A new transposon library constructed in the background of the highly and homogeneously methicillin-resistant Staphylococcus aureus strain COL yielded 70 independent insertional mutants with reduced levels of antibiotic resistance. Restriction analysis with HindIII, EcoRV, EcoRI, and PstI and then Southern hybridization with probes for the transposon and for the femA-femB gene demonstrated that ...

femA is a chromosomally encoded factor, occurring naturally in Staphylococcus aureus, which is essential for the expression of high-level methicillin resistance in this organism. The production of a low-affinity penicillin-binding protein, PBP2a or PBP2', which is intimately involved with methicillin resistance in S. aureus, is not influenced byfenmA. To elucidate a possible physiological funct...

STUDY DESIGN Retrospective controlled cohort study comparing the in-brace correction of two samples of scoliosis patients with braces of different computer aided design (CAD). PURPOSE In-brace correction and compliance correlate with outcome. The more standardized CAD braces that are available should enable improved in-brace correction and outcome. This study compared recent CAD brace develop...

The nonlinear static procedure (NSP) or pushover analysis in FEMA-273 [FEMA, 1997] has become a standard procedure in current structural engineering practice. Seismic demands are computed by nonlinear static analysis of the structure, which is subjected to monotonically increasing lateral forces with an invariant height-wise distribution until a target displacement is reached. None of the curre...

Damage assessment involves the difficulties of defining, assessing, and modelling the variables involved as well as handling uncertainty. This paper presents a methodology for the damage assessment of RC structures based on fuzzy logic. In the proposed system, the variables defined are the same as those used in the “rapid screening procedure” developed by FEMA and described through a data colle...

Yapılardaki deprem hasarının tahmini, can ve mal kaybını önleme açısından oldukça önemlidir. Hasar plastik mafsal parametrelerinin şekil değiştirme sınır durumlarının gerçek yapı davranışını yansıtması oranında başarılı olmaktadır. Yapı tasarımında mevcut değerlendirmesinde çeşitli standartlar ile parametreleri değerleri belirlenmiştir. Federal Acil Durum Yönetim Kurumu (FEMA) Amerikan İnşaat M...
