Responsabilité Sociétale des Entreprises (RSE) du Secteur Minier
Authors: Reis Patrice , Garbaccio Grace Ladeira 
Published: September 2024

Il s'agit d'analyser la Responsabilité Sociétale des Entreprises (RSE) appliquée au secteur minier dans le contexte brésilien et français, sous un angle juridique, sans pour autant ne retenir que cette approche et de manière non exhaustive. On sait que l'aspect juridique, au regard de la notion de responsabilité elle-même (promue par le Droit de l'Environnement, le Droit des Sociétés, le Droit du Travail, etc.), est le premier élément d'interprétation de la RSE. D’un point de vue juridique, il existe des règles brésiliennes et aussi européennes, notamment françaises, dans le cadre de la Directive NFRD (Non-Financial Reporting Directive). Cependant, il est envisagé de présenter une perspective différente du terme responsabilité, en ce qui concerne l'engagement volontaire, l'auto-responsabilité des entreprises dans la mise en œuvre d'actions efficaces en faveur du développement social des parties prenantes. Cet article utilise la méthode de recherche déductive et exploratoire, basée sur l'analyse de références d'articles et d'études bibliographiques.

Published: September 2024

Addressing the health concern of fluoride ions contamination in water, that cause such deceases as dental and skeletal fluorosis, requires the development of effective adsorption materials for water treatment. Our research objective was to evaluate the adsorption properties and capacities of zeolite and bentonite, sourced from Ukrainian deposits, and their acid-activated forms in relation to fluoride ions and estimate fitting this data to various adsorption models. Characterization of natural and acid-activated zeolite and bentonite sorbents was performed through X-ray diffraction to determine the phase composition of these substances. Adsorption experiments were carried out at different initial fluoride ions concentrations (3, 5, 10 and 15 mg/l) and pH (3.7; 7.5). Acidification (changing pH from 7.5 to 3.7) increase adsorption capacity of natural zeolite and bentonite more than twice. It was found that natural zeolite removes fluoride ions at the level of 67 % at pH 3.7 and a high dosage of sorbent – 10 g/l and an initial concentration of fluoride ions – 5 mg/l, while its acid‑activated form was more effective - the removal of fluoride ions is 86 % at a lower dosage of sorbent – 1 g/l. Similarly, natural bentonite demonstrated a maximum removal efficiency of 45 % at pH 3.7 and a dosage of sorbent – 10 g/l, and its acid-activated form allowed for the removal of fluoride ions of about 83 % at a dosage of sorbent – 2 g/l at the same fluoride ions concentration. It is shown that the Vagelar-Langmuir (VL) isotherm model is the most accurate for describing the process of fluoride ions adsorption by acid-activated forms of natural sorbents, where the R² values are close to 0.999, indicating monolayer adsorption on homogeneous active centers. The obtained results indicate the greater efficiency of acid-activated forms of natural sorbents and the prospects of their use for the removal of fluoride ions from water.

Published: September 2024

The presence of mousy off-flavours in wine, attributed to the production of N-heterocycles by lactic acid bacteria or Brettanomyces bruxellensis, poses a significant challenge in the winemaking industry. This study is the first one to investigate the impact of co-cultures focusing on B. bruxellensis with two common wine microorganisms, Pediococcus parvulus and Saccharomyces cerevisiae on the formation of mousy compounds. The screening was conducted in a synthetic medium under controlled conditions. It reveals the nuanced effects of the microorganism combinations. Depending on the P. parvulus or S. cerevisiae strain co-inoculated with B. bruxellensis a synergistic effect is observed on the 2-acetyltetrahydropyridine (ATHP) production, while an inhibitory effect on 2-acetylpyrroline (APY) production by P. parvulus is highlighted when co-inoculated with B. bruxellensis. These findings shed light on the potential impact of the alcoholic fermentation yeast (S. cerevisiae) on the production of mousy off-flavours. Finally, a correlation between ATHP and 2-ethyltetrahydropyridine (ETHP) appears to be confirmed with a ratio of 1:10 between ETHP and ATHP produced in the N-heterocycles assay medium.

Published: September 2024

Background/Objectives: The aim of the narrative review was to identify information on the impact of technological interventions (such as telehealth and mobile health) on the health promotion of cardiac patients from diverse populations; Methods: Online databases of PubMed, and Cochrane Library were searched for articles in the English language regarding technological interventions for health promotion in cardiac patients. In addition, a methodological quality control process was conducted. Exclusion was based on first reading the abstract and then the full manuscript confirming content was not related to cardiac patients and technological interventions; Results: 11 studies were included in the review after quality control analysis. The sample size reported in these studies ranged from 12 to 1424 subjects. In 8 studies mobile phones, smartphones and apps were used as mHealth intervention with tracking and texting component; 2 studies used videoconferencing as a digital intervention program, while one study focused on using physical activity trackers; Conclusions: This review highlights the digital divide as individuals with limited eHealth literacy and lack of technological knowledge are not motivated or able participate in these interventions. Finding methods to overcome these barriers are important and can be solved to some extent by providing the technology and technical support.

Abstract
Production enhancement from tight carbonate reservoirs is essential to reach Kuwait's oil production target by 2030. This paper will demonstrate an integrated workflow that includes advanced reservoir characterization to optimize the stimulation design with enhanced zonal coverage in a heterogenous Jurassic reservoir, Middle Marrat of South Kuwait.
It is crucial to accurately select the candidates based on precise determination of the reservoir permeability contrast across the different layers. Representative fluid samples have been captured to map the asphaltene envelope. The injection logging survey was a key input
to determine the permeability profile and to evaluate the integrity of the patchy cement through temperature analysis. Pressure Transient Analysis (PTA) were essential to evaluate the significance of the depletion across the different areas of the field as well as to determine the total skin of the reservoir. The integration of these data in a structured workflow enhanced the stimulation design.
Based on the significant permeability contrast, Single-Phase Retarded Acid System (SPRAS) and Degradable Diverter System (DDS) were found to be essential to unlock the tighter layers. Five wells were stimulated utilizing the above workflow resulting in 7 folds of increase in the oil production versus 4 folds of increase before implementing this workflow. Another important observation is the sustainability of these wells for over 1 year with less frequency in asphaltene clean-out treatments. It can be observed that meticulous characterization, planning and execution for tight carbonate reservoirs is critical for a sustained production enhancement. This reservoir oil production has increased by 150% from existing wells with rigless intervention.
This paper demonstrates the economical development of deep tight carbonate reservoirs through fit-for-purpose workflows. The findings were utilized to update the full field development strategy.
