Dynamic Compression Plate: A useful procedure for sub-trochanteric femur fracture with osteopetrosis.
No full textIntroduction: Osteopetrosis is an un common disease. It is of infantile and adult type. With adult type osteopetrosis, bones are vulnerable to fracture even with minimal injury. As there is increased bone density and small medullary canal, therefore, these fractures are challenging for orthopedic surgeons.Objective: To evaluate the results of Dynamic Compression Plate (DCP) for the fixation of sub-trochanteric fractures of femur with osteopetrosis in term of union malunion, non-union and post-operative infection.Methodology: This prospective study was conducted in the department of Orthopedic surgery at Muhammad Medical College Mirpur Khas from March 2015 to February 2017. Patients, with sub-trochanteric fractures of femur having osteopetrosis, between the age of 20-60 years of either gender were included in this study. All fractures were fixed with DCP. Post-operatively patients were mobilized with crutches in 1st week, followed by partial weight bearing in 3rd week and full weight bearing in 6 weeks.Results: Union of fractures occur in 98 %patients. Mal union in one patient and nonunion in one patient. Post-operative infection was observed in one patient.Conclusion: This study shows management of sub trochanteric fractures of femur in patients with osteopetrosis are best treated with DCP with little or no complications.Key words: Osteopetrosis, sub trochanteric fractures, DCP
MERGING SPIRITUALITY AND RELIGION: DEVELOPING AN ISLAMIC LEADERSHIP THEORY
No full textLeadership has been much talked about in the literature of social sciences. Numerous theories seem to have confused researchers and therefore scattered ideas about leadership continue to emerge from time to time. These theories can be classified into behavioral studies, contingency studies, transactional studies, transformational studies, charismatic studies, and integrative studies. Very recently, researchers have introduced a new concept of leadership known as 'authentic leadership.' This author argues that Islam provides the most comprehensive understanding of leadership through its highly developed and modern ethical system that seeks guidelines from the Qur'Én and Sunnah of Prophet Muhammad [p.b.u.h]. The author also argues that grounds for leadership have already been laid by Islamic teachings several hundred years back. Nevertheless, there is a need to understand and comprehend these teachings and integrate them into a comprehensive and elaborate theoretical model of leadership theory based on Islamic perspectives. The paper first summarizes the theological beliefs and fundamental socio-economic principles of Islam and cultural setup of society based on the Qur'Én and Sunnah. It then presents a framework of Islamic Leadership Theory. The paper also discusses the theoretical and practical implications of the proposed framework. Recommendations are also made for further theoretical development of the proposed model.JEL classification: M14, M59Key words: Spirituality, Religion, Islamic leadershi

Travelogue "Butterfly Rays and Tornadoes" Intellectual Review
No full textTravel is part of human nature. He wants to get acquainted with the culture and way of life of
the place where he is traveling. The First travelogue is “Ajaibat e Farang” the author of which
is Yousaf Hussain Kambal posh. After him Sir Syed Ahmed khan, Allama Shibli Noumani and
Muhammad Hussain Azad also wrote travelogues. The twinth century remained popolur
because of travel. Travelogues of Shafiq ur Rehman, Ibn e Insha and Begum Akhtar Riaz ud
Din came to light during this period. Women travelogues Sheen Farukh, Bushra Rehman and
Parveen Atif. Parveen Atif wrote two Urdu travelogues “Kiran Titli Or Bagoly” and “Taper
Wasni”.Her travelogues are beautiful gift in intellectual terms.
 
Efficient global robust optimization of unconstrained problems affected by parametric uncertainties
No full textA novel technique for efficient global robust optimization of problems affected by parametric uncertainties is proposed. The method is especially relevant to problems that are based on expensive computer simulations. The globally robust optimal design is obtained by searching for the best worst-case cost, which involves a nested min-max optimization problem. In order to reduce the number of expensive function evaluations, we fit response surfaces using Kriging and use adapted versions of expected improvement to direct the search for the robust optimum. The numerical performance of the algorithm is compared against other techniques for min-max optimization on established test problems. The proposed approach exhibits reliable convergence, is more efficient than previous methods and shows strong scalability.Precision and Microsystems EngineeringMechanical, Maritime and Materials Engineerin
Facilitating transmuters' acquisition of data scientist knowledge based on their educational backgrounds: state-of-the-practice and challenges
No full textPurpose: In recent years, data science has become a high-demand profession, thereby attracting transmuters (individuals who want to change their profession due to industry trends) to this field. The primary purpose of this paper is to guide transmuters in becoming data scientists. Design/methodology/approach: An exploratory study was conducted to uncover the challenges faced by data scientists according to their educational backgrounds. An extensive set of responses from 31 countries was received. Findings: The results reveal that skill requirements and tool usage vary significantly with educational background. However, regardless of differences in academic background, the data scientists surveyed spend more time analyzing data than operationalizing insight. Research limitations/implications: The collected data are available to support replication in various scenarios, for example, for use as a roadmap for those with an educational background in art-related disciplines. Additional empirical studies can also be conducted specific to geographical location. Practical implications: The current work has categorized data scientists by their fields of study making it easier for universities and online academies to suggest required knowledge (courses) according to prospective students' educational background. Originality/value: The conducted study suggests the required knowledge and skills for transmuters to acquire, based on their educational background, and reports a set of motivational factors attracting them to adopt the data science field.Accepted Author ManuscriptTransport and Plannin
Mediterranean Sea Struggle between Turkey and Greece and its Implications for the Existence of NATO and the Way Forward
No full textThe Mediterranean Sea has been a vital passage since time immemorial. It was the cultural and ideological fault line between empires in eastern and western countries. Contrary to its previous past, the last century saw the peaceful sea. However, Greece and Turkey’s recent standstill ruins this ideal time. Turkey’s assertive policies to explore gas and oil in the Mediterranean Sea, known as the Blue Homeland approach, have been a significant disruption in the region’s status quo. The presence of France, Egypt, and the UAE in the dispute has exacerbated this rivalry. The negotiated conflict settlement is essential; otherwise, NATO’s very existence and regional stability are in danger. The author explains the conflict actors’ their interests and introduces the potential solution to this conflict and NATO alliance revitalization that could end Russian aggression in the region
