title: Human Heat stress risk prediction in the Brazilian semiarid Region based on the Wet-Bulb Globe Temperature

description: Abstract: Objective: the aim of this study is to map thermal stress risks for human health at the São Francisco River Basin (SFRB) in the Semiarid region, for climatic scenarios RCP 4.5 and 8.5. Methods: The heat stress conditions were defined by the Wet Bulb Globe Temperature (WBGT) indicator and by the average number of annual days in which the WBGT values exceeded the 90th percentile of the reference period. The WBGT was estimated for the climate scenarios RCP 4.5 (intermediate) and 8.5 (pessimistic) for the period 2011-2090 comparing to the period of reference (1961-2005). Results: The projections show that for the pessimistic scenario practically all municipalities of the SFRB region can reach values of WBGT that indicate a high risk for heat stress in the period 2071-2099. For this same scenario and period, the municipalities of the Lower and Under-average regions may present values of WBGT above the 90th percentile of the reference period in more than 90% of the days/year. Conclusions: These results show that, if the emission of greenhouse gases continues in the present proportions, some municipalities of the SFRB region may present a high risk for heat stress affecting the work capacity and the practice of physical exercises.

title: Doxycycline release and antibacterial activity from PMMA/PEO electrospun fiber mats

description: Abstract Objective: To investigate the use of polymethyl methacrylate (PMMA) electrospun fiber mats containing different amounts of polyethylene oxide (PEO) as a doxycycline delivery system and to test antibacterial activity against an oral pathogen. Methodology: PMMA powders or PEO (mol wt 200 Kd) (10,20,30% w/w/) were dissolved in N, N-dimethylformamide (DMF) to obtain a final polymer concentration of 15% in DMF (w/v). 2% Doxycycline monohydrate was added to the solutions and submitted to vortex mixing. The solution was transferred to a plastic syringe and fit into a nanofiber electrospinning unit. The parameters applied were: voltage at 17.2 kV; distance of 20 cm between the needle tip and the collector plate; target speed at 2 m/min; and transverse speed at 1cm/min. Syringe pump speed was 0.15 mm/min. The drug release analysis was performed by removing aliquots of the drug-containing solution (in PBS) at specific periods. Doxycycline release was quantified using RP-HPLC. Fiber mats from all groups had their antibacterial action tested against S. mutans based on inhibition halos formed around the specimens. The experiments were performed in triplicate. Gravimetric analysis at specific periods was performed to determine any polymer loss. Morphological characterization of the electrospun fibers was completed under an optical microscope followed by SEM analysis. Results: The addition of PEO to the PMMA fibers did not affect the appearance and diameter of fibers. However, increasing the %PEO caused higher doxycycline release in the first 24 h. Fibers containing 30% PEO showed statistically significant higher release when compared with the other groups. Doxycycline released from the fibers containing 20% or 30% of PEO showed effective against S. mutans. Conclusion: The incorporation of PEO at 20% and 30% into PMMA fiber mat resulted in effective drug release systems, with detected antibacterial activity against S. mutans.

title: Estimation of genetic merit of diallel hybrids of sweet pepper by mixed models

description: ABSTRACT: The use of mixed models for evaluating diallel crosses is a highly timely option to the reliable prediction of progeny genetic values. In the sweet pepper crop, hybrids are commercially explored on a large scale, mainly because of their characteristics of economic importance. This study aimed to assess the potential of hybrids obtained from a partial diallel among five sweet pepper lines developed for the hydroponic cultivation system and two simple hybrids, by applying mixed models. It was performed crosses in the partial diallel scheme among the (L1B, L6, L7, L18, and L19) lines and the simple hybrids ‘Valdor’ and ‘Atlantis’. Plants were cultivated in hydroponic system with substrate and irrigated three times a day using nutrient solution. On the basis of mixed models, the following traits were assessed: mean fruit diameter (FD), mean fruit length (FL), mean fruit number per plant (FNP), mean fruit mass (FM), early yield (EYIELD), and mean fruit mass per plant (FMP). The L6 line was the one that showed the highest estimate of general combination capacity for FMP, FM, and EYIELD, proving to be promising for recommendation. The hybrid that provided the best specific combining ability for FD, FM, FMP, and EYIELD was L6 x ‘Valdor’. Triple hybrids were efficient to maximize yield for the traits of interest by the use of the mixed model.

title: Analysis of the relations of the logistic variables with the organisation and strategy of construction companies

description: Abstract Building efficiently with short deadlines and lower costs is an objective that builders strive to achieve in order to survive in an increasingly competitive market. Due to the importance of logistics in any organisation, this article aims to understand how the mechanisms by which variables related to logistics affect the functioning of an organisation and influence the strategy of construction companies. For this purpose, an applied, descriptive study of qualitative and transverse time was developed. The main procedure chosen for the study was the Survey method with a correlation analysis between variables based on Micmac. The results showed that organisations have a predisposition to establish partnership contracts, seeking information from suppliers and frequent joint actions to reduce execution deadlines. They also seek to have a closer relationship with clients.The results of the research project also indicate that logistics has little influence on the dynamics of the system and that the strategic variables stand out as an important role in the process of development of the company.

title: Metrics of benthic communities and habitat quality associated to different types of land use

description: ABSTRACT Aquatic ecosystems are under severe anthropogenic modifications. Thus, the dependent biological communities in these environments are also changed. The objective of this study was to investigate the effects of urban development in a highly impacted ecosystem. We selected 15 sampling points along the stream Ribeirão Vermelho, in which were sampled benthic macroinvertebrates and assessed the water and habitat diversity. It was found an impact gradient, with some the reference points classified as natural and others as impacted. There was a significant difference in all biological indicators used. The total number of taxa, the wealth of Diptera, the taxa Ephemeroptera, Plecoptera and Trichoptera, and the diversity indices, the Water Quality Indices, and the percentage of herbivores crushers and predators were significantly higher in points classified as natural and changed. The relative abundances of collectors, filter feeding, chironomids and parasites were significantly lower in sites classified as natural in relation to impacted ones. The metrics of the macroinvertebrate community benthic and Habitat Diversity Protocol were influenced by environmental degradation, being a useful tool for planning and development actions for the preservation of watersheds and the prioritization of high-value transmission systems for protection and rehabilitation of aquatic ecosystems

title: ASSESSING PSYCHOSOCIAL DISTRESS IN BONE METASTASES TREATED WITH ENDOPROSTHESIS

description: ABSTRACT Objective: To compare preoperative and early postoperative levels of psychosocial distress in patients undergoing bone metastasis treatment with endoprosthesis, evaluating its impact on quality of life. Methods: Thirteen patients undergoing endoprosthetic treatment of bone metastasis were assessed at two time points: preoperatively and 30 days postoperatively. The tool used was the Distress Thermometer, a questionnaire for psychosocial screening developed by the National Comprehensive Cancer Network. Distress is considered moderate or severe if the patient scores 4 or higher. Results: The most frequent problems in the preoperative period were “bathing and dressing”. At 30 days, “fatigue” and “nervousness” prevailed. There was a significant improvement in distress when preoperative and 30-day assessments were compared. Conclusion: The surgical treatment of bone metastasis with endoprosthesis results in an early improvement of psychosocial distress as measured by the Distress Thermometer.

title: Embedment strength of wood perpendicular to the grain: comparison of test methods

description: Abstract Connections are the points with higher stress concentrations in wood structures. For the design of this fasteners two parameter are used: tensile strength of the steel and the embedment strength of the wood member. The aim of this study was to compare the testing methods and design criteria of different normative documents (NBR 7190, EN 383, ASTM D-5764, EUROCODE 5 and NDS) to determine the wood embedment strength perpendicular to the grain. Six species of wood (Schizolobium amazonicum, Pinus elliottii var. elliottii, Pinus oocarpa Shiede, Hymenaea sp, Lyptus (Eucalyptus grandis/Eucalyptus urophylla) and Goupia glabra and four metal dower diameters (8 mm, 10 mm, 12 mm and 16 mm) were used in the tests. In all cases, the average value of the experimental results of embedment strength to the grain obtained from the EN 383 standard were the highest; the limit slip of 5 mm between metal dowel and wood member never was reached in tests performed according to this standard. The experimental results obtained in this case presented good agreement with the values calculated according to the design criteria of NBR 7190. It was not possible to carry out the tests according to the NBR 7190 method because of the difficulty to obtain the dimensions required for the specimen in perpendicular direction.

title: Differential Molecular Signature of Human Saliva Using ATR-FTIR Spectroscopy for Chronic Kidney Disease Diagnosis

description: Abstract The symptoms of chronic kidney disease (CKD) are often not specific or absent in the early stages of this illness. Therefore, there is a demand for developing low cost, non-invasive and highly accurate platforms for CKD diagnostics. We hypothesized that the level of specifics salivary components changes when CKD is emplace, which could be clinically used to discriminate CKD patients from healthy subjects. The present study aimed to compare salivary components between CKD patients and matched control subjects by using attenuated total reflection-Fourier Transform Infrared (ATR-FTIR) spectroscopy. The predictive power of salivary components was evaluated by receiver operating characteristic (ROC) curves. Several components were identified, and 4 of them showed different expression (p&lt;0.05) between CKD and control subjects. Thiocyanate (SCN-, 2052 cm-1) and phospholipids/carbohydrates (924 cm-1) vibrational modes using original and second-derivative spectra by ATR-FTIR could potentially be used as salivary biomarkers to differentiate CKD than control subjects. The combination of original and second-derivative spectra by ATR-FTIR of 924 cm-1 vibrational modes could reach 92.8% sensitivity and 85.7% specificity for CKD detection. Despite, the limitation of our investigation, the acquired data indicates that salivary vibrational modes by ATR-FTIR platform should be further explored as an auxiliary diagnostic tool for CKD.

title: REVIEW OF TOTAL KNEE ARTHROPLASTY AND THE BRAZILIAN UNIFIED HEALTH SYSTEM: A NATIONAL PROBLEM

description: ABSTRACT Objectives: To analyze, through DATASUS data, the historical trend of revision of total knee arthroplasty (TKA) in the period between 2008-2016 and to relate them to demographic, regional and national aspects. Methods: Elaboration of a historical series between the period 2008-2016, using the database of DATASUS, in the area of Health Information (TABNET). In order to calculate the incidence, the total number of TKA revisions and as denominator the total national, regional or state population for the period studied was used as numerator. Results: The national rate of procedures per 100,000 inhabitants varied between 0.41 and 0.48 in the analyzed period (mean of 0.44). The Southeast region, with 69% of the SBCJ accredited services and 61% of the SBCJ members, was responsible for 60% of the absolute number of procedures performed in Brazil. Conclusions: In absolute numbers, the Southeast region has the highest volume of procedures. However, the highest rate is found in the South region. The North, Northeast and Central-West regions presented unsatisfactory results, well below the others. Level of evidence IV, Economic and decision analysis - development of economic model or decision.

title: EFFECTS OF A PSYCHOLOGICAL SKILL TRAINING PROGRAM ON ANXIETY LEVELS IN TOP KARATE ATHLETES

description: ABSTRACT Introduction To achieve an improvement in self-regulation, and consequently competitive performance, it is necessary to evaluate psychological skills training programs. It was hypothesized that the introduction of autogenic training and guided imagery could bring about positive changes in anxiety and self-confidence, as compared to regular training and competitive activities. Objective To investigate the effects of a psychological skills training program on the optimization of anxiety and self-confidence. Methods Twenty-four athletes from the Serbian national karate team were divided into experimental (EXP) and control (CON) groups. During eight weeks, both groups underwent an identical karate training and competing program. The program was adapted for top karate athletes according to their daily routines and the specific demands of the activity. In addition, the EXP group underwent the psychological skills training program, based on autogenic training and guided imagery. The Competitive State Anxiety Inventory-2 was used to measure the multidimensional construct of the state of anxiety, and the Movement Imagery Questionnaire-3 to assess individual ability to imagine movements. Results Repeated measures ANOVA results indicated a difference in anxiety levels between the EXP and CON groups after the intervention. Further analysis indicated a decrease in cognitive anxiety and an increase in self-confidence among participants from the EXP group. Conclusion The applied psychological skills program had a positive effect on anxiety optimization and self-confidence levels in top karate athletes. As emotional self-regulation is also crucial for athletes of other sports, the implementation of this intervention can be recommended, provided that it is adapted to the specific characteristics of each sport.

title: Urban Morphology maximisation of Urban PV power generation capacity in the São Paulo neighbourhood of Belenzinho

description: Abstract This study analyses the parameters of urban morphology that condition the PV power generation capacity in a the São Paulo neighbourhood of Belenzinho. Initially, using 3D Rhinoceros® software with Grasshopper® and Diva® plug-ings was modelled based on the isolated variation of the urban parameters to identify the best and worse scores, considering the solar radiation incidence on the rooftops of individual buildings. Thereafter, the Galapagos genetic algorithm was applied with the purpose of combining the urban parameters, identifying the most adequate values for a better use of solar radiation. The analysis carried out showed that intermediate values for plot area ratio and land coverage equal to 0.70 are more suitable for better power generation performance in the neighbourhood unit, while the maximum values allowed by legislation are more in the buildings unit. Thus, the definition of a municipal energy policy for photovoltaic application on the roof of buildings involves an analysis of concentrated or distributed generation solutions in the urban territory, and its appropriation by the land use regulation.
