Item Restricted A calculation of Geodesics in fuzzy flat Robertson-Walker space and its folding(Saudi Digital Library) Asma Salem Al-LuhaybiThis thesis introduces and study new types of geodesics of flat RobertsonWalker space. Types of the retractions, deformation retracts and foldings of flat Robertson-Walker space are presented. The relations between new types of the geodesics, foldings and the deformation retracts of submanifolds of flat Robertson-Walker space are deduced. Also, the isometric and topological folding in each case and the relation between the deformation retracts after and before folding have been obtained. The con4 0Item Restricted A Standard-based Evaluation of AL-Madinah In-service EFLTeachers Knowledge, and it،s Correlation with their performance(Saudi Digital Library) Mona Saad AL-OsaimiThe present study is an investigative study which aimed at assessing the current level of teaching knowledge background of secondary stage female EFL teachers in Al-Madinah, and finding out if there is a correlation between these teachers' teaching knowledge background level and their teaching performance level.

Trichoderma viride was the most dominant species (35% of the total count) followed by genus Fusarium comprised of (30% of the total count) F. poae, F. bulbigenum var.lycopersici, F. moniliform and F. chlamydosporum. The other species were Chaetomium globosum (15% of th0 0Item Restricted An active trust-region algorithm for solving constrained optimization problem(Saudi Digital Library) Samira Mala Faize El-GohnyThe thesis is planned to work in the area of numerical analysis. More precisely in the further development of numerical methods for solving general nonlinear programming problems. The quadratic penalty function is also used as a merit function to decide whether the trial step should be accepted. The convergence theory of this algorithms is based on the fraction of cauchy conditions. In this algorithm the dogleg method will be used to compute the trial step.0 0Item Restricted An Exploration of EFL Students learning styles and perceptions of vocabulary development in self-directed mobile-based applications(Saudi Digital Library) Budor Omar Al-ahmadiThis descriptive and correlative study investigated (a) the visual and auditory styles of Saudi female EFL students at Taibah University while using self-directed mobile learning vocabulary applications and the relationship between them; (b) their perceptions of vocabulary development regarding recognizing vocabulary meaning, grammatical use in sentences, pronunciation and spelling; and (c) the relationship between their learning styles and their perceptions of vocabulary development while4 0Item Restricted Antimicrobial Substances in Cows and Sheeps(Saudi Digital Library) Abrar Abdul Rahman AlsharifThe antimicrobial of cow and sheep urines studied against harmful microbes isolated and identified in the King Fahd Hospital (Madinah) include; Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus and Candida albicans, and some harful fungi (Fusarium, Aspergillus niger and Alternaria).The agar well and disc diffusion methods were used . successive attempts in this research to find the best preparation for urines to show its antimicrobial agent start from fresh u4 0Item Restricted Appoximating fixed points iteration(Saudi Digital Library) Habes Eid Shati Al-SommerIn this thesis we will introduce a three step iterative scheme with errors and prove convergence of the scheme to a common fixec point of asymptototically quasi-nonexpansive type nonself mapping in Banach spaces. We also present an iterative scheme with errors for a finite family of asymptotically quasi-nonexpanssive mapping and prove some strong convergence results. Our results improve and generalize a number of convergence theorems existing in the literature.5 0Item Restricted Derivations in prime rings(Saudi Digital Library) Afnan Musa Al-JuhaniIn this project, we study derivations and Jordan derivations in prime rings. We present a well-know result given by E. Posner about the composition of derivations. Also a relationship between commutativity of a ring and the existence of a non-zero derivation is presented. Finally, we present a well-know result by I. Herstein which states that every Jordan derivation on a prime ring of characteristic not equal to 2 is a derivation7 0Item Restricted Diversity of polycyclic aromatic hydrocarbons -degrading bacteria and corresponding marker genes in petroleum oil contaminated soils in Almadinah Almunwarah, KSA(Saudi Digital Library) Amal Abdullah FraidiPolycyclic Aromatic Hydrocarbons (PAHs) represent a serious source of hazard due to its deleterious health effects. Soil contamination with petroleum derivatives including PAHs is an increasing problem in the Kingdom of Saudi Arabia and other parts of the world. The main aim of this project was to define some catabolic gene markers for degradation of certain PAHs by bacteria in contaminated soils collected from Almadinah Almunwarah. Molecular biology techniques were used as an alternative a6 0Item Restricted EFL Teachers’ Attitudes towards Group Work in EFL Classrooms(Saudi Digital Library) Anwar Faisal AlarfajThe aim of this study was to investigate EFL teachers’ attitudes towards using group work in English language classrooms.
