Country-specific correlations across Europe between modelled atmospheric cadmium and lead deposition and concentrations in mosses
2012
Previous analyses at the European scale have shown that cadmium and lead concentrations in mosses are primarily determined by the total deposition of these metals. Further analyses in the current study show that Spearman rank correlations between the concentration in mosses and the deposition modelled by the European Monitoring and Evaluation Programme (EMEP) are country and metal-specific. Significant positive correlations were found for about two thirds or more of the participating countries in 1990, 1995, 2000 and 2005 (except for Cd in 1990). Correlations were often not significant and sometimes negative in countries where mosses were only sampled in a relatively small number of EMEP gr…
Increasing Cold Tolerance of Cactus Pear Fruit by High-Temperature Conditioning and Film Wrapping
2017
Pre-storage high-temperature conditioning (HTC, 38 °C, and 95% RH for 24 h) and individual film wrapping (IFW) with a perforated polyolefinic heat-shrinkable film were used as individual treatments or in combination to mitigate chilling injury of first crop cactus pear cv âGiallaâ. The fruit was stored for 21 days at either 2 or 8 °C (CS) plus 1 week of simulated marketing conditions (SMC) at 20 °C. The reduction in peel disorders and decay in HTC-treated fruit stored at 2 °C was comparable to that detected in control fruit stored at 8 °C. IFW was more efficient than HTC in reducing peel disorders, almost completely inhibited weight loss, and preserved freshness in fruit st…
Quality of cactus pear [Opuntia ficus-indica (L.) Mill.] fruit in relation to ripening time, CaCl2 pre-harvest sprays and storage conditions
1999
Abstract Post-harvest behaviour of summer and autumn ripening cactus pear ( Opuntia ficus-indica (L.) Mill. Cactaceae) fruit cv. Gialla was investigated in relation to pre-harvest growing conditions, and CaCl 2 applications. Summer ripening cactus pear fruit were stored for 5 weeks at 6°C and 90–95% relative humidity (RH), and 3 days at 20°C, 75% RH to simulate a marketing period (SMP). Autumn ripening fruits were kept under the same conditions for 7 weeks plus a SMP. Summer ripening cactus pear fruit were more susceptible to chilling injury and to weight loss, but less sensitive to decay than autumn fruit. CaCl 2 delayed rind colour development and increased fruit resistance to decay but p…
Effect of cladode shading on growth and ripening of fruits of cactus pear (Opuntia ficus-indicaL. Miller)
1997
SummaryFruiting cladodes of O. ficus-indica were covered with shade nets at different stages of the fruit development period to study the effect of the time and duration of shade on fruit growth, ripening time and harvest quality. Shading the fruiting cladodes 0, 15 and 30 d after full bloom (DAB) for a period of 15, 30, 45, 60 or 75 d significantly reduced fruit growth and ultimate harvest size. The longer the shading period the greater was the reduction of harvest fruit size. The greatest reduction of fruit growth (30%) occurred when the fruiting cladodes were shaded from bloom to harvest. Differences in growth rate beween fruits on shaded or sunlit cladodes begun to appear at 30 DAB and …
Fresh-cut products from cactus species
2005
Various species of Cactaceae family can serve a source of delicious and healthy fresh foodstuffs. Marketing cacti as ready-to-eat (fresh-cut) products may significantly expand their consumption, on condition that their quality, safety and longevity would answer the market demands. The present work was aimed at studying the storability of fresh-cut products prepared from several edible cactus species and looking for ways to improve their keeping quality. The experiments included fruit of cactus pear Opuntia ficus-indica (L.) Miller, cactus apple (koubo) Cereus peruvianus (L.) Miller, and dragon fruit (pitaya) Hylocereus undatus (Haw.) Britton and Rose, as well as cladodes (pads) of nopal (ve…
Denoising AVIRIS-NG Data for Generation of New Chlorophyll Indices
2021
The availability of Airborne Visible and Infrared Imaging Spectrometer-Next Generation (AVIRIS-NG) data has enormous possibilities for quantification of Leaf Chlorophyll Content (LCC). The present study used the AVIRIS-NG campaign site of Western India for generation and validation of new chlorophyll indices by denoising the AVIRIS-NG data. For validation, concurrent to AVIRIS-NG flight overpass, field samplings were performed. The acquired AVIRIS-NG was subjected to Spectral Angle Mapper (SAM) classifier for discriminating the crop types. Three smoothing techniques i.e., Fast-Fourier Transform (FFT), Mean and Savitzky-Golay filters were evaluated for their denoising capability. Raw and fil…
A multilight approach for documenting and modeling the appearance of large cultural heritage objects
2022
In recent years, Computer Vision has played a major role in the investigation of sur-face appearance, particularly with the introduction of image-based rendering algorithms. Reflectance transformation Imaging (RTI) is one of these approaches. The RTI is a multi-light imaging technique that involves taking a series of images of an item using a stationary camera, while the location of the incident light varies in each photograph. Thanks to the information gathered from this type of acquisition, which is also defined as a Multi-light Image Collection (MLIC), it is possible to model the angular reflectance of a surface. The RTI is frequently employed in the documentation and study of architectu…
Evaluation of Erythema Severity in Dermatoscopic Images of Canine Skin: Erythema Index Assessment and Image Sampling Reliability.
2021
The regular monitoring of erythema, one of the most important skin lesions in atopic (allergic) dogs, is essential for successful anti-allergic therapy. The smartphone-based dermatoscopy enables a convenient way to acquire quality images of erythematous skin. However, the image sampling to evaluate erythema severity is still done manually, introducing result variability. In this study, we investigated the correlation between the most popular erythema indices (EIs) and dermatologists’ erythema perception, and we measured intra- and inter-rater variability of the currently-used manual image-sampling methods (ISMs). We showed that the EIBRG, based on all three RGB (red, green, and blue) channe…
Those Are Lasers That Were Their Eyes
2019
In a Cultural Studies perspective, this essay proposes an intertextual reading of sea-change and representations of the Moor in literature, folklore, visual and decorative arts, and fashion theory studies, as interpreted by William Shakespeare, the artist duo Invernomuto, and fashion designers Dolce & Gabbana.
"Me llaman el desaparecido" : coexistencia y continuidad entre la desaparición forzada y la desaparición social
2020
En este trabajo analizo una de las formas del desborde contemporáneo de la categoría de "desaparición", por la cual ésta pasa a designar formas de invisibilidad, exclusión y violencia muy diferentes a la que definía su marco originario. En particular, me detengo en el trazado de una relación de continuidad entre las formas de la desaparición forzada originaria -ejemplificada en el caso emblemático de la dictadura militar chilena- y las formas de "desaparición social" en las democracias liberales contemporáneas. A partir de la puesta en relación de conceptos políticos como campo, doctrina del shock o excepción, y del análisis de algunos productos culturales, exploramos la posibilidad de habl…
