The canopy width is a necessary variable for the growth of desert vegetation. Predicting the crown width of desert plant in different habitats can provide reference for the scientific management of desert vegetation. Taking the species of Haloxylon ammo⁃ dendron in the Gurbantunggut Desert as the research object, select 6 commonly （M1, M2, M3, M4, M5, M6) used regression mod‐ els, using tree height and ground diameter as survey factors, establish a canopy model of H. ammodendron in different habitats of highlands, gentle slopes, and flat lands. Perform regression analysis on the model using Origin and Anaconda software, select the op‐ timal model based on four fitting accuracy standards （R2 ，RMSE，MAE, and MAPE). The model fitting results indicate that： in the tree height -shrub crown width and shrub ground diameter models, the R2 values of the six regression models are all greater than 0. 5, the model fitting effect is good. M5（cubic polynomial model) is the optimal model for tree height crown width and ground diameter crown width in three different habitats. All six models have statistical significance （Sig. <0. 001), which has important reference value for predicting the crown size of H. ammodendron in the Gurbantunggut Desert, and provides a certain scientific basis for main‐ taining the ecology and vegetation restoration of the region [ABSTRACT FROM AUTHOR]

A series of three-dimensional attapulgites were prepared by using toluene diisocyanate (TDD as a coupling agent and diols with different chain lengths as bonding agents. The effect of the length of the diol segment and the molar ratio of TDT to diol on the adsorption of malachite green by three-dimensional attapulgite was an alyzed. The thermodynamic and kinetic characteristics of three-dimensional attapulgite adsorption of malachite green were studied. The results show that with polyethylene glycol 600 as the bonding agent, when the molar ratio of TDT to polyethylene glycol 600 was 1:0.5, the prepared three-dimensional attapulgite had the best adsorption performance on malachite green. The adsorption process was consistent with the Langmuir isothermal adsorption equation. The enthalpy change and entropy change were 5.14 kJ/mol and 41.40 J/(mol • K), respectively, which showed spontaneous physical adsorption and followed a quasi-second-order kinetic equation.

[Objective] The study aimed to find the main differential metabolites in four soy sauces ( two sauces produced from China and another two sauces produced from Japan), and to provide a theoretical basis and methodological reference for analyzing the metabolites in soy sauces. [ Method] Metabolites information was gathered by ultrahigh-performance liquid chromatography quadrupole-time-of-flight mass spectrometry ( UPLC-QTOF-MS), and statistical analysis of multivariate variable was conducted by MS-DIAL and XCMS. [Result] The relative abundance of arginine were 3. 42 x 10 7 and 3. 32 x 107 in JSl and JS2, respectively, which were significantly higher than in CSl and CS2 ( 0. 98 x 107 and 1. 72 x 107 ), and the harmane in JSl of Japanese soy sauce were 2.02 x 107, which were significantly higher than that in CSl and CS2 ( 1.16 x 107 and 0. 84 x 107 ). [ Conclusion]The relative content of arginine and harmane in Japanese soy sauce are significantly higher than that in Chinese soy sauce. [ABSTRACT FROM AUTHOR]

Objective To observe the risk factors and prevalence rate of hypertension in Bai ethnic group in Dali， Yunnan. Methods Bai ethnic minority villagers aged over 50 and been living in the villages in Dali for more than 6 months each year were recruited by cluster sampling and their blood pressure were taken．Data of the risk factors including occupation， smoking， drinking， family history，height and weight were collected and then analyzed with multiple factor logistic regression(P<0.05). Results The prevalence rate of all the villagers enrolled was 41.7%， with male prevalence rate being 41.5%，and female rate being 41.9%. Multiple factor Logistic regression analysis showed that age，obesity，family history，smoking and drinking were risk factors of the hypertension (P<0.05) . Conclusions The prevalence rate of hypertension in Bai ethnic adults is higher than some regions of China. The prevention and treatment of hypertension should be reinforced. [ABSTRACT FROM AUTHOR]
