Gas rotation, shocks and outflow within the inner 3 kpc of the radio galaxy 3C 33

We present optical integral field spectroscopy $-$ obtained with the Gemini Multi-Object Spectrograph $-$ of the inner $4.0 \times 5.8$ kpc$^2$ of the narrow line radio galaxy 3C 33 at a spatial resolution of 0.58 kpc. The gas emission shows three brightest structures: a strong knot of nuclear emission and two other knots at $\approx 1.4$ kpc south-west and north-east of the nucleus along the ionization axis. We detect two kinematic components in the emission lines profiles, with a "broader component" (with velocity dispersion $\sigma > 150$ km s$^{-1}$) being dominant within a $\sim$ 1 kpc wide strip ("the nuclear strip") running from the south-east to the north-west, perpendicular to the radio jet, and a narrower component ($\sigma < 100$ km s$^{-1}$) dominating elsewhere. Centroid velocity maps reveal a rotation pattern with velocity amplitudes reaching $\sim \pm 350$ km s$^{-1}$ in the region dominated by the narrow component, while residual blueshifts and redshifts relative to rotation are observed in the nuclear strip, where we also observe the highest values of the [N II]/H{\alpha}, [S II]/H{\alpha} and [O I]/H{\alpha} line ratios, and an increase of the gas temperature ($\sim 18000$ K), velocity dispersion and electron density ($\sim 500$ cm$^{-3}$). We interpret these residuals and increased line ratios as due to a lateral expansion of the ambient gas in the nuclear strip due to shocks produced by the passage of the radio jet. The effect of this expansion in the surrounding medium is very small, as its estimated kinetic power represents only $2.6 - 3.0 \times 10^{-5}$ of the AGN bolometric luminosity. A possible signature of inflow is revealed by an increase in the [O I]/H{\alpha} ratio values and velocity dispersions in the shape of two spiral arms extending to 2.3 kpc north-east and south-west from the nucleus.Comment: 16 pages, 14 figures, accepted by MNRA

Congenital granular cell tumor (congenital epulis) : a lesion of multidisciplinary interest

Congenital granular cell tumor (CGCT), or congenital epulis, is an uncommon benign soft tissue lesion that usually arises from the alveolar mucosa of neonates and may cause respiratory and feeding problems. We report a case of a 3- day-old female newborn, who presented an intraoral tumor mass which was protruding from her mouth, compromising feeding. Under general anesthesia, the lesion was completely removed and the patient had an uneventful postoperative course. Clinical features and treatment approaches are presented and discussed, emphasizing the necessity of a multidisciplinary approach in such cases

Feeding and Feedback in the Inner Kiloparsec of the Active Galaxy NGC2110

We present two-dimensional gaseous kinematics of the inner 1.1 x 1.6kpc^2 of the Seyfert 2 galaxy NGC2110, from optical spectra obtained with the GMOS integral field spectrograph on the Gemini South telescope at a spatial resolution of 100pc. Gas emission is observed over the whole field-of-view, with complex - and frequently double - emission-line profiles. We have identified four components in the emitting gas, according to their velocity dispersion (sigma), which we refer to as: (1) warm gas disk (sigma = 100-220km/s); (2) cold gas disk (sigma = 60-90km/s); (3) nuclear component (sigma = 220-600km/s); and (4) northern cloud (sigma = 60-80km/s). Both the cold and warm disk components are dominated by rotation and have similar gas densities, but the cold gas disk has lower velocity dispersions and reaches higher rotation velocities. We attribute the warm gas disk to a thick gas layer which encompasses the cold disk as observed in some edge-on spiral galaxies. After subtraction of a rotation model from the cold disk velocity field, we observe excess blueshifts of 50km/s in the far side of the galaxy as well as similar excess redshifts in the near side. These residuals can be interpreted as due to nuclear inflow in the cold gas, with an estimated ionized gas mass inflow rate of 2.2 x 10^(-2)Msun/yr. We have also subtracted a rotating model from the warm disk velocity field and found excess blueshifts of 100km/s to the SW of the nucleus and excess redshifts of 40km/s to the NE, which we attribute to gas disturbed by an interaction with a nuclear spherical outflow. This nuclear outflow is the origin of the nuclear component observed within the inner 300pc and it has a mass outflow rate of 0.9Msun/yr. In a region between 1" and 4" north of the nucleus we find a new low sigma component of ionized gas which we attribute to a high latitude cloud photoionized by the nuclear source.Comment: 17 pages, 13 figures, 1 table; accepted for publication in MNRA

Education models used across Europe to train Therapeutic Radiographers/Radiotherapists: a cross-case study

[EN] Interviews with radiotherapy (RT) stakeholders were completed across four European countries to identify the educational models used across Europe and how they affect competencies of Therapeutic Radiographers/Radiotherapists (TR/RTTs). The stakeholders identified the following educational models: Programmes below European Qualifications Framework (EQF) level 6 (EQF4 or EQF5) RT-only BSc programmes (EQF6)Multiple-specialism BSc programmes (EQF6)RT-only apprenticeships (EQF6)Multiple-specialism BSc followed by an MSc (EQF6→EQF7)Integrated masters (EQF7)RT-only pre-registration MSc (EQF7)‘Common trunk’ model (EQF6 or EQF7) Each educational model has its set of advantages and disadvantages, but most  models can be used to achieve the same essential competencies of TR/RTTs. Some models showed weaknesses in their ability to develop adequate RT competencies (low EQF level, low RT-specific content). Regulating the standards of practice at national level ensures that essential competencies are developed across all course programmes, improving the care to RT patients.EACEA (European Education and Culture Executive Agency), University of MaltaCouto, J.; Mcfadden, S.; Mcclure, P.; Bezzina, P.; Hughes, C.
