    The objective of this program is to develop a synthesis gas conversion catalyst with higher selectivity to liquid fuels, while maintaining catalytic activity and stability at least equivalent relative to state-of-the-art precipitated iron catalysts. During this quarter, the emphasis in the program has been the investigation of the hydrocarbon cutoff hypothesis with supported ruthenium catalysts. An alumina-supported catalyst with smaller than 20[Angstrom] ruthenium particles was tested under conditions of maximal water gas shift activity. During this test more than 90% of the water made in the Fischer-Tropsch synthesis reaction was converted to H[sub 2]. However, the extent of ruthenium metal agglomeration was not reduced. Accordingly, it was not possible to conclude whether hydrocarbon cutoff occurs with smaller than 20[Angstrom] ruthenium particles on [gamma]-alumina. A ruthenium catalyst prepared on Y-type zeolite had 20[Angstrom] or smaller ruthenium particles according to STEM examination and a 15[Angstrom] average ruthenium metal particle size according to EXAFS examination. The ruthenium metal particle size was stable during the test with this catalyst. The hydrocarbon product distribution was Anderson-Schulz-Flory with no cutoff up to a carbon number of 160. A well-dispersed titania-supported ruthenium catalyst is going to be evaluated during the next quarter in order to determine whether hydrocarbon cutoff occurs.

    Full Text Available The study Masochisms. Mythologizing as an Aesthetics of Crisis in the Work of Bruno Schulz, parts of which have been translated below, presents the thesis that in the work of B. Schulz the phenomenon of mythologizing is connected with masochism – a concept conceived of as a historical, cultural and aesthetic interpretative category. The combination of the two phenomena makes it possible to notice some relationships between Schulz’s literary and graphic works which have not been recognized yet. The author discusses some psychoanalytical, sociological, historical and philosophical notions of masochism applicable to a literary text. She tries to describe the “masochistic aesthetics” appearing in Schulz’s short stories (on the narrative level: lack of motion, suspense, tension and in his graphics (theatricalization, lack of eye contact between the figures and shows how this aesthetics integrates the prose of Schulz, his Idolatrous Book and his illustrations for the short story The Book.

    The Schulze-Hardy rule suggests a strong dependence of the critical coagulation concentration (CCC) on the ionic valence. This rule is addressed theoretically and confronted with recent experimental results. The commonly presented derivation of this rule assumes symmetric electrolytes and highly charged particles. Both assumptions are incorrect. Symmetric electrolytes containing multivalent ions are hardly soluble, and experiments are normally carried out with the well-soluble salts of asymmetric electrolytes containing monovalent and multivalent ions. In this situation, however, the behavior is completely different whether the multivalent ions represent the counterions or co-ions. When these ions represent the counterions, meaning that the multivalent ions have the opposite sign than the charge of the particle, they adsorb strongly to the particles. Thereby, they progressively reduce the magnitude of the surface charge with increasing valence. In fact, this dependence of the charge density on the counterion valence is mainly responsible for the decrease of the CCC with the valence. In the co-ion case, where the multivalent ions have the same sign as the charge of the particle, the multivalent ions are repelled from the particles, and the surfaces remain highly charged. In this case, the inverse Schulze-Hardy rule normally applies, whereby the CCC varies inversely proportional to the co-ion valence.

    Full Text Available Os escritores Bruno Schulz e Joseph Roth entraram para a história da literatura, respectivamente, como representantes da literatura polonesa e austríaca, como se pertencessem a mundos diversos. Entretanto ambos compartilharam de uma memória comum, que era a vida nas províncias orientais do Império Austro-Húngaro, nas cidades de Drohobycz e Brody, hoje pertencentes à Ucrânia. As obras de ficção de Schulz e de Roth fazem referência ao universo austro-húngaro e habsburgo, um reino milenar que via a si mesmo não simplesmente como uma realidade política, mas como um império que tinha como missão trazer a seus súditos uma forma de vida considerada superior do ponto de vista espiritual, ético e moral. A idéia do Sacro Império Romano Germânico, que se considerava portador de uma mensagem humana, subsistiu, até o século 20, no longo reinado do Kaiser Francisco José e neste sentido a 1ª Guerra Mundial significa não simplesmente o desmembramento político do Império Austro-Húngaro em seus diferentes componentes, mas também a falência de uma idéia de Estado que transcendia à esfera do meramente político para tornar-se um lar espiritual e cultural para seus súditos. O mundo que sobreveio à 1ª Guerra Mundial é marcado pelas tendências fáustico-titânicas de um individualismo materialista, que devota todas suas energias à produção e à acumulação de capital, e é sobre este novo mundo que Schulz e Roth olham em suas obras, sempre do ponto de vista de um universo anterior, marcado pela nostalgia de um exílio irreversível. Palavras-chave: Nostalgia. Exílio. Império Habsburgo. Joseph Roth. Bruno Schulz. Bruno Schulz and Joseph Roth figure in the history of literature as Representatives of Polish and Austrian literature, respectively, as if they were part of different worlds.

    Ion specific effects on colloidal stability of titania nanosheets (TNS) were investigated in aqueous suspensions. The charge of the particles was varied by the pH of the solutions, therefore, the influence of mono- and multivalent anions on the charging and aggregation behavior could be studied when they were present either as counter or co-ions in the systems. The aggregation processes in the presence of inorganic salts were mainly driven by interparticle forces of electrostatic origin, however, chemical interactions between more complex ions and the surface led to additional attractive forces. The adsorption of anions significantly changed the surface charge properties and hence, the resistance of the TNS against salt-induced aggregation. On the basis of their ability in destabilization of the dispersions, the monovalent ions could be ordered according to the Hofmeister series in acidic solutions, where they act as counterions. However, the behavior of the biphosphate anion was atypical and its adsorption induced charge reversal of the particles. The multivalent anions destabilized the oppositely charged TNS more effectively and the aggregation processes followed the Schulze-Hardy rule. Only weak or negligible interactions were observed between the anions and the particles in alkaline suspensions, where the TNS possessed negative charge.

    Full Text Available Christian Norberg- Schulz explained his ideas about the phenomenology of architecture, indebted to Martin Heidegger’s opinionsand believed that one of the main strategies for identification of the place is creating meaningful environments. Schulz can be considered as one of theorists who created new ideas in architecture after Gideon and believed that considering to other scientific fields is necessary to achieve the true nature of architecture. In fact the phenomenological approach can be understood as an interdisciplinary species that explain about existence and cognition in other fields like designing different spaces. Accordingly emphasizing on interdisciplinary trends and studies can help to identify and understand the multiple issues and by studying the different approaches, the scientific expansion of the problem’s aspects will be possible. This article with an Interdisciplinary and phenomenological point of view and due to the main ideas of Norberg- Schulz, analyses the concept of place and space and also the importance of concerning about children’s spaces. So at first a brief knowledge about the book of Norberg-Schulz in phenomenological approach will be achieved and by studying the opinions of other theorists, some results about the importance of considering the concept of genius loci in architectural spaces will be achieved. In this document, by using the descriptive- analytical method and by means of data collection, including studies, library and documentation, the relating concepts and strategies of improving the quality of children’s spaces, is analyzed. According to this article, It could be said that meanings, culture and history of a place, include identifying factors that cause creating memories and a sense of belonging to the place for individuals and thus the formation of their personality in childhood. So one of the main tasks of modern architects is creating a sense of space in children’s spaces and reminding

    All records of the 15 hexactinellid sponge species known to occur off Chile are reviewed, including the first record in the Southeastern Pacific of the genus Caulophacus Schulze, 1885, with the new species Caulophacus chilense sp. n. collected as bycatch in the deep water fisheries of the Patagonian toothfish Dissostichus eleginoides Smitt, 1898 off Caldera (27ºS), Region of Atacama, northern Chile. All Chilean hexactinellid species occur in bathyal to abyssal depths (from 256 up to 4142 m); nine of them are reported for the Sala y Gomez and Nazca Ridges, with one species each in the Juan Fernandez Archipelago and Easter Island. The Chilean hexactinellid fauna is still largely unknown, consisting of only 2.5 % of the known hexactinellid extant species. Further studies and deep water sampling are essential to assess their ecology and distribution, particularly in northern Chile.

    Physalopterid nematodes identified as Heliconema longissimum (Ortlepp, 1923) were collected from the stomach of rice-paddy eels Pisodonophis boro (Hamilton) (Anguilliformes: Ophichthidae) from two brackish-water localities (mangroves) in Thailand: one in Phan-Nga Province, southwestern Thailand, northeast of Phuket Island, and one in Ranong Province, near the border with Myanmar. Study of the morphology of this hitherto insufficiently known nematode species, including its first SEM examination, enabled a detailed redescription of H. longissimum. Present taxonomic problems in the subfamily Proleptinae Schulz, 1927 are discussed, where a new delimitation of Proleptus Dujardin, 1845, Heliconema Travassos, 1919 and Paraleptus Wu, 1927 is proposed based on the cephalic dentation. H. minnanensis [sic] Damin & Heqing, 2001 is transferred to Paraleptus Wu, 1927 as P. minnanensis (Damin & Heqing, 2001) n. comb. and Paraleptus chiloscyllii Yin & Zhang, 1983 transferred by Damin & Heqing (2001) to Heliconema, is retained in Paraleptus. H. ahiri Karve, 1941 is considered a junior synonym of H. longissimum (Ortlepp, 1923). The present finding of H. longissimum in Pisodonophis boro represents the first host record and the first record of this nematode from Thailand.

    Nearly all previous evidence of the familial transmission of age at onset of schizophrenia has been in siblings and twins. In his paper, Bruno Schulz examined the age at onset distribution of schizophrenia in affected parent and offspring pairs, using a systematic series of ascertained cases (n = 106), as well as a second series of chronic in-patients (n = 36). The parent-offspring correlation in age at onset, for cases with a definite diagnosis in the systematically ascertained series, was estimated at 0.346 (95% confidence interval 0.134, 0.528). Schulz did not test for differences between the two series and between males and females, but our reanalysis, using correlational methods and a mixed linear model, did not detect any significant differences. These results are consistent with previous findings that age at onset of schizophrenia is influenced by familial factors which may be genetic.

    The ratio of divalent to monovalent ion concentration necessary to displace the surface-active protein, albumin, by lung surfactant monolayers and multilayers at an air-water interface scales as 2(-6), the same concentration dependence as the critical flocculation concentration (CFC) for colloids with a high surface potential. Confirming this analogy between competitive adsorption and colloid stability, polymer-induced depletion attraction and electrostatic potentials are additive in their effects; the range of the depletion attraction, twice the polymer radius of gyration, must be greater than the Debye length to have an effect on adsorption.

    Full Text Available Water Onion is an aquatic plant endemic to the coastal plains of southern Thailand. The species is listed as endangered on the IUCN Red List. Despite rapidly declining stocks, the species is not protected under any Thai legislation nor under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES. At the local level, Water Onion is protected and conserved by young people and adults for various socio-economic reasons. The study explored the participation and underlying conservation motivations of 312 youths in Kapoe district, Ranong province. Using principal component analysis, the youth's motivation for Water Onion conservation was classified into four categories: pro-social, pro-nature, social image, and extrinsic. The results from a logit regression indicated that pro-nature is one of the key motivational factors enhancing actual youth participation in the protection and conservation of Water Onion. It is important for policy makers to understand the effects of various types of motivation on different policy mechanisms in order to craft more effective policies that can further enhance youth participation in conservation initiatives.

    A new method is described for correcting experimental data obtained from the texture analysis of thin films. The analysis employed for correcting the data usually requires the experimental curves of defocalization for a randomly oriented specimen. In view of difficulties in finding non-oriented films, a theoretical method for these corrections is proposed which uses the defocalization evolution for a bulk sample, the film thickness and the penetration depth of the incident beam in the material. This correction method is applied to a film of YBa 2 CU 3 O 7-δ on an SrTiO 3 single-crystal substrate. (orig.)

    Full Text Available Though a clinical examination may reveal a deep fissure or pit on the surface of an anterior tooth, radiographic examination is a more accurate approach to diagnose an invagination. Dens invaginatus is one of the common dental deformities, but the defect involving the root and its association with radicular cyst is still very uncommon. The objective of this case presentation is to report a case of radicular dens in dente, which is a rare dental anomaly. This case report shows that dens invaginatus with an open apex and a radicular cyst can be treated successfully using currently available materials.

The article is a propaedeutic step to a wide long term authors' works research and can serve as a model for other similar studying, during which the issues of irrelation of kind and genre might occur. At the while studing the main objective is to explain the typological analysis of prose and poetry of these authors feasibility. After determining that the dominant in the analysis is the discourse of myth as a common reasoning of all works of both artists; and, based on the characteristics of the interwar two decades - a period when both Schulz and Antonych are the most active in their work, we conclude that the authors' texts fall into the mainstream of common European context (out of which we are mostly interested in Ukrainian and Polish aspects of the "expression of unutterable" that we consider the first evidence base of the subject comparative study. This concept stands first evidence base opportunities typological comparison of prose and poetry writers. The essence of the poetics of unutterable/ unspeakable lies in an attempt with the help of language and its expressive possibilities to sink in the ancient origins that in fact is the myth as a thought form and to define those things and concepts that are beyond human understanding, in subconsciousness. The second evidence base that allows us to compare lyric and epic works, is a significant presence of a literary diffusion phenomenon in the texts of both writers . Yet, all studies in this field have drawn attention to the genre diffusion within a literary kind until now. However, according to the specificity of B.I Antonych and B. Schultz works we are interested in class diffusion, which somewhat complicates finding a theoretical framework. Following the same way as the genre diffusion researchers, we turned to science and found interesting sub -kind of diffusion - ambipolar diffusion - simultaneous diffusion of opposite charged particles

We found that in the two treated groups the number of females recovered was significantly lower (P<0.05 than in the control group. 35, 70 and 117 females were recovered from the T1, T2 and C, respectively. The females obtained from the surviving larvae of the treated groups did not suffer any deleterious effects from the entomopathogen studied.

  12. ‘Winckelmann’s History of Art and Polykleitos’ from Warren G. Moon (ed., Polykleitos, the Doryphoros and Tradition, Madison, Wisconsin and London: The University of Wisconsin Press 1995

    Directory of Open Access Journals (Sweden)

    A. A. Donohue

    2010-06-01

    Full Text Available This essay is an expanded version of a paper delivered in 1989 at a colloquium organized around a replica of the Doryphorus acquired by the Minneapolis Institute of Arts. Winckelmann's treatment of Polyclitus serves to introduce a wider consideration of the structure and method of his history of classical art. It is argued that, contrary to assertions that he developed his history on the basis of his empirical observation of works of classical art, Winckelmann instead adopted historiographic schemata derived directly and indirectly from ancient authors. The ancient texts themselves reflect not so much authentic information about the visual arts as formulations from a tradition of histories of the ‘technai’, the arts of civilization, that were often linked with political history. Pliny's famous statement of the decline of art is re-interpreted in this light.

  10. The contribution of thermal radiation to the thermal conductivity of porous UO2

    International Nuclear Information System (INIS)

    Bakker, K.; Kwast, H.; Cordfunke, E.H.P.

    1994-09-01

    The influence of cylindrical, spherical and ellipsoidal inclusions on the overall thermal conductivity was computed with the finite element technique. The results of these calculations were compared with equations that describe the effect of inclusions on the overall thermal conductivity. The analytical equation of Schulz that describes the effect of inclusions on the overall thermal conductivity is in good agreement with the results of the finite element computations. This good agreement shows that among a variety of porosity correction formulas, the equation of Schulz gives the best description of the effect of inclusions on the overall thermal conductivity. This equation and the results of finite element calculations allow us to compute the contribution of radiation to the overall thermal conductivity of UO 2 with oblate ellipsoidal porosity. The present radiation calculations show that Hayes and Peddicord overestimated the contribution of thermal radiation to the thermal conductivity. (orig.)

    2006-01-01

    Viscometric measurements, in toluene solution at 30 deg C, were performed with high-cis polybutadiene synthesized by neodymium based catalyst. Six different equations were used to calculate intrinsic viscosities and viscosimetric constant values: Huggins, Kraemer, Martin and Schulz-Blaschke by graphic extrapolation, and Solomon-Ciuta, Deb-Chanterjee and again Schulz- Blaschke, through a single point determination. The molecular weight of the polymers was also determined applying Mark-Houwink-Sakurada equation using the values of intrinsic viscosity obtained by the six equations. The values of intrinsic viscosity and viscosity-average molecular weight obtained by the two methods were compared in order to verify the validity of the single point determination for high-cis polybutadiene.

    The primary initiatives of the LITCO Decontamination Development group at the Idaho Chemical Process Plant (ICPP) are the development of methods to eliminate the use of sodium bearing decontamination chemicals and minimization of the amount of secondary waste generated during decontamination activities. In July of 1994, a Commerce Business Daily (CBD) announcement was issued by the INEL to determine commercial interest in the development of an in-situ liquid abrasive grit blasting system. As a result of the CBD announcement, Klieber ampersand Schulz issued an Expression of Interest letter which stated they would be interested in testing a prototype Liquid Abrasive Pressure Pot (LAPP). LITCO's Decontamination group and Kleiber ampersand Schulz entered into a Cooperative Research and Development Agreement (CRADA) in which the Decontamination Development group tested the prototype LAPP in a non-radioactive hot cell mockup.

    2007-01-01

    The polishing phenomenon of road pavements under the vehicle traffic constitutes the main mechanism inherent to the loss of skid resistance over time. A better understanding of this phenomenon would allow an improvement of road safety. This study comprises a review of laboratory test and a model simulating the polishing of road surfaces. The laboratory test uses a polishing machine so called 'Wehner-Schulze' which can reproduce the evolution of the road texture from specimens taken directly f...

    Public information campaigns have played an important role in increasing awareness of organ donation and the need for more organ donors. In a recent study, it was found that awareness and knowledge, regarding organ donation, represented only two of several factors in people’s decisions to engage in organ donation-related behaviors (Schulz et al., 2006). In addition, it was noted that the three main language groups in Switzerland differ substantially with respect to the influential factors ...

    Full Text Available Much remote sensing (RS research focuses on fusing, i.e., combining, multi-resolution/multi-sensor imagery for land use/land cover (LULC classification. In relation to this topic, Sun and Schulz [1] recently found that a combination of visible-to-near infrared (VNIR; 30 m spatial resolution and thermal infrared (TIR; 100–120 m spatial resolution Landsat data led to more accurate LULC classification. They also found that using multi-temporal TIR data alone for classification resulted in comparable (and in some cases higher classification accuracies to the use of multi-temporal VNIR data, which contrasts with the findings of other recent research [2]. This discrepancy, and the generally very high LULC accuracies achieved by Sun and Schulz (up to 99.2% overall accuracy for a combined VNIR/TIR classification result, can likely be explained by their use of an accuracy assessment procedure which does not take into account the multi-resolution nature of the data. Sun and Schulz used 10-fold cross-validation for accuracy assessment, which is not necessarily inappropriate for RS accuracy assessment in general. However, here it is shown that the typical pixel-based cross-validation approach results in non-independent training and validation data sets when the lower spatial resolution TIR images are used for classification, which causes classification accuracy to be overestimated.

  8. The contribution of thermal radiation to the thermal conductivity of porous UO2

    International Nuclear Information System (INIS)

    Bakker, K.; Kwast, H.; Cordfunke, E.H.P.

    1995-01-01

    The influence of cylindrical, spherical and ellipsoidal inclusions on the overall thermal conductivity was computed with the finite element technique. The results of these calculations were compared with equations that describe the effect of inclusions on the overall thermal conductivity. The analytical equation of Schulz [B. Schulz, KfK-1988 (1974)] that describes the effect of inclusions on the overall thermal conductivity is in good agreement with the results of the finite element computations. This good agreement shows that among a variety of porosity correction formulas, the equation of Schulz gives the best description of the effect of inclusions on the overall thermal conductivity. This equation and the results of finite element calculations allow us to compute the contribution of radiation to the overall thermal conductivity of UO 2 with oblate ellipsoidal porosity. The present radiation calculations show that Hayes and Peddicord [S.L. Hayes and K.L. Peddicord, J. Nucl. Mater. 202 (1993) 87] overestimated the contribution of thermal radiation to the thermal conductivity. ((orig.))

    Cuticles have been macerated from suitably preserved compressed fossil foliage by Schulze's process for the past 150 years, whereas the physical-biochemical relationship between the "coalified layer" with preserved cuticle as a unit has hardly been investigated, although they provide complementary information. This relationship is conceptualized by an analogue model of the anatomy of an extant leaf: "vitrinite (mesophyll) + cuticle (biomacropolymer) = compression". Alkaline solutions from Schulze's process as a proxy for the vitrinite, are studied by means of liquid-solid states Fourier transform infrared spectroscopy (FTIR). In addition, cuticle-free coalified layers and fossilized cuticles of seed ferns mainly from Canada, Spain and Argentina of Late Pennsylvanian-Late Triassic age are included in the study sample. Infrared data of cuticle and alkaline solutions differ which is primarily contingent on the mesophyll +biomacropolymer characteristics. The compression records two pathways of organic matter transformation. One is the vitrinized component that reflects the diagenetic-post-diagenetic coalification history parallel with the evolution of the associated coal seam. The other is the cuticle that reflects the sum-total of evolutionary pathway of the biomacropolymer, its monomeric, or polymeric fragmentation, though factors promoting preservation include entombing clay minerals and lower pH conditions. Caution is advised when interpreting liquid-state-based FTIR data, as some IR signals may have resulted from the interaction of Schulze's process with the cuticular biochemistry. A biochemical-study course for taphonomy is suggested, as fossilized cuticles, cuticle-free coalified layers, and compressions are responses to shared physicogeochemical factors. ?? 2009 Elsevier B.V.

    2013-01-01

    A non-commutative formula for the isotropic magneto-electric response of disordered insulators under magnetic fields is derived using the methods of non-commutative geometry. Our result follows from an explicit evaluation of the Ito derivative with respect to the magnetic field of the non-commutative formula for the electric polarization reported in Schulz-Baldes and Teufel (2012 arXiv:1201.4812v1). The quantization, topological invariance and connection to a second Chern number of the magneto-electric response are discussed in the context of three-dimensional, disordered, time-reversal or inversion symmetric topological insulators.

Then we argue that by simply promoting wavenumbers to wave vectors we are able to study the two dimensional case.

    A series of iron catalysts were prepared on three different types of supports: alumina and two activated carbons from eucalyptus woods and tagua seeds. Potassium was used as promoter and palladium was deposited by the excess wetness impregnation method. The catalysts were characterized by N 2 adsorption at 77 K, XRD and TPR analysis and evaluated as Fischer-Tropsch catalysts. The carbon supported catalysts favour the production of liquid hydrocarbons and decrease the aqueous phase. Those supported with alumina form gases and aqueous phase as the main products. The α p parameters of the Schulz-Flory distribution show hydrocarbons between gasoline and diesel

    Full Text Available We address the issue of approximating the pseudoinverse of the coefficient matrix for dynamically building preconditioning strategies for the numerical solution of large dense linear least-squares problems. The new preconditioning strategies are embedded into simple and well-known iterative schemes that avoid the use of the, usually ill-conditioned, normal equations. We analyze a scheme to approximate the pseudoinverse, based on Schulz iterative method, and also different iterative schemes, based on extensions of Richardson's method, and the conjugate gradient method, that are suitable for preconditioning strategies. We present preliminary numerical results to illustrate the advantages of the proposed schemes.

    2013-01-01

    Drawing from Heckhausen and Schulz's Motivational Theory of Life-span Development, this study examined perceived control as a moderator of the protective relationship between downward social comparison and subjective well-being among older adults. Community-dwelling older adults (N = 97, 63% female, ages 79-97) were interviewed in their own homes at three time-points over a nine-year period. Interviews assessed older adults' perceived control over daily tasks, their use of downward social comparison in response to task restriction, and their subjective well-being. Regression analyses yielded a significant interaction between downward social comparison and perceived control for three subjective well-being outcomes: life satisfaction, perceived stress, and depressive symptoms. Follow-up analyses revealed that downward social comparison was associated with greater subjective well-being at low levels of perceived control; but was unrelated to subjective well-being at high levels of perceived control. These findings corroborate Heckhausen and Schulz's theorized goal-opportunity congruence premise and have implications for quality-of-life interventions to assist community-dwelling older adults.

Franz Kafka and Bruno Schulz – two classics of modernity, residents of “Republic of dreams”, if to use a beautiful metaphor of Schultz, were from Jewish families lived in a multicultural and multilingual Austro-Hungarian Empire absorbed with best achievements of the Austrian culture. As noted by J. Updike: «Kafka and Schulz – two unremarkable man, born in the backyard of once powerful empire, took a bite at the same apple myth, but from different sides». Both were able to transform the insightful observation in prophecy, describing the dreams and nightmares as precisely as if they were facts of life, both shed light on human nature and witnessed history, complementing each other. I. Klekh rightly observes certain «commonness» of their creative method, stressing the importance for the two writers’ motif of transformation, transformation, mutual penetration of books and worlds. Shulz’s «fairy tale», his myth-making, guided by its own laws, “mythological” rules, which, unlike Kafka, is not «mythological» of closeness exclusively on internal self-perception.

    Calculated results are presented for the solution of a very strong shock tube problem on a coarse mesh using (1) MESA code, (2) UNICORN code, (3) Schulz hydro, and (4) modified TVD scheme. The first two codes are written in Eulerian coordinates, whereas methods (3) and (4) are in Lagrangian coordinates. MESA and UNICORN codes are both of second order and use different monotonic advection method to avoid the Gibbs phenomena. Code (3) uses typical artificial viscosity for inviscid flow, whereas code (4) uses a modified TVD scheme. The test problem is a strong shock tube problem with a pressure ratio of 109 and density ratio of 103 in an ideal gas. For no mass-matching case, Schulz hydro is better than TVD scheme. In the case of mass-matching, there is no difference between them. MESA and UNICORN results are nearly the same. However, the computed positions such as the contact discontinuity (i.e. the material interface) are not as accurate as the Lagrangian methods.

  16. ‘You think your writing belongs to you?’: Intertextuality in Contemporary Jewish Post-Holocaust Literature

    Directory of Open Access Journals (Sweden)

    2018-03-01

    Full Text Available This article examines a sub-category of recent Jewish post-Holocaust fiction that engages with the absent memory of the persecution its authors did not personally witness through the medium of intertextuality, but with intertextual recourse not to testimonial writing but to literature only unwittingly or retrospectively shadowed by the Holocaust. It will be proposed that this practice of intertextuality constitutes a response to the post-Holocaust Jewish author’s ‘anxiety of influence’ that, in the wake of the first generation’s experience of atrocity, their own life story and literature will always appear derivative. With reference to works by four such post-Holocaust authors, Jonathan Safran Foer’s Tree of Codes (2010, Maxim Biller’s Im Kopf von Bruno Schulz (2013, Helen Maryles Shankman’s In the Land of Armadillos (2016, and Nicole Krauss’s The History of Love (2005 and Forest Dark (2017, all of which engage intertextually with Franz Kafka and Bruno Schulz, it will be suggested that these authors are looking to return to a Kristevan practice of intertextuality after the predominantly citational recourse to antecedent material that has often characterized post-Holocaust literature. In the process, they also succeed in troubling recently popular conceptualizations of ‘postmemory’ literature as the ‘belated’ and ‘evacuated’ recipient of encrypted traumatic content inherited from the first generation that it must now seek either to preserve or to work through vicariously.

    For the co-fermentation of organic waste and sewage sludge in digester towers at municipal sewage treatment plant, mainly single-stage processes have so far been studied or are in use in part. Within the framework of a project sponsored by the foundation Oswald-Schulze-Stiftung, the use of a two-stage mode of operation (thermophilic/mesophilic) for co-fermenting organic waste and sewage sludge was investigated. By adding organic waste to the digester content, biogas production per reactor volume was more than doubled in comparison with exclusive sewage sludge fermentation. Because of the thermophilic stage for the conditioning of organic waste, specific biogas yield for an organic load of 1.5 kg organic dry residue TR/m{sup 3*}d was slightly enhanced in comparison with single-stage co-fermentation.

    Full Text Available This paper reports on the outcomes of an exploratory narrative study on the impact of participatory music making on social determinants of health (SDOH and wellbeing for refugees in Brisbane, Australia. A key component of this exploratory research was to map health and wellbeing outcomes of music participation using an existing SDOH framework developed by researchers in the field of health promotion (Schulz & Northridge, 2004. This paper maps reported health and wellbeing outcomes for five refugee and asylum seeker members of a participatory Brisbane-based music initiative, the Scattered People, along an SDOH continuum ranging from individual level through to macro level fundamental determinants of health.While most themes emerging from this study corresponded to distinct categories in the Schulz and Northridge SDOH framework, three key aspects, which were critical to the achievement of wellbeing for participants, did not fit any of the pre-defined categories. These were: cultural expression, music making, and consolidation of personal and social identity. The importance of those themes to participants suggests that music and wellbeing studies involving culturally diverse groups and from a SDOH perspective may need to consider broader, more relevant concepts. The paper provides recommendations for future interdisciplinary research in this field.

    Full Text Available Foram realizadas medidas viscosimétricas, em soluções de tolueno e ciclo-hexano, a 30°C, com polibutadieno alto-cis, sintetizado com catalisadores à base de neodímio. Foram empregadas diferentes equações para determinar os valores de viscosidade intrínseca: Huggins; Kraemer; Martin; e Schulz-Blaschke, por extrapolação gráfica; e Solomon-Ciuta; Deb-Chanterjee e; novamente, Schulz-Blaschke, por determinação por um único ponto. Os valores de viscosidade intrínseca obtidos pelos dois métodos (extrapolação gráfica e por um único ponto foram comparados a fim de se verificar a validade da determinação por um único ponto para os sistemas analisados, bem como determinar que equação fosse a mais adequada para esse tipo de cálculo. Foram calculadas as constantes viscosimétricas de Huggins, Kraemer e Schulz-Blaschke e foi feita uma análise da qualidade do solvente, levando-se em conta também os valores do parâmetro de solubilidade de Hildebrand dos solventes e do polímero. Foi determinada a distância média quadrática entre as extremidades das cadeias poliméricas por meio da equação de Flory, para tal foram utilizados os dados viscosimétricos obtidos, bem como os pesos moleculares determinados por viscosimetria e por cromatografia de exclusão por tamanho. Verificou-se que o método de determinação por um único ponto foi apropriado para o polibutadieno alto-cis, tanto para o cálculo de viscosidade intrínseca quanto de peso molecular. Em tolueno, a equação de Solomon-Ciuta foi a mais adequada, ao passo que a equação de Deb-Chanterjee foi mais apropriada para o polímero em ciclo-hexano. Verificou-se também que o tolueno foi o melhor solvente para o polibutadieno em função dos maiores valores de viscosidade intrínseca e de distância média quadrática entre os extremos da cadeia polimérica. Os valores obtidos para as constantes viscosimétricas confirmaram essa observação.Viscometric measurements, in

    Full Text Available Schmallenberg virus affects ruminants, which causes significant economic losses.  The virus is transmitted through vectors of the genus Culicoides; however, other studies do not rule out the possibility of sexual transmission due to its presence in semen. For this reason, the National Service of Animal Health of Costa Rica (SENASA imposed restrictions on the import of semen from animals from the European Union in 2013. Consequently, SENASA conducted a study to determine the presence or absence of antibodies against this virus in bovine, ovine and caprine samples. As a result, no antibodies against this virus were detected in the 748 samples tested. It was concluded that Schmallenberg virus was not circulating in Costa Rican ruminants during the tested period.

  1. A critical review on the scaling theory of dispersion

    The phenomenon of dispersive mixing of solutes in aquifers is subject of research since decades. The characterization of dispersivity at a particular field site is a prerequisite to predict the movement and spreading of a contaminant plume. Experimental investigations have shown, that field-scale dispersivities vary over orders of magnitude, which apparently depends on the scale of measurement. Gelhar et al. [1992] and Schulze-Makuch [2005] have reviewed a large number of transport experiments reported in the literature. Based on that data Schulze-Makuch [2005] performed a trend analysis of longitudinal dispersivity, fostering the empirical relationship of a power law between dispersivities and the scale of measurement without an upper bound. The goal of our study is to critically revisit not only the data used for the trend analysis but the power-law scale dependence of longitudinal dispersivity (e.g. Neuman [1990], Xu and Eckstein [1995]). Our particular focus is on the reported dispersivities of large amount (larger than 100m) and large measurement scales (in the order of kilometers). We aim to evaluate current theories of transport against a critical "mass" of field experiments and to bracket the conditions of their applicability. We further aim to evaluate the adequacy of the field sampling techniques that were employed from the perspective of more than 30 years development in modeling and field characterization. Given the tremendous progress in field data acquisition techniques and new insights gained, it is reasonable to expect that interpretations of past experiments may be flawed due to the limitations or inadequacy of field sampling techniques.

    Hyalomma Koch, 1844 are ixodid ticks that infest mammals, birds and reptiles, to which 27 recognized species occur across the Afrotropical, Palearctic and Oriental regions. Despite their medical and veterinary importance, the evolutionary history of the group is enigmatic. To investigate various taxonomic hypotheses based on morphology, and also some of the mechanisms involved in the diversification of the genus, we sequenced and analysed data derived from two mtDNA fragments, three nuclear DNA genes and 47 morphological characters. Bayesian and Parsimony analyses based on the combined data (2242 characters for 84 taxa) provided maximum resolution and strongly supported the monophyly of Hyalomma and the subgenus Euhyalomma Filippova, 1984 (including H. punt Hoogstraal, Kaiser and Pedersen, 1969). A predicted close evolutionary association was found between morphologically similar H. dromedarii Koch, 1844, H. somalicum Tonelli Rondelli, 1935, H. impeltatum Schulze and Schlottke, 1929 and H. punt, and together they form a sister lineage to H. asiaticum Schulze and Schlottke, 1929, H. schulzei Olenev, 1931 and H. scupense Schulze, 1919. Congruent with morphological suggestions, H. anatolicum Koch, 1844, H. excavatum Koch, 1844 and H. lusitanicum Koch, 1844 form a clade and so also H. glabrum Delpy, 1949, H. marginatum Koch, 1844, H. turanicum Pomerantzev, 1946 and H. rufipes Koch, 1844. Wide scale continental sampling revealed cryptic divergences within African H. truncatum Koch, 1844 and H. rufipes and suggested that the taxonomy of these lineages is in need of a revision. The most basal lineages in Hyalomma represent taxa currently confined to Eurasia and molecular clock estimates suggest that members of the genus started to diverge approximately 36.25 million years ago (Mya). The early diversification event coincides well with the collision of the Indian and Eurasian Plates, an event that was also characterized by large scale faunal turnover in the region. Using S

    Schulz, T. F.

    2007-01-01

    In this dissertation by Thorsten Frank Schulz the intermediate steps necessary to realise the 2000-Watt Society in Switzerland are examined. An analysis of an energy-economic scenario shows that the 2000-Watt Society should be seen as a long-term goal. According to the author, the major changes required to allow the implementation of this project concern energy-transformation and energy-demand technologies. Electricity will, according to the author, play an important role in a service-oriented society in the future. In such a transformation even intermediate steps are associated with considerable expense. The aims of the 2000-Watt Society project are listed. Energy and CO 2 balances for the domestic and transport sectors are presented and discussed. Complementary analyses are presented concerning fuel cells and wood-based fuel technologies. Finally, the implications of the 2000-Watt society and the effects of technological change are summarised and an outlook is presented

  5. Topological quantization of ensemble averages

    Prodan, Emil

    2009-01-01

    We define the current of a quantum observable and, under well-defined conditions, we connect its ensemble average to the index of a Fredholm operator. The present work builds on a formalism developed by Kellendonk and Schulz-Baldes (2004 J. Funct. Anal. 209 388) to study the quantization of edge currents for continuous magnetic Schroedinger operators. The generalization given here may be a useful tool to scientists looking for novel manifestations of the topological quantization. As a new application, we show that the differential conductance of atomic wires is given by the index of a certain operator. We also comment on how the formalism can be used to probe the existence of edge states

    The Green Flight Challenge is one of the National Aeronautics and Space Administration s Centennial Challenges designed to push technology and make passenger aircraft more efficient. Airliners currently average around 50 passenger-miles per gallon and this competition will push teams to greater than 200 passenger-miles per gallon. The aircraft must also fly at least 100 miles per hour for 200 miles. The total prize money for this competition is $1.65 Million. The Green Flight Challenge will be run by the Comparative Aircraft Flight Efficiency (CAFE) Foundation September 25 October 1, 2011 at Charles M. Schulz Sonoma County Airport in California. Thirteen custom aircraft were developed with electric, bio-diesel, and other bio-fuel engines. The aircraft are using various technologies to improve aerodynamic, propulsion, and structural efficiency. This paper will explore the feasibility of the rule set, competitor vehicles, design approaches, and technologies used.

  7. Fluctuations of Wigner-type random matrices associated with symmetric spaces of class DIII and CI

    Stolz, Michael

    2018-02-01

    Wigner-type randomizations of the tangent spaces of classical symmetric spaces can be thought of as ordinary Wigner matrices on which additional symmetries have been imposed. In particular, they fall within the scope of a framework, due to Schenker and Schulz-Baldes, for the study of fluctuations of Wigner matrices with additional dependencies among their entries. In this contribution, we complement the results of these authors by explicit calculations of the asymptotic covariances for symmetry classes DIII and CI and thus obtain explicit CLTs for these classes. On the technical level, the present work is an exercise in controlling the cumulative effect of systematically occurring sign factors in an involved sum of products by setting up a suitable combinatorial model for the summands. This aspect may be of independent interest. Research supported by Deutsche Forschungsgemeinschaft (DFG) via SFB 878.

    A simple method, considering a parallel beam approximation has been made to reproduce the main features of the defocusing effect, observed when pole figures are measured with the Schulz reflection technique using X-ray diffraction. A Lorentzian curve was used to approximate the primary beam profile. This method applied to low index reflections of copper and silver shows qualitatively and partially quantitatively, the extent the elongation of the ellipse resulting from the intersection of the beam with the tilted sample causes the defocusing effect. Differences observed experimentally are attributed mainly to the divergence of the beam, but also partially to the particular primary beam profile. Additionally, measurements with two different vertical heights of the receiving slit, i. e. the measured arch length of the Debye-Scherrer ring, indicate that this parameter plays no role in defocusing.

    Löckenhoff, Corinna E

    2012-09-01

    The impending retirement of large population cohorts creates a pressing need for practical interventions to optimize outcomes at the individual and societal level. This necessitates comprehensive theoretical models that acknowledge the multi-layered nature of the retirement process and shed light on the dynamic mechanisms that drive longitudinal patterns of adjustment. The present commentary highlights ways in which contemporary life-span developmental frameworks can inform retirement research, drawing on the specific examples of Bronfenbrenner's Ecological Model, Baltes and Baltes Selective Optimization with Compensation Framework, Schulz and Heckhausen's Motivational Theory of Life-Span Development, and Carstensen's Socioemotional Selectivity Theory. Ultimately, a life-span developmental perspective on retirement offers not only new interpretations of known phenomena but may also help to identify novel directions for future research as well as promising pathways for interventions.

    2015-06-01

    Full Text Available Archaeologists have long wondered about the Temple of Abu Simbel: its location within the Nubian territory far from major Egyptian cities, and its unique design. Utilizing the hermeneutic process of understanding the whole from the parts and then situating the whole within a bigger whole (context, this study is a trial to arrive at a better interpretation of this monument. Drawing on the characteristic analysis of the temple's Genius Loci as developed by Norberg-Schulz, as well as on Heidegger's anticipatory fore-structures, the study goes on to show that both of the location and the unique structure of the temple were the outcome of political and conceptual aspects of the period, more than being a religious tradition. Reaching this conclusion, another goal had been achieved, where the validity of hermeneutic analyses as a useful tool for discovering new dimensions about historical monuments and archaeological sites had been attested.

    The 1s (2s)2:2S Schulz resonance of He(-) is investigated theoretically, applying the full projection-operator formalism developed by Temkin and Bhatia (1985) in a Rayleigh-Ritz variational calculation. The technique is described in detail, and results for five different approximations of the He target state are presented in a table. Good convergence is obtained, but it is found that even the best calculated value of the resonance is about 130 meV higher than the experimentally measured value of 19.367 + or - 0.007 eV (Brunt et al., 1977), a discrepancy attributed to the contribution of the shift in the Feshbach formalism.

    Thermal and catalytic steam reforming of oil shale mined from Leningrad and Kashpir deposits was studied. Experiments were performed in fixed bed reactor by varying temperature and steam flow rate. Data obtained were approximated by empirical formulas containing some parameters calculated by least-squares method. Thus predicting amount of hydrogen, carbon monoxide and methane in producer gas is possible for given particular kind of oil shale, temperature and steam flow rate. Adding Ni catalyst enriches hydrogen and depletes CO content in effluent gas at low gasification temperatures. Modeling gas simulating steam reforming gases (H{sub 2}, CO, CO{sub 2}, and N{sub 2} mixture) was tested in hydrocarbon synthesis over Co-containing supported catalyst. Selectivity of CO conversion into C{sub 5+} hydrocarbons reaches 84% while selectivity to methane is 7%. Molecular weight distribution of synthesized alkanes obeys Anderson-Schulz-Flory equation and chain growth probability 0.84. (orig.)

    The spatial valence electron distribution in silicon and diamond is calculated in adiabatic bond charge approximation at zero temperature when bond charges have the Gaussian shape and their tensor character is taken into account. An agreement between theory and experiment has been achieved. For this purpose Xia's ionic pseudopotentials and Schulze-Unger's dielectric function are used. By two additional parameters Asub(B) and Zsub(B)sup(') we describe the spatial extent of the bond charge and local-field corrections, respectively. The parameter Zsub(B)sup(') accounts for the ratio between the Coulomb and exchange correlation interactions of the valence electrons and its silicon and diamond values have different signs.

The focus on legal order within the practices of Sociology of Law and Criminology is pivotal in order to reframe terrorism within a viable SPM. In “The Counterterrorism Handbook”, written by Bolz, Dudonis, and Schulz (2005, terrorism, at its very basic level, is defined as “an action that the urban guerrilla must execute with the greatest cold bloodedness, calmness and decision”. They further go on to provide a more scholarly definition: “the calculated use of violence to attain goals which are political, religious or ideological in nature. Terrorism involves a criminal act that is often symbolic in nature and intended to influence an audience beyond the immediate victims”.

    A recent experimental [P. Karageorgiev, D. Neher, B. Schulz, B. Stiller, U. Pietsch, M. Giersig, L. Brehmer, Nature Mater. 4, 699 (2005)] study has found liquidlike diffusion below the glass-transition temperature in azobenzene-containing materials under irradiation. This result suggests that the isomerization-induced massive mass transport that leads to surface relief gratings formation in these materials, is induced by this huge increase of the matrix diffusion coefficient around the probe. In order to investigate the microscopic origin of the increase of the diffusion, we use molecular dynamics simulations of the photoisomerization of probe dispersed red 1 molecules dispersed inside a glassy molecular matrix. Results show that the increased diffusion is due to an isomerization-induced cage-breaking process. A process that explains the induced cooperative motions recently observed in these photoactive materials.

  17. Intermediate steps towards the 2000-Watt society in Switzerland: an energy-economic scenario analysis[Dissertation 17314

    Schulz, T. F

    2007-07-01

    In this dissertation by Thorsten Frank Schulz the intermediate steps necessary to realise the 2000-Watt Society in Switzerland are examined. An analysis of an energy-economic scenario shows that the 2000-Watt Society should be seen as a long-term goal. According to the author, the major changes required to allow the implementation of this project concern energy-transformation and energy-demand technologies. Electricity will, according to the author, play an important role in a service-oriented society in the future. In such a transformation even intermediate steps are associated with considerable expense. The aims of the 2000-Watt Society project are listed. Energy and CO{sub 2} balances for the domestic and transport sectors are presented and discussed. Complementary analyses are presented concerning fuel cells and wood-based fuel technologies. Finally, the implications of the 2000-Watt society and the effects of technological change are summarised and an outlook is presented.

    Coagulation experiments are accomplished to identify the geochemical conditions for the stability of Febex bentonite colloids in granite ground water. The experiments are carried out by varying pH, ionic strength and type of electrolyte. The dynamic light scattering technique (photon correlation spectroscopy) is used to measure the size evolution of the colloids with time. Agglomeration rates are higher in MgCl{sub 2} and CaCl{sub 2} than in NaCl solution. Relative agglomeration rates follow approximately the Schulze-Hardy rule. Increasing agglomeration rates at pH>8 are observed in experiments with MgCl{sub 2} and CaCl{sub 2} which are, however, caused by coprecipitation phenomena. Bentonite colloid stability fields derived from the colloid agglomeration experiments predict low colloid stabilization in granite ground water taken from Aespoe, Sweden, and relatively high colloid stability in Grimsel ground water (Switzerland)

    The demands of a career in competitive sports can lead to chronic stress perception among athletes if there is a non-conformity of requirements and available coping resources. The Trier Inventory for Chronic Stress (TICS) (Schulz et al., 2004) is said to be thoroughly validated. Nevertheless, it has not yet been subjected to a confirmatory factor analysis. The present study aims (1) to evaluate the factorial validity of the TICS within the context of competitive sports and (2) to adapt a short version (TICS-36). The total sample consisted of 564 athletes (age in years: M = 19.1, SD = 3.70). The factor structure of the original TICS did not adequately fit the present data, whereas the short version presented a satisfactory fit. The results indicate that the TICS-36 is an economical instrument for gathering interpretable information about chronic stress. For assessment in competitive sports with TICS-36, we generated overall and gender-specific norm values. PMID:29593611

    Results for the lowest (Schulz) autodetaching state of He - [1s(2s) 2 ] are reported. The calculation utilizes the full projection-operator formalism as explicitly developed by Temkin and Bhatia [Phys. Rev. A 31, 1259 (1985)]. Eigenvalues, scrE = , are calculated using projection operators Q depending on increasingly elaborate target wave functions going up to a 10-term Hylleraas-form, and a configuration-interaction total wave function Phi of 40 configurations. Results are well converged, but our best value is --0.13 eV above the experimental position at 19.37 eV. We conclude that the shift (Δ) in the Feshbach formalism gives a large contribution (relative to the width) to the position E/sub r/ ( = scrE+Δ). An appendix is devoted to the evaluation of the most complicated type of three-center integral involved in the calculation

    2009-12-01

    Full Text Available In Political Romanticism, a work from 1919, Carl Schmitt interprets German romanticism as a “metaphysic” in which aesthetic concepts become the guiding concepts of all human activity. On this basis, he analyses and criticizes the effects of the expansion of aesthetic concerns on political action. This essay reconstructs Schmitt’s argument as a conceptual-historical genealogy of a modern discursive formation from which, as a by-product, a form of subjectivity now present in advanced capitalist societies was constituted. By contrasting Schmitt’s concept of the political in Political Romanticism with various works of contemporary sociology (Boltanski, Lipovetsky, Schulze, the article concludes by pointing out the political phenomena that are linked to the diffusion of this type of subjectivity.

  4. Study of the ion density of a radio-frequency plasma using electrostatic probes and focussed microwave interferometers

    Nguyen Cao, L.; Gagne, R.R.J.

    1976-01-01

    In order to verify experimentally and compare recent ion theories for cylindrical electrostatic probes, the ion density in a radio-frequency plasma was evaluated from V-I curves by means of six different theories. At low pressures, the theories of Bernstein and Rabinowitz, of Lam and Laframboise, give values of density which differ respectively by 20, 25 and 30% compared with the values obtained using a 10GHz focussed microwave interferometer. At the continuum limit, The Schulz and Brown's, and Su and Kiel's theories give density values which disagree respectively by 55 and 20%, compared with the values obtained by microwaves. For pressures varying from 0.05 to 3mmHg, the decrease of ion current, as predicted theorically by Waymouth, was observed. The density perturbation near the probe was found to be a dominant factor affecting the precision of density measurements, for pressures up to 2mmHg at least for our experimental conditions [fr

    The roundtable discussion began with remarks by the chairman who pointed out the complicated nature of plutonium chemistry. Judging from the papers presented at this symposium, he noticed a pattern which indicated to him the result of diminished funding for investigation of basic plutonium chemistry and funding focused on certain problem areas. Dr. G.L. silver pointed to plutonium chemists' erroneous use of a simplified summary equation involving the disproportionation of Pu(EV) and their each of appreciation of alpha coefficients. To his appreciation of alpha coefficients. To his charges, Dr. J.T. Bell spoke in defense of the chemists. This discussion was followed by W.W. Schulz's comments on the need for experimental work to determine solubility data for plutonium in its various oxidation states under geologic repository conditions. Discussion then turned to plutonium pyrachemical process with Dana C. Christensen as the main speaker. This paper presents edited versions of participants' written version

    As organic matter (OM) is readily mineralized to carbon dioxide (Smith and Hollibangh, 1993; Emerson and Hedges, 2002; Szymczycha et al., 2017) it has a direct link to the carbon dioxide abundance in seawater and an indirect influence on the carbon dioxide concentration in the atmosphere (Emerson and Hedges, 2002; Schulz and Zabel, 2006). OM is a quantitatively minor yet important component of seawater. OM in seawater can originate from internal sources (marine, or planktonic, or autochthonous OM) or external sources (terrestrial, or allochtonous OM) (Maksymowska et al., 2000; Emerson and Hedges, 2002; Turnewitsch et al., 2007; Arndt et al., 2013). It is commonly divided into two fractions: dissolved (DOM) and particulate (POM). Organic carbon (OC) is, most often, used as a measure of OM.

    Only 13 years after realizing, during a repair of a telegraph cable pulled out from the deep sea, that the depth of the ocean is plentifully populated with a highly diverse fauna and flora, the Challenger expedition (1873-1876) treasured up a rich collection of vitreous sponges (Hexactinellida). They had been described by Schulze and represent the phylogenetically oldest class of siliceous sponges (phylum Porifera); they are eye-catching because of their distinct body plan, which relies on a filigree skeleton. It is constructed by an array of morphologically determined elements, the spicules. Soon after, during the German Deep Sea Expedition "Valdivia" (1898-1899), Schulze could describe the largest siliceous hexactinellid sponge on Earth, the up to 3-m high Monorhaphis chuni, which develops the equally largest bio-silica structure, the giant basal spicules (3 mx10 mm). Using these spicules as a model, basic knowledge on the morphology, formation, and development of the skeletal elements could be achieved. They are formed by a proteinaceous scaffold (composed of a 27-kDa protein), which mediates the formation of the siliceous lamellae, into which the proteins are encased. The high number of 800 of 5-10 microm thick lamellae is concentrically arranged around the axial canal.

  13. Holocene Millennial Time Scale Hydrological Changes In Central-east Africa

    Jolly, D.; Bonnefille, R.; Beaufort, L.

    The Holocene hydrological changes of a tropical swamp is reconstructed using a high resolution pollen record (ca 50 yrs) from the Kuruyange valley (Burundi, Africa, 3°35'S, 29°41'E), at 2000 m elevation. The sequence was dated by 10 radiocarbon dates, allowing reconstruction between ca 12 500 and 1000 cal yr B.P. In the Kuruyange swamp, peat accumulated rapidly at a sedimentation rate varying from 0.73 (prior to 6200 cal yr B.P.) to 1.51 mm/yr (during the late Holocene). A pollen index of water table, based on a ratio of aquatic versus non-aquatic plants has been used in order to test the hypothesis of hydrological constraints on the swampy ecosystem. Eight arid phases are evidenced by the index minima at 12 200, 11 200, 9900, 8600, 6500, 5000, 3400, 1600 cal yr B.P. The good agreement existing between this index and independent data such as (i) low-resolution East-African lake level reconstruct ions (Gillespie et al., 1983) and (ii) ?18O analyses from Arabian Sea (Sirocko et al., 1993) suggests the water table level responds to the monsoon dynamic. The Index varies periodically with a combination of 1/1515, 1/880 and 1/431 years-1 frequencies, revealed by time series analyses (Blackman-Tukey and Maximum Entropy). The extrapolation of the composite curve based on these 3 periodicities show that two major climatic events defined in the high latitudes between 1000 and 660 cal yr B.P. (Medieval Warm Period) and between 500 and 100 cal yr B.P. (Little Ice Age) are recorded in our data and show respectively high and low stands of the water table. Our results support some previous pollen-derived climate estimates in Ethiopia done by Bonnefille and Umer (1994). Moreover, the "1500 year" cycle registered in our data from the tropics, already evidenced in higher latitudes (Wijmstra et al., 1984; Bondet al., 1997; Schulz et al., 1999; Bond et al., 2001) support the hypothesis of strong teleconnections between tropical/subtropical and polar climates during the deglaciation

    Concerns regarding the safety of transfused blood have generated considerable enthusiasm for the use of technologies intended to reduce the use of allogeneic blood (blood from an unrelated donor). Platelet-rich plasmapheresis (PRP) offers an alternative approach to blood conservation. To examine the evidence for the efficacy of PRP in reducing peri-operative allogeneic red blood cell (RBC) transfusion, and the evidence for any effect on clinical outcomes such as mortality and re-operation rates. We identified studies by searching MEDLINE (1950 to 2009), EMBASE (1980 to 2009), The Cochrane Library (Issue 1, 2009), the Internet (to March 2009) and the reference lists of published articles, reports, and reviews. Controlled parallel group trials in which adult patients, scheduled for non-urgent surgery, were randomised to PRP, or to a control group which did not receive the intervention. Primary outcomes measured were: the number of patients exposed to allogeneic RBC transfusion, and the amount of RBC transfused. Other outcomes measured were: the number of patients exposed to allogeneic platelet transfusions, fresh frozen plasma, and cryoprecipitate, blood loss, re-operation for bleeding, post-operative complications (thrombosis), mortality, and length of hospital stay. Treatment effects were pooled using a random-effects model. Trial quality was assessed using criteria proposed by Schulz et al (Schulz 1995). Twenty-two trials of PRP were identified that reported data for the number of patients exposed to allogeneic RBC transfusion. These trials evaluated a total of 1589 patients. The relative risk (RR) of exposure to allogeneic blood transfusion in those patients randomised to PRP was 0.73 (95%CI 0.59 to 0.90), equating to a relative risk reduction (RRR) of 27% and a risk difference (RD) of 19% (95%CI 10% to 29%). However, significant heterogeneity of treatment effect was observed (p transfused (weighted mean difference [WMD] -0.69, 95%CI -1.93 to 0.56 units). Trials

    Free-living larval, nymphal, and adult Ixodes scapularis Say were collected from scattered locales in southern New England and New York to determine infection rates with entomopathogenic fungi. Infection rates of larvae, nymphs, males, and females were 0% (571), 0% (272), 0% (57), and 4.3% (47), respectively. Two entomopathogenic fungi were isolated from field-collected I. scapularis females from Fire Island, NY. Isolates were identified as Verticillium lecanii (Zimmermann) Viegas and Verticillium sp. (a member of the Verticillium lecanii species complex).Ixodes scapularis Say is the principal vector of Borrelia burgdorferi Johnson, Schmid, Hyde, Steigerwalt & Brenner (Burgdorfer et al. 1982, Johnson et al. 1984), the etiologic agent of Lyme disease in the northeastern and upper-midwestern United States. Control of I. scapularis is based on chemical treatment (Mather et al. 1987b; Schulze et al. 1987, 1991), environmental management (Wilson et al. 1988, Schulze et al. 1995), and habitat modification (Wilson 1986). These methods have shown variable success, and some potentially have negative environmental effects (Wilson and Deblinger 1993, Ginsberg 1994).Studies concerning natural predators, parasitoids, and pathogens of I. scapularis are rare. The use of ground-dwelling birds as tick predators has had only limited success (Duffy et al. 1992). Nymphal I. scapularis are often infected with the parasitic wasp Ixodiphagus hookeri (Howard) (Mather et al. 1987a, Hu et al. 1993, Stafford et al. 1996, Hu and Hyland 1997), but this wasp does not effectively control I. scapularis populations (Stafford et al. 1996). The entomopathogenic nematodes Steinernema carpocapsae (Weiser) and S. glaseri (Steiner) are pathogenic only to engorged female I. scapularis, and thus have limited applicability (Zhioua et al. 1995). In contrast, the entomogenous fungus Metarhizium anisopliae (Metschnikoff) Sorokin is highly pathogenic to all stages of I. scapularis, unfed as well as engorged

    Bifunctional Fischer-Tropsch (FT) catalysts that couple uniform-sized Co nanoparticles for CO hydrogenation and mesoporous zeolites for hydrocracking/isomerization reactions were found to be promising for the direct production of gasoline-range (C5-11 ) hydrocarbons from syngas. The Brønsted acidity results in hydrocracking/isomerization of the heavier hydrocarbons formed on Co nanoparticles, while the mesoporosity contributes to suppressing the formation of lighter (C1-4 ) hydrocarbons. The selectivity for C5-11 hydrocarbons could reach about 70 % with a ratio of isoparaffins to n-paraffins of approximately 2.3 over this catalyst, and the former is markedly higher than the maximum value (ca. 45 %) expected from the Anderson-Schulz-Flory distribution. By using n-hexadecane as a model compound, it was clarified that both the acidity and mesoporosity play key roles in controlling the hydrocracking reactions and thus contribute to the improved product selectivity in FT synthesis. © 2015 WILEY-VCH Verlag GmbH & Co.

Requiring a unique blend of skill, finesse, power and teamwork, ice hockey can become a lifelong recreational activity. Despite the rising popularity of the sport, there is ongoing concern about the high frequency of musculoskeletal injury associated with participation in ice hockey. Injury rates in ice hockey are among the highest in all competitive sports. Numerous research studies have been implemented to better understand the risks of injury. As a result, rule changes were adopted by the USA Hockey and Hockey Canada to raise the minimum age at which body checking is permitted to 13–14 years (Bantam level from 11–12 years (Pee Wee. Continuing the education of coaches, parents and players on rules of safe play, and emphasizing the standards for proper equipment use are other strategies being implemented to make the game safer to play. The objective of this article was to review the evaluation, management and prevention of common lower extremity youth hockey injuries.

    In this study, a WO/sub 3/-supported catalyst was prepared to conduct hydrogenation of CO for examining the product distribution and composition of hydrocarbons, using a gamma-alumina-supported catalyst for comparison. These catalysts were used under pressure to conduct a distributive reaction and the desorbing behavior of CO or H/sub 2/ at elevated temperature was measured to examine the influence of the type of carrier or the method of preparation on the activity and the distribution of products formed. The WO/sub 3/-supported catalyst gave a carbon chain length distribution that did not comply with the rule of Schulz-Flory, giving a composition richer in the isomers. Carbon number distribution is affected by Ru-dispersion, and the selectivity of isomers depends on the acidity of the carrier. Formed products distribution of the WO/sub 3/-supported reaction is attributable to the secondary reaction, which relates to the acidic point of the carrier, of the primary product formed on the metal.

    Full Text Available The manner of designing biogas plants is eagerly described by each and every seller or supplier of the respective technology. Numerous feasibility studies comprising forecasts of future operation featuring different quality levels have been written. However, it is rarely possible to obtain information comparing the anticipated future numbers and real values. Nevertheless, an evaluation of past operation of BGP is of utmost importance for calibration of the calculation methods used for designing of future BGPs. Information obtained on the basis of an evaluation is also useful for the purpose of verification of correct functionality of the equipment as well as optimisation of its operation with the objective of achieving the planned (or even better values of profitability of each respective project. A comprehensive analysis of a biogas plant is a project sensitive to accuracy of inputs. Measurements of amounts and quality of the feed substrate throughout the whole year, which comprises numerous criteria, is highly demanding and complicated, and therefore the objective of this evaluation is to analyze the performance, production and consumption of the biogas plant in the course of a calendar year (Schulz et al., 2004. Power measuring tasks are performed using calibrated gauges (which are mostly used for invoicing purposes, thus ensuring accuracy and credibility of the input data.

    Odonto-onycho-dermal dysplasia (OODD) is a rare form of ectodermal dysplasia characterized by severe oligodontia, onychodysplasia, palmoplantar hyperkeratosis, dry skin, hypotrichosis, and hyperhidrosis of the palms and soles. The ectodermal dysplasias resulting from biallelic mutations in the WNT10A gene result in highly variable phenotypes, ranging from isolated tooth agenesis to OODD and Schöpf-Schulz-Passarge syndrome (SSPS). We identified a female patient, with consanguineous parents, who was clinically diagnosed with OODD. Genetic testing showed that she was homozygous for a previously reported pathogenic mutation in the WNT10A gene, c.321C > A, p.Cys107*. The skin and nail abnormalities were for many years interpreted as psoriasis and treated accordingly. A thorough clinical examination revealed hypotrichosis and hyperhidrosis of the soles and dental examination revealed agenesis of permanent teeth except the two maxillary central incisors. Skin biopsies from the hyperkeratotic palms and soles showed the characteristic changes of eccrine syringofibroadenomatosis, which has been described in patients with ectodermal dysplasias. Together with a family history of tooth anomalies, this lead to the clinical suspicion of a hereditary ectodermal dysplasia. This case illustrates the challenges of diagnosing ectodermal dysplasia like OODD and highlights the relevance of interdisciplinary cooperation in the diagnosis of rare conditions.

    Full Text Available The purpose of this study was to empirically test two major theoretical models: a modified version of the social capital model (Pattie, Seyd and Whiteley, 2003, and the Informed Social Engagement Model (Barr and Selman, 2014; Selman and Kwok, 2010, to explain civic participation and civic knowledge of adolescents from Chile, Colombia and Mexico, using data from the International Civic and Citizenship Education Study 2009 (Schulz, et al., 2010. The models were used to identify factors associated with different levels of knowledge and civic participation: expected participation in legal and illegal protests, and electoral participation. Data were analyzed using regression analysis. Results show that the Informed Social Engagement approach (ISEM, explains better the observed differences in civic knowledge and civic participation, than the Social Capital Model (SCM. That is, the expected values associated with the variables included in the ISEM are closer to the observed values, than those predicted by the SCM. This is true for the three outcomes (expected participation in legal protests, illegal protests, and electoral participation and in the three countries analyzed (Chile, Colombia and Mexico.

  2. Parliamentarian sovereignty and technical development

    The title indicates the points of main emphasis of the contributions, and points to the programme embodied in the volume. The question is - given the tremendous and ever increasing amount of secondary problems associated with a heated technology development - whether the 'sovereign' state is at all capable of controlling, piloting and fostering technic-scientific processes. The first part ('sovereignty and parliamentarian legislator state') concentrates on the history of notions and ideas in the concept of the sovereign, modern state, and on the constitutional law in force (Dreier, Frohn); the current efficiency of parliament as an organ of control in the process of legislation is investigated (Schulze-Fielitz). The central concern of part 2 ('environmental law and technical development') are topical questions of environmental law (Hofmann, Luebbe-Wolff). Besides the analysis of dogmatic problems of a special administrative law, the major issue is whether and in how far - given modern large-scale technologies - law can adequately govern technique (Schmidt). By analyzing the relationship between technical development and possibilities for guidance by a parliamentarian constitutional state, the articles deal with a central point of intersection between state and administrative law.

    The catalytic activities of supported ruthenium for synthesis-gas conversion to hydrocarbons was found to be in the following order: TiOS > Nb2O3 > ZrO2 > SiO2 > Ta2O5 > Al2O3 > V2O5 > MoO3 > WO3 > MnO2 > ZnO. Turnover frequencies of the supported ruthenium increased with decrease in dispersion of the metal particles for every carrier material. Even the activities per unit weight of metals were higher for low-dispersion ruthenium of Al2O3, TiO2, and ZrO2. The chain-growth probability of a hydrocarbon product, which is characterized by the Schulz-Flory distribution, increased markedly with decrease in the metal dispersion irrespective of the carrier material. The catalytic activity of ruthenium particles with a dispersed ruthenium increased almost linearly with an increase in reaction pressure (up to at least 2.0 MPa). 23 references, 10 figures, 3 tables.

    Full Text Available Practitioners claim that successful leaders should be able to think out-of-the-box and “first break all the rules”. However, when it comes to organizational regulation inside some public institutions, more often than not the leaders replace the organizational creativity with an extreme exploitation of the existing rules. The “tendency to overinvest in exploitation” (Levinthal & March 1993 of the routines that proved successful in the past is well-known in the literature on organizational learning. In the present study, we examine a specific context in which a traditional rule meant to offer legitimacy to the public leaders was over-exploited up to the point when all national media reacted against the actions of the public institution. Thus, instead of obtaining more legitimacy, the leaders learned the hard way that the organizational rules should be assessed periodically and the obsolete ones be replaced/balanced with new rules, resulting from the exploratory dimension of organizational learning. We consider that an explanation for this specific case of leadership myopia may be found in a recently defined leadership style, ie, the spiritual leadership (Fry, 2003, situated in a case of over-exploiting an impermanent institutionalized rule (Schulz, 2003.

    Full Text Available The 2014 European Parliament (EP elections were characterised by a novel element in European Union (EU politics. For the first time, the major European party families put forward top candidates for President of the European Commission, the so-called Spitzenkandidaten. This paper tests whether this innovation had the potential to—at least partially—alleviate the alleged accountability deficit. We rely on original survey data to assess citizens’ preferences for each of the main Spitzenkandidaten: Jean-Claude Juncker, Martin Schulz, and Guy Verhofstadt. Our research is guided by three questions: what explains whether citizens formulate a preference for a certain Spitzenkandidat? Which factors are responsible for variations in such preferences? And, are these explanations moderated by citizens’ political awareness? We show that three factors enable citizens to formulate a preference for the Spitzenkandidaten: news exposure, general EU political information, and campaign-specific information about the Spitzenkandidaten. Furthermore, we demonstrate that only the most knowledgeable citizens are able to use party cues in their evaluations of the Spitzenkandidaten. The implications of our findings are discussed with reference to the EU’s democratic deficit debate.

    This report summarizes the recently completed Phase I of the Project for Fracture Analysis of Large-Scale International Reference Experiments (Project FALSIRE). Project FALSIRE was created by the Fracture Assessment Group (FAG) of Principal Working Group No. 3 (PWG/3) of the Organization for Economic Cooperation and Development (OECD)/Nuclear Energy Agency's (NEA's) Committee on the Safety of Nuclear Installations (CSNI). Motivation for the project was derived from recognition by the CSNI-PWG/3 that inconsistencies were being revealed in predictive capabilities of a variety of fracture assessment methods, especially in ductile fracture applications. As a consequence, the CSNI/FAG was formed to evaluate fracture prediction capabilities currently used in safety assessments of nuclear components. Members are from laboratories and research organizations in Western Europe, Japan, and the United States of America (USA). On behalf of the CSNI/FAG, the US Nuclear Regulatory Commission's (NRC's) Heavy-Section Steel Technology (HSST) Program at the Oak Ridge National Laboratory (ORNL) and the Gesellschaft fuer Anlagen--und Reaktorsicherheit (GRS), Koeln, Federal Republic of Germany (FRG) had responsibility for organization arrangements related to Project FALSIRE.

When we approached Capri by crossing the Neapolitan bay the first thing our eyes saw was the chapel of San Michele resting high above the blue waters at the top of the steep cliffs - on the edge of the abyss. This place is also the location of the Egyptian Sphinx, half lion, half woman...... that the spirit of the place adjoins a metaphysical core of architecture; and as the very core of architecture could be connected to an absolute truth so it seems that genius loci is related to truth; even though it is a truth that is not directly visible. We ask in this paper if it is a truth that is perennially...... are going to hear the Sphinx ask us questions, all these riddling puzzles, we first have to ask the Sphinx to know how to ask questions. That genius loci are present in architectural theory owes much to the Scandinavian theoretician and architect Christian Norberg-Schulz, who emphasized considerations...

  8. Superresolution upgrade for confocal spinning disk systems using image scanning microscopy (Conference Presentation)

    Confocal Spinning Disk Systems are widely used for 3D cell imaging because they offer the advantage of optical sectioning at high framerates and are easy to use. However, as in confocal microscopy, the imaging resolution is diffraction limited, which can be theoretically improved by a factor of 2 using the principle of Image Scanning Microscopy (ISM) [1]. ISM with a Confocal Spinning Disk setup (CSDISM) has been shown to improve contrast as well as lateral resolution (FWHM) from 201 +/- 20 nm to 130 +/- 10 nm at 488 nm excitation. A minimum total acquisition time of one second per ISM image makes this method highly suitable for 3D live cell imaging [2]. Here, we present a multicolor implementation of CSDISM for the popular Micro-Manager Open Source Microscopy platform. Since changes in the optical path are not necessary, this will allow any researcher to easily upgrade their standard Confocal Spinning Disk system at remarkable low cost ( 5000 USD) with an ISM superresolution option.

    2006-07-05

    This work presents an experimental study of fragmentation of helium by electron impact, in which absolute fully differential cross sections for single ionization, ionization-excitation and double ionization were determined. By applying a charged-particle imaging technique, the so-called 'reaction microscope', a large fraction of the final-state momentum space is covered, and the major limitations of previous experimental methods applied in this field could be overcome. Decisive modifications of the previous reaction microscope were undertaken, the most important one being the arrangement of the projectile beam parallel to the imaging-fields. For single ionization on helium an enhanced electron emission outside the projectile scattering plane is observed at both considered impact energies (102 eV and 1 keV), which is similar to the result found for ion-impact (M. Schulz et al., Nature (London) 422, 48 (2003)). The angle resolved cross sections obtained for double ionization at 105 eV impact energy reveal, that the process is dominated by the mutual repulsion of the three final-state continuum electrons. However, signatures of more complex dynamics are also observed. The data provide an ultimate benchmark for recently developed theories treating the dynamical three- and four-body Coulomb problem.

    Background Telecommunication is limited or even impossible for more than one-thirds of all cochlear implant (CI) users. Objective We sought therefore to study the impact of voice quality on speech perception with voice over Internet protocol (VoIP) under real and adverse network conditions. Methods Telephone speech perception was assessed in 19 CI users (15-69 years, average 42 years), using the German HSM (Hochmair-Schulz-Moser) sentence test comparing Skype and conventional telephone (public switched telephone networks, PSTN) transmission using a personal computer (PC) and a digital enhanced cordless telecommunications (DECT) telephone dual device. Five different Internet transmission quality modes and four accessories (PC speakers, headphones, 3.5 mm jack audio cable, and induction loop) were compared. As a secondary outcome, the subjective perceived voice quality was assessed using the mean opinion score (MOS). Results Speech telephone perception was significantly better (median 91.6%, P 15%) were not superior to conventional telephony. In addition, there were no significant differences between the tested accessories (P>.05) using a PC. Coupling a Skype DECT phone device with an audio cable to the CI, however, resulted in higher speech perception (median 65%) and subjective MOS scores (3.2) than using PSTN (median 7.5%, P<.001). Conclusions Skype calls significantly improve speech perception for CI users compared with conventional telephony under real network conditions. Listening accessories do not further improve listening experience. Current Skype DECT telephone devices do not fully offer technical advantages in voice quality. PMID:28438727

    Note from the AJOT Editor-in-Chief: Since 2010, the American Journal of Occupational Therapy (AJOT) has adopted reporting standards based on the Consolidated Standards of Reporting Trials (CONSORT) Statement and American Psychological Association (APA) guidelines in an effort to publish transparent clinical research that can be easily evaluated for methodological and analytical rigor (APA Publications and Communications Board Working Group on Journal Article Reporting Standards, 2008; Moher, Schulz, & Altman, 2001). AJOT has now joined 28 other major rehabilitation and disability journals in a collaborative initiative to enhance clinical research reporting standards through adoption of the EQUATOR Network reporting guidelines, described below. Authors will now be required to use these guidelines in the preparation of manuscripts that will be submitted to AJOT. Reviewers will also use these guidelines to evaluate the quality and rigor of all AJOT submissions. By adopting these standards we hope to further enhance the quality and clinical applicability of articles to our readers. Copyright © 2014 by the American Occupational Therapy Association, Inc.

    Ixodes ricinus (Linnaeus 1758) and Ixodes persulcatus (Schulze 1930) ticks are involved in the transmission of a wide variety of pathogens with considerable impact on human and animal health. The co-distribution zone of these two tick species is situated in the Baltic countries, which provides a special setting for the population studies. In the present study, genetic variability of I. ricinus ticks collected in allopatric and sympatric locations in the Baltic countries has been investigated using a sequence analysis of the mitochondrial DNA control region, 16S rRNA and cytb genes. There were 32 haplotypes (Hd: 0.8551) and 27 haplotypes (Hd:0.8213) of control region sequences from ticks in allopatric and sympatric zones detected, respectively. Out of 47 16S rRNA gene haplotypes, 32 haplotypes (Hd: 0.7213) were found in the allopatric zone and 27 (Hd:0.9572) in the sympatric zone. The Cytb gene was very conserved and monomorphic in ticks from the allopatric zone, whereas three unique haplotypes were observed in the sympatric zone. The higher number of unique haplotypes of the control region was detected in the allopatric zone. Median joining network and Fst analysis did not reveal a clear separation between ticks from the two zones. © 2016 The Society for Vector Ecology.

    Orange (Citrus sinensis) and grapefruit (Citrus paradise) peels were used as a source of pectin, which was extracted under different conditions. The peels are used under two states: fresh and residual (after essential oil extraction). Organic acid (citric acid) and mineral acid (sulfuric acid) were used in the pectin extraction. The aim of this study is the evaluation the effect of extraction conditions on pectin yield, degree of esterification “DE” and on molecular weight “Mw”. Results showed that the pectin yield was higher using the residual peels. Moreover, both peels allow the obtainment of a high methoxyl pectin with DE >50%. The molecular weight was calculated using Mark-Houwink-Sakurada equation which describes its relationship with intrinsic viscosity. This later was determined using four equations; Huggins equation, kramer, Schulz-Blaschke and Martin equation. The molecular weight varied from 1.538 x1005 to 2.47x1005 g/mol for grapefruit pectin and from 1.639 x1005 to 2.471 x1005 g/mol for orange pectin. PMID:27644093

    The problem of the unnatural transfer of exotic ticks (Acari: Ixodida) on reptiles (Reptilia) imported to Poland is presented. In the period from 2003 to 2007, 382 specimens of reptiles belonging to the following genera were investigated: Testudo, Iguana, Varanus, Gongylophis, Python, Spalerosophis, Psammophis. The reptiles most infested with ticks are imported to Poland from Ghana in Africa, and are the commonly bred terrarium reptiles: Varanus exanthematicus and Python regius. As a result of the investigations, the transfer of exotic ticks on reptiles to Poland was confirmed. There were 2104 specimens of the genera Amblyomma and Hyalomma. The following species were found: Amblyomma exornatum Koch, 1844, Amblyomma flavomaculatum (Lucas, 1846), Amblyomma latum Koch, 1844, Amblyomma nuttalli Donitz, 1909, Amblyomma quadricavum (Schulze, 1941), Amblyomma transversale (Lucas, 1844), Amblyomma varanense (Supino, 1897), Amblyomma sp. Koch, 1844, Hyalomma aegyptium (Linnaeus, 1758). All the species of ticks of genus Amblyomma revealed have been discovered in Poland for the first time. During the research, 13 cases of anomalies of morphological structure were confirmed in the ticks A. flavomaculatum, A. latum and H. aegyptium. The expanding phenomenon of the import of exotic reptiles in Poland and Central Europe is important for parasitological and epidemiological considerations, and therefore requires monitoring and wide-ranging prophylactic activities to prevent the inflow of exotic parasites to Poland.

    Like all sponges (phylum Porifera), the glass sponges (Hexactinellida) are provided with an elaborate and distinct body plan, which relies on a filigree skeleton. It is constructed by an array of morphologically determined elements, the spicules. Schulze described the largest siliceous hexactinellid sponge on Earth, the up to 3 m high Monorhaphis chuni, collected during the German Deep Sea Expedition "Valdivia" (1898-1899). This species develops an equally large bio-silica structure, the giant basal spicule (3 m × 10 mm). Using these spicules as a model, one can obtain the basic knowledge on the morphology, formation, and development of silica skeletal elements. The silica matrix is composed of almost pure silica, endowing it with unusual optophysical properties, which are superior to those of man-made waveguides. Experiments suggest that the spicules function in vivo as a nonocular photoreception system. The spicules are also provided with exceptional mechanical properties. Like demosponges, the hexactinellids synthesize their silica enzymatically via the enzyme silicatein (27 kDa protein). This enzyme is located in/embedded in the silica layers. This knowledge will surely contribute to a further utilization and exploration of silica in biomaterial/biomedical science.

    Full Text Available Ficus platyphylla gum exudates (FP gum have been analyzed for their physicochemical parameters and found to be ionic, mildly acidic, odourless, and yellowish brown in colour. The gum is soluble in water, sparingly soluble in ethanol, and insoluble in acetone and chloroform. The nitrogen (0.39% and protein (2.44% contents of the gum are relatively low. The concentrations of the cations were found to increase according to the following trend, Mn>Fe>Zn>Pb>Cu>Mg>Cd>Ca. Analysis of the FTIR spectrum of the gum revealed vibrations similar to those found in polysaccharides while the scanning electron micrograph indicated that the gum has irregular molecular shapes, arranged randomly. The intrinsic viscosity of FP gum estimated by extrapolating to zero concentrations in Huggins, Kraemer, Schulz-Blaschke, and Martin plots has an average value of 7 dL/g. From the plots of viscosity versus shear rate/speed of rotation and also that of shear stress versus shear rate, FP gum can be classified as a non-Newtonian gum with characteristics-plastic properties. Development of the Master_s curve for FP gum also indicated that the gum prefers to remain in a dilute domain (C

    Self-schemas have received increased attention as favorable targets for therapeutic intervention because of their central role in self-perception and behavior. The purpose of this integrative review was to identify, evaluate, and synthesize existing research pertaining to drinking-related self-schemas. Russell's integrative review strategy guided the search. Sixteen published works were identified, meeting criteria for evaluation ( n = 12 data-based publications and n = 4 models). The retrieved data-based publications rated fair-good using Polit and Beck's criteria; the overall body of literature rated "B" using Grimes and Schulz criteria. Retrieved models rated 4 to 7 using Fitzpatrick and Whall's criteria. The existing literature strongly supports the availability of a drinking-related self-schema among moderate-to-heavy drinking samples, and suggests a positive relationship between elaboration and drinking behavior. The relationship between valenced content of the schema and drinking behavior remains unexplored. Identifying variation in the structural properties of drinking-related self-schemas could lay the foundation for future interventions.

    Full Text Available OBJECTIVE: To analyze speech reading through Internet video calls by profoundly hearing-impaired individuals and cochlear implant (CI users. METHODS: Speech reading skills of 14 deaf adults and 21 CI users were assessed using the Hochmair Schulz Moser (HSM sentence test. We presented video simulations using different video resolutions (1280 × 720, 640 × 480, 320 × 240, 160 × 120 px, frame rates (30, 20, 10, 7, 5 frames per second (fps, speech velocities (three different speakers, webcameras (Logitech Pro9000, C600 and C500 and image/sound delays (0-500 ms. All video simulations were presented with and without sound and in two screen sizes. Additionally, scores for live Skype™ video connection and live face-to-face communication were assessed. RESULTS: Higher frame rate (>7 fps, higher camera resolution (>640 × 480 px and shorter picture/sound delay (<100 ms were associated with increased speech perception scores. Scores were strongly dependent on the speaker but were not influenced by physical properties of the camera optics or the full screen mode. There is a significant median gain of +8.5%pts (p = 0.009 in speech perception for all 21 CI-users if visual cues are additionally shown. CI users with poor open set speech perception scores (n = 11 showed the greatest benefit under combined audio-visual presentation (median speech perception +11.8%pts, p = 0.032. CONCLUSION: Webcameras have the potential to improve telecommunication of hearing-impaired individuals.

    The purpose of this study was to examine two aspects of context for peer aggression: national individualism and distributions of socioeconomic status in the school. School administrators for each school reported on their perceptions of the frequency of bullying and violence in their school. The sample comprised 990 school principals/headmasters from nationally representative samples of schools in 15 countries surveyed as part of the larger IEA Civic Education Study (Torney-Purta, Lehmann, Oswald, & Schulz, 2001). A national context of individualism was associated with violence but not bullying. Schools with high socioeconomic diversity had more bullying than homogeneously low or high socioeconomic status schools. In addition, diverse schools had more violence than affluent schools. Results suggest that bullying and violence should be investigated as separate constructs. Furthermore, contexts, such as national culture and school socioeconomic diversity, are important in understanding the prevalence of bullying and violence in schools internationally.

    Mauk, Barry; Fox, Nicola

    To address the question of what factors dictate similarities and differences between radiation belts, we present comparisons between the electron radiation belt spectra of all five strongly magnetized planets within the solar system: Earth, Jupiter, Saturn, Uranus, and Neptune. We choose the highest intensity observed electron spectrum within each system (highest specifically near 1 MeV) and compare them against expectations based on the so-called Kennel-Petschek limit (KP; 1966) for each system. For evaluating the KP limit, we begin with the new relativis-tically correct formulation of Summers et al. (2009) but then add several refinements of our own. Specifically, we: 1) utilized a much more flexible analytic spectral shape that allows us to accurately fit observed radiation belt spectra; 2) adopt the point of view that the anisotropy parameter is not a free parameter but must take on a minimal value, as originally proposed by Kennel and Petschek (1966); and 3) examine the differential characteristics of the KP limit along the lines of what Schulz and Davidson (1988) performed for the non-relativistic formula-tion. We find that three factors limit the highest electron radiation belt intensities within solar system planetary magnetospheres: a) whistler mode interactions that limit spectral intensities to a differential Kennel-Petschek limit (3 planets); b) the absence of robust acceleration pro-cesses associated with injection dynamics (1 planet); and c) material interactions between the radiation particles and clouds of gas and dust (1 planet).

    The cognitive processing of concepts, that is, abstract general ideas, has been mostly studied with language. However, other domains, such as music, can also convey concepts. Koelsch et al. [Koelsch, S., Kasper, E., Sammler, D., Schulze, K., Gunter, T., & Friederici, A. D. Music, language and meaning: Brain signatures of semantic processing. Nature Neuroscience, 7, 302-307, 2004] showed that 10 sec of music can influence the semantic processing of words. However, the length of the musical excerpts did not allow the authors to study the effect of words on musical targets. In this study, we decided to replicate Koelsch et al. findings using 1-sec musical excerpts (Experiment 1). This allowed us to study the reverse influence, namely, of a linguistic context on conceptual processing of musical excerpts (Experiment 2). In both experiments, we recorded behavioral and electrophysiological responses while participants were presented 50 related and 50 unrelated pairs (context/target). Experiments 1 and 2 showed a larger N400 component of the event-related brain potentials to targets following a conceptually unrelated compared to a related context. The presence of an N400 effect with musical targets suggests that music may convey concepts. The relevance of these results for the comprehension of music as a structured set of conceptual units and for the domain specificity of the mechanisms underlying N400 effects are discussed.

    Full Text Available This paper reports the findings of a large study on the relationship between school and civic engagement and the self-perceived participation in political activities of ethnic Chinese and South Asian immigrant students in Hong Kong. Data was col¬lected from a sample of 5,574 6th – 11th graders aged 12−19. The nature of school engagement was assessed by a self-rated questionnaire against the affective, behavioral and cognitive domains. Students’ civic engagement was measured by the ICCS student questionnaire (Schulz et al., 2009. Before running the regression analyses, Confirmatory Factor Analysis (CFA was performed and the results showed that both instruments had good construct validity and internal consistency. Consistent with the primary aim of this study, MANOVA analyses indicate significant student group differences in school engagement, and civic related self-belief and behaviours. Our findings showed that non-Chinese speaking South Asian students (NCS scored higher than their mainstream Chinese and newly arrived students from Mainland China (NAS counterparts across the dimensions of both instruments. Results of hierarchical regressions confirmed that school engagement was significant in pre¬dicting expected political participation in the future. The effects of school and civic engagement on future political participation varied significantly between all studied groups.

    Full Text Available This research developed a comprehensive computer model for a lab-scale Slurry Bubble Column Reactor (SBCR (0.1 m Dt and 2.5 m height for Fischer–Tropsch (FT synthesis under flexible operation of synthesis gas load flow rates. The variable loads of synthesis gas are set at 3.5, 5, 7.5 m3/h based on laboratory adjustments at three different operating temperatures (483, 493 and 503 K. A set of Partial Differential Equations (PDEs in the form of mass transfer and chemical reaction are successfully coupled to predict the behavior of all the FT components in two phases (gas and liquid over the reactor bed. In the gas phase, a single-bubble-class-diameter (SBCD is adopted and the reduction of superficial gas velocity through the reactor length is incorporated into the model by the overall mass balance. Anderson Schulz Flory distribution is employed for reaction kinetics. The modeling results are in good agreement with experimental data. The results of dynamic modeling show that the steady state condition is attained within 10 min from start-up. Furthermore, they show that step-wise syngas flow rate does not have a detrimental influence on FT product selectivity and the dynamic modeling of the slurry reactor responds quite well to the load change conditions.

  6. Calculation of skid resistance from texture measurements

    Full Text Available There is a wide range of routine skid resistance measurement devices on the market. All of them are measuring the friction force between a rubber wheel and the wetted road surface. Common to all of them is that they are relatively complex and costly because generally a truck carrying a large water tank is needed to wet the surface with a defined water layer. Because of the limited amount of water they can carry they are limited in range. Besides that the measurement is depending on factors like water film thickness, temperature, measurement speed, rubber aging, rubber wear and even road evenness and curviness. All of these factors will affect the skid resistance and are difficult to control. We present a concept of contactless skid resistance measurement which is based on optical texture measurement and consists of two components: measurement of the pavement texture by means of an optical measuring system and calculation of the skid resistance based on the measured texture by means of a rubber friction model. The basic assumptions underlying the theoretical approach and the model itself based on the theory of Persson are presented. The concept is applied to a laboratory device called Wehner/Schulze (W/S machine to prove the theoretical approach. The results are very promising. A strong indication could be provided that skid resistance could be measured without contact in the future.

  7. Transcultural Writers and Transcultural Literature in the Age of Global Modernity

    Full Text Available Peer reviewed article. In our rapidly globalising world, cultures, as well as societies and identities, tend to be more fluid, less irreducibly different and less 'territorially fixed' than in the past (Schulze-Engler 2007, p. 27. Especially now, when cosmopolitan issues and pluralistic sensibilities - driven by transnational and transcommunal experiences - tend to become more relevant. It is within this emerging social context that a new generation of mobile writers, on the move across cultural and national boundaries, has started expressing a "transcultural" sensibility and mode of being, fostered by "the process of self-distancing, self-estrangement, and self criticism of one's own cultural identities and assumptions" (Epstein 1999, p. 307. In this paper, I argue that the main element that distinguishes these early 'transcultural writers' from their precursors and/or 'cousin species' (migrant/exile/diasporic/postcolonial writers - albeit all belonging to the wider 'genus' of 'the literature of mobility' - is their relaxed, neonomadic attitude when facing issues linked to identity, nationality, rootlessness and dislocation. An attitude that reflects itself also in their creative outputs, which can already be inscribed within the realm of transcultural literature, a literature able to transcend the borders of a single culture in its choice of topic, vision and scope, thus contributing to promote a wider global literary perspective (Pettersson 2006.

    To evaluate the effect of technological advances in the past 20 years on the hearing performance of a large cohort of adult cochlear implant (CI) patients. Individual, retrospective, cohort study. According to technological developments in electrode design and speech-processing strategies, we defined five virtual intervals on the time scale between 1984 and 2008. A cohort of 1,005 postlingually deafened adults was selected for this study, and their hearing performance with a CI was evaluated retrospectively according to these five technological intervals. The test battery was composed of four standard German speech tests: Freiburger monosyllabic test, speech tracking test, Hochmair-Schulz-Moser (HSM) sentence test in quiet, and HSM sentence test in 10 dB noise. The direct comparison of the speech perception in postlingually deafened adults, who were implanted during different technological periods, reveals an obvious improvement in the speech perception in patients who benefited from the recent electrode designs and speech-processing strategies. The major influence of technological advances on CI performance seems to be on speech perception in noise. Better speech perception in noisy surroundings is strong proof for demonstrating the success rate of new electrode designs and speech-processing strategies. Standard (internationally comparable) speech tests in noise should become an obligatory part of the postoperative test battery for adult CI patients.

    El trabajo de Rossemberg et al (1999), estudia las edades relativas de cúmulos globulares galácticos mediante el análisis de ciertos parámetros morfológicos de los diagramas color-magnitud de dichos cúmulos. Este trabajo se centra en tres puntos: analizar la consistencia de los resultados obtenidos por Rossemberg et al (1999) al emplear observaciones en el sistema fotométrico de Washington, más precisamente, las magnitudes C y T1 en lugar de las magnitudes V e I utilizadas por dichos autores. De la existencia de colores integrados, metalicidad y edad (relativa) para 21 de los cúmulos utilizados en dicho trabajo, se analiza la consistencia de estos resultados con las dependencias de color integrado como función de la edad y la metalicidad que se desprenden de los modelos teóricos de luz integrada por Worthey (1994), Schulz (2002) y Lee et al (2002). Por último se lleva a cabo una breve comparación de la morfología de los diagramas color-magnitud de los cúmulos globulares y de las isocronas utilizadas, a fin de intentar identificar algunas de las posibles causas de las diferencias observadas en los incisos anteriores.

    This report summarizes the recently completed Phase I of the Project for Fracture Analysis of Large-Scale International Reference Experiments (Project FALSIRE). Project FALSIRE was created by the Fracture Assessment Group (FAG) of Principal Working Group No. 3 (PWG/3) of the Organization for Economic Cooperation and Development (OECD)/Nuclear Energy Agency`s (NEA`s) Committee on the Safety of Nuclear Installations (CSNI). Motivation for the project was derived from recognition by the CSNI-PWG/3 that inconsistencies were being revealed in predictive capabilities of a variety of fracture assessment methods, especially in ductile fracture applications. As a consequence, the CSNI/FAG was formed to evaluate fracture prediction capabilities currently used in safety assessments of nuclear components. Members are from laboratories and research organizations in Western Europe, Japan, and the United States of America (USA).

  13. Chandra Discovers the X-ray Signature of a Powerful Wind from a Galactic Microquasar

    2000-11-01

    NASA's Chandra X-ray Observatory has detected, for the first time in X rays, a stellar fingerprint known as a P Cygni profile--the distinctive spectral signature of a powerful wind produced by an object in space. The discovery reveals a 4.5-million-mile-per-hour wind coming from a highly compact pair of stars in our galaxy, report researchers from Penn State and the Massachusetts Institute of Technology in a paper they will present on 8 November 2000 during a meeting of the High-Energy Astrophysics Division of the American Astronomical Society in Honolulu, Hawaii. The paper also has been accepted for publication in The Astrophysical Journal Letters. "To our knowledge, these are the first P Cygni profiles reported in X rays," say researchers Niel Brandt, assistant professor of astronomy and astrophysics at Penn State, and Norbert S. Schulz, research scientist at the Massachusetts Institute of Technology. The team made the discovery during their first observation of a binary-star system with the Chandra X-ray Observatory, which was launched into space in July 1999. The system, known as Circinus X-1, is located about 20,000 light years from Earth in the constellation Circinus near the Southern Cross. It contains a super-dense neutron star in orbit around a normal fusion-burning star like our Sun. Although Circinus X-1 was discovered in 1971, many properties of this system remain mysterious because Circinus X-1 lies in the galactic plane where obscuring dust and gas have blocked its effective study in many wavelengths. The P Cygni spectral profile, previously detected primarily at ultraviolet and optical wavelengths but never before in X rays, is the textbook tool astronomers rely on for probing stellar winds. The profile looks like the outline of a roller coaster, with one really big hill and valley in the middle, on a data plot with velocity on one axis and the flow rate of photons per second on the other. It is named after the famous star P Cygni, in which such

The evaluation and construction of such water balances is implemented with the presented package. During the (manual) calibration of a model or in the scope of model development, many model runs and iterations are necessary. Thus, users are often interested in comparing different model results in a visual way in order to learn about the model and to analyse parameter-changes on the output. A method to illuminate these differences and the evolution of changes is also included. References: • Gupta, H.V.; Wagener, T.; Liu, Y.

In this study, our method is applied to the case of fossil fuel CO2 emissions from the European region. Taking into account that the uncertainty in available bottom-up estimates of the total CO2 emissions from that region is believed to be rather small, the case considered enables validation of our method, understanding its advantages and limitations, as well as examination of feasibility of its application to the world's regions with potentially much larger uncertainties in CO2 emissions.

    2016-04-01

    Interdisciplinary scientific and societal knowledge plays an increasingly important role in global change research. Also, in the field of water resources interdisciplinarity as well as cooperation with stakeholders from outside academia have been recognized as important. In this contribution, we revisit an integrated regional modelling system (DANUBIA), which was developed by an interdisciplinary team of researchers and relied on stakeholder participation in the framework of the GLOWA-Danube project from 2001 to 2011 (Mauser and Prasch 2016). As the model was developed before the current increase in literature on participatory modelling and interdisciplinarity, we ask how a socio-hydrology approach would have helped and in what way it would have made the work different. The present contribution firstly presents the interdisciplinary concept of DANUBIA, mainly with focus on the integration of human behaviour in a spatially explicit, process-based numerical modelling system (Roland Barthel, Janisch, Schwarz, Trifkovic, Nickel, Schulz, and Mauser 2008; R. Barthel, Nickel, Meleg, Trifkovic, and Braun 2005). Secondly, we compare the approaches to interdisciplinarity in GLOWA-Danube with concepts and ideas presented by socio-hydrology. Thirdly, we frame DANUBIA and a review of key literature on socio-hydrology in the context of a survey among hydrologists (N = 184). This discussion is used to highlight gaps and opportunities of the socio-hydrology approach. We show that the interdisciplinary aspect of the project and the participatory process of stakeholder integration in DANUBIA were not entirely successful. However, important insights were gained and important lessons were learnt. Against the background of these experiences we feel that in its current state, socio-hydrology is still lacking a plan for knowledge integration. Moreover, we consider necessary that socio-hydrology takes into account the lessons learnt from these earlier examples of knowledge integration

    Uranium rods prepared by sintering-extrusion in the {alpha} or {beta} phase (at various extrusion ratios) using slightly oxidised powders have been subjected to the thermal cycling test. At the same time, dilatometric and X-ray techniques have made it possible to determine the structures produced in these materials during their fabrication. A relationship is then proposed linking the texture to the increase in length on thermal cycling. 1. Two types of rods have been studied: Sintered-extruded in the {beta} phase: low density (88 per cent theoretical density), large grain-size and no preferential texture. Sintered-extruded in the {alpha} phase: high density (96 per cent theoretical density), fine grain with pronounced preferential texture. 2. After 1000 thermal cycles between 20 and 550 C, the increases in length are the following: 2 per cent for a uranium sintered-extruded in the {beta} phase (with surface cracking). between 14 and 56 per cent according to the extrusion ratio for on uranium sintered-extruded in the {alpha} phase (with no surface effects). 3. In the case of rods sintered-extruded in the {alpha} phase, determination of the pole figure using the Schulz reflection method showed the existence of two preferential orientations parallel to the direction of extrusion: one close to [100], the other close to [110]. By dilatometry it was then possible to measure quantitatively the proportion of each constituent in the overall texture and to show that an increase in the percentage of [100] occurs with increasing amounts of cold-working. 4. Finally, by comparing 2 and 3 it can be seen that the increases in length due to thermal cycling are connected to the percentage amounts of each component. It seems that the increases in length diminish as the percentage of [100] increases. On the other hand the behaviour of materials containing large amount of [110] is still far from clear.

    The textures produced in zirconium by the extrusion at 730 deg C of a cylindrical billet in the form of a plate having a rectangular cross-section, have been studied by the Schulz method using an isotropic standard. These textures have been determined both parallel to the plane of the plate and parallel to the plane of the sides, All the results are analyzed in a final discussion which makes it possible to show, in particular near the edges of the plate, that certain components of the textures observed in the two series of recordings are in fact aspects of the same texture seen from two different angles, It is shown furthermore that the zirconium thus shaped has cold-work textures and als recrystallisation textures formed after the preceding cold-working, If the observed textures are considered schematically, it can be see that two of these have already been described in the literature and are similar to those found in rolled products: these textures are such that the (0001) planes are inclined at 36 deg C and 60 deg C respectively with respect to a plan tangential to the curve (envelope of transverse flow rates) resulting from the extrusion geometry under consideration; the third texture is defined. by the fact that the (0001) plane is orthogonal to the exterior surfaces of the plate. The direction of extrusion associated with these planes and common to the three textures is of the type <1010>, Dilatometric tests have been carried out on samples taken both parallel and perpendicular to the extrusion direction, These tests show that the zirconium is dilatometrically anisotropic and that a plot of ({alpha}{sub v})-a against temperature shows a change of gradient at 400 deg C, this latter effect may be due to the change in the electronic configuration of the metal occurring at this temperature.

  3. Job Crafting: Older Workers’ Mechanism for Maintaining Person-Job Fit

    Aging at work is a dynamic process. As individuals age, their motives, abilities and values change as suggested by life-span development theories (Lang and Carstensen, 2002; Kanfer and Ackerman, 2004). Their growth and extrinsic motives weaken while intrinsic motives increase (Kooij et al., 2011), which may result in workers investing their resources in different areas accordingly. However, there is significant individual variability in aging trajectories (Hedge et al., 2006). In addition, the changing nature of work, the evolving job demands, as well as the available opportunities at work may no longer be suitable for older workers, increasing the likelihood of person-job misfit. The potential misfit may, in turn, impact how older workers perceive themselves on the job, which leads to conflicting work identities. With the traditional job redesign approach being a top-down process, it is often difficult for organizations to take individual needs and skills into consideration and tailor jobs for every employee (Berg et al., 2010). Therefore, job crafting, being an individualized process initiated by employees themselves, can be a particularly valuable mechanism for older workers to realign and enhance their demands-abilities and needs-supplies fit. Through job crafting, employees can exert personal agency and make changes to the task, social and cognitive aspects of their jobs with the goal of improving their work experience (Wrzesniewski and Dutton, 2001). Building on the Life Span Theory of Control (Heckhausen and Schulz, 1995), we posit that job crafting, particularly cognitive crafting, will be of increasing value as employees age. Through reframing how they think of their job and choosing to emphasize job features that are personally meaningful, older workers can optimize their resources to proactively redesign their jobs and maintain congruent, positive work identities.

    Since blood cortisol (F) and melatonin (MLT) display a circadian secretion pattern and since the saliva concentration of this hormones is an excellent indicator of its blood levels the measurement of salivary F and MLT may be used for examining circadian rhythmicity. In this study the relationship between salivary F and MLT was explored. For this purpose it was necessary first to establish and validate a radioimmunoassay for F in saliva: salivary F was determined by a direct radioimmunoassay using cortisol-3-(O-carboxymethyl) oximino-(2-( 125 I)iodohistamin) as tracer and cortisol-3-CMO-BSA antiserum. The parallel measurement of F levels in saliva and serum of adults gave an excellent correlation (r=0.87, p 0.00956x ). Serum F was assayed on the Abott TDX-System using a radioimmunofluorescence method. Secondly, using this assay the circadian saliva F pattern was determined as well as the pattern of salivary MLT in 9 young, healthy volunteers. For saliva MLT estimations a previously published method was applied (Schulz et al 1990). Using a computerized program (RHYTHM) written by Eve v. Cauter (1979), the hormone data of each individuum were examined for circadian rhythmicity and its acrophase (time of occurrence of the maximum of a sinusoid fitted to the data). The F acrophase occurred between 7:00 and 12:00 h (mean: 3:33 h, SD: 104.4 min). The easy stress-free non invasive nature of saliva collection makes saliva to one of the most accessible body fluids and of high value in studying the circadian system in healthy humans as well as in infants, children, pregnant women and anaemic patients. Measurements of salivary F and MLT may help to elucidate not only the circadian rhythms of these hormones under normal and pathological conditions but it may also provide insight in physiology and pathology of the circadian system in general.

  6. Motive of Madenss in Schulz’s Short Stories. A Psychological-Literary Study

    Full Text Available Representation of various modes, forms, symptoms and degrees of mental illnesses, frequent in The Street of Crocodiles, are analysed in two perspectives: psychological and literary-cultural. Using the tools of modern psychology, the article interprets the pathological symptoms of Touya, Maria, aunt Agatha, and various other characters, most importantly the advancing illness of father Joseph, who displays symptoms of schizophrenia. Schulz uses a language filled with metaphors, blurring the border between symptoms of illness and metaphors, between the imaginary and the real, and between health and illness, norm and pathology, between the human and the animal. Schulz’s representation of madness opposes the modern understanding, which is dominated by analytical, rationalist identification of an illness, related to a socially determined norm of mental health. It brings back the premodern quality to madness, which becomes a divine phenomenon, related to the pagan rite of fertility, to the “orgy of life” and Dionysian element, and to Freudian life drive. Dionysius and Freud meet in an area independent from the rules of culture and reason: the return to nature, including the nature in a human being. Here, madness becomes a “basic figure” and “the ultimate ur-schema”, as they belong to the unintellectual, basic, ecstatic sphere. This is related to the imperative of penetration of areas that threaten the “balance of the soul”, to address the topic that shows “the scar of removal”, and forces us to ask the question of limits of humanity.

J Strength Cond Res XX(X): 000-000, 2018-Mouthguards (MGs) improve sports safety. However, airway obstruction and a resulting decrease in performance are theoretical disadvantages regarding their use. The study aim was to assess possible limitations of a "vented" MG on aerobic performance in handball. The physiological effects were investigated in 14 male professional players in a newly developed handball-specific course. The measured values were oxygen uptake, ventilation, heart rate, and lactate. Similar oxygen uptake (V[Combining Dot Above]O2) values were observed with and without MG use (51.9 ± 6.4 L·min·kg vs. 52.1 ± 10.9 L·min·kg). During maximum load, ventilation was markedly lower with the vented MG (153.1 ± 25 L·min vs. 166.3 ± 20.8 L·min). The endexpiratory concentrations of O2 (17.2 ± 0.5% vs. 17.6 ± 0.8%) and CO2 (4.0 ± 0.5% vs. 3.7 ± 0.6%) were significantly lower and higher, respectively, when using the MG. The inspiration and expiration times with and without the MG were 0.6 ± 0.1 seconds vs. 0.6 ± 0.1 seconds and 0.7 ± 0.2 seconds vs. 0.6 ± 0.2 seconds (all not significant), respectively, indicating that there was no relevant airflow restriction. The maximum load was not significantly affected by the MG. The lower ventilation for given V[Combining Dot Above]O2 values associated with MG use may be an effect of improved biomechanics and lower respiratory drive of the peripheral musculature.

  8. The role of otolith size in hearing – Insights from cichlid fishes

    Full Text Available Otolithic end organs in fishes function as accelerometers and are involved in the senses of balance and hearing (e.g. Popper et al. 2005. Otolith mass and shape are likely decisive factors influencing otolith motion, but while it is largely unknown how different shapes affect otolith movement relative to the sensory epithelium (Popper et al. 2005, greater otolith mass is predicted to result in enhanced stimulation of sensory hair cells and improved hearing (Lychakov and Rebane 2005. What few studies exist on this topic, however, yielded contradicting results in that they did or did not find a correlation between increased otolith mass and enhanced hearing (see Kéver et al. 2014. We investigated the relationship between otolith morphology (including 3D-models of otoliths based on high-resolution microCT imaging and otolith weight and hearing abilities in cichlids while comparing three species (Etroplus maculatus, Hemichromis guttatus, Steatocranus tinanti with different swimbladder morphology and hearing abilities (Schulz-Mirbach et al. 2014. We predicted Etroplus maculatus—the species that displays the best hearing sensitivities—to possess larger/heavier otoliths. As swimbladder extensions in this species are connected to the lagena, we further predicted to find heavier lagenar otoliths. Compared to H. guttatus and S. tinanti, E. maculatus showed the heaviest saccular otoliths, while lagenar otoliths were significantly thinner and lighter than in the former two species, apparently contradicting the hypothesis that the lagena and its otolith are primarily involved in improved hearing abilities. Our results support the idea that there is no ‘simple’ relationship between otolith weight, ancilliary auditory structures and hearing abilities. 3D-models of inner ears and otoliths may be ideally suited for future studies modeling complex otolith motion and thus, may provide a better understanding of how otolith morphology contributes to inner

    A number of studies have demonstrated wide disparities in health among racial/ethnic groups and by gender, yet few have examined how race/ethnicity and gender intersect or combine to affect the health of older adults. The tendency of prior research to treat race/ethnicity and gender separately has potentially obscured important differences in how health is produced and maintained, undermining efforts to eliminate health disparities. The current study extends previous research by taking an intersectionality approach (Mullings & Schulz, 2006), grounded in life course theory, conceptualizing and modeling trajectories of functional limitations as dynamic life course processes that are jointly and simultaneously defined by race/ethnicity and gender. Data from the nationally representative 1994-2006 US Health and Retirement Study and growth curve models are utilized to examine racial/ethnic/gender differences in intra-individual change in functional limitations among White, Black and Mexican American Men and Women, and the extent to which differences in life course capital account for group disparities in initial health status and rates of change with age. Results support an intersectionality approach, with all demographic groups exhibiting worse functional limitation trajectories than White Men. Whereas White Men had the lowest disability levels at baseline, White Women and racial/ethnic minority Men had intermediate disability levels and Black and Hispanic Women had the highest disability levels. These health disparities remained stable with age-except among Black Women who experience a trajectory of accelerated disablement. Dissimilar early life social origins, adult socioeconomic status, marital status, and health behaviors explain the racial/ethnic disparities in functional limitations among Men but only partially explain the disparities among Women. Net of controls for life course capital, Women of all racial/ethnic groups have higher levels of functional

    Full Text Available Background: Hyalomma anatolicum is the well-known hard tick, which is one of the most important livestock and hu­man pathogens vector, wide range in host and distributed in all over the Hyalomma geographic fauna as well as in Iran. Taxonomy of the Hyalomma ssp. is debatable whereas their identification is a problematic work. The reasons for this claim is time consuming Delpy’s researches in Iran also Schulze School, Feldman-Muhsam and the Russian tick workers. We would like to understand morphometric variation in the field collected H. anatolicum in Iran also validat­ing some morphologic quantitative and qualitative characters.Methods: A total 247 field-collected tick specimens from different geographical regions in west of Iran includes Khuzestan and Lorestan Provinces were studied. The morphologic characters of the ticks were measured by the cali­brated stereomicroscope ‎armed scaled lens. The measurements were analyzed using SPSS ‎for windows, version 16 on an IBM PC, ‎so varied shapes of species in different geographic ‎regions were drawn by the ‎aid of a drawing tube con­nected to a light stereomicroscope.‎Results: One way ANOVA test revealed significant differences among the quantitative parameters in five zones (P<‎‎ 0.‎‎00‎‎1‎ also each zone to other zone by Post Hoc Tests e.g. LSD. No significant differences in the lateral grooves length/conscutum length ratio parameter were found.Conclusion: Morphometric variation in Hyalomma spp is poorly studied. The variation in range and quantity of the mor­phometric parameters of H.anatolicum ‎underlies that the correct recognition and key construction for Hyalomma spe­cies dependes ‎on a complement morphometric study on the other species.

To better understand this variability in results, an exploratory physiological study was performed comparing the effects of helium/oxygen mixture (78%/22% to that of medical air.Methods: The gas mixtures were administered to healthy, asthmatic, and chronic obstructive pulmonary disease (COPD participants, both moderate and severe (6 participants in each disease group, a total of 30; at rest and during submaximal cycling exercise with equivalent work rates. Measurements of ventilatory parameters, forced spirometry, and ergospirometry were obtained.Results: There was no statistical difference in ventilatory and cardiac responses to breathing helium/oxygen during submaximal exercise. For asthmatics, but not for the COPD participants, there was a statistically significant benefit in reduced metabolic cost, determined through measurement of oxygen uptake, for the same exercise work rate. However, the individual data show that there were a mixture of responders and nonresponders to helium/oxygen in all of the groups.Conclusion: The inconsistent response to helium/oxygen between individuals is perhaps the key drawback to the more effective and widespread use of helium/oxygen to increase exercise capacity and for other therapeutic applications.

    The crystal structure and Raman spectra of quartz are calculated by using first-principles method in a pressure range from 0 to 5 GPa. The results show that the lattice constants (a, c, and V) decrease with increasing pressure and the a-axis is more compressible than the c axis. The Si–O bond distance decreases with increasing pressure, which is in contrast to experimental results reported by Hazen et al. [Hazen R M, Finger L W, Hemley R J and Mao H K 1989 Solid State Communications 725 507–511], and Glinnemann et al. [Glinnemann J, King H E Jr, Schulz H, Hahn T, La Placa S J and Dacol F 1992 Z. Kristallogr. 198 177–212]. The most striking changes are of inter-tetrahedral O–O distances and Si–O–Si angles. The volume of the tetrahedron decreased by 0.9% (from 0 to 5 GPa), which suggests that it is relatively rigid. Vibrational models of the quartz modes are identified by visualizing the associated atomic motions. Raman vibrations are mainly controlled by the deformation of the tetrahedron and the changes in the Si–O–Si bonds. Vibrational directions and intensities of atoms in all Raman modes just show little deviations when pressure increases from 0 to 5 GPa. The pressure derivatives (dν i /dP) of the 12 Raman frequencies are obtained at 0 GPa–5 GPa. The calculated results show that first-principles methods can well describe the high-pressure structural properties and Raman spectra of quartz. The combination of first-principles simulations of the Raman frequencies of minerals and Raman spectroscopy experiments is a useful tool for exploring the stress conditions within the Earth. (paper)

    There is mixed evidence on the effectiveness of vaccination-related interventions. A major limitation of most intervention studies is that they do not apply randomized controlled trials (RCTs), the method that, over the last 2 decades, has increasingly been considered as the only method to provide proof of the effectiveness of an intervention and, consequently, as the most important instrument in deciding whether to adopt an intervention or not. This study, however, holds that methods other than RCTs also can produce meaningful results. The aim of this study was to evaluate 2 mobile phone-based interventions aimed at increasing parents' knowledge of the measles-mumps-rubella (MMR) vaccination (through elements of gamification) and their psychological empowerment (through the use of narratives), respectively. The 2 interventions were part of an RCT. We conducted 2 studies with the RCT participants: a Web-based survey aimed at assessing their rating of the tool regarding a number of qualities such as usability and usefulness (N=140), and qualitative telephonic interviews to explore participants' experiences with the app (N=60). The results of the survey showed that participants receiving the knowledge intervention (alone or together with the empowerment intervention) liked the app significantly better compared with the group that only received the empowerment intervention (F 2,137 =15.335; Pbenefits of the vaccination at the same time.

    Highlights: • Role of operating experience in loss-of-coolant-accident (LOCA) frequency assessment. • Plant-to-plant variability in calculated LOCA frequency. • Frequency of double-ended-guillotine-break (DEGB). • Uncertainties in LOCA frequencies. • Risk management insights. - Abstract: As a tribute to the published work by S.H. Bush, S. Beliczey and H. Schulz, this paper assesses the progress with methods and techniques for quantifying the reliability of piping systems in commercial nuclear power plants on the basis of failure rate estimates derived from field experience data in combination with insights and results from probabilistic fracture mechanics analyses and expert elicitation exercises. This status assessment is made from a technical perspective obtained through development of location-specific loss-of-coolant-accident (LOCA) frequencies for input to risk-informed resolution of the generic safety issue (GSI) 191. The methods and techniques on which these GSI-191 applications are based build on a body of work developed by the authors during a period spanning more than two decades. The insights that are presented and discussed in this paper cover today’s knowledge base concerning how to utilize a risk-informed approach to the assessment of piping reliability in the context of probabilistic risk assessment (PRA) in general and the resolution of GSI-191 in particular. Specifically the paper addresses the extent to which LOCA frequencies vary from location to location within a reactor coolant system pressure boundary (RCPB) for a given plant as well as vary from plant to plant, and the reasons for these variabilities. Furthermore, the paper provides the authors’ perspectives on interpretations and applications of information extracted from an expert elicitation process to obtain LOCA frequencies as documented in NUREG-1829 and how to apply this information to GSI-191. Finally, this paper documents technical insights relative to mitigation of

    The Younger Toba Tuff eruption, approximately 73 ka ago, is the largest known for the Quaternary and its climate, environmental and human consequences are keenly debated (Oppenheimer, 2011).While the distribution (Rose and Chesner, 1987; Rose and Chesner, 1990; Chesner et al., 1991; Schulz et al., 2002; Von Rad et al., 2002) , geochemical properties (Shane et al., 1995; Westgate et al., 1998) and volcanic significance (Rampino and Self, 1982; Rampino and Self, 1993; Rampino and Ambrose, 2000; Oppenheimer, 2002; Mason et al., 2004)of the YTT have been widely studied, few attention has been given to the significance of the distal volcanic ash deposits within their receiving basin context. Although several studies exist on the impact of pyroclastic flows on proximal rivers and lakes (Collins and Dunne, 1986; Thompson et al., 1986; Hayes et al., 2002; Németh and Cronin, 2007), only few address the issues of the dynamic of preservation of super-distal fine ash deposits in rivers (also due to the lack of direct data on super-eruptions). It has also been demonstrated that models of the styles and timing of distal volcanoclastic re-sedimentation are more complicated than those developed for proximal settings of stratovolcanoes (Kataoka et al., 2009). We present an analysis of the taphonomy (intended as accumulation and preservation) of distal volcanic ash in fluvial and lacustrian contexts in newly discovered Toungest Toba Tuff sites in the Lenggong valley, western Peninsular Malaysia. The paper aims to characterise the nature of distal tephras in fluvial environments towards a stratigraphic distinction between primary ash and secondary ash, characterisation of the pre-ash fall receiving environment in term of fluvial dynamic and landscape morphology, and assessment of the time of recovery.

  19. On adiabatic pair potentials of highly charged colloid particles

    Generalizing the Debye-Hückel formalism, we develop a new mean field theory for adiabatic pair potentials of highly charged particles in colloid dispersions. The unoccupied volume and the osmotic pressure are the key concepts to describe the chemical and thermodynamical equilibrium of the gas of small ions in the outside region of all of the colloid particles. To define the proper thermodynamic quantities, it is postulated to take an ensemble averaging with respect to the particle configurations in the integrals for their densities consisting of the electric potential satisfying a set of equations that are derived by linearizing the Poisson-Boltzmann equation. With the Fourier integral representation of the electric potential, we calculate first the internal electric energy of the system from which the Helmholtz free energy is obtained through the Legendre transformation. Then, the Gibbs free energy is calculated using both ways of the Legendre transformation with respect to the unoccupied volume and the summation of chemical potentials. The thermodynamic functions provide three types of pair potentials, all of which are inversely proportional to the fraction of the unoccupied volume. At the limit when the fraction factor reduces to unity, the Helmholtz pair potential turns exactly into the well known Derjaguin-Landau-Verwey-Overbeek repulsive potential. The Gibbs pair potential possessing a medium-range strong repulsive part and a long-range weak attractive tail can explain the Schulze-Hardy rule for coagulation in combination with the van der Waals-London potential and describes a rich variety of phenomena of phase transitions observed in the dilute dispersions of highly charged particles.

First-line antibiotic therapy for treating melioidosis is usually the synthetic β-lactam, ceftazidime (CAZ, as almost all B. pseudomallei strains are susceptible to this drug. However, acquired CAZ resistance can develop in vivo during treatment with CAZ, which can lead to mortality if therapy is not switched to a different drug in a timely manner. Serial B. pseudomallei isolates obtained from an acute Thai melioidosis patient infected by a CAZ susceptible strain, who ultimately succumbed to infection despite being on CAZ therapy for the duration of their infection, were analyzed. Isolates that developed CAZ resistance due to a proline to serine change at position 167 in the β-lactamase PenA were identified. Importantly, these CAZ resistant isolates remained sensitive to the alternative melioidosis treatments; namely, amoxicillin-clavulanate, imipenem, and meropenem. Lastly, real-time polymerase chain reaction-based assays capable of rapidly identifying CAZ resistance in B. pseudomallei isolates at the position 167 mutation site were developed. The ability to rapidly identify the emergence of CAZ resistant B. pseudomallei populations in melioidosis patients will allow timely alterations in treatment strategies

    This paper presents the comparison of skid resistance of wearing course made of SMA (Stone Mastic Asphalt) mixtures which differ in resistance to polishing of coarse aggregate. Dolomite, limestone, granite and trachybasalt were taken for investigation. SMA mixtures have the same nominal size of aggregate (11 mm) and very similar aggregate particle-size distribution in mineral mixtures. Tested SMA11 mixtures were designed according to EN 13108-5 and Polish National Specification WT-2: 2014. Evaluation of the skid resistance has been performed using the FAP (Friction After Polishing) test equipment also known as the Wehner/Schulze machine. Laboratory method enables to compare the skid resistance of different types of mixtures under specified conditions simulating polishing processes. Tests were performed on both the specimens made of each coarse aggregate and SMA11 mixtures containing these aggregates. Measuring of friction coefficient μm was conducted before and during polishing process up to 180 0000 passes of polishing head. Comparison of the results showed differences in sensitivity to polishing among particular mixtures which depend on the petrographic properties of rock used to produce aggregate. Limestone and dolomite tend to have a fairly uniform texture with low hardness which makes these rock types susceptible to rapid polishing. This caused lower coefficient of friction for SMA11 mixtures with limestone and dolomite in comparison with other test mixtures. These significant differences were already registered at the beginning of the polishing process. Limestone aggregate had lower value of μm before starting the process than trachybasalt and granite aggregate after its completion. Despite the differences in structure and mineralogical composition between the granite and trachybasalt, slightly different values of the friction coefficient at the end of polishing were obtained. Images of the surface were taken with the optical microscope for better

    Full Text Available El esparcimiento y la recreación frecuentemente se definen de manera individual y, por lo tanto, no se entienden o interpretan universalmente. Los diferentes contextos culturales pueden originar distintas definiciones o significados de esparcimiento. El reto de las personas que estudian el esparcimiento es interpretarlo de tal forma que ayude a las personas a entender acerca de su valor en la calidad de vida. Por consiguiente, este estudio examinó el significado de esparcimiento para estudiantes de un curso de estudios generales de la Universidad de Costa Rica (UCR y de Montclair State University (MSU, una universidad estatal del noreste de Estados Unidos, en el I ciclo lectivo del 2009. Las personas participantes fueron 388 estudiantes (149 hombres y 240 mujeres, promedio edad = 21 años, DE = 3.3 del curso de Actividad Deportiva, de carreras de grado de ambas universidades. El estudiantado contestó el Inventario de Significados de Esparcimiento (Schulz y Watkins, 2007. Este cuestionario incluye cuatro categorías: pasar el tiempo, escapar de presiones, tomar decisiones y lograr autorrealización. En términos generales, las diferencias estadísticamente significativas entre los grupos universitarios se relacionaron con el concepto de esparcimiento como "pasar el tiempo" y "tomar decisiones". Las percepciones de esparcimiento como "escapar de presiones" y "lograr autorrealización" sólo fueron el resultado de diferencias estadísticas significativas de casos específicos. Los resultados indican que los estudiantes de MSU tienden más a percibir esparcimiento como "pasar el tiempo" y "tomar decisiones" que la contraparte costarricense.

    The textures produced in zirconium by the extrusion at 730 deg C of a cylindrical billet in the form of a plate having a rectangular cross-section, have been studied by the Schulz method using an isotropic standard. These textures have been determined both parallel to the plane of the plate and parallel to the plane of the sides, All the results are analyzed in a final discussion which makes it possible to show, in particular near the edges of the plate, that certain components of the textures observed in the two series of recordings are in fact aspects of the same texture seen from two different angles, It is shown furthermore that the zirconium thus shaped has cold-work textures and als recrystallisation textures formed after the preceding cold-working, If the observed textures are considered schematically, it can be see that two of these have already been described in the literature and are similar to those found in rolled products: these textures are such that the (0001) planes are inclined at 36 deg C and 60 deg C respectively with respect to a plan tangential to the curve (envelope of transverse flow rates) resulting from the extrusion geometry under consideration; the third texture is defined. by the fact that the (0001) plane is orthogonal to the exterior surfaces of the plate. The direction of extrusion associated with these planes and common to the three textures is of the type , Dilatometric tests have been carried out on samples taken both parallel and perpendicular to the extrusion direction, These tests show that the zirconium is dilatometrically anisotropic and that a plot of (α v )-a against temperature shows a change of gradient at 400 deg C, this latter effect may be due to the change in the electronic configuration of the metal occurring at this temperature.

    Objective To analyze speech reading through Internet video calls by profoundly hearing-impaired individuals and cochlear implant (CI) users. Methods Speech reading skills of 14 deaf adults and 21 CI users were assessed using the Hochmair Schulz Moser (HSM) sentence test. We presented video simulations using different video resolutions (1280×720, 640×480, 320×240, 160×120 px), frame rates (30, 20, 10, 7, 5 frames per second (fps)), speech velocities (three different speakers), webcameras (Logitech Pro9000, C600 and C500) and image/sound delays (0–500 ms). All video simulations were presented with and without sound and in two screen sizes. Additionally, scores for live Skype™ video connection and live face-to-face communication were assessed. Results Higher frame rate (>7 fps), higher camera resolution (>640×480 px) and shorter picture/sound delay (<100 ms) were associated with increased speech perception scores. Scores were strongly dependent on the speaker but were not influenced by physical properties of the camera optics or the full screen mode. There is a significant median gain of +8.5%pts (p = 0.009) in speech perception for all 21 CI-users if visual cues are additionally shown. CI users with poor open set speech perception scores (n = 11) showed the greatest benefit under combined audio-visual presentation (median speech perception +11.8%pts, p = 0.032). Conclusion Webcameras have the potential to improve telecommunication of hearing-impaired individuals. PMID:23359119

    Quality of life and needforsocial support in persons diagnosed with multiple sclerosis (MS) are to a large extent determined by the degree of their disability. The aim of the study was to analyze an association between specific forms of MS, subjectively perceived quality of life and social support. The study included subjects with established diagnosis of MS, treated at rehabilitation centers, hospitals and in a home setting, as well as the members of patient organizations. After being informed about objectives of the study, type of included tasks and way to complete them, each participant was handed out a set of questionnaires: Berlin Social Support Scales (Łuszczyńska, Kowalska, Schwarzer, Schulz), Quality of Life Questionnaire (WHOQOLBREF), as well as a survey developed specifically for the purposes of this project. The results were subjected to statistical analysis with STATA 12 package. The study included a total of 110 persons (67 women and 43 men). Quality of life overall, as well in physical, psychological, social relationships and environmental health domains, turned out to be particularly important in patients with primary-progressive MS. Irrespective of MS type, social support overall did not play a significant role on univariate analysis. However, subgroup analysis according to sex demonstrated that men with MS received social support four times less often than women. Quality of life in individuals with primary-progressive MS is significantly lower than in patients presenting with other types of this disease. Men with MS are more likely to present with worse scores for social support overall. They are less likely both to acknowledge the need for support and to realize the availability of support they actually need.

We have previously shown that mice lacking Mmp2 share similar syndromic features with the human disorder, and at the cellular level, Mmp2-/- mouse osteoblasts and osteoclasts have reduced numbers and proliferation rates at critical developmental time points. While previously hypothesized, the effect of MMP2 loss on apoptosis has not been examined in this system. We therefore sought to clarify its role in mediating the developmental defects in Mmp2-/- mice using immunohistochemistry, immunoblot analysis, and quantitative reverse transcription polymerase chain reaction analysis. We also explored the effects of MMP2 inhibition in the osteogenic sarcoma cell line SaOS2. Loss of MMP2 resulted in increased apoptosis and caspase activation both in vitro and in vivo. MMP2-deficient cells had increased Fas expression and reduced levels of the key survival signals p-FAK, p-ERK, cFLIP, and Bcl-2. Notably, and in marked contrast to their original characterization, there was a significant increase in the in utero demise of homozygous Mmp2-/- embryos. Specifically, litters from heterozygous crosses consistently yielded nearly 85% fewer than expected homozygous Mmp2-/- pups. Taken together, our findings highlight a new role for MMP2 in preventing apoptosis during development and growth. Keywords

    Full Text Available Andreas Schulze-Bonhage, Mandy Hintz Epilepsy Center, University Medical Center Freiburg, Freiburg, Germany Abstract: Perampanel (PER is a novel antiepileptic drug recently introduced for the adjunctive treatment in epilepsy patients aged 12 years or older with partial-onset seizures with or without secondary generalization in the US and Europe. Its antiepileptic action is based on noncompetitive inhibition of postsynaptic AMPA receptors, decreasing excitatory synaptic transmission. Evaluation of efficacy in three placebo-controlled randomized Phase III studies showed that add-on therapy of PER decreased seizure frequencies significantly compared to placebo at daily doses between 4 mg/day and 12 mg/day. PER’s long half-life of 105 hours allows for once-daily dosing that is favorable for patient compliance with intake. Long-term extension studies showed a 62.5%–69.6% adherence of patients after 1 year of treatment, comparing favorably with other second-generation antiepileptic drugs. Whereas these trials demonstrated an overall favorable tolerability profile of PER, nonspecific central nervous system adverse effects like somnolence, dizziness, headache, and fatigue may occur. In addition, neuropsychiatric disturbances ranging from irritability to suicidality were reported in several case reports; both placebo-controlled and prospective long-term extension trials showed a low incidence of such behavioral and psychiatric complaints. For early recognition of neuropsychiatric symptoms like depression, anxiety, and aggression, slow titration and close monitoring during drug introduction are mandatory. This allows on the one hand to recognize patients particularly susceptible to adverse effects of the drug, and on the other hand to render the drug’s full potential of seizure control available for the vast majority of patient groups tolerating the drug well.

    Response of the rainbelt over Africa to dust direct radiative forcing has been an area of lively debate and is a subject of ongoing research. Previous modeling studies have contrasting results producing different amplitudes or even signs of responses. Uncertainties in the dust radiative forcing are thought to be the major cause of discrepancies in the simulated responses among various studies. The imaginary part of mineral dust shortwave refractive index, which defines the dust absorptivity, has a wide range of values estimated from various observational and modeling studies, as it depends on dust chemical composition and mineralogy. Balkanski et al. (2007) estimated dust shortwave refractive indices by assuming 3 different hematite contents, 0.9%, 1.5% and 2.7% by volume, which corresponds to inefficient, standard, and very efficient dust shortwave absorption, respectively. To investigate the sensitivity of the position and intensity of the tropical rainbelt over Africa and its extension to the Arabian Peninsula to dust shortwave absorption, we have conducted ensembles of numerical simulations for each of the three dust absorptivity scenarios using a high resolution Atmospheric General Circulation Model (AGCM), GFDL's High Resolution Atmospheric Model (HiRAM), at a spatial resolution of 25 km. We found that the strength and the latitudinal extent of the rainbelt are very sensitive to dust shortwave absorption, as well as circulations at various spatiotemporal scales that drive the climate of the region.

It has been applied the resolution method by spherical harmonical series expansion for cubic and hexagonal microscopic symmetry and orthorhombic macroscopic symmetry. For yielding the microscopic symmetries it has been necessary the implementation of algorithmic for calculation the spherical harmonic of specific surface. The generation of Legendre Polynomial, based on the experimental data in relation to a and β step angles, is execution in real time. In the introduction of data, the graphical representation of pole figure is drawn in stereo graphic projection, being possible to the analyst three dimensional (3D) visualization. An internal routine verify validity of the Miller indexes, being possible to analyst the correction. The program exhibit the possible corrections applied to experimental data: defocusing, background and orientation of lamination direction (β angle). The correction of the defocusing and background is the executed automatically based on the optic used in the X-ray equipment (Schulz geometric). It has been implemented a routine of graphic manipulation of the contour iso lines for generation of the orientation distribution function (ODF), with easy manipulation of the number of lines and colors. In the ODF graphic, with the action of the mouse cursor on any section, it is visualized the values of Euler angles (φ 1 , Φ, φ 2 ) and of the respective f(g) intensity. Concomitantly, there is 3D graphic visualization of the crystal position in relation to the rolling direction. There is the possibility of graphic visualization in 3D of any section of the ODF. It is also possible the graphic visualization of the texture fiber. This program was named Texture Analysis Program (TAP). (author)

    Specific communication training is currently not integrated into anesthesiology curricula. At the same time communication is an important key factor when working with colleagues, in the physician-patient relationship, during management of emergencies and in avoiding or reducing the legal consequences of adverse medical events. Therefore, focused attention should be brought to this area. In other high risk industries, specific communication training has been standard for a long time and in medicine there is an approach to teach and train these soft skills by simulation. Systematic communication training, however, is rarely an established component of specialist training. It is impossible not to communicate whereby nonverbal indications, such as gestures, mimic expression, posture and tone play an important part. Miscommunication, however, is common and leads to unproductive behavior. The cause of this is not always obvious. This article provides an overview of the communication models of Shannon, Watzlawick et al. and Schulz von Thun et al. and describes their limitations. The "Process Communication Model®" (PCM) is also introduced. An overview is provided with examples of how this tool can be used to look at the communication process from a systematic point of view. People have different psychological needs. Not taking care of these needs will result in individual stress behavior, which can be graded into first, second and third degrees of severity (driver behavior, mask behavior and desperation). These behavior patterns become exposed in predictable sequences. Furthermore, on the basis of this model, successful communication can be established while unproductive behavior that occurs during stress can be dealt with appropriately. Because of the importance of communication in all areas of medical care, opportunities exist to focus research on the influence of targeted communication on patient outcome, complications and management of emergencies.

    To evaluate the role of gender on the hearing performance of postlingually deafened adult patients with cochlear implants. Individual retrospective cohort study. There were 638 postlingually deafened adults (280 men and 358 women) selected for a retrospective evaluation of their hearing performance with cochlear implants. Both genders underwent the same surgical and rehabilitative procedures and benefited from the latest technological advances available. There was no significant difference in the age, duration of deafness, and preoperative hearing performance between the genders. The test battery was composed of the Freiburger Monosyllabic Test, Speech Tracking, and the Hochmair-Schulz-Moser (HSM) sentence test in quiet and in 10-dB noise. The results of 5 years of follow-up are presented here. Genders showed a similar performance in Freiburger Monosyllabic Test and Speech Tracking Test. However, in the HSM test in noise, men performed slightly better than women in all of the follow-up sessions, which was statistically significant at 2 and 4 years after implantation. Although normal-hearing women use more predictive cognitive strategies in speech comprehension and are supposed to have a more efficient declarative memory system, this may not necessarily lead to a better adaptation to the altered auditory information delivered by a cochlear implant. Our study showed that in more complex listening situations such as speech tests in noise, men tend to perform slightly better than women. Gender may have an influence on the hearing performance of postlingually deafened adults with cochlear implants.

    John Rittmeister was a German neurologist (1898-1943) who was executed in Berlin-Plötzensee because of his decision to support organized political resistance against National Socialism. He grew up in a socially and materially privileged environment and following his final school examinations (Abitur) in 1917 he volunteered for war duties despite limited physical capabilities and was posted as a private to the war front in the Italian Alps and the Champagne district. While he was there he made his first social experiences outside his original surroundings. After the war he studied medicine and following the final state examinations and graduation he progressed to specialist training as a neurologist in Munich. At this time he came into contact with C.G. Jung. During a study period in London in 1929 he worked for several weeks as a resident at Toynbee Hall, a university institution in Whitechapel and experienced the methods of community work used there which were known under the term settlement movement. He continued his specialist activities in the neurological clinic in Zürich founded by C. von Monakow. Following the experiences in London he broke up with C.G.

In 1939 he became director of the Policlinic of the German Institute for Psychological Research and Psychotherapy. Probably also due to his own war experiences in 1941/1942 he participated in the drafting of a flyer for the Schulze-Boysen/Harnack group against the war and after 8 months in prison he was executed in Berlin on 13 May 1943.

    Linear alpha-olefins, especially 1-hexene and 1-octene, are key components for the production of LLDPE and the demand for 1-hexene and 1-octene increased enormously in recent years. Here we review the new processes for 1-octene production based on homogeneous catalysts. Sasol's coal-based high temperature Fischer-Tropsch technology produces an Anderson-Schulz-Flory distribution of hydrocarbons with high alpha-olefin content and the desired alkenes, including 1-heptene and 1-octene, are separated by distillation. In this case, as in the SHOP process, 1-octene constitutes only a minor part of the total yield. Nowadays other technologies are being applied or considered for on-purpose 1-octene production: hydroformylation of 1-heptene, the telomerization of 1,3-butadiene, and ethene tetramerization. 1-Heptene can be converted in three steps to 1-octene: (1) hydroformylation of 1-heptene to octanal, (2) hydrogenation of octanal to 1-octanol, and (3) dehydration of 1-octanol to 1-octene. This process was commercialized by Sasol. Dow commercialized a process based on butadiene. Telomerization of butadiene with methanol in the presence of a palladium catalyst yields 1-methoxy-2,7-octadiene, which is fully hydrogenated to 1-methoxyoctane in the next step. Subsequent cracking of 1-methoxyoctane gives 1-octene and methanol for recycle. Recently highly active and stable phosphine based systems were reported that show particularly good performance for the industrially attractive feedstock, the C{sub 4} cut of the paraffin cracker. 1-Hexene can be obtained by ethene trimerization by a family of catalysts based mainly on Cr.

    Highlights: • Role of operating experience in loss-of-coolant-accident (LOCA) frequency assessment. • Plant-to-plant variability in calculated LOCA frequency. • Frequency of double-ended-guillotine-break (DEGB). • Uncertainties in LOCA frequencies. • Risk management insights. - Abstract: As a tribute to the published work by S.H. Bush, S. Beliczey and H. Schulz, this paper assesses the progress with methods and techniques for quantifying the reliability of piping systems in commercial nuclear power plants on the basis of failure rate estimates derived from field experience data in combination with insights and results from probabilistic fracture mechanics analyses and expert elicitation exercises. This status assessment is made from a technical perspective obtained through development of location-specific loss-of-coolant-accident (LOCA) frequencies for input to risk-informed resolution of the generic safety issue (GSI) 191. The methods and techniques on which these GSI-191 applications are based build on a body of work developed by the authors during a period spanning more than two decades. The insights that are presented and discussed in this paper cover today’s knowledge base concerning how to utilize a risk-informed approach to the assessment of piping reliability in the context of probabilistic risk assessment (PRA) in general and the resolution of GSI-191 in particular. Specifically the paper addresses the extent to which LOCA frequencies vary from location to location within a reactor coolant system pressure boundary (RCPB) for a given plant as well as vary from plant to plant, and the reasons for these variabilities. Furthermore, the paper provides the authors’ perspectives on interpretations and applications of information extracted from an expert elicitation process to obtain LOCA frequencies as documented in NUREG-1829 and how to apply this information to GSI-191. Finally, this paper documents technical insights relative to mitigation of

    Dementia is being increasingly recognised as a major public health issue for our ageing populations. A critical aspect of supporting people with dementia is facilitating their participation in meaningful activities. However, research to date has not drawn on theories of ageing from developmental psychology that would help undergird the importance of such meaningful activity. For the first time, we connect existing activity provision for people with dementia with developmental psychology theories of ageing. We reviewed the literature in two stages: first, we narratively searched the literature to demonstrate the relevance of psychological theories of ageing for provision of meaningful activities for people with dementia, and in particular focused on stage-based theories of adult development (Carl Jung and Erik Erikson), gerotranscendence (Tornstam), selective optimisation with compensation (Baltes and Baltes), and optimisation in primary and secondary control (Heckhausen and Schulz). Second, we systematically searched PubMed and PsycINFO for studies with people with dementia that made use of the aforementioned theories. The narrative review highlights that activity provision for people with dementia goes beyond mere pleasure to meeting fundamental psychological needs. More specifically, that life review therapy and life story work address the need for life review; spiritual/religious activities address the need for death preparation; intergenerational activities address the need for intergenerational relationships; re-acquaintance with previously conducted leisure activities addresses the need for a sense of control and to achieve life goals; and pursuit of new leisure activities addresses the need to be creative. The systematic searches identified two studies that demonstrated the utility of applying Erikson's theory of psychosocial development to dementia care. We argue for the importance of activity provision for people with dementia to help promote wellbeing

    The paper presents the evaluation of skid resistance of EAC (Exposed Aggregate Concrete) pavements which differ in aggregate graining compositions. The tests were carried out on concrete mixes with a maximum aggregate size of 8 mm. Three types of coarse aggregates were selected depending on their resistance to polishing which was determined on the basis of the PSV (Polished Stone Value). Basalt (PSV 48), gabbro (PSV 50) and trachybasalt (PSV 52) aggregates were chosen. For each type of aggregate three graining compositions were designed, which differed in the content of coarse aggregate > 4mm. Their content for each series was as follows: A - 38%, B - 50% and C - 68%. Evaluation of the skid resistance has been performed using the FAP (Friction After Polishing) test equipment also known as the Wehner/Schulze machine. Laboratory method enables to compare the skid resistance of different types of wearing course under specified conditions simulating polishing processes. In addition, macrotexture measurements were made on the surface of each specimen using the Elatexure laser profile. Analysis of variance showed that at significance level α = 0.05, aggregate graining compositions as well as the PSV have a significant influence on the obtained values of the friction coefficient μm of the tested EAC pavements. The highest values of the μm have been obtained for EAC with the lowest amount of coarse aggregates (compositions A). In these cases the resistance to polishing of the aggregate does not significantly affect the friction coefficients. This is related to the large areas of cement mortar between the exposed coarse grains. Based on the analysis of microscope images, it was observed that the coarse aggregates were not sufficiently exposed. It has been proved that PSV significantly affected the coefficient of friction in the case of compositions B and C. This is caused by large areas of exposed coarse aggregate. The best parameters were achieved for the EAC pavements

    Pitch Lake is located in the southwest peninsula of the island near La Brea in Trinidad and Tobago, covering an area of approximately 46 hectares. It was discovered in the year 1595 and is the largest of three natural asphalt lakes that exist on Earth. Pitch Lake is a large oval shaped reservoir composed of dominantly hydrocarbon compounds, but also includes minor amounts of clay and muddy water. It is a natural liquid asphalt desert, which is nourished by a form of petroleum consisting of mostly asphaltines from the surrounding oil-rich region. The hydrocarbons mix with mud and gases under high pressure during upward seepage, and the lighter portion evaporates or is volatilized, which produces a high-viscosity liquid asphalt residue. The residue on and near the surface is a hydrocarbon matrix, which poses extremely challenging environmental conditions to microorganisms characterized by an average low water activity in the range of 0.49 to 0.75, recalcitrant carbon substrates, and toxic chemical compounds. Nevertheless, an active microbial community of archaea and bacteria, many of them novel strains, was found to inhabit the liquid hydrocarbon matrix of Pitch Lake. Geochemical analyses of minerals, done by our team, which revealed sulfates, sulfides, silicates, and metals, normally associated with deep-water hydrothermal vents leads to our new hypothetical model to describe the origins of Pitch Lake and its importance to atmospheric and earth sciences. Pitch Lake is likely the terrestrial equivalent of an offshore submarine asphalt volcano just as La Brea Tar Pits are in some ways an on-land version of the asphalt volcanoes discovered off shore of Santa Barbara by Valentine et al. in 2010. Asphalt volcanism possibly also creates the habitat for chemosynthetic life that is widespread in this lake, as reported by Schulze-Makuch et al. in 2011 and Meckenstock et al. in 2014.

  19. Cobalt carbide nanoprisms for direct production of lower olefins from syngas

    Lower olefins—generally referring to ethylene, propylene and butylene—are basic carbon-based building blocks that are widely used in the chemical industry, and are traditionally produced through thermal or catalytic cracking of a range of hydrocarbon feedstocks, such as naphtha, gas oil, condensates and light alkanes. With the rapid depletion of the limited petroleum reserves that serve as the source of these hydrocarbons, there is an urgent need for processes that can produce lower olefins from alternative feedstocks. The ‘Fischer-Tropsch to olefins’ (FTO) process has long offered a way of producing lower olefins directly from syngas—a mixture of hydrogen and carbon monoxide that is readily derived from coal, biomass and natural gas. But the hydrocarbons obtained with the FTO process typically follow the so-called Anderson-Schulz-Flory distribution, which is characterized by a maximum C2-C4 hydrocarbon fraction of about 56.7 per cent and an undesired methane fraction of about 29.2 per cent (refs 1, 10, 11, 12). Here we show that, under mild reaction conditions, cobalt carbide quadrangular nanoprisms catalyse the FTO conversion of syngas with high selectivity for the production of lower olefins (constituting around 60.8 per cent of the carbon products), while generating little methane (about 5.0 per cent), with the ratio of desired unsaturated hydrocarbons to less valuable saturated hydrocarbons amongst the C2-C4 products being as high as 30. Detailed catalyst characterization during the initial reaction stage and theoretical calculations indicate that preferentially exposed {101} and {020} facets play a pivotal role during syngas conversion, in that they favour olefin production and inhibit methane formation, and thereby render cobalt carbide nanoprisms a promising new catalyst system for directly converting syngas into lower olefins.

  20. Sensitivity of tropical rainbelt over Africa and Middle East to dust shortwave absorption: Experiments using a high resolution AGCM

    Response of the rainbelt over Africa to dust direct radiative forcing has been an area of lively debate and is a subject of ongoing research. Previous modeling studies have contrasting results producing different amplitudes or even signs of responses. Uncertainties in the dust radiative forcing are thought to be the major cause of discrepancies in the simulated responses among various studies. The imaginary part of mineral dust shortwave refractive index, which defines the dust absorptivity, has a wide range of values estimated from various observational and modeling studies, as it depends on dust chemical composition and mineralogy. Balkanski et al. (2007) estimated dust shortwave refractive indices by assuming 3 different hematite contents, 0.9%, 1.5% and 2.7% by volume, which corresponds to inefficient, standard, and very efficient dust shortwave absorption, respectively. To investigate the sensitivity of the position and intensity of the tropical rainbelt over Africa and its extension to the Arabian Peninsula to dust shortwave absorption, we have conducted ensembles of numerical simulations for each of the three dust absorptivity scenarios using a high resolution Atmospheric General Circulation Model (AGCM), GFDL\\'s High Resolution Atmospheric Model (HiRAM), at a spatial resolution of 25 km. We found that the strength and the latitudinal extent of the rainbelt are very sensitive to dust shortwave absorption, as well as circulations at various spatiotemporal scales that drive the climate of the region.

    Since blood cortisol (F) and melatonin (MTL) display a circadian secretion pattern and since the saliva concentration of these hormones is an excellent indicator of its blood levels the measurement of salivary F and MLT may be used for examining circadian rhythmicity. In these study the relationship between salivary F and MLT was explored. For this purpose it was necessary first to establish and validate a radioimmunoassay for F in saliva: salivary F was determined by a direct radioimmunoassay using cortisol-3-(O-carboxymethyl) oximino-(2- ( 125 I)iodohistamin) as tracer and cortisol-3-CMO-BSA antiserum. The parallel measurement of F levels in saliva and serum of adults gave an excellent correlation (r=0.87, p 0.00956x ). Serum F was assayed on the Abott TDX-System using a radioimmunofluorescence method. Secondly, using this assay the circadian saliva F pattern was determined as well as the pattern of salivary MLT in 9 young, healthy volunteers. For saliva MLT estimations a previously published method was applied (SCHULZ et al 1990). Using a computerized program (RHYTHM) written by EVE v. CAUTER (1979), the hormone data of each individuum were examined for circadian rhythmicity and its acrophases (time of occurrence of the maximum of a sinusoid fitted to the data). The F acrophase occured between 7:00 and 12:00 h (Mean: 8:06 h, SD: 93.8 min). The acrophase for MLT was found between 0:00 and 6:00 h (Mean: 3:33 h, SD: 104.4 min). There was a phase difference between both hormones of 3 to 7 hours (Mean: 292.5 min, SD: 74.7 min). The easy stress-free non-invasive nature of saliva collection makes saliva to one of the most accessible body fluids and of high value in studying the circadian system in healthy humans as well as in infants, children, pregnant women and anaemic patients. Measurements of salivary F and MLT may help to elucidate not only the circadian rhythms of these hormones under normal and pathological conditions but it may also provide insight in

    Polarimetric astronomical observations on dust clouds and regolithic surfaces require laboratory simulations on samples to provide information on properties (size distribution, porosity, refractive index) of the scattering media. Similarly, in-situ radar investigations in the solar system require laboratory studies on samples to infer physical properties (e.g. porosity, ice/dust ratio) of sub-surfaces and interiors. Recent developments are illustrated with present studies related to the Rosetta mission, which begun its rendezvous with comet 67P/Churyumov-Gerasimeko (C-G) and landed the Philae module on its nucleus in 2014.We will summarize laboratory simulations with the PROGRA2 suite of instruments that study (in the visible to near IR domain) the polarimetric properties of dust samples in microgravity conditions or on surfaces [1], with emphasis on the interpretation of polarimetric observations of C-G, during its previous perihelion passages from Earth observatories, and currently from HST [2,3]. The presence of large dust particles in the pre-perihelion coma previously inferred from remote observations agrees with Rosetta ground truth [4]. We will also present measurements on the permittivity (in the millimeter to meter domain) of various dust samples, with emphasis on porous samples [5,6]. Results provide constraints on the properties of the subsurface and interior of C-G, as explored by MIRO on Rosetta and CONSERT on Philae.Such studies are relevant for the interpretation of polarimetric observations of other dust clouds (e.g. debris disks, interplanetary dust cloud, clouds in planetary atmospheres) and surfaces (e.g. planets, moons), as well as for those of other radar characterization studies (e.g. Mars, moons, asteroids).[1] Levasseur-Regourd et al.

    A model for radial diffusion caused by electromagnetic disturbances was published by Falthammar (1965) using a two-parameter model of the disturbance perturbing a background dipole magnetic field. Schulz and Lanzerotti (1974) extended this model by recognizing the two parameter perturbation as the leading (non--dipole) terms of the Mead Williams magnetic field model. They emphasized that the magnetic perturbation in such a model induces an electric ield that can be calculated from the motion of field lines on which the particles are ‘frozen’. Roederer and Zhang (2014) describe how the field lines on which the particles are frozen can be calculated by tracing the unperturbed field lines from the minimum-B location to the ionospheric footpoint, and then tracing the perturbed field (which shares the same ionospheric footpoint due to the frozen -in condition) from the ionospheric footpoint back to a perturbed minimum B location. The instantaneous change n Roederer L*, dL*/dt, can then be computed as the product (dL*/dphi)*(dphi/dt). dL*/Dphi is linearly dependent on the perturbation parameters (to first order) and is obtained by computing the drift across L*-labeled perturbed field lines, while dphi/dt is related to the bounce-averaged gradient-curvature drift velocity. The advantage of assuming a dipole background magnetic field, as in these previous studies, is that the instantaneous dL*/dt can be computed analytically (with some approximations), as can the DLL that results from integrating dL*/dt over time and computing the expected value of (dL*)^2. The approach can also be applied to complex background magnetic field models like T89 or TS04, on top of which the small perturbations are added, but an analytical solution is not possible and so a numerical solution must be implemented. In this talk, I discuss our progress in implementing a numerical solution to the calculation of DL*L* using arbitrary background field models with simple electromagnetic

    Politicians and their public relations advisors depend on the mass communication media to transmit messages dailyand communicate effectively. The development of the mass media, from traditional to new, has changed the working conditions of these professions where one inevitably affects the other. Consequently, the way of formatting information in the newshas changed, along with the way of monitoring the political developments and informs the public on political activities. Amajor role in this process, over and above the political actors, has advisers for public relations, who choose moments andevents to publicise (PR-ization). With the increasing influence of public relations to media reports, politics also changes thepicture of the media and the impact on media coverage. Similarly, the impact on the manner in which the media reportprocess, what topics will be discussed topics and what tone the given information will have. We are living in a world characterized by mediation (Mazzoleni and Schulz, 1999) of the politics and the society as a whole, because politics and publicrelations necessarily need the media to communicate with their audiences. In this regard, we can talk about PR-izationmedia as the fundamental role of public relations practitioners affect attitudes, which skillfully make careful design ofmessages and events that are not included herein are the three professions each other should one without the other does notmake sense.

    The main challenge in de novo genome assembly of DNA-seq data is certainly to deal with repeats that are longer than the reads. In de novo transcriptome assembly of RNA-seq reads, on the other hand, this problem has been underestimated so far. Even though we have fewer and shorter repeated sequences in transcriptomics, they do create ambiguities and confuse assemblers if not addressed properly. Most transcriptome assemblers of short reads are based on de Bruijn graphs (DBG) and have no clear and explicit model for repeats in RNA-seq data, relying instead on heuristics to deal with them. The results of this work are threefold. First, we introduce a formal model for representing high copy-number and low-divergence repeats in RNA-seq data and exploit its properties to infer a combinatorial characteristic of repeat-associated subgraphs. We show that the problem of identifying such subgraphs in a DBG is NP-complete. Second, we show that in the specific case of local assembly of alternative splicing (AS) events, we can implicitly avoid such subgraphs, and we present an efficient algorithm to enumerate AS events that are not included in repeats. Using simulated data, we show that this strategy is significantly more sensitive and precise than the previous version of KisSplice (Sacomoto et al. in WABI, pp 99-111, 1), Trinity (Grabherr et al. in Nat Biotechnol 29(7):644-652, 2), and Oases (Schulz et al. in Bioinformatics 28(8):1086-1092, 3), for the specific task of calling AS events. Third, we turn our focus to full-length transcriptome assembly, and we show that exploring the topology of DBGs can improve de novo transcriptome evaluation methods. Based on the observation that repeats create complicated regions in a DBG, and when assemblers try to traverse these regions, they can infer erroneous transcripts, we propose a measure to flag transcripts traversing such troublesome regions, thereby giving a confidence level for each transcript. The originality of our work when

Health care consumers in Switzerland show a high appraisal of the importance of physician-approved criteria for assessing health care performance and a moderate self-perception of how capable they are of assessing the quality and performance of a physician. This study supports that health care consumers are differentiating between aspects they perceive they would be able to evaluate after a visit to a physician (such as attributes of structure and the interpersonal skills of a doctor), and others that lay beyond their ability to make an accurate judgment about (such as technical skills of a physician and outcome of care). ©Fabia Rothenfluh, Peter J Schulz.

    Nickel (Ni) based nanoparticles and nanochains were incorporated as fillers in polydimethylsiloxane (PDMS) elastomers and then these mixtures were thermally cured in the presence of a uniform magnetic field. In this way, macroscopically structured-anisotropic PDMS-Ni based magnetorheological composites were obtained with the formation of pseudo-chains-like structures (referred as needles) oriented in the direction of the applied magnetic field when curing. Nanoparticles were synthesized at room temperature, under air ambient atmosphere (open air, atmospheric pressure) and then calcined at 400 °C (in air atmosphere also). The size distribution was obtained by fitting Small Angle X-ray Scattering (SAXS) experiments with a polydisperse hard spheres model and a Schulz-Zimm distribution, obtaining a size distribution centered at (10.0 ± 0.6) nm with polydispersivity given by σ = (8.0 ± 0.2) nm. The SAXS, X-ray powder diffraction, and Transmission Electron Microscope (TEM) experiments are consistent with single crystal nanoparticles of spherical shape (average particle diameter obtained by TEM: (12 ± 1) nm). Nickel-based nanochains (average diameter: 360 nm; average length: 3 μm, obtained by Scanning Electron Microscopy; aspect ratio = length/diameter ∼ 10) were obtained at 85 °C and ambient atmosphere (open air, atmospheric pressure). The magnetic properties of Ni-based nanoparticles and nanochains at room temperature are compared and discussed in terms of surface and size effects. Both Ni-based nanoparticles and nanochains were used as fillers for obtaining the PDMS structured magnetorheological composites, observing the presence of oriented needles. Magnetization curves, ferromagnetic resonance (FMR) spectra, and strain-stress curves of low filler's loading composites (2% w/w of fillers) were determined as functions of the relative orientation with respect to the needles. The results indicate that even at low loadings it is

In KCl (80 mM-pre-contracted-endothelium-denuded rings, EEEP elicited concentration-dependent relaxation (EC50= 128.2±11.2 µg/mL, Maximal Response 76.8±3.4%. Vasorelaxation has also been achieved with tonic contractions evoked by the L-type Ca2+ channel agonist Bay K 8644 (EC50 80.2±9.1 µg/mL, Maximal Response 86.3±8.3%. In addition, in a depolarizing medium, EEEP inhibited CaCl2 (30-500 µg/mL induced contractions and caused a concentration-dependent rightward shift of the relaxation curves. Lastly, the tropane alkaloid pungencine caused vasorelaxation in mesenteric arteries resembling to the EEEP responses. These results suggests that EEEP induces hypotension and vasorelaxation, at least in part, due to the reduction in [Ca2+]i in vascular smooth muscle cells.

There is growing support for integration of palliative care’s holistic approach to suffering, but insufficient understanding of how this would happen in the complex team context of HF care. This study examined how HF care teams, as defined by patients, work together to provide care to patients with advanced disease. Methods: Team members were identified by each participating patient, generating team sampling units (TSUs for each patient. Drawn from five study sites in three Canadian provinces, our dataset consists of 209 interviews from 50 TSUs. Drawing on a theoretical framing of HF teams as complex adaptive systems (CAS, interviews were analyzed using the constant comparative method associated with constructivist grounded theory. Results: This paper centers on the dominant theme of system practices, how HF care delivery is reported to work organizationally, socially, and practically, and describes two subthemes: “the way things work around here”, which were commonplace, routine ways of doing things, and “the way we make things work around here”, which were more conscious, effortful adaptations to usual practice in response to emergent needs. An adaptive practice, often a small alteration to routine, could have amplified effects beyond those intended by the innovating team

A monthly injection of palivizumab has been used for prophylaxis of serious RSV infections among high-risk children in 71 countries since 1998 and approval for use in the Russian Federation was obtained in February 2010. A recommendation for RSV prophylaxis in the Russian Federation would require knowledge of the prevalence and seasonality of RSV in that country.Methods: In a prospective, multicenter, epidemiological study of the prevalence, seasonality, and peak occurrence of RSV infection, children aged ≤2 years hospitalized for lower respiratory tract infections in three regions of the Russian Federation, from September 2008 through April 2009, were screened and tested for RSV using rapid immunochromatography of nasopharyngeal lavage. For subjects who were tested positive, hospitalization data were collected.Results: Of 519 children aged ≤2 years enrolled from September 11, 2008 through April 26, 2009, 197 tested positive for RSV (38.0%, 95% CI: 33.8, 42.3. The onset of the 2008–2009 RSV season in the Russian Federation occurred in late October 2008, similar to what is observed in other northern temperate zones. Peak activity occurred in early April 2009, when 62% of children enrolled tested positive for RSV.Conclusion: The prevalence

    Full Text Available Net community production (NCP and carbon to nutrient uptake ratios were studied during a large-scale mesocosm experiment on ocean acidification in Kongsfjorden, western Svalbard, during June–July 2010. Nutrient depleted fjord water with natural plankton assemblages, enclosed in nine mesocosms of ~ 50 m3 in volume, was exposed to pCO2 levels ranging initially from 185 to 1420 μatm. NCP estimations are the cumulative change in dissolved inorganic carbon concentrations after accounting for gas exchange and total alkalinity variations. Stoichiometric coupling between inorganic carbon and nutrient net uptake is shown as a ratio of NCP to a cumulative change in inorganic nutrients. Phytoplankton growth was stimulated by nutrient addition half way through the experiment and three distinct peaks in chlorophyll a concentration were observed during the experiment. Accordingly, the experiment was divided in three phases. Cumulative NCP was similar in all mesocosms over the duration of the experiment. However, in phases I and II, NCP was higher and in phase III lower at elevated pCO2. Due to relatively low inorganic nutrient concentration in phase I, C : N and C : P uptake ratios were calculated only for the period after nutrient addition (phase II and phase III. For the total post-nutrient period (phase II + phase III ratios were close to Redfield, however they were lower in phase II and higher in phase III. Variability of NCP, C : N and C : P uptake ratios in different phases reflects the effect of increasing CO2 on phytoplankton community composition and succession. The phytoplankton community was composed predominantly of haptophytes in phase I, prasinophytes, dinoflagellates, and cryptophytes in phase II, and haptophytes, prasinophytes, dinoflagellates and chlorophytes in phase III (Schulz et al., 2013. Increasing ambient inorganic carbon concentrations have also been shown to promote primary production and carbon assimilation. For this study, it is

    Transuranic elements in fallout are generally bound in oxide particles, size from submicron to several microns. During the fallout they can be intercepted on plant covers or reach the soil surface. The particles can be re-suspended to the air and reach other residence sites, be linked into the food chain or be redistributed in other ways (Cf Essington et al. 1976) before eventually being incorporated into the soil. The fate of such particles in the soil depends on the size and on the nature of the particulate matter and on environmental factors, the climate and the properties of the soil. In a dry climate the particles tend to be kept intact long time, (Schulz et al. 1976) and they are more easily redistributed than in a humid climate with plant covered moist and living soils. In the former the particles move more easily in the soil profile than in the latter, the particle matter is very slowly dissolved and the average availability of the deposited nuclides for plant uptake can be assumed to be comparatively low. The downward movements of the particles or nuclide compounds bound to small soil particles are enhanced by the swelling and shrinking of soil caused by absorption and depletion of water during the season. Cracks and fissures are created and closed several times a year in soils rich in colloidal material. Sandy soils with coarse material have less cracks, but in dry conditions the empty pore space may allow transport of fine particles. The coarser material also has less specific area and sorption capacity. The nuclide compounds leached with the drainage water in coarse soils should be less retarded than in clays (Cf. Rai and Serne, 1977; Nishita and Haug, 1979 and Rai et al., 1980). The lysimeter installation used for the study reported below was primarily designed to study the plant uptake of transuranics from a number of Swedish soils. However, as such an installation in many ways well simulate field conditions and at the same time is a closed system

    Full Text Available Recent phylogenetic studies on Nematinae based on DNA sequences have shown extensive incongruencies with current nomenclature of genus-group taxa. Here, we expand previous DNA sequence datasets based on three genes (CoI, Cytb, and EF-1α, to include a fourth (NaK and more genera. The analyses largely confirm the previous findings, particularly the existence of two well-supported large clades, Euura and Pristiphora, together comprising more than 75% of the species of Nematinae. Basal relationships within these two clades remain poorly resolved, mirroring the difficulties in delimiting genera based on morphology. In addition, a moderately supported small clade, Nematus, is found. The relationships between the Euura, Pristiphora, and Nematus clades are uncertain. Therefore, to stabilize the nomenclature we treat these clades as genera. This taxonomic treatment results in numerous new combinations of species names. The following synonymies are proposed for the available genus-group names.

    Clinical features of 147 patients with biopsy-proven thyroid carcinomas were investigated from January, 1972 to April, 1978 at the Seoul National University Hospital with the following results. 1) The incidence of thyroid carcinomas according to their histopathological classification revealed 76.2% of papillary carcinoma, 19.0% of follicular carcinoma, and 3 cases of occult sclerozing carcinoma, 1 case of giant cell carcinoma and 1 case of metastatic melanoma. 2) The ratio of male to female patients was 1:8.3 and showed no difference between papillary and follicular carcinomas. 3) The age distribution showed the peak incidence in the fourth decade (29.3%) followed by the fifth and sixth decades. 4) The average duration of illness from the onset of symptoms was about 5 years while it was 4.4 years and 7.6 years in the papillary and follicular carcinomas respectively. 5) The diameter of the thyroid masses was smaller than 5 cm in 53.6% of the patients, from 5 cm to 10 cm in 40.0% and larger than 10 cm in 6.4%. 6) In 36.4% of the patients with thyroid carcinomas the thyroid masses were fixed to adjacent tissues. 7) Metastasis to the regional lymph nodes was noted in 40.0% of the total cases, and in 45.2% and 17.6% of the papillary and follicular carcinomas respectively, while the lung and bone metastases were found in 10.0% and 4.4% in each type respectively. 8) 88.9% of the patients showed cold areas in the thyroid scans using {sup 131}I. 9) Typical psammoma bodies were observed in 21.3% of the cases in the microscopic examination of the pathological specimens. 10) The initial diagnosis of thyroid malignancy could be made before histological confirmation in 64.5% of the patients. 11) The clinical staging slightly modified from Schulz method revealed 43.6% of the patients in stage I, 26.4% in stage II, 20.9% in stage III and 9.1% in stage IV. 12) The association with Hashimoto's thyroiditis was noted in 4 cases, with nodular goiter in 3 cases, and with follicular

    Partners are a significant influence on individuals' health, and concordance in health behaviours increases over time in couples. Several theories suggest that couple-focused interventions for health behaviour change may therefore be more effective than individual interventions. A systematic review of health behaviour change interventions for couples was conducted. Systematic search methods identified randomized controlled trials (RCTs) and non-randomized interventions of health behaviour change for couples with at least one member at risk of a chronic physical illness, published from 1990-2014. We identified 14 studies, targeting the following health behaviours: cancer prevention (6), obesity (1), diet (2), smoking in pregnancy (2), physical activity (1) and multiple health behaviours (2). In four out of seven trials couple-focused interventions were more effective than usual care. Of four RCTs comparing a couple-focused intervention to an individual intervention, two found that the couple-focused intervention was more effective. The studies were heterogeneous, and included participants at risk of a variety of illnesses. In many cases the intervention was compared to usual care for an individual or an individual-focused intervention, which meant the impact of the couplebased content could not be isolated. Three arm studies could determine whether any added benefits of couple-focused interventions are due to adding the partner or specific content of couple-focused interventions. Statement of contribution What is already known on this subject? Health behaviours and health behaviour change are more often concordant across couples than between individuals in the general population. Couple-focused interventions for chronic conditions are more effective than individual interventions or usual care (Martire, Schulz, Helgeson, Small, & Saghafi, ). What does this study add? Identified studies targeted a variety of health behaviours, with few studies in any one area. Further

    2017-10-01

    The task of naming planetary surface features, rings, and natural satellites is managed by the International Astronomical Union’s (IAU) Working Group for Planetary System Nomenclature (WGPSN). There are currently 15,361 IAU-approved surface feature names on 41 planetary bodies, including moons and asteroids. The members of the WGPSN and its task groups have worked since the early 1970s to provide a clear, unambiguous system of planetary nomenclature that represents cultures and countries from all regions of Earth. WGPSN members include Rita Schulz (Chair) and 9 other members representing countries around the globe. The participation of knowledgeable scientists and experts in this process is vital to its success of the IAU WGPSN . Planetary nomenclature is a tool used to uniquely identify features on the surfaces of planets or satellites so they can be located, described, and discussed in publications, including peer-review journals, maps and conference presentations. Approved names are listed in the Transactions of the IAU and on the Gazetteer of Planetary Nomenclature website. Any names currently in use that are not listed the Gazetteer are not official. Planetary names must adhere to rules and conventions established by the IAU WGPSN (see http://planetarynames.wr.usgs.gov/Page/Rules for the complete list). The gazetteer includes an online Name Request Form (http://planetarynames.wr.usgs.gov/FeatureNameRequest) that can be used by members of the professional science community. Name requests are first reviewed by one of six task groups (Mercury, Venus, Moon, Mars, Outer Solar System, and Small Bodies). After a task group has reviewed a proposal, it is submitted to the WGPSN. Allow four to six weeks for the review and approval process. Upon WGPSN approval, names are considered formally approved and it is then appropriate to use them in publications. Approved names are immediately entered into the database and shown on the website.

  7. Lagrangian modelling of ocean surface waves and synthetic aperture radar wave measurements

    Energy Technology Data Exchange (ETDEWEB)

    Fouques, Sebastien

    2005-07-01

    The present thesis is concerned with the estimation of the ocean wave spectrum from synthetic aperture radar imaging and the modelling of ocean surface waves using the Lagrangian formalism. The first part gives a short overview of the theories of ocean surface waves and synthetic aperture radar (SAR) whereas the second part consists of five independent publications. The first two articles investigate the influence of the radar backscatter model on the SAR imaging of ocean waves. In Article I, Monte Carlo simulations of SAR images of the ocean surface are carried out using a nonlinear backscatter model that include both specular reflection and Bragg scattering and the results are compared to simulations from the classical Hasselmann integral transform (Hasselmann and Hasselmann, 1991). It is shown that nonlinearities in the backscatter model strongly influence the imaging of range-travelling waves and that the former can suppress the range-splitting effect (Bruning et al., 1988). Furthermore, in Article II a database of Envisat-ASAR Wave Mode products co-located with directional wave spectra from the numerical model WAM and which contains range-travelling wave cases only, is set up. The WAM spectra are used as input to several ocean-to-SAR integral transforms, with various real aperture radar (RAR) models and the obtained SAR image cross-spectra are compared to the Envisat-ASAR observations. A first result is that the use of a linear backscatter model leads to a high proportion of non-physical negative backscatter values in the RAR image, as suggested by Schulz-Stellenfleth (2001). Then, a comparison between the observed SAR cross-spectra and the ones simulated through Hasselmann's integral transform reveals that only twenty percents of the observations show a range-splitting effect as strong as in the simulations. A much better agreement is obtained when using the integral transform by Schulz-Stellenfleth (2003), which is based on a nonlinear hackscatter model

Until now, in situ instrumentation was designed to detect and determine concentrations of a wide number of organic biomarkers. The relevant method which was and still is employed in missions dedicated to the quest of life (from Viking to ExoMars) corresponds to the pyrolysis-GC-MS. Along the missions, this approach has been significantly improved in terms of extraction efficiency and detection with the use of chemical derivative agents (e.g. MTBSTFA, DMF-DMA, TMAH…), and in terms of analysis sensitivity and resolution with the development of in situ high-resolution mass spectrometer (e.g. TOF-MS). Thanks to such an approach, organic compounds such as amino acids, sugars, tholins or polycyclic aromatic hydrocarbons (PAHs) were expected to be found. However, while there’s a consensus that the GC-MS of Viking, Huygens, MSL and MOMA space missions worked the way they had been designed to, pyrolysis is much more in debate (Glavin et al. 2001; Navarro-González et al. 2006). Indeed, (1) it is thought to remove low levels of organics, (2) water and CO2 could interfere with the detection of likely organic pyrolysis products, and (3) only low to mid-molecular weight organic molecules can be detected by this technique. As a result, researchers are now focusing on other in situ techniques which are no longer based on the volatility of the organic matter, but on the liquid phase extraction and analysis. In this line, micro-fluidic systems involving sandwich and/or competitive immunoassays (e.g. LMC, SOLID; Parro et al. 2005; Sims et al. 2012), micro-chip capillary electrophoreses (e.g. MOA; Bada et al. 2008), or nanopore-based analysis (e.g. BOLD; Schulze-Makuch et al. 2012) have been conceived for in situ analysis. Thanks to such approaches, molecular biological polymers (polysaccharides, polypeptides, polynucleotides, phospholipids, glycolipids

    sequence from the newly-named Lake Tiercelin (2m-long) was recovered using UWITEC gravity coring equipment operated from a portable rubber boat by 54m water-depth. Those three sequences cover the whole Holocene periods. The 3m-long sequence taken in Lake Guynemer, Loranchet peninsula, was taken using a homemade small platform and a Nesje piston corer by 50m water-depth and covers the last 5 ka cal. BP. Two additional lakes were cored in the vicinity of Lake Armor: Fougères and Poule from which short sequences were taken in order to study environmental changes since the arrival of humans in the 18th century and the subsequent introduction of exogenous plant and animal species. We present here preliminary results including the dating of all sediment sequences as well as their chemical logging and sedimentological description. This already revealed the recurrence of Holocene volcanic eruptions as well as erosion patterns that are comparable among different records. The recognition of tephra layers will further allow the synchronization of terrestrial records together and with marine records around Kerguelen Archipelago. Paleoclimate interpretations of acquired data as well as further measurements are still ongoing processes. However, one may already argue that we collected rare geological sequences of prime importance in the quest of understanding climate patterns affecting the southern high latitudes all along the Holocene. 1.

We tested 2 Web-based computer-tailored physical activity intervention versions (mHealth and eHealth) against a control condition with regard to efficacy, use, usability, and appreciation. The overall effect was mainly caused by the more effective eHealth intervention. The mHealth app was rated inferior to the eHealth version with regard to usability and appreciation. More research is needed to assess how both methods can complement each other.

    framework model are interpreted seismic lines, 3d-models can be generated either in time or in depth domain. Some partners will build their 3d-model in time domain and convert it after finishing to depth. Other participants will transform seismic information first and will model directly in depth domain. To ensure comparability between the different parts transnational velocity models for time-depth conversion are required at an early stage of the project. The exchange of model geometries, topology, and geo-scientific content will be achieved applying an appropriate cyberinfrastructure called GST. It provides functionalities to ensure semantic and technical interoperability. Within the project GeoMol a web server for the dissemination of 3d geological models will be implemented including an administrative interface for the role-based access, real-time transformation of country-specific coordinate systems and a web visualisation features. The project GeoMol is co-funded by the Alpine Space Program as part of the European Territorial Cooperation 2007-2013. The project integrates partners from Austria, France, Germany, Italy, Slovenia and Switzerland and runs from September 2012 to June 2015. Further information on www.geomol.eu.

  15. Comet Dust After Deep Impact

    When the Deep Impact Mission hit Jupiter Family comet 9P/Tempel 1, an ejecta crater was formed and an pocket of volatile gases and ices from 10-30 m below the surface was exposed (A Hearn et aI. 2005). This resulted in a gas geyser that persisted for a few hours (Sugita et al, 2005). The gas geyser pushed dust grains into the coma (Sugita et a1. 2005), as well as ice grains (Schulz et al. 2006). The smaller of the dust grains were submicron in radii (0-25.3 micron), and were primarily composed of highly refractory minerals including amorphous (non-graphitic) carbon, and silicate minerals including amorphous (disordered) olivine (Fe,Mg)2SiO4 and pyroxene (Fe,Mg)SiO3 and crystalline Mg-rich olivine. The smaller grains moved faster, as expected from the size-dependent velocity law produced by gas-drag on grains. The mineralogy evolved with time: progressively larger grains persisted in the near nuclear region, having been imparted with slower velocities, and the mineralogies of these larger grains appeared simpler and without crystals. The smaller 0.2-0.3 micron grains reached the coma in about 1.5 hours (1 arc sec = 740 km), were more diverse in mineralogy than the larger grains and contained crystals, and appeared to travel through the coma together. No smaller grains appeared at larger coma distances later (with slower velocities), implying that if grain fragmentation occurred, it happened within the gas acceleration zone. These results of the high spatial resolution spectroscopy (GEMINI+Michelle: Harker et 4. 2005, 2006; Subaru+COMICS: Sugita et al. 2005) revealed that the grains released from the interior were different from the nominally active areas of this comet by their: (a) crystalline content, (b) smaller size, (c) more diverse mineralogy. The temporal changes in the spectra, recorded by GEMIM+Michelle every 7 minutes, indicated that the dust mineralogy is inhomogeneous and, unexpectedly, the portion of the size distribution dominated by smaller grains has

We report a consecutive case series using this method as the primary treatment line. The rationale for this study was to evaluate the midterm results of this method in a prospective and consecutive case series. The primary study question was to determine the clinical results 24–36 months after primary anterior cruciate ligament (ACL reconstruction using a bone plug-free quadriceps tendon autograft fixed with bioabsorbable cross-pins. Materials and methods: The study population included 55 patients, of whom 24 were female (43.6%. The mean age at the index procedure was 31.7 years (15–58 years. All patients received an ACL construction using a bone block-free quadriceps tendon graft fixed with resorbable cross-pins. The postoperative regimen included partial weight-bearing for 3 weeks and flexion limited to 90° for six weeks; an orthosis was not used. The mean follow-up duration was 29.5 months (24.3–38.5 months after the index procedure. The International Knee Documentation Committee (IKDC subjective score and examination form was assessed, as well as the Lysholm and Gillquist score and the Tegner activity index. The Rolimeter arthrometer was used to assess the anterior laxity of the knee. Results: Graft harvesting was possible in all cases

    simultaneously with IP measurements. The low-resistivity zones coincide with the altered and sheared acidic meta-volcanics. The quantitative interpretation technique determined the conductive bodies' parameters using the Schulz method (1985) where the depth to the top of the ore body ranged from 21 to 62 m while the maximum width ranged from 52 to 165 m. The induced polarization-chargeability data were measured in the time domain. The positive anomalies on the IP-chargeability map coincide with the sites of alterations, shears and contact zones. Four dipole–dipole sections were carried out along the anomalous sites selected from the constructed maps in the study area and were inverted using the RES2DINV program. The results of resistivity and IP inversions indicated that there are conductive and chargeable bodies at depths ranging from 15 to 65 m. According to the integrated geophysical results, two suggested borehole sites were selected before carrying out any future mining projects

    consisting of two pairs of stars, called HD 98800A and HD 98800B. These pairs, each of which is about an Earth-Sun distance apart, orbit each other at about the same distance as Pluto orbits the Sun. "Our X-ray results are fully consistent with other observations that show that accretion of matter from a disk in HD 98800A has dropped to a low level," said Kastner. "So Chandra has thrown new weight behind the evidence that any disk in this system has been greatly diminished or destroyed in ten million years, perhaps by the ongoing formation of planets or by the companion stars." The new X-ray technique for studying disks around stars relies on the ability of Chandra's spectrometers to measure the energies of individual X-rays very precisely. By comparing the number of X-rays emitted by hot gas at specific energies from ions such as oxygen and neon, the temperature and density of particles can be determined. This new technique will help astronomers to distinguish between an accretion disk and a stellar corona as the origin of intense X-ray emission from a young star.

    2009-01-01

    In order to explore the reasons for the apparent discrepancy between laboratory and field weathering rates and to determine the extent to which weathering rates are controlled by the approach to thermodynamic equilibrium, secondary mineral precipitation, and flow rates, a multicomponent reactive transport model (CrunchFlow) was used to interpret soil profile development and mineral precipitation and dissolution rates at the 226 ka Marine Terrace Chronosequence near Santa Cruz, CA. Aqueous compositions, fluid chemistry, transport, and mineral abundances are well characterized [White A. F., Schulz M. S., Vivit D. V., Blum A., Stonestrom D. A. and Anderson S. P.

I: interpreting the long-term controls on chemical weathering based on spatial and temporal element and mineral distributions. Geochim. Cosmochim. Acta 72 (1), 36-68] and were used to constrain the reaction rates for the weathering and precipitating minerals in the reactive transport modeling. When primary mineral weathering rates are calculated with either of two experimentally determined rate constants, the nonlinear, parallel rate law formulation of Hellmann and Tisserand [Hellmann R. and Tisserand D. (2006) Dissolution kinetics as a function of the Gibbs free energy of reaction: An experimental study based on albite feldspar. Geochim. Cosmochim. Acta 70 (2), 364-383] or the aluminum inhibition model proposed by Oelkers et al. [Oelkers E. H., Schott J. and Devidal J. L. (1994) The effect of aluminum, pH, and chemical affinity on the rates of aluminosilicate dissolution reactions. Geochim. Cosmochim. Acta 58 (9), 2011-2024], modeling results are consistent with field-scale observations when independently constrained clay precipitation rates are accounted for. Experimental and field rates, therefore, can be reconciled at the Santa Cruz site. Additionally, observed maximum clay abundances in the argillic horizons occur at

    The article presents process of shaping place identity on the example of an important for Pomerania region investment - European Solidarity Centre. The idea of a Solidarity social movement is strongly associated with the formation of post-socialist national identity of Poland as well as local identity of Pomerania, from which movement originates. The realization of the European Solidarity Centre aims to be one of the essential elements of shaping Gdańsk’s identity of space. The article is an attempt to analyse how the presence of realization gradually affects the formation of the place identity of new urban space. Analysis of this realization will allow on the one hand to verify design assumptions made by authors, on the other provides the opportunity to search for best description of still vague notion of local identity. This concept, though intuitively close to everyone still seems to elude conceptual apparatus of theory of architecture. The intention of this article is to explore the notion of identity based on the observations of the newly realized significant cultural space. This analysis approaches the concept of identity from two perspectives. The first approach draws from the concept of identity of Christian Norberg-Schulz. Here, local identity is seen as a unique set of characteristics of space. So seen the concept of place identity is a correlate of concept of personal identity. In this analysis, methods of description of personal identity were transferred to the identity of the place. In the second approach, the identity of place is understood as a unique for that place way of being in space, way to spend time and development of the site-specific urban rituals. Such a concept of identity, draws from the concept of place of Kim Dovey. Both presented approaches seems to complement each other but they also emphasize different qualities. The now-traditional concept of Genius Loci sees architecture as a structural system of meanings. Meaningful elements

Therefore, the aims of our study were 1 to develop an instrument to evaluate the usage of the standardized MP, 2 to assess if patients can locate, and 3 understand important information. Moreover, we explored patients’ opinion and suggestions regarding the standardized MP template.Patients and methods: We conducted a cross-sectional study to evaluate the practical handling of the standardized MP. We interviewed 40 adult patients in seven community pharmacies in Germany, who took at least five medicines regularly and gave their written informed consent. The interview consisted of questions regarding finding and understanding information provided on a mock-up MP, patients’ opinion and the execution of the information on the MP by filling pill boxes. We eventually developed a new evaluation method to quantify the practical handling of the MP by rating the pill boxes filled by the patients.Results: Overall, the participants rated the MP positively. Thirty-nine (98% participants found important information on a mock-up standardized MP. Patients were questioned to identify if they understood information on medical intake as it relates to meals. In particular, they were questioned about medicine intake “1 hour before a meal”, which 98% (n=39 interpreted correctly, and “during a meal”, which 100% (n=40

    observed up to 30 GPa without any discontinuity and their pressure behaviour (dν/dP) can well be described by linear fits. Molecular vibrations are very sensitive to non-hydrostatic conditions and we interpret the disappearance of the OH-bands as a stress-induced proton disordering in hydrous ringwoodite due to the use of hard pressure transmiting media like CsI or argon without thermal annealing. Thus, our study cannot confirm the phase transition observed by Camorro Perez et al. (2006) in ringwoodite. But as they used Neon as pressure transmitting medium, which is known to become non-hydrostatic at pressure above 16 GPa (Bell and Mao, 1981) we argue that their observation of a sudden disappearance of the OH band may also be related to non-hydrostatic conditions.

    We performed Miller-Urey type experiments to determine the organic synthesis of amino acids under conditions that have likely occurred on Saturn's moon Titan and are also relevant to Jupiter's moon Europa. We conducted the first set of experiments under early Earth conditions, similar to the original Miller-Urey experiments (Miller, 1953). In brief, the 250ml round bottom flask was filled with approximately 200mL of filtered sterile water and the apparatus was placed under vacuum for 10 minutes to purge the water of gases. The system was then flushed with hydrogen gas and placed under vacuum three times. Gases were then added in the following order: hydrogen gas to 0.1 bar, methane gas to 0.45 bar and ammonia to 0.45 bar ( 1bar total). The water was then brought to a boil and the spark was applied using the tesla coil up to a maximum of 50,000 volts. The apparatus was run for approximately 5-7 days. Between the runs the apparatus was cleaned using a hot 10% sodium hydroxide solution followed by a dilute sulfuric acid wash and four rinses with Millipure water. In the second set of experiments we simulated conditions that could have existed on an early, warm Titan or after an asteroid strike on Titan (Schulze-Makuch and Grinspoon, 2005), particularly if the strike would have occurred in the subpolar areas that exhibit vast ethane-methane lakes. If the asteroid or comet would be of sufficient size, it would also puncture the icy crust and access a vast reservoir of the subsurface liquid ammonia-water mixture. Thompson and Sagan (1992) showed that a liquid water-ammonia body could exist for millions of years on Titan after an asteroid impact. Thus, we modified the experimental conditions as described above and report on the results. Assuming a moderate impact in the subpolar areas of Titan, we used an atmosphere of currently 1.5 bar, but increased the partial pressure of methane to 1 bar (and 0.1 bar ammonia assuming a minor amount of ammonia-water ice being evaporated

  9. Quantification and Negation in Event Semantics

    Full Text Available Recently, it has been claimed that event semantics does not go well together with quantification, especially if one rejects syntactic, LF-based approaches to quantifier scope. This paper shows that such fears are unfounded, by presenting a simple, variable-free framework which combines a Neo-Davidsonian event semantics with a type-shifting based account of quantifier scope. The main innovation is that the event variable is bound inside the verbal denotation, rather than at sentence level by existential closure. Quantifiers can then be interpreted in situ. The resulting framework combines the strengths of event semantics and type-shifting accounts of quantifiers and thus does not force the semanticist to posit either a default underlying word order or a syntactic LF-style level. It is therefore well suited for applications to languages where word order is free and quantifier scope is determined by surface order. As an additional benefit, the system leads to a straightforward account of negation, which has also been claimed to be problematic for event-based frameworks.ReferencesBarker, Chris. 2002. ‘Continuations and the nature of quantification’.

    Full Text Available Introduction: The economical yield of date fruits depends on many factors (Al-Shahib and Marshall, 2003. One of them is harvesting in optimum stage. Generally, date fruits have four distinct stages of ripeness to satisfy different consumption requirements (e.g., fresh and processed. They are known throughout the world by their Arabic names which are Kimri, Khalal, Rutab and Tamr in order of ripeness (Imad and Abdul Wahab, 1995; Al-Shahib and Marshall, 2003; Sahari et al., 2007. Decreasing moisture content and increasing sugar content happens gradually while the date ripeness approaches to Tamr stage. From Kimri to Khalal stage, the size and acidity decreases when the color of Mazafati variety changes from green to red. The change in acidity continues from Rutab to Tamr stage while color transforms from brown to black. At the final stage of ripeness, Mazafati variety is soft and has a good storability (Al-Shahib and Marshall, 2003. The main Raman techniques commonly applied in agricultural product and food analyzing include dispersive Raman spectroscopy, Fourier Transform (FT, Raman spectroscopy, Surface-Enhanced Raman Spectroscopy (SERS and Spatially Offset Raman Spectroscopy (SORS. Synytsya et al. (2003 illustrated that FT-Raman spectroscopy is a valuable tool in structural analysis of commercial citrus and sugar beet pectin. Yang and Irudayaraj (2003 employed an FT-Raman approach to detect and classify foodborne microorganisms on the whole apple surface for the first time. Schulz et al., (2005 revealed the potential of FT-Raman spectroscopy in natural carotenoid analysis. Also, many researchers have attempted to apply FT-Raman spectra on the whole fruits and vegetables. FT-Raman spectroscopy was used by Veraverbeke et al. (2005 to evaluate the natural, intact wax layers on the surface of whole fruits. Nikbakht et al. (2011 used a FT-Raman spectroscopy for qualitative and quantitative analysis of tomato ripeness parameters. The scope of this

    course depend on the exact moments of the impacts. Also at the time of the impacts, a group of French astronomers, headed by Bruno Sicardy of the Observatoire de Paris, will mount a special CCD camera at the Danish telescope, which will be used for different types of observations. They also hope to be able to detect some of the expected light flashes from the Jupiter moons. In addition, this programme will monitor changes in the cloud structure around the impact sites. It may also be possible to obtain low-resolution spectra which will show the temperature of the flashes, but in view of their very short duration, a few seconds at most, this will not be easy. The same instrument will also be used by Nick Thomas of the Max-Planck-Institut fur Aeronomie (Lindau, Germany) to image the Jupiter plasma torus in order to detect possible changes after the impacts. Spectral observations of the comet will be made with the ESO 1.5 m telescope in April by Heike Rauer, also from the Max-Planck-Institut fur Aeronomie. They are expected to lead to a better knowledge about the physical and chemical state of the impacting bodies. For instance, are they really so ``dusty'', as present observations seem to indicate, or do they contain large amounts of gas ? If so, what kind of molecules are present ? This will help to refine the predictions of the impact effects. Imaging and spectral observations of the comet for the same general purposes will also be obtained in early July with the EMMI instrument at the 3.5 m New Technology Telescope by an international team headed by Rita Schulz, formerly at the University of Maryland and now at the Max-Planck-Institut fur Aeronomie. No less than 46 observing hours have been allocated at the Swedish-ESO Submillimetre Telescope (SEST) to an international group headed by Daniel Gautier, Observatoire de Paris-Meudon. During the impacts, the cometary molecules will be mixed with those in the Jovian atmosphere, some of which may come from very deep layers
