45 female patients with polycystic ovary syndrome took thioctic acid (Thioctacid-HR), 600 mg (n = 25) or high protein diet (n = 20). Fast insulin and glucose stimulus insulin were investigated before and after 3 months taken treatment. The use of thioctic acid, 600 mg is a new effective pathogenetics therapy of polycystic ovary syndrome on influence of hyperinsulinemia, HOMA-IR index and ovary volume in female patients with polycystic ovary syndrome.

建立了SO(8)同位旋标量、同位旋矢量及总的配对基与微观壳模型坐标空间部分的Elliott SU(3)基之间的对应关系。从该代数间的互补关系导出了在壳模型的粒子数守恒代数U(4?)中所包含的具有同位旋T及自旋S的Wigner超多重态(不可约)表示。其重要性在于,该结果能用于研究对相互作用和四极-四极相互作用在核谱中的竞争效应并揭示其配对基中的SU(3)组份。虽然仅展示了该理论对ds壳的计算,其方法也适用于研究多壳的情形。

The strengths and weaknesses of different online technologies and learning methods have been examined by combining the blended learning program with practical work on institutional e-learning projects. There are differences between the traditional e-learning system and the new E-Learning 2.0 training. At present time, the new technologies provided by Web 2.0 better correspond to the needs of both students and teaching staff. The new Web 2.0 allows the ＂promoting of individual creativity＂, together with the ＂use of collective intelligence＂. A comparison of the two development stages of the e-learning tools has been completed and the advantages of E-Learning 2.0 are shown. The main components of Web 2.0 are provided and the use ofwiki as an up-to-date collaboration tool for on-line teamwork is shown.

Open Journal of Applied Biosensor 2013年第1期2卷 12-19页

Urea Amperometric biosensor was obtained on the base of nanostructured polypyrrole (PPy) and poly ortho- phenylenediamine (POPDA). The optimal conditions for monomer electropolymerization were determined. The effect of supporting electrolyte and number of deposition cycles on the OPDA and Py electropolymerization were studied. It was proved that POPDA and PPy were affected by pH changes and responded to the ammonium, product of urease catalyzed reaction. SEM images of the modified Pt/PPy electrode were presented. The cycle voltammograms and chrono amperometric curves of Pt/POPDA/urease and Pt/PPy/urease electrodes were studied. A good linear relationship was observed for Pt/POPDA/urease electrode in a concentration range from 6.7 to 54 mMurea. For Pt/PPy/urease electrode the linear relation in the range from 0.02 to0.16 mMurea was determined. The entrapped carbon nanotubes (CNT) in PPy film and the bipolymer layers were prepared for construction of Pt/PPy/CNT/urease, Pt/POPDA/PPy/urease and Pt/PPy/POPDA/urease biosensors. Obviously, the addition of POPDA to the composition of the two biosensors (Pt/PPy/POPDA/urease and Pt/POPDA/PPy/urease) reduced their sensitivity to urea. Pt/РPy/CNT/urease and Pt/РPy/ urease biosensors were 173 and 138 times more sensitive to urea than biosensor without PPy (Pt/POPDA/urease biosensor). It was found, that the performance of Pt/PPy/CNT/urease electrode was the best from the five obtained biosensors: linear range of urea concentrations—from 0.02 to0.16 mM;sensitivity—15.22 μA/mM and detection limit— 0.005 mM urea.

Using the ray method, an investigation has been carried out on the structure of caustics in the wa- veguide assuming the canonical distribution of the sound velocity with depth. Monochromatic point source of sound was on the axis of the waveguide. There is considered water rays only. It is shown that the spatial part of the phase of a running sound wave does not contain the wave propagation direction and is always a positive quantity. When the trajectories are calculated, it is assumed that inversion of rays occurs at an angle of total internal reflection where the reflection coefficient is equal to unity. This eliminates the horizontal part of the trajectories. At other points, the reflection coefficient is assumed to be zero, and the passing coefficient is equal to unity. With this change in the calculation of ray’s trajectories, the basic structure of the caustics remained the same. It is shown that the boundary line of the caustic is a number of foci in which rays intersect with similar angles out of the source and have neighbour times of propagation. Structure of the sound field along the boundary line of the caustic is periodic. Its period coincides with the wavelength of the field radiated by the source.

第二语言学习动机研究始于20世纪下半叶,很快便成为教育研究界的热议话题。然而,长期以来关于第二语言学习动机的研究大多集中在英语学习动机的研究上。近十年来,该领域的学者开始强调研究英语以外语言学习动机的重要性。同时,当今学者们面临的一大新问题是社会、政治、经济等因素如何影响学生学习外语的动机。基于这两大趋势,本文将针对俄罗斯大学生在新冠疫情背景下学习汉语的动机展开深入研究。首先,文献综述追溯了第二语言学习动机研究的历史,并围绕汉语学习动机研究和俄罗斯学习者汉语学习动机研究进行了述评。然后,为了探究俄罗斯大学生在新冠疫情下的汉语学习动机,笔者收集了100份俄罗斯大学生的调查问卷,根据学生的性别和年龄对数据进行了分析,并借助与新冠疫情相关的一些假设阐释了新冠疫情对俄罗斯大学生学习汉语的动机可能产生的影响。根据调查结果得出了以下结论:1)在新冠疫情下俄罗斯大学生学习汉语的动机很强。数据分析显示,目前俄罗斯大学生的融入型动机比工具型动机更为强烈;2)不同性别人群总动机之间不存在显著差异性;3)不同年龄段的俄罗斯大学生学习汉语的动机存在明显差异,即学习外语的动机随着年龄的增长而下降;4)新冠疫情对俄罗斯大学生学习汉语的兴趣和动机的影响非常明显,这种影响具有个体化表征。最后,根据得出的结论,从学生层面、教师层面和学校管理层面出发,提出相应的激发和维持俄罗斯大学生学习汉语动机的对策。希望本研究的结果不仅能够引起学者对俄罗斯学生汉语学习动机现状的关注,同时为未来研究社会、政治、经济和语言现象等因素对第二语言学习动机影响提供参考。

A series of block copolymers consisting of an isotropic (polystyrene) block and a side-chain liquid crystallineblock (LC) have been studied using small-angle X-ray scattering and dielectric spectroscopy. The triblock copolymer (PS-LC-PS) displays an order-to-order transition (OOT) together with the isotropic/nematic transition of the LC phase. The seriesof diblock copolymers show no clear OOT but the phase diagram differs from that of non-LC block copolymers. Thesegmental dynamics as measured with dielectric spectroscopy is dominated by the α and δ relaxation of the LC block. Bothdisplay a WLF like temperature dependence. The relaxation times are influenced by the constraints of the nanoscale *** are decreased for the LC confined in the domain as compared to the LC in the continuous matrix.

在全球化的世界中,外交的目的是建立两国之间持久的双向关系和理解。这是直接通过人与人交流,与官方的政府接触不同。人与人之间的联系,作为公共外交的工具,需要定性和定量的评估。人文交流的主要特征是以国际教育、文化交流和科技协作为基础的。人文交流中的国际教育合作是促进国家交往优先事项和利益的主要工具之一,是国家软实力的体现。基于中国与乌克兰友好合作关系,为国际教育合作提供了良好的基础,合作渠道包括中小学、孔子学院、乌克兰语和文化中心、大学。为了实现公共外交的全部利益,国际教育合作必须包括出入境学生双向流动、跨国教育合作、援助和发展能力建设等。通过国际教育项目的实现、研究合作、技能开发和整体的人文交流之间的联系。中国国际教育合作是一种有效的、持久的公共外交模式,非常适合当今全球化趋势和高度联系的世界。本文的主要内容分为三个章节。第一章主要讲述了文化与教育领域的国际合作及人文交流。公共外交的途径以及与教育的不可分割性、同时讲述了教育的重要性等重要的理论信息。本文第2章和第3章主要论述中国与乌克兰文化、教育和科技领域之间合作的情况、问题及建议。本文的创新之处在于,由于地域原因,乌克兰和中国在文化和高等教育领域的合作处于发展阶段,在这种情况下,我们应该做更多的工作和研究。特别是在“一带一路”倡议的背景下,为了加深两国的合作交流,乌克兰应积极参与丝绸之路经济带的项目,通过互访、合作网络、研讨会等形式来定期交流合作需求和方法,以加深对乌克兰和中国之间的了解并建立持久、深入的信任关系。同时中国政府也应将通过更多的人文交流计划来巩固已有的合作成果。
