About Faculty of Science

Faculty of Science

The Faculty of Science is the core at the University of Tripoli, as it was the first that established in this prestigious university. It is also the first faculty of science in Libya. At the present, it includes ten scientific departments: Departments of Zoology, Mathematics, Physics, Chemistry, Botany, Geology, Computer Science and Statistics, Atmospheric science and geophysics. It currently works to create a new department of Archaeology in order to study the scientific and research side of the historical heritage of the Libyan people. Graduates of this college have worked in various governmental sectors, such as oil exploration, extraction and refining, chemical industries complexes in Abu Kamash and Ras Al-Anuf, as well as plastics companies in production and manufacturing, and in factories for soap, cleaning materials and others. They were also recruited by the education sector in different research and pedagogical areas.

 

The graduates of this faculty have led the scientific process for many years and still represent the first building block in all colleges of science, and some other colleges in all Libyan universities for the past five decades. The scope of work for graduates included Faculties of Medicine (in the field of basic sciences, biochemistry, anatomy, histology and microbiology), many departments in the Faculty of Agriculture, general engineering, chemical and geological engineering; in particular, medical technology and pharmacy, and the Faculty of Economics and Arts. The Faculty of Science provides teaching assistants to other faculties and universities in the Libyan state.

 

The Faculty of Science is the first to create graduate studies programs in Libya, despite the nature of graduate studies in basic sciences, which need capabilities other than competent professors. Teaching staff in this institution graduated from international universities in the West and the East (USA, UK, Australia, and other European countries). They graduated from universities that are well-known for their high academic standard.

 

Having obtained their first university degree or higher degrees of specialization from Libya or abroad, graduates of Faculty of Science worked for industrial and nuclear research centers, petroleum sector, marine life, biotechnology, plastics, and other specialized research centers.

 

The Faculty has also enriched the scientific research movement in the fields of basic sciences in the Libyan state through the issuance of refereed basic science journal.

Synthesis and Study of Schiff’s Base Ligands Derivedfrom Reaction of Benzil with Aliphatic and Aromaticamines and Their Metal Complexes with Cu(II), Ni(II),Cd(II), Pb(II), Pd(II), Hg(II), and VO2+.

Abstract Five symmetrical Schiff base ligands[four bi-dentate and one tetradentate(L3- L7)] and two un-symmetrical bi-dentate and tri-dentate (L1-L2) ligands with the Nitrogen and oxygen chromophore were isolated inpure form and good yield. The ligands were fully characterized by elemental analyses, melting point, IR, H1- &13C- NMR, and mass spectra.The Schiff bases L1 and L2 were successfully coordinated to Pd(II) and VO2+ ions respectively and these complexes were characterized using elemental analyses, IR and mass spectra. The interesting result by mass spectrum of VO2+ complex of L2 shows parent peak at 524 confirming that the formula of the complex as [VOL2(ac.ac.)2H2O] in which the complex has an octahedral geometry.The symmetrical Schiff bases (L3-L7) were also successfully coordinated to Nickel (II), Copper (II), Lead (II), Cadmium (II), and Mercury (II) ions to form their corresponding complexes. The total twenty five metal (II) XI Schiff base complexes of (L3-L7) were isolated. These complexes were characterized by elemental analyses, melting points, IR, mass spectra technique. 1H &13C-NMR Spectra in DMSO d6 for Pb, Cd, and Hg complexes show the expected number of peaks with deferent chemical shift comparing with the free ligands in the same solvent. The interesting result by mass spectrum of Ni(L7)2 complex compred with of L7 spectra shows parent peak at 977 confirming that the ligand L7 has lost one proton to give the desire complex in square planar geometry.

Estimate the Slope Parameter in Replicated Linear Structural Relationship Model

ABSTRACT---- Replication of observation allows consistent estimation of slope parameter of a linear structural model when the ratio of variances is unknown or when some external information about parameters is not available. In this paper, we look at the way a linear structural relationship model work by replicating observations with two different estimation methods of slope parameter and different cases of existence of outliers. The maximum likelihood estimate (MLE) and a new nonparametric robust estimation method are used to estimate the slope parameter in replicated linear structural relationship model (RLSRM). The simulation studies and the application of real data are used to investigate the performance of the estimated parameters. Keywords— Maximum likelihood method, A nonparametric method, Trimmed mean, Outlier, Linear structural relationship model with replicated.

عزل وتأثير فطر بيوفيريا باسيينا المتلازم للآفات الحشرية المختارة في بعض المناطق بغرب الجماهيرية

تم حصر وتعريف فطر Beauvaria bassiana (Balsamo) في ترب 20 موقعا بالمنطقة الغربية بالجماهيرية العظمى زرعت بمحاصيل مختلفة، وتفاوتت نسب وجود الفطر من منطقة إلى أخرى بسبب امكانية تأثرها بعدة عوامل مثل درجة الحرارة، الرطوبة النسبية، الأس الهيدروجيني، أنواع النباتات المزروعة، أنواع الحشرات الملازمة، والتطبيقات الزراعية. وبينت نتائج الدراسة حول تفضيل نمو فطر B. bassiana على ثلاثة أوساط غدائية وهي CDA، SDA، PDA إن الوسط الغذائي SDA هو الوسط المفضل لنمو الفطر عند درجة حرارة C 27 ونسبة رطوبة 94-97%. وأظهرت نتائج كفاءة تأثير فطر B. bassiana في اصابة بعض الآفات الحشرية أن جميع العزلات التي تم الحصول عليها كانت ذات ضراوة عالية في حدوث الإمراضية وظهور الأعراض والفتك المباشر للآفات الحشرية التي استخدمت في إجراء التجارب خلال فترة زمنية بين 2-9 أيام وذلك حسب نوع الحشرة والإصابة بالفطر. وبينت نتائج هذه الدراسة أن العزلة المحلية من فطر B. bassiana كانت أكثر فعالية في مكافحة بعض الحشرات الاقتصادية مقارنة بالمستحضرات التجارية للفطر التي تم الحصول عليها من جمهورية مصر العربية ((Biover® ومن ألمانيا (Naturalis®)، حيث لوحظ أن العزلة المحلية لها تأثيرات معنوية في مكافحة آفة المن الزراعية Mysus persicae، وآفة الحبوب المخزونة سوسة الأرز oryzae Sytophilus، وقد أطلق على العزلة المحلية اسم LAM/07 والتي يمكن استخدامها في مجال المكافحة الحيوية بعد إكثارها تجاريا. Abstract The entomopathogen fungus Beauvaria bassiana (Balsamo) had been surveyed and diagnosed from 20 agroecosystem soil samples of different crops located in North West of Libya. The presence rate of the fungus varied because of the abiotc and biotic factors such as temperature, Rh, pH, crops, insect species and agricultural practices. Results indicated that B.bassiana preference to growth media CDA, SDA, PDA was significantly different. The SDA growth medium was the most preferable for B.bassiana at 27◦C and 94-97% Rh. Data revealed the high efficacy of B.bassiana on selected insect pests. All isolates were pathogenic to the selected insects used in this study. Symptoms and death of insects were observed within 2-9 days after infection, depending on the insect species and mode of infection. Results of this study indicated that the local isolate of B.bassiana was more effective to control some insects when compared with commercial formula of B.bassiana from Egypt Biover® and from Germany Naturalis®. The local isolate was effective on aphids Mysus persicae and the rice weevil Sytophilus oryzae, which showed high significant difference in the processes of infectivity and mortality rate of the insect pests with a promise of its mass production and as an agent of biological control.
