Shapes and motions of polysaccharide chains

چکیده

Computer-based molecular modeling of single stranded polysaccharide chains is capable of a quantitative description of the polymer chain dimensions in dilute aqueous solution. The influence of glycosidic linkage position and stereochemistry on the local chain trajectory is now well understood. Some illustrative results of modeling of this sort are reported here. More recent efforts to understand the possible influence of glycosidic linkage type on the dynamics of polysaccharide conformational change are also described.

Stress Analysis of Flight Vehicles under Flight Conditions

A method is presented for the stress analysis of flight vehicles under different flight conditions including gust and control surface deflection (or maneuver) using the governing equations of rigid-body motions and elastic deformations. The Lagrangian approach is used to derive the governing equations of motions. For this purpose, the basic equations of motions are derived in terms of potential...

Impact of cell shape and chain formation on nutrient acquisition by marine diatoms

Diatoms have evolved a multitude of morphologics, including highly elongated cells and cell chains. Elongation and chain formation have many possible functions, such as grazing protecticn or effects on sinking. Here, a model of diffusive and advective nutrient transport is used to predict impacts of cell shape and chain length on potential nutrient supply and uptake in a turbulent environment. ...
