感应智能垃圾分类箱 Han, Ke; Wu, Di; Liu, Baoxin This induction smart trash sorting bin combines a brand-new design concept with leading technology. The appearance design is exquisite and meticulous, the classification logo design is concise and eye-catching, and it has a sense of science and technology, which can stimulate people's awareness of environmental protection and consciously follow environmental protection rules. The outside of the sensor smart garbage sorting bin is designed with a relaxing pattern. It is divided into 4 different types of bins, which collect recyclable garbage, kitchen waste, hazardous garbage and other garbage, and are carefully designed.

ИК-спектроскопический анализ молекулярной и надмолекулярной структур композитов с полиэтиленовой матрицей при термических воздействиях «in situ» Холявкина, Д. Д.; Воробьева, Е. В. When creating innovative competitive composite materials, modifiers of different chemical nature (metals and their oxides, antioxidants, pigments, antislips, etc.) are introduced into the polymer matrix, which improve the operational and technological properties of the material. However, any modifier affects the molecular and supramolecular structure of the polymer, and its effect is particularly pronounced when exposed to heat. For example, metals with a change in valence and their oxides are catalysts for oxidation, while organic antioxidants, on the contrary, inhibit this process. The question arises: how to quickly assess the effect of the modifier on the polymer structure. We used the method of IR spectroscopy, a feature of the methodological approach was that the IR spectra were taken in the mode of heating, isothermal exposure and cooling of samples located in a thermal cuvette in the device. This approach to obtaining readings directly during a test experiment is called "in situ".

三种复合益生菌对菌群失调模型小鼠补偿生长和免疫功能的影响 Fu, Yujie To investigate the effects of three kinds of compound probiotics on compensation growth and immune function in dysbacteriosis mice, the mice model of antibiotic-associated dysbacteriosis was utilized in this study. These mice were divided into four groups, Group (intragastric administration of bacterium), Group (intragastric administration of bacterium), Group (intragastric administration of bacterium), as well as the normal and model control groups without receiving any probiotics, with a trial period of 30 days. The mice received five consecutive intramuscular injections with 40 mg/Kg hydrocortisone every other day since day 20 to induce immunosuppression. These results suggested that mice feeding with the compound probiotics (Ⅰ or Ⅱ) were able to significantly alleviate stress, compensate growth and enhance immunity of dysbacteriosis‐immunosuppression, comparing with the mice in model control group. This study provides a basis for facilitating the growth and enhancing the immunity in the livestock and poultry.
