Gross primary production (GPP) is the amount of chemical energy, typically expressed as carbon biomass, that primary producers create in a given length of time.Some fraction of this fixed energy is used by primary producers for cellular respiration and maintenance of existing tissues (i.e., "growth respiration" and "maintenance respiration").
The helix of sustainability - the Carbon cycle ideal for manufacture and use The international recycling symbol - not nature identical.. The helix of sustainability is a concept coined to help the manufacturing industry move to more sustainable practices by mapping its models of raw material use and reuse onto those of nature.
In ecology, the term productivity refers to the rate of generation of biomass in an ecosystem, usually expressed in units of mass per volume (unit surface) per unit of time, such as grams per square metre per day (g m −2 d −1).
The triple helix model of innovation, as theorized by Etzkowitz and Leydesdorff, is based on the interactions between the three following elements and their associated 'initial role': [9] universities engaging in basic research, industries producing commercial goods and governments that are regulating markets.

Triplex DNA structure. The arrows are going from the 5' end to the 3' end. (Triple-stranded DNA (also known as H-DNA or Triplex-DNA) is a DNA structure in which three oligonucleotides wind around each other and form a triple helix.
Chagas disease, also known as American trypanosomiasis, is a tropical parasitic disease caused by Trypanosoma cruzi.It is spread mostly by insects in the subfamily Triatominae, known as "kissing bugs".
