Sort and beer: Everything you wanted to know about the sorting task but did not dare to ask

2011

author cannot archive publisher's version/PDF; International audience; In industries, the sensory characteristics of products are key points to control. The method commonly used to characterize and describe products is the conventional profile. This very efficient method requires a lot of time to train assessors and to teach them how to quantify the sensory characteristics of interest. Over the last few years, other faster and less restricting methods have been developed, such as free choice profile, flash profile, projective mapping or sorting tasks. Among these methods, the sorting task has recently become quite popular in sensory evaluation because of its simplicity: it only requires ass…

Physicochemical properties, sugar profile, and non-starch polysaccharides characterization of old wheat malt landraces

2021

Abstract Craft beers produced by small breweries are becoming increasingly popular worldwide due to their unique composition, taste, and flavour. Wheat malt is a traditional brewing raw material with great potential to improve beer properties such as mouthfeel, foam, haze, and flavour. In this study, the malting quality of eight wheat varieties (four common and four durum) was evaluated to explore the feasibility of producing 100 % wheat malt beer from old landraces. The physicochemical characteristics such as friability, Kolbach index, viscosity, and colour, of the wheat malts indicated a better degree of modification in the common wheat varieties when compared to that of the durum wheat v…

Non-parametric approaches to the impact of Holstein heifer growth from birth to insemination on their dairy performance at lactation one

2012

SUMMARYParametric approaches have been used widely to model animal growth and study the impact of growth profile on performance. Individual variation is often not considered in such approaches. However, non-parametric modelling allows this. Such an approach, based on spline functions, was used to study the importance of growth profiles from age 0 to 15 months (i.e. insemination) on milk yield and composition in primiparous cows. A dataset of 447 heifers was used for analysis of growth performance; 296 of them were also used to study impact on lactation. All of them originated from a French experimental herd and were born between 1986 and 2006. Clustering methods were also tested. Comparison…

Assessment of genetically modified sugar beet H7‐1 for renewal of authorisation under Regulation (EC) No 1829/2003 (application EFSA‐GMO‐RX‐006)

2017

Efsa Panel On Genetically Modified Organisms (gmo)Scientific opinionRequestor: European Commission (DG SANTE)Question number: EFSA-Q-2017-00026; Following the submission of application EFSA-GMO-RX-006 under Regulation (EC) No 1829/2003 fromKWS SAAT SE and Monsanto Company, the Panel on Genetically Modified Organisms of the EuropeanFood Safety Authority (GMO Panel) was asked to deliver a scientific risk assessment on the datasubmitted in the context of the renewal of authorisation application for the herbicide-tolerantgenetically modified sugar beet H7-1.

Toward a better understanding of in-field weed regulation by carabid beetles, and their functional characteristics, in European arable landscapes

2019

For future arable agriculture, there is a need for more sustainable methods to manage weeds that are less reliant on herbicides and maintain food production. Control of weeds by natural enemies is an agro-ecological alternative to reduce the use of herbicides. While strong evidence points to carabid beetles exerting a regulatory effect on certain weed species, it is difficult to predict whether a particular assemblage of carabid species or functional groups will drive the function of weed seed predation in field conditions. There are also uncertainties about which key local and landscape-scale factors affect the function of weed seed predation, and the functional characteristics of carabid …

Ingested soil is a major vector of organic contaminants from environment to free-ranged animals, particularly for grazing herbivores. Therefore, a better understanding of processes driving soil intake may provide new insights to limit animal exposure to contaminants and ensure safety of animal products. To maintain the supply service of livestock farming activities in contaminated areas, it is necessary to design adapted farming practices aiming at controlling the risk for human health. This study was conducted in the French West Indies, where chlordecone, an organochlorine insecticide previously used to protect banana plantation against the black weevil and banned since 1993, has polluted …

Studies of Tz= -3/2 nuclei of astrophysical interest

2011

This thesis presents a summary of experimental studies of -decaying Tz = 􀀀3=2 nuclei 23Al and 31Cl. The properties of these nuclei and the respective -decay daughters, 23Mg and 31S, have an in uence on the end products of ONe nova outbursts. The experiments were carried out at the IGISOL facility in the Accelerator laboratory of University of Jyväskylä and at the Cyclotron institute of Texas A&M University. The mass excess of 23Al was determined with Penning trap mass spectrometry by using the JYFLTRAP setup at IGISOL facility. The new mass excess is two orders of magnitude more precise than the previous value. A good agreement between theory and experimental values was found when applying…

Estimation of the committed radiation dose resulting from gamma radionuclides ingested with food

2014

The objective of the study was to estimate the value of the radiation dose absorbed in consequence of consumption of popular food products for individual age groups. Potatoes, corn and sugar beet were selected for the study. Edible parts of these plants were collected in experimental fields of the KWS Lochow Polska Sp. z o.o. seeding company in Kondratowice (Poland). On the basis of the obtained study results, it can be stated that in consequence of consumption of the selected food products, people may receive increased doses from both natural and artificial radioactive isotopes. The doses calculated for several age groups do not show any health hazards in consequence of consumption of the …

Gap perception in bumblebees

2018

ABSTRACT A number of insects fly over long distances below the natural canopy, where the physical environment is highly cluttered consisting of obstacles of varying shape, size and texture. While navigating within such environments, animals need to perceive and disambiguate environmental features that might obstruct their flight. The most elemental aspect of aerial navigation through such environments is gap identification and ‘passability’ evaluation. We used bumblebees to seek insights into the mechanisms used for gap identification when confronted with an obstacle in their flight path and behavioral compensations employed to assess gap properties. Initially, bumblebee foragers were train…

Isovector and isoscalar spin-multipole giant resonances in the parent and daughter nuclei of double-β-decay triplets

2022

The strength distributions, including giant resonances, of isovector and isoscalar spin-multipole transitions in the commonly studied double-β-decay triplets are computed in the framework of the quasiparticle random-phase approximation (QRPA) using the Bonn-A two-body interaction in no-core single-particle valence spaces. The studied nuclei include the double-β parent and daughter pairs (76Ge, 76Se), (82Se, 82Kr), (96Zr, 96Mo), (100Mo, 100Ru), (116Cd, 116Sn), (128Te, 128Xe), (130Te, 130Xe), and (136Xe, 136Ba). The studied transitions proceed from the ground states to the Jπ=0−,1−,2− (spin-dipole transitions) and Jπ=1+,2+,3+ (spin-quadrupole transitions) excited states in these nuclei. Compa…
