Published: May 2018

Contexto: Este estudio presenta la estimación de las emisiones evaporativas generadas en el plantel de distribución de combustibles en el Alto de Ochomogo, Cartago, Costa Rica, y la selección del sistema de recuperación adecuado para reducir la emisión de estos gases a la atmósfera, disminuyendo así los efectos adversos provocados por estos compuestos en el ambiente y la salud de las poblaciones cercanas.Método: Se estimó la tasa de emisiones fugitivas en el proceso de carga de vehículos cisternas, usando factores de emisión de pérdidas de carga, y en el almacenamiento de combustibles, a través de un software especializado. Posteriormente, se seleccionó el sistema de tratamiento adecuado, considerando la capacidad de flujo de la corriente gaseosa que cada tecnología puede tratarResultados: Se determinó que la generación de COV es mayor en el área de cargaderos que en los tanques de almacenamiento, ya que estas corresponden a un 95 % y 5 %, respectivamente. En consecuencia, la propuesta del sistema de tratamiento de vapores de gasolina se enfoca en la zona de carga de combustible, con la selección de la condensación criogénica como tratamiento de recuperación no destructivo.Conclusiones: La estimación de tasa de emisiones fugitivas permitió tener una base para establecer una estrategia para la reducción de estas emisiones en pro de la salud de los trabajadores que están constantemente expuestos a ellas.Para disminuir las emisiones directas a la atmósfera durante la carga de las cisternas, se deben realizar los cambios necesarios para adaptarlos a un sistema hermético que permita enviar los vapores de gasolina que se generan por la presencia de producto residual en las paredes de los camiones y por la turbulencia que se provoca durante la carga del nuevo producto, a la unidad de recuperación de vapores que se instale.

Abstract
Nascimento, MA, Silva, DRP, Ribeiro, AS, Pina, FLC, Gerage, AM, Gobbo, LA, Mayhew, JL, and Cyrino, ES. Agreement between bioelectrical impedance and dual-energy x-ray absorptiometry to track changes in fat-free mass after resistance training in older women. J Strength Cond Res 34(6): 1700–1708, 2020—The aim of our study was to compare the agreement between bioelectrical impedance (BIA) and dual-energy X-ray absorptiometry (DXA) to track changes on fat-free mass (FFM) after a resistance training (RT) program in older women. Forty-three older women (65.2 ± 4.6 years, 59.5 ± 9.2 kg, 156.4 ± 6.0 cm, 24.3 ± 3.3 kg·m−2) participated in a RT intervention (12 weeks, 8 exercises, 2 sets, 10–15 repetitions, 3 nonconsecutive days per week). Fat-free mass changes were determined by a single-frequency BIA device (EQ1), 6 BIA prediction equations for older women (EQ2, EQ3, EQ4, EQ5, EQ6, and EQ7), and DXA. At pretraining, 3 equations overpredicted, and 3 underpredicted DXA FFM (F = 244.63, p < 0.001), although all equations had high correlations with DXA (r = 0.78–0.83). After training, 4 equations overpredicted and one underpredicted DXA FFM (F = 176.25, p < 0.001). Dual-energy X-ray absorptiometry detected significant gains in FFM (0.65 ± 0.82 kg; p < 0.05), as did EQ3 (0.55 ± 1.69 kg; p < 0.05), and EQ4 (0.61 ± 1.88 kg; p < 0.05), whereas the remaining equations did not indicate significant changes in FFM. Low correlations between FFM and equation change values suggest that single-frequency BIA-derived equations may not provide sufficient accuracy to track changes in FFM after 12 weeks of RT in older women.

Abstract
Chaouachi, A, Ben Othman, A, Makhlouf, I, Young, JD, Granacher, U, and Behm, DG. Global training effects of trained and untrained muscles with youth can be maintained during 4 weeks of detraining. J Strength Cond Res 33(10): 2788–2800, 2019—Global (whole-body) effects of resistance training (i.e., cross-education) may be pervasive with children. Detraining induces less substantial deficits with children than adults. It was the objective of this study to investigate the global responses to 4 weeks of detraining after 8 weeks of unilateral leg press (LP) training in 10–13-year-old, pre-peak-height-velocity stage boys. Subjects were randomly separated into 2 unilateral resistance training groups (high load/low repetitions [HL-LR] and low load/high repetitions [LL-HR], and control group). Assessments at pre-training, post-training, and detraining included dominant and nondominant limbs, unilateral, 1 repetition maximum (1RM) and 60% 1RM LP, knee extension, knee flexion, elbow flexion, and handgrip maximal voluntary isometric contraction (MVIC), and countermovement jump (CMJ). All measures significantly increased from pre-test to detraining for both training programs, except for elbow flexion MVIC with increases only with HL-LR. All measures except CMJ and handgrip MVIC significantly decreased from post-test to detraining, except for elbow flexion MVIC with decreases only with HL-LR. The dominant trained limb experienced significantly greater LP improvements (pre- to detraining) and decrements (post- to detraining) with LP 1RM and 60% 1RM LP. In conclusion, youth HL-LR and LL-HR global training effects of trained and untrained limbs demonstrate similar benefits (pre- to detraining) and decrements (post- to detraining) with detraining. The findings emphasize that training any muscle group in a child can have positive global implications for improved strength and power that can persist over baseline measures for at least a month.

Biodynamic agriculture grew steadily in the decades after Rudolf Steiner’s death, giving rise to an international organics movement by 1940. Three distinct groups of people spread the biodynamic impulse: “evangelists,” who actively promoted Steiner’s teaching; “translators,” who expressed the core ideas of biodynamics in non-anthroposophical language; and “allies,” who were primarily committed to other forms of organic practice. Thus, the organic movement was shaped by evangelist Ehrenfried Pfeiffer, translator Lord Northbourne, and allies Eve Balfour and J. I. Rodale. A generation later, it bore new fruit in the anti-pesticide impulse initiated by evangelists Marjorie Spock and Polly Richards and ally Rachel Carson.
A High Quality Genome for Mus spicilegus, a Close Relative of House Mice with Unique Social and Ecological Adaptations

Published: May 2018

Abstract
Genomic data for the closest relatives of house mice (Mus musculus species complex) are surprisingly limited. Here, we present the first complete genome for a behaviorally and ecologically unique member of the sister clade to house mice, the mound-building mouse, Mus spicilegus. Using read cloud sequencing and de novo assembly we produced a 2.50 Gbp genome with a scaffold N50 of 2.27 Mbp. We constructed &gt;25 000 gene models, of which the majority had high homology to other Mus species. To evaluate the utility of the M. spicilegus genome for behavioral and ecological genomics, we extracted 196 vomeronasal receptor (VR) sequences from our genome and analyzed phylogenetic relationships between M. spicilegus VRs and orthologs from M. musculus and the Algerian mouse, M. spretus. While most M. spicilegus VRs clustered with orthologs in M. musculus and M. spretus, 10 VRs with evidence of rapid divergence in M. spicilegus are strong candidate modulators of species-specific chemical communication. A high quality assembly and genome for M. spicilegus will help to resolve discordant ancestry patterns in house mouse genomes, and will provide an essential foundation for genetic dissection of phenotypes that distinguish commensal from non-commensal species, and the social and ecological characteristics that make M. spicilegus unique.

Abstract
The pyruvate dehydrogenase complex (PDH), that converts pyruvate to acetyl-coA, is regulated by pyruvate dehydrogenase kinases (PDHK) and phosphatases (PDHP) that have been shown to be important for morphology, pathogenicity and carbon source utilization in different fungal species. The aim of this study was to investigate the role played by the three PDHKs PkpA, PkpB and PkpC in carbon source utilization in the reference filamentous fungus Aspergillus nidulans, in order to unravel regulatory mechanisms which could prove useful for fungal biotechnological and biomedical applications. PkpA and PkpB were shown to be mitochondrial whereas PkpC localized to the mitochondria in a carbon source-dependent manner. Only PkpA was shown to regulate PDH activity. In the presence of glucose, deletion of pkpA and pkpC resulted in reduced glucose utilization, which affected carbon catabolite repression (CCR) and hydrolytic enzyme secretion, due to de-regulated glycolysis and TCA cycle enzyme activities. Furthermore, PkpC was shown to be required for the correct metabolic utilization of cellulose and acetate. PkpC negatively regulated the activity of the glyoxylate cycle enzyme isocitrate lyase (ICL), required for acetate metabolism. In summary, this study identified PDHKs important for the regulation of central carbon metabolism in the presence of different carbon sources, with effects on the secretion of biotechnologically important enzymes and carbon source-related growth. This work demonstrates how central carbon metabolism can affect a variety of fungal traits and lays a basis for further investigation into these characteristics with potential interest for different applications.

ADOPTING 21ST CENTURY COMPETENCIES FOR A TECHNICAL UNIVERSITY CURRICULUM
Authors: Iurina Maria , Gorlova Ekaterina 
Published: May 2018

Russian universities are involved in the global process of rethinking and remodelling of the higher educational system. They are expected to provide their students with a wide variety of skills, which are often referred to as "21st century competencies". Such skills as critical thinking, decision making, the ability to communicate effectively and solve problems through negotiation and collaboration are needed for success in study and careers. For the universities it means growing importance of making curriculum relevant, helping students learn how to teach themselves, and fostering creativity. This article explores the quality of learning in the Russian technical university and concludes that the current pedagogy has not adapted yet to address the challenges of the twenty-first century. The traditional approach, based upon a teacher-centred focus on rote learning still prevails. Through this research it was found that there are different pedagogical approaches that could develop different 21st century competencies by technical students. The article concludes with a discussion around some innovative teaching methods that make lessons more student-driven and motivating.

Published: May 2018

The recent reforms in the Latvian general education curriculum along with a school network reorganization have brought new attention to the issues related to a teacher education and the level of professionalism in everyday teaching work. Soviet-era education and work experience in diverse political and education systems (under the Soviet rule and after the restoration of independence) are factors that should be taken into account when analyzing the teacher in the citizenship education learning process. For the needs of this Paper, the authors used the data of the IEA ICCS 2016 (International Association for the Evaluation of Educational Achievement International Civic and Citizenship Study 2016) teachers who teach citizenship education-related school subjects (n=249) and their students (N=3224, Grade 8, average age from 13 to 14). To process the data, the authors usedclusters, correlations, regression analysis and descriptive statistics.The aim of this Paper is to study what the teacher is like in the process of citizenship education. The findings allow making two conclusions: First, the teacher’s personality, experience and networking skills plays an important role; Second, the popular assumption among both professionals and nonprofessionals that cooperation between an eighth-grade teachers and parents leads to a better student achievements is false.

CONSTRUCTIVE DEALING WITH ANXIETY AND ANGER AS AN ASPECT OF THE QUALITY OF LIFE OF MATURING GIRLS WHO PRACTISE TAEKWON-DO
Authors: Wąsik Jacek 
Published: May 2018

The quality of life, including the quality of life connected with health covers coping with difficult emotions and the ability of fulfilling aims, despite their deconstructive effects. Constructive dealing with emotions, such as anxiety and anger (i.e. that are considered to have negative character) makes a very important aspect of the quality of one’s life. The process of growing up is, to a large extent learning to cope with difficult emotions. In this work we are concentrating on one of the aspects of the quality of life connected with health-related effects of systematic physical activity performance, such as taekwon-do. One of the very important reasons of a positive influence of practising martial arts (and other forms of physical activity) on the quality of life is a beneficial impact of such an activity on a widely-understood psychophysical skills, dealing with anger and better coping with anxiety. In the light of contemporary knowledge (and old sources) taekwon-do cannot only mean physical activity, though, undoubtedly, it is a very important, key aspect of this activity. In the paper we present the results of our own research concerning the ways of dealing with anger and anxiety by the girls practising taekwon-do (with the inclusion of the period of practise). In the light of the our research girls and women who have practised taekwon-do for over 2 years are more effective in coping with the situations of the choice between different options (to choose from) if each of them has its positive and negative consequences. Maturing girls and young women who practise taekwon-do have better abilities of constructive coping with stressful situations, including reaction for the situations causing anxiety.

Published: May 2018

The relevance of the research is realized through the search for the music teacher’s activities that help to improve the process of music education while fostering the learner’s aesthetic and meaningful relationship to music. The object of the research is a music teacher’s activity of teaching music in general education school. The aim of the research is to analyse the improvement opportunities of a music teacher’s activity during music lessons in seventh-eighth grades in general education schools. The methods of the research include the analysis of scientific literature and documents of education; semi-structured interviews with music teachers; a written survey; quantitative and qualitative data analysis. According to the collected data, a variety of musical activities helps to develop learners’ inborn musical abilities, provide a favourable learning environment with an opportunity to develop the learners’ musicianship and presuppose their transferable skills. In this context, teachers’ active and creative musical involvement helps the learner to experience more positive emotions. Such a personal involvement and cooperation serve as a major condition for the improvement of the teachers’ musical activity. An inappropriate choice of the activities can lead to dissatisfaction and be the main reason for failure. The teachers’ participation in musical activities could encompass a number of music modes, which could create a more attractive and productive activity in the lesson: a teacher – a performer – a listener – a facilitator – a leader.

Published: May 2018

From OECD PISA Science test results presented in 2016 shows that in Latvia only 3,4% of students performance is in accordance to the 5th and 6th performance level (higher order cognitive skills (HOCS) measured), which is below OECD average. In Latvia from 2016 started Curriculum Development and Implementation project, which one of the priorities is student’s ability to apply HOCS (higher order cognitive skills) to improve these results. The development of deeper thinking (cognitive activity) is one of the most advanced skills in all subjects, including biology. In order to reduce the risks, it is necessary to analyze introducing new reforms the opportunities for students to develop HOCS through biology lessons and textbooks in current teaching and learning process. In previous researches it was found out that all items with context of 9th grade biology in the Latvia’s National level Science test (period 2015-2017) were measuring only low and average depth and no one was in high cognitive level as opposed to the PISA framework. It is required to study reasons of that more deeply. The research goal is to analyze cognitive depth of given tasks that students have the opportunity to do in the lessons of biology, biology textbooks from 7th till 9th grade and with 9th grade biology tasks in Latvia’s National level Science tests from years 2015 till 2017 and to compare these three cognitive depth results to the PISA 2015 Science framework. To find out cognitive depth of given tasks, there were analysed 31 samples of biology lessons and 6 biology textbooks for grades 7th till 9th.
