Effect of silica fume on strength of recycled aggregate concrete
Authors: Shahab Manzar , Bashar Noorul
Published: April 2024

The present study deals with investigating the effects of using coarse recycled concrete aggregates (RCA) on compression & split-tensile resilience of M25 grade concrete mixes. Five different mixes of modified recycle aggregate concrete (RAC) were designed and prepared considering replacement proportion of normal coarse aggregates as 0, 25, 50, 75, and 100 % with RCA. The specimens were prepared according to Indian standard codal provisions and experimentally tested for its mechanical characteristics in laboratory conditions. A steep degradation in compressive and tensile strength on increasing RCA proportion was observed, which may result due to improper bonding at interfacial region in RAC mixes. To overcome this strength deterioration, the effect of adding pozzolanic materials like silica fumes is also studied for making strength improvements. The silica fumes as admixture, in percentages of 4%, 8% and 12%, was added in RAC mixes for finding the optimum proportions. Overall, the study provides a sustainable solution for problematic concrete waste dumping while utilizing it in casting new concrete structures of significant strengths.

Published: April 2024

Com o intuito de fomentar a cultura do planejamento nas administrações municipais, o Tribunal de Contas do Estado de Mato Grosso (TCE-MT) instituiu o Programa de Apoio ao Gerenciamento do Planejamento Estratégico (GPE). Contudo, espera-se que a gestão pública, por meio de seus instrumentos de planejamento, alcance resultados positivos em relação à sustentabilidade local sem esquecer dos objetivos globais estabelecidos na Agenda 2030. Assim, o presente estudo teve como objetivo central analisar a (in) existência de alinhamento entre o Planejamento Estratégico de municípios de Mato Grosso em relação aos ODS’s propostos na Agenda 2030. Trata-se de pesquisa de natureza exploratória, descritiva e documental, baseada em informações internas, oriundas do Sistema de Gerenciamento do Planejamento Estratégico (GPE) do TCE-MT. Observou-se que a maioria dos indicadores têm foco nos ODS’s relacionados à dimensão Pessoas, abordando questões sociais como combate à pobreza e melhoria da qualidade de vida, enquanto à dimensão Parcerias recebe menos ênfase. Os principais desafios incluem o engajamento dos envolvidos, uma gestão eficiente e a escassez de metodologias de acompanhamento e monitoramento de indicadores. Destaca-se a necessidade de incluir os ODS nas Políticas Públicas de desenvolver parcerias para a implementação dos Objetivos de Desenvolvimento Sustentável (ODS) nos territórios.

Resource productivity in the economy of Ukrainian regions: trends and challenges
Authors: Yanovych Arseniy V.
Published: April 2024

The article addresses the resource productivity of the economy of Ukrainian regions and its impact on the total factor productivity of these regions. The main challenges of implementing the methodology for evaluating resource productivity offered by the European Union and the Organization for Economic Co-operation and Development in the Ukrainian context are outlined. In accordance with the mentioned methodology, the resource productivity in Ukraine across its regions in 2021 is assessed. The regions are categorized into four groups based on the examined indicator. A theoretical model of resource productivity is proposed. The key factors influencing resource productivity indicator are outlined. Based on this model, a hypothesis regarding the connection between the total factor productivity of regional economies and selected factors from the model is formulated. Through an empirical method, the following indicators are chosen for correlation-regression modeling: the natural logarithm of total factor productivity calculated using the Organization for Economic Co-operation and Development methodology; resource productivity; land plowing level calculated as the share of agricultural land in the total area of the region; resource production density calculated as the production of material resources per region area; the level of territory conservation calculated as the share of protected areas in the total area of the region. The selected indicators are tested for heteroscedasticity and multicollinearity, and a correlation matrix is created. Based on the correlation-regression analysis using the least squares method, the degree of influence of resource productivity on total factor productivity of regions is determined. Moreover, the hypothesis about the dependence of regional productivity on resource productivity and its production density is substantiated.

Authors: Sreekumar Paramesh
Published: April 2024

A preterm baby born at 35 weeks of gestation was noted to have severe limb deformities suggestive of arthrogryposis along with dysmorphic facies and developed seizures, renal dysfunction in addition to cholestasis. MRI brain showed corpus callosum agenesis. Although there are several isolated cases of arthrogryposis, the association with other congenital anomalies are rarely seen. The constellation of anomalies noted in this case along with renal tubular dysfunction and direct hyperbilirubinemia with normal GGT is suggestive of Arthrogryposis renal dysfunction Cholestasis (ARC) syndrome. It is a very rare autosomal recessive multisystem disorder resulting from mutations in the vacuolar protein sorting 33B (VPS33B) or VPS33B-interacting protein, and apical-basolateral polarity regulator (VIPAR) genes. This disorder is associated with a very poor prognosis with children seldom surviving beyond 1 year of age necessitating a detailed genetic evaluation to identify the various mutations and appropriate genetic counselling.
Internally Disclosed Sets of a Real Space
Authors: Sharafiddinov Rasulkhozha S.
Published: April 2024

There is no single set in a real space, for which an exact mathematical definition would not exist by the mathematical symmetry laws. We discuss a theory in which a real number axis is defined at the new level, namely, at the level of real space allowing one to formulate and prove the theorem on the basis of its internal disclosure. This new theory of a set makes it possible to introduce a notion of the full compactness of sets of a real space, confirming their availability in the defined symmetry of elements of a definitely symmetrical line.

First, we look at the most recent collection techniques, which include a variety of spectroscopic, chromatographic, and microscopic approaches used to identify and measure microplastics in water samples. We then investigate separation techniques designed to separate microplastics from diverse environmental matrices. This involves applying existing methods of separation based on density, such as centrifugation, flotation, and sedimentation, as well as more recent ones, like the use of microfluidic devices and materials for selective adsorption. Lastly, we look into removal methods aimed to reduce the buildup of microplastics in aquatic environments. These include enzymatic breakdown, coagulation/flocculation, and filtering, among other physical, chemical, and biological techniques.

Nearly one million light curves from the TESS Year 1 southern hemisphere extracted from Full Field Images with the DIAmante pipeline are processed through the AutoRegressive Planet Search statistical procedure. ARIMA models remove lingering autocorrelated noise, the Transit Comb Filter identifies the strongest periodic signal in the light curve, and a Random Forest machine-learning classifier is trained and applied to identify the best potential candidates. Classifier training sets are based on injections of planetary transit signals, eclipsing binaries, and other variable stars. The optimized classifier has a True Positive Rate of 92.5% and a False Positive Rate of 0.43% from the labeled training set. The result of this DIAmante TESS autoregressive planet search of the southern ecliptic hemisphere analysis is a list of 7377 potential exoplanet candidates. The classifier had a 64% recall rate for previously confirmed exoplanets and a 78% negative recall rate for known False Positives. The completeness map of the injected planetary signals shows high recall rates for planets with 8–30R
⊕ radii and periods 0.6–13 days and poor completeness for planets with radii <2R
⊕ or periods <1 day. The list has many False Alarms and False Positives that need to be culled with multifaceted vetting operations (Paper II).

We present the direct-imaging discovery of a substellar companion (a massive planet or low-mass brown dwarf) to the young, γ Doradus (γ Dor)-type variable star HIP 39017 (HD 65526). The companion’s SCExAO/CHARIS JHK (1.1–2.4 μm) spectrum and Keck/NIRC2

This discovery further reinforces the improved efficiency of targeted direct-imaging campaigns informed by long-baseline, precision stellar astrometry.

Recently, the Galactic magnetar SGR J1935+2154 has garnered attention due to its emission of an extremely luminous radio burst, reminiscent of fast radio bursts (FRBs). SGR J1935+2154 is one of the most active magnetars, displaying flaring events nearly every year, including outbursts as well as short and intermediate bursts. Here, we present our results on the properties of the persistent and bursting X-ray emission from SGR J1935+2154 during the initial weeks following its outburst on 2022 October 10. The source was observed with XMM-Newton and NuSTAR (quasi-)simultaneously during two epochs, separated by ∼5 days. The persistent emission spectrum is well described by an absorbed blackbody plus power-law model up to an energy of ∼25 keV. No significant changes were observed in the blackbody temperature (kT
BB ∼ 0.4 keV) and emitting radius (R
BB ∼ 1.9 km) between the two epochs. However, we observed a slight variation in the power-law parameters. Moreover, we detected X-ray pulsations in all the data sets and derived a spin-period derivative of

Additionally, we performed quasi-simultaneous radio observations using three 25–32 m class radio telescopes for a total of 92.5 hr to search for FRB-like radio bursts and pulsed emission. However, our analysis did not reveal any radio bursts or periodic emission.
Prospects of Identifying Hierarchical Triple Mergers for the Third-generation Ground-based Detectors
Authors: Gao Bo , Tang Shao-Peng , Yan Jingzhi , Fan Yi-Zhong
Published: April 2024

A hierarchical triple merger (HTM) constitutes a type of event in which two successive black hole (BH) mergers occur sequentially within the observational window of gravitational-wave (GW) detectors, which has an important role in testing general relativity and studying BH population. In this work, we conduct an analysis to determine the feasibility of identifying HTMs from a large GW event catalog using third-generation ground-based GW detectors. By comparing the Bhattacharyya coefficient that measures the overlap between the posterior distributions of the remnant and progenitor BH parameters, we find that the overlap between the event pair can serve as a preliminary filter, which balances between computational demand and the probability of false alarms. Following this initial, time-efficient, yet less accurate screening, a subset of potential HTM candidates will be retained. These candidates will subsequently be subjected to a more precise, albeit time-intensive, method of joint parameter estimation for verification. Ultimately, this process will enable us to robustly identify HTMs.

We report on the orbit of the binary system powering the most extreme ultraluminous X-ray pulsar known to date: NGC 5907 ULX-1 (hereafter ULX1). ULX1 has been the target of a substantial multi-instrument campaign, mainly in the X-ray band, but no clear counterparts are known in other bands. Although ULX1 is highly variable and pulsations can be transient (regardless of the source flux), the timing data collected so far allow us to investigate the orbit of this system. We find an orbital period

Digitalization and predictability in the BRICS countries: what can be learned from information about the dynamics of stock prices
Authors: Gurov Ilya
Published: April 2024

The study aims to identify the impact of digitalization on predictability in the BRICS countries’ stock markets. It is based on an analysis of the dynamics of stock markets volatility during the 1990-2023 period. The paper seeks to prove that the standard deviation of stock returns is determined by the volume of incoming new information, and higher volatility of returns indicates lower predictability. Digitalization may cause a reduction in uncertainty as it uses more data, improves their quality and develops data analysis methods. On the other hand, digitalization may lead to increased uncertainty due to the emergence and development of new industries, in which it is more difficult to predict cash flows in comparison with traditional industries because of increased complexity of supply chains and technologies. Based on quantitative analysis, it has been revealed that digitalization has led to a statistically significant decrease in the volatility of stock markets in the BRICS countries. In 2015-2023, relative to the period of the 1990s-2006, volatility in Russia decreased by 1 percentage point, in India by 0.4–0.5 percentage points, in China by 0.8 percentage points, in the UAE (Dubai) by 0.5-0.7 percentage points. Statistically insignificant decreases in volatility were observed in Brazil and South Africa. In the developed capital markets, the decrease in volatility between these two periods was also statistically insignificant, amounting to less than 0.1 percentage points. These findings may indicate that the processes of digitalization in the BRICS countries contributed to an accelerated increase in predictability thanks to an increase in the volume and quality of information and the emergence of new methods of analysis. At the same time, part of the decrease in volatility may be explained by further development and improved efficiency of capital markets. The joint influence of these effects on the complexity of forecasting turned out to be more significant than the impact of innovative technologies and new industries.
Allemagne. Revitalisation du partenariat social dans la « transformation » ?
Authors: Bosch Gerhard
Published: April 2024

Le modèle allemand de partenariat social s’est fissuré en raison de la dualisation du marché du travail, mais la « transformation » pourrait permettre sa revitalisation. L’évaluation des accords d’avenir dans la métallurgie et l’industrie électrique montre que la participation des représentants des salariés à la « transformation » n’est décisive que dans les secteurs où les syndicats et la codétermination sont forts. La « transformation » et la numérisation ont toutefois été à l’origine d’importantes réformes de la politique de négociation collective et des politiques publiques : elles ont fourni le « récit » de la nécessité d’un nouvel agenda politique avec une forte participation des partenaires sociaux.
L’ingénierie sociale : la prise en compte du facteur humain dans la cybercriminalité
Authors: Gross Denise
Published: April 2024

La révolution numérique a enrichi notre dictionnaire de nouveaux concepts. Nous avons entendu parler de piratage, de cybercriminalité, de cybersécurité, de hacker et de cybercriminel. Or, il y a quelques années, l’approche du facteur humain ne semblait pas prioritaire dans le cadre de l’analyse des problématiques liées à la sécurité informatique. Ces derniers temps, le terme « ingénierie sociale » sort enfin de sa coquille et se popularise pour expliquer un grand nombre de faits d’actualité.
Les métadonnées, source de toute information
Authors: Dupent Sébastien
Published: April 2024

Avant l’ère du numérique et au début de celle-ci, les métadonnées étaient les bribes d’information écrite, tamponnée ou imprimée sur différents supports tels que les photos, les enveloppes, les documents, etc. Lorsque les premiers photographes des années 1800 ont gravé des noms sur le cadre d’un daguerréotype, ils ont créé les premières métadonnées photographiques. Si l’on peut penser dans un premier temps que le traitement et l’analyse des métadonnées sont réservés aux experts informatiques (I), il paraît essentiel que ces dernières constituent un atout dans l’obtention d’informations clefs sur la provenance et l’authenticité d’un document (II).
