Is sauna bathing protective of sudden cardiac death? A review of the evidence

2019

Sudden cardiac death (SCD) is a global public health burden accounting for 15–20% of all deaths. Though established atherosclerotic risk factors explain a large proportion of the risk of SCD, these factors are often absent in a large proportion of SCD victims and the pathogenesis of SCD is still not fully established. It therefore appears that additional factors may be involved. Sauna bathing is a traditional Finnish activity that is mainly used for the purposes of relaxation and pleasure. Beyond its use for these purposes, sauna bathing has been linked with several health benefits. Emerging evidence suggests that sauna bathing is associated with reduced risk of adverse cardiovascular (CV) …

Chambered warm moist air eyelid warming devices – a review

2021

Background Eyelid warming is an important treatment for meibomian gland dysfunction (MGD). Specialized chambered devices, using warm moist air have been developed. Purpose To critically evaluate the literature on the safety and efficacy of chambered warm moist air devices in MGD treatment and pinpoint areas of future research. Methods PubMed and Embase were searched on 06 June 2021. The search term was ‘(warm OR heat OR steam OR goggle OR spectacle OR moist air) AND (meibomian OR MGD OR blepharitis OR eyelid OR dry eye OR DED)’. All relevant articles with available English full text were included. Results Eighteen articles assessing the application of chambered warm moist air eyelid warming…

Kids Inspire Kids for STEAM

2017

Abstract The goal of the Kids Inspiring Kids in STEAM (KIKS) project was to raise students' awareness towards the multi- and transdisciplinary connections between the STEAM subjects (Science, Technology, Engineering, Arts & Mathematics), and make the learning about topics and phenomena from these fields more enjoyable. In order to achieve these goals, KIKS project has popularized the STEAM-concept by projects based on the students inspiring other students-approach and by utilizing new technologies, tools, open educational resources, and everyday items and materials. Through the students-inspiring-other-students-approach, we have aimed to get participating students developing STEAM activitie…

Mathematics and Art Connections Expressed in Artworks by South African Students

2022

In this chapter, we examine a collection of drawings, and paintings from South African students between the ages of 10 to 17, that provide fresh and original perceptions to some already known topics, but also several unexpected connections between mathematics and art. These works reference classic math-art connections such as: golden ratio, spirals, infinity, and geometric figures; they also contain several personal reflections, unique discoveries and references to ethnomathematical connections within the African cultural heritage. To introduce their pieces and themselves, students shared their own interpretations of their artworks. These commentaries make possible the identification of cog…

Individual Creativity and Career Choices of Pre-teens in the Context of a Math-Art Learning Event

2021

A sample of 392 students (aged 12-13 years, M± SD: 12. 52% girls) completed a learning module integrating informal hands-on mathematics and arts activity (extending STEM to STEAM). Within a 140 minute workshop period participants worked with commercially available ‘4Dframe’ Math and STEAM learning toolkits to design and create original, personal and individual geometrical structures. Two science pedagogues acted as tutors supervising the process and intervened only when needed. A pre-/post-test design monitored individual creativity, relative autonomy, and career choice preference. Path analysis elaborated the role of creativity (measured with two subscales: act and flow), and it showed tha…

Chemical composition and antimicrobial activity of the essential oil from aerial parts of Micromeria fruticulosa (Bertol.) Grande (Lamiaceae) growing…

2007

The essential oil of aerial parts of Micromeria fruticulosa (Lamiaceae) growing wild in Southern Italy was obtained by hydrodistillation and analysed by GC and GC–MS. Sixty-one compounds, representing 91.3% of the oil, were identified. The major components were γ-terpinene (14.5%), β-caryophyllene (12.6%), p-cymene (8.9%), α-pinene (8.2%) and β-bisabolene (7.2%). The essential oil showed action mainly against Gram-positive bacteria. Copyright © 2007 John Wiley & Sons, Ltd.

Extraction Methods of Essential Oils From Herbs and Spices

2017

International audience; This chapter describes both conventional and non‐conventional extraction methods of essential oils (EOs) from herbs and spices. Although hydrodistillation, steam distillation and solvent extraction are the most applied methods, several non‐conventional technologies have been evaluated, especially in respect to EO recovery, and a great potential has been attributed to these non‐conventional methods. For instance, ultrasound, microwave, supercritical fluid, pulsed electric fields, ohmic‐heating and microwave (MW) extraction techniques applied alone or combined with other techniques are potent tools to obtain EOs in a 'green' way from natural resources such as aromatic …

Käyttäjien luoma sisältö digitaalisissa peleissä

2016

Käyttäjien luoma sisältö on kasvava ilmiö, mutta sen käyttöä peleissä on tutkittu vain vähän. Tutkielman tavoitteena on selvittää käyttäjien luoman sisällön merkitys peleille. Käyttäjien luomasta sisällöstä on hyötyä niin pelin kehittäjille, sisällönluojille kuin pelaajillekin. Sen mahdollistaminen säästää pelinkehitysbudjetissa, pidentää pelin ikää, kasvattaa pelin sisältömäärää, tiivistää peliyhteisöä ja tekee pelistä enemmän pelaajiensa näköisen. Se antaa myös sisällönluojille mahdollisuuden toteuttaa itseään. Käyttäjien luomaa sisältöä hyödyntävän pelin suunnittelussa on tärkeää miettiä sisällönluonnin ja jakamisen helpoksi tekemistä. Sisällönluontia varten tehdyillä työkaluilla, sisäll…

CONSIDERING VARIOUS STAKEHOLDERS’ VIEWS IN THE DESIGN OF A HYBRID STEM LEARNING ENVIRONMENT - PERCEPTIONS FROM FINLAND AND GREECE

2017

Raising young people’s interest in studies and careers related to science, technology, engineering, and mathematics (i.e., STEM) is an important societal concern both at European and global level. We argue that the creation of attractive and engaging STEM learning environments necessitates involvement of learners, educators, parents, and STEM professionals in their design. In this paper, we will present a study in which primary, lower and upper secondary school students, teachers, school directors, parents, and STEM professionals in Finland (n = 27) and Greece (n = 24) were invited in the participatory co-design of a hybrid (virtual, physical, formal, and informal) STEM learning environment…
