A comment on [W.J. Olds, A.R. McKinley, M.R. Moore, M.G. Kimlin, In vitro model of vitamin D(3) (cholecalciferol) synthesis by UV radiation: Dose-response relationships, J. Photochem. Photobiol. B: Biol. 93 (2008) 88-93]. The article also discusses some related issues.
Cross sections for elastic and proton-dissociative photoproduction of J/psi mesons are measured with the H1 detector in positron-proton collisions at HERA. The data were collected at ep centre-of-mass energies root s approximate to 318 GeV and root s approximate to 225 GeV, corresponding to integrated luminosities of L = 130 pb(-1) and L = 10.8 pb(-1), respectively. The cross sections are measured
This report summarizes some of the results of studies in our laboratory exploring the development of cognitive, reading and prosodic skills in children with cochlear implantation (CI). The children with CI performed at significantly lower levels than the hearing comparison group on the majority of cognitive tests, despite showing levels of nonverbal ability. The differences between children with C
Background: The intervention; "Continuum of Care for Frail Older People", was designed to create an integrated continuum of care from the hospital emergency department through the hospital and back to the older person's own home. The aim of this study is to evaluate the effects of the intervention on functional ability in terms of activities of daily living (ADL). Methods: The study is a non-blind
The behavior of the surviving population of Lactobacillus plantarum 564 growing in MRS broth after pulsed electric field (PEF) treatments of different intensities was monitored by isothermal calorimetry, optical density and plate counts. Bacterial cells were treated with monopolar square pulses at varying nominal electric field strengths and number of pulses, corresponding to applied energies of 3
The Swedish Board of Fire Research has initiated a pre-study to investigate the possibility to setup a larger research project that would deal with residential fires. Through interviews, literature studies and an initial statistical study, it is clear that there is a need for an umbrella project that focuses on residential fires. The major reason for doing this it that the costs of residential f
Two-dimensional electronic spectroscopy (2D) has been applied to beta-carotene in solution to shine new light on the ultrafast energy dissipation network in carotenoids. The ability of 2D to relieve spectral congestion provides new experimental grounds for resolving the rise of the excited state absorption signal between 18,000 and 19,000 cm(-1). In this spectral region, the pump-probe signals fro
Insulin signaling to the brain is important not only for metabolic homeostasis but also for higher brain functions such as cognition. GABA (c-aminobutyric acid) decreases neuronal excitability by activating GABA(A) channels that generate phasic and tonic currents. The level of tonic inhibition in neurons varies. In the hippocampus, interneurons and dentate gyrus granule cells normally have signifi
Background: Software ecosystems emerged as means for several actors to jointly provide more value to the market than any of them can do on its own. Recently, software ecosystems are more often used to support the development of hardware-dependent solutions. Objectives: This work aims at studying barriers and bridges to participation in an ecosystem with substantial hardware dependencies. Method: W
A search is reported for a neutral Higgs boson in the decay channel H -> Z gamma, Z -> l(+)l(-) (l = e, mu), using 4.5 fb(-1) of pp collisions at root s = 7 TeV and 20.3 fb(-1) of pp collisions at root s = 8 TeV, recorded by the ATLAS detector at the CERN Large Hadron Collider. The observed distribution of the invariant mass of the three final-state particles, m(ll gamma), is consistent with the S
ObjectiveThis study was performed to assess the lipid burden of culprit lesions in non-ST-segment elevation myocardial infarction (non-STEMI) and unstable angina (UA). BackgroundA recent intracoronary near-infrared spectroscopy (NIRS) study showed 85% of STEMI culprit lesions have a maximum lipid core burden index in 4-mm (maxLCBI(4mm))400. Whether culprit lesions in non-STEMI and UA are character
In this paper I discuss how a virtue ethic for the preservation of biodiversity may look like. The starting-point is the virtue ethic proposed by Celia Deane-Drummond. She suggests that the four cardinal virtues of prudence, justice, fortitude and temperance should form the basis of an ethic of nature. Of this four, prudence is the most fundamental. Moreover, Deane-Drummond states that the intelle
Artikeln diskuterar samspelet mellan jordarter, teknologi och "aktörer" och dessa olika faktorers betydelse för bebyggelseutvecklingen. I huvudsak diskuteras utvecklingen av landskapet och bebyggelsen kring Lund och Uppåkra i Skåne (Torna härad och delar av Bara härad). Exempel hämtas även från området kring Skälderviken och en del av Söderåsen (Björnekulla). Artikeln argumenterar för att forsknin
