Data on cadmium distribution in the soils of industrial, residential and recreational areas of Dniprodzerzhinsk city are presented. According to the classification of urban soils the following types of soils were identified in the city: urban soil proper, plantosoil, anthropogenic-surface-transformed natural soil and lawn soil. We have made the estimation of cadmium content. The problem of soils contamination in the city with high anthropogenic load is discussed. The total cadmium content in the industrial, residential and recreational soils of Dniprodzerzhinsk varies within 0.6–10.5 mg/kg, but movable forms make 0.1–3.4 mg/kg of soil. Cadmium in the urban soil proper of the right-bank city surpasses the maximum permissible concentration (MPC) twice. At the same time the soils in the left-bank area and in the eastern and western areas of the right-bank were under MPC.

On the territory of the left-bank part of Perm, the urban pedocomplexes (UPC) were distinguished as a combination of soil and technogenic surface formations on the same soil-forming rocks within a certain functional zone. Within the UPC, formed on eluvial-deluvial loams and clays in the zone of multi-storey buildings, the surface horizons of soils and TSF (technogenic surface formations) were studied. A change in the zonal trend of humus formation in reclaimed soils was observed as an increase in the content of organic matter, as well as in a change in the type of humus to the humate side. The conservation of zonal features of humus formation in non-purposefully recultivated urban soils and TSF was noted. It manifests in a low or medium content of organic carbon, the formation of a humate-fulvate type of humus. Keywords: URBAN ECOLOGY, URBAN SOILS, URBAN PEDOCOMPLEX, HUMUS, HUMUS TYPE, SOIL PROPERTIES

The open-air Upper Paleolithic site of Sunghir (Сунгирь; Sungir’) is located along the northeastern edge of the Vladimir urban area, Russia, 192 km north of Moscow (56°10'30"N, 40°30'30"E). It is within the village of Dobrogo, currently absorbed into the city of Vladimir. The site is on the high left bank of the Klyazma River and on the right bank of the Sunghir stream close to where it flows into the river, ~750 m from the former, ~600 m from the latter, and ~50 m above the current level of the Klyazma. At the time of its discovery in 1955, the site was buried under several meters of loess, which were being removed with heavy equipment by the Vladimir Ceramic (or Brick) Works. The archeological material (see Bader 1978) was first unearthed in June 1955 by A.F. Nacharov, operating a power-shovel to remove sediment from the clay pit of the Vladimir Ceramic Works. During the summer, bones and eventually artifacts and hearths were turning up in the bucket of the equipment in a layer 15 to 20 cm thick and 2.8 to 3.2 m below the surface. Nacharov turned the artifacts and some of the bones over to the Vladimir District Regional Museum; the site was then repeatedly inspected by local individuals and V.M. Maslov, with word of the site eventually reaching O.N. Bader. The site was further investigated during the summer of 1956, with the first assessments of the nature and extent of the Paleolithic remains. As a result of the richness of the material, and especially the location of the site—it was the furthest north Paleolithic site known at the time—it was visited by series of specialists and in 1957 systematic long-term excavations were begun under the direction of O.N. Bader (archeology), V.I. Gromov (geology, fauna), and V.N. Sukachev (flora). Systematic excavations then proceeded for sixteen seasons from 1957 to 1977; more limited work has been undertaken recently (Seleznev 2008).

The objective of this research is the clarification of ecological peculiarities of cadmium dispersal at the urbanized terrain edaphotopes of Dniprodzerzhinsk. Heavy metals have been widely discussed in a huge number of researches. Special attention should be paid to cadmium as one of the most hazardous environmental toxic agents. There exist multiple data on cadmium content in various soil types of Ukraine, but until the present time there’s no full information as for the accurate geochemical behavior of cadmium in the soils, as well as for the priority impact of one or another soil property upon its concentration in certain soil types – natural ones or anthropogenically modified ones. The applicability of such researches is first of all determined by the necessity to decrease the hazardous environmental consequences of soil contamination with cadmium, as well as to improve the living conditions of the population. Evaluation of the technology-related impact upon the city soil layer is of current concern in terms of monitoring that is corresponding to the modern tasks for the environmental condition control. The article highlights the issue of ecological peculiarities of cadmium dispersal at the urbanized terrain edaphotopes of Dniprodzerzhinsk: variety of cadmium concentration being formed under the natural and anthropogenous influence in the soils of Dniprodzerzhinsk makes difficult to solve the problem of soil contamination with such chemical element. Soils with various content of cadmium can be found within the limits of the city, underneath the steppe vegetation. Content differentiation is attributed to rather diverse set of processes in the soil and to various properties of the soils. Edaphotopes of all studied right-bank urbanized terrains are cadmium contaminated to any extent. Cadmium content in the soil layer of the administrative districts of Dniprodzerzhinsk is ascending as follows: Dniprovsky district (0.6–9.9 mg/kg) – Bagliy district (1.0–10.5 mg/kg) – Zavodsky district (1.5–10.8 mg/kg). Evaluation of intensity of the technology-related geochemical abnormalities in the city soils has been provided by the abnormality level factor. The lowest (weak) soil contamination level can be observed within the edaphotopes of the left-bank area of Dniprovsky district of the city. High and very high soil contamination levels can be observed within the urbanized terrains of the right-bank part of the city at Bagliy and Zavodsky districts (eastern, central and western areas). Results of the statistical processing of the experimental material show the ratios of correlation of cadmium content and mechanical composition of the soil and humus. Absence of cadmium correlation with physical clay-fraction of soil, as well as close significant relation with humus enable us to associate its presence in the soils with biogenous accumulation, being also the evidence of the anthropogenous impact upon cadmium content in the soil layer.

The Old Belgrade Fairground complex is the large area in the center of Belgrade that is completely isolated from other parts of Belgrade: it is one of the most devastated city areas, populated by poor inhabitants, often by those from the marginal groups, burdened with tragic history and it represents one of hardest problems for planners to solve. It is situated on the left bank of the Sava River between two bridges and downtown New Belgrade. Opposite to it, the Sava Amphitheatre slopes down the Belgrade Ridge towards the river. The complex was built in the thirties of the 20th century across the River Sava in the area that was an unpopulated swamp - Belgrade was situated on the right Sava bank. It was meant to be modern extension of oriental city, which could represent the western tendencies of the young state (Kingdom of Yugoslavia) and its capital. Modern and monumental complex of exhibition and commercial pavilions was built, and started its life with national and international fairs and exhibitions. World War 2 changed its destiny: German occupation forces transformed the complex into the concentration camp, where thousands of people were tortured and killed. After the war, new republican government, both communist and antifascist, had double frustration regarding this space: it?s tragic (during the War) and "capitalist" (before the War) past, so complex that was absolutely ignored in the period of the postwar renewal, and the result is described at the beginning of this text. This paper discusses the possibility to conciliate historical roles of the complex, and to realize it?s potentials in the modern world. Facts of the complex?s history are presented in the first part of the paper. Further on, these facts are analyzed in the context of contemporary city development of Belgrade in particular but globally, too.. Finally, some guidelines for crossing the gap between this area and the rest of the city are presented in the third part of the paper.

Amasya, wrote a visitor at the turn of this century, is “the most picturesque town of all Anatolia, the Baghdad of Rûm”. Another called the city “l'Oxford de l'Anatolie”. One of its principal charms is the River Iris, the Yeşil Irmak, which runs through the town. Beautiful but not potable: “Tokat dumps in it, Amasya drinks it” is a Turkish proverb at least as old as Evliye Çelebi, who visited the town in the first half of the seventeenth century.In ancient times the city would seem to have taken its water from a source in the neighbouring hills. It was carried along an aqueduct cut, for the most part, into the face of the cliffs which form the side of the river valley south and west of the town and on the right bank of the river (Fig. 1). The castle of Amasya, on the left bank, had its own arrangements for water supply described by the geographer Strabo, a native of the city, and these should not be confused with the aqueduct on the right bank.

The architecture of the city of Paris encompasses a history of more than two millennia. Paris’s earliest known architecture dates to the start of the 1st century, when the Gallo-Roman city of Lutetia developed on the Left Bank and the Île de la Cité. The city subsequently expanded across the Right Bank and the present location of many important ecclesiastical monuments was determined after Clovis I, king of the Franks, made Paris the seat of the Merovingian Kingdom at the start of the 6th century. The cathedral of Notre-Dame, the abbey church of Saint-Germain-des-Près, and the French Panthéon (formerly the church of Sainte-Geneviève) were all built on Merovingian sites. Although there is little evidence of the city’s architecture from these early periods, it nevertheless established two enduring principles that broadly characterize the development of the city’s architecture over time. First, Paris’s urban fabric has followed an ongoing process of centrifugal expansion, engulfing the surrounding land until 1869 when it was decided to annex the old eleven faubourgs and make them the surrounding arrondissements, whose outer edges mark the municipal limits of the city. In the 20th and 21st centuries, urban development projects continue apace in the banlieues, or suburbs, beyond the city’s limits, while building campaigns within the capital have principally taken the form of urban infill and renovation projects. Second, subsequent rulers have consistently appropriated the same sites and rebuilt or extended them as a mark of political ambition. This was the case for important Christian sites as well as for the city’s palace complexes, such as the early-13th-century Louvre, which was consistently occupied, rebuilt, and expanded during the Old Regime; partially used as a museum during the French Revolution; and only transformed into a museum in its entirety in the 1980s when President François Mitterand stamped the buildings with his own political ambition in his bid to again transform the city. Collectively, the process of urban expansion and the reappropriation of sites have made the city’s architecture dense with historical layers from different periods of time. It has been the task of historians to peel back these layers to study the social, cultural, and material significance of the city’s architecture. To present the literature on Paris’s architecture in light of its vast history, the following bibliography begins with more general literature and research sources, and it then progresses chronologically, starting with Lutetia’s architecture and ending at the close of the 20th century. As the bibliography moves forward in time, the scholarship becomes denser, especially in the 19th century. This focus in large part reflects the recent nature of the city’s existing built fabric, which was mostly constructed starting in the mid-19th century.

Abstract Arch bridges are slender structures and can be efficiently used in the range of medium to large spans. These structures have an improved aesthetic aspect and in the same time a low construction height, with obvious advantages regarding reduced costs in the infrastructuers and their foundations. For this type of structures usually composite or orthotropic decks are used. Lately, innovative solutions have been used in designing arch bridges, especially discarding the top wind bracing system. The level of axial forces and bending moments in the arches and tie imply the design of sections with sufficient stiffness and strength in both directions in order to ensure the general stability of the arches, without the need for top wind bracing. Moreover, the cross section of the arches is not constant, but shifts in accordance with the variation of the bending moments, in order to ensure their lateral stability. This paper studies a road bridge with parallel Bowstring arches, with a span of 108m and a carriageway 7.00m wide, sustained by a deck made up of crossbeams 2m apart and a concrete slab. The main beams are held by ties arranged in the Langer system, 10 to 14m apart from each other. The sag of the arches is 18m high. The analyzed structure was proposed for construction in the city of Oradea and is used for crossing the “Crişul Repede” river, between Oneştilor street on the left bank and the Sovata, Fagului and Carpaţi streets on the right bank. The performed analyses have the following two main objectives: to establish the critical load for which the failure of the arches occurs by instability and to underline the influence of different wind bracing systems on the bridge’s collapse loads respectively.

In market conditions, to ensure the economic development of enterprises are forced to constantly monitor and increase the economic efficiency of their activities. The strategy of the enterprises of the electric power industry should provide for the creation of a comprehensive system of measures aimed at achieving promising efficiency parameters. The level of profitability is most affected by the size of production costs, which indicates significant amount production costs, but the technical potential of CHP is not exhausted, which allows to increase the load on existing equipment of enterprise. In addition, the market position is not clearly assigned to the enterprise, which allows for the development of a new market niche in the form of the left bank of the city. The results of the restoration of the heating system on the right and left banks will allow the enterprise to become an integral part of the city's infrastructure.

The paper describes the development of the 1998 revision of the Psychological Society of Ireland's Code of Professional Ethics. The Code incorporates the European Meta-Code of Ethics and an ethical decision-making procedure borrowed from the Canadian Psychological Association. An example using the procedure is presented. To aid decision making, a classification of different kinds of stakeholder (i.e., interested party) affected by ethical decisions is offered. The author contends (1) that psychologists should assert the right, which is an important aspect of professional autonomy, to make discretionary judgments, (2) that to be justified in doing so they need to educate themselves in sound and deliberative judgment, and (3) that the process is facilitated by a code such as the Irish one, which emphasizes ethical awareness and decision making. The need for awareness and judgment is underlined by the variability in the ethical codes of different organizations and different European states: in such a context, codes should be used as broad yardsticks, rather than precise templates.
