Visual Health Nanocomposites: Present and Future
2021
Background: In recent years, the therapeutics for eye diseases as retinopathy diabetic, dry eye, glaucoma and contact lenses fabrication are including nanocompounds as ocular drug delivery systems, biomarkers for detection of eye diseases, copper and silver ions that has been incorporated by means of the nanotechnology for the production of less toxic and more effective alternatives. Several compounds such as silver nanoparticles, turmeric-based nanocomposites, neovascularization blockers and nanoparticles extracted from the plant Costus pictus among others have been researched for this purpose. Those compounds are some of the promising research efforts that are studying and will contribute…
Changes of the eye optics after iris constriction☆
2010
Purpose: To evaluate the possible change in the optics of the human eye after iris constriction. Methods: Ocular aberrations were measured under natural viewing conditions in 26 eyes. The measured eyes fixated on a dim target while the contralateral eye was either occluded (so the measured eye had a large pupil) or highly illuminated (so the measured eye had a small pupil). The measured eyes fixated to a dim target placed 0.5 D beyond the subject’s far point. Zernike values obtained in both situations were compared within the same pupil diameter corresponding to the one obtained under the high illumination condition. Results: Significant variation in some aberration coefficients were found …
Coloration reflects behavioural types in the convict cichlid, Amatitlania siquia.
2015
9 pages; International audience; Interindividual behavioural differences, consistent over time and across situations, are frequently related to differences in reproductive success, susceptibility to disease and competitive ability. The behavioural phenotype of a conspecific is likely to affect the outcome of a social interaction, so an individual must be able to accurately assess behavioural phenotypes in order to optimize behavioural responses during mate choice, cooperative relationships and agonistic interactions. However, behavioural assessment based on dyadic interactions in different contexts can be costly because it may require significant time, increase the risk of predation and oft…
Internal characteristics of ice-marginal sediments deduced from georadar profiling and sediment properties (Brøgger Peninsula, Svalbard)
2008
Abstract Georadar and sedimentological data were acquired in the Ny-Alesund area on Brogger Peninsula in order to study diamicton in frontal areas of Vestre Broggerbreen and Midre Lovenbreen. Parallel common offset georadar lines were acquired for information on thickness and layering and multioffset measurements served to deduce the subground velocity. Short permafrost cores (
Internal structures and dating of complex zircons from Meissen Massif monzonites, Saxony
1999
Abstract U–Pb zircon ages were determined for accessory zircons from two monzonites from the Meissen Massif (Northern Bohemian Massif, Germany) by SHRIMP ion microprobe. BSE and CL imaging revealed that the monzonite zircons, showing oscillatory growth zoning, often contain inherited cores. Raman microprobe measurements showed that zoned rims (U 277–1426 ppm, Th 144–910 ppm) are slightly disordered to moderately metamict whereas cores have a wide spectrum of structural states, from well-crystallized to highly metamict. The radionuclide (U+Th) content of cores varies from a few hundred to more than 20,000 ppm. SHRIMP ion probe measurements on zoned rims, interpreted as zircon growth during c…
Flow changes and geochemical anomalies in warm and cold springs associated with the 1992-1994 seismic sequence at Pollina, Central Sicily, Italy
2007
During a three-year discontinuous geochemical monitoring of some warm springs and cold discharges located in central-northern Sicily, some hydro-geochemical changes were observed. Excluding a possible related to a moderate seismic activity were accidentally identified. The observed anomalies showed amplitudes that were modulated by the different geometries and volumes of the feeding aquifers. A poroelastic aquifer contraction, a shaking-induced dilatancy theory as well as seismogenetic-induced changes in the properties of the aquifers have been proposed as possible mechanisms for the water flow and hydro-geochemical changes. These preliminary results could be used to design a monitoring net…
Taxonomic Revision of the Genus Trictenotoma Gray, 1832 (Coleoptera: Trictenotomidae). Part 3 – Species from the Philippine Archipelago, with Descrip…
2021
The species of Trictenotoma Grey, 1832 from the Philippine Archipelago are critically assessed, description of T. boudanti Drumont et Telnov sp. nov. from Balabac and Palawan, and a redescription of T. cindarellaKriesche, 1921 from Mindanao are provided. A key to the Philippine Trictenotomidae Blanchard, 1845 is presented for the first time.
G-CLASS: geosynchronous radar for water cycle science – orbit selection and system design
2019
The mission geosynchronous – continental land atmosphere sensing system (G-CLASS) is designed to study thediurnal water cycle, using geosynchronous radar. Although the water cycle is vital to human society, processes on timescalesless than a day are very poorly observed from space. G-CLASS, using C-band geosynchronous radar, could transform this. Itsscience objectives address intense storms and high resolution weather prediction, and significant diurnal processes such assnow melt and soil moisture change, with societal impacts including agriculture, water resource management, flooding, andlandslides. Secondary objectives relate to ground motion observations for earthquake, volcano, and subs…
Mediación policial: Diseño curricular, formación y buenas prácticas en métodos alternativos de resolución de conflictos y gestión emocional
2022
En los últimos tiempos se ha vertido mucha tinta tratando de dar una explicación coherente a la novedosa aparición de la denominada “Mediación Policial” dentro de los denominados métodos adecuados de resolución de conflictos (MARC o ADR en sus siglas en inglés). Este mecanismo está ganando protagonismo en el debate doctrinal y abriéndose camino en la práctica como herramienta capaz de canalizar el potencial transformador de la Justicia restaurativa y de la paz social. En esencia subyace la necesidad de que, en el marco de un Estado Social y democrático de Derecho, las Fuerzas y Cuerpos de Seguridad (FFCCSS) generen confianza en la ciudadanía y obtengan legitimidad para su acción, buscando e…
L’OPACIZZARSI DEL CONFLITTO FRA GIOVANI E ADULTI E L’AFFERMARSI DELLA VIOLENZA FRA PARI
2013
L'ipotesi formulata in questo lavoro riguarda la possibilità che la violenza intra-generazionale ha preso il posto di conflitto intergenerazionale tra i giovani e gli adulti. In altre parole, la violenza non è una modalità di comportamento interpersonale ma il substrato, la base su cui è articolato un insieme complesso di interdipendenze e trasversali azioni e reazioni tra pari. Ne consegue un modello di coesione deviante, che ci permette di affermare che: 1 la violenza esplode senza conflitti o escludendo qualsiasi possibilità di conflitto e della successiva mediazione e negoziazione tra gli attori sono coinvolti nella relazione anzi; 2. La violenza è diventato l'unico "collante" tra giova…
