Dijet events in photon-proton collisions in which there is a large pseudorapidity separation, Deltaeta > 2.5 between the two highest E-T jets are studied with the H1 detector at HERA. The inclusive dijet cross sections are measured as functions of the longitudinal momentum fractions of the proton and photon which participate in the production of the jets, x(p)(jets) and x(gamma)(jets) respectively

Popular Abstract in Swedish Spel om pengar har blivit ett utbrett fenomen i Sverige under 1990-talet, med spelbutiker, spelhörnor i varuhusen, spelmaskiner och spel med kort och på roulette på pubar, pizzerior och restauranger, samt spel på Bingo-Lotto hemma i vardagsrummet. Förutom den ökade tillgången till legala spelformer blir det allt vanligare med spel i miljöer och sammanhang där det inte fGambling has become widely accepted in Sweden during the 1990s, with betting shops, gambling machines and casino-like gambling in pubs and restaurants, as well as Bingo-Lotto in our living rooms. Beyond the expansion in availability of legal gambling opportunities, the most notable change is the shift from gambling in specific venues to gambling in a much wider range of social settings. The conseq

A simple and transparent formalism is presented to treat emission processes in general and resonant emission processes in metals in particular. As an example resonant photoemission in Cu metal is discussed.

In distributed communication networks several nodes interact to carry out services. New telecommunication networks support a variety of services, much different from traditional telephony. Each service has its own so called load profile, which means that the amount of capacity needed to complete a service varies. The services may also have different priorities and quality of service requirements.

We have determined the structure of the homotrimeric dUTPase from Escherichia coli, complexed with an inhibitor and substrate analogue, dUDP. Three molecules of dUDP are found symmetrically bound per trimer, each in a shallow cleft between adjacent subunits, interacting with evolutionary conserved residues. The interactions of the uracil ring and the deoxypentose with the protein are consistent wi

Popular Abstract in Swedish Avhandlingen ”Tingens och tankarnas landskap” söker arkeologiska metoder och teorier för ett humanistiskt närmande av människans tidiga naturumgänge. Med arkeologiskt menas här fokuseringen på de materiella spåren i landskapet, stora som små, naturdanade som människotillverkade. Tidsperspektivet är i huvudsak långtida. I avhandlingen har jag valt ett ekologiskt perspektThe thesis "Tingens och tankarnas landskap" is about the material traces of man and his activities in the past. The study investigates the possibility and methods of describing man’s interaction with nature. Man’s relationship to the physical surroundings is viewed from cultural and social perspectives, using the materials of long-term archaeology. The study also includes a contemporary dimension.

Using LEED and angle resolved photoemission for characterisation we have prepared graphite overlayers with down to monolayer thickness by heating SiC crystals and monitored alkali metal intercalation for the multilayer films. The valence band structure of the monolayer is similar to that calculated for graphene though downshifted by around 0.8 eV and with a small gap at the zone corner. The shift

Objectives: To compare the oldest old (85 years and above) in pain with those with no pain across gender, regarding demographic data, living conditions, social network/support, walking/mobility problems, fatigue, sleeping problems, depressed mood and quality of life (QoL). The aim was also to test how these variables were related to QoL among the oldest old in pain. Methods: The study comprised 16

Urokinase, a serine protease, catalyzes the conversion of plasminogen to plasmin, which is responsible for dissolution of clots in blood vessels. It is an important drug for treatment of thromboembolic disease. Production of urokinase by mammalian cell culture has the following important steps: synthesis, regulation and secretion. Production and accumulation of this product in a bioreactor is a re

Rapporten behandlar utformning av anslutningen mellan yttervägg och platta på mark samt dess inverkan på fukttillståndet i syllar av främst trämaterial. Undersökningen omfattade dels fältmätningar och dels koretiska beräkningar, dessutom gjordes en del laboratorieförsök. Rekommendationer för utformning.

The ovaries of 377 women between the age of 40 and 70 years were measured by ultrasound. About one third of the patients were postmenopausal. Mean value, standard deviation and S.E.M. of the ovarian volume were calculated and related to age, parity and menstrual cycle. Ovarian size decreased with age in all women but bore no relation to parity and day of menstrual cycle in the menstruating group o
