in order to evaluate the effects of chlorella on broiler performance and immune system, an experimentwas performed by using 80 ross 308 male broiler chicks. the experiment was accomplished incompletely randomized design including 5 treatments with 4 replication and 4 observations in eachreplicate. the basal diet was based on corn-soybean meal (control) and without any additives. agraded level o...

The exponential growth in transmission of multimedia over the Internet and unsecured channels communications is putting pressure on scientists engineers to develop effective efficient security schemes. In this paper, an image encryption scheme proposed help solve such a problem. implemented three stages. first stage makes use Rule 30 cellular automata generate key. second utilizes well-tested S...

background: micropatterning is becoming a powerful tool for studying cells in vitro. this method not only uses very small amount of material but also mimic the microenvironment structure present in living tissues better than flask culturing techniques. in previous studies using micropatterning of extracellular matrix proteins on glass surfaces, the rate of protein detachment from the surface wa...

the effects of methanolic extract and leaf powder of artemisia annua were studied on performance, cellular and humoral immunity in 240 cobb broiler chicks in a completely randomized design. control group did not receive any treatment. the chicks in the second and third groups were fed with feed which contained 2000 and 4000 ppm plant extract in diet and in the groups 4, 5 and 6 chicks received ...

we prove that if $m$ is a monoid and $a$ a finite set with more than one element‎, ‎then the residual finiteness of $m$ is equivalent to that of the monoid consisting of all cellular automata over $m$ with alphabet $a$‎.

objectives: the aim of the present study was to investigate immunotoxic effect of safranal (saf), a main component of crocus sativus essential oil, using balb/c mice. materials and methods: saf was administered intraperitoneally at doses of 0.1, 0.5 and 1 ml/kg for 3 weeks. hystopathological examination of spleen and bone marrow, cellularity of spleen, delayed type of hypersensitivity (dth) res...

Chronic and recurrent bone infections occur frequently but have not been explained. Staphylococcus aureus (S. aureus) is often found among chronic and recurrent infections and may be responsible for such infections. One possible reason is that S. aureus can internalize and survive within host cells and by doing so, S. aureus can evade both host defense mechanisms and most conventional antibioti...
