Popular Abstract in Swedish Förmågan att ha tillgång till energi oberoende av ett varierande födointag är livsavgörande. Kroppen har därför på ett högst effektivt sätt löst detta genom att lagra energi i form av fett i fettceller, vilka finns i fettväven. Dessa fettdepåer, vilka utgörs av triglycerider (en triglycerid består av ett glycerol med tre påkopplade fettsyror), byggs upp då födointaget äTriglycerides in the adipocyte are hydrolysed by means of three consecutive reactions through the combined action of two lipases: hormone-sensitive lipase (HSL) and monoglyceride lipase (MGL). HSL catalyses the first and rate-limiting step, i.e. the hydrolysis of triglycerides to diglycerides, and the subsequent hydrolysis of diglycerides and monoglycerides. However, MGL is needed to assure comple

Popular Abstract in Swedish Nattfjärilshannars beteenden och doftupplevelser i feromonplymer Denna skrift avhandlar mekanismerna bakom så kallad förvirringsbekämpning av skadegörande nattfjärilar med hjälp av deras sexualferomon. Nattfjärilar är egentligen en lite felaktig benämning på de fjärilar som inte är dagfjärilar. I Sverige finns det 116 arter dagfjärilar och mer än 2400 arter ’nattfjäriBehaviour of male moths and electrophysiological responses of male pheromone-specific olfactory receptor neurones were studied in two model species, the oriental fruit moth Grapholita molesta and the turnip moth Agrotis segetum. The studies were aimed at elucidating the relative importance of different mating disruption mechanisms. In a wind tunnel study of G. molesta, behavioural response to a r

Improvement of cancer treatment is a major challenge of medical research. Despite the immense efforts made in the improvement of diagnosis and treatment, cancer remains a major concern and cause of morbidity and mortality. Most of the modern anti-neoplastic therapies have severe side effects, and tumor cells often develop drug resistance. There is promise in the new generation of treatments (gene

The surface core-level shifts of Al(111) and Al(100) have been measured using high-resolution core-level photoemission spectroscopy and calculated using density functional theory (DFT). For Al(100), the 2p core-level shift of the first (second) layer was determined to be –75 meV (+20 meV) from experiment and –71 meV (+20 meV) from the DFT calculations. For Al(111), the corresponding values are –27

This chapter deals with the implementation and application of the European Arrest Warrant in Sweden.

Popular Abstract in Swedish Den teoretiska beskrivningen av materians minsta beståndsdelar, den så kallade standardmodellen (SM), överenstämmer med oerhörd noggrannhet med de många och avancerade partikelfysik-experiment som utförts världen över. Trots denna överenstämmelse finns problematiska aspekter hos SM som gör att den inte kommer kunna beskriva fysikaliska fenomen vid högre energier, som änA search for new physics using events with a single photon and missing energy has been made at the DELPHI experiment together with a search for charginos. The results were based on data collected up to and including the final year of 2000. An integrated luminosity of 650 pb^-1 was used in the single photon analysis and 450 pb^-1 in the chargino search. Center-of-mass energies up to 209 GeV were ex

In the exponential Radon transform in R2, the integrals of a scalar function f over lines, with exponential weight functions, are determined. We demonstrate how to define two different kinds of exponential Radon transforms for vector fields in R2 in a natural way. It is shown that having data from these transforms it is possible to reconstruct the vector field uniquely. The motivation for the stud

The welding procedure to seal copper canisters requires variable power input throughout the 45 minute long weld cycle to keep the probe temperature within the process window. By using a cascaded loop that determines the power input requirement, the controller will not be dependent on repeatability in the necessary power input between weld cycles, and the lag time in the probe temperature measureme

Trots att jordbrukslandskapet enbart utgör en liten andel av Sveriges totala yta så är många av de arter som minskat i antal och utbredning knutna till just detta. Om inte förlusten av biologisk mångfald i jordbrukslandskapet bryts kan detta leda till att Sverige inte lever upp till konventionen om biologisk mångfald och till att viktiga ekosystemtjänster i jordbrukslandskapet som pollination och
