(University of Eloued جامعة الوادي, 2024) DERDAKH, Saleh.GHANEM, Adel. TALBI, Moussa.TERKI ,Abdeldjabbar.; GHANEM, Adel; TALBI, Moussa; TERKI ,Abdeldjabbar.
With the escalating interest in clean and sustainable energy, solar panels have emerged as a leading source of renewable energy worldwide. As nations and enterprises increasingly turn to solar power to fulfill their energy requirements, addressing the challenges and malfunctions encountered by solar panels has become imperative for sustaining this technology.
In this significant project, our objective is to deploy a monitoring and fault-detection device for PV panels. The system will utilize a microcontroller to govern the DC/DC boost converter through the development of a PCB circuit. Programmed to extract pertinent data from the photovoltaic panel, the device will transmit this data to an intelligent system for assessing the panel's operational status. Leveraging machine learning algorithms forms the technical cornerstone of this project, augmenting the device's capability to discern and pinpoint Avec l‘intérêt croissant pour les énergies propres et durables, les panneaux solaires sont devenus l‘une des principales sources d‘énergie renouvelable dans le monde. Alors que les pays et les entreprises se tournent de plus en plus vers l‘énergie solaire pour répondre à leurs besoins énergétiques, il est devenu impératif de relever les défis et les dysfonctionnements rencontrés par les panneaux solaires pour pérenniser cette technologie.

Current Controlled of Three-Phase Grid-Connected solar PV Systems
(University of Eloued جامعة الوادي, 2025) CHAIB, Ouiem .; HAMMADI, Manel.
This study presents the simulation and analysis of a Grid-Connected photovoltaic system. The model provides a detailed representation of key components, including the solar array, boost converter, and Grid-Connected inverter. An optimized DC/DC converter control strategy has been implemented to maximize energy extraction, ensuring efficient Maximum Power Point Tracking (MPPT). The Grid-Connected inverter facilitates seamless energy transfer by maintaining a stable DC-link voltage. Modeling and control strategies are developed and validated using MATLAB/Simulink, with simulation results demonstrating the system’s control performance and dynamic behavior under varying conditions.حخ اُ لٔ زْ انذساست يحاكاة حٔحهيم ظَاو ك شٓ ضٔ ئٕي يخصم بانشبكت انك شٓبائيت. يقذّو ان رًُٕج ح ثًي ا لً حفصيهياا نه كً إَث

فعالية الري بالمياه الجوفية الساخنة في الخصائص الفيزيولوجية والفيتوكيميائية لنبات النعناع المائي والنعناع الجبلي ونبات البوقريبة

This study aims to evaluate the effectiveness of irrigation using hot
groundwater on a range of physiological and phytochemical characteristics in three
common medicinal plants: water mint (Mentha aquatica), mountain mint (Mentha
longifolia), and Zygophyllum cornutum, under the harsh environmental conditions
typical of arid regions such as the Wadi Souf area in southern Algeria.
Two irrigation treatments (hot groundwater (50°C) and cooled hot groundwater
(30°C) were applied to the studied plants. Various physiological and biochemical
indicators were then measured, including chlorophyll content, water content,
cellular water capacity, yield, total polyphenols, flavonoids, tannins, and
antioxidant activity (using DPPH and FRAP assays).
The results revealed significant differences between the treatments. Irrigation with
cooled hot groundwater showed a positive effect on most of the indicators
compared to direct hot groundwater irrigation, highlighting the role of thermal
adjustment in improving plant response and mitigating stress impacts. Conversely,
a decline in certain indicators was observed under direct hot water irrigation,
indicating a potentially harmful thermal effect in the absence of cooling.
Statistical analyses (ANOVA followed by the Least Significant Difference (LSD)
test) confirmed statistically significant differences and revealed variability in
responses among the three plant species, demonstrating differences in biochemical
and physiological tolerance.
The study concludes that using hot groundwater after cooling may represent a
sustainable alternative for agricultural irrigation in southern Algeria, helping to
maintain the quality of plant production, especially in light of current climate
challenges and limited surface water resources.
Caractérisation de certains paramètres d'adaptation anatomiques de certaines plantes spontanées du Sahara septentrional est-algérien.
(جامعة الوادي university of eloued, 2025) CHAOUCHE ICHRAK; HATATRA SARA
Cette étude vise à analyser les mécanismes d’adaptation chez 12 espèces de
plantes désertiques spontanées, appartenant à quatre familles botaniques : les
Poaceae, les Zygophyllaceae, les Chenopodiaceae et les Cyperaceae. Les
analyses anatomiques des tiges et des feuilles révèlent une diversité de stratégies
permettant à ces plantes de survivre dans des conditions environnementales
extrêmes (chaleur, sécheresse, salinité, et pauvreté du sol).
Pour identifier ces mécanismes, des coupes anatomiques ont été réalisées : une
coupe transversale de la tige et une coupe longitudinale de la feuille.
Les principaux traits d’adaptation observés sont les suivants :
Épiderme : épais, recouvert d’une couche cireuse, de glandes salines ou d’une
couche protectrice, avec une surface variant entre 4,3 et 508,4 µm².
Stomates : de types et densités variés (de 1 à 32 stomates/mm²) afin de limiter la
perte d’eau.
Feuilles : étroites, plates, charnues ou couvertes de poils, adaptées à la rétention
d’eau.
Tige : dressée, rampante, épaisse ou flexible, jouant un rôle dans la résistance à
la sécheresse et le stockage de l’eau.
