Quantification of the carbonaceous matter origin in submicron marine aerosol by 13C and 14C isotope analysis
D. Ceburnis,A. Garbaras,S. Szidat,M. Rinaldi
Atmospheric Chemistry and Physics (ACP) & Discussions (ACPD) , 2011, DOI: 10.5194/acp-11-8593-2011
Abstract: Dual carbon isotope analysis of marine aerosol samples has been performed for the first time demonstrating a potential in organic matter apportionment between three principal sources: marine, terrestrial (non-fossil) and fossil fuel due to unique isotopic signatures. The results presented here, utilising combinations of dual carbon isotope analysis, provides conclusive evidence of a dominant biogenic organic fraction to organic aerosol over biologically active oceans. In particular, the NE Atlantic, which is also subjected to notable anthropogenic influences via pollution transport processes, was found to contain 80 % organic aerosol matter of biogenic origin directly linked to plankton emissions. The remaining carbonaceous aerosol was of terrestrial origin. By contrast, for polluted air advected out from Europe into the NE Atlantic, the source apportionment is 30 % marine biogenic, 40 % fossil fuel, and 30 % continental non-fossil fuel. The dominant marine organic aerosol source in the atmosphere has significant implications for climate change feedback processes.
Quantification of Nonclassicality  [PDF]
C. Gehrke,J. Sperling,W. Vogel
Physics , 2009,
Abstract: To quantify single mode nonclassicality, we start from an operational approach. A positive semi-definite observable is introduced to describe a measurement setup. The quantification is based on the negativity of the normally ordered version of this observable. Perfect operational quantumness corresponds to the quantum-noise-free measurement of the chosen observable. Surprisingly, even moderately squeezed states may exhibit perfect quantumness for a properly designed measurement. The quantification is also considered from an axiomatic viewpoint, based on the algebraic structure of the quantum states and the quantum superposition principle. Basic conclusions from both approaches are consistent with this fundamental principle of the quantum world.
Quantification of AS and AR  [cached]
Mehta Yatin,Singh Rajni
Annals of Cardiac Anaesthesia , 2009,
Abstract: Trans-esophageal echocardiography (TEE) is routinely used in valvular surgery in most institutions. The popularity of TEE stems from the fact that it can supplement or confirm information gained from other methods of evaluation or make completely independant diagnoses. Quantitative and qualitative assessment permits informed decisions regarding surgical intervention, type of intervention, correction of inadequate surgical repair and re-operation for complications. This review summarizes the various methods for quantification of aortic regurgitation and stenosis on TEE. The application of Doppler echo (pulsed wave, continuous wave and color) with two-dimensional echo allows the complete evaluation of AV lesions.

Revista Brasileira de Ciências Farmacêuticas , 2003, DOI: 10.1590/S1516-93322003000300014
Abstract: the development and comparison of two analytical methods (hplc and gc) for the quantification of the most common furanoheliangolides from lychnophora is reported in this paper. both methods are sensitive and suitable for quantification of these metabolites.
Quantification In Neurology
Netravati M,Taly AB,Nair KPS
Annals of Indian Academy of Neurology , 2005,
Abstract: There is a distinct shift of emphasis in clinical neurology in the last few decades. A few years ago, it was just sufficient for a clinician to precisely record history, document signs, establish diagnosis and write prescription. In the present context, there has been a significant intrusion of scientific culture in clinical practice. Several criteria have been proposed, refined and redefined to ascertain accurate diagnosis for many neurological disorders. Introduction of the concept of impairment, disability, handicap and quality of life has added new dimension to the measurement of health and disease and neurological disorders are no exception. "Best guess" treatment modalities are no more accepted and evidence based medicine has become an integral component of medical care. Traditional treatments need validation and new therapies require vigorous trials. Thus, proper quantification in neurology has become essential, both in practice and research methodology in neurology. While this aspect is widely acknowledged, there is a limited access to a comprehensive document pertaining to measurements in neurology. This following description is a critical appraisal of various measurements and also provides certain commonly used rating scales/scores in neurological practice.
Training load quantification in triathlon  [cached]
Journal of Human Sport and Exercise , 2011,
Abstract: There are different Indices of Training Stress of varying complexity, to quantification Training load. Examples include the training impulse (TRIMP), the session (RPE), Lucia’s TRIMP or Summated Zone Score. But the triathlon, a sport to be combined where there are interactions between different segments, is a complication when it comes to quantify the training. The aim of this paper is to review current methods of quantification, and to propose a scale to quantify the training load in triathlon simple application.
Convex ordering and quantification of quantumness  [PDF]
J. Sperling,W. Vogel
Physics , 2010, DOI: 10.1088/0031-8949/90/7/074024
Abstract: The characterization of physical systems requires a comprehensive understanding of quantum effects. One aspect is a proper quantification of the strength of such quantum phenomena. Here, a general convex ordering of quantum states will be introduced which is based on the algebraic definition of classical states. This definition resolves the ambiguity of the quantumness quantification using topological distance measures. Classical operations on quantum states will be considered to further generalize the ordering prescription. Our technique can be used for a natural and unambiguous quantification of general quantum properties whose classical reference has a convex structure. We apply this method to typical scenarios in quantum optics and quantum information theory to study measures which are based on the fundamental quantum superposition principle.
Theory of the quantification of the redshifts  [PDF]
Jacques Moret-Bailly
Physics , 2003,
Abstract: The quantification of the redshifts of the lines observed in the spectra of the quasars and the galaxies (the redshifts of their lines have some of the values given by the formula z=a+0.062m where a depends on the object, and m is an integer), the density of the lines, result from a purely spectroscopic effect. The explanation requires only standard spectroscopy, a nearly homogeneous halo of atomic hydrogen, and a magnetic field.
Quantification in ordinary language  [PDF]
Michele Abrusci,Christian Retoré
Mathematics , 2011,
Abstract: We firstly show that the standard interpretation of natural quantification in mathematical logic does not provide a satisfying account of its original richness. In particular, it ignores the difference between generic and distributive readings. We claim that it is due to the use of a set theoretical framework. We therefore propose a proof theoretical treatment in terms of proofs and refutations. Thereafter we apply these ideas to quantifiers that are not first order definable like "the majority of".
Metaontology and the problem of quantification
Man?i? ?eljko
Theoria, Beograd , 2009, DOI: 10.2298/theo0903017m
Abstract: This text is concerned with the latest philosophical discipline - metaontology - which main objective is to examine traditional metaphysics and ontological sentences which it includes, as well as with its main theories pluralism, realism and skepticism. While first two of these theories try to provide more or less acceptable arguments in their favor, and show that quantification is justified, it will be shown that they make crucial mistake by neglecting problem of ontological commitment, which is, basically, main source of all metaphysical issues. I shall try to put forward advantages of skepticism over these rival theories, and why one should embrace it in metaontology.
