Opis:
Background: The use of simulation-based training is strategic in training medical staff. Aim of the study: The aim of the study was to assess the knowledge and skills of performing neonatal CPR (cardiopulmonary resuscitation) complicated by the presence of meconium in the respiratory tract in two groups of midwives (trained in the traditional tutorial-based model vs simulation-based training) with an interactive neonatal manikin. Material and methods: The knowledge and practical skills assessment was conducted in two groups of midwives. The knowledge of the participants was assessed using both a written test consisting of 25 control questions (5 questions on meconium aspiration syndrome, 20 on neonatal CPR) and practical skills including 12 activities (1-initial, 9-proper, 2-final). The complex “success” indicator was determined based on the effects of patient resuscitation (15 minutes of the scenario), and the reference point for knowledge and skills was to obtain a minimum of 70% correct answers/activities performed, evaluated by three independent experts. Results: In the knowledge test, the respondents scored 17.93 ± 3.11 points out of 25 (71.7%). Practical skills for all respondents were 17.57 ± 2.49 points out of 21 (83.66%), with a tendency to obtain higher points in cleaning of the airways and stimulation of the newborn, and lower for ventilation and the use of an alternative method of intubation. Despite the similar level of practical skills in both groups, only a higher statistical tendency was observed in three out of nine instrumented “proper activities” in the simulation trained midwives. Conclusions: The scenario used by us assessing the knowledge and skills of midwives taught in traditional tutorial-based and simulation-based training, indicates the advantage of acquiring individual competences in a short time using simulation-based training. This increasingly popular scientific model allows the acquisition of “invasive” competencies, but it requires further research.

Opis:
In this paper results of microstructural observations for series of CuZn39Pb2 alloys produced from qualified scraps are presented. The individual alloy melts were differentiated in terms of thermal parameters of continuous casting as well as refining methods and modifications. Structural observations performed by SEM and TEM revealed formation of different types of intermetallic phases including “hard particles”. EDS results show that “hard particles” are enrich in silicon, phosphorus, iron, chromium and nickel elements. Additionally, formation of Al-Fe-Si and Al-Cr in alloy melts was observed as well. It was found that quantity and morphology of intermetallic phases strongly depends upon the chemical composition of raw materials, process parameters, modifiers and refining procedure applied during casting. It was observed that refining process results in very effective refinement of intermetallic phases, whereas modifiers, particularly carbon-based, results in formation of large particles in the microstructure.

Opis:
Trial series of cast alloy MO59 obtained from qualified scrap was investigated. SEM and TEM of resulting precipitates were conducted. The SEM analysis demonstrated the dependence of silicon, phosphorus, iron, chromium and nickel in the composition of the so-called hard precipitates. TEM analysis showed the formation of phase AlFeSi and AlCr. Made studies have shown the important role of the composition of the batch melts brass CuZn39Pb2 type. The analysis of SEM and TEM resulting precipitates pointed to the formation of various forms of divisions, only one of which was described in the literature character of the so-called hard inclusions. The SEM studies demonstrated the dependence of the occurrence of inclusions rich in silicon, phosphorus, iron, chromium and nickel. In contrast, additional TEM analysis indicated the formation of AlFeSi phase type and AlCr. The results of the analyses referred to the structure of the batch. Due to the difficulty of obtaining recycled materials that do not contain these elements necessary to carry out further analyzes in the direction of defining the role of phosphorus in the formation of the so-called hard inclusions.
