We present the results of the measurements of the detection efficiency for a 4.7 angstrom neutron beam incident upon a detector incorporating a stack of up to five MultiWire Proportional Counters (MWPC) with Boron-coated cathodes. The cathodes were made of Aluminum and had a surface exhibiting millimeter-deep V-shaped grooves of 45 degrees, upon which the thin Boron film was deposited by DC magnet

Popular Abstract in Swedish Diabetes, i dagligt tal även kallat sockersjuka, kännetecknas av konstant förhöjt blodsocker. Sjukdomen ökar lavinartat, och har beskrivits som en av det moderna samhällets stora epidemier. Diabetes förekommer i två huvudsakliga former, typ 1 och typ 2. I typ 1-diabetes, som framför allt drabbar barn och ungdomar, har de insulinproducerande beta-cellerna förstörts av krDefective insulin secretion from the pancreatic B-cells is a central feature in type 2 diabetes (T2D). There is a strong hereditary component in type T2D, but the underlying pathophysiology remains largely unknown. This thesis uses a combination of gene network analysis and cell-physiological techniques to explore the genetic and cellular basis for impaired insulin secretion in T2D. We found that

Fläderskära är en nordamerikansk art som spritt sig till de tempererade delarna av Europa. Introduktionen till Blekinge är intressant, eftersom arten följde med importerad vass från Tyskland, som skulle användas som en s.k. kvävefälla till Kallinge flygplats utanför Ronneby. Fläderskäran förekommer här i ett rikt bestånd och kanske den etablerar sig.

Substance use disorders are regarded as one of the most prevalent, deadly and costly of health problems. Research has consistently found that the prevalence of other psychiatric disorders among those with substance related disorders is substantial. Combined, these disorders lead to considerable disability and health years lost worldwide as well as extraordinary societal costs. Relatively little of

Background and aims: “It’s best to start with air” states the current guidelines on the resuscitation of babies at birth. In a piglet model mimicking severe neonatal asphyxia and circulatory arrest, different aspects of resuscitation were investigated (studies I-III). The hypotheses were that the return of spontaneous circulation (ROSC) would occur faster with the use of oxygen (I and III) or adre

Abstract in UndeterminedSeveral recent works deal with 3D data in mobile robotic problems, e.g. mapping or egomotion. Data comes from any kind of sensor such as stereo vision systems, time of flight cameras or 3D lasers, providing a huge amount of unorganized 3D data. In this paper, we describe an efficient method to build complete 3D models from a Growing Neural Gas (GNG). The GNG is applied to t

Key developments of instrumentation, control and automation (ICA) applications in wastewater systems during the past 40 years are highlighted in this paper. From the first ICA conference in 1973 through to today there has been a tremendous increase in the understanding of the processes, instrumentation, computer systems and control theory. However, many developments have not been addressed here, s

We report a search for first generation scalar leptoquarks using 1.03 fb(-1) of proton-proton collisions data produced by the Large Hadron Collider at root s = 7 TeV and recorded by the ATLAS experiment. Leptoquarks are sought via their decay into an electron or neutrino and a quark, producing events with two oppositely charged electrons and at least two jets, or events with an electron, missing t

MicroRNAs (miRNAs) are a novel class of small noncoding RNA molecules that regulate gene expression by inducing degradation or translational inhibition of target mRNAs. There are more than 500 miRNA genes reported in the human genome, constituting one of the largest classes of regulatory genes. Increasing experimental evidence supports the idea of aberrant miRNA expression in cancer pathogenesis.

Non-governmental organizations (NGOs) are major players in development aid today. It is widely believed they represent civil society and that, for example, the UN and the World Bank would be strengtened if NGOs were given a larger influence over policy formulation and development. As one can hardly speak of an NGO community, the issue of representation is far from easily solved. NGOs often compete

Comparisons were made between two groups of households in a multi-family residential area in order to investigate how oral information through a door-stepping campaign can influence household food waste recycling behaviour from a quantitative as well as qualitative perspective. Source-separation behaviour was assessed both through weakly weighting of all source-separated food waste and dry recycla

Aims: It is well established that the main cause of the development of cardiovascular disease can be found in unhealthy lifestyle habits. In our study, we wanted to explore the long-term predictors of self-reported lifestyle changes in a middle-aged population after screening for cardiovascular risk factors 10 years earlier. Methods: We conducted a 10-year follow-up telephone interview on self-rep

In the US and most European countries, testicular cancer is the most common malignancy in young men aged 20-40 years. Since the introduction of cisplatin-based treatment in the 1970s, more than 95% of the patients are cured. The increasing incidence of testicular cancer and high survival rates, has led to a growing number of testicular cancer survivors (TCSs). As they have a long life expectancy i
