Effects of variable resistance on smart structures of cubic reconnaissance satellites in various thermal and frequency shocking conditions
Piezoelectric materials are widely used as smart structures in cubic reconnaissance satellites because of their sensing, actuating, and energy-harvesting abilities. In this study, an analytical model is developed in specific mechanical thermal shocking conditions. A special circuit and apparatus is designed for experimentation on the basis of the inverse piezoelectric effect. An equivalent circuit method is used to establish the relationship between the resistance and peak-to-peak voltage of lead zirconate titanate used as smart materials for cubic reconnaissance satellites. Various frequencies and resistance were applied in different mechanical thermal shocking conditions. Moreover, numerical simulations are conducted in various mechanical loading conditions to determine the accumulative effect. The model provides a novel mechanism to characterize the smart structures in cubic reconnaissance satellites. A rise in temperature increases peak-to-peak voltage; a rise in frequency decreases peak-to-peak voltage; and intensified resistance decreases peak-to-peak voltage. Based on experimentation and simulation, the optimum resistance is predicted for the various frequencies and temperatures. The various conditions may correspond to the different applications of smart structures for cubic reconnaissance satellites. The analytical calculations are in good agreement with experimental and numerical calculations. © 2017, The Korean Society of Mechanical Engineers and Springer-Verlag GmbH Germany
A Model; Road Map to Achieve Sustainable Development Goals 2030 Realizing Your Potential a Proposed Guidelines for National Health Policy for Integrated Health Care Delivery
The goals that are set for 2030 regarding sustainable Development are a wakeup call to action that reforms should be made to end poverty, protect the planet and ensure health for all and everywhere. The needs to review and reprioritize the use of existing resources in the health sector along with significant addition and allocation of resources for health should be focusing more on primary health care. Pakistan must also adopt a holistic integrated approach that views health, education, and other social sector development as intrinsically interrelated and interwoven.Most of the patients in Pakistan visit two to three general practitioner / family physicians to rule out and to know the exact diagnosis of their ailment. This increases the frequency of visits to the other physicians and decreases follow up and compliance concerning to the treatment provided. Another Important concern is record maintenance as most of the time patient loss their important notes/ reports.
So to streamline these all patient record as well as provision of safe treatment and referral if any needed in the region he is residing are the main purpose; this will decrease patient load to Private as well as public sector health units and will decrease the unnecessary movement of patients. The Unique Model by Using the latest Technology has evolved by putting the Communication, Coordination in a synchronization pattern and by keeping the health care provider and client in a centralized position.

A Viewpoint on Clinical Approach towards Assessment of Chronic Shoulder Pain
The shoulder joint offers a wide range of motion and therefore pathologies leading to restriction of its movements affect the routinely performed activities. Symptoms of the shoulder pathologies are often overlapping and usually are not specific to certain pathology. However, as discussed in this manuscript, with a targeted history, still a diagnostic algorithm can be made which can then be further guided by related clinical examination and appropriate investigations to conclude a diagnosis.

Thermodynamical Analysis of the Flow and Heat Transfer over a Static and a Moving Wedge
The first and second law characteristics of fluid flow and heat transfer over a static and a moving wedge are investigated. With the help of suitable similarity transformations, the governing boundary layer equations for the velocity and temperature fields are transformed into ordinary differential equations and are solved numerically. The velocity and the temperature profiles are obtained for various parameters and are utilized to compute the entropy generation number Ns and the Bejan number Be. The effects of various physical parameters on the entropy generation number and the Bejan number are depicted through graphs and are discussed qualitatively. It is observed that the entropy production rate is less in case of wedge moving in the opposite direction to flow as compared to static wedge.</jats:p
Sustainable Development of Chitral: A CPEC Perspective
The vision of sustainable growth of any community or region cannot be materialized unless provided with equitable socio-economic opportunities with environmentally friendly conditions. In the mountains of Hindukush, Chitral has remained significantly important from a geographic and strategic perspective. The piece of land in the extreme north of Pakistan is blessed with numerous natural resources and it is also a gateway to Central Asia. This valley is surrounded by rugged mountains, due to neglect and lack of land connection with the main country it has been deprived of the required development. The construction of the China Pakistan Economic Corridor (CPEC), an alternative passage through Chitral will bring economic opportunities through investment in different sectors. With the materialization of the CPEC route, the potential in the valley will be explored and utilized for the betterment of the country in the broader spectrum and the local economy will strengthen as well. The opening of this trade route will not only change the economic landscape of the valley but will change the sociology of the area. This mega venture along with economic opportunities will also generate challenges for the indigenous community. Expected opportunities will attract more businessmen and investors from outside. This migration process will open the door to social transformation along with challenges not only from an economic perspective but an indigenous cultural heritage of the society will be endangered. Only an inclusive and integrated development stratagem with the involvement and support of all stakeholders will lead to the sustainable economic growth of the valley. Further, the people-centric development approach will bring economic opportunities for the people, otherwise, there will be more challenges than opportunities. This research work has been conducted to investigate the expected challenges threatening sustainable growth of the community and region. Furthermore, it suggests policy guidelines based on empirical evidence for curtailing those challenges.
