تعتبر الاشيريكية القولونية من أكثر الممرضات البكتيرية تقلباً. سلالات من هذه البكتيريا تمتلك عوامل شراسة تمكنها من التسبب في حدوث الإمراض الاسهالية وكذلك الإصابات خارج الجهاز المعوي، عن طريق العديد من الميكانيكيات الامراضية الخاصة.الاشيريكية القولونية الممرضة معوياً Enteropathogenic Escherichia coli (EPEC) هي من أهم مجموعات الاشيريكية القولونية المسهلة والمرتبطة مع إسهال الأطفال الرضع في الدول النامية. كذلك تكمن أهمية الاشيريكية القولونية المدمية معوياً Enterohemorrhagic EHEC)) Escherichia coli في الإصابات الآدمية، في ارتباط هذه الكائنات مع نوعين من الأمراض المهمة وهي التهابات القولون المدمي وحالات البول المدمي. الهدف من هذه الدراسة هو مدى وجود سلالات الاشيريكية القولونية التابعة لمجموعتي EPECو EHEC في الأطفال وفي مصادر الأغذية والمياه في منطقة طرابلس-الجماهيرية. لاشيريكية القولونية عزلت من المصادر المختلفة شملت براز الأطفال والأغذية والمياه. أجريت الاختبارات الميكروبيولوجية لجميع العزولات واستعمل نظام API20E للتأكد من تعريف العزولات. الاختبارات المصلية عن طريق التراص على الشريحة أشارت إلى أن 132 عزولة كانت تنتمي إلي السلالات التابعة إلي مجموعتي EPEC وEHEC، وقورنت النتائج مع دراسات أخرى. تم عزل المجموعات المصلية التالية والتي تتبع EPEC وEHEC O26:، O45، O55، O86، O103 ، O111 ، O114،O119 ،O121، O125، O126، O127، O128، O142 ، O145 ، O175،O158 . نتائج اختبارات مدى حساسية العزولات للمضادات الحيوية كانت متنوعة ,وجميع العزولات كانت حساسة للمضاد الحيوي amikacin . Abstract Escherichia coli is probably the most versatile of all bacterial pathogens .Strains of this species posses combination of virulence factors that enable them to cause diarrheal diseases and also the cause of extra intestinal diseases by means of several distinct pathogenic mechanisms .Enteropathogenic Escherichia coli ( EPEC) is an important categories of diarrheagenic E.coli which has been linked with infant diarrhea in developing world .The importance of Enterohemorrhagic Escherichia coli (EHEC) in human diseases lies in the association between these organisms and two diseases, hemorrhagic colitis (HC) and hemolytic uremic syndrome (HUS) . The aim of this study was to detect the presence of EPEC and EHEC in children and in foods and water sources in Tripoli –Jamahiriya.E.coli was isolated from all sources. Full microbiological studies were performed on all isolates, and API20E system was used to confirm their identification .Serological studies by slide agglutination showed 132 isolates were belong to EPEC and EHEC serogroups .The following serogroups were isolated : O26,O45,O86,O55, O103,O111,O114,O119,O121,O125,O126, O127,O128,O142,O145, O157 and O158The results were compared with those of other investigators.Results of antibiotics sensitivity were variable and all of isolates were sensitive for one antibiotic amikacin .

Abstract Libyan cities have experienced a period of rapid urban expansion in the past decades. Urban growth as an example has been the focus of urban researches for a long time. Due to the complexity of the urban growth process, it’s very difficult to model urban growth using traditional urban models. Recently, urban researches are keen on a new technology, Remote Sensing. Remote Sensing technique was applied in many aspects of life, due to ability of covering and representing the real world around us. In urban research, field researches set up many applications to simulate the urban phenomena such as sprawl process, landuse change trends, landcover...etc. Remote sensing technology helps to extract and organize the data about such phenomenon. In addition to understand their spatial relationships, and provides a powerful means to planners and decision makers for analyzing and information about a place or a phenomenon. This will have great impact on the quality of the decision-making. The study uses Spot 5 images, topographic maps which derived from aerial photographs for the year 1980. The remote sensing image interpretation and change detection to review the urban expansion for the study area in (1980 and 2009).Spot satellite image of 2009 and Landuse maps1980 will be used to derive information on urban land use in the study area. The visual interpretation is used to extract landuse. The mutual use of Remote Sensing (RS) and Geographic Information System (GIS) describes the overall physics changes of the study area. This effort can be considered as an application case in this field (RS-based town planning information system), where this thesis show how that system can be useful of using this technology and supporting the sector by developing a model that can support the process of planning and maintain what remained of the agricultural lands to prevent them from encroachment by the urban growth.

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.
