中国典型砖形黑茶非挥发物的代谢组学分析

为探究我国典型砖形黑茶代谢物轮廓的规律,以及砖形黑茶与黑茶真菌在代谢物种类方面的关系,本研究利用基于液相色谱-质谱联用的非靶向代谢组学和基于特征物信息的质谱分子网络技术,对我国典型的砖形黑茶(湖北青砖茶、四川康砖茶、湖南的黑砖茶、花砖茶和茯砖茶、陕西的茯砖茶)以及茶鲜叶和分离自黑茶的多种真菌进行代谢组学分析。结果表明,砖形黑茶的非挥发性代谢物轮廓更倾向于按照生产地区进行分类,一组是来自湖南和陕西的砖形黑茶,而另一组是来自四川和湖北的砖形黑茶;决定其代谢物轮廓分组的最主要因素是砖茶含梗率,来自四川和湖北的砖形黑茶含梗率明显高于另一组;造成两组砖形黑茶轮廓差异的主要原因是湖南和陕西的砖形黑茶中有更高含量的黄烷-3-醇类和大部分氨基酸及其衍生物等代谢物;针对砖形黑茶和真菌代谢物的分子网络分析发现,在砖形黑茶中,尤其是在康砖茶中广泛分布着源自真菌的线性和环状二肽;在茯砖茶中有着结构种类丰富的异戊烯基二酮哌嗪类化合物,这类化合物来自于冠突散囊菌,因此,真菌为砖形黑茶贡献了种类丰富的代谢物。本实验结果可为全面了解和认识我国典型砖形黑茶的化学物质基础提供理论参考。

Comparison of Morphological Microstructure of Vitrified and Normal Shoots of Aronia melanocarpa Elloit

The Aronia melanocarpa El oit was used as test material. The microstruc-ture of normal and vitrified shoots and the characteristics of their stomas on leaf surface were compared by paraffin section and leaf epidermis-tearing method. The results showed the palisade tissue of Aronia melanocarpa El oit consists of 2-3 lay-ers of cells. The stomas on lower epidermis cave in, and are smal and dense. There are abundant vessels and sieve tubes in stems. ln contrast, the main veins of vitrified shoots are unobvious, messy and irregular. The boundary between pal-isade tissue and spongy tissue is not obvious. The stomas open circularly and bigly. The stems are swel ing and thick, but the pith parenchyma cells are broken.

Infection of the Anther-smut Microbotryum violaceum in Populations of Silene dioica: Variation in Floral Morphology, Patterns of Spore Deposition and Pathogen-Pollinator Mediated Selection

The anther-smut Microbotryum violaceum ( Brandenburger and Schvinn) G. Deml. and Oberw.) causes a systematic infection of its host Silene dioica ( L.) Clairv., resulting in sterility and production of teliospores (dispersal propagules) in flowers. These spores are transmitted to healthy plants mainly by flower visitors. The behavioral responses of flower visitors to a variation in floral characters are not only likely to affect rates of pollen export/import, but also the rate of spore deposition and probability of disease. In a transplantation experiment, using plants from four different populations, we tested for correlation between variation in female floral morphology and patterns of spore and pollen deposition, and a resulting risk of disease. The source populations in this experiment were located on four islands in Skeppsvik archipelago in northern Sweden, and represented a gradient of disease incidence from completely healthy ( Island 1), low incidence ( Island 2) to high incidences ( Islands 3 and 4) of disease. Fifty plants from each population were transplanted to the center, of the population on Island 4. There were significant differences among the transplants in floral characters, i.e. corolla size, style length and ovule number. Plants from the non-diseased population had larger flowers and longer styles than plants from the highly diseased populations. Numbers of pollen grains and spores deposited on flowers were strongly and positively correlated. We found that plants originating from the non-diseased population captured approximately 4 times more pollen and 9 times more spores, per flower than die individuals from the resident population (Island 4, population 4). The incidences of disease among plants, from the four populations differed significantly, and was 37%, 20%, 18% and 0 for populations 1, 2, 3 and 4 respectively. In a survey of ten populations we found a significant negative correlation between the mean style length ( positively correlated with corolla size and ovule number) among healthy plants and incidence of disease in these populations. The potentiality for pathogen-pollinator mediated selection oil floral characters; and consequences for gone flow between populations of Silene dioica are discussed.

Quantum Tunneling Radiation of Reissner-Nordstrom de Sitter Black Hole with a Global Monopole

Applying Parikh＇s quantum tunneling model, we study the quantum tunneling radiation of Reissne- Nordstrom de Sitter black hole with a global monopole. The result shows that the tunneling rates at the event horizon and the cosmic horizon are related to Bekenstein-Hawking entropy if we take the energy conservation into consideration, and the true radiate spectrum is not precisely thermal.

Gravitational Radiation of Binaries Coalescence into Intermediate Mass Black Holes

This paper discusses the gravitation waveforms of binaries coalescence into intermediate mass black holes(about 30 times of the solar mass).We focus on the non-spinning intermediate mass black hole located less than 100 Mpc from earth.By comparing two simulation waveforms(effective one body numerical relativity waveform(EOBNR),phenomenological waveform),we discuss the relationship between the effective distance and frequency;and through analyzing large amounts of data in event,we find that the phenomenological waveform is much smoother than EOBNR waveform,and has higher accuracy at the same effective distance.

The Logic of Incarnation： Hegel＇s Use of Plato＇s Philebus in the Shorter Logic and in the Lectures on the Philosophy of Religion

Hegel uses Plato＇s classical text, Philebus, in two of his most important texts, the so called Shorter Logics, the first part of the famous Encyclopedia of Philosophical Sciences and in The Lectures on the Philosophy of Religion. The aim of this article is to analyze how can this two references be read together as to form a relationship between logic and religion in the very heart of Hegelian philosophy. In the first case, Hegel analyzes Plato＇s text within the context of his Doctrine of Being, specially from §§ 89 to 95, which deal with the question of determinate being. In The Lectures on the Philosophy of Religion, on the other hand, the reference appears in the 1824 Lectures in a particularly complex chapter called ＂The Transition to the Speculative Standpoint of Religion,＂ in which Hegel affirms not only that such a speculative standpoint is the only one in which religion can be truly grasped, but also that the Christian concept of ＂incarnation of God＂ is the ＂speculative midpoint＂ of religion. It will be argued, therefore, that the ontological question of determination and actuality, as exposed in the Shorter Logics, is fundamental to the metaphysics of Christian Religion as Hegel understands it not only in his Philosophy of Religion, but arguably in his whole philosophy.

Exploring Image Culture Through Narrative： A Study on Jennifer Egan＇s Twitter Fiction Black Box

Notable for the completeness with which it surrenders formally and artistically to the textual dictates of Twitter, Jennifer Egan＇s 2012 short science fiction Black Box is one of the most triumphant and fully-fledged fictions written in the form of new media. This paper explores the Twitter narrative employed in Black Box, pointing out that the serialized tweeting format of the story released via computer, mobile phone, or other electronic equipments brings readers immediate reading experience, allowing readers to sense the same feelings as the protagonist does. Through the experimental serialization of＂Twitter＂ narrative, Egan expresses her concerns and worries about the security of the American security as well as the whole world in the post-＂9.11＂ period and at the same time she embraces the virtues and pleasures of traditional storytelling delivered through a wholly new digital format. This paper concludes that Black Box is perhaps one of the boldest experiments of narrative form and is direct exploration into the contemporary image culture.

Heavy Metals in Water and Bottom Sediments of Odessa Region of the Black Sea

The paper presents the results of a comprehensive monitoring of the polygon： ＂Odessa Region, north-western part of the Black Sea＂ for the period 2009-2011. It is shown that most of the copper and nickel is brought into the sea from the catchment area, and zinc and cadmium are mainly of the autochthonous origin. It is found that in 2010, after heavy rains, the area of bottom sediments contaminated by copper and nickel was increased. The main source of copper in the sea is vast vineyards.

Hawking Tunneling Radiation of Black Holes in Deformed Horava-Lifshitz Gravity

Tunneling of scalar particles and Dirac particles from a black hole in the deformed Horava-Lifshitz gravity is discussed in this paper. We consider the case that the dynamical coupling constant λ= 1, when it reduces to Einstein＇s General Relativity at large scales and the black hole behaves like the Reissner-Nordstr6m black hole. The result shows that though the black hole entropy bears logarithmic correction, the tunneling probability is still related to its differences for the scalar particles and Dirac particles.

The only purple-flower species in Actaea L.is pollinated by a hornet

Examining the pollination biology of plant species is not only crucial for enhancing our understanding of their reproductive biology,but also essential for elucidating their adaptation and evolutionary history.Here,we investigated the breeding system and pollination biology of two closely related species in Actaea.The flower of A.purpurea is unique in the genus with purple and chartaceous(paper-like)sepals,fewer stamens with yellow anthers and purple filaments.Through three seasons of field observation and exclusion experiments,we determined that A.purpurea was primarily pollinated by a hornet species,Vespa bicolor,which also served as the most efficient pollinator.In contrast,A.japonica was primarily pollinated by large flies.Actaea purpurea exhibited a significantly higher cumulative nectar volume than A.japonica,which could be a crucial factor in attracting V.bicolor.A control experiment further demonstrated that removing the nectar leaf(petal)significantly decreased the visiting frequency of V.bicolor.Breeding system studies revealed that both species were self-compatible,yet they primarily underwent outcrossing in natural habitats.Our study presents a compelling case of possible pollinator shift in A.purpurea accompanied by morphological divergence.A more in-depth investigation of this system would offer crucial insights into the extent to which pollinators are involved in the plant speciation process and whether they contribute to reproductive isolation between closely related species.

On the Contemporary Construction of the Chinese System of Academic Discourse

As an important academic issue, the contemporary construction of the Chinese system of academic discourse has attracted increasing attention in recent years. Questions needing further reflection and exploration are： What does the genesis and expansion of this topic actually mean？ Within what horizon can we reveal its fundamental nature and draw further conclusions？ What intellectual task will be presented to us in the course of fixing its direction？ An in-depth probe into these questions, that is, the core issue in the contemporary construction of the Chinese system of academic discourse, is how contemporary academic discourse can enter deep into the specific content ushered in by our historical practice, so that this content can be truly grasped intellectually and studied academically.
