Szent-Györgyi then turned to the study of organic compounds known to play a part in the conversion of carbohydrate breakdown products to carbon dioxide, water, and other substances necessary for the production of usable energy by the cell.
Several initiatives are underway to use cellulose-based feedstocks for the production of usable sugars for biofuels, biochemicals, and biopolymers (Jong et al. 2010).
The approach is applied on a residential scale cogeneration unit for the production of usable heat and electrical power.
The paper argues that, rather than an automatic outcome of the call for the production of usable science, iterativity is the result of the action of specific actors and organizations who 'own' the task of building the conditions and mechanisms fostering its creation.
The simple sugars which retain the chemical energy of lignocellulose are easily separated from the digestion products and more readily usable for animal or human food or for the production of chemicals and biofuels [ 7].
The I.A.E.A.'s inspectors said, "There are no indications that there remains in Iraq any physical capability for the production of amounts of weapon-usable nuclear material of any practical significance".
In addition, soybean is also an attractive crop for the production of biodiesel which produces more usable energy and less greenhouse gases than corn-based ethanol [ 5].
These case studies showcase innovative approaches to advancing girls' education, including a science, technology, engineering and mathematics (STEM) career mentoring programme; a mobile education scheme for girls; the production of washable and re-usable sanitary pads; scholarship initiatives; and more.
Then we turned to the production of usable objects like chairs, tables and cabinets, but these were designed in a deliberately neutral way, a criticism of consumer culture and the continuous drive for novelty.
For example, innovative work by the Keasling group has recently demonstrated that it is possible to metabolically engineer E. coli to produce large quantities of artemisinic acid, a usable precursor for semisynthetic production of the antimalarial sesquiterpenoid natural product and medically relevant drug artemisinin (Chang et al. 2007).
