  • THE ROLE OF DAYLIGHT IN ARCHITECTURAL CREATIONS OF CONTEMPORARY CULTURAL FACILITIES
    • Małgorzata Rogińska-Niesłuchowska
    2018

    The paper studies the role of light in architectural creations of contemporary buildings of representative function. Based on the selected projects and completed buildings dedicated to culture and art, it analyzes and systematizes the examples of using light to obtain visual effects that mark the architecture with a universal and timeless message. The method of research is case study and critical analysis of literature. Light plays a particularly significant role in shaping contemporary buildings of cultural function. Nowadays, architects designing meeting places of cultural importance refer to the oldest traditions of sacral architecture and places of worship, where light played a vital role. Contemporary buildings of culture and art have become the scene of experiment with light, where modern design techniques, new technologies of materials and facade systems are employed. Both, natural and artificial light, make up an indispensable material of architecture, treated on a par with other materials. In modern times, the protection of the environment, as well as human health are in the focus of attention. Protecting the city against light pollution and striving for maximum energy efficiency of buildings are now of top priority. Therefore, the idea of architecture using daylight gains more significance. It brings to mind the ancient architecture as the daylight gives the contemporary architecture a special, timeless atmosphere. The use of computer designing methods, technologically advanced materials, and glassing creates a special prospect for the architecture of daylight. A significant role of daylight manipulation can be seen in some architectural realisations and these buildings take on the role of icons in contemporary architecture.

  • The role of Herzberg-Teller effects on the resonance Raman spectrum of trans-porphycene investigated by time dependent density functional theory.
    • Julien Guthmuller
    2018 Full text JOURNAL OF CHEMICAL PHYSICS

    The S1 excited state properties as well as the associated absorption and resonance Raman (RR) spectra of trans-porphycene are investigated by means of time dependent density functional theory calculations. The relative magnitude of the Franck-Condon (FC) contribution and of the Herzberg-Teller (HT) effects is evaluated for both the absorption and RR intensities. The accuracy of the calculated spectra is assessed by employing different theoretical approximations and by comparing with experimental data. The obtained results show that Duschinsky effects lead to noticeable modifications in the absorption intensities but are nearly negligible in the RR spectrum. By contrast, the HT effects are stronger for the RR intensities compared to the absorption intensities, and these effects significantly improve the agreement with the experimental RR spectrum. Moreover, the HT effects produce different values of the RR depolarization ratios, which can be used to quantify the relative importance of the FC and HT contributions. Generally, it is found that the HT effects have a significant role on the RR spectrum of trans-porphycene and that their inclusion in the computational scheme is mandatory to accurately predict the RR intensities.

    2018 Full text Miscellanea Geographica : Regional Studies on Development

    In civil societies, urban movements are one of the tools in the process of spatial governance. In Poland, urban activism is beginning to develop together with a budding participation in public life. Therefore, there is a need to assess the scope and effects of the urban movements’ actions. The aim of the study was to determine and evaluate their impact on the spatial development in three Polish cities - Poznań, Gdańsk and Gdynia, especially in regard to the procedures in local urban planning and the process of participation. On the basis of the data collected during research and community interviews conducted in these cities, the following factors were analysed: the background and current profile of urban movements, the extent, regularity and effectiveness of their actions, the planning and spatial development initiatives undertaken, their cooperation with the local authorities and their contribution to the enhancement of participatory mechanisms.

  • The Sea And The Beach As Composition Elements Of The Coastal Gardens In West Prussia In The 19th Century
    • Anita Jaśkiewicz-Sojak
    • Maura Zaworska
    2018

    The melancholic and changeable character of the Baltic Sea has often been used in the painting of the romantic period. The sea and its beaches were also an important composition element as well as a supplement of Baltic coastal gardens which were founded in West Prussia in the 19th century. Gardens set up on the coast used various moods of nature, as well as extensive and beautiful sea landscapes, often leading to nostalgia. The spectacle of the sea was becoming an element of a park: a real element – a spatial part, absorbing attention and senses, as well as a subconscious one – creating atmosphere and leading to nostalgia. The landscape garden located next to the palace in Rutzkau (currently Rzucewo), which was designed by Peter Joseph Lenné in the middle of the 19th century, is an exceptional example of using the sea and the beach space. In Zoppot (Sopot) or Oliva (nowadays Gdańsk-Oliwa) various manors and coastal villas were accompanied by gardens with vistas and view openings overlooking the sea and the beach. Another interesting group of coastal gardens included spa parks in Danzig (Gdańsk) or Zoppot as well as in other smaller spa locations. The analysis of the seascape and the sea as integral elements in coastal gardens shows new aspects of landscape art, and develops studies of landscape architecture in West Prussia. This side of the topic of Baltic coastal gardens in West Prussia has not been the subject of comprehensive research until now. The knowledge about this link between garden and water is very specific and important for history of landscape architecture in West Prussia (formerly a German region, currently a part of Poland). Also acknowledging the heritage of Prussian gardens has great impact on their conservation and preservation.

    2018 Full text Open Engineering

    In the article is presented an analysis of the life cycle costs calculation for selected roof coverings. The scope of research includes costs of construction, maintenance and demolition of the roof covering structure for two alternative technologies – the traditional and new generation. On the presented example of an industrial building with a roof area of 1000 m², the above costs are taken to consideration for the roof covering made of two thermoplastic asphalt torching polymer membrane layers and a new generation PVC thermoplastic film with a reinforcing layer. The input data presented in the article comes from the investor (the owner of the future facility) and from property managers responsible for the maintenance of facilities in regard to the purpose, volume and applied method. The subject of the research is the analysis of the range of impact of the selected roof covering technology on the long-term costs of its maintenance. The aim of the research conducted by the authors is to indicate the possibility of reducing the costs related to the maintenance and elimination of a selected building structure (roof covering) in the assumed period of its operation for 70 years.

  • The significance of the properties of water for the working cycle of the kinesin molecular motor
    • Anna Kuffel
    • Monika Szałachowska
    2018 Full text JOURNAL OF CHEMICAL PHYSICS

    Explicit solvent molecular dynamics simulations were performed in this study to investigate and discuss several aspects of the influence of the properties of water on the working cycle of a molecular motor from the kinesin superfamily. The main objects of attention were: the binding of the neck linker and the association of the kinesin and the tubulin. The docking of the neck linker is considered a crucial event during the working cycle and is said to be the one that contributes to propelling the motor forward. Herein, it is demonstrated that the solvent contributes to the force-generating mechanism of the motor—the absolute value of the force generated by the linker depends on the properties of the solvent. The force can also depend on the instantaneous conformation of the protein. Our results show that the force may not be strictly the same during every step, as well as during the whole process of the docking, but we checked that even the smaller forces measured by us were big enough to propel the kinesin head along the protofilament with the required speed. It is also shown that the dynamics of the process of approach of the kinesin to its binding site on the microtubule track changes rapidly as the proteins come closer. The influence of the properties of interfacial water on the kinetics of this process is discussed here.

  • THE SITUATION OF WOMEN IN THE POLISH LABOUR MARKET IN THE LIGHT OF CHANGES IN THE PENSION SECURITY SYSTEM
    • Małgorzata Gawrycka
    • Dagmara Nikulin
    2018 Full text PRACE NAUKOWE UNIWERSYTETU EKONOMICZNEGO WE WROCŁAWIU

    The aim of the study is to examine the opinion of a group of women on their economic activity and decisions related to retirement. The first part of the article reviews previous research related to the economic activity of older people with a special focus on women. In the empirical part of the article, women’s opinions on issues related to retirement were analyzed. The research was carried out in 2016 on a sample of 45 women, which is a non-representative sample selection technique. The method used is similar to the method of “random choice” or “convenience choice” (convenience sampling). Research results indicate that retirement was often not fully voluntary, and resulted from the liquidation of the workplace or from the bad atmosphere. The time of retirement for women is primarily a period when they can fulfill their plans and dreams.

  • The spatial planning of industrial areas in an urbanized area for cargo, in the development of inland waterway transport
    • Patrycja Jerzyło
    • Aleksandra Wawrzyńska
    2018 Full text E3S Web of Conferences

    Spatial planning, taking into account the configuration of the surface, i.e. its shape (relief) and the presence and mutual location of objects and points of characteristic water ports, is a derivative of several natural, economic, market, technical, social and political factors. It depends on the destination port, the planned structure of trade in cargo, the forecasted traffic of ships, passageways, the technology of reloading used, as well as on the anticipated demand for the development of shipping and trade by sea and inland waterway. The article analyzes the transport accessibility of the Port of Gdynia through the construction of a dock to determine the proposals for improving the conditions of transported cargo.

  • The structurally similar TRFH domain of TRF1 and TRF2 dimers shows distinct behaviour towards TIN2

    2018 ARCHIVES OF BIOCHEMISTRY AND BIOPHYSICS

    The telomere repeat binding-factor 1 and 2 (TRF1 and TRF2) proteins of the shelterin complex bind to duplex telomeric DNA as homodimers, and the homodimerization is mediated by their TRFH (TRF-homology) domains. We performed molecular dynamic (MD) simulations of the dimer forms of TRF1TRFH and TRF2TRFH in the presence/absence of the TIN2TBM (TIN2, TRF-interacting nuclear protein 2, TBM, TRF-binding motif) peptide. The MD results suggest that TIN2TBM is necessary to ensure the stability of TRF1TRFH homodimer but not the TRF2TRFH homodimer. In TRF1-TIN2-TRF2 complex, the peptide enhances the protein-protein interactions to yield a stable heterodimer. Both monomers in TRF1TRFH homodimer interact almost equally with the peptide, whereas in TRF2TRFH homodimer, monomer TRF2TRFH(M1) exhibits more dominant interactions than the TRF2TRFH(M2). The common residues of TRF1/2TRFH(M1) that form interactions with TIN2TBM in all peptide-bound systems originate from the H3 (helix) and L3 (loop) regions. Additionally, in the homodimer systems, residues of TRF1/2TRFH(M2) also interact with the peptide. The residue pair E71-K213 is responsible for different conformations of TRF1TRFH homodimers; specifically, this residue pair enhances the protein-peptide/protein interactions in peptide-bound/unbound systems, respectively. TRF1TRFH and TRF2TRFH proteins have a conserved but different interface responsible for the protein-protein/peptide interactions that exist in the corresponding dimers.

    In this work rigid polyurethane foams (PUR) were obtained by replacement of 0–70 wt% of petrochemical polyol with bio-polyol obtained via cellulose liquefaction in presence of crude glycerol. The foams with different content of a bio-polyol were prepared by single step method for NCO/OH ratio equals 1.5. The prepared materials were analyzed in terms of their morphology, chemical structure, thermal stability and basic physical and mechanical properties. The effects of photo-oxidative and thermo-oxidative aging on chemical structure, apparent density and mechanical properties of the biomass based rigid polyurethane foams were investigated and discussed.

    The synthesis of a potential immunosuppressant, i.e. dimethyl ester of N-mycophenoyl malonic acid was optimized in the reaction of mycophenolic acid (MPA) with amino malonic dimethyl ester in the presence of propanephosphonic anhydride (T3P) as a coupling reagent. The structural properties of the obtained MPA derivative were investigated by NMR, MS and single crystal X-ray diffraction methods. Theoretical considerations of conformational flexibility based on DFT calculations are presented

    2018 Full text

    This paper refers to the problem of shepherding clusters of passive agents consisting of a large number of objects by a team of active agents. The problem of shepherding and the difficulties that arise with the increasing number of data describing the location of agents have been described. Several methods for reducing the dimensionality of data are presented. Selected autoencoding method using a Restricted Boltzmann Machine is then discussed. Autoencoding is deployed to reduce the dimensionality of graphic representation of clusters. Reduced data is used to train the neural network which determine movements of the active agents. Genetic algorithms are used in optimization of the parameters of this network.

  • The Use of Big Data in Regenerative Planning

    2018 Full text Sustainability

    With the increasing significance of Big Data sources and their reliability for studying current urban development processes, new possibilities have appeared for analyzing the urban planning of contemporary cities. At the same time, the new urban development paradigm related to regenerative sustainability requires a new approach and hence a better understanding of the processes changing cities today, which will allow more efficient solutions to be designed and implemented. It results in the need to search for tools which will allow more advanced analyses while assessing the planning projects supporting regenerative development. Therefore, in this paper, the authors study the role of Big Data retrieved from sensor systems, social media, GPS, institutional data, or customer and transaction records. The study includes an enquiry into how Big Data relates to the ecosystem and to human activities, in supporting the development of regenerative human settlements. The aim of the study is to assess the possibilities created by Big Data-based tools in supporting regenerative design and planning and the role they can play in urban projects. In order to do this, frameworks allowing for the assessment of planning projects were analyzed according to their potential to support a regenerative approach. This has been followed by an analysis of the accessibility and reliability of the data sources. Finally, Big Data-based projects were mapped upon aspects of regenerative planning according to the introduced framework.

    There are many factors that influence accidents and their severity. They can be grouped within the system of man, vehicle and environment. The article focuses on how GIS tools can be used to manage road infrastructure safety. To ensure a better understanding and identification of road factors, GIS tools help with the acquisition of road parameter data. Their other role is helping with a clear and effective presentation of risk ranking. GIS is key to identifying high-risk sections and supports the effective communication of safety levels. This makes it a vital element of safety management. The article describes the use of GIS for the collection and visualisation of road parameter data which are not available in any of the existing databases, i.e. horizontal curve parameters. As we know from research and statistics, they are important factors that determine the safety of road infrastructure. Finally, new research is proposed as well as the possibilities for applying GIS tools for the purposes of road safety inspection.

  • The Use of Gravimetric Measurements to Determine the Orthometric Height of the Benchmark in the Port of Gdynia
    • Krzysztof Pyrchla
    • Jerzy Pyrchla
    2018 Acta Ethnographica Hungarica. An International Journal of Ethnography

    This paper contains a description of the technology used to make gravimetric measurements of the height of a reference point located in the Port of Gdynia, Poland. Measurements were made using a CG-5 gravimeter manufactured by LaCoste & Romberg Scintrex Inc., and determinations of position used a Leica Viva GS15 receiver integrated with a network of HxGN SmartNet GNSS reference stations. The measuring methodology required gravimeter readings to be taken at an absolute measurement station in the Polish official gravimetric network and at new stations. The adopted profile method entailed making a two of measurements at all stations. The measurements relate to terrain with a relatively small height difference between the starting point and end point. It is standard in such cases to assume that gravitation varies linearly with height. This assumption is better satisfied when the gravimetric series is shorter and there is less height variation within it.

    2018 Full text Archives of Thermodynamics

    Nowadays, the energy cost is very high and this problem is carried out to seek techniques for improvement of the aerothermal and thermal (heat flow) systems performances in different technical applications. The transient and steady-state techniques with liquid crystals for the surface temperature and heat transfer coefficient or Nusselt number distribution measurements have been developed. The flow pattern produced by transverse vortex generators (ribs) and other fluid obstacles (e.g. turbine blades) was visualized using liquid crystals (Liquid Crystal Thermography) in combination with the true-colour image processing as well as planar beam of double-impulse laser tailored by a cylindrical lens and oil particles (particle image velocimetry or laser anemometry). Experiments using both research tools were performed at Gdańsk University of Technology, Faculty of Mechanical Engineering. Present work provides selected results obtained during this research.

  • The use of plate springs for preloading of a system of tapered roller bearings of a wind turbine gearbox
    • Bartosz Bastian
    • Michał Wasilczuk
    2018 Full text TRIBOLOGIA

    The use of preloaded tapered roller bearings in wind turbine drive systems allows a transfer of load in the case of high variations of axial forces. The examined bearing system, a modification of a current design, consists of a pair of different sized bearings. Previous study showed the high sensitivity of tapered roller bearings on the existing radial interference. Dimensional tolerances used in the original design do not allow obtaining precise values of preload required for slippage-free operation of bearings with varying wind turbine load conditions. With the aim of achieving expected preload values, the use of plate springs (Belleville springs) is proposed. The springs will allow creating an axial force, independently of real dimensions in a modernised unit. Furthermore, it is very important in the case of gearbox retrofits to be executed up in the wind turbine nacelle without dismantling the gearbox.

  • The use of RP-HPLC–Q-TOF–MS as a powerful tool for wastewater composition profiling and selection of water pollution marker specific to wastewater contamination

    Limited drinking water resources and water pollution are one of the main worldwide problems. To reduce the consumption of fresh water resources, the use of treated wastewater has been proposed. The farmlands have been irrigated with wastewater for centuries, but the composition of used sewage has changed over the years. Recent research has revealed the presence of hundreds of new organic contaminants in many environmental waters, including wastewaters and their receivers. For this reason, wastewater profiling and monitoring are of high importance and urgent need. In this study, the HPLC–Q-TOF–MS has been used for the profiling of wastewater composition and evaluation of the water pollution markers belonging to emerging contaminants. Three different solid-phase extraction approaches were applied to obtain the best results. Compounds such as acesulfame-K, caffeine, carbamazepine, cyclamate, ibuprofen, methyl paraben, paracetamol, or saccharin were detected in raw wastewater samples, whereas only acesulfame-K, carbamazepine, and sucralose were found in effluent samples. It seems that these particular compounds might be chosen as water pollution marker specific to Polish communal sewages.
