Abstract

The paper reports the study of the complexation processes in aqueous solution of α-CD and DMSO. Cyclodextrins (CDs) (sometimes called cycloamyloses) are cyclic oligosaccharides formed by glucose units interconnected by α-(1,4) linkages; α-CD is one of three the most common CDs. It consists of six glucopyranose units. The speed of ultrasonic waves has been measured by the resonance method on ResoscanTM System apparatus. Some collateral data, such as density and heat capacity of the system, have also been measured. On the basis of the experimental data the excess adiabatic compressibility was determined. The extremes of the excess adiabatic compressibility function for different mixture compositions allowed us to establish the composition of molecular complexes formed in the solution. The obtained results suggest the formation of the α-CD with DMSO inclusion complexes with chemical stoichiometric ratio value of 1:1.

Abstract

To improve dye retention, there is a concurrent interest in the development and optimization of an alternative and promising method for the dye recovery in aqueous solutions. In this regard, considerable attention was paid to the polyoxometalates (POMs) assisted ultrafi ltration (POMAUF). The aim of the present study is to eliminate toluidine blue (TB) dye by ultrafi ltration membrane using keggin polyoxometalates (POMs) as complexing agents. In the fi rst step, the keggin polyoxometalates K3[PW12O40]∙6H2O(PW12) and K7[PW) were prepared. Then, the obtained powders were characterized by X-ray diffraction and infrared spectroscopies. Afterwards, the removal of toluidine blue (TB) using polyoxometalates assisted ultrafi ltration (POMAUF) was studied. Factors affecting the retention of dye and permeate fl ux such as transmembrane pressure, operating time, polyoxometalates concentration, ionic strength, surfactant and pH were investigated. All results of both compounds have been presented and discussed. The results reveal that the addition of POMs leads to an increase in dye retention from 11 to 95% for the PW 12 and to 98% for the PW . The results of this work have thus suggested the promising enhancement of ultrafi ltration membrane selectivity for the dye removal using new complexing agents such as POMs in place of polyelectrolytes and surfactants.

Abstract

Deposits in the form of seams are most often exploited by means of mechanised longwall systems. Hard coal seams of various thicknesses are mined by plowing and shearer complexes. Both solutions are commonly used in Polish and global mining. Mechanised longwall systems consist of many machines, the most important of which are the mining machine, powered support, armoured face conveyor and beam stage loader. The article is concerned with the failure frequency of longwalls equipped with plow and shearer longwall systems in one of the Polish hard coal mines. The analysis covers a period of 13 months of the mine’s operation, during which 2,589 failures were recorded. It was carried out for all longwalls exploited in that period, i.e. five plow and five shearer ones, operating in six different sections. In the analysed period, these longwalls worked for an average of 150 days, and a total of 1,484 days. The analysis takes into account the basic division of failures used in the mining branch, i.e. mining, electrical and mechanical failures. The plow and shearer complexes were analysed separately, taking into account the failure category for all devices. A comprehensive analysis of the failure rates has revealed that the failure rate of longwalls equipped with plow complexes is noticeably higher than that of shearer ones. Moreover, it has been demonstrated that mining failures are prevalent in the analysis of both the number of failures and the average duration of failures.

Abstract

The never before published paper is one of the last writings of Juliusz Żórawski (1898–1967), professor architect and theoretician of architecture. The notion of limited complexity introduced here relates to individual characteristics of the conceptual abilities of man. Tasks of architecture are based on prognoses, and this brings with it the risk of making errors. The author criticises J. Fourastié’s prognoses related to the Earth’s overpopulation in 3000 AD, which would force building new cities above the ground, contrary to human psychosomatic nature and habitude.

Abstract

This paper is an attempt to explain the concept of emergence of spatial systems. It indicates basic features of this concept, such as: coevolution, selforganization, patterns, sudden changes, hierarchy. The emergence of complex systems is very fruitful approach to the theoretical reconstruction of the processes of space economy. It should be included in the discussion on evolutionary economics and geography. Recently, in both disciplines creative research is carried out on this subject matter.

Abstract

Linguistic materials of uncertain syntactic status in a corpus of blog posts – This article proposes an analysis of some modalities of the interfrastic connection in the linguistic productions of bloggers. In particular, attention is focused on cases that present a structural interest as they fall into an intermediate space between autonomy and syntactic-semantic integration. More specifically, it focuses on cases of hypercoding and hypocoding of the the syntactic linking of clauses, as well as on cases of deviant coding.

Abstract

The main objective of the research work was to identify the dimensions of complexity and study the relationship between these defined dimensions in the industrial automation sector. To achieve these objectives in the study, there was assumed the following major hypothesis: With the increasing role of dynamic cross-section of the complexity there is growing importance of relationship dimension for competitive advantage. In the study there were diagnosed four dimensions of complexity. Existence of the relationship between these four identified dimensions of complexity occurred by the use of the Fisher’s exact test, which is a variant of the test of independence ��2. Furthermore, there were calculated V-Cramer factors to estimate the intensity of the above-mentioned relationship between analyzed dimensions. The research discovered that the three out of four dimensions such as the number of elements, variety of elements and uncertainty depend on the last dimension of complexity which is the relationship between elements. In the turbulent environment there is a growing importance of the relationship dimension. It forms competitive advantage and is a key condition of success in creating a new type of modern enterprise strategy that occurs within complexity management in the industrial automation sector.

Abstract

The aim of this paper is to analyse various animal-specifi c complex lexical units together with patterns that can be held responsible for their underlying conceptual structure. Many examples of the data investigated in the paper seem to represent compounds as they are traditionally understood in the literature of the subject (see, among others, Bauer 2003; Katamba and Stonham 2006; Lieber and Štekauer 2009; Fàbregas and Scalise 2012; Bauer et al. 2013); however, others do not meet the basic criteria for compoundhood as postulated by, for example, Altakhaineh (2016). In my research I use the term animal-specifi c complex lexical units with reference to all animal-related composite expressions being the result of the working of metaphor-metonymy interaction.

Abstract

This article presents our key arguments about the usefulness of the concept of superdiversity for reimag-ining migration in European societies, based on the example of migration from Poland to the UK. We argue that, despite some criticism of ‘superdiversity’, this concept is beneficial to avoid over-simplifi-cations related to ethno-nationalised homogeneity as the prevailing ascribed feature of Polish migrants, offering a helpful lens through which the complexities and fluidity of contemporary migrant populations and receiving societies may be investigated. Our main point is that such the reimagination might be commenced through applying the concept of superdiversity in research on migrants from Poland in Great Britain. The concept of superdiversity is also beneficial to understand complexities associated with the urban contexts in which migrants settle, their adaptation pathways as well as the intersectional factors shaping migrants’ lives and experiences.

Abstract

In this article the capabilities or mathematical heavy gas atmospheric dispersion models to describe the dispersion or heavy gases in complex and obstructed terrain arc presented. The models have been entegorizcd into three main classes: phenomenological (empirical) models. intermediate (engineering) models and computational fluid dynamic (research) models. Each group or models is discussed separately. The general features or the models arc discussed briefly, Examples of the heavy gas atmospheric dispersion models carable to treat the influence or non-Ilut and obstructed terrain on the heavy gas dispersion result from the work carried out in the European Union and in the US. No model simulating the heavy gas atmospheric dispersion over complex or obstructed terrain has been yet developed in Poland. The need lor future work on the effects of complex and obstructed terrain on the heavy gas atmospheric dispersion is expressed. future research in the area should include both experimental and modeling work. In the context of this raper future modeling work is worth considering in more detail. il seems that all the approaches 10 describe the hcavv gas atmospheric dispersion over complex and obstructed terrain arc worth further aucntion. This opinion is supported by the fact that these approaches arc used in different types of heavy gas dispersion models. which in turn differ in applications. The simpler methods arc introduced to the simpler heavy gas atmospheric dispersion models applied mainly in the routine calculations. The advanced techniques capable to describe the: now near complicated geometrics are used in the sophisticated models applied mainly as a research tools.

Abstract

Complex gaps may be formed when carrying out live working in substations, while the discharge characteristics of complex gaps are different from those of single gaps. This paper focuses on the prediction of critical 50% positive switching impulse breakdown voltage ( U 50–crit + of phase-to-phase complex gaps formed in 220 kV substations. Firstly, several electric field features were defined on the shortest discharge path of the complex gap to reflect the electric field distribution. Then support vector machine (SVM) prediction models were established according to the connection between electric field distribution and breakdown voltage. Finally, the U 50–crit¸+ data of the complex gap were obtained through twice electric field calculations and predictions. The prediction results show that the minimum U 50–crit + of phase-to-phase complex gaps is 1147 kV, and the critical position is 0.9 m away from the high voltage conductor, accounting for 27% of the whole gap. Both critical position and voltage are in good agreement with the values provided in IEC 61472.

Abstract

The awareness of the growing importance of the complexity in creating a new type of a modern enterprise strategy and in introducing changes within planning, control and organizational structures contributed to undertaking studies on relationships occurring between the complexity of a modern enterprise and its flexibility in the sector of industrial automation, as well as filling the gap relating to the cognitive impact of poor complexity management on the flexibility of the company. The main objective of the research work is to check whether there is an important relationship between the complexity of the business and its flexibility in the industrial automation sector. Quantification of the relationship between these two quantities – the complexity and flexibility – happened by the use of the Multidimensional Correspondence Analysis (MCA) and Perceptual Maps. The study which has been carried out indicated that the flexibility and complexity functions in the enterprise management rise, however, the knowledge of these issues is highly insufficient. The research discovered that the obstacles which hamper striking a balance between the flexibility and complexity in their advanced stages exert a devastating impact on the quality of the process management. Reducing the flexibility at its higher levels generates a context in which the market risk is enhanced. Companies characterised by improper flexibility management bear higher workforce costs and their processes of decision-making last longer. Methodical and systematized study of flexibility and complexity will decrease the destructive influence of the interaction between these two categories.

Abstract

In this work, the spectrophotometric studies on the kinetics of redox reaction between gold(III) bromide complexes and sodium nitrite, were carried out. From the kinetic curves collected under different conditions of reactants concentration, addition of bromide ions, temperature, pH and ionic strength, corresponding rate constants have been determined. The obtained results suggest the complex path of the [AuBr4]– reduction consisting of two parallel, bimolecular reactions where different reductant species (HNO2 and NO2–) take place and consecutive step with the metallic gold production. The second-order rate constants at 20oC are equal to 2.948 and 0.191 M–1·s–1, respectively. The values of activation enthalpy and activation entropy for the first and the second parallel step of the reaction were found to be ΔH‡ = 29.18 kJ·mol–1 and ΔS‡ = –13.95 J·mol–1·K, and ΔH‡ = 40.75 kJ·mol–1 and ΔS‡ = –31.06 ­J·mol–1·K, respectively. It was found that the reaction accelerates significantly with the increase of pH and is inhibited with the increase of Br– concentration. The substitutive, inner-sphere mechanism of electron transfer in the studied system was also suggested.

Abstract

The green logistics item as a part of distribution processes represents an innovative perspective in many views. This perspective is current from an offer and demand point of view. Many authors examine only the businesses aspect, while labour market acceptance is important. The aim of this article is to create and verify a green distribution model and this examines the green distribution perception from the consumer’s point of view in a context of chosen demographic characteristics. The creation of a green distribution model is supported by secondary research at which consists of four parts – input, transport, production and sale. Model verification was taken with primary research which base was created of 409 respondents. In the study, we use many statistical and mathematical, as well as scientific and philosophical methods. Among the most significant belong Cronbach’s alpha and McDonald’s omega. We used to verify and estimate model reliability, correlation analysis for relation research, one-way ANOVA test for research hypotheses verification and cluster analysis for identification of possible hidden clusters. The model can be considered a reliable one. Results indicate a low influence of distribution ecological factor in a consumer’s perspective, as well, it can be stated, the age, contrary to sex, represents a significant factor in a green distribution perception. Results can be used in both the academic and commercial spheres in various fields and disciplines. The primary survey was conducted in Slovakia, but it would be appropriate to examine the model in other countries, as well as to identify factors that may affect the model of green distribution in the future.

Abstract

The paper presents the meaning of complexity as a notion in psychology, and its influence on architectural theory in the 1960s, focusing on the notion of optimal complexity. A commentary is presented on the two texts („Network of straight lines” and „Limited complexity”) by professor architect Juliusz Żórawski from 1967, where he has introduced the term of limited complexity in relation to architecture, and where he criticizes excessively far reaching forecasts of future development. Żórawski’s concepts are parallel to those of R. Venturi at that time.

Abstract

Most of the medieval Italian cities are civitas born of the ruins of the ancient Roman civilization. Their beauty ist the origin for deep esthetical experiences, to which Sławomir Gzell gave the name bellezza. There are a few characteristic features composing the "picturesqueness", painterliness and harmony of those cities, which lead the observer to strong emotions and constant, sensual exploration. The author contemplates the aspects creating the phenomrnon of beauty of Italian cities and towns - which are the metapfor of human desires and deepest cravings.

Abstract

The article reveals the problems of the formation and implementation of Ukraine’s energy policy

from the beginning of its independence to the present day. The specificities of the fuel and energy

sector of the country’s economy, the main stages of formation, macroeconomic conditions and the

problems of its transformation were analyzed. The slow and contradictory processes of reforming

Ukraine’s fuel and energy complex throughout the period of its independence and the fact that the

inconsistency with the main directions of the economic policy did not ensure its effective transformation

have been proven. The results of the OECD assessment of progress towards the main

objectives implementation of the Ukraine’s Energy Strategy have been presented. It was noted that

the results of the research suggest that the progress in achieving the goals of Ukraine’s Energy Strategy

is ambiguous, therefore the strategy needs to be refined accordingly. There are two main factors

moving away from the formal and declarative nature of Ukraine’s energy policy to its realistic model.

Firstly – an international factor associated with Ukraine’s extending involvement in international cooperation

within the energy sector, Ukraine’s international commitments to reform the energy sector

towards increasing energy efficiency, green energy, etc. Another – the crisis factor – as a result of the

energy policy of the Russian Federation. It was noted that the role of these factors in the future will

remain determining. The need to improve Ukraine’s energy policy, taking the current trends in the

development of the world energy system, new challenges and threats to politico-military and energy

confrontation with the Russian Federation into account, has been proven.

Abstract

The aim of this study was to examine whether there are differences in the performance on simple and complex mathematical tasks depending on the personality traits and the presence of an audience. After completing the personality questionnaire, within the first experimental session, participants (N=70) solved one set of simple and one set of complex mathematical tasks. In the second session participants solved another set of simple and another set of complex tasks. In one of the sessions, participants were solving tasks in front of the audience, while in the other session the audience was absent. The results indicate that presence of an audience facilitates performance of those participants low on neuroticism, but only when they are solving simple tasks.

Abstract

The paper is devoted to the control of operability of Peltier modules based on the analysis of transient modes of their operation. Advantages of using low-power thermoelectric modules for the development of thermoelectric plants with adaptive control systems for the needs of the agricultural complex, which significantly reduce their cost characteristics, are shown. The problem of using the stationary mode of their operation, associated with the low efficiency of the modules, as well as the dynamic mode, associated with the presence of transient processes, is indicated. It is noted that overcoming this problem requires solution of the task of automation of reliability providing the well-known approaches to its solution are shown, for which the key advantages and disadvantages are given. An approach is proposed to complex control of the operability and quality of thermoelectric modules during their expluatation in three components of the physical process of thermoelectric conversion (Peltier thermoelectric effect, electrical and thermal transfer phenomena) by analyzing transients in the system based on identification algorithms. To justify it, the necessary equations and mathematical relations are given. Aprobating of the proposed approach was carried out experimentally by determining the time constants for operable and defective commercially available modules and showed its significant advantages over the standard verification procedure.
