En god dag på jobben: evaluering av prosjektet "Trygghet og tillit"

Politiets tillit i befolkningen varierer noe i ulike grupper – og ungdom med minoritetsbakgrunn er av dem som har lavest tillit til politiet. Denne utfordringen ønsket man å gjøre noe med, og i 2008 iverksatte POD prosjektet «Trygghet og tillit». Denne rapporten omhandler evaluering av hovedprosjektet som består av 18 gjennomførte tiltak i fire politidistrikter og et særorgan. Tiltakene er valgt ut og gjennomført lokalt og varierer i innhold, omfang, metode og plassering i organisasjonen. Alle tiltakene har en felles målsetting: Å øke tilliten mellom politi og ungdom med minoritetsbakgrunn. I prosjektet har man ikke vært opptatt av at de enkelte tiltakene nødvendigvis skal videreføres i eget distrikt, eventuelt overføres til andre. Men de arbeidsmetodene som er utviklet i løpet av prosjektperioden er det stor enighet om at fortjener å leve videre i etaten etter at prosjektet er avsluttet

Electron-phonon coupling and its evidence in the photoemission spectra of lead

We present a detailed study on the influence of strong electron-phonon coupling to the photoemission spectra of lead. Representing the strong-coupling regime of superconductivity, the spectra of lead show characteristic features that demonstrate the correspondence of physical properties in the normal and the superconducting state, as predicted by the Eliashberg theory. These features appear on an energy scale of a few meV and are accessible for photoemission only by using modern spectrometers with high resolution in energy and angle.Comment: 4 pages, 4 figures, accepted for publication in Phys.

Metformin severely impairs in vivo muscle oxidative capacity in a rat model of type 2 diabetes

Objective: To investigate the effects of metformin on in vivo and in vitro skeletal muscle mitochondrial function in Zucker diabetic fatty (ZDF) rats using 31P magnetic resonance spectroscopy (MRS) and high-resolution respirometry (HRR), respectively. Methods: 12-week old healthy (fa/+) and diabetic (fa/fa) ZDF rats were treated with metformin (0, 30, 100 or 300 mg/kg body weight/day) for 15 days by oral gavage. At day 14, in vivo31P MRS was performed on the tibialis anterior (TA) muscle to measure PCr recovery. At day 15, animals were killed and TA muscles were excised for in vitro HRR measurements. Results: Metformin treatment decreased PCr recovery rates in a dose-dependent manner in both healthy fa/+ and diabetic fa/fa rats. Whereas, the clinical dose of 30 mg/kg/day had no significant effect, PCr recovery rates were ~22% and ~47% decreased at 100 and 300 mg/kg/day. HRR measurements showed a similar, but less pronounced effect of metformin on in vitro mitochondrial function

Functional modes of proteins are among the most robust ones

It is shown that a small subset of modes which are likely to be involved in protein functional motions of large amplitude can be determined by retaining the most robust normal modes obtained using different protein models. This result should prove helpful in the context of several applications proposed recently, like for solving difficult molecular replacement problems or for fitting atomic structures into low-resolution electron density maps. Moreover, it may also pave the way for the development of methods allowing to predict such motions accurately.Comment: 4 pages, 5 figure

Spin polarization of the L-gap surface states on Au(111)

The electron spin polarization (ESP) of the L-gap surface states on Au(111) is investigated theoretically by means of first-principles electronic-structure and photoemission calculations. The surface states show a large spin-orbit induced in-plane ESP which is perpendicular to the in-plane wavevector, in close analogy to a two-dimensional electron gas with Rashba spin-orbit interaction. The surface corrugation leads to a small ESP component normal to the surface, being not reported so far. The surface-states ESP can be probed qualitatively and quantitatively by spin- and angle-resolved photoelectron spectroscopy, provided that the initial-state ESP is retained in the photoemission process and not obscured by spin-orbit induced polarization effects. Relativistic photoemission calculations provide detailed information on what photoemission set-ups allow to conclude from the photoelectron ESP on that of the surface states.Comment: 22 pages with 8 figure
