No full textHigh quality wine requires high quality grape. High quality grape means good aromatic properties and texture, excellent phenols panorama, and salubrity. Ozone is known as a great sanitizing agent but little is known on its effect on grape metabolism. Grape bunches of 'Sauvignon Blanc' (Vitis vinifera L.) were hand harvested at the end of day in Castello de "La Sala" winery, placed in perforated boxes in one single layer and then stacked in a cold room at 10°C and 70% RH (relative humidity). Ozone treatment (1.5 g h-1) started immediately and bunches were sampled before and after treatment which lasted 4, 8, and 16 h. The control sample consisted in grape bunch treated in similar way, placed in another cold room without ozone treatment. Total phenols on dry weight (d.w.) basis increased of 10% after 8 and 16 h treatment compared to the control sample. Hydroxycinnamic acids increased 50-100% in ozone-treated sample. Even total carotenoids raised in ozonetreated sample after 16 h. Glycosilated volatiles organic compounds (VOCs) increased in ozone-treated samples while decreased in untreated one; in contrast the free VOCs, which means the perceptible aroma compounds, were higher in untreated grape. This is an important result because the grape for vinification must have many glycosilated VOCs before fermentation which are released during the process by yeasts
Ozone fumigation for safety and quality of wine grapes in postharvest dehydration.
No full textThis paper proposes postharvest ozone fumigation (as a method) to control microorganisms and evaluate the effect on polyphenols, anthocyanins, carotenoids and cell wall enzymes during the grape dehydration for wine production. Pignola grapes were ozone-treated (1.5 g/h) for 18 h (A = shock treatment), then dehydrated or ozone-treated (1.5 g/h) for 18 h and at 0.5 g/h for 4 h each day (B = long-term treatment) during dehydration. Treatment and dehydration were performed at 10 degrees C. No significant difference was found for total carotenoid, total phenolic and total anthocyanin contents after 18 h of O-3 treatment. A significant decrease in phenolic and anthocyanin contents occurred during treatment B. Also carotenoids were affected by B ozone treatment. Pectin methylesterase (PME) and polygalacturonase (PG) activities were higher in A-treated grapes during dehydration. Finally, ozone reduced fungi and yeasts by 50%. Shock ozone fumigation (A treatment) before dehydration can be used to reduce the microbial count during dehydration without affecting polyphenol and carotenoid contents
Postharvest dehydration of wine white grapes to increase genistein, daidzein and the main carotenoids
No full textWine white grape bunches of the Grechetto variety were dehydrated at 10, 20 and 30 C, RH 45% and
forced air ventilation of 1.5 m/s. Chemical and metabolic changes due to the effect of dehydration were
studied at various stages of weight loss: 10%, 20%, 30% and 40%. Berry colour at 10 and 20 C tended to
become greener with dehydration but at 30 C, at the final sampling, the colour darkened. Acidity
decreased in all samples, while sugars increased. Total phenol content increased at 10 C until 30% weight
loss was reached and then declined, while at 20 and 30 C the concentration decreased immediately. The
contents of lutein and b-carotene (respectively 68 and 58 mg/kg d.w.), representing the 80% of total
carotenoids, did not change significantly until the 30% of weight loss, when at 30 C the value increased
above all for lutein while at 10 and 20 C, the contents decreased significantly. Daidzein, at 10 C, rose
significantly from about 150 lg/kg d.w. to 1434 lg/kg d.w. at 20% weight loss and then declined; at
the same weight loss percentage, the genistein concentration began to increase. At 20 C both isoflavones
rose until the end of the experiment, reaching values similar to the sample at 10 C. A temperature of
30 C was deleterious to grape isoflavones. A discussion on the changes in isoflavones related to temperature
and time is repor
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

Final height outcome in both untreated and testosterone-treated boys with constitutional delay of growth and puberty
No full textThe present retrospective study is based on a historical follow-up of 49 boys with constitutional delay of growth and puberty (CDGP) who went into puberty spontaneously (27 cases) or induced by depotestosterone treatment, 50 mg/month for 6 months (22 cases), At the time of puberty the two groups of boys were similar in bone age, height deficiency, target height (TH) and had similar predicted final heights (FH). Their FH was measured and compared with TH calculated from measured parents' heights. FH did not significantly differ between the untreated boys and those treated, In the two groups of patients FH was similar and corresponded to both TH and height predicted at puberty onset, This study confirms that most boys with CDGP spontaneously attain a FH within the target range (24/27 cases), A short-term and low dose course of depotestosterone can be used without adverse effects on FH, The Bayley-Pinneau method can be generally considered accurate for predicting FH in CDGP, although significant discrepancies between FH and predicted height have been recorded in a fair number of both untreated and treated boys
Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
John F. Kennedy telegram to Roosevelt
No full textJersey Homesteads (later the Borough of Roosevelt) was established in the 1930s as an agro-industrial cooperative community. It was established specifically for urban Jewish garment workers, many of whom had emigrated from Europe. President John F. Kennedy sent a telegram to the citizens of Roosevelt, New Jersey, apologizing for not being able to attend the memorial dedication in honor of former President Franklin Delano Roosevelt. (Jersey Homesteads became Roosevelt in 1945 in honor of the president.) President Kennedy expressed his gratitude to the people of Roosevelt for constructing the memorial, and commented that it will serve as a constant reminder of Roosevelt's good works
