Opis:
"Local development is a process of positive qualitative and quantitative changes occurring in a given system, taking into account the appropriate needs, preferences and values". This definition, proposed by L. Wojtasiewicz (1997), allows to fully capture the phenomenon of obliterating the boundaries between the sphere of economy and that of culture, which many authors think to be characteristic of the contemporary times. Interest in this form of tourism is reflected, among others, in the growing number of various programmes and initiatives fostering the development and creation of new tourist products. This can be observed at all levels, from the local to the supra national level. This issue has a well-established presence in the regional policies of the European Union, which ever since the beginning of the PHARE programme has had a considerable influence on the strategy of tourism development in Poland. In the EU, this branch of the economy is regarded as an important tool of stimulating regional development. As a result of the awareness of the current trends, growing competition of non-European countries and the expanding European market (owing to the ageing of the society), more and more activities are undertaken in the sphere of broadly understood cultural tourism. However, creating a quality product in this sphere requires a very thorough understanding of both the resources and the needs, and an assessment of the threats to the cultural heritage which, according to the contemporary definition, comprises not only lasting material elements, but also much more sensitive non-material aspects, such as language or tradition. In every instance, the creation of a cultural tourism product should be preceded by a thorough assessment of the resources and market needs. Frequently, the successors themselves are not aware of the wealth of their cultural heritage. The idea to address promotion to tourists and to the local communities seems well founded (Kneafsey, 2000). At the same time, it should be borne in mind that ignorance might not only preclude the use of a given resource, but also lead to its destruction in connection with another activity.

Opis:
Niekontrolowane rozprzestrzenianie się zabudowy niewątpliwie stanowi zagrożenie dla rozwoju i ciągłości miast, a także dla zachowania ładu przestrzennego. Wielopłaszczyznowość suburbanizacji uzależniona jest od różnorakich czynników ją determinujących, np. natury społecznej, ekonomicznej, kulturalnej i środowiskowej jak również politycznej czy prawnej. Biorąc pod uwagę czynniki jak również formy jakie przybiera należy zauważyć jak bardzo ten proces jest złożony i skomplikowany.
The uncontrolled spread of building certainly is a threat to the development and continuity of the cities, and also for spatial behavior. Multilevel nature of suburbanisation depends on many factors which determine it, eg. social, economic, cultural and environmental as well as political or legal. Considering factors and forms of suburbanisation to be noted how much this process is complex and complicated.

Opis:
We investigate multi-server queueing systems with Poisson arrivals, non-identical servers and customers of random volume, under assumption that customer’s service time having an exponential distribution doesn’t depend on his volume, but service time parameters can be different for different servers. We also assume that the total volume of customers present in the system at arbitrary time instant is bounded by some constant value V > 0. For such systems the stationary customers number distribution and loss probability are determined.

Opis:
Głównym założeniem pracy było stworzenie dogodnych warunków dla rozwijającej się, w sposób niekontrolowany, wsi Przęsocin. Dla uniknięcia tak spontanicznego procesu suburbanizacji niezbędna jest eskalacja świadomości samorządów, projektantów jak również przedsiębiorców budowlanych dotycząca prawidłowego zagospodarowania przestrzennego. W oparciu o istniejące dokumenty oraz przyjęte wnioski z przeprowadzonych analiz podjęto decyzje planistyczne sprzyjające tworzeniu wysokiej jakości środowiska zamieszkania. Wytyczną projektu było stworzenie przestrzeni przyjaznej mieszkańcom osiedla. Projektowanie zabudowy mieszkaniowej odpowiadającej wymogom inwestora, pragnącego maksymalnie wykorzystać teren przeznaczony pod zabudowę (za czym idzie większy zysk) jest karygodne i niedopuszczalne. Niestety, większość projektów zagospodarowania sporządzana jest "na kolanie" bez poszanowania zasad kompozycji urbanistycznej oraz potrzeb mieszkańców.

Opis:
M/M/n/(m,V) queueing systems with service time independent of customer volume are well known models used in computer science. In real computer systems (computer networks etc.) we often deal with the overload problem. In computer networks we solve the problem using AQM techniques, which are connected with introducing some accepting function that lets us reject in random way some part of the arriving customers. It causes reduction of each customer's mean waiting time and let us avoid jams in consequence. Unfortunately, in this way the loss probability increases. In this paper we investigate the analogous model based on some generalization of M/M/n/(m,V) queueing system. We obtain formulas for a stationary number of customers distribution function and loss probability and we do some computations in special cases.

Opis:
We study a shape optimization problem for a paper machine headbox which distributes a mixture of water and wood fibers in the paper manufacturing process. The aim is to find a shape which a priori ensures the given velocity profile on the outlet part. The mathematical formulation leads to an optimal control problem in which the control variable is the shape of the domain representing the header, the state problem is represented by the generalised Navier-Stokes system with nontrivial boundary conditions. The objective of this paper is to prove the existence of an optimal shape.

Opis:
Co-based alloys represent very important group of materials used for medical applications. Currently, fabrication of these materials is preferentially done by casting or forming. Production by powder metallurgy techniques is less common. However, powder metallurgy fabrication of these alloys brings advantages such as reduced machining, possibility of alloying by high-melting elements, preparation of nanocrystalline materials with enhanced mechanical properties or producing of porous alloys with improved ability to integrate into issues. In this work, our attention was focused on fundamental preparation of an CoCrMo alloy by two methods of powder metallurgy. In the first method, pure metallic powders were mixed, pressed and sintered in vacuum furnace. The second applied technology consisted of mechanical alloying using planetary ball mill and compaction by spark plasma sintering technique. A series of samples was prepared under various conditions by these procedures. Dependence of microstructure, phase composition and mechanical properties of prepared samples on fabrication conditions (milling parameters, sintering temperature etc.) was studied. Obtained results were compared with properties of commercial cast cobalt alloy used for medical applications.

Opis:
The paper presents results of sintering proppants parameters and its influence on light ceramic proppants obtained by the mechanical granulation method. The proppants were prepared basing on a ceramic composition consisting of three raw materials such as kaolin, clay and bauxite mixed with poly(vinyl alcohol) binder with a molecular weight 26000 g/mol and hydrolysis degree of 88%, added in amount of 5 wt% with respect to the powder. Sintering temperature range oscillated between 1200 and 1225°C, kiln rotations were 1-2 rpm. Sintered proppants were characterized in compliance with PN-EN ISO 13503-2 norm and bulk density, sphericity coefficient, turbidity, solubility in acids and scanning electron microscopy observations have been estimated. The results demonstrated that sintering temperature and kiln rotation have an essential effect of the proppants parameters.

Opis:
The investigation of fabricated ceramic materials, which can be used as proppants, is presented. Proppants are ceramic materials applied in hydraulic fracturing during extraction of shale gas. Solid slurry pumped with liquid into the deposit causes destruction of the rock structure. The role of proppants is to avoid closing of formed pores and as result enable gas migration from the deposit. Due to processing requirements and conditions in formations (high pressure and temperature), proppants should be characterized by proper physico-mechanical properties. The aim of this work was to elaborate the preparation method of ceramic materials, which can be used as proppants. In this paper results of properties studies of obtained proppants are presented. The influence of raw materials composition, especially the type of applied binder, was examined. Two types of green proppants obtained by the method of mechanical granulation without binder and with poly(vinyl alcohol) in amount of 5 wt% with respect to the powder were used. The properties: bulk density, roundness and sphericity coefficient, grain size and also structure and morphology of proppants was determined by the method of scanning electron microscopy with energy dispersive spectroscopy. The results indicate that composition of raw materials and type of binder have an important influence on the properties of obtained proppants in green state.

Opis:
In this work technological properties of ceramic slurries based on silicon carbide powder with solid content 70 wt% were presented. These slurries were prepared for obtaining shell moulds in precision casting of Ni superalloys engine parts. The main binder was dispersion containing nanoalumina particles. Additionally poly(vinyl alcohol) with molecular weight 26000 g/mol as 5 wt% water solution was used as a rheological modifier. To characterize silicon carbide: scanning electron microscopy images, chemical composition, Zeta potential and grain size were studied. Technological properties of ceramic slurries i.e.: plate weight test, viscosity, dynamic viscosity, density and pH were investigated. Properties of silicon carbide based ceramic slurries are very promising and their shell moulds are very perspective for future application in aerospace industry.

Opis:
This paper examines the relationship between business environment, competitiveness and firm performance considering a survey data from three consecutive years: 2013-2015. The comparative analysis showed that over these years business environment, competitiveness and firm performance of Finnish SMEs are slowly deteriorating. Results from correlation analysis revealed that business environment, competitiveness and firm performance are positively correlated. However, the relationships between these variables are not consistent in respect to competitive priorities indicating a dynamic nature of cost, quality, time, and flexibility dimensions. Besides these findings our analysis acknowledged that to improve firm performance, irrespective to the choice of competitive priority, SMEs should pay more attention to their competitiveness rather than blaming the business environment. The paper concludes that simultaneous use of competitive priority dimensions might be more favorable as a source of competitiveness and competitive advantage to improve firm performance. However, the managers are encouraged to compare the results, findings and concepts presented in this paper among themselves and comprehend the specific answer to the question posed in the title.
