Sweden passed legislation to achieve a target of net zero greenhouse gas emissions by the end of 2045. The Energy Performance of Building Directive further obliged European countries to ensure zero-energy building codes and improve the quality of indoor environments when buildings are renovated, as approximately 40% of total greenhouse gas emissions in Sweden are produced while heating buildings.
This study examines the views of stakeholders involved in house renovations regarding the one-stop-shop business concept innovation, and assesses their level of preparedness to adopt such a concept in order to enter the promising market of detached house renovations. The investigation is based on 25 interviews with construction SMEs owners, real estate agents and loan consultants, and on a concept
Buildings are responsible for 40% of energy consumption and 36% of CO2 emissions in the EU. Sweden andDenmark are cold climatic countries with strong demand for space heating and hot water in the residential sector. Large section of the detached houses in these countries are built more than 30 years ago and need refurbishment. Despite of huge energy saving potentials with deep renovation of these
A novel energy management (EM) approach is introduced, integrating core elements of collective intelligence (CI) and reinforcement learning (RL) and called CIRLEM. It operates by distributing a flexibility signal from the energy supplier to agents within the grid, prompting their responsive actions. The flexibility signal reflects upon the collective behaviour of the agents in the grid and agents
A new concept has been developed for characterizing the real-time evolution of the three-dimensional pore and lamella microstructure of bread during baking using synchrotron X-ray microtomography (SRµCT). A commercial, combined microwave-convective oven was modified and installed at the TOMCAT synchrotron tomography beamline at the Swiss Light Source (SLS), to capture the 3D dough-to-bread structu
This thesis focuses on the removal of organic micropollutants and transformation products using ozone and activated carbon treatment processes. A combination of 14C-labeled and non-radiolabeled organic micropollutants was used to study aspects of micropollutant removal from novel perspectives. 14C-labeled ozone transformation products (OTPs) were generated by ozonation of 14C-labeled micropollutan
The Eastern Orthodox Churches in post-communist Eastern Europe are embroiled in long-running conflicts over ownership of territory, saints, sites, nations, and history. These often violent conflicts reflect political and national rivalries, most explicitly in former Yugoslavia and Ukraine. They are often understood as simplified ethnic-national tensions with religious overtones, but, as this book
Accurate estimate of stem volume is crucial to forest management. In this study, we developed allometric equations of stem volume of Acacia auriculiformis after destructive harvesting of 48 individual trees. We also took digital photographs of each sample tree just before destructive harvesting from the felling operations of Bangladesh Forest Department in short rotation (10-15 years) plantations.
High-grade gastroenteropancreatic (HG-GEP) neuroendocrine neoplasms (NENs) are highly aggressive cancers. The molecular etiology of these tumors remains unclear, and the prevalence of pathogenic germline variants in patients with HG-GEP NENs is unknown. We assessed sequencing data of 360 cancer genes in normal tissue from 240 patients with HG-GEP NENs; 198 patients with neuroendocrine carcinomas (
Online wall temperatures were measured with fiber-coupled phosphor thermometry in a full-scale gas turbine combustor. The combustor was operated with natural gas and up to 100 vol% hydrogen at engine-relevant conditions. Two phosphors were tested for this application, namely YAG:Dy and YAG:Tm;Li. Although YAG:Tm;Li seemed to be the most promising phosphor for this application, it turned out to be
Construction and demolition workers are exposed to high levels of particulate matter (PM) from building materials throughout their working life. Although nano-enabled building materials (NEBMs) may improve the performance and functionality of buildings, concerns are being raised regarding health risks from occupational exposure to PM from NEBMs. In this work, an experimental set-up for integrated
In this work, we demonstrate the capability of the hot-wall metalorganic chemical vapor deposition to deliver high-quality n-AlxGa1−xN (x = 0 – 0.12, [Si] = 1×1017 cm−3) epitaxial layers on 4H-SiC(0001). All layers are crack-free, with a very small root mean square roughness (0.13 – 0.25 nm), homogeneous distribution of Al over film thickness and a very low unintentional incorporation of oxygen at
IMPORTANCE: The incidence of diabetes in childhood has increased during the COVID-19 pandemic. Elucidating whether SARS-CoV-2 infection is associated with islet autoimmunity, which precedes type 1 diabetes onset, is relevant to disease etiology and future childhood diabetes trends.OBJECTIVE: To determine whether there is a temporal relationship between SARS-CoV-2 infection and the development of i
The objective of this study is to present a text-critical edition of the medieval treatise Maqāla fī l-Faṣd, ‘On Phlebotomy’, attributed to Abū Bakr Muḥammad ibn Zakariyyāʾ al-Rāzī (865-925), a prominent physician and scholar known especially for his expertise in medicine. His contributions as a distinguished medical author and devoted clinician earned him recognition in both Arabic and Latin medi
