Pre-fractionation of a complex mixture of proteins increases the resolution in analytical separations of proteins from cells, tissues or organisms. Here we demonstrate a novel method for pre-fractionation of membrane proteins by a detergent-based aqueous two-phase system. Membrane proteins are strongly under-represented in proteomic studies based on two-dimensional electrophoresis (2-DE). As a mod

We have combined differential absorption lidar (DIAL) measurements of mercury concentrations downwind of a chloralkali plant (Rosignano Solvay) with measurements of wind profiles made with a Doppler Lidar based on modern fibreoptic technology. Since the flux of pollutant is equal to the cross-wind integral of the product of concentration and wind speed, this should permit us to make a more precise

There are needs to find better and more efficient methods to interpolate precipitation data in space and time. Interpolation of precipitation is explored using a self-organizing map (SOM) in a region with large complexity of precipitation mechanisms (northern Iran). The technique is used both for regionalization and for interpolating monthly precipitation for stations with missing data for 1-, 2-,

Elsa af Trolle var en av de många kvinnor som drogs till journalistiken som utkomstmöjlighet under mellankrigstiden. Hon var även översättare och författare men mest lyckad som skribent, särskilt i den långa sviten av naturkrönikor eller -kåserier som publicerades i Aftonbladet under 1930- till 1950-talet.

In this article Hobbes’s view of the commonwealth, and of law and liberty within it, is discussed from the point of view of social ontology. The artificial character of the commonwealth and the constitutive function of the covenant is put in terms of the institutional world being constructed through collective intentionality, which is performative, self-referential, and collective, and which serve

Limitations of the pulse-shape discrimination (PSD) technique - a promising method to identify the charged particles stopped in planar Si-detectors - have been investigated. The particle resolution turned out to be basically determined by resistivity fluctuations in the bulk silicon which cause the charge-collection time to depend on the point of impact. Detector maps showing these fluctuations ha

OBJECTIVE: The study was designed to investigate the prevalence of celiac disease (CD) among 2.5-year-old children in a Swedish urban population with a high incidence of CD.MATERIAL AND METHODS: Six hundred ninety apparently healthy children, born in the 12-month period of July 1992 through June 1993, were screened for immunoglobulin A (IgA) antigliadin antibodies and IgA antiendomysium antibodies

Popular Abstract in Swedish Kavitation uppstår när trycket är så lågt så att vätska övergår till gas och det är ett problem i många vattenkraftverk på grund av att det kan försämra turbinverkingsgraden samt skada närliggande fasta ytor. Denna avhandling behandlar de numeriska svårigheter som man måste komma tillrätta med för att kunna datorsimulera kavitation i vattenturbiner. Dessa beror på den tCavitation is a problem in many hydroelectric power plants since it can cause adverse effects on performance and damage to nearby solid surfaces. The concerns of this thesis are the numerical aspects of flow simulations in cavitating hydraulic turbines which contain several difficulties: turbulent and complex flows, steady and moving parts of the geometry, bubble transport and cavitation developme

Single film examinations (iodine and/or barium) were reviewed in 28 patients who had undergone surgery on the cricopharyngeal muscle due to Zenker diverticula (24 patients), cricopharyngeal muscle incoordination (3 patients) and pharyngoesophageal web (one patient). All patients had had a myotomy which included the cricopharyngeal muscle and up to 3 cm of the cervical esophagus. Lateral and anteri

Gadolinium chelates, intended as intravenous contrast media for magnetic resonance imaging, have been regarded as nonnephrotoxic and recommended to replace iodinated contrast media in patients with azotemia who are undergoing digital subtraction angiography (DSA). High intraarterial doses (up to 220 mmol of gadodiamide) have been used, with a 40% incidence of nephropathy. The authors discourage th

Christina Stead's works resist simplistic categorization, a circumstance which has attracted some critics and exasperated many others. The upsurge of post-colonial and feminist criticism in the 1980s revitalized critical interest in her books. Exuberant intertextuality and an abundance of contradictory literary and ideological discourses - previously often regarded as excesses flawing Stead's lite

In a previous contribution (Stockmann H J 2002 J. Phys. A: Math. Gen. 35 5165), the density of states was calculated for a billiard with randomly distributed delta-like scatterers, doubly averaged over the positions of the impurities and the billiard shape. This result is now extended to the k-point correlation function. Using supersymmetric methods, we show that the correlations in the bulk are a

Background: There is increasing appreciation of gender differences in COPD but scant data whether risk factors for tow lung function differ in men and women. We analysed data from 3 years follow-up in 178 women and 464 men with COPD, participants in the Euroscop Study who were smokers unexposed to inhaled corticosteroids. Methods: Explanatory variables of gender, age, starting age and pack-years s
