Acidization--V : The prediction of the movement of acid and permeability fronts in sandstone
(Elsevier, 1976)
A new model has been developed which describes the acidization of sandstone cores. The results show that the reaction of hydrofloric acid with the dissolvable minerals occurs in a narrow zone which moves as a reaction front ...
Strain-induced crystallization II. Subsequent fibrillar-to-lamellar transformation Previously presented at the ACS Symposium on Fiber and Yarn Processing Philadelphia (April 9, 1975)
(Society of Plastics Engineers, Inc.Wiley Periodiocals, Inc., 1976-03)
Part II discusses numerous examples of a morphological fibrillar-to-lamellar transformation that has reportedly been observed in stretched polymers upon additional thermal treatment (or TIC), Stretched polymers containing ...
Laminar free-surface flow into a vertical cylinder
(Elsevier, 1975-03)
This study concerns the unsteady free-surface flow of a Newtonian fluid issuing vertically upwards from a tube in the base of a vertical cylindrical cavity. Experimental and numerical results are presented and discussed.The ...

Current concepts of morphology of amorphous polymers-- II. Degree of local order and overall chain conformation
(Elsevier, 1979)
After a brief discussion on our earlier electron microscopyrresults of amorphous polymers and the results obtained by others in recent years from small angle neutron scattering and optical anisotropy measurements, it is ...
Strain-induced crystallization, Part IV: Induction time analysis
(Society of Plastics Engineers, Inc.Wiley Periodiocals, Inc., 1979-05)
The empirical equation, 1/t i = Ae Ei/RT , which expresses the exponential dependence of the reciprocal of crystallization induction time, t i , has been analyzed and shown to be equivalent to the nucleation rate ...
