“…In food industry, Maltol is a synthetic flavor enhancer that can be added to beverages, baked food, ice creams and candies to enhance or change the inherent flavors of foods and beverages. However, eating excessive maltol can harm he kidneys and neuronal system (Zhang et al, 2018;Kniat, 2018;Shen et al, 2017).…”

Euphorbia tirucalli L. is an evergreen succulent shrub that possess ecological value because it can prevent water-soil loss, and it is also an energy plant of economic value. This study was carried out to evaluate the bio active constituents and bio drugs from the stem of Euphorbia tirucalli. Four techniques were analyzed for estimating the chemical components of E. tirucalli. Fourier Transform Infrared Spectroscopy (FT-IR), Gas Chromatography-Mass Spectrometry (GC-MS), Pyrolysis-Gas Chromatography-Mass Spectrometry (GC-MS), and thermogravimetric (TG) technologies were carried out to detect and analyze the chemical composition from the stem of Euphorbia tirucalli. Gas chromatography-mass spectrometry and pyrolysis-gas chromatography-mass spectrometry included β-lactose; 1-O-heptylhexitol; 3,5-dihydroxy-6-methyl-2,3-dihydro-4H-pyran-4-one; γ-sitosterol; 2ethylhexanol; vitamin E; dl-alanine; hydroxyacetone; syringol;and 1,2,4-cyclopentanetrione as the main chemical constituents of E. tirucalli stem. These constituents can be applied in food, medicine and industrial manufacturing.

“…Wei Rui analyzed the influence of natural cracks or joint shear slip on the conductivity of fractures [9]. Anderson, Renshaw, Peng, Cheng, and other domestic and foreign scholars also theoretically analyzed the occurrence conditions of natural fracture shear failure [10][11][12][13][14][15][16][17][18][19][20][21][22].…”

a b s t r a c tBedding fracture is the main rock mass of the tight reservoir; the main method for the formation of complex fractures of dense rock is to activate weak bedding to induce the branch extension of hydraulic fracture. Based on fracture mechanics, this paper established the mechanical model of coupled extension with weak bedding when the hydraulic fracture is close to the weak bedding process, adopted the numerical analysis method, based on the equivalent principle of coupling, through unit compilation techniques, and realized the numerical simulation of the expansion of hydraulic fracture and weak bedding. The results show that the hydraulic fracture tip passivation is induced by shear slip of weak bedding plane; the increase of shear stress in the weak bedding is the main control mechanism of the expansion of hydraulic fracture; the closer the approaching angle, the greater the elastic modulus of reservoir, and the lower the stress difference, the more difficult it is to induce weak bedding shear damage. The greater the viscosity of the fracturing fluid, the greater the displacement, the more prone to inducing shear damage of weak bedding plane, and the more complex the formation of cracks.

The upstream of Minjiang River, which was one of the main water sources for Chengdu Plain and the Yangtze River, was selected as the study area in the paper. With a series of cloud-free Landsat TM/OLI images acquired on June 24, 1994 and June 1, 2014, the vegetation coverage of the study area was calculated based on the vegetation index and dimidiate pixel model. The temporal and spatial changes of vegetation coverage were analyzed with digital elevation model and county area. The average vegetation coverage of the study area was decreased from 68.97% in 1994 to 60.39% in 2014. The analysis results showed that vegetation changes were closely related to topographical characteristics. The proportion of vegetation degradation area increased with the elevation increase and vegetation degradation was the most serious at the elevation range from 3500 m to 4500 m. The vegetation degeneration was the most obvious in Wenchuan County and Songpan County. Geological hazards caused by the earthquake and human disturbance were the main cause of the vegetation degradation and the aridity trend in the study area was another important factor.
