Electronic management is considered as one of the basic components of the information system, and one of the means that has caused a great stir in our present era, as the need for it has become very urgent and necessary in various fields and sectors, especially in the management of the education sector, as it represents one of the quality standards (the use of technical means in the institution educational), therefore, the aim of this research is to closely identify its concept and explain its importance in the success of managing educational institutions in all their administrative, educational and office aspects. In this research, some basics were presented as an introduction to the topic under study to ensure clear understanding. The research also pointed out some of the challenges and obstacles facing the application of electronic management and proposed solutions to overcome these obstacles.   The researchers used the descriptive approach to suit the research objective. Various sources were reviewed, including research articles, books, and reports

Clostridioides difficile is widely recognised as one of the most common causes of healthcare-associated C. difficile infections due to the ability of spores to survive for prolonged periods in the hospital environment. This study aimed to evaluate the efficacy of UV-C 254 nm light in the inactivation of the spores of different C. difficile ribotypes on brain heart infusion (BHI) agar plates or in phosphate-buffered saline (PBS) with varying spore densities. Furthermore, the effectiveness of a sporicidal surface disinfectant against C. difficile spores was determined on different surfaces. Spore suspensions of different C. difficile strains in the range of 10⁵–10⁷ colony-forming units (CFUs) mL⁻¹ were inoculated on BHI agar plates or in PBS and exposed to UV-C light for up to 30 min. Additionally, a spore suspension of 10³–10⁵ CFUs was spread over a 1 cm² test area on different surfaces, and sporicidal surface wipes were used according to the manufacturer’s instructions. The findings demonstrated that spores of C. difficile ribotypes exhibited a complete reduction in log₁₀ CFU on BHI agar plates and PBS following 20 min of exposure to a UV-C dose of 2208 mJ cm⁻². The surface wipes with sporicidal properties demonstrated efficacy in reducing the number of C. difficile spores on the Formica, stainless steel, and plastic surfaces by 2.03–3.53 log₁₀. The present study demonstrates that moist surfaces or liquids can enhance the efficacy of UV-C treatment in reducing C. difficile spores. This approach may be applicable to the surfaces of healthcare facilities and to water disinfection systems.

Abstract

For the first time in Libyan flora, a new record for Boerhavia repens L is recorded. This widespread wild weed was collected from the Ariggiba region (110 km west-south Sabha city). A full description, habitat information, distribution map, and distribution data are provided to facilitate further identification and future detection. A brief discussion about the most important threats this species poses is presented.

applications of complexes are very important in different sectors like the pharmaceutical industrial. So, this study aimed to preparation sodium salts of amino acids complexes by using K2PtCl6, Cu (NO3)2.3H2O, HgCl2 and ZnCl2 as a ligand reaction with the sodium salts of the following amino acids: glycine (glyH), L-alanine (alaH), L-phenylalanine (pheH). The following complexes were isolated: Na [Pt(gly)Cl4] .0.5C2H5OH, [Cu(ala)2].0.5C2H5OH, [Pt(ala)3Cl].C2H5OH.4H2O, [Pt(phe)2Cl2].0.5C2H5OH.1.5H2O, [Hg(phe)2].9H2O, [Zn(phe)2].C2H5OH. The isolated complexes have been characterized by their elemental analysis’s solubility, conductivity measurements, IR, electronic absorption and C13 NMR spectra.

Keywords: Metal complexes, Amino acids, Characterization.

Abstract

Vitamin D deficiency is a prevalent health issue among children, with potential consequences for bone health and overall well-being. This study aimed to investigate the prevalence of vitamin D deficiency in a pediatric population and identify associated factors. A cross-sectional study was conducted on 400 children (aged 1-10 years) recruited from medical laboratories in Gharyan City, Libya, between January 2022 and June 2024. Participants were categorized based on their vitamin D levels (deficient, insufficient, adequate, or optimal). Demographic data (age, gender) and vitamin D levels were collected and analyzed using descriptive statistics and two-way ANOVA. Approximately half of the study participants (49.75%) exhibited vitamin D deficiency. Females had a slightly higher prevalence of deficiency (27.5%) compared to males (22.25%). Significant differences in vitamin D levels were observed across age groups. Infants under 12 months had higher levels compared to older children (36-72 months). While gender was not a significant predictor of vitamin D deficiency in our study, previous research has suggested potential gender-related disparities. The findings of this study highlight the concerning prevalence of vitamin D deficiency among children in the region. Age appears to be a significant factor influencing vitamin D status, with younger children being more susceptible to deficiency. While gender may not be a major determinant in this population. The high prevalence of vitamin D deficiency in our study underscores the importance of promoting sun exposure, dietary intake of vitamin D-rich foods, and supplementation strategies to address this public health issue. Further research is needed to explore the underlying factors contributing to vitamin D deficiency in children
