Olsztyn, Poland

The University of Warmia and Mazury in Olsztyn was established on 1 September 1999, in accordance with the new Statute of Sejm signed by the President of the Republic of Poland, Aleksander Kwaśniewski, as well as the Minister of National Education, Mirosław Handke, in August of the same year. Its first rector became prof. dr. hab. Ryszard Górecki. The Faculty of Theology was prescribed with the agreement between Polish Episcopate and the government, in the presence of Cardinal Józef Glemp among others. In October the first academic year was inaugurated.The core structure of the University was based upon the agreement between the academic senate of three institutions of higher learning already established in the city: the Academy of Agriculture and Technology, the Pedagogical Institute, and the Warmia Institute of Teology.The University has 16 faculties, out of which 8 hold full academic rights and therefore entitle the university to operate as an autonomous unit.

The present paper reports on A.C. impedance study of hydrogen evolution reaction (HER), carried-out on Pd-modified carbon fibre (CF) and nickel-coated carbon fibre (NiCCF) materials. The HER was examined in 0.5 M H 2SO4 solution for electrochemically deposited Pd on Hexcel 12K AS4C CF and Toho-Tenax 12K50 NiCCF tow materials. Kinetics of the hydrogen evolution reaction was studied at room temperature, over the cathodic overpotential range: -100 to -1200 mV vs. RHE. Corresponding values of charge-transfer resistance, exchange current-density for the HER and other electrochemical parameters for the examined catalyst materials were derived. Thus, Pd modification of CF and NiCCF materials (at ca. 1.5 wt.% Pd) dramatically increased the exchange current-density parameter by about 5300× and 445× for carbon fibre and nickel-coated carbon fibre tows, correspondingly. © 2013, Hydrogen Energy Publications, LLC.

Oil-soluble rosemary extract (OR) and butylated hydroxytoluene (BHT) were added individually and in mixture (MIX) to raw turkey meatballs. After cooking and chilling, samples were air- and vacuum-packaged and frozen stored for 90 days. The synthetic antioxidant, the natural antioxidant and their mixture significantly decreased TBA values. Lipid oxidation was most effectively inhibited by a mixture of BHT and OR during storage in the air, and by BHT in vacuum-packaged samples. A lower rate of the hydrolytic process was observed in BHT samples. All additives stabilized the red colour of turkey meatballs, but samples with a mixture of natural and synthetic antioxidants showed higher a* values than OR samples. Vacuum-packaged turkey meatballs were darker in colour, and the contribution of redness in these samples continued to increase until day 80. OR added alone or in combination with BHT maintained the quality of turkey meatballs during frozen storage, but samples with the synthetic antioxidant were characterized by a non-typical flavour after a longer time of storage. © 2013 Elsevier Ltd.

In fishes, as in other vertebrate species, the DNA component of the telomeres consists of the tandemly repeated TTAGGG motif. The length of the telomeric arrays in fishes ranges from 2 to 25 kb and shortens with age in some of the species. To date, chromosomal distribution of the telomeric DNA sequences has been examined in approximately 80 fish species of which about 42% show additional telomeric hybridization signals far from the chromosomal termini. Based on the chromosomal location, such internally located telomeric repeats may be classified into 4 categories: (1) telomeric DNA sequences located at the pericentromeric regions, (2) interstitial telomeric sites observed between centromeres and the bona fide telomeres, (3) telomeric DNA sequences that scatter along the nucleolus organizer regions, and (4) telomeric DNA repeats interspersed with the entire chromosomes. Most of the pericentromeric and interstitial telomeric sequences in fish are possible relicts of chromosome fusion events. The origin of the telomeric sequences co-localizing with the major rDNA sequences or scattered along the whole chromosomes is not clear. Internally located telomeric repeats are considered as 'hot spots' for recombination and thus may potentially increase the rates of chromosome breaks and rearrangements leading to the various chromosomal polymorphisms in fishes. FISH with telomeric probe applied to metaphase spreads of androgenetic specimens that hatched from eggs exposed to ionizing radiation before insemination enabled the detection of small radiation-induced fragments of maternal chromosomes. Remnants of the irradiated chromosomes were found to be ring chromosomes with the interstitial telomeric signals, telomerless rings, fragments with fused sister chromatids, and linear fragments with telomeres detected at both of their ends. The increasing availability of techniques enabling the study of fish telomeres and telomerase and the easy access to numerous fish species strongly confirm that these animals are promising models in research concerning the role of telomeres and telomerase in vertebrate aging, repair of ionizing radiation-induced DNA double strand breaks, and chromosomal rearrangements. © 2013 S.

The specificity of small organizations (i.e. limited human, financial and technical resources) within the food sector results in problems with adopting the Codex HACCP model used in medium and large-sized businesses. In Poland, it is additionally hindered by the use of a model system mostly based on rigid adherence to quality management protocols based on the ISO 9001 standard. This paper presents how some of the Polish small and/or less-developed food businesses have implemented some elements of the HACCP system. Several practical solutions focusing on the simplification of some system areas such as flow diagrams, hazard analysis, documented procedures and records are described. Moreover, the possibility of applying the GMP/GHP Manual instead of the typical procedures/instructions is presented. © 2013 Elsevier Ltd. Source

This study analyzes changes in the total (intrinsic and acquired) resistance of autochthonous bacteria in a river which is a receiver of treated wastewater. In the analyzed samples, tetracycline contamination levels were low and characteristic of surface water bodies. An increase in the populations of tetracycline-resistant and fluoroquinolone-resistant microorganisms was noted in downstream river water samples in comparison with upstream river water samples, but the above trend was not observed in bacteria resistant to macrolides and β-lactams. The counts of doxycycline-resistant bacteria (DOXR) were significantly correlated with doxycycline levels. The minimum inhibitory concentrations (MICs) for doxycycline in DOXR isolates were higher in downstream river water than in upstream river water samples. The discharge of treated wastewater had no effect on the multi-drug resistance of oxytetracycline-resistant and doxycycline-resistant isolates. The results of the experiment indicate that the presence of doxycycline-resistant bacteria is a robust indicator of anthropogenic stress in river water. © 2012 Elsevier B.V. All rights reserved.
