On azimuthal eigenwavenumbers associated with Laplace's tidal equations

Laplace's tidal equations for the case of an ocean of constant depth bounded by meridians were considered by two authors at a specific frequency as an eigenvalue problem in the azimuthal wavenumber. A finite spectrum of eigenwavenumbers was found. That eigenvalue problem is re-examined by means of asymptotic techniques and numerical integration of the governing equation of the problem. At low frequencies a formula connecting the frequency and the number of eigensolutions is established. It is shown that at a given frequency the spectrum of eigenwavenumbers is wider than that reported, but (for this type of solution) the meridional boundary conditions are satisfied approximately only for the case of very low frequencies.     

北山戈壁荒漠景观1∶5万地球化学测量方法研究

通过在西北北山地区进行剖面和面积性方法试验,研制出了一套适合于西北荒漠戈壁景观条件的地球化学测量方法,即包括样品布局、采样密度、样品介质、样品粒级以及不同类型的地球化学测量方法技术。试验结果证实,每平方千米采集>20目的沟谷粗碎屑介质样品,能够圈定出清晰的矿化异常,而且异常元素组合齐全,指示意义明确,较准确地反映了矿体或矿化体的形态和延伸方向。同时辅助采集植物———红莎样品和<80目细粒级样品(提供热释汞分析),可以提取掩埋矿化体的信息。     

Structuring subjectivities? Using Q methodology in human geography

This paper presents a critical and reflexive account of using Q methodology in human geography. Q methodology has a long pedigree in psychological, political and sociological research, but is only recently beginning to be used by human geographers. We discuss, in particular, the parts of the process(es) of Q methodology that are often glossed over in the literature, through reflecting on our learning in using Q within a project examining the use and production of environmental science by NGOs. We conclude that Q may be a useful supplement to existing methods in human geography, as long as it is used creatively and reflexively and with full awareness of its interpretative dimensions.
