为了开发高效、环保的食用油脱色剂，以一种环保方法（半干法）生产的蒙脱土为研究对象，研究其在不同脱色条件（脱色温度、脱色时间和脱色剂添加量）下对大豆油、葵花籽油和菜籽油品质的影响。结果表明：该蒙脱土具有吸附色素和过氧化物从而降低油脂红值和过氧化值的作用，与脱色前相比，大豆油、葵花籽油和菜籽油的红值最大降幅分别为77.4%、92.3%和87.2%，过氧化值最大降幅分别为82.7%、83.2%和91.2%；蒙脱土用于3种植物油的脱色，植物油中总甾醇和总生育酚含量下降，而酸值总体上缓慢上升。进一步研究发现，在相同的脱色条件下，蒙脱土对大豆油、葵花籽油和菜籽油的酸值、总甾醇含量和吸油率的影响结果均优于活性白土，尤其是吸油率几乎是活性白土的一半。蒙脱土可替代活性白土用于对色泽要求不是很高的植物油脱色中。 The effects of montmorillonite produced with the semi-dry method on the qualities of soybean oil, sunflower seed oil and rapeseed oil under different bleaching conditions (bleaching temperature, bleaching time and dosage) were investigated to develop an efficient and environmentally friendly bleaching agent for edible oil. The results showed that the bleaching agent(montmorillonite) had the function of adsorbing pigments and peroxides to reduce red value and peroxide value. Compared with oils before bleaching, the red value of soybean oil, sunflower seed oil and rapeseed oil was decreased by 774%, 92.3% and 87.2% (the largest reduction), respectively, the peroxide value was decreased by 827%, 832% and 912% (the largest reduction), respectively. When montmorillonite was used for the bleaching of three kinds of vegetable oils, the content of total sterols and total tocopherols in vegetable oils decreased, while the acid value increased slowly. Further research found that the effect of montmorillonite on the acid value, total sterol content and oil absorption rate of soybean oil, sunflower seed oil and rapeseed oil was better than that of activated clay under the same bleaching conditions, especially the oil absorption rate was almost half of that of the activated clay. Montmorillonite can be used as a substitute for activated clay in the bleaching of vegetable oils where the colour requirements are not very high.

Objective To explore the diagnostic accuracy and correlation of Vesical Imaging-Reporting and Data System (VI-RADS) and apparent diffusion coefficient (ADC) value histogram in muscle-invasive bladder cancer (MIBC) and non-muscle-invasive bladder cancer (NMIBC). Methods Multiparametric MRI of 81 patients with pathologically confirmed bladder cancer after transurethral resection of bladder tumors or radical cystectomy was retrospectively analyzed. Two radiologists scored all MRI examinations according to the VI-RADS criteria and ADC histogram parameters were obtained. Differences of VI-RADS and quantitative parameters between MIBC and NMIBC were evaluated. The diagnostic performance of the VI-RADS, ADC histogram parameter with statistically significant difference and combined diagnosis were evaluated for predictive ability of each model using the receiver operating characteristic (ROC) curves. Results of 81 patients including 40 (49.4%) MIBC and 41 (50.6%) NMIBC, 53 (65.4%) lesions with VI-RADS≥3 points, and 28 (34.6%) lesions with VI-RADS<3 points were analyzed. VI-RADS had the highest area under the ROC curve (AUC) of 0.903 among all parameters. The ADCmin, ADCmedian, ADCmean, 10% ADC (10th percentile ADC value), 25% ADC (25th percentile ADC value), 75% ADC (75th percentile ADC value), 90% ADC (90th percentile ADC value) of MIBC were significantly lower than those of NMIBC and were negatively correlated with the VI-RADS score (r=-0.439, -0.526, -0.305, -0.368, -0.547, -0.527, -0.396, all P<0.05) whereas kurtosis and entropy of MIBC were significantly higher than that of NMIBC and had positive correlation with the VI-RADS score (r=0.593, 0.296; P<0.05). VI-RADS+75% ADC (P=0.038), VI-RADS+ADCmedian (P=0.018), and VI-RADS+ADCmean (P=0.029) showed statistical differences compared to VI-RADS alone with the highest AUC value obtained by combining ADCmedian with VI-RADS (AUC=0.950). Conclusion VI-RADS and ADC histogram analysis can effectively. discriminate between MIBC and NMIBC. ADC histogram can supplement VI-RADS. [ABSTRACT FROM AUTHOR]

This study was to investigate the effects of plant essential oils from different sources on the growth performance of piglets, and to provide scientific basis for the application of plant essential oils in piglet feeding and feed production. In experiment 1, 384 PIC weaned piglets with body weight (7.90±0.46) kg were randomly divided into 4 groups with 4 replicates of 24 piglets each. The control group was fed commercial diet without antibiotic and plant essential oil, and the experimental group was fed essential oil R, essential oil A and essential oil B, respectively. The feeding trial lasted 32 days. In Experiment 2, 320 PIC nursery piglets with body weight (10.92±0.53) kg were randomly divided into 4 treatment groups with 4 replicates of 20 piglets each. The control group was fed commercial diet without antibiotic and plant essential oil, and the experimental group was fed a certain amount of essential oil R, essential oil A and essential oil B, respectively. The feeding trial lasted 23 days. The results of experiment 1 showed that compared with the control group, essential oils R and B could significantly reduce the F/G of weaned piglets (P<0.05), and the F/G of essential oil R was the lowest. In addition, only essential oil R can significantly reduce the diarrhea rate of weaned piglets (P<0.01). The results of experiment 2 showed that the F/G of nursery piglets with essential oil R was significantly lower than that of the control group and other experimental groups (P<0.05). During the experiment, there was no significant difference in diarrhea rate among all treatment groups (P>0.05). In addition, several essential oils had no significant effect on the hair condition and skin color of piglets (P>0.05). In conclusion, adding R essential oil to the diet can significantly improve the production performance of weaned and nursery piglets, and the effect is better than that of A essential oil products and B essential oil products.

[Objective] The aims of this study are to analyze the quantitative relationship between runoff depth. soil erosion, and factors such as catchment area and slope to provide a scientific basis for the construction of physical models of soil erosion and the calibration of their parameters. [Methods] Based on measured field data of natural rainfall on runoff plots under different surface conditions, a multiple parameters nonlinear estimation model for annual rainfall runoff depth and soil erosion was established. [Results] The threshold of rainfall generating runoff initially decreased and then increased with the catchment area and slope before showing a trend of increasing followed by decreasing. The annual runoff depth (Y1) and annual soil loss (Y2) showed a pattern of first increase and then decrease with the increase in area. Y1 initially decreased and then rapidly increased with the slope while Y2. continuously increased with the slope. Both Y1, and Y2. increased with the increase in annual rainfall. When the slope arca increased to 130 square meters, both Y1, and Y2 reached to their maximum values. When the slope was 13.5 degrees. Y1 reached to its minimum value. The multi-parameter nonlinear regression estimation model for Y1, was highly accurate. with 70% of the data points having a relative error within±30%. [Conclusion] The interaction between catchment area. slope, and annual rainfall is the most significant in affecting annual rainfall runoff depth and erosion amounts. There exists a critical catchment area and a critical slope value for annual runoff depth and erosion amounts. [ABSTRACT FROM AUTHOR]

30 provinces in China from 2006 to 2019 were studied, the Super-efficiency DEAML model and global spatial autocorrelation analysis method were combined to re-measure the actual logistics carbon emission efficiency and its overall characteristics in China, which based on the new assessment criteria for carbon emissions. The exploratory space-time data analysis method and related measurement models were further introduced to explore the space-time dynamic evolution characteristics of logistics carbon emission efficiency and its impact on convergence. The results suggest that: ①The efficiency of logistics carbon emissions is at a medium level in China and exists spatial agglomeration. The average is high in the east and low in the west. Increasing returns to scale exists in most provinces. Interannual variation shows a dynamic growth trend, and is greatly influenced by technological progress. ②The local spatial structure of logistics carbon emission efficiency differs from the direction of spatial dependence, The logistics carbon emission efficiency presents strong spatial integration among neighboring provinces, and has transfer inertia and path locking during dynamic evolution. ③ Logistics carbon emission efficiency has no σ convergence and has β convergence and club convergence. Regional differences, logistics agglomeration level and degree of informatization are the main influencing factors of conditional β convergence, there is significant club convergence in areas with more tortuous temporal and spatial evolution of logistics carbon emission efficiency.

【Objective】To clarify potato blackleg disease source of infection in Ulanqab City,Inner Mongolia,and provide the basis for formulating effective prevention and control measures for potato blackleg disease.【Methods】The pathogen isolation,pathogenicity identification,molecular identification and soil survival tests of potato blackleg disease were carried out. Through pot experiment and field experiment,seven treatments were set up to investigate the occurrence of potato blackleg disease in the soil of continuous cropping land,seed potatoes of diseased land and diseased residues,and analyze and verify the differences in incidence rate of different treatments.【Results】The incidence rate of potato blackleg harvested in diseased areas and planted as seed potato over winter was 40.00%. Pectobacterium atrosepticum was isolated from the disease residue buried in soil after overwintering,and the incidence rate was 43.33% in the experiment of planting disease-free potato after the disease residue was planted in the disease-free soil. The incidence rate of disease-free potato was 6.67% in the previous diseased plots. The amount of pathogenic bacteria in unsterilized soil gradually decreased with the extension of time,and no longer survived after two months at normal temperature,and no longer survived after four months at -20 ℃. The results indicated that P. atrosepticum could survive the winter in the disease residual and become the primary infection source in the second year. The pathogenic bacteria in diseased soil were related to the occurrence of disease,but the bacteria free in cultivated soil could only survive for two months at natural temperature.【Conclusion】 The primary infection source of potato blackleg disease in Ulanqab City,Inner Mongolia is the infected seed potato and the disease residual after winter,and the amount of bacteria carried by the seed potato is an important factor affecting the occurrence of the disease.
