Effects of different dietary supplements of plant carotenoid sources on growth, coloration and behavioural activities of Trichogaster fasciata were carried out. Three groups of fish were fed with petal powder of rose (Rosa chinensis), China rose (Hibiscus rosasinensis) and marigold (Tagetes erecta) separately as carotenoid source along with the same basic ingredients for 90 days. The mean final...

Abstract In this note we obtain estimates on the relative growth of normal subgroups non-elementary hyperbolic groups, particularly those with free abelian quotient. As a corollary, deduce that associated series fail to be rational.

In the discussions of trading, unemployment and income distribution inequality, this question is raised by economists that in economic development of developing and developed countries, which policy is necessary in the first stage. Is trading liberalization the pre-requirement of transfer from a close economy to a relative open economy and is it necessary for the developed economy compared to o...

in order to study the effect of intercropping (mix cropping) of three sesame genotypes (sabzevar, kashmar and kalat) a field experiment was conducted based on a complete randomized block design with three replications at research station, college of agriculture ferdowsi university of mashhad, in year 2009. the experimental treatments were: sole cultivation of sabzevar, kalat, kashmar genotypes,...

in order to determine the best traits related to indirect increasing of grain yield, five wheat genotypes (zagros, tajan, durum cul., kohdasht and n-81-18 line) were evaluated by using randomized complete block design (rcbd) with 4 replications in research field of gorgan university of agricultural sciences and natural recourses. the studied traits included leaf area index (lai), crop growth ra...

the growth rate of carbon nanotubes in chemical vapor deposition is simulated by using a theoretical analysis of the phonon vibration of the system. simulations demonstrate that the growth rate of carbon nanotubes with larger diameters is smaller because of higher damping factors and carbon nanotube inertia. an optimum temperature for the growth rate is calculated for a carbon nanotube on fe ca...
