Infrastructure migration from datacenter to cloud Solution
No full textThe manual installation and configuration of IT systems has been a tiring and time consuming process that created huge challenges to engineers during the maintenance and management process of the IT systems. The introduction of cloud computing in combination with the rise of the virtualization technology have managed to address some of these challenges. However, these virtualized cloud systems are followed by a huge collection of new tools and platforms that are difficult to learn and maintain. As a result, Ymagis organization are investigating a way to migrate their servicesdatacenter resources into a new virtualized and effective system using a good managed platform to meet the standards and serve the constantly increasing demand of the industry The literature study of this research focuses on the concepts being discussed in testing phase. The management platform used which is vmware vCloud Director which works over vSphere resources. Based on the knowledge acquired from the literature study,a reference architecture of the infrastructure and the network layer of a generic system was proposed that describes the interconnections between the different softwared components. Furthermore, in the thesis a complete explanation of the migration process in terms of provisioning resources and managing with monitoring virtual machines inside the company virtual datacenter. The validation of the design, which was performed by conducting interviews with industry experts arriving to a proof of concept related to the work done. The validation results showed that the current methodology used can improve the scalability, upgrade ability and documentation in terms of migration of infrastructure into a cloud solution

Efficacy of electromyography and nerve conduction velocity monitoring in surgical management of terminal lipoma in children
No full textBackground: the prognosis of Terminal lipomas is better than that of other sites and pathology especially their management nowadays became clearer with better surgical outcome due to advancement of surgical tools and neurophysiology study. Objective: to assess the outcome of excision of terminal lipomyelomeningocele and reconstruction of the neural tube. Methods: From 2002 to 2016, 32 cases of terminal lipomyelomeningocele in Mansoura university hospital, insurance hospital and El Ahrar specialized center, the age of the cases ranged between 10 days and 4,3 years underwent surgical management of total or near-total lipoma excision and neural tube reformation with minimum follow up of 6 months. Results: according to system which applied to show the success of the operations, Of the 32 patients, 9 cases represent (28.1%) showed total excision of the lipoma; 17 patients represent (53.1%) had 25 mm3 of lipoma or less and 6 patients represent (18.75%) had 26 mm3 of fat or more. The neurological and urological complications was about 25%, while other complications like cerebrospinal fluid leak, wound disruption and infection was 9.4%. The surgical morbidity was comparable with the published papers. Conclusion: the excision of terminal lipomyelomeningocele and recreation of the neural tube by monitoring throughout EMG & NCV with low surgical morbidity and better results than leaving them without management or surgical interference without neurophysiological monitoring.Key words: terminal lipomyelomeningocele, lipoma, Reconstruction of neural placode. Abbreviations: DREZ, dorsal root entry zone; MRI, magnetic resonance imaging, CSF, cerebrospinal fluid
