Published: July 2024

Совершенствование методики подсчета запасов метана имеет огромное значение для угольных предприятий, начиная с использования добываемого метана в котельной и заканчивая промышленной добычей газа. Недостаток энергетических ресурсов в Казахстане способствует повышению интереса к использованию нетрадиционных источников получения топливно-энергетического сырья. Одним из них, к тому же достаточно перспективным, является метан угольных пластов. Недостаточная изученность оценки ресурсов газа метана при отработке угольных месторождений приводит к большим потерям. Данное исследование позволит более точно вычислить ресурсы газа метана угольных пластов. В статье предлагается технология подсчета полезного компонента путем усредненного количества сорбционной емкости углей каждого из пластов.
Improving the methodology for calculating methane reserves is of great importance for coal enterprises, starting with the use of extracted methane in the boiler room and ending with industrial gas production. The lack of energy resources in Kazakhstan contributes to increasing interest in the use of non-traditional sources of fuel and energy raw materials. One of them, moreover, is quite promising, is coalbed methane. Insufficient knowledge of the assessment of methane gas resources during the development of coal deposits leads to both large losses. This study will make it possible to more accurately calculate the methane gas resources of coal seams. The article proposes a technology for calculating the useful component by averaging the amount of sorption capacity of the coals of each of the layers.

Over the past decades, due to the decrease in the quality of mineral raw materials from developed deposits, the share of gold extracted from refractory ores has increased, the effective processing of which requires the development of more complex and combined schemes that ensure the most complete extraction of gold. For the same purpose, in 2019, Navoi Mining and Metallurgical Combine (NMMC) successfully launched a workshop for roasting sorption cyanidation tailings during the processing of gold-bearing ores from the Kokpatas and Daugyztau deposits. At this stage, the NMMC specialists face the task of intensifying and optimizing the roasting process. This paper briefly presents the results of a detailed study of the effect of temperature on chemical transformations occurring during roasting of sorption cyanidation tails, carried out in order to identify the reasons that prevent the disclosure of gold particles during roasting and its encapsulation.

Published: July 2024

Given the growing significance of internet-based information flows, this research proposes a conceptual framework that integrates digital platforms to nowcast social phenomena, applied to the context of food security monitoring in the Global South. Building on the foundations of Digital Methods and online issue mapping, our research objective is to establish a multi-modal, multi-media model that monitors events from different perspectives to identify potential early warning signals arising from the data, ultimately informing policy actors and supporting early action. We apply three analytical processes: social listening, media monitoring and search interest analysis. Exploratory analysis on data from Zimbabwe point to the feasibility of the models applied to identify food security dimensions in text and search engine data. Further analysis is needed to interpret converging and diverging trends across the data streams, and their implications to food insecurity early warning.

Published: July 2024

RESUMO - Os resíduos sólidos podem ser fonte de metais pesados que afetam os solos. A capacidade de adsorção de cátions e ânions pelos solos depende das características físicas do meio, das concentrações dos elementos em solução, das cargas do complexo de troca e do pH. O objetivo desse trabalho foi analisar o comportamento químico de um Latossolo localizado em uma área adjacente ao Lixão da Estrutural, Distrito Federal, a partir da elevação do pH com a adição de pó de dolomito. Foram realizadas análises químicas de três conjuntos de amostras do solo, uma amostragem previa a adição do pó de dolomito e duas posteriores (após três e 12 meses). Para interpretação dos dados, foram realizadas análises individuais dos teores médios dos elementos, análise de correspondência com remoção do efeito do arco (DCA), análise de componentes principais (PCA) e teste estatístico de Mann-Whitney. Tais análises evidenciaram que a adição do pó de dolomito gerou aumento do pH e alteração dos teores dos elementos constituintes do solo e que as variações dos teores foram significativas ao longo de todas as campanhas de amostragem, indicando que o pH é um fator importante no controle de contaminação dos solos.

ABSTRACT - Solid waste can serve as a source of heavy metals that affect soils. The adsorption capacity of cations and anions by soils depends on the soil physical characteristics, the concentrations of elements in solution, the charges of the exchange complex, and the soil pH. The objective of this work was to analyze the chemical behavior of a Latosol located in an area adjacent to the Estrutural Landfill, Federal District - Brazil, from the increase of pH with the addition of dolomite powder. Chemical analyses were performed on three sets of soil samples, one sampling prior to the addition of the dolomite powder and two subsequent samplings (after three and 12 months). For data interpretation, individual analyses of the average element contents, detrended correspondence analysis (DCA), principal component analysis (PCA) and Mann-Whitney statistical test were conducted. These analyses revealed that the addition of dolomite powder increased the soil pH and altered the levels of its constituent elements significantly across all sampling campaigns, indicating pH as a crucial factor in controlling soil contamination.

Change Detection Analysis Using Drone-Based Photogrammetry for Long-Term Archaeological Site Erosion Monitoring
Authors: Pennanen Kelsey 
Published: July 2024

This paper presents a rapid, cost-effective, and non-specialist approach to long-term archaeological site monitoring that is repeatable and affordable. Advances in unmanned aerial vehicle (UAV)-based photogrammetry allow for the creation of multi-temporal three-dimensional (3D) models that permit accurate and in-depth analysis and quantification of landscape change through time. This paper presents a case study of aerial-based photogrammetric datasets using UAVs (i.e., drones) to conduct change detection analysis for monitoring continued erosion threatening an Indigenous buffalo jump in Alberta, Canada. The results demonstrate which areas of the site experienced the most significant change over a period of four years. By bridging gaps between traditional field survey and satellite-scale observations of impacts to large archaeological site complexes, UAV monitoring programs may become increasingly important as anthropogenic climate change continues to threaten heritage sites in Canada.

Authors: Krache Houssem , Leftaha Souad , Chougui Tarek 
Published: July 2024

Purpose. This study aims to determine the effect of company size, investment return ratio, own-retention ratio and underwriting results on both the solvency ratio based on technical provisions (YTP), and the solvency ratio based on net premiums (YNP) of 12 property-liability (P/L) insurance companies in Algeria during 2018–2021. This study uses the multiple regression analysis with the help of the SPSS program.
Results. The results of this study indicate that the underwriting results have a positive and significant effect on YTP of P/L insurance companies in Algeria during 2018–2021, while other variables do not affect YTP. This study also states that the own-retention ratio and underwriting results have a significant positive influence on YNP of P/L insurance companies in Algeria during 2018–2021, however the company size and investment return ratio do not affect YNP of these companies. The developed models explain only 32.4 % of the variation in dependent variable (YTP) and 61.7 % of the variation in dependent variable (YNP), implying that there are still other factors affecting solvency of P/L insurance companies in Algeria.
Scientific novelty. The scientific novelty of this research lies on knowing the factors affecting the solvency of insurance companies by focusing on Algeria, especially since the Algerian solvency system is still purely traditional and does not focus on the factors considered in this study.
Practical value. The findings will enable insurance companies in Algeria to optimally evaluate their solvency by focusing on the factors that have a significant effect on the solvency of insurance companies, thus ensuring the sustainability of these companies. Furthermore, the results of this study could be assistance to the insurance regulatory authority in Algeria to reconsider the rules of regulating solvency based on the factors that affect insurer’ solvency.
