Modeling the Structure, Dynamics, and Transformations of Proteins with the UNRES Force Field
PublikacjaThe physics-based united-residue (UNRES) model of proteins ( www.unres.pl ) has been designed to carry out large-scale simulations of protein folding. The force field has been derived and parameterized based on the principles of statistical-mechanics, which makes it independent of structural databases and applicable to treat nonstandard situations such as, proteins that contain D-amino-acid residues. Powered by Langevin dynamics...

On Kinetic Nature of Hysteresis Phenomena in Stress-Induced Phase Transformations
PublikacjaA simplest model is developed which demonstrates that hysteresis phenomena in stress-induced phase transformations may have a kinetic nature and follow from the discrepancy between strain rate and characteristic rate of the new phase growth.

Computational Analysis of Transformational Organisational Change with Focus on Organisational Culture and Organisational Learning: An Adaptive Dynamical Systems Modeling Approach
PublikacjaTransformative Organisational Change becomes more and more significant both practically and academically, especially in the context of organisational culture and learning. However computational modeling and formalization of organisational change and learning processes are still largely unexplored. This chapter aims to provide an adaptive network model of transformative organisational change and translate a selection of organisational...

THE PANTOGRAPH AND ITS GEOMETRIC TRANSFORMATIONS - A FORMER POPULAR TOOL FOR COPYING AND SCALING
PublikacjaDevelopment of digital technology has resulted in significant transformations of designer workshops. Computer applications replaced the previously existing tools and methods for drawing up of projects. Professional, sophisticated drawing instruments and tools for manual plotting, as well as basic drawing aids, have gradually fallen into oblivion and become relicts of a bygone era - the objects of collectors' interest. Gdansk University...

Influence of heat transformations on microstructure and properties of some wrought aluminium alloys.
PublikacjaOmówiono wpływ spawania na podatność do korozji naprężeniowej stopów Al-Mg i Al-Zn-Mg stwierdzając, że wzrost zawartości cynku wywołuje wzrost właściwości mechanicznych i spadek odporności na korozję naprężeniową. Wykazano, że obróbka cieplna złożona z retrogresji i powtórnego starzenia w przypadku stopów Al-Zn-Mg nie powoduje szczególnych zmian odporności na korozję naprężeniową, co pozostaje w związku z niewielką zmianą struktur...

Comparison of Renewable Energy Sources in ‘New’ EU Member States in the Context of National Energy Transformations
PublikacjaThe European Union strives to create sustainable, low-carbon economies; therefore, energy policies of all member states should move towards renewable energy sources (RES). That concerns also the so-called new EU member states. These countries, on the one hand, are characterized by significant historical similarities in terms of post-communist legacy and adopted development strategies linked with the EU membership, and on the other...

Dynamic electrochemical impedance spectroscopy of the adsorption and relaxation of polianiline chains during potentiodynamic redox transformations
PublikacjaZaprezentowano nowe podejście do analizy widm impedancyjnych uzyskanych dla warstwy przewodzącej polianiliny (PAni). Właściwości powyższej warstwy są często modelowane przy użyciu elementu stałofazowego (CPE), który w sposób dokładniejszy odzwierciedla wyniki eksperymentalne niż klasyczny element pojemnościowy (kondensator). W pracy zaproponowano nowy elektryczny obwód zastępczy oparty na modelu adsorpcyjnym Frumkin-Melik-Gaikazyan,...

Public art in the era of urban transformations. A case study of Eduardo Paolozzi’s artistic output in Edinburgh and in London
PublikacjaUrban space dedicated to cultural life, entertainment or business is currently exposed to dynamic urbanistic transformations. Monumental works of art within the boundaries of cities, for years embedded in the urban landscape and awareness of viewers, are moved to other places or even destroyed. Decisions about a change of their location and context, which are fundamental aspects for the impression made by a given work of art, cause...

Applying ground penetrating radar to tracking of ancient architectural transformations: the case of the monastery St. Peter on the Island of Rab (Croatia)
PublikacjaThe ground-penetrating radar (GPR) method has been used for many years in archaeological research. However, thismethod is still not widely used in studies of past architecture. The biggest problem with the implementation of the GPRmethod at such sites is usually connected with extensive debris layers, plant cover and standing relics of walls and otherfeatures that restrict the available measurement area. Despite of these, properly...
