A linear regression model (LRM) for groundwater chemistry in and around the Vaniyambadi industrial area, Tamil Nadu, India

Chinese Journal Of Geochemistry 2013年第1期32卷 19-26页

作者： Sajil Kumar p.J. davis Delson p. Vernon J.G. James E.J. Brandenburg Technical University Cottbus-03046 Germany ITALCONSULT Riyadh-11421 Saudi Arabia Budapest University of Technology and Economics (BME) Budapest-Pf. 91 H-152 Hungary Water Institute Karunya UniversityCoimbatore-641114 India

A linear regression model in conjunction with cluster analysis was applied to the groundwater quality parameters for the Vaniyambadi industrial area, Tamil Nadu, India. These physico-chemical parameters were collected from 25 wells by intensive groundwater sampling conducted during January 2010. All the major ions, ph and electrical conductivity were analyzed. The abundances of cations were in the order of Na hose of anions were in the order of Cl hCO3 pectively. This was in agreement with the water types, Na-Cl and Na-Ca-hCO3, determined by the piper plot. high concentrations of the ions Na, Cl and SO4 were recorded near the tanneries that operate within the study area. While the elevated concentrations of hCO3 and F were observed away from the tanneries. This peculiar hydrochemical behaviour suggests that the chemistry of water is predominantly influenced by tannery effluents and weathering of silicate minerals. Results of the linear regression model yielded 11 regression equations for the 5 most correlated parameters. A dendrogram from the cluster analysis showed 2 major clusters representing the influence of tanneries and geological formations in the study area, which confirmed the results of major ion chemistry.

实验在8只大棕蝠(Eptesicusfuscus)上进行。选取了5个声源方位 :记录部位对侧80°(C -80°)、40°(C -40°)、0°和同侧40°(I -40°)、80°(I -80°)。下丘听神经元的频率调谐曲线的形状有三种 :V型、封闭型和U型。以C -40°的频率调谐曲线为对照 ,声源方位改变时 ,多数神经元频率调谐曲线的形状和最佳频率不变。多数神经元在声源方位由记录部位对侧转向同侧时 ,频率调谐曲线的锐度 (以QndB 值为指标 )由小变大 ;神经元在I -80°、I -40°的QndB 值显著高于C -80°、C -40°、0°的QndB 值。在所观察的47个神经元中 ,5个声源方位的最低阈值的平均值有显著差异 ,由高到低的分布为 :MTI -80°>MTI -40°>MT0°>MTC -80°>MTC -40°。我们推测 ,声源方位对神经元频率调谐特性影响的机制,可能是抑制性和兴奋性输入的比例不同而相互整合的结果。

Sensor location in concrete slabs with various layout of opening using modified ‘FEMS-COMAC’ approach

Two-way concrete slabs are widely used around the world for the construction of many types of infrastructures and common buildings. The optimal sensor placement(OSp) in slabs with various opening positions is the most important issue in structural health monitoring(ShM) to increase reliability. In this study, a novel approach of OSp was evaluated to obtain the number and placement of sensors using examination of the closed loop performance. The nonlinear finite element(NFE) was used to discretize the mechanism behavior of slab. Multi-Objective Optimization based on the coordinate modal assurance criterion(COMAC) and cost considerations was considered in the optimization processes. All of the analysis, discretization and optimization process was designed and developed as a novel approach in Matlab by the author under the name ‘FEMS-COMAC’(FEM analysis of slab with COMAC). The points in the finite element method(FEM) mesh were classified as line by line information along the slab. The OSp in each line was optimized according to the objective function. The slabs with various width, thickness, aspect ratio and opening position were selected as case studies. The results of the OSp using the COMAC algorithm around the slab openings were compared with the novel ‘FEMS-COMAC’ method. The statistical analysis according Mann-Whitney criteria shows that there were significant differences between them in some of the case studies(mean p-value=0.54).

We discuss the bosonization of a relativistic very dense Fermi gas in a magnetic field and the consequent Bose-Einstein condensation of the resulting relativistic vector gas of charged particles. The model may be applied to paired spin-up electrons. We show that such systems may maintain self-consistently magnetic fields of order 10(10) - 10(13) G. That pairing could be the origin of large magnetic fields in some white dwarfs and neutron stars. For fields large enough (similar to10(13) for white dwarfs), the system becomes unstable and collapses.

INVESTIGATION OF ThE ATRp OF n-BUTYL METhACRYLATE USING ThE Cu(I)/N,N,N',N",N"-pENTAMEThYLDIEThYLENETRIAMINE CATALYST SYSTEM

引用

Chinese Journal of polymer Science 2004年第2期22卷 195-204页

作者： Kelly A. davis Krzysztof Matyjaszewski Center for Macromolecular Engineering Department of Chemistry Carnegie Mellon University 4400 Fifth Ave.Pittsburgh Pennsylvania 15213 USACenter for Macromolecular Engineering Department of Chemistry Carnegie Mellon University 4400 Fifth Ave.Pittsburgh Pennsylvania 15213 USA

The polymerization of n-butyl methacrylate was investigated using the Atom Transfer Radical polymerization technique with CuBr and CuCl/N,N,N',N',N'-pentamethyldiethylenetriamine catalytic systems. Various combinations of catalyst systems and initiators were utilized in order to optimize the polymerization conditions and to obtain well-defined polymers (i.e. controlled molecular weights and low polydispersities). It has been found that the optimal initiator for this system is a chlorine-based initiator, when the catalyst used is a salt in conjunction with the N,N,N',N',N'- pentamethyldiethylenetriamine ligand. Bromine-based initiators tend to result in large amounts of initial termination, leading to polymers with less than ideal chain end functionality, even if CuCl is used as the species to invoke the halogen exchange. Additionally, the effects of the polymerization temperature, species and the initiator structure were determined.
