Ectoparasites on bats (Gamasida, Ixodida, Diptera) in Biscay (N lberian peninsula)

A study on ectoparasites infesting Chiroptera in Biscay (N lberian peninsula) was carried out during a distribution survey of bats. 160 potential hosts were examined and 664 ectoparasites were found, collected manually from living bats by means of pointed tweezers. The ectoparasites belonged to 12 species and 2 subspecies: 5 species and 2 subspecies of Gamasida, 2 species of lxodida and 5 species of Diptera. First records in the study area were obtained for Eyndhovenia euryalis euryalis, Eyndhovenia euryalis oudemansi, Argas vespertilionis and Penicillidia dufouri. Spinturnix plecotina on Rhinolophus ferrumequinum and Rhinolophus euryale and lxodes vespertilionis on Myotis nattereri are reported for the first time in the lberian peninsula; Basilia nattereri is new on Myotis nattereriin Biscay. Associations between parasites and hosts are also reported.

Infrared sensor-based temperature control for domestic induction cooktops

In this paper, a precise real-time temperature control system based on infrared (IR) thermometry for domestic induction cooking is presented. The temperature in the vessel constitutes the control variable of the closed-loop power control system implemented in a commercial induction cooker. A proportional-integral controller is applied to establish the output power level in order to reach the target temperature. An optical system and a signal conditioning circuit have been implemented. For the signal processing a microprocessor with 12-bit ADC and a sampling rate of 1 Ksps has been used. The analysis of the contributions to the infrared radiation permits the definition of a procedure to estimate the temperature of the vessel with a maximum temperature error of 5 °C in the range between 60 and 250 °C for a known cookware emissivity. A simple and necessary calibration procedure with a black-body sample is presented

Microwave-Assisted Synthesis of Some 1H-1,2,4-Triazol-3-one Derivatives

4-Amino-5-(methyl/ethyl)-2,4-dihydro-3H-1,2,4-triazol-3-one were synthesized from the reaction of (methyl/ethyl)-ester ethoxycarbonyl hydrazone with hydrazine hydrate and then, converted to corresponding Schiff bases using 9H-fluorene- 3-carbaldehyde. Ester, hydrazide and oxadiazole derivatives were synthesized starting from Schiff bases in three steps. All reactions occurred under conventional conditions and microwave irradiation. The obtained results were compared.KEYWORDS Triazole, oxadiazole, hydrazine hydrate, microwave irradiation

Resonant spin tunneling in randomly oriented nanospheres of Mn 12 acetate

Under the terms of the Creative Commons Attribution license (3.0 Unported or 4.0 International).-- et al.We report measurements and theoretical analysis of resonant spin tunneling in randomly oriented nanospheres of a molecular magnet. Amorphous nanospheres of Mn 12 acetate have been fabricated and characterized by chemical, infrared, TEM, x-ray, and magnetic methods. Magnetic measurements have revealed sharp tunneling peaks in the field derivative of the magnetization that occur at the typical resonant field values for the Mn 12 acetate crystal in the field parallel to the easy axis. Theoretical analysis is provided that explains these observations. We argue that resonant spin tunneling in a molecular magnet can be established in a powder sample, without the need for a single crystal and without aligning the easy magnetization axes of the molecules. This is confirmed by reanalyzing the old data on a powdered sample of nonoriented micron-size crystals of Mn 12 acetate. Our findings can greatly simplify the selection of candidates for quantum spin tunneling among newly synthesized molecular magnets.The work at the University of Barcelona has been supported by Spanish Government Project No. MAT2011-23698.

Characters of the Stephanian-Permian Bronchales basin and the tourmalinization associated to calc-alkaline rhyolites (Teruel Province)

[Resumen] La turmalinización que afecta a riolitas calco-alcalinas presentes en la fosa transtensional de Bronchales, con edad Autuniense, destaca por el elevado contenido en B (0.87 O/o de promedio). Esta mineralización muestra un enriqueciIl\iento de HREE y un empobrecimiento en LREE debido a que el fluido mineralizante (rico en F) pudo ejercer una función acomplejante para estos elementos y, también, con carácter selectivo, para As, Sn, Sb y Bi.[Abstract] Calc-alkaline rhyolites of Bronchales transtensional basin (Autunian age) are affected by a tourmalinization process. Tourmalinized rhyolites with 0.87 O/o ofboron as average value show As, Sb, Sn and Bi increments over nontourmalinized ones, as well as important enrichments of HREE over LREE possibly because tourmalinization fluids were enriched in complexing agents (i.e .F)

Setting, Petrology and Geochemistry of the Volcanoclastic Complex of Orea (Guadalajara, Iberian Chain)

[Abstract] The volcanoclastic outcrop ofOrea (south margin of the Iberian Chain) reflects a pluriepisodic igneous activity, expressed in agglomerates and tuffs ofdacitic composition (with a calc-alkaline affinity) and Autunian-Thuringian age. The tuffs are the results' of a hydromagmatic activity, developed under a thin sheet of water (in a paludal environment). The structure of the magmatic outcrop results of the late-Hercynian extensional tectonics, equivalent to that observed in many other outcrops ofthe southeast border ofthe Iberian Chain. The setting characters and composition of the involved magmatic rock-types, suggest the presence of only one volcanic focus, as in other coetaneous half-grabens of this sector of the Iberian Chain

Triassic tholeiitic dolerites («ophites») of the El Grado diapir (Pyrenees, Huesca, Spain): emplacement and composition

Mesozoic dolerites in the south Pyrenean sector of El Grado (Huesca, Spain) preserve emplacement structures (fluidity structures at the top and load structures at the base) developed during their intrusion into unconsolidated marly-evaporitic Triassic sediments (Keuper facies). By analogy with other dolerites in the south Pyrenean domain, their emplacement age is equivalent to the uppermost Keuper facies terms, but prior to the final Triassic-early Liassic carbonated sediments. Radiometric ages (187-197±7 Ma) show that the emplacement occurred during the lower Liassic. The petralogical differentiation from the chilled margin facies to the central facies, and also to the late pegmatitoids, is consistent with that obtained from major elements, trace elements and REE. Their tholeiitic affinity, as defined by their geochemical composition, is equivalent to that of similar racks in the Pyrenean domain. However, the rocks analyzed here, which are located at the external sector of this domain, display a greater petralogical and geochemical differentiation as compared to similar rocks in the central sectors of the Pyrenean domain.Las doleritas mesozoicas del sector surpirenaico de El Grado (Huesca) conservan estructuras de emplazamiento (con desarrollo del movimiento de lava fluida al techo y de carga en su base) desarrolladas al instruir en los sedimentos margo-evaporíticos en facies Keuper, todavía inconsolidados. Por similitud con otras doleritas del dominio surpirenaico, la edad del emplazamiento es equivalente a la de los términos superiores de la facies Keuper y previa a la sedimentación carbonatada del Trías terminal-Lías inferior. Las determinaciones de edades radiométricas (187-197±7 Ma) indican que el emplazamiento debió tener lugar durante el Lías inferior. La diferenciación petralógica, desde la facies del borde enfriado a la central y, también, al posterior diferenciado pegmatoide concuerda con la obtenida con elementos mayores, trazas y REE. Su afinidad toleítica, definida por su composición geoquímica, coincide con la obtenida en rocas análogas para el dominio pirenaico; no obstante, estas rocas situadas en el borde más externo de dicho dominio representan una mayor diferenciación (petralógica y geoquímica) respecto a la obtenida, hasta el momento, para rocas análogas situadas en sectores más centrales del citado dominio pirenaico

The triassic alkaline dolerites of the Valacloche-Camarena Area (SE-Iberian Chain, Teruel): Geodynamic implications

The dolerite sills outcropping in the Valacloche-Camarena area (SE Iberian Chain), are the expression of an alkaline magmatism, emplaced in Keuper facies sedimentary rocks. Their pre-Hettangian age is deduced from the development of fluidality structures at the top of the sills together with the very low grade contact metamorphism of the host rocks. A differentiation trend, represented by two rock-types, with variable Ti-augite content, is confirmed by geochemical data (REE). The alkaline composition of this magmatism is close to that of the OIB type. Crust-derived enclaves (metapelites and granitoids) are common in these sills, suggesting that magma ascent took place through a fracture system, related to a distensive tectonic regime, that affected different levels of the crust. This magmatism was one of the expressions of the triassic rifting events that are well represented in the SE border of the Iberian Chain.Un magmatismo alcalino, emplazado en sedimentos triásicos en facies Keuper, está bien representado en los sills doleríticos del área de Valacloche-Camarena (SE de la Cordillera Ibérica). La edad pre-Hettangiense ha sido deducida a partir de la presencia de estructuras de fluidalidad y de un metamorfismo de contacto de grado muy débil. Petrológicamente se identifica una fraccionación según dos litotipos (con contenido variable en Ti-augita) que está corroborada por los datos de composición geoquímica (en tierras raras); la composición alcalina de este magmatismo es próxima a la del tipo OIB. La presencia, frecuente, de enclaves de corteza (metapelitas y granitoides) indica una fracturación que, en condiciones distensivas, afectó a distintos niveles de dicha corteza. Este magmatismo está ligado al rifting triásico que está bien expresado en el borde SE de la Cordillera Ibérica
