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.

The role of agriculture in the transfer of drug resistant pathogens to humans is widely debated and poorly understood. Escherichia coli is a valuable indicator organism for contamination and carriage of antimicrobial resistance (AMR) in foods. Whilst whole genome sequences for E. coli from animals and associated meats are common, sequences from produce are scarce. Produce may acquire drug resistant E. coli from animal manure fertilizers, contaminated irrigation water and wildlife, particularly birds. Whole genome sequencing was used to characterize 120 tetracycline (TET) resistant E. coli from store-bought, ready-to-eat cilantro, arugula and mixed salad from two German cities. E. coli were recovered on the day of purchase and after 7 days of refrigeration. Cilantro was far more frequently contaminated with TET-resistant E. coli providing 102 (85%) sequenced strains. Phylogroup B1 dominated the collection (n = 84, 70%) with multi-locus sequence types B1-ST6186 (n = 37, 31%), C-ST165 (n = 17, 14%), B1-ST58 (n = 14, 12%), B1-ST641 (n = 8, 7%), and C-ST88 (n = 5, 4%) frequently identified. Notably, seven strains of diverse sequence type (ST) carried genetic indicators of ColV virulence plasmid carriage. A number of previously identified and novel integrons associated with insertion elements including IS26 were also identified. Storage may affect the lineages of E. coli isolated, however further studies are needed. Our study indicates produce predominantly carry E. coli with a commensal phylogroup and a variety of AMR and virulence-associated traits. Genomic surveillance of bacteria that contaminate produce should be a matter of public health importance in order to develop a holistic understanding of the environmental dimensions of AMR.
