    Full Text Available Herman Stein, President of the International Association of Schools of Social Work from 1968 - 1976, has for more than sixty years excelled as an educator, scholar, internationalist, university administrator, and leader in a variety of professional associations. From almost the beginning of his career, the world has been the stage on which he has played those many roles, all of them with an abundance of talent. In fact, while he was in the graduate program of what is now the Columbia University School of Social Work, he had to decide whether to become a social worker or an actor. As an undergraduate he became involved in student theatrical productions, where he teamed up with the famous comedian, Danny Kaye, who became a life-long companion and friend. At the end of Steins first year in the social work program, he was invited to join an off-Broadway variety show that helped to launch Kaye on his meteoric rise on both stage and screen. "If I´d joined," Stein has said, "the theater probably was going to be where I would make my career as a character actor." Fortunately for social work and social work education, he chose instead to continue his studies at the School of Social Work, from which he received his master's degree in 1941 and the doctoral degree in 1958. While the world has been his stage, education has been at the heart of his manifold activities. Following a period of direct service practice as a caseworker in a well-known private agency in New York City, he was recruited by the Columbia School of Social Work in 1945 as a faculty member. With an interruption for a significant overseas assignment from 1947 to 1950, he continued at Columbia for another fourteen years, rising through all professorial ranks to Professor and Director of the School's Research Center.

    The main theme of this book is the homotopy principle for holomorphic mappings from Stein manifolds to the newly introduced class of Oka manifolds. This book contains the first complete account of Oka-Grauert theory and its modern extensions, initiated by Mikhail Gromov and developed in the last decade by the author and his collaborators. Included is the first systematic presentation of the theory of holomorphic automorphisms of complex Euclidean spaces, a survey on Stein neighborhoods, connections between the geometry of Stein surfaces and Seiberg-Witten theory, and a wide variety of applicat

    Full Text Available The traveling exhibition entitled "The Steins Collect" (2011-12 again drew attention – and on this occasion in a manner perhaps more vivid than any exhibition to date – to the importance of the systematically canon-shaping work that took place in two tiny Parisian ateliers (one in the Rue de Fleurus, the other in the Rue de Madame in terms of the new painterly movements that emerged at the beginning of the 20th century. Leo, Gertrude, and Michael, three siblings from the Stein family, a family of Jewish origin from San Francisco, along with Michael's wife Sarah, not only built within the space of a few years the most important contemporary art collection in Paris, but through their lively salons came to be the most influential shapers and propagators of universal modernism, making their influence felt to this day on assessments of avant-garde art. In the course of preparations for the exhibition and the publication of the accompanying catalogue, both of which provide a comprehensive survey of the Steins' activity, light was cast on the family's Hungarian connections as well. Consequently, one painting by the Hungarian Vilmos Pelrott-Csaba was included at the American venues (San Francisco and New York of the exhibition, and a presentation on the family's ties to Hungary was held at the scholarly conference organized in connection with the exhibition. Despite the fact that several essays have been published on this subject, the written sources have not been collected – neither those dealing with the large number of Hungarians present at the Steins' Saturday evening gatherings, nor those covering the Hungarian pupils at the Académie Matisse, which was closely aligned with the Steins. This essay is a revised version of the presentation held at the Metropolitan Museum of Art in New York, supplemented with additional source-material.

    If X is an n-dimensional Stein space, it was proved that X has the homotopy type of a CW-complex of dimension≤n and in the algebraic case this was proved with the additional conclusion that the CW-complex is finite. In this paper the authors give an answer to the question if there exists a subset Q of X with the same topological properties as X, for instance Q is a strong deformation retract of X, and Q is a CW-complex of dimension≤n. 15 refs

    1998-05-01

    Full Text Available Intestine samples of Bufo sp. tadpoles with parasitism confirmed for Giardia agilis were studied by transmission electron microscopy. The G. agilis trophozoites were long and thin. The plasma membrane was sometimes undulated and the cytoplasm, adjacent to the dorsal and ventral regions, showed numerous vacuoles. The two nuclei presented prominent nucleoli. The cytoplasm was electron-dense with free ribosomes, glycogen and rough endoplasmic reticulum-like structures. Polyhedral inclusions were observed in the cytoplasm and outside the protozoan; some of these inclusions exhibited membrane disruption. The flagella ultrastructure is typical, with the caudal pair accompanied by the funis. Next to the anterior pair, osmiophilic material was noticed. The ventro-lateral flange was short and thick, supported by the marginal plates that penetrated into its distal extremity; only its distal portion had adjacent osmiophilic filament. The G. agilis trophozoites showed the general subcellular feature of the genus. However, the ventro-lateral flange ultrastructure was an intermediate type between G. muris and G. duodenalis.

    Dr. Juan Manuel Burgos proposes ″a challenge″ to whom aims to consolidate the dignity of the human person as the center of a thought structure. Burgos presents a well-founded trilogy, citing Wojtyla, Sgreccia and he himself, as a perfect combination to support personalist bioethics. However, the possibility of giving a solid anthropological support to this bioethics remains open provided that a substantial list of personalistic authors is revised. This research seeks to collate Stein's anthropological proposal to personalist bioethics needs expressed by Burgos. The study aims to prove how Stein's anthropology can be assembled to the characteristics of personalism, and thus infer that more specific levels of the personalist bioethics can be based on this anthropology.

    Critics claim that there's no connection between Gertrude Stein and mysticism, but the passages they quote to support this claim show exactly the opposite. While it may be that Stein was no Zen master, her writing discloses something about the psychology of creativity. For Stein, the creation...... of an 'other' world through writing has not only a symbolic significance but also a metaphysical one – an idea also explored by her professor at Radcliffe, William James, in his work, 'The Varieties of Religious Experience.' Stein's compositions can be said to resemble old shamanic and mystical practices...

  17. MYSTICAL ASPECT OF EDITH STEIN'S ANTHROPOLOGY: FROM PHENOMENOLOGY TO THOMISM

    Directory of Open Access Journals (Sweden)

    J. A. Shabanova

    2016-12-01

    Full Text Available The aim of the study is to find mystical elements in Edith Stein's anthropology as a connecting principle between phenomenology and Thomism. Relying on methodological definition of philosophical mystic, as a matching of theological and philosophical doctrines, based upon reflection on experience of ecstatic unity with the Absolute, it was shown that phenomenology is implicitly directed towards research of real structure of immediate experience which in all its limits approaches to mystical experience. Not the mind and not the faith, but will (that directs knowledge to mystical unity of immanent subject and transcendental object in finding the truth is defining for the mystical character of Stein's creative method. Stein, being a bright representative of phenomenology, gradually disagrees with Husserl at some points: 1. Stein considers the world as an immediate contemplation on the entity that transcends the identity of being and thinking; 2. In her opinion, phenomenology neglects the ontological Absolute. As a result, there is misplace of the Absolute by structural-cognitive aims, that, in its turn, was a reason for amalgamation of onthology and epistemology, according to Stein's views. 3. Stein strives to overcome epistemological rationality and achieve a sphere of philosophical mystic where ontological object and epistemological subject are identical in the act of mystical contemplation. 4. Lack of metaphysical elements in phenomenology leads Stein to Thomism in which she potentially seeks a way out of metaphysical limits and the way which leads to the level of transpersonal states of mind. 5. Stein reproaches transcendentalism in loss of the world and she ignores the changes in Husserl's world outlook, his transcendental turn and genealogy of the trustworthy acquaintance with the world. An empathy, as a model of extrapolation of the principle (of to be get used to the experience of the Other onto mystical act of overcoming of subject

    Highlights: Black-Right-Pointing-Pointer We proposed a hypothesis for the UV-B protective/adaptive mechanism in Euglena agilis. After moderate levels of UV-B radiation, ROS plays a signaling role to shut down photosynthetic system for protection against harmful UV radiation. Black-Right-Pointing-Pointer E. agilis exposed to excessive UV appears to become animal-like, investing all its stored energy into movement rather than into sustaining its photosynthetic machinery. Black-Right-Pointing-Pointer This adaptation allows E. agilis to avoid harmful UV and seek a safe place where the organism may regain its photosynthetic capacity for survival. - Abstract: The effects of ultraviolet B (UV-B; 295-320 nm) radiation on certain vital physiological (photosynthesis), biochemical (production of reactive oxygen species - ROS) and behavioral (motility and orientation) characteristics were investigated in the unicellular photoautotroph, Euglena agilis Carter. The photosynthetic performance of E. agilis was recorded after exposure of between 15 and 60 min followed by a period of recovery lasting 6-24 h under dim light (5-10 {mu}mol photons m{sup -2} s{sup -1}). The maximum quantum yield of PS II (F{sub v}/F{sub m}) was reduced to 65% and 14% of initial values immediately following 15 and 30 min UV-B exposure, but recovered to 100 and 86% of the initials, respectively. Values of rETR{sub max} in E. agilis exposed to 15 min UV-B were similar to those of the initials, but a 30 min UV exposure resulted in 75% reduction of rETR{sub max} with only a 43% recovery as compared with the initial after 24 h recovery. After a 60 min UV-B exposure, there were no Chl a fluorescence signals, and hence no F{sub v}/F{sub m} or rETR{sub max}. A UV dose-dependent increase in DCFH-DA fluorescence was found in E. agilis cells, reflecting an increase in ROS production. After exposures to UV-B for between 15 and 60 min, the percentages of motile cells in the population decreased to 76, 39 and 15

  5. A DG approach to the numerical solution of the Stein-Stein stochastic volatility option pricing model

    Science.gov (United States)

    Hozman, J.; Tichý, T.

    2017-12-01

    Stochastic volatility models enable to capture the real world features of the options better than the classical Black-Scholes treatment. Here we focus on pricing of European-style options under the Stein-Stein stochastic volatility model when the option value depends on the time, on the price of the underlying asset and on the volatility as a function of a mean reverting Orstein-Uhlenbeck process. A standard mathematical approach to this model leads to the non-stationary second-order degenerate partial differential equation of two spatial variables completed by the system of boundary and terminal conditions. In order to improve the numerical valuation process for a such pricing equation, we propose a numerical technique based on the discontinuous Galerkin method and the Crank-Nicolson scheme. Finally, reference numerical experiments on real market data illustrate comprehensive empirical findings on options with stochastic volatility.

    For this contribution to the special issue on "Mapping Queer Bioethics," the author offers a reflection on the nature of the literary, written word as the ethically fraught site of queer bioethics. By invoking the historical tendencies and tropes of the clinical case history alongside a seminal text by Gertrude Stein, the author at once asks if we should liberate a queer bioethics from biomedical discourse via mainstream narrative; or if we should see this strategy as unavoidably housed in narrative forms of storytelling because it echoes the tropes and stakes of the clinical, pathologized case history as regards queer sensibilities.

  7. Geographic Variation in Daily Temporal Activity Patterns of a Neotropical Marsupial (Gracilinanus agilis.

    Directory of Open Access Journals (Sweden)

    Emerson M Vieira

    Full Text Available The temporal activity of animals is an outcome of both biotic and abiotic factors, which may vary along the geographic range of the species. Therefore, studies conducted with a species in different localities with distinct features could elucidate how animals deal with such factors. In this study, we used live traps equipped with timing devices to investigate the temporal activity patterns of the didelphid Gracilinanus agilis in two dry-woodland areas of the Brazilian savanna (Cerrado. These areas were located about 660 km apart, one in Central Brazil and the other in Southeastern Brazil. We compared such patterns considering both reproductive and non-reproductive periods, and how it varies as a function of temperature on a seasonal basis. In Central Brazil, we found a constant, and temperature-independent activity during the night in both reproductive and non-reproductive periods. On the other hand, in Southeastern Brazil, we detected a constant activity during the reproductive period, but in the non-reproductive period G. agilis presented a peak of activity between two and four hours after sunset. Moreover, in this latter we found a relation between temporal activity and temperature during the autumn and spring. These differences in temporal activity between areas, observed during the non-reproductive period, might be associated with the higher seasonal variability in temperature, and lower mean temperatures in the Southeastern site in comparison to the Central one. In Southeastern Brazil, the decrease in temperature during the non-reproductive season possibly forced G. agilis to be active only at certain hours of the night. However, likely due to the reproductive activities (intensive foraging and searching for mates this marsupial showed constant, temperature-independent activity during the night in the reproductive period at both sites.

    The sand lizard (Lacerta agilis, Lacertidae) has a chromosome number of 2n = 38, with 17 pairs of acrocentric chromosomes, one pair of microchromosomes, a large acrocentric Z chromosome, and a micro-W chromosome. To investigate the process of karyotype evolution in L. agilis, we performed chromosome banding and fluorescent in situ hybridization for gene mapping and constructed a cytogenetic map with 86 functional genes. Chromosome banding revealed that the Z chromosome is the fifth largest chromosome. The cytogenetic map revealed homology of the L. agilis Z chromosome with chicken chromosomes 6 and 9. Comparison of the L. agilis cytogenetic map with those of four Toxicofera species with many microchromosomes (Elaphe quadrivirgata, Varanus salvator macromaculatus, Leiolepis reevesii rubritaeniata, and Anolis carolinensis) showed highly conserved linkage homology of L. agilis chromosomes (LAG) 1, 2, 3, 4, 5(Z), 7, 8, 9, and 10 with macrochromosomes and/or macrochromosome segments of the four Toxicofera species. Most of the genes located on the microchromosomes of Toxicofera were localized to LAG6, small acrocentric chromosomes (LAG11-18), and a microchromosome (LAG19) in L. agilis. These results suggest that the L. agilis karyotype resulted from frequent fusions of microchromosomes, which occurred in the ancestral karyotype of Toxicofera and led to the disappearance of microchromosomes and the appearance of many small macrochromosomes.

    2011-10-01

    Full Text Available Gabriele Stein is professor of English linguistics at the University of Heidelberg in Germany and has published widely on lexicography and lexicology. The objective of this book is twofold: to compile a lexical core and to maximise the skills of language students by developing ways of expanding this core. It is intended to function as a teaching aid for teachers of English as well as a self-study book for learners of English as a second language. Lexical knowledge is a crucial part of language acquisition and depends on different external factors such as the age and profession of the learner, his/her goals, expectations and needs in learning a language. Beck et al. (2002 have demonstrated the small extent of the emphasis on the acquisition vocabulary in school curricula.

  11. Effect of Arthrobacter agilis UMCV2 on germination and growth of Pinus devoniana Lindley

    Full Text Available Soil microorganisms are essential for growth, emergence and development in all plants. In our study we decided to evaluate the effect that A. agilis UMCV2 rhizobacteria had on germination and growth of plants of economic-forest interest as P. devoniana to an age of 65 days. Our results show that the UMCV2 bacteria promoted growth of P. devoniana at this early stage of development, further highlighting that despite the short time of interaction between these two, the bacterium was able to increase the rate of germination, increase the size of shoot and generate a proliferation of lateral roots. The data shows a huge potential for using inoculum both in the greenhouse and in open ground and generate a growth promoting species of interest in both agricultural and forest, thereby reducing production periods depending on the crop.

    The modeling of the growth of Nitrobacter agilis cell immobilized in kappa-carrageenan is presented. A detailed description is given of the modeling of internal diffusion and growth of cells in the support matrix in addition to external mass transfer resistance. The model predicts the substrate and biomass profiles in the support as well as the macroscopic oxygen consumption rate of the immobilized biocatalyst in time. The model is tested by experiments with continuously operated airlift loop reactors containing cells immobilized in kappa-carrageenan. The model describes experimental data very well. It is clearly shown that external mass transfer may not be neglected. Furthermore, a sensitivity analysis of the parameters at their values during the experiments revealed that apart from the radius of the spheres and the substrate bulk concentration, the external mass transfer resistance coefficient is the most sensitive parameter for our case.

    Full Text Available Abstract Objective: To analyze the empathy of Edith Stein and the sympathy of Max Scheler for an ethical care of the other. Method: A reflexive, philosophical study anchored in the philosopher Edith Stein's thoughts about empathy for the care of the human person, and likewise of the philosopher Max Scheler on sympathy. It intends to converge the thoughts of the thinkers with the intention of presenting the importance of the care with the person. Results: Stein's empathy leads the human being to perceive the experiences of others and the need for the ethical care of the other; Scheler, in relation to sympathy, brings love as the basis for the ethical care, essential in this relationship with the other. Conclusion: Life and care are become necessary for human relationships, and thus, according to Stein and Scheler's philosophies, each person is invited to perceive the other as a human being.

    Full Text Available Some aspects of the ecology of the skink Mabuya agilis (Raddi, 1823 at the restinga habitat of Grumari, in Rio de Janeiro, Brazil are studied. Most of the lizards were first sighted on the ground, though a few were using perches (mainly cacti up to 30 cm high. Mean body temperature in activity was 33.1 ± 2.4ºC and was significantly correlated to air temperature. There was sexual dimorphism in size (snout-vent length - SVL, with females growing larger than males. Frequency of broken tails was high overall (83% and did not differ between sexes. Females and males are sexually mature at 49 mm and 47 mm SVL, respectively. Brood size averaged 3.2 ± 1.0 (range 1-5 and was positively and significantly related to female SVL (r = 0.65, p = 0.001. Relative clutch mass (RCM of seven gravid females averaged 0.250 ± 0.042, being relatively low compared to those of other congeners. The diet of M. agilis was composed basically of arthropods, with relatively large and soft-bodied arthropods such as spiders, caterpillars and homopterans being the most important prey. The results of our work confirm and expand the knowledge of ecological tendencies previously observed for M. agilis in other areas.

    Plant diseases caused by fungal pathogens such as Botrytis cinerea and the oomycete Phytophthora cinnamomi affect agricultural production worldwide. Control of these pests can be done by the use of fungicides such as captan, which may have deleterious effects on human health. This study demonstrates that the rhizobacterium Arthrobacter agilis UMCV2 produces volatile organic compounds that inhibit the growth of B. cinerea in vitro. A single compound from the volatile blends, namely dimethylhexadecylamine (DMHDA), could inhibit the growth of both B. cinerea and P. cinnamomi when supplied to the growth medium in low concentrations. DMHDA also inhibited the growth of beneficial fungi Trichoderma virens and Trichoderma atroviride but at much higher concentrations. DMHDA-related aminolipids containing 4, 8, 10, 12, and 14 carbons in the alkyl chain were tested for their inhibitory effect on the growth of the pathogens. The results show that the most active compound from those tested was dimethyldodecylamine. This effect correlates with a decrease in the number of membrane lipids present in the mycelium of the pathogen including eicosanoic acid, (Z)-9-hexadecenoic acid, methyl ester, and (Z)-9-octadecenoic acid, methyl ester. Strawberry leaflets treated with DMHDA were not injured by the compound. These data indicate that DMHDA and related compounds, which can be produced by microorganisms may effectively inhibit the proliferation of certain plant pathogens.

  18. UV-deprived coloration reduces success in mate acquisition in male sand lizards (Lacerta agilis.

    Mats Olsson

    Full Text Available Recent work on animal signals has revealed a wide occurrence of UV signals in tetrapods, in particular birds, but also in lizards (and perhaps other Squamate reptiles. Our previous work on the Swedish sand lizard (Lacerta agilis has verified, both in correlative selection analyses in the wild and with laboratory and field experiments, the importance of the green 'badge' on the body sides of adult males for securing mating opportunities, probably mostly through deterring rival males rather than attracting females. The role of UV in communication has, however, never been examined.Here we show that when measured immediately after spring skin shedding, there is also signaling in the UV. By UV-depriving the signal (reflectance with sun block chemicals fixated with permeable, harmless spray dressing, we show that males in the control group (spray dressing only had significantly higher success in mate acquisition than UV-deprived males.These results suggest that at least two colour traits in sand lizards, badge area and UV, contribute to rival deterrence and/or female choice on UV characters, which elevates success in mate acquisition in UV intact male sand lizards.

    Infectious diseases including those caused by parasites can be a major threat to the conservation of endangered species. There is thus a great need for studies describing parasite infections of these species in the wild. Here we present data on parasite diversity in an agile mangabey (Cercocebus agilis) group in Bai Hokou, Dzanga-Sangha Protected Areas (DSPA), Central African Republic. We coproscopically analyzed 140 mangabey fecal samples by concentration techniques (flotation and sedimentation). Agile mangabeys hosted a broad diversity of protistan parasites/commensals, namely amoebas (Entamoeba spp., Iodamoeba buetschlli), a Buxtonella-like ciliate and several parasitic helminths: strongylid and spirurid nematodes, Primasubulura sp., Enterobius sp., and Trichuris sp. Importantly, some of the detected parasite taxa might be of potential zoonotic importance, such as Entamoeba spp. and the helminths Enterobius sp., Trichuris sp., and strongylid nematodes. Detailed morphological examination of ciliate cysts found in mangabeys and comparison with cysts of Balantioides coli from domestic pigs showed no distinguishing structures, although significant differences in cyst size were recorded. Scanning or transmission electron microscopy combined with molecular taxonomy methods are needed to properly identify these ciliates. Further studies using molecular epidemiology are warranted to better understand cross-species transmission and the zoonotic potential of parasites in sympatric non-human primates and humans cohabiting DSPA. © 2018 Wiley Periodicals, Inc.

  20. La femme et sa destinée d'après Edith Stein

    2014-12-01

    Full Text Available Woman's Destiny according Edith Stein The following essay aims to show that Edith Stein's conception of women was a feminist and a traditionalist one. This could be interpreted by some philosophers as a sort of contradiction. Thus the author presents the different arguments detecting such  a conflict between feminism and traditionalism. These arguments are based in fact on the opposition between nature or essence, on the one hand, and freedom, on the other hand. The thesis of the author is that there is not necessarily a conflict between essence and freedom, and that essence is not a fiction but an ontological reality which, interpreted in the way of Edith Stein, makes it possible to conceive sexual difference in a perfect synthesis between the Christian tradition and gender equality.

    Highlights: • Rapid phenol toxicity tests (1 h) were developed based on Chl a fluorescence and the movement parameters of Euglena agilis. • Phenol significantly reduced F v /F m of PS II and rETRmax with EC50 values of 8.94 and 4.67 mM, respectively. • Among the movement parameters tested, velocity was the most sensitive biomarker with an EC50 of 3.17 mM. • The EC50 values for F v /F m , motility, and velocity appear to overlap the environmental permissible levels of phenol. - Abstract: Phenol, a monosubstituted aromatic hydrocarbon with various commercial uses, is a major organic constituent in industrial wastewaters. The ecotoxic action of phenol for aquatic environment is well known. In this study, rapid phenol toxicity tests (1 h) were developed based on chlorophyll a (Chl a) fluorescence and the movement parameters of the freshwater flagellate, Euglena agilis Carter. Phenol significantly reduced the maximum quantum yield (F v /F m ) of photosystem II (PS II) and the maximum photosynthetic electron transport rate (rETR max ) with median effective concentration (EC 50 ) values of 8.94 and 4.67 mM, respectively. Phenol reduced the motility and triggered change in the swimming velocity of the test organism. Among the parameters tested, velocity was the most sensitive biomarker with an EC 50 of 3.17 mM. The EC 50 values for F v /F m , motility, and velocity appear to overlap the permitted levels of phenol. In conclusion, the photosynthesis and movement of E. agilis can be fast and sensitive risk assessment parameters for the evaluation of phenol toxicity in municipal and industrial effluents

    LH determination in the serum significantly assists in diagnosing polycystic ovaries. Values exceeding 22 mIU/ml serum are indicative of a typical picture of polycystic ovaries similar to those found in the Stein-Leventhal syndrome. Lower levels indicate an atypical picture of polycystic ovaries or low-cyst ovary degeneration. FSH level cannot be used for this diagnosis. (author)

    2009-01-01

    The present short note points out a most interesting and quite unexpected connection between the number of distinct knot as a function of their crossing number and exceptional Lie groups and Stein space hierarchies. It is found that the crossing number 7 plays the role of threshold similar to 4 and 5 in E-infinity theory and for the 11 crossing the number of distinct knots is very close to 4α-bar 0 +1=548+1=549, where α-bar 0 =137 is the inverse integer electromagnetic fine structure constant. This is particularly intriguing in view of a similar relation pertinent to the 17 two and three Stein spaces where the total dimension is Σ 1 17 Stein=5α-bar 0 +1=685+1=686, as well as the sum of the eight exceptional Lie symmetry groups Σ i=1 8 |E i |=4α-bar 0 =548. The slight discrepancy of one is explained in both cases by the inclusion of El Naschie's transfinite corrections leading to Σ i=1 8 |E i |=(4)(137+k 0 )=548.328157 and Σ i=1 17 Stein=(5)(137+k 0 )=685.41097, where k o = φ 5 (1 - φ 5 ) and φ=(√(5)-1)/2.

    The helminth fauna of two sympatric congeneric skinks (Mabuya agilis and M. macrorhyncha) from two distinct "restinga" habitats (Praia das Neves and Grussaí) in southeastern Brazil were studied, totalling four data sets (sample sizes ranging from 11 to 28). A total of ten helminth species were associated with the skinks: Raillietiella sp., Paradistomum parvissimum, Pulchrosomoides elegans, Oochoristica ameivae, Hexametra boddaertii, Parapharyngodon sceleratus, Physalopteroides venancioi, Physaloptera sp., an unidentified acuariid nematode and an unidentified centrorhynchid acanthocephalan. Except for Hexametra boddaertii (found only in Grussaí) and Pulchrosomoides elegans (found only in Praia das Neves), all helminth species were present at both localities. Half of the helminth species were present only as larvae and, in most cases, appear to represent paratenic parasitism. Overall prevalences of infection were high for both host species in both localities. Mabuya agilis tended to have richer and more diverse infracommunities than M. macrorhyncha. Some parameters of infection by individual helminth species seem to be related to the ecology of each Mabuya species. The parasite faunas were qualitatively very similar among species and/or localities, but quantitative similarities were more varied, due to differential representativeness of individual helminth species among host populations. The helminth communities of both skink species can be classified as non-interactive, being composed of site-specialists and immature stages of non-lizard parasites.

  9. Closeness and distance in the nurse-patient relation. The relevance of Edith Stein's concept of empathy.

    Science.gov (United States)

    Määttä, Sylvia M

    2006-01-01

    This paper emanates from the concept of empathy as understood by the German philosopher Edith Stein. It begins by highlighting different interpretations of empathy. According to the German philosopher Martin Buber, empathy cannot be achieved as an act of will. In contrast, the psychologist Carl Rogers believes that empathy is identical with dialogue and is the outcome of a cognitive act of active listening. The empathy concept of Edith Stein, philosopher and follower of Edmund Husserl's phenomenology, goes beyond these conflicting views and offers a more complex interpretation, with relevance for both healthcare and nursing education. When studying Stein's three-level model of empathy, a field of tension between perspectives of closeness and distance becomes apparent. The paper concludes by suggesting Stein's model of empathy as a strategy to overcome the tension and meet the demands of empathy.

Stein halló la clave de esa esencia en la idea de originariedad, pero intentó evitar el problema de la empatía estética, sirviéndose de Los ídolos del autoconocimiento de Scheler.

  12. Stein manifolds and holomorphic mappings the homotopy principle in complex analysis

    CERN Document Server

    Forstnerič, Franc

    2017-01-01

    This book, now in a carefully revised second edition, provides an up-to-date account of Oka theory, including the classical Oka-Grauert theory and the wide array of applications to the geometry of Stein manifolds. Oka theory is the field of complex analysis dealing with global problems on Stein manifolds which admit analytic solutions in the absence of topological obstructions. The exposition in the present volume focuses on the notion of an Oka manifold introduced by the author in 2009. It explores connections with elliptic complex geometry initiated by Gromov in 1989, with the Andersén-Lempert theory of holomorphic automorphisms of complex Euclidean spaces and of Stein manifolds with the density property, and with topological methods such as homotopy theory and the Seiberg-Witten theory. Researchers and graduate students interested in the homotopy principle in complex analysis will find this book particularly useful. It is currently the only work that offers a comprehensive introduction to both the Oka t...

    The kingdom Fungi is represented by a large number of organisms, including pathogens that deteriorate the main structural components of wood, such as cellulose, hemicellulose and lignin. The aim of our work was to characterize the antifungal activity in Arthrobacter agilis UMCV2 and diverse amines against wood-decaying fungi. Four fungal organisms (designated as UMTM) were isolated from decaying wood samples obtained from a forest in Cuanajo-Michoacán, México. Two of them showed a clear enzymatic activity of cellulases, xylanases and oxido-reducing enzymes and were identified as Hypocrea (UMTM3 isolate) and Fusarium (UMTM13 isolate). In vitro, the amines showed inhibitory effect against UMTM growth and one of the amines, dimethylhexadecylamine (DMA16), exhibited strong potential as wood preventive treatment, against the attack of decaying fungi.

    The paper focuses on the educational experience produced during the International Workshop, organized by the IUAV University of Venice and dedicated to both the understanding and conservation of the maison Stein-de-Monzie "Les Terrasses", an emblematic work of Le Corbusier's early career period. The villa, located in Garches (Vaucresson), was designed and built between 1926 and 1928, the exact same years when Le Corbusier was elaborating the "Five Points of Architecture" (1927): the building is the first complete application of these principles, while it represents an evolution of the maison Dom-Ino's structural scheme. Nowadays, both the interior spaces and the external surfaces of the maison Stein-de-Monzie show profound changes caused by problematic events leading to the present-day appearance of the building, in many cases misrepresenting the original design goals. The building's integrated instrumental survey (laser scanning, photogrammetry, topography) allowed to document and understand the history of the villa beyond the mere and well known project phase, contributing to the definition of the actual construction characteristics and to ascertain both the material consistency and the state of conservation. The knowledge acquisition process - supported by survey data - constitutes a prerequisite to outline the design of new solutions, which could effectively express the cultural choices connected to the conservation of the Twentieth-Century built heritage.

  20. Females Choose Mates Based on Genetic Relatedness in a Small Dasyurid Marsupial, the Agile Antechinus (Antechinus agilis.

    Directory of Open Access Journals (Sweden)

    Marissa L Parrott

    Full Text Available Females in a variety of taxa mate with more than one male during a single oestrus and exhibit mate preferences for genetically compatible males, but the influence of female mate choice on siring success is not clearly understood. Whether females choose to mate with more than one male or endure forced copulations is also often unknown. Here, we examined the effects of genetic relatedness on female mate choice and siring success in a small semelparous carnivorous marsupial, the agile antechinus (Antechinus agilis, during two consecutive breeding seasons. Experimental trials were conducted in captivity over periods of 72 hours using interconnected enclosures in which female antechinus could choose to access any of four separated males, but males were only able to access females that entered their quarters. Females had access to two genetically similar and two genetically dissimilar males simultaneously and all behavioural interactions were observed and scored from continuous video recordings. Genetic similarity between mates and paternity of young was determined by microsatellite analyses. Some females chose to enter and mate with more than one male during a single oestrus period. Although females investigated all males, they spent significantly more time visiting, and mated more times with, genetically dissimilar males. Males that were genetically dissimilar to the female sired 88% of subsequent offspring. Whilst males mated readily with most females, they rejected the advances of some receptive females, indicating a previously unexpected level of male mate choice. The results show that genetic relatedness between mates has a significant influence on mate choice, breeding and siring success in the agile antechinus.

    The aggregation of parasites among hosts is associated with differential host exposure and susceptibility to parasites, which varies according to host gender, body size, reproductive status and environmental factors. We evaluated the role of these factors on infestation by Eimeria spp. (Eimeriidae) in the agile gracile mouse opossum (Gracilinanus agilis), a semelparous didelphid inhabiting neotropical savannahs. Eimeria spp. abundance and prevalence among G. agilis were associated with the breeding status of individuals and to a lesser extent to climatic season, with both sexes presenting higher Eimeria spp. burdens during late breeding/wet season. On the other hand, male-biased parasitism was restricted to dry/mating season. We suggest that male spatial organization and diet may account for increased parasite burdens within this sex, although future studies should evaluate the role of physiological differences associated with androgen hormones. Finally, a rapid increase in Eimeria spp. loads among females during the late breeding/wet season seems associated with seasonal changes in susceptibility, due to breeding costs related to semelparity, and exposure to infective propagules, while male-die off seems to explain maintenance of higher Eimeria spp. burdens within this sex in the same period.

    On September 5, 2008, the International Rosetta Mission encountered its first formal science target of the mission, asteroid (2867) Steins. We report preliminary results from the U.S. experiments. NASA's contribution to the Rosetta mission consists of an ultraviolet (UV) spectrometer, a microwave spectrometer, a plasma instrument, and a portion of the electronics package for a mass spectrometer. The UV spectrometer (Alice) was used to obtain the first far-ultraviolet (FUV) spectrum of an asteroid. A ten-minute integration, surrounding the time of closest approach, averaging over a variety of geometries, showed very good signal from 850 Angstroms to 2000 Angstroms in the FUV. The microwave instrument (MIRO) obtained a high signal to noise measurement at both observing frequencies, enabling key thermal parameters to be derived. The plasma instrument (IES) obtained a brief measurement of the solar wind, and the Double Focusing Mass Spectrometer (DFMS) of the ROSINA instrument obtained a signal just at closest approach. Laboratory work with analogue materials was begun.

    Various metallurgical investigations were carried out with a view to making technological modifications to the Stein Industrie designed moisture separator reheaters of the 900 MW CP0/CP1 and 1300 MW P4/P'4 plant series. Dismantling and assessment of four reheater bundles from the CP0/CP1 plants revealed tube leaks at the bends and in the straight part of the bundle due chiefly to erosion-corrosion. In addition, thickness losses due to the same phenomenon were observed on the inner walls of the vessels and internal hardware in contact with wet steam. The assessments and inspections carried out in the field on the MSR bundles of the CP0 and CP1 plants confirmed the presence of erosion-corrosion, virtually stabilized to date, and revealed fouling of bends by sequestration of particles in the circuit with presence of some pitting. Fatigue cracking of the last support plate of certain MSRs of the CP0 series was also revealed. Adoption of finned tubes of 18% chrome ferritic stainless steel (Z 2 CT 18) for spare bundles and new MSRs, protection of vessels by austenitic and/or martensitic stainless steel internal hardware, modification of water conditioning in the steam-water circuit, and implementation of some technological modifications should guarantee the longterm resistance of the MSRs [fr

    β-carotene is a commercially important natural pigment and has been widely applied in the medicine, pharmaceutical, food, feed and cosmetic industries. The current study aimed to investigate the usability of molasses for β-carotene production by Arthrobacter agilis A17 (KP318146) and to optimize the production process. Box-Behnken Design of Response Surface Methodology was used to determine the optimum levels and the interactions of three independent variables namely molasses, yeast extract and KH2PO4 at three different levels. β-carotene yield in optimized medium containing 70 g/l molasses, 25 g/l yeast extract and 0.96 g/l KH2PO4, reached up to 100 mg/l, which is approximately 2.5-fold higher than the yield, obtained from control cultivation. A remarkable β-carotene production on inexpensive carbon source was achieved with the use of statistical optimization.

    This commentary reflects the professional life story of a prolific and well-published poet, Howard Stein. An anthropologist by training, Howard's poetry is well known and well respected by family physicians. It is within family medicine that Howard found his professional home, and in his 45-plus-year career he has shared the value of "patient story"; the value of the doctor-patient relationship; and the art of listening deeply to self, colleagues, and patients. This commentary offers a tribute to Howard's professional life and his contributions to family and narrative medicine. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

    Full Text Available The paper focuses on the educational experience produced during the International Workshop, organized by the IUAV University of Venice and dedicated to both the understanding and conservation of the maison Stein-de-Monzie “Les Terrasses”, an emblematic work of Le Corbusier’s early career period. The villa, located in Garches (Vaucresson, was designed and built between 1926 and 1928, the exact same years when Le Corbusier was elaborating the “Five Points of Architecture” (1927: the building is the first complete application of these principles, while it represents an evolution of the maison Dom-Ino’s structural scheme. Nowadays, both the interior spaces and the external surfaces of the maison Stein-de-Monzie show profound changes caused by problematic events leading to the present-day appearance of the building, in many cases misrepresenting the original design goals. The building’s integrated instrumental survey (laser scanning, photogrammetry, topography allowed to document and understand the history of the villa beyond the mere and well known project phase, contributing to the definition of the actual construction characteristics and to ascertain both the material consistency and the state of conservation. The knowledge acquisition process – supported by survey data – constitutes a prerequisite to outline the design of new solutions, which could effectively express the cultural choices connected to the conservation of the Twentieth-Century built heritage.

    Full Text Available This is a retrospective study of 38 cases of infection by Babesia macropus, associated with a syndrome of anaemia and debility in hand-reared or free-ranging juvenile eastern grey kangaroos (Macropus giganteus from coastal New South Wales and south-eastern Queensland between 1995 and 2013. Infection with B. macropus is recorded for the first time in agile wallabies (Macropus agilis from far north Queensland. Animals in which B. macropus infection was considered to be the primary cause of morbidity had marked anaemia, lethargy and neurological signs, and often died. In these cases, parasitised erythrocytes were few or undetectable in peripheral blood samples but were sequestered in large numbers within small vessels of visceral organs, particularly in the kidney and brain, associated with distinctive clusters of extraerythrocytic organisms. Initial identification of this piroplasm in peripheral blood smears and in tissue impression smears and histological sections was confirmed using transmission electron microscopy and molecular analysis. Samples of kidney, brain or blood were tested using PCR and DNA sequencing of the 18S ribosomal RNA and heat shock protein 70 gene using primers specific for piroplasms. The piroplasm detected in these samples had 100% sequence identity in the 18S rRNA region with the recently described Babesia macropus in two eastern grey kangaroos from New South Wales and Queensland, and a high degree of similarity to an unnamed Babesia sp. recently detected in three woylies (Bettongia penicillata ogilbyi in Western Australia.

    2009-01-01

    Full Text Available La presente investigación aborda la pregunta por la especificidad de la mujer en la obra de Edith Stein. La respuesta se centra en tres núcleos significativos importantes, es decir, la pregunta por el fundamento de la especificidad de la mujer, el método adecuado para abordar dicha especificidad con una racionalidad propiamente teológica y el Gemüt en cuanto elemento constitutivo central de dicha especificidad. En efecto, la especificidad de la mujer encuentra su fundamento último en Dios Trino y Uno en cuanto interrelacionada, de modo analógico, con el Espíritu Santo-Amor. Esta interrelación no excluye la especificidad del varón, -ya que este se encuentra, de modo análogo, prefigurado en el Hijo- sino ambas especificidades se incluyen a partir de sus relaciones opuestas. Esto significa que la especificidad de la mujer no destruye la del varón, sino la realza, de modo análogo al Hijo y al Espíritu, teniendo como origen fontal al Padre, principio sin principio, al cual nos asemejamos por medio de nuestro sentir común.This research deals with the question by the specificity of women in the work of Edith Stein. The answer is focused on three important significant cores, i.e. the question by the principle of the specificity of women, the appropriate method to address this specificity with a rationality which is genuinely theological, and the Gemüt in the central constituent part of such specificity. Indeed, the specificity of women finds its ultimate principle in the Triune and One and Only God, such interrelated, as analogical way, with the Holy Spirit-Love. This interrelation does not exclude the specificity of the male, since it is found, similarly, prefigured in the Son - but both specificities are included in its opposite relations. This means that the specificity of women does not destroy that of the male, but highlights, analogically to the Son and the Spirit, with the Father, as fontal source, a beginning without beginning

    Wie gewinnt man im Spiel? Die Analyse von Strategien bei Gesellschaftsspielen ist ein Thema der mathematischen Spieltheorie. Mit ihren Methoden kann man aber nicht nur Spiele wie Schach oder Skat untersuchen, sondern auch verschiedenste Konfliktsituationen, bei denen das Schicksal jedes einzelnen Akteurs nicht nur vom eigenen Verhalten abhängt, sondern auch vom Verhalten der anderen, die ebenso wie er versuchen, ein für sie selbst möglichst positives Ergebnis herauszuschlagen. Die Spieltheorie hat großen Einfluss in den Wirtschaftswissenschaften. Auch in der Psychologie, Soziologie, Biologie und der Militärwissenschaft findet sie Anwendung. In der folgenden Aufgabe geht es aber tatsächlich um ein Spiel, und zwar um ein sehr einfaches, das jeder kennt. Trotzdem ist die Lösung nicht ganz einfach, und wer sie findet, hat schon die eine oder andere grundlegende Idee der Spieltheorie verstanden.

    Full Text Available Teresa de Jesús y Edith Stein son testigos del Amor desbordante, embriagadas en el perfume de la Verdad que las reúne en una búsqueda común. “Cuando venga el Espíritu de la Verdad, él los introducirá en toda la verdad”. Ambas son transformadas, desde la hondura del Espíritu que las habita, en testimonio de la libertad que brota de la Verdad que sale al encuentro; en testimonio de la autenticidad de una vida entregada al Otro/otros; en testimonio de un secreto que las habita, las transforma y las conduce hasta la ofrenda de la propia vida. Porque el testimonio, como afirma Ricoeur, “es también el compromiso de un corazón puro y un compromiso hasta la muerte. Pertenece al destino trágico de la verdad”. Teresa de Jesús ingresa a la vida de la joven filósofa Edith Stein a través de la palabra, del “poema” que relata su propia vida y le descubre un mundo nuevo. Biografía que transforma otra biografía y nos permite hoy reunirlas en la comunidad del testimonio y la mística.

    Directory of Open Access Journals (Sweden)

    2015-10-01

    Full Text Available While approaching modernism as a reaction to a major crisis of modernity, the article asks about reasons of American expatriates to come to Europe and focuses on the birth of Gertrude Stein as a modernist. It argues that Stein conceptualized her personal crisis and search for gender identity as insufficiency of American character and immature culture. Thus she invented her own cultural reasons for moving to Paris. The conceptualization shows in her early writings, Q.E.D., Fernhurst and the first draft of The Making of Americans. While rewriting Q.E.D. into Melanctha and writing the other two stories of Three Lives, Stein started to develop her original style of „portraiture“. She did it independently of any literary esthetic movements and, in „impoverishing“ her vocabulary and employing repetition in a search for abstracted truth, she managed to deautomatize the literary language. Her modernist influence was international, and substantial. Her Czech translation history shows a culturally meaningful delay and deformities. On the other, it also speaks of the newly enlivened modernist spirit in the Czech 1960s.

    Minor bodies in the solar system, such as asteroids and comets, are important sources of information for our knowledge of the solar system formation. Besides other aspects, estimation of a magnetization state of such bodies might prove important in understanding the early aggregation phases of the protoplanetary disk, showing the level of importance of the magnetic forces in the processes involved. Meteorites' magnetization measurements suggest that primitive bodies consist of magnetized material. However, space observations from various flybys give to date diverse results for a global magnetization estimation. The flybys at Braille and Gaspra indicate possible higher magnetization (~ 10-3 Am2/kg), while flybys at Steins and Lutetia show no significant values in the global field change illustrating low global magnetization. Furthermore, the interpretation of remote (during flybys) measurements is very difficult. For correct estimates on the local magnetization one needs (in the best case) multi-point surface measurements. Single point observation has been done by NEAR-Shoemaker on 433 Eros asteroid, revealing no signature in magnetic field that could have origin in asteroid magnetization. Similar results, no magnetization observed, have been provided by evaluation of recent data from ROMAP (Philae lander) and RPC-MAG (Rosetta orbiter) instruments from comet 67P/Churyumov-Gerasimenko. The ROMAP instrument provided measurements from multiple points of the cometary surface as well as data along ballistic path between multiple touchdowns, which support the conclusion of no global magnetization. However, even in case of the in-situ on surface observations the magnetization estimate has a limiting spatial resolution that is dependent on the distance from the surface (~ 50 cm in case of ROMAP). To get information about possible smaller magnetized grains distribution and magnetization strength, the sensor shall be placed as close as possible to the surface. For such

  3. Subspace identification of Hammer stein models using support vector machines

    International Nuclear Information System (INIS)

    Al-Dhaifallah, Mujahed

    2011-01-01

    System identification is the art of finding mathematical tools and algorithms that build an appropriate mathematical model of a system from measured input and output data. Hammerstein model, consisting of a memoryless nonlinearity followed by a dynamic linear element, is often a good trade-off as it can represent some dynamic nonlinear systems very accurately, but is nonetheless quite simple. Moreover, the extensive knowledge about LTI system representations can be applied to the dynamic linear block. On the other hand, finding an effective representation for the nonlinearity is an active area of research. Recently, support vector machines (SVMs) and least squares support vector machines (LS-SVMs) have demonstrated powerful abilities in approximating linear and nonlinear functions. In contrast with other approximation methods, SVMs do not require a-priori structural information. Furthermore, there are well established methods with guaranteed convergence (ordinary least squares, quadratic programming) for fitting LS-SVMs and SVMs. The general objective of this research is to develop new subspace algorithms for Hammerstein systems based on SVM regression.

    2015-01-01

    My aim in this paper is to make use of Edith Stein’s phenomenological analyses of empathy, emotion, and personhood to clarify and critically assess the recent suggestion by Axel Honneth that a basic form of recognition is affective in nature. I will begin by considering Honneth’s own presentation...... of this claim in his discussion of the role of affect in recognitive gestures, as well as in his notion of ‘elementary recognition,’ arguing that while his account contains much of value it also generates problems. On the basis of this analysis, I will try to show that Stein’s account of empathy demarcates...... an elementary form of recognition in a less problematic fashion than does Honneth’s own treatment of this issue. I will then spell out the consequences of this move for the emotional recognition thesis, arguing that Stein’s treatment lends it further credence, before ending with some remarks on the connection...

    In 1935 during a medical meeting behalf in New Orleans was presents a study that included seven cases of women that suffered menstrual dysfunctions, hirsutism and sterility, for laparotomy the description of the ovaries had a pearly white color and it was hypertrophic, the cuneiform resection in both ovaries resulted in correction of the menstrual dysfunction and two of them got pregnancy later on, receiving the name of polycystic ovary syndrome (PCOS). The technological advance facilitates the hormonal analyses demonstrating the hyperandrogenism existence and the mechanism of the anovulation, the PCOS showed to be heterogeneous, reason why it was hindered to define it, this advanced the current trend to question the existence of the PCOS and to accept the convenience, either to change the name or to redefine it, leaving it as a simple syndrome with several phenotypes. The endocrine component includes abnormal secretion of insulin and consequently outlying resistance to this hormone, likewise is hyperandrogenism, dislipoproteinemia and obesity. The hormonal exams are unnecessary for the diagnostic and treatment; it is convenient to demonstrate for sonography the ovarian growth. Other dysfunctions like the congenital suprarenal hyperplasia, hyperprolactinemia and hypotiroidism should be discarded. The treatment should be individualized with relationship to the reason of the consultation and the patients age. It has not been demonstrated that the sensibilitizers use to the insulin avoids long term cardiovascular illness and diabetes. Therefore, the phenotype is heterogeneous with a fickle metabolic component and for it has arisen the restlessness of a better definition of the SPO.

    Full Text Available This text aims to explain why «anthropological monism» is the most adequate perspective in order to understand human reality, and that this ‘monism’ must not be necessarily considered as materialist. I will divide my work in four sections. First, I will explain briefly the Cartesian paradigm and what I consider some of its ontological mistakes. Then, I will try to build a phenomenology of the self with Edith Stein’s anthropology as its base, in order to reunite the two realities separated by Descartes: body and subjectivity. Third, I will talk about the concept of ‘form’ as the inseparable vital principle of living beings and, finally, I will talk about empathy as the phenomenon by which we constitute the idea of ‘I’ and the notion of ‘human being’. This way, monism will be presented as the best option to explain human reality and its activity.

    1990-01-01

    Full Text Available The article contributes to the discussion on source criticism within the research field of Old Norse religion. It examines the common assumption that archaeological sources are always to prefer above written sources from the Middle Ages where the Viking Era is described as such accounts are invariably tendentious and biased. Influenced by theories from the field of social anthropology, however, the article argues for the worth of written sources as a complement to the material ones. As an example, the effort to interpret the inscriptions on the runic stone from Rök are introduced. The article suggests that different kinds of source material offer a spectrum of possibilities out of which none alone, but rather all taken together, can deepen the researcher’s knowledge about the object under study.

    This article refers to coalification of biomass in light of embedding this technique in the regional material flow management. From a process engineering point of view the focus is set on Hydrothermal Carbonization (HTC) and Low Temperature Conversion (LTC). Based on monosaccharides as building blocks of polysaccharides and ligneous biomass, the thermal behavior of glucose, fructose and xylose depending on reaction time and temperature is tracked. Consequently mainly hemicellulosic structures are affected under HTC conditions. However LTC converts both hemicelluloses as well as cellulose. The classification of HTC and LTC products from spent grains in terms of H/C and C/O ratio according to Meunier's coalification diagram ranges HTC coal in the area of lignite and the LTC coal in the area of black coal. This grading in terms of elementary analysis is confirmed by solid state{sup 13}C-NMR spectroscopy. The spectrum of LTC coal from spent grains fashioned at 400 C for duration of 3 h is undistinguishable from the spectrum of black coal. From the chemical point of view these two coals has to be described as identical. However the spectrum of the HTC product made of spent grains fashioned at 250 C for 3 h in a pressurized environment shows similarity to the spectrum of lignite. As engineering usage HTC products are a tool to convert cellulose-based residues in a uniform, high-energy matter for incineration processes. For this in-house waste management of e.g. breweries or sugar refineries could be enhanced. LTC coals are due to their stability eligible to extract CO{sub 2} from the atmosphere via photosynthesis and transfer carbon to the long-term stable geological cycle of matter. Consequential LTC offers an alternative to CCS. As a side effect LTC coals contribute to the elevation of carbon content in soils, which facilitates their water-holding and nutrient-holding capacity.

    The author follows the trace of man and his relationships to mineral resources through the cultural history known: From the first evidence of working and use of rock by man, over copper and iron, then gold and silver, to zinc and lead. The book points out how all sectors of human life received important stimuli from mineral resources. It encompasses a huge section of history, reaching from Mesopotamia as the cradle of culture to the historically relevant events in the central European countries, and describing primitive mining in Anatolia between 8000 and 5000 B.C. as well as the extraction of minerals and their processing in the 20th century. Thus the reader comes to know astonishing facts and details relating to the working conditions for instance of Egyptian and Greek slaves, the mines of Solomon, the first strike in antiquity, the art and social position of smiths since antiquity, and the economic situation of miners and foundry workers. The chapter on medieval mining is restricted to individual aspects of mining in Germany. Mining in modern times is only marginally deals with. The scientific results of the last 20 years are not taken into account. (MOS).

    Full Text Available AIM: The main goal of this study was to investigate the temporal and spatial distribution of Peridinium umbonatum and its relationship with the physical and chemical water variables of the pelagic and littoral zones of Lagoon Bonita, located in Brasília, Distrito Federal; METHODS: Samples were collected at three stations: two in the littoral zone and one in the pelagic zone, every 15 days from April 2005 through March 2006; RESULTS: P. umbonatum was the only member of class Dinophyceae recorded during the entire seasonal cycle, with few exceptions, in both the littoral and pelagic zones of Lagoon Bonita. The highest biovolume (7.5 mm³.L-1 of this alga occurred near shore at the beginning of the rainy season, in November 2005. Smaller values of P. umbonatum biovolume were recorded in May and June 2005, typical dry months; CONCLUSIONS: P. umbonatum and the phytoplankton community as a whole had higher biovolumes in the two littoral zone sites, at the end of the dry season and the beginning of the rains. Both, the temporal and spatial scales were relevant in the presence of P. umbonatum, and the spatial heterogeneity was the dominant factor along the study period. The plant community structure, mainly submersed macrophytes, has affected the P. umbonatum population dynamics that took place at shallow, nutrient-poor conditions, small-size lake, which matches with habitat template described to Lo functional classification established by Reynolds et al. (2002.OBJETIVOS: O principal objetivo deste estudo foi investigar a distribuição temporal e espacial de Peridinium umbonatum e sua relação com as variáveis físicas e químicas da água das zonas pelágica e litorânea da Lagoa Bonita, localizada em Brasília, Distrito Federal; MÉTODOS: As amostras foram coletadas em três estações: duas na zona litorânea e uma na zona pelágica, a cada 15 dias, de abril de 2005 a março de 2006; RESULTADOS: P. umbonatum foi o único membro da classe Dinophyceae registrado durante todo o ciclo sazonal, com poucas exceções, tanto nas zonas litorâneas quanto na zona pelágica da Lagoa Bonita. O maior biovolume dessa alga (7,5 mm³.L-1 ocorreu perto da costa, no início da estação chuvosa, em novembro de 2005. Os menores valores de biovolume P. umbonatum foram registrados em maio e junho de 2005, meses tipicamente secos; CONCLUSÕES: P. umbonatum e a comunidade fitoplanctônica como um todo tiveram os maiores biovolumes nos dois pontos da zona litorânea, no final da estação seca e início das chuvas. Tanto a escala temporal quanto a espacial foram relevantes na ocorrência de P. umbonatum, sendo que a heterogeneidade espacial foi o fator preponderante durante o período de estudo. A estrutura das comunidades de plantas, sobretudo macrófitas submersas, influenciaram na dinâmica populacional de P. umbanatum que ocorreu em um lago raso, pobre em nutrientes e de tamanho pequeno, cujas características coincidem com as características de habitat descritas para o grupo funcional Lo estabelecido por Reynolds et al.

    We study the asymptotic behavior of distribution densities arising in stock price models with stochastic volatility. The main objects of our interest in the present paper are the density of time averages of the squared volatility process and the density of the stock price process in the Stein-Stein and the Heston model. We find explicit formulas for leading terms in asymptotic expansions of these densities and give error estimates. As an application of our results, sharp asymptotic formulas for the implied volatility in the Stein-Stein and the Heston model are obtained.

    Background: Ovarian suppression in the adjuvant treatment of perimenopausal women with breast cancer is an important option. The therapeutic goal can be accomplished by administration of GnRH-analogues, ovarectomy or radiocastration. Patients and methods: We describe the advantages and the therapy related side effects and compare the different treatment modalities with each other. Results: Because of its reversibility and patients' compliance GnRH-analogues seem to be advantageous especially in younger premenopausal women. When longer term side effects of artificially induced menopause are less important, therapeutic alternatives such as radiocastration or ovarectomy are effective without obvious superiority between these options. Conclusion: Even in the background of the increasing use of GnRH-analogues radiocastration remains still a therapeutic alternative because of its cost-effectiveness and feasibility. This accounts especially for peri- or premenopausal women above the age of 45. (orig.) [German] Hintergrund: Bei praemenopausalen Patienten mit rezeptorpositiven Mammakarzinomen stellt die ovarielle Suppression einen wichtigen Schritt in der adjuvanten Therapie dar. Neben den GnRH-Analoga kommen hierfuer die Ovarektomie oder die Radiomenolyse infrage. Patienten und Methode: Die vorliegende Arbeit stellt die Vorteile der einzelnen Therapieoptionen den therapiebedingten Nebenwirkungen gegenueber und vergleicht die Methoden untereinander. Ergebnisse: Wegen der Reversibilitaet und der Patientenakzeptanz sollten GnRH-Analoga besonders bei juengeren praemenopausalen Patientinnen angewendet werden. In der Differentialtherapie von Patientinnen, bei denen die Langzeitnebenwirkungen einer iatrogen induzierten Menopause weniger zu befuerchten sind, kommen auch die anderen Verfahren in Betracht. Hierbei stehen Radiomenolyse und Ovarektomie gleichwertig nebeneinander. Schlussfolgerung: Die differentialtherapeutische Entscheidung zu einer der Methoden sollte individualisiert werden. Auch bei zunehmendem Gebrauch der GnRH-Anlage stellt die Radiomenolyse eine zeitgemaesse und kostenguenstige Therapiemodalitaet besonders bei peri- oder praemenopausalen Patientinnen ueber 45 Jahre dar.

    Full Text Available The article focuses on the experiences of Gertrude Stein in France during World War II that is portrayed in her book "Wars I Have Seen." The book depicts a picture of her and her partner Alice B. Toklas as well as an emphasis on media technologies. The book reveals that Stein has been preoccupied during the war with disconnected telephones and addictive radio. It also discusses the impact of acoustic communication technologies on war writing.

We provide an applicable theorem to check the conditions for a general class of Markovian stochastic volatility models. As an example we will also provide a detailed analysis of the Stein and Stein and Heston stochastic volatility models.

    2002-05-01

    We have studied the terrestrial reptile fauna of the Abrolhos Archipelago (a group of five islands located ca. 70 km off the southern coast of the State of Bahia, Brazil) and analyze here some of its ecological aspects such as diet, thermal ecology, activity, and some reproductive parameters. Three lizards comprise the archipelago's terrestrial reptile fauna: Tropidurus torquatus (Tropiduridae), Mabuya agilis (Scincidae), and Hemidactylus mabouia (Gekkonidae). The first two are diurnal and the latter is crepuscular/nocturnal (initiating activity at ca. 17:30). The activity period of T. torquatus extended from 5:30 to 18:30 h. Mean field body temperatures of active T. torquatus, M. agilis, and H. mabouia were, respectively, 34.0 +/- 3.7 degrees C (range 23.8-38.0 degrees C; N = 75), 34.5 +/- 2.2 degrees C (range 30.8-37.0 degrees C; N = 6), and 26.3 +/- 1.1 degrees C (range 24.8-28.0 degrees C; N = 8). The predominant prey items in the diet of T. torquatus were ants, coleopterans, and hemipterans. In the diet of M. agilis, coleopterans were the most frequent prey items. For H. mabouia, the most important dietary items were orthopterans. Clutch size of T. torquatus averaged 4.1 +/- 1.1 (range 2-6; N = 15) and was significantly related to female size (R2 = 0.618; p = 0.001; N = 15). Clutch size for H. mabouia was fixed (two) and mean litter size of the viviparous M. agilis was 3.3 +/- 0.6 (range 3-4; N = 3). Tropidurus torquatus and H. mabouia deposit their eggs under rocks in the study area, with the former burying them but not the latter; in both species, more than one female often oviposit under the same rock.

    Full Text Available The Hokou gecko (Gekko hokouensis: Gekkonidae, Gekkota, Squamata has the chromosome number 2n = 38, with no microchromosomes. For molecular cytogenetic characterization of the gekkotan karyotype, we constructed a cytogenetic map for G. hokouensis, which retains the ancestral karyotype of Gekkota, with 86 functional genes, and compared it with cytogenetic maps for four Toxicofera species that have many microchromosomes (Elaphe quadrivirgata, Varanus salvator macromaculatus, Leiolepis reevesii rubritaeniata, and Anolis carolinensis and that for a lacertid species (Lacerta agilis with only one pair of autosomal microchromosomes. Ten pairs of G. hokouensis chromosomes [GHO1, 2, 3, Z(4, 6, 7, 8, 13, 14, and 15] showed highly conserved linkage homology with macrochromosomes and/or macrochromosome arms of the four Toxicofera species and corresponded to eight L. agilis macrochromosomes (LAG. However, GHO5, GHO9, GHO10, GHO11, and LAG6 were composed of chromosome segments that have a homology with Toxicofera microchromosomes, and no homology was found in the chromosomes between G. hokouensis and L. agilis. These results suggest that repeated fusions of microchromosomes may have occurred independently in each lineage of Gekkota and Lacertidae, leading to the disappearance of microchromosomes and appearance of small-sized macrochromosomes.

  4. Estimation of a multivariate mean under model selection uncertainty

    Georges Nguefack-Tsague

    2014-05-01

    Full Text Available Model selection uncertainty would occur if we selected a model based on one data set and subsequently applied it for statistical inferences, because the "correct" model would not be selected with certainty.  When the selection and inference are based on the same dataset, some additional problems arise due to the correlation of the two stages (selection and inference. In this paper model selection uncertainty is considered and model averaging is proposed. The proposal is related to the theory of James and Stein of estimating more than three parameters from independent normal observations. We suggest that a model averaging scheme taking into account the selection procedure could be more appropriate than model selection alone. Some properties of this model averaging estimator are investigated; in particular we show using Stein's results that it is a minimax estimator and can outperform Stein-type estimators.

    Gravitational deflection of starlight around the Sun during the 1919 total solar eclipse provided measurements that confirmed Einstein's general theory of relativity. We have used the Hubble Space Telescope to measure the analogous process of astrometric microlensing caused by a nearby star, the white dwarf Stein 2051 B. As Stein 2051 B passed closely in front of a background star, the background star's position was deflected. Measurement of this deflection at multiple epochs allowed us to determine the mass of Stein 2051 B-the sixth-nearest white dwarf to the Sun-as 0.675 ± 0.051 solar masses. This mass determination provides confirmation of the physics of degenerate matter and lends support to white dwarf evolutionary theory.

    Patrascu JM¹,

    2016-12-01

    Full Text Available OBJECTIVES AND BACKGROUND The purpose of this study is to provide a simple, cost-effective, reproducible technology that is able to regenerate durable hyaline cartilage. Traumas and sports along with different diseases such as obesity or gradual degeneration over time of the joint surface determine cartilage defects resulting in pain and dysfunctionality. MATERIALS AND METHODS Since 2011 a number of 183 pacients were treated using Agili-C, out of which 40 pacients were operated in the IInd Clinic of Orthopaedics of the Timișoara Emergency County Hospital. The implant is a biphasic, porous, resorbable tissue regeneration scaffold used in the treatment of osteochondral defects. The surgical procedure is performed through minimal arthrotomy, with a good exposure of the cartilage defect. The implant is inserted so that the articular surface of the implant is parallel with the surrounding healthy cartilage. When in place, it facilitates vascularization thus allowing tissue formation to commence from the periphery towards the center of the defect. RESULTS Until now, results are promising, showing obvious improvements in pain and function in both degenerative and post-traumatic joint lesions in the knee, ankle and first MP joint. CONCLUSIONS Agili-C is a cell free, single stage, off the shelf implant that will hopefully meet market demands and become a reliable procedure in joint repair surgery in the future.

  10. Multi-Frequency Polarimetric SAR Classification Based on Riemannian Manifold and Simultaneous Sparse Representation

    Directory of Open Access Journals (Sweden)

    Fan Yang

    2015-07-01

    Full Text Available Normally, polarimetric SAR classification is a high-dimensional nonlinear mapping problem. In the realm of pattern recognition, sparse representation is a very efficacious and powerful approach. As classical descriptors of polarimetric SAR, covariance and coherency matrices are Hermitian semidefinite and form a Riemannian manifold. Conventional Euclidean metrics are not suitable for a Riemannian manifold, and hence, normal sparse representation classification cannot be applied to polarimetric SAR directly. This paper proposes a new land cover classification approach for polarimetric SAR. There are two principal novelties in this paper. First, a Stein kernel on a Riemannian manifold instead of Euclidean metrics, combined with sparse representation, is employed for polarimetric SAR land cover classification. This approach is named Stein-sparse representation-based classification (SRC. Second, using simultaneous sparse representation and reasonable assumptions of the correlation of representation among different frequency bands, Stein-SRC is generalized to simultaneous Stein-SRC for multi-frequency polarimetric SAR classification. These classifiers are assessed using polarimetric SAR images from the Airborne Synthetic Aperture Radar (AIRSAR sensor of the Jet Propulsion Laboratory (JPL and the Electromagnetics Institute Synthetic Aperture Radar (EMISAR sensor of the Technical University of Denmark (DTU. Experiments on single-band and multi-band data both show that these approaches acquire more accurate classification results in comparison to many conventional and advanced classifiers.

    Our results show that Sorghum bicolor is able to recognize bacteria through its volatile compounds and differentially respond to beneficial or pathogens via eliciting nutritional or defense adaptive traits. Plants establish beneficial, harmful, or neutral relationships with bacteria. Plant growth promoting rhizobacteria (PGPR) emit volatile compounds (VCs), which may act as molecular cues influencing plant development, nutrition, and/or defense. In this study, we compared the effects of VCs produced by bacteria with different lifestyles, including Arthrobacter agilis UMCV2, Bacillus methylotrophicus M4-96, Sinorhizobium meliloti 1021, the plant pathogen Pseudomonas aeruginosa PAO1, and the commensal rhizobacterium Bacillus sp. L2-64, on S. bicolor. We show that VCs from all tested bacteria, except Bacillus sp. L2-64, increased biomass and chlorophyll content, and improved root architecture, but notheworthy A. agilis induced the release of attractant molecules, whereas P. aeruginosa activated the exudation of growth inhibitory compounds by roots. An analysis of the expression of iron-transporters SbIRT1, SbIRT2, SbYS1, and SbYS2 and genes related to plant defense pathways COI1 and PR-1 indicated that beneficial, pathogenic, and commensal bacteria could up-regulate iron transporters, whereas only beneficial and pathogenic species could induce a defense response. These results show how S. bicolor could recognize bacteria through their volatiles profiles and highlight that PGPR or pathogens can elicit nutritional or defensive traits in plants.

Three lizards comprise the archipelago's terrestrial reptile fauna: Tropidurus torquatus (Tropiduridae, Mabuya agilis (Scincidae, and Hemidactylus mabouia (Gekkonidae. The first two are diurnal and the latter is crepuscular/nocturnal (initiating activity at ca. 17:30. The activity period of T. torquatus extended from 5:30 to 18:30 h. Mean field body temperatures of active T. torquatus, M. agilis, and H. mabouia were, respectively, 34.0 ± 3.7ºC (range 23.8-38.0ºC; N = 75, 34.5 ± 2.2ºC (range 30.8-37.0ºC; N = 6, and 26.3 ± 1.1ºC (range 24.8-28.0ºC; N = 8. The predominant prey items in the diet of T. torquatus were ants, coleopterans, and hemipterans. In the diet of M. agilis, coleopterans were the most frequent prey items. For H. mabouia, the most important dietary items were orthopterans. Clutch size of T. torquatus averaged 4.1 ± 1.1 (range 2-6; N = 15 and was significantly related to female size (R² = 0.618; p = 0.001; N = 15.

  12. Gertrude Stein’s Tender Buttons (1911)

    DEFF Research Database (Denmark)

    Balle, Søren Hattesen

    Gertrude Stein’s book of prose poems Tender Buttons has been characterized as a modernist literary work by most of its critics. As a distinctive feature of its modernist poetics critics in particular emphasize Stein’s denial of representation through verbal abstraction and autotelism. This paper......, however, intends to read Tender Buttons somewhat differently by suggesting that the poems may be viewed as an example of a displaced Rabbinic hermeneutics in the sense given the term by Susan Handelman. Inasmuch as Stein refuses to name the many objects properly that the titles of the poems introduce...... and instead – to employ her own term – “abuses” their names by way of wordplay, punning, syntactical ambiguity, and semantic disruption, she impersonates a secular Reb Stein, who stays faithful to the Scripture by sacred contempt of representation and obedience to (the play of) the letter.

    ABSTRACT: This article examines the use of pictorial illustrations in African language dictionar-ies, with particular reference to items generally included in dictionaries based on Stein's (1991 categories. It argues for the need to include more illustrations of cultural items specific to a par-ticular community and language group in dictionaries. A corpus analytic survey is done to deter-mine if African language dictionaries employ pictorial illustrations and, if so, which items are illus-trated. The results of this survey indicate that only a few African language dictionaries employ pictorial illustrations, even those that do correspond to Stein's categories. Of the dictionaries exam-ined, only one uses illustrations in the form of full-colour photographs, namely of different kinds of cattle, a very important cultural item within that specific community.

While traditional techniques in open 4-manifold smoothing theory give no control of minimal genera, we make progress by using the adjunction inequality for Stein surfaces. Smoothings can be constructed with much more control of these genus functions than the compact setting seems to allow. As an application, we expand the range of 4-manifolds known to have exotic smoothings (up to ...

  7. Have recent earthquakes exposed flaws in or misunderstandings of probabilistic seismic hazard analysis?

    Science.gov (United States)

    Hanks, Thomas C.; Beroza, Gregory C.; Toda, Shinji

    2012-01-01

    In a recent Opinion piece in these pages, Stein et al. (2011) offer a remarkable indictment of the methods, models, and results of probabilistic seismic hazard analysis (PSHA). The principal object of their concern is the PSHA map for Japan released by the Japan Headquarters for Earthquake Research Promotion (HERP), which is reproduced by Stein et al. (2011) as their Figure 1 and also here as our Figure 1. It shows the probability of exceedance (also referred to as the “hazard”) of the Japan Meteorological Agency (JMA) intensity 6–lower (JMA 6–) in Japan for the 30-year period beginning in January 2010. JMA 6– is an earthquake-damage intensity measure that is associated with fairly strong ground motion that can be damaging to well-built structures and is potentially destructive to poor construction (HERP, 2005, appendix 5). Reiterating Geller (2011, p. 408), Stein et al. (2011, p. 623) have this to say about Figure 1: The regions assessed as most dangerous are the zones of three hypothetical “scenario earthquakes” (Tokai, Tonankai, and Nankai; see map). However, since 1979, earthquakes that caused 10 or more fatalities in Japan actually occurred in places assigned a relatively low probability. This discrepancy—the latest in a string of negative results for the characteristic model and its cousin the seismic-gap model—strongly suggest that the hazard map and the methods used to produce it are flawed and should be discarded. Given the central role that PSHA now plays in seismic risk analysis, performance-based engineering, and design-basis ground motions, discarding PSHA would have important consequences. We are not persuaded by the arguments of Geller (2011) and Stein et al. (2011) for doing so because important misunderstandings about PSHA seem to have conditioned them. In the quotation above, for example, they have confused important differences between earthquake-occurrence observations and ground-motion hazard calculations.

    Two new species, Oswaldocruzia lisnykiensis sp. n. and Oswaldocruzia lacertica sp. n., are described from Anguis fragilis L. (Reptilia: Anquidae) and Lacerta agilis L. (Reptilia: Lacertidae) respectively. Both species belong to the Palaearctic group of species which have spicules divided in three main branches (blade, fork and shoe) with fork division above its distal third. The new species differs from all previously known Palaearctic species by several morphological characters: type of caudal bursa (type III in O. lisnykiensis and type I in O. lacertica), shape of spicules (blade distally divided into four tips and specific shape of shoe) and synlophe structure (narrow cervical alae consist of three crests in both species). Illustrated descriptions of O. lisnykiensis and O. lacertica based on 63 and 38 specimens respectively are presented. Host specificity and geographical distribution of the species are discussed. O. dispar is considered as a species inquirenda.

    Full Text Available The identification of previously captured individuals is essential for a wide variety of ecological and behavioural studies. A lot of different methods are used for marking lizards, however they have many drawbacks. In presented study we used heat-branding method, using pen-like medical cautery units, previously employed to successfully mark other lizard species and snakes. The technique is permanent, readable and harmless for lizards, as well quick and easy. In 2009 we marked 111 individuals of sand lizard, Lacerta agilis. Next year we caught 88 lizards, 17 of them were re-captured. Among these re-captured lizards, five were caught after 26.8 (± 16.3 days (means in the same year and 12 after 308.8 (± 64.3 days (means in the next year. Recaptured individuals were still unambiguously recognisable.

    To determine whether the Lyme disease spirochete Borrelia lusitaniae is associated with lizards, we compared the prevalence and genospecies of spirochetes present in rodent- and lizard-associated ticks at a site where this spirochete frequently infects questing ticks. Whereas questing nymphal Ixodes ricinus ticks were infected mainly by Borrelia afzelii, one-half of the infected adult ticks harbored B. lusitaniae at our study site. Lyme disease spirochetes were more prevalent in sand lizards (Lacerta agilis) and common wall lizards (Podarcis muralis) than in small rodents. Although subadult ticks feeding on rodents acquired mainly B. afzelii, subadult ticks feeding on lizards became infected by B. lusitaniae. Genetic analysis confirmed that the spirochetes isolated from ticks feeding on lizards are members of the B. lusitaniae genospecies and resemble type strain PotiB2. At our central European study site, lizards, which were previously considered zooprophylactic for the agent of Lyme disease, appear to perpetuate B. lusitaniae. PMID:16820453

    Scanning electron microscopy (SEM) methods were used for the first time to elucidate the external morphology of the European species of the genus Eulachnus (Hemiptera: Aphididae: Lachninae), a representative genus of the conifer-feeding aphids tribe Eulachnini. We examined and compared the external morphology of apterous and alate viviparous females from the parthenogenetic generation as well as oviparous females and alate males belonging to the sexual generation. FE-SEM images based on HMDS and cryo-SEM preparation techniques revealed better image quality than the CPD technique in regard to surface tension and morphological signs of cell deteriorations (i.e., existence of depressions, drying artifacts and membrane blebs). Three morphologically different species groups "agilis", "brevipilosus" and "cembrae" were proposed due to the differences in head, antennae, legs and dorsal chaetotaxy as well as dorsal sclerotization. The most characteristic features and differences of representatives of these groups are presented and discussed. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Adult dietary regimes in insects may affect egg production, fecundity and ultimately fitness. This is especially relevant in parasitoid wasps where many species serve as important biological control agents of agricultural pests. Here, we tested the effect of honey and sugar diets on daily fecundity schedules, lifetime reproductive success and longevity in four species of parasitoid wasps when reared on their respective hosts. The parasitoid species were selected based on dichotomies in host usage strategies and reproductive traits. Gelis agilis and G. areator are idiobiont ecto-parasitoids that develop in non-growing hosts, feed on protein-rich host fluids to maximize reproduction as adults and produce small numbers of large eggs. Meteorus pulchricornis and Microplitis mediator are koinobiont endoparasitoids that develop inside the bodies of growing hosts, do not host-feed, and produce greater numbers of small eggs. Parasitoids were reared on diets of either pure honey (containing trace amounts of proteins), heated honey (with denatured proteins) and a honey-mimic containing sugars only. We hypothesized that the benefits of proteins in honey would enhance reproduction in the ectoparasitoids due to their high metabolic investment per egg, but not in the koinobionts. Pure honey diet resulted in higher lifetime fecundity in G. agilis compared with the honey-mimic, whereas in both koinobionts, reproductive success did not vary significantly with diet. Longevity was less affected by diet in all of the parasitoids, although there were variable trade-offs between host access and longevity in the four species. We argue that there are both trait-based and association-specific effects of supplementary nutrients in honey on reproductive investment and success in parasitoid wasps.

    The historically-famous Lotus Fortress site, a deep 1.5–3.0-meter-high, 200-meter-long horizonal notch high up in near-vertical sandstone cliffs comprising the Cretaceous Jiaguan Formation, has been known since the 13th Century as an impregnable defensive position. The site is also extraordinary for having multiple tetrapod track-bearing levels, of which the lower two form the floor of part of the notch, and yield very well preserved asseamblages of ornithopod, bird (avian theropod) and pterosaur tracks. Trackway counts indicate that ornithopods dominate (69%) accounting for at least 165 trackmakers, followed by bird (18%), sauropod (10%), and pterosaur (3%). Previous studies designated Lotus Fortress as the type locality of Caririchnium lotus and Wupus agilis both of which are recognized here as valid ichnotaxa. On the basis of multiple parallel trackways both are interpreted as representing the trackways of gregarious species. C. lotus is redescribed here in detail and interpreted to indicate two age cohorts representing subadults that were sometimes bipedal and larger quadrupedal adults. Two other previously described dinosaurian ichnospecies, are here reinterpreted as underprints and considered nomina dubia. Like a growing number of significant tetrapod tracksites in China the Lotus Fortress site reveals new information about the composition of tetrapod faunas from formations in which the skeletal record is sparse. In particular, the site shows the relatively high abundance of Caririchium in a region where saurischian ichnofaunas are often dominant. It is also the only site known to have yielded Wupus agilis. In combination with information from other tracksites from the Jiaguan formation and other Cretaceous formations in the region, the track record is proving increasingly impotant as a major source of information on the vertebrate faunas of the region.

  14. Encounter of a different kind: Rosetta observes asteroid at close quarters

    Science.gov (United States)

    2008-09-01

    ESA's comet chaser, Rosetta, last night flew by a small body in the main asteroid belt, asteroid Steins, collecting a wealth of information about this rare type of minor Solar System body. At 20:58 CEST (18:58 UT) last night, ESA's Rosetta probe approached asteroid 2867 Steins, coming to within a distance of only 800 km from it. Steins is Rosetta's first nominal scientific target in its 11½ year mission to ultimately explore the nucleus of Comet 67P/Churyumov-Gerasimenko. The success of this 'close' encounter was confirmed at 22:14 CEST, when ESA's ground control team at the European Space Operations Centre (ESOC) in Darmstadt, Germany, received initial telemetry from the spacecraft. During the flyby operations, Rosetta was out of reach as regards communication links because its antenna had to be turned away from Earth. At a distance of about 2.41 AU (360 million kilometres) from our planet, the radio signal from the probe took 20 minutes to reach the ground. Steins is a small asteroid of irregular shape with a diameter of only 4.6 km. It belongs to the rare class of E-type asteroids, which had not been directly observed by an interplanetary spacecraft before. Such asteroids are quite small in size and orbit and are mostly found in the inner part of the main asteroid belt located between Mars and Jupiter. They probably originate from the mantle of larger asteroids destroyed in the early history of the Solar System, and are thought to be composed mainly of silicate minerals with little or no iron content. The data collected by Rosetta last night and which will be analysed over the coming days and weeks will finally unveil the true nature of Steins. Through the study of minor bodies such as asteroids, Rosetta is opening up a new window onto the early history of our Solar System. It will give us a better understanding of the origins and evolution of the planets, and also a key to better interpreting asteroid data collected from the ground. Under Rosetta's scope This

    !n this paper we developed a wavelet neural network. (WNN) algorithm for Electroencephalogram (EEG) artifact removal without electrooculographic (EOG) recordings. The algorithm combines the universal approximation characteristics of neural network and the time/frequency property of wavelet. We. compared the WNN algorithm with .the ICA technique ,and a wavelet thresholding method, which was realized by using the Stein's unbiased risk estimate (SURE) with an adaptive gradient-based optimal threshold. Experimental results on a driving test data set show that WNN can remove EEG artifacts effectively without diminishing useful EEG information even for very noisy data.

    Full Text Available One may argue that it all started with Gertrude Stein and her focus on the constraints imposed by language on perception and the subsequent grammar of infinite repetitivity and minute variation that informs her poetic texts. This notion of a subject permanently and irredeemably caught in the very “structure” of his expressive modes opens up a multiplicity of debates centred around the attempts at assessing and gaining control over these restrictions.One of them lies in the impulse to free poe...

    Between 1987 and 1989 10,55 million ecus were given by the European Commission's Demonstration Programme for the construction of the Emile Huchet power station using circulating fluidized bed combustion technology. The power station was constructed jointly by Charbonnages de France, COREAL, Stein Industrie and Lurgi. An important feature was its ability to burn coal preparation wastes cleanly. Despite burning poor quality fuel its emissions are well below the maximum standards. Other stations of this type are now planned in France.

  13. Analytic formulas for the topological degree of non-smooth mappings: The odd-dimensional case

    OpenAIRE

    2012-01-01

    The notion of topological degree is studied for mappings from the boundary of a relatively compact strictly pseudo-convex domain in a Stein manifold into a manifold in terms of index theory of Toeplitz operators on the Hardy space. The index formalism of non-commutative geometry is used to derive analytic integral formulas for the index of a Toeplitz operator with H\\"older continuous symbol. The index formula gives an analytic formula for the degree of a H\\"older continuous mapping from the b...

    1979-06-01

    Evidence for a general social deviancy subcultural factor was found using the Kulik, Sarbin, and Stein (1971) slang test on drugs, gangs, law enforcement, and general words. The slang scores of 68 confirmed opiate addicts exceeded those of normals and young delinquents reported by Kulik, et al. (1971), including delinquents who were recidivists. Addicts knew more drug and alcohol slang than slang in the three other categories. It was recommended that more attempts should be made to subdivide measures of social deviancy by means of slang as there is some evidence of possible further differentiation of subcultural types by means of slang.

    Some practical approaches to the difficult problems in calibrating and implementing differential-pressure measurements are discussed. The data presented were gathered several years ago in separate investigations. An attempt is made to compare the results of these investigations to the common mode concept as described by Peter K. Stein in his publication, The Measurement of Differential Quantities - Problems and Approaches. Although one of these investigations involed a 10,000- to 20,000-psi reference-pressure gas measured at an ambient temperature and the other a classic /sup Δ/P flow measurement of cryogenic temperature, the problems encountered were the same

  6. Numerical investigation on exterior conformal mappings with application to airfoils

    International Nuclear Information System (INIS)

    Mohamad Rashidi Md Razali; Hu Laey Nee

    2000-01-01

    A numerical method is described in computing a conformal map from an exterior region onto the exterior of the unit disk. The numerical method is based on a boundary integral equation which is similar to the Kerzman-Stein integral equation for interior mapping. Some examples show that numerical results of high accuracy can be obtained provided that the boundaries are smooth. This numerical method has been applied to the mapping airfoils. However, due to the fact that the parametric representation of an air foil is not known, a cubic spline interpolation method has been used. Some numerical examples with satisfying results have been obtained for the symmetrical and cambered airfoils. (Author)

    We study the modified Bessel P-integral, whose properties are similar to those of the Bessel potential, and the modified Bessel P-derivative. These operators are inverse to each other. We prove analogues of the embedding theorems of Hardy, Littlewood, Stein, Zygmund and Lizorkin concerning the images of L p (R) under the action of Bessel potentials. We give applications of the Bessel integral and derivative to the integrability of the P-adic Fourier transform and to approximation theory (an embedding theorem of Ul'yanov type)

    Full Text Available Temporary ponds represent special environments that are inhabited by organisms adapted to changing environmental conditions. Ciliates are able to survive complete loss of water in these transient habitats through cyst formation. However, ciliates from the Neotropical region in general have been poorly studied with modern techniques. The main goal of this study is to describe the ciliates in dried sediments of a temporary pond from Buenos Aires Province, Argentina, through sampling efforts that were performed 2003-2005. Soil samples were obtained during drought phases and re wetted in laboratory to establish raw and enriched cultures. Ciliates were then studied both in vivo and after impregnation with protargol. In this study, we present 4 new records for Argentina (Gonostomum affine (Stein, 1859 Sterki, 1878, Stylonychia bifaria (Stokes, 1887 Berger, 1999, Pleurotricha lanceolata (Ehrenberg, 1835 Stein, 1859, Meseres corlissi Petz and Foissner, 1992, 1 for South America (Blepharisma americanum (Suzuki, 1954 Hirshfield, Isquith and Bhandary, 1965, and 2 for the Neotropical Realm (Gonostomum strenuum (Engelmann, 1862 Sterki, 1878, Stylonychia lemnae Ammermann and Schlegel, 1983.Los cuerpos de agua temporarios son ambientes particulares que se encuentran habitados por organismos adaptados a condiciones fluctuantes.

O setor 1, que corresponde ao Saco da Ribeira e Codo, tem sedimento composto por areia e lodo, relativamente rico em materia orgânica onde algumas especies, como Spiochaetopterus costarum e Scoloplos treadwelli, alcançam densidades elevadas. O setor 2, que corresponde a Ribeira e Flamengo e cujo fundo e constituído por areia e lodo, distingue-se pela presença marcante de Owenia fusiforms nos locais ricos em cascalho. O setor 3, que abrange o Perequé-Mirim e Santa Rita, apresenta Armandia agilis como a especie dominante, onde o tipo de substrato é areia muito fina. O setor 4, que corresponde à região do infralitoral da Praia da Enseada, com sedimento muito fino, pobre em matéria orgânica tem como especie dominante Armandia Agilis. O setor 5, abrangendo toda a Enseada das Palmas, com as regiões das praias Grande e do Presídio, apresenta semelhanças físicas com a enseada do continente e nele, também, Armandia Agilis foi a espécie dominante.

Methods A total of 300, 1-d-old healthy broiler chickens were randomly divided into five treatment groups: i basal diet (control, ii basal diet+0.25% yeast (Saccharomyces cerevisiae (YC, iii basal diet+0.25% yeast with bacteriocin (BA, iv basal diet+Lactobacillus cultures (LAB, and v basal diet +0.25% yeast with bacteriocin+Lactobacillus cultures (BA+LAB. Growth performance, cecal microbiota, cecal fermentation products, and blood biochemistry parameters were determined when chickens were 21 and 35 d old. Results The supplementation of YC, BA, and BA+LAB resulted in a significantly better feed conversion rate (FCR than that of the control group during 1 to 21 d (p<0.05. The LAB supplementation had a significant effect on the presence of Lactobacillus in the ceca at 35 d. None of the supplements had an effect on relative numbers of L. agilis and L. reuter at 21 d, but the BA supplementation resulted in the decrease of both Lactobacillus strains at 35 d. The BA+LAB supplementation resulted in higher short chain fatty acid (SCFA in the ceca, but LAB supplementation significantly decreased the SCFA at 35 d (p<0.05. All treatments tended to decrease ammonia concentration in the ceca at 21 d, especially in the LAB treatment group. The BA supplementation alone decreased the triacylglycerol (TG concentration significantly at 21 d (p<0.05, but the synergistic effect of BA and LAB supplementation was required to reduce the TG concentration at 35 d. The YC supplementation tended to increase the plasma cholesterol at 21 d and 35 d. However, the BA supplementation significantly decreased the cholesterol and low density lipoprotein cholesterol level at 35 d. In conclusion, the BA

    Most of the western United States is experiencing the effects of rapid and directional climate change (Garfin et al. 2013). These effects, along with forecasts of profound changes in the future, provide strong motivation for resource managers to learn about and prepare for future changes. Climate adaptation plans are based on an understanding of historic climate variation and their effects on ecosystems and on forecasts of future climate trends. Frameworks for climate adaptation thus universally identify the importance of a summary of historical, current, and projected climates (Glick, Stein, and Edelson 2011; Cross et al. 2013; Stein et al. 2014). Trends in physical climate variables are usually the basis for evaluating the exposure component in vulnerability assessments. Thus, this chapter focuses on step 2 of the Climate-Smart Conservation framework (chap. 2): vulnerability assessment. We present analyses of historical and current observations of temperature, precipitation, and other key climate measurements to provide context and a baseline for interpreting the ecological impacts of projected climate changes.

In cases of postnatal AGS values were much lower, but they were clearly in excess of those recordable from Stein-Leventhal syndrome. Plasma borne testosterone in cases of hirsutism came very close to testosterone levels established in the context of Stein-Leventhal syndrome. Testosterone levels dropped with significance, following AGS treatment, using cortisol derivatives, and following wedge-shaped ovariectomy. Sexual hormone binding-globulin was found to be strongly reduced in almost all women with hirsutism. Such reduction seemed to suggest the presence of increased amounts of free active testosterone in the blood of those patients. Determination of plasma-borne testosterone in cases of hirsutism is considered to be essential to both diagnosis of the endocrinological syndromes and monitoring of therapy. (author)

    Full Text Available Marty Hinz,1 Alvin Stein,2 Ted Cole3 1Clinical Research, NeuroResearch Clinics, Cape Coral, FL, 2Stein Orthopedic Associates, Plantation, FL, 3Cole Center for Healing, Cincinnati, OH, USA Abstract: When ʟ-dopa use began in the early 1960s for the treatment of Parkinson's disease, nausea and reversible dyskinesias were experienced as continuing side effects. Carbidopa or benserazide was added to ʟ-dopa in 1975 solely to control nausea. Subsequent to the increasing use of carbidopa has been the recognition of irreversible dyskinesias, which have automatically been attributed to ʟ-dopa. The research into the etiology of these phenomena has identified the causative agent of the irreversible dyskinesias as carbidopa, not ʟ-dopa. The mechanism of action of the carbidopa and benserazide causes irreversible binding and inactivation of vitamin B6 throughout the body. The consequences of this action are enormous, interfering with over 300 enzyme and protein functions. This has the ability to induce previously undocumented profound antihistamine dyskinesias, which have been wrongly attributed to ʟ-dopa and may be perceived as irreversible if proper corrective action is not taken.

Both drugs irreversibly bind to and permanently deactivate pyridoxal 5'-phosphate (PLP, the active form of vitamin B6, and PLP-dependent enzymes. PLP is required for the function of over 300 enzymes and proteins. Virtually every major system in the body is impacted directly or indirectly by PLP. The administration of carbidopa and benserazide potentially induces a nutritional catastrophe. During the first 15 years of prescribing L-dopa, a decreasing Parkinson's disease death rate was observed. Then, in 1976, 1 year after US Food and Drug Administration approved the original L-dopa/carbidopa combination drug, the Parkinson's disease death rate started increasing. This trend has continued to the present, for 38 years and counting. The previous literature documents this increasing death rate, but no hypothesis has been offered concerning this trend. Carbidopa is postulated to contribute to the increasing Parkinson's disease death rate and to the classification of Parkinson's as a progressive neurodegenerative disease. It may contribute to L-dopa tachyphylaxis.Keywords: L-dopa, levodopa, vitamin B6, pyridoxal 5'-phosphate

    We use stochastic volatility models to describe the evolution of an asset price, its instantaneous volatility and its realized volatility. In particular, we concentrate on the Stein and Stein model (SSM) (1991) for the stochastic asset volatility and the Heston model (HM) (1993) for the stochastic asset variance. By construction, the volatility is not sign definite in SSM and is non-negative in HM. It is well known that both models produce closed-form expressions for the prices of vanilla option via the Lewis-Lipton formula. However, the numerical pricing of exotic options by means of the finite difference and Monte Carlo methods is much more complex for HM than for SSM. Until now, this complexity was considered to be an acceptable price to pay for ensuring that the asset volatility is non-negative. We argue that having negative stochastic volatility is a psychological rather than financial or mathematical problem, and advocate using SSM rather than HM in most applications. We extend SSM by adding volatility jumps and obtain a closed-form expression for the density of the asset price and its realized volatility. We also show that the current method of choice for solving pricing problems with stochastic volatility (via the affine ansatz for the Fourier-transformed density function) can be traced back to the Kelvin method designed in the 19th century for studying wave motion problems arising in fluid dynamics.

    The physical problem studied is the transient non-boiling heat transfer of a cylindrical fuel rod consisting of fuel, gap, and cladding to a steady, fully developed turbulent flow. The fuel pin is assumed to be located in the interior region of a subassembly with regular triangular or square arrangements. The turbulent velocity field as well as turbulent transport properties are specified as functions of the coordinates normal to the axial flow direction. The heat generation within the fuel may be specified as an arbitrary function of the three spatial coordinates and time. A digital computer program has been developed. On the basis of finite-difference techniques, to solve the governing partial differential equations with their associated subsidiary conditions. Results have been obtained for a series of exponential power transients of interest to safety of liquid-metal and water cooled nuclear reactors. The general physical features of transient convective heat transfer as explored by previous investigators have qualitatively been substantiated by the present analysis. Emphasis has been devoted to investigate the differences of heat-transfer (coefficient) results from multi-region analysis including a realistic fuel rod model and single-region analysis for the coolant region only. A comparison with the engineering relationships for turbulent liquid-metal cooling by Stein, which are an extension of the heat transfer coefficient concept to account for transient heat fluxes, clearly demonstrates that, at the parameters studied, Stein's approach tends to largely overestimate the convective heat transfer at early times

    The brightest source of energetic neutral atoms (ENAs) at energies >1keV is low altitude emission (LAE) from ~200-400km near auroral latitudes where precipitating energetic ions undergo multiple atomic collisions with the monatomic (O) exosphere. This emission is many times brighter than that from the high-altitude ring current region where the energetic ions interact only weakly with the much less dense monatomic (H) hydrogen geocorona. The recently selected NSF CubeSat mission CINEMA [Lin et al., this special session] has, as part of its science payload (STEIN), an ENA imager covering energies 4-100keV. From a high-inclination ~800km orbit, STEIN will view the LAE four times during every 90 minutes. The NASA TWINS stereo ENA imagers (2-40keV) will also view the LAE from their Molniya orbits (apogee radius~7Re). We have been analyzing the TWINS ENA images of LAE and comparing them with in situ ion measurements (1-40keV) from DMSP spacecraft when their tracks take them under the ion precipitation regions imaged by TWINS. We have developed an ENA emissivity function that relates the directionally-dependent emergent ENA spectrum to that of the precipitating ions. The TWINS/DMSP direct comparisons show good agreement. We offer suggestions on joint observing strategies for CINEMA, TWINS and DMSP after the CINEMA launch in the second half of 2011.

Stein, il s'agit du « rapt » de son fiancé par Anne-Marie Stretter, le soir du bal à T. Beach. Pour G.H., c’est la vision d'un cafard dans la chambre de bonne qui entraîne une véritable aventure existentialiste. Ces deux événements ont des conséquences dévastatrices pour les deux personnages.

    Triplets of identical cubesats will be built to carry out the following scientific objectives: i) multi-observations of ionospheric ENA (Energetic Neutral Atom) imaging, ii) ionospheric signature of suprathermal electrons and ions associated with auroral acceleration as well as electron microbursts, and iii) complementary measurements of magnetic fields for particle data. Each satellite, a cubesat for ion, neutral, electron, and magnetic fields (CINEMA), is equipped with a suprathermal electron, ion, neutral (STEIN) instrument and a 3-axis magnetometer of magnetoresistive sensors. TRIO is developed by three institutes: i) two CINEMA by Kyung Hee University (KHU) under the WCU program, ii) one CINEMA by UC Berkeley under the NSF support, and iii) three magnetometers by Imperial College, respectively. Multi-spacecraft observations in the STEIN instruments will provide i) stereo ENA imaging with a wide angle in local times, which are sensitive to the evolution of ring current phase space distributions, ii) suprathermal electron measurements with narrow spacings, which reveal the differential signature of accelerated electrons driven by Alfven waves and/or double layer formation in the ionosphere between the acceleration region and the aurora, and iii) suprathermal ion precipitation when the storm-time ring current appears. In addition, multi-spacecraft magnetic field measurements in low earth orbits will allow the tracking of the phase fronts of ULF waves, FTEs, and quasi-periodic reconnection events between ground-based magnetometer data and upstream satellite data.

The patient was treated with a protocol that utilized serotonin and dopamine amino acid precursors administered under the guidance of organic cation transporter assay interpretation.Results: Within 5 days of achieving the necessary balance of serotonin and dopamine, the patient experienced remission of symptoms. This remission has been sustained without the use of any Crohn's disease medications.Conclusion: In Crohn's disease, it is known that there is an increase of both synthesis and tissue levels of serotonin in specific locations. It is asserted that this is prima facie evidence of a significant imbalance in the serotonin–dopamine system, leading to serotonin toxicity. The hypothesis formulated is that improperly balanced serotonin and dopamine transport, synthesis, and metabolism is a primary defect contributing to the pathogenesis of Crohn's disease.Keywords: serotonin, dopamine, organic cation transporters, OCT

    Full Text Available In recent years, there has been an increasing number of studies on carrion fly communities due to their medical importance and as a consequence of the large number of studies on forensic entomology. Surprisingly few studies have adressed with the asynantropic flies of the Amazon, and none were done in Colombia. A faunistic study of asynantropic flies of the families Calliphoridae, Sarcophagidae, Muscidae and Fannidae in three different landscapes of the Colombian Amazon is presented, trapping effectiveness is assessed, and the first record of Mesembrinella batesi (Aldrich, 1922 and Fannia femoralis (Stein, 1897 from Colombia is reported.Apesar de existir uma quantidade considerável de estudos sobre dípteros decompositores devido a sua importância medica e ao avanço da entomologia forense, poucos dizem respeito as moscas asinantrópicas na Amazônia e nada foi feito na Colômbia.

    2014-01-01

    In a prior study (Stein et al., 2013), we reported that rats pre-exposed to delayed rewards made fewer impulsive choices, but consumed more alcohol (12% wt/vol), than rats pre-exposed to immediate rewards. To understand the mechanisms that produced these findings, we again pre-exposed rats to either delayed (17.5 s; n = 32) or immediate (n = 30) rewards. In post-tests, delay-exposed rats made significantly fewer impulsive choices at both 15- and 30-s delays to a larger, later food reward than the immediacy-exposed comparison group. Behavior in an open-field test provided little evidence of differential stress exposure between groups. Further, consumption of either 12% alcohol or isocaloric sucrose in subsequent tests did not differ between groups. Because Stein et al. introduced alcohol concentration gradually (3–12%), we speculate that their group differences in 12% alcohol consumption were not determined by alcohol’s pharmacological effects, but by another variable (e.g., taste) that was preserved as an artifact from lower concentrations. We conclude that pre-exposure to delayed rewards generalizes beyond the pre-exposure delay; however, this same experimental variable does not robustly influence alcohol consumption. PMID:25418607

  11. Response of the agile antechinus to habitat edge, configuration and condition in fragmented forest.

    Christopher P Johnstone

    Full Text Available Habitat fragmentation and degradation seriously threaten native animal communities. We studied the response of a small marsupial, the agile antechinus Antechinus agilis, to several environmental variables in anthropogenically fragmented Eucalyptus forest in south-east Australia. Agile antechinus were captured more in microhabitats dominated by woody debris than in other microhabitats. Relative abundances of both sexes were positively correlated with fragment core area. Male and female mass-size residuals were smaller in larger fragments. A health status indicator, haemoglobin-haematocrit residuals (HHR, did not vary as a function of any environmental variable in females, but male HHR indicated better health where sites' microhabitats were dominated by shrubs, woody debris and trees other than Eucalyptus. Females were trapped less often in edge than interior fragment habitat and their physiological stress level, indicated by the neutrophil/lymphocyte ratio in peripheral blood, was higher where fragments had a greater proportion of edge habitat. The latter trend was potentially due to lymphopoenia resulting from stress hormone-mediated leukocyte trafficking. Using multiple indicators of population condition and health status facilitates a comprehensive examination of the effects of anthropogenic disturbances, such as habitat fragmentation and degradation, on native vertebrates. Male agile antechinus' health responded negatively to habitat degradation, whilst females responded negatively to the proportion of edge habitat. The health and condition indicators used could be employed to identify conservation strategies that would make habitat fragments less stressful for this or similar native, small mammals.

    Full Text Available Aim: The aim of the present study was to investigate the viability of lactic acid bacteria isolated from traditional cheeses and cocultured in Iranian white cheese during ripening. Materials and Methods: A total of 24 samples were isolated from 8 types of traditional cheeses in West Azerbaijan, Iran. Isolated species were cocultured with starter bacteria during the production of Iranian white cheese, and their viability was investigated up to 60 days of the refrigerated storage. Results: Of 118 isolates of Lactobacillus, 73 isolates (62% were confirmed as facultative heterofermentative and 45 isolates (38% as obligate homofermentative. Of the facultative heterofermentatives, 28 isolates (24% were Lactobacillus plantarum, 24 isolates (20% were Lactobacillus casei, and 21 isolates (18% were Lactobacillus agilis. Obligate homofermentatives were Lactobacillus delbrueckii (21%, Lactobacillus helveticus (14%, and Lactobacillus salivarius (3%. L. plantarum, L. casei and L. helveticus were found in high enough levels (106 CFU/g. Conclusion: According to the obtained data, it is recommended that complex starters such as L. helveticus, L. plantarum, and L. casei can be used in industrial productions of cheese to obtain exclusive properties of traditional cheeses.

    Full Text Available The present study acknowledges the diversity of fossil marsupials from the Gruta dos Moura cave, as well as environmental and climatic aspects during the Quaternary. The results show that this is the largest diversity of Pleistocene marsupials recorded in a single cave: Didelphis albiventris, D. aurita, Gracilinanus agilis, G. microtarsus, Marmosa murina, Monodelphis brevicaudata, M. domesticaand Sairadelphys tocantinensis. Furthermore, the described specimens are also part of the only fossil assemblage unequivocally referable to the late Pleistocene. Paleontological studies suggest an intimate association with dry and open environments with high abundance of water sources. Since most of the identified taxa are characteristic of open forests and gallery forests, this could represent the actual environment around the Gruta dos Moura cave. Recent studies identified sympatric occurrences between species from open and dry environments and species from humid forests that were identified among our material and are characteristic of humid regions. Therefore, these species could inhabit gallery forests and capons, or even ecotones, inside a dry and open environment. Moreover, the extinction of Sairadelphyscould also indicate that the climatic and environmental conditions changed or that the past environment was more heterogeneous than the current environment of the region.

    Full Text Available The Atlantic Rain forest, which is considered the second largest pluvial forest in the American continent, has had an estimated 93% of its original area destroyed. Although studies concerning the herpetofaunal diversity in this biome have been intensified in the past years, its diversity is still underestimated. The Nucleo Experimental de Iguaba Grande (NEIG is included in an Environmental Protection Area (APA de Sapeatiba in the Iguaba Grande municipality, Rio de Janeiro state, Brazil (22º 51' S and 42º 10' W. The goal of this study was to conduct an inventory of the reptile and amphibian species that occur in this area between July 2008 and December 2009. We recorded 19 species of amphibians (18 anurans and one caecilian and 15 species of reptiles (three lizards, 11 snakes and one amphisbaenian. Leptodactylus latrans and L. mystacinus had the highest capture rates among amphibians captured, and among reptiles, Ameiva ameiva, Hemidactylus mabouia and Mabuya agilis had the highest capture rates. Rarefaction curves for both amphibians and reptiles did not reach the asymptote, indicating that the species richness in the NEIG is still underestimated.

Testudo graeca was indicated by mistake at Sfântu Gheorghe (probably the authors saw the species in some places from the continental plateau nearby of Sfântu Gheorghe branch, not inside the Danube Delta. Lacerta viridis was mentioned in the so-called “maritime Delta” and at the ruins of Histria fortress (due to confusion with specimens of Lacerta agilis. Also, Podarcis muralis was “recorded” at the ruins of Histria fortress (due to misidentification of specimens belonging to species P. taurica. A corps of snake found at Letea forest was considered by mistake as belonging to species Eryx jaculus. In several official reports (grey literature the species Elaphe longissima (Zamenis longissimus was mentioned by mistake as occurring at Letea forest. Elaphe (quatuorlineata sauromates was “recorded” at the ruins of Histria fortress and at Sfântu Gheorghe due to confusion with specimens belonging to other snake species. Specimens of Vipera urisnii from the Danube Delta were considered as belonging to the species Vipera berus. Also, Vipera ursinii was metioned by mistake at Caraorman marine levee and at Chituc marine levee, based only on the idea that if the species occurs on other marine levees, it has to be present on these two marine levees, too.

    The sand lizard, Lacerta agilis, is a classical model species in herpetology. Its adult skull anatomy and its embryonic development are well known. The description of its fully formed primordial skull by Ernst Gaupp, in 1900, was a key publication in vertebrate morphology and influenced many comparative embryologists. Based on recent methodological considerations, we restudied the early cranial development of this species starting as early as the formation of mesenchymal condensations up to the fully formed chondrocranium. We traced the formation of the complex chondrocranial architecture in detail, clarified specific homologies for the first time, and uncovered major differences to old textbook descriptions. Comparison with other lacertid lizards revealed a very similar genesis of the primordial skull. However, we detected shifts in the developmental timing of particular cartilaginous elements, mainly in the nasal region, which may correlate to specific ecological adaptation in the adults. Late timing of nasal elements might be an important innovation for the successful wide range distribution of the well-known sand lizard. © 2018 Wiley Periodicals, Inc.

    The riverine barrier model suggests that rivers play a significant role in separating widespread organisms into isolated populations. In this study, we used a comparative approach to investigate the phylogeography of 6 didelphid marsupial species in central Brazil. Specifically, we evaluate the role of the mid-Araguaia River in differentiating populations and estimate divergence time among lineages to assess the timing of differentiation of these species, using mitochondrial DNA sequence data. The 6 didelphid marsupials revealed different intraspecific genetic patterns and structure. The 3 larger and more generalist species, Didelphis albiventris, Didelphis marsupialis, and Philander opossum, showed connectivity across the Araguaia River. In contrast the genetic structure of the 3 smaller and specialist species, Gracilinanus agilis, Marmosa (Marmosa) murina, and Marmosa (Micoureus) demerarae was shaped by the mid-Araguaia. Moreover, the split of eastern and western bank populations of the 2 latter species is consistent with the age of Araguaia River sediments formation. We hypothesize that the role of the Araguaia as a riverine barrier is linked to the level of ecological specialization among the 6 didelphid species and differences in their ability to cross rivers or disperse through the associated habitat types. © The American Genetic Association 2015.

    A mixture of human-derived probiotic strains of Lactobacillus acidophilus, L. agilis and L. rhamnosus was used as a probiotic culture in ice cream manufacture. Viability and survival of these probiotic cultures were investigated in two different ice cream formulations. Ice cream with sucrose and ice cream with aspartame were prepared and each of these was divided into two subgroups: one with direct addition of the probiotic culture and one with milk fermented by the same probiotic culture. Ice cream samples were stored at -20 degrees C for 6 months and the survival rate of cultures were determined monthly. Probiotic cultures underwent tests for resistance to bile salts, antibiotics, acidic conditions; they were found to be highly resistant to such challenges. Chemical analysis of ice cream samples, such as determination of acidity, pH and solid matter, was also performed. The probiotic cultures remained unchanged in ice cream stored for up to 6 months regardless of the sweeteners used. Using probiotic cultures in ice cream mixes did not alter the characteristics of the product.

    We explored the ontogenetic dynamics of the morphological and allometric disparity in the cranium shapes of twelve lacertid lizard species. The analysed species (Darevskia praticola, Dinarolacerta mosorensis, Iberolacerta horvathi, Lacerta agilis, L. trilineata, L. viridis, Podarcis erhardii, P. melisellensis, P. muralis, P. sicula, P. taurica and Zootoca vivipara) can be classified into different ecomorphs: terrestrial lizards that inhabit vegetated habitats (habitats with lush or sparse vegetation), saxicolous and shrub-climbing lizards. We observed that there was an overall increase in the morphological disparity (MD) during the ontogeny of the lacertid lizards. The ventral cranium, which is involved in the mechanics of jaw movement and feeding, showed higher levels of MD, an ontogenetic shift in the morphospace planes and more variable allometric patterns than more conserved dorsal crania. With respect to ecology, the allometric trajectories of the shrub-climbing species tended to cluster together, whereas the allometric trajectories of the saxicolous species were highly dispersed. Our results indicate that the ontogenetic patterns of morphological and allometric disparity in the lacertid lizards are modified by ecology and functional constraints and that the identical mechanisms that lead to intraspecific morphological variation also produce morphological divergence at higher taxonomic levels. © 2012 The Authors.

    DR. Scheibler

    Full Text Available We inventoried terrestrial small mammals in an agricultural area in southern Brazil by using trapping and prey consumed by Barn Owls (Tyto alba and White-tailed Kites (Elanus leucurus. Small mammals were trapped in three habitat types: corn fields, uncultivated fields ("capoeiras", and native forest fragments. A total of 1,975 small mammal specimens were trapped, another 2,062 identified from the diet of Barn Owls, and 2,066 from the diet of White-tailed Kites. Both trapping and prey in the predators' diet yielded 18 small mammal species: three marsupials (Didelphis albiventris, Gracilinanus agilis, and Monodelphis dimidiata and 15 rodents (Akodon paranaensis, Bruceppatersonius iheringi, Calomys sp., Cavia aperea, Euryzygomatomys spinosus, Holochilus brasiliensis, Mus musculus, Necromys lasiurus, Nectomys squamipes, Oligoryzomys nigripes, Oryzomys angouya, Oxymycterus sp.1, Oxymycterus sp.2, Rattus norvegicus, and Rattus rattus (Linnaeus, 1758. The greatest richness was found in the uncultivated habitat. We concluded that the three methods studied for inventorying small mammals (prey in the diet of Barn Owls, White-tailed Kites, and trapping were complementary, since together, rather than separately, they produced a better picture of local richness.

  1. Inbreeding avoidance, patch isolation and matrix permeability influence dispersal and settlement choices by male agile antechinus in a fragmented landscape.

    Animal dispersal is highly non-random and has important implications for the dynamics of populations in fragmented habitat. We identified interpatch dispersal events from genetic tagging, parentage analyses and assignment tests and modelled the factors associated with apparent emigration and post-dispersal settlement choices by individual male agile antechinus (Antechinus agilis, a marsupial carnivore of south-east Australian forests). Emigration decisions were best modelled with on data patch isolation and inbreeding risk. The choice of dispersal destination by males was influenced by inbreeding risk, female abundance, patch size, patch quality and matrix permeability (variation in land cover). Males were less likely to settle in patches without highly unrelated females. Our findings highlight the importance of individual-level dispersal data for understanding how multiple processes drive non-randomness in dispersal in modified landscapes. Fragmented landscapes present novel environmental, demographic and genetic contexts in which dispersal decisions are made, so the major factors affecting dispersal decisions in fragmented habitat may differ considerably from unfragmented landscapes. We show that the spatial scale of genetic neighbourhoods can be large in fragmented habitat, such that dispersing males can potentially settle in the presence of genetically similar females after moving considerable distances, thereby necessitating both a choice to emigrate and a choice of where to settle to avoid inbreeding. © 2013 The Authors.

    Amblyomma rotundatum Koch is a parthenogenetic tick usually associated with reptiles and amphibians. However, relatively few studies on occurrences of ticks in wild reptile populations in Brazil have been produced. The aim of this study was to analyze the presence of ticks associated with reptile species in the Grussaí restinga, in the municipality of São João da Barra, state of Rio de Janeiro, Brazil. Between December 2010 and January 2011, 131 individuals belonging to nine species of reptiles of the order Squamata were sampled: the lizards Tropidurus torquatus (n = 51), Hemidactylus mabouia (n = 25), Mabuya agilis (n = 30), Mabuya macrorhyncha (n = 6), Cnemidophorus littoralis (n = 5) and Ameiva ameiva (n = 10); and the snakes Philodryas olfersii (n = 2), Oxyrhopus rhombifer (n = 1) and Micrurus corallinus (n = 1). The only tick species found to be associated with any of the reptiles sampled was A. rotundatum. One adult female was detected on one individual of the lizard A. ameiva, one nymph on one individual of the lizard T. torquatus and four nymphs on one individual of the snake P. olfersii. This study is the first record of parasitism of A. rotundatum involving the reptiles T. torquatus and P. olfersii as hosts. Our results suggest that in the Grussaí restinga habitat, A. rotundatum may use different species of reptiles to complete its life cycle.

    Several reports have highlighted that many plant growth-promoting endophytic bacteria (PGPE) can assist their host plants in coping with various biotic and abiotic stresses. However, information about the PGPE colonizing in the halophytes is still scarce. This study was designed to isolate and characterize PGPE from salt-accumulating halophyte Salicornia europaea grown under extreme salinity and to evaluate in vitro the bacterial mechanisms related to plant growth promotion. A total of 105 isolates were obtained from the surface-sterilized roots, stems, and assimilation twigs of S. europaea. Thirty-two isolates were initially selected for their ability to produce 1-aminocyclopropane-1-carboxylate deaminase as well as other properties such as production of indole-3-acetic acid and phosphate-solubilizing activities. The 16S rRNA gene-sequencing analysis revealed that these isolates belong to 13 different genera and 19 bacterial species. For these 32 strains, seed germination and seedling growth in axenically grown S. europaea seedlings at different NaCl concentrations (50-500 mM) were quantified. Five isolates possessing significant stimulation of the host plant growth were obtained. The five isolates were identified as Bacillus endophyticus, Bacillus tequilensis, Planococcus rifietoensis, Variovorax paradoxus, and Arthrobacter agilis. All the five strains could colonize and can be reisolated from the host plant interior tissues. These results demonstrate that habitat-adapted PGPE isolated from halophyte could enhance plant growth under saline stress conditions.

    Full Text Available Salmonella enterica serovar Infantis (S. Infantis is a common source of foodborne gastroenteritis worldwide. Here, Lactobacillus rhamnosus GG (LGG was administrated to weaned piglets for 1 week before S. Infantis challenge. S. Infantis caused decreased ileal mucosal microbiota diversity, a dramatic Lactobacillus amylovorus bloom, and decreased abundance of Arsenicicoccus, Janibacter, Kocuria, Nocardioides, Devosia, Paracoccus, Psychrobacter, and Weissella. The beneficial effect of LGG correlated with the moderate expansion of L. amylovorus, L. agilis, and several members of the phyla Proteobacteria, Firmicutes, and Bacteroidetes. S. Infantis translocation to the liver was decreased in the LGG-pretreated piglets. An in vitro model of LGG and S. Infantis co-incubation (involving the porcine intestinal epithelial cell line IPEC-J2 was established, and nalidixic acid was used to kill the extracellular S. Infantis. LGG suppressed the initial S. Infantis invasion in the IPEC-J2 cells and deceased the rate of cell death. LGG inhibited S. Infantis-induced autophagy and promoted epidermal growth factor receptor (EGFR and Akt phosphorylation in both the ileum and IPEC-J2 cells. Our findings suggest that LGG inhibited S. Infantis-induced autophagy by promoting EGFR-mediated activation of the negative mediator Akt, which, in turn, suppressed intestinal epithelial cell death and thus restricted systemic S. Infantis infection. LGG can restore the gut microbiota balance and preserve the autophagy-related intestinal epithelial barrier, thereby controlling infections.

    Myotonic dystrophy (DM) is due to a genomic instability of a trinucleotide [AGC]n motif, located at the 3{prime} UTR region of a protein-kinase gene (myotonin protein kinase, MT-PK). The [AGC] repeat is meiotically and mitotically unstable, and it is directly related to the manifestations of the disorder. Although a gene dosage effect of the MT-PK has been demonstrated n DM muscle, the mechanism(s) by which the intragenic repeat expansion leads to disease is largely unknown. This non-standard mutational event could reflect an evolutionary mechanism widespread among animal genomes. We have isolated and sequenced the complete 3{prime}UTR region of the MT-PK gene in seven primates (macaque, orangutan, gorilla, chimpanzee, gibbon, owl monkey, saimiri), and examined by comparative sequence nucleotide analysis the [AGC]n intragenic repeat and the surrounding nucleotides. The genomic organization, including the [AGC]n repeat structure, was conserved in all examined species, excluding the gibbon (Hylobates agilis), in which the [AGC]n upstream sequence (GGAA) is replaced by a GA dinucleotide. The number of [AGC]n in the examined species ranged between 7 (gorilla) and 13 repeats (owl monkeys), with a polymorphism informative content (PIC) similar to that observed in humans. These results indicate that the 3{prime}UTR [AGC] repeat within the MT-PK gene is evolutionarily conserved, supporting that this region has important regulatory functions.

    Theoretical models for the evolution of life-history traits assume a genetic basis for a significant proportion of the phenotypic variance observed in characteristics such as hatching date and offspring size. However, recent experimental work has shown that much of the phenotypic variance in hatchling reptiles is induced by nongenetic factors, such as maternal nutrition and thermoregulation, and the physical conditions experienced during embryogenesis. Thus, there is no unambiguous evidence for strictly genetic (intraspecific) influences on the phenotypes of hatchling reptiles. We report results from a technique that uses a genetic marker trait and DNA fingerprinting to determine paternity of offspring from multiply sired clutches of European sand lizards, Lacerta agilis. By focusing on paternal rather than maternal effects, we show that hatchling genotypes exert a direct influence on the duration of incubation, the size (mass, snout-vent length) and shape (relative tail length) of the hatchling, and subsequent growth rates of the lizard during the first 3 mo of life. Embryos with genes that code for a few days' delay in hatching are thereby larger when they hatch, having undergone further differentiation (and hence, have changed in bodily proportions), and are able to grow faster after hatching. Our data thus provide empirical support for a crucial but rarely tested assumption of life-history theory, and illuminate some of the proximate mechanisms that produce intraspecific variation in offspring phenotypes. © 1996 The Society for the Study of Evolution.

    Full Text Available In other to identify the implication of human handling of packaged sausage rolls after production, a microbiological safety evaluation was carried out on sausage rolls sold on street and in shops. Among the sausage rolls, gala purchased from street vendors has the highest bacterial load of 2.82 × 104 CFU/g and 4.3 × 106 spore/g of fungal load, followed by meaty with bacterial load of 1.71 × 104 CFU/g and fungal load of 1.6 × 105 spore/g and was least in rite sausage roll with 1.46 × 104 CFU/g and 1 × 105 spore/g bacterial and fungal loads respectively. Seventeen bacteria species were isolated from both street vended and shop sold sausage rolls, the isolates identified including: Bacillus cereus, Acinetobacter calcoaceticus, Alcaligenes faecalis, Citrobacter freundii, Klebsiella ozaenae, Staphylococcus epidermidis, Enterobacter aerogenes, Staphylococcus aureus, Aeromonas hydrophila, Plesiomonas shigelloides, Moraxella catarhalis, Bacillus substilis, Escherichia coli, Salmonella typhi, Aeromonas anaerogenes, Aerococcus viridans and Azomonas agilis. Five fungi species were isolated from street vended sausage rolls only. The fungal species are Penicillium notatum, Aspergillus parasiticus, Aspergillus flavus, Penicillium italicum and Gliocephalis spp. From this study, street vended samples have higher microbial contamination than shop sold sausage rolls due to improper handling during sales.

    Full Text Available Nematode assemblages associated to three species of lizards of the genus Mabuya Fitzinger, 1826 [M. agilis (Raddi, 1823, M. caissara Rebouças-spieker, 1974 and M. macrorhyncha Hoge, 1946] from three mainland sites and three island sites along the eastern Brazilian coast were analyzed. A total of six nematode species were recorded, with total nematode richness varying from one to four and overall nematode prevalences varying from 6.7% to 90.5% among host populations. Number of nematode species per host individual (including all hosts, infected and uninfected varied among host populations from 0.07 to 1.05, but most infected lizards in all six host populations harbored a single nematode species. Both insular and continental populations of Mabuya spp. exhibited generally poor nematode assemblages, and no clear tendency for insular host populations to have more depauperate nematode faunas and/or lower infection rates compared to mainland ones (or vice versa was evident on the basis of the present data.

    Scinax melanodactylus is a small treefrog distributed within the Tropical Atlantic morphoclimatic domain (see Ab'Sáber 1977 for South American morphoclimatic domains), from northern Espírito Santo state to Sergipe state in Brazil (Lourenço et al. 2014). The species is usually found inhabiting herbaceous and shrubby xerophytic vegetation (e.g. terrestrial tank-bromeliads) from sandy plains of beach ridges known in Brazil as Restingas (see Rocha et al. 2007 for a Restinga definition), and also the edge of forest areas with temporary ponds and/or permanent lakes and streams near these environments (Bastazini et al. 2007, as Scinax agilis; Lourenço et al. 2014). Scinax melanodactylus is currently placed in the S. catharinae species group (Lourenço et al. 2014), which in turn is included in the S. catharinae clade (sensu Faivovich et al. 2005). The S. catharinae clade is currently comprised of 46 species, 33 placed in the catharinae group and 13 in the perpusillus group (Faivovich et al. 2010, Silva & Alves-da-Silva 2011, Lourenço et al. 2014, Frost 2015). From these, 32 species have tadpoles with external morphology and oral disc formerly described. Here, we describe the external morphology, oral disc and color patterns of the previously unknown tadpole of S. melanodactylus.

    2017-12-01

    The application of Re-Os isotope geochemistry to dating single oils is a nascent field [1,2]. Challenges include dissection of oils into asphaltene-maltene (ASPH-MALT) components in a way that preserves meaningful chronologic and source information. Significantly, oil-water mixing rapidly transfers Os to the oil, while Re exchange is sluggish [3]. The Os initial ratio of the oil is shifted in the direction of Os carried in the aqueous fluid, whereas the Re-Os isotopic age is preserved. We show that this phenomenon is operative in natural systems. Further, we show that deserpentinization of old oceanic slabs [4], may be linked to expulsion of Os-enriched waters into overlying sedimentary sections - a process that may be of fundamental importance for oil generation. This conclusion does not diminish the role of traditional organic-rich shales as source rocks for the hydrocarbon, but shows that external fluids are essential to petroleum generation. Moreover, the external fluids may be an important driver for expulsion and migration of oils. We have taken apart several petroleum systems from source rock, to residual oil, to tar mat development, to in situ live oil, through to produced oil. In many cases, a fluid with low 187Os/188Os - unlike that of normal basinal brines - provides a critical component to the oil-water mixture.

    Solar Orbiter is the next heliospheric mission sponsored by ESA. The launch is planned for 2017 and it will be as close as 0.28 AU from the Sun. One of the instruments for Solar Orbiter is the Energetic Particle Detector (EPD) responsible for measuring energies from 2 keV to 200 MeV/n. EPD consists of four detectors, Electron Proton Telescope (EPT), High Energy Telescope (HET), SupraThermal Electrons, Ions, & Neutrals (STEIN), and Suprathermal Ion Spectrograph (SIS), plus the Instrument Control Unit called ICU. The Space Research Group of the University of Alcalá in Spain is the responsible for developing the ICU. In this work we present the development status of the ICU after the Critical Design Review. We also address the planned activities for the next year including the development of the Engineering and Qualification Model (EQM) and Flight Model (PM). Special focus is paid to the software and verification & validation activities.

    Differential scanning calorimetry measurements have revealed different thermal transitions in cod and tuna samples. Transition temperatures detected Lit -11degreesC, -15degreesC and -21degreesC were highly dependent on the annealing temperature. In tuna muscle an additional transition was observed...... at -72degreesC. This transition appeared differently than the thermal events observed at higher temperatures, as it spanned a broad temperature interval of 25degreesC. The transition was comparable to low-temperature glass transitions reported in protein-rich systems. No transition at this low...... temperature was detected in cod samples. The transitions observed at higher temperatures (-11degreesC to -21degreesC) may possibly stein from a glassy matrix containing muscle proteins. However, the presence of a glass transition at - 11degreesC was in disagreement with the low storage stability at -18degrees...

    Full Text Available ABSTRACT This study aimed to evaluate the effect of mechanical damage on the hysteresis of beans with induced mechanical damage under different conditions of temperature and relative humidity. Beans (Phaseolus vulgaris L. harvested manually with 35% water content (w.b. were used. Part of this product was subjected to induced mechanical damage by Stein Breakage Tester and controlled drying (damaged and control sample, for sorption processes. The sorption isotherms of water were analyzed for different temperature conditions: 20, 30, 40 and 50 oC; and relative humidity: 0.3; 0.4; 0.5; 0.7 and 0.9 (decimal. Equilibrium moisture content data were correlated with six mathematical models, and the Modified Oswin model was the one that best fitted to the experimental data. According to the above mentioned isotherms, it was possible to observe the phenomenon of hysteresis of damaged and control samples, and this phenomenon was more pronounced in control ones.

The results from analysis using the HOMOG program, allowing for heterogeneity under the reduced penetrance model, gave a maximum LOD score of 1.85 for ApoC2, 0.41 for BCL3, 0.03 for D19S178, and 1.72 for multipoint analysis in the interval. For the affecteds-only model, the values are 1.96 for ApoC2, 0.41 for BCL3, 0.01 for D19S178, and 1.44 for the multipoint analysis. 8 refs.

  1. Endometrial carcinoma occuring from polycystic ovary disease : A case report

    1996-01-01

    Endometrial carcinoma usually occurs in postmenopausal women ; less than 5% occurs in women under the age of 40. Up to one quarter of endometrial carcinoma patients below this age have PCO(polycystic ovary disease, Stein-Leventhal syndrome). The increased incidence of endometrial carcinoma in patients with PCO is related to chronic estrogenic stimulation. We report MR imaging in one case of endometrial carcinoma occuring in a 23 year old woman with PCO and had complained of hypermenorrhea for about three years. On T2-weighted MR image the endometrial cavity was seen to be distended with protruded endometrial masses of intermediate signal intensity, and the junctional zone was disrupted beneath the masses. Both ovaries were best seen on T2-weighted MR imaging and showed multiple small peripheral cysts and low signal-intensity central stroma

    A forensic entomological study was conducted using monkey carcasses (Macaca fascicularis Raffles) that were placed in either an outdoor or indoor environment at a coastal area in Tanjung Sepat, Selangor, Malaysia during May until August 2008. We collected pupae of Chrysomya rufifacies (Marquart) from the carcasses and kept them individually. The emergence of 13 parasitic microhymenopteran, from one of the pupae occurring within a week were identified as Exoristobia philippinensis Ashmead (Hymenoptera: Encyrtidae). Another observation was made whereby a pupa of C. rufifacies was predated by a muscid larva, Ophyra spinigera (Stein). The larva squeezed into the pupa and consumed the contents. This paper report C. rufifacies as a new host record for E. philippinensis in Malaysia and highlighted the predatory behavior of O. spinigera larva in natural environment.

  4. On groups of pl-homeomorphisms of the real line

    Bieri, Robert

    2016-01-01

    Richard Thompson's famous group F has the striking property that it can be realized as a dense subgroup of the group of all orientation-preserving homeomorphisms of the unit interval, but it can also be given by a simple 2-generator-2-relator presentation, in fact as the fundamental group of an aspherical complex with only two cells in each dimension. This monograph studies a natural generalization of F that also includes Melanie Stein's generalized F-groups. The main aims of this monograph are the determination of isomorphisms among the generalized F-groups and the study of their automorphism groups. This book is aimed at graduate students (or teachers of graduate students) interested in a class of examples of torsion-free infinite groups with elements and composition that are easy to describe and work with, but have unusual properties and surprisingly small presentations in terms of generators and defining relations.

  5. Arctic Ocean Paleoceanography and Future IODP Drilling

    2015-04-01

    Although the Arctic Ocean is a major player in the global climate/earth system, this region is one of the last major physiographic provinces on Earth where the short- and long-term geological history is still poorly known. This lack in knowledge is mainly due to the major technological/logistical problems in operating within the permanently ice-covered Arctic region which makes it difficult to retrieve long and undisturbed sediment cores. Prior to 2004, in the central Arctic Ocean piston and gravity coring was mainly restricted to obtaining near-surface sediments, i.e., only the upper 15 m could be sampled. Thus, all studies were restricted to the late Pliocene/Quaternary time interval, with a few exceptions. These include the four short cores obtained by gravity coring from drifting ice floes over the Alpha Ridge, where older pre-Neogene organic-carbon-rich muds and laminated biosiliceous oozes were sampled. Continuous central Arctic Ocean sedimentary records, allowing a development of chronologic sequences of climate and environmental change through Cenozoic times and a comparison with global climate records, however, were missing prior to the IODP Expedition 302 (Arctic Ocean Coring Expedition - ACEX), the first scientific drilling in the central Arctic Ocean. By studying the unique ACEX sequence, a large number of scientific discoveries that describe previously unknown Arctic paleoenvironments, were obtained during the last decade (for most recent review and references see Stein et al., 2014). While these results from ACEX were unprecedented, key questions related to the climate history of the Arctic Ocean remain unanswered, in part because of poor core recovery, and in part because of the possible presence of a major mid-Cenozoic hiatus or interval of starved sedimentation within the ACEX record. In order to fill this gap in knowledge, international, multidisciplinary expeditions and projects for scientific drilling/coring in the Arctic Ocean are needed. Key

  6. Effect of primary and secondary radicals on chain breaks in ribosomal RNA in E. coli ribosomes

    International Nuclear Information System (INIS)

    Singh, H.; Bishop, J.

    1984-01-01

    It has been shown previously that, in dilute aerated solutions, ribosomes are inactivated by OH radicals and by secondary radicals produced from added alcohols (Singh and Vadasz 1983 a). In de-aerated solutions, both radicalH and e - sub(aq) also inactivate ribosomes (Singh and Vadasz 1983 b). The results of these studies and other on different systems (Adams et al. 1973, Aldrich and Cundall 1969, Dewey and Stein 1970, Masuda et al. 1971, Nabben et al. 1982, 1983, Samuni et al. 1980, Singh and Singh 1982) have shown that damage to biological systems occurs by diverse mechanisms. One of these mechanisms involves chain breaks in RNA (Pollard and Weller 1967). The purpose of this study was to determine which of the primary and secondary radicals cause chain breaks in ribosomal RNA (rRNA) within the ribosomes. (author)

    Full Text Available Women photographers made considerable contributions to the ‘age of emulsion’ that transformed the way art history was practiced and taught early in the twentieth century. Among American women who made great efforts to record medieval monuments were Vida Hunt Francis, who worked in France c. 1905-15, and Lucy Warren Porter whose work has previously been attributed to her husband, Arthur Kingsley Porter. Georgiana Goddard King of Bryn Mawr College preceded Porter and others in documenting medieval and renaissance sites for the Hispanic Society of America. Her co-photographer Edith H. Lowber has until now been overlooked. The last book they planned together was edited and published posthumously and most of the illustrations they prepared for it remained unpublished. King also had a great interest in modern art, through her friendship with Gertrude Stein. Occasionally the photos recall cubism, and some of her writing verges on modernist écriture feminine.

  8. On the degrees of freedom of reduced-rank estimators in multivariate regression.

    Science.gov (United States)

    Mukherjee, A; Chen, K; Wang, N; Zhu, J

    We study the effective degrees of freedom of a general class of reduced-rank estimators for multivariate regression in the framework of Stein's unbiased risk estimation. A finite-sample exact unbiased estimator is derived that admits a closed-form expression in terms of the thresholded singular values of the least-squares solution and hence is readily computable. The results continue to hold in the high-dimensional setting where both the predictor and the response dimensions may be larger than the sample size. The derived analytical form facilitates the investigation of theoretical properties and provides new insights into the empirical behaviour of the degrees of freedom. In particular, we examine the differences and connections between the proposed estimator and a commonly-used naive estimator. The use of the proposed estimator leads to efficient and accurate prediction risk estimation and model selection, as demonstrated by simulation studies and a data example.

    Colin, Vincent; Stipsicz, András

    2014-01-01

    Symplectic and contact geometry naturally emerged from the mathematical description of classical physics. The discovery of new rigidity phenomena and properties satisfied by these geometric structures launched a new research field worldwide. The intense activity of many European research groups in this field is reflected by the ESF Research Networking Programme "Contact And Symplectic Topology" (CAST). The lectures of the Summer School in Nantes (June 2011) and of the CAST Summer School in Budapest (July 2012) provide a nice panorama of many aspects of the present status of contact and symplectic topology. The notes of the minicourses offer a gentle introduction to topics which have developed in an amazing speed in the recent past. These topics include 3-dimensional and higher dimensional contact topology, Fukaya categories, asymptotically holomorphic methods in contact topology, bordered Floer homology, embedded contact homology, and flexibility results for Stein manifolds.

    CERN Document Server

    Szilárd, ágnes

    2013-01-01

    The present publication contains a special collection of research and review articles on deformations of surface singularities, that put together serve as an introductory survey of results and methods of the theory, as well as open problems, important examples and connections to other areas of mathematics. The aim is to collect material that will help mathematicians already working or wishing to work in this area to deepen their insight and eliminate the technical barriers in this learning process. This also is supported by review articles providing some global picture and an abundance of examples. Additionally, we introduce some material which emphasizes the newly found relationship with the theory of Stein fillings and symplectic geometry.  This links two main theories of mathematics: low dimensional topology and algebraic geometry. The theory of normal surface singularities is a distinguished part of analytic or algebraic geometry with several important results, its own technical machinery, and several op...

  14. The effectiveness of using pictures in teaching young children about burn injury accidents.

    2015-11-01

    This study utilized the "story grammar" approach (Stein and Glenn, 1979) to analyze the within-corpus differences in recounting of sixty 6- and 7-year-old children, specifically whether illustrations (5-factor accident sequence) were or were not resorted to as a means to assist their narration of a home accident in which a child received a burn injury from hot soup. Our investigation revealed that the message presentation strategy "combining oral and pictures" better helped young children to memorize the story content (sequence of events leading to the burn injury) than "oral only." Specifically, the content of "the dangerous objects that caused the injury", "the unsafe actions that people involved took", and "how the people involved felt about the severity of the accident" differed significantly between the two groups.

    2018-01-01

    The NASA Kennedy Space Center (KSC) operates a 48-MHz Tropospheric/Stratospheric Doppler Radar Wind Profiler (TDRWP) on a continual basis generating wind profiles between 2-19 km in the support of space launch vehicle operations. A benefit of the continual operability of the system is the ability to provide unique observations of severe weather events such as hurricanes. Over the past two Atlantic Hurricane seasons the TDRWP has made high temporal resolution wind profile observations of Hurricane Irma in 2017 and Hurricane Matthew in 2016. Hurricane Irma was responsible for power outages to approximately 2/3 of Florida's population during its movement over the state(Stein,2017). An overview of the TDRWP system configuration, brief summary of Hurricanes Irma and Matthew storm track in proximity to KSC, characteristics of the tropospheric wind observations from the TDRWP during both events, and discussion of the dissemination of TDRWP data during the event will be presented.

    Brémaud, Pierre

    2017-01-01

    The emphasis in this book is placed on general models (Markov chains, random fields, random graphs), universal methods (the probabilistic method, the coupling method, the Stein-Chen method, martingale methods, the method of types) and versatile tools (Chernoff's bound, Hoeffding's inequality, Holley's inequality) whose domain of application extends far beyond the present text. Although the examples treated in the book relate to the possible applications, in the communication and computing sciences, in operations research and in physics, this book is in the first instance concerned with theory. The level of the book is that of a beginning graduate course. It is self-contained, the prerequisites consisting merely of basic calculus (series) and basic linear algebra (matrices). The reader is not assumed to be trained in probability since the first chapters give in considerable detail the background necessary to understand the rest of the book. .

  20. Systematic risk variations (beta convertible debenture brazilian companies

    Renata Drumond Pinto Coelho Antonino

    2010-01-01

    Full Text Available purpose of this article is to analyze the impact of issuing convertible debentures on the systematic risk of Brazilian companies. Some applied researches in the U.S. capital market (STEIN, 1992; LEWIS et al, 2002; RAI, 2005 indicate that convertible debentures may be used as an alternative financing source when adverse selection problem makes stock issuing unattractive financing source. The analysis of Brazilian companies that issued convertible debentures recorded in the period from 1998 to 2006 and that presented liquidity on the market indicated that variation in beta, on average, is positive. These results are coherent with the signaling hypothesis and with the absence of convertible debenture issuing in 2005 and 2006 on the Brazilian market. They also may be related to the precarious financial situation of issuing companies, observed by the analysis of some financial indicators in year of issue and in two pre- e post-issuing years.

    2010-06-01

    Full Text Available Fiction, as understood in the West, was not a strong part of the Tibetan literary tradition (Stein 1972, 251-2. Although Newman (1996, 411 has argued that certain literary works existed as early as the eighteenth century, most fictional texts in Tibet belonged to folklore and oral tradition. Beginning in the twentieth century, however, modern fiction and poetry has gradually emerged and even thrives in spite of continuing issues of literacy and education. As relative newcomers to the study of Tibetan writing, western scholars, many of whom approach Tibet from disciplines that emphasize religion or philosophy, tend to overlook modern fiction. This work, edited by Hartley and Schiaffini-Vedani, aims to fill this void and provide scholars with an introduction to the complexities of modern Tibetan literature and how it reflects and impacts the unique transnational and cross-cultural social context it is written in... ...

Una creatividad desconocida y que ahora, en un momento en que se postula la muerte de la filosofía, se desvela como la continuidad del pensamiento humano. Las filósofas inventan, recuperan, destruyen y vuelven a re-construir temas negados y reprimidos por la filosofía tradicional. Su subjetividad representa en sí misma la exaltación del otro, la presencia de una alteridad, de una forma de ver que pretende la búsqueda de la representación de la verdad, de la realidad.

    Nechaev, S K; Vasilyev, O A

    2004-01-01

    In our work we have reconsidered the old problem of diffusion at the boundary of an ultrametric tree from a 'number theoretic' point of view. Namely, we use the modular functions (in particular, the Dedekind η-function) to construct the 'continuous' analogue of the Cayley tree isometrically embedded in the Poincare upper half-plane. Later we work with this continuous Cayley tree as with a standard function of a complex variable. In the framework of our approach, the results of Ogielsky and Stein on dynamics in ultrametric spaces are reproduced semi-analytically or semi-numerically. The speculation on the new 'geometrical' interpretation of replica n → 0 limit is proposed

    This book presents a wide range of well-known and less common methods used for estimating the accuracy of probabilistic approximations, including the Esseen type inversion formulas, the Stein method as well as the methods of convolutions and triangle function. Emphasising the correct usage of the methods presented, each step required for the proofs is examined in detail. As a result, this textbook provides valuable tools for proving approximation theorems. While Approximation Methods in Probability Theory will appeal to everyone interested in limit theorems of probability theory, the book is particularly aimed at graduate students who have completed a standard intermediate course in probability theory. Furthermore, experienced researchers wanting to enlarge their toolkit will also find this book useful.

  7. 24-hour secretory pattern of dehydroisoandrosterone and dehydroisoandrosterone sulfate

    International Nuclear Information System (INIS)

    Rosenfeld, R.S.; Rosenberg, B.J.; Fukushima, D.K.; Hellman, L.

    1975-01-01

    Dehydroisoandrosterone (DHA) and cortisol were measured by radioimmunoassay and protein binding techniques respectively in plasma from blood taken at 20-min intervals over 24-h periods in 3 normal men, 2 women with Stein-Leventhal syndrome, and a man with a benign adrenocortical adenoma. In all subjects but the latter, DHA and cortisol were episodic and synchronous throughout the entire day; in this patient, continuous secretion of cortisol by the tumor apparently abolished stimulation of the contralateral adrenal, and DHA production was negligible. Dehydroisoandrosterone sulfate analyses in plasma displayed a pattern which, probably because of its origin both by secretion and sulfation and its long half-life, showed less synchronicity with DHA and cortisol and less fluctuation than did the free hormones.

  9. Boiling points of halogenated aliphatic compounds: a quantitative structure-property relationship for prediction and validation.

    Science.gov (United States)

    Oberg, Tomas

    2004-01-01

    Halogenated aliphatic compounds have many technical uses, but substances within this group are also ubiquitous environmental pollutants that can affect the ozone layer and contribute to global warming. The establishment of quantitative structure-property relationships is of interest not only to fill in gaps in the available database but also to validate experimental data already acquired. The three-dimensional structures of 240 compounds were modeled with molecular mechanics prior to the generation of empirical descriptors. Two bilinear projection methods, principal component analysis (PCA) and partial-least-squares regression (PLSR), were used to identify outliers. PLSR was subsequently used to build a multivariate calibration model by extracting the latent variables that describe most of the covariation between the molecular structure and the boiling point. Boiling points were also estimated with an extension of the group contribution method of Stein and Brown.

  10. Evaluation and treatment of hypertensive crises in children

    Directory of Open Access Journals (Sweden)

    Stein DR

    2016-03-01

    Full Text Available Deborah R Stein, Michael A Ferguson Division of Nephrology, Boston Children's Hospital, Harvard Medical School, Boston, MA, USA Abstract: Hypertensive crises in children are medical emergencies that must be identified, evaluated, and treated promptly and appropriately to prevent end-organ injury and even death. Treatment in the acute setting typically includes continuous intravenous antihypertensive medications with monitoring in the intensive care unit setting. Medications commonly used to treat severe hypertension have been poorly studied in children. Dosing guidelines are available, although few pediatric-specific trials have been conducted to facilitate evidence-based therapy. Regardless of what medication is used, blood pressure should be lowered gradually to allow for accommodation of autoregulatory mechanisms and to prevent cerebral ischemia. Determining the underlying cause of the blood pressure elevation may be helpful in guiding therapy.

The results identify that the respondents have very similar approaches regarding affective, instrumental and normative commitment perceptions. Still, it was noticed that the highest means for both generations, were obtained in the construct of affective commitment. The clearest difference emerged in the focus of instrumental commitment, which determines the individual’s need to remain in business.

    The objective of this editorial is to show that a harmonious relationship between science and faith is possible, as exemplified by great saints of the Catholic Church. It begins with the definitions of science and faith, followed by an explanation of the apparent conflict between them. A few saints that constitute an example that a fruitful relationship between these two seemingly opposed realities has been possible are Saint Albert the Great, Saint John of the Cross, Saint Giuseppe Moscati, and Saint Edith Stein, among others, and this editorial highlights their deep contributions to the dialogue between faith and reason. This editorial ends with a brief discussion on whether it is possible to be both a scientist and a man of faith.

  13. Stanovich's arguments against the "adaptive rationality" project: An assessment.

    Polonioli, Andrea

    2015-02-01

    This paper discusses Stanovich's appeal to individual differences in reasoning and decision-making to undermine the "adaptive rationality" project put forth by Gigerenzer and his co-workers. I discuss two different arguments based on Stanovich's research. First, heterogeneity in the use of heuristics seems to be at odds with the adaptationist background of the project. Second, the existence of correlations between cognitive ability and susceptibility to cognitive bias suggests that the "standard picture of rationality" (Stein, 1996, 4) is normatively adequate. I argue that, as matters stand, none of the arguments can be seen as fully compelling. Nevertheless, my discussion is not only critical of Stanovich's research, as I also show that (and how) his research can push forward the so-called "rationality debate" by encouraging greater theoretical and experimental work.

    Endometrial carcinoma usually occurs in postmenopausal women ; less than 5% occurs in women under the age of 40. Up to one quarter of endometrial carcinoma patients below this age have PCO(polycystic ovary disease, Stein-Leventhal syndrome). The increased incidence of endometrial carcinoma in patients with PCO is related to chronic estrogenic stimulation. We report MR imaging in one case of endometrial carcinoma occuring in a 23 year old woman with PCO and had complained of hypermenorrhea for about three years. On T2-weighted MR image the endometrial cavity was seen to be distended with protruded endometrial masses of intermediate signal intensity, and the junctional zone was disrupted beneath the masses. Both ovaries were best seen on T2-weighted MR imaging and showed multiple small peripheral cysts and low signal-intensity central stroma.

  15. Triviality of the ground-state metastate in long-range Ising spin glasses in one dimension

    Read, N.

    2018-01-01

    We consider the one-dimensional model of a spin glass with independent Gaussian-distributed random interactions, which have mean zero and variance 1/|i -j | 2 σ, between the spins at sites i and j for all i ≠j . It is known that, for σ >1 , there is no phase transition at any nonzero temperature in this model. We prove rigorously that, for σ >3 /2 , any translation-covariant Newman-Stein metastate for the ground states (i.e., the frequencies with which distinct ground states are observed in finite-size samples in the limit of infinite size, for given disorder) is trivial and unique. In other words, for given disorder and asymptotically at large sizes, the same ground state, or its global spin flip, is obtained (almost) always. The proof consists of two parts: One is a theorem (based on one by Newman and Stein for short-range two-dimensional models), valid for all σ >1 , that establishes triviality under a convergence hypothesis on something similar to the energies of domain walls and the other (based on older results for the one-dimensional model) establishes that the hypothesis is true for σ >3 /2 . In addition, we derive heuristic scaling arguments and rigorous exponent inequalities which tend to support the validity of the hypothesis under broader conditions. The constructions of various metastates are extended to all values σ >1 /2 . Triviality of the metastate in bond-diluted power-law models for σ >1 is proved directly.

The presence of the competitive inhibition state has been known to science for many years, but from a functional standpoint it has been noted in the literature as being "meaningless."Methods: A large database of monoamine transporter response to amino acid precursor administration variations with clinical outcomes was accumulated. In the process, a new organic cation transporter (OCT model has been published, and OCT functional status determination along with amino acid precursor manipulation methods have been invented and refined.Results: Methodology was developed whereby manipulation of the OCT, in the competitive inhibition state, is carried out in a predictable manner. This, in turn, has disproved the long-held assertion that the monoamine competitive inhibition state is functionally meaningless.Conclusion: The most significant aspect of this paper is the documentation of newly recognized relationships between serotonin and dopamine. When transport of serotonin and dopamine are both in the competitive inhibition state, manipulation of the concentrations of one will lead to predictable changes in concentrations of the other. From a functional standpoint, processes regulated and controlled by changes to only serotonin can now be controlled by changes to dopamine, and vice versa, in a predictable manner.Keywords: catecholamine, monoamine, competitive inhibition state

    The NSF-funded CINEMA mission will provide cutting-edge magnetospheric science and critical space weather measurements, including high sensitivity mapping and high cadence movies of ring current, >4 keV Energetic Neutral Atom (ENA), as well as in situ measurements of suprathermal electrons (>~2 keV) and ions (>~ 4 keV) in the auroral and ring current precipitation regions, all with ~1 keV FWHM resolution and uniform response up to ~100 keV. A Suprathermal Electron, Ion, Neutral (STEIN) instrument adds an electrostatic deflection system to the STEREO STE (SupraThermal Electron) 4-pixel silicon semiconductor sensor to separate ions from electrons and from ENAs up to ~20 keV. In addition, inboard and outboard (on an extendable 1m boom) magnetoresistive sensor magnetometers will provide high cadence 3-axis magnetic field measurements. A new attitude control system (ACS) uses torque coils, a solar aspect sensor and the magnetometers to de-tumble the 3u CINEMA spacecraft, then spin it up to ~1 rpm with the spin axis perpendicular to the ecliptic, so STEIN can sweep across most of the sky every minute. Ideally, CINEMA will be placed into a high inclination low earth orbit that crosses the auroral zone and cusp. An S-band transmitter will be used to provide > ~8 kbps orbit-average data downlink to the ~11m diameter antenna of the Berkeley Ground Station. Two more identical CINEMA spacecraft will be built by Kyung Hee University (KHU) in Korea under their World Class University (WCU) program, to provide stereo ENA imaging and multi-point in situ measurements. Furthermore, CINEMA’s development of miniature particle and magnetic field sensors, and cubesat-size spinning spacecraft will be important for future nanosatellite space missions.

This writing outlines a model explaining the origin of the three-phase response of urinary serotonin and dopamine. A “dual-gate lumen transporter model” for the basolateral monoamine transporters of the kidneys is proposed as being the etiology of the three-phase urinary serotonin and dopamine responses.Purpose: The purpose of this writing is to document the internal renal function model that has evolved in research during large-scale assay with phase interpretation of urinary serotonin and dopamine.Patients and methods: In excess of 75,000 urinary monoamine assays from more than 7,500 patients were analyzed. The serotonin and the dopamine phase were determined for specimens submitted in the competitive inhibition state. The phase determination findings were then correlated with peer-reviewed literature.Results: The correlation between the three-phase response of urinary serotonin and dopamine with internal renal processes of the bilateral monoamine transporter and the apical monoamine transporter of the proximal convoluted renal tubule cells is defined.Conclusion: The phase of urinary serotonin and dopamine is dependent on the status of the serotonin gate, dopamine gate, and lumen of the basolateral monoamine transporter while in the competitive inhibition state.Keywords: serotonin, dopamine, basolateral, apical, kidney, proximal

  20. Adult Fanniidae associated to pig carcasses during the winter season in a semiarid environment: initial examination of their potential as complementary PMI indicators.

    Besides the dominant necrophagous dipteran of the families Sarcophagidae and Calliphoridae usually used for post mortem interval (PMI) estimations, species of other families such as Fanniidae have frequently been reported in forensic studies. Though less abundant, these species are prevalent in decomposing carcasses with most reports being anecdotal. In this study we identified adults of the fly family Fanniidae associated to pig carcasses located under different local environmental conditions (sun and shade) in a semiarid area at Mendoza, Argentina during the winter season. We examined the potential of species of this family as indicators of PMI by measuring abundance, time of occurrence and residency time at the carcasses. We identified six species of Fanniidae: Euryomma peregrinum Meigen, Fannia albitarsis Stein, Fannia femoralis Stein, Fannia fusconotata Rondani, Fannia heydenii Wiedemann and Fannia sanihue Domínguez and Aballay. Overall, fly abundance was higher at the sunlit than at the shaded carcass. The most abundant species at the sun was F. fusconotata while at the shaded carcass F. femoralis was the most abundant species. Based on their residency time, however, species with higher potential as PMI indicators seem to be F. heydenii and F. sanihue as their residency time at the carcass was restricted to a short period of the decomposition process. Other species were present throughout most of the decomposition process or in such a low abundance (E. peregrinum) that they were not useful as indicators. These preliminary results indicate that adults of some species of Fanniidae could act as a good complementary indicator species during the winter season. In particular, F. heydenii and F. sanihue should be the focus of further studies which should also expand to other seasons. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

  1. Coupling Satellite Data with Species Distribution and Connectivity Models as a Tool for Environmental Management and Planning in Matrix-Sensitive Species

    Climate change and anthropogenic habitat fragmentation are considered major threats for global biodiversity. As a direct consequence, connectivity is increasingly disrupted in many species, which might have serious consequences that could ultimately lead to the extinction of populations. Although a large number of reserves and conservation sites are designated and protected by law, potential habitats acting as inter-population connectivity corridors are, however, mostly ignored in the common practice of environmental planning. In most cases, this is mainly caused by a lack of quantitative measures of functional connectivity available for the planning process. In this study, we highlight the use of fine-scale potential connectivity models (PCMs) derived from multispectral satellite data for the quantification of spatially explicit habitat corridors for matrix-sensitive species of conservation concern. This framework couples a species distribution model with a connectivity model in a two-step framework, where suitability maps from step 1 are transformed into maps of landscape resistance in step 2 filtered by fragmentation thresholds. We illustrate the approach using the sand lizard ( Lacerta agilis L.) in the metropolitan area of Cologne, Germany, as a case study. Our model proved to be well suited to identify connected as well as completely isolated populations within the study area. Furthermore, due to its fine resolution, the PCM was also able to detect small linear structures known to be important for sand lizards' inter-population connectivity such as railroad embankments. We discuss the applicability and possible implementation of PCMs to overcome shortcomings in the common practice of environmental impact assessments.

    Whether or not animals habituate to repeated exposure to predator scents may depend upon whether there are predators associated with the cues. Understanding the contexts of habituation is theoretically important and has profound implication for the application of predator-based herbivore deterrents. We repeatedly exposed a mixed mob of macropod marsupials to olfactory scents (urine, feces) from a sympatric predator (Canis lupus dingo), along with a control (water). If these predator cues were alarming, we expected that over time, some red kangaroos (Macropus rufous), western grey kangaroos (Macropus fuliginosus) and agile wallabies (Macropus agilis) would elect to not participate in cafeteria trials because the scents provided information about the riskiness of the area. We evaluated the effects of urine and feces independently and expected that urine would elicit a stronger reaction because it contains a broader class of infochemicals (pheromones, kairomones). Finally, we scored non-invasive indicators (flight and alarm stomps) to determine whether fear or altered palatability was responsible for the response. Repeated exposure reduced macropodid foraging on food associated with 40 ml of dingo urine, X = 986.75+/-3.97 g food remained as compared to the tap water control, X = 209.0+/-107.0 g (P0.5). Macropodids did not habituate to repeated exposure to predator scents, rather they avoided the entire experimental area after 10 days of trials (R(2) = 83.8; P<0.001). Responses to urine and feces were indistinguishable; both elicited fear-based responses and deterred foraging. Despite repeated exposure to predator-related cues in the absence of a predator, macropodids persistently avoided an area of highly palatable food. Area avoidance is consistent with that observed from other species following repeated anti-predator conditioning, However, this is the first time this response has been experimentally observed among medium or large vertebrates - where a local response

    Infection with hepatitis B virus (HBV) has been detected in human populations throughout the world, as well as in a number of ape species (Pan troglodytes, Gorilla gorilla, gibbons [Nomascus and Hylobates species] and Pongo pygmaeus). To investigate the distribution of naturally occurring HBV infection in these species and other African Old World monkey species (Cercopithecidae), we screened 137 plasma samples from mainly wild caught animals by polymerase chain reaction (PCR) using several of highly conserved primers from the HB surface (HBs) gene, and for HBs antigen (HBsAg) by ELISA. None of the 93 Cercopithecidae screened (6 species) showed PCR or serology evidence for HBV infection; in contrast 2 from 8 chimpanzees and 5 from 22 gibbons were PCR-positive with each set of primers. Complete genome sequences from each of the positive apes were obtained and compared with all previously published complete and surface gene sequences. This extended phylogenetic analysis indicated that HBV variants from orangutans were interspersed by with HBV variants from southerly distributed gibbon species (H. agilis and H. moloch) occupying overlapping or adjacent habitat ranges with orangutans; in contrast, HBV variants from gibbon species in mainland Asia were phylogenetically distinct. A geographical rather than (sub)species association of HBV would account for the distribution of HBV variants in different subspecies of chimpanzees in Africa, and explain the inlier position of the previously described lowland gorilla sequence in the chimpanzee clade. These new findings have a number of implication for understanding the origins and epidemiology of HBV infection in non-human primates

    Hepatozoon parasites comprise intracellular apicomplexan parasites transmitted to vertebrate animals by ingestion of arthropods definitive hosts. The present work aimed to investigate the occurrence of Hepatozoon spp. in wild animals, domestic dogs and their respective ectoparasites, in southern Pantanal region, central-western Brazil, by molecular techniques. Between August 2013 and March 2015, 31 coatis (Nasua nasua), 78 crab-eating foxes (Cerdocyon thous), seven ocelots (Leopardus pardalis), 42 dogs (Canis lupus familiaris), 110 wild rodents (77 Thichomys fosteri, 25 Oecomys mamorae, and 8 Clyomys laticeps), 30 marsupials (14 Thylamys macrurus, 11 Gracilinanus agilis, 4 Monodelphis domestica and 1 Didelphis albiventris), and 1582 ticks and 80 fleas collected from the sampled animals were investigated. DNA samples were submitted to PCR assays for Hepatozoon spp. targeting 18S rRNA gene. Purified amplicons were directly sequenced and submitted to phylogenetic analysis. A high prevalence of Hepatozoon among carnivores (C. thous [91.02%], dogs [45.23%], N. nasua [41.9%] and L. pardalis [71.4%]) was found. However, ticks and fleas were negative to Hepatozoon PCR assays. By phylogenetic analysis based on 18S rRNA sequences, Hepatozoon sequences amplified from crab-eating foxes, dogs, coatis and ocelots clustered with sequences of H. canis, H. americanum and H. felis. The closely related positioning of Hepatozoon sequences amplified from wild rodents and T. macrurus marsupial to Hepatozoon from reptiles and amphibians suggest a possible transmission of those Hepatozoon species between hosts by ectoparasites or by predation. Hepatozoon haplotypes found circulating in wild rodents seem to present a higher degree of polymorphism when compared to those found in other groups of animals. Although rodents seem not to participate as source of Hepatozoon infection to wild carnivores and domestic dogs, they may play an important role in the transmission of Hepatozoon to reptiles

  5. Human-specific SNP in obesity genes, adrenergic receptor beta2 (ADRB2, Beta3 (ADRB3, and PPAR γ2 (PPARG, during primate evolution.

    Directory of Open Access Journals (Sweden)

    Akiko Takenaka

    Full Text Available UNLABELLED: Adrenergic-receptor beta2 (ADRB2 and beta3 (ADRB3 are obesity genes that play a key role in the regulation of energy balance by increasing lipolysis and thermogenesis. The Glu27 allele in ADRB2 and the Arg64 allele in ADRB3 are associated with abdominal obesity and early onset of non-insulin-dependent diabetes mellitus (NIDDM in many ethnic groups. Peroxisome proliferator-activated receptor γ (PPARG is required for adipocyte differentiation. Pro12Ala mutation decreases PPARG activity and resistance to NIDDM. In humans, energy-expense alleles, Gln27 in ADRB2 and Trp64 in ADRB3, are at higher frequencies than Glu27 and Arg64, respectively, but Ala12 in PPARG is at lower frequency than Pro12. Adaptation of humans for lipolysis, thermogenesis, and reduction of fat accumulation could be considered by examining which alleles in these genes are dominant in non-human primates (NHP. All NHP (P. troglodytes, G. gorilla, P. pygmaeus, H. agilis and macaques had energy-thrifty alleles, Gly16 and Glu27 in ADRB2, and Arg64 in ADRB3, but did not have energy-expense alleles, Arg16, Gln27 and Trp64 alleles. In PPARG gene, all NHP had large adipocyte accumulating type, the Pro12 allele. CONCLUSIONS: These results indicate that a tendency to produce much more heat through the energy-expense alleles developed only in humans, who left tropical rainforests for savanna and developed new features in their heat-regulation systems, such as reduction of body hair and increased evaporation of water, and might have helped the protection of entrails from cold at night, especially in glacial periods.

  6. Status and conservation of parrots and parakeets in the Greater Antilles, Bahama Islands, and Cayman Islands

    In the 1490s a minimum of 28 species of psittacines occurred in the West Indies. Today, only 43% (12) of the species survive. All macaws and most parakeet species have been lost. Although the surviving parrot fauna of the Greater Antilles, Cayman Islands, and Bahama Islands has fared somewhat better than that of the Lesser Antilles, every species has undergone extensive reductions of populations and all but two have undergone extensive reductions in range, mostly as a result of habitat loss, but also from persecution as agricultural pests, conflicts with exotic species, harvesting for pets, and natural disasters. The Cayman Brac Parrot Amazona leucocephala hesterna with its tiny population (less than 150 individuals in the wild) and range, and the Puerto Rican Parrot A. vittata, with about 22-23 birds in the wild and 56 individuals in captivity, must be considered on the verge of extinction and in need of (in the latter's case, continuing) aggressive programmes of research and management. Other populations declining in numbers and range include the Yellow-billed Amazona collaria, and Black-billed A. agilis Parrots of Jamaica, Hispaniolan Parakeet Aratinga chloroptera, Hispaniolan Parrot Amazona ventralis, Cuban Parrot A. leucocephala leucocephala and, most seriously, Cuban Parakeet Aratinga euops. The population of the Grand Cayman Parrot (Amazona leucocephala caymanensis), although numbering only about 1,000 birds, appears stable and the current conservation programme gives hope for the survival of the race. An active conservation and public education programme has begun for the Bahama Parrot A. l. bahamensis, which still occurs in good numbers on Great Inagua Island, but is threatened on Abaco Island. Recommendations for conservation of parrots and parakeets in the region include (1) instituting long-term programmes of research to determine distribution, status, and ecology of each species; (2) developing conservation programmes through education and management

    Greece represents an important area for wild birds due to its geographical position and habitat diversity. Although the bird species in Greece are well recorded, the information about the chewing lice that infest them is practically non-existent. Thus, the aim of the present study was to record the species of lice infesting wild birds in northern Greece and furthermore, to associate the infestation prevalence with factors such as the age, sex, migration and social behaviour of the host as well as the time of the year. In total 729 birds, (belonging to 9 orders, 32 families and 68 species) were examined in 7 localities of northern Greece, during 9 ringing sessions from June 2013 until October 2015. Eighty (11%) of the birds were found to be infested with lice. In 31 different bird species, 560 specimens of lice, belonging to 33 species were recorded. Mixed infestations were recorded in 11 cases where birds were infested with 2-3 different lice species. Four new host-parasite associations were recorded i.e. Menacanthus curuccae from Acrocephalus melanopogon, Menacanthus agilis from Cettia cetti, Myrsidea sp. from Acrocephalus schoenobaenus, and Philopretus citrinellae from Spinus spinus. Moreover, Menacanthus sinuatus was detected on Poecile lugubris, rendering this report the first record of louse infestation in this bird species. The statistical analysis of the data collected showed no association between parasitological parameters (prevalence, mean and median intensity and mean abundance) in two different periods of the year (breeding vs post-breeding season). However, there was a statistically significant difference in the prevalence of infestation between a) migrating and sedentary passerine birds (7.4% vs 13.2%), b) colonial and territorial birds (54.5% vs 9.6%), and c) female and male birds in breeding period (2.6% vs 15.6%).

    The success of ectoparasites depends primarily on the site of attachment and body condition of their hosts. Ticks usually tend to aggregate on vertebrate hosts in specific areas, but the distribution pattern may depend on host body size and condition, sex, life stage or skin morphology. Here, we studied the distribution of ticks on lizards and tested the following hypothesis: occurrence or high abundance of ticks is confined with body parts with smaller scales and larger interscalar length because such sites should provide ticks with superior attachment conditions. This study was performed in field conditions in central Poland in 2008-2011. In total, 500 lizards (Lacerta agilis) were caught and 839 ticks (Ixodes ricinus, larvae and nymphs) were collected from them. Using generalised linear mixed models, we found that the ticks were most abundant on forelimbs and their axillae, with 90% of ticks attached there. This part of the lizard body and the region behind the hindlimb were covered by the smallest scales with relatively wide gaps between them. This does not fully support our hypothesis that ticks prefer locations with easy access to skin between scales, because it does not explain why so few ticks were in the hindlimb area. We found that the abundance of ticks was positively correlated with lizard body size index (snout-vent length). Tick abundance was also higher in male and mature lizards than in female and young individuals. Autotomy had no effect on tick abundance. We found no correlation between tick size and lizard morphology, sex, autotomy and body size index. The probability of occurrence of dead ticks was positively linked with the total number of ticks on the lizard but there was no relationship between dead tick presence and lizard size, sex or age. Thus lizard body size and sex are the major factors affecting the abundance of ticks, and these parasites are distributed nearly exclusively on the host's forelimbs and their axillae.

    Telomere length is restored primarily through the action of the reverse transcriptase telomerase, which may contribute to a prolonged lifespan in some but not all species and may result in longer telomeres in one sex than the other. To what extent this is an effect of proximate mechanisms (e.g. higher stress in males, higher oestradiol/oestrogen levels in females), or is an evolved adaptation (stronger selection for telomere length in one sex), usually remains unknown. Sand lizard (Lacerta agilis) females have longer telomeres than males and better maintain telomere length through life than males do. We also show that telomere length more strongly contributes to life span and lifetime reproductive success in females than males and that telomere length is under sexually diversifying selection in the wild. Finally, we performed a selection analysis with number of recruited offspring into the adult population as a response variable with telomere length, life span and body size as predictor variables. This showed significant differences in selection pressures between the sexes with strong ongoing selection in females, with these three predictors explaining 63% of the variation in recruitment. Thus, the sexually dimorphic telomere dynamics with longer telomeres in females is a result of past and ongoing selection in sand lizards. Finally, we compared the results from our selection analyses based on Telometric-derived data to the results based on data generated by the software ImageJ. ImageJ resulted in shorter average telomere length, but this difference had virtually no qualitative effect on the patterns of ongoing selection. © 2011 Blackwell Publishing Ltd.

    The reflectance of a planetary surface as measured at different phase angles can provide useful information about several properties, both optical (importance of multiple and single scattering, regolith shadowing) and physical (roughness and regolith grain size). In particular, disk-resolved observations allow one to monitor photometric properties variations across a planetary surface. In this work, we retrieved disk-resolved phase functions of asteroids Vesta and Lutetia, by means of hyperspectral images returned by the Visible and InfraRed (VIR) mapping spectrometer onboard NASA's Dawn spacecraft, and the Visible, InfraRed, and Thermal Imaging Spectrometer (VIRTIS), onboard ESA's Rosetta spacecraft, respectively. Then we compared their photometric properties with those obtained of other asteroids closely explored by space missions (Gaspra, Ida, Eros, Annefrank, Steins, Mathilde). The trend of reflectance as a function of phase angle has been obtained by undertaking a statistical analysis, based on the empirical definition of reflectance families. For each family, the relation between reflectance and phase has been then calculated. On Vesta, we find steeper phase functions in dark material units, which become flatter with increasing albedo. This has been ascribed to a relevant role of multiple scattering in bright regions. As opposed to Vesta, Lutetia is a more homogeneous body. Hence we can consider a unique phase function for the whole asteroid surface. We chose two parameters useful to describe the photometric behavior of these asteroids: the reflectance which would be observed at a 30° phase, tagged R30, and the ''phase slope'' or the reflectance percent decrease between 20° and 60° phase, tagged PS. These two parameters have been calculated also on disk-resolved phase functions of other asteroids available in literature. We find that all S-type asteroids place in the same region of the R30-PS scatterplot, due to their similar photometric properties. C

    Geostatistical-based image/surface texture indices based on variogram (Atkison and Lewis, 2000; Herzfeld and Higginson, 1996; Trevisani et al., 2012) and on its robust variant MAD (median absolute differences, Trevisani and Rocca, 2015) offer powerful tools for the analysis and interpretation of surface morphology (potentially not limited to solid earth). In particular, the proposed robust index (Trevisani and Rocca, 2015) with its implementation based on local kernels permits the derivation of a wide set of robust and customizable geomorphometric indices capable to outline specific aspects of surface texture. The stability of MAD in presence of signal noise and abrupt changes in spatial variability is well suited for the analysis of high-resolution digital terrain models. Moreover, the implementation of MAD by means of a pixel-centered perspective based on local kernels, with some analogies to the local binary pattern approach (Lucieer and Stein, 2005; Ojala et al., 2002), permits to create custom roughness indices capable to outline different aspects of surface roughness (Grohmann et al., 2011; Smith, 2015). In the proposed poster, some potentialities of the new indices in the context of geomorphometry and landscape analysis will be presented.

    Full Text Available Marty Hinz,1 Alvin Stein,2 Ted Cole3 1Clinical Research, NeuroResearch Clinics, Inc., Cape Coral, FL, USA; 2Stein Orthopedic Associates, Plantation, FL, USA; 3Cole Center for Healing, Cincinnati, OH, USA Abstract: The amino acid L-3,4-dihydroxyphenylalanine (L-dopa is prescribed for conditions where increased central and/or peripheral dopamine synthesis is desired. Its administration can establish dopamine concentrations higher than can be achieved from an optimal diet. Specific indications include Parkinson's disease and restless leg syndrome. The interaction between serotonin and dopamine exists in one of two distinctly different physiologic states: the endogenous state or the competitive inhibition state. Management with L-dopa in the competitive inhibition state is the focus of this paper. In the past, control of the competitive inhibition state was thought to be so difficult and complex that it was described in the literature as functionally “meaningless”. When administering L-dopa without simultaneous administration of serotonin precursors, the patient is in the endogenous state. Experience gained with patient outcomes during endogenous L-dopa administration does not allow predictability of L-dopa outcomes in the competitive inhibition state. The endogenous approach typically increases the daily L-dopa dosing value in a linear fashion until symptoms of Parkinson's disease are under control. It is the novel observations made during treatment with the competitive inhibition state approach that L-dopa dosing values above or below the optimal therapeutic range are generally associated with the presence of the exact same Parkinson's disease symptoms with identical intensity. This recognition requires a novel approach to optimization of daily L-dopa dosing values from that used in the endogenous state. This paper outlines that novel approach through utilization of a pill stop. This approach enhances patient safety through its ability to

    For the Lorentz group G = SO/sub e/(n + 1, 1)(ngreater than or equal to 2) the author constructs a family of uniformly bounded representations by means of analytically continuing a certain normalization of the unitary principal series. The method the author uses relies on an analysis of various operators under a Mellin transform and extends earlier work of E.N. Wilson. In a series of papers Kunze and Stein initiated the theory of uniformly bounded representations of semisimple Lie groups; the starting point is the unitary principal series T(sigma,s) obtained in a certain subgroup M of G and a purely imaginary number s. From there Kunze and Stein constructed families of representations R(sigma,s) depending analytically on a parameter s in a domain D of C containing the imaginary axis which are unitarily equilvalent to T(sigma,s) for s contained in the set of imaginary numbers and whose operator norms are uniformly bounded for each s in D. In the case of the Lorentz groups SO/sub e/(n + 1, 1)(ngreater than or equal to2) and the trivial representation 1 of M, E.N. Wilson obtained such a family R(1,s) for the domain D = [s contained in the set of C: absolute value Re(s) Vertical Bar2]. For this domain D and for any representation sigma of M the author provides a family R(sigma,s) of uniformly bounded representations analytically continuing T(sigma,s), thereby generalizing Wilson's work. The author has also investigated certain symmetry properties of the representations R(sigma,s) under the action of the Weyl group. The trivial representation is Weyl group invariant and the family R(1,s) obtained by Wilson satisfies R(1,s) = R(1,-s) reflecting this. Obtained was the analogous result R(sigma,s) = R(sigma,-s) for some well known representations sigma that are Weyl group invariant. This involves the explicit computation of certain constants arising in the Fourier transforms of intertwining operators

The goal of this research was to document the findings and related considerations of a retrospective chart review study designed to identify issues and areas of concern that will define parameters for a prospective controlled study.Methods: This study included 85 patients, aged 4–18 years, who were treated with a novel amino acid precursor protocol. Their clinical course during the first 8–10 weeks of treatment was analyzed retrospectively. The study team consisted of PhD clinical psychologists, individuals compiling clinical data from records, and a statistician. The patients had been treated with a predefined protocol for administering amino acid precursors of serotonin and dopamine, along with OCT assay interpretation as indicated.Results: In total, 67% of participants achieved significant improvement with only amino acid precursors of serotonin and dopamine. In patients who achieved no significant relief of symptoms with only amino acid precursors, OCT assay interpretation was utilized. In this subgroup, 30.3% achieved significant relief following two or three urine assays and dosage changes as recommended by the assay results. The total percentage of patients showing significant improvement was 77%.Conclusion: The efficacy of this novel protocol appears superior to some ADHD prescription drugs

    Full Text Available Marty Hinz1, Alvin Stein2, Thomas Uncini31Clinical Research, NeuroResearch Clinics Inc, Cape Coral, FL; 2Stein Orthopedic Associates, Plantation, FL; 3DBS Labs Inc, Duluth, MN, USABackground: Disagreement exists regarding the etiology of cessation of the observed clinical results with administration of reuptake inhibitors. Traditionally, when drug effects wane, it is known as tachyphylaxis. With reuptake inhibitors, the placebo effect is significantly greater than the drug effect in the treatment of depression and attention deficit hyperactivity disorder, leading some to assert that waning of drug effects is placebo relapse, not tachyphylaxis.Methods: Two groups were retrospectively evaluated. Group 1 was composed of subjects with depression and Group 2 was composed of bariatric subjects treated with reuptake inhibitors for appetite suppression.Results: In Group 1, 200 subjects with depression were treated with citalopram 20 mg per day. A total of 46.5% (n = 93 achieved relief of symptoms (Hamilton-D rating score ≤ 7, of whom 37 (39.8% of whom experienced recurrence of depression symptoms, at which point an amino acid precursor formula was started. Within 1–5 days, 97.3% (n = 36 experienced relief of depression symptoms. In Group 2, 220 subjects were treated with phentermine 30 mg in the morning and citalopram 20 mg at 4 pm. In this group, 90.0% (n = 198 achieved adequate appetite suppression. The appetite suppression ceased in all 198 subjects within 4–48 days. Administration of an amino acid precursor formula restored appetite suppression in 98.5% (n = 195 of subjects within 1–5 days.Conclusion: Reuptake inhibitors do not increase the total number of monoamine molecules in the central nervous system. Their mechanism of action facilitates redistribution of monoamines from one place to another. In the process, conditions are induced that facilitate depletion of monoamines.

    The examination of surface sediment samples collected from 17 sites along the Lomonosov Ridge at water depths ranging from 737 to 3339 meters during Polarstern Expedition PS87 in 2014 (Stein, 2015), indicates a rich biogenic content almost exclusively dominated by calcareous remains. Amongst biogenic remains, microfossils (planktic and benthic foraminifers, pteropods, ostracods, etc.) dominate but millimetric to centrimetric macrofossils occurred frequently at the surface of the sediment. The macrofossil remains consist of a large variety of taxa, including gastropods, bivalvia, polychaete tubes, scaphopods, echinoderm plates and spines, and fish otoliths. Among the Bivalvia, the most abundant taxa are Portlandia arctica, Hyalopecten frigidus, Cuspidaria glacilis, Policordia densicostata, Bathyarca spp., and Yoldiella spp. Whereas a few specimens are well preserved and apparently pristine, most mollusk shells displayed extensive alteration features. Moreover, most shells were covered by millimeter scale tubes of the serpulid polychaete Spirorbis sp. suggesting transport from low intertidal or subtidal zone. Both the ecological affinity and known geographic distribution of identified bivalvia as named above support the hypothesis of transportation rather than local development. In addition to mollusk shells, more than a hundred fish otoliths were recovered in surface sediments. The otoliths mostly belong to the Gadidae family. Most of them are well preserved and without serpulid tubes attached to their surface, suggesting a local/regional origin, unlike the shell remains. Although recovered at the surface, the macrofaunal assemblages of the Lomonosov Ridge do not necessarily represent the "modern" environments as they may result from reworking and because their occurrence at the surface of the sediment may also be due to winnowing of finer particles. Although the shells were not dated, we suspect that their actual ages may range from modern to several thousands of

    In the Capbreton area, suprabenthic assemblages were sampled with a sledge towed over the bottom, at different sites located within the upper part of a 'gouf-type' canyon (8 hauls between 642 m and 797 m, on the axis of the thalweg or on flat perched flank terraces such as site K), on the northern adjacent open slope (2 hauls between 500 and 567 m) and on the northern adjacent shelf margin (2 hauls between 151 m and 158 m). A multivariate analysis carried on the faunal data discriminated different assemblages in this area: a near-canyon shelf assemblage (55 species, mainly amphipods and decapods; 3496 ind./100 m2, 40% mysids; dominant species: Nyctiphanes couchii, Leptomysis gracilis, Weswoodilla rectirostris, Anchialina agilis, Scopelocheirus hopei and Philocheras bispinosus); an open slope assemblage (111 species, mainly amphipods and isopods; 249 ind./100 m2, 36% amphipods; dominant species: Disconectes phalangium, Munnopsurus atlanticus and Boreomysis arctica); a canyon E assemblage (129 species, mainly amphipods, mysids and cumaceans; 1172 ind./100 m2, 58% amphipods; dominant species: Melphidippa sp. B, Chelator insignis); a canyon E' assemblage (107 species, mainly amphipods and mysids; 507 ind./100 m2, 73% amphipods; dominant species: Cleonardopsis carinata, Bonnierella abyssorum, Rhachotropis caeca and Arcturopsis giardi); and a temporary canyon assemblage at site K (34 species, mainly amphipods and mysids; 899 ind./100 m2, 85% amphipods; dominant species: Tmetomyx similis, Caeconyx caeculus, Nebalia sp. A and Cleonardopsis carinata). Site K was sampled only four months after a turbidity event, detected on sediment cores (18 cm thick Bouma sequence) taken during the same cruise and triggered by the violent storm ('ouragan Martin', wind up to 200 km/h) which affected the French Atlantic coast on 27 December 1999. The corresponding suprabenthic assemblage showed evidence of deep structural changes after this catastrophic event, characterized by relative low

    Full Text Available Human-induced effects on lowland conifer forests in hemiboreal regions are increasing because of expanded use of these northern ecosystems for raw materials, energy, and minerals as well as the potential effects of climatic changes. These forests support many breeding bird species across the Holarctic and allow the persistence of several boreal bird species in hemiboreal and even temperate regions. These bird species are of particular conservation concern as shifting patterns northward in forest composition caused by climate change will likely affect their populations. However, effective management and conservation options are limited because the specifics of these species' breeding habitats are not well understood. We modeled and mapped habitat suitability for 11 species of boreal birds that breed in the lowland conifer forests of the Agassiz Lowlands Ecological Subsection in northern Minnesota and are likely to have reduced breeding habitat in the future: Spruce Grouse (Falcipennis canadensis, Black-backed Woodpecker (Picoides arcticus, Olive-sided Flycatcher (Contopus cooperi, Yellow-bellied Flycatcher (Empidonax flaviventris, Boreal Chickadee (Poecile hudsonicus, Golden-crowned Kinglet (Regulus satrapa, Ruby-crowned Kinglet (Regulus calendula, Swainson's Thrush (Catharus ustulatus, Connecticut Warbler (Oporornis agilis, Palm Warbler (Setophaga palmarum, and Dark-eyed Junco (Junco hyemalis. Sets of 7 to 16 potential environmental covariates, including both stand-level and landscape attributes, were used to develop individual species models. Within this lowland conifer-dominated ecosystem, we found significant selection for specific forest and landscape characteristics by all but one of these species, with the best models including between one and nine variables. Habitat suitability maps were developed from these models and predictions tested with an independent dataset. Model performance depended on species, correctly predicting 56-96% of

    Twelve strains were isolated from different Egyptian juices. The nine bacteria strains were identified as Micrococcus agilis, Staphylococcus aureus, S. warneri, S. epidermidis, S. auricularls, Bacillus sp., Pseudomonas aeruginosa, Citrobacter frundii, and Streptococcus pedococcus while the yeast strains were Debaryomyces sp., Kluveromyces sp .and Pichia sp. Three of the previous strains were chosen in the present work according to their common contamination in all samples and their characteristics; S. aureus represented gram positive bacteria, P. aeruginosa represented gram negative bacteria and Debaryomyces sp. to represent yeast strains. S. aureus has completely annihilated by 250 μ g/ml. of nisin, or 0.2% citric acid, or 0.15% lactic acid, or 1.2 % cinnamon or 5 kGy of gamma rays.; P. aeruginosa was destroyed by 0.3 % citric acid, or 0.3 % lactic acid, or 4 % cinnamon or 4 kGy of gamma rays, while Debaryomyces sp. was eliminated by 4 % citric acid, or 4.5 % lactic acid, or 2 % cinnamon or 7 kGy of gamma rays. Nisin alone has no effect on P. aeruginosa or Debaryomyces sp. Combined treatments have decreased both of natural preservatives and irradiation doses needed to eliminate the microorganisms contaminated the juices. S. aureus was completely eliminated by 3 kGy combined with only 25 μ g/ml. of nisin. The lethal dose decreased to 2 kGy by combination with citric, lactic acid and cinnamon at conc. 0.05%, 0.01% and 0.4 %, respectively .The dose level of gamma rays needed to eliminate P. aeruginosa decreased to 3 kGy in combination with citric acid 0.1% or with cinnamon 0.5 % and it decreased to 2 kGy by combination with lactic acid 0.1 %. In case of Debaryomyces sp the lethal dose decreased from 7 kGy to 4 kGy by combination with citric acid 1.5 % or cinnamon 1 % and to 3 kGy with lactic acid 1.5 %. Also, the combination treatment has activated the effect of nisin on both of P. aeruginosa and Debaryomyces sp. Dose level of 4 kGy combined with 200 μ g/ml. nisin

    È ormai riconosciuto che bassa condizione socio-economica e limitato sviluppo culturale possono agire negativamente sul benessere individuale e sul livello di salute collettiva e determinano criticità nell’accesso alle cure, fenomeni che appaiono prevedibili, prevenibili e correggibili per migliorare la qualità e l’efficienza del sistema sanitario. Nell’area ferrarese sono presenti situazioni di svantaggio relativo non riconosciute e di difficile individuazione, il cui miglioramento si tradurrebbe in un beneficio sia per la condizione individuale che per la collettività.

    Obiettivi: la direzione sanitaria ed il Dipartimento di Sanità Pubblica dell’Azienda USL e l’Università degli Studi di Ferrara hanno dato vita al progetto “Osservatorio sulle disuguaglianze” allo scopo di sperimentare nuove modalità informative, più agili e tempestive delle rilevazioni censuarie, per individuare aree geografiche e/o fasce di popolazione verso le quali promuovere azioni di contrasto alle disuguaglianze in salute.

    Metodi: l’osservatorio prevede inizialmente tre sottoprogetti: 1. accesso agli screening femminili per definire i determinanti socio-ambientali e culturali delle donne non rispondenti; 2. salute neonati che, sulla base del nuovo certificato di assistenza al parto (CEDAP, mira a valutare situazioni di disuguaglianza in una fascia di età molto fragile; 3. coinvolgimento di medici di medicina generale (MMG, aderenti volontariamente all’indagine, nella raccolta sistematica di informazioni utili a monitorare il fenomeno delle disuguaglianze nella popolazione ferrarese. Risultati: l’attività dell’osservatorio è iniziata nell’aprile 2003 con l’elaborazione di un questionario da presentare alle donne non aderenti allo screening dei tumori del collo uterino e con la valutazione delle modalità di somministrazione del questionario (postale o telefonico avvalendosi della

    Floating net cage is one of the aquaculture practice operated in Indonesian coastal areas that has been growing rapidly over the last two decades. This study is aimed to assess the roles of macrobenthic mollusks as bioindicator in response to environmental disturbance caused by fish farming activities, and compare the samples within the locations using graphical methods. The research was done at the floating net cage fish farming area in the Awerange Gulf, South Sulawesi, Indonesia at the coordinates between 79°0500‧- 79°1500‧ LS and 953°1500‧- 953°2000‧ BT, at the polyculture and reference areas, which was located 1 km away from farming area. Sampling period was conducted between October 2014 to June 2015. The sediment samples were taken from the two locations with two sampling time and three replicates using Van Veen Grab for biotic and abiotic assessment. Mollusks as biotic parameter were fixed using 4% formalin solution and were preserved using 70% ethanol solution after 1mm mesh size. The macrobenthic mollusks were found as many as 15 species consisting of 14 families and 2 classes (gastropods and bivalves). Based on cumulative k-dominance analysis projected on each station, the line of station K3T1 (reference area; first sampling time) and KJAB P3T2 (polyculture area; second sampling time) are located below others curves, indicating the highest evenness and diversity compared to the other stations, whereas station K2T1 (reference area; first sampling time) and K3T2 (polyculture area, second sampling time) are located on the top, indicate the lowest value of evenness and diversity. Based on the bubble plots NMDS ordination, the four dominant taxa/species did not clearly show involvement in driving/shifting the ordinate position of station on the graph, except T. agilis. However, the two species showed involvement in driving/shifting the ordinate position of two stations of the reference areas from the first sampling time by Rynoclavis sordidula

(J.R.D.) It has been known for a hundred years that formaldehyde polymerizes to carbohydrate substances in alkaline media. Although the reaction has long attracted much attention, only recently has a detailed qualitative analysis of the products been carried out by chromatographic methods. We have started to re-examine this reaction by combining chromatography with radioactive tracer techniques in the hope of refining the quantitative aspects of the analysis. Our particular interest has been to develop methods for determining the relative proportions of ribose and ribulose in the mixtures of sugars formed in basic media, as well as under other polymerizing conditions. The finding of large amounts of these sugars might help to explain the occurrence of ribose as the only basic sugar in the fundamental replicating molecules--the nucleic acids. Formaldehyde is thought to have been present in the primitive reducing atmosphere which existed before life first appeared. The ribonucleic acids must have appeared in the constitution of reproducing systems at a very early stage in the development of living organisms. In this study, the polymerizations of formaldehyde

    Polycystic ovary syndrome (PCOS), also clinically known as Stein-Leventhal syndrome, is an endocrine disorder that affects 5-10% of women. To evaluate the risk factors for developing early onset of cardiovascular disease (CVD) in young patients with PCOS from our local population. Case-control study. Fifty women with PCOS selected by history and transvaginal ultrasounds and 30 age-matched healthy women (controls). The case subjects and controls were further divided into two age categories comprising of equal number of subjects, of 20-29 and 30-39 years of age. The subjects underwent a detailed medical history, general physical examination, systolic (SBP) and diastolic blood pressures (DBP). Fasting blood samples were analyzed for glucose, insulin, triacylglycerides (TAG), total cholesterol, high density lipoprotein-C (HDL-C), low density lipoprotein-C (LDL-C), follicle-stimulating hormone (FSH), and luteinizing hormone (LH). Women with the PCOS had significantly higher mean arterial pressure (MAP), serum TAG, LDL-C, insulin, and LH levels when compared with the age-matched control subjects. No significant differences were observed between serum cholesterol, glucose, and FSH levels between cases and controls. However, no marked differences were observed in biochemical parameters between the two age groups of PCOS patients. Younger women with PCOS are equally at risk of developing CVD as older women.

    During a period of 10 years (1977-1986) 40 cases of tumour of the pineal region have been treated at the Istituto Neurologico "C. Besta"-of Milan. Out of these 40 cases, 27 (67.5%) were in the paediatric (10-15 years) or juvenile (15-20 years) age at the time of operation. Since 1983 a specific diagnostic and therapeutic protocol has been adopted and thereafter direct surgical removal of the tumour was performed only when the neuroradiological investigations were highly suggestive of a benign extrinsic lesion. Sixteen cases in this series underwent direct surgical removal; in the remaining 24 cases stereotactic biopsy of the tumour was performed in the first instance. On the basis of the histological diagnosis obtained by this procedure surgical excision of the tumour (9 cases) or radiotherapy (15 cases) was then performed. 25 cases underwent surgical removal of the lesion. In all the cases the infratentorial supracerebellar approach as introduced by Krause and then modified by Stein was adopted. On analysis of the data of this series it was observed that in 25% of the cases completely benign resectable tumours were found; in 25% of the cases astrocytoma (grade I-II) which could be treated at least by partial removal were present; in 30% of the cases radiosensitive lesions were encountered. In the remaining 20% of the cases highly malignant tumours were found which should be treated only by radiotherapy and/or chemotherapy.

    The binucleate dinoflagellates Glenodinium (Peridinium) foliaceum Stein and Peridinium balticum (Levander) Lemmermann were found to contain two major buoyant density classes of DNA. The heavier peak (1.730 g/cm3) was derived from the "dinokaryotic" nucleus and the lighter peak (1.706 g/cm3) from the "endosymbiont" nucleus and this allowed for the fractionation of G. foliaceum DNA in CsCl/EtBr density gradients. An initial CsCl/Hoechst Dye gradient removed a minor A-T rich satellite species which was identified as plastid DNA with a size of about 100-106 kb. Analysis of the nuclear DNA by agarose gel electrophoresis and renaturation studies showed that the endosymbiont nucleus lacked amplified gene-sized DNA molecules, however, this nucleus did have a comparatively high level of DNA. The total amount of DNA per cell and the relative contributions of the two nuclei appeared to vary between two strains of G. foliaceum (75 pg/cell in CCAP strain and 58 pg in UTEX strain). The only strain of P. balticum examined contained 73 pg cell. These results are discussed in relation to the status and possible functioning of the endosymbiont nucleus and the idea that these dinoflagellates provide model systems with which to study the evolution of plastids.

  19. A hybrid spatial-spectral denoising method for infrared hyperspectral images using 2DPCA

    2016-11-01

    The traditional noise reduction methods for 3-D infrared hyperspectral images typically operate independently in either the spatial or spectral domain, and such methods overlook the relationship between the two domains. To address this issue, we propose a hybrid spatial-spectral method in this paper to link both domains. First, principal component analysis and bivariate wavelet shrinkage are performed in the 2-D spatial domain. Second, 2-D principal component analysis transformation is conducted in the 1-D spectral domain to separate the basic components from detail ones. The energy distribution of noise is unaffected by orthogonal transformation; therefore, the signal-to-noise ratio of each component is used as a criterion to determine whether a component should be protected from over-denoising or denoised with certain 1-D denoising methods. This study implements the 1-D wavelet shrinking threshold method based on Stein's unbiased risk estimator, and the quantitative results on publicly available datasets demonstrate that our method can improve denoising performance more effectively than other state-of-the-art methods can.

    Full Text Available In 1935, Stein and Leventhal first described the polycystic ovary (PCO as a frequent cause of irregular ovulation in women seeking treatment for subfertility. Although the initial management was surgical with wedge resection of ovary, the availability of radioimmunoassay and increased clinical use of ultrasound made it clear that many women had the ultrasound characteristics of PCO with or without the biochemical or clinical features of PCOS and therefore that PCO were not associated with a single syndrome. The association between increased insulin resistance and PCOS is a consistent finding in all ethnic groups. Obesity is a common factor in the majority of women with PCOS. It is postulated that a woman may be genetically predisposed to developing PCOS but it is only the interaction of environmental factors (obesity with the genetic factors that results in the characteristic metabolic and menstrual disturbances. Weight loss, altered diet and exercise have been shown to be effective in the management of PCOS. Importance of early recognition, proper intervention, long-term monitoring and health implications needs more concern.

    Facial paralysis has been a recognized condition since Antiquity, and was mentionned by Hippocratus. In the 17th century, in 1687, the Dutch physician Stalpart Van der Wiel rendered a detailed observation. It was, however, Charles Bell who, in 1821, provided the description that specified the role of the facial nerve. Facial nerve surgery began at the end of the 19th century. Three different techniques were used successively: nerve anastomosis, (XI-VII Balance 1895, XII-VII, Korte 1903), myoplasties (Lexer 1908), and suspensions (Stein 1913). Bunnell successfully accomplished the first direct facial nerve repair in the temporal bone, in 1927, and in 1932 Balance and Duel experimented with nerve grafts. Thanks to progress in microsurgical techniques, the first faciofacial anastomosis was realized in 1970 (Smith, Scaramella), and an account of the first microneurovascular muscle transfer published in 1976 by Harii. Treatment of the eyelid paralysis was at the origin of numerous operations beginning in the 1960s; including palpebral spring (Morel Fatio 1962) silicone sling (Arion 1972), upperlid loading with gold plate (Illig 1968), magnets (Muhlbauer 1973) and transfacial nerve grafts (Anderl 1973). By the end of the 20th century, surgeons had at their disposal a wide range of valid techniques for facial nerve surgery, including modernized versions of older techniques.

    2012-06-01

    Full Text Available Caught having an affair while employed at the home of the governor-general of Saigon, Vietnamese cook, migrant worker, and narrator of Monique Truong’s The Book of Salt, Binh, is cast out of his natal home, and sets off for the open sea, winding up as a live-in cook in the household of lesbian couple Gertrude Stein and Alice B. Toklas. As an abstract source of labor and culinary pleasure to those he encounters in Paris, Binh concludes, despondently, that he is, “nothing but a series of destinations with no meaningful expanses in between.” Yet the “expanses in between,” most notably in reference to waterways, allude to a central trope of Vietnamese culture. Incorporating Vietnamese symbolism with formative migratory experiences, this essay argues that Truong constructs a subject who can be read through both affective forms of national belonging as well as a broader queer diasporic community. It also explores Binh’s percipient tongue as one that is ever critical of the dynamics of power and privilege, and ever sensitive to the variances in salt (of sea, sweat, tears. The Book of Salt thus mediates the possibility of a gustatory epistemology and community constituted in the sensate, attuned to divergent experiences of mobility, labor, and love.

    To develop and assess the validity of an evaluation tool to assess quantitatively the hydrodissection and phacoemulsification portions of cataract surgery performed by residents. Case series. Jules Stein Eye Institute, Olive View-UCLA Medical Center, and Veterans Administration Medical Center, Los Angeles, California, USA. The UCLA ophthalmology faculty members were surveyed and the literature was reviewed to develop a grading tool consisting of 15 questions to evaluate surgical technique, including questions from the Global Rating Assessment of Skills in Intraocular Surgery and from the International Council of Ophthalmology's Ophthalmology Surgical Competency Assessment Rubric. Video clips of the hydrodissection and phacoemulsification portions of cataract surgery performed by 1 postgraduate year 2 (PGY2) resident, 1 PGY3 resident, 2 PGY4 residents, and an advanced surgeon were independently graded in a masked fashion by an 8-member faculty panel. Eleven of the 15 questions had a significant association with surgical experience level (Pinstrument handling, flow of operation, and nucleus rotation. Nucleus cracking also had low variability. Less directly visible tasks, especially 3-dimensional tasks, had wider interobserver variability. Surgical performance can be validly measured using an evaluation tool. Improved videography and studies to identify the best questions for evaluating each step of cataract surgery may help ophthalmic educators more precisely measure training outcomes for improving teaching interventions.

  4. Managing Disagreement: A Defense of "Regime Bias"

    Stein Ringen's theory of democratic purpose cannot do the work expected of it. Ringen's own criteria oscillate between being too vague to be useful (i.e. "freedom") or, when specified more fully, conflicting, so that almost all democracies will seem to be potentially at cross-purposes with themselves rather than their purposes or sub-purposes being mutually reinforcing. This reflects a bigger and more theoretical problem. Disagreement about the purpose of democracy is built into democracy itself. The whole point of many (perhaps all) of our democratic institutions is to arrive at conditionally legitimate decisions in spite of such disagreement. So-called regime bias, i.e. the tendency to assess democracies according to the form and stability of their institutions rather than their results or their ability to serve certain purposes, does not in fact arise from bias. It arises on the contrary from a determination to avoid the bias inherent in giving some-inevitably partisan-ideals of what democracies should do pride of place over others in a scheme of measurement or evaluation. And even a regime-based definition of democracy must itself make simplifying assumptions that elide possible normative controversies over how the democratic game is best played. Vindicating one's preferred set of democratic ideals against alternatives is a completely legitimate enterprise and lends richness to debates within and across democracies. But it is an inherently ideological and political enterprise, not a neutral or scholarly one.

  5. Mummy Lake: An unroofed ceremonial structure within a large-scale ritual landscape

    The structure at Mesa Verde National Park known historically as Mummy Lake and more recently as Far View Reservoir is not part of a water collection, impoundment, or redistribution system. We offer an alternative explanation for the function of Mummy Lake. We suggest that it is an unroofed ceremonial structure, and that it serves as an essential component of a Chacoan ritual landscape. A wide constructed avenue articulates Mummy Lake with Far View House and Pipe Shrine House. The avenue continues southward for approximately 6 km where it apparently divides connecting with Spruce Tree House and Sun Temple/Cliff Palace. The avenue has previously been interpreted as an irrigation ditch fed by water impounded at Mummy Lake; however, it conforms in every respect to alignments described as Chacoan roads. Tree-ring dates indicate that the construction of Spruce Tree House and Cliff Palace began about A.D. 1225, roughly coincident with the abandonment of the Far View community. This pattern of periodically relocating the focus of an Anasazi community by retiring existing ritual structures and linking them to newly constructed facilities by means of broad avenues was first documented by Fowler and Stein (1992) in Manuelito Canyon, New Mexico. Periods of intense drought appear to have contributed to the relocation of prehistoric Native Americans from the Far View group to Cliff Palace/Spruce Tree House in the mid-13th century and eventually to the abandonment of all Anasazi communities in southwestern Colorado in the late-13th century.

    Full Text Available The conservation and restoration of old stained manuscripts is an activity devoted to the preservation and protection of things of historical and personal significance made mainly from paper, parchment, and skin. We present in this paper a hybrid implementation for de-noising and restoration of old degraded and stained manuscripts. This implementation is based on the statistical dependence of the wavelet coefficients of type Ortho-normal Wavelet Thresholding Algorithm based on the principle of Stein’s Unbiased Risk-Estimate Linear Expansion of Thresholds (OWT SURE-LET and the synergy with bilateral filtering. First, the non-biased quadratic risk Stein estimator is applied to de-noise images corrupted by white Gaussian noise. In a second step, an improved bilateral filter is introduced to smooth and eliminate unnecessary details with the advantage of preserving edges between image regions. Obtained results show the effectiveness of the proposed synergy compared to separated approaches both on gray scale images and stained old manuscript.

    Our research was focused on the evaluation of bergenin content and free radical scavenging activity of extracts prepared from three different species of Bergenia - B. crassifolia (L.) Fritsch., B. ciliata (Haw.) Sternb. and B. x ornata Stein. collected during different seasons. Using an HPLC method, the highest total amount of bergenin was revealed in the leaves of B. x ornata and B. crassifolia (4.9 - 5.1 mg x g(-1)). Free radical scavenging power was determined by two methods--FRAP and NADH. The best free radical scavengers were B. crassifolia (FRAP: 6.7 - 15.9 mg GAE. 100g(-1); NADH: 20.3 - 50.9%) and B. ornata (FRAP: 13.7 - 15.2 mg GAE. 100g(-1); NADH: 29.3 - 31.1%). The lowest content of bergenin and the weakest radical scavenger was B. ciliata (bergenin: 3.1 mg x g(-1); FRAP: 5.5 - 11.0 mg GAE.100g(-1); NADH: 23.2 - 25.6%). The presence of a large percentage of bergenin is responsible for the radical scavenging activity, as shown by the results from the FRAP and NADH assays. Significant, positive correlation was found between bergenin content and radical scavenging activity in both methods.

    Sorting of waste takes place in two stages: First, the waste is dried to a moisture of 15 % by weight, making use of its microbial activities. After this, the stabilised residue is sorted according to grain size, density, magnetic susceiptibility, electric conductivity, and comminution characteristics. This way, recyclable materials are recovered almost completely (e.g. metals, stone, ceramics, glass). The refuse-derived fuel fraction has significantly lower heavy metal concentrations because the metals were sorted out, and its calorific value and homogemeity are optimised as well. The fuel fraction can be combusted at once or stored for further use. [German] Die stoffliche Trennung des Restabfalls kann in zwei aufeinander folgende Schritte unterteilt werden. Den ersten Schritt stellt eine Trocknung unter Ausnutzung der mikrobiellen Aktivitaeten des Materials dar. Durch diese Massnahme wird ein trockenes Material mit einer Restfeuchte von unter 15 Gew.-% erzeugt. Den zweiten Verfahrensschritt stellt die Sortierung des stabilisierten Restabfall dar. Als Sortierkriterium werden die Eigenschaften Korngroesse, Dichte, magnetische Suszeptibilitaet, elektrische Leitfaehigkeit und Zerkleinerungsverhalten angewandt. Hierdruch ist eine nahezu vollstaendige und sortenreine Rueckgewinnung der im Abfall enthaltenen Wertstoffe wie Eisen-/Nichteisenmetalle, Steine/Keramik und Glas sichergestellt. Weiterhin erhaelt man als Brennstofffraktion das Trockenstabilat {sup circledR}. Aufgrund der Abtrennung der hauptsaechlichen Schwermetalltraeger, Eisen- und Nichteisenmetalle, besitzt dieser Sekundaerbrennstoff gegenueber dem unbehandeltem Restabfall deutlich verminderte Schwermetallkonzentrationen. Zudem sind seine verbrennungstechnisch relevanten Eigenschaften Heizwert und Homogenitaet deutlich optimiert. Das Trockenstabilat {sup circledR} wird sofort oder zeitversetzt der energetischen Verwertung zugefuehrt. (orig.)

    Full Text Available ABSTRACT The objective of this study was to model the water sorption kinetics of damaged beans. Grains with initial moisture content of 53.85%, dry basis (d.b., were used. One portion of the grains was used to obtain desorption isotherms, while the other was subjected to drying until the moisture content of 5.26% (d.b., so that it was subjected to the adsorption. For the induction of damage, a Stein Breakage Tester was used. To obtain the equilibrium moisture content, grains were placed in a climatic chamber at 20, 30, 40 and 50 ± 1 °C combined with relative humidity of 30, 40, 50, 70 and 90 ± 3%. The GAB model fitted well to the equilibrium moisture experimental data of damaged grains and control. With increasing temperature, the monolayer moisture contents decreased in adsorption and desorption processes, ranging from 9.84 to 5.10% d.b. The lower moisture content in the monolayer in damaged grains indicates that lower moisture content is necessary to ensure their conservation.

    Harmful algal blooms (HABs) resulting from an explosive increase in algae population have become a global problem in coastal marine environment. During 3rd -8th, May of 2006, large-scale, mixed prorocentrum dentatum stein and skeletonema costatum bloom developed in those water off the coast of Zhejiang province (Zhoushan city and Liuheng Island) of China. Using Global Nested Air Quality Prediction Modeling System (GNAQPMS), we find an atmospheric transport of considerable nutrient matter (nitrate, ammonium, Fe (Ⅱ)) to East China Sea (ECS) before the red tide event. It be inferred that the atmospheric transport of nutrient matter is a significant source of nutrient matter in the water of East China Sea whose hydrological setting is dominated by oligotrophic Taiwan Warm Current in spring. Such atmospheric transport of nutrient matter is likely a cause factor of red tide in the coast of East China Sea, especially during dust event. The study provides new information for discovering the occurring mechanism of the red tides in ECS and the essential parameters for the red tide research.

    Full Text Available With the aim of investigating whether yessotoxin (YTX is responsible for diarrhetic shellfish poisoning (DSP events in Croatian waters, three different methods were combined: a modified mouse bioassay (MBA that discriminates YTX from other DSP toxins, the enzyme-linked immunosorbent assay method (ELISA and liquid chromatography-mass spectrometry (LC-MS/MS. Among 453 samples of mussels and seawater analyzed in 2007, 10 samples were DSP positive. Results obtained by the modified MBA method revealed that most of the samples were positive for YTX, with the exception of samples from Lim Bay (LB 1 The ELISA method also identified the presence of YTX in these samples. DSP toxin profiles showed the presence of okadaic acid (OA in three, and YTX in four out of nine samples that were analyzed by LC-MS/MS. The phytoplankton community structure pattern revealed Lingulodinium polyedrum (Stein Dodge, which was present in the water prior to and/or during toxicity events at low concentrations (80 to 1440 cells L-1, as a potential YTX producing species. It is proposed that L. polyedrum cells accumulated in mussels and the subsequently observed toxicity may be related to metabolism after ingestion, resulting in carboxy YTX as the major analog in the mussel.

  13. A Part-Time Solar Chromosphere?

    The dynamical model of the nonmagnetic chromosphere of Carlsson & Stein (1994) has a time-dependent temperature structure from shock dissipation of upward-propagating acoustic waves. For the high-temperature phase of waves due to an observed photospheric velocity spectrum, the model reproduces to great fidelity the intricate velocity and intensity variations of the corresponding H line from an hour-long observing run. But for the low-temperature phase, in which the temperature drops monotonically in the outward direction up to a height of at least 1.8 Mm above tau =1, the model predicts UV spectra for lines and continua that should be observable in absorption everywhere and almost all the time. However, observations with SUMER show only emission lines, everywhere and all the time. The dynamical model fails as a temperature model because it uses less than 5% of the wave energy entering the chromosphere. The extra energy is hidden in the observed power spectrum at acoustic frequencies above 10 mHz; it accounts for a permanent temperature inversion and thus a full-time chromosphere.

    The speckle noise is inherent to transthoracic echocardiographic images. A standard noise-free reference echocardiographic image does not exist. The evaluation of filters based on the traditional parameters such as peak signal-to-noise ratio, mean square error, and structural similarity index may not reflect the true filter performance on echocardiographic images. Therefore, the performance of despeckling can be evaluated using blind assessment metrics like the speckle suppression index, speckle suppression and mean preservation index (SMPI), and beta metric. The need for noise-free reference image is overcome using these three parameters. This paper presents a comprehensive analysis and evaluation of eleven types of despeckling filters for echocardiographic images in terms of blind and traditional performance parameters along with clinical validation. The noise is effectively suppressed using the logarithmic neighborhood shrinkage (NeighShrink) embedded with Stein's unbiased risk estimation (SURE). The SMPI is three times more effective compared to the wavelet based generalized likelihood estimation approach. The quantitative evaluation and clinical validation reveal that the filters such as the nonlocal mean, posterior sampling based Bayesian estimation, hybrid median, and probabilistic patch based filters are acceptable whereas median, anisotropic diffusion, fuzzy, and Ripplet nonlinear approximation filters have limited applications for echocardiographic images.

The Western dichotomy between children and adults characterize our opinion both on children and childhood. In this understanding framework the children are seen as something totally different from adults. Can artistic children's literature modify this habitual thinking about such hierarchical levels? The three books to examine closer have all won awards from Ministry of Culture as the best Norwegian picture book that year. Both Svein Nyhus: Pappa [Daddy] (1998, Hans Sande and Gry Moursund: Arkimedes og brødskiva [Archimedes and the Sandwich] (2000 and Stein Erik Lunde and Øyvind Torseter: Eg kan ikkje sove no [I Can't Sleep Now] (2008 are first-person narratives where the main character is a child. In such picture books visual and verbal point of view rarely are the same. The illustrations usually observe the central character from a distance and then allow the reader not only to adopt the narrator's point of view. What kind of ambiguities in the complex relationship between text and images give signals to the readers–and to the understanding of the narrator's position and perspective? What can this perspective and the iconotext in the three books tell us about today's children's role?

    In this paper we investigate Riesz transforms R μ ( k) of order k≥1 related to the Bessel operator Δμ f( x)=- f”( x)-((2μ+1)/ x) f’( x) and extend the results of Muckenhoupt and Stein for the conjugate Hankel transform (a Riesz transform of order one). We obtain that for every k≥1, R μ ( k) is a principal value operator of strong type ( p, p), p∈(1,∞), and weak type (1,1) with respect to the measure dλ( x)= x 2μ+1 dx in (0,∞). We also characterize the class of weights ω on (0,∞) for which R μ ( k) maps L p (ω) into itself and L 1(ω) into L 1,∞(ω) boundedly. This class of weights is wider than the Muckenhoupt class mathcal{A}p^μ of weights for the doubling measure dλ. These weighted results extend the ones obtained by Andersen and Kerman.

    Full Text Available On December 24, 1935, James Weldon Johnson read thirteen of his poems at Columbia University, in a recording session engineered by Columbia Professor of Speech George W. Hibbitt and Barnard colleague Professor W. Cabell Greet, pioneers in the field that became sociolinguistics. Interested in American dialects, Greet and Hibbitt used early sound recording technologies to preserve dialect samples. In the same lab where they recorded T.S. Eliot, Gertrude Stein, and others, James Weldon Johnson read a selection of poems that included several from his seminal collection God’s Trombones and some dialect poems. Mustazza has digitized these and made them publicly available in the PennSound archive. In this essay, Mustazza contextualizes the collection, considering the recordings as sonic inscriptions alongside their textual manifestations. He argues that the collection must be heard within the frames of its production conditions—especially its recording in a speech lab—and that the sound recordings are essential elements in an hermeneutic analysis of the poems. He reasons that the poems’ original topics are reframed and refocused when historicized and contextualized within the frame of The Speech Lab Recordings.

    To compare the heat production of longitudinal versus torsional phacoemulsification under strict laboratory test conditions. Department of Ophthalmology, David Geffen School of Medicine at UCLA, and Jules Stein Eye Institute, Los Angeles, California, USA. Two Infiniti phacoemulsification handpieces were inserted into silicone test chambers filled with a balanced salt solution and imaged serially using a thermal camera. Incision compression was simulated by suspending 25.3 g weights from the silicone chambers. To simulate occlusion of the phacoemulsification tip, the aspiration line was clamped. Peak temperatures were measured 0, 10, 30, 60, and 120 seconds after the commencement of continuous ultrasound power. The 2 handpieces, operating exclusively in longitudinal or torsional modes, were compared 3 ways: (1) using the same power displayed on the instrument console, (2) using identical stroke lengths, and (3) using the same applied energy, a product of stroke length and frequency. For all 3 comparisons, torsional phacoemulsification resulted in lower temperatures at each time point. At the same displayed power setting, the scenario most familiar to cataract surgeons, longitudinal phacoemulsification elevated temperatures up to 41.5 degrees C more than torsional phacoemulsification. Torsional phacoemulsification generated less heat than longitudinal phacoemulsification in all 3 comparison tests. Lower operating temperatures indicate lower heat generation within the same volume of fluid, and this may provide additional thermal protection during cataract surgery.

Jules Stein Eye Institute and Department of Ophthalmology, David Geffen School of Medicine at UCLA, Los Angeles, California, USA. The vacuum rise time under normal and enhanced aspiration modes, vacuum limit accuracy, and occlusion break surge of the Infiniti Vision System, Stellaris Vision Enhancement System, and WhiteStar Signature Phacoemulsification System were tested. Vacuum rise time and limit accuracy were measured at limit settings of 400 mm Hg and 600 mm Hg. Surge area was recorded at vacuum limit settings of 200 mm Hg, 300 mm Hg, 400 mm Hg, and 500 mm Hg. The Infiniti had the fastest vacuum rise times under normal and enhanced aspiration modes. At 4 seconds, the vacuum limit accuracy was greatest with the Infiniti at the 400 mm Hg limit and the Signature at the 600 mm Hg limit. The Stellaris did not reach either vacuum target. The Infiniti performed better than the other 2 machines during testing of occlusion break surge at all vacuum limit settings above 200 mm Hg. Under controlled laboratory test conditions, the Infiniti had the fastest vacuum rise time, greatest vacuum limit accuracy at 400 mm Hg, and least occlusion break surge. These results can be explained by the lower compliance of the Infiniti system.

    Paulo C. Corrêa

    Full Text Available ABSTRACT This study aims to determine the thermodynamic properties of damaged beans. Grains with initial moisture content of 53.85% (d.b. were used. A part of the grains was used to obtain the desorption isotherms, while another part was subjected to drying until a moisture content of 5.26% (d.b. was achieved; therefore, it was subjected to the adsorption process. To induce damage, a Stein breakage tester was used. To obtain the equilibrium moisture content, grains were placed in a climatic chamber whose temperatures were 20, 30, 40, and 50 ± 1 °C combined with a relative humidity of 30, 40, 50, 70, and 90 ± 3%. Although in the desorption process, damaged grains had a lower differential enthalpy compared with the control, the reverse behavior was observed in the adsorption process. Mechanical damage caused the formation of a greater number of available adsorption sites, resulting in higher differential entropy values in adsorption and lower values in desorption compared with the control. The mechanical damage had no effect on the Gibbs free energy.

    Full Text Available Through the analysis of Monoceros (2011, a novel by Canadian contemporary writer Suzette Mayr, we examine the entanglement between concepts of violence and abjection in literature. Mayr presents several characters that come into contact as a result of a suicide committed by a previously bullied student of a Catholic school. With the narrative as a reference, we propose to discuss the growing violence inside the school system in contemporary times, in this case as a result of sexual intolerance. Works by Nan Stein and Melinda York, who address the imposition of too strict gender roles on female and male students as one of the causes for violent outcomes among youngsters, will be our main theoretical references. We also discuss the topic of desire and abjection, mainly developed by Kristeva and Kulzbach, as illuminating perspectives for the analysis of the selected novel. We suggest that in Monoceros bullying is performed to guarantee fixed and binary models of gender identity, which ends up by promoting low self-esteem and feelings of awkwardness on individuals defined as different from the norm.

Regarding the surface reflectance, we found that Lutetia has a distinctly different albedo and slope than both the asteroid (2867) Steins and Earth's moon, the two most analogous objects studied in the far ultraviolet (FUV). Further, Lutetia's ∼10% geometric albedo near 1800 A is significantly lower than its 16%-19% albedo near 5500 A. Moreover, the FUV albedo shows a precipitous drop (to ∼4%) between 1800 A and 1600 A, representing the strongest spectral absorption feature observed in Lutetia's spectrum at any observed wavelength. Our surface reflectance fits are not unique but are consistent with a surface dominated by an EH5 chondrite, combined with multiple other possible surface constituents, including anorthite, water frost, and SO 2 frost or a similar mid-UV absorber. The water frost identification is consistent with some data sets but inconsistent with others. The anorthite (feldspar) identification suggests that Lutetia is a differentiated body.

  6. Quantum field theory in curved space-times: with an application to the reduced model of deSitter universe

    Peter, I. J.

    1995-06-01

    The work deals with space-times with fixed background metric. The topics were arranged in a straight course, the first chapter collects basic facts on Lorentzian manifolds as time-orientability, causal structure, ... Further free neutral scalar fields and spinor fields described by the Klein-Gordon equation resp. the Dirac equation are dealt with. Having in mind the construction of the Weyl algebra and the Fermi algebra in the second chapter, it was put emphasis on the structure of the spaces of solutions of these equations: In the first case the space of solutions is a symplectic vector space in a canonical manner, in the second case a Hilbert space. It was made some effort to stay as general as possible. Most of the material in the second chapter already exists for several years, but it is largely scattered over various journal articles. In the third chapter the construction of a vacuum on the special example of deSitter universe is described. A close investigation of a recent work by J. Bros and U. Moschella made it possible to refine a result concerning temperature felt by an accelerated observer in deSitter space. The last part of this thesis is concerned with vacua for spinor fields on the two-dimensional deSitter universe. A procedure introduced by R. Haag, H. Narnhofer and U. Stein for four dimensional space-times does not seem to work in two dimensions. (author)

    Full Text Available This paper presents an empirical investigation to study the effects of institutional ownership, internal audit system, the number of non-executive board members and having differentiation between chair and general managers’ responsibilities on the likelihood of stock price crash on 110 listed firms on Tehran Stock Exchange over the period 2004-2011. The study uses Chen’ model (2001 [Chen, J., Hong, H., & Stein, J. C. (2001. Forecasting crashes: Trading volume, past returns, and conditional skewness in stock prices. Journal of Financial Economics, 61(3, 345-381.] to perform the investigation. Based on the results of the survey, there is a negative and meaningful relationship between stock price crash and institutional ownership when the level of significance is ten percent. In addition, as the number of non-executive board members increases, the chance of stock price crash decreases when the level of significance is five percent. However, separation between the responsibility of chair and general managers did not seem to influence on stock price and also having internal audit system had no impact on the likelihood of stock price change.

  8. Welfare state: Milestones of development and the current status

    Full Text Available The article describes the evolution of ideas about the social state as a fair state based on the concept of the social contract. L. von Stein argues that the purpose of the welfare state was not changing the class structure of society and the elimination of the contradictions between the classes, but rather balancing and minimizing conflicts with the help of property transformations allowing a person to change one’s class affiliation. The main condition for the existence of the welfare state is its policies compliance with the interests of citizens, which provides political stability and social security. The central idea of the welfare constitutional state is that the rights of citizens are guaranteed by the state. The functions of the state and its social responsibilities were transforming over time mainly due to the erosion of state, private and corporate responsibility for providing social services. In most cases, the social programs are developed by the state, but they can also be provided by commercial organizations in the “consumer society”, in which all things and services have a material value and benefit. The welfare state is based on the principle of social justice in the distribution of wealth among the population, thus, every democratic state seeks to become a welfare state, which implies a high level of confidence in the government.

    Andréa Franco Milagres

    Full Text Available O artigo discute o estatuto do corpo na esquizofrenia a partir de reiterados episódios de automutilação. O corpo é abordado a partir das referências freudianas sobre o narcisismo, e de J. Lacan sobre o Estádio do Espelho, propondo tomar o narcisismo como um nó fundamental e discutindo as possíveis conseqüências de uma falha nesta função psíquica. Utilizamos como procedimento o estabelecimento de um paralelo entre um caso clínico e as discussões trazidas por Lacan em dois diferentes momentos a respeito da noção de corpo. Primeiramente a partir do caso de Lol V. Stein, no romance O deslumbramento, de Marguerite Duras, e, posteriormente, a partir do caso de James Joyce, especificamente no episódio da surra, relatado por ele em Um retrato do artista quando jovem. À guisa de conclusão, apontamos que a solução encontrada por nosso sujeito difere dos dois casos comentados por Lacan, mas visariam a uma operação semelhante: constituir um corpo definido enquanto superfície onde algo se inscreve introduzindo um sinal negativo.

    All the necessary ingredients were there - laughs, scientific debate and a pinch of emotion - to make the «Festkolloquium», held in honour of Heinrich Wahl, an unqualified success. One by one, his colleagues, friends and former students took their turn on the rostrum in CERN's main auditorium to reminisce over the career, scientific contributions and leadership of this highly-respected physicist. For, believe it or not, after 34 years at the forefront of the Laboratory's charge-parity violation experiments, Heinrich Wahl, is finally retiring from CERN. Heinrich Wahl during the Colloquium for his retirement.Heinrich Wahl came to CERN from his native Germany as a Fellow in 1969 and rapidly made a name for himself in the first CP violation experiments on neutral kaons, a field that would subsequently become his main area of interest. He then became involved in the CDHS (CERN Dortmund Heidelberg Saclay) experiment to study high-energy neutrino interactions, which began in 1976 under the leadership of Jack Stein...

    TRIO (Triplet Ionospheric Observatory) CINEMA ( Cubesat for Ion, Neutral, Electron, MAg-netic fields) is a space science mission with three identical cubesats. The main scientific objec-tives are a multi-observation of ionospheric ENA (Energetic Neutral Atom) imaging, ionospheric signature of suprathermal electrons and ions and complementary measurements of magnetic fields for particle data. For this, Main payloads consist of a suprathermal electron, ion, neutral (STEIN) instrument and a 3-axis magnetometer of magnetoresistive sensors. The CINEMA is a 3-unit CubeSat, which translates to a 10 cm x 10 cm x 30 cm in volume and no more than four kilograms in mass. An attitude control system (ACS) uses torque coils, a sun sensor and the magnetometers and spin CINEMA spcaecraft 4 rpm with the spin axis perpendicular to the ecliptic plane. CINEMA will be placed into a high inclination low earth orbit that crosses the auroral zone and cusp. Three institutes are collaborating to develop CINEMA cubesats: i) two cubesats by Kyung Hee University (KHU) under their World Class University (WCU) program, ii) one cubesat by UC Berkeley under the NSF support, and iii) three magnetometers are provide by Imperial College, respectively. In this paper, we describe the system design and their performance of TR IO cinema mission. TRIO cinema's development of miniature in-strument and spacecraft spinning operation will play an important role for future nanosatellite space missions

  12. An examination of the association between interviewer question type and story-grammar detail in child witness interviews about abuse.

    2010-06-01

    This study compared the effects of open-ended versus specific questions, and various types of open-ended questions, in eliciting story-grammar detail in child abuse interviews. The sample included 34 police interviews with child witnesses aged 5-15 years (M age=9 years, 9 months). The interviewers' questions and their relative sub-types were classified according to definitions reported in the child interview training literature. The children's responses were classified according to the proportion of story grammar and the prevalence of individual story grammar elements as defined by Stein and Glenn (1979). Open-ended questions were more effective at eliciting story grammar than specific questions. This finding was revealed across three age groups, two interview phases and irrespective of how question effectiveness was measured. However, not all types of open-ended questions were equally effective. Open-ended questions that encouraged a broad response, or asked the child to elaborate on a part of their account, elicited more story-grammar detail compared to open-ended questions that requested clarification of concepts or descriptions of the next (or another) activity or detail within a sequence. This study demonstrates that children's ability to provide story-grammar detail is maximised when there is minimal prompting from the interviewer. Given the association between story grammar production and victim credibility, greater guidance is warranted in interviewer training programs in relation to the effects and administration of different types of open-ended questions.

The congress was organised by the principle of the health resort at the time Professor Dr Julius Glax, and consisted of two separate parts. The first part was held in Opatija from October 13 until 15, 1904. There were lectures, auto-papers, summaries, reports, discussions, and the afternoon expert trip to Crikvenica by boat. In Opatija the participants were shown the spa park, the rehabilitation paths for patients with heart difficulties, marine baths Angiolona and Slatina, the covered spa Erzherzog Ludwig Viktor Bad, and of the health institution Zander Institute. At the accompanying exhibition the Austrian and German companies represented their products, among them still recognised Bayer, C. Reichert in Karl Zeiß. Additionally, the owner of the Zanderinstitut in Opatija Dr Isor Stein presented his own therapeutic aid exerciteur there. The first part of the congress concluded on October 15, 1904 with the great banquet in the hotel Stephanie.The second part of the congress was held from October 16 until 20, 1904. The expert trip was organised to the Austrian Riviera on the Pannonia ship. The participants visited attractions and health institutions in Mali Lošinj, Pula, Brijuni, Rovinj, Grado, Aquileia and Trieste, where they also had expert lectures. The closing ceremony of the second part of the congress was in Trieste, from where the participants returned to Vienna by the special train.

  14. Separators/reheaters for nuclear turbines

    International Nuclear Information System (INIS)

    Guignard, S.

    1986-01-01

    During the past few years, the Nuclear Department of Stein Industrie has implemented a broad development programme for the design of superheating separators for nuclear power plant turbines. These units separate the water in the steam leaving the high-pressure section, and superheat the dry steam before expansion in the medium - and low - pressure sections. Thorough research, confirmed by tests, was conducted in different areas, and especially on problems of water and steam separation, and heat transfers in the tube bundle(s) required to superheat the steam. Special systems were designed to avoid processes detrimental to the operation of the units, such as vibrations, erosion/corrosion etc. Experimental feedback on the superheating separators of 900 MW nuclear power plants helped to substantiate the assumptions made for the thermal and hydraulic calculations, as well as the optimizations carried out on the different functions. These results confirmed the industrial application of the design methods to other superheating separators intended for 1300 MW nuclear power plants and for export [fr

  15. How to (properly) strengthen Bell's theorem using counterfactuals

    Science.gov (United States)

    Bigaj, Tomasz

    Bell's theorem in its standard version demonstrates that the joint assumptions of the hidden-variable hypothesis and the principle of local causation lead to a conflict with quantum-mechanical predictions. In his latest counterfactual strengthening of Bell's theorem, Stapp attempts to prove that the locality assumption itself contradicts the quantum-mechanical predictions in the Hardy case. His method relies on constructing a complex, non-truth functional formula which consists of statements about measurements and outcomes in some region R, and whose truth value depends on the selection of a measurement setting in a space-like separated location L. Stapp argues that this fact shows that the information about the measurement selection made in L has to be present in R. I give detailed reasons why this conclusion can and should be resisted. Next I correct and formalize an informal argument by Shimony and Stein showing that the locality condition coupled with Einstein's criterion of reality is inconsistent with quantum-mechanical predictions. I discuss the possibility of avoiding the inconsistency by rejecting Einstein's criterion rather than the locality assumption.

    A naked dinoflagellate with a unique arrangement of chloroplasts in the center of the cell was isolated from the northern Baltic proper during a spring dinoflagellate bloom (March 2005). Morphological, ultrastructural, and molecular analyses revealed this dinoflagellate to be undescribed and belonging to the genus Gymnodinium F. Stein. Gymnodinium corollarium A. M. Sundström, Kremp et Daugbjerg sp. nov. possesses features typical of Gymnodinium sensu stricto, such as nuclear chambers and an apical groove running in a counterclockwise direction around the apex. Phylogenetic analyses based on partial nuclear-encoded LSU rDNA sequences place the species in close proximity to G. aureolum, but significant genetic distance, together with distinct morphological features, such as the position of chloroplasts, clearly justifies separation from this species. Temperature and salinity experiments revealed a preference of G. corollarium for low salinities and temperatures, confirming it to be a cold-water species well adapted to the brackish water conditions in the Baltic Sea. At nitrogen-deplete conditions, G. corollarium cultures produced small, slightly oval cysts resembling a previously unidentified cyst type commonly found in sediment trap samples collected from the northern and central open Baltic Sea. Based on LSU rDNA comparison, these cysts were assigned to G. corollarium. The cysts have been observed in many parts of the Baltic Sea, indicating the ecologic versatility of the species and its importance for the Baltic ecosystem. © 2009 Phycological Society of America.

    In signal processing, the region of abrupt changes contains the most of the useful information about the nature of the signal. The region or the points where these changes occurred are often termed as singular point or singular region. The singularity is considered to be an important character of the signal, as it refers to the discontinuity and interruption present in the signal and the main purpose of the detection of such singular point is to identify the existence, location and size of those singularities. Electrocardiogram (ECG) signal is used to analyze the cardiovascular activity in the human body. However the presence of noise due to several reasons limits the doctor's decision and prevents accurate identification of different pathologies. In this work we attempt to analyze the ECG signal with energy based approach and some heuristic methods to segment and identify different signatures inside the signal. ECG signal has been initially denoised by empirical wavelet shrinkage approach based on Steins Unbiased Risk Estimate (SURE). At the second stage, the ECG signal has been analyzed by Mallat approach based on modulus maximas and Lipschitz exponent computation. The results from both approaches has been discussed and important aspects has been highlighted. In order to evaluate the algorithm, the analysis has been done on MIT-BIH Arrhythmia database; a set of ECG data records sampled at a rate of 360 Hz with 11 bit resolution over a 10mv range. The results have been examined and approved by medical doctors.

  18. Skepticism, empathy, and animal suffering.

    Aaltola, Elisa

    2013-12-01

    The suffering of nonhuman animals has become a noted factor in deciding public policy and legislative change. Yet, despite this growing concern, skepticism toward such suffering is still surprisingly common. This paper analyzes the merits of the skeptical approach, both in its moderate and extreme forms. In the first part it is claimed that the type of criterion for verification concerning the mental states of other animals posed by skepticism is overly (and, in the case of extreme skepticism, illogically) demanding. Resting on Wittgenstein and Husserl, it is argued that skepticism relies on a misguided epistemology and, thus, that key questions posed by it face the risk of absurdity. In the second part of the paper it is suggested that, instead of skepticism, empathy together with intersubjectivity be adopted. Edith Stein's take on empathy, along with contemporary findings, are explored, and the claim is made that it is only via these two methods of understanding that the suffering of nonhuman animals can be perceived.

    2016-01-01

    The purpose of this book is to present the classical analytic function theory of several variables as a standard subject in a course of mathematics after learning the elementary materials (sets, general topology, algebra, one complex variable). This includes the essential parts of Grauert–Remmert's two volumes, GL227(236) (Theory of Stein spaces) and GL265 (Coherent analytic sheaves) with a lowering of the level for novice graduate students (here, Grauert's direct image theorem is limited to the case of finite maps). The core of the theory is "Oka's Coherence", found and proved by Kiyoshi Oka. It is indispensable, not only in the study of complex analysis and complex geometry, but also in a large area of modern mathematics. In this book, just after an introductory chapter on holomorphic functions (Chap. 1), we prove Oka's First Coherence Theorem for holomorphic functions in Chap. 2. This defines a unique character of the book compared with other books on this subject, in which the notion of coherence appear...

    Three new species of shoot fly, Atherigona Rondani (subgenus Acritochaeta Grimshaw) (Diptera: Muscidae), are described from northern Thailand, based on morphological characteristics of males. Unique features of A. komi sp. n. include a distinct spiral groove on the dorsal aspect of the fore femur and two dark apical wing spots, whereas A. chiangmaiensis sp. n. is recognized by the presence of one large patch on the apical wing spot, appearing as a large and smaller wave-shaped patch, and no distinct pattern on tergites. A. thailandica sp. n. displays a remarkable dark boomerang-shaped patch along the wing margin and fore femur, with two rows of long hairs on the dorsal surface. Male terminalia are also different in the new species, showing distinctive characteristics. This paper also presents five newly recorded species in Thailand; Atherigona maculigera Stein, Atherigona ovatipennis vietnamensis Shinonaga et Thinh, Atherigona pallidipalpis Malloch, Atherigona seticauda Malloch, and Atherigona setitarsus Shinonaga et Thinh. A key is provided for the adult males of Atherigona recorded in Thailand, all belonging to the subgenus Acritochaeta, except for A. soccata Rondani. PMID:22233520

    Full Text Available Capital structure selection is fundamentally important in corporate financial management as it influence on mutually return and risk to stakeholders. Despite of Malaysia’s position as one of the major players of Islamic Financial Market, there are still lack of studies has been conducted on the capital structure of shariah compliant firms especially related to hybrid securities. The objective of this study is to determine the hybrid securities issuance model among the shariah compliant firms in Malaysia. As such, this study is to expand the literature review by providing comprehensive analysis on the hybrid capital structure and to develop dynamic Islamic hybrid securities model for shariah compliant firms. We use panel data of 50 companies that have been issuing the hybrid securities from the year of 2004- 2012. The outcomes of the studies are based on the dynamic model GMM estimation for the determinants of hybrid securities. Based on our model, risk and growth are considered as the most determinant factors for issuing convertible bond and loan stock. These results suggest that, the firms that have high risk but having good growth prospect will choose hybrid securities of convertible bond. The model also support the backdoor equity listing hypothesis by Stein (1992 where the hybrid securities enable the profitable firms to venture into positive NPV project by issuing convertible bond as it offer lower coupon rate as compare to the normal debt rate

    Full Text Available ABSTRACT Fanniidae (Insecta: Diptera is a relatively small family (ca. 350 spp. with five genera, of which Fannia Robineau-Desvoidy, 1830 and Euryomma Stein, 1899 have Neotropical distributions. Some of these species are almost always found in forensic studies. Forensically relevant species have been neglected, despite recent forensic studies that suggest their importance for estimating post-mortem interval (PMI. Thus, current and updated keys to identify adults or larvae on carcasses are unavailable for the most important species. While immature stages are important in estimating PMI, evidence suggests that adults (Fanniidae as well as other families may also be useful for this purpose. Here we provide a key to males of the species of Fanniidae (found on corpses and other decomposing organic matter with a checklist of species that have been used in forensics in the Neotropical region. The key comprises all 38 species of Fannia and Euryomma that have already been successfully used in forensics, and species that are potentially useful for estimating PMI. These records were found after reviews of the literature and data from entomological collections. Photographs and illustrations of the main characters in the key are provided.

    This paper presents and discusses 30 cases of cadavers that had been transferred for forensic entomology investigations to the Department of Forensic Medicine, Faculty of Medicine, Chiang Mai University, northern Thailand, from 2000 to 2006. Variable death scenes were determined, including forested area and suburban and urban outdoor and indoor environments. The fly specimens found in the corpses obtained were the most commonly of the blow fly of family Calliphoridae, and consisted of Chrysomya megacephala (F.), Chrysomya rufifacies (Macquart) Chrysomya villeneuvi Patton, Chrysomya nigripes Aubertin, Chrysomya bezziana Villeneuve, Chrysomya chani Kurahashi, Lucilia cuprina (Wiedemann), Hemipyrellia ligurriens (Wiedemann), and two unknown species. Flies of the family Muscidae [Hydrotaea spinigera Stein, Synthesiomyia nudiseta (Wulp)], Piophilidae [Piophila casei (L.)], Phoridae [Megaselia scalaris (Loew)], Sarcophagidae [Parasarcophaga ruficornis (F.) and three unknown species], and Stratiomyiidae (Sargus sp.) were also collected from these human remains. Larvae and adults of the beetle, Dermestes maculatus DeGeer (Coleoptera: Dermestidae), were also found in some cases. Chrysomya megacephala and C. rufifacies were the most common species found in the ecologically varied death scene habitats associated with both urban and forested areas, while C. nigripes was commonly discovered in forested places. S. nudiseta was collected only from corpses found in an indoor death scene.

    Full Text Available Our own body, both as a physical object (Körper and as a focus experiencing sensations (Leib is usually the axis of our self-identification. In this the mode of presentation of one's own body, in correlation of its accessibility "from the outside" and "from the inside", in which I receive my own body as one and the same, however, one cannot find an answer to the question about how can the bodily (corporal identification be constituted, which does not have a uniaxial character as it is, e.g. in case of the painterly perception of trompe-l'oeil or during the film showing. Projection of one's own body, as is suggested by phenomenological studies of Edith Stein and Leopold Blaustein, may consist in suspending the direct relation to Körper when the basis of identification is merely Leib, which we experience in dislocation, in an unclear connection with the border of the field of imagined space. An important feature of this situation is that during projection of the spectator's body into the field of an image to suspension is submitted not only the feeling of the body as a physical datum, but also space which remains as its real surrounding. The problems touched upon here can be considered as prolegomena to the phenomenology of a spectator-in-aspectacle.

    We discuss Replica Symmetry Breaking (RSB) in Spin Glasses. We present an update about the state of the matter, both from the analytical and from the numerical point of view. We put a particular attention in discussing the difficulties stressed by Newman and Stein concerning the problem of constructing pure states in spin glass systems. We mainly discuss about what happens in finite dimensional, realistic spin glasses. Together with a detailed review of some of most important features, facts, data, phenomena, we present some new theoretical ideas and numerical results. We discuss among others the basic idea of the RSB theory, correlation functions, interfaces, overlaps, pure states, random field and the dynamical approach. We present new numerical results for the behavior of coupled replicas and about the numerical verification of sum rules, and we review some of the available numerical results that we consider of larger importance (for example the determination of the phase transition point, the correlation functions, the window overlaps, the dynamical behavior of the system).

    Full Text Available Researches of the correlates of the national identity are plentiful both in Serbian and foreign literature. However, in the past decade or so, a new social identity starts to make its way into the researches of the social psychologists-European identity or the sense of belonging to the Europe and the Europeans. This paper deals with the relation between national and European identity, as well as with the correlates of both of these, or one of them. The sample consisted of 451 subjects, all residents of major cities in the Vojvodina region (northern Serbia, divided into several categories-ethnicity (Serbs and Hungarians, educational level (primary and secondary school or University degree, gender and age. Several scales have been used: Cinnirela's national and European identity scale, Collective self-esteem scale, scale measuring attitudes towards the European integration-STEIN and Social dominance orientation scale-SDO. The questionnaire with the demographic characteristics has also been the part of the instrument. The research has been conducted in 2005 and 2006 in the all of the major Vojvodinian cities. Results show the relation between national and European identity is foggy, but general conclusion is that we can observe them as independent identities. The correlates of the national identity were ethnicity, high social dominance orientation, high collective self-esteem and negative attitude towards the European integrations. Correlates of the European identity were fewer: ethnicity, positive attitude towards the European integration and low social dominance orientation.

    Many important fields of research had a humble origin. In the distant past, A J P Martin's discovery that amino acids could be separated by paper chromatography and Moore and Stein's use of columns for quantitative amino acid analysis provided the first steps towards the determination of structure in complex biologically active molecules. They opened the door to reveal the essential relationship that exists between structure and function. In molecular endocrinology, for example, striking advances have been made by chemists with their expertise in the identification of structure working with biologists who contributed valuable knowledge and experience. Advantage was gained from the convergence of different background, and it is notable that the whole is greater than the sum. In the determination of structure, it may be recalled that four of the world's great pioneers (Archibald Martin, Rodney Porter, Fred Sanger and Vincent du Vigneaud) were acknowledged for their fundamental contributions when individually they were awarded the Nobel Prize. They foresaw that the identification of structure would prove of outstanding importance in the future. Indeed, study of the structures of β-endorphin and enkephalin and the different forms of opiate activity they engender has led to a transformation in our understanding of chemical transmission in the brain. © 2016 Society for Endocrinology.

  11. [Comment on “Should Memphis build for California's earthquakes?”] from S.E. Hough

    Hough, Susan E.

    The recent article by Seth Stein, Joseph Tomasello, and Andrew Newman raised thought-provoking questions about one of the most vexing open issues in hazard assessment in the United States: the hazard posed by ostensibly infrequent, large, mid-continental earthquakes. Many of the technical issues raised by this article are addressed by A. D. Frankel in the accompanying comment. I concur with this, and will only address and/or elaborate on a few additional issues here: (1) Detailed paleoseismic investigations have shown that the New Madrid region experienced sequences of large earthquakes around 900 and 1450 A.D.in addition to the historic events in 1811-1812. With a repeat time on the order of 400-500 years, these cannot be considered infrequent events. Paleoseismic investigations also reveal evidence that the prehistoric “events” were also sequences of two to three large earthquakes with a similar overall distribution of liquefaction in the greater New Madrid region as produced by the 1811-1812 sequence [Tuttle et al., 2002]. And if, as evidence suggests, the zone produces characteristic earthquakes, one will not see a commensurate rate of moderate events, as would be the case if seismicity followed the Gutenburg-Richter distribution.

    Full Text Available Is it possible a comparison between phenomenology and neurosciences, empathical Erlebnis and embodied cognition or simulation? The phenomenological living body is really the same of the neurophisiological one? What is the philosophical difference between culture and nature? The thesis asserted here is that intersubjectivity constitutes the originary root of personal subjectivity. It is proved through the empathical Erlebnis analysis elaborated by Edmund Husserl and Edith Stein, which allows for the phenomenologico-anthropological foundation of personal otherness and for the deep sense of the world as common space of action, connected to the identification of the essential structure of human being: living body (Leib as psycho-physical dimension, soul (Seele as nucleus or centre of personal identity, via individuationis and spirit (Geist as intentional life and activity of consciousness. To answer these questions, I follow two phenomenological paths: the first one is the Logos and Leib philosophical nexus, meaning the subject-body; the second is the link between empathy and otherness, meaning the roots intersubjectivity. That is why from my point of view phenomenology means a first person philosophy.

  13. A novel SURE-based criterion for parametric PSF estimation.

    We propose an unbiased estimate of a filtered version of the mean squared error--the blur-SURE (Stein's unbiased risk estimate)--as a novel criterion for estimating an unknown point spread function (PSF) from the degraded image only. The PSF is obtained by minimizing this new objective functional over a family of Wiener processings. Based on this estimated blur kernel, we then perform nonblind deconvolution using our recently developed algorithm. The SURE-based framework is exemplified with a number of parametric PSF, involving a scaling factor that controls the blur size. A typical example of such parametrization is the Gaussian kernel. The experimental results demonstrate that minimizing the blur-SURE yields highly accurate estimates of the PSF parameters, which also result in a restoration quality that is very similar to the one obtained with the exact PSF, when plugged into our recent multi-Wiener SURE-LET deconvolution algorithm. The highly competitive results obtained outline the great potential of developing more powerful blind deconvolution algorithms based on SURE-like estimates.

    Full Text Available O crédito direto ao consumidor é concedido de forma massificada por meio de modelos informatizados de credit scoring que visam eliminar os maus pagadores, assim evitando prejuízos financeiros decorrentes da inadimplência. No entanto, ao recusarem os maus pagadores, esses modelos, balanceados por critérios meramente financeiros, também recusam um grande número de bons pagadores, o que pode reduzir o potencial de ganhos da empresa varejista. Esta pesquisa teve por objetivo mostrar que, incluindo a margem operacional para definir o ponto de corte para concessão de crédito, a rentabilidade da empresa pode melhorar. Foram utilizadas a medida estatística Receiver Operating Characteristic (ROC e a abordagem de Stein (2005 para construir simulações em torno de valores reais praticados no mercado, as quais permitiram confirmar que, ao flexibilizar o ponto de corte levando em consideração a margem operacional, o resultado geral da empresa pode ser maximizado.

    This systematic review examined 140 outcome evaluations of primary prevention strategies for sexual violence perpetration. The review had two goals: 1) to describe and assess the breadth, quality, and evolution of evaluation research in this area; and 2) to summarize the best available research evidence for sexual violence prevention practitioners by categorizing programs with regard to their evidence of effectiveness on sexual violence behavioral outcomes in a rigorous evaluation. The majority of sexual violence prevention strategies in the evaluation literature are brief, psycho-educational programs focused on increasing knowledge or changing attitudes, none of which have shown evidence of effectiveness on sexually violent behavior using a rigorous evaluation design. Based on evaluation studies included in the current review, only three primary prevention strategies have demonstrated significant effects on sexually violent behavior in a rigorous outcome evaluation: Safe Dates (Foshee et al., 2004); Shifting Boundaries (building-level intervention only, Taylor, Stein, Woods, Mumford, & Forum, 2011); and funding associated with the 1994 U.S. Violence Against Women Act (VAWA; Boba & Lilley, 2009). The dearth of effective prevention strategies available to date may reflect a lack of fit between the design of many of the existing programs and the principles of effective prevention identified by Nation et al. (2003).

    This special issue of The Clinical Neuropsychologist focuses on advances in the emerging subspecialty of pediatric neuropsychology. The national and international contributions in this issue cover a range of key clinical, research, training, and professional issues specific to pediatric neuropsychology. The genesis for this project developed out of a series of talks at the Philadelphia Pediatric Neuropsychology Symposium in 2010, hosted by the Stein Family Fellow, the Department of Psychology of the College of Arts and Sciences at Drexel University, and the Philadelphia Neuropsychology Society. Articles that explore clinical practice issue focus on the assessment of special medical populations with congenital and/or acquired central nervous system insults. Research articles investigate the core features of developmental conditions, the use of technology in neuropsychological research studies, and large sample size genomic, neuropsychological, and imaging studies of under-represented populations. The final series of articles examine new considerations in training, advocacy, and subspecialty board certification that have emerged in pediatric neuropsychology. This introductory article provides an overview of the articles in this special issue and concluding thoughts about the future of pediatric neuropsychology.

  17. Use of a valve operation test and evaluation system to enhance valve reliability

    Power plant owners have emphasized the need for assuring safe, reliable operation of valves. While most valves must simply open or close, the mechanisms involved can be quite complex. Motor operated valves (MOVs) must be properly adjusted to assure operability. Individual operator components determine the performance of the entire MOV. Failure in MOVs could cripple or shut down a unit. Thus, a complete valve program consisting of design reviews, operational testing, and preventive and predictive maintenance activities will enhance an owner's confidence level that his valves win operate as expected. Liberty's Valve Operation Test and Evaluation System (VOTES) accurately measures stein thrust without intruding on valve operation. Since mounting a strain gage to a valve stem is a desirable but impractical way of obtaining precise stem thrust, Liberty developed a method to obtain identical data by placing a strain gage sensor on the valve yoke. VOTES provides information which effectively eliminates costly, unscheduled downtime. This paper presents the results of infield VOTES testing. The system's proven ability to identify and characterize actuator and valve performance is demonstrated. Specific topics of discussion include the ability of VOTES to ease a utility's IE Bulletin 8543 concerns and conclusively diagnose MOV components. Data from static and differential pressure testing are presented. Technical, operational, and financial advantages resulting from VOTES technology are explored in detail

    Full Text Available A common way to measure and stimulate narrative child development is through the retelling of a story (Owen, 2006. In Chile, retelling tasks are designed considering the structure of the verbal input, both on a lexical-syntactic and textual level, as well as setting levels of complexity among them (Pavez & Coloma, 2005. The research project FONDECYT 1130420 produced a storybook – as an input of a retelling task- emphasizing not only the verbal aspect, but also the visual narrative. Therefore, we set a double objective: to design narrative images of a story, enhancing its meaning through a visual grammar, and to observe how these elements were reflected in the oral retelling of the subjects. For this purpose, along with the Story Grammar (Glen & Stein, 1979 for the textual structure analysis, we used the Grammar of Visual Design (Kress & Van Leeuwen, 1996 as analytical tool for preparing narrative images. The story was piloted in a sample of 20 kindergarten children from a semiprivate school in the Region of Valparaiso. Their oral narratives were videotaped, transcribed and analyzed. It was noted that all narrative images were mentioned in more than 60% of the recounted version. In addition, three images were referred in 90% of the child narratives, representing key moments of the story or certain complexity of the narrative input as simultaneous actions. These results highlight the importance of the visual elements of a story for the task of child retelling.

    Background: Extracorporeal Shock Wave Lithotripsy (ESWL) is a non-invasive treatment of urinary stones which breaks them, by using externally applied, focused, high intensity acoustic pulse, into smaller pieces so that they can pass easily through ureter. Shock wave generation, focusing, coupling and stone localisation by fluoroscope or ultrasound are the basic components of ESWL. ESWL has some complications and is contraindicated in certain situations. The aim of this study was to evaluate the effectiveness and safety of ESWL in kidney and upper ureteric stones by Electromagnetic Lithotriptor. Methods: All adult patients with renal and upper ureteric stones having a diameter of up to 1 Cm were included in the study. Basic evaluation such as history, examination, ultrasound and excretory urography were performed. Electromagnetic lithotripsy was done and data were collected on a printed proforma from January 1, 2008 to March 30, 2009 in Institute of Kidney Diseases, Peshawar. Results: Out of a total of 625 patients 463 were male and 162 were female; 67.36% of patients were having renal stones, 23.84% upper ureteric and 8.8% both renal and ureteric stones. Complications noted were renal colic in 9.76%, haematuria in 3.2%, stein strasse in 2.72%, and fever in 1.12% of patients. The stone free rate was 89% and 7% of patients were having stone fragments <4 mm. ESWL failed in 4% of patients. Conclusion: ESWL is a safe and effective way of treating kidney and upper ureteric stones. (author)

  20. Housing Damage Following Earthquake

    An automobile lies crushed under the third story of this apartment building in the Marina District after the Oct. 17, 1989, Loma Prieta earthquake. The ground levels are no longer visible because of structural failure and sinking due to liquefaction. Sand and soil grains have faces that can cause friction as they roll and slide against each other, or even cause sticking and form small voids between grains. This complex behavior can cause soil to behave like a liquid under certain conditions such as earthquakes or when powders are handled in industrial processes. Mechanics of Granular Materials (MGM) experiments aboard the Space Shuttle use the microgravity of space to simulate this behavior under conditons that carnot be achieved in laboratory tests on Earth. MGM is shedding light on the behavior of fine-grain materials under low effective stresses. Applications include earthquake engineering, granular flow technologies (such as powder feed systems for pharmaceuticals and fertilizers), and terrestrial and planetary geology. Nine MGM specimens have flown on two Space Shuttle flights. Another three are scheduled to fly on STS-107. The principal investigator is Stein Sture of the University of Colorado at Boulder.
