Estudio comparativo de los parámetros acústicos de la norma UNE-EN ISO 3382-1 medidos con fuente puntual y con el sistema de refuerzo sonoro en salas de cine

El objetivo principal de este trabajo fin de máster es la obtención de los parámetros acústicos, que especifica la norma UNE-EN ISO 3382-1, con una fuente omnidireccional y con cada uno de los canales del sistema de refuerzo sonoro (Izquierdo, Central, Derecho, Surround Izquierdo y Surround Derecho) en una sala de cine, así como la comparación de los resultados. La sala estudiada es la sala 6 de Kinepolis, que está situada en Pozuelo de Alarcón (Madrid). Es una sala de gran tamaño (8800 m3) que cuenta con 706 butacas. Tras un estudio de la situación actual en la investigación de acústica de salas, se han realizado las mediciones de la respuesta al impulso con las distintas fuentes y con dos tipos de señal: Secuencias de Máxima Longitud (Maximum Length Sequence - MLS) y barridos sinusoidales. Además, se ha creado un modelo virtual de la sala con el software EASE (Enhanced Acoustic Simulator for Engineers). Los tiempos de reverberación son bastante bajos (aproximadamente 0,6 s en frecuencias medias) y los parámetros subjetivos indican gran definición y claridad. C80 es mayor a 10 dB para casi todas las bandas de frecuencia y D50 es superior a 0,8. Con los datos obtenidos de las mediciones y la simulación se ha realizado un estudio comparativo en el que se incluye información acerca de cómo varían los parámetros acústicos en función del tipo de fuente utilizada, la fiabilidad del modelo creado o la calidad acústica de la sala. Además, presenta la posibilidad de realizar la medición de algunos de los parámetros acústicos con los altavoces del sistema de refuerzo sonoro, teniendo en cuenta las mejoras de los parámetros subjetivos con los altavoces de pantalla. ABSTRACT. The main objective of this Master's Dissertation is to measured some acoustic parameters, which are specified in UNE-EN ISO 3382-1, with an omnidirectional source and each channel sound reinforcement system (Left, Center, right, Surround Left and Surround Right) in a movie theater, and the comparison of results. The analyzed room is Kinepolis' room 6, which is placed in Pozuelo de Alarcón (Madrid). It is a large room (8800 m3) which has 706 seats. After the state of the art in room acoustics research, room's impulse responses have been measured with two types of signal: Maximum Length Sequence (MLS) and Logarithmic Frequency Sine Sweep. In addition, a virtual model of the room has been created with EASE software (Enhanced Acoustic Simulator for Engineers). Reverberation times are quite low (about 0.6 s at mid frequencies) and subjective parameters indicate high definition and clarity. C80 is greater than 10 dB for almost all frequency bands and D50 is greater than 0.8. The data obtained from both the measurements and the simulation has been analyzed in order to include a comparative study with information about the acoustic parameters variation depending on the type of acoustic source, the reliability of the model created or the acoustic quality of the room. Furthermore, it presents the possibility of measuring some acoustical parameters with sound reinforcement system, taking into account improvements in subjective parameters when you are measuring with screen channels.

Service for the pseudonymization of electronic healthcare records based on ISO/EN 13606 for the secondary use of information

The availability of electronic health data favors scientific advance through the creation of repositories for secondary use. Data anonymization is a mandatory step to comply with current legislation. A service for the pseudonymization of electronic healthcare record (EHR) extracts aimed at facilitating the exchange of clinical information for secondary use in compliance with legislation on data protection is presented. According to ISO/TS 25237, pseudonymization is a particular type of anonymization. This tool performs the anonymizations by maintaining three quasi-identifiers (gender, date of birth and place of residence) with a degree of specification selected by the user. The developed system is based on the ISO/EN 13606 norm using its characteristics specifically favorable for anonymization. The service is made up of two independent modules: the demographic server and the pseudonymizing module. The demographic server supports the permanent storage of the demographic entities and the management of the identifiers. The pseudonymizing module anonymizes the ISO/EN 13606 extracts. The pseudonymizing process consists of four phases: the storage of the demographic information included in the extract, the substitution of the identifiers, the elimination of the demographic information of the extract and the elimination of key data in free-text fields. The described pseudonymizing system was used in three Telemedicine research projects with satisfactory results. A problem was detected with the type of data in a demographic data field and a proposal for modification was prepared for the group in charge of the drawing up and revision of the ISO/EN 13606 norm.

Isolation and one-step preparation of A2E and iso-A2E, fluorophores from human retinal pigment epithelium

Age-related macular degeneration, a major cause of blindness for which no satisfactory treatments exist, leads to a gradual decrease in central high acuity vision. The accumulation of fluorescent materials, called lipofuscin, in retinal pigment epithelial cells of the aging retina is most pronounced in the macula. One of the fluorophores of retinal pigment epithelial lipofuscin has been characterized as A2E, a pyridinium bis-retinoid, which is derived from two molecules of vitamin A aldehyde and one molecule of ethanolamine. An investigation aimed at optimizing the in vitro synthesis of A2E has resulted in the one-step biomimetic preparation of this pigment in 49% yield, readily producing more than 50 mg in one step. These results have allowed for the optimization of HPLC conditions so that nanogram quantities of A2E can be detected from extracts of tissue samples. By using 5% of the extract from individual aged human eyes, this protocol has led to the quantification of A2E and the characterization of iso-A2E, a new A2E double bond isomer; all-trans-retinol and 13-cis-retinol also have been identified in these HPLC chromatograms. Exposure of either A2E or iso-A2E to light gives rise to 4:1 A2E:iso-A2E equilibrium mixtures, similar to the composition of these two pigments in eye extracts. A2E and iso-A2E may exhibit surfactant properties arising from their unique wedge-shaped structures.

Function of the p86 subunit of eukaryotic initiation factor (iso)4F as a microtubule-associated protein in plant cells.

The isozyme form of eukaryotic initiation factor 4F [eIF-(iso)4F] from wheat germ is composed of a p28 subunit that binds the 7-methylguanine cap of mRNA and a p86 subunit having unknown function. The p86 subunit was found to have limited sequence similarity to a kinesin-like protein encoded by the katA gene of Arabidopsis thaliana. Native wheat germ eIF-(iso)4F and bacterially expressed p86 subunit and p86-p28 complex bound to taxol-stabilized maize microtubules (MTs) in vitro. Binding saturation occurred at 1 mol of p86 per 5-6 mol of polymerized tubulin dimer, demonstrating a substoichiometric interaction of p86 with MTs. No evidence was found for a direct interaction of the p28 subunit with MTs. Unlike kinesin, cosedimentation of eIF-(iso)4F with MTs was neither reduced by MgATP nor enhanced by adenosine 5'-[gamma-imido]triphosphate. Both p86 subunit and p86-p28 complex induced the bundling of MTs in vitro. The p86 subunit was immunolocalized to the cytosol in root maize cells and existed in three forms: fine particles, coarse particles, and linear patches. Many coarse particles and linear patches were colocalized or closely associated with cortical MT bundles in interphase cells. The results indicate that the p86 subunit of eIF-(iso)4F is a MT-associated protein that may simultaneously link the translational machinery to the cytoskeleton and regulate MT disposition in plant cells.

Foi, também, incluído no trabalho exemplo prático da documentação básica resultante da implementação na empresa EXEMPLO. A sistemática e modelos desenvolvidos, bem como a visualização de um exemplo prático, podem auxiliar as empresas a diminuir significativamente o tempo de implementação, embora ajustes devam ser feitos para adequação à sua realidade. Os ajustes necessários devem considerar os requisitos regulamentares, dependendo do tipo de produto e do órgão regulatório responsável pela sua regulamentação e fiscalização, bem como requisitos estatutários que possam impactar na sistemática desenvolvida.

Benefits of the ISO 9001 and ISO 14001 standards: a literature review

Purpose: The purpose of this paper is to determine the similarities and differences between the benefits derived from implementing the ISO 9001 and the ISO 14001 standards. Methodology/Approach: The paper reviews the literature using an electronic search in the ScienceDirect, ABI/Inform, Emerald databases to identify papers focusing on the adoption of the ISO 9001 and 14001 standards and the benefits derived from implementing them. Findings: The paper identifies 82 articles about ISO 9001 and 29 about ISO 14001. Although some differences can be observed between the benefits considered by ISO 9001 and 14001, there is a great degree of coincidence in the benefits studied. The review suggests 13 benefits as the most usually analyzed (including environmental performance for the case of the ISO 14001 standard) by scholars. It is suggested that both standards have clear benefits on operational, people and customer results and that the effects on financial performance are inconclusive. Limitations/implications: One limitation of this paper is that the works identified are conditioned by the search strategy used. In addition, other key words could be included in future studies such as operational, market, quality, financial performance, and customer satisfaction in order to expand this search. Originality/Value: The main contribution is that the paper identifies the literature gap and future research proposals with regard to the benefits of the ISO 9001 and ISO 14001 standards.

Compilation of results of the STRATAGEM project as ISO-image of the final CD-ROM

The study of the Neogene (Miocene to Holocene) stratigraphic record on the glaciated Atlantic margin of NW Europe has, to date, largely been undertaken on an ad-hoc basis. Whereas a systematic approach to understanding the stratigraphic development of Palaeogene and older strata has been undertaken in areas such as the North Sea, West of Shetland and Norway, the problem of establishing a Neogene framework has been only partly addressed by academia and the oil industry. In most cases where a Neogene stratigraphy has been constructed, this has been largely in response to problem solving and risk assessment in a restricted area. Nevertheless, in the past few years it has become increasingly apparent that there is a common history in the Neogene development of the passive Atlantic margin of NW Europe, between mid-Norway and SW Ireland. The inspection and interpretation of an extensive geophysical and geological database has identified several regionally significant and correlatable unconformities along this continental margin. Thus, a regional approach to the stratigraphical development of the Neogene succession on the glaciated European Atlantic margin is undertaken in this volume.

Results of a sediment profile and water analyses from Lake Hancza in northeastern Poland

We investigated the sedimentary record of Lake Hancza (northeastern Poland) using a multi-proxy approach, focusing on early to mid-Holocene climatic and environmental changes. AMS 14C dating of terrestrial macrofossils and sedimentation rate estimates from occasional varve thickness measurements were used to establish a chronology. The onset of the Holocene at c. 11600 cal. a BP is marked by the decline of Lateglacial shrub vegetation and a shift from clastic-detrital deposition to an autochthonous sedimentation dominated by biochemical calcite precipitation. Between 10000 and 9000 cal. a BP, a further environmental and climatic improvement is indicated by the spread of deciduous forests, an increase in lake organic matter and a 1.7% rise in the oxygen isotope ratios of both endogenic calcite and ostracod valves. Rising d18O values were probably caused by a combination of hydrological and climatic factors. The persistence of relatively cold and dry climate conditions in northeastern Poland during the first one and a half millennia of the Holocene could be related to a regional eastern European atmospheric circulation pattern. Prevailing anticyclonic circulation linked to a high-pressure cell above the retreating Scandinavian Ice Sheet might have blocked the influence of warm and moist Westerlies and attenuated the early Holocene climatic amelioration in the Lake Hancza region until the final decay of the ice sheet.
