human operations occur frequently around the Nile Valley. Moreover, where these features were initially
created, their relevance focuses on how the urban communities responded to the processes. So, a ground
penetrating radar (GPR) field survey was carried out on different paleoenvironments of Pre-Quaternary and
Quaternary sediment around Assiut. Deep and critical analyses of georadar facies were made to obtain clear
images of these features with unprecedented resolution. The main objective of this study is to find some
reasonable geological interpretations for these features. From this study, it is possible to identify and differentiate
these features originating from different geological environments and climatological conditions in arid regions
such as those around Assiut. In addition, the study serves as guidelines for environmental management and
climatic changes for enhancing knowledge of urban development. Also, the study demonstrates how georadar
can be used to create precise images of intricate shallow subsurface anatomy with possible palaeoenvironmental
and palaeoclimatic indicators

The early Cretaceous formations in recent years are considered significant potential hydrocarbon-bearing rocks in many rift basins such as Komombo, south Egypt. Therefore, this study is focused on the critical analysis and interpretation of well logging together with seismic reflection data on the Al Baraka petroliferous reservoir in the Komombo subbasin. The interpretation of these data was used to construct the first 3D geophysical models in this area which were subsequently interpreted in terms of their potential to be hydrocarbon-bearing or not. The 3D petrophysical models were deduced to illustrate the spatial distribution and propagation of the petrophysical properties (laterally and vertically) within the reservoir. Additionally, 3D seismic models were prepared to get a comprehensive, in-depth picture of
how the productive hydrocarbon reservoir zones are structurally controlled in different depths. So, these models are crucial for explaining reservoir characteristics and providing supported geological reservoir models for precise reservoir performance prediction. This study aims to differentiate and determine hydrocarbon potential zones in terms of the petroleum system. The results of these progressive  analyses showed that only two zones (C and D) in the Six Hills Formation are considered the most productive zones because they have a large thickness of sand bodies, low-water saturation values, high porosity, and high permeability. These zones are located in the northeastern and central parts of the studied area, which represent the depocenter of the subbasin. This evidence supported and confirmed the presence of petroleum accumulations in certain zones within the Six Hills Formation. Therefore, this work can give and encourage experts with adequate knowledge to understand the development of the rift basins in Komombo and other basins in middle and south Egypt.

1. ​​​​​​​​​​​​​​​​​​​​​​​​​​​​This theoretical study aims to explore the dynamics of a Casson
2. nanofluid flowing through a biological tissue under the influence of a
3. magnetic field, in the presence of an inclined circular cylindrical lymphatic
4. vessel. The governing partial differential equations and their boundary
5. conditions are transformed into a set of non-linear ordinary differential
6. equations using appropriate similarity transformations. The problem is
7. solved using the bvp4c function in MATLAB software, and the numerical
8. results are presented graphically. The research investigates and visually
9. depicts the impact of various parameters on the velocity of the nanofluid, its
10. temperature, and the concentration of nanoparticles. These parameters
11. encompass the magnetic field, porous medium, inclination angle,
12. thermophoresis, thermal Grashof number, Eckert number, mass Grashof
13. number, Casson parameter, and the curvature parameter. The study
14. concludes that an increase in the value of the Casson parameter significantly
15. elevates the NP concentration while concurrently reducing the temperature
16. of the nanofluid. We also found that there is a decreasing trend in both the
17. nanofluid temperature and the NP concentration. The two variables peak in
18. the tissue and then drop close to the lymph channel wall.

Structural, mechanical and ferromagnetic characteristics of hydrothermally synthesized Cd0.4Mn0.6XO nanocomposites were investigated. The characterization of Cd0.4Mn0.6XO was accomplished using XRD, TEM, FTIR, photoluminescence and VSM techniques. The XRD showed the formation of monoclinic Cd2Mn3O8 alongside other phases. The crystallite size has no systematic trend against the valence state of ions. The particle size has minimum value (9.75 nm) for ZnO, and maximum values of 31.39 nm and 35.61 nm were observed for Al2O3 and Fe2O3, respectively. Similarly, typical enhancements are achieved for the mechanical and ferromagnetic parameters, e.g. they are increased when ZnO is replaced by Al2O3 and significantly enhanced by Fe2O3. In contrast, they were reduced by the other X, but they are still higher than ZnO. The photoluminescence of Cd0.4Mn0.6XO shows violet, blue, green, and orange emissions. The reported results indicate a strong correlation between the mechanical and ferromagnetic properties of nanocomposites against the particle/crystallite sizes and valence state.

In this paper, we derive some classical and fractional properties of the rRs matrix function
by using the Hilfer fractional operator. The theory of special matrix functions is the theory of
those matrices that correspond to special matrix functions such as the gamma, beta, and Gauss
hypergeometric matrix functions. We will also show the relationship with other generalized special
matrix functions in the context of the Konhauser and Laguerre matrix polynomials.
