étude d'un procédé de transformation des mono-di-, et oligo-et polysaccharides en acide lactique
LE TRAVAIL EST MENE POUR DEVELOPPER LA METHODE DE PRODUCTION DE L'ACIDE LACTIQUE PAR VOIE CHIMIQUE (PAR DEGRADATION DES MONOSACCHARIDES, DI-, ET POLYSACCHARIDES EN MILIEU BASIQUE). LE BUT DE CETTE RECHERCHE EST DE MINIMISER LE TEMPS DE PRODUCTION, L'ESPACE DE PRODUCTION ET AMELIORE LE RENDEMENT DE CONVERSION D'ACIDE LACTIQUE. L'ETUDE CINETIQUE DE LA TRANSFORMATION DES SUCRES EN ACIDE LACTIQUE A ETE REALISE EN MILIEU DOUCE. L'AMELIORATION DE LA CONVERSION DES SUCRES EST FAIT PAR L'UTILISATION D'UN MODELE DE TENDANCE STOECHIOMETRIE ET UN MODELE STATISTIQUE POUR ATTEINDRE LE RENDEMENT DE CONVERSION EN ACIDE LACTIQUE DE 80%. UN PROCEDE SEMI-CONTINU EST PROPOSE POUR LA CONVERSION DES SUCRES EN ACIDE LACTIQUE AVEC UN RENDEMENT MASSIQUE DE 87% A PARTIR DU FRUCTOSE. UN PROCEDE COMPACT BASE SUR UN CONTACTEUR GAZ/LIQUIDE A ETE REALISE POUR LA TRANSFORMATION ALCALINE DES SUCRES ET DES HEMICELLULOSES EN ACIDE LACTIQUE. LA CONVERSION DES MONOSACCHARIDES ET DISACCHARIDES DANS CES CONDITIONS ATTEINT AU RENDEMENT MAXIMALE DE 89% POUR LE FRUCTOSE. UN PLAN D'EXPERIENCE DU TYPE DOEHLERT EST UTILISE POUR ETUDIER LES EFFETS DE I) LA TEMPERATURE DU REACTEUR, ET II) LE TEMPS DE SEJOUR, SUR LA CONVERSION DES HEMICELLULOSES EN ACIDE LACTIQUE. LES RESULTATS MONTRENT QUE LA CONVERSION DES HEMICELLULOSES SONT POSSIBLES ET DES RENDEMENTS MASSIQUE D'ACIDE LACTIQUE DE 22% ET 37% SONT OBTENUS AUX CONDITIONS EXPERIMENTALES LES PLUS FAVORABLES D'APRES LE MODELE DEVELOPPE.

multidimensional scaling established that two of four metacognitive link weights
were significantly associated with (1) three of six measures of sorting
performance, and (2) one of two dimensions derived for the scaling solution of
pairwise similarity ratings.
The papers comprising this volume are selected from presentations made at the 2001 Conference of the British Association of Lecturers in English for Academic Purposes, which was held at the University of Strathclyde (in Glasgow, Scotland). The role of EAP (English for Academic Purposes) is increasingly important, as higher education institutions consider their linguistic support strategies (both for native and non-native speakers of English), and confront the potential of the world wide web as a scholarly and pedagogic resource. The articles collected consider EAP - as an international profession - from a number of vital and relevant perspectives including practical pedagogy, research, and the impact of new technology.
With this in mind the suggestion that a single academic writing course, for
example, could be expected to provide effective help for students across a wide
range of subject areas is perhaps suspect. Ron White considers the ...
Commenting in the main on students having a Confucian cultural heritage, she
advocates the explicit teaching of metacognitive strategies which encourage learners both to discern how academic text is structured and to make use of these
in their own writing.
This step-by-step plan contains 150 teacher-tested activities in social skills for all students in grades 4-12. The emphasis is on helping students to develop self-control, evaluation techniques, the ability to make better choices, & foresightedness. Their problem-solving skills, observation skills, & communication skills are addressed. Students learn how to act responsibly, set goals, change their own behavior, become more sensitive to the needs of others & more willing to change. Out-of-school practice activities, easy-to-follow lesson plans, & clear, concise directions on how to use them are included. Ready-to-copy activities & worksheets, plus a guide that tells you how to adapt for 4- to 18-week sessions are also provided.
