Structural reliability depends on uncertainties in resistance and loads. In many practical cases the resistance dominates and a reduction of uncertainty about resistance is an effective way of increasing safety. It can be accomplished by proof loading. A truncated distribution is considered and reliability indices are calculated for various proof load levels. The structural reliability is sensi...
متن کاملGenetics of childhood disorders: XI. Fragile X syndrome.
Fragile X syndrome is a common form of mental retardation with an estimated incidence of 1 per 2,000 to 4,000 in the general population. The physical manifestations associated with the syndrome include macroorchidism, large ears, a prominent jaw, moderate to severe mental retardation, and autistic-like behavior. However, physical features are not always reliable indicators of the presence of th...
متن کاملPotential anticancer agents, XI. X-ray structure determination of acantholide.
The X-ray structure of acantholide, a melampolide sesquiterpene lactone from Acanthospermum glabratum (DC.) Willd. was determined by the aid of direct methods. The compound was cytotoxic but displayed no antitumor activity. Evaluation of the X-ray and NMR data indicated that the same conformation exists in the solid state as in solution.
متن کاملX-ray studies on phospholipid bilayers. XI. Interactions with chloramphenicol.
Chloramphenicol is a widely used antibiotic with low levels of toxicity. However, scanning electron microscopy revealed morphological changes in human erythrocytes when they interacted in vitro with therapeutical concentrations of chloramphenicol. To explain this shape change, a study concerned with the possible interactions of this antibiotic with bilayers built-up of phospholipids located in ...
