On the whole biomass agriculture

SHI Yuanchun
Science & Technology Review. 2016, 34 (13): 11-14. ;  doi: 10.3981/j.issn.1000-7857.2016.13.001

Abstract ( 334 )
Based on the viewpoint of agricultural history, the author proposed a concept of "Whole Biomass Agriculture" that is contrary to the traditional agriculture whose biomass harvest only used by about half in forms of seeds, fruits, meets, eggs and milk, in the past thousands of years. In traditional agriculture, the residues and excretion of livestock are mere agro-wastes, on the contrary, modern bioconversion technologies could convert them and all available biomass into bioenergy and bio-based materials, and receives much value-add benefits. Such model of agriculture can tap new resources from wastes even pollutants through recycling process, and realize "winwin" results of substances reutilization and environmental protection. Bioenergy and bio-based materials are made from crop straw, livestock excretion, forestry residues, organic wastes of processing industry, MSW, as well as energy plants grown on marginal land. Such a "nonfood″ biomass system is of same nature of life process as common agriculture, with biological production and bioproducts as its system functions. It is then suggested that ″non-food″ biomass should be involved in modern agricultural production system, and promotes "Half Biomass Agriculture" or "Part Biomass Agriculture" into "Whole Biomass Agriculture" or "Biomass All-Used Agriculture". Five 'non-food' biomass industry chains and growth points that could be commercialization were also proposed in the paper.

Abstract ( 309 )
To study the affection of the H1N1 influenza virus activity by extract of Radix Isatidis herbs, Radix Isatidis granula and Radix Isatidis herbs active component. The chicken embryo was used for assaying the antiviral activities of Radix isatidis herbs and granula extracts as well as Radix isatidis herbs active component, by prevention, treatment, and virus neutralization. Radix isatidis herbs and granula extract had good inhibition on influenza virus activity. Radix isatidis herbs extract has the effect of prevention and neutralize against influenza virus; Radix isatidis granula extract and Radix isatidis herbs active component has the effect of neutralizing against influenza virus.

Numerical simulation of directional fracture blast in grooving borehole based on XFEM method

LI Qing, GUO Yang, ZHANG Leizhi, XU Wenlong, ZHANG Jiangyu, CHANG Xu
Science & Technology Review. 2016, 34 (13): 83-87. ;  doi: 10.3981/j.issn.1000-7857.2016.13.013

Abstract ( 197 )
The blast- induced crack initiation, propagation and arrest along both grooving and non- grooving directions in grooving directional fracture blasting are simulated by using the extended finite element method (XFEM) in the ABAQUS software. The results show that, it is 10 μs earlier in the grooving direction for the charge explosion to initiate cracks than in the non-grooving direction; while the crack propagation in the non-grooving direction does not see clear stages, the crack propagation in the grooving direction is clearly in three stages: the accelerating crack propagation, the unstable crack propagation and the decelerating crack propagation; the crack arrest time along the grooving direction is 60 μs more as compared with that in the non-grooving direction. During the crack propagation stage, the average speed of the unstable propagation in the grooving direction is 1343 m/s, while, it is 44% less in the non-grooving direction with the average speed of 600 m/s. This indicates that the groove is benecial for releasing the blast energy, and increasing the crack speed to a higher level. The groove has obviously the guidance effect in the extension direction of cracks, for the average crack length in the grooving and non-grooving directions is 124 mm and 45 mm, respectively. The XFEM method shows a promising prospect in simulating the crack propagation in the grooving directional blast.

Characteristics and formation mechanism of reservoir fractures in the west tip of Sinjar uplift

NING Fei, HE Juan, ZHAO Liangdong, CHANG Hongwei
Science & Technology Review. 2016, 34 (13): 88-92. ;  doi: 10.3981/j.issn.1000-7857.2016.13.014

Abstract ( 276 )
The development extent of fractures is a decisive factor that affects the productivity of a fractured reservoir. In order to better understand and reveal the development characteristic of a fractured reservoir, the characteristics and the formation mechanism of fractures in the west tip of Sinjar uplift are studied using the methods of structural analysis and correlation of structural elements based on 3D seismic and FMI data. The fractures are vertically stratified with anticlockwise- rotating strikes from lower to upper formations. The development of the fractures sees a close relationship with the reactivation of large faults developed in the underlying layers. The reactivated deep faults in the later stage are the strike-slip faults, and the strikes rotate anticlockwise while developing upward, which affects the orientation of new fractures developed on the top layer of the strike-slip faults. Due to the importance of fractures to carbonate reservoirs, and the close relationship between the shallow fractures and the deep-burying strike-slip faults, the intensity of fractures is decreasing upward from Jaddala formation to Chilou formation, and the areas with deep faults being developed shall be good prospecting places.

Abstract ( 326 )
Because lack of hypothesis of single factor in test of lab and exist high cost, hard-to-reduplicated and data "noise" in field experiment, one of the bottlenecks to limit the development of ecology is the suitable test method of ecological hypothesis' decisive experiment. This paper introduces the origin of test of ecological hypothesis, analysis function of test method of decisive experiment, demonstrates the test in lab and the theory, exercise and development of test method of field experiment of ecological hypothesis, and, discusses the operation criteria of ecological field experiment (coordinated distributed experiments, CDEs), proposed by Fraser et al (2013), and native case (CARE-China).
