Why The Green Revolution Was Short Run Phenomena In The Development Process Of Pakistan: A Lesson For Future

Agriculture is the most important sector of Pakistan’s economy. It provides food and fibre, source of scarce foreign exchange earning and a market for industrial goods. In 1960s various policy measures were taken for Agriculture development. The research tries to examine various issues related to this sector. Focus of the research, however, is to analyze the role of Green Revolution in the development process of Pakistan and its short and long term impact on the economy. The paper analyzes weaknesses due to which the Green Revolution remained a shortterm phenomena. The contributing factors of Green Revolution and other supporting institutions are also discussed. The findings of this study show that the Green Revolution increased agriculture production and employment level. It also had impact on distribution of income and the social and political environment in the country. However, there were certain policy gaps due to which the impact of Green Revolution remained a short-term phenomena.

General physicians\u27 perspective of sleep apnea from a developing country

To assess the knowledge of general physicians about the diagnosis and management of obstructive sleep apnea (OSA), a self-administered questionnaire, containing 15 questions, was distributed to 160 doctors attending a pulmonary CME program in March 2002. After 15 minutes of response time, the questionnaires were collected. The data were entered and analyzed using SPSS (Version 10.0) software. One hundred and twenty (75%) questionnaires were returned. Only 41% of responders had ever read an article about OSA and 36% had suspected it at least once in their practice. The majority (61-77%) of responders were aware of the common symptoms of OSA, but 55% did not recognize its association with hypertension. A significant number of doctors were not aware that OSA could occur in non-obese individuals (33%), women (42%) and children (39%). Only 25% of responders recognized that a history and blood tests were insufficient to make a reliable diagnosis of OSA. Half of the responders were aware of CPAP therapy for OSA, whereas 18% would have prescribed sedatives to treat sleep disturbances in OSA

Multiscale Damage Modelling of Notched and Un-Notched 3D Woven Composites With Randomly Distributed Manufacturing Defects

This work proposes a stochastic multiscale computational framework for damage modelling in 3D woven composite laminates, by considering the random distribution of manufacturing-induced imperfections. The proposed method is demonstrated to be accurate, while being simple to implement and requiring modest computational resources. In this approach, a limited number of cross-sectional views obtained from micro-computed tomography (µCT) are used to obtain the stochastic distribution of two key manufacturing-induced defects, namely waviness and voids. This distribution is fed into a multiscale progressive damage model to predict the damage response of three-dimensional (3D) orthogonal woven composites. The accuracy of the proposed model was demonstrated by performing a series of finite element simulations of the un-notched and notched tensile tests (having two different hole sizes) for resin-infused thermoplastic (Elium®) 3D woven composites. Excellent correlation was achieved between experiments and the stochastic finite element simulations. This demonstrates the effectiveness of the proposed stochastic multiscale model. The model successfully captured the stochastic nature of tensile responses (ultimate tensile strength and stiffness), damage modes (matrix damage and fibre failure), and initiation and propagation of transverse cracks in thermoplastic 3D woven composites, consistent with experimental observation. The stochastic computational framework presented in this paper can be used to guide the design and optimization of 3D textile composite structures
