    Abstract: Subtle fault zones are caused by the weak deformation generated in the sedimentary cover of a sag due to the influence of regional or local stress fields or basement faults. They are too subtle to be easily identified by conventional exploration methods and technologies and are thus usually ignored. Research results prove that there are two basement faults in the Jinhu sag referred to as the NE-and NW-trending basement faults. Parts of the NE-trending basement fault are intense enough to control sag formation and evolution (such as the faults in Yangcun and Shigang, etc. ). However, the NW-trending and the rest of the NE-trending basement faults show weak activity and exert little influence on sedimentary cover deformation. These faults merely yield some weakly-deformed trend zones in the sedimentary cover, such as small en-echelon faults, small faults intermittently distributed along fixed directions, buried alluvial fans, zonal or stringy oil-gas traps, or linear structures (such as local folds, narrow and deep half-grabens, etc. ). Apart from the two aforementioned types of subtle fault zones, intermittent and stringy NS-trending subtle fault zones are also induced by the EW-trending extrusion stress component in the sag generated by the regional dextral stress field. Keywords: Jinhu sag; basement faults; subtle fault zones; tectonic evolution; en-echelon; trap distribution

    Abstract: The signal to noise ration of air-coupled ultrasonic testing is very poor and there is long time pulse residue, so it need adopt appropriate signal processing method to enhancing the SNR of received signal. Factors, which affect the received signal in ultrasonic testing process, is analyzed, phase sensitivity detection technology is presented to process the received signal, and ultrasonic testing information can be acquired by the calculation of phase signal. The principle of super-heterodyne receiver and phase sensitivity detector is introduced; some problem which should be pay attention in ultrasonic testing process is explained. Based on the research result, air-coupled ultrasonic testing system with phase sensitivity detector is constituted. Experiment results of image testing on carbon fiber reinforced plastic plate indicated that, phase sensitivity detection technology can improved signal to noise ratio of system and testing effect in evidence.

    Abstract: The bulk nanocrystalline aluminum are fabricated by cryomilling and hot-press sintering. The internal friction (IF) and relative dynamic modulus measurements in the nanocrystalline aluminum (Al) have been made using a multifunction internal friction apparatus (MFIFA) at low frequencies (0.2-3.0 Hz) over the wide temperature ranges from room temperature to 450 °C, while continuously changing-temperature forced vibration measurement. In the temperature spectrums of IF during heating process and cooling process, a distinct IF peak is found. Corresponding to the IF peak, the relative dynamic modulus decreases rapidly. The peak temperature of the IF peak shifts towards higher temperature with increasing frequency, i.e., the IF peak seem due to the thermal activated relaxation process. The IF peak is a grain boundary IF peak, which is associated with the diffusive grain boundary of Al/Al. Its activation energy has been calculated to be 2.21±0.04×10 -19 J and the pre-exponential factor is 10 -14 s in IF measurements.

    In: Advanced Materials Research, Trans Tech Publications, Ltd., Vol. 724-725 ( 2013-8), p. 120-127
    Abstract: A new direct illuminated receiver (DIR) for Dish/Stirling system was introduced in this study. The new cavity receiver was designed to help avoid the ruptures of the heater-head result from nonuniformities of temperature distribution. A method was also proposed to optimize the design of DIR. Both the efficiency and the reliability were improved as using this method in the experiment. The power output of the electric generating system was increased by around 300W. The new DIR operates safely at 900°C-1000°C, and cannot be sensitive to a short-lived cloud.

    Biodegradation of Paracetamol by Aerobic Granules in a Sequencing Batch Reactor (SBR)

    Abstract: Aerobic granules efficient at degrading paracetamol as the sole carbon and energy resource were successfully developed in a sequencing batch reactor (SBR). Aerobic granules were first observed about 220 days after reactor start-up. The images SEM showed the aerobic granules typically consisted of coccus and bacillus. Meanwhile, the size distribution of aerobic granules was analyzed on day 200. The result indicated that the granules eventually grew to become the dominant form of biomass in the reactor. The granular sludge on day 80 and 200 degraded paracetamol completely in 48 h and 28 h, respectively, indicating that granulation contributed to paracetamol degradation. The specific paracetamol degradation rate was observed to increase with increasing paracetamol initial concentration from 500 to 5000 mg/L, peaked at 1200 mg-MTBE/g-VSS·h, and declined with further increases in MTBE concentration as substrate inhibition effects became significant. This study demonstrates that paracetamol can be effectively degraded by aerobic granules and gives insight into the microorganisms potentially involved in the process.

    In: Advanced Materials Research, Trans Tech Publications, Ltd., Vol. 524-527 ( 2012-5), p. 2037-2043
    Abstract: By means of Oxygen and Nitrogen Analyzer, Metallographic Examination, SLIME, SEM, EDS, etc, the cleanliness of ultra-low carbon steel first slab produced by LD-RH-CC, and the comparative analysis with the cleanliness of normal slab is studied. The results show that T[O] and [N] are obviously decreasing with the increasing of casting length. The micro-inclusions and large-inclusions are generally decreasing with the increasing of casting length. The micro-inclusions of the first slab are mainly from deoxidization products and reoxidation of liquid steel. And the sources of large-sized inclusions mainly are reoxidation of liquid steel, slag entrapment in mould or tundish and stuffing sand. The cleanliness of ultra-low carbon steel first slab is closed to those normal slabs at the length of 3.5m.

    Abstract: Cu/graphene nanosheets composites were fabricated at 800°C by the hot-pressing method using Cu and graphene as initial materials. Graphene content was 1 wt. %-5 wt. %. The fracture morphology and physical properties of the composites were investigated. It was found that the relative density increased with the increment of graphene content from 1 wt% to 5 wt. % with reaching its highest level (96.68%) at 5wt. %. The composites have the anisotropic property which is vertical to the direction of pressure is higher than parallel to the direction of pressure. With the increasing of graphene content, the thermal conductivity property and the electronic conductivity decrease first and then increase with the minimum thermal conductivity and electric conductivity at 3wt%~4wt%.

    Abstract: To investigate the propagate channel for implantable devices deep inside of a human body to receiver on-body or outside body, a 3D electromagnetic model of human body which including 85 kinds of different human tissues and organs, based on CT and MRI slices data take from living human males, was built. The in-body channel path gain in different distance for 2.5/3.5 GHz biomedical implants was investigated using electromagnetic (EM) simulator and its numerical sta-tistical model was presented. EM simulation and numerical computational results show that the dis-tance dependent path gain for inside body can be modeled by a modificatory classical power law function with root-mean-square error (RMSE) of 2.6 and 3.9 for 2.5 GHz and 3.5 GHz, respectively
