Listado actualizado y comentado de las babosas terrestres (Mollusca: Gastropoda: Stylommatophora) de la península ibérica y las islas Baleares
2022
En este artículo recopilamos y comentamos la lista de las especies de babosas terrestres (“Pulmonados desnudos”) de la península ibérica (algunas también presentes en el sur de Francia) e islas Baleares, basándonos en una revisión bibliográfica hasta el nivel de especie y en nuestras propias recolecciones. Está formada por 71 especies, de las cuales 34 son endémicas, y de ellas sólo dos de Baleares, pertenecientes a 9 familias y 16 géneros. Realizamos 30 comentarios sobre diversas características morfo-anatómicas de algunos taxones del listado y se discuten algunos aspectos nomenclaturales…
La expansión geográfica de la renta del tabaco
2007
El monopolio real del tabaco fue decretado sólo para la Corona de Castilla en 1636. Debido a su reconocida eficacia, los gobernantes españoles intentaron implantarlo allá donde fuese políticamente posible. Después de la guerra de Sucesión, fue establecido en la Corona de Aragón, ya que estos territorios perdieron entonces su régimen foral de autonomía. Como las provincias vascas y Navarra consiguieron conservar su régimen foral, el Gobierno español no pudo someter allí el régimen general del estanco tabaquero y tuvo que contentarse con negociar soluciones que no perjudicasen al estanco general. Finalmente, en el contexto de las reformas borbónicas en América, la Renta del Tabaco fue gradual…
Geographic variation of the Greater white-toothed shrew (Crocidura russula Hermann, 1780 Mammalia, Soricidae)
1996
A multivariate morphometric study of the Greater white-toothed shrew (C. russula) throughout its Palearctic range was carried out to search for patterns of geographic variation within the species boundary. Burnaby's and multiple group principal component analysis allowed the adjustment of raw data with respect to within-sample allometric variation. Multivariate 'size-free' results show a stepped cline with the phenotypical trait reduction and shape change from the eastern to the western Maghreb. Pleistocene fossil mandibles proved to have low phenetic distances with eastern populations (Tunisia, east Algeria) and it is argued that their character set is the primitive condition. The ancestra…
A renewable energy mix to supply small islands. A comparative study applied to Balearic Islands and Fiji
2019
Abstract Power plants supplied by renewables are expanding around the world, increasing the sustainability of the energy sector. In this context, small islands are heavily reliant on fossil fuels. However, this paper shows that the same problem can be found also in small islands belonging to developed countries. To increase the energy sustainability of small islands, the authors assembled a simplified mathematical approach to evaluate the potential electricity production, exploiting the local available energy sources: solar, wind and sea wave. The mathematical model requires few information in input, such as climatic data about the local energy sources and technical features on the selected…

Cephalic anatomy of Sinentomon erythranum Yin (Protura : Sinentomidae)
1992
Abstract The structure of the head capsule, endoskeletal structures, oral folds, mouthparts, foregut, maxillary and labial glands, and the central nervous system of the Chinese proturan Sinentomon erythranum Yin (Protura : Sinentomidae) have been described. The most significant features are the unusual thickness of the cuticle with numerous serrated lines, the reduction of sutures and the absence of linea ventralis, the simplification of gnathal pieces, and the reduction of the musculature. A comparison with other Protura and Apterygota leads to some morphological and phylogenetical interpretations of the cephalic structures, in particular those concerning the entotrophy.
Relevance of air-to-liquid mass ratio effect on final granule properties of an Enalapril maleate formulation.
2011
In the production of enalapril maleate tablets, the granulation process is the most crucial step. Numerous variables are known to influence the fluid bed granulation process and thus the final granule quality. In this study a novel descriptor for the nozzle parameter "air-to-liquid mass ratio" is presented. Granules manufacturing processes were designed by application of statistical experimental design.The influence of the critical process parameter (CPP)--air-to-liquid mass ratio--on pharmaceutic properties of granules was studied. Air-to-liquid mass ratio can be considered as important variable influencing the droplet size of atomized liquid binder solution.A significant influence of air-…
The depletion of nuclear glutathione impairs cell proliferation in 3t3 fibroblasts.
2009
BACKGROUND:Glutathione is considered essential for survival in mammalian cells and yeast but not in prokaryotic cells. The presence of a nuclear pool of glutathione has been demonstrated but its role in cellular proliferation and differentiation is still a matter of debate. PRINCIPAL FINDINGS:We have studied proliferation of 3T3 fibroblasts for a period of 5 days. Cells were treated with two well known depleting agents, diethyl maleate (DEM) and buthionine sulfoximine (BSO), and the cellular and nuclear glutathione levels were assessed by analytical and confocal microscopic techniques, respectively. Both agents decreased total cellular glutathione although depletion by BSO was more sustaine…
Rollio delle navi in presenza di onde modellate come processi gaussiani e poissoniani agenti simultaneamente.
2008
Obiettivo del presente lavoro è l’estensione del metodo della path integral solution (PIS) per lo studio della dinamica del rollio delle navi in presenza di onde modellate come processi gaussiani e poissionani agenti simultaneamente. Si è proceduto dapprima a mostrare come la PIS consenta di valutare l’evoluzione temporale della funzione densità di probabilità (PDF) del processo di risposta, applicando il metodo ad equazioni differenziali stocastiche soggette a forzanti esterne gaussiane e poissoniane. Successivamente si è trattato il caso di un sistema non lineare soggetto ad entrambi i rumori gaussiano e poissoniano agenti contestualmente. Si è infine affrontato sia analiticamente che num…
