The influence of sound exposure on movement and food-finding behaviour of red cherry shrimp Neocaridina davidi
Background and Objectives: Many animal species are currently experiencing anthropogenic pollutions in their habitat. Noise pollution from human activities affects many species of animals. Noise pollution in terrestrial and aquatic ecosystems is prominently recognized as a source of stress and disruption of biological activities, and an important and pervasive global environmental pollutant. Rec...
متن کاملEffect of Temperature on Biochemical Composition, Growth and Reproduction of the Ornamental Red Cherry Shrimp Neocaridina heteropoda heteropoda (Decapoda, Caridea)
The effect of water temperature on biochemical composition, growth and reproduction of the ornamental shrimp, Neocaridina heteropoda heteropoda, was investigated to determine the optimum temperature for its culture. The effect of embryo incubation temperature on the subsequent performance of juveniles was also evaluated. Ovigerous females and recently hatched juveniles (JI) were maintained duri...

چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...
15 صفحه اولsome 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...
15 صفحه اولGrowth performance and some haematological parameters of ornamental striped catfish (Pangasianodon hypophthalmus) fed on dietary nucleotide
The effects of dietary nucleotide (NT) on growth performance and some haematological parameters of striped catfish (Pangasianodon hypophthalmus) were investigated. Different levels of the NT (0, 0.25, 0.5, 0.75, 1%) in the diet were used for 10 weeks starting on the fish weighted (1.52 ± 0.11 g). The results showed that NT supplementations did not improve final weight, weight gain, food conserv...
