In this study by using the Newman-Janis algorithm, we obtained a rotating version of the quantum-corrected charged black hole. The quantum correction appeared to reveal the black hole event horizon and ergosphere. Also, we investigated the impact of the various parameters controlling this black hole, such as quantum correction α , electric charge Q, and rotational parameter a, on the system thermodynamics. In addition, the analysis of the heat capacity showed that this quantum correction alters the local stability of our system.
At the NE edge of the Saghro inlier, the Tassafte mining district represents a promising area to understand the AgHg-Cu mineralization history of the Anti-Atlas belt. The area is located at the Ediacaran-Cambrian transition, where the ore mineralized bodies are hosted within Ediacaran volcano-sedimentary succession of the Ouarzazate Group and also continue within the Cambrian sedimentary sequences. Ore bodies occur in E-W striking structures, ranging from N80 degrees to N120 degrees, which dip 50 degrees-80 degrees to the south and rarely to the north. Mineralization is controlled by two tectonic stages within the E-W trending structures: a) right lateral shearing, syn-kinematic with centimetric quartz veins (QzII); and b) left lateral movement syn-kinematic with barite and calcite veins. Ore microscopy investigation illustrates a multistage ore including; i) the first stage, represented by microcrystalline quartz (QzI) and euhedral pyrite crystals, arsenopyrite and rare cobaltite crystals are also recognized; ii) the second stage which represents the main ore stage in which the most important Ag and Cu were deposited. It is represented by coarse geodic quartz (QzII), associated with chalcopyrite that occurs in veinlets. In addition, rare galena and sphalerite are also observed. This is followed by chalcocite which exhibits tiny veins and also replacing the chalcopyrite. The silver mineralization occurs in minute veins and in the corrosion zone, replacing the preexisting sulfide minerals. Silver mineralization comprises Ag-sulfosalt, Ag-sulfide, Ag-Hg amalgam and rare native silver; iii) centimetric veins of barite and carbonate, followed by zonal quartz (QzIII) which is associated with second generation of chalcopyrite, galena and also rare sphalerite; and iv) supergene alteration stage. The Tassafte mining area shares several common points with other Ag-Hg ore deposits in the Anti-Atlas. These points comprise comparable Ediacaran volcanic host rocks with a young Cambrian host rocks in The Tassafte area, E-W trending ore veins, and also analogous ore mineralogy. The mineralization studied here are related to post Cambrian tectonism and assumed likely associated with Variscan and Mesozoic tectonic events.

Origanum compactum Benth (Lamiaceae), known locally as ’’zaatar’’ one of five Origanum species endemic to Morocco, is relatively widely distributed in Morocco, particularly in the Rif region (Northern Morocco) and in the middle and high Atlas. This study aimed to investigate the chemical composition and antioxidant potential of aqueous extracts from the Origanum compactum (Benth) leaves. Qualitative profiling was carried out using ultra-high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (LC-QTOF-MS). Furthermore, the antioxidant capacity was assessed through the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay and the ferric reducing antioxidant power (FRAP) test. The results obtained showed an important antioxidant capacity with an IC50 of 31.32 ± 0.13 µg/mL for DPPH assay and 193.75 ± 1.47 AAE/g DM (expressed as ascorbic acid equivalent per g of dry matter) for FRAP assay. Through LC-QTOF-MS analysis, a total of 29 phenolic compounds were characterized across several chemical classes, among which salvianolic acids A and B, rosmarinic acid, and chlorogenic acid were identified as the major constituents. This study revealed that Origanum compactum (Benth) extracts contain various phenolic compounds and display potential as natural antioxidant agents for preventing oxidative stress.
LetR be a commutative ring with identity andS a multi-plicative subset ofR. In this study, we introduce the con-cept of rings in which every ideal disjoint withS isS-almostprime. We investigate the possible transfer of the above ringproperty in the quotient rings, localizations, direct products,trivial ring extensions, and amalgamation algebra.
