title: Crop systems and topdressing nitrogen on grain yield and technological attributes of common bean under no-tillage

description: ABSTRACT Common bean has been the main crop in succession to corn and Brachiaria in no-tillage systems, in the Brazilian Savannah. This study aimed to evaluate the influence of crop systems and topdressing nitrogen on grain yield and technological attributes of common bean under no-tillage. A randomized block design, in a split-plot arrangement, with four replications, was used. The plots consisted of three crop systems (corn in sole crop, corn + Urochloa ruziziensis intercropped and U. ruziziensis in sole crop) and the subplots by five nitrogen rates (0 kg ha-1, 40 kg ha-1, 80 kg ha-1, 120 kg ha-1 and 160 kg ha-1). There is interaction between predecessor cropping systems and N rates for grain yield, milling efficiency specifically on sieve 13, as well as for the grain hydration ratio. Increasing topdressing N rates applied on common bean in succession to corn in sole crop promote increases in grain yield, resulting in a milling efficiency in the oblong-hole sieve 14 higher than in the other crop systems evaluated. The increase of the topdressing N rates applied on common bean in succession to corn and U. ruziziensis in sole crops or intercropped does not influence the time for maximum hydration of the grains, but reduces their cooking time, mainly in succession to U. ruziziensis and corn in sole crops.

title: The emergence of the additional language teacher/adviser under the complexity paradigm

description: ABSTRACT In this text, we discuss the emergence of a complex additional language teacher/adviser under the complexity theory framework by reflecting upon disturbances in the teaching and learning subsystems of pre-service education. The complex teacher/adviser values all sub- and suprasystems, embraces the fractalized identities, conciliates assorted conceptions associated to this role, energizes and moves different systems linked to the profession, and uses several methods and approaches to language teaching and learning. We bring up some evidences of the complex teacher/adviser emergence in language teaching preparation and in language learning advising.

title: Clinical analysis on risk factors and prognosis of early post-traumatic epilepsy

description: ABSTRACT Objective To analyze the risk factors and prognosis related to early post-traumatic epilepsy (EPTE). Methods One hundred and eighty-six patients with traumatic brain injury were enrolled. Their full clinical data were collected. Single factor analysis and logistic regression analysis of risk factors related to EPTE were performed. The prognosis of patients was determined. Results Single factor analysis showed that there were significant differences of age (p = 0.011), epilepsy history (p &lt; 0.001), injury site (p = 0.004), injury type (p &lt; 0.001) and injury degree (p &lt; 0.001) between the EPTE group (40 patients) and non-EPTE group (146 patients). Logistic regression analysis showed that the injury site, injury type and injury degree were the main risk factors for EPTE. The odds ratio values of injury site, injury type and injury degree were 1.977 (1.473–2.679), 2.096 (1.543–2.842) and 2.376 (1.864–3.609), respectively. The logistic regression equation was P = Exp (-1.473 + 0.698 × injury site + 0.717 × injury type + 0.935 × injury degree). The sensitivity and specificity of injury site, injury type and injury degree for predicting EPTE were 79.2% and 80.5%, 78.9% and 85.7% and 84.2% and 81.0%, respectively. The analysis of prognosis showed that the Glasgow Outcome Scale/Activity of Daily Living Scale scores in the EPTE group were significantly lower than those in non-EPTE group (p &lt; 0.05). Conclusions Injury site, injury type and injury degree are the main risk factors for EPTE. The prognosis of patients with traumatic brain injury can be affected by EPTE.

title: Relationship between sexual hormones, quality of life and postmenopausal sexual function

description: Abstract Objective To assess the relationship between sexual hormones, sexual function and quality of life in postmenopausal women. Method A cross-sectional study was conducted with a convenience sample of 36 postmenopausal women between the ages of 45 and 65 in follow-up at a climacteric outpatient clinic. Mood, quality of life, sexual function and hormonal profile were assessed. Results With regard to sexual hormones and sexual function, a relationship was found between orgasm and luteinizing hormone (r=0.37), orgasm and sex hormone-binding globulin (SHBG) (r=0.39), SHBG and less pain (r=0.44), dehydroepiandrosterone (DHEA) and desire (r=-0.45), as well as between prolactin and lubrication (r=0.33). Sexual hormones and quality of life were related as follows: progesterone and limitations due to physical aspects (r=0.35), SHBG and social aspects (r=0.35), cortisol and pain (r=0.46), DHEA and social aspects (r=-0.40). Finally, the following relationships were found between sexual function and quality of life: sexual desire and vitality, social aspects, state of general health and mental health (r=0.46, r=0.51, r=0.35, and r=0.38, respectively). Arousal, orgasm and satisfaction with sexual life showed a relationship with less physical pain (r=0.40, r=0.42, and r=0.43, respectively). Satisfaction with sexual life was correlated with vitality (r=0.33). Conclusion Different correlations than expected were found in this study regarding the effect of some hormones on sexual function and some aspects of the quality of life of postmenopausal women.

title: The household demand for rice in Brazil: through the Quaids system in 2008/2009

description: Abstract Rice is a staple food in the Brazilian diet, but the slow consumption growth has a direct impact on the sector's expansion. In order to understand the factors affecting this consumption and their interrelationships with other food, this paper estimated the elasticities of demand for ten types of food in Brazilian households using microdata of the Household Budget Survey 2008-2009. Therefore, we applied the Quadratic Almost Ideal Demand System model (Quaids) adjusted for censored consumption and endogeneity of total expenditures. The overall results indicate that the rice has elasticity expenditure less than the unity. The income elasticity of demand reinforces this necessary good behavior, being higher in regions like the Midwest and Southeast. It also indicates that beans are complementary to rice, while bread and cassava flour are important substitutes. Finally, these results may be useful to boost household consumption of this product, through strategies that reduce its price, with the productivity increase or tax changes, or strategies focused on regional markets and to promote the substitution of other foods by rice.

title: THERMODYNAMIC ANALYSIS AND MODELING OF BRAZILIAN CRUDE OIL AND ASPHALTENE SYSTEMS: AN EXPERIMENTAL MEASUREMENT AND A PC-SAFT APPLICATION

description: ABSTRACT Asphaltenes represent the heaviest fraction of crude oils, being recognized by their tendency to self-associate and precipitate. Asphaltene precipitation and subsequent deposition can cause problems in all stages of production. The objective of this paper is to model Brazilian crude oil and asphaltene systems using the PC-SAFT equation of state. Asphaltenes were extracted from crude oil through the addition of different n-alkanes. The PC-SAFT was capable of accurately predicting liquid density for toluene and asphaltenes and boiling point elevation for crude oil at different concentrations of toluene. Asphaltene precipitation from model oil allowed us to evaluate the influence of binary interaction parameters on modeling results. The influence of precipitant agent (n-hexane and n-heptane) on the asphaltene phase behavior was analyzed, showing that n-hexane was able to precipitate more asphaltenes than n-heptane, as expected. Furthermore, simulated results are in agreement with experimental observations: the average relative errors are 3.75 % and 10.25 % for the weight percentage of precipitated asphaltene using n-hexane and n-heptane as precipitant, respectively.

title: A NEW VALIDATED METHOD FOR DETERMINATION OF ROFLUMILAST IN TABLET BY CZE-UV

description: This paper reports a new and validated capillary electrophoresis method to determine Roflumilast (RFL) with an internal standard in tablet. The separation was made on an uncoated fused-silica capillary column 50 cm effective length and 75 µm i.d. 20 mmol L-1 of Na2B4O7 buffer including 15% (v/v) methanol (pH=9.5) was used as background electrolyte. A potential of 20 kV was applied. The developed method was linear in the range of 0.75 µg mL-1 and 15.0 µg mL-1. LOQ and LOD values were 0.074 µg mL-1 and 0.022 µg mL-1 for inter-day, respectively. The precision value was 0.78% for inter-day. The accuracy was between 98.63 and 100.97 as recovery. This study was the first report for the determination of RFL in Daxas® solid dosage form using CE. The validated method was found as rapid, cheap, easy to apply and uses small sample volume, very little organic solvent, and high efficiency and resolution.

title: Relationship between Dyslipidemia, Cultural Factors, and Cardiorespiratory Fitness in Schoolchildren

description: Abstract Background: The presence of dyslipidemia and behavioral aspects are determinants of cardiovascular risk, especially in childhood and adolescence. Objective: To verify possible relationships between dyslipidemia, cultural factors, and cardiorespiratory fitness (CRF) in schoolchildren. Methods: This cross-sectional study evaluated a sample of 1,254 children and adolescents between the ages of 7 and 17 from the South of Brazil, 686 of whom were female. Dyslipidemia was defined as increased levels of at least one of the following lipid profile parameters: triglycerides (TG), total cholesterol (TC) and fractions of high (HDL-c) and low-density lipoprotein (LDL-c). Cultural aspects were evaluated by a self-reported questionnaire. Data were analyzed by logistic regression, considering the odds ratios (OR) and confidence intervals (CI) at 95%. Results: The results revealed a high prevalence of dyslipidemia (41.9%), which was associated with female sex (OR: 1.56; IC: 1.24-1.96) and overweight/obese status (OR: 1.55; IC: 1.20-2.00). When lipid profile parameters were evaluated separately, high levels of LDL-c were observed to be associated with sedentary school transport (OR: 1.59; IC: 1.20-2.09). Schoolchildren who were overweight/obese had higher chances of elevated levels of TC (OR: 1.40; IC: 1.07-1.84) and TG (OR: 3.21; IC: 1.96-5.26). HDL-c was shown to be related to high television time (OR: 1.59; IC: 1.00-2.54). Conclusion: Alterations in lipid parameters are associated with cultural factors, especially those related to sedentary lifestyle and low levels of CRF.

title: Behavioral Influence of Known Prognostic Markers on the Cardiologist's Decision following Acute Coronary Syndrome: the GRACE Score Paradox

description: Abstract Background: Behavioral scientists consistently point out that knowledge does not influence decisions as expected. GRACE Score is a well validated risk model for predicting death of patients with acute coronary syndromes (ACS). However, whether prognostic assessment by this Score modulates medical decision is not known. Objective: To test the hypothesis that the use of a validated risk score rationalizes the choice of invasive strategies for higher risk patients with non-ST-elevation ACS. Methods: ACS patients were consecutively included in this prospective registry. GRACE Score was routinely used by cardiologists as the prognostic risk model. An invasive strategy was defined as an immediate decision of the coronary angiography, which in the selective strategy was only indicated in case of positive non-invasive test or unstable course. Firstly, we evaluated the association between GRACE and invasiviness; secondly, in order to find out the actual determinants of the invasive strategy, we built a propensity model for invasive decision. For this analysis, a p-value &lt; 0.05 was considered as significant. Results: In a sample of 570 patients, an invasive strategy was adopted for 394 (69%). GRACE Score was 118 ± 38 for the invasive group, similar to 116 ± 38 for the selective group (p = 0.64). A propensity score for the invasive strategy was derived from logistic regression: positive troponin and ST-deviation (positive associations) and hemoglobin (negative association). This score predicted an invasive strategy with c-statistics of 0.68 (95%CI: 0.63-0.73), opposed to GRACE Score (AUC 0.51; 95%CI: 0.47-0.57). Conclusion: The dissociation between GRACE Score and invasive decision in ACS suggests that the knowledge of prognostic probabilities might not determine medical decision.
