I dagsläget ligger byggbranschen efter många andra industrier när det kommer till effektivisering av metoder. Branschen är väldigt beroende av materialleveranser och att dessa sker utan störreproblematik. Det är viktigt att arbeta för att material anländer i rätt tid, rätt mängd och på rätt plats för att undvika förseningar och onödiga kostnader. Med ett stort intresse för effektivisering av byggIn the current situation the building industry is behind other industries when it comes to making methods more effective. The industry relies on deliveries of material and that these happen without trouble. It’s important to work towards material being delivered at the correct time, correct quantity, and the correct place to avoid delays and unnecessary costs. With a great interest in making the

Nanofiber-reinforced hydrogels have recently gained attention in biomedical engineering. Such three-dimensional scaffolds show the mechanical strength and toughness of fibers while benefiting from the cooling and absorbing properties of hydrogels as well as a large pore size, potentially aiding cell migration. While many of such systems are prepared by complicated processes where fibers are produc

Downy mildew disease, caused by the biotrophic oomycete Peronospora variabilis, is the largest threat to the cultivation of quinoa (Chenopodium quinoa Willd.) in the Andean highlands, and occurs worldwide. However, so far, no molecular study of the quinoa–Peronospora interaction has been reported. Here, we developed tools to study downy mildew disease in quinoa at the gene expression level. P. var

This thesis explores the lived experiences of Yemeni individuals with marginalization in context of the contemporary civil war. Experiences on the margin are approached from a multifaceted framework which allows for a contextual understanding of how Yemeni bodies face social, political and economic exclusion. In-depth semi-structured interviews with seven Yemeni individuals provide this study with

The term hybrid immunity is used to denote the immunological status of vaccinated individuals with a history of natural infection. Reports of new SARS-CoV-2 variants of concern motivate continuous rethought and renewal of COVID-19 vaccination programs. We used a naturalistic case-control study design to compare the effectiveness of the BNT162b2 mRNA vaccine to hybrid immunity 180 days post-vaccina

Several studies have shown decreased cerebral blood flow (CBF) in Alzheimer's disease (AD). However, the role of hypoperfusion in the disease pathogenesis remains unclear. Combining arterial spin labeling MRI, PET, and CSF biomarkers, we investigated the associations between gray matter (GM)-CBF and the key mechanisms in AD including amyloid-β (Aβ) and tau pathology, synaptic and axonal degenerati

Background: Access to emergency and essential surgical care is still unmet and accessibility is disproportionately inequitable in Ethiopia and other low-and middle-income countries. The aim of this study was to assess surgical care access in terms of capability, capacity, and timeliness of care in different levels of health care in Ethiopia. Methods: A cross-sectional study with retrospective data

In this study, we modeled the aerosol particle formation along air mass trajectories arriving at the remote Arctic research stations Gruvebadet (67 m a.s.l.) and Zeppelin (474 m a.s.l.), Ny-Ålesund, during May 2018. The aim of this study was to improve our understanding of processes governing secondary aerosol formation in remote Arctic marine environments. We run the Lagrangian chemistry transpor

Cell-free hemoglobin (CFH), a pro-oxidant and cytotoxic compound that is released in hemolysis, has been associated with nephrotoxicity. Lung transplantation (LuTx) is a clinical condition with a high incidence of acute kidney injury (AKI). In this study, we investigated the plasma levels of CFH and haptoglobin, a CFH-binding serum protein, in prospectively enrolled LuTx patients (n = 20) with and

Purpose: To describe performed moral case deliberations and present a nationwide study of difficult situations and moral questions raised by healthcare professionals during moral case deliberations in Swedish childhood cancer care. Methods: Written reports (n = 72) about difficult situations and moral questions were completed by healthcare professionals, trained as facilitators, who implemented mo

Background: Environmental exposures to industrial chemicals, including perfluoroalkyl substances (PFAS), may play a role in bone development and future risk of osteoporosis. However, as prospective evidence is limited, the role of developmental PFAS exposures in bone density changes in childhood is unclear. The objective of this study was to estimate associations between serum-PFAS concentrations

We present a novel method, to our knowledge, to control the shape of the spectra using 2-beam hybrid femtosecond (fs)/nanosecond (ns) coherent anti-Stokes Raman scattering (RCARS). The method is demonstrated experimentally and theoretically by utilizing a species-selective excitation approach via a field-free molecular alignment as an illustrative example. Two non-resonant fs laser pulses with pro

States in the Global South are facing a double challenge of achieving socio-economic development while adapting to climate change impacts. This study maps to what extent Small Island Developing States (SIDS) manage to meet the Sustainable Development Goals (SDGs). The SIDS are at the front line of climate change and while they share numerous challenges, the SIDS are also a heterogeneous group cont

The Keccak sponge function family, designed by Bertoni et al. in 2007, was selected by the U.S. National Institute of Standards and Technology (NIST) in 2012 as the next generation of Secure Hash Algorithm (SHA-3). Due to its theoretical and practical importance, cryptanalysis of SHA-3 has attracted a lot of attention. Currently, the most powerful collision attack on SHA-3 is Jian Guo et al.’s lin

In search for measures to reduce greenhouse gas emissions from transport, insights into the characteristics of all sorts of trips and specifically trips by car are needed. This paper focuses on everyday leisure trips for social and recreational purposes. Travel behaviour for these purposes is analysed considering individual and household factors as well as properties of the trip, based on Swedish

This article investigates a series of attempts to imbue natural history with humanistic values and align its epistemological goals with those of classical studies in Sweden during the first half of the nineteenth century. By tracing the claims made by a group of twenty-one natural scientists, physicians, and state officials as well as others who took up the cause in response to a government propos

Large-scale high-quality van der Waals CoPS3single crystals are synthesized using a chemical vapor transport (CVT) method. The crystallographic structure and electronic properties of this layered material are systematically studied using different spectroscopic methods (XPS, NEXAFS, and resonant photoelectron spectroscopy) accompanied by density functional theory (DFT) calculations. All experiment

This paper considers the problem of jointly designing the transmit waveforms and weights for a frequency diverse array (FDA) in a spectrally congested environment in which unintentional spectral interferences exist. Exploiting the properties of the interference signal induced by the processing of the multi-channel mixing and low-pass filtering FDA receiver, the interference covariance matrix struc

The literature gives limited data or guidance on how to select or combine biomarkers and magnetic resonance imaging (MRI) for the early detection of prostate cancer. We strongly recommend prospective studies large enough to address questions such as the properties of biomarkers in cases with high versus low Prostate Imaging-Reporting and Data System scores or the correlation between biomarkers and
