title: Application of the Restricted Three Bodies Problem in the study of the move the objects of the solar system

description: Abstract After a review in the literature we have seen that the Restricted Three-Body Problem (RTBP) is a topic with some publications focused, primarily, on resolution of the mathematical problem, with very few application in real and contextualized situations. In addition, in analyzing textbooks of classical mechanics we observed that the RTBP is not developed and didactically explored. Based on this facts, our objective in this work is to present, develop and apply the RTBP to simulate the orbits of two objects in the solar system : motion of Earth-trojan asteroid 2010 TK7 and libration of pluto due to Neptune. To solve differential equations of RTBP we uses the cauchy method in a code written in the Python programming language. With this work we hope to demonstrate that the study of the RTBP can be used to contextualize some concepts of celestial mechanics and orbital dynamics.Since it is related to the study of differential equations, with universal gravitation and numerical methods.

title: Quality of life and eating attitudes of health care students

description: ABSTRACT Objective: To assess the quality of life and eating attitudes of health care students of the undergraduate programs of a public university. Method: Observational, cross-sectional, and quantitative study performed in a federal university. Three questionnaires were used for data collection: a socio-demographic and academic, the WHOQOL-BREF and the Eating Attitudes Test (EAT-26). Result: 399 students participated in this study, most women, average age of 22 years, average scores of EAT-26 of 15.12 and quality-of-life averages above 60 points in all domains. The students of the undergraduate program in Nutrition presented more inappropriate eating attitudes than other health care students; as the age evolves, vulnerability to inadequate eating attitudes increases; and the family income influenced negatively the quality of life in Physical and Social domains. Conclusions: Inadequate eating attitude diminishes the quality of life of health care students in all domains of the WHOOQOL-BREF.

title: Enteral fluid therapy administered in continuous flow by naso-ruminal route using three maintenance electrolyte solutions: effects on physiological biomarkers and the hemogram of bovines

description: ABSTRACT: The aim of this study was to evaluate the effects of three enteral electrolyte solutions, each with different energy sources, administrated as continuous flow on the physiological parameters and blood count of healthy Holstein heifers. Six Holstein heifers were used in a crossover design. All animals received all three treatments: solution with calcium propionate, 4g of NaCl, 0.5g of KCl, 0.3g of MgCl2, and 10g of calcium propionate diluted in 1000mL of water (measured osmolarity: 299mOsm/L); solution with glycerol, 4g of NaCl, 0.5g of KCl, 0.3g of MgCl2, 1g of calcium acetate, and 10mL of glycerol in 1000mL of water (measured osmolarity: 287mOsm/L); solution with propylene glycol, 4g of NaCl, 0.5g of KCl, 0.3g of MgCl2, 1g of calcium acetate, and 15mL of propylene glycol in 1000mL of water (measured osmolarity: 378mOsm/L). Physical evaluations and blood samples were collected immediately before the initiation of fluid therapy, at 3-hour intervals over the 12-hour period of fluid therapy, and 12 hours after the end of fluid therapy. Animals presented no signs of stress or discomfort. All solutions resulted in a significant decrease in erythrocyte concentration, hemoglobin concentration, and hematocrit, without affecting the leukogram. Enteral fluid therapy administered as continuous flow via the naso-ruminal route was well-tolerated by animals with minimal effects on animal welfare, even when administered for 12 hours. This technique is indicated as an alternative route for parenteral maintenance fluid therapy. Electrolyte solutions proposed here were able to significantly expand blood volume.

title: Echocardiographic evaluation of dogs subjected to different protocols of anesthetic induction

description: ABSTRACT: The objective of this study was to investigate the echocardiographic changes during anesthesia induction in dogs sedated with acepromazine (0.05mg/kg) and butorphanol (0.3mg/kg) (AB). Twenty-four male dogs, with a mean weight of 12.40kg±3.1kg, were randomly assigned to 4 groups (n=6). Fifteen minutes after administering pre-anesthetic medication, anesthesia with diazepam (0.5mg/kg) and etomidate (1mg/kg) (group DE); diazepam (0.5mg/kg) and ketamine (3mg/kg) (group CD); propofol (4mg/kg) (group P); or ketamine (1mg/kg) and propofol (3mg/kg) (group CP) was administered to the 6 dogs in each group. Systolic blood pressure (SBP) was measured and echocardiography was performed immediately prior to the application of the sedation protocol (baseline), 15 minutes after sedation (M1), and immediately after anesthesia induction (M2). No significant differences were observed in SBP and in hemodynamic variables such as cardiac index, shortening fraction, and ejection fraction, between groups at all time points (M0, M1, and M2) evaluated. The SBP was significantly reduced after anesthetic induction in the dogs of the DE and CP groups. It can be concluded that the protocols DE and CP reduce similarly to SPB in dogs medicated with CD and P to SBP remain stable after anesthetic induction. All anesthetic induction protocols maintained a stable IC in premedicated dogs. None of the protocols evaluated promoted significant echocardiographic changes. Furthermore, the ketamine and diazepam combination had a negative impact on myocardial relaxation.

title: VALIDATION OF COMPUTATIONAL METHODS APPLIED IN MOLECULAR MODELING OF CAFFEINE WITH EPITHELIAL ANTICANCER ACTIVITY: THEORETICAL STUDY OF GEOMETRIC, THERMOCHEMICAL AND SPECTROMETRIC DATA

description: Models validation in QSAR, pharmacophore, docking, and others, can ensure the accuracy and reliability of future predictions in design and selection of molecules with biological activity. In these study, the caffeine molecule was optimized using Hartree-Fock (HF) and Density Functional Theory (DFT/B3LYP) methods, with seven basis sets. Linear correlation data, errors and RMSD values between theoretical and experimental data allowed us to classify the methods and basis sets for evaluating their correspondence with experimental data (geometric parameters, heat capacity, as well as Infrared, Raman and NMR spectra). The HF method has shown the highest correspondence with the experimental data, occupying the top-five rank of the general classification. The HF/6-31G** method was the best one classified and it can be used to model the biological activity of the caffeine molecule.

title: Yield and quality of melon under silicon doses and irrigation management in a greenhouse

description: ABSTRACT The netted melon requires special growing conditions, including a protected environment, an adequate staking system and proper water and nutrient management. This study aimed to assess the effect of irrigation levels and silicon doses on the yield and quality of Sunrise hybrid melons, in a greenhouse. A randomized block design was used, with a 5 x 3 factorial scheme and four replications. The first factor consisted of five silicon doses (0 kg ha-1, 50 kg ha-1, 100 kg ha-1, 150 kg ha-1 and 200 kg ha-1) and the second of three irrigation levels (40 %, 70 % and 100 % of the ETc). The results demonstrated that the applied irrigation levels and silicon doses have no influence on the yield traits of melon plants. The irrigation level corresponding to 100 % of the ETc promotes higher values for soluble solids (9.86 ºBrix) and maturation index (114.9) on fruits. The increase of silicon doses up to 200 kg ha-1 also increases the maturation index in the treatment with the greatest irrigation level and reduces this index at the shallowest level applied.

title: The Resgate Project: History and Archival Science (1982-2014)

description: ABSTRACT The increasingly intense consultation of archive documents demands historians to have knowledge, even if elementary, of archival process and archival science, especially concerning the technical treatment of documental collections, most of all to avoid interpretative misunderstandings. Two of the basics of these areas - the provenance principle and the organicity principle - are considered here in the light of the Projeto Resgate “Barão do Rio Branco” trajectory, especially in the tasks of organizing, re-storing and microfilm and digital reproduction of its results concerning the group of documents under custody of the Arquivo Histórico Ultramarino, in Lisbon. From that point, these annotations also intend to subsidize discussions about future actions of that project.
