COLOR ABERRATIONS IN TWO SPECIES OF NEW WORLD VULTURES (CATHARTIDAE)
Abstract ∙ We present information on two cases of color aberrations in two species of vultures: one individual of Turkey Vulture (Cathartes aura) in Mexico and one of Black Vulture (Coragyps atratus) in Costa Rica. Both cases were determined to be ino, wherein birds have very pale brown eumelanin. We discuss these two cases and compare them with other cases of abnormally colored vultures from several island and mainland areas in America. Resumen ∙ Aberración de color en dos especies de buitres del Nuevo mundo Presentamos información sobre dos casos de anormalidad pigmentaria en dos especies de buitres: un individuo de Zopilote Aura (Cathartes aura) en México y otro de Zopilote Negro (Coragyps atratus) en Costa Rica. Ambos casos fueron determinados como ino, donde las aves tienen eumelanina café muy pálida. Discutimos estos dos casos y los comparamos con otros casos de buitres de coloración anormal de varias áreas continentales e islas en América

La Biodiversidad y su transposición didáctica en el currículo de Primaria en las Leyes Orgánicas de Educación desde la LOGSE (1990)
There are few studies on the treatment of biodiversity in the Primary Education curriculum. There are even less on the didactic transposition of the Scientific Knowledge behind this concept to the Laws on Education. This study tries to delve into the quality of that step by offering both with a qualitative and quantitative analysis on biodiversity’s transposition; referred to both the national level and Andalusia one. Major mistakes and shortcomings of the transposition are analyzed, and possible updates are pointed out while comparing national and regional scopes. Also, we assess the chronological evolution of the process through various laws up the current LOMCE; we found biodiversity’s transposition is incomplete, unbalanced and unstructured, with differences between the national and regional level; finally, no significant learning on biodiversity seems to be guaranteed.
Keywords: biodiversity; didactic transposition; elementary curriculum; educational law.Existen muy pocos estudios sobre el tratamiento de la biodiversidad en el currículo de Primaria, así como sobre la transposición didáctica desde el Saber Sabio de este concepto a las Leyes Orgánicas de Educación. Este estudio intenta profundizar en la calidad de ese primer paso transpositivo en el currículo de Primaria, a través de un análisis cualitativo y cuantitativo de dicho proceso mediante una metodología que cuantifica y evalúa el tratamiento de la biodiversidad a nivel nacional y autonómico andaluz. Se comprueba que la transposición de la biodiversidad es incompleta, desigual y desestructurada. Se analizan los principales errores y carencias del proceso, y se señalan posibles actualizaciones, comparando ambos niveles a través de las distintas Leyes hasta la actual LOMCE. La conclusión final apunta a que no se facilita un aprendizaje de calidad con el actual marco curricular.

The Atticus code. Tribute to Professor Javier de Lucas Martín
Javier de Lucas has successfully and rigorously tackled many research topics in his long academic life. From immigration, racism and xenophobia, to civil disobedience and conscientious objection, through his doctoral thesis on Durkheim or his work on classics such as Condorcet, the concept of solidarity, tolerance, the principle of sovereignty, the paternalistic justification of power, secrecy and transparency or the Kantian principle of publicity, among many others. This brief article, however, focuses on a very specific content of his enormous work: the Atticus code and its relationship with the ideal of the rule of law and democracy
Controlador de tele asistencia para procesos domoticos
Graficas, diagramas, tablasEn este Proyecto se desarrollará unos parámetros relacionados con el control y la seguridad; a través de medios de telecomunicación, para brindar una solución al manejo de dispositivos eléctricos y electrónicos. Con el fin de lograr una interacción, en los sistemas relacionados con la domótica.
Se desea con el proyecto, dar un paso hacia nuevas técnicas y herramientas, que generen un fácil acceso de dispositivos eléctricos y electrónicos en una residencia; con el uso de controles que estén al alcance de usuarios en condiciones normales o de discapacidad.
Con este proyecto se pretenden generar beneficios en el medio ambiente, como el uso y aprovechamiento de los recursos naturales como son, el sol para poder transformar esta energía en energía eléctrica. Este proyecto utilizara al máximo los recursos, aprovechando el proceso de reciclaje.This Project will develop parameters related to control and safety; through

Hearing regeneration and regenerative medicine: present and future approaches
More than 5% of the world population lives with a hearing impairment. The
main factors responsible for hearing degeneration are ototoxic drugs, aging,
continued exposure to excessive noise and infections. The pool of adult stem
cells in the inner ear drops dramatically after birth, and therefore an endogenous
cellular source for regeneration is absent. Hearing loss can emerge
after the degeneration of different cochlear components, so there are multiple
targets to be reached, such as hair cells (HCs), spiral ganglion neurons
(SGNs), supporting cells (SCs) and ribbon synapses. Important discoveries in
the hearing regeneration field have been reported regarding stem cell transplantation,
migration and survival; genetic systems for cell fate monitoring;
and stem cell differentiation to HCs, SGNs and SCs using adult stem cells,
embryonic stem cells and induced pluripotent stem cells. Moreover, some
molecular mediators that affect the establishment of functional synapses
have been identified. In this review, we will focus on reporting the state of
the art in the regenerative medicine field for hearing recovery. Stem cell
research has enabled remarkable advances in regeneration, particularly in
neuronal cells and synapses. Despite the progress achieved, there are certain
issues that need a deeper development to improve the results already
obtained, or to develop new approaches aiming for the clinical application.Ministry of Economy and Competitiveness (Project

The Construction of Stations and Tunnels by Slurry Trecnch, Method in the Madrid Metro Extension
Recently a new Extension of the Madrid Subway (Spain) is carried out (1995-2003). In 8 years more of 105 Km of tunnels are builded by several procedures: Traditional non-mechanized excavation, precast linings by E.P.B machines, cut and cover system, etc. In this paper the basic criteria adopted for the design of tunnels and stations built with the cut and cover method (reinforced concrete continuous and discontinuous walls) are analysed. Initially, to this purpose the geotechnical properties of the Madrid ground are reached, in order to establish a group of unified desion geotechnical parameters. The hypotheses made for the numerical analysis of in situ walls are shown (calculation model, water pressures, etc), together with the installed instrumentation and the obtained results
