Chemical Profiling and Industrial Viability of Neem Seed Oil: A Comprehensive Study for Sustainable Biodiesel Production
No full textThe study explores the chemical composition of neem seed oil, highlighting its potential for commercial biodiesel production and various industrial applications. The oil, with a liquid state, pale greenish-yellow color, and pleasant odor, yielded 32.1%, surpassing industrially extracted oils like soybean and cottonseed. Factors influencing its composition include seasonal variations, geographical origin, genetic disparities, growth stages, plant segments, and postharvest processing. Despite these, neem seeds meet the required oil content percentage for large-scale industrial biodiesel production. However, challenges like high free fatty acid content and elevated acid values necessitate acid esterification before alkaline transesterification, potentially increasing production costs. The study also highlights the importance of appropriate seed processing practices to optimize oil yield and quality
Settlement & ceramics in Southern Iran: An analysis of the Sasanian & Islamic periods in the Williamson collection
No full textBetween 1968 and 1971, Andrew George Williamson carried out one of the most extensive and ambitious archaeological surveys undertaken in the Near East. Williamson’s survey of over 1,200 archaeological sites distributed widely through southern Iran represents the most detailed archaeological study of the region. Williamson's untimely death in Oman in 1975 prevented the work from being completed or published, and as a result, the information from his pioneering study have remained generally obscure. A sizable portion of the finds that Williamson collected during the survey (17,000 sherds) were exported to the UK and deposited at the Ashmolean Museum in Oxford, along with much of the documentation associated with the project. A full synthesis of this material has not until now been attempted. Recognising the important scientific value of Williamson's survey, a detailed study of the Collection was initiated with the aim of: 1) providing a complete catalogue of the Collection; 2) creating a list and map of all sites that Williamson visited and 3) analysing the resulting dataset. The discussion presented below, which describes the results of the research on the Collection, has been broken into two sections. The first section describes Williamson’s work and the contents of the Collection (Chapter 1), and explains the methodology and approach that has been taken during this study (Chapter 2). The second section uses the data generated from the study to analyse regional settlement trends (Chapter 3) and the changing distribution of a selection of key ceramic wares (Chapter 4). Together these themes contribute towards a model for the long-term economic development along the northern shores of the Persian Gulf, ๒ an area that has previously suffered from a major lack of primary archaeological research. Drawing on this study and the more detailed now be possible, for the first time, to set out a scheme that covers the Persian Gulf region as a whole
