Delayed loading regions

The trap is loaded in a time of a few seconds, and after a preselected delay its contents are dumped into the resonator region by lowering the field of one of the pinch solenoids. The signal from the hyperfine resonance detector provides a measure of the total number of atoms N in the trap. The stored atoms decay by dipole relaxation (described below) with a rate that is proportional to the density n. From values of N and n one can find the effective volume of the trap. The effective volume depends on the field geometry and the temperature. This roundabout route is... 

Wn et al. demonstrates that a lipid-polymer hybrid drug delivery systan loaded with doxorubicin is effective for tnmor treatment in a well-established animal model. Tumor growth delay and tnmor necrosis were observed in tnmors treated with the lipid-polymer hybrid formulation of doxorubicin. It was fonnd that these lipid-polymer hybrids carrying anticancer agents were useful for loco-regional treatment of breast cancer with an improved therapeutic index. 

In contrast, when loaded with a sufficiently thick film, a TSM resonator functions as a rheological probe of the properties of surface-attached species. An acoustically thick film is one whose combination of thickness and shear stiffness is such that the acoustic wave significantly deforms it. Consequently, displacement of the outer regions of the film exhibits a phase delay with respect to displacement of the underlying resonator. Multilayer adsorbates may behave in this manner if they are either intrinsically soft or are plasticized by the permeation of a solvent or other small molecules. This situation is more complicated and it is only recently that the theoretical aspects have been treated in quantitative fashion for fluid-immersed films. Accordingly, this case is described subsequently to the simpler gravimetric case and in greater detail. 

Generally the third result is technologically desirable. In order to define the region of permissible loads a study of the delayed failure, i.e. of the time-dependent strength, is indispensable.
