Mathematical modeling of the position of the blocks at the bottom of the waterboard when fixing the wakeboard mast
Authors: Борисова В.А. 
Published: February 2022

Исследуется статическая модель нагрузок в мачте, тросах и блоках фиксирующих ее положение. В отличие от имеющихся способов установки, при которых вместо блоков используются сваи, расположенные на берегу и однозначно фиксирующих мачту для вейк-борда, в рассматриваемом случае нет возможности установить сваи. Поэтому блоки устанавливаются непосредственно в воду и ничем ко дну не прикрепляются. Фиксация происходит за счет силы трения между блоком и дном водоема, силы тяжести. Статическое равновесие рассматривается при предельных динамических нагрузках, которые были заданы в постановке задачи.
A static model of loads in the mast, ropes and blocks fixing its position is investigated. Unlike the existing installation methods, in which instead of blocks, piles are used, located on the shore and uniquely fixing the mast for the wakeboard, in this case it is not possible to install the piles. Therefore, the blocks are installed directly into the water and are not attached to the bottom by anything. Fixation occurs due to the force of friction between the block and the bottom of the reservoir, the force of gravity. Static equilibrium is considered at ultimate dynamic loads, which were specified in the problem statement.

Nos últimos anos a qualidade da água e do tratamento de esgoto no Brasil está em evidência e ampla discussão, devido aos diversos casos de contaminação por cianobactérias e agentes patógenos, dando destaque neste estudo: a Geosmina, o ZikaVirus e a COVID-19, que impactam os corpos hídricos. O objetivo deste pauta-se no debate da atual legislação e agências reguladoras que classificam a qualidade da água, interpretando critérios para a preservação da vida aquática, a conservação das áreas que circundam os rios e seus possíveis desdobramentos para a saúde humana. A metodologia está alicerçada na revisão literária em sites nacionais e internacionais, em órgãos e instituições públicas, definiu-se o IVA – Índice da Preservação de Vida Aquática (CETESB, 2017a/b) como estratégico na preservação do ecossistema aquático e provendo água potável para o consumo humano. Constatou-se como resultados: A diversidade de 60 agências controladoras em todo o país desestimula uma centralidade de dados e controle. A ANA (2021) somente responsabiliza-se em analisar: pH, oxigênio dissolvido, condutividade e temperatura, sem dispositivos de controle para evitar contaminações, e em destaque: a CEDAE em repetidos episódios de contaminação por geosmina no Rio Guandu, que comprovama eutrofização deste corpo d’água e a má qualidade da água fornecida ao consumidor, evidenciada por odor e sabor desagradáveis.

O uso e cobertura da terra compreende as diferentes estruturas modeladas a partir de forças de ordens natural e antropogênica. Esse tem sido um dos atributos mais utilizados para monitoramento e planejamento ambiental. O objetivo do presente estudo foi analisar as mudanças espaço-temporais do uso e cobertura da terra na bacia hidrográfica do rio Pontal, localizada no estado de Pernambuco. Para isso, foram empregadas técnicas de geoprocessamento e sensoriamento remoto utilizando classificação supervisionada em imagens orbitais dos satélites Landsat 5 e 8. Para obtenção de pontos de controle optou-se por utilizar as informações do Google Earth Pro, que possui um banco com imagens de alta resolução espacial e assim possibilita o reconhecimento real da área. Os resultados encontrados indicaram, de modo geral, que a metodologia se mostrou viável no sentido de detectar as classes de uso e cobertura da terra encontradas ao longo da área de estudo. A bacia do Pontal possui hoje menos água disponível no seu balanço hídrico para os diferentes usos e sustentabilidade ambiental devido as mudanças climáticas globais e mudanças no uso e ocupação do solo. As técnicas empregadas para o mapeamento do uso e cobertura da bacia hidrográfica do rio Pontal se mostraram consistentes no sentido de representar a variação espacial e temporal da vegetação na referida unidade.

Published: February 2022

Background: Continuing professional development for nurses is internationally recognised as a key factor in improving quality of care, career progression, job satisfaction and professionalization. Meeting the global and national challenge of Universal Health Coverage will require a flexible and skilled workforce. Since nurses are the backbone of health care in Nepal, their professional development is a key contribution to this task.
Objective: To explore the views of senior nurses on the need and opportunities for continuing professional development in nursing in Nepal and current barriers to its development.
Methods: Purposive sampling was used to identify participants and semi-structured interviews were conducted until saturation was reached. Interviews were transcribed verbatim and analysed using thematic analysis. 19 senior nurses, female (n=17) and male (n=2) working across the sector as clinicians, teachers and managers in Nepal participated in this study.
Results: Analysis revealed several themes and subthemes, including: the conceptualisation of CPD in Nepal; provision and funding; barriers – fiscal, political and geographical challenges; and future priorities which included a discussion around basic skills versus advanced practice.
Conclusions: The study provides an overview of opportunities and challenges for equitable access to continuing professional development in Nepal. Our findings illuminate the need for nurse leaders to work with policy makers and nursing organisations to establish the priorities for continuing development in light of increasing demand and expectations of health services.

The respondents indicated both the positive and negative aspects of distance learning. The first group comprised mainly aspects related to saving time, money and the flexibility of this form of learning, while the other group included aspects of a social and health nature, related to shortcomings in self-study and evaluation of the learning process.
Higher Education Employees’ Workplace Learning Within Three Schemes of International Mobility
Authors: Rojek Marcin , Leek Joanna 
Published: February 2022

Studies on the educational dimension of international mobility discuss the implications of academic, international mobility in general, or focus mainly on students’ mobility. There is, however, an insufficient number of studies that focus on the mobility of higher education staff, particularly in relation to learning. Each year, studies on the impact of mobility are published by the European Commission, but this does not provide an overview of how adult learning occurs within mobility and how mobility affects the lifelong learning of higher education employees. The purpose of this paper is to describe and explain HE employees’ learning characteristics in the course of three types of mobility: traditional, blended and digital. The study was conducted with the participation of 103 staff members of European Universities from 17 countries. We claim that the three mobility schemes studied here are different ways of experiencing the world and learning. Therefore, they should be implemented in parallel, and not perceived as alternatives.
