This collection presents the papers presented in the symposium on extraction of rare metals as well as rare extraction processing techniques used in metal production. Paper topics include the extraction and processing of elements like antimony, arsenic, calcium, chromium, hafnium, gold, indium, lithium, molybdenum, niobium, rare earth metals, rhenium, scandium, selenium, silver, strontium, tantalum, tellurium, tin, tungsten, vanadium, and zirconium. Rare processing techniques presented include bio leaching, molecular recognition technology, recovery of valuable components of commodity metals such as magnesium from laterite process wastes, titanium from ilmenites, and rare metals from wastes such as phosphors and LCD monitors.
With both nickel and cobalt featuring heavily in modern industry, there is an ongoing and intense interest in ore supplies and processing, applications development, and recycling. This book presents a collection of authoritative papers covering the latest advances in all aspects of nickel and cobalt processing, including fundamentals, technology, operating practices, and related areas of Platinum-Group Metals (PGM) processing. Special emphasis is given to the treatment of sulphide and laterite ores, concentrates, and secondary materials for the production of nickel and cobalt.
Lahore is one of the cities most effected by uncontrolled noise pollution in Pakistan. The most important factor of noise pollution is the road traffic. The main objective of this study was to analyze and evaluate road traffic noise and to measure its effects on the population of Lahore city. A weighting sound level meter was used in the study. All the measurements were taken at a height of about 1.2 m from the ground at 56 sample sites. The spatial noise pattern was shown in maps. These were also drawn to show buffers dividing areas into moderate, high and extremely high risk zones in accordance with noise risk levels. The maps were additionally divided in day and night time maps, each with graduated symbols. The main day-night values were exceeding the permissible environmental standards used in Pakistan. Therefore, a survey was conducted to study the diseases caused by noise pollution in the areas with highest noise levels.
Die Reihe Islamkundliche Untersuchungen wurde 1969 im Klaus Schwarz Verlag begründet und hat sich zu einem der wichtigsten Publikationsorgane der Islamwissenschaft in Deutschland entwickelt. Die über 330 Bände widmen sich der Geschichte, Kultur und den Gesellschaften Nordafrikas, des Nahen und Mittleren Ostens sowie Zentral-, Süd- und Südost-Asiens.
The inspiration behind Poisoned Land: Vegetation of Disturbed and Polluted Areas in Pakistan arose from the dire situation of the world’s decaying environment and how pollution is impacting plants. Anthropological activities are altering the current status of flora and fauna of Pakistan. The alarming changes in nature, with its ensuing structure and composition of vegetation due to environmental pollution brought about the research for this book, as there is scant literature on the impact of pollution on plant communities. The description of nature, and the structure and composition of vegetation is very complex. Ever-increasing pollutants are leading to an unhealthy environment for living organisms, calling for there to be changes toward a healthier environment.
