RESUMO
This study is a fingerprint comparison of the friction skin detail observed on fingers appearing in ten photographs requested by the Historic Heritage Brigade. These photographs had been uploaded to an online marketplace and show a hand holding different archaeological pieces that had allegedly been stolen. After the ten images had been digitally optimized, seven were determined to contain sufficient clear and continuous ridge detail for the purpose of fingerprint comparison and search. These imprints were compared to the fingerprints of the subject under investigation. Four of them were matched to the index finger, two with the middle finger and one with the ring finger, all from the left hand. These fingerprints were also entered into the Spanish Automated Fingerprint Identification System, resulting in a match to the individual under investigation by the Judicial Police Group.

During the last few years, abandoned object detection has emerged as a hot topic in the video-surveillance community. As a consequence, a myriad of systems has been proposed for automatic monitoring of public and private places, while addressing several challenges affecting detection performance. Due to the complexity of these systems, researchers often address independently the different analysis stages such as foreground segmentation, stationary object detection, and abandonment validation. Despite the improvements achieved for each stage, the advances are rarely applied to the full pipeline, and therefore, the impact of each stage of improvement on the overall system performance has not been studied. In this paper, we formalize the framework employed by systems for abandoned object detection and provide an extensive review of state-of-the-art approaches for each stage. We also build a multi-configuration system allowing one to select a range of alternatives for each stage with the objective of determining the combination achieving the best performance. This multi-configuration is made available online to the research community. We perform an extensive evaluation by gathering a heterogeneous dataset from existing data. Such a dataset allows considering multiple and different scenarios, whereas presenting various challenges such as illumination changes, shadows, and a high density of moving objects, unlike existing literature focusing on a few sequences. The experimental results identify the most effective configurations and highlight design choices favoring robustness to errors. Moreover, we validated such an optimal configuration on additional datasets not previously considered. We conclude the paper by discussing open research challenges arising from the experimental comparison.
RESUMO
Bronchiectasis occurred naturally in 12-month-old spontaneously diabetic eSS male rats. The lungs of 3 and 6-month-old eSS rats were compared in eumetabolic eSS rats from three inbred lines consisting of inbred spontaneously diabetic eSS derived from IIM strain; these were compared with eumetabolic, outbred Wistar rats, paired by sex and age. Acrylic casts of bronchial tree were obtained after injection of a plastic substance. The casts were pruned to focus on the first four bronchial branchings. Diameter and volume of the conductive bronchial tree were determined using a binocular magnifier. Histological sections were obtained. All lines showed multiple bronchiectasis, mostly fusiform, bronchial dilatation and inflammatory response with lymphocytic infiltrates. These symptoms were much more severe in 180-day-old eSS males. Bacteria were isolated from the lungs in 70% of cases (n = 32), except in eSS rats. Pseudomonas spp. (38%) and Gram-positive cocci as coagulase-negative Staphylococcus spp. (20%) were detected. Neither pathogenic bacteria nor saprophyte fungi were found. Although all lines were affected, diabetes in eSS appears to be an aggravating factor.

Ante la aparición espontánea de bronquiectasias en ratas macho eSS diabéticas, se examinaron los pulmones de ratas eSS de 3 a 6 meses de edad y los de ratas eumetabólica de tres líneas: eSS endocriada con diabetes espontánea tipo 2 derevida de la cepa IIM; líneas e, m y alfa endocriadas, y Wistar eumetabólica y exocriada, agrupadas según sexo y edad. Se obtuvieron moldes se recortaron y se concentró la observación en las primeras cuatro ramificaciones bronquiales; se determinaron el diámetro y el volumen con la lente binocular de aumento. Además, se obtuvieron cortes histológicos. Aunque en todas las líneas se observaron bronquiectasias múltiples, principalmente fusiformes, la dilatación bronquial y la respuesta inflamatoria con los infiltrados linfocíticos fueron mucho más graves en los machoos eSS de 180 días de edad. En el 70 por ciento de los casos (n=32) se aislaron bacterias en los pulmones, excepto en las ratas eSS. Se detectaron Pseudomona spp. (38 por ciento) y cocos Gram positivos en forma de Staphylococcus spp. coagulasa negativos (20 por ciento). No se encontraton hongos patógenos ni saprofíticos. Si bien todas las líneas aparecen afectadas, la diabetes de eSS sería un factor agravante

Se investigaron a través de estudios anatómicos, biomecánicos y electromiográficos comparativos, en flexión y extensión, las fuerzas musculares actuantes en el complejo codo-antebrazo. Se trata de indagar a través de los mismos cual sería a priori la posición en que dichas fuerzas estabilizan el sector estudiado. Resultante de ellos, se comprueba la influencia del biceps como estabilizador de la extremidad proximal, anulando las fuerzas rotatorias en dicho sector. Dicho efecto se ejerce únicamente en extensión y supinación

Aún no está dicha la última palabra en el tratamiento de las fracturas laterales de la cadera. Tampoco creemos que éstas lo sean. En la experiencia lograda con nuestro sistema de fijación, que en el año 1981 mereciera el premio de la Universidad Nacional de Rosario por su diseño y pruebas de resistencia, pretendemos aportar una contribución para la solución de las mismas
