Objective: This study aimed to detect the quality of wheat flour quickly and non-destructively. Methods: The online detection system for wheat flour quality was built in the experiment, which mainly includes the flowing four parts: micro near-infrared spectrometer integrated device, production line adjustable speed simulation device, spectrum online acquisition and control software and online modeling and analysis software. Different modeling algorithms were used to establish quantitative analysis models for moisture, ash and gluten, and the robustness of the online quantitative analysis model was optimized. The influence of different experimental conditions on the modeling results was analyzed. Results: Partial least squares regression （PLSR） algorithm is superior to multiple linear regression （MLR） and principal component regression （PCR） algorithm for quantitative analysis of moisture, ash and gluten. The best modeling effect was obtained by using quartz glass to collect wheat flour samples online, and the best ratio of 15 speed/integration time was 6 000 ms. Conclusion: The wheat flour quality online detection system based on near-infrared spectrum analysis technology realize the nondestructive and rapid online detection of wheat flour quality.

Molten salt-based nanofluid is a thermal storage and heat transfer medium for concentrated solar thermal power plants formed by adding nanoparticles to molten salt, which can enhance the thermal performance of molten salt. However, the nanoparticles tend to aggregate in nanofluids, causing changes in thermal properties. In this work, molecular dynamics simulations were used to study the effect of morphological characteristics of aggregates on the thermal conductivity and specific heat capacity of molten salt-based nanofluids. The results show that the aggregated nanoparticles cause a greater increase in thermal conductivity and specific heat capacity than dispersed nanoparticles. Additionally, the increase in fractal dimension leads to thermal conductivity reduction, while there is no clear correlation between the fractal dimension and specific heat capacity. New insights into the thermal properties of aggregated nanofluids are provided by analyzing the contribution of material components, heat flux fluctuation modes, and energy compositions. It is found that the thermal conductivity of aggregated nanofluids is mainly dominated by the base liquid and collision term. However, the specific heat is not related to the variation in the contribution of different energy compositions. Moreover, compared to the dispersed nanofluid, the increased specific heat capacity of aggregated nanofluids is attributed to the thicker semi-solid layer. This study provides guidance for the design and control of the thermal properties of molten salt-based nanofluids.

This paper summarized the effect of blood-letting puncturing combined with cupping therapy and nursing for the treatment of pain in a patient with stagnation of Liver-Qi and phlegm of hyperplasia of mammary glands. In addition to the nursing risk assessment and routine care, the blood-letting puncturing combined with cupping therapy was carried out based on the Traditional Chinese Medicine syndrome differentiation. The blood-letting puncturing combined with cupping therapy was proved to be effective in relieving the breast pain induced by mammary glands.

For the purpose of solving the problem of corrosion and scaling of the industrial circulating cooling water system, the biodegradable materials such as carboxyethylthiosuccinic acid (CETSA), acrylic acid - 2 - acrylamide - 2 - methylpropanesulfonic acid copolymer (AA/AMPS), polyepoxysuccinic acid (PESA), 2 - phosphonobutane - 1,2,4 - Tricarboxylic acid (PBTCA), sodium lauroyl sarcosinate (LS) and methylbenzotriazole sodium salt (TTA - Na), as well as zinc sulfate heptahydrate were used as components to compound composite scale and corrosion inhibitors. Meanwhile, the corrosion and scale inhibition properties of inhibitors were tested according to GB/T 16632-2008 and GB/T 18175-2014. Results showed that the optimized formula of scale and corrosion inhibitors was 10 mg/L CETSA, 14 mg/L AA/AMPS, 20 mg /L PESA, 4 mg/L PBTCA, 10 mg/L LS, 10 mg/L TTA - Na and 1 mg/L ZnSO4·7H2O (calculated using the content of Zn2+). In the case of the optimal inhibitor, the scale inhibition rate was 96.35%, the corrosion rate was 0.007 2 mm/a, the corrosi on inhibit ion rate was 99.68%, and the corrosion and scale inhibition performances were good and environment - friendly. Moreover, the electrochemical test results showed that the composite scale and corrosion inhibitor was a cathode type corrosion inhibitor. The SEM observation revealed that the composite scale and corrosion inhibitor could form a protective film on the surface of carbon steel, which could be adsorbed on the calcium carbonate crystals to suppress their development.

Long-term exposure to a microgravity environment leads to structural and functional changes in hearts of astronauts. Although several studies have reported mechanisms of cardiac damage under microgravity conditions, comprehensive research on changes at the protein level in these hearts is still lacking. In this study, proteomic analysis of microgravity-exposed hearts identified 156 differentially expressed proteins, and ubiquitinomic analysis of these hearts identified 169 proteins with differential ubiquitination modifications. Integrated ubiquitinomic and proteomic analysis revealed that differential proteomic changes caused by transcription affect the immune response in microgravity-exposed hearts. Additionally, changes in ubiquitination modifications under microgravity conditions excessively activated certain kinases, such as hexokinase and phosphofructokinase, leading to cardiac metabolic disorders. These findings provide new insights into the mechanisms of cardiac damage under microgravity conditions. [ABSTRACT FROM AUTHOR]

Summary: Plants delicately regulate endogenous auxin levels through the coordination of transport, biosynthesis, and inactivation, which is crucial for growth and development. While it is well‐established that the actin cytoskeleton can regulate auxin levels by affecting polar transport, its potential role in auxin biosynthesis has remained largely unexplored.Using LC–MS/MS‐based methods combined with fluorescent auxin marker detection, we observed a significant increase in root auxin levels upon deletion of the actin bundling proteins AtFIM4 and AtFIM5. Fluorescent observation, immunoblotting analysis, and biochemical approaches revealed that AtFIM4 and AtFIM5 affect the protein abundance of the key auxin synthesis enzyme YUC8 in roots.AtFIM4 and AtFIM5 regulate the auxin synthesis enzyme YUC8 at the protein level, with its degradation mediated by the 26S proteasome. This regulation modulates auxin synthesis and endogenous auxin levels in roots, consequently impacting root development. Based on these findings, we propose a molecular pathway centered on the 'actin cytoskeleton‐26S proteasome‐YUC8‐auxin' axis that controls auxin levels.Our findings shed light on a new pathway through which plants regulate auxin synthesis. Moreover, this study illuminates a newfound role of the actin cytoskeleton in regulating plant growth and development, particularly through its involvement in maintaining protein homeostasis via the 26S proteasome.
