Suröl är en dryck som ökat i populäritet, speciellt bland folk med stort intresse för hantverksöl och mikrobryggerier. Allt fler bryggerier vågar nu att gå utanför sin trygghetszon med att använda jäst av typen Saccharomyces cerevisiae och istället börjar experimentera med bakterier och jäst som tidigare ansetts vara produktförstörande, till exempel olika mjölksyrabakterier och vildjäst. Genom forSour beer is rapidly gaining popularity among people that have an interest in craft beer and the microbrewing scene. This leads to breweries starting to venture outside their comfort zones regarding the more traditional brewing yeast Saccharomyces cerevisiae and instead have started experimenting with different kinds of bacteria and yeast that in a normal process is regarded as spoilage bacteria,

Qualitative measurements of both OH and polycyclic aromatic hydrocarbons (PAH) as well as quantitative data of soot volume fraction f(v) have been obtained in vaporized liquid fuels, with the main goal of providing experimental data for combustion models and numerical mechanism validation. Measurements were carried out in a laminar coflow burner which was designed, built and integrated with an eva

Background : In order to increase access to antiretroviral therapy (ART) in HIV-infected children, paediatric HIV care has been introduced in health centres in Ethiopia, where patients are managed by health professionals with limited training. Objective : To compare outcomes of paediatric HIV care in hospital and health centre clinics and to determine risk factors for death and loss to follow-up (

Purpose: Glucose concentrations are elevated in retinal cells in undiagnosed and in undertreated diabetes. Studies of diabetic patients suggest that retinal function adapts, to some extent, to this increased supply of glucose. The aim of the present study was to examine such adaptation in a model of type 2 diabetes and assess how the retina responds to the subsequent institution of glycemic contro

Nearly all mammalian cells express a set of genes known as clock genes. These regulate the circadian rhythm of cellular processes by means of negative and positive autoregulatory feedback loops of transcription and translation. Recent genomewide association studies have demonstrated an association between a polymorphism near the circadian clock gene CRY2 and elevated fasting glucose. To determine

Popular Abstract in English The aim of this thesis is to examine the role of early life environments for a variety of individual-level health and socioeconomic outcomes in contemporary Sweden. A research framework has recently emerged suggesting that individual long-term wellbeing is, to a large extent, dependent on the establishment of a healthy trajectory of growth and development during the earThe aim of this thesis is to examine the role of early life environments for a variety of individual-level health and socioeconomic outcomes in contemporary Sweden. Ever-expanding human lifespans have contributed to the emergence of novel socio-health phenomena confronting contemporary Swedish society. A new research framework has emerged in the last 30 years suggesting that individuals’ ability t

Accurate and precise chronologies are needed to evaluate the existence and effect of a post-depositional remanent magnetization lock-in process on sedimentary palaeomagnetic records. Here we present lock-in modelling results of two palaeomagnetic records from varved lake sediments (lakes Kalksjon and Gyltigesjon) in Sweden by using model predictions based on archaeomagnetic data. We used the C-14

Using kilometric arrays of air Cherenkov telescopes at short wavelengths, intensity interferometry may increase the spatial resolution achieved in optical astronomy by an order of magnitude, enabling images of rapidly rotating hot stars with structures in their circumstellar disks and winds, or mapping out patterns of nonradial pulsations across stellar surfaces. Intensity interferometry (once pio

Dug trenches in sediment-cored drumlins on the Småland peneplain, southern Sweden, occurring intermixed with rock-cored drumlins, revealed sedimentary successions and facies suggesting that the core sediments were primarily deposited proglacially, both in glaciolacustrine settings as delta-front and more distal deeper-water sediments, and as glaciofluvial braidplain sediments. From the relationshi

Background: The aim of this study was to determine whether relative qualitative and quantitative differences in protein expression could be related to smoke exposure or smoke-induced airway inflammation. We therefore explored and characterized the protein components found in bronchoalveolar lavage (BAL) fluid sampled from either lifelong smokers or never-smokers. Methods: BAL fluid samples obtaine

The ontogenetic development of size heterogeneity and aggression was monitored in commercial culture tanks of yellowtail kingfish (Seriola lalandi Valenciennes). Size heterogeneity increased substantially with the introduction of Artemia as a food source at 12 days post-hatch (DPH), and was correlated with the appearance of aiming behaviour, a precursor to more direct aggressive interactions. Chas

The aim of this research was to analyze the effects and the modes of action of elemental sulfur (So) in bioluminescence and respiration of Vibrio fischeri cells and the enzymes crude luciferase, pure catalase, and alcohol dehydrogenase (ADH). Metallic copper removed sulfur and reduced the toxicity of acetone extracts of sediment samples analyzed in the bioluminescence test. The sulfur inhibition o

Objective: To evaluate whether the duration of the active phase of labor is associated with maternal body mass index (BMI), in nulliparous women with spontaneous onset of labor. Study design: Historical prospective cohort study including 63,829 nulliparous women with a singleton pregnancy and a spontaneous onset of labor, who delivered between January 1, 1995 and December 31, 2009. Data were colle

Popular Abstract in Swedish Prostata cancer är en av de vanligast förekommande cancerformerna hos män i västvärlden och den vanligaste förekommande hos män i Sverige. Årligen diagnosticeras i Sverige ungefär 6000 fall och mer än 2000 avlider. Drygt 70% av alla som drabbas är äldre än 70 år medan endast ett fåtal är yngre än 50 år. Sjukdomen ter sig mycket olika hos olika patienter. En del som drabHuman glandular kallikrein 2 (hK2) is a predominantly prostate produced protein with many similarities to prostate-specific antigen (PSA). Just like for PSA elevated levels of hK2 can be found in men with protate cancer. We created an assay where hK2 in serum could reliably and with negligible cross-reactivity with PSA, be measured down to 0.030 ng/mL. The assay measured free hK2 and hK2 complexe

A paradigm shift is emerging in higher education especially regarding how universities should address personalized and collaborative mobile learning. Experiences from three international benchmarking-projects through the European Association of Distance teaching Universities (EADTU), the European Centre for Strategic Management of Universities (ESMU) and the First dual mode benchmarking club on qu

Popular Abstract in Swedish Populärvetenskaplig sammanfattning Introduktion Adrenokortikotropiskt hormon (ACTH) stimulerar frisättningen av steroid¬hormoner, främst kortisol, från binjurarna. Kortisol är livsnödvändigt och finns alltid i blodet och förhöjs kraftigt vid stress. I början av 90-talet fann vår forskningsgrupp en koppling mellan ACTH och fettomsättningen som inte involverade steroidhAbstract Adrenocorticotrophic hormone (ACTH) has strong and direct lipid-lowering effects in man. All apoB-containing lipoproteins, i.e. VLDL, LDL, Lp(a), are reduced by 25-30%. In contrast, levels of HDL increase about 10%. In hepatic cell cultures, ACTH inhibits expression and secretion of apoB. In this thesis we corroborate that the reduced apoB synthesis, seen in hepatic cell systems, is als

Within the framework of the European Land Arctic Physical Processes project and as part of the Danish Research Council's Polar Program, a study on trace gas exchange in a high-arctic ecosystem was conducted in NE Greenland, May-August 1997. On the basis of carbon dioxide flux measurements from three dominant surface types, this paper reports on the upscaling of such measurements from canopy to lan
