متن کاملParasites of some bonyfish species from the Boojagh wetland in the southwest shores of the Caspian Sea
The Boojagh international wetland with a surface area of 80 hectares and 25 fish species is located in the southwest shores of the Caspian Sea (Guilan province, Iran), but there is no report about fish parasites in this wetland. In the present study, a total of 553 individuals of 8 fish species including Cyprinus carpio (n=71), Abramis bjoerkna (n=153), Carassius auratus gibelio (n=89), Esox...
متن کاملIntegrated Membrane Processes (EDR-RO) for Water Reuse in the Petrochemical Industry
The objective of this work was to apply a hybrid process, including electrodialysis reversal (EDR) and reverse osmosis (RO) to the treatment of petrochemical wastewater in order to obtain process water for reuse. A water balance was carried out to defne the main water consumers and the process step that could receive the produced water. Additionally, toxicity assays wer...
متن کاملThermodynamic study of Cu(II) ion-selective membrane electrode based on his (N-salicylidene-3,32-diamino dip hen y sulfone
The effect or temperature on the behavior of Cu(II) Mr electrode based on bis(N-sahcylidenc-3.3'-4iaminodiphenyl) sulfune(BSDDS) was studied. This electrode showed a good Nemstian response in the temperaturerange of 20-50 C. Also, the behavior of the synthesized electrode was inngigated in the mixed solvents'ethanol+water" and "dioxane +water'.
متن کاملModule cohomology group of inverse semigroup algebras
Let $S$ be an inverse semigroup and let $E$ be its subsemigroup of idempotents. In this paper we define the $n$-th module cohomology group of Banach algebras and show that the first module cohomology group $HH^1_{ell^1(E)}(ell^1(S),ell^1(S)^{(n)})$ is zero, for every odd $ninmathbb{N}$. Next, for a Clifford semigroup $S$ we show that $HH^2_{ell^1(E)}(ell^1(S),ell^1(S)^{(n)})$ is a Banach sp...
