Based on the sol-gel technology, three kinds of 10mg/cm³ CHO foam were prepared through different drying methods, and the microscopic morphology, pore structure distribution and mechanical properties of the foam were tested and analyzed. The results show that the cellulose triacetate(TAC)foam prepared by supercritical drying technology has the best mechanical properties, its elastic modulus is 3.50 X 104 Pa, and the elastic modulus of TAG foam prepared by freeze drying is 3.38 X 104 Pa. The TMPT A (polytrimethylolpropane tri acrylate) foam obtained by freeze-drying has the worst mechanical properties, and its elastic modulus is only 0.36 X 104 Pa. The pore size in the supercritically dried TAG foam is small (a few nanometers to more than ten nanometers), and the pore size distribution is relatively uniform. The pore size of freeze-dried TAC foam is enlarged (on the order of tens of nanometers)and the pore size distribution is wider. The freeze-dried TMPTA foam has the largest pore size (a large increase in pores on the order of hundreds of nanometers)and the widest pore size distribution. [ABSTRACT FROM AUTHOR]

The geochemical characteristics and genesis of selenium are of increasing interest in soil geochemistry research, as there exist fundamental problems in the development of selenium-enriched agricultural products. Therefore, this study performed a comprehensive analysis of data statistics using 43185 surface soil samples obtained in southeast Guizhou. The results showed that the geometric mean of selenium in the soil is 0.49 μg/g; the mean value of selenium in the black shale of cultivated soil is 1.55 μg/g, which is > sandstone (siliceous; 1.22 μg/g) > carbonaceous limestone (0.66 μg/g) > phyllitic slate (0.60 μg/g) > mudstone (0.58 μg/g) > dolomite (0.54 μg/g) > diabase (0.52 μg/g) > granite (0.48 μg/g) > variegated sand (gravel; 0.47 μg/g) > limestone (0.43 μg/g) > slate and metamorphic tuffite (0.42 μg/g) > purple sandstone (0.32μg/g) > mud, gravel, and sand (0.27μg/g). This indicates that the average content of selenium in soil is closely related to the parent rock. Meanwhile, combined with heavy metal elements in the area of an arable land soil pollution risk assessment, the cultivated land with black shale, sandstone (siliceous), carbonaceous limestone, mudstone, and dolomite was divided into high-grade and low-grade selenium-rich potential areas. The results of this study will provide a scientific basis for the development of selenium-rich agriculture in mountainous areas [ABSTRACT FROM AUTHOR]

The germanium content and quality grade characteristics of germanium-rich soil in cultivated land of the Qiandongnan prefecture were determined in this study through the investigation and evaluation of the surface soil geochemistry and the material sources and causes of germanium-rich soil were discussed. The results obtained were as follows: (1) the germanium content in the surface soil of the area was 0.13–9.21 mg/kg, and the arithmetic average was 1.54 mg/kg. (2) The germanium-rich farmland in the area was 1794.30 km², accounting for 40.17%. The environmental comprehensive grade of germanium-rich farmland is mainly for priority protection with an area of 1167.35 km², accounting for 65.06%. The safe use category is second with an area of 593.38 km², accounting for 33.07%. The strictly controlled farmland is less with an area of 33.57 km². (3) The main source of germanium in the soil is hydrothermal action or hot water activity that causes germanium to intrude and accumulate on the Earth’s surface. Ge is positively correlated with the soil Pb and Zn content, negatively correlated with N and organic matter, and weakly and positively correlated with other elements, suggesting that Ge is less affected by man-made materials.

Accurate and high-resolution precipitation data will help in obtaining an accurate monitoring of drought development spatially and temporally. In such an occasion, the quantitative precipitation products bear the potential advantages of monitoring droughts continuously over a wide-span space coverage, compared to traditional ground-based meteorological data. Three quantitative precipitation products were selected in this study to access their accuracies and drought monitoring potentials in Huaihe River Basin for their suitability in calculating the Standardized Precipitation Index (SPI). They are Multi-Source Weighted-Ensemble Precipitation (MSWEP), Climate Hazards Group Infrared Precipitation with Station (CHIRPS) and Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks-Climate Data Record (PERSIANN-CDR).The precipitation data from 27 meteorological stations in Huaihe River Basin from 1983 to 2016 were collected to test the accuracy of monthly accumulative precipitation data of three quantitative precipitation products. The SPI was used as the drought indicator. The Correlation Coefficient (r), the Root Mean Square Error (RMSE), the Critical Success Index (CSI), and the drought level monitoring Accuracy (ACC) were used as evaluation indicators to evaluate the drought monitoring potential of the three quantitative precipitation products (MSWEP, CHIRPS and PERSIANN-CDR). The results showed that: 1) All three quantitative precipitation products underestimated the actual precipitation both in monthly-, seasonal-, and annual-scale; The accuracy of MSWEP outperformed the other two products, in the sense that, the r values of MSWEP reached 0.92-0.97 and the RMSE values were 26.38-124.73 mm; The accuracies of CHIRPS with resolution of 0.05°×0.05° was similar to that of the resolution of 0.25°×0.25°; Also CHIRPS and PERSIANN-CDR had similar accuracy performances; 2) For the estimation of extreme shortage of precipitation, the MSWEP also bears the highest accuracy compared to the other two products, in the sense that the RMSE values are less than 50% than the other two products. In the month of extreme precipitation shortage, the three quantitative precipitation products generally overestimated the amount of precipitation compare to the observed precipitation values. 3) MSWEP's overall performance in drought monitoring was better than other products; the monthly SPI, seasonal SPI and annual SPI calculated by MSWEP had higher accuracies (r≥0.92, RMSE≤0.39), higher accuracies in drought month identification (CSI≥0.89) and higher accuracies in drought level identification (ACC≥80.3%). In case of CHIPRS or PERSIANN-CDR, the CSIs and ACCs in the three time scales were high for the three time scales. It revealed that those two products could also be used for watershed drought monitoring. 4) MSWEP was much more accurate in monitoring different drought levels, especially for that of extreme drought level. It’s ACC for determining various drought levels was higher than CHIRPS and PERSIANN-CDR; 5) All the three quantitative precipitation products showed excellent drought monitoring potential in the typical drought events in the Huaihe River Basin; MSWEP identified the spatio-temporal development process of typical drought events from February to June in 2000 more accurately; Compared with the typical drought events monitoring results based on precipitation data of meteorology stations processed by inverse distance weighting interpolation algorithm, the MSWEP’s monitoring results were more consistent with the actual drought regime. In general, compared with CHIRPS and PERSIANN-CDR, MSWEP had higher accuracies and greater drought monitoring potential in the Huaihe River Basin. The comparison and evaluation results of the accuracy and drought monitoring potential of quantitative precipitation products presented here can provide a basis for the application of products’ precipitation data for meteorological and agricultural drought monitoring.

In clinical practice, medullary hemorrhage is very rare in intracerebral hemorrhage, and literature often presents it in the form of case reports. Bilateral medial medullary hemorrhage is even rarer. This paper presents a case of an elderly male patient with a long history of hypertension and poorly controlled blood pressure. This time, the patient developed an acute onset of “dizziness, headache accompanied by nausea, vomiting”, and later developed symptoms such as difficulty in swallowing, dysphagia, aphasia, quadriplegia. Cranial CT scan showed a high density area on both sides of the medulla oblongata with a “heart” shape, diagnosed as medullary hemorrhage, and it was considered that this onset is related to hypertension. The full text first introduces the diagnosis and treatment process of the patient, and then discusses the etiology, clinical manifestations, auxiliary examinations, treatment and outcome, aiming to increase clinical experience of clinicians in diagnosis and treatment of this disease.
