Inlet stability and case histories, Part II

Inlets which require frequent channel dredging due to gradual shoaling, exhibit migration, or shoal up during storms, are in general unstable and pose a problem to the engineer. This problem of inlet stability is a complex one, because of the rather large number of variables that go into defining stability. The reference here is to inlets on sandy coasts only, because the absence of sand or similar sedimentary material the problem does not arise. Shell is also found in varying proportions with sand. Some of this is. new, whereas in some areas it is ancient reworked material whose size distribution is close to that of the sand with which it is associated. (PDF has 24 pages.)

Beach monitoring project Sand Key Phase II Beach nourishment program (North Redington Beach and Redington Shores) Post-Nourishment Report Part II Offshore Profiles and Wave Data

This study presents the third post-nourishment survey (January 1989) results for the Sand Key Phase II beach nourishment project carried out in June, 1988. The monitoring program to this beach nourishment project is a joint effort between the University of South Florida and University of Florida. The field surveys include a total of 26 profiles, encompassing approximately 3 miles of shoreline extending from DNR R-96 to R-1ll. The total calculated volume loss of sand in the nourished segment (from R-99G to R-107) between the July 88 and January 89 surveys is 51,113 cubic yards, which is a loss about 9.7 percent of 529,150 cubic yards actually placed in the nourishment project. The total loss of sand computed in the entire survey area is 26,796 cubic yards, which is only 5.1 percent of the sand placed in the nourishment project. It is stressed that a part of these net volume reductions is due to the background erosion and not due to spreading losses induced by the nourishment project. (PDF contains 168 pages.)

Evaluación del rendimiento pesquero potencial de la República Argentina: II. Evaluación por regiones

A limnological and fish survey program was developed in 110 lakes and reservoirs of Argentina during the summers of 1984 to 1987. Lakes and reservoirs were visited once, except for six situated in the Chubut Province that were studied seasonally over the course of two years. The sampling surveys were performed by the "Instituto Nacional de Investigación y Desarrollo Pesquero" and the "Provincia de Chubut". Here we present preliminary results of potential fish yield assessment on a regional basis, using empirical models. (Document contains 11 pages.)

Les crimes des empereurs d'Allemagne, depuis Lothaire I jusqu'à Leopold II, avec cinq gravures

Louis Marie Prudhomm nasceu em Lyon em 1752 e morreu em Paris em 1830. Entre os anos de 1787 e 1789, morando em Paris, publicou um número incalculável de panfletos revolucionários, entre os quais destaca-se ‘Résume des cahiers de doléances des bailliages pour les deputés des trois ordres aux etats géneraux’, em 1789. Pouco antes da queda da Bastilha, publicou ‘Las Revoluciones de Paris’. Em 1799, tornou-se impressor e livreiro. Entre suas inúmeras obras se encontram ‘Les crimes des reines de France’; ‘Les crimes des rois de France’; ‘Les crimes des Papes’; ‘Les crimes des empereurs d'Allemagne’, todas publicadas em 1793; ‘Histoire impartiale des révolutions de France depuis la mort de Louis XV’, publicada entre 1824 e 1825; e ‘Repertoire universel, historique, biographique des femmes célebres’, publicada entre 1826 e 1827. De acordo com a ‘Enciclopédia Universal Ilustrada’, há dúvidas quanto à autoria da obra ‘Les crimes des empereurs d'Allemagne’ aventando-se a possibilidade de o literato e político francês, Louis de La Vicomtérie de Saint-Samson ser seu autor

Coronica general de Espana que recopilaba el maestro Florian de Ocampo, coronista del Rey nuestro senor Don Felipe II

Florian de Ocampo, religioso e escritor espanhol, nasceu em Zamora entre os anos de 1490 e 1499 e morreu na mesma cidade, entre 1555 e 1559. Foi no meado cronista-real, em 1539, cargo que lhe permitiu reunir o material e dar continuidade à obra ‘Coronica general de Espana’ que já havia iniciado por conta própria. Continuada por Ambrósio de Morales a partir do volume três desta coleção, o titulo da obra é alterado nos volumes nove e dez para ‘Livro de las antiguedades de las ciudades de Espana’. Ambrósio de Morales, historiador espanhol nasceu em 1513 e morreu em 1591, na cidade de Córdoba. Estudou na Universidade de Alcalá, onde lecionou Retórica, manifestando aí seu interesse pelos estudos históricos. Foi nomeado, em 1563, cronista-mor dando continuidade à obra Coronica general de Espana, publicando em 1574 o seu primeiro volume. Na obra ‘Coronica General de Espana’, Ocampo se propunha a narrar com certa unidade a história da Espanha. Planejada em oitenta volumes, foram publicados apenas cinco: quatro em Zamora, em 1543 e um em Medina, em 1553. Nesta edição os dois primeiros volumes foram reunidos. Palau considera-a uma obra fabulosa sobre as origens dos espanhóis e da Espanha. Segundo Brunet, esta obra teve algumas reimpressões com notáveis adições em Medina dei Campo, em 1553, em Alcalá, em 1578, e em Madri no período de 1791 e 1792, em dez volumes.

Discontinuous growth mechanisms of mode II crack under high-speed impact conditions

A recoverable plate impact testing technology has been used for studying the growth mechanisms of mode II crack. The results show that interactions of microcracks ahead of a crack tip cause the crack growth unsteadily. Failure mode transitions of materials were observed. Based on the observations, a discontinuous crack growth model was established. Analysis shows that the shear crack grows unsteady as the growth speed is between the Rayleigh wave speed c(R) and the shear wave speed c(s); however, when the growth speed approaches root 2c(s), the crack grows steadily. The transient microcrack growth makes the main crack speed to jump from subsonic to intersonic and the steady growth of all the sub-cracks leads the main crack to grow stably at an intersonic speed.
