Bones This paper introduced a novel semiring structure involving nonnegative integers, where operations depended on the comparison of the magnitudes of decimal digit sums.Consequently, a corresponding matrix semiring can be established on this commutative semiring.We showed that the 3-satisfiability problem can be polynomial-time reduced to solving
In Acanthocephala, the ovarian balls (floating ovaries) are distinctive structures found suspended in the fluid-filled metasoma of females and are responsible for egg production and maturation.Those structures have not been studied in Rhadinorhynchus niloticus.We aimed to investigate their ultra-structure by means of scanning and transmission elect

Snake venoms are complex protein mixtures with different biological activities that can act in both their preys and human victims.Many of these proteins play a role in prey capture and in the digestive process of these animals.It is known that some snakes are resistant to the toxicity of their own venom by mechanisms not yet fully elucidated.Howeve
The objective of the present study was to investigate selected trace and mineral elements in Royal Jelly (RJ) from Bulgaria.A total of 30 RJ samples were included in the study.The analytical procedure consisted of the microwave digestion of the RJ samples with nitric acid followed by instrumental measurement.Concentrations of Al, Ba, Ca, Cr, Cu, Fe
