The influence of sand processing on the strength properties of the final product, as well as cost reduction due to a decrease in the transport costs of this material, was studied.

In this paper, a radar absorbing metamaterial structure is designed, which consists of an upper layer of resistance film and a bottom layer of metal base plate, and the middle dielectric layer is omitted. The thickness of the resistance film is 100 nm, and the thickness of the metal plate is 1mm. The calculation results of CST Microwave Studio 2021 electromagnetic simulation ...

Resistive film is a class of films with resistive properties, which can be used in the manufacture of wave-absorbing metamaterials. The resistive film metamaterial absorber has the advantages of wide absorption frequency band and thin absorber thickness [1]. It has broad application prospects.

The current clinical diagnosis of depression in the medical community relies on selfrating scales and physician interviews, but this approach is limited by the expertise of clinicians and the uneven distribution of medical resources. This paper proposes the use of video multimodal techniques in clinical diagnosis, aiming to improve the efficiency and accuracy of depression detection ...

The problem of indoor heat supply in industrial workshops in high latitude areas in winter is complex. The energy consumption of air conditioners used in most workshops is huge. In this paper, an innovative industrial low carbon air conditioning design based on the concept of “nonuniform thermal environment” is proposed. Through orthogonal experiment and three-level evaluation, ...

As a new type of nano-materials, metal nanoclusters have gained wide attention in chemistry, materials, biology and so on.In this project, the blue green fluorescent carbon nanomaterials with rich functional groups will be prepared by hydrothermal synthesis technology, using natural biomolecular bovine serum protein as precursor BSA@CDs. A new type of carbon nano coated silver ...

Ulcerative colitis (UC) is a chronic non-specific intestinal disease, which has the characteristics of long course and easy recurrence. In recent years, more and more attention has been paid to the role of plant polysaccharides in the prevention and treatment of ulcerative colitis. Therefore, in this study, pectinase and papain were added to the extraction of guava, and the ...

The content of bilirubin is an important index to evaluate human health. A special nanocomposite was designed and constructed in this project. The content of bilirubin was detected by the change of fluorescence ratio signal generated when it was combined with bilirubin. Finally, the test paper is prepared to realize the convenient detection of bilirubin.

This project provides the theoretical and experimental basis for the industrial production of Weiqiao alumina red mud, and at the same time fundamentally solves a series of problems such as waste of resources, environmental pollution and storage costs caused by red mud stockpiling, so as to truly achieve sustainable economic development.
