CONTINUOUS EVALUATION OF THE LITERACY AND LEARNING MEDIA OF STUDENTS WITH VISUAL IMPAIRMENT
Renata T. PANDUREVIKJ,Daniela B. Dimitrova-RADOJICHIKJ
Journal of Special Education and Rehabilitation , 2012,
Abstract: INTRODUCTION: The procedure for determining an adequate literacy and learning method among students with visual impairments consists two components: an initial choice of mode of literacy, to be conducted during the early childhood and continuing evaluation of the literacy and learning method, which is carried out over students who have already been involved in the educational process for a certain period and with whom a mediums for literacy and learning has already been determined.PURPOSE: The purpose of this research is to conduct a re-evaluation of the initial decision regarding the choice of media through which education is conducted among students with visual impairment.DISCUSSION: The speed of reading is substantially below the predicted minimum level both with students who read Braille and with students who read regular print. It should be mentioned that only 3 respondents out of 15 Braille readers were cooperative in this part of the research, so they obtained results regarding them should not be taken as reliable ones. 100% of the respondents who are educated using the Braille alphabet independently read unfamiliar formal and also familiar educational material. Among the students who use regular print, 62.5% read independently and the other 37.5% need additional instruction. 45.5% of them successfully completed their school assignments using their initially chosen medium for literacy and learning, but only 18.2% of them do it in an acceptable time period. 53.6% of respondents know how to use available resources and facilities that exist within the school, while the other 46, 4% need additional training and instructions.CONCLUSION: Continuous evaluation should be implemented consistently throughout the schooling of the child, or at least once a year, for a relevant "justification" for any change, addition or selection of another sensory channel for learning and literacy of the child, as a result of certain changes in visual functioning of the child or due to changes in the terms of their education.

Research on the Aerodynamic Resistance of Trickle Biofilter La elinio biofiltro aerodinaminio pasiprie inimo tyrimai
Alvydas Zagorskis,Renata Spie?iūt
Science – Future of Lithuania , 2011, DOI: 10.3846/mla.2011.088
Abstract: A four – section trickle biofilter was constructed for experimental research. The filter was filled with the packing material of artificial origin. The material consists of plastic balls having a large surface area. The dependence of biofilter aerodynamic resistance on supply air flow rate and the number of filter sections was determined. The aerodynamic resistance of the biofilter was measured in two cases. In the first case, the packing material of the filter was dry, whereas in the second case it was wet. The experimental research determined that an increase in the air flow rate from 0.043 m/s to 0.076 m/s causes an increase in biofilter aerodynamic resistance from 30.5 to 62.5 Pa after measuring four layers of dry packing material. In case of wet packing material, biofilter aerodynamic resistance after measuring four layers of plastic balls increases from 42.1 to 90.4 Pa.

Open Journal of Depression (OJD) , 2013, DOI: 10.4236/ojd.2013.24014
Abstract: The present study evaluated the effects of major depression on visual contrast sensitivity (CS) at low mesopic luminance (.7 cd/m2 mean luminance), a condition that has been little explored in the literature. We measured spatial visual CS in 20 male volunteers aged 20 - 30 years, including 10 healthy individuals and 10 medicated individuals with major depression, to linear sine-wave gratings of .25, 1.0, and 4.0 cycles per degree (cpd) of visual angle using the psychophysical staircase method with forced choice. The average spatial visual CS in the depressed group was approximately 1.7 lower than the average spatial visual CS in the control group. However, the post hoc test showed significant differences only at the spatial frequencies of .25 and 1.0 cpd (p < .05), which are likely processed by the magnocellular visual pathway. These results suggest that spatial visual CS to sine-wave gratings should be used to evaluate the responsiveness of the visual system in patients with major depression under conditions of low luminance.
Trifuntional Oligoetherols and Polyurethane Foams with Carbazole Ring  [PDF]

Open Journal of Organic Polymer Materials (OJOPM) , 2012, DOI: 10.4236/ojopm.2012.21001
Abstract: The method of synthesis of trifuntional oligoetherols with carbazole ring from 9-(2,3-epoxypropyl)carbazole and die- thanolamine and oxiranes like ethylene and propylene oxide was presented. Structure and some physicochemical prope- rties of the products were described. The oligoetherols were demonstrated as good substrates for synthesis of polyure- thane foams of enhanced thermal resistance. It has been found that the obtained foams are rigid at room temperature and their apparent density was 34 kg/m3- 44 kg/m3. The water uptake was low, maximum to 10.5 mass%. Dynamic thermal analysis of this foams showed that 5% mass loss starts at 200?C - 220?C, while temperature of 50% mass loss was 340?C - 370?C. Concomitantly the increase of compression strength was observed.

Abstract: Lithuanian national strategy for sustainable development is aiming to reduce air pollution per GDP unit significantly and to ensure compliance with international commitments in the air pollution sphere. Ground-level ozone (O3) is one of the most important secondary air pollutants, which is assigned to be harmful to environmental and human health and is one of the main problems of air pollution in cities. This paper aims to overview the changes in the emissions of ground level ozone precursors and their ozone forming potential as well as the achieved progress in foreseen goals. During the analysis period (1990 - 2006) emissions of ground-level ozone precursors declined twofold in Lithuania. After transitional decline intensity of ground level ozone precursors also significantly decreased due to advanced technologies, more efficient energy consumption and changes in fuel mix. However, intensity of ground-level ozone precursors in Lithuania was higher compared to the old EU member states on average, therefore much more attention should be given to special air pollution mitigation measures.

Abstract: A variant of methylation sensitive AFLP, based on the isoschizomeric combinations Acc65I/MseI and KpnI/MseI was applied to analyze, at both the sequence and methylation levels, the outcomes of regeneration from tissue culture in barley. Both sequence mutation and alteration in methylation pattern were detected. Two sets of regenerants from each of five DH donor lines were compared. One set was derived via androgenesis, and the other via somatic embryogenesis, developed from immature embryos. These comparisons delivered a quantitative assessment of the various types of somaclonal variation induced. The average level of variation was 6%, of which almost 1.7% could be accounted for by nucleotide mutation, and the remainder by changes in methylation state. The nucleotide mutation rates and the rate of epimutations were substantially similar between the andro- and embryo-derived sets of regenerants across all the donors.We have developed an AFLP based approach that is capable of describing the qualitative and quantitative characteristics of the tissue culture-induced variation. We believe that this approach will find particular value in the study of patterns of inheritance of somaclonal variation, since non-heritable variation is of little interest for the improvement of plant species which are sexually propagated. Of significant biological interest is the conclusion that the mode of regeneration has no significant effect on the balance between sequence and methylation state change induced by the tissue culture process.When plant tissue is passaged through in vitro culture, many regenerated plants appear to be no longer clonal copies of their donor genotype. Among the factors that affect this so-called tissue culture induced variation are explant genotype, explant tissue origin, medium composition, and the length of time in culture. Variation is understood to be generated via a combination of genetic and/or epigenetic changes, and although it is generally considered to b
