In this paper, we derive analytical expressions for mass and stiffness functions of transversely vibrating clamped-clamped non-uniform beams under no axial loads, which are isospectral to a given uniform axially loaded beam. Examples of such axially loaded beams are beam columns (compressive axial load) and piano strings (tensile axial load). The Barcilon-Gottlieb transformation is invoked to transform the non-uniform beam equation into the axially loaded uniform beam equation. The coupled ODEs involved in this transformation are solved for two specific cases (pq (z) = k (0) and q = q (0)), and analytical solutions for mass and stiffness are obtained. Examples of beams having a rectangular cross section are shown as a practical application of the analysis. Some non-uniform beams are found whose frequencies are known exactly since uniform axially loaded beams with clamped ends have closed-form solutions. In addition, we show that the tension required in a stiff piano string with hinged ends can be adjusted by changing the mass and stiffness functions of a stiff string, retaining its natural frequencies.

Resumen: El compositor realiza un análisis de su Sonatinina, miniatura para piano, la cual consiste en una extrema condensación de elementos delos cuatro movimientos de la forma sonata tradicional. Una aproximación analítica se basa en describir e interrelacionar estructuras interválicas, pero otro tipo de análisis estudia las connotaciones o referencias a la tradición y al repertorio existente, ya sean citas de obras concretas o bien citas de estilo. La obra Sonatinina es, en su totalidad, una alusión a un arquetipo formal.

Early illustrated book about fish, fishing and fisheries by one of the preeminent scientific investigators of the French enlightenment. This work deals extensively with the species of fish found in Europe and beyond, their habits and habitats, techniques and equipment used in fishing and fish processing, and many other aspects of these endeavours. Roughly 185 engraved plates illustrate the text. The scans for this version come from 3 volumes bound in two parts in folio.

La pêche, y compris l'aquaculture, apporte une contribution fondamentale à l'alimentation, à l'emploi, aux loisirs, au commerce et au bien-être économique des populations du monde entier, qu'il s'agisse des générations présentes ou futures, et devrait, par conséquent, être conduite de manière responsable. Le présent Code définit des principes et des normes internationales de comportement pour garantir des pratiques responsables en vue d'assurer effectivement la conservation, la gestion et le développement des ressources bioaquatiques, dans le respect des écosystèmes et de la biodiversité. Le Code reconnaît l'importance nutritionnelle, économique, sociale, environnementale et culturelle de la pêche et les intérêts de tous ceux qui sont concernés par ce secteur. Le Code prend en considération les caractéristiques biologiques des ressources et de leur environnement, ainsi que les intérêts des consommateurs et autres utilisateurs. Les Etats et tous ceux impliqués dans le secteur de la pêche sont encouragés à appliquer ce Code de manière effective. (PDF contains 53 pages)

During hydrographic and plankton studies carried out since 1960 in the coastal zone between the Ebro and Castellon (western Mediterranean), data has been collected which confirms the importance of ciliates in the composition and activity of the plankton. The ciliates in 413 samples of 100 ml of water were counted, having been examined with the Utermohl microscope after sedimentation. The samples studied were distributed according to the density of their population. subject for study. The author concludes that recognition of the role of ciliates as an important link in the food chain of the sea would simplify the interpretation of certain problems posed by the nutrition of certain groups of planktonic animals.
