Opis:
In multi-tier distribution, in addition to suppliers and consumers there are also intermediaries who participate in the transfer of products from manufacturers to end consumers. The choice of the distribution system depends on the optimisation of the performance indicators for servicing an area, taking into account the technical capabilities of the individual logistics chain links. The paper compares two typical distribution structures in the construction sector. The choice of the structure is a function of the manufacturer’s economic and organisational determinants. The paper presents a model representing the costs of two typical distribution structures in the construction sector. The choice of the structure depends on the company’s outsourcing policy and total costs of all three major system components: the distribution network, transport network, and warehousing. Rationally built and implemented functioning models are a key element of business success in the marketplace. The choice of a suitable strategy is difficult, as it depends on many dynamically changing parameters which directly affect costs. In addition, the relations between the system elements are very complex and interdependent.

Opis:
W celu sprawdzenia oddziaływania podłoża na stan naprężenia powstający w konstrukcji, a tym samym sprawdzenia możliwości bezpiecznego przejęcia prognozowanych wpływów eksploatacji górniczej przez konstrukcję budynku przeprowadzona została numeryczna analiza obliczeniowa. W pracy rozważono 4 różne rodzaje gruntów powszechnie występujące na terenie Górnego Śląska, dla których otrzymano różne wartości sił generowanych przez wpływy górnicze na fundamenty i ściany pionowe zagłębione w podłożu górniczym wybranego budynku. Przeprowadzona w ujęciu inżynierskim analiza wskazuje na wpływ rodzaju gruntu na rozkład naprężenia w konstrukcji, wykonanej w technologii tradycyjnej, który może świadczyć o możliwości powstania uszkodzeń w określonych miejscach.
Mining exploitation influences on the surface. In order to verify the possibility of safe inflows acquisition by the structure of the building a numerical analysis was performed. Cooperation with the ground mining structure depends on the type and parameters of the soils. This study analyzes four different types of soil commonly found in Upper Silesia. For each soil a different value of forces generated by the influence of mining on the foundations and walls embedded in the surface of selected buildings was obtained. The analysis indicates the impact of soil type on stress distribution in structures, which may factor in the possibility of causing damage in selected places.

Opis:
This data article aimed to evaluate the influencing mechanisms of the nutrients and the level of eutrophication in the Yangtze River estuary. The seasonal characteristics of nutrients (dissolved inorganic nitrogen (DIN), SiO3-2–Si, and PO43-P) in the seawater of the Yangtze River estuary were analyzed by conducting surveys in spring and summer of 2019. The findings revealed that the concentrations of all nutrient at the surface and bottom layers were lower in spring compared to summer. NO3–N was typically the major form of DIN. Runoff was identified as the primary source of DIN and SiO32−–Si, while PO43−–P originated from a various sources. The SiO32−–Si, while PO43−–P values in the surface and bottom layers during the spring and summer were higher than the Redfield values, indicating an imbalanced nutrient distribution. Furthermore, discrepancies were observed in the distributions of DIN/PO43−–P, SiO32−–Si/DIN, and SiO32−–Si/PO43−–P in the Yangtze River estuary. Through an examination of the ratio of DIN/PO43−–P absorbed by phytoplankton, PO43−–P was identified as a potential limiting factor for nutrition in the sea area of the Yangtze River estuary during spring and summer. The Eutrophication Index (E) values for both spring and summer were found to be higher than the eutrophication threshold, indicating severe eutrophication in the studied sea area.

Opis:
At present fish processing industry is one of the most dynamically developing groups belonging to food industry in Poland. In the last ten years the sold production of fish processing industry increased over three times. Fish processing companies reveal a great ability to adapt to turbulently changing conditions of the market game. It happens this way, among others, as a result of creating competitiveness by widely understood consolidation processes and creating strong organizational and spatial ties of an international range. At the same time European market of fish processing guaranteed not only economic standards for already existing companies, but also became an impulse for creating new production units offering their products and services in the European Union market. The article attempts to determine the weight of factors and advantages of location for fish processing industry in Poland and their influence on the changes in the spatial structure. Besides the changes in distribution, the food processing companies in Poland were also characterized taking into consideration their concentrationin view of the theory of cluster.

Opis:
Artykuł rozpoczyna cykl publikacji poświęconych opisaniu procesów modernizacyjnych zachodzących w XIX wieku na obszarach położonych na wschód od Wisły. Jego celem jest przedstawienie stanu, rozmieszczenia i struktury demograficznej populacji wiejskiej (chłopi i drobna szlachta) parafii Trzcianne u schyłku I połowy XIX wieku, położonej peryferyjnie w stosunku do przemian zachodzących w Europie. Podstawą źródłową analiz stanowi rękopiśmienny spis mieszkańców parafii z 1843 roku. Badana populacja charakteryzowała się reprodukcją rozszerzoną i niskimi rozmiarami celibatu definitywnego. Dla obu podstawowych grup społecznych mieszkańców parafii, chłopów i drobnej szlachty, szybkie założenie rodziny było nadrzędnym celem.
The article initiates a publishing cycle devoted to the description of modernising processes taking place in the 19th century in the areas east of the Vistula River. The publications are intended to present the state, distribution and demographic structure of the rural population (peasants and the lower layers of the gentry) living within the parish of Trzcianne at the end of the first half of the 19th century; the parish was situated peripherally in relation to the changes taking place in Europe. A handwritten list of the inhabitants of the parish, dated 1843, is the main source. The features of the population under research were its extended reproduction and a tiny size of definite celibacy. The main goal of both basic social groups – peasants and petty gentry – was to found a family as soon as possible.

Opis:
The problem of impact pressure distribution on a monopole structure excited by irregular breaking waves is investigated. The analysis is performed by applying a numerical model that combines potential flow model with a Navier-Stokes/VOF solution. The temporal pressure distribution is analysed for two breaking wave cases characterized by the significant difference in the steepness of the wave front. The peak impact pressures are observed in the region below the overturning wave jet where the pressure increases rapidly resulting in a peak value of the slamming coefficient equal to Cs=2π. The vertical load distribution provided by the derived model is more realistic than a rectangular shape distribution applied in engineering practice. This is because the vertical load distribution strongly depends on breaking wave shape and it is difficult to uniquely approximate such a load distribution by a rectangle.

Opis:
The article presents trends of change in Warsaw's economic structure and their influence upon the formation of the city's functional and spatial structure. Using the latest data on the employment structure and kinds of economic entities and their distribution, an attempt has also been made to determine the degree of absorption of the city economy by pro-development activities. On the basis of experiences of other European cities activity types indicating the existence of development trends in the city economy (pro-development activities) were chosen. Next, changes in the number of economic entities in these areas in 1988-2004 were analyzed. Research on the distribution of economic entities in Warsaw is based upon data from the REGON register.

Opis:
Nucleoside transporters (NT) facilitate the movement of nucleosides and nucleobases across cell membranes. NT-mediated transport is vital for the synthesis of nucleic acids in cells that lack de novo purine synthesis. Some nucleosides display biological activity and act as signalling molecules. For example, adenosine exerts a potent action on many physiological processes including vasodilatation, hormone and neurotransmitter release, platelet aggregation, and lipolysis. Therefore, carrier-mediated transport of this nucleoside plays an important role in modulating cell function, because the efficiency of the transport processes determines adenosine availability to its receptors or to metabolizing enzymes. Nucleoside transporters are also key elements in anticancer and antiviral therapy with the use of nucleoside analogues. Mammalian cells possess two major nucleoside transporter families: equilibrative (ENT) and concentrative (CNT) Na+-dependent ones. This review characterizes gene loci, substrate specificity, tissue distribution, membrane topology and structure of ENT and CNT proteins. Regulation of nucleoside transporters by various factors is also presented.

Opis:
The ciliate Mesodinium rubrum Lohmann 1908 (= Myrionecta rubra Jankowski 1976) is an important phototrophic organismin the Gdańsk Basin. In June 2002 the vertical distribution and size structure of the M. rubrum population were studied. Its presence was generally observed in the whole water column (one exception was the anoxic near-bottom zone in the Gdańsk Deep) at all stations studied. Maximum abundance (18 300 cells dm−3) was recorded at 26 m depth at the station located in the inner Gulf of Gdańsk. Analysis of the size structure of the counted organisms demonstrated the co-existence of small and large cells of M. rubrum in the upper layer of the water column and a gradual increase with depth of the prevalence of large specimens. This shows that at least two forms of M. rubrum exist in the region studied. Deep migrations are probably undertaken only by relatively large organisms.

Opis:
Urban medium voltage (MV) electric power distribution networks are supplied with primary (HV/MV) substations. These networks supply secondary (MV/LV) transformer substations and are often built as closed structures - loop arrangements. The design problem of optimal urban MV distribution network structure consists of determining the number of primary substations, establishing the number of MV loops supplied with the primary substations, and assigning the secondary MV/LV transformer substations to the MV loops. The optimization task becomes especially complex when the number of the primary substations is greater than one. The minimum of total annual costs is sought. The total annual costs include: fixed (investment) costs, variable (operating) costs and supply-interruption costs. Typical constraints are also accounted for. The so defined optimization problem is a complicated mathematical problem in respect of computational effort. In order to resolve the mathematical model of the optimization problem, evolutionary algorithms and artificial neural networks have been used. Exemplary computational experiments have been executed on the model of urban MV multi-loop electric power distribution networks. The results from the evolutionary algorithm and the artificial neural network calculations have been compared.

Opis:
The Matthew effect, considered in the broad context of a whole society, implies that increasing social inequality results from the accumulation of advantages provided by wealth and by the amassing of disadvantages associated with poverty. We formulate a hypothesis according to which the Matthew effect manifests itself in the polarization of opposite social classes even if the adaptive abilities of people belonging to different classes are controlled. The test of this hypothesis is primarily based on data drawn from the Polish Panel Survey (POLPAN), a survey in which respondents from a national sample were interviewed in 1988, 1993, 1998, and 2003. Additional data were obtained from surveys conducted in 1978 and 2006. All these data show that (a) during the last decade of the communist regime in Poland, the level of income inequality was relatively low and stable; (b) the change in the class structure occurring between 1989 and 1993 resulted in the rapid growth of social inequality, and (c) inequality increased up to 2006. The hypothesis stating that income inequality is rooted in the class structure, independently of people’s adaptive abilities, is fully supported. Theoretical and practical implications of results supporting our hypothesis are also discussed.
