composite concrete-steel plate shear walls are the most critical resisting structural members that resist lateral and axial loads. This type of wall consisting of two steel faceplates presenting the outer skin, infill concrete and shear connectors which are used to provide the composite action of the steel faceplates with infill concrete in order to increase the strength and to reduce the local...

Longitudinal heat conduction is an important parameter in the cryogenic field, especially in cryogenic heat exchangers. In the present work, the parasitic effect of tube wall longitudinal heat conduction on temperature measurement has been studied in cryogenic laminar hydrogen flow. The effects of various parameters such as wall cold end temperature, wall thermal conductivity, gas volumetric fl...

The fungus, Candida albicans, and the bacterium, Pseudomonas aeruginosa, are opportunistic human pathogens that have been coisolated from diverse body sites. Pseudomonas aeruginosa suppresses C. albicans proliferation in vitro and potentially in vivo but it is the C. albicans hyphae that are killed while yeast cells are not. We show that hyphal killing involves both contact-mediated and soluble...

The C terminus of the major surface protein P1 from Streptococcus mutans is composed of a hydrophilic domain, an LPNTGV motif, a hydrophobic domain, and a charged tail. These features are shared by surface proteins from many gram-positive coccal bacteria. To investigate the role of the C-terminal domains in antigen P1 surface localization, full-length and truncated P1 gene constructs, which wer...

Cells of proso millet (Panicum miliaceum L. cv Abarr) in liquid culture and leaves of maize seedlings (Zea mays L. cv LH51 x LH1131) readily incorporated d-[U-(14)C]glucose and l-[U-(14)C]arabinose into soluble and cell wall polymers. Radioactivity from arabinose accumulated selectively in polymers containing arabinose or xylose because a salvage pathway and C-4 epimerase yield both nucleotide-...

Cell-wall-associated and extracellular alpha-glucosidases were purified to homogeneity from Saccharomycopsis fibuligera KZ growing on a medium containing cellobiose as the sole source of carbon; this substrate has the greatest inducing effect on the production of both forms of the enzyme. Depending on the source of carbon, 75-90% of the enzyme is associated with cell wall, from which it can be ...

Candida albicans is the major fungal pathogen of humans. Its adhesion to host-cell surfaces is the first critical step during mucosal infection. Antimicrobial peptides play important roles in the first line of mucosal immunity against C. albicans infection. LL-37 is the only member of the human cathelicidin antimicrobial peptide family and is commonly expressed in various tissues, including epi...

the baluarte do cavaleiro is part of the stone masonry wall system existing in the city ofchaves of portugal and it is a construction dated from the xvii century. the baluarte docavaleiro is formed by three walls (north-east, ne; south-east, se; south-west, sw) andby two junction elements (designated here by cunhais). the se wall has suffered twocollapses recently. the main objective of this re...
