13. ORBITALS IN GENERAL CHEMISTRY, PART II: MATHEMATICAL REALITIES
In Part II of a three-part series, we discuss two factors absent from textbooks of general chemistry that are important in a discussion of teaching orbitals. First, atomic orbitals are shown systematically to comprise algebraic formulae in coordinates of not one but four sets (spherical polar, paraboloidal, ellipsoidal, spheroconical coordinates). Each formu

15. Mathematical Analysis and Improvement of the Maximum Spatial Eigenfilter for Direction of Arrival Estimation
Abstract Maximum spatial eigenfiltering improves the accuracy of maximum likelihood direction-of-arrival estimators for closely-spaced signal sources but may interchangeably attenuate widely-spaced signal sources, producing a severe performance degradation. Although this behavior has been observed experimentally, it still lacks a mathematical explanation. In

16. REFERENTIAL USES OF ARABIC NUMERALS
Abstract Is the debate over the existence of numbers unsolvable? Mario Gómez-Torrente presents a novel proposal to unclog the old discussion between the realist and the anti-realist about numbers. In this paper, the strategy is outlined, highlighting its results and showing how they determine the desiderata for a satisfactory theory of the reference of Arab

17. NATURAL KINDS AND OUR SEMANTIC INTUITIONS ALONG THE ROAD
Abstract This is a comment on Gómez-Torrente’s approach to natural kinds and natural kind terms. Here I will focus on his concerns related to the arbitrariness argument and his attempt to formulate a reply to it that maintains most (if not all) of the “Kripke-Putnam orthodoxy” when it comes to the reference-fixing of such terms. Gómez-Torrente conclu

18. A Simple Approach to Analyze Sugar Nectar Composition in Flowers Using Capillary Electrophoresis and Enzymatic Assays
Despite the obvious importance of nectar, the composition of this solution remains surprisingly understudied to most of the flowers. Here we describe a simple, low-cost, and reliable methodology to analyze the three main sugars present in 210 nectar samples of Christmas Bellflowers using capillary electrophoresis (CE) and enzymatic assays. CE separation (-16

19. The effect of facial expression on emotional contagion and product evaluation in print advertising
Abstract Purpose The purpose of this paper is to investigate the emotional contagion theory in print ads, and expand the literature of smiling to different type of smiles and gender congruency. Emotional contagion happens when an emotion is transferred from a sender to a receiver by the synchronization of emotions from the emitter. Drawing on emotional cont

20. MOORE’S PARADOX AND THE LOGIC OF BELIEF
Abstract Moore’s Paradox is a test case for any formal theory of belief. In Knowledge and Belief, Hintikka developed a multimodal logic for statements that express sentences containing the epistemic notions of knowledge and belief. His account purports to offer an explanation of the paradox. In this paper I argue that Hintikka’s interpretation of one of

22. EXPERIMENTO DIDÁTICO DE QUIMIOMETRIA PARA CLASSIFICAÇÃO DE ÓLEOS VEGETAIS COMESTÍVEIS POR ESPECTROSCOPIA NO INFRAVERMELHO MÉDIO COMBINADO COM ANÁLISE DISCRIMINANTE POR MÍNIMOS QUADRADOS PARCIAIS: UM TUTORIAL, PARTE V
A teaching experiment on supervised pattern recognition in chemometrics was proposed in this tutorial to introduce partial least squares discriminant analysis (PLS-DA). A new approach of the experiment published in the first tutorial of this series was revisited and employed to the classification of edible vegetable oils. The spectra of olive, canola, soybea

23. Sobre a relevância filosófica do argumento do milagre
Resumo: Neste artigo, argumentamos a favor de uma versão sofisticada do realismo científico, tendo como eixo norteador a análise do desempenho do que consideramos ser o seu elemento de defesa estratégico: o “argumento do milagre”. O realismo científico é a perspectiva comprometida com as nossas melhores teorias científicas, isto é, com a existên

24. ¿Una mercancía “como cualquier otra”? Reexaminando la determinación del valor de la fuerza de trabajo
Abstract This article addresses the process of production of labour power with a view to re-examining Marx’s stance on the determination of the value of this ‘peculiar commodity’. In order to do so, the article critically reviews the main contributions which have called into question the Marxian analysis. It also offers an alternative argument that dev
