    Opis:
    Heat transfer through curvilinear partitions differs, in mathematical terms, from transfer through flat ones. However, in practical calculations, an approximation is commonly used by estimating heat loss by analogy to flat partitions. There are no studies in the literature related to an exact quantitative analysis of heat loss through curvilinear partitions. The aim of the article is a comparative analysis of the computational heat loss determined for layered cylindrical and spherical partitions determined by the exact and the approximate methods. The percentage discrepancy of results was determined. Relevant computational examples were analysed. It was found that in most cases the above approximation does not lead to significant inaccuracies if the basis for calculating the heat transferring surface area is the mean radius of curvature of the partition.

    Opis:
    One of the important factors on which road safety depends is adequate visibility. This article analyses horizontal visibility within road intersections. The visibility condition depends on many factors, primarily on the geometric parameters of road elements and the location of buildings, fences, vegetation etc., neighboring the road. The aim of the research presented in the study was to determine the current condition of horizontal visibility, on the example of twenty two intersections located mostly in built-up rural area along a provincial road near Czestochowa. The research was carried out by two methods (the analysis of satellite photographs and the visual method) and the obtained results were compared. The assessment of the security level was based on applicable regulations and technical guidelines. It was found that the results of the visibility assessment based only on the analysis of maps and satellite photographs are in many cases overestimated, due to the fact that many small elements not visible in the photographs are not taken into account and the occurrence of convex vertical road arches within the field of visibility. However, the main reason for the insufficient visibility at the many intersections is the fact that the geometrical parameters of roads and their surroundings were shaped in the past when the traffic conditions were completely different. It was also noted that road managers perceive this problem and take measures to increase safety within road intersections.

    Opis:
    Asbestos-cement waste from roof coverings and facades are classified as hazardous materials and should be successively removed from buildings. The current management of these wastes is limited to their controlled depositing in landfills, which does not ultimately solve the problem of their impact on the environment in the future. The article presents the current state of disposal of asbestos in Poland, with particular emphasis on the Silesian Voivodeship. The literature reports on the methods of neutralizing this type of waste and the possibility of their recycling were analyzed. It was found that the most popular way of recycling asbestos waste is thermal treatment, and the least effective - chemical treatment. Unfortunately, legal barriers prevent the spread of these solutions in the country in practice, despite the fact that safe methods of recycling asbestos-cement products are known.

    Opis:
    In recent years, numerous measures to modernize local roads in rural areas have been undertaken. Unfortunately, during renovations, especially at the poviat and commune level, errors are often made as a consequence of irregularities arising at the design stage. The article presents an assessment of the quality of local road renovations carried out in the last fifteen years, in the context of maintaining operational parameters over time, using a visual method based on the term “risk”. The research was carried out for twenty-six sections of roads that were renovated or rebuilt in the Kłobuck and Częstochowa poviats. The categories of the most common errors were identified and actions were proposed to correct them and prevent new ones. Among the negative trends, the improper placement of road technical devices and the lack of appropriate marking of integral areas were distinguished. It was found that a positive aspect in the aspect of traffic safety, recently, is the widespread use of modern road marking systems and road signs, as well as greater care for proper maintenance of drainage devices. The use of modern solutions during the modernization of roads, despite co-financing from the Government Fund, is still limited by the financial deficit of local governments.

    Opis:
    In the last few decades there have been significant changes in single-family housing in rural areas. More and more new buildings are being built, many are being renovated or thermomodernized. This activity generates a number of waste that, if not managed properly, can have a negative impact on the natural environment. This article analyses ways of waste management generated during the erection of new buildings, renovations and reconstruction. The aim of the research presented in the study was to identify trends in the manner of construction waste management in the last thirty years in rural areas of the Czestochowa district. The substantive basis for the research were CAWI (Computer Assisted Web Interview) surveys carried out among investors and contractors of construction works in the analysed area. On their basis, indicators illustrating changes in the manner of management individual types of waste were estimated. It was found that positive changes occurred in this area during the analysed period. Primarily, the scale of activities having a clearly negative impact on the environment and the safety of life of residents decreased significantly. Processes such as uncontrolled burning or burying waste in the ground have been reduced from over 40% to around 13.5%. The reason for these positive trends is primarily the increasing ecological awareness of rural residents, high fines for the illegal removal of waste, as well as in the case of waste other than construction, the obligation to have waste containers. Currently, positive environmental activities such as selective waste collection and transfer to specialized companies increased from around 2.5% to over 50%.

    Opis:
    The layout of rural buildings has been shaped over centuries as most existing towns were founded several hundred years ago with the main reason for establishing a village in a given place being natural factors such as access to resources. Over the centuries, some characteristic building layouts have emerged. The aim of the research presented in the article was to determine the degree of impact of natural factors on the process of establishing a village and to identify contemporary factors influencing the development of the historical layout of rural buildings. The research was carried out using the example of a rural commune neighboring Częstochowa. All the towns in the exemplary rural commune were analysed historically. The results are presented in the form of numerical indicators showing the influence of individual factors on the settlement of the village. Then, using the example of four representative settlements for different types of buildings, the historical and current layout was compared. It was found that the original layout of buildings has been preserved as a general outline, and current development depends mainly on economic factors and the attractiveness of the area, illustrated with appropriate examples.

    Opis:
    W artykule przedstawiono studium przypadku ilustrujące typowe problemy użytkowników starszych domów jednorodzinnych w aspekcie pracy tradycyjnej wentylacji grawitacyjnej. Na podstawie przeprowadzonych badań stwierdzono, że przyczyną powstawania tzw. wstecznych ciągów, oprócz czynników pogodowych, może być wpływ urządzeń mechanicznych wymuszających ciąg w przewodach wentylacyjnych (okap kuchenny) lub dymowych (dmuchawa kotła c.o.). Zwrócono również uwagę na potrzebę częstych przeglądów skuteczności wentylacji, aby wyeliminować pewne prozaiczne powody jej nieskuteczności.
    The article presents a case study illustrating typical problems of users of older single-family houses in the aspect of traditional gravitational ventilation. Based on the conducted research, it was found that the cause of the so-called backdrafts, apart from weather factors, may be caused by the influence of mechanical devices forcing draft in ventilation ducts (kitchen hood) or smoke ducts (central heating boiler blower). Attention was also drawn to the need for frequent reviews of the effectiveness of ventilation to eliminate some prosaic reasons for its ineffectiveness.
