1Development of dynamic-mathematical model of hydraulic excavator显示文摘This work deals with analysis of dynamic behaviour of hydraulic excavator on the basis of developed dynamic-mathematical model.The mathematical model with maximum five degrees of freedom is extended by new generalized coordinate which represents rotation around transversal main central axis of inertia of undercarriage.The excavator is described by a system of six nonlinear,nonhomogenous differential equations of the second kind.Numerical analysis of the differential equations has been done for BTH-600 hydraulic excavator with moving mechanism with pneumatic wheels.Vujic Dragoljub Lazarevic Olgica Batinic Vojislav 2017Journal of Central South University2017,24,9:5
2添加凹凸棒黏土对生物质固体成型燃料抗结渣性的影响显示文摘针对当前生物质固体成型燃料抗结渣剂成本高、抗结渣效果差等实际问题,该研究采用凹土作为天然复合添加剂,制备了凹土添加量为0~7%的生物质固体成型燃料,并对其进行了工业分析及高位热值测定。燃烧生物质固体成型燃料获得灰样,采用高速相机采集灰样宏观形貌,采用扫描电镜(Scanning Electron Microscope,SEM)对灰样微观形貌进行分析。最后借助X荧光(X-ray Fluorescence,XRF)、X射线衍射(X-ray Diffraction,XRD)对生物质灰成分进行确定,以分析凹土抗结渣机理。结果表明,凹土添加量为3%以下时,热值下降速度较小,但灰分随凹土添加量增大而增加较快。由宏观形貌和微观形貌谱图发现,凹土可以极好地提升生物质固体成型燃料抗结渣性,这主要是因为添加凹土后,凹土改变了K的迁移途径,生成了更多KAlSiO_(4)、KAlSi_(2)O_(6)、Ca_(2)Mg(Si_(2)O_(7))等高熔点的复盐。该研究可为解决生物质固体成型燃料行业缺乏高效低成本抗结渣剂问题提供良好解决方案。李发达 李金平 王志峰 王金明 Vojislav Novakovic 2022农业工程学报2022,38,6:2
3寒冷地区空气源热泵辅助太阳能热水器供暖性能显示文摘为提高太阳能热水器供暖的稳定性并大幅降低空气源热泵供暖的成本,提出空气源热泵辅助太阳能真空管热水器供暖构想,在甘肃省兰州市七里河区魏岭乡绿化村搭建空气源热泵辅助太阳能热水器供暖试验系统,详细研究了晴天、阴天及多云3种典型工况下系统的集热效率、热泵性能系数、系统太阳能保证率和系统能效比等.研究结果表明,晴天、阴天及多云工况下太阳能集热器有效得热量分别为75.5、4.1和49.2 kW·h,集热效率分别为61.3%、26.6%、55.2%,太阳能热泵平均性能系数(COP)分别为3.6、3.4、3.6,空气源热泵平均COP分别为0、2.9、3.1,系统实际供热量分别为113.4、125.9和124.8 kW·h,系统耗电量分别为33.4、50.5和42.7 kW·h,系统太阳能保证率分别为66.6%、3.3%、39.4%,系统能效比分别为3.4,2.5,2.9.研究证明了太阳能真空管集热器-空气源热泵系统用于寒冷地区供暖的可行性,为寒冷地区供暖提供了一种新途径.李金平 董玉慧 李彩军 代静波 牛轶男 NOVAKOVIC Vojislav 2023上海交通大学学报2023,57,7:2
4Erythrocytic transglutaminase inhibition hemolysis at presentation of celiac disease显示文摘Celiac disease (CD) is a common autoimmune condition.Previously it was considered to be a rare childhood disorder,but is actually considered a relatively common condition,present at any age,which may have multiple complications and manifestations.Hematological disorders of the disease are not uncommon.Among these disorders,the most frequently reported are anemias as a result of iron deficiency,often associated with folate and/or B12 deficiency.Anemias caused by hemolysis are very rarely reported in celiac patients.An 11-year-old girl with a previous uneventful medical history presented with severe hemolytic anemia.Hemolysis was Coombs negative,accompanied by inappropriate low reticulocyte count,despite exaggerated bone marrow hyperplasia of the erythroid precursors which showed normal maturation.Serology for recent infections,including EpsteinBarr virus,parvovirus B19,cytomegalovirus and mycoplasma,were all negative.Levels of serum IgA,IgG and IgM,were all within normal ranges for age.Screeningfor anti-DNA,antinuclear,antineutrophil cytoplasmic,antimicrosomal,antithyroglobulin,and antimitochondrial antibodies and lupus anticoagulants,was negative.She was also negative for human immunodeficiency virus.Conventional therapy with corticosteroids and intravenous immunoglobulin failed.CD was serendipitously discovered upon screening for anti-tissue transglutaminase autoantibodies.The disease was confirmed by biopsy of the small intestine mucosa.The patient recovered with gluten-free diet.A unique case of CD is presented.CD should be serologically screened in each patient with Coombs negative 'immune'hemolytic anemia,particularly if accompanied by 'reticulocytopenia'.A new hemolytic mechanism and very speculative explanation for 'reticulocytopenia'are discussed.Petar Ivanovski Dimitrije Nikoli Nikola Dimitrijevi Ivan Ivanovski Vojislav Perii 2010World Journal of Gastroenterology2010,16,44:1
