Suspension cultures were incubated in the presence and absence of gibberellic acid (GA(3)) in an attempt to define a new experimental system for study of the molecular action of gibberellins upon growth. Unlike many suspension cultures, an auxin-independent green clone from spinach (Spinacia oleracea L.) and an auxin-dependent line of "Paul's Scarlet" rose (Rosa sp.) were promoted in expansion ...

Natural dyes have become a viable alternative to expensive organic sensitizers because of their low cost of production, abundance in supply, and eco-friendliness. We evaluated 35 native plants containing anthocyanin pigments as potential sensitizers for DSSCs. Melastoma malabathricum (fruit pulp), Hibiscus rosa-sinensis (flower), and Codiaeum variegatum (leaves) showed the highest absorption pe...

BACKGROUND As an appropriate tool, membrane process is used for desalination of brackish water, in the production of drinking water. The present study aims to investigate desalination processes of brackish water of Qom Province in Iran. METHODS This study was carried out at the central laboratory of Water and Wastewater Company of the studied area. To this aim, membrane processes, including n...

Here we have characterized the putative Zn(II)2Cys6 transcription factor RosA from the filamentous fungus Aspergillus nidulans. The rosA gene encodes a protein of 713 aa, which shares 38% sequence similarity to Pro1 from Sordaria macrospora. In contrast to Pro1, which promotes the transition from protoperithecia to perithecia, RosA is a negative regulator of sexual development in A. nidulans. T...

In this work we present the first version of ROSA Analyser, a tool designed to get closer to a fully automatic process of analysing the behaviour of a system specified as a process of the Markovian Process Algebra ROSA. In this first development stage, ROSA Analyser is able to generate the Labelled Transition System, according to ROSA Operational Semantics. ROSA Analyser performance starts with...
