Subject. This article discusses the issues related to the technological infrastructure of agriculture, improving the efficiency of energy resources, minimizing labor and material costs, and ensuring the continuity of the production process. Objectives. The article aims to study methods to improve the technological infrastructure of agricultural enterprises in the digital economy terms. Methods. For the study, we used the methods of comparison and classification. Results. The article describes patterns of development of technological processes in agriculture in the digital economy. Conclusions. The technical fitting-out of agriculture in the digital economy should be considered as a set of measures to prepare the industry for the production of high-quality products, which implies the use of digital technologies that minimize human participation in the production process.

Concentrated Solar Energy

Gasification of coal, biomass, and other carbonaceous materials for high-quality syngas production is considered using concentrated solar energy as the source of high-temperature process heat. The solar reactor consists of two cavities separated by a SiC-coated graphite plate, with the upper one serving as the radiative absorber and the lower one containing the reacting packed bed that shrinks as the reaction progresses. A 5-kW prototype reactor with an 8 cm-depth, 14.3 cm-diameter cylindrical bed was fabricated and tested in the High-Flux Solar Simulator at PSI, subjected to solar flux concentrations up to 2300 suns. Beech charcoal was used as a model feedstock and converted into high-quality syngas (predominantly H2 and CO) with packed-bed temperatures up to 1500 K, an upgrade factor of the calorific value of 1.33, and an energy conversion efficiency of 29%. Pyrolysis was evident through the evolution of higher gaseous hydrocarbons during heating of the packed bed. The engineering design, fabrication, and testing of the solar reactor are described.

Quality And Outcomes

Our ability to deliver high-quality cancer care is increasingly influenced by our ability to understand and manage the costs of care. Though there are considerable differences in the ways healthcare is financed and administered in different nations, there is a common need to deliver high-quality care at sustainable costs. This chapter reviews recent estimates of the aggregate costs of cancer care, discusses methods for determining cost-effectiveness or value in cancer care, provides a framework for understanding the components of cost at the societal and individual levels, and discusses efforts to control cost while preserving or improving both quality and outcomes.

Further Development

At present, charcoal briquette fuel, a source of heat energy and mostly made from agricultural waste materials, are popular in the markets because of their high constant heat output. It helps reduce pollution, and produce no sparks while burning, but varied due to different types of materials, burning protocols, temperature, and pressure used. In this study, the research team have studied the characteristics of high quality fuel briquettes for possible further development of standard indicators of briquette fuel production process. In the study, key factors of the Charcoal fuel features composed of high qualities of physical characteristics and electrical induction. Activated carbon and coconut shell charcoal types were showed to be great materials. The production process involved aerobic burning at 800-900oC for at least 3 hours, grinding and mixing with starch binder. The briquettes’ electrical conductivity was especially lower than 10 kΩ. High heat production was obtained at least 6000 Cal/g while ground charcoal possessed with the sizes were varied. Under microscopy, the charcoal particle sizes were in a range of 50-100 μm for 30-50% (w/w), size of 10-50 μm for 20-40% (w/w) and distinctive numbers of holes greater than 300 μ to 1 mm were rarely observed. Therefore, with key characteristics of charcoal briquette fuel, it could be further applied for development the indicator as well as instruments to measure the quality of the briquette.
