Abstract

This article contains information concerning of the analysis the possibility of defining refinery qualities of the slag based thermophysical and thermodynamical data. The paper presents a model of slag refining processes and a method of determining the reduction capability of slag solutions. Slag was analysed with the use of the DTA methods for the brass melting conductions. The study of computer program including the satisfactory number of data there are used in to the design a modern device rotating head used for gas-slag refining. It was achieved that the refining gas and fluxes were distributed ever by the rotating head. High effectiveness of the gas-slag refining processes was proved for the brass.

Abstract

The article describes the optimization of the melting brass. Brasses, as one of the most popular alloys of copper, deserve special attention in the context of the processes of melting, which in turn would provide not only products of better quality, but also reduce the cost of their production or refining. For this purpose, several studies carried out deriatographic (DTA) and thermogravimetric (TG) using derivatograph. The results were confronted with the program SLAG - PROP used to evaluate the physicochemical properties of the coatings extraction. Based on the survey and analysis of the program can identify the most favorable physico - chemical properties, which should be carried out treatments. This allows for slag mixtures referred configurations oxide matrix containing specific stimulators of the reaction. Conducted empirical studies indicate a convergence of the areas proposed by the application. It should also be noted that the program also indicates additional areas in which to carry out these processes would get even better, to optimize the melting process, the results.

Abstract

Good practices in the creation of the Commune Revitalization Program – cooperation between the University of Adam Mickiewicz and the City of Kalisz, The entry of the Revitalization Act on November 18, 2015 enabled municipalities to efficiently plan and conduct the process of moving degraded areas out of the crisis. The Act introduced key regulations affecting the programming of revitalization in Poland. One of the most important instruments is the Municipal Revitalization Program. In order to be able to fully use the potential of this document, we should look for solutions that allow creating the most comprehensive solutions. One of the examples of such activities is cooperation between the university and the local government. Thanks to this combination of practical knowledge of officials with theoretical knowledge of academic experts, we can say that it is a project unique in the country. It is also unique due to the fact that spatial economy students who actively participated in the document creation process were included in the work. The aim of the work is to present the course of the cooperation process of the University of Adam Mickiewicz with the Office during the preparation of the Municipal Revitalization Program for the city of Kalisz and showing the role that the students included in the project played in this project

Abstract

The revitalization of brownfi elds and post-industrial facilities is a long-term and multistage process. In the first stage of revitalization, it is important to assess the material, emotional and utilitarian value of the preserved cultural heritage. On the example of a revitalization project that has been ongoing since 1996, the former areas of the Gdańsk Shipyard, where the remains of the Imperial Shipyard and Schichau Shipyard are located, the process of formulating the value of the preserved cultural material heritage has been presented. The impact of this process on the subsequent stages of the revitalization of the Young City in Gdańsk was also presented. Gdańsk Shipyard is the cradle of Solidarity, so the emotional value associated with the events accompanying the creation of the Solidarity movement was considered to be the dominant one. Only two objects were entered in the register of monuments; BHP Hall and Solidarity Square (Plac Solidarności). When the Local Development Plan has been passed many investments have begun by various investors without comprehensive integrated activities. The demolition of the preserved halls and the dismantling of shipyard equipment began. This caused that in 2015 the uniqueness of the survived post-industrial complex, qualifying it for inclusion in the World Heritage list, was appreciated. In 2018, the Provincial Pomeranian Monument’s Conservator began the procedure of entry of the preserved objects to the register of monuments. This resulted in the suspension of all investments that commenced legally in the area covered by the proceedings. Lack of proper assessment of the cultural value of material heritage at the stage of preparing the revitalization process led to the loss of part of this heritage and caused increase of the investment activities risk in this area.

Abstract

Experiences of subregional cities in programming of urban renewal. The aim of the article is to analyze and evaluate the experience of selected subregional cities in revitalization programming. At the beginning, the strategic policy of the state towards subregional centers was defined. The guidelines from the National Spatial Development Concept, the National Urban Policy and the Strategy for Responsible Development were pointed out. Then, examine in detail the activities carried out so far in 4 cities, which as a result of the administrative reform in 1999 lost the status of the provincial city, i.e. in Ciechanów, Legnica, Piła and Przemyśl. Current documents have been characterized, in particular, the specificity of areas covered by revitalization has been described. Next, the leading directions of transformations of these areas were presented, resulting from the adopted revitalization policy. This allowed for the formulation of certain generalizations about the specificity of the process of renewal of degraded areas in subregional centers in Poland.

Abstract

Dynamic development in children’s research has led to surprising discoveries about the learning and thinking patterns of fetuses, infants and young children. These studies have revolutionized not only our knowledge of children, but also our understanding of the nature of the human mind and brain. Moreover, within this context, it is believed that many areas of adulthood are the result of the experiences and changes that occur during the fetal period and in childhood. These experiences, therefore, are crucial for human development and what people achieve in the following stages of their lives. The results of the research on brain development during the fetal period and during childhood presented here, reveal a new perspective for understanding the essence and nature of the learning process. These studies also strongly suggest that the first two thousand days of a child’s life are critical in developing many basic human skills. Therefore, we must take great care of the quality of environment for a child’s development.

Abstract

The problem of optimally controlling a Wiener process until it leaves an interval (a; b) for the first time is considered in the case when the infinitesimal parameters of the process are random. When a = ��1, the exact optimal control is derived by solving the appropriate system of differential equations, whereas a very precise approximate solution in the form of a polynomial is obtained in the two-barrier case.

Abstract

Art. 52 sec. 1 of the Regeneration Act of 9 October 2015 allowed municipalities which, at the time of its entry into force, did not have a valid revitalization program, to carry out revitalization activities on the basis of a revitalization program other than the municipal revitalization program. The choice of procedure was left by the legislature of the municipality, assuming that at the initial stage of the implementation of the law, only the municipality should test its instrument, referring to the nature and scale of its needs. The ROP Managing Authority in Małopolska as the only one in the country introduced the requirement of developing municipal revitalization programs for all municipalities that did not have a current revitalization program at the time of the entry into force of the Act. Therefore, these municipalities, in order to benefi t from EU funding under ROP WM 2014-2020 for revitalization activities planned in the programs, were not able to rely on the derogation contained in art. 52 sec. 1 of the Act. Regardless of the size of the municipality and the nature of revitalization needs, they were compelled to develop a document complying with the statutory procedure, the fi rst stage being the delimitation of the degraded area and the revitalization area and confi rmation by the resolution of the municipality council. As a result Małopolskie Voivodeship has become Poland’s largest laboratory of methodology of delimitation of these areas and development of revitalization programs. The aim of the article is to present the diversity of applied methodological approaches to the delimitation of revitalization areas in Małopolskie Voivodeship and to describe the most noteworthy, as well as to indicate the most common errors in the designation of these areas.

Abstract

Both the landscape shaped and recognized as valuable, as well as the internally incoherent, low-value landscape are the basis on which the development and transformation of culture, social ties and ties with the place take place. Shaping the landscape is associated with among others, on identity, creativity and responsibility for the place. The social eff ects of building a valuable, attractive landscape, including the urban landscape, are determined by many activities, not only those related to building and functioning of the built environment. Communal revitalization programs emphasize the importance of the aesthetics of public places and undertake the eff ort to involve the local community in increasing the aesthetics of the neighborhood and semi-public spaces. However, landscape themes appear sporadically at the occasion of discussing the attractiveness of a place of residence and are intuitively intertwined with the issues of the quality of public spaces and green areas. The shaping of the urban landscape is signifi cantly associated with innovation [Bach-Głowińska 2014]. As a result of research into the relationship between space, the sense of belonging and innovation, there are some initial recommendations for providing elements that stimulate the user’s creativity while shaping the urban landscape. In the developed methodology of the smartest place, the determination of stakeholders takes place, among others thanks to the use of an online survey, then meetings are held with those involved in the co-creation session, which aim to definitively determine the form of landscape that best suits their needs and at the same time have the chance to stimulate their creativity

Abstract

The basic resource of urban planning is space, which as a result of transformation has a direct impact on socio-economic development and quality of life. The author’s purpose was to define planning solutions for urban spatial policy, which can raise the quality of living, especially in the residential environment. In connection with the above, the literature of the subject was analysed and examples of good spatial policy and urban development in the living environment were shown. Particular attention was paid to the planning solutions in Paris and Vienna, as well as to the examples of the new living environment creation in some Scandinavian cities.

Abstract

The main objective of the article is to assess the changes in carbon dioxide emissions in residential sector caused by the implementation of the plans contained in the Air Protection Programs, anti-smog resolutions adopted in 9 voivodeships and the nationwide “Clean Air” program. The reduction of emissions of pollutants which directly affecting air quality and human health, i.e. particulate matter and benz(a)pyrene, which residential sector is the main source, can also affect the amount of emitted of carbon dioxide. To determine the changes in carbon dioxide emissions in the residential sector, emissions of CO2 in base year of 2017 from various energy carriers were determined, plans for reducing of low-stack emission were reviewed and the future structure of energy carriers used in households was estimated. The processes of increasing the efficiency of energy use through both the replacement of boilers and thermomodernization were also taken into account. The obtained results show that the highest CO2 emission reduction of 6% is achieved in case of “Clean Air” program. In frame of this program in 3.5 million of single-family houses a heating system replacement and thermomodernization is planned. Implementation of plans included on Air Protection Programs and anti-smog resolutions can lead to a relatively small (approx. 1%) reduction of CO2 compared to base year 2017. The detailed results of future fuel consumption and CO2 emission for individual voivodeships and for the whole of Poland was presented.

Abstract

According to the Grant Map of the Ministry of Development (MoD) as of March-April 2017, there were 1716 urban regeneration (revitalization) projects implemented in Poland between 2007-2013. Data from 11 voivodeships (out of 16 regions NUTS 2 in Poland) and 977 projects was sufficient to provide a representative sample (56,9% of projects presented in the Grant Map). The main methods used in the article included observation and review of MoD statistical data and literature on the subject. As observed by the author, between 2007-2013 the definition of urban regeneration (revitalization) was only mentioned in one of the footnotes to the housing guidelines, which was a poor legal basis for the regional managing authorities. Similarly, there was no solid basis in the strategic documents (national) for that period: they did not provide any definition of revitalization. It was in the interest of the beneficiaries, as well as – partly – in the interest of those managing authorities to satisfy the local needs, especially those needs which were not considered the result of the shift to the post-industrial era, but rather as a result of numerous institutional and political events. Due to these features, the period 2007-2013 was dominated by infrastructure projects aimed at the quality of life but also efficient in terms of spending European money. It seems that there was an agreement between regional managing authorities and the benefi ciaries (potential voters) as to the way of spending the revitalization funding. This was understood differently at national level, but because institutions at this level were not involved directly in the urban regeneration (revitalization), their influence on regional units was minor. Even more so because the managing authorities were also interested in speeding up the process of spending European resources.
