In recent years the great advances have occurred in the field of Information & Technology, there are several services provided by the I.T. to an ordinary user some of them may possibly depend on each other, as we know the critical aspect is Information on which everything depends. As the globalization increases the information regarding every prospective is also get increased ,so it is very nec...

Total syntheses of ent-penicillones A (ent-1) and B (ent-2) from 3,5-dimethylcatechol (3) were accomplished in 10 and 9 synthetic steps, respectively. A carbohydrate-templated asymmetric intramolecular Diels-Alder reaction of a masked o-benzoquinone (MOB) 9 and an aqueous acid-catalyzed intramolecular aldol reaction are the key synthetic steps. In addition, the absolute configurations of the bi...

On an anatomical basis, cornea may be divided into three major parts: the fibrous stroma, the overlying epithelium, and endothelium. Epithelial and endothelial cells contribute approximately 20% of the total wet weight of beef cornea, and their integrity is essential for stromal maintenance (1). Of the three major parts of cornea, epithelial cells have the highest oxygen consumption that can be...

The Conceptual Design Report (CDR) on “An International Accelerator Facility for Beams of Ions and Antiprotons” formed the basis of the present Letter of Intent (LoI). The scientific motivation for a broad variety of atomic physics experiments with highly-charged heavy ions at the new facility and the first concepts of a practical realization are extensively reported in Section 2 of the CDR ent...

Broadcasting and Streaming Stored Video Despina C. Saparilla Supervisor: Prof. Keith W. Ross This thesis studies distribution schemes for stored video over broadcast networks and over the Internet. In the rst part of the thesis we consider designing near Video on Demand (VoD) systems that minimize start-up latency while maintaining high-image quality. We propose a novel scheme for near VoD whic...
