Phyllanthus niruri is an important medicinal plant. To standardize the extract and guarantee its maximum benefit, processing methods optimization ought to be amenable and beneficial. Herein, three dried P. niruri samples, air (AD), freeze (FD) and oven (OD), extracted with various ethanol to water ratios (0%, 50%, 70%, 80% and 100%) were evaluated for their metabolite changes using proton nucle...

Two faba bean (Vicia faba L.) subspecies major and minor and lentil seeds grown in Algeria were separated into cotyledons and hulls. These fractions, together with their corresponding whole seeds, were extracted with two solvents, aqueous (70%) acetone and (80%) ethanol, and evaluated for antioxidant activity in relation to their phenolic contents. Acetone selectively extracted tannins from fab...

This paper gives an overview of the KULRoT 99 team. This team is based on our last year's team. The major problem we experienced with KULRoT 98 was a slow reaction time. The cause of this problem was related to bad synchronization and an insuucient notion of time. To tackle this problem, we switched to a new architecture that gives each soccer player a better notion of time. Preliminary results...

Anthocyanins, which are natural pigments and nutraceuticals, can be extracted from plant materials using enzyme-assisted methods. However, the enzymes used often expensive, fragile, hard to recover/reuse. In this study, cellulase ?-amylase were immobilized on amino-functionalized magnetic nanoparticles prepare a nanobiocatalyst. The in nanobiocatalyst exhibited higher stability greater catalyti...

Aedes albopictus and aegypti are two synanthropic, anthropophilic container-breeding mosquitoes. These species very annoying, but also vectors of dengue, chikungunya, yellow fever, Zika, Usutu viruses, other pathogens. Because these mosquitoes breed close to humans, cheap homemade methods, as alternatives commercial insecticides, could be important for their control. Coffee being a common bever...

Contamination of drinking water by microbiological and chemical agents can lead to adverse health effects. In England and Wales, the Chemicals Hazards and Poisons Division (CHaPD) of the Health Protection Agency provides expert advice on the consequences to public health of chemical contamination incidents affecting drinking water. In this study, we extracted data from the National Database on ...
