In vitro propagation of Rosa ‘Konstancin’ (R. rugosa × R. beggeriana), a plant with high nutritional and pro-health value
Authors: Wojtania Agnieszka , Matysiak Bożena
Published: September 2018

The aim of the study was to develop an efficient micropropagation system for Rosa ‘Konstancin’, an interspecific hybrid between R. rugosa and R. beggeriana, whose fruits have high pro-health value. Shoot cultures were initiated from shoot buds collected in May and August from 15-year-old field-grown Rosa ‘Konstancin’ shrubs. The effect and interaction of different concentrations of phytohormones, sucrose and iron sources on in vitro initiation, multiplication and rooting of shoots were studied.

The time of collecting explants from donor plants significantly affected the initiation of shoot culture of Rosa ‘Konstancin’. Considerably higher frequency of bud break (100%) was obtained in explants isolated in August as compared to those collected at the end of May (30%). All buds developed into single shoots after 2-4 weeks of growing on the basal Murashige and Skoog medium containing 2.2 µM BAP, 0.3 µM GA3 and 88 mM of sucrose. The highest multiplication rate (4.8 shoots/explant) in a 5-week period was obtained on MS medium containing 50% of nitrogen salts, 3.1 µM BAP, 0.9 µM GA3 and 58 mM sucrose. High rooting frequency (100%) and quality of rooted plantlets was obtained on a medium containing 0.5 µM IBA, 138 µM Fe-EDDHA and 88 mM sucrose. Fe-EDDHA had a beneficial effect on the growth and photosynthetic activity of Rosa ‘Konstancin’ plantlets, which were successfully acclimatized ex vitro, with a more than 90% survival rate.
Mitigation of replant disease by mycorrhization in horticultural plants: A review
Authors: Lü Li-Hui , Wu Qiang-Sheng
Published: September 2018

Replant disease refers to the result of monoculture-continuous repetitive planting of congeneric crops or coordinal crops in the same soil for many years. Such disease is recognized as one of the main limiting factors affecting plant growth and production of horticultural plants in many countries. As a result, replant disease in horticultural plants has become a world problem in agriculture and also a bottleneck restricting the sustainable development of agriculture. In general, replant disease results in unfavorable growth of horticultural plants, which is due to allelopathy, autotoxicity, and the imbalance of both soil physical-biochemical traits and soil microflora. An environmentally friendly contribution to this could be bio-controlled by beneficial microorganisms. Arbuscular mycorrhizal fungi, one of soil-inhabiting fungi, can form a symbiotic association in roots to mitigate the negative effects of replant disease in many horticultural plants. Moreover, arbuscular mycorrhizal fungi do not produce any environmental pollution in soils and are a potential biological control. The soil fungi could regulate better morphological, physiological and molecular levels in plants to respond to the disease. This review mainly outlined the current knowledge in mycorrhizal mitigation of replant disease in horticultural plants, which appears to be a promising strategy to improve growth of horticultural plants in replant soils.

Published: September 2018

The low availability of soils with an appropriate pH value (4.2-5.2) is a factor limiting an increase in highbush blueberry acreage. The experiments examined the influence of a physiologically acidic urea phosphate fertilizer on the pH change of the soil and the mineral content in the soil, leaves, and fruit as well as polyphenols in the fruit of two highbush blueberry cultivars – ‘Sunrise’ and ‘Brigitta Blue’. The fertilizer, at doses of 30 and 60 kg of nitrogen per hectare, was used in the experiments in each of the three years of the study.

After using 60 kg N ha−1, urea phosphate caused a reduction in soil pH. It also significantly influenced the total soil nitrogen content – the average for the cultivars was 7.40 mg in 2015, while in the control plots – 1.85 mg 100 g−1. These quantities are above the optimum recommended for highbush blueberry. At the same time, low amounts of this ingredient were found in the leaves (‘Sunrise’ – 1.83 mg; ‘Brigitta Blue’ – 1.77 mg 100 g−1).

Even after the application of 30 kg of fertilizer in the second year, the phosphorus content in the soil was at a high level (> 4 mg 100 g−1). The amount of phosphorus also increased in the leaves and fruit. Despite considerable quantities of available magnesium in the soil after urea phosphate application, a significant reduction of this component was observed in the leaves and fruit compared to the unfertilized control bushes. The applied fertilizer reduced the amount of polyphenols in the fruit of the tested cultivars.

Published: September 2018

Inspiratory muscle training (IMT) is a strategy that has been used to improve performance in different sports modalities. This study investigated the effects of an IMT program on respiratory muscle strength and resistance as well as aerobic physical performance (PP) of handball athletes. Nineteen 20 ± 3 year-old male athletes were allocated into an experimental (EG, n = 10) or a placebo group (PG, n = 9). Their respiratory muscle strength was evaluated by measuring the maximum inspiratory and expiratory pressures (MIP and MEP), muscular respiratory resistance by maximum voluntary ventilation (MVV) and aerobic PP by the cardiopulmonary exercise test. The study was designed to evaluate the effects of a 12-week IMT program with five sessions a week. A significant difference was observed in the pre and post IMT values of the MIP (170 ± 34 to 262 ± 33 cmH2O) and MEP (177 ± 36 to 218 ± 37 cmH2O) in the EG, and MIP (173 ± 45 to 213 ± 21 cmH2O) in the PG, with a large effect size for the MIP, when the groups were compared. MVV showed a significant increase (162 ± 24 to 173 ± 30 L) in the EG, with a small effect size. There was a significant difference in maximum oxygen uptake (54 ± 8 to 60 ± 7 ml/kg/min) in aerobic PP. Oxygen uptake at the respiratory compensation point (RCP) (46 ± 6 to 50 ± 5 ml/kg/min), with a moderate effect size for both variables, was observed in the EG after IMT. We concluded that IMT provided a significant increase in respiratory muscle strength and resistance, contributing to increased aerobic PP in the EG, which suggests that IMT could be incorporated in handball players’ training.

Published: September 2018

The aim of this study was to compare and examine differences in several neuromuscular assessments between female national Olympic team (Rio-2016) and national college team handball players (2015-Gwangju Summer Universiade). Twenty-eight elite female handball players of the national Brazilian Olympic (n = 12) and college (n = 16) teams participated in this study. The Olympic and college athletes performed the following speed-power tests assessing mean propulsive power (MPP) in loaded jump squat (JS) and bench press (BP) exercises, unloaded squat and countermovement jumps (SJ and CMJ), sprint performance over 5-, 10-, and 20-m, and change of direction ability in a standard Zig-zag test and a T-Test. The differences between Olympic and college team performances in all variables were analyzed using the magnitude-based inference. The Olympic group presented likely higher performances in the SJ, CMJ, and MPP JS and very likely higher performances in the MPP BP and T-Test than the college group. The differences in the linear sprint velocity in 5-, 10-, and 20-m tests as well as in the Zig-zag test were all rated as unclear. These findings may have substantial implications for the development of effective strength-power training and testing strategies in elite handball. In addition, coaches and researchers can use these data to create efficient talent identification programs for youth handball players.

Published: September 2018

The aim of this study was to compare the effects of plyometric and jump training on physical performance in young male handball players. Twenty-six young male handball players were divided into two sub-groups to perform a five-week pre-season training programme supplemented with two ground-reactive protocols with an equal number of jumping exercises referred as to ground contacts: plyometric training (PLY; n = 14) and standard jump training (CON; n = 12). Before and after training, repeated sprint ability (RSA), jumping ability (JA), maximal oxygen uptake (VO2max) and aerobic power at the anaerobic threshold (PAT) were measured. A two-factor analysis revealed significant time effects with improvements in fat mass (p = 0.012), maximal power during the incremental cycling test (p = 0.001) and PAT (p < 0.001), power decline (PDEC) and maximal power (Pmax) in the 5th repetition (p < 0.05 and p < 0.01, respectively). The training-induced changes in absolute and relative peak power in the RSA test and absolute VO2max approached significance (p = 0.06, p = 0.053 and p = 0.06). No intervention time × exercise protocol effects were observed for any indices of JA, RSA and aerobic capacity. A five-week pre-season conditioning programme supplemented with only 15 sessions of plyometric exercise did not induce any additional benefits, compared to a matched format of standard jump training, in terms of improving jumping performance and maximal power in the RSA test. Aerobic capacity and the fatigue index in RSA were maintained under these two training conditions.
Temporal adaptation control for local tone mapping operator
Authors: El Mezeni Dragomir , Saranovac Lazar
Published: September 2018

High dynamic range (HDR) imaging has gained great popularity over the past twenty years. Tone mapping operator (TMO) is the key component that enables reproduction of HDR images on the standard low dynamic range (LDR) display devices. When it comes to the HDR video, design of the TMO becomes especially challenging since temporal control of TMO parameters is needed in order to avoid possible artifacts. Since temporal and spatial contrast cannot be met simultaneously, existing solutions are usually designed to optimize one of these two requirements. We present novel local tone mapping operator that preserves details and simultaneously provides good local and global contrast of processed images. Tunable temporal control enables trade-off between spatial and temporal contrast of a tone mapped video. Flexible control presented in this paper ensures that both requirements can be met with a single operator just by using different tuning of the control block.When compared to the state-of-the-art TMOs, proposed solution exhibits better results regarding overall image quality.
Architectural approach to cope with network-induced problems in network control systems design
Authors: Popović Ivan , Rakić Aleksandar
Published: September 2018

In the field of process control engineering, network-based systems enable extensive, flexible and scalable applications in industrial automation and control. However, network-induced problems are influencing the stability and performance and they are introducing constraints in the system design and operation. While most of the existing design methodologies are searching for the specific solution within the domain of the control theory, we propose the comprehensive architectural approach that addresses wide range of the network-related issues and copes with them in the effective way. Presented solution combines several architectural styles encapsulating the actuating, sensing and control functionality into the unified service-oriented components, while the data transport is supported through event-triggered distributed middleware components. Given architectural approach decouples the design of process control functionality from the properties of the control network infrastructure. The effectiveness of the proposed solution is verified through the analysis of the system operation in the given case-study.
A scheme for comprehensive computational cost reduction in proper orthogonal decomposition
Authors: Singh Satyavir , Bazaz M Abid , Nahvi Shahkar Ahmad
Published: September 2018

This paper addresses the issue of offline and online computational cost reduction of the proper orthogonal decomposition (POD) which is a popular nonlinear model order reduction (MOR) technique. Online computational cost is reduced by using the discrete empirical interpolation method (DEIM), which reduces the complexity of evaluating the nonlinear term of the reduced model to a cost proportional to the number of reduced variables obtained by POD: this is the POD-DEIM approach. Offline computational cost is reduced by generating an approximate snapshot-ensemble of the nonlinear dynamical system, consequently, completely avoiding the need to simulate the full-order system. Two snapshot ensembles: one of the states and the other of the nonlinear function are obtained by simulating the successive linearization of the original nonlinear system. The proposed technique is applied to two benchmark large-scale nonlinear dynamical systems and clearly demonstrates comprehensive savings in computational cost and time with insignificant or no deterioration in performance.
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

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

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

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.

Authors: Prishtina Shkumbin Munishi
Published: September 2018

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.

The 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.

Published: September 2018

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

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.

Published: September 2018

Dicoumarol 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).

Published: September 2018

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

The 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.

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

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.
Flow Battery Electroanalysis 2: Influence of Surface Pretreatment on Fe(III/II) Redox Chemistry at Carbon Electrodes
Authors: Sawant Tejal , McKone James
Published: September 2018

Redox flow batteries are attractive for large-scale electrochemical energy storage, but sluggish electron transfer kinetics often limit their overall energy conversion efficiencies. In an effort to improve our understanding of these kinetic limitations in transition metal based flow batteries, we used rotating-disk electrode voltammetry to characterize the electron-transfer rates of the Fe3+/2+ redox couple at glassy carbon electrodes whose surfaces were modified using several pre-treatment protocols. We found that surface activation by electrochemical cycling in H2SO4(aq) electrolyte resulted in the fastest electron-transfer kinetics: j0 = 0:90 mA/cm2 in an electrolyte containing 10 mM total Fe. By contrast, electrodes that were chemically treated to either remove or promote surface oxidation yielded rates that were at least an order of magnitude slower: j0 = 0:07 and 0:08 mA/cm2, respectively. By correlating these findings with X-ray photoelectron spectroscopy data, we conclude that Fe3+/2+ redox chemistry is catalyzed by carbonyl groups whose surface concentrations are increased by electrochemical activation.

Inks for the inkjet-deposition of Titanium dioxide and hybrid organic inorganic perovskites were synthesized and then used to deposit films for high efficiency perovskite solar cell devices. The inkjet-printed titanium dioxide electron transport layer was optimized in reference to state-of-the-art spin-coated tio2 films. After observing that the printed TiO2 films perform at least as well as the spin-coated version, this charge transport layer was used as the anode for inkjet-printed perovskite absorber layers. Using printed TiO2 and perovskite, 14.1% power conversion efficiency was achieved.

O debate assumido pela PatryTer diz respeito às dinâmicas territoriais urbanas, rurais e meio-ambientais na América Latina e Caribe. Neste editorial, queremos lembrar a ideia contida no Projeto Político-Acadêmico da revista [também publicado neste número], referente ao nosso objetivo que é fomentar a discussão regional-continental-internacional sobre os referentes geográficos: cidade, campo e natureza socializada, em totalização, pois em processos permanentes de intervenção espacial e ressignificação.
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.
Patrimonio y paisaje urbanos en Argentina
Authors: Martínez Irene , Percara Melisa Luciana
Published: September 2018

El impulso de la actividad constructiva, a partir de la recuperación económica luego de la crisis del 2001 en la Argentina, modificó valores en el patrimonio y paisaje de determinados entornos urbanos. El presente artículo aborda el caso del barrio Candioti Sur de la ciudad de Santa Fe - Argentina en un periodo de 2001 a 2013, donde un acelerado proceso de transformación urbana pone en riesgo los valores ambientales (patrimoniales y paisajísticos) del lugar. Reflejándose en un conflicto en la coexistencia de dos procesos urbanos: proceso de consolidación y proceso de transformación. Se estudia la problemática a partir de un análisis urbanístico del barrio que implica el estudio particularizado del tejido urbano, el paisaje urbano y los instrumentos normativos implicados.
Cidades, território e memória na América Latina
Authors: Lemos Amália Ines Geraiges
Published: September 2018

Procuramos analisar os territórios das nossas metrópoles a partir dos conceitos do processo civilizatório de Norbert Elias, que destaca a diferença entre civilização e cultura. Ressaltamos que a chegada e ocupação dos espanhóis, portugueses, franceses, holandeses, irlandeses e outros para a América, especialmente para a América Latina, semeou novas formas de ocupação e de colonização que é o resultado de um processo civilizatório. Para a sociedade ocidental, o que não correspondia às suas vivências e suas experiências, eram rotuladas como não civilizadas ou "mais primitivas". Também tomamos os conceitos de território de Milton Santos como um paradigma para o qual com ambos os conceitos formulamos a análise de diferentes processos históricos dos territórios que se produziram nas metrópoles latino-americanas, demonstrando que não existe o rótulo ideológico denominado "fim dos territórios".
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.
Digital Means for Reducing Digital Inequality: Literature Review
Authors: Maceviciute Elena , D. Wilson Thomas
Published: September 2018

Aim/Purpose: The aim of this paper is to identify the possibilities for reducing the second and third levels of the digital divide (or inequality) through conscious application of digital technologies, especially through the promotion of digital means for information, enlightenment, and entertainment.

Background: This article reviews studies carried out between 2000 and 2017, which investigate the social benefits of digital technology use for disadvantaged user groups and, especially, of their outcomes in terms of increasing digital skills and motivation to use information and communication technologies.

Methodology: The literature review of the selected texts was carried out using thematic content analysis. The coding scheme was open but based on the theory of three levels of digital divide by van Dijk.

Contribution: The results of the analysis show the difficulties related to the attempts of reducing the digital divide on the second and third level using only digital interventions, but also reveal the potential of these interventions.

Findings: The literature review confirms the connection of different levels of digital divide with other relational and structural inequalities. It provides insights into the strengths and weaknesses of digital interventions aimed at the reduction of digital inequalities. Their success depends on the consideration of the context and participants needs as well as on carefully planned strategies.

The paper summarizes and demonstrates the shortcomings and limitations of poorly designed interventions in reducing the digital divide but emphasizes the possibilities of raising the motivation and benefits for the participants of strategically planned and implemented projects.

Recommendations for Practitioners: While planning a digital intervention with the aim of reducing digital inequalities, it is necessary to assess carefully the context and the needs of participants. Educational interventions should be based on suitable didactic and learning strategies.

Recommendation for Researchers: More research is needed into the factors that increase the effectiveness of digital interventions aimed at reducing the digital divide.

Future Research: We will apply the findings of this literature review in an intervention in the context of Lithuanian towns of different sizes.
