控制实验表明,不同物种对每个环境因子变化变量产生的响应也存在着差异。植物往往对营养元素的变化反应最为强烈,尤其是氮素的增加。夏季增温实验表明,木本植物对温度的升高表现出了积极的响应,而地衣、苔藓类植物的丰富度却因增温而降低。物种对增温的响应主要受水分有效性和雪覆盖程度控制。在气候保持湿润的情况下,伴随着夏季温度的升高,许多无脊椎动物种群的数量都有所增加。实验表明,CO_2浓度和紫外线B(Uv-B)辐射的增加对植物和动物影响较小,但是,一些微生物和真菌却对紫外线B辐射的增加非常敏感,甚至可能会因此产生一些诱导突变而引起流行传染病的爆发。苔原土壤的加温、CO_2浓度的升高以及矿物质营养的改善一般都会增加微生物的活动。在温带气候中,藻类往往比蓝藻细菌更占优势。冬季结冰-解冻过程的增加会导致冻壳的形成,从而会大大降低许多陆生动物的冬季存活率,改变这些动物群体的动态过程。厚的积雪会使驯鹿等植食性动物很难采食到雪下的草类植物,同时也不利于其逃避食肉动物的追捕。而无雪期的提前到来则可能会加速植物的生长。物种对气候变化的响应最初可能出现在亚种这一水平上:一个具有很高遗传/群系多样性的北极植物或动物物种,演化历史已经使其具有一种适应不同环境条件的能力,这将使它们能够很快适应未来的环境变化。本土知识(IK)、航空照片和卫星图像表明一些物种的分布已经发生了变化:北极植被更加趋向灌木化,而且生长也更加旺盛;北极驯鹿的分布范围最近也发生了变化一些原来在树线以南区域活动的害虫和鸟类也在北极被发现。与此相对应,大多数在北极地区进行繁殖鸟类的数量却都在下降。根据一些模型的预测,随着气候的变暖,苔原带鸟类的数量将会大幅度地下降。据物种-气候响应模型预测,由于受到气候变暖的影响,北极地区现有物种在未来的潜在分布范围都将大大缩小和向北退缩,而一些无脊椎动物和微生物则很可能会迅速向北扩展到北极地区。

Effects of two doses of the anti-diabetic drug, metformin （MF）, on hormonal and metabolic levels of serum of non-diabetic male Wistar rats with 1,2-dimethylhydrazine （DMH）-induced colon tumor adenocarcinomas were studied. Carcinogenesis in the animals was also observed. Rats with DMH-induced colon adenocarcinomas had elevated levels of serum glucose, insulin, insulin- like growth factor-l, total cholesterol, triglycerides, catalase, malonic dialdehyde, glycated hemoglobin, aspartate aminotransferase, and alanine aminotransferase and decreased hemoglobin. Treatment with two doses of MF normalized maiority of these changes in DMH-treated rats, whereas the drug was ineffective in rats without DMH treatment. The only exception was the decreased triglyceride levels in MF-treated rats. A 100 mg/kg dose of MF increased DMH-induced exophytic colon carcinomas and decreased endophytic tumors compared with untreated rats. Moreover, both MF doses increased DMH-induced and highly differentiated tumors and decreased the invasiveness of colon carcinomas compared with rats provided with DMH and water. Therefore, effects of MF on metabolic homeostasis are critical for preventing colon cancer.

The brain is a unique organization in nature, possessing the ability for psychic activity, which manifests itself in thoughts, feelings and emotions. In present days, numbers of mathematical methods for analysis of electroencephalogram (EEG) were developed with continuous wavelet transform being one of the most successive approaches for studying of brain activity. This paper is aimed to develop methods for investigation of psychic brain activity with help of continuous wavelet analysis of EEG. Ability of human to realize semantic content of the image presented on the screen was tested. Experiment was accompanied with simultaneous EEG recording, which was held with developed software and PC-based experimental setup. The information capabilities of continuous wavelet transform-based method for EEG analysis were improved for the recognition of specific patterns in human brain activity. Comparative wavelet analysis was carried out for EEG recordings at the moment of awareness of the semantic content of the image and for EEG recordings in the absence of conscious (subjective) perception of the semantic content of the image. Significant differences were shown in the alpha rhythm of EEG for the moments of awareness of the semantic content of the image and for the moments of absence of conscious perception. Continuous wavelet analysis of EEG showed that the alpha rhythm is the main EEG rhythm, which can be used to estimate the presence of subjective perception of the visual image. Significant differences were shown in the alpha rhythm of EEG for the moments of awareness of the semantic content of the image and for the moments of absence of conscious perception. Conducted studies allow to conclude that revealing of brain activity related to visual image awareness is possible through analysis of EEG.

本文致力于现代文明间的对话。19世纪,欧洲社会科学家对其他文化产生了积极的兴趣,对文明的研究研究兴趣由此开始。欧洲人面临着不同的哲学,美学,物质文化和非西方社会的生活方式。于是出现了文明理论和文明研究。这一概念侧重于社会和文化发展的多线性,对社会和文化系统的特定类型进行识别,并强调其独特性。新文明理论的形成与欧洲中心社会发展理论的形成对立。早在20世纪末—21世纪初,唯物主义历史社会学就已成为研究各种文化,社会和文明的理论及方法论基础。唯物主义历史社会学旨在研究全球普遍化过程的辩证矛盾以及不同社会和文明对这些过程的局部反应。历史唯物主义,特别是在全球社会历史变化与文明物质基础变化的相互影响研究中,在很大程度上是现代历史社会学的理论和方法论基础。

A first search for the Ξ_(bc)^(+)J/ψΞ_(c)^(+) decay is performed by the LHCb experiment with a data sample of proton-proton collisions, corresponding to an integrated luminosity of 9 fb−1 recorded at centre-of-mass energies of 7, 8, and 13 Tev. Two peaking structures are seen with a local (global) significance of 4.3(2.8) and 4.1(2.4) standard deviations at masses of 6571 and 6694 Mev/c2, respectively. Upper limits are set on the Ξ+bc baryon production cross-section times the branching fraction relative to that of the B+c→J/ψD+s decay at centre-of-mass energies of 8 and 13 Tev, in the Ξ+bc and in the B+c rapidity and transverse-momentum ranges from 2.0 to 4.5 and 0 to 20Gev/c, respectively. Upper limits are presented as a function of the Ξ+bc mass and lifetime.

The Review summarizes much of particle physics and *** data from previous editions,plus 3,062 new measurements from 721 papers,we list,evaluate,and average measured properties of gauge bosons and the recently discovered Higgs boson,leptons,quarks,mesons,and *** summarize searches for hypothetical particles such as supersymmetric particles,heavy bosons,axions,dark photons,*** the particle properties and search limits are listed in Summary *** also give numerous tables,figures,formulae,and reviews of topics such as Higgs Boson Physics,Supersymmetry,Grand Unified Theories,Neutrino Mixing,Dark Energy,Dark Matter,Cosmology,Particle Detectors,Colliders,Probability and *** the 117 reviews are many that are new or heavily revised,including new reviews on Pentaquarks and Inflation.
