Modern business process modeling languages such as BPMN or EPC provide users with more constructs to represent real world situations than their predecessors such as IDEF or Petri Nets. But this apparent increase in expressiveness is accompanied by an increase in language complexity. In practice many organizations choose to only use a subset of the available modeling constructs. Using a wellesta...

The Arabidopsis thaliana vacuolar Na+/H+ antiporter AtNHX1 is a salt tolerance determinant. Predicted amino acid sequence similarity, protein topology and the presence of functional domains conserved in AtNHX1 and prototypical mammalian NHE Na+/H+ exchangers led to the identification of five additional AtNHX genes (AtNHX2-6). The AtNHX1 and AtNHX2 mRNAs are the most prevalent transcripts among ...

The Arabidopsis SOS2 family of twenty-six protein kinases (CIPKs), their interacting activators, the SOS3 family of ten calcium-binding proteins (CBLs) and protein phosphatases type 2C (PP2C), function together in decoding calcium signals elicited by different environmental stimuli. Biochemical data suggest that stable CBL-CIPK or CIPK-PP2C complexes may be regulating the activity of various su...

Owing to their sessile nature, plants are easily affected by various extenal factors. Among those, drought and salinity considered as the most common stresses, which often pose a threat plant growth development. Major effects of interconnected drive similar series molecular changes in plants. These alterations response stress under regulation signaling pathways, including engangement evolutiona...

it is difficult to disagree with the general argument that successful health reform requires a significant degree of policy capacity or that all players in the policy game need to move beyond self-interested advocacy. however, an overly broad definition of policy capacity is a problem. more important perhaps, health reform inevitably requires not just policy capacity but political leadership an...
