Dragana M. KLJAJIKJ,Sanja M. TRGOVCHEVIKJ,Radmila M. NIKIKJ
Journal of Special Education and Rehabilitation , 2012,
Abstract: Interpersonal communication, psychosocial and mental development of personality and its all other functions take place through the motor control. The most common neurological syndrome is a type of peripheral paresis/paralysis of plexus bracialis, which in most cases occurs at birth and significantly compromises the growth and development of the upper extremities and affects the psychomotor performance. The aim of this study was to evaluate the level of visual perception in children with lesion of plexus brachialis and the effect of the somatopedic treatment over the level of increase of the visual perception. The study sample was consisted of 60 preschool children accommodated at the Rehabilitation Centre “Dr. Miroslav Zotovi ” in Belgrade (experimental group) and examiners that followed regular checkups and had discontinuity in their therapy (control group). For the research purposes, we used The Test for Visual Perception Assessment. By analyzing the results, we concluded that in both, in the first and the second measuring there was a statistically significant correlation between the experimental and the control groups (I measuring: p<0.001, r = 0.408; II measuring: p <0.001, r = 0.593).

Journal of Special Education and Rehabilitation , 2008,
Abstract: Pupils with cerebral palsy attend elementary education accordind to a regular and special teaching plan and program. Regular school curriculum was reformed in 1992, while special plan and program has not been changed and adapted according to pupil’s needs and capacities. Music is one of the best means of expressing oneself and plays a very important role in the development of every child, the child with cerebral palsy in particular.In order to test the possibility of pupils with cerebral palsy, with and without mental retardation, to apprehend the actual program content, we have conducted research on musical achievement of children with cerebral palsy. During 2007 a research was carried out, on the sample of 27 pupils with cerebral palsy and mild mental retardation who attended classes in the school “Miodrag Matikj”, and a sample of16 students with cerebral palsy without mental retardation who attended the school “Dr. Dragan Hercog” in Belgrade.Results of the research, as well as analysis of music curriculum content, indicated that the capacities of students with cerebral palsy to carry out the curriculum tasks require special approach and methodology. Therefore, we introduced some proposals to overcome the difficulties in fulfilling music curriculum demands of those pupils. We made special emphasis on the use of computer based Assistive technology which facilitates the whole process to a large extent.

Dytrtová Radmila,Jaklová Dytrtová, J.,Jakl, M.
Journal on Efficiency and Responsibility in Education and Science , 2008,
Abstract: The activity-aided teaching using e-learning program was assessed in students’ training in Agrochemistry subject in the first year of bachelor degree study at the Faculty of Agrobiology, Food and Natural Resources of Czech University of Life Sciences Prague. The e-learning program integrated with active methods had greater efficiency in the students’ education than in classical, formal teaching. The study was achieved on two groups of students; control group (with classical teaching) and tested group (with activated teaching). Students were distributed into groups randomly and the input knowledge in chemistry followed the Gaussian distribution. Basic students’ knowledge on general chemistry was very low on the average and did not correspond with the curricular programs for secondary schools established in the Czech Republic. Activated methods of Agrochemistry teaching consisted mainly from motivation, regularly repetition connected with homework and from usage of e-learning program for self-study. The teaching effectiveness was proved by students’ score from three particular tests and by effective progression and by relative progression. The score from particular tests was related to the score from the entrance test. There were two coefficients of the students’ progression defined properly, and are applicable for a numerical or percentage value. Students from the tested group achieved statistically significantly (α = 0.05) higher scores (186 points) than students in the control group (136 points) in all three particular tests. Evaluation according to effective progression and relative progression proved the higher progress in the tested group compare to the control group. The evaluation of teaching efficiency can be proved by effective as well relative progression. The effective progression was 55 % in tested group and 26 % in control group. Higher significance of tested students’ progression was shown on relative progression; 64 % in tested students and 19 % in control students. The e-learning teaching integrated with active methods can be recommended for higher education.
Coulometric–potentiometric determination of pKA of several organic bases in propylene carbonate
LJILJANA N. JAKSIC,RADMILA M. DZUDOVIC
Journal of the Serbian Chemical Society , 2008,
Abstract: The pKA values of protonated triethylamine, pyridine and 2,2'-dipyridyl in propylene carbonate (PC) were determined by applying the coulometric––potentiometric method and a hydrogen/palladium generator anode (H2/Pd). The investigated and reference base were titrated to 50 % with protons electrogenerated from hydrogen-saturated palladium, in the presence of sodium perchlorate as the supporting electrolyte. The half-neutralization potentials E1/2(x) and E1/2(st.) of the investigated and standard base, respectively, were measured using a glass–SCE pair. The obtained pKA values were compared with those reported in the literature.
Determination of relative acidity scales for some dipolar aprotic solvents by coulometry using a hydrogen–palladium electrode
RADMILA M. DZUDOVIC,LJILJANA N. JAKSIC
Journal of the Serbian Chemical Society , 2008,
Abstract: A coulometric–potentiometric procedure for the determination of relative acidity scales of acetone, methylethyl ketone, methyl-isobutyl ketone and propylene carbonate is described. The range of the relative acidity scale of a solvent was determined from the difference between the half-neutralization potential of perchloric acid and that of tetrabutylammonium hydroxide. The perchloric acid was generated in situ from a hydrogen–palladium electrode in presence of sodium perchlorate or tetrabutylammonium perchlorate as the supporting electrolyte. The electrode pairs glass–SCE and (H2/Pd)ind–SCE were applied for the measurement of the half-neutralization potentials of the acid and base. A wider range of relative acidity scale of the solvents was obtained with the glass–SCE electrode pair and tetrabutylammonium perchlorate as the sup-porting electrolyte.
Effect of temperature on initial stage of methyl methacrylate free radical bulk polymerization
Ja?o Vladislav M.,Stoiljkovi? Dragoslav M.,Radi?evi? Radmila ?.
Hemijska Industrija , 2010, DOI: 10.2298/hemind100823055j
Abstract: Classic theory of free radical polymerization is based on two assumptions. The first is that the concentration of initiator is slightly changed and could be taken as a constant value. The second assumption is that the rate of initiation is equal to the rate of termination. Equation for the polymerization rate based on these assumptions can not successfully describe the initial stage of free radical polymerization. In order to solve this problem, three mathematical models were developed and used to verify of the mentioned assumptions. The models were fitted to experimental data and qualities of their fits were compared. Experimental data of isothermal bulk polymerization of methyl methacrylate were obtained by differential scanning calorimetry at 60, 70, 80 and 90°C with initiator concentration (AIBN) of 0.5 wt%. The best fit was shown by the model that assumes constant concentration of initiator during initial stage but takes into account that the rate of initiation is not equal to the rate of termination at the beginning.
Dispersions in porous beds
?e?erov-Sokolovi? Radmila M.,Sokolovi? Slobodan M.
Hemijska Industrija , 2004, DOI: 10.2298/hemind0402049s
Abstract: Dispersions and porous media exist either in nature or in industrial applications. They have been the subject of investigations for a long time, but the complexity of the phenomenon is the major obstacle to its better understanding. Many factors influence the interface interactions, transport, accumulation and detachment of particles in a porous matrix limiting new applications. The current state of investigations which include dispersions in the liquid continuous phase, especially emulsions, liquid/solid interface interactions in porous media and some new mathematical functions were reviewed in this paper.

Hemijska Industrija , 2003, DOI: 10.2298/hemind0308330p
Abstract: The absorption of carbon dioxide in aqueous diethanolamine solutions was carried out in a three-phase fluidized bed with inert spherical packing. The rate of absorption was calculated on the basis of measuring the concentration change in the liquid phase on-line by a conductivity probe. It was shown that the Danckwerts plot method might be successfully used to simultaneously determine the effective interfacial area and both the gas and liquid-side mass transfer coefficients. While the gas-side mass transfer coefficient is independent of the liquid flow rate, the effective interfacial area and liquid-side mass transfer coefficient increase with increasing liquid flow rate.

Abstract: The aim of this experiment was to determine the effects of broiler meal supplementation with different forms of selenium (as Na-selenite or selenized yeast) and different amounts of vitamin E on selenium and vitamin E status in broiler tissues. A total number of 240 broilers (Cobb 500) were divided in four experimental groups supplemented with Se and vitamin E for a period of 42 days: group SS+E20 - 0.3 mg/kg sodium selenite and 20 IU of vitamin E; group SY+E20 - 0.3 mg/kg selenized yeast and 20 IU of vitamin E; group SS+E100 - 0.3 mg/kg sodium selenite and 100 IU of vitamin E; group SY+E100 - 0.3 mg/kg selenized yeast and 100 IU of vitamin E. Blood plasma Se and MDA concetrations and Se dependent GSH-Px were determined on days 1, 21 and 42, where's content of Se and vitamin E in breast muscle and liver were measured on days 21 and 42 of the experiment. Highest blood plasma glutathione peroxidase (GSH-Px) activities were detected in groups SS+E20 and SS+E100. Supplementation with selenium enriched yeast did not result in a significant increase in plasma GSH-Px activity. Selenium and vitamin E concentrations in breast meat and liver were significantly higher in groups supplemented selenized yeast compared to those receiving Na-selenite. Selenium and vitamin E supplementation did not alter plasma MDA concentrations, but in tissues, selenized yeast provided a consistent, although not significant, reduction in MDA content. The increased dose of vitamin E supplemented in broiler meal was not justifiable on the basis of vitamin E tissue content and antioxidative effect.
