Opis:
Subjective cognitive complaints (SCCs) are defined as belief of the decline of a cognitive condition compared with an earlier period of functioning. Many studies have shown the relationship between SCCs with objective neuropsychological results as well its dependency on psychological characteristics. Considering the complex nature of SCCs, this study tested the relationship between SCCs reported in the attention domain with the results obtained in neuropsychological attention tasks, as well as with psychological cha racteristics and among complaints reported in various domains of functioning. Sixty participants over 60 years of age took part in the study. Subjects were tested for the intensity of SCCs in everyday func tioning, psychological characteristics (mood; anxiety, state and trait; and personality traits) and various aspects of attention domain (switching, divided, and focus). The SCC intensity reported in various areas of functioning was associated with each other as well as with psychological characteristics (personality traits, anxiety, and mood/depression). There were no significant relations between the SCC intensity reported in the attention domain and the outcomes obtained in neuropsychological attention tasks. Our results showed that the intensity of SCCs may be a result of subjects’ psychological characteristics and that the tendency to report complaints in various spheres of functioning simultaneously may be observed. It seems to be important to consider that SCCs are related to several psychological factors when it is included in a cognitive diagnosis and treated as a direct indicator of a cognitive condition.

Opis:
Przeprowadzono analizę metod adsorpcyjnych i membranowych pod kątem zatężania metanu w powietrzu wentylacyjnym kopalń (VAM). Stwierdzono, że możliwe jest zwiększenie stężenia VAM z 0,2-0,3% obj. do co najmniej 1% obj. przy wykorzystaniu obu technik separacyjnych, co powinno ułatwić jego utylizację w reaktorach rewersyjnych lub silnikach na paliwo ubogie.
Technologies for thermal utilization of ventilation air methane (VAM) require stabilization and/or increasing its concentration. This paper summarizes the results of research conducted at the IICh PAS in the area of adsorption and membrane processes for VAM enrichment. First of all adsorbents and membrane materials were selected and investigated for such processes. They were assessed in terms of CH4/N2 selectivity, as defined by Eqs 1 and 2, as well as adsorption capacity (adsorbents) and permeability (membranes). The properties of activated carbons and ZMS 5A investigated were presented in Table 1 and Fig. 1. In the case of membranes polyimide membranes, used in commercial UMS-A5 and CO-C05 UBE modules, as well as the Matrimid 5218/CMS composite membrane, were selected for membrane VAM enrichment process. The pressure swing adsorption process in two-bed (Fig. 2) and four-bed (Fig. 4) installations for VAM enrichment was also investigated. The process performance was presented in Fig. 3 and Figs 5-6, respectively. It has been found that in the case of the four-bed process with activated carbon G2X7/12 Takeda VAM can be enriched from 0.2 to over 1.2 vol.% with a recovery of at least 80%. The results of membrane VAM enrichment processes were summarized in Table 2. It was found that in the case of commercially available UBE modules UMS-A5 and CO-C05 the concentration of methane in VAM can be increased from 0.3 to 0.43 vol.% with moderate CH4 recovery (50-60%). Higher enrichment (up to 1,8 vol.% in a three-stage system) can be obtained in the case of the hybrid Matrimid 5218/CMS. For an assessment of the energy efficiency of the PSA and membrane enrichment processes two factors were defined: the unit power necessary to generate the pressure ratio pW/pN in the separation process (Eq. 3) and the unit heat output of the ventilation air (Eq. 4). These factors were presented in Fig. 7 along with unit thermal power of the enriched gas for the membrane (triangles) and adsorption (diamonds) VAM enrichment processes. It was found that regardless of the separation method and process parameters, the potential energy gain from the utilization of enriched VAM is much lower than the energy expenditure related to the implementation of the enrichment process, which is primarily due to the low unit thermal power of the ventilation air.

Opis:
Decarbonization, minimizing greenhouse gas emissions, circular economy and the waste-to-energy trend lead to increased demand for gas and green energy. The European Biogas Association shows that biomethane gas can cover 30-40% of EU gas demand by 2050. There is a steady increase in the number of biomethane installations in Europe. The application of membrane processes to biogas upgrading has been intensively researched. It is practically used in large installations with several hundred m3/ h of biogas, operating at pressures higher than 1 MPa [3-5].The problem arises when dealing with small farms, such as in Poland. Despite the estimated energy potential of the Polish agro-food sector for biogas production being over 7.8 bcm per year, there is a lack of small-scale biogas upgrading technologies suitable to Polish conditions. A good energy efficiency and overall profitability of the investment may be more difficult to achieve in this case. The proper design of a membrane separation process should be based on a thorough knowledge of the membrane characteristics, i.e. the permeability coefficients and selectivity on it, under conditions as close as possible to the actual operating conditions of the plant [6]. The aim of the work was to develop a methodology leading to a non-invasive estimation of the actual values of the permeability coefficients of the main biogas components CH4 and CO2. The laboratory tests were carried out on two kinds of flat polymer membranes (PPO 70 and AE 55) prepared by the Center for Polymer and Carbon Materials of the Polish Academy of Sciences in Zabrze. Both membranes had an active surface of 58 cm2 and a thickness of 85 μm. The pure gases CH4, CO2 and mixtures CO2/CH4 were examined separately. Permeation studies of pure gases were carried out at a feed gas flow rate of approximately 40 ml/min, a transmembrane pressure drop in the range of 1.7-7.5 bar (abs) at temperatures 19-21°C. However, the tests on the separation process of CO2/CH4 mixtures were carried out for feed gas flow rates of 60, 100, and 130 ml/min, with a constant transmembrane pressure drop of approximately 7 bar (abs), at a temperature of 20-22°C where methane concentration in carbon dioxide was 40, 50 and 60 vol.%. It was found that carbon dioxide was a component that permeated more quickly through both of the membranes. Moreover, it was observed that in each case the permeability coefficients are not constant, but change with the change in the feed gas pressure. The data from experimental research allowed to determine permeability coefficients and ideal CO2/CH4 separation factors which were respectively: PCO2 = 150 barrer PCH4 = 61 barrer, α*CO2/CH4 = 2.46 for the PPO 70 membrane, and PCO2 = 162.6 barrer, PCH4 = 25.8 barrer and α*CO2/CH4 = 6.3 in case of the AE 55 membrane.
Wyznaczono współczynniki przepuszczalności składników biogazu (CH4 i CO2) dla dwóch membran, wykonanych odpowiednio z tlenku polifenylu (PPO 70) oraz bezwodnika diftalowego i diaminy AE 55). Badania prowadzono dla czystych gazów i ich mieszanin w płaskich membranach polimerowych. Stwierdzono, że dla obu membran lepiej permeującym gazem jest CO2. Współczynnik permeacji tego gazu wyniósł 150 barrerów dla PPO 70 oraz 162,6 barrera dla AE 55, a idealny współczynnik rozdziału (α*CO2/CH4), odpowiednio 2,46 i 6,3.

Opis:
Objective: to evaluate knowledge about phytoestrogens among Polish menopausal women, and to assess their applicability and safety. Methods: The study included 300 women from the Wielkopolska Region, aged 40-60 years. The questionnaire was designed especially for the study. Crosstabulation tables and Perason’s chi-squared test was used for the statistical analysis. Results: 147 respondents continued to menstruate. Hormone Replacement Therapy was used by 69 subjects; 114 respondents, used phytoestrogens. The place of inhabitance influenced the reasons for not using phytoestrogens. Media, healthcare providers and personnel were the main source of information about phytoestrogens. Most of respondents perceived phytoestrogens as substances displaying a beneficial effect on health. 69% of the subjects reported positive effects of non-hormonal preparations for the relief of climacteric symptoms, mainly reduction in hot flushes and alleviation of joint pain. Conclusions: Our results support the postulate of efficacy and safety of phytoestrogen use to relieve climacteric symptoms. Both education and place of inhabitance appear to affect the opinions of the affected females about phytoestrogen use during menopause.

Opis:
The aim of the paper was to identify different levels of social sustainability in all FADN European regions. The study is based on the Sustainable Value (SV) method, which is value-oriented, measured as the sustainability of agriculture at the micro-economic level (e.g. agricultural farm). To be able to compare farms among themselves, an RTC was calculated. The FADN database for the years 2004-2015 was used in the article, analyzing farms in all regions. It identifies regions, where farms made a positive contribution to social sustainability and those, compared to the EU average, which need mainly institutional support in order to bridge the gap with the best.

Opis:
Progeny from 19 family lines of silver fir (Abies alba Mill.) from a small, native and isolated population from the Tisovik Reserve (Belarusian part of Białowieża Primeval Forest) growing in an experimental plot near Hajnówka (Polish part of Białowieża Primeval Forest) were analysed in terms of 4 nuclear microsatellite DNA loci and 9 isozyme systems with 14 loci. The aim of this study was to determine the genetic variation within and between progeny lines. Analysis of isozyme loci showed that all progeny lines, except the progeny lines T6 and T16, were characterised by an excess of heterozygotes and 20% of the detected variation occurred between progeny. Progeny formed two groups. Microsatellite loci showed that 6 progeny lines demonstrated an excess of heterozygotes and 12 an excess of homozygotes. On an average, the population was in the Hardy–Weinberg equilibrium. Analysis of molecular variance (ANOVA) showed that 14% of the detected variation occurred between offspring and the remaining 86% within progeny lines. The most distinct progeny line was T1, where the highest number of alleles per locus was detected. Generally, progeny of Tisovik is characterised by high level of differentiation as the offspring of isolated population that have limited number of individuals to crossing (only 20). In some progeny line, the private alleles that are detected may be the result of pollination from Polish part of Białowieża Forest where in 1920s and 1930s of XX century had planted the seedling of silver fir of unknown origin. The substructuring of population is observed, and the detected deficiency of heterozygotes may be ostensible as a result of the Wahlund effect. Such pattern of genetic structure could also be an effect of harsh environmental conditions exerting selection pressure and modifying the genetic composition of this population.
