A model of an industrial through-dryer for production of tissue paper was developed. The model can be used to predict the performance of a dryer section of an industrial through-drying machine consisting of one or more through-drying rolls separated by free draw sections. Roll diameters, wrap angles, machine speed, basis weight, initial paper moisture ratio, operating pressure differentials, dryin
The present study examined the influences of the muscle contraction (MCP) and relaxation (MRP) phases, as well as systole and diastole, on the blood velocity profile and flow in the conduit artery at different dynamic muscle contraction forces. Eight healthy volunteers performed one-legged dynamic knee-extensor exercise at work rates of 5, 10, 20, 30, and 40 W at 60 contractions per minute. The ti
One of the outstanding challenges presented by liquid water is to understand how molecules can move on a picosecond time scale despite being incorporated in a three-dimensional network of relatively strong H-bonds. This challenge is exacerbated in the supercooled state, where the dramatic slowing down of structural dynamics is reminiscent of the, equally poorly understood, generic behavior of liqu
Background: Behavioral testing provides an essential approach in further developing our understanding of brain structure and function. The aim of our study was to outline a more expanded approach to cognition- and anxiety-related behavior in the rabbit. Methods: Twenty-one 70-day old rabbits (13 female, 8 male) were exposed to open field test, dark-light box test and object recognition testing wit
The environmental effects of brine discharge in the Arabian/Persian Gulf have been assessed. The Arabic Gulf is a wide and shallow system having a horizontal shear dominance. The management choice of mixing brine with wastewater to reduce the salt content in the discharge has also been considered. Approximately 90% of the area around the Arabian Gulf has been compared with the world data for desal
BACKGROUND: Hypoxia and increased glycolytic activity of tumors are associated with poor prognosis. The purpose of this study was to investigate differences in radiotherapy (RT) dose painting based on the uptake of 2-deoxy-2-[(18) F]-fluorodeoxyglucose (FDG) and the proposed hypoxia tracer, copper(II)diacetyl-bis(N(4))-methylsemithiocarbazone (Cu-ATSM) using spontaneous clinical canine tumor model
AimImpaired vibrotactile sense, mirroring diabetic peripheral neuropathy, is present among children and adolescents with type 1 diabetes. This study aims to re-examine the vibrotactile sense of paediatric type 1 diabetes subjects in order to evaluate any alterations in the vibrotactile sense over time.MethodsA VibroSense Meter I device was used to determine the vibrotactile perception thresholds (
Popular Abstract in Swedish Det blir allt vanligare att man ersätter förlorade och skadade kroppsdelar med ett biomaterial (vanligtvis ett metall eller polymer implantat). Exempel på vanliga användningsområden är; suturer, kärl, hjärtklaffar, pacemakers, katetrar, ledproteser, fixationsskruvar för skelett och konstgjorda tänder samt kapslar för långsam frisättning av medicin. Trots det rutinmässigThe biological response to different implanted biomaterials vary. The relative importance of factors in the material and host for this variation are at present incompletely known. The variation in the cellular response to specific proteins and the rapid adsorption of proteins to surfaces exposed to biological environments has created the hypothesis that the cellular interactions with biomaterials
Popular Abstract in Swedish Eld har fascinerat människan i alla tider. Att sitta och värma sig vid en lägereld, sjunga sånger eller bara titta på hur elden rör sig är något de flesta har upplevt. Hur många har egentligen funderat på var värmen kommer ifrån, hur den gula färgen uppstår eller vad eld egentligen består av? Några av frågorna finns det nu svar på, men fortfarande finns det mycket att uThe work presented in this thesis covers how laser-induced fluorescence (LIF) and photofragmentation laser-induced fluorescence (PF-LIF) can be used to determine quantitative species concentrations in different combustion environments. To attain species concentrations with LIF it is of vital importance to investigate the influence of collisional quenching on the fluorescence signal strength, which
BACKGROUND: Data regarding high-sensitivity troponin concentrations in patients presenting to the emergency department with symptoms suggestive of myocardial infarction may be useful in determining the probability of myocardial infarction and subsequent 30-day outcomes. METHODS: In 15 international cohorts of patients presenting to the emergency department with symptoms suggestive of myocardial in
AimsThe aim is to investigate associations between attendance in religious service during the past year and all-cause, cardiovascular (CVD), cancer and other cause mortality.Study designProspective cohort study.MethodsA public health survey with three reminders was sent to a stratified random sample of the adult 18–80 population in southernmost Sweden in 2008. The response rate was 54.1%, and 24,8
Aim To explore the temporal impact of mild COVID-19 on need for primary and specialist health care services. Methods In all adults (≥20 years) tested for SARS-CoV-2 in Norway March 1st 2020 to February 1st 2021 (N = 1 401 922), we contrasted the monthly all-cause health care use before and up to 6 months after the test (% relative difference), for patients with a positive test for SARSCoV-2 (non-h
Background: It is known that chronic pain makes it difficult to lose weight, but it is unknown whether obese patients (body mass index ≥30 kg/m2) who experience significant pain relief after interdisciplinary multimodal pain rehabilitation (IMMPR) lose weight. Objective: This study investigated whether obese patients with chronic pain lost weight after completing IMMPR in specialist pain units. Th
Monitoring constitutes a cornerstone, both for efficient control of optimized industrial processes and for obtaining knowledge about non-controlled, natural phenomena. This thesis is all about monitoring, or measurements. In this case the primary information is gathered with light, and in a non-intrusive, and usually a stand-off or remote way. The applications of optical monitoring in this work
Purpose of the studyIn this paper, we discuss the unexploited possibilities of user-orientation to promote sustainable governance and management of value co-creation in innovation projects within welfare service ecosystem. The paper’s theoretical framework takes the outset in public service logic (PSL) and its user-oriented perspective. As such, we test the thesis that service-innovation seriously
Background: Different tau biomarkers become abnormal at different stages of Alzheimer’s disease (AD), with CSF p-tau typically being elevated at subthreshold levels of tau-PET binding. To capitalize on the temporal order of tau biomarker-abnormality and capture the earliest changes of tau accumulation, we selected a group of amyloid-β-positive (A+) individuals with elevated CSF p-tau levels but ne
Background: Postoperative nausea and vomiting (PONV) is common after general anaesthesia, and corticosteroids are used in many protocols for enhanced recovery after surgery (ERAS). However, surgical techniques are developing, and ERAS protocols need to be reevaluated from time to time. Patients and method: In this study, we compared the effects of oral vs. parenteral corticosteroid administration
Large-scale construction work often requires people to work longer daily hours and more than the ordinary five days in a row. In order to minimize transportation times and optimize the use of personnel, workers are sometimes asked to live in temporary building-site camps in the proximity of the work site. However, little is known about the biological and psychological effects of this experience. T
