title: Action of cryoprotectors glucose, trealose and quitosan in maintaining viability of Escherichia coli, Saccharomyces cerevisiae cells after lyophilization

description: Abstract Lyophilization is considered one of the safest techniques for acquiring stability of culture strains. For this process, cryoprotectants, which are substances that protect cell structures during the period of freezing, thawing and dehydration, may be used. The objective of the present work was to evaluate the performance of glucose, trehalose, and chitosan as cryoprotectants for Escherichia coli e Saccharomyces cerevisiae. For statistical treatment, ANOVA and Tukey’s test were used with the software Bioestat, version 5.3. For Escherichia coli Trealose presented better performance after lyophilization, but none of the treatments proved to be effective in prolonging viability up to 60 days of storage. For Saccharomyces cerevisiae all treatments were satisfactory throughout the 60 days evaluated.

title: Translational research and innovation systems in health: implications on the biopharmaceutical segment

description: ABSTRACT The analysis of the dynamics of innovation in health in the context of the National System of Innovation in Health reveals the potential of the articulation of Science, Technology and Innovation (ST&I) institutions with the Health Economic-Industrial Complex (HEIC), in view of the interactions between universities and research institutes with the productive sector. Translational health research depends heavily on the dynamics and relative situation of the HEIC in Brazil regarding the international context. The study analyzes the interactions between pharmaceutical companies and health research groups in the country, using microdata from the CNPq Research Group Directory database (DGP-CNPq), in a methodological approach appropriate to collaborative network studies. Furthermore, it shows the presence of a network of interactions with the productive sector in the biopharmaceutical area and highlights the potential of several Brazilian ST&I institutions to foster the development of the health innovation system. This interaction may acquire a translational perspective for the use of technological knowledge by the Brazilian society insofar as it is articulated with the development of the HEIC in Brazil as a critical link to meet the demands of the Unified Health System.

title: Green Supply Chain Management: an Analysis of the Supplier-Agro Industry Relationship of a Southern Brazilian Company

description: ABSTRACT This study aimed to analyze the supplier and agro industry relationship regarding the required environmental management practices in the perception of managers. These partners are also called suppliers or subcontractors. This agro industry exports to about a hundred and ten countries. It is one of the largest private employers in the country and has approximately one hundred and fourteen thousand employees. The study was conducted in only one plant. In this unit there are one hundred and fifty registered suppliers. Six suppliers were selected that provided the greatest number of services for the surveyed unit over the last year of work. It is a case study, descriptive and whose approach is qualitative. We found that the main practices carried out in the evaluated companies are in relation to solid waste management. Only two of the companies surveyed have a standardized management and adequate management of the waste generated in their processes. Similarly, only one company has positive practices in relation to water resources. Therefore, this work can be considered a guide for improving the practices adopted by small and medium-sized suppliers of Alpha. The role of alpha is essential for induction of Green Supply Chain Management in the supply chain as a whole.

title: One-Stage Power Turbine Preliminary Design and Analysis

description: ABSTRACT: Design and development of gas turbine components are a complex multidisciplinary process. At the beginning of the power class definition and engine configuration it is necessary to conduct a market study. The results obtained are used in gas turbine thermodynamic cycle calculations and analysis in order to define the gas turbine design point. Several possible design points are evaluated during this procedure. After this step, the gas turbine components are designed, including: compressor, combustion chamber and turbine. For industrial gas turbine purposes, it is common to use a free turbine after the gas generator, also commonly named power turbine. In this work, a power turbine was initially designed by meanline techniques, considering internal loss mechanisms, to obtain the main dimensions. The geometries of the components were generated in a 3-D environment to make possible the mesh generation, process to discretize the physical domain into a computational domain and use a 3-D Computational Fluid Dynamics tool. The results from the meanline approach and from the 3-D turbulent flow numerical simulations were compared to verify the turbine operational conditions and its predictions at design and off-design conditions. The gas turbine under study is a project, derived from a low thrust turbojet previously developed by Instituto de Aeronáutica e Espaço. The power turbine project uses the same turbojet gas generator, already designed and currently under tests.

title: Numerical methodology for analyses of tubular KK multiplanar steel joints

description: Abstract Herein is presented a numerical methodology for a static resistance analysis of symmetrically loaded multiplanar KK joints in circular hollow steel sections. This methodology addresses factors related to the simulation of KK joints such as the material properties, the boundary conditions, mesh generation and refinement, incremental load steps and failure criteria. An objective criterion is proposed to identify the two failure modes most often occurring in KK joints. Failure mode 1 is observed when two neighboring diagonal braces loaded in the same sense act as one brace penetrating the chord together. In the failure mode 2, excessive deformation is observed in the chord region between two neighboring braces, folding the chord wall. However, in some cases the failure mode is not easily identified or both failure types are present. The proposed criterion objectively identifies the failure mode. In order to compute the joint resistance, an important failure criterion often adopted in literature for uniplanar K joints is the one known as Lu's deformation. In this paper, a strategy is proposed, which is an extension of Lu's criterion for multiplanar KK joints.

title: Soil Microbial Biomass as an Edge Effect Indicator in Semi-Deciduous Seasonal Forest Fragments

description: ABSTRACT This work had the objective to evaluate the activity and microbial biomass of the soil as an indicator of edge effect in Semi-Deciduous Seasonal Forest fragments. Three fragments of different sizes (small, medium and large) located in the Southwest region of Bahia state were evaluated, in which three sampling ranges were defined in each, and soil samples were collected. The carbon and nitrogen contents of the microbial biomass were determined by the fumigation-extraction method and soil respiration. The microbial biomass carbon (MBC), metabolic carbon quotient (qCO2) and the microbial C:N and MBC:C ratios were discriminating indicators of the edge effect on the soil quality of the studied forest fragments. The integrated analysis of soil microbiological attributes is adequate to evaluate the edge effect in forest fragments. The size of the fragments and their isolation influence the MBC contents, showing greater vulnerability of the smaller fragments in relation to the actions of the external environment.

title: Coal extraction causes sediment toxicity in aquatic environments in Santa Catarina, Brazil

description: Abstract This study evaluated water parameters in ponds affected by coal extraction. Allium cepa assay was used to measure genotoxicity/mutagenicity of the sediment. Samples were collected from four ponds in the southern state of Santa Catarina. Water temperature, pH, dissolved oxygen, conductivity and turbidity were measured. Sediments were analyzed for heavy metals. Elutriate samples were prepared at a ratio of 1:4 sediment:water. Allium cepa bulbs were placed in samples prepared from each pond, with ultrapure water used as negative control and methyl methane sulfonate as positive control. Root length, mitotic index, chromosomal aberrations, micronuclei, and nuclear abnormalities were measured. The pH of two ponds, as well as electrical conductivity and dissolved oxygen of all ponds were below the minimum limits set by Brazilian regulation. All heavy metals analyzed were found in all sediment samples, but only Cd concentration was above the legal limit set by Brazilian law. Allium cepa root growth for samples from Ponds 1, 2, and 4 was significantly lower than the negative control. Meristematic cells exposed to elutriate samples showed no significant changes in cell division. There was a significant increase in total chromosomal aberrations in all treated samples in comparison with the negative control. This study demonstrates that even low concentrations of heavy metals can damage exposed biota, possibly due to synergistic effects. We also found the A. cepa bioassay to be a simple and useful tool for genotoxicity/mutagenicity analyses, and recommend its use for environmental monitoring and management in areas influenced by mining activities.

title: Establishment of Leguminous Trees in the Soil of a Shooting Range

description: ABSTRACT Shooting range activities risk contaminating the soil, posing potential risks to human health, the local biota, and water sources. Considering that soil organisms are the first to be affected by contamination, this study aimed to evaluate the initial growth of the leguminous tree Albizia polycephala and its association with microbes in soil taken from this area. The collected soil was placed in 60-ml tubes with legume seeds and stored in a greenhouse for 60 days. The differences in the legumes’ growth were not related to the physical and chemical properties of the soil, nor to its metal content, but rather to mycorrhizal colonization and nodulation, which were shown to be effective in creating favorable conditions. This indicates that the site under study has great natural potential for the establishment of tree species, which could be impaired if it continues to be used for shooting practice.

title: Deforestation Dynamics in the Nova Bonal Sustainable Development Project, Acre, Brazil

description: ABSTRACT This study assessed the dynamics of the land use and cover changes, deforestation trends and the current status of the Legal Forest Reserves (LFR) and Permanent Protected areas (PPA) in the Nova Bonal Sustainable Development Project (SDP) between 1997-2014. Deforestation datasets and fieldwork were used in this analysis. Our results indicate that there was no trend in the estimated deforestation rate dataset for the SDP, but there was a decreasing trend in deforestation rates within its 10-km buffer zone, most likely due to the scarcity of native forests in that area. The negative environmental area balance of PPA and LFR were observed within the 10-km buffer zone of the SDP. Finally, we conclude that the alternative land and forest uses enforced within the SDP are more effective for environmental conservation than the commonly adopted land uses, especially pastures adopted by conventional colonization located around it.

title: Economic policy and public health: fiscal balance and population wellbeing

description: ABSTRACT Many studies have observed the effects of economic crises and austerity policies on high income countries. However, few and very recent ones start to cover the effects on low and medium income countries. In this perspective, we revise the recent studies focusing on the immediate effects on public health, specially on the most vulnerable population. We preferred to consider the joint effects of the economic crises and austerity for understanding that the funding deficits of social policies and their implications on coverage and quality of service provision are interlinked. Recent publications indicate the decline of basic public health indicators, suggesting that the reduction of investments can already be felt on policies for health promotion, prevention and care. The currently economic debate falsely presents austerity measures as the single alternative for promoting fiscal responsibility. Brazil needs to change its development route not only to fight the effects of the economic crises but also to recover the way for improvement on socioeconomic inclusion and public health.
