Internet banking is constantly expanding in terms of content and functionality, and it has a significant impact on society. One goal of the Digital Agenda for Libya is to make Internet banking services available to all, reducing cash handling. Internet banking is a critical service that financial institutions provide to their customers in order to facilitate easier and faster access to financial services and transactions. Banks currently spend vast sums of money on the development and maintenance of websites and backend systems that provide clients with Internet banking services. Given the low accessibility of bank websites, evaluation and monitoring of the efficiency of those banking sites that offer the service are needed. The effect of moderating factors on online banking usability assessment in Libya is discussed here. As the Internet grows in popularity, banks are adopting technologies to create their own Web sites. The design of the website is an important factor in determining whether or not visitors will return to the site. Thus, the purpose of this study is to investigate the usability of the Internet banking Web sites of two main banks in Libya. The evaluation procedure is used in the World Wide Web environment to measure real data and obtain response time. To get results on the performance of a Web site, some data from the calculation of page size, composition, structure, and download time has been measured. In this study, a website performance evaluation tool, Dareboost, was used to evaluate the Bank of Commerce & Development website and Wahda Bank website. Dareboost has a- modern graphical user interface that is very easy and intuitive to use and gives a recommendations on how to improve the performance as the result. Based on the observation results, the Bank of Commerce & Development website received the highest score in most metrics. Therefore, the Bank of Commerce & Development website is the best in terms of usability.

The paper describes the mix method and the results of the influence of nanoparticles of nano silica (NS) (d ≈ 65 nm) on the Ultra-High performance Concrete (UHPC) matrix properties. Five different contents of NS particles were applied: 0, 0.5, 1, 1.5, and 2 wt.% by weight of cement. The studies regarding different physical and mechanical parameters of cementitious composite matrix specimens such as water absorption, porosity, compressive strength and flexural strength. Structural properties have been carried out and the results of these studies are presented and discussed. It was shown that the nanoparticles in the amounts of 1-2 wt.% can influence the cement hydration process and thereby enhance the compressive strength of cementitious composite. The higher enhancement was obtained during the first three days of hardening due to so called filling effect. In the following stage of hydration, the strengthening effect diminished. This phenomenon was convergent with the XRD analysis, which proved that the nanoparticles react with the cement paste components.

Since computers have become widely used, programming has become a critical skill. Programming languages are built upon English language words and phrases. It is possible that this could make learning an English-based programming language for non-English language speakers especially challenging. In actuality, the literature did not say much. While many focused on solutions to teaching programming, and some researchers focused on the problems that led to these solutions, very few researchers made any distinction between the language capabilities of novices. Based on the literature, this research study highlights issues that directly influence beginners learning programming, looking particularly at the difficulties faced by those that do not have English as a first language. The methodological approach used in this research is a mixed methods design, with the questionnaire method for data collection in both CQUniversity in Australia and Sebha University in Libya, with experienced programmers and novice programmers in various stages of their study. These data were categorized and analysed to identify areas of difficulty. It became clear that there was a difference. While Australian students identified issues with loop statements (Do...While) and other program logic, Libyan students identified the major problem to be error messages and their interpretation, with over 71% of students identifying this as a problem. However, error messages were mentioned by just 2% of participants at CQUniversity. It was clear that English was a problem.

The present study was conducted to investigate the possible protective effect of Moringa oleifera leaves powder on Hydroxychloroquine induced kidney tissue injury. White male rats were used, and dried Moringa leaf powder was given to them with lunch for 3 weeks to play a protective role in the body, they were dosed orally by tube prepared daily for 5 days with hydroxychloroquine in different doses (1000, 500,250 mg /kg b.wt). Urea and creatinine levels were determined in the serum in addition to the histopathology of the kidney, and the hematological effects were determined for this medicine in the rats. The results showed a significant increase in the urea level and the concentration of creatinine in rats that had been given hydroxychloroquine compared to normal and treated groups with M. oleifera. Also, treatment with M. oleifera showed a very significant drop in urea level. There was an apparent change in the urea level with experience. A significant increase in the count of RBCs was recorded for the hydroxychloroquine group concentration of 1000 mg/kg, compared to the control group and the other groups. And that recorded significant increase in the content of Hb and count of Platelet was recorded for the hydroxychloroquine group concentration 1000 mg/kg, compared to the control group and the other group's .at P value < 0.05. The effects of tissue degradation by hydroxychloroquine were improved when treated with Moringa oleifera leaves powder.

Background: S. aureus is a major pathogen and the predominant bacteria that causes hospital-acquired infections. TiO2NPs have unique characteristics and expanding use for different applications in nanomedicine and have attracted enormous interest in the various rising nanoproducts. Objective: To evaluate the anti-bacterial and anti-biofilm activities of TiO2NPs alone and in combination with the macrolide class of drugs (Erythromycin) against S. aureus isolated from different clinical specimens. Methods: Kirby-Bauer’s disk diffusion technique was applied for antimicrobial susceptibility testing against S. aureus isolates. The Minimum inhibitory concentrations of TiO2NPs and erythromycin were performed with the broth microdilution method, while biofilm formation was investigated by the Calgary technique. Results: At a total of eighty-five strains of S. aureus clinical isolates from patients who are in hospitals in the medical city of Baghdad, 34 (40%) of S. aureus were sensitive to penicillin class (Methicillin) while 51 (60%) were resistant to methicillin, with statistical significance between both groups (P <0.05). In urine samples, the majority of S. aureus isolates were 21 (24.7%), followed by sputum with 14 (16.5%) samples. Patients infected with S. aureus were significant among age groups of 45–54 years old and patients with Ages between 15 and 35 indicate a lower susceptibility to S. aureus infection.mThe results showed that the prevalence of infection with S. aureus was significantly higher among female patients 30 (35.3%) rather than male patients 21 (24.7%), and the male/female ratio was 0.46/1. Vancomycin and imipenem were the most active antibiotics against MSSA and MRSA, with sensitivity of 85 (100%) and 82 (96.5%) for vancomycin and imipenem, respectively, whereas MRSA and MSSA exhibited marked resistance to ciprofloxacin and azithromycin, with sensitivity of 64 (75.3%) and 38 (44.7%), respectively.mTiO2NPs showed excellent biofilm inhibitory activity against MRSA and MSSA isolates, and results showed that TiO2 NPs alone with ½MIC can inhibit biofilm formation by about 40% of MRSA and about 60% of MSSA. Moreover, the combination of TiO2 NPs with erythromycin inhibits biofilm formation by approximately 80–90% for MRSA and MSSA, respectively.

One of the most important concerns is the presence of heavy metals in water. Heavy metal pollution in groundwater is a major concern, because of their toxicity and hazard to human life and the environment. The aim of this study was to determine the quantity of five heavy metals present in groundwater wells in different sites of El-Beida city. Groundwater wells samples were collected in January 2022 from 10 randomly selected wells throughout the region and analyzed in order to determine the content of a number of heavy metals namely: Lead, Copper, Iron, Manganese, and Nickel using an Atomic Absorption Spectrophotometer (AAS), and their levels were compared to the maximum contamination limits specified by the World Health Organization (WHO) and the Libyan National Centre for Standardization and Metrology (LNCSM). The results in the current study indicate there is variation among wells. The Lead (Pb) concentrations ranged between (0.33-0.50 mg/l), whereas the Copper (Cu) value ranged (0.07-0.12 mg/l), the Iron (Fe) value ranged (1.15-1.35 mg/l), the Manganese (Mn) value ranged (0.17-0.75 mg/l), and the Nickel (Ni) value ranged (0.19-0.52 mg/l). Most of the heavy metal analyzed in this study were exceed permissible limits for international standards of drinking water by WHO or LNCSM while Copper (Cu) did not exceed permissible limits for international standards of drinking water.

Potassium bromate (KBrO3) is used as a food additive mainly in the bread-making process. Ruta chalepensis (R. chalepensis) is an excellent and valuable bioactive plant that produces a range of complex flavonoids. The present study was aimed to investigate the possible protective and therapeutic effect of R. chalepensis against KBrO3 toxic effects on rat testis using histopathology investigation. Fifty adult male albino rats were used in the present study. The rats were divided into five groups each containing 10 rats. First group was kept as control, second group received oil extract of R. chalepensis, third group was treated with KBrO3, forth group (Protective group) and fifth group (Therapeutic group). All groups of animals were sacrificed at 2 and 4 weeks. The results of the present study showed that the administration of R. chalepensis caused disarrangement of spermatogonia throughout the lumen of seminiferous tubule. Additionally, abnormal widening of interstitial spaces with degeneration of interstitial cells. There was necrosis to the spermatocytes with inhibition of the spermatogenic process. KBrO3 group showed necrosis of seminiferous tubule, loss in some spermatogenic cells. There were fibrous stroma between the seminiferous tubules. Also revealed vacuolation, edematous, hyalinization and loss of interstitial connective tissue cell with haemorrhage between seminiferous tubules. Protective group showed seminiferous tubule atrophy, disrupted germ cell layers and disappearance of Leydig cells. The therapeutic group, showed interstitial hemorrhage, with necrosis in spermatogonia and vacuolation. It may be concluded that KBrO3 is toxic to testis and R. chalepensis at the tested dose is not beneficial as protective and curative agent.
