Homorosoma horridulum Voss 1958 (Curculionidae: Ceutorhynchinae) was described from Kuatun, China, based on two specimens in the J. Klapperich collection. Since that time it has been uninvestigated for more than half a century, except by Colonnelli (2004), who listed it in his world catalogue of the subfamily. The recent examination of the holotype of H. horridulum revealed that it should be placed in the genus Scleropteroides Colonnelli 1979. In addition, Scleropteroides specimens from Taiwan agree well with the holotype of H. horridulum not only in general appearance but also in male genital structures. Here we transfer Homorosoma horridulum Voss 1958 to the genus Scleropteroides Colonnelli 1979 as Scleropteroides horridulus (Voss 1958) and record the species from Taiwan for the first time. Depositories of specimens examined are abbreviated as follows: CMNC: Canadian Museum of Nature, Ottawa; CWOB: C.W. O'Brien collection, Green Valley, Arizona, USA; EUMJ: Laboratory of Environmental Entomology, Faculty of Agriculture, Ehime University, Matsuyama, Japan; NIAES: National Institute for Agro-Environmental Sciences, Tsukuba, Japan; SMNH: Swedish Museum of Natural History, Stockholm, Sweden; and ZIN: Zoological Institute, Russian Academy of Sciences, St. Petersburg, Russia. Before going further, we wish to express our cordial thanks to R. S. Anderson, François Génier (CMNC), H. Kojima (Tokyo University of Agriculture), M. Sakai (Ehime University), C.W. O'Brien, and B. Viklund (SMNH) for the loan or donation of specimens examined. The first author thanks the late P. Lindskog (SMNH) for the help during his first visit to Stockholm.

Astronaut James S. Voss, Expedition Two flight engineer, works with a series of cables on the EXPRESS Rack in the United State's Destiny laboratory on the International Space Station (ISS). The EXPRESS Rack is a standardized payload rack system that transports, stores, and supports experiments aboard the ISS. EXPRESS stands for EXpedite the PRocessing of Experiments to the Space Station, reflecting the fact that this system was developed specifically to maximize the Station's research capabilities. The EXPRESS Rack system supports science payloads in several disciplines, including biology, chemistry, physics, ecology, and medicine. With the EXPRESS Rack, getting experiments to space has never been easier or more affordable. With its standardized hardware interfaces and streamlined approach, the EXPRESS Rack enables quick, simple integration of multiple payloads aboard the ISS. The system is comprised of elements that remain on the ISS, as well as elements that travel back and forth between the ISS and Earth via the Space Shuttle.

Full Text Available Vos, Faust, Voss: Points of contact between Vos by Anna M. Louw and selected other texts This article explores points of contact between “Vos” by Anna M. Louw and a number of related texts, including the following: the book “Job” from the Christian Bible, “Faust” by Goethe, “Voss” by Patrick White and texts forming part of the Gnostic tradition. The analysis describes similarities and differences, arguing that the implication of the points of contact between the various texts is that Vos suggests that the heritage of the Christian Reformation is not adequate for an understanding of life in South Africa, and it has to be supplemented with perspectives from other traditions.

DK phocomelia phenotype (von Voss-Cherstvoy syndrome) caused by somatic mosaicism for del(13q).

Science.gov (United States)

Bamforth, J S; Lin, C C

1997-12-31

DK phocomelia (von Voss-Cherstvoy syndrome) is a rare condition characterized by radial ray defects, occipital encephalocoele, and urogenital abnormalities. Lubinsky et al. [1994: Am J Med Genet 52:272-278] pointed out similarities between this and the del(13q) syndrome. To date, all reported cases of DK phocomelia have been apparently normal chromosomally. We report on a case of DK phocomelia in which the proposita had normal lymphocyte chromosomes, but was mosaic in fibroblasts for del(13)(q12). Fibroblast chromosomes studies on other cases of DK phocomelia have not been reported: this raises the possibility that some cases of DK phocomelia may be somatic mosaics for del(13)(q12).

Retiring after a distinguished f i career, including 14 years at the Cambridge (Massachusetts) Electron Accelerator and 22 years as Head of the Accelerator Department at the DESY Laboratory in Hamburg (March/April, page 6), Gustav-Adolf Voss was invited to give a 'Personal Perspective of High Energy Accelerators' at the Particle Accelerator Conference in Dallas, Texas, in May, of which we publish an abbreviated version. At the beginning of this year I retired as Head of the Accelerator Department at the Deutsches Elektronen Synchrotron, DESY, in Hamburg, a position I had held for 22 years. An invitation to talk gives me a chance to thank my teachers, colleagues and friends from the 37 years I have been working in the accelerator field. My first teachers were Stanley M. Livingston, Ken Robinson and Tom L. Collins. It is widely known that Livingston built the first working cyclotron as his PhD thesis under Ernest Lawrence. It is also known that Lawrence was inspired with the cyclotron idea by reading Rolf Wideroe's pioneer linear accelerator paper in 1927. Rolf Wideroe, although 93 now, is still full of ideas, which he sometimes tries out on me. Accelerator science does not have a long history. Ken Robinson was the legendary genius who developed most of the theory of electron synchrotrons and storage rings single-handed and in whose unpublished papers, found after his death, the basics of the free electron laser had been developed, a full 10 years ahead of time. Tom Collins was Assistant Director at the Cambridge Electron Accelerator (CEA), my first real workplace. He developed the 'Collins Straight Section' and furthered my technical education. Among my CEA colleagues and friends were also Karl Strauch, John Rees, Ewan Paterson, Herman Winick and Albert Hofmann. When I started in the accelerator field, life was different. The first atomic bomb had been exploded not much more than a decade earlier and the prestige of the nuclear physicist was

2001-01-01

Astronaut James S. Voss, Expedition Two flight engineer, performs an electronics task in the Russian Zvezda Service Module on the International Space Station (ISS). Zvezda is linked to the Russian-built Functional Cargo Block (FGB), or Zarya, the first component of the ISS. Zarya was launched on a Russian Proton rocket prior to the launch of Unity, the first U.S.-built component to the ISS. Zvezda (Russian word for star), the third component of the ISS and the primary Russian contribution to the ISS, was launched by a three-stage Proton rocket on July 12, 2000. Zvezda serves as the cornerstone for early human habitation of the station, providing living quarters, a life support system, electrical power distribution, a data processing system, a flight control system, and a propulsion system. It also provides a communications system that includes remote command capabilities from ground flight controllers. The 42,000-pound module measures 43 feet in length and has a wing span of 98 feet. Similar in layout to the core module of Russia's Mir space station, it contains 3 pressurized compartments and 13 windows that allow ultimate viewing of Earth and space.

The study was conducted in May to April 2000, at Turi and Pakem of Sleman district, Yogyakarta. Samples were randomly taken, 5 plants of each variety were studied their morphological characters such as stem, leaf, flower and fruit. The data collected were then analyzed descriptive comparatively and their relationships were then determined. The result of the study indicate that there were at least 8 varieties of salak at Sleman district, green-, black-, yellow-, manggala-, red-yellow-, golden-, red-, and red-black pondoh. Morphological differences among varieties were markedly different. The closest relationship was found between variety of red-black- and black pondoh, while the farthest relationship among the varieties was manggala pondoh.

Full Text Available http://dx.doi.org/10.5007/2175-8026.2016v69n2p107 A number of the dialogues in Patrick White’s Voss (1957, especially those involving Laura Trevelyan, involve an implicit debate about what is meant by country and what it means to live in a country. Is the colony of New South Wales simply a province of the British Empire, a little piece of Britain transplanted on the other side of the world, or is it a place where British settlers will have to adapt their ways and gradually be transformed into something new? In these dialogues, each speaker makes use of words such as country, colony, property and land in order to express their vision of the place where they find themselves, frequently forcing a shift of meaning from one sentence to the next. This study examines how this debate is carried out in the novel and how it functions in Paulo Henriques Britto’s 1985 Brazilian translation.

Putting leaders on the couch. A conversation with Manfred F. R. Kets de Vries. Interview by Diane L. Coutu.

Science.gov (United States)

Kets de Vries, Manfred F

2004-01-01

Much of the business literature on leadership starts with the assumption that leaders are rational beings. But irrationality is integral to human nature, and inner conflict often contributes to the drive to succeed. Although a number of business scholars have explored the psychology of executives, Manfred F.R Kets de Vries has made the analysis of CEOs his life's work. In this article, Kets de Vries, a psychoanalyst, author, and instead professor, draws on three decades of study to describe the psychological profile of successful CEOs. He explores senior executives' vulnerabilities, which are often intensified by followers' attempts to manipulate their leaders. Leaders, he says, have an uncanny ability to awaken transferential processes--in which people transfer the dynamics of past relationships onto present interactions--among their employees and even in themselves. These processes can present themselves in a number of ways, sometimes negatively. What's more, many top executives, being middle-aged, suffer from depression. Mid-life prompts a reappraisal of career identity, and by the time a leader is a CEO, an existential crisis is often imminent. This can happen with anyone, but the probability is higher with CEOs, and senior executives because so many have devoted themselves exclusively to work. Not all CEOs are psychologically unhealthy, of course. Healthy leaders are talented in self-observation and self-analysis, Kets de Vries says. The best are highly motivated to spend time on self-reflection. Their lives are in balance, they can play, they are creative and inventive, and they have the capacity to be nonconformist. "Those who accept the madness in themselves may be the healthiest leaders of all," he concludes.

Two new dicyemid species are described from the endemic cephalopod Octopus maya Voss & Solis-Ramirez collected off Yucatan, Mexico. The renal sacs of 40 juvenile and adult octopuses from four localities were examined. Dicyema hochbergi n. sp. is a medium-sized species that reaches 2,245 µm in length. The vermiform stages consist of 18-24 peripheral cells, a conical calotte and the extension of the axial cell between the base and middle of the metapolar cells. Infusoriform embryos consist of 39 cells with urn cell containing one germinal cell, two nuclei and solid refringent bodies. Dicyema mexcayae n. sp. is a relatively small species that reaches 1,114 µm in length. The vermiform stages are constituted by 14-16 peripheral cells, an elongate calotte and the axial cell extending forward to the middle of the metapolar cells. The infusoriform embryos consist of 37 cells, two solid refringent bodies and urn cells with two nuclei each. The present study represents the first description of a dicyemid species from O. maya and increases the number of described species from Mexican waters to 11.

Variation in physiological response during autumn acclimation was investigated in somatic seedlings of 10 interior spruce (Picea glauca (Moench) Voss x P. engelmannii Parry ex Engelm.) clones from five full-sib families. Experiments were conducted on 2-yr-old seedlings through simulation in a growth chamber. Throughout the experimental period, gas-exchange parameters (net photosynthesis, stomatal conductance to water vapour and instantaneous water-use efficiency) were measured weekly and freezing tolerance was determined five times. Results showed that as seedlings acclimated to decreasing air temperature and photoperiod, stomatal conductance decreased linearly, photosynthesis was unchanged until air temperature and photoperiod were below 10 deg C and 11 h, respectively, water-use efficiency nearly doubled and freezing tolerance increased in a curvilinear fashion. There was significant between- and within-family clonal variation in all of these physiological parameters. 47 refs, 7 figs

Variation in Wood Quality in White Spruce (Picea Glauca (Moench Voss. Part I. Defining the Juvenile–Mature Wood Transition Based on Tracheid Length

Directory of Open Access Journals (Sweden)

Cyriac Serge Mvolo

2015-01-01

Full Text Available Estimations of transition age (TA and juvenile wood proportion (JWP are important for wood industries due to their impact on end-product quality. However, the relationships between analytical determination of TA based on tracheid length (TL and recognized thresholds for adequate end products have not yet been established. In this study, we used three different statistical models to estimate TA in white spruce (Picea glauca (Moench Voss based on TL radial variation. We compared the results with technological maturity. A two-millimeter threshold, previously suggested for good paper tear strength, was used. Tracheid length increased from pith to bark and from breast height to upper height. Juvenile wood (JW was conical with the three models. At breast height, TA ranged from 11 to 27 years and JWP ranged from 15.3% to 47.5% across the three models. The linear mixed model produced more conservative estimates than the maximum-quadratic-linear (M_Q_L model. Both the linear mixed model and the M_Q_L model produced more conservative TA estimates than the piecewise model. TA estimates by the MIXED model, and to a lesser extent by the M_Q_L model, were equivalent to those for real mature wood, whereas TA estimates by the piecewise model were considerably lower, falling into the transition wood area.

This study aimed to determine the diuretic effect of the seed extract combination and its effective dose combination as diuretics. The extract was prepared by maceration method using ethanol 96%. Diuretic activity test was divided into 5 treatment groups. Each group consisted of 5 rats. Group 1 (negative control was given suspension of Na-CMC 0.5%; Group 2 (positive control was given furosemide 3.6 mg/kgBW; Group 3, 4, and 5 were given dose combination of snake fruit seed extract and papaya seed extract successively at “37.5 mg/kgBW + 7.5 mg/kgBW”; “70 mg/kgBW + 15mg/kgBW”; and “140 mg/kgBW + 30 mg/kgBW”. Each rat was then orally given warm distilled water (70°C 10ml/100gBW as loading dose. The excreted urine volume was measured and recorded every 30 minutes for 6 hours which was continued to cumulative urine volume calculation. Furthermore, sample was taken from the cumulative urine to measure levels of sodium (Na, potassium (K, and the pH of the urine. Data were statistically analyzed using ANOVA (Analysis of Variance. The results showed that the effective extract dose combination was found in Group 5’s dose (140 mg/kgBW of snake fruit seed extract and 30 mg/kgBW papaya seed extract with diuretic activity index of 1.48; urine pH of 7.52; sodium saluretic index of 1.62; and potassium saluretik index of 1.56

Full Text Available This paper will examine an anonymous ‘planh’, “Totas honor e tuig faig benestan”, for the death of Manfred of Swabia, illegitimate son of Frederick II, who was killed in the battle of Benevento in 1266. The text is copied in a section of the ‘twin’ chansonniers I and K which contains mainly lyric laments (an exception in the troubadour manuscript tradition and for this reason will serve as a basis for a discussion of the concept of ‘documentary series’. The paper will also consider the author’s origin, probably Italian on the basis of the linguistic and metrical evidence, and attempt to place the planh more precisely within the context of the struggle between Charles of Anjou and Manfred, as well as illustrate the role played by political troubadour poetry at the Italian court of the last Swabians.

Full Text Available Der Beitrag von Manfred Becker lässt sich wohlmeinend als Plädoyer für einen pragmatischen Umgang mit dem AGG lesen. Er möchte Personaler/-innen zeigen, wie die Vorgaben des AGG im Rahmen eines Human Resources Diversity Managements positiv umgesetzt werden können. In weiten Teilen überzeugen die Ausführungen des Autors aber nicht. Gerade die Darstellung der Inhalte des AGG ist stark von seiner skeptischen Grundhaltung gegenüber dessen Zielsetzung geprägt. Auch wenn die Ausführungen zu konkreten Betriebs- und Personalmaßnahmen gelungener sind, stellt dieser Beitrag insgesamt kein überzeugendes und lesenswertes Werk dar.With the best intention, the work by Manfred Becker can be read as a plea for a pragmatic approach to the AGG. He wishes to show personnel how the guidelines of the AGG can be put into practice within the framework of Human Resources Diversity Management. However, the author’s work is often unconvincing. In particular, the presentation of the contents of the AGG is strongly influenced by his skeptical attitude toward its goals. Even when his approach to concrete company and personnel measures is more successful, the book is neither convincing nor a worthwhile read.

The importance of Scanning Tunneling Microscopy (STM) in today's research and industry leads to the question of how to include such a key technology in physics education. Manfred Euler has developed an acoustic model experiment to illustrate the fundamental measuring principles based on an analogy between quantum mechanics and acoustics. Based on earlier work we applied mobile devices such as smartphones and tablets instead of using a computer to record and display the experimental data and thus converted Euler's experimental setup into a low-cost experiment that is easy to build and handle by students themselves.

Emily and Charlotte Brontë’s Re-reading of the Byronic hero La réécriture du héros byronien par Emily et Charlotte Brontë

Directory of Open Access Journals (Sweden)

Cristina Ceron

2010-03-01

Full Text Available The widespread popularity of Byron’s work during the Victorian age introduced several subversive possibilities for reading his characters as icons of transgression and insights into the literary tabooed. For Victorian novelists, one of the most intriguing aspects of his works was his obsessive explorations of literal or symbolic sibling incest, as the possibility that desire arises from an identification between male and female versions of the same psyche. Emily Brontë’s reading of Byron privileges this dark side of the literary myth, and her main focus is on the mysterious identity and Gothic aspects of the Byronic hero. Even though several critics have actually labelled the character of Heathcliff as ‘Byronic hero’, the debate has not delved into the textual or thematic evidence of the relation between Brontë’s protagonist and Byron hypertexts. My paper aims at investigating Brontë’s reading of Byron’s works, in particular her indebtedness to Manfred and to the relationship between Manfred and Astarte for the creation of the morbid passion experienced by  Heathcliff and Catherine. The study will concentrate on Brontë’s appropriation and emphasis on the Gothic elements presented in nuce in Manfred, such as the spectral nature of Astarte, or the supernatural aspects of Manfred’s nature, whose will supersedes even Fate. My hypothesis is that Brontë makes use of these aspects of Byron’s characters with the precise aim of setting the Gothic element as alternative narrative mode, as the subversive element inside a realistic novel. On the contrary, in spite of some juvenile experiments on the gothic, Charlotte’s reading of the Byronic hero is much more framed within the conventions of the realistic novel, and in the second section of my essay I maintain that what comes to the fore in Jane Eyre is the unsurpassed mastery the novelist shows in the combination of the realistic plot with the gothic elements and features of the

Microjets and coated wheels: versatile tools for exploring collisions and reactions at gas-liquid interfaces.

Science.gov (United States)

Faust, Jennifer A; Nathanson, Gilbert M

2016-07-07

This tutorial review describes experimental aspects of two techniques for investigating collisions and reactions at the surfaces of liquids in vacuum. These gas-liquid scattering experiments provide insights into the dynamics of interfacial processes while minimizing interference from vapor-phase collisions. We begin with a historical survey and then compare attributes of the microjet and coated-wheel techniques, developed by Manfred Faubel and John Fenn, respectively, for studies of high- and low-vapor pressure liquids in vacuum. Our objective is to highlight the strengths and shortcomings of each technique and summarize lessons we have learned in using them for scattering and evaporation experiments. We conclude by describing recent microjet studies of energy transfer between O2 and liquid hydrocarbons, HCl dissociation in salty water, and super-Maxwellian helium evaporation.

World War I advanced the development of aviation from the concept of flight to the use of aircraft on the battlefield. Fighter planes advanced technologically as the war progressed. Fighter pilot aces Francesco Baracca and Manfred von Richthofen (the Red Baron) were two of the most famous pilots of this time period. These courageous fighter aces skillfully maneuvered their SPAD and Albatros planes, respectively, while battling enemies and scoring aerial victories that contributed to the course of the war. The media thrilled the public with their depictions of the heroic feats of fighter pilots such as Baracca and the Red Baron. Despite their aerial prowess, both pilots would eventually be shot down in combat. Although the accounts of their deaths are debated, it is undeniable that both were victims of traumatic head injury.

Life is physics and chemistry and communication.

Science.gov (United States)

Witzany, Guenther

2015-04-01

Manfred Eigen extended Erwin Schroedinger's concept of "life is physics and chemistry" through the introduction of information theory and cybernetic systems theory into "life is physics and chemistry and information." Based on this assumption, Eigen developed the concepts of quasispecies and hypercycles, which have been dominant in molecular biology and virology ever since. He insisted that the genetic code is not just used metaphorically: it represents a real natural language. However, the basics of scientific knowledge changed dramatically within the second half of the 20th century. Unfortunately, Eigen ignored the results of the philosophy of science discourse on essential features of natural languages and codes: a natural language or code emerges from populations of living agents that communicate. This contribution will look at some of the highlights of this historical development and the results relevant for biological theories about life. © 2014 New York Academy of Sciences.

Special offer for CERN personnel CERN personnel and their spouses have until Tuesday, 18 March 2008 to buy tickets for « Vie de Galilée » ("Life of Galileo") at the Théâtre de Carouge at the special discount rate of 28 CHF (instead of 35 CHF). This play, by the German dramatist Bertolt Brecht, is directed by Manfred Karge and recounts the life of the father of modern physics in fifteen tableaux. The wily, impassioned teacher Galileo is about to substantiate Copernicus’ theory that the Earth is not a static object but revolves around the sun, a discovery that revolutionised mankind’s view of itself and the world. When hauled before the Inquisition, he recants.

Investigation of the sustainability of nuclear power use

International Nuclear Information System (INIS)

Gottschalk-Mazouz, N.; Hubig, C.; Mazous, N.

2001-01-01

The report reviews the sustainability discussion, specifically for the energy sector. Definitions, rules and indicators are gone into. Publications speaking against nuclear power are analysed: Brundtland, UBA, SRU, UNCSD, HGF. The main section analyzed positive publications, i.e. Voss, Kessler, and the NEA study. 11 central argumentation strategies are identified and analyzed. They are shown to be faulty, based on selective argumentations which omit either important comparative arguments relevant to the whole energy sector, or alternative options, or additional risks caused by changes in boundary conditions. Further, aspects of human and social acceptability are left out of account as well as problems of institutionalisation. (orig.) [de

Full Text Available Halimodendron halodendron has been used as forage in northwestern China for a long time. Its young leaves and flowers are edible and favored by indigenous people. In this study, eleven phenolic compounds were bioassay-guided and isolated from the aerial parts of H. halodendron for the first time. They were identified by means of physicochemical and spectrometric analysis as quercetin (1, 3,5,7,8,4'-pentahydroxy-3'-methoxy flavone (2, 3-O-methylquercetin (3, 3,3'-di-O-methylquercetin (4, 3,3'-di-O-methylquercetin-7-O-β-D-glucopyranoside (5, isorhamentin-3-O-β-D-rutinoside (6, 8-O-methylretusin (7, 8-O-methylretusin-7-O-β-D-glucopyranoside (8, salicylic acid (9, p-hydroxybenzoic acid (ferulic acid (10, and 4-hydroxy-3-methoxy cinnamic acid (11. They were sorted as flavonols (1–6, soflavones (7 and 8, and phenolic acids (9–11. Among the compounds, flanools 1–4 revealed a strong antibacterial activity with minimum inhibitory concentration (MIC values of 50–150 μg/mL, and median inhibitory concentration (IC50 values of 26.8–125.1 μg/mL. The two isoflavones (7 and 8 showed moderate inhibitory activity on the test bacteria. Three phenolic acids (9, 10 and 11 showed strong antibacterial activity with IC50 values of 28.1–149.7 μg/mL. Antifungal activities of the compounds were similar to their antibacterial activities. All these phenolic compounds showed significant antimicrobial activity with a broad spectrum as well as antioxidant activity based on 1,1-diphenyl-2-picrylhydrazyl (DPPH radical scavenging and β-carotene-linoleic acid bleaching assays. In general, the flavonol aglycones with relatively low polarity exhibited stronger activities than the glycosides. The results suggest the potential of this plant as a source of functional food ingredients and provide support data for its utilization as forage as well.

2007-01-01

In the 1970s, Richard Voss and John Clarke researched the actual audio physical sound of music. There are three types of noise: white noise, 1/f noise, and Brownian motion noise (1/f 2 ). 1/f noise is found to be most pleasing to human ears. White noise is too random and Brownian noise is too correlated. Similarly, for 2-dimensional sources such as graphics and images, three characteristics of monotonous, harmony and muss are also observed. The 1/f fluctuation theory provides a good way to generate affective signals both for 1-dimensional and 2-dimensional signals. This paper provides an algorithm which can generate affective patterns or graphics and obey the criteria of affective information processing

Solving Large Scale Nonlinear Eigenvalue Problem in Next-Generation Accelerator Design

2006-09-28

A number of numerical methods, including inverse iteration, method of successive linear problem and nonlinear Arnoldi algorithm, are studied in this paper to solve a large scale nonlinear eigenvalue problem arising from finite element analysis of resonant frequencies and external Q{sub e} values of a waveguide loaded cavity in the next-generation accelerator design. They present a nonlinear Rayleigh-Ritz iterative projection algorithm, NRRIT in short and demonstrate that it is the most promising approach for a model scale cavity design. The NRRIT algorithm is an extension of the nonlinear Arnoldi algorithm due to Voss. Computational challenges of solving such a nonlinear eigenvalue problem for a full scale cavity design are outlined.

1986-01-01

Manfred Eigen, Premio Nobel per la chimica nel 1967, e la sua collaboratrice Ruthild Winkler hanno voluto con questo libro uscire allo scoperto, esponendo in una trattazione complessa ma comprensibile per ogni lettore veramente interessato una teoria molto audace, basata su ricerche e scoperte di Eigen stesso e di altri (come per esempio Thom e Prigogine) che in questi ultimi anni sono al centro dell’attenzione degli scienziati, anche se non sempre sono filtrate al di fuori della loro cerchia. Questa teoria ha come perno la nozione di gioco: e non già in una o più delle innumerevoli accezioni della parola, ma in tutte, con l’aggiunta di una ulteriore accezione che sottende tutte le altre: il gioco come struttura intelligibile emergente dal divenire caotico, quindi come fenomeno «che ha guidato fin dall’inizio il corso dell’Universo». Gioco, in questo libro, è dunque un «fenomeno naturale», non specificamente umano. I giochi che noi tutti giochiamo sono soltanto la schiuma variegata di un flutto...

The HERA project (HERA 1981, Wiik 1982, 1992, Voss 1988) was approved in 1984. Operation of HERA for physics started in 1992 with the two large general purpose detectors H1 (1986) and ZEUS (1986) taking data. A third experiment, HERMES (1990), which has been approved recently for the measurement of the nucleon spin structure by colliding the polarized electron beam with a gas jet of polarized nucleons, is under construction. A fourth experiment, HERA-B (HERA-B 1992), which aims at measuring CP violation in the b anti b system by scattering beam protons on a fixed target, is under discussion. These lectures are intended for the newcomer to the field and focus on results obtained by H1 and ZEUS. (orig.)

2012-07-01

Due to a violent earthquake and the resulting tsunami, a core melt down resulted at the nuclear power plant Fukushima Daiichi in Japan. Thus, at 30th June, 2011, the Federal Government decided to complete the utilization of the nuclear power in Germany. Is this the end of the atomic age? Under this aspect, the booklet under consideration consists of the following nine contributions: (1) Why is the ''energy policy turnaround'' a social question? (Harald Welzer); (2) Tsunami in the living room: Catastrophes facilitated by the media (Joerg R. Bergmann); (3) Learning from the catastrophe (Manfred Buerger); (4) Perspectives of the nuclear power in Europe and globally (Lutz Mez); (5) Outsider or leader? The 'model Germany' and the European energy policy (Severin Fischer); (6) 'Energy policy turnaround': Quo vadis?

CERN Library - Journal cancellations in 2008

CERN Multimedia

2007-01-01

In 2007, the CERN Library has been allocated a smaller budget than in 2006. Since subscriptions must be paid in advance, the current budget is being used to pay the journal collection for the year 2008 and is unfortunately not sufficient to maintain the information resources at the 2007 level. Consequently, the Working Group for Acquisitions (WGA) was obliged to identify candidates for cancellation for 2008. The list of candidates is shown here. As in the past, readers will be able to order articles from journals not available in the CERN Library through the Interlibrary Loan (ILL) service; generally articles are sent within 24h. Library users are invited to send comments on this proposal not later than 4 August 2007 to the WGA Chairman, Rudiger Voss, with a copy to the Head Librarian, Jens Vigen.

Determining baselines and variability of elements in plants and soils near the Kenai National Wildlife Refuge, Alaska

Science.gov (United States)

Crock, J.G.; Severson, R.C.; Gough, L.P.

1992-01-01

Recent investigations on the Kenai Peninsula had two major objectives: (1) to establish elemental baseline concentrations ranges for native vegetation and soils; and, (2) to determine the sampling density required for preparing stable regional geochemical maps for various elements in native plants and soils. These objectives were accomplished using an unbalanced, nested analysis-of-variance (ANOVA) barbell sampling design. Hylocomium splendens (Hedw.) BSG (feather moss, whole plant), Picea glauca (Moench) Voss (white spruce, twigs and needles), and soil horizons (02 and C) were collected and analyzed for major and trace total element concentrations. Using geometric means and geometric deviations, expected baseline ranges for elements were calculated. Results of the ANOVA show that intensive soil or plant sampling is needed to reliably map the geochemistry of the area, due to large local variability. For example, producing reliable element maps of feather moss using a 50 km cell (at 95% probability) would require sampling densities of from 4 samples per cell for Al, Co, Fe, La, Li, and V, to more than 15 samples per cell for Cu, Pb, Se, and Zn.Recent investigations on the Kenai Peninsula had two major objectives: (1) to establish elemental baseline concentrations ranges for native vegetation and soils; and, (2) to determine the sampling density required for preparing stable regional geochemical maps for various elements in native plants and soils.

Dave Walker, Pilot Ken Cockrell, and Mission Specialists Jim Voss, Jim Newman, and Mike Gernhardt, began their sixth day in orbit by monitoring the free orbiting Wake Shield Facility (WSF). Later Cmdr. Walker conducted an interview with television reporters from Atlanta and Boston, answering questions about the mission and general questions about NASA's space program. The crew filmed a video fo themselves performing daily routines (eating, shaving, exercising), as well as some of the physiological experiments, and shuttle equipment maintenance and checkout. One of the secondary experiments included the Commercial Generic Bioprocessing Apparatus-7 (CGBA-7), which served as an incubator and experiment station for a variety of tests (agricultural, pharmaceutical, biomedical, and environmental). Earth views included some cloud cover, the Gulf of Mexico, Texas, and the Atlantic Ocean.

Collinear wake field acceleration

International Nuclear Information System (INIS)

Bane, K.L.F.; Chen, P.; Wilson, P.B.

1985-04-01

In the Voss-Weiland scheme of wake field acceleration a high current, ring-shaped driving bunch is used to accelerate a low current beam following along on axis. In such a structure, the transformer ratio, i.e., the ratio of maximum voltage that can be gained by the on-axis beam and the voltage lost by the driving beam, can be large. In contrast, it has been observed that for an arrangement in which driving and driven bunches follow the same path, and where the current distribution of both bunches is gaussian, the transformer ratio is not normally greater than two. This paper explores some of the possibilities and limitations of a collinear acceleration scheme. In addition to its application to wake field acceleration in structures, this study is also of interest for the understanding of the plasma wake field accelerator. 11 refs., 4 figs

Full Text Available This study was carried out based on a experience of reflective educational intervention in La Cruz and Bello Oriente (Manrique neighbourhood, a marginal sector of the northeastern part of the Commune 3 in Medellin city, Colombia, where psychosocial problems arise because of life conditions such as limited educational opportunities and employment, domestic violence, illegal armed forces, sexual abuse, social discrimination and lack of adequate public services, among others, all risk factors for drug dependence. We used a structured interview designed to identify habits in the use of free and lesure time, and field notes, instruments that allowed an analysis by triangulation of the observation process. The organization and interpretation of data analysis were conducted in the framework of the theory of Human Scale Development of Manfred Max-Neef, a playful approach to the psycho-pedagogic method in order to analyze its effects as an influence on the satisfaction of human needs. The findings show the need for another educational model that promotes creativity, solidarity, fun, and integration generates enthusiasm and motivational attitudes of young people subjected to extreme stressors, and promotes mental, physical and social development to prevent drug dependence and promote a social process of transformation in these neighborhoods.

Pragmatic turn in biology: From biological molecules to genetic content operators.

Science.gov (United States)

Witzany, Guenther

2014-08-26

Erwin Schrödinger's question "What is life?" received the answer for decades of "physics + chemistry". The concepts of Alain Turing and John von Neumann introduced a third term: "information". This led to the understanding of nucleic acid sequences as a natural code. Manfred Eigen adapted the concept of Hammings "sequence space". Similar to Hilbert space, in which every ontological entity could be defined by an unequivocal point in a mathematical axiomatic system, in the abstract "sequence space" concept each point represents a unique syntactic structure and the value of their separation represents their dissimilarity. In this concept molecular features of the genetic code evolve by means of self-organisation of matter. Biological selection determines the fittest types among varieties of replication errors of quasi-species. The quasi-species concept dominated evolution theory for many decades. In contrast to this, recent empirical data on the evolution of DNA and its forerunners, the RNA-world and viruses indicate cooperative agent-based interactions. Group behaviour of quasi-species consortia constitute de novo and arrange available genetic content for adaptational purposes within real-life contexts that determine epigenetic markings. This review focuses on some fundamental changes in biology, discarding its traditional status as a subdiscipline of physics and chemistry.

Picture taken by Rudiger Voss in the Legal Service LibraryJean-Marie Dufour, CERN Legal Advisor from 1974 until his retirement in 2001, passed away on 8 July. For us, his colleagues in the Legal Service, Jean-Marie was a tutor and a reference, who passed on to us his passion for the practice of law in an intergovernmental organisation. As a boss, his abiding managerial quality was his unstinting loyalty to his collaborators. Jean-Marie joined CERN in 1966 and for the next 35 years was to be the guardian of the Laboratory’s rules. This was his view of the Organization: "...I have discovered [at CERN] a fascinating universe driven by two forces: science and Europe; a world of physicists and engineers who, encouraged by the States of Europe, run a remarkable Laboratory, where Europeans have achieved reconciliation and restored the grand tradition of European physics, attracting physicists from around the world; a Laboratory that transcends not only the fro...

Anticipatory synchronization via low-dimensional filters

International Nuclear Information System (INIS)

Pyragiene, T.; Pyragas, K.

2017-01-01

An anticipatory chaotic synchronization scheme based on a low-order all-pass filter is proposed. The filter is designed as a Padé approximation to the transfer function of an ideal delay line, which is used in a standard Voss scheme. We show that despite its simplicity, the filter works in an anticipatory scheme as well as an ideal delay line. It provides extremely small synchronization error in the whole interval of anticipation time where the anticipatory manifold is stable. The efficacy of our scheme is explained by an analytically solvable model of unidirectionally coupled unstable spirals and confirmed numerically by an example of unidirectionally coupled chaotic Rössler systems. - Highlights: • A new coupling scheme for anticipating chaotic synchronization is proposed. • The scheme consists of a drive system coupled to a low-dimensional filter. • Long-term anticipation is achieved without using time-delay terms. • An analytical treatment estimates the maximum anticipation time. • The method is verified for the Rössler system.

Three cultivars of snake fruits, Pondoh Hitam, Pondoh Super, and Gading, were freshly extracted using liquid-liquid extraction. The aroma compounds of the three samples were analyzed by GC-MS and GC-olfactometry using the nasal impact frequency (NIF) method. A total of 24 odor-active compounds were associated with the aroma of snake fruit. Methyl 3-methylpentanoate was regarded as the character impact odorant of typical snake fruit aroma. 2-Methylbutanoic acid, 3-methylpentanoic acid, and an unknown odorant with very high intensity were found to be responsible for the snake fruit's sweaty odor. Other odorants including methyl 3-methyl-2-butenoate (overripe fruity, ethereal), methyl 3-methyl-2-pentenoate (ethereal, strong green, woody), and 2,5-dimethyl-4-hydroxy-3[2]-furanone (caramel, sweet, cotton candy-like) contribute to the overall aroma of snake fruit. Methyl dihydrojasmonate and isoeugenol, which also have odor impact, were identified for the first time as snake fruit volatiles. The main differences between the aroma of Pondoh and Gading cultivars could be attributed to the olfactory attributes (metallic, chemical, rubbery, strong green, and woody), which were perceived by most of the panelists in the Pondoh samples but were not detected in the Gading samples. This work is a prerequisite for effective selection of salak genotypes with optimal aroma profiles for high consumer acceptance.

PAULO FREIRE Y LA CONDICIÓN DE LA MUJER Resumen: De naturaleza bibliográfica, el ensayo tiene como objetivo (revisitar el tema de la condición de la mujer en la obra de Freire. El autor denuncia toda forma de discriminación. La de la mujer, más explícitamente en Pedagogía de la Esperanza, A la sombra de esta manguera, Pedagogía de la Indignación y Pedagogía de los sueños posibles. Sobre Pedagogía del Oprimido, declaró que jamás habría escrito el libro si permitiese oprimir a sus hijas, a su mujer o a las mujeres con las que trabajaba. Pero aceptó las críticas de las feministas estadounidenses de que el lenguaje de aquel libro sería machista. Por otro lado, un amplio movimiento feminista en Suiza se inspiró en aquella obra para su lucha, sin ver en ella lenguaje machista. Según el gran lingüista Manfred Peters, el cambio del lenguaje machista se debe inserirse en un proceso de transformación social, sin el cual tan sólo alteraciones del lenguaje no resolverían el problema. Palabras-clave: Mujeres. Machismo. Feminismo. Freire. Discriminación.

Could a revision of the current guidelines for cancer drug use improve the quality of cancer treatment?

Full Text Available Theodor H Lippert,1 Hans-Jörg Ruoff,1 Manfred Volm2 1Medical Faculty, University of Tübingen, Tübingen, Germany; 2Medical Faculty, University of Heidelberg, Heidelberg, Germany Abstract: Clinical practice guidelines are indispensable for such a variable disease as malignant solid tumors, with the complex possibilities of drug treatment. The current guidelines may be criticized on several points, however. First, there is a lack of information on the outcome of treatment, such as the expected success and failure rates. Treating not only drug responders but also nonresponders, that is, patients with drug resistance, must result in failures. There is no mention of the possibility of excluding the drug nonresponders, identifiable by special laboratory tests and no consideration is given to the different side effects of the recommended drug regimens. Nor are there any instructions concerning tumor cases for which anticancer drug treatment is futile. In such cases, early palliative care may lead to significant improvements in both life quality and life expectancy. Not least, there is no transparency concerning the preparation of the guidelines: persons cannot be identified who could give a statement of conflicts of interest, and responsibility is assumed only by anonymous medical associations. A revision of the current guidelines could considerably improve cancer treatment. Keywords: anticancer drugs, quality of guidelines, critical remarks

Hi-tech in space - Rosetta - a space sophisticate

The European Space Agency’s Rosetta mission will be getting under way in February 2004. The Rosetta spacecraft will be pairing up with Comet 67P/Churyumov-Gerasimenko and accompanying it on its journey, investigating the comet’s composition and the dynamic processes at work as it flies sunwards. The spacecraft will even deposit a lander on the comet. “This will be our first direct contact with the surface of a comet,” said Dr Manfred Warhaut, Operations Manager for the Rosetta mission at ESA's European Space Operations Centre (ESOC) in Darmstadt, Germany. The trip is certainly not short: Rosetta will need ten years just to reach the comet. This places extreme demands on its hardware; when the probe meets up with the comet, all instruments must be fully operational, especially since it will have been in “hibernation” for 2 and a half years of its journey. During this ‘big sleep’, all systems, scientific instruments included, are turned off. Only the on-board computer remains active. Twelve cubic metres of technical wizardry Rosetta’s hardware fits into a sort of aluminium box measuring just 12 cubic metres. The scientific payload is mounted in the upper part, while the subsystems - on-board computer, transmitter and propulsion system - are housed below. The lander is fixed to the opposite side of the probe from the steerable antenna. As the spacecraft orbits the comet, the scientific instruments will at all times be pointed towards its surface; the antenna and solar panels will point towards the Earth and Sun respectively. For trajectory and attitude control and for the major braking manœuvres, Rosetta is equipped with 24 thrusters each delivering 10 N. That corresponds to the force needed here on Earth to hold a bag containing 10 apples. Rosetta sets off with 1650 kg of propellant on board, accounting for more than half its mass at lift-off. Just 20% of total mass is available for scientific purposes. So when developing the research instruments

NTDs associated with these syndromes, disorders and maternal risk factors are a rare but important cause of NTDs. The recurrence risk and the preventive effect of maternal folic acid intake in NTDs associated with syndromes, disorders and maternal risk factors may be different from those of nonsyndromic multifactorial NTDs. Perinatal diagnosis of NTDs should alert doctors to the syndromes, disorders and maternal risk factors associated with NTDs, and prompt thorough etiologic investigation and genetic counseling.

Full Text Available Climatic sensitivity of white spruce (Picea glauca (Moench Voss was examined growing in association with trembling aspen (Populus tremuloides Michx. at their southern limit of distribution in a transitional ecotone between the southern boreal forest and northern prairie region. The study was carried out in the Spruce Woods Provincial Park (SWPP located in southwestern Manitoba, Canada. The dry regional climate restricted trembling aspen growth during the growing season via moisture deficiency and temperature induced drought stress. Warm, mild winters also negatively affected radial growth of trembling aspen. Growth of white spruce was moderated by conditions within the aspen stands as radial growth patterns showed low variability from year to year, a low common growth signal, and a stronger response to temperature than to precipitation. Nonetheless, the dry regional climate still restricted growth of white spruce during the growing season via temperature induced drought stress. The findings of the study for white spruce support the stress gradient hypothesis in which facilitative interactions between tree species are expected under harsher environmental conditions.

CERN Library - Reduction of subscriptions to scientific journals

CERN Multimedia

2005-01-01

The Library Working Group for Acquisitions has identified some scientific journal subscriptions as candidates for cancellation. Although the 2005 budget is unchanged with respect to 2004 thanks to the efforts of the Management, it does not take account of inflation, which for many years has been much higher for scientific literature than the normal cost-of-living index. For 2006, the inflation rate is estimated to be 7-8%. Moreover, the Library does not only intend to compensate for the loss of purchasing power but also to make available some funds to promote new Open Access publishing models. (See Bulletin No.15/2005) The list of candidates can be found on the Library homepage (http://library.cern.ch/). In addition, some subscriptions will be converted to online-only, i.e. CERN will no longer order the print version of certain journals. We invite users to carefully check the list (http://library.cern.ch/). Comments on this proposal should be sent to the WGA Chairman, Rudiger Voss, with a copy to the Hea...

Full Text Available This paper considers the knowledge, resource, and competence management practices of a capital intensive company in Brazil. We map general and essential competencies, identify critical performance factors and catalogue the knowledge management tools available to the firm. We also attempt to trace the impact of the implementation strategies selected on the success or failure of the project. Two specific questions that arose in the course of the research were: a. How can firms maintain the knowledge base of the organization in the presence of high turnover, and b. What are the effects of the loss of intellectual capital on the firm. This was exploratory research, using the longitudinal case study method advocated by Voss, Tsikritsis and Frolich. The unit of analysis was the individual project. We studied 15 new plant erections or revamps carried out between 2007 and 2009. Data sources included interviews with key project management employees as well as analyses of management reports, firm data banks, and software used in the project management process. Among other things, our research identified a strong relationship between the profile of the individual project manager and the management structure adopted on a given project.

Do Offspring of Insects Feeding on Defoliation-Resistant Trees Have Better Biological Performance When Exposed to Nutritionally-Imbalanced Food?

Full Text Available White spruce (Picea glauca (Moench Voss trees that are resistant or susceptible to spruce budworm (Choristoneura fumiferana (Clem. attack were identified in a southern Quebec plantation. Due to high mortality-induced selective pressures imposed by resistant trees on spruce budworm larvae, insects that survive on resistant trees exhibited greater biological performance than those on susceptible trees. We tested the hypothesis that this better biological performance is maintained across generations when progeny were subjected to nutritional stress. We collected pupae from resistant and susceptible trees (phenotype. Adults were reared under controlled laboratory conditions. Progeny were subsequently reared on two types of artificial diet (high vs. low quality. Low quality diet simulated food quality deterioration during outbreak conditions. Results confirmed that surviving insects collected from resistant trees have better performance than those from susceptible trees. Offspring performance (pupal mass, developmental time was affected only by diet quality. These results suggest that adaptive advantages that would be acquired from parents fed on resistant trees are lost when progeny are exposed to nutritionally-imbalanced food, but the effects persist when larvae are fed a balanced diet. Offspring mortality, fecundity and fertility were positively influenced by parental origin (tree phenotype.

A review is given on atomic vacancies in intermetallic compounds. The intermetallic compounds cover crystalline, quasicrystalline, and bulk metallic glass (BMG) structures. Vacancies can be specifically characterized by their positron lifetimes, by the coincident measurement of the Doppler broadening of the two quanta emitted by positron-electron annihilation, or by time-differential dilatometry. By these techniques, high concentrations and low mobilities of thermal vacancies were found in open-structured B2 intermetallics such as FeAl or NiAl, whereas the concentrations of vacancies are low and their mobilities high in close-packed structure as, e.g., L1{sub 2}-Ni{sub 3}Al. The activation volumes of vacancy formation and migration are determined by high-pressure experiments. The favorable sublattice for vacancy formation is found to be the majority sublattice in Fe{sub 61}Al{sub 39} and in MoSi{sub 2}. In the icosahedral quasicrystal Al{sub 70}Pd{sub 21}Mn{sub 9} the thermal vacancy concentration is low, whereas in the BMG Zr{sub 57}Cu{sub 15.4}Ni{sub 12.6}Nb{sub 3}Al{sub 10} thermal vacancies are found in high concentrations with low mobilities. This may determine the basic mechanisms of the glass transition. Making use of the experimentally determined vacancy data, the main features of atomic diffusion studies in crystalline intermetallics, in quasicrystals, and in BMGs can be understood. Manfred Faehnle and his group have substantially contributed to the theoretical understanding of vacancies and diffusion mechanisms in intermetallics.

These neurotic impostors--as psychologists call them--are not guilty of false humility. The sense of being a fraud is the flip side of giftedness and causes a great many talented, hardworking, and capable leaders to believe that they don't deserve their success. "Bluffing" their way through life (as they see it), they are haunted by the constant fear of exposure. With every success, they think, "I was lucky this time, fooling everyone, but will my luck hold? When will people discover that I'm not up to the job?" In his career as a management professor, consultant, leadership coach, and psychoanalyst, Manfred F.R. Kets de Vries has found neurotic impostors at all levels of organizations. In this article, he explores the subject of neurotic imposture and outlines its classic symptoms: fear of failure, fear of success, perfectionism, procrastination, and workaholism. He then describes how perfectionist overachievers can damage their careers, their colleagues' morale, and the bottom line by allowing anxiety to trigger self-handicapping behavior and cripple the very organizations they're trying so hard to please. Finally, Kets de Vries offers advice on how to limit the incidence of neurotic imposture and mitigate its damage through discreet vigilance, appropriate intervention, and constructive support.

There are several reasons why a real-data receiver function differs from the theoretical receiver function in a 1D model representing the stratification under the seismometer. Main reasons are ambient noise, spectral deficiencies in the impinging P-waveform, and wavefield propagation in laterally varying velocity variations. We present a rapid "2.5D" modelling approach which takes these aspects into account, so that a given 3D velocity model of the crust and uppermost mantle can be tested more realistically against observed recordings from seismometer arrays. Each recorded event at each seismometer is simulated individually through the following steps: A 2D section is extracted from the 3D model along the direction towards the hypocentre. A properly slanted plane or curved impulsive wavefront is propagated through this 2D section, resulting in noise free and spectrally complete synthetic seismometer data. The real vertical component signal is taken as a proxy of the real impingent wavefield, so by convolution and subsequent addition of real ambient noise recorded just before the P-arrival we get synthetic vertical and horizontal component data which very closely match the spectral signal content and signal to noise ratio of this specific recording. When these realistic synthetic data undergo exactly the same receiver function estimation and subsequent graphical display we get a much more realistic image to compare to the real-data receiver functions. We applied this approach to the Central Fjord area in East Greenland (Schiffer et al., 2013), where a 3D velocity model of crust and uppermost mantle was adjusted to receiver functions from 2 years of seismometer recordings and wide angle crustal profiles (Schlindwein and Jokat, 1999; Voss and Jokat, 2007). Computationally this substitutes tens or hundreds of heavy 3D computations with hundreds or thousands of single-core 2D computations which parallelize very efficiently on common multicore systems.

In the autumn, stems of woody perennials such as forest trees undergo a transition from active growth to dormancy. We used microarray transcriptomic profiling in combination with a proteomics analysis to elucidate processes that occur during this growth-to-dormancy transition in a conifer, white spruce (Picea glauca[Moench] Voss). Several differentially expressed genes were likely associated with the developmental transition that occurs during growth cessation in the cambial zone and the concomitant completion of cell maturation in vascular tissues. Genes encoding for cell wall and membrane biosynthetic enzymes showed transcript abundance patterns consistent with completion of cell maturation, and also of cell wall and membrane modifications potentially enabling cells to withstand the harsh conditions of winter. Several differentially expressed genes were identified that encoded putative regulators of cambial activity, cell development and of the photoperiodic pathway. Reconfiguration of carbon allocation figured centrally in the tree's overwintering preparations. For example, genes associated with carbon-based defences such as terpenoids were down-regulated, while many genes associated with protein-based defences and other stress mitigation mechanisms were up-regulated. Several of these correspond to proteins that were accumulated during the growth-to-dormancy transition, emphasizing the importance of stress protection in the tree's adaptive response to overwintering. © 2011 Blackwell Publishing Ltd.

Climate warming is expected to increase the seasonal duration of photosynthetic carbon fixation and tree growth in high-latitude forests. However, photoperiod, a crucial cue for seasonality, will remain constant, which may constrain tree responses to warming. We investigated the effects of temperature and photoperiod on weekly changes in photosynthetic capacity, leaf biochemistry and growth in seedlings of a boreal evergreen conifer, white spruce [Picea glauca (Moench) Voss]. Warming delayed autumn declines in photosynthetic capacity, extending the period when seedlings had high carbon uptake. While photoperiod was correlated with photosynthetic capacity, short photoperiods did not constrain the maintenance of high photosynthetic capacity under warming. Rubisco concentration dynamics were affected by temperature but not photoperiod, while leaf pigment concentrations were unaffected by treatments. Respiration rates at 25 °C were stimulated by photoperiod, although respiration at the growth temperatures was increased in warming treatments. Seedling growth was stimulated by increased photoperiod and suppressed by warming. We demonstrate that temperature is a stronger control on the seasonal timing of photosynthetic down-regulation than is photoperiod. Thus, while warming can stimulate carbon uptake in boreal conifers, the extra carbon may be directed towards respiration rather than biomass, potentially limiting carbon sequestration under climate change. © 2017 John Wiley & Sons Ltd.

We have established a list of lichen- and moss flora of a waterway to be developed for hydropower production (Vangjolo) and in a control water system (Roesgrovi), both in Voss in Hordaland. The waterways have similar bedrock, exposure, vegetation and elevation. To monitor any change in the flora, it was laid out 20 fixed routes from each river systems where low-and moss flora were recorded. To relate this to the monitoring of potential impacts, l flow, humidity, air temperature, water temperature and dew point temperature were logged. It was recorded 66 species total for Roesgrovi and Vangjolo, and 32 mosses, 29 lichens and 5 vascular plants. The results show that the rivers are so similar to the low-and moss flora that they can form the basis for further investigations. This is also shown by the DCA-analyses. The waterways comprises a combination of species with the same requirements as to moisture, and contains species of high and low Ellenberg indicator values for moisture. There is no statistically significant difference between Roesgrovi and Vangjolo in the fixed routes average values. The hydrological and local climatic measurements also show that the river systems are comparable for further study of possible changes after development. (eb)

Downward Migration of Coastal Conifers as a Response to Recent Land Emergence in Eastern Hudson Bay, Québec

Science.gov (United States)

Bégin, Yves; Bérubé, Dominique; Grégoire, Martin

1993-07-01

Postglacial uplift in the eastern Hudson Bay area is among the most rapid in the world (300 m during the last 8000 yr). Although emergence curves based on 14 C-dated raised shorelines give a consistent basis for modeling relative sea-level changes, such a low-resolution dating method is inappropriate for estimating trends over recent decades. A major downward displacement of white spruce ( Picea glauca (Moench) Voss) and tamarack ( Larix laricina (DuRoi) K. Koch) occurred on protected shores as a response to shoreline retreat during this century. Analysis of the age distribution of trees indicates a progradation of white spruce and tamarack on gently sloping terrain ranging from 1.3 and 2.6 cm/yr, respectively, toward the sea. Improvement of climatic conditions during the 20th century favored such expansion which was probably faster than the real land emergence rates, but recent episodes of high water levels caused regression of forest margins over the highly exposed shores. Nevertheless, the downward trend of the treeline over this century substantiates the projections of 14C-dated coastal emergence curves during the modern period (1.0 to 1.3 cm/yr) by providing an estimate of the maximum rates of shoreline retreat.

Accurate diagnosis of normal pressure hydrocephalus is challenging because the clinical symptoms and radiographic appearance of NPH often overlap those of other conditions, including age-related neurodegenerative disorders such as Alzheimer and Parkinson diseases. We hypothesized that radiologic differences between NPH and AD/PD can be characterized by a robust and objective MR imaging DTI technique that does not require intersubject image registration or operator-defined regions of interest, thus avoiding many pitfalls common in DTI methods. We collected 3T DTI data from 15 patients with probable NPH and 25 controls with AD, PD, or dementia with Lewy bodies. We developed a parametric model for the shape of intracranial mean diffusivity histograms that separates brain and ventricular components from a third component composed mostly of partial volume voxels. To accurately fit the shape of the third component, we constructed a parametric function named the generalized Voss-Dyke function. We then examined the use of the fitting parameters for the differential diagnosis of NPH from AD, PD, and DLB. Using parameters for the MD histogram shape, we distinguished clinically probable NPH from the 3 other disorders with 86% sensitivity and 96% specificity. The technique yielded 86% sensitivity and 88% specificity when differentiating NPH from AD only. An adequate parametric model for the shape of intracranial MD histograms can distinguish NPH from AD, PD, or DLB with high sensitivity and specificity.

Climate change is expected to be pronounced towards higher latitudes and altitudes. Warming triggers treeline and vegetation shifts, which may aggravate interspecific competition and affect biodiversity. This research tested the effects of a warming climate, habitat type, and neighboring plant competition on the establishment and growth of white spruce (Picea glauca (Moench) Voss) seedlings in a subarctic mountain region. P. glauca seedlings were planted in June 2010 under 4 different treatments (high/control temperatures, with/without competition) in 3 habitats (alpine ridge above treeline/tundra near treeline /forest below treeline habitats). After two growing seasons in 2011, growth, photosynthesis and foliar C and N data were obtained from a total of 156, one-and-a-half year old seedlings that had survived. Elevated temperatures increased growth and photosynthetic rates above and near treeline, but decreased them below treeline. Competition was increased by elevated temperatures in all habitat types. Our results suggest that increasing temperatures will have positive effects on the growth of P. glauca seedlings at the locations where P. glauca is expected to expand its habitat, but increasing temperatures may have negative effects on seedlings growing in mature forests. Due to interspecific competition, possibly belowground competition, the upslope expansion of treelines may not be as fast in the future as it was the last fifty years.

SutraGUI, a graphical-user interface for SUTRA, a model for ground-water flow with solute or energy transport

Winston, Richard B.; Voss, Clifford I.

2004-01-01

This report describes SutraGUI, a flexible graphical user-interface (GUI) that supports two-dimensional (2D) and three-dimensional (3D) simulation with the U.S. Geological Survey (USGS) SUTRA ground-water-flow and transport model (Voss and Provost, 2002). SutraGUI allows the user to create SUTRA ground-water models graphically. SutraGUI provides all of the graphical functionality required for setting up and running SUTRA simulations that range from basic to sophisticated, but it is also possible for advanced users to apply programmable features within Argus ONE to meet the unique demands of particular ground-water modeling projects. SutraGUI is a public-domain computer program designed to run with the proprietary Argus ONE? package, which provides 2D Geographic Information System (GIS) and meshing support. For 3D simulation, GIS and meshing support is provided by programming contained within SutraGUI. When preparing a 3D SUTRA model, the model and all of its features are viewed within Argus 1 in 2D projection. For 2D models, SutraGUI is only slightly changed in functionality from the previous 2D-only version (Voss and others, 1997) and it provides visualization of simulation results. In 3D, only model preparation is supported by SutraGUI, and 3D simulation results may be viewed in SutraPlot (Souza, 1999) or Model Viewer (Hsieh and Winston, 2002). A comprehensive online Help system is included in SutraGUI. For 3D SUTRA models, the 3D model domain is conceptualized as bounded on the top and bottom by 2D surfaces. The 3D domain may also contain internal surfaces extending across the model that divide the domain into tabular units, which can represent hydrogeologic strata or other features intended by the user. These surfaces can be non-planar and non-horizontal. The 3D mesh is defined by one or more 2D meshes at different elevations that coincide with these surfaces. If the nodes in the 3D mesh are vertically aligned, only a single 2D mesh is needed. For nonaligned

The objective of this study was to investigate the effects of temperature and seed-source elevation on height-growth phenology of three co-occurring and ecologically distinct northern conifers (Pinus contorta Dougl. ex Loud. var. latifolia (lodgepole pine), Picea glauca (Moench) Voss x Picea engelmannii Parry ex Engelm. (interior spruce) and Abies lasiocarpa (Hook.) Nutt. (subalpine fir)). Seed from populations of the three indigenous and co-occurring species was collected across an elevational transect on the southwestern slope of McBride Peak, near Prince George, BC. Collection sites were at elevations of 750 to 1850 m, the latter being close to the tree line. In 2003, seeds were germinated and seedlings raised under favorable growing conditions in a temperature-controlled glasshouse. In 2004, seedlings of each population were grown in natural daylengths at a location within 50 km of the seed collection site both in a temperature-controlled glasshouse and at a nearby field site, and height growth was recorded twice a week throughout the growing season. Species differed in both the date and the accumulated heat sum above 5 degrees C for the initiation and cessation of shoot extension. Growth durations (which integrate growth initiation and growth cessation) were more similar among species in the field than in the glasshouse. This suggests that different mechanisms of phenological control among co-occurring species can result in adaptive "equivalence" under a particular set of climatic conditions.

Full Text Available Corresponding author: Eleanor Voss, Glass and Façade Technology Research Group, Department of Engineering, University of Cambridge, Trumpington Street, Cambridge, UK. E-mail: ev236@cam.ac.uk Process mapping can lead to significant efficiency and quality improvements in construction engineering and is an ideal basis for developing IT support tools. The increasing complexity and multidisciplinary nature of façade design and construction suggest that a process map would be beneficial in this sector of the construction industry, but it has received limited attention to date. This paper presents a verified process map of the façade design and construction process. The map is the first of its kind to represent, in detail, the whole process relevant to all façade types, from commencement of the façade consultant's and contactor's participation, to the end of their involvement. The paper describes the process by which the mapping notation was selected, followed by the development and verification of the process map, including testing in two independent research projects. The BuildingSMART's BPMN notation is found to have superior system features and comprehensibility for this application and the resulting process map is easy to interpret and verify by industry experts. The trialling of the map in the two research projects indicate that the map is a useful tool for assessing process improvements in the façades sector.

Implementation of the Realized Genomic Relationship Matrix to Open-Pollinated White Spruce Family Testing for Disentangling Additive from Nonadditive Genetic Effects

Full Text Available The open-pollinated (OP family testing combines the simplest known progeny evaluation and quantitative genetics analyses as candidates’ offspring are assumed to represent independent half-sib families. The accuracy of genetic parameter estimates is often questioned as the assumption of “half-sibling” in OP families may often be violated. We compared the pedigree- vs. marker-based genetic models by analysing 22-yr height and 30-yr wood density for 214 white spruce [Picea glauca (Moench Voss] OP families represented by 1694 individuals growing on one site in Quebec, Canada. Assuming half-sibling, the pedigree-based model was limited to estimating the additive genetic variances which, in turn, were grossly overestimated as they were confounded by very minor dominance and major additive-by-additive epistatic genetic variances. In contrast, the implemented genomic pairwise realized relationship models allowed the disentanglement of additive from all nonadditive factors through genetic variance decomposition. The marker-based models produced more realistic narrow-sense heritability estimates and, for the first time, allowed estimating the dominance and epistatic genetic variances from OP testing. In addition, the genomic models showed better prediction accuracies compared to pedigree models and were able to predict individual breeding values for new individuals from untested families, which was not possible using the pedigree-based model. Clearly, the use of marker-based relationship approach is effective in estimating the quantitative genetic parameters of complex traits even under simple and shallow pedigree structure.

The time variations of optical emissions during low-latitude auroral events have been shown to correlate well with those of magnetograms in the region where the aurorae are observed. Two events not previously reported are analyzed and are shown to confirm the nature of the correlations found for two earlier events. The maximum optical emissions at mid-latitudes occur in concert with the maximum positive (northward) excursions in the H trace and with rapid fluctuations in the D trace of nearby magnetograms. The fluctuation in ΔD is usually from the east (positive) to the west (negative) in the vicinity of the ΔH perturbation. The positive excursions in H at low-latitude observatories at the time of the maximum optical emissions are associated with negative H excursions at high latitude observatories in the same longitude sector. The source of the particles has been inferred to be the ring current, with precipitation occurring when the |Dst| index is large at the time of the large short term excursions in the local magnetic field. This result is consistent with the funding of Voss and Smith (1979), derived from a series of rocket measurements of precipitating heavy particles, that the flux correlates better with the product of |Dst| and the exponential of K p than with either alone. In the present case it is shown that the product of |Dst| and the amplitude of the short term excursions in the horizontal component in local magnetograms has better time resolution and better correlation with the observed emission rates than the index using K p

Full Text Available A field survey of flowering plants used as food resource by the adults of Heliconius erato phyllis (Fabricius, 1775 was carried out in four sites located in Rio Grande do Sul state, Brazil. Samples were taken in preserved areas of the Atlantic Rain and Myrtaceae forests, an Eucalyptus plantation, and an urban park. Adult feeding frequencies on flowers were registered monthly from December 1996 to May 1997, on plants located on previously marked 200 m long transects. Flowers on which H. erato phyllis fed in the field were collected, drawn and morphometrically characterized. Feeding was registered on flowers of twenty-three species, of which seventeen are new records for H. erato in Brazil . The use of a given plant varied among localities, as a function of its corresponding abundance. The most visited flowers were those of Lantana camara L. and Stachytarpheta cayennensis (Rich. Vahl, followed by Dahliapinnata Voss in the urban site. The data suggest the existence of size and shape convergence between the proboscis and the small, tubular flowers upon which H. eratophyllis feeds. They also indicate that H. eratophyllis adults have an opportunistic nectar feeding / pollen gathering habit, using several of those flowers available in a given time and locality that fit such a morphometrical pattern. Since plant species of both primitive and derived families are used, there is no indication that phylogenetic constraints play a major role in this association, nor that color of flowers, growth pattern or size of the plants are relevant in determining their use by H. erato phyllis.

The information content of Synthetic Aperture Radar (SAR) data significantly included in the radiometric polarization channels, hence polarimetric SAR data should be analyzed in relation with target structure. The importance of the phase difference between two co-polarized scattered signals due to the possible association between the biophysical parameters and the measured Polarization Phase Difference (PPD) statistics of the backscattered signal recorded components has been recognized in geophysical remote sensing. This paper examines two Radarsat-2 images statistics of the phase difference to describe the feasibility of relationship with the physical properties of scattering targets and tries to understand relevance of PPD statistics with various types of forest fields. As well as variation of incidence angle due to affecting on PPD statistics is investigated. The experimental forest pieces that are used in this research are characterized white pine (Pinus strobus L.), red pine (Pinus resinosa Ait.), jack pine (Pinus banksiana Lamb.), white spruce (Picea glauca (Moench Voss), black spruce (Picea mariana (Mill) B.S.P.), poplar (Populus L.), red oak (Quercus rubra L.) , aspen and ground vegetation. The experimental results show that despite of biophysical parameters have a wide diversity, PPD statistics are almost the same. Forest fields distributions as distributed targets have close to zero means regardless of the incidence angle. Also, The PPD distribution are function of both target and sensor parameters, but for more appropriate examination related to PPD statistics the observations should made in the leaf-off season or in bands with lower frequencies.

The reindeer companies of southern Norway: Natural resources, husbandry, prerogatives and challenges (Article in Norwegian and in English

Full Text Available From the middle of the 18th century there have been domesticated reindeer herds in the mountains of South-Norway. The people living in these areas, mostly farmers and hunters, bought reindeer from the Sami further east and north. Or Sami families came with their reindeer and started a new living. These events took place in many regions such as Setesdal, Hardangervidda, Hardanger, Voss, Hallingdal, Valdres, northern Gudbrandsdalen, Norefjell and Rendalen. In 1962 there were 20 000 tame reindeer held by 14 reindeer companies in southern Norway. Today five of these companies still exist. The reindeer owners have organized themselves as joint companies and to be a shareholder one must be living in the local municipality. The four companies in Valdres and northern Gudbrandsdalen keep in all about 11 000 reindeer in the winter herd which produces about 190 tons of reindeer meat each year. The legal basis of this reindeer management is regulated through agreements between the owners of the rough grazing properties and the company. In large areas the Norwegian State is the landowner, and in these cases the so-called Mountain law of 1975 regulates the agreement. The ways of managing the companies will be a matter of adjusting the management to all the other events in society. The structure of the herd, the extent of tameness and degree of domestication are key requisites. It is also of major importance that society supports this kind of management and regards the traditions and the long history of local interests in reindeer management. A future challenge will be to get these ways of living secured and warranted by law.

We sequenced the mitochondrial cytochrome b gene of 141 lowland tapirs (Tapirus terrestris) - representing the largest geographical distribution sample of this species studied across of South America to date. We compare our new data regard to two previous works on population structure and molecular systematics of T. terrestris. Our data agree with the Thoisy et al.'s work in (1) the Northern Western Amazon basin was the area with the highest gene diversity levels in T. terrestris, being probably the area of initial diversification; (2) there was no clear association between haplogroups and specific geographical areas; (3) there were clear population decreases during the last glacial maximum for the different haplogroups detected, followed by population expansions during the Holocene; and (4) our temporal splits among different T. terrestris haplogroups coincided with the first molecular clock approach carried out by these authors (fossil calibration). Nevertheless, our study disagreed regard to other aspects of the Thoisy et al.'s claims: (1) meanwhile, they detected four relevant clades in their data, we put forward six different relevant clades; (2) the Amazon River was not a strong barrier for haplotype dispersion in T. terrestris; and (3) we found reciprocal monophyly between T. terrestris and T. pinchaque. Additionally, we sequenced 42 individuals (T. terrestris, T. pinchaque, T. bairdii, and the alleged "new species", T. kabomani) for three concatenated mitochondrial genes (Cyt-b, COI, and COII) agreeing quite well with the view of Voss et al., and against of the claims of Cozzuol et al. Tapirus kabomani should be not considered as a full species with the results obtained throughout the mitochondrial sequences.

Interspecific variation in resistance of two host tree species to spruce budworm

Woody plants regularly sustain biomass losses to herbivorous insects. Consequently, they have developed various resistance mechanisms to cope with insect attack. However, these mechanisms of defense and how they are affected by resource availability are not well understood. The present study aimed at evaluating and comparing the natural resistance (antibiosis and tolerance) of balsam fir (Abies balsamea [L.] Mill.) and white spruce (Picea glauca [Moench) Voss] to spruce budworm, Choristoneura fumiferana (Clem.), and how drainage site quality as a component of resource availability affects the expression of resistance over time (6 years). Our results showed that there are differences in natural resistance between the two tree species to spruce budworm, but it was not significantly affected by drainage quality. Balsam fir exhibited higher foliar toxic secondary compounds concentrations than white spruce in all drainage classes, resulting in lower male pupal mass, survival and longer male developmental time. This, however, did not prevent spruce budworm from consuming more foliage in balsam fir than in white spruce. This response suggests that either natural levels of measured secondary compounds do not provide sufficient toxicity to reduce defoliation, or spruce budworm has developed compensatory mechanisms, which allow it to utilize food resources more efficiently or minimize the toxic effects that are produced by its host's defensive compounds. Larvae exhibited lower pupal mass and higher mortality in rapidly drained and subhygric sites. Drainage class also affected the amount of foliage destroyed but its impact varied over the years and was probably influenced by climatic variables. These results demonstrate the complexity of predicting the effect of resource availability on tree defenses, especially when other confounding environmental factors can affect tree resource allocation and utilization.

The 395th Wilhelm and Else Heraeus Seminar: `Time-dependent phenomena in Quantum Mechanics' took place at the Heinrich Fabri Institute in Blaubeuren, Germany, 12-16 September 2007. The conference covered a wide range of topics connected with time-dependent phenomena in quantum mechanical systems. The 20 invited talks and 15 short talks with posters at the workshop covered the historical debate between Schrödinger, Dirac and Pauli about the role of time in Quantum Mechanics (the debate was carried out sometimes in footnotes) up to the almost direct observation of electron dynamics on the attosecond time-scale. Semiclassical methods, time-delay, monodromy, variational principles and quasi-resonances are just some of the themes which are discussed in more detail in the papers. Time-dependent methods also shed new light on energy-dependent systems, where the detour of studying the time-evolution of a quantum states allows one to solve previously intractable problems. Additional information is available at the conference webpage http://www.quantumdynamics.de The organizer would like to thank all speakers, contributors, session chairs and referees for their efforts in making the conference a success.

Interspecific Competition and Trade-offs in Resource Allocation are the Key to Successful Growth of Seedlings of White Spruce (Picea glauca (Moench) Voss) at Subarctic Treelines in Warming Alaska.

Alpine treelines in Alaska have advanced for the past 50 years in response to the recent climate warming. However, further increases in temperatures may cause treeline species drought stress and increase susceptibility to insect outbreaks and fire. Complex factors such as soil conditions and plant species composition also impact the growth of seedlings, which are essential to sustain boreal forests. Our goals were to assess 1) the current optimal elevation for the treeline species Picea glauca (white spruce) seedlings and how it is altered by climate change, and 2) their growth/survival strategies at each environmental site. We studied the growth response of spruce seedlings along an altitudinal gradient at 6 sites, consisting of tundra, forest, or transitional ecotone in Denali National Park and one forest site in Fairbanks, AK. In May 2012, four-month old seedlings were planted with or without naturally occurring plants to compare the presence or absence of the interspecific interaction. Summer temperatures were increased by one small greenhouse per site. Over 2 growing seasons, growth was measured non-destructively, and then the seedlings were harvested. Relative growth rate (RGR) in height was increased significantly as the altitude was increased. Elevated temperature increased height only in seedlings at a high-altitude forest. Seedlings with neighboring plants had a higher RGR in height than seedlings that had neighbors removed, while significantly wider diameters were measured from the seedlings without neighbors. A weak trend of declining diameter width with increasing altitudes was seen. Seedlings that grew taller did not grow their stems wider, indicating trade-offs in resource allocation. None of the altitudinal sites had a clear advantage for the growth of the seedlings. Habitat microclimate and the interaction with other species could be more important than the altitude or temperatures and hence, key to the survival and growth of spruce seedlings in this region.

Discrete Ramanujan transform for distinguishing the protein coding regions from other regions.

Based on the study of Ramanujan sum and Ramanujan coefficient, this paper suggests the concepts of discrete Ramanujan transform and spectrum. Using Voss numerical representation, one maps a symbolic DNA strand as a numerical DNA sequence, and deduces the discrete Ramanujan spectrum of the numerical DNA sequence. It is well known that of discrete Fourier power spectrum of protein coding sequence has an important feature of 3-base periodicity, which is widely used for DNA sequence analysis by the technique of discrete Fourier transform. It is performed by testing the signal-to-noise ratio at frequency N/3 as a criterion for the analysis, where N is the length of the sequence. The results presented in this paper show that the property of 3-base periodicity can be only identified as a prominent spike of the discrete Ramanujan spectrum at period 3 for the protein coding regions. The signal-to-noise ratio for discrete Ramanujan spectrum is defined for numerical measurement. Therefore, the discrete Ramanujan spectrum and the signal-to-noise ratio of a DNA sequence can be used for distinguishing the protein coding regions from the noncoding regions. All the exon and intron sequences in whole chromosomes 1, 2, 3 and 4 of Caenorhabditis elegans have been tested and the histograms and tables from the computational results illustrate the reliability of our method. In addition, we have analyzed theoretically and gotten the conclusion that the algorithm for calculating discrete Ramanujan spectrum owns the lower computational complexity and higher computational accuracy. The computational experiments show that the technique by using discrete Ramanujan spectrum for classifying different DNA sequences is a fast and effective method. Copyright © 2014 Elsevier Ltd.

Self-Regulation in the Midst of Complexity: A Case Study of High School Physics Students Engaged in Ill-Structured Problem Solving

Science.gov (United States)

Milbourne, Jeffrey David

The purpose of this dissertation study was to explore the experiences of high school physics students who were solving complex, ill-structured problems, in an effort to better understand how self-regulatory behavior mediated the project experience. Consistent with Voss, Green, Post, and Penner's (1983) conception of an ill-structured problem in the natural sciences, the 'problems' consisted of scientific research projects that students completed under the supervision of a faculty mentor. Zimmerman and Campillo's (2003) self-regulatory framework of problem solving provided a holistic guide to data collection and analysis of this multi-case study, with five individual student cases. The study's results are explored in two manuscripts, each targeting a different audience. The first manuscript, intended for the Science Education Research community, presents a thick, rich description of the students' project experiences, consistent with a qualitative, case study analysis. Findings suggest that intrinsic interest was an important self-regulatory factor that helped motivate students throughout their project work, and that the self-regulatory cycle of forethought, performance monitoring, and self-reflection was an important component of the problem-solving process. Findings also support the application of Zimmerman and Campillo's framework to complex, ill-structured problems, particularly the cyclical nature of the framework. Finally, this study suggests that scientific research projects, with the appropriate support, can be a mechanism for improving students' selfregulatory behavior. The second manuscript, intended for Physics practitioners, combines the findings of the first manuscript with the perspectives of the primary, on-site research mentor, who has over a decade's worth of experience mentoring students doing physics research. His experience suggests that a successful research experience requires certain characteristics, including: a slow, 'on-ramp' to the research

Influence of stocking, site quality, stand age, low-severity canopy disturbance, and forest composition on sub-boreal aspen mixedwood carbon stocks

Low-severity canopy disturbance presumably influences forest carbon dynamics during the course of stand development, yet the topic has received relatively little attention. This is surprising because of the frequent occurrence of such events and the potential for both the severity and frequency of disturbances to increase as a result of climate change. We investigated the impacts of low-severity canopy disturbance and average insect defoliation on forest carbon stocks and rates of carbon sequestration in mature aspen mixedwood forests of varying stand age (ranging from 61 to 85 years), overstory composition, stocking level, and site quality. Stocking level and site quality positively affected the average annual aboveground tree carbon increment (CAAI), while stocking level, site quality, and stand age positively affected tree carbon stocks (CTREE) and total ecosystem carbon stocks (CTOTAL). Cumulative canopy disturbance (DIST) was reconstructed using dendroecological methods over a 29-year period. DIST was negatively and significantly related to soil carbon (CSOIL), and it was negatively, albeit marginally, related to CTOTAL. Minima in the annual aboveground carbon increment of trees (CAI) occurred at sites during defoliation of aspen (Populus tremuloides Michx.) by forest tent caterpillar (Malacosoma disstria Hubner), and minima were more extreme at sites dominated by trembling aspen than sites mixed with conifers. At sites defoliated by forest tent caterpillar in the early 2000s, increased sequestration by the softwood component (Abies balsamea (L.) Mill. and Picea glauca (Moench) Voss) compensated for overall decreases in CAI by 17% on average. These results underscore the importance of accounting for low-severity canopy disturbance events when developing regional forest carbon models and argue for the restoration and maintenance of historically important conifer species within aspen mixedwoods to enhance stand-level resilience to disturbance agents and maintain

Patterns of cross-continental variation in tree seed mass in the Canadian Boreal Forest.

Directory of Open Access Journals (Sweden)

Full Text Available Seed mass is an adaptive trait affecting species distribution, population dynamics and community structure. In widely distributed species, variation in seed mass may reflect both genetic adaptation to local environments and adaptive phenotypic plasticity. Acknowledging the difficulty in separating these two aspects, we examined the causal relationships determining seed mass variation to better understand adaptability and/or plasticity of selected tree species to spatial/climatic variation. A total of 504, 481 and 454 seed collections of black spruce (Picea mariana (Mill. B.S.P., white spruce (Picea glauca (Moench Voss and jack pine (Pinus banksiana Lamb across the Canadian Boreal Forest, respectively, were selected. Correlation analyses were used to determine how seed mass vary with latitude, longitude, and altitude. Structural Equation Modeling was used to examine how geographic and climatic variables influence seed mass. Climatic factors explained a large portion of the variation in seed mass (34, 14 and 29%, for black spruce, white spruce and jack pine, respectively, indicating species-specific adaptation to long term climate conditions. Higher annual mean temperature and winter precipitation caused greater seed mass in black spruce, but annual precipitation was the controlling factor for white spruce. The combination of factors such as growing season temperature and evapotranspiration, temperature seasonality and annual precipitation together determined seed mass of jack pine. Overall, sites with higher winter temperatures were correlated with larger seeds. Thus, long-term climatic conditions, at least in part, determined spatial variation in seed mass. Black spruce and Jack pine, species with relatively more specific habitat requirements and less plasticity, had more variation in seed mass explained by climate than did the more plastic species white spruce. As traits such as seed mass are related to seedling growth and survival, they

Tree growth of boreal forest plays an important role on global carbon (C) cycle, while tree growth in the western Canadian boreal mixed forests has been predicted to be negatively affected by regional drought. Individual tree growth can be controlled by many factors, such as competition, climate, tree size and age. However, information about contributions of different factors to tree growth is still limited in this region. In order to address this uncertainty, tree rings of two dominant tree species, trembling aspen (Populus tremuloides Michx.) and white spruce (Picea glauca (Moench.) Voss), were sampled from boreal mixed forest stands distributed across Alberta, Canada. Tree growth rates over different time intervals (10years interval, 1998-2007; 20years interval, 1988-2007; 30years interval, 1978-2007) were calculated to study the effects of different factors (tree size, competition, climate, and age) on tree growth. Results indicated that tree growth of two species were both primarily affected by competition or tree size, while climatic indices showed less effects on tree growth. Growth of trembling aspen was significantly affected by inter- and intraspecific competition, while growth of white spruce was primarily influenced by tree size, followed by competition. Positive relationship was found between growth of white spruce and competition index of coniferous group, suggesting an intraspecific mutualism mechanism within coniferous group. Our results further suggested that competition driven succession was the primary process of forest composition shift in the western Canadian boreal mixed forest. Although drought stress increased tree mortality, decline of stem density under climate change released competition stress of surviving trees, which in turn sustained growth of surviving trees. Therefore, climatic indices showed fewer effects on growth of dominant tree species compared to other factors in our study. Copyright © 2018 Elsevier B.V. All rights reserved.

Full Text Available Insufficient chilling resulting from rising winter temperatures associated with climate warming has been an area of particular interest in boreal and temperate regions where a period of cool temperatures in fall and winter is required to break plant dormancy. In this study, we examined the budburst and growth of trembling aspen (Populus tremuloides Michx., balsam poplar (Populus balsamifera L., white birch (Betula papyrifera Marsh., black spruce (Picea mariana (Mill. B.S.P., white spruce (Picea glauca (Moench Voss, jack pine (Pinus banksiana Lamb., and lodgepole pine (Pinus contorta Dougl. ex. Loud. seedlings subjected to typical northern Ontario, Canada, spring conditions in climate chambers after different exposures to natural chilling. Results indicate that chilling requirements (cumulative weighted chilling hours differed substantially among the seven species, ranging from 300 to 500 h for spruce seedlings to more than 1100 h for trembling aspen and lodgepole pine. Only spruce seedlings had fulfilled their chilling requirements before December 31, whereas the other species continued chilling well into March and April. Species with lower chilling requirements needed more heat accumulation for budburst and vice versa. Insufficient chilling delayed budburst but only extremely restricted chilling hours (<400 resulted in abnormal budburst and growth, including reduced needle and shoot expansion, early budburst in lower crowns, and erratic budburst on lower stems and roots. Effects, however, depended on both the species’ chilling requirements and the chilling–heat relationship. Among the seven tree species examined, trembling aspen is most likely to be affected by reduced chilling accumulation possible under future climate scenarios, followed by balsam poplar, white birch, lodgepole pine, and jack pine. Black and white spruce are least likely to be affected by changes in chilling hours.

Open-pit mining activities in the oil sands region of Alberta, Canada, create disturbed lands that, by law, must be reclaimed to a land capability equivalent to that existed before the disturbance. Re-establishment of forest cover will be affected by the production and turnover rate of fine roots. However, the relationship between fine root dynamics and tree growth has not been studied in reclaimed oil sands sites. Fine root properties (root length density, mean surface area, total root biomass, and rates of root production, turnover, and decomposition) were assessed from May to October 2011 and 2012 using sequential coring and ingrowth core methods in lodgepole pine (Pinus contorta Dougl.) and white spruce (Picea glauca (Moench.) Voss) stands. The pine and spruce stands were planted on peat mineral soil mix placed over tailings sand and overburden substrates, respectively, in reclaimed oil sands sites in Alberta. We selected stands that form a productivity gradient (low, medium, and high productivities) of each tree species based on differences in tree height and diameter at breast height (DBH) increments. In lodgepole pine stands, fine root length density and fine root production, and turnover rates were in the order of high > medium > low productivity sites and were positively correlated with tree height and DBH and negatively correlated with soil salinity (P < 0.05). In white spruce stands, fine root surface area was the only parameter that increased along the productivity gradient and was negatively correlated with soil compaction. In conclusion, fine root dynamics along the stand productivity gradients were closely linked to stand productivity and were affected by limiting soil properties related to the specific substrate used for reconstructing the reclaimed soil. Understanding the impact of soil properties on fine root dynamics and overall stand productivity will help improve land reclamation outcomes.

Full Text Available Rachel K Voss,1 Tessa N Woods,1 Kate D Cromwell,1 Kelly C Nelson,2 Janice N Cormier1 1Department of Surgical Oncology, 2Department of Dermatology, The University of Texas MD Anderson Cancer Center, Houston, TX, USA Abstract: Patients with thin, low-risk melanomas have an excellent long-term prognosis and higher quality of life than those who are diagnosed at later stages. From an economic standpoint, treatment of early stage melanoma consumes a fraction of the health care resources needed to treat advanced disease. Consequently, early diagnosis of melanoma is in the best interest of patients, payers, and health care systems. This review describes strategies to ensure that patients receive an early diagnosis through interventions ranging from better utilization of primary care clinics, to in vivo diagnostic technologies, to new “apps” available in the market. Strategies for screening those at high risk due to age, male sex, skin type, nevi, genetic mutations, or family history are discussed. Despite progress in identifying those at high risk for melanoma, there remains a lack of general consensus worldwide for best screening practices. Strategies to ensure early diagnosis of recurrent disease in those with a prior melanoma diagnosis are also reviewed. Variations in recurrence surveillance practices by type of provider and country are featured, with evidence demonstrating that various imaging studies, including ultrasound, computed tomography, positron emission tomography, and magnetic resonance imaging, provide only minimal gains in life expectancy, even for those with more advanced (stage III disease. Because the majority of melanomas are attributable to ultraviolet radiation in the form of sunlight, primary prevention strategies, including sunscreen use and behavioral interventions, are reviewed. Recent international government regulation of tanning beds is described, as well as issues surrounding the continued use artificial ultraviolet

During winter evergreens maintain a sustained form of thermal energy dissipation that results in reduced photochemical efficiency measured using the chlorophyll fluorescence parameter Fv/Fm. Eastern white pine (Pinus strobus L.) and white spruce [Picea glauca (Moench) Voss] have been shown to differ in their rate of recovery of Fv/Fm from winter stress. The goal of this study was to monitor changes in photosynthetic protein abundance and phosphorylation status during winter recovery that accompany these functional changes. An additional goal was to determine whether light-dependent changes in light harvesting complex II (LHCII) phosphorylation occur during winter conditions. We used a combination of field measurements and recovery experiments to monitor chlorophyll fluorescence and photosynthetic protein content and phosphorylation status. We found that pine recovered three times more slowly than spruce, and that the kinetics of recovery in spruce included a rapid and slow component, while in pine there was only a rapid component to recovery. Both species retained relatively high amounts of the light harvesting protein Lhcb5 (CP26) and the PsbS protein during winter, suggesting a role for these proteins in sustained thermal dissipation. Both species maintained high phosphorylation of LHCII and the D1 protein in darkness during winter. Pine and spruce differed in the kinetics of the dephosphorylation of LHCII and D1 upon warming, suggesting the rate of dephosphorylation of LHCII and D1 may be important in the rapid component of recovery from winter stress. Finally, we demonstrated that light-dependent changes in LHII phosphorylation do not continue to occur on subzero winter days and that needles are maintained in a phosphorylation pattern consistent with the high light conditions to which those needles are exposed. Our results suggest a role for retained phosphorylation of both LHCII and D1 in maintenance of the photosynthetic machinery in a winter conformation

Morpho-physiological variation of white spruce seedlings from various seed sources and implications for deployment under climate change

Full Text Available Because of changes in climatic conditions, tree seeds originating from breeding programs may no longer be suited to sites where they are currently sent. As a consequence, new seed zones may have to be delineated. Assisted migration consists of transferring seed sources that match the future climatic conditions to which they are currently adapted. It represents a strategy that could be used to mitigate the potential negative consequences of climate change on forest productivity. Decisions with regard to the choice of the most appropriate seed sources have to rely on appropriate knowledge of morpho-physiological responses of trees. To meet this goal, white spruce (Picea glauca [Moench] Voss seedlings from eight seed orchards were evaluated during two years in a forest nursery, and at the end of the first growing season on three plantation sites located in different bioclimatic domains in Quebec.The morpho-physiological responses obtained at the end of the second growing season (2+0 in the nursery made it possible to cluster the orchards into three distinct groups. Modelling growth curves of these different groups showed that the height growth of seedlings from the second-generation and southern first-generation seed orchards was significantly higher than that of those from other orchards, by at least 6%. A multiple regression model with three climatic variables (average growing season temperature, average July temperature, length of the growing season showed that the final height of seedlings (2+0 from the first-generation seed orchards was significantly related to the local climatic conditions at the orchard sites of origin where parental trees from surrounding natural populations were sampled to provide grafts for orchard establishment. Seedling height growth was significantly affected by both seed source origins and planting sites, but the relative ranking of the different seed sources was maintained regardless of reforestation site.

Multisensory interactions are ubiquitous in cortex and it has been suggested that sensory cortices may be supramodal i.e. capable of functional selectivity irrespective of the sensory modality of inputs (Pascual-Leone and Hamilton, 2001; Renier et al., 2013; Ricciardi and Pietrini, 2011; Voss and Zatorre, 2012). Here, we asked whether learning to discriminate visual coherence could benefit from supramodal processing. To this end, three groups of participants were briefly trained to discriminate which of a red or green intermixed population of random-dot-kinematograms (RDKs) was most coherent in a visual display while being recorded with magnetoencephalography (MEG). During training, participants heard no sound (V), congruent acoustic textures (AV) or auditory noise (AVn); importantly, congruent acoustic textures shared the temporal statistics - i.e. coherence - of visual RDKs. After training, the AV group significantly outperformed participants trained in V and AVn although they were not aware of their progress. In pre- and post-training blocks, all participants were tested without sound and with the same set of RDKs. When contrasting MEG data collected in these experimental blocks, selective differences were observed in the dynamic pattern and the cortical loci responsive to visual RDKs. First and common to all three groups, vlPFC showed selectivity to the learned coherence levels whereas selectivity in visual motion area hMT+ was only seen for the AV group. Second and solely for the AV group, activity in multisensory cortices (mSTS, pSTS) correlated with post-training performances; additionally, the latencies of these effects suggested feedback from vlPFC to hMT+ possibly mediated by temporal cortices in AV and AVn groups. Altogether, we interpret our results in the context of the Reverse Hierarchy Theory of learning (Ahissar and Hochstein, 2004) in which supramodal processing optimizes visual perceptual learning by capitalizing on sensory

With climate change, favorable growing conditions for tree species are shifting northwards and to higher altitudes. Therefore, local populations are becoming less adapted to their environment. Assisted migration is one of the proposed adaptive measures to reduce the vulnerability of natural populations and maintain forest productivity. It consists of moving genetic material to a territory where future climate conditions correspond to those of its current location. Eight white spruce ( Picea glauca [Moench] Voss) seed sources representing as many seed orchards were planted in 2013 at three forest sites simulating a south-north climatic gradient of 1.7°C in Québec, Canada. The objectives were to (1) evaluate the morpho-physiological responses of the different seed sources and (2) determine the role of genetic adaptation and physiological plasticity on the observed variation in morpho-physiological traits. Various seedling characteristics were measured, notably height growth from nursery to the fourth year on plantation. Other traits such as biomass and carbon allocation, nutritional status, and various photosynthetic traits before bud break, were evaluated during the fourth growing season. No interaction between sites and seed sources was observed for any traits, suggesting similar plasticity between seed sources. There was no change in the rank of seed sources and sites between years for height growth. Moreover, a significant positive correlation was observed between the height from the nursery and that after 4 years in the plantation. Southern seed sources showed the best height growth, while optimum growth was observed at the central site. Juvenile height growth seems to be a good indicator of the juvenile carbon sequestration and could serve as a selection criterion for the best genetics sources for carbon sequestration.

Reforestation is a primary end use for reconstructed soils following oil sands mining in northern Alberta, Canada. Limited soil water conditions strongly restrict plant growth. Previous research has shown that layering of sandy soils can produce enhanced water availability for plant growth; however, the effect of gradation on these enhancements is not well defined. The objective of this study was to evaluate the effect of soil texture (gradation and layering) on plant available water and consequently on forest productivity for reclaimed coarse textured soils. A previously validated system dynamics (SD) model of soil moisture dynamics was coupled with ecophysiological and biogeochemical processes model, Biome-BGC-SD, to simulate forest dynamics for different soil profiles. These profiles included contrasting 50 cm textural layers of finer sand overlying coarser sand in which the sand layers had either a well graded or uniform soil texture. These profiles were compared to uniform profiles of the same sands. Three tree species of jack pine (Pinus banksiana Lamb.), white spruce (Picea glauce Voss.), and trembling aspen (Populus tremuloides Michx.) were simulated using a 50 year climatic data base from northern Alberta. Available water holding capacity (AWHC) was used to identify soil moisture regime, and leaf area index (LAI) and net primary production (NPP) were used as indices of forest productivity. Published physiological parameters were used in the Biome-BGC-SD model. Relative productivity was assessed by comparing model predictions to the measured above-ground biomass dynamics for the three tree species, and was then used to study the responses of forest leaf area index and potential productivity to AWHC on different soil profiles. Simulated results indicated soil layering could significantly increase AWHC in the 1-m profile for coarse textured soils. This enhanced AWHC could result in an increase in forest LAI and NPP. The increased extent varied with soil

Full Text Available In terms of marketing, online trading is a new distribution channel and trading platforms are products of Investment and Financial Services Companies. Internet shortens the connection between the investor and the products they wish to purchase (shares, futures, CFDs, government securities, bonds, etc., and in some cases it no longer needs a security broker. Increasing use of the Internet and increasing competitiveness between Investment and Financial Services Companies do the latter, to seek new distribution channels to specific products. The purpose of this paper is to examine to what extent the investor education level affects the decision to move from traditional trading to online trading and the benefits and disadvantages of these types of transactions. To whom should the Investment and Financial Services Companies guide their marketing campaign to attract more investors for online platforms? The work presented is part of a larger project that will be part of author thesis, studying other factors that influence the decision to move from traditional to online trading: cost factor, time factor, psychological and social attributes of investors, yield portfolios and technological capacities of Investment and Financial Services Companies. Starting from the idea that with the increase of experience in stock investments the investors will want to make their own decisions, Investment and Financial Services Companies should provide new products. Compared to competitors, an Investment and Financial Services Company must innovate, and information technology currently offers the tools for innovation facilities. At the same time, the existence and development of the Internet has made the transaction without assistance or with minimal human intervention possible (Voss, 2000. The difference is in the knowledge about stock market, the speed the transaction orders arrive in the stock market, direct access to multiple markets, transaction costs and the level

Radiation processes play an important role in the study of both fast ignition and other inertial confinement schemes, such as plasma jet driven magneto-inertial fusion, both in their effect on energy balance, and in generating diagnostic signals. In the latter case, warm and hot dense matter may be produced by the convergence of a plasma shell formed by the merging of an assembly of high Mach number plasma jets. This innovative approach has the potential advantage of creating matter of high energy densities in voluminous amount compared with high power lasers or particle beams. An important application of this technology is as a plasma liner for the flux compression of magnetized plasma to create ultra-high magnetic fields and burning plasmas. HyperV Technologies Corp. has been developing plasma jet accelerator technology in both coaxial and linear railgun geometries to produce plasma jets of sufficient mass, density, and velocity to create such imploding plasma liners. An enabling tool for the development of this technology is the ability to model the plasma dynamics, not only in the accelerators themselves, but also in the resulting magnetized target plasma and within the merging/interacting plasma jets during transport to the target. Welch pioneered numerical modeling of such plasmas (including for fast ignition) using the LSP simulation code. Lsp is an electromagnetic, parallelized, plasma simulation code under development since 1995. It has a number of innovative features making it uniquely suitable for modeling high energy density plasmas including a hybrid fluid model for electrons that allows electrons in dense plasmas to be modeled with a kinetic or fluid treatment as appropriate. In addition to in-house use at Voss Scientific, several groups carrying out research in Fast Ignition (LLNL, SNL, UCSD, AWE (UK), and Imperial College (UK)) also use LSP.

Sky-Radiance Models for Monte Carlo Radiative Transfer Applications

Santos, I.; Dalimonte, D.; Santos, J. P.

Photon-tracing can be initialized through sky-radiance (Lsky) distribution models when executing Monte Carlo simulations for ocean color studies. To be effective, the Lsky model should: 1) properly represent sky-radiance features of interest; 2) require low computing time; and 3) depend on a limited number of input parameters. The present study verifies the satisfiability of these prerequisite by comparing results from different Lsky formulations. Specifically, two Lsky models were considered as reference cases because of their different approach among solutions presented in the literature. The first model, developed by the Harrisson and Coombes (HC), is based on a parametric expression where the sun geometry is the unique input. The HC model is one of the sky-radiance analytical distribution applied in state-of-art simulations for ocean optics. The coefficients of the HC model were set upon broad-band field measurements and the result is a model that requires a few implementation steps. The second model, implemented by Zibordi and Voss (ZV), is based on physical expressions that accounts for the optical thickness of permanent gases, aerosol, ozone and water vapour at specific wavelengths. Inter-comparisons between normalized ^LskyZV and ^LskyHC (i.e., with unitary scalar irradiance) are discussed by means of individual polar maps and percent difference between sky-radiance distributions. Sky-radiance cross-sections are presented as well. Considered cases include different sun zenith values and wavelengths (i.e., λ=413, 490 and 665 nm, corresponding to selected center-bands of the MEdium Resolution Imaging Spectrometer MERIS). Results have shown a significant convergence between ^LskyHC and ^LskyZV at 665 nm. Differences between models increase with the sun zenith and mostly with wavelength. For Instance, relative differences up to 50% between ^ L skyHC and ^ LskyZV can be observed in the antisolar region for λ=665 nm and θ*=45°. The effects of these

Full Text Available A new hydrozoan, Sarsia bella sp. nov. is described in both its hydroid and medusa stage from north of Puget Sound, Washington in the San Juan Islands, USA and off the southernmost tip of Vancouver Island, Canada. The medusa is distinguished from other Sarsia species by 16 exumbrellar nematocyst patches and in being more transparent or glass like when living than any other known species of the genus. The exumbrellar nematocyst patches become indistinct in mature specimens and in those crowded in culture, with single nematocysts increasingly spaced out. The hydroid, both field-collected and raised in culture from its medusa, forms small, upright stolonal colonies not more than 1.5 mm high. The hydranths bear an oral whorl of four to five capitate tentacles, and immediately below a second whorl of slightly shorter capitate tentacles. In thriving colonies there is occasionally a whorl of small filiform tentacles on the lower part of the hydranth. Medusa buds develop in the middle of hydranth below the capitate tentacles and above the reduced filiform tentacles, if present. Young medusae are liberated with the typical 16 exumbrellar nematocyst patches. The hydroid of this species was originally mistaken for the hydroid of Polyorchis penicillatus. Brinckmann-Voss (1977 reported a small corynid hydroid living on the margin of rock scallop shells. Medusae liberated from this hydroid were at that time believed to be those of Polyorchis penicillatus (Eschscholtz present in the plankton. Immature medusae of these two species appear strikingly similar, especially with regard to their exumbrellar nematocyst patches, four tentacles and abaxial ocelli. Since then however, this connection has been proven wrong, because an identical hydroid was raised from the medusae of the new species Sarsia bella. Second generation medusae raised in the laboratory were carefully compared with medusae liberated from field collected hydroids (thought to have been Polyorchis

Fuel cycle externalities are the costs imposed on society and the environment that are not accounted for by the producers and consumers of energy. They include damage to health, forests, crops, natural ecosystems and the built environment. Traditional assessment of fuel cycles has ignored these effects and the energy sector is consequently distorted in favor of technologies with significant environmental burdens. Concern over widespread degradation of the environment resulting from fuel cycle emissions has mounted since the late 1960s. In the early 1970s the potential for long range atmospheric transport of certain pollutants was recognized. The effects of acidifying pollutants, ozone precursors and greenhouse gases have caused particular concern. This is reflected in recent trends in economic thought, particularly the emphasis on sustainable development and the use of market mechanisms for environmental regulation. It has thus become increasingly clear that the external impacts of energy use are significant and should be considered by energy planners. Although the theoretical basis for including external costs in decision making processes has been generally agreed, an acceptable methodology for their calculation and integration has not been established. The studies of Hohmeyer (1988), Ottinger et al. (1990) and Friedrich and Voss (1993) provide the background for such work, though they are of a somewhat preliminary nature. We need to improve the methods employed and the quality of models and data used so that planning decisions can be based at least partly on the results. It is particularly important that the site and project specificity of many impacts is recognized. In consequence of this a collaborative project between Directorate General XII (Science, Research and Technology) of the European Commission and the United States Department of Energy has been established to identify the most appropriate methodology for this type of work.

Zone (JMFZ) system and the Færøy archipelago. Our unpublished data on the conjugate margin of the eastern Jan Mayen ridge confirm this. North of the JMFZ, early magmatism appears to be caused by the combined effect of elevated temperature and convection, while there is a rapid transition to predominantly temperature dominated melting ~2 M.y. after breakup. This is similar to the northern conjugate East Greenland profiles we examined (Voss and Jokat, 2007), while the southern of their two profiles indicates that convection is not turned off at that side. Conjugate differences in igneous crustal thickness further indicate asymmetric conjugate magmatic development. For comparison, we applied the same analysis to data from the Vøring Spur located off the Vøring Margin, and the igneous crust beneath the Jan Mayen Island. Both show little H-Vp correlation with generally lowVp, indicating that these igneous features were created through low-degree mantle melting created by some kind of mantle convection without an elevated temperature component.

PLGA was dissolved in a mixture of methylene chloride and dimethyl formamide (2:3 at a concentration of 2.3 wt%, and nanodiamond (ND powder was added at a concentration of 0.7 wt% (about 23 wt% in dry PLGA.Results: In the composite scaffolds, the ND particles were either arranged like beads in the central part of the fibers or formed clusters protruding from the fibers. In the PLGA-ND membranes, the fibers were thicker (diameter 270 ± 9 nm than in pure PLGA meshes (diameter 218 ± 4 nm, but the areas of pores among these fibers were smaller than in pure PLGA samples (0.46 ± 0.02 µm2 versus 1.28 ± 0.09 µm2 in pure PLGA samples. The PLGA-ND membranes showed higher mechanical resistance, as demonstrated by rupture tests of load and deflection of rupture probe at failure. Both types of membranes enabled the attachment, spreading, and subsequent proliferation of human osteoblast-like MG-63 cells to a similar extent, although these

The Effect of sunlight radiation, rainfall and droplet spectra of sprays on per ‐sistence of a Bacillus thuringiensis subspp. kurstaki (Btk) formulation, DiPel? 76AF, was examined after application onto spruce [Picea glauca (Moench) Voss] foliage. The investigation consisted of three studies: (i) Study I: a laboratory microcosm study to examine the photostability of DiPel 76AF deposits on foliage after different periods of exposure to two radiation intensities, (ii) Study II: a laboratory microcosm study to examine the rainfastness of foliar deposits after exposure to different amounts of rainfall consisting of two separate droplet spectra, and (iii) Study III: a field microcosm study to investigate the influence of two different droplet spectra of DiPel 76AF sprays on foliar persistence of Btk under natural weathering conditions. In all studies, persistence of Btk was investigated both by bioassay [using spruce budworm (Choristoneura fumiferana Clemens)] and total protein assay.The findings of Study I indicated that bioactivity of foliar deposits decreased with increasing duration of exposure to radiation, and with increasing radiation intensity. The half‐life (DT 50 , the exposure period required for 50% of the initial bioactivity to disappear) was 5.1 d for the low intensity, and 3.9 d for the higher intensity. In contrast with the bioassay results, the total protein levels [determined by the bicinchoninic acid (BCA) method] showed no decrease with increasing duration of exposure, or with increasing radiation intensity.The findings of Study II indicated that bioactivity of foliar deposits decreased with increasing cumulative rainfall. A new term, RF 50 [the amount of rain (in mm) required to washoff 50% of the initial deposit], was introduced to understand the relationship between rainfall intensity and reduction in bioactivity. When the same amount of rain was applied in different droplet sizes, the RF 50 value was high (5.2 mm) for the small rain droplets

submitted 227 contributions, which were intensively discussed during day and evening sessions. The scientific program was centered around invited talks from speakers outside the μSR community, who presented lectures on topics where μSR is giving or expected to give significant contributions. The invited speakers, covering various fields of interest, included Radu Coldea (Oxford, Quantum Magnetism), Claude- Henri Delmas (Bordeaux, Electro- and Solid State Chemistry), Dirk Johrendt (Munich, Iron Based Materials), Marc-Henri Julien (Grenoble, Cuprate Superconductors), Manfred Fiebig (Zürich, Multiferroics), Allan MacDonald (Austin, Topological Electronic States), Hidenori Takagi (Stuttgart and Tokyo, Transition Metal Oxides), and Jean-Marc Triscone (Geneva, Oxide Heterostructures). In addition to an overview about status and progress of the existing facilities in Europe, Canada and Japan, future projects and new ideas for μSR facilities in South Korea, China and the USA were presented. A special evening session was held to discuss about muon site and muon states calculations by DFT and other techniques. Several talks and posters can be found on the conference web page www.psi.ch/muSR2014. In a ceremony at the beginning of the conference, Roberto De Renzi from the University of Parma was awarded the 2014 Yamazaki Prize for muon science by the International Society for Muon Spin Spectroscopy (ISMS) for his sustained and exceptional contributions to the development of the muon spin relaxation technique to investigate magnetism and superconductivity and for promoting synergies between μSR and NMR. In the closing session Rob Kie (UBC Vancouver and TRIUMF) very effectively summarized the five days of meeting, while giving an enlightening personal impression. In the same session five best poster prizes were awarded and ISMS gave two prizes to young researchers presenting outstanding work at the conference. The conference organizers also on behalf of the entire μSR community are

temperature dataset, Australian Climate Observations Reference Network - Surface Air Temperature (ACORN-SAT) [BoM, 2012b]. This dataset contains daily homogenised surface temperature observations for 112 locations around Australia, dating back to 1910. An ontology for the dataset was developed [Lefort et. al., 2012], based on the existing Semantic Sensor Network ontology [Compton et. al., 2012] and the W3C RDF Data Cube vocabulary [W3C, 2012]. Additional vocabularies were developed, e.g. for BoM weather stations and rainfall districts. The dataset was converted to RDF and loaded into an RDF triplestore. The Linked-Data API (http://code.google.com/p/linked-data-api) was used to configure specific URI query patterns (e.g. for observation timeseries slices by station), and a SPARQL endpoint was provided for direct querying. In addition, some demonstration 'mash-ups' were developed, providing an interactive browser-based interface to the temperature timeseries.

QED. Another rapidly growing research field (although its origin can be traced to the beginning of the 1980s) is the quantum control of evolution at the microscopic level. These examples show that quantum non-stationary systems continue to be a living and very interesting part of quantum physics, uniting researchers from many different areas. Thus it is no mere chance that several special scientific meetings devoted to these topics have been organized recently. One was the international seminar 'Time-Dependent Phenomena in Quantum Mechanics' organized by Manfred Kleber and Tobias Kramer in 2007 at Blaubeuren, Germany. The proceedings of that event were published in 2008 as volume 99 of Journal of Physics: Conference Series. Another recent meeting was the International Workshop on Quantum Non-Stationary Systems, held on 19-23 October 2009 at the International Center for Condensed Matter Physics (ICCMP) in Brasilia, Brazil. It was organized and directed by Victor Dodonov (Institute of Physics, University of Brasilia, Brazil), Vladimir Man'ko (P N Lebedev Physical Institute, Moscow, Russia) and Salomon Mizrahi (Physics Department, Federal University of Sao Carlos, Brazil). This event was accompanied by a satellite workshop 'Quantum Dynamics in Optics and Matter', organized by Salomon Mizrahi and Victor Dodonov on 25-26 October 2009 at the Physics Department of the Federal University of Sao Carlos, Brazil. These two workshops, supported by the Brazilian federal agencies CAPES and CNPq and the local agencies FAP-DF and FAPESP, were attended by more than 120 participants from 16 countries. Almost 50 invited talks and 20 poster presentations covered a wide area of research in quantum mechanics, quantum optics and quantum information. This special issue of CAMOP/Physica Scripta contains contributions presented by some invited speakers and participants of the workshop in Brasilia. Although they do not cover all of the wide spectrum of problems related to quantum non

spectra in 1836. The authors quote details from the observing book and present some sketches (whose reproduction is somewhat poor, and the reader is referred to Häfner's history of Munich Observatory, discussed elsewhere in this volume of JAD, to see a better colour reproduction of a spectral sketch of Lamont). The impact of these studies (or rather the lack of it) is also briefly reviewed. Manfred Strumpf (Gotha) describes the difficulties in finding suitable directors for the Gotha Observatory - when the funds became smaller and the post thus became less and less attractive. Only the wealthy Nikolaus von Konkoly, a serious amateur and pioneer of astrophysics, applied even twice, but the administration was reluctant to seriously consider his offer. The result was that the chosen candidates were mainstream astronomers who used Gotha only as a step to foster their career and to find a better position as soon as possible. Finally, Peter Brosche (Daun) and Endre Zsoldos (Budapest) trace the life of a hitherto elusive craftsman-scientist, Friedrich Schwab. He was chosen to be the mechanic of one of the Venus transit expeditions of the German Empire (1882 to Punta Arenas), became university mechanic in Klausenburg, and later teacher at the technical school in Ilmenau. He was an active observer of variable stars and also a specialist in endomological studies. The authors have located a grand-son and have put to light some valuable notes and photographs. As can be seen from the summaries given above, this collection of essays deals mainly with historical events that occurred in Germany and neighboring countries, and focuses mainly on events in the 17th to 19th centuries. All contributions are written in German. The editors have taken care that generally a high standard was kept, although topic and realization make some articles more pleasant to read than others.

uncontrolled or premature differentiation and the onset of senescence [12]. Stressing the importance of in vitro environments, even regulatory agencies like the US-FDA use in vitro manipulation as a gauge to classify cell therapies[13]. In this issue, a diverse assortment of articles ranging from the use of scaffolds for in vitro culture by Gomathysankar et al [14] to employing tools for in vivo transplantation of cells by Maiti et al [15]and Fauzi et al [16] have been published. During regenerative medicine applications, cells undergo several transitions across environments, starting with an in vivo to in vitro transition when harvested from the body and subjected to culture-expansion or tissue engineering kind of processing and then a reversal back to an in vivo environment. While the factors and materials employed in the in vitro eco-system are known, their effects are known though to an extent, some of their implications still remain unknown and the mechanisms of those implications are largely obscure [17-19]. These bunch of changes in the whole eco-system inside-out and vice versa need a meticulous and flawless assessment which is indispensable in improvising the clinical outcome of regenerative medicine applications.

We demonstrates how the theory accounts for a wide variety of phenomena regarding the interpretation of superlative quantifiers, their distribution, and the contexts in which they can be embedded.ReferencesBolinger, D. 1978. ‘Yes-No Questions are not Alternative Questions’.

of all 12 volumes in a library so that they may be accessible to future scholars on request. As Appendix II shows, those of interest to modern day plasma physicists are contained in volumes 3, 4 and 5. Postscript (added December 2008) Following the October 2008 online publication of our Editorial, we are grateful to Professor Manfred Hellberg of the University of KwaZulu-Natal (Durban, South Africa) for drawing our attention to a letter by H M Mott-Smith, one of Langmuir's co-workers, published in 1971 (Nature 233 219). In this letter Mott-Smith makes clear his recollection that Langmuir was struck by the analogy between 'the way blood plasma carries around red and white corpuscles and germs' and the way that the ' . . . "equilibrium" part of the discharge acted as a sort of sub-stratum carrying particles of special kinds, like high-velocity electrons from thermionic filaments, molecules and ions of gas impurities'. We thus conclude that this now settles the origin of the term.

In Memoriam Dr. habil. phys. Inta Muzikante (08.01.1951-15.02.2012) Inta Muzikante Inta was born in Valmiera, a town in the northern part of Latvia. She attended school in Sigulda and high school in Riga. While at the high-school, Inta decided to study natural sciences. After graduating from high-school in 1969 she entered the physics section of the Physics and Mathematics department of University of Latvia and obtained her university degree in 1974. In parallel with University studies, Inta started to work at the Semiconductor Physics Research Lab at the University of Latvia. After graduating she was offered a position at the Physical Energetics institute of the Latvian Academy of Sciences, in the laboratory of Professor Edgars Silinsh, one of the most internationally well known Latvian physicists. Inta started researching electronic and photoelectric processes in organic crystals and thin films. This was a novel field, pioneered both internationally and in Latvia by Profesors E Silinsh, O Neilands and J Freimanis. It could be said that Inta stood at the cradle of this research field and stayed faithful to it all of her life. Her work was very successful and within a few years she advanced from research assistant to researcher and then leading research scientist. Her first scientific topic was studies of the mechanism of charge carrier photogeneration and separation in organic molecular crystals. In 1983 for a work
