  9. Mechanical analysis of Chen chaotic system

    International Nuclear Information System (INIS)

    Liang, Xiyin; Qi, Guoyuan

    2017-01-01

    The Chen chaotic system is transformed into Kolmogorov type system, which is decomposed into four types of torques: inertial torque, internal torque, dissipation and external torque. By the combinations of different torques, five cases are studied to discover key factors of chaos generation and the physical meaning. The conversion among Hamiltonian energy, kinetic energy and potential energy is investigated in these five cases. The relationship between the energies and the parameters is studied. It concludes that the combination of these four types of torques is necessary conditions to produce chaos, and any combination of three types of torques cannot produce chaos in Chen system.

  11. Titanisierung von Implantatoberflächen

    Science.gov (United States)

    Zimmermann, Hanngörg; Heinlein, Markus; Guldner, Norbert W.

    Titan gilt seit Jahrzehnten als einer der wichtigsten Implantatwerkstoffe in der Medizin. Neben den guten mechanischen Eigenschaften (Leichtigkeit, hohe Festigkeit etc.), besitzen Titanimplantate vor allem eine hervorragende Körperverträglichkeit, so dass die Implantate optimal in den humanen Organismus integriert werden [1]. Ist jedoch aufgrund der Anforderungen an das Implantat eine hohe Flexibilität und/ oder Elastizität gefragt, so scheidet der Werkstoff Titan aufgrund seiner spröden und unflexiblen Materialeigenschaften aus. Die Folge ist der Einsatz von Implantatmaterialien, sowohl künstlichen als auch biologischen Ursprungs, welche nicht selten eine unzureichende Biokompatibilität aufweisen und somit zu Fremdköper- und immunologischen Reaktionen und Einkapselung des Implantates führen können. Die Erhöhung der Körperverträglichkeit, eine Adaption an das biologische Umfeld und eine hohe Biokompatibilität sind demzufolge die wichtigsten Eigenschaften bei der bedarfsgerechten Herstellung von Implantaten und Implantatoberflächen. Zur Gestaltung von innovativen, biokompatiblen Oberflächen stehen unterschiedliche technische Lösungsansätze zur Verfügung. Zum einen besteht die Möglichkeit, geeignete Oberflächeneigenschaften aus dem Grundmaterial selbst zu optimieren. Dies geschieht unter anderem durch Modifikation der Werkstoffoberflächen in Form von Texturierungen und Oberflächenrauhigkeiten. Zum anderen können die Oberflächeneigenschaften unabhängig von denen des Trägermaterials gestaltet werden. Durch Funktionalisierung der Oberflächen mit geeigneten Beschichtungen oder der Zugabe von Medikamenten (Drug Eluting) werden die Kunststoffimplantate dahingehend verändert, dass eine Steigerung der Körperakzeptanz erreicht wird. Die Titanbeschichtung von Implantatoberflächen kombiniert die positiven Materialeigenschaften von Titan und Polymer.

  12. Chaos control of Chen chaotic dynamical system

    International Nuclear Information System (INIS)

    Yassen, M.T.

    2003-01-01

    This paper is devoted to study the problem of controlling chaos in Chen chaotic dynamical system. Two different methods of control, feedback and nonfeedback methods are used to suppress chaos to unstable equilibria or unstable periodic orbits (UPO). The Lyapunov direct method and Routh-Hurwitz criteria are used to study the conditions of the asymptotic stability of the steady states of the controlled system. Numerical simulations are presented to show these results

  13. Impulsive synchronization of Chen's hyperchaotic system

    Haeri, Mohammad; Dehghani, Mahsa

    2006-01-01

    In this Letter the impulsive synchronization of the Chen's hyperchaotic systems is discussed. Some new and sufficient conditions on varying impulsive distance are established in order to guarantee the synchronizabillity of the systems using the synchronization method. In particular, some simple conditions are derived in synchronizing the systems by equal impulsive distances. Two illustrative examples are provided to show the feasibility and the effectiveness of the proposed method. The boundaries of the stable regions are also estimated

    Noorani, M.S.M.; Hashim, I.; Ahmad, R.; Bakar, S.A.; Ismail, E.S.; Zakaria, A.M.

    2007-01-01

    In this paper, the Adomian decomposition method (ADM) is applied to the Chen system which is a three-dimensional system of ODEs with quadratic nonlinearities. The ADM yields an analytical solution in terms of a rapidly convergent infinite power series with easily computable terms. Comparisons between the decomposition solutions and the classical fourth-order Runge-Kutta (RK4) numerical solutions are made. In particular we look at the accuracy of the ADM as the Chen system changes from a non-chaotic system to a chaotic one. To highlight some computational difficulties due to a high Lyapunov exponent, a comparison with the Lorenz system is given

  4. The age grading and the Chen-Ruan cup product

    DEFF Research Database (Denmark)

    2010-01-01

    We prove that the obstruction bundle used to define the cup-product in Chen-Ruan cohomology is determined by the so-called `age grading' or `degree-shifting numbers'. Indeed, the obstruction bundle can be directly computed using the age grading. We obtain a Kunneth Theorem for Chen-Ruan cohomology...... as a direct consequence of an elementary property of the age grading, and explain how several other results - including associativity of the cup-product - can be proved in a similar way....

    1986-01-01

    A few specialists have been finding time to think beyond the LEP electron- positron Collider now being built at CERN and the SSC Superconducting Super Collider proposed for the US to the physics needs and accelerator possibilities of the future. Despite the modest effort, a lot of progress has been made in sorting the wheat from the chaff amongst proposed accelerator schemes and in defining crucial features of future machines. Some of this thinking came together at a seminar on 'New Techniques for Future Accelerators' held in Erice, Sicily, from 12-17 May

  12. Alternative implementation of the chaotic Chen-Lee system

    International Nuclear Information System (INIS)

    Sheu, L.-J.; Tam, L.-M.; Chen, H.-K.; Lao, S.-K.

    2009-01-01

    The chaotic Chen-Lee system was developed with a formalism based on the Euler equations for the motion of a rigid body. It was proved that this system is the governing set of equations for gyro motion with feedback control. Recently, studies were conducted to explore the dynamic behavior of this system, including fractional order behavior, the generation of hyperchaos and perturbation analysis, control and anti-control of chaos, synchronization, etc. In this study, we further explore (1) the stability of the equilibrium points and (2) the implementation of an electronic circuit using the Chen-Lee system. It is shown that not only is this system related to gyro motion but can also be applied to electronic circuits for encryption purposes.

  14. Eric Davidson and deep time.

    Science.gov (United States)

    Erwin, Douglas H

    2017-10-13

    Eric Davidson had a deep and abiding interest in the role developmental mechanisms played in generating evolutionary patterns documented in deep time, from the origin of the euechinoids to the processes responsible for the morphological architectures of major animal clades. Although not an evolutionary biologist, Davidson's interests long preceded the current excitement over comparative evolutionary developmental biology. Here I discuss three aspects at the intersection between his research and evolutionary patterns in deep time: First, understanding the mechanisms of body plan formation, particularly those associated with the early diversification of major metazoan clades. Second, a critique of early claims about ancestral metazoans based on the discoveries of highly conserved genes across bilaterian animals. Third, Davidson's own involvement in paleontology through a collaborative study of the fossil embryos from the Ediacaran Doushantuo Formation in south China.

    Professor CHEN Xiuhua 's clinical experiences were introduced in the intervention on atopic dermatitis with external therapies of TCM acupuncture. On the basis of the theory as cultivating the earth and clearing the heart from professor CHEN Dacan and in terms of the disease stages and skin lesion characteristics, as well as in consideration of syndrome differen-tiation, the acupoints for strengthening the spleen and clearing heart fire are selected, such as Zhongwan (CV 12), Daheng (SP 15), Shuifen (CV 9), Tianshu (ST 25), Neiguan (PC 6) and Quchi (LI 11). For the repair of skin lesion, the integration of Chinese and western medicine is used, with the internal application and external use of Chinese herbal medicines involved. The topical ointments are selected rationally. The self-blood therapy is used with acupuncture, bleeding therapy and acupoint injection applied in combination on the basis of the theory of TCM zangfu organs and modern immunological mechanism, which stimulates the nonspecific immune response in the body and strengthens acupoint stimulus effects. Medical thread therapy of Guangxi Zhuang medicine is used in moxibustion for skin damage, which effectively stops itching and promotes wound healing and skin repair.

  10. Sociology in Times of Crisis: Chen Da, National Salvation and the Indigenization of Knowledge

    Directory of Open Access Journals (Sweden)

    Ana Maria Candela

    2015-08-01

    Full Text Available Chen Da was one of the foremost sociologists of China from the 1920s to the 1940s. His intellectual habitus took shape from the long crisis that defined Chinese intellectual life from the mid-19th to mid-20th centuries, a period of continuous imperial assault on Chinese sovereignty. As China integrated into the capitalist world-system, neo-Confucian structures of knowledge came into question. Intellectuals took up sociology to guide China’s transition from an empire to a nation-state. Through his studies on labor, migration, and population, Chen Da contributed to the institutionalization of sociology in China. Chen sought to craft a theory of Chinese development that followed universal trajectories of progress but was also attuned to the complexity of Chinese society on the ground. Through his efforts to indigenize sociology, Chen developed a non-Marxist historical materialism, a deterritorialized and pluralistic conceptualization of China as a nation, and a theory of eugenic transformation centered on the concept of “mode of living.” The questions which Chen Da confronted are emblematic of the predicament faced by Chinese social scientists today, who again struggle with the dynamics of a deterritorialzied “Greater China,” rising social fragmentation, and refigured eugenic discourses and policies that aim to craft the Chinese people into ideal national subjects fit for post-socialist development.

  11. Hopf bifurcation analysis of Chen circuit with direct time delay feedback

    International Nuclear Information System (INIS)

    Hai-Peng, Ren; Wen-Chao, Li; Ding, Liu

    2010-01-01

    Direct time delay feedback can make non-chaotic Chen circuit chaotic. The chaotic Chen circuit with direct time delay feedback possesses rich and complex dynamical behaviours. To reach a deep and clear understanding of the dynamics of such circuits described by delay differential equations, Hopf bifurcation in the circuit is analysed using the Hopf bifurcation theory and the central manifold theorem in this paper. Bifurcation points and bifurcation directions are derived in detail, which prove to be consistent with the previous bifurcation diagram. Numerical simulations and experimental results are given to verify the theoretical analysis. Hopf bifurcation analysis can explain and predict the periodical orbit (oscillation) in Chen circuit with direct time delay feedback. Bifurcation boundaries are derived using the Hopf bifurcation analysis, which will be helpful for determining the parameters in the stabilisation of the originally chaotic circuit

    This study demonstrates that synchronization and anti-synchronization can coexist in Chen-Lee chaotic systems by direct linear coupling. Based on Lyapunov's direct method, a linear controller was designed to assure that two different types of synchronization can simultaneously be achieved. Further, the hybrid projective synchronization of Chen-Lee chaotic systems was studied using a nonlinear control scheme. The nonlinear controller was designed according to the Lyapunov stability theory to guarantee the hybrid projective synchronization, including synchronization, anti-synchronization, and projective synchronization. Finally, numerical examples are presented in order to illustrate the proposed synchronization approach.

  15. TEST OF THE CHEN-ROLL-ROSS MACROECONOMIC FACTOR MODEL: EVIDENCE FROM CROATIAN STOCK MARKET

    2015-12-01

    Full Text Available This paper empirically examines the well-known Chen-Roll-Ross model on the Croatian stock market. Modifications of definitions of the Chen-Roll-Ross model variables showed as necessary because of doubtful availability and quality of input data needed. Namely, some macroeconomic and market variables are not available in the originally defined form or do not exist. In that sense this paper gives some alternative definitions for some model variables. Also, in order to improve statistical analysis, in this paper we have modified Fama-MacBeth technique in the way that second-pass regression was substituted with panel regression analysis. Based on the two-pass regression analysis of returns of 34 Croatian stocks on 4 macroeconomic variables during the seven-and-half-year observation period the following conclusion is made. In contrast to the results of Chen, Roll and Ross (1986 for the U.S. stock market, their model is not successful when describing a risk-return relation of Croatian stocks. Nevertheless, one observed version of the Chen-RollRoss model showed certain statistical significance. Namely, two risk factors in that version of the model were statistically significant: default premium, measured as risk premium for the corporate short-term bank loan financing, and term structure premium, measured on short-run basis.

  1. Self-Representation and Cultural Expectations: Yogi Chen and Religious Practices of Life-Writing

    Full Text Available Explores the differences in self-representation as found in the autobiographical writings of Yogi Chen, Billy Graham, and the Dalai Lama. While the latter two are widely recognized in American popular religious culture, the former is virtually invisible outside the immigrant Chinese American community. This invisibility is consistent with fact that the religious praxes of immigrant communities remain largely under-studied. However, one additional factor appears to be the mismatch between the expectations of the dominant religious culture and the immigrant culture in terms of the ways in which religious leaders represent themselves. Both Billy Graham and the Dalai Lama present themselves in very humble terms, consistent with the expectations of the Pietist background to American popular religion. Yogi Chen on the contrary tends toward a self-aggrandizing style, which although consistent with the competitive nature of premodern Tibetan religious culture is not congruent with the expectations of American popular religion.

    The dynamics of fractional-order systems have attracted a great deal of attention in recent years. In this paper, the effects of parameter changes on the dynamics of the fractional-order Chen-Lee system were studied numerically. The parameter ranges used were relatively broad. The order used for the system was fixed at 2.7 (q{sub 1} = q{sub 2} = q{sub 3} = 0.9). The system displays rich dynamic behaviors, such as a fixed point, periodic motion (including period-3 motion), chaotic motion, and transient chaos. The chaotic motion identified was validated by the confirmation of a positive Lyapunov exponent. Period-doubling routes to chaos in the fractional-order Chen-Lee system were also found.

    The epitome of this paper centers on the application of the differential transformation method (DTM) the renowned Chen system which is described as a three-dimensional system of ODEs with quadratic nonlinearities. Numerical comparisons are made between the DTM and the classical fourth-order Runge-Kutta method (RK4). Our work showcases the precision of the DTM as the Chen system transforms from a non-chaotic system to a chaotic one. Since the Lyapunov exponent for this system is much higher compared to other chaotic systems, we shall highlight the difficulties of the simulations with respect to its accuracy. We wrap up our investigations to reveal that this direct symbolic-numeric scheme is effective and accurate.

  7. Tensioned Fabric Structures with Surface in the Form of Chen-Gackstatter

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Form-finding has to be carried out for tensioned fabric structure in order to determine the initial equilibrium shape under prescribed support condition and prestress pattern. Tensioned fabric structures are normally designed to be in the form of equal tensioned surface. Tensioned fabric structure is highly suited to be used for realizing surfaces of complex or new forms. However, research study on a new form as a tensioned fabric structure has not attracted much attention. Another source of inspiration minimal surface which could be adopted as form for tensioned fabric structure is very crucial. The aim of this study is to propose initial equilibrium shape of tensioned fabric structures in the form of Chen-Gackstatter. Computational form-finding using nonlinear analysis method is used to determine the Chen-Gackstatter form of uniformly stressed surfaces. A tensioned fabric structure must curve equally in opposite directions to give the resulting surface a three dimensional stability. In an anticlastic doubly curved surface, the sum of all positive and all negative curvatures is zero. This study provides an alternative choice for structural designer to consider the Chen-Gackstatter applied in tensioned fabric structures. The results on factors affecting initial equilibrium shape can serve as a reference for proper selection of surface parameter for achieving a structurally viable surface.

  8. Ronald Malt or Chen Zhongwei: Who performed the first surgical replantation?

    Science.gov (United States)

    Fan, Ka-Wai

    2018-01-01

    This article discusses the contributions of the two pioneers of the surgical procedure of replantation-Ronald Malt in the US and Chen Zhongwei in China. Ronald Malt performed the reattachment surgery on a boy who had an accident in 1962, but he published his case report two years later in 1964. Chen Zhongwei performed a similar surgery on a worker who cut off his forearm in 1963, but he published his case report the same year. There is some debate about which one of these reputed surgeons should be given credit for being the first one to perform this breakthrough surgery, because although Malt was the first to perform the procedure, Zhongwei was the first to report it. To shed light on this controversy, criteria for scientific priority suggested by Ronald Vale and Anthony Hyman were applied. Although the criteria mainly favored Zhongwei as the pioneer of this procedure, he did not entirely fulfill one of the criteria. Therefore, the article could not present a definitive answer to the question, and it concludes by pointing out the highly commendable achievements and contributions of both Ronald Malt and Chen Zhongwei.

  9. Time budgets of Snow Geese Chen caerulescens and Ross's Geese Chen rossii in mixed flocks: Implications of body size, ambient temperature and family associations

    2009-01-01

    Body size affects foraging and forage intake rates directly via energetic processes and indirectly through interactions with social status and social behaviour. Ambient temperature has a relatively greater effect on the energetics of smaller species, which also generally are more vulnerable to predator attacks than are larger species. We examined variability in an index of intake rates and an index of alertness in Lesser Snow Geese Chen caerulescens caerulescens and Ross's Geese Chen rossii wintering in southwest Louisiana. Specifically we examined variation in these response variables that could be attributed to species, age, family size and ambient temperature. We hypothesized that the smaller Ross's Geese would spend relatively more time feeding, exhibit relatively higher peck rates, spend more time alert or raise their heads up from feeding more frequently, and would respond to declining temperatures by increasing their proportion of time spent feeding. As predicted, we found that Ross's Geese spent more time feeding than did Snow Geese and had slightly higher peck rates than Snow Geese in one of two winters. Ross's Geese spent more time alert than did Snow Geese in one winter, but alert rates differed by family size, independent of species, in contrast to our prediction. In one winter, time spent foraging and walking was inversely related to average daily temperature, but both varied independently of species. Effects of age and family size on time budgets were generally independent of species and in accordance with previous studies. We conclude that body size is a key variable influencing time spent feeding in Ross's Geese, which may require a high time spent feeding at the expense of other activities. ?? 2008 The Authors.

    A system with more than one positive Lyapunov exponent can be classified as a hyperchaotic system. In this study, a sinusoidal perturbation was designed for generating hyperchaos from the Chen-Lee chaotic system. The hyperchaos was identified by the existence of two positive Lyapunov exponents and bifurcation diagrams. The system is hyperchaotic in several different regions of the parameters c, {epsilon}, and {omega}. It was found that this method not only can enhance or suppress chaotic behavior, but also induces chaos in non-chaotic parameter ranges. In addition, two interesting dynamical behaviors, Hopf bifurcation and intermittency, were also found in this study.

    Recently, a novel pseudorandom number generator scheme based on the Chen chaotic system was proposed. In this study, we analyze the security weaknesses of the proposed generator. By applying a brute force attack on a reduced key space, we show that 66% of the generated pseudorandom number sequences can be revealed. Executable C# code is given for the proposed attack. The computational complexity of this attack is O(n), where n is the sequence length. Both mathematical proofs and experimental results are presented to support the proposed attack.

    2010-01-01

    Since the past two decades, the time delay feedback control method has attracted more and more attention in chaos control studies because of its simplicity and efficiency compared with other chaos control schemes. Recently, it has been proposed to suppress low-dimensional chaos with the notch filter feedback control method, which can be implemented in a laser system. In this work, we have analytically determined the controllable conditions for notch filter feedback controlling of Chen chaotic system in terms of the Hopf bifurcation theory. The conditions for notch filter feedback controlled Chen chaoitc system having a stable limit cycle solution are given. Meanwhile, we also analysed the Hopf bifurcation direction, which is very important for parameter settings in notch filter feedback control applications. Finally, we apply the notch filter feedback control methods to the electronic circuit experiments and numerical simulations based on the theoretical analysis. The controlling results of notch filter feedback control method well prove the feasibility and reliability of the theoretical analysis. (general)

    2016-07-01

    Chen Jingrun (1933-1996), perhaps the most prodigious mathematician of his time, focused on the field of analytical number theory. His work on Waring's problem, Legendre's conjecture, and Goldbach's conjecture led to progress in analytical number theory in the form of "Chen's Theorem," which he published in 1966 and 1973. His early life was ravaged by the Second Sino-Japanese War and the Chinese Cultural Revolution. On the verge of solving Goldbach's conjecture in 1984, Chen was struck by a bicyclist while also bicycling and suffered severe brain trauma. During his hospitalization, he was also found to have Parkinson's disease. Chen suffered another serious brain concussion after a fall only a few months after recovering from the bicycle crash. With significant deficits, he remained hospitalized for several years without making progress while receiving modern Western medical therapies. In 1988 traditional Chinese medicine experts were called in to assist with his treatment. After a year of acupuncture and oxygen therapy, Chen could control his basic bowel and bladder functions, he could walk slowly, and his swallowing and speech improved. When Chen was unable to produce complex work or finish his final work on Goldbach's conjecture, his mathematical pursuits were taken up vigorously by his dedicated students. He was able to publish Youth Math, a mathematics book that became an inspiration in Chinese education. Although he died in 1996 at the age of 63 after surviving brutal political repression, being deprived of neurological function at the very peak of his genius, and having to be supported by his wife, Chen ironically became a symbol of dedication, perseverance, and motivation to his students and associates, to Chinese youth, to a nation, and to mathematicians and scientists worldwide.

Isso não quer dizer que todos os movimentos revolucionários sejam milenaristas em sentido estrito ou, pior todavia, que respondam a um quiliasmo de tipo primitivo. Isso não impede afirmar que a afinidade entre os dois seja um fato fundamental na história das revoltas camponesas contra a modernização capitalista. Trata-se de uma das hipóteses de investigação mais interessantes esquematizadas em seus trabalhos desta época. Hobs-bawm ilustra seus propósitos com dois estudos de caso apaixonantes: o anarquismo rural na Andaluzia e as ligas camponesas da Sicília, os dois surgidos em fins do século XIX com prolongamentos no XX.Thanks to the problematic of millenarianism, Eric Hobsbawm's historiography incorporates all the richness of socio-cultural subjectivity - the depth of beliefs, feelings and emotions - into his analysis of historical events, which, from this viewpoint, are no longer perceived simply as products of the "objective" interplay of economic or political forces. Although he makes a careful distinction between primitive millenarianisms and modern revolutionary movements, Hobsbawm nevertheless shows their elective affinity between them. This does not mean that all revolutionary movements are millenarian in the strict sense or - which is even worse - that they are connected to a primitive type of chiliasm. All the same, the affinity between them is a basic fact in the history of peasant revolts against capitalist modernization. This

    In this paper, a novel four dimensional hyper-chaotic system is coined based on the Chen system, which contains two quadratic terms and five system parameters. The proposed system can generate a hyper-chaotic attractor in wide parameters regions. By using the center manifold theorem and the local bifurcation theory, a pitchfork bifurcation is demonstrated to arise at the zero equilibrium point. Numerical analysis demonstrates that the hyper-chaotic system can generate complex dynamical behaviors, e.g., a direct transition from quasi-periodic behavior to hyper-chaotic behavior. Finally, an electronic circuit is designed to implement the hyper-chaotic system, the experimental results are consist with the numerical simulations, which verifies the existence of the hyper-chaotic attractor. Due to the complex dynamic behaviors, this new hyper-chaotic system is useful in the secure communication. (general)

    In this paper, we show that the Chen-Nester-Tung (CNT) quasi-local energy with 4D isometric matching references is closely related to the Wang-Yau (WY) quasi-local energy. As a particular example, we compute the second variation of the CNT quasi-local energy for axially symmetric Kerr-like spacetimes with axially symmetric embeddings at the obvious critical point (0 , 0) and find that it is a saddle critical point in most of the cases. Also, as a byproduct, we generalize a previous result about the coincidence of the CNT quasi-local energy and Brown-York mass for axially symmetric Kerr-like spacetimes by Tam and the first author Liu and Tam (2016) to general spacetimes.

    Wang-Chen system with only one stable equilibrium as well as the coexistence of hidden attractors has attracted increasing interest due to its striking features. In this work, the effect of state feedback on Wang-Chen system is investigated by introducing a further state variable. It is worth noting that a new chaotic system without equilibrium is obtained. We believe that the system is an interesting example to illustrate the conversion of hidden attractors with one stable equilibrium to hidden attractors without equilibrium.

    Lakes are important junctions of geospheres. There are many lakes distributed on the Tibetan Plateau (TP). Lake sediment is one of the important media for retrieving the past environmental changes. Because of the uniqueness of environment of the TP, sediment, water and ecological system in lakes has local characteristic inevitably. Modern process research on different lakes will benefit interpreting the proxies more accurately. The development of observation station makes the observation and sampling more convenient. Modern process of lakes can be fulfilled in two ways, spatial or seasonal variation study, with a same aim finding out the dominant factors controlling the variations. Chen Co is a closed lake locating at inland area of southern Tibet. Ranwu Lake is an open lake locating at outflow area of SE Tibet. In this study, I studied the spatial and (or) seasonal variation of lake water and sediment in the two distinct types of lakes to make clear the mechanism of modern process. Particular attention was given to the pattern and degree of influence of rivers supplied by glaciers on lakes. Preliminary conclusions are outlined as follow: (1) In the lakes with glacier melt supplying rivers, the patterns of supply of the rivers to the lake are different. In close lake Chen Co, the influence of glacier melt is mainly reflected in the south lake area. In the open lake Ranwu Lake, the influence is comprehensive and direct. This difference influencing patterns how the lake sediments reflected the glacier melt under the past environmental changes. (2) The supply of Kaluxiong Qu River, supplied mainly by glacier melt, to Chen co has North-South difference: more directly to south lake area, reflecting by lower value of conductivity and pH, finer grain size and west to east transporting trend, greater deposition rate, more allogenic fine sediments, not obvious biological and endogenic deposition there. This enlightens the site selection for lake cores and interpretation of

  18. The impact of systematic landscape conservation planning on ecosystem: Chen Youlan river watershed

    Heraclitus said that "no man ever steps in the same river twice." Everything continues to change. Land use change will keep redefine itself and subject the Earth and humankind to collateral changes. Humankind benefits from ecosystem in many ways. The ecosystem provides people with nutrients, enriches soil with sediment, and sustains all living organisms with water; these benefits are known as ecosystem services. In Taiwan, land use change has impacted ecosystem and biodiversity on various levels. Thus, we took six land use scenarios from 1999 to 2005 in Chen Youlan river watershed as our case study, intending to observe the course of ecosystem and biodiversity changes and the cause of it. Systematic Landscape conservation planning (SLCP) framework can be adopted when designing land use policy to safeguard human interests and ecosystem. This study use SLCP to develop ecosystem services and biodiversity protection strategies. Several strategies were designed by using 1999 to 2005 data as provision to protect the intactness of future ecosystem services and biodiversity. This research explores the potential and possible impacts of different land use protection strategies in the future. It is possible to identify the conservation priority of a certain region by using the Zonation meta-algorithm. This study selects the zonation critical protection area (Joint set of Yushan National Park) as strategy A, B and C. Strategy D takes Yushan National Park as a protected area; unstable hot spots in 1999/03 (Joint set of Yushan National Park) are selected as strategy E. Next, we used Kappa statistical method to find the minimal ecosystem services change and biodiversity hotspots change of the five aforementioned strategies and compared with those from 1999/03. By the Kappa statistical method, we further prioritized the important conservation areas by strategy A, B, C, E in the future. The results can not only serve as management reference for government agencies, but also develop

    In the present paper, the exact solutions of spherically symmetrical Einstein field equations describing wormholes supported by phantom energy that violates the null energy condition from Shan-Chen background fluid are obtained. We have considered the important case of the model parameter ψ ∼ 1, which corresponds to the ''saturation effect'', and this regime corresponds to an effective form of ''asymptotic freedom'' for the fluids, but occurring at cosmological rather than subnuclear scales. Then we investigate the allowed range for the values of the model parameters g and ω when the spacetime metrics describe wormholes and discuss the possible singularities of the solutions, finding that the obtained spacetimes are geodesically complete. Furthermore, we construct two traversable wormholes through matching our obtained interior solutions to the exterior Schwarzschild solutions and analyze the traversabilities of the wormholes. Finally, we consider the case of anisotropic pressure and discover that the transverse pressure also crosses the phantom divide -1 with the growth of the wormhole dimension, and it tends to be the same as the radial pressure with the growth of the wormhole radius.

    The Revised Chen Internet Addiction Scale (CIAS-R) was developed to assess Internet addiction in Chinese populations, but its psychometric properties in adolescents have not been examined. This study aimed to evaluate the factor structure and psychometric properties of CIAS-R in Hong Kong Chinese adolescents. 860 Grade 7 to 13 students (38 % boys) completed the CIAS-R, the Young's Internet Addiction Test (IAT), and the Health of the Nation Outcome Scales for Children and Adolescents (HoNOSCA) in a survey. The prevalence of Internet addiction as assessed by CIAS-R was 18 %. High internal consistency and inter-item correlations were reported for the CIAS-R. Results from the confirmatory factor analysis suggested a four-factor structure of Compulsive Use and Withdrawal, Tolerance, Interpersonal and Health-related Problems, and Time Management Problems. Moreover, results of hierarchical multiple regression supported the incremental validity of the CIAS-R to predict mental health outcomes beyond the effects of demographic differences and self-reported time spent online. The CIAS is a reliable and valid measure of internet addiction problems in Hong Kong adolescents. Future study is warranted to validate the cutoffs of the CIAS-R for identification of adolescents with Internet use problems who may have mental health needs.

    2006-09-01

    Full Text Available The past decade has witnessed an unprecedented rise in the global flow of knowledge, nowhere more apparent in the exchange of ideas between China and modern western democracies. Our interest concerns one aspect of this global flow— the translation of Chinese women’s autobiographical writing into English. Taking Chen Ran’s A Private Life (English edition, 2004 as a point of departure, the paper explores issues of translingual practice and cross-cultural exchange. It considers what escapes or is lost in translation as well as the additive potential of the host text. It is sometimes the case that the translation can deliberately make certain ambiguities visible—whether from pragmatic, market-driven motivations or from more complex political, historical and cultural considerations. These negotiations of meaning that occur in the translation process can reverberate on the critical reception of texts in both the ‘guest’ and ‘host’ languages (Liu 1995, with open-ended, incomplete and indeterminate effects. The paper examines the effects of the omission of a brief parenthetical section of three paragraphs from one chapter of the Chinese edition of A Private Life. Yet, even that small emendation changes the original text as a cultural object and alters potential modes of its reception. In this case, the translation results in a loss of ambiguity, irony, philosophic and rhetorical sophistication while also offering additive potentials that enhance the generation of new meanings in the translingual exchange, here with reference Tiananmen and contemporary feminism in China. The translation process provides new channels for readers, writers and theorists to dialogue and communicate across gaps of difference, despite inhibiting factors like the imposition of local restraints, the universalising pressures of western modernity, and asymmetrical relations of power between guest and host language contexts.

  15. Eric Hermelin and mystical hermeneutics: interpretation beyond itself

    Directory of Open Access Journals (Sweden)

    Tina Hamrin

    1999-01-01

    Full Text Available Eric Hermelin (1860-1944 translated more than 10.000 pages Persian Sufi poetry, German texts by Jakob Böhme and Latin texts by Emmanuel Swedenborg. In the translation process Hermelin shaped his strategies and perceptions in ways which served their patterns of desire, and what they constructed reflected and served their own unique identity. Added up, the devices which constitute strategies of reading set in motion by the selfs defense of its identity are: Defenses, Expectations, Fantasies, and Transformations. Hermelin's mystical hermeneutics produced not only understanding of texts, but often no less produced an increased awareness, with appropriate hermeneutical sensitivity, of self-perception and self-identity. A self-awareness and a strengthening of an individual and corporate identity as one who has a stake in the texts and that to which they bear witness constitutes an important reader-effect in this case of Sufi poetry. But without any principle of suspicion, in Gadamer's terminology a premature fusion of horizons will take place before Hermelin has listened in openness with respect for the tension between the horizons of the text and the horizon of Hermelin. The textual horizon has col-lapsed into that of Hermelin's narrative biography, and is unable to do more than to speak back his own valnes and desires. Something socio-pragmatical was after all woven into the controversial bon vivant, when he used literary works to replicate himself. At the same time, the texts spoke from beyond the self.

    Full Text Available On April 20, 1999, Eric Harris and Dylan Klebold murdered 12 students and one teacher at Columbine High School in Littleton, Colorado, in what was then the deadliest school shooting in American history. Despite causing a national panic and serving as a flash point for larger narratives on bullying, gun control, and media violence, both boys have gained active online fans. These fandoms dedicated to the Columbine shooters are widely referred to as dark examples of Internet communities, while the fans are also frequently denigrated as unstable and violent outcasts. Such dark online fandoms are yet to permeate mainstream culture or to challenge the preexisting perception of these communities as breeding grounds for the next wave of school shooters. While studies have covered the types of fans and their myriad interests, the field remains focused on more conventional examples of fan communities. In an effort to challenge and expand the object of focus when we study fandom, this qualitative study examines Columbine fans and their activity in order to understand the dominant motives they appear to have for engaging with and around such controversial figures and then concludes by exploring how this community might help us reflect more broadly on our concept of fandom. Redeeming these fans as part of diverse and complex communities of social relevance can demonstrate how even a dark fandom such as that of these Columbine shooters provides valuable cultural insights and benefits the field of fan studies.

    2005-01-01

    Full Text Available In 1996 typhoon Herb struck the central Taiwan area, causing severe debris flow in many subwatersheds of the Chen-You-Lan river watershed. More severe cases of debris flow occurred following Chi-Chi earthquake, 1999. In order to identify the potentially affected area and its severity, the ability to simulate the flow route of debris is desirable. In this research numerical simulation of debris flow deposition process had been carried out using FLO-2D adopting Chui-Sue river watershed as the study area. Sensitivity study of parameters used in the numerical model was conducted and adjustments were made empirically. The micro-geomorphic database of Chui-Sue river watershed was generated and analyzed to understand the terrain variations caused by the debris flow. Based on the micro-geomorphic analysis, the debris deposition in the Chui-Sue river watershed in the downstream area, and the position and volume of debris deposition were determined. The simulated results appeared to agree fairly well with the results of micro-geomorphic study of the area when not affected by other inflow rivers, and the trends of debris distribution in the study area appeared to be fairly consistent.

  16. Satellite-derived land covers for runoff estimation using SCS-CN method in Chen-You-Lan Watershed, Taiwan

    2017-04-01

    The Soil Conservation Service Curve Number (SCS-CN) method, which was originally developed by the USDA Natural Resources Conservation Service, is widely used to estimate direct runoff volume from rainfall. The runoff Curve Number (CN) parameter is based on the hydrologic soil group and land use factors. In Taiwan, the national land use maps were interpreted from aerial photos in 1995 and 2008. Rapid updating of post-disaster land use map is limited due to the high cost of production, so the classification of satellite images is the alternative method to obtain the land use map. In this study, Normalized Difference Vegetation Index (NDVI) in Chen-You-Lan Watershed was derived from dry and wet season of Landsat imageries during 2003 - 2008. Land covers were interpreted from mean value and standard deviation of NDVI and were categorized into 4 groups i.e. forest, grassland, agriculture and bare land. Then, the runoff volume of typhoon events during 2005 - 2009 were estimated using SCS-CN method and verified with the measured runoff data. The result showed that the model efficiency coefficient is 90.77%. Therefore, estimating runoff by using the land cover map classified from satellite images is practicable.

    2009-01-01

    Reduced populations of emperor geese (Chen canagica), a Bering Sea endemic, provided the need to assess plasma biochemistry values as indicators of population health. A precursory step to such an investigation was to evaluate patterns of variability in plasma biochemistry values among age, sex, and reproductive period. Plasma from 63 emperor geese was collected on their breeding grounds on the Yukon-Kuskokwim Delta in western Alaska, USA. The geese sampled included 18 incubating adult females captured, in mid June, on their nests by using bow nets, and 30 adults and 15 goslings captured in corral traps in late July and early August, when the adults were molting their wing feathers and the goslings were 5-6 weeks old. Plasma was evaluated for 15 biochemical parameters, by comparing results among age, sex, and sampling period (incubation versus wing-feather molt). Ten of the 15 biochemical parameters assayed differed among adults during incubation, the adults during molt, and the goslings at molt, whereas sex differences were noted in few parameters.

  18. A variational numerical method based on finite elements for the nonlinear solution characteristics of the periodically forced Chen system

    2017-09-01

    Nonlinear dynamical systems and their solutions are very sensitive to initial conditions and therefore need to be approximated carefully. In this article, we present and analyze nonlinear solution characteristics of the periodically forced Chen system with the application of a variational method based on the concept of finite time-elements. Our approach is based on the discretization of physical time space into finite elements where each time-element is mapped to a natural time space. The solution of the system is then determined in natural time space using a set of suitable basis functions. The numerical algorithm is presented and implemented to compute and analyze nonlinear behavior at different time-step sizes. The obtained results show an excellent agreement with the classical RK-4 and RK-5 methods. The accuracy and convergence of the method is shown by comparing numerically computed results with the exact solution for a test problem. The presented method has shown a great potential in dealing with the solutions of nonlinear dynamical systems and thus can be utilized in delineating different features and characteristics of their solutions.

    Full Text Available The aim of this study was to establish the optimal cut-off points of the Chen Internet Addiction Scale (CIAS, to screen for and diagnose Internet addiction among adolescents in the community by using the well- established diagnostic criteria of Internet addiction. This survey of 454 adolescents used screening (57/58 and diagnostic (63/64 cut-off points of the CIAS, a self-reported instrument, based on the results of systematic diagnostic interviews by psychiatrists. The area under the curve of the receiver operating characteristic curve revealed that CIAS has good diagnostic accuracy (89.6%. The screening cut-off point had high sensitivity (85.6% and the diagnostic cut-off point had the highest diagnostic accuracy, classifying 87.6% of participants correctly. Accordingly, the screening point of the CIAS could provide a screening function in two-stage diagnosis, and the diagnostic point could serve as a diagnostic criterion in one-stage massive epidemiologic research.

  20. Ground-state magnetization of the Ising spin glass: A recursive numerical method and Chen-Ma scaling

    2018-03-01

    The ground-state properties of quasi-one-dimensional (Q1D) Ising spin glass are investigated using an exact numerical approach and analytical arguments. A set of coupled recursive equations for the ground-state energy are introduced and solved numerically. For various types of coupling distribution, we obtain accurate results for magnetization, particularly in the presence of a weak external magnetic field. We show that in the weak magnetic field limit, similar to the 1D model, magnetization exhibits a singular power-law behavior with divergent susceptibility. Remarkably, the spectrum of magnetic exponents is markedly different from that of the 1D system even in the case of two coupled chains. The magnetic exponent makes a crossover from being dependent on a distribution function to a constant value independent of distribution. We provide an analytic theory for these observations by extending the Chen-Ma argument to the Q1D case. We derive an analytical formula for the exponent which is in perfect agreement with the numerical results.

    Full Text Available Yin-Chen-Hao-Tang (YCHT is a famous Chinese medicine formula which has long been used in clinical practice for treating various liver diseases, such as liver fibrosis. However, to date, the mechanism for its anti-fibrotic effects remains unclear. In this paper, an ultra-performance liquid chromatography-time-of-flight mass spectrometry (UPLC-TOF-MS-based metabolomic study was performed to characterize dimethylnitrosamine (DMN-induced liver fibrosis in rats and evaluate the therapeutic effects of YCHT. Partial least squares-discriminant analysis (PLS-DA showed that the model group was well separated from the control group, whereas the YCHT-treated group exhibited a tendency to restore to the controls. Seven significantly changed fibrosis-related metabolites, including unsaturated fatty acids and lysophosphatidylcholines (Lyso-PCs, were identified. Moreover, statistical analysis demonstrated that YCHT treatment could reverse the levels of most metabolites close to the normal levels. These results, along with histological and biochemical examinations, indicate that YCHT has anti-fibrotic effects, which may be due to the suppression of oxidative stress and resulting lipid peroxidation involved in hepatic fibrogenesis. This study offers new opportunities to improve our understanding of liver fibrosis and the anti-fibrotic mechanisms of YCHT.

    We studied body mass of prefledging Emperor Geese Chen canagica at three locations across the Yukon-Kuskokwim Delta, Alaska, during 1990-2004 to investigate whether large-scale variation in body mass was related to interspecific competition for food. From 1990 to 2004, densities of Cackling Geese Branta hutchinsii minima more than doubled and were c. 2-5?? greater than densities of Emperor Geese, which were relatively constant over time. Body mass of prefledging Emperor Geese was strongly related (negatively) to interspecific densities of geese (combined density of Cackling and Emperor Geese) and positively related to measures of food availability (grazing lawn extent and net above-ground primary productivity (NAPP)). Grazing by geese resulted in consumption of ??? 90% of the NAPP that occurred in grazing lawns during the brood-rearing period, suggesting that density-dependent interspecific competition was from exploitation of common food resources. Efforts to increase the population size of Emperor Geese would benefit from considering competitive interactions among goose species and with forage plants. ?? 2008 The Authors.

    Pseudomonas aeruginosa is a major cause of nosocomial infection in children and adults, resulting in significant morbidity and mortality due to its ability to acquire drug resistance. The ability of P. aeruginosa in the environment to cause infection in individuals has been reported previously; henceforth, surveillance of the emergence and transmission of P. aeruginosa strains among patients is important for infection control in a clinical setup. Various gene-typing methods have been used for epidemiological typing of P. aeruginosa isolates for the purpose of surveillance. In this work, the suitability and comparability of two typing methods, enterobacterial repetitive intergenic consensus (ERIC)-PCR and random amplification of polymorphic DNA (RAPD)-PCR fingerprinting, were studied to characterize P. aeruginosa strains isolated from clinical and environmental sources. Forty-four clinical and environmental bacterial isolates of P. aeruginosa were collected between October 2015 and January 2016. DNA extraction, ERIC-PCR and RAPD-PCR, agarose gel electrophoresis, and phylogenetic analyses were carried using the unweighted pair-group method with mean. RAPD typing revealed less clonality among clinical isolates, whereas the ERIC method showed greater similarity in comparison with RAPD. Environmental isolates, however, showed greater similarity using RAPD compared with ERIC typing. With only a few exceptions, most clinical isolates were distinct from environmental isolates, irrespective of the typing method. In conclusion, both the RAPD and ERIC typing methods proved to be good tools in understanding clonal diversity. The results also suggest that there is no relationship between clinical and environmental isolates. The absence of clonality among the clinical isolates may indicate that most P. aeruginosa infection cases could be endemic and not epidemic and that endemic infections may be due to nonclonal strains of P. aeruginosa.

  6. Variation in foraging behavior and body mass in broods of Emperor Geese (Chen canagica): Evidence for interspecific density dependence

    Science.gov (United States)

    Schmutz, J.A.; Laing, K.K.

    2002-01-01

    Broods of geese spend time feeding according to availability and quality of food plants, subject to inherent foraging and digestive constraints. We studied behavioral patterns of broods of Emperor Geese (Chen canagica) on the Yukon–Kuskokwim Delta, Alaska, and examined how feeding and alert behavior varied in relation to habitat and goose density. During 1994–1996, time spent feeding by Emperor Goose goslings and adult females was positively related to multispecies goose densities near observation blinds, and not to just Emperor Goose density. Similarly, body mass of Emperor Goose goslings was more strongly related (negatively) to multispecies goose densities than intraspecific densities. A grazing experiment in 1995 indicated that most above ground primary production by Carex subspathacea, a preferred food plant, was consumed by grazing geese. Those results demonstrate that interspecific competition for food occurred, with greatest support for goslings whose behavioral repertoire is limited primarily to feeding, digesting, and resting. Although the more abundant Cackling Canada Geese (Branta canadensis minima) differed from Emperor Geese in their preferred use of habitats during brooding rearing (Schmutz 2001), the two species occurred in equal abundance in habitats preferred by Emperor Goose broods. Thus, Cackling Canada Geese were a numerically significant competitor with Emperor Geese. Comparing these results to an earlier study, time spent feeding by goslings, adult females, and adult males were greater during 1993–1996 than during 1985–1986. During the interval between those studies, densities of Cackling Canada Geese increased two to three times whereas Emperor Goose numbers remained approximately stable, which implies that interspecific competition affected foraging behavior over a long time period. These density-dependent changes in foraging behavior and body mass indicate that interspecific competition affects nutrient acquisition and gosling

    EPOS - the European Plate Observing System - is the ESFRI infrastructure serving the need of the solid Earth science community at large. The EPOS mission is to create a single sustainable, and distributed infrastructure that integrates the diverse European Research Infrastructures for solid Earth science under a common framework. Thematic Core Services (TCS) and Integrated Core Services (Central Hub, ICS-C and Distributed, ICS-D) are key elements, together with NRIs (National Research Infrastructures), in the EPOS architecture. Following the preparatory phase, EPOS has initiated formal steps to adopt an ERIC legal framework (European Research Infrastructure Consortium). The statutory seat of EPOS will be in Rome, Italy, while the ICS-C will be jointly operated by France, UK and Denmark. The TCS planned so far cover: seismology, near-fault observatories, GNSS data and products, volcano observations, satellite data, geomagnetic observations, anthropogenic hazards, geological information modelling, multiscale laboratories and geo-energy test beds for low carbon energy. In the ERIC process, EPOS and all its services must achieve sustainability from a legal, governance, financial, and technical point of view, as well as full harmonization with national infrastructure roadmaps. As EPOS is a distributed infrastructure, the TCSs have to be linked to the future EPOS ERIC from legal and governance perspectives. For this purpose the TCSs have started to organize themselves as consortia and negotiate agreements to define the roles of the different actors in the consortium as well as their commitment to contribute to the EPOS activities. The link to the EPOS ERIC shall be made by service agreements of dedicated Service Providers. A common EPOS data policy has also been developed, based on the general principles of Open Access and paying careful attention to licensing issues, quality control, and intellectual property rights, which shall apply to the data, data products

    The Enterobacterial repetitive intergenic consensus (ERIC) marker was used to analyze the genetic variability of Mycosphaerella fijiensis, the causative agent of Black Sigatoka disease in banana plants. A total of 123 isolates were used, which were divided into populations based on their original hosts and collection sites in Brazil. A total of 9 loci were amplified, 77.8% of which were found to be polymorphic. The genetic diversity found in the population was 0.20. Analysis of molecular variance (AMOVA) demonstrated that the highest level of genetic variation is within populations. Cluster analysis revealed three main groups in Brazil, with no correlation between geographic and genetic distance.

  17. Balancing Biography and Institutional History: Eric Worrell’s Australian Reptile Park

    Directory of Open Access Journals (Sweden)

    2009-11-01

    Full Text Available When a young naturalist opened his new wildlife park at Wyoming on the NSW Central Coast in the late 1950s, he gave it his own name: Eric Worrell’s Australian Reptile Park. Through the park, Worrell made a significant contribution to environmental education, the development of knowledge of captive animal care and display and the provision of antivenoms for the bites of a range of dangerous creatures. More than this, it was the geographic and emotional centre of Worrell’s world: the fulfilment of a childhood dream, a home for his family and a site for forming new personal and professional relationships. In preparation for the jubilee of the park, its history is being written by two academics from the University of Newcastle. An attractive means of creating the necessary narrative structure and human interest to ensure the wide appeal of this history is to follow Worrell’s lead and place his life at the centre of this institutional history. This is the direction suggested by the written sources on the park and it is accentuated by many of our oral informants who organise their memories of the park around Worrell. To what extent can an institutional history be a biography of the person at the heart of that institution? Is it possible to disentangle the life from the institution? This article offers some preliminary answers to these questions through a case study of the writing of a history of Eric Worrell’s Australian Reptile Park.

    Escherichia coli (E. coli) is the most common cause of urinary infections in hospitals. The aim of this study was to evaluate the ERIC-PCR method for molecular typing of uropathogenic E. coli strains isolated from hospitalized patients. In a cross sectional study, 98 E. coli samples were collected from urine samples taken from patients admitted to Baqiyatallah Hospital from June 2014 to January 2015. The disk agar diffusion method was used to determine antibiotic sensitivity. DNA proliferation based on repetitive intergenic consensus was used to classify the E. coli strains. The products of proliferation were electrophoresed on 1.5% agarose gel, and their dendrograms were drawn. The data were analyzed by online Insillico software. The method used in this research proliferated numerous bands (4-17 bands), ranging from 100 to 3000 base pairs. The detected strains were classified into six clusters (E1-E6) with 70% similarity between them. In this study, uropathogenic E. coli strains belonged to different genotypic clusters. It was found that ERIC-PCR had good differentiation power for molecular typing of uropathogenic E. coli strains isolated from the patients in the study.

    We assessed the genomic diversity and genomic relationship of 28 Astragalus glycyphyllos symbionts by three methodologies based on PCR reaction, i.e., RAPD, ERIC-PCR, and AFLP. The AFLP method with one PstI restriction enzyme and selective PstI-GC primer pair had a comparable discriminatory power as ERIC-PCR one and these fingerprinting techniques distinguished among the studied 28 A. glycyphyllos symbionts 18 and 17 genomotypes, respectively. RAPD method was less discriminatory in the genomotyping of rhizobia analyzed and it efficiently resolved nine genomotypes. The cluster analysis of RAPD, ERIC-PCR, and AFLP profiles resulted in a generally similar grouping of the test strains on generated dendrograms supporting a great potential of these DNA fingerprinting techniques for study of genomic polymorphism and evolutionary relationship of A. glycyphyllos nodulators. The RAPD, ERIC-PCR, and AFLP pattern similarity coefficients between A. glycyphyllos symbionts studied was in the ranges 8-100, 18-100, and 23-100%, respectively.

    Three species of trichostrongylid nematodes were removed from the gizzards of 25 lesser snow geese, Chen caerulescens caerulescens, collected at Winisk, Ont. A 100% prevalence of infection was noted in the sampled population with each bird harboring two or more of the following species: Epomidiostomum crami (prevalence, 92%; mean intensity, 18.7 ± 13.3), Amidostomum anseris (prevalence, 84%; mean intensity, 9.6 ± 9.8), and Amidostomum spatulatum (prevalence, 84%; mean intensity, 11.2 ± 9.8). When large burdens (>30) of both A. anseris and A. spatulatum were present in the mucosal lining of the gizzard, progressive degeneration of the epithilium and koilin linings was noted in 16% of the geese examined. Severe necrotic granulomata observed in the gizzard muscle of 36% of the geese were associated with sizable burdens (>25) of E. crami which were found burrowed in the gizzard muscle.

    Yin-Chen-Hao-Tang (YCHT), a commonly used as a traditional chinese medicine for liver disease. Several studies indicated that YCHT may improving hepatic triglyceride metabolism and anti-apoptotic response as well as decreasing oxidative stress .However, little is known about the role of YCHT in chlorpromazine (CPZ) -induced chlolestatic liver injury. Therefore, we aimed to facilitate the understanding of the pathogenesis of cholestatic liver injury and evaluate the effect of Yin-Chen-Hao-Tang (YCHT) on chlorpromazine (CPZ)-induced cholestatic liver injury in rats based on the change of bile acids (BAs) and free fatty acids (FFAs) alone with the biochemical indicators and histological examination. We conducted an experiment on CPZ-induced cholestatic liver injury in Wistar rats with and without YCHT for nine consecutive days. Serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin (ALB), total bilirubin (TBIL), total cholesterol (TC), triglycerides (TG), low density lipoprotein-cholesterol (LDL-C) were measured to evaluate the protective effect of YCHT against chlorpromazine (CPZ)-induced cholestatic liver injury. Histopathology of the liver tissue showed that pathological injuries were relieved after YCHT pretreatment. In addition, ultra-performance lipid chromatography coupled with quadrupole mass spectrometry (UPLC-MS) and gas chromatography coupled with mass spectrometry (GC-MS) was applied to determine the content of bile acids, free fatty acids, respectively. Obtained data showed that YCHT attenuated the effect of CPZ-induced cholestatic liver injury, which was manifested by the serum biochemical parameters and histopathology of the liver tissue. YCHT regulated the lipid levels as indicated by the reversed serum levels of TC, TG, and LDL-C. YCHT also regulated the disorder of BA and FFA metabolism by CPZ induction. Results indicated that YCHT exerted a protective effect on CPZ-induced cholestasis liver injury. The variance of

    Reports an error in "Is Political Behavior a Viable Coping Strategy to Perceived Organizational Politics? Unveiling the Underlying Resource Dynamics" by Shuhua Sun and Huaizhong Chen ( Journal of Applied Psychology , Advanced Online Publication, May 22, 2017, np). In the article, Table 1 contained a formatting error. Correlation coefficient values in the last four cells of column 6 were misplaced with correlation coefficient values in the last four cells of column 7. All versions of this article have been corrected. (The following abstract of the original article appeared in record 2017-22542-001.) We conduct a theory-driven empirical investigation on whether political behavior, as a coping strategy to perceived organizational politics, creates resource trade-offs in moderating the relationship between perceived organizational politics and task performance. Drawing on conservation of resources theory, we hypothesize that political behavior mitigates the adverse effect of perceived organizational politics on task performance via psychological empowerment, yet exacerbates its adverse effect on task performance via emotional exhaustion. Three-wave multisource data from a sample of 222 employees and their 75 supervisors were collected for hypothesis testing. Findings supported our hypotheses. Our study enhances understandings of the complex resource dynamics of using political behavior to cope with perceived organizational politics and highlights the need to move stress-coping research from a focus on the stress-buffering effect of coping on outcomes to a focus on the underlying competing resource dynamics.

  11. Embracing complexity: the post-secular pilgrimage of Eric-Emmanuel Schmitt

    Directory of Open Access Journals (Sweden)

    Ruth Illman

    2010-01-01

    Full Text Available This article deals with the phenomenon of pilgrimage as a personal transformative process; an exploration of spiritual space rather than a journey undertaken to a physical place. The analysis focuses on the life story and authorship of the novelist and playwright Eric-Emmanuel Schmitt (b. 1960. Schmitt began his career as an academic philosopher specialised in enlightenment rationality. A mystical experience in the deserts of Sahara, however, opened his eyes to the spiritual dimensions of reality and encouraged him to redirect his professional strivings from academic writing to fiction. Today, Schmitt has reached a world-wide audience with his plays and novels on interreligious dialogue, especially the series of five short novellas called Le cycle d’Invisible. These narratives all deal with inter-religious encounters in a complex and compassionate way as Schmitt is particularly concerned with preserving the mystery of the situations he describes. The atheist conviction of his previous life has thus given way to an agnostic and mystically inspired world view focusing on diversity, divinity and inexplicability: “I am obsessed with complexity”, as he puts it himself. The presentation is based on ethnographic material, and key themes to be addressed include pilgrimage as a spiritual journey, interreligious encounters and mystical experiences.

    In Spain, data based on large population-based cohorts adequate to provide an accurate prediction of cardiovascular risk have been scarce. Thus, calibration of the EuroSCORE and Framingham scores has been proposed and done for our population. The aim was to develop a native risk prediction score to accurately estimate the individual cardiovascular risk in the Spanish population. Seven Spanish population-based cohorts including middle-aged and elderly participants were assembled. There were 11800 people (6387 women) representing 107915 person-years of follow-up. A total of 1214 cardiovascular events were identified, of which 633 were fatal. Cox regression analyses were conducted to examine the contributions of the different variables to the 10-year total cardiovascular risk. Age was the strongest cardiovascular risk factor. High systolic blood pressure, diabetes mellitus and smoking were strong predictive factors. The contribution of serum total cholesterol was small. Antihypertensive treatment also had a significant impact on cardiovascular risk, greater in men than in women. The model showed a good discriminative power (C-statistic=0.789 in men and C=0.816 in women). Ten-year risk estimations are displayed graphically in risk charts separately for men and women. The ERICE is a new native cardiovascular risk score for the Spanish population derived from the background and contemporaneous risk of several Spanish cohorts. The ERICE score offers the direct and reliable estimation of total cardiovascular risk, taking in consideration the effect of diabetes mellitus and cardiovascular risk factor management. The ERICE score is a practical and useful tool for clinicians to estimate the total individual cardiovascular risk in Spain. Copyright © 2014 Sociedad Española de Cardiología.

    Aim and hypothesis Using a new study design, we investigate whether next-generation mechanical thrombectomy devices improve clinical outcomes in ischemic stroke patients. We hypothesize that this new methodology is superior to intravenous tissue plasminogen activator therapy alone. Methods and design ERic Acute StrokE Recanalization is an investigator-initiated prospective single-arm, multicenter, controlled, open label study to compare the safety and effectiveness of a new recanalization device and distal access catheter in acute ischemic stroke patients with symptoms attributable to acute ischemic stroke and vessel occlusion of the internal cerebral artery or middle cerebral artery. Study outcome The primary effectiveness endpoint is the volume of saved tissue. Volume of saved tissue is defined as difference of the actual infarct volume and the brain volume that is predicted to develop infarction by using an optimized high-level machine learning model that is trained on data from a historical cohort treated with IV tissue plasminogen activator. Sample size estimates Based on own preliminary data, 45 patients fulfilling all inclusion criteria need to complete the study to show an efficacy >38% with a power of 80% and a one-sided alpha error risk of 0.05 (based on a one sample t-test). Discussion ERic Acute StrokE Recanalization is the first prospective study in interventional stroke therapy to use predictive analytics as primary and secondary endpoint. Such trial design cannot replace randomized controlled trials with clinical endpoints. However, ERic Acute StrokE Recanalization could serve as an exemplary trial design for evaluating nonpivotal neurovascular interventions.

    Biological resources (cells, tissues, bodily fluids or biomolecules) are considered essential raw material for the advancement of health-related biotechnology, for research and development in life sciences, and for ultimately improving human health. Stored in local biobanks, access to the human biological samples and related medical data for transnational research is often limited, in particular for the international life science industry. The recently established pan-European Biobanking and BioMolecular resources Research Infrastructure-European Research Infrastructure Consortium (BBMRI-ERIC) aims to improve accessibility and interoperability between academic and industrial parties to benefit personalized medicine, disease prevention to promote development of new diagnostics, devices and medicines. BBMRI-ERIC is developing the concept of Expert Centre as public-private partnerships in the precompetitive, not-for-profit field to provide a new structure to perform research projects that would face difficulties under currently established models of academic-industry collaboration. By definition, Expert Centres are key intermediaries between public and private sectors performing the analysis of biological samples under internationally standardized conditions. This paper presents the rationale behind the Expert Centres and illustrates the novel concept with model examples.

    The heating history of a droplet during its flight can be divided into two phases: (a) the initial phase when evaporation, although it occurs, does not change the heat balance of the droplet much (the case considered in our previous paper and (b) the final phase when the cooling due to evaporation balances the heat flux from the plasma. The later phase is considered in Chen's comment. In our reply, a very straightforward consideration demonstrates that even in the final phase of the droplet flight, the 'rocket' effect can be significant. (reply)

Although the latter three nominal species have been regarded as valid species and N. erostris has not been reported since 1898, examinations of type specimens of the four nominal species revealed that they represent a single species. A lectotype of Scorpaena erostris is herein designated. Neomerinthe erostris is characterized by having a distinct longitudinal ridge on the lateral surface of the maxilla and a strongly rounded dorsal profile of the head.

    Full Text Available In this study, a total of 24 Listeria spp. strains were analyzed. Twenty-two isolates were obtained in San Luis (Argentina from human, animal, and food samples. Two types of strains, Listeria monocytogenes CLIP 22762 and Listeria innocua CLIP 74915, were included as reference strains. All isolates were biochemically identified and characterized by serotyping, phage typing, and amplification of the flaA gene by polymerase chain reaction (PCR. Repetitive intergenic consensus (ERIC sequence-based PCR was used to generate DNA fingerprints. On the basis of ERIC-PCR fingerprints, Listeria spp. strains were divided into three major clusters matching origin of isolation. ERIC-PCR fingerprints of human and animal isolates were different from those of food isolates. In addition, groups I and II included ten L. monocytogenes strains, and only one Listeria seeligeri strain. Group III included nine L. innocua strains and four L. monocytogenes strains. Computer evaluation of ERIC-PCR fingerprints allowed discrimination between the tested serotypes 1/2b, 4b, 6a, and 6b within each major cluster. The index of discrimination calculated was 0.94. This study suggests that the ERIC-PCR technique provides an alternative method for the identification of Listeria species and the discrimination of strains within one species.En este estudio se analizaron 24 cepas de Listeria spp. De ellas, 22 fueron obtenidas en San Luis (Argentina, a partir de muestras humanas, de animales y alimentos.

    Bacterial populations common to healthy human guts may play important roles in human health. A new strategy for discovering genomic sequences as markers for these bacteria was developed using Enterobacterial Repetitive Intergenic Consensus (ERIC)-PCR fingerprinting. Structural features within microbial communities are compared with ERIC-PCR followed by DNA hybridization to identify genomic fragments shared by samples from healthy human individuals. ERIC-PCR profiles of fecal samples from 12 diseased or healthy human and piglet subjects demonstrated stable, unique banding patterns for each individual tested. Sequence homology of DNA fragments in bands of identical size was examined between samples by hybridization under high stringency conditions with DIG-labeled ERIC-PCR products derived from the fecal sample of one healthy child. Comparative analysis of the hybridization profiles with the original agarose fingerprints identified three predominant bands as signatures for populations associated with healthy human guts with sizes of 500, 800 and 1000 bp. Clone library profiling of the three bands produced 17 genome fragments, three of which showed high similarity only with regions of the Bacteroides thetaiotaomicron genome, while the remainder were orphan sequences. Association of these sequences with healthy guts was validated by sequence-selective PCR experiments, which showed that a single fragment was present in all 32 healthy humans and 13 healthy piglets tested. Two fragments were present in the healthy human group and in 18 children with non-infectious diarrhea but not in eight children with infectious diarrhea. Genome fragments identified with this novel strategy may be used as genome-specific markers for dynamic monitoring and sequence-guided isolation of functionally important bacterial populations in complex communities such as human gut microflora.

    Full Text Available In recent years, Salmonella enterica serovar Enteritidis has been a primary cause of human salmonellosis in many countries. The major objective of this study was to investigate genetic diversity among Salmonella Enteritidis strains from different origins (food and human by Enterobacterial Repetitive Intergenic Consensus (ERIC -PCR, as well as to assess their plasmid profiling and antimicrobial resistance. A total of 30 Salmonella Enteritidis isolates, 15 from food samples (chicken, lamb, beef and duck meats and 15 from clinical samples were collected in Tehran. Identification of isolates as Salmonella was confirmed by using conventional standard biochemical and serological tests. Multiplex-PCR was used for serotyping of isolates to identify Salmonella Enteritidis. Antimicrobial susceptibility testing to 16 agents founds drug resistance patterns among Salmonella Enteritidis isolates. No resistance was observed to cephalexin, ceftriaxone, ceftazidime and cefotaxime, ciprofloxacin, imipenem or meropenem, chloramphenicol and gentamicin. The highest resistance (96.7% was observed to nitrofurantoin. Seven plasmid profiles (P1–P7 were detected, and a 68-kb plasmid was found in all isolates. Two different primers; ERIC and (GTG5 were used for genotyping, which each produced four profiles. The majority of clinical and food isolates fell into two separate common types (CTs with a similar percentage of 95% by ERIC-PCR. Using primer (GTG5, 29 isolates incorporated in three CTs with 70% of isolates showing a single banding pattern. Limited genetic diversity among human and food isolates of Salmonella Enteritidis may indicate that contaminated foods were possibly the source of human salmonellosis. These results confirmed that ERIC-PCR genotyping has limited discriminatory power for Salmonella Enteritidis of different origin.

    Full Text Available Feedback is one of the most significant tools on learning, teaching, developing autonomy, self-efficacy and achievement in the educational environment. Its importance is emphasized in articles, dissertations and theses; however, a very little number of them have been published recently. This article intends to verify in what perspective feedback has been examined, in what ways it has been revealed to be effective for students and teachers to reach their goals and identify possible gaps of study that need to be fulfilled in future researches. In order to carry out this investigation, this study examined articles, papers and theses published from 2006 to 2015 about feedback in courses of English as a foreign language (EFL, using ERIC database. Our findings were organized into six categories: corrective feedback in oral interaction; effects of peer feedback; feedback expectancy; teachers’ conceptions of intelligence and their relations in offering feedback; the effect of different types of feedback strategies on written texts; the use of feedback through technology. The results indicate that feedback is a crucial tool in the educational process and it plays a central role in learning a foreign language. Further investigations concerning feedback are suggested.

    The 12th International Conference on Vibrations at Surfaces (VAS 12) took place from 20 26 July 2007 as an event of the International School of Solid State Physics at the Ettore Majorana Foundation and Centre for Scientific Culture, Erice (Italy). The format and special environment of the conference have contributed to its transition from a traditional, medium-size conference into a more effective workshop, with a series of lectures reporting the most recent developments in the field, two poster sessions presenting recent results and even works in progress being discussed. The papers collected in this issue cover the highlights of the conference very thoroughly. Quite a few novel aspects concerning vibrations at surfaces are represented here, for example: new aspects in surface phonon spectroscopy, such as the very recent progress in inelastic x-ray scattering, the first observation of the boson peak in disordered surfaces, progress in the theory of atom scattering inelastic resonances, the action spectroscopy, the study of polycrystalline surfaces with electron energy-loss spectroscopy etc; parallel developments in experimental vibrational studies of adsorbed phases, either inorganic or organic, with those in ab initio theoretical simulations; the theory of enhanced electron--phonon interaction in low dimensions (2D and 1D); the extension from the traditional realm of surface vibrations and spectroscopy to other aspects of surface dynamics, like friction and various nonlinear effects, and to relevant dynamical phenomena occurring at interfaces. Other novelties presented at the conference, but already published in recent issues of the Journal of Physics: Condensed Matter, are also worth mentioning: the spin-echo spectroscopy with 3He allowing for slow-dynamics spectroscopy at very high, unprecedented resolutions (2007 J. Phys.: Cond. Matter 19 300301 and 305010; the first demonstration of dissociative surface trapping of molecules (2007 J. Phys.: Cond. Matter 19

    In nuclear medicine, the term theranostics describes the combination of therapy and diagnostic imaging. In practice, this concept dates back more than 50 years; however, among the most successful examples of theranostics are peptide receptor scintigraphy and peptide receptor radionuclide therapy of neuroendocrine tumors. The development of these modalities through the radiolabeling of somatostatin analogs with various radionuclides has led to a revolution in patient management and established a foundation for expansion of the theranostic principle into other oncology indications. This article provides a review of the evolution and development of the theranostic radionuclide approach to the management of neuroendocrine tumors, as described by the inventor of this technique, Eric P. Krenning, in an interview with Rachel Levine. © 2017 by the Society of Nuclear Medicine and Molecular Imaging.

    Chlorpyrifos is a widely used insecticide in recent years, and it will produce adverse effects on soil when applied on crops or mixed with soil. In this study, nested polymerase chain reaction (PCR) and denaturing gradient gel electrophoresis (DGGE) were combined to explore the bacterial and fungal community successions in soil treated with 5 and 20 mg/kg of chlorpyrifos. Furthermore, isolates capable of efficiently decomposing chlorpyrifos were molecular-typed using enterobacterial repetitive intergenic consensus-PCR (ERIC-PCR). Under the experimental conditions, degradation of chlorpyrifos in soil was interpreted with the first-order kinetics, and the half-lives of chlorpyrifos at 5 and 20 mg/kg doses were calculated to be 8.25 and 8.29 d, respectively. DGGE fingerprint and principal component analysis (PCA) indicated that the composition of the fungal community was obviously changed with the chlorpyrifos treatment, and that samples of chlorpyrifos treatment were significantly separated from those of the control from the beginning to the end. While for the bacterial community, chlorpyrifos-treated soil samples were apparently different in the first 30 d and recovered to a similar level of the control up until 60 d, and the distance in the PCA between the chlorpyrifos-treated samples and the control was getting shorter through time and was finally clustered into one group. Together, our results demonstrated that the application of chlorpyrifos could affect the fungal community structure in a quick and lasting way, while only affecting the bacterial community in a temporary way. Finally, nine typical ERIC types of chlorpyrifos-degrading isolates were screened. PMID:24711353

    Full Text Available Salmonelose é a infecção bacteriana de origem alimentar mais freqüente no Paraná, Brasil, e os surtos estão associados, principalmente, ao consumo de ovos, carne de aves e derivados. Os objetivos deste trabalho foram identificar os sorovares de Salmonella isolados de carcaças de frango e caracterizá-los molecularmente por REP e ERIC-PCR, assim como identificar os fagotipos de Salmonella Enteriditis. Dos 25 isolados de Salmonella spp. analisados, 18 foram identificados como Enteriditis, 4 como Braenderup, 2 como Worthington e 1 como infantis. Dos 18 isolados de Enteriditis, 14 foram PT4, 2 PT4a, 1 PT7 e 1 RDNC, por se tratar de colônia rugosa. REP-PCR forneceu padrão eletroforético distinto de 10 a 13 bandas distribuídas entre 120 e 2072 pb para cada sorovar diferente testado. A ERIC-PCR mostrou um padrão de 4 a 5 bandas entre 180 e 1000 pb e foi menos discriminativa quando comparada à REP-PCR. Os resultados encontrados confirmaram que a fagotipagem é uma ferramenta útil e discriminativa para o sorovar Enteriditis. Apesar do pequeno número de sorovares testados, os resultados sugerem que a REP-PCR parece ser um método atrativo a ser utilizado no futuro para a discriminação preliminar de sorovares de Salmonella.Salmonellosis is the most prevalent bacterial food-borne disease in the State of Paraná, Brazil, and the outbreaks are often associated with consumption of poultry products.

    2016-09-01

    Full Text Available In The Lady and the Duke (2001, Eric Rohmer provides an unusual and “conservative” account of the French Revolution by recurring to classical and yet “revolutionary” means. The interpolation between painting and film produces a visual surface which pursues a paradoxical effect of immediacy and verisimilitude. At the same time though, it underscores the represented nature of the images in a complex dynamic of “reality effect” and critical meta-discourse. The aim of this paper is the analysis of the main discursive strategies deployed by the film to disclose an intermedial effectiveness in the light of its original digital aesthetics. Furthermore, it focuses on the problematic relationship between image and reality, deliberately addressed by Rohmer through the dichotomy simulation/illusion. Finally, drawing on the works of Louis Marin, it deals with the representation of history and the related ideology, in order to point out the film’s paradoxical nature, caught in an undecidability between past and present.

    Medical research projects often require more biological material than can be supplied by a single biobank. For this reason, a multitude of strategies support locating potential research partners with matching material without requiring centralization of sample storage. Classification of different strategies for biobank networks, in particular for locating suitable samples. Description of an IT infrastructure combining these strategies. Existing strategies can be classified according to three criteria: (a) granularity of sample data: coarse bank-level data (catalogue) vs. fine-granular sample-level data, (b) location of sample data: central (central search service) vs. decentral storage (federated search services), and (c) level of automation: automatic (query-based, federated search service) vs. semi-automatic (inquiry-based, decentral search). All mentioned search services require data integration. Metadata help to overcome semantic heterogeneity. The "Common Service IT" in BBMRI-ERIC (Biobanking and BioMolecular Resources Research Infrastructure) unites a catalogue, the decentral search and metadata in an integrated platform. As a result, researchers receive versatile tools to search suitable biomaterial, while biobanks retain a high degree of data sovereignty. Despite their differences, the presented strategies for biobank networks do not rule each other out but can complement and even benefit from each other.

    The diagnostic criteria for CLL rely on morphology and immunophenotype. Current approaches have limitations affecting reproducibility and there is no consensus on the role of new markers. The aim of this project was to identify reproducible criteria and consensus on markers recommended for the diagnosis of CLL. ERIC/ESCCA members classified 14 of 35 potential markers as "required" or "recommended" for CLL diagnosis, consensus being defined as >75% and >50% agreement, respectively. An approach to validate "required" markers using normal peripheral blood was developed. Responses were received from 150 participants with a diagnostic workload >20 CLL cases per week in 23/150 (15%), 5-20 in 82/150 (55%), and 97% concordance with current approaches. A pilot study to validate staining quality was completed in 11 centers. Markers considered as "required" for the diagnosis of CLL by the participants in this study (CD19, CD5, CD20, CD23, Kappa, and Lambda) are consistent with current diagnostic criteria and practice. Importantly, a reproducible approach to validate and apply these markers in individual laboratories has been identified. Finally, a consensus "recommended" panel of markers to refine diagnosis in borderline cases (CD43, CD79b, CD81, CD200, CD10, and ROR1) has been defined and will be prospectively evaluated. © 2017 International Clinical Cytometry Society. © 2017 The Authors.

    Every historian should answer two questions related to each other, i. e. what is the relationship between history and reality and what is that between historiography and reality. Moreover, Chinese historians should answer other two questions also re-lated to each other, namely what is the relationship between China and the West and what is that between Chinese culture and Western culture. Based on their own outlook on the ancient and the present as well as on China and the West, every conscious Chinese historian of the 20 th century was bound to cherish a definite sense of responsi-bility and determined what role they played and what way they chose when taking on this responsibility. The present paper expounds Prof. Chen Yuan’ s answers to the above questions andhis practice concerned with them in the four stages of his lifetime.

    1987-02-01

    This report describes some special energy efficient measures incorporated in the construction of a modestly-priced two and a half storey frame house with a floor area of 108 m{sup 2}. The house was built facing south, on a south-sloping lot with a thick stand of Jack Pine on the north side. The major energy efficient measures are: continuous air-vapour barrier and high insulation level to make the house as air-tight as possible; the use of passive solar heat which is expected to supply 37% of the annual heating requirements; a crawlspace plenum which draws hot air from the top of the house and recirculates it under the first floor; and use of horizontal strapping on which all wall partitions, electrical and plumbing work was done in order not to break the continuous air-vapour barrier and which itself provides extra insulation. The cost of making the house energy efficient was $2,500. The price of the house on completion was projected to be $65,000. The cost for the energy efficiency measures is 4% of the total. The Allen house is a good example of how an investment of a small percentage of the total cost, and about 67 hours of work, can result in an energy efficient house. The resulting savings on energy bills can be quite significant and can mean a return on the investment within 5 years. 3 figs., 1 tab.

    Although the biogeochemical processes underlying in situ bioremediation technologies are increasingly well understood, field-scale heterogeneity (both physical and biogeochemical) remains a major obstacle to successful field-scale implementation. In particular, slow release of contamination from low-permeability regions (primarily by diffusive/dispersive mass transfer) can hinder the effectiveness of remediation. The research described in this report was conducted in conjunction with a project entitled ''In Situ Immobilization of Uranium in Structured Porous Media via Biomineralization at the Fracture/Matrix Interface'', which was funded through the Field Research element of the former NABIR Program (now the Environmental Remediation Sciences Program) within the Office of Biological and Environmental Research. Dr. Timothy Scheibe (Pacific Northwest National Laboratory) was the overall PI/PD for the project, which included Scott Brooks (Oak Ridge National Laboratory) and Eric Roden (formerly at The University of Alabama, now at the University of Wisconsin) as separately-funded co-PIs. The overall goal of the project was to evaluate strategies that target bioremediation at interfaces between high- and low-permeability regions of an aquifer in order to minimize the rate of contaminant transfer into high-permeability/high fluid flow zones. The research was conducted at the Area 2 site of the Field Research Center (FRC) at Oak Ridge National Laboratory (ORNL). Area 2 is a shallow pathway for migration of contaminated groundwater to seeps in the upper reach of Bear Creek at ORNL, mainly through a ca. 1 m thick layer of gravel located 4-5 m below the ground surface. Hydrological tracer studies indicate that the gravel layer receives input of uranium from both upstream sources and from diffusive mass transfer out of highly contaminated fill and saprolite materials above and below the gravel layer. We sought to test the hypothesis that injection of electron donor into this

    2009-01-01

    In this paper, based on the stability theorem of linear fractional systems, a necessary condition is given to check the chaos synchronization of fractional systems with incommensurate order. Chaos synchronization is studied by utilizing the Pecora-Carroll (PC) method and the coupling method. The necessary condition can also be used as a tool to confirm results of a numerical simulation. Numerical simulation results show the effectiveness of the necessary condition.

    2017-09-01

    The extensive use of β-lactam antibiotics has led to emergence and spread of extended-spectrum β-lactamases (ESBLs). This study was conducted to investigate the prevalence of 7 different ESBL genes (bla TEM , bla SHV , bla CTX-M , bla VEB , bla PER , bla GES , and bla OXA-10 ) and O25b-ST131 high-risk clone among 61 clinical isolates of Escherichia coli. Also, one broad-spectrum β-lactamase (bla OXA-1 ) was investigated. This study was also constructed to evaluate iodometric overlay method in detection of ESBL production. Phenotypic identification of E. coli isolates using API 20E revealed 18 distinct biotypes. DNA fingerprinting using enterobacterial repetitive intergenic consensus polymerase chain reaction (ERIC-PCR) differentiated all isolates into 2 main phylogenetic groups with 60 distinct genetic profiles. Elevated values of minimal inhibitory concentration (MIC) 50 and MIC 90 for third- and fourth-generation cephalosporins were observed. Phenotypic tests revealed that 85.24% of isolates were ESBL producers. The incidence rates of bla TEM , bla SHV , bla CTX-M , bla GES , bla OXA-1 , and bla OXA-10 among E. coli ESBL producer phenotype were 69.23%, 25%, 96.15%, 3.85%, 11.54%, and 48%, respectively. On the other hand, bla VEB and bla PER were not detected. Sequencing of bla TEM and bla SHV revealed that bla TEM-214 and bla SHV-11 were the most prevalent variants. Group characterization of bla CTX-M revealed that bla CTX-M-1 was the most prevalent group of bla CTX-M family. It was found that 30.77% of E. coli ESBL producers belonged to O25b-ST131 clone harboring bla CTX-M-15 . This study concluded that iodometric overlay method was 100% sensitive in detection of ESBL production. To our knowledge, this is the first Egyptian study that declares the emergence of E. coli O25b-ST131 harboring bla GES .

    Spectra taken by the IRS (Houck et al. 2004ApJS..154...18H) on the Spitzer space telescope (Werner et al. 2004ApJS..154....1W) are now publicly available. These spectra are produced using the bksub.tbl products from SL and LL modules of final SSC pipeline, version 18.18. From the IRS data archive, we found a collection of 16986 low-resolution spectra. The spectra are merged by four slits: SL2 (5.21-7.56 μm), SL1 (7.57-14.28 μm), LL2 (14.29-20.66 μm), and LL1 (20.67-38.00 μm). As crystalline silicates have no features in the SL2 band, we choose the spectra that include all the other three bands: SL1, LL2, and LL1 so that the object has a continuous spectrum from about 7.5-38 μm. In this way, five of the seven infrared complexes of crystalline silicates are covered, i.e., the 10, 18, 23, 28, and 33 μm complexes. (5 data files).

    Full Text Available Common ragweed (Ambrosia artemisiifolia is spreading on agricultural fields in Germany, mainly in Brandenburg and Bayern. Competitive crops like winter cereals and oilseed-rape can reduce growth of this plant better than spring crops. In maize or cereals a chemical control is possible, but problems may arise because of the late emergence of ragweed and its high ability to regrowth. In crops like sunflower or lupines herbicide choice is limited and thus preventive control measures are crucial. An integrated approach is needed in order to avoid yield losses and to stop the spreading of ragweed in Germany.

Cleaning treatments can remove dust, soil, impurities or even heavy metals and pesticide residues on agricultural products. But effects of cleaning treatments on the heavy metal content of P. notoginseng roots have still not been studied. In order to elucidate this issue, the effects of five different cleaning treatments (CK, no treatment; T1, warm water (50°C) washing; T2, tap water (10°C) washing; T3, drying followed by polishing; and T4, drying followed by tap water (10°C) washing) on P. notoginseng roots' heavy metal (Cu, Pb, Cd, As and Hg) contents were studied. The results showed that heavy metal (all five) content in the three parts all followed the order of hair root > rhizome > root tuber under the same treatment. Heavy metal removals were in the order of Hg > As > Pb > Cu > Cd. Removal efficiencies of the four treatments were in the order of T2 > T1 > T3 > T4. Treatments (T1-T4) could decrease the contents of heavy metal in P. notoginseng root significantly. Compared with the requirements of WM/T2-2004, P. notoginseng roots' heavy metal contents of Cu, Pb, As and Hg were safe under treatments T1 and T2. In conclusion, the cleaning process after production was necessary and could reduce the content of heavy metals significantly. Fresh P. notoginseng root washed with warm water (T2) was the most efficient treatment to remove heavy metal and should be applied in production.

    Full Text Available Seeking the identification of Angiostrongylus cantonensis as a potential etiological agent of three clinical cases of eosinophilic meningitis, mollusc specimens were collected in the state of Espírito Santo, Brazil. The snails were identified as Sarasinula marginata (45 specimens, Subulina octona (157, Achatina fulica (45 and Bradybaena similaris (23. Larvae obtained were submitted to polymerase chain reaction and restriction fragment length polymorphism diagnosis. Their genetic profile were corresponded to A. cantonensis. Rattus norvegicus experimentally infected with third-stage larvae, developed menigoencephalitis, and parasites became sexually mature in the lungs. Additionally, larvae obtained from A. fulica snails, from São Vicente, state of São Paulo, also showed genetic profiles of this nematode. This is the first record of Brazilian molluscs infected with this nematode species.

    The Spitzer observations of the Bridge were obtained as part of the Legacy Program "Surveying the Agents of Galaxy Evolution in the Tidally-Stripped, Low-Metallicity Small Magellanic Cloud" (SAGE-SMC; Gordon et al. 2011AJ....142..102G). These observations included images taken at 3.6, 4.5, 5.8, and 8.0 um bands with the InfraRed Array Camera (IRAC) and at 24, 70, and 160 um bands with the Multiband Imaging Photometer for Spitzer (MIPS). The details of data processing are given in Gordon et al. (2011AJ....142..102G). To construct multi-wavelength SEDs for sources in the Spitzer catalog, we have expanded it by adding photometry from optical and NIR surveys covering the Bridge, i.e., BRI photometry from the Super COSMOS Sky Surveys (SSS; Hambly et al. 2001MNRAS.326.1279H) and JHKs photometry from the Two Micron All Sky Survey (2MASS; Skrutskie et al. 2006AJ....131.1163S, Cat.

    We tried to select a large number of blazars with reliable redshift, radio core and extended radio luminosity at 1.4GHz. Firstly, we considered the following samples of blazars to get the radio core luminosity and extended luminosity at 1.4GHz: Kharb et al. (2010, J/ApJ/710/764), Antonucci & Ulvestad (1985ApJ...294..158A), Cassaro et al. (1999A&AS..139..601C), Murphy et al.

    The Baryon Oscillation Spectroscopic Survey (BOSS: Eisenstein et al. 2011AJ....142...72E; Paris et al. 2012, Cat. VII/269) is the main dark-time legacy survey of the third stage of the SDSS, which used the same 2.5-m telescope (Gunn et al. 2006AJ....131.2332G; Ross et al. 2012, J/ApJS/199/3) as the first and second stages of the SDSS (hereafter SDSS-I/II). SDSS-I/II spectra have a wavelength coverage from 3800-9200Å with a spectral resolution of 1800-2200 (e.g. York et al. 2000AJ....120.1579Y). BOSS spectra span a range from 3600-10500Å at a resolution of 1300-2500 (Paris et al. 2012, Cat. VII/269). During the first two years, BOSS detected 87822 quasars over an area of 3275 deg2, including 7932 quasars that were observed by SDSS-I/II as well. Quasars observed by both SDSS-I/II and BOSS provide a remarkable chance to study the variabilities of absorption lines in a large population. Throughout this work, we take the quasar emission redshifts provided by Hewett & Wild (2010, J/MNRAS/405/2302, http://das.sdss.org/va/HewettWilddr7qso_newz/) directly. (2 data files).

    Directory of Open Access Journals (Sweden)

    Reviewed by Wu Jing 吴晶

    2018-05-01

    Full Text Available Published in 2002, Love in Lhasa is Baima's first novel. The background is the 1980s at a time when China was engaging in fast-paced development of industrialization and commercialization as part of the Reform and Opening Up that began in the late 1970s. Most of the novel's episodes are set on the Tibetan Plateau where local Tibetans are affected by the trend of modernization. Young people in particular have increased opportunities to go out and see the world and also experience more challenges in dealing with issues of self-identity, and exploring the meaning of their existence. Against such a fast-changing social background, Tibetan women are faced with poignant life choices, especially as compared to traditional women. The novel's plot unfolds with the parallel life trajectories of the two female characters, Langsa and Yama, who are classmates and close friends at Tibet Military College. After graduation, the two young women leave the army and work in non-military areas as nurses. Langsa, the narrator, falls in love with a pilgrim, Varma, who comes from an isolated part of Tibet where Tibetan, Hui, and Han nationalities live together. They enjoy their otherworldly, extremely romantic relationship, and in the end, choose to live a reclusive life in the unknown hinterlands of Tibet. In contrast, Yama, the heroine, undergoes more complicated love experiences. Yama is the focus of this novel, embodying qualities of a "lost girl," such as beauty, rebelliousness, freedom-loving, desire, dreamer, degradation, and despair. After a pre-marriage affair with Di, a young Han man, she marries Zedan, a Tibetan, and her first real love. Disappointed by domestic life, she succumbs to temptation and has an extra-marital affair with Xu Nan in Shanghai. ...

    2004-01-01

    We are on the verge of establishing an internal electricity market. We are trying to promote a further development of the electrical interconnections between Member States to promote that market and trade in electricity. If we are successful in our efforts, the mix of power production sources will have a bearing not only nationally but also internationally in the internal market. There will be increased electricity trade between nuclear and non-nuclear countries. There will be air pollution from fossil fired power plants going from one country to another. As Our Union must keep the nuclear option open, for reasons of security of supply, for meeting our Kyoto commitments and for providing our citizens with affordable electricity, now and in the future. The Commission is working to set the conditions for a public acceptance or, at least, understanding of the merits of the nuclear option by reinforcing its safety and security in the short and the long term. When these conditions will be met, discussions on a particular energy source will necessarily and primarily have to be informed by economic reasons. In the light of the above considerations, the adoption of the nuclear package would contribute to the acceptance of nuclear energy and dispassionate the debate on the future of this option. Therefore, I count on the support of Slovakia to the proposals of the Commission, in particular on the need for binding measures and not mere recommendations which already exist at the international level.

    The French minister of energy, E. Besson said that the study of the Court of Auditors on the real costs of nuclear energy confirmed the competitiveness of nuclear power. The Court of Auditors confirmed also that public expenditures in favor of nuclear energy are balanced by the gain through the tax on nuclear facilities. The Court of Auditors confirms also that dismantlement charges and charges for the management of radioactive wastes are included in the present costs of nuclear energy at an adequate level with today's knowledge. The total cost of nuclear energy is very competitive, it ranges form 32.5 euros/MWh to 49.5 euros/MWh according to the cost accounting method used. One of major parameters for cost elaboration is the knowledge of the lengths of the operating life of the power plant. The longer the extension is, the lower is the investment cost. (A.C.)

    Greengard, Paul

    2013-01-01

    Paul Greengard was born in New York City in 1925. After completing high school, he served three years in the US Navy during World War II and then completed his bachelor's degree at Hamilton College where he majored in physics and mathematics. He obtained a PhD in biophysics from Johns Hopkins University in 1953 and pursued postdoctoral training with Wilhelm Feldberg at the National Institute for Medical Research in England. After eight years as head of biochemistry at Geigy, and sabbaticals at Albert Einstein College of Medicine and Vanderbilt University, he joined the Yale University faculty as a full professor of pharmacology in 1968. While he was at Yale, Greengard's laboratory performed groundbreaking research, which demonstrated a role for cyclic nucleotides, protein kinases and protein phosphatases, and their protein substrates in the regulation of synaptic transmission. In 1983, Greengard moved to The Rockefeller University, where he has since served as the Vincent Astor Professor and Head of the Laboratory of Molecular and Cellular Neuroscience. Greengard's paradigm-shifting research has continued at Rockefeller and has informed our understanding and possible treatment of a host of brain disorders, including schizophrenia, Alzheimer's disease, Parkinson's disease, and depression. He is the author of more than 950 research articles and reviews. Greengard has received numerous awards and honors, including the Nobel Prize in Physiology or Medicine in 2000, the Metropolitan Life Foundation Award for Medical Research, The National Academy of Sciences Award in Neuroscience, the Ralph W. Gerard Prize in Neuroscience for the Society for Neuroscience, and the Karolinska Institutet's Bicentennial Gold Medal. He is a member of the US National Academy of Sciences and the Institute of Medicine of the National Academies. The following interview was conducted on May 29, 2012.

    Roden, Eric E.

    2009-01-01

    This report summarizes research conducted in conjunction with a project entitled 'Reaction-Based Reactive Transport Modeling of Iron Reduction and Uranium Immobilization at Area 2 of the NABIR Field Research Center', which was funded through the Integrative Studies Element of the former NABIR Program (now the Environmental Remediation Sciences Program) within the Office of Biological and Environmental Research. Dr. William Burgos (The Pennsylvania State University) was the overall PI/PD for the project, which included Brian Dempsey (Penn State), Gour-Tsyh (George) Yeh (Central Florida University), and Eric Roden (formerly at The University of Alabama, now at the University of Wisconsin) as separately-funded co-PIs. The project focused on development of a mechanistic understanding and quantitative models of coupled Fe(III)/U(VI) reduction in FRC Area 2 sediments. The work builds on our previous studies of microbial Fe(III) and U(VI) reduction, and was directly aligned with the Scheibe et al. ORNL FRC Field Project at Area 2. Area 2 is a shallow pathway for migration of contaminated groundwater to seeps in the upper reach of Bear Creek at ORNL, mainly through a ca. 1 m thick layer of gravel located 4-5 m below the ground surface. The gravel layer is sandwiched between an overlying layer of disturbed fill material, and 2-3 m of undisturbed shale saprolite derived from the underlying Nolichucky Shale bedrock. The fill was put in place when contaminated soils were excavated and replaced by native saprolite from an uncontaminated area within Bear Creek Valley; the gravel layer was presumably installed prior to addition of the fill in order to provide a stable surface for the operation of heavy machinery. The undisturbed saprolite is highly weathered bedrock that has unconsolidated character but retains much of the bedding and fracture structure of the parent rock (shale with interbedded limestone).

    M. Sandtner

    Full Text Available The article shows that the computer-aided, analogous-visual, stereometric interpretation of large-scale colour-infrared (CIR aerial photographs and subsequent data processing in a Geographical Information System (GIS can provide fundamental data necessary to describe aspects of urban ecology in a scale relevant for city-planning. This is exemplified by an evaluation of urban areas concerning their climates and airpollution using maps of urban surfaces (scale1:2500. An argumentation relying on such detailed and current basic data can stress the importance of environmental aspects in contrast to competing public and private interests in the process of city planning.

  7. Chem TV: Choices I, v. 1.5.1 (by B. A. Luceigh, P. Ngo, and J. Chen)

    Kraig Steffen, L.

    1999-08-01

    CHEM TV: Sunland, CA, 1998. 24.95, students; 59.95, faculty. This CD-ROM presents a series of interactive overviews and drills for students of organic chemistry. The material covered is generally taught in the first semester. This suite is much more than a simple presentation of material and, for students sufficiently motivated to take the time and work with the problems, will provide valuable review. Five interactive spaces are provided: concentration drills that emphasize recall of related structures/names, reagents/reactions, and stereochemistry; a structural review based on epinephrine; interactive synthesis projects; arcade game reagent review; and a set of timed self-tests. The CD-ROM installed and ran without problem on a Power PC Mac and on a Pentium running Windows 95. The program did fail to run when a student reviewing it switched to a very new version of Windows Quick Time. Most of the drills ran without a problem, although at times it was unclear how to respond to queries. I turned off the music, which would be much less annoying if the loops were simply longer. Publishers are flooding the market with add-on computer-based materials for the various levels of chemistry. Many constitute little more than a stack of overheads. This is one that may be of sufficient value to warrant the extra cost. A large number of examples are provided for many of the areas covered. Most of the graphical interfaces are clear and easy to manipulate, with the exception of a couple of mechanistic screens that had hard-to-figure-out arrows. Two sections, or modules, are of special note. The first of these is the synthesis challenges, where students must choose reactants, reagents, and reaction conditions for a particular reaction. These synthesis problems are well thought out and can be challenging. It is unfortunate that there are only five of them. The Self-Tests module is also of great practical value, forcing students to work through a variety of topics (200 problems) with limited time allotted per test. The structures are clear and easy to view and include a large number of three-dimensional molecular models that help make the connection between simple line drawings and actual molecules. More feedback information on incorrect answers would be nice, although it is obvious that this can balloon into an unworkable situation if every possible "wrong" answer is considered. The structure summary, which uses a single complicated molecule to review a large range of structural topics, is a good integrated look at bonding, stereochemistry, and conformational analysis. The concentration game is informative, albeit a bit obtuse on a few of the answers! The selection drills, a shooting gallery game with various chemical targets, seems a bit silly, but then if one can learn to recognize all the major reducing agents by snagging butterflies with faux nets than this could be helpful! With its varying levels of difficulty, this set of modules should be accessible even to weaker students and yet will provide a challenge for the more advanced. A great future addition would be an interactive module builder that allows faculty to modify existing questions and add their own. How can one effectively use this program? The relatively low cost does make it accessible for individual students to purchase, perhaps as a "recommended" item for the class. Another very practical option is to purchase 5-10 copies (assuming a class size of around 30-40) and make them available through a common computer laboratory (or an appropriate network site-license arrangement) or for check-out to small groups of students. One drawback is that only about 1/3 of the major topics that fill the year in organic are covered. I have used some of the drills as in-class interactive examples with a projector and laptop. This type of interactive tutorial-quiz-based program is a welcome change from the simple textbook on a CD-ROM approach. Given easy access to computers and an environment that encourages individual and small-group interactions, I believe this program can be a worthwhile aid for students of organic chemistry.

    In the General Catalog of Ap and Am stars (Renson & Manfroid 2009, Cat. III/260) 8265 stars are included in which, as Renson & Manfroid (2009, Cat. III/260) described, only 426 stars are of the "well known confirmed sample". We take these 426 stars as our working sample. The cross-identifications of 2MASS/WISE counterparts for all Ap, Am, and HgMn stars listed in this paper are made from Cutri et al. (2012, Cat. II/311) by using the radius of 2 arcsec. All 426 Ap, Am, and HgMn stars have 2MASS and/or WISE counterparts, which are listed in Table 3. The cross-identifications of IRAS counterparts are made according to the positional error ellipse of the source, because it has a 95% confidence level (IRAS Explanatory Supplement, Beichman et al. 1988, Cat. II/274). Finally, 202 stars are found to have the IRAS counterparts from IRAS PSC/FSC, which is listed in Table 4. (5 data files).

    Full Text Available In the present work Trichodina reticulata and T. nobilis (Ciliophora: Trichodinidae are morphologically characterised from ornamental freshwater fish culture in the State of Santa Catarina, Brazil. The prevalence of infection and a list of comparative measurements are discussed. We examined "southern platyfish" Xiphophorus maculatus (n = 35, "goldfish" Carassius auratus (n = 31, "guppy" Poecilia reticulata (n = 20, "sailfin molly" Poecilia latipinna (n = 6, "beta" Betta splendens (n = 2 and "spotted headstander" Chilodus punctatus (n = 1. After being anesthetised in a benzocaine solution, fishes were examined for parasitological evaluation. A total of 51.57% fishes were parasitised by Trichodina spp. Carassius auratus was the most parasitised species, followed by X. maculatus and P. reticulata. Beta splendens, C. punctatus and P. latipinna were not parasitised by any trichodinid species. Two species of Trichodina were collected from the skin of fish: T. nobilis was found in C. auratus, P. reticulata and X. maculatus and T. reticulata was only observed in C. auratus. The importance of adequate handling in ornamental fish culture are also discussed.

    2013-01-01

    Paragaleus tengi was previously considered to be the only member of this genus occurring in the Western Pacific, with Paragaleus randalli occurring in the Indian Ocean and allopatric in distribution. Recent molecular and morphological studies showed that P. randalli also occurs in the Western Pacific with records from Thailand, Malaysia and Indonesia previously mostly incorrectly attributed to P. tengi. This paper provides a redescription of P. tengi and confirms the presence of P. randalli from off Taiwan in the western North Pacific. These two species are morphologically very similar in appearance but differ in meristics, dentition, some coloration attributes and minor morphological characters. The conservation status of these two species needs to be reassessed based on this new information.

  2. How Structural Deficiencies Hamper Estonia’s Catching-up Process. Strukturschwächen als Hemmnis für Estlands Aufholprozess

    Directory of Open Access Journals (Sweden)

    Klaus Schrader

    2016-10-01

    Full Text Available Estonia is widely regarded as a paramount example for a successful transformation of a socialist economic system to a functioning market economy. Against the backdrop of this positive image which contrasts strongly with the crisis scenarios in Southern Europe the remaining problems of Estonia are often ignored. Estonia has hardly succeeded in catching-up economically with the richer countries of the EU. In this paper the authors raise the question why the catching-up process of Estonia is not as successful as it could have been expected from the policy performance during the last decades. It turns out that Estonia faces a serious productivity problem, particularly in the manufacturing sector producing tradable goods which is normally the driving engine behind economic and technological catching-up. The Estonian economy has failed to undergo the necessary structural change towards technologically more advanced employment structures and export patterns. Accordingly, Estonian economic policy needs to create a suitable business environment to support this kind of structural change.

    1983-01-01

    The oil-intensive development pattern applied by Venezuela in the last 40 years has limited the regional economic growth of the rural areas while the big metropolitan areas are suffering an accelerated and irrational population increase. The corollary of this rapid industrialization has been excessive urbanization, high rate of unemployment, rural emigration and a lack of services in more than half the territory. The very centralized energy sector does not even consider settlements with less than 500 people. The need for a more rational use of the land, where space, water, energy and mineral resources are available, has induced the utility company (CADAFE) and the Government to test the use of renewable energy sources in a remote village of the Federal Territory of Amazon. Various photovoltaic generators are used to operate some of the basic services of the community. This installation, designed by the authors and constructed by Architect Nihls Grillet, Consogri International CA, uses equipment provided by Leroy Somer, France-Photon, Pompes Guinard and has been operating successfully since June 1981.

    Dysregulated metabolism is a hallmark of cancer, manifested through alterations in metabolites. We performed metabolomic profiling on 138 matched clear cell renal cell carcinoma (ccRCC)/normal tissue pairs and found that ccRCC is characterized by broad shifts in central carbon metabolism, one-carbon metabolism, and antioxidant response. Tumor progression and metastasis were associated with metabolite increases in glutathione and cysteine/methionine metabolism pathways. We develop an analytic pipeline and visualization tool (metabolograms) to bridge the gap between TCGA transcriptomic profiling and our metabolomic data, which enables us to assemble an integrated pathway-level metabolic atlas and to demonstrate discordance between transcriptome and metabolome. Lastly, expression profiling was performed on a high-glutathione cluster, which corresponds to a poor-survival subgroup in the ccRCC TCGA cohort. Copyright © 2017 Elsevier Inc. All rights reserved.

  10. An enhanced rheometer inertia correction procedure (ERIC) for the study of gelling systems using combined motor-transducer rheometers

    The rheological characterisation of viscoelastic materials undergoing a sol-gel transition at the Gel Point (GP) has important applications in a wide range of industrial, biological, and clinical environments and can provide information regarding both kinetic and microstructural aspects of gelation. The most rigorous basis for identifying the GP involves exploiting the frequency dependence of the real and imaginary parts of the complex shear modulus of the critical gel (the system at the GP) measured under small amplitude oscillatory shear conditions. This approach to GP identification requires that rheological data be obtained over a range of oscillatory shear frequencies. Such measurements are limited by sample mutation considerations (at low frequencies) and, when experiments are conducted using combined motor-transducer (CMT) rheometers, by instrument inertia considerations (at high frequencies). Together, sample mutation and inertia induced artefacts can lead to significant errors in the determination of the GP. Overcoming such artefacts is important, however, as the extension of the range of frequencies available to the experimentalist promises both more accurate GP determination and the ability to study rapidly gelling samples. Herein, we exploit the frequency independent viscoelastic properties of the critical gel to develop and evaluate an enhanced rheometer inertia correction procedure. The procedure allows acquisition of valid GP data at previously inaccessible frequencies (using CMT rheometers) and is applied in a study of the concentration dependence of bovine gelatin gelation GP parameters. A previously unreported concentration dependence of the stress relaxation exponent (α) for critical gelatin gels has been identified, which approaches a limiting value (α = 0.7) at low gelatin concentrations, this being in agreement with previous studies and theoretical predictions for percolating systems at the GP.

A central aim of the project will be to manufacture specific vehicle molecules whose tumor affinity and suitability for radioactive coupling have already been proven through laboratory trials on animals and cell cultures at the Department of Nuclear Medicine, University of Cologne and to label it with Y- 90. The vectors to be used to transport radionuclides into tumor tissue for treatment are antibodies against lymphomas and neuroblastomas. The technology applied for coupling Y-90 to various antibodies has been developed to a high level in Cologne and is now ready to be transferred and adapted to GMP (Good Manufacturing Practice) conditions. The antibody against NHL can be acquired commercially and must then be modified for binding to the therapeutically active nuclide Y-90. Similarly, the antibody against neuroblastoma must also be modified to bind to Y-90 but is produced in Cologne. To improve the therapeutic value of antibodies we tried to introduce the pretargeting method.

    We performed an observational study on the efficacy of bendamustine and rituximab as first salvage regimen in chronic lymphocytic leukemia. In an intention-to-treat analysis including 237 patients, the median progression free survival was 25 months. The presence of del(17p), unmutated IGHV and advanced stage were associated with a shorter progression free survival at multivariate analysis. The median time-to-next treatment was 31.3 months. Front-line treatment with a chemoimmunotherapy regimen was the only predictive factor for a shorter time to next treatment at multivariate analysis. The median overall survival was 74.5 months. Advanced Binet stage (i.e. III-IV or C) and resistant disease were the only parameters significantly associated with a shorter OS. Grade 3-5 infections were recorded in 6.3% of patients. A matched-adjusted indirect comparison with ibrutinib given second-line within named patient programs in the United Kingdom and in Italy was carried out with overall survival as objective endpoint. When restricting the analysis to patients with intact 17p who had received chemoimmunotherapy in first line, the overall survival did not differ between patients treated with ibrutinib (63% alive at 36 months) and patients treated with BR (74.4% alive at 36 months). BR is an efficacious first salvage regimen in chronic lymphocytic leukemia in a real-life population, including the elderly and unfit patients. BR and ibrutinib may be equally effective in terms of overall survival when used as first salvage treatment in patients without 17p deletion. ClinicalTrials.gov identifier: NCT02491398.

    Libraries are important social institutions that preserve and communicate human culture and knowledge. From the beginning of 1990s, the digital library has grown up rapidly based on the progress of the Internet. Libraries and educational institutions should be actively involved in digital library research and development. The Taiwan libraries’ history can be divided into four stages: Japanese occupation period, reconstruction period, growth period and strong period. In these processes, many events and libraries with rich materials that can be developed into a digital library. Graduate Institute of Library, Information and Archival Studies, National Chengchi University, planned the Digital Library Pilot Study on Taiwan Libraries’ History and got the university support. The pilot study objectives include: (1 exploring the digital library model on Taiwan libraries' history; (2 constructing digital library to support education and research in information and library science; (3 developing Metadata standards of library documents and heritage; (4 digitalizing documents and heritage to build digital collections (5 developing digital library systems and technology; (6 researching browsing and search functions of the digital library; (7 exploring the model of the digital library supports e-learning. In this pilot study, we developed six Metadata standards, built 746 digital resources, constructed a digital library system and web site, and proposed the conclusions and suggestions finally.

    东方叶肢介(Eosestheria)是著名热河生物群中最为常见的一类甲壳动物,关于它的形态、壳瓣结构及微细纹饰特征的研究已相当详尽,但一直没有关于其软体构造的报道。本文描述的凌源东方叶肢介(Eosestheria lingyuanensis)采自辽宁北票市尖山沟村,产于下白垩统义县组的尖山沟夹层。这些软体构造包括:头部形态、眼、闭壳肌痕、雄性执握肢、体节、消化道及尾节等。通过与现生叶肢介软体形态构造比较,显示其与刺尾亚目的蚌壳虫科的代表最为亲近。从而为探讨化石与现生叶肢介之间的演化关系及建立高一级的统一分类,提供了有价值的依据。%The clam shrimp Eosestheria is an extraordinarily abundant and important member of the con-chostracan fauna from the famous Jehol Biota. Here the occurrence of partial soft body preservation in E. Lingyuanensis is reported for the first time, occurring as impressions, inside the valve, of the head, eye, adductor muscle scar, male claspers, digestive tube, and telson.The exceptionally preserved specimens were found in the Lower Cretaceous Yixian Formation at Jianshangou village, near Beipiao, in Liaoning Province of NE China. The preservation of soft parts in conchostracans is significant partly because its occurrence is very rare-known previously only from about 16 species . Worldwide and several of which are actually much less complete than the present material. Soft body characteristics are also important for accurate taxonomic determination and assessment of relationships. For example, all conchostracan males have the first pair of trunk limbs modified to form so called 'claspers', which hold to the female during mating. Some modification of the second pair of trunk limbs is seen in lae-vicaudatan conchostracans, two species of which are also known as fossils with soft body parts, butthe second pair appears not to be clasper-like in form. Eosestheria lingyuanensis on the other hand has two pairs of clearly defined claspers as in spini-caudatan conchostracans. Furthermore in its more distinct growth lines and acute rostrum as well as its two pairs of claspers it clearly belongs to the suborder Spinicaudata. Within that group, although it is similar to the Cyzicidae in its rostrum lacking an apical spine and in its short stout telson, it differs in its less developed occipital notch and larger palp with a row of pores.Although the name Conchostraca is commonly used in fossil and extant literature, recent molecular and morphological analyses show that the 'Conchostraca' appears not to be a monophyletic group. As such it has no taxonomic meaning. It has therefore been abandoned as a taxonomic unit by many authors. However, Shen et al. (2006) retain use of the 'Conchostraca', which include five suborders. Laevicaudata, Spinicaudata, Cycles-therida, Leaiina and Estheriellina. The two latter are distinct extinct groups and their soft bodies were found recently in several specimens. Leaiina with 1-5 radial carina on the carapace valve ranges from the Devonian to Permian and Estheriellina with 3-16 radial costae on the carapace valve appears in the Triassic to Cretaceous interval.

    Yin et al. have described an innovative filter-less optical millimeter-wave generation scheme for octotupling of a 10 GHz RF oscillator, or sedecimtupling of a 5 GHz RF oscillator using two parallel dual-parallel Mach-Zehnder modulators (DP-MZMs). The great merit of their design is the suppression of all harmonics except those of order ? (octotupling) or all harmonics except those of order ? (sedecimtupling), where ? is an integer. A demerit of their scheme is the requirement to set a precise RF signal modulation index in order to suppress the zeroth order optical carrier. The purpose of this comment is to show that, in the case of the octotupling function, all harmonics may be suppressed except those of order ?, where ? is an odd integer, by the simple addition of an optical ? phase shift between the two DP-MZMs and an adjustment of the RF drive phases. Since the carrier is suppressed in the modified architecture, the octotupling circuit is thereby released of the strict requirement to set the drive level to a precise value without any significant increase in circuit complexity.

    Knowledge management (KM is an important practice in a corporation and an essential issue that academic scholars intend to explore continuously in the era of knowledge economy. However, KM presents a variety of perspectives that are still undefined for many knowledge workers and academic researchers. Many scholars propose a few categories and frameworks about KM, but a static outcome. Social network analysis (SNA is a method to present and measure the interaction among network entities and it is suitable to construct the dynamic relationship networks. The purpose of this study is to acquire the research issues and contexts of KM within information-related graduate schools based on a keyword network analysis. Moreover, we build a dynamic KM research network through these linkages with keywords. The results of this study confirm the essential research perspectives in a KM domain and suggest a variety of KM research ideas which provide the industries, governments, and academic communities with a macro and dynamic KM research viewpoint.

    In a recent article [1] we examined the influence of the applied electron dose rate on the magnitude of the image contrast in high-resolution transmission electron microscopy (HRTEM). We concluded that the magnitude of the image contrast is not substantially affected by the applied electron dose rate. This result is in obvious contradiction to numerous earlier publications by Kisielowski and coworkers [2-7], who commented our recent article due to this contradiction. The present short communication is a response to the comment of Kisielowski and coworkers on our recent article, where we provide additional arguments supporting our initial findings and conclusions on the magnitude of the image contrast in HRTEM.

Based on the CREATER model, this study investigated the teachers’ experiences as change agents in each stage of the process. The research results could provide guidelines for educators who are devoted to promote the information literacy or other innovations. The method of case study was used to design this study. The subjects of this study were the teachers who voluntarily implemented the information literacy curriculum in an elementary school in the southern part of Taiwan. The methods for collecting research data were observations, interviews, and document analyses. The research results showed that the change process of implementing the information literacy curriculum corresponded to the seven stages of the CREATER model. However, the stages of “care,” “relate,” and “examine,” did not obviously happen in sequence. As members of the organization, the teachers could transform effectively the innovative concept into an action, but whether the innovation could be persistent depended on team relationships, teachers’ self-renewal capacity, and approvals and participation of the leaders who really managed the organization.頁次:70-89

    Full Text Available Fantasies of man travelling into space form a main part of the popular movie genre ‘Science Fiction’. These celluloid visions are not only fantasies of improving transport, they also convey a meaning in a figurative sense. They can be seen as a modern adoption of one of humanities oldest metaphors, ‘life as a sea fare voyage’: the meaning, which was once expressed by this ‘nautical metaphor’, has been transferred and can nowadays be found in films, which show astro-nauts crossing the frontier from known space into the unknown space. In order to conclude on their attitude towards technological progress in the early 20th century, the two oldest space travel movies, Le Voyage dans la Lune (F 1902 and Le Voyage a Travers L’Impossible (F 1904 will be analyzed.

    Full Text Available Objective – To survey the current status of Web usability Policies/Standards/Guidelines (PSGs found in academic libraries of the Association of Research Libraries (ARL. Researchers sought to investigate whether PSGs are in place, the levels of difficulty surrounding implementation, the impact of PSGs on design, testing, and resource allocation, and the relationship between ARL ranking and usability practice or PSGs.Design – Survey.Setting – North America.Subjects – Academic libraries of the ARL.Methods – An 18‐question survey consisting of multiple choice, Likert scale, and open‐ended questions was sent to all 113 ARL libraries in November 2007. Survey recipients were selected as the person in charge of Web site usability by visiting library Web sites and phone inquiry. The survey was concluded in January 2008 with a response rate of 74% (84 institutions. The researchers used t‐test to detect any difference in ARL library ranking between libraries with and without PSGs. Pair‐wise t‐tests were conducted to identify gaps in difficulty implementing PSGs. In addition, they used Pearson’s Correlation to investigate any significant correlations between variables such as ARL rank and resource allocation.Main Results – Of the 84 respondents, 34 (40% have general library Web PSGs and 25 (30% have specific usability PSGs; 41 (49% have at least one type of in‐library PSG. Of the 43 (51% libraries that do not have PSGs, 30 (36% are at universities with institutional Web usability PSGs; 26 (87% follow those guidelines. There was no statistically significant relationship between ARL ranking and PSG status (see Table 1. The authors asked about difficulty in implementing PSGs. Of the 32 libraries responding to a question about general library Web PSGs, most had slight or moderate difficulty. Twenty‐three libraries with specific usability PSGs identified difficulty levels; some had no difficulty, but a majority had moderate difficulty. For the 26 libraries using institutional Web usability PSGs, most had no or slight difficulty. Pair‐wise t‐tests showed that library Web usability PSGs were significantly more difficult to implement than university Web usability PSGs. Enforcement/agreement issues were reported as the primary difficulty in implementing in‐library PSGs. Technical issues and ambiguity were obstacles at the institutional level. More than half of the 84 libraries have Web advisory committees and about one third have usability committees or Web usability subcommittees. Several libraries answered that they have none of these committees, but indicated that they have some sort of ad hoc committee or user study group to address usability issues. Of the 84 respondents, 71 (85% have conducted usability testing. Sixty‐two libraries (73.8% rated usability testing as important, very important, or extremely important: the rate given for the importance of usability testing did not correlate with ARL ranking. Cited most often in open ended questioningwere the importance of iterative testing, library wide buy‐in, and staff and resource availability. Main web pages were tested most frequently. Fifty‐three libraries (74.6% tested their lower level pages at least once. OPACs were tested the least often. The amount of testing was impacted neither by the existence of library Web PSGs nor usability PSGs. The top two testing methods were in‐person observation and think aloud protocol.Of the 84 libraries, 24 (28% reported having staff dedicated to Web usability issues; twenty full‐time staff and four part‐time staff. There was a weak association between ARL ranking and hours worked by dedicated staff; no association existed for regular staff who take on Web responsibilities. Fifty‐one (60% of libraries had regular staff whose duties included Web usability; forty‐six full‐time and five part‐time. Training did not correlate to amount of testing methods used. There was a weak link between ALR ranking and availability of resources and, the authors showed, more testing was done as resources increased. In response to a query about future Web usability plans, the focus was on usability testing and site redesign, with only three libraries planning to refine or establish usability PSGs.Conclusion – The authors hypothesized that “web usability PSGs would influence usability practice within libraries and other institutions” (953. The data show that PSGs do not influence practices. The authors conclude that there is no significant relationship between PSGs and testing practices or PSGs and the availability of resources. Likewise, ARL ranking had no effect on the establishment of usability PSGs. Most libraries are conducting usability testing, and there was a weak link between ARL ranking and availability of testing resources. Highlighted in the open‐ended questions is the lack of usability expertise among stakeholders. Workload, inadequate human resources, and lack of organizational cohesion are also cited as barriers to the adoption of Web usability PSGs. The authors speculate that Web professionals likely use their own working knowledge and internalized guidelines without having formal documentation. The authors further speculate that the difficulty related to creating mental models that adequately represent library tasks may hinder the use of formal usability PSGs. Additionally, libraries may not regard the lack of usability PSGs as a liability, especially in light of the lack of government mandates or standards. The authors recommend educational efforts for key players on the value of Web usability, support for hiring dedicated staff, and formal documentation to guide design practice. The authors plan to compare the collected PSGs in an upcoming project. Future research could focus on non‐ARL libraries, the relationship between PSGs and user experience, and Content Management System (CMS usability characteristics.

    Full Text Available Eric Chen, David M Brown, Matthew S Benz, Richard H Fish, Tien P Wong, Rosa Y Kim, James C MajorRetina Consultants of Houston, The Methodist Hospital, Houston, Texas, USAPurpose: While the long-term incidence of hydroxychloroquine (HCQ retinopathy is low, there remains no definitive clinical screening test to recognize HCQ toxicity before ophthalmoscopic fundus changes or visual symptoms. Patients receiving HCQ were evaluated with spectral domain optical coherence tomography (SD OCT to assess the feasibility of identifying HCQ retinopathy at an early stage.Methods: Twenty-five patients referred for the evaluation of hydroxychloroquine toxicity underwent a comprehensive ocular examination, Humphrey visual field (HVF perimetry, time domain OCT, and SD OCT. Some patients with screening abnormalities also underwent further diagnostic testing at the discretion of the treating providers.Results: Five patients were found to have SD OCT findings corresponding to HCQ toxicity and retinal damage as seen by clinical exam and/or HVF perimetry. Two patients with advanced toxicity were found to have significant outer retina disruption in the macula on SD OCT. Three patients with early HCQ toxicity and HVF 10-2 perifoveal defects were found to have loss of the perifoveal photoreceptor inner segment/outer segment (IS/OS junction with intact outer retina directly under the fovea, creating the “flying saucer” sign. While two of these three patients had early ophthalmoscopic fundus changes, one had none.Conclusion: Outer retinal abnormalities including perifoveal photoreceptor IS/OS junction disruption can be identified by SD OCT in early HCQ toxicity, sometimes even before ophthalmoscopic fundus changes are apparent. SD OCT may have a potential complementary role in screening for HCQ retinopathy due to its quick acquisition and because it is more objective than automated perimetry.Keywords: drug toxicity, hydroxychloroquine, photoreceptors, screening test
