Coal exploitation has produced a huge amount of mining waste whose considerable part is being piled on the waste dumps. The analysis was carried out in the area of Ruda Slaska city. The waste dumps are located within the city limits. The spontaneous processes of succession can thus help to manage such urban landscapes in compliance with the principles of sustainable development. The majority of such territories are managed and restored. However, some areas avoid reclamation processes and instead undergo the process of spontaneous vegetation or even landscape succession. The aim of the research is first and foremost to characterize the spontaneous succession of vegetation in terms of habitat requirements to which we include light, temperature, humidity, trophic conditions, reaction (pH), granulometric composition and plant life forms. In the second place the aim was to determine the direction of the spontaneous succession of vegetation as well as to demonstrate the usefulness of such types of research while planning the reclamation of the post-mining areas that have been deformed to suit the urban landscape. The result of the analysis showed the occurrence of 108 vascular plants in I and 60 in II waste dump. It was mostly photophilous species that prevailed on both waste dumps. They were mostly native as well as non-native species. Some species like Calamagrosits epigejos, Robinia pseudoacacia, Betula pendula have high biological productivity despite unfavorable conditions. The overgrown dumps shaped the image of the city landscape in a specific way. However, the investigation showed that the number of species on the waste dumps increases with time. The results of the research into the conditions that reign on the dumping grounds provide the basis for projects of reclaiming the post-mining sites, in particular the waste dumps, from raw material extraction, as well as demonstrate the usefulness of the spontaneous succession of plants.

The purpose of this study is to present the distribution and characteristics of xerothermic flora located within Lublin (51<sup>o</sup>08’-51<sup>o</sup>18’N and 22<sup>o</sup>27’-22<sup>o</sup>41E). The data on this flora have been derived from the literature and herbarium collections as well as they were collected during field research conducted in 2002-2009. Family affiliation, life forms, geographical-historical groups, the degree of synanthropization of species and habitat, categories of threat are discussed in this paper. 107 xerothermic species belonging to 26 families and 70 genera were reported from the area of Lublin. The number constitutes 10% of the city’s flora. The most numerous are plants from the classes <i>Festuco-Brometea</i> (70 species), <i>Trifolio-Geranietea</i> sanguinei (21) and <i>Rhamno-Prunetea</i> (16). All extinct species (8) belong to the class <i>Festuco-Brometea</i>. The analysis of the spectrum of life forms indicates that the biggest share in the flora of Lublin was observed in the group of hemicryptophytes (57 species) and phanerophytes (14). The native species (103) dominate over the group of alien ones (4 species). The group of xerothermic plants comprises 21 legally protected and endangered species. Xerothermic plants exhibit a mosaic distribution in the area of Lublin. The frequency (measured as the presence of a species in a study unit, one ATPOL square) ranged from 1 to 44 species. Two main features of the analyzed area seemed to be responsible for species distribution: the value of the Real Hemeroby Index (RIH) and the history of the flora.

"The City of Oslo in Jan Erik Vold’s Poems. The aim of this paper is to examine, from a cultural and social perspective, the Norwegian urban areas and everyday situations in Jan Erik Vold’s (b. 1939) poems. Our close-reading technique reveals important social aspects, different places and streets, located in the capital city of Norway, Oslo. These urban poems written by the contemporary Norwegian poet Jan Erik Vold contribute to the reconstruction of a new Norwegian cultural identity as it is reflected in a selection of poems taken from Mor Godhjertas glade versjon. Ja (Mother Goodhearted’s Happy Version. Yes, 1968), followed by the poet’s wanderings in the city of Oslo in En som het Abel Ek (One Named Abel Ek, 1988), and concluding with his bitter social criticism in Elg (Moose, 1989) and IKKE. Skillingstrykk fra nittitallet (Not: Broadsides from the Nineties, 1993). Vold’s urban poems emphasise the transition from nyenkle (new simple), friendly and descriptive poems which present closely the city of Oslo on foot, to short, political and social critical poems from the 90s. Thus, it is of great importance to traverse various urban ‘landscapes’ in different periods of time, beginning with the 1960s, followed by the 80s and the 90s.

Abstract The aim of this study was to determine the ecological characteristics of vascular plants colonizing serpentine mining waste dumps and quarries in Lower Silesia. The investigated flora was analyzed with regard to species composition, geographical-historical status, life forms, as well as selected ecological factors, such as light and trophic preferences, soil moisture and reaction, value of resistance to increased heavy metals content in the soil, seed dispersal modes and occurrence of mycorrhiza. There were 113 species of vascular plants, belonging to 28 families, found on seven sites in the study. The most numerous families were Asteraceae, Poaceae, Fabaceae and Caryophyllaceae. Only 13% of all plants recorded occurred on at least five of the study sites. The most numerous were species related to dry grassland communities, particularly of the Festuco-Brometea class, which included taxa endangered in the region of Lower Silesia: Avenula pratensis, Salvia pratensis, Festuca valesiaca. Apophytes dominated in the flora of the investigated communities. Hemicryptophytes were the most numerous group and therophytes were also abundant. The serpentine mining waste dumps and querries hosted heliophilous species which prefer mesic or dry habitats moderately poor in nutrients, featuring neutral soil reaction. On two study sites 30% of the flora composition consisted of species that tolerate an increased content of heavy metals in the soil. Anemochoric species were the most numerous with regard to types of seed dispersal. Species with an arbuscular type of mycorrhiza were definitely dominant in the flora of all the study sites, however, the number of nonmycorrhizal species was also relatively high. It was suggested that both the specific characteristics of the habitats from serpentine mining and the vegetation of adjacent areas had a major impact on the flora composition of the communities in the investigated sites.

This paper investigates the main parameters influencing the plastic behavior of clays used for traditional ceramics production. For this, twenty-six clayey pastes were selected from twelve traditional ceramic plants around the city of Marrakech (Morocco). According to the lithology, six different types of materials are used as raw material in the ceramic industry of this region. Emphasis is placed on the impact of the characteristics of these clayey materials upon the plastic behavior of these clays. The pastes were characterized through their consistency using the Atterberg limits. It has been concluded that the gain size, the mineralogical and the clay mineral composition and content, the effect of diagenesis and the presence of talc-pyrophyllite association play the most important role in the control of the plasticity behavior.

&lt;p&gt;The city of &amp;#201;vora, a World Heritage Site recognized by UNESCO in 1986, also owes this recognition to the stones that built its monuments and preserve them until today.&lt;/p&gt;&lt;p&gt;This work brings together the contributions that we have gathered over the past three decades and allow us to have a very complete idea, not only about the materials used in the hundreds of monuments and historic buildings but also about their provenance. If some materials are so emblematic that they allow an immediate identification with the naked eye, others needed more sophisticated and precise techniques so that there was no doubt about their origin.&lt;/p&gt;&lt;p&gt;The igneous rocks and gneisses of granite composition are part of the &amp;#8220;Massif of &amp;#201;vora&amp;#8221; on which the city is built. Thus, and quite naturally they are by far the most represented group in monuments from all historical periods. Its function is essentially structural, but there are also functional, ornamental and decorative objects. For example, the oldest megalithic structures found in the vicinity of the city are made up of large granite blocks that often had to be transported to their locations.&lt;/p&gt;&lt;p&gt;On the other hand, many gargoyles and statues that decorate the churches are also made up of these granite rocks. On these, the natural erosion of centuries of exposure to the environment has led to a state of alteration, sometimes very accentuated, which would justify its replacement by replicas sculpted in similar rocks. Provenance studies have made it possible to identify old quarries in the vicinity of the city where, on the one hand, the ancient rock extraction techniques can be observed and on the other hand, they allow the obtaining of the raw material necessary for these restoration and conservation works. In any case, they are places that need to be inventoried and protected, with the municipality already aware of their existence.&lt;/p&gt;&lt;p&gt;As well as the monuments of the Roman Period, also the structures of the Medieval Period, such as the city walls, the Cathedral (started to be built in 1186 AD) and all the great churches, were also built with these granitoids.&lt;/p&gt;&lt;p&gt;In addition to these rocks, many others of multiple varieties and origins are present. The marbles, especially the Estremoz Marbles (Global Heritage Stone Resource), are ubiquitous in the city, but there are also emblematic marbles from other places, some easily identifiable (ie Viana do Alentejo, Escoural, Trigaches, Serpa and Vila Verde de Ficalho, for presenting mineralogy, textures, colors and patterns which, together with more recent analytical techniques, have confirmed its provenance.&lt;/p&gt;&lt;p&gt;Sedimentary rocks, with emphasis on Portuguese Mesozoic limestones, ie Lioz - GHSR and Brecha da Arr&amp;#225;bida - GHSR candidate, among others more rare and with very specific use in ornamental details, are also present and contribute to enrich a heritage in stone that makes this city so special and very popular with tourists of all nationalities.&lt;/p&gt;&lt;p&gt;Acknowledgments: the authors thank to FCT for funding the ICT (UID/GEO/04683/2019), as well as COMPETE POCI-01-0145-FEDER-007690.&lt;/p&gt;

The urban landscape assesment as an important element in the quality of life and the sustainable development of the city constitutes an incipient field of investigation from a new perspective that adds meanings and values. An analysis of the different methodological developments and national and international experiences in the assessment of these landscapes will highlight its importance as a strategic element to improve the quality of the city. It starts from the concept of assessment as a system where tangible and intangible values ​​are considered by the population and the experts. These include among other formal, economic, environmental, social, cultural issues (…) and the relationships between them. Consideration of the opinions of experts from different points of view such as urbanism and architecture but also environment, economy, geography, history, archeology, sociology, social assistance, etc. Together with the preferences expressed by the population regarding the spaces they inhabit on a daily basis and their aspirations, strengthen the sense of belonging and the identity of the place as key elements in the perception of the urban landscapes that allows to contribute new qualities, integration criteria and ​​contemporary values to any type of intervention. These are strategies and intervention procedures that start from the complexity of the city as a system and incorporate the perception that citizens have or will have of their immediate environment.  References: Czynska Klara and Pawel Rubinowicz (2015). ´Visual protection Surface method: Cityscape values in context of tall buildings´.

As frações granulométricas do solo são consideradas recursos naturais não renováveis, devido a escala de tempo necessária para sua formação. A argila possui elevada disponibilidade na natureza, e por isso seu uso ainda é indiscriminado. É a matéria-prima principal para as indústrias de cerâmica vermelha pulverizadas em todo o território brasileiro. O objetivo do trabalho foi realizar uma discussão acerca do recurso natural não renovável argila e seu uso no processo produtivo da Indústria de cerâmica vermelha. Este foi desenvolvido através de pesquisa bibliográfica, e estudo de caso com realização de visitas técnicas a uma indústria de cerâmica vermelha localizada no município de Paudalho no estado de Pernambuco. No ano de 2013 a Indústria X adquiriu para estoque e consumo 70.161 toneladas, para uma produção de 35.806.268 blocos de cerâmica. De todo o quantitativo produzido houve uma perda de 7,5%, que reflete em 4.768 toneladas de argila e num prejuízo aproximado de R$ 845.835,52. Através do trabalho realizado percebe-se que há uma necessidade de planejamento da exploração e uso dos recursos naturais não renováveis, pois estes podem se tornar escassos e inviabilizar determinados processos produtivos. Isso pode acarretar em conflitos sociais e econômicos, pela valoração dos recursos e diminuição de disponibilidade para uso, ocasionando redução dos lucros por parte dos empresários e por consequência diminuição na oferta de empregos.Use of clay in the production process of the Red Ceramics: A case study in the city of Paudalho, Pernambuco Abstract: The fractions of soil are considered non-renewable natural resources, because the time scale required for its formation. Clay has high availability in nature, and therefore its use is still indiscriminate. It is the main raw material for the manufacture of red ceramic sprayed throughout the Brazilian territory. The objective was to conduct a discussion of non-renewable natural resource clay and its use in industry's production process of red ceramic. It was developed through literature review and case study of technical a red ceramic industry in the municipality of Paudalho in Pernambuco state visits. In 2013 the X Industry acquired for stock and consumption 70,161 tons, for a production of 35,806,268 ceramic blocks. The entire quantity produced there was a loss of 7.5%, which reflects in 4,768 tons of clay and an approximate loss of R $ 845,835.52. Through work is noticed that there is a need for planning of exploration and use of non-renewable natural resources, as they may become scarce and derail certain production processes. This can lead to social and economic conflicts, the valuation of resources and reduced availability for use, resulting in lower profits for entrepreneurs and consequently decrease in the supply of jobs.

<p>El propósito de este artículo es reflexionar críticamente en torno a la noción de paisaje y sus vinculaciones con modos -diferenciados y desiguales- de imaginar y habitar la ciudad. El análisis se sustenta en un estudio de caso en La Boca, un barrio de la zona sur de la Ciudad de Buenos Aires, donde confluyen procesos de reconversión urbana y déficit habitacional. Desde un abordaje etnográfico junto al uso de fuentes secundarias, el trabajo explora las principales características y transformaciones socioespaciales del barrio en relación con el resto de la ciudad. El artículo focaliza en prácticas de habitantes y usuarios, en diálogo con distintas aproximaciones al concepto de paisaje, y con estudios que destacan la relación entre una estetización de las ciudades contemporáneas y un modelo exclusivo de ciudad. Desde una perspectiva del habitar -centrada en las prácticas urbanas- el enfoque propuesto procura tomar en cuenta las tensiones e imbricaciones entre los paisajes urbanos cotidianos de sus habitantes y los paisajes culturales orientados a un consumo visual, incorporando en el análisis las relaciones desiguales de poder.</p><p><br /><strong>Abstract</strong></p><p><br />This article aims to critically reflect upon the notion of landscape and its links with -differentiated and unequal- ways of imagining and inhabiting the city. The analysis is based on a case study in La Boca, a neighborhood in the southern area of the city of Buenos Aires, where urban reconversion processes coexists with housing insufficiency. Through an ethnographic approach supplemented with secondary sources, the paper explores the main characteristics and socio-spatial transformations of the neighborhood in relation with the rest of the city. The article focuses in dwellers and passersby practices, in dialogue with different approaches to the concept of landscape, and with studies that emphasize the relation between the aestheticisation of the contemporary cities and an exclusive city model. From a dwelling perspective -centered in urban practices- the proposed approach seeks take into account the tensions and interweaving between the daily urban landscapes of La Boca’ s dwellers and the cultural landscapes oriented toward visual consumption, incorporating in the analysis the unequal power relations.</p>
