On the existence of fractal strings whose set of dimensions of fractality is not perfect

In this paper we give an example of a nonlattice self-similar fractal string such that the set of real parts of their complex dimensions has an isolated point. This proves that, in general, the set of dimensions of fractality of a fractal string is not a perfect set.

On the existence of exponential polynomials with prefixed gaps

This paper shows that the conjecture of Lapidus and Van Frankenhuysen on the set of dimensions of fractality associated with a nonlattice fractal string is true in the important special case of a generic nonlattice self-similar string, but in general is false. The proof and the counterexample of this have been given by virtue of a result on exponential polynomials P(z), with real frequencies linearly independent over the rationals, that establishes a bound for the number of gaps of RP, the closure of the set of the real projections of its zeros, and the reason for which these gaps are produced.

Prevalência de lesões musculo-esqueléticas em profissionais de artes musicais

Enquadramento: As lesões músculo-esqueléticas relacionadas com o trabalho apresentam-se atualmente como um crescente flagelo e a profissão de músico é uma atividade predisponente para a ocorrência dessas lesões, exigindo uma atenção especial dos profissionais de saúde para identificar e controlar os fatores de risco. Objetivos: O presente estudo pretende identificar a prevalência das perturbações músculo-esqueléticas nos músicos profissionais praticantes de Cordofones beliscados e analisar a sua relação com as variáveis sociodemográficas, estado de saúde e características da prática instrumental. Métodos: Trata-se de um estudo não experimental, transversal, descritivo-correlacional e de caráter quantitativo, que envolveu 70 músicos portugueses praticantes de cordofones beliscados, residentes em Viseu, Porto e Lisboa, com idades compreendidas entre 18 e 55 anos. Foi realizado com recurso ao uso de um questionário que avalia as variáveis sociodemográficas, as clínicas e as relacionadas com a prática musical e para avaliação das perturbações musculoesqueléticas utilizámos o “Questionário Nórdico Músculo-Esquelético”. Resultados: Dos músicos estudados 70,0% referem sentir perturbações músculo-esqueléticas como dor/formigueiro/dormência nos últimos 12 meses, tendo estes ocorrido sobretudo nos punhos/mãos (68.6%), ombros (54.3%), pescoço e região lombar (44.3%). Observámos que são vários os fatores risco das perturbações musculoesqueléticas como a idade avançada, um Índice de Massa Corporal mais elevado, o consumo de bebidas alcoólicas, não praticar atividade física, o excesso de espetáculos, a postura adotada, instrumentos mais pesados e tocar sem pausas. Conclusões: O nosso estudo reforça a ideia de que as perturbações músculo-esqueléticas estão presentes nos músicos portugueses e que a sua origem está relacionada com características individuais, estado de saúde e exigências da prática instrumental. Cabe então ao Enfermeiro de Reabilitação criar estratégias preventivas, para evitar que os fatores de risco acrescidos causem ou aumentem as já instaladas lesões músculo-esqueléticas nos músicos, promovendo uma carreira longa e saudável. Palavras-chave: Músicos; Lesões musculoesqueléticas; Fatores de risco; Enfermagem de Reabilitação.

Les caractères musicaux au sein d'une démarche artistique dramatique : exploration des indices acoustiques jouant un rôle dans l'évocation des états affectifs en musique.

Cette thèse de doctorat en composition comprend deux projets de nature différente et complémentaire : (1) un projet de recherche théorique sur la communication des caractères musicaux; (2) un projet artistique s'articulant autour de la composition de trois pièces : L'homme à deux têtes - opéra de chambre, Un instant dans l'esprit de Lovecraft - pour clarinette solo, orchestre à cordes et percussions, et Balade ornithologique - pour orchestre à vents. La conception de la musique comme un moyen de communication est à l'origine de cette recherche théorique qui est motivée par un désir de compréhension des stratégies d'expressions des émotions en musique, à partir du point de vue du compositeur. Cette thèse aborde les modèles de communication, le concept de personnage virtuel et la théorie de la contagion des humeurs. Par la suite, nous détaillerons les indices acoustiques menant à la perception des caractères musicaux. Toutes ces notions sont illustrées et explorées par la composition de miniature ayant un caractère bien ciblé. Finalement, nous proposons un système d'analyse musical des caractères et des émotions qui est appliqué à l'analyse de sections des pièces composées au cours de ce projet de doctorat. Ce dernier chapitre met en lumière les stratégies utilisées pour créer un discours dramatique tout en exposant l'évocation de différents caractères musicaux.

(Table 2) Revised stacked record on magnetic susceptibility of ODP Site 162-984 sediments

Magnetic field and susceptibility data were collected using the geological high-resolution magnetometer tool string (GHMT) at three sites during Ocean Drilling Program Leg 162. Postcruise processing of the magnetic field data yielded a polarity stratigraphy for Holes 986C and 987E. A magnetic susceptibility record was measured at Hole 984B. Detailed analysis of the core and log susceptibility records at Hole 984B yielded an empirical tool resolution of the susceptibility measurement tool (SUMT) of 53 cm. At Site 984, where sedimentation rates were typically >10 cm/k.y., this gave a resolution of at least ~5000 yr. This data report summarizes the GHMT postcruise processing, method of interpretation, and analysis of the SUMT resolution.

(Table 1) Summary of basalt unit thickness, vesicularity, number of flow units, and average porosity at ODP Site 135-839

An inflatable drill-string packer was used at Site 839 to measure the bulk in-situ permeability within basalts cored in Hole 839B. The packer was inflated at two depths, 398.2 and 326.9 mbsf; all on-board information indicated that the packer mechanically closed off the borehole, although apparently the packer hydraulically sealed the borehole only at 398.2 mbsf. Two pulse tests were run at each depth, two constant-rate injection tests were run at the first set, and four were run at the second. Of these, only the constant-rate injection tests at the first set yielded a permeability, calculated as ranging from 1 to 5 * 10**-12 m**2. Pulse tests and constant-rate injection tests for the second set did not yield valid data. The measured permeability is an upper limit; if the packer leaked during the experiments, the basalt would be less permeable. In comparison, permeabilities measured at other Deep Sea Drilling Project and Ocean Drilling Program sites in pillow basalts and flows similar to those measured in Hole 839B are mainly about 10**-13 to 10**-14 m**2. Thus, if our results are valid, the basalts at Site 839 are more permeable than ocean-floor basalts investigated elsewhere. Based on other supporting evidence, we consider these results to be a valid measure of the permeability of the basalts. Temperature data and the geochemical and geotechnical properties of the drilled sediments all indicate that the site is strongly affected by fluid flow. The heat flow is very much less than expected in young oceanic basalts, probably a result of rapid fluid circulation through the crust. The geochemistry of pore fluids is similar to that of seawater, indicating seawater flow through the sediments, and sediments are uniformly underconsolidated for their burial depth, again indicating probable fluid flow. The basalts are highly vesicular. However, the vesicularity can only account for part of the average porosity measured on the neutron porosity well log; the remainder of the measured porosity is likely present as voids and fractures within and between thin-bedded basalts. Core samples, together with porosity, density, and resistivity well-log data show locations where the basalt section is thin bedded and probably has from 15% to 35% void and fracture porosity. Thus, the measured permeability seems reasonable with respect to the high measured porosity. Much of the fluid flow at Site 839 could be directed through highly porous and permeable zones within and between the basalt flows and in the sediment layer just above the basalt. Thus, the permeability measurements give an indication of where and how fluid flow may occur within the oceanic crust of the Lau Basin.

Polarity chron boundaries and interval sedimentation rates of ODP Leg 162 sites

Magnetic polarity stratigraphies for Sites 980-984 are based on shipboard measurements from the pass-through magnetometer after alternating field (AF) demagnetization at a peak field of 25 mT and shore-based stepwise AF demagnetization of discrete samples. The characteristic magnetization component was determined after AF demagnetization removed the steep downward drill-string-related magnetic overprint. Peak AF fields in the 20-30 mT range were required to resolve the component, carried by magnetite, that was used to produce unambiguous Pliocene-Pleistocene magnetic stratigraphies at all five sites. At Sites 980 and 983, magnetic stratigraphies were resolved to the base of the recovered advanced hydraulic piston corer (APC) section, which lies in the Matuyama Chron (1r.2r) and Olduvai Subchron (2n), respectively. At Sites 981 and 982, magnetization intensities decrease sharply in the normal polarity zone corresponding to the Gauss Chron (2An), and magnetic stratigraphies below this level could not be resolved. At Site 984, the resolution of magnetic stratigraphy was curtailed at ~250 meters below seafloor (Olduvai Subchron) by core deformation at the base of the APC section and in the underlying extended core barrel section. As the magnetic stratigraphies at all four sites are unequivocal, polarity chron interpretations can be made without aid from the biostratigraphy. Mean sedimentation rates within polarity chrons have been calculated and Pliocene-Pleistocene biomagnetostratigraphic correlations tested.
