A Comparison of Wireless Devices for Terahertz Imaging Applications

As technology advances, notable scientific research accomplishments have been made. Terahertz (THz) waves have been seen to have endless potential applications that could further improve the current limitations of other frequency bands for imaging applications. Currently, THz waves display great potential in various applications due to their noninvasive and nonionizing features. However, the THz band has not been technically well established. This paper focuses on a comparative survey of the current methods applied in THz imaging in the field of medical and industrial security applications. Different types of methods, findings, advantages, and challenges of surveys ranging from 2016 to 2021 were discussed for both medical and industrial security applications to deepen the understanding of the latest trends, research, and technologies to have efficient THz imaging systems.

Regulation of nature management with the application of fiscal methods

The purpose of the article is to develop and apply the concepts and mechanism of fiscalization to the processes of managing the collection of payments from business entities to the budget for environmental offenses. The research methodology - application of the resource approach to the defini- tion of concepts, abstract-logical, system-structural and comparative analysis, ranking. The scientific novelty. The mechanism of fiscal management of nature users for their environmental pollution is revealed; the peculiarities of the calculation of the ecological tax, the distribution of the amounts of the current tax between the state and local budgets are indicated; applied innovations are substantiated taking into account the factor of ownership of natural resources. Conclusions. The need for environmental fiscalization is due to the environmental situation in the country, the fiscal system, energy and industrial security, pricing policy, business activity, the country’s international obligations and other factors. Key words: management, fiscal, in the use of nature, property, people, waste, pollution, rates, natural objects.
