This research aims to define a chemical, mineralogical and strontium isotope database for clayey materials collected along the Nile River banks (White Nile, Blue Atbara Main Rivers) in Sudan, be use prehistoric historic pottery provenance studies. The approach here adopted consists using tout court, without any pre-treatment, such as depuration from sand- silt-sized fractions, order maintain un...

Serum samples were obtained from 252 horses in the State of Yucatan, Mexico, from July to October 2002. Antibodies to West Nile virus were detected by epitope-blocking enzyme-linked immunosorbent assays in three (1.2%) horses and confirmed by plaque reduction neutralization test. We report the first West Nile virus activity in the State of Yucatan.

A total of 200 fish samples (100 Oreochromis niloticus (Nile tilapia) and 100 aureus (Blue tilapia)) were used for this research aimed to produce a population tilapia species that is skewed toward the male population. Three mating periods carried out in total. The males removed from hapa after each round egg production allow repercussion. Fries experimental units collected, counted, stocked tan...

Methylene blue (MB'), covalently attached to DNA through a flexible C(12) alkyl linker, provides a sensitive redox reporter in DNA electrochemistry measurements. Tethered, intercalated MB' is reduced through DNA-mediated charge transport; the incorporation of a single base mismatch at position 3, 10, or 14 of a 17-mer causes an attenuation of the signal to 62 ± 3% of the well-matched DNA, irres...

New acrylic microspheres were synthesised by photopolymerisation where the succinimide functional group was incorporated during the microsphere preparation. An optical biosensor for urea based on reflectance transduction with a large linear response range to urea was successfully developed using this material. The biosensor utilized succinimide-modified acrylic microspheres immobilized with a N...
