BIM PROCESS, ONTOLOGIES AND INTERCHANGE PLATFORM FOR CULTURAL ARCHITECTURAL HERITAGE MANAGEMENT: STATE OF ART AND DEVELOPMENT PERSPECTIVES
Authors: Pili A.
Published: May 2019

Abstract. Ontology meaning and its declination in computer science are defined in the contribution. Some experiences of using ontologies for Cultural Heritage frame the state of the art. Specific ontologies for the conservation process allows the definition of classes and their description through attributes. Subjects, means, tools, relationships, and planning of activities, times and costs are included in the process. Ontologies so defined are also the basis for the definition of an interoperability protocol for Cultural Heritage. Interoperability means exchange among the tools, with the guarantee that data and meanings transmitted are correctly interpreted by the receiving system. The paper proposes the kind of informative model for built heritage. Defining the basis for ontologies is the goal. The flow of information in a Common Data Environment, a data exchange platform, is necessary to ensure proper data and process management.

Abstract. Subglacial discharge has significant impacts on water circulation, material transport, and biological productivity in proglacial fjords of Greenland. To help clarify the fjord water properties and the effect of subglacial discharge, we investigated the water mass structures of Bowdoin Fjord in northwestern Greenland based on summer hydrographic observations, including turbidity, in 2014 and 2016. We estimated the fraction of subglacial discharge from the observational data and interpreted the observed differences in subglacial discharge behavior between two summer seasons with the numerical model results. At a depth of 60–80 m, temperature profiles were distinctively different in 2014 and 2016, and a larger fraction of submarine meltwater was detected in 2014. At a depth of 15–40 m, where the most turbid water was observed, the maximum subglacial discharge fractions near the ice front were estimated to be ~ 6 % in 2014 and ~ 4 % in 2016. The higher discharge fraction in 2014 was due to the stronger stratification, as suggested by numerical experiments performed with different initial stratifications. Turbidity near the surface was higher in 2016 than in 2014, suggesting a stronger influence of turbid subglacial discharge. The higher turbidity in 2016 could primarily be attributed to a greater amount of subglacial discharge, as inferred from the numerical experiments forced by different amounts of discharge. This study indicates that ambient fjord stratification difference is an important factor controlling the vertical distribution of subglacial discharge, together with its amount.

Published: May 2019

Edible by-products are a good source of nutrients and bioactive substances and could be used as functional ingredients or for biopeptides production natively contained in raw materials. A wide range of peptides are also formed during the enzymatic hydrolysis or food processing. The comparative results of the effectiveness of isolated certain protein and peptide fractions by ultrafiltration with the same natively presented in raw tissues, as well as the influence of heat treatment on biological activity of origin active substances are presented. The model of rat alimentary hyperlipidemia was developed by adding cholesterol and fat to the standard diet and vitamin D2 injection per os. Serum lipid profile was determined on automatic analyzer BioChem FC-360. Dynamic of changes in serum lipid profile was assessed as corresponding control group medium results in ratio to certain rat data. Two-dimensional electrophoresis (2DE) was performed according to the method of O’Farrell with isoelectric focusing in ampholine pH gradient (IEF-PAGE) with following identification by MALDI-TOF MS and MS/MS mass spectrometry. Consumption of native pig aorta and pig heart during 14th days led to normalization of lipid profile in serum of hyperlipidemic rats, while low molecular weight (LMUF, MW <5 kDa) and medium molecular weight (MMUF, MW = 5 – 30 kDa) ultrafiltrates of pig aorta extract did not strongly influenced on level of triglicerides and, on contrary, elevated high density cholesterol. Consumption of developed product by hyperlipidemic rats during 28th days did not lead to significant changes in serum lipid profile, while on 42nd day all ratios reached ones in group, which were treated with native raw material or isolated active fractions. The stability of developed product was confirmed by proteomic studies. Obtained results open prospects to modernization the technology, presumably use as a matrix dietary meat (e.g. poultry) with incorporated active identified components.

Published: May 2019

Aiming to verify the insecticidal potential of 16 native plants from the Araripe National Forest (ANFO) on L3 Aedes aegypti larvae in laboratory conditions, were researches performed in controlled conditions of temperature, air relative humidity and photophase, in a type B.O.D. climatized chamber, executed in period from August/2016 to May/2017. The adopted experimental design was completely randomized, represented by ethanolic extracts obtained from 16 native plants, besides the witness without application and with pyriproxyfen as chemical insecticide, conducted with four replicates in each plant extract. The application of the extracts was performed only once, and at 24, 48 and 72 hours, after the infestation, was determined the effects of the extracts on larval mortality. The extracts of Amargoso, oil’tree, Lacre, Cajui, Louro smelling, Field Rosemary, Murici truthful, Janaguba and laranjinha provoke mortality above of 90% to the larvae of Aedes aegypti after three days of exposure, in the dose of 50 mL of the extracts. After 24 hours of exposure, the ethanolic extracts from barks and leaves of Field Rosemary and of laranjinha killed all the larvae. On the other hand, the extracts with higher larvicide potential were evaluated at different doses (i.e., 12.5, 25, and 50 mL/L) in a 9 × 3 factorial scheme, with four replicates. The ethanolic extract of the leaves of Louro smelling is the most efficient, because in any dosage it eliminates all the larvae of Aedes aegypti, thus demonstrating to be an excellent vegetable larvicide in the control of this vector after three days of exposure, whereas the bark extract of the oil’tree is the least effective. The alkaloids and flavonoids are present in the leaves of the Louro smelling.

The productivity of citrus plants has not reached its maximum potential due to the action of several factors that directly affect agricultural profitability. Among these factors, weed interference has a great importance since it causes a reduction in crop productivity. The aim of this study was to assess the effect of different cover crops on suppression of weeds in an orange orchard. The research was conducted in a commercial orange production area located in Rio Preto da Eva, AM, Brazil. The experimental design was a randomized block design with six treatments and four replications. Treatments were control, millet, jack bean, forage turnip, brachiaria, millet + jack bean. The evaluated characteristics were weed density, soil cover percentage, total weed dry matter, total cover plant dry matter and growth indices (leaf area index, leaf area ratio, and specific leaf area). Cover plants provided a good dry matter production and had a suppressive effect on weed growth, except for forage turnip. Brachiaria and jack bean presented the highest values of leaf area index and leaf area ratio.

The propagation of gabirobeira is carried out by seeds. However, the recalcitrance and not tolerance of the seeds to the storage compromise the formation of seedlings. Thus, the propagation by cuttings can be an option, being able to provide significant results in different seasons. The objective of this work was to evaluate the vegetative propagation by stem cuttings of two species of gabirobeira (Campomanesia adamantium and Campomanesia pubescens) associate to indolbutyric acid (IBA) at differents seasons of the year. Cuttings of the two species were obtained in the 4 seasons and concentrations of 0, 2000, 4000, 6000 and 8000 mg L-1 of IBA were used, by immersion in the solution for 15 seconds and sequentially staked on trays containing a sand substrate. Sixty days after experiments were set it was evaluated the percentage of cuttings with shoots, live cuttings, dead cuttings, cuttings with calluses and rooted cuttings. A completely randomized design with 5 treatments, 4 replicates and 8 cuttings per plot was adopted. During the whole experiment, the greenhouse, substrate and cutting leaves temperature was monitored. The use of IBA did not promote adventitious rhizogenesis, but provided a high percentage of survival for the species Campomanesia adamantium and Campomanesia pubescens by stem cuttings during the spring season.

Published: May 2019

Soybean charcoal rot is a widespread root disease caused by the fungus Macrophomina phaseolina, a natural soil inhabitant that has great pathogenic variability and high survival capacity under adverse conditions. There are no registered fungicides or genotypes genetically resistant to this disease, although differences in susceptibility have been observed. As the fungus is a seed-borne pathogen, screening methods based on seed inoculation are quick and efficient. The objective of this work was to assess the efficiency of soybean seed infestation by incubation for 48 h with colonies of M. phaseolina, comparing two germination environment methods (germination paper or in pots with substrate), and to correlate the relative germination of genotypes of both methods with the severity of charcoal rot observed in a field test. The results showed that 48 h were sufficient to infest seeds and reduce the germination. The germination in paper was higher at 5 days after sowing (DAS) than that in pots at 8 DAS in a greenhouse. Both environments exhibited a highly negative correlation between seed germination and field disease severity (r = -0.775 in germination paper and r = -0.779 in pots with substrate). It is recommended that the germination test be performed in germination paper due to practicality and economy of space, material, and labor besides the better control of the environment.

Atemoya currently has its seeds studied in several aspects, from the technological and physiological point of view. However, for the performance of the germination test, there is no standardization in relation to the number of seeds and replicates. Thus, this work aims to determine the optimal sample size for germination tests with atemoya seeds. A germination test was carried out with 5 treatments, considering 10, 20, 30 40 and 50 seeds per sampling unit with 50 replicates of each. Data were analyzed using logistic regression, non-linear Gompertz regression models, bootstrap simulation and graphs in the form of contour lines in order to be able to infer the best binomial of the number of seeds per sampling unit and the number of replicates. The expected germination percentage, maximum germination speed and times for the beginning of the germination process, maximum germination speed and interruption of the germination process were determined. The treatment of 20 seeds per sampling unit statistically differs from that of 40 seeds by the Tukey-Kramer test with 5% significance. It could be concluded that for germination tests with atemoya seeds to have statistical validity, the smallest sample size is 10 seeds per unit, regardless of number of replicates.

In function of the green revolution the indiscriminate use of agrochemicals and pesticides in agriculture has been also shown in the production of medicinal plants, resulting in the increase of productivity but with high residual contamination and low rates in the production of secondary metabolites responsible for the biological and pharmacological activity in vegetable drugs. In another hand, new techniques of elicitation has been applied to stimulate the medicinal plants production through the organic and agroecological management, contributing for the increase of performance, quality and production. In this context, it is aimed with this review to present such as the humic substances: fulvic acid, humic acid and efficient microorganisms which influence and help the ontogeny and the secondary metabolites production of medicinal plants. The reviewed articles show that the use of fulvic acid, humic acid and efficient microorganisms in the production of medicinal plants contributes on the increase of biosynthesis, secondary metabolites production such as coumarins, alkaloids, phenylpropanoids and essential oils, as well as the increase of nutrients absorption, growth and development of species.

Published: May 2019

The use of good quality seeds is fundamental for proper establishment of a crop. In this way, for more precise determination of seed quality, vigor tests are performed in addition to the germination test. These tests enable the selection of the best lots for commercialization and planting. This study evaluates the effects of temperature and exposure times of the accelerated aging test for vigor classification of mungbean seed lots. Seeds of the mungbean cultivar Esmeralda were used, being obtained from four cultivated plots at the State University of Goiás (UEG), Ipameri Câmpus, in the 2013, 2015, 2016, and 2017 harvests. The lots were initially characterized using germination and vigor tests (first germination count, germination rate index, seedling length, and seedling fresh and dry weight). The accelerated aging test was conducted with a completely randomized experimental design, in a 2 × 4 factorial arrangement consisting of two temperatures (40 and 42 °C) and four times (24, 48, 72, and 96 hours), with four replicates of 50 seeds per lot. The lots showed significant differences in the germination test, first germination count, germination rate index, and seedling length. The accelerated aging test was efficient in classifying lots. Lot 3 obtained the best results, while lot 1 obtained the lowest ones. The combination of 42 °C temperature and 72 h of seed exposure to the accelerated aging test is the best to classify mungbean seed lots.

Published: May 2019

The tomato crop is almost totally irrigated. Among the irrigation methods utilized, mechanized sprinkling by center pivot stands out in tomato cultivation. A cultural treatment used in the tomato is the synchronization of the irrigations with the applications of the pesticides since with the leaf wetting the plants become unprotected and susceptible to diseases. In an attempt to reduce pesticide applications, growers seek to increase the time between irrigations, however, there are limitations, inherent to the soil and the irrigation system itself. The objective of this work was to simulate the soil water runoff tendency for irrigation management in the tomato crop, simulating three different types of soils (sandy, medium and clayey), three declines (0, 5 and 10%), and two types of deflectors (I-Wob and Spray). For this, four pivot sizes (25, 50, 75 and 100 ha) were defined and the methodology of maximum allowable precipitation estimated by the Newton-Raphson numerical technique was used to verify the different runoff conditions. The results showed that clayey soils are more susceptible when compared to medium and sandy soils, to surface runoff. Pivots of 100, 75 and 50 ha present greater susceptibility to runoff, with 25 ha being the best suitability for infiltration capacity in both soils. There is a percentage reduction of the maximum allowable rainfall of 40.74 % (±1.54) when the terrain is plan and pass to have 5% inclination and 22.99% (±1.47) between 5 and 10 %. I-Wob type deflectors have a better distribution of application, a consequently better relation with the maximum allowable precipitation intensity and less possibility of the surface runoff.

Caesalpinia pulcherrima is an exotic shrub species, belonging to the Fabaceae family, that has medicinal properties, and is widely used for urban afforestation. The objective of this research was to evaluate the overcoming of the C. pulcherrima seed dormancy, the influence of temperature, storage, and water quantity on the substrate in the germination of the species, as well as the use of the tetrazolium test for viability analysis. The analyzes were carried out at the Plant Propagation Laboratory at the Agricultural Sciences Center of the Federal University of Alagoas, in the municipality of Rio Largo, Brazil, and at the Laboratory of Plant Physiology, Arapiraca Campus, at the same University. The experiments were performed under a completely randomized design, with four replicates of 25 seeds. The results demonstrated that during storage the seeds developed a possible secondary dormancy, which was overcome with a time of twelve months of storage. The C. pulcherrima seeds subjected to the test of light qualities presented a significant difference in their germination percentage when verified with the time of storage. In the far-red quality, the newly harvested seeds had a germination percentage of (98%), higher than seeds with 12 months of storage (80.5%). The water volume 3.5-fold the weight of the dry paper provides (90%) germination when compared to other volumes. The tetrazolium salt concentrations of 0.075% and 0.1%, under the temperature of 30°C within 2 hours, are indicated for the viability analysis of Caesalpinia pulcherrima seeds.

Zea mays L. presents socioeconomic and cultural importance for the Northeast region of Brazil, its yield is directly related to the productive system, to the edaphoclimatic conditions and to the soil management. The aim of this work was to evaluate the development and the yield of maize under different nitrogen doses in rainfed conditions in the Brazilian semiarid. The experimental design was in randomized blocks, with four treatments and five replications, totalizing 20 experimental plots, with 24 plants each. The treatments were: T1 (0 kg ha-1 of N); T2 (40 kg ha-1 of N); T3 (60 kg ha-1 of N) and T4 (80 kg ha-1 of N). Were evaluated: plant height, culm diameter and number of leaves at 30, 45, 60, 75 and 90 days after emergence; leaf temperature, stomatal conductance, transpiration, liquid photosynthesis and intercellular carbon concentration at 65 days after emergence; yield, shoot dry mass and nitrogen content in the soil after harvest. The different nitrogen doses significantly influenced the plant height, culm diameter and the number of leaves in the different evaluation periods, also influencing the nitrogen levels in the soil after the harvest. There was no difference among treatments for the yield, the registered average was 5,205 kg ha-1. The development of the crop and the nitrogen absorption may have been influenced by the water deficit during the crop cycle. The maize presented better agronomic performance with the dose of 60 kg ha-1 of nitrogen.

Published: May 2019

Aim was to evaluate the usability of mini-screw (Temporary Anchorage Devices TADs), as an anchor unit (units), in the treatment of gummy smile associated with deep over-bite. The sample was made up of 15 adult gummy smile patients (2males and 13 females).Materials and Methods All patients suffered from increased anterior facial height. Pre-treatment and post-intrusion gingival smile line (GSL), which is the distance between cervical gingival margins of maxillary central incisors and the lower border of the upper lip during smiling, was measured in millimetres using a digital calliper. Four TADs were used for each patient: two anterior TADs that were inserted between the roots of lateral incisors and canines; and the other two TADs were inserted posteriorly, between the roots of 2nd premolars and 1st molars. The anterior TADs were used as anchor units for the intrusion of upper anterior teeth, while posterior TADs were used for en-mass retraction. Pre-treatment and post intrusion lateral cephalometric radiographic measurements were taken for statistical inferences. Statistical analyses were carried out using Wilcoxon signed rank test. Statistical analyses revealed significant reduction in GSL and overbite.Results Radiographically, there were significant changes in the vertical and antro-posterior positions of upper anterior teeth, but no significant changes have been noticed in the vertical position of upper or lower posterior teeth.Conclusions The findings of the present study indicate that gummy smile which is mainly due to maxillary dentoalveolar overgrowth can be treated effectively with intrusion using anterior TADs, particularly in case of divergent face. The findings also indicate that anterior and posterior TAD scan provide absolute anchorage for treatment of deep overbite, and increased overjet.

Cooperation in the humanitarian sphere is one of the priorities in the activities of the Shanghai Cooperation Organization (SCO). Over the years of the existence of the SCO, the countries that belong to it, have established practical and effective cooperation in the fields of culture, education, environmental protection, youth policy, sports, tourism and media. As the SCO is adding its members, this form of interaction starts playing an increasingly important role. The SCO countries have certain achievements in developing various aspects of humanitarian cooperation. Student, teacher and academic staff exchange projects are being realized, direct contacts between educational institutes have been established; languages, history, culture, and literature of the SCO member states are being studied. Multilateral mechanism of interaction has been formed — meetings of the ministers of education of the SCO member states; a permanent expert group, which coordinates joint efforts in this area, has been created.

Published: May 2019

Electrochemical characterization of ascorbic acid oxidation on a graphite screen printed electrode (SPE) modified with La3+/Co3O4nanocubes is performed by applying cyclic voltammetry (CV), chronoamperometry (CHA), and differential pulse voltammetry (DPV) techniques. Synthesized La3+/Co3O4nanocubes for SPE modification, La3+/Co3O4/SPE, enhance the ascorbic acid electrooxidation kinetics by reducing the anodic overpotential. Excellent La3+/Co3O4/SPE electrochemical properties provide sensitive ascorbic acid voltammetric determination with low detection limit, good stability and quick response towards electrooxidation of ascorbic acid as compared to bare SPE. Under optimized conditions, DPV current demonstrates a linear response for ascorbic acid over a concentration range of 1.0 to 900.0 mM with a correlation coefficient of 0.9997, and detection limit (LOD) (S/N = 3) = 0.3 mM. The proposed procedure offers a potential application for producing the sensor with good repeatability. Also, fast response of fabricated sensor can allow a real-time analysis of real samples.

Introduction: Observations indicate that struggling with a burden of an incurable disease such as advanced chronic obstructive pulmonary disease (COPD) may result in the weakening of an individual sense of dignity, and be a source of spiritual suffering. Clinicians providing respiratory care to patients should be open to their spiritual needs, in the belief it may improve coping with the end-of-life COPD. The study aimed to assess overall feasibility and potential benefits of Dignity Therapy (DT) in patients with advanced COPD. Material and methods: Patients with severe COPD, in whom a DT intervention was implemented according to the protocol established by Chochinov et al. were included into the study. An self-designed questionnaire was applied to assess the patients’ satisfaction after intervention. Subsequently, the patients’ statements were allocated to specific problem categories, corresponding to the spiritual suffering concerns, as structured by Groves and Klauser. Results: DT was completed in 10 patients, with no unexpected side effects. Satisfaction Questionnaire showed a positive effect of DT on the patient’ well-being (3.9 on a 5-point Likert scale). The analyses of the patients’ original statements enabled an effective identification of the spiritual suffering and spiritual resources and faced by COPD patients. Conclusions: DT is an intervention well received by COPD patients, which may help them in recognising and fulfilling their spiritual needs in the last phase of their life. Information acquired on the patients’ resources and spiritual challenges may help clinicians improve their care, especially with regard to supporting their patients at the end-of-life stage.

Published: May 2019

Discute a importância da gestão profissional de crises com repercussão comunicacional, na medida em que essas crises fazem parte do cotidiano das organizações de um modo geral, inclusive estão presentes na realidade da Igreja Adventista do Sétimo Dia no Brasil. Essas crises interferem na forma como os públicos enxergam e formam sua percepção de uma determinada organização e podem se constituir em elementos capazes de afetar a imagem corporativa. A proposta é estabelecer, por isso, uma relação entre o que essas crises representam para a própria imagem da organização em termos de impacto e influência, avaliando qual seria a relevância de se geri-las adequadamente sob o ponto de vista comunicacional. Por meio de pesquisa exploratória e qualitativa, além de conceituar as crises de imagem na organização, inclusive como algo inerente a qualquer tipo de organização, vamos discutir o conceito de imagem corporativa da organização a partir de um olhar sobre os estudos teóricos voltados à reflexão de imagem no contexto da semiótica da cultura e suas diferentes implicações, especialmente estratégicas para uma organização.
Colonialidade da memória: apagamentos da luta pela terra Guarani e Kaiowá na constituição do moderno agronegócio brasileiro
Authors: De Oliveira Luciana , Bomba Pedro
Published: May 2019

No artigo buscamos delinear o dispositivo de colonialidade da memória obviando a relação entre genocídio indígena e a campanha publicitária "Agro: indústria-riqueza do Brasil", a partir do caso do povo Kaiowá (MS/Brasil). Buscamos caracterizar tal arranjo discursivo a partir do gesto metodológico que soma análise de conteúdo e pesquisa etno-histórica a partir de: 1) dados históricos de violação de direitos dos Guarani e Kaiowá no Relatório Figueiredo e dados atuais produzidos acerca de mortes violentas bem como seus enquadramentos e reverberações midiáticas; 2) a propaganda do chamado "novo rural brasileiro" e recordes produtivos do agronegócio. O objetivo é mostrar que tal dispositivo não é parte de um passado distante mas que reatualiza memórias nas mídias como forma contemporânea da colonialidade do poder.
Characterization of Buffalo Dairy Production Systems in Egypt Using Cluster Analysis Procedure
Authors: Abdel-Salam S.A.M.
Published: May 2019

The study objective was to characterize and classify buffalo dairy production systems in Egypt. Ten governorates having high buffalo population density were selected as the study area. The data were collected from 1811 dairy buffalo farms using survey. Buffalo holders were face to face interviewed by constructed questionnaire. The survey was applied in two years (2010 and 2011). Two-Step Cluster procedure (CA) was used and analysis was repeated several times until the cluster quality came good (average silhouette ≥0.5). The algorithm selected the number of clusters, after calculating the Akaike’s information criterion (AIC). Statistics of CA showed that the numbers of farm in each cluster were 43 (2.4%) in cluster1 (CL1), 1364 (75.3%) in cluster2 (CL2) and 404 (22.3%) in cluster3 (CL3). CL1 farms had a good availability of facilities. The management practices were the higher in comparison with the farms in the other clusters. Management and feeding systems practices in CL1 ranged from medium to high. CL2 was the largest, with 1364 farms located in all the ten governorates. The availability of facilities and equipment were low or lacking. The management practices were the lowest in comparison with farms in other clusters. CL3 facilities availability were low to medium. The management practices were medium when compared with the farms in the other clusters. The results of the current study demonstrate the existence of a large variability among buffalo dairy production systems in Egypt. These systems variability should be taken into consideration for sustainable system development.
Improving leg health in broiler chickens: a systematic review of the effect of environmental enrichment
Authors: Pedersen IJ , Forkman B
Published: May 2019

Leg problems are highly prevalent in modern broiler production and provision of environmental enrichment could be a strategy to improve leg health. Different types of environmental enrichment have undergone evaluation. Our objective was to conduct a systematic review of the effect of environmental enrichment on leg health in broiler chickens. The evaluation of leg health included measures of the entire leg and foot, and behavioural, pathological and physical measures. Six types of environmental enrichment were selected for inclusion: light programme, intensity of light, stocking density, perches, straw bales and separation of resources. For each type, a systematic literature search was performed. The review included 62 studies; 56 randomised trials and six cross-sectional studies. An assessment of the methodological quality of all 56 randomised trials was performed with some reporting deficits regarding occurrence of blinding, randomisation and reliability of measures. Provision of perches and increased intensity of light only displayed limited effectiveness in improving leg health and both mainly affected contact dermatitis. In contrast, there was evidence that a lowered stocking density and a dark/light schedule could improve leg health. Few studies have been carried out on the effect of straw bales and separation of resources. The few studies done have, however, shown that both types of enrichment can be effective in improving leg health. In conclusion, identifying and providing the optimal types of enrichment for broilers will reduce leg problems and increase mobility, thereby improving the welfare of the birds.
