This work presents a method to optimize multi-product chromatographic systems with multiple objective functions. The system studied is a neodymium, samarium, europium, gadolinium mixture separated in an ion exchange chromatography step. A homogeneous Langmuir Mobile Phase Modified model is calibrated to fit the experiments, and then used to perform the optimization task. For the optimization a mul
Cooking fumes contain aldehydes, alkanoic acids, polycyclic aromatic hydrocarbons, and heterocyclic compounds. The inhalation of cooking fumes entails a risk of deleterious health effects. The aim of this study was to see if the inhalation of cooking fumes alters the expression of inflammatory reactions in the bronchial mucosa and its subsequent systemic inflammatory response in blood biomarkers.
What kind of citizenship education, if any, should schools in liberal societies promote? And what ends is such education supposed to serve? Over the last decades a respectable body of literature has emerged to address these and related issues. In this state of the debate analysis we examine a sample of journal articles dealing with these very issues spanning a twenty-year period with the aim to an
We demonstrate how information about the three-dimensional structure of an object can be extracted from a single Fourier-transform Xray hologram. In contrast to lens-based 3D imaging approaches that provide depth information of a specimen utilizing several images from different angles or via adjusting the focus to different depths, our method capitalizes on the use of the holographically encoded p
Brachytherapy treatment techniques for cancer of the cervix are presented, with examples based on the "Stockholm" technique.
Popular Abstract in Swedish Människan har alltid exponerats för joniserande strålning från radioaktiva ämnen i naturen och i sin egen kropp, samt från kosmisk strålning. Summan av exponeringen från dessa strålkällor blir ungefär 1 mSv per år. Till detta kommer exponering av lungor och luftvägar från radon och radondöttrar, särskilt i inomhusluft. Som jämförelse kan nämnas att en tandröntgen ger enA quarter of a century has elapsed since the catastrophe at the nuclear power plant in Chernobyl. The radioactive fallout affected all the European countries and most severely the three countries of Belarus, Russia and Ukraine. In the aftermath of this devastating event, the scientific knowledge on the various radiological impacts of such a large scale accident and means to remediate these impacts
Background: In Ethiopia, nearly 70% of the population resides in areas prone to malaria infection. The objective of this study is to evaluate the impact of indoor residual spraying (IRS) on the incidence of malaria in East Shoa Zone of Ethiopia. Methods: Data from the registers of malaria cases at Debrezeit Malaria Control Center in East Shoa Zone of Ethiopia were collected and analyzed. Records o
Background: Plasma use has increased since studies have suggested that early treatment with blood components in trauma with severe hemorrhage may improve outcome. Plasma is also commonly used to correct coagulation disturbances in non-bleeding patients. Little is known about the effects of plasma transfusion on plasma volume. We report a prospective interventional study in which the plasma volume-
In this Discussion a few points of confusion concerning chirality are clarified. The term chirodescriptive is proposed for such space groups that lack inversion centres, reflection planes, glide planes or rotary-inversion axes and thus can contain enantiopure, chiral objects. It is pointed out that chiral compounds can (and often do) crystallise in non-chirodescriptive space group when they occur
The aim of this study is to analyse the extent of which different types of research funding, gender and type of position have an effect on the size and density of research collaboration networks. The material consists of 3,306 documents by scientists doing cancer research at Lund University, indexed in the Web of Science databases. The author and address fields were analysed, by studying frequenci
Smart specialisation features prominently in the European regional policy context. This paper discusses how the configuration of the regional institutional framework affects smart specialisation dynamics and policy. It elaborates why and how institutional diversity and integration promote entrepreneurial discovery processes, spillovers and agglomeration effects, and thereby structural change in re
A facile and green synthesis of six-membered cyclic carbonates, the potential monomers for isocyanate-free polyurethanes and polycarbonates, was achieved by transesterification of diols with dimethyl carbonate catalyzed by immobilized Candida antarctica lipase B, Novozym (R) 435, followed by thermal cyclization in a solvent-free medium. The difference in the chemospecificity of the lipase for the
High levels of spermatozoa DNA damage hinder fertility in vivo but not in vitro. It is a source of worry that following in vitro fertilization (IVF) spermatozoa DNA damage, if not repaired by the oocyte, might have a negative impact on the offspring. The aim of this study was to assess if a high spermatozoa DNA Fragmentation Index (DFI) is associated with alterations in birthweight (BW) and/or ges
This paper analyses the effect on meal consumption away from home of a point-of-purchase healthy symbol. We base the analysis on a field experiment in a lunch restaurant. Our results suggest that meal consumption does not increase if the meal is labelled with a healthy symbol. Also, the mean nutritional content of meals consumed seems unaffected by the introduction of a healthy-labelled meal on th
This paper extends theories of retail branding and consumer experience of retail stores by bringing consumer culture theory into the field of retailing. Using ethnographic data collection methods (photo-diaries, participant observations, long interviews, artifact collections) we studied the grocery shopping habits and life at home among Swedish middle-class working women with children. The analysi
The clinical classification of hereditary sequence variants identified in disease-related genes directly affects clinical management of patients and their relatives. The International Society for Gastrointestinal Hereditary Tumours (InSiGHT) undertook a collaborative effort to develop, test and apply a standardized classification scheme to constitutional variants in the Lynch syndrome-associated g
This case study analyzes five Swedish printing houses' pricing with respect to their investments in new printing technology. The new printing technology made it possible for the printing houses to market new products and services to meet the demand for shorter delivery times and full service solutions. Although this demand was apparent, the printing houses' opportunities to capitalize on their inv
The G-protein coupled receptor associated protein β-arrestin-1 is crucial for the regulation of numerous biological processes involved in cancer progression, such as intracellular signaling and cell motility. The encoding gene ARRB1 is harbored in the same chromosomal region as the CCND1 gene (11q13). Amplification of CCND1, frequently encountered in breast cancer, often involves coamplification o
