  2. The awaited miracle: reflections of Marian apparitions in Garabandal, Spain

    Directory of Open Access Journals (Sweden)

    Niklas Sjöström

    2010-01-01

    Full Text Available This article reflects upon Marian apparitions that occurred during the years 1961 to 1965 in the village of San Sebastián de Garabandal, or Garabandal, in northern Spain, giving rise to pilgrimages ever since. The events coincided with the Second Ecumenical Council of the Vatican, or Vatican II. Garabandal is the only Marian apparition event to have prophesied and commented on Vatican II. Nevertheless, in Christendom, travelling to Garabandal is regarded as an alternative pilgrimage.The pilgrimage route is in several ways unique compared to journeys to other Marian pilgrimage shrines, since it has not yet been approved by the Catholic Church. Pilgrimages to Garabandal were even officially forbidden for several years. The Catholic Church authorities originally declared travelling to Garabandal as forbidden for church officials such as priests and others. This article gives an overview of the case of Garabandal through the years and reflect upon why this place is considered special in comparison to other pilgrimage sites. The study examines such aspects of pilgrimages to this village as location and motivation, the Virgin Mary and Marian apparitions and also the messages and miracles of Garabandal.

  3. Effect of environmental conditions on flower induction of marian plum (Bouea burmanica Griff

    Full Text Available Marian plum flowering naturally occurs during the cool, dry season so Thailand farmers usually withdraw irrigation a month before flowering. However, irregular flowering continues to be a serious problem. This study investigated the effects of environmental conditions (air temperature, soil moisture and relative humidity on flower induction of marian plum. Daily weather data were collected using weather stations in three orchards where flowering was also recorded. Thirty representative trees per orchard were randomly selected for data collection. The results showed that trees from all orchards flowered in response to low temperature (below 18 °C despite different levels of water stress and relative humidity. These results indicated that soil moisture content and relative humidity had no influence on marian plum flower induction but enhanced flower bud development. Night temperatures of 18 °C or lower are essential for marian plum flower induction.

  8. From Jack to Double Jack Polynomials via the Supersymmetric Bridge

    Science.gov (United States)

    Lapointe, Luc; Mathieu, Pierre

    2015-07-01

    The Calogero-Sutherland model occurs in a large number of physical contexts, either directly or via its eigenfunctions, the Jack polynomials. The supersymmetric counterpart of this model, although much less ubiquitous, has an equally rich structure. In particular, its eigenfunctions, the Jack superpolynomials, appear to share the very same remarkable combinatorial and structural properties as their non-supersymmetric version. These super-functions are parametrized by superpartitions with fixed bosonic and fermionic degrees. Now, a truly amazing feature pops out when the fermionic degree is sufficiently large: the Jack superpolynomials stabilize and factorize. Their stability is with respect to their expansion in terms of an elementary basis where, in the stable sector, the expansion coefficients become independent of the fermionic degree. Their factorization is seen when the fermionic variables are stripped off in a suitable way which results in a product of two ordinary Jack polynomials (somewhat modified by plethystic transformations), dubbed the double Jack polynomials. Here, in addition to spelling out these results, which were first obtained in the context of Macdonal superpolynomials, we provide a heuristic derivation of the Jack superpolynomial case by performing simple manipulations on the supersymmetric eigen-operators, rendering them independent of the number of particles and of the fermionic degree. In addition, we work out the expression of the Hamiltonian which characterizes the double Jacks. This Hamiltonian, which defines a new integrable system, involves not only the expected Calogero-Sutherland pieces but also combinations of the generators of an underlying affine {widehat{sl}_2} algebra.

  9. MARIANE: MApReduce Implementation Adapted for HPC Environments

    Energy Technology Data Exchange (ETDEWEB)

    Fadika, Zacharia; Dede, Elif; Govindaraju, Madhusudhan; Ramakrishnan, Lavanya

    2011-07-06

    MapReduce is increasingly becoming a popular framework, and a potent programming model. The most popular open source implementation of MapReduce, Hadoop, is based on the Hadoop Distributed File System (HDFS). However, as HDFS is not POSIX compliant, it cannot be fully leveraged by applications running on a majority of existing HPC environments such as Teragrid and NERSC. These HPC environments typicallysupport globally shared file systems such as NFS and GPFS. On such resourceful HPC infrastructures, the use of Hadoop not only creates compatibility issues, but also affects overall performance due to the added overhead of the HDFS. This paper not only presents a MapReduce implementation directly suitable for HPC environments, but also exposes the design choices for better performance gains in those settings. By leveraging inherent distributed file systems' functions, and abstracting them away from its MapReduce framework, MARIANE (MApReduce Implementation Adapted for HPC Environments) not only allows for the use of the model in an expanding number of HPCenvironments, but also allows for better performance in such settings. This paper shows the applicability and high performance of the MapReduce paradigm through MARIANE, an implementation designed for clustered and shared-disk file systems and as such not dedicated to a specific MapReduce solution. The paper identifies the components and trade-offs necessary for this model, and quantifies the performance gains exhibited by our approach in distributed environments over Apache Hadoop in a data intensive setting, on the Magellan testbed at the National Energy Research Scientific Computing Center (NERSC).

    2004-01-01

    The precise alignment of the 1232 dipoles, 474 Short Straight Sections (SSS) and some other components of the LHC collider, requires the use of 6800 jacks. The specific requirements and the need for a cost-effective solution for this large production, justified the development and industrialisation of a dedicated mechanical jack. The jack was developed, and is now being produced by Centre for Advanced Technology, India, in the framework of a collaboration between CERN and the Department of Atomic Energy in India. Three jacks support each of the 32-ton heavy, 15-meter long cryo-dipole of LHC, and provide the required alignment features. Identical jacks support the lighter LHC Short Straight Sections. Presently, the mass production of 6800 jacks is in progress with two Indian manufacturers, and 3545 jacks have already been delivered to CERN by April 2004. Considering the successful performance of the jacks, it is now envisaged to extend their use, with some modifications, for even higher-demanding alignment of ...

  18. De heroínas y mujeres. La trayectoria cinematográfica del personaje de Lady Marian

    Directory of Open Access Journals (Sweden)

    Pérez Herrera, Gema

    2016-06-01

    Full Text Available The transformation of the role of women over the course of the 20th century can be seen particularly clearly in the cinema. The analysis of various cinematic representations of Lady Marian, Robin Hood’s romantic partner, reveals the transformation in the female from feminine to heroic between 1922 and the present. This change involves Marian adopting male roles and being included in scenes that were previously reserved for male characters, together with a progressive masculinisation of women. Analysing films made in different decades shows how cinema always conveys a contemporary message, reflecting human and cultural models in keeping with the sensitivities of its viewers.La revolución histórica de la mujer a lo largo del siglo XX ha tenido su correlato en un testigo de excepción: el cine. El análisis de varias representaciones cinematográficas de Lady Marian, protagonista femenina de la leyenda de Robin Hood, desde 1922 hasta algunas de las producciones más recientes permite señalar que se ha producido un cambio en el papel de lo femenino en lo heroico. Este cambio pasa por la adopción de roles y la inclusión en escenarios antaño reservados para el protagonismo masculino, así como por una progresiva masculinización de la mujer. El análisis de las representaciones realizadas en cada década del siglo XX permite también comprobar cómo el cine siempre proyecta un mensaje contemporáneo, reflejando en sus historias modelos humanos y culturales acordes con la sensibilidad de cada tiempo.

    2015-12-01

    Full Text Available In this paper we outline some of the research results of a larger work which studies the Bolivian migration from a gender perspective, as well as the impact of the institutional practices that determine the transnational experience. In a global scene of restrictive rules concerning the human mobility, we notice how control and dominance strategies are present in ideologies and symbolic mechanisms. Women options in the migration process are trapped through them. We propose to recognize the symbolic and institutional violence that pressures migrants during their migration journey, focusing on understanding the ideological content — sexism and marianism — in which they are based on. We present an analysis of the instrumented ways of applying violence against Bolivian migrant women and its families from the social action practices implemented at origin and destination (transnational perspective.

    Full Text Available Introduction Introduction Marian thistle (Silybum marianum L. is a medicinal, herbaceous and annuals plant belongs to the Asteraceae family which is used to treat liver disease. The essential oil of Marian thistle seeds is the type of flavonolignans (phenols family that forms 1.5 to 3% of its seeds weight. The important flavonoids found in the seeds of this plant are silybin, silychristin and silydianin is known as silymarin compounds, that is yellow. Increasing the desired compounds of medicinal plants is possible by cultivation techniques manipulation such as irrigation, fertilization or photo-bioreactor systems. Water deficient is the most important factors limiting the growth and yield of medicinal crops, especially in arid and semi-arid regions. Bio-fertilizers as an alternative in some cases and in most cases as a complement to chemical fertilizers can help to ensure the sustainability of agricultural production systems. Han et al. (2006 in the study of the effect of phosphate solubilizing bacteria (PSB, Bacillus megaterium var. phosphaticum and potassium solubilizing bacteria (KSB, Bacillus mucilaginosus in nutrient limited soil planted with pepper and cucumber stated that Rock P and K applied either singly or in combination did not significantly enhance soil availability of P and K. PSB was a more potent P-solubilizer than KSB, and co-inoculation of PSB and KSB resulted in consistently higher P and K availability than in the control. Rock P with inoculation of PSB increased the availability of P and K, the uptake of N, P and K by shoots and roots, and the growth of both pepper and cucumber. Similar but less pronounced results were obtained when rock K and KSB were added concomitantly. Combined together, rock materials and both bacterial strains consistently increased further mineral availability, uptake and plant growth, suggesting their potential use as fertilizer. The present study was designed to evaluate the effect of bio

  3. Jack superpolynomials: physical and combinatorial definitions

    International Nuclear Information System (INIS)

    Desrosiers, P.; Mathieu, P.; Lapointe, L.

    2004-01-01

    Jack superpolynomials are eigenfunctions of the supersymmetric extension of the quantum trigonometric Calogero-Moser-Sutherland Hamiltonian. They are orthogonal with respect to the scalar product, dubbed physical, that is naturally induced by this quantum-mechanical problem. But Jack superpolynomials can also be defined more combinatorially, starting from the multiplicative bases of symmetric superpolynomials, enforcing orthogonality with respect to a one-parameter deformation of the combinatorial scalar product. Both constructions turn out to be equivalent. (author)

  4. Then and Now: Memories of a Patriarchal Ireland in the Work of Marian Keyes

    Directory of Open Access Journals (Sweden)

    Ryan, Mary

    2011-01-01

    Full Text Available This paper will observe how the work of Irish author Marian Keyes is influenced by,and representative of, the place of women in Ireland in terms of historical issues, social values,and legal issues. It will discuss two primary areas that have affected women in Irish society: the family and the female body. In addressing how such issues were traditionally viewed in Irish society, this paper will demonstrate how Keyes’ novels present an awareness –a memory– of how Irish women’s lives were once repressed by patriarchal values, and how contemporary women still, to some extent, feel the effects –the restraints– of such attitudes.

  5. JACK - ANTHROPOMETRIC MODELING SYSTEM FOR SILICON GRAPHICS WORKSTATIONS

    Science.gov (United States)

    Smith, B.

    1994-01-01

    JACK is an interactive graphics program developed at the University of Pennsylvania that displays and manipulates articulated geometric figures. JACK is typically used to observe how a human mannequin interacts with its environment and what effects body types will have upon the performance of a task in a simulated environment. Any environment can be created, and any number of mannequins can be placed anywhere in that environment. JACK includes facilities to construct limited geometric objects, position figures, perform a variety of analyses on the figures, describe the motion of the figures and specify lighting and surface property information for rendering high quality images. JACK is supplied with a variety of body types pre-defined and known to the system. There are both male and female bodies, ranging from the 5th to the 95th percentile, based on NASA Standard 3000. Each mannequin is fully articulated and reflects the joint limitations of a normal human. JACK is an editor for manipulating previously defined objects known as "Peabody" objects. Used to describe the figures as well as the internal data structure for representing them, Peabody is a language with a powerful and flexible mechanism for representing connectivity between objects, both the joints between individual segments within a figure and arbitrary connections between different figures. Peabody objects are generally comprised of several individual figures, each one a collection of segments. Each segment has a geometry represented by PSURF files that consist of polygons or curved surface patches. Although JACK does not have the capability to create new objects, objects may be created by other geometric modeling programs and then translated into the PSURF format. Environment files are a collection of figures and attributes that may be dynamically moved under the control of an animation file. The animation facilities allow the user to create a sequence of commands that duplicate the movements of a

    2015-01-01

    Among the technologies used to recuperate cadmium (Cd) contaminated soils, phytoextraction are particularly important, where the selection of suitable plants is critical to the success of the soil remediation. Thus, the objectives of this study were to evaluate the responses of jack-bean and sorghum to Cd supply and to quantify Cd accumulation by these species grown in hydroponic culture. The plants were subjected to 0, 15, 30, or 60 μmol Cd L(-1) in the nutrient solution, and gas exchange, plant growth and Cd accumulation were measured at 25 days after starting Cd treatments. The Cd supply severely reduced growth of shoots and roots in both species. In jack-bean, Cd decreased photosynthesis by 56-86%, stomatal conductance by 59-85% and transpiration by 48-80%. The concentrations and amounts of Cd accumulated in the plant tissues were proportional to the metal supply in the nutrient solution. Sorghum was more tolerant than jack-bean to Cd toxicity, but the latter showed a greater metal concentration and accumulation in the shoot. Therefore, jack-bean would be more suitable than sorghum for use in Cd phytoremediation programs based on phytoextraction.

  19. Jacking mechanism for upper internals structure of a liquid metal nuclear reactor

    International Nuclear Information System (INIS)

    Gillett, J.E.; Wineman, A.L.

    1984-01-01

    A jacking mechanism is described for raising the upper internals structure of a liquid metal nuclear reactor which jacking mechanism uses a system of gears and drive shafts to transmit force from a single motor to four mechanically synchronized ball jacks to raise and lower support columns which support the upper internals structure. The support columns have a pin structure which rides up and down in a slot in a housing fixed to the reactor head. The pin has two locking plates which can be rotated around the pin to bring bolt holes through the locking plates into alignment with a set of bolt holes in the housing, there being a set of such housing bolt holes corresponding to both a raised and a lowered position of the support column. When the locking plate is so aligned, a surface of the locking plate mates with a surface in the housing such that the support column is then supported by the locking plate and not by the ball jacks. Since the locking plates are to be installed and bolted to the housing during periods of reactor operation, the ball jacks need not be sized to react the large forces which occur or potentially could occur on the upper internals structure of the reactor during operation. The locking plates react these loads. The ball jacks, used only during refueling, can be smaller, which enable conventionally available equipment to fulfill the precision requirements for the task within available space

  2. Gender and morals in Spanish Catholic youth culture: a case study of the Marian Congregations 1930-1936.

    Science.gov (United States)

    Vincent, M

    2001-01-01

    Jesuit-run Marian Congregations proliferated in 1930s Spain. Drawing on literature produced for their members, this article demonstrates how gendered understandings were fundamental to the congregations' symbolic delineation of an uncontaminated Catholic space. Visions of an incorrupt male elite abound, reinforcing the Jesuits' educational mission among future leaders and opinion-formers. In contrast, the purity of women and children was seen as a sign of society's moral health. Modesty was the quintessential female virtue. Yet, the cult of the Virgin Mary suggested that the virginal female body was both tool and symbol in the struggle against a fallen world. Girls were, therefore, charged with the task of moral guardianship. Such campaigns were emblematic of Spanish Catholicism's tendency to proffer religious solutions to social problems.

  4. De-metaphorizing and becoming animal: when the animal looks back. A reading of Marian Engel’s Bear = Desmetaforizando e tornando-se animal: quando o animal retorna o olhar. Uma leitura do romance Bear, de Marian Engel

    Directory of Open Access Journals (Sweden)

    Alessandra Meoni

    2011-01-01

    Full Text Available The primacy acquired by nature in our current culture has given way to several issues not strictly connected with an immediate and ‘purely’ ecological interest: there is rather the need to question how we conceive the animal with a focus on the possibility to transcend Western cultural heritage. When trying to give a literary representation of the animal, it is particularly important to adopt some measures which, following the trajectory of a genuine, positive ‘becoming-animal’, will safeguard its independence and avoid reducing it to metaphorically anthropomorphic representations. This essay intends to underline how, from this viewpoint, a few novels coming from the post-colonial area, where animal tales often show how interwoven humans and animals are and how they are constructed in relation to each other supply interesting case studies. My interest focuses particularly on Canadian Marian Engel’s Bear, where the writer tries to deal with unspeakable subjects between a woman and a bear: through an act of radical approach to its physical reality, the former comes first to recognize the latter, and then to accept its Otherness. On its side, the bear seemingly ‘shows’ a post-colonial attitude subversively resisting a typically Western anthropomorphic allegorization. Holding fast to itself and its animality, choosing in a way to ‘stay mute’, the bear keeps the role of a ‘perceptivecatalyst’, ‘thought-producing’ and thus ‘world-changing’, according to an aesthetics of perception suggesting that the animal gaze might be the best perspective from which to observe not only our world, but especially our own selves.Uma leitura do romance Bear, de Marian Engel.

  5. An Analytical Method for Jack-Up Riser’s Fatigue Life Estimation

    2018-01-01

    Full Text Available In order to determine whether a special sea area and its sea state are available for the jack-up riser with surface blowout preventers, an analytical method is presented to estimate the jack-up riser’s wave loading fatigue life in this study. In addition, an approximate formula is derived to compute the random wave force spectrum of the small-scale structures. The results show that the response of jack-up riser is a narrow band random vibration. The infinite water depth dispersion relation between wavenumber and wave frequency can be used to calculate the wave force spectrum of small-scale structures. The riser’s response mainly consists of the additional displacement response. The fatigue life obtained by the formula proposed by Steinberg is less than that of the Bendat method.

The ninth volume deal witch the invocations found in Bahia. In this article we mean to use this text as a study sourse for the history religious belief, as well as in the study of the Catholic religiosity history among the black people in the reconcavo baiano. The reconcavo baiano was one of the most important region of the sugar cane production in the American Portuguesa in that period where concentrated an expressive population of black people that was used in the slave labor in that production. Our analysis which has as a main objective of study Our Lady of Rosario worship in the brotherhoods and the black people’s devotions in that region. Seeking to understand at first the motivation for such worship, experienced in the context of the slavery. Subsequently we will concentrate our analysis in the aspects linked to its growth and development, such as celebrations for their Patroness, and the use of images in moments of celebrations. From here it’s necessary to comprehend how the place of the black, as a slave or a free man, marked the relations established and the differents moments of celebrations.

  8. Topological color codes on Union Jack lattices: a stable implementation of the whole Clifford group

    2010-01-01

    We study the error threshold of topological color codes on Union Jack lattices that allow for the full implementation of the whole Clifford group of quantum gates. After mapping the error-correction process onto a statistical mechanical random three-body Ising model on a Union Jack lattice, we compute its phase diagram in the temperature-disorder plane using Monte Carlo simulations. Surprisingly, topological color codes on Union Jack lattices have a similar error stability to color codes on triangular lattices, as well as to the Kitaev toric code. The enhanced computational capabilities of the topological color codes on Union Jack lattices with respect to triangular lattices and the toric code combined with the inherent robustness of this implementation show good prospects for future stable quantum computer implementations.

    The SpyJack Remote Monitoring System, a stand-alone, single-site remote well monitoring system that works off its own embedded controller is described. The supervisory control and data acquisition (SCADA) unit, developed by CORE Technologies Inc., has an integrated voice/alarm system, monitoring sensors installed at remote well sites continuously 24 hours a day with a digital camera, with 300 degrees of visual confirmation capability. It can also be used as a surveillance tool against terrorism as has been shown in the case of some recent debilitating attacks on remote wells in Alberta. SpyJack monitors flow rates and pressures, pumpjack stroke rates, sucker rod temperature, load cell and engine shut-off relay, as well as ambient temperature, tank levels, and motion detection. At the office, SpyJack Well Management Interface uses nine drop-down screens to take users through the remote monitoring and control of each site. The screens include production sensors, line sensors, dyno chart, environmental/safety sensors and sensor information and set up. Currently under development is the unsolicited dial-out capability. When implemented the system will send out information at pre-determined times, such as every four hours, or at specific times during the day. Compressing images to enable speedier downloading is also being planned

  10. An experimental study of the mechanism of failure of rocks under borehole jack loading

    Van, T. K.; Goodman, R. E.

    1971-01-01

    Laboratory and field tests with an experimental jack and an NX-borehole jack are reported. The following conclusions were made: Under borehole jack loading, a circular opening in a brittle solid fails by tensile fracturing when the bearing plate width is not too small. Two proposed contact stress distributions can explain the mechanism of tensile fracturing. The contact stress distribution factor is a material property which can be determined experimentally. The borehole tensile strength is larger than the rupture flexural strength. Knowing the magnitude and orientation of the in situ stress field, borehole jack test results can be used to determine the borehole tensile strength. Knowing the orientation of the in situ stress field and the flexural strength of the rock substance, the magnitude of the in situ stress components can be calculated. The detection of very small cracks is essential for the accurate determination of the failure loads which are used in the calculation of strengths and stress components.

  13. Spin-singlet quantum Hall states and Jack polynomials with a prescribed symmetry

    Estienne, Benoit; Bernevig, B. Andrei

    2012-01-01

    We show that a large class of bosonic spin-singlet Fractional Quantum Hall model wavefunctions and their quasihole excitations can be written in terms of Jack polynomials with a prescribed symmetry. Our approach describes new spin-singlet quantum Hall states at filling fraction ν=(2k)/(2r-1) and generalizes the (k,r) spin-polarized Jack polynomial states. The NASS and Halperin spin-singlet states emerge as specific cases of our construction. The polynomials express many-body states which contain configurations obtained from a root partition through a generalized squeezing procedure involving spin and orbital degrees of freedom. The corresponding generalized Pauli principle for root partitions is obtained, allowing for counting of the quasihole states. We also extract the central charge and quasihole scaling dimension, and propose a conjecture for the underlying CFT of the (k,r) spin-singlet Jack states.

  19. Jack Polynomials as Fractional Quantum Hall States and the Betti Numbers of the ( k + 1)-Equals Ideal

    Science.gov (United States)

    Zamaere, Christine Berkesch; Griffeth, Stephen; Sam, Steven V.

    2014-08-01

    We show that for Jack parameter α = -( k + 1)/( r - 1), certain Jack polynomials studied by Feigin-Jimbo-Miwa-Mukhin vanish to order r when k + 1 of the coordinates coincide. This result was conjectured by Bernevig and Haldane, who proposed that these Jack polynomials are model wavefunctions for fractional quantum Hall states. Special cases of these Jack polynomials include the wavefunctions of Laughlin and Read-Rezayi. In fact, along these lines we prove several vanishing theorems known as clustering properties for Jack polynomials in the mathematical physics literature, special cases of which had previously been conjectured by Bernevig and Haldane. Motivated by the method of proof, which in the case r = 2 identifies the span of the relevant Jack polynomials with the S n -invariant part of a unitary representation of the rational Cherednik algebra, we conjecture that unitary representations of the type A Cherednik algebra have graded minimal free resolutions of Bernstein-Gelfand-Gelfand type; we prove this for the ideal of the ( k + 1)-equals arrangement in the case when the number of coordinates n is at most 2 k + 1. In general, our conjecture predicts the graded S n -equivariant Betti numbers of the ideal of the ( k + 1)-equals arrangement with no restriction on the number of ambient dimensions.

  20. The Jack Wills crowd: towards a sociology of an elite subculture.

    2018-03-01

    British sociologists have long been interested in youth sub-cultures. However British sociologists have tended to focus on working class subcultures and avoided engagement with exclusive sub-cultures of elite social groups. This article seeks to attend to this gap by examining the subculture of a British elite: ex-public school students at select universities in the UK in the twenty-first century. This group consists of a relatively small group of young adults, aged between 18 and 23, who attended public schools, especially one of the nine Clarendon schools (Eton, Winchester, Westminster, St. Paul's, Merchant Taylor's, Shrewsbury, Rugby, Harrow and Charterhouse), and were students at a selective group of British universities, primarily Oxford and Cambridge, Durham, Bristol, Exeter, Bath, Manchester, St Andrews and Edinburgh. The article examines the way in which this group has reconfigured and re-constituted itself in the face of globalizing challenges. Specifically, it examines the way in which participation of ex-public school students in events run by and under the patronage of the high street retailing company, Jack Wills, has played a galvanising role for this group in the last decade. The Jack Wills crowd is an example of how some young adults form exclusive social networks and reproduce prevailing forms of privilege. The social networks built around the Jack Wills subculture is likely to provide them with advantages in the job market through a prodigious network of connections and patrons. The Jack Wills subculture potentially contributions to the socio-economic reproduction of the higher professional middle classes. © London School of Economics and Political Science 2017.

    The lateral jack-knife position is often used during transpsoas surgery to improve access to the spine. Postoperative neurological signs and symptoms are very common after such procedures, and the mechanism is not adequately understood. The objective of this study is to assess if the lateral jack-knife position alone can cause neurapraxia. This study compares neurological status at baseline and after positioning in the 25° right lateral jack-knife (RLJK) and the right lateral decubitus (RLD) position. Fifty healthy volunteers, ages 21 to 35, were randomly assigned to one of 2 groups: Group A (RLD) and Group B (RLJK). Motor and sensory testing was performed prior to positioning. Subjects were placed in the RLD or RLJK position, according to group assignment, for 60 minutes. Motor testing was performed immediately after this 60-minute period and again 60 minutes thereafter. Sensory testing was performed immediately after the 60-minute period and every 15 minutes thereafter, for a total of 5 times. Motor testing was performed by a physical therapist who was blinded to group assignment. A follow-up call was made 7 days after the positioning sessions. Motor deficits were observed in the nondependent lower limb in 100% of the subjects in Group B, and no motor deficits were seen in Group A. Statistically significant differences (p knife positioning for 60 minutes results in neurapraxia of the nondependent lower extremity. Our results support the hypothesis that jack-knife positioning alone can cause postoperative neurological symptoms.

    2006-04-28

    John T. (Jack) Reeves' science is reviewed across the 37 years of his research career at the University of Colorado Health Sciences Center, a period which occupied approximately half his remarkable life. His contributions centered on understanding the inter-relatedness as well as the underlying mechanisms controlling the various components of the O(2) transport system. We review here his studies on exercise performance; these encompassed about half his scientific output with the other half being devoted to the study of hypoxic pulmonary hypertension. Early studies concerned cardiac output, showing how it was a balance between O(2) uptake and O(2) extraction, and that cardiac output during exercise at high altitude was reduced, most likely because of decreased plasma volume and left ventricular filling. Jack's many studies addressed virtually every aspect of the O(2) transport system -- adding significantly to our understanding of the syndromes of altitude illness, the mechanisms by which ventilatory sensitivity to hypoxia and hypercapnia influenced ventilatory acclimatization, and the contributions of the various limbs of the autonomic nervous system on systemic blood pressure, vascular resistance and substrate utilization. His scientific career ended abruptly in 2004 when struck by a car while biking to work, but his legacy remains in his more than 385+ research articles or chapters, the 40+ fellows he trained, and the countless number of younger (and older) scientists for whom he served as a role model for learning how to scrutinize their data and present their findings in clear and sometimes bold prose. An integral man, he is sorely missed.

    In situ Li analyses of 4348 to 3362 Ma detrital zircons from the Jack Hills, Western Australia by SIMS reveal that the Li abundances (typically 10 to 60 ppm) are commonly over 10,000 times higher than in zircons crystallized from mantle-derived magmas and in mantle-derived zircon megacrysts (typically Jack Hills zircons also have fractionated lithium isotope ratios ( δ7Li = - 19 to + 13‰) about five times more variable than those recorded in primitive ocean floor basalts (2 to 8‰), but similar to continental crust and its weathering products. Values of δ7Li below - 10‰ are found in zircons that formed as early as 4300 Ma. The high Li compositions indicate that primitive magmas were not the source of Jack Hills zircons and the fractionated values of δ7Li suggest that highly weathered regolith was sampled by these early Archean magmas. These new Li data provide evidence that the parent magmas of ancient zircons from Jack Hills incorporated materials from the surface of the Earth that interacted at low temperature with liquid water. These data support the hypothesis that continental-type crust and oceans existed by 4300 Ma, within 250 million years of the formation of Earth and the low values of δ7Li suggest that weathering was extensive in the early Archean.

    Jack bean urease was purified and crystallized and X-ray diffraction data were collected to 2.05 Å resolution. Plant urease is a seed protein that is common in most legumes. It is also common in many bacteria and fungi and several species of yeast. Urease allows organisms to use exogenous and internally generated urea as a nitrogen source by catalyzing the hydrolysis of urea to ammonia and carbon dioxide. Urease from jack bean meal was purified to electrophoretic homogeneity using a series of steps involving acetone precipitation and size-exclusion and ion-exchange chromatography.

    2017-11-01

    The cutting off column and jacking technology is a method for increasing story height, which has been widely used and paid much attention in engineering. The stiffness will be changed after the process of cutting off column and jacking, which directly affects the overall seismic performance. It is usually necessary to take seismic strengthening measures to enhance the stiffness. A five story frame structure jacking project in Jinan High-tech Zone was taken as an example, and three finite element models were established which contains the frame model before lifting, after lifting and after strengthening. Based on the stiffness, the dynamic time-history analysis was carried out to research its seismic performance under the EL-Centro seismic wave, the Taft seismic wave and the Tianjin artificial seismic wave. The research can provide some guidance for the design and construction of the entire jack lifting structure.

    Bassam M. Al-Shraah

    2017-11-01

    Full Text Available This paper aims to sketch out the transformation that Jack Burden—the main character in the novel—had gone through. With all the political leanings in Warren’s All the king’s Men, Jack burden seems to have had developed his own theories of dealing with life and people all through his life. He has always suffered an inferiority complex, rendering himself unworthy of being a real human being. This paper claims that Jack’s philosophical transformation has passed through three distinct phases; he had changed from a carefree idealist to a man of moral responsibility much similar to a Bildungsroman style of character maturation. Difficult times that Jack Burden has gone through caused his awakening at the end of the novel ushering his maturation

    Graphical abstract: -- Abstract: Highly branched, jacks-like ZnO nanorods architecture were explored as a photoanode in dye-sensitized solar cells, and their photovoltaic performance was compared with that of branch-free ZnO nanorods photoanodes. The highly branched network and large pores of the jacks-like ZnO nanorods electrodes enhances the charge transport, and electrolyte penetration. Thus, the jacks-like ZnO nanorods DSSCs render a higher conversion efficiency of η = 1.82% (V oc = 0.59 V, J sc = 5.52 mA cm -2 ) than that of the branch-free ZnO nanorods electrodes (η = 1.08%, V oc = 0.49 V, J sc = 4.02 mA cm -2 ). The incident photon-to-current conversion efficiency measurements reveal that the jacks-like ZnO nanorods DSSCs exhibit higher internal quantum efficiency (∼59.1%) than do the branch-free ZnO nanorods DSSC (∼52.5%). The charge transfer resistances at the ZnO/dye/electrolyte interfaces investigated using electrochemical impedance spectroscopy showed that the jacks-like ZnO nanorods DSSC had high charge transfer resistance and a slightly longer electron lifetime, thus improving the solar-cell performance.

    The effect of four cooking methods was evaluated for proximate composition, fatty acid, calcium, iron, and zinc content in salmon and Chilean jack mackerel. The moisture content of steamed salmon decreased (64.94%) compared to the control (68.05%); a significant decrease was observed in Chilean jack mackerel in all the treatments when compared to the control (75.37%). Protein content in both salmon and Chilean jack mackerel significantly increased under the different treatments while the most significant decrease in lipids was found in oven cooking and canning for salmon and microwaving for Chilean jack mackerel. Ash concentration in both salmon and Chilean jack mackerel did not reveal any significant differences. Iron and calcium content only had significant changes in steaming while zinc did not undergo any significant changes in the different treatments. Finally, no drastic changes were observed in the fatty acid profile in both salmon and Chilean jack mackerel. PMID:28686742

  7. Lithogenic and biogenic particle deposition in an Antarctic coastal environment (Marian Cove, King George Island): Seasonal patterns from a sediment trap study

    Particulate suspended material was recovered over a 23-month period using two sediment traps deployed in shallow water (˜30 m deep) off the King Sejong Station located in Marian Cove of King George Island, West Antarctica. Variability in seasonal flux and geochemical characteristics of the sediment particles highlights seasonal patterns of sedimentation of both lithogenic (terrigenous) and biogenic particles in the coastal glaciomarine environment. All components including total mass flux, lithogenic particle flux and biogenic particle flux show distinct seasonal variation, with high recovery rates during the summer and low rates under winter fast ice. The major contributor to total mass flux is the lithogenic component, comprising from 88% during the summer months (about 21 g m -2 d -1) up to 97% during the winter season (about 2 g m -2 d -1). The lithogenic particle flux depends mainly on the amount of snow-melt (snow accumulation) delivered into the coastal region as well as on the resuspension of sedimentary materials. These fine-grained lithogenic particles are silt-to-clay sized, composed mostly of clay minerals weathered on King George Island. Biogenic particle flux is also seasonal. Winter flux is ˜0.2 g m -2 d -1, whereas the summer contribution increases more than tenfold, up to 2.6 g m -2 d -1. Different biogenic flux between the two summers indicates inter-annual variability to the spring-summer phytoplankton bloom. The maximum of lithogenic particle flux occurs over a short period of time, and follows the peak of biogenic particle flux, which lasts longer. The seasonal warming and sea-ice retreat result in change in seawater nutrient status and subsequent ice-edge phytoplankton production. Meanwhile, the meltwater input to Marian Cove from the coastal drainage in January to February plays a major role in transporting lithogenic particles into the shallow water environment, although the tidal currents may be the main agents of resuspension in this

    2018-04-01

    This study evaluated failure probabilities of jack up units on the framework of time dependent reliability analysis using uncertainty from different sea states representing different return period of the design wave. Surface elevation for each sea state was represented by Karhunen-Loeve expansion method using the eigenfunctions of prolate spheroidal wave functions in order to obtain the wave load. The stochastic wave load was propagated on a simplified jack up model developed in commercial software to obtain the structural response due to the wave loading. Analysis of the stochastic response to determine the failure probability in excessive deck displacement in the framework of time dependent reliability analysis was performed by developing Matlab codes in a personal computer. Results from the study indicated that the failure probability increases with increase in the severity of the sea state representing a longer return period. Although the results obtained are in agreement with the results of a study of similar jack up model using time independent method at higher values of maximum allowable deck displacement, it is in contrast at lower values of the criteria where the study reported that failure probability decreases with increase in the severity of the sea state.

    2002-06-01

    We studied the population structure of a lodgepole (Pinus contorta Dougl.) and jack pine (Pinus banksiana Lamb.) complex in west central Alberta and neighboring areas by assessing random amplified polymorphic DNA (RAPD) variability in 23 lodgepole pine, 9 jack pine, and 8 putative hybrid populations. Of 200 random primers screened, 10 that amplified 39 sharp and reproducible RAPDs were chosen for the study. None of the 39 RAPDs were unique to the parental species. RAPD diversity ranged from 0.085 to 0.190 among populations and averaged 0.143 for lodgepole pine, 0.156 for jack pine, 0.152 for hybrids, and 0.148 for all 40 populations. The estimated population differentiation based on G(ST) was 0.168 for hybrids, 0.162 for lodgepole pine, 0.155 for jack pine, and 0.247 across all 40 populations. Cluster analysis of genetic distances generally separated jack pine from lodgepole pine and hybrids, but no division could be identified that further separated lodgepole pine from hybrids. The observed weak to mild trend of "introgression by distance" in the complex and neighbouring areas was consistent with the view that introgressive hybridization between lodgepole and jack pines within and outside the hybrid zone may have been through secondary contact and primary intergradation, respectively.

    Sharing one's own immersive experience over the Internet is one of the ultimate goals of telepresence technology. In this paper, we present JackIn Head, a visual telepresence system featuring an omnidirectional wearable camera with image motion stabilization. Spherical omnidirectional video footage taken around the head of a local user is stabilized and then broadcast to others, allowing remote users to explore the immersive visual environment independently of the local user's head direction. We describe the system design of JackIn Head and report the evaluation results of real-time image stabilization and alleviation of cybersickness. Then, through an exploratory observation study, we investigate how individuals can remotely interact, communicate with, and assist each other with our system. We report our observation and analysis of inter-personal communication, demonstrating the effectiveness of our system in augmenting remote collaboration.

    In the history of Christianity, veneration of the Virgin Mary reached its greatest intensity in the XIII century. Her perceived impact on daily life was tremendous and not surprisingly this extended to the spheres of disease and healing. The purpose of this study is to compare the medical and neuropsychiatric findings in two XIII century Spanish texts of Marian miracles, both examples of the popular Catholicism (vs. official catholic doctrine). We analyzed the medical and neuropsychiatric events in the Cantigas de Santa Maria (Canticles of St. Mary, CSM), composed at the court of Alfonso X and the Milagros de Nuestra Señora (The Miracles of Our Lady, MNS), written by Gonzalo de Berceo. Among the 25 miracles reported in the MNS, medically relevant facts were addressed in 19 miracles with a total of 23 recorded events (including resurrection or escape from death in five) and demonic possession in three (one with witchcraft/deicide). The most common medical subjects were ergotism, obstetric-gynecological, sudden death, intellectual disability/illiteracy, encephalopathy/alcohol intoxication, suicide (with self-mutilation/castration), infanticide, infections, and absence of body decomposition after death. The 427 canticles in the CSM contain 270 medically relevant facts. Neuropsychiatric conditions were alluded to in 98 songs. Blindness and dystonia/weakness/deformities were the most common phenomena. Illuminations detailed many of the medical facts in the CSM, but not in the MNS. Medically relevant facts were described in both texts, but with more details in the CSM. Neurological conditions were more often described in the CSM, psychiatric conditions in the MNS.

    The aim of this study was to analyze the relationships between the head-out aquatic exercise "Jumping jacks" kinematics and the musical cadence in healthy and fit subjects. Five young women, with at least one year of experience conducting head- out aquatic programs were videotaped in the frontal plane, with a pair of cameras providing a double projection (above and below the water surface). Subjects performed an incremental protocol of five bouts (120 b·min(-1), 135 b·min(-1), 150 b·min(-1), 165 b·min(-1) and 180 b·min(-1)) with 16 full cycles of the "Jumping jacks" exercise. Data processing and calculation of upper limbs' (i.e. hands), lower limbs' (i.e. feet) and center of mass' 2D linear velocity and displacement were computed with the software Ariel Performance Analysis System and applying the 2D-DLT algorithm. Subjects decreased the cycle period during the incremental protocol. Significant and negative relationships with the musical cadence were verified for the center of mass and upper limbs vertical displacement. On the other hand, for the lower limbs lateral velocity, a significant and positive relationship was observed. It is concluded that expert and fit subjects increase the lower limb's velocity to maintain the range of motion, while the upper limb's displacement is reduced to coupe the music cadence. Key pointsWhile performing the Jumping Jacks, expert and fit subjects increase their lower limbs segmental velocity to maintain the range of motion.The upper limbs displacement is reduced to maintain the music cadence.Expert and fit subjects present similar response for alternating or simultaneously head-out aquatic exercises when increasing the music cadence.

    Metasediments of the Jack Hills contain the oldest known terrestrial minerals in the form of zircons nearly 4.4 billion years old. Paleointensity data from these zircons provide evidence for a Hadean geodynamo as old as 4.2 billion years old. Given the importance of these zircons for constraining the earliest history of the core, it is vital to understand the fidelity of the zircon record. A fundamental aspect providing context for the preservation of primary magnetic signals is the nature of overprints predicted to have been imparted on rocks of the Jack Hills due to Archean to Proterozoic metamorphic events. To be viable magnetic records of a Hadean geodynamo, zircon magnetization directions should differ from these secondary magnetizations. To evaluate these secondary magnetizations, we report paleomagnetic analyses of a comprehensive sampling of 68 quartzite cobble-sized clasts from the Jack Hills metasediments ∼0.5 to 1.0 km from the Discovery Site (which has yielded the oldest zircons and paleofield estimates). While application of standard paleomagnetic tests suggests that the ensemble of cobble directions cannot be distinguished from those drawn from a random distribution, a new cluster analysis of directions on a sphere and non-parametric resampling approaches reveal significant directions amongst subsets of the data. One, isolated at the lowest temperature analyzed [200 to 300 °C, Declination (Dec.) = 316.8°, Inclination (Inc.) = - 51.1 °] appears to be dominated by the present day field. Another, isolated at higher (but still relatively low unblocking temperatures that we call "intermediate", of ∼350-500 °C, Dec. = 243.8°, Inc. = 9.5°) agrees with a magnetic overprint isolated from the secondary Cr-Fe mica fuchsite isolated from the Jack Hills Discovery site, passing a field test at the 80% confidence level. No evidence is found in our data, or in the data of others collected on similar Jack Hills lithologies, for a widespread 1 Ga

    Full Text Available The mountain pine beetle (MPB; Dendroctonus ponderosae has recently expanded its range from lodgepole pine forest into the lodgepole × jack pine hybrid zone in central Alberta, within which it has attacked pure jack pine. This study tested the effects of water limitation on tree defense response of mature lodgepole and jack pine (Pinus contorta and Pinus banksiana trees in the field. Tree defense response was initiated by inoculation of trees with the MPB-associated fungus Grosmannia clavigera and measured through monoterpene emission from tree boles and concentration of defensive compounds in phloem, needles, and necrotic tissues. Lodgepole pine generally emitted higher amounts of monoterpenes than jack pine; particularly from fungal-inoculated trees. Compared to non-inoculated trees, fungal inoculation increased monoterpene emission in both species, whereas water treatment had no effect on monoterpene emission. The phloem of both pine species contains (--α-pinene, the precursor of the beetle’s aggregation pheromone, however lodgepole pine contains two times as much as jack pine. The concentration of defensive compounds was 70-fold greater in the lesion tissue in jack pine, but only 10-fold in lodgepole pine compared to healthy phloem tissue in each species, respectively. Water-deficit treatment inhibited an increase of L-limonene as response to fungal inoculation in lodgepole pine phloem. The amount of myrcene in jack pine phloem was higher in water-deficit trees compared to ambient trees. Beetles reared in jack pine were not affected by either water or biological treatment, whereas beetles reared in lodgepole pine benefited from fungal inoculation by producing larger and heavier female offspring. Female beetles that emerged from jack pine bolts contained more fat than those that emerged from lodgepole pine, even though lodgepole pine phloem had a higher nitrogen content than jack pine phloem. These results suggest that jack pine chemistry

    Full Text Available Adequate soil management can create favorable conditions to reduce erosion and water runoff, consequently increase water soil recharge. Among management systems intercropping is highly used, especially for medium and small farmers. It is a system where two or more crops with different architectures and vegetative cycles are explored simultaneously at the same location. This research investigated the effects of maize intercropped with jack bean on soil losses due to water erosion, estimate C factor of Universal Soil Losses Equation (USLE and how it can be affected by soil coverage. The results obtained also contribute to database generation, important to model and estimate soil erosion. Total soil loss by erosion caused by natural rain, at Lavras, Minas Gerais, Brazil, were: 4.20, 1.86, 1.38 and 1.14 Mg ha-1, respectively, for bare soil, maize, jack bean and the intercropping of both species, during evaluated period. Values of C factor of USLE were: 0.039, 0.054 and 0.077 Mg ha Mg-1 ha-1 for maize, jack bean and intercropping between both crops, respectively. Maize presented lower vegetation cover index, followed by jack beans and consortium of the studied species. Intercropping between species showed greater potential on soil erosion control, since its cultivation resulted in lower soil losses than single crops cultivation, and this aspect is really important for small and medium farmers in the studied region.

  20. Comparison of lodgepole and jack pine resin chemistry: implications for range expansion by the mountain pine beetle, Dendroctonus ponderosae (Coleoptera: Curculionidae

    Full Text Available The mountain pine beetle, Dendroctonus ponderosae, is a significant pest of lodgepole pine in British Columbia (BC, where it has recently reached an unprecedented outbreak level. Although it is native to western North America, the beetle can now be viewed as a native invasive because for the first time in recorded history it has begun to reproduce in native jack pine stands within the North American boreal forest. The ability of jack pine trees to defend themselves against mass attack and their suitability for brood success will play a major role in the success of this insect in a putatively new geographic range and host. Lodgepole and jack pine were sampled along a transect extending from the beetle’s historic range (central BC to the newly invaded area east of the Rocky Mountains in north-central Alberta (AB in Canada for constitutive phloem resin terpene levels. In addition, two populations of lodgepole pine (BC and one population of jack pine (AB were sampled for levels of induced phloem terpenes. Phloem resin terpenes were identified and quantified using gas chromatography. Significant differences were found in constitutive levels of terpenes between the two species of pine. Constitutive α-pinene levels – a precursor in the biosynthesis of components of the aggregation and antiaggregation pheromones of mountain pine beetle – were significantly higher in jack pine. However, lower constitutive levels of compounds known to be toxic to bark beetles, e.g., 3-carene, in jack pine suggests that this species could be poorly defended. Differences in wounding-induced responses for phloem accumulation of five major terpenes were found between the two populations of lodgepole pine and between lodgepole and jack pine. The mountain pine beetle will face a different constitutive and induced phloem resin terpene environment when locating and colonizing jack pine in its new geographic range, and this may play a significant role in the ability of the

    2015-05-01

    Full Text Available The secondary compounds of pines (Pinus can strongly affect the physiology, ecology and behaviors of the bark beetles (Coleoptera: Curculionidae, Scolytinae that feed on sub-cortical tissues of hosts. Jack pine (Pinus banksiana has a wide natural distribution range in North America (Canada and USA and thus variations in its secondary compounds, particularly monoterpenes, could affect the host expansion of invasive mountain pine beetle (Dendroctonus ponderosae, which has recently expanded its range into the novel jack pine boreal forest. We investigated monoterpene composition of 601 jack pine trees from natural and provenance forest stands representing 63 populations from Alberta to the Atlantic coast. Throughout its range, jack pine exhibited three chemotypes characterized by high proportions of α-pinene, β-pinene, or limonene. The frequency with which the α-pinene and β-pinene chemotypes occurred at individual sites was correlated to climatic variables, such as continentality and mean annual precipitation, as were the individual α-pinene and β-pinene concentrations. However, other monoterpenes were generally not correlated to climatic variables or geographic distribution. Finally, while the enantiomeric ratios of β-pinene and limonene remained constant across jack pine’s distribution, (‒:(+-α-pinene exhibited two separate trends, thereby delineating two α-pinene phenotypes, both of which occurred across jack pine’s range. These significant variations in jack pine monoterpene composition may have cascading effects on the continued eastward spread and success of D. ponderosae in the Canadian boreal forest.

    Recently, Aker Solutions delivered a movable chain jack system to PETROBRAS's P58/P62 FPSOs and a movable windlass system to ENI's Goliat FPSO. This paper highlights the main differences between the two systems and when it is beneficial to employ movable systems. There are many parameters to consider in determining which system to use - also a traditional system involving a single winch or chain jack per mooring line may in many cases be preferred. The movable chain jack concept is designed to operate multiple mooring lines within the same cluster. A single chain jack is lifted by a skidding gantry and moved to the next mooring line and so forth. Installation and messenger chains are moved using a large sliding chain locker allowing for later offloading of the surplus chain. The movable windlass system is also designed to operate multiple mooring lines within the same cluster. However, in this case the winch is rotary and can operate via electric or hydraulic power. One of the main considerations is to move the windlass and keep the mooring lines intact without cutting them. (author)

    When a disaster is so huge like Kobe earthquake, every energy line is killed. Even if we want to help the sufferers, we have no energy to move machines to help them. As collapsed houses are very heavy, we need machines to remove collapsed stuff. Explosives include a lot of energy in themselves. So, an air-jack which has explosives inside was developed to remove collapsed stuff on suffered people. A simple air-jack was made and tested. One concrete block, 50cm x 50cm x 50cm, was lifted by the simple air-jack. A simulation of lifting the concrete block was carried out with a programme ANSYS on the super computer. (author)

    The main objective of this study was to assess the influence of slaughter methods on the quality of Chilean jack mackerel (Trachurus murphyi) during refrigerated storage on board. Fishes were slaughtered by asphyxia in air (AA), asphyxia in ice water (AI) or stunning fish heads (SH), and the rigor mortis, pH, total volatile basic nitrogen (TVB-N), trimethylamine (TMA), 2-thiobarbituric acid reactive substances (TBARS) and sensory properties for the fishes were analyzed. On day 0, Chilean jack mackerel samples of AI group displayed higher pH values than those of AA and SH groups. TVB-N, TMA and TBARS values of all samples increased with the storage time, and these values of AI had a lower increase than AA and SH. Moreover, samples of AI had a better sensory score than AA and SH during storage. It can be concluded that slaughter method of asphyxia in ice water for Chilean jack mackerel exhibit the better efficiency on maintaining the fish quality during refrigerated storage on board.

    Overlapping decapeptide fragments of H. pylori urease subunit A (UreA) were synthesized and tested with polyclonal antibodies against Canavalia ensiformis (Jack bean) urease. The linear epitopes of UreA identified using the dot blot method were then examined using epitope mapping. For this purpose, series of overlapping fragments of UreA, frameshifted ± four amino acid residues were synthesized. Most of the UreA epitopes which reacted with the Jack bean urease polyclonal antibodies had been recognized in previous studies by monoclonal antibodies against H. pylori urease. Fragments 11 - 24, 21 - 33, and 31 - 42 were able to interact with the Jack bean urease antibodies, giving stable immunological complexes. However, the lack of recognition by these antibodies of all the components in the peptide map strongly suggests that a non-continuous (nonlinear) epitope is located on the N-terminal domain of UreA. © 2018 Wiley-VHCA AG, Zurich, Switzerland.

    Acid deposition may adversely affect northern forest ecosystems by increasing the concentration of metals in the soil solution. This study investigates the effects of ectomycorrhizal fungi on paper birch and jack pine seedlings exposed to elevated Cu, Ni or Al in sand culture. One of four mycorrhizal fungi, Scleroderma flavidum, was able to reduce Ni toxicity to the birch seedlings. It did this by reducing transport of Ni to the stems. None of the fungi affected Cu toxicity in birch. In separate experiments, jack pine seedlings were exposed to combinations of Al and Ca. Infection with Rhizopogon rubescens increased seedling susceptibility to Al. Seedlings inoculated with Suillus tomentosus showed a greater growth stimulation by Ca than uninoculated jack pines. Thus, for both tree species, the mycorrhizal association could alter the response of seedlings to high concentrations of certain metals, although this varied with fungal species. 8 references.

    Understanding the physical and genetic structure of hybrid zones can illuminate factors affecting their formation and stability. In north-central Alberta, lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia) and jack pine (Pinus banksiana Lamb) form a complex and poorly defined hybrid zone. Better knowledge of this zone is relevant, given the recent host expansion of mountain pine beetle into jack pine. We characterized the zone by genotyping 1998 lodgepole, jack pine, and hybrids from British Columbia, Alberta, Saskatchewan, Ontario, and Minnesota at 11 microsatellites. Using Bayesian algorithms, we calculated genetic ancestry and used this to model the relationship between species occurrence and environment. In addition, we analyzed the ancestry of hybrids to calculate the genetic contribution of lodgepole and jack pine. Finally, we measured the amount of gene flow between the pure species. We found the distribution of the pine classes is explained by environmental variables, and these distributions differ from classic distribution maps. Hybrid ancestry was biased toward lodgepole pine; however, gene flow between the two species was equal. The results of this study suggest that the hybrid zone is complex and influenced by environmental constraints. As a result of this analysis, range limits should be redefined.

  4. Kinetics and mechanism of jack bean urease inhibition by Hg2+

    Directory of Open Access Journals (Sweden)

    2012-12-01

    Full Text Available Abstract Background Jack bean urease (EC 3.5.1.5 is a metalloenzyme, which catalyzes the hydrolysis of urea to produce ammonia and carbon dioxide. The heavy metal ions are common inhibitors to control the rate of the enzymatic urea hydrolysis, which take the Hg2+ as the representative. Hg2+ affects the enzyme activity causing loss of the biological function of the enzyme, which threatens the survival of many microorganism and plants. However, inhibitory kinetics of urease by the low concentration Hg2+ has not been explored fully. In this study, the inhibitory effect of the low concentration Hg2+ on jack bean urease was investigated in order to elucidate the mechanism of Hg2+ inhibition. Results According to the kinetic parameters for the enzyme obtained from Lineweaver–Burk plot, it is shown that the Km is equal to 4.6±0.3 mM and Vm is equal to 29.8±1.7 μmol NH3/min mg. The results show that the inhibition of jack bean urease by Hg2+ at low concentration is a reversible reaction. Equilibrium constants have been determined for Hg2+ binding with the enzyme or the enzyme-substrate complexes (Ki =0.012 μM. The results show that the Hg2+ is a noncompetitive inhibitor. In addition, the kinetics of enzyme inhibition by the low concentration Hg2+ has been studied using the kinetic method of the substrate reaction. The results suggest that the enzyme first reversibly and quickly binds Hg2+ and then undergoes a slow reversible course to inactivation. Furthermore, the rate constant of the forward reactions (k+0 is much larger than the rate constant of the reverse reactions (k-0. By combining with the fact that the enzyme activity is almost completely lost at high concentration, the enzyme is completely inactivated when the Hg2+ concentration is high enough. Conclusions These results suggest that Hg2+ has great impacts on the urease activity and the established inhibition kinetics model is suitable.

    There is considerable evidence that biodiversity promotes multiple ecosystem functions (multifunctionality), thus ensuring the delivery of ecosystem services important for human well-being. However, the mechanisms underlying this relationship are poorly understood, especially in natural ecosystems. We develop a novel approach to partition biodiversity effects on multifunctionality into three mechanisms and apply this to European forest data. We show that throughout Europe, tree diversity is positively related with multifunctionality when moderate levels of functioning are required, but negatively when very high function levels are desired. For two well-known mechanisms, ‘complementarity' and ‘selection', we detect only minor effects on multifunctionality. Instead a third, so far overlooked mechanism, the ‘jack-of-all-trades' effect, caused by the averaging of individual species effects on function, drives observed patterns. Simulations demonstrate that jack-of-all-trades effects occur whenever species effects on different functions are not perfectly correlated, meaning they may contribute to diversity–multifunctionality relationships in many of the world's ecosystems.

    Full Text Available A 4-year-old female Jack Russell terrier dog exhibited vomiting and severe jaundice of the visible mucous membranes and skin. Ultrasonography revealed diffuse areas of high echogenicity and focal areas of low echogenicity in the left lobe of the liver. On macroscopic observation of the biopsied liver specimen, many scattered irregularly shaped red spots were observed on the liver surface and on the cut surface. Histopathologically, there was loss of the interlobular bile duct and cholangitis accompanied by infiltration of pigment-laden macrophages in the Glisson’s capsule. Therefore, in the present case the dog was diagnosed with destructive cholangitis.

  9. Transcriptome resources and functional characterization of monoterpene synthases for two host species of the mountain pine beetle, lodgepole pine (Pinus contorta) and jack pine (Pinus banksiana)

    Science.gov (United States)

    2013-01-01

    Background The mountain pine beetle (MPB, Dendroctonus ponderosae) epidemic has affected lodgepole pine (Pinus contorta) across an area of more than 18 million hectares of pine forests in western Canada, and is a threat to the boreal jack pine (Pinus banksiana) forest. Defence of pines against MPB and associated fungal pathogens, as well as other pests, involves oleoresin monoterpenes, which are biosynthesized by families of terpene synthases (TPSs). Volatile monoterpenes also serve as host recognition cues for MPB and as precursors for MPB pheromones. The genes responsible for terpene biosynthesis in jack pine and lodgepole pine were previously unknown. Results We report the generation and quality assessment of assembled transcriptome resources for lodgepole pine and jack pine using Sanger, Roche 454, and Illumina sequencing technologies. Assemblies revealed transcripts for approximately 20,000 - 30,000 genes from each species and assembly analyses led to the identification of candidate full-length prenyl transferase, TPS, and P450 genes of oleoresin biosynthesis. We cloned and functionally characterized, via expression of recombinant proteins in E. coli, nine different jack pine and eight different lodgepole pine mono-TPSs. The newly identified lodgepole pine and jack pine mono-TPSs include (+)-α-pinene synthases, (-)-α-pinene synthases, (-)-β-pinene synthases, (+)-3-carene synthases, and (-)-β-phellandrene synthases from each of the two species. Conclusion In the absence of genome sequences, transcriptome assemblies are important for defence gene discovery in lodgepole pine and jack pine, as demonstrated here for the terpenoid pathway genes. The product profiles of the functionally annotated mono-TPSs described here can account for the major monoterpene metabolites identified in lodgepole pine and jack pine. PMID:23679205

    A study is being conducted to evaluate the feasibility of using Jack Pines for the phytoremediation of diesel-contaminated soils in northern Saskatchewan. The sites have some level of diesel contamination from spills associated with generators belonging to SaskTel. The first phase of the study was conducted under controlled conditions in a greenhouse. Seedlings of Jack Pine were planted in sand with a range of diesel concentrations. A control planting of seedlings with no diesel was also conducted. The study also included control pots of sand with diesel and no seedlings for comparison of diesel degradation. The results from this first phase will help determine the feasibility of performing more extensive testing of phytoremediation on site in northern Saskatchewan. Results will be conclusive in August 2000. So far, the results show that Jack Pines can survive in soil highly contaminated with hydrocarbons. The second phase will include field trials. Diesel concentrations at the sites range from 0 ppm to 30,000 ppm. 4 refs., 2 tabs., 5 figs

    Full Text Available In the book “God - A Biography,” Jack Miles aims to introduce ourselves Creator-God as a literary character. Miles developed a narrative based on concept aristotelian, in other words, the structure of the work is made from beginning to end. This procedure established a harmony arising from the interaction between the parties, which contributes to scrutinize the precise details of the story of the main protagonist. We decided to highlight that time some characteristics of the main character of the work and compare them to the character Hamlet, by William Shakespeare, because from the beginning of the narrative to completion Miles calls the reader’s attention to the play Shakespeare.

    Full Text Available This paper deals with the construction of the postmodern identity of Jack Gladney, the main character in Don DeLillo’s White Noise (1985. Employing (postmodern, social psychology, and psychoanalytic theories of Zygmunt Bauman, Erich Fromm, Jean Baudrillard, and Gilles Lipovetsky, it analyzes the construction of Gladney’s character through his social roles as professor, husband, and consumer in the narrow sense of the word in order to deduce that his consumerist practices have spread to all aspects of his life. This reading reveals a new interpretation of Gladney’s fear of death; it shows that Gladney’s thanatophobia represents a consequence of his atheistic worldview. Namely, unable to find a haven in religion, he unsuccessfully seeks the meaning of life and death elsewhere, mainly in consumerism, which is identified as the source of his alienation from himself, people, and God. This paper suggests that numerous problems of postmodern life are caused by the lack of faith in God and proposes a conclusion that religion itself could be the answer to the difficulties faced by postmodern individuals with fragmented identities such as Jack Gladney.

    Manuka honey (Leptospermum scoparium) exerts a strong antibacterial effect. Bacterial enzymes are an important target for antibacterial compounds. The enzyme urease produces ammonia and enables bacteria to adapt to an acidic environment. A new enzymatic assay, based on photometric detection of ammonia with ninhydrin, was developed to study urease activity. Methylglyoxal (MGO) and its precursor dihydroxyacetone (DHA), which are naturally present in manuka honey, were identified as jack bean urease inhibitors with IC 50 values of 2.8 and 5.0mM, respectively. Urease inhibition of manuka honey correlates with its MGO and DHA content. Non-manuka honeys, which lack MGO and DHA, showed significantly less urease inhibition. MGO depletion from manuka honey with glyoxalase reduced urease inhibition. Therefore, urease inhibition by manuka honey is mainly due to MGO and DHA. The results obtained with jack bean urease as a model urease, may contribute to the understanding of bacterial inhibition by manuka honey. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available Background: To investigate the effect of Eurycoma longifolia Jack root extract on serum lipids in rats. Methods: Twenty-six mature male albino Wistar rats were used in this study. A group of 18 rats were fed a high fat and high cholesterol diet for 4 weeks, after which their lipid profile was compared to the control group, who were kept on a normal diet. The rats were then further divided into three groups, the Cf group that continued to feed on a high fat and cholesterol diet only, and group A and group B who continued on a high fat diet with the addition of 5 mg/kg and 10 mg/kg of Eurycoma longifolia Jack root extract respectively for 4 weeks. After the 4 week period, the rat's lipid profiles were analysed again. Results: Group A and B showed significant total cholesterol reduction when compared to the Cf group, 140 ± 7.23, 139.63 ± 7.95, 192.14 ± 8.96 mg/dL respectively (p < 0.001. The total cholesterol/HDL ratio in group A was 5 however there was a sharp increase in group B to a high-risk level of 9.2 indicating a significant drop in HDL levels. The LDL level increased significantly in both group A and B compared to the Cf group. Conclusions: Eurycoma longifolia Jack root extract is effective in lowering total cholesterol, however the dose needs to be adjusted to prevent an excessive decrease in HDL levels.

    User-generated smartphone applications have created a new level of virtual connectivity for gay males, one in which users can create profiles and meet other users as nearby or as far away as possible. For those within close proximity, the other users can be considered their "virtual neighbors." Although the applications are theoretically designed to be places of inclusion and not exclusion, where any gay male with economic means can download an application, many profiles have been created that exclude other users. Through an examination of profiles on one such application, Jack'd, exclusion is found in the way users celebrate and reinforce ideas of traditional masculinity and denigrate and reinforce stereotypic ideas of femininity embodied by some gay men. Jack'd, and other user-generated smartphone applications, can be read as virtual neighborhoods where one is excluded based on their gender performance.

    Full Text Available The frequency of microincrement formation in sagittae otoliths of jack mackerel Trachurus symmetricus was validated using experiments on captive fish. Adult jack mackerel were injected with a dose of 100 mg of oxytetracycline/kg of fish. A second injection was performed 30 days later. The fish were then sacrificed and their sagittae otoliths were extracted. Thin sections of the otoliths were prepared and observed through an epifluorescent microscope using ultraviolet light. Two fluorescent marks corresponding to the two injections were clearly visible. The average number of microincrements between the two fluorescent marks was 29 (n=10; S.D.=1.63 and the median was 29.3. The Wilcoxon signed-rank test indicated that this value was not significantly different from 30. This result indicates that microincrements in otoliths of adult jack mackerel of between 28.4 and 37.7 cm fork length are formed with a daily frequency.

    Historical data show that outbreaks of the tree killing mountain pine beetle are often preceded by periods of drought. Global climate change impacts drought frequency and severity and is implicated in the range expansion of the mountain pine beetle into formerly unsuitable habitats. Its expanded range has recently reached the lodgepole × jack pine hybrid zone in central Alberta, Canada, which could act as a transition from its historical lodgepole pine host to a jack pine host present in the boreal forest. This field study tested the effects of water limitation on chemical defenses of mature trees against mountain pine beetle-associated microorganisms and on beetle brood success in lodgepole × jack pine hybrid trees. Tree chemical defenses as measured by monoterpene emission from tree boles and monoterpene concentration in needles were greater in trees that experienced water deficit compared to well-watered trees. Myrcene was identified as specific defensive compound, since it significantly increased upon inoculation with dead mountain pine beetles. Beetles reared in bolts from trees that experienced water deficit emerged with a higher fat content, demonstrating for the first time experimentally that drought conditions benefit mountain pine beetles. Further, our study demonstrated that volatile chemical emission from tree boles and phloem chemistry place the hybrid tree chemotype in-between lodgepole pine and jack pine, which might facilitate the host shift from lodgepole pine to jack pine.

  3. Secondary vegetation succession on jack pine (Pinus banksiana) cutovers in northeastern Ontario, Canada

    The effects of different harvesting and site preparation methods on competing vegetation were studied in nine jack pine (Pinus banksiana) cutovers in northeastern Ontario, Canada. Six different treatments plus glyphosate herbiciding and no herbiciding were applied: 1) tree-length harvesting followed by trenching, and full-tree harvesting followed by five site preparations, 2) no site preparation, 3) trenching and 4) blading and compaction as well as blading followed by two planting densities, 5) 1.2m and 6) 2m. Competing vegetation was assessed preharvest and years 1, 2, 3, and 5 postharvest. Data was also available from nine juvenile sites as well as nine semimature sites. Data collection consisted of coverage values of each species as well as structural data for main life forms in height classes. Growth and health data of the planted jack pine seedlings were also available. The data was analyzed using detrended correspondence analysis (DCA), diversity indices and tabular analysis. Three years after the herbicide application there is no difference between the total coverage in the halfplots that have received herbiciding and those that have not, but an alteration of the relative abundance of species groups has developed; glyphosate herbiciding promotes grasses over shrubs. When no site preparation is applied, shrubs increase and compete with the seedlings, whose growth is cut in half compared to the ones that have been site prepared by trenching. Five years after blading, and blading plus compaction, there is still very little vegetation in the research plots, but there is no reduction of the survival rate and growth of the jack pine seedlings. More dense planting after this treatment leads to more competing vegetation, probably due to increased availability of moisture. Grasses do not seem to be affected by compaction and pioneer mosses are promoted by this treatment but compaction leads to a significant reduction of the total coverage of competing vegetation

  5. Fatty Acid Composition of Novel Host Jack Pine Do Not Prevent Host Acceptance and Colonization by the Invasive Mountain Pine Beetle and Its Symbiotic Fungus

    Fatty acids are major components of plant lipids and can affect growth and development of insect herbivores. Despite a large literature examining the roles of fatty acids in conifers, relatively few studies have tested the effects of fatty acids on insect herbivores and their microbial symbionts. Particularly, whether fatty acids can affect the suitability of conifers for insect herbivores has never been studied before. Thus, we evaluated if composition of fatty acids impede or facilitate colonization of jack pine (Pinus banksiana) by the invasive mountain pine beetle (Dendroctonus ponderosae) and its symbiotic fungus (Grosmannia clavigera). This is the first study to examine the effects of tree fatty acids on any bark beetle species and its symbiotic fungus. In a novel bioassay, we found that plant tissues (hosts and non-host) amended with synthetic fatty acids at concentrations representative of jack pine were compatible with beetle larvae. Likewise, G. clavigera grew in media amended with lipid fractions or synthetic fatty acids at concentrations present in jack pine. In contrast, fatty acids and lipid composition of a non-host were not suitable for the beetle larvae or the fungus. Apparently, concentrations of individual, rather than total, fatty acids determined the suitability of jack pine. Furthermore, sampling of host and non-host tree species across Canada demonstrated that the composition of jack pine fatty acids was similar to the different populations of beetle’s historical hosts. These results demonstrate that fatty acids composition compatible with insect herbivores and their microbial symbionts can be important factor defining host suitability to invasive insects.

    Full Text Available This paper analyses information on various macro environmental variables available since 1876 for the Southeast Pacific and more recent data on Jack mackerel Trachurus murphyi (Nichols, 1920 landings and biomass in the Peruvian sea, relating them to probable areas of water masses equivalent to Cold Coastal Waters (CCW and Subtropical Surface Waters (SSW. It is concluded that the index of the Pacific Decadal Oscillation (PDO presents expressions of variability that are consistent with those found for the Southern Oscillation Index (SOI and that the detected changes in biomass of Jack mackerel T. murphyiin the Peruvian sea reflect changes in the availability of the fish stock associated with secular (SOI and decadal (PDO variability patterns. These fluctuations in stock availability impact fisheries in Ecuador, Peru and northern Chile, which show significant variations in their landings and would have given a biased picture of the state of abundance, leading to wrong diagnoses of the real situation of the exploited stocks. These patterns of variability would also affect the appearance of El Niño, making them start in the southern hemisphere autumn or spring depending on whether the current PDO is positive or negative. Periods of high (1876 – 1925 and 1976 – 2012 and low (1926 – 1975 variability are also identified in relation to the Euclidean distance of the variances of the SOI; and in relation to the PDO a distinction is made between warm (1925 – 1944 and 1975 – 1994, cold (1945 – 1974 and tempered or interface periods (1895 – 1924 and 1995 – 2012, the latter being explained by the interaction between periods of high variability.

    It currently is unknown when Earth's dynamo magnetic field originated. Paleomagnetic studies indicate that a field with an intensity similar to that of the present day existed 3.5 billion years ago (Ga). Detrital zircon crystals found in the Jack Hills of Western Australia are some of the very few samples known to substantially predate this time. With crystallization ages ranging from 3.0-4.38 Ga, these zircons might preserve a record of the missing first billion years of Earth's magnetic field history. However, a key unknown is the age and origin of magnetization in the Jack Hills zircons. The identification of >3.9 Ga (i.e., Hadean) field records requires first establishing that the zircons have avoided remagnetization since being deposited in quartz-rich conglomerates at 2.65-3.05 Ga. To address this issue, we have conducted paleomagnetic conglomerate, baked contact, and fold tests in combination with U-Pb geochronology to establish the timing of the metamorphic and alteration events and the peak temperatures experienced by the zircon host rocks. These tests include the first conglomerate test directly on the Hadean-zircon bearing conglomerate at Erawandoo Hill. Although we observed little evidence for remagnetization by recent lightning strikes, we found that the Hadean zircon-bearing rocks and surrounding region have been pervasively remagnetized, with the final major overprinting likely due to thermal and/or aqueous effects from the emplacement of the Warakurna large igneous province at ∼1070 million years ago (Ma). Although localized regions of the Jack Hills might have escaped complete remagnetization, there currently is no robust evidence for pre-depositional (>3.0 Ga) magnetization in the Jack Hills detrital zircons.

  11. Effects of introgression on the genetic population structure of two ecologically and economically important conifer species: lodgepole pine (Pinus contorta var. latifolia) and jack pine (Pinus banksiana).

    Forest trees exhibit a remarkable range of adaptations to their environment, but as a result of frequent and long-distance gene flow, populations are often only weakly differentiated. Lodgepole and jack pine hybridize in western Canada, which adds the opportunity for introgression through hybridization to contribute to population structure and (or) adaptive variation. Access to large sample size, high density SNP datasets for these species would improve our ability to resolve population structure, parameterize introgression, and separate the influence of demography from adaptation. To accomplish this, 454 transcriptome reads for lodgepole and jack pine were assembled using Newbler and MIRA, the assemblies mined for SNPs, and 1536 SNPs were selected for typing on lodgepole pine, jack pine, and their hybrids (N = 536). We identified population structure using both Bayesian clustering and discriminate analysis of principle components. Introgressed SNP loci were identified and their influence on observed population structure was assessed. We found that introgressed loci resulted in increased differentiation both within lodgepole and jack pine populations. These findings are timely given the recent mountain pine beetle population expansion in the hybrid zone, and will facilitate future studies of adaptive traits in these ecologically important species.

    Simple Summary The identity of Jack the Ripper remains one of the greatest unsolved crime mysteries in history. Jack was notorious both for the brutality of his murders and also for his habit of stealing organs from his victims. His speed and skill in doing so, in conditions of poor light and haste, fueled theories he was a surgeon. However, re-examination of a mortuary sketch from one of his victims has revealed several key aspects that strongly suggest he had no professional surgical training. Instead, the technique used was more consistent with that of a slaughterhouse worker. There were many small-scale slaughterhouses in East London in the 1880s, within which conditions were harsh for animals and workers alike. The brutalizing effects of such work only add to concerns highlighted by modern research that those who commit violence on animals are more likely to target people. Modern slaughterhouses are more humane in some ways but more desensitizing in others, and sociological research has indicated that communities with slaughterhouses are more likely to experience the most violent of crimes. The implications for modern animal slaughtering, and our social reliance on slaughterhouses, are explored. Abstract Hundreds of theories exist concerning the identity of “Jack the Ripper”. His propensity for anatomical dissection with a knife—and in particular the rapid location and removal of specific organs—led some to speculate that he must have been surgically trained. However, re-examination of a mortuary sketch of one of his victims has revealed several aspects of incisional technique highly inconsistent with professional surgical training. Related discrepancies are also apparent in the language used within the only letter from Jack considered to be probably authentic. The techniques he used to dispatch his victims and retrieve their organs were, however, highly consistent with techniques used within the slaughterhouses of the day. East London in the 1880s had

    A five-year experimental study was conducted to evaluate the response of an upland jack-pine (Pinus banksiana) forest to elevated levels of nitrogen (N) deposition in Northern Alberta. N deposition in the region is expected to increase with industrial expansion of oil sands activity, and there is regional interest to set N critical loads for sensitive ecosystems. In this study, N was applied as NH4NO3 above a jack-pine canopy via helicopter, annually for five years (2010-2015) at dosages equivalent to 5, 10, 15, 20 and 25 kg N ha-1 yr-1. Approximately 35% of the applied N was retained in the canopy while 65% reached understory vegetation dominated by lichens and mosses. We measured a significant increase in tissue N concentrations of common ground lichens (Cladonia mitis and C. stellaris) and ground moss (Pleurozium schreberi) as well as epiphytic lichens (Hypogymnia physodes and Evernia mesomorpha). On an annual basis, the applied N was primarily captured in the lichen and moss understory, dominated by C. mitis. In the highest treatments, N concentrations in C. mitis were 1.5-2.5 times greater than pre-treatment values. Peak N concentrations in the ground moss Pleurozium schreberi (1.4%) indicate that a threshold of N saturation was reached by year 3. We observed no changes in community composition of vascular and non-vascular plants, or changes in vascular plant tissue N. Chlorophyll levels in C. mitis increased with N treatment, but there was no indication of toxicity or changes to decomposition and growth. After five years of N application, only Peltigera polydactylon, a ground cyanolichen, appeared to be negatively impacted where the thalli showed necrosis at deposition loads >10kg N ha-1 yr-1. No changes to biomass or N ecosystem processes were observed. Based on these observations, we provide evidence that the first adverse ecological effects of N deposition in jack-pine stands occurred at deposition rates of 10 kg N ha-1 yr-1.

    Full Text Available In central Canada, long fire history reconstructions are rare. In a context where both anthropogenic and climate influences on fire regime have changed, Parks Canada has a mandate to maintain ecological integrity. Here we present a fire history derived from fire-scarred jack pine (Pinus banksiana Lamb. trees growing at their southern distribution limit in Riding Mountain National Park (RMNP. In Lake Katherine Fire Management Unit (LKFMU, a subregion within the park, fire history was reconstructed from archival records, tree-ring records, and charcoal in lake sediment. From about 1450 to 1850 common era (CE the fire return intervals varied from 37 to 125 years, according to models. During the period 1864–1930 the study area burned frequently (Weibull Mean Fire Intervals between 2.66 and 5.62 years; this period coincided with the end of First Nations occupation and the start of European settlement. Major recruitment pulses were associated with the stand-replacing 1864 and 1894 fires. This period nevertheless corresponded to a reduction in charcoal accumulation. The current fire-free period in LKFMU (1930–today coincides with RMNP establishment, exclusion of First Nations land use and increased fire suppression. Charcoal accumulation further decreased during this period. In the absence of fire, jack pine exclusion in LKFMU is foreseeable and the use of prescribed burning is advocated to conserve this protected jack pine ecosystem, at the southern margins of its range, and in the face of potential climate change.

    Baicalin (BA) is the principal component of Radix Scutellariae responsible for its pharmacological activity. In this study, kinetics and mechanism of inhibition by BA against jack-bean urease were investigated for its therapeutic potential. It was revealed that the IC50 of BA against jack-bean urease was 2.74 ± 0.51 mM, which was proved to be a competitive and concentration-dependent inhibition with slow-binding progress curves. The rapid formation of initial BA-urease complex with an inhibition constant of K i = 3.89 × 10−3 mM was followed by a slow isomerization into the final complex with an overall inhibition constant of K i* = 1.47 × 10−4 mM. High effectiveness of thiol protectors against BA inhibition indicated that the strategic role of the active-site sulfhydryl group of the urease was involved in the blocking process. Moreover, the inhibition of BA was proved to be reversible due to the fact that urease could be reactivated by dithiothreitol but not reactant dilution. Molecular docking assay suggested that BA made contacts with the important activating sulfhydryl group Cys-592 residues and restricted the mobility of the active-site flap. Taken together, it could be deduced that BA was a competitive inhibitor targeting thiol groups of urease in a slow-binding manner both reversibly and concentration-dependently, serving as a promising urease inhibitor for treatments on urease-related diseases.

    Full Text Available A new critical edition of a collection of nearly one hundred Latin prayers connected with Gertrude of Poland (ca 1025-1108, Polish princess, wife of Izaslav of Kiev, has revived an interest in this exceptional example of literature and religiousness o f the eleventh century. The multiplicity of issues connected with the prayer book requires further consideration. An example might be the iconographic concord of prayers both with the accompanying miniatures and the works of art, which Gertrude encountered in the west as well as in the east -from Rhineland, where she was educated to Ruthenia, where she stayed longest. The paper examines the issue in relation to the Marian subject matter. A problem that has not as yet been touched upon is the history o f the prayers in the centuries that followed, as a singular example from the 15th century regarding one such prayer reveals. The prayers are mostly theocentric and Christocentric in character, but in many of them the intercessive role of St. Mary is evoked. In Ruthenia Gertrude was exposed to representations of the Deesis type, characteristic of eastern Christianity. From the prince’s box in St. Sophia’s Cathedral in Kiev she saw them in a form of three tondi, situated on the arch encasing the central apse, while in the apse itself was a monumental depiction of St. Mary-Oranta, eternal and omnipotent advocate in heaven, referred to in prayers as “oratrix celorum”. Of the four prayers directed exclusively to Mary two are laudatory and supplicatory and the other two just laudatory. The latter are characterized by a sophisticated literary form, division into phrases, employment of internal and external rhymes and a number of rhetorical figures (alliteration, oxymorons. A solar epithet appears here among others (“sola pulcherrima super solem”. A lot of Marian epithets, such as the Mother of God, Our Lady and the Queen of the whole world (“Dei genitrix”, “domina et regina totius orbis

    Coniferous trees have both constitutive and inducible defences that deter or kill herbivores and pathogens. We investigated constitutive and induced monoterpene responses of jack pine (Pinus banksiana Lamb.) to a number of damage types: a fungal associate of the mountain pine beetle (Dendroctonus ponderosae Hopkins), Grosmannia clavigera (Robinson-Jeffrey & R.W. Davidson); two phytohormones, methyl jasmonate (MJ) and methyl salicylate (MS); simulated herbivory; and mechanical wounding. We only included the fungal, MJ and mechanical wounding treatments in the field experiments while all treatments were part of the greenhouse studies. We focused on both constitutive and induced responses between juvenile and mature jack pine trees and differences in defences between phloem and needles. We found that phytohormone applications and fungal inoculation resulted in the greatest increase in monoterpenes in both juvenile and mature trees. Additionally, damage types differentially affected the proportions of individual monoterpenes: MJ-treated mature trees had higher myrcene and β-pinene than fungal-inoculated mature trees, while needles of juveniles inoculated with the fungus contained higher limonene than MJ- or MS-treated juveniles. Although the constitutive monoterpenes were higher in the phloem of juveniles than mature jack pine trees, the phloem of mature trees had a much higher magnitude of induction. Further, induced monoterpene concentrations in juveniles were higher in phloem than in needles. There was no difference in monoterpene concentration between phytohormone applications and G. clavigera inoculation in mature trees, while in juvenile trees MJ was different from both G. clavigera and simulated herbivory in needle monoterpenes, but there was no difference between phytohormone applications and simulated herbivory in the phloem.

    In a variety of taxa, males deploy alternative reproductive tactics to secure fertilizations. In many species, small "sneaker" males attempt to steal fertilizations while avoiding encounters with larger, more aggressive, dominant males. Sneaker males usually face a number of disadvantages, including reduced access to females and the higher likelihood that upon ejaculation, their sperm face competition from other males. Nevertheless, sneaker males represent an evolutionarily stable strategy under a wide range of conditions. Game theory suggests that sneaker males compensate for these disadvantages by investing disproportionately in spermatogenesis, by producing more sperm per unit body mass (the "fair raffle") and/or by producing higher quality sperm (the "loaded raffle"). Here, we test these models by competing sperm from sneaker "jack" males against sperm from dominant "hooknose" males in Chinook salmon. Using two complementary approaches, we reject the fair raffle in favor of the loaded raffle and estimate that jack males were ∼1.35 times as likely as hooknose males to fertilize eggs under controlled competitive conditions. Interestingly, the direction and magnitude of this skew in paternity shifted according to individual female egg donors, suggesting cryptic female choice could moderate the outcomes of sperm competition in this externally fertilizing species.

  3. Detrital Zircons From the Jack Hills and Mount Narryer, Western Australia: Geochronological, Morphological, and Geochemical Evidence for Diverse >4000 Ma Source Rocks

    Detrital zircons from all major clastic units in the Jack Hills and Mount Narryer metasedimentary belts, Western Australia, were analyzed for morphology, internal zoning, inclusion mineralogy, age, and trace element concentrations (latter two obtained by laser-ablation microprobe ICPMS). The results show that zircons were derived from a wide diversity of rocks, including previously described, >4000 Ma grains that are older than any known terrestrial rocks. In three metaconglomerate samples from the western Jack Hills, 4200-3800 Ma zircons ("old grains") comprise 14% of the population, 3800-3600 Ma grains form only 2%, and 3550-3250 Ma zircons ("young grains") are dominant with a significant peak at 3380 Ma. Old and young grains are interpreted as being from similar rock types because they are indistinguishable in trace element concentrations, size (several hundred microns), morphology (subequant, typically fragmented), internal zoning (typically both oscillatory and sector), and U concentration (50-200 ppm). Many of these properties suggest an intermediate plutonic source, whereas an evolved granitic source was previously interpreted from rare-earth element and oxygen isotope data. Detrital zircons in quartzites and metaconglomerates at Mount Narryer differ significantly from zircons from the western Jack Hills. Old grains comprise only 3% (most of which are 4200-4100 Ma), 3800-3600 Ma zircons form 31%, and there are peaks at 3650, 3600, and 3500 Ma. Old and young grains have similar properties that suggest granitic sources, such as elongate prismatic morphology, oscillatory zoning, high U concentrations (100-600 ppm), and xenotime and monazite inclusions. Trace element concentrations are broadly similar to those in Jack Hills zircons, with notable exceptions being generally higher U, smaller Ce and Eu anomalies, and lower Nb/Ta. It is considered unlikely that Jack Hills zircons were derived from granitic gneisses that surround the metasedimentary belts because

    The plant design management system (PDMS) is an integrated application which includes a database and is useful when designing complex 3-D industrial projects. It could be used to simplify the most difficult part of a subsea oil extraction project—detailed pipeline design. It could also be used to integrate the design of equipment, structures, HVAC, E-ways as well as the detailed designs of other specialists. This article mainly examines the applicability of the Vantage PDMS database to pipeline projects involving jack-up drilling ships. It discusses the catalogue (CATA) of the pipeline, the spec-world (SPWL) of the pipeline, the bolt tables (BLTA) and so on. This article explains the main methods for CATA construction as well as problem in the process of construction. In this article, the authors point out matters needing attention when using the Vantage PDMS database in the design process and discuss partial solutions to these questions.

    1975-08-11

    Robishaw Engineering Inc., Houston, has designed and built a jack-up platform based on a modular flotation and erection system that allows exploratory and development drilling year round in any location that cannot be reached by conventional equipment. All components are light enough to be transported by helicopters rated for 4000-lb loads, yet strong and buoyant enough to serve as working platforms. The pile-supported self-elevating drilling platform consists of H-shaped steel girders joined by pin connectors and tension wires. Deck panels are steel-plated. When elevated on steel pilings, the platform can support loads imposed by rigs capable of drilling to 18,000 ft. One such unit is currently being used in the Peruvian rain forest.

  8. Characterization of inclusions in terrestrial impact formed zircon: Constraining the formation conditions of Hadean zircon from Jack Hills, Western Australia

    2017-12-01

    Due to the discovery and subsequent geochemical analysis of Hadean terrestrial material (e.g. detrital zircon from Jack Hills, Western Australia), a dramatic paradigm shift has occurred in the hypothesized near surface conditions of the first 500 million years of Earth's evolution. From a hellish setting riddled with impactors and not fit for life to a much milder environment that may have been uniquely suitable for the origin of life. Geochemical analyses of these ancient materials have been used to suggest the presence of water at or near the surface as well as the existence of continental crust during the Hadean, both of which have been suggested as necessary for the origin of life. However, the intensity of extraterrestrial bombardment during the Hadean and the effects of such events on the origin of life remains poorly understood. Clearly, as evidenced by Phanerozoic impact events, extraterrestrial impactors have the potential to dramatically effect the environment, particularly the biosphere. Early Earth likely experienced multiple large impact events, as evidenced by the lunar record, however whether those impacts were sufficient to frustrate the origin of life remains an open question. Although multiple lines of evidence, including the inclusion population, suggest the formation of Hadean zircon from Jack Hills as crystallizing in an under-thrust environment from S-type magmas, a recent study has suggested their formation in an impact melt environment analogous to a portion of the Sudbury Igneous Complex at the Sudbury impact structure. To determine between these two formation scenarios we have under-taken an inclusion study of terrestrial impact formed zircon from four of the largest terrestrial impact structures (Sudbury, Canada; Manicouagan, Canada; Vredefort, South Africa; Morokweng, South Africa), to compare to the vast inclusion dataset that exists for Jack Hills zircon. Preliminary data suggests a different inclusion population, from Hadean zircon

    Full Text Available The vegetation of the Jack Scott Nature Reserve in the Central Bankenveld Veld Type is classified chiefly by the Braun-Blanquet Table Method. Habitat features, physiognomy, total floristic composition, differentiating species, woody plants and prominent grasses and forbs are presented for each community. Characterizing habitat features, in order of importance for the communities, are: exposure, soil texture, geology, slope, aspect, degree of rockiness and previous ploughing. The classification correlates well with the major physiographic and climatic variation in the Reserve and generally does not cut across main physiognomic types. The communities are potentially homogeneous management units.

    Jack pine budworm ( Choristoneura pinus pinus (Free.)) is a native insect defoliator of mainly jack pine ( Pinus banksiana Lamb.) in North America east of the Rocky Mountains. Periodic outbreaks of this insect, which generally last two to three years, can cause growth loss and mortality and have an important impact ecologically and economically in terms of timber production and harvest. The jack pine budworm prefers to feed on current year needles. Their characteristic feeding habits cause discolouration or reddening of the canopy. This red colouration is used to map the distribution and intensity of defoliation that has taken place that year (current defoliation). An accurate and consistent map of the distribution and intensity of budworm defoliation (as represented by the red discolouration) at the stand and within stand level is desirable. Automated classification of multispectral imagery, such as is available from airborne and new high resolution satellite systems, was explored as a viable tool for objectively classifying current discolouration. Airborne multispectral imagery was acquired at a 2.5 m resolution with the Multispectral Electro-optical Imaging Sensor (MEIS). It recorded imagery in six nadir looking spectral bands specifically designed to detect discolouration caused by budworm and a near-infrared band viewing forward at 35° was also used. A 2200 nm middle infrared image was acquired with a Daedalus scanner. Training and test areas of different levels of discolouration were created based on field observations and a maximum likelihood supervized classification was used to estimate four classes of discolouration (nil-trace, light, moderate and severe). Good discrimination was achieved with an overall accuracy of 84% for the four discolouration levels. The moderate discolouration class was the poorest at 73%, because of confusion with both the severe and light classes. Accuracy on a stand basis was also good, and regional and within stand

    Studies of metasedimentary rocks from the Jack Hills, which host Earth's oldest known detrital minerals, have focused on zircon and occasionally monazite or xenotime, but no attention has been directed toward one of the most common mineral markers of metamorphism: garnet. Garnet can provide a record of the post-depositional, prograde metamorphic history of Archean metasedimentary rocks. Additionally, the use of a newly developed detrital garnet dating technique [1,2] may reveal information about pre-depositional metamorphism that could address lingering questions about the nature and timing of Earth's earliest tectonometamorphic events. Here we investigate garnet from the Jack Hills metasedimentary rocks to test whether they record in situ metamorphism or are a detrital relict of even older metamorphic events. We identified garnet in two bulk quartz-pebble conglomerate samples collected from the 'discovery' outcrop at Eranondoo Hill in the Jack Hills of Western Australia. Electron microprobe analyses of polished grains and SEM measurements of unpolished grain surfaces are consistent, revealing garnet composition indicative of a single generation/population of predominantly almandine-spessartine solid solution (~10-35% mole fraction spessartine). Compositional maps of garnet grains reveal little zoning and no discontinuities, most consistent with a single growth event. Dating Jack Hills' garnet via the Sm-Nd system is possible due to continued development of small sample analysis techniques, including running NdO+ TIMS analyses with Ta2O5 activator [3] permitting Ma for two point isochrons between clean garnet (Sm/Nd ≥ 1.0) and their leached inclusion populations [2]. Four grouped garnet grain separates from one sample yield preliminary dates of 2703.6×6.0Ma, 2612.4×6.0Ma, 2605.0×5.5Ma, and 2567.3×8.3Ma, while the second sample yielded a date of 2579.6×4.6 Ma (2σ). Compositional and geochronologic data indicate likely in situ garnet growth during a late

    The jack jumper ant (Myrmecia pilosula) is responsible for greater than 90% of Australian ant venom allergy. However, deaths have only been recorded in the island of Tasmania. We sought to determine the prevalence, clinical features, natural history, and predictors of severity of M pilosula sting allergy in Tasmania. We performed a random telephone survey supported by serum venom-specific IgE analysis, review of emergency department presentations, and follow-up of allergic volunteers. M pilosula, honeybee (Apis mellifera), and yellow jacket wasp (Vespula germanica) sting allergy prevalences were 2.7%, 1.4%, and 0.6% compared with annual sting exposure rates of 12%, 7%, and 2%, respectively. Similarly, emergency department presentations with anaphylaxis to M pilosula were double those for honeybee. M pilosula allergy prevalence increased with age of 35 years or greater (odds ratio [OR], 2.4) and bee sting allergy (OR, 16.9). Patients 35 years of age or older had a greater risk of hypotensive reactions (OR, 2.9). Mueller reaction grades correlated well with adrenaline use. During follow-up, 79 (70%) of 113 jack jumper stings caused anaphylaxis. Prior worst reaction severity predicted the likelihood and severity of follow-up reactions; only 3 subjects had more severe reactions. Venom-specific IgE levels and other clinical features, including comorbidities, were not predictive of severity. Sting allergy prevalence is determined by age and exposure rate. M pilosula sting exposure in Tasmania is excessive compared with that found in mainland Australia, and there is a high systemic reaction risk in allergic people on re-sting. Prior worst reaction severity (Mueller grade) and age predict reaction severity and might be used to guide management.

    Cable-in-conduit conductors (CICCs) for ITER magnets are subjected to fast changing magnetic fields during the plasma-operating scenario. In order to anticipate the limitations of conductors under the foreseen operating conditions, it is essential to have a better understanding of the stability margin of magnets. In the last decade ITER has launched a campaign for characterization of several types of NbTi and Nb3Sn CICCs comprising quench tests with a singular sine wave fast magnetic field pulse and relatively small amplitude. The stability tests, performed in the SULTAN facility, were reproduced and analyzed using two codes: JackPot-AC/DC, an electromagnetic-thermal numerical model for CICCs, developed at the University of Twente (van Lanen and Nijhuis 2010 Cryogenics 50 139-148) and multi-constant-model (MCM) (Turck and Zani 2010 Cryogenics 50 443-9), an analytical model for CICCs coupling losses. The outputs of both codes were combined with thermal, hydraulic and electric analysis of superconducting cables to predict the minimum quench energy (MQE) (Bottura et al 2000 Cryogenics 40 617-26). The experimental AC loss results were used to calibrate the JackPot and MCM models and to reproduce the energy deposited in the cable during an MQE test. The agreement between experiments and models confirm a good comprehension of the various CICCs thermal and electromagnetic phenomena. The differences between the analytical MCM and numerical JackPot approaches are discussed. The results provide a good basis for further investigation of CICC stability under plasma scenario conditions using magnetic field pulses with lower ramp rate and higher amplitude.

    Motivation: Pathogens infect their host and hijack the host machinery to produce more progeny pathogens. Obligate intracellular pathogens, in particular, require resources of the host to replicate. Therefore, infections by these pathogens lead to alterations in the metabolism of the host, shifting in favor of pathogen protein production. Some computational identification of mechanisms of host-pathogen interactions have been proposed, but it seems the problem has yet to be approached from the metabolite-hijacking angle. Results: We propose a novel computational framework, Hi-Jack, for inferring pathway-based interactions between a host and a pathogen that relies on the idea of metabolite hijacking. Hi-Jack searches metabolic network data from hosts and pathogens, and identifies candidate reactions where hijacking occurs. A novel scoring function ranks candidate hijacked reactions and identifies pathways in the host that interact with pathways in the pathogen, as well as the associated frequent hijacked metabolites. We also describe host-pathogen interaction principles that can be used in the future for subsequent studies. Our case study on Mycobacterium tuberculosis (Mtb) revealed pathways in human-e.g. carbohydrate metabolism, lipids metabolism and pathways related to amino acids metabolism-that are likely to be hijacked by the pathogen. In addition, we report interesting potential pathway interconnections between human and Mtb such as linkage of human fatty acid biosynthesis with Mtb biosynthesis of unsaturated fatty acids, or linkage of human pentose phosphate pathway with lipopolysaccharide biosynthesis in Mtb. © The Author 2015.

  1. Proterozoic events recorded in quartzite cobbles at Jack Hills, Western Australia: New constraints on sedimentation and source of > 4 Ga zircons

    2010-03-01

    Rare heavy mineral bands within quartzite cobbles were identified in two conglomerate units within the Jack Hills belt, Western Australia. Seven zircon-bearing cobbles were analysed from one location (site 152) and three from another (site 154), both approximately 1 km west of the site where zircons in excess of 4 Ga are abundant (W74 'discovery' site). Individual pebbles from the 152 site reveal three distinctive features, containing either zircons > 3.0 Ga in age, 4 Ga was discovered from the entire suite of pebbles, in contrast to the well-studied W74 site. A single detrital zircon with an age of 1220 ± 42 Ma from location 152 is the youngest grain so far reported from sedimentary rocks at Jack Hills. It shows magmatic oscillatory zoning and thus implies at least two sedimentary cycles within the Proterozoic; requiring erosion of an igneous precursor, incorporation into a clastic sediment, induration and subsequent erosion and transport to be hosted in the conglomerate. The nearest source for rocks of this age is the Bangemall Supergroup in the Collier Basin, ˜ 100 km northeast in the Capricorn Orogen. This would imply tectonic interleaving of originally more extensive Bangemall rocks, possibly related to activity along the Cargarah Shear Zone that traverses the Jack Hills belt. The lack of > 4.1 Ga zircons in the pebbles is highly significant, suggesting the immediate source of ancient zircons was no longer present at the Earth's surface. This equates with a general lack of ancient crystals noted in rocks that contain Proterozoic zircons from previous studies and implies that such grains diminish in number as earlier sedimentary rocks were successively recycled.

    Tight hamstrings are reported to be one of the causes of low back pain. However, there have been few reports on effective stretching procedures for the tight hamstrings. The so-called jack-knife stretch, an active-static type of stretching, can efficiently increase the flexibility of tight hamstrings. To evaluate hamstring tightness before and after the 4-week stretching protocol in healthy volunteer adults and patients aged under 18 years with low back pain. For understanding the hamstrings tightness, we measured two parameters including (1) finger to floor distance (FFD) and (2) pelvis forward inclination angle (PFIA). Eight healthy adult volunteers who had no lumbar or hip problems participated in this study (mean age: 26.8 years). All lacked flexibility and their FFD were positive before the experiment. Subjects performed 2 sets of the jack-knife stretch every day for 4 weeks. One set consisted of 5 repetitions, each held for 5 s. Before and during the 4-week experiment, the FFD and PFIA of toe-touching tests were measured weekly. For 17 of the sports players aged under 18, only FFD was measured. In adult volunteers, FFD was 14.1 ± 6.1 cm before the experiment and decreased to -8.1 ± 3.7 cm by the end of week 4, indicating a gain in flexibility of 22.2 cm. PFIA was 50.6 ± 8.2 before the experiment and 83.8 ± 5.8 degrees after. Before and after the experiment, the differences were significant (p hamstrings.

    In the late spring or early summer of 2012, a flood emanated from a small moraine-dammed lake on the northeast flank of Three Fingered Jack in the Mount Jefferson Wilderness. Channel erosion or slope collapse breached the natural dam of the lake, leading to a sudden lowering of lake level by 2.8 m and discharge of 12,700 cubic meters (m3) of water. The resulting debris flow formed a bouldery deposit extending about 0.35 km downslope.

  4. What can zircon ages from the Jack Hills detrital zircon suite really tell us about Hadean geodynamics?

    Science.gov (United States)

    Whitehouse, Martin; Nemchin, Alexander

    2015-04-01

    As the only direct sample of the Hadean Earth, detrital zircon grains from the Jack Hills, Western Australia, have been the subject of intense investigation over the almost three decades since their discovery. A wide variety of geochemical and isotopic analyses of these grains, as well as their mineral inclusions, have been used variously to support two fundamentally different models for Hadean geodynamics: (i) Some form of (not necessarily modern-style) plate recycling generating felsic (continental-type?) crust at the boundaries [1, 2], or conversely (ii) the persistence of a long-lived, stagnant basaltic lid within which magmatism occurred as a result of internal temperature perturbations and/or impacts [3, 4], a model also generally consistent with a wide range of observations from post-Hadean geochemical reservoirs. Despite the considerable time and resources expended, the majority of these studies uncritically accept the individual U-Pb zircon ages, even though their veracity is key to many of the interpretations [5, 6]. We report here the results of an in-depth evaluation of all published (and new) U-Pb ages from the Jack Hills zircon suite in order to define age populations that can be used with a high degree of confidence in geodynamic interpretations. A notable problem in the interpretation of U-Pb data from ancient zircon grains (including those as young as the Neoarchean) is that disturbance of the systematics even several 100 Ma after crystallization causes data to spread along the concordia curve without becoming discernably discordant within the relatively large error bounds associated with U/Pb ages from in situ dating methods (e.g. SIMS). While 207Pb/206Pb ages are typically more precise, individually they provide no means to detect Pb-loss-induced younging. However, if two or preferably more analyses have been made in the same zircon growth zone, a reasonable evaluation of the possibility of Pb-loss can be made. In the available Jack Hills zircon

    With the syndrome of malignant narcissism, which is characterised by narcissistic personality disorder, anti-social behaviour, sadism and a marked tendency to paranoid reactions, Kernberg (1985, 1996) describes an independent form of pathological narcissism. According to Stone (1996) this is found in many mass-murderers and serial killers. On the basis of the example of Jack Unterweger the connection between malignant narcissism and sexual offence is discussed as to psychodynamic development, personality structure and psychopathology. Unterweger, who was convicted to lifelong imprisonment in 1976 for sadistic sexual murder, became a wellknown writer in prison and was released prematurely in 1990 as the Austria case of successful rehabilitation. As stated in the sentence passed against him he killed 11 prostitutes in Europe and the USA within the next 18 months, but never pleaded guilty. Psychiatric examination revealed numerous elements of malignant narcissism and the constellation of his development and life was typical of serial offenders.

    2010-10-01

    Eurycoma longifolia Jack is an herbal medicinal plant of South-East Asian origin, popularly recognized as 'Tongkat Ali.' The plant parts have been traditionally used for its antimalarial, aphrodisiac, anti-diabetic, antimicrobial and anti-pyretic activities, which have also been proved scientifically. The plant parts are rich in various bioactive compounds (like eurycomaoside, eurycolactone, eurycomalactone, eurycomanone, and pasakbumin-B) among which the alkaloids and quassinoids form a major portion. Even though toxicity and safety evaluation studies have been pursued, still a major gap exists in providing scientific base for commercial utilization and clearance of the Tongkat Ali products with regard to consumer's safety. The present review aims at reviewing the research works undertaken till date, on this plant in order to provide sufficient baseline information for future works and for commercial exploitation.

  10. Safe jack-up method permits repairs of tank bottoms and foundations

    1991-01-01

    The oil and chemical industries use many thousands of steel tanks to store crude oil, oil products, and chemical liquids. The majority of these tanks are 30-40 years old. Tank bottoms are likely to begin leaking in the coming years, as these tanks get older. The European technique of jacking up a tank and repairing its foundation allows the thorough inspection of the underside of the tank bottom and the removal of saturated foundation material. And the possibility of soil and groundwater pollution is reduced to a minimum. With good, regular maintenance, the lifetime of a storage tank is very long. But experience has shown that special attention should be paid to the tank's bottom. Tank bottoms are only 5 or 6 mm thick, and in the last 10 years, an increasing number of leaks in tank bottoms have been reported. Tank foundations are affected by these leaks. This article describes the resulting procedure, which is used successfully in many European countries, but is not yet common in the U.S

  11. Comparative toxic effects of some xenobiotics on the germination and early seedling growth of jack pine (Pinus banksiana Lamb. ) and white birch (Betula papyrifera Marsh. )

    Weinberger, P; Vladut, R

    1981-12-01

    Seeds of jack pine (Pinus banksiana Lamb.) and white birch (Betula papyrifera Marsh.) were germinated in homogeneous emulsions or aqueous tank-mix solutions of fenitrothion or Matacil and their respective adjuvants: Atlox and Aerotex, or diluent oil No. 585 and nonylphenol. Percentage and peak germination values, water uptake, sprout length, ATP content, and morphological modifications were recorded from 0 to 14 or 21 days. Apart from 100 ppm fenitrothion which stimulated germination values, germination in jack pine was only marginally affected by any of the treatments; in contrast, white birch was negatively affected by all treatments. The most sensitive parameters of toxicity were the sprout length and ATP content after 14 days growth. Aberrant hypocotyl/root length ratios were evidenced in pine seeds after exposure to xenobiotic treatments which did not affect the germinative capacity of seeds. ATP content in the 14-day-old pine and birch seedlings was consistently higher than controls in all treatment sets. (Refs. 29).

  14. Geohydrologic Investigations and Landscape Characteristics of Areas Contributing Water to Springs, the Current River, and Jacks Fork, Ozark National Scenic Riverways, Missouri

    2009-01-01

    The Ozark National Scenic Riverways (ONSR) is a narrow corridor that stretches for approximately 134 miles along the Current River and Jacks Fork in southern Missouri. Most of the water flowing in the Current River and Jacks Fork is discharged to the rivers from springs within the ONSR, and most of the recharge area of these springs is outside the ONSR. This report describes geohydrologic investigations and landscape characteristics of areas contributing water to springs and the Current River and Jacks Fork in the ONSR. The potentiometric-surface map of the study area for 2000-07 shows that the groundwater divide extends beyond the surface-water divide in some places, notably along Logan Creek and the northeastern part of the study area, indicating interbasin transfer of groundwater between surface-water basins. A low hydraulic gradient occurs in much of the upland area west of the Current River associated with areas of high sinkhole density, which indicates the presence of a network of subsurface karst conduits. The results of a low base-flow seepage run indicate that most of the discharge in the Current River and Jacks Fork was from identified springs, and a smaller amount was from tributaries whose discharge probably originated as spring discharge, or from springs or diffuse groundwater discharge in the streambed. Results of a temperature profile conducted on an 85-mile reach of the Current River indicate that the lowest average temperatures were within or downstream from inflows of springs. A mass-balance on heat calculation of the discharge of Bass Rock Spring, a previously undescribed spring, resulted in an estimated discharge of 34.1 cubic feet per second (ft3/s), making it the sixth largest spring in the Current River Basin. The 13 springs in the study area for which recharge areas have been estimated accounted for 82 percent (867 ft3/s of 1,060 ft3/s) of the discharge of the Current River at Big Spring during the 2006 seepage run. Including discharge from

    Full Text Available Dryers heated by solar energy have been constructed and used in drying whole and half jack fruit almonds. The samples were dried during the day in direct sun and in the conventional solar dryer prepared for this purpose. Another piece of equipment was built for reception and accumulation of sun energy in a body of water, which was used as a heat source for night drying. The drying with the sun energy was compared with artificial drying. The jack fruit almonds were dried whole, half, with pellicle and without it. The storage of solar energy in water was technically viable for use in night drying. The drying by combining solar dryers in the day and night periods were completed in approximately 35 hours, and were equivalent to artificial drying between 40ºC and 70ºC. Almond cut in half and the pellicle removed reduced the drying time.Secadores com aquecimento por energia solar foram construídos e utilizados em secagens de amêndoas de jaca inteiras e em metades. As secagens no período diurno foram realizadas por exposição direta ao sol e em secador solar convencional, elaborado para este fim. Construiu-se também um equipamento para captação e acumulação de energia solar em uma massa de água, a qual foi utilizada como fonte de calor para realização de secagens no período noturno. As secagens com o uso de energia solar foram comparadas com secagens artificiais. As amêndoas de jaca foram secadas inteiras, em metades, com e sem película. O armazenamento da energia solar em corpo de água mostrou-se viável do ponto de vista técnico para utilização em secagens noturnas. As secagens combinando secadores por energia solar nos períodos diurno e noturno foram concluídas em tempos aproximados de 35 horas e equivaleram a secagens artificiais entre 40 ºC e 70 ºC. O corte das amêndoas e a retirada das películas reduziram o tempo de secagem.

    In this study, the phylogenetic trees of jacks and pompanos (Carangidae), an ecologically and morphologically diverse, globally distributed fish family, are inferred from a complete, concatenated data set of two mitochondrial (cytochrome c oxidase I, cytochrome b) loci and one nuclear (myosin heavy chain 6) locus. Maximum likelihood and Bayesian inferences are largely congruent and show a clear separation of Carangidae into the four subfamilies: Scomberoidinae, Trachinotinae, Naucratinae and Caranginae. The inclusion of the carangid sister lineages Coryphaenidae (dolphinfishes) and Rachycentridae (cobia), however, render Carangidae paraphyletic. The phylogenetic trees also show with high statistical support that the monotypic vadigo Campogramma glaycos is the sister to all other species within the Naucratinae. © 2017 The Fisheries Society of the British Isles.

    Full Text Available Aim: To investigate various biochemical components of seminal plasma in Marwari stallions and Poitou Jacks and to find out their correlation with that of the seminal characteristics. Materials and Methods: In this study, semen was collected from six Marwari stallions and six Poitou jacks aged from 4 to 6 years and with known fertility status. The semen collection from the stallions were collected during the breeding season, i.e., between the months of April and June. From the collected semen ejaculates, we estimated the values of some biochemical components, viz., total protein content, total lipid content, and enzymes such as glutamic pyruvic transaminase (GPT, glutamic oxaloacetic transaminase (GOT, alkaline phosphatase (ALP, acid phosphatase (ACP, and lactate dehydrogenase (LDH as well as concentrations of glucose, cholesterol, total calcium (Ca, and phosphorus (P and correlations among different seminal parameters were statistically examined using the Pearson correlation coefficient. Results: In this study, we found positive correlations between semen volume as well as sperm concentration and GOT, GPT, ALP and ACP for both the group stallions. Significant correlation between motility and glucose, GOT and GPT could be an indication for their role metabolism and protection against free radicals to the spermatozoa. Conclusion: Based on the results, it is concluded that there is a positive correlation between some biochemical values such as glucose, Ca, ALP, and LDH and seminal parameters which play a key role in capacitation and onward movement of the spermatozoa.

    Full Text Available [english] Aim: Jack Pro Spülung Plus (also available as “rheodol-Spülung plus” is recommended to mechanically maintain oral hygiene as part of an overall oral hygiene concept. Because Jack Pro Spülung Plus contains the active agents polihexanide and tosylchloramide sodium in concentrations below microbicidal efficacy, this study tested the hypothesis that the combination of mechanical rinsing and bacteriostatic effect surpasses the effect of mechanical rinsing alone.Method: The study was performed with 30 volunteers as a monocentric, controlled, randomized, blind, cross-over comparative study. The efficacy of the test product (active agents polihexanide 0.02–0.03% and tosylchloramide sodium 0.004–0.006% was compared to an aqueous solution of polihexanide (0.02–0.03% and to Ringer solution as negative control. The efficacy was measured as the reduction of colony forming units (cfu on buccal mucosa after aerobic and anaerobic cultivation. After determination of pre-values, the volunteers performed mouthrinsing for 30 sec with each of the 3 tested solutions. After 1, 10 and 60 minutes, cfu numbers were determined again. The reduction factor was calculated as the difference between log of the measured cfu before and after mouthrinsing with the test solution. The sampling was performed using a template with a smear area of 1 x 1 cm. Results: Using Ringer solution led to a slight mechanically-induced reduction of cfu in the oral cavity 1 min after rinsing the mouth cavity with the solution. After 10 min and 60 min, no influence on the cfu number could be detected. Using Jack pro Spülung Plus led to a bacteriostatic effect up to 60 min after mouthrinsing; 10 min and 60 min after rinsing the efficacy of Ringer solution was also significantly surpassed. The aqueous solution of polihexanide was less effective than Jack pro Spülung Plus after 10 and 60 min. Conclusion: Based on these observations, we conclude that Jack pro Spülung Plus is

    Satellite remote sensing algorithms of vegetation gross primary productivity (GPP) often include a light use efficiency (LUE) term that varies depending on meteorological constraints and biome type. LUE is defined as the carbon fixed per mole of photosynthetically active radiation (PAR) absorbed by the canopy (APAR). LUE estimated using GPP from eddy covariance data is complex and changes over short time periods as the available resources (soil moisture, light, temperature, and nitrogen) vary. An understanding of the variability in LUE will improve local to regional estimates of GPP within complex vegetated land cover types using the variety of remote sensing technologies now available. This study examines variability in LUE and GPP at a mature jack pine site within the Fluxnet-Canada BERMS (Boreal Ecosystem Research and Monitoring Sites) study area using a flux footprint model (Kljun et al. 2004) and airborne lidar data (e.g. Chasmer et al. 2006). Three separate weeks of high frequency eddy covariance data are analyzed for June, July, and August 2002 to capture changes in photosynthesis and carbon uptake through the growing season with variations in precipitation and soil moisture. Footprint estimates are derived in half-hourly resolution to provide information on the spatial and temporal variation of the sources of measured C-fluxes. Airborne lidar directly samples ground topography and vegetation structure (i.e., canopy and understory height, gaps between trees, base of canopy), and may provide information on soil moisture and drainage at the ground surface via absorbed and reflected laser pulse energy. Two questions will be addressed specific to net ecosystem productivity (NEP) of the site as a whole, including parts of the ecosystem that may not be properly represented using eddy covariance techniques. These are: 1. How does C uptake and respiration spatially and temporally vary across the jack pine site? 2. How do vegetation characteristics vary with

    Full Text Available Tabat barito (Ficus deltoidea, Jack leaf is believed could be used to treat diabetes. But more scientific data are needed. The aim of this study is to investigate  antidiabetic activity of  Tabat Barito extract by glucose tolerance method. The treatment was given in three doses (50, 100, and 200 mg/kg BW and two controls using aquoeus and glibenklamid.  Tabat barito extract was obtained by maceration and made into dry extract with addition of starch. The result showed that chemical compound of the ethanol extract were fenolic and saponin. The extract showed effects in lowering blood sugar levels with glucose tolerance methods at 30 to 60 minutes. Blood glucose levels of mice treated with the extract extract ranged between 132.60 to 258.00 mg/dL , glibenklamide ranged from 130.20 to 144.60 mg/dL, and aqua ranged between 227.60 to 260.20 mg/dL. The percentage decrease in blood sugar levels compared to controls is 32.54%.

    The general one-dimensional open-quotes log-sineclose quotes gas is defined by restricting the positive and negative charges of a two-dimensional Coulomb gas to live on a circle. Depending on charge constraints, this problem is equivalent to different boundary field theories. We study the electrically neutral case, which is equivalent to a two-dimensional free boson with an impurity cosine potential. We use two different methods: a perturbative one based on Jack symmetric functions, and a non-perturbative one based on the thermodynamic Bethe ansatz and functional relations. The first method allows us to find an explicit series expression for all coefficients in the virial expansion of the free energy and the experimentally measurable conductance. Some results for correlation functions are also presented. The second method gives an expression for the full free energy, which yields a surprising fluctuation-dissipation relation between the conductance and the free energy

    Gastrodia elata Bl. (GE) and Uncaria rhynchophylla (Miq.) Jacks (UR) are two traditional Chinese medicinal herbal drugs, used for the treatment of convulsions and epilepsy. Their antioxidant effects in vivo and their free radical scavenging effects in vitro were investigated. Epileptogenic foci in the lateral brain of the rat were induced by the injection of ferric chloride into the lateral cortex. Both extracts significantly inhibited the increase in levels of lipid peroxide in the ipsilateral cortex, at all times observed. In addition, the two extracts also induced an early increase of activity of superoxide dismutase in the mitochondrial fraction of the ipsilateral cortex. In in vitro experiments, the two extracts exhibited significant dose-dependent scavenging effects on free radicals, using electron spin resonance spectroscopy. These results suggest that the proposed antiepileptic effects of GE and UR may be attributable to the antioxidant activity of the active components in these two medicinal herbs.

    The relationship between sapwood area and foliage biomass is the basis for a lot of research on eco-phyisology. In this paper, foliage biomass change between two consecutive whorls is studied, using different variations in the pipe model theory. Linear and non-linear mixed-effect models relating foliage differences to sapwood area increments were tested to take into account whorl location, with the best fit statistics supporting the non-linear formulation. The estimated value of the exponent is 0.5130, which is significantly different from 1, the expected value given by the pipe model theory. When applied to crown stem sapwood taper, the model indicates that foliage biomass distribution influences the foliage biomass to sapwood area at crown base ratio. This result is interpreted as being the consequence of differences in the turnover rates of sapwood and foliage. More importantly, the model explains previously reported trends in jack pine sapwood area at crown base to tree foliage biomass ratio.

    The present study was conducted to identify the chemical constituents and evaluate the anti-inflammatory activity of crude ethanolic extracts of spine, skin and rind of jack fruit (Artocarpus heterophyllus) peel. Polyphenol and flavonoid contents were assessed using Folin's Ciocalteu reagent and aluminium chloride methods which revealed 316, 355 and 382 mg tannic acid equivalent/g of polyphenol and 96.7, 131.6 and 164.6 mg quercetin equivalent/g of flavonoid in spine, skin and rind, respectively. Anti-inflammatory activity of all three extracts was comparable to diclofenac in vitro and in vivo studies. Skin exhibited maximum anti-inflammatory activity, rind had preferential inhibition on Cyclooxygenase-2 and spine and skin inhibited both Cyclooxygenase-1 and 2 in vitro.

    We assessed whether the development of observational learning in jack mackerel Trachurus japonicus juveniles corresponds with that of their schooling behaviour. Schooling behaviour was quantitatively analyzed by nearest neighbour distance and separation angle in two size classes of fish, 20-mm and 40-mm in body length. Observer and non-observer fish with matching sizes were conditioned to pellets by temporarily stopping aeration. Observer fish were provided with five observation trials of other individuals feeding near an air stone when aeration was stopped. After the observation trial, fish were conditioned to pellets with the stop of aeration, and then the learning process was evaluated by the increase in the association with the feeding area when aeration was stopped. In 20-mm fish, which were at an immature stage of schooling behaviour, there was no difference in the learning process between observer and non-observer fish. In contrast, 40-mm fish were confirmed to have a well-developed schooling behaviour, and the observer learnt the feeding area more efficiently than the non-observer. This study provides evidence that observational learning develops along with the development of the social interaction. Copyright © 2013 Elsevier B.V. All rights reserved.

    Full Text Available Eurycomanone and eurycomanol are two quassinoids from the roots of Eurycoma longifolia Jack. The aim of this study was to assess the bioactivity of these compounds in Jurkat and K562 human leukemia cell models compared to peripheral blood mononuclear cells from healthy donors. Both eurycomanone and eurycomanol inhibited Jurkat and K562 cell viability and proliferation without affecting healthy cells. Interestingly, eurycomanone inhibited NF-κB signaling through inhibition of IκBα phosphorylation and upstream mitogen activated protein kinase (MAPK signaling, but not eurycomanol. In conclusion, both quassinoids present differential toxicity towards leukemia cells, and the presence of the α,β-unsaturated ketone in eurycomanone could be prerequisite for the NF-κB inhibition.

    Doxorubicin (Dox) is known as anticancer drug commonly used for cancer treatment. Eurycoma longifolia Jack or Pasakbumi was reported to have chemopreventive effect. In cancer patients, there are some dysfunctions of blood parameter, therefore some hematologic tests are needed to monitor cancer patients. In this study, the effects of combination of ethanolic extract of E. longifolia Jack (EEE) and Dox on hematologic profiles were investigated in rats injected by DMBA. Rats were divided into eight groups. Group I was normal group; Group II, rats were treated with extract dose 100 mg/kgbw; Groups III, IV, V, VI, VII and VIII, rats were treated with Dox, DMBA, DMBA+Dox, DMBA+EEE, DMBA+Dox +EEE, and Dox+EEE, respectively. DMBA administration orally was conducted twice a week for 5 weeks. At 16th week of treatments, bloods were taken from orbitalis sinus for hematologicals profile (levels of Hb, erytrocyte, hematocrite, leukocyte, MCV, MCH, and differencial leucocyte count) measurements. These data were analyzed by one way ANOVA followed by LSD test. DMBA administration significantly decreased the hematological profiles compared to the normal group, except in lymphocyte level. Rats treated with extract and extract+Dox were able to increase the hematological profile compared to rats given by DMBA only. Based on these findings it can be concluded that the combination of EEE and Dox potentially increase hematological profile of rats given by DMBA.

  15. A Change in Igneous Activity of the Jack Hills Zircon Sources ca. 3.9 Ga

    Bell, E. A.; Harrison, T. M.

    2010-12-01

    New Ti-in-zircon crystallization temperature (Txlln) data for Jack Hills zircons reveal that the tight clustering of Hadean grains around a Txlln of 680°C, possibly indicative of felsic-to-intermediate minimum melting conditions, continues to ~3.92 Ga. Between 3.92-3.82 Ga the 680°C clustering ceases and most concordant grains cluster around an apparent Txlln of 610°C. A small group of zircons with higher Txlln (~750°C), present during the Hadean, is also observed during this period. After 3.82 Ga a Hadean-like distribution resumes for ~100 Ma. This large, concordant, low-Ti group at ~3.9 Ga is statistically distinct from the Hadean distribution and appears to be unique in the Jack Hills zircon record. The existence of coeval high- and low-Ti groups suggests that two distinct zircon-forming processes are distinguishable ~3.9 Ga, unlike during the Hadean. The significant numbers of zircons with apparent Txlln below 600°C may be suggestive of subsolidus formation, since igneous units with solidii below 600°C are relatively rare. The higher-Ti group is more consistent with an intermediate to mafic igneous origin but metamorphic overprinting or subsolidus formation at granulite grade cannot be ruled out by Txlln alone. A substantial proportion of the high-Ti group display oscillatory and disrupted oscillatory zoning in cathodoluminescence images, usually indicative of igneous origins and later metamorphism, respectively; most low-Ti grains are homogeneous. Several of each group display patchy zonation indicative of metamorphic overprinting. Although several grains with apparent Txlln >600°C display oscillatory zonation, the majority of the low-Ti group do not show textural evidence for igneous origins. We interpret these results to indicate the transition from a mechanism(s) that produced dominantly 680°C apparent zircon temperatures at ca. 3.9 Ga to include a new zircon-forming process in the sediment source(s), likely a protracted period of metamorphism

  19. Evolution of conifer diterpene synthases: diterpene resin acid biosynthesis in lodgepole pine and jack pine involves monofunctional and bifunctional diterpene synthases.

    Diterpene resin acids (DRAs) are major components of pine (Pinus spp.) oleoresin. They play critical roles in conifer defense against insects and pathogens and as a renewable resource for industrial bioproducts. The core structures of DRAs are formed in secondary (i.e. specialized) metabolism via cycloisomerization of geranylgeranyl diphosphate (GGPP) by diterpene synthases (diTPSs). Previously described gymnosperm diTPSs of DRA biosynthesis are bifunctional enzymes that catalyze the initial bicyclization of GGPP followed by rearrangement of a (+)-copalyl diphosphate intermediate at two discrete class II and class I active sites. In contrast, similar diterpenes of gibberellin primary (i.e. general) metabolism are produced by the consecutive activity of two monofunctional class II and class I diTPSs. Using high-throughput transcriptome sequencing, we discovered 11 diTPS from jack pine (Pinus banksiana) and lodgepole pine (Pinus contorta). Three of these were orthologous to known conifer bifunctional levopimaradiene/abietadiene synthases. Surprisingly, two sets of orthologous PbdiTPSs and PcdiTPSs were monofunctional class I enzymes that lacked functional class II active sites and converted (+)-copalyl diphosphate, but not GGPP, into isopimaradiene and pimaradiene as major products. Diterpene profiles and transcriptome sequences of lodgepole pine and jack pine are consistent with roles for these diTPSs in DRA biosynthesis. The monofunctional class I diTPSs of DRA biosynthesis form a new clade within the gymnosperm-specific TPS-d3 subfamily that evolved from bifunctional diTPS rather than monofunctional enzymes (TPS-c and TPS-e) of gibberellin metabolism. Homology modeling suggested alterations in the class I active site that may have contributed to their functional specialization relative to other conifer diTPSs.

  20. Immune-mediated thrombocytopenia associated with angiostrongylus vasorum infection in a jack russell terrier

    2010-07-01

    Full Text Available Abstract A twenty-month-old Jack Russell terrier was presented with a four-day history of thrombocytopenia, echymotic inguinal haemorrhages, coughing and reduced exercise tolerance. Clinical examination revealed several petechial haemorrhages on the gingivae and small echymotic haemorrhages in the inguinal region, along with mild bilateral epistaxis. Haematology confirmed a platelet count of 1.0 × 10/L. Thoracic radiographs revealed a wide-spread mixed alveolar-interstitial lung pattern, apparent throughout the entire lungfield, but particularly marked within the left lung lobes. A presumptive diagnosis of immune-mediated thrombocytopenia was made and the dog was treated with vincristine and immunosuppressive doses of prednisolone. Initially anaemia developed following gastrointestinal haemorrhage; however, after symptomatic treatment the dog showed a marked clinical improvement. Evaluation for an underlying cause of the disease revealed Angiostrongylus vasorum L1 larvae on faecal analysis and treatment with fenbendazole was commenced. The dog made a full clinical recovery with all treatment was withdrawn within five weeks of diagnosis. This is the second report of immune-mediated thrombocytopenia associated with Angiostrongylus vasorum infection and it is the first to be successfully managed. The report highlights that Angiostrongylus vasorum should be considered in young dogs presented with thrombocytopenia.

    The interactive effects of soil temperature and elevated carbon dioxide on the photosynthetic functions of white birch and jack pine were investigated. Elevated carbon dioxide was found to significantly decrease the allocation of electron transport to photorespiration in both species by increasing electron allocation to Rubisco carboxylation. Photosynthetic down-regulation occurred in both species after four months in elevated carbon dioxide as evidenced by decreases in maximal carboxylation rate which were unaffected by soil temperature. 50 refs., 5 figs

    The authors present some geochemical data derived from the multielement analysis of three different types of volcanic rocks collected around Fildes Bay on King George Island, South Shetland. Volcanic rocks from Fildes Peninsula Group may be distinguished from those Marian Cove by their hydrothermal alteration. Apparently the correlation between NI ands Cr allows for the observation of the stratigraphic separation of samples of the same kind. Consequently, the correlation between Cu and As show a distinction between Marian Cove propylitised tuffites and both Brecciated Andesites and pyroclastic rock from Fildes Peninsula Group.

    Full Text Available Lipid damage evolution was analyzed in chilled Chilean jack mackerel (Trachurus murphyi previously treated with high hydrostatic pressure (HHP technology. Different pressure levels and pressure holding times were tested. In addition, fish corresponding to pre- and post-rigor mortis (RM stages were comparatively studied. Previous HHP treatment led to a marked lipid hydrolysis inhibition in chilled fish. Increasing the pressure level and pressure holding time led to a lower free fatty acid content, with the effect of pressure being more relevant. According to the analysis of different types of lipid oxidation indexes, no effect of the previous HHP treatment on the lipid oxidation development could be determined in chilled jack mackerel. Concerning the effect of the RM stage of raw fish, a higher primary and secondary lipid oxidation development was observed in fish corresponding to the post-RM condition throughout the chilled storage; although a definite effect on lipid hydrolysis could not be found.Se estudió la evolución de la alteración lipídica en jurel chileno (Trachurus murphyi refrigerado previamente tratado a altas presiones hidrostáticas (HHP.

De acuerdo con el análisis de distintos índices de oxidación, no se concluyó un efecto determinante sobre la oxidación lipídica por parte del tratamiento previo de HHP. En relación al efecto del estado de RM del pescado inicial, se observó una oxidación primaria y secundaria mayor en jurel correspondiente a la condición post-RM durante la conservación en refrigeración; sin embargo, no se detectó un efecto

    Various factors may impact the processes of diversification of a clade. In the marine realm, it has been shown that coral reef environments have promoted diversification in various fish groups. With the exception of requiem sharks, all the groups showing a higher level of diversity in reefs than in non-reef habitats have diets based predominantly on plankton, algae or benthic invertebrates. Here we explore the pattern of diversification of carangoid fishes, a clade that includes numerous piscivorous species (e.g. trevallies, jacks and dolphinfishes), using time-calibrated phylogenies as well as ecological and morphological data from both extant and fossil species. The study of carangoid morphospace suggests that reef environments played a role in their early radiation during the Eocene. However, contrary to the hypothesis of a reef-association-promoting effect, we show that habitat shifts to non-reef environments have increased the rates of morphological diversification (i.e. size and body shape) in extant carangoids. Piscivory did not have a major impact on the tempo of diversification of this group. Through the ecological radiation of carangoid fishes, we demonstrate that non-reef environments may sustain and promote processes of diversification of different marine fish groups, at least those including a large proportion of piscivorous species. © 2016 The Author(s).

    Diterpene resin acids (DRAs) are major components of pine (Pinus spp.) oleoresin. They play critical roles in conifer defense against insects and pathogens and as a renewable resource for industrial bioproducts. The core structures of DRAs are formed in secondary (i.e. specialized) metabolism via cycloisomerization of geranylgeranyl diphosphate (GGPP) by diterpene synthases (diTPSs). Previously described gymnosperm diTPSs of DRA biosynthesis are bifunctional enzymes that catalyze the initial bicyclization of GGPP followed by rearrangement of a (+)-copalyl diphosphate intermediate at two discrete class II and class I active sites. In contrast, similar diterpenes of gibberellin primary (i.e. general) metabolism are produced by the consecutive activity of two monofunctional class II and class I diTPSs. Using high-throughput transcriptome sequencing, we discovered 11 diTPS from jack pine (Pinus banksiana) and lodgepole pine (Pinus contorta). Three of these were orthologous to known conifer bifunctional levopimaradiene/abietadiene synthases. Surprisingly, two sets of orthologous PbdiTPSs and PcdiTPSs were monofunctional class I enzymes that lacked functional class II active sites and converted (+)-copalyl diphosphate, but not GGPP, into isopimaradiene and pimaradiene as major products. Diterpene profiles and transcriptome sequences of lodgepole pine and jack pine are consistent with roles for these diTPSs in DRA biosynthesis. The monofunctional class I diTPSs of DRA biosynthesis form a new clade within the gymnosperm-specific TPS-d3 subfamily that evolved from bifunctional diTPS rather than monofunctional enzymes (TPS-c and TPS-e) of gibberellin metabolism. Homology modeling suggested alterations in the class I active site that may have contributed to their functional specialization relative to other conifer diTPSs. PMID:23370714

  15. Analysis of Floating Buoy of a Wave Power Generating Jack-Up Platform Haiyuan 1

    2013-01-01

    Full Text Available The paper focuses on the performance of floating buoys of a wave power generating jack-up platform called Haiyuan 1, in order to work out the optimum designed draft and hydraulic pressure. The performance of the buoy, especially its delivered power, is an important issue in designing oscillating buoy wave energy converter. In this case, major factors affect the performance including incident wave, designed draft, and hydraulic pressure on the buoy. To find out the relationship among design draft, hydraulic pressure, and delivered power, the key point is to precisely estimate wave induced motion of the buoy. Three-dimensional theory and time domain method based on potential theory were adopted in the paper. Unlike ship and other floating structures, motion of wave energy converter (WEC buoy in wave will be weakened because of energy take-off, which will cause significant draft changing with time. Thus, draft changing should be taken into consideration as well. In addition, green water problem occurs more frequently than that in ship and other floating structures and also might the reduce delivered power. Therefore, green water problem will also be taken into account when choosing the optimum designed draft and hydraulic pressure. The calculation indicates that the optimum designed draft is 0.935 m, while the optimum designed hydraulic pressure is 30 kN.

    As part of planning for a series of field experiments where large quantities (up to 20 tons) of pressurized liquefied chlorine will be released, observations from previous chlorine field experiments are analyzed to estimate the ranges of chlorine concentrations expected at various downwind distances. In five field experiment days during the summer 2010 Jack Rabbit I (JR I) field trials, up to two tons of chlorine were released and concentrations were observed at distances, x, from 25 to 500 m. In the 1927 Lyme Bay (LB) experiments, there were four days of trials, where 3-10 tons of chlorine were released in about 15 min from the back of a ship. Concentrations were sampled at LB from four ships sailing across the cloud path at downwind distances in the range from about 350 to 3000 m. Thus, the distances from which JR I concentrations were available slightly overlapped the LB distances. One-minute arc-maximum chlorine concentrations, C (g/m3), were analyzed from four JR I trials and two LB trials. Normalized concentrations (Cu/Q) were plotted versus x (m), where u (m/s) is measured wind speed at heights of 2-10 m and Q (g/s) is continuous mass release rate. It is found that the JR I and LB Cu/Q observations smoothly merge with each other and fall along a line with approximate slope of -2 at distances beyond about 200 m (i.e., Cu/Q is proportional to x-2). At x < 200 m, where dense gas effects are more important, the slope is less (about -1.5). Most of the data points are within a factor of two of the "best-fit" line.

    Animals in social environments can enhance their learning efficiency by observing the behaviour of others. Our previous study showed that learning efficiency of schooling fish increased through the observation of the behaviour of trained demonstrator conspecifics. The present study aimed to verify the key factor of observational learning by investigating what information is important for social transmission of feeding information. A striped jack (Pseudocaranx dentex) observer was provided with one of the five observation treatments: (a) pellets observation, where pellets were dropped near the aeration in an adjacent tank; (b) responding conspecific observation, where a trained conspecific demonstrator responded to the aeration without food in the adjacent tank; (c) foraging conspecific observation, where a conspecific demonstrator foraged near the aeration in the adjacent tank; (d) nearby pellets observation, where pellets were dropped in a transparent column near the aeration in the observer tank; and (e) foraging heterospecific observation, where a filefish (Stephanolepis cirrhifer) demonstrator foraged near the aeration in the adjacent tank. The response to the aeration in these observers was compared with that of controls who did not observe any behaviour. Only individuals who observed foraging conspecifics showed a response to the aeration after observing. These results suggest that observer fish acquire feeding information not through recognition of prey items or through imitation of the demonstrator, but through the vicarious reinforcement of a conspecific for foraging.

    Uncaria rhynchophylla (Miq) Jack (UR) is one of many Chinese herbs. Our previous studies have shown that UR has both anticonvulsive and free radical-scavenging activities in kainic acid (KA)-treated rats. The aim of the present study was to use the effect of UR on activated microglia, nitric oxide synthase, and apoptotic cells to investigate its function in neuroproction in KA-treated rats. UR of 1.0 or 0.5 g/kg was orally administered for 3 days (first day, second day, and 30 min prior to KA administration on the third day), or 10 mg/kg (intraperitoneal injection, i.p.) N-nitro-L-arginine methyl ester (L-NAME) 30 min prior to KA (2 microg/2 microl) was injected into the right hippocampus region of Sprague-Dawly rats. ED1 (mouse anti rat CD68), neuronal nitric oxide synthase (nNOS), inducible nitric oxide synthase (iNOS) immunoreactive cells and apoptotic cells were observed in the hippocampus region. The results indicated that 1.0 g/kg, 0.5 g/kg of UR and 10 mg/kg of L-NAME reduced the counts of ED1, nNOS, iNOS immunoreactive cells and apoptotic cells in KA-treated rats. This study demonstrates that UR can reduce microglia activation, nNOS, iNOS and apoptosis, suggesting that UR plays a neuro-protective role against neuronal damage in KA-treated rats.

  1. High energy physics in Poland: the first 50 years

    International Nuclear Information System (INIS)

    Wroblewski, A.K.

    1993-01-01

    High energy physics in Poland started in 1933 when Stanislaw Ziemecki and Konstanty Narkiewicz-Jodko performed measurements of the latitude effect for cosmic rays. Subsequently, experiments with cosmic rays were carried out in balloon flights in a deep salt mine. Other Polish pioneers in this field were Ignacy Adamczewski, Czeslaw Bialobrzeski, Marian Miesowicz, Szczepan Szczeniowski and Jan Wesolowski. The ambitious 'Star of Poland' project of a stratospheric balloon flight to study cosmic rays up to an altitude of 30000 meters was not successful, first because of the fire accident and then of the outbreak of World War II. The destruction of laboratories during the war has slowed down the development of high energy physics in Poland by at least twelve years. However, in the late forties Marian Miesowicz started important cosmic ray studies in Cracow. In 1952 research using nuclear emulsions was initiated in Warsaw by Marian Danysz and Jerzy Pniewski. Two years later Marian Miesowicz and Jerzy Gierula began similar research in Cracow. In the late fifties Aleksander Zawadzki in Lodz started comprehensive studies of extensive air showers. Already in 1963 the number of experimental and theoretical papers on high energy physics published in Poland exceeded 100. Strong experimental and theoretical groups have been established in Cracow, Lodz and Warsaw. To supplement research with emulsions and bubble chambers the construction of electronic detectors for on-line experiments has been instituted. Thus, in the early eighties Polish high energy physicists were ready to participate in large projects such as DELPHI at LEP and ZEUS and H1 at HERA. The discovery of hypernuclei by Danysz and Pniewski in 1952 may be regarded as the most important achievement of physics in post-war Poland. (author). 108 refs, 26 figs, 1 tab

    Variations in otolith patterns, sizes and body morphometrics of jack mackerel Trachurus japonicus juveniles were investigated. Under transmitted light, translucent (W(t)) and opaque otoliths (W(o)) were detected in juveniles collected from Wakasa Bay between July 2005 and April 2006, whereas only opaque otoliths (G(o)) were detected in Goto-nada Sea individuals between May and June 2006. Three groups of juveniles were distinguished based on differences in hatch season, otolith size and growth history, and body morphometrics. As T. japonicus has different spawning seasons according to spawning grounds, each group was estimated to hatch in different waters. Juveniles with W(t) otoliths were considered to have stayed in coastal habitat longer, as the hatch area was estimated to be near Wakasa Bay. Juveniles with W(o) and G(o) otoliths appear to recruit to coastal waters at larger size, since their hatch areas were estimated to be far from each collection area. Larger otoliths of W(t) were attributed to otolith accretion after the second growth flexion, which was observed only for W(t) . Standard length of W(t) fish at the second otolith growth flexion was estimated to correspond to recruitment size to coastal rocky reefs in Wakasa Bay. Body morphometrics were correlated with otolith size after removing body size effect, suggesting that morphological variations of T. japonicus juveniles were also associated with the timing of recruitment to coastal habitat. © 2010 The Authors.

    Eurycoma longifolia jack (Tongkat Ali, Genus: Eurycoma; Family, Simaroubaceae) is one of the most popular tropical herbal plants. The plant contains a series of quassinoids, which are mainly responsible for its bitter taste. The plant extract, especially roots, are exclusively used (traditionally) for enhancing testosterone levels in men. The roots also have been used in indigenous traditional medicines for its unique anti-malarial, anti-pyretic, antiulcer, cytotoxic and aphrodisiac properties. As part of an on-going research on the bioactive compound of Eurycoma longifolia and evaluation for an optimized analysis method and parameter that influence in LC-MS analysis were carried out. Identification of the bioactive compounds was based on comparison of calculated retention time and mass spectral data with literature values. Examination of the Eurycoma longifolia sample showed some variations and differences in terms of parameters in LC-MS. However, combined method using methanol as the solvent with injection volume 1.0 μL and analysis in ultra scan mode and acetic acid as acidic modifier is the optimum method for LCMS analysis of Eurycoma longifolia because it successfully detected the optimum mass of compounds with good resolution and perfectly separated within a short analysis time.

    Full Text Available Pre-drilling was performed to reduce lateral earth pressure generated by pile foundation hydraulically jacked into expansive soil. Nineteen prestressed-precast spun concrete pile with diameter of 800 mm were penetrated into expansive soil up the depth of 40 m. Pre-drilling with diameter of 700 mm was carried out up to the depth of 12.5 m. Penetration loads required to install the piles, which was displayed on the built-in pressure panel, were recorded every 1 m interval. The load that was consisted of merely shaft friction was then used to find out the mobilized skin friction between pile shaft and its surrounding soils. The calculated mobilized skin friction was correlated to the value of Standard Penetration Test (NSPT and compared to Decourt formula. The result shows that skin friction calculated using Decourt formula relatively conservative compared to those determined from the records of field penetration. The upper bound of mobilized skin friction can be defined by modifying Decourt formula.

    Full Text Available John Fawcett’s Obi; or, Three-Finger’d Jack (1800 draws a distorted picture of the life of slaves in Jamaica. This paper investigates the ambivalence in this distortion as Fawcett creates two kinds of slaves by pitting them against each other: the loyal and obedient slaves (but still inferior vs. the superstitious-ridden and rebellious slaves deeply rooted in old traditions, thus considered inferior, uneducated, immoral and dangerous. The juxtaposition of what I call ‘anglicised’ slaves instrumentalised by the coloniser and the heathen ‘savages’ that are beyond the reach of the imperial ideology enables Fawcett to substantiate the claim that Christianity successfully promotes slaves to ‘anglicised’ mimic men/women who are then able to carry out its mission: to eradicate the pagan practice of obeah, three-finger’d Jack, and all those slaves that threaten the stability of the coloniser’s superiority. Charlie Haffner’s play Amistad Kata-Kata (1987 is about the heroism of Shengbe Pieh and his fellow slaves on board the La Amistad: on their way to the colonies they revolted, were sent to prison, tried, finally freed, and taken back home after 3 years. The paper shows how Haffner repositions the ‘Amistad trope’ in the 20th century by effacing the materiality of the body of the African slaves, thus re-evaluating the corporeality of the colonised slave in the 19th -century post-abolition debate by coming to terms with the cultural trauma postindependent African collective identity has been experiencing. The re-staging of the play by the ‘Freetong Players’ in 2007/8 commemorated the bicentenary of the abolition of the Atlantic Slave Trade, a unique opportunity to direct the attention to asserting the identity of ‘Post-European’ Africa.

    Full Text Available Abstract Background The association between patterns of pigmentation and deafness in the dog has a long-documented history, with reports dating back over one hundred years. Long suspected of having a genetic basis, the search for loci with a pronounced influence in the expression of hearing loss in the dog has yet to be successful. No studies in the dog to date have found a possible influence of a specific colour locus associated with deafness. The present study is intended to evaluate the heritability of deafness in the Jack Russell Terrier (JRT, characterize the mode of inheritance, and evaluate the existence of a sex, coat colour, or coat texture influence on the expression of sensorineural deafness. Results The estimation of heritability of deafness in the JRT was 0.22 when deafness was considered a binary (normal/deaf trait and 0.31 when deafness was considered a three-category (normal/unilateral/bilateral deafness. The influence of coat colour in the incidence of JRT deafness was statistically significant, indicating that dogs with more white are more likely to be deaf. The influence of sex or coat texture was not statistically significant in the incidence of JRT deafness. Complex segregation analysis revealed a model of a single locus with a large effect on the binary measure of hearing loss is not supported. Conclusion This is the first attempt, to our knowledge, to characterize a genetic component responsible for deafness in the JRT. The heritability of deafness in the JRT was found to be 0.22 and 0.31 considering deafness to be a two-category or three-category trait, respectively. There appears to be an influence of coat colour on the expression of deafness. In an attempt to characterize the mode of inheritance of deafness in the JRT, a model of a single locus with a large effect on hearing loss is not supported with this data. Further study is needed to determine if a single locus may be influencing deafness in the JRT. While the

  9. Burn Severity Dominates Understory Plant Community Response to Fire in Xeric Jack Pine Forests

    Directory of Open Access Journals (Sweden)

    Bradley D. Pinno

    2016-04-01

    Full Text Available Fire is the most common disturbance in northern boreal forests, and large fires are often associated with highly variable burn severities across the burnt area. We studied the understory plant community response to a range of burn severities and pre-fire stand age four growing seasons after the 2011 Richardson Fire in xeric jack pine forests of northern Alberta, Canada. Burn severity had the greatest impact on post-fire plant communities, while pre-fire stand age did not have a significant impact. Total plant species richness and cover decreased with disturbance severity, such that the greatest richness was in low severity burns (average 28 species per 1-m2 quadrat and plant cover was lowest in the high severity burns (average 16%. However, the response of individual plant groups differed. Lichens and bryophytes were most common in low severity burns and were effectively eliminated from the regenerating plant community at higher burn severities. In contrast, graminoid cover and richness were positively related to burn severity, while forbs did not respond significantly to burn severity, but were impacted by changes in soil chemistry with increased cover at pH >4.9. Our results indicate the importance of non-vascular plants to the overall plant community in this harsh environment and that the plant community is environmentally limited rather than recruitment or competition limited, as is often the case in more mesic forest types. If fire frequency and severity increase as predicted, we may see a shift in plant communities from stress-tolerant species, such as lichens and ericaceous shrubs, to more colonizing species, such as certain graminoids.

    Recent declines in productivity and tree survival have been widely observed in boreal forests. We used early warning signals (EWS) in tree ring data to anticipate premature mortality in jack pine (Pinus banksiana)—an extensive and dominant species occurring across the moisture-limited southern boreal forest in North America. We sampled tree rings from 113 living and 84 dead trees in three soil moisture regimes (subxeric, submesic, subhygric) in central Saskatchewan, Canada. We reconstructed annual increments of tree basal area to investigate (1) whether we could detect EWS related to mortality of individual trees, and (2) how water availability and tree growth history may explain the mortality warning signs. EWS were evident as punctuated changes in growth patterns prior to transition to an alternative state of reduced growth before dying. This transition was likely triggered by a combination of severe drought and insect outbreak. Higher moisture availability associated with a soil moisture gradient did not appear to reduce tree sensitivity to stress-induced mortality. Our results suggest tree rings offer considerable potential for detecting critical transitions in tree growth, which are linked to premature mortality.

    The pantropical genus Lasianthus Jack is identified for high phenotypic plasticity making traditional taxonomic identification difficult. Having some members with important medicinal properties, a precise complimentary identification through DNA barcoding is needed for species delineation. In this study, 12 samples representing six Philippine Lasianthus species were used to determine the most efficient barcoding loci among the cpDNA markers ( mat K, rbc L, rps 16, and trn T-F) and nrDNA (ITS) based on the criteria of universality, discriminatory power, and resolution of species. The results revealed that ITS has the recommended primer universality, greatest interspecific divergences, and average resolution of species. Among the cpDNA markers, mat K and rbc L are recommended but with minimal resolution of species. While trn T-F showed moderate interspecific variations and resolution of Lasianthus species, rps 16 has the lowest interspecific divergence and resolution of species. Consequently, ITS is the potential ideal DNA barcode for Lasianthus species. ITS, mat K, and rps 16 markers have the excellent amplification and sequence qualityITS marker has the highest interspecific divergence with the maximum values, followed by mat K, rbc L, trn T-F, and rps 16, respectivelyAll markers except rps 16 yielded average resolution to Lasianthus speciesITS marker is the most ideal locus in terms of excellent universality, high interspecific discriminatory ability, and average species resolution. Abbreviations used: ITS: Internal Transcribe Spacer, mat K: maturase K, rbc L: ribulose-1,5-biphospahte-carboxylase, rps 16: ribosomal protein 16 small subunit gene.

    Full Text Available Green Jacks, Caranx caballus, are distributed along the Eastern Pacific coast. In Panama, C. caballus was heavily fished around Las Perlas Archipelago to sustain local markets until 2007, when the archipelago was declared a marine protected area. This first study in Panama, analyzed a sample of 4 990 individuals from Las Perlas, obtained monthly from June 2005 to June 2006, from landings at the central fish market. Average total length was 36.1±6.4cm and optimum length 38.9cm. Approximately 68% of fish lengths were within ±10% of the optimal length but only six (15% were considered mega-spawners. The von Bertalanffy parameters describe a long-lived and fast growing species, while mortality rates revealed that C. caballus is under high fishing pressure. Standard length at which half of the population is mature was 38.8cm, and the size at which individuals matured massively, 33cm. Only 10-13% of the fish were immature. C. caballus reproduces two to three times per year, with peaks in December, April, and probably September, and recruits to the population at least twice per year. Catch per unit effort (CPUE was best predicted by minimum annual values of the Multivariate ENSO/ LNSO Index (MEI (R²=0.54. Results show that C. caballus in Pacific Panama is overfished. We recommend the raising of the minimum capture/landing size of this species in order to increase the proportion of megaspawners in the population and guarantee the sustainability of this resource.

    Tabat barito (Ficus deltoidea Jack) is a name given by Dayak Tribe who lived in Borneo-Kalimantan and it is belongs to the moraceae. Almost all of the parts of F. deltoidea plant is widely used as a medicinal property. The total flavonoid content (TFC) and antioxidant activity from cultivated and wild F. deltoidea leaves and stems extract were assessed. Total flavonoid content was estimated by using Aluminium chloride colorimetric method and expressed as catechin equivalents (mg CE g-1 extract) and the antioxidant activity by the DPPH (2,2-diphenyl-1-picryl hydrazyl) method. The content of total flavonoid of leaves and stems (430.77 and 371.80 µg CE mg-1 extract) of cultivated F. deltoidea were higher than in the wild leaves and stems (114.82 and 66.67 µg CE mg-1 extract). The IC50 of leaves extract of cultivated and wild F. deltoidea, based on the DPPH assay, has a strong antioxidant activity (34.19 and 39.31 µg mL-1 extract) as compared to stems extract. These results showed that the cultivated F. deltoidea are suitable source for medicinal properties and the leaves could be exploited as source of natural antioxidants.

    Full Text Available Com o presente trabalho, avalia-se a produção de milho verde e grão em cultivo orgânico e a massa de leguminosa no consórcio milho, feijão-de-porco, em duas épocas de cultivo. Foram realizados dois experimentos de campo, em Viçosa (MG, no período de outono/inverno e de primavera/verão. O milho e o feijão-de-porco foram semeados simultaneamente na mesma linha, espaçadas de 1m. Os tratamentos foram as densidades de feijão-de-porco, 0, 2, 4 e 6 plantas m-1 e as duas épocas de cultivo, no esquema fatorial 4 x 2, utilizando-se o delineamento de blocos casualizados, com quatro repetições. A produção de milho foi influenciada somente pela época do ano, atingindo 7,26 e 9,64 Mg ha-1 de milho verde e 5,01 e 7,46 Mg ha-1 de grãos nos cultivos de outono/inverno e primavera/verão, respectivamente. Houve efeito significativo da densidade de plantas, da época de amostragem e da época de cultivo sobre a produção de massa do adubo verde. A maior produção de biomassa de feijão-de-porco (5,07 Mg ha-1 foi obtida no final do ciclo do milho no cultivo de outono/inverno, com 4,8 plantas m-1. No cultivo de primavera/verão a produção máxima (2,95 Mg ha-1 foi obtida com 6 plantas m-1 também no final do ciclo da cultura do milho.

    Urease is an enzyme produced by microbes such as bacteria, yeast and fungi. Plants also produce this enzyme. Urease action splits urea into ammonia and carbamate. This action is having important implications in agro-chemical, medicinal and environment. Therefore there is always a constant search for new and novel compounds which could inhibit this enzyme. Here we have studied the interaction of jack bean urease (JBU) with silver nanoparticle to analyze the influence of the resultant protein corona formation on the catalytic property of JBU. Several techniques like UV-Vis, gel shift assay and CD spectroscopy have been used to characterize this interaction. Urease activity assay suggests that the protein corona formation inhibits the enzymatic action of JBU. The loss of enzymatic action could be either due to the nanoparticle blocking the active site of JBU or a conformational change in the protein. The CD spectra of JBU-AgNP complexes clearly revealed significant changes in the secondary structural composition of the JBU and this could be the reason for the loss of enzymatic activity of JBU. This study revealed an interesting observation, where the interaction of AgNP with JBU resulted destabilization of hexameric nature of JBU which is otherwise highly stable. The results of the present study could be useful in the development of nanoparticle based material for inhibiting the ureolytic activity of ureases in different fields.

    The otolith of a crevalle jack fish (caranx hippos) has been investigated by means of X-ray diffraction, X-ray absorption fine structure spectroscopy and scanning electron microscopy techniques. The results suggest that the biomineralization of otolith occurs predominantly in the aragonite phase. A detailed X-ray Rietveld analysis showed that the first shell Ca-O distances in otolith lay in the range 2.371-2.652 A, with each calcium atom coordinated to 9 oxygen atoms. While the average Ca-O distance remains same in both otolith and aragonite, certain Ca-O distances in otolith differ markedly from those in aragonite. Such difference reflects the remarkable degree of control that the protein matrix exercised over packing of calcium and carbonate ions to promote growth of rarer aragonite otolith. In view of the complex coordination chemistry of calcium in otoliths, the EXAFS analysis was limited to obtaining local atomic environment about calcium up to the first Ca-O shell. EXAFS data showed an asymmetric distribution of Ca-O bond distances with the centroid of distribution at 2.48 A, which is closer to the average Ca-O distance in aragonite than in calcite. The asymmetry in the Ca-O peak is consistent with an apparent departure of Ca-O distances from a near regular distribution, as expected of an aragonite otolith.

  20. White Anglo-Saxon hopes and black Americans' Atlantic dreams: Jack Johnson and the British boxing colour bar.

    Runstedtler, Theresa

    2010-01-01

    This article examines the controversy surrounding Jack Johnson's proposed world heavyweight title fight against the British champion Bombardier Billy Wells in London (1911). In juxtaposing African Americans' often glowing discussions of European tolerance with the actual white resistance the black champion faced in Britain, including the Home Office's eventual prohibition of the match, the article explores the period's transnational discourses of race and citizenship. Indeed, as white sportsmen on both sides of the Atlantic joined together in their search for a "White Hope" to unseat Johnson, the boxing ring became an important cultural arena for interracial debates over the political and social divisions between white citizens and nonwhite subjects. Although African Americans had high hopes for their hero's European sojourn, the British backlash against the Johnson-Wells match underscored the fact that their local experiences of racial oppression were just one facet of a much broader global problem. At the same time, the proposed prizefight also made the specter of interracial conflict in the colonies all the more tangible in the British capital, provoking public discussions about the merits of U.S. racial segregation, along with the need for white Anglo-Saxon solidarity around the world. Thus, this article not only exposes the underlying connections between American Jim Crow and the racialized fault lines of British imperialism, but it also traces the "tense and tender ties" linking U.S. and African American history with the new imperial history and postcolonial studies.

    Full Text Available Addition of jack bean (Canavalia ensiformis L. protein isolate in cake making was studied. The isolate was prepared from the beans by the method of isoelectrical point at pH 4. At low concentrations (less than 1% of the wheat flour, the addition of the protein isolate could improve the characteristics of the cake by increasing the loaf volume, decreasing the density, and softening the texture. In contrast, the addition of 1.5% tended to decrease the quality of the cake as compared to that added with 1% by decreasing the loaf volume, increasing the density, and hardening the texture. However, the more protein isolate added, the more slowly the rate of the cake staling.

    The NBR seals are used in tribological systems because they are resistance to solvent, oil and fuel. This elastomer is used in the jack pump (oil pump unit-PETROBRAS), it is located in the stuffing box. It converts the rotational movement of an electric motor to a vertical reciprocating movement to drive the pump shaft, generating a tribological contact between the polished rod and the seal, avoiding oil leakage. In this work, was developed an experimental test rig to simulate the sealing conditions of the tribological pair polished rod-seal package for a oil pumping unit in a 1:1 scale. In the experimental part of this work were used several techniques as thermal history, Scanning Electron Microscope (SEM), hardness and mass losses analysis. The friction influence on the temperature was one of the most important effect caused by the contact. The SEM analyses and the hardness losses had evidenced the damage on the surface submitted to the contact. (author)

  5. Increased air temperature during simulated autumn conditions does not increase photosynthetic carbon gain but affects the dissipation of excess energy in seedlings of the evergreen conifer Jack pine.

    Temperature and daylength act as environmental signals that determine the length of the growing season in boreal evergreen conifers. Climate change might affect the seasonal development of these trees, as they will experience naturally decreasing daylength during autumn, while at the same time warmer air temperature will maintain photosynthesis and respiration. We characterized the down-regulation of photosynthetic gas exchange and the mechanisms involved in the dissipation of energy in Jack pine (Pinus banksiana) in controlled environments during a simulated summer-autumn transition under natural conditions and conditions with altered air temperature and photoperiod. Using a factorial design, we dissected the effects of daylength and temperature. Control plants were grown at either warm summer conditions with 16-h photoperiod and 22 degrees C or conditions representing a cool autumn with 8 h/7 degrees C. To assess the impact of photoperiod and temperature on photosynthesis and energy dissipation, plants were also grown under either cold summer (16-h photoperiod/7 degrees C) or warm autumn conditions (8-h photoperiod/22 degrees C). Photosynthetic gas exchange was affected by both daylength and temperature. Assimilation and respiration rates under warm autumn conditions were only about one-half of the summer values but were similar to values obtained for cold summer and natural autumn treatments. In contrast, photosynthetic efficiency was largely determined by temperature but not by daylength. Plants of different treatments followed different strategies for dissipating excess energy. Whereas in the warm summer treatment safe dissipation of excess energy was facilitated via zeaxanthin, in all other treatments dissipation of excess energy was facilitated predominantly via increased aggregation of the light-harvesting complex of photosystem II. These differences were accompanied by a lower deepoxidation state and larger amounts of beta-carotene in the warm autumn

    The move toward evidence-based education has led to increasing numbers of randomised trials in schools. However, the literature on recruitment to non-clinical trials is relatively underdeveloped, when compared to that of clinical trials. Recruitment to school-based randomised trials is, however, challenging, even more so when the focus of the study is a sensitive issue such as sexual health. This article reflects on the challenges of recruiting post-primary schools, adolescent pupils and parents to a cluster randomised feasibility trial of a sexual-health intervention, and the strategies employed to address them. The Jack Trial was funded by the UK National Institute for Health Research. It comprised a feasibility study of an interactive film-based sexual-health intervention entitled If I Were Jack, recruiting over 800 adolescents from eight socio-demographically diverse post-primary schools in Northern Ireland. It aimed to determine the facilitators and barriers to recruitment and retention to a school-based sexual-health trial and identify optimal multi-level strategies for an effectiveness study. As part of an embedded process evaluation, we conducted semi-structured interviews and focus groups with principals, vice-principals, teachers, pupils and parents recruited to the study as well as classroom observations and a parents' survey. With reference to social learning theory, we identified a number of individual-, behavioural- and environmental-level factors that influenced recruitment. Commonly identified facilitators included perceptions of the relevance and potential benefit of the intervention to adolescents, the credibility of the organisation and individuals running the study, support offered by trial staff, and financial incentives. Key barriers were prior commitment to other research, lack of time and resources, and perceptions that the intervention was incompatible with pupil or parent needs or the school ethos. Reflecting on the methodological

    2001-01-01

    Soil carbon dioxide (CO2) emission (soil respiration), net CO2 exchange after photosynthetic uptake by ground-cover plants, and soil CO2 concentration versus depth below land surface were measured at four ages of jack pine (Pinus banksiana Lamb.) forest in central Saskatchewan. Soil respiration was smallest at a clear-cut site, largest in an 8-year-old stand, and decreased with stand age in 20-year-old and mature (60-75 years old) stands during May-September 1994 (12.1, 34.6, 31.5, and 24.9 mol C??m-2, respectively). Simulations of soil respiration at each stand based on continuously recorded soil temperature were within one standard deviation of measured flux for 48 of 52 measurement periods, but were 10%-30% less than linear interpolations of measured flux for the season. This was probably due to decreased soil respiration at night modeled by the temperature-flux relationships, but not documented by daytime chamber measurements. CO2 uptake by ground-cover plants ranged from 0 at the clear-cut site to 29, 25, and 9% of total growing season soil respiration at the 8-year, 20-year, and mature stands. CO2 concentrations were as great as 7150 ppmv in the upper 1 m of unsaturated zone and were proportional to measured soil respiration.

    Temperature and daylength act as environmental signals that determine the length of the growing season in boreal evergreen conifers. Climate change might affect the seasonal development of these trees, as they will experience naturally decreasing daylength during autumn, while at the same time warmer air temperature will maintain photosynthesis and respiration. We characterized the down-regulation of photosynthetic gas exchange and the mechanisms involved in the dissipation of energy in Jack pine (Pinus banksiana) in controlled environments during a simulated summer-autumn transition under natural conditions and conditions with altered air temperature and photoperiod. Using a factorial design, we dissected the effects of daylength and temperature. Control plants were grown at either warm summer conditions with 16-h photoperiod and 22°C or conditions representing a cool autumn with 8 h/7°C. To assess the impact of photoperiod and temperature on photosynthesis and energy dissipation, plants were also grown under either cold summer (16-h photoperiod/7°C) or warm autumn conditions (8-h photoperiod/22°C). Photosynthetic gas exchange was affected by both daylength and temperature. Assimilation and respiration rates under warm autumn conditions were only about one-half of the summer values but were similar to values obtained for cold summer and natural autumn treatments. In contrast, photosynthetic efficiency was largely determined by temperature but not by daylength. Plants of different treatments followed different strategies for dissipating excess energy. Whereas in the warm summer treatment safe dissipation of excess energy was facilitated via zeaxanthin, in all other treatments dissipation of excess energy was facilitated predominantly via increased aggregation of the light-harvesting complex of photosystem II. These differences were accompanied by a lower deepoxidation state and larger amounts of β-carotene in the warm autumn treatment as well as by changes in

    Sulfonamide derivatives serve as an important building blocks in the drug design discovery and development (4D) process. Ciprofloxacin-, sulfadiazine- and amantadine-based sulfonamides were synthesized as potent inhibitors of jack bean urease and free radical scavengers. Molecular diversity was explored and electronic factors were also examined. All 24 synthesized compounds exhibited excellent potential against urease enzyme. Compound 3e (IC 50 = 0.081 ± 0.003 µM), 6a (IC 50 = 0.0022 ± 0.0002 µM), 9e (IC 50 = 0.0250 ± 0.0007 µM) and 12d (IC 50 = 0.0266 ± 0.0021 µM) were found to be the lead compounds compared to standard (thiourea, IC 50 = 17.814 ± 0.096 µM). Molecular docking studies were performed to delineate the binding affinity of the molecules and a kinetic mechanism of enzyme inhibition was propounded. Compounds 3e , 6a and 12d exhibited a mixed type of inhibition, while derivative 9e revealed a non-competitive mode of inhibition. Compounds 12a , 12b , 12d , 12e and 12f showed excellent radical scavenging potency in comparison to the reference drug vitamin C.

    We use the Jack symmetric functions as a basis of the Fock space, and study the action of the Virasoro generators Ln. We calculate explicitly the matrix elements of Ln with respect to the Jack-basis. A combinatorial procedure which produces these matrix elements is conjectured. As a limiting case of the formula, we obtain a Pieri-type formula which represents a product of a power sum and a Jack symmetric function as a sum of Jack symmetric functions. Also, a similar expansion was found for the case when we differentiate the Jack symmetric functions with respect to power sums. As an application of our Jack-basis representation, a new diagrammatic interpretation is presented, why the singular vectors of the Virasoro algebra are proportional to the Jack symmetric functions with rectangular diagrams. We also propose a natural normalization of the singular vectors in the Verma module, and determine the coefficients which appear after bosonization in front of the Jack symmetric functions

    Narcolepsy is characterised by excessive daytime sleepiness and cataplexy and has a prevalence of 25 per 100,000. We suspect this is higher than presently seen in the Republic of Ireland. We aimed to calculate the Irish prevalence of Narcolepsy and to examine current management practices. We conducted an online survey of respiratory physicians, neurologists, paediatric neurologists, and psychiatrists with an interest in sleep disorders (73% response rate). Of this group, a total of 16 physicians managed 180 patients prior to January 2009. A clinical diagnosis alone was reached in 67 (41%) patients, the remainder by polysomnography or multiple sleep latency testing. No patients were diagnosed by cerebro-spinal fluid analysis of hypocretin levels. While 70 (42%) patients received modafanil, only 7 (4%) were treated with sodium oxybate. Even allowing for missing data it is apparent that Narcolepsy is hugely under-diagnosed in Ireland, however, current practises adhere with new international guidelines.

    2006-01-01

    Eurycoma longifolia Jack or better known in Malaysia as Tongkat Ali is an important herbal plant that owes its popularity locally and worldwide to its aphrodisiac claim and has been sought after as an essential component for the treatment of anti-malarial, anti-ulcer, anti-tumour promoting and anti-parasitic agent and also as health supplements. Quassinoids and canthin-6-one alkaloids contained in Tongkat Ali roots are the main substances having active functions for human body. Propagation is commonly done through seeds or some vegetative means such as cuttings of stems and root, grafting or layering. However, propagation by conventional method is inadequate to meet the demand due to low viability, low germination rate, delayed rooting and long life cycle. Tissue culture has been successfully applied for mass production of plantlets and extraction of many useful secondary metabolites, including pharmaceuticals, pigments and other fine chemicals. Tongkat Ali active substances have also been derived through cell culture technology but its processes need to be optimized before the product can be commercialized. Cell and organ cultures have been proven to be an efficient alternative method for biomass production due to its fast growth and stable metabolite production. In view of its potential commercial value as a plantation crop as well as to conserve its germplasm, micropropagation technique using cell culture system is an attractive method for regeneration and mass propagation.

  13. New insights about the population structure of the blue jack mackerel (Trachurus picturatus in the NE Atlantic using otolith stable isotope ratios

    Full Text Available The blue jack mackerel Trachurus picturatus is a pelagic fish widely distributed in the NE Atlantic and also found in the Mediterranean and Black Seas. It is an economically important resource in the Macaronesian islands of Azores, Madeira and Canaries, but despite its fishery value and ecological importance, fluctuations in the landings are difficult to explain since studies regarding the population dynamics, stocks structure, fish movements and habitat connectivity are inexistent. The populations of marine pelagic fishes, in particular the migratory ones, such as T. picturatus,, may be erroneously considered an homogenous population unit because they show broad geographic distributions, large population sizes and high migratory movements. Stable isotope ratios, namely δ18O and δ13C, measured by standard mass spectrometric techniques in whole otolith samples of T. picturatus adults sampled in the fishery grounds of the Islands of Azores, Madeira and Canaries, and at the Portuguese mainland (Matosinhos, Peniche and Portimão during the spring-summer of 2013 were analysed. The 18O signatures followed the general tendency taking into account the seawater temperatures of the sampling regions. 13C signatures showed however differences between the oceanic or continental origin of the fish. Both variables provided location-specific signatures. Further studies including mitochondrial and nuclear DNA studies are also been conducted to acquire new knowledge for fisheries conservation purposes.

    The roots of Eurycoma longifolia Jack are popularly sought as herbal medicinal supplements to improve libido and general health amongst the local ethnic population. The major quassinoids of E. longifolia improved spermatogenesis and fertility but toxicity studies have not been well documented. The reproductive toxicity, two generation of foetus teratology and the up-and-down acute toxicity were investigated in Sprague-Dawley rats orally treated with quassinoid-rich E. longifolia extract (TAF273). The results showed that the median lethal dose (LD50 ) of TAF273 for female and male rats was 1293 and >2000 mg/kg, respectively. Fertility index and litter size of the TAF273 treated were significantly increased when compared with those of the non-treated animals. The TAF273-treated dams decreased in percentage of pre-implantation loss, post-implantation loss and late resorption. No toxic symptoms were observed on the TAF273-treated pregnant female rats and their foetuses were normal. The no-observed adverse effect level (NOAEL) obtained from reproductive toxicity and teratology studies of TAF273 in rats was 100 mg/kg body weight/day, being more than 10-fold lower than the LD50 value. Thus, any human dose derived from converting the rat doses of 100 mg/kg and below may be considered as safe for further clinical studies. Copyright © 2013 John Wiley & Sons, Ltd.

  18. Influences of vegetation structure and elevation on CO2 uptake in a mature jack pine forest in Saskatchewan, Canada

    Eddy covariance (EC) is often used to measure the movement and direction of energy and trace gas concentrations in ecosystems. Data from EC networks are often combined with remote sensing data and ecosystem models in order to assess the spatial and temporal variability of carbon dioxide (CO 2 ) exchanges within specific areas of interest. This study presented a new method of determining changes in the structural characteristics of biomass and elevation. Lidar was used within the contours of half-hourly flux footprint areas to characterize vegetation structure and elevation. The influences of vegetation structure and elevation on CO 2 concentrations were measured by EC and Lidar measurements for 3 mature growing periods at a mature jack pine site in Saskatchewan. Mensuration data were collected over 2 periods. Meteorological, CO 2 , and H2O flux measurements were collected for 30 minute periods each day. Statistical analyses were conducted to determine the influence of meteorological variables on vegetation structure. Footprint contour lines were then layered onto the canopy height models derived by the lidar data. Multiple regression equations were used to determine net ecosystem productivity (NEP) and gross ecosystem productivity (GEP) using meteorological variables, canopy fractional cover; and elevation, as well as the results obtained from a Landsberg equation. The study showed that differences in NEP variability were influenced by differences in canopy and ground surface characteristics within the site. EC measurements underestimated gross CO 2 fluxes by 5 per cent as the biomass was lower within the immediate vicinity of the EC network. It was concluded that canopy structures and elevation are important factors for determining annual carbon balances. 36 refs., 8 tabs., 9 figs

    Pb isotope analyses have been carried out on 42 zircon grains from a Western Australian metaconglomerate using stepwise Pb-evaporation directly in the ion source of a thermal ionization mass spectrometer. The metaconglomerate is from the Archean Jack Hills Metasedimentary Belt, and is known from ion microprobe (''SHRIMP'') analyses to contain a complex zircon population with ages between 4.2 Ga and 3.1 Ga. The same complex pattern of ages is found by the Pb evaporation studies. Five grains yielded minimum crystallization ages from 4.17 Ga to 4.07 Ga. The main population appears significantly younger, having been generated at about 3.55-3.3 Ga. The agreement between the two analytical approaches confirms the SHRIMP results and demonstrates the value of the stepwise-evaporation technique in determining the age patterns of mixing zircon populations. In many of the evaporative Pb isotope records the 207/206 ratios remained constant for all evaporation steps, which we interpret as evaporation from concordant zircon phases. However, for the majority of zircons 207/206 ratios increased with increasing evaporation temperature, and usually approached constant values during evaporation at the highest temperatures. This can be attributed to mixing of different radiogenic Pb components from either crystalline zircon phases of different ages or from domains of isotopically disturbed metamict zircon. Present results confirm > 4 Ga zircon ages in the metaconglomerate from the Hack Hills and substantiate formation of crust at a very early stage in the evolution of the earth. Results also confirm a major crust-forming event 3.55-3.3 Ga ago. (orig.)

    Enhanced Geothermal System (EGS) relies on sufficient and irreversible enhancement of reservoir permeability through hydraulic stimulation and possibility of such desirable change of permeability is an open question that can undermine the universality of EGS concept. We report results of first hydraulic stimulation campaign conducted in two deep boreholes in fractured granodiorite geothermal reservoir in Pohang, Korea. Borehole PX-1, located at 4.22 km, was subjected to the injection of 3,907 m3 with flow rate of up to 18 kg/s followed by bleeding off of 1,207 m3. The borehole PX-2, located at 4.35 km, was subjected to the injection of 1,970 m3 with flow rate of up to 46 kg/sIn PX-1, a sharp distinct decline of wellhead pressure was observed at around 16 MPa of wellhead pressure which was similar to the predicted injection pressure to induce hydraulic shearing. Injectivity interpretation before and after the hydraulic shearing indicates that permanent increase of permeability was achieved by a factor of a few. In PX-2, however, injectivity was very small and hydraulic shearing was not observed due possibly to the near wellbore damage made by the remedying process of lost circulation such as using lost circulation material during drilling. Flow rate of larger than 40 kg/s was achieved at very high well head pressure of nearly 90 MPa. Hydraulic jacking, that is reversible opening and closure of fracture with change of injection pressure, was clearly observed. Although sharp increase of permeability due to fracture opening was achieved with elevated injection pressure, the increased permeability was reversed with decreased injection pressure.Two contrasting response observed in the same reservoir at two different boreholes which is apart only 600 m apart provide important implication that can be used for the stimulation strategy for EGS.This work was supported by the New and Renewable Energy Technology Development Program of the Korea Institute of Energy Technology

    In our previous study, Rhizoma Coptidis extract was found to exert more potent inhibitory effect than its major component berberine towards urease from Helicobacter pylori (HPU) and jack bean (JBU). In continuation of our work, the present study was designed to further comparatively investigate the urease inhibitory activities of five major protoberberine alkaloids in Rhizoma Coptidis, namely berberine, palmatine, coptisine, epiberberine, jateorhizine to identify the bioactive constituent, and illuminate the potential mechanism of action. Results indicated that the five protoberberine alkaloids acted as concentration-dependent inactivators of urease with IC 50 values ranging between 3.0 and 5087μM for HPU and 2.3->10,000μM for JBU, respectively. Notably, epiberberine (EB) was found to be the most potent inhibitor against both ureases with IC 50 values of 3.0±0.01μM for HPU and 2.3±0.01μM for JBU, which was more effective than the standard urease inhibitor, acetohydroxamic acid (83±0.01μM for HPU and 22±0.01μM for JBU, respectively). Further kinetic analysis revealed that the type of EB inhibition against HPU was slow-binding and uncompetitive, with K i of 10.6±0.01μM, while slow-binding and competitive against JBU with K i of 4.6±0.01μM. Addition of thiol reagents, such as l-cysteine, glutathione and dithiothreitol, significantly abolished the inhibition, while Ni 2+ competitive inhibitors, boric acid and sodium fluoride, synergetically inhibited urease with EB, indicating the obligatory role of the active site sulfhydryl group for the inhibition. In addition, binding of EB with the urease proved to be reversible, as about 65% and 90% enzymatic activity of HPU and JBU, respectively, could be restored by dithiothreitol application. These findings highlighted the potential role of Rhizoma Coptidis protoberberine alkaloids, especially EB, as a lead urease inhibitor in the treatment of diseases associated with ureolytic bacteria. Thus, EB had good

    Full Text Available The Pacific jack Caranx caninus is a common species fished by artisanal fishermen off the coast of Colima, México. During 2002, monthly samples of morphometric data and otoliths were taken to determine age and growth. Seven age groups were identified. The highest growth, 14.4 cm, takes place during the first year of life. During the second year, C. caninus grows 11.76 cm; the third year 9.61 cm; the fourth 7.85 cm; the fifth 6.41 cm and sixth year 5.24 cm. The constants of von Bertalanffy´s growth equation were: L∞ = 83.26 cm, W∞ = 18.138 g, K = 0.202, t o = -0.283 and A0.95 = 15 years. Growth curves of other species of the same genus were calculated in order to compare them with the one obtained in the present work.

    The mid-Miocene Jack Springs Tuff (JST) outcrops across the western Mina Deflection accommodation zone, west-central Nevada and into eastern California. Previously, the source location for the JST was unknown, yet recent studies northwest of Mono Lake, CA have identified a relatively un-rotated structural block in which to reference the paleomagnetic data. Although new studies have indicated that this block may be rotated up to 13º, we argue that the probable source area is located near the Bodie Hills, CA. At this site, the paleomagnetic reference direction is D = 353°, I = 43°, α95 = 7.7° (Carlson et al, 2013). Based on these data, the JST can be used to measure absolute vertical-axis rotation as well as enable reconstruction of the paleo-topography using the corrected anisotropy of magnetic susceptibility (AMS) data. A total of 19 sites were sampled to constrain Cenozoic to recent vertical axis rotation within the region and AMS experiments were conducted to determine the flow direction of the JST. Curie point estimates indicate that the JST ranges in titanium concentration from 0.042 to 1.10, indicating a low to moderate titanomagnetite phase (Akimoto, 1962). Demagnetization experiments reveal mean destructive fields of the NRM ranging between 15mT and 40mT suggesting that both multi-domain to pseudo-single domain grains are the dominant ferromagnetic phases that carry the remanence and AMS fabric. Preliminary paleomagnetic data yield stable single component demagnetization behavior for most sites that, after structural correction, indicate clockwise vertical axis rotation ranging from +20°± 10° to +60°± 11° between multiple fault blocks. The uncorrected AMS data yield oblate magnetic fabrics that can be used to infer the transport direction, source region, and paleovalley geometry of the JST. These data are tentatively interpreted to indicate west to east transport of the JST across the Mono Basin region into the Mina Deflection that was erupted and

    Characterizing the waste in underground storage tanks at the Hanford Site is accomplished by obtaining a representative core sample for analysis. Core sampling is one of the numerous techniques that have been developed for use given the environmental and field conditions at the Hanford Site. Core sampling is currently accomplished using either Push Mode Core Sample Truck No.1 or; Rotary Mode Core Sample Trucks No.2, 3 or 4. Past analysis (WHC 1994) has indicated that the Core Sample Truck (CST) leveling jacks are structurally inadequate when lateral loads are applied. WHC 1994 identifies many areas where failure could occur. All these failures are based on exceeding the allowable stresses listed in the American Institute of Steel Construction (AISC) code. The mode of failure is for the outrigger attachments to the truck frame to fail resulting in dropping of the CST and possible overturning (Ref. Ziada and Hundal, 1996). Out of level deployment of the truck can exceed the code allowable stresses in the structure. Calculations have been performed to establish limits for maintaining the truck level when lifting. The calculations and the associated limits are included in appendix A. The need for future operations of the CSTS is limited. Sampling is expected to be complete in FY-2001. Since there is limited time at risk for continued use of the CSTS with the leveling controls without correcting the structural problems, there are several design changes that could give incremental improvements to the operational safety of the CSTS with limited impact on available operating time. The improvements focus on making the truck easier to control during lifting and leveling. Not all of the tasks identified in this ETP need to be performed. Each task alone can improve the safety. This engineering task plan is the management plan document for implementing the necessary additional structural analysis. Any additional changes to meet requirements of standing orders shall require a

    The present study examines the antioxidative, hypoglycemic, and hypolipidemic activities of Artocarpus heterophyllus (jack fruit) leaf extracts (JFEs). The 70% ethanol (JFEE), n-butanol (JFBE), water (JFWE), chloroform (JFCE), and ethyl acetate (JFEAE) extracts were obtained. Both JFEE and JFBE markedly scavenge diphenylpicrylhydrazyl radical and chelate Fe+2 in vitro. A compound was isolated from JFBE and identified using 1D and 2D 1H- and 13C-NMR. The administration of JFEE or JFBE to streptozotocin (STZ)-diabetic rats significantly reduced fasting blood glucose (FBG) from 200 to 56 and 79 mg%, respectively; elevated insulin from 10.8 to 19.5 and 15.1 µU/ml, respectively; decreased lipid peroxides from 7.3 to 5.4 and 5.9 nmol/ml, respectively; decreased %glycosylated hemoglobin A1C (%HbA1C) from 6.8 to 4.5 and 5.0%, respectively; and increased total protein content from 2.5 to 6.3 and 5.7 mg%, respectively. Triglycerides (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), VLDL-C, and LDL/HDL ratio significantly declined by -37, -19, -23, -37, and -39%, respectively, in the case of JFEE; and by -31, -14, -17, -31, and -25%, respectively, in the case of JFBE; as compared to diabetic rats. HDL-C increased by +37% (JFEE) and by +11% (JFBE). Both JFEE and JFBE have shown appreciable results in decreasing FBG, lipid peroxides, %HbA1C, TC, LDL-C, and TG levels, and increasing insulin, HDL-C, and protein content. The spectrometric analysis confirmed that the flavonoid isolated from JFBE was isoquercitrin. We can conclude from this study that JFEE and JFBE exert hypoglycemic and hypolipidemic effects in STZ-diabetic rats through an antioxidative pathway that might be referred to their flavonoid contents.

    In this study, the essential oils of Orthosiphon stamineus Benth and Ficus deltoidea Jack were evaluated for their antibacterial activity against invasive oral pathogens, namely Enterococcus faecalis , Streptococcus mutans , Streptococcus mitis , Streptococcus salivarius , Aggregatibacter actinomycetemcomitans , Porphyromonas gingivalis and Fusobacterium nucleatum . Chemical composition of the oils was analyzed using gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). The antibacterial activity of the oils and their major constituents were investigated using the broth microdilution method (minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC)). Susceptibility test, anti-adhesion, anti-biofilm, checkerboard and time-kill assays were also carried out. Physiological changes of the bacterial cells after exposure to the oils were observed under the field emission scanning electron microscope (FESEM). O. stamineus and F. deltoidea oils mainly consisted of sesquiterpenoids (44.6% and 60.9%, respectively), and β-caryophyllene was the most abundant compound in both oils (26.3% and 36.3%, respectively). Other compounds present in O. stamineus were α-humulene (5.1%) and eugenol (8.1%), while α-humulene (5.5%) and germacrene D (7.7%) were dominant in F. deltoidea . The oils of both plants showed moderate to strong inhibition against all tested bacteria with MIC and MBC values ranging 0.63-2.5 mg/mL. However, none showed any inhibition on monospecies biofilms. The time-kill assay showed that combination of both oils with amoxicillin at concentrations of 1× and 2× MIC values demonstrated additive antibacterial effect. The FESEM study showed that both oils produced significant alterations on the cells of Gram-negative bacteria as they became pleomorphic and lysed. In conclusion, the study indicated that the oils of O. stamineus and F. deltoidea possessed moderate to strong antibacterial properties against the seven strains

    Octavian Paul ROTARU

    2004-02-01

    Full Text Available Due to their effectiveness in the design and development of software applications and due to their recognized advantages in terms of reusability, Component-Based Software Engineering (CBSE concepts have been arousing a great deal of interest in recent years. This paper presents and extends a component-based approach to object-oriented database systems (OODB introduced by us in [1] and [2]. Components are proposed as a new abstraction level for database system, logical partitions of the schema. In this context, the scope is introduced as an escalated property for transactions. Components are studied from the integrity, consistency, and concurrency control perspective. The main benefits of our proposed component model for OODB are the reusability of the database design, including the access statistics required for a proper query optimization, and a smooth information exchange. The integration of crosscutting concerns into the component database model using aspect-oriented techniques is also discussed. One of the main goals is to define a method for the assessment of component composition capabilities. These capabilities are restricted by the component’s interface and measured in terms of adaptability, degree of compose-ability and acceptability level. The above-mentioned metrics are extended from database components to generic software components.

    Full Text Available Scurrula ferruginea (Jack Danser is one of the mistletoe species belonging to Loranthaceae family, which grows on the branches of many deciduous trees in tropical countries. This study evaluated the antioxidant activities of S. ferruginea extracts. The cytotoxic activity of the selected extracts, which showed potent antioxidant activities, and high phenolic and flavonoid contents, were investigated in human breast cancer cell line (MDA-MB-231 and non-cancer human skin fibroblast cells (HSF-1184. The activities and characteristics varied depending on the different parts of S. ferruginea, solvent polarity, and concentrations of extracts. The stem methanol extract showed the highest amount of both phenolic (273.51 ± 4.84 mg gallic acid/g extract and flavonoid contents (163.41 ± 4.62 mg catechin/g extract and strong DPPH• radical scavenging (IC50 = 27.81 μg/mL and metal chelation activity (IC50 = 80.20 μg/mL. The stem aqueous extract showed the highest ABTS•+ scavenging ability. The stem methanol and aqueous extracts exhibited dose-dependent cytotoxic activity against MDA-MB-231 cells with IC50 of 19.27 and 50.35 μg/mL, respectively. Furthermore, the extracts inhibited the migration and colony formation of MDA-MB-231 cells in a concentration-dependent manner. Morphological observations revealed hallmark properties of apoptosis in treated cells. The methanol extract induced an increase in ROS generation and mitochondrial depolarization in MDA-MB-231 cells, suggesting its potent apoptotic activity. The present study demonstrated that the S. ferruginea methanol extract mediated MDA-MB-231 cell growth inhibition via induction of apoptosis which was confirmed by Western blot analysis. It may be a potential anticancer agent; however, its in vivo anticancer activity needs to be investigated.

    Threemile Falls Dam (Threemile Dam), located near the town of Umatilla, is the major collection and counting point for adult salmonids returning to the Umatilla River. Returning salmon and steelhead were enumerated at Threemile Dam from August 17, 2002 to September 29, 2003. A total of 3,080 summer steelhead (Oncorhynchus mykiss); 1716 adult, 617 jack, and 1,709 subjack fall chinook (O. tshawytscha); 3,820 adult and 971 jack coho (O. kisutch); and 3,607 adult and 135 jack spring chinook (O. tshawytscha) were counted. All fish were enumerated at the east bank facility. Of the fish counted, 6 summer steelhead and 330 adult and 49 jack spring chinook were hauled upstream from Threemile Dam. There were 2,882 summer steelhead; 1161 adult, 509 jack and 1,546 subjack fall chinook; 3,704 adult and 915 jack coho; and 2,406 adult and 31 jack spring chinook either released at, or allowed to volitionally migrate past, Threemile Dam. Also, 109 summer steelhead; 532 adult and 32 jack fall chinook; and 560 adult and 28 jack spring chinook were collected for brood. In addition, 282 spring chinook were collected for the outplanting efforts in the Walla Walla Basin. The Westland Canal juvenile facility (Westland), located near the town of Echo at rivermile (RM) 27, is the major collection point for outmigrating juvenile salmonids and steelhead kelts. The canal was open for 159 days between January 27 and July 4, 2003. During that period, fish were bypassed back to the river 145 days and were trapped 11 days. An estimated 205 pounds of juvenile fish were transported from Westland to the Umatilla River boat ramp (RM 0.5). Approximately 82% of the juveniles transported were salmonids. No steelhead kelts were hauled from Westland this year. The Threemile Dam west bank juvenile bypass was opened on September 16, 2002. and continued until November 1, 2002. The bypass was reopened March 3, 2003 and ran until July 3, 2003. The juvenile trap was operated by the Umatilla Passage Evaluation

Soil Pb-availability was assessed with Diethylene triamine pentaacetic acid (DTPA extraction. EDTA treated soils showed higher Pb (as PbEDTA2-, and Fe (as FeEDTA- concentrations in soil solution leading to higher uptake of these elements by the jack bean. On the other hand, it decreased the concentration of stable complexes as Pb-DOC and Fe-DOC.

    It is little-known that physicist Albert Einstein strongly held the view that ``Racism is America's worst disease.'' Einstein was active in the fight against racism from the 1930's until his death in 1955. Included among his friends were a number of important Afro-American figures, including the educator W.E.B. DuBois, the actor and basso profundo singer Paul Robeson, and the soprano Marian Anderson. Based on the authors' work ``Einstein on Race and Racism.''

    Sperm competition is prevalent and intense in many animal mating systems, and is a major force driving evolution of such mating systems. The objective of this study was to determine the effect of seminal plasma on sperm velocity of male Chinook salmon (Onchorhynchus tshawytscha), which possesses a mating system with male alternative reproductive tactics and intense sperm competition. Male Chinook salmon either adopt a small, precocious sneaking tactic (jack) or a large, dominant tactic (hooknose). To test whether the seminal plasma can effect sperm velocity amongst sperm competitors, two experiments were done whereby males were paired based upon the alternative tactic each male adopted, with the first experiment consisting of jack-hooknose pairs (N = 16) and the second experiment consisting of jack-jack and hooknose-hooknose pairs (N = 12 and 14, respectively). Within each pair, milt of each male was manipulated such that seminal plasma was removed and swapped between the males in each pair and sperm velocity was measured. Jack seminal plasma caused a significant decrease (∼11.9%) in hooknose sperm velocity while causing a significant increase in jack sperm velocity (∼7%), while alternatively, hooknose seminal plasma had no affect on sperm velocity of jack or other hooknose males. This study shows that rival seminal plasma may affect the outcome of sperm competition between males; males adopting a sneaking tactic, that spawn in a disadvantageous mating position, may be able to compensate for this deficit by being more competitive through the effects of their seminal plasma on their competitor's sperm velocity.

  12. The inverse microconglomerate test: Definition and application to the preservation of Paleoarchean to Hadean magnetizations in metasediments of the Jack Hills, Western Australia

    2016-04-01

    We introduce a new paleomagnetic field test, the inverse microconglomerate test. In contrast with traditional conglomerate tests, which target specimens that might preserve primary magnetizations, the inverse microconglomerate test focuses on magnetic carriers having unblocking temperatures less than peak metamorphic temperatures. These mineral carriers are expected to carry a consistent direction of remagnetization. Hence, the inverse microconglomerate test evaluates whether coherent magnetizations are retained on a grain/mineral scale in a given sedimentary rock sample. By defining the remagnetization direction, it also serves as a benchmark for comparison of magnetizations from other grains/minerals having unblocking temperatures higher than peak metamorphic conditions (i.e., potential primary magnetizations). We apply this new test to sediments of the Jack Hills (JH), Yilgarn craton, Western Australia. For the JH sediments we focus on fuchsite, a secondary Cr-mica that contains relict Cr-Fe spinels capable of recording remanent magnetizations. We find that JH fuchsite grains retain consistent magnetic directions at unblocking temperatures between ˜270 and 340 oC, which defines a positive test. This direction does not reproduce a nominal 1078-1070 Ma remagnetization reported by Weiss et al. (EPSL, 2015) that we interpret as an artifact of inappropriate use of averaging and statistics. The thermochemical remanent magnetization recorded by the fuchsite was most likely imparted during peak JH metamorphic conditions at ˜2650 Ma. Our inverse microconglomerate test complements a positive microconglomerate test and large scale positive conglomerate test conducted on JH cobbles (Tarduno and Cottrell, EPSL, 2013), further supporting evidence that JH zircons record Paleoarchean to Hadean primary magnetizations at high (greater than 550 oC) unblocking temperatures (Tarduno et al., Science, 2015). More generally, the new inverse microconglomerate test may aid in

    The project objectives were to design, engineer, test, and commercialize a drill bit suitable for drilling in hard rock and high temperature environments (10,000 meters) likely to be encountered in drilling enhanced geothermal wells. The goal is provide a drill bit that can aid in the increased penetration rate of three times over conventional drilling. Novatek has sought to leverage its polycrystalline diamond technology and a new conical cutter shape, known as the Stinger®, for this purpose. Novatek has developed a fixed bladed bit, known as the JackBit®, populated with both shear cutter and Stingers that is currently being tested by major drilling companies for geothermal and oil and gas applications. The JackBit concept comprises a fixed bladed bit with a center indenter, referred to as the Jack. The JackBit has been extensively tested in the lab and in the field. The JackBit has been transferred to a major bit manufacturer and oil service company. Except for the attached published reports all other information is confidential.

    Work-related asthma is a common occupational lung disease. The scope of the Fourth Jack Pepys Workshop that was held in May 2010 went beyond asthma to include discussion of other occupational airway diseases, in particular occupationally related chronic obstructive pulmonary disease (COPD) and bronchiolitis. Aspects explored included public health considerations, environmental aspects, outcome after diagnosis, prevention and surveillance, and other work-related obstructive airway diseases. Consistent methods are needed to accurately estimate the comparative burden of occupation-related airway diseases among different countries. Challenges to accomplishing this include variability in health care delivery, compensation systems, cultural contexts, and social structures. These factors can affect disease estimates, while heterogeneity in occupations and workplace exposures can affect the underlying true prevalence of morbidity. Consideration of the working environment included discussion of practical methods of limiting exposure to respiratory sensitizers, methods to predict new sensitizers before introduction into workplaces, the role of legislated exposure limits, and models to estimate relative validity of various ameliorative measures when complete avoidance of the sensitizer is not feasible. Other strategies discussed included medical surveillance measures and education, especially for young individuals with asthma and new workers about to enter the workforce. Medical outcomes after development of sensitizer-induced occupational asthma are best following earlier diagnosis and removal from further exposure, but a subset may be able to continue working safely provided that exposure is reduced under close follow-up monitoring. It was recognized that occupationally related COPD is common but underappreciated, deserving further study and prevention efforts.

    Full Text Available Eurycoma longifolia Jack (known as tongkat ali, a popular traditional herbal medicine, is a flowering plant of the family Simaroubaceae, native to Indonesia, Malaysia, Vietnam and also Cambodia, Myanmar, Laos and Thailand. E. longifolia, is one of the well-known folk medicines for aphrodisiac effects as well as intermittent fever (malaria in Asia. Decoctions of E. longifolia leaves are used for washing itches, while its fruits are used in curing dysentery. Its bark is mostly used as a vermifuge, while the taproots are used to treat high blood pressure, and the root bark is used for the treatment of diarrhea and fever. Mostly, the roots extract of E. longifolia are used as folk medicine for sexual dysfunction, aging, malaria, cancer, diabetes, anxiety, aches, constipation, exercise recovery, fever, increased energy, increased strength, leukemia, osteoporosis, stress, syphilis and glandular swelling. The roots are also used as an aphrodisiac, antibiotic, appetite stimulant and health supplement. The plant is reported to be rich in various classes of bioactive compounds such as quassinoids, canthin-6-one alkaloids, β-carboline alkaloids, triterpene tirucallane type, squalene derivatives and biphenyl neolignan, eurycolactone, laurycolactone, and eurycomalactone, and bioactive steroids. Among these phytoconstituents, quassinoids account for a major portion of the E. longifolia root phytochemicals. An acute toxicity study has found that the oral Lethal Dose 50 (LD50 of the alcoholic extract of E. longifolia in mice is between 1500–2000 mg/kg, while the oral LD50 of the aqueous extract form is more than 3000 mg/kg. Liver and renal function tests showed no adverse changes at normal daily dose and chronic use of E. longifolia. Based on established literature on health benefits of E. longifolia, it is important to focus attention on its more active constituents and the constituents’ identification, determination, further development and most

    Threemile Falls Dam (Threemile Dam), located near the town of Umatilla, is the major collection and counting point for adult salmonids returning to the Umatilla River. Returning salmon and steelhead were collected at Threemile Dam from August 30, 1996 to August 26, 1997. A total of 2,477 summer steelhead (Oncorhynchus mykiss); 646 adult, 80 jack, and 606 subjack fall chinook (O. tshawytscha); 618 adult and 24 jack coho (O. kisutch); and 2,194 adult and four jack spring chinook (O. tshawytscha) were collected. All fish were trapped at the east bank facility. Of the fish collected, 22 summer steelhead; 18 adult and two jack fall chinook; five adult coho; and 407 adult and three jack spring chinook were hauled upstream from Threemile Dam. There were 2,245 summer steelhead; 70 adult, 51 jack and 520 subjack fall chinook; 593 adult and 24 jack coho; and 1,130 adult spring chinook released at Threemile Dam I In addition, 110 summer steelhead; 551 adult and 25 jack fall chinook; and 600 adult spring chinook were collected for broodstock. The Westland Canal juvenile facility (Westland), located near the town of Echo at rivermile (RM) 27, is the major collection point for outmigrating juvenile salmonids and steelhead kelts, The canal was open for a total of 210 days between December 16, 1996 and July 30, 1997. During that period, fish were bypassed back to the river 175 days and were trapped on 35 days, An estimated 1,675 pounds of juvenile fish were transported from Westland to the Umatilla River boat ramp (RM 0.5), Approximately 80% of the juveniles transported were salmonids, No steelhead kelts were hauled from Westland this year. The Threemile Dam west bank juvenile bypass was operated from October 4 to November 1, 1996 and from March 26 to July 7, 1997. The juvenile trap was not operated this year. 6 refs., 6 figs., 6 tabs

    Full Text Available This paper explores women's art that interrogates the logic intrinsic to a powerful concept of maternal caring evident in Marian iconography. While conventional portrayals of women in the history of art connote maternity as divine and mystical, women's art with a feminist sensibility reconfigures the mother figure as monstrous and forbidding. Through the use of visual semiotics and Kristevan psychoanalytic theories, I analyse how feminist art reconciles sacred and sadistic states for a more aggressive mother to emerge.

    The LHC low beta quadrupoles, have very tight alignment tolerances and are located in areas with strong radiation field. They require remote re-alignment, by motorized jacks, based on the feedback of alignment sensors of each magnet. Jacks designed to support arc cryomagnets of LHC are modified and motorized with the help of adaptors. Two types of adapters, for vertical and transverse axes of the jacks, were developed and supplied through collaboration between RRCAT, DAE, India and CERN, Geneva. This paper describes their functional requirements, manufacture and quality assurance (QA). (author)

  6. Every Story Tells a Story That Has Already Been Told: Intertextuality and Intermediality in Philip Pullman’s Spring-Heeled Jack and in Kevin Brooks’ iBoy

    Michael C. Prusse

    2014-05-01

    Full Text Available Training English teachers involves acquainting them with suitable texts for their future classrooms. Ideally such texts touch upon matters that children and young adults respond to and such literature also offers learning opportunities both for the pre-service teachers and their students. It can be argued that such learning opportunities can be found when analysing superheroes, when considering the impact of the new media on young people or when focusing on the blending of different genres and texts. The two novels selected for this purpose are Philip Pullman’s Spring-Heeled Jack (1989 and Kevin Brooks’ iBoy (2010. The former is a hybrid of a traditional and a graphic novel and resorts to intertextual allusions, for instance by means of quotes at the beginning of each chapter. The latter text also resorts to quotations – but from different sources, namely almost exclusively from the worldwide web. While iBoy may at first sight look rather conventional as a novel, it nevertheless reveals its provenance from the digital age in the numbering of the chapters in the binary system. Young readers (and their teachers may thus discover the pleasures of literary reading when following Pullman’s superhero (taken from a Victorian penny-dreadful across London. Brooks’ hybrid protagonist, by contrast, a first-person narrator, allows readers to gain insights into the problematic side of his role and his powers. Ultimately these rather conventional novels succeed in capturing their readers’ attention and somewhat contradict critics who predict the arrival of a more hypertextual approach to reading because of the impact of the new media.

  13. Cannibalism, Fertility, and the Role of Food in Margaret Artwood’s The Edible Woman

    Directory of Open Access Journals (Sweden)

    Stevan Mijomanović

    2016-10-01

    Full Text Available Today we live in a world full of various temptations and sensations leading us away from ourselves. We change our Self in order to comply with society and in the process we become the Other. This paper explores how Margaret Atwood perceives the search for one’s identity and the pressure of societal roles that lead to this loss of identity. The main character in the novel The Edible Woman, Marian, goes on a conflicting journey during which she rejects herself, muses about her environment and her role in it, and tries to grasp her essence, which has become elusive. Atwood uses food imagery to portray Marian’s inner battles. In this paper we explore the implications that this food imagery has both on Marian and the contemporary reader. Atwood argues that this book is “protofeminist”, yet from the prism of contemporaneity it can be read as feminist. However, the scope of this novel stretches to other concepts relevant to the present day: obsession with ‘size zero’, following the latest trends, living in the fast lane, etc.; these concepts are depicted through metaphorical extensions such as cannibalism and fertility. Atwood masterfully sets the stage where she explores how these concepts influence an individual to the extent where one uses mimicry to fit the regulations of a capitalistic society, thus becoming almost the same but not quite (Homi Bhabha, 1984, i.e. colonization of the Self leading to an unfulfilled Other.

    Full Text Available Previously, an attempt was made to compile in a series of papers a complete bibliography of works related to physics at the University of Lviv. The period since the foundation of the University in 1661 until the division of the Chair of Physics in 1872 was discussed by Rovenchak (2014. Special attention was paid to the development of theoretical physics, starting from the first professor, Oskar Fabian (Rovenchak 2009, followed by the famous physicist Marian Smoluchowski (Rovenchak 2012, and finally the Interbellum (Rovenchak 2013. The history of astronomy at the University of Lviv, albeit without a special bibliographic section, is presented by Novosyadlyj (2011 and Apunevych et al. (2011. The development of the experimental physics since 1872 still awaits a detailed study. The present paper will provide some additions to this bibliography: firstly with the descriptions of several missing early works from the 17th and 18th century and then, with a presentation of the activity of Wojciech Urbański. It is followed by a couple of works by Oskar Fabian and Marian Smoluchowski. Finally, minor complements to the bibliographic lists from the 1930s will be made, including popular newspaper articles. We strive to present the bibliographic description as completely as possible, in particular by avoiding abbreviations in names and titles, so that readers can extract any information of their interest.

    Full Text Available The paper presents philosophical views which have been propagated in the first decade of the 20th-century by Austrian experimental physicist Franz-Serafin Exner (1846-1926. According to Exner all apparently deterministic laws are only a kind of the macroscopic limit of the indeterministic random events and processes in nature. The paper attempts to show whether Exner’s ideas have influenced the views on randomness and probability developed by renowned Polish physicist Marian Smoluchowski (1872-1917 who belonged to informal circle of Exner’s students and assistants (so-called Exner-Kreis.

    Uncaria rhynchophylla (Miq.) Jack (UR) and Gastrodia elata BI. (GE) are traditional Chinese herbs that are usually used in combination to treat convulsive disorders, such as epilepsy, in China. The aim of this study was to compare the anticonvulsive and free radical scavenging activities of UR alone and UR in combination with GE in rats. For the in vitro studies, brain tissues from 6 male Sprague-Dawley (SD) rats were treated with 120 microg/ml kainic acid (KA), with or without varied concentrations of UR or UR plus GE. For the in vivo studies, male SD rats (6 per group) received intraperitoneal (i.p.) injection of KA 12 mg/kg to induce epileptic seizures and generation of free radicals, with or without oral administration of UR 1 g/kg alone or UR 1 g/kg plus GE 1 g/kg. Epileptic seizures were verified by behavioral observations, and electroencephalography (EEG) and electromyography (EMG) recordings. These results showed that UR alone decreased KA-induced lipid peroxide levels in vitro, whereas UR plus GE did not produce a greater effect than UR alone. UR significantly reduced counts of wet dog shakes (WDS), paw tremor (PT) and facial myoclonia (FM) in KA-treated rats and significantly delayed the onset time of WDS, from 27 min in the control group to 40 min in the UR group. UR plus GE did not inhibit seizures more effectively than UR alone, but did further prolong the onset time of WDS to 63 min (P < 0.05 vs. UR alone). UR alone reduced the levels of free radicals in vivo, as measured by lipid peroxidation in the brain and luminol-chemiluminescence (CL) counts and lucigenin-CL counts in the peripheral whole blood, but the combination of GE and UR did not reduce free radical levels more markedly than UR alone. In conclusion, our results indicate that UR has anticonvulsive and free radical scavenging activities, and UR combined with GE exhibit greater inhibition on the onset time of WDS than UR alone. These findings suggest that the anticonvulsive effects of UR and

    1981-01-01

    The in-situ deformability of a highly jointed basalt rock mass was determined by two distinctly different methods: one, by the NX-borehole jack method where the displacements of opposing curved platens were related to the applied hydraulic pressures, and; two, by the modified Goodman jack method where the tangential strains on the borehole walls were related to the induced tangential stresses. The modulus obtained by the modified Goodman jack method were much higher than those obtained by the NX-borehole jack method. To explain the discrepancy, the influence of fractures and test variables such as depth, orientation, hole number and applied pressure on the calculated modulus of the rock mass were analyzed by factorial analysis and it was found that the orientations and depths of measurement has statistically significant effects. The in-situ deformability values obtained by non-linear regression analysis were also found comparable with other measurements and empirically predicted values for the basalt rock mass

    Full Text Available To research the sitting posture comfort evaluation method, through the example of comfort evaluation of the ergonomic seat and standard office seat, a methodology is introduced to evaluate the sitting posture comfort combining ergonomics theory. The proposed method is based on optical motion capture system, pressure sensor and JACK software, and TRC file is acquired by using EVART real-time capture software for identifying the spatial motion trail of human body. Then MATLAB software is used to analyze the human body motion data, and the sitting posture angle difference data for human body in different seats is acquired. TRC file is loaded into JACK software, and with the TAT REPORTER of JACK software, muscle force, moment of force and fatigue data, etc. are output, which are compared with the actual measured data from experiments, and ergonomics method is used for the evaluation. The result shows that the method of considering joint angles combining JACK software for data output is effective for evaluating sitting comfort.

    Full Text Available Lead (Pb is one of the main soil contaminants. It is also of difficult phytoremediation due to its low solubility and high retention on soil particles. EDTA application to soil is a strategy to increase heavy metal phytoextraction, but such chelants usually cause phytotoxicity and metal leaching side effects. Therefore, these research work objectives were to evaluate the effects of single (0.5 g kg-1 and split (0.25 + 0.25 g kg-1 EDTA application on Pb uptake by jack beans (Canavalia ensiformis L. as well as on Pb vertical movement in a Pb contaminated soil material. Two sets of experiments were carried out under greenhouse conditions: in the first one, plants were grown in 3L-pots filled with a Pb-contaminated soil to evaluate Pb uptake by plants; for the second experiment, PVC-columns (42 cm height were used to evaluate soil Pb leaching: the upper half-column (20 cm was filled up with Pb-contaminated soil (1800 mg kg-1 whereas the lower half-column (20 cm was filled with clean soil. Ten 60 mm-rainfalls with a duration of five hours were simulated by dropping distilled water on the top of columns, and leachates were collected for chemical analysis. Plants did not show any visual Pb toxicity symptoms or reduction in dry matter yield. Nevertheless, Pb uptake by jack beans regarded as total plant Pb accumulation was higher in EDTA-treated plants. Vertical Pb movement was observed mostly for the single EDTA application. EDTA addition to the soil favor Pb-phytoextraction by jack beans and the split EDTA application decrease the metal leaching, indicating less risk of environmental contamination.O chumbo (Pb é um dos principais contaminantes de solo. Os processos de remediação são dificultados devido à alta retenção do elemento às partículas do solo. A utilização do EDTA para aumentar a fitoextração dos metais do solo tem apresentado bons resultados. Contudo, os quelantes podem causar efeitos indesejáveis como a fitotoxidez e a lixivia

    Full Text Available Background: Treatment with buceng combination of Eurycoma longifolia Jack and Pimpinella alpine Molk has been proven to increase testosterone level, decrease apoptosis and caspase3 expression. Bcl2 is an antiapoptotic protein found in cytoplasm which inhibits cells apoptosis. This study was aimed to investigate the effect of buceng on Bcl2 expression on penile and prostate tissues of the rats. Methods: In this experimental study, 24 male Sprague Dawley rats of 90 days old, weighing ± 300 grams, were randomly assigned into four groups. Group A, normal rats. Group B, castrated rats and treated with buceng 100 mg/day, per oral (Cast-Bcg; Group C, castrated rats and treated with 2 ml of water as placebo against buceng (Cast-Plac. Group D, castrated rats, treated with mesterolone 6.75 mg/day, per oral, as exogenous testosterone (Cast-Mest. All rats were treated for 30 days. Manova test was used to analyze the different expression of Bcl2 among groups with significance level at p ≤ 0.05. Results: Castration was associated with significant decrease of Bcl2 expression in the penile and prostate tissues (53.0 and 50.9%, respectively compared to normal rats (82.6 and 84.2%, respectively, p < 0.001. Treatment with mesterolone reversed Bcl2 expression (77.1 and 78.1% to a near normal level. The same level of Bcl2 expression was also observed with buceng treatment (73.8 and 78.2%.Conclusion: The treatment with buceng could enhance Bcl2 expression in penile and prostate tissues, comparable to normal rats and mesterolone treated rats.

    The objective of this work was to determine, in the soil-plant system, the recovery efficiency of N derived from green manure applied on cabbage (Brassica oleracea) crop. The experiment was divided into two stages: the first one consisted of the straw production of jack bean (Canavalia ensiformis), velvet bean (Mucuna cinereum), and sorghum (Sorghum bicolor), in substrate enriched with 15 N. The second stage consisted of the application of 15 N-labeled green manure on the cabbage beds. Treatments consisted of: fresh residues of jack bean; fresh residues of velvet bean; fresh residues of sorghum; mixture of residues of jack bean, velvet bean, and sorghum at 1:1:1; and control without green manure addition. The N recovery in the soil plant system was influenced by the green manure species used, and the recovery efficiency of the N derived from the green manure legumes varied from 9 to 16%. The jack bean treatment shows a greater recovery efficiency of nitrogen and, therefore, the best synchrony of N supply, by straw decomposition, with the cabbage crop demand. (author)

    Habitat enhancement, protection and monitoring were the focus of the Resident Fisheries Program during 2001. Enhancement and protection included sloping, fencing and planting willows at sites on Diggie Creek, Clear Creek and Spring Creek. In addition, many previously constructed instream structures (rock barbs and wing dams) were repaired throughout the Fort Hall Indian Reservation (Reservation). In 2001, exclosure fences were erected on Diggie Creek (250 m barbed wire; (70 m jack), Wood Creek (500 m jack), Clear Creek (20 m jack), Ross Fork Creek (200 m jack), West Fork Creek (200 m jack)) and the Portneuf River (1 km barbed wire; 100 m jack). Jack and rail exclosure fences that had deteriorated over the past ten years were repaired at numerous areas throughout the Reservation. Physical sampling during 2001 included sediment and depth surveys (SADMS) in Big Jimmy Creek and Diggie Creek. SADMS, used to track changes in channel morphology and specifically track movements of silt through Bottoms stream systems were completed for eight and nine strata in the Big Jimmy and Diggie Creek, respectively. Baseline SADM data was collected in Diggie Creek to monitor the effects of bank sloping and revegetation on channel morphology and sediment levels through time. Water temperature was monitored (hourly) in Spring Creek, Clear Creek, Ross Fork Creek and Big Jimmy Creek. Biotic sampling included invertebrate sampling in the 200 and 300 series of Clear Creek. Fish population densities and biomass were sampled in Clear Creek 200 and 300 series. Sampling protocols were identical to methods used in past years. Numbers of fish in Clear Creek 300 series remained similar to 2000 while numbers of fish in Clear Creek 200 series dropped to near pre project levels. Salmonid fry densities were monitored near Broncho Bridge and were significantly higher than 2000. A mark-recapture study was initiated in spring 2001 to estimate numbers of spawning adults using the Head End of Spring Creek

  13. Pheromone Production by an Invasive Bark Beetle Varies with Monoterpene Composition of its Naïve Host.

    2015-06-01

    The secondary chemistry of host plants can have cascading impacts on the establishment of new insect herbivore populations, their long-term population dynamics, and their invasion potential in novel habitats. Mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae) has recently expanded its range into forests of jack pine, Pinus banksiana Lamb., in western Canada. We investigated whether variations in jack pine monoterpenes affect beetle pheromone production, as the primary components of the beetle's aggregation pheromone, (-)-trans-verbenol and anti-aggregation pheromone (-)-verbenone, are biosynthesized from the host monoterpene α-pinene. Jack pine bolts were collected from five Canadian provinces east of the beetle's current range, live D. ponderosae were introduced into them, and their monoterpene compositions were characterized. Production of (-)-trans-verbenol and (-)-verbenone emitted by beetles was measured to determine whether pheromone production varies with monoterpene composition of jack pines. Depending on particular ratios of major monoterpenes in host phloem, jack pine could be classified into three monoterpenoid groups characterized by high amounts of (+)-α-pinene, 3-carene, or a more moderate blend of monoterpenes, and beetle pheromone production varied among these groups. Specifically, beetles reared in trees characterized by high (+)-α-pinene produced the most (-)-trans-verbenol and (-)-verbenone, while beetles in trees characterized by high 3-carene produced the least. Our results indicate that pheromone production by D. ponderosae will remain a significant aspect and important predictor of its survival and persistence in the boreal forest.

    I am very much looking forward to visiting you, the family of physicists gathering for your annual APS conference. In different ways, my grandfather Enrico Fermi is a member of both our families. In this sense we are connected and share a common legacy, which I want to explore from the angle of two women inextricably involved with and affected by the Manhattan Project. One from the past and one alive now. These two women, despite a significant temporal and cultural gap share a remarkable number of traits and values. My talk will not offer a particular thesis or finding. Rather it will be about ways of seeing, including questioning unnoticed assumptions and belief systems. My grandmother Laura Fermi, modeled this for me as a youngster. She was at Enrico's side during the Manhattan Project years, yet in the dark about his work. What was it like to live in a climate of intellectually and patriotically charged enthusiasm, with an undercurrent of unspoken dread? Laura, just like most everyone else, discovered the true nature of the effort on the day the atomic bomb was dropped on Hiroshima. After the war and after Enrico's untimely death in 1954, in response to all she had experienced, Laura re-invented herself as an author and visionary, pioneering in both the environmental and handgun control movements. Marian Naranjo lives on the Santa Clara Pueblo near Los Alamos. Her ancestors dwelled on the Pajarito Plateau which encompasses the space where Los Alamos National Labs (LANL) is today. Her people, the Pueblo People have used the area's natural resources for ceremonial and survival for uncountable generations. They say, ``We are this place.'' What is it like to live on land one's families have safely occupied for thousands of years, with an undercurrent of dread at the prospect of toxic waste stream products from LANL? Like my grandmother did in her place and time, Marian builds community as an integral part of her environmental and social justice activism. She is

    1980-02-15

    A design is presented for a coal combine, equipped with two drum operational units, on whose both ends of the upper surface of the body, two coal saws are mounted with the help of a lever system. These saws, found in an operational position, form a gap in the block of the coal block, which is not embraced by the drum operational unit. The coal block, found between the gap and the support, falls down onto the longwall scraper conveyor. The lever system of each coal saw is controlled by two hydraulic jacks. One of the jacks is mounted vertically on the facial wall of the body of the combine and is used for the hoisting for the required height of the horizontal arm of the lever, reinforced by one end in the hinge on the body of the combine. On the ''free'' end of that lever, a coal saw is mounted in a hinge-like fashion and which is connected by the hydraulic jack to the horizontal arm of the lever system. This hydraulic jack is used for the clamping of the coal saw to the face.

  20. Factors influencing the quality of Myrmecia pilosula (Jack Jumper) ant venom for use in in vitro and in vivo diagnoses of allergen sensitization and in allergen immunotherapy.

    Allergen immunotherapy uses pharmaceutical preparations derived from naturally occurring source materials, which contain water-soluble allergenic components responsible for allergic reactions. The success of in vivo and in vitro diagnoses in allergen sensitization and allergen immunotherapy largely depends on the quality, composition and uniformity of allergenic materials used to produce the active ingredients, and the formulation employed to prepare finished products. We aimed to examine the factors influencing batch-to-batch consistency of Jack Jumper (Myrmecia pilosula) ant venom (JJAV) in the form of active pharmaceutical ingredient (AI) and informed whether factors such as temperature, artificial light and container materials influence the quality of JJAV AIs. We also aimed to establish handling and storage requirements of JJAV AIs to ensure preservation of allergenic activities during usage in the diagnosis of allergen sensitization and in allergen immunotherapy. The quality and consistency of JJAV AIs were analysed using a combination of bicinchoninic acid assay for total protein quantification, HPLC-UV for JJAV allergen peptides quantification, ELISA inhibition for total allergenic potency, SDS-PAGE, AU-PAGE and immunoblot for qualitative assessment of JJAV components, and Limulus Amebocyte Lysate assay for the quantification of endotoxin concentration. API-ZYM and Zymogram assays were used to probe the presence of enzymatic activities in JJAV. Pharmaceutical-grade JJAV for allergen immunotherapy has good batch-to-batch consistency. Temporary storage at 4°C and light exposure do not affect the quality of JJAV. Exposure to temperature above 40°C degrades high MW allergens in JJAV. Vials containing JJAV must be stored frozen and in upright position during long-term storage. We have identified factors, which can influence the quality and consistency of JJAV AIs, and provided a framework for appropriate handling, transporting and storage of JJAV to be used

  2. Safe, Advanced, Adaptable Isolation System Eliminates the Need for Critical Lifts

    Ginn, Starr

    2011-01-01

    The Starr Soft Support isolation system incorporates an automatically reconfigurable aircraft jack into NASA's existing 1-Hertz isolators. This enables an aircraft to float in mid-air without the need for a critical lift during ground vibration testing (GVT), significantly reducing testing risk, time, and costs. Currently incorporating the most advanced technology available, the 60,000-poundcapacity (27-metric-ton) isolation system is used for weight and measurement tests, control-surface free-play tests, and structural mode interaction tests without the need for any major reconfiguration, often saving days of time and significantly reducing labor costs. The Starr Soft Support isolation system consists of an aircraft-jacking device with three jacking points, each of which has an individual motor and accommodates up to 20,000 pounds (9 metric tons) for a total 60,000-pound (27-metric-ton) capacity. The system can be transported to the aircraft by forklift and placed at its jacking points using a pallet jack. The motors power the electric actuators, raising the aircraft above the ground until the landing gear can retract. Inflatable isolators then deploy, enabling the aircraft to float in mid-air, simulating a 1-Hertz free-free boundary condition. Inflatable isolators have been in use at NASA for years, enabling aircraft to literally float unsupported for highly accurate GVT. These isolators must be placed underneath the aircraft for this to occur. Traditionally, this is achieved by a critical lift a high-risk procedure in which a crane and flexible cord system are used to lift the aircraft. In contrast, the Starr Soft Support isolation system eliminates the need for critical lift by integrating the inflatable isolators into an aircraft jacking system. The system maintains vertical and horizontal isolating capabilities. The aircraft can be rolled onto the system, jacked up, and then the isolators can be inflated and positioned without any personnel needing to work

    Compassion is a primary catalyst motivating positive human relationships, especially of those less fortunate. Our rhythms Expand-Contract of our own non-verbal body joints movements and of the law of counter-balance, enable us to identify which of nine innate affects-emotions is directing the body's movements. With this reading, a trained person can synchronize choreography of these into fully authentic compassion between two or more persons. Primary references for this are the late Silvan S. Tomkins's four volumes "Affect Imagery Consciousness," and choreographers the late Rudolf Laban, Warren Lamb, Irmgard Bartenieff, and Marian Chace.

    In many species, males may exhibit alternative life histories to circumvent the costs of intrasexual competition and female courtship. While the evolution and underlying genetic and physiological mechanisms behind alternative reproductive tactics are well studied, there has been less consideration of the ecological factors that regulate their prevalence. Here, we examine six decades of age composition records from thirty-six populations of sockeye salmon (Oncorhynchus nerka) to quantify associations between spawning habitat characteristics and the prevalence of precocious sneakers known as 'jacks'. Jack prevalence was independent of neutral genetic structure among stream populations, but varied among habitat types and as a function of continuous geomorphic characteristics. Jacks were more common in streams relative to beaches and rivers, and their prevalence was negatively associated with stream width, depth, elevation, slope and area, but positively related to bank cover. Behavioural observations showed that jacks made greater use of banks, wood and shallows than guard males, indicating that their reproductive success depends on the availability of such refuges. Our results emphasize the role of the physical habitat in shaping reproductive tactic frequencies among populations, likely through local adaptation in response to variable fitness expectations under different geomorphic conditions. © 2017 European Society For Evolutionary Biology.

    Abstract. The occurrence of Gargaphia lunulata (Mayr (Hemiptera: Tingidae was observed in leaves of four host plants: rue (Ruta graveolens L. and jack bean (Canavalia ensiformis (L. DC in an urban residential garden, in the municipality of Rio Branco, Acre State, Brazil and Crotalaria spectabilis (L., jack bean and okra (Abelmoschus esculentus L. Moench in a greenhouse, in the municipality of Londrina, Paraná State, Brazil. The colonies were found exclusively on the abaxial face of the leaves, causing chlorosis, wilting and early senescence of the same. Because G. lunulata is considered to be an important passion fruit pest in Brazil, the planting of the mentioned plant species, in intercropping or near to passion fruit crops, would not be recommended, since they could serve as plant species inoculum to passion fruit cultivation. Therefore, the occurrence of G. lunulata associated to R. graveolens and jack bean in Acre State; and C. spectabilis, jack bean, and okra, in Paraná State is record for the first time. In addition, the present work reports the first occurrence of this tingid to the States of Acre and Paraná and reports two new hosts for this insect, R. graveolens and C. spectabillis in Brazil.

    When applying LC-MS or NMR spectroscopy in metabolomics studies, high-dimensional data are generated and effective tools for variable selection are needed in order to detect the important metabolites. Methods based on sparsity combined with PLSR have recently attracted attention in the field...... of genomics [1]. They became quickly well established in the field of statistics because a close relationship to elastic net has been established. In sparse variable selection combined with PLSR, a soft thresholding is applied on each loading weight separately.

    Post-copulatory sexual selection processes, including sperm competition and cryptic female choice (CFC), can operate based on major histocompatibility (MH) genes. We investigated sperm competition between male alternative reproductive tactics [jack (sneaker) and hooknose (guard)] of Chinook salmon (Oncorhynchus tshawytscha). Using a full factorial design, we examined in vitro competitive fertilization success of paired jack and hooknose males at three time points after sperm activation (0, 15 and 60 s) to test for male competition, CFC and time effects on male fertilization success. We also examined egg-mediated CFC at two MH genes by examining both the relationship between competitive fertilization success and MH divergence as well as inheritance patterns of MH alleles in resulting offspring. We found that jacks sired more offspring than hooknose males at 0 s post-activation; however, jack fertilization success declined over time post-activation, suggesting a trade-off between sperm speed and longevity. Enhanced fertilization success of jacks (presumably via higher sperm quality) may serve to increase sneaker tactic competitiveness relative to dominant hooknose males. We also found evidence of egg-mediated CFC (i.e. female × male interaction) influencing competitive fertilization success; however, CFC was not acting on the MH genes as we found no relationship between fertilization success and MH II β 1 or MH I α 1 divergence and we found no deviations from Mendelian inheritance of MH alleles in the offspring. Our study provides insight into evolutionary mechanisms influencing variation in male mating success within alternative reproductive tactics, thus underscoring different strategies that males can adopt to attain success. © 2017 European Society For Evolutionary Biology.

    The BOREAS TF-10 team collected tower flux and meteorological data at two sites, a fen and a young jack pine forest, near Thompson, Manitoba, Canada, as part of BOREAS. A preliminary data set was assembled in August 1993 while field testing the instrument packages, and at both sites data were collected from 15-Aug to 31-Aug. The main experimental period was in 1994, when continuous data were collected from the young jack pine site from 23-May to 20-Sep. Upon examination of the 1994 data set, it became clear that the behavior of the heat, water, and carbon dioxide fluxes throughout the whole growing season was an important scientific question, and that the 1994 data record was not sufficiently long to capture the character of the seasonal behavior of the fluxes. Thus, the young jack pine site was operated from 08-May to 07-Nov in 1996 in order to collect data from spring melt to autumn freeze-up. All variables are presented as 30-minute averages. Supporting data were also collected to describe the surface#s state and to provide the information, in association with the flux data, to build SVAT models. For the young jack pine site, these supporting data included stomatal conductance measurements. The data are stored in tabular ASCII files.

    Full Text Available The article is a review of an extensive, two-volume collection of Miłosz’s statements entitled Rosja. Widzenia transoceaniczne [Russia: Tran­soceanic Views]. The reviewer, apart from a standard presentation and evaluation of the published work, attempts to discover a deeper sense of the decision to publish, “here and now”, Miłosz’s statements on Russian issues. The collection, which rounds up previously unknown texts written between 1936 and 2004, makes it possible to understand Miłosz’s writings on Russia as a continuation of Marian Zdziechowski’s essays written between the wars, where uncompromising denunciation of the “Eastern peril” was combined with deep respect and sympathy for a Russia that was not imperial.

    1985-01-01

    An extensive campaign of in situ deformation modulus measurements was recently completed using a standard NX borehole jack. These results were obtained in a granite intrusive where spent nuclear-fuel assemblies and electrical heaters had raised the rock temperatures 10 0 C to 40 0 C above ambient. We present an analysis of temperature effects based on 41 preheat and 63 post-heat measurements in three boreholes. Using analysis of covariance statistical techniques, we found that the deformation modulus is affected by heat, loading direction, and position within the borehole. The analysis also uncovered a significant interaction between the effects of heating and loading direction. We used 123 measurements from the same boreholes to evaluate the ''Draft Standard Guide for Estimating the In Situ Modulus of Rock Masses Using the NX-Borehole Jack'' which was recently proposed by Heuze. In particular, we examined the criterion for screening measurements in those cases where contact between the jack platen and the borehole wall was incomplete. We found that the proposed screen appears to operate randomly on the data and is therefore ineffective

    2013-10-01

    In line of the development of a food composition database for Bangladesh, 10 minor indigenous fruits were analysed for their nutrient composition comprising ascorbic acid, carotenoids and mineral values. Nutrient data obtained have been compared with published data reported in different literatures, book and United States Department of Agriculture-National Nutrient Database for Standard Reference. Ascorbic acid was highest in Wood apple and lowest in Roselle. Monkey jack contained the highest amount of carotenoids, zinc and copper. Content of calcium, magnesium and phosphorous were found highest in Antidesma velutinum. Potassium was the highest in Wood apple followed by in Moneky jack. It was noted that most of the minor fruits have much higher amount of ascorbic acid than the national fruit - Jack fruit ripe, the king fruit - Mango ripe of Bangladesh and exotic fruits - Apple and Grapes. The nutrient values of these minor fruits would make awareness among the people for their mass consumption for healthy life and to grow more minor fruit trees from extinction in order to maintain biodiversity.

    2017-07-01

    Millions worldwide suffer from diseases that exhibit early warnings signs that can be detected by standard clinical-grade diagnostic tools. Unfortunately, such tools are often prohibitively expensive to the developing world leading to inadequate healthcare and high mortality rates. To address this problem, a smartphone-based pulse oximeter is presented that interfaces with the phone through the audio jack, enabling point-of-care measurements of heart rate (HR) and oxygen saturation (SpO 2 ). The device is designed to utilize existing phone resources (e.g., the processor, battery, and memory) resulting in a more portable and inexpensive diagnostic tool than standalone equivalents. By adaptively tuning the LED driving signal, the device is less dependent on phone-specific audio jack properties than prior audio jack-based work making it universally compatible with all smartphones. We demonstrate that the pulse oximeter can adaptively optimize the signal-to-noise ratio (SNR) within the power constraints of a mobile phone (<; 10mW) while maintaining high accuracy (HR error <; 3.4% and SpO 2 error <; 3.7%) against a clinical grade instrument.

  15. Alien encounter a scientific novel

    2014-01-01

    It has been nearly 100 years since the Apollo moon landings, when Jack and Vladimir, two astronauts on a mission to Venus, discover a mysterious void related to indigenous life on the planet. Subsequently more voids are detected on Earth, Mars, Titan, and, quite ominously, inside a planetoid emerging from the Kuiper belt. Jack is sent to investigate the voids in the Solar System and intercept the planetoid - which, as becomes increasingly clear, is inhabited by alien life forms. Jack and his crew will have little time to understand their alien biochemistry, abilities, behavior patterns, resilience, and technology, but also how these life forms relate to the voids. Humankind's first encounter with these exotic life forms couldn't be more fateful, becoming a race against time to save life on Earth and to reveal the true nature of the voids, which seem to be intrinsically related to life and the universe itself. In this novel, the author combines many topics related to state-of-the-art research in the field of...

  20. A kidney from hell? A nephrological view of the Whitechapel murders in 1888.

    2008-10-01

    In the poor Whitechapel district of the East End of London in the fall of 1888, at least five prostitutes were brutally murdered, and in all but one case, also mutilated. The murderer was never caught and became known by his nickname 'Jack the Ripper'. The left kidney and the uterus were cut out and taken away from one of the victims named Catherine Eddowes. A kidney was also cut out of the body from another victim, but not taken away. Two weeks later, George Lusk, president of the Whitechapel Vigilance Committee, received a small cardboard box with half of a longitudinally divided kidney and a letter entitled 'From hell' claiming that the kidney inside the box was taken from the victim. The kidney was brought to Dr Thomas Horrocks Openshaw, the Curator of the London Pathological Museum, where the kidney could be microscopically examined. The press jumped on the topic and made a circumstantial case that this kidney had been indeed torn from the body of Catherine Eddowes. According to the later memoirs of Major Henry Smith of the City Police published more than 20 years after the incident, the kidney left in the corpse of Catherine Eddowes was in an advanced stage of Bright's disease and the kidney sent to George Lusk was in exactly a similar stage. Today, the majority of criminologists believe that the kidney sent to Mr Lusk was a hoax as were other letters signed with Jack the Ripper. However, the murderer took organs from his victims, and in the case of Catherine Eddowes, the kidney. Serial killers often mutilate their victims and abscond with the removed body parts as trophies. By removing the kidney from Catherine Eddowes, Jack the Ripper may have tried to take possession of the conscience, emotions and desires of one of his victims, attributes residing in the kidney as described in the Bible. Jack the Ripper was never caught; many suspects have been suggested, and the murder series ended as suddenly as it had begun. We will never know who this mentally

  2. Action of Canavalia ensiformis in remediation of contaminated soil with sulfentrazone

    Directory of Open Access Journals (Sweden)

    João Carlos Madalão

    Full Text Available ABSTRACT This study evaluated the jack bean (Canavalia ensiformis as a potential remediator of sulfentrazone in the soil. The experiment was conducted under field conditions in a complete randomised block design. The treatments consisted of soils with and without herbicide application as well as the absence and presence of C. ensiformis cultivation associated with incorporation into the soil or the removal of shoots of C. ensiformis. Sorghum was planted as a bioindicator to evaluate the remediation efficiency of jack bean. Sulfentrazone application in areas without C. ensiformis cultivation decreased plants stands, productivity, and height of sorghum compared to treatments where C. ensiformis was cultivated. Sorghum cultivated in succession to C. ensiformis in areas contaminated with sulfentrazone resulted in dry matter production, plants numbers, productivity, and height of sorghum equivalent to uncontaminated areas. The results of this research indicate that the use of jack bean for the bioremediation of sulfentrazone treated soils would provide greater security in the planting of susceptible species in areas where this herbicide has been applied. The cultivation of C. ensiformis in contaminated areas may reduce the risk of environmental impacts caused by sulfentrazone.

  3. Deformations of temporary wooden supports used to reduce building deflections in mining areas

    Temporary supports, consisting of a stack of wooden elements and a hydraulic jack, are used in the process of removing deflections in buildings with one to three aboveground floors in mining areas. During uneven raising, the supports are loaded monotonically, unloaded and loaded cyclically. Laboratory tests were designed for the supports. For the investigated range of loads of 0 to 400 kN, under a growing load, a linear relationship exists between a load and the change in the stack length, which signifies that the deformations of wooden elements and displacements related to their mutual interactions increase proportionally. A seemingly higher stack stiffness is seen at the beginning of the unloading process and for cyclical loads, meaning that in this phase of loading, the material deformation of the wooden elements and the jack is responsible for changing the jack length in this load phase, with a negligible presence of mutual displacements of wooden elements. The support, after being unloaded, returns to the initial position and its permanent deformations are not observed. The stiffness of a temporary support decreases as the height of the stack of wooden elements increases.

    In many species, males may exhibit alternative life histories to circumvent the costs of intrasexual competition and female courtship. While the evolution and underlying genetic and physiological mechanisms behind alternative reproductive tactics are well studied, there has been less consideration of the ecological factors that regulate their prevalence. Here, we examine six decades of age composition records from thirty‐six populations of sockeye salmon (Oncorhynchus nerka) to quantify associations between spawning habitat characteristics and the prevalence of precocious sneakers known as ‘jacks’. Jack prevalence was independent of neutral genetic structure among stream populations, but varied among habitat types and as a function of continuous geomorphic characteristics. Jacks were more common in streams relative to beaches and rivers, and their prevalence was negatively associated with stream width, depth, elevation, slope and area, but positively related to bank cover. Behavioural observations showed that jacks made greater use of banks, wood and shallows than guard males, indicating that their reproductive success depends on the availability of such refuges. Our results emphasize the role of the physical habitat in shaping reproductive tactic frequencies among populations, likely through local adaptation in response to variable fitness expectations under different geomorphic conditions.

    A hydraulic type elevator is installed in relatively lower buildings as compared with a rope type elevator, but the ratio in the number of installation of the former elevator is increasing. This paper explains from its construction and features to especially various control systems for the riding comfort and safety. A direct push-up system with hydraulic jacks arranged beneath a car, and an indirect push-up system that has hydraulic jacks arranged on flank of a car and transmits the movement of a plunger via a rope are available. The latter system eliminates the need of large holes to embed hydraulic jacks. While the speed is controlled by controlling flow rates of high-pressure oil, the speed, position, acceleration and even time differential calculus of the acceleration must be controlled severely. The system uses two-step control for the through-speed and the landing speed. Different systems that have been realized may include compensation for temperatures in flow rate control valves, load pressures, and oil viscosity, from learning control to fuzzy control for psychological effects, or control of inverters in motors. 13 refs., 12 figs., 1 tab.

    Full Text Available The clearest manifestations of the castilian mentality during the Ancien Regime were related with the collective religiosity and the eternal salvation. Marian help was frecuently invoked and all the people always requeried Saints' aid. The importance of the holy works of art, the weight of the personal names and the continuous resort to the celestial court, especially to the Blessed Virgin show that it was compulsory to request the supernatural mediation in ocasions when someone needed protection. We can observe the permanences and the changes of numerous rituals of the popular piety from the Baroque times to the beginning of the rupture of the values which supported it thanks to the comparation of rural and urban areas and to the study of 10.000 wills and 500 inventories and partitions.

  12. Evaluation of species richness estimators based on quantitative performance measures and sensitivity to patchiness and sample grain size

    Data from forest herbaceous plants in a site of known species richness in Cameroon were used to test the performance of rarefaction and eight species richness estimators (ACE, ICE, Chao1, Chao2, Jack1, Jack2, Bootstrap and MM). Bias, accuracy, precision and sensitivity to patchiness and sample grain size were the evaluation criteria. An evaluation of the effects of sampling effort and patchiness on diversity estimation is also provided. Stems were identified and counted in linear series of 1-m2 contiguous square plots distributed in six habitat types. Initially, 500 plots were sampled in each habitat type. The sampling process was monitored using rarefaction and a set of richness estimator curves. Curves from the first dataset suggested adequate sampling in riparian forest only. Additional plots ranging from 523 to 2143 were subsequently added in the undersampled habitats until most of the curves stabilized. Jack1 and ICE, the non-parametric richness estimators, performed better, being more accurate and less sensitive to patchiness and sample grain size, and significantly reducing biases that could not be detected by rarefaction and other estimators. This study confirms the usefulness of non-parametric incidence-based estimators, and recommends Jack1 or ICE alongside rarefaction while describing taxon richness and comparing results across areas sampled using similar or different grain sizes. As patchiness varied across habitat types, accurate estimations of diversity did not require the same number of plots. The number of samples needed to fully capture diversity is not necessarily the same across habitats, and can only be known when taxon sampling curves have indicated adequate sampling. Differences in observed species richness between habitats were generally due to differences in patchiness, except between two habitats where they resulted from differences in abundance. We suggest that communities should first be sampled thoroughly using appropriate taxon sampling

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

    Directory of Open Access Journals (Sweden)

    Jushan Liu

    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

  14. Generalized Hermite polynomials in superspace as eigenfunctions of the supersymmetric rational CMS model

    CERN Document Server

    Desrosiers, P; Mathieu, P; Desrosiers, Patrick; Lapointe, Luc; Mathieu, Pierre

    2003-01-01

    We present two constructions of the orthogonal eigenfunctions of the supersymmetric extension of the rational Calogero-Moser-Sutherland model with harmonic confinement. These eigenfunctions are the superspace extension of the generalized Hermite (or Hi-Jack) polynomials. The conserved quantities of the rational supersymmetric model are first related to their trigonometric relatives through a similarity transformation. This leads to a simple expression for the generalized Hermite superpolynomials as a differential operator acting on the corresponding Jack superpolynomials. The second construction relies on the action of the Hamiltonian on the supermonomial basis. This translates into determinantal expressions for the Hamiltonian's eigenfunctions. As an aside, the maximal superintegrability of the supersymmetric rational Calogero-Moser-Sutherland model is demonstrated.

    2017-03-01

    Exoskeleton is a walking assistance device that improves human gait cycle through providing auxiliary force and transferring physical load to the stronger muscles. This device takes the natural state of organ and follows its natural movement. Exoskeleton functions as an auxiliary device to help those with disabilities in hip and knee such as devotees, elderly farmers and agricultural machinery operators who suffer from knee complications. In this research, an exoskeleton designed with two screw jacks at knee and hip joints. To simulate extension and flexion movements of the leg joints, bearings were used at the end of hip and knee joints. The generated torque and motion angles of these joints obtained as well as the displacement curves of screw jacks in the gait cycle. Then, the human gait cycle was simulated in stance and swing phases and the obtained torque curves were compared. The results indicated that they followed the natural circle of the generated torque in joints with a little difference from each other. The maximum displacement obtained 4 and 6 cm in hip and knee joints jack respectively. The maximum torques in hip and knee joints were generated in foot contact phase. Also the minimum torques in hip and knee joints were generated in toe off and heel off phases respectively.

    1996-01-01

    Full Text Available I examined the relationships among snow cover (api, lichen abundance, and canopy composition on the range of the Aikens Lake population of woodland caribou (Rangifer tarandus caribou in southeastern Manitoba. Percent cover of forage lichens (Cladina spp. was positively correlated with maximum total thickness and with maximum vertical hardness of api. Mixed communities of trembling aspen (Populus tremuloides, spruce (Picea spp., and balsam fir (Abies balsamea showed the most favourable nival conditions for caribou but had low lichen abundance; those dominated by jack pine (Pinus banksiana were the converse. The results suggest an energetic compromise for woodland caribou when foraging for terrestrial lichens. During winter, caribou exhibited significant selection for jack pine communities whereas mixed communities were avoided.

    The purpose of this invention is to make it possible to attach a support to variable cross-sections of workings. This goal is achieved by an arrangement where in the connecting support, which includes interconnected support sections (by advancing jacks) which contain adjustible crossbeams which are alternated with the crossbeams of the other section and are interconnected by support timbers, the supporting jacks are hinged to the crossbeams and the mobile sections of the hydraulic props, which have lateral guides and are hinged to the ends of the crossbeam and are formed from two interconnected telescopic sections, while the timber supports and the lateral guides are fastened to the adjustible crossbeams and the advance sections of the hydraulic props by horizontal hinges.

  7. Technology trends, energy prices affect worldwide rig activity

    International Nuclear Information System (INIS)

    Rappold, K.

    1995-01-01

    The major worldwide offshore rig markets have improved slightly this year, while the onshore markets generally lagged slightly. Offshore rig utilization rates have remained strong worldwide, with some areas reaching nearly 100%. Total worldwide offshore rig (jack ups, semisubmersible, drillships, submersibles, and barges) utilization was about 86%. Offshore drilling activity is driven primarily by oil and natural gas price expectations. Natural gas prices tend to drive North American offshore drilling activity, including the shallow waters in the Gulf of Mexico. International offshore drilling activity and deepwater projects in the Gulf of Mexico are more closely tied to oil prices. The paper discusses US rig count, directional drilling activity, jack up rig demand, semisubmersibles demand, rig replacement costs, and new construction

    Full Text Available This survey discusses recent studies on the history of crime and criminal law in 19th century Europe. At the same time it opens up for new perspectives on the history of crime and law – perspectives which allow us to challenge the master narrative of the modern legal state’s development. The article argues that future studies should focus on the processes that lead to legal action. Prosecution attorneys, experts (i.e. physicians and journalists are only some of the agents who participate in the dispute process in court. The structural circumstances of their actions should be analyzed in order to understand legal action as dispute process – a term which was first developed by the anthropology of law.

  5. Finite element simulations of two rock mechanics tests

    International Nuclear Information System (INIS)

    Dahlke, H.J.; Lott, S.A.

    1986-04-01

    Rock mechanics tests are performed to determine in situ stress conditions and material properties of an underground rock mass. To design stable underground facilities for the permanent storage of high-level nuclear waste, determination of these properties and conditions is a necessary first step. However, before a test and its associated equipment can be designed, the engineer needs to know the range of expected values to be measured by the instruments. Sensitivity studies by means of finite element simulations are employed in this preliminary design phase to evaluate the pertinent parameters and their effects on the proposed measurements. The simulations, of two typical rock mechanics tests, the plate bearing test and the flat-jack test, by means of the finite element analysis, are described. The plate bearing test is used to determine the rock mass deformation modulus. The flat-jack test is used to determine the in situ stress conditions of the host rock. For the plate bearing test, two finite element models are used to simulate the classic problem of a load on an elastic half space and the actual problem of a plate bearing test in an underground tunnel of circular cross section. For the flat-jack simulation, a single finite element model is used to simulate both horizontal and vertical slots. Results will be compared to closed-form solutions available in the literature

Decomposition and nutrient release was determined in nylon bags (0.2 x 0.2 m, 1 mm mesh filled with straw quantities according to the area of the bag. The experimental design was randomized blocks with four replications in split plot arrangement. The straws represented the plots and the subplots evaluation periods (0, 8, 16, 24, 40, 56, and 72 days. The residues were dried to constant weight in a forced-air oven at 65 ºC to determine the remaining dry matter, then ground and sent to a laboratory to analyze macronutrient contents. Based on the contents and remaining dry matter amounts, the remaining nutrient amounts were determined, expressed in relation to the initial amount. Non-linear models were fit to the values, choosing the best adjustment in each case. Biomass quantity, N and Ca contents and cycling of nutrient quantities was greatest in the intercropping straw. The decomposition and nutrient release speeds were also highest in millet - jack - bean intercropping straw.

  10. Physiological benefits of being small in a changing world: responses of Coho salmon (Oncorhynchus kisutch to an acute thermal challenge and a simulated capture event.

    Directory of Open Access Journals (Sweden)

    Timothy D Clark

    Full Text Available Evidence is building to suggest that both chronic and acute warm temperature exposure, as well as other anthropogenic perturbations, may select for small adult fish within a species. To shed light on this phenomenon, we investigated physiological and anatomical attributes associated with size-specific responses to an acute thermal challenge and a fisheries capture simulation (exercise+air exposure in maturing male coho salmon (Oncorhynchus kisutch. Full-size females were included for a sex-specific comparison. A size-specific response in haematology to an acute thermal challenge (from 7 to 20 °C at 3 °C h(-1 was apparent only for plasma potassium, whereby full-size males exhibited a significant increase in comparison with smaller males ('jacks'. Full-size females exhibited an elevated blood stress response in comparison with full-size males. Metabolic recovery following exhaustive exercise at 7 °C was size-specific, with jacks regaining resting levels of metabolism at 9.3 ± 0.5 h post-exercise in comparison with 12.3 ± 0.4 h for full-size fish of both sexes. Excess post-exercise oxygen consumption scaled with body mass in male fish with an exponent of b = 1.20 ± 0.08. Jacks appeared to regain osmoregulatory homeostasis faster than full-size males, and they had higher ventilation rates at 1 h post-exercise. Peak metabolic rate during post-exercise recovery scaled with body mass with an exponent of b~1, suggesting that the slower metabolic recovery in large fish was not due to limitations in diffusive or convective oxygen transport, but that large fish simply accumulated a greater 'oxygen debt' that took longer to pay back at the size-independent peak metabolic rate of ~6 mg min(-1 kg(-1. Post-exercise recovery of plasma testosterone was faster in jacks compared with full-size males, suggesting less impairment of the maturation trajectory of smaller fish. Supporting previous studies, these findings suggest that environmental change and non

    Full Text Available ABSTRACTThe Grimm Brothers’ Fairy Tales are a typical example of memetics and cultural evolution. The most known types/motifs/mems in their Children’s and Household Tales (1812 are: Little Red Cap, Little Snow White, Sleeping Beauty, Hansel and Gretel, the Wolf and the Seven Young Kids, the Frog King (or the Iron Heinrich, Thumbling, the Wishing Table, Town Musicians of Bremen etc.Purpose: Based on Jack Zipes’ theory of memetics and cultural evolution of fairy tales the article deals with translations, adaptations and retellings of Grimm’s Fairy Tales in Slovenia in the period from 1849 to 2012.Methodology/approach: Both qualitative and quantitative research methods are applied. The goal of the research was to deal with the reception of the Grimm’s Fairy Tales from the point of view of Jack Zipes’ theory of memetics and cultural evolution and to determine which fairy tales have been translated into Slovenian. The article deals with the question whether the priority was given to the most typical fairy tales that had already been translated into many other languages trying to find out if any other specific selection criteria were used. Based on the qualitative and quantitative research and on the descriptive method, Jack Zipes’ sociological theory is applied to a representative bibliography of the translations into Slovenian.Research limitation: Grimm’s fairy tales were translated into Slovenian but the authors and/or translators were either not cited or cited by initials or annotations (i.e. translated from German into Slovenian by…Many Slovenian (juvenile authors have written original texts based on Grimm’s fairy tales (i.e. Oton Župančič: Sneguljčiča /Snow White, 1900 thus combining folk tradition and originality. Originality/practical implications: The research applies the sociological theory of memetics and cultural evolution of the American scientist Jack Zipes to the reception of Grimm’s Fairy Tales in Slovenia in

    Using virtual environments to assess complex large scale human tasks provides timely and cost effective results to evaluate designs and to reduce operational risks during assembly and integration of the Space Launch System (SLS). NASA's Marshall Space Flight Center (MSFC) uses a suite of tools to conduct integrated virtual analysis during the design phase of the SLS Program. Siemens Jack is a simulation tool that allows engineers to analyze human interaction with CAD designs by placing a digital human model into the environment to test different scenarios and assess the design's compliance to human factors requirements. Engineers at MSFC are using Jack in conjunction with motion capture and virtual reality systems in MSFC's Virtual Environments Lab (VEL). The VEL provides additional capability beyond standalone Jack to record and analyze a person performing a planned task to assemble the SLS at Kennedy Space Center (KSC). The VEL integrates Vicon Blade motion capture system, Siemens Jack, Oculus Rift, and other virtual tools to perform human factors assessments. By using motion capture and virtual reality, a more accurate breakdown and understanding of how an operator will perform a task can be gained. By virtual analysis, engineers are able to determine if a specific task is capable of being safely performed by both a 5% (approx. 5ft) female and a 95% (approx. 6'1) male. In addition, the analysis will help identify any tools or other accommodations that may to help complete the task. These assessments are critical for the safety of ground support engineers and keeping launch operations on schedule. Motion capture allows engineers to save and examine human movements on a frame by frame basis, while virtual reality gives the actor (person performing a task in the VEL) an immersive view of the task environment. This presentation will discuss the need of human factors for SLS and the benefits of analyzing tasks in NASA MSFC's VEL.

  15. Sensitive but Sane: Male Visionaries and their Emotional Display in Interwar Belgium

    Directory of Open Access Journals (Sweden)

    2012-03-01

    Full Text Available When a wave of Marian apparitions swept over Belgium in 1932-1935 many ‘visionaries’ (c. 200, among them a remarkably high number of men, claimed to encounter the divine. Focusing on these male visionaries and their emotional expressivity, this article aims not only at contributing to a better understanding of Catholic constructions of masculinity, it also accords with the increased attention for the historicity of emotions and, more specifically, for men’s emotional comportment. The male visionaries present a particularly interesting case since they had to live up to multiple expectations about their emotions. Whereas their visibility and trustworthiness as visionaries were founded on their capacity to display their emotions (in accordance with a tradition of emotional mysticism, these men also had to show ‘masculine’ rationality and coolness in order to provethat their experiences were not triggered by exaggerated piety or neurosis.

    2014-01-01

    Despite the wide spread use of operant conditioning within marine animal training, relatively little is known about this unique application of behavioral technology. This article explores the expansion of operant psychology to commercial marine animal training from 1955 to 1965, specifically at marine parks such as Marine Studios Florida, Marineland of the Pacific, Sea Life Park, and SeaWorld. The contributions of Keller and Marian Breland and their business Animal Behavior Enterprises (ABE) as well as other early practitioners of behavioral technology are reviewed. We also describe how operant technology was introduced and formalized into procedures that have become the cornerstone of marine animal training and entertainment. The rapid growth of the marine park industry during this time was closely linked to the spread of behavioral technology. The expansion of operant training methods within marine animal training is a unique success story of behavioral technology. © 2014 Wiley Periodicals, Inc.

    Jack London(1876-1916) is known as an American novelist in the early 20th century. He lived in the gilded times that were full of different kinds of trend of thought in literature and art. His experiences made his life more colorful. He saw the cru-elty of Capitalism and spoke for Socialism with his words. His novels, The Call of the Wild, The leading character, in their own way, witnessed the survival of the fittest in their life. Jack London told the unchanged truth—the survival of the fittest in his brilliant words. It is difficult to change the world, but easy to change oneself. One adjusts to his life space with his“evolution”, and one goes in a new environment where every cloud has a silver lining.

  4. Testing of Compact Bolted Fasteners with Insulation and Friction-Enhanced Shims for NCSX

    2009-01-01

    The fastening of the National Compact Stellarator Experiment's (NCSX) modular coils presented a number of engineering and manufacturing challenges due to the high magnetic forces, need to control induced currents, tight tolerances and restrictive space envelope. A fastening method using high strength studs, jack nuts, insulating spacers, bushings and alumina coated shims was developed which met the requirements. A test program was conducted to verify the design. The tests included measurements of flatness of the spacers, determination of contact area, torque vs. tension of the studs and jack nuts, friction coefficient tests on the alumina and G-10 insulators, electrical tests, and tension relaxation tests due to temperature excursions from room temperature to liquid nitrogen temperatures. This paper will describe the design and the results of the test program.
