In the present study we investigate the fate of citalopram (CIT) at neutral pH using advanced water treatment technologies that include O(3), ClO(2) oxidation, UV irradiation and Fenton oxidation. The ozonation resulted in 80% reduction after 30min treatment. Oxidation with ClO(2) removed>90% CIT at a dosage of 0.1mgL(-1). During UV irradiation 85% reduction was achieved after 5min, while Fenton w
This paper presents the manufacturing experience of an outer rotor permanent magnet synchronous machine with four different stators. The advantageous features of powder technology and molding techniques are tested when constructing and manufacturing the stators for a 28-pole 30-slot machine. The selected machine configuration is taking advantages of the concept of the modular windings and at the s
Popular Abstract in Swedish Vad arbetar en analytisk kemist med? Exempel på kemiska analyser är att en idrottsman ska dopingtestas eller att eventuella föroreningar i vattnet från en bäck ska bestämmas. Den analytiska kemistens problemställning är vanligtvis att identifiera (kvalitativ analys) och mäta upp (kvantitativ analys) innehållet i ett prov. Ofta är de intressanta ämneshalterna mycket lågaCapillary electrophoresis is characterised by high separation efficiency, applicability to a wide range of compounds, small sample and solvent consumption and simple instrumentation. To improve sensitivity using on-line absorbance detectors, which are hampered by the short optical path length, sample volumes in the microlitre range were concentrated to nanolitre volumes either off-line or on-line.
In trying to get products out to market, manufacturers of FMCG (Fast Moving Consumer Goods) differentiate themselves through e.g. promotional efforts and display packaging (Point-of-Purchase packaging). For the display packaging, companies turn to contract packagers who are able to supply this service, providing the design, manufacturing and assembly and packing of the display packaging. This pape
Ischemic cerebrovascular disease (CVD) is usually a consequence of atherosclerosis and is the commonest cause of stroke. The identification of risk factors and outcome predictors and the initiation of preventive measures constitute the cornerstone of efforts to reduce the risk of stroke and improve outcome. The trend for long-term outcome after stroke and the predictors of this outcome were evalu
This study analyses the development of the Lao freight logistics sector with a special focus on domestic demand for freight logistics services. Based on empirical data, the study focuses on two main dimensions of the Lao freight logistics sector: (i) the development of a private freight logistics sector since the formulation of the New Economic Mechanism (NEM) that progressively opened the Lao eco
In this thesis, I study representations of summer and winter Olympic Games and Olympic athletes in six Swedish popular magazines 1948-1972. The purpose is to examine the forms of identity produced within the nation as an “imagined community”, in discursive processes where gender, sexuality, ”race”/ ethnicity, class and age/generation intersect and mutually construct each other. The study is inspir
We have analyzed the M-bcr breakpoint position in 133 Philadelphia-positive chronic myeloid leukemia patients and correlated the findings with clinical, hematologic, and cytogenetic data. We also investigated the splicing pattern of the BCR-ABL mRNA in 30 patients, using reverse transcriptase PCR. No statistically significant differences were found between breakpoint position within M-bcr and clin
The removal of color and chemical oxygen demand (COD) from simulated dye wastewater containing Acid Orange II was experimentally investigated using coagulation-electrooxidation. Two kinds of coagulation methods, ferrous-mediated coagulation and electrocoagulation were tested as pretreatment. The electrooxidation was carried out in a cell with a three-phase three-dimensional electrode using granula
Large segments of the rural Timorese population survive on subsistence farming characterized by simple production methods and low output. Broad-based improvements in Timorese living standards require increased agricultural output. This article discusses what determines agricultural development in Timor-Leste and how such development can be achieved. The main causes of low agricultural output is fo
Governance is hybrid to the extent that it involves several types of stakeholders, jurisdictional domains, and organisational forms. This paper analyses governance of household solid waste management in Sweden from a hybridity perspective, with the City of Helsingborg as example. The empirical material on which the paper is based consists of interviews with politicians, civil servants and manageme
Direct estimates of C:N ratios of ectomycorrhizal (EM) mycelia growing in situ in forest soils have been obtained for the first time. The mycelial samples were collected from sand-filled mesh bags that were buried in the soil and incubated for 12-18 months in two Norway spruce forests in southern Sweden. At harvest the mesh bags were heavily colonized and the mycelia were extracted from the sand w
The purpose of this study was to investigate the early alterations of retinal function, assessed with electrophysiology, in newly onset type 2 diabetes patients without vascular retinopathy. Seventeen patients with newly diagnosed type 2 diabetes (duration 7 ± 3 months), without any vascular retinopathy in fundus photographs, were examined with full-field electroretinogram (ERG) and multifocal ERG
Platelet transfusions are life-saving treatments for many patients with thrombocytopenia; however, their use is generally discouraged in the autoimmune disorder known as immune thrombocytopenia (ITP). We examined whether allogeneic platelet major histocompatibility complex (MHC) class I transfusions affected antiplatelet CD61-induced ITP. BALB/c CD61 knockout mice (CD61(-)/H-2(d)) were immunized a
Recent findings indicate a strong correlation between the risk of future heart disease and the volume of adipose tissue inside of the pericardium. So far, large-scale studies have been hindered by the fact that manual delineation of the pericardium is extremely time-consuming and that existing methods for automatic delineation lack accuracy. An efficient and fully automatic approach to pericardium
Historia i futurum handlar på ett övergripande plan om synen på historieämnet i svensk skola från 1919 till 2011 såsom det kommer till uttryck i styrdokument och lärobokstexter. Den är också en av de första studierna av hur kunskapsutveckling i historia kan uttryckas teoretiskt och hur sådana tankegångar har tillämpats – eller inte tillämpats – på grundskolans och gymnasiets historieämne. I princiFacing an unknown future, the meaning of history is not primarily a fixed set of knowledge about the past, but a well-developed historical consciousness. This is a generic skill, emanating from an understanding of history as something that we are, and at the same time as something that we create. From a historical-cultural perspective, the learning process can be described with a point of departur
Background: Previous research suggests that sleep problems may be an important predictor for chronic widespread pain (CWP). With this study we investigated both sleep problems and fatigue as predictors for the onset of CWP over a 5-year and an 18-year perspective in a population free from CWP at baseline. Methods: To get a more stable classification of CWP, we used a wash-out period, including onl
The Tile Calorimeter is the hadron calorimeter covering the central region of the ATLAS experiment at the Large Hadron Collider. Approximately 10,000 photomultipliers collect light from scintillating tiles acting as the active material sandwiched between slabs of steel absorber. This paper gives an overview of the calorimeter’s performance during the years 2008–2012 using cosmic-ray muon events an
