Isolated fluid oxygen drop behavior in fluid hydrogen at rocket chamber pressures

- K. Harstad, J. Bellan
- Materials Science
- 1 November 1998

A model has been developed for the behavior of an isolated fluid drop of a single compound immersed into another compound in finite, quiescent surroundings at supercritical conditions. The model is… Expand

An all-pressure fluid drop model applied to a binary mixture: heptane in nitrogen

- K. Harstad, J. Bellan
- Materials Science
- 1 October 2000

The differences between subcritical liquid drop and supercritical fluid drop behavior are shown to be a direct consequence of the length scales near the fluid drop boundary. Under subcritical,… Expand

Changing incidence and delay of testicular cancer in southern Norway (1981-1992).

- E. Hernes, K. Harstad, Fosså
- Medicine
- European urology
- 1996

METHODS
The medical records of 352 patients with newly diagnosed testicular cancer were reviewed. Patients were orchiectomized during three 2-year periods (1981/82, 1986/87, 1991/92) and were… Expand
