| 1 | Preventative effect of massage on gastric volvulus in infants with gastroesophageal reflux-induced pneumonia显示文摘OBJECTIVE:To study the preventative effects of massage on gastric volvulus(GV) in infants with gastroesophageal reflux(GER)-induced pneumonia.METHODS:One-hundred and eighty GV with GER-induced pneumonia inpatients were divided randomly into four groups:basic treatment 1(n =60),basic treatment 2(n = 30),massage treatment1(n = 60) and massage treatment 2(n = 30).Clinical examinations selected between groups 1 and 2were different.Radiography of the upper gastrointestinal tract using iodine-containing contrast was assessed in group 1 before and after treatment,whereas 24-h pH monitoring of the distal esophagus was assessed in group 2 before and after treatment.Symptom scores and chest radiography were assessed in all groups upon hospital admission and after procedures.Clinical effects were estimated after procedures in all groups.The prevalence of severe pneumonia among the four groups was compared.RESULTS:Massage treatment groups showed a significantly higher percentage of cure and total effect(P<0.05,P<0.01) and a lower prevalence of recurrence(but with no statistic difference,P>0.05)than basic treatment groups.Furthermore,massage treatment groups had remarkably lower scores for symptoms and signs(P<0.05,P<0.01),especially for choking on milk,than basic treatment groups.There was significant attenuation of chest inflammation(P<0.05,P<0.01),GV(P<0.05,P<0.01) and GER(P<0.05,P<0.01) in massage treatment groups compared with those in basic treatment groups.Finally,massage treatment groups demonstrated a lower prevalence of severe pneumonia than basic treatment groups(P<0.05).CONCLUSION:Massage treatment can prevent GV with GER-induced pneumonia in infants by timely correction of stomach rotation and subsequent attenuation of GER. | Yan Suqi Xiong Xiaoli Wan Qi Liu Fan Tang Jianqiao Jiang Zhixia Zhou Lishan Yuan Kai Xie Dong | 2015 | Journal of Traditional Chinese Medicine2015，35，5： | 3 |
| 2 | Application of a Newly Built Semi-submersible Vessel for Transportation of a Tension Leg Platform显示文摘紧张腿站台(TLP ) 的交通组织因为长距离总是与一个重半运输容器的使用被联系了。这类容器的要求总是是特殊的,并且他们的可获得性是有限的。为华南海深海的工程的未来发展准备,中国近海油工程公司最近造了重电梯运输 vessel-Hai 杨实你 278。这个半能沉入水中的容器有 42 米的 50k DWT,和呼吸的一个排水量能力。理解容器适用性并且在未来为使用准备它深海的工程正在成为逼近的需要。这份报纸考察与 TLP 交通联系的当前的关键问题并且在装载外面和交通期间执行设计 TLP 的详细分析。新建 COOEC 交通容器 HYSY 278 被使用在华南在 Qingdao 从 COOEC 制造院子弄干 TLP 结构的运输到一块油地海。全部进程从制造院子,从容器,在长距离上的 TLP 的干燥运输,并且平台的最后的卸载卸载和平台的漂浮上的 landsite 包括了 TLP 结构的装载外面。水动力学和结构分析被执行评估运输容器和 TLP 结构的行为。特殊注意对与这个新容器的使用联系的批评区域被给予,与任何潜在的限制一起。结果证明 HYSY 278 能有效地被用于与合适的安排和准备得好的操作搬运结构。过程和细节根据学习结果被介绍。特殊注意也从分析基于结果被给未来使用的讨论。 | Dagang Zhang WeiyingSun Zhixia Fan | 2012 | Journal of Marine Science and Application2012，11，3： | 1 |
| 3 | Numerical Modeling of Local Scour Around Hydraulic Structure in Sandy Beds by Dynamic Mesh Method显示文摘Local scour, a non-negligible factor in hydraulic engineering, endangers the safety of hydraulic structures. In this work, a numerical model for simulating local scour was constructed, based on the open source code computational fluid dynamics model Open FOAM. We consider both the bedload and suspended load sediment transport in the scour model and adopt the dynamic mesh method to simulate the evolution of the bed elevation. We use the finite area method to project data between the three-dimensional flow model and the two-dimensional(2D) scour model. We also improved the 2D sand slide method and added it to the scour model to correct the bed bathymetry when the bed slope angle exceeds the angle of repose. Moreover, to validate our scour model, we conducted and compared the results of three experiments with those of the developed model. The validation results show that our developed model can reliably simulate local scour. | FAN Fei LIANG Bingchen BAI Yuchuan ZHU Zhixia ZHU Yanjun | 2017 | Journal of Ocean University of China2017，16，5： | 0 |
| 4 | Many-Objective Optimization-Based Task Scheduling in Hybrid Cloud Environments显示文摘Due to the security and scalability features of hybrid cloud architecture,it can bettermeet the diverse requirements of users for cloud services.And a reasonable resource allocation solution is the key to adequately utilize the hybrid cloud.However,most previous studies have not comprehensively optimized the performance of hybrid cloud task scheduling,even ignoring the conflicts between its security privacy features and other requirements.Based on the above problems,a many-objective hybrid cloud task scheduling optimization model(HCTSO)is constructed combining risk rate,resource utilization,total cost,and task completion time.Meanwhile,an opposition-based learning knee point-driven many-objective evolutionary algorithm(OBL-KnEA)is proposed to improve the performance of model solving.The algorithm uses opposition-based learning to generate initial populations for faster convergence.Furthermore,a perturbation-based multipoint crossover operator and a dynamic range mutation operator are designed to extend the search range.By comparing the experiments with other excellent algorithms on HCTSO,OBL-KnEA achieves excellent results in terms of evaluation metrics,initial populations,and model optimization effects. | Mengkai Zhao Zhixia Zhang Tian Fan Wanwan Guo Zhihua Cui | 2023 | Computer Modeling in Engineering & Sciences2023，，9： | 0 |
| 5 | Enhance hydrates formation with stainless steel fiber for high capacity methane storage显示文摘In order to realize efficient gas storage of hydrate,stainless steel fiber(SSF)was added to 0.03%(mass)sodium dodecyl sulfate(SDS)solution for gas storage experiment.SSF can not only improve the problem that hydration heat cannot be removed effectively in the hydration process,but also improve gas storage speed and gas storage by increasing hydrate nucleation sites.Under the experimental conditions(273.2 K,5-9 MPa),the peaks of temperature rise in SDS+SSF systems were found to become much smaller than those in SDS systems.The maximum gas storage rate and the maximum methane uptake of SSF+SDS system reached 9.89-24.90 cm^(3)·g^(-1)·min^(-1) and 178.65-200.89 cm^(3)·(g H_(2)O)-1,respectively.Compared with the surfactant SDS solution without SSF,they increased by 10.47%-33.22%and 9.16%-25.36%,respectively.The effect of SSF length on gas storage performance was studied.Due to the continuous thermal conduction network,longer SSF showed a higher gas storage capacity and methane uptake rate compared with shorter SSF.At the same time,compared with other metal fillers,SSF+SDS not only had excellent gas storage performance,but also the amount of SSF(0.1 g·ml^(-1))was only 7.6%of foamed aluminum,and the volume gas storage density was increased by 145.4%.The use of stainless steel fiber made the best use of the thermal conductivity of metal,reduced the amount of metal used,and improved the volume density and mass density of gas storage. | Zhixia Deng Shuanshi Fan Yanhong Wang Xuemei Lang Gang Li | 2022 | Chinese Journal of Chemical Engineering2022，，10： | 0 |
