title: PRODUCTION ECOPHYSIOLOGY OF THE GRAFTED AND NON-GRAFTED TOMATO PLANTS GROWN IN SUBSTRATE

description: ABSTRACT Grafting can be an ally in the vegetable’s soilless cultivation, being the objective of this work evaluate the growth and production, as well as to define the thermal sum and trophic limit of grafted and non-grafted tomato plants cultivated in substrate. The experiments were conducted in a protected environment in the city of Jaguari-RS, in two growing seasons in the years 2019 and 2020. Italian and Gaucho tomato cultivars were used, the rootstock was chosen for giving vigor and longevity to the plants. Yield data were obtained through weekly fruit harvesting, growth data through periodic collections of whole plants and the total biomass obtained at the end of the experiments. Grafted plants show greater vegetative growth regardless of the crop season; however, non-grafted plants are more productive in a growing cycle with restricted light and low temperatures. Grafted plants require a greater thermal sum to complete their phenological stages. The trophic limit for grafted and non-grafted plants of Italian and Gaucho tomato cultivars is 4.8 MJ/m2/day.

title: CONCEPTIONS AND LEADERSHIP PRINCIPLES OF HIGH-PERFORMANCE BRAZILIAN SOCCER COACHES

description: ABSTRACT The aim of this study was to analyze the conceptions and leadership principles of high-performance coaches in Brazilian soccer. Participants were five male soccer coaches who have worked in the Brazilian first division, winning state and national titles, and having experience in international teams. Semi-structured interviews were performed. Main evidences show several competencies, management strategies, professional knowledge, principles, and personal values. We concluded that the coaches have tacit instinctive procedural knowledge that results in a disconnected leadership philosophy and interpersonal knowledge more evident. It is suggested that coaches use the three-phase leadership model and the practice of systematic reflection in order to enhance their leadership effectiveness.

title: INVESTIGATION OF THE ELECTROCHEMICAL ACTIVITY OF AN Al-Cu-Li ALLOY AFTER FRICTION STIR WELDING PROCESS

description: In this work, the local electrochemical activity of the zones coupled by Friction Stir Welding (FSW) of an Al-Cu-Li alloy was studied and the results were correlated to the microstructural characteristics of each zone. Electrochemical studies were carried out in the zones affected by welding using cyclic voltammetry (CV) and scanning electrochemical techniques (namely, SECM - Scanning Electrochemical Microscopy and LEIS - Local electrochemical impedance spectroscopy). The results showed that the welding joint (WJ) is predominantly cathodic relatively to the heat affected zones (HAZ). The HAZ was always anodic and showed the highest electrochemical activities among the tested ones. The high electrochemical activity of the HAZ was associated with the effect of galvanic coupling between the cathodic region (WJ) and the anodic region (HAZ). In addition, the advancing side (AS) presented increased electrochemical activity compared to the retreating one (RS).

title: Validation of an analytical method for the determination of fatty acids in sheep blood serum samples

description: Low-density dispersive liquid-liquid microextraction with a subsequent esterification step was proposed in this study for the determination of linoleic acid and stearic acid in sheep blood serum samples. The method developed aimed to quickly and efficiently extract and esterify both fatty acids with subsequent analysis by gas chromatography/flame ionization detection. The extraction method was optimized with Scheffé’s polynomial model for three-component mixtures. The method was validated according to the parameters established by Eurachem Guide (2014). The optimal extraction conditions for LD-DLLME were 1400 µL of dispersion medium (MgCl2 0.017%), 400 µL of extractor solvent (toluene) and 1200 µL of dispersion solvent (methanol). The method performance showed adequate selectivity, sensitivity and precision to be applied to real samples, with an average recovery of 98.54% for linoleic acid and 103.83% for stearic acid. LD-DLLME was superior to the traditional method of analysis, which has been used until now for the determination of fatty acids in blood serum samples from ruminants. The analysis of real samples showed that the developed method is efficient for monitoring these substances in ruminants.

title: Oral health policies and decision-making process in Brazil, Colombia and Chile

description: Abstract Public health policies are crucial for the well-being of the general population; however, the health systems of developed countries still do not include oral health in its system. Thus, it is necessary to understand the process of decision-making in oral health policies to create opportunities for countries to achieve an overall positive health outcome, including oral health. This study aimed to identify the factors influencing the inclusion of oral health on the political agenda in Brazil, Colombia, and Chile. The study sample involved decision-makers at political, technical, and academic levels. The extracted data were analyzed using the software Maxqda® and Kingdon´s theoretical model; defining interactive variables that produce a “window of opportunity” to define the agenda and the insertion of theme in formulating public policies. The decision-making process regarding oral health is influenced by many factors like the need to improve the overall oral health of the population, identified through national epidemiological studies, and the importance of individuals in positions involving political decision-making, who advocate for oral health. Strategies were developed in partnership with the academy that focused on the health rights of the population provided by law; territorial and national programs were also developed. The inclusion and creation of oral health policies depend on actors who advocate for thematic and scientific evidence to support decision-making. A close relationship between academia and stakeholders and knowledge translation is important for the development of public policies that can be effective for health systems.

title: AGREEMENT AND VALIDITY BETWEEN BODY FAT ESTIMATED BY SKINFOLD MEASUREMENT AND AIR DISPLACEMENT PLETHYSMOGRAPHY IN ADOLESCENTS

description: ABSTRACT Objective: Assess the agreement and validity between relative body fat percentages estimated using anthropometric measurements and air displacement plethysmography (ADP). Methods: A cross-sectional study was conducted on 118 adolescents (60 females) aged 10 to 14 years (x̄=12.19, sd=1.18). Adolescents were classified as eutrophic or with overweight according to body mass index (body weight/height2) (x̄=20,12, sd=3,56). Measurements of skinfold thickness (triceps and medial calf) were collected and used to estimate relative body fat by the Slaughter equation. ADP was used as a reference method for the estimation of relative body fat. Agreement between body fat measurement methods (anthropometry × ADP) was analyzed by the Bland-Altman method. The mean error (ME) was calculated by subtracting the body fat percentage estimated by the Slaughter equation from the body fat percentage estimated by ADP. Validity was tested with the concordance correlation coefficient (CCC). Results: There was no agreement between the methods, regardless of sex and weight status. For boys with overweight (ME = 4.52; p = 0.007), eutrophic girls (ME = 6.37; p &lt; 0.001), and girls with overweight (ME = 5.55; p &lt; 0.001), the Slaughter equation resulted in overestimation of body fat compared with ADP. Skinfold equations did not demonstrate validity when compared with ADP. Conclusion: Slaughter's skinfold equations did not demonstrate agreement and validity compared with ADP in either sex or weight status. Skinfold equations should be used with caution and, whenever possible, in combination with other body composition indicators.

title: EFFECT OF STANDARDIZING OBSERVATION AND RATING CRITERIA FOR THE FRONT CRAWL STROKE TECHNIQUE ON INTER- AND INTRA-RATER RELIABILITY

description: ABSTRACT This study aimed to assess the effect of standardizing observation and rating criteria for the front crawl stroke technique on inter- and intra-rater reliability in order to propose an observation list. Two teachers and two competitive swimming coaches with different academic backgrounds were responsible for evaluating the front crawl stroke technique of 44 swimmers using video. Each swimmer completed a 25m course at a comfortable speed, having their displacement recorded in the lateral and frontal planes, both submerged and out of water, in the final 10 m of the pool. Throughout the recording, the swimmers did not breath laterally. Only the movement performed by the right arm was the raters’ focus of observation and was based on a checklist. After the shooting, the raters participated in three stages: in the first stage, there was an intervention to standardize the observation and rating criteria; inter-rater agreement was tested in the second stage, while intra-rater agreement was obtained in the third. In the second stage of the study, the agreement ranged from small to low (k=0.08 and k=0.38). In the third stage, some raters showed poor and low agreement (k=-0.13 and k=0.35), while others showed agreement between reasonable and virtually perfect (k=0.64 and k=0.87). From the results presented, it was concluded that the intervention proposal did not have the desired effect of standardizing the observation and rating criteria among the raters.

title: External financial support and economic stabilization

description: ABSTRACT This essay tries to evaluate Minister Marcílio Marques Moreira’s approach on Brazil’s external debt negotiations. It starts recognizing that external debt restructuring should contribute simultaneously to the correction of public sector financial imbalances and to the stability of the exchange rate. The decision to simply adhere to current Paris Club and Brady Plan type agreements for middle-income countries will result in small debt service relief. Minister Marcílio’s strategy requires therefore further public sector adjustment and new capital inflows to succeed. The correction of public sector imbalances has not been achieved yet, and foreign investors, in the face of high macroeconomic instability, still cling to short term instruments with high returns which are known to be unsuitable to finance stabilization policies. The signment of agreements with external creditor before achieving the requirements to meet them in a non-inflationary way is the main flaw of the strategy.
