Mid-Ludfordian uranium isotope records distinguish the role of expansive marine anoxia in global carbon cycle dynamics during the late Silurian Lau/Kozlowskii bioevent

The late Silurian Lau/Kozlowskii bioevent marks a time interval with substantial loss in marine biodiversity linked to the largest positive carbon isotope excursion (Mid-Ludfordian CIE; MLCIE) recorded in the Phanerozoic (δ13Ccarb peaks at +8–10‰). The positive δ13C excursion and the extinctions have been linked to increased marine productivity (ocean eutrophication), leading to increased organic

Early screening outcomes before, during, and after a randomized controlled trial with digital breast tomosynthesis

Purpose: To describe and compare early screening outcomes before, during and after a randomized controlled trial with digital breast tomosynthesis (DBT) including synthetic 2D mammography versus standard digital mammography (DM) (To-Be 1) and a follow-up cohort study using DBT (To-Be 2). Methods: Retrospective results of 125,020 screening examinations from four consecutive screening rounds perform

Effect of Different In2O3(111) Surface Terminations on CO2 Adsorption

In2O3-based catalysts have shown high activity and selectivity for CO2 hydrogenation to methanol; however, the origin of the high performance of In2O3 is still unclear. To elucidate the initial steps of CO2 hydrogenation over In2O3, we have combined X-ray photoelectron spectroscopy and density functional theory calculations to study the adsorption of CO2 on the In2O3(111) crystalline surface with

Highly deformed rotational structures in 136Pm

Four highly deformed structures in the odd-odd nucleus 13661Pm75 were observed via the 105Pd(35Cl,2p2n) reaction at 180 and 173 MeV using the GAMMASPHERE γ-ray spectrometer and the Microball charged-particle detector array. Quadrupole moment measurements were performed on all of the bands. In contrast to lighter odd-Ζ Pm and Pr nuclei, bands based on the g9/2[404]9/2 proton orbital were not observ

Archaeological Interactive Report : AIR

Archaeological investigations are by their nature destructive activities. Data documentation is the most important task not to lose the information collected, the interpretations performed and the new knowledge obtained. The Archaeological Interactive Report -AIR is a web platform that provides archaeologists with the tools for documentation, long-term archival, management, visualization, and publ

Marknadens tid : Mellan folkhemskapitalism och nyliberalism

Marknadens tid samlar bidrag från några av Sveriges främsta historiker och fokuserar tiden från 1970-talet och framåt. Varje kapitel utgår från en bild, och i centrum står marknadsvändningen – en mångfacetterad, men samtidigt tydlig process genom vilken marknaden som institution, ideal och metafor blivit ledande inom samhällslivet. Hur kom det sig?Marknadens tid satte stora avtryck i svensk politiThis timely edited volume gather’s a number of Sweden’s leading historians who specialize on the profound transformations of the late 20th Century. Each chapter starts from an image, and at the center is the “market turn” – a multifaceted, but at the same time distinct historical process through which the market as an institution, an ideal, and a metaphor has become a focal point of social life. H

Ta din tid : Gör mindre men bättre

Hur får man tid över till det viktigaste?Hur kan du åstadkomma mer och bättre genom att göra mindre?Samtidshistorikern David Larsson Heidenblad har grävt, sorterat och testat för att kunna lyfta fram de mest välgrundade och effektiva metoderna och principerna – för den som vill koncentrera sig på det väsentliga i livet.Med hjälp av dessa – och andra tips och råd – hjälper han läsaren att klart och

Sum rules and physical bounds for a particulate slab --- transmission

Two different sum rules for transmission of the coherent electromagnetic field by a particulate slab are established. The particles are assumed spherical and randomly located, and the slab is illuminated by a plane wave at normal incidence. These sum rules are obtained assuming the particles are passive scatterers, and satisfy energy conservation and causality conditions. The sum rules are then emTwo different sum rules for transmission of the coherent electromagnetic fieldby a particulate slab are established.
