Abstract

Melting point, FTIR, chromatography analysis, and physical properties were used to determine the structures of new heterocyclic compounds that contained 4-aminoantipyrine, which was thought to be a crucial step for the synthesis of some new derivativesGram-positive and gram-negative bacteria (Staphylococcus aureus and Streptococcus mutans) and Shigella flexeneri and Pseudomonas aeruginosa) are evaluated for their antibacterial activity using these substances. Academics and medical applications have shown a great deal of interest in the antipyrine derivatives, which are a popular structural motif among heterocyclic compounds with three nitrogen heteroatoms. Although they are not found in nature, they are used extensively in drug development, organic synthesis, chemical biology, polymer chemistry, and supramolecular chemistry. As a result, developing a straightforward and easy method for the production of antipyrine derivatives is crucial. In contrast to conventional antibiotics, The findings demonstrated the strong antibacterial qualities of each of these substances. Additionally, we discovered that they can induce pro-inflammatory cytokines like IFN-γ, which are released by CD4+ T helper 1 (Th1) cells, to have an immunological effect in vivo in an animal model.. Therefore, this study aims to synthesize some novel derivatives and evaluate their antibacterial activity by examining their capacity to induce the cellular immune response and the histopathological changes in the experimental rabbits' splenic sections.

Abstract

The study focuses on the role of water in reducing radiation exposure during FDG PET/CT scans. Water consumption prior to the scan hydrates the body, improves blood circulation, and facilitates efficient distribution uptake of the radioactive tracer, FDG. This leads to more accurate detection of areas with high metabolic activity, such as cancer cells. Furthermore, water reduces the concentration of residual FDG in the bladder or kidneys, having a low radioactive count during the image capture. After the scan, isotonic is achieved with aid of water to eliminate any remaining FDG as a move towards minimizing radiation consequences. The research also focuses on the type of radiation, dividing it into ionizing radiation and non-ionizing radiation as well as the hazards of radioactive substances. The paper explores the nature of tumors, the working of PET and CT equipments, and synergistic impact of PET/CT. Pet: The focus is on one more radioactive material – FDG which is used widely in pet scan and its properties like half-life, shelf-life, composition and where it gets energy from.

Abstract

This research investigates the effect of adding recycled rubber to concrete mixes as part of efforts to enhance environmental sustainability and improve the mechanical properties of concrete. The study focuses on evaluating the mechanical and physical performance of rubberized concrete by analyzing its properties such as compressive strength, tensile strength, and workability. Partial replacement of rubber by 0% to 15% of fine aggregate in concrete was studied, with standard tests conducted to determine the effect of rubber on overall performance. The importance of the research lies in providing a dual solution of reducing environmental waste from used tires, while improving some properties of concrete in non-structural applications. The results show that rubberized concrete achieves important advantages such as improved flexibility, abrasion resistance, and light weight, despite a slight decrease in compressive strength. The research also highlights the potential of using rubberized concrete in non-structural applications such as pavements, road barriers, and shock absorption systems. The research concludes by recommending further studies to improve the adhesion between rubber and concrete mix components, while exploring innovative applications to expand the use of rubberized concrete in sustainable construction projects.

Abstract

Coral reefs are complex marine ecosystems consisting of corals (Anthozoa), algae and other organisms (Barnes, 1987). They have an important role in maintaining the balance of marine ecosystems and provide habitat for many species of fish and invertebrates (Odum, 1993). The method used in the coral reef condition survey is the Underwater Photo Transect method. This method is a method for monitoring coral reef conditions. This method is a development of the Point Intercept Transect (PIT), Line Intersect Transect (LIT), and Rapid Reef Assessment (Towing) methods. According to the results of the study, location 2 has the highest percentage of live coral cover category of 16.77%, Furthermore, at location 1, the percentage of live coral was 13.21%, Based on the Decree of the Minister of Environment No. 4 In 2001, it was shown that the coral conditions at both points 1 and 2 were in the poor category. The abundance of coral fish in the Drinking Waters at station I point I has 5 species with an abundance of 46 individuals and an abundance of 0.46 (individuals/m3). Point II station I has 6 species of fish with 52 individuals and an abundance of coral fish 0.52 (individuals/m3).

Abstract

This research investigates the feasibility of employing fermented date seeds (FDS) as an efficient and environmentally friendly adsorbent for removing copper ions (Cu2+) from wastewater. Date seeds, an abundant by-product in date-producing regions, can be managed sustainably by repurposing them as a heavy metal adsorbent from date vinegar production. The vinegar fermentation process partially activates the seeds, enhancing their adsorptive properties. The surface properties of the FDS were analyzed using techniques such as Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and SEM-EDX. The chemical oxygen demand (COD) test is used to evaluate the stability of organic matter in the adsorbent derived from FDS. Batch adsorption studies were conducted to determine the best conditions for Cu ion removal, including contact time, initial metal concentration, adsorbent dosage, and pH level. The FDS adsorption capacity is 4.76 mg g⁻¹, achieved within an equilibrium time of 90 minutes at pH 5 and 25 °C. The isotherm and kinetic models were applied to understand the adsorption mechanism, with results indicating a good fit for Freundlich isotherm and pseudo-second-order kinetics. In addition, the FDS shows effectiveness, with a COD value of 150 mgO2/L. Fermentation stabilizes organic components, reducing leaching risk and improving water treatment performance.

Abstract

GC-MS operates as a robust analytical method that chemistry labs commonly use because it effectively separates chemicals while identifying their components with precise accuracy. Research instruments like GC-MS provide high quality separation and molecular identification which makes them indispensable for environmental studies as well as pharmaceutical insights and forensic investigations and quality control applications. Extensive usage of GC-MS remains incomplete because researchers must develop an organized framework which illustrates system elements and their supporting functions together with application boundaries. The main objective of this research is to establish a systematic examination of GC-MS core functioning and equipment alongside examining operational details and system constraints. The research shows how GC-MS components including injectors, columns, ionization techniques, mass analyzers and detectors function together to achieve optimal performance results. The research presents current uses of GC-MS in environmental monitoring and pharmaceutical analysis and forensic science through methodological examples while supplying reference spectra. This comprehensive study combines GC-MS principles with practice to provide a unified framework which includes reviews regarding recently developed hyphenated methods and ionization approaches and column development. The research results function as a useful guide for scientists as well as practitioners to help them select systems properly and develop methods and advance GC-MS systems for intricate analytical tasks.
