Osteoporosis is the most commonly diagnosed bone disease worldwide, resulting in high morbidity and mortality. It is considered one of the greatest health hazards and is thought to be caused by low bone mass. The Bone Mineral Density (BMD)Test, which measures bone fragility, it is a commonly recommended test for evaluating osteoporosis. A special method called dual energy X-ray absorptiometry (DEXA) of the lumbar spine and proximal femur is used to perform this test. Lack of bone mineral density is still a cause of fractures in certain parts of the body, such as the hip and spine. The study aims to assess osteoporosis detection rate in different regions (lumbar spine and proximal femur) and evaluate the relative risk of osteoporosis to identify optimal and predictable fracture sites. DEXA measurements were obtained using a Hologic QDR4500 (A/SL.DELPHI discovery A/SL/W/C) of the 70 post-menopausal women at Masarra Clinic – Tripoli Libya. The BMD of .

Self-Checking Cache Memory: Enhancing Reliability and Error Detection in digital Systems

Mohamed A. Abufalgha
Cache memory plays a crucial role in modern computing systems by providing fast access to frequently accessed data. However, the reliability of cache memory is of utmost importance to ensure data integrity and system stability. This paper presents a novel approach called "Self-Checking Cache Memory" that aims to enhance the reliability and error detection capabilities of caching systems. The proposed self-checking mechanism is based on the integration of error detection codes within the cache memory architecture. By incorporating an error detection code, the cache memory can identify and report errors that may occur during data retrieval or storage operations. Berger code are explored and evaluated for its effectiveness in detecting errors. Additionally, the paper introduces a parallel check code generation technique by partitioning the cache memory content into two segments: one for data and the other for check bits. It generates the complement of t.

This study aims to explore the extent to which the quality of students who enroll in university colleges affects the quality of final outcomes. This study was conducted on graduates of the Faculty of Engineering at the University of Misurata, using a random sample of 30% with (516) graduates out of a total number of graduates who reached (1695). Graduate from the beginning of the college’s establishment in the year 2000 until the year 2022. The study tool was the review of the historical students records of the Faculty of Engineering, Misurata University, which includes all graduate data, which was analyzed using the simple linear regression method (Simple linear regression) and Test of Normality using Microsoft Excel to analyze data that includes three main elements: (secondary percentage, cumulative average, and graduation period. The results showed that there is a partial effect of the quality of the input (student) on both the cumulative GPA .

Determination the Ability of Fungi Isolated from the Rhizosphere Soil to Produce Indole-3-Acetic Acid Hormone

Hana O. Safar
Indole-3-acetic acid (IAA) is one of the most important and physiologically active plant hormones. This study aimed to isolate fungi from the rhizosphere soil of some vegetable crops grown in Al-Sikt region in Misurata city-Libya to determine their ability in producing IAA hormone. Fourteen species of fungi were isolated using the serial dilution method and cultivation on PDA medium. The ability of isolated fungi to produce IAA hormone were tested on YMB media supplemented with 0.1% L-tryptophan as an initiator to stimulate hormone production. The result showed the ability of four isolates (Alternaria sp., Fusarium sp., Trichoderma sp., Rhizopus sp.) on the production of IAA hormone, which was detected by changing the color of the fungal filtrate to pink after adding Salkowski reagent. The results also showed that the highest level of IAA concentration by reading the absorbance of the fungal filtrate at 530 nm using a spectrophotometer was for Trichoderma sp. at a concentration of 10.5.

This study presents the synthesis and characterization of three copper(II) complexes with the formula [Cu(ASP)2], [Cu(ASP)(PDTC)]and [Cu(ASP)Q] (where, ASP = aspirin, PDTC = pyrrolidine dithiocarbamate, Q = 8-hydroxybenzaldehyde). The complexes were characterized by utilizing FTIR, UV–visible analysis, mass spectra and elemental analysis. The antifungal activity was studied for the free aspirin and its complexes against the fungi Aspergillus Niger. The results showed that the prepared compounds have good activity which decrease in the order Aspirin > [Cu(ASP)2] > [Cu(ASP)(PDTC)]> [Cu(ASP)Q]..
