The market for electric bicycles has grown extremely and developed rapidly in recent years. To enter such a market with a new product, the development process has to be fast, and throughout the process, feedback from future potential customer(s) should be sought in order to achieve the best possible market acceptance. The article presents the design process of a pedelec e-bike central drive system

We are surrounded by various chemicals, both naturally occurring and synthetically produced. Some, but not all, chemicals can be hazardous for human health following exposure, especially for vulnerable population groups including children, adolescents, and pregnant women. The increased use and production of chemicals have contributed positively to society in numerous ways, while also resulting in

The aim of this work is to investigate the presence of airborne SARS-CoV-2 in corridors of infection wards, and gain more detailed size information of SARS-CoV-2-containing aerosols. Associations between SARS-CoV-2 presence and relative humidity and/or temperature in the facilities is also explored.

The difference from 4 to 6 σ in the Hubble constant (H0 ) between the values observed with the local (Cepheids and Supernovae Ia, SNe Ia) and the high-z probes (Cosmic Microwave Background obtained by the Planck data) still challenges the astrophysics and cosmology community. Previous analysis has shown that there is an evolution in the Hubble constant that scales as f (z) = H0/(1 + z)η, where H0

Several clusters and individual cases of acute hepatitis have been reported in the US, Europe and recently in Asia and Central America since October 2021. A laboratory investigation of the common viral hepatitis agents (HAV, HBV, HCV, HDV and HEV) yielded negative results prompting the use of the term “acute non HepA-E hepatitis” to describe this condition. The cases were characterized by the mani

Energy stands in the focal point of reducing the emissions. To reach the Paris Climate Agreement goals requiring carbon neutrality by the middle of this century, the emissions would need to be halved every ten years. The energy transition ahead thus encompasses a huge societal change, urging to view the change in a framework integrating technology, economics, policies and social aspects. Oxford Op

This study critically engages with the knowledge produced in the field of gender-based violence (GBV) in the context of migration. The focus is specifically on empirical studies that look at women whose immigrant status is precarious, which means that their pathway to citizenship is uncertain and dependent on others. Some examples are migrant women students, asylum claimants and refused asylum cla

Byggbranschen står inför en ny fas. Klimatförändringar och befolkningsökningen ger ökade påtryckningar till att bygga fler bostäder samt att fler kravs ställs på miljövänligare och energieffektivare byggnader. Under en modern bostads livstid råder dess högsta klimatbelastning under produktions- och byggskedet. En lägre klimatpåverkan eftersträvas och därmed behöver byggmetoderna utvecklas. Betong

WUI-NITY is a computer modelling program for wildfire evacuation simulations. This thesis examines the applicability of WUI-NITY to locations in Sweden. The program was tested at example locations representing the Swedish landscape. The objective of this work was both to examine the application of the model, but also to produce a process by which the model might be applied – highlighting challenge

Flera idrottsforskare understryker språkets roll i undervisning i skolämnet Idrott och hälsa (Larsson & Karlefors, 2015; Nyberg & Larsson, 2014; Schenker et al., 2019), och ämnesspråket har påståtts vara svagt inte minst i de delar som hör samman med hälsa (Redelius et al., 2009; Schenker, 2018). I denna artikel presenteras resultaten av en pilotstudie av ämnesspråket i skolämnet Idrott oc

Torslandacontainern: An ethnological study of solidity on four wheels. In a modern social landscape where high technology progression changes human-material relationships, the way we value durability, lifespan and capacity of the objects we consume alters. When ordinary daily life centers towards digital spheres our contact with objects formerly valued as rigid and solid becomes increasingly alie

This chapter focuses on recent policies adopted by the Swedish government in its management of unaccompanied children, and asks what the implications are for the concerned children’s rights. Focusing on conditions for rights, the chapter identifies three tensions which illustrate spaces for rights claiming: the boundary between who is a child and who is an adult, the division of responsibility bet

Humanitarian considerations in the Swedish asylum process. A study of the migration authorities’ balancing act between solidarity and inequality. Medical certi cates are becoming increasingly important as a basis for asylum assessments. Using examples from 24 asylum decisions concerning children and their families, the present article discusses how the Swedish Migration Agency and the Migration Co

An established negative association between socio-economic status (SES) and divorce has applied to most Western nations since 1960. We expected a positive association between SES and divorce for low-divorce contexts historically because only individuals in higher social strata had the resources to overcome barriers to divorce. According to Goode’s socio-economic growth theory, this relationship wa

Using patent data for a panel sample of European companies between 1995 and 2016 we explore whether the inventive success in Artificial Intelligence (AI) is related to earlier firms’ innovation in the area of Information and Communication Technology (ICT), and identify which company characteristics and external factors shape this performance. We show that AI innovation presents strong dynamic retu
