We study exclusive production of scalar χc0χc(0++) and pseudoscalar ηc charmonia states in proton-proton collisions at the LHC energies. The amplitudes for gg→χc0 as well as for gg→ηc mechanisms are derived in the kT-factorization approach. The pp→ppηc reaction is discussed for the first time. We have calculated rapidity, transverse momentum distributions, and such correlation observables as the d

Lithium depletion and enrichment in the cosmos is not yet well understood. To help tighten constraints on stellar and Galactic evolution models, we present the largest high-resolution analysis of Li abundances A(Li) to date, with results for over $100\, 000$ GALAH (Galactic Archeology with HERMES) field stars spanning effective temperatures $5900\, \mathrm{K} \lesssim T_{\mathrm{eff}}\lesssim 7000

Time, Archaeology and Art – the Pillar of Culture in Lund. The article is an investigation into how archaeologists and artists may relate to time departing from the so-called “Pillar of Culture” at The Cultural Museum in Lund. The pillar is a six m high stratigraphical section from an excavation in Lund 1913. It was exhibited in 1932 in a context of artifacts from the actual excavation. The pillar

This article aims to examine whether it is possible to rework transversearrowheads while still hafted, in order to reuse them. Three series, eachcontaining three arrows, were shot into a target consisting of meat andbone. When possible, the arrowheads were retouched and fired again.The results of the experiments demonstrate that it is possible to reworktransverse arrowheads while they are hafted a

BACKGROUND AND AIM: The drinking water in parts of Ronneby municipality was heavily contaminated with perfluoroalkyl substances (PFAS) for decades. Although PFAS has endocrine-disrupting properties and may interfere with breastfeeding, the supporting epidemiologic literature is conflicting and based solely on populations with background levels of exposure. The effects on breastfeeding in populatio

Redan på 1840-talet hittades en pärlkedja i en grav i Lilla Uppåkra, 1986 hittades ytterligare en vid RAÄ Upppåkra 23, ca 1 km sydöst om Uppåkra kyrka. Dessa två pärlkedjor är bra exempel på hur pärlmodet förändras under 300-talet evt, från mindre uppsättningar med stor variation vad gäller pärltyper till större men mer homogena uppsättningar dominerade av röda, vita och gröna pärlor. I artikeln p

We report an original and straightforward method for both optical and electrical characterization of vertical GaN nanowire arrays epitaxially grown on silicon through visible-infrared spectroscopic ellipsometry methods. For the initial purpose of adding new inputs to the ellipsometry model, focused ion-beam tomography experiments were conducted to extract porosity/depth profiles of these systems.

Background: Conduct disorder (CD), a serious behavioral and emotional disorder in childhood and adolescence, characterized by disruptive behavior and breaking societal rules. Studies have explored the overlap of CD with neurodevelopmental problems (NDP). The somatic health of children with NDP has been investigated; however, the prevalence of these problems in children with CD has not been suffici

The humoral immune response to autologous leukemic cells was investigated in childhood ALL using a 125I protein A binding assay. In 5/7 patients antibodies were demonstrated at diagnosis and in 3/7 cases also after chemotherapy. Sera from 2/3 patients, which bound significantly to autologous leukemic cells, did not bind significantly to autologous remission cells. In allogeneic experiments sera bo

This is the introduction to the anthology Game Love:Essays on Play and Affection. The first 10 pages were written by Jessica Enevold and the ensuing chapter presentations by Esther MacCallum-Stewart. The whole book was edited together by Enevold & MacCallum-Stewart based on an idea by Jessica Enevold. The Introduction explains the background of the anthology, including an introduction to the o
