Frontiers in Energy 2007, Volume 1, Issue 1,   Pages 79-84 doi: 10.1007/s11708-007-0007-9

Abstract: Molecular-beam sampling mass spectrometry (MBMS) combined with tunable synchrotron radiation photoionization technique offers obvious advantages for the study of flame chemistry over other techniques because of the precision measurement of the combustion intermediates and products in flame. In this paper, the results to identify combustion intermediates in low-pressure premixed gasoline/oxygen flame with the synchrotron radiation were reported. Based on the results obtained, the formation process of five products and the difference between gasoline/oxygen and MTBE/gasoline/oxygen flame were emphatically analyzed. The results achieved provide data basis for the analysis of intermediates and radicals in flame, and are helpful to establish the kinetic modeling of gasoline/oxygen and MTBE/gasoline/oxygen flames.

Efficient controller area network data compression for automobile applications

Yu-jing WU,Jin-Gyun CHUNG

Frontiers of Information Technology & Electronic Engineering 2015, Volume 16, Issue 1,   Pages 70-78 doi: 10.1631/FITEE.1400136

Abstract: Controller area networks (CANs) have been designed for multiplexing communication between electronic control units (ECUs) in vehicles and many high-level industrial control applications. When a CAN bus is overloaded by a large number of ECUs connected to it, both the waiting time and the error probability of the data transmission are increased. Thus, it is desirable to reduce the CAN frame length, since the duration of data transmission is proportional to the frame length. In this paper, we present a CAN message compression method to reduce the CAN frame length. Experimental results indicate that CAN transmission data can be compressed by up to 81.06% with the proposed method. By using an embedded test board, we show that 64-bit engine management system (EMS) CAN data compression can be performed within 0.16 ms; consequently, the proposed algorithm can be successfully used in automobile applications.

Effect of UAV prewetting application during the flowering period of cotton on pesticide droplet deposition

Weixiang YAO, Xianju WANG, Yubin LAN, Ji JIN

Frontiers of Agricultural Science and Engineering 2018, Volume 5, Issue 4,   Pages 455-461 doi: 10.15302/J-FASE-2018232

Abstract:

Prewetting process can reduce the contact angle between the droplet and the leaf blade, so that the droplet can more easily wet and spread, thereby increasing the quantity of deposition. To improve the effectiveness of pesticides on cotton leaves, prewetting by single-rotor electric unmanned aerial vehicles (UAV) was studied, focusing on the effects of pesticide deposition on cotton leaves during the flowering period. Cotton leaves in 0°–30°, 30°–60°, 60°–90° leaf blade angle ranges (angle between the leaf blade and the horizontal plane) were examined. In the first experiment, four different prewetting volumes (0, 1.6, 3.2 and 4.8 L) were sprayed by a single-rotor electric UAV on four cotton plots (plots A to D) each with an area of 120 m , and then each area was sprayed with a 0.8% (w/v) ponceau 2R solution by another single-rotor electric UAV. The results revealed that with no prewetting, droplet deposition quantity decreased with increasing leaf blade inclination. After prewetting, the mean droplet deposition quantity on plots B, C and D increased by 39.8%, 9.7% and 24.9%, respectively. The prewetting rate of 1.6 L per 120 m had the most significant effect on improving the deposition of droplets. It was also found that the mean droplet deposition quantity in each leaf blade angle range increased after prewetting. For the leaf blade angle range 60° to 90°, this increase was the most pronounced, with 0.043, 0.062, 0.057 and 0.048 L·cm in plots A–D, respectively. Also, droplet deposition uniformity in the leaf blade angle range 60°–90° was better after prewetting. These results should provide a valuable reference for future research and practice to improve the effectiveness of pesticides applied to cotton by aerial applications.

Spatial distribution of phosphorus forms in sediments with different distances to the estuary of the Dianchi Lake, China

Shaoyong LU, Xiangcan JIN, Fengchang WU, Jing SI, Jianning GUO,

Frontiers of Environmental Science & Engineering 2010, Volume 4, Issue 3,   Pages 295-300 doi: 10.1007/s11783-010-0231-0

Abstract: Effects of human activity on the distribution of phosphorus (P) forms were investigated for the sediments and porewaters in Daqinghe Estuary of Dianchi Lake, China. The concentrations of total P (TP), inorganic-P (I-P), and organic-P (Org-P), and the ratio of iron-bound P (Fe-P)/calcium-bound P (Ca-P) in the sediments decreased with the increasing distance from the sampling site to the estuary. This is probably due to the flocculant materials, e.g., ferric and aluminous salts, usually being added in the wastewater treatment processes. The concentration of ammonia in the sediment porewaters significantly decreased with the increasing distance from the sampling site to the estuary. Both concentrations of total nitrogen and nitrogen in the sediment porewaters decreased to some content with the increasing distance from the sampling site to the estuary. However, the concentrations of nitrate, dissolved total P (DTP), and TP did not have strong relationship with the distances from the sampling sites to the estuary. Pollution load and water quantity also had an important influence on the concentrations of P in sediments and its interstitial water in estuary sedimentary area.

Chemical additives affect sulfate reducing bacteria biofilm properties adsorbed on stainless steel 316L surface in circulating cooling water system

Yu Qi,Jin Li,Rui Liang,Sitong Ji,Jianxiang Li,Meng Liu

Frontiers of Environmental Science & Engineering 2017, Volume 11, Issue 2, doi: 10.1007/s11783-017-0917-7

Abstract: There are more polysaccharides than proteins in EPS on SS316L surface. NaClO cuts down more protein, while 1227 reduced more polysaccharides in EPS. HEDP slightly eased the corrosion, NaClO and 1227 inhibited the microbial corrosion. NaClO still performed pitting corrosion properties to some extent. 1227 changed the C:O and NaClO decreased the amidogen in SS316L surface film. This paper studied the biofilm properties and corrosion behavior of sulfate reducing bacteria (SRB) on stainless steel 316L (SS316L) surface in circulating cooling water system with and without additives including hydroxy ethyl fork phosphonic acid (HEDP), dodecyl dimethyl benzyl ammonium chlotide (1227) and NaClO. Biochemical technique, electrochemical technology, X-ray photoelectron spectroscopy (XPS) and scanning electron microscope (SEM) were used. The results show that the extracellular polymeric substance (EPS) in biofilm attached on the SS316L surface mainly contain proteins and polysaccharides, the contents are 98 ug·cm and 635ug·cm , respectively. The polysaccharides were cut by 1227 about 80%, while 55% by NaClO. The proteins were reduced by NaClO about 53%, while only 30% by 1227. The potentiodynamic polarization shows that the corrosion potential of SS316L was enhanced from −0.495 V to −0.390 V by the chemical additives, delaying the occurrence of the corrosion. And the corrosion rate was also reduced from 5.19 × 10 mm·a to 2.42 × 10 mm·a . But NaClO still caused pitting corrosion after sterilizing the bacteria, while 1227 can form a protective film on the surface of SS316L. Though HEDP contribute to the bacteria activity, it can enhance the breakdown potential. XPS results confirmed that 1227 can change the value of C:O in the biofilm attached on metal surface, and NaClO can eliminate the existence of amidogen. This study would provide some recommendations for the selection of chemical additives in the thermal power plant.

Real-time pre-processing system with hardware accelerator for mobile core networks Article

Mian CHENG, Jin-shu SU, Jing XU

Frontiers of Information Technology & Electronic Engineering 2017, Volume 18, Issue 11,   Pages 1720-1731 doi: 10.1631/FITEE.1700507

Abstract: With the rapidly increasing number of mobile devices being used as essential terminals or platforms for communication, security threats now target the whole telecommunication infrastructure and become increasingly serious. Network probing tools, which are deployed as a bypass device at a mobile core network gateway, can collect and analyze all the traffic for security detection. However, due to the ever-increasing link speed, it is of vital importance to offload the processing pressure of the detection system. In this paper, we design and evaluate a real-time pre-processing system, which includes a hardware accelerator and a multi-core processor. The implemented prototype can quickly restore each encapsulated packet and effectively distribute traffic to multiple back-end detection systems. We demonstrate the prototype in a well-deployed network environment with large volumes of real data. Experimental results show that our system can achieve at least 18 Gb/s with no packet loss with all kinds of communication protocols.

Frontiers of Medicine 2007, Volume 1, Issue 3,   Pages 327-332 doi: 10.1007/s11684-007-0063-x

Abstract: Selenium compounds, as an effective chemopreventive agent, can induce apoptosis in tumor cells. Reactive oxygen species (ROS) are important mediators in apoptosis induced by various stimuli, which include chemopreventive agents. In this study, we investigated the relationship between ROS and the levels of DNA damage induced by selenite in HepG2 cells. After HepG2 cells were treated with selenite, there was a dose-dependent decrease in cell viability. The levels of ROS induced by selenite were measured by 2′, 7′-dichlorofluorescein diacetate (DCFH-DA) fluorescence, which shows a dose- and time-dependent increase in HepG2 cells. The levels of DNA damage in HepG2 increased in all cells treated with an increasing dose of selenite at 0, 2.5, 5, 10, and 20 μmol/L. N-acetylcysteine (NAC), a known antioxidant, increased cell viability and decreased ROS generation. Moreover, NAC effectively blocked DNA damage induced by selenite. These results revealed that ROS might play an important role in selenite-induced DNA damage that can be reduced by NAC treatment.

Abstract: Nowadays, pyogenic liver abscess (PLA) is still a common and severe intra-abdominal infection, and had emerged as the most common pathogenic bacteria worldwide in the past ten years. Our study aims to achieve an early pathogenic diagnosis and rational therapy modality for liver abscess (KLA) through clinical data analysis. A total of 197 inpatients in Zhongshan Hospital, Shanghai, diagnosed as having liver abscess between March 2001 and September 2009 were enrolled. Patients with monomicrobial infection were divided into two groups: patients with liver abscess (KLA group, =106) and those with non- liver abscess (NKLA group, =56). A retrospective analysis was made between these two groups on the aspects of underlying diseases, clinical characteristics, laboratory data, culture results, and imaging findings. To evaluate the effects of different medical interventions, monomicrobial KLA patients were further divided into four subgroups (percutaneous liver aspiration, aspiration plus antibiotics flushing, aspiration plus retained catheter, and aspiration plus antibiotics flushing and retained catheter), and corresponding therapeutic effects were analyzed. KLA was more likely to occur in patients with coexisting diseases such as diabetes mellitus (53.77% 25.00%, =0.001) and hepatic adipose infiltration (16.04% 5.36%, =0.029). Compared to NKLA group, clinical characteristics including abdominal pain (40.57% 57.14%, =0.044), hypodynamia (19.81% 46.43%, =0.001), and hepatomegaly (4.72% 14.29%, =0.033) were much milder, but with a higher fasting blood glucose level (7.84?±?0.36 5.76?±?0.30, =0.001) on admission in KLA group. In addition, KLA abscess often appeared singly in the right lobe of the liver with gas forming nature (32.88% 13.51%, =0.039), unsmooth rim (71.23% 40.54%, =0.002), and dynamic septum enhancement (41.10% 16.22%, =0.009). Compared to mono aspiration subgroup, additional antibiotic flushing could not further improve clinical outcomes of KLA patients ( >0.05); however, the retained catheter showed obvious advantage in reducing abscess diameter (34.38?±?3.25 mm 22.67?±?2.37 mm, =0.017). It can be concluded that the strong association with diabetes, milder clinical symptoms, and gas-forming nature in CT images makes early pathogenic diagnosis of KLA possible. Comparatively, ultrasonography-guided percutaneous liver aspiration with retained catheter may be the most rational intervention modality of KLA.
