Food chain dynamics in the chemostat
Mathematical Biosciences, 1998The asymptotic behavior of a tri-trophic food chain model in the chemostat is studied. The Monod-Herbert growth model is used for all trophic levels. The analysis is carried out numerically, by finding both local and global bifurcations of equilibria and of limit cycles with respect to two chemostat control parameters: the dilution rate of the ...

Food Chain Concept in Food and Rural Policy
2009Food chain concept was firstly used as a private sector concept applied in order to optimise chain organisation and to create value along the chain. It is now becoming an approach to understand relations within a socio-economic area, both for economic and production aims and to gain a territorial and rural development perspective.

Radionuclides in the Food Chain
1988The task of this Chapter is to synthesize some of what has been presented in the excellent work preceding this summary, to comment on the present status of our capability to understand and to control radionuclides in the food chain, and to make some suggestions for actions in the future.

Fresenius' Journal of Analytical Chemistry, 1995
In spite of its abundant occurrence in the earth's crust (310 mg Rb/kg) and its composition of a stable (72.2%) and a radioactive (27.8%) isotope, rubidium (Rb) belongs to the forgotten ultratrace elements. The interest in this ultratrace element grew considerably after Rb deficiency experiments with goats had shown that their growth was depressed ...

Food waste in the Finnish food chain
Journal of Cleaner Production, 2014Abstract This study focused on mapping the volume and composition of avoidable food waste in the Finnish food production–consumption chain, and demonstrated that around 130 million kg of food waste are generated each year (23 kg per capita/year) from the household sector.

Iodine in the Food Chain [PDF]
, 1993 The incorporation of iodine into the food chain of soil and water on the one hand and of animals and humans on the other is of decisive importance for meeting human iodine requirements.

International Journal of Contemporary Hospitality Management, 1991
The causes of the recent increase in food contamination in the UK are examined. The scope extends beyond the normal focus on kitchen hygiene, to encompass malpractice at the supply end of the food chain. It is contended that the situation can be improved by making food policy consumer‐ rather than producer‐oriented; streamlining government ...

The energy which plants capture from the sun during photosynthesis may end up in the tissues of a hawk via a bird the hawk has eaten, the insects eaten by the bird, and the plant on which the insects fed. The plant-insect-bird-hawk system is called a food chain, and each stage a trophic level.
