One type of semi-buried mechanical barricade, the Salix psammophila sand barrier has been widely used in a wind-sand protection system in northwest China. However, the sand barriers are inevitably deteriorated under biodegradation, weathering, desorption-alternation, as well as the biological and abiotic factors, due to the exposure to the field environment for a long time. Decay and decomposition of sand barriers can alter the resource availability of dune soil, which is vital for understanding the biogeochemical process and nutrient cycling in desert ecosystems. Previous research has focused on the above-ground part of the sand barriers to intercept the wind and sand. But, it is still lacking in the ecological contributions and biogeochemical element cycling of the underground part of the desert soil during the long-term setting process. Therefore, this study aims to explore the effects of Salix psammophila sand barriers decay on the content and stoichiometric characteristics of the soil carbon (C), nitrogen (N), and P (phosphorus). The main environmental factors were determined to analyze the decay characteristics, soil physicochemical properties, and soil enzyme activities. The field test was conducted in the Hobq Desert (within the town of Duguitara, Inner Mongolia, China). The naturally degraded sample plots were selected in the windbreak and sand fixation areas adjacent to the roads with similar geographic characteristics and vegetation types for years 1, 3, 5, 7, and 9. The general situation of the sand barrier was determined at the experimental site. The test samples were collected and measured using the "space instead of time and in situ sampling". The results showed that the chemical composition of the barrier body decreased significantly (P<0.05), whereas, the soil moisture content and available nitrogen were improved during the process of Salix psammophila sand barriers decay. The extracellular enzyme activities of β-1, 4-glucosidase (BG) and β-1, 4-N-acetylglucosidase (NAG) increased first and then decreased, reaching the peak in the 5th year with the increase of time. In the first 7 years of decay, there was no change in the soil C/N ratio, but increased significantly at 9 years (P<0.05) with an increase of 41.20 %, compared with 1 year. The ratio of soil C/P and N/P increased significantly in the first 5 years, and they were 1.83 and 1.76 times higher at 5 years than at 1 year, respectively. The ratios of C/P and N/P were positively correlated with the dissolved organic carbon (DOC), available nitrogen (AN), organic carbon (SOC), total nitrogen (TN), and β-1,4-glucosidase (BG). By contrast, the ratio of C/N was negatively correlated with the β-1,4-N-acetylglucosidase, cellulose (Cel), and lignin (Lig), and only positively correlated with the mass loss rate (ML). Dissolved organic carbon and available nitrogen were positively correlated with the total carbon, total nitrogen, total phosphorus, and mass loss rate, respectively, but negatively correlated with the cellulose. The results of redundancy analysis further confirmed that cellulose and mass losses were the main factors affecting soil C, N, and P content and their stoichiometry. Therefore, the decay process of the Salix psammophila sand barrier can be expected to increase the soil C, N, and P content, indicating a long-term and effective control measure. These findings can provide a strong reference for the relationships between the decay process of Salix psammophila sand barriers and soil elements stoichiometry. Great contribution can be offered to the decision making on the Salix psammophila sand barriers in wind erosion protection and vegetation restoration in desert areas. [ABSTRACT FROM AUTHOR]

Using the NCEP 1°×1° reanalysis data produced by the U.S. Center for Meteorological and Environmental Prediction and the hourly precipitation data from the National Weather Station（national reference, basic and general weather station） and regional station（ground-based encrypted observation station） of the Yellow River Basin, the paper diagnosed and analyzed the process of flood-causing rainstorms that occurred in the middle reaches of the Yellow River Basin on July 10 and 11, 2018. The outcomes show that affected by the northwest movement of Typhoon Maria, the subtropical high is stable and moves less, and the low trough moves slowly, leading to long precipitation maintenance time and falling precipitation. The area is in the northeast-southwest direction; the main source of water vapor in the heavy rain area is typhoon Maria. Affected by the topography of the middle reaches of the Yellow River and the northwest airflow at mid-high latitudes, the trend of the water vapor flux convergence area is the same as that of the rainstorm area, 850-700 hPa It is the main water vapor transport layer of the rainstorm; the rainstorm area appears on the side of the warm area on the right side of the dense θse contour area in the middle and low layers, and there is a large value area of ?θse/?p>0 in the middle layer; the high and low jets have obvious coupling mechanism, the convergence of the middle and low levels and the overlap of the high-level divergence areas are the main reasons for the increase in precipitation intensity and the heavy rain at Qiaogouwan Station. The movement of the 200 hPa positive divergence area is earlier than that the movement of the low-level divergence area. Movement is indicative. The horizontal distribution of the frontogenesis function at 700 hPa is consistent with the distribution of precipitation. The horizontal distribution of the frontogenesis function value is consistent with the distribution of precipitation in the south and the north is large. The large value center of the frontogenesis function coincides with the center where the precipitation exceeds 100 mm. [ABSTRACT FROM AUTHOR]

This study aims to lay the foundation for the rational use of chicken manure resources and the production of high-quality organic fertilizers through the enrichment cultivation, screening and separation of high-temperature protein degrading bacteria. Due to the lack of protein-degrading bacteria and high-temperature bacteria in the process of chicken manure fermentation, the fermentation heating time is slow, the high temperature maintenance time is short, and the fermentation time is long. Enriched culture, purification and separation of high-temperature strains that efficiently degrade proteins under high-temperature conditions. 24 strains of high-temperature and highly efficient protein degradation bacteria were isolated and identified as belonging to 8 species, including Brevibacillus spp, Bacillus spp, and Pseudoxanthomonas spp. Inoculation of the prepared compound bacterial solution in chicken manure found that the the temperature rise rate in the experimental group with the bacterial agent was significantly faster than that in the control group. It reached the high temperature stage about 16h after fermentation, nearly 8h ahead of the blank group, and which was nearly 8 h earlier than that in the control group. And the FJ3 group, which was added with high-temperature protein-degrading bacteria. Compared with that in the control group, the high temperature period was prolonged by about 24 hours, and the duration reached 56 hours. The pH of the fermentation process decreased faster than that of the control group, the lowest pH value was around 5.5. The moisture content of the poultry dung reduced from 65% to about 20%, the proportion of N, P, K and other nutrients increased, and the fermentation product is loose and soft, with a strong acid flavor. Therefore, the addition of high-temperature protein-degrading bacteria could increase the temperature rise rate, prolong the period of high temperature, accelerate the ferment process of poultry dung, and reduce the loss of nutrients, which has great significance for the treatment of poultry dung.

Objective To observe the effect of dendrobium on the amelioration of excessive fat deposition in the liver cells of non-alcoholic fatty liver disease (NAFLD) mice, and to explore its mechanism. Methods Ten C57Bl/6J male mice were taken as the normal control group and fed with ordinary diet. The remaining 30 mice were fed with high-sugar and high-fat diet for 12 weeks. After the NAFLD models were established, they were randomly divided into the model group, low-dose and high-dose dendrobium groups, with 10 mice in each group. The mice in the low-dose and high-dose dendrobium groups were given 200 and 400 mg/( kg · d) dendrobium decoction by gavage, respectively. Both the mice in the model group and the normal group were given equal volume of normal saline for 14 weeks. After the treatment, the sta tus of the mice in each group, including body shape, weight, abdominal circumference, fur gloss, and activity level were observed. After the gavage, the mice in each group were fasted for 12 h, and blood was taken from the venous plexus under the eyes, and the serum TG, TC, AST and ALT were detected with a biochemical test kit. After the gavage, the mice were sacrificed, and the liver tissues were taken to observe the liver tissue pathology. PT-PCR was used to detect sterol regulatory element binding protein (SREBP-lc) mRNA and fatty acid synthase (FAS) mRNA in the liver tissues of mice in each group. Western blotting was used to detect the p-mTOR protein in the liver tissues of mice in each group. Results The body shape of the mice in the model group was significantly larger than that of the normal group, and their weight and ab dominal circumference also significantly increased. They moved freely, but their fur was rough and dull and easy to shed hair. The mice in the low-dose and high-dose dendrobium groups had normal activity, agile activity, normal spirit, and shiny fur. The serum TG, TC, AST and ALT levels of mice in the normal group, low-dose and high-dose dendrobium groups were lower than those in the model group (all P < 0. 05) . Mice in the model group had enlarged liver cells, more lipid droplets, and fatty cyst formation; the fatty liver transformation decreased in liver of the mice in the low-dose and high-dose dendrobium groups. The relative expression levels of SREBPlc mRNA and FAS mRNA in the liver tissues of mice in the normal group, low-dose and high-dose dendrobium groups were lower than those in the model group (all P <0. 05), and the relative expression ofSREBPlc mRNA and FAS mRNA of liver tissues in high-dose Dendrobium group was lower than that of the low-dose dendrobium group (all P < 0. 05). The relative expression of p-mTOR protein in the liver tissue of mice in the normal group, low-dose and high-dose dendrobium group was lower than that in the model group ( all P < 0. 05), and the relative expression level of p-mTOR protein in the liver tissues of the high-dose dendrobium group was low er than that of the low-dose dendrobium group ( P < 0. 05). Conclusion Dendrobium may regulate the mTOR signaling pathway to ameliorate the excessive fat deposition in the liver cells of NAFLD mice. [ABSTRACT FROM AUTHOR]

At present, most of the widely used critical liquid-carrying flow prediction models are taking vertical wells as research object, and as we do not consider the effect of deviation angle on liquid-carrying, a large deviation was caused between the predicted value of critical liquid-carrying flow and the actual situation in inclined gas wells. In order to judge whether there is a problem of fluid loading in inclined gas wells, based on the analysis of liquid-droplet force equilibrium theory, a new model for predicting the critical liquid-carrying flow of gas wells was established on the basis of considering the effect of droplet deformation and well deviation angle. According to the energy conservation equation, we deduced the functional formula between critical Weber number and droplet deformation parameters. Based on the hypothesis of ellipsoidal droplet, and considering the influence of droplet internal flow and droplet deformation, the drag coefficient of the ellipsoidal droplet is taken down by 15% of the calculation results for Shao Mingwang model. Compared with Turner model, Li Min model, Wang Zhibin model, Yang Wenming model and Belfroid model, it is found that the new model has a higher accuracy, with an increase of 14.49%~16.80% in calculation accuracy. It can correctly judge the liquid accumulation in gas wells, which is consistent with the actual situation in the field, and can effectively guide the safe and rational production of gas fields.
