Comparative evaluation of postoperative pain and periapical healing after root canal treatment using three different base endodontic sealers – A rand…
2022
Abstract Backgroundː Endodontic Sealers come in direct contact with periapical tissue through the apical foramen and lateral canals, influencing the postoperative pain and periapical healing. The aim of the present study was to evaluate and compare postoperative pain and periapical healing after root canal treatment using different base endodontic sealers.Methodsː Primary root canal treatment was initiated in 63 patients diagnosed with necrotic pulp and apical periodontitis, followed by which the endodontic sealers used for obturation were selected based on the random allocation of the participants to the following groups; Tubli-Seal, AH Plus and BioRoot RCS. Postoperative pain was recorded…
Hyperviscosity syndrome in patients with ovarian carcinoma
1998
BACKGROUND In patients with ovarian carcinoma, an hematocrit-independent hyperviscosity syndrome is often present. The syndrome is characterized by normal or low hematocrit and hemoglobin concentration, an elevated platelet count, and an increase in clotting factor turnover. Because deep vein thrombosis (DVT) often complicates the course of ovarian carcinoma, the aim of this study was to investigate the possible association of hyperviscosity syndrome with the development of DVT. METHODS Rheologic estimations of the blood included red blood cell (RBC) aggregation (stasis and low shear), plasma viscosity (pv), blood cell count, and fibrinogen, which were performed before primary surgery and t…
ROS/Gazebo Based Simulation of Co-operative UAVs
2019
UAVs can be assigned different tasks such as e.g., rendez-vous and space coverage, which require processing and communication capabilities. This work extends the architecture ROS/Gazebo with the possibility of simulation of co-operative UAVs. We assume UAV with the underlying attitude controller based on the open-source Ardupilot software. The integration of the co-ordination algorithm in Gazebo is implemented with software modules extending Ardupilot with the capability of sending/receiving messages to/from drones, and executing the co-ordination protocol. As far as it concerns the simulation environment, we have extended the world in Gazebo to hold more than one drone and to open a specif…
Co-operative wineries: Temporal solution or efficient firms? The Spanish case during late Francoism, 1970–1981
2015
Part of economic theory has regarded co-operative firms as useful tools for dealing with market failures during periods of economic contraction, but also as suffering severe efficiency problems during periods of growth. The main aim of this article is to test this hypothesis in the case of Spanish co-operative wineries during the years of late Francoism. In order to do this, the balance sheets of 75 co-operative firms from the 1970s have been subject to financial-ratio analyses. The main conclusion is that these firms were inefficient due to their excessive financial debt. The Spanish Francoist government promoted their creation and granted financial aid – for their value as social and econ…
Developing a conceptual framework for the co-operative and mutual enterprise business model
2018
AbstractThe co-operative and mutual enterprise business model represents a unique type of organisation that has a dual purpose focused on both economic and social goals. For nearly two centuries it has played an important role in economic development, job creation and addressing market failures. However, despite its potential importance to economic development it has been largely ignored within the mainstream economics and management literature. This paper provides an overview of the nature of the co-operative and mutual enterprise business model and also proposes a business model framework or ‘canvas’ that can be used for research, teaching and strategic analysis.
Co-simulation and Formal Verification of Co-operative Drone Control With Logic-Based Specifications
2021
Abstract Unmanned aerial vehicle (UAV) co-operative systems are complex cyber-physical systems that integrate a high-level control algorithm with pre-existing closed implementations of lower-level vehicle kinematics. In model-driven development, simulation is one of the techniques that are usually applied, together with testing, in the analysis of system behaviours. This work proposes a method and tools to validate the design of UAV co-operative systems based on co-simulation and formal verification. The method uses the Prototype Verification System, an interactive theorem prover based on a higher-order logic language, and the Functional Mock-up Interface, a widely accepted standard for co-…
La identidad cooperativa como garantía de futuro: las cooperativas de crédito ante la trivialización de sus principios
2002
Co-operative credit associations have been facing for some time the problem of compatibilising the essential principals which inspire the co-operative movement with the demands of ever more complex and competitive markets. In this context a tendency can be appreciated towards a relaxation of these principals as a means of facing the competitition offered by merchantile companies and adapting themselves to the greater need for stable resources in the form of capital. Under this perspective it is aimed to realise a vision of the problem in the Co-operative credit associations, appreciating two significative cases sucha s Crédit Agricole and the British Building Societies in order to, finally,…
Las peculiaridades de las secciones de crédito de las cooperativas: sus repercusiones en el caso valenciano
1999
El presente artículo tiene por objeto analizar en qué medida las especificidades jurídicas y económicas de las secciones de crédito de las cooperativas condicionan su actividad bancaria. Aunque no tengan consideración de entidades de crédito, estas secciones prestan servicios de depósito, pago y crédito a sus socios. No obstante, las limitaciones existentes para el desarrollo de la actividad crediticia y las especiales características del negocio financiero afectan de forma directa en el desarrollo de estas secciones. Esta serie de condicionantes obliga a prestar especial atención a la vigilancia de estas cooperativas, al igual que se realiza con el conjunto de empresas bancarias, a fin de …
Problemática laboral de los socios trabajadores de las empresas de Economía Social: ¿socios o trabajadores?
1999
Co-operatives and labour societies are the most important organisations within the framework of Social Economy. The establishment of these societies, which create employment in the private sector with a democratic philosophy based on mutual help, has been recently boosted thanks to the support of public power. Their growing importance can be explained by three factors: the Employment Policy, the Social Policy and the productive decentralisation. As far as labour is concerned, these societies offer the following advantages: intensive use of labour, high rate of stability in employment, high levels of productivity, training and surplus re-inversion, lower rate of inflation, fewer conflicts th…
Investigación en el aula: evaluación de la metodología de aprendizaje basado en problemas en la asignatura de Corrosión
2020
[ES] La metodología de Aprendizaje Basado en Problemas (ABP) se introdujo por primera vez en un curso de Corrosión del Master de Ingeniería Química de la Universitat Politècnica de València, durante el curso 2018-2019. Se diseñaron y presentaron diferentes problemas relacionados con todos estos conceptos como metodología de aprendizaje basado en problemas. Para evaluar el empleo de este tipo de metodología activa se plantea la elaboración de una encuesta a los estudiantes de manera anónima e individual y la realización de una matriz de escenarios presentes y futuros para la asignatura de forma grupal. Es importante señalar que a pesar de que para muchos de los estudiantes (67%) esta era la …
