  7. Regime Change and the Attempted Rehabilitation of Self: Ferenc Fodor and the Production of Communist Geography, 1948-1962

    Steven Jobbitt


    Full Text Available The communist takeover in Hungary after World War II presented obvious challenges, hardships, and even dangers for the conservative-nationalist scholars who were part of the intellectual elite of the interwar period. Marginalized within the new socio-political order that emerged after the communist consolidation of power in 1948-49, conservative-nationalist intellectuals who were not completely silenced by the communists either retreated from public life entirely, or else found themselves having to struggle to remain relevant within the state-socialist system then under construction. Though limited in what they could publish, and relegated to minor and often precarious positions within the scholarly community, former conservative-nationalist scholars were nevertheless granted limited spaces within which they could produce relevant and even important scholarship, and in so doing could also “reinvent” themselves—if in many cases only partially and perhaps opportunistically—as public intellectuals. Focusing on the life and work of Ferenc Fodor between 1948 and his death in 1962, this article explores the concrete ways that a once-prominent geographer of the interwar period continued to contribute to geographical knowledge production under communism, and how he used this scholarly work as leverage in his attempts to partially rehabilitate himself in the early communist period. Contributing to a growing body of critical work on Hungarian geography under communism (see articles by Márton Czirfusz and Róbert Győri in this issue, for example, this study helps to lay the groundwork for future research on the relationship between the politics of scholarly production and the spatial re-imagining of postwar Hungary.

  8. A Hungarian Writer’s Experience of the Mediterranean: On Ferenc Herczeg’s Szelek Szárnyán Travelogue/ Ship's Log

    Bence Erika


    Full Text Available One of the works of the much disputed and until recently often avoided oeuvre of Herczeg Ferenc is the attention-grabbing work entitled Szelek szárnyán [On the Wings of the Wind] (1905. a travelogue and a ship’s Jog. Its analysis casts another view on the life of this writer, bom in South Banat. who. at the beginning of the 20th century, sailed the Adriatic and the Mediterranean with his nephew in his sailing boat called Sirály (The Seagull - thus demonstrating and choosing a secessionist lifestyle, even abandoning Budapest -, and his inspiration by the sea reached a peak in this volume (Secessionist in every sense, advertising the beauties and values of the Adriatic. This prose work was created in the context of Rijeka, Zadar, Sibenik. Trogir, Split, Dubrovnik, and Boka Kotorska. which (apart from its Secessionist character, owing to its cross-artistic and multicultural features, blends various art forms and ways of expression. It gives a superb experience to the reader. The study interprets and analyses Ferenc Herczeg’s volume Szelek szárnyán as a complex genre created in a cross-artistic environment, with the objective to emphasize and present its special role and standing in Hungarian literature as well as in the field of fine and applied arts.

  11. Phase difference and inter ference between reflected cylindrical wave and head wave at a liquid/solid interface


    The reflected field of pulsed cylindrical waves from a liquid-solid interface is studied by the numerical method and the experimental method. The reflected field is calculated and shown in gray pictures. The calculated incident angles θn (n=1, 2, 3, ...) of a series of minimums (or nulls) on the reflected wavefront are presented. The measured angle of the minimum from Schlieren photograph is consistent with that by calculation. The appearance of minimums is explained by the interference between the refiected wave and the head wave, and by the radiated dissipation of the head wave. The leading phase angle of the head wave to the reflected wave is proved to be about 3π/4 by the numerical calculation.``

  13. Gene Silence ofPhytophthora infestans Induced by Plant-mediated RNA Inter-ference in Potato%植物介导的RNA干扰引起马铃薯晚疫病菌基因的沉默

    任琴; 王亚军; 郭志鸿; 李继平; 谢忠奎; 王若愚; 王立; 惠娜娜


    由致病疫霉(Phytophthora infestans)引起的晚疫病是最具毁灭性的马铃薯病害。为明确植物介导的RNAi沉默致病疫霉基因的有效性,本研究采用重叠延伸PCR技术克隆同时与晚疫病菌4个ces基因均同源的融合基因C1234,构建内含子连接的C1234反向重复序列植物表达载体,采用农杆菌介导法转化晚疫病易感马铃薯品种大西洋,经PCR和Southern杂交检测,获得129个转基因株系。离体叶片接种病原菌后,有97个转基因株系发病速度明显慢于野生型,接种6 d后病斑大小和霉层厚度均明显小于对照,并且叶片感病部位没有出现失绿斑,而野生型产生了明显的失绿斑。实时定量RT-PCR分析发现,发病延缓的叶片上致病疫霉4个纤维素合酶基因的表达水平明显低于野生型。本研究表明,转基因植株中产生的以晚疫病菌ces基因为靶标的dsRNA能够沉默致病疫霉相应基因表达,延缓发病进程。%Potato late blightcaused by Phytophthora infestans is the most devastating disease in potato. The objective of this study was to test the efficiency of plant-meidated RNAi in silencing genes in P. infestans and to find a new way to breed potato resistant to late blight. Over-lap PCR was employed to amplify a fused-geneC1234 simultaneously homologous to four cellulose synthase genes inP. infenstans. Then, a plant expression vector containing inverted repeat ofC1234was constructed and transferred to Atlantic, a potato variety severely susceptible to late blight by agrobacteria-mediated genetic transformation. A hundred and twenty nine regenerated lines were confirmed to be transgenic plants with PCR and Southern blot. When detached leaves were inoculated withP. infestans, 97 out of 129 transgenic lines delayed disease symptoms with smaller lesions and less hyphae com-pared to the wild type at six days after inoculation. Chlorotic spots did not appeared on leaves from transgenic lines while deve-loped severely on leaves from the wild type at the same day. mRNA accumulation of the four cellulose synthase genes fromP. infestanscolonized on leaves from transgenic plants with delayed symptoms was significantly lower compared to the wild type with Real-time RT-PCR.The results demonstrated that dsRNA ofC1234 generated in transgenic potato could induce homologous genes silence and delay the process of infection in intimately touchedP. infestans.

  14. Construction method for Bayesian network by fusing Experts’relative in-ferences%融合专家相对推断的贝叶斯网络构建方法

    杜元伟; 石方园; 杨娜


    为了解决依据专家知识推断贝叶斯网络中条件概率表时存在的个体推断信息缺乏有效性以及整体集成结果缺乏科学性的问题,提出了有利于实现判断对象更直观、判断方式更简便的推断信息约简机理,然后将层次分析法中两两比较与判断矩阵分别作为主观条件概率信息的提取手段与信息载体,构建了能够从宏微观推断信息中提取最优条件概率的专家相对推断方法,该方法一方面可以克服传统方法中因专家推断能力有限的现实约束而造成个体推断信息容易缺乏有效性的问题,另一方面也能够对专家个体推断信息进行有效综合集成、保证决策结果的科学性。在此基础上遵循由前至后的推断顺序提出了贝叶斯网络的构建过程,最后应用数值对比分析和案例模拟分析验证了提出方法的科学有效性和应用可行性。%In order to solve the problem of lacking effectiveness in the individuals inference and scientific in the overall integration results, which existed in the conditional probability tables in Bayesian network according to experts knowledge inference, the inferred information reduction mechanism is proposed to make judgment objects more intuitive and judgment modes more simple. Then the pair-wised judgment matrix in the Analytic Hierarchy Process(AHP)is used as an extraction means and information carriers of the subjective conditional probability. After that, the experts relative inference method for deriving optimal conditional probability from macro and micro information is constructed, the proposed method on one hand can overcome the problem of lacking effectiveness in individual inferred information caused by experts’limited concluding ability in the traditional method, on the other hand it is possible to make effective comprehensive integration of experts’inferred information to ensure scientific of the results. Then the construction process of Bayesian networks is proposed following an inference sequence of“anterior to later”. Finally a data comparison analysis and a case simulation analysis are employed to prove the present method to be scientific, applicable and feasible.

    A major limitation of exact inference algo- rithms for probabilistic graphical models is their extensive memory usage, which often puts real-world problems out of their reach. In this paper we show how we can extend in- ference algorithms, particularly Bucket Elim- ination, a special case of cluster (join) tree de- composition, to utilize disk memory. We pro- vide the underlying ideas and show promis- ing empirical results of exactly solving large problems not solvable before.

    Qin Yan; Zhen Han; Shi-wu Zhang; Jie Yang


    In this paper, a carangiform robotic fish with 4-DoF (degree of freedom) tail has been developed. The robotic fish has capability of swimming under two modes that are radio control and autonomous swimming. Experiments were conducted to investigate the influences of characteristic parameters including the frequency, the amplitude, the wave length, the phase dif- ference and the coefficient on forward velocity. The experimental results shown that the swimming performance of the robotic fish is affected mostly by the characteristic parameters observed.

  5. Sunflower cataract: do not forget Wilson's disease.

    Litwin, Tomasz; Langwińska-Wośko, Ewa; Dzieżyc, Karolina; Członkowska, Anna


    A 41-year-old man with liver cirrhosis of unknown aetiology for 6 years was admitted to our department to confirm the diagnosis of Wilson's disease. He consulted an ophthalmologist who suspected the presence of a sunflower cataract and Kayser-Fleischer ring. At admission, his liver function tests were modestly impaired (Child-Pugh C, 10 pts). Neurological examination was normal, but cognitive functions were mildly impaired. Based on the copper metabolism abnormalities and clinical manifestation, we diagnosed Wilson's disease (Ferenci score, 6 pts) and started treatment with d-penicillamine. Presenting the case we would like to emphasise the significance of the ophthalmological examination in Wilson's disease diagnosis.

  6. Control of two-photon quantum walk in a complex multimode system by wavefront shaping

    Defienne, Hugo; Walmsley, Ian A; Smith, Brian J; Gigan, Sylvain


    Multi-photon interferences in complex multimode structures - quantum walks - are of both funda- mental and technological interest. They rely on the ability to design the complex network where the walk occurs. Here, we demonstrate the control of quantum walks of two indistinguishable photons in a complex linear system - a highly multimode fiber - by means of wavefront shaping techniques. Using the measured transmission matrix of the fiber, we demonstrate the ability to address arbitrary output modes of the two-photon speckle pattern, and simultaneous control of the quantum inter- ferences. This work provides a reconfigurable platform for multi-photon, multimode interference experiments and a route to high-dimensional quantum systems.

  11. A Comparison between American and Chinese Classroom Management

    CHAI Xue-ting; FAN Xiao-bin


    The classroom is an episode of the school culture, a stage to show the idea of school, and a transmission position to spread national education philosophy. There are obvious differences in terms of American and Chinese classroom management in three aspects:the teaching objectives, the teaching environment, the solution of the classroom problem behavior, and these dif-ferences are caused by the distinction in values and culture. The comparison between American and Chinese classroom manage-ment is of great significance for learning from teaching experience of foreign countries and promoting students' comprehensive development.

    A robust interference canceller for Multi-Carrier Code Division Multiple Access(MC-CDMA) using Orthogonal Frequency Division Multiplexing (OFDM) in Rayleigh fading isproposed. This interference canceller is robust in the sense that it cancels Inter-Carriers Inter-ference (ICI) and is suitable for use in dispersive channels. To come up the effects of the signaldispersion, Doppler shifts and delay spreads on the performance of MC-CDMA systems over mo-bile fading channels, this interference canceller exploits the merit of the orthogonal signaling andpilot signals to evaluate the channel parameters. This interface canceller is well suited to work initerative turbo interference cancellation.

  1. On Wal-Mart’s Failure in China



    Wal-Mart, the world famous retailing giant, set its foot on the land of China 17 years ago. Now despite of its success elsewhere as well as its confidence and ambition to“conquer”the vast market China which shows great potential, Wal-Mart fails to reach its goal anyway. To be more exact, it is far from the goal. Considering its unexpected failure, this article mainly discusses why Wal-Mart has experienced such a hard time in China. The issue is analyzed from the following aspects, namely cultural dif-ference, distribution, management and public relationship.

Our aim was to clarify the mechanism of immune complex-mediated inflammation and modulation of the disease. CII pre-immunized DBA/1 mice were intravenously boosted with extravidin coupled biotinylated monomeric CII-peptide epitope (ARGLTGRPGDA and its complexes with biotinylated FcγRII/III specific single chain Fv (scFv fragment. Disease scores were monitored, antibody titers and cytokines were determined by ELISA, and binding of complexes was detected by flow cytometry and immune histochemistry. Cytokine and chemokine secretion was monitored by protein profiler microarray. When intravenously administered into collagen-primed DBA/1 mice, both CII-peptide and its complex with 2.4G2 scFv significantly accelerated CIA and increased the severity of the disease, whereas the monomeric peptide and monomeric 2.4G2 scFv had no effect. FcγRII/III targeted CII-peptide complexes bound to marginal zone macrophages and dendritic cells, and significantly elevated the synthesis of peptide-specific IgG2a. Furthermore, CII-peptide containing complexes augmented the in vivo secretion of cytokines, including IL-10, IL-12, IL-17, IL-23, and chemokines (CXCL13, MIP-1, MIP-2. These data indicate that complexes formed by the CII-peptide epitope aggravate CIA by inducing the secretion of chemokines and the IL-12/23 family of pro

  14. Playing with anthems: The formation of the cult of empress Elisabeth in Hungarian music

    Windhager Ákos


    Full Text Available In this paper I reveal how the cult of Empress Elisabeth affected the reception of three different volumes of Hungarian music. These three works are: Erzsébet-emlény (Elisabeth Memorial Album, 1854 edited by Kornél Ábrányi; Erzsébet (Elisabeth, 1854 opera by Károly Doppler, Ferenc Doppler and Ferenc Erkel; and Die Legende von der heiligen Elisabeth (The Legend of Saint Elisabeth, 1865 by Franz Liszt. In spite of their high artistic level, the first two works were banned by the cultural elite who interpreted them as Habsburgian political music after the downfall of the dual state. On the other hand, the intentionally apolitical oratorio by Franz Liszt was regarded by the same cultural elite as the highest standard of artistic representation of the Empress. As a consequence of parallel distribution of both imperially and nationally constructed memories, a strange diffusion appeared in the social sphere, especially in Hungarian cultural memory. Conflicting memories emerged due to the discrepancy between the original Hungarian political myth (Kossuth-myth and Empress Elisabeth’s cult. Using the terminology introduced by Claude Lévi-Strauss, I have labeled this situation as the clash of the cold and hot society in Hungary during the 19th century.

  16. 6th International Conference on General Inequalities


    The sixthInternational Conference on General Inequalities was held from Dec. 9 to Dec. 15, 1990, at the Mathematisches Forschungsinstitut Oberwolfach (Black Fa­ rest, Germany). The organizing committee was composed of W.N. Everitt (Birm­ ingham), L. Losonczi (Debrecen) and W. Walter (Karlsruhe). Dr. A. Kovacec ( Coimbra) served cheerfully and efficiently as secretary of the meeting. The con­ ference was attended by 44 participants from 20 countries. Yet again the importance of inequalities in both pure and applied mathematics was made evident from the wide range of interests of the individual participants, and from the wealth of new results announced. New inequalities were presented in the usual spread of the subject areas now expected for these meetings: Classical and functional analysis, existence and boundary value problems for both ordinary and partial differential equations, with special contributions to computer science, quantum holography and error analysis. More strongly than ever, the role played ...




    This paper is interested in a system of conservation laws with astiff relaxation term arised in viscoelasticity. The properties of a class of fully implicit finite dif ference methods approximating this system are analyzed, which include maximum principles, bounds on the total variation, L1-bounds, and L1-continuity estimates in term of some conserved physical quantity and the characteristic variables gener ated by difference schemes with proper initial data. These estimates are necessary for the existence of a bounded-total variation (BV) solution. Furthermore, we show that numerical entropy inequalities for some convex entropy pairs of the fully system hold.Keywords:Finite difference scheme, hyperbolic conservation laws,entropy inequality

  18. Periodic Relativity: Deflection of Light, Acceleration, Rotation Curves

    Zaveri V. H.


    Full Text Available Vectorial analysis relating to derivation of deflection of light is presented. Curvilinear acceleration is distinguished from the Newtonian polar conic acceleration. The dif- ference between the two is due to the curvature term. Lorentz invariant expression for acceleration is derived. A physical theory of rotation curves of galaxies based on second solution to Einstein’s field equation is presented. Theory is applied to Milky Way, M31, NGC3198 and Solar system. Modified Kepler’s third law yields correct orbital periods of stars in a galaxy. Deviation factor in the line element of t he theory happens to be the ratio of the Newtonian gravitational acceleration to th e measured acceleration of the star in the galaxy. Therefore this deviation factor can replace the MOND function.

  19. Orbit determination using incremental phase and TDOA of X-ray pulsar

    Rong JIAO; Lu-ping XU‡; Hua ZHANG; Cong LI


    X-ray pulsars offer stable, periodic X-ray pulse sequences that can be used in spacecraft positioning systems. A method using X-ray pulsars to determine the initial orbit of a satellite is presented in this paper. This method suggests only one detector to be equipped on the satellite and assumes that the detector observes three pulsars in turn. To improve the performance, the use of incremental phase in one observation duration is proposed, and the incremental phase is combined with the time dif-ference of arrival (TDOA). Then, a weighted least squares (WLS) algorithm is formulated to calculate the initial orbit. Numerical simulations are performed to assess the proposed orbit determination method.

  1. Optical Fiber Bragg Grating Michelson Interferometer

    JIANG Yi; JIANG Tian-fu; LIU Li


    A new Michelson interferometer based on fiber Bragg grating(FBG) is demonstrated. FBGs are used as reflectors, and the laser is replaced by a broadband source as input light in this interferometer. To demodulate the signals, a 3×3 coupler is used as a splitter. By combining with software demodulation, the outer inter ference can be obtained from the outputs of the interferometer. This kind of in terferometer can also be wavelength-multiplexed easily by composing a series Michelson interferometer. The experiment results show that the clear interference fringe can be obtained by adjusting the path difference to make it less than interference length of FBG. The signals are also demodulated.

  2. Adolescents and Young Adults Mates Selection

    María Martina Casullo


    Full Text Available The study sought to identify the relation between gender and age on mate pre- ferences using an intentional sample drawn in Buenos Aires city and its suburban area. A questionnaire adapted from a previous study developed by D.Buss (1990 requested subjects to rank each of 19 characteristics on its desirability in a mate. Subjects for this study were 900 adolescents and young adults aging 13 to 30 years old. Means and standard deviations were calculated as well as Spearman ́s Rho coefficients. High correlations between gender, age, and ordering were found. Mutual attraction and love, kindness and understanding and trust are cho- sen as the most important criteria. Phisically attractive is important for younger males. Similar political and religious background as well as chastity are conside- red among the less important criteria. 

  3. Switching variability index based multiple strategy CFAR detector

    Yang Li; Zhenyuan Ji; Bingfei Li; Gil Alterovitz


    A switching variability index (SVI) constant false alarm rate (CFAR) detector is proposed for improving the detection performance of VI-CFAR detectors in multiple targets back-grounds. When the presence of non-homogeneity in CFAR re-ference windows is indicated by a VI-CFAR detector, a switching-CFAR detector is introduced to optimize the performance of the VI-CFAR detector in homogeneous, multiple targets and clut-ter edge backgrounds. The structure and parameters selection method of the SVI-CFAR detector is presented. Comparisons with classic CFAR detectors and recently proposed detectors are also given. Theoretical analysis and simulation results show that SVI-CFAR detector maintains the good performance of the VI-CFAR detector in homogeneous and clutter edge backgrounds, while greatly improving the capacity of anti-multi targets.

  4. Passive ranging based on acoustic field interference structure using double arrays (elements)

    YU Yun; HUI Junying


    Two kinds of passive ranging algorithms are proposed combined with waveguide invariant theory based on the important characteristic of the ocean waveguide that the inter- ference structure is stable and can be observed in the low-frequency acoustic field, in order to explore the passive ranging method suitable for the towed line array sonar. The double arrays (elements) model is adopted, so the LOFARgram and bearing-time records of the each array (element) can be obtained. Then the frequency-time records can be extracted by processing the LOFARgram via Radon transform, so the passive ranging can be achieved combined the corresponding ranging algorithms. And the feasibility of the algorithms has been verified by simulation researches and positioning accuracy analysis.

  5. Phenomenographic Research Method

    Erdem ÇEKMEZ


    Full Text Available Phenomenography, an approach to educational research, emerged from the studies carried out by Ference Marton and his colleagues at the University of Göteborg, Sweden, in the early 1970s. Phenomenography is the empirical study of the different ways in which people experience, perceive, apprehend, understand, conceptualize various phenomena in the world around them. Not only this method has been used much in educational researches in Turkey, but also the books about research methods do not provide detailed information about this method in details. This study explains the aim, characteristics, historical background and how to ensure the generalization, validity and reliability of phenomenographic research outcomes, besides mentions to the studies in which phenomenographic research method was used. In addition, the differences and similarities between this method and methods similar to phenomenology are explained.

  8. Rapid Estimation of Enantioselectivity in Lipase-catalyzed Resolution of Glycidyl Butyrate Using pH Indicator

    WANG Ping; WANG Lei; WANG Li-cheng; LI Chun-yuan; WANG Ren; MIAO Qing-hua; YANG Ming; WANG Zhi


    A simple method for rapid estimation of the enantioselectivity of lipase in resolution of chiral esters is described. The enantioselectivity of lipase can be estimated rapidly through comparing the dif-ference of hydrolysis rates for the racemic ester and its slow reacting enantiomer under the same condition because the difference mainly depends on the enantioselective ratio(E values). The higher the enantiose-lectivity of enzyme, the larger the difference of hydrolysis rate. The bromothymol blue(BTB) can be used as pH indicator for microplate reader to monitor the formation of acid in lipase-catalyzed hydrolysis ofesters. This method has been successfully used to rapidly estimate the enantioselectivity of several lipases in the resolution of glycidyl butyrate.

  9. DANIO-CODE: Toward an Encyclopedia of DNA Elements in Zebrafish.

    Tan, Haihan; Onichtchouk, Daria; Winata, Cecilia


    The zebrafish has emerged as a model organism for genomics studies. The symposium "Toward an encyclopedia of DNA elements in zebrafish" held in London in December 2014, was coorganized by Ferenc Müller and Fiona Wardle. This meeting is a follow-up of a similar previous workshop held 2 years earlier and represents a push toward the formalization of a community effort to annotate functional elements in the zebrafish genome.

    CUI Ziguan; GAN Zongliang; TANG Guijin; LIU Feng; ZHU Xiuchang


    Motivated by the importance of Human visual system (HVS) in image processing, we propose a novel Image signature based mean square error (ISMSE) metric for full reference Image quality assessment (IQA). Efficient image signature based describer is used to predict visual saliency map of the reference image. The saliency map is incorporated into luminance diff erence between the reference and distorted images to obtain image quality score. The eff ect of luminance diff erence on visual quality with larger saliency value which is usually corresponding to foreground objects is highlighted. Experimental results on LIVE database release 2 show that by integrating the eff ects of image signature based saliency on luminance dif-ference, the proposed ISMSE metric outperforms several state-of-the-art HVS-based IQA metrics but with lower complexity.

  14. Analysis of interlaminar stress and nonlinear dynamic response for composite laminated plates with interfacial damage

    F. H. Zhu; Y. M. Fu


    By considering the effect of interfacial damage and using the variation principle, three-dimensional nonli-near dynamic governing equations of the laminated plates with interfacial damage are derived based on the general six-degrees-of-freedom plate theory towards the accurate stress analysis. The solutions of interlaminar stress and nonlinear dynamic response for a simply supported laminated plate with interfacial damage are obtained by using the finite dif-ference method, and the results are validated by compari-son with the solution of nonlinear finite element method. In numerical calculations, the effects of interfacial damage on the stress in the interface and the nonlinear dynamic response of laminated plates are discussed.

  15. Sexually Transmitted Diseases on Bipartite Graph

    WEN Luo-Sheng; ZHONG Jiang; YANG Xiao-Fan


    We study the susceptible-infected-susceptible (SIS) epidemic model on bipartite graph. According to the dif-ference of sex conception in western and oriental nations, we construct the Barabasi Albert-Barabasi Albert (BA-BA) model and Barabasi-Albert Homogeneity (BA-HO) model for sexually transmitted diseases (STDs). Applying the rate equation approach, the positive equilibria of both models are given analytically. We lind that the ratio between infected females and infected males is distinctly different in both models and the infected den-sity in the BA-HO model is much less than that in the BA-BA model. These results explain that the countries with small ratio have less infected density than those with large ratio. Our numerical simulations verify these theoretical results.

  16. Ceramic Carbon/Polypyrrole Materials for the Construction of Bienzymatic Amperometric Biosensor for Glucose


    A novel amperometric glucose biosensor was constructed by electrochemical formation of a polypyrrole (PPy) membrane in the presence of glucose oxidase (GOD) on the surface of a horseradish peroxidase (HRP) modified ferrocenecarboxylic acid (FCA) mediated sol-gel derived ceramic carbon electrode. The amperometric detection of glucose was carried out at +0.16 V (vs. SCE) in 0.1 mol/L phosphate buffer solution (pH 6.9) with a linear response range between 8.0×10-5 and 1.3×10-3 mol/L of glucose. The biosensor showed a good suppression of inter- ference and a negligible deviation in the amperometric detection.

    We present the Fermi Gamma-ray Burst Monitor (GBM) and Large Area Telescope (LAT) observations of the LIGO binary black hole merger event GW151226 and candi- date LVT151012. No candidate electromagnetic counterparts were detected by either the GBM or LAT. We present a detailed analysis of the GBM and LAT data over a range of timescales from seconds to years, using automated pipelines and new techniques for char- acterizing the upper limits across a large area of the sky. Due to the partial GBM and LAT coverage of the large LIGO localization regions at the trigger times for both events, dif- ferences in source distances and masses, as well as the uncertain degree to which emission from these sources could be beamed, these non-detections cannot be used to constrain the variety of theoretical models recently applied to explain the candidate GBM counterpart to GW150914.

    戚兴国; 随志磊; 邓宇航; 代如成; 王中平; 张增明; 丁泽军


    Yb3+ and Er3+ co-doped BaBi4Ti4O15 (BBT) ceramic samples showed brighter up-conversion photoluminescence (UC-PL) under excitation of 980 nm. The monotonous increase of fluorescence intensity ratio (FIR) from 525 to 550 nm with temperature showed that this material could be used for temperature sensing with the maximum sensitivity to be 0.0046 K-1 and the energy dif-ference was 700 cm-1. Moreover, the sudden change of red and green emissions around 400 ºC might imply a phase transition. With increasing pressure up to 4 GPa, the PL intensity decreased but was still strong enough. These results illustrated the wide applications of BBT in high temperature and high pressure conditions.

  20. Prediction of saturated liquid enthalpy of refrigerant mixtures


    New corresponding temperature and corresponding enthalpy of refrigerant mix- tures were defined. The relationship between saturated liquid corresponding en- thalpy and corresponding temperature of refrigerant mixtures accorded with that of pure components. The characteristic parameters of saturated liquid enthalpy dif- ference of refrigerant mixtures were calculated by three methods according to the different application conditions. The generalized equation of saturated liquid en- thalpy of refrigerant mixtures was presented. The calculated values were compared with the values in literature for five ternary and binary refrigerant mixtures, namely R404A, R407A, R407B, R32/R134a, and R410A. The overall average absolute devia- tion was less than 1.0%.

  1. Delay Estimates of Mixed Traffic Flow at Signalized Intersections in China

    SU Yuelong; WEI Zheng; CHENG Sihan; YAO Danya; ZHANG Yi; LI Li


    Two characteristics of Chinese mixed traffic invalidate the conventional queuing delay estimates for western countries. First, the driving characteristics of Chinese drivers lead to different delays even though the other conditions are the same. Second, urban traffic flow in China is often hindered by pedestrians at intersections, such that imported intelligent traffic control systems do not work appropriately. Typical delay estimates for Chinese conditions were obtained from data for over 500 vehicle queues in Beijing collected using charge coupled device (CCD) cameras. The results show that the delays mainly depend on the pro-portion and positions of heavy vehicles in the queue, as well as the start-up situations (with or without inter-ference). A simplified delay estimation model considers vehicle types and positions that compares well with the observed traffic delays.

    The ecosystem of the Three Gorges in the Yangtze River was changed into an artificial lake (res-ervoir) ecosystem after impoundment in June 2003. We surveyed the seasonal variation and spatial distribution of copepods from April 2004 to January 2005 in order to provide data for clarifying the successional pattern of the ecosystem. From Jiangjin to Maoping, eight copepod species were collected and classified into Calanoida (2), Harpacticoida (1), and Cyclopoida (5). Among them, Mesocyclops pehpeiensis, M. leuckarti and Sinocalanus dorrii had a relatively wide distribution. No distinct dif-ference in species number was found among the sampling sites, but the species composition was different. Species composition, distribution and density of copepods showed significant seasonal variations. In addition, cope-pod density showed an obvious gradient with the distance from the reservoir dam: the nearer to the dam, the denser the copepods.

  4. Collembola feeding habits and niche specialization in agricultural grasslands of different composition

    Sechi, Valentina; D ’ Annibale, Alessandra; Ambus, Per


    The introduction of white clover in grassland is a common practice to improve the quality of the pasture and to limit the use of industrial sources of inorganic fertilizer N inputs. However, little is known about the extent to which the introduction of different crop compositions affects soil...... C of Collembola groups and the FA- d 13 C signatures of potential food sources (plant material and soil microorganisms) were calculated to explore trophic links in the three cropping combinations. Collembola showed dif- ference in FA compositions between groups. We observed a lower amount of neutral...... differences in the food sources used depending on the crop composition. Apparently, Isotoma spp. and L. cyaneus fed on clover-related diet in clover plots and more on grass-related diet in mixture treatments while Poduromorpha fed more on a plant-related diet, such as leaf litter, in the mixture treatment...

    Coupled system of multilayer dynamics of fluids in porous media is to describe the history of oil-gas transport and accumulation in basin evolution. It is of great value in rational evaluation of prospecting and exploiting oil-gas resources. The mathematical model can be described as a coupled system of nonlinear partial differential equations with moving boundary values. The upwind finite difference schemes applicable to parallel arith- metic are put forward and two-dimensional and three-dimensional schemes are used to form a complete set. Some techniques, such as change of variables, calculus of variations, multiplicative commutation rule of difference operators, decomposition of high order dif- ference operators and prior estimates, are adopted. The estimates in 12 norm are derived to determine the error in the approximate solution. This method was already applied to the numerical simulation of migration-accumulation of oil resources.

  9. Modelling Virtual Camera Behaviour Through Player Gaze

    Picardi, Andrea; Burelli, Paolo; Yannakakis, Georgios N.


    In a three-dimensional virtual environment, aspects such as narrative and interaction largely depend on the placement and animation of the virtual camera. Therefore, virtual camera control plays a critical role in player experience and, thereby, in the overall quality of a computer game. Both game...... industry and game AI research focus on the devel- opment of increasingly sophisticated systems to automate the control of the virtual camera integrating artificial intel- ligence algorithms within physical simulations. However, in both industry and academia little research has been carried out...... on the relationship between virtual camera, game-play and player behaviour. We run a game user experiment to shed some light on this relationship and identify relevant dif- ferences between camera behaviours through different game sessions, playing behaviours and player gaze patterns.

  12. [History of Smallpox Vaccination and of the Vaccine Supply in Hungary, up to 1890].

    Kiss, László


    One of the preconditions for the spread of vaccination against pox diseases was making vaccination available. The first vaccinations were carried out using original cowpox lymph sent by Jenner. For further vaccinations the vaccine was extracted from the blisters of those who had been successfully inoculated. In order to provide vaccine continuously six vaccine centres were set up in 1804 in the following cities: Pest, Buda, Kassa, Gyula, Pozsony and Zágráb (Croatia). Detailed information is available only about the centre in Pest which operated in Rókus Hospital under the leadership of the hospital director András Bossányi. Besides regular vaccination they also provided vaccine for the countryside. From 1824 the vaccine was relocated to the medical faculty of the university in Pest and Ferenc Gebhardt, an instructor of surgeons, became its head. The centre operated in the building of the medical faculty and vaccinations were given on Thursdays and Sundays. After the retirement of Gebhardt in 1860, the centre was taken over by the dermatologist Ferenc Poor for a short time, then by Ignác Semmelweis. From 1863 Gergely Patrubány was responsible for managing the centre. In 1874 the central vaccine institution moved to the Hospital for Poor Children in Pest where it was led first by Lázár Wittman, then by Géza Hainiss. In the 1880s private institutions appeared, the best known were Dani Pécsi's centre in Pest and Béla Intze's one in Tirgu Lapus (Romania). Between 1873 an 1889 András Kreichel ran a vaccine centre in Nálepkovo (Slovakia).

    The results of statistical analysis show that room rates of cheap hotels in Nanjing have a great dif-ference in the off-season.Competitive strategy and location of enterprises are main factors that lead to price dif-ference.The impact of brand type of cheap hotels on room rates is not significant.Because price competition strategy and non-price competition strategy coexist,room rates of cheap hotels in Nanjing polarize the high and low.The impact of location of cheap hotels on room rates is mirror,but it is statistically significant.Convenient public transport of Nanjing City may be the cause of this fact.%统计分析结果表明,在旅游淡季,南京市经济型酒店客房价格相差悬殊。企业竞争策略、地段是导致客房价格差异的主要因素。酒店品牌类型对客房价格没有显著影响。非价格竞争策略、价格竞争策略并存使南京市经济型酒店客房价格呈现高、低两级分化。经济型酒店所处地段对其客房价格的影响在统计上是显著的,但影响程度较小,其中的原因可能是南京市公共交通比较便捷。

  14. SBIR Grant:No-Vibration Agile Cryogenic Optical Refrigerator

    Epstein, Richard


    Optical refrigeration is currently the only all-solid-state cryocooling technology that has been demonstrated. Optical cryocoolers are devices that use laser light to cool small crystal or glass cooling elements. The cooling element absorbs the laser light and reradiates it at higher energy, an example of anti-Stokes fluorescence. The dif-ference between the energy of the outgoing and incoming light comes from the thermal energy of the cooling element, which in turn becomes colder. Entitled No-Vibration Agile Cryocoolers using Optical Refrigeration, this Phase I proposal directly addressed the continued development of the optical refrigerator components necessary to transition this scientific breakthrough into National Nu-clear Security Administration (NNSA) sensor applications in line with the objectives of topic 50b. ThermoDynamic Films LLC (TDF), in collaboration with the University of New Mexico (UNM), cooled an optical-refrigerator cooling element comprised of an ytterbium-doped yttrium lithium fluoride (Yb:YLF) crystal from room tempera-ture to 123 K with about 2% efficiency. This is the world record in optical refrigera-tion and an important step toward revolutionizing cryogenic systems for sensor ap-plications. During this period, they also designed and analyzed the crucial elements of a prototype optical refrigerator including the thermal link that connects the cool-ing element with the load.

  15. Protein identification and mRNA analysis of phyto- chrome-regulated genes in Arabidopsis under red light


    Phytochromes are a family of plant photoreceptors that mediate physiological and developmental re- sponses to red and far-red light. According to the affymetrix ATH1 microarray, phytochrome A (phyA) and phytochrome B (phyB) together play a key role in transducing the Rc signals to light-responsive genes. In order to select those red light-responsive genes associated with phyA or phyB, a proteomic approach based on two-dimensional gel electrophoresis (2-DE) was used to compare the protein ex- pression patterns of the phyAphyB double mutant and the wild type of Arabidopsis thaliana (col-4) which grew under constant red light conditions for 7 d. Thirty-two protein spots which exhibited dif- ferences in protein abundance were identified by matrix-assisted laser desorption/ionization-time of flight/time of flight mass spectrometry. The expression of ten genes corresponding to ten protein spots was analyzed by a semiquantitative reverse transcription-polymerase chain reaction. Two of the ten genes were confirmed by quantitative PCR (Q-PCR). The results showed that phytochromes may exert their function by regulating mRNA or protein expressions. Proteomic analysis may provide a novel pathway for identifying phytochrome-dependent genes.

    Objective To study the relationship between the spontaneous nocturnal episodes of alkalinization and the autonomic nerve system function and vagal function. Methods 24-hour intragastric pH was measured and auto nomic and vagal function was measured with the time domain analyses of heart rate variability in 20 patients with functional dyspepsia but without diseases of the cardiovascular system. Results 13 of 20 had the nocturnal episodes of alkalinization. The total 24-hour SDNN and rMSSD were normal in 20 subjects with FD. There was no significant dif ference (P >0. 05) in the comparison of the total SDNN and rMSSD of the 2 groups with alkalinization and without alkalinization. The 2 groups both had higher PNN50s in the nocturnal time, and there was no significant difference (P >0. 05). Conclusion The results suggest that the total autonomic nerve function and vagal function of patients with FD are normal, vagal activities of the 2 groups are both increased in the nocturnal period. The reason for the nocturnal episodes of alkalinization is not a decrease of vagal activity with a subsequent decrease of secretion.

  18. Newer treatments for decompensated heart failure: focus on levosimendan

    Ferenc Follath


    Full Text Available Ferenc FollathUniversity Hospital Zürich, Steering Group Drug Therapy, Zürich, SwitzerlandAbstract: Acute heart failure (AHF is a major cause of hospitalizations. Severe dyspnea, pulmonary congestion and low cardiac output with peripheral vasoconstriction and renal hypoperfusion is a main form of clinical presentation. Most patients with acute worsening have a pre-existing decompensated chronic heart failure (ADCHF, but AHF may also occur as a first manifestation of a previously unknown heart disease. Myocardial ischemia, cardiac arrhythmias, non-compliance with medication and infections are frequent precipitating factors. Management of AHF depends on the underlying heart disease and cause of decompensation. In patients with ADCHF vasodilators and iv diuretics are first-line drugs for rapid reduction of dyspnea and congestion. In patients with signs of low cardiac output and oliguria, inotropic agents are also often administered to prevent further deterioration. Beta-adrenergic agents and phosphodiesterase inhibitors correct the hemodynamic disturbance, but may also induce arrhythmias and worsen myocardial ischemia. Inotropic therapy therefore remains controversial. A novel class of drugs, the calcium sensitizers, represent a new therapeutic option. Levosimendan was shown to improve myocardial contractility without increasing oxygen requirements and to produce peripheral and coronary vasodilation. Its therapeutic effects and tolerance have been tested in several trials. The present review focuses on the clinical pharmacology and therapeutic utility of levosimendan in patients with ADCHF.Keywords: acute heart failure, inotropic agents, calcium sensitizers, levosimendan

  19. Adenovirus-mediated Transfer of p53 and p16 Inhibiting Proliferating Activity of Human Bladder Cancer Cell EJ in vitro and in vivo

    朱朝辉; 邢诗安; 林晨; 曾甫清; 鲁功成; 付明; 张雪艳; 梁萧; 吴旻


    Summary: To evaluate the effects of adenovirus (Ad)-mediated transfer of p53 and p16 on humanbladder cancer cells EJ, EJ were transfected with Ad-p53 and Ad-p16. Cell growth, morphologi-cal change, cell cycle, apoptosis were measured using MTT assay, flow gytometry, cloning forma-tion, immunocytochemical assays. Ad-p16 or Ad-p53 alone could inhibit the proliferating activityof EJ cells in vitro. Ad-p53 could induce apoptosis of partial EJ cells. G1 arrest was observed 72 hafter infection with Ad-p16, but apoptosis was not obvious. The transfer of Ad-p16 and Ad-p53could significantly inhibit the growth of EJ cells, decrease the cloning formation rate and induceapoptosis of large number of EJ cells. The occurrence time of subcutaneous tumor was delayed andthe tumor volume in 4 weeks was diminished by using Ad-p53 combined with Ad-p16 and the dif-ference was significant compared with using Ad-p53 or Ad-p16 alone. It was suggested that thetransfer of wild-type p53 and p16 could significantly inhibit the growth of human bladder cancer invitro and in vivo.

    Full Text Available Production values of 43 experimental and recognized sugar beet hybrids were conducted on the Zagreb location in the period 2003-2005. The trials included hybrids from six breeding institutions that sell sugar beet seed in the Republic of Croatia. Research results have revealed significant differences in yields and root quality among inve- stigated sugar beet hybrids. However, the results of a large number of hybrids were equal in value; namely, the dif- ference between them was within the statistically allowable deviation. The hybrids KW 0148 HR and Buda in 2003, Sofarizo and Takt were distinguished by high sugar yields in 2004, whereas Merak, Impact and Europa in 2005. The highest root yields were recorded for hybrids Dioneta, Buda and KW 0148 HR in 2003, Sofarizo, Takt, HI 0191 and Dorotea in 2004, Impact and SES 2371 in 2005. The highest root sugar contents were determined in hybrids Zita and Evelina in 2003, Cyntia, Diamant and Belinda in 2004, and Merak, Belinda and Cyntia in 2005.

    CHEN Jian-bo; CHEN Dan; LU Ying


    Energy-saving air-conditioner with hot water is an air source heat pump air-conditioner,which can also supply hot water.The hot water is heated by a double pipe condenser connected with an air-cooled condenser in series in the system.This experiment of the energy-saving air-conditioner was carried out in the enthalpy-dif-ference air-conditioner laboratory.The hot water temperature and the compressor'S discharge and suction pres.sure were recorded in the working condition,where the ambient temperature was at 43℃,35℃,21℃,7℃,and 2℃separately.The results showed that the system operated stably and reliably. This system can supply 240 L hot water at 50℃in the whole year,and its coefficience of performance(COP)is much higher than the conventional air source heat pump system.Its energy conservation WaS proved by comparing the thermal effi.ciency with other sourece water heaters.

  4. Design of Optical Tunable CNOT (XOR) and XNOR Logic Gates Based on 2D-Photonic Crystal Cavity Using Electro-Optic Effect

    Abbasian, Karim; Sadeghi, Parvin


    We have proposed optical tunable CNOT (XOR) and XNOR logic gates using two-dimensional photonic crystal (2DPhC) cavities. Where, air rods with square lattice array have been embedded in Ag-Polymer substrate with refractive index of 1.59. In this work, we have enhanced speed of logic gates by applying two input signals with a phase dif?ference at the same wavelength for 2DPhC cavities. Where, we have adjusted the phases of input and control signals equal with {\\pi}/3 and zero, respectively. The response time of the structure and quality factor of the cavities are in the range of femtosecond and 2000, respectively. Then, we have used electro-optic property of the substrate material to change the cavities resonance wavelengths. By this means, we could design the logic gates and demonstrate a tunable range of 23nm for their operation wavelength. The quality factor and the response times of cavities remain constant in the tunable range of wavelength, approximately. The evaluated least ON to OFF logic-level contras...

  6. 15th International Conference on Thermal Conductivity


    Once again, it gives me a great pleasure to pen the Foreword to the Proceedings of the 15th International Conference on Thermal Conductivity. As in the past, these now biannual conferences pro­ vide a broadly based forum for those researchers actively working on this important property of matter to convene on a regular basis to exchange their experiences and report their findings. As it is apparent from the Table of Contents, the 15th Conference represents perhaps the broadest coverage of subject areas to date. This is indicative of the times as the boundaries between disciplines be­ come increasingly diffused. I am sure the time has come when Con­ ference Chairmen in coming years will be soliciting contributions not only in the physical sciences and engineering', but will actively seek contributions from the earth sciences and life sciences as well. Indeed, the thermal conductivity and related properties of geological and biological materials are becoming of increasing im­ portance to our way of life. As...

  10. The Hungarian Peculiarities of National Remembrance: Historical Figures with Symbolic Importance in Nineteenth-century Hungarian History Paintings

    Zsuzsanna Tóth


    Full Text Available In order to place nineteenth-century Hungarian art into international context, this article calls for the theoretical discourse of cultural memory, when a suppressed community turns to their past and insists on their antecedents’ traditions for the survival of their culture. When, in the 1850s and 1860s, the leaders of the Habsburg Austrian Empire retaliated against Hungary for its 1848-49 “Fight for Freedom”, Hungarian visual art of the era rediscovered long-honoured figures of the historical past as the essential components of Hungarian national identity. This article argues that the successful visualization and memorialization of outstanding historical characters with symbolic values for the Hungarian nation was due to history painting itself as medium. The Hungarian painters’ choice of characters vigorously reacted to the changing political relationship between the Austrians and the Hungarians from the failure of the 1849 Hungarian Fight for Freedom until the 1850s and the 1870s involving the 1867 Austro-Hungarian Compromise. Keeping it in mind, the display and the reception of four great paintings, Bertalan Székely’s The Discovery of the Body of King Louis II (1860, Viktor Madarász’s Péter Zrínyi and Ferenc Frangepán in Prison at Wiener-Neustadt (1864, Székely’s The Women of Eger (1867 and Gyula Benczúr’s The Baptism of Vajk (1875 are analysed.

  11. [Once upon a time there was a medical faculty--a brief history of the Medical Faculty of the Erzsébet University in Pressburg (1914-1919)].

    Kiss, László


    Despite the fact that the idea of expanding the medical faculties of Budapest and Kolozsvár was formed in the 1870s, it only came true in the 1910s. The XXXVI. Law of 1912 ensured establishing new faculties in Pozsony and Debrecen. The medical faculty of Erzsébet University in Pozsony opened in 1914. The first three professors, i.e. Lajos Bakay, Ferenc Herzog and Dezső Velits, who formerly worked as head physicians for the State Hospital in Pozsony and the Institute for Midwives, were appointed then. The appointment of further professors and launching the 3rd, 4th and 5th forms were delayed by the outbreak of the war until 1918. After the collapse of the Austro-Hungarian Monarchy the newly formed Czechoslovakia dissolved the Hungarian university in 1919. The clinics and institutes of the medical faculty were passed to Czechoslovak ownership, the Hungarian lecturers were dismissed. It is worth mentioning though that Albert Szent-Györgyi and Carl Ferdinand Cori (both Nobel Prize winners) started their scientific career in Pozsony.

  14. Parameter estimation and hypothesis testing in linear models

    Koch, Karl-Rudolf


    The necessity to publish the second edition of this book arose when its third German edition had just been published. This second English edition is there­ fore a translation of the third German edition of Parameter Estimation and Hypothesis Testing in Linear Models, published in 1997. It differs from the first English edition by the addition of a new chapter on robust estimation of parameters and the deletion of the section on discriminant analysis, which has been more completely dealt with by the author in the book Bayesian In­ ference with Geodetic Applications, Springer-Verlag, Berlin Heidelberg New York, 1990. Smaller additions and deletions have been incorporated, to im­ prove the text, to point out new developments or to eliminate errors which became apparent. A few examples have been also added. I thank Springer-Verlag for publishing this second edition and for the assistance in checking the translation, although the responsibility of errors remains with the author.

    ZHOU WeiHong; SHEN YueQuan; QIN XiaoHong; YAN XiaoJie; XIE XingQiao; LI Liang; FANG ShaSha; LONG JiaFu; ADELMAN John; TANG Wei-Jen


    Protein kinase CK2 consists of two catalytic subunits (CK2α) and two regulatory subunits (CK2β). Here,we report the crystal structures of rat CK2α mutant (rCK2α-△C, 1-335) and CK2β(rCK2β). The overall topology of rCK2α-△C and rCK2βare very similar to the human enzyme, although large structural dif-ferences could be observed in the N-terminal domain of rCK2α-△C. Our reported structure of rCK2α-△C is in the close conformation state while the counterpart hCK2α is in the open conformation state, indi-cating the conformation of CK2α molecule has high plasticity. The structure of rCK2β represents the conformation of free CK2β. Upon CK2α binding, the C-terminal region undergoes a drastic conforma-tional change. The major region of interaction within the interface of CK2αCK2β may serve as a bridge to transmit the conformational change and thus regulate the activity of CK2α.

    Hadi Ghasemi


    Full Text Available Objectives: Smoking may impact oral self-care (OSC.  This study aimed to analyze the role of smoking in OSC among Iranian dental health professionals.Materials and Methods: The cross-sectional data were collected at two annual dental meetings and seven randomly selected dental schools in Iran. A total of 1,459 respond- ents composed of 967 general dental practitioners (GDPs, 229 dental educators (DE, and 263 senior dental students (DS anonymously completed a self-administered ques- tionnaire inquiring about smoking status and OSC.Results: Thirty percent of the men and 12% of women reported smoking with no dif-ference according to their professional status. Women reported better OSC than did men, but only 26% of the women and 17% of the men followed the three most important recommendations for OSC. Smoking was associated with infrequent tooth brushing and flossing, irregular use of fluoride containing toothpaste, consumption of sugary snacks, and weak adherence to the recommended OSC guidelines.Conclusion: Dental health education should place more emphasis on smoking counsel-ing and cessation among dental health professionals.

  20. Precision in the measurement of dairy feed fractions based on particle size.

    Mauro Spanghero


    Full Text Available The aim of this research note is to evaluate the variability of the physical measurements obtained by a separator of feeds  for dairy cows based on particle size. Fresh samples of total mixed ration (TMR and corn silage were collected from four  dairy units and were immediately fractionated using a particle separator (NASCO®, Pennsylvania State University com-  posed of two sieves (diameters of 19 and 8 mm and a collector on the bottom. Repeatability expressed as standard devi-  ation was similar between fractions (>19, 8-19 and   +1.7 and +1.5% for corn silages, but when expressed as coefficient of variation there were, for both samples, large dif-  ferences between the values for fraction exceeding 19 mm (44.7 and 35.1 %, respectively for TMR and corn silages and  the middle (3.9 and 2.5 %, respectively for TMR and corn silages and bottom fractions (3.7 and 5.6 %, respectively for  TMR and corn silages. The between operator reproducibility was very close to repeatability and this indicates that the  operator’s contribution to the overall variability is marginal in comparison with residual variability. In conclusion, differ-  ent operators properly trained in the use of the NASCO® separator can produce satisfactory repeatable and reproducible  values for the middle and the bottom fractions.

  6. On two transverse nonlinear models of axially moving beams


    Nonlinear models of transverse vibration of axially moving beams are computationally investigated. A partial-differential equation is derived from the governing equation of coupled planar motion by omit- ting its longitudinal terms. The model can be reduced to an integro-partial-differential equation by av- eraging the beam disturbed tension. Numerical schemes are respectively presented for the governing equations of coupled planar and the two governing equations of transverse motion via the finite dif- ference method and differential quadrature method under the fixed boundary and the simple support boundary. A steel beam and a copper beam are treated as examples to demonstrate the deviations of the solutions to the two transverse equations from the solution to the coupled equation. The numerical results indicate that the differences increase with the amplitude of vibration and the axial speed. Both models yield almost the same precision results for small amplitude vibration and the inte- gro-partial-differential equation gives better results for large amplitude vibration.

    Partial least-squares (PLS) regression has been presented as a powerful tool for spectral quantitative measure- ment. However, the improvement of the robustness and stability of PLS models is still needed, because it is difficult to build a stable model when complex samples are analyzed or outliers are contained in the calibration data set. To achieve the purpose, a robust ensemble PLS technique based on probability resampling was proposed, which is named RE-PLS. In the proposed method, a probability is firstly obtained for each calibration sample from its resid- ual in a robust regression. Then, multiple PLS models are constructed based on probability resampling. At last, the multiple PLS models are used to predict unknown samples by taking the average of the predictions from the multi- ple models as final prediction result. To validate the effectiveness and universality of the proposed method, it was applied to two different sets of NIR spectra. The results show that RE-PLS can not only effectively avoid the inter- ference of outliers but also enhance the precision of prediction and the stability of PLS regression. Thus, it may pro- vide a useful tool for multivariate calibration with multiple outliers.

  11. Reliability design method for steam turbine blades

    Jinyuan SHI


    Based on theories of probability and statistics, and taking static stresses, dynamic stresses, endurance strength, safety ratios, vibration frequencies and exciting force frequencies of blades as random variables, a reliabil-ity design method for steam turbine blades is presented. The purport and calculation method for blade reliability are expounded. The distribution parameters of random variables are determined after analysis and numerical cal-culation of test data. The fatigue strength and the vibra-tion design reliability of turbine blades are determined with the aid of a probabilistic design method and by inter-ference models for stress distribution and strength distri-bution. Some blade reliability design calculation formulas for a dynamic stress design method, a safety ratio design method for fatigue strength, and a vibration reliability design method for the first and second types of tuned blades and a packet of blades on a disk connected closely, are given together with some practical examples. With these methods, the design reliability of steam turbine blades can be guaranteed in the design stage. This research may provide some scientific basis for reliability design of steam turbine blades.

    Diffusion-tensor imaging can be used to observe the microstructure of brain tissue. Fractional sotropy reflects the integrity of white matter fibers. Fractional anisotropy of a young adult brain is low in gray matter, high in white matter, and highest in the splenium of the corpus cal osum. Thus, we selected the anterior and posterior limbs of the internal capsule, head of the caudate nucleus, se-mioval center, thalamus, and corpus cal osum (splenium and genu) as regions of interest when using diffusion-tensor imaging to observe fractional anisotropy of major white matter fiber tracts and the deep gray matter of healthy rhesus monkeys aged 4-8 years. Results showed no laterality ferences in fractional anisotropy values. Fractional anisotropy values were low in the head of date nucleus and thalamus in gray matter. Fractional anisotropy values were highest in the sple-nium of corpus cal osum in the white matter, fol owed by genu of the corpus cal osum and the posterior limb of the internal capsule. Fractional anisotropy values were lowest in the semioval center and posterior limb of internal capsule. These results suggest that fractional anisotropy values in major white matter fibers and the deep gray matter of 4-8-year-old rhesus monkeys are similar to those of healthy young people.

  15. REE Geochemical Characteristics of Tungsten Minerals as a Discriminant Indicator of Genetic Types of Ore Deposits

    张玉学; 刘文茂; 等


    Tungsten minerals (scheelite and wolframite)from two genetic types of granitoids show significant dif-ferences in REE distribution,probably due to different material sources and origins.Tungsten miner-als in granite porphyry of the crust-mantle source are relatively high in ∑REE(1884ppm on average).∑ Ce is rich relative to ∑Y and ∑Ce/∑Y is relatively high(>1).The chondrite-normalized REE distribution patterns are characterized by a group of rightward-inclined curves.Tungsten minerals in quartz veins intruding the granites of crust origin have lower ∑REE (335 ppm on average).∑Y is rich relative to ∑Ce and ∑Ce/∑Y is relatively low(<1).The chondrite-normalized REE distribution patterns are characterized by a group of leftward-inclined curves.So the REE distribution patterns can be used to discriminate the sources of rock-and ore-forming materials and the genetic types of W deposits so as to provide clues to ore prospecting.

  16. Preliminary analysis on the relationships between Tibetan Plateau NDVI change and its surface heat source and precipitation of China


    Using the automatic weather station data obtained from the Tibetan Plateau (TP), the normalized dif- ference vegetation index and the monthly precipitation data of China and by the methods of correlation and composite analysis, preliminary analytical results are achieved concerning the relationships be- tween TP NDVI change and its surface heat source and precipitation of China. The results of our re- search may lead to the following conclusions: (1) A positive correlation relationship exists between TP NDVI change and its surface heat source, including the sensible heat and the latent heat. As to the correlation of the former, it is more remarkable in western TP than in eastern TP, and as to the correla- tion of the latter, however it turns out contrary. (2) With the improvement of TP vegetation, its surface heat source of every season is also mainly reinforced, especially in summer. As to the contribution of the sensible heat and the latent heat to the increment of the TP surface heat source intensity, the for- mer is comparatively more significant than the latter in winter and spring, while in summer and autumn, the two have almost the same importance. (3) The correlation coefficient between summer NDVI over TP and the corresponding period precipitation of China displays a belt distribution of "+?+" from south to north China. (4) Anomalous surface heating field over TP derived from vegetation change is probably an important factor to affect summer precipitation of China.

    Makarenko, M V; Lyzohub, V S; Iukhymenko, L I; Khomenko, S M


    The peculiarities of the heart rhythm regulation were investigated in humans during the processing of acoustic information. Statistically significant differences were found in individuals with different levels of auditory-motor reactions according to the heart rhythm characteristics. Individuals with the high level of reactions were characterized by significantly lower total power spectrum (TP=1276.2 ms2), by the power spectrum of high (HL=280.1 ms12) and very low frequencies (VLF-469.8 ms2), as well as by low indexes of standard deviation of R-R intervals (SDNN=37.4 ms), when compared with the persons with the low level of reactions (5248.8; 866.7; 1937.0; 69.8 ms2). The correlation analysis confirmed the dif- ferences between the groups ol persons with adtierent number of processed information and variable (r=0.41, P<0.05) and spectral characteristics of heart rate (r=-0.49--0.56, P<0.05). Different strategies of activation of non-specific brain systems in formation of psycho-physiological reactions and participation of heart rhythm regulatory mechanisms in vegetative support of auditory information processing are discussed.

  1. Development of single-chip fuzzy controller based on FFSI in binary

    张吉礼; 欧进萍; 孙德兴


    Length and concise structure of fuzzy logic reasoning program and its real-time reasoning characteris-tic have their effect on the performance of a digital single-chip fuzzy controller. The control effect of a digitalfuzzy controller based on looking up fuzzy control responding table is only relative to the table and not relative tothe fuzzy control rules in the practical control process. Aiming at above problem and having combined fuzzy log-ic reasoning with digital operational characteristics of a single-chip microcomputer, functioning-fuzzy-subset in-ference (FFSI) in binary, in which triangle membership functions of error and error-in-change are all represen-ted in binary and singleton membership functions of control variable is binary too, has been introduced. The cir-cuit principle plans of a single-chip fuzzy controller have been introduced for development of its hardware, andthe primary program structure, fuzzy logic reasoning subroutine, serial communication subroutine with PC andreliability design of the fuzzy controller are all discussed in detail. The control of indoor temperature by a fuzzycontroller has been conducted using a testing-room thermodynamic system. Research results show that the FFSIin binary can exercise a concise fuzzy control in a single-chip fuzzy controller, and the fuzzy controller is there-fore reliable and possesses a high performance-price ratio.

  4. Work–Family Interference: Nurses in Norway and Finland

    Bente Abrahamsen


    Full Text Available Abstract The aim of the study is to investigate the level of work–family inter-ference (WFI for part-time nurses in Norway and Finland. Part-time work is usually cited as a desirable way in which to facilitate work and family harmony. However, the opportunity to work part-time in professions may be associated with greater difficulties and challenges than commonly presumed. Part-time professionals are often stigmatized as being less committed to work and report fewer job rewards than colleagues in full-time positions. This study challenges the notion of the desir-able consequences of work hour flexibility concerning the integration of work and family. Part-time nurses in Norway and Finland report an equal level or even higher levels of interference than nurses in full-time positions. A disproportional distri-bution of inconvenient work schedules appears to be a central explanation for the results reported by Norwegian nurses, but to a lesser degree by Finnish nurses.

  5. A new capacitive borehole tiltmeter for crustal deformation measurement and its performance analysis

    Wu Liheng; Li Tao; Chen Zheng; Li Hong


    Borehole inclinometers are important observation instruments used to measure ground tilt movement and monitor crustal deformation of solid tides and geological landslide disasters. They are widely used in oil exploration, mineral resource drilling, well logging, exploration and other fields. There is potential for development of rock stress strain monitoring tools. Many types of tiltmeters have been installed, such as SQ-7, FSQ, VS and JB. However, these tiltmeters are generally installed in a deep cave to avoid the inter-ference of temperature, humidity, and human activities. With the urbanization of human society, suitable installation locations are difficult to find. To solve the problem, a two-component borehole tiltmeter, named the CBT-type tiltmeter, is proposed in this paper. It can be installed in a borehole less than 500 m deep to eliminate environmental influences. The tiltmeter is composed of two sophisticated gravitational swing and two capacitive transducers. From preliminary theory and experiment analysis, its linear correlation coefficient is higher than 0.99, its co-seismic response is rapid and its noise level is up to 10-4 arc seconds in practice.

    杜海燕; 杨立娜; 高婉琪; 刘家臣


    The properties of two types of fly ash geopolymers made from class F fly ashes produced in wet bottom and dry bottom boilers were investigated in the present study. The source material used in the geopolymer concrete was activated with sodium hydroxide and sodium silicate solution. The results revealed that the geopolymer pro-duced with wet bottom boiler fly ash(CZ-FA)hardened quickly, and had higher early-age strength and lower shrinkage than the geopolymer produced with dry bottom boiler fly ash(SX-FA). The compressive strength of the two geopolymers made from CZ-FA and SX-FA was 45 MPa and 15 MPa respectively when cured at 60℃ and delayed for 14 d. However, after 90 days’ delay, the compressive strength of both the samples is almost the same, up to 80 MPa. Nearly 20% volume shrinkage of the samples made from SX-FA was much higher than that made from CZ-FA, which was almost zero. XRD, SEM/EDS and FT-IR were used to analyze the main reason of the dif-ferences.

    Shiming WANG; Peng DAI; Jun XU; Zheng YANG


    In order to study the effect of self-made liver preservation solution on liver preservation by comparing with UW solution and HC-A solution, the self-made liver preservation solution (SM) and perfusion solution were prepared under the aseptic conditions. The isolated non-circulated perfu-sion rat liver model was established. According to the different preservation solutions, the rats were randomly divided into UW group, SM group and HC-A group. The three groups were divided into 6subgroups according to the preservation duration (n=6 in each group). The transferase in liver perfu-sion solution and intercellular adhesion molecule-1 (ICAM-1) and nitric oxide (NO) in liver tissues were determined at 2, 8 and 24 h respectively. The results showed that the levels of alanine aml- notransferase (ALT) and aspartate aminotransferase (AST) had no significant difference between SM group and UW group, but significantly lower than in HC-A group. The levels of ICAM-1 and NO were increased simultaneously in SM group and UW group (P>0.05), but there was significant dif-ference as compared with HC-A group (P<0.05). At the same time point, the level of ICAM-1 was higher in SM group than in UW group, but NO was lower. The preservation effect of SM solution is the same as UW solution, but better than HC-A solution.

  10. On the Capacity of the Interference Channel with a Cognitive Relay

    Rini, Stefano; Devroye, Natasha; Goldsmith, Andrea


    The InterFerence Channel with a Cognitive Relay (IFC-CR) consists of the classical interference channel with two independent source-destination pairs whose communication is aided by an additional node, referred to as the cognitive relay, that has a priori knowledge of both sources' messages. This a priori message knowledge is termed cognition and idealizes the relay learning the messages of the two sources from their transmissions over a wireless channel. This paper presents new inner and outer bounds for the capacity region of the general memoryless IFC-CR that are shown to be tight for a certain class of channels. The new outer bound follows from arguments originally devised for broadcast channels among which Sato's observation that the capacity region of channels with non-cooperative receivers only depends on the channel output conditional marginal distributions. The new inner bound is shown to include all previously proposed coding schemes and it is thus the largest known achievable rate region to date. T...

The Nei's genetic distances were 0.000 59 between two populations. The result of chi-square test of the GPI gene in two populations showed that their genetic structure has very significant dif- ference. [Conclusion] This study provided a theoretical basis for large-scale extension of Jing silver carp.

  12. Antler development in reindeer in relation to age and sex

    Amund Høymork


    Full Text Available Yearling male and adult female reindeer (Rangifer tarandus tarandus are similar in size and shape. If sexual clues are hidden, it can be difficult to distinguish between them. Antlers can be a useful aid in classifying yearling males and adult females, depending on whether specific antler characteristics are identifiable for these two groups. We recorded antler characteristics in a domestic reindeer herd (Vågå and found considerable overlap in antler height, width and circumference between the different age and sex groups. Total tines and number of tine split-offs are use¬ful for the field biologist when discriminating among adult females, yearling males and 2.5 year-old males. For example, when using the tine split-offs with the suggested classification, 79% of the observed adult females and 76% of the yearling males were classified correctly. The antler height, width and circumference provide other biological dif¬ferences between groups, but are not easy to use to identify free ranging reindeer. This is due to the great overlap in antler size between the groups and measuring difficulties in a field study situation. Male and female calves have very similar antlers, and only the antler width is possible for sex discrimination, giving 67% accuracy of discriminating between these two groups.

    汪小全; 邹喻苹; 张大明; 洪德元; 刘正宇


    Genetic diversity level of Cathaya argyrophylla was confirmed by random amplified polymorphic DNA (RAPD) markers. Seventy five samples (individuals), collected from Hunan and Sichuan provinces of China were used in the study. 21 10-mer oligonucleotide primers detected 106 sites, and 34 (32% ) of them were polymor-phic. The level of genetic variation in C. argyrophylla was lower than those of other conifers, and was considered to be associated with the complexity of habitats. The percentages of polymorphic sites (PPS) in the Hunan and Sichuan pop-ulations were 18% and 25% respectively. 7.99% of genetic variation existed between the two populations; this value was higher than the mean value (6.8%) among populations in conifers displayed by allozyme. Some subpopulations of C. argyrophylla were greatly differentiated because of site mutation and genetic drift. The highest value of genetic dif-ference between subpopulations amounted to 16. 23% . In addition, a concept of diversity coefficient(DC), a value us

  15. Isospin and symmetry energy study in nuclear EOS


    This paper summarizes the isoscaling and isospin related studies in asymmetry nuclear reactions by different dynamic and sta tistical models. Isospin dependent quantum molecular dynamics model (IQMD) and lattice gas model (LGM) are used to study the isoscaling properties and isoscaling parameters dependence on incident energies, impact parameters, temperature and other parameters. In the LGM model, the signal of phase transition has been found in free neutron (proton) chemical potential dif ference Δμn or Δμp as a function of temperature, or in free neutron and proton chemical potential difference Δμn-Δμp. Density dependence of symmetry energy coefficient Csym(ρ/ρ0) is also studied in the frame of LGM, with the potential parameters which can reproduce the nuclear ground state property, soft density dependence of symmetry energy is deduced from the sim ulation results. Giant dipole resonance (GDR) induced by isospin asymmetry in entrance channel is also studied via IQMD model, and the dynamic dipole resonance shows isospin sensitivity on the isospin asymmetry of entrance channel and sym metry energy of the nuclear equation of state (EOS). GDR can also be regarded as a possible isospin sensitive signature.

    Objective: To evaluate the medicinal uses of Rhanterium epapposum Oliv. (R. epapposum) growing in northern border region of Saudi Arabia, through the chemical diversity of essential oils extracted from its flowers, leaves and stems. Methods: Aerial parts of R. epapposum were collected in April 2014. Air dried flowers, leaves, and stems were separately subjected to hydrodistillation in a Clevenger-type apparatus for 4 h to extract the essential oils. Gas chromatography-mass spectrometry analysis of the essential oils was carried out using an Agilent 6890 gas chromatograph equipped with an Agilent 5973 mass spectrometric detector. Results: A total of 51 compounds representing 76.35%–94.86%of flowers, leaves and stems oils composition were identified. The chemical profiles of the studied fractions revealed the dominance of monoterpenes, regardless of qualitative and quantitative dif-ferences observed. Limonene, linalool, 4-terpineol and a-cadinol represented the major constituents of flowers oil. Leaves oil was dominated by limonene, sabinene, a-pinene and β-myrcene whereas linalool, ionole, a-cadinol, β-eudesmol, 4-terpineol, and a-terpineol were the major constituents of stems oil. Conclusions: Essential oils from flowers, leaves and stems of R. epapposum growing in northern border region of Saudi Arabia are considered as a rich source of monoterpenes which have biological activities.

    She, Yan-Fen; Zhu, Jiang


    The meridian-acupoint has response function and effect function. As a direct reflection between acupoint and diseased area, the response function is the foundation of the effect function, and skin resistance of acupoint is usually used as an objective indice for research of meridian-acupoint response. Among the skin resistance-based researches on specificity of meridian-acupoint reaction, the selection of instrument is a key point. At present the main measurement instruments for meridian-acupoint resistance include dual-electrode device and four-electrode device. After analyzing the characteristics and inter-ference factors of different types of measurement instruments for meridian-acupoint resistance, dual-electrode device is suitable for qualitative analysis, for its control of interference factors needs to improve. The four-electrode device is good at quantitative research, for it is easier to control interference factors. Yet, there is more for research department to do to improve the instrument design by modern scientific technique in order to meet need for research.

    Habitat plays a critical role in regulating fish community structure. Using the data collected from a monthly trammel net survey in Ma’an archipelago off the east coast of China, we evaluated impacts of five different habitats (artificial reefs, mussel farms, cage aquaculture, rocky reefs and soft bottom) on fish assemblages. This study suggests that artificial reefs (AR) have significantly higher species richness, abundance and diversity than mussel farms (MF) or soft bottom (SB) habitats during most seasons, and that fish taxa in the AR habitats are similar to those in the rocky reef (RR) habitats. Two different fish assemblage patterns were revealed in the study area using non-metric multidimensional scaling ordination: an assemblage dominated by reef fishes (especially by Scor-paenidae species) in AR, RR and cage aquaculture (CA) habitats and an assemblage dominated by Sciaenidae species in MF and SB habitats. We suggest that reef fishes play a key role in differentiating fish community structures in the study area. Although few dif-ferences in fish abundance and diversity were found between the CA and SB habitats, a more diverse age structure was observed in the CA habitats. A much more complex fish assemblage and enhanced population of local species were established as a result of the presence of both floating and fixed artificial structures, probably through improved survival rates.

    B. Yazdi


    Full Text Available Introduction & Objective: Even a little bleeding can adversely affect the surgeon's ability to visualize the region to be operated in ENT operations. The aim of this study is to compare the effects of isoflurane and sevoflurane on hemodynamics and bleeding in controlled hypoten-sion. Materials & Methods: This study was a double-blind clinical trial. Ninety patients who were candidates for endoscopic sinus surgery and tympanomastoidectomy in Amirkabir hospital of Arak were randomly assigned into two groups of isoflurane and sevoflurane. Remifentanil was infused at 0.1 µg/kg/min for both groups during surgery and the amount of bleeding and hemodynamic parameter were recorded. The data was analyzed by SPSS-20 and ANOVA statistical test. Results: Underlying and hemodynamic variables were similar between the two groups preop-eratively. The amount of blood loss during surgery showed that there were no significant dif-ferences between the two groups (P=0.802 and no significant differences in hemodynamic variables (heart rate, systolic/diastolic blood pressure and arterial oxygen saturation were observed between the two groups during the surgery. Conclusion: It is concluded that there is no difference between sevoflurane and isoflurane in controlled hypotension. Thus, using these drugs in operations with excessive bleeding is rec-ommended.

    Masashi TAKAHASHI; Shin-Ichi GOTO; Kazuhisa MORI; Izumi MATAGA


    The purpose of this study is to clarify the dif-ference of histology and elemental composition of the cer-vical enamels among the human permanent teeth. The re-ground surfaces at the cervical enamels of them were observed under scanning electron microscopy (SEM). The contents of seven elements were analyzed quantita-tively with electron probe microanalyzer (EPMA). The widths of the rod sections at the cervical enamels were larger than those at the cuspal enamels. The rod sections at the mesial cervical enamels in the incisors were more obscure and more decayed by acid solution than those in the premolars and molars. The calcium and phosphorus contents of the cervical enamels were significantly lower than those of the cuspal enamels. The carbon content of the cervical enamels was significantly higher than that of the cuspal enamels. The calcium and phosphorus contents of the cervical enamels were the significantly highest in the premolars. The carbon and sodium contents of the cer-vical enamels were significantly highest in the premolars. It is thought that the calcification level is lower, while the content of organic matter is higher at the cervical enamels than those at the cuspal enamels. It is considered that the sodium causes high calcification.

  4. APL programs for the mathematics classroom

    Thomson, Norman D


    The idea for this book grew out of proposals at the APL86 con­ ference in Manchester which led to the initiation of the I-APL (International APL) project, and through it to the availability of an interpreter which would bring the advantages of APL within the means of vast numbers of school children and their teachers. The motivation is that once school teachers have glimpsed the possibilities, there will be a place for an "ideas" book of short programs which will enable useful algorithms to be brought rapidly into classroom use, and perhaps even to be written and developed in front of the class. A scan of the contents will show how the conciseness of APL makes it possible to address a huge range of topics in a small number of pages. There is naturally a degree of idiosyncrasy in the choice of topics - the selection I have made reflects algo­ rithms which have either proved useful in real work, or which have caught my imagination as candidates for demonstrating the value of APL as a mathematical notation.

    YANG Ying; CHENG Longxian; Ripen Nsenga; HE Meian; CHANG Zhitang; WU Tangchun


    In order to investigate the association of G+1688A (Ser563Asn) polymorphism of platelet endothelial cell adhesion molecule-1 (PECAM-1) gene with myocardial infarction (MI) in the Chi- nese Han population, the G+1688A polymorphism in PECAM-1 gene was detected by polymerase chain reaction-restriction fragment-length polymorphism (PCR-RFLP) method among 502 subjects, including 218 patients with MI and 284 controls. The results showed that there was significant dif-ference in AA frequencies of genotype G+1688A polymorphism between case and control groups (39% vs 24%, P<0.001). A similar trend was observed on the allele frequencies (A/G: 62% vs 49%, P<0.001). Among the subjects with high serum total cholesterol level or high systolic blood pressure level, the variant AA genotype was associated with high risk of MI (adjusted OR, 2.13; 95% CI, 1.08-4.41 and adjusted OR, 2.53; 95%CI, 1.63-3.63). The single nucleotide polymorphism (SNP) at position +1688 in the exon 8 of PECAM-1 gene was associated with MI and the allele A might be a risk factor for MI in the Chinese Han population.

  7. Developments in Humidity Standards and the Psychrometer Equation%湿度标准及湿度计量之进展

    Ian C. Kemp; Carl-Gustav Berg


    Determination of the wet-bulb temperature at the surface of a material is the basis of one class ofhumidity measuring instruments, and is important in industrial applications such as dryer modelling and simula-tion. The psychrometer equation is a frequently used method of estimating wet-bulb temperature, and contains apsychrometer "constant". Analysis shows that this is in fact a variable coefficient affected by temperature, pressure,radiation and conduction effects, and the identity of the gas and vapour. Radiation and conduction affect the dif-ference between adiabatic saturation temperature and indicated wet-bulb temperature. Inconsistencies in currentlyrecommended values for the psychrometer coefficient, including published international standards, are identifiedand explained. Particular problems arise when the enhancement factor is applied to vapour pressure to accountfor non-ideality of gases. Special considerations are also needed for wet-bulb temperatures approaching the boilingpoint, where the psychrometer coefficient tends to zero. Self-consistent recommendations recently published in thenew British Standard BS1339 are given, which cover both the air-water system and a general vapour-gas system.

    Timotin, D; Vasilescu, F-H


    Since 1976 the Institute of Mathematics of the Romanian Academy (formerly the Department of Mathematics of INCREST) and the Faculty of Mathematics (formerly the Faculty of Sciences) of the University ofTimi~oara have organized several Con­ ferences on Operator Theory. These Conferences were held yearly in Timi~oara (or in Timi~oara and Herculane) and beginning with 1985 they were held in Bucharest (1985,1986), in Timi~oara (1988) and in Predeal (1990). At the beginning, these Conferences answered the need of a part of the Romanian Mathematical Community ofexploring other forms of survival, after the dissolution of the Institute of Mathematics in 1975. Soon, these meetings evolved to International Conferences with a broad participation and where important results in Operator Theory and Operator Algebras and their interplay with Complex Function Theory, Differential Equations, Mathematical Physics, System Theory, etc. were presented. The 14th Conference on Operator Theory was held between June 1st and June 5th...

    The refined Arnoldi method proposed by Jia is used for computing some eigen-pairs of large matrices. In contrast to the Arnoldi method, the fundamental dif-ference is that the refined method seeks certain refined Ritz vectors, which aredifferent from the Ritz vectors obtained by the Arnoldi method, from a projection space with minimal residuals to approximate the desired eigenvectors. In com-parison with the Ritz vectors, the refined Ritz vectors are guaranteed to converge theoretically and can converge much faster numerically. In this paper we propose to replace the Ritz values, obtained by the Arnoldi method with respect to a Krylovsubspace, by the ones obtained with respect to the subspace spanned by the refined Ritz vectors. We discuss how to compute these new approximations cheaply and reliably. Theoretical error bounds between the original Ritz values and the new Ritz values are established. Finally, we present a variant of the refined Arnoldi al-gorithm for an augmented Krylov subspace and discuss restarting issue. Numerical results confirm efficiency of the new algorithm.

    Objective: The aim of the study was to investigate the effects of short-term overt hypothyroidism on lipids after thyroxine-withdrawal in patients with iatrogenically induced hypothyroidism before radioiodine treatment for differentiated thyroid carcinoma (DTC). Methods: Thirty patients with a history of differentiated thyroid carcinoma on thyroid-stimulating hormone (TSH)-suppressive thyroxine replacement therapy were studied. Blood sample were taken before and 4 weeks after withdrawal of thyroxine substitution. Venous blood was drawn after an overnight fast and analyzed for serum free T4 (FT4), free T3 (FT3), thyroid-stimulating hormone (TSH), total cholesterol (TC), triglyceddes (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and apolipoprotein A1 (ApoA1), apolipoprotein B (ApoB). Fifty healthy people matched for age and gender were controls. Their blood samples were taken only once. Results: After thyroxine-withdrawal, the patients presented with increased serum TSH and low serum FT4 and FT3 levels compared with controls. Serum TG, TC, LDL, HDL, APOB and Lp(a) increased after thyroxine withdrawal, reaching statistical significant dif-ferences with previous evaluation. However, when compared to euthyroid controls, only TC, LDL and ApoB were increased when patients were hypothyroidism. No changes were observed in ApoA1 in patients dudng thyroxine withdrawal, or when comparing the values observed in patients to those of euthyroid controls. Conclusion: TG, TC, LDL, HDL, APO8 and Lp(a) were increased during short-term overt hypothyroidism.

    Nanofluids (NFs) are nanotechnology-based colloidal suspensions fabricated by suspending nanoparticles (NPs) in a base liquid. These fluids have shown potential to improve the heat transfer prop-erties of conventional heat transfer fluids. In this study we report in detail on fabrication, characterization and thermo-physical property evaluation of SiC NFs, prepared using SiC NPs with different crystal structures, for heat transfer applications. For this purpose, a series of SiC NFs containing SiC NPs with different crys-tal structure (α-SiC and β-SiC) were fabricated in a water (W)/ethylene glycol (EG) mixture (50/50 wt%ratio). Physicochemical properties of NPs/NFs were characterized by using various techniques, such as pow-der X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fouriertransform infrared spectroscopy (FTIR), dynamic light scattering (DLS) and Zeta potential analysis. Thermo-physical properties including thermal conductivity (TC) and viscosity for NFs containing SiC particles (α- and β- phase) weremeasured. The results show among all suspensions NFs fabricated with α-SiC particles have more favorable thermo-physical properties compared to the NFs fabricated with β-SiC.The observed dif-ference is attributed to combination of several factors, including crystal structure (β- vs. α-), sample purity, and residual chemicals exhibited on SiCNFs. A TC enhancement of ∼20% while 14% increased viscosity were obtained for NFs containing 9 wt%of particular type ofα-SiC NPs indicating promising capability of this kind of NFs for further heat transfer characteristics investigation.

  16. An algorithmic calibration approach to identify globally optimal parameters for constraining the DayCent model

    Rafique, Rashid; Kumar, Sandeep; Luo, Yiqi; Kiely, Gerard; Asrar, Ghassem R.


    he accurate calibration of complex biogeochemical models is essential for the robust estimation of soil greenhouse gases (GHG) as well as other environmental conditions and parameters that are used in research and policy decisions. DayCent is a popular biogeochemical model used both nationally and internationally for this purpose. Despite DayCent’s popularity, its complex parameter estimation is often based on experts’ knowledge which is somewhat subjective. In this study we used the inverse modelling parameter estimation software (PEST), to calibrate the DayCent model based on sensitivity and identifi- ability analysis. Using previously published N2 O and crop yield data as a basis of our calibration approach, we found that half of the 140 parameters used in this study were the primary drivers of calibration dif- ferences (i.e. the most sensitive) and the remaining parameters could not be identified given the data set and parameter ranges we used in this study. The post calibration results showed improvement over the pre-calibration parameter set based on, a decrease in residual differences 79% for N2O fluxes and 84% for crop yield, and an increase in coefficient of determination 63% for N2O fluxes and 72% for corn yield. The results of our study suggest that future studies need to better characterize germination tem- perature, number of degree-days and temperature dependency of plant growth; these processes were highly sensitive and could not be adequately constrained by the data used in our study. Furthermore, the sensitivity and identifiability analysis was helpful in providing deeper insight for important processes and associated parameters that can lead to further improvement in calibration of DayCent model.

    Objective. To study the mechanism and effects of blood perfusion to the acute ischemic region of myecardium through Ho-YAG laser channels with myocardial contrast echocardiography Methods. To produce the model of acute myocardial ischemia, we partially ligated the left anterior decending (IAD)coromry artery of canine hearts between 1st. and 2nd. diagonal branches and then performed transmyocardial revasmgafizafion in this region with Ho- YAG laser. Myocardial contrast echecardingmphy was made with a new gen-eration of ultrasound contrast agent and second harmonic imaging of this region before,after ischemia and after laser revascalarizafion. Pictures were taken with “R” wave trigger skill. Results. Acoustic demity derterming in the ischemia region (anterior wall)with MCE(myocardial contrast e-checardiography) was obviously decreased(5.40 ± 1.81) after the LAD was ligated,as compared with before( 11.69± 1.61, P 0.05). There were no dif-ferences in acoustic density in the lateral wall(as control)among these comprehensive three periods (P > 0.05). Con-trast in the laser region developed one cardiac cycle ahead of that in the non-iscbemic normal region. Conclusion. Acute ischemic myecardium can be perfused by oxygenated blood from the left ventricle through Ho-YAG laser channels. Evidenee of blood perfusion through laser channels during systolic phase was detected,and my-ocardial cormast ultrasonngtaphy using intravenous perfluorocarbon-exposed sonicated dextrose albumin may be regard-ed as a reliable method in the study of tranmlyecardial revasculariztion.

  1. Effect of Spin Coupling with an External Magnetic Field on Thermospin in Quantum Dot%自旋与外磁场耦合对量子点中热自旋效应影响

    红亮; 海玉


    金属中热自旋赛贝克效应是纳米结构装置中的研究热点,它为解决器件运行中的热耗散和能源供给提供了一个可行的途径.本文考虑了量子点中自旋角动量和外磁场非共线时的耦合作用.研究结果显示外磁场和自旋角动量正交时可提高热自旋品质因子,与此同时在有限温差下,自旋流的强度将会被削弱.但当外磁场的方向调整到与自旋角动量反平行时,这种竞争关系会被消除,系统综合热自旋参数达到最佳.本文研究结果对量子点器件的设计具有重要的理论指导意义.%Metal thermospin Seebeck effect has been a focus of attention in the design of nanostructure device, since it makes the heat dissipation device operation and energy supply possible. In this study, we consider the coupling of spin an-gular momentum and the non-collinear external magnetic field in a quantum dot. The results show that the spin precession can improve the thermal spin quality factor, while spin current strength is reduced in the context of limited temperature dif-ference. However, such a competition can be eliminated and the overall system parameters of thermospin become optimal if the direction of the external magnetic field is adjusted to be opposite with that of spin angular momentum. Our results are important to the design of quantum dot devices.

  2. Atmospheric Corrections Using MODTRAN for TOA and Surface BRDF Characteristics from High Resolution Spectroradiometric/Angular Measurements from a Helicopter Platform


    High-resolution spectral radiance measurements were taken by a spectral radiometer on board a heli copter over the US Oklahoma Southern Great Plain near the Atmospheric Radiation Measurements (ARM) site during August 1998. The radiometer has a spectral range from 350 nm to 2500 nm at 1 nm resolution. The measurements covered several grass and cropland scene types at multiple solar zenith angles. Detailed atmospheric corrections using the Moderate Resolution Transmittance (MODTRAN) radiation model and in-situ sounding and aerosol measurements have been applied to the helicopter measurements in order to re trieve the surface and top of atmosphere (TOA) Bidirectional Reflectance Distribution Function (BRDF) characteristics. The atmospheric corrections are most significant in the visible wavelengths and in the strong water vapor absorption wavelengths in the near infrared region. Adjusting the BRDF to TOA requires a larger correction in the visible channels since Rayleigh scattering contributes significantly to the TOA reflectance. The opposite corrections to the visible and near infrarred wavelengths can alter the radiance dif ference and ratio that many remote sensing techniques are based on, such as the normalized difference vege tation index (NDVI). The data show that surface BRDFs and spectral albedos are highly sensitive to the veg etation type and solar zenith angle while BRDF at TOA depends more on atmospheric conditions and the vi ewing geometry. Comparison with the Clouds and the Earth's Radiant Energy System (CERES) derived clear sky Angular Distribution Model (ADM) for crop and grass scene type shows a standard deviation of 0.08 in broadband anisotropic function at 25° solar zenith angle and 0.15 at 50° solar zenith angle, respectively.

    Full Text Available The testis and epididymis of twenty five adult Large White boars were used to investigate the biometric and histomorphometric parameters of the testis and epididymis of the boars. The aim of the study was to provide information which could be useful in the comparative regional anatomy of the male reproductive organs of domestic animals and thus an improved assessment of breeding soundness and fertility potential in boars. The average weight of the animals was 71.3 ± 10.7 kg. The average weights of the right and left testes were 170 ± 0.7.60 g and 179±6.48g, respectively with no significant dif¬ference. The average weights of the right and left epididymis were 40.9 ± 6.81 g and 43.7 ± 8.55 g, respectively, with no significant difference. The relative testicular and epididymal weights were 0.49% and 0.12%, respectively. This study shows that the testis is about four times the size of the epididymis. The ductal diameter of the head, body and tail of the epididymis were 418 ± 22.6 µm, 432 ± 20.3 µm and 939 ± 50.6 µm, respectively. The mean relative volume of the germinal epithelium, interstitium and lumen of the seminiferous tubules of the boars rats were 68.4 ± 3.46%, 5.5 ± 0.66% and 78.0 ± 4.81%, respectively. It can be concluded that the morphology of the testis and epididymis of the Large White boar are similar to those of most mammals. This work provides information the testis and epididymis of the Large White boar which could be useful in the comparative regional anatomy of the male reproductive organs of domestic animals and thus an improved assessment of breeding soundness and fertility potential in boars.

  4. "Universalism"and"Relativism"of Anthropology%人类学的“普同”与“相对”



    现代人类学的开端,可追溯到19世纪,但人类学作为现代科学真正被确立起来,则要到20世纪20年代。长期以来,学科内部由于理念不同逐渐分野,形成两大主要分支,即以英、法两国为首的社会人类学,和以德、美两国为主的文化人类学。两派虽在学术理论、方向、思考方式等方面有所分歧,但并不妨碍他们各自为人类学学科所做出的巨大贡献。本文旨在介绍两派的主要学术观点,以及在人类学四大领域研究当中的理论实践。%The beginning of modern anthropology may date back to the 19th century, but setting as a real modern science subject would last to 1920. For a long time, due to the different disciplinary care, anthropology gradually formed two main branches, namely Britain, France, led by social anthropology, and in Germany, and the United States dominated cultural anthropology. Although there are some dif-ferences between the two factions, but it doesn't prevent a great contribution in their respective disciplines as anthropology made. This ar-ticle aims to introduce the two factions of the main academic point of view, as well as theory and practice in the field of anthropological re-search among the four.

  5. Using Pulse Rate in Estimating Workload Evaluating a Load Mobilizing Activity

    Juan Alberto Castillo


    Full Text Available Introduction: The pulse rate is a direct indicator of the state of the cardiovascular system, in ad-dition to being an indirect indicator of the energy expended in performing a task. The pulse of a person is the number of pulses recorded in a peripheral artery per unit time; the pulse appears as a pressure wave moving along the blood vessels, which are flexible, “in large arterial branches, speed of 7-10 m/s in the small arteries, 15 to 35 m/s”. Materials and methods: The aim of this study was to assess heart rate, using the technique of recording the frequency of the pulse, oxy-gen consumption and observation of work activity in the estimation of the workload in a load handling task for three situations: lift/transfer/deposit; before, during and after the task the pulse rate is recorded for 24 young volunteers (10 women and 14 men under laboratory conditions. We performed a gesture analysis of work activity and lifting and handling strategies. Results: We observed an increase between initial and final fp in both groups and for the two tasks, a dif¬ference is also recorded in the increase in heart rate of 17.5 for charging 75 % of the participants experienced an increase in fp above 100 lat./min. Par 25 kg, registered values indicate greater than 114 lat./min and 17.5 kg than 128 lat./min values. Discussion: The pulse rate method is recommended for its simplicity of use for operational staff, supervisors and managers and indus¬trial engineers not trained in the physiology method can also be used by industrial hygienists.

    The present paper mainly explicates Hempe’s critiques on the principle of “affirmation”and “falsification”toward the standard of the cognitive significance of the proposition.Based on the lo-gistic postulates,Hempe pointed out that the"affirmation"principle violates A theorem and its two in-ferences:A1 and A2.Seemingly,the "falsification" principle disobeys the above theorems too.In Hempe’s view,it is too narrow to the “affirmation”principle and too wide to the “falsification”princi-ple.In the end,Hempe made out an opinion of the “holistic explanation system”,and he gave four re-quirements on the system.In conclusion,Hempe’s idea is a theoretical origin and inspiration to the fol-lowing critiques on the Logical Empiricism,especially Quine’s “Two Dogmas of the Empiricism”.%亨普尔基于逻辑公理,指出“确证原则”违反了公理 A 和两个推论 A1和 A2。类似地,“证伪原则”也违反了上述公理。亨普尔认为“确证原则”过于狭窄,而“证伪原则”又太过于宽泛。他提出了一种整体的解释理论系统的观点,同时对意义解释系统的特点提出了四点要求。亨普尔的观点为蒯因彻底批判逻辑经验主义提供了重要的理论来源和启示。

  17. An Algorithm to Detect Tropical Deep Convective Clouds Through AMSU-B Water Vapor Channels

    XU Xu; Georg Heygster; ZHANG Suping


    An algorithm to detect tropical deep convective clouds and deep convective overshootings based on the measurements from the three water vapor channels (183.3GHz±1 GHz, 183.3GHz±3GHz and 183.3GHz±7GHz) of the Advanced Microwave Sounding Unit-B (AMSU-B) is presented. This algorithm is an improved version of the method of Hong et al. (2005). The proposed procedure is based on the statistical analysis of seven years'(2001-2007) measurements from AMSU-B on NOAA-16 From the 1-d histograms of the brightness temperature of the three water vapor channels and the 2-d tustograms of the brightness temperature dif-ference between these channels, new thresholds for brightness temperature differences and the brightness temperature of channel 18 (183.3 GHz±1 GHz) are suggested. The new algorithm is employed to investigate the mean distribution of tropical deep convective clouds and convective overshootings from 30°S to 30°N for the years 2001 to 2007. The major concentration of deep convective clouds and convective overshootings is found over the Intertropical Convergence Zone (ITCZ), the South Pacific Convergence Zone (SPCZ), tropical Africa, South America, the Indian Ocean and Indonesia with an average fraction of 0.4%. In terms of these clouds we identify the secondary Intertropical Convergence Zone located in the eastern South Pacific and parallel to the main ITCZ in the North Pacific. The convective overshooting is more frequently observed over land than over the ocean.

  19. Functional analysis of human Na~+/K~+-ATPase familial or sporadic hemiplegic migraine mutations expressed in Xenopus oocytes

    Susan; Spiller; Thomas; Friedrich


    AIM: Functional characterization of ATP1A2 mutations that are related to familial or sporadic hemiplegic migraine(FHM2, SHM). METHODS: cRNA of human Na+/K+-ATPase α2- and β1-subunits were injected in Xenopus laevis oocytes. FHM2 or SHM mutations of residues located in putative α/β interaction sites or in the α2-subunit’s C-terminal region were investigated. Mutants were analyzed by the twoelectrode voltage-clamp(TEVC) technique on Xenopus oocytes. Stationary K+-induced Na+/K+ pump currents were measured, and the voltage dependence of apparent K+ affinity was investigated. Transient currents were recorded as ouabain-sensitive currents in Na+ buffers to analyze kinetics and voltage-dependent presteady state charge translocations. The expression of constructs was verified by preparation of plasma membrane and total membrane fractions of cRNA-injected oocytes. RESULTS: Compared to the wild-type enzyme, the mutants G900R and E902K showed no significant dif-ferences in the voltage dependence of K+-induced currents, and analysis of the transient currents indicated that the extracellular Na+ affinity was not affected. Mutant G855R showed no pump activity detectable by TEVC. Also for L994del and Y1009X, pump currents could not be recorded. Analysis of the plasma and total membrane fractions showed that the expressed proteins were not or only minimally targeted to the plasma membrane. Whereas the mutation K1003E had no impact on K+ interaction, D999H affected the voltage dependence of K+-induced currents. Furthermore, kinetics of the transient currents was altered compared to the wild-type enzyme, and the apparent affinity for extracellular Na+ was reduced. CONCLUSION: The investigated FHM2/SHM mutations influence protein function differently depending on the structural impact of the mutated residue.

    To investigate the significance of waist circum-ference (WC), body mass index (BMI) and hyperinsuli-naemia A (Hlns) in evaluating metabolic syndrome (MS). Clinical data from middle-aged and senile indivi-duals (middle-senile group) who received glucose tol-erance test after diabetes mellitus screening and a group of subjects who received annual oral glucose tolerance test (OGTT) for diabetes mellitus screening (adult group) were collected. Data were collected by use of special mes-sengers, input into a computer data base and analyzed using SAS 5.0 software by expert staff. Abnormal WC and BMI were determined according to International Diabetes Federation (IDF) and Chinese Diabetes Society (CDS) criteria. Hlns was ascertained if fasting insulin (Fins)≥15 mU/L, and/or 2-hour insulin after a glucose challenge was (2hPIns)≥80 mU/L. Abnorma-lities in WC, BMI and Hlns were all found to be risk factors for abnormal glucose metabolism, hypertension and dyslipidemia. In the middle-senile group, the abnor-mality rate of WC and Hlns as well as the overall insulin level were significantly higher than those in the adult group. The abnormality rate of BMI was higher in the adult group, and HIns was mostly seen in impaired glu-cose test (IGT) and normal glucose test (NGT). The con-cordance rate of WC and BMI diagnostic criteria for evaluating obesity in the middle-senile and adult groups were 77.5% and 74.3%, respectively. When only the WC criterion was used for evaluating the existence of insulin resistance, there was a 28.2% missed diagnosis rate for MS patients. WC, BMI and Hlns were all risk factors for abnormal glucose metabolism, hypertension and dyslipi-demia. There was differing prevalence in the different populations. The combination of WC, BMI and Hlnsmight be more helpful in identifying MS at early stage.

    The jumbo flying squid (Dosidicus gigas) population was surveyed with the help of Chinese squid jigging vessels off the Costa Rica Dome (4˚-11˚N, 90˚-100˚W) in 2009 and 2010. The daily catch of D. gigas in the two survey cruises ranged from 0 to 5.5 t and was mostly obtained from the areas bounded by 6˚-9˚N and 91˚-94˚W and by 6˚30´-7˚30´N and 96˚-97˚W. The sea surface temperature in the areas yielding the most catch ranged from 27.5 to 29℃. The sex ratio of the total catch was 3.75:1 (female:male). The mantle length of the squid ranged from 211 to 355 mm (male) and from 204 to 429 mm (female) with an average of 297.9 and 306.7 mm, respectively. In the relationship of the mantle length (mm) and body weight (g) of the squid, there was no significant dif-ference between sexes. The female and male were at a similar maturity, and most individuals are maturing or have matured with a few females being spent. The size (mantle length) and age at the first sexual maturity were 297 mm and 195 d in females, and less than 211 mm and 130 d in males, respectively. Most of the sampled stomachs (70.6%) had no food remains. The major preys of the squids were fish, cephalopods and crustaceans, with the most abundant Myctophum orientale and D. gigas. The preys in more than 65%of the non-empty sampled stomachs evidenced the cannibalism of D. gigas. The results improved current understanding of the fishery biology of D. gigas off the Costa Rica Dome, which may facilitate the assessment and management of relative fishery re-sources.

    Full Text Available Introduction. Despite the advances in antibiotherapy and critical care management, infectious complications remain among the leading complications after liver transplantation related with mortality and morbidity. This study analysis the incidence and pattern of infections and possible prognostic factors of infectious compli- cations retrospectively in a single center. Patients and Methods. Results of 30 consecutive patients with a primary liver transplantation history in a single center between August 2011 and August 2012 and a positive culture result in the first month in the ICU were analysed retrospectively. Results. During the first 1 month stay in the ICU postoperatively 30 (13,63% patients had at least 1 infection. Total number of infections were 68. Mortality rate of the infected patients was 53,3% (n = 16. Among these infections, 25 (36,76% of them were in deep surgical sites. Eighteen of the 30 patients (60% were infected with a single microorganism. Eleven patients (36,66% had a single infection episode. Microorganism were gram negative in 52 (76,47% of the infections, gram positive in 14 (20,58% of the infections, rest of the 2 (2,94% infections were due to Candidiasis. Among the possible risk factors contributing to mortality, there was a statistically significant dif- ference (p < 0,001 between the platelet counts of the mortality and surviving groups of the patients. Conclu- sion. Infections are among the preventable risk factors for mortality and morbidity after liver transplantation. Our data reveals a significant relation between trombocytopenia and mortality among the infected patients. Further studies focusing on this relation would expose the mechanisms and any possible contribution in cli- nical management of the patients.

    Objective: To explore the effects of cytomegalovirus (CMV) infection on rejection-related gene expression in the endothelial cells of renal transplantation recipients. Methods: Endothelial cells (ECs) were cultured and stimulated by a variety of factors: A, normal control group; B, inactivated human cytomegalovirus (HCMV) infection group; C, HCMV infection group; D, HCMV supematant infection group; and E, ganciclovir HCMV group. Expression of intercellular adhesion molecule-1 (ICAM-1) and major histocompability complex (MHC) class Ⅰ and class Ⅱ antigens was detected by flow cytometry (FCM) and immuno-histochemistry. Results: We found characteristic CMV-infected ECs in this study. There were no significant differences among groups A, B and D (P>0.05). Although the expression levels of ICAM-1 were not significantly different between groups C and E (P>0.05), the ICAM-1 expression in these two groups was significantly higher than that in group A (P0.05). Human leucocyte antigen (HLA)-ABC expression was detected in all the groups, while HLA-DR expression was only detected in groups C and E. There were no significant dif-ferences of HLA-ABC and HLA-DR expression among groups A, B and D (P>0.05). However, the HLA-ABC and HLA-DR expression levels in groups C and D were higher than those of the remaining groups previously reported (P<0.05). Meanwhile, the HLA-ABC and HLA-DR expression levels in group E were lower than those of group C (P<0.05). Conclusion: CMV could up-regulate the expression levels of ICAM-1 and MHC antigens, which was closely related to allograft rejection.

    小儿先天性心脏病通常可分为发绀型与非发绀型.由于不同程度的左向右或右向左分流造成的血流动力学的改变.使呼气末与动脉血二氧化碳分压差[P(a-et)CO2]增大,给临床上通过呼气末二氧化碳分压(PETCO2)推测动脉血二氧化碳分压(PaCO2)带来困难.因此,如何正确地评估和预测PaCO2,避免过多地进行动脉血气分析是十分必要的.此文参考近年来的研究,对可能影响P(a-et)CO2值的各种因素作一综述.%The pediatric congenital heart diseases are usually divided into cyanotic and non-cyanotic heart diseases. Due to the hemodynamic change caused by either left-right or right-left shunt, the value of arterial-to-end-tidal carbon dioxiede tension dif-ference (P(a- et)CO2) increases, which makes it difficult using pressure of end-tidal carbon dioxide (PETCO2) to predict pressure of arterial carbon dioxide (PaCO2). Therefore, in order to avoid excessive artery blood gas analysis, it is important to estimate and pre-dict PaCO2 exactly, especially in pediatric patients. The present review gathers various factors that probably influence P(a-et)CO2 and try to make a simple conclusion, based on published data recently.

  7. Live facial feature extraction

    ZHAO JieYu


    Precise facial feature extraction is essential to the high-level face recognition and expression analysis. This paper presents a novel method for the real-time geomet-ric facial feature extraction from live video. In this paper, the input image is viewed as a weighted graph. The segmentation of the pixels corresponding to the edges of facial components of the mouth, eyes, brows, and nose is implemented by means of random walks on the weighted graph. The graph has an 8-connected lattice structure and the weight value associated with each edge reflects the likelihood that a random walker will cross that edge. The random walks simulate an anisot-ropic diffusion process that filters out the noise while preserving the facial expres-sion pixels. The seeds for the segmentation are obtained from a color and motion detector. The segmented facial pixels are represented with linked lists in the origi-nal geometric form and grouped into different parts corresponding to facial com-ponents. For the convenience of implementing high-level vision, the geometric description of facial component pixels is further decomposed into shape and reg-istration information. Shape is defined as the geometric information that is invari-ant under the registration transformation, such as translation, rotation, and iso-tropic scale. Statistical shape analysis is carried out to capture global facial fea-tures where the Procrustes shape distance measure is adopted. A Bayesian ap-proach is used to incorporate high-level prior knowledge of face structure. Ex-perimental results show that the proposed method is capable of real-time extraction of precise geometric facial features from live video. The feature extraction is robust against the illumination changes, scale variation, head rotations, and hand inter-ference.

    XU Xiao-niu; Hideaki SHIBATA


    Within a forested watershed at the Uryu Experimental Forest of Hokkaido University in northern Hokkaido, overstory litterfall and related nutrient fluxes were measured at different landscape zones over two years. The wetland zone covered with Picea glehnii pure stand. The riparian zone was deciduous broad-leaved stand dominated by Alnus hirsuta and Salix spp., while the mixture of deciduous broadleaf and evergreen conifer dominated by Betula platyphylla, Quercus crispula and Abies sachalinensis distributed on the upland zone.Annual litterfall averaged 1444, 5122, and 4123 kg·hm-2·a-1 in the wetland, riparian and upland zones, respectively. Litterfall production peaked in September-ctober,and foliage litter contributed the greatest amount (73.4%-87.6 %) of the annual total litterfall. Concentrations of nutrients analyzed in foliage litter of the dominant species showed a similar seasonal variation over the year except for N in P. Glehnii and A. Hirsuta. The nutrient fluxes for all elements analyzed were greatest on riparian zone and lowest in wetland zone. Nutrient fluxes via lit terfall followed the decreasing sequence: N (11-129 kg·hm-2·a-1) > Ca (9-69) > K (5-20) > Mg (3-15) > P (0.4-4.7) for all stands. Significant differences were found in litterfall production and nutrient fluxes among the different landscape components. There existed significantdif ferences in soil chemistry between the different landscape zones. The consistently low soil C:N ratios at the riparian zone might be due to the higher-quality litter inputs (largely N-fixing alder).

  9. Designing Experiments that Contr ol for Spatial and Temporal Variation

    Peter Petraitis


    Full Text Available Spatial and temporal variation can cause problems in designing and conducting experiments. An introduction to methods for controlling spatial and temporal variation in ecological experiments is provided in this article. Failure to consider spatial and temporal variation often causes researchers to lay out experiments incorrectly . The challenge is to design experiments that not only reflect the natural variation seen in the field but also control for the variation so that statistical tests have suf ficient power . Spatial variation is usually controlled by grouping observations and treatments into blocks. Blocks can be laid out in a number of ways and Analysis of Variance (ANOV A approaches to control for block effects are discussed. The control of temporal variation presents special dif ficulties because data are often serially correlated and so observations are not independent. Use of intervention analysis and repeated measures analysis of variance to control for temporal variation are discussed. Ecologists have also used experimental designs which are known as BACI designs (i.e., Before-After -Control-Impact design and can be extended to include multiple control and/or impact sites. Intervention analysis, BACI designs, and their extensions have subtle dif ferences because of dif ferent assumptions about not only temporal variation but also spatial variation. Several recommendations are given. These include: 1 the need to have good statistical advice before starting an experiment, 2 the need to have a suf ficient number of replicates that are spread over the range of spatial and temporal variation, and 3 the need to correctly control for serial correlation.

  12. Causes Analysis and Empirical Test of Continued Accumulation of Foreign Exchange Reserves%外汇储备持续积累的原因分析及实证检验

    李妍; 周鑫


    Based on the data from 1990 to 2009, this paper analyzes the reasons why China's foreign exchange re- serves continue to accumulate from the perspectives of supply and demand for foreign exchange. From the perspective of foreign exchange supply, GDP, total exports, the actual use of foreign direct investment and foreign debt from foreign exchange reserves are supply factors as explanatory variables, in which gross domestic product; exports of foreign exchange reserves play a more significant role. From the perspective of foreign exchange demand, exchange rate, the difference between domestic interest rates and foreign interest rates are demand factors as explanatory vari- ables, in which the exchange rate has a positive impact on the foreign exchange reserve growth. However the dif- ferences between domestic interest rates and foreign interest rates have little effect on the reserves.%基于1990到2009年数据,本文从外汇供给和外汇需求角度分析我国外汇储备持续积累的原因。从外汇供给角度看,国内生产总值、出口总额、实际使用外商直接投资、外债余额作为源于外汇储备供给因素的解释变量,其中国内生产总值、出口总额对外汇储备具有较明显作用。从外汇储备需求角度看,汇率、国内外利率比作为源于外汇储备需求因素的解释变量,其中汇率对外汇储备增长有正向影响,国内外利率比对外汇储备增长影响甚微。

    Using the automatic weather station data obtained from the Tibetan Plateau (TP), the normalized dif-ference vegetation index and the monthly precipitation data of China and by the methods of correlation and composite analysis, preliminary analytical results are achieved concerning the relationships be-tween TP NDVI change and its surface heat source and precipitation of China. The results of our re-search may lead to the following conclusions: (1) A positive correlation relationship exists between TP NDVI change and its surface heat source, including the sensible heat and the latent heat. As to the correlation of the former, it is more remarkable in western TP than in eastern TP, and as to the correla-tion of the latter, however it turns out contrary. (2) With the improvement of TP vegetation, its surface heat source of every season is also mainly reinforced, especially in summer. As to the contribution of the sensible heat and the latent heat to the increment of the TP surface heat source intensity, the for-mer is comparatively more significant than the latter in winter and spring, while in summer and autumn, the two have almost the same importance. (3) The correlation coefficient between summer NDVI over TP and the corresponding period precipitation of China displays a belt distribution of "+-+" from south to north China. (4) Anomalous surface heating field over TP derived from vegetation change is probably an important factor to affect summer precipitation of China.keywords Tibetan Plateau, vegetation change, surface heat source, precipitation of China.

  17. Effect of Clenbuterol Hydrochloride on the in vitro Development of Mouse Embryo


    Objective To investigate the effect of clenbuterol hydrochloride on the in vitro devel-opment of both 1-cell and 2-cell mouse embryos.Methods The cultural systems of both 1-cell and 2-cell mouse embryo were used todetermine the effect of clenbuterol hydrochloride at doses of 1 ng/mL, 3 ng/mL, and10 ng/mL on developmental rates of mouse embryos.Results When 1-cell embryos cultured with 1 ng/mL of clenbuterol hydrochloride,developmental rates from the 4-cell stage to blastocyst stage were significantly lowerthan those in the control group (P< 0. 05), but on dosages of 3 ng/mL and 10ng/mL,the inhibiting effects on embryo development were significantly increased (P< 0. 01).When 2-cell embryos cultured with 1 ng/mL of clenbuterol hydrochloride, obvious dif-ferences in developmental rates were not found between the 2-cell embryo group and thecontrol (P> 0. 05). However, at levels of 3 ng/mL and 10 ng/mL, significant de-crease of developmental rates in 2-cell embryos was observed from the 4-cell and fromthe 8-cell stage, respectively (P< 0. 05). Embryos cultured with clenbuterol hydrochlo-ride appeared to have more granules, fragments and degeneration than those in thecontrol.Conclusion Clenbuterol hydrochloride has a toxic effect on the mouse embryos, and theeffect is in a dose-dependent. 1-cell mouse embryos cultured with clenbuterolhydrochloride could be easily inhibited at 2-cell stage, but the effect of clenbuterolhydrochloride on development of the late 2-cell embryos would be reduced.

  18. Ecological Ethical Implications of Xunzi’s Concept of Heaven and Man%荀子天人观的生态伦理意蕴



    荀子作为先秦时期儒家思想的集大成者,解百家之蔽,取诸子之长,其天人观所蕴含之深切的生态伦理关怀,映照今日生态文明建设之显题,启示我们在处理天人关系时,应明于天人之分,依循天道而行;在生态文明建设过程中,当制天命而用之,凸显人之主体;而达于天人合一,促进生态和谐当成为人与自然共处之要义。%Xunzi, as the Pre-Qin Dynasty Confucianism synthesizer, overcomes defects of schools of various thoughts, and absorbs their advantages. The deep ecological ethical concern of his concept of heaven and man, cor-responding to the theme of ecological civilization construction today, reveals to us that we should distinguish the dif-ference between heaven and man when dealing with their relationship and abide by the law of heaven. In ecologi-cal civilization construction process, we should take advantage of the laws of nature to highlight the dominant posi-tion of the human beings, to reach the union of heaven and man and to promote ecological harmony, which should be the essence of the principles of coexistence between man and nature.

    AIM:To compare the influence of different transplant sites in bone marrow mesenchymal stem cell (MSC)-based therapy for liver fibrosis.METHODS:MSCs isolated from Sprague Dawley (SD) rats were induced into hepatocyte-like cells.Liver fibrosis in SD rats was induced with carbon tetrachloride.Following hepatocyte induction in vitro,4',6-diamidino2-phenylindole (DAPI)-labeled MSCs were transplanted by intravenous,intrahepatic,and intraperitoneal injection.Histopathological staining,immunohistochemistry,and biochemical analysis were used to compare the morphological and functional liver regeneration among different MSC injection modalities.The expression di-ferences of interleukins,growth factor,extracellular matrix,matrix metalloproteinases,and tissue inhibitor of metalloproteinase were examined by real-time reverse transcription-polymerase chain reaction (RT-PCR) and enzyme linked immunosorbent assay (ELISA).RESULTS:Four days after exposure to hepatocyte differentiation medium,MSCs that did not express hepatocyte markers could express α-fetoprotein,albumin,and cytokeratin 18.The results of histopathological staining,immunohistochemistry,and biochemical analysis indicated that intravenous injection is more effective at rescuing liver failure than other injection modalities.DAPI-labeled cells were found around liver lobules in all three injection site groups,but the intravenous group had the highest number of cells.PCR and ELISA analysis indicated that interleukin-10 (IL-10)was highest in the intravenous group,whereas il1β,il6,tnfα and tgfβ,which can be regulated by IL10 and are promoters of liver fibrosis,were significantly lower than in the other groups.CONCLUSION:MSC administration is able to protect against liver fibrosis.Intravenous injection is the most favorable treatment modality through promotion of IL10 expression.

  1. Playing the Part: Hungarian Boy Scouts and the Performance of Trauma in Interwar Hungary

    Steven Jobbitt


    Full Text Available In 1920, the historic Kingdom of Hungary was dismembered according to the dictates of the Treaty of Trianon. Resulting in the loss of two-thirds of the nation’s pre-World War I territory, and one-third of its prewar population, Trianon has long stood as a symbol for Hungarian suffering and trauma in the twentieth century. Historians of modern Hungary have given much consideration to Trianon, with serious attention being paid to what some have called the Trianon syndrome, or the Trianon trauma. Arguing that interwar Hungarian culture and politics need to be understood in light of the menacing psychological shadow cast by Trianon, a number of historians have suggested that the people of Hungary were traumatized spontaneously and universally by the dismemberment of the nation and the suffering that followed. This paper argues that, though this may indeed have been the case on a raw emotional level, careful consideration needs to be given to the overlapping political and pedagogical functions of the Trianon trauma, especially as this trauma found expression in repeated public “performances” of the Trianon tragedy. Focusing on the revisionist performances of Hungarian boy scouts between the wars, and in particular on the personal papers of the Hungarian geographer and boy scout leader Ferenc Fodor, this paper draws a direct link between trauma and performance in the interwar period, and argues that, though trauma was indeed central to Hungarian cultural politics, it functioned as much as a pedagogical strategy as it did a psychological reality.

    Antje Jansen; Sabine Harenberg; Uwe Grenda; Christoph Elsing


    AIM: To evaluate the r isk factor s -other than nonsteroidal anti-inflammatory drugs-for colonic diverticular bleeding in a westernized population.METHODS: One hundred and forty patients, treated for symptomatic diverticular disease in a community based hospital, were included. Thirty (21%) had signs of diverticular bleeding. Age, gender, and the results of colonoscopy were collected and compared to a group of patients with nonbleeding symptomatic diverticulosis. Records were reviewed for comorbidities,such as obesity, alcohol consumption, smoking habits and metabolic diseases. Special emphasis was put on arterial hypertension, cardiovascular events, diabetes mellitus, hyperuricemia and hypercholesterinemia.RESULTS: There was no di f ference between patients with diverticular hemorrhage and those with nonbleeding symptomatic diverticulosis regarding gender ratio (male/female 9/21 vs 47/63) and diverticular localisation. Bleeding patients differed in respect to age (73.4±vs67.8±13.0,p<0.013).Significant differences were found between both groups regarding the presence of hyperuricemia and use of steroids and nonsteroidal anti-inflammatory drugs. Patients with three concomitant metabolic diseases were also identified as being at risk of bleeding. A forward stepwise logistic regression analysis revealed steroids, hyperuricemia and the use of calcium-channel blockers as independent risk factors of bleeding.CONCLUSION: Beside nonsteroidal anti-inflammatory steroid drug use, antihypertensive medication and concomitant arteriosclerotic diseases are risk factors for colonic diverticular hemorrhage. Our results support the hypothesis of an altered arteriosclerotic vessel as the source of bleeding.

    Based on sucrose solution as the research object, this paper measured the trans-reflective spectrum of sucrose solution of different concentration by the technique of near infrared spectrum in three optical path (4, 5, 6 mm). Five kinds of pretreatment method (vector normalization, baseline offset correction, multiplicative scatter correction, standard normal variate transformation, a derivative) were used to eliminate the influence of the optical path difference, and to establish model of the calibration set in combination with the PLS (Partial Least Squares)method. Five kinds of pretreatment method could restrain the inter ference of light path in varying degrees. Compared with the PLS model of original spectra, the model of multiple scattering correction combined with PLS method is the optimal model. The results of quantitative analysis of original spectra: the number of principal component PC= 6, the determination coefficient R2 = 0.891 278, the determination coefficient of cross validation R2CV = 0.888 374, root mean square error of calibration RMSEC = 1.704%, root mean square error of cross validation RMSECV = 1.827%; The results of quantitative analysis of spectra after MSC pretreatment: the number of principal component PC = 3, the determination coefficient R2 = 0.987 535, the determination coefficient of cross validation R2CV = 0.983 343, root mean square er- ror of calibration RMSEC = 0.89%, root mean square error of cross validation RMSECV = 1.05%. The correlation coefficient of the prediction set is as much as 0.976 22. root mean square error of prediction is 0.01, lesser than 0.014 36.

  6. Austro-Hungarian Bank building in Subotica

    Aladžić Viktorija


    Full Text Available During the negotiations between Austria and Hungary in 1867 when dual Austro-Hungarian Monarchy was formed, the question of the central bank was not touched to prevent further complications. In 1878, after years of prolonged negotiations, the central bank was successfully transformed into an institute in which Austria and Hungary had an equal share. The 'Austro- Hungarian Bank' acted as a central bank for both parts of the Empire. The dualistic character of the institute was characterized by two managements and two head offices in Vienna and Budapest. During first decade of 20th century it was built few dozens of bank buildings in Hungary and the most important: the central Austro-Hungarian Bank building in Budapest on Szabadsbg tjr 8. Bank building in Budapest was built according to the design made by Ignbc Alpbr who won the competition. Most of the other bank buildings built throughout Hungary were designed by architect Juzsef Hubert, but Austro-Hungarian bank building in Subotica was designed by architect Ferenc Juzsef Raichl in 1901. Main topic of this paper is research of architecture of Austro-Hungarian Bank Building in Subotica. It is obvious, although smaller in size, that the building was designed according to the main concept of the central bank building in Budapest. Compositions of the both facade applied similar architectural elements, like pillars, projections, attics, plinth and also decorative elements that symbolizes the function of a building. Inner organization of space also corresponds to each other, in both buildings: beside offices there were several apartments for renting. In contrast to other bank buildings in Hungary designed by Juzsef Hubert, bank building in Subotica, although made according to the concept of Central Bank building in Budapest represents remarkable and unique architectural masterpiece including all: architectural composition, decorative elements and function of a building.

    词汇量是衡量英语水平的一个重要因素。本文通过对高三学生的调查,探讨不同水平的学生在词汇学习策略使用上的异同。结果表明,词汇量水平高的学生在整体策略使用频率上明显高于词汇量水平低的学生。另外,不同水平组的学生还表现出来一些共同特点,包括整体元认知策略水平低、缺乏合作学习意识、不善于利用网络等媒体资源等。本文分析了这些异同的原因并指出通过教学使学生掌握相应的词汇学习策略有助于他们水平的提高。%Vocabulary is one of the important factors to measure English level. This paper explores the similarities and dif- ferences of vocabulary learning strategy use by investigating 630 third-year senior high school students with different vocabulary. It finds out that students with wider vocabulary uses learning strategies more frequently than their counterparts with limited vo- cabulary. Meanwhile, students of different vocabulary levels show some commonalities in strategy use including low frequency in the use of metacognitive strategy, lack of cooperative sense in learning, and failure in utilizing media resources in learning vocab- ulary. The paper points out that teaching students to master correspondent strategies in learning vocabulary can help them im- prove their English level.

    Allahyar Geramy


    Full Text Available Objectives: This study sought to assess distal and lateral forces and moments of asymmetric headgears by variable outer bow lengths.Materials and Methods: Four 3D finite element method (FEM models of a cer- vical headgear attached to the maxillary first molars were designed in SolidWorks2010 software and transferred to ANSYS Workbench ver. 11 software. Modelscontained the first molars, their periodontal ligament (PDL, cancellous and cor- tical bones, a mesiodistal slice of the maxillae and the headgear. Models were the same except for the outer bow length in headgears. The headgear was symmetric in model 1. In models 2 to 4, the headgears were asymmetric in length with dif- ferences of 5mm, 10mm and 15mm, respectively. A 2.5 N force in horizontal plane was applied and the loading manner of each side of the outer bow was cal- culated trigonometrically using data from a volunteer.Results: The 15mm difference in outer bow length caused the greatest difference in lateral (=0.21 N and distal (= 1.008 N forces and also generated moments (5.044 As the difference in outer bow length became greater, asymmetric effects increased. Greater distal force in the longer arm side was associated with greater lateral force towards the shorter arm side and more net yawing moment. Clinical Relevance:A difference range of 1mm to 15 mm of length in cervical headgear can be consi-dered as a safe length of outer bow shortening in clinical use.

    Kang SUN; Shao-qi TIAN; Ji-hua ZHANG; Chang-suo XIA; Cai-long ZHANG; Teng-bo YU


    Objective: To analyze the clinical outcomes of arthroscopic anterior cruciate ligament (ACL) reconstruction with irradiated bone-patellar tendon-bone (BPTB) allograft compared with non-irradiated allograft and autograft. Methods: All BPTB allografts were obtained from a single tissue bank and the irradiated allografts were sterilized with 2.5 mrad of irradiation prior to distribution. A total of 68 patients undergoing arthroscopic ACL reconstruction were prospectively randomized consecutively into one of the two groups (autograft and irradiated allograft groups). The same surgical technique was used in all operations done by the same senior surgeon. Before surgery and at the average of 31 months of follow-up (ranging from 24 to 47 months), patients were evaluated by the same observer according to objective and subjective clinical evaluations. Results: Of these patients, 65 (autograft 33, irradiated allograft 32) were available for full evaluation. When the irradiated allograft group was compared to the autografi group at the 31-month follow-up by the Lachman test, the anterior drawer test (ADT), the pivot shift test, and KT-2000 arthrometer test, statistically significant differences were found. Most importantly, 87.8% of patients in the autograft group and just only 31.3% in the irradiated allograft group had a side-to-side difference of less than 3 mm according to KT-2000. The failure rate of the ACL reconstruction with irradiated allograft (34.4%) was higher than that with autograft (6.1%). The anterior and rotational stabilities decreased significantly in the irradiated allograft group. According to the overall International Knee Docu-mentation Committee (IKDC), functional and subjective evaluations, and activity level testing, no statistically significant dif-ferences were found between the two groups. Besides, patients in the irradiated allograft group had a shorter operation time and a longer duration of postoperative fever. When the patients had a fever

    Full Text Available Objectives: To determine the best anthropometric index in rela-tion to cardiovascular disease risk factors among children and adolescents. Methods: This cross-sectional school-based study was conducted among a random sample of 3179 students, aged 6 to 18 years, in three large cities in Brazil. Results: The prevalence of overweight and obesity was 10% and 5%, respectively. In relation to the students in the lower quartile (Q1 of the distribution of subscapular skinfold, the students in the upper quartile (Q4 presented a 2.0 times higher risk (odds ratio of having elevated total cholesterol levels. Overweight and obese students had a 3.3 times higher risk of having elevated sys-tolic blood pressure, and a 1.9 times higher risk of elevated diastolic blood pressure than other students. The less active students presented a 1.58 times higher risk of having waist-to-height ratio (WHtR above the upper tertile (Q3. WHtR mean values was 0.46 (SE 0.00 presented the largest area under the curve (AUC [0.613 (CI995%:0.578-0.647] for high total cholesterol levels, [0.546 (CI995%: 0.515-0.578] for low HDL-C levels, and [0.614 (CI95%: 0.577-0.651] for high LDL-C levels, while body mass index presented the largest AUC [0.669 (CI95%: 0.64-0.699] for increased diastolic blood pressure followed by the waist circum-ference for increased systolic blood pressure [0.761 (CI95%: 0.735-0.787]. Conclusions: WHtR is considered as a simple and accurate anthropometric parameter that identifies youth with cardiovascular risk factors. In this study, WHtR above 0.44 was indicative of risk factors in children and adolescents. These findings can be applied in future preventive strategies against CVDs, and screening pro-grams.

The specific aims were to compare the prevalence of autoimmune, psychiatric, endocrine, gynecologic pathology, the relationship between timing of gynecologic surgery, and pain onset. We additionally sought to compare the number of comorbidities in an ethnically diverse cohort.Methods: This was a retrospective chart review of patients seen in FM or CP clinics at an academic medical center in 2009–2010.Results: Logistic regression modeling found that gynecologic, endocrine, and autoimmune diagnoses were independently associated with a diagnosis of FM. Detailed analyses showed that thyroid disease (P<0.01 and gynecologic surgery (P<0.05 were significantly more common in FM. Women with FM were more likely to have multiple autoimmune, endocrine, gynecologic, or psychiatric pathologies. A relationship was observed between the timing of gynecologic surgery and pain onset in FM, with more surgeries observed in the years just prior to pain onset or in the year after pain onset. A similar pattern was not found in the control group.Conclusion: This study demonstrates that autoimmune, endocrine, and gynecologic pathologies occur more commonly in women with FM than in those with CP, which is consistent with findings in less ethnically diverse samples. Moreover, a relationship was found between timing of pain onset and gynecologic

    Fretheim Atle


    Full Text Available Abstract Background We conducted a systematic review of evidence from randomized controlled trials to answer the following research question: What are the relative effects of different classes of antihypertensive drugs in reducing the incidence of cardiovascular disease outcomes for healthy people at risk of cardiovascular disease? Methods We searched MEDLINE, EMBASE, AMED (up to February 2011 and CENTRAL (up to May 2009, and reference lists in recent systematic reviews. Titles and abstracts were assessed for relevance and those potentially fulfilling our inclusion criteria were then assessed in full text. Two reviewers made independent assessments at each step. We selected the following main outcomes: total mortality, myocardial infarction and stroke. We also report on angina, heart failure and incidence of diabetes. We conducted a multiple treatments meta-analysis using random-effects models. We assessed the quality of the evidence using the GRADE-instrument. Results We included 25 trials. Overall, the results were mixed, with few significant dif-ferences, and with no drug-class standing out as superior across multiple outcomes. The only significant finding for total mortality based on moderate to high quality evidence was that beta-blockers (atenolol were inferior to angiotensin receptor blockers (ARB (relative risk (RR 1.14; 95% credibility interval (CrI 1.02 to 1.28. Angiotensin converting enzyme (ACE-inhibitors came out inferior to calcium-channel blockers (CCB regarding stroke-risk (RR 1.19; 1.03 to 1.38, but superior regarding risk of heart failure (RR 0.82; 0.69 to 0.94, both based on moderate quality evidence. Diuretics reduced the risk of myocardial infarction compared to beta-blockers (RR 0.82; 0.68 to 0.98, and lowered the risk of heart failure compared to CCB (RR 0.73; 0.62 to 0.84, beta-blockers (RR 0.73; 0.54 to 0.96, and alpha-blockers (RR 0.51; 0.40 to 0.64.

The early detection for infections of Staphylococcus aureus in burned children is very important, also the pre-vention for consequences of TSST-1. Fever is one of the most noticeable sign in burned children. On the other hand, fever is one of the important consequences of TSST-1 pro-duction. Methods: This study aimed to assess the toxic shock syndrome toxin-1 level in the wound’s specimens of two groups febrile and afebrile in the hospitalized burned chil-dren in Motahari hospital Tehran, Iran in the year 2013. In this case-control study, 90 children who admitted to the burn unit, divided in two groups of 45 patients: febrile (cases group and afebrile (control group. All of burned children under went wound biopsy, and then all of wound’s specimens were tested by PCR for specific primer of toxin producing genome. Finally all of data collected and statistically analyzed. This data include group febrile and afebrile, demographic characteristics, percentage of burned surface severity and result of PCR. Results: The positive result for PCR test, production of TSST-1 in febrile burned chil-dren (cases group was 37.7% and in afebrile burned children (control group was 11.1% that this different was statistically significant (P=0.003. The mean and stan-dard deviation for percentage of burned surface (severity in samples with positive re-sult for PCR test was 30.9±16.93 and in samples with negative result for PCR test was 20.09±11.02 that this different was statistically significant (P=0.01. There was no dif-ference between positive PCR result and negative PCR result of age and sex. Conclusion: Direct association was approved between the production of TSST-1 and the occurrence of fever in burned children. Increased surface severity of burns also re-lated to the production of TSST-1. Further research is recommended.

However, diamond particles possess a strong propensity to aggregate in liquid formulation media, restricting their applicability in biomedical sciences. Here, the authors describe the covalent functionalization of NDs with lysine in an attempt to develop nanoparticles able to act as suitable nonviral vectors for transferring genetic materials across cellular membranes.Methods: NDs were oxidized and functionalized by binding lysine moieties attached to a three-carbon-length linker (1,3-diaminopropane to their surfaces through amide bonds. Raman and Fourier transform infrared spectroscopy, zeta potential measurement, dynamic light scattering, atomic force microscopic imaging, and thermogravimetric analysis were used to characterize the lysine-functionalized NDs. Finally, the ability of the functionalized diamonds to bind plasmid DNA and small interfering RNA was investigated by gel electrophoresis assay and through size and zeta potential measurements.Results: NDs were successfully functionalized with the lysine linker, producing surface loading of 1.7 mmol g-1 of ND

    K Rajkumar


    Full Text Available Background : The design of the tooth preparation and the cementing medium are important consid-erations in the retention of crowns and fixed partial dentures. The purpose of this invitro study was to determine the effect of axial groove on the retention of complete cast metal crowns using two resin luting cements. Methods: Forty freshly extracted intact human molar teeth were prepared in their long axis to receive complete cast metal crowns. The specimens were randomly divided into two groups (one control and one study group. An axial groove of uniform size and shape was made on the prepared teeth under the study group. Axial surface area of prepared teeth specimens was measured. Complete cast metal crowns were fabricated for each specimen. Specimens of each group were divided into subgroups of 10 samples and were cemented with two resin luting cements, RelyX Unicem® and Calibra®, re-spectively. The cemented crowns were loaded in tension using a Universal Instron testing machine. The maximal tensile strength was recorded. Data were compared using the Mann-Whitney U test (α=0.05. Results: No significant differences in the tensile stress values were noted between the control (mean: 5.76±0.392 MPa and study (mean: 5.93±0.751 MPa groups cemented with RelyX Unicem. No sig-nificant differences in the tensile stress values were noted between the control (mean: 4.92±0.641 MPa and study (mean: 5.15 ±0.478 MPa groups cemented with Calibra. However, significant dif-ference in the tensile stress values was found between the two resin cements in the control and study groups. Conclusion: Axial groove placed in tooth preparations for resin bonded complete cast metal crowns had no statistically significant effect on retention. The use of (RelyX Unicem® yielded greater reten-tion values when compared to Calibra®.

  17. [Male contraception].

    Demoulin, A


    Among the reasons why male hormonal contraception has lagged behind female methods are the necessity of preserving virility, the fact that spermatogenesis is a continuous process, the need to control secondary effects and toxicity, and the requirement that modes of administration be acceptable to both partners. Among currently available reversible mehtods, withdrawal is undoubtedly the most ancient. It is still widespread but cannot be recommended because of its limited effectiveness. The condom is used by about 10% of couples worldwide as a principal or temporary method, but its inter-ference with sensation has limited its acceptance. Condoms are nevertheless highly effective when used with a spermicide. Various androgens are currently under investigation. High doses of testosterone can induce azoospermia without affecting libido but their side effects may be serious. The use of combinations of steroids permits doses to be reduced and offers promise for the future. The combination of oral medroxyprogesterone acetate and percutaneous testosterone is one of the better approaches; the combination is effective and nontoxic but has the disadvantage of percutaneous administration. Gossypol, a pigment extracted from the cotton plant, has been used as a contraceptive in China with a reported efficacy of 99.89%, recovery of fertility within 3 months, and no effect on future fertility. However, its toxicity appears to be significant in the animal and its reversibility is uncertain. A search is on for analogs which would preserve the contraceptive effects while eliminating toxic effects. Several gonadotropin releasing hormone (GnRH) analogs under investigation for their interference with spermatogenesis have given promising results. Several chemicals tested for contraceptive effects have had unacceptably high toxicity. Chinese investigators have reported good results with various physical methods of interfering with sperm production, but their reversibility and innocuity

    AIM: We investigated the relationship between taste sensitivity, nutritional status and metabolic syndrome and possible implications on weight loss dietary program. METHODS: Sensitivity for bitter, sweet, salty and sour tastes was assessed by the three-Alternative-Forced-Choice method in 41 overweight(OW), 52 obese(OB) patients and 56 normal-weight matched controls. OW and OB were assessed also for body composition(by impedence), resting energy expenditure(by indirect calorimetry) and presence of metabolic syndrome(MetS) and were prescribed a weight loss diet. Compliance to the weight loss dietary program was defined as adherence to control visits and weight loss ≥ 5% in 3 mo. RESULTS: Sex and age-adjusted multiple regression models revealed a significant association between body mass index(BMI) and both sour taste(P < 0.05) and global taste acuity score(GTAS)(P < 0.05), with lower sensitivity with increasing BMI. This trend in sensitivity for sour taste was also confirmed by the model refitted on the OW/OB group while the association with GTAS was marginally significant(P = 0.06). MetS+ subjects presented higher thresholds for salty taste when compared to MetS- patients while no significant difference was detected for the other tastes and GTAS. As assessed by multiple regression model, the association between salty taste and MetS appeared to be independent of sex, age and BMI. Patients continuing the program(n = 37) did not show any difference in baseline taste sensitivity when compared to drop-outs(n = 29). Similarly, no significant difference was detected between patients reporting and not reporting a weight loss ≥ 5% of the initial body weight. No significant dif-ference in taste sensitivity was detected even after dividing patients on the basis of nutritional(OW and OB) or metabolic status(MetS+ and MetS-). CONCLUSION: There is no cause-effect relationship between overweight and metabolic derangements. Taste thresholds assessment is not useful in

    Azam Azargoon


    Methods: In this quasi-experimental research, we studied 70 women with ectopic preg-nancies who were treated with MTX, according to a single dose protocol from 2010 to 2013. EP was diagnosed whenever an intrauterine gestational sac was not identified by transvaginal ultrasonography (TVUS, accompanied by an abnormal rise or plateau in human chorionic gonadotropin (beta-hCG concentration. Briefly, women with ectopic pregnancies were considered candidates for MTX treatment if they were hemodynami-cally stable; did not desire surgical therapy, agreed to weekly follow-up; and did not have hepatic, hematologic, or renal disease. A Patient was considered a treatment suc-cess (group 1 if her beta-hCG levels decreased ≤10 m IU/ml after the first dose of MTX. Treatment failure (group 2 was defined as the need for a second or a third dose of MTX or surgery. The following risk factors were compared between the two groups: serum beta-hCG on the days 1 and 4, a ≥ 15% decrease in serum beta-hCG between the days 1-4 of the treatment, age, parity, gravidity, the size of the ectopic mass and the endometrial thickness. Results: The success rate of MTX treatment was 77.1%. There were no significant dif-ferences between the two groups in regard to the age, parity, gravidity, the size of ec-topic mass and the endometrial thickness in vaginal sonography, but the mean serum beta-hCG concentration on days 1 and 4 was lower in the success group than the failure group. We also observed a ≥ 15% decrease in serum beta-hCG in 80.9% of the women from the success group and in 38.5% of the cases whose treatment had failed. The presence of fetal heart activity was seen in only one patient and this patient’s treatment failed. Two patients had previous history of ectopic pregnancy and the treatment of both ended in failure. Conclusion: Among women with ectopic pregnancies who were candidates for MTX treatment, a high serum beta-hCG concentration on the days 1-4 and also a ≤ 15% fall in

    OBJECTIVE: To assess the efifcacy of acupuncture combined with vitamin B12 acupoint injection versus acupuncture alone to reduce incomplete recovery in patients with Bell’s palsy. DATA RETRIEVAL:A computer-based online retrieval of Medline, Web of Science, CNKI, CBM databases until April 2014 was performed for relevant trials, using the key words “Bell’s palsy or idiopathic facial palsy or facial palsy” and “acupuncture or vitamin B12 or methylcobalamin”. STUDY SELECTION:All randomized controlled trials that compared acupuncture with acupuncture combined with vitamin B12 in patients with Bell’s palsy were included in the me-ta-analysis. The initial treatment lasted for at least 4 weeks. The outcomes of incomplete facial recovery were monitored. The scoring index varied and the deifnition of healing was consistent. The combined effect size was calculated by using relative risk (RR) with 95% conifdence interval (CI) using the ifxed effect model of Review Manager. MAIN OUTCOME MEASURES:Incomplete recovery rates were chosen as the primary outcome. RESULTS: Five studies involving 344 patients were included in the ifnal analysis. Results showed that the incomplete recovery rate of Bell’s palsy patients was 44.50% in the acupuncture combined with vitamin B12 group but 62.57% in the acupuncture alone group. The major acupoints were Taiyang(EX-HN5),Jiache (ST6),Dicang (ST4) andSibai (ST2). The combined effect size showed that acupuncture combined with vitamin B12 was better than acupuncture alone for the treatment of Bell’s palsy (RR = 0.71, 95%CI: 0.58–0.87;P = 0.001), this result held true when 8 patients lost to follow up in one study were included into the analyses (RR = 0.70, 95%CI: 0.58–0.86;P = 0.0005). In the subgroup analyses, the therapeutic effect in patients of the electroacupuncture subgroup was better than in the non-electroacupuncture subgroup (P = 0.024). There was no signiifcant dif-ference in the incomplete recovery rate by subgroup

    胡晓红; 孙婧; 李乔俊


    After years of general Pediatrics medicine clinical practice teaching, we have dis-covered that there exist some problems such as teachers’ job burnout, teachers’ low professional knowledge level of clinical teaching and lack of teaching ability, medical students fear, low self-esteem, psychological fear and emotional weariness breeding as well as the children patients and their parents refusal of practice because of their worrying about being a test and so on. To solve these problems, we have put forward some proposals such as to implement the management system, recognizing and rewarding teachers to affirm their teaching levels, organizing teachers to participate in academic con-ferences, seminars, and to expand their professional knowledge in order to improve their overall quality. Meanwhile, we have adopted some new teaching ways to instead of traditional ways, such as applied multimedia technology and network platforms, put emphasis on basic skills training, the im-provement of departmental rotation assessment, and other ways to improve clinical teaching quality and develop interns’ clinical thinking ability to help them transit to clinicians.%综合医院普通儿科实习教学中长期存在医生教学时间有限、意识有限和能力有限,患儿哭闹不配合,家长不信任,实习生陌生、惶恐、厌学问题。针对这3方面问题,解放军总医院第一附属医院儿科通过健全管理制度,培训带教医生理论知识和教学技巧,加强学生操作技能训练、完善出科考核等探索和实践,提高带教医生的教学能力,激发学生学习热情,提高学生临床思维、操作和解决临床问题的能力,取得了良好的教学效果。

    Santucci, Daniela; Francia, Nadia; Schwartz, Silvia; Biticchi, Roberta; Liu, Yi; Cancedda, Ranieri; Aloe, Luigi

    The conquest of space, which started with the dog Laika in 1966 to be followed few years later by Yuri Gagarin, has witnessed an increasing numbers of both vertebrates (tadpoles, frogs, rats mice etc.) and invertebrates (flies, scorpions, protozoa) species exposed to zero gravity levels. Animals are sent into orbit to proactively foresee possible health problems in humans. The issue of animal exposure to un-physiological gravity is of primary importance to i) understand behavioural and physiological adaptations in such environment as well as ii) develop coun-termeasures to improve 0-g life conditions and reduce possible animal suffering. The Mouse Drawer System (MDS), an Italian facility, has been transferred to the International Space Sta-tion with a first experiment investigating mechanisms underlying bone mass loss in microgravity in mice. Preliminary and ground-based control experiments have been conducted with six mice housed individually inside the MDS facility for 20 and 100 days. The behavioural repertoire of wild-type and transgenic mice housed in the MDS has been videorecorded with the observation subsystem, which allows to monitor animal's behavior through the use of 6 video cameras. The behavioural patterns characterizing mice in the MDS system have been finely analysed at several time points during the the experiment. Moreover, neurobiological parameters, known to be involved in the response to stress, have been evaluated. In particular, NGF and BDNF levels have been measured in the central nervous system (hippocampus, striatum, and cortex), adrenal gland and limbs. Preliminary data from ground based experiment revealed Several dif-ferences in behavioural profile between wt and tg mice, with transgenic ones apparently more active than wild type controls. Moreover a clear difference in time spent in different areas of the MDS cage was observed. Finally changes in neurotrophins levels were observed in relation to both genotype and environmental

    张峰; 王婷; 熊建荣; 陈延明


    Due to the high voltage and high current stress of the power switch in traditional single-phase Boost power factor correction ( PFC) circuit, a constant on-time ( COT) approach based on the critical mode operation of inductor current is proposed. By using the COT, the zero-voltage on main switch at low voltage level and the valley voltage on the switch at higher voltage can be rea-lized. The voltage stress of the power switch is reduced dramatically. The operation principle is also analyzed in detail, and the design proposal is discussed. Finally, a 600W PFC prototype is deve-loped. The experimental results show that the interleaved PFC converter lowers input-output ripple current and current stress of the power switch, thus the switching losses and electromagnetic inter-ference ( EMI) can be decreased.%常规单相Boost功率因数校正( PFC)电路存在功率器件电压开关应力大问题,对此提出了一种基于电感电流临界导通模式的恒定导通时间( Constant On-Time, COT)控制方法。运用COT控制策略,开关管在低压时实现零电压( ZVS)开通,高压时实现谷压( VS)开通,大大地降低了功率开关器件的电压应力。论文分析了电路的工作原理,讨论其设计方案,并研制了一台600 W样机。实验结果表明:该交错并联PFC变换器降低了输入、输出电流纹波和开关器件的电流应力,降低了变换器的开关损耗和电磁干扰。

    Object Diastolic function' s assessment is vital in order to produce information relevant to patients' functional class, management and prognosis. We sought to investigate diastolic dysfunction in essential hypertension (EH) with or without coronary heart disease (CAD) using color M- mode Doppler echocardiography and to study the relation between diastolic dysfunction and left ventricular mass index (LVMI) and geometry of LV, and to demonstrate partly the cause of increased cardiovascular risk of an echocardiographic pattern of LV geometry. Methods 36 normal subjects (Group Ⅰ) and 107 patients with essential hypertension (Group Ⅱ) were studied using color M- mode Doppler echocardiography. Four different LV anatomic adaptation to hypertension were identified by categorizing patients according to values of end-diastolic relative wall thickness (RWT) and LVMI. We measured the rate of propagation of peak early filling flow velocity (Vp), time delay (TD) of the peak early filling flow velocity from mitral tips to the apex and Vp/E. Results The geometry of LV was classified into four types according to the LVMI and RWT. The normal limits of LVMI and RWT were obtained from the upper limits of the 95 % confidence interval from mean of LVMI and RWT in healthy control group respectively, which were 115.2 g/m2 and 0.44. The definition of each type was as follows: Type Ⅰ (normal group): LVMI ≤ 115.2 g/m2 and RWT ≤0.44; Type Ⅱ (concentric remodeling): LVMI ≤115.2 g/m2 and RWT > 0.44; Type Ⅲ (eccentric hypertrophy): LVMI> 115.2 g/m2 and RWT ≤0.44; Type Ⅳ (concentric hypertrophy): LVMI >115.2 g/m2 and RWT > 0.44. Most parameters of diastolic function in each geometry type differed significantly from those in the control group, but the dif ference among each geometry type was not significant.When compared with type Ⅰ, there was a tendency thatTD was longer and Vp/E smaller in Type Ⅱ, Ⅲ and Ⅳgroups. The correlation between LVMI and Vp and TD had

Neurons and glial cells are also depolarized transiently during the phenomena. CSD is followed by a massive increase in glutamate release and by changes in the brain microcirculation. The aim of this study was to investigate the effects of two N-methyl-D-aspartate receptor antagonists, endogenous kynurenic acid (KYNA and dizocilpine, on CSD and the related blood–brain barrier (BBB permeability in rats. In intact animals, KYNA hardly crosses the BBB but has some positive features as compared with its precursor L-Kynurenine, which is frequently used in animal studies (KYNA cannot be metabolized to excitotoxic agents such as 3-hydroxy-L-kynurenine and quinolinic acid. We therefore investigated the possible effects of peripherally administered KYNA. Repetitive CSD waves were elicited by the application of 1 M KCl solution to the cortex. Direct current-electrocorticograms were measured for 1 hour. Four parameters of the waves were compared. Evans blue dye and fluorescent microscopy were used to study the possible changes in the permeability of the BBB. The results demonstrated that N-methyl-D-aspartate receptor antagonists can reduce the number of CSD waves and decrease

  15. Process optimization of rare earth and aluminum leaching from weathered crust elution-deposited rare earth ore with compound ammonium salts

    何正艳; 张臻悦; 余军霞; 徐志高; 池汝安


    In order to intensify the leaching process of rare earth (RE) and reduce the impurities in the leachate, ammonium chloride (NH4Cl) and ammonium nitrate (NH4NO3) were mixed as a compound leaching agent to treat the weathered crust elution-deposited RE ore. Effects of molar ratio of NH4Cl and NH4NO3, ammonium (NH4+) concentration, leaching agent pH and flow rate on the leaching process of RE were studied and evaluated by the chromatographic plate theory. Leaching process of the main impurity alu-minium (Al) was also discussed in detail. Results showed that a higher initial ammonium concentration in a certain range could en-hance the mass transfer process of RE and Al by providing a driving force to overcome the resistance of diffusion. pH almost had no effects on the mass transfer efficiency of RE and Al in the range of 4 to 8. The relationship between the flow rate and height equiva-lent to a theoretical plate (HETP) could fit well with the Van Deemter equation, and the flow rate at the lowest HETP was determined. The optimum conditions of column leaching for RE and Al were 1:1 (molar ratio) of NH4Cl and NH4NO3, 0.2 mol/L of ammonium concentration, pH 4–8 of leaching agent and 0.5 mL/min of flow rate. Under this condition, the mass transfer efficiency of RE was improved, but no change was observed for Al compared with the most widely used ammonium sulfate. Moreover, the significant dif-ference value (around 20 mL) of retention volume at the peak concentration between RE and Al provided a possibility for their sepa-ration. It suggested the potential application of the novel compound leaching agent (NH4Cl/NH4NO3). It was found that the relative concentration of RE in the leachate could be easily obtained by monitoring the pH of leachate.

  2. 韩语因果复句在汉语中的对应研究%A Correspondence Analysis of the Causational Claus-es in Chinese and Korean



    Causational clauses exist both in Chinese and Korean, but these two languages belong to different families, resulting in great dif-ferences in techniques of expression and conjunctive devices. Korean causational clauses are correspondent not only to Chinese ones but also to other semantic clauses or forms. Causational clauses are studied widely in the research of general theories. However, few studies are based on Korean-Chinese translated novel corpus. This paper attempts to study causational clauses with actual bilingual examples taken from Korean-Chinese equivalent translational novel corpus. The compara-tive analysis of Chinese corresponding forms of causational clauses “-어서、-니까、-느라고、-므로” frequently used in Korean, is a good reference that may enlighten the study and teaching of Chinese- Koreancausational clauses.%中韩两种语言都存在因果复句,但因这两种语言分属不同语系,所以它们在复句的表现方法及连接手段上都有着很大差异,韩国语的因果复句不仅和汉语的因果复句相对应,而且还能和其他语义关系的复句或其他表现形式相对应。先行研究成果当中极少运用中韩对译小说语料库来研究复句的情况,尝试利用韩中对等翻译小说语料库进行复句研究,运用实际双语例句、使用比较分析法进行考察分析韩国语中使用频率较高的“-어서”、“-니까”、“-느라고”、“-므로”①等因果复句在汉语中的对应形式,这对于中韩复句的研究及教学将是一个很好的启示和参考。

  3. Characterization of Different Land Classes and Disaster Monitoring Using Microwave Land Emissivity for the Indian Subcontinent

    Saha, Korak; Raju, Suresh; Antony, Tinu; Krishna Moorthy, K.

    Despite the ability of satellite borne microwave radiometers to measure the atmospheric pa-rameters, liquid water and the microphysical properties of clouds, they have serious limitations over the land owing its large and spatially heterogeneous emissivity compared to the relatively low and homogenous oceans. This calls for determination of the spatial maps of land-surface emissivity with accuracies better than ˜2%. In this study, the characterization of microwave emissivity of different land surface classes over the Indian region is carried out with the forth-coming Indo-French microwave satellite program Megha-Tropiques in focus. The land emissivity is retrieved using satellite microwave radiometer data from Special Sensor Microwave/Imager (SSM/I) and TRMM Microwave Imager (TMI) at 10, 19, 22, 37 and 85 GHz. After identify-ing the clear sky daily data, the microwave radiative transfer computation, is applied to the respective daily atmospheric profile for deducing the upwelling and downwelling atmospheric radiations. This, along with the skin temperature data, is used to retrieve land emission from satellites data. The emissivity maps of placecountry-regionIndia for three months representing winter (January) and post-monsoon (September-October) seasons of 2008 at V and H polar-izations of all the channels (except for 22 GHz) are generated. Though the land emissivity values in V-polarization vary between 0.5 and ˜1, some land surface classes such as the desert region, marshy land, fresh snow covered region and evergreen forest region, etc, show distinct emissivity characteristics. On this basis few typical classes having uniform physical properties over sufficient area are identified. Usually the Indian desert region is dry and shows low emis-sivity (˜0.88 in H-polarisation) and high polarization difference, V-H (˜0.1). Densely vegetated zones of tropical rain forests exhibit high emissivity values (˜0.95) and low polarization dif-ference (lt;0.01). The

    Full Text Available 210 years ago Nagyváthy János published the first systematic, agricultural trade book, called ’Diligent Farmers’ in Hungarian in Pest. This outstanding person of our agricultural history was born on 19th January 1755, in Miskolc. After leaving the Protestant secondary grammar school in Miskolc, he studied law and theology in Sárospatak. At the Protestant secondary grammar school in Losonc he became a ’Subrector’, that is, the the teacher of poetry. Due to a serious illness affecting his eyes he left this job and went to Pest for medical treatment. During the long therapy he visited the lectures of Mitterpacher Lajos, who was the most excellent theoratical agricultural specialist in the country. In 1782 he took military service for four years, in the Duka cavalry regiment, where he reached the rank of a captain and he was garrisoned in Belgium, Italy and Austria. As a commisariat officer he got to know the more developed agriculture of Europe, and it was at that time that he studied agricultural technical literature. In 1786 he had a relapse of his eye disease therefore he left the army and tried to find a cure in Vienna. Here he got acquainted with Jordán Péter, director of the domains of the court, who employed him as an assistant. During the time he spent in the domain of Vöslau, he could completed his academic knowledge with practical experience. In 1788 he moved to Pest where he made friends with Kazinczy, Batsányi, Verseghy and Széchenyi Ferenc, who were the representatives of the most progressive group of nobility. He became the member of the ’Magnanamitas’ Masonic Lodge. In 179o he published four pamphlets anonymously called ’ The change of religion’, ’Civil prediction from the stars’, ’The red friend’, ’Hours of joy in the life of a true Hungarian patriot’. In 1791 he published ’The diligent farmer’ in two volumes on 1213 pages recommending it to the ’sweaty Hungarian farmer’. In this book he wrote about all his

  6. 从翻转课堂到翻转会议--O2O环境中学术会议的组织模型及技术支撑体系研究%From Flipped Classroom to Flipped Conference:A Study on Academic Conference Mode and Its Technology-Supported Platform in O2O Environment

    宋述强; 高宣; 钟晓流


    With the development of educational insights and information technology, flipped classroom based on the O2O (Of-fline-to-Online) environment has been a hot topic in the current educational research. As a particular activity disseminating informa-tion and sharing knowledge, academic conference has tremendous similarities with in-class teaching. Based on the notion of flipped classroom, the concept of flipped conference is put forward in the paper. The paper reviews the concept and origin of academic con-ference, and studies the implementation of the two cases of flipped conference at home and abroad respectively. On the basis of “Tai chi Ring Mode I”in the previous research on flipped classroom, the author establishes “Tai chi Ring Mode II” for flipped conference. Similar to the flipped classroom, the effectiveness of flipped conference strongly relies on various technical supports of the informa-tion-based hardware and software platforms in O2O environment. At the end of the paper, the author systematically introduces the technical platform system which supports the flipped conference according to his own practical experience. By explaining the theoreti-cal concepts, organizational patterns and technical platform of the flipped conference, the author attempts to provide practical guid-ance for the effective organization and the innovative development in the academic conference under the environment of O2O.%随着教育理念和信息技术的发展,基于O2O环境的翻转课堂已成为当前教育教学领域的研究热点与实践趋势。作为信息传播、问题探讨和知识扩散的特定活动,学术会议与课堂教学有着诸多类似的方面。为此,借鉴翻转课堂的理念提出了翻转会议的概念,并剖析了国内外两次翻转式学术会议的组织案例。并在前期研究成果---面向翻转课堂的“太极环模型I”的基础上,构建了面向翻转会议的“太极环模型II”。与翻转课堂一

  7. Live and Prerecorded Popular Music Consumption%从现场音乐与录制音乐看流行音乐的市场需求

    Juan D. Montoro-Pons [西班牙; 马绯璠(编译); Manuel Cuadrado-Garcia


    最近十年来,随着人们消费习惯的改变,流行音乐市场也发生了很大变化,现场音乐的市场份额不断增加。本文从现场音乐和录制音乐两个方面分析了流行音乐市场需求,采用的数据来自20(0--2037年度西班牙“习惯与文化行为调查”,通过双变量profit模型来分析现场音乐会的上座率和录制音乐的销售情况。通过分析,我们可以大致描述出两个市场中一般消费者和消费频率较高的消费者大致情况。分析结果显示,两种消费者存在一些相似的方面,这主要表现在性别和文化素养对音乐消费的作用;但同时也存在一些十分显著的差别,这主要表现在时间限制、与经济活动的关系和技术利用这三个方面。最后,我们发现,录制音乐消费和现场音乐消费具有一定的互补性,具有直接的因果关系,这可以解释近年来音乐市场组织制度上发生的一些变化。%Changing consumption habits have rearranged the popular music market in the last decade, and a pattern in which live music attendance gets an increasing share of the market has emerged. This work analyzes the demand for the popular music sector considering its double dimension as supplier of live concerts and prerecorded music. We use the 2006/2007 wave of Spain' s Survey on Habits and Cultural Practices, and estimate a bivariate pmbit model for attendance to live concerts and the ourehase of orere- corded music. Results allow us to describe the profile of the average and frequent consumer in both mar- kets, which shows some similarities-gender effects and the role of cultural capital - but also striking dif- ferences-time restrictions and relation to economic activity, and the use of technology. Finally, we find evidence of demand complementarities, with a direct causal link from prerecorded music to live atten- dance that helps explain recent institutional changes.

  13. 基于动力反演方法的亚洲季风机制探讨%The Exploring of the Asian Monsoon Driving Mechanism Based on Dynamical Inversion Method

    李玉霞; 林振山; 刘会玉


    The monsoon driving mechanism is a hot spot in the quaternary global change research, where the in-ternational academia has been paid close attention. As early as in 1686, Halley has put forward that the heat dif-ferences caused by the sun between the marine and terrestrial bring about the monsoon. With the deepening of the research, different driving factors are proposed one after another, such as the solar activity, the mechanical force and thermal effect of the Qinghai-Tibet Plateau, ENSO, the temperature of the south and north poles, the migration of the intertropical convergence zone, the thermohaline circulation and so on in which the solar activ-ity and the thermohaline circulation are widely accepted. Cave stalagmites oxygen isotope is one of the most important high-resolution alternative indexes of palaeoclimate. Especially in the region strongly affected by the monsoon, the change of the values of stalagmiteδ18O is often taken as the index of ancient monsoon intensi-ty. The Asian monsoon is an important part of the global climate system. Usually the Asian monsoon can be di-vided into East Asia monsoon and Indian monsoon, but the two monsoon regions have no clear boundary. So it is hard to verdict which monsoon the stalagmite collected from this convergence zone represents. Dongge cave is just located in the convergence zone, as is mentioned above,and which monsoon the stalagmiteδ18O value of Dongge Cave represents is still controversial. By means of the dynamic inversion analysis of the Asian mon-soon, the following results are obtained:1) The stalagmitesδ18O value of Dongge Cave is more likely to repre-sent the Indian monsoon. The Indian monsoon system is a complex nonlinear dynamic system driven by the Antarctic temperature and other factors. 2) The solar activity plays a negative feedback stabilizing role in the Indian monsoon system. The stronger the solar activity is, the weaker the stabilization role it plays will be. The temperature of the

    郝俊杰; 刘佳中; 孙静; 谢淑娜; 王婧; 王静


    To evaluate several fungicidal seed treatments(azoxystrobin, fludioxonil, mefenoxam, and captan) a-gainst three Fusarium species(F. graminearum, F. verticillioides and F. proliferatum) that infect maize seed or seedlings, we conducted experiments using a petri plate assay in the laboratory and a potting medium in the natural conditions. In the laboratory experiments, the results of analysis of variance showed the other effects besides the vari-ety × seed treatments interactions were all significant(P≤0.05). In the potting medium experiments, only the isolate effects of the several traits were significant. Both evaluation methods identified that the F. graminearum isolate ap-peared to be more aggressive than both the isolates of F. verticillioides and F. proliferatum. In the potting medium ex-periments, there were no significant differences among the seed treatments, although individual fludioxonil was the relative effective treatment from the untreated control according to root length and dry weight. In the laboratory experi-ments, the results demonstrated that fungicide seed treatments containing fludioxonil and captan had significant dif-ferences from the untreated control, and the individual fludioxonil was the most effective among the fungicidal seed treatments in terms of preventing fungal colonization and decay of the seeds and radicles. In the laboratory experi-ments, there also were differential effects of the fungicides against individual Fusarium isolates. All the fungicides a-gainst F. graminearum had less effective than the other two Fusarium isolates. Overall, the use of individual fludioxonil was the most effective, and azoxystrobin was the least effective against different Fusarium species.%采用室内培养皿法和室外盆栽两种方法,分析杀菌剂种子处理(嘧菌脂、咯菌腈、精甲霜灵、克菌丹)单独和复合使用对特定镰孢菌种(禾谷镰孢菌F. graminearum、轮枝镰孢菌F. verticillioides

    The field trials were conducted at two sites nearby the Tropical Center to investigate the influence of variety and fer-tilization on dry matter formation and accumulation of cassava. Two varieties of newly developed SC5 and conventional SC205 were used with five fertilization treatments including NP (1.0:0.4:0), NK (1:0:1), PK (0:0.4:1.0), NPK (1.0:0.4:1.0) and CK (no fertilizer application). Results indicated that the dry matter accumulation patterns were similar for both varieties. From transplant-ing to early August, dry matter accumulation mainly allocated in above-ground parts. When tubes started rapidly growing from mid August, the allocation of dry matter accumulation was shifted from above-ground to underground parts, and there was a dif-ference between two varieties in accumulating velocity and distributing proportion of biomass. SC5 had larger crown with many earlier developing branches and leaves compared with SC205, resulting in more biomass accumulation in above-ground parts, thus reducing harvesting index. For fertilizer application, N was the most significant factor to increase dry matter, following K and P. Combining application of NPK (1.0:0.4:1.0) significantly enhanced accumulating velocity of dry matter and tube yields of cas-sava. There were some difference between two varieties in dry matter accumulation depended on NPK fertilizer application, and probably related to their nutrient demands and root developing level.%  以传统品种华南205及新育品种华南5号为材料,通过田间试验,研究了木薯生物量与产量累积规律,探讨了品种改良及施肥措施对木薯物质形成规律的影响.结果表明,不同品种生物量累积动态相似,生长前期生物量累积缓慢,且以地上部分为主,到8月中下旬块根快速生长,物质累积速率迅速提高,累积重心由地上部逐渐转移到地下部;不同品种间物质累积速率及分配比例有所差异,分枝早且多、茎

  11. On the Methods of Translating Chinese Philosophical Classics into English%论中国哲学典籍英译方法



    中国哲学典籍的英译方法可以细分为诠释的方法和转换的方法两个部分。诠释的方法以朱熹对儒家经典的诠释为例,借助黄俊杰先生提出的“概念史的研究方法”和“思想史的研究方法”,主要探讨了中国哲学典籍英译过程中的经典诠释方法:一方面侧重语言性的分析,对核心概念的训诂及其在哲学发展史流变过程中不断丰富的内涵的把握;另一方面侧重对诠释者的“历史性”的分析,把握诠释者在不同的时空情景下的诠释言论的具体意义。转换的方法,则借助安乐哲比较哲学的研究方法,特别是具体的“策略性框架”,首先在认识论上要避免西方文化中心主义的负面影响,从而看到中国哲学与西方哲学的差异性和平等地位,在此基础上促进中西方哲学的互惠互动。在方法论上,从元典出发,构建相关的哲学语境,再在该语境中进行文本的翻译和转换,特别是对关键哲学术语的翻译,一定要体现中国哲学思想和语言的特质,而不是有意无意地强加上西方文化的预设。%Two methods are involved in the translation of Chinese philosophical classics into English:interpretation and trans-ference.In the process of interpretation,this paper adopts Huang Junjie′s method of interpreting the kernel concepts in philo-sophical history,taking Zhuxi′s interpretation and annotation on the“Four Books”as an example,focusing on the analysis of its meaning of difference and richness;on the other hand,it is a method of interpreting the influence of the interpreter′s historical background on the specific meaning of classics.In the process of transference,this paper takes the perspective of Roger Ames′“comparative philosophy”to make further study on the transferring method of Chinese philosophy into English.First of all,on epistemology,we should try to avoid the ethnocentrism of western countries

    To determine the concentrations of lanthanum chloride (LaCl3) in medium and compare the dif-ference between leaf and root in cold resistance ofCymbidium plantletsin vitro, the effects of lanthanum ions on cold resistance of plantlets based on natural cooling treatment were studied. Seven indexes related to cold resistance including MDA content, membrane permeability, soluble protein content, soluble sug-ar content, SOD activity, POD activity and CAT activity of leaf and root weredetermined. The results showed that the optimum concentration of LaCl3 to improve cold resistance ofC.hybridumplantletsin vi-tro was 20 mg·L-1. High concentrations of LaCl3 (60 mg·L-1) had negative effects on the cold resistance. MDA and membrane permeability signiifcantly relfected the cold resistance and could be the indexes in Cymbidium plantletsin vitro. Each concentration of LaCl3 improved thecold-resistance differently. The cold-resistance improvement of LaCl3 on aboveground and underground showed inconsistency between different indexes.%采用自然降温处理,研究稀土镧(LaCl3)对大花蕙兰组培苗耐寒性的影响,确定培养基中加入La3+的浓度,比较地上部和地下部在反映组培苗耐寒性能方面的差异性。分别测定了地上部和地下部中丙二醛(MDA)含量、膜透性、可溶性蛋白(SP)、可溶性糖(SS)、超氧化物歧化酶(SOD)、过氧化物酶(POD)和过氧化氢酶(CAT)7项与耐寒性有关的生理指标。结果表明, La3+提高大花蕙兰组培苗耐寒性的最适宜浓度为20 mg·L-1,浓度过高(60 mg·L-1)出现负效应。膜脂过氧化产物丙二醛(MDA)含量和细胞膜透性两项指标在反应大花蕙兰组培苗耐寒性作用明显,可作为其耐寒性鉴定指标。各浓度LaCl3处理对大花蕙兰组培苗耐寒性的提高差异明显, LaCl3对地上部和地下部耐寒性的提高在不同指标间表现出不一致性。

  19. 韩国中等强国外交的效果为何有限?%The South Korea's Middle Power Diplomacy Operations



    韩国开展中等强国外交是基于自身独特的地缘位置、综合实力的考虑。为了推进统一外交、增强地区影响和提升国际地位,韩国积极通过国际倡议外交、国际贡献外交、国际会议外交、文化外交等多种方式推进其中等强国外交。近年来,韩国历届政府都不遗余力地推动韩国的中等强国外交,比较典型的案例有卢武铉时期的“东北亚均衡者”构想、李明博时期的“新亚洲倡议”和朴槿惠时期的“东北亚和平合作构想”。不过韩国中等强国外交的效果并不理想,美韩联盟限制了韩国开展独立外交的能力,而大国环抱的地缘特点也使得韩国外交面临着大国权力政治的巨大束缚,总统任期有限更是导致其中等强国外交缺乏延续性。对于韩国的中等强国外交而言,必须立足于东亚的现实情况,发挥韩国中等国家的经济优势,做好搭台者、协调者,同时要减少政府更迭对中等强国外交的影响,增强战略延续性。%South Korea's middle power diplomatic practice is based on its unique geographical location and comprehensive strength.In order to advance its unified diplomacy, enhance its regional influence, and im-prove its international status,South Korea actively promotes its middle power diplomacy strategy in many different ways like international agenda initiatives, international contributions diplomacy, international con-ference diplomacy and cultural diplomacy.In recent years, the Korean administrations have spared no effort to promote South Korea's middle power diplomacy.The typical cases include“balancer in Northeast Asia”during Roh Moo-hyun administrations, “New Asia Initiative” during Lee Myung-bak administrations and“vision of peace and cooperation in Northeast Asia” during Park Geun-hye period.But the effect of South Korea's middle power diplomacy is not ideal, the US-ROK alliance, power struggle among

  8. Hybrid iterative equalization algorithm based on precoding matrix%基于预编码的混合迭代均衡算法

    李一兵; 刘海涛; 叶方; 林云


    To address co⁃antenna and multipath interferences in the LTE downlink multi⁃input multi⁃output orthogo⁃nal frequency division multiplexing communication system, we propose a low⁃complexity hybrid iterative equaliza⁃tion algorithm. In a receiving terminal, the proposed algorithm utilizes a precoding matrix to spread symbols over all subcarriers, which relieves the influence of deep fading in some parts of the subcarriers. In a receiver, the soft in⁃terference elimination algorithm is adopted based on the minimum mean⁃square⁃error ( MMSE)⁃sorted QR decompo⁃sition to avoid complexity when solving an inverse matrix. This matrix is always involved in traditional parallel soft interference elimination equilibrium algorithms based on minimum mean square error ( MMSE) equalization. In ad⁃dition, using a channel arrangement, the soft interference elimination algorithm prioritizes the detection of transmis⁃sion symbols with a maximum noise⁃to⁃signal ratio ( SNR) to improve detection accuracy. Furthermore, the recon⁃structed signals is preprocessed by a precoding matrix, which decreases error propagation in iteration processing. Simulation results show that the performance of the proposed algorithm is better than that of existing iterative inter⁃ference cancelation algorithms. Specifically, when the system is equipped with four transmitters and four receivers, the bit error rate is 10-5 and the SNR is improved by approximately 0.7 dB.%针对LTE下行多输入多输出正交频分多址( MIMO⁃OFDM)系统中的天线间干扰和多径干扰问题,提出一种低复杂度的迭代均衡算法。该算法在接收端通过预编码矩阵将发射信号扩展到所有子载波上,从而减少部分子载波深衰落对扩展前原始发射信号的影响。算法在接收端引入最小均方差误差排序QR分解( MMSE⁃SQRD)软干扰消除均衡算法,一方面避免传统基于最小均方误差( MMSE)并行软干扰消

  5. Numerical simulation of the tip leakage flow in a ducted propulsor based on the RANS method%基于RANS方法的导管推进器梢隙流动数值模拟

    阮华; 张志荣; 辛公正


    In this paper, a ducted propulsor is taken as the object of the research, where the RANS simulation method is used to study the tip leakage flow of the propulsor. Through the applicability study of the numerical grid type and the turbulence model, and by analyzing the flow field at the tip region, preliminary numerical methods based on RANS for tip leakage flow are finally proposed, and the corresponding results agree well with the experimental data. Through the comparison of unstructured and structured mesh's results, it is ob-served that structured mesh can capture more flowing detail (for example, the boundary flow). Therefore, the structured mesh is more appropriate for the numerical simulation of tip leakage flow. Meanwhile, three turbulence models, SST k-ω, RNG k-ε, and RSM are used, and their numerical results are essentially similar, which suggests that all three can be applied in the tip leakage flow simulation. Through the analysis of tip clearance region's flow field, it is found that tip leakage flow's driving power is primary the pressure dif-ference between the front and back side of the rotor, and the flow is affected by the wall boundary flow. When the flow enters the tip gap, flow separation is occurred, and a gap separation vortex is formed. The tip clearance flow goes across the gap and interacts with the passage flow, finally developing into Tip Leakage Vortex (TLV). TLV's inception position is about 37.5% cord length and attaches to the rotor wall, and then sheds from the rotor wall at approximately 75%cord length into the wake flied. The numerical results clear-ly demonstrate the changing process of the tip leakage vortex inception, development, and shedding.%以导管推进器为研究对象,采用雷诺时均纳维斯托克斯(RANS)方法对其梢隙流动进行数值模拟研究.通过对网格类型、湍流模型的适用性研究以及对梢部流场的研究探讨,初步建立了基于RANS梢隙流动的数值模拟方法;数值计

    Effect of plant fermentation extracts (PFE) on immune functions in mice was investigated. Male BALB/c mice were randomly divided into four groups and orally administered a plant fermentation extracts (PFE) at daily dosages of 1.25, 2.50, 5.00 mL/kg·BW (comparatively as 2.5, 5, 10 times of recommended human daily dosage) respectively. Normal saline was used as the control. After 4 weeks, indexes of non-specific and specific immunity function in mice were examined. Compared with the control, plant fermentation extracts significantly increased the thymus index, improved the abilities of carbon particle clearance and peritoneal macrophage phagocytizing chicken red blood cells. The killing activity of NK cells, the level of serum lysozyme and hemolysin, and the productive ability of antibody forming cells were also greatly increased. No obvious dif-ferences in the bodyweight, spleen index, con A-induced splenic lymphocyte proliferation and the ability of de-layed type hypersensitivity induced by SRBC were observed in our study. These results indicated that the plant fermentation extracts (PFE) had no obvious impact on cellular immunity, but significantly strengthen the non-specific immune function and humoral immunity in mice. Overall, plant fermentation extracts (PFE) possess enhancing immunity property.%研究植物发酵液(酵素)对机体免疫功能的影响。将雄性BALB/c小鼠随机分为低、中、高剂量及对照组,分别经口给予1.25、2.5、5.0 mL/kg·BW(相当于人推荐日服量的2.5、5、10倍)植物发酵液及生理盐水。连续灌胃4周后,对小鼠非特异性免疫功能和特异性免疫功能有关指标进行测定。植物发酵液(酵素)能明显提高小鼠胸腺指数,显著增强小鼠的碳廓清能力、腹腔巨噬细胞吞噬鸡红细胞功能,明显提高NK细胞杀伤活性,显著升高小鼠血清溶血素、溶菌酶水平,促进抗体生成细胞增殖,对小鼠的

Iran J Child Neurol. 2014 Winter; 8(1:1-11.ObjectiveAs acute liver failure (ALF and chronic liver disease (cirrhosis continue to increase in prevalence, we will see more cases of hepatic encephalopathy.Primary care physician are often the first to suspect it, since they are familiar with the patient’s usual physical and mental status. This serious complication typically occurs in patients with severe comorbidities and needs multidisciplinary evaluation and care. Hepatic encephalopathy should be considered in any patient with acute liver failure and cirrhosis who presents with neuropsychiatric manifestations, decrease level of consciousness (coma, change of personality, intellectualand behavioral deterioration, speech and motor dysfunction.Every cirrhotic patient may be at risk; potential precipitating factors should be addressed in regular clinic visits. The encephalopathy of liver disease may be prominent, or can be present in subtle forms, such as decline of school performance, emotional outbursts, or depression.“Subtle form” of hepatic encephalopathy may not be obvious on clinical examination, but can be detected by neurophysiologic and neuropsychiatric testing.References:Ferenci P, Lockwood A, Mullen K, Tarter R, Weissenborn K, Blei AT.

    Objective Analyze the clinical outcomes of arthroscopic anterior cruciate ligament (ACL) reconstruction with bone patellar tendon bone (B-PT-B) allograft or autograft. Methods A total of 107 patients underwent same arthroscopie ACL reconstruction technique were randomized into three groups (A: autograft 36, B: non-irradiated deep-frozen allograft 36, C: irradiated allograft 35). Before surgery and at follow-up, patients were evaluated by general conditions, pivot shift test, Lachman and Anterior Drawer Test (ADT), KT-2000 arthrometer testing, Daniel one-leg hop test, overall IKDC rating, Lysholm and Tegner activ-ity score. Results A total of 103 patients were available for full evaluation. The mean follow-up time of A, B and C groups were 39.5, 36.3 and 37.6 months respectively. 1) In A group, patellar fracture occurred in 1 patient and anterior knee pain occurred in 2. In B group, 1 patient had late septic infection. Patients in the B and C groups underwent shorter operation time and longer fever time. There was no difference between the three groups in hospital stay time. 2) According to pivot shift test, Lachman test, ADT, and KT-2000 arthrom-eter testing, differences were found between C group to A or B groups, while no statistically significant dif-ferences between A and B groups. The failure rate in C group (36%) was higher than that with A (8%) and B group (9%). According to Daniel one-leg hop test, the overall IKDC, Lysholm and Tegner activity score, no differences were found between the three groups. Conclusion Patients underwent ACL reconstruction with B-PT-B non-irradiated deep-frozen allograft or autograft had similar clinical outcomes. Non-irradiated B-PT-B allograft is a reasonable alternative to autograft. While the anterior and rotational stability decreased signifi-cantly, when irradiated B-PT-B allograft was used.%目的 比较自体与γ射线照射和非照射异体骨-髌腱-骨(bone patellar tendon bone,B-PT-B)重

    吴娜娜; 钱虹; 郑璐; 李亚峰


    Nitrogen deposition is one of the major environmental factors affecting the biogeochemical cycles of terrestrial biogenic elements. The increase of nitrogen deposition may increase the carbon storage in the litter and soil. In this study, earthworm species and density were investigated by hand picking method and square soil sampler in a mixed broad-leaf Korean pine forest in Changbai Mountain, China after 6 years of N addition (ambient+N50 kg·hm-2·a-1) treatment. Meanwhile, litter and soil layer of organic carbon and nitrogen content were determined by an element analyzer. The results of the study showed that in control and nitrogen addition plots, earthworm species and density distribution pattern was similar. The 4 species of earthworms were observed. Eiseniafoetida and Pheretima sp. were epigeics. Drawidachangbaiensis was endogeics and anecics. Enchytraeidae spp. was earthwomenchytraeidae larvae. Among them, the density of Eiseniafoetida was the largest, and it could reach 25 individuals·m-2. The density of Drawida-changbaiensis was 6 individuals·m-2, and the density of Pheretima sp. was smallest. The total density of three functional groups was 23 individuals·m-2 in the control plots and 31 individuals·m-2 in the nitrogen plots, respectively. Thus, there were no significant dif-ferences (P=0.238) in the species and density of earthworms in control and nitrogen addition plots in Changbai Mountain. In the four layers of litter and soil, the total carbon was not affected by nitrogen addition, and total nitrogen was not significantly changed. The results improve our ability to estimate carbon sequestration potential of forest soil and build a global carbon cycle model under future climate change especially elevated N deposition.%氮沉降是影响陆地生源要素生物地球化学循环的主要环境因子之一。以往对凋落物和土壤有机碳降解过程中分解者的作用研究主要集中在微生物方面,而对土壤动

  10. Decomposition of Interference Hyperspectral Images Using Improved Morphological Component Analysis%基于改进MCA的干涉高光谱图像分解

    温佳; 赵军锁; 王彩玲; 夏玉立


    As the special imaging principle of the interference hyperspectral image data ,there are lots of vertical interference stripes in every frames .The stripes’ positions are fixed ,and their pixel values are very high .Horizontal displacements also exist in the background between the frames .This special characteristics will destroy the regular structure of the original interference hyperspectral image data ,which will also lead to the direct application of compressive sensing theory and traditional compression algorithms can’t get the ideal effect .As the interference stripes signals and the background signals have different characteristics themselves ,the orthogonal bases which can sparse represent them will also be different .According to this thought ,in this paper the morphological component analysis (MCA) is adopted to separate the interference stripes signals and background signals .As the huge amount of interference hyperspectral image will lead to slow iterative convergence speed and low computational efficien‐cy of the traditional MCA algorithm ,an improved MCA algorithm is also proposed according to the characteristics of the inter‐ference hyperspectral image data ,the conditions of iterative convergence is improved ,the iteration will be terminated when the error of the separated image signals and the original image signals are almost unchanged .And according to the thought that the orthogonal basis can sparse represent the corresponding signals but cannot sparse represent other signals ,an adaptive update mode of the threshold is also proposed in order to accelerate the computational speed of the traditional MCA algorithm ,in the proposed algorithm ,the projected coefficients of image signals at the different orthogonal bases are calculated and compared in order to get the minimum value and the maximum value of threshold ,and the average value of them is chosen as an optimal threshold value for the adaptive update mode .The experimental results

  11. Spatiotemporal Pattern of Gold Content of GDP at Prefecture Level or Cities Above in China%中国地级及以上城市GDP含金量时空分异格局



    Gold content of GDP is an international general index to reflect the improvement of people's liveli-hood. For decades China's GDP and per capita GDP have been growing rapidly. However, the cost of high growth in GDP including the waste of resources, environmental pollution, urban-rural income gap, slowly rise of living standard and so on.The fundamental goal of economic growth is human all-round development. There will be real meaning that economic growth must be translated into upgrading the level of benefits of the over-whelming majority of residents. Only a reasonable income vs. GDP ratio can have reference value for the econ-omy at large. Taking the gold content of GDP as the measuring indicator, this article analyses the global trends, spatial heterogeneities and correlations of gold content of GDP for 343 cities at the prefecture level or above with panel data in 2001 and 2011 with exploratory spatial data analysis methods, of Moran's I and Getis-Ord Gi*, whereby the significance of spatial interactions and geographical location was investigated. Semi-variant function, gravity center migration and trend surface analysis was used to explore the spatiotemporal spatial pat-terns of the gold content of GDP over the 10 years with the application of ArcGIS10.0 and GeoDa095i. Influ-encing factors of gold content of GDP were tried to summarize. The results show as following:The spatial dif-ference of gold content of GDP is significantly, showing a trend of the western China>the eastern China>the middle China, and the North>the South>the Central. The calculate result of Moran's I shows that the density of gold content of GDP at prefecture level or above cities in China has a growing global spatial autocorrelation characteristic, regional disparities trend of gold content of GDP is more and more obvious. The gravity center of gold content of GDP had moved southeast on the whole from 2001 to 2011. The north of the Yellow River and the south of the Changjiang River are

    The traditional econometric model is mostly utilized in water resources vulnerability assessment field. In recent years, the author and his research teams have studied the water resources vulnerability problem in Hengyang Basin using the traditional method. In order to explore better water resources vulnerability quanti-tative assessment method, in this article, GIS and RS technology was used to evaluated the vulnerability of wa-ter resources system in Hengyang Basin. Using GIS/RS method, take Hengyang Basin as the research region, construct a water resource vulnerability evaluation index system based on GIS and RS which contains natural vulnerability (NV), human vulnerability (HV) and burden vulnerability (BV) three aspects and include aver-age precipitation, drought index during 7-9, slope index, soil water storage ability index, vegetation index, land use index, water availability index and human activity index 8 specific index. The index system has great dif-ferences to the indicator system of the traditional method. Firstly, use the human activity index to replace the series of index in original social and economic aspects of the traditional method. Secondly, increase water re-sources availability index and land use index to replace series of indicators about artificial vulnerability index in traditional method. Eight thematic data layers were generated after index data digitization and layer edit pro-cessing. Water resource vulnerability of Hengyang Basin was calculated using the spatial analysis model. The results show that water resources system vulnerability space distribution shows the situation of "north and south low, middle high", Hengyang in the north, Qidong in the west and Hengnan in the centeris the highest water resource vulnerability areas. And LeiYang in the sourth, and Hengdong in the northeastis the water re-source vulnerability low value areas. The evaluation results have good similarity between water resource vul-nerability evaluation method

    通过搜集和处理互联网中的关键词数据,本文测度了在产业发展和区域创新两个方面的长三角城市网络空间体系,并研究了长三角城市之间的网络协作关系。研究表明,网络信息空间中的长三角城市网络与传统的城市网络存在较大差异,主要体现在中小城市表现活跃,以及平面化网络特征。但本文的分析也表明,城市地理区位、地理邻近性及网络信息传播的特征是影响网络信息空间中的城市网络的主要因素。总的来说,网络信息空间中的城市网络形成是一个复杂机制的结果,在信息传播和基础地理条件等各种因素的相互作用中持续演化。%With the development of Internet and information technology, cy-berspace, a virtual space, has appeared in the geographic research area in ad-dition to a physical space. In cyberspace, information can be produced, spread and received in almost one second, while such a process still rely on infras-tructures in physical space. Due to that, some geographic phenomena may per-form distinctively between cyberspace and physical space. Hence, there may be some new discoveries, both in theoretical and practical aspects, if differ-ences between two spaces could be studied. From last century, there have been geographers who have studied the European and American cities networks through immigrants, traffic flows, goods flows and other indicators which can be mea-sured in physical space. Until now, there are also some geographers putting their attention on cities networks in cyberspace, including Castells, Zook and so forth, whose researches inspire the paper a lot. Under such a background, the paper focus on cities network in Yangtze-River Delta, exploring the dif-ference between cyberspace and physical space and causes behind it. The paper chooses two key issues in future development of Yangtze-River Delta cities (as The Planning of Yangtze-River Delta Region in The

    The purpose of this article is to study the influence of industrial structure on the economic inequali-ties among counties at the less developed Yunnan Province in China. In the process of modernization, the coun-try economy is the basic element of national economy and the ties of city with rural economic. Nowadays, Chi-nese economic operation of the prominent contradictions such as the regional inequality mostly is reflected in regional scale at countries. Therefore, it is necessary to discuss the county economic difference in order to coor-dinate regional development. Yunnan as a frontier, ethnic, mountainous and poor district, it is located in the western inland and one of the most imbalanced areas with regional development in China. After studied the lit-eratures, we found the academia has not discussed the country economy from the perspective of industrial structure in Yunnan Province. So this article takes the shift share analysis and Industry decomposition of the Gi-ni coefficient methods, based on the data of statistical yearbook, to analyze the evolution of industrial structure effecting county economic difference in Yunnan Province. The results show that: the economic disparities of counties affected by the deviation of industrial structure and competition greatly, the eastern counties of the in-dustrial structure have a significant advantage, but the relative competitive advantage is weak, the western and southern counties have more competitive advantage, but less structural disadvantages than the eastern counties. In recent years, the eastern counties are dominant in the industrial structure, competitiveness, and the differ-ence between the western and southern county are widened;the results from the decomposition of the Gini co-efficient of industry indicate that the secondary industry is the leading factor causing the county economy dif-ference. In addition, the tertiary industry contributes to increase county economic difference and its impacts on
