In Situ Detection of Leakages in Partition Elements through SONAH and Beamforming Techniques

Airborne sound insulation in buildings, whether in fixed partition elements, like partitions or party walls, or mobile elements, like doors or screens, is always related to the performance of the weakest element involved. In situ assessment of airborne sound insulation in building elements can be carried out by pressure techniques or sound intensity techniques. Sound pressure techniques are very quick but fail to discriminate the sound insulation contribution of each building element involved. Sound intensity techniques, on the other hand, allow to determine the sound transmission of each element and also to discriminate indirect transmissions up to a certain degree. In order to find areas with high sound transmission, such as leakages or weakened regions, a large number of measurements on the building element surface have to be performed. Moreover, the sound intensity technique is very time-consuming, because it is necessary to carry out the measurement in each grid point defined. This chapter describes the use of beamforming and SONAH techniques to detect areas with lower airborne sound insulation in a building element. These techniques unify the advantages of both, pressure and sound intensity techniques, allowing the quick visualization of leakages or weakened areas of different building elements

Comunicación Institucional y Prevención de la Violencia de Género. Análisis comparativo entre las webs de la Junta de Castilla y León y del Gobierno Vasco

La desigualdad entre hombres y mujeres heredada históricamente del sistema patriarcal se expresa en la sociedad actual a través de una de sus formas más graves: la violencia de género. Las instituciones públicas ostentan la capacidad suficiente como para generar cambios de perspectiva a través de sus políticas y acercarse así a su definitiva erradicación. Este trabajo se centra en el análisis de la comunicación de tales políticas, desde los canales oficiales en Internet de dos instituciones autonómicas: la Junta de Castilla y León y el Gobierno Vasco.The inequality between men and women inherited historically from the patriarchal system is expressed in today's society through one of its most grave forms: gender violence. Public institutions have the sufficient capacity to generate perspective changes through their policies and to be close in this way to its final eradication.

Blur-specific image quality assessment of microscopic hyperspectral images

Hyperspectral (HS) imaging (HSI) expands the number of channels captured within the electromagnetic spectrum with respect to regular imaging. Thus, microscopic HSI can improve cancer diagnosis by automatic classification of cells. However, homogeneous focus is difficult to achieve in such images, being the aim of this work to automatically quantify their focus for further image correction. A HS image database for focus assessment was captured. Subjective scores of image focus were obtained from 24 subjects and then correlated to state-of-the-art methods. Maximum Local Variation, Fast Image Sharpness block-based Method and Local Phase Coherence algorithms provided the best correlation results. With respect to execution time, LPC was the fastestBlur-specific image quality assessment of microscopic hyperspectral imagespublishedVersio

Marketing de guerrilla y nuevas tendencias de comunicación aplicadas al ámbito deportivo

El marketing de guerrilla y las nuevas tendencias en comunicación, a pesar de haber nacido en la década de los 80´, son unas técnicas poco implantadas en nuestro país y todavía desconocidas para gran parte de la población. En este estudio, a través de una revisión de la literatura actual, el análisis de casos prácticos y la entrevista al director de una agencia de publicidad, se trata de dar a conocer este tipo de publicidad creativa y transgresora, proponiendo un área concreta de aplicación: el ámbito deportivo

The Chihuahua dog: A new animal model for neuronal ceroid lipofuscinosis CLN7 disease?

Neuronal ceroid lipofuscinoses (NCLs) are a group of incurable lysosomal storage disorders characterized by neurodegeneration and accumulation of lipopigments mainly within the neurons. We studied two littermate Chihuahua dogs presenting with progressive signs of blindness, ataxia, pacing, and cognitive impairment from 1 year of age. Because of worsening of clinical signs, both dogs were euthanized at about 2 years of age. Postmortem examination revealed marked accumulation of autofluorescent intracellular inclusions within the brain, characteristic of NCL. Whole-genome sequencing was performed on one of the affected dogs. After sequence alignment and variant calling against the canine reference genome, variants were identified in the coding region or splicing regions of four previously known NCL genes (CLN6, ARSG, CLN2 [=TPP1], and CLN7 [=MFSD8]). Subsequent segregation analysis within the family (two affected dogs, both parents, and three relatives) identified MFSD8:p.Phe282Leufs13*, which had previously been identified in one Chinese crested dog with no available ancestries, as the causal mutation. Because of the similarities of the clinical signs and histopathological changes with the human form of the disease, we propose that the Chihuahua dog could be a good animal model of CLN7 disease

SARS-CoV-2 Infection Among Healthcare Workers in Tijuana, Mexico: A Cross-Sectional Study

Background: Healthcare workers (HCW) are a high-risk group for contraction of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The aim of this study was to estimate the effect size of being a HCW and acquiring coronavirus disease 2019 (COVID-19) at the Mexican Institute of Social Security (IMSS) in Tijuana, Mexico. Methods: A cross-sectional study of the Epidemiologic Surveillance Online Notification System database was conducted, including entries from Tijuana City between March 11, 2020 to May 1, 2020. Multiple imputation was performed for SARS-CoV-2 RT-PCR result where data was missing. Prevalence odds ratios (POR) were calculated to estimate the effect size of HCWs contracting COVID-19 compared to the general population (GP). Results: From a total of 10,216 entries, 6,256 patients were included for analysis. HCW status was significantly associated with higher odds of acquiring COVID-19, (POR=1.730, 95% Confidence Interval [95%CI]=1.459;2.050). Nurses had double odds (POR=2.339, 95%CI=1.804;3.032) than the GP. Physicians had a POR=1.828 (95%CI=0.766;1.380). Resident physician status was double the likelihood of the GP (POR=2.166, 95%CI=0.933;5.025). Meanwhile, being an intern had a protective factor (POR=0.253, 95%CI=0.085;0.758). Among medical specialties, emergency medicine had the highest exposure-effect association, followed by anesthesiologists. Conclusion: HCW had up to 73% increased odds of acquiring COVID-19 than the GP in Tijuana, Mexico. Nurses were the group with the highest likelihood out of all HCW, as a result of prolonged and close contact with patients. Emergency medicine and anesthesiology were the medical specialties with the highest odds of infection because they frequently perform aerosol-generating procedures
