Comparative study of metals accumulation in cultured in vitro mycelium and naturally grown fruiting bodies of Boletus badius and Cantharellus cibarius
Cantharellus cibarius Fr. (chanterelle) and Boletus badius Pers. (bay bolete) harvested from natural sites in Poland were used to derive in vitro cultures. The optimal medium composition for cultures was developed. Concentrations of the chosen elements (Zn, Cu, Fe, Mg, Ni, and Cd) in mycelium samples were measured by means of atomic absorption spectrometry. Fe concentration in the analyzed mushroom materials was in the range 215.4–680.3 μg/g dry weight. Mean values of Mg were respectively (in micrograms per gram dry weight) 541.8 for mycelium of C. cibarius cultured in vitro and 1,004.1 for C. cibarius fruiting bodies and 928.9 for the mycelium of B. badius cultured in vitro and 906.4 for B. badius fruiting bodies. The mean concentrations of Zn were 442.7 μg/g dry weight in mycelium from in vitro cultures of B. badius and 172.1 in B. badius fruiting bodies and 131.9 in the case of C. cibarius in mycelium from in vitro cultures and 95.5 for the C. cibarius fruiting bodies. Cu exhibited a reversal tendency, i.e., the element concentrations in naturally grown mushrooms were significantly higher (43.57 μg/g dry weight for C. cibarius and 43.54 μg/g for B. badius) than in cultured in vitro mycelium (12.47 μg/g for C. cibarius and 4.17 μg/g for B. badius). Ni was found in lowest concentrations ranging from 0.33 to 1.88 μg/g dry weight. Toxic metal Cd was found in relatively high concentrations in naturally grown species (0.79 μg/g dry weight—1.02). The lowest was the concentration of Cd in C. cibarius mycelium from in vitro culture—0.06 μg/g dry weight—a bit higher than it was in the B. badius mycelium (0.21 μg/g)

Comparative Study of Metals Accumulation in Cultured In Vitro Mycelium and Naturally Grown Fruiting Bodies of Boletus badius and Cantharellus cibarius
APPLICATIONS OF CLOUD COMPUTING SERVICES IN EDUCATION – CASE STUDY
Applications of Cloud Computing in enterprises are very wide-ranging. In opposition, educational applications of Cloud Computing in Poland are someway limited. On the other hand, young people use services of Cloud Computing frequently. Utilization of Facebook, Google or other services in Poland by young people is almost the same as in Western Europe or in the USA. Taking into account those considerations, few years ago authors have started process of popularization and usage of Cloud Computing educational services in their professional work. This article briefly summarizes authors’ experience with selected and most popular Cloud Computing services
VIDEO MATERIALS AS A MEANS OF PROMOTION AND ADVERTISING OF THE FIELDS OF STUDY
In this paper there were presented some information about marketing and advertisement in the aspect of acquiring customers-candidate for studies with the help of the film as a tool of this kind of action. The paper also shows the results of the survey research and their analysis in the scope of expected features which will be characteristic, according to the respondents, for above-mentioned transfer tool
NON-DESTRUCTIVE TESTS OF LOCK TONGUES USED IN ATR-72 AIRCRAFT LANDING GEAR BASED ON MAGNETIC METHOD
The purpose of this work is to highlight the opportunities of using and analyzing process progression of Non-destructive Testing in aeronautical industries and technologies. This paper concentrates on magnetic-fluorescent method, which is used to showcase the practical test of lock tongue installed in ATR-72 aircraft landing gear
THE VIEW OF THE TECHNICAL AND COMPUTER SCIENCE SPECIALIZATION IN THE SURVEY OF THEIR STUDENTS
The article presents the results of the chosen research of Institute of Technology Students of Technical and Computer Science Specialization with use of questionnaire. For the research were chosen students from the last and the first year of study so that we can define the attitude to specialization and university of students who are finishing the study but also we can define expectations of people who had just begin their studies. Collected data were analyzed with the use of SPSS programme
