Inclusive dijet production at low Bjorken-x in deep inelastic scattering

Dijet production in deep inelastic ep scattering is investigated in the region of low values of the Bjorken-variable x (10(-4) < x < 10(-2)) and low photon virtualities Q(2) (5 < Q(2) < 100 GeV2). The measured dijet cross sections are compared with perturbative QCD calculations in next-to-leading order. For most dijet variables studied, these calculations can provide a reasonable description of th

Production Control of a Pulp and Paper Mill

A summary of a study devoted to computerized scheduling of a complex integrated pulp and paper mill is presented. A mathematical model of the mill was built and the scheduling problem was formulated as an optimal control problem for a multivariable deterministic system. The mill is described by a linear, first-order, vectorvalued differential equation. The control system consists of 10 state varia

Quantification of insulin secretion in relation to insulin sensitivity in nondiabetic postmenopausal women.

To evaluate mechanisms underlying the close association between insulin secretion and insulin sensitivity, insulin sensitivity was evaluated by the euglycemic-hyperinsulinemic clamp technique (M/I(clamp)) and insulin secretion was determined from the 75-g oral glucose tolerance test (OGTT) and from the glucose-dependent arginine-stimulation test in 81 nondiabetic postmenopausal women, all aged 61

Porous silicon as a neural electrode material.

The electrical properties of the solid state/fluid (Ringer solution) interface for phosphorous- and boron-doped porous silicon are reported and the benefits of using porous silicon as neural recording electrodes are discussed. The impedance, reactance and resistance for doped porous and planar silicon, in Ringer solution, were compared to gold electrodes. Planar silicon displayed approximately a t

The weevil Brachyderes lusitanicus (F.) is recorded for the first time from Denmark. In 2006 a population was found at Flyvesandet, Agernæs on the north coast of Fyn. The first Danish specimen was a found on the same locality in september 2000, but this has only recently been indetified correct. The second specimen was found in november 2005. Inspired by this finding the site has been visited by s

Periodic minimal surface structures in bicontinuous lipid-water phases and nanoparticles

The accumulated evidence for the existence of periodic minimal surface (PMS) bilayer structure of the bicontinuous cubic phases in lipidwater systems is summarized. There are three fundamental PMS: the G, D, and P types. These three and no others have been observed in lipid-water systems. Due to the so-called Bonnet relation, the PMS structures are isometric conjugates to one another at coexistenc

Living with cancer in old age. Quality of life and meaning.

Popular Abstract in Swedish ”Att leva med cancer som äldre, livskvalitet och upplevelse av mening” Cancer drabbar företrädesvis äldre personer och är en sjukdom som blir vanligare i takt med det stigande antalet äldre i befolkningen. Cancer hos äldre innebär en komplex situation eftersom åldrandet är präglat av stora individuella förändringar med ökande sjuklighet, nedsatt funktionell förmåga, föThe overall aim of this thesis was to investigate quality of life in people aged 75 and older with cancer in relation to age, gender, presence and type of complaints, comorbidity, living conditions, perceived economic situation, sense of coherence, receiving help for daily living and social resources. The aim was also to investigate older people’s experiences and the meaning of living with cancer

Beta-galactosidase from a cold-adapted bacterium: purification, characterization and application for lactose hydrolysis.

The enzyme beta-galactosidase was purified from a cold-adapted organism isolated from Antarctica. The organism was identified as a psychrotrophic Pseudoalteromonas sp. The enzyme was purified with high yields by a rapid purification scheme involving extraction in an aqueous two-phase system followed by hydrophobic interaction chromatography and ultrafiltration. The beta-galactosidase was optimally
