Evaluating performances, particularly that of researchers, has been considered as one of the most important problems in the fields of education and research. In many cases, even one score in evaluating a work would lead to getting or missing a prize unjustly. There can be found some Quranic teachings in the field to solve the problem. Paying attention to personal rights of those being criticize...
The effects of substitution of seaweed, Sargassum ilicifolium, by replacing protein resources, in Litopenaeus vannameii diets was studied. It was carried out by incorporation of raw powdered seaweed at three levels, 0% as control treatment, 5% (C), 10% (B) and 15%(A) each with four replications in isoprotein, (33%) and isocaloric (355kcal.100-1) diets.. Binder properties of seaweeds in differe...
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...
Synthesis--particularly by electrochemical anodization-, growth mechanism and chemical sensing properties of pure, doped and mixed titania tubular arrays are reviewed. The first part deals on how anodization parameters affect the size, shape and morphology of titania nanotubes. In the second part fabrication of sensing devices based on titania nanotubes is presented, together with their most no...
An 8-week feeding trial was conducted to evaluate the effects of dietary commercial prebiotic A-Max, a mixture of mannan oligosaccharides, fructo oligosaccharides and β glucan, on growth and hemato-immunological parameters of great sturgeon (Huso huso) juveniles. After acclimation, fish (initial weight of 28.79±0.85 g) were placed into 12 tanks (30 fish per tank). Basal diet (containing 44%...
Understanding the relationship between growth and temperature will aid in the evaluation of thermal stress and threats to ectotherms in the context of anticipated climate changes. Most Pecten maximus scallops living at high latitudes in the northern hemisphere have a larger maximum body size than individuals further south, a common pattern among many ectotherms. We investigated differences in d...
