Endogenous concentrations of indole-3-acetic acid (IAA) and cytokinins were compared to the tendency for plagiogravitropjc growth in rooted stein cuttings of Douglas-fir. A chromatographic method was developed for
the purification and quantitation of trace levels of IAA. Two elutions with reverse-phase high performance liquid
chromatography (HPLC) using a fluorescence detector...
Eola rasp leaf of cherry was first described by Milbrath and
Reynolds in Oregon in 1961. Dr. Cadman of the Scottish Horticultural
Research Institute suggested that this disease was incited by a strain
of tomato ringspot virus (TomRSV), but since then controversial results
with some isolates of EoIa rasp leaf...
A new group of lead free piezoelectric perovskite solid solutions, (1-x)Bi(B'B")O₃-xABO₃, were obtained via solid-state processing techniques. The solubility of unstable perovskite Bi(B'B")O₃ compounds into stable perovskite compounds was found to be related to the tolerance factor of the ABO₃ perovskite endmembers. The morphotropic phase boundary (MBP) in perovskite solid...
Work on individually constructed devices has demonstrated that nanowires (NWs) offer great promise for applications such as sensing and optoelectronics. Despite this work, reliable large scale alignment and integration of these individual nanostructures into a lithographically defined process remains a challenge.
Dielectrophoresis (DEP) is a promising alignment method in which...
With the expansion of transport, increasing car ownership, rapid increase in outbound travel and new interests in nature based eco-tourism, and the adoption of 5 work days, marine eco-tourism is expected to have a very promising future and need more detailed preparation and planning. While marine eco-tourism occupies 30% of...
La réalisation d'une zone d'éco-aménagement située entre Bouskour et Cala Iris se justifie par le fait que les communautés de pêcheurs et autres communautés vivant des ressources maritimes subissent un profond traumatisme car les stocks biologiques de la zone sont de moins en moins capables de les faire vivre. L'objectif...
The role of nanotopographical extracellular matrix (ECM) cues in vascular endothelial cell (EC) organization and function is not well-understood, despite the composition of nano- to microscale fibrillar ECMs within blood vessels. Instead, the predominant modulator of EC organization and function is traditionally thought to be hemodynamic shear stress, in which...
