摘要 ：
The current study aims to investigate the effects of thermal radiations in a porous bulb-shaped enclosure. The cavity is filled with Casson fluid, the upper highlighted section represents the hot wall, while the lower highlighted part signifies the cold wall, and the bottom section corresponds to the adiabatic wall. The research takes into account several key variables such as the Hartmann number (varying from 0 to 20), Lewis number (ranging from 0.1 to 10), Rayleigh number (Ra 10(3)-10(5)), Casson fluid parameter (varying from 0.1 to 10), buoyancy ratio (ranging from 0 to 2), Darcy number (ranging from 0.1 to 0.001) and thermal radiation parameter (varying from 0 to 5). In two dimensions, the governing formulation is written as a set of balancing equations for velocities, pressures, energies and concentrations. The nonlinear governing PDEs are solved using numerical approach based on finite element method (FEM). The discretization is performed using the stable finite element pair P-2/P-1. To analyze the effects of flow distribution changes, we graphically display those using streamlines, isothermal profiles and isoconcentration patterns. Information on kinetic energy, local heat and mass flux is also provided in the form of graphs and tables. The findings suggest that thermal radiation and porosity factors have profound impact on the flow pattern, isothermal and isoconcentrating contours. The study demonstrates the applications in solar thermal power conversion, energy deficiency systems and many other application of electronics designs.

摘要 ：
Purpose: The current study aims to enhance the double diffusive natural convection in an Ostwald -de Waele fluid filled in a hexagonal enclosures using non -uniform magnetic field embedded with circular obstacle. The upper wall has maximum temperature ( T*) and concentration (C*h) whereas the lower wall is kept at minimum tem) and concentration (C*h perature ( T* ). The parameters that play a significant role in the heat and mass transfer c c are evaluated, including Hartmann number, power law index, Rayleigh number and buoyancy ratio. Design/Methodology/approach: In two-dimensions, the governing formulation is written as a set of balancing equations for velocities, pressures, energies and concentrations. The nonlinear governing PDEs are solved using numerical approach based on Finite Element Method (FEM). The discretization is performed using the stable finite element pair P2/P1. Code validation and results are ensured by conducting a grid convergence and comparison test respectively. Findings: The influence of flow on velocity, isotherms and iso-concentration field is examined by analyzing a broad variety of variables such as power-law index (0.7 <= n <= 1.2), Hartmann number (0 <= Ha <= 50), Rayleigh number 104 <= Ra <= 106, inclination angle 0 degrees <= gamma <= 90 degrees and buoyancy ratio ( - 2 <= N <= 2). The findings are displayed graphically, including the flow, temperature and concentration fields. Heat and mass transfer rates are maximum for shear thinning fluids while for shear thickening fluids it reduces, whereas it is maximum for concentration dominated assistant flow and minimum for concentration dominant counter flow. Application: The novel aspects of the research include its thorough examination of solar thermal power conversion and its inventive energy deficiency devices and a wide range of electrical design applications.

摘要 ：
For any triangular matrix coalgebra gamma = ((C U)(0 D)) , in this paper, we first examine some connections between coalgebra properties of gamma and its constituent coalgebras C, D, which contain semiperfectness, computability and row/column-finiteness of their left Cartan matices. Then we devote to considering the coresolution dimensions of recollement of comodule categories by investigating covariantly finite subcategories.

摘要 ：
We describe the Gorenstein derived categories of Gorenstein rings via the homotopy categories of Gorenstein injective modules. We also introduce the concept of Gorenstein cosilting complexes and study its basic properties. This concept is generalized by cosilting complexes in relative homological methods. Furthermore, we investigate the existence of the relative version of the Bongartz's theorem and construct a Bongartz's complement for a Gorenstein precosilting complex.

摘要 ：
n-Igusa-Todorov algebras are closely related to the finitistic dimension conjecture. Each n-Igusa-Todorov algebra has finite finitistic dimension. In this article, we find some new criteria for algebras being n-Igusa-Todorov algebras (here n = 0, 1). As applications, we extend the proof of the finitistic dimension conjecture to several new classes of algebras.

摘要 ：
Let Gamma be a Gorenstein coalgebra over a filed k. We introduce the Gorenstein transpose via a minimal Gorenstein injective copresentation of a quasi-finite Gamma-comodule, and obtain a relation between a Gorenstein transpose of a quasi-finite comodule and a transpose of the same comodule. As an application, we obtain that the almost split sequences are constructed in terms of Gorenstein transpose.

摘要 ：
Tilting theory plays an important role in the representation theory of coalgebras. This paper seeks how to apply the theory of localization and colocalization to tilting torsion theory in the category of comodules. In order to better understand the process, we give the (co)localization for morphisms, (pre)covers and special precovers. For that reason, we investigate the (co)localization in tilting torsion theory for coalgebras.
