Direct ground cooling is a method for cooling buildings whereby free cooling is provided by circulating water through borehole heat exchangers (BHEs). Since no refrigeration cooling is involved, supply water temperature to the building's cooling system is dependent mainly on BHE sizing. This study investigates the sizing of BHEs for direct ground cooling systems, with a particular focus on the inf

Direct ground cooling systems (DGCS) can provide comfort cooling to buildings without the use of any refrigeration-based cooling methods. DGCS is an emerging technology, commonly used for new office buildings in cold climates. This study aims to evaluate the energy-saving possibilities of a DGCS compared to a conventional chiller system for an existing office building. A typical Swedish office bui

This article offers the first empirical and cross‐national analysis of citizens’ views about the democratic importance of the public sphere. We first identify three normative functions that public spheres are expected to perform in representative democracies: they provide voice to alternative perspectives, they empower citizens to criticise political authorities and they disseminate information on

In this thesis, I attempted to achieve a better understanding of the nature of X-linked polymorphic loci using a female-limited X chromosome (FLX) experimental evolution in Drosophila melanogaster. I expected that expressing the evolved X chromosome will result in an increase in female fitness and a decrease in male fitness. I first investigated the effect of an experimentally evolved female-limit

Transboundary research collaborations (TRCs) are critical in supporting evidence-based actions to address complex global issues. However, there is still a lack of empirics, which would detail how TRCs are organised, how activities are facilitated, and how actors interplay. In this article, we address this gap through the evaluation of a North-South TRC against the 11 principles for TRCs by the Com

PURPOSE: Tamoxifen prevents breast cancer in high-risk women and reduces mortality in the adjuvant setting. Mammographic density change is a proxy for tamoxifen therapy response. We tested whether lower doses of tamoxifen were noninferior to reduce mammographic density and associated with fewer symptoms.PATIENTS AND METHODS: Women, 40-74 years of age, participating in the Swedish mammography scree

Most waste textiles are currently incinerated or landfilled, which is becoming an increasing environmental problem due to the ever-increasing consumption of textiles in the world. New recycling processes are required to address this problem and, although textile-to-textile recycling would be preferable, many researchers have suggested implementing processes based on the depolymerization of the tex

We present an in-depth investigation of laser-induced grating spectroscopy (LIGS) for temperature measurements in practical applications using a narrow-band dye laser with 760 nm wavelength and a pulse duration of 8 ns as the source for the pump beams creating the laser-induced grating. The pump laser wavelength was set to be either resonant with the (Formula presented.) transition from the (Formu

Recently, a 1.83 Å crystallographic structure of nitrogenase was suggested to show N2-derived ligands at three sites in the catalytic FeMo cluster, replacing the three μ2 bridging sulfide ligands (two in one subunit and the third in the other subunit) (Kang et al. in Science 368: 1381–1385, 2020). Naturally, such a structure is sensational, having strong bearings on the reaction mechanism of the e

Svenska Akademiens ordbok (SAOB) är en historisk och samtidsspråklig ordbok som beskriver det svenska språket från 1521 fram till nutid. Projektet har pågått sedan slutet av 1800-talet och närmar sig nu sin fullbordan. När en komplett ordbok från A–Ö är färdig börjar det omfattande arbetet med att uppdatera och revidera ordboksinnehållet. Därmed finns det för första gången på 125 år möjlighet att

There is an urgent need for radical transformations of unsustainable socio-technical systems, such as food, mobility, and housing. These transformations will not take place without new policies and research. In order to achieve these transitions, learning must be a central feature based on thorough evaluations of the actions taken. Evaluations have been conducted and studied for decades, but tradi

Understanding energy transport in metal halide perovskites is essential to effectively guide further optimization of materials and device designs. However, difficulties to disentangle charge carrier diffusion, photon recycling, and photon transport have led to contradicting reports and uncertainty regarding which mechanism dominates. In this study, monocrystalline CsPbBr3 nanowires serve as 1D mod

Precipitation over the Tibetan Plateau (TP) has major societal impacts in South and East Asia, but its spatiotemporal variations are not well understood, mainly because of the sparsely distributed in situ observation sites. With the help of the Global Precipitation Measurement satellite product IMERG and the ERA5 dataset, distinct precipitation seasonality features over the TP were objectively cla

The reaction kinetics of hydrogen-abstraction reactions from methoxymethanol (CH3OCH2OH) by hydrogen (Ḣ) atom, hydroxyl (ȮH), hydroperoxyl (HȮ2), methyl (ĊH3) and methoxyl (CH3Ȯ) radicals, and decomposition of the related hydroxyl-methoxyl-methyl (CH3OĊHOH), hydroxymethoxyl-methyl (ĊH2OCH2OH) and methoxyl-methoxy (CH3OCH2Ȯ) radicals, have been investigated in this study through high-level ab initi

Purpose: The purpose of this study is to investigate the effects of film holes’ arrangements and jet Reynolds number on flow structure and heat transfer characteristics of jet impingement conjugated with film cooling in a semicylinder double wall channel. Design/methodology/approach: Numerical simulations are used in this research. Streamlines on different sections, skin-friction lines, velocity,

Background: Ice hockey players often undergo arthroscopic treatment for femoroacetabular impingement syndrome (FAIS); however, only a few studies have reported postoperative patient-reported outcomes. It has been debated whether player position is related to FAIS. Purpose: To evaluate the change in patient-reported outcome measures (PROMs) in high-level ice hockey players from presurgery to 2 year
