Published: December 2024

Résumé La présente étude a permis d’évaluer d’une part la provenance de l’eau consommée par les acteurs de l’enseignement et d’autre part les conditions hygiéniques des latrines dans les écoles officielles de la commune de Kasuku dans la ville de Kindu. Les enquêtes de latrines ont été réalisées auprès de différents enquêtés soit 60 élèves et 10 administratifs sélectionnés aléatoirement dans 16 écoles.Ainsi, 81% des élèves ont reconnu que l’eau consommée dans leurs écoles provient soit d’une source aménagée soit de la Régidéso. A 70% des latrines scolaires ne sont pas utilisées par les élèves, le manque d’entretien ou de nettoyage était la raison majeure.Cette situation est en défaveur de l’environnement propice à la santé et constitue donc un réel problème de santé publique qui doit faire l’objet d’une attention particulière de la part de tous les animateurs de l’enseignement et de la santé, attention sans laquelle le rendement scolaire risque d’en pâtir.Abstact The present study made it possible to evaluate on the one hand the source of the water consumed by the actors of teaching and on the other hand the hygienic conditions of the latrines in the official schools of the commune of Kasuku in the town of Kindu.  The investigations of latrines were carried out near various inquired either 60 pupils and 10 administrative selected by chance in 16 schools. Thus, 81% of the pupils recognized that the water consumed in their schools comes either from an arranged source or of Régidéso.  To 70% of the school latrines are not used by the pupils, the lack of maintenance or of cleaning was the imperative reason. This situation is in discredit of the environment favourable with health and thus constitutes a real problem of public health which must be the subject of a detailed attention on behalf of all the organizers of teaching and health, attention without which the school output is likely to suffer from it.

Published: December 2024

Les résultats obtenus ont montré que la population de la cité de Pont Kwango est constituée par des personnes qui portent des profils divers. Les habitants de cette cité recourent les plus souvent aux latrines de fortunes, à la brousse et aux rivières pour déféquer avec une forte utilisation des latrines de fortunes. Le manque des latrines aménagées suivant les normes à la cité du Pont Kwango affecte la rivière Kwango. Quatre types des maladies hydriques surgissent observées fréquemment dans la cité de Pont Kwango dont : la fièvre typhoïde, la diarrhée puis la contamination par les vers intestinaux et le paludisme. Les valeurs moyennes de certains paramètres physiques (turbidité et conductivité) et chimiques (Demande biologique et chimique en oxygène, matière en suspension, phosphore et azote) des eaux de la rivière Kwango ont montré que cette dernière est contaminée par divers composés organiques et inorganiques suite aux activités anthropiques notamment la matière fécale qui contribuent à dégrader la qualité de ces eaux. La densité des coliformes fécaux notamment d’Escherichia coli dans l’eau de la rivière Kwango confirme la contamination des eaux de cette rivière par la matière fécale humaine. Il se dégage donc que la partie de la rivière Kwango qui traverse la cité de Pont Kwango est caractérisée non seulement par une contamination organique et minérale mais aussi par un haut degré de contamination microbienne par le truchement de la matière fécale ; ce qui restreint les divers usages de cette eau et expose également la population. Il est donc à craindre que cette rivière devienne davantage contaminée avec l’évolution de la démographie dans cette cité si des mesures appropriées ne sont pas prises en compte.

Published: December 2024

La coexistence entre agriculteurs autochtones et éleveurs allochtones dans la commune de Savè, comme dans de nombreuses régions du monde, est souvent marquée par des tensions et des conflits liés à l'usage des terres et des ressources naturelles. Cette recherche analyse les Modes locaux de résolutions des conflits entre agriculteurs autochtones et éleveurs allochtones dans la Commune de Savè. La démarche méthodologique utilisée est mixte. Elle a pris en compte de façon raisonnée 110 individus tous répartis dans 10 localités de la Commune de Savè. De l’analyse des résultats, il ressort que les conflits entre agriculteurs autochtones et éleveurs allochtones sont dus à l’insuffisance et au non-respect des couloirs de passage ; à l’utilisation des produits chimiques ; à la méconnaissance des textes agropastoraux ; aux changements climatiques et aux pressions démographiques. En outre, le non-respect des engagements des éleveurs après la constatation des faits et en règlement des dégâts expliquent aussi la récurrence et la persistance des conflits dans la commune. Pour résoudre ces conflits, les parties prenantes optent plus pour le règlement à l’amiable. En examinant ces dynamiques locales, l'article offre des insights précieux pour la compréhension des conflits interculturels et la promotion de la paix dans d'autres contextes similaires.

Published: December 2024

This research evaluates the integration of hybrid electric military vehicle technology and how it impacts defense budget optimization. A cross-sectional survey design with a quantitative approach was employed to collect and analyze data. The survey was conducted among 30 respondents representing various age groups, educational backgrounds, and work experiences. Through a series of validity and reliability tests, as well as analysis of descriptive responses, it was found that interest in the concept of electric hybrid vehicles among respondents was very high. The results showed significant validity (sig. <0.05) for all survey items, with fairly high reliability (>0.600). The analysis included descriptive statistics to provide an overview of respondents' characteristics and attitudes, as well as inferential statistics to evaluate the relationship between attitudes towards technology and support for its implementation. The majority of respondents showed high interest in the electric hybrid vehicle concept, supported by their perception of environmental benefits and operational efficiency. More interestingly, the authors found solid support for the integration of this technology in military infrastructure, with the belief that investment in the development of hybrid-electric military vehicles could optimize defense budgets. While challenges in adapting infrastructure and training personnel are acknowledged, support for implementation remains high. This research confirms that hybrid electric military vehicle technology has great potential as a solution to increase defense efficiency and readiness, while ensuring more optimal use of resources in the defense budget

La baisse de la fertilité des sols agricoles causée  par l’emploi inadéquat des engrais minéraux représente une contrainte fondamentale à la production agricole. L’utilisation des biofertilisants constitue des méthodes durables de fertilisation qui augmentent le rendement des cultures tout en protégeant  l’environnement.L’objectif  de cette étude est  d’évaluer l’effet de dose  des fientes de poulets sur la croissance et le rendement du gombo (Abelmoschus esculentus L. Moench) cultivé à Bongor. Pour cela, la longueur de la tige principale et le diamètre au collet ont été mesurés et les vitesses de croissance associées ont été calculées. Le nombre des feuilles, des fleurs et des fruits, le nombre de graines par fruit, le nombre de graines  par loge ont été relevés. Le poids des fruits frais, la matière sèche des fruits, la matière fraiche de la biomasse aérienne, la matière sèche de la biomasse aérienne ont été notés  et le rendement a été estimé. Des résultats ont montré qu’ en dehors du rendement en fruit, les plants ayant reçu 40 g de fientes de poulet ont présenté des meilleures performances pour tous les paramètres évalués. Ces résultats confirment l’importance de la fiente de poulets dans la fertilisation des sols et permettent de dire à l’état actuel des connaissances, que la fiente de poulets pourrait être une alternative dans la lutte contre l’appauvrissement des sols et la restauration des terres dégradées mais également un élément en faveur de la politique de sauvegarde environnementale.
Modeling The Dimensional Stability Of Linen Fabrics
Authors: RAVONISON Elie Rijatiana , RAOELISON Barimino , RAKOTOSAONA Rijalalaina
Published: December 2024

This article relates the dimensional stability of fabrics made from linen. More precisely in this work we find the shrinkage’s evolution and shrinkage of linen fabrics after washing and drying. To do this, several articles made of linen are studied in order to have a better appreciation of the behavior of linen fabrics. Knowing that the reference values for the study of dimensional stability are the width defined in centimeters (cm), the initial dimension and the dimension after washing the sample in centimeters and the difference illustrated in percentage. This percentage which reflects the elongation or shrinkage of the fabric is shown by equations which represent the mathematical models of the dimensional stability of the linen fabric. During this study, two types of sample groups are considered: dyed linen fabrics and white linen fabrics. When mathematically modeling dimensional stability, the accuracy of the models are defined by the respective relative and absolute errors.
Modeling The Tensile Strength Of A Linen Fabric: Case Of A Dyed Woven Fabric
Authors: RAVONISON Elie Rijatiana , RAOELISON Barimino , RAKOTOSAONA Rijalalaina
Published: December 2024

This article relates the behavior through mathematical models of the tensile strength of a fabric composed of linen. During this work, 3 types of dyed woven fabric composed of linen are sampled. With these 3 types we obtained 63 samples taken and studied, and from these samples we were able to derive the tensile strength behavior of the fabric. The characteristics observed during the experiments which can influence the tensile strength of the fabric are: the width and weight of the fabric, the density of the warp and weft yarns of the fabric, the tensile strength and the kilometer resistance of the yarns, and the actual metric number of the yarns. A mathematical model is developed for each characteristic considered. The mathematical models are presented with their accuracies illustrated by relative and absolute errors.

Published: December 2024

The PPC cements and their ultra-fine grainy matrix are widely recognized as ideal engineering materials due to their unique cementitious features owing to dispense exceptional placing, adhering, setting, and enduring abilities. The underlying key parameters deterministic to all these distinctive potentialities are quality of the pozzolana, type of the crystallite phases & their average size distributions, and the particular identities of the chemical moieties/functional groups. The precise assessments of each of them instrumentally in variable technology manufactured yet publicly desirable ready-to-use dry PPC cements always provide the trustworthy means of granting not only their entire qualities but also unequal aptitudes for workability, compressive strength, stability of the C–S–H (I) & C–S–H (II) gluing gels, water penetration & permeability resilience, sustainability of the concrete structures, hair cracking preventions, etc. In this study, we employed XRD and FTIR spectroscopic techniques, and characterized all the founding chemical phases needful to assure the quality of the four topmost PPC cements branded across the commercial markets of Nepal. The critical spectral interpretations of the: (a) diffractograms reveal alite, belite, & silicates as predominant; portlandite, & calcite as premier; fly ash, gypsum, aragonite, & vaterite as subsidiary; and silica, arsenate, & organic traces as ultra-trace crystallite phases; and (b) IR spectrograms verify all the chemical fragments and functional groups of each of these phases such as Ca-O (fly ash); Si-O-Si (silica, α-quartz); S-O of SO42− (gypsum (CaSO4)); CO32− of CaCO3 polymorphs; As-O of AsO43- (calcium arsenates); Si-O of alite (Ca3SiO5) & belite (Ca2SiO4); SiO44- & SiO42- of silicate tetrahedra & polymerized orthosilica (Si2O7)6-; O-H & H-O-H of hydrous portlandite & crystal water of the calcite and gypsum; C-H of organic traces; and O-H of granularly adsorbed/absorbed molecular water (H2O) & H-bound OH (H---OH) segments. We strongly believe that this research article illuminates the standard measures of assessing real quality of the PPC cements and of standardizing their Nepal Standard (NS) codes.

Stealth technology is one of the technologies being developed to eliminate RADAR traces from the enemy. The spectrum used in this technology is in the microwave range (8-12 GHz). RAM (Radar Absorbing Material) is one of the techniques that can be used in the design of stealth technology. One material that has the potential to be used as RAM is activated charcoal as a dielectric material. In the manufacture of activated charcoal, a chemical activation method is used with an activator in the form of 5 M HCl to obtain good porosity properties in charcoal. Modification of active charcoal was also carried out using mechanical milling method with time variations of 50, 100, 150, and 200 minutes which were then characterized using X-Ray Diffraction (XRD), Scanning Electron Microscopy - Energy Dispersive Spectroscopy (SEM-EDS), and Vector Network Analyzer (VNA). Mechanical milling is proven to be able to change the shape of the charcoal structure from amorphous to semicrystalline with the crystalline phase formed in the form of C60-fullerene. Activated charcoal samples with a time variation of 100 minutes have the best absorbing ability with absorption reaching 78.22% and a reflection loss value of -25.96 dB at a frequency of 9.69 GHz with a frequency bandwidth of 3.68 GHz.Keywords—stealth technology; rice husk activated charcoal; mechanical milling; microwave absorber.

This study explores novel valorization pathways for Canna indica biomass, extending beyond traditional ethanol production. Through pyrolysis, we transformed non-conventional plant parts such as stems and leaves into charcoal and biochar, aligning with a circular economy approach. Despite having lower calorific value compared to traditional coal, our biochar offers significant environmental benefits, including carbon sequestration. Furthermore, Canna indica briquettes are easier to handle and store compared to conventional charcoal. Moreover, we innovated by utilizing distillation residues as a binder for briquette production, enhancing their physical properties. This multidisciplinary approach paves the way for sustainable energy production and environmentally friendly agriculture.

Published: December 2024

Preeclampsia is a frequent complication of pregnancy. It is a multi-organ sickness that stays one of the predominant causes of maternal morbidity and mortality. Additionally, preeclampsia leads to many problems that can appear in the fetus or newborn. Preeclampsia occurs in about 1 in 20 pregnant women. This review focuses on the prediction of preeclampsia in women, the use of a number of biomarkers, in particular, a factor combining the use of soluble FMS-like tyrosinokinase-1 (sFlt-1) and placental growth factor (PlGF). A low value of the sFlt-1/PlGF ratio guidelines the incidence of preeclampsia within 4 weeks of the test result, and its high value predicts the incidence of preeclampsia within 1 week. The assessment additionally highlights different factors, such as pregnancy-associated plasma protein A, placental protein 13, disintegrin and metalloprotease 12, b-human chorionic gonadotropin, inhibin-A, soluble endoglin, nitric oxide, and growth differentiation factor 15. Biomarker checking out gives dependable and affordable screening techniques for early detection, prognosis, and monitoring of preeclampsia. Early diagnosis in groups of women at high risk for preeclampsia permits for speedy intervention, stopping the undesirable outcomes of preeclampsia. However, in addition research is wished to validate and optimize the use of biomarkers for extra correct prediction and diagnosis. This article objectives to evaluation the function of biomarkers, such as the sFlt1/PlGF ratio, in the prognosis and management of preeclampsia.

Published: December 2024

This study investigates the potential of Canna indica rhizome as a promising substrate for biogas production through anaerobic co-digestion with cow manure. Experimental results demonstrate that a 50:50 mixture of Canna indica rhizome and cow manure optimizes biogas yield, achieving a methane content of 64.48%. This synergistic effect is attributed to the complementary chemical composition of the substrates.To provide an initial estimate of biogas production, an existing mathematical model was adapted without significant modifications. Despite its original design for different substrates, the model exhibited satisfactory performance in predicting biogas production trends, highlighting the general applicability of its underlying principles to this specific co-digestion system.

Published: December 2024

Este caso clínico detalla a un paciente con VIH avanzado que desarrolló un sarcoma de Kaposi (SK) diseminado, afectando piel, mucosas, pulmón, hígado y otros órganos. El objetivo fue documentar la complejidad clínica y las complicaciones fatales de esta neoplasia asociada a inmunosupresión severa. El paciente presentó lesiones cutáneas y viscerales extensas, con TAC revelando infiltrados pulmonares y nódulos en varios órganos, confirmados por biopsias como SK con proliferación vascular anómala. La discusión destaca que la inmunosupresión avanzada, exacerbada por una reciente infección por COVID-19, facilitó la rápida progresión del SK. Este caso subraya la necesidad de una intervención temprana con terapia antirretroviral y manejo adecuado del SK. En conclusión, el manejo tardío del VIH y del SK limita significativamente las opciones terapéuticas y generalmente conduce a un desenlace fatal, resaltando la importancia de estrategias diagnósticas y terapéuticas oportunas para prevenir la evolución agresiva en pacientes inmunosuprimidos.

Authors: Farhoomand Aksoy Darya , Akbulut Simay Ezgi , Büyük İlker
Published: December 2024

The Late Embryogenesis Abundant (LEA) gene family is considered vital for plant's ability to survive freezing and desiccation, affecting important developmental and growth processes. These proteins possess notable hydrophilicity and thermal stability, which are essential for preserving cell membrane integrity, forming molecular barriers, aiding in ionic binding, and mitigating oxidative damage during extended periods of exposure to abiotic stress conditions. Although LEA proteins have been extensively studied in numerous plant species, this study represents the initial comprehensive exploration and characterization of LEA proteins in Phaseolus vulgaris L. In this context, the biochemical/physicochemical properties of the LEA family at both the gene and protein level have been deeply characterized and defined using various bioinformatics tools. Through comprehensive bioinformatics analyzes, we identified 80 LEA genes in common bean and phylogenetically categorized their proteins into eight major groups. Investigating gene duplications, we uncovered 28 events, including 24 segmental and 4 tandem duplications, significantly influencing the evolutionary trajectory of this gene family. In silico micro-RNA (miRNA) target analyzes revealed that 21 PvLEA genes were targeted by various miRNAs, with miRN2588 and miR164 being the most prevalent. PvLEA-63 emerged as the most highly expressed gene across tissues, followed by PvLEA-27, PvLEA-35, PvLEA-41, PvLEA-49 and PvLEA-52 genes, demonstrating their ubiquitous expression patterns. Moreover, using publicly available RNAseq data, a comparative expression study of PvLEA genes was carried out, and expression alterations in PvLEA-02, -08, -20, -21, -40, -42, -50 and -51 genes were detected under both salt and drought stress conditions. These results constitute a substantial resource for future researchers interested in unravelling the functional intricacies of PvLEA genes.

Mathematical models (theory) have been developed, surfaces of the lowest values of the criteria
for drillability and explosibility of ores and rocks of curvilinear-anisotropic rock massifs of ore deposits, and a method for zoning quarry and mine fields by categories of drillability and explosibility. The purpose of the research is to reduce the cost of drilling and blasting by 20% or more, based on the development of projects for the production of drilling and blasting operations, in accordance with their actual properties of geological bodies that make up mineral deposits.
The application of the proposed technical solutions will make it possible to achieve high-quality crushing with the lowest possible costs for blasting, as well as to ensure resource saving, energy saving during blasting, to ensure the stability of the slopes of worked-out spaces, etc. The proposed method has been tested in the quarries of the Republic of Kazakhstan. There are no analogues of the proposed method.
A NEW APPROACH TO SOLVING THE PROBLEMS OF INCREASING THE EFFICIENCY OF GEOTHERMAL FIELD DEVELOPMENT
Authors: Mendebaev T.N.
Published: December 2024

The initial prerequisites for the effective development of geothermal deposits have been developed.
Geological - reliable information about the geological structure of thermal water deposits, compositions, physical and mechanical properties of rocks in the “water-rock” system.
Technical - means of well construction, design features and technological capabilities corresponding to the conditions of the mining environment, ensuring the production of highly informative geological material in the form of a core, maintaining the stability of the walls of wells from collapse and shedding. A series of diamond drill bits with a hydrojet effect of rock destruction, corresponding to the conditions of opening hot springs, have been developed and tested in practice for drilling wells. A scheme of a circulation system for the opening and development of geothermal deposits consisting
of a vertically injection and an obliquely ascending well connected by a smooth bend of an intermediate shaft is proposed. The ideological novelty of the scheme, which differs from all known schemes for the development of geothermal deposits in the world, provides for the possibility of creating conditions for the manifestation of the internal energy of the earth’s interior and the thermal horizon, aimed at improving the efficiency of the development of geothermal deposits. The structural features of the scheme are that a vertical injection well lined with a filter column in the section of the thermal horizon is made with ledges, where shock waves of increased and decreased pressure are generated when water is supplied, by dividing the water flow into a central core and lateral components. As a result, the thermal horizon is affected by alternating hydraulic impulses, an increase in rock permeability and an acceleration of water inflow into the well. At the same time, by linking the borehole system with an intermediate trunk, and laying an ascending well with an obliquely cased filter column, the volume coverage of the thermal horizon is provided, increasing the uninterrupted operation period, where the circulation channel from the lower ledge to the entrance to the tank with smoothly bending joints is made with one diameter. This eliminates local pressure losses. By grinding the wall of the intermediate shaft with rock hardening, water leaks and pressure losses along the length of the circulation channel are eliminated. The significance of the circulation scheme - the extraction of hot water is carried out by forced self-discharge, without attracting energy from outside.

Published: December 2024

The removal of the toxic dye malachite green (MG) from aqueous effluents using organically modified clay (OC) was investigated in a batch system. The OC was synthesized by intercalating the cationic surfactant hexadecyltrimethylammonium bromide into Algerian montmorillonite. The study explored the effects of initial dye concentration, temperature, pH, and contact time on dye adsorption. The OC demonstrated high dye removal efficiency (99%) at an initial dye concentration of 100 mg L−1, pH 6, and 20°C. The adsorption capacity was found to be independent of pH but increased with temperature, with maximum adsorption capacities of 350, 380, and 398 mg·g⁻¹ at 20°C, 30°C, and 40°C, respectively. The adsorption process was characterized by rapid initial uptake followed by a slower rate until equilibrium was reached, with a maximum uptake of 49.45 mg·g⁻¹. The experimental data were best described by the Langmuir adsorption model, indicating monolayer adsorption on homogeneous sites. Kinetic studies revealed that the sorption rate followed a pseudo-second-order model, with a high correlation (R² = 0.999), suggesting a chemisorptive nature of the interaction. Thermodynamic analysis indicated that the process was spontaneous and endothermic, with positive enthalpy and negative Gibbs free energy values. Overall, the OC proved to be an effective and environmentally friendly adsorbent for the removal of MG dye from wastewater.

Published: December 2024

To highlight the role of lactic acid bacteria in meat safeguarding, bacteria from various types of local red meats (Annaba- Algeria) preserved under various conditions were isolated and characterized. Isolation was limited to lactobacilli and some types of spoilage and pathogenic bacteria. The characterization of the isolated strains was done by means of physiological and biochemical identification tests. Various methods were considered to characterize the antimicrobial activities of the 29 isolated lactobacilli strains from 19 samples. The results revealed that the isolated lactobacilli strains produce and excrete in the culture medium substances showing important inhibiting activities towards Gram positive and Gram negative bacteria. These activities are due to various molecules, but varied according to the lactobacilli and the considered bacteria. Inhibition by lactic acid and H2O2 was observed for the Gram+ and the Gram-, except for Pseudomonas. Bacteriocin inhibition was especially observed for the Gram+, while among the Gram-, only Salmonella was inhibited. Bacteriocin activity towards S. aureus was confirmed for eight strains of lactobacilli, resulting from standard thermostable extracellular proteins for six of them. This study shows that the isolated lactobacilli present important antibacterial activities, which suggested that they can be used for a better conservation of fresh meat, in order to preserve its microbiological quality; since they are already widely used in Europe for the fermentation of meat products like dry sausage.
