Background: Lignosulfonates are significant wood chemicals with a $700 million market, produced by sulfite pulping of wood. During the pulping process, spent sulfite liquor (SSL) is generated, which in addition to lignosulfonates contains hemicellulose-derived sugars—in case of hardwoods primarily the pentose sugar xylose. The pentoses are currently underutilized. If they could be converted into v

Popular Abstract in Swedish Digital bildteknik dominerar snart all bildhantering inom alla delar av samhället. Målsättningen med denna avhandling var att utveckla en undersökningsmetod för mätning av knäleden i belastat läge med hjälp av digital bildplatteteknik. Vad är bildplatteteknik? Traditionellt har röntgenbilder framställts med hjälp av fotografisk film. De framkallade bilderna har sedan The overall aim of this study was to develop and evaluate a measurement system for computed radiography (CR) and Picture Archiving and Communication Systems (PACS), permitting measurements of long distances and angles in and between related images. The developed measurement system, which was based on the QUESTOR Precision Radiography (QPR) system, was applied to the weight-bearing knee with specia

Some leading science programs undertaken with Very Large Telescopes and challenges driving the progress of the Extremely Large Telescopes are discussed together with the corresponding requirements. They concern expolanets, Earth-like planets, habitable zones, formation of stars and galaxies, first stars and cosmology. A description is attempted

Breast cancer is the most common cancer in women worldwide, identification of new biomarkers for early diagnosis and detection will improve the clinical outcome of breast cancer patients. In the present study, we determined serum levels of vitronectin (VN) in 93 breast cancer patients, 30 benign breast lesions, 9 precancerous lesions, and 30 healthy individuals by enzyme-linked immunosorbent assay

In this work a compact fluorosensor has been built for point-monitoring and imaging applications. The instrument has been applied in fluorescence studies on green vegetation and on malignant tissue. The instrument is based on a violet diode laser, an integrated spectrometer and optical fibers for light delivery and collection of the fluorescence signal. This combination makes the system very compa

The European Resuscitation Council (ERC) and the European Society of Intensive Care Medicine (ESICM) have collaborated to produce these post-resuscitation care guidelines for adults, which are based on the 2020 International Consensus on Cardiopulmonary Resuscitation Science with Treatment Recommendations. The topics covered include the post-cardiac arrest syndrome, diagnosis of cause of cardiac a

Since most models used to study neuronal dysfunction display disadvantages and ethical concerns, a fast and reproducible in vitro model to study mitochondria-related neurodegeneration is required. Here, we optimized and characterized a 3-day retinoic acid-based protocol to differentiate the SH-SY5Y cell line into a neuronal-like phenotype and investigated alterations in mitochondrial physiology an

For patients with gastroenteropancreatic neuroendocrine tumours (GEP-NET), health-related quality of life (HRQoL) is important. Meanwhile, whether tumour volume is associated with HRQoL is unknown. Hence, the aim of this study was to assess if total somatostatin receptor expressing tumour volume is correlated with HRQoL in patients with metastatic GEP-NET. Some 71 patients were included in the stu

Climate change and human activities threaten the availability and quality of fresh water resources globally, especially in less developed countries, where poverty and natural disaster risks are present. Despite important research efforts, gaps still exist regarding the understanding of the spatial-temporal variations of water quality and the movement of organic matter within tropical mountain lake

Timely detection and surveillance of disease community spread is a potent tool for implementing effective public health interventions. This study investigates the National Telehealth Service (1177 helpline) across 18 regions in Sweden in 2020 to identify early signals of community transmission of COVID-19 at the beginning of the pandemic. Focusing on calls related to key COVID-19 symptoms (cough,

Background: Neuroimaging with magnetic resonance imaging (MRI) may assist clinicians in evaluating brain injury and optimising care in comatose adults resuscitated after out-of-hospital cardiac arrest (OHCA). However, contemporary international data on its use are lacking. Aim: The primary aim was to compare the patient characteristics, early postresuscitation care, and neurological outcomes of pa

Background:Preparing for the end of life is believed to help mitigate emotional suffering for both patients and their caregivers. However, empirical evidence on the emotional benefits of feeling prepared for death remains limited.Aim:This study uses data from the international iLIVE project to examine how perceived end-of-life preparedness is associated with emotional suffering among patients and

Introduction: Using a sum score based on a three-graded response scale for the activities of daily living staircase has previously been found to increase the statistical power compared to dichotomized responses when assessing longitudinal changes in activities of daily living. We aimed to investigate if the statistical power could be further increased by using a four-graded scale. Methods: We used

Automation: Optimering av din tid Tänk dig att du har fått en deadline på ditt nya projekt. Ditt arbete för projektet beror helt på din praktiska noggrannhet och tidsoptimering, samtidigt så ska du lämna in massvis med pappersarbete. Du har en tuff tid framför dig ifall du ska klara detta på egen hand inom tidsramen. Här kommer automatisering in i bilden. Det noggranna och tidskrävande arbetet soAutomated information flow is an important way of optimizing the time used for analyzing processes. Other added benefits are that in a well-made automated system, the probability of human error diminishes because less liability is put on the person to manually transport and utilize the data. This notion of automation can be applied to the field of chromatography. This thesis investigates the poss

The thesis starts with a description of the background to the change of the rules on deduction of VAT on mixed use immovable property through the insertion of Article 168a in the RVD. The reason according to the Amendment is to promote equity and to prevent unjustified cash-flow advantages granted to taxable persons who use acquire immovable property, deduct full input VAT and then pay it back o
