Informational Techniques for Urban Sciences

Different attributes are responsible for shaping the characteristics of a city. Effective characterization and monitoring of a city needs a strong understanding of the working of these attributes. That means there is a need of multidimensional data about these attributes for effective characterization of the city. However, there is a possibility that a huge amount of data would be generated in the process of characterizing the working of the city. In addition, it has to be understood that the data need to be studied using some scientific principles. Otherwise, it would not be possible to extract some meaningful information from the data. Therefore, this chapter aims to explain the significance of informational techniques in extracting meaningful information from the data. Having read this chapter, reader will understand the significance of application of proper informational technique investigations related to urban sciences.

AbstractDengue virus is a major and rapidly growing public health concern in tropic and subtropic regions across the globe. In late 2018, Senegal experienced its largest dengue virus outbreak to date, covering several regions. However, little is known about the genetic diversity of dengue virus (DENV) in Senegal. Here we report complete viral genomes from 17 previously undetected DENV cases from the city of Thiès. In total we identified 19 cases of DENV in a cohort of 198 individuals with fever collected in October and November 2018. We detected 3 co-circulating serotypes; DENV 3 was the most frequent accounting for 11/17 sequences (65%), 4 (23%) were DENV2 and 2 (12%) were DENV1. Sequences were most similar to recent sequences from West Africa, suggesting ongoing local circulation of viral populations; however, detailed inference is limited by the scarcity of available genomic data. We did not find clear associations with reported clinical signs or symptoms, highlighting the importance of testing for diagnosing febrile diseases. Overall, these findings expand the known range of DENV in Senegal, and underscore the need for better genomic characterization of DENV in West Africa.

AbstractIn this paper are presented the studies of the paint materials and the technique used in 18th century wall paintings, originated from the orthodox church of St Athanasius, in the city of Maschopolis, a flourishing economical and cultural center, in Albania. The church was painted in 1745 by Konstantinos and Athanasios Zografi, and during the last years, restoration activities are being performed at the church. Samples that included plasters and pigments of different colors were collected from important points of the wall paintings. Additionally, as some parts of the wall-paintings were over-painted, the analysis was extended to the compositional characterization of these areas. The identification of the used materials was done by using complementary analytical methods such as Optical Microscopy, Fourier Transform Infrared spectroscopy (FTIR), Scanning Electron Microscopy (SEM-EDS) and X-ray fluorescence (TXRF).The presence of calcite in almost all the pigments is indicative for the use of the fresco technique at the studied areas, while the detection of gypsum and calcium oxalate, indicates an environmental degradation along with a biodegradation. Common pigments used in this area at 15-16th centuries, such as cinnabar, green earth, manganese oxide, carbon black and calcite were identified.

In the last decade, in the mining district of Zaruma-Portovelo, there has been significant land subsidence related to uncontrolled mining activity. The purpose of this work was to carry out a surface and underground geomechanical characterization of a mining sector north of the city of Zaruma that allows the definition of potentially unstable areas susceptible to the mass movement. The methodology used consists of the following stages: (i) compilation of previous studies; (ii) surface and underground characterization of rocky material to establish its susceptibility to mass movement; (iii) interpretation of results; and (iv) proposal of action measures. Among the most relevant results, it stands out that 26.1% of the 23 stations characterized on the surface present conditions that vary from potentially unstable to unstable. In underground galleries, the studied mean values of the 17 stations indicate that the rock has a medium to good quality, representing a medium susceptibility to gallery destabilization. The results obtained for the surface areas (depths up to 50 m, where altered materials predominate) and the underground areas (depths > 50 m, where the alterations are specific) can be used to identify the areas with a more significant potential for instability. For both cases, it has been possible to define specific monitoring, control, and planning actions for sensitive areas.

Abstract Many housing estates of social interest have not contributed to implementing leisure areas and reducing their environmental and urban quality. This paper aims to propose a leisure unit using a compensatory urban drainage technique in a housing complex of social interest in the city of São José do Rio Preto, São Paulo, Brazil. The characterization of the area, land use and occupation surveys, area sectorization, and catchment division were carried out. Afterwards, proposals for interventions based on surface runoff were presented using calculations of existing runoff and future scenarios. Results related to environmental and social gains for the area are discussed, as well as the possibility of implementing decentralized compensatory techniques. Moreover, 156 rain gardens and 3 ditches were proposed throughout the subdivisions, which enabled a gain of 989m² of contribution area to infiltrate the whole area, and the use of the retention basin as a leisure area. The total storage volume achieved with the sum of all the techniques implemented was approximately 3,000 cubic meters more than that projected for the existing retention basin.

Narratives of traumatic citizenship not only raise questions about the past, but also they give voice to contemporary stories about this past. In post-apartheid South Africa, these questions, markers of apartheid temporality, are embodied in, among other sites, the representation of battered Black bodies in cinema. This article critiques the characterization of Blacks as narrative spaces to illustrate the temporality of distress and trauma from apartheid to post-apartheid Johannesburg in Gavin Hood’s Tsotsi. It argues that the film posits Black characters as latent archives of intergenerational historical narratives that probe the apartheid past and speculate on the post-apartheid future in the city of Johannesburg. Consequently, the juxtaposition of embodied narrative archives and apartheid temporality, the article posits, is a crucial model in the theorization of battered Black bodies’ contiguous nostalgia.

Abstract At the center of Plato’s Gorgias, the shameless and irascible Callicles offers an attack against philosophy (484c and following). During this attack, he describes philosophy as a pastime fit only for the young which, if practiced beyond the bloom of youth, threatens to render those who practice it politically inept and powerless. Moreover, when taken too far, philosophy provokes the city into stripping the philosopher of all of his rights and property, leaving him with no οὐσία at all (486c). Thus, according to Callicles, far from making one powerful within the city, philosophy ultimately renders one impotent and utterly without substance. In what follows I argue that the Socrates of the Gorgias agrees with this characterization of the philosopher as the one who lacks power and οὐσία. However, whereas Callicles sees such a condition as the most worthless and pitiable sort, Socrates sees it as the unique and singular posture from out of which true philosophical thinking, and true political power, are possible. As I will show, through the course of the Gorgias as a whole, Socrates offers a counter-discourse that presents the philosopher as a powerless person lacking οὐσία who is precisely thereby able to undertake a pursuit of the truth and the good. Phrased otherwise: Socrates takes ignorance understood as lack or powerlessness to be the very condition for the possibility of philosophy and true political power, while showing rhetoric understood as the pretense of wisdom to be an obstruction to these.

In recent years, one type of alumina rich fly ash (ARFA) with about 50 wt% of alumina has been extensively investigated for alumina extraction in China. Due to the silica in ARFA, alumina extraction would have to generate a huge amount of solid waste. There is a growing interest in the glasses in ARFA, because they are composed mainly of silica and could be removed prior to alumina extraction. In this work, the glasses in ARFA have been investigated by chemical methods, that is, acid and base digestions. The chemical compositions have been measured by XRF for ARFA from the digestion processes. The K2O standard, XRD, and FTIR spectroscopies were successfully used to define the digestions processes, and size analysis and SEM-EDX provided rich information on particle transformations. As a result, acid and base digestion methods were found to produce very similar results for the glasses in ARFA. The K2O standard was attributed to the formation of glasses by illites, and TiO2and Fe2O3were proposed to originate from ilmenite in alumina rich coals (ARC). Some implications of the results were also discussed for the alumina extraction from ARFA.
