Wild capitalism, privatisation and employment relations in Serbia

This paper aims to examine the phenomenom of wild capitalism under post Communist transformation. Many commentators on post Communist transformation focus their attention on dysfunctional corporate governance and the deleterious consequences of liberalisation on business ethics. Poor business ethics and bad corporate governance may be a consequence of labour exploitation for comparative advantage, and the abandonment of party authority. This allowed rapacious rent-seeking by a minority well placed to benefit from the newly de-regulated regime. A by-product is a burgeoning informal economy encouraged by insider dealing of privatised state assets. State regulation, where it exists, is often ignored. Employment relations are fragmented, with state-owned enterprises retaining some form of collective regulation, while newly privatised enterprises seek to marginalise union activity

Tribology in Ballroom Dance With Energy Consumption Analysis

Tribology phenomena are obviously present and have significant importance in most of human activities, processes and actions. Ballroom Dance as a common activitie with practically importance is not enough studied and analyzed from the tribological point of view. This paper presents an attempt in this direction dealing with study of tribology aspects by analyzing a couple of Standard and Latin ballroom dances with characteristic steps and choreography. This paper shows an approximate calculation of friction forces and torques caused by some common movements and their influence on interaction in foot floor interface. Besides the approximate calculation of friction loss, authors have measured and analyze the total energy consumption by making several experiments with corresponding equipment

Separation and determination of dimethylarsenate in natural waters

A simple and efficient method for separation and determination of dimethylarsenate DMAs(V) was developed in this work. Two resins, a strong base anion exchange (SBAE) resin and iron-oxide coated hybrid (HY) resin were tested. By simple adjusting pH value of water at 7.00, DMAs(V) passed through the HY column without any changes, while all other arsenic species [inorganic arsenic and monomethylarsonate, MMAs(V)] were quantitatively bonded on HY resin. The resin capacity was calculated according to the breakthrough points in a fixed bed flow system. At pH 7.00 the HY resins bonded more than 4150 μg g-1 of As(III), 3500 μg g-1 of As(V) and 1500 μg g1 of MMAs(V). Arsenic adsorption behavior in the presence of impurities showed tolerance with the respect to potential interference of anions commonly found in natural water. DMAs(V) was determined in the effluent by ICP-MS. The detection limit was 0.03 μg L?1 and relative standard deviation (RSD) was between 1.1?7.5 %. Proposed method was established performing standard procedures: with external standard, certified reference material and the standard addition method

ESI-MS spectra of 3-cyano-4-(substituted phenyl)-6-phenyl-2(1H)-pyridinones

Twelve 3-cyano-4-(substituted phenyl)-6-phenyl-2(1H)-pyridinones were investigated by tandem mass spectrometry using positive as well as negative electrospray ionization. The influence of the electron affinity of the substituent and the steric effect on the fragmentation is discussed. Pyridinones with a substituent of low proton affinity show loss of water, HCN or benzene from the pyridinone ring in the first step of MS2 fragmentations. Oppositely, if a substituent with high proton affinity is present on the phenyl ring in the 4-position of pyridinone, the fragmentation paths are complex, depending mainly on the substituent proton acceptor ability. Elimination of neutral molecules CO, HCN, H2O, PhH (benzene) or Ph and CN radicals are fragmentation processes common for all compounds in the subsequent steps of the fragmentations

Application of analytical and CFD models of liquid fuels combustion in a fluidized bed

In Laboratory for Thermal Engineering and Energy of Institute Vinca, University of Belgrade, a 2-D CFD modeling procedure of numerical simulation of unconventional liquid fuel combustion in bubbling fluidized bed has been developed. This procedure is based on a two-fluid Euler-Euler approach modeling a fluidized bed with the determination of the velocities field of gas and particulates in two-phase, granular flows, analog to the kinetic theory of gases. This model describes in detail the unsteady motion of gas and solid phases, the formation and movement of bubbles with the combustion process in the fluidized bed, but temperature profiles calculated by the bed height differ to some extent from the experimentally obtained profiles. This discrepancy is probably due to the inability of a two-fluid CFD model to give a realistic simulation of the liquid fuel mixing in a fluidized bed. Therefore, an analytical model has been developed, where one of the basic assumptions is that the particles are mixed in the vertical direction of fluidized bed mainly by the bubble wakes. The proposed zonal type of calculating procedure is based on Davidson and Harrison two-phase model of the bubbling fluidized bed, where fluidized bed is divided into zones within which material and energy balances are set
