Radio Planetary Nebulae in the Small Magellanic Cloud

We present ten new radio continuum (RC) detections at catalogued planetary nebula (PN) positions in the Small Magellanic Cloud (SMC): SMPS6, LIN 41, LIN 142, SMP S13, SMP S14, SMP S16, J18, SMP S18, SMP S19 and SMP S22. Additionally, six SMC radio PNe previously detected, LIN 45, SMP S11, SMPS17, LIN321, LIN339 and SMPS24 are also investigated (re-observed) here making up a population of 16 radio detections of catalogued PNe in the SMC. These 16 radio detections represent ~15 % of the total catalogued PN population in the SMC. We show that six of these objects have characteristics that suggest that they are PN mimics: LIN 41, LIN 45, SMP S11, LIN 142, LIN 321 and LIN 339. We also present our results for the surface brightness - PN radius relation ({\Sigma}-D) of the SMC radio PN population. These are consistent with previous SMC and LMC PN measurements of the ({\Sigma}-D) relation.Comment: Accepted for publication in Astrophysics and Space Scienc

Radio-Continuum study of the Nearby Sculptor Group Galaxies. Part 1: NGC 300 at lambda = 20 cm

A series of new radio-continuum (lambda=20 cm) mosaic images focused on the NGC 300 galactic system were produced using archived observational data from the VLA and/or ATCA. These new images are both very sensitive (rms=60 microJy) and feature high angular resolution (<10"). The most prominent new feature is the galaxy's extended radio-continuum emission, which does not match its optical appearance. Using these newly created images a number of previously unidentified discrete sources have been discovered. Furthermore, we demonstrate that a joint deconvolution approach to imaging this complete data-set is inferior when compared to an immerge approach.Comment: 13 pages, 12 figures, accepted to APSS, new version to correct the missing reference

Importance of transport in prehospital treatment of children with craniocerebral injuries

Introduction. In initial, prehospital, phase of treatment of the injured pediatric patient, transport plays an important role. Objective. The aim of this study was to determine the influence of an adequate transport on the survival rate and final outcome of patients with craniocerebral injuries. Method. This study is a clinical, partly prospective, partly retrospective study that includes 60 patients with isolated craniocerebral injuries, aged up to 17 years, and with Glasgow Coma Scale under 8, that did not require surgical treatment. The patients were divided in two groups each with 30 patients. The first group included patients that had adequate prehospital treatment. The second group included patients that had improper prehospital treatment. In both groups the emphasis was on the transport as an important step in initial treatment. Results. There was a statistically significant difference in respect to the mode of transport. In group I there was a greater number of patients transported by specialized emergency vehicles (93.3%) compared to the group II. There was also a difference regarding the time that had elapsed from the moment of injury to the moment of arrival to the hospital - a significantly shorter time in group I. In a group of patients that survived, a greater percentage of patients had been transported by specialized emergency vehicles compared to the group of patients that did not survive. Conclusion. Adequate transport improves the survival rate of the patients with craniocerebral injuries. Also the time that has elapsed from the moment of injury to the moment of arrival to the hospital also influences the survival rate, but the final outcome, too. Transport of pediatric patients is globally neglected. Transport of unstable, critically ill and injured patients accompanied by inexperienced and unspecialized staff is followed an increased mortality rate.
