Quantitative Multispectral Imaging Differentiates Melanoma from Seborrheic Keratosis.
2021
Melanoma is a melanocytic tumor that is responsible for the most skin cancer-related deaths. By contrast, seborrheic keratosis (SK) is a very common benign lesion with a clinical picture that may resemble melanoma. We used a multispectral imaging device to distinguish these two entities, with the use of autofluorescence imaging with 405 nm and diffuse reflectance imaging with 525 and 660 narrow-band LED illumination. We analyzed intensity descriptors of the acquired images. These included ratios of intensity values of different channels, standard deviation and minimum/maximum values of intensity of the lesions. The pattern of the lesions was also assessed with the use of particle analysis. …
Differentiation of seborrheic keratosis from basal cell carcinoma, nevi and melanoma by RGB autofluorescence imaging
2018
A clinical trial on the autofluorescence imaging of skin lesions comprising 16 dermatologically confirmed pigmented nevi, 15 seborrheic keratosis, 2 dysplastic nevi, histologically confirmed 17 basal cell carcinomas and 1 melanoma was performed. The autofluorescence spatial properties of the skin lesions were acquired by smartphone RGB camera under 405 nm LED excitation. The diagnostic criterion is based on the calculation of the mean autofluorescence intensity of the examined lesion in the spectral range of 515 nm–700 nm. The proposed methodology is able to differentiate seborrheic keratosis from basal cell carcinoma, pigmented nevi and melanoma. The sensitivity and specificity of the prop…
A method for skin malformation classification by combining multispectral and skin autofluorescence imaging
2018
As the incidence of skin cancer is still increasing worldwide, there is a high demand for early, non-invasive and inexpensive skin lesion diagnostics. In this article we describe and combine two skin imaging methods: skin autofluorescence (AF) and multispectral criterion p’. To develop this method, we used custom made prototype with 405 nm, 526 nm, 663 nm and 964 nm LED illuminations, perpendicular positioned linear polarizers, 515 nm filter and IDS camera. Our aim is to develop a skin lesion diagnostic device for primary care physicians who do not have experience in dermatology or skin oncology. In this study we included such common benign lesion groups as seborrheic keratosis, hyperkerato…
'Coros y Danzas de la Sección Femenina' política y folklore
2003
Els "Coros y Danzas" de la Sección Femenina de Falange presentaven una intencionalitat política a l'hora de recuperar el folklore, utilitzant-lo amb una finalitat propagandística i legitimadora del discurs de la unitat d'Espanya. Més enllà d'una recuperació i una investigació etnogràfica, que preservara els arrels tradicionals, les falangistes unificaven vestimentes i les adaptaven a les seues pròpies necessitats, fent d'aquesta organització una de les més eficaces per l'educació informal de les dones durant el franquisme
La formació professional de les dones: la ventafocs del sistema educatiu (València 1951-1970)
1999
Les dones valencianes, igual que la major part de les de la resta de l'Estat, malgrat la seua cada vegada major incorporació al món productiu al llarg dels anys 50 i 6o del segle XX, van rebre una formació professional primordialment en mans de la Sección Femenina i l'esglèsia catòlica, les dues institucions que donaven suport al franquisme. Es tractava d'una formació que perpetuava la triple segregació del món laboral, mantenint les especialitats femenines, no potenciant-ne l'especialització, formant-les per als oficis menys remunerats, i continuant la preparació per les tasques domèstiques.
INTIMIDAD DEL TRABAJADOR Y COMUNICACIONES ELECTRÓNICAS SEGÚN EL TRIBUNAL CONSTITUCIONAL
2016
El Tribunal Constitucional ha desempeñado un importante papel en la ponderación de los intereses enfrentados en supuestos en los que la utilización de tecnologías de la información y la comunicación en la empresa somete a examen los lindes entre el respeto a los derechos fundamentales de los trabajadores y las facultades legítimas de dirección, control y organización del empleador. El objeto de este artículo es analizar la doctrina del Tribunal Constitucional en el estudio de una de las manifestaciones concretas de la implantación generalizada de las tecnologías de la información y comunicación en la empresa, la utilización masiva de medios de comunicación electrónica como medio de comunic…
Second Opinion System for Intraoral Lesions
2014
In this paper we present the prototype of a teledentistry system to perform the remote diagnosis of oral diseases. It makes use of a particular device called intra-oral (or dental) camera properly designed to shoot video and take pictures of the inner part of the mouth. The intra-oral cameras can be connected via USB to a common PC and they are very cheap, unlike the intra-oral photography kit for DSLR cameras. Usually this kind of devices are used in dentistry studies for local visualization by means of specialized software. The novelty of our system is that the real-time video produced by this device is canalized into a video streming by means of Video LAN client server (VLC) and pictures…

Occurrence of the lessepsian species Portunus segnis (Crustacea: Decapoda) in the Gulf of Gabes (Tunisia): First record and new information on its bi…
2015
The alien blue swimming crab, Portunus segnis (Forskal, 1775), an Indo-Pacific species has been recorded in the Southern Mediterranean Sea since decades, even if its occurrence along the Tunisian coasts was not recorded yet. This paper reports the first record of P. segnis in the Gulf of Gabes, south-eastern Tunisia, with few observations on its biology and ecology. Twenty-four females of P. segnis were accidentally caught by local fishermen in October 2014 in shallow sandy areas covered mostly by seagrass and algal beds. Among these 24 individuals, 14 specimens (58.33%) were ovigerous. The mean carapace length (CL) and width (CW) of ovigerous females were 143.0 +/- 5.8 mm and 67.8 +/- 3.6 …
Effect of salinity and temperature on feeding physiology and scope for growth of an invasive species (Brachidontes pharaonis - MOLLUSCA: BIVALVIA) wi…
2008
Abstract The Indo-Pacific mytilid Brachidontes pharaonis (Bivalvia, Fischer 1870) offers an excellent model for the study of “Lessepsian migration” and the successive colonization at new Mediterranean locations. This species in out competing indigenous bivalves is particularly well adapted to Mediterranean conditions and this is likely due to biological characteristics and physio-ecological plasticity. In the present paper, we report on clearance rate (CR), respiration rate (RR) and Scope for Growth (SFG) of B. pharaonis collected from a Western Sicilian pond (Southern Tyrrhenian, MED). Physiological variables were determined in response to a range of temperatures from 11 ° to 20 °C and a b…
