GUITAR ARRANGEMENTS OF SELECTED DANZAS OF JUAN F. ACOSTA, WITH NEW CONSIDERATIONS OF HIS MUSIC AND MUSICAL LIFE

Juan Francisco Acosta (1890-1968) was a prolific composer, band conductor, and educator from Puerto Rico who created 1,256 original compositions. Even though his activities and influence were integral to the musical life of Puerto Rico in the twentieth century, many details of his life and works remain unknown. This project centers on Acosta’s contribution to the Puerto Rican tradition of the danza—a dance-based genre originating in the nineteenth century—through the study and arrangement of five of Acosta\u27s danzas. Although Acosta composed most danzas for piano, he adapted them for performances by the municipal bands that he led in various towns. This practice of modifying his works for different instruments, as well as the importance of the guitar in Latin America, underpins the author’s choice to arrange his piano music for varied types of guitar combinations, including solo, duo, trio, and quartet. The five works are Bajo la sombra de un pino, Mercedes, Eres una santa, Dulce María, and In memoriam. The guitar arrangements of these five danzas are preceded by important information on the composer within the Puerto Rican music world, with emphasis on the intersections of the band and danza traditions. To enhance the study of these works, this document discusses basic stylistic features, including a comparison of forms, rhythms, and dance characters, and relates Acosta\u27s treatment of the danza puertorriqueña to approaches of his Puerto Rican contemporaries. This document also includes performance guidelines to introduce Acosta\u27s danza style to student and professional players. Based on primary biographical and musical sources, this study presents a foundation for a clearer understanding of the life and works of Acosta upon which further research, analysis, and criticism can be conducted. The arrangements offer a fresh look at new guitar repertoire using the peculiarities of rhythms and traditions of Puerto Rican and Carribean heritage. The arrangements also serve a pedagogical purpose by adding to the existing repertoire of ensemble music for the classical guitar

Simple permutations with order 4n+24n + 2. Part I

The problem of genealogy of permutations has been solved partially by Stefan (odd order) and Acosta-Hum\'anez & Bernhardt (power of two). It is well known that Sharkovskii's theorem shows the relationship between the cardinal of the set of periodic points of a continuous map, but simple permutations will show the behavior of those periodic points. This paper studies the structure of permutations of mixed order $4n+2$, its properties and a way to describe its genealogy by using Pasting and Reversing.Comment: 17 page

An integrated model for computer assisted diagnosis, treatment and design of insoles for the diabetic foot

The incidence of diabetes has increased significantly in recent decades. In Germany, there is an estimate of three million diabetics and this number is growing at a rate of about 2 percent per year. In the U.S.A., the American Diabetes Association estimates that thirteen million people suffer from this condition, representing 5.2 percent of the entire population and every year, some 35 thousand patients have a lower limb amputated. In Latin America, it has been reported that the prevalence of diabetes is of the order of 14 to 20 percent, according to a research conducted by the WHO's Ad Hoc Diabetes Reporting Group. In Colombia, a study by Ashner et al concludes that the prevalence is 7 percent in both sexes

Nutritional factors affecting serum phenylalanine concentration during pregnancy for identical twin mothers with phenylketonuria

The effect of energy, protein, fat, and phenylalanine on serum phenylalanine concentrations during pregnancy for a set of identical twins with phenylketonuria (PKU) was examined. Blood samples were collected one to two times per week. The subjects completed a 3-d food record prior to each blood collection. The effect of the factors on serum phenylalanine levels was evaluated statistically using time-series analysis. Dietary intakes of the nutrients evaluated were similar for the subjects. For one subject, there were highly significant effects of energy, protein, and fat on serum phenylalanine levels. In contrast, these nutrients had no significant effect on serum phenylalanine for the other subject. Dietary phenylalanine had no significant effect on serum phenylalanine for either twin. Conclusions: There was no effect of phenylalanine intake and no consistent effect of energy, protein, or fat on serum phenylalanine. Other dietary or environmental factors or a combination of factors may impact serum phenylalanine levels of pregnant women with PKU

Search for excited electrons through γγ\gamma\gamma scattering

We study the potential of $\gamma \gamma$ option of future high energy linear $e^{+}e^{-}$ colliders to search for excited electrons with spin-1/2. We calculate single production cross sections, give the angular distributions and $f-m^*$ contour plots for $\sqrt{s}=0.5$ TeV and $\sqrt{s}=3$ TeV both using the standard (tree level) couplings and anomal couplings.Comment: 10 pages, 6 figures, accepted for publication in PR
