The keystone species concept is a useful ecological concept to explain how some species exert a strong force on their community structure; this paper strives to expand the definition to include species that are used in zootherapy, i.e., the use of animals for medicinal purposes.Honey Cutlery Tray bees (Apis mellifera) can be considered a zootherapy
A comprehensive analysis of crystallographic data of 565 high-resolution protein homodimers comprised of over 250,000 residues suggests that amino acids form two groups that differ in their tendency to Horse Care distort or symmetrize the structure of protein homodimers.Residues of the first group tend to distort the protein homodimer and generally
Purpose.The purpose of this work is to determine the energy losses in the shock absorber of the freight car whose wheel-set moves in the derailed state on the track panel depending on the axle load and structural parameters of spring suspension.Methodology.On the basis of spring suspension construction analysis and operating principle of the fricti
Compulsive alcohol drinking is a key symptom of alcohol use disorder (AUD) that is particularly resistant to treatment.An understanding of the biological factors that underly compulsive drinking will allow for the development of new therapeutic targets for AUD.One animal model of compulsive alcohol drinking involves the addition of bitter-tasting q
Consider the scattering of an electromagnetic time-harmonic plane wave by an infinite cylinder having an open crack and a bounded domain in as cross Cutlery Tray section.We assume that the crack is divided into two parts, and one of the two parts is (possibly) coated on one side by a material with surface impedance.Different boundary conditions are
