In recent years, there has been an increasingly larger fraction of intermittent energy sources. In the northern parts of Europe, the main source of intermittent power is wind power. This source of power is low inertia, inconsistent and will always fluctuate with different magnitudes, leaving a need for balancing. One source of balancing is to have the widespread non-zero inertia combined heat and

We assessed the serum concentration of gamma-carboxylated osteocalcin (OC), total OC, and full-length OC in a clinical setting of 37 patients on continuous warfarin treatment (international normalized ratio 2.0-3.8). A comparison was done with the results from 30 untreated age-matched controls. Four monoclonal antibodies, previously generated and characterized as to their ability to recognize diff

Electrical remodelling is believed to influence the outcome following cardioversion of patients with persistent atrial fibrillation (AF). However, the results in clinical studies are conflicting. We assessed the hypothesis that non-invasively obtained atrial fibrillatory organization can be used as a predictor of sinus rhythm (SR) maintenance. METHODS AND RESULTS: Fifty-four patients (37 men, age

The Internet offers a plethora of venues for autobiographical self-representation: webcams, personal websites, blogs. There is much research on self-representation online, whereas very little research has focused on the consumption of online self-representation. This article focuses on the act of reading diary blogs. Who are the actual readers of a specific blog and what values do they place on th

Enzymatic hydrolysis is an agro-processing aid that can be utilized in order to improve nutritional quality of protein extracts from many sources. In this study, protein extracts from ungerminated and/or germinated local Egyptian soybean and lupin flours were hydrolyzed using the enzyme papain. The hydrolysis processes were carried out for 2 h and aliquots were withdrawn at different time interval

Twelve palaeogeographical reconstructions illustrate environmental changes at the southwest rim of the Scandinavian Ice Sheet 40-15 kyr BP. Synchronised land, sea and glacier configurations are based on the lithostratigraphy of tills and intertill sediments. Dating is provided by optically stimulated luminescence and calibrated accelerator mass spectrometry radiocarbon. An interstadial sequence ca

Background: Studies on exercise in knee osteoarthritis (OA) have focused on elderly subjects. Subjects in this study were middle-aged with symptomatic and definite radiographic knee osteoarthritis. The aim was to test the effects of a short-term, high-intensity exercise program on self-reported pain, function and quality of life. Methods: Patients aged 36 - 65, with OA grade III (Kellgren & La

Fungal (acetate-in-ergosterol incorporation) and bacterial (leucine/thymidine incorporation) growth resulting from alfalfa (C/N = 15) and barley straw (C/N = 75) addition was studied in soil microcosms for 64 days. Nitrogen amendments were used to compensate for the C/N difference between the substrates. Fungal growth increased to a maximum after 3–7 days, at five to eight times the controls, foll

The aim of this study was to investigate possible changes in quality of life (QoL) in elderly persons diagnosed with cancer (65 years and above), in relation to age, contact with the health-care system, activities of daily living, hope, social network and support. The investigation points were at time of diagnosis (baseline), and again 3 and 6 months after the diagnosis. The study also aimed to in

This paper investigated how different types of automation affect tactical driving behavior, depending on trust in the system. Previous research indicates that drivers wait for automation to act, delegating the monitoring of traffic situations. This would be especially true for those who have more trust in automation. Behavioral and gaze data from 30 participants driving an advanced simulator were

For future usage of services and applications, it would be beneficial to be able to use only one terminal for their communication needs. The intention is also that the terminal should stay connected even if it has to change technology, system and/or operator. This means that a user will need to have a terminal, which can use different types of wireless systems. As well as that the systems have the

MASTER (MAnaging Speeds of Traffic on European Roads) aims to provide recommendations for speed management strategies and policies and to elaborate guidelines for the development of innovative speed management tools. Within the framework of the project, field trials with a car equipped with a speed limiter were carried out in three “regional typical” European countries: Sweden, the Netherlands, an

Oil was extracted from fatty material obtained from Nile perch viscera using the protease Protex 30L. Enrichment of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in the glyceride fraction was carried out by hydrolysis of extracted oils with lipases from Candida rugosa, Thermomyces lanuginosus and Pseudomonas cepacia. The unusual fatty acid distribution of the oil influenced the appare

Diabetes and obesity have long been known to be related. The recently characterized adipocyte hormone resistin (also called FIZZ3/ADSF) has been implicated as a molecular link between impaired glucose tolerance (IGT) and obesity in mice. A search for sequence variants at the human resistin locus identified nine single-nucleotide polymorphisms (SNPs) but no coding variants. An investigation into th

In this thesis, I examine how the COVID-19 pandemic has affected six libraries in the Swedish public library system through interviews with employees at said libraries during the period between March 2020 to March 2021. In the first year of the COVID-19 pandemic, access to digital media, the Internet and assistance from library staff have been limited. Most activities aiming to promote digital li

Kvalitetskontrollsmodell för textilåtervinning 2025 infördes en EU-lag som gjorde det obligatoriskt att sortera textilavfall separat. Här presenteras grunden för en modell som relaterar reaktorparametrar till kvalité på återvunnen textilmassa. Textilindustrin omfattade 2024 knappt 2 biljoner USD. Det är en global industri där textilierna ofta designas i USA, produceras i asiatiska länder och slutTextile recycling is highly needed as great amounts of waste are produced every year and most of it is put into landfill or incinerated. This thesis lays the foundations for a quality control system which may be applied for controlling the recycling of cellulosic textiles in an upcoming pilot plant based on ShareTex’s technology. The quality control system was constructed as a mathematical model r

Välgrundade förutsägelser av olika livsmedels kvalitet och säkerhet är mycket viktiga för att förebygga matsvinn. Ofta görs dessa förutsägelser med hjälp av lagringsstudier där produkten lagras i förhållanden som simulerar produktens väg från producent till dagligvaruhandel. Dessa studier kräver mycket resurser och tid, vilket belyser behovet av accelererade hållbarhetsstudier – som är baserade påAccurate predictions about the quality and safety of food are critical to prevent food waste. Often, food is stored in conditions simulating a product’s way from production to retail, which allows producers to assess quality and safety during the product’s shelf life. These storage trials are costly and time-consuming, meaning that there is incentive to reduce the testing time. Accelerated shelf-l

Populärvetenskaplig beskrivning: Att veta hur olika saker i världen kom till hjälper en att släcka den törstiga sömn-förstörande nyfikenheten. Många har ställt sig frågan: hur skapades universum? Någorlunda hela svar har lagts fram (som till exempel teorin om Big Bang), men det finns mer att upptäcka. På en relativt mindre skala kan man fråga sig hur skapades Vintergatan? Ännu en fråga delvis svaradThe properties of the early Milky Way are quite mysterious and some are completely unknown even today. This study is the first one ever to analyze the mass distribution of Population III bulge stars. Using the fitting code STARFIT, we perform an analysis of 65 bulge metal-poor stars obtained by the EMBLA survey to estimate the IMF (initial mass function) of the very first stars that defined our ga

Biskop Bengt Jonzon i Luleå stift instiftade en tjänst som kyrkoherde för samer på 1950-talet. Författaren beskriver bakgrunden till detta baserat på publikationer av biskop Jonzon, en biografi av hans son Bror Jonzon samt diverse arkivmaterial. Slutsatsen är att tjänsten ger innehavaren bättre möjligheter att utveckla sim språkliga kompetens samt att genom att använda samernas modersmål bättre up
