Puntualizaciones documentales y nuevas noticias sobre la reja de la parroquia de Santiago (Cáceres)

Probamos en este artículo la manufactura de la reja de la parroquia de Santiago (Cáceres) por el destacado maestro rejero avecindado en Valladolid Francisco Martínez. Cuya reja, debido al fallecimiento de Martínez en junio de 1564, fue asentada por su yerno, el también rejero Antonio de Molina. Son inéditos los documentos que hacen referencia al transporte de la reja desde Valladolid en diciembre de 1563, manuscritos que ratifican la autoría por parte del citado Martínez antes de su óbito. Y también son inéditas las escrituras referentes al dorado y policromía de dicha reja, trabajo encomendado a los pintores extremeños Diego Muriel Solano y Alonso Rubiales, quienes habían terminado su labor en diciembre de 1564.This article proves that the grille at Santiago’s Parish Church (Cáceres) was manufactured by Master Francisco Martínez, from Valladolid. Due to Matínez’s death in June 1564, the grille was placed on its present location by his son-in-law, Antonio de Molina. The documents that refer to the transportation of the grille from Valladolid in December 1563 have been unpublished up to now. These manuscript documents prove Martinez’s authorship of the grille. The documents referring to the gilding and polychromy of the grille are also unpublished. These documents show that this work was assigned to the Extremaduran painters Diego Muriel Solano and Alonso Rubiales, who had finished their work in December 1564.peerReviewe

An approach to the design of a scale for measuring happiness at work of Iberian companies

By reviewing bibliography on happiness at work, we may say that from a management perspective, this subject is yet poorly explained. So, main reason to conduct this research was he few number of references on organizational happiness in the field of Business and Economics, despite it increasing importance. More specifically, the non-existence of scales to measure happiness at work in Iberia. In this article we aim to propose an exploratory scale to measure happiness at work in Portuguese and Spanish organizations. To do that, we look for primary data collection by using a questionnaire with open questions. The research is qualitative and was conducted applying complementary phases: (1) data collection, (2) storage, (3) coding, (4) indexing system refinement, (5) relational code and (6) identify categories (key concepts). In phases 3, 4, 5, and 6 a content analysis was applied. To analyze the scale robustness in two cultures we have applied Hofstede's model. This model confirms that cultural and social values of Portuguese and Spanish individuals are very similar, allowing homogenizing the scale without significant bias. The scale proposed is based on: (1) total happiness at work, (2) happiness in the organization, and (3) happiness in the function. At the end, happiness at work was measured by 20 items. We consider this research as a significant first step to develop a consistent tool to measure happiness at work

Predictability of the resonance frequency analysis in the survival of dental implants placed in the anterior non-atrophied edentulous mandible

Background: Dental primary implant stability is considered essential in the success of the osseointegration process. The recent advent of the resonance frequency analysis (RFA) seems to effectively measure primary implant stability, although its relationship with implant survival has to be further established. Patients and Methods: Seventy patients with complete mandibular edentulism underwent dental implant rehabilitation by means of the placement of 68 dental implants within the interforaminal region and subsequent placement of an overdenture. Primary implant stability was measured by means of RFA and it was expressed in terms of implant stability quotient (ISQ) on the day of the implant insertion and at the time of the healing abutment placement in a conventional implant two-stage surgical procedure. Results: Overall implant survival rate was 97.1% at the end of the follow-up period. The mean ISQ value for 3.75 and 4.25 mm diameter implants was 78.4 ± 5.46 and 80.83 ± 5.35 respectively, at the time of the implant placement; and 76.68 ± 4.34 and 78.22 ± 6.87 respectively, at the second surgical stage. No statistical differences were observed in relation to changes in mean ISQ value along the healing process Conclusions: No statistical differences in terms of primary and secondary implant stability measured by RFA exists between 3.75 mm and 4.25 mm diameter implants in the conventional implant two-stage surgical procedure in patients with non-atrophied edentulous mandible being restored with an overdenture. Furthermore, no statistical association between RFA and the implant insertion torque was observed for endosseous dental implant placement at the first surgical stage. © Medicina Oral

Temporomandibular joint arthrocentesis. Review of the literature

The treatment of the temporomandibular joint (TMJ) is still controversial. TMJ arthrocentesis represents a form of minimally invasive surgical treatment in patients suffering from internal derangement of the TMJ, especially closed lock. It consists of washing the joint with the possibility of depositing a drug or other therapeutic substance. Resolution of symptoms is due to the removal of chemical inflammatory mediators and changes in intra-articular pressure. Numerous clinical studies regarding this technique have been published. The goal of this paper is to review all clinical articles that have been published with regard to the critique of this technique. 19 articles with different designs fulfilling selection guidelines were chosen. A series of clinical and procedure variables were analyzed. Although the mean of improvement was higher that 80%, further research is needed to determine more homogeneous indications for TMJ athrocentesis

Estudio de la porosidad y la mineralización en el callo de distracción ósea

La distracción ósea es un proceso quirúrgico por el cual se genera hueso nuevo mediante la separación gradual de dos fragmentos óseos y una aplicación gradual de tracción. En este proyecto se busca determinar la evolución de la porosidad y la mineralización durante el proceso de curación a través del procesamiento de imágenes. Existen dos casos distintos de estudio: la evolución de la porosidad y la evolución de la mineralización. Dentro del caso de la evolución de la porosidad se han analizado tres subcasos: el primero incluirá el tejido blando como poro, el segundo no incluirá el hueco del tejido blando como poro y el tercero corresponderá al docking site. Para determinar la validez de los resultados, se han comparado con resultados existentes de estudios previos. Se llega a la conclusión de que la porosidad disminuye durante el proceso de curación, así como una correlación negativa existente con la rigidez del callo de distracción. El contenido mineral del hueso inmaduro tiene una evolución inversamente proporcional a la de la porosidad pero no es función de la porosidad.Distraction osteogenesis is a surgical process by which new bone is generated through the gradual separation of two bone fragments and a gradual traction application. Porosity and mineral content evolution during the healing process are searched in this project by image processing. There are two different cases: porosity evolution and mineral content evolution. Within porosity evolution, three subcases had been studied: in the first one, it is included soft tissue as a pore, in the second one, soft tissue is not included as a pore and the third one is the docking site study. To establish the validity of the results, datas of previous studies were compared with this project results. To conclude, the porosity of the woven bone diminishes during the healing process and that it is negatively correlated to its stiffness. In addition, the mineral content of the woven bone is inversely proportional to the porosity, but it is not a function of the porosity.Universidad de Sevilla. Grado en Ingeniería Aeroespacia
