چکیده
The paper updates Isler's monograph of 1971 regarding the structures of naturally occurring carotenoids, their chemical reactions and their stereochemistry. Around ninety new structures are reported, including the new series of C30-carotenoids, enolized /3-diketones and several carotenoids with 2-hydroxy 3-rings. Progress in stereochemistry resulting in the configurational assignment of eleven additional chiral carotenoid end groups and the absolute configuration of around thirty carotenoids, including C50-carotenoids, is discussed.

Two New and Novel Cascaded Multilevel Inverters with Less Number of Components Utilizing Series Submultilevel Inverters
In this paper, two new cascaded inverters are proposed, by using the series connection of new Submultilevel inverters. Each of the proposed Submultilevel inverters consists of three batteries and eight power switches. Four algorithms are presented to determine the voltages of these batteries for each of the proposed structures. In this study the comparison between the proposed structures with c...

متن کاملA New Analytical Solution for Determination of Acceptable Overall settlement of Heap Leaching Structures Foundation
There are some artificial and natural materials on foundation of heap leaching structures. Geomembrane liner is the most important artificial isolated layer of these structures. The thickness of this layer is about 1 to 2 mm. Foundation overall settlement of such structures changes the primary length of the geomembrane layer. If the strain of geomembrane is more than allowable one, the layer wi...
