Opis:
Vehicles are equipped with more and more devices to improve the comfort of traveling. They are usually powered by electricity generated by the engine, which translates into an increase in its loads and, as a consequence, fuel consumption and emission. However, there is no information about the possible increase in the amount of other harmful components contained in the exhaust gases. Often this result is inadequate to that obtained during the operation of the vehicle, where the obtained fuel consumption is higher. As part of this article, tests were carried out in real hybrid vehicle traffic conditions on the same test route using an analyzer from the PEMS (Portable Emission Measurement System) ¬ SEMTECH DS Sensors Inc. The analysis of gaseous components of exhaust gases together with the exhaust mass flow probe and the GPS system made it possible to calculate the pollutant emission. On this basis, the actual mileage fuel consumption of the tested vehicle was calculated using the road emission of carbon-containing compounds (carbon balance method).

Opis:
The use of comfort systems, the number of which in vehicles is constantly increasing, has a direct impact on fuel consumption and engine load. As part of the article, the vehicle's drive in real operating conditions was analyzed in terms of the emission of toxic compounds. The tests were carried out without and with the systems turned on, using the PEMS apparatus, where road emissions of carbon dioxide, carbon monoxide, hydrocarbons, nitrogen oxides and solid particles were measured in terms of mass, number and size distribution of diameters. The track was driven four times with different setting of the powertrain of examined car. The differences concerned the number of comfort systems in the vehicle and the mode of operation of the combustion engine.

Abstract In this article Authors present the continuation of the calculations for theoretical ACC engine cycle, considering additionally “VCR function” – changeable compression level. For this purpose the self-acting volume change, realized by ACC system, was used. The ACC system was adjusted appropriately to control the compression level. The analysis is based on three cases, representing delayed, premature and optimal reaction of ACC system. Reactions are presented in form of plots with indicated pressure in the combustion chamber. As the result of the conducted analysis and interpretation of obtained graphs, the calculation approach of compression ratio for ACC presented in previous article is being challenged. For the optimal reaction of ACC system, the theoretical operation schematics are devised and presented in the key points of the work. Based on the schematics, the values of theoretical efficiency were calculated for different cycles of theoretical ACC engine, in which regulation of compression ratio takes place. Moreover, the presented analysis includes graphs with optimal courses of indicated pressure for significantly different work parameters of ACC engine, showing its regulation possibilities. Also the time scaled graphs (with millisecond as basic time unit) are presented to show the possibilities of dynamic ACC systems, which are comparable with the combustion time (from 3 to 0,5 ms). In this paper the general discussion is started about the compression ratio in more complex kinematic systems including ACC.

Opis:
The COVID-19 pandemic affected the elderly in a special way. On the one hand, it contributed to the increase in health deficits and those related to social isolation. On the other hand, it also had a significant impact on the level and methods of support provided to seniors. The pandemic situation turned out to be a particular challenge for local governments and non-governmental organisations operating in various areas of senior policy. The general aim of the article was to analyse the state’s initiatives aimed at counteracting the effects of the COVID-19 pandemic addressed to seniors and examples of activities of the local government and the civil sector cooperating with it for the benefit of this group of people. In turn, the specific objective was to identify and understand the greatest difficulties that seniors had during the pandemic and the role played by the non-governmental organisation (both during the pandemic and as an entity of potential support in the future, which was particularly interesting given the European Union promoting services provided in the local environment). In connection with the specific objective, qualitative research was carried out using the in-depth interview method. The interviews were based on scripts that concerned four areas: problems and experiences of the elderly during the pandemic, help and support, communication, health, and well-being.

Opis:
Among many demographic changes, one of the most evident now is the aging of the population, the consequences of which are increasingly leaving a mark on the directions of social policy. In connection with the aging of the population and positive aspects, manifestations of ageism, based on stereotypes and negative attitudes toward older people, are also more and more noticeable. Sometimes, these are discriminatory practices against older people encountered in the health sector, the labor market, public offices, and others. The research presented in the article aimed to identify age discrimination and its manifestations among older people. The purposive sampling technique was used to choose the research sample – the assumption was to examine active older people related to a large city who get involved and participate in various activities and projects carried out for them by nongovernmental organizations. The method of a diagnostic survey with a questionnaire, which included both closed and open-ended questions, was used in the research. The research was intended to help answer the following questions: do older people notice age discrimination, and have they experienced worse treatment because of their age? How many of the surveyed seniors experienced worse treatment and what forms (most often) did it take, and where did it happen?

Opis:
Europe is turning toward the idea of social cohesion, which can be considered an updated version of solidarity and was constructed in direct response to the problem of social exclusion. Social cohesion implies a thorough reconstruction (but not a deconstruction) of Europe’s welfare states, or in other words – as some prefer to say – the European social model. In the European Union, in the broadly understood social sphere, the core of the social cohesion policy is “active social policy”. Programmes that are organised in the framework of “active social policy” are designed to stimulate beneficiaries, provide specified goods and services, and increase the level of participation in social life and economic exchange. Undoubtedly, one of the fundamental measures of social cohesion is the strength and character of local social ties. Contemporary social policy is in large part decentralised and thus based on the principle of state subsidiarity that is oriented toward strengthening social cohesion “at the bottom level”. In the transition from the welfare state to welfare society, the social economy takes on a particular meaning. The social economy as a set of tools that increase the participation of people marginalized by the labour market and members of neglected local communities in both economic activity and social life. The social economy is a space for realising programmes that promote active social policy. The social economy is a social movement that should lead to a new vision for Poland’s devolpment is also a way of involving the third sector in Poland’s economie development. Social economy has been accepted as an innovative and practical solution to the problem unemployment into the European Union, gives a chance to change the status quo, being one of the most effective ways to activate the long-term unemployed. Social economy institutions offer creative approaches to maintaining financial self-sufficency while fulfing a cleary definined social mission. In Poland in recent years interest in the social economy has clearly increased. Social enterprise initiatives have been launched by numerous non-governmental organisations. Information about many newly established social enterprises, especially social cooperatives, have appeared in the media. This new wave of interest in the social economy is linked to the perception of both policy-makers and public opinion regarding the necessity for reorienting social policy toward activating forms of social support, in place of protective activities. One element of the debate about the new wave of the social economy that is taking place in Poland is a focus on new members in the sector, such as: social cooperatives, not-for-profit companies and non-governmental organisations.

Opis:
W ostatnich latach zasadniczej zmianie uległa struktura ludności pod względem wieku. W najbliższych dekadach należy oczekiwać nie tylko kurczenia się zasobów pracy, ale i ich ciągłego starzenia się. W wielu dokumentach rangi państwowej podkreśla się, że aktywne starzenie się jest jedyną szansą sprostania wyzwaniom, jakie niosą zmiany demograficzne, warunkiem koniecznym przyszłego dobrobytu i spójności społecznej. W tym kontekście wskazuje się na konieczność oddziaływania na jak najdłuższe zachowanie społecznej produktywności jednostki (działalność społeczna, zawodowa), a w odniesieniu do osób na przedpolu starości wskazuje na potrzebę aktywności zawodowej. W tej optyce starzenie się populacji nie musi nieść ze sobą tylko zagrożeń, ale może stanowić szansę na rozwój gospodarczy (usługi, towary, miejsca pracy). Jednak warunkiem dalszej aktywności zawodowej, społecznej i gospodarczej osób na przedpolu starzenia się jest dobry stan zdrowia i jak największy poziom ich samodzielności. W tej optyce zwiększa się rola zarządzania wiekiem, które dotyczy najczęściej osób w wieku powyżej 50 lat i odnosi się do przygotowania do dłuższego cyklu życia zawodowego. Zarządzanie wiekiem jest częścią polityki senioralnej, która koncentruje się na działaniach mających zwiększyć wydajność pracy osób starszych, a w konsekwencji ich zatrudnialność. Wachlarz działań podejmowanych w celu stworzenia środowiska pracy sprzyjającego pracownikom w różnym wieku, umożliwiającego wykorzystanie ich możliwości i zaspokojenie potrzeb okazuje się być stosunkowo szeroki.
In connection with the demographic changes taking place in recent decades, one of the key issues are the appropriate management of the potential of the growing number of elderly people and undertaking action to mitigate the economic and social impact of aging of the population. The involvement of older workers in the labor market and the maintenance of good health, activity and independence are the best ways to alleviate the problems resulting from aging of societies and to preserve intergenerational solidarity. The aim of the article is to analyze the demographic situation in Poland in the context of the potential of labor resources and to present the concepts and instruments of age management. The research hypothesis oscillates around the claim that the application of age management strategies makes it possible to make the best use of the potential of all employees in a company, regardless of their age. If restructuring of positions and tasks can increase productivity of employees and improve the use of human capital, dissemination of age management systems in companies is one of the most desirable actions minimizing negative trends in the labor market, both in the social and economic sphere.

Opis:
Heavy, black manganese pebbles have been found in the clastic sediments of the Hochschartehöhlensystem (the Northern Calcareous Alps). Six selected pebbles were subjected to X-ray diffraction, optical microscopy and optical and electron microscopy analysis. The results reveal that the main component of the pebbles is manganese silicate, braunite, Mn2+Mn3+6(SiO4)O8. Braunite is a mineral formed at elevated temperatures, mainly through hydrothermal, metamorphic or diagenetic processes. This means that the manganese pebbles were formed outside the caves. However, manganese rock was not found in situ on the surface of the Hoher Göll Massif. This probably indicates that their origin is from eroded parts of Mesozoic rocks. The first studies of pebbles and their mineralogy, by analogy with contemporary marine sediments, indicate that their genesis is related to spreading zones and accompanies hydrothermal vents. The analysed material highlights two important issues: (1) the manganese pebbles are significant arguments for the occurrence of hydrothermal vents in the Northern Calcareous Alps; and (2) the importance of cave sediments studies, which provide relevant evidence for palaeogeographic reconstruction.

Opis:
This paper presents calculations of the theoretical cycle of engines with an active combustion chamber depending on energy delivery and dissipation. In the case of ACC engines, a different calculation approach is required to account for the possibility of additional volume change, independent of the piston-crank system. The introduction presents a schematic diagram of volume change, accomplished by two independent piston-crank systems and an active combustion chamber, as proposed by the authors. Moreover, the diagram, which is the basis for analysis in this paper, illustrates characteristic points of the cycle. In existing theoretical cycles of combustion, this issue does not present any difficulties, since the solution is exact and based on known equations. In the case of theoretical ACC engines, however, the situation is different, since this engine can perform not only in typical cycles, but also in new ones. To explain the challenges of these new cycles, authors present a few of the most probable calculation variants, taking into account the new kinematic capabilities of ACC engines. Each comment justifying the choice of a certain calculation variant is illustrated with a theoretical cycle figure and closest approximation of induced pressure course of the ACC engine. At the same time, however, the authors show that this problem can have many interpretations. It has been concluded that the solution depends on the assumptions made about the active combustion chamber, namely its principle of operation.
