目的对海南省福寿螺进行分子鉴定,完成遗传多样性和亲缘关系研究,为识别和防控福寿螺的持续扩散提供依据。方法基于线粒体细胞色素c氧化酶I(COI)和16S核糖体脱氧核糖核酸(16S rDNA)基因,对海南省18个县市61个采样点采集的福寿螺样本,进行系统发育分析及种群遗传学研究。采集1050只福寿螺,随机对其中632只和577只进行COI和16S rDNA基因测序。从GenBank数据库下载序列构建数据库,COI和16S rDNA数据库分别有1465和641条序列。使用MEGA X和DnaSP软件进行系统发育和遗传多样性分析。结果小管福寿螺为海南省优势种(79.9%)。小管福寿螺和隐秘福寿螺在海南17个市县同时存在。基于COI基因,小管福寿螺分为A支(与来自日本和中国福寿螺亲缘关系密切)、B支(与来自日本、菲律宾、马来西亚和中国福寿螺亲缘关系接近)和C支(与来自马来西亚、日本、阿根廷、巴布亚新几内亚、缅甸、智利和中国福寿螺亲缘关系近)。基于16S rDNA基因,小管福寿螺分为A支和B支系(与来自马来西亚、阿根廷、菲律宾、美国和中国福寿螺亲缘关系较近)。单倍型网络分析表明,基于小管福寿螺的COI和16S rDNA基因,分别有4个和3个单倍型。隐秘福寿螺只表现出单一的COI单倍型。保亭黎族苗族自治县的福寿螺样本单倍型和核苷酸多样性最高(Hd=0.679,π=0.053),而琼海市和屯昌县之间的种群分化最大(F_(ST)=0.63)。小管福寿螺和隐秘福寿螺的遗传多样性较低。结论海南省小管福寿螺的COI和16S rDNA序列具有多态性。福寿螺可能被多次引入海南,其中隐秘福寿螺在海南省首次得到确认,尚未记录到斑点福寿螺的分布。海南省小管福寿螺和隐秘福寿螺的遗传多样性较低。

Experimental, clinical and epidemiologic studies have provided strong evidence that physical training has beneficial effects on cardiovascular health. Numerous investigations have demonstrated that exercise increases coronary blood flow and myocardial perfusion. Importantly, training also can stimulate angiogenesis and accelerate collateral vessel growth in animal models with coronary artery occlusion. Cardiac adaptation such as increased vascularity or capillary density has been evidenced after regular endurance exercises. More recently, several studies indicate that physical training induces high levels of myocardial heat shock protein and antioxidant protein expression, which may play an important role in myocardial protection against ischemia-reperfusion injury.

The Altyn Tagh fault zone (ATFZ) is one of the most striking features related to the India/Eurasia collision. Concurrent with the strike-slip movement， vertical uplift， and topographic building have formed a ～3 000–4 000 m height difference between the Tarim Basin (TB) and Tibetan Plateau. However， the spatial uplift characteristics and mechanism have not been well understood， particularly in the late Quaternary. This research presents a comprehensive geomorphic analysis to establish the late Quaternary tectonic uplift pattern for the entire ATFZ. We statistically excluded climatic and lithological factors that provided prominence for tectonism; combined with leveling data， river incision rate， and seismicity data， we reveal the along-strike and across-fault vertical deformation variations. The spatial distribution of the integrated geomorphic index (IGI) suggests significant differences between the two sides of the ATFZ. The IGI values decrease with slip rates in the northwestern side of the ATF， whereas wave-like in the southeastern side. The significant along-strike deformation difference between the two sides of the ATFZ may caused by differential rheology. These findings are crucial for assessing regional seismic hazards and providing new independent data to understand the late Quaternary deformation style of the northern boundary of the Tibetan Plateau.

Several examples that serve to validate the AHP/ANP with matrices hierarchies and networks are given in this paper. They are then followed by a discussion of the real numbers and how they are generated without the need for an absolute zero, and how they define an absolute scale of measurement that also does not need an absolute zero. In the AHP/ANP the measurement of an alternative depends on what other alternatives it is compared with. The result is that rank can change if alternatives are added or deleted, something that does not occur in one-at-a-time rating of the alternatives by comparing them with an ideal. An example is provided to show that this is natural and need not involve new criteria or change in judgments. A brief discussion of Utility Theory, the other multi-criteria theory, which uses interval scales to measure intangibles and some of its problems and paradoxes, is given. The references at the end include most of the papers that are adverse to the AHP with brief comments about several of them given in the paper.

Translocation of previously accumulated nitrogen and carbohydrates from vegetative tissue of the wheat plant is a major assimilate source for grain filling. This study was conducted to examine genotype differences in nitrogen and fructan translocation and their relationships to grain yield and protein content. Effects indicated that significant genotype differences existed for nitrogen accumulation at anthesis and fructan at milk stage and their translocation. Two high protein genotypes, Cunningham and PST90-19, accumulated more nitrogen before anthesis and had greater nitrogen translocation, but lower post-anthesis nitrogen uptake, than two low protein genotypes, SUN109A and TM56. Among plant parts, leaves were the major storage for tissue nitrogen and provided the overwhelming proportion of the total nitrogen translocation, whereas for fructan accumulation and translocation it was the stems. The two high protein genotypes had a higher percentage of their grain nitrogen derived from nitrogen translocation, while for the two low protein ones, it was from post-anthesis nitrogen uptake and assimilation. Increasing nitrogen application increased nitrogen accumulation and translocation, but decreased fructan accumulation and translocation. High grain protein content was associated with high nitrogen translocation from leaves, stems and the total plant, while high grain yield was related to high fructan translocation from stems and the total plant. Fructan translocation was negatively correlated to grain protein content. Nitrogen and fructan translocation were not correlated with each other.

The Analytic Network Process (ANP) is a multicriteria theory of measurement used to derive relative priority scales of absolute numbers from individual judgments (or from actual measurements normalized to a relative form) that also belong to a fundamental scale of absolute numbers. These judgments represent the relative influence, of one of two elements over the other in a pairwise comparison process on a third element in the system, with respect to an underlying control criterion. Through its supermatrix, whose entries are themselves matrices of column priorities, the ANP synthesizes the outcome of dependence and feedback within and between clusters of elements. The Analytic Hierarchy Process (AHP) with its independence assumptions on upper levels from lower levels and the independence of the elements in a level is a special case of the ANP. The ANP is an essential tool for articulating our understanding of a decision problem. One had to overcome the limitation of linear hierarchic structures and their mathematical consequences. This part on the ANP summarizes and illustrates the basic concepts of the ANP and shows how informed intuitive judgments can lead to real life answers that are matched by actual measurements in the real world (for example, relative dollar values) as illustrated in market share examples that rely on judgments and not on numerical data.

1 Results Palygorskite (PGS) is a chain-layer magnesium-aluminum silicate mineral. Because of its developed interior channels and large specific surface area, and thus considerable adsorption capacity, it has been studied for the application as one of environmental mineral adsorbents[1-3]. Cyclodextrins (CD) possess a hydrophilic exterior and a hydrophobic interior into which a variety of hydrophobic organic molecules maybe introduced. The CD molecule not only affects a hydrophilic cavity on the nanomet...
