It is well known that a one-unit increase in the final demand in one sector induces both direct and indirect products of each sector in the economies, and that the induced value-added and imports, if aggregated for all sectors of both countries, yields the same value as all initial increases in the final demand.
Some enzymes also have binding sites for small molecules, which are often direct or indirect products or substrates of the reaction catalyzed.
In a celebrated text in "Principles of Philosophy," Descartes writes, "It is certain that all the rules of mechanics belong to physics, to the extent that all artificial things are thereby natural... .......... [T]hey are thus the direct or indirect products of a technical activity that is as authentically organic as the flowering of trees.
In scenario planning indirect product impacts are helpful.
A Federal Department of Labor was the direct product of a half-century campaign by organized labor for a "Voice in the Cabinet," and an indirect product of the Progressive Movement.
It has been suggested that formate is an indirect product of the glyoxylate cycle and that formate dehydrogenase, Fdh1p, may be involved in the detoxification of formate in C. albicans upon phagocytosis by macrophages [37].
Given the results seen here, both these effects appear to be direct influences of the rust, either due to death of plant tissue or release of fungal metabolites, rather than an indirect product of the plant response.
In order to evaluate the renal oxidative stress, we evaluated the concentration of MDA, an indirect product of lipid peroxidation.
Dimethylsulphoniopropionate (DMSP) is a sulphur compound produced by most marine algae for numerous cellular functions [ 33], and is derived from methionine [ 33], an indirect product of photosynthesis [ 34].
Concentration of MDA, an indirect product of lipid peroxidation, was determined by the thiobarbituric acid reactive substance (TBARS) test, a technique commonly used in lipoperoxidation studies [ 18].
Measured parameters included: photosynthetic characteristics, pigment composition, thallus reflectance and intracellular concentrations of dimethylsulphoniopropionate (DMSP), an algal antioxidant that is derived from methionine, an indirect product of photosynthesis.
