A one-dimensional model of mechanical deformation of compressible chromatography columns is presented. The model is based on linear elasticity and continuum mechanics and is compared to a more complete two-dimensional model and one-dimensional porosity profiles measured by NMR imaging methods. The model provides a quantitative description of compression and the effects of wall support during scale
The aim of this study was to elicit reference data representative of normal findings at transvaginal gray-scale and Doppler ultrasound examination of the uterus and ovaries in postmenopausal women. A total of 144 asymptomatic postmenopausal women with normal findings at clinical gynecological examination were included in the study. They underwent transvaginal sonography including Doppler measureme

It has been proposed that propofol has antiemetic effects even in nonsedative doses. The aim of this study was to investigate whether propofol influences vomiting induced by the dopamine agonist apomorphine. Ten healthy male volunteers received apomorphine infusion (1 mg/min) until vomiting was induced on four different occasions in a randomized order: a) during propofol infusion (2.4 +/- 0.7 mg.k
The first chapter develops a theoretical model of marriage and divorce. The model has two periods and assumes Pareto efficient time allocations. There is a risk of divorce in the second period, which is modeled as exogenously given. The second chapter utilizes the model developed in the previous chapter to analyze the equality between married men and women. Equality is defined as the spouses' rel
STUDY DESIGN. Symptomatic patients were retrospectively analyzed and compared with a control group from an ongoing prospective and consecutive study. OBJECTIVES. To determine the presence and extent of epidural fibrosis in patients with and without recurrent sciatic pain after previous lumbar discectomy, contrast-enhanced magnetic resonance images were evaluated and correlated with surgical findin
The chromosomal location of six barley genes was determined by Southern blot experiments using wheat strains which contained the short or long arm from one of the seven barley chromosomes. The genes analysed encode enzymes that are required for chlorophyll and heme synthesis. Glutamyl-tRNAGlu synthetase, glutamate 1-semialdehyde 2,1-aminotransferase and glutamyl-tRNAGlu reductase are common to bot
Background. The aims of the present study were to (1) analyze preoperative predictors for outcome suggested by Hardman and surgical mortality after open repair and endovascular repair (EVAR) of ruptured abdominal aortic aneurysms (rAAA), and (2) further evaluate the Hardman index in a systematic review. Methods. Patients operated on for rAAA during a 5-year period between 2000 and 2004 were scored
Ulnar shortening is well accepted in the treatment of ulnar abutment but less so in patients with a shortened radius and ulnar-sided wrist pain as a result of a Colles fracture. Sixteen patients with pain and reduced range of movement ( ROM) and a median preoperative ulnar positive variance of 5 mm ( range 0.5 - 11) had 17 osteotomies. Nine were male and seven female with a median age of 35 ( rang
Infantile colic is causing pain and trouble to infants and their parents. Acupuncture is used to relieve the symptoms but is not scientifically tested as treatment for infantile colic. In this study the experiences of parents, whose 68 babies have got acupuncture, were investigated. The way the parents described their babies behaviour and feeding patterns was analysed with content analysis at a ma
Spontaneously opening, chloride-selective channels that showed outward rectification were recorded in ripped-off patches from rat cultured hippocampal neurons and in cell-attached patches from rat hippocampal CA1 pyramidal neurons in slices. In both preparations, channels had multiple conductance states and the most common single-channel conductance varied. In the outside-out patches it ranged fro
In this letter, a novel frequency-multiplication device based on a three-terminal ballistic junction is proposed and demonstrated. A 100 nm-size, three-terminal ballistic junction and a one-dimensional (1-D), lateral-field-effect transistor with trench gate-channel insulation are fabricated from high-electron-mobility GaInAs/InP quantum-well material as a single device. The devices show frequency
Aim To evaluate whether Long-term treatment with a fixed tow dose of warfarin in combination with aspirin improves the prognosis compared with aspirin treatment alone after an acute myocardial infarction (AMI). Methods Patients who were hospitalized for AMI were randomized to either 1.25 mg of warfarin plus 75 mg of aspirin (n=1659) daily or 75 mg of aspirin atone (n=1641). The study was performed
The PIXE technique offers the possibility of scanning a single hair strand longitudinally with a millimetre proton beam for trace elements. However, the accuracy of the method has been questioned since the quantification of the mass concentration has been a serious problem. In this paper a specific beam-hair-detector geometry is assumed, and the correction factor accounting for the proton energy l
The antimalarial drug chloroquine is also used in the prevention of photodermatoses and in patients with inflammatory connective diseases. The drug binds strongly to melanin. Melanocytic activity can be studied by analysis of the urinary markers of eumelanin (6-hydroxy-5-methoxyindole-2-carboxylic acid, 6H5MI-2-C) and phaeomelanin (5-S-cysteinyl-dopa, 5-S-CD). To determine whether chloroquine inte
Popular Abstract in Swedish Under 1100-talet utvecklades inom kanonisk rätt principen att makarnas samtycke är tillräckligt för att skapa ett giltigt äktenskap. Varken familj eller andra auktoriteter, inte ens kyrkliga, hade laglig bestämmanderätt över två personers giftermål. Denna lagstiftning stod i konflikt med det sekulära samhällets uppfattning av äktenskapet och även i vissa fall med kyrkanOne of the most important aspects of the marriage legislation in medieval canon law is the doctrine of free choice. According to this doctrine, established by pope Alexander III in the second half of the twelfth century, the validity of a marriage depended solely on the freely given consent of the parties. Neither family nor witnesses, not even the presence of a priest were necessary to form a val
