Opis:
E. Tutaj has introduced classes of Schauder bases termed "unconditional-like" (UL) and "unconditional-like*" (UL*) whose intersection is the class of unconditional bases. In view of this association with unconditional bases, it is interesting to note that there exist Banach spaces which have no unconditional basis and yet have a basis of one of these two types (e.g., the space [0,1]). In the same spirit, we show in this paper that the space of all compact operators on a reflexive Banach space with an unconditional basis has a basis of type UL*, even though it is well-known that this space has no unconditional basis.

The influence of sun rays, wind speed, and different type of subsoil on the evaporation process was analyzed. A dedicated experimental set-up for investigation of evaporation process of three liquids (ethanol, petrol and tap water) deposited on glass and sand was created. Results indicated that for porous surfaces wind decreased the amount of evaporated liquids. After substitution of wind with sun rays for porous surface evaporation process increased for ethanol and petrol, respectively. Finally, the influence of both wind and sun rays indicated a 1% and 5% decrease of evaporation intensity for tap water and petrol, respectively. While, a 2% increase of evaporated liquid was observed for ethanol. It was noticed that application of porous surface caused the highest improvement of evaporation process for petrol and tap water, while the lowest for ethanol. Moreover, application of wind together with porous surface increased the intensity of evaporation for all analyzed liquids.

The equation which describes the small vibrations of a nonhomogeneous damped string can be rewritten as an abstract Cauchy problem for the densely defined closed operator iA. We prove that the set of root vectors of the operator A forms a basis of subspaces in a certain Hilbert space H. Furthermore, we give the rate of convergence for the decomposition with respect to this basis. In the second main result we show that with additional assumptions the set of root vectors of the operator A is a Riesz basis for H.

Opis:
Constitutional principles and norms are the basis of the environmental policy of the Belarusian state at the present stage of its existence. They determine the limits, intensity, methods of its implementation, the degree of participation in the implementation of environmental policy of both the state bodies and civil society institutions. The scientific methods of cognition used in the research include analysis, synthesis, abstraction and comparative method. The study concluded that environmental protection in the Republic of Belarus is a set of measures, a system of state, international and public measures for the rational use, protection and restoration of natural resources, protection of the environment from pollution and destruction in order to create the most favourable conditions for the existence of human society, to meet the material and cultural needs of both living and future generations based on the constitutional principles and norms. Environmental protection can be considered as an independent constitutional principle underlying the modern policy of the Belarusian state.

Opis:
The central goal of the presented article is to show that the type of rationality proper to the method of the contemporary sciences yields a unique conceptual environment in which the spirit of rationality instilled to the theological thought by its encounter with the Greek philosophy finds its natural expansion. At the outset, the origins of the Greek rationality in the Ionian school of philosophy are briefly discussed in order to illuminate their adequacy for the exposition and defense of doctrine in the times of the early Church Fathers. Next, the specificity of the scholastic method of St. Thomas Aquinas briefly surveyed to indicate the nature of the unique harmony between faith and reason achieved by the Angelic Doctor. In the following step, the role of rationality in theology is gleaned through negative examples of its elimination as evident in nominalism and the subsequent Lutheran intervention. This is followed by a short discourse into of the origins and the specificity of the contemporary scientific method with particular emphasis on the method’s unique potential to expand and deepen the Greek rationality. Finally, a case study of the evolutionary theology is offered in which the implementation of the dynamic (evolutionary) picture of the Universe as the conceptual foundation opens up new and profound ways of understanding the Universe’s meaning and the meaning of man in particular. Thus the spirit of the hellenistic rationality in theology is not only preserved but also significantly enhanced.

The aim of this paper is an investigation of topological algebras with an orthogonal sequence which is total. Closed prime ideals or closed maximal ideals are kernels of multiplicative functionals and the continuous multiplicative functionals are given by the "coefficient functionals". Our main result states that an orthogonal total sequence in a unital Fréchet algebra is already a Schauder basis. Further we consider algebras with a total sequence $(x_n)_{n∈ℕ}$ satisfying $x^2_n=x_n$ and $x_n x_{n+1} = x_{n+1}$ for all n ∈ ℕ.

Opis:
The derivation through exchange of prefixes (DEP) has been acknowledged as an autonomic derivation technique in Polish only in 2003, and first described in 2010. In French linguistics, it is unknown. However, an analysis of semantic and word formation structure confirms its existence. The contrastive research on this derivation technique, extended to the recent (2006-2015) derivatives, will eventually result in its more precise description and a classification of its products. Recognizing the DEP will lead to a rearrangement of the whole word formation system, among other things, because many derivatives thus formed were treated as simply prefixed ones. The comparison of how the DEP functions in non- related languages will bring us closer to an answer to the question: Can the semantic regularities of the DEP and its rules be universal for the indo-European languages?

The aim of this paper is to research, analyse and comparatively assess the real property tax and it´s Aristotelian (in)justice in various jurisdictions based on the stated quartet of hypotheses. Considering the high focus of jurisdictions on both sides of the Atlantic on human rights and democracy, it is highly relevant to pose the question centred around the hypotheses that (i) real property taxation, (ii) determination of basis, (iii) calculation and rate and (iv) use of proceeds of real property tax are (in)compatible with our perception of justice as founded by Aristotle. Various jurisdictions are analysed, while particular attention given to the Czech Republic jurisdiction case study. The research allows to enhance the understanding and appreciation of the real property tax system and offers preliminary suggestions and recommendations for its improvement in order to make it an effective, efficient and just fiscal tool matching the post-modern global society.

Opis:
After offering a brief outline of Cassirer’s fundamental ideas on symbolization, the article looks at its application to psychopathology, e.g. psychosis, a theme not introduced by Cassirer himself. Psychosis is conceived of as a distortion of a fundamental symbolization, a radical metaphor, thus elaborating a version of Cassirer’s own line of thought. Cassirer’s concept of basis phenomena appears to provide a fruitful conceptual scheme in this regard. At the same time, a case is made for the reappraisal of an anthropological brand of psychopathology. It constitutes a qualification of the currently dominant biological psychiatry, offering a legitimate perspective on psychic disorder, albeit a relative one in both cases – a vision in line with Cassirer’s basic assumptions of symbolization.

Opis:
The article presents the validation of two methods for analyzing the aerodynamic properties of the aircraft wing concerning aeroelastic effects. The first method is based on low-cost computational models (Euler-Bernoulli Beam Model and Vortex Lattice Method [VLM]). Its primary objective is to estimate the wing’s deformation early in the design stages and during the automatic optimization process. The second one is a method that uses solutions of unsteady Navier-Stokes equations (URANS). This method suits early design, particularly for unconventional designs or flight conditions exceeding low-fidelity method limits. The coupling of the flow and structural models was done by Radial Basis Functions implemented as a user-defined module in the ANSYS Fluent solver. The structural model has variants for linear and nonlinear wing deformations. Features enhancing applicability for real-life applications, such as the definition of deformable and nondeformable mesh zones with smooth transition between them, have been included in this method. A rectangular wing of a high-altitude long-endurance (HALE) aeroplane, built based on the NACA 0012 profile, was used to validate both methods. The resulting deflections and twists of the wing have been compared with reference data for the linear and nonlinear variants of the model.

Opis:
The possible radical nitration reactions of isooctane fuel with nitromethane propellant, which is generally used as an additive in fuel formulations, were thermodynamically investigated both at room temperature and at a higher temperature of 691.15 K. The temperature of 691.15 K was chosen because it is the auto-ignition temperature of isooctane and nitromethane and has the potential to mimic better engine conditions. The computational calculations were performed at the theoretical level of DFT UB3LYP/cc-pVDZ. Four different nitration reactions and nitrated products were considered and interpreted in detail. The most and the least favorable nitrations were observed at the primary and secondary carbons of isooctane at 691.15 K, respectively. Four of the designated reactions were endothermic at this temperature. The other outcome of this study was that there was a direct relationship between the thermodynamic tendencies of the considered reactions and the ballistic performances (detonation velocities, detonation pressures, and specific impulses) of their nitrated products. The thermodynamic properties of heats of combustion and deflagration temperatures were calculated via empirical formulations based on the stoichiometry and some other structural parameters of the energetic materials. The results for nitromethane and the nitro-isooctane products were examined.
