The geometric mean regression equation for the weight; length relationship of Cynoglossus canariensis was W = 0.0025 L super(3.1770). The Von Bertalanffy constants Woo, Loo, K, and to were 507.5852 g, 47.3683 cm, 0.3333 and 0.1397 for males and 839.0753 g, 54.4720 cm, 0.3062 and 0.1737 for females. Total mortality coefficient Z ranged from 0.6482 and 0.8021

Cynoglossus canariensis has a very rapid growth. The rate of the males is 0,36 and the female one is 0,32. The asymptotic size is 55,0cm for the females and 50,5cm for the males. Females and males younger than three years (40cm), which represent 90 per cent of the Côte d'Ivoire stock have a similar growth, so the average equation: Lt=53,5 (1-e -0,34(t+1)) will be used.

Charles Henry Gilbert (Fig. 1) was a pioneer ichthyologist and, later, fishery biologist of particular significance to natural history of the western United States. Born in Rockford, Illinois on 5 December 1859, he spent his early years in Indianapolis, Indiana, where, in 1874, he came under the influence of his high school teacher, David Starr Jordan (1851-1931). Gilbert graduated from high school in 1875, and when Jordan became a professor of natural history at Butler University in Irvington, Indiana, Gilbert followed, and received his B.A. degree in 1879. Jordan moved to Indiana University, in Bloomington, in the fall of 1879, and Gilbert again followed, earning his M.S. degree in 1882 and his Ph.D. in 1883 in zoology. His doctorate was the first ever awarded by Indiana University.

Tylopharynx clariamphida sp. n. is described from muddy sand collected in Anhui Province, China. It can be distinguished from T foetida (Butschli, 1874), the type and only species of the genus, by numerous characters: having 24 to 26 prominent and clearly separated longitudinal ridges, a higher lip region with no hint of a cephalic framework, more prominent amphidial foveae in lateral view, wider and more posteriorly located amphidial apertures, smaller basal knobs of stoma, longer metacorpus, more enlarged phasmids, shorter spicules with shorter digitate terminus, shorter reflexed part of testis, and thicker gubernaculum with more angular shape. For comparison, an expanded description is given for T foetida from Belgium, and SEM photographs of both species are provided.

For my dissertation, I did a study and performance of American violin works by Charles Ives, Aaron Copland, Leonard Bernstein, and John Corigliano, along with contemporaneous European works by Paul Hindemith, Bela Bartok, Igor Stravinsky, Sergei Prokofiev, and Francis Poulenc. The selected American violin works display the development of a distinctively American style and cover a significant formative period (1914-1963) of American classical music. I intend that the European works form a backdrop for setting in relief any distinctly American qualities possessed by the American works. This is because they cover a similar time period and have significant stylistic affinities and shared influences. My topic stems from a question, "What defines the American Sound?" I attempted to find the answer by looking at the time when American composers consciously searched for their identities, and declared their music to be distinctly American. I found that those distinctive qualities stemmed from three sources: folk music, jazz and hymns. Ives and Copland can be viewed as American in content for their inclusion of such elements, while Bernstein and Corigliano can also be considered as "ideologically American" for their adventurous and eclectic spirit. The simplicity derived from singing a hymn or crooning a popular song; the freedom inspired by jazz; the optimism of accepting all possibilities-these elements inform the common spirit that I found in the music of these four American composers.

The ascidian Corella eumyota, originally from the Southern Hemisphere, was first reported in the Northern Hemisphere in Brittany, France, in 2002. Since then, it has been recorded in Spain, Ireland, the south coast of England and South Wales. Most European records to date have been from artificial habitats such as marinas. In Plymouth, England, C. eumyota was first found in two marinas in 2005 but individuals were soon also detected in small numbers on nearby shores. Shore surveys in March and August of 2008 indicated that C. eumyota has established reproductive populations on natural and semi-natural shores of Plymouth Sound and the adjacent coastline, largely restricted to relatively sheltered sites in the lower reaches of estuaries. At these sites it is generally the most abundant non-colonial ascidian. The species clearly has the capacity to become a significant component of the biota of sheltered shores in the Northern Hemisphere.

This article has developed with the intention of analyzing how the stereotypes, prejudices and lies can influence the education of the children. Formation, that usually comes from family and teachers, who sometimes move for extremist ideologies. There exist multiple fictions in which we observe these social archetypes, but it is the case of the movie Pa negre (Agustí Villaronga, 2010), where the principal personage evolves psychologically, because of that its eyes observe and the ideas that the people transmit him on its family, in the rural environments, where the tradition of the rumors coexists.

The journalistic boom that occurred in Argentina from the second half of the nineteenth century saw the emergence of an active afroporteña press that defend the interests of the black community. This paper, in addition to reviewing the history of the Afro-Argentines newspapers, emphasizes the role played by the elite of African descent in the promotion of modernity among his brothers, while exploring the possible bases for an identity in the ideas spread.

In his presidential address to the Belfast meeting of the British Association for the Advancement of Science in 1874, John Tyndall launched what David Livingstone has called a ‘frontal assault on teleology and Christian theism’. Using Tyndall's intervention as a starting point, this paper seeks to understand the attitudes of Presbyterians in the north of Ireland to science in the first three-quarters of the nineteenth century. The first section outlines some background, including the attitude of Presbyterians to science in the eighteenth century, the development of educational facilities in Ireland for the training of Presbyterian ministers, and the specific cultural and political circumstances in Ireland that influenced Presbyterian responses to science more generally. The next two sections examine two specific applications by Irish Presbyterians of the term ‘science’: first, the emergence of a distinctive Presbyterian theology of nature and the application of inductive scientific methodology to the study of theology, and second, the Presbyterian conviction that mind had ascendancy over matter which underpinned their commitment to the development of a science of the mind. The final two sections examine, in turn, the relationship between science and an eschatological reading of the signs of the times, and attitudes to Darwinian evolution in the fifteen years between the publication of The Origin of Species in 1859 and Tyndall's speech in 1874.
