The Fate of Organic Phases in Porous Idps and Micrometeorites during Atmospheric Entry: a Pulse-heating Study
Interplanetary dust particles (IDPs) and micrometeorites (MMs) are typically heated at temperatures higher than 500 C for few seconds during their atmospheric entry [1,2]. They have been extensively studied with several techniques for their carbon content and for the nature of their carbonaceous phases [3, 4, 5, 6]. Several kinds of organic molecules have been found in IDPs and MMs: polycyclic ...
متن کاملIon heating resulting from pickup in magnetic reconnection exhausts
[1] The heating of ions downstream of the x-line during magnetic reconnection is explored using full-particle simulations, test particle simulations, and analytic analysis. Large-scale particle simulations reveal that the ion temperature increases sharply across the boundary layer that separates the upstream plasma from the Alfvénic outflow. This boundary layer, however, does not take the form ...
متن کاملMacular changes resulting from papilloedema.
Six cases are presented with macular changes in association with papilloedema; 4 suffered permanent visual loss. The present paper emphasises this previously infrequent finding and discusses the haemodynamic and mechanical factors responsible. The macular changes consisted of haemorrhages situated in front, within, or behind the retina, and occasionally the results of neovascular membrane forma...
متن کاملElectrolyte Changes Resulting from Injury
THE importance of adequate fluid and electrolyte therapy is now readily appreciated, and the principles underlying the correction of deficiencies are well established. Everywhere the importance of base conservation by the body is accepted, and measures taken to correct any deficiency of base substance are rigorously applied. We appreciate clearly the difference between a true water deficiency a...
متن کاملHeterosis resulting from degenerative changes.
ERITABLE variations in inbred strains of maize occur infrequently. All H the mutations BO far found either do not increase the amount of growth and productiveness or clearly reduce the plants in some degree (JONES 1924, 193a, 1944; SINGLETON 1943). Several changes have been noted recently and reported in a preliminary way (JONES 1944) which reduce the vigor of the inbred plants but which increa...
