Objective: The COVID-19 pandemic poses an immense need for accurate, sensitive and high-throughput clinical tests, and serological assays are needed for both overarching epidemiological studies and evaluating vaccines. Here, we present the development and validation of a high-throughput multiplex bead-based serological assay. Methods: More than 100 representations of SARS-CoV-2 proteins were inclu

The International Working Group on the Diabetic Foot (IWGDF) has published evidence-based guidelines on the prevention and management of diabetic foot disease since 1999. In conjunction with advice from internal and external reviewers and expert consultants in the field, this update is based on a systematic review of the literature centred on the following: the Population (P), Intervention (I), Co

Introduction: Radiographers routinely undertake many initiatives to balance image quality with radiation dose (optimisation). For optimisation studies to be successful image quality needs to be carefully evaluated. Purpose was to 1) discuss the strengths and limitations of a Visual Grading Analysis (VGA) method for image quality evaluation and 2) to outline the method from a radiographer's perspec

We have made a systematic combined quantum mechanical and molecular mechanical (QM/MM) investigation of possible structures of the N2 bound state of nitrogenase. We assume that N2 is immediately protonated to a N2H2 state, thereby avoiding the problem of determining the position of the protons in the cluster. We have systematically studied both end-on and side-on structures, as well as both HNNH a

Objective To subgroup chronic pain patients using psychometric data and regress the variables most responsible for subgroup discrimination. Design Cross-sectional, registry-based study. Setting and subjects Chronic pain patients assessed at a multidisciplinary pain centre between 2008 and 2015. Methods Data from the Swedish quality registry for pain rehabilitation (SQRP) were retrieved and analyse

Purpose: There is an an increasing awareness of the importance of health and lifestyle for stroke diseases like spontaneous subarachnoid hemorrhage (SAH). However, the importance of pre-existing medical conditions for clinical course and mortality after SAH has not been studied. The aim of the present study was to identify pre-existing conditions contributing to mortality after SAH. Methods: Data

We train and compare the performance of two machine learning methods, a multi-variate regression network and a ResNet-50-based neural network, to learn and forecast plant biomass as well as the relative growth rate from a short sequence of temporal images from plants in aeroponic cultivation. The training dataset consists of images of 57 plants taken from two different angles every hour during a 5

The extensive use of antibiotics over the last decades is responsible for the emergence of multidrug-resistant (MDR) microorganisms that are challenging health care systems worldwide. The use of alternative antimicrobial materials could mitigate the selection of new MDR strains by reducing antibiotic overuse. This paper describes the design of enzyme-based antimicrobial cellulose beads contai

In comparison with instrumental sight reading of musical notation, sight singing is typically characterized by the presence of lyrics. The purpose of this study was to explore how skilled sight singers divide their visual attention between written music and lyrics and how their eye-movement behavior is influenced by musical stimulus complexity. Fourteen competent musicians performed 10 newly compo

Changing demographics in most of western society bring a range of new demands in the field of food and more specifically in food packaging. The need for convenience is one of the biggest drivers behind many innovations over the past decades. Current trends involve psychological convenience on environmental aspects, as well as ease of opening. Easy to open packaging is desirable because consumers w

The data visualization softwares Qlikview and Qlik Sense are based on an associative data model, and this thesis analyzes different tools and methods for solving 0-1 integer programs as well as examines their applicability to the computational engine behind these softwares. The first parts are dedicated to a theoretical background on mathematical optimization, linear programming and Qlik’s impleme

TMP, kort för Trimetylolpropan, är en kemisk komponent som används som byggsten för alkydproduktion inom färgindustri samt som komponent i syntetiska smörjmedel. Perstorp har under drygt 50 år producerat TMP för vidare försäljning till andra kemiska industrier. Under denna period har produktionskapaciteten ökat många gånger om. Denna produktivitetsökning har kommit som följd av ett ”trial and erroThe production of TMP (Trimethylolpropane) is important for many applications, and is used as alkyds in paint and lubricants among others. The reactions producing TMP consist of two major reaction chains, Aldol condensation and Cannizzaro reaction. To get a deeper understanding and improve the running conditions the kinetic expressions for the reactions were examined. The aim of this paper was to
