Published: May 2021

La investigación tuvo como objetivo determinar si los modos de comportamiento en el mundo laboral están condicionados por el hecho de pertenecer a una generación, o si es mayor el impacto de tener que adaptarse a un nuevo orden mundial; mediante un estudio de tipo mixto, corte transversal que, según la etapa, tuvo alcances descriptivo y relacional. Se aplicó las técnicas de la entrevista a profundidad y el censo a una población heterogénea conformada por 188 estudiantes de postgrado de una universidad pública de Buenos Aires, Argentina.
Los resultados demuestran que el hecho de pertenecer a una generación demográfica no determina las conductas, sino que las actitudes y valores son los que las determinan. Se concluyó que la actitud es un factor determinante para adaptarse a las nuevas tecnologías y retos laborales. Asimismo, se propuso un nuevo enfoque de paradigma no encontrado en la bibliografía.
Protocol for Local On-Site Dialysate Production for Continuous Renal Replacement Therapy during the COVID-19 Pandemic

Abstract

Key Points

Because dialysate production in a hospital is not commonly performed, the technique has not been generalized to commonly available materials.On-site dialysate production may be necessary when demand is high, as it was during the coronavirus disease 2019 pandemic.This technique can be easily and widely applied to most hospitals using commonly available materials.

AKI frequently occurs in patients with COVID-19, and kidney injury severe enough to require RRT is a common complication among patients who are critically ill. During the surge of the pandemic, there was a high demand for dialysate for continuous RRT, and this increase in demand, coupled with vulnerabilities in the supply chain, necessitated alternative approaches, including internal production of dialysate. Using a standard hemodialysis machine and off-the-shelf supplies, as per Food and Drug Administration guidelines, we developed a method for on-site dialysate production that is adaptable and can be used to fill multiple bags at once. The use of a central reverse osmosis unit, dedicated hemodialysis machine, sterile bags with separate ports for fill and use, and frequent testing will ensure stability, sterility, and—therefore—safety of the produced dialysate. The dialysate made in house was tested and it showed both stability and sterility for at least 30 hours. This detailed description of our process for generating dialysate can serve as a guide for other programs experiencing similar vulnerabilities in the demand versus supply of dialysate.
The Importance of technical analysis for improving performance in athletics in long distance running
Authors: Dobre Andreea Georgiana , Mereuță Claudiu , Grigore Florin Eduard 
Published: May 2021

It is well known that the level at which the performances in the sports competitions have come lately is also due to the improvement of the specific techniques by: studying the most intimate / hidden aspects of the running technique that provide insight into the level of influence of the muscle chains involved in each phase of the movement; knowledge of the biomechanical details that can improve the technique of the general run and the departures from the start. It is assumed that participation in high-performance competitions is possible by restructuring the training efforts during the annual training cycle, using increased proportionate efforts in the mixed and anaerobic area as well as the approach as a separate indicator of the compensatory effort, and in this restructuring an essential role could be played by the technical aspect of long runs. When we discuss the technique of athletics, we must consider two aspects which, depending on how well they are improved, influence the final result. This is the sample technique and the treadmill technique.

Published: May 2021

Flexibility is an essential quality for an athlete, which is why a high level of flexibility is required to increase efficiency and economy of movement, which interests all sports disciplines.The purpose of this scientific approach is to show that the development of static flexibility specific to foot techniques in karate, for practitioners between the ages of 14 and 18, is not done at random. The drive systems, applied within the programme proposed in this study for the development of flexibility, are subject to anatomically determined laws of motion, are functional and succeed in a methodical sequence.The experiment performed on karate practitioners - Shotokan emphasizes the importance of developing specific mobility which will allow them to execute foot techniques at a higher level and achieve outstanding performance.The application of the tests and the implementation of carefully selected drive systems that contribute to the development of mobility specific to karate techniques substantiates the working hypothesis and validates through its results the correctness of the experimental operation.

The acceleration of contemporary world events, global social, political and economic transformations that have changed traditions and ideologies into new forms adopted by young generations have also brought new content, methods and skills to the field of physical education and sport that have reformed the system and are able to respond to solving unknowns that have pushed to another stage the practice of sports activities.The development of information technology has attracted the lack of interest of young people for movement through forms of practice, known as sometimes unattractive.The purpose of this study is to argue the rethinking of the composition of physical education programs, the discovery of solid evidence based on the reasons for practicing physical sports, the presentation of models to follow and the adaptation of basic structures to human evolution.Assumption. In this study we tried to find out what are the elements that could motivate students to practice physical sports.The results we reached after the study confirmed that more and more students prefer to spend their free time with activities other than sports and those who still prefer movement choose activities that offer fun, play and recreation.
Considerations regarding the evolution of roller speed skating in Romania
Authors: Vaida Marius 
Published: May 2021

The fact that in Romania, in the last years, this sport has experienced some regression in terms of number of practitioners is trying to establish whether this affects the achieved results, as the vast majority of the clubs that have speed skating sections still work. Sport selection is of particular importance in achieving the best sports performance, which should be carried out on a continuous basis.This study aims to highlight the evolution of speed skating in our country between 2014-2019, for the senior category, at the national roller speed skating Championship. The events that were targeted in this study are 500m, 1000m, 1500m and 3000m seniors (boys and girls) competitions. The first 3 (or 2, depending on the situation) results per year investigated were collected. The research methods used are: Bibliographic method, data collection and graphical method.From the data shown above it can be noted that, with the exception of the years 2015/2016 (when poor results are most frequently shown) and in two cases during 2018, the achieved results were improved in both girls and boys, in some cases the achieved progress being significant.Although speed skating in Romania is not a sport as publicized as other sports branches, the results are on an ascending line, in the process of improving, which shows that trainers in our country have a level of knowledge comparable to other countries with tradition in the world, increasing funding and attracting sponsorship is one of the factors that can accelerate the advancement of athletes by increasing cantonal numbers, using state-of-the-art equipment, using effort supporters according to their preparation time and age etc.

Abstract
Noncontact micromanipulation techniques are necessary for micromachine technology, biotechnology, materials processing, and so on. By using a bolted Langevin transducer and a reflector, one can trap small objects in air at nodes of sound pressure in a standing wave field, but such a technique requires high-voltage drive and careful tuning to achieve resonance. In this study, a large number of small ultrasonic speakers were placed on the inner surface of a semicylinder to form a strong sound field in the focus line. We showed that the pressure node can be moved, and thus the small object, along the focus line simply by switching the driving ultrasonic speakers without using complex electronics. We also showed that the object can be trapped and manipulated even at a duty ratio of 50% in tone burst waves. The above results are discussed by showing the experimental and calculated sound pressure distributions.

Este estudo se debruça sobre os downshifters - indivíduos que fazem a opção por desacelerar seus ritmos de vida, buscando equilíbrio entre trabalho e lazer e estilos de vida mais frugais de forma a minimizar os efeitos das sociedades industriais capitalistas urbanas. Explora um tipo particular de comportamento em um estrato social específico - um grupo social formado por famílias que têm filhos em uma escola Waldorf, em Florianópolis, Brasil. Foi possível perceber que os aspectos formadores de movimento altera não só indivíduos, mas também as famílias inseridas no espaço educacional que se apresenta como resistência ao sistema educacional tradicional. Os Waldorf assumem premissas do downshifting. Sob a ótica da contracultura, formam um grupo coeso de classe média que tende a restringir sua rede social àqueles que compartilham o mesmo estilo de vida; suas ações cooperativas fomentam sentimentos de pertencimento e solidariedade que ajudam a legitimar estilos de vida alternativos em uma sociedade consumista.

Abstract
The Zwicky Transient Facility (ZTF) has been observing the entire northern sky since the start of 2018 down to a magnitude of 20.5 (5σ for 30 s exposure) in the g, r, and i filters. Over the course of two years, ZTF has obtained light curves of more than a billion sources, each with 50–1000 epochs per light curve in g and r, and fewer in i. To be able to use the information contained in the light curves of variable sources for new scientific discoveries, an efficient and flexible framework is needed to classify them. In this paper, we introduce the methods and infrastructure that will be used to classify all ZTF light curves. Our approach aims to be flexible and modular and allows the use of a dynamical classification scheme and labels, continuously evolving training sets, and the use of different machine-learning classifier types and architectures. With this setup, we are able to continuously update and improve the classification of ZTF light curves as new data become available, training samples are updated, and new classes need to be incorporated.

Abstract
The radius valley, a bifurcation in the size distribution of small, close-in exoplanets, is hypothesized to be a signature of planetary atmospheric loss. Such an evolutionary phenomenon should depend on the age of the star–planet system. In this work, we study the temporal evolution of the radius valley using two independent determinations of host star ages among the California–Kepler Survey (CKS) sample. We find evidence for a wide and nearly empty void of planets in the period–radius diagram at the youngest system ages (≲2–3 Gyr) represented in the CKS sample. We show that the orbital period dependence of the radius valley among the younger CKS planets is consistent with that found among those planets with asteroseismically determined host star radii. Relative to previous studies of preferentially older planets, the radius valley determined among the younger planetary sample is shifted to smaller radii. This result is compatible with an atmospheric loss timescale on the order of gigayears for progenitors of the largest observed super-Earths. In support of this interpretation, we show that the planet sizes that appear to be unrepresented at ages ≲2–3 Gyr are likely to correspond to planets with rocky compositions. Our results suggest that the size distribution of close-in exoplanets and the precise location of the radius valley evolve over gigayears.

Published: May 2021

This study aimed to evaluate the microbiological quality of the water of four ponds used for irrigation on the Lagoa do Sino Farm, as well as to perform the genotypic characterization of virulence factors in Escherichia coli isolates. Sampling was conducted for 11 months, between 2015 and 2016. Samples were analyzed for the presence of thermotolerant coliforms, E. coli and heterotrophs. DNA was extracted from E. coli isolates, followed by genotypic characterization by polymerase chain reaction. Agricultural activities and pesticides used in the sampling period were documented in order to assess possible relationships between agricultural activities and microbiological water quality. The absence of suitable riparian vegetation around all the ponds was observed, benefiting the entry of organic matter and contaminants in the water body. A high index of thermotolerant coliforms in some months indicated the possibility of the transmission of pathogenic microorganisms in these ponds. The values found in some months were above the regulatory limits for water potability and water intended for irrigation. The agrochemicals used in the period seem to influence the results obtained. All 17 E. coli isolates showed at least one of the virulence genes estA, stx1, stx2, and aatA, indicating enterotoxigenic, enterohaemorrhagic or enteroaggregative nature. The presence of E. coli in the waters may be associated with the presence of animals. The water samples analyzed are not suitable for irrigation of vegetables that are consumed raw and/or low lying fruits ingested without skin removal. It is essential to broaden the control of the use of chemicals, as well as the preservation of riparian vegetation to improve the quality of water used in the farm's agricultural activities.
