The criterion for con uence using decreasing diagrams is a generalization of several well-known con uence criteria in abstract rewriting, such as the strong con uence lemma. We give a new proof of the decreasing diagram theorem based on a geometric study of in nite reduction diagrams, arising from unsuccessful attempts to obtain a con uent diagram by tiling with elementary diagrams. 2000 Mathem...

In recent years in tegrated processes have attracted considerable attention in both academic research and industrial applications. The integration, for instance of reaction and separation, reduces the degrees of freedom and requires tigh t con trol to operate the processes at optimal conditions. F rom the available number of measurements and input variables, a con trol structure has to be iden ...

Exposure of CHO-K1 cells in vitro to dibutyryl adenosine cyclic 3',5'-monophosphate (DBcAMP) plus testololactone produces a rapid, reversible antagonism of ligand-induced collection of initially dispersed concanavalin A (Con A) binding sites into a caplike mass. Morphologically, as Con A capping occurs, the cells become less spread and then round completely. With prolonged Con A exposure, cells...

A con guration is weakly ag transitive if its group of automor phisms acts intransitively on ags but the group of all automorphisms and anti automorphisms acts transitively on ags It is shown that weakly ag transitive con gurations are in one to one correspondence with bipartite  arc transitive graphs of girth not less than Sev eral in nite families of weakly ag transitive con gurations are gi...

Resumen Discusión y revisión de la bibliografía a partir de un caso de un varón joven con síndrome de Down (SD) y trombosis venosa cerebral (TVC). Caso clínico. Varón de 27 años que comienza con cefalea, vómitos y hemiparesia izquierda. Tras encontrarse hallazgos en la neuroimagen compatibles con trombosis venosa cerebral, se inició tratamiento anticoagulante, con una evolución clínica favorabl...

UNLABELLED We recently reported that the greatest distinguishing feature between eccentric (ECC) and concentric (CON) muscle loading lays in architectural adaptations: ECC favors increases in fascicle length (Lf), associated with distal vastus lateralis muscle (VL) hypertrophy, and CON increases in pennation angle (PA). Here, we explored the interactions between structural and morphological rem...

The binding of concanavalin A (con A) to intact and detergent-solubilized fractions of rat liver mitochondria has been studied quantitatively using a turbidimetric agglutination assay and by a radioactive binding procedure employing [acefyl-3H]con A. The reaction appears to involve oligosaccharide residues associated with glycoproteins of the mitochondrion since glycosides such as methyl-c-u-D-...

Dairy cows are extremely inefficient at converting dietary nitrogen (N) to productive N. Approximately 25-30% of dietary N is used for milk protein while the remaining N is lost to the environment. According to National Research Council (NRC, 2001) recommendations, dairy cow rations are formulated in terms of metabolizable protein (MP) which often causes many amino acids (AA) to be fed in exces...

The distribution of concanavalin A (Con A) surface receptors and cytoplasmic actin in the same cell was studied in monolayer cultures of 2 odontogenic epithelial cells of different developmental age and in ecto-mesenchymal cells derived from the same tooth germ. Con A receptors were demonstrated by fluorescein-isothiocyanate-labelled Con A (FITC-Con A) and cytoplasmic actin by a specific anti-a...
