Pigments from paint palettes and a grindstone excavated the pharaonic town of Amara West (c. 1300–1050 BCE), which lies between Second Third Cataracts Nile, were examined using polarized light microscopy, attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR), X-ray diffraction, scanning electron microscopy with energy dispersive spectroscopy. Most pigments consistent ty...

The susceptibility of 12 strains of Mobiluncus curtisii and 10 strains of M. mulieris to 23 antimicrobial agents and 15 other compounds was determined. All strains were susceptible to chloramphenicol, clindamycin, rifampin, tobramycin, vancomycin, virginiamycin, and all beta-lactam antibiotics tested, including imipenem. One strain of M. mulieris was resistant to erythromycin and josamycin. All...

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...

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...

During the last 100 years the Ethiopian upper Blue Nile Basin (BNB) has undergone major changes in land use, and is now potentially facing changes in climate. Rainfall over BNB supplies over two-thirds of the water to the Nile and supports a large local population living mainly on subsistence agriculture. Regional food security is sensitive to both the amount and timing of rain and is already a...

Phenothiazine-based photosensitisers have been employed in photoantimicrobial research for nearly 80 years, both as lead and novel compounds. However, the main structural variations have mainly involved the auxochromic side chains and little has been reported concerning either peripheral substitution or structures with chromophores other than those of the phenothiazinium or annelated benzo[a]ph...
