    Opis:
    This paper addresses underwater vegetation in soft water lakes which are influenced by the anthropogenic input of allochtonic dissolved organic matter (DOM) from drained bogs. The aim of this work is to test the hypothesis regarding the role of DOM in shaping the diversity of underwater vegetation. Large differences in underwater vegetation habitats, the limitation of their occurrence to increasingly shallower littoral (the depth of the lower limit of their occurrence decreased from 12 m up to 1 m) and the regression of underwater vegetation were observed in lake types ranging from oligohumic (median (Me) of DOC in water = 2.5 mg C dm-3) to polyhumic (Me of DOC = 35.6 mg C dm-3). The gradual simplification of internal plant patch structure occurred and the Shannon-Weaver diversity index decreased (Me 0.04 → 0.00). Fewer species were observed in the lakes (Me 9 → 2), and the underwater vegetation covered increasingly smaller areas. Species replacement did not occur and no invasive species appeared.

    Opis:
    The characteristics of habitats, individuals and populations of four submerged macrophytes, Lobelia dortmanna L., Isoetes lacustris L., Sphagnum denticulatum Brid. and Fontinalis antipyretica Hedw., were studied in 12 soft water oligohumic lakes which had no inflow of allochtonic DOM and the DOC concentration in the water was <4.0 mg C dm-3 and 13 humic lakes enriched with allochthonous dissolved organic matter (DOM) from drained peat bogs and ranging in DOC water concentration from 4.1 to 44.0 mg C dm-3. The analyses of population disintegration were conducted basing on characteristics of individuals (size, habitat, fertility) and populations (aggregation density index, settlement index of the population area). The settlement index of the population area for Lobelia, Fontinalis, Isoetes, Sphagnum decreased from 8.4 to 6.2 g d.w. m-2, 4.6 to 0.01 g d.w. m-2, 85.4 to <0.001 g d.w. m-2 and 39.3 to 7.2 g d.w. m-2, respectively. Similar trends were observed in aggregation density. The general pattern of the disintegration of populations of these species was always similar. It was independent of the source macrophytes drew resources from or their susceptibility to environmental changes. Individuals began to be eliminated from the deep and central parts of the population area. The remainder of the populations, which persist in the shallowest, best-illuminated part of the area, are themselves endangered by disturbances caused by wavy motion. The only populations of submerged macrophytes which can survive in polyhumic lakes under such conditions are those which are resistant to disturbances common in the shallow littoral (Lobelia dortmanna, Fontinalis antipyretica).

    Opis:
    Changes in population abundance of submerged Sphagnum denticulatum Brid. were studied in an acidic and oligotrophic lake in NW Poland over three years. Individuals were counted in a moss carpet at a depth of 2.5 m on 4 experimental plots, 1 × 1 m each, every 30 days for 36 months using the SCUBA method. PAR intensity was seasonally variable (in winter higher than in summer). Changes in water pH, conductivity, HCO3- concentration, hydration and sediment pH were statistically insignificant (p > 0.05). In the summer of the second study year the moss carpet disappeared almost completely due to a massive bloom of filamentous green algae. Periods of growth, regression and regeneration were observed in the population. The stabilisation of population size took 24 months and followed the pattern: slight fluctuations, then rapid growth and repetition of slight fluctuations. The first stage lasted nine, the second four and the third nine months. These stages took place irrespective of seasons, temperature or PAR intensity. Each rapid increase in abundance lasted about 30 days, at PAR intensity >20% and water temperature ranging from 11 to 16oC (in winter, spring or autumn). The regression stage brought about by the algal bloom started in the second year (in summer) and lasted six months (until the end of January in the third year). The population regeneration began in winter (in February, water temperature 3.0oC, PAR about 20%, ice cover 0.15 m) and finished with the end of spring. The population of S. denticulatum shows a repetitive pattern of abundance variations, which is seriously disturbed in summer, especially after a warm spring, by a massive bloom of filamentous green algae.

    Opis:
    The purpose of this investigation was to examine the influence of sodium hyaluronate (HA) solution on contact lens dehydration and the distribution of water in lens materials. These parameters were measured with gravimetry and differential scanning calorimetry. Five commercial soft contact lenses were used. They represented four FDA (Federal Drug Administration) groups: Air Optix Night&Day Aqua and Acuvue Oasys (I FDA group), Proclear 1-Day (II FDA group), PureVision (III FDA group) and 1-Day Acuvue Moist (IV FDA group). All materials were investigated with two preservative-free HA solutions 0.1% and 0.3%. HA solutions influenced the water content and the dehydration rate of some examined lenses. For three lenses (Oasys, Proclear, Moist) water content of HA lenses was greater than control. Significant slowdown of dehydration rate under HA during the first 20min was observed only for Proclear. PhaseI of dehydration increased significantly with HA solutions in case of Moist and Proclear. For Night&Day and Oasys phaseI appeared under HA solution while it was not present for control lenses. Duration of the phaseI was strongly correlated with water content of the lenses (R2=0.844). The amount of freezable and non-freezable water depended strongly on characteristics of lens material and its interaction with HA molecules. Proclear seems to be the most prone to attach HA molecules which affect changes in dehydration characteristics and water behavior in the polymer. PureVision might be considered as the most resistant to HA in terms of dehydration dynamics and water distribution. All measured parameters seem to be dependent more on material properties than HA concentration.

    Opis:
    Investigated flexible self supporting water tank is made of fibre reinforced rubber and can be used in fire-extinguishing actions to protect buildings and other civil engineering structures. Its self supporting ability results from the air-tight floating flange. Preliminary investigations of the rubber material done in the laboratory and of a prototype tank led to the tank redesign. Deformations of a new tank were measured under its operating conditions with four tons of water inside. Resulting hoop and longitudinal strains exceed four percent and are in agreement with theoretical considerations. Developed measurement methods can be adapted for testing the shell structures and other coverings made of technical fabrics.
    Testowany elastyczny, samonośny zbiornik na wodę wykonany jest z gumy wzmocnionej włóknami i może być użyty w akcjach gaśniczych w celu ochrony budynków i innych obiektów cywilnych. Jego samonośna zdolność wynika ze szczelnego samonośnego kołnierza. Wstępne badania materiałowe gumy przeprowadzone w laboratorium, jak i badania prototypu zbiornika doprowadziły do zmian w jego projekcie. Dokonano pomiarów odkształceń w nowym zbiorniku, zawierającym 4 tony wody, w warunkach prowadzenia akcji. Powstałe obwodowe, jak i wzdłużne odkształcenia przekraczają 4% i zgadzają się z teoretycznymi założeniami. Opracowane metody pomiarów mogą być wykorzystane do testowania konstrukcji łupinowych oraz innych pokryć wykonanych z włókien technicznych.

    Opis:
    Za pomocą dodatku do farszu soli zawierającej radioizotop ²²Na mierzono w kiełbasach, w różnych fazach produkcji i magazynowania zmiany radioaktywności i zawartości suchej substancji tłuszczowej. Wyniki wskazują, że w trakcie dojrzewania i wędzenia dyfuzja jonów ²²Na oraz wody odbywa się w kierunku wewnętrznych i zewnętrznych warstw kiełbas. W trakcie magazynowania jony sodowe kierują się głównie do wnętrza. Dyfuzja jonów ²²Na jest zależna od wielu czynników wśród których główną rolę odgrywa wilgotność (40%). Potwierdzono, że w trakcie badania nie wystąpiło grawitacyjne przemieszczanie jonów sodowych i wody. Obliczono współczynniki dyfuzji jonów ²²Na i wody. Wyniki wskazują, że szybkość przemieszczania wody w trakcie dojrzewania i wędzenia jest 40-krotnie wyższa niż sodu. Szybkość ta obniżała się pod koniec badania do poziomu 4-krotnie wyższego.

    Opis:
    The purpose of this study was to examine the in vitro dehydration characteristics of new and worn conventional and silicone-hydrogel contact lenses. Four contact lens materials were investigated: three conventional hydrogels (etafilcon, nelfilcon, omafilcon) and one silicone-hydrogel (narafilcon). Gravimetric data were obtained with analytical balance with 1 min intervals. Quantitative parameters of water content and dehydration rate were calculated allowing quantitative description of dehydration process. Differential scanning calorimetry was used to monitor changes in water states in samples studied. As expected, dehydration behavior of each material is different in terms of mean dehydration rate values and phases of dehydration. Gravimetric data allowed us to distinguish three phases of dehydration. Interestingly, the effect of the osmolality of storing solutions on dehydration was found – lenses stored in hyperosmotic solutions needed more time to achieve equilibrium with the environment. Effect of wearing on dehydration patterns and water properties was confirmed. In worn samples, a decrease in water content was observed. Additionally, there was a change in water structure after 6 h of wearing in all lenses studied. This behavior may be ascribed to tear film components deposition and changes in surface wettability that appear during wearing.

    Opis:
    The beverage industry is a signifi cant market that is seeing a growth albeit certain types of beverages such as wine and soda-type drinks are seemingly declining. There is certainly seen a growing interest for novel beverages, especially when creating healthy options aiming to support health via enhanced functional food/beverage properties. Furthermore, understanding how the public perceives and makes purchasing decisions towards novel and unconventional options is of key importance. The Soft Seltzer category is an emerging category defi ned as a sparkling waterbased low calorie, no added sugar, no artifi cial sweetener, non-alcoholic, carbonated beverage. In our pilot study herein, we aimed to assess interest and willingness to pay for such a product produced in Sonoma, California, specifically H2O/H2♡, a dealcoholized wine-type beverage enriched with vitamins, potassium, and calcium, using a perception and acceptability study to health-conscious college students in California. Respectivelly, healthy college students were provided an on-line acceptability questionnaire with 38 questions to evaluate the concept of the H2O beverage. Our participants indicated that they would be signifi cantly interested in purchasing such a beverage, while as for willingness to pay, a price for $9.99/4x16oz cans was deemed less than or about what is expected from a majority of participants. Our results taken together demonstrate that there is substantial interest and traction for such a beverage, especially given its natural origin and potential health benefi ts. Further research including tasting and health-related functional properties for the beverage in discussion is suggested. Additionally, lifestyle aspects and nuances beyond alcohol that are important to wine drinkers and other consumers could be delivered by novel beverages, hence aid in their success in the beverage market.

    Introduction and aim. Violation in the salivary glands will inevitably cause changes in periodontium, and periodontitis can disrupt the functioning of the salivary glands. The purpose of the work is to evaluate changes in NO-synthase and arginase activities, pro- and antioxidant balance in rat salivary glands and soft periodontal tissues during administration of bacterial lipopolysaccharide (LPS) and water avoidance stress (WAS) modeling. Material and methods. The experiment was performed on 24 rats. The animals were divided into 4 groups: control, WAS, animals injected intraperitoneally with 0.4 μg/kg of bacterial LPS of Salmonella typhi, WAS+LPS. Results. Water avoidance stress led to decrease of inducible NO-synthase (iNOS) activity in salivary glands by 1.63 times, but decreased arginase activity by 1.15 times, superoxide production increased by 1.53 times, catalase activity decreased by 1.2 times, and malonic dialdehyde (MDA) increased by 1.19 times compared to the control. Lipopolysaccharide led to increase of constitutive NO-synthases (cNOS) activity in salivary glands by 1.48 times, but decreased arginase activity by 6.15 times, catalase activity increased by 2.6 times and superoxide dismutase activity decreased by 2.74 times, and MDA increased by 6.84 times compared to the control. Water avoidance stress + LPS in salivary glands led to decrease of cNOS and arginase activity by 1.09 and 1.19 times, respectively, superoxide production increased by 1.88 times, catalase and superoxide dismutase activity decreased by 1.06 times and 1.34 times, respectively, and MDA increased by 2.44 times compared to the control. Water avoidance stress led to increase of iNOS activity in periodontium by 1.44 times and arginase activity decreased by 1.37 times, superoxide production increased 1.32 times, catalase activity and superoxide dismutase activities decreased by 1.27 times and by 1.53 times, respectively, and MDA increased by 1.31 times compared to the control. Lipopolysaccharide led to increase of iNOS activity in the periodontium by 3.88 times, arginase activity decreased by 2.69 times, superoxide production increased 1.64 times, catalase activity increased by 4.32 times, and MDA increased by 4.51 times compared to the control. Water avoidance stress + LPS in periodontium led to increase of iNOS and cNOS activities by 1.95 times and 1.53, respectively, arginase activity decreased by 1.39 times, superoxide production increased 1.66 times, catalase activity increased by 1.11 times, and MDA increased by 1.53 times compared to the control. Conclusion. The combination of LPS and WAS leads to changes in NO production and oxidative stress in salivary glands and the periodontium.

    Opis:
    Arrays of ultrasonic transducers used in medical diagnosis for safe and non-invasive visualization of the inside of a human body usually consist of many elementary piezoceramic transducers. In such an electromechanical construction of the array, while activating individual transducers, creation of crosstalk can be observed in the form of propagation of electric voltage and mechanical vibration on neighboring elements, which leads to distortion of the generated acoustical field, and in consequence reduces the quality of reconstructed medical images. Complexity of the problem rises rapidly in the case of arrays forming ultrasonic beams. In this paper, authors developed a numerical amplitude-phase model of multipath propagation of ultrasonic pulses generated in a soft tissue-like medium by such arrays. The model allowed simulation of acoustic field distributions, and to examine the influence of beam focusing in transmission mode on these distributions, taking into account electrical and mechanical crosstalk.

    Opis:
    The objective of the paper was to describe the impact of freeze-drying conditions on hardness of lyophilizates obtained based on soft fruit pomace. Raspberry, cherry, and grape pomace from the pressing process carried out with a low-speed rotary press constituted a research material. Immediately after the pressing process, pomaces were placed in forms, frozen, and after freezing they were freeze-dried in the pressure of 20, 42, 63, 85 and 110 Pa. The obtained lyophilizates were subjected to the measurement of hardness with the use of texture meter equipped with a penetrometer in the form of a cone with a vertical angle of 30°. The increase of pressure during freeze-drying of samples was accompanied by the increase of hardness of the obtained lyophilizates, which may affect the energy consumption of the grinding process and the nature of rehydration of the final product. Moreover, the water content of raw material, pomaces, and lyophilizates was determined. The obtained results of measurements were subjected to a statistical analysis which showed that the pressure of freeze-drying significantly diversifies the hardness of the obtained lyophilizates.
    Celem pracy było scharakteryzowanie wpływu warunków liofilizacji na twardość liofilizatów uzyskanych na bazie wytłoków z owoców miękkich. Materiał badawczy stanowiły wytłoki z malin, wiśni i winogron, uzyskane po procesie tłoczenia z wykorzystaniem prasy wolnoobrotowej. Bezpośrednio po procesie tłoczenia wytłoki umieszczano w formach, zamrażano, a po zamrożeniu liofilizowano w ciśnieniu 20, 42, 63, 85 i 110 Pa. Uzyskane liofilizaty poddano pomiarom twardości z wykorzystaniem teksturometru zaopatrzonego w penetrometr w postaci stożka o kącie wierzchołkowym 30°. Wzrostowi ciśnienia podczas liofilizacji prób towarzyszył wzrost twardości uzyskanych liofilizatów, co może mieć wpływ na energochłonność procesów rozdrabniania i charakter rehydracji produktu końcowego. Dokonano również oznaczenia wilgotności surowca, wytłoków i liofilizatów. Uzyskane wyniki pomiarów poddano analizie statystycznej, która wykazała, że ciśnienie liofilizacji w sposób istotny różnicuje twardość uzyskanych liofilizatów.

    EUV
    Opis:
    An Nd:YAG pulsed laser was employed to irradiate a nitrogen gas-puff target. The interaction gives rise to the emission of soft X-ray (SXR) radiation in the ‘water window’ spectral range (λ = 2.3÷4.4 nm). This source was already successfully employed to perform the SXR microscopy. In this work, a Silicon Carbide (SiC) detector was used to characterize the nitrogen plasma emission in terms of gas-puff target parameters. The measurements show applicability of SiC detectors for SXR plasma characterization.
