Opis:
Social segregation is a subject common in contemporary studies of metropolitan areas. Until recently, studies of segregation focused on the distribution of ethnic groups, immigrants, and the poor. Today, they also cover additional indicators such as demographic properties, education, and affiliation with social and professional categories, which can also serve to determine the causes of the segregation (including the selfsegregation of the rich). This article aims to point out the measures of segregation that present the segregation levels in the most complete manner, along with their application in the context of three European metropolitan areas: Warsaw, Berlin, and Paris. The first part of the article is a review of the existing approaches to segregation measures, followed by the selection of research method, presentation of the analysis' results, and evaluation of the applied methods; presenting the opportunities and limitations in research of the social segregation phenomenon.

W przemyśle spożywczym często stosujemy materiały sypkie (ziarna zbóż, produkty ich przemiału, cukier, dodatki smakowe, granulaty itp.). Operowanie materiałami ziarnistymi jest trudne. Mimo licznych badań zrozumienie ich zachowania się jest nadal niedostateczne. Prowadzonym operacjom stale towarzyszy segregacja utrudniająca właściwe przetwarzanie. Poznanie jej mechanizmów staje się koniecznością. Omówiono istotę segregacji i podstawowe jej mechanizmy. Wiedza ta jest niezbędna do świadomego wpływania na zachowanie się zróżnicowanego materiału sypkiego.
Segregation appears on processing granular materials. The mechanisms of segregation were presented. Reasons of segregation and her conditioning were published. These facts permit to take a decision consciously aiming to minimalizing segregation working.

Warsaw Metropolitan Area
Opis:
Warsaw and its metropolitan area seem an interesting testing ground for research on the phenomenon of residential segregation in the context of the evolution of housing policy, since the city has been subject to significant changes as a result of historical events. Each of these contributed to alterations in the level and the character of residential segregation. The goal of this article is to answer the following question: Was the changing housing policy in Warsaw and the surrounding metropolitan area during the transformation period and afterwards accompanied by a modification of the segregation structure and what differences can be noticed in the whole of the metropolitan area and in the city itself?

Opis:
Although the socio-spatial aspect of cities in the globalisation era has gained a new dimension, it cannot be explained by the globalisation process alone. The article presents the problem of social and ethnic segregation in Île-de-France between 1999 and 2009. Socio-economic and demographic data are used to measure indices of segregation and the description of characteristic chosen districts to show its spatial inertia. The analysis revealed a higher degree of social segregation in the entire Paris metropolitan region than in the city of Paris itself. The upper class is the most segregated group, followed by foreigners, immigrants and the lower class. The pattern emphasises the important role of autosegregation factors and functions. It is observed that a constant division into homogenous parts exists in the prestigious and affluent western districts and the impoverished immigrant north-eastern districts. Socio-spatial tendencies reveal the growing importance of the upper class.

Opis:
The aim of this article is to answer two questions concerning the scale and the pattern of residential segregation in Warsaw at the local level and the character of contemporary processes accompanying and modifying this phenomenon. While examining residential segregation we have applied a multidimensional approach to underline the complex nature of this phenomenon. We have focused on data concerning different demographic and socio-economic categories. Furthermore we indicate and describe three socio-spatial, contemporary processes that have accompanied an increase in social inequalities in Warsaw (the creation of enclaves of poverty and wealth and the process of gentrification). The research reveals increasing social inequalities at the local level that began in the socialist era and have strengthened during the transformation period, as well as the stability of the socio-spatial pattern in selected districts that influence their local specifics.

This article presents research results concerning designation of the scope of segregation of elements by analysing the ingot, designated for hot rolling of long products. The research tests were performed under industrial conditions, during continuous casting production cycle of high carbon steels. From cc ingots with square cross-section of 160 mm samples having the length of 400 mm were collected, out of which two samples were cut up, the so-called templates with the thickness of 20 mm. Segregation of elements was determined based on the quantitative analysis of results performed by using spark spectrometry pursuant to PN-H-04045. Changes in concentrations of elements were analysed along the line, which join the opposite sides of the sample in their half length and pass through the geometric centre of the square cross-section. In the further course of the research study, there was also determined the segregation along perpendicular line up to the surface connecting the core of the cross-section with lateral plane. Designations of element contents were performed at points distanced from each other by approx. 10 mm and situated on the lines. There was found segregation of carbon, sulphur and phosphorus.

Opis:
Over the past few decades, school choice has been a widely debated issue around the globe, following the development of pluralism, liberty, and democracy. In many countries, school choice systems were preceded by residence-based school assignment systems, creating a strong connection between a neighborhood and its schools’ demographic compositions. However, schools often remain highly segregated. School segregation is thus seen as a major problem and is supposedly driven by three main factors: residential segregation, parental school choice, and schools’ selection of pupils. This paper aims to shed light on what research should be focusing on as regards school choice and residential segregation with the following two research questions: What are the links between neighborhood and school choice in the literature? How are neighborhood and school choice connected to school segregation in the literature? Two main findings emerged: (1) the neighborhood-based social networks that parents developed had limited their school choices and (2) neighborhood segregation is one of the most important factors that contributes to school segregation and is related to multi-ethnic and socioeconomic contexts.

Opis:
Wielkie osiedla mieszkaniowe (WOM) projektowano jako wyodrębnione jednostki urbanistyczne, bez kontynuacji funkcji iejskich lub wielkomiejskich. Po 1989 r. zaszły w nich zmiany związane z transformacją gospodarczą. Z perspektywy 20 lat widać, że wiele osiedli nie zostało jednak włączonych do funkcjonalnej struktury miasta i nie nabrało cech miejskich. W opracowaniu przedstawiono wyniki analizy dzielnic Warszawy o wysokim udziale WOM – Targówka i Ursynowa. Płynie z niej wniosek, że jednym z najważniejszych elementów rewitalizacji osiedli jest tworzenie powiązań między osiedlami a miastem, w szczególności centrum. Takie działania powinny prowadzić do zmniejszenia stygmatyzacji mieszkańców, wprowadzania funkcji o znaczeniu ponadlokalnym, sprzyjać istnieniu zróżnicowanych grup mieszkańców. Pomocne dla rewitalizacji jest określenie celów z uwzględnieniem całościowych planów rozwoju miasta. ednostki sąsiedzkie z centrami lokalnymi mogą stanowić korzystne rozwiązanie, ale wyraźne wyodrębnienie osiedli zwiększa ryzyko przestrzennej segregacji społecznej. Utrudnia też wykorzystanie mocnych stron i szans rozwoju, jakie pojawiają się w całym mieście. Dlatego działania, o których była mowa wyżej, mogą wzmacniać pozytywne skutki rewitalizacji, a także apobiegać jej potrzebie na przyszłość.
Large housing estates were designed from the beginning as separate entities, not as a continuation of previous urban structure of a city. After 1989, the economic transformations caused a lot of changes within the cities. However, even after more then 20 years, we can observe that many estates have not been included within urban structures and they lack urban character. In this paper, we present two Warsaw districts, Targówek and Ursynów, where the majority of inhabitants live in large housing estates. The results of our analysis show the significance of the relationship between the districts and the ther parts of the city, especially its downtown area. Actions should be taken to reduce the stigma of living in an estate, introduce extra-local functions and attract diverse social groups. One of the important reasons of the degradation of large housing estates are the unseen borders – social and functional ones – between them and the rest of the city. Neighbourhood units, with their local centres, can create lively and healthy areas, yet the units with no relation to the surroundings bring the risk of social and spatial segregation. Disintegration can also become an obstacle in bringing all city's assets into play. Creating the net of relationships between the large estates and the city can make their regeneration less needed and more successful at the same time.

The effect of ultrasonic vibration on the microstructure, elimination of casting defects and distribution of alloyed elements at macro-scale during solidification of 35CrMo steel has been investigated. Results show that ultrasonic treatment has a significant effect on the grain refinement, especially the fragmentation of the secondary dendritic arms of the studied steel. Density of the casting defects decreases and the alloyed elements are seen more even distribution at macro-scale with the introduction of ultrasonic vibration. Meanwhile, the ultrasonic vibration works more efficiently in the longitudinal direction than in the radial, and its efficiency declines with the distance from the radiator increasing.

Opis:
The segregated nature of urban areas reflects an uneven exposure to risk and unsafety. This article analyzes the relevance of place to people’s feelings of unsafety by comparing questionnaire responses from people living in a segregated, disadvantaged neighbourhood to a random sample of people living in the same city. The results suggest that the central factors explaining the individual’s feelings of unsafety differ in this particular neighbourhood compared to the broader population. The article shows that place has a moderating effect on feelings of unsafety. Trust in public institutions is argued to be particularly important in segregated, disadvantaged neighbourhoods because of its potential to prevent feelings of unsafety.

Jako materiały badawcze wykorzystano cząstki kuliste o różnych gęstościach oraz cząstki niekuliste o różnym kształcie. Materiały badawcze dobrano w taki sposób, aby utworzyć układy dwuskładnikowe, przy stałym komponencie cząstek kulistych w każdym z układów. W celu oceny wpływu gęstości jak i kształtu posłużono się współczynnikiem rozrzutu Co V wyznaczonym dla poszczególnych komponentów mieszaniny z uwzględnieniem zakresu prędkości nośnika transportującego.
Research results dealing with effects of density and particle shape on the two-component system segregation phenomenon in an air separator are presented in the paper. Spherical particles of different densities and non-spherical particles of different shapes were used as research material. Materials were chosen to create two-component systems with a constant spherical particles' component in each of them. In order to assess the effect of density and shape, the spreading factor CoV determined for individual mixture components including the transporting agent speed range was used.

Opis:
INTRODUCTION: In the face of sudden events with many victims, various types of medical segregation systems were created. Their aim is to set the treatment and transport priority of patients by giving them appropriate urgency codes considering their general condition and vital parameters. The study is aimed at comparing the effectiveness of selected medical segregation systems. MATERIAL AND METHODS: The research tool consisted of one hundred virtual patients, whose condition was categorized according to the START system (Simple Triage and Rapid Treatment) for four urgency codes - 25 persons for each of four categories. Then they were segregated by assigning the wounded to individual urgency codes using the SIEVE and CAREFLIGHT systems. To the statistical analysis was used the Mann-Whitney U test. All results were considered significant at p <0.05. RESULTS: Among 100 patients using the SIEVE system, 25 were identified in green and black code, 27 in yellow code and 23 in red code. Using the CAREFLIGHT system, 25 patients were shown in green and black code, 31 in yellow code and 19 in red code. There were no differences between segregation systems between green and black code patients (Code 3 and 4: START = 25 vs. SIEVE = 25 vs. CAREFLIGHT = 25). In contrast, the yellow code showed differences in the SIEVE system compared to the control group - START system (p = 0.005, Code 2: START = 25 vs. SIEVE = 18), which, however, was not demonstrated in relation to CAREFLIGHT (Code 2: START = 25 vs. CAREFLIGHT = 25). In the red code showed differences between the control group and the SIEVE system (p = 0.001, Code 1: START = 25 vs SIEVE = 16), and the CAREFLIGHT system (p = 0.010, Code 1: START = 25 vs. CAREFLIGHT = 19). CONCLUSIONS: The effectiveness of selected medical segregation systems (START, SIEVE and CAREFLIGHT) is significantly different among patients in yellow and red code. Taking into account the highest urgency code, the most sensitive selection is shown by the START system, and the least sensitive - CAREFLIGHT.
WSTĘP: W obliczu występowania nagłych zdarzeń z wieloma poszkodowanymi, powstały różnego typu systemy segregacji medycznej. Ich celem jest ustalanie priorytetu leczniczo-transportowego pacjentów poprzez nadanie im odpowiednich kodów pilności biorąc pod uwagę ich stan ogólny oraz parametry życiowe. Przeprowadzone badanie ma na celu porównanie efektywności wybranych systemów segregacji medycznej. MATERIAŁ I METODY: Narzędzie badawcze stanowiło stu wirtualnych pacjentów, których stan został skategoryzowany według systemu START (Simple Triage and Rapid Treatment) na cztery kody pilności -po 25 osób do każdej z czterech kategorii. Następnie poddano ich segregacji przyporządkowując rannych do poszczególnych kodów pilności stosując systemy: SIEVE oraz CAREFLIGHT. Do analizy statystycznej posłużono się testem U Manna-Whitney’a. Wyniki uznano za istotne przy p < 0,05. WYNIKI: Wśród 100 pacjentów przy zastosowaniu systemu SIEVE wyodrębniono po 25 w kodzie zielonym oraz czarnym, 27 w kodzie żółtym oraz 23 w kodzie czerwonym. Korzystając z systemu CAREFLIGHT wykazano po 25 pacjentów w kodzie zielonym i czarnym, 31 w kodzie żółtym oraz 19 w kodzie czerwonym. Między pacjentami w kodzie zielonym i czarnym nie wykazano różnic pomiędzy systemami segregacji (Kod 3 i 4: START = 25 vs. SIEVE = 25 vs. CAREFLIGHT = 25). Natomiast w kodzie żółtym wykazano różnice systemu SIEVE w stosunku do grupy kontrolnej – systemu START (p=0,005; Kod 2: START = 25 vs. SIEVE = 18), której jednak nie wykazano w stosunku do CAREFLIGHT (Kod 2: START = 25 vs. CAREFLIGHT = 25). W kodzie czerwonym wykazano różnice pomiędzy grupą kontrolną oraz systemem SIEVE (p=0,001; Kod 1: START = 25 vs SIEVE = 16), a także systemem CAREFLIGHT (p=0,010; Kod 1: START = 25 vs. CAREFLIGHT = 19). WNIOSKI: Efektywność wybranych systemów segregacji medycznej (START, SIEVE oraz CAREFLIGHT) jest istotnie zróżnicowana wśród pacjentów w kodzie żółtym i czerwonym. Uwzględniając najwyższy kod pilności, najbardziej czułą selekcję wykazuje system START, a najmniej czułą - CAREFLIGHT.

Laura McAtackneyArhuus UniversityDenmark The Many Forms and Meanings of (Peace) Walls in Contemporary Northern Ireland Abstract: Peace walls are a longstanding materialization of the conflict in Northern Ireland, known as the Troubles c.1968-c.1998. The walls have been one of the only security infrastructural forms associated with the violence to have continued and grown into the post-conflict context. They have often been a forgotten materialization of conflict due to their ‘temporary’ nature and their restriction to working-class, urban areas. While there are increasing moves to have these walls removed, or at least to put policies in place to allow them to be taken down in consultation with the communities beside them, there has been little consideration of the long-term impacts on public memory of material segregation. This article uses peace walls in Belfast as a case-study of the unforeseen repercussions of long-term segregation of divided communities. It offers a warning to the current generation of politicians regarding not only the role of what ideological walls are intended to do, but also the impacts they can have that were not intended.  Keywords: Belfast, segregation, peace walls, memorials, gender, victimhood

Opis:
Praca dotyczy przepływów i wymiany masy w układach dwufazowych ciecz - ciecz i ciecz - ciało stałe. W przypadku układów ciecz - ciało stałe badano proces przestrzennej segregacji cząstek ciała stałego, zaś dla układów ciecz - ciecz skoncentrowano się na problemie stabilności przepływu. Stabilność przepływu układu ciecz — ciecz badano wykorzystując rozwiązania analityczne i obliczenia CFD. Transport masy interpretowano stosując modele Lewicha, Batchelora i Polyanina.
This work considers the process of flow and mass transfer in the liquid - liquid and liquid - solid systems. In case of liquid - solid system the process of particles segregation was considered. In case of liquid - liquid system the aim of this work was to examine the appearance of flow instability. Stability analysis was conducted using analytical solutions and CFD calculations. Mass transfer was interpreted using models of Levich, Batchelor and Pofyanin.

Opis:
In general, uniform mixing of particles is desirable in the process of particle handling. However, during the charging of sinter feed and upper ore, size segregation must be induced to prevent heat imbalance, ensure bed permeability, and prevent the loss of fine ore. In this study, upper ore charging was simulated using a discrete element method (DEM) to find the optimal method for controlling particle size segregation, and the segregation characteristics in the upper ore bed were investigated when a deflector plate was applied to the charging machine. The degree of vertical segregation increased when a deflector plate was applied, and it was confirmed that the segregation direction in the upper ore bed can be controlled by adjusting the charging direction of the upper ore by using a deflector plate. In order to apply this method directly to the actual process, further study is needed to understand the influence of the characteristics of the deflector plate such as length and angle.

Opis:
Genetical analyses were conducted to find linkages and the locus of the gene calf on the Pisum chromosome map. The recessive, pleiotropic gene calf (enlarged and undulated leaflets, stipules, flowers and pods, plant sterile), artificially induced (the initial line-Large Podded G-20, the mutagene-DES and NMU) was described by Sharma in 1975. An identical mutant gene at the same locus was isolated in our research (the initial line - cv. Pegro, the mutagene - fast neutrons). Two lines were included in the Pisum gene bank - the type line for the gene calf - Wt 15873 and the representative line - Wt 16024. In linkage studies the representative line was crossed with tester lines bearing gene markers. Analyses of dihybrid segregation in F₂ generations revealed linkages of the gene calf with chromosome 2 markers. Two isozymic markers helped to reveal the calf locus on chromosome 2 with the following gene order: Orp - Calf - K - Pgm-p - Fum. This is in agreement with the current Pisum linkage map.

Opis:
The roots that raised Elvis Presley to become the man that he is in history, are not found in rock’n’roll but they go much deeper. They are found in the Gospel, in what Joe Moscheo defined as “the Gospel side of Elvis”. This paper highlights the gospel music of Elvis Presley and its vast impact on American society and religion. One of the aims of this article is to underline the impact that sacred music had over Presley’s artistical work and how Elvis and his Southern spirituality influenced the history of Christian music. One more important aspect of this paper argues the worldwide role Presley had as an evangelist of the Gospel, and how he influenced Christian identity and its values among Americans. This paper tried to answer to Mark Duffet’s question: “If star musicians are positioned as centers of attention, what happens when they use their privileged position in the spotlight to offer a ‘spiritual’ message?”. As a result, this paper offers original contents of Elvis Presley’s faith and spirituality and is intended as a starting point for future studies. Surprisingly, few researchers have evaluated the effect the singer had on evangelization and gospel music development. Previous studies have mostly paid attention to the role that Elvis played on the Rock’n’Roll scene and the iconic legend created around him. They forget that the Gospel is a key part of Presley’s life and music.

Opis:
Waste management is a challenging problem for most of the countries. The current waste segregation and the collection method are not efficient and cost-effective. In this paper, a prototype is presented for smart waste management. It is also capable of waste segregation at the ground level and providing real-time data to the administrator. Impact and cost analysis of the deployment of smartbin is also presented considering one ward of Ahmedabad Municipal Corporation. It is clear from that deployment of this smartbin will save about 40% of the current expenditure for that ward.

Opis:
Rosnąca ilość odpadów, ich selekcja i zbiór stały się globalnym problemem, którego rozwiązanie wymaga zarówno zaangażowania logistycznego, jak i prawnego. Ich transport jest elementem gospodarki odpadami. Transport odpadów to proces przenoszenia ładunku z miejsca jego wytworzenia do miejsca jego przechowywania, odzysku lub unieszkodliwienia. Usługi transportowe związane z obsługą odpadów są świadczone przez niezależne firmy transportowe lub przez firmy zajmujące się odzyskiem, magazynowaniem lub wykorzystaniem odpadów. Do tego celu wykorzystywane są specjalistyczne pojazdy.
The increasing volume of waste has become a global problem, solution of which requires logistic and legal engagement. Waste transport is the management of elements of the economy. It is also the process of relocation of cargo from the place of generation to the place of storage. Transportation services connected with handling of waste are rendered by independent transportation companies or by companies dealing with recovery, storage or utilization of waste.

Opis:
In this study, a fluidized bed separator incorporating inclined channels, the Reflux Classifier (RC), was modeled to describe the transport behavior of mono-sized solid particles using a 2D computational segregation-dispersion model. The model is a volume flux-based model comprising the dispersion and segregation fluxes. Simulations were performed to examine variations in the solid volume fraction of particle species of size 0.163 mm and density 2450 kg/m3 by altering variables such as fluidization velocity, underflow rate and water flux in the feed. The system achieved a maximum solid volume fraction of 0.50 (v/v) near the base at a fluidization velocity 0.00020 m/s, that reduced to 0.20 at the fluidization velocity 0.0060 m/s. Overall, the results showed a decrease in the average solid volume fraction from 0.37 to 0.21 for the corresponding fluidization velocities. Simulation results also successfully demonstrated the capacity of the RC in retaining the solid particles at a superficial fluidization velocity 0.020 m/s, significantly higher than the terminal settling velocity, 0.015 m/s, of the solid particles, due to the presence of an inclined channel. Similarly, with increasing the underflow rate, the average solid volume fraction decreased from 0.29 to 0.055 due to the discharge of a larger quantity of solid particles from the base. Furthermore, a higher concentration of solid particles was observed in the inclined section at lower water flux in the feed stream. Additionally, flux balance calculations were carried out at different points within the RC to ensure the accuracy of the model predictions.
