Abstract in German Die Methode der ökologischen Kreuzvalidierung dient der Analyse der Beziehung zwischen Entscheidungsmodell und Umwelt. Dabei wird im Gegensatz zu traditionellen Formen der Kreuzvalidierung eine theoretisch-inhaltliche Unterscheidung zwischen Kalibrierungs- und Validierungsdaten vorgenommen. Die Performanz ausgewählter Entscheidungsmodelle bei der Validierung wird in Situationen
Kuhns betydelse för vetenskapsteorin beskrivs kortfattat, från introduktionen av idén om paradigmskiften till hans senare utarbetade uppfattning om vetenskapen som en evolutionär process och skilda vetenskapliga språk som inkommensurabla. Hans inflytande på teologin, särskilt diskussionen om naturvetenskap och teologi, tecknas.
This chapter explores the relationship between unions and skills at the workplace. We argue that the significance of the skills agenda is broadly concomitant with a shift in the labour process beyond mass production into newer trajectories, variously described as post-Fordism, post-industrialism, flexible specialization and new production concepts. Unions are increasingly equating their members’ l
Objective. The purpose of this study was to elucidate whether ambulatory blood pressure (ABPM) performed during a work day and a non-work day had any impact on the night dipping profile. Study design. A crossover randomized ABPM study in primary healthcare was retrospectively analysed for the occurrence of non-dipping (ND), dipping (D) or extreme (XD) nightly dipping. Non-dippers were defined as s
The effect of pre-chamber volume and nozzle diameter on performance of pre-chamber ignition device in a heavy duty natural gas engine has previously been studied by the authors. From the analysis of recorded pre- and main chamber pressure traces, it was observed that a pre-chamber with a larger volume reduced flame development angle and combustion duration while at a given pre-chamber volume, smal
The paper focuses on a suite of fable texts from the modern epoch, the “Fables” of August Strindberg, written in the 1880s. In most of these ten prose fables the protagonists are anthropomorphized animals, one of the facts clearly connecting the suite with the Aesopic tradition, which Strindberg was highly familiar with. The basic message of the Aesopic genre – the rejection of man’s animality as
We have studied the Pd(100)-(√5×√5)-O structure formed by adsorption of 0.8 ML of oxygen by Scanning Tunneling Microscopy (STM), High Resolution Core Level Spectroscopy (HRCLS) and Density Functional Theory (DFT). We show that a recent tensor Low Energy Electron Diffraction (LEED) analysis of the Pd(100)-(√5×√5)-O structure is incompatible with our results from this structure. A new model that is
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
