Hydraulic balancing is key to ensure proper operation of the heating system. When the heating system is not hydraulically balanced, heat is unevenly distributed across dwellings resulting in a wide temperature spread, overheating, and consequently, wastage of energy. In this paper, we study to which extent hydraulic imbalance affects the thermal energy demand of buildings. Furthermore, key variabl

Background: There is currently a steady increase in the use of wood-based fuels for heat and power production in Sweden. A major proportion of these fuels could serve as feedstock for ethanol production. In this study various options for the utilization of the solid residue formed during ethanol production from spruce, such as the production of pellets, electricity and heat for district heating, w

Today the self-proclaimed caliphate IS is one of the most feared and well known phenomenon of its time. Major military operations against the group have been initiated with the United States in the forefront but at the same time expression of opinions argue that IS has to be addressed in other ways than just military. The ideas of IS have been widely spread, this proliferation can be attributed to

There is great potential to apply energy recovery from municipal wastewater treatment plants (WWTP) to achieve better energy efficiency and greenhouse gas emissions abatement. However, in most of the wastewater treatment plants that produce biogas through sludge digestion, there is no thermal energy recovery or electricity generation, and the biogas is flared and wasted, particularly in developing

This article analyses the energy transition of the Swedish iron and steel industry (1800–1939), a leading actor in the European iron and steel market during the 19th and 20th centuries.This industry is an interesting case to analyse from the perspective of energy transition and the composition and change of capital stock (classified by energy technology). in-depth review of the this topic will ena

Institutionen för processteknik och tillämpad biovetenskap bildades i januari 2024 efter en sammanslagning av Institutionen för kemiteknik och Institutionen för livsmedelsteknik. Välkommen till en institution som tar sig an ett brett spektrum av forskningsfrågor, ger utbildningar som är efterfrågade av arbetsmarknaden och samarbetar i en internationell miljö. Många av våra forskare och lärare arbWe were formed in January 2024 after a merger of the Department of Chemical Engineering and the Department of Food Technology, Engineering and Nutrition. Welcome to a department that addresses a wide range of research issues, provides education that is in demand by the labour market and collaborates in an international environment. Many of our researchers and teachers work at the global forefront

We define a ray, show how to use ray intervals, and demonstrate how to specify a ray using DirectX Raytracing (DXR).

A few large fires in Lithium-ion battery systems are known to have been caused by leaking coolant, and experience from fire testing indicate that coolant can be the origin of violent fires triggered before the onset of thermal runaway in the battery. It is here hypothesized that the common coolants water and ethylene glycol can form flammable gases via electrolysis in the electrical environment fo

The sharing economy has many faces, and it has taken our societies by storm. For many people, it has quickly become a norm to book accommodation via AirBnB, or to think sharing instead of owning when it comes to products of their everyday lives. The tourism industry has seen many adaptions towards a sharing economy, one of them being a new way of conducting guided tours. Based on an innovation in

Purpose – The purpose of this paper is to explore, illustrate, and conceptualize how sustainability service is performed and the role it plays in the promotion of sustainable consumption. Design/methodology/approach – Theoretically, this paper takes a practice theory approach, conceptualizing the provision of sustainability service as a set of complex, socio-material, and performative practices. M

People struggle to name odors [1–4]. This has been attributed to a diminution of olfaction in trade-off to vision [5–10]. This presumption has been challenged recently by data from the hunter-gatherer Jahai who, unlike English speakers, find odors as easy to name as colors [4]. Is the superior olfactory performance among the Jahai because of their ecology (tropical rainforest), their language fami

The strongest constraint on Vtb presently comes from the 3 × 3 unitarity of the CKM matrix, which fixes Vtb to be very close to one. If unitarity is relaxed, current information from top production at Tevatron still leaves open the possibility that Vtb is sizably smaller than one. In minimal extensions of the standard model with extra heavy quarks, the unitarity constraints are much weaker, and th

This paper addresses the life, work, representations, and official policies surrounding so-called representative bearers (daibiao chuancheng renwu) of tradition. The paper provides an overview of this policy and the selection process at both the local, national and global level. The paper focuses on the field of ancestral ceremonies and aim to illustrate the artificial and arbitrary dichotomy that
