Pigmented maize - a potential source of β-carotene and α-tocopherol
Among cereals, maize has the highest content of bioavailable micronutrients in grain, particularly β-carotene and α-tocopherol, which makes this crop the most appropriate for biofortification. Great genetic variability is a valuable source of micronutrients, and genotypes with enhanced grain content could be used for improvement of comme...

The possibility of application of xanthan in removal of metal ions from wastewaters
Biopolymers have the ability to absorb large amounts of water or biological fluids. They are swelling and forming hydrogels. Thanks to this, they have found a variety of applications, and among others they can be used to remove some metal ions from the water. Due to its unique structure and exceptional rheological characteristics, microbiological b...

Validation of method for cannabis identification using gas chromatography technique
The methods of analysis in forensic must be reliable in order for the results of the analysis to be accepted as evidence in court proceedings. The reliability of methods is checked through the validation process, which should be performed before introducing a method into the routine practice of the laboratory. This paper describes the procedure for...

Composting kinetics for mixture of poultry manure and wheat straw based on volatile solids content
The aim of this study was to determine the composting kinetics for mixture ofpoultry manure and wheat straw based on the volatile solids content.Experimental data was fitted with the first-order and the nth-order kinetic model.The nth-order kinetic model showed better prediction performance than the firstorderkinetic model. For the first-order kine...
