title: Response of four woody species to salinity and water deficit in initial growth phase

description: ABSTRACT The objective of this study was to evaluate the growth of forest species under conditions of salinity and water deficit. The experimental design was completely randomized in a triple factorial scheme with four forest species (Neem - Azadirachta indica A. Juss, ‘Aroeira’ - Myracrodruon urundeuva Fr Allemão, ‘Ipê’ - Tabebuia impetiginosa (Mart. ex. DC.) Standl and ‘Sabiá’ - Mimosa caesalpiniifoliaBenth), two salinity levels (1.2 and 8.6 dS m-1) and two water regimes (with and without water restriction). Plant height, stem diameter, number of leaves, shoot dry matter, root dry matter and total dry matter were measured. For all the studied variables, there was statistical significance for the factors species (A) and salinity (B), individually. However, water deficit (Factor C) and the interaction among factors (A x B x C) did not cause any statistical effect. The 50% reduction in water replacement for the four species studied was not enough to cause significant damage to plant growth, with a mean reduction in dry matter production lower than 10%. It was observed that the tolerance index found varied according to the imposition of the stresses, being caused mainly by salinity. Based on shoot dry matter production, the species Neem behaved as moderately tolerant, while the other species were moderately sensitive to salinity. The applied water deficit was not enough to intensify the effects of the salt stress under the conditions of the present study.

title: Nitrous oxide emission in response to N application in irrigated sugarcane

description: ABSTRACT The objective of this study was to compare the emissions of nitrous oxide (N2O) resulting from the application of nitrogen (N) and potassium (K) doses in fertigated sugarcane, in comparison to emissions from conventional fertilizer application. The study was conducted in the experimental area of Embrapa Mid-North, Teresina, Piauí state, Brazil, from August 2014 to January 2015. The experimental design was in randomized blocks, analyzed in a (2 x 2) +1 factorial scheme, with four replicates. The treatments consisted of the combination of two doses of N and K2O (60-120 and 120-180 kg ha-1, respectively) and two methods of application (in soil and fertigation), and a control. The use of fertigation reduced the emissions of N2O in sugarcane compared with the crop under conventional fertilization. Increase in N dose from 60 to 120 kg ha-1 applied through fertigation did not affect N2O emissions, while 60 and 120 kg ha-1 applied in the soil led to 40.6 and 50.2% increases in N2O emissions, respectively. The application of 60 and 120 kg ha-1 of N in the soil led to higher N2O emission factor, being 1.39 and 2.08% higher than in the crop fertigated with 60 and 120 kg ha-1 of N, respectively.

title: Influence of clay surfactants polarity on the crystallization and rheological behavior of nanocomposites of PDLLA

description: The effect of clay hydrophobicity on the cold crystallization and rheological properties of nanocomposites of poly(D,L-lactic acid) (PDLLA) was investigated. Crystallization was evaluated by DSC for isothermal and non-isothermal conditions. The clay modified with a hydrophilic surfactant acts as a nucleating agent, while the clay modified with a hydrophobic surfactant acts in an opposite way. The Avrami and Ozawa parameters showed a three-dimensional spherulitic growth for all samples and the activation energy increased for the hydrophobic clay and decrease for the hydrophilic one. The equilibrium melting point for the PDLLA was found at 161ºC, being slightly altered as function of the surfactant polarity. The rheological behavior was investigated in terms of Isothermal Flow-Induced Crystallization and Structural Recovery. The hydrophobic clay showed to reduce the mobility of chains and retard the chain relaxation, which is attributed to the formation of a network, while the hydrophilic clay increased the chain mobility.

title: Existing capacity for renal replacement therapy and site-specific practices for managing acute kidney injury at centers participating in the BaSICS trial

description: ABSTRACT Objective: To investigate the existing capacity for renal replacement therapy and site-specific practices for managing acute kidney injury at centers participating in the BaSICS trial. Methods: A questionnaire was provided to the chairs of 61 intensive care units enrolled in a randomized clinical trial in Brazil. A total of 124 physicians completed the questionnaire. Results: Approximately 15% of the patients admitted to the analyzed intensive care units received renal replacement therapy at the time of data collection. At least one renal replacement method was available in all of the analyzed units. Continuous methods were available more frequently at the private units than at the public units. The time from indication to onset of treatment was longer at the public units than at private units. The main obstacles to treatment initiation at public intensive care units were related to the availability of equipment and personnel, while the main bottleneck at private units was the nephrologist assessment. A considerable proportion of the participants stated that they would change their approach to renal replacement therapy if there were no limitations on the availability of methods in their units. Conclusion: There was wide variation in the availability of resources for renal replacement therapy and in the management of acute kidney injury in Brazilian intensive care units. This information should be taken into account when planning clinical trials focused on this topic in Brazil.

title: CuO Rapid Synthesis with Different Morphologies by the Microwave Hydrothermal Method

description: CuO structures were synthesized by microwave hydrothermal treatment using two different mineralizing agents (NaOH and NH4OH) and were evaluated as photocatalysts. The materials were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and Brunauer-Emmett-Teller (BET) surface area analysis. The XRD patterns indicated the formation of the monoclinic phase in both samples with 13.78 and 14.23 nm crystallite size. SEM analysis showed different agglomerates morphologies based on the mineralization agent employed. The CuO nanostructure synthesized with NH4OH presented agglomerated like-plates which results in a spherical shape, whereas the material synthesized with NaOH presented an agglomerate of larger plates. Both samples showed photocatalytic activity against RNL azo dye. The quasi-spherical shape CuO material reached 93 % of the discoloration.

title: Estimating the optimal market price to sell an apartment

description: Abstract This paper demonstrates an investment economic analysis model based on Real Option Valuation Theory applied to decision-making of individual real estate investors. The model captures the valuation of flexibilities caused by expected market trend and uncertainty and offers an optimized value for the investment opportunity. A Real Option for investment delay is used applied to the case of postponing the selling of an apartment until the estimated "best" optimal market price and option value. Application of the model is made using market data from three Brazilian major cities' real estate market. As an important finding we have the estimation of an expanded Net Present Value for the investment when apartment selling is exercised at the optimal market price defined. It is possible to use this model to forecast what would be the optimal price and moment to sell an apartment in an investor point of view.

title: Characterization of patients transported with extracorporeal respiratory and/or cardiovascular support in the State of São Paulo, Brazil

description: ABSTRACT Objective: To characterize the transport of severely ill patients with extracorporeal respiratory or cardiovascular support. Methods: A series of 18 patients in the state of São Paulo, Brazil is described. All patients were consecutively evaluated by a multidisciplinary team at the hospital of origin. The patients were rescued, and extracorporeal membrane oxygenation support was provided on site. The patients were then transported to referral hospitals for extracorporeal membrane oxygenation support. Data were retrieved from a prospectively collected database. Results: From 2011 to 2017, 18 patients aged 29 (25 - 31) years with a SAPS 3 of 84 (68 - 92) and main primary diagnosis of leptospirosis and influenza A (H1N1) virus were transported to three referral hospitals in São Paulo. A median distance of 39 (15 - 82) km was traveled on each rescue mission during a period of 360 (308 - 431) min. A median of one (0 - 2) nurse, three (2 - 3) physicians, and one (0 - 1) physical therapist was present per rescue. Seventeen rescues were made by ambulance, and one rescue was made by helicopter. The observed complications were interruption in the energy supply to the pump in two cases (11%) and oxygen saturation &lt; 70% in two cases. Thirteen patients (72%) survived and were discharged from the hospital. Among the nonsurvivors, there were two cases of brain death, two cases of multiple organ dysfunction syndrome, and one case of irreversible pulmonary fibrosis. Conclusions: Transportation with extracorporeal support occurred without serious complications, and the hospital survival rate was high.

title: Study of Microstructure and Thermal Properties of the Low Melting Bi-In-Sn Eutectic Alloys

description: Beside their technological importance in soldering, the low melting eutectic alloys based on bismuth and indium have potential for commercial application in the field of phase-change materials (PCMs). In this respect, the knowledge of their microstructure and thermal properties such as melting temperature, latent heat of melting, supercooling tendency, thermal conductivity, etc. is of large importance. In this study, two ternary eutectic Bi-In-Sn alloys were investigated by means of scanning electron microscopy (SEM) with energy dispersive X-ray spectrometry (EDS) and differential scanning calorimetry (DSC). Microstructure of the prepared eutectic alloys was analyzed using SEM-EDS and identification of co-existing phases was done. Melting temperatures and latent heats of eutectic melting were measured using DSC technique. Experimentally obtained results were compared with the results of thermodynamic calculation according to CALPHAD (calculation of phase diagram) approach and good mutual agreement was obtained.

title: Social support of family and friends for the practice of physical activity of adolescents: a systematic review

description: Abstract Background Social support has been reported as an important predictor for the practice and maintenance of behaviors related to physical activity among adolescents. Objective The objective of this study is to analyze scientific evidence that addresses the associations between social support of family, parents and friends for the practice of physical activity of adolescents. Method We selected articles published in Portuguese or English, that were indexed until January 2017, with adolescents aged between 14 and 19 years, transverse and longitudinal originals inserted in PubMed, SCOPUS, Scielo and Lilacs databases. Among the 3268 studies identified in the search, and after the stages of article selection, 27 met the inclusion criteria and were entirety analyzed. Results The studies were published in the last decade and carried out in different countries. Social support was related to physical activity, both in transverse and longitudinal studies. In these studies, it was found that adolescents who received greater general social support, as well as support from parents, friends and relatives, showed higher levels of physical activity practice. Conclusion Social support is an important factor associated with the level of physical activity practice in adolescents. Thus, programs to promote physical activity should be directed not only to adolescents but also to the social network that surrounds them.
