    Abstract: A series of neutron absorbing materials with good neutron absorbing capacity, high strength and good thermal property were designed and prepared in this work. First of all, polyphenylene sulfide containing different mole content of salicylic acid (SAPPS) in the main chain was synthesized by nucleophilic substitution polymerization under high pressure. Then the composites with different content of nano Gd 2 O 3 and modified PPS were prepared by melt blending method. The testing results indicated that the copolymers SAPPS were synthesized successfully, there was an interface interaction between nano Gd 2 O 3 and the matrix without the need for surfactants or coupling agents. Additionally, the content of nano Gd 2 O 3 had no obvious influence on the thermal property of the composites. While following with the increase of the content of nano Gd 2 O 3 , the tensile strength of the composites increased firstly and then decreased, when the content of nano Gd 2 O 3 was 10 wt%, the tensile strength of 10%Gd 2 O 3 /5%SAPPS reached the maximum value of 74.9 MPa. The results of neutron shielding testing indicated that the content of nano-particles had a large effect on the neutron shielding rate of composites. The neutron shielding rate of 50%Gd 2 O 3 /5%SAPPS composite was up to 83%. All of these results indicated that the Gd 2 O 3 /5%SAPPS had potential to be applied to the high-temperature resistance and thermal shielding materials in nuclear and aerospace applications.

    SAGE Publications ; 2023

    Abstract: As representative underactuated and nonlinear systems, tower crane involves the multi-direction movement of the payload and even shows a more complex double pendulum in many actual situations, which makes the control problem more complicated. Most anti-swing controllers are mainly based on the linear design of tower crane dynamics at present and are insensitive to the position far from the equilibrium point. The time-varying cable length and double-pendulum effect are not taken into account simultaneously. Aiming at the problem of anti-swing control, a dynamic model of time-varying cable length tower crane with double-pendulum effect is established and an adaptive control method is proposed, which used the adaptive mutation strategy to update the mutation factor in real-time, and the parameters of the controller are tuned by an improved differential evolutionary algorithm. The simulations and experiments are carried out to verify the better optimization ability and faster convergence speed of the improved evolutionary algorithm in the process of parameter tuning and the effectiveness and superiority of the proposed control method are verified by comparing it with PID (proportion integration differentiation) and LQR (linear quadratic regulator) controllers.

    SAGE Publications ; 2015

    Abstract: K 2 Ti 6 O 13 nanowires are excellent inorganic nanomaterials, which have high value and huge potential use in many fields. However, the biocompatibility of K 2 Ti 6 O 13 nanowires will be directly related to its application. But the quantity of its hemocompatibility reports is limited. In this study, K 2 Ti 6 O 13 nanowires were first synthesized by sol–gel/hydrothermal combined method. In view of its biosafety, the hemocompatibility of the novel nanomaterial was investigated by a hemolysis test. Fresh whole blood was drawn by venipuncture from a healthy human volunteer. The absorbance of free hemoglobin in the clear supernatant of the blood mixtures in contact with the test, positive and negative control groups was measured by ultraviolet–visible spectrophotometer for evaluating the hemolysis ratio. The hemolysis ratio of the test group is far lower than the standard of 5%. And the results indicate that the novel material has no hemolytic effect and has application prospects in the fields of biomedicine and biomaterials.

    Early Effects of Low Dose 12 C 6+ Ion or X-Ray Irradiation on Peripheral Blood Lymphocytes of Patients with Alimentary Tract Cancer

    Abstract: The aim of this study was to examine the early effects of low dose 12 C 6+ irradiation or X-ray on peripheral blood lymphocytes (PBL) of patients with alimentary tract cancer and to explore mechanisms that may be involved in an antitumor immune response. We found that the percentage of T lymphocyte subsets, the mRNA expression levels of IL-2 and IFN-γ in PBL, and their protein levels in supernatant were significantly increased 24 hours after exposure to low dose radiation. The effects were more pronounced in the group receiving 0.05Gy 12 C 6+ ion irradiation than the group receiving X-ray irradiation. There was no significant change in the percentage of NK cell subsets and TNF-α production of PBL. Our study suggests that low dose irradiation could alleviate immune suppression caused by tumor burden and that the effect was more pronounced for 0.05Gy high linear energy transfer (LET) 12 C 6+ irradiation.

    SAGE Publications ; 2018

    Abstract: An autonomous underwater vehicle is able to conduct coverage detections, such as sea terrain mapping and submerged objects detection, using sonar. This work addresses the task of both optimizing and following routes that present a ladder shape. First, a planning method to determine a nearly optimal coverage route is designed. The track spacing is optimized considering the seabed type and the sonar range for the purpose of increasing detection probability. It also adds adaptability to confined water, such as harbors, by decomposing the geometrically concave mission region during the processing of the environmental data. Next, a decoupled and two-layered structure is adopted to design the following controller. The route is followed in the form of sequenced-lines tracking. A proportion–integral–derivative algorithm with fuzzy parameters adjustment is employed to calculate a reference heading angle according to the transverse position deviation in designing the guidance controller. An adaptive nonlinear S-surface law is adopted to design the yaw control. The route following the method is demonstrated with sonar (including side scanning sonar and multi-beam echo sounder) imagery collected in terrain mapping and object detection through sea trials.

    A New Immunomodulatory Therapy for Severe Sepsis: Ulinastatin Plus Thymosin α 1
    SAGE Publications ; 2009

    In: Journal of Intensive Care Medicine, SAGE Publications, Vol. 24, No. 1 ( 2009-01), p. 47-53
    Abstract: Objectives: To study the effect of immunomodulatory therapy with ulinastatin plus thymosin α 1 on septic patients. Method: A total of 56 sepsis patients were randomized into a treatment group, receiving immunomodulatory therapy, and a placebo group, a placebo. Acute Physiology and Chronic Health Evaluation II scores, clinical data, lymphocyte subsets, immunological indexes, and coagulation parameters were determined before admission and on the 3rd, 8th, and 28th day after admission to the Intensive Care Unit. Results: The treatment group experienced a 78% cumulative survival, the placebo group experienced a 60% cumulative survival; the survival difference was mirrored by Acute Physiology and Chronic Health Evaluation II scores and more quickly improved leukocyte counts, lymphocyte counts, coagulation parameters, and cytokine levels in the treatment. Conclusions: Combined immunomodulatory therapy with ulinastatin plus thymosin α 1 appears to yield improved survival for patients with sepsis; this finding should be verified in larger clinical trials.
