title: Information retrieval in linked data: A model based on concept maps and complex networks analysis

description: Abstract This article presents a model for information retrieval in linked open data using methods and complex network operations for ranking and selecting information, and concept maps for presenting the retrieved information to the user. The model shows the relationships between query terms that represent an informational need and presents them as concept maps. The underlying hypothesis is that the user’s relationship to the retrieved information occurs in the light of Brookes’ fundamental equation of information science. The cognitive structure of the cognoscente is a complex network that is modulated by the retrieved information which, in turn, is derived from a complex network. The final complex network is mapped into a resulting concept map enhanced by heuristics, such as the application of controlled vocabulary. The first study conducted, with qualitative characteristics and using an exploratory approach, was an information retrieval pilot test. It allowed the assessment of the algorithms used in the ranking and selection of the intermediate information networks and provided the framework for the implementation of a prototype. The prototype used a knowledge base of linked open data, derived from DBpedia, on which complex network analysis were carried out. The validation of the model presented relevant recall and precision when applied to a group of 17 users. The results are promising for the use of complex network operations and concept maps for information retrieval, especially linked data. Further research should observe the demand for more interactive actions and conduct experiments in other knowledge bases.

title: methodological procedures for implementing the process of environmental management in Cuba

description: The necessary interaction between land use and the environment managemen was enacted in Law 81 and the National Environmental Strategies (EAN) since 1997, in Cuba. Several situations slowed its completion, the lack of methodological procedures that will guide the process, was one of them so the EAN of 2011-2015 and the Guidelines of the PCC ratify it as objective. In addressing this issue and the inclusion of the results of studies of hazard, vulnerability and risk and climate change scenarios currently lies of the present investigation. Given the hypothesis that: the use of inclusive and participative methodological procedures will facilitate modeling of environmental management (MOA) to provide regulations, guidelines and environmental standards to land use planning process; main objective is pursued: to propose methodological procedures for the development of the MOA and perform validation at national and municipal levels. Employees are combined theoretical and empirical methods in the development of procedures and their validation at different scales. Methodological procedures are obtained as a result, with five phases of work and validation to the development of the MOA for the land territory of Cuba, for the agricultural and livestock sectors and the MOA for the town of Yaguajay for sectors agriculture, livestock, forest, water, tourism and conservation. It was concluded in the relevance of using the proposed procedures for the preparation of the MOA, taking as a basis the participatory approach and the landscape units, as units of analysis.

title: Morphoanatomy of fruit, seed and seedling of Ormosia paraensis Ducke

description: Ormosia paraensis Ducke, known as "tento", has seeds that are used to make handcrafts and wood that is worked on by furniture makers. For forest identification and seeds technology, the information about the morphoanatomy of their fruits, seeds and seedlings is scarce. Therefore, the purpose of this study was to morphoanatomically describe the fruit, seeds and the post-seminal development of "tento". For the morphoanatomical description, the evaluations were examined by optical and electron microscopy scanning. The fruit is a nutant legume, brown to black, dehiscent and with one or two seeds of lateral placentation, being the epicarp slim, the mesocarp woody and the endocarp spongy, measuring about 4.4 cm, 3.9 cm and 2.0 cm in length, width and thickness, respectively. The seeds are bitegmic, exalbuminous and rounded with average dimensions: length of 12.36 mm, width of 9.68 mm and thickness of 8.03 mm. The "tento" seedlings have simple and alternate leaves, with tap roots and cylindrical stem, being its germination hypogeal cryptocotyledonary.

title: The formation of Greater Buenos Aires (Argentina) analyzed trough land regulations and urban legislation (1910 and 1927)

description: Abstract This paper takes part of a broader investigation which main objective is to evaluate the impact of garden suburbs and week-end houses areas developed by private enterprises within Buenos Aires´ Metropolitan Area between 1910 and 1950. To look deeply into this matter implies considering, among other subjects, those problems related to land subdivisions and State regulations. From this perspective, we will seek into land regulations and urban laws affecting the area during the first half of the twentieth Century. The main objective is to focus on the formulation and implementation of those regulations, assuming that the chaotic sprawl of the area- as defined by the Comisión Asesora del GBA in 1947- is due not to the lack of regulations but, on the contrary, to its capacity to stick into everyday practice, difficulting any process of transformation or adaptation to new ways of sprawl.

title: Sodium hypochlorite for sarcotesta remotion from papaya seeds: anatomical studies

description: Although papaya world production is high, the integument of papaya seeds, called sarcotesta, is an obstacle in the seedling production process. The aim of this work was to develop techniques to facilitate the removal of papaya seed sarcotesta for seedlings production. For that, two assays were developed. For the first one, the seeds were immersed in different concentrations of active chlorine (0, 2, 4, 6 and 8%) at ratio 600:200 seeds/mL of solution, respectively, besides the study of intact seeds and seeds subjected to the sieve method + stagnant water. For the second one, the seeds were immersed in active chlorine 2% in different ratios (10: 200; 200: 200; 400: 200 and 600: 200), and the concentration of 0% at ratio 10:200 and the sieve method + stagnant water. The effect of the treatments was evaluated by germination test and scanning electron microscopy. Sodium hypochlorite did not remove completely sarcotesta, but damaged it. In ratio 10:200 in a concentration of 2% of active chlorine for 24 hours, the embryo and the endosperm were not affected, resulting in 80% of germination, which can be an alternative to sarcotesta manual removal.

title: Criteria for implementation of a tetrazolium test in canola seeds

description: Canola is an oilseed winter plant, constituting an alternative to crop rotation. It presents socioeconomic value for the production of vegetable oil for human consumption, biodiesel and animal food formulation. The evaluation of canola seed viability is routinely performed by germination test, which can be extended for up to 14 days if it is necessary to overcome dormancy. The objective of this study was to establish criteria for conducting a tetrazolium test in canola seeds, determining viability groups. Four lots of seed were used, placed between soaked paper to hydrate for 16 hours at 20 °C. In the coloration step, after preliminary tests, the following combinations of tetrazolium salt concentration, temperature and incubation period were tested: 0.5 and 1.0% at 30 °C; 0.2, 0.5 and 1.0% at 40 °C for two, four and six hours. It was concluded that the evaluation of viability of canola seeds by the tetrazolium test is effective upon hydration of the seeds between papers for 16 hours at 20 °C, coloration by immersion in 0.5% tetrazolium solution for six hours, at 40 °C and two viability groups were established and illustrated.

title: CONSERVATION OF HELICONIA INFLORESCENCES PREVIOUSLY FERTILIZED WITH INCREASING DOSES OF NITROGEN AND POTASSIUM

description: ABSTRACT: The post-harvest of floral stems is one of the main features observed in the production of flowers for cutting, becoming a prerequisite for product quality and successful marketing. In this sense, the objective was to evaluate the conservation of heliconias inflorescences with or without renewal of the water maintenance, previously fertilized with increasing doses of nitrogen and potassium. Inflorescences of Heliconia psittacorum x H. spathocircinata cultivar Golden Torch were used and grown in open conditions in the Floriculture area at UFPI, city of Bom Jesus, Piauí State under increasing doses of fertilization with N and K. The stems were harvested in the morning, standardized and placed in containers with 500 mL of water. The design was a randomized block in factorial 4 x 4 x 2, corresponding to: i) N doses (0, 120, 180, and 240 g N hole-1), ii) K doses (0, 120, 180, and 240 g K2O hole-1), and iii) renewing the water maintenance in vase (with and without renewal) with three replicates of three stems each. Some evaluations were observed during the Study, such as: the water uptake by the flower stems; loss of fresh weight of the flower stems, dry weight of the flower stems and post-harvest longevity. The dose of 180 g hole-1 both as N and K provided the longevity of the flower stems with quality maintenance. The absorption of water by the flower stems and its dry mass after harvesting are influenced by previous fertilizer N and K. The renewal of the water maintenance also positively influence the longevity of flower stems and its a management indicated to maintain quality post-harvest.

title: Finishing of Nellore steers, castrated and no-castrated, in feedlot diet with high-grain

description: SUMMARY This study aimed to evaluate the finishing Nellore steers castrated and no-castrated in feedlot receiving high-grain diet through the nutrients intake, productive performance and economic viability of the diet. 180 Nellore animals were divided into two treatments (castrated and no-castrated), with 90 animals per treatments, with an average initial weight of 415.64kg, receiving high-grain diet with 85% corn grain and 15% supplement mineral-protein-energy. The experimental period was 63 days with 15 days for adaptation diets and 48 days of feedlot. Was no significant effect on intake of nutrients (P&lt;0.05), presenting a mean intake of dry matter (DM) of 7.60 and 7.96kg for castrated and no-castrated. Effects were observed for productive performance as a function of sex condition (castrated and no-castrated). The not castrated animals had higher (P&lt;0.05) slaughter weight, total weight gain, hot carcass weight, carcass yield and better feed conversion when compared to castrated animals finished in feedlot receiving high-grain diet. Castrated animals have a higher fat thickness that animals no-castrated, 4.80 and 3.40mm, respectively. The no-castrated animals showed profit margin lucre/animal of R$ 256.00 and R$ 202.80 for castrated. Receiving the termination of Nellore steers in a feedlot is recommended high-grain diet. The no-castrated animals showed greater weight gain and profit in the feedlot finishing system receiving high-grain diet.

title: Patrimonial imaginaries in urban reconversion processes. Puerto Norte, Rosario, Argentina

description: Abstract Progressive commercialization spaces and urban symbols are among the phenomena that characterize cities in the context of neoliberalism. The patrimony has a prominent role as a discursive tool and resource used in the urban reconversion processes, reducing conflicts and disputes. Although patrimonial is symbolically linked to urban identity, we maintain that different actors rise matrices of different transversal meanings, shared and even contradictory, forming complex patrimonial imaginaries. This work aims to investigate the patrimonial imaginary in the urban spaces under requalification process, as the case of Puerto Norte in the Refinería neighborhood of Rosario. Thus, we address discourses and representations produced by different actors - local government, real estate entrepreneurs and neighborhood associations - and analyze differences, agreements and tensions between different meanings in circulation, based on a theoretical methodological matrix focused on urban imaginaries.
