the present study explored the embryonic and larval development of an endangered fish species nandus nandus and resolved larval growth performances with the dietary supplementation of different types of lipids. fertilized eggs were collected from fiber glass tanks immediately after spontaneous spawning of n. nandus, which were fed with a 1% phospholipid (squid meal) supplemented diet for 3 mont...

This study evaluated the effects of Drinking Thyme Essence (DTE) (Zero, 0.10, 0.15 and 0.20 mL/L) on growth performance, immune response and changing of intestinal bacterial population in broiler chickens. A total number of 500 day old male broiler chicks (Ross 308), were randomly assigned to 4 treatments with 5 replicates and 25 chickens per each, based on a completely randomized design (CRD)....

Density, distribution, and nutritional quality of plants are the causal basis of host plant selection in aphids. Nutritional qualities of a plant vary according to its growth stage and also in response to seasonal variation. How host plant growth stages shape aphid performance was studied in Aphis spiraecola Patch (Homoptera: Aphididae) on the perennial Siam weed, Chromolaena odorata (L.) King ...

Bambara groundnut (Vigna subterranea (L.) Verdc.) is an indigenous grain legume. It occupies a prominent place in the strategies to ensure food security in sub-Saharan Africa. Development of an efficient in vitro regeneration system, a prerequisite for genetic transformation application, requires the establishment of optimal conditions for seeds germination and plantlets development. Three type...

Résumé Le Moullac G., A. Van Wormhoudt, AQUACOP. Aquat. Living Resour., 1994, 7 , 203-210. Activity of digestive enzymes (trypsin, chymotrypsin and amylase) was studied in relation with food in Penaeus vannamei larvae first stages. Microparticles containing casein involved the decrease of soluble protein content and enzyme activities. Specific trypsin activity but not chymotrypsin was correlate...

drought is random and nonlinear phenomenon and using linear stochastic models, nonlinear artificial neural network and hybrid models is advantaged for drought forecasting. this paper presents the performances of autoregressive integrated moving average (arima), direct multi-step neural network (dmsnn), recursive multi-step neural network (rmsnn), hybrid stochastic neural network of directive ap...

This paper is a report of new musical instrument/ interface in which the main concept is "untouchable". I will report on not only the system design but also on the performances as applications. The new musical instrument/interface is constructed with infrared rays distance sensors and optical distance sensors. In attending some concerts of computer music in the past, I was inspired with perform...

Th is paper presents estimates of world economic growth for 1970-2000, and changes in the intercountry and interpersonal distribution of world income between 1980 and 2000. Th ese estimates suggest that, while the rate of growth of the world economy slowed in the 1980-2000 period, and average within-country inequality worsened, the distribution of world income among individuals, nevertheless, i...
