title: Numerical implementation of a micromechanics-based viscoelastic model for geomaterials with isotropically distributed micro-fractures

description: Abstract The constitutive behavior of geomaterials is generally affected by the presence at different scales of discontinuity surfaces with different sizes and orientations. According to their mechanical behavior, such discontinuities can be distinguished as cracks or fractures. Fractures are interfaces that can transfer normal and tangential stresses, whereas cracks are discontinuities without stress transfer. Regarding the formulation of the behavior of materials with isotropic distribution of micro-cracks or fractures, previous works had essentially focused on their instantaneous response induced by structural loading. Few research works have addressed time-dependent (delayed) behavior of such materials. The present contribution describes the formulation and computational implementation of a micromechanics-based modeling for viscoelastic media with an isotropic distribution of micro-fractures. The homogenized viscoelastic properties are assessed by implementing a reasoning based on linear homogenization schemes (Mori-Tanaka) together with the correspondence principle for non-aging viscoelastic materials. It is shown that the homogenized viscoelastic behavior can be described by means of a generalized Maxwell rheological model. The computational implementation is developed within the finite element framework to analyze the delayed behavior of geomaterials with the presence of isotropically distributed micro-fractures under plane strain conditions. Several examples of applications are presented with the aim to illustrate the performance of the finite element modeling. The assessment of the approach accuracy and the corresponding code verification are performed by comparing the numerical predictions with analytical solutions for simple and complex geo-structures.

title: Analysis of the alkalinity reduction of the wood-cement composites in the function of the partial replacement of the Portland cement by pozzolans

description: ABSTRACT The objective of this research was to evaluate the alkalinity reduction of the wood-cement composites produced with Portland cement and residual particles of Pinus spp., as a function of the gradual replacement of the Portland cement by the pozzolans silica fume (SA) metakaolin (MK), fly ash (CV), blast slag furnace (EAF), rice husk ash (CCA) and calcined ceramic residue (RCC). For this, 5 cm diameter cylindrical specimens were produced with composites wiyh 100% Portland cement and residual Pinus spp. particles, adopted as reference and with partial cement replacements by 0%, 5%, 10%, 15% and 20% of SA, 0%, 10%, 20%, 30% e 40% de MK, CV, CCA e RCC e 0%, 30%, 40%, 50% e 60% de EAF. The Pinus spp. residue initially underwent pre-treatment type extraction in cold water for a period of 24 hours to improve compatibility with the cementitious matrix. In the production of the composites a superplasticizer additive of 1st generation was used, based on lignosulphonates, naphthalenes and melanins in contents ranging from 0.20% to 7.8% of the cement and pozzolan and content and hydrated calcium chloride (CaCl2.2H2O) was used with accelerator additive in amounts ranging from 0% to 4.5% calculated in mass in relation to the cement content of the composites. The composites were immersed for a period of 91 days and after that period were grounded and added to the deionized water, and the pH was determined through the equilibrium solution. Significant reductions in the pH of the composites were determined in relation to the pH value of the reference composite (12.67) of the order of 10.02% (20% de SA, with 4.5% of CaCl2.2H2O and 4.4% of SP), 12.55% (40% de MK, with 4.5% of CaCl2.2H2O and 7.8% of SP), 5.13% (40% of CVwith 4.5% of CaCl2.2H2O), 3.87% (60% of EAF with 4.5% of CaCl2.2H2O), 15.15% (40% of CCA, with 4.5% of CaCl2.2H2O and 4.2%of SP) and 8.29% (40% of RCC, with 4.5% of CaCl2.2H2O and 2.6% of SP).

title: THE PUBLIC-PRIVATE RELATIONSHIP AND THE MANAGEMENT OF WORK IN STATE HEALTH FOUNDATIONS

description: Abstract The discussions on the public-private relationship highlight the need to provide public management with more managerial and administrative autonomy, agility and flexibility in strategic sectors of the health care system. The qualitative research that was the origin of the present article had the aim of analyzing the work management at the State-Owned Family Health Foundation of Bahia (Fundação Estatal de Saúde da Família da Bahia, in Portuguese) and at the State Health Foundation of Sergipe (Fundação Estadual de Saúde de Sergipe, in Portuguese), using the technique of data triangulation and hermeneutic-dialectical analysis. Managers, workers and users from both states took part in the study, totaling twenty semi-structured interviews. The contextual factors and the actors were analyzed using a model that emphasized the dimensions of the macro- and microcontexts. The satisfactory performance regarding work management may be attributed to the variety and complexity of the factors faced by the direct administration. The interrelationship of the microcontext with subdimensions of the macrocontext contributed favorably to the implementation of the foundations. As contributions to the managers, we developed a table containing indicators for the monitoring of the attributions of the work management at the state-owned foundations. The results and potentialities of these experiences may help face the challenges to management in health, providing it with more efficacy, speed and solvability in health care and work management in the Brazilian Unified Health System.

title: Bond strength evaluation between textiles reinforced mortar with carbon nanotubes and concrete substrate

description: Abstract The influence of using carbon nanotubes to improve bond strength between textiles reinforced mortar and concrete was investigated. Forty-two specimens were tested using double-shear test to evaluate the effect of various parameters such as CNTs addition, type of textile material, bond length and width, and number of TRM layers on the bond behavior. Two types of textile: carbon and basalt fibers were used. Various bond length and width including 50 mm, 100 mm, and 150 mm were considered. Three different percentages of CNTs; 0.05%, 0.1%, and 0.2% by weight of cement, were used. The effect of CNTs addition on the mechanical strength of cement mortar and pull-off strength of TRM were also investigated. Test results showed that adding small amount of CNTs enhanced the tensile and flexural strength of cement mortar, the pull-off strength of the TRM, and the ultimate bond load between the TRM and concrete substrate. The ultimate bond load was highly dependent on the amount of added CNTs, type of textile material, geometry of the bonded area, and number of TRM layers. The SEM images showed the role of the CNTs to enhance the adhesion at the fiber-matrix interface.

title: Ground motions for FEMA P-695 application in subduction zones

description: Abstract The FEMA P-695 report presents a methodology for the rational quantification of seismic performance factors for use in seismic design. Despite the fact that the methodology is comprehensive and covers a wide range of possible applications, it only provides ground motion sets recorded from shallow crustal earthquakes. Therefore, this paper presents a new set of ground motions aimed at extending the scope of the FEMA P-695 methodology to zones prone to subduction earthquakes. To consider the effect of spectral shapes on collapse capacities, the spectral shape factors SSF were also computed. Four light-frame buildings were analyzed to study the impact of using the new ground motion set. Results showed a decrease in collapse capacities of 12.4%, an increase in peak floor accelerations of 31.7%, and an increase in the dissipated hysteretic energy of 15.7%. Additionally, the number of ground motions and the intensity levels of the set proved to be robust enough to provide the same reliability that can be obtained when employing a much larger ground motion set. The ground motions and the information provided in this paper have been designed to be fully consistent with the FEMA P-695 guidelines. However, their application can be extended to other analyses that evaluate the seismic performance of structural systems in subduction areas. A database that includes the proposed ground motion set is available online.

title: Optical coherence tomography angiography findings in patients with branch retinal vein occlusion treated with Anti-VEGF

description: ABSTRACT Purpose: To investigate retinal microvasculature changes in patients treated with anti-VEGF for macular edema secondary to branch retinal vein occlusion. Methods: We examined 38 eyes of 19 patients for the study. We measured superficial and deep capillary plexus vessel densities (%), foveal avascular zone areas (mm2), and central macular thicknesses. Results: Parafoveal superficial and deep capillary plexus values were significantly lower in eyes with branch retinal vein occlusion than in fellow eyes (p&lt;0.001). We found a significant increase in parafoveal deep capillary plexus values after the anti-VEGF treatment (p=0.032). The mean foveal avascular zone was larger in eyes with branch retinal vein occlusion than in control eyes (p&lt;0.001). The mean central macular thickness was significantly higher in eyes with branch retinal vein occlusion than in controls, and we observed a significant decrease in central macular thickness after anti-VEGF treatment (&lt;0.001). In addition, the cystic structures in the deep capillary plexus regressed. Conclusion: Optical coherence tomography angiography enables qualitative and quantitative evaluations during follow-up of patients treated for branch retinal vein occlusion.

title: CLINICAL PHARMACEUTICAL SERVICES IN BRAZIL’S PRIMARY HEALTH CARE

description: Abstract The pharmacist plays an important role in the care for the users of primary health care by providing emancipatory self-care actions, education in health, promotion of health and of the reasonable use of medications. In this context, the present study, through an integrative review of the literature, had the goal of analyzing the types and benefits of the clinical pharmaceutic services developed in primary health care in Brazil. In the SciELO and PUBMED/MEDLINE databases, we gathered articles on the clinical pharmaceutic services developed in primary health care in Brazil published in Portuguese, English and Spanish between 2007 and 2017. The pharmacotherapeutic follow-up is the most studied service, while dispensation and guidance are the activities most often performed by the primary health care pharmacists. Regarding the benefits, the literature shows the coexistence, the importance and the multidimensionality of the clinical pharmaceutic services in the promotion of health and in the reasonable use of medications by the circumscribed community.

title: Effects of a commercial biocide, kasugamycin and consistency of the culture medium on the in vitro establishment of bamboo1

description: ABSTRACT The contamination by microorganisms and oxidation of explants in the in vitro establishment of bamboo are recurrent problems for its micropropagation. In the present study, effects of the biocide Plant Preservative Mixture (PPM™), the antibiotic kasugamycin and the consistency of the culture medium were evaluated in the in vitro establishment of Bambusa vulgaris,Phyllostachys bambusoides and Dendrocalamus asper. The presence of PPM™ in the culture medium had a significant effect using 2 mL L-1 or 4 mL L-1 concentrations, as well as in the liquid culture medium, increasing the plants established in the autumn. Kasugamycin promoted variable responses for all the three species, depending on the season. There was interaction among the factors, demonstrating that higher rates of viable plants can be obtained by combining different strategies to reduce the oxidation and contamination. For the in vitro establishment of B. vulgaris,P. bambusoides and D. asper, it is recommended to add 2 mL L-1 or 4 mL L-1 of PPM™ to the liquid culture medium.
