We provide a detailed map of the ages and metallicities of turn-off stars in the Milky Way disc based on data from GALAH DR3 and Gaia EDR3. From this map, we identify previously undetected features in the age-metallicity distribution of disc stars and interpret these results as indicating a three-phase formation history of the Milky Way. In the first phase, inner disc stars form along a single age

Radiological staging of rectal cancer dictates subsequent patienttreatment. In early-stage disease, local excision is associatedwith reduced morbidity, mortality, and costs, and maintainsbowel continuity compared with surgery, where the whole orpart of the rectum is resected1–3. Nearly 90 per cent of patientswith T1 rectal cancer have N0 disease and are therefore potentially curable with local res

Flera platser utmed den skånska kusten har idag problem med stranderosion som innebär att havet äter sig inåt land så att stränder och kustlandskap försvinner. När havet stiger förväntas stranderosionen att öka och även kust sträckor som idag inte har problem kan komma att drabbas. Då kustlinjen rör sig inåt land hotas bebyggelse, infra struktur och naturområden, samtidigt som översvämningsrisken Beach erosion is expected to increase as the sea level rises during the coming decades. A retreating coastline threat ens infrastructure, settlements, nature habitats, and at the same time increases the flood risk in low-lying areas. On the Swedish south coast, beach erosion is a problem at present likely to increase due to the sea level rise. For main taining the beaches and protecting the hinter

The linearly polarized photon beam for photonuclear researches has been produced at MAX-lab facility on the base of coherent bremsstrahlung process of electrons in a diamond crystal. Test experiments have been performed at electron energies 143.9 and 192.7 MeV with a diamond crystal 0.1 mm thick. The measured coherent bremsstrahlung spectra demonstrate typical features to be observed at higher ele

Aiming at a feasible industrial scale bioplastic (PHAs) production, a microbial-based PHA-extraction technique was developed and investigated for extraction of different kinds of PHAs and a variety of well-studied producing microbial strains. This technology could make bioplastics production free of the use of organic solvents or other recovery chemicals. The technology allows the co-production of

Creative workers are increasingly called upon to engage affectually with their work through discourses that demand a love or passion for one’s work. In an organisational setting, these discourses can collapse the distance between selves and work, heightening the sense of personal meaningfulness derived from work. However, these discourses can also be used to discipline an organisationally desirabl
