Neutralization tests of a mN FEEP thruster

32nd Joint Propulsion Conference and Exhibit, 1996
Neutralization of the ion beam produced by a FEEP thruster is in principle a task similar to the well-known problem of neutralizing a traditional ion rocket.On the other hand, the neutralization of a small, micronewton thrust level FEEP poses several practical problems.

Neutralization Tests with Certain Neurotropic Viruses

The Journal of Immunology, 1944
Abstract The relative lack of sensitivity of intracerebral virus-neutralization tests in mice, and their consequent limitations when applied to the investigation of certain epidemiologic or immunologic problems, is generally recognized. Inasmuch as the ability to detect or quantitate neutralizing antibodies in a serum is ...

Three “Neutral” Loading Tests

Journal of Applied Mechanics, 1956
Abstract Three tests have been carried out using hollow tubes of alpha brass subjected to combined torsion and internal pressure. An initial torque was applied sufficient to cause plastic deformation, and then the torque was decreased and the internal pressure increased to keep the octahedral shear stress constant in two tests and the ...

The Neutralization Test in Lymphogranuloma Venereum

Journal of Infectious Diseases, 1940
The neutralization test has proven a highly important aid in the recognition and epidemiological study of numerous virus diseases. In lymphogranuloma venereum as well, this test should be distinctly valuable, especially in those cases where it is not possible or practicable to perform the Frei test or where there is anergy or a doubtful skin reaction ...

Test of Selection and Neutrality in Natural Populations

Nature, 1973
MORE than a century after the publication of Darwin's Origin of Species, the question of the relative contribution of selected and nonselected (“neutral”) genetic variation to evolution is still unresolved1,2.

Testing neutralization of adversary aircraft

Proceedings IEEE 32nd Annual 1998 International Carnahan Conference on Security Technology (Cat. No.98CH36209), 2002
This paper describes the technological and programmatic requirements to test adversary helicopter neutralization capabilities for facility physical security (counter-terrorism) planning. Specifically, the paper reports findings from anti-aircraft testing using advanced laser engagement simulation equipment.

A test of the unified neutral theory of biodiversity

Nature, 2003
One of the fundamental questions of ecology is what controls biodiversity. Recent theory suggests that biodiversity is controlled predominantly by neutral drift of species abundances. This theory has generated considerable controversy, because it claims that many mechanisms that have long been studied by ecologists (such as niches) have little ...

Interpreters at War: Testing Boundaries of Neutrality

2019
This chapter aims to explore the distinctive attitudes and narratives of interpreters in conflict zones, whose role is no longer seen as a fixed notion as they adjust their positioning along a spectrum from invisibility to advocacy. In this context, we will explore the extent to which institutional and professional boundaries have been challenged, and ...
