Previous studies have shown that individuals responded preferentially to the mark of the top-scent donor relative to that of the bottom-scent donor of an over-mark. However, terrestrial mammals are likely to encounter over-marks consisting of the scent marks of more than two same-sex conspecifics in the intersections of runways, near the nests of sexually receptive female conspecifics, and inside and along the borders of the territories of conspecifics. We determined how meadow voles, Microtus pennsylvanicus, respond to the marks of the top-, middle-, and bottom-scent donors of an over-mark. We tested the hypothesis that voles exposed to an over-mark will respond preferentially to the scent marks that were deposited more recently, the scent marks that were on top or near the top of the over-mark, compared to the scent marks that were deposited earlier or near the bot- tom of the over-mark. Voles spent more time investigating the mark of the top-scent donor than that of the either the middle- or bottom-scent donor. However, males but not female voles spent more time investigating the middle-scent mark than the bot- tom-scent mark. We also tested the hypothesis that voles evaluate and respond to over-marks differently from single scent marks. Voles spent more time investigating the marks of the top-, middle-, and bottom-scent donors compared to scent marks that were not part of the over-mark. Voles can distinguish among the overlapping scent marks of three scent donors and sex differences exist in the values they appear to attach to each of these scent marks [current Zoology 57 （4）： 441-448, 2011 ].

The magnetic materials industry in Korea started from the production of the ferrite and alnico magnet at the end of 1970s. At that time, most electronic company in Korea imported the equipment parts and made them up. As one of electronic equipments, its development dropped behind other countries. In 1980s, with the revaluing upward of Japanese yen and the increment of the domestic need in Korea, several new magnet manufacturing plants were built up.

近年来,钼(Mo)元素有关的地球化学指标在刻画古海洋化学环境上发挥越来越重要的作用.本文系统介绍了Mo在海洋地球化学循环过程中的富集和同位素分馏基本原理及其在古海洋化学重建中的具体应用.综述表明:铁锰氧化物/氢氧化物的吸附和H2S的硫代作用是Mo在沉积物中富集的主要途径.因此,缺氧沉积物中Mo的富集通常反映了水柱和/或沉积物孔隙水中H2S的出现.硫化沉积物中Mo富集程度除与水柱或孔隙水中硫化程度有关外,还与海洋Mo库的大小有关.基于上述原理,对海洋硫化沉积物中Mo及Mo/TOc的地史演化重建表明:海洋Mo库演化与大气和海洋的演化历程具有很好的对应关系,表现出与地球两次大气-海洋氧化事件对应的阶段性演化特征.Mo同位素分馏原理及应用表明:强硫化沉积物可以有效记录沉积时海水的Mo同位素组成,而其他过程,包括锰铁氧化物/氢氧化物的吸附作用、低浓度H2S作用等均会导致沉积物不同程度富集轻Mo同位素.成岩作用可能会导致上述Mo富集和同位素分馏过程复杂化.在对沉积时海水的Mo同位素组成和不同水体环境下输出的Mo同位素组成进行必要约束的前提下,应用Mo同位素质量平衡模型可以对地质历史时期海洋总体的氧化还原状态进行定量重建.综上,Mo对局部和全球海洋的氧化还原状态变化敏感,可以有效应用于古海洋不同尺度的水体化学重建;但由于海洋化学过程的复杂性,在应用Mo地球化学指标进行古海洋化学重建时需要注意可能的多地球化学过程叠加的干扰.

The two three-dimensional oxo-bfidged lanthanides {[Ln2（c4H2O4）3（H20）4]· 3H2O}3, with Ln=Ho3＋（1）; Gd3＋（2）, are isomorphous. They have layer-type structures built up from non-centrosymrnetric dinuclear unit Ln2O12（H2O）4, beside three lattice H20 molecules stabilizing the 3D open-frmnework. The building entities are linked through one classical syn-anti g2-carboxylato-K1O：K^1O＇ bridge. Within the bi-polyhedra, two double μ2-O＇; K2O,O＇ bridges and a syn-syn classical one, support the magnetic measurements carried out on holmium compound indicating relatively weak anti-ferromagnetic interactions. The compari- son with magnetic studies on the almost similar reported Gd（III） compound, suggested that concomitant antiferromagnetic and ferro- magnetic properties could not be excluded. The two distinct thermal behaviors evidenced the higher metal-water bond strength with the smaller cation, and revealed the great supramolecular effects generated by hydrogen-bonding patterns.

Dislocation structures in polycrystalline Ni 3Al alloy doped with palladium deformed at room temperature have been investigated by transmission electron microscopy. The structure consists mainly of dislocations dissociated into a /2〈011〉 super partials bounding an anti phase boundary (APB). Dislocations dissociated into a /3〈112〉 super Shockley partials bounding a superlattice intrinsic stacking fault (SISF) are also common debris. The majority of the SISFs are truncated loops, i.e. the partials bounding the SISF are of similar Burgers vector. These faulted loops are generated from APB coupled dislocations, according to a mechanism for formation of SISFs proposed by Suzuki et al , and recently modified by chiba et al . The APB energies for {111} and {010} slip planes are measured to be 144±20 mJ/m 2 and 102±11 mJ/m 2 respectively, and the SISF energy has been estimated to be 12 mJ/m 2 in this alloy. It is concluded that the dislocation structure in Ni 74.5 Pd 2Al 23.5 alloy deformed at room temperature is similar to that in binary Ni 3Al, and the difference in fault energies between these two alloys is small. Thus, it seems unlikely that the enhancement of ductility of Ni 74.5 Pd 2Al 23.5 results from only such a small decrease of the ordering energy of the alloy. SISF bounding dislocations also have no apparent influence on the ductilization of Ni 74.5 Pd 2Al 23.5 alloy.

High-density tiling arrays provide closer view of transcription than regular microarrays and can also be used for annotating functional elements in genomes. The identified transcripts usually have a complex overlapping architecture when compared to the existing genome annotation. Therefore, there is a need for customized tiling array data analysis tools. Since most of the initial tiling arrays were conducted in eukaryotes, data analysis methods are well suited for eukaryofic genomes. For using whole-genome tiling arrays to identify previously unknown transcriptional elements like small RNA and antisense RNA in prokaryotes, existing data analysis tools need to be tailored for prokaryotic genome architecture. Furthermore, automation of such custom data analysis workflow is necessary for biologists to apply this powerful platform for knowledge discovery. Here we describe TAAPP, a web-based package that consists of two modules for prokaryotic tiling array data analysis. The transcript generation module works on normalized data to generate transcriptionally active regions （TARs）. The feature extraction and annotation module then maps TARs to existing genome annotation. This module further categorizes the transcription profile into potential novel non-coding RNA, antisense RNA, gene expression and operon structures. The implemented workflow is microarray platform independent and is presented as a web-based service. The web interface is freely available for acedemic use at http：//***/TAAPP-HTML/.
