It is easy to think of using sawtooth steel plate on the surface of column to increase the interfacial friction in the temporary RC column underpinning structure.However, there is little research on the friction properties between sawtooth steel plate and concrete.108 working condition of double interface shear tests were conducted for measuring th
Methanotrophic bacteria are entities with innate biocatalytic potential to biofilter and oxidize methane into simpler compounds concomitantly conserving energy, which can contribute to copious industrial applications.The future and efficacy of such industrial applications relies upon acquiring and/or securing robust methanotrophs with taxonomic and
Background: Major intercontinental outbreaks of invasive meningococcal disease associated with the Hajj occurred in 1987, 2000, and 2001.Mandatory meningococcal vaccination for all pilgrims against serogroups A and C and, subsequently, A, C, W, and Y controlled the Globe epidemics.Overseas pilgrims show excellent adherence to the policy; however, v
Large numbers of dead seals with characteristic spiral lesions have been washing ashore around the North Atlantic over the past two decades.Interactions with ship propellers and shark predation Engine Cold Air Intake have been suggested as the likely causal mechanisms.However, new evidence points towards a more likely candidate: grey seal predation
