No full textDeficit irrigation and maturation stage influence quality and flavonoid composition of ‘Valencia’ orange fruit
Full text linkBACKGROUND:Effects of continuous deficit irrigation (DI) and partial rootzone drying (PRD) treatments (50%ETc) in comparison
with full irrigation (CI, 100% ETc) were investigated during ‘Valencia’ orange fruit maturation. Ultra-high-performance liquid
chromatography/high-resolutionmass spectrometry was used to quantify hesperidin, narirutin, tangeritin, nobiletin, didymin
and neoeriocitrin in the fruit juice and peel.
RESULTS: No significant effect of irrigation was found on yield, juice soluble solids or acidity. Juice color was not influenced
by irrigation or harvest date, whereas peel color increased during maturation and was more pronounced in CI and PRD fruits.
Juice acidity reached a peak in May, while soluble solids increased linearly throughout maturation. Hesperidin was the major
flavanone detected during maturation, with concentrations 200-fold higher in the fruit peel than in the juice. In the peel,
narirutin, didymin and neoeriocitrin decreased while hesperidin, nobiletin and tangeritin increased with maturation. Narirutin
synthesis in the orange fruit was insensitive to irrigation strategy. In fruit peels, PRD and DI induced the decline of hesperidin,
nobiletin and tangeritin only in June, whereas in the juice, deficit irrigation treatments induced an increase in hesperidin and
didymin.
CONCLUSION: These results suggest that deficit irrigation, in particular the conditions imposed with PRD, may cause a
significant accumulation shift of total flavonoids from the fruit peel into the juice, with a positive impact on juice quality and
nutritional value. Fruit compositional changes during maturation also suggest that late harvest can improve fruit palatability
and nutritional quality under the cultural and environmental conditions of this study
The construction of Karen Karnak: The multi-author-function
No full textThis thesis is situated within the comparatively recent developments of Web 2.0 and the emergence of interactive WikiMedia, and explores the mode of authorship within a Read/Write culture compared to that of a Read/Only tradition. The hypothesis of this study is that the role of the audience has become merged with the author, and as such, represents new functions and attributes, distinct from a more conventional concept of authorship, in which the roles of audience and author are more separate. Read/Write and participatory culture, as defined by this study, is focused on collaboration, and includes the influences of D.I.Y. culture, Open-Source practices and the production of text by multiple authors. Multi-authorship presents a re-thinking of several concepts which support the notion of the individual author, since the focus of multi-authorship is not on attribution and ownership of a finished text, but on the continued malleability of a text. Modes of multi-authorship, demonstrated in the use of the pseudonyms Alan Smithee and Karen Eliot, represent declarative authors whose names signify multiple origins, whilst concurrently indicating a distinct body of work. The function of these names form an important context to this study, since primary research involves the construction of an experimental mode of multi-authorship utilising WikiMedia technology and the interaction of thirty nine participants, who are invited to create a body of work under the collective pseudonym Karen Karnak. The data generated by this experiment is analysed using aspects of Michel Foucault's author-function to identify and determine power structures inherent in the WikiMedia context. The interplay of power structures, including concepts such as identity, ownership and the body of work, affect the resulting mode of authorship and contribute to the construction of Karen Karnak, suggesting further areas of research into the emerging multi-author
Turismo
No full textLo scritto analizza l'attuale assetto delle competenze sul turismo alla luce del vigente art. 117 Cost. La definizione della materia e la ricaduta della riforma costituzionale del 2001 vengono indagate tenendo conto anche della stratificazione normativa rilevante per il settore in oggetto nonché dei limiti e delle interferenze materiali così come individuati dalla giurisprudenza costituzionale. Il risultato dell'analisi evidenzia uno spazio di competenza regionale assai più ridotto di quanto la lettera della Costituzione lascerebbe pensare

About FSD-FS
FSD-FS is an open database for multi-label few-shot audio classification containing 143 classes drawn from the FSD50K. It also inherits the AudioSet Ontology. FSD-FS follows the ratio 7:2:1 to split classes into base, validation, and evaluation sets, so there are 98 classes in the base set, 30 classes in the validation set, and 15 classes in the evaluation set (More details can be found in our paper).

Tissue architecture of the anterior pituitary showing the epithelial cell cords with hormonal cells and folliculo-stellate (FS) cells, the capillaries (C) with fenestrated endothelial cells (EC) and connective tissue (CT)

Journal Compilation © 2008 Blackwell Publishing Ltd</p> The cell cords are a cluster of endocrine cells surrounding an aggregate of FS cells that make a follicle (F). FS cells also make a meshwork between the hormonal cells, making junctions among each other (thick lines) and extending foot processes (f) ending on the basal membrane (BM) in the periphery of the cord. The cords are surrounded by BM, which may have extensions between some cells. A second BM surrounds the capillary vessels and between these two some connective tissue resides. Small and larger lacunae are present between hormonal cells. Paracrine substances may circulate from cell-to-cell but also could be released in these lacunae and reach more remote places. FS cells make gap junctions mostly among each other, but occasionally also with some hormonal cells. Hormonal cells can make interdigitations with FS cells (small arrows) to favour cell-to-cell communication. Adapted from Vila-Porcile ()
Adaptive pulse compression for transform-limited 15-fs high-energy pulse generation
Full text linkWe demonstrate the use of a deformable-mirror pulse shaper, combined with an evolutionary optimization algorithm, to correct high-order residual phase aberrations in a 1-mJ, 1-kHz, 15-fs laser amplifier. Frequency resolved optical gating measurements reveal that the output pulse duration of 15.2 fs is within our measurement error of the theoretical transform limit. This technique significantly reduces the pulse duration and the temporal prepulse energy of the pulse while increasing the peak intensity by 26%. It is demonstrated, for what is believed to be the first time, that the problem of pedestals in laser amplifiers can be addressed by spectral-domain correction
