The study reported in this paper aims to show how Croatian lower-secondary mathematics teachers coped with remote education during the lockdown necessitated by the Covid-19 pandemic. The research design refers to the case study of six teachers. On five occasions, the teachers were interviewed about the organisation of their virtual classrooms, forms of assessment, and utilisation of (digital) teaching resources from the beginning of March until the end of June 2020. The study results showed that social parameters were prominent factors in the decision-making of many teachers regarding teaching remotely. For example, the teachers always put students’ needs first: they were accessible almost all day to their students, they tried not to overload students and provided daily feedback on their work. In addition, the teachers in the study raised the issue of academic dishonesty in remote education – the digital environment made cheating easier and meant that the usual assessment formats became unfeasible. Although the findings provide insight into the work of teachers during a pandemic, a larger sample would provide generalisations about the changes in workload that mathematics teachers experienced during remote education.

The purpose of this study has been to determine the views of elementary mathematics teachers on the applicability of modeling in mathematics courses. A case study was conducted with 17 elementary mathematics teachers working in various provinces in Turkey. An interview form consisting of open-ended questions was designed for the purpose of collecting data, which was obtained through semi-structured interviews. From the categories constituting the themes developed via the views of the teachers, four major conclusions and one minor conclusion were reached at the end of the study. Study results showed that the elementary mathematics teachers’ knowledge of the process and teaching performance had an impact on their views of the applicability of modeling.

Agile methods have taken software development by storm but have been primarily applied to projects in what is referred to as the “agile sweet spot,” which consists of small collocated teams working on small, non-critical, green field, in-house software projects with stable architectures and simple governance rules. These methods are being used more and more on large projects, but little documentation is available in the academic literature. This article investigates the adoption and adaptation of agile methods for use on large projects in large organizations. The empirical study is based first on case studies, followed by a survey to validate and enrich the case study results. The results are somewhat paradoxical in that some features are common to almost all observations, whereas others show extreme variability. The common features include use of Scrum methodology and agile coaches, as well as the non-respect of the agile principle of emergent architecture.

Pulmonary Tuberculosis is an infectious disease that attacks the lung parenchyma, caused by mycobacterium tuberculosis. This disease can also spread to other body parts such as meninges, kidneys, bones and lymph nodes of pulmonary TB is a big problem for developing countries including Indonesia As most developing countries do. Almost all adult residents have been infected by TB bacilli in easy times, since most pulmonary TB disease in this country is caused by bacilli that undergo reactivity Goals : To know the description of the patient's knowledge of TBC Lung prevention transmission of pulmonary tuberculosis infection in the internal room At Santa Elisabeth Hospital Medan. Method: type of rancanagn case study used is descriptive number of subjects is as much as 9 0rang data collection in the form of questionnaires after that done scoring data is presented in the form of tables and distribution frequency Results: From the case study the frequency distribution of respondents based on the use of the questionnaire. From the case study conducted (seen in table 4.1) that more male sex is 9 people (100%) and female 0 (0%). From this case study, the result is good.. Conclusion: Based on the results of the case studies described above, the authors conclude the case study results that the level of education greatly influences the patient's knowledge in preventing transmission of TB disease. It is evident that the level of education of the upperand upper-secondary patients with the highest proportion of case studies ( 55,5%) know the mode of transmission of infection prevention.

The genre of annotated verse represents an under-explored form of transporting romanticism. In annotated, locodescriptive poems like those in Anna Seward's Llangollen Vale, readers are invited to read not only the spatiality of the landscapes depicted in the verse but also the landscape of the page itself. Seward's poems, with their focus on understanding geographical, political, and historical spaces both real and imaginary, provide geocritical insight into poetic productions of the early Romantic era. Likewise, geocriticism offers a fresh and useful – even necessary – analytic approach to such poems. I adopt Anna Seward as a case study in annotated verse and argue that attending to the materiality and paratextuality of her work allows us to access the complexities of her poetry and prose as well as her position within the wider framework of transporting Romanticism.

Abstract: Presented from an ArtScience practitioner's perspective, this paper provides an overview of Svenja Kratz's experience working as an artist within the area of cell and tissue culture at QUT's Institute of Health and Biomedical Innovation (IHBI). Using The Absence of Alice, a multi-medium exhibition based on the experience of culturing cells, as a case study, the paper gives insight into the artist's approach to working across art and science and how ideas, processes, and languages from each discipline can intermesh and extend the possibilities of each system. The paper also provides an overview of her most recent artwork, The Human Skin Equivalent/Experience Project, which involves the creation of personal jewellery items incorporating human skin equivalent models grown from the artist's skin and participant cells. Referencing this project, and other contemporary bioart works, the value of ArtScience is discussed, focusing in particular on the way in which cross-art-science projects enable an alternative voice to enter into scientific dialogues and have the potential to yield outcomes valuable to both disciplines.

Механизм терапевтического действия мультипотентных мезенхимных стволовых клеток (ММСК) на облученный организм в последнее время вызывает повышенный интерес исследователей. В качестве активного участника паракринного механизма реализации этого эффекта предлагают рассматривать внеклеточные везикулы, секретируемые практически всеми клетками живого организма. Цель работы: выделить и охарактеризовать внеклеточные везикулы, продуцируемые стволовыми клетками различной природы. Материалы и методы. Суспензии внеклеточных везикул, выделенных по модифицированному протоколу дифференциального центрифугирования из культуральных жидкостей от культур ММСК костного мозга человека 2-го пассажа и ММСК жировой ткани крысы 4-го пассажа, были проанализированы методом просвечивающей электронной микроскопии и методом анализа траекторий наночастиц. Результаты. Исследование показало наличие в обоих образцах микрочастиц размерами до и около 100 нм, однако процентное содержание частиц разных размеров в суспензии различалось для двух анализируемых типов клеток. Заключение. Полученные результаты могут свидетельствовать о специфике секреции, обусловленной клеточным типом. A mechanism of the therapeutic effect of multipotent mesenchymal stem cells (MMSC) on irradiated body has recently arisen much interest of researchers. Extracellular vesicles (EVs) secreted by almost all cells of a living organism were suggested to actively contribute to the paracrine mechanism of this effect. The aim of the study was isolation and characterization of extracellular vesicles produced by various types of stem cells. Materials and methods. Suspensions of EVs were isolated from culture media of passage 2 human bone marrow-derived MMSC and passage 4 rat adipose tissue-derived MMSC using a modified protocol of differential centrifugation and then studied using transmission electron microscopy and nanoparticle tracking analysis. Results. The study showed the presence of microparticles with a size of >100 nm in the examined samples. However, the percent content of particles with different sizes in the suspension was different in two analyzed types of cell culture. Conclusion. The study results might reflect a specificity of secretion determined by the cell type.

Abstract In this paper, we propose a new methodology and test system to enable the early detection and precise localization of Time-Dependent-Dielectric-Breakdown (TDDB) occurrence in Back-End-of-Line (BEOL) interconnection. The methodology is implemented as a novel Integrated Reliability Test System (IRTS). In particular, through our methodology and test system, we can easily synchronize electrical measurements and emission microscopy images to gather more accurate information and thereby gain insight into the nature of the defects and their relationship to chip manufacturing steps and materials, so that we can ultimately better engineer these steps for higher reliable systems. The details of our IRTS will be presented along with a case study and preliminary analysis results.

Radical subject acceleration, or moving students through a subject area faster than is typical, including skipping grades, is a widely accepted approach to support students who are gifted and talented. This is done in order to match the student’s cognitive level and learning needs. This case study explored radical subject acceleration for gifted students by focusing on one school’s response to the learning needs of a ten year old mathematically gifted student. It provides insight into the challenges, accommodations and approach to radical subject acceleration in an Australian school. It explored the processes and decisions made to ensure that a gifted student’s learning needs were met and identified salient issues for radical subject acceleration. Lessons learned from this case study may be helpful for schools considering radical acceleration.
