    Opis:
    The rapid development of scanning technology, especially mobile scanning, gives the possibility to collect spatial data coming from maritime measurement platforms and autonomous manned or unmanned vehicles. Presented solution is derived from the mobile scanning. However we should keep in mind that the specificity of laser scanning at sea and processing collected data should be in the form acceptable in Geographical Information Systems, especially typical for the maritime needs. At the same time we should be aware that data coming from maritime mobile scanning constitutes a new approach to the describing of maritime environment and brings a new perspective that is completely different than air and terrestrial scanning. Therefore, the authors, would like to present results of an experiment aimed at testing the possibilities of using mobile scanning at sea. Experiment was conducted in the harbour and the associated environment of neighbouring southern coast of the Baltic Sea.

    Opis:
    Potato starch and corn starch are popular basic raw materials in the processing of biopolymers. One of the processing methods employed in the manufacture of biopolymers is extrusion-cooking technique. With specific parameters and equipment configurations, it is possible to obtain a wide variety of starch-based biopolymers. Loose fill foams are usually produced with the use of polystyrene, but the adverse environmental effects of conventional plastics provide an incentive for the development of new, environmentally friendly raw materials. The aim of the study was to apply the extrusion-cooking technique to prepare starch-based foams from potato starch and corn starch under various extruder screw speeds applied during processing. Process efficiency and energy consumption were also tested during processing. The expanded foams were analysed by means of cutting and compression tests to evaluate selected mechanical properties. The type of starch used and the processing screw speed had an impact on the efficiency and specific energy requirements of the process. The results showed that the screw speed had a significant effect on the cutting forces in the tested foams as well as on its compression properties. Higher hardness of foams was observed when potato starch was used as the basic raw material. Moreover, corn starch foams proved to be more elastic in compression tests.

    Opis:
    The purpose of this study was to examine oral cavity condition, identify microorganisms and evaluate interrelation between protozoans, bacteria and fungi occurring in mouths of insuline treated diabetics. 30 men and women, 25-60 years old, were clinically assessed for their oral cavity condition including pH range. Fifteen of them were the insuline treated diabetics. Swabs taken of different sites of periodontium, dental plaques and dental pockets collected from each patients were used for detection and identification of protozoans, bacteria and fungi. Mucosal inflammation, dental caries, loose teeth, periodontitis were observed in the diabetic patients, whereas the oral cavities were generally in better condition in the control patients. Prevalence of the protozoan parasites Entamoeba gingivalis and Trichomonas tenax was higher in the control patients than in the diabetics (26.6% and 13.3%, respectively). Fecal bacteria Enterococcus fecalis, E. faecium, Klebsiella pneumoniae occurred with significantly higher frequency in the insuline treated patients (60%) than in the control (6.6%). Various Candida albicans strains were more often found in the diabetic (53.2%) than in the control patients (13.3%). The results of our studies show a clear interrelation between alteration of oral health and the occurrence of microorganisms in the insuline treated diabetics. Metabolic disease that causes serious multi-organ disturbances as well as insulinotherapy are the very important factors changing oral cavity ecology of the persons with diabetes mellitus; decresed pH (the average 5.5) may inhibit development of infection with protozoans in the oral cavity of these patients and favour subclinical infections with other microorganisms. Thus, in the insuline treated diabetics, examination of mouths with regard to the occurrence of opportunistic fecal bacteria and fungi, particularly before a therapy with antibiotics is strongly recommended.

    Opis:
    The aim of this work was to study clinical changes and microorganisms in mouths of three patient groups: with congenital disorders (Cd), dialyzed (D) and control (C). Fifty five patients, 20 to 62 years old were assessed. Swabs and samples of periodontal tissue were used for microscopical study to detect of protozoans and for bacterial and fungal cultures. E. Gingivalis and T. tenax were found in all groups. Three out of Cd patients were infected with Acanthamoeba sp. Fecal bacteria were more often found in D than Cd. In all 30-40 years old D patients, fecal bacteria and various strains of C. albicans occurred. We found that systemie diseases favour instabilities in mouths changing interrelations between protozoa, bacteria and fungi. It may increase risk of clinical complications.
