This is a study on the recovery and recycling of copolymer in aqueous two-phase systems containing random copolymers of ethylene oxide (EO) and propylene oxide (PO). The random copolymers separate from water solution when heated above the lower critical solution temperature (LCST). The primary phase systems were composed of EOPO copolymer and hydroxypropyl or hydroxyethyl starch. After phase separ
Air samples were collected on glass fibre filters in 22 animal houses and 3 hay storage barns and examined for the presence of bacterial endotoxin with the Limulus (LAL) test and the gas chromatography - tandem mass spectrometry (GC-MSMS) technique, based on detection of 3-hydroxy fatty acids (3-OH-FAs) as chemical markers of the endotoxin lipopolysaccharide. The median concentrations of airborne
A method is presented to infer cloud liquid water path (LWP in kg/m2) over the ocean from passive microwave measurements of SSM/I. The algorithm to retrieve LWP is based on simulated satellite observations. They are calculated with a radiative transfer model applied to about 3000 radiosonde ascents over the Atlantic Ocean. Since radiosonde observations do not contain direct information about cloud
The presence of graphite particles in gray cast iron commonly implies a good machinability, especially if compared to common steels. However, increasing industrial demands have resulted in a new interest for high-speed machining of these materials with higher performing tool materials than the traditionally used. Thus, the research presented in this paper focuses on evaluating the active tool wear
Objectives Despite the limited invasiveness of endoscopic transsphenoidal surgery (ETSS), some degree of nasal structure destruction is unavoidable. Our objective was to evaluate sinonasal morbidity and self-reported health before and 6 months after ETSS for pituitary tumors, and to identify possible predictive factors for deterioration in sinonasal health. Design Prospective observational cohort
We study in detail the linear flow of particles on a graph with onevertex and k+1 infinite edges. This has a rich environment with many differentemergent behaviours depending on the system parameters. The abrupt changein the behaviour of the system along a continuous change of the parametersmanifests multiple phase transitions.We discuss the physical interpretation of the considered simple model ofpa
The goal of this work is to specify and investigate suitability of a number of selected permanent magnet synchronous machine (PMSM) topologies to be mounted directly on a low pressure shaft (LPS) of a geared turbofan engine. The starting point of the work is to explore the status of electrical machines for more electric engine in order to study different design aspects when identifying and definin
En av de största utmaningarna i modern tid är att på ett hållbart sätt producera mat och andra varor för en ökande global befolkning, utan att utsätta mark- och vattenresurser för ytterligare belastning och därmed ha negativ inverkan på människors livskvalitet. Storskaligt jordbruk har genererat många fördelar för människan gällande matproduktion, men har även bidragit till många hållbarhetsutmaniA major challenge of our time is to sustainably produce food and other goods for a growing global population, without putting additional pressures on land and water resources and local people’s quality of life. Large-scale agriculture has brought many benefits to humanity in terms of food production but has also caused multiple sustainability challenges, including land and water degradation, defor
With well over 700 000 deaths every year worldwide, kidney disease constitutes an immense health problem for patients and society. The total global number of people with kidney disease regardless of severity amounts to a staggering 600 000 000. Not surprisingly, the total health care expenditure associated with kidney disease is second to no other costs, including oncology/cancer. If acute or chro
AIM: Use of the glucagon-like peptide 1 receptor agonist liraglutide has been shown to reduce weight. Different types of anthropometric measurements can be used to measure adiposity. This study evaluated the effect of liraglutide on sagittal abdominal diameter, waist circumference, waist-to-hip ratio and adiponectin levels in people with type 2 diabetes (T2D) treated with multiple daily insulin in
OBJECTIVE: To develop a psychometrically appropriate brief symptoms measure of carpal tunnel syndrome (CTS). METHODS: Preoperative CTS 11-item symptom severity and 8-item functional status scales from 693 patients (71% women) with CTS were subjected to exploratory factor analysis and item response theory (IRT) analysis yielding a revised CTS symptoms scale. A validation sample of 213 patients (68%
Roman glass from indigenous sites is a key source material for studying the impact of Rome on Iron Age Scotland, but it has never been properly studied. This work fills that gap. This study is based on the Roman glass vessels found on non-Roman/native sites north of Hadrian’s Wall, dated mainly to the Roman Iron Age (AD 10-400 AD). These often-overlooked broken sherds of glass are shown to be pa
Sphingosine 1-phosphate (S1P) has pleiotropic biological functions in the regulation of proliferation, survival, migration, inflammation or angiogenesis. S1P acts as intracellular second messenger, as well as extracellular receptor ligand via five G-protein coupled receptors (S1PR1-5). In the brain, S1P regulates neuronal proliferation or apoptosis, excitatory neurotransmission and neuroglia activ
Vad hände med innebörden av ordet "otrygghet", ett ord med gamla svenska rötter och en tidigare etablerad innebörd, när det amerikanska forskningsfältet "Fear of Crime" introducerade i Sverige och översattes till "Otrygghet"? Syftet med denna avhandling är att beskriva trygghetsforskningens uppkomst, etablering och expansion i Sverige, i syfte att besvara frågor om forskningsdiskursens funktion, sThe purpose of this dissertation is to construct an historical account of the emergence, establishment, and expansion of fear of crime research in Sweden. This dissertation aims to answer questions about the function, spread, and high level of institutional engagement of fear of crime research by analyzing the literature and examining the methodological, theoretical, and epistemological origins of
In recent years, a dispute has arisen within detection and attribution science concerning the appropriate methodology for associating individual weather events with anthropogenic climate change. In recent contributions, it has been highlighted that this conflict is seemingly misconstrued even by those participating in it and actually concerns a mixture of first and second order so-called inductive
Den växande efterfrågan på hållbar och miljövänlig elproduktion, tillsammans med globala osäkerheter, understryker behovet för nationer att uppnå självförsörjande produktion av el. Kärnkraft, som står för cirka 30% av Sveriges elproduktion, spelar en avgörande roll i att leverera fossilfri el. Eftersom många kärnkraftverk närmar sig slutet av sin planerade livslängd är det avgörande att förlänga d
In this study, the influence of drying temperature and pretreatment on the drying kinetics and quality metrics of green banana slices was investigated. The present investigation included the drying of 4 ± 1 mm green banana slices with potassium metabisulfite (KMS) at levels of 0 (control), 0.5%, 1%, and 1.5% in a tray dryer. A numerical optimization method was utilized to optimize the drying rate,
