The differential equations were solved numerically on a discretized grid (in 2-dimensional (2D) in contrast to the 3D simulations in Cx3D) of 150 × 150 cells with the explicit Euler method for calculating the time evolution of the substance concentrations.
This approach is very suitable for studying the soil/plant interface, and for semi-quantitative analysis of the evolution of polyphenolic substances during root evolution.
In vitro tests could track the evolution of toxic substances as a fire grows, assess the safety of building materials, and provide more accurate safety information for fire professionals, the researchers concluded.
Additionally, post-copulatory sexual selection favors the evolution of seminal substances that further enhance fertilization chances by influencing female physiology [2], which thereby fall within the definition of allohormones [3].
Data concerning the smuggling flows intercepted by Italian authorities are used to carry out detailed studies about the evolution of the trafficking of illicit substances.
Vargas-García et al. (2007) determined the influence of microbial inoculation (Bacillus shackletonni, Streptomyces thermovulgaris and Ureibacillus thermosphaericus) and co-composting material on the evolution of humic-like substances during composting using the windrow method and concluded that the benefits of inoculation depended on the properties of the applied raw materials and microorganisms.
The evolution and incorporation of the substance lignin into the cell walls of plants provided strength and support.
The differential equations describing the time evolution of the quantity Q i of a substance in liver, fat, and poorly perfused or well perfused tissues were of the form where F i is blood flow through tissue i (i – 1,..., 4), V i is its volume, P i is the corresponding tissue/blood partition coefficient, and Cart is the arterial blood concentration.
Future studies need to examine alternative explanations for a higher rate of evolution of queen-specific substances, such as an involvement of such compounds in mating.
