Opis:
Zulaw, Gouda and Edam cheeses were produced in a cheese dairy with the use of diversified addition of KN0 3 to milk in the amount of: 0.00 - 0.01 - 0.02 %. Occurrence of N-nitrosodimethylamine (NDMA) in all cheeses at the level 0.04-3.79 µg/k:g can be regarded as common. However, in some samples there were found locally high concentrations of NDMA ranging from 18.94 to 168.80 µg/k:g. Variance analysis of NDMA content in all cheeses showed that the amount of KN0 3 additive to milk did not influence the quantity ofNDMA. On the other hand, it was proved that the formation ofNDMA in Zulaw cheese was connected with the duration of its ripening. The quantity of NDMA as a time function c:an be expressed by the equation y=a+bx (a=0.182; b=l.202x 10- 2; error probability = l.192x 10- 1) which is met for about 40 % of observed NDMA content variability in Zulaw cheese. The formation of N-nitrosodiethylamine (NDEA1 N-nitrosodipropylamine (NDEA1 N-nitrosodibutylamine (NDBA1 N-nitrosopiperidine (N-PIP), N-nitrosopyrrolidine (N-PYR) and N-nitrosomorpholine (N-MOR) was occasional and was not related with KN0 3 additive to milk but rather with the degree of cheese ripeness. During the experiments a certain N-nitroso compound was found in Gouda and Edam cheese which has not been described so far and the retention time of which was between those ofNDEA and NDPA.

Opis:
The real contribution of moulds to the pathogenesis of allergic diseases remains unknown, although positive skin prick tests andlor spesific serum IgE to moki allergens can be detected in 1-5% of atopic patients. A significant problem in assesment of exposure to mould allergens, resulting with difficulty in standarization of methods. The aim of this work was to assess the concentration of spores of 8 mould species in flats inhabited by peoples who dont show any symptoms of allergy. The Open Petri Dish (OPD) method involving sedimentation of participles contained in the column of air ower the dish was used to assess the number of spores in 1m3 of indoor atmospheres. All colonies were counted, but only 8 mould species implicated in inhaled allergy were identified, ie.: Alternaria tenuis, Cladosporium herbarum, Helminthosporum halodes, Pullularia pullulans, Penicillium notatam, Rhizopus nigricans, Mucor mucedo, Aspergillus fumigatus. The tests were carried out in 10 flats located in various quarters of the cify of Łódź during three consecutive days of September 1995 between 5:00 pm and 6:04 pm. In analyzing the percentage of spores of each of the eight mould species tested we determined that, independent of fiat and test day, C. herbarum predominated. It is good agreement with the observations of other authors who report that among large quantities of fungi that are detected in late summer, usually C. herbarum spores dominate. This is the season when the incidence of the Cladosporium spores in the atmospheric air increases. Spores of H. halodes were detected least frequently. Our study demonstrated the presence of substantial amounts of mould spores in indoor air of houses in Łódź. The spores belong to species with documented allergenicity, suggesting that they may play a role in development of allergic sensitization in susceptible subjects.

Opis:
The Brillouin light scattering was used to investigate elastic properties of the zinc blende, MBE-grown MnTe layer that was deposited on a (001) GaAs substrate covered by CdTe buffer layer. The three elastic constants of the zinc blende MnTe, namely c$\text{}_{11}$, c$\text{}_{12}$, and c$\text{}_{44}$, were directly determined for the first time from the frequency of the Rayleigh mode, of the pseudo-surface mode, and of the shear horizontal bulk mode traveling parallel to the layer surface. The value of c$\text{}_{11}$ was checked using the frequency of longitudinal bulk waves propagating at different angles from the normal of the layer plane. This value was also independently determined by results of the folding of acoustic phonons, observed for MnTe/CdTe superlattices by the Raman scattering. Finally, the bulk modulus given by the formula B=(c$\text{}_{11}$+2c$\text{}_{12}$)/3 was determined for zinc blende MnTe by ab initio calculations making use of the density functional theory and atomic pseudopotentials; spin polarization of MnTe was taken into account. A satisfactory agreement between theoretical and experimental values was obtained.

Opis:
The electronic band structure of Mn/ZnTe(110) (1×1) has been studied by angle-resolved photoelectron spectroscopy. The sets of spectra were acquired for the clean surface and after in situ deposition of 0.4 ML of Mn, in order to compare the band structures and to reveal changes brought about by the presence of Mn. The experimental band structure diagram of Mn/ZnTe along theΓ-K direction in the Brillouin zone has been derived from the experimental data. Indications of interaction between the Mn 3d states and sp$\text{}^{3}$ bands of the semiconductor are discussed.

Opis:
Due to uniwersity studies young people undergo the process of education, and this in turn changes their behaviours and attitudes. The above mentioned process concerns students of different faculties, also teacher’s faculties. And prospective teachers — having a great influential power — should play a very important role in teaching pro-health attitudes. An the same time it should be emphasized that the more health conscious teachers are, the more effective education will be. Teaching children by exposing them to positive examples should be a basic mechanism in this respect. The question arises whether students — prospective teachers — will be able to set up appropiate examples to follow. The answer to this question seems to be of paramount importance, especially when we take into consideration the fact that health state of Polish citizens is rather poor. Hence the purpose of my research is to assess pro-health attitudes among the students of the University of Zielona Góra.

Opis:
Resonant photoemission spectroscopy, with application of synchrotron radiation, was used to study the valence band electronic structure of clean surface of (EuGd)Te layers. Fano-type resonant photoemission spectra corresponding to the Eu 4d-4f transition were measured to determine the contribution of 4f electrons of Eu$\text{}^{2+}$ and Eu$\text{}^{3+}$ ions to the valence band. The resonant and antiresonant photon energies of Eu$\text{}^{2+}$ ions were found as equal to 141 V and 132 eV, respectively and for Eu$\text{}^{3+}$ ions were found as equal to 146 eV and 132 eV, respectively. Contribution of Eu$\text{}^{2+}$4f electrons was found at the valence band edge while for Eu$\text{}^{3+}$ it was located in the region between 3.5 eV and 8.5 eV below the valence band edge.

Opis:
In the autochthonous Upper Badenian and Lower Sarmatian strata of the Carpathian Foredeep in the Rzeszów area the total organic carbon (TOC) contents vary from 0.02 to 1.26 wt. %(average 0.64 wt. %). Geochemical studies on the dispersed organic matter demonstrated the presence of gas-prone type III (humic) kerogen with small admixtures of algal type II kerogen. At depths less than 2,500 metres the organic matter is immature, thus microbial processes predominated. Methane concentration in natural gases accumulated within Miocene strata usually exceeded 94 vol. %and was generated by microbial reduction of carbon dioxide. Microbial methane was generated mainly during deposition of autochthonous Miocene sediments, but it is possible that this process continues today on a small scale. Higher gaseous hydrocarbons (mainly ethane and propane), which are usually minor constituents (concentrations less than 0.4 vol. %), were generated during diagenetic processes and at the initial stage of the low-temperature thermogenic processes. The slight changes in the geochemical indices of dispersed organic matter and isotope ratios of natural gases with depth are evidence of the homogeneity of deposition of humic organic matter in shallow marine basin during the Late Badenian and the Early Sarmatian and the fact that similar gas generation conditions can be found in the Miocene sequence. Generation and accumulation of microbial methane and the formation and charging multiple stacked reservoirs within the autochthonous Miocene strata, e.g., Palikówka, Jasionka, Stobierna and Terliczka deposits, was facilitated by rhythmic and cyclic deposition of clays and sands and their very high sedimentation rate.

Opis:
Trying to evaluate contemporary messages from the media one can notice – in reference to the value of health - the comparison of positivist traditions and idealistic visions with contradictory standpoints and opinions. It is important to recognize and understand messages of consumer and pop cultures which reflect the pursuit of the world of illusions and dreams. In this world medical and scientific debates frequently blend with popular convictions and myths. It seems that individual and subjective concepts referring to health as a value are becoming decisive categories in designing the concept of freedom. Health, then, is a factor that enters “cultural flexibility” as an element of cultural pressure, connected with concrete physical and psychological results.
