The influence of the electrode geometry on the microstructure and corrosion behaviour of Co-Mo nano-crystalline coatings elaborated by electrodeposition is studied. The corrosion behaviour was determined in the Ringer’s solution at 25°C. Electrodeposition mechanisms are also discussed as a function of the electrode geometry. The electrode geometry was found to affect the growth rate and, under certain conditions, the microstructure (existence of channels and pores). It does not have influence on the corrosion behaviour.

The main goal of this study was to investigate possible residua of thymic tissue in 100 adult cadavers with no thoracic pathology known before, by dissection of standard locations of thymic tissue in perithyroid, periaortic, peritracheal and retrotracheal spaces, as well as areas located next to the course of phrenic, vagus and left recurrent laryngeal nerves. Thus obtained tissue samples were studied by two pathologists independently. The remnants of the thymic tissue were found in 61 out of 100 specimens studied. It means that residua of ectopic thymic tissue is common, which may have a huge impact on the results of treatment of many diseases i.e. myasthenia gravis in course of thymoma.

The method of cleaning the ISFET structures after application of a biological substance was developed. There are few references in the literature to cleaning methods of this type of structure for biological applications, but they are relatively complex and difficult to automate. We decided to use resources commonly available in technological laboratories and methods that could be relatively easily automated, which would enable the full potential of ISFET transistors to be used. During the experiments, both acetone and deionized water were tested. The cleaning method was modified and it was checked whether it is possible to use such a method on one transistor more than once and how it affects the transistor's detection capabilities. We managed to obtain an effective method of cleaning ISFETs from biological substances. This method does not allow for obtaining exactly the same state as the original state of the transistor, but it ensures its correct operation and determining the influence of the tested biological substance on the transistor based on the results.

The aim of this study was to determine the beneficial effect of natural substances – enterocin M (Ent M; the proteinaceous substance produced by Enterococcus faecium CCM8558) and sage plant ( Salvia officinalis L.) extract on the production of mucus in the rabbits small intestine and caecum. Sixty four post-weaned rabbits (meat line M91) were divided into three experimental groups (EG – Ent M; SG – sage extract; ESG – combination Ent M with sage extract) and control group (CG). The experiment lasted for 35 days, the natural substances were administered during the first 21 days, Ent M in EG/ESG, sage extract in SG/ESG. The beneficial effect on mucus production quantity occured in the duodenum (p<0.001) and jejunum (p<0.01) in ESG compared to that found in CG on day 21, the prolonged effect in EG in the duodenum (p<0.001) compared to that observed in CG at the end of the experiment and to that in EG on day 21. The novelty of the study is in the application and monitoring the effect of non-rabbit-derived probiotic strain ( Enterococcus faecium CCM8558) bacteriocin – Enterocin M and sage plant extract on mucus quantity (expressed in gram) in different segments of the rabbit small intestine as well as the caecum. The results obtained indicate that supplementation of selected natural substances in the feed has the potent stimulatory effects on mucus production in the rabbit small intestine.

The term extreme rainfall refers to an event during which the thresholds of various hydrological and geomorphic processes are exceeded. The frequency of extremes varies in different climatic zones and in time. The clustering of extreme events happens when the extremes are repeated every 2–3 years, every year or even several times a year. Such clusterings disturb the equilibrium of slope and river channel systems and are separated by periods of stability and recovery. The occurences of clusters are exemplified by present – day processes, historical records and geological records. On this base a model of phases with frequent and rare clusterings during the Holocene was constructed.
