Fourteen-year status report of fatal illnesses in captive chinchilla (Chinchilla lanigera)

Fur ranching has been a prosperous industry for decades. Despite its worldwide distribution, little published information is available regarding the importance of the various causes of death in chinchilla (Chinchilla lanigera). In the period 1999–2013, 698 captive chinchillas from different commercial ranches were presented for necropsy at the Pathology Department (UNLP). Two-hundred and forty-four animals (35.0%) had classical enteritis, 198 (28.4%) had pneumonia, 63 (9.0%) had other infections, 40 (5.7%) had traumatic injuries, 109 (15.6%) had miscellaneous conditions, meanwhile 44 (6.3%) had no significant lesions. Although some disease processes may be underrepresented (i.e. heat stroke and the shock syndrome), the data were collected from a field wide enough and over a sufficient period to give a reliable overview of the fatal problems of this rodent in captivity.Fil: Martino, Pablo Eduardo.

Técnicas de pesca, percepción y manejo de la ictiofauna de la población de San Javier (Santa Fe)

Tesina (Grado en Ciencias Biológicas)--Universidad Nacional de Córdoba. Facultad de Ciencias Exactas, Físicas y Naturales. Lugar de Trabajo: Cátedra de Antropología. Centro de Zoología Aplicada. 2016. 62 h. con Anexos; ils. col.; grafs.; maps.; tabls. Contiene Referencia Bibliográfica.El sistema formado por el río Paraná, sus afluentes y la llanura de inundación cuenta con aproximada- mente 200 especies de peces pertenecientes a 11 órdenes. En sentido ictiogeográfico es una de las regiones con mayor abundancia y diversidad de especies de agua dulce del mundo. Numerosas pobla ciones a lo largo y ancho del río Paraná hacen de la ictiofauna presente su principal recurso para la subsistencia. El conocimiento general de los hábitos de vida y alimentación de los peces es sin duda la herramienta más valiosa para pescar mediante diversas artes de pesca heredadas a lo largo de la historia. En la mayoría de los casos el conocimiento popular coincide plenamente con la literatura científica lo cual a su vez refleja la efectividad y el correcto manejo de la fauna íctica por parte de los pescadores

Polemizando sobre Guinea Ecuatorial y África. Juan Aranzadi, Eugenio Nkogo, Amancio Nsé y Miquel Vilaró

¿Qué es la antropología colonial?, ¿o es anti-colonial?. ¿Qué es el pensamiento afrocéntrico?, ¿o es anti-africano? ¿A quién hay que leer y citar para entender – y ayudar a otros a entender – el pasado precolonial africano: a Cheikh Anta Diop o a E. E. Evans-Pritchard? O en el caso del pasado colonial y poscolonial: ¿a Frantz Fanon o a Georges Balandier, a Marshall Sahlins o a Stokely Carmichael, a Mudimbe, Hountondji y Appiah o a Césaire, Senghor y Nkrumah? Respondiendo a los desafíos y a las contradicciones del mundo Africano que estudian y reflexionando críticamente sobre su propia práctica y las formas de abordar este pasado, antropólogos, filósofos e historiadores dentro y fuera de la academia española han dedicado recientemente una nueva atención al estudio de Guinea Ecuatorial y África. Esta clase magistral, reúne a dos de los más eminentes intelectuales que trabajan en este campo – Juan Aranzadi y Eugenio Nkogo – para debatir, en un formato polémico, algunas de las propuestas afirmativas y contestaciones lanzadas por el estudio de Juan Aranzadi titulado “Hacia un replanteamiento radical de los estudios sobre Guinea Ecuatorial” publicado en los volúmenes colectivos Guinea Ecuatorial (des)conocida. Lo que sabemos, ignoramos, inventamos y deformamos acerca de su pasado y su presente, editados por el Centro de Estudios Afro-Hispánicos (CEAH) de la UNED en 2020.

Eliciting smile and laughter during intraoperative electrical stimulation of the cingulum: Surgical scenario

Laughter has a major role in daily social interactions; consequently, its biologic bases have been previously studied. Nevertheless, its cerebral representation remains unclear. The most accepted hypothesis has postulated that laughter has 2 components: mirth, related to the temporal and frontal neocortical areas, and motor aspect, related to the limbic system and brainstem. Furthermore, in prior studies, laughter has been elicited during electric stimulation with depth electrodes in the supplementary motor area and the cingulum. This Video 1 reports resection of a right superior frontal gyrus diffuse astrocytoma (isocitrate dehydrogenase mutant, World Health Organization grade II) with awake intraoperative electric cortical and subcortical stimulation mapping. Diffusion tensor imaging (DTI) tractography, including all the tracts in relation to the tumor, was obtained preoperatively and postoperatively. Stimulation of the cingulum medially and inferiorly to the tumor elicited a patient's smile and laugh without mirth or merriment. Also, this point correlated with the reconstructed cingulum in the intraoperatively navigated DTI tractography. In conclusion, these findings support the anatomic subdivision of the laughter's mechanism and the role of the cingulum in its motor component. Furthermore, smiles and laughter could be useful functional landmarks to identify the cingulum during subcortical mapping. Although it remains unclear whether pursuing resection beyond this point would have caused permanent postoperative deficits, considering laughter's role in social interaction and other emotion-processing functions associated with the cingulum, in the future it could be potentially considered a functional limit of the resection of intrinsic tumors

Experiencia comparativa de tres híbridos de maíz dulce de ciclo corto en Los Antiguos, Santa Cruz

Resulta importante evaluar el desarrollo y productividad de híbridos de maíz dulce de ciclo corto en zonas templado-frías, como el valle de Los Antiguos, que a diferencia de otras localidades de la provincia, presenta un ambiente (suelo, clima, disponibilidad de agua) favorable para el desarrollo de la producción hortícola a escala comercial, a la intemperie, durante los meses estivales. Este trabajo busca entonces realizar una experiencia comparativa de los resultados productivos obtenidos con tres híbridos de maíz dulce de ciclo corto, para generar información que le permita a los productores hortícolas elegir la mejor opción al momento de incorporar este cultivo.EEA Santa CruzFil: Arhancet, Juan Santiago.

Lumped Element Kinetic Inductance Detectors for space applications

Kinetic Inductance Detectors (KID) are now routinely used in ground-based telescopes. Large arrays, deployed in formats up to kilopixels, exhibit state-of-the-art performance at millimeter (e.g. 120-300 GHz, NIKA and NIKA2 on the IRAM 30-meters) and sub-millimeter (e.g. 350-850 GHz AMKID on APEX) wavelengths. In view of future utilizations above the atmosphere, we have studied in detail the interaction of ionizing particles with LEKID (Lumped Element KID) arrays. We have constructed a dedicated cryogenic setup that allows to reproduce the typical observing conditions of a space-borne observatory. We will report the details and conclusions from a number of measurements. We give a brief description of our short term project, consisting in flying LEKID on a stratospheric balloon named B-SIDE.Comment: To appear in the SPIE 2016 Proceeding

Visual performance after the deterioration of retinal image quality: induced forward scattering using Bangerter foils and fog filters

We induced and evaluated different levels of retinal-image degradation using Bangerter foils and fog filters. We found increased straylight and an important deterioration in visual performance, assessed by means of visual acuity, contrast threshold, and visual discrimination capacity. Bangerter foils induced forward scattering levels comparable to those observed in mature to severe cataracts, with an important impact of halos and starbursts. Fog filters induced lower levels of intraocular scattering, although luminous veils and circular halos were reported. The visual disturbance index positively correlated with intraocular scattering and straylight. Our results show retinal-image quality has an important influence on night-vision performance.Ministerio de Economía y Competitividad 10.13039/501100003329 (FIS2017-85058-R

Changes in Visual Performance under the Effects of Moderate–High Alcohol Consumption: The Influence of Biological Sex

The purpose of this study was to analyze the changes in visual functions under the effects of moderate–high breath alcohol concentrations (BrACs), and the influence of biological sex on visual deterioration, considering different factors. A total of 37 healthy habitual alcohol users were enrolled in the experiment. The participants underwent a baseline session and a second session after an intake of 450 mL of red wine, so that all of them reached a BrAC above 0.25 mg/L. Visual performance was assessed by measuring the contrast sensitivity function, the halo perception, the stereopsis, and finally the retinal image quality. A Visual Deterioration Score (VDS) was calculated using the deterioration of these visual variables. All visual functions analyzed were significantly impaired following alcohol consumption (p < 0.05). The VDS was associated with the BrAC (ρ = −0.476). The VDS was also significantly higher in females, with the BrAC having a significant effect on the variability of the VDS in males and females (p 0.05). Visual functions were significantly impaired under the influence of alcohol, and this deterioration was greater in females. The deterioration depends on the BrAC reached, being the primary thing responsible for the differences observed between males and females.Ministry of Economy and Competitiveness (Spain)European Regional Development Fund (ERDF) (FIS2017-85058-R

Funding for open access charge: Universidad de Granada/Consorcio de Bibliotecas Universitarias de Andalucia (CBUA).Purpose: Cannabis is the most widely consumed illicit drug worldwide. It has been suggested that cannabis could generate blurred vision during reading tasks. The goal of this study was to objectively assess the acute effects of smoking cannabis on the dynamics of ocular accommodation. The influence of other factors, including target distance and the direction of accommodation, as well as personal characteristics, were also analysed. Methods: Nineteen young people who were occasional cannabis users participated in the study (mean age 22.53 [3.12] years). Their usage profiles were evaluated by means of the Cannabis Use Disorders Identification Test-revised (CUDIT-r). The dynamics of the accommodative response were evaluated using an open-field auto refractor (Grand Seiko WAM-5500). The participants completed two different experimental sessions, one week apart, and in random order (baseline session and after smoking cannabis). During these sessions, the amplitude of the response (D), mean velocity (D/s), peak velocity (D/s), response time (s), accommodative lag (D) and accommodation variability (D) were measured. Results: The results indicated that cannabis use had a significant main effect on the mean accommodation/disaccommodation velocity (F1,13 = 7.21; p = 0.02; η 2 p = 0.396). Cannabis consumption also interacted significantly with other factors. Response time showed a significant two-way interaction between condition × target distance (F1,13 = 11.71; p = 0.005; η 2 p = 0.474) and condition × accommodation direction (F1,13 = 8.71; p = 0.01; η 2 p = 0.401). For mean velocity, two-way interactions were found between condition × age (F1,13 = 6.03; p = 0.03; η 2 p = 0.354), condition × CUDIT-r score (F1,13 = 6.03; p = 0.03; η 2 p = 0.356) and condition × target distance (F1,13 = 7.20; p = 0.02; η 2 p = 0.396). Conclusions: These findings suggest that cannabis use can alter the accommodation process, although further studies should be carried out to explore the role of attention deficits. According to these results, certain daily activities that depend on an accurate accommodative function may be affected by cannabis use.Ministry of Economy and Competitiveness (Spain)European Commission FIS2017-85058-RMinistry of Science, Innovation and Universities (Spain) FPU15/05571Universidad de Granada/Consorcio de Bibliotecas Universitarias de Andalucia (CBUA

On the use of information and infrastructure technologies for the smart city research in Europe: a survey

The Smart City paradigm has become one of the most important research topics around the globe. Particularly in Europe, it is considered as a solution for unstoppable increase of high density urban environments and the European Commission has included the Smart City research as one of the key objectives for the FP7 (Seventh Framework Program) and H2020 (Horizon 2020) research initiatives. As a result, a considerable amount of quality research, with particular emphasis on information and communication technologies, has been produced. In this paper, we review the current efforts dedicated in Europe to this research topic. Particular attention is paid in the review to the platforms and infrastructure technologies adopted to introduce the Internet of Things into the city, taking into account the constraints and harshness of urban environments. Furthermore, this paper also considers the efforts in the experimental perspective, which includes the review of existing Smart City testbeds, part of wider European initiatives such as FIRE (Future Internet Research and Experimentation) and FIWARE. Last but not least, the main efforts in providing interoperability between the different experimental facilities are also presented.This work was funded in part by the European Union’s Horizon 2020 Programme of the FESTIVAL project (Federated Interoperable Smart ICT Services Development and Testing Platforms) under grant agreement 643275, and from the Japanese National Institute of Information and Communications Technology
