Abstract:
Urban agglomeration is a continuous urban spread and generally comprises a main city at the core and its adjoining growth areas. These agglomerations are studied using different concepts, theories, models, criteria, indices, and approaches, where population distribution and its associated characteristics are mainly used as the main parameters. Given the difficulties in accurately demarcating these agglomerations, novel methods and approaches have emerged in recent years. The use of geospatial big data sources to demarcate urban agglomeration is one of them. This promising method, however, has not yet been studied widely and hence remains an understudied area of research. This study explores using a multisource open geospatial big data fusion approach to demarcate urban agglomeration footprint. The paper uses the Southern Coastal Belt of Sri Lanka as the testbed to demonstrate the capabilities of this novel approach. The methodological approach considers both the urban form and functions related to the parameters of cities in defining urban agglomeration footprint. It employs near-real-time data in defining the urban function-related parameters. The results disclosed that employing urban form and function-related parameters delivers more accurate demarcation outcomes than single parameter use. Hence, the utilization of a multisource geospatial big data fusion approach for the demarcation of urban agglomeration footprint informs urban authorities in developing appropriate policies for managing urban growth.

Abstract:
The development of urban agglomerations is one of the leading modern urbanistic trends. In Russia this trend has a number of features: the "pumping" of resources, including human resources, between the agglomerations, and the rapid growth of a few agglomerations due to the degradation of the rest. Among them is the Volgograd agglomeration, which once claimed the role of the industrial, logistic and intellectual center of the South of Russia. In the context of considering this problem, the authors investigated the migration intentions of the most mobile part of the population, the student youth. The authors systematized scientific publications on the topic of research and carried out a comparative analysis of statistics from open sources and official statistics. These data were compared with the results of the monitoring of students opinions carried out by the authors in the period from 2012 to 2019. A total of 1 312 people were interviewed. The average age of respondents is 22–24 years. Analysis of students responses to the questionnaire showed that a significant part of the students would like to leave Volgograd. The volume of such answers in questionnaires grows year by year. Monitoring data revealed trends in the migration intentions of young people. According to the results of the poll, the main reasons for the intention of respondents to leave the Volgograd agglomeration are: the depressed state of the agglomeration economy and dissatisfaction with the quality of life. Comparison of the picture of students migration sentiments with Rosstat data on migration in Volgograd shows that the declared intentions of students coincide with reality. Young people from country areas of the region mainly come to Volgograd, and from the regional center they leave for other regions. The pace of development of the Volgograd agglomeration, low in comparison with other large agglomerations, leaves Volgograd little chance of improving the demographic situation in the coming years. The problem is so acute that it requires specific urgent actions and fundamental changes in the management systems of the city and urban agglomerations. The main goal of these actions should be to equalize the quality of life in the regions while adhering to the principle of diversifying regional development, taking into account the unique economic, cultural, and geographical characteristics of each agglomeration.

Abstract:
Virtual communication forms play an increasingly important role for innovation and knowledge creation to individuals and to public and private organizations such as research centers, universities, and firms. Whereas biotech R&D cooperation was characteristically organized in a highly specialized cluster based largely on local face-to-face communications and strategic temporary linkages to other agglomerations, this archetypal configuration may undergo changes due to the emerging applicability of open innovation models such as ‘open source biotechnology’ or the advanced integration of physicians and patients into therapy development processes. An in-depth case study of an ‘Open Source Pharma’ network portrays how innovation and knowledge integration mechanisms are put into practice through ´permanence` in virtual space. In this newly created environment a number of geographical patterns are inverted: ´local buzz` turns into ´virtual global buzz`; global pipelines transform to local pipelines. However, institutionalized norms of the virtual network illustrate noteworthy similarities with ´localized capabilities` of regional agglomerations.

Abstract:
Ultra High-Voltage Overhead Lines (UHV OHL) currently are successfully applied for solving two problems. The first case is powerful interconnection of two or more electric power systems. The second one is transition of significant power flows from generation areas to consuming areas – densely populated urban agglomerations and industrial centers. Longitudinal compensation installations are integral part of long-distance UHV OHL. The possibility of designing self-compensated OHL is considered in the paper.

Abstract:
In the forest zone of the European part of Russia, among the processes actively developing within most urban agglomerations, of particular importance is the process of afforestation, i.e. an increase in the area of territories with forest vegetation due to the reduction of other types of land. The Perm urban agglomeration is no exception. The replacement of part of agricultural land with forest geosystems has become a widespread process here in recent decades, as in the entire Perm region. The paper attempts to establish the scale, pace and main causes of afforestation within the agglomeration, which is done based on the example of the Babkinsko-Yugovskoy landscape, occupying the biggest part of the agglomeration. Earth remote sensing data (Landsat open satellite data) provide a large spatial and multi-temporal coverage for analyzing the landscape and obtaining qualitative data on changes in vegetation cover over several decades. Increase in the areas of restorative successions, which started in the 1990s, reached the highest values in the period from 2010 to 2020 (6,48%). This process mainly affected agricultural lands. The main natural factors of land differentiation in terms of the scale and rate of withdrawal from agricultural use are the small contours of a large part of agricultural land and difference in soil fertility.

Abstract:
The article deals with the field of knowledge about the transport behavior of passengers in complex transport systems of megacities, large cities and their agglomerations, in which there is a great variety of transport systems. These systems form hierarchies, where each level is described by mathematical models of homogeneous transport systems and serves as a decision-making area for implementing collective transport behavior. A review of the works of foreign and domestic authors dealing with the definition of the concept of “transport behavior”, its semantic content, a new approach to the definition of transport behavior is presented. The functional description of the “transport system of individual behavior” is presented as a collective result of the decisions made on trips that occur at certain time intervals in the transport system of the agglomeration. The mathematical description of the transport system based on the theory of macrosystems is given as a multicomponent heterogeneous open system, in which there are many decisions about the trip and the corresponding set of transport processes that ensure the achievement of the efficiency criterion.

Abstract:
Aim: to develop directions and determine the stages of development of intelligent transport systems in Russian agglomerations, taking into account their essential features, the effects they generate and the existing problems. Materials and Methods: in order to achieve the research goal, at the first stage, systematization and comparative analysis of scientific results obtained by Russian and foreign scientists on the chosen topic are used. At the second stage, the authors use the methods of summarizing and grouping the results obtained, statistical analysis. At the third stage, the generalization method is used to formulate recommendations for the development of intelligent transport systems. The information base of the study was materials from open sources, periodicals, as well as Internet resources, including analytical reports and materials from the Federal State Statistics Service. Results: The main scientific result is to determine the directions and stages of development of intelligent transport systems in Russian agglomerations based on the tasks they solve in the field of urban passenger transport management. In addition, a list of effects generated by the development of intelligent transport systems has been defined. The problems hindering the development of intelligent transport systems in Russian agglomerations have been identified. Conclusion: as a result of the research, the authors have formed the stages of development of intelligent transport systems, suggesting their integration with the concept of "Mobility as a service" in Russian agglomerations. The results can be used by both passenger transport companies and state executive authorities in the regions of the Russian Federation.

Abstract:
The paper presents an assessment of the development prospects and transport accessibility of organic production zones in the regions of Siberia based on data from state information systems of the Russian Federation and open information systems of commercial digital aggregators. The assessment was carried out with the use of technologies and analytics of the ArcGIS 10.6 program. The Novosibirsk, Omsk, Barnaul, and Tomsk agglomerations have concentrated clusters of investment projects for the processing of agricultural products. The eastern part of the macrozone is characterized by more focal investment activity, the largest of which is the eastern agglomeration of Krasnoyarsk. Investment projects in Kuzbass and the Irkutsk region are dispersed along the main transport routes. The republics of Altai and Tyva and the northern municipalities of the Tomsk and Irkutsk regions remain on the periphery of active transport contacts. Inside the highway part of the region there are areas of low efficiency in the use of transport potential, which makes it possible to increase the investment attractiveness of individual agricultural locations based on a combination of interspecies interaction.

Abstract:
L’étude des bâtiments en terre et bois des agglomérations du Second âge du Fer (IIIe-Ier s. av. n. è.) de Gaule interne (hors littoral méditerranéen) a permis de construire une réflexion autour de deux thématiques de recherche à la fois peu investies et complémentaires. Les nombreux débats concernant la caractérisation de ces habitats agglomérés et leur éventuel statut urbain m’ont amené à développer une approche croisée dans le cadre de ce doctorat. L’objectif a ainsi été de contribuer à une meilleure compréhension du phénomène d’urbanisation et des caractéristiques des agglomérations (oppida et agglomérations ouvertes) à travers une étude fine de l’architecture, permettant de préciser dans quelle mesure les formes architecturales sont révélatrices mais également vectrices de dynamiques socioéconomiques particulières. L’étude technique de 339 bâtiments, provenant de 39 agglomérations, s’est appuyée sur une méthodologie rigoureuse et originale. Celle-ci combine l’analyse des divers types de vestiges architecturaux et des dynamiques taphonomiques intégrant à la fois la documentation archéologique et ethnographique. Si une grande partie de ces constructions est constituée de poteaux plantés, une place privilégiée a été accordée aux architectures en pan de bois et à l’usage de pièces de contreventement obliques. Ces traditions architecturales ont ensuite été intégrées dans une recherche plus globale, considérant à la fois l’organisation spatiale des agglomérations, les usages des bâtiments et les statuts sociaux de leurs occupant·e·s, ainsi que les différences avec l’architecture rurale. Un modèle interprétatif, tenant compte du contexte environnemental et de toute la complexité de ces agglomérations, a ainsi été proposé. Une partie au moins de ces habitats groupés serait caractérisée par la mise en œuvre d’économies et de gestions rationnelles du bois d’œuvre et de la construction, par le développement de réseaux d’artisans ainsi que par des adaptations des modèles architecturaux à l’urbanisme et au degré d’urbanisation
The study of the earthen and wooden buildings of the Late Iron Age agglomerations (3rd-1st century BC) of inner Gaul (except the Mediterranean coast) allows to develop a reflection around two research topics both little invested and complementary. Many debates concerning the characterisation of these grouped settlements and their possible urban status have thus led me to develop an interdisciplinary approach in this PhD. The aim was therefore to contribute to a better understanding of the urbanisation process and of the agglomerations (oppida and open agglomerations) features through a detailed study of architecture, allowing to define how architectural forms reveal and convey particular socio-economic dynamics. The technical study of 339 buildings, from 39 agglomerations, was based on a strict and original methodology: this combines the analysis of various types of architectural remains and taphonomic dynamics integrating both archaeological and ethnographic documentation. While a large part of these constructions is made up of earthfast posts, a significant place was given to timber-framed architecture and the use of diagonal braces. These architectural traditions were then integrated into a more global research, considering at the same time the spatial organisation of agglomerations, the use of buildings and the social status of their inhabitants, as well as the differences between rural architecture and that of grouped settlements. An interpretative model, taking into account the environmental context and all the complexity of Late Iron Age agglomerations, has thus been proposed. At least part of these grouped settlements would be characterised by the development of economies and rational management of timber and construction, craftsmen networks as well as by adaptations of architectural models to urban planning and urbanisation degree

Abstract:
This paper provides a non-technical overview of NEG models dealing with policy issues. Considered policy measures include alternative categories of public expenditure, international tax competition, unilateral actions of protection/liberalisation, and trade agreements. The implications of public intervention in two-region NEG models are discussed by unfolding the impact of policy measures on agglomeration/dispersion forces. Results are described in contrast with those obtained in standard non-NEG theoretical models. The high degree of abstraction limits the applicability of NEG models to real world policy issues. We discuss in some detail two extensions of NEG models to reduce this applicability gap: the cases of multi-regional frameworks and firm heterogeneity.

Under the new economic geography framework, this study is based on the model of Tabuchi (1998), a synthesis of Alonso and Krugman, and analyzes the provision of open space in the model. We use two kinds of open space patterns, a uniformly spreading open space pattern and a pattern of central park. Three kinds of taxation including the same tax rates for each region, different tax rate for industries, and different tax rate for both regions, are used to analyze the industrial distribution being agglomeration or dispersion. Finally, we also examine the industrial distribution with the increase of households’ preference for open space for the cases of high transportation costs, low transportation costs, and zero transportation costs. Open space, as a type of public good, is different from other public goods. It has the properties of centripetal force and centrifugal force simultaneously in this model. Comparing with Tabuchi’s (1998) model, our model can reduce the centrifugal force of urban land cost and becomes the property of centripetal force. However, comparing with Anderson and Forslid’s (2003) model, our model will show the centrifugal force for a higher tax rate of open space because the open space in this model needs lands and will thus compress the land use of the households. The result of this study shows that in the case of high transportation costs and the same tax rates for each region, industrial distribution will change from dispersion to agglomeration, and then dispersion again when tax rate increases. In the case of high transportation costs and different tax rate for industries, industrial distribution will change from dispersion to agglomeration, and then dispersion again when the tax rate of manufacturing workers increases. In the case of high transportation costs and different tax rates for regions, industrial firms move to region 2 when tax rate for region 1 is lower than region 2. Industrial firms move to region 1 when tax rate for region 1 is a little bit higher than region 2, and move back to region 2 when tax rate for region 1 rises to some level. In the case of low transportation costs and the same tax rate for each region, industrial distribution will change from agglomeration to dispersion when tax rate increases. In the case of low transportation costs and different tax rate for industries, industrial distribution will change from agglomeration to dispersion, and then agglomeration again when the tax rate of agriculture workers increases. In the case of low transportation costs and different tax rate for both regions, industrial firms move to region 2 when tax rate of region 1 is much lower than or much higher than region 2. Additionally, when households’ preference for open space rises up, industrial firms will tend to agglomerate but not completely agglomerate.

Abstract:
In the presence of agglomeration economies, the effects of a rural roads programme depend not only on the reduction in transportation costs, but also on the form of labour mobility. When financed by a poll tax on rural households, the wage will rise, accompanied by some return migration, provided both cross-price effects in production and consumption and agglomeration economies are sufficiently small. With empirically plausible elasticities of agglomeration economies, urban households may be worse off. A tax on exports provides a countervailing distortion, yielding them some relief, yet with rather small adverse effects on rural households. If mobility takes the form of rural–urban commuting, cheaper fares will promote the exploitation of agglomeration economies. An export tax may then improve urban welfare. Using the change in the value, at producer prices, of the rural sector’s net supply vector as the measure of the programme’s social profitability can yield serious errors.

Abstract:
This chapter considers the in-between geography of an economy associated ever more with the consumption of signs and symbols. It also looks at the rise of a cognitive-cultural economy in the social life of commodities constructed by intermediaries and played out in arenas and considers debates over the status of the contemporary economy as primarily cognitive or cultural. The rise of brands and branding and consumption is organized in and around retail and tourism enclaves and the agglomerations that comprise our major cities. The economy between sign and symbol is a particularly hard middle ground to penetrate in analytical terms but also in normative terms. It is this economy of signs and symbols that best illustrates the strengths of post-modern analysis, but which least lends itself to clear and unambiguous policy interventions since politics and policy pronouncements are open to infinite critique for their cultural intolerance or insensitivity.

Abstract:
Agglomerations of buildings, whether just a handful in a loose settlement, or a whole town with elaborate urban infrastructures (street system, drainage, open spaces, and other ‘public works’) constitute the meso-scale, the level of the community. Remarks on the variable quality of our data sets (see chapter 2) clearly apply to what we know of the meso-scale. Unfortunately, additional parameters also limit our understanding of Minoan agglomerations, constrain interpretation and, at worst, undermine the applicability of some analytical methods. First, we are confronted with the urban palimpsest phenomenon: many settlements were occupied during very long periods of time and witnessed multiple construction phases, often very difficult to differentiate in the archaeological record. When they are not reused as foundations for later buildings, early structures are sometimes dismantled and their building materials recovered for new projects; paved streets can be maintained for centuries (Cunningham 2007; Gomrée 2013), whereas in other instances they disappear under new building programmes (Devolder et al. forthcoming; Platon 1990; see also chapter 9); and the longer and denser the occupation, the more building phases are jumbled together in intricate layouts. Of course, this tendency is not limited to Minoan times: large parts of sites like Chania and Archanes are still buried under modern towns. Although making sense of this urban palimpsest is certainly not beyond the reach of archaeologists, other factors also hinder approaches to Minoan agglomerations. In recent years, for obvious reasons, excavations have been unable to match the scope of early twentieth-century projects. Nowadays, towns like Gournia and Palaikastro could not be as extensively and rapidly excavated. This, of course, has clear positive implications but also means that, in many cases, we only have a glimpse of the overall area of settlements. Nevertheless, the same limitations often prompt very productive approaches.

Abstract:
New technological opportunities and online communication constantly gain importance for knowledge integration and knowledge creation in any innovation-driven environment. The cooperation between firms and individual actors in biotechnology was characteristically organized in local or regional clusters, based on face-to-face communications and strategic temporary linkages to other clusters. However, this archetypal configuration can change with the emerging use of open innovation models such as online research communities. A qualitative case study including an analysis of forums within an open source biomedical research platform portrays how knowledge integration mechanisms, and hence, innovations are implemented in virtual space. In this newly created environment, a number of geographical patterns are inverted: The strong role of physical co-location is partly substituted by enabled online proximity and new opportunities of virtual “prototype-sharing”; the former global pipelines are transformed to local and virtual cross-community pipelines. Yet mechanisms of creating social coherence and stability illustrate noteworthy similarities with “localized capabilities” of regional agglomerations. Eventually, knowledge integration capabilities ensure that the network can operate as a successful knowledge provider.

Abstract:
Public spaces can be considered as important elements to improve the quality of the environment and increase the sense of citizenship. On the other hand, the cohesive network of urban spaces shows the integrated structure of a city’s spatial organization, in which not only the connection of form and function is considered, but also meaning finds its place in a complex urban system. Since the spatial structure of the traditional Iranian cities is ingrained in geographical factors and culture of the settlements, the evolution of this structure in Isfahan as one of the most famous historical cities in Iran is examined. The aim of this study is to answer this question: How do urban open spaces impact city spatial structure? The research method is descriptive-analytical, which has been concluded in a process of content analysis. The development of Isfahan’s structure over time and role of urban spaces in its formation has been studied. Entrances, key points, roads, and water edges as main urban spaces impact on city structure direction. The structure has changed from linear-nuclei to central-radial and finally, an integrated network to the Safavid era, but cohesive nature of the structure has changed from the Pahlavi period with multiple sections of streets.

Abstract:
In this chapter, a framework for assessing the openness of virtual archaeological reconstructions to a multiplicity of readings is presented by focusing on the case of Çatalhöyük, in Turkey. Since its discovery in the 1950s, there has been a diversity of opinion on Çatalhöyük’s settlement rank along the path from settled village to urban agglomeration. This diversity of opinion has been expressed both verbally and visually, the latter including numerous computer-based visualizations for a variety of purposes and target audiences. Among the internationally approved principles for computer-based visualizations of cultural heritage is the need for intellectual and scientific transparency. Umberto Eco’s theory of the “open work,” as applied in literary and visual works including motion pictures, offers a theoretical framework for discussing the transparency of Çatalhöyük visualizations, as does Siegfried Kracauer’s idea of “cinematic materiality.” Three of the virtual works on Çatalhöyük are briefly presented in this chapter, as a basis for discussing the applicability of Eco’s and Kracauer’s ideas in this type of production as a measure for “open multivocality,” leading to an assessment of whether visualizations reveal any or all alternative interpretations of the site.

This chapter will analyze Argentinean structures and patterns of interaction observed at the regional level in applied terms from the perspective of lagging regions. For reasons of space, the emphasis is on the geographic structure of the population and its dynamics. The subjection of aspects of the center-periphery relationship also forms part of the discussion. This discussion takes place within the already unbalanced Argentine macro-fiscal context, which generates uneven capacities and structures to absorb and deal with aggregated dynamics. The main characteristics of the regional and urban structure are defined through a series of fundamental variables, such as population, centrality, and diversity.

Abstract:
This chapter examines India’s urbanization and urban system. It shows that urbanization in India continues to be driven by natural increase and reclassification of rural settlements into urban, with rural-to-urban migration playing, at best, a modest role in the urbanization process. Recent economy-wide shifts including higher economic growth have made little impact on either the pace or the structure of urbanization, which continues to be dominated by a large number of small towns and a small number of large cities. India’s urban system displays neither primacy nor does it conform to the rank-size distribution. Upper-tail cities are not large enough to fit into the rank-size distribution and the populations of the lower end are smaller than the predicted values, raising questions about their capacity to generate scale and agglomeration economies. Marked variations are observed in urban systems across states. This chapter emphasizes the need for further research to help understand the urban systems of India’s federal structure.

Abstract:
This chapter examines national science policy as a case-study in evidence-based policy design. Its reviews the strategy and science of Irish science policy in light of the challenges for such policies in an SOE. The success of knowledge intensive industries depends on access to knowledge. However, private firms tend to underinvest in basic science where much of the benefit spills over to other firms, highlighting an important role for governments. Governments of SOEs face two challenges in devising a strategy for science policy: first, the benefits of science investments are likely to flow disproportionately to other countries; second, small size may limit the benefits of agglomeration economies that are central to many knowledge-intensive industries. Despite obvious spillover and scale challenges – geographical stickiness of new knowledge production and the capacity to absorb knowledge from the global stock depends on being active at the frontiers of knowledge production. The chapter concludes that the national benefit of research is the advantage in being able to access knowledge produced elsewhere.

"impeller and the stationary housing. Many ingenious designs are available that use various configurations with the purpose of increasing the probability that the solid par-ticles or liquid droplets travel through the rotor/stator zones where maximum shearing occurs. Almost all designs have some form of teeth or blades, which are meshed into an accompanying stationary housing as illustrated in Fig. 28. Of particular importance is the fact that, when a mixture containing solid particles or agglomerations or emulsion droplets is pumped through a fixed gap rotor/stator mixer, not all of the droplets or particles pass through the highest shearing zones. Some par-ticles passing through the machine may escape the rotor/stator gaps and be exposed only to some of the lower shear zones. The more open the design of the rotor/stator, the Fig. 28 Internal parts of rotor/stator mixer showing meshed teeth. (From Ref. 31.)." In Pharmaceutical Dosage Forms, 357.

Abstract:
When a system evolution is not planned, developers can take decisions that degrade the system quality. To cope with this problem, refactoring can be applied to the source code aiming to increase code quality without modifying the software external behavior. To know when to refactor, the concept of bad smells can be used. Bad smells are snippets of source code that suggest the need of refactoring. However, bad smells does not always appear isolated. The aim of this study is to understand the impact of bad smell agglomerations on the software quality by evaluating a large dataset of open source systems. To achieve our goal, we plan to use data mining techniques complemented with correlation analysis of the dataset.

Abstract:
Cartographying the real metropolis: A proposal for a data-based planning beyond the administrative boundaries. Juan R. Selva-Royo¹, Nuño Mardones¹, Alberto Cendoya² ¹University of Navarra, School of Architecture, Department of Theory and Design, University of Navarra Campus, 31080 Pamplona, Spain; ²University of Navarra, ICS, Navarra Center for International Development, University of Navarra Campus, 31080, Pamplona, Spain E-mail: jrselva@unav.es, nmardones@unav.es, cendoya.alberto@gmail.com Keywords (3-5): Data planning, metropolitan areas, big data, urban extent, good governance Conference topics and scale: Cartography and big data Nowadays, there is a great gap between the functional reality of urban agglomerations and their planning, largely because of the traditional linkage of urban management to the administrative limits inherited from the past. It is also true that the regulation of urban activities, including census and statistical information, requires a closer view of its citizens that can only be addressed from the municipal level. In any case, it is clear that the metropolitan delimitation has met useful but often ethereal or exclusionary criteria (economic or labor patterns, functional areas...), which become disfigured by an administrative reality that does not always correspond to the real metropolis. This paper, aware of the new cartographic possibilities linked to the big data - CORINE Land Cover, SIOSE, multi-sector digital atlases (in many cases referred to the urban extent, etc.) and other open system platforms - explores the evidence that might base a new objective methodology for the delimitation and planning of large urban areas. Indeed, what if basic data for cities would arise not from administrative entities but from independent outside approaches such as satellite imagery? What if every single sensing unit (every citizen, company, building or vehicle) directly issued relevant and dynamic information without going through the municipal collection? Finally, the research analyzes the eventual implications of this data-based planning with administrative structures and urban planning competencies in force through some current case studies, with the purpose of achieving a more efficient and clear metropolitan governance for our planet.

Abstract:
Abstract The typical solution in the cement industry to respond to the application challenges is the use chemical additives to adapt cement characteristics to the scenario. However, this approach may weaken cement integrity especially in long term. The use of physical properties to obtain similar performance may be a new frontier as cement can be kept without changes and the new additives are inert to the mixture. A proof of concept study was carried out on using magnetic nanoparticles (MNP) and an oscillating magnetic field source to replace chemical additives in the objective of reducing Waiting on Cement (WOC) time during cementing operations in oil and gas wells. A rigorous process was executed to select the most promising particles and several experiments testing different cement slurries designs were executed to confirm the feasibility of this patented technology. Magnetite nanoparticles were blended in 15.9 ppg class G Portland cement slurries in amounts of 0.25% and 0.50% by weight of cement (BWOC). The slurries were cured in atmospheric conditions up to seven days and characterized to determine the influence of the nanoparticles on early age compressive strength development and microstructural properties. Compressive strength development was tested both by destructive testing and by ultrasonic cement analyzer (UCA). Microstructural properties were determined by isothermal calorimetry, scanning electron microscopy, X-ray diffraction and thermogravimetric analysis. Destructive testing of samples cured at atmospheric conditions up to 168 hours showed that the use of magnetic nanoparticles did not affect the compressive strength of cement. UCA experiments, carried out in temperatures similar to those obtainable by magnetically induced heating, confirmed the potential of the technology to accelerate strength development. Isothermal calorimetry results showed that the presence of MNP did not interfere with the normal hydration reaction of cement, fact that was confirmed by the thermogravimetric analyses, where the amount of hydration products was found to be similar for all samples. Scanning electron microscopy imaging showed MNP agglomerations in the pores of cement slurry, which might compromise their heating potential. X-ray diffraction showed the formation of ettringite in all samples. It was concluded that the presence of MNP in the cement slurry was not found to be detrimental to the mechanical and microstructural properties, which open a new frontier to the use of free-additive cement slurries, a cheaper solution built with components where the degradation along the life is well understood, in the opposition to the chemical additives, which degrade faster than cement by itself especially in long term such as well abandonment and carbon storage applications (CCS).

Abstract:
This paper reports on how journal articles are presented within the Open Language Archive Community’s (OLAC) OAI-PMH aggregator for language resources. It discusses metadata record composition across data providers. The conceptual category of "Language resource" is a broad agglomeration including original creative works captured in handwritten, audio, and video mediums, annotations to the raw captures, and analysis of those annotations. Discovery of language resources is a challenge given the diversity of resource origins. Original creative works and annotations are products often available via archives while analysis, theory, and advice are often released via formal publishing venues such as journals. Scholars benefit from a view where resources from various release sources can be displayed with their inter-resource relationships, e.g., source material and analysis. Understanding how secondary journal materials are presented in OLAC records is a first step towards increasing the end-user utility of the OLAC aggregator.

Abstract:
In this study an academic CFD code, named Galatea-I, is presented, capable for simulating inviscid, viscous laminar and viscous turbulent incompressible fluid flows. It employs the RANS (Reynolds-Averaged Navier-Stokes) approach along with the SST (Shear Stress Transport) turbulence model to predict turbulent flow phenomena, such as recirculations and separations of flow, on three-dimensional unstructured hybrid grids, composed of prismatic, tetrahedral and pyramidal elements. Discretization of the governing equations is obtained with a node-centered finite-volume scheme. Parallel processing and agglomeration multigrid scheme are implemented for the acceleration of the numerical process. As the title of this paper reveals, the solver is validated against the test cases of the DARPA SUBOFF program; in particular, flows over the SUBOFF bare hull submarine geometry at two incident angles and the SUBOFF hull with fairwater configuration are examined. The obtained results, compared to available in open literature experimental data as well as results computed by reference solvers, indicate the proposed methodology’s potential to accurately simulate complex fluid flows.

Abstract:
In this paper we explore the possible impact of urban congestion on agglomeration economies for a cross-section set of cities in Latin America. We use travel time data from Tom Tom to estimate wage regressions equations controlling for city size and congestion. We use population in each city in the 19th and early 20th century as instruments for current city size (measures by population). In our baseline estimates, we find an elasticity of wages to city size of 0.05, very similar to previous research in the region. When congestion is included in the estimation, we find that agglomeration economies are reduced. This holds even after using rain-days and average yearly as an instrument for congestion. Our results imply that congestion is a drag on economic productivity. This indirect cost of congestion is considerably larger economically than the direct cost measured as the loss of valuable time for citizens.

Abstract:
Creative industries are considered highly innovative and productive, constituting an important driver of economic change. For high-income countries, several studies discuss the positive spillovers of creative industries for the local economy, for instance by attracting creative workers, which can benet entrepreneurs and workers in other industries. Like many other activities, creative industries are likely to dier in low- and middle-income countries compared to high-income countries. Moreover, the existing evidence is based on correlations between variables likely to be endogenous. This paper contributes to the literature on the role of creative industries in driving economic change in two main ways. First, we make a rst attempt to control for endogeneity and identify the impact of creative industries on local economies. Second, we report evidence for a middle-income country. Using granular employment data, we study the agglomeration patterns of creative industries across Colombian cities between 2008 and 2017. Exploiting the co-location of creative industries with other industries, we estimate the relation between employment growth in creative and non-creative industries in the same city. Using a shift-share instrumental variable approach, we estimate the multiplier eect of employment growth in creative industries on the employment growth in the rest of the economy. Creative industries represented between 2.7 and 3.3 percent of Colombian employment in 2008 and 2017. We nd that creative industries agglomerate mainly in three large cities (Bogota, Medelln, and Cartagena) and in a few smaller cities. Such agglomeration is positively related to an increase in the employment of non-creative services industries. For a positive causal relation to materialize, creative industries should have a larger size or be more connected to other economic sectors. However, after controlling for endogeneity, we nd no signicant impact of an increase of creative industries employment on employment growth in other industries.
