Information Specialist facing new challenges
Authors: Kiviluoto Johanna , Sinisalo Riikka
Published: August 2019

The open science and research (OSR) movement has been shaping the world of scholarly communication for a few years now. In Finland, the Ministry of Education and Culture promoted research information availability and open science through the Open Science and Research Initiative. As a part of this initiative, an evaluation of the openness of Finnish research organizations was completed. The first evaluation indicated that OSR functions needed clearer guidelines and a coordinating unit to further improve the cultural maturity in Lahti University of Applied Sciences (LAMK). Furthermore, the scholarly publishing activities also needed a new home base due to organizational changes. As the information and library services had the basic understanding of scholarly publishing, different publishing channels and responsible conduct of research, it was decided that the library takes on these responsibilities.

For the new challenges, the traditional information specialist skills set needed updating. New skills were acquired via both formal and informal learning, benchmarking and trial-and-error. These new skills were immediately put to use in LAMK by creating a new open access publishing platform, organizing workshops and lectures for the staff and creating organizational guidelines for open RDI practices. The next organizational maturity evaluation ranking round proved the library’s new expertise, as LAMK climbed two levels up, being the second highest university of applied sciences in Finland.

As for the role of the information specialists, the new role as OSR experts have opened up new possibilities within the organization. They are now seen more as possible partners in different RDI activities, participating in project work and further developing the way openness is being carried out in all aspects of RDI and teaching. The paper offers a case example of how library professionals can diversify and update their skills pool and shape the future of their profession.
“Students Can Write!”
Authors: Brodersen Randi Benedikte , Kavli Solveig
Published: August 2019

One purpose of this article is to shed light upon the concept of voice in writing, related to genres and sources in humanities. Another purpose is to participate in the academic discussion on voice. We want to raise awareness about the use of voice, in general, among students and supervisors. We want to inspire and motivate students to voice their texts explicitly and naturally – by using different genres and by entering into dialogue with central sources. Such sources can be used to create new meaning and for sense making, but they do not carry a given answer (Dervin, 1999; Holliday & Rogers, 2013).

The variation and complexity of voice is present in the variety of sources students find and use, such as articles, textbooks, dissertations, interviews, films, pictures, etc. Voices are explicit or implicit in all kind of sources used. Voices emerge as authoritative and experienced within academia, for instance in textbooks and articles. Voices may be creative and inviting. Some are attractive and believable, others hesitant or uncertain, as voices in many texts written by students.

Students, at all academic levels, express insecurity when working with academic writing and genres. However, by analysing and practicing different academic genres and by attending to voice(s) in others’ texts, students are empowered to explore genres and sources and to voice their own texts. By using and entering into dialogue with various sources, students make choices about how to present and interact with sources. In these ways, students develop their voices and improve their texts.

Our theoretical point of departure deals with voice, dialogue (Elbow, 2007; Bakhtin, 1986) and the use of sources combined with the search for information (Dervin, 1999; Holliday & Rogers, 2013). We analyse and compare two examples of the use of sources in academic texts, in order to show how texts representing two genres, use voices and sources in different ways. We present supervisors’ guidance strategies, representing supervisors’ voices. We – and supervisors – mention students’ general challenges with academic writing. Finally, we present dialogic strategies and propose a new dialogic strategy. This new strategy combines and unites reading and writing in different genres, drawing on and entering into dialogue with central sources, with different and clear ways of voicing; explicit and implicit voicing. Our dialogic strategy – and other intended dialogic strategies – can be used by students and all supervisors who assist students in writing, when dealing with voice(s) and sources.
Fifteen minutes of data
Authors: Petersson Jonas , Hedbrant Moa
Published: August 2019

The concept Fifteen minutes of data (Datakvarten) started during spring 2017. We saw a growing need to engage librarians with data, research data and related issues, and with the creation of our digital lab we got the final incentive. However, it is a new area to many and can be complex, so there was some hesitation and reluctance amongst our colleagues. This initiative aimed to integrate it in a nice and easy way to our daily work. We wanted to develop a competence on the subject within our whole unit but needed to fit the learning process into already busy schedules.

The fifteen minutes of data happened on our regular unit meetings, occurring every other week. Workshop sessions were mixed with lectures and seminar methods to engage everyone in different ways. We tried to follow a logic path in pic of topics, to start with the basics and step up the complexity bit by bit. Topics could be about what data really is, PSI (Public sector information), visualisation, data literacy and data formats. The year ended up with a quiz to repeat the most important. We had a logotype and used a special jingle to introduce each session, which was much appreciated.

 It was important to meet the whole unit, with different previous knowledge and interest. Fifteen minutes is not a long time, but we can conclude that it was worth the effort and planning time – it went well and the concept will continue throughout 2018. With the presentation we want to highlight the concept and encourage others to try it, but also raise questions about what every librarian should know and master about data. What trends do you see? What lies ahead?
Bringing Research Data Management to Academic Libraries
Authors: Hüser Falco Jonas , Lavanchy Paula Maria Martinez
Published: August 2019

Modern research institutions are faced with rapidly increasing challenges imposed by data-driven science and have to deal with new demands from funding agencies and publishers regarding open access to research data as well as from the Code of Conduct for Research Integrity on reproducibility of results. In reply to these requirements, the Technical University of Denmark (DTU) has adapted a two-fold strategy of bringing together decision-makers, relevant support units in the administration and researchers from all departments for the task of designing policies and services in alignment with common traditions in the different fields of research. This mixed “bottom-up” / “top-down” approach ensures that best practices  for research data management can be implemented in the daily routines of employees in a practical and supportive way while ensuring that the researchers can live up to all relevant administrative, legal and ethical standards. 

In this presentation, we will show how DTU Library has taken over a central position in this process by investigating the needs and demands from researchers in the different fields, drafting procedures and guidelines for research data management and establishing support functions and training for all aspects  of the data life cycle. Within this new and complex area, the creation of new positions for research data management at the library in addition to an optimal utilization of existing resources and knowledge has been crucial for building up the necessary expertise and thus for the success of the strategy.

“A body shape index” and its association with arterial hypertension and diabetes mellitus among Brazilian older adults: National Health Survey (2013)
Authors: Nascimento-Souza Mary Anne , Lima-Costa Maria Fernanda , Peixoto Sérgio Viana
Published: August 2019

The aim was to evaluate the separate and joint association of abdominal adiposity indicators (a body shape index - ABSI, waist circumference - WC, waist-to-height ratio - WHtR) and body mass index (BMI) with arterial hypertension and diabetes mellitus, in Brazilian older adults. Data from the 2013 Brazilian National Health Survey (PNS 2013) were used for the population aged 60 years or older (10,537 older adults). Arterial hypertension and diabetes mellitus outcomes were self-reported and the following anthropometric indices were evaluated by direct measurement: a ABSI, BMI, WC and WHtR. Associations were assessed by logistic regression, with adjustments for confounding factors. The results of this study evidenced a higher strength of association between the report of arterial hypertension and diabetes mellitus with BMI, WC and WHtR in the Brazilian population of older adults in separate analyses, when compared to ABSI. When adjusted for BMI, ABSI showed a greater strength of association with the outcomes, but it was not superior to the performance of WC and WHtR. Considering the lower strength of association, in separate and joint analyses, between the new index (ABSI) and the chronic conditions assessed, BMI, WC and WHtR probably remain as useful indices in public health, at least in relation to arterial hypertension and diabetes mellitus in Brazilian older adults.

Authors: Werlang Nathalia Berger , Rossetto Carlos Ricardo
Published: August 2019

Abstract The objective of this study is to analyze the relationships between learning orientation, organizational innovativeness, and organizational performance in hotels and lodging establishments in Santa Catarina, Brazil. The methodological procedures employed to achieve this objective are grounded in the survey method and the study is of a descriptive nature. Structural equations modeling techniques were used to assess relationships between constructs and the final sample comprised 162 managers of hotels and lodging establishments in Santa Catarina. The main findings are as follows: (1) learning orientation has a positive and direct influence on organizational innovativeness; (2) organizational innovativeness does not significantly affect organizational performance; and (3) learning orientation does not have a positive relationship with organizational performance. It is therefore concluded that management of hotels and lodging establishments should take a proactive approach to their human resources, to raise employee awareness about actions that improve organizational learning and innovativeness, so they can have a positive impact on organizational performance.
An application of Earned Value Management (EVM) with Monte Carlo simulation in engineering project management
Authors: Bonato Felipe Kahan , Albuquerque Andrei Aparecido de , Paixão Michel Augusto Santana da
Published: August 2019

Abstract The fast changes in the Market make companies increasingly focus on project structures. A project differs from a routine activity because it is unique and must be managed and structured to provide expected benefits at no greater cost than anticipated. Therefore, it must be planned and controlled by identifying the deviations between the planned and the accomplished. In order to provide this monitoring, Earned Value Management (EVM) has been increasing accepted. In addition to showing indicators of progress, EVM can be used to forecast the project's final costs through simulated scenarios. This work aims to integrate and apply EVM with Monte Carlo simulation to predict the final costs of three detailed engineering projects, evaluating the performance of the model and the projects, in each specific case study. The results of the three projects simulations were evaluated in a qualitative and comparative way, showing that the integration between the tools generates useful forecasts for project management.

Published: August 2019

Resumo Neste trabalho avaliou-se o potencial reativo de adições de resíduo de cerâmica vermelha (RCV) e de concreto de RCD, além de fíler calcário para referência. Avaliou-se o potencial pozolânico das adições por índice de atividade pozolânica (IAP) com cal, índice de desempenho (ID) com cimento, teor de hidróxido de cálcio fixado no Chapelle modificado e caracterização por difratometria de raios X (DRX). Os resultados mostram que o RCV atendeu aos requisitos químico-físicos para pozolanas, IAP com cal, ID com cimento e apresentou singelo halo amorfo na DRX indicando baixa reatividade, porém o material não atendeu requisitos mínimos no ensaio de Chapelle. O pó de concreto, apesar de não ser uma pozolana, foi submetido aos ensaios de IAP com cal e ID com cimento e apresentou resistências à compressão abaixo das mínimas prescritas nas normas pertinentes. Este material também apresentou halo amorfo na DRX, atribuído ao C-S-H da pasta de cimento hidratada.

Published: August 2019

Resumo Nesse trabalho avaliou-se a influência da adição do resíduo da produção de TiO2, minério não reagido (MNR), nas propriedades de argamassas de revestimento. Para isso, avaliaram-se as propriedades de argamassas mistas (cimento Portland branco e cal) com adições de 0%, 5%, 10% e 15% de MNR, em relação à massa do cimento. As argamassas foram avaliadas quanto ao tempo de pega, reologia (flow table, squeeze flow e reometria) e propriedades físico-mecânicas, além de ensaios de aderência à tração e pipeta de Karsten. Os resultados obtidos indicaram retardo na pega e perda de plasticidade com a incorporação do MNR. Ademais, o resíduo não influenciou de forma significativa as propriedades físico-mecânicas das argamassas. Concluiu-se que o MNR pode ser incorporado às argamassas de revestimento, apresentando propriedades dentro dos requisitos normativos. Contudo, para a viabilização da utilização do MNR em argamassas, ressalta-se a necessidade de estudos de lixiviação, solubilização e de durabilidade dessas argamassas.

Published: August 2019

Abstract This study aimed at assessing the potential uses of alluvial clayey materials from Batouri. Their mineralogical, chemical and some physicomechanical characteristics are presented with some characteristics of fired bricks at 900, 950, 1000, 1050 and 1100 °C. The raw materials consisted of kaolinite, quartz, K-feldspars, anatase, and goethite. The phases formed during the firing process were mullite, quartz, hematite, and anatase. The linear shrinkage increased with firing temperature and remained <12% while water absorption decreased and remained <25%. Flexural strength increased due to the formation of dense phases (especially mullite) and, except for one sample, was at least 2 MPa. The SEM micrographs showed cracks that accounted for overall moderate mechanical responses. For firing above 1000 °C, the flexural strength of the three samples makes them usable as raw materials for roofing tiles manufacturing if the convenient amendment is done. The overall properties highlighted that all the studied materials are usable for brick manufacturing.

Published: August 2019

Abstract Some known self-compacting concrete (SCC) mix-designs are based on the lowest void content as a purpose of an ideal packing. However, a composition with a lower void content is not a guarantee of good synergy between the largest and smallest grain in the fresh state. The purpose of this study was to identify and evaluate different packing parameters in the aggregates gradations that influence on the self-compactability. Nine aggregates combinations (4 binaries, 4 ternaries and 1 quaternary) were used for determination of nine gradations. Tests as slump-flow, L-box and V-funnel were used. The distribution coefficient (q) was determined by the Alfred model. The results showed that not all values of q (between 0.201 and 0.253) attended the values given for SCC, and the gradations with the lowest difference among the coarse and fine particles, higher void content, continuous distributions and 50% of coarse aggregates had better performance.

ABSTRACT Lactobacillus acidophilus NCFM (L-NCFM) was microencapsulated via co-extrusion technique with mannitol. Optimization of coating material, locust bean gum (0% to 2%, w/v) and prebiotic, mannitol (0% to 5%, w/v) was tested on bead size and microencapsulation efficiency. L-NCFM cells microencapsulated in three different forms were tested in simulated gastric juice (pH 2.0) and simulated intestinal juice (pH 7.5) and storage test at 4 °C and 25 °C for 4 weeks. 0.5% (w/v) locust bean gum and 3% (w/v) of mannitol are the optimal concentrations to produce bead size of 570 µm, microencapsulation efficiency of 96.81% and cell count 8.92 log CFU/mL. Microencapsulation of L-NCFM with mannitol protect cells better in acidic environment. The viability of encapsulated L-NCFM with mannitol at 4 °C throughout the storage period for 30 days ranged from 8.62 log cfu/mL to 6.80 log cfu/mL, which met the minimum required for probiotic (106CFU/mL).

Published: August 2019

ABSTRACT The benefits of mycorrhization occur with the growth of hyphae in colonized roots by promoting an increase of the contact surface which improves the initial growth due to a better absorption of water and nutrients. The objective was to evaluate the effect of arbuscular mycorrhizal fungus Rhizophagus clarus inoculation over the initial development and nutritional response of six genotypes of Coffea arabica L. Six genotypes of Coffea arabica L. were used (MGS Aranas, H29-1-8-5, Red Catuai IAC 144, IPR 100, Catigua MG2, Paraíso H 419-1) and with arbuscular mycorrhizal fungus - AMF: Rhizophagus clarus and without the application of the fungus. For the production of coffee seedlings, seeds were placed to germinate in plastic trays with sterile sand. After germination, 10 seedlings of each genotype were transferred to 0.120 dm3 polyethylene tubes with substrate. Then the inoculation of five seedlings of each genotype with the AMF R. Clarus was performed. When the seedlings with and without inoculation with the AMF presented six pairs of leaves they were transplanted to 13-liter pots containing soil (Dystrophic red-yellow latosol). The inoculation favored the initial growth of the coffee plants and its intensity varied according to the genotypes. The genotypes H 29-1-8-5, Red Catuai IAC 144 and Catigua MG 2 were the ones that presented higher shoot dry mass, root dry mass, total dry mass and accumulation of P, in relation to MGS aranãs, Paraiso H 419-1 and IPR 100, so they are the most promising to be inoculated with the arbuscular mycorrhizal fungus.

Published: August 2019

Abstract: Despite the great impacts of invasive wild pig (Sus scrofa) to natural ecosystems, habitat use by this species in the neotropics remains poorly studied. Here, we investigated the effects of local habitat and landscape covariates (vegetation types, running watercourses and roads) on occupancy patterns of wild pig in the Atlantic Forest of southern Brazil. We used single season occupancy modeling to estimate detection (p) and occupancy (ψ) probabilities, using 8-day camera-trap monitoring of 100 sampled sites. The cameras detected wild pig in 64 sites (naïve occupancy = 64 %). The four best models explained 72.7 % of the occupancy patterns, and the top model (with "water" variable) had a weight of 28.5 %. Even though none of the tested variables had high explanatory power of wild pig occupancy, the water variable had a negative effect trend (β = -1.124; SE = 0.734), with 59 % of occupancy when water was present and 82 % when it was absent around the sampling sites. Vestiges of the presence of wild pig in different vegetation types revealed that they used plantations of Pinus sp., native forests, and corn and oat crops. The occupation pattern shows that wild pig are generalist at our study site at the Atlantic Forest being found everywhere, raising ecological and economic concerns about the high potential negative effects of its invasion.

Dessas funções, a de passado do passado foi investigada em perspectiva variacionista, sendo a forma simples condicionada, de modo recorrente, por terceira pessoa discursiva e ausência de modificador verbal. Também motivam a forma simples os fatores gênero textual efemérides, verbo irregular e oração coordenada.
O emprego do modo subjuntivo nas orações adverbiais no português popular do interior do Estado da Bahia: um estudo sociolinguístico
Authors: Lucchesi Dante , Meira Vivian
Published: August 2019

RESUMO Desenvolveu-se uma análise sociolinguística da variação no emprego do subjuntivo nas orações adverbiais no português popular do interior do Estado da Bahia. O encaixamento da estrutura linguística revelou que as formas do subjuntivo são mais frequentes em duas situações: (i) uma de base morfológica; (ii) outra de base semântica. No plano do encaixamento social, observou-se um quadro de mudança em progresso, em que o subjuntivo é mais frequente na fala dos mais jovens, o que corrobora a hipótese de que a variação no uso das formas marcadas do subjuntivo teve sua origem no processo de transmissão linguística irregular.
THE IMPACT OF INTANGIBLES OF GERMAN, ENGLISH AND PORTUGUESE COMPANIES: FROM 1999 TO 2016
Authors: VASCONCELOS TIAGO , FORTE DENIS , BASSO LEONARDO F. C.
Published: August 2019

ABSTRACT Purpose: The present paper is aimed to investigate the relationship between intangible assets, macroeconomic environment and market value of German, English and Portuguese public companies from 1999 to 2016. Although the IAS 38, assigns value to intangible assets, there is a gap between accounting and the market need. This gap is given by accounting conservatism in the accounting of intangible assets and by their difficult measurement. The verification of the impact of the intangibles on the company’s market value is done through the methodology proposed by Gu and Lev (2011), using proxies such as CDS, Libor and Euribor and sensitivity tests. IDE is expected to reflect intangible capital and create shareholder value. This study seeks to interpret the contribution of intangibles and to forecast their impact on the market. Originality/value: The theme of evaluation of intangible assets has been approached in several ways. Its relevance lies in the need to establish methods for its measurement. Design/methodology/approach: The methodological approach is quantitative research with panel data using Stata-15. The database is the Capital IQ with public companies, listed in Germany, England, and Portugal from 1999 to 2016, with annual frequency. Findings: The results suggest that the comprehension value has a positive and significant relationship with the market value of the companies and that the intangible capital and the intangibles-driven-earnings are positively related to research and development expenses and general, administrative procedures.

Published: August 2019

ABSTRACT Objective To investigate the prevalence of Body Image distortion and dissatisfaction and evaluate the associated factors in incarcerated women in a closed regime. Methods Cross-sectional observational study, conducted with female inmates (n=107) in Rio Grande do Norte, Brazil. Personal sociodemographic data were collected through an interview, and the height and weight were measuredto obtain the body mass index. Body image was assessed using a scale of silhouettes fi gures for Brazilian adults. Prevalence Ratios with their respective 95% Confi dence Intervals and Bland-Altman method were used in thestatistical analysis. Results A total of 83.3% of the participants were affected by body image distortion and 91.6% by body image dissatisfaction. More than a half (58.9%) wanted a lower Body Mass Index (9.01±5.25Kg/m2), however, 32.7% wanted to increase the body size (6.43±4.34Kg/m2). The sociodemographic characteristics, nutritional status (PR=0.99; 95%CI:0.89-1.11), and the time of imprisonment (PR=1.06; 95%CI:0.94-1.19) were not associated with Body Image dissatisfaction. No associations were observed between body image distortion and the time ofimprisonment (PR=1.17; 95%CI:0.96-1.42) or nutritional status (PR=1.10; 95%CI:0.89-1.36). Conclusion Most female inmates were dissatisfied with their bodies and distort their body image, indicating the need for these aspects to be included in the health promotion actions in the prison system.
Maize: Key agricultural crop in food security and sovereignty in a future with water scarcity

Published: August 2019

ABSTRACT The objective in this review was to discuss the importance of maize currently and the crucial role it may play in the future for food production in scenarios of water shortage, as well as the importance of conserving its landrace cultivars, which have a considerable portion of the reserve of genetic variability. Maize plants, when exposed to water deficit, may develop physiological, morphological, biochemical and anatomical adaptation mechanisms. With the aid of genetic improvement, characteristics that impart tolerance are fixed in plants through conventional methods. In this context, ‘Tuxpeño Sequia’ cultivars were developed in Mexico, while in Africa, one of the most important strategies was the development of ‘DT’ (Drought-tolerant) cultivars. In the United States, one of the most important processes was the development of PionerAquamax® hybrids, while in Brazil, it was the development of cultivars with the ‘Maya Latente’ gene. Through genetic transformation, the hybrid ‘MON 87460’ was developed. However, it should be mentioned that, for a cultivar to be well accepted by producers, besides having one or more adaptation characteristics, it must have a high grain yield. Biotechnological tools such as the use of molecular markers, genetic transformation, and modeling through bioinformatics, associated with conventional selection, will be fundamental to guarantee the advancement of water deficit tolerance in maize.

ABSTRACT This study aimed to evaluate the contents of macronutrients (NPK and S) and the growth of ‘Potiguar’ corn fertigated with human urine, cassava wastewater and their associations with NPK. The experiment was set up in greenhouse located on Campus I of Universidade Federal de Campina Grande. A completely randomized experimental design was used, consisting of eight treatments, corresponding to fertigation with mineral fertilizer NPK formula; organic, composed of yellow water, cassava wastewater and human urine associated with cassava wastewater; organomineral, composed of human urine associated with phosphorus and potassium, cassava wastewater associated with nitrogen and phosphorus and human urine associated with cassava wastewater and phosphorus, with five repetitions. At 50 days after sowing (DAS), plants were evaluated for the leaf NPK and S concentrations and growth variables: number of leaves, plant height, stem diameter, leaf area, fresh and dry mass of leaves, mass of stem and shoots. Nitrogen and phosphorus concentrations and the growth variables number of leaves, plant height, fresh and dry mass of leaves, mass of stem and of shoot were influenced by fertigation with human urine, cassava wastewater concentrations and their associations with NPK. In the leaves of corn cultivar Potiguar the accumulated concentrations of N, P and K, at 50 DAS, varied in the sequence N > K > P. Human urine has potential as source of N in fertigation of corn and cassava wastewater can be used if associated with other sources of nutrients.

ABSTRACT Salinity is one of the main agricultural problems faced, and may negatively influence plant development. However, studies have shown that in protected environments and under the application of organic fertilizers, deleterious effects are mitigated. In this context, the objective of this study was to evaluate the effects of irrigation water salinity on mineral nutrition in noni plants grown in two environments and bovine manure application. The statistical design was a randomized block design arranged in split-split plot scheme, with five repetitions. The plots consisted of the cultivation environments (greenhouse and open field), the subplots formed by salinity levels of irrigation water (ECw: 0.3, 1.5, 3.0, 4.5 and 6.0 dS m-1), and the subsubplots were represented by the absence and presence of organic matter, with experimental unit consisting of three pots totaling 300 pots. The nitrogen, potassium, calcium, magnesium, sodium and chloride concentrations were determined in plant leaves. It was verified that the foliar concentrations of Ca2+, Mg2+, Na+ and Cl- and the ratio Na/K was increased with increasing salinity of the irrigation water, being the largest increments observed in the open field. Organic matter is not much relevant in attenuating the deleterious effects of irrigation water on the concentration of leaf nutrient in noni plants. The maintenance of lower values of Na/K ratio in the treatment with organic matter is a positive factor that can attenuate the effects of salt stress on cell metabolism.

Published: August 2019

ABSTRACT This study aimed to dry ‘bacaba’ (Oenocarpus bacaba Mart.) pulp under different thermal conditions, fit different mathematical models to the dehydration curves, and calculate the diffusion coefficients, activation energy and thermodynamic properties of the process. ‘Bacaba’ fruits were meshed to obtain the pulp, which was dried at temperatures of 40, 50 and 60 °C and with thickness of 1.0 cm. Increase in drying temperature reduced the dehydration times, as well as the equilibrium moisture contents, and drying rates of 0.65, 1.04 and 1.25 kg kg min-1 were recorded at the beginning of the process for temperatures of 40, 50 and 60 °C, respectively. The Midilli’s equation was selected as the most appropriate to predict the drying phenomenon, showing the highest R2, lowest values of mean square deviation (MSD) and χ2 under most thermal conditions, and random distribution of residuals under all experimental conditions. The effective diffusion coefficients increased with increasing temperature, with magnitudes of the order of 10-9 m2 s-1, being satisfactorily described by the Arrhenius equation, which showed activation energy (Ea) of 37.01 kJ mol-1. The drying process was characterized as endergonic, in which enthalpy (ΔH) and entropy (ΔS) reduced with the increment of temperature, while Gibbs free energy (ΔG) was increased.

Abstract Introduction Root-scaling procedures on the root surface show to increase root surface roughness during instrumentation. The use of a prophylactic paste reduces the roughness. Objetive This study evaluated the influence of prophylaxis paste on the surface roughness of root dentin after hand instruments (HI), ultrasonic scalers (US) and rotational instruments (RI) were applied to root surfaces. Material and method Fifty bovine roots were prepared and randomly divided into 10 groups (n=5) in which instrumentation with HI, US, or RI was carried out with or without prophylaxis using either conventional or 3% hydroxyapatite paste; additionally, a control group without treatment was included. The Ra and Rz roughness values were measured using a perfilometer. The morphological aspects of the root surfaces were analysed qualitatively by scanning electron microscopy (SEM). Data were analysed using two-way ANOVA followed by Tukey’s test (α = 0.05). Result The scaling method and the prophylaxis procedure significantly influenced (p < 0.05) root surface roughness. Treatment with US and prophylaxis with 3% hydroxyapatite paste resulted in lower values of Ra (0.14 μm ± 0.02 μm) and Rz (0.89 μm ± 0.18 μm) compared to the other groups. SEM analysis showed smoother and more homogeneous surfaces in the groups with prophylaxis compared to the groups without prophylaxis. There were no substantial differences between the results of applying different pastes. Conclusion The prophylaxis procedure performed with the experimental paste containing 3% hydroxyapatite reduced the roughness of root surfaces treated with HI, US and RI at the same level as the conventional prophylactic paste.

Published: August 2019

ABSTRACT The fringed leaf frog, Cruziohyla craspedopus is rarely sampled in the Brazilian Amazon, probably due to low detection probability associated with its arboreal habit. The knowledge about the species’ distribution stems from successive additions of occasional occurrence records, which indicate that the species is widely distributed throughout Amazonia. We present new occurrence records to update the geographic range of the species, which is hereby extended 224 km to the northeast. We also present morphological data from collected specimens and discuss the updated range from the geographic and ecological points of view. We show that the range of the leaf frog crosses several main tributaries along the southern bank of the Amazonas River, although the species occurrence is apparently limited by a minimum tree cover of 70%.

ABSTRACT Objective: to construct and validate a high fidelity clinical simulation scenario on nursing care to colostomy patients. Method: descriptive study of construction and validation of the appearance and content of a high fidelity clinical simulation scenario referring to nursing care for colostomy patients. To guide the elaboration of the scenario, a study was carried out in the literature on nursing care for the colostomy patient in the hospital environment. The scenario was constructed according to the items proposed by Fabri, based on the Bloom’s Taxonomy. For the selection of the nine experts, the criteria proposed by Fehring were used. The scenario, after being structured, was tested by a group of students from the 3rd and 4th years of graduation in nursing in a clinical simulation laboratory of a public university. It was considered 80% level of agreement. Results: in the validation of the scenario, all the experts agreed with the proposed items, suggesting the inclusion of some references, book chapters, skills training, preparation of reading material and checklist follow-up of participants. This scenario test allowed the identification of relevant contributions for adjustments of the simulated activity and allowed to test the debriefing with the support of the checklist. It was also evidenced the need to include information in the patient medical record and to increase the time of development of the scenario to solve the proposed objectives. Conclusion: the results show that for practical simulated well defined and successful are required to careful preparation, validation and prior testing of the planned activities.

Published: August 2019

ABSTRACT Objective: to explore the perception of harms and benefits of marijuana use and adolescents’ intention to use within the context of regulatory changes. Method: a multi-centric quantitative cross-sectional survey. The survey incorporated two public co-educational secondary schools from which a total of 268 (133 males; 135 females) adolescents from age 15 to 17 were studied. Convenience sample was used to obtain the participants from forms 3 through 5 and administer consent forms and questionnaires. Results: From the sample studied most adolescents reported that they do not use marijuana. The study found an association between adolescents’ perception of harms and benefits of marijuana and marijuana use. It also highlighted that most adolescents stated that marijuana should be used for medical and/recreational purposes. Conclusion: further research is needed incorporating a larger sample of schools to establish conclusive statements however these findings suggest that school demand reduction strategies should seek to be as comprehensive and tailored as possible when addressing adolescents.

Abstract This study evaluated Bacaba powder produced in a spouted bed as a source of bioactive compounds and high energy value. The conditions influencing the drying process parameters (yield, moisture level, phenolic and anthocyanin retention) as well as simultaneous optimization (optimal conditions) of production were also considered. Drying was most efficient at 75 °C using maltodextrin concentrations above 20.0% (w/w). Higher anthocyanin retention (92.52%) at 65 °C (p = 0.0003), and a maltodextrin concentration of 20.0% (w/w) resulted in high retention of phenolics (95.38%). Accordingly, the operations tested under the desirability function (68 °C, maltodextrin concentration of 21.7% w/w, and air velocity of 1.3 × minimum spouting velocity (Vjm) m s-1) resulted in a process yield of 55.04% and the dry basis (d.b.) composition results were: total phenolics (376.43 mg GAE 100 g-1), energetic value (612.64 kcal 100 g-1), lipids (47.74 g 100 g-1), carbohydrates (27.79 g 100 g-1), protein (15.10 g 100 g-1), and dietetic fiber (8.45 g 100 g-1). The high solubility (92%), flowability (14%), energy, and bioactive characteristics of Bacaba powder suggest the potential for many applications, such as development of dietary supplements, high-energy drinks, milk-based and instant products, and bakery products.

Authors: Rusch Fernando , Ceolin Guilherme Bordignon , Hillig Éverton
Published: August 2019

ABSTRACT Bamboos are fast-growing plants, with outstanding physical-mechanical characteristics that may be chiefly ascribed to the features and dimensions of their main structural element: their fibers. This study aimed to perform a dimensional description (length, width, lumen diameter and wall thickness) and depict the indices and technical coefficients of fibers of bamboo species that occur in Brazil, through a bibliographical survey. The results showed that the basic density in test stem-specimens of the surveyed species varied between 0.451 g cm-3 and 0.780 g cm-3, what revealed a great variability among them. The average values observed for the fiber dimensions were 2.29 mm for length, 16.4 µm for total width, 6.4 µm for wall thickness and 3.5 µm for lumen diameter. From these data, it was possible to estimate indices and technical coefficients that support good physical-mechanical characteristics of bamboo in the several studied species.
