A case study validation of the Pair-estimation technique in effort estimation of mobile app development using agile processes
No full textIn the software development process, effort estimation is essential and a critical phase for the development team in order to ensure that development tasks will be delivered within the planned time. This paper presents a confirmatory case study in an IT company, which examined its current estimation techniques and its process in the context of mobile app development in the Agile process. Moreover, the study provides, and has validated, a proposed estimation technique, namely Pair-estimation, in order to enhance the accuracy of the existing technique. This study, in addition, presents the effectiveness of estimation factors/predictors in supporting the development team to manage, estimate and create subtasks for their user stories

Qur’anic Scholarships in Post-Colonial Lagos: A Study of Contributions of Shaykh Adam ‘Abdullah al-Ilory (1917-1992)
Get PDFIslam, perhaps hardly been found in any area without existing of Islamic education and Lagos was no exception. Therefore, the advent of Islam in Lagos has resulted to the spread of Arabic-Islamic education everywhere. The Qur’anic education, which is the essential part of Islam started immediately by an informal method. Later, during the Post-Colonial era, the Qur’anic education witnessed tremendous development and growth by of one the often-acclaimed greatest Islamic scholars called Shaykh Adam Abdullah al-Ilory, who situated his Arabic school; Arabic and Islamic Training in Agege area of Lagos, as Quranic Center. So, it is the interest of this paper to assess his contributions to the Qur’anic scholarship, highlights some challenges and provides useful suggestions for the improvement. The research adopted descriptive and historical methods, which assist in presenting a comprehensive x-ray of his contributions to the Qur’anic education in Islam and Lagos society in particular

Autoamputation of diabetic toe with dry gangrene: a myth or a fact?
No full textAbdullah Al Wahbi Division of Vascular Surgery, King Abdulaziz Medical City, Riyadh, Saudi Arabia Abstract: Diabetes is associated with various complications and reduced quality of life. Of the many complications, some are life-threatening. Among these, foot complications remain an important concern. The major foot complications include foot ulceration, cellulitis, abscess, wet gangrene, dry gangrene, and necrotizing fasciitis, with different pathophysiological concepts behind each of them. Gangrene occurs due to reduced blood supply in the body tissues that leads to necrosis. This condition may arise because of an injury, infection, or other health conditions, majorly diabetes. Gangrene is classified as dry, wet, and gas gangrene. In case of wet and gas gangrene, surgical amputation is usually performed to prevent the spread of infection to other tissues. In dry gangrene, due to the presence of clear demarcation, autoamputation is preferred in certain parts of the globe. The present review aims to analyze the mode of dry gangrene management in diabetic patients based on previous evidence and plans to highlight various management strategies available for dry gangrene and the advantages/disadvantages of different treatments with special consideration to autoamputation.
