Oil Film Dynamics in Aero Engine Bearing Chambers
Aero engine bearing chambers are complex machine elements inside the engines, supporting up to three concentric shafts on bearings. For safety reasons, the aero engines always employ rolling-element type bearings and therefore require a sufficient oil supply for lubrication in order to guarantee a reliable operation. As a consequence, a complex two-phase flow consisting of oil and sealing air governs the bearing chambers. A highly dynamic oil film, flowing along the chamber walls, plays a vital role to fulfill the tasks of cooling, lubricating and cleaning the bearing chambers. The design and optimization process of the bearing chambers requires a detailed understanding in order to accuratel...
Pakistan Occupied Kashmir
This book is a result of research undertaken on the subject by the scholars associated with the IDSA project on Pakistan Occupied Kashmir (PoK) - also known as Pakistan Occupied Jammu and Kashmir (PoJK) - which includes both the so-called "Azad Jammu and Kashmir (AJK)" and Gilgit-Baltistan (GB). This was legally a part of the erstwhile princely state of Jammu and Kashmir, which acceded to India in October 1947. The authors of this book seek to provide a critical analysis of the politics of the above mentioned two regions within PoK; throw light on the genesis and evolution of various political parties and interest groups, and acquaint the readers with different personalities playing important role in politics therein. The main aim of the publication is to help the scholars, analysts, and policy-makers to understand the dynamics of the political systems in PoK, the complex interaction of these systems with the government in Islamabad and the responses of the local leadership to Pakistan's strategy of keeping them under strict control in the name of representative governance over the last 70 years.

The Idea of Pakistan
In recent years Pakistan has emerged as a strategic player on the world stage—both as a potential rogue state armed with nuclear weapons and as an American ally in the war against terrorism. But our understanding of this country is superficial. To probe beyond the headlines, Stephen Cohen, author of the prize-winning India: Emerging Power, offers a panoramic portrait of this complex country—from its origins as a homeland for Indian Muslims to a militarydominated state that has experienced uneven economic growth, political chaos, sectarian violence, and several nuclear crises with its much larger neighbor, India. Pakistan's future is uncertain. Can it fulfill its promise of joining the community of nations as a moderate Islamic state, at peace with its neighbors, or could it dissolve completely into a failed state, spewing out terrorists and nuclear weapons in several directions? The Idea of Pakistan will be an essential tool for understanding this critically important country.

This is a biography of one of the greatest Caliphs of the Islamic epoch.The well known author Moin Qazi describes the vast range of his noble qualitiesIn the seventh century, the envoy of the Roman Emperor set out for Medinah, accompanied by a large entourage, flaunting the pageantry of adornments for which the Roman Empire was famous.

He was amazed and prompted by a curious emotional thought. He hinted to the Arab commoner, “What do you mean by a palace?” retorted the Arab.” I mean t...
The Arabian Seas: Biodiversity, Environmental Challenges and Conservation Measures
The Arabian Seas Marine Region encompasses marine areas from Djibouti to Pakistan, including the northern part of Somalia, the Red Sea, the Arabian/Persian Gulf, and parts of the Arabian Sea. Human pressures on the coastal and marine environments are evident throughout the region, and have resulted in harmful environmental effects. Oil and domestic, urban and industrial pollutants in several areas of this part of the world have caused local habitat degradation, eutrophication and algal blooms. Further, coastal landfill, dredging, and sedimentation, as well as nutrient and sediment runoff from phosphate mining, agriculture and grazing, and reduction in freshwater seepage due to groundwater ex...
