The development of intelligent data analysis techniques for fraud detection can be well motivated from an economic point of view. Following the definition of fraud, it is easy to state the losses caused by fraud as primary motivation for fraud detection mechanism. Fraud in communication networks can be described and characterized as determined unobserved intentions to illegitimately use the communication networks in order to avoid service charges or gain unjust advantage. Efforts in this work are directed at fraud detection in post-paid organizational mobile communications networks. Two different complementary approaches are used: (differential and absolute, user profiling and classification approaches). It is observed that fraudulent intentions are reflected in the observed call data, which was subsequently used in describing behavioural patterns of users. Relevant user groups based on call data were identified and users are assigned to a relevant group to model the fraud detection mechanism. In the task the call data was used to learn models of calling behaviour so that these models make inferences about users’ intentions. From the analysis and model detectability experiment carried out in this scientific research work. It was discovered that the model detects over 89% of the fraudsters in the testing set (i.e fraud with certainty factor of 0.89). With the bias proportion of 0.0 and Mean Absolute Error (MAE) of (2.71) generated in the fraud detection. The model of course shows a good performance.

Organic agriculture, as an adaptation strategy to climate change, is a concrete and promising option for rural communities and has additional potential as a mitigation strategy. The management of soil organic matter is critical to maintain a sustainable productive organic farming system. They possess many desirable soil properties and exert beneficial effect on the soil physical, chemical and biological characteristics as well as a sink for carbon dioxide sequestration to mitigate the negative impacts of climate changes. In this regard, a field experiment was carried out in a private sandy soil farm in Manshyet El Gammal, Tamiah, Fayum. Egypt to evaluate the effect of mineral and organic fertilizer treatments on growth and some chemical constituent of Jatropha curcas L. The results revealed that there were significantly differences between the fertilization treatment with superiority to the treatment T11 (50% Mineral fertilizer dose + 50% Chicken manures dose + Inoculation with cerialene) which produced the highest values for all the studied vegetative growth parameters as well as photosynthetic pigments content (chlorophyll a, b and carotenoids) and macronutrients contents (nitrogen, phosphorus and potassium).

Nowadays security has always been an important issue in the business world to ensure the integrity of content and transactions, to maintain confidentiality and privacy, and to make sure information is disseminated appropriately. But while dealing with contents encoded in XML, the hierarchical tree structured data have different confidentiality and integrity for different portions of the same content. Thus need dissemination approach specifically tailored to XML that addresses the issues of efficiency and scalability must however be provided by assuring at the same time security of contents and privacy of the parties acquiring and disseminating contents. The main objective is to provide solution to above problem using structural properties of tree based data model (such as XML document) and Document Object Model (DOM). This approach is based on notion of Encrypted Post Order Numbers (EPON) which is based on tree traversals and is defined using a random notation of such traversal number. It facilitates efficient dissemination of selected portion of content. By using structure based routing (SBR) scheme that prevents information leakage and assures that delivered content to user according to access control policies. The structure based routing framework facilitates the dissemination of contents with varying degrees of confidentiality and integrity in a network.

Industrial education considers the major and strong pillar for expecting education a renaissance to developed and activate new Egypt renaissance after the great revolution on the twenty fifth of January this renaissance will be developed To work on the development and activation anew generation of skilled and trained cadres of human to support factories and supplying elements who posses expertise craft and scientific culture and this is very important as the presence of skilled. Manufacturer basically and integrative with existing of factories and skilled engineer they are two sides of the same coin through them we can achieve leadership and industry progress. The role of the engineer is the design and the role of the specialist of industrial education Is to implement this design on the ground practically. In addition to training staff and to work up elevation their industrial culture and this role is so vital and important for the industrial development. As the specialist of industrial education's functions is teaching, practical and theoretical train for students of industrial secondary schools. As well as the super intermediate of industrial institutes to provide who is suitable to work in factories and job training in all fields. The specialist of industrial education has to work on the training and super vision of training institutions position on the level of the republic to activate its role and revitalization for the provision of train labor and also scientifically and practically qualified the prominent examples of the industrial renaissance are existing in countries like china and India recently these countries joined the G20. The big industrialized countries have moved to set up branches for them in these countries because of the abundance of skilled and trained labor and also cheap labor. At the same time the integration which has been referred to previously.

Urachal cyst is one of a spectrum of urachal abnormalities most commonly found in children. But it is a rare pathologic disease entity in the adult, which may present only with abdominal pain. We describe a case of a 49 year old male who presented with abdominal pain, fever and dysuria. Diagnosis of an infected urachal cyst was confirmed on Computed tomography of the pelvis. He was treated initially with broad spectrum antibiotics in order to allow sepsis to resolve prior to surgical excision of the cyst and fibrous tract. Histology of the excised specimen showed chronic inflammation with no evidence of malignancy. Postoperative recovery was uneventful. Urachal abnormalities are rare in adults. Clinical presentation is non-specific and must be considered as a rare differential for abdominal pain, when diagnosed, surgical excision is advised because of the risk of malignant transformation.

The repeated column chromatography of the methanol extract leads to the isolation of compound (1), which was identified as 7, 8-Dihydroxy-2H-chromen-2-one (Daphnetin) for the first time from this species. The structure of the compound was elucidated on the basis of 1H, 13C, MS etc spectral techniques. HPLC analysis method was developed for the detection and confirmation of daphnetin in the methanol extract of Daphne oleoides, which clearly determined its presence in the extract (Chromatographic Finger print) after the calibration with isolated Daphnetin. Keywords: Coumarins, Daphne oleoides, Thymelaceae, HPLC, Daphnetin.

Thryonomys swinderianus is one of two species of cane rats. This study concerned the evaluation of the lipid profiles of T. swinderianus skin, muscle and liver. SFA (% total fatty acid) was 39.5 (muscle), 41.5 (liver) and 42.4 (skin). MUFA ranged as follows (%): 10.5 (muscle), 14.0 (liver) and 21.0 (skin). The n-6 + n-3 (PUFA) (%) of 49.9 (muscle), 44.4 (liver) and 36.5 (skin) were recorded. MUFA +PUFA predominated in all the samples having (% total fatty acid) 60.4 (muscle), 58.4 (liver) and 57.5 (skin) with respective PUFA/SFA values of 1.26, 1.07 and 0.86. The n-6: n-3 range of 50.0:1 (muscle), 83.2:1 (liver) and 15.1:1 (skin) are in unhealthy ratios. The samples would supply the following values as food source (g/kg): highest in SFA (C18:0) 0.0383 (muscle), 8.43 (skin) but C16:0 in liver (7.84) whilst highest in PUFA (C18:2n-6, trans) 5.41 (skin), 5.29 (skin) but C22:6n-3, cis in muscle (0.0185). The cholesterol level in (g/kg): skin (10.5) and liver (10.5). The highest phospholipid in the samples was phosphatidylcholine. Significant differences existed in skin/muscle, muscle/liver and skin/liver in their fatty acids as well as skin /liver in phospholipids and sterols at r = 0.05.
