Visual Search Performance Depending on Target-Distractor Difference on Volumetric Display and Flat Panel Display
2019
The search items were demonstrated on the volumetric display and flat panel display. In contrast to the correct response rate, the search time and number of interactions were considerably affected by the type of visualization.
Spectrophotometric determination of vitamin C using the copper(II)-nioxime-ascorbic acid system following stabilization in a propylene glycol medium
1989
Abstract A spectrophotometric method for the determination of Vitamin C is proposed. The procedure is based on formation and stabilization of the ternary complex Cu(II)-nioxime-ascorbic acid in 80% ( v v ) propylene glycol-water medium. The method has a high degree of tolerance for the determination of ascorbic acid in the presence of other active substances or excipients likely to be present along with vitamin C in pharmaceutical formulations. The suggested method has proved to be rapid and precise and has been successfully applied to different commercial pharmaceutical preparations of vitamin C. Precision, measured on the relative standard deviation, did not exceed 0.73%.
Crystalloid lysozyme inclusions in Paneth cells of vitamin A-deficient rats.
1990
The effect of vitamin A-deficiency on jejunal Paneth cells in rats was investigated. Crystalloid particles were observed in secretion granules of Paneth cells from 6 out of 8 rats with vitamin A-deficiency. The particles were similar to those found in Paneth cells under other experimental conditions. Using an immuno-electron-microscopic technique we demonstrated a clear lysozyme immunoreactivity of these particles. In 2 vitamin A-deficient rats tubular structures have been detected in addition to the crystalloid particles. Crystalloid particles or tubular structures were not detectable in a control group of 8 vitamin A-supplemented rats. The morphological alterations of Paneth cells may be …
Sistema automatico di protezione e di sicurezza per sistemi fotovoltaici.
2016
Sistema automatico di protezione e di sicurezza per sistemi fotovoltaici. The aim of the invention is to define a safety device for workers and/or operators in photovoltaic systems (PV) both during interventions of normal use (maintenance) and during emergency condition (fire, etc.).Thus, the permanence of continuous voltage along the stretch-line included between the inverter and the panel is still a problem that has not found solution. The scientific-technical objectives of the invention can be considered in the context of the evolving technology of PV system providing great security of the system itself. The system consists of a device, which prevent irradiation of the solar rays from th…
Italian red wine in the Japanese market: a hedonic price analysis
2017
This study applies the hedonic pricing model to examine important objective attributes appearing on the label of Italian wines influencing average customer wine prices in Japan. Data on 829 red Italian wines sold in the Japanese market were collected through the wine searcher dataset, and the information included on the wine labels, useful for assisting in the selection and appreciation of wines, has been included. A log-linear model was esteemed and the proposed hedonic equation accounted for 43.5% of the variation in wine prices. The results indicate that international grape varieties, alcohol content and the year of production explain most of the price difference. On the other hand, the …
Stress Responses of Oenococcus oeni
2011
Oenococcus oeni is an alcohol-tolerant, acidophilic lactic acid bacterium responsible for malolactic fermention in wine. The stress responses of O. oeni have been studied at both the molecular and physiological levels. Genes encoding stress proteins mainly belong to the CtsR regulon. Other regulation mechanisms seem to coexist in O. oeni and may correspond to posttranscriptional regulation. Maintenance of the cell membrane integrity under stress conditions seems to be a prerequisite for survival in wine. The active cell response to protect membrane function under stress conditions requires changes in fatty acid composition and involves stress proteins. Various solute transporters and energy…
Experiments of Reduced Working Hours in Finnish Municipalities
1999
This article examines experiments with shorter working hours in Finnish municipalities between 1996 and 1998. The article focuses on the effects of different working time experiments on employees (work ability), on working units (quality of services) and substitutes recruited during the experiments. The results indicate that shorter working hours reduce job exhaustion, with respect to both 6‐hour shifts and other forms of reduced hours. The participants reported positive changes the quality and availability of services, especially in the case of 6‐hour shifts. In addition, during the experiment, new employees (substitutes) reported improved chances to obtain work in the future; after the ex…
Structural characterization of 2,2-di-n-butyl-4-methyl-1,3,2-dioxastannolane isolated from supercritical CO2 conditions
2009
The title compound has been isolated as single crystals from the synthesis of propylene carbonate from racemic 1,2-propanediol and carbon dioxide using n-Bu2SnO as a catalyst precursor. The X-ray crystallographic structure analysis revealed the self-assembly of di-n-butyltin(IV) 1,2-propanediolate units, linked together through long-distance Sn-O interactions leading to a one-dimensional polymeric architecture organized in a syndiotactic arrangement. The coordination geometry around the tin atoms can be described as an unusual faced-capped trigonal bipyramidal environment.
Combining Olfactory and Gustatory Clues in the Judgment of Aging Potential of Red Wine by Wine Professionals
2010
International audience; The study was aimed at determining the relative importance of olfactory and gustatory information for the vin de garde concept, which refers to wine that is intended for aging. First, the study investigated how olfactory information contributed to the assessment of the aging potential of young wine. Burgundy wine professionals categorized 26 red wines (vintage 2005) according to their aging potential in two experimental conditions: orthonasal evaluation and overall evaluation. Second, the aromatic notes associated with wines perceived with an aging potential were examined. A trained descriptive panel described the odor of the 26 red wines to determine whether the win…
Le nombre de sujets dans les panels d'analyse sensorielle : une approche base de données
2012
The costs associated with sensory evaluation increase with the number of panelists to be enrolled. Classical power computation can be used to derive the minimal number of subjects of a sensory panel in order to control both type I (α risk) and type II (β risk) errors. However, this power computation requires estimates of the size of the product effect to be sought and of the residual variability of the ANOVA model used. Generally, both product effect size and residual variability are difficult to estimate a priori by the sensory analyst. This work offers estimations of these two parameters thanks to the analysis of hundreds descriptive andhedonic studies collected respectively in two databa…
