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.

Algebraic Proof of Kalton Representation Theorems

في هذا البحث ناقشنا بعض المفاهيم ومنها وصلنا إلى مفهوم دالة التمثيل الخطي المحدودة بين جبران بوليان وأخيرا أثبتنا جبريا نظريتا كالتن للتمثيل الخطي المحدود بالأبواب التالية: الباب الأول: قدمنا في هذا الباب بعض التعريفات والقواعد والنتائج الأساسية التي نحتاجها لاحقا. مثل نظرية المجموعات ومجموعة كانتور ومجموعات بوريل. الباب الثاني: ناقشنا في الباب الثاني بعض المفاهيم المتعلقة بالجبر البولي والمؤثر الخطي المحدود بين جبران بوليان. الباب الثالث: أما الباب الثالث فقد ناقشنا فيه المفاهيم المتعلقة بالقياس والقياس المؤشروالمجموعات القابلة للقياس والدوال المقيسة والتكامل بالنسبة للقياس المؤشر وأخيرا عرفنا فضاء . الباب الرابع: قدمنا النتيجة الأساسية لهذا البحث وهي الإثبات جبريا نظريتا كالتن للتمثيل الخطي المحدود. Abstract In this thesis, we give an algebraic proof of the Kalton representation theorems. In chapter one, we give some basic standard definitions and some results we need later. In chapter two we discuss the concept of Boolean algebra, and bounded linear operators between two Boolean algebras. In chapter three, we discuss the concepts of measure, signed measure, measurable sets, measurable functions, integration with respect to signed measure; later in this chapter, we define.In the last chapter (4) we give the main result of our thesis which is the proof of KALTON representation theorems.

Sedimentological Aspects of the Sarir Sandstone in Messla Oil Field, Southeastern Sirt Basin, Libya

Abstract The Sarir Sandstone in Messla Oil Field are of Lower Cretaceous ageAptian Alpian and occur in the subsurface of the eastern part of the Messla high in the southeast Sirt Basin. The Sarir Sandstone interpret as fluvial and alluvial fan deposits whereas the Lower Sarir Sandstone were deposited in a braided system as inter-channel bars. The Upper Sarir Sandstone were deposited in the meandering belt of the fluvial system. The Sarir Sandstone is on-lapping Formation and wedge out against Rakb Group. The Sarir Sandstone is unconformable overlies the Pre-Cambrian Basement and unconformable overlain by the Upper-Cretaceous Rakb Group where it is pinching (wedging) out against the Bald Basement; Messla High)). Lithostratigraphic correlations of borehole logs ((well logs)) in concession 65 suggests that deposits gradually downed a fault controlled topographic surface increased in thickness on the down-thrown side of a fault controlled the topographic surface of Pre-Upper Cretaceous Unconformity. IV M. Sc. Hassin Haweel “Sedimentological Aspects of the Sarir Sandstone in Messla Oil Field”, 2015 Core Samples record mainly sandstone units interbedded with sandstone and shale and minor streaks and the Red Shale Unit. Estimation of depositional environment has thus been made from grain size analyses using thin sections. Petrographic studies show that the Sarir Sandstone in composition from (subarkose to arkosic arenite). The Sandstones range from texturally immature to submature, however, much of the clay content is diagenetic in origin and not a function of the depositional regime. Diagenetic studies reveal a gnite complex paragenesis. During early diagenesis, the Sarir Sandstones were modified by Calcite, dolomite, and locally pyrite, diagenesis process; replacements of corroded silica by carbonates. Cementation fluvial sandstones Intrastratal dissolution and precipitation of kaolinite in the resulting pore space. Deformation of micas between more resistant grainy pre-dates one phase of quartz overgrowth, probably the carbonates.The purpose of this study was to investigate in detail the characteristics of the Sarir Sandstone in Messla Oil Field. Another aim was to find out the relation to the adjacent area. The method of this study was conducted with the review of the previousworks in Messla Oil Field; published papers, the open file of the Arabian Gulf Oil Company (AGOCO), well files for the data to be used in constructing maps, cross sections and profiles. Four cored wells (418 feet) V M. Sc. Hassin Haweel “Sedimentological Aspects of the Sarir Sandstone in Messla Oil Field”, 2015 were used for the core descriptions and cut samples that represent the Sarir Sandstone and (130) thin sections were used for the Petrographic analysis with polarized and scanning electron microscopes (SEM). On the other hand, XRD and XRF were not available. The results of the study were: Subsurface investigations including cores (conventional and side walls), petrographic analysis, and wire-line logs suggested that this formation (Sarir Sandstone) can be divided in to three main units in Messla Oil Field; these units are: The Lower Sarir Sandstone, the Red Shale, and the Upper Sarir Sandstone. In the adjacent area Sarir Formation was divided in to five members; Pre-Upper Cretaceous Member-1 unconformably overlying Pre-Cambrian Basement, and upwards; Member 2, Member 3, Member 4, and Member 5 unconformably overlain by Rakb Group. The Lower Sarir Sandstone in Messla Oil Field is characterized by the presence of gravely sandstone, gradually changes in to the Red Shale. Also, from the core descriptions plotted sheets, and the well logs it is finning upwards. The quarzitic sandstones of (the Lower and the Upper Sarir Sandstones) are considered to be the main producing horizons where quartz grains have undergone a complex diagenetic history, including: Authigenesis, quartz and feldspar overgrowths, dissolution, carbonates cementation, and replacement. The principal conclusion was that: the gravelly sandstone unit at the Lower part of the Lower Sarir Sandstone was deposited, most likely in a braided system as inter-channel bars. The sandstone unit of the Upper Sarir VI M. Sc. Hassin Haweel “Sedimentological Aspects of the Sarir Sandstone in Messla Oil Field”, 2015 Sandstone was deposited in the meandering belt of the fluvial system. The shale facies of the Red Shale unit represents a well-developed break between the Lower Sarir Sandstone and Upper Sarir Sandstone units; it also provides a good seal for the underlying sandstone of the Lower Sarir Sandstone. The nature of the shale facies, (i.e. lack of organic content, and presence of oxidizing conditions indicated by iron oxides color, indicate that they are not a significant source of hydrocarbons. On the other hand, the Rakb Shale isthe only source rock in the studied and adjacent areas.
