Analysis of concentration patterns in volcanic rocks: Insights into dynamics of highly explosive volcanic eruptions

In this contribution we present new data resulting from the analysis of concentration patterns of mixed juvenile fragments ejected by a highly explosive volcanic eruption that occurred on Salina Island (Aeolian Islands, Italy) and our aim is to identify the fluid-dynamic regime characterizing the magma mixing process. Concentration patterns are studied by calculating the power spectrum of concentration variability along transects crossing the magma mixing structures. Results indicate that the slope of power spectrum has an average value of about −5/3, according to Kolmogorov law of turbulence, and suggest that the magma mixing process, in the studied conditions, can be approximated by considering the passive scalar mixing hypothesis in homogeneous isotropic turbulent flow. These results represent a first step towards a better understanding of magma mixing processes associated to highly explosive volcanic eruptions and this first step is taken by studying concentration patterns in volcanic rocks by coupling petrological and non-linear dynamics methods.

拉萨郊区藏族的跖纹研究

作者研究了拉萨郊区２５０例藏族的跖纹，结果如下：１．拇趾球纹依次为Ｌ〉Ｗ〉Ａ。２．趾间区真实花纹频率为Ⅲ〉Ⅱ〉Ⅳ。３．足小鱼际远侧区真实花纹较多，其他跖区较少。４．在性别、民族和人种间进行了比较，结果显示，藏族有自己的跖纹特点，又呈现蒙古人种的一般特征。     

玉米两个自交系及其杂交F_1染色体G-带带型的比较

对玉米两个自交系京7和华5及其杂交F_1的染色体G-带带型进行了比较研究。结果表明,两自交系的G-带中A型带之间的相似点很多,有的完全一致;而B型带在带的数目和分布位置上有差异。杂交F_1的G-带带型具有杂合性,B型带的杂合性尤为明显。文中讨论了G-带、C-带和N-带并存等问题。     

Closed solution to electromagnetic scattering of a plane wave by an eccentric cylinder coated with metamaterials

Closed series solution of electromagnetic scattering by an eccentric coated cylinder is achieved in matrix form. Diffracted field patterns are examined for an incident plane transverse magnetic (TM) wave. The solution is found by the classical separation of variables technique and the translational addition theorems. Wave transformation and orthogonality of the complex exponentials are employed to produce an infinite series. Numerical results are then shown by shortening the infinite series to a limited number of terms. Solutions are discussed for a dielectric or a metamaterial coating.
