Selection of probiotic strains and improving the survival and functionality of an academic strain, Bifidobacterium bifidum, by changing the redox pot…
2012
The aim of this work was to select rationally a probiotic strain by setting up a screening method as well as study and understand the impact of the redox potential (Eh) and gas bubbling on the survival of Bifidobacterium bifidum in a fermented dairy product. In a first time, we have developed selection techniques of probiotic bacteria on the criteria of viability / vitality (flow cytometry analysis) and on the criteria of functionality (antioxidant). We were able to select strains of industrial interest as well as an academic strain, Bifidobacterium bifidum.Secondly, we have studied effect of modifying redox potential by gas bubbling on the survival of B. bifidum in a fermented dairy produc…
Using cross-modal interactions to counterbalance salt reduction in solid foods
2011
International audience; We investigated odour-induced saltiness enhancement (OISE) in a solid model cheese with the aim of evaluating the influence of cross-modal interactions (odour-texture-taste) on saltiness perception and assessing the efficacy of using OISE to counterbalance salt reduction. Four model cheeses, varying in texture, were flavoured with three commercial tasteless aromas (comte cheese, sardine and carrot) differently associated with salty and cheesy food products. Twenty-seven consumers evaluated taste intensity, aroma intensity and its congruence with the product flavour, and the overall pleasantness of 12 flavoured and four unflavoured samples. The comparison of the perce…
Potential of crop mixtures to reduce pesticide use in France. A data analysis
2022
Over the last 50 years, agricultural intensification has led to simplified agricultural systemshighly dependent on fertilisers and pesticides, causing biodiversity loss, changes in the balanceof nutrients, water and soil contamination. The total amount of pesticides applied each yearin France makes it the main consumer of plant protection products in Europe, and arable cropsare currently the most pesticide-consuming production systems. Reducing pesticide use inarable crops is thus a major challenge. There is now evidence that crop diversification in time,with more diversified rotations, and in space, through crop mixtures, can help restoreecosystem services and represent a potential key lev…
Performances of neural networks for deriving LAI estimates from existing CYCLOPES and MODIS products
2008
International audience; This paper evaluates the performances of a neural network approach to estimate LAI from CYCLOPES and MODIS nadir normalized reflectance and LAI products. A data base was generated from these products over the BELMANIP sites during the 2001-2003 period. Data were aggregated at 3 km x 3 km, resampled at 1/16 days temporal frequency and filtered to reject outliers. VEGETATION and MODIS reflectances show very consistent values in the red, near infrared and short wave infrared bands. Neural networks were trained over part of this data base for each of the 6 MODIS biome classes to retrieve both MODIS and CYCLOPES LAI products. Results show very good performances of neural …
Ibuprofen degradation using a Co-doped carbon matrix derived from peat as a peroxymonosulphate activator
2021
The wider presence of pharmaceuticals and personal care products in nature is a major cause for concern in society. Among pharmaceuticals, the anti-inflammatory drug ibuprofen has commonly been found in aquatic and soil environments. We produced a Co-doped carbon matrix (Co-P 850) through the carbonization of Co2+ saturated peat and used it as a peroxymonosulphate activator to aid ibuprofen degradation. The properties of Co-P 850 were analysed using field emission scanning electron microscopy, energy filtered transmission electron microscopy and X-ray photoelectron spectroscopy. The characterization results showed that Co/Fe oxides were generated and tightly embedded into the carbon matrix …

ISSUES CONCERNING THE TYPOLOGY OF RURAL TOURISTIC PENSIONS FORM MARGINIMEA SIBIULUI, SIBIU COUNTY, ROMANIA
2014
The study was conducted in May-June 2013, in two places in the tourist area called "Mărginimea Sibiului", Sibiu, Romania. The research instrument used was a questionnaire comprising 25 questions and was sent to the owners / managers of pensions (18 people) by 9 people from rural places Sibiel and 9 people from Gura Râului. According to data from Sibiu County Tourism Association, in Sibiel there are recorded 40 tourist structures, and in Gura Râului, 22. Data from the field were processed, systematized and interpreted. The overall objectives were: establishing typology of tourist structures, knowing the comfort of pensions, the average capacity of accommodation, the average length of stay. S…
Airlines Customer Segmentation in the Hyper-Competition Era
2019
As the airline industry reaches its maturity, so do the passengers who are looking for more sophistication in terms of the products and services they buy or expect. Offering a large array of services to customers with different expectations who await customization along their journey has become more challenging for airlines all over the world. Coping with changes in a volatile environment means that airlines need to redefine their customer segmentation, evolving from a social-demographic to a more complicated behavioral approach which encompasses the whole traveling experience and the way airlines deliver at every touching point.
REMOVAL OF BITTER COMPOUNDS FROM CITRUS BYPRODUCTS
2013
Bitter compounds such as limonoids, which consist of oxygenated triterpenoid compounds, are present in citrus fruits. Removal of limonoids from citrus fruits is of considerable importance for the citrus industry. Researchers have removed limonoids from citrus fruits and citrus byproducts using organic solvents. The objective of this study was to use a simpler method to remove limonoids from citrus byproducts.
Fast blue B functionalized silica-polymer composite to evaluate 3,5-dihy-droxyhydrocinnamic acid as biomarker of gluten intake
2021
Celiac disease is an immune-mediated systemic disorder elicited by gluten and related prolamines in genetically susceptible individuals. The current treatment is a strict and lifelong gluten-free diet. However, compliance with the gluten-free diet is not always adequate and many food products contain low concentrations of gluten. The determination of dietary transgressions is a challenge for patients, physicians and dietitians. Alkylresorcinols (AR) have been proposed as sensitive and specific biomarkers of gluten consumption. In this work silica-polymer composites doped with fast blue B reagent (FB) have been used to estimate alkylresorcinols in biological samples. The proposed colorimetri…
