Clamp loaders load sliding clamps onto primer-template DNA. The structure of the E. coli clamp loader bound to DNA reveals the formation of an ATP-dependent spiral of ATPase domains that tracks only the template strand, allowing recognition of both RNA and DNA primers. Unlike hexameric helicases, in which DNA translocation requires distinct conformations of the ATPase domains, the clamp loader spiral...
The elastic dynamic buckling of geometrically imperfect rectangular composite plates under a longitudinal compressive pulse is investigated. Specifically, the effects of fiber orientations of angle-ply laminated panels are studied. Geometric nonlinearities due to large deflections, as well as wave propagation effects due to inplane inertia terms, are included in the analysis. The applied load is...
A naive model of starch gelatinization kinetics was constructed to determine a control parameter of the baking process (i.e. a baking index).Bread dough samples were instantaneously heated at different temperatures (60-90°C) for varying times and then subjected to differential scanning calorimetry to evaluate the extent of starch gelatinization. Calorimetric traces, after smoothing and standardization,...
