This article’s objective is to progress the field of generalized fuzzy topological spaces, particularly generalized fuzzy T0 spaces. Various types of these spaces are introduced and examined. We investigate their hereditary, productive, and projective properties, and demonstrate that these properties are preserved under bijective generalized fuzzy
continuous generalized fuzzy open mappings. Additionally, we explore these concepts in the context of initial and final generalized fuzzy topological spaces.

Although aluminum is an extremely versatile material and can be manufactured and used for a wide range of industrial purposes, it has a limited resistance to corrosion. Hence, the efficacy of two linear biopolymers, keratan (Ker) and chitosan (Chi), was explored, for the first time, as ecologically safe metallic corrosion inhibitors (CIs) for Al in 1.0 M NaCl solution at different temperatures. For performing this study, several experimental and theoretical methods were applied. By combining these methods, it was confirmed that the investigated biopolymers were set to be effective inhibitors for Al corrosion in 1.0 M NaCl solution. Using a 500 mg/L dose of CIs, inhibition efficiencies (% IEs) of 92.7 % and 86.4 % were achieved for Ker and Chi, respectively, indicating their strong adsorption on the metal surface. Thermodynamic and kinetic investigations signified that the adsorption was founed to be physical and obeyed the Langmuir isotherm. The kinetics and mechanism of Al corrosion as well as its inhibition by the tested biopolymers were inspected. The results demonstrated that these biopolymers behaved as mixed-type and interface-type inhibitors. To investigate the inhibition mechanism, theoretical quantum chemical methods were also applied. The experimental investigations were validated by theoretical computations

The purpose of this research is to investigate the palynofacies analysis and palynomorph assemblages of the Salam-53 well, Shushan Basin, north-western Desert, Egypt to show the shelf conditions throughout the Upper Cretaceous deposits, where two palynofacies types have been documented based on the properties components of palynofacies of the studied ditch cutting samples. PF-1, the upper Bahariya clastic-carbonate layer, and the Abu Roash "G" as well as "F" to "C" members were discovered in the inner shelf setting, marine transgression occurs at the late Cenomanian-Turonian dominated by reducing (suboxic-anoxic) settings with occasional local oxic-dysoxic conditions. The global late Cenomanian marine transgression was primarily responsible for this relative sea level rise. PF-2 represents the remainder of the carbonate section ("B" and "A" members) of the Abu Roash and Khoman formations, which were deposited in middle shelf environments with prominent suboxic-anoxic conditions during a major regional marine transgression, which was primarily associated with the global Turonian-Maastrichtian eustatic sea-level rise. Furthermore, palynofacies analyses were used to reconstruct the vegetation cover and palaeoclimatic conditions at these times, indicating that regional warm and relatively dry climatic conditions prevailed. This based on the presence of Afropollis jardinus, Classopollis spp., Ephedripites spp., Elaterspores, and pteridophytes, indicating a paleoenvironment in which parent plants inhabiting wetlands in a humid condition, developed near the well site.

Kojic acid is a wonderful fungal secondary metabolite that has several applications in the food, medical, and agri culture sectors. Many human diseases become resistant to normal antibiotics and normal treatments. We need to search for alternative treatment sources and understand their mode of action. Aspergillus flavus ASU45 (OL314748) was isolated from the caraway rhizosphere as a non‑aflatoxin producer and identified genetically using 18S rRNA gene sequencing. After applying the Box‑Behnken statistical design to maximize KA production, the production raised from 39.96 to 81.59 g/l utilizing (g/l) glucose 150, yeast extract 5, KH2PO4 1, MgSO4.7H2O 2, and medium pH 3 with a coefficient (R2) of 98.45%. Extracted KA was characterized using FTIR, XRD, and a scanning electron microscope. Crystalized KA was an effective antibacterial agent against six human pathogenic bacteria (Bacillus cereus, Staphylo coccus aureus, Escherichia coli, Klebsiella pneumonia, Serratia marcescens, and Serratia plymuthica). KA achieves high inhibition activity against Bacillus cereus, K. pneumonia, and S. plymuthica at 100 μg/ml concentration by 2.75, 2.85, and 2.85 compared with chloramphenicol which gives inhibition zones 1, 1.1, and 1.6, respectively. Crystalized KA had anticancer activity versus three types of cancer cell lines (Mcf‑7, HepG2, and Huh7) and demonstrated high cytotoxic capabilities on HepG‑2 cells that propose strong antitumor potent of KA versus hepatocellular carcinoma. The antibacterial and anticancer modes of action were illustrated using the molecular docking technique. Crystalized kojic acid from a biological source represented a promising microbial metabolite that could be utilized as an alternative antibacterial and anticancer agent effectively.
