Essential Variables and Breath Types
2017‘Essential Variables and Breath Types’ describes the eight types of mechanical breath in terms of their five essential variables: triggering, cycling, controlling, targeting, and baseline pressure. This chapter begins with detailed descriptions of these variables, including their definitions, mechanisms, and options.

Essential oil variability of Minthostachys verticillata
Biochemical Systematics and Ecology, 1996The leaf volatile constituents of Minthostachys verticillata from various phytogeographic areas of Argentina were steam distilled and analyzed by GC and GC/MS. The composition of the oil was extremely variable from one population to another, leading to the conclusion that there are several chemotypes in this species.

Habit-Based Regulation of Essential Variables
Artificial Life 14: Proceedings of the Fourteenth International Conference on the Synthesis and Simulation of Living Systems, 2014A variety of models have been developed to investigate “homeostatic adaptation,” a mechanism inspired by Ashby’s homeostat, where a plastic control medium is reorganized until one or more essential variables are maintained within predefined limits. In these models, “habits” emerge, defined as behavior-generating mechanisms that rely upon their own ...

An operational definition of essential biodiversity variables
Biodiversity and Conservation, 2017The concept of essential biodiversity variables (EBVs) was proposed in 2013 to improve harmonization of biodiversity data into meaningful metrics. EBVs were conceived as a small set of variables which collectively capture biodiversity change at multiple spatial scales and within time intervals that are of scientific and management interest. Despite the

Essential Ecosystem Service Variables
2016The exponential development of the ecosystem services field has led to a wide range of variables that have and can be measured. Yet, this wide array of information is oſten overwhelming: guidance is needed on which ecosystem service variables should be measured and monitored.

Interoperability of Argo Essential Climate Variables
Argo is an international observation array of approximately 4 000 autonomous profiling floats measuring oceanic Essential Climate Variables (ECV) consisting of physical (pressure, temperature and salinity) and biogeochemical (dissolved oxygen, pH, nitrate, chlorophyll-a, downwelling irradiance and suspended particles) variables, from 2000-meter depth ...Delphine Dobler +3 more
