the present study was carried out to evaluate the effects of dietary nano-structured zeolite (nz) levels on reduction of aflatoxin b1 (afb1) in the diet of rainbow trout (oncorhynchus mykiss) for 56 days. for this purpose, 270 fish (23 ± 3.7 g) were randomly distributed into 6 groups including c (control), nz0.5 (basic ration + 0.5 % nano-structure zeolite), nz1 (basic ration + 1 % nano-structu...

The chemical behavior in an aqueous medium of a natural zeolitic material, NZ (mainly consisting in crystals of the zeolites clinoptilolite/heulandite) has been studied through electrochemical techniques, complemented by atomic absorption spectrometry. The time dependence of the conductivity of the aqueous medium in the presence of NZ, showed a steep increase at the beginning followed by a slow...

magnetite (feo.fe2o3) nanoparticles immobilized on silica and modified by treatment apolaccase were used to decolorize the industrial wastewater from basic red 9 (br9 by way of fenton and fenton-like processes. the surface changes to the silica were determined by scanning electron microscopy, fourier transform infrared spectroscopy, x-ray diffraction and energy-dispersive x-ray spectroscopy. th...

The objective of this experiment was to determine the effect of dietary grain on calcium homeostasis. Six rumen-fistulated dairy cows with 3 or more previous lactations and no history of parturient paresis were randomly assigned to a sequence of diets in a crossover study with 4 periods of 10 days each. Dietary treatments were: A control ration consisting of wrap grass silage alone (1), the con...

BACKGROUND Fossil fuels' pollution and their non-renewability have motivated the search for alternative fuels. Some common example of seed oils are sunflower oil, date seed oil, soy bean oil. For instance, soy methyl and soy-based biodiesel are the main biodiesel. Biodiesel is a clean diesel fuel that can be produced through transesterification reaction. Recycled cooking oil, on the other hand,...

Plasmonics based sensors have been a prominent area of research. Plasmonics based sensors are widely used in bio sensing and many other applications. The basic mechanism in which these sensors operate is that there are metal nano particles that are separated by a very small distance between them. The dimensions of these nano particles is much smaller than the incident light [1]. For sensing pur...

The effects of fat source (0.7 kg of fatty acids from extruded soybeans or palmitic acid), of sodium bicarbonate (0.3 kg) plus straw (1 kg) and the interaction of these treatments on the content of conjugated linoleic acid (CLA) in the milk of dairy cows were examined. During nine weeks a group of 10 cows received a ration with palmitic acid and bicarbonate plus straw (ration PAB). During three...
