La pointe Nord-est de la plaque arabique et plus précisément le Sultanat d’Oman s’avère être un territoire d’exception pour comprendre les questions géologiques géomorphologiques qui se posent aux scientifiques. Que ce soient problèmes tectonique des plaques, orogenèses (lithologie, structure, tectonique) ou morphologies surface (érosion fluviale, éolienne, littorale, karstogenèse, etc.) parcou...

The sex pheromone protoplast release-inducing protein (PR-IP) inducer and a sexual cell division-inducing pheromone-minus (SCD-IP-minus) that mediates the sexual reproduction of the heterothallic Closterium peracerosum-strigosum-littorale (C. psl) complex were investigated in this study. Recombinant PR-IP inducer produced by yeast cells was prepared and assayed for production of PR-IP and induc...

Sinensetin acid have the potential as antiviral agents. focus of this research is purple white-purple varieties. This study aimed to determine levels three secondary metabolites aristatus, one specific standardizations.
 Methods: standardization parameters be tested were compound by using thin-lay...
