This research describes application of a mesoporous nanostructured material based on basic ionic liquid anchored to silica, i.e. nano-2-(dimethylamino)-N-(silica-n-propyl)-N,N-dimethylethanaminium chloride {nano-[DMSPDE][Cl]}, as a highly effective and heterogeneous nanocatalyst for the production of 2-amino-4H-chromenes. The one-pot multi-component ...

The aims of this study were to determine the feeding effect of diets containing different ratio of ω-3 and ω-6 fatty acids and organic Zn on egg production and quality of Magelang duck. A total of 90 ducks of 20 weeks old were randomly divided into 18 experimental units by assigning a completely randomized design with 6 treatments and 3 replications. There were 6 dietary treatments, namely 1) r...

We examined the relative importance of parental nutritional condition and larval food ration on the rates of development, growth and metamorphosis of larvae of Strongylocentrotus droebacḧ iensis (Muller) in a laboratory experiment. Parents were reared for 22 months on either a high 21 ration of kelp (Laminaria spp., 6 days week ) supplemented with mussel flesh (Mytilus spp., 1 21 21 day week ) ...

Two experiments were carried out to evaluate the effects of indigestible neutral detergent fiber (iNDF) of ration for estimation of rumen degradability of fiber in sheep. In experiment 1, to determine feed iNDF, four ruminal fistulated Zel ewes were used. Three grams of alfalfa hay, corn silage, barley grain, wheat bran, ration 1 (including alfalfa hay and concentrate), and ration 2 (including ...

This study was conducted to evaluate the effects of dietary forage type and concentrate-to-forage ratio (CTFR) on CH4 emissions from dairy cows in China using the SF6 tracer method. Rumen fluid concentrations of NH4-N and VFA, rumen fluid pH, and daily milk yield were measured as well. The dietary regimens included: corn stalks (dry corn stalks after corn harvest) as the forage source at CTFR o...

In this project, versatile processing techniques are established for improving the internal and external quantum efficiencies of Si MOSLEDs via the detuning the size and density of high-aspect-ration Si nano-rod and buried Si nanospheres. A rapid thermal annealing synthesis of metallic nanodot array is realized to control the size and density control of metallic nanodots as an etching mask for ...

Veterinarians increasingly play a major contributory role in dairy practice and management. Withincreasing importance of economical pressures, bioenvironmental limits and increasing demand for higherquality products, veterinarians are more involved in nutrition management and advice, both from aneconomical view of productivity and preventive aspects of veterinary medicine. The concept of food a...
