Hexarthra bulgarica was found in 16 of the 37 high mountain lakes (over 2500 m) studied in the Sierra Nevada (Southern Spain). These populations resemble closely the subspecies H. b. canadensis. Data on the morphology and ecology of the Sierra Nevada populations are given, and these are compared to published information on the three other subspecies of H. bulgarica.

The ionic composition of 38 mineral springs in the province of Granada (Spain), and the distribution of 45 species of nematodes belonging to orders Monhysterida, Araeolaimida, Chromadorida and Enoplida were examined. Water chemistry is used to make two diagrams representing anionic and cationic composition. Diagrams for anionic composition (given the greater variance seen in the springs considered) are used to illustrate the distribution of individual species. The results obtained from species distribution and the correlation between species made it possible to group species which could be associated with springs where each of the anions considered predominated. A greater number of species groups was found to inhabit springs in which chloride concentrations was less than 50% of the total concentration of anions.

A methodology for port management is proposed in this work. It takes into account the uncertainty of the port performance due to the action of random forcing agents, namely, climate agents and exploitation agents. It can be used to obtain optimal solutions for port management problems in which operationality and safety are involved. Multivariate simulation techniques are used to obtain realizations of the random processes that characterize the forcing agents. The port performance is then evaluated by a simulation model. The methodology is applied in a hypothetical port in which the influence of the climate thresholds on operational performance and safety is evaluated by the port simulation model. An optimization problem is then formulated and solved in order to reduce waiting times and costs without compromise the safety levels.

In March 2011 Consejo de Estado has said, answering to a goverment’s question, that it is posible to enact a law in Spain that prohibits or limits the advertisements about prostitution in the press. The author centre his comments to the most relevant questions that, from a constitutional perspective, he arisenes the problem and agrees with the arguments adopted by Consejo de Estado.El Consejo de Estado llega a la conclusión de que es acorde con el Derecho español la adopción de medidas que coadyuven a la limitación de la publicidad sobre prostitución. Para ello recomienda la elaboración de una nueva ley, que no precisa ser ley orgánica, que incorpore un concepto específico de publicidad a los efectos de la propia disposición legal. El encargo se había planteado al Consejo de Estado por Orden de la entonces Ministra de Igualdad de 12 de mayo 2010, sobre las posibilidades de actuación contra anuncios de contenido sexual y prostitución publicados a diario en la prensa escrita. El autor centra sus comentarios en las cuestiones más relevantes que, desde una perspectiva constitucional, plantea el problema, manifestándose en líneas generales coincidente con las tesis del Consejo de Estado.
