The district heating sector in Sweden is today facing several challenges due to competition from other heating alternativesas well as decreasing heat demand in buildings. To increase its competitiveness, the district heating companieshave to find ways to keep their production costs at a more or less constant level. One way of doing this is to increasethe efficiency of the district heating systems.The district heating sector in Sweden is today facing several challenges due to competition from other heating alterna-tives as well as decreasing heat demand in buildings.

High levels of nitrogen (N) deposition might result in a transition from N to phosphorus (P) limitation in high latitude forests. Thiscould have fundamental consequences for forest production, nutrient acquisition and nutrient leaching.I studied a Norway spruce forest in a region of high N deposition in southwest Sweden and added N, P or N+P to force thesystem to N or P limitation. I studied tree

The overall aim was to investigate informal caregivers providing care for older persons with dementia (≥ 65 years of age) in eight European countries. Focus was on their experiences of formal care, access to support and factors that were associated with caregivers’ psychological well-being and burden. Caregivers’ experiences of formal care were investigated in a qualitative study with four focus g

Placing concrete using a truck-mounted pump is a common construction method, enabling pouring of large volumes of concrete in a highly efficient way. However, the method is associated with unfavorable working conditions due to the need for manual handling of the end-hose. The hose-man are exposed to hazardous and poor working conditions. This paper reports on efforts to develop a robotic system fo

Popular Abstract in English A handful of diseases-causing pathogenic microorganisms claim millions of lives worldwide each year, mainly due to limited diagnostic capabilities. The lack of simple, cost-effective, sensitive and rapid on-site diagnostic tools lead to delays in the diagnoses with a subsequent lag in treatment, which in turn can result in serious complications or even loss of lives. Fast and sensitive detection of pathogenic microbial cells is a highly important task in medical diagnostics, environmental analysis and evaluation of food safety. Accordingly, the idea of microorganism identification by the recognition of specific DNA sequence using electrochemical technique is one of the leading researches in the development of diagnostic devices. In other words, it should only

The aim of this paper is to provide insights into, and perspectives on, the transformation of mindsets for logisticians. We argue that by exploring paradoxes inherent in the efficiency-focused paradigm of today, a strategic mindset can emerge in which central logistics management issues can be addressed, understood, and dealt with in order to enhance supply chain effectiveness and innovation. Base

The work of stage actors has long been used as a simile for every day role playing, generating theoretical concepts to describe how people work to pre-sent themselves in general and how they manage their emotions in particular. Building on this tradition, this article analyses professional stage actors’ deliberate emotion management as an embodied professionalisation process, focusing the relation

In secondary-school English-as-a-foreign-language (EFL) classrooms worldwide, English tends to be used alongside the society or community majority language (Brevik & Rindal 2020; Tsagari & Diakou 2015; Üstünel 2016), and research reveals greater participation and positive attitudes among students when translanguaging is permitted (Ebe 2016; Kleyn 2016; Saxena 2009; Ollerhead 2019; Seltzer

The notion of 'affect' have long been a key concept in the study of fandom, and the term has been used to explicate fandom "affective investments" (Grossberg 1992), "affective play" (Hills 2001) and "affective space" (Lamerichs 2014). The turn, in recent years, to ethnographic study within fandom-studies has led to increasing discussion on researcher/field issues; specifically on self-reflexivity

The building and construction industry is responsible for around 40% of global greenhouse gas emissions, driving the urgent need for new regulations. As such, the life cycle assessment (LCA) methodology has become fundamental for evaluating environmental impacts. Despite the need for digital tools to support environmental performance evaluations, the lack of guidance on developing such tools hinde

In Chonyonyo, a village in north-west Tanzania, the majority of the population have no access to the groundwater beneath them. Every day, women and children walk several hours to a hole shared with animals, to collect contaminated drinking water for their families’ domestic needs. This report shows that the groundwater resources in the area are sufficient to supply the people of Chonyonyo with fre

Since the middle of 1990s and up to today, Sweden and the Swedish justice system have experienced that young men and women are being killed in the name of honour. It was mainly in connection with the murder of Pela and Fadime that the concept of honour killings was rooted in the Swedish public consciousness. Honour killings are crimes whose motive is to re-establish a family’s lost honour, after a

This study looks at how Riksbyggen, one of the biggest residential developers in Sweden, believes that social sustainability is created with architectural aspects within a dwelling. Theory and earlier research within the field of social sustainability and architecture is used to evaluate Riksbyggen’s beliefs. A qualitative content analysis is made to examine the chosen texts from Riksbyggen’s web
