Opis:
The aim of the investigations was an assessment of the impact of the pulsed high magnetic field on a concentrated spore suspension of F. culmorum fungus, which is a dangerous pathogen of many crops. 5, 10, 15 and 20 pulses of 9 Tesla induction were applied. The pulsed magnetic field limited germination of the tested strain. A significant difference was found for 15 and 20 pulses. Mycelial linear growth was also reduced, as was found both for the inoculation and logarithmic phase of growth in Petri dish culturing, however, no limited mycelium sporulation was observed. There is a potential for the application of the tested physical method – the pulsed high magnetic field to limit the development and harmfulness of F. culmorum.
Celem przeprowadzonych badań była ocena wpływ impulsowego, wysokiego pola magnetycznego na skoncentrowaną zawiesinę zarodników grzyba F. culmorum, groźnego patogena wielu roślin uprawnych. Zastosowano 5, 10, 15 i 20 impulsów pola magnetycznego o indukcji 9 Tesli. Impulsowe pole magnetyczne ograniczyło kiełkowanie badanego szczepu. Istotną różnicę stwierdzono dla 15 i 20 impulsów. Wzrost liniowy grzybni również ulegał ograniczeniu, co stwierdzono zarówno dla inokulacji, jak i fazy logarytmicznej wzrostu w hodowli szalkowej. Nie zaobserwowano jedynie ograniczenia sporulacji grzybni. Istnieje możliwość wykorzystania testowanej metody fizycznej - impulsowego wysokiego pola magnetycznego - do ograniczania rozwoju i szkodliwości F. culmorum.

Opis:
In order to assess the effect of alternating electromagnetic and direct magnetic field on adult Helix aspersa O. F. Müller and their eggs, adults and eggs of H. aspersa maxima Taylor and H. aspersa aspersa O. F. Müller were exposed to such fields with different parameters, and the following life cycle traits were observed: condition of hibernating adults, their survival rate during hibernation and reproduction, egg mass, hatching success, growth rate of hatchlings and body mass of next generation adults. Adults were exposed to sinusoidal, alternating electromagnetic fields of 50 Hz, 100 Hz and 200 μT, and magnetic induction of 50 Hz, as well as a field of 175 μT and 10–1000 Hz (repetition period 80 minutes). Egg batches were exposed to direct magnetic fields of magnetic induction 5 μT and 10 μT and alternating electromagnetic fields of analogous induction and frequency of 50 Hz. The effects varied depending on the parameters of the fields, subspecies and life cycle stage. Adult H. aspersa maxima was more sensitive to the changes in characteristics of electromagnetic field than H. aspersa aspersa, but the two subspecies showed a similar reaction to exposing their eggs to direct or alternating magnetic field. Probably direct field had a greater selection effect compared to alternating field, removing weaker genotypes at embryonic stage; this resulted in a greater mean body mass of the next generation adults. The results are preliminary; further studies, with further modifications of parameters of the fields applied are necessary.

Opis:
Introduction. Metastatic renal cell carcinoma can spread from the primary renal cell carcinoma to other organs, practically to all tissues. Distant metastases – to the tissue of the head and neck – are transferred through the blood and lymph vessels. A case of such a metastasis localized on the palate is relatively rare and therefore poses interesting material for description. Objective. Analysis of a case of cell renal carcinoma meastasis of the palate in a 67-year-old patient, based on clinical observations and medical publications. Conclusion. Clear cell carcinoma metastases to distant organs are often the first sign of a covertly progressing disease of which the primary tumour is localized in the kidney. The treatment is surgical, and prognosis is poor in the case of distant metastases since tumours recur even after a few years.

Opis:
Noonan syndrome is a congenital developmental disorder characterized by short stature, facial dysmorphia, congenital heart defects and skeletal anomalies, with as estimated incidence of between one per 1000 and one per 2500 live births. The aim of our study is to present a case of dental surgical treatment of a child with such disorder. It is widely reported that children with mental disabilities receive less dental and medical care than their nondisabled counterparts. Because of this problem, it seems justified to describe the procedures of treating such children with dental issues, basing on a case of a girl with Noonan Syndrome.

Opis:
Thin films of TiO$\text{}_{2}$-SnO$\text{}_{2}$ and SrTiO$\text{}_{3}$-BaTiO$\text{}_{3}$ are deposited by rf sputtering. The crystallographic and optical properties near the band gap absorption are investigated as a function of film composition. Systematic displacement of the fundamental absorption edge shows different behaviour for amorphous and polycrystalline samples. Results are discussed in terms of the influence of the substitution on the local environment of Ti ion and Me-O distances. Application of XANES and EXAFS is proposed for the studies of solid-state solutions.

Opis:
Nowadays, with the current dynamic development of the automotive industry, we spend more and more time indoors, including in vehicles. The air used for ventilation of the vehicle's cabin comes from the outside. Pollution enters into the vehicle. This research presents the results of tests conducted to assess the exposure of the driver and passengers to volatile organic compounds entering the vehicle with atmospheric air. The simulation researches were conducted on a chassis dynamometer at the Department of Vehicle Engineering at the Faculty of Mechanical Engineering Technical University of Wroclaw and the tests under real conditions, i.e. traffic urban conditions, were taken as well. The measurements were conducted in the centre of Wroclaw during peak hours, when the traffic jam is the most frequent. The measurements were taken in order to organic compounds analysis, which includes gas chromatography. The analysis results were averaged from three measurements to get these studies more reliable. Results show that during mobile tests the vehicle was exposed to much more pollution than in the stationary tests in the simulated conditions of traffic congestion. Therefore, the studies present that the pollution in the traffic congestion is the real danger to drivers.

Opis:
This paper describes a regional overview of selected Central and Eastern European sedimentary basins which hold the unconventional potential for shale gas and shale oil exploration that have attracted interest in the last few years. Organic-rich fine-grained rocks like black and dark-grey shales, mudstones and claystones with varying ages from Cambrian to Miocene are distributed very irregularly across Europe. A long- -lasting, dynamic geological evolution and continuous reconstruction of the European continent resulted in the formation of many sedimentary basins. In some basins, biogeochemical conditions favoured preservation of accumulated organic-rich deposits and led to the generation of hydrocarbons after burial and reaching appropriate maturity levels. Even though shale gas and shale oil exploration in Europe is still in its infancy, shale formations were analyzed before as the source rocks in conventional petroleum systems. Parameters that were used to describe source rocks e.g.: total organic carbon, maturity, thickness, depth of occurrence and areal extent, can indicate preliminary potential for shale gas exploration and allow estimating first resource values. Currently the most intense shale gas exploration takes place in Poland where over 42 wells have been drilled and over 100 concessions for unconventional hydrocarbon exploration have been granted. Upper Ordovician and lower Silurian shales at the East European Craton (Baltic, Lublin and Podlasie basins) are the major targets for unconventional exploration in Poland. In Central and Eastern Europe, evaluation of the unconventional potential of gas-bearing shale formations is carried out also in Ukraine, Lithuania, Austria, Czech Republic, Hungary, Romania, Bulgaria, Moldova and the European sector of Turkey. Despite the fact that each shale rock differs from another by geochemical, petrographical, petrophysical, mechanical and other parameters, some similarities can be seen such as marine type of depositional environment with the predominance of type II kerogen or specific organic matter content. Recoverable resources of shale gas throughout Europe are believed to be as large as 17.67 trillion m3 (624 Tcf) and Poland, Ukraine, France with United Kingdom are thought to have the greatest resources.
