The non-energetic valorisation of renewable resources using efficient and eco-friendly methodologies is the central axis of the "green chemistry" concept. In particular, the chemical and chemo-enzymatical transformations of carbohydrates arising from the hydrolysis of non-edible vegetal feedstock (i.e., lignocellulosic biomass) are a widely explored thematic for the production of new high-added value materials, synthons, and platform chemicals. Since the seminal works of Gedye and Giguere in 1986, the use of microwaves as a non-conventional heating source has gained large attention in organic chemistry. Due to commonly observed acceleration in reactions rates and improved selectvities and yields, microwave heating has progressively emerged as a green chemistry technology. Minimizing both energy consumption (via the reduction of temperature and reaction times) and wastes (by improvement of selectivity), microwaves has enjoyed significant adoption by the research community. This chapter describes the use of microwave processes to mediate key reactions in the field of carbohydrates chemistry. Some examples of typical carbohydrates reactions (glycosylations, hydroxyl groups’ protection, etc.) under microwave conditions are displayed and highlight the benefits of this microwave approach in terms of yields, atom efficiency, environmental factor, and carbon efficiency.

‘Green note’ aldehydes were successfully reduced into their corresponding alcohol by commercial yeast alcohol dehydrogenase. Among different yeasts tested for their ability to convert (Z)-3-hexenal into (Z)-3-hexenol, Pichia anomala gave the best results. Conversion yields higher than 90% were also obtained by directly conducting the reaction in the medium where (Z)-3-hexenal is produced by the action of lipoxygenase and hydroperoxide lyase on <br />linolenic acid.

Soils in Belgium were mapped between 1947 and 1991 and published at a 1:20000 scale. These maps are used in land consolidation projects and for assessing soils’ vulnerability to erosion and pollution. Integration of land-use and environmental policies within the European Union however requires a harmonization of different national soil classification systems. With the World Reference Base for Soil Resources (WRB) as common classification system within the Union, the authorities of Flanders and Wallonia commissioned a study to elaborate a methodology for converting the Belgian soil legend into WRB. The Belgian legend is based on field properties such as texture, drainage status and profile development. The WRB classification is based on diagnostic features defined by morphological, physical and chemical properties. A key and software programme have been developed to convert the Belgian units into WRB units. However, as many Belgian units could not unequivocally be translated into WRB units, additional guidelines had to be derived based on soil survey data classified according to WRB. The data show that principles of the legend shifted over time or were interpreted differently to take regional specificities into account. To overcome resulting ambiguities it is proposed to establish a database of reference soil profiles. Whereas, overall WRB is satisfactory for classifying soils at national level, the experience also shows that some WRB concepts may benefit from revisions to facilitate its correlation with national soil survey data.

Within the European Union, there is a general interest to prepare joint soil maps at a 1:250000 scale in order to harmonise agricultural and environmental policies. The World Reference Base for Soil Resources (WRB) has been adopted as the common soil classification system within the EU. As soil surveys in most member states were conducted independently, the challenge is now to convert the national legends into a common WRB legend. Based on our experiences from converting the legend of the Soil Map of Belgium to WRB, we discuss the strengths and constraints of using WRB for both large scale (1:50000) and small scale (1:250000) maps. By using WRB Reference Soil Groups with one or two main qualifiers, the principal soil information of the original 1:20000 scale Soil Map of Belgium can be represented. Inevitably the conversion to WRB leads to some loss of information as details on soil texture, drainage and substratum get generalised into broader categories in WRB. This generalisation however can be neatly presented on 1:50000 scale maps. Being less complex than the original maps, these maps have the advantage to provide better insights into the regional soil geography. Moreover, as they are built on international classification concepts, the historical soil maps are made accessible to a wider audience. The conversion into WRB units also allowed for a straightforward generalisation and production of small scale maps (1:250000) which should be suitable for producing a soil map at European level.

Summary A prospective and descriptive study including 148 children (age: 5-71 months) presenting with febrile seizures (FS) at two Primary Health Care centres in Kinshasa, was conducted over a period of 3 months. Type of seizure (genaralized or focal), its duration, and its characteristic (recurrent or not), were documented, to assess the severity of the disorder. The Psychomotor Development (PMD) of each patient was evaluated, using the Gensini and Gavito scale and then the Psychomotor Development Quotient (PDQ) calculated, according to the motor, communication, and social domains. Main results were: a reduction in PDQ (6.7%), motor delay (5%), communication delay (3.4%), and social delay (2.7%), based on this scale. No significant link was found between global PDQ reduction and markers of FS severity. However, recurrent seizures seemed strongly associated to delayed motor development (p=0.02 [OR=1.096, CI: 1.060-1.128]). These findings suggest that the motor domain could be more affected in children presenting FS, especially those with recurrent seizures. This link needs to be clearly established through larger case-control studies. [less ▲]

L’acquisition de la représentation du temps nous donne, avec le développement du langage, accès à la narrativité. Ces histoires que nous racontons aux enfants leur permettent d’accéder au monde de la signification. Peu à peu l’enfant s’approprie sa propre histoire en même temps qu’il constitue son identité. Le concept de self narrative (Denett, 1991), matérialisé dans le discours par l’utilisation des pronoms personnels, est un premier produit de cette évolution. Il est donc intéressant de connaître la manière dont se construit ce récit qui deviendra autobiographique à l’adolescence. [less ▲]

À partir de l’enregistrement de discours spontanés d’enfants âgés de 3 à 8 ans dans trois conditions (psychologue, groupe, parents), l’objectif de cette recherche sera d’appréhender le développement du rapport que l’enfant entretient avec lui-même et les autres en observant la distribution et les utilisations particulières des formes personnelles chez l’enfant. Pour qualifier ces emplois, nous examinerons le détail des cooccurrents des pronoms pour chaque catégorie considérée. La situation de groupe s’étant avérée particulièrement concluante, nous lui consacrerons la dernière partie de nos explorations en nous concentrant sur l’asymétrie cooccurrentielle du couple moi-je dans la continuité de nos travaux autour de l’asymétrie de la relation coocurrentielle (Luong et al. 2010) en insistant sur leurs résonances dans le développement de l’identité chez l’enfant.
