بررسی توانایی Anodonta cygnea در جذب ترکیبات ازته و فسفاته در سیستم مدار بسته

The Behaviour of Anodonta Cygnea L.( and Its Neurophysiological Basis

بررسی قابلیت صدف دو کفه ای Anodonta cygnea در تصفیه بیولوژیمی فاضلاب شهری ( در سیستم باز )

تولید پساب های ناشی از فعالیت های کشاورزی و صنعتی، باعث برهم خوردن کیفیت آب ها شده است. فسفات و نیترات موجود در این پساب ها، مزاحمت های محیط زیستی بسیاری ایجاد می نمایند. کاهش مقدار مواد محلول باقیمانده در فاضلاب پس از طی فرآیند تصفیه و نیز استفاده از روش های بیولوژیکی به جای روش های شیمیایی موجود، دلیل اصلی انجام این تحقیق بوده است. صدف Anodonta cygnea در میان صدف های آب شیرین، یکی از انواع مه...

Degenerate Four Wave Mixing in Photonic Crystal Fibers

In this study, Four Wave Mixing (FWM) characteristics in photonic crystal fibers are investigated. The effect of channel spacing, phase mismatching, and fiber length on FWM efficiency have been studied. The variation of idler frequency which obtained by this technique with pumping and signal wavelengths has been discussed. The effect of fiber dispersion has been taken into account; we obtain th...

Morphological and chemical characterization of mineral concretions in the freshwater bivalve Anodonta cygnea (Unionidae).

The freshwater mussel Anodonta cygnea is commonly used as a model organism for biomineralization studies, its peculiar morphofunctional properties also make it an excellent environmental biomonitor. The first detailed on the calcareous concretions from gill and mantle tissue, as well as fluids of the freshwater bivalve A. cygnea, supported by histological, scanning, spectrometry, and spectrosco...

The ionic basis of axonal conduction in the central nervous system of Anodonta cygnea (Mollusca: eulamellibranchia).

The bivalve mollusc Anodonta cygnea appears to be unique in possessing the most dilute body fluids so far described in the Animal Kingdom. The osmotic concentration of the blood of this species has been found to amount to only about 44-0 m-osmole, with a sodium concentration which averages 15-6 mM/kg. (Potts, 1954). It is difficult to explain the ionic basis of electrical activity of excitable ...
