In this paper, a novel fluorescent sensor for glucose detection based on fluorescent iron clusters (Fe NCs) and glucose oxidase is developed. With the increase of glucose concentration, the red fluorescence of iron nanoclusters decreases gradually, and the glucose content can be detected in the range of 0– 100 μmol·L–1. In addition, in order to facilitate the detection of glucose, ...

The frequency of their own oscillations of sprung and unsprung masses was compared using the generally recognized values of the “golden” car parameters and data obtained through experiment with ground-based laser scanning.

In order to verify the effectiveness of the three-stage potato soil separation device, a comparative simulation should be carried out using the EDEM-Recurdyn simulation method. The results showed that the design of the three-stage potato soil separation unit could reduce damage to potato tubers.

A late start has slowed the development of potato harvesters in China. Although research and development by companies such as MENOW and Hongzhu have raised the level of equipment in this field, problems remain.

The construction industry is a pillar industry of the national economy, and the scale of the construction industry has expanded rapidly in recent years. However, there is a problem of poor profitability in the construction industry. It was found that the main reason for the poor profitability of the construction industry is the problem of project cost management, and the main ...

An analysis of the operational properties of elastic bush-pin couplings is presented. Methods for studying the stress-strain state of elements of elastic leaf couplings are presented. Algorithms have been developed to perform verification and design calculations of elastic leaf couplings.

The article describes a developed software module for automating the selection of replacement wheels for a guitar used on a universal milling machine. The module is implemented in MS Excel based on a macro command, the algorithm of which sequentially goes through all the options from a given set of wheels to find the optimal solution. The module can be adapted to various CAD ...

This paper discusses the effects of processing parameters on the grinding process of ceramic products. The article also describes the processing process and tools. Attention is also paid to acoustic emission.

The rate of progress in information modelling in the Republic of Belarus is not being achieved at the desired level. The concept of a BIM manager's role during the construction phase of a large project in building and construction is described in this paper.

An example is given of calculating the service life of a combined tool for machining a stepped hole, which proves the inappropriateness of assigning tool cutting modes to a cutting element with a minimum minute resource. It is proposed to pre-assign cutting modes for tools of the same type according to the cutting element with the longest cutting length, establishing a replacement ...
