where H-H-C and H-D-C are weak bonds and make a negligible contribution, leads to a value of -2 kcal. Therefore, E5-E2=1 kcal compared with the experimental value of 1.0 kcal. The preexponential factor for this pair of isotopic reactions can be calculated from the difference in the entropies of activation. Using the same loose complex as above and applying the expression derived by Bigeleisens ...

McCrink (McCrink, Dehaene, & Dehaene-Lambertz (2007). Moving along the number line: Operational momentum in nonsymbolic arithmetic. Perception and Psychophysics, 69(8), 1324-1333) documented an "Operational Momentum" (OM) effect - overestimation of addition and underestimation of subtraction outcomes in non-symbolic (dot pattern) arithmetic. We investigated whether OM also occurs with Arabic nu...

ABSTRACT There is evidence that the star formation process linked to intricate net of filaments in molecular clouds, which may be also due gas compression from external triggers. We studied southern region Perseus NGC 1333 cloud, known heavily shaped by similar triggers, shed light on perturbed filament where Class 0 IRAS4 protostars lie. use new IRAM-NOEMA observations SiO and CH3OH, both trac...

Background: Cassava production faces threat from postharvest physiological deterioration (PPD). The PPD is usually observed within the first 72 hours of harvest. Therefore, extending shelf-life cassava root-tubers by few days could reduce appreciable financial losses. Objective: This study aimed to investigate effects sucrose and ascorbic acid on induction micro-tubers cultivars using an In-vit...
