Since late 2000, we have acquired partial pressure of CO2 (pCO2) data underway with an equilibrator coupled to an infra-red gas analyser on all the cruises carried out on RV Belgica. Here, we discuss the decadal changes of pCO2 during winter-time in the Southern North Sea. The trends are faster than those reported in open oceanic waters, although strongly modulated by inter-annual variability that seems to be related to the North Atlantic Oscillation. [less ▲]

Major improvements have been made in mRNA quantification and internal standard selection over the last decade. Our aim in this paper is to present the main developments that are of interest for practical laboratory work, contrasting the situation as it is now with the one of ten years ago, and presenting some excellent examples of what can be done today. Specifically, we will mainly discuss Real-Time RT-PCR major improvements that have been performed in the following areas: the most commonly used quantification techniques, the mathematical and software tools created to help researchers in their work on internal standard selection, the availability of detection chemistries and technical information and of commercial tools and services. In addition to mRNA quantification, we will also discuss some aspects of non-coding RNA and protein quantification. In addition to technical improvements, the development of international cooperation and the creation of technical databases are likely to represent a major tool for the future in the standardization of gene expression quantification.

The past decade is characterized by major changes in the Information Technology (IT) environment in agriculture - e.g. from batch processing of management data at service centers to adoption of multiple, on-farm, IT installations. An 11 country survey identified nonstructured and variable adoption patterns with a wide range of IT specifics. Software development facilitated these changes. A time-series software-installation count provided a usefull indicator of which, how many, how fast and when software were adopted. Study of Internet implementation for agricultural extension provided additional insight and explanation of IT adoption processes. [less ▲]

Yarrowia lipolytica converts methyl ricinoleate to γ-decalactone, a high-value fruity aroma compound. The highest amount of 3-hydroxy-γ- decalactone produced by the yeast (263 mg∈l-1) occurred by increasing the k L a up to 120 h-1 at atmospheric pressure; above it, its concentration decreased, suggesting a predominance of the activity of 3-hydroxyacyl-CoA dehydrogenase. Cultures were grown under high-pressure, i.e., under increased O2 solubility, but, although growth was accelerated, γ-decalactone production decreased. However, by applying 0.5 MPa during growth and biotransformation gave increased concentrations of dec-2-en-4-olide and dec-3-en-4-olide (70 mg∈l -1). © Springer 2005. [less ▲]

Chargée d’un cours de statistique descriptive en 1ère année de bachelier en ingénieur de gestion à l’Université de Liège, nous avons voulu mettre en place une méthode d’enseignement centrée sur l’activité cognitive des apprenants (Henry – Leclercq [2]) et s’inscrivant dans une logique de développement de compétences transversales et disciplinaires. Les dispositions prises pour l’implémentation de ce dispositif nous ont conduit à identifier certaines difficultés relatives à l’apprentissage des notions concernées et dont nous ne soupçonnions pas la présence. Lors de l’exposé, nous relaterons principalement trois expériences réalisées en classe et qui sont à la source de nos constatations. La première activité, qui s’est déroulée lors du tout premier cours, était consacrée à des pré-requis supposés, soit les notions de pourcentage et de taux de variation. Cette séance consistait en un Questionnaire à Choix Multiples projeté à l’écran et pour lequel les étudiants disposaient de Boîtiers de Vote Electronique (Gilles et al. [1]). Ces BVE leur permettaient de répondre aux questions en appuyant sur le bouton correspondant à la solution choisie, les statistiques des solutions données par l’ensemble des étudiants s’affichant à l’écran dès la clôture des votes. La deuxième activité a consisté en la rédaction, par groupes d’étudiants, de démonstrations non encore exposées. Les productions des élèves ont été reprises et corrigées par l’enseignant. Nous décrirons quelque peu ce que ces travaux nous ont appris sur les représentations de nos étudiants. Enfin, nous avons eu l’occasion de mettre en place une activité de débat scientifique au sens de Marc Legrand (Legrand [3]) à propos de la définition de l’écart absolu moyen. Nous verrons comment cette activité s’est déroulée et comment une définition correcte a pu émerger des débats entre étudiants. Dans tout l’exposé, nous insisterons sur le décalage existant entre le discours de l’enseignant et les représentations mentales des étudiants ainsi que sur la nécessité de mettre à jour des conceptions qui peuvent nuire à la construction de savoirs que nous jugeons parfois élémentaires à l’université.

The study of the organ of Corti is essential to assess the impact of underwater noise on cetaceans. While classical histology techniques (including EDTA decalcification) have been previously considered, the process is time consuming. Independently from the histological technique, one of the challenging steps after extraction and fixation of the samples is to decalcify the bone envelope to access the cochlea without damaging the soft tissues. Here, we propose to use a fast commercial decalcifier (RDO (R)). 93 ears from 11 different odontocetes species stranded in the Mediterranean, Spanish North Atlantic and North Sea were used to precisely determine the decalcification time. Depending on the tympanic-periotic volume of the species, the decalcification time ranged from several hours to a few days, allowing a subsequently faster observation of the cochlear structures through routine microscope techniques.

The difficulty associated with an accurate determination of transition rates for forbidden lines in lowly ionized heavy elements is illustrated in the case of Nd II. We have investigated the radiative decay of the low-lying metastable levels in Nd+ including the two levels 4f(4)(I-5) 5d K-6(11/2) and 4f(4)(I-5) 5d I-6(13/2). In these two particular cases, using di. erent theoretical approaches, we. nd that the decay is dominated by the M1 channels but that the E2 contributions are of the same order of magnitude. These levels have also been studied experimentally by lifetime measurements with the heavy ion storage ring CRYRING of Stockholm University. The difficulties encountered when performing such experiments are underlined and discussed. [less ▲]
