A measurement of the total pp cross section at the LHC at root s = 7 TeV is presented. In a special run with high-beta* beam optics, an integrated luminosity of 80 mu b(-1) was accumulated in order to measure the differential elastic cross section as a function of the Mandelstam momentum transfer variable t. The measurement is performed with the ALFA sub-detector of ATLAS. Using a fit to the diffe
Studier av palaeostormfloder ger bakgrund till inom vilka intevall stormar av olika storlek förväntas återkomma och träffa olika områden. Denna information kan användas vid modellering, riskbedömning och stadsplanering. Genom att använda de marina ekvationerna av Nittrouer och Sternberg (1981; The formation of sedimentary strata in an allochthonous shelf environment: the Washington continental sheStudies of palaeostorm surges provides background into at what frequencies storms of different magnitudes are expected to return and hit different areas. This information can be used when modelling, doing risk assesments and city planing. Using the marine equations of Nittrouer and Sternberg (1981; The formation of sedimentary strata in an allochthonous shelf environment: the Washington continenta
In this Master’s thesis, two different 28 GHz Doherty power amplifiers (DPAs) are designed, for high power added efficiency (PAE), in the common source (CS) and cascoded topology respectively. The results are analyzed and compared between the two approaches. The DPAs are designed using AWR design environment with virtual source (VS) models of In(Ga)As nanowire transistors and 50 nm gate length. Th
This letter proposes a novel, low-cost, single-layer filtering antenna (filtenna) for wireless communications. The design consists of a compact circular substrate-integrated waveguide (SIW) cavity, a centrally offset metal post for feeding, and a slot radiator for efficient radiation. It is based on an SIW coaxial line and utilizes multiple TM and quasi-TM modes. Unlike filtennas that rely on inli
Background and aims: Gambling disorder (GD) is a behavioral addiction often co-occurring with various mental health concerns, such as problematic pornography use (PPU). The specific impact of the co-occurrence of GD and PPU on treatment outcome remains underexplored. This study aimed to compare the treatment outcomes of individuals actively receiving treatment for GD (n = 172; 3.49% females), dist
Det finns vissa relativt enkla knep när det gäller att försvåra fusk i samband med online-examination på distans. Här nämner vi några stycken som kan vara värda att prova: Går det att bygga in element med en personlig vinkel i frågorna, där studenten måste reflektera eller relatera de ämnesmässiga kunskaperna till sådant som inte är lika för alla? Är det möjligt att lägga till en eller ett par f
A two-step, un-coupled process producing hydrogen (H2) from wheat straw using Caldicellulosiruptor saccharolyticus in a ‘Continuously stirred tank reactor’ (CSTR) followed by anaerobic digestion of its effluent to produce methane (CH4) was investigated. C. saccharolyticus was able to convert wheat straw hydrolysate to hydrogen at maximum production rate of approximately 5.2 L H2/L/Day. The organic
The Swedish pulp and paper industry accounts for half of industrial final energy use in Sweden and 2.3 % in EU-27. On the basis of a disaggregated set of physical production data, a Logarithmic Mean Divisia Index decomposition method is applied to disentangle the influence from activity, structure and energy efficiency improvement (EEI) on its fuel, electricity and primary energy use. An extended
We present a detailed experimental and numerical study of the structural and dynamical properties of salt-free lysozyme solutions. In particular, by combining small-angle X-ray scattering (SAXS) data with neutron spin echo (NSE) and rheology experiments, we are able to identify that an arrest transition takes place at intermediate densities, driven by the slowing down of the cluster motion. Using
P>Few data illustrate the man's reaction to orchidectomy. We investigated long-lasting feelings of loss and uneasiness or shame about the body after removal of a testicle by orchidectomy. We identified 1173 eligible men diagnosed with non-seminomatous testicular cancer treated according to the national cancer-care programmes Swedish-Norwegian Testicular Cancer Group I-IV between 1981 and 2004. We
OBJECTIVE: To determine the impact of improved glycemic control on the development and progression of retinopathy after the institution of insulin therapy in patients with type 2 diabetes and to assess the relation to IGF-1 and hemostatic variables. RESEARCH DESIGN AND METHODS: In a prospective observational study, 45 type 2 diabetic patients were examined at baseline and 1, 3, 6, 12, and 24 month
Popular Abstract in SwedishDDR:s utrikespolitik gentemot Sverige och övriga västeuropeiska stater dominerades sedan början av 1950-talet av en strävan efter diplomatiskt erkännande. Avhandlingen undersöker denna strävan genom att analysera de östtysk-svenska relationerna från 1949 till 1972. Tyngdpunkten ligger på åren 1954-1972. Huvudsakligen har källmaterial från det i DDR styrande kommunistpartSince the early 1950’s the foreign policy of the German Democratic Republic (GDR) towards Sweden and the other Western European states was dominated by a striving for diplomatic recognition. This thesis examines that striving through an analysis of the East German-Swedish relations from 1949 until 1972. The main focus is on the years 1954-1972. The thesis draws mainly on East German archival mater
