Today’s organisations are under pressure to cut the ICT infrastructure energy costs and also use of ICT infrastructure resources in efficient manners. On other hand organisations ICT infrastructures are expanding rapidly and demands agility in ICT infrastructure solutions, business requirements and in technology change. Virtualization is the most effective way to reduce the energy cost while enhancing efficient utilization of resources and agility. To fulfill these demands organisations are migrating from physical infrastructures to the virtual infrastructures. Where organisations are migrating to virtual infrastructures to deliver the services to business there is also need to consider the right virtual infrastructure fundamentals for efficient service delivery. If the virtual infrastructure is unreliable or experience poor performance such issues are not only causing the problems for virtual infrastructure but also can damage the organisation reputation. This research is based upon Information Technology Infrastructure Library (ITIL), to find the key goals of capacity management and align the capacity management within virtual infrastructure to ensure virtual infrastructure is utilize in the most efficient, predictable and cost effective manner. This research will also investigate the how to apply capacity management best practices to improve performance, reduce operating cost, analyse current capacity, predict future capacity and make sure service level agreements are met

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.

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
