title: Temporary immersion biorreators: efficient technique for the propagation of the ‘Pircinque’ strawberry

description: Abstract The in vitro propagation technique via temporary immersion bioreactors is a tool that, through the culture in a liquid medium, allows an increase in the efficiency of seedling production. Several researches with the strawberry crop have shown greater efficiency of the system compared to the conventional process of micropropagation in solid medium. In this sense, the objective herein was to establish a protocol of multiplication and rooting of the ‘Pircinque’ strawberry, in temporary immersion bioreactors. Two distinct and independent studies were carried out, characterized by the multiplication and rooting stages of strawberry explants, newly introduced and registered in Brazil. Two culture media (MS and KNOP) were studied and, as a control treatment, the growth of the explants in solid culture medium was evaluated with the addition of 5 g L-1 of agar. Different immersion times of the culture medium were explored: five or eight times a day, for 15 minutes. The study was composed of the culture medium and immersion time factors, as well as the control (solid) treatment. It was verified that the use of temporary immersion bioreactors system is an efficient technique for the multiplication and rooting of explants of strawberry cv. Pircinque, when compared to the conventional method of micropropagation with the use of solid culture medium, making it possible to optimize the production of seedlings in biofactories. The MS liquid medium, in contact with explants of ‘Pircinque’ strawberry five times a day, increased the growth of the aerial part and the root system.

title: Responsabilidade Social nas Agroindústrias Canavieiras no Brasil

description: Abstract: The objective of this research is to identify which of the economic, environmental or social dimensions exerts greater influence on the socially responsible behavior of the sugarcane agroindustry in Brazil. In order to do that, a theoretical survey was carried out to identify the origin, evolution and conceptualization of Social Responsibility, besides characterizing and presenting the relationship of the sugarcane agroindustry with the research theme. This research adopted as methodological procedure explanatory and quantitative research. As a research instrument, a questionnaire was applied, based on the theoretical basis and guidelines provided by the Global Reporting Initiative, applied to a universe of 184 sugarcane agroindustry (individual or group of companies), obtaining a return of 128 questionnaires. In order to attest the hypothesis, the structural equation modeling, applied through the SmartPLS, was used. The results demonstrate there is a positive influence of the economic, environmental and social dimensions in the CSR. When comparing the three dimensions, due to the fact that sugar-alcohol activity is very sensitive to environmental issues, in addition to the regulations that guide industrial processes, statistically the environmental dimension was not significant. On the other hand, the social dimension, due to historical, activity and administrative characteristics, exerts major influence in CSR.

title: Time allocation, importance of activities and staff profi le in academic libraries from a business processes standpoint

description: Abstract The aim of the study was to investigate, from the business processes standpoint, the time allocated by academic libraries in their different activities, the importance attributed by their managers to the activities performed, and the staff profile. Academic libraries have an important role in providing the informational needs of teaching and research, through its functions of formation and development of collections, bibliographic control, information delivery and management. The process management collaborates to the achievement of the organization strategic goals. It is considered a system of activities integrated in business processes, which may be an excellent tool for evaluating and implementing improvements in academic libraries. To fulfill their role, the libraries of Brazilian higher education institutions have a workforce composed of two profiles: librarians and non-librarians. The survey is bibliographical, descriptive and qualitative. The sample consists of 14 libraries of a federal institution of higher education. The activities inherent to the libraries were structured in processes and sub processes, and the percentage of time spent in them, their importance and the profile of the executing agents involved were determined. As a result, time, importance, and profile data were linked to the processes and sub processes, in order to investigate their association.

title: Business metadata: Representation of business processes’ information

description: Abstract Metadata are considered fundamental elements in Library and Information Science and its and its characteristics, applications and typologies is been studied extensively by researchers in the area, mainly since 2000. This article aims to bring a new typology of metadata to Brazilian Library and Information Science studies, the so-called business metadata. Business metadata are the business context behind data and can be found in any business process in the different sectors of diverse institutions. Considering the lack of literature about this kind of metadata in Library and Information Science, using literature research, this paper aims to bring its concept, applications, examples and studies about business metadata. This research is theoretical and conceptual nature, characterized as exploratory research. Business metadata could be observed as very pertinent to the concepts and principles of Library and Information Science, which allows concluding that this concept can and should be studied by the area, mainly in the studies related to Information Architecture, Information Systems and Information Retrieval.

title: Effectiveness of a rapid soil incubation method for determining potential acidity of soils in Rio Grande do Sul, Brazil

description: ABSTRACT: Potential soil acidity can be measured by two methods in the states of Rio Grande do Sul (RS) and Santa Catarina (SC): solution SMP or solution TSM (Buffer Santa Maria). Calibration of these methods is done by incubating soils for long periods (180 days) of CaCO3. The hypothesis of this study is that it is possible to reduce the incubation period in soils by using a soluble base such as calcium hydroxide. The study aimed to estimate potential acidity in a group of soils by moist incubation with Ca(OH)2 (short) as an alternative to the typical method with CaCO3 (long) and relate to the values estimated by the equation used by the Soil Chemistry and Fertility Commission of Rio Grande do Sul and Santa Catarina (CQFS-RS/SC; 2016). Ten soils with sandy texture and low organic matter content were collected at 0-20cm in the Campanha Gaúcha region of the state of RS and incubated for 180 days with doses of CaCO3 equivalent to 0, 25, 50, 75, 100, 125 and 150% of the lime requirement estimated by the solution TSM to raise to pH 6.0. Soils were also incubated for 4 days in an oven at 35ºC with 0.22mol L-1 Ca(OH)2 at doses equivalent to CaCO3. Short incubation of the soil with Ca(OH)2 may substitute long incubation with CaCO3. Also, estimating potential acidity using the equation of the CQFS-RS/SC (2016) overestimated potential acidity in soils with solution TSM pH values lower than 6.0 in this study.

title: Henrique Dumont: how a traumatic brain injury contributed to the development of the airplane

description: ABSTRACT The life and death of Henrique Dumont (1832-1892) is little known, being usually remembered as Alberto Santos-Dumont's father. This report describes the history of this Brazilian engineer, also known as the King of Coffee, who achieved enormous business success and fortune in the late nineteenth century. In 1890, during the inspection of his farm, the world's largest coffee plantation at that time, he fell from a carriage, which left him a hemiplegic. This forced him to sell the farm and move to France for treatment. Before his death two years later, he gave his 18-year-old son bits of advice, and distributed his inheritance, which allowed Alberto to study in Paris and finance his experiments that would culminate in the development of the airplane. The diagnostic and therapeutic possibilities are also discussed.

title: Zooplankton community attributes in an oligo-mesotrophic reservoir: A comparative study of two sampling strategies

description: Abstract Studies of the limnetic zooplankton in Brazilian freshwater have been done using several sampling strategies which are frequently associated to personal preferences, system constraints and objectives of the studies. It is known that a better sampling technique exists for each group of investigated zooplankton. So, the challenge is to provide a good sampling method for all groups at once. Regarding this theme we are contributing by pointing out the merits and demerits of two collecting methods of zooplankton widely used in many studies in Brazilian reservoirs to clarify the information about communities’ structure in past published and non-published biological data and also find a more useful sampler for future studies. Two simultaneous strategies were used with a 68μm-plankton net: filtration of water collected at sub-surface by bucket and vertical hauls throughout the euphotic zone. A total of 133 taxa was found with both strategies. Rotifers (69 taxa) comprised the group with the highest richness, followed by protozoans (31 taxa), cladocerans (30 taxa) and copepods (5 taxa). Paired t-tests showed significant difference for richness despite none for density in whole period. Spatially, sampling strategies differed in abundance and composition of zooplankton at most sites sampled (except for L1- shallowest site and L4 – deepest site). Temporally, both samplers showed the highest mean abundances at thermal stratification period. In general, the extent of spatial data collected throughout the vertical gradient provided better estimations in the limnetic area for the attributes analyzed: zooplankton density, richness, specific diversity, equitability and cumulative richness. Zooplankton sampling by vertical hauls through the euphotic zone was more efficient, but in order to obtain integrated data and according to the collector’s curve it might be useful to adopt both methodologies.

title: A Influência da Taxa de Câmbio e Renda Mundial Sobre as Exportações Brasileiras de Soja (2000-2015)

description: Abstract: This paper proposes to test the possible existence of a long-term relationship between the exchange rate and world income variables on the performance of Brazilian soybean exports. For this purpose, an econometric model capable of describing the level of sensitivity (elasticity) of the explanatory variables between January 2000 and December 2015 is estimated. The empirical strategy adopted was the use of time series methods, unit root test, Johansen cointegration test, autoregressive vector model (VAR), called error correction vector model (VECM), impulse-response function and the decomposition of variance prediction errors. The results showed that only the global income variable was relevant to explain the oscillations that occurred over time in the dependent soybean export variable, revealing the importance of the international scenario for the Brazilian sales of the commodity. The variable exchange rate showed a sign contrary to economic theory; however, it registered a significant coefficient. In the short-term analysis, it was observed that there is a certain time lag for short-term imbalances to be corrected in the long run.

title: Lizard assemblages on sandy coastal plains in southeastern Brazil: An analysis of occurrence and composition, and the role of habitat structure

description: Abstract Data on the structure of lizard communities in the different biomes and ecosystems of Brazil are still limited. In this study, we related the species richness, abundance and the spatial occurrence of lizards to the structure of the vegetation found on the coast of the state of Espírito Santo, southeastern Brazil, to determine whether habitat influences the structure of lizard communities. We conducted fieldwork in 2012, 2013 and 2014, collecting data in standardized samples. We analyze whether variables of vegetation structure influenced species richness and abundance, using Generalized Linear Models (GLMs). We recorded 12 lizard species from eight families. In general, species richness and abundance were similar among sites. Locally, we recorded the highest species richness in shrubby vegetation, open Clusia vegetation, and the restinga forest zone. Bromeliads explained the occurrence of teiids, although there was no systematic relationship between species richness and vegetation structure. Our results provide important insights into the characteristics of the lizard communities found on sandy coastal plains and contribute to the conservation of these species in these ecosystems.

title: Ecotoxicology assay for the evaluation of environmental water quality in a tropical urban estuary

description: Abstract Most studies evaluating the impacts of river pollution in the semi-arid region of Brazil have been geared towards physiochemical analyses, and investigations of the adverse effects of water pollution on associated organisms are scarce. This study aimed to evaluate the water quality in the Poxim river estuary in Aracaju, Sergipe throughout the dry and rainy season by evaluating the survival of the microcrustacean Mysidopsis juniae and physicochemical analyses. The evaluation of physiochemical parameters revealed a decrease in dissolved oxygen content in the rainy season. However, there was a significant reduction in microcrustacean survival in samples during the dry season, when the river flow is reduced and effluents become concentrated. These results suggest that pollutants received and carried by the waters of the Poxim River contribute to the reduction of environmental quality in the estuary, and this impact may vary according to dry and rainy patterns, that are uncertain considering the impacts of climate change on tropical regions.

title: MicroRNAs: new biomarkers and promising therapeutic targets for diabetic kidney disease

description: Abstract Diabetic kidney disease (DKD) is a chronic complication of diabetes mellitus associated with significant morbidity and mortality regarded as a global health issue. MicroRNAs - small RNA molecules responsible for the post-transcriptional regulation of gene expression by degradation of messenger RNA or translational repression of protein synthesis - rank among the factors linked to the development and progression of DKD. This study aimed to offer a narrative review on investigations around the use of microRNAs in the diagnosis, monitoring, and treatment of DKD. Various microRNAs are involved in the pathogenesis of DKD, while others have a role in nephroprotection and thus serve as promising therapeutic targets for DKD. Serum and urine microRNAs levels have also been considered in the early diagnosis and monitoring of individuals with DKD, since increases in albuminuria, decreases in the glomerular filtration rate, and progression of DKD have been linked to changes in the levels of some microRNAs.

title: A study of variations of the soil temperature via heat equation

description: Abstract In this article, firstly will be presented a review of the problem that relates the temperature of the soil surface to its temperature at a given depth, i. e. , through periodic variation of temperature at the soil surface, will be wanted to verify the influence caused by this a certain depth, ignoring influences of the radioactive processes of the interior of the Earth, that represent ideal conditions. In the modeling of the problem in question, the known Heat Equation is used, making an analogy to the problem of conducting heat in a semi-infinite bar, thermally isolated on its sides. Mathematical details of the solution of the heat equation will be presented. The soil temperature variation in relation to the surface on a summer day and on a winter day in the city of São Paulo will be used as a case study with the data provided by the meteorological station of the Institute of Astronomy, Geophysics and Atmospheric Sciences (IAG) of USP.
