Since the independence of Pakistan, Karachi has emerged as a mega polis catering to the largest population in all across the country. Karachi has earned the reputation of melting pot of all ethnic shades of Pakistan. The city also serves as the financial capital of Pakistan. All banks, financial institutions, national and international organizations have their headquarters in Karachi. It also has the highest literacy rate in Pakistan. However all this was not achieved without a cost. Due to its development more and more people from all across Pakistan still want to make Karachi their destination for fulfilment of their dreams. This constant migration into the city has made it the most unmanageable city of Pakistan too. The authorities fail to provide services to its citizens on the pretext of lack of funding and incapacity. This study focuses on the issues faced by Karachi and indirectly by Pakistan due to the ever increasing ...

Yet there have been exceptions. On one hand some predominantly authoritarian regimes around the world are said to have harbored vibrant civil societies such as some countries of East Asia and Latin America. In this context, this paper overviews the growth and development of civil society in Pakistan during the rule of two military dictators in Pakistan viz. Ayub Khan (1958-1969) and Zia-ul-Haq (1977-1988) in the light of state-civil society models of conflict and coordination. It further seeks to explore: How those dictators treated the civil society in Pakistan? What was the response of civil society towards the dictatorial rule? And can we draw some parallels in the working of this nexus during the two eras?

A cable-driven robot was used to apply the external forces and an adaptive frequency oscillator scheme was developed to adapt the timing of force actuation to the gait frequency during walking. The external forces were directed in the sagittal plane to assist the trailing leg during the forward propulsion and vertical deceleration of the pelvis during the gait cycle. A pilot experiment with five healthy subjects was conducted. The results showed that the subjects applied lower ground reaction forces in the vertical and anterior-posterior directions during the late stance phase. In summary, the current work provides a novel approach to study the role of external pelvic forces in altering the walking effort. These studies can provide better understanding for designing exoskeletons and prosthetic devices to reduce the overall walking effort.
