In August 1983 the Authors studied 36 patients with Plasmodium falciparum malaria and 14 normal individuals born in Humaita region who had never had malaria, had no spleen enlargement and had negative parasitemia as well as passive hemagglutination. Medical histories were obtained and complete physical examination were performed in all of them just as blood tests, parasite density and lymphocyte typing. The lymphocytes were separated and then frozen in liquid nitrogen for later typing by rosette formation. The patients were divided in two groups according to the presence (13 patients) or abscence (23 patients) of gametocytes before treatment. Severe malaria was predominant in the group without gametocytes. The results showed a decrease in the T-cell numbers in Plasmodium falciparum acute malaria patients both with or without gametocytes before the treatment, while B-cell numbers were normal only in the patients with gametocytes. These observations as like as those previously reported by the Authors, permit to associate the presence of gametocytes in peripheral blood and normal number of B-cells in patients with mild Plasmodium falciparum malaria.

La cal es un material producido a partir de la calcinación de la roca caliza y tiene diversas utilidades en el mundo de la industria como la siderúrgica, papelera, alimentaria, en la construcción, entre otras. Es fundamental conocer todas las características de la caliza para poder determinar su grado de calcinación. Con el presente trabajo se pretende estudiar las propiedades de la caliza para su posterior calcinación y el dimensionamiento de una planta de producción de cal desde que el mineral llega de la explotación hasta que sale al mercado. Para determinar los equipos se calcularon sus dimensiones para una producción de 600 t/h de cal, sabiendo que la planta principal de machaqueo solo trabajará 5 días de la semana en jornadas de 8 horas, mientras que a partir del horno de calcinación estará en funcionamiento los 7 días de la semana, 24 horas al día. A partir de esas consideraciones se obtienen las dimensiones de todos los equipos y se realiza un estudio para la elección de un horno, o un horno de eje vertical y un horno rotativo, así como el combustible empleado, ya que es una parte fundamental para determinar los costes para la producción de cal. También fue objeto de este trabajo, el estudio ambiental de la instalación de la planta, en función de la mezcla de combustible empleada y del impacto en el entorno de la misma, así como un estudio de viabilidad de la planta, estimando unos costes de la misma y un precio de mercado “ex‐Works”.

"Las Finanzas, como disciplina académica, nacen a caballo entre los siglos XIX y XX. Sin duda el importante desarrollo industrial de la época y la necesidad de empresas de mayores dimensiones llevaron a un creciente interés por las concentraciones empresariales como fusiones y adquisiciones. También aumentó el interés por los mercados donde se financiaban estas empresas cada vez mayores. Y esto, aunque sucedía en diversas partes del mundo, estaba ocurriendo de forma especial en Estados Unidos, de manera que allí fue donde nacieron las finanzas, y donde se han seguido desarrollando. De esta manera, desde un comienzo, las finanzas tienen un claro sello anglosajón." [introdução]

Texto dividido em duas partes, na primeira aborda-se a evolução do teatro em Portugal do pós segunda grande guerra à contemporaneidade, focando particularmente o experimentalismo do final dos anos quarenta, um período que se pode caracterizar por uma ânsia de renovação e modernização; a constituição de um teatro independente fortemente politizado nos anos setenta; e a pluralidade da cena contemporânea. Na segunda parte aborda-se a alegada incapacidade atávica dos escritores portugueses para a escrita dramática, mapeando os nomes mais significativos do pós-25 de Abril de 1974 até à contemporaneidade.

Este trabajo pretende concretar las expectativas sobre el refuerzo de la independencia de los auditores en la Unión Europa como medio escogido para poder abordar los conflictos de intereses inherentes al panorama actual, caracterizado por factores como el nombramiento de los auditores por la empresa auditada, bajos niveles de rotación o la prestación de servicios distintos a la auditoría. En este momento de crisis, la “International Federation of Accountants” (IFAC) reclama a la profesión auditora que desempeñe un papel activo en el desarrollo de organizaciones, mercados financieros y economías estables y sostenibles; por su parte, la Unión Europea considera conveniente seguir debatiendo la función de las auditorías como garante de la veracidad de la solidez financiera de las empresas. Nuestro objetivo es concretar la incidencia de las propuestas de modificación de la Octava Directiva provocará en la normativa interna de España y Portugal. Se definen cambios importantes, sobre todo en el caso de las Entidades consideradas de Interés Público (EIP), en temas como la rotación obligatoria, el fortalecimiento del Comité de Auditoría o la prohibición de la prestación de servicios adicionales. Se concluye que la Comisión Europea se encuentra en un momento histórico en el que debe plantear si modifica o no las reglas de juego de la prestación de servicios de auditoría que busquen reforzar esa imagen del auditor como un servicio de interés público.

This paper discusses the changes brought by the communication revolution in teaching and learning in the scope of LSP. Its aim is to provide an insight on how teaching which was bi-dimensional, turned into a multidimensional system, gathering other complementary resources that have transformed, in a incredibly short time, the ways we receive share and store information, for instance as professionals, and keep in touch with our peers. The increasing rise of electronic publications, the incredible boom of social and professional networks, search engines, blogs, list servs, forums, e-mail blasts, Facebook pages, YouTube contents, Tweets and Apps, have twisted the way information is conveyed. Classes ceased to be predictable and have been empowered by digital platforms, innumerous and different data repositories (TILDE, IATE, LINGUEE, and so many other terminological data banks) that have definitely transformed the academic world in general and tertiary education in particular. There is a bulk of information to be digested by students, who are no longer passive but instead responsible and active for their academic outcomes. The question is whether they possess the tools to select only what is accurate and important for a certain subject or assignment, due to that overflow? Due to the reduction of the number of course years in most degrees, after the implementation of Bologna and the shrinking of the curricula contents, have students the possibility of developing critical thinking? Both teaching and learning rely on digital resources to improve the speed of the spreading of knowledge. But have those changes been effective to promote really communication? Furthermore, with the increasing Apps that have already been developed and will continue to appear for learning foreign languages, for translation among others, will the students feel the need of learning them once they have those Apps. These are some the questions we would like to discuss in our paper.

The Anchitherium remains from several Portuguese localities placed on IVb and Vb (Lisbon area) levels are studied. They are compared with the French and Spanish remains, and particularly with those from the Madrid basin. They are identified as Anchitherium cf. A. ezquerrae from the Vb level remains, because the remains are very scarce.

Erosion surfaces are the main geomorphological features of the Hesperian Massif. However, three other physiographic elements define the present state of the landscape. Such are big mountain blocks with polygonal borders building at great scale mountain chains, some more modest ridges following hercynian structural trends, and finally the strong incision of the fluvial net. On the other hand, paleoalterations and associated sediments are the only available ways for relief correlation and interpretation. It consists of a triple relationship giving good results when the regional stratigraphy is well known. Tectonic massifs, differential relief sand incisions are originated by geotectonic alpine disturbances during the Tertiary. The three events are consecutive in time with overlapping lapses which the prior and following element: differencial reliefs as a mesozoic heritage occur first, afterwards morphostructural blocks responding directly to the alpine deformation, and finally the fluvial incision as a delayed answer to the preceding morphostructural changes. The relationship relief sedimentation confirms widely this idea, since an association exists between a siderolitic Cretaceous-lower Paleogene and the differential reliefs, between arkoses from the upper Paleogene and the tectonic morphostructural blocks and between the Neogene Series Ocres and the terraces.

Based upon the depositional sequences in the Guadalquivir basin and the bio-events defined (foraminifera and nanoplancton) we present the synthesis of the paleontological results in correlation with the Neogene of Algarve (Portugal). We present the most representative outcrops for micropaleonlologic results, as well as paleoenvironmental correlations between Algarve and the Guadalquivir basin.
