Biohythane is the gaseous product from the organic matter degradation in two-stage anaerobic digestion (AD) process. It is composed of a mixture of hydrogen and methane, where the hydrogen concentration can be in the range from 10% to 30% v/v. This chapter illustrates the advantages of biohythane use compared to the use of hydrogen and methane, as separate biofuels. The two-stage AD process and th

Nine Ce ii lines have been identified and characterized within the spectral window observed by the Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey (between λ1.51 and 1.69 μm). At solar metallicities, cerium is an element that is produced predominantly as a result of the slow capture of neutrons (the s-process) during asymptotic giant branch stellar evolution. The Ce ii lines

Context. Baade's window (BW) is one of the most observed Galactic bulge fields in terms of chemical abundances. Owing to its low and homogeneous interstellar absorption it is considered the perfect calibration field for Galactic bulge studies. Aims. In the era of large spectroscopic surveys, calibration fields such as BW are necessary for cross calibrating the stellar parameters and individual abu

We report the first detailed chemical abundance analysis of the exoplanet-hosting M-dwarf stars Kepler-138 and Kepler-186 from the analysis of high-resolution (R ∼ 22,500) H-band spectra from the SDSS-IV-APOGEE survey. Chemical abundances of 13 elements - C, O, Na, Mg, Al, Si, K, Ca, Ti, V, Cr, Mn, and Fe - are extracted from the APOGEE spectra of these early M-dwarfs via spectrum syntheses compu

Background and aim: As an increasing number of people are living and ageing with the consequences ofstroke, the rehabilitation and support provided for this group needs to have a long-term perspective. Moreover,to prevent long-term activity limitations and participation restrictions after stroke, increased knowledge is neededregarding how engagement in different types of activities develops beyond

We describe the Sloan Digital Sky Survey IV (SDSS-IV), a project encompassing three major spectroscopic programs. The Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2) is observing hundreds of thousands of Milky Way stars at high resolution and high signal-to-noise ratios in the near-infrared. The Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey is obtaining spa

The present status of Chiral Perturbation Theory in the meson sector is discussed concentrating on recent developments. This write-up contains short discussions on a listing of a few historical papers, the principles behind ChPT, two-flavour ChPT including some comments about the Pion polarizability, three-flavour ChPT with a discussion of the recently found relations as tests of ChPT and prelimin

The Absolut Company har öppnat besökscentret Absolut Home i Åhus och detta har potential att medföra ett stort antal värden för orten. Forskarna har studerat bådeturistaktörers och Åhusbors syn på värden för att ta reda på hur de ställer sig till det nya besökscentret i sin ort.

A short overview of baryon weak decays and our present theoretical understanding is given. The successes and shortcomings of the various approaches are compared.

Recent work by J. Prades and myself on K → ππ is described. The first part describes our method to connect in a systematic fashion the short-distance evolution with long-distance matrix-element calculations taking the scheme dependence of the short-distance evolution into account correctly. In the second part I show the results we obtain for the ΔI = 1/2 rule in the chiral limit.
