820 1.812 17 Z(17) 1.245 1.241 ...

Malathion-induced inhibition of human plasma cholinesterase studied by the fluorescence spectroscopy method
The in vitro effect of technical grade malathion was assessed via the kinetic parameters of human plasma butyrylcholinesterase (BChE) using N-methylindoxyl acetate as a substrate for BChE. An inhibitor kinetics study demonstrated the existence of a biphasic inhibition curve, indicating high- and low-affinity binding sites of malathion. The IC50 values as calculated from the experimental inhibition curves were 1.33 × 10–9 and 1.48 × 10–5 M for the high- and low-affinity binding sites, respectively; Hill’s analysis gave 1.29 × ...V.
