Gamma-gamma absorption in the broad line region radiation fields of gamma-ray blazars. ERRATUM. (2016, ApJ, 821, 102)
(IOP Publishing, 2018)In the published article, our code to evaluate the γγ opacity due to the BLR radiation field contained a numerical error, due to which all opacities are a factor of 2π too low. The corrected Figures 2-4 are shown below. ... -
Gamma-gamma absorption in the γ-ray binary system PSR B1259-63/LS 2883
(IOP, 2017)The observed TeV light curve from the γ-ray binary PSR B1259-63/LS 2883 shows a decrease in the flux at periastron that has not been fully explained by emission mechanisms alone. This observed decrease can, however, be ... -
Gamma-ray and radio properties of six pulsars detected by the Fermi Large Area Telescope
(IOP, 2010)We report the detection of pulsed γ-rays for PSRs J0631+1036, J0659+1414, J0742-2822, J1420-6048, J1509-5850, and J1718-3825 using the Large Area Telescope on board the Fermi Gamma-ray Space Telescope (formerly known as ... -
Gamma-ray blazar spectra with H.E.S.S. II mono analysis: the case of PKS 2155-304 and PG 1553+113
(EDP Sciences, 2017)Context. The addition of a 28 m Cherenkov telescope (CT5) to the H.E.S.S. array extended the experiment’s sensitivityto lower energies. The lowest energy threshold is obtained using monoscopic analysis of data taken with ... -
Gamma-Ray emission from the shell of supernova remnant W44 revealed by the Fermi LAT
(AAAS, 2010)Recent observations of supernova remnants (SNRs) hint that they accelerate cosmic rays to energies close to ~1015 electron volts. However, the nature of the particles that produce the emission remains ambiguous. We report ... -
Gamma-ray observational properties of TeV-detected blazars
(IOP Science, 2013)The synergy between the Fermi-LAT and ground-based Cherenkov telescope arrays gives us the opportunity for the first time to characterize the high-energy emission from blazars over 5 decades in energy, from 100 MeV to 10 ... -
Gamma‐ray pulsar visibility
(AIP, 2005)PSR J0437‐4715 is a millisecond pulsar (MSP) thought to be “pair formation starved” (having limited pair cascades due to magnetic photon absorption). Fortunately the general relativistic (GR) electrodynamical model under ... -
Garcinia mangostana Linn displays antidepressant-like and pro-cognitive effects in a genetic animal model of depression: a bio-behavioral study in the Flinders Sensitive Line rat
(Springer, 2018)There is abundant evidence for both disorganized redox balance and cognitive deficits in major depressive disorder (MDD). Garcinia mangostana Linn (GM) has anti-oxidant activity. We studied the antidepressant-like and ... -
Garden ecosystem services of Sub-Saharan Africa and the role of health clinic gardens as social-ecological systems
(Elsevier, 2018)Rapid urbanization is predicted to take place in Africa in the near future and currently stressed cities will be even more overburdened in terms of pressure on green areas and increasing urban poverty. Effectively planning ... -
Gas chemical adsorption characterization of lanthanide hexafluoroacetylacetonates
(SpringerSpringer, 2017)Newly-established adsorption enthalpy and entropy values of 12 lanthanide hexafluoroacetylacetonates, denoted Ln[hfac]4, along with the experimental and theoretical methodology used to obtain these values, are presented ... -
Gas chromatography-mass spectrometry profiles of urinary organic acids in healthy captive cheetahs ( Acinonyx jubatus )
(Elsevier, 2017)In captivity, cheetahs (Acinonyx jubatus) frequently suffer from several unusual chronic diseases that rarely occur in their free-ranging counterparts. In order to develop a better understanding of their metabolism and ... -
Gas crossover mitigation in PEM water electrolysis: hydrogen cross-over benchmark study of 3M's Ir-NSTF based electrolysis catalyst-coated membranes
(ECS, 2016)In this work we present some preliminary data, such as permeability (gas crossover) of oxygen and hydrogen as a function of current density and other operational variables, aimed at establishing baselines for unmitigated ... -
Gastrointestinal region specific insulin permeation enhancement by Aloe vera gel
(Bentham Science, 2020)Background: The oral administration route is still the most preferred by patients for drug treatment, but is unfortunately not suitable for all drug compounds. For example, protein and peptide drugs (e.g. insulin) are ... -
Gaze behavior in basketball free throws developed in constant and variable practice
(MDPI, 2019)There are a limited number of studies focusing on the mechanisms explaining why variable practice gives an advantage in a novel situation and constant practice in performance in trained conditions. We hypothesized that ... -
The GC-MS metabolomics signature in patients with fibromyalgia syndrome directs to dysbiosis as an aspect contributing factor of FMS pathophysiology
(Springer, 2019)Introduction Fibromyalgia syndrome (FMS) is a chronic pain syndrome. Previous analyses of untargeted metabolomics data indicated altered metabolic profile in FMS patients. Objectives We report a semi-targeted explorative ... -
GC-MS quantification of urinary symmetric dimethylarginine (SDMA), a whole-body symmetric l-arginine methylation index
(Elsevier, 2018)Circulating and excretory NG,N´G-dimethyl-l-arginine (symmetric dimethylarginine, SDMA) and NG,NG-dimethyl-l-arginine (asymmetric dimethylarginine, ADMA) are cardiovascular risk factors. Despite close chemical structures, ... -
GC-MS-based urinary organic acid profiling reveals multiple dysregulated metabolic pathways following experimental acute alcohol consumption
(Nature, 2018)Metabolomics studies of diseases associated with chronic alcohol consumption provide compelling evidence of several perturbed metabolic pathways. Moreover, the holistic approach of such studies gives insights into the ... -
Gearing up impact assessment as a vehicle for achieving the UN sustainable development goals
(Taylor & Francis, 2020)This article reflects on the potential for impact assessment (IA) to be a major vehicle for implementing the UN Sustainable Development Goals (SDGs). While it is acknowledged that the SDGs are intended to deliver broader ... -
Gebed en die vorming van Christelike identiteit in Openbaring
(AOSIS, 2015)The use of prayer in the book of Revelation is analysed. It is illustrated that heavenly prayer is directed to God, but that Jesus is also the subject of praise in contexts of prayer. Specific attention is given to the ... -
