Limiting Nutrient

Although plant strategies for acquiring nutrients have been widely studied from a functional point of view, their evolution is still not well understood. In this study, we investigate the evolutionary dynamics of these strategies and determine how they influence ecosystem properties. To do so, we use a simple nutrient-limited ecosystem model in which plant ability to take up nutrients is subject to adaptive dynamics. We postulate the existence of a trade-off between this ability and mortality. We show that contrasting strategies are possible as evolutionary outcomes, depending on the shape of the trade-off and, when nitrogen is considered as the limiting nutrient, on the intensity of symbiotic fixation. Our model enables us to bridge these evolutionary outcomes to classical ecological theories such as Hardin's tragedy of the commons and Tilman's rule of R *. Evolution does not systematically maximize plant biomass or primary productivity. On the other hand, each evolutionary outcome leads to a decrease in the availability of the limiting mineral nutrient, supporting the work of Tilman on competition between plants for a single resource. Our model shows that evolution can be used to link different classical ecological results and that adaptation may influence ecosystem properties in contrasted ways.

Recently a novel quantum information formalism — quantum adaptive dynamics — was developed and applied to modelling of information processing by bio-systems including cognitive phenomena: from molecular biology (glucose-lactose metabolism for E.coli bacteria, epigenetic evolution) to cognition, psychology. From the foundational point of view quantum adaptive dynamics describes mutual adapting of the information states of two interacting systems (physical or biological) as well as adapting of co-observations performed by the systems. In this paper we apply this formalism to model unconscious inference: the process of transition from sensation to perception. The paper combines theory and experiment. Statistical data collected in an experimental study on recognition of a particular ambiguous figure, the Schröder stairs, support the viability of the quantum(-like) model of unconscious inference including modelling of biases generated by rotation-contexts. From the probabilistic point of view, we study (for concrete experimental data) the problem of contextuality of probability, its dependence on experimental contexts. Mathematically contextuality leads to non-Komogorovness: probability distributions generated by various rotation contexts cannot be treated in the Kolmogorovian framework. At the same time they can be embedded in a “big Kolmogorov space” as conditional probabilities. However, such a Kolmogorov space has too complex structure and the operational quantum formalism in the form of quantum adaptive dynamics simplifies the modelling essentially.

Important Amount

It is specific for our modern society to consume an important amount of food transported from one part of the earth to another. A sustainable refrigerated transport is described by indicators like profitability, product quality, technological change, and environmental impact. Sustainable development is connected with the minimisation of irreversibilities. This is why exergy analysis is used as a powerful tool to obtain sustainable development. In this context, this chapter deals with the exergy analysis specific to the most common type of refrigerating plants on board ships. Regulations on old refrigerants, inducing technological change, are presented along with solutions for the replacement of the refrigerant R-22. The chapter also mentions the fishing industry where ammonia is the dominant refrigerant.

History Of Navigation

This paper falls roughly into three sections: the inter-relationship between economic forces, technological change and occupations, a brief history of navigation in occupational terms, and the present and future state of the occupation. The conclusions drawn may be open to discussion, since it presents a point of view and not a specific piece of research. It is restricted to the occupation of navigation in the Merchant Navy; naval and aircraft navigation appear to be very different as occupations.

AbstractFrom the point of view of the oppressed and the exploited in an iniquitous political economic order, technological change conceals more than what it reveals. The concealing of technology could be the ideological bias or intentions of its promoters or protagonists which is more often concealed than revealed in social theories and analysis of technological change. Using the poison gas explosion at the Union Carbide pesticide plant at Bhopal as a case in point, I will argue that this technological massacre of a city population can be read only as the concealing of the "real" nature of the technology of the so-called "Green Revolution" in India's agricultural modernization programme.

The aim of the publication is to answer the question: How will employment and working conditions change from the point of view of Industry 4.0 (I 4.0)? The digitization of production is a process that has been progressing extremely dynamically for several years now. The process is driven by the speed of technological change in I 4.0. In cyber–physical reality, the number and structure of employees and their qualifications are changing irreversibly and new working conditions are being created. In such a situation, there is a need to analyze the topic—both a challenge and necessity for scientists and practitioners because it is so very new. The publication is based on information from literature—an overview of scientific publications.
