Gram-negative bacteria protect themselves with an outermost layer containing lipopolysaccharide (LPS).O-antigen-specific bacteriophages use tailspike proteins (TSP) to recognize and cleave the O-polysaccharide part of LPS.However, O-antigen composition and structure can be highly variable depending on the environmental conditions.It is important to
Background: In the Maloideae, pericarp cells were discovered, previously not described for this subfamily, the structural units of tannosome.Data on the tannosomes merge in the vacuoles to form tannoglobules has been obtained for the first time.Methods: The samples were fixed in glutaraldehyde and subjected to a standard procedure of dehydration, c
The fluid flow pattern and free surface fluctuation in a mold profoundly influence both molten steel solidification and molten slag thermodynamics behavior in the continuous casting process.In addition, the fluid flow and surface fluctuation behaviors are important factors of inclusions floatation, meniscus hook formation, and shear layer instabili
