Popular Abstract in Swedish Om flyttfåglarnas magnetiska orientering Fåglarnas flyttning har fascinerat människan i alla tider och det finns fortfarande många obesvarade frågor om hur fåglarna hittar sina flyttningsvägar. Flyttande fåglar använder olika typer av ledtrådar för att orientera sig. Orienteringexperiment har visat att fåglarna använder information från både himlavalvet och jordens magMy thesis focuses on magnetic orientation in migratory birds, i.e. how they can perceive information from the Earth’s magnetic field and use it for orientation. To examine magnetoreception and the function of the light-dependent magnetic compass in birds, I performed behavioural orientation experiments with European robins, Erithacus rubecula, under different spectra and intensities of light. The

Popular Abstract in Swedish Interaktionen mellan laddade polyjoner och motsatt laddade tensid joner har undersökts. Detta har gjorts genom att syntetisera det komplexa saltet (polyjon-tensid jon) och använda detta som utgångspunkt. Olika parametrar för det komplexa saltet har varierats systematiskt och effekten på struktur och vattenupptag har undersökts. Komplexa salt (CxTAPAy) bestående av alkylThe interaction between poylions and oppositely charged surfactant ions has been investigated. This has been done by using the pure complex salt (polyion + surfactant ion) as a point of departure. Different parameters of the complex salt have been varied in a systematic way and the effect on structure and water miscibility has been investigated. Complex salts (CxTAPAy) consisting of alkyl trimethy

Popular Abstract in Swedish Det har varit långt ifrån självklart att kvinnor ska få ägna sig åt högre studier. För hundra år sedan kom t ex medicinska undersökningar som ”visade” att kvinnor som studerade riskerade att bli sterila. I denna bok undersöker Lina Carls hur kvinnors högre studier 1930-1970 beskrivits i samhällsdebatten och i de lokala diskussionerna vid universiteten i Lund och UppsalaThis dissertation’s overall purpose has been to achieve an increased understanding of why women’s integration into universities has progressed so slowly. Through the analysis of the debates on women in higher education I have wanted to see if the main figures reproduce or contradict the discourse. I have had the aim of not only to show how the genus discourse was possibly repeated but also how in

Saccharomyces cerevisiae is able to ferment xylose, when engineered with the enzymes xylose reductase (XYL1) and xylitol dehydrogenase (XYL2). However, xylose fermentation is one to two orders of magnitude slower than glucose fermentation. S. cerevisiae has been proposed to have an insufficient capacity of the non-oxidative pentose phosphate pathway (PPP) for rapid xylose fermentation. Strains ove

We consider two interrelated tasks in a synchronous n-node ring: distributed constant colouring and local communication. We investigate the impact of the amount of knowledge available to nodes on the time of completing these tasks. Every node knows the labels of nodes up to a distance r from it, called the knowledge radius. In distributed constant colouring every node has to assign itself one out

A method for purification of recombinant apolipoprotein A1 in aqueous two-phase systems has been studied. A mutant of apolipoprotein A-I, the Milano variant, was expressed in E. coli. Phase systems containing ethylene oxide (EO)-propylene oxide (PO) random copolymers have been used. These polymers are thermoseparating and have the ability to separate into one water-rich and one polymer-rich phase

The role of peripheral arterial disease in ulcerated diabetic feet has long been underestimated. Progressive claudication, rest pain and the extent of irreversible tissue loss have frequently been indications for revascularization for neuroischaemic ulcers in diabetic patients. These typical ischaemic symptoms are warning signs that are less frequent in diabetic individuals with ischaemia than tho

BACKGROUND: After surgery for oesophageal or gastric cancer, patients suffer from a variety of problems that affect their physical and mental health. Most previous studies on quality of life after this type of surgery are based on quantitative methods, and no studies to date have focused on the patient's subjective experiences of their quality of life from a long-term perspective. OBJECTIVE: To il

Objective: to explore midwives' awareness of and clinical experience regarding domestic violence among pregnant women in southern Sweden. Design: an inductive qualitative design, using focus groups interviews. Setting: midwives with experience of working in antenatal care (ANC) units connected to two university hospitals in southern Sweden. Participants 16 midwives recruited by network sampling an

The isolation of male and female DNA is an important step in the analysis of sexual assault evidence. A vaginal swab with female epithelial cells and male sperm cells is obtained from the female, and it is vital to separate the male and female fractions in order to obtain a single-source DNA profile of the suspect. In the case of a low abundance of sperm cells, it is very important that no cells a

The ability of the proinflammatory cytokine tumor necrosis factor-alpha (TNF-alpha) to influence epithelial interleukin (IL)-8 responses to the intestinal bacterium Lactobacillus plantarum 299v was analyzed in the human HT-29 colonic epithelial cell line. In the absence of TNF-alpha, IL-8 mRNA expression was not detectable by Northern blot analysis in HT-29 cells alone or in HT-29 cells co-culture

Although quality of life has been in the focus of attention for over a decade there are few studies available investigating, how the old and the oldest old experience their quality of life or what quality of life actually means for them? To illuminate this, eleven in-depth interviews were conducted with six women and five men (80+) living in their home. An interpretative hermeneutic phenomenologic

A Surprisingly high degree of structural and compositional dynamics is observed in the system LiBH4-LiCl as a function of temperature and time. Rietveld refinement of synchrotron radiation powder X-ray diffraction (SR-PXD) data reveals that Cl- readily substitutes for BH4- in the Structure of LiBH4. Prolonged heating a sample of LiBH4-LiCl (1:1 molar ratio) above the phase transition temperature a

Multimedia environments consist of verbal and visual representations that, if appropriately processed, allow for the construction of an integrated mental model of the content. Whereas much is known on how students learn from verbal representations, there are fewer insights regarding the processing of visual information, alone or in conjunction with text. The chapter uses a semiotics approach to pr

BACKGROUND: High reproducibility of test measurements is often considered an indication of high reliability of test results. The aim of the current study was to analyse the role of the traditional perimetric reliability indices, False Negative and False Positive responses, and Fixation Losses, as indicators of test reliability in comparison with threshold reproducibility in patients with suspect o

Objective: To study adolescent traumatization and the impact of various types of trauma on dissociative experiences in a sample of 239 Swedish youngsters, 13 to 20 years of age, with diverse socioeconomic and migration backgrounds. We also evaluated whether the type of worst lifetime trauma was associated with higher rates of dissociation.Method: Quantitative and qualitative data on posttraumatic

Aims: A diabetic foot ulcer (DFU) is associated with increased cardiovascular risk and mortality, independently of ulcer etiology (ischemic, neuro-ischemic or neuropathic). Ankle–brachial index (ABI) is the most commonly used test when diagnosing peripheral macrovascular disease and is a well-known marker for increased cardiovascular risk. Transcutaneous oxygen pressure (TcPO2) is considered to be

Residential biomass combustion is a significant source of aerosol particles on regional and global scales influencing climate and human health. The main objective of the current study was to investigate the properties of cloud condensation nuclei (CCN) emitted from biomass burning of solid fuels in different cookstoves mostly of relevance to sub- Saharan east Africa. The traditional three-stone fi

Background: Severe perineal trauma sustained during childbirth is a serious complication since it can lead to both short- and long-term consequences for women. Some of the methods used to prevent perineal injuries have been evaluated in clinical trials, but there are still gaps in the evidence. A new clinical practice has been introduced, adopted by more than half of the maternity wards in Sweden
