Rainbow trout (Oncorhynchus mykiss) is one of the most-widely cultivated cold fresh water fish in the world. Gamasyab River, with a length of about 200 Km, is one of the longest rivers of Iran. The aim of this research is to determine the effects of trout farm effluents on this river water.  From a total of 24 trout farms in the area,  four farms were randomly selected and three sampling statio...

The idea of systems analysis and mathematical modeling for formulating and resolving river pollution issues is of relatively recent vintage and has been applied widely in the last 3 decades. The present study illustrates the utility of Beck-modified Khanna–Bhutiani model (BMKB) to determine the pollution load due to the presence of organic matter in River Ganga from its course from Devprayag to...

Rivers can be contaminated with different pollutants such as trout farms. Evaluation of the effect of trout farm on water quality is important to give new permission for trout farm construction. In current work, the effect of constructed trout farms near the Deinachal River on some physicochemical properties namely chemical oxygen demand (COD), biological oxygen demand (BOD5), dissolved oxygen ...

Deformed cross-dissolves are methods for inconspicuous interpolation between images. We describe algorithms for deformation based on scattered data interpolation methods and an improved cross-dissolve algorithm ooering better performance than a normal bidirectional cross-dissolve. Results for interpolation in the eld of medical visualization are presented.

Özet: 1960'lı yılların sonundan bu yana yazılım projeleri yürütülmektedir. Yazılım mühendisliği alanında yapılan araştırmalar bu projelerin başarı ile tamamlanması için alınması gereken önlemleri anlatsa da günümüzde hala pek çok yazılım projesi başarısızlıkla sonuçlanmaktadır. Ayrıca, bu alanda yapılan araştırma sonuçları daha çok proje süreci başlamadan alınması gereken önlemleri belirtir. Bi...

Flow injection analysis (FIA) and flow analysis (FA) were used to automate the calorimetric determination of hydrogen sulfide by the methylene blue method. A low-sensitivity FIA manifold for concentrations up to 200 PM H,S had a detection limit of 1.2 FM. A highsensitivity FIA manifold for concentrations up to 75 PM H,S had a detection limit of 0.12 PM. The C.V. was < 1% at concentrations > 10 ...
