Opis:
The aim of the article is to outline the theoretical framework for studying the relationship between the quality of the city’s recreational offering and the physical activity of its inhabitants. The study was based on a review of the literature and was supplemented with data from a pilot questionnaire survey. The pilot survey was conducted in 2016 and involved 180 inhabitants of Bielsko-Biała. Responses were collected during direct interviews based on the survey questionnaire consisting of two parts: International Physical Activity Questionnaire (short version) and recreational offering assessment questionnaire proposed by authors. The literature review revealed gaps in research and publications addressing the relationship between the quality of the city’s recreational product and the level of physical activity of its inhabitants, and results of previous studies vary depending on their location (which was also confirmed by the pilot survey). According to the authors’ pilot survey, the respondents preferred outdoor forms of physical activity (Nordic walking and fast walks). The majority of respondents can be classified as sufficiently active. No statistically significant findings were found between respondents’ assessment of the service staff or the recreational infrastructure and the level of physical activity reported by inhabitants of Bielsko-Biała who participated in the survey. The innovative character of the work consists in developing and testing during the pilot survey a new theoretical framework for researching relationships between the quality of the city’s recreational offering and the level of physical activity of its inhabitants. The authors propose extending the existing approaches involving mainly the assessment of recreational assets by including marketing, staff-related and organizational aspects. This calls for interdisciplinary research.

Opis:
In this paper, the research progress of ammonium bisulfate (ABS) volatilization in coal-fired power plants the SCR denitrification process was reviewed. Combination with self-made experiments, SEM, flue gas analyzer and TG-DTG curves of ABS and ion chromatography. The volatilization and condensation characteristics of ABS were investigated carefully. Results show that as the temperature increased by 50 °C, the ABS/AS volatilization rate increased by an order of magnitude. The decomposition process of ABS should have a two-step reaction. The reaction in the initial volatilization stage is ABS dehydration turned into (NH4)2S2O7. The reaction in the rapid volatilization stage is (NH4)2S2O7 decomposed into NH3, N2, SO2 and H2O. There is an inter-section in the reac-tion temperature range (especially 300 °C) between the two-step reaction. This research provides an experimental basis for temperature control of ABS to avoid air pre-heater fouling.

Opis:
Voltage source converter-based multi-terminal high-voltage direct current (VSCMTDC) transmission system can realize a multi-point power supply, multi-drop power receiving, and mutual coordination between the converter stations to ensure the reliability of the transmission. Based on the PSCAD/EMTDC platform, a five-terminal DC transmission system model is established. According to the fast power regulation capability and overload capacity of theVSC-MTDC power transmission system, an analysis of additional emergency power support for a transmission system under large disturbance conditions was carried out. A new control strategy for emergency power support that introduces its basic principle is proposed in this paper. It uses the short-term overload capability of the DC system. By changing the power reserve of the converter station and the electrical distance between the converter stations, the influence of the power reserve and the electrical distance on the emergency power supply guarantee is analyzed the stability of the system is improved, thereby improving the sudden change of power caused by voltage fluctuations, and the feasibility of the control module is verified by PSCAD simulation. The simulation results show that when the system power supply suddenly changes, the converter stations at a short distance and large power reserve has a better effect on emergency power supply protection. A comparative study of the active power support of a single converter station and multiple converter stations is carried out. The research results show that the use of emergency power support in the DC transmission system has a good effect on maintaining the stability of the inter-connection system and the reliability of the power supply.

Opis:
Despite strong development in Vietnam’s major cities, buses only contribute to city traffic. Bus services in Vietnamese towns do not yet meet passengers’ current needs and are not popular with passengers, especially in terms of time and convenience. This article analyzes the factors affecting urban people’s intention to use buses in Vietnam and, on that basis, makes recommendations to the authorities in cities to enhance the attractiveness of bus usage. Twenty-seven factors have been identified as affecting the need to travel by bus. The survey results show that there are still many barriers to attracting passengers using bus services in urban metropolitan areas. Therefore, urban governments in Vietnam need to adjust the current bus route network to suit the needs of the people, especially students, to increase its coverage.

Opis:
Wykorzystując wyniki studiów literatury i prac własnych, zaproponowano wskaźnik śmiertelności demograficznejw wypadkach drogowych WSD jako miarę poziomu bezpieczeństwa ruchu drogowego. Zgromadzone zbiory dostępnych danych pozwoliły na zidentyfikowanie grupy najbardziej istotnych czynników wpływających na bezpieczeństwo ruchu drogowego na obszarze kraju. Opracowano model zmian tego wskaźnika WSD z wykorzystaniem funkcji potęgowo-wykładniczej uwzględniającej najbardziej istotne czynniki. Do budowy tej funkcji zastosowano kilkanaście zmiennych niezależnych reprezentujących charakterystyki przestrzenne, demograficzne, ekonomiczne, społeczne, motoryzacyjne, infrastrukturalne i transportowe analizowanych krajów, z których najbardziej istotnym okazał się poziom rozwoju społeczno-gospodarczego. Przedstawiona w artykule funkcja opisująca zmiany wskaźnika WSD może być wykorzystana do wyjaśniania aktualnego stanu bezpieczeństwa ruchu drogowego w poszczególnych krajach oraz jego prognoz.
Based on a study of literature and own work the road accident demographic mortality rate (WSD) was developed as a measure of road safety. Sets of available data helped to identify groups of the most critical factors which affect a country's level of road safety. A model was developed to show how the WSD rate changes using the power-exponential function which includes the most relevant factors. The function is built from morę than ten independent variables representing spatial, demographic, economic, social, motorization, infrastructural and transport characteristics of the countries under analysis. It was established that the level of human-economic development is the most critical factor. The article presents a function which describes how the WSD rate changes. It can be used to explain a country's current level of road safety and its forecasts.
