Proyectar/Investigar: Método de Educación Dialógica, Aplicado al Desarrollo de Competencias, en la Iniciación al Dise?o Sostenible
Muoz,M. J;
Formación universitaria , 2009, DOI: 10.4067/S0718-50062009000200004
Abstract: a new method of dialogical education named project/research is study and analyzed. in an experimental step, the method was developed as a research educational project. the application of the method gave origin to a dialogical didactic that was accredited in the architecture school of the polytechnic university of madrid during the three academic courses (2004 -2007). the words project and research describe two activities that normally are understood separate form: design (of the architects) and research (of the scientists). when both words are joined, a communicative system to exchange information is created, a system that it is fundamental to build a new culture. the active principle (project/research system) connects architectonic design and research with others disciplines as art, science, politics or ecology, and allows improving the quality of projects and inserting them in the new sustainability culture.
Mucosal Schwann Cell Hamartoma—Colonic Lesion Susceptible to an Interesting Differential Diagnosis  [PDF]
J. Ortiz, L. Chinchilla, E. Muoz, Md Lude?a
Open Journal of Pathology (OJPathology) , 2018, DOI: 10.4236/ojpathology.2018.83012
Abstract: We present a mucosal Schwann cell hamartoma that was observed in a 63-year-old woman with no personal or family history of interest who underwent a screening colonoscopy for early detection of colon cancer. During colonoscopy, a small polyp with a maximum diameter of 0.8 cm was detected at the rectosigmoid level. Histologically, a benign lesion of neuroid aspect was observed, consisting of multiple spindle cell fascicles that was positive for S-100 and negative for enolase, synaptophysin, CD34, CD117, actin, desmin, Dog1, EMA, and neurofilaments. These findings, supported by the family and personal history of the patient, allowed us to make a diagnosis, discarding other entities.
Nuevos retos y oportunidades para la financiación de los servicios de uso público en los espacios naturales protegidos
M. Muoz,J. Benayas
Ecosistemas , 2007,
Abstract: Nuevos retos y oportunidades para la financiación de los servicios de uso público en los espacios naturales protegidos. La utilización de los espacios naturales protegidos con fines recreativos tiene una larga tradición, sin embargo, los niveles de demanda actuales ha llevado a una situación sin precedentes históricos, que está suponiendo nuevos retos para la gestión de los mismos. Gestionar un número creciente de visitantes minimizando sus impactos en el medio y maximizando su satisfacción y su implicación con la conservación requiere financiación y, hasta el momento, el gran peso de la misma ha recaído sobre los presupuestos públicos. Hasta cuando podrá soportarse esta situación sin que la calidad de los servicios se vea afectada? El uso público en los espacios protegidos de Espa a deberá seguir siendo pagado por presupuestos públicos o deben de ser los usuarios de estos espacios, directamente beneficiados, los que paguen total o parcialmente por los costes correspondientes? La futura financiación del uso público merece una reflexión que impida caer en la improvisación. En este artículo se aporta información que puede ayudar a iniciar un necesario debate.

Relativistic forces in Lagangian mechanics
J. Muoz Díaz
Physics , 2012,
Abstract: We give a general definition of \emph{relativistic force} in the context of Lagrangian mechanics. Once this is done we prove that the only relativistic forces which are linear on the velocities are those coming from differential 2-forms defined on the configuration space. In this sense, electromagnetic fields provide a mechanical system with the simplest type of relativistic forces.
The structure of time and inertial forces in Lagrangian mechanics
J. Muoz Díaz
Mathematics , 2008,
Abstract: Classically time is kept fixed for infinitesimal variations in problems in mechanics. Apparently, there appears to be no mathematical justification in the literature for this standard procedure. This can be explained canonically by unveiling the intrinsic mathematical structure of time in Lagrangian mechanics. Moreover, this structure also offers a general method to deal with inertial forces.
Mobile Calibration Based on Laser Metrology and Approximation Networks
J. Apolinar Muoz-Rodriguez
Sensors , 2010, DOI: 10.3390/s100807681
Abstract: A mobile calibration technique for three-dimensional vision is presented. In this method, vision parameters are computed automatically by approximation networks built based on the position of a camera and image processing of a laser line. The networks also perform three-dimensional visualization. In the proposed system, the setup geometry can be modified online, whereby an online re-calibration is performed based on data provided by the network and the required modifications of extrinsic and intrinsic parameters are thus determined, overcoming any calibration limitations caused by the modification procedure. The mobile calibration also avoids procedures involving references, which are used in traditional online re-calibration methods. The proposed mobile calibration thus improves the accuracy and performance of the three-dimensional vision because online data of calibrated references are not passed on to the vision system. This work represents a contribution to the field of online re-calibration, as verified by a comparison with the results based on lighting methods, which are calibrated and re-calibrated via perspective projection. Processing time is also studied.
ANáLISIS MECáNICO Y TRIBOLóGICO DE Los RECUBRIMIENTOS Fe-Cr-Ni-C Y Ni-Al-Mo
MUOZ,JORGE E.; CORONADO,JOHN J.;
DYNA , 2007,
Abstract: in this paper the coatings ni=89%, al = 5,5%, mo=5,5% and fe=81,8%, cr=16%, ni=2%, c=0,2% were evaluated. the coatings were applied by flame-thermal spray technique. the superficial preparation method was sand blasting. adhesion, shear, abrasive wear, sliding wear and bending tests were made. the coating fe-cr-ni-c presented minor mass loss, as much for abrasive wear as for the sliding wear. the multilayer presented a greater porosity in the base layer (ni-al-mo) than in the outer layer (fe-cr-ni-c), the last one presented greater amount of nonfused particles and oxides. the failure presented in the adhesion test for the samples with multilayer coating was of adhesive and cohesive characteristic. the stress in which the cracks appear by bending moment in the multilayer coatings diminished with the increase of the thickness.
ESTUDIO SOBRE LAS FUNCIONES PRAGMADISCURSIVAS DE ?NO? Y ?EH? EN EL ESPA?OL HABLADO
Rodríguez Muoz,Francisco J.;
RLA. Revista de lingüística teórica y aplicada , 2009, DOI: 10.4067/S0718-48832009000100005
Abstract: this study compares the pragmatic functions of ?no? and ?eh? discursive particles which show some similarities in spoken spanish, such as the deictic feature of appeal to the interlocutor that both include. the analysis uses a heterogeneous corpus of two spontaneous conversations, three interviews and other examples of discourse genres from crea. linguistic data reveal certain differences in the semantic, communicative and intonational uses of these discourse markers.
Useful ratios between two-body nonleptonic and semileptonic decays of B mesons
Muoz, J.H.;Quintero, N.;
Revista mexicana de física E , 2011,
Abstract: we compute important ratios between decay widths of some exclusive two-body nonleptonic and semileptonic b decays, which could be test of factorization hypothesis. we also present a summary of the expressions of the decay widths and differential decay rates of these decays, at tree level, including l = 0 (ground state), l = 1 (orbitally excited) and n = 2 (radially excited) mesons in the final state. from a general point of view, we consider eight transitions, namely h p,v, s, a, a' , t, p (2s), v (2s). our analysis is carried out assuming factorization hypothesis and using the wsb, isgw and clfa quark models.
