Authors: Parahita Aulia Hanesti , Tjahjono Mazda Eko Sri
Published: February 2025

This study uses company size as a moderating variable to examine how transfer pricing, sales growth, and leverage have an effect on tax avoidance. Manufacturing firms that were listed on the Indonesia Stock Exchange (BEI) in 2018 to 2022 make up the study's population. Fifty four firms were decided on as samples for this examine the usage of the purposive sampling approach. the use of SPSSv25 software program, moderated regression analysis (MRA) become used to analyse the statistics. The findings indicate that even as transfer pricing has no discernible impact on tax avoidance, sales growth and leverage have a positive effect. Furthermore, whilst company size can moderate the effect of leverage and sales growth on tax avoidance, it has no affect on the impact of transfer pricing.
Partai Politik dan Penurunan Ambang Batas Pencalonan dalam Pilkada (Studi Perolehan Suara Parpol pada Pemilu 2024 Propinsi Lampung)
Authors: Purwo nugroho Grace
Published: February 2025

Dalam regulasi pilkada lalu kepala daerah wajib memiliki  syarat   pengusung 20 % suara partai, dan ini menjadikan  partai politik menjadi kartel dalam mengusung calon. Hasil pemilu 2024 tidak ada satu partaipun yang mencapai 20 %,  diketahui tertinggi PDI Perjuangan 16,72 % dan terendah PAN 7,23 %, sehingga tidak ada parpol secara nasional  yang dapat mengusung calonnya  sendiri kecuali di beberapa daerah partai tertentu melebihi perolehan 20 % suara.  Putusan MK No. 60/PUU-XXII/2024  menurunkan jumlah syarat pencalonan untuk level propinsi dan kabupaten  yakni maksimal 10  % dan minimal 6,5 % suara partai tergantung jumlah penduduk  dan partai banyak memiliki peluang sendiri.   Permasalahan yang muncul apakah partai memiliki kesiapan memanfaatkan  peluang tersebut,  apakah dengan demikian partai dapat melakukan optimaliasi fungsi rekrutmen internal untuk calon dalam pilkada ?  penelitian   bertujuan menganalisis basis hasil pemilihan pemilu nasional 2024 dan  implikasi putusan MK terhadap posisi partai yang semakin  kuat dalam pencalonan kepala daerah di masa yang akan datang, dengan demikian agenda pelembagaan  dan fungsi partai semakin baik.  Penelitian ini juga dapat dimanfaatkan untuk melakukan review terhadap kondisi partai di daerah secara kontekstual. Partai secara umum memiliki fungsi rekruitmen politik, sosialisasai, komunikasi dan pengurai konflik yang pada akhirnya semua fungsi untuk menunjang ideologi dan tujuan sebuah partai politik.  Penulisan jurnal ini menggunakan metode  tinjauan pustaka untuk mengumpulkan data yang berupa riset sebelumnya, data publik dan informasi yang kredibel dan terlegitimasi. Dalam hasil penelitian ditemukan korelasi  penurunan  ambang batas pencalonan oleh MK telah memberikan peluang partai mempersiapkan diri dan memungkinkan pelaksanaan fungsi partai yang lebih optimal minimal pada saat pilkada yang akan datang. Partai-partai harus berbenah diri dan menadi leader dalam isu-isu sosial, melakukan konsolidasi dan menyusun proyeksi politik pada tingkat lokal sehingga dalam jangka panjang mampu membentuk partai yang kuat dan optimal menjalankan fungsi. Berdasarkan hasil review penelitian sebelumnya dan temuan data, banyak  partai belum secara mandiri untuk mendesain untuk pencalonan kepala daerah, terbukti pada pilkada 2024 tidak banyak partai yang melakukan upaya mencalonkan sendiri kader atau pihak lain karena memang ambang batas partai memenuhi syarat.

Authors: Hedy Rahmad
Published: February 2025

Poligami secara mendalam adalah perkawinan yang dilakukan laki-laki kepada perempuan lebih dari seorang, temtunya dalam praktek pelaksanaanya terdapat pro dan kontra terhadap poligami. Demi kemaslahatan umum diperlukan adanya alasan-alasan terhadap perkawinan poligami. Misalnya, kemandulan seorang wanita yang kehilangan daya fisik atau mental akan banyak menyeret terjadinya perceraian dari pada poligami. Penelitian ini bertujuan untuk mengetahui dan menganalisis regulasi yang poligami masih belum mencerminkan nilai- nilai keadilan Islam, Untuk mengatahui dan menganalisis kelemahan-kelemahan regulasi Poligami dan Untuk menganalisis konsep ideal dalam merekontruksi tata kelola perkawinan poligami agar tidak dianggap tabu dan risih dimata keluarga dan lingkungan. Penelitian ini merupakan penelitian hukum normatif yang digunakan untuk meneliti fungsi suatu norma yang meletak undang-undang sebagai instrumen yang mengatur dan mengendalikan masyarakat. Pendekatan yang digunakan dalam penelitian ini menggunakan paradigma kontruktivisme yaitu suatu paradigma yang memandang realitas kehidupan sosial bukanlah realitas yang natural, tetapi berbentuk dari hasil kontruksi). Teori hukum yang digunakan sebagai analisis yaitu teori keadilan Islam sebagai grand theory, teori sistem hukum sebagai middle theory, dan teori hukum progresif sebagai apply theory. Hasil dari penelitian ini ialah Regulasi poligami yang diatur dalam undang-undang nomor 1 tahun 1974 sebagaimana telah diubah dengan undang-undang nomor 16 tahun 2019 tentang perkawinan masih belum mencerminkan nilai- nilai keadilan islam karena terdapat beberapa pasal dalam Undang-Undang Perkawinan Nomor 1 Tahun 1974 yang berkaitan dengan poligami khusunya syarat untuk mendapatkan persetujuan Isteri kurang relevan dengan perkembangan zaman, Kelemahan-kelemahan regulasi poligami yang diatur dalam undang undang no. 1 tahun 1974 sebagaimana telah diubah dengan undang-undang nomor 16 tahun 2019 tentang perkawinan dan didalam alqur’an serta hadist saat ini adalah aturan poligami hanya mencakup keadilan materiil saja, dan Konsep ideal dalam merekontruksi tata kelola perkawinan poligami agar tidak dianggap tabu dan risih dimata keluarga dan lingkungan adalah Menambahkan persetujuan anak dan menambahkan norma hukum baru pada berupa 1 huruf dalam Pasal 5 ayat (1) Undang-Undang Nomor 1 Tahun 1974 Tentang Perkawinan yaitu huruf d. yang berbunyi “bahwa jaminan suami akan berlaku adil terhadap isteri-isteri dan anak-anak dituangkan dalam perjanjian perkawinan yang dilakukan sebelum melangsungkan perkawinan poligami.

Advance Consent for Interventional Radiology Procedures
Authors: Shankarghatta Rohan , Garnett Alexandra
Published: February 2025

Background
Advance consent is crucial for patients undergoing Interventional radiology (IR) procedures with potential serious harm. Two previous audits at our hospital revealed issues with obtaining consent before the day of the procedure, leading to the implementation of a consent clinic. Subsequently, a new electronic patient record (EPR) system was introduced. This third audit cycle assessed whether these changes improved the advance consent rates for vascular IR procedures.
Method
We retrospectively reviewed 53 patients who underwent vascular IR procedures in January 2023, noting whether each procedure was inpatient or outpatient, urgent or elective, and the procedure type. These results were compared with previous cycles to evaluate adherence to consent standards.
Results
Among the 53 patients, there was an even split between inpatient and outpatient procedures, as well as between urgent and elective procedures. 27 patients underwent lower limb angiogram/angioplasty, 19 had fistula work, and 7 underwent other procedures. 77% of patients consented in advance or had the consent process initiated beforehand.
Conclusion
An improvement in advance consent rates was noted compared to previous cycles (14% → 63% → 77%) following the implementation of consent clinics and the new EPR system. However, 33% of patients, primarily those undergoing fistula work, still consented on the day of the procedure. This audit highlights the benefit of the new EPR system and the need to continue consent clinics, emphasizing the importance of advance consent, especially for fistula procedures.

Published: February 2025

There been increasing interest in polymetallic nodule mining within the Clarion-Clipperton Zone (CCZ). Polymetallic nodule mining within NORI-D will release a sediment plume within the water column and a previous mining collector test within the Nauru Ocean Resources Inc. (NORI-D) contract area released surface pollution from mining tailings. The mid-water plume, as well as accidental surface pollution, indicate that polymetallic nodule mining could impact surface plankton. Although the ichthyoplankton within the eastern tropical Pacific have been well-studied, recent data from within polymetallic nodule mining licence areas is lacking. Environmental Expedition C5e conducted an environmental baseline assessment of both pelagic and benthic fauna within the NORI-D region of the CCZ, which included the opportunistic collection of ichthyoplankton.

Ichthyoplankton were collected within NORI-D from November–December 2021 using two plankton nets and a Remotely Operated Vehicle (ROV). Here, we present a checklist of ichthyoplankton within the NORI-D licence area during this winter campaign. Eighteen samples were collected and identified through morphology, with a limited number identified through genetic sequencing. Specimens were from five orders, including Argentiniformes, Stomiiformes, Myctophiformes, Beloniformes and Scombriformes. This checklist will aid contractors and scientists conducting work within the CCZ to examine how wastewater discharge from polymetallic nodule mining could impact fish reproduction and ichthyoplankton survival.
Les Bangladais·es en « séjour précaire », un hors-champ social
Authors: Meister Sofia
Published: February 2025

La notion de « hors-champ social » permet d’articuler les dimensions institutionnelle, spatiale, sensible et épistémique de l’invisibilité sociale et de le saisir comme processus dans lequel sont pris les ressortissant·es du Bangladesh en « séjour précaire » résidant en Île-de-France. En s’appuyant à la fois sur la notion bourdieusienne d’espace social et sur celle d’espace public comme scène sociale d’apparition, il s’agit de montrer que la production institutionnelle du « séjour précaire » induit des pratiques et des stratégies d’invisibilisation ainsi que des circulations et des espaces cachés des regards. Cette invisibilisation sociale et spatiale est redoublée par des perceptions socialisées, en particulier l’attention dans l’espace public francilien, régie dans une situation postcoloniale par les rapports sociaux de classe et de race.
De la survisibilité/invisibilité sociale à la colère politique
Authors: Vermeren Pauline
Published: February 2025

En partant des formes d’invisibilisation des personnes perçues comme noires dans les récits de Ralph Ellison et Richard Wright, cet article propose de réfléchir au lien entre invisibilité, survisibilité et reconnaissance sociale. Cela permet d’introduire le lien entre invisibilité sociale et invisibilisation épistémique face à la proposition d’une phénoménologie critique et décoloniale reconfigurant le champ politique du sensible traversé par l’affect de la colère. Ce « jeu » tragique entre survisibilité ontologique et invisibilité sociale contient un partage du sensible caractérisant une histoire politique globale de la race et du racisme. Il implique des processus d’invisibilisation épistémique, à savoir l’effacement d’existences, par leurs productions, leurs traces et leurs mémoires, ou encore leur occultation comme acteurs dans des contextes où leurs rôles ont été socialement, politiquement et historiquement déterminants – résistance, indépendance, émancipation. Ce travail contribue à interroger la production d’un savoir philosophique et sa responsabilité quant au lien entre invisibilité épistémique et invisibilité sociale, au regard de la disparition des corps noirs des espaces de pouvoir et de savoir en les reléguant à ses marges dans une « zone de non-être », selon l’expression de Fanon, et sans histoire propre. Cet article défend l’idée qu’il ne peut y avoir d’analyses d’une condition d’existence sans faire de lien avec les conditions politiques de production de ces connaissances.
Dans l’arène de la (non) verbalisation
Authors: Eyebibi Elieth
Published: February 2025

Les pratiques d’éveil essentiel constituent un outil de socialisation de l’enfant. Elles donnent lieu à une économie sociale de la (non)verbalisation et de la signification qui infuse largement la construction de l’enfant comme être social au sein de la communauté. Réverbérées à travers l’outil complexe du conte, trois pratiques d’éveil recommandées par la santé publique et opérées par l’institution scolaire – le parler, les mimiques et les comptines –, se retrouvent au cœur d’enjeux et luttes symboliques faisant de la socialisation de l’enfant une arène au sein de laquelle les nouveaux protestantismes prennent la parole pour bousculer les traditions ancestrales. À partir d’une enquête de terrain au sein de deux communautés agraire Aizo et lacustre Tofin du Bénin méridional, selon la méthode de l’Enquête collective et rapide d’identification des groupes stratégiques (ECRIS), l’article propose une micro sociologie des pratiques d’éveil dans la socialisation de l’enfant. L’article montre comment la collusion entre discours de la santé publique, de l’éducation scolaire et discours réformateur religieux, bouleverse l’ordre social traditionnel autour de la parole comme enjeu dans la socialisation de l’enfant. Il soutient que l’économie des pratiques d’éveil de l’enfant se dévoile dans une arène sociale de la (non)verbalisation, au sein de laquelle l’affrontement des acteurs autour d’enjeux symboliques s’inscrit dans une confrontation entre les catégories du moderne et du traditionnel.
Les sorties culturelles des Français·es
Authors: Glevarec Hervé , Combes Clément , Nowak Raphaël , Cibois Philippe
Published: February 2025

Le champ des sorties culturelles représente un domaine de pratiques qui a connu, depuis les années 1970, un mouvement d’extension continu. Certaines sorties comme la sortie au cinéma sont très communes tandis que d’autres, comme la sortie à l’opéra ou concert de rap, sont plus circonscrites et différenciées. S’appuyant sur les données quantitatives de l’enquête Pratiques culturelles en France de 2018 et sur une enquête qualitative réalisée en 2021-2022 par entretiens, cet article se propose, d’une part, de montrer la structuration culturelle et sociologique des sorties culturelles à partir d’une analyse multivariée, et, d’autre part, d’en explorer les motivations à partir de trois notions que sont la « compétence », le « concernement » et « l’attachement ».
Energy-Efficient SWIPT-Aided NOMA With Spatial Modulation for Green Communication in Beyond 5G/6G Networks
Authors: Srikamu C. , Jayabharathy R. , Sujanth Narayan K. G. , Karthikeyan S.
Published: February 2025

This chapter presents a Simultaneous Wireless Information and Power Transfer (SWIPT) base Cooperative Non-Orthogonal Multiple Access (CNOMA) system aided by Spatial Modulation (SM), designed by energy-efficient or “green” communication in beyond 5G (B5G) and 6G applications. The proposed system leverages NOMA to enhance spectral efficiency by allowing multiple users to share the same frequency and time resources, differentiated through power domain multiplexing. SWIPT is incorporated to enable near users to harvest energy from the received RF signals, which relay information to far users in a cooperative NOMA system. Spatial modulation reduces hardware complexity by activating a single antenna for data transmission, significantly enhancing energy efficiency while maintaining high data rates. This SM SWIPT NOMA framework addresses the challenges of power-constrained and spectrum-limited scenarios, providing a low-power, high-performance solution ideal for green communications. The system finds applications in smart cities, massive machine-type communication (mMTC) and vehicular networks where energy efficiency, coverage extension and user fairness are critical. Simulation results demonstrate the system's superior energy efficiency, spectral efficiency and performance gains compared to conventional techniques, making it a viable solution for sustainable communication in B5G and 6G networks. At a transmit power of 20 dBm, energy harvested in SM SWIPT NOMA is 135.12 joules and that of SM SWIPT OMA is 67.56 joules.

Published: February 2025

In the globalized educational background, quality management and accreditation in higher education have become paramount to maintaining academic standards, fostering institutional accountability, and promoting a culture of continuous improvement. Globally, frameworks like ISO 9001, guidelines from organizations such as the International Network for Quality Assurance Agencies in Higher Education (INQAAHE), and the European Association for Quality Assurance in Higher Education (ENQA) shape quality management practices. However, this paper examines recent global trends in quality management and accreditation in higher education. As institutions world-wide face increasing demands for accountability, student satisfaction, and international standards, understanding these trends has become essential for policy-makers and academic leaders. Using data from leading accreditation bodies and case studies from various regions, it also analyses the impact of international accreditation, digital transformation, and the shift toward continuous improvement in educational quality management.

Empowering Futures: Understanding Pregnancy Planning amongst Young Women in Rural Part of Central India
Authors: Rajashekhar M. , Kolhe Rutuja , Dhatrak Amey
Published: February 2025

Introduction:

Unplanned pregnancies result in pre-mature births and other adverse pregnancy outcomes. The concept of unplanned pregnancy helps in understanding pregnancy planning, fertility and the unmet need for contraception.

Materials and Methods:

Descriptive study in young women either recently pregnant or had delivered/aborted in the last year was conducted. London Measure for Unplanned Pregnancy (LMUP) questionnaire was employed. Information about family planning and folic acid (FA) intake was assessed. Data were analysed using Microsoft Excel.

Results:

About 53.7% of pregnancies were intended and nearly 35% were unintended. Less than half of the participants were aware of FA and only 7.5% were aware of FA intake in the pre-pregnancy and pregnancy period. No one got knowledge regarding FA from Accredited Social Health Activists or auxiliary nurse midwives. Only 53.7% were using contraceptives, in which condoms and Cu T were most used.

Conclusion:

Still many pregnancies are unintended, and the sense of planning for pregnancy is missing in young women. Most young women were aware of contraceptives but not using them and most women were not aware at all about FA tablet intake.
Promoting patient safety in critically ill patients: nursing interventions in surveillance and prevention of ocular injuries
Authors: Raposo Anabela Carvalho , Durao Maria Candida , Pinto Maria do Rosário , Henriques Helga Rafael , Teixeira Joana Ferreira
Published: February 2025

Corneal surface injuries occur frequently (59.4%) in critically ill patients, and the average time for their appearance is 8 days. Such injuries are primarily related to dry eye, which increases the risk of exposure injury in patients admitted to intensive care units. This can result in a severe ulcer or perforation that results in partial to total loss of vision, decreasing the quality of the patient's life. This is a sensitive nursing care area requiring further investigation. Thus, this review aims to analyse nursing interventions that aim to prevent ocular surface injuries. An integrative literature review was carried out from May to August 2023 in the Medline, CINAHL, Scopus, Web of Science, and PubMed databases using the Whittemore and Knafl methodology. Inclusion and exclusion criteria were subsequently applied to assess the results. After verifying result eligibility, seven documents were identified for data extraction and analysis. The results suggest the importance of recognizing risk factors for ocular injuries in critically ill patients, surveillance as a nursing competency, adequate ocular hygiene and effective lubrication, and managing environmental conditions to prevent corneal injuries. Implementing surveillance and intervention protocols for critically ill patients at risk of corneal injuries requires specialized training for critical care nurses. Specifically, environmental management, including temperature and humidity control, is highlighted as an area that merits further research.

The aim of the present study was to evaluate the cardiotonic activity and to determine the probable mechanisms of action of aqueous  extracts of the leaves (EAFBAE) and roots (EARBAE) of Balanites aegyptiaca on isolated toad heart. The cardiotonic activity of the extracts  and their mechanisms of action were determined using the Langerdhorff device. In this study, digoxin (0.5 mg/mL) was used as the  standard, while adrenaline (10-2 mg/mL) acetylcholine (10-6 mg/mL) and propranolol (10-6 mg/mL), amlodipine (10-6 mg/mL) and atropine (0.1 mg/kg) were used to determine the probable mechanisms of action of the extracts. The study of the cardiotonic activity  showed that EAFBAE (3mg/mL) and EARBAE (2mg/mL) significantly (< 0.05) induced positive inotropic and chronotropic effects on the  isolated toad heart as compared to digoxin. In the presence of propranolol (β-adrenergic antagonist) and amlodipine (calcium channel  blocker), EAFBAE (3mg/mL) and EARBAE (2mg/mL) significantly decreased the cardiac contractility (heart rate, force of contraction and  cardiac output), as compared to adrenaline. The results of this study suggest that the extracts tested have beneficial and interesting  effects in stimulating cardiac activity via the adrenergic pathway and calcium channels.

La prise en charge efficiente de l’anémie chez les insuffisants rénaux chroniques (hémodialysés) est devenue un problème majeur de  santé publique. L’objectif de cette étude était d’évaluer le contenu en hémoglobine des réticulocytes en vue de détecter précocement  l’anémie chez ces patients et de préciser l’origine de cette anémie. L’étude a porté sur 60 patients insuffisants rénaux chroniques (IRCs)  en hémodialyse. Elle a consisté à l’évaluation des paramètres hématologiques grâce à la technologie de cytométrie en flux des produits et systèmes Sysmex. Les résultats ont révélé une anémie chez ces patients IRCs à travers de faibles taux en hémoglobine des  érythrocytes corrélés positivement avec des valeurs normales du taux d’hémoglobine des réticulocytes (RET-He) et de Delta-He. La  corrélation positive entre ces paramètres et le taux d’hémoglobine évoquerait l’origine inflammatoire de l’anémie observée chez ces  IRCs. Le RET-He et le Delta-He pourraient donc représentés des biomarqueurs essentiels pour une meilleure surveillance de l’anémie  chez les patients IRCs.

Les eaux de mares sont les premières sources d’irrigation des sites maraîchers dans la ville de N’Djaména. Elles constituent donc des  menaces permanentes pour la santé aussi bien humaine qu’animale. Ce travail vise à évaluer la variation saisonnière de la contamination  des eaux de mares de la ville de N’Djaména en bactéries pathogènes de genre Salmonella ainsi que les paramètres  physico-chimique en lien avec cette variation. Des prélèvements des échantillons des eaux de mares ont été réalisés dans 16 (Seize) sites  couvrant 7 arrondissements (1, 3, 5, 7, 8, 9 et 10) de la ville de N’Djaména sur une période de 12 mois (Juillet 2021-Juin 2022). L’analyse microbiologique a été faite selon la norme ISO 6579:2007. Les souches de Salmonella ont été isolées suivant la méthode standard de  microbiologie et confirmées par la galerie Api 20 E. Des analyses physico-chimiques telles que le pH, la conductivité et la Température ont  été effectuées avec un multi paramètre de marque EXTECH (EC500). Les résultats ont montré que le taux de contamination annuelle  des eaux est compris entre 31% et 71% ; le taux se situait entre 36,38% et 58,33% selon les arrondissements avec une fréquence élevée en  saison sèche 62,8% suivie d’une baisse en saison de pluies égale à 37,13%. La conductivité de ces eaux variait entre 924 µs/cm et 3669  µs/cm ; le pH se situait entre 7,45 et 7,90 ; La température la plus faible était 28, 33°C et la plus haute 32,03°C. La présence des  salmonelles dans ces eaux pourrait être à l’origine de la contamination humaine.

La sous-préfecture d’Hiré est une zone à forte activité minière qui exerce une pression sur l’environnement et les ressources en eau. En  effet, ces activités impactent les ressources en eau en perturbant leur quantité et leur qualité. Cette étude a été effectuée dans le but  d’établir une carte de vulnérabilité intrinsèque à la pollution des eaux-souterraines de la zone minière d’Hiré, afin d’apprécier les  endroits où les eaux souterraines peuvent être sensibles aux infiltrations de polluants. La méthode DRASTIC appliquée dans cette étude,  prend en compte des paramètres intrinsèques de la nappe (niveau statique, recharge, géologie, nature du sol, topographie, zone vadose  et conductivité hydraulique). Elle a permis de mettre en évidence sur une carte, trois plages de vulnérabilité. Une vulnérabilité très faible  prenant en compte 1% de la superficie de la zone d’étude, une vulnérabilité faible prenant en compte 93% de la surface et une  vulnérabilité moyenne de 6% de la surface occupée. Aussi, les faibles taux de nitrate issus des forages coïncident-ils avec les classes de  vulnérabilité faible, et permettent de valider la carte de vulnérabilité réalisée. La Sous-préfecture d’Hiré, est donc une zone où la  vulnérabilité à la pollution due aux infiltrations est faible de façon générale.

En aval des stations d'épuration, les eaux usées traitées contiennent divers éléments traces métalliques (ETM) qui s'accumulent dans les  écosystèmes naturels, atteignant des niveaux toxiques et causant d'importants impacts écologiques. Le but de cette étude est d’évaluer  les concentrations en ETM dans les sites exposés à l’épandage de ces eaux, dans la région de Béni Mellal (Maroc), en utilisant le ver  Eisenia fetida comme bioindicateur. Pour ce faire, des échantillons du ver de terre ont été prélevés en 2022 selon un pas bimestriel sur trois sites. Les concentrations en ETM (Cd, Zn, Cu, Cr, Pb, Al, Fe et Mn) dans les tissus d’E. fetida ont été déterminées par spectrométrie  d’émission atomique couplée à un plasma induit (ICP). Les résultats montrent que la bioaccumulation des ETM est fonction du site, du  mois de prélèvement ainsi que de l’élément métallique en question. Le calcul de l'indice de pollution métallique (IPM), a montré que les  trois sites sont pollués. Les vers provenant du site (KH) présentent les concentrations les plus élevées en Cd et en Cu, tandis que ceux du  site (BM) accumulent principalement le Cu et le Cr. Pour le Zn, il est fortement bioaccumulé par les spécimens du site (AZ). Globalement,  une similarité est observée entre les sites (BM) et (KH).

Tamarindus indica L. is a multi-purpose wild fruit tree that is highly exploited in Burkina Faso, and its habitats are being degraded. This  study aimsed to determine the demographic and health characteristics of Tamarindus indica conserved in different habitats in western  Burkina Faso. So three types of land management were identified: agroforestry parklands (PA), parts of forests subjected to wildfire (FAF)  and parts of forests that have not been subjected to wildfire (FSF). Some 146 square plots measuring 2,500 m2 each were set up,  including 65 in PA, 46 in FAF and 37 in FSF. An exhaustive inventory of trees was carried out and the dendrometric parameters recorded.  The health of each individual was assessed. The results reveal a species richness of 82 species composed of 65 genera and 33 families.  The highest density values were found in the FAF (55.33±4.27 N/ha); mean diameter in the PA (30.22±16.46 cm); mean number of T. indica  regenerations (PA=1.73±0.67 seedlings/ha; FAF=3.30±1.02 seedlings/ha; FSF=7.14±1.14 seedlings/ha). These values varied  significantly (p˂0.05) with the land management method. Tamarind has low regeneration and it regenerates more by seedling (77.44%)  than by shoot (22.56%). It is cut down and burnt, and the tree infestation rate is higher in agroforestry parklands (11.84%). It would  therefore be essential to determine the conditions for conserving its seeds and encourage the practice of assisted regeneration to  safeguard the species.

A Study of Different Antenna Models on the Performance of UAV-Based LoRa Communication Network Using Taguchi and ANOVA Methods
Authors: Mohd Ghazali Mohamad Hazwan , Teoh Kelvin , Wan Rahiman
Published: February 2025

In a UAV-based LoRa communication network, one critical aspect that requires careful consideration is the weight applied to the UAV, which can be affected by the choice of antenna and the size of the power source utilized to operate the LoRa device. Therefore, in this study, the effects of different antenna models, transmitting powers (TP), and surrounding temperatures on the performance of LoRa are investigated under varying conditions. The other contributions of the paper include investigating the optimum LoRa configuration under different test scenarios and the correlation between TP and power consumption. Based on the Taguchi and ANOVA analysis, the optimum LoRa configuration in terms of packet delivery rate (PDR) for a 1 km direct line-of-sight scenario is TP = 15 dBm, antenna model = 5 dBi antenna, and surrounding temperature = 34°C. With the optimum setting, the power consumption was reduced to approximately 168.4 mW, and 3789 times more data transmission can be achieved compared to the default parameter. Therefore, a smaller power source can prolong the UAV flight time.

Maize (Zea mays L.), or corn, is the world’s leading cereal crop and ranks third in importance after rice and wheat. It is a primary food source for humans and livestock and a raw material in various industries. To reduce dependence on corn imports, Malaysia has initiated large-scale local cultivation. However, the maize industry faces challenges from waterlogging and water scarcity due to the tropical climate, which causes droughts and floods, impacting maize production. This study aims to improve crop water requirement (CWR) estimations for maize using CROPWAT, considering growth stages and soil variability, and validate irrigation management strategies. Based on 30 years of climatic data from MetMalaysia, evapotranspiration (ETc) was estimated using CROPWAT V8. Experimental plots with four irrigation water application (IWA) treatments were used to validate ETc: T1 (50% ETc), T2 (75% ETc), T3 (100% ETc), and T4 (125% ETc). Crop growth parameters were assessed at four growth stages: plant height, stem diameter, shoot fresh weight, and kernel moisture. Results showed T4 (451.07 mm/season) had the highest growth rate and met all hybrid corn growth standards set by the Department of Agriculture, Ministry of Agricultural and Food Security (MAFS). In contrast, T3 (100% ETc) was insufficient for sweet corn, failing to meet several standards. Thus, T4 (125% ETc) proved the most effective IWA practice, particularly for areas within a 30 km radius of the Subang weather station.

Published: February 2025

This study explores the potential of using calcium hydroxide (Ca(OH)₂) derived from Carbide Lime Waste (CLW) as a high-volume cement replacement (40%–70% by volume) in mortar. The mortar was subjected to accelerated carbon dioxide (CO₂) curing to enhance carbonation capture while maintaining the desired strength, promoting more sustainable construction practices. The optimum high-volume mortar was further analysed to examine its long-term properties under various postconditioning treatments, including water, wet gunny, and air curing, in terms of calcium carbonate (CaCO3) formation and late-age strength. The physical properties, such as water absorption and mechanical properties, including compressive, flexural, and splitting tensile strengths, were evaluated. CO2 capture performance was assessed through carbonation depth testing, and microstructural analysis was performed using Thermogravimetric analysis (TGA) and X-ray diffraction (XRD). Results showed that CLW70 exhibited the best mix design, achieving 100% carbonation depth and 70% CaCO3 formation within 7 days of accelerated CO2 curing. Compressive strength increased from 2.62 MPa on day 1 to 17.01 MPa on day 7. XRD analysis indicated that air curing was the most effective postconditioning treatment, resulting in the highest CaCO3 peaks. Accelerated CO2 curing also reduced water absorption, and mechanical strength improved with curing age, demonstrating that the CaCO3 formed during the carbonation process densified the CLW mortar after 7 days of curing.

Arduino microcontroller and ADXL accelerometer are commonly paired devices, often considered for creating inexpensive vibration analysers. Many researchers have proven that both pairing devices have good performance in vibration measurement and have the potential for commercialisation. This study evaluates the feasibility of vibration measurement and monitoring using an Arduino microcontroller with an inexpensive accelerometer in detecting anomalies during water pump operation. A dedicated Arduino Mega and an ADXL345 accelerometer were attached to a water pump motor to facilitate continuous monitoring of vibrations. The vibration measurement was set at a sampling rate of 530 Hz. Vibration data in RMS value was sent to the cloud storage for monitoring. Raw data captured during normal and abnormal conditions were collected at the site when anomalies were detected for further analysis. The results showed that the abnormal conditions could be clearly differentiated from normal conditions using the Fast Fourier Transform method and spectrogram analysis. In summary, this study confirms that integrating the Arduino Microcontroller with the ADXL accelerometer effectively detects irregularities in the operating conditions of the water pump.

Prioritizing health is crucial, yet it remains unfulfilled and requires increased attention. To address this issue, an automated artificial intelligence (AI) application that monitors postures and actions during exercise would be highly beneficial. In the proposed article, we offer a remote AI powered yoga trainer. This trainer incorporates OpenCV for live image capture and processing, which helps in identifying the key poses. Advanced AI techniques, such as deep learning, have proven beneficial in monitoring applications. In the proposed article, we proposed three AI yoga trainer models using deep neural network (DNN), convolutional neural network (CNN), and multilayer perceptron (MLP) models. We evaluated the proposed model’s performance on a publicly available dataset sourced from Kaggle, where we focused on obtaining yoga pose images, as well as their captions. Data processing, which includes data cleaning and augmentation, is performed to ensure the diversity of the dataset. A carefully curated set of yoga poses, such as chair, cobra, and shoulder stand, helps to provide beginner-friendly and health-beneficial practices remotely, thereby preventing the neglect of physical health.
