which had Galileo among its members. He commissioned artists to record plants, birds and animals for his museum and a pictorial encyclopaedia that attempted to understand and classify both the natural and ‘man-made’ world. Alexander Marshal’s floral paintings were compiled at a time when the cultivation of gardens had become a pursuit of scholars and collectors, keenly interested in exotic spec...
The Front Cover shows the Karlštejn Castle, a large Gothic castle founded in 1348 by Charles IV, Holy Roman Emperor-elect and King of Bohemia (and founder University Prague). served as place for safekeeping Imperial well Bohemian crown jewels, holy relics, other royal treasures. From synthetic chemist's point view, chiral ligands enabling high asymmetric inductions can be also considered jewels...
در قسمت اول رساله واکنش تشکیل کمپلکس یون تالیم با calix[4]crown-6 و سه مشتق دیگر آن با روشهای 203tl , 1h nmr مورد بررسی قرار گرفتند. همچنین کمپلکس یک هسته ای tlclo4 و 1,3-calix[4]bis-o-benzo-crown-6 در حالت جامد تهیه شد و ساختار بلوری x-ray آن تعیین گردید. سینتیک و مکانیسم تفکیک و تغییرات پیکربندی کمپلکس تالیم و calix[4]crown-6 با دینامیک 1h nmr مورد مطالعه قرار گرفت. یک منحنی محدب آرنیوس برای ...

حلقه های هتروسیکل هشت تایی ساده مثل 1، 3، 5 و -7تتراکسوکان دو صورت بندی قایق-صندلی (bc) و تاجی (crown) دارند. صورت بندی قایق-صندلی (bc) انرژی وارونگی حلقه متوسطی (حدود 33/5kj/mole) دارد. وارونگی حلقه صورت بندی های تاجی (crown) عموما از طریق تبدیلات درونی همراه با سد انرژی نسبتا بزرگتر (بیش از 50kj/mole) نسبت به قایق-صندلی که نسبتا به آسانی وارونه می شوند، انجام می گردد. مولکول 3 و -7بیس (m-نیتر...
We review the properties of classical p-brane solutions to supergravity theories, i.e. solutions that may be interpreted as Poincaré-invariant hyperplanes in space-time. Topics covered include the distinction between elementary/electric and soli-tonic/magnetic solutions, examples of singularity and global structure, relations between mass densities, charge densities and the preservation of unbr...
Data from the first run of the BABAR detector at the PEP II accelerator are presented. Measurements of many rare B decay modes are now possible using the large data sets currently being collected by BABAR. An overview of analysis techniques and results on data collected in 2000 are described.
