Determination of critical power using a straight bench press with a test protocol

The purpose of this study was to investigate the validity of critical force test from maximal lactate steady state (MLSS) during resistance test using straight bench press (SBP). Five healthy male volunteers aged (22.6 ± 2.88 years), weight (76.3 ± 11.49 kg) e height (182.6 ± 7.54 cm), trained in resistance exercise, performed four diferent tests to determine: one maximal effort (1RM), critical force using the critical power model (force vs 1/time limit – 20.25 and 30% of 1RM). The CF was the linear coefficient and the anaerobic impulse capacity (CIA) was the angular. MLSS was determined using loads of 80, 90, 100 and 110% of critical force. Blood lactate samples were abtained at each 300sec between each stage of total 1200sec. Maximal 30s test (M30) was accomplished with load of 25% of body weight in SBP. The results showed that the 1 RM was 79.4 Kgf (± 16.98), CF 10.1N (± 2.25), CIA 1756.82 N.s (± 546.96) and the R² 0.984 (± 0.02). The MLSS occurs at 100% CF load. The lactate concentration at the MLSS was 2.2 mmol/L (± 0.77). Significant correlation was observed between MLSS and CF on SBP (r = 0.88, p = 0.05). In M30 the minimum, mean and peak power were (25.0 ± 4.9, 28.0 ± 4.9, and 30.0 ± 4.6 kgf.rps, respectively). The fatigue index was 18.0% (± 6.8). The M30 was significantly correlated with Ppeak and Pmean (r = 0.98 for both, p = 0.003). The CF means has been validated to predict the resistance training and the CIA, showing to be a representative anaerobic parameter in straight bench press

A cultura na Educação Infantil: breves reflexões sobre um campo de disputa de concepções

ABSTRACT. This article is the result of bibliographic research conducted during the specialization course in Early Childhood Education at the Universidade Federal do Norte do Tocantins, Tocantinópolis Center, whose goal was to reflect on the insertion of the culture of writing in early childhood education. The study was justified by the need for theoretical support on the process of insertion of the culture of writing, especially in the lives of children in the early stages of schooling. The theme in question is necessary and relevant for all those involved in education, especially educators who work with children aged 4, 5, and 6, in early childhood education and in the early years of elementary school, since it enables the understanding of fundamental concepts for the insertion of the child in this culture. The results obtained in the research consider that children's learning, development, and knowledge related to writing in Early Childhood Education must be understood and carried out as a process, in constant evolution. More than ever, it is necessary to overcome the conception of a ready-made, finished, only transmitted knowledge, and to establish the commitment to form people who are competent for life, able to solve problems; that is, to understand, to intervene, to transform, to modify, to respect, to seek and to act in reality, by means of their potentialities and countless languages.ABSTRACT.

Simultaneous Papillary Carcinoma in Thyroglossal Duct Cyst and Thyroid

Thyroglossal duct cyst (TDC) is a cystic expansion of a remnant of the thyroglossal duct tract. Carcinomas in the TDC are extremely rare and are usually an incidental finding after the Sistrunk procedure. In this report, an unusual case of a 36-year-old woman with concurrent papillary thyroid carcinoma arising in the TDC and on the thyroid gland is presented, followed by a discussion of the controversies surrounding the possible origins of a papillary carcinoma in the TDC, as well as the current management options

AS LÓGICAS INSTITUCIONAIS INCORPORADAS AO BALANCED SCORECARD (BSC): UM MODELO PARA ESTUDAR A ADAPTAÇÃO DO BSC

Este artigo examina a adaptação das práticas gerenciais, em nível intraorganizacional, com foco no Balanced Scorecard. O objetivo desse estudo é propor um modelo conceitual para o estudo da adaptação do BSC em nível intraorganizacional com base na literatura da lógica institucional e no modelo proposto por Ansari et al. (2010) – de que os padrões específicos de adaptação de práticas dependerão do ajuste entre a prática em difusão e a organização adotante. Neste artigo, sugere-se que a adaptação de práticas de contabilidade gerencial numa organização pode ser determinada pelo ajuste entre a lógica institucional dominante incorporada na empresa e a lógica institucional embutida na prática em difusão. Com base nesta proposição, foi desenvolvido um modelo conceitual para estudar a adaptação do BSC em nível intraorganizacional. Como resultado, oferece-se este modelo conceitual como uma forma analítica de usar o conceito de lógica institucional para explicar o processo de adaptação do BSC em uma organização

Chemical soil and leaf properties in yellow passion fruit cultivation with organic fertilization

The yellow passion fruit presents a high nutritional demand, and successive cultivations in the same area lead the soil to nutritional exhaustion, creating the need for restitution through fertilizers. In the context of organic managements, alternatives must be sought, which, besides improving soil fertility, can increase the contents of soil organic matter. Therefore, this work aimed to evaluate the effect of organic basal fertilization in passion fruit cultivation on the chemical properties of the soil and nutrient contents of the plant. Two experiments were performed in two rural properties, with soils presenting sandy-loam and clay-loam texture. The experimental design was in randomized blocks (RBD), with 5 treatments and 4 blocks. The treatments consisted of the application of organic compost in different planting hole diameters: 0.4 m; 0.8 m; 1.2 m; 1.6 m, and 2.0 m, and their respective volumes of organic compost: 0.0007 m³; 0.03 m³; 0.06 m³, 0.10 m³; 0.16 m³. The chemical characteristics of the soil and the foliar content of nutrients were evaluated. Soil texture interferes with the effects of organic fertilization. Regardless of the texture, fertilization increases the contents of organic matter and P in the soil. The successive organic cultivation in a sandy-loam soil increases the content of P and provides higher foliar contents of N, P, Ca, Mg, S, B, Cu, Fe, Zn, and Na.The yellow passion fruit presents a high nutritional demand, and successive cultivations in the same area lead the soil to nutritional exhaustion, creating the need for restitution through fertilizers.

Organic cultivation of yellow passion fruit using tall seedlings with long root systems

Studies related to adaptation to the environment and different conditions of water availability contribute to decision-making regarding the management of any crop to be implanted. Accordingly, this work aimed to evaluate the yield and quality of organic yellow passion fruit cultivated in a long root system in dryland conditions. The experimental design was in randomized blocks, with five treatments and four replications with four plants each. The treatments consisted of the alteration of the length of the root system, namely: T1 = 25 cm; T2 = 50 cm; T3 = 75 cm; T4 = 100 cm; and T5 = 125 cm. At 120 days after emergence (DAE), the seedlings were transplanted to the field and the following variables were evaluated: plant height (cm) and base diameter (mm) at 120 DAE; total titratable acidity (TTA), total soluble solids (TSS), Ratio (TSS/TTA); and fruit yield. The cultivation of tall seedlings with a long root system provides the maintenance of production during the dry season. The TTA, TSS, and the ratio do not change when modifying the length of the root system, although they do change with the harvest season. The cultivation of passion fruit in an organic system using plants with a long root system with an estimated length of 114 cm provides a higher fruit yield (7,472 kg ha-1) in 22 months of cultivation.Studies related to adaptation to the environment and different conditions of water availability contribute to decision-making regarding the management of any crop to be implanted.

Divulgação científica, uma vacina para combater fake news em tempos de pandemia de covid-19 no Brasil.

The coronavirus pandemic highlighted the need for scientific dissemination practices as a way to combat the process of disinformation and “fake news”. In this context, we seek to identify how university libraries, librarians, gatekeepers act in the promotion of scientific dissemination as a way of combating fake news and disinformation in the context of the covid-1 pandemic in Brazil. This is a qualitative, exploratory and descriptive research, with documentary research and bibliographic review in the scope of scientific dissemination and communication, disinformation and fake news, public university libraries, information professionals in the global pandemic context. Information on covid-19 was also sought in the form of scientific dissemination, on websites and virtual social networks of public university libraries in Rio de Janeiro, as a form of scientific dissemination to the lay public. The results show that scientific dissemination will serve as a possible vaccine against fake news and disinformation, in which the citizen must go through the process of media and information education, in addition to information competence activity with a view to developing critical, reflective and at the same time learning how to recognize reliable sources of information. It emphasizes the role of librarians, journalists and other information professionals in the process of evaluating and selecting information as a subsidy for its use for mass dissemination.Objetivo: identificar ações de divulgação científica sobre Covid-19 promovidas por bibliotecários, gatekeepers, profissionais da saúde e representantes da sociedade civil.Metodologia: pesquisa qualitativa, exploratória e descritiva, com pesquisa documental erevisão bibliográfica no âmbito da Ciência da Informação.

Propagation of yellow mombin by stem and root cuttings treated with indolebutyric acid

Yellow mombin is a fruit species of growing interest in the agro-industrial sector, mainly in the North and Northeast regions of Brazil, although its commercial exploitation is still limited due to the lack of information regarding its propagation, among other factors. In this perspective, this work aimed to study the effect of the application of indolebutyric acid (IBA) in the vegetative propagation of yellow mombin by stem and root cuttings. The experiments were conducted in a plant nursery, under a completely randomized experimental design consisting of six concentrations of IBA (0, 1000, 2000, 3000, 4000 and 5000 mg.kg-1 in industrial talc), four replications, and ten cuttings per plot. The stem cutting experiment also evaluated the effect of the types of cuttings (tanchan, basal, stratified basal, medial, and apical), with the material being collected from a yellow mombin tree in full vegetative growth. The root cuttings were collected from a matrix plant in the stage of vegetative rest and cut into 15 cm length segments. After 120 days, the following variables were evaluated: percentage of living, sprouted, rooted, and calloused cuttings, and dry mass of roots and sprouts. The cuttings of the tanchan type showed higher survival and sprouting percentages, regardless of the concentration of IBA applied, whereas the rooting rate was low. The application of IBA increased the rooting percentage of the root cuttings until the maximum concentration of 5000 mg.kg-1, reaching 77.5%, although it did not influence the other variables analyzed. The root cuttings of yellow mombin exhibit good regeneration capacity.Yellow mombin is a fruit species of growing interest in the agro-industrial sector, mainly in the North and Northeast regions of Brazil, although its commercial exploitation is still limited due to the lack of information regarding its propagation, among other factors.
