Recognition of the parallels between animal life and flame provided the impetus to view life as combustion. Animal digestion and metabolism experiments revealed principles of nutrient sources of energy, the relation of chemical content to absorbed nutrient value, respiratory quotient, and biological value. Measurements of heat loss by animals revealed dramatic, >30-fold, differences in mass spe...

Being both a poison and cure for many lifestyle non-communicable diseases, food is inscribing itself into the prime focus of precise medicine. The monitoring few groups nutrients crucial some patients, methods easing their calculations are emerging. Our proposed machine learning pipeline deals with nutrient prediction based on learned vector representations short text–recipe names. In this stud...

Plant roots exude numerous metabolites into the soil that influence nutrient availability. Although root exudate composition is hypothesized to be under selection in low fertility soils, few studies have tested this hypothesis in a phylogenetic framework. In this study, we examined root exudates of three pairs of Helianthus species chosen as phylogenetically-independent contrasts with respect t...

In this study we evaluate the profitability of nutrient abatement measures in eutrophied coastal areas exposed to a risk of frequent oil spills. The case studied is the Gulf of Finland, which forms part of the Baltic Sea. We present a dynamic model that integrates land loads of nitrogen and phosphorus, cost of nutrient abatement measures in agriculture, nutrient dynamics in the sea basins adjoi...

In South Africa during the past four decades considerable research has taken place on the nutrient requirements of sugarcane. Consequently marked changes have occurred in patterns of fertilizer use. The value of N, P and K fertil~zers for cane production is reviewed using field experimental data. Correlations established between soil and leaf analysis and crop responses to various nutrients are...
