+Biogenic amines - formation, action and toxicity-review.
The Journal of the Science of Food and Agriculture, 2020Biogenic amines are organic compounds commonly found in food, plants, animals, as well as microorganisms that are attributed with the production of biogenic amines. They are formed as an effect of a chemical process called decarboxylation of amino acids.

Journal of Operator Theory, 2016
In the late 1980's Marc Rieffel introduced a notion of properness for actions of locally compact groups on C*-algebras which, among other things, allows the construction of generalised fixed-point algebras for such actions. In this paper we give a simple characterisation of Rieffel proper actions and use this to obtain several (counter) examples for ...

In this chapter, we present a concise introduction to the theory of proper and isometric actions. We begin with basic definitions and a quick primer on fiber bundles, leading to the Slice Theorem 3.49 and the Tubular Neighborhood Theorem 3.57. These fundamental results are used throughout the rest of the book; in particular, to establish a strong ...

Proper Actions and a Compactness Condition
Journal of Lie Theory, 1995Let \(X = G/H\) be a homogeneous space, with \(G\) a connected Lie group, \(H\) a closed connected subgroup. The author examines the question whether and when there are closed connected subgroups \(L\) of \(G\) acting properly on \(X\) with compact quotient \(L \backslash X\).

Characterizations of proper actions
Mathematical Proceedings of the Cambridge Philosophical Society, 2004The author considers three definitions of the term ``proper action'' that occur in the literature, namely those due to Bourbaki, Palais and to Baum, Connes and Higson. All of them have in common a property which the author spells out as the definition of a Cartan action. What distinguishes the different notions of proper actions are increasingly strong

Alternative Semantic Representations for Zero-Shot Human Action Recognition
ECML/PKDD, 2017A proper semantic representation for encoding side information is key to the success of zero-shot learning. In this paper, we explore two alternative semantic representations especially for zero-shot human action recognition: textual descriptions of ...

Politics Proper: On Action and Prudence
Ethics, 1979This essay-for want of a more adequate phrase-is about a certain style of political activity: about the manner in which a political actor should engage in politics. We are not telling political actors what specific acts to undertake, or formulating some (inevitably simpleminded) manual of considerations for them to go through.

WEAK PROPER ACTIONS ON SOLVABLE HOMOGENEOUS SPACES
International Journal of Mathematics, 2007Let H and K be closed connected subgroups of a connected, simply connected solvable Lie group G. We define the notion of weak and finite proper action of K on the homogeneous space X = G/H and prove that they are equivalent to the notion of (CI)-action of K on X in the sense of Kobayashi. We show also that the action of K on X is proper if and only if
