The Renal Organs of Certain Decapod Crustacea

The anatomy and physiology of the posterior stomach nerve (p.s.n.) in some decapod crustacea.

One of the major paired nerves in the decapod stomatogastric nervous system innervates the posterior part of the gastric mill. The morphology has been completely described previously only in Pugettia producta. This nerve is called the posterior stomach nerve (p.s.n.) in this paper. It is redescribed for Homarus vulgaris, and less detailed information is given for Palinurus vulgaris and Cancer p...

Neogene Decapod Crustacea from Southern Chile

Twelve species of Neogene decapod crustaceans are described from late Miocene and early Pliocene deposits in the Valdivia, Osorno-Llanquihue, and Chiloé basins as well as from Mocha Island, offshore from the Temuco Basin, southern Chile. New species of thalassinideans include Ctenocheles notialis and Axianassa? chilensis. Axianassa Schmitt, 1924, has not been reported previously in the fossil r...

some properties of fuzzy hilbert spaces and norm of operators

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...

synthesis and characterization of some macrocyclic schiff bases

ماکروسیکلهای شیف باز از اهمیت زیادی در شیمی آلی و دارویی برخوردار می باشند. این ماکروسیکلها با دارابودن گروه های مناسب در مکانهای مناسب می توانند فلزاتی مثل مس، نیکل و ... را در حفره های خود به دام انداخته، کمپلکسهای پایدار تولید نمایند. در این پایان نامه ابتدا یک دی آلدئید آروماتیک از گلیسیرین تهیه می شود و در مرحله بعدی واکنش با دی آمینهای آروماتیک و یا آلیفاتیک در رقتهای بسیار زیاد منجر به ت...
