The Benue Trough Basin (BTB) of Nigeria is geologically and geo-morphologically subdivided into upper,middle, and lower segments. The BTB is the subject of geological research due to its rich coal depositsthat have the potential for oil and gas. The purpose of the present study is to examine the origins,depositional environments, and thermal history of the selected coals and the processes that influencetheir quality. coal samples from different open cast coal mines in the middle BTB were examined usingproximate and ultimate, x-ray diffraction (XRD), x-ray fluorescence (XRF), laser ablation induced coupledplasma (LA-IcPMS), and petrographical analyses. The coal samples contained mainly quartz, kaolinite,and organic carbon. The XRD spectra peaks revealed the triclinic and monoclinic structure of kaolin. TheSiO2/Al2O3 ratios confirmed the dominance of quartz and kaolinite. The Ni/co versus V/cr, cu/Zn, and V/Mo values in the studied coals suggest oxic depositional environments, whereas the V/(Ni þ V) and V/(V þ cr) values indicate oxic to suboxic conditions. The ce/ce* values are slightly below 1, which indicates a suboxic depositional environment. Maceral texture is indicative of transformations from subbituminous to high volatile c or B bituminous coal. The maceral components and mineral matter(10%) of the studied coals imply deposition in the planar margin mire, and a river system of planarmargin mire environments, respectively. The high gelification index (GI) and tissue preservation index(TPI) values indicate peat accumulation developed within a wet forest swamp. The ternary diagram ofthe maceral component suggests deposition in a wet moor environment with intermittent moderate tohigh flooding episodes. The studied coals are sub-hydrous vitrinite inferring hydrogen-poor and thermally immature characteristics. The low V and Ni contents, low H/c and high O/c, indicate Type IIIterrestrial organic matter with the potential to generate gaseous hydrocarbons. The investi

AN AccURATE NUMERIcAL SOLUTION OF A TWO DIMENSIONAL HEAT TRANSFER PROBLEM WITH A PARABOLIc BOUNDARY LAYER

Journal of computational Mathematics 1998年第1期16卷 27-39页

作者： c.clavero J.J.H.Miller E.O'Riordan G.I.Shishkin Universidad de Zaragoza 西班牙 Trinity college 爱尔兰 Dublin city University 爱尔兰 Institute of Mathematics and Mechanics 俄罗斯

A singularly perturbed linear convection-diffusion problem for heat transfer in two dimensions with a parabolic boundary layer is solved numerically The numerical method consists of a special piecewise uniform mesh condensing in a neighbourhood of the parabolic layer and a standard finite difference operator satisfying a discrete maximum principle. The numerical computations demonstrate numerically that the method is epsilon-uniform in the sense that the Fate of convergence and error constant of the method are independent of the singular perturbation parameter epsilon. This means that no matter how small the singular perturbation parameter epsilon is, the numerical method produces solutions with guaranteed accuracy depending solely on the number of mesh points used.

通过比较磁纳米颗粒在体内的理想均匀分布和真实实验分布,研究了不同纳米流体分布对治疗温度的影响,其中真实分布来源于实验结果经本文所提出方法处理后的图像分布。同时,还进一步研究了纳米流体扩散行为对浓度分布的影响,以及研究了温度依赖性的血液灌注率和传统定值灌注率对治疗温度分布影响的差异。本研究基于热等效应剂量的角度,通过43℃下的累积等效分钟数来评估磁流体热疗的治疗效果,该方法与治疗温度分布直接相关。模拟结果表明,在考虑单个磁性纳米颗粒临界功率耗散的情况下,纳米流体扩散对肿瘤区域内纳米流体分布的均匀度具有积极的影响,而对最终治疗温度的影响则较小。
