Authors: Trimborn Lisa , Farkas Luca , Glückler Ramesh , Gloy Josias , Herzschuh Ulrike , Kruse Stefan
Published: January 2024

Boreale Wälder speichern 32% des globalen Kohlenstoffs. Klimatische Veränderungen wie beispielsweise von Temperatur, Niederschlag, solarer Strahlung und CO₂-Konzentration in der Atmosphäre verändern die Physiologie der Bäume und haben somit einen Einfluss auf die Widerstandsfähigkeit gegen Störungen. Insekten als eine Art von Störung reagieren ebenfalls auf veränderte Temperaturen oder Niederschläge und könnten häufiger und stärker die Bäume schädigen.
Wir wollen herausfinden, wie sich die borealen Wälder Alaskas unter dem Klimawandel und unter veränderten Störungen entwickeln könnten. Konkret geht es darum, wie sich Klimaveränderungen auf das Auftretenvon Insekten auswirken und wie Insekten wiederum die Baumbiomasse beeinflussen.
Hierfür erweitern wir das bereits vorhandene Modell LAVESI (Larix Vegetation Simulator) um sieben weitere Baumarten und um die Region Alaska. So können wir zukünftige Baumbiomasse unter verschiedenen Klimaszenarien simulieren. Danach berechnen wir aus vorhandenen Datensätzen für sieben verschiedene Insektenarten statistische Wahrscheinlichkeiten für ihr Auftreten und für den Schweregrad des Befalls unter bestimmten Temperatur- und Niederschlagsbedingungen in Alaska. Mit diesen Informationen lassen sich zukünftig von Insekten befallene Waldflächen unter verschiedenen Klimaszenarien modellieren.
Wir kombinieren beide Modelle mit Daten über die Auswirkungen der Insekten auf die einzelnen Baumarten (z.B. Entlaubung oder Mortalität). Daraus lässt sich dann errechnen, wie Einzelbäume in Beständen und schließlich die Biomasse der einzelnen Baumarten in Zukunft unter Einfluss des Klimawandels und der durch den Klimawandel beeinflussten Insekten entwickeln wird. Außerdem wird sichtbar werden, welche Baumarten in Zukunft in Alaska unter veränderten Klimabedingungen und unter verändertem Insektenauftreten zu erwarten sind.
How bad is it if adaptation decisions are influenced by typical climate attribution results? On the link between time of emergence and the crossing of adaptation-relevant hazard thresholds
Authors: Aglas-Leitner Philipp , Undorf Sabine
Published: January 2024

Most common climate-scientific attribution studies check for, or quantify, the influence of combined anthropogenic climate forcing to date on an observed change or event. Besides fulfilling a range of well-evidenced roles in society, attribution findings are also commonly quoted together with calls specifically for, or even financial prioritisation of, climate change adaptation to the respective climate hazard in the respective region. Notions of adaptation deservedness as well as differentiated availability and applicability of scientific data and tools and other practical issues contraindicate this conclusion. More fundamentally, it also hinges on the degree to which the emergence of an anthropogenic change signal in observations to date is indicative of future climate hazards relevant to adaptation.
Here, we address this question by analysing the link between selected hazards’, or climatic-impact drivers’, Time of Emergence on the one hand, and the exceedence of adaptation-relevant relative and absolute thresholds on the other hand, at subcontinental scales globally. Time of emergence is defined following common standards in the recent literature; climatic-impact drivers (heat and cold, wet and dry) are chosen based on the latest IPCC report; thresholds relevant for adaptation in different impact sectors are refined based on expert judgment in interdisciplinary cooperation. The analysis is performed on large-ensemble climate model data from CMIP6’s Detection and Attribution (DAMIP) and Scenario Model (ScenarioMIP) Intercomparison Projects and observational climate data consulted for reference.
Our results show the globally differentiated error that is made when drawing a direct link between a typical climate-scientific attribution results and adaptation-relevant climate change. Factors contributing to this complexity include changes in anthropogenic non-greenhouse gas climate forcings, spatially differing internal climate variability, and present-day climatology, for example. We acknowledge methodological caveats, draw further implications for climate justice and global adaptation, and discuss the potential of additional climate projection-based evidence for effective communication.
Down-scaling and bias correction of precipitation with generative machine learning models
Authors: Aich Michael , Pan Baoxiang , Hess Philipp , Bathiany Sebastian , Huang Yu , Boers Niklas
Published: January 2024

Earth system models (ESMs) are crucial for understanding and predicting the behaviour of the Earth’s climate system. Understanding and accurately simulating precipitation is particularly important for assessing the impacts of climate change, predicting extreme weather events, and developing sus- tainable strategies to manage water resources and mitigate associated risks. However, earth system models are prone to large precipitation biases because the relevant processes occur on a large range of scales and involve substantial uncertainties.In this work, we aim to correct such model biases by training generative machine learning models that map between model data and observational data. We address the challenge that the datasets are not paired, meaning that there is no sample-related ground truth to compare the model output to, due to the chaotic nature of geophysical flows. This challenge renders many machine learning approach unsuitable, and also implies a lack of performance metrics.
Our main contribution is the construction of a proxy variable that over- comes this problem and allows for supervised training and evaluation of a bias correction model. We show that a generative model is then able to 

correct spatial patterns and remove statistical biases in the South American domain. The approach successfully preserves large scale structures in the climate model fields while correcting small scale biases in the model data’s spatio-temporal structure and frequency distribution.
Systematische Fehler in der Definition von Temperaturextremen und ihre Auswirkungen
Authors: Brunner Lukas , Voigt Aiko
Published: January 2024

Immer stärkere Hitzeextreme gehören zu den gravierendsten und meistdiskutierten Auswirkungen des menschengemachten Klimawandels. Solche Extreme werden oft relativ zur lokalen Temperaturverteilung definiert, zum Beispiel als Überschreitung eines bestimmten Perzentils, das oft mit Hilfe eines gleitenden Fensters (engl. running window) entlang des Jahresganges berechnet wird. Ein solcher Ansatz berücksichtigt die Anpassung von Umwelt und Gesellschaft an lokale Gegebenheiten und soll Vergleiche von Extremen zwischen Regionen und Datatenstäzen sowie ein Auftreten von Hitzeextremen auch außerhalb des Sommers ermöglichen.
Implizit wird dabei angenommen, dass eine Definition von Extremen zum Beispiel als Überschreitung des 90 Perzentils dazu führt, dass Extreme mit einer mittleren Häufigkeit von ca. 10% auftreten, unabhängig von Region, Jahreszeit und Datensatz. Wir zeigen, dass diese in der wissenschaftlichen Litaratur regelmäßig getroffene Annahme nicht korrekt ist. Abhängig von der Weite des verwendeten gleitenden Festers, kann die Frequenz der Überschreitung des 90 Perzentils weniger als 5% betragen, was einem relativen Fehler von 50% entspricht. 
Da dieser Fehler auf die Stärke der jahreszeitlichen Schwankungen zurückzuführen ist, tritt er systematisch auf. Er kann zu unerwarteten Ergebnissen und zu einer falschen  Interpretationen der Extremfrequenz in verschiedenen Kontexten führen, zum Beispiel: 

Extreme treten aufgrund des Fehlers nicht in allen Jahreszeiten mit der gleichen Wahrscheinlichkeit auf. Typischerweise werden sie in der warmen Jahreszeit leicht überschätzt, in der kalten Jahreszeit leicht unterschätzt und in den Übergangszeiten stark unterschätzt.
Vergleiche von Extremen (und abgeleiteten Größen wie Hitzewellen) zwischen Regionen sind nicht fair, wenn sich der Fehler und damit die Wahrscheinlichkeit des Auftretens von Extremen regional unterscheidet.
Vergleiche von Datensätzen mit unterschiedlicher Fehlerstruktur können zu künstlichen Unterschieden führen, die fälschlicherweise als Klimamodellfehler (im Vergleich mit Beobachtungen) interpretiert werden können, obwohl sie tatsächlich auf einen Methodenfehler zurückzuführen sind.

Abbildung: Relativer Fehler in der Frequenz von Hitzeextremen basierend auf täglichen Daten von ERA5 im Mittel von 1961-1990. Extreme sind als Überschreitung des 90 Perzentils für jeden Tag im Jahr definiert, die Berechnung des Perzentils verwendet ein gleitendes Fenster über 31 Tage. Der Fehler ist die relative Abweichung von den erwarteten 10% Extremen.
Aerosol layer height (ALH) retrievals from oxygen absorption bands: Intercomparison and validation among different satellite platforms, GEMS, EPIC, and TROPOMI

Published: January 2024

Abstract. Although containing only single piece of information, aerosol layer height (ALH) indicates the altitude of aerosol layer in vertical coordinate which is essential for assessment of surface air quality and aerosol climate impact. Passive remote sensing measurements in oxygen (O2) absorption bands are sensitive to ALH, providing an opportunity to derive global or regional ALH information from satellite observations. In this study, we compare ALH products retrieved from near-infrared O2 absorption measurements from multiple satellite platforms including Geostationary Environment Monitoring Spectrometer (GEMS) focusing on Asia, Earth Polychromatic Imaging Camera (EPIC) in deep space, and polar orbiting satellite TROPOspheric Monitoring Instrument (TROPOMI), and validate them using spaceborne lidar (CALIOP) measurements for typical dust and smoke plumes. Adjustments have been made to account for the inherent variations in the definitions of ALH among different products, ensuring an apple-to-apple comparison. In comparison with CALIOP ALH, both EPIC and TROPOMI ALH display a high correlation coefficient (R) higher than 0.7 and an overestimation by ~ 0.8 km, whereas GEMS ALH exhibits minimal bias (0.1 km) but a slightly lower correlation with R of 0.64. Categorizing GEMS retrievals with UVAI ≥ 3 improves the agreement with CALIOP. GEMS ALH demonstrates a narrower range and lower mean value compared to EPIC and TROPOMI, and their correlation is further improved when UVAI ≥ 3. Furthermore, diurnal variation of GEMS and EPIC ALH, especially for UVAI ≥ 3, aligns with boundary layer development. Considering the important role of AOD in ALH retrieval, we found GEMS AOD at 680 nm correlates well with AERONET AOD (R ~ 0.9) but features a negative bias of -0.2. EPIC and TROPOMI tend to overestimate ALH by 0.33 km and 0.23 km, respectively, in dust cases. Finally, a dust and a smoke case are analysed in detail to explore the variation of ALH during plume transport from multiple data.
Insights from topo-bathymetric and oceanographic dataset for coastal flooding studies: The French Flooding Prevention Action Program of Saint-Malo

Published: January 2024

Abstract. The Action Program for Flood Prevention of Saint-Malo, France, requires the assessment of coastal flooding risks and the development of a local flooding warning system. The first prerequisite is a knowledge of the topography and bathymetry of the bay of Saint-Malo; the acquisition of new multibeam bathymetric data was performed in 2018 and 2019 to densify existing topo-bathymetric datasets and produce two high resolution (20 m and 5 m) topo-bathymetric digital terrain models. Second, the hydrodynamics associated with coastal flooding were investigated through a dense and extensive oceanographic field experiment conducted during winter 2018–2019, using a network of 22 moorings with 37 sensors : the network included 2 directional buoys, 2 pressure tide gauges, 18 wave pressure gauges, 4 single-point current meters, 7 current profilers and 4 acoustic wave-current profilers from mid-depth (25 m) up to the upper beach and the dike system. The oceanographic dataset thus provides an extended overview of hydrodynamics and wave processes in Saint-Malo bay, from coastal up to over-flooding and over-topping areas. It helps to identify the physical drivers of the coastal flooding, and provides a quantification of their respective contributions. In particular, the wave processes at the foot of the protection structures can be observed: in this macrotidal environment, during high spring tides, short and infragravity waves propagate up to the protection structures, while the wave set-up remains negligible, and overtopping by sea packs can occur. The combination of high-resolution topo-bathymetric and oceanographic datasets allows the construction, calibration and validation of a wave and hydrodynamic coupled model that is used to investigate more deeply flooding processes, and might be integrated in a future local warning system by Saint-Malo intercommunality. The topo-bathymetric and oceanographic datasets are available freely at doi: https://doi.org/10.17183/MNT_COTIER_GNB_PAPI_SM_20m_WGS84, https://doi.org/10.17183/MNT_COTIER_PORT_SM_PAPI_SM_5m_WGS84 and https://doi.org/10.17183/CAMPAGNE_OCEANO_STMALO (SHOM, 2020a, b, 2021).
Meeting a need: development and validation of PubMed search filters for immigrant populations
Authors: Wafford, AHIP Q. Eileen , Miller Corinne H. , Wescott Annie , Kubilius, AHIP Ramune K.
Published: January 2024

Objective: There is a need for additional comprehensive and validated filters to find relevant references more efficiently in the growing body of research on immigrant populations. Our goal was to create reliable search filters that direct librarians and researchers to pertinent studies indexed in PubMed about health topics specific to immigrant populations.
Methods: We applied a systematic and multi-step process that combined information from expert input, authoritative sources, automation, and manual review of sources. We established a focused scope and eligibility criteria, which we used to create the development and validation sets. We formed a term ranking system that resulted in the creation of two filters: an immigrant-specific and an immigrant-sensitive search filter.
Results: When tested against the validation set, the specific filter sensitivity was 88.09%, specificity 97.26%, precision 97.88%, and the NNR 1.02. The sensitive filter sensitivity was 97.76%when tested against the development set. The sensitive filter had a sensitivity of 97.14%, specificity of 82.05%, precision of 88.59%, accuracy of 90.94%, and NNR [See Table 1] of 1.13 when tested against the validation set.
Conclusion: We accomplished our goal of developing PubMed search filters to help researchers retrieve studies about immigrants. The specific and sensitive PubMed search filters give information professionals and researchers options to maximize the specificity and precision or increase the sensitivity of their search for relevant studies in PubMed. Both search filters generated strong performance measurements and can be used as-is, to capture a subset of immigrant-related literature, or adapted and revised to fit the unique research needs of specific project teams (e.g. remove US-centric language, add location-specific terminology, or expand the search strategy to include terms for the topic/s being investigated in the immigrant population identified by the filter). There is also a potential for teams to employ the search filter development process described here for their own topics and use.

Published: January 2024

“Metaverse” is the idea of a shared virtual environment that is “parallelized” to the real world thanks to advances in technology. The metaverse world is currently not only used as a platform for playing games but has also been used as a place for doing business. The purpose of this research is to identify articles that study the metaverse in marketing and provide an overview of the Metaverse knowledge domain as a new marketing world and to show and explain the research mapping. This mapping will help researchers explore and develop research related to the metaverse as a new marketing world landscape. Marketing is a promotional activity that can attract consumers to increase sales. Metaverse is a virtual universe that imitates real world procedures. In this 3D virtual environment, users can carry out activities in the digital world like in the real world, as is done with the Gucci brand which uses the metaverse as a marketing medium based on blockchain TheSandbox. This will have a major impact on how companies implement marketing in the future and how people communicate with each other. In Industry 5.0, metaverse has entered the world of marketing and has begun to be used by several companies. So, metaverse becomes a new world in marketing. This research uses qualitative methods with bibliometric techniques by utilizing Visualization of Similarities (Vosviewers) as an application. By entering keywords such as Metaverse; Metaverse marketing; Digital Marketing; New Marketing Universe; Gen z to search for articles via Publish or Perish with a total of 940 articles which were then processed using VosViewers. The results of the analysis found scientific mapping and possible future studies regarding the metaverse as a new marketing world that can be used as variable recommendations for future researchers as a reference for subsequent articles.

A FACE POLÍTICA DO SISTEMA MINEIRO DE ADMINISTRAÇÃO ESCOLAR: OS IDEAIS DO ESTADO CONFIGURADOS EM INTERFACES
Authors: Lima Carla da Conceição de
Published: January 2024

Este artigo tem o objetivo de analisar a face política do Sistema Mineiro de Administração Escolar (SIMADE) a partir da associação entre as interfaces e os princípios educacionais emanados pelo Estado de Minas Gerais no período de 2008 a 2018. Trata-se de uma pesquisa quantitativa e qualitativa composta de aplicação de questionário para os usuários do sistema (secretários escolares) e revisão de literatura. Constata-se que a face política do SIMADE oculta os mecanismos de poder, dominação e regulação emanados do Estado, incutindo nos secretários uma visão apenas operacional do sistema. Portanto, as interfaces configuram as práticas sistêmicas, utilitaristas e pragmáticas em prol dos princípios do Estado.

Published: January 2024

Esta reflexão tem como objetivo discutir utilizando uma base conceitual e por meio do filme Her, as formas como a vida contemporânea tem se comportado diante das tecnologias facilitadoras de relacionamentos afetivos. Usaremos perspectivas teóricas críticas do uso das tecnologias digitais para suprir e validar a compreensão das interações afetivas realizadas no ciberespaço. Os conceitos de sociação, filosofia da tecnologia, metrópole, amor líquido, entre outros, nos ajudam a pensar as relações afetivas contemporâneas tanto na perspectiva da subjetividade quanto mercantil da matéria. O argumento central desse artigo circunda em estarmos submetidos às tecnologias facilmente e como estas tecnologias podem moldar nosso cotidiano, nossas subjetividades, nossas vontades e desejos enquanto seres conscientes, na direção em abrir mão da afetividade material para se estar online.

Published: January 2024

Este trabalho tem o objetivo de apresentar as possibilidades que as tecnologias digitais possuem no âmbito do ensino-aprendizagem, sobretudo na disciplina de História, fazendo com que as aulas se tornem mais atraentes e motivadoras. Recorremos a uma metodologia de abordagem qualitativa através da técnica de revisão bibliográfica. Percebe-se que a figura feminina no âmbito historiográfico, em suma, foi invisibilizada. Sob esse viés, busca-se fazer o resgate da história das mulheres através dos aplicativos “Lessons In Herstory” e “Mulheres que Mudaram o Mundo”, contribuindo para a dinamização do ensino. Conclui-se que ainda existe muita disparidade entre a história ensinada com narrativas centradas na figura masculina e feminina, contudo, as tecnologias digitais são o caminho para tornar o ensino mais igualitário.

RESUMO:  Cenários recentes de crise em sistemas de abastecimento de água no Brasil reforçaram discussões sobre uma gestão mais eficiente dos recursos hídricos, abrangendo desde a captação ao uso final. Neste contexto, reduções das perdas nos sistemas de distribuição de água assumem vital importância com impacto direto na disponibilidade do recurso para usuários e geração de receita para as prestadoras de serviços. Este trabalho tem como objetivo uma prospecção tecnológica por soluções para detecção de vazamentos em redes de abastecimento de água. Por meio de pesquisas bibliográficas e patentárias, buscou-se levantar informações úteis para apresentação do panorama tecnológico tanto a nível nacional como internacional. Os dados levantados foram submetidos a análises quantitativas e qualitativas direcionadas à evolução temporal das publicações e depósitos, informações sobre depositantes ou autores e o tipo de solução tecnológica proposta. A pesquisa revelou que empresas nacionais e estrangeiras atuantes no mercado brasileiro não priorizam a proteção de suas tecnologias através de patentes. Os resultados com ferramentas de bases internacionais revelaram números substanciais e crescentes de depósitos de patentes com foco em tecnologias de medição realizados por grandes empresas sediadas no Japão. As publicações científicas relativas ao tema também demonstraram número substancial e crescente de artigos originados em grande parte por instituições da China e dos Estados Unidos, relativos às áreas de Engenharia e Ciência Ambiental.

Published: January 2024

RESUMO: Este trabalho tem o objetivo de propor uso do BIM para avaliar o desempenho de uma edificação. Para isso, foram criados dois modelos virtuais como objetos de estudo: real e de referência, seguindo parâmetros da NBR 15575 (ABNT, 2021). A finalidade desse procedimento foi possibilitar a manipulação direta de variáveis relacionadas aos objetos de estudo (modelos virtuais) para testar a hipótese da pesquisa. A modelagem foi realizada no Revit para ser simulado em um software de análise energética, sendo possível obter um desempenho satisfatório em quase todos os parâmetros, com exceção da redução da carga térmica no nível superior. Após esta etapa, foi argumentado os principais potenciais e adversidades da implementação do BIM na simulação energética, mostrando que apesar das limitações, há benefícios para destacar, como redução de esforço no fluxo de trabalho, diminuição no tempo gasto ao conectar o projeto e simulações, além da formação de um banco de dados que podem ser replicados em outros. Portanto, foi verificado que existem benefícios e limitações quanto a aplicação de modelagem virtual no processo de simulação. No entanto, seus benefícios prevalecem sobre os pontos negativos, especialmente quando abordado métodos tradicionais.
ABSTRACT: This work aims to propose the use of BIM to evaluate the performance of a building. For this, two virtual models were created as study objects: real and reference, following parameters of the NBR 15575 (ABNT, 2021). The purpose of this procedure was to enable direct manipulation of variables related to the study objects (virtual models) to test the research hypothesis. The modeling was performed in Revit to be simulated in an energy analysis software, being possible to obtain a satisfactory performance in almost all parameters, except for the reduction of the thermal load on the upper level. After this step, the main potentials and adversities of the implementation of BIM in energy simulation were discussed, showing that despite the limitations, there are benefits to highlight, such as reduced effort in the workflow, reduced time spent connecting the project and simulations, in addition to the formation of a database that can be replicated in other processes. Therefore, it was verified that there are benefits and limitations regarding the application of virtual modeling in the simulation process. However, its benefits outweigh the negative points, especially when compared to traditional methods.

Published: January 2024

RESUMO:  O crescimento urbano e as áreas de interesse ambiental que integram a malha viária estão cada vez mais suscetíveis a obras sem planejamento e infraestrutura. Nos últimos anos novos bairros surgem às margens de importantes vias de acesso no município e região. O objetivo desta pesquisa foi de analisar e comparar a infraestrutura adotada nos distintos bairros adjacentes à Rodovia Fernando Guilhon na cidade de Santarém-PA. Por meio de uma vasta revisão da literatura, consultando dados oficiais, artigos científicos e demais obras pertinentes, foi constituído um estudo especificando as principais questões que remetem as principais variáveis de infraestrutura e ambientais deste perímetro. Os principais resultados foram no sentido de denotar que a gestão pública não consegue acompanhar o crescimento urbano e os problemas gerados pela ausência de infraestrutura básica nos novos bairros, mesmo que estes sejam de uma certa forma privilegiados por uma boa localização em virtude de uma das principais vias de acesso da cidade. Esta pesquisa procurou motivar uma visão crítica do espaço urbano de Santarém relativo ao crescimento desordenado e pouco motivado à preservação do meio ambiente.

Published: January 2024

RESUMO:  A construção civil é um ramo de atividade com altos índices de acidentes de trabalho. Em relação as obras de pequeno porte, devido características de natureza provisória de alguns sistemas construtivos do canteiro, serviços de menores dimensões, curto prazo de execução e mão de obra temporária, estas apresentam as piores condições de saúde e segurança do trabalho na construção civil.  O presente artigo tem como objetivo avaliar e quantificar o cumprimento de normas regulamentadoras relacionadas à saúde e segurança dos trabalhadores em canteiros de obra de pequeno porte localizados na cidade de Goiânia (GO). O estudo se baseou na realização de vistorias de campo para a avaliação de rotinas de trabalho e aplicação de checklist a fim de identificar o grau de atendimento às exigências normativas. A partir dos dados coletados verificou-se que a maioria dos itens avaliados foi considerado “não conforme” em duas das obras avaliadas (com índices acima de 50%). Evidenciou-se a omissão da utilização de EPI´s em todos os casos assim como ausência de instalações hidrossanitárias básicas. Verifica-se que as obras de pequeno porte são construções de menor complexidade, porém, isso não significa que as mesmas devem receber menor rigor na aplicação das normativas e medidas de saúde e segurança do trabalho.
AVALIAÇÃO DO COMPORTAMENTO REOLÓGICO DAS MATRIZES CIMENTÍCIAS COM A ADIÇÃO DE NANOTUBOS DE CARBONO: UMA REVISÃO SISTEMÁTICA DA LITERATURA (RSL) – PARTE 1

Published: January 2024

RESUMO: A reologia do concreto afeta seu processo de mistura, manuseio, transporte, bombeamento, moldagem, adensamento, acabamento e qualidade da superfície após o endurecimento. A incorporação de nanomateriais nos compósitos cimentícios, como os nanotubos de carbono (NTC), pode influenciar os parâmetros do estado fresco. Contudo, ainda existem poucos trabalhos e uma grande variedade de resultados envolvendo parâmetros reológicos de matrizes cimentícias reforçadas com NTC. Este artigo visa levantar os principais parâmetros reológicos de matrizes cimentícias incorporadas com NTC através de uma revisão sistemática da literatura (Parte 1). Os dados bibliométricos foram apresentados na Parte 2. Compreender como os diferentes componentes e aditivos interagem e influenciam o comportamento reológico permite a criação de matrizes com propriedades avançadas. Muitos estudos mostraram que a tensão de escoamento e a viscosidade dos compósitos cimentícios com NTC mostraram uma tendência linear na primeira hora de hidratação. Ainda, o reforço com NTC aumentou gradativamente a tensão de escoamento e a viscosidade das pastas de cimento em parte das pesquisas. Isso se deve, principalmente, à alta superfície específica do NTC. Ao mesmo tempo, outros autores apontaram esse efeito ser reduzido ou até anulado através do uso de aditivos superplastificantes, como concretos autonivelantes, argamassas de alta aderência e materiais de reparo com características específicas.

Published: January 2024

This study analyses how financial support projects for universities led by the government have evolved and the implications of such projects. The research critically examines the progression of government-led financial support projects for universities that are integrated with local regions. It identifies the changing role of local governments in these projects, which now focus on structural adjustments and enhancing local university competitiveness. The study reveals that local governments have taken on diverse roles, including forming linkages, fostering cooperation, and making joint investments. However, their participation and policy involvement has been largely declarative, with actual demands and expectations for regional-university connections not fully met. Universities also lack clarity in their roles, leading to confusion and scattered investment efforts. A significant obstacle identified is the insufficient resources available to local governments, alongside the absence of a legal framework for independent budget management.

The goal of this work is to develop a system for monitoring forest fires in real time using an unmanned aerial vehicle (UAV). This study proposes a quadcopter-based forest fire monitoring system based on radio control from a ground station using a geolocation system. This approach ensures the effective use of UAVs both in automatic and manual modes with the help of onboard navigation equipment and controls. The hardware system is built using the ArduPilot controller and various sensors such as GPS, gyro compass, temperature sensor, distance sensor and digital cameras. Flight tests were carried out to assess the accuracy of the positioning system. The results show that the use of UAVs is an effective way to deal with a fire situation in addition to existing methods and technologies for solving operational problems of fire detection.

The paper considers a comparative analysis of the legal acts of providing workers with personal protective equipment of the European Union, the USA, Canada, the Russian Federation and other countries to justify the transition from the «list» approach to the issuance of personal protective equipment to the one used in international practice. Currently, the Republic of Kazakhstan uses a strictly regulated approach to the issuance of personal protective equipment based on established standards. The conditions of mass infection during the pandemic showed the ineffectiveness of the applied regulatory approach, without taking into account the nature of the risk. Therefore, in this direction there is a need for scientific substantiation of new approaches, taking into account the professional risk of the employee. During the review of international and domestic legal norms, key points of differences were identified, namely the use of a risk-based approach as the most modern and in line with modern trends and realities in ensuring the safe work of workers. Establishing a clear link with the results of occupational risk assessment will ensure the risk-oriented mechanisms for issuing personal protective equipment and training in safe work methods, which are modern measures of safe work in accordance with international legal practice. The article presents the results of scientific research obtained during the implementation of the scientific and technical program on the topic: «Risk-oriented organizational and economic mechanisms for ensuring safe work in the conditions of modern Kazakhstan» (IRN OR11865833-OT-21) within the framework of program-targeted funding of research of the Republican Research Institute for Labor Protection of the Ministry of Labor and Social Protection of the Republic of Kazakhstan.

Mineralization of various metals (Au, Ag, U, Ba, Mo, PB, Zn) and others are known in the Kokshetau Sredinny massif in the deposits of the Sharyk suite of the Riphean. Along with them, iron ore in the form of siderite ores is noted in a number of ore occurrences of the region. Siderites are confined to various deposits of the Sharyk Formation. The morphology of siderite ores varies from lenticular to bedded. Rich ores are noted at contact with intrusive formations. The genesis is sedimentary, contact-metamorphic, hypergene. The geology, genesis and prospects of siderite ores are substantiated, which can replenish the reserves of ferrous metals with the complex extraction of mineral raw materials in the region.

The processes and technologies of gas-flame surfacing of metal powders are considered, promising modern gas-thermal methods for creating a hardened surface layer of machine parts are established. The use of a specific surfacing method from the considered ones is due to the production conditions, the number, shape and size of the surfaced parts, the permissible share of the base metal in the surfaced, technical and economic indicators, and for restorative surfacing – the amount of wear. The choice of the type of deposited metal and, consequently, the grade of the filler material is made in accordance with the type of working loading of the deposited part. Therefore, when choosing the type of deposited metal, they focus on the prevailing type of wear. Based on the conducted studies of the gas-thermal method of applying wear-resistant coatings, a new design of the impeller of a centrifugal ground pump has been developed.

The logistics of a modern city attracts the attention of both scientists and authorities. In this regard, many articles are devoted to the study of transport policy and its impact on urban logistics. The observation data from the newsletter of RSE «Kazhydromet» on the composition of harmful substances in the atmosphere of the city were analyzed from the pollution of the air basin of the city of Almaty. Observations were carried out four times a day (1, 7, 13 and 19 hours local time). The list of controlled substances consists of six components: dust, carbon monoxide, nitrogen dioxide phenol and formaldehyde. The following table shows the limited values for impurities observed in Almaty. Meteorological parameters determining the distribution of suspended substances in the atmosphere were also observed, and the atmospheric pollution index was calculated. Logistics of the city and the factors influencing its change: the development of new technologies, economic factors, real environmental, social factors, external risks. The article lists the problems and changes in the logistics structure of the city that will occur in the near future. In the issue of regulating the logistics ecosystem of the city, it is necessary to take into account the interests of all stakeholders: manufacturers, carriers, logistics operators, consumers, passenger transport operators, municipal and regional authorities, etc. the latter should be ready for future changes and actively act, and not try to understand what happened after the facts.
