Resumo: A discussão sobre edificações sustentáveis vem sendo abordada há décadas por diferentes autores, em geral com foco no consumo energético e na vida útil dos materiais, contudo para atender esses objetivos são necessárias novas tecnologias que promovam mais sustentabilidade. Para tanto, a inclusão de fibras vegetais em compostos de solo-cimento se mostram uma alternativa interessante, e pelo fato do setor industrial madeireiro movimentar a economia local no município de Alta Floresta o resíduo serragem passa a ser um possível agregado nos tijolos ecológicos, uma vez que o armazenamento inadequado deste resíduo pode causar sérios impactos ambientais, portanto, este estudo se propôs a desenvolver um tijolo ecológico fabricado a partir da mistura de solo-cimento e serragem de três espécies florestais da Amazônia, Cambará - Vochysia sp., Cedrinho - Erisma uncinatum Warm., Garapeira. - Apuleia sp, e ainda avaliar a resistência a compressão com intervalos de cura de 7, 14, 21 e 28 dias, com o intuito de verificar a viabilidade do material construtivo. Para a realização do experimento, os tijolos foram fabricados com traço de 1:8:2,5, (cimento: solo: serragem) e a serragem utilizada com dois tratamentos, in natura e tratada por imersão e padronização granulométrica. O material misturado foi compactado em uma prensa hidráulica. Como resultado, os tijolos com serragem apresentaram valores de resistência mecânica de: Cedrinho 1,26Mpa, Cambará 1,70Mpa e Garapeira 1,95Mpa e teores de absorção de umidade  de 15,7%, 17,6% e 13,8%, respectivamente.Palavras-chave: Sustentabilidade. Tijolo solo-cimento. Serragem. Abstract: The discussion about sustainable edifications has been addressed in decades by different authors, generally focusing energetic consume and the materials lifespan, however to reach these goals it is necessary new technologies that promote more sustainability. For that the inclusion of vegetal fibers in soil-cements composts present as an interesting alternative, and because the timber industry moves the local economy in the city of Alta Floresta the sawdust residue become a possible aggregate of ecologic bricks since inadequate storage of this material can cause serious environment impacts, therefore this study propose to develop an ecologic brick manufactured by the mix of soil-cement and sawdust of three Amazonian species: Cambará - Vochysia sp., Cedrinho - Erisma uncinatum Warm, Garapeira. - Apuleia sp., and also evaluate the compression resistance in 7, 14, 21, 28 days intervals, aiming to verify the feasibility of the constructive material. To carry out the experiment the bricks were manufacture with the ratio of 1:8:2,5 (cement: soil: sawdust), and the sawdust used was treated twice, in natura, treated by immersion and granulometric standardization. The mixed material was compacted in a hydraulic press. As a result, the sawdust bricks showed resistance values of: Cedrinho 1.26 MPa, Cambará 1.70 MPa and Garapeira 1.95 MPa and humidity absorption percentage of 15.7%, 17.6%, and 13.8% % respectively.Keywords: Sustainably, Ecologic Brick, Sawdust

The main principle of the strategy for the complex improvement of the functioning of northern cities in winter, including their infrastructure development, is a comprehensive solution of the problem of industrial-scale snow-mass collection, removal and utilization at different areas of urban roadway networks. For its implementation in the capital of Russia, “MosvodokanalNIIproject” JSC developed in 2002 the Snow Removal Master Plan for the city of Moscow. The meteorological conditions in the city, which have changed considerably in the recent years, including the changes in the snow-cover depth and in the road-surface areas to be cleaned, as well as emerging of new technologies for the cleaning of urban streets, yards and sidewalks and some new types of deicing agents, resulted in the necessity to update the above-mentioned Snow Removal Master Plan developed for the city of Moscow. Efficient application of deicing agents is of special importance for its updating in the context of the environmental safety of the city in a winter period. The article considers the results of the implementation of the updated Snow Removal Master Plan and contains some proposals concerning snow removal under the conditions of extreme snowfalls.

Traditionally and socially, the tourism in Constanta is considered to be important to the local economy. Sun and beach locations are both a draw for locals and tourists to the city, on the Black Sea. However, vacation-oriented activities in the city only have a seasonal cycle. In this paper, we proposed to analyze the mass tourist activity in Constanta, taking into account economic, social, and environmental conditions. Additionally, we attempted to build a model based on the data available. The model was developed using a PESTEL analysis to determine the supportability factor of the indicators identified. We also set out to create a projection of the activities proposed for analysis by 2050. To create a model for coastal areas, the data used in this research must be accurate and consistent. Furthermore, correctly identifying indicators and their relationships is a critical step in conducting a thorough study. Last but not least, finding the calculation coefficient for the activity in question is critical, as collecting data from various activities might be challenging when trying to find a feasible model.

Open Government is committed to improving the quality of information availability on government activities, supporting civil society participation in government, upholding professional standards in public administration to prevent corruption, abuse of power and increasing access to the use of new technologies to support accountability and openness. Currently, many governments have implemented e-government which supports the government's goals in open government. Where, e-government is used to describe the use of technology in carrying out several government tasks. The city government of Palembang has several applications or e-government systems that are open government. The city government of Palembang has not made a quality measurement of the e-government that has been implemented, so it is not known the level of quality in each application or system implemented. Based on this explanation, it is necessary to analyze the level of service quality in the system that has been implemented by the Palembang City Government.

This paper is studying influence of new technologies on city development with accent on socio-spatial dimension. The primary goal of the paper is to point out the reflections of earlier ideas in the context of modern technological processes in cities. All social, technical and technological components of a community, and finally civilization, are reflected within space of the city. Although having remained the greatest consumer of many material goods, city has also become a ‘’producer’’ of many technical-technological and spiritual values of civilization. Taking into account acceleration of phenomena in the world of technology and technology featuring modernity, it reasonably brings a question on realistic chance for prediction of their further course and related social changes that are about to cause it. In many scenarios of urban future, one can sense the idea of a city as a result of high technological achievements of civilization. Special attention is paid on informational city which, connecting a lot of people into systems of interactive information technology change the way of their mutual communication, as well as their social life and culture of behaviour. Measure of organization and function of city is set by telecommunication technologies, information, and computers. If city is a ‘’print of a society in space’’, then a contemporary moment refers to ‘’digitalization’’ of human beings, digitalization of their interactions, new aesthetics, value and other criteria. The tendency of this paper is to contribute to the understanding of new technologies on 21st century cities interpreted primarily through the prism of certain theoretical and experimental ideas and concepts of the 20th century.

The article examines Muslim pilgrimages to Christian places of worship in Istanbul after the 1950s. It aims to answer whether and how the Ottoman heritage of cultural diversity fits or does not fit with the pattern of the nation-state. After a brief bibliographic overview of the issue of shared sacred spaces, the presentation assembles, as a first step, some of the key elements of Istanbul’s multi-secular links with religious practices: the sanctity of the city both for Christianity and Islam; the long tradition of pilgrimages and their importance for the local economy; meanings and etymologies of the word pilgrimage in the most common languages of the Ottoman space; and the silence of the nineteenth century’s Greek sources concerning the sharing of worship. The second part focuses more specifically on some OrthodoxGreek sacred spaces in Istanbul increasingly frequented by Muslims during the last decades.

<p class="VARAbstract">Can we preserve cultural heritage and, consequently, the memory of the past? To answer this question, one should look at the digital revolution that the world has gone through in recent decades and analyse the complex and the dialectical relationship between cultural heritage and new technologies. Thanks to these, increasingly accurate reconstructions of archaeological sites and historical monuments are possible. The resulting digital replicas are fundamental to experience and understand cultural heritage in innovative ways: they have complex and dynamic relationships with the original objects. This research paper highlights the importance and the scientific validity of digital replicas aimed at understanding, enhancing and protecting cultural heritage. The study focuses on the virtual reconstruction of the constructive phases, from the mid-15<sup>th</sup> century to date, of one of the most emblematic Gothic-Renaissance buildings in the city of Milan (Italy): the convent of Santa Maria delle Grazie, famous worldwide for hosting Leonardo da Vinci's Last Supper painting. This site proved to be an ideal case study because of its troubled and little-known history that led to numerous changes over the centuries. Thanks to a methodological approach based on the analysis of the documentary sources and three-dimensional (3D) modelling, it was possible to outline the chronological succession of the convent transformations; the way in which these overlapped the pre-existing structures was described starting from the Renaissance harmonious and organic interventions, to finally reach 18<sup>th</sup>-19<sup>th </sup>centuries inhomogeneous and incompatible additions. Finally, the research was completed by mapping the 3D models based on the sources used and their different levels of accuracy. The 3D models have thus become a valid tool for checking and verifying the reconstruction hypotheses.</p><p class="VARAbstract">Highlights:</p><ul><li><p>The study focused on the virtual reconstruction of the convent of Santa Maria delle Grazie, one of the most emblematicGothic-Renaissance buildings in the city of Milan.</p></li><li><p>By combining data from documentary sources, architectural treatises, period photos and digital survey, the mainbuilding phases of the convent, from the 15th century to date, were digitally reconstructed.</p></li><li><p>The 3D models are enriched with information about the accuracy of the digital reconstruction, creating 3D databasesthat can be easily consulted and updated.</p></li></ul>
