This research was carried out at Kharga and Dakhla, in the western Egyptian desert. The species investigated include basically those of different ecological affiliations as well as different life forms, in order to have comparative indications in the ionic means of adjustment. During winter and summer, the water soluble ions in both soil and plants were analyzed. Also, the total osmotic water potential and the share of ionic radicals of plants were calculated. The data revealed that, halophytic species maintain osmotic adjustment due to accumulation of ions depending on seasonal and species variation and ionic osmotic potential which were related to chlorides, sodium and potassium. The seasonality or location has the dominant effect on Na+, K+, Cl- and SO4-2 concentrations in halophytes Suaeda and Cressa and affected by the interaction (S x L) in case of Z.coccenium. The ionic osmotic potential of Na+/K+ and Cl- / SO4-2 ratios for salt tolerance in studied species were discussed.

Selenium (Se) enhances the resistance of plants exposed to metal stress and can be used to lessen the impacts of toxic elements and to enhance the effectiveness of the plants used to clean up polluted sites. There is no information available about the optimum dose and form of Se to stimulate the camelthorn (Alhagi maurorum Medik) plant, which is one of the plants used in the phytostabilization of toxic elements. The impacts of selenate (Se-VI) and selenite (Se-IV) on the phytoremediation of toxic metals from loamy soils by camelthorn were investigated in a pot experiment. Se-VI and Se-IV were added to the soil at doses of 0, 5, and 10 mg Se kg⁻¹ soil, and each treatment was repeated five times. Se-VI and Se-IV, significantly increased plant growth and nutrient uptake. The addition of Se, either from Se-VI or Se-IV, significantly increased the superoxide dismutase (SOD) and peroxidase (POD) enzymes, and the …

Sabkhas are unique salt flat formations situated along the coastline and have been the subject of extensive scientific inquiry. This study delves into the formation and significance of sabkhas, along the South Red Sea coast of Egypt. Combining field observations, satellite imagery, and GIS analysis, the research unveils the processes shaping these distinct landscapes and their broader impact on the region. The study utilizes Sentinel-2 A imagery and digital elevation models to map salinity and identify optimal methods for salt detection. It further employs advanced data processing techniques to refine land cover classification and identify unique features within four sabkhas along the Red Sea coast: Ras Baghdadi, Marsa Abu Madd, Bir Shalatein-Marsa Himeira, and Diib. Examining these sabkhas reveals intricate details of their topography, hydrology, and sediment composition. The study identifies factors contributing to their individual characteristics, such as structural control, interaction with lagoons, and the influence of wind and aridity. Analysis of satellite data and field observations unveils the presence of salt ponds, dunes, microbial mats, and distinct sediment layers within these formations. Evaporite crystals, halophytic vegetation, and color patterns provide further insights into their formation processes. The study emphasizes that sea level fluctuations, fluvial and aeolian processes, and limited human intervention have shaped the temporal evolution of these sabkhas. However, climate change poses significant future challenges. By highlighting the importance of understanding and preserving these ecologically and economically valuable ecosystems, this research underscores the urgent need for their protection in the face of a changing climate

This paper introduces a novel generalization of the Mittag-Leffler function, delving into its fundamental characteristics. The analysis encompasses a thorough exploration of its properties, including the derivation of recurrence relations, differential formulas, and various integral representations such as the Euler, Laplace, Mellin, Whittaker, and Mellin–Barnes transforms. Furthermore, the study establishes connections to other significant special functions, expressing the new generalization in terms of the Fox-Wright function, the generalized hypergeometric function, and the H-function. The paper also defines associated fractional integral and differential operators, highlighting the function’s relevance to fractional calculus. Several noteworthy
special cases are derived from the main results, demonstrating the breadth and adaptability of this new function. This research provides a comprehensive framework for understanding the properties of this generalized Mittag-Leffler function and suggests its potential for applications in diverse areas, particularly within the realm of fractional analysis and its related fields.

Given the growing quantity of proposals and works of basic hypergeometric functions in the
scope of q-calculus, it is important to introduce a systematic classification of q-calculus. Our aim in this article is to investigate several interesting q-partial derivative formulas, q-contiguous function relations, q-recurrence relations, various q-partial differential equations, summation formulas, transformation formulas and q-integrals representations for basic Humbert hypergeometric functions Φ1, Φ2 and Φ3 under constraints of symmetry parameters. These interesting properties, as special cases, include many known expansions of
basic Humbert hypergeometric functions Φ1, Φ2 and Φ3, and are also include particular interest in the area.

The present paper discusses a study of a class of Charlier matrix polynomials (CMPs) and its generalized analogue. Certain generating matrix functions, recurrence matrix relations, matrix differential equation, summation formulas and many new results have been discussed for these matrix polynomials. Weisner’s group theoretic method is used to obtain matrix generating relations for Charlier matrix polynomials and the details of this method were given in this paper. Finally, we will discuss only briefly the procedure followed.
