Understanding the mechanical properties of DNA such as their bending and torsional rigidity can provide a great deal of insight about the factors that determine the folding of DNA during the cell cycle. These quantities have been obtained from bulk experiments using light scattering, equilibrium sedimentation, DNA cyclization, etc. Determination of the elastic properties of DNA with these methods is indirect, via a theoretical framework relating the observable quantities to the elastic parameters of the molecules. Moreover, the results represent an ensemble average over all accessible configurations of the molecule, with small contribution from stretched un-likely states.We have carried a systematic study of the elastic properties of single DNA molecules. Single DNA molecules were chemically attached by one end to a glass surface and by their other end to a magnetic bead. Equilibrium positions of the beads are observed in an optical microscope while the beads are acted on by known magnetic and hydrodynamic forces.

A precise method for the determination of the increment of the  basal area using the PressIer bore. Refering to  previous research showing that the basal area of the corsica pine could be  characterized by an ellips, we present in this paper a precise method for the  determination of the increment of the basal area. In this method we determine  the direction of the maximum diameter, we measure this diameter and we take a  core in one of the points of tangency of the caliper with the measured tree.  The determination of the diameter perpendicular to the maximum diameter  finishes the work wich is to be done in the forest. From the classical  measurements effectuated on the core and from the measured diameters we can  then determine the form (V) and the excentricity (e). Substituting these two  parameters in the formula 2 or 2', we can also calculate the error of a  radius measured on the core with respect to the representative radius, This  error with them allow us to correct the measured value of the minimum or the  maximum radius and we will be able to do a precise determination of the  increment.
