For a semi-Pfa an set, i.e., a real semianalytic set de ned by equations and inequalities between Pfa an functions in an open domain G, the frontier and closure in G are represented as semi-Pfa an sets. The complexity of this representation is estimated in terms of the complexity of the original set. Introduction. Pfa an functions introduced by Khovanskii [K] are analytic functions satisfying a...

This paper presents the results of continuous monitoring of 11 pollution indicators of municipal wastewater that were discharged into the natural recipient (the sea) at three locations in the Split area during four years (2006-2009). Experimental data were analyzed by basic statistical methods for determination of mean and median values, standard deviations, minimal and maximal value of the mea...

Plasmodium falciparum alanine M1-aminopeptidase (PfA-M1) is a validated target for anti-malarial drug development. Presence of significant similarity between PfA-M1 and human M1-aminopeptidases, particularly within regions of enzyme active site leads to problem of non-specificity and off-target binding for known aminopeptidase inhibitors. Molecular docking based in silico screening approach for...

This paper presents the first stage in the development of a Physics Goal Orientation survey a survey identifying students’ beliefs about how to be successful in physics studies. The analysis method used is exploratory factor analysis, a powerful statistical method requiring subjective decision making. Instead of taking a ‘black box’ approach, which can easily lead researchers to draw incorrect ...

Projective mapping and sorting tasks—often called “Holistic” methods—are methods that directly obtain similarity measurements between products by asking participants (who could be novices, trained assessors, or experts, adults or children) to provide a global evaluation of a set of products of interest. In projective mapping, each participant is asked to place products on a sheet of paper in su...

The aim of this study is to explore the characteristics of innovative personality among teachers in Malaysia. Samples of the research were randomly selected among secondary school teachers in three districts in Malaysia. Research instrument was self-developed by the researchers based on interviews carried out with some resource persons who are both experts and authoritative in their fields, as ...

Sequential Factor Analysis (seqFA) is presented here as an enhanced alternative to multivariate factorial techniques including robust and classical Factor Analysis (FA) or Principal Component Analysis (PCA). A geochemical data set of 145 sediment samples from very heterogeneous, mainly riverine, deposits of the Rhine-Meuse delta (The Netherlands) analyzed for 27 bulk parameters was used as a te...

A number of research works in finance rely on the selection of factors affecting the behaviour of one or more underlying variables. Factor Analysis (FA) and Principal Components Analysis (PCA) are statistical tools allowing for selecting a reduced number of factors explaining the variations of a set of variables. Of particular interest has been the study of the factors explaining the behaviour ...

This paper addresses the problem of hedging a portfolio of fixed-income cashflows. We first briefly review the traditional duration hedging method, which is heavily used by practitioners. That approach is based on a series of very restrictive and simplistic assumptions, including the assumptions of a small and parallel shift in the yield curve. We know however that large variations can affect t...

UNLABELLED The common diagnostic methods to know primary hemostasis have been classified as invasive, depending on the operator, difficult to reproduce and at times not very reliable. Thus, different systems have been proposed to assess bleeding time, one of them being the PFA-100 device, which we present in this paper. OBJECTIVE Compare specificity between the traditional Ivy method with the...
