ABSTRACT The present investigation was undertaken with the aim to study the prevalence and relationship of Waist-Hip Ratio (WHR) and Body Mass Index (BMI) with health risk and their associated socio-demographic correlates in the women. The data was collected from 120 women, aged 30 years and above with a mean age of 47.30 ± 13.20 years (range 30 to 88). The cross-sectional study conducted in 2019 among Sabratha residents. The participants were assessed with anthropometric measurements including height, weight, BMI, waist circumference, hip circumference and WHR. Respondents provided information on their socio-demographic details and health conditions. Prevalence of those who were obese, overweight, normal and underweight based on BMI was 40.0 %, 39.2 %, 18.3 % and 2.5 % respectively. Participants aged 45 years and above were more likely to be overweight and obese compared to those aged 30-44 years. Participants who were none educated were more likely to be overweight compared to complete educated. Participants who were overweight were less likely to have heart problems, while participants who were obese were more likely to have heart problems. Prevalence of those who were high, normal and low based on WHR was 65.8 %, 4.2 % and 30.0 % respectively. Participants aged 45 years and above were more likely to have high WHR compared to those aged 30-44 years. Participants who were overweight and those with a higher WHR were more likely to have heart problems. 

The metallurgical influence of niobium (Nb) on an annealed high manganese (Mn) steel is still an active issue of discussion between automobile companies and steel manufacturers. Some controversy exists in the literature concerning the influence of Nb solubility on microstructure and thereby on mechanical properties. The influence of Nb-solubility on microstructure of Fe30Mn alloy steel was investigated experimentally and by computational materials modeling. Nb was added in 0.05, 0.1, 0.2, 0.4, 0.6 and 1% additions and the alloy samples were annealed at 1200oC for 2, 5, 10, 30 and 60 minutes. The microstructure was investigated using an optical microscope, TEM and SEM-EDX and precipitates were chemically tested. Niobium solubility in Fe30Mn austenite was theoretically studied based on Gladman assumptions and was also examined by Thermo-Calc analysis. The result of this work is a comparison between the microstructure analysis and theoretical studies, and it has been found that Nb was soluble in Fe30Mn austenite phase and has had a solute drag effect where Nb(C,N) and NbN precipitates were seen and the effect was pinning effect 

Quality assurance and institutional accreditation in education is becoming of paramount importance. This study aims to assess the impacts of the accreditation process of the National Center for Quality Assurance and Accreditation (NCAAA) on the quality of education in one of private university in Libya. Methods: The research adopts a descriptive study design in University of Tripoli Alahlia (UTA) where an official accreditation process was completed by the NCQAA during 2017-2019. Data were collected using the self-study report that produced by the NCQAA accreditation committee during the accreditation process, and were retrieved in specific data collection sheet by one of the authors. Results: The NCQAA accreditation process that lasted about 4 years brought significant changes in the educational progressions and made the staff members more aware of quality issues in education. Our findings also reported significant improvements in the quality of education in the university. Conclusions: The process of NCQAA accreditation conducted in UTA has been positively improved the quality of education. Data from other institutions would also expressively increase the relevance and rationality of the study.

ABSTRACT

Massive amounts of solid olive mill residues (olive-waste cake) generated

every year and disposed of in the environment. Thus, the present work aims

to study the preparation of activated carbon (AC) from Libyan Olive-Waste

Cakes as a natural source. The solid olive mill residue was carbonized at

200 C0 and chemically activated with 25% Zncl2 and 25% Zncl2 + 25%

H2SO4 . The prepared AC was used to reduce total hardness in groundwater.

The results showed that the addition of H2SO4 increased the treatment

efficiency of AC leading to decrease the total hardness concentration.

Several parameters affecting the efficiency of AC were investigated

including pH, initial concentration of AC, and contact time. The achieved

results showed that the optimum values were at pH: 3, AC initial

concentration: 2.5 g/L, and contact time 120 min. At these conditions the

maximum reduction of hardness was 75%. According to these results the

olive- waste cake can be considered as an effective natural source of

activated Carbon.

Abstract

Cohesion is one of the most important characteristics of good translation. Having a good translation is not achieved unless this factor is carefully observed. We may find students who have good mastery of spelling, grammatical rules and the skill of speaking but have noticeable weaknesses of using cohesive devices when they translate literary prose texts from Arabic into English. This study tries to examine the use of cohesive devices by University students when they translate literary prose text from Arabic into English. Texts used as a tool or instrument of data collection were given to some students to translate. The participants, in their translations, depended on certain devices ignoring the others. The subjects disregarded completely some categories of cohesive devices, such as the class of possessive pronouns, comparative reference, ellipsis, and substitution. Students sometimes misused the items, such as what happened with ‘the’. Many students were unable to vary the language (expressions) they used to express their ideas. Students sometimes succeeded in achieving cohesiveness but sometimes failed. A number of students did not end the sentences they wrote and started new ones.
