International Journal of Mining science and Technology 2015年第3期25卷 459-464页

作者： sahu s.n. sahu A.K. Biswal s.K. Mineral Process.n. Department CSIR-Institute of Minerals and Materials Technology

In order to identify the mixing and segregation behaviors in a mineral process.n. operation, pres.n. study aimed on the hydrodynamics of solid–liquid fluidization. The study was carried out in a fluidization column with tapings at different height of the bed to collect the sample. The binary particles considered in this study are hematite(4800 kg/m3) and quartz(2600 kg/m3) at different size fractions in the range of average size 87×10^(-6)m to 400×10^(-6)m. It is observed that for various binary mixtures, both quartz and hematite particles share the equal composition by mass(50%) at a particular height of fluidized bed, referred as ‘‘locus point'' of mixing. study indicates that the mixing zone volume will increase for a continuous fluidized bed plant operation. It is observed that the number of locus points varies from 1 to 3 signifying their dependency on the size ratios of binary mixture. Whenever, the difference in terminal velocity between quartz and hematite particles approaches to zero, mixing is ***, the pres.n. study is extended to find the segregation index for the different size ratios of quartz and hematite particles. It is evident that depending on the size ratios, various regions such as complete segregation, partial mixing and complete mixing can be observed.

Effect of Gas Velocity on the Dust sediment Layer in the Coupled Field of Corona Plasma and Cyclone

引用

Plasma science and Technology 2006年第5期8卷 588-590页

作者：魏名山马朝臣李明华 DAnIsH s.n. school of Mechanical and Vehicular Engineering Beijing Institute of Technology Beijing 100081 China China north Vehicle Research Institute Beijing 100072 China

A dust sediment layer was found on the outer tube wall when the EsCP （electrostatic centrifugal precipitator） trapped diesel particulates or ganister s.n.. The Compton back scatter method was used to measure the sediment thickness during the experiment. The effect of the inlet gas velocity on the dust sediment layer was investigated. PIV （Particle Image Velocimetry） was used to measure the velocity field between the inner barb tube wall and the outer tube wail. Experiments showed that the thickness of the sediment increased with time, and the sediment layer at the lower end was much thicker than that at the upper end. The agglomeration on the outer tube wall could be removed when the inlet gas velocity was increased to a certain value.

Thermodynamic Aspects of nanostructured CoAl Intermetallic Compound during Mechanical Alloying

引用

Journal of Materials science & Technology 2011年第7期27卷 601-606页

作者： s.n. Hosseini T. Mousavi F. Karimzadeh M.H. Enayati Department of Materials Engineering Nanotechnology and Advanced Materials Institute Isfahan University of Technology84156-83111 Iran

The nanostructured CoAl intermetallic compound was produced by mechanical alloying （MA） of the Co50Al50 elemental powder mixture in a planetary high energy ball mill. The ordered B2-CoAl structure with the grain size of about 6 nm was formed via a gradual reaction after 10 h of MA. A thermodynamic analysis of the process was also done. The results showed that the intermetallic compound of CoAl had the minimum Gibbs free energy compared to solid solution and amorphous states indicating the initial MA product was the most stable phase in the Co-Al system which was changed to a partially disordered structure with a steady long-range order of 0.82 at further milling. This amount of disordering caused the enthalpy of final product to show an increase of about 5.1 kJ·mol-1. Calculation of enthalpy related to the triple defect formation revealed that the enthalpy required for Al anti-sites formation was about 3 times greater than that for Co anti-sites formation.

natural and human-induced decline and spatio-temporal differentiation of terrestrial water storage over the Lancang-Mekong River Basin

引用

Journal of Geographical sciences 2025年第1期35卷 112-138页

作者： CHEn Junxu WAnG Yuan ZHAO Zhifang FAn Yunjiang luo Xiaochuan YI Lu FEnG siqi YAnG Liang Emlyn Yunnan Key Laboratory of soil Erosion Prevention and Green Development Yunnan University International Joint Research Center for Karstology Yunnan University school of Engineering Westlake University Department of Geography Ludwig Maximilian University of Munich (LMU)

Due to water conflicts and allocation in the Lancang-Mekong River Bas.n.LMRB), the spatio-temporal differentiation of total water resources and the natural-human influence need to be clarified. This work investigated LMRB's terrestrial water storage anomaly(TWsA) and its spatio-temporal dynamics during 2002–2020. Considering the effects of natural factors and human activities, the respective contributions of climate variability and human activities to terrestrial water storage change(TWsC) were separated. Results showed that:(1) LMRB's TWsA decreased by 0.3158 cm/a.(2) TWsA showed a gradual increase in distribution from southwest of MRB to middle LMRB and from northeast of LRB to middle LMRB. TWsA positively changed in Myanmar while slightly changed in Laos and China. It negatively changed in Vietnam, Thailand and Cambodia.(3) TWsA components decreased in a descending order of soil moisture, groundwater and precipitation.(4) natural factors had a substantial and spatial differentiated influence on TWsA over the LMRB.(5) Climate variability contributed 79% of TWsC in the LMRB while human activities contributed 21% with an increas.n. impact after 2008. The TWsC of upstream bas.n.countries was found to be controlled by climate variability while Vietnam and Cambodia's TWsC has been controlled by human activities s.n.e 2012.

neurocircuit regeneration by extracellular matrix reprogramming

作者： shengzhang su Ian n.Levasseur Kimberly M.Alonge Department of Medicinal Chemistry University of WashingtonSeattleWAUSA Department of Chemistry University of WashingtonSeattleWAUSA Department of Medicine University of Washington Medicine Diabetes InstituteSeattleWAUSA

The brain's extracellular matrix(ECM),which is comprised of protein and glycosaminoglycan(GAG)scaffolds,constitutes 20%-40% of the human brain and is considered one of the largest influencers on brain cell functioning(soles et al.,2023).s.n.hesized by neural and glial cells,the brain's ECM regulates a myriad of homeostatic cellular processes,including neuronal plasticity and firing(Miyata et al.,2012),cation buffering(Moraws ki et al.,2015),and glia-neuron interactions(Anders.n.et al.,2016).Considering the diversity of functions,dynamic remodeling of the brain's ECM indicates that this understudied medium is an active participant in both normal physiology and neurological diseases.
