Simulation of solar powered absorption cooling system for buildings in Pakistan

Asim, Muhammad January 2016 (has links)
This research investigates the potential of a solar powered cooling system for single family houses in Pakistan. The system comprises water heating evacuated tube solar collectors, a hot water storage tank, and an absorption chiller. A literature review was carried out covering: • Energy situation, climate, and renewable energy potential in Pakistan; • Energy and thermal comfort in buildings, particularly for hot climates; • Solar collectors and solar cooling systems, particularly for hot climates; • Dynamic thermal simulation and weather data for solar energy systems and buildings. It was found that Pakistan is short of energy and that there is a great need to cool buildings. Renewable energy cooling systems are, therefore, of interest. The system described above was selected, as it was found that solar energy is abundant in Pakistan when cooling is required; thermal systems can be more economical than photovoltaics for hot climates and suitable components (collectors, absorption chillers, etc.) are commercially available. The TRNSYS dynamic thermal simulation program was selected as the main research tool, as it has been tested for solar energy and building applications by many researchers and suitable experimental facilities were not available. A simple typical building in Pakistan with a solar cooling system was simulated. Optimum values for key parameters were found by repeated simulations. It was concluded that the system would be able to provide cooling when required without an auxiliary heat source, and that an evacuated tube collector with a gross area of 12 m2, a collector flow rate of 165 kg/h, and a storage tank volume of 2 m3 would provide satisfactory performance for a 3.52 kW absorption chiller integrated with 42m3 single room. The results were in good agreement with published results from other researchers. Sensitivity analysis was carried out for the collector area, collector flow rate and storage tank size. It was found that varying the collector area had the largest effect on system performance, followed by varying the storage tank volume. Varying the collector flow rate had the smallest effect. It is recommended that solar cooling systems should be considered for Pakistan, and that further research should be carried out into reducing building cooling loads, using surplus heat for other loads, improving the performance of the proposed solar cooling system, and comparing it with other systems such as photovoltaics.

Mineral development for growth: developing a mineral policy framework and mining cadastre system for Pakistan

Ashraf, Hamid January 2017 (has links)
A thesis submitted to the Faculty of Engineering and the Built Environment, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Doctor of Philosophy. Johannesburg, 2017 / Mineral resources can act as key for economic growth and have the potential to transform economies and societies. The extent to which such transformation takes place varies depending upon the method of their use. Pakistan is gifted with significant mineral resources that have the potential to lift its economy and bring prosperity to its citizens. For this to happen, Pakistan must formulate a mineral policy based on leading practices to attract mining investment and increase the sector contribution to GDP in the range of 3 – 5%. The fundamental objective of this research is to investigate the process of mineral policy development of Pakistan against leading developing minerals-based economies and to formulate a strategic fit mineral policy framework, keeping in mind its fragile political, socio-economic and security environment. Developing countries with mineral wealth must try to gain maximum benefit from their mineral resources. These are national assets and should be managed responsibly and not used unwisely. For the gap analysis between Pakistan‘s current mineral policy framework and leading developing countries, five criteria were formulated. Two basic principles were kept in mind with the choice of countries; first, a developing country like Pakistan should be selected; and second, at least two countries should be Islamic. Eight developing courtiers, Chile, Mexico, Brazil, Peru, India, South Africa, Kazakhstan and Turkey were selected for analysis. The key elements for the mineral sector of Pakistan are; Pakistan‘s mineral sector is lacking an enabling institutional framework for efficient access to mineral resources; it lacks an enabling fiscal and regulatory framework for mining to enhance the economic attractiveness of the sector; and the absence of a mining Cadastre System to secure mineral rights prevents security of tenure. Six stakeholders, Government and its implementation bodies; Mining industry; Local communities and their representatives; Law enforcing agencies (LEA's); Religious Monarchs; and Financial institutions were identified and their role defined in policy development framework. A new mineral Policy Framework was formulated based on seven key enablers, namely; institutional framework; stable political economy; legal framework; regulatory framework; fiscal framework; stakeholder participation; and sustainable development. A new organisational structure of the Ministry is proposed based on the generally accepted organisational structure of tiers, implementation and regulatory bodies. An implementation plan based on three building blocks was developed for implementation of the new Mineral Policy Framework. Implementation of an enabling Institutional framework and other key elements of mineral policy framework were suggested to be implemented through the constitution of a Mineral Development Advisory Committee (MDAC). A PakMining Cadastre system was suggested to be constituted under the new Ministry for secure minerals rights system. System design and the geometrical architecture of the PakMining Cadastre System were also suggested. / MT 2017

Pakistan foreign policy formulation, 1947-65 : an analysis of institutional interaction between American policy making bodies and the Pakistan Army

Soherwordi, Syed Hussain Shaheed January 2010 (has links)
This thesis examines through the use of archives and oral evidence the role of the Pakistan Army in the context of Pakistan’s domestic politics and foreign policy. Its main purpose is to explore the autonomy of the Pakistan Army in shaping national and foreign policy between the years 1947-1965. Focusing on its independent relationship with three instruments of policy-making in the United States – the Department of State, the White House and the Pentagon – the thesis argues that the relationship between the Army and these policy-making bodies arose from a synergistic commonality of interests. The Americans needed a country on the periphery of the Soviet Union to contain Communism while the Pakistan Army needed US military support to check Indian regional military hegemonism in South Asia. This alliance was secured to the disadvantage of democratic political institutions of Pakistan. The Army, which became stronger as a result of US military and economic support, came progressively to dominate domestic politics. This led not only to weakened civilian governments in the period I am examining, but in 1958 to the military seizure of political control of the country itself. The infringement of the Army into civilian spheres of government further caused a deterioration in relations between East and West Pakistan. The increasing clout of a US-backed Army whose elite officers had a bias against the eastern wing of the country, the thesis argues, thus indirectly resulted in the dismemberment of Pakistan itself. To explain the Army’s ascendancy its transformation from British colonial army into a national political actor, is documented. The thesis explores the influence of the martial-race theory and of Punjabisation in the Army as it developed in the colonial era. Secondly, it reconstructs how provincial politics weakened the Federal Government and allowed the Army to usurp political power to a disproportionate degree. Thirdly, the thesis considers the extent to which the US-Army relationship influenced and even took precedence over decision-making within the government itself. It details the military pacts made between the two countries to contain the USSR in this period. Finally, it explores where and how the interests of the US and Pakistan Army diverged, in particular concerning their respective relations with India. The complications arising in Indo-Pakistan relations in consequence of an abrupt tilt of the US towards India after the Sino-Indian war in 1962 are also examined. In reaction to this new Indo-US nexus, it is argued the Pakistani military junta leaned towards China and in 1965 endeavoured to make use of it advanced, US-supplied weaponry before – as they saw it – the strategic balance was to be irrecoverably lost in favour of India. In conclusion, the thesis argues that the period under consideration saw a complete failure of the US policy of containing communism whilst at the same time avoiding war between its allies in the region, and that this had tragic consequences for the future of democracy in Pakistan.

Effectiveness of small-group sessions in enhancing students generic skills at the Shifa College of Nursing, Islamabad, Pakistan

Daredia, Afshan Saleem 12 1900 (has links)
Thesis (MPhil)--Stellenbosch University, 2013. / ENGLISH ABSTRACT: There is no dearth of evidence of the importance of facilitation for the effectiveness of small-group teaching. However, there is hardly any local literature on the knowledge of untrained facilitators and how they apply this knowledge to develop generic skills in students. Needs identified through this study have provided an insight into the areas requiring formal training that could be useful for developing nursing-faculty development programmes.

Stratigraphic and structural framework of Himalayan foothills, northern Pakistan

Pogue, Kevin R. 03 December 1993 (has links)
The oldest sedimentary and metasedimentary rocks exposed in the Himalayan foothills of Pakistan record a gradual transition seaward from the evaporites of the Salt Range Formation to pelitic sediments deposited in deeper water to the north. The Upper Proterozoic Tanawal Formation was derived from erosion of a northern highland produced during the early stages of Late Proterozoic to early Ordovician tectonism. Early Paleozoic tectonism is indicated by an angular unconformity at the base of the Paleozoic section, the intrusion of the Mansehra Granite, and the local removal of Cambrian strata. Paleozoic shallow-marine strata are preserved in half-grabens created during extensional tectonism that began during the Carboniferous and climaxed with rifting during the Permian. Paleozoic rocks were largely or completely eroded from northwest-trending highlands on the landward side of the rift shoulder. Thermal subsidence of the rifted margin resulted in transgression of the highlands and deposition of a Mesozoic section dominated by carbonates. Compressional tectonism related to the impending collision with Asia commenced in the Late Cretaceous. Rocks north of the Panjal-Khairabad fault were deformed and metamorphosed during Eocene subduction of northern India beneath the Kohistan arc terrane. Following their uplift and exhumation, rocks metamorphosed beneath Kohistan were thrust southward over unmetamorphosed rocks along the Panjal and Khairabad faults which are inferred to be connected beneath alluvium of the Haripur basin. Contrasts in stratigraphy and metamorphism on either side of the Panjal-Khairabad fault indicate that shortening on this structure exceeds that of any other fault in the foothills region. The migration of deformation towards the foreland produced south- or southeast-vergent folds and thrust faults in strata south of the Panjal-Khairabad fault and reactivated Late Cretaceous structures such as the Hissartang fault. The Hissartang fault is the westward continuation of the Nathia Gali fault, a major structure that thrusts Proterozoic rocks in the axis of a Late Paleozoic rift highland southward over Mesozoic strata. Fundamental differences in stratigraphy, metamorphism, and relative displacement preclude straightforward correlation of faults and tectonic subdivisions of the central Himalaya of India and Nepal with the northwestern Himalaya of Pakistan. / Graduation date: 1994

Child health in Pakistan: an analysis of problem structuring

Panwhar, Samina T. 26 August 2009 (has links)
This study presents an analysis of policies addressing child mortality in Pakistan focusing on problem structuring, using a comparison with Bangladesh. Pakistan's progress in addressing child mortality rate has been much slower than that of Bangladesh despite the fact that Pakistan has excelled in economic growth, and the two countries have comparable populations and share political history. This study analyzes and provides an explanation for differential outcomes in terms of problem structuring in the two countries. A comparative analysis of policy documents reviewed for the two countries illustrates the fact that Bangladesh, in formulating its child health policy, has emphasized the input factors such as nutrition and environmental aspects, besides health services. Pakistan, on the other hand, maintains a general problem formulation strategy focusing mainly on health service and ignoring the social, environmental, and other factors causing morbidity and mortality in children. Another comparison between policy formulation in each country and the extensive literature available on child mortality suggest that neither country pays as much attention to structural factors as the literature does. The analysis provides some insight into differentials in policy formulation associated with child mortality in the two countries, but more importantly, it provides an understanding of the underlying elements for inadequate policy outcomes in case of Pakistan.
