Comparing the impact of different cameras and image resolution to recognize the data matrix codes
Authors: Karrach Ladislav , Pivarčiová Elena , Nikitin Yury Rafailovich 
Published: September 2018

Abstract
Data matrix codes are two-dimensional (2D) matrix bar codes, which are the descendants of the well known 1D bar codes. However, compared to 1D bar codes, they allow to store much more information in the same area. Comparing data matrix codes with QR codes, for example, we find them much more effective in marking small objects or in the case that you have only a very small area for placing a code in. Their capacity and ability of decoding also a code that is partly damaged make them an appropriate solution for industrial applications. In the following paper we compare the impact of various cameras on the detection and decoding of data matrix codes in real scene images. The location of the code is based on the fact that typical bordering of a data matrix code forms a region of connected points which create “L”, the so-called finder pattern, and the parallel dotting, the so-called timing pattern. In the first step, we try to locate the finder pattern using adaptive thresholding and connecting neighbouring points to continuous regions. Then we search for the regions where 3 outer boundary points form a isosceles right triangle that could represent the finder pattern. In the second step, we have to verify the timing pattern. We look for an even number of crossings between the background and foreground. Experimental results show that the algorithm we have proposed provides better results than competitive solutions.

Published: September 2018

Abstract
Studies have established that the use of technology in early childhood care and education (ECCE) settings positively contributes to children’s development. However, this position has generated conflicting views as individual circumstances largely depend on where a child is born and raised. In this study, adoption of Information and Communication Technology (ICT) in ECCE in the Nigerian context is examined, with a view to deciphering practical implications of ICT as social innovation in learning and its influence on socio-cultural values in childhood education. To achieve this aim, the following research question was generated: What and how can we describe the impact and practical implications of ICT on Nigerian children’s ways of life, and what values does ICT contribute towards socio-cultural aspect of ECCE education in Nigeria? The paper utilised data collected through an interpretive qualitative study, underpinned by social practice and innovation diffusion theories. Data were generated through interviews and classroom observations. The findings suggest tensions between social innovations and socio-cultural implications of ICT usage. It was observed that ICT usage in Nigerian childhood education is situated within tripartite classification; One, as a veritable tool for achieving innovative and creative thinking in children. Two, as an effective instrument of disseminating globalised ideas and three, as distortions to socio-cultural values that are embedded in culturally-sensitive children learning and development. In conclusion, it was suggested that while the use of ICT should remain a veritable instrument for learning in children’s formative periods, its usage should be monitored for values’ security in Nigeria.
From Audit-Phobia to Shared Governance Philosophies: Librarians Meet Auditors at the European University Institute
Authors: Baltos Georgios , Alpigiano Carlotta 
Published: September 2018

Abstract
Libraries are rightfully recognized as the heart of academic institutions. However, they are not standalone, but interconnected with all other players within the same organisational universe: academia, administration, stakeholders, internal and external competitors and co-operators. Internal auditors’ role is to promote quality standards along with a “continuous improvement” culture that includes efficiency, accountability and performance excellence at institutional level. Librarians have a long tradition of performance indicators’ collection and evaluation. The crossroad where librarians and auditors meet each other is represented by an integrated methodology which links objectives, risks, performances and controls, harmonising them within the institutional context. The case of such a collaboration at European University Institute (EUI) is a noteworthy example.
Multilingualism in Linguistic Landscape of Prishtina (Kosovo)
Authors: Prishtina Shkumbin Munishi 
Published: September 2018

Abstract
Language relations as manifestations of the phenomenon of multilingualism are also expressed in the area of the so-called linguistic landscape. Undoubtedly, the linguistic landscape not only reflects the use of languages in public space but at the same time reveals the depth of public perception of different languages, depending on their function and prestige. In this paper, I will treat Albanian, English and Serbian rapports through their coverage in the Pristina linguistic landscape, focusing on the use of these languages in advertising space in the city of Prishtina and in other tables that perform semiotic functions of indexes in this city. Likewise, within the reflection of the status planning of languages in Prishtina linguistic landscape, the use of Serbian in the official tables will be treated. This case study will also reflect the features of language policy and the impact of the globalization phenomenon in different languages. The results presented in this paper will reflect on the field research within a certain time span. The research has shown that in the Pristina linguistic landscape, in addition to the Albanian language, English has a dense use, while the use of Serbian is mostly limited to official charts i.e. names of the streets of the city and is not found in private advertisements tables.

AbstractThe work is devoted to study of seed oil composition of amaranth varieties: Kharkov, Lera, Andijan and Helios, acclimatized in Uzbekistan. We demonstrated the possibility of using reversed-phase HPLC using a refractometric detector, which allows simultaneous determination of squalene and triacylglycerides in plant seeds and determining the authenticity of amaranth oils. Established seed oiliness ranged from 6.39 to 7.81 % of the initial mass. Amaranth oil samples contained quite large amount of unsaturated fatty acids 72.72 – 73.28 %, 1.17 % of which is omega-3-alpha-linolenic acid. The squalene content in the seeds ranged from 0.35 % to 0.55 %. It was established that the squalene content in oils obtained by extraction is greater than the one obtained by cold pressing. In the triacylglyceride composition of the investigated cold-pressed and extracted oils, no significant differences were found.

Abstract
Quinoa (Chenopodium quinoa Willd.) has been nutritionally highlighted when compared to other grains. In recent years the research on this pseudocereal has increased. In this work, six quinoa samples were studied: three from Peru, one from Brazil and two commercial samples. The samples were physically and physicochemically characterized, including macro- and micronutrient analysis, phenolic compounds content and antioxidant activity. Black, red and white samples showed as main difference the size, weight, ashes and dietary fibre content. Black samples were the smallest and lightest and had the lowest starch content but presented the highest levels of ashes and dietary fibre. The protein content (16.9 %) in the white Brazilian variety was higher than the others. Red and black samples had the highest levels of most minerals analysed. The antioxidant capacity measured by the DPPH method was higher for black and red samples in comparison with the white ones. However, the white Brazilian variety showed a significantly higher antioxidant capacity measured by the ABTS assay. With regard to the phenolic content, a difference was found between the samples which ranged from 55.5 to 95.5 g GAE 100 g−1. The colour of the grain was found as not related to a higher content of phenolic compounds. Because their compositions are generally similar to light-coloured grains, and in some parameters such as dietary fibre and content of some micronutrients are superior, the grains of dark-coloured quinoa varieties (RPP, BCP) would have to be explored to develop foods that take advantage of this colour diversity.

Published: September 2018

Abstract
Safflower is one of the most important oilseed crops in semi-arid regions. The soil of semi-arid areas often encounters micronutrient deficiencies. However, nutrients imbalance seems to affect the quantitative and qualitative aspects of the oil as well as plant growth. Current experiment was carried out to evaluate the impact of different application practices (soil application and foliar spray) of micronutrients (Fe, Zn, Mn) on oil content, fatty acid profile and yield components of safflower under full and limited irrigations. Results showed that all of investigated traits were significantly affected by fertilizer treatment and irrigation system. The highest seed protein content was recorded for plants grown by soil application of Zn under limited irrigation condition. The highest oil content was achieved by soil application of Zn under full irrigation condition. The water deficit significantly reduced some qualitative characteristics such as oleic acid, palmitic aid, stearic acid, linoleic acid, iodine value and saponification value. The highest head number per plant, seed number per head and seed yield recorded in plants grown by soil application of Fe and Zn under full irrigation condition. Although the use of micronutrients improved qualitative characteristics in comparison with control, the best qualitative characteristics were achieved with the soil application of Zn and Fe. The elimination of micronutrient deficiencies and the balanced supply of nutrients through soil along with optimal and timely irrigation can significantly increase the efficiency of safflower production systems and improve the quality of the oil.

Authors: Hroboňová Katarína , Sádecká Jana , Čižmárik Jozef 
Published: September 2018

AbstractDicoumarol is a mycotoxin, that acts as a blood anticoagulant, is formed during the microbial action of molds and fungi in spoiled hay or silage containing high-coumarin plant. A HPLC-DAD method for determination of coumarins, including dicoumarol, coumarin, and 4-hydroxycoumarin was developed. Methanol and acetic acid were used as mobile phase with gradient elution. The simultaneous separation was performed using C18 type of stationary phase. The recoveries were 88.6 – 92.6 %, 91.8 – 95.0 %, and 89.7 – 94.1 % (evaluated for three concentration levels) for dicoumarol, coumarin, and 4-hydroxycoumarin respectively. The parameters of system suitability (repeatability of retention times and peak areas) were determined for evaluation of the method. The method showed a good linearity in the concentration range 0.7 – 100 μg.mL−1for dicoumarol, 0.05 – 100 μg.mL−1for coumarin and 4-hydroxycoumarin with correlation coefficients higher than 0.9885. Extracts of sweet clover herb, hay, and spoiled hay were subjected to HPLC-DAD analysis. The most abundant compound in sweet clover herb and hay extracts was coumarin. In spoiled sweet clover hay extract the 4-hydroxycoumarin was detected in addition. The formation of 4-hydroxycoumarin was also observed in the synchronous fluorescence spectra recorded at the wavelength difference of 90 nm (difference between emission and excitation wavelength).

Abstract

Introduction
. Moldova is the European country with the highest incidence of hepatocellular carcinoma (HCC) in both sexes. There is, however, no data comprehensively describing the presentation and the risk factors of HCC in the country. We decided to analyze cases of HCC recently received in a tertiary healthcare Institution from Chisinau, the Moldovian capital.

Methods
. A series of 148 primary liver tumors including 139 cases of HCC were retrospectively analyzed for demographic features, serological and biochemical data, and clinical presentation.

Results
. The mean age of patients was 59 ± 10 years (range: 19-66) with a M:F sex ratio of 1.9. Tumors appeared on full-blown liver cirrhosis in 83% of cases and were composed of multiple nodules at diagnosis in 36% of patients. Serum Alpha-fetoprotein was exceeding 10ng/mL in 76% of cases. Liver tumor and hepatitis were co-discovered in 34% of cases. More than 81% of hepatocellular carcinomas were associated with at least one hepatitis virus. Carriers of anti-hepatitis C virus were predominating (55% of cases) over patients seropositive for hepatitis B virus surface antigen (36%). Half of the latter were also infected with hepatitis Delta virus. In total, dual or triple infections were present in 24% and 7% of cases.

Conclusions
. The burden of infections with hepatitis viruses is particularly important in Moldova and corresponds to a situation commonly observed in countries of the Southern hemisphere. A pro-active policy of screening for persistent liver infection targeting population at risk of HCC (> 50 years) and coupled with the distribution of antivirals in positive cases should be rapidly implemented in Moldova to reduce incidence or primary liver cancer.

Published: September 2018

AbstractThe objective of our study was to determine the effect of 5% of CO2atmosphere and time of sample dilution on results of in vitroanalysis of stallion semen. Frozen-thawed semen from 14 stallions was incubated either in incubator or in a water bath, diluted prior to analysis or immediatelly after thawing. The following qualitative parameters were assessed after thawing (T0) and after 30 min (T30): motility in 3 sperm subpopulations (slow, medium, fast) defined by cluster analysis of parameters obtained by Computer Assisted Sperm Analysis, viability, acrosome and mitochondrial integrity. The slow subpopulation was only significantly reduced in diluted samples in CO2atmosphere at T0 (P < 0.05). In diluted samples the incubation time significantly affected distribution of fast, slow, and medium subpopulations in CO2and CO2free atmosphere (P < 0.05), respectively. Viability, acrosome and mitochondrial integrity were not affected by CO2atmosphere (P > 0.05), however acrosome (at T0) and mitochondrial integrity (at T30) were significantly higher in CO2atmosphere in non-diluted and diluted samples (P < 0.05), respectively. The results of thein vitroanalysis of stallion semen were rather similar regardless of the atmosphere or dilution time.

En el presente artículo se analizan las relaciones entre las normas concebidas desde la burocracia de los partidos tradicionales, que amarran el futuro de las universidades a sus intereses particulares representados en los Consejos Superiores, a través de por lo menos dos figuras: la discrecionalidad y la delegabilidad, frente a los retos de la sociedad del conocimiento que invita a construir por consenso los escenarios de los proyectos de universidades del futuro donde las normas son soportes que garantizan la transformación colectiva. El argumento central de esta tesis considera que, primero, se concibe el nuevo proyecto de universidad del futuro y sus escenarios; segundo, se concertan los escenarios futuribles (1) de la universidad en una Asamblea general Universitaria, (2) (como el organismo de mayor poder democrático (3) universitario); tercero, se convierte en normas las decisiones asumidas por la Asamblea General Universitaria; cuarto se establecen los requisitos y compromisos económicos, científicos, tecnológicos y académico administrativos para la transformación y quinto se inicia el proceso de transformación universitaria con el concurso de los distintos actores políticos, académicos, culturales, sociales y productivos. Como estudio de caso se abordará la Universidad Surcolombiana.

CLÁUDIO PERANI E O PAPEL DA EDUCAÇÃO POPULAR NOS PARADIGMAS DE LIBERTAÇÃO E TRANSFORMAÇÃO SOCIAL NA AMAZÔNIA
Authors: Oliveira Márcia Maria de 
Published: September 2018

<div><p>A educação popular tem sido amplamente acionada para a formação de lideranças dos grupos de base e dos movimentos sociais. Representa um grande desafio para as instituições que contribuem nesses processos formativos, de maneira especial por causa da metodologia que requer técnicas que promovem maior participação e envolvimento das lideranças na formação. Este texto representa um breve recorte dos últimos quatro anos de Cláudio Perani (1932 – 2008) vividos à serviço da educação popular na Amazônia. Recolhe memórias de sua breve e intensa trajetória junto à equipe pedagógica do Curso de Formação para Ação Social, uma experiência de educação popular realizada no Serviço de Ação, Reflexão e Educação Social, que contribuiu para importantes mudanças nos paradigmas de libertação e transformação social na Amazônia. Retoma as etapas de elaboração de um “guia metodológico da educação popular” proposto por Cláudio Perani e desenvolvido de forma interativa com as lideranças populares no decorrer de sua formação. Os resultados dessa experiência comprovam a capacidade transformadora das lideranças em processos simultâneos de formação e intervenção social e celebram o legado de Cláudio Perani ainda muito presente nas trajetórias dos movimentos sociais na Amazônia.</p></div>
Proyecto Politico-Academico de la PatryTer - Revista Latinoamericana y Caribeña de Geografía y Humanidades
Authors: Costa Everaldo Batista da 
Published: September 2018

La grafía PatryTer trae el sentido bolivariano de la Patria Grande como unidad continental y de integración territorial, las cuales se singularizan por la forma y el contenido de las ciudades, el campo y la dominación hegemónica de la “naturaleza”, en América Latina y el Caribe. Ciudades, campo y “naturaleza” (como referentes geográficos) que tienen resignificado un sinnúmero de patrimonios populares y mundiales [lo urbano y lo rural - específicos de la región - son nuestro mayor patrimonio, cuando la masa de la población habita y reproduce sus vidas en las periferias de las ciudades y del campo]. En resumen, la idea representada en la grafía PatryTer no se restringe al debate relativo a los patrimonios continentales que el nombre de la revista induce de inmediato. Más que eso, desea fomentar la discusión regional-continental-internacional sobre los referentes geográficos: ciudad, campo y naturaleza socializada, en totalización, pues se encuentran en procesos permanentes de intervención espacial.
Paisaje industrial y sus representaciones
Authors: Cabrales Luis Felipe 
Published: September 2018

Se presenta un estudio histórico consistente en la deconstrucción de imágenes fotográficas y pictóricas de un paisaje industrial inserto en Guadalajara, la fábrica de jabones y perfumes La Parisiense, fundada en 1892. Tales representaciones, al igual que muchas otras, se utilizaron como vehículo de socialización y legitimación del régimen de Porfirio Díaz Mori, quien gobernó México durante el período 1877-1911. El tendido de una amplia red ferroviaria configuró nuevas articulaciones territoriales e impulsó el desarrollo industrial. Las lecturas reales y simbólicas del pasado se enlazan con una mirada actual del vestigio industrial de La Parisiense el cual afronta un doble embate, la degradación física y el olvido social, de ahí que la valorización del patrimonio cultural encuentre un aliado en el poder de las imágenes.
