Low-stress transfer bonding using floatation

A novel method for transferring thin, large-area polymer layers from a mould and its subsequent bonding to a destination substrate is presented here. Buoyancy is used for transfer via floatation to allow the release of internal stress in the polymer and to avoid induced strain. Additionally, floatation leads to wrinkle-free contact between the polymer layer and its destination substrate, an imp...

Capillarity and Archimedes’ Principle of Floatation

We consider some of the complications that arise in attempting to generalize a version of Archimedes’ principle of floatation to account for capillary effects. The main result provides a means to relate the floating position (depth in the liquid) of a symmetrically floating sphere in terms of readily observable geometric quantities. A similar result is obtained for an idealized case correspondi...

Serum lipoprotein measurement--liquid chromatography and sequential floatation (ultracentrifugation) compared.

An HPLC method [J. Biochem. (Tokyo) 91:1381, 1982] was used for evaluating serum lipoproteins, with on-line monitoring of either cholesterol or phospholipids. Five well-distinguished lipoprotein fractions were observed, based on their particle sizes. Serum of 15 normal persons, 12 subjects with various types of hyperlipidemia, 20 patients with various liver diseases, and two cases of familial L...

Storage Tank Design

A calculus problem arising in the operation of a storage tank for a chemical processing plant is described. Constructing an appropriate gauge for the storage tank requires computing the volume of water residing inside a tilted cylindrical pipe. The following calculus problem arose in the engineering design of a storage tank facility, and is possibly more interesting and challenging for students...
