Opis:
W artykule zaprezentowano wyniki badań klinicznych drugiej fazy nad bezpieczeństwem i efektywnością przezczaszkowej stymulacji magnetycznej (TMS – Transcranial Magnetic Stimulation) w porównaniu z terapią elektrowstrząsową oraz samodzielną farmakoterapią. Do badań zakwalifikowano 75 pacjentów, których przydzielono losowo do trzech grup. We wszystkich grupach po zastosowaniu terapii stan kliniczny pacjentów wyraźnie się poprawił (objawy depresji ustąpiły). Najlepszy efekt zaobserwowano w grupie poddanej zabiegom elektrowstrząsowym oraz zażywającej leki przeciwdepresyjne. Nie udało się wykazać, że terapia łącząca stymulację magnetyczną z farmakoterapią była bardziej skuteczna od samodzielnego leczenia farmakologicznego. Podjęto próbę wyjaśnienia nieskuteczności przezczaszkowej stymulacji magnetycznej.
The paper presents the results of the 2nd phase clinical examination of the safety and efficiency of the transcranial magnetic stimulation TMS, compared to the electroconvulsive therapy and standalone pharmacotherapy. 75 patients were enrolled into the study. They were divided randomly into three groups. The significant improvement of clinical state (diminishment of depressive symptoms) was achieved in all groups. The best effect was observed in the group of patients treated with the electroconvulsive therapy, combined with the drugs. However, transcranial magnetic stimulation, along with pharmacotherapy did not prove to be more effective than standalone pharmacological treatment. Possible explanations of ineffectiveness of the transcranial magnetic stimulation therapy is given.

Opis:
One of the methods of obtaining energy from renewable sources is the biomass gasification. For economic reasons, and taking into account the security aspects, it is important to ensure that the process is optimal. The gasification process can be optimized regarding the product energy, especially concentration of hydrocarbons and their derivatives or tar substrates, such optimization requires precise knowledge of temperatures in the gasification reactor. The temperatures inside the reactor determine the speed and quality of gasification process and are one of the most important parameters for control and monitoring systems of gasifier operation. Thermocouples are most widely used for temperature monitoring. That is the reason why it is important to acquire precise temperature readout regardless of aging processes. The significance of accurate temperature determining has been demonstrated with the use of a simplified mathematical model of a reactor assuming ideal reagents mixing. The presented mass and energy balance equations have led to determine the temperature changes during the analyzed process. The final equation is a base for the optimization of the gasification process and contains quantity of measured temperature. The main problem is the accuracy of temperature measurement. The authors have developed the in-situ method of diagnostics of thermocouples, that allows determination of the relative deviation of the sensor thermoelectric force during its operation. Besides characteristic parameters such as material properties the model includes the internal heat transfer, as well. The presented diagnostic method consists in determining the electromotive force of a newly installed sensor, and then determination of characteristic parameters using two selected values of testing current. During operation of the monitored sensor, periodic determination of the relative deviation of the Seebeck coefficient is required. This relative deviation should be compared to its permissible level, that is specified for the process being monitored. The proposed method belongs to the class of comparative ones, where the comparison is related to the indications of the same sensor (the new one and in-service). Experimental verification of the presented method was carried out using gasifier with nominal thermal load of 50kW, fed with wood pellets. The temperature of synthesis gas was measured by the two sensors, the reference sensor and the second one, that was driven by pulses of a testing current. For both current directions the thermoelectric force has been determined. The difference of the obtained electromotive forces is diagnostic information, that is needed to calculate the relative change of the Seebeck coefficient. The proposed solution allows diagnosing thermocouples located in confined areas. Moreover, additional benefit is the possibility of sensors diagnosis without stopping the process being monitored. It is important for both economic and technological reasons.

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:
A thermal decomposition of a cobalt-lanthanum catalyst precursor containing a mixture of cobalt and lanthanum compounds obtained by co-precipitation were studied using thermal analysis coupled with mass spectrometry (TG-MS). Studies revealed that the calcination in air at 500°C is sufficient to transform the obtained cobalt precipitate into Co3 O4 , but it leads to only partial decomposition of lanthanum precipitate. In order to obtain Co/La catalyst precursor containing La2 O3  the calcination in air at the temperature about 800°C is required. However, it is unfavorable from the point of view of textural properties of the catalyst precursor. A strong effect of storage conditions on the phase composition of the studied cobalt-lanthanum catalyst precursor, caused by the formation of lanthanum hydroxide and lanthanum carbonates from La2 O3  when contacting with air, was observed.

Opis:
In modern research on catalysts for NH3&enspsynthesis a lot of attention is paid to cobalt. In this work the new catalytic systems based on cobalt are presented. Unsupported cobalt catalysts singly promoted (La or Ba) and doubly promoted (La and Ba) were prepared and tested in NH3&enspsynthesis reaction under commercial synthesis conditions. Characterization studies revealed that lanthanum plays a role of a structural promoter, which improves the surface of catalyst precursors and prevents from sintering during calcination. However, lanthanum has a negative effect on the reduction of cobalt oxide, but the addition of barium promoter (Co/La/Ba catalyst) diminishes the negative impact of La. The co-promotion of cobalt with lanthanum and barium results in the increasing of the active phase surface and improvement of its activity in NH3&enspsynthesis.

Opis:
All tree breeders cope with the same challenge of the very long time interval of a single breeding cycle. What is more, trees are long−lived, with desirable breeding traits expressing late during their life cycle. Increasing problems with climate change, globalization or economic growth have forced us to accelerate tree breeding and improve selection precision, both of which can be achieved by genomic selection (GS). The idea of GS was introduced nearly 20 years ago as an extension of marker−assisted selection (MAS) in order to advance breeding technologies using genetic markers. Unlike MAS, which exploits only a set of marker−trait associations, GS relies on a high number of genetic markers that are spread throughout the entire length of the genome. All markers effects are assessed simultaneously in order to build a precise model that allows prediction of genetic estimated breeding value of a particular individual using genetic data only. GS has already revolutionized dairy cattle breeding resulting in remarkable improvements across multiple traits and is becoming more and more common in crop production. We now know that genetic architecture of quantitative traits is complex, but recent advances in genomics have made it possible to deal with this problem in an unprecedented way. There are certain concerns regarding GS in forest tree species that include genotype−environment (G×E) interaction and the usefulness of the predictive model built up by GS in the next generation of trees. Nevertheless, experimental results obtained so far have shown that the genetic gain per unit time as well as selection precision can be substantially increased. Here we present the basic principles of GS for forest tree species, giving examples of studies carried out so far and discussing problems and future possibilities that GS may soon open up for forest tree breeders.

Opis:
The black poplar (Populus nigra L.) is an ecologically and economically important tree species, characteristic for floodplain forests in Europe. It is now considered to be endangered in many European countries due to the loss of its natural habitat caused by the development of river engineering and intensive land use management of riverside areas. Multi-stem specimens can be found occasionally in natural black poplar populations. The percentage of such individuals is low, although in some stands it may be over a doz- en percent. The origin of multi-stem trees may be different. As a consequence, trunks being part of such a tree can have the same or different genotypes. The study aimed to find out whether all trunks of multi-stem black poplars are ramets of the same genet or if their genotypes are different, in which case they increase the gene pool of the population. We used 13 microsatellite nuclear markers to analyze the genotypes of 83 trunks belonging to 34 multi-stem black poplar trees from five natural populations from the Oder river valley in Poland. We also performed the sibship analysis of all trunks. The results showed that the trunks being part of the particular individual had distinct genotypes in five trees (14.7%). This indicates that they were formed as a result of the fusion of two genetically different individuals. The sibship analysis revealed that one multi-stem tree was represented by full-sibs. In the remaining four trees the fused trunks were not related. Nevertheless, we found three pairs of half-sibs between different trees that were distant from each other. The majority of the multi-stem trees we examined developed most probably due to the damage to the apical meristem of the main shoot of a single-stem tree. Nevertheless, some of them were indeed formed from two distinct individuals. Therefore, if a particular population consists of a small number of individuals, we recommend to study the genotypic homogeneity of each multi-stem tree.

Opis:
GaN layers grown on ceramics, sapphire or SiC substrates using reactive ion plating method are presented. In reactive ion plating method gallium from a hot source reacts on a heated substrate with nitrogen partially ionized. Rutherford backscattering technique was applied to check the composition of the samples and gallium to nitrogen ratio was found to be close to one. However, Rutherford backscattering studies showed also a remarkable amount of unintentional impurities present in the layers. The structure of GaN was determined using reflection high-energy electron diffraction. It appeared that polycrystal and monocrystal can be grown, depending on growth conditions. Absorption spectra taken on the layers grown on sapphire showed a tail of band to band absorption starting at about 370 nm. Carrier concentration was of the order of 1019-1020 cm$\text{}^{-3}$ at room temperature and did not change much with temperature decrease. No luminescence from the layers was detected, most probably due to high concentration of impurities.
