In hot climates, achieving a good indoor environmental quality (IEQ) in existing buildings is important especially with climate change challenges as future heat waves will increase in frequency, duration, and intensity. In educational buildings, there is much more focus on the IEQ parameters and the interactions among them that need to be in line with the continuously changing learning environment

In this contribution, we analyse scenarios of advanced wastewater treatment for the removal of micropollutants. By this we refer to current mainstream, broad spectrum processes including ozonation and sorption onto activated carbon. We argue that advanced treatment requires properly implemented tertiary (nutrient removal) treatment in order to be effective. We review the critical aspects of the ma

Background: Despite the advancement of electrocardiogram (ECG) monitoring methods, the most important factor influencing diagnostic yield (DY) may still be monitoring duration. Ambulatory ECG monitoring, typically with 24–48 hours duration, is widely used but may result in underdiagnosis of rare arrhythmias. Aims: This study aimed to examine the relationship between the DY and monitoring duration

Monitoring agricultural crops is of paramount importance for preserving water resources and increasing water efficiency over semi-arid areas. This can be achieved by modelling the water resources all along the growing season through the coupled water–surface energy balance. Surface albedo is a key land surface variable to constrain the surface radiation budget and hence the coupled water–surface e

OBJECTIVE: To investigate the value of ultrasonographic data in predicting total knee replacement (TKR).DESIGN: Data from the Musculoskeletal Pain in Ullensaker study (MUST) was linked to the Norwegian Arthroplasty Register to form a 5-7 year prospective cohort study of 630 persons (69% women, mean (SD) age 64 (8.7) years). We examined the predictive power of ultrasound (US) features, i.e. osteoph

PurposeDrylands account for 47.2% of land area and contain 15.5% of global carbon (C). However, the variation in organic and inorganic C stocks across latitudinal gradients in arid and semiarid shrubland ecosystems remains understudied, and we lack in-depth understanding of the main drivers of C variation at this spatial scale.MethodsHere, we sampled soils from 95 sites across a latitudinal gradie

ABSTRACT: Radiation dosimetry is central to virtually all radiation safety applications, optimization, and research. It relates to various individuals and population groups and to miscellaneous exposure situations-including planned, existing, and emergency situations. The International Commission on Radiological Protection (ICRP) has developed a new computational framework for internal dose estima

The world is slowly moving towards a more environmentally friendly mindset and many companies, such as Tetra Pak® have followed this lead by producing more environmentally friendly products and developing better materials with less environmental impact. To accommodate these requirements, it is important that the package is recyclable. For a carton this is defined by the repulpability, i.e., the ab

Glioblastoma (GBM) is the most aggressive type of primary brain tumours in adults and accounts for 49.1% of the cases. Most of the cases are recorded in elderly patients, but GBM affects people of all age groups. Till date no cure has been found. Previous data has suggested that pericytes might influence tumour invasion by interacting with tumour cells by the secretion of or interaction with extra

Enzymes are often considered a green approach next to conventional fossil-based chemicals helping us on the margin towards a low-impact society. While enzyme catalysed reactions are low environmental impact technologies, their production is not. In this study, a comparative life cycle assessment of different recombinant enzyme manufacturing strategies quantifies and evaluates the contribution of d

Klimatförändringar är en av de största utmaningar som vi har idag globalt, och skogsbruket spelar en vital roll i kampen mot dessa förändringar. Genom att förstå och reglera brukandet och förvaltningen av våra skogar kan vi bidra till att minska koldioxidutsläppen och kan då öka upptaget av växthusgaser från atmosfären till skog och mark. Ett viktigt verktyg för att åstadkomma detta är LULUCF-föroThe European Union (EU) aims to increase the overall carbon sink through the 2030 climate and energy policy framework, which includes the newly reviewed instrument and regulation of Land use, land use change and forestry (LULUCF). The regulation is considered an important component in the EU climate mitigation strategy which aims to manage and track the greenhouse gas emissions and removals in sec

Barnfridsbrottet infördes i svensk rätt år 2021, med ett starkt rättspolitiskt motiverat perspektiv – att skydda och stärka ställningen för barn som tvingades bevittna våld mellan närståendepersoner. Innan bestämmelsen trädde i kraft i svensk lagstiftning fanns det inte något annat skydd. Av den anledningen redogörs detta kort för genom uppsatsen, för att ge läsaren en förståelse om hur bestämmelsThe child protection offense was introduced into Swedish law in 2021, with a strong legal policy perspective - to protect and strengthen the position of children who were forced to witness violence between close persons. Prior to the entry into force of the provision in Swedish law, there was no other protection. For this reason, this is briefly described throughout the paper, to give the reader a

The goal of this master thesis was to identify an alternative to shaft encoders as means of achieving accurate motor velocity and position control for sliding door systems. While the company had previously explored methods like using backEMF, this thesis investigates counting voltage ripples during the commutation process in a brushed DC motor. During commutation, one or two pairs of commutator se

This thesis deploys ethnographic tools in a qualitative case study to explore the internet community, Female Dating Strategy (FDS). As narratives surrounding the “crisis of masculinity” are popularised within politics and mainstream media, the objective of research becomes to scrutinise these conceptualisations. This thesis does so by focusing on the field of intimacy and sexuality, by raising the

Styrning av partiklar med ljud och intelligenta algoritmer Det här examensarbetet handlar om att styra små partiklar i vätska utan att röra vid dem, med hjälp av ljud. Genom en teknik som kallas multimodal akustofores kombineras flera olika ljudvågor för att noggrant kunna påverka partiklarnas rörelser. Metoden är särskilt intressant inom biomedicin, till exempel vid analys av enskilda celler ellThis thesis explores a range of control algorithms for multimodal acoustophoresis, the process of manipulating particles in a fluid by simultaneously using several acoustic modes. The aim of the algorithms is to precisely guide particle trajectories in acoustofluidic systems, motivated by the demand for non-invasive, scalable manipulation techniques in biomedical applications such as single-cell a

New perspectives on how to best market your brand or products is an ever changing subject. A seemingly unnoticed development in the eyes of ordinary people has been that marketing psychology has become more and more potent in the industry of marketers and brand developers. Benefitting from unconscious behaviors and manipulation has created tools for companies and organizations that this paper is s

I väpnade konflikter så väl som i fredstid har förekomsten av våldtäkter och dess utbredda straffrihet fördömts av FN och förbud mot detta har konsekvent erkänts inom det internationella samfundet. Denna ståndpunkt är dock en för- hållandevis ny strävan. Den sena reaktionen på de krigsrelaterade våldtäk- terna är delvis en konsekvens av att våldtäkt historiskt präglats av myter. My- ter så som attRape and other forms of sexual violence committed with impunity during armed conflicts as well as peacetime has been condemned by the UN and the international community. However, this position is a relatively new. The late reaction to the war-related rapes is partly a consequence of the fact that rape has historically been the subject of myths. Myths such as that rapes represent an inevitable resu
