Abstract

The significance of American expos in the history of world’s fairs, as well as in the history of planning, urban design, architecture and landscape architecture, is extraordinary. In the article, which constitutes a supplement to the first part of a report on the carrying out of the research project entitled “Urban and architectural heritage, as well as the impact of American world expos on city planning and development”, a retrospective outlook on American fairs has been presented on the examples of Philadelphia, Buffalo, Saint Louis and Cleveland, with a particular focus on traces of expos left in the cityscape and their long-term heritage, which affects the development of host-cities.

Abstract

Kinetic studies of esterification reaction of maleic anhydride with butan-1-ol, 2-methylpropan-1-ol and butan-2-ol were carried out in a semibatch reactor, in the presence of four acidic catalysts: sulfuric acid, phosphotungstic acid, ion exchange resin Dowex 50WX8 and tetrabutyl zirconate. Phosphotungstic acid proved to be the most active catalyst. The temperature range was 383–413 K, the initial molar ratio of alcohol to acid ranged 2.2-5:1. The kinetic parameters were given. The kinetics appeared to be that of the second order with respect both to the acid and to the alcohol. The reaction carried out in the presence of tetrabutyl zirconate was very slow and depended only on acid concentration. The effect of temperature on the reaction rate follows the Arrhenius equation well.

Abstract

The aim of the research presented in this paper was to determine the effect of vessel scale on gas hold- up in gas-liquid systems. The agitated vessel with internal diameters of T = 0:288 m and T = 0:634 m was filled with a liquid up to the height H = T. For the purpose of measurements, two high-speed impellers were used: Rushton turbine impeller (RT) or A 315 impeller.Within the study, the following parameters were altered: superficial gas velocity, impeller speed, impeller type and concentration of aqueous sucrose solution. In addition, influence of the vessel scale on gas hold-up value was analysed. Experimental results were mathematically described. Equations (5)–(7) do not have equivalents in the literature.

Abstract

Thermoelectric generators using the Seebeck effect to generate electricity are increasingly used in various areas of human activity, especially in cases where a cheap high-temperature heat source is available. Despite many advantages, TEG generators have one major disadvantage: very low efficiency of heat conversion into electrical power which strongly depends on the applied load resistance. There is a maximum of generated power between the short and the open circuit in which it is zero. That is why optimization of TEG modules is particularly important. In this paper a method of maximization of generated power in a single TEG module is presented for two cases. The first case concerns a problem with fixed heat flux flow into the hot side of the module whereas the second one concerns a problem with fixed heat transfer parameters in hot heat exchanger i.e. supply gas temperature and heat transfer coefficient. A number of optimization results performed for various values of these parameters are presented and discussed.

Abstract

The study aimed to produce nano- and microfibrous materials from polyurethane (ChronoFlex®C75A/ C75D in 1,1,1,3,3,3–hexafluoro–2–propanol) by solution blow spinning. Experiments were carried out in order to determine the impact of solution blow spinning parameters on fibre diameter and quality of produced materials. The following properties of produced fibre scaffolds were investigated: fibre size, porosity and pore size, wettability, and mechanical properties. The results confirmed that produced nano- and microfibrous materials could be potentially used as scaffolds in three-dimensional cell and tissue cultures.

Abstract

In this study, we performed the qualitative analysis of exoproteins during granule formation in the pres- ence or in the absence of cations. The staining of thin granule cryosections showed that nucleic acids, proteins, polysaccharides and calcium cations were the dominant components of the granules. Proteins are the structural components associated with calcium ions. We determined changes in the proteomic profile and tightly bound extracellular polymeric substances (EPS) of the slime. The exopolymeric matrix containing the proteins was extracted using the Dowex resin method. Proteomic profile was analysed by SDS-PAGE method (sodium dodecyl sulphate polyacrylamide gel electrophoresis) using Coomassie blue staining in the samples of the aerobic granule matrix formed in the presence of multivalent cations and compared with that of the aerobic granules cultivated without cations. The results indicate that the granule matrix is predominantly composed of large and complex proteins that are tightly bound within the granular structure. The tightly bound extracellular polymeric substances (TB-EPS) may play a role in improved mechanical stability of aerobic granules. In the supernatant fraction of the sludge, only a small amount of free proteins in the medium molecular mass range was detected. The protein with high molecular mass ( 116 kDa) produced in the reactors with added Ca2+. Ca2+ had a considerable regulatory influence on production of extracellular proteins during aerobic granulation.

Abstract

The focus point of this article is the territory of historical greenery (THG) of landscape architecture (LA) as a result of interaction between material environment design as applied art and society. As an object of applied art and anthropogenic activity, LA, as well as its research is an important area for natural, anthropogenic, social and economic sustainability. The study of THG problems today is based on the innate human right to live in a harmonious space of both aesthetic material and natural environment. Aesthetic quality criteria are important for understanding the systemic relationships between nature and human interaction embodied in LA as an applied art form. Therefore, the anthropogenic objects of LA and the spaces formed by them in the urban environment require studies of the material and natural environment and the anthropogenic functioning as a whole. Based on heuristic, qualitative and quantitative research methods and case studies, the article discusses the problems of interaction between present anthropogenic and natural processes, as well as the possible influence of such interactions on scenarios of LA development and future management of the territory of historical greenery.

Abstract

The state of the built environment makes one inclined to ponder how ethics affects the space that is designed and its aesthetic quality. As a consequence, there arise questions concerning the provisions of ethical codes of professional conduct that architects must adhere to on the one hand, while on the other, the practical guidelines for architectural design and planning. In a period when matters of durability (firmitas) and utility (utilitas) have been largely dominated by other branches of design, including the matters of ecology, beauty (venustas) has come to be considered as the most essential constituent attribute of architecture. Selected interpretations of Beauty and its relationship with Good (Vitruvius, 1954; Tatarkiewicz, 1962, 1982) have been presented, including in light of the latest findings of neurobiology and neuroaesthetics (Zeki, 2011, 2019; Qiuling et al., 2018; Ishizu, Tsukiura, Cabeza, 2011). The term appropriateness (Krakowski, 1989) is herein accepted, understood as a notion of intentional, socially conditioned beauty and considered proper to describe the aesthetic standard of the built environment under design. This paper is an attempt at finding practical methods of ensuring aesthetic quality (beauty) in newly designed and redesigned spatial situations. It identifies the field of professional law (the ethical code of conduct for architects), wherein aesthetic matters are largely ignored on the one hand, while on the other it points to the necessity to teach and implement a design process that is tender (Tokarczuk, 2019) and mindful (Dominiczak, 2016) dialogue in a specific understanding of encounters with the Other (the Second), whether it’s an architect, a user or a structure. It notes the proposal of creative aesthetics (Sławińska, 1973) as a potentially possible integral branch of design. Contrary to the professional ethics of architects, which pertains to individuals who practice design and are ethically responsible for their professional conduct (design), the ethic of architecture refers to aesthetic relationships that emerge in architectural situations (Dominiczak, 2016). In this understanding, built structures are personified and seen as entities with their own identities (if the designer wills it) that engage in dialogue with Other entities (Levinas, 1998), which both create and define a given space.

Abstract

The East of Europe stays at present on the background of interests in the new architecture. Meanwhile Moscow is a major city of Europe and there many interesting implementations are occurring. For her the office market intensively is being extended, at least in contrast with countries of the free market democracy, it is playing the political factor there major part. From interesting implementations they mentioned the Moscow International Business Centre as about the big urban planning operation and about Dominion Building Office as about interesting Zaha Hadid work.

Abstract

This article discusses the multi-threaded and multi-dimensional process of preparing a technical designs that lead to the introduction of new forms of use into existing urban and architectural structures of high historical value. It covers research concerning formal and spatial determinants, associated with local law in selected European countries. Its results point to concise, precise and easily understandable provisions in terms of local law concerning planned development in areas under heritage conservation, which is conducive to a climate of social acceptance of constraints and prohibitions that — some — may consider significant.

Abstract

This paper discusses the study of the atmosphere of architecture, which places human perception of space at the centre, and thus expands the humanist aspect of architectural and urban theory and design. Referring her own research to the current state of the art, the author presents various definitions of atmosphere and methodologies of its description, which considerably encroach into the field of neurophysiology and psychology, but also value contemplation, literary descriptions, photographs and stage design in a new light.

Abstract

The art of architecture and the art of cooking are fields, where we can find numerous social and spatial relationships. This publication will enumerate the most important of these and discuss solutions, that promote moderation in using resources, space and aesthetic means, that are based on knowledge arising from context and the human scale, and that points to the necessity to slow down the pace of our lives, which are the major challenges in the face of contemporary civilisational changes.

Abstract

The article outlines an idea that, according to the author, could serve as a ‘philosophical reinforcement’ of interdisciplinary trends in contemporary urbanistic theory. Assuming that the reflection on the philosophical aspects of the urbanistic order will help in the conceptualization of policies that respond more effectively to today’s crisis in the urban environment, the author attempts to articulate questions that could facilitate a dialogue between urban planners and philosophers. He focuses his attention on the issues of the philosophical basis of the new urban structure of the city in the first half of the 21st century. The idea behind this cultural project was called the City of Values 21 ( CV-21).

Abstract

The paper presents the results of the research on the assessment of environmental conditions in selected university buildings — focused on building-surroundings relations. The research was conducted in 5 buildings in a few academic centers in Poland, using questionnaire technique. The respondents were students of architecture, art, psychology and landscape architecture, in the surveyed buildings (N=184). Analysis of the results — apart from the main finding of the general lack of the ‘space for students’ (including both individual workplaces and recreational spaces) — revealed the important role of the surroundings for the way of use and description of the buildings. ‘Location’ and generally ‘external’ elements such as garden, greenery and small architecture for recreation, the ‘edges’ of the building (such as the elevation and the roof) as well as the direct visual connections, constituted the largest group among all respondents’ ‘strengths’ of analyzed buildings. A significant and puzzling exception in this group is the latest in the analyzed WICA building in Lublin — best evaluated in terms of functionality but also described with the most neutral terms (on the ‘positive’ scale), whose students (N=31) in their assessments and descriptions do not take into account (or do not notice) the building-environment relationship. The analysis of the results revealed individualized image of the places. ‘Functionality’ occured to be not the only one predictor of behavioral and emotional bonds with places; the important role is also — as it seems — played by a ‘friendly’ environment. This — basing on the analysis of the content — means both selected aspect of urban relationships (accessibility, public transportation, facilities), but also the quality (beauty and utility) of landscape architecture.

Abstract

The increasing demand for office space in Moscow, as well as the economic and political conditions in the global context, have contributed to the construction of a multifunctional complex of the Moscow International Business Centre in the Russian capital. The primarily office building complex is an example of activities consisting in the degleration of offices outside the city centre. It is also an attempt to create a prestigious place (including attractive architecture), an element of the city identity indicating a high development level of the state, application of new solutions in the fields of urban planning and architecture (including technique and modern technologies). Key words: Moscow International Business Centre, multifunctional office complex, office building, urban operation, post-industrial reconstruction, Moscow

Abstract

Zaha Hadid was a starchitect, trying to fulfil the mission of pursuing new shapes in her many designs and projects, often shocking others with extravagant forms that were unthinkable in the traditional understanding of our reality. The author of this paper presents a proposal of dividing her work into three tendencies: an inspiration with Constructivism, Biomorphism and Expressionism.

Abstract

Celem artykułu jest wskazanie potrzeby przywrócenia racjonalnego podejścia do dzisiejszego planowania urbanistycznego i architektury. Wiele badań i projektów dotyczących współczesnego miasta koncentruje się głównie na różnych rodzajach „nowatorskich” konfiguracji miejskich, które mają poradzić sobie z obecnymi i przyszłymi problemami. Wydaje się jednak, że często brakuje w nich historycznej, kulturowej, psychologicznej i społecznej świadomości. A przecież postrzeganie i rozumienie miasta opiera się głównie na jego obrazach, wspomnieniach i konotacjach z przeszłości. Wciąż podejmowane są próby zbliżenia się do racjonalnej równowagi między starym a nowym, tradycyjnym a nowoczesnym, formą a funkcją, pięknem a postępowymi aspektami miasta. Tekst stanowi studium przypadku dzielnicy Amsterdamu — IJburg — jako przykładu dużego przedsięwzięcia, który może ułatwić omówienie roli i potencjału tkwiącego w tradycyjnej typologii urbanistycznej i architektonicznej, pomocnego w procesie tworzenia nowych układów miejskich. Wnioski przedstawione w tekście, oparte na analizowanym projekcie dzielnicy IJburg, koncentrują się na wskazaniu typów urbanistycznych i architektonicznych z przeszłości jako narzędzi projektowych, które wciąż mogą zapewniać niezwykłe twórcze i instrumentalne możliwości oraz funkcjonować jako nośniki znaczenia i tożsamości kulturowej.
