Industrial sites are brownfields left in the process of urban development, which were originally considered as the burden of the city. However, in today’s lack of land resources, industrial sites have become valuable assets of the city. Further excavation and effective use of them is one of the important ways to alleviate the tension of urban land use. The strategy of ecological reconstruction and sustainable design in the landscape of industrial sites is mainly reflected in the minimal intervention in the natural ecology of the site, the use of renewable materials and resources, the retention of native plants, human history and site memory. It makes the ecology of urban industrial site landscape more balanced, enhances the uniqueness and experience of urban industrial site landscape, meets the spiritual and physiological needs of people in the city, and realizes the sharing of industrial site landscape to the public’s natural ecology, land, industrial spirit, history and humanity.

A cosmetologia é a ciência que engloba e estuda os cosméticos, desde conceitos iniciais até a sua fabricação, tornando-se uma ciência multidisciplinar. Para garantia de um uso seguro e eficaz dos cosméticos é necessário a realização de análises para se conseguir um padrão de qualidade. Quando há indícios de contaminação por microrganismos no cosmético, diversos problemas podem ser encontrados, como a ocorrência de patologias específicas, causando altos riscos e complicações à saúde do usuário. O objetivo deste trabalho foi investigar qualitativamente através de análises microbiológicas a qualidade dos produtos cosméticos de maquiagem usados de forma compartilhada, utilizando amostras colhidas aleatoriamente em uma loja de varejo, que foi selecionada por ser de grande circulação, da cidade de Juazeiro do Norte, Ceará. Nesta pesquisa foram analisadas oito amostras coletadas durante o período de outubro e novembro de 2017. As análises que foram realizadas seguiram a Farmacopeia brasileira. Como resultado obteve-se um percentual de 87,5 % de contaminação microbiana, evidenciando a presença de Staphylococcus aureus, Escherichia coli, Enterococcus sp. e Pseudomonas aeruginosa, sendo que apenas uma das oito amostras analisadas mostrou-se adequada para uso seguindo os limites de aceitação microbiológicas permitidos por lei. Baseados nesses resultados foi possível concluir que o índice de contaminação das amostras de batons que são utilizadas de modo compartilhado são potencialmente maiores. Com isso, intensifica-se a necessidade de medidas que impeçam o compartilhamento dos produtos cosméticos, com a finalidade de diminuir o risco de uma infecção coletiva.   Palavras-chave: Cosméticos. Uso compartilhado. Contaminação.   Abstract Cosmetology is the science that encompasses and studies cosmetics, from initial concepts to their manufacture, becoming a multidisciplinary science. To guarantee a safe and effective use of cosmetics it is necessary to carry out analyzes to achieve a quality standard. When there is evidence of contamination by microorganisms in the cosmetic, several problems can be found, such as the occurrence of specific pathologies, causing high risks and complications to the health of the user. The objective of this scientific work was to qualitatively investigate through microbiological analysis the quality of cosmetic makeup products used in a shared way, using samples collected randomly in a retail store, which was selected because it is of great circulation, in the city of Juazeiro do Norte, Ceará. In this research, eight (8) samples collected during the period of October and November 2017 were analyzed. The analyzes that were carried out followed the Brazilian Pharmacopoeia. As a result, a percentage of 87.5 % of microbial contamination was obtained, showing the presence of Staphylococcus aureus, Escherichia coli, Enterococcus sp. and Pseudomonas aeruginosa, with only one of the eight samples analyzed being suitable for use following the limits of microbiological acceptance allowed by law. Based on these results it was possible to conclude that the contamination index of the lipstick samples that are used in a shared way are potentially higher. As a result, the need for measures to prevent the sharing of cosmetic products is intensified, in order to reduce the risk of a collective infection.   Keywords: Cosmetics. Shared Use.

In order to control the chemical composition of atmospheric air in cities located in the zone of influence of petrochemical enterprises, automatic atmospheric air monitoring stations (ASKAV) are installed. For the effective use of experimental data, the authors of the article developed a data collection system with ASKAV, in which the air control in residential quarters and the gas mixture at the source of organized emissions are synchronized. The analysis of data on the concentration of pollutants in the atmospheric air of the Sterlitamak obtained from ASKAV, on the basis of which a list of marker substances for enterprises of the city was compiled. Priority sources of air pollution with marker substances during a different wind regime were identified. The authors developed models for changing the concentration of marker substances in the air using the method of factor regression. Based on the results of the cross-correlation function, the time of movement of the contaminated gas cloud from the source of emission to the residential area of the city is obtained. Conclusions are made about the effectiveness of the developed air monitoring system and the field of application of the acquired models.

Underlying Processes

In the context of the European city, the regeneration of former industrial sites is a unique opportunity to actively steer urban development. These plots of land gain strategic importance in actively triggering development on the city scale. Ideally, these interventions radiate beyond the individual site and contribute to the strengthening of the location as a whole. International competition between locations is rising and prosperous development a precondition for wealth and wellbeing. This approach to the regeneration of inner city plots makes high demands on all those involved. Our framework suggests a stronger focus of the conceptualization and analysis of idiosyncratic resources, to enable innovative approaches in planning. On the one hand, we are discussing spatially restrained urban plots, which have the capacity and need to be reset. On the other hand, each plot is a knot in the web of relations on a multiplicity of scales. The material city is nested into a set of interrelated scale levels – the plot, the quarter, the city, the region, potentially even the polycentric megacity region. The immaterial relations however span a multicity of scale levels. The challenge is to combine these two perspectives for their mutual benefit. The underlying processes are constitutive to urban space diversity, as urban form shapes urban life and vice versa.

O processo de construção e aprovação do novo conjunto de leis relativas ao zoneamento de uso e ocupação do solo em Curitiba oferece elementos para uma análise dos conflitos de interesses que regem a constituição de um arcabouço legal e da luta simbólica que traduz na elaboração de um discurso que não se realiza nos termos da lei, mas que se cristaliza no imaginário dos citadinos. Tentando analisar esse processo e identificar dispositivos passíveis de serem generalizados como eficazes no controle de ocupação e uso do solo de outras cidades-modelo, na busca do protagonismo nos movimentos de inserção na reestruturação econômica internacional, este texto examina e sumariza observações quanto: ao apoio da lei no reforço à modelização urbana de Curitiba; à ausência de mecanismos e instrumentos que contemplem suas relações com o espaço metropolitano; aos efeitos socioambientais decorrentes da aplicação da lei; às questões referentes à constitucionalidade e à observação de princípios democráticos; às disposições referentes à ampliação da atratividade ao capital internacional; a sua abertura à participação da sociedade civil e à legitimidade de seus resultados. Urban land use regulation: discussion about the Curitiba’s case Abstract In 1999, a new land use law was approved in Curitiba. Its construction and approval process offers elements to discuss the meaning of a legal frame in the reinforcement of a hegemonic power around a metropolitan space, and the creation of conditions to attract the international capital, mainly from the real estate market. Trying to analyse this process, identifying elements possible to be generalised in the land use regulation of protagonists’ cities, this study examines and summarises observations on the topics: law for highlight the city-model; the lack of metropolitan instruments; conflicts between Instruments and particular interests; urban and social effects; constitutionality and observation of democratic principles. Finalising, the study intends to discuss that the dispositions included in the law and its illegitimate participation procedures have resulted in a refusing among society segments.

China’s urban land use has shifted from incremental expansion to inventory eradication. The traditional extensive management mode is difficult to maintain, and the fundamental solution is to improve land use efficiency. Xi’an, the largest central city in Western China, was selected as the research area. The super-efficiency data envelopment analysis (DEA) model and Malmquist index method were used to measure the land use efficiency of each district and county in the city from the micro perspective, and the spatial-temporal change characteristics and main influencing factors of land use efficiency were analyzed, which not only made up for the research content of urban land use efficiency in China’s underdeveloped areas, but also pointed out the emphasis and direction for the improvement of urban land use efficiency. The results showed that: (1) The land use efficiency of Xi’an reflected the land use intensive level of the underdeveloped areas in Western China, that is, the overall intensive level was not high, the gap between the urban internal land use efficiency was large, the land use efficiency of the old urban area and the mature built-up area was relatively high, and the land use efficiency of the emerging expansion area and the edge area was relatively low. (2) Like the eastern economically developed areas, the land use efficiency of western economically underdeveloped areas was generally on the rise, while Xi’an showed the U-shaped upward evolution characteristics, and there were four types of changes in the city, that is, highly intensive, medium intensive, high–medium–low-intensive, and intensive–extensive. (3) Various cities should configure resources and optimize mechanism to improve their land use efficiency based on economic and social development. During the study period, Xi’an showed the law of evolution from the south edge area and the emerging expansion area to the main urban area. (4) The improvement of technological progress was the main contribution factor of the land use efficiency in underdeveloped areas of China, and the low-scale efficiency was the main influence factor that caused low land use efficiency. In future urban land use, efforts should be made to optimize and upgrade technology and strictly control the extensive use of land.

The expansion of urban areas and the increase in the number of buildings and urbanization characteristics, such as roads, affect the meteorological environment in urban areas, resulting in weakened pollutant dispersion. First, this paper uses GIS (geographic information system) spatial analysis technology and landscape ecology analysis methods to analyze the dynamic changes in land cover and landscape patterns in Chengdu as a result of urban development. Second, the most appropriate WRF (Weather Research and Forecasting) model parameterization scheme is selected and screened. Land-use data from different development stages in the city are included in the model, and the wind speed and temperature results simulated using new and old land-use data (1980 and 2015) are evaluated and compared. Finally, the results of the numerical simulations by the WRF-Chem air quality model using new and old land-use data are coupled with 0.25° × 0.25°-resolution MEIC (Multi-resolution Emission Inventory for China) emission source data from Tsinghua University. The results of the sensitivity experiments using the WRF-Chem model for the city under different development conditions and during different periods are discussed. The meteorological conditions and pollution sources remained unchanged as the land-use data changed, which revealed the impact of urban land-use changes on the simulation results of PM2.5 atmospheric pollutants. The results show the following. (1) From 1980 to 2015, the land-use changes in Chengdu were obvious, and cultivated land exhibited the greatest changes, followed by forestland. Under the influence of urban land-use dynamics and human activities, both the richness and evenness of the landscape in Chengdu increased. (2) The microphysical scheme WSM3 (WRF Single–Moment 3 class) and land-surface scheme SLAB (5-layer diffusion scheme) were the most suitable for simulating temperatures and wind speeds in the WRF model. The wind speed and temperature simulation results using the 2015 land-use data were better than those using the 1980 land-use data when assessed according to the coincidence index and correlation coefficient. (3) The WRF-Chem simulation results obtained for PM2.5 using the 2015 land-use data were better than those obtained using the 1980 land-use data in terms of the correlation coefficient and standard deviation. The concentration of PM2.5 in urban areas was higher than that in the suburbs, and the concentration of PM2.5 was lower on Longquan Mountain in Chengdu than in the surrounding areas.

Abstract. In this study, in the city of Karaj five classes of land use-cover including residential, agriculture, rangeland, forest and barren areas were considered and randomly in each class a total of 20 points were selected and vegetation and soil samples were taken. In plant samples, the amount of carbon sequestration was determined by calculating the amount of organic carbon by dry weight and in soil samples, the amount of carbon sequestration was determined by using Walleky and Black method, too. For each area, the average value of carbon sequestration of samples was introduced as carbon sequestration index of that class. Average values for each category were determined as an indicator of carbon sequestration of that class and then by using the DINAMICA EGO software a simulation was conducted using cellular automata approach to simulate changes in the classes of land use-cover in the city of Karaj. Finally, by using carbon sequestration index and the results of the simulation, changes in carbon sequestration in each class were calculated. On this basis, it was found that in the 15-year period from 2014 to 2029, not considering the residential class as the effective use of carbon sequestration, the greatest amount of carbon sequestration was found in the agricultural class and the lowest carbon sequestration was found in barren area. Also, agriculture class will be faced with the huge reduction of carbon sequestration, because of expansion of the residential area.

AbstractFinescale simulations (with 500-m grid spacing) using the Weather Research and Forecasting Model (WRF) were used to investigate impacts of urban processes and urbanization on a localized, summer, heavy rainfall in Beijing. Evaluation using radar and gauge data shows that this configuration of WRF with three-dimensional variational data assimilation of local weather and GPS precipitable water data can simulate this event generally well. Additional WRF simulations were conducted to test the sensitivity of simulation of this storm to different urban processes and urban land-use scenarios. The results confirm that the city does play an important role in determining storm movement and rainfall amount. Comparison of cases with and without the presence of the city of Beijing with respect to the approaching storm shows that the urban effect seems to lead to the breaking of the squall line into convective cells over the urban area. The change of precipitation amount depends on the degree of urbanization (i.e., the change over time in the extent of Beijing city). Model results show that an early urbanization prior to 1980 decreases the maximum rainfall, whereas further urbanization in Beijing is conducive to bifurcating the path of rainfall. According to sensitivity results with a single-layer urban canopy model, the thermal transport (sensible and latent heating) induced by the presence of an urban area apparently is more important than associated momentum transport, with latent and sensible heating apparently having equally important roles in the modification of simulated precipitation. Urban surfaces tend to cause the rainfall to be more locally concentrated. High-rise urban cores may bifurcate the path of rainfall as well as increase the area percentage of heavy rainfall.
