        Removal of sulfur element from high-sulfur coal by superconducting HGMS technology

        Shuai-shuai,Han,Su-qin,Li,Rui-ming,Yang,Chang-qiao,Yang,Yi,Xing 한국초전도.저온공학회 2019 한국초전도저온공학회논문지 Vol.21 No.2

        Coal is the most abundant fossil fuel on Earth and is used in a wide range of applications. The direct combustion of high-sulfur coal produces a large amount of sulfur dioxide, which is a toxic and corrosive gas. A new superconducting high gradient magnetic separation (HGMS) technology was studied to remove sulfur from high sulfur coal. The magnetic separation concentrate was obtained under the optimum parameters, such as a particle size of -200 mesh, a magnetic field strength of 2.0 T, a slurry concentration of 15 g/L, and a slurry flow rate of 600 ml/min. The removal rate of sulfur is up to 59.9%. The method uses a magnetic field to remove sulfur-containing magnetic material from a pulverized coal solution. It is simple process with, high efficiency, and is a new way.

        A Stiffness Modeling Approach for Multi-Leaf Spring Mechanism Supporting Coupling Error Analysis of Nano- Stages

        Shuai-Shuai,Lu,Peng,Yan 한국정밀공학회 2017 International Journal of Precision Engineering and Vol.18 No.6

        In the present paper, we take the multi-leaf spring mechanism as a particular element to develop a modeling approach for the stiffness by considering the coupling effects of the cross axis force. With this, a more accurate model of the multi-leaf spring based nano-stage is derived by incorporating the effect of cross axis input force, which can better predict the coupling error. The new analytical model indicates that the total axial stiffness is an inverse-quadratic function of the cross axis input load instead of a constant value, which can be used to analyze the cross axis coupling error of multi-leaf spring based nano-stages. The proposed analysis method is then verified by FEA and experiments, where excellent results are demonstrated in predicting the cross axis coupling effects of nano-stages such as stiffness variation and coupling error. The proposed approach offers a new look into the design and manipulation of multileaf spring based nano-stages.

        Effects of aflatoxin B1 combined with ochratoxin A and/or zearalenone on metabolism, immune function, and antioxidant status in lactating dairy goats

        Shuai,Huang,Nan,Zheng,Caiyun,Fan,Ming,Cheng,Shang,Wang,Adil,Jabar,Jiaqi,Wang,Jianbo,Cheng 아세아·태평양축산학회 2018 Animal Bioscience Vol.31 No.4

        Objective: This experiment investigated the effects of aflatoxin B1 (AFB1) alone or mixed with ochratoxin A (OTA) and/or zearalenone (ZEA) on the metabolism, immune function, and antioxidant status of dairy goats. Methods: Fifty lactating Laoshan dairy goats were randomly assigned to one of five treatment groups (n = 10) for 14 days. Goats were fed no additive (control) or administered with 50 μg AFB1/kg dry matter (DM) (AFB1), 50 μg AFB1/kg DM+100 μg OTA/kg DM (AFB1+ OTA), 50 μg AFB1/kg DM+500 μg ZEA/kg DM (AFB1+ZEA), or 50 μg AFB1/kg DM+100 μg OTA/kg DM+500 μg ZEA/kg DM (AFB1+OTA+ZEA). Results: Dry matter intake and milk production were lower in goats fed AFB1+OTA+ZEA than in controls. Supplementation with AFB1, OTA, and ZEA significantly decreased red blood cell count, hematocrit, mean corpuscular volume, mean corpuscular hemoglobin, and mean platelet volume, and significantly increased white blood cell count, when compared with the control group. Compared with control, the combination of AFB1, OTA, and ZEA significantly increased alanine aminotransferase (ALT) and alkaline phosphatase (ALP) activities, total bilirubin (TBIL), interleukin-6, and malondialdehyde (MDA), but significantly reduced immunoglobulin A concentration, the activities of superoxide dismutase (SOD) and glutathione peroxides (GSH-Px), and total antioxidant capacity (T-AOC) in serum. Administration of AFB1 combined with OTA led to higher ALP, ALT, TBIL, and MDA, as well as lower milk production, SOD and GSH-Px activities, and T-AOC, than administration of AFB1 combined with ZEA. Conclusion: The mixture of AFB1, OTA, and ZEA exerted the greatest adverse effects on dairy goats, meanwhile the deleterious damage of the other mycotoxin combinations were in varying degrees. The findings of this study could provide guidance for the prevention and treatment of the consequences of contamination of animal feeds with combinations of mycotoxin.

        Integrated Optimization Design of Carbon Fiber Composite Framework for Small Lightweight Space Camera

        Shuai,Yang,Wei,Sha,Changzheng,Chen,Xingxiang,Zhang,Jianyue,Ren 한국광학회 2016 Journal of the optical society of Korea Vol.20 No.3

        A Carbon Fiber Composite (CFC) framework was designed for a small lightweight space camera. According to the distribution characteristics of each optical element in the optical system, CFC (M40J)was chosen to accomplish the design of the framework. TC4 embedded parts were used to solve the lowaccuracy of the CFC framework interface problem. An integrated optimization method and the optimizationstrategy which combined a genetic global optimization algorithm with a downhill simplex local optimizationalgorithm were adopted to optimize the structure parameters of the framework. After optimization, thetotal weight of the CFC framework and the TC4 embedded parts is 15.6 kg, accounting for only 18.4%that of the camera. The first order frequency of the camera reaches 104.8 Hz. Finally, a mechanicalenvironment test was performed, and the result demonstrates that the first order frequency of the camerais 102 Hz, which is consistent with the simulation result. It further verifies the rationality and correctnessof the optimization result. The integrated optimization method mentioned in this paper can be applied tothe structure design of other space cameras, which can greatly improve the structure design efficiency.

        Using Huff Model for Predicting the Potential Chiness Retail Market

        Shuai,Su,Myoung-Kil,Youn 한국유통과학회 2011 The Journal of Business, Economics, and Environme Vol.1 No.1

        This study aimed to predict retail sales of local markets in Jinan city of China with the Huff model. Using the Huff Model, we examined whether the predicted retail sales of local markets may be different in Jinan, China, from the department stores, supermarkets, shopping centers/shopping malls, and home appliance stores. The probability that a customer shops at location depends upon the store size and the travel time factors calculated by the Huff Model. We found that the predictedretail sales of shopping malls have a greater value than others. People who live in a mid-sized city may have easier access to any stores within the city boundary than people in metropolitan areas. Therefore, people in a mid-sized city are more sensitive to store size, because a bigger store size means greater opportunities, incentivizing consumers to travel further to competing stores after passing by nearer, smaller stores. This study has some limitations. First, the data is somewhat restricted in that the subject stores do not represent all of the stores in Jinan. Second, we cannot compare the estimated market share of the stores and the actual sales data. It is further suggested in this study that more databases be developed throughout such East Asian countries as Korea and Japan and that a different parameter λ value in the Huff Model be utilized for mid-sized cities.
