Directory of Open Access Journals (Sweden)

Diana Schmidt-Pfister

2011-03-01

Full Text Available This edited volume comprises a range of studies that have employed a group discussion technique in combination with a specific strategy for reconstructive social research—the so-called documentary method. The latter is an empirical research strategy based on the meta-theoretical premises of the praxeological sociology of knowledge, as developed by Ralf BOHNSACK. It seeks to access practice in a more appropriate manner, namely by differentiating between various dimensions of knowledge and sociality. It holds that habitual collective orientations, in particular, are best accessed through group discussions. Thus this book does not address the group discussion technique in general, as might be expected from the title. Instead, it presents various contributions from researchers interpreting transcripts of group discussions according to the documentary method. The chapters are grouped into three main sections, representing different frameworks of practice and habitual orientation: childhood, adolescence, and organizational or societal context. A fourth section includes chapters on further, potentially useful ways of employing this particular technique and approach, as well as a chapter on teaching it in a meaningful way. Each chapter is structured in the same way: introduction to the research field and focus; methodological discussion; exemplary interpretation of group discussions; and concluding remarks. Whilst the transcripts referred to by the authors are very helpfully presented in the chapters, there is a lack of methodological reflection on the group discussion technique itself, which, as mentioned above, is only evaluated in regard to the documentary method.

The majority of these genes had not previously been annotated. A subset of the predicted peptides show high overall sequence...... similarity to Rapid Alkalinization Factor (RALF), a peptide isolated from tobacco. We therefore refer to this peptide family as RALFL for RALF-Like. RT-PCR analysis confirmed that several of the Arabidopsis genes are expressed and that their expression patterns vary.

Coherent optical transients observed in rubidium atomic line filtered Doppler velocimetry experiments

Energy Technology Data Exchange (ETDEWEB)

Fajardo, Mario E., E-mail: mario.fajardo@eglin.af.mil; Molek, Christopher D.; Vesely, Annamaria L. [Air Force Research Laboratory, Munitions Directorate, Ordnance Division, Energetic Materials Branch, AFRL/RWME, 2306 Perimeter Road, Eglin AFB, Florida 32542-5910 (United States)

We report the first successful results from our novel Rubidium Atomic Line Filtered (RALF) Doppler velocimetry apparatus, along with unanticipated oscillatory signals due to coherent optical transients generated within pure Rb vapor cells. RALF is a high-velocity and high-acceleration extension of the well-known Doppler Global Velocimetry (DGV) technique for constructing multi-dimensional flow velocity vector maps in aerodynamics experiments [H. Komine, U.S. Patent No. 4,919,536 (24 April 1990)]. RALF exploits the frequency dependence of pressure-broadened Rb atom optical absorptions in a heated Rb/N{sub 2} gas cell to encode the Doppler shift of reflected near-resonant (λ{sub 0} ≈ 780.24 nm) laser light onto the intensity transmitted by the cell. The present RALF apparatus combines fiber optic and free-space components and was built to determine suitable operating conditions and performance parameters for the Rb/N{sub 2} gas cells. It yields single-spot velocities of thin laser-driven-flyer test surfaces and incorporates a simultaneous Photonic Doppler Velocimetry (PDV) channel [Strand et al., Rev. Sci. Instrum. 77, 083108 (2006)] for validation of the RALF results, which we demonstrate here over the v = 0 to 1 km/s range. Both RALF and DGV presume the vapor cells to be simple Beer's Law optical absorbers, so we were quite surprised to observe oscillatory signals in experiments employing low pressure pure Rb vapor cells. We interpret these oscillations as interference between the Doppler shifted reflected light and the Free Induction Decay (FID) coherent optical transient produced within the pure Rb cells at the original laser frequency; this is confirmed by direct comparison of the PDV and FID signals. We attribute the different behaviors of the Rb/N{sub 2} vs. Rb gas cells to efficient dephasing of the atomic/optical coherences by Rb-N{sub 2} collisions. The minimum necessary N{sub 2} buffer gas density ≈0.3 amagat translates into a

These are the proceedings of the Second R. Yorque Workshop on Resource Management which took place in Ashland, Oregon on July 23-25, 1984. The purpose of the workshop is to provide an informal atmosphere for the discussion of resource assessment and management problems. Each participant presented a one hour morning talk; afternoons were reserved for informal chatting. The workshop was successful in stimulating ideas and interaction. The papers by R. Deriso, R. Hilborn and C. Walters all address the same basic issue, so they are lumped together. Other than that, the order to the papers in this volume was determined in the same fashion as the order of speakers during the workshop -- by random draw.

Full Text Available This article highlights the foremost landmarks in the life and work of a prominent expert in the field of physical education and sport, an active participant of the Olympic Games revival and one of the members of the 1st International Olympic Committee Alexey Butovsky. His military career from a cadet and non-commissioned officer to lieutenant-general is outlined, and his activities in the field of theory and practice of physical education both in Russia and on his trips abroad, which was aimed at study, generalization and further application of the best experience accumulated in that area in different countries, are presented, as well. A. Butovsky's acquaintance with P. de Coubertin and their closer relations resulted in Alexey Butovsky's involvement in the preparation and participation of the founding congress in 1894 in Paris is particularly noted, as well as the Congress that adopted important decisions on the revival of the Olympic Games and creation of the International Olympic Committee, in which General Butovsky was introduced among its first members. There has been studied his activity not only as a member of the IOC, but his doings after his retirement from the membership of this international organization, as well.

On the Origins of the Lubok Text The Register of Dames and Handsome Maidens

Directory of Open Access Journals (Sweden)

Alexandra A. Pletneva

2015-08-01

Full Text Available This article is devoted to the attempts to identify the prototype and the sources of The Register of Dames and Handsome Maidens, which was part of the lubok tradition of the 17th–18th centuries. This text is a list of female proper names provided with humorous commentaries. The satirical texts of the 17th century frequently replicate the structure of the documents and literary texts of those times. Some satirical texts represent the structure of church services, an alphabet prayer, a petition, etc. Among the manuscript and lubok texts of the 17th–18th centuries, there is a significant number of texts which include lists of names with humorous characteristics. These texts may be dated back to the Old Russian dictionaries of proper names, e.g., the Commentaries on the Names in Alphabetical Order by Maximus the Greek. Unlike the other texts organized as lists of names, The Register of Dames is related to the wedding ritual, and its probable source can be identified as the register of potential brides for Tsar Alexey Mikhailovich, which was compiled in 1669-1670, when Tsar Alexey was planning to marry for a second time. The text of the Register includes all but two of the names that appear in the probable prototype, including rather rare names. Furthermore, the name Natalia—that is, the tsar’s future wife—is particularly emphasized.

Full Text Available The "Founding fathers" of American Studies at MGIMO are considered to be A.V. Efimov and L.I. Clove. Alexey Efimov - Corresponding Member of the USSR Academy of Sciences since 1938, Head of the Department of Modern and Contemporary History and Dean of the Historical School at the Moscow State University - one of the first professors of the Faculty of International Relations MGIMO. Efimov distinguished himself by a broad vision and scope of scientific interests. Back in 1934 he published a monograph "On the history of capitalism in the United States," which initiated a series of research culminating in the fundamental work "The United States. The path of capitalist development (pre-imperialist era". Alexey was not only a great scientist but also a great teacher, whose lectures was popular throughout Moscow. His lecture courses, given at the end of the 1940s at MGIMO, became the basis for the first post-war history textbooks USA - "Essays on the history of the United States." At least as colorful a figure was Professor Leo Izrailevich Zubok - a man of unusual destiny. As a teenager he emigrated to the United States with his parents, where he soon joined the American revolutionary movement in the 1920s and was forced to leave the country. He came to MGIMO being already an experienced scientists. His research interests were very wide: from the study of American foreign policy expansion to the history of the labor movement in the United States. Zubok's fundamental works still have not lost its scientific significance. He has successfully combined scientific work with teaching. Tutorials that are based on his lectures were very popular not only among students of MGIMO.

Misunderstanding Abai and the legacy of the canon: “Neponyatnii” and “Neponyatii” Abai in contemporary Kazakhstan

Directory of Open Access Journals (Sweden)

Full Text Available The Soviet canonisation of Abai, the nineteenth-century Kazakh poet and enlightener became a problematic theme for local intellectuals in the 2010s after the Occupy Abai movement in Moscow raised concerns over the heritage of Abai as a Sovietised canon and as an independent non-Soviet thinker. In 2012 oppositional leaders in Russia occupied Abai monument in Moscow and the leader of the opposition Alexey Navalny, called for his supporters to gather around the monument to unknown strange Kazakh guy using the Russian slang word – neponyatnii Kazakh. Local audience in Kazakhstan at first responded with offensive comments and questions to the Russian opposition movement – how come Abai, the Kazakh version of Russian poet and a visionary Alexander Pushkin, the symbol and canon of Soviet Kazakh literature and the symbol of post-Soviet Kazakhness and its culture could be unknown and strange? From the celebrated writer of the Soviet dekadas and Leninist prizes for Mukhtar Auezov's novel The Path of Abai (Abai Zholy Abai turned into neponyatnii – incomprehensible, strange (in words of Russian Alexey Navalny and neponyatii – misunderstood poet. These discussions on popular online Russophone as well as Kazakhophone platforms and blogs opened up a debate on the legacy and problematic canonisation of Abai. Is Abai misunderstood in contemporary Kazakhstani society? From short essays when famous writer Gerold Belger speaks to Abai's monument in central Almaty to mobile phone applications featuring Abai's Qara Sozder, to the famous anonymous Abai graffiti in central Almaty and Occupy Abai movement responses in Kazakh internet sphere, I trace the mutations of Abai's canon. These discussions reveal the conflicting trends of young Kazakhs and Kazakhstanis who take their cultural criticisms online but continue using the “national” frameworks in their globalized discussions.

Exotic species with explicit noble metal-noble gas-noble metal linkages.

We present a study of the isoelectronic Pt 2 Ng 2 F 4 and [Au 2 Ng 2 F 4 ] 2+ species with noble gas atoms (Ng = Kr, Xe, Rn) acting as links bridging the two noble metal atoms. The stability of the species is investigated using several thermodynamic, kinetic and reactivity indicators. The results are compared against [AuXe 4 ] 2+ , which is thermodynamically unstable in the gas phase but is stabilized in the solid state to the point that it has been experimentally detected as [AuXe 4 ](Sb 2 F 11 ) 2 (S. Seidel and K. Seppelt, Science, 2000, 290, 117-118). Our results indicate that improving upon [AuXe 4 ] 2+ , these exotic combinations between the a priori non-reactive noble metals and noble gases lead to metastable species, and, therefore, they have the possibility of existing in the solid state under adequate conditions. Our calculations include accurate energies and geometries at both the CCSD/SDDALL and MP2/SDDALL levels. We offer a detailed description of the nature of the bonding interactions using orbital and density-based analyses. The computational evidence suggests partially covalent and ionic interactions as the stabilization factors.

Automatic SIMD vectorization of SSA-based control flow graphs

CERN Document Server

Karrenberg, Ralf

2015-01-01

Ralf Karrenberg presents Whole-Function Vectorization (WFV), an approach that allows a compiler to automatically create code that exploits data-parallelism using SIMD instructions. Data-parallel applications such as particle simulations, stock option price estimation or video decoding require the same computations to be performed on huge amounts of data. Without WFV, one processor core executes a single instance of a data-parallel function. WFV transforms the function to execute multiple instances at once using SIMD instructions. The author describes an advanced WFV algorithm that includes a v

Where was ENSO strongest?

Science.gov (United States)

Cane, M. A.; Chen, D.; Kaplan, A.

2008-12-01

Mark A. Cane, Dake Chen, Alexey Kaplan The description of this session begins: "Historical SST records suggest that for the past three decades, ENSO has been anomalously strong" and goes on to ask why. In this talk we dispute this interpretation of the historical record from within the historical record. In particular, we suggest that the most "anomalously strong" period in the historical ENSO record is the late nineteenth century. This claim requires a discussion of how we measure "ENSO strength". We also speculate on possible reasons for the strength of ENSO in this earlier period. Finally, we consult the models, and in reiteration of the collective conclusion of all speakers at this session, find that the riddles the models provide are inelegant and disobliging, lacking the cryptic wisdom of the classical oracles.

The waste heat from two combined heat and power plants on the Ulmenhof farm near Mandern in the federal state of Rhineland-Palatinate used to simply escape into the air. Now farmer Ralf Backes uses it to heat water which he pipes to the neighboring ThyssenKrupp Bilstein plant. It's a textbook example of how waste heat can be utilized in industrial processes. The auto part business, which with over 800 employees produces shock absorbers and air suspension systems for various German and international automobile manufacturers, has now halved the energy costs of its paint shop.

Full Text Available The article presents an analysis of A. Butovsky's views on the physical education in Sweden, and, first of all, on the system of Swedish gymnastics. Alexey Butovsky got acquainted with it in 1892 while visiting that country on a mission trip, and later he generalized that system in some of his works. Positive and negative points of Swedish physical education, the role of the Royal Gymnastics Central Institute in Stockholm are examined, and some prominent figures of Sweden, who governed it at different periods, are characterized. Aspects of various exercises from this system are accentuated. It is marked that the Swedish gymnastics on the orientation, on principle differed composition of exercises and method of their application from other gymnastic systems in XIX century. It is underlined that exercises of the Swedish gymnastics differ naturalness of poses and motions, absence in them of maximal efforts, hard and rough motions.

Dabei wurden medienbezogene Wissensbestände von drei Alterskohorten globaler Generationen analysiert. Der Artikel diskutiert methodologische Aspekte des Projekts und komplexe und selektive Prozesse des Erinnerns vergangener Ereignisse. Er untersucht Gemeinsamkeiten und Unterschiede des GMG-Ansatzes mit dem dokumentarischen Ansatz von Ralf Bohnsack, die beide in der Wissenssoziologie von Karl Mannheim verwurzelt sind. Darüber hinaus wird Medialität als basale methodologische Kategorie in Erwägung gezogen, nicht nur im Hinblick auf die Klärung begrifflicher Grundlagen, sondern auch als inhärente Dimension von Forschungsprozessen.

Not just a facelift but a real change in the way that safety at CERN is supported by the Organization: the Safety Commission becomes the occupational Health & Safety and Environmental protection (HSE) Unit. The new name reflects a profound change in terms of vision, mission and, above all, effectiveness.   Safety is a broad term that incorporates many concepts and related issues. In the vision of the HSE Unit, safety is built on two pillars: occupational health & safety and environmental protection, both comprising conventional and radiological aspects. “Ensuring safety in these two areas is a matter of highest importance for the Organization”, says Ralf Trant, head of the HSE Unit. “Our vision focuses on improving our efficiency in serving the Organization in all matters of safety.

[Plant signaling peptides. Cysteine-rich peptides].

Science.gov (United States)

Ostrowski, Maciej; Kowalczyk, Stanisław

2015-01-01

Recent bioinformatic and genetic analyses of several model plant genomes have revealed the existence of a highly abundant group of signaling peptides that are defined as cysteine-rich peptides (CRPs). CRPs are usually in size between 50 and 90 amino acid residues, they are positively charged, and they contain 4-16 cysteine residues that are important for the correct conformational folding. Despite the structural differences among CRP classes, members from each class have striking similarities in their molecular properties and function. The present review presents the recent progress in research on signaling peptides from several families including: EPF/EPFL, SP11/SCR, PrsS, RALF, LURE, and some other peptides belonging to CRP group. There is convincing evidence indicating multiple roles for these CRPs as signaling molecules during the plant life cycle, ranging from stomata development and patterning, self-incompatibility, pollen tube growth and guidance, reproductive processes, and nodule formation.

Peroxisomes contain numerous enzymatic activities that are important for mammalian physiology. Patients lacking either all peroxisomal functions or a single enzyme or transporter function typically develop severe neurological deficits, which originate from aberrant development of the brain, demyelination and loss of axonal integrity, neuroinflammation or other neurodegenerative processes. Whilst correlating peroxisomal properties with a compilation of pathologies observed in human patients and mouse models lacking all or individual peroxisomal functions, we discuss the importance of peroxisomal metabolites and tissue- and cell type-specific contributions to the observed brain pathologies. This enables us to deconstruct the local and systemic contribution of individual metabolic pathways to specific brain functions. We also review the recently discovered variability of pathological symptoms in cases with unexpectedly mild presentation of peroxisome biogenesis disorders. Finally, we explore the emerging evidence linking peroxisomes to more common neurological disorders such as Alzheimer’s disease, autism and amyotrophic lateral sclerosis.

Radiation protection and radiation safety: CERN and its host states to sign a tripartite agreement.

CERN Multimedia

2010-01-01

On 15 November CERN and its Host States will sign a tripartite agreement that replaces the existing bilateral agreements in matters of radiation protection and radiation safety at CERN. It will provide, for the first time, a single forum where the three parties will discuss how maximum overall safety can best be achieved in the specific CERN context.   CERN has always maintained close collaboration with its Host States in matters of safety. “The aim of this collaboration is especially to ensure best practice in the field of radiation protection and the safe operation of CERN’s facilities”, explains Ralf Trant, Head of the Occupational Health & Safety and Environmental Protection (HSE) Unit. Until today, CERN’s collaboration with its Host States was carried out under two sets of bilateral agreements: depending on which side of the French-Swiss border they were being carried out on, a different framework applied to the same activities. This approach has b...

Role of CrRLK1L Cell Wall Sensors HERCULES1 and 2, THESEUS1, and FERONIA in Growth Adaptation Triggered by Heavy Metals and Trace Elements

Full Text Available Cell walls are not only a protective barrier surrounding protoplasts but serve as signaling platform between the extracellular environment and the intracellular physiology. Ions of heavy metals and trace elements, summarized to metal ions, bind to cell wall components, trigger their modification and provoke growth responses. To examine if metal ions trigger cell wall sensing receptor like kinases (RLKs of the Catharanthus roseus RLK1-like (CrRLK1L family we employed a molecular genetic approach. Quantitative transcription analyses show that HERCULES1 (HERK1, THESEUS1 (THE1, and FERONIA (FER were differently regulated by cadmium (Cd, nickel (Ni, and lead (Pb. Growth responses were quantified for roots and etiolated hypocotyls of related mutants and overexpressors on Cd, copper (Cu, Ni, Pb, and zinc (Zn and revealed a complex pattern of gene specific, overlapping and antagonistic responses. Root growth was often inversely affected to hypocotyl elongation. For example, both HERK genes seem to negatively regulate hypocotyl elongation upon Cd, Ni, Zn, and Pb while they support root growth on Cd, Cu, and Ni. The different THE1 alleles exhibited a similar effect between roots and hypocotyls on Ni, where the loss-of-function mutant was more tolerant while the gain of function mutants were hypersensitive indicating that THE1 is mediating Ni specific inhibition of hypocotyl elongation in the dark. In contrast hypocotyl elongation of the knock-out mutant, fer-4, was hypersensitive to Ni but exhibited a higher tolerance to Cd, Cu, Pb, and Zn. These data indicate an antagonistic action between THE1 and FER in relation to hypocotyl elongation upon excess of Ni. FERs function as receptor for rapid alkalinization factors (RALFs was tested with the indicator bromocresol purple. While fer-4 roots strongly acidified control and metal ion containing media, the etiolated hypocotyls alkalized the media which is consistent with the already shorter hypocotyl of fer-4

Full Text Available Alexey B Mantsyzov,1 Guillaume Bouvier,2 Nathalie Evrard-Todeschi,1 Gildas Bertho11Université Paris Descartes, Sorbonne, Paris, France; 2Institut Pasteur, Paris, FranceAbstract: Evaluation of docking results is one of the most important problems for virtual screening and in silico drug design. Modern approaches for the identification of active compounds in a large data set of docked molecules use energy scoring functions. One of the general and most significant limitations of these methods relates to inaccurate binding energy estimation, which results in false scoring of docked compounds. Automatic analysis of poses using self-organizing maps (AuPosSOM represents an alternative approach for the evaluation of docking results based on the clustering of compounds by the similarity of their contacts with the receptor. A scoring function was developed for the identification of the active compounds in the AuPosSOM clustered dataset. In addition, the AuPosSOM efficiency for the clustering of compounds and the identification of key contacts considered as important for its activity, were also improved. Benchmark tests for several targets revealed that together with the developed scoring function, AuPosSOM represents a good alternative to the energy-based scoring functions for the evaluation of docking results.Keywords: scoring, docking, virtual screening, CAR, AuPosSOM

Full Text Available The article deals with the failed attempt to organize and legalize the Leningrad’s diocesan administration of the Russian Orthodox Church in 1926. At the suggestion of OGPU the group of Leningrad’s clergy has propounded legalization. Bishop Alexius (Simanskiy became the leader of the group in the summer of 1926. The initiative group’s activity aroused suspicion of the part of the Leningrad clergy assuring a top church management to transfer bishop Alexey to another diocese and to appoint Joseph (Petrovyh to be a Leningrad metropolitan. The conflict situation was complicated by the provocative politics of a state authority. It prevented metropolitan Joseph from carrying out his duties of ruling archbishop and, on the contrary, permitted the initiative group to hold a meeting led by bishop (archbishop Alexius. All attempts of church workers to find the unconflicted way out were unsuccessful. The author analyses arguments of supporters and opponents of the diocesan legalization, estimates the correlation between personal and based on principles motives. He investigates the position of church authority represented by metropolitan Sergey (Stragorodskiy. The author considers either side was not unjust one in the Leningrad church collision in 1926. Only the politics of the soviet power that used legalization as the demoralization’s instrument of the Church was defi nitely malicious.

Discourse Analysis of the Documentary Method as "Key" to Self-Referential Communication Systems? Theoretic-Methodological Basics and Empirical Vignettes

Directory of Open Access Journals (Sweden)

Gian-Claudio Gentile

2010-09-01

Full Text Available Niklas LUHMANN is well known for his deliberate departure from the classical focus on studying individual actions and directing attention on the actors' relatedness through so called (autopoietic communication systems. In contrast to the gain of a new perspective of observation his focus on autopoietic systems is simultaneously its biggest methodological obstacle for the use in social and management sciences. The present contribution considers the above shift on a theoretical level and with a specific qualitative method. It argues for a deeper understanding of systemic sense making and its enactment in a systematic and comprehensible way. Central to this approach is its focus on groups. Using group discussions as the method of data collection, and the "documentary method" by Ralf BOHNSACK (2003 as a method of data analysis, the article describes a methodologically grounded way to record the self-referential systems proposed by LUHMANN's system theory. The theoretical considerations of the paper are illustrated by empirical vignettes derived from a research project conducted in Switzerland concerning the social responsibility of business.

ofsupport for the convent. The convent received money; several dozens new novices were admitted, and the situation changed considerably for the better. It seemed that the most diffi cult period was over. However, in 1959 the USSR authorities decided to close down all the monasteries. Archival materials show how thoroughly planned and carefully carried out those activities were.In 1961 a decision was made to close down the Pühtitsa Convent. It was at that time that Bishop Alexey (Ridiger, the future Patriarch Alexey II, was appointed head of the Estonian eparchy. The bishop had had experience of working for the Department of External Church Relations (DECR of the Moscow Patriarchate, and perhaps it was this experience, that suggested to him the way to save the convent. The bishop brought several foreign delegations to Pühtitsa, and some articles about the convent appeared in foreign press.In these circumstances, the authorities did not dare to close the convent. Subsequently, several sisters from the convent headed newly created convents all across Russia, passing them on the tradition of Orthodox monastic life

Full Text Available Amr A Faddan, Alexey V Aksenov, Carsten M Naumann, Klaus P Jünemann, Daniar K Osmonov Department of Urology and Pediatric Urology, University Hospital Schleswig-Holstein, Kiel, Germany Introduction: Priapism is the persistent erection resulting from dysfunction of the mechanisms that regulate penile swelling, stiffness, and sagging. It is a full or partial erection that persists for a period more than 4 hours beyond sexual stimulation and/or orgasm or is unrelated to sexual stimulation. Ischemic priapism should be managed in a step-by-step fashion. Objective: To demonstrate step-by-step management of stuttering refractory ischemic priapism. We report a case of stuttering refractory ischemic priapism. Moreover, we reviewed different approaches to priapism management in the literature. Case presentation: A 53-year-old male presented with a painful erection of 29 hours’ duration, probably caused by consumption of alcohol. The penile blood gas showed a pH of 7.08, PCO2 of 75 mmHg and PO2 of 39 mmHg. Aspiration was followed by irrigation of an α-adrenergic, Winter and T-shunt operations were preformed, and finally a semi-rigid penile prosthesis was implanted to overcome the refractory stuttering ischemic priapism. Conclusion: In case of stuttering refractory ischemic priapism, immediate implantation of a penile prosthesis is a simple and effective procedure that manages both the acute episode and the inevitable erectile dysfunction that would otherwise occur, while preserving penile length. Keywords: priapism, stuttering priapism, shunting operation, penile prosthesis

Germination response of Hylocereus setaceus (Salm-Dyck ex DC: ) Ralf Bauer (Cactaceae) seeds to temperature and reduced water potentials.

2010-02-01

The germination response of Hylocereus setaceus seeds to isothermic incubation at different water potentials was analysed by using the thermal time and hydrotime models, aiming to describe some germination parameters of the population and to test the validity of the models to describe the response of the seeds to temperature and water potential. Hylocereus setaceus seeds germinated relatively well in a wide range of temperatures and the germination was rate limited from 11 to 20 degrees C interval and beyond 30 degrees C until 40 degrees C, in which the germination rate respectively shifts positively and negatively with temperature. The minimum or base temperature (T(b)) for the germination of H. setaceus was 7 degrees C, and the ceiling temperature varied nearly from 43.5 to 59 degrees C depending on the percent fraction, with median set on 49.8 degrees C. The number of degrees day necessary for 50% of the seeds to germinate in the infra-optimum temperature range was 39.3 degrees C day, whereas at the supra-optimum interval the value of theta = 77 was assumed to be constant throughout. Germination was sensitive to decreasing values of psi in the medium, and both the germinability and the germination rate shift negatively with the reduction of psi, but the rate of reduction changed with temperature. The values of base water potential (psi(b)) shift to zero with increasing temperatures and such variation reflects in the relatively greater effect of low psi on germination in supra optimum range of T. In general, the model described better the germination time courses at lower than at higher water potentials. The analysis also suggest that Tb may not be independent of psi and that psi(b(g)) may change as a function of temperature at the infra-otimum temperature range.

The current legislative process for the site selection law (StandAG) was topic of the DAtF event 'Energy in a Dialog' on 6 June 2013 in Berlin: 'Is the path the goal: purpose and results of the site selection law'. The President of the German Atomic Forum (DAtF), Dr. Ralf Gldner, moderated the discussion with Prof. Dr. Ortwin Renn of the University of Stuttgart and the CEO of the Gesellschaft fuer Nuklear-Service (GNS), Hannes Wimmer. The opportunities and risks of a new site search for high-level radioactive waste were the main topics. Professor Renn summarized some findings to conditions of acceptance perceived in connection with industrial projects. Dr. Wimmer said in his keynote that social acceptance for site selection for a repository must be maintained for a long time. During the ensuing discussion, a common understanding was evident on some aspects of the topic. This is especially true for a limitation of the new location search method in terms of its objective. As a realistic objective to determine a secure suitable site was considered instead of a 'best' location proposed by the new law. (orig.)

Pharmacological and pharmacokinetic aspects are reviewed and the current clinical use of daptomycin is presented. Daptomycin seems to be a reliable drug in the treatment of complicated skin and skin structure infections, infective right-sided endocarditis, and bacteremia caused by Gram-positive agents. Its unique mechanism of action and its low resistance profile, together with its rapid bactericidal action make it a favorable alternative to vancomycin in multi-drug resistant cocci. The role of daptomycin in the treatment of prosthetic material infections, osteomyelitis, and urogenital infections needs to be evaluated in randomized clinical trials.Keywords: daptomycin, multi-drug resistance, methicillin-resistant Staphylococcus aureus (MRSA, pneumonia, urinary tract infection, left-sided endocarditis

Many of these signatures were reviewed in the 5 rapporteur talks covering high-pT and jets (Kirill Filimonov, LBNL), bulk properties and collective flow (Zhangbu Xu, BNL), correlations and HBT (Harald Appelhauser, GSI), leptons, photons and heavy quarks (Ralf Averbeck, Stony Brook) and theory (Ralf Rapp, Texas A and M). In addition, Mike Lisa (Ohio State), Miklos Gyulassy (Colombia) and Peter Braun-Munzinger (GSI) gave their personal views on the QGP

We present the findings from four recently published studies conducted in Russia assessing Hylabak® (marketed as Hyabak® in Europe, a preservative-free hyaluronic acid preparation, for the treatment of dry eye syndrome. All studies had an open, noncomparative design, but one compared the findings with those from 25 patients treated with Tear Naturale® in previous studies. A total of 134 children and adults were enrolled, and the etiologies of dry eye syndrome included contact lens use, intensive office work, adenovirus eye infection, postmenopausal status, persistent meibomian blepharitis, Sjögren's syndrome, phacoemulsification with intraocular lens implantation, and refractive surgery. The patients were treated with Hylabak for 2 weeks to 2 months. All studies showed that Hylabak resulted in marked improvement as assessed by subjective sensations/complaints, Schirmer's test, Norn’s test, impression cytology and biomicroscopy, staining, and tear osmolarity. Greater benefits were also reported compared with Tear Naturale, including a faster onset of action. Hylabak was well tolerated. In conclusion, Hylabak provided rapid and safe relief from the signs and symptoms of dry eye syndrome, as well as improvement in objective measures, in a wide range of patients.Keywords: dry eye, eye drops, artificial tears, hyaluronic acid, Hylabak®, preservative-free

earthquake. However, today it is not yet possible. Ground-based sea radars. This is an effective tool for direct measurement of tsunami wave. At the same time, the wave is measured at a rather narrow area in front of the radar and does not include information about neighboring parts of the wave. Direct measurement of tsunami wave at deep water [2]. Today, this technology is certainly among the most useful and promising. The DART II® system consists of a seafloor bottom pressure recording (BPR) system, capable of detecting tsunamis as small as 1 cm, and a moored surface buoy for real-time communications. We focus our research on improving the later method, direct measurement of tsunami wave at deep water. We suggest the new way to analyze DART data, modifying the methodology originally proposed by V. Titov. Smaller system of unit sources [3] should be considered to approximate all typical shapes of initial disturbance by several suitable basis functions. To successfully implement it, performance of data analysis should be dramatically improved. This could be done by using a signal orthogonalization procedure for considered system of unit sources and calculation of Fourier coefficients of the measured time series with respect to orthogonal basis. The approach suggested was used as a part of computerized workstation for tsunami hazard monitoring [5-6]. National Oceanic and Atmospheric Administration Center for Tsunami Research.

The challenges posed by the energy turnaround in Germany to the power industry and the national economy after the Fukushima events were the topic of the ''Energy in a Dialog'' meeting organized by the Deutsches Atomforum in Berlin on December 14, 2011. Dr. Ralf Gueldner, President of the Deutsches Atomforum, opened the conference by drawing attention to the real purposes of the energy turnaround, namely to prevent severe climate changes and, thus, also carbon emissions. Both nationally in Germany and worldwide, nuclear power made major contributions to achieving these goals. Referring to developments in many neighboring countries, he underlined that opting out of the use of nuclear power in Germany was not tantamount to the end of nuclear power. Reality in energy policy had to be accepted, however, namely that nuclear power played, and would go on playing, an important role in Europe. Other contributions by Dr. Juergen Grossmann (Chief Executive Officer of RWE AG), Stefan Kohler (Chairman of the Board of Management of the German Energy Agency - dena), and Prof.Dr. Felix Muesgens (Brandenburg Technical University of Cottbus, Chair of Power Economics) dealt with political and other boundary conditions required for the energy turnaround, and with the consequences and burdens on the power industry and the national economy. A final panel discussion chaired by Henning Krumrey (Wirtschaftswoche) was attended by F. Muesgens and Prof. Dr. Hans-Werner Sinn (President of the Munich-based Info Institute) and Prof. Dr. Michael Huether (German Business Institute). (orig.)

Lung function parameters and comorbidities of the patient, as well as the extent and distribution of the emphysema are factors to be considered when choosing the patient and the intervention. Endoscopic bronchial valve placement with complete occlusion of one lobe in patients with heterogeneous emphysema is the preferred technique because of its reversibility. The presence of high interlobar collateral ventilation will hinder successful treatment; therefore, endoscopic coil placement, polymeric lung volume reduction, or bronchoscopic thermal vapor ablation as well as lung volume reduction surgery can be used for treating patients with incomplete fissures. The effect of endoscopic lung volume reduction in patients with a homogeneous distribution of emphysema is still unclear and this subgroup should be treated only in clinical trials. Precise patient selection is necessary for interventions and to improve the outcome and reduce the risk and possible complications. Therefore, the patients should be discussed in a multidisciplinary approach prior to determining the most appropriate treatment for lung volume reduction.

Troughs on Martian Ice Sheets: Analysis of Their Closure and Mass Balance

At the Copenhagen workshop on Martian polar processes, Ralf Greve commented that the flow regime surrounding scarps and troughs of the Martian polar ice sheets cannot be modeled using traditional "plan view" ice-sheet models. Such models are inadequate because they typically use reduced equations that embody certain simplifications applicable only to terrestrial ice sheets where the upper ice sheet surface is smooth. In response to this suggestion, we have constructed a 2-dimensional, time dependent "side view" (two spatial dimensions: one horizontal, one vertical) model of scarp closure that is designed to overcome the difficulties described by Greve. The purpose of the model is to evaluate the scales of stress variation and styles of flow closure so as to estimate errors that may be encountered by "plan view" models. We show that there may be avenues whereby the complications associated with scarp closure can be overcome in "plan view" models through appropriate parameterizations of 3-dimensional effects. Following this, we apply the flow model to simulate the evolution of a typical scarp on the North Polar Cap of Mars. Our simulations investigate: (a) the role of "radiation trapping" (see our companion abstract) in creating and maintaining "spiral-like" scarps on the ice sheet, (b) the consequences of different flowlaws and ice compositions on scarp evolution and, in particular, scarp age, and (c) the role of dust and debris in scarp evolution.

On June 29, 2006, the Radiochemical Laboratory of AREVA NP GmbH (formerly Siemens AG) in Erlangen celebrated its fiftieth anniversary. The occasion was marked by an event attended by more than 1,000 guests, among them Werner Gebauhr, the 85-year-old founder and first head of the Laboratory; the Managing Directors of AREVA NP GmbH, Ralf Gueldner and Ruediger Steuerlein; representatives of universities, research institutions, power utilities, and public authorities. The present head of the Radiochemical Laboratory, Wilfred Morell, sketched the highlights of the work performed over the past fifty years, which ranged from solid-state and very-high-purity materials technologies to development and service activities for nuclear technology. Manfred Erve, head of the Technical Center of AREVA NP GmbH, of which the Radiochemical Laboratory is a part, emphasized the changes in priorities over the past fifty years, which had always been met successfully by Radiochemistry. In the scientific part of the event, Wolfgang Schwarz (E.ON Kernkraftwerk GmbH, KKW Isar), Ulf Ilg (EnBW Kraftwerk AG, KKW Philippsburg), and Hans-Josef Allelein (Gesellschaft fuer Anlagen- und Reaktorsicherheit mbH) explained 3 major subject areas in which Erlangen Radio-chemistry over many years has contributed basic findings (see other articles in this atw issue). On the occasion of the anniversary, a comprehensive booklet was published under the title of '50 Jahre Radiochemie Erlangen - 1956-2006'. (orig.)

Prediction of molecular mimicry candidates in human pathogenic bacteria.

Doxey, Andrew C; McConkey, Brendan J

2013-08-15

Molecular mimicry of host proteins is a common strategy adopted by bacterial pathogens to interfere with and exploit host processes. Despite the availability of pathogen genomes, few studies have attempted to predict virulence-associated mimicry relationships directly from genomic sequences. Here, we analyzed the proteomes of 62 pathogenic and 66 non-pathogenic bacterial species, and screened for the top pathogen-specific or pathogen-enriched sequence similarities to human proteins. The screen identified approximately 100 potential mimicry relationships including well-characterized examples among the top-scoring hits (e.g., RalF, internalin, yopH, and others), with about 1/3 of predicted relationships supported by existing literature. Examination of homology to virulence factors, statistically enriched functions, and comparison with literature indicated that the detected mimics target key host structures (e.g., extracellular matrix, ECM) and pathways (e.g., cell adhesion, lipid metabolism, and immune signaling). The top-scoring and most widespread mimicry pattern detected among pathogens consisted of elevated sequence similarities to ECM proteins including collagens and leucine-rich repeat proteins. Unexpectedly, analysis of the pathogen counterparts of these proteins revealed that they have evolved independently in different species of bacterial pathogens from separate repeat amplifications. Thus, our analysis provides evidence for two classes of mimics: complex proteins such as enzymes that have been acquired by eukaryote-to-pathogen horizontal transfer, and simpler repeat proteins that have independently evolved to mimic the host ECM. Ultimately, computational detection of pathogen-specific and pathogen-enriched similarities to host proteins provides insights into potentially novel mimicry-mediated virulence mechanisms of pathogenic bacteria.

Its mechanism of action may comprise immunomodulatory effects on T-cells, monocytes, and dendritic cells as well as neuroprotective effects with prominent actions on astrocytes. Laquinimod was tested in Phase II and III clinical trials in RRMS at different dosages ranging from 0.1 to 0.6 mg/day. The compound was well tolerated, yet at the dosages tested only led to moderate effects on the reduction of relapse rates as primary study endpoint in Phase III trials. In contrast, significant effects on brain atrophy and disease progression were observed. While there were no significant safety signals in the clinical trials, the Committee for Medicinal Products for Human Use (CHMP refused marketing authorization for RRMS based on the assessment of the risk–benefit ratio with regard to data from animal studies. At present, the compound is further tested in RRMS as well as CPMS and Huntington’s disease at different concentrations. Results from these trials will further inform about the clinical benefit of laquinimod in patient cohorts with a persisting, but still insufficiently met need for safe and at the same time effective oral compounds with neuroprotective effects.Keywords: neuroprotection, ABR-215062, axonal damage, demyelination

Stratospheric chlorine: Blaming it on nature

International Nuclear Information System (INIS)

Taube, G.

1993-01-01

Much of the bitter public debate over ozone depletion has centered on the claim that chlorofluorocarbons (CFCs) pale into insignificance alongside natural sources of chlorine in the stratosphere. If so, goes the argument, chlorine could not be depleting ozone as atmospheric scientists claim, because the natural sources have been around since time immemorial, and the ozone layer is still there. The claim, put forward in a book by Rogelio Maduro and Ralf Schauerhammer, has since been touted by former Atomic Energy Commissioner Dixy Lee Ray and talk-show host Rush Limbaugh, and it forms the basis of much of the backlash now being felt by atmospheric scientists. The argument is simple: Maduro and Schauerhammer calculate that 600 million tons of chlorine enters the atmosphere annually from seawater, 36 million tons from volcanoes, 8.4 million tons from biomass burning, and 5 million tons from ocean biota. In contrast, CFCs account for a mere 750,000 tons of atmospheric chlorine a year. Besides disputing the numbers, scientists have both theoretical and observational bases for doubting that much of this chlorine is getting into the stratosphere, where it could affect the ozone layer. Linwood Callis of the National Aeronautics and Space Administration's (NASA) Langley Research Center points out one crucial problem with the argument: Chlorine from natural sources is soluble, and so it gets rained out of the lower atmosphere. CFCs, in contrast, are insoluble and inert and thus make it to the stratosphere to release their chlorine. What's more, observations of stratospheric chemistry don't support the idea that natural sources are contributing much to the chlorine there

Full Text Available AIM: This study aimed to evaluate the influence of river-dam axis and abiotic factors on the composition of Closteriaceae, Gonatozygaceae, Mesotaeniaceae and Peniaceae in a tropical reservoir METHODS: Water samples for physical, chemical and periphyton analysis were collected in April and August 2002 in different regions along the axis of the river-dam of Rosana Reservoir, River Basin Paranapanema. The substrates collected, always in the litoranea region, were petioles of Eichhornia azurea (Swartz Kunth. To examine the relationship of abiotic variables with reservoir zones and between the floristic composition of desmids, we used principal component analysis (PCA and canonical correspondence analysis (CCA RESULTS: The results of the PCA explained 81.3% of the total variability in the first two axes. In the first axis, the variables of conductivity, water temperature and the pH were related to the sampling regions of April with higher values, while for the month of August, nitrate, total phosphorus and dissolved oxygen showed higher values. We identified 20 taxa, distributed in the genera Closterium (14, Gonatozygon (4, Netrium (1 and Penium (1. Spatially, the higher taxa were recorded in the lacustrine region for both collection periods. The canonical correspondence analysis (CCA summarized 62.2% of total data variability of taxa in the first two axes, and in August, Closterium incurvum Brébisson, C. cornu Ehrenberg ex Ralfs and Gonatozygon monotaenium De Bary, were related to higher values of turbidity and nitrate to the lacustrine and intermediate regions CONCLUSION: Thus, the formation of groups was due to the regions along the longitudinal axis, then the seasonal period, which must be related to the low current velocity, the higher values of temperature and the water transparency, especially in late summer

Our objective was to analyze wound healing and to assess potential factors affecting the healing process.Methods: 199 patients were included in this 5-year study. The significance levels were determined by chi-squared and log-rank tests. The calculation of patency rate followed the Kaplan-Meier method.Results: Mean age and co-morbidities did not differ from those in current epidemiological studies. Of the patients with ulcer latency of more than 13 weeks (up to one year, 40% required vascular surgery. Vascular surgery was not possible for 53 patients and they were treated conservatively. The amputation rate in the conservatively treated group was 37%, whereas in the revascularizated group it was only 16%. Ulcers in patients with revascularization healed in 92% of cases after 24 weeks. In contrast, we found a healing rate of only 40% in the conservatively treated group (p < 0.001. Revascularization appeared more often in diabetic patients (n = 110; p < 0.01 and the wound size and number of infections were elevated (p = 0.03. Among those treated conservatively, wound healing was decelerated (p = 0.01/0.02; χ² test.Conclusions: The success of revascularization, presence of diabetes mellitus, and wound treatment proved to be prognostic factors for wound healing in arterial ulcers.Keywords: arterial leg ulcer, wound management, risk factors, revascularization

The Second International Conference and Young Scientist School ''Magnetic resonance imaging in biomedical research'' was held on the campus of the National Research Tomsk State University (Tomsk, Russia) on September 7-9, 2015. The conference was focused on magnetic resonance imaging (MRI) applications for biomedical research. The main goal was to bring together basic scientists, clinical researchers and developers of new MRI techniques to bridge the gap between clinical/research needs and advanced technological solutions. The conference fostered research and development in basic and clinical MR science and its application to health care. It also had an educational purpose to promote understanding of cutting-edge MR developments. The conference provided an opportunity for researchers and clinicians to present their recent theoretical developments, practical applications, and to discuss unsolved problems. The program of the conference was divided into three main topics. First day of the conference was devoted to educational lectures on the fundamentals of MRI physics and image acquisition/reconstruction techniques, including recent developments in quantitative MRI. The second day was focused on developments and applications of new contrast agents. Multinuclear and spectroscopic acquisitions as well as functional MRI were presented during the third day of the conference. We would like to highlight the main developments presented at the conference and introduce the prominent speakers. The keynote speaker of the conference Dr. Vasily Yarnykh (University of Washington, Seattle, USA) presented a recently developed MRI method, macromolecular proton fraction (MPF) mapping, as a unique tool for modifying image contrast and a unique tool for quantification of the myelin content in neural tissues. Professor Yury Pirogov (Lomonosov Moscow State University) described development of new fluorocarbon compounds and applications for biomedicine. Drs. Julia Velikina and Alexey

Tying it all together: telomeres, sexual size dimorphism and the gender gap in life expectancy.

The classic explanation that women outlive men solely due to hormonal and lifestyle differences, does not withstand a critical analysis. In developed countries, the average gap in life expectancy between the sexes is 7 years. It has widened over the last decades, despite the trend of women copying the 'unhealthy' lifestyle of men. Estrogen levels in postmenopausal women are virtually identical to estrogen levels in males and can hardly explain the discrepancy. Furthermore, testosterone got its bad reputation from one study on mentally retarded men, which has to be interpreted with caution. However, sexual size dimorphism with men being the larger sex in conjunction with the limited replication potential of human somatic cells might account for higher mortality rates in males, especially at old age. The hypothesis, as presented here, is based on the well-known concept of a cellular mitotic clock, which was discovered by Leonard Hayflick almost half a century ago. The underlying counting mechanism, namely the gradual erosion of chromosome ends (telomeres) due to the end replication problem of linear DNA molecules, was first described by Alexey Olovnikov in 1971 and with minor modifications has become a widely accepted paradigm. In a recent Lancet study, an inverse correlation between mean telomere length and mortality in people has been found. In this and two other studies, it was confirmed that males do have shorter telomeres than females at the same age. This is almost certainly a consequence of men being usually taller than women, although nobody has done an investigation yet. Clearly, a larger body requires more cell doublings, especially due to the ongoing regeneration of tissues over a lifetime. Accordingly, the replicative history of male cells might be longer than that of female cells, resulting in the exhaustion of the regeneration potential and the early onset of age-associated diseases predominantly in large-bodied males. Inherited telomere length

Full Text Available Plants as C3 and CAM react photosynthetically different but both can grow in the same agroecological zone in the tropics. Therefore we studied the behavior of stomatal opening in fruits and leaves of the purple passion fruit and fruits and cladodes of the yellow pitaya was studied under natural growing conditions in Granada and Fusagasuga, Cundinamarca (Colombia. Imprints were made on the surface of leaves, fruits and cladodes using cosmetic enamel impressions. Three cycles were carried out, each cycle took 72 hours, obtaining three different samples every 3 hours; then the impressions were observed by microscope and the opened and closed stomata were counted in each species. In each sampling, data of solar radiation, temperature and relative humidity (RH were measured. The purple passion fruit had the typical behavior of a C3 plant in the leaves as well as the fruits, and a positive correlation between the stomatal aperture and radiation and temperature was found, along with a negative correlation between stomatal aperture and RH. The pitaya showed the typical behavior of a CAM plant with a negative correlation between the stomatal opening and radiation and temperature, as well as a positive correlation between stomatal opening and RH. Radiation, temperature and RH affected the stomatal opening in the fruits and cladodes. Stomatal densities differed greatly between the species and plant organs. In the purple passion fruit, 106.53 stomata per mm² leaf surface were found, but only 12.64 stomata per mm² fruit surface; whereas in the pitaya, 11.28 and 1.43 stomata per mm² were found on the cladodes and fruits, respectively

Jörn Rossa (often spelled Joern Rossa) passed away on September 19, 2009 at the young age of 40 in Mainz, Germany from a virulent fast-acting blood cancer. He was born in that same city on March 17, 1969 to Alfred and Gudrun Rossa, who survive their only child. Joern had a deep, lifelong love of astronomy, as evidenced by the handwritten letters he wrote in his youth to prominent astronomers and astronauts for their perspectives, signatures and reprints, the popular astronomy magazines which he collected for decades, the decision to abandon a career as a locomotive driver and relearn the math and physics required to pursue his passion, the many papers he published himself, and the numerous space shuttle launches he made a point to personally attend at Kennedy Space Center. Since High School, Joern carried out observations using his own telescope, traveled with friends to remote locations to practice "serious" astrophotography, and lectured at a local amateur club. After attaining his undergraduate degree at the University of Heidelberg (Germany) in 1996, Joern continued his education at the Ruhr-University Bochum in Germany, where he worked under the guidance of Ralf-Juergen Dettmar. He received his Ph.D. degree in 2001 with a thesis focusing on extraplanar diffuse ionized gas and dust in the halos of edge-on spiral galaxies. He performed the largest-to-this-day ground-based H-alpha survey of a large number of galaxies, quantified their extraplanar ISM, and correlated its properties with the starburst activity in the galaxy disk. After his graduation, Joern stayed in Bochum for another year as a Postdoctoral Associate. During this time he expanded his interests in the same general subject area through the use of X-ray (XMM, Chandra) and radio observations. His interest in the ISM of nearby galaxies continued through his subsequent postdoctoral career. He analyzed high-spatial resolution Hubble Space Telescope (HST) WFPC2 H-alpha data of the edge-on non

The concept of society’s organic unity and its representation in the historiosophy of Vladimir Soloviev and the early Slavophiles

Full Text Available The meaning of the concept of society’s organic unity has been investigated. This concept was an important part of Russian religious philosophy in the middle of the XIX century. It has been found that Schelling and Hegel idealistic philosophy and orthodox theology were the main sources of the concept of organic unity. The character and forms of the presentation of the organic unity’s concept in Vladimir Soloviev and the main representatives of early Slavophilism’s social philosophy and philosophy of history has been analyzed. By Solovyov, the subject of the historical development is mankind as holistic, organic phenomenon which tries to overcome the formal unity and to reach its spiritual level in the form of «God-manhood». Economic and legal unity is called the lowest form of unity by Solovyov, and the highest one, which reaches the organic and conscious level, is the spiritual unity. In the philosophy of Ivan Kireyevski, society’s organic unity is opposed to the formal, rational unity. The formal unity was inherited by Europe from ancient Rome. Cultural traditions of Greece and Orthodoxy were inherited by Slavs and saved the spiritual unity of society. According to Alexey Khomyakov, there are two contrasting models of culture: Iranian and Cushitic ones. Iranian model is based on freedom and conscious action. Iranian model creates a spiritual unity without suppression of individuals in society. Cushitic model creates a formal unity, it coercions and suppress individuals. The formality of the state association and the spiritual unity of the community have been opposed by Konstantin Aksakov. In tsarist Russia, all power was given to the monarch to protect the community. Therefore, Russia maintained an organic, internal unity of the people unlike Europe. In Europe, the state became stronger then the communities and state there suppressed communities. Rights and economy became to be more important than morality. European society became

However, the lack of tactile feedback is an essential limiting factor for the further expansion. In robotic surgery, feedback related to touch is currently kinesthetic, and it is mainly aimed at the minimization of force applied to tissues and organs. Design and implementation of diagnostic tactile feedback is still an open problem. We hypothesized that a sufficient tactile feedback in robot-assisted surgery can be provided by utilization of Medical Tactile Endosurgical Complex (MTEC, which is a novel specialized tool that is already commercially available in the Russian Federation. MTEC allows registration of tactile images by a mechanoreceptor, real-time visualization of these images, and reproduction of images via a tactile display. Materials and methods: Nine elective surgeries were performed with da Vinci™ robotic system. An assistant performed tactile examination through an additional port under the guidance of a surgeon during revision of tissues. The operating surgeon sensed registered tactile data using a tactile display, and the assistant inspected the visualization of tactile data. First, surgeries where lesion boundaries were visually detectable were performed. The goal was to promote cooperation between the surgeon and the assistant and to train them in perception of the tactile feedback. Then, instrumental tactile diagnostics was utilized in case of visually undetectable boundaries. Results: In robot-assisted surgeries where lesion

Nitrous oxide is formed during nitrification and denitrification of ammonia that enters the soil during microbial decomposition of complex organic compounds. Denitrification can be direct and indirect. In the microbiological process of recovery of nitrates involved of the organic substance. In aerobic conditions microorganisms denitrificator behave like normal saprotrophs and oxidize organic matter in the act of breathing oxygen. Thus, they operate at different times two enzyme systems: the electron transport chain with an oxygen acceptor in aerobic and restoration of nitrates under anaerobic conditions. Investigation of the emission of nitrous oxide by ordinary Chernozem steppe of the Central-Chernozem Region showed that it depends on the type of cenosis and the content of available forms of nitrogen. Natural ecosystems emit nitrous oxide more than the soil of arable land. The dependence of the emission of nitrous oxide from the humus content shows positive trend, but the aggregation of data, significant differences are not detected. Research shows that nitrous oxide emissions are seasonal. So the autumn season is characterized by nitrous oxide emissions than spring. Enzymatic processes are an important link in the biological cycle of elements and, consequently, participate in the process of decomposition of organic matter, nitrification and other processes. Analysis of the data on enzyme activity of ordinary Chernozem and the intensity of emission of N20 shows a clear relationship between

Lutropin alpha, recombinant human luteinizing hormone, for the stimulation of follicular development in profoundly LH-deficient hypogonadotropic hypogonadal women: a review

The main cause can be traced back to an irregular or absent hypothalamic GnRH secretion, whereas only a minority suffers from a pituitary disorder. The choice of treatment to reverse this situation is a pulsatile GnRH application or a direct ovarian stimulation using gonadotropin injections. The goal is to achieve a proper ovarian function in these cases for a short time to allow ovulation and chance of pregnancy. Since the pulsatile GnRH treatment lost its former importance, several gonadotropins are in use to stimulate follicular growth, such as urine-derived human menopausal gonadotropin, highly purified follicle stimulating hormone (FSH or recombinant FSH, all with different success. The introduction of recombinant luteinizing hormone (LH and FSH provided an opportunity to investigate the distinct influences of LH and FSH alone and in combination on follicular growth in monofollicular ovulation induction cycles, and additionally on oocyte maturation, fertilization competence of the oocyte and embryo quality in downregulated IVF patients. Whereas FSH was known to be indispensable for normal follicular growth, the role of LH remained questionable. Downregulated IVF patients with this short-term gonadotropin depletion displayed no advance in stimulation success with the use of recombinant LH. Patients with hypogonadotropic hypogonadism undergoing monofollicular stimulation for ovulation induction showed clearly a specific role and need for both hormones in normal follicular growth.

In April 2006, a domestic building consisting of eleven prefabricated steel modules and designed by architect Ralf Kappes was constructed at Santa Monica, California, within just eight hours. The two-storey building has a living area of 230 square metres. Rooms are open, with versetzte Ebenen.. The climate of the Los Angeles region is warm, with a constant sea breeze. The building is designed for natural ventilation, and no air conditioning system is required. If it gets too hot, warm air will be withdrawn by a blower in the upper Treppenhaus. In the winter season, the sun shines right into the interior of the building, where solar heat is stored and then slowly released by the concrete floor. A PV system on the roof generates 75 percent of the electric power required, and there is also a solar thermal power system for water heating. The building was awarded the LEED Platinum Award (Leadership in Energy and Environmental Design). (orig.) [German] Im April 2006 verfolgten zahlreiche Schaulustige, wie aus elf vorfabrizierten Stahlmodulen innerhalb von acht Stunden ein Wohnhaus entstand.

Major differences in the transcriptional program underlying the phenotypic switch between exponential and post-exponential growth of Legionella pneumophila were formerly described characterizing important alterations in infection capacity. Additionally, a third state is known where the bacteria transform in a viable but nonculturable state under stress, such as starvation. We here describe phase-related proteomic changes in exponential phase (E), postexponential phase (PE) bacteria, and unculturable microcosms (UNC) containing viable but nonculturable state cells, and identify phase-specific proteins. We present data on different bacterial subproteomes of E and PE, such as soluble whole cell proteins, outer membrane-associated proteins, and extracellular proteins. In total, 1368 different proteins were identified, 922 were quantified and 397 showed differential abundance in E/PE. The quantified subproteomes of soluble whole cell proteins, outer membrane-associated proteins, and extracellular proteins; 841, 55, and 77 proteins, respectively, were visualized in Voronoi treemaps. 95 proteins were quantified exclusively in E, such as cell division proteins MreC, FtsN, FtsA, and ZipA; 33 exclusively in PE, such as motility-related proteins of flagellum biogenesis FlgE, FlgK, and FliA; and 9 exclusively in unculturable microcosms soluble whole cell proteins, such as hypothetical, as well as transport/binding-, and metabolism-related proteins. A high frequency of differentially abundant or phase-exclusive proteins was observed among the 91 quantified effectors of the major virulence-associated protein secretion system Dot/Icm (> 60%). 24 were E-exclusive, such as LepA/B, YlfA, MavG, Lpg2271, and 13 were PE-exclusive, such as RalF, VipD, Lem10. The growth phase-related specific abundance of a subset of Dot/Icm virulence effectors was confirmed by means of Western blotting. We therefore conclude that many effectors are predominantly abundant at either E or PE which suggests

Angular measurement technology at high resolution for applications such as in hard disk drive manufacturing machines, precision measurement equipment and aspherical process machines requires a rotary encoder with high accuracy, high resolution and high response speed. However, a rotary encoder has angular deviation factors during operation due to scale error or installation error. It has been assumed to be impossible to achieve accuracy below 0.1″ in angular measurement or control after the installation onto the rotating axis. Self-calibration (Lu and Trumper 2007 CIRP Ann. 56 499; Kim et al 2011 Proc. MacroScale; Probst 2008 Meas. Sci. Technol. 19 015101; Probst et al Meas. Sci. Technol. 9 1059; Tadashi and Makoto 1993 J. Robot. Mechatronics 5 448; Ralf et al 2006 Meas. Sci. Technol. 17 2811) and cross-calibration (Probst et al 1998 Meas. Sci. Technol. 9 1059; Just et al 2009 Precis. Eng. 33 530; Burnashev 2013 Quantum Electron. 43 130) technologies for a rotary encoder have been actively discussed on the basis of the principle of circular closure. This discussion prompted the development of rotary tables which achieve reliable and high accuracy angular verification. We apply these technologies for the development of a rotary encoder not only to meet the requirement of super-high accuracy but also to meet that of super-high resolution. This paper presents the development of an encoder with 221 = 2097 152 resolutions per rotation (360°), that is, corresponding to a 0.62″ signal period, achieved by the combination of a laser rotary encoder supplied by Magnescale Co., Ltd and a self-calibratable encoder (SelfA) supplied by The National Institute of Advanced Industrial Science & Technology (AIST). In addition, this paper introduces the development of a rotary encoder to guarantee ±0.03″ accuracy at any point of the interpolated signal, with respect to the encoder at the minimum resolution of 233, that is, corresponding to a 0.0015″ signal period after

The accumulation of hepatic TG and development of hepatic steatosis (HS) is a serious complication of the use of parenteral nutrition (PN) formulas containing a high percentage of dextrose. But whether fat emulsions or other nutrients can ameliorate the induction of HS by high-carbohydrate diets is still uncertain. We hypothesized that administration of a lipid emulsion (LE; Intralipid) and/or the vitamin A metabolite retinal (RAL) will reduce hepatic TG accumulation and attenuate indicators of inflammation. C57BL/6 male mice were fed PN formula as their only source of hydration and nutrition for 4–5 wk. In Expt. 1, mice were fed PN only or PN plus treatment with RAL (1 μg/g orally), LE (200 μL i.v.), or both LE and RAL. In Expt. 2, LE was orally administered at 4 and 13.5% of energy to PN-fed mice. All PN mice developed HS compared with mice fed normal chow (NC) and HS was reduced by LE. The liver TG mass was lower in the PN+LE and PN+RAL+LE groups compared with the PN and PN+RAL groups (P < 0.01) and in the 4% and 13.5% PN+LE groups compared with PN alone. Hepatic total retinol was higher in the RAL-fed mice (P < 0.0001), but RAL did not alter TG mass. mRNA transcripts for fatty acid synthase (Fasn) and sterol regulatory element-binding protein-1c (Srebpf1) were higher in the PN compared with the NC mice, but FAS protein and Srebpf1 mRNA were lower in the PN+LE groups compared with PN alone. The inflammation marker serum amyloid P component was also reduced. In summary, LE given either i.v. or orally may be sufficient to reduce the steatotic potential of orally fed high-dextrose formulas and may suppress the early development of HS during PN therapy.

A fourth hypothesis, involving recent horizontal gene transfer (HGT between A. obtectus and A. obvelatus, and from one of these species to Z. subfasciatus in the Mexican Altiplano, seems the only plausible explanation. The HGT between our study species seems to have occurred recently, and only in a zone where the three beetles are sympatric and share common host plants. This suggests that transfer could have been effected by some external vector such as a eukaryotic or viral parasite, which might still host the transferred fragment.

The neuroprotective and neurotherapeutic activity of recombinant Hsp70 was explored in a model of experimental stroke in rats. Ischemia was produced by the occlusion of the middle cerebral artery for 45 minutes. To assess its neuroprotective capacity, Hsp70, at various concentrations, was intravenously injected 20 minutes prior to ischemia. Forty-eight hours after ischemia, rats were sacrificed and brain tissue sections were stained with 2% triphenyl tetrazolium chloride. Preliminary treatment with Hsp70 significantly reduced the ischemic zone (optimal response at 2.5 mg/kg. To assess Hsp70’s neurotherapeutic activity, we intravenously administered Hsp70 via the tail vein 2 hours after reperfusion (2 hours and 45 minutes after ischemia. Rats were then kept alive for 72 hours. The

Full Text Available O presente trabalho tem como objetivo determinar a prevalência e a viabilidade de ovos e larvas de helmintos e cistos de protozoários presentes em biossólido e em esgoto submetido ao tratamento anaeróbio em estações de tratamento de esgoto onde são empregados reatores anaeróbios de lodo fluidizado (RALF, na região metropolitana de Curitiba, Paraná. Os parasitos presentes no esgoto e no lodo foram helmintos: Ascaris sp (85%, Toxocara sp (5,5%, Trichuris sp (4,5%, Hymenolepis diminuta (3,7%, H. nana (1% e Taenia sp (0,4%, Protozoários: Isospora sp, Entamoeba coli, Entamoeba histolytica, Giardia lamblia, Endolimax nana. Houve diferença significativa quanto ao número de ovos viáveis de helmintos presentes no material de quatro estações estudadas. A redução da viabilidade dos ovos de helmintos variou de 59,7 a 93%. No tratamento biológico baseado na digestão anaeróbia a eficácia depende do tempo e da temperatura. Novos tratamentos higienizantes são necessários para a utilização do lodo produzido por digestão anaeróbia na reciclagem em agricultura ou para outros objetivos visando reduzir o risco para saúde humana e animal.This study evaluates the prevalence and viability of helminth eggs and protozoan cysts in sludge obtained by anaerobic treatment in four treatment stations in Curitiba, Parana State, Brazil. The parasites observed were helminths: Ascaris sp (85%, Toxocara sp (5.5%, Trichuris sp (4.5%, Hymenolepis diminuta (3.7%, H. nana (1% and Taenia sp (0.4%, protozoan: Isospora sp, Entamoeba coli, Entamoeba histolytica, Giardia lamblia, Endolimax nana. In biological treatment based on the anaerobic digestion the effectiveness depends on the duration and temperature. The treatment showed efficiency for pathogen reduction of between 59.7 to 93%. However, the number of helminth eggs found in treatment stations was still high and new higher performance treatment is necessary for land application or for other objectives

However, despite its benefits, the outcome of ELVR remains difficult to predict. We investigated whether clinical success could be predicted by emphysema distribution assessed by computed tomography scan and baseline perfusion assessed by perfusion scintigraphy. Data from 57 patients with no CV in the target lobe (TL were retrospectively analyzed after ELVR with valves. Pulmonary function tests (PFT, St George’s Respiratory Questionnaire (SGRQ, and 6-minute walk tests (6MWT were performed on patients at baseline. The sample was grouped into high and low levels at the median of TL perfusion, ipsilateral nontarget lobe (INL perfusion, and heterogeneity index (HI. These groups were analyzed for association with changes in outcome parameters from baseline to 3 months follow-up. Compared to baseline, patients showed significant improvements in PFT, SGRQ, and 6MWT (all P≤0.001. TL perfusion was not associated with changes in the outcome. High INL perfusion was significantly associated with increases in 6MWT (P=0.014, and high HI was associated with increases in forced expiratory volume in 1 second (FEV1, (P=0.012. Likewise, there were significant correlations for INL perfusion and improvement of 6MWT (r=0.35, P=0.03 and for HI and improvement in FEV1 (r=0.45, P=0.001. This study reveals new attributes that associate with positive outcomes for patient selection prior to ELVR

However, clinically approved contrast agents that allow single-cell detection are currently not available. Therefore, we compared very small iron oxide nanoparticles (VSOP and new multicore carboxymethyl dextran-coated iron oxide nanoparticles (multicore particles, MCP designed by our department for magnetic particle imaging (MPI with discontinued Resovist® regarding their suitability for detection of single mesenchymal stem cells (MSC by MRI. We achieved an average intracellular nanoparticle (NP load of >10 pg Fe per cell without the use of transfection agents. NP loading did not lead to significantly different results in proliferation, colony formation, and multilineage in vitro differentiation assays in comparison to controls. MRI allowed single-cell detection using VSOP, MCP, and Resovist® in conjunction with high-resolution T2*-weighted imaging at 7 T with postprocessing of phase images in agarose cell phantoms and in vivo after delivery of 2,000 NP-labeled MSC into mouse brains via the left carotid artery. With optimized labeling conditions, a detection rate of ~45% was achieved; however, the experiments were limited by nonhomogeneous NP loading of the MSC population. Attempts should be made to achieve better cell separation for homogeneous NP loading and to thus improve NP

There are multiple ways one could possibly define interlobar emphysema heterogeneity, and there is no standardized definition.Purpose: The aim of this study was to derive a formula for calculating an interlobar emphysema heterogeneity index (HI when evaluating a patient for ELVR. Furthermore, an attempt was made to identify a threshold for relevant interlobar emphysema heterogeneity with regard to ELVR.Patients and methods: We retrospectively analyzed 50 patients who had undergone technically successful ELVR with placement of one-way valves at our institution and had received lung function tests and computed tomography scans before and after treatment. Predictive accuracy of the different methods for HI calculation was assessed with receiver-operating characteristic curve analysis, assuming a minimum difference in forced expiratory volume in 1 second of 100 mL to indicate a clinically important change.Results: The HI defined as emphysema score of the targeted lobe (TL minus emphysema score of the ipsilateral nontargeted lobe disregarding the middle lobe yielded the best predicative accuracy (AUC =0.73, P=0.008. The HI defined as emphysema score of the TL minus emphysema score of the lung without the TL showed a similarly good predictive accuracy (AUC =0.72, P=0.009. Subgroup

Angular measurement technology at high resolution for applications such as in hard disk drive manufacturing machines, precision measurement equipment and aspherical process machines requires a rotary encoder with high accuracy, high resolution and high response speed. However, a rotary encoder has angular deviation factors during operation due to scale error or installation error. It has been assumed to be impossible to achieve accuracy below 0.1″ in angular measurement or control after the installation onto the rotating axis. Self-calibration (Lu and Trumper 2007 CIRP Ann. 56 499; Kim et al 2011 Proc. MacroScale; Probst 2008 Meas. Sci. Technol. 19 015101; Probst et al Meas. Sci. Technol. 9 1059; Tadashi and Makoto 1993 J.

Eng. 33 530; Burnashev 2013 Quantum Electron. 43 130) technologies for a rotary encoder have been actively discussed on the basis of the principle of circular closure. This discussion prompted the development of rotary tables which achieve reliable and high accuracy angular verification. We apply these technologies for the development of a rotary encoder not only to meet the requirement of super-high accuracy but also to meet that of super-high resolution. This paper presents the development of an encoder with 2 21 = 2097 152 resolutions per rotation (360°), that is, corresponding to a 0.62″ signal period, achieved by the combination of a laser rotary encoder supplied by Magnescale Co., Ltd and a self-calibratable encoder (SelfA) supplied by The National Institute of Advanced Industrial Science and Technology (AIST). In addition, this paper introduces the development of a rotary encoder to guarantee ±0.03″ accuracy at any point of the interpolated signal, with respect to the encoder at the minimum resolution of 2 33 , that is, corresponding to a 0.0015″ signal period

Full Text Available This study investigated the seasonal dynamics of two populations of Aphanizomenon flos-aquae Ralfs ex Bornet & Flahault var. flos-aquae and four populations of A. flos-aquae var. klebahnii Elenkin in eutrophic water bodies over 1 year from February 2006 to January 2007. The growth of A. flos-aquae var. flos-aquae was promoted at high temperatures even if in one case the biomass development was very low when other co-occurring cyanoprokaryotes (Anabaena spp. and Microcystis spp. were abundant. In contrast, the highest density of the other population of A. flos-aquae var. flos-aquae was observed in August when the population density of M. aeruginosa (Kützing Kützing reached an annual peak. A. flos-aquae var. flos-aquae usually bloomed in summer but could also tolerate low temperatures in the winter, and was present in relatively high densities. The populations of A. flos-aquae var. klebahnii observed in this study can be divided into three groups based on preferred temperature; three populations increased in winter, and the other increased in summer. Large biomasses of the low-temperature-adapted A. flos-aquae were observed mainly during winter when population densities of co-occurring cyanoprokaryotes (Anabaena spp., Microcystis spp. and Planktothrix raciborskii (Woloszynska Anagnostidis & Komárek were relatively low or almost absent. The increase in or existence of cooccurring cyanoprokaryotes during the summer resulted in a decrease of the A. flos-aquae population density. It was revealed that high temperatures (20-25 °C are suitable for maintaining A. flos-aquae var. klebahnii strains isolated from the study ponds, implying that low-temperature-adapted A. flos-aquae can grow over a wide range of water temperatures. The high-temperatureadapted A. flos-aquae var. klebahnii co-existed with M. aeruginosa during summer; however, its peak population density was significantly lower than those in previous years when M. aeruginosa was absent

Through within-twin analyses, we aimed to minimize confounding effects such as twins that share genetic and early environmental exposures.Materials and methods: Using the Swedish Twin Registry, we examined the birth weight of 146,830 twins according to the CD status. CD was defined as having villous atrophy according to a small intestinal biopsy reports.Results: The prevalence of diagnosed CD was 0.5% (n=669, and we included 407 discordant pairs of CD–non-CD twins. Comparing the 669 CD patients with non-CD twins, the association between birth weight and future CD was not statistically significant (odds ratio [OR] per 1000 g increase in birth weight: 1.16; 95% confidence interval [CI]=0.97–1.38. In males, the association was positive and statistically significant (OR=1.50; 95% CI

Preliminary results show significant differences in diversity for many species between contaminated and reference sites. However, more research is needed to draw conclusions about the cause of such observations. Nevertheless, by combining a through site characterisation and exposure assessment with a variety of ecologically relevant biomarker and endpoint measurements, the data produced should be a valuable contribution to international activities looking at the impacts of chronic exposure of ionising radiation on non-human species.

All patients provided their informed consent prior to inclusion. Data were collected from a database. Follow-up data included data from central mortality registries, general practitioners and a specialized clinic. Statistical analysis of the general patient data and the different operations and approaches were performed with the use of chi-square test, Fisher’s exact test, and the Mann–Whitney U test.Results: The median follow-up period in case of open and laparoscopic surgery was found to be 9 and 6 years, respectively. Statistically significant differences were observed for the following parameters in case of open and laparoscopic surgery, respectively: age (median=44 vs. 36 years, range=15–76 vs. 15–72 years; p=0.007, urgency of operation (23 out of 34 planned vs. 6 out of 70 planned; p<0.001, year of resection (median=2003 vs. 2006, range=2000–2010 vs. 2000–2010; p=0.001.

However, although many different synthesis methods, coatings, and functionalization techniques have been described, not many core-shell SPION drug delivery systems are available for clinicians at the moment. Here, bovine serum albumin was adsorbed onto lauric acid-stabilized SPIONs. The agglomeration behavior, zeta potential, and their dependence on the synthesis conditions were characterized with dynamic light scattering. The existence and composition of the core-shell-matrix structure was investigated by transmission electron microscopy, Fourier transform infrared spectroscopy, and zeta potential measurements. We showed that the iron oxide cores form agglomerates in the range of 80 nm. Moreover, despite their remarkably low tendency to aggregate even in a complex media like whole blood, the SPIONs still maintained their magnetic properties and were well attractable with a magnet. The magnetic properties were quantified by vibrating sample magnetometry and a superconducting quantum

For bench to bedside translation of superparamagnetic iron oxide nanoparticles (SPIONs, safety issues have to be comprehensively clarified. To understand concentration-dependent nanoparticle-mediated toxicity, the exact quantification of intracellular SPIONs by reliable methods is of great importance. In the present study, we compared three different SPION quantification methods (ultraviolet spectrophotometry, magnetic particle spectroscopy, atomic adsorption spectroscopy and discussed the shortcomings and advantages of each method. Moreover, we used those results to evaluate the possibility to use flow cytometric technique to determine the cellular SPION content. For this purpose, we correlated the side scatter data received from flow cytometry with the actual cellular SPION amount. We showed that flow cytometry provides a rapid and reliable method to assess the cellular SPION content. Our data also demonstrate that internalization of iron oxide nanoparticles in human

This study was carried out to describe the genetic make-up for this rare MRSA strain.Methods: Four CC15-MRSA isolates collected in Riyadh, Saudi Arabia, between 2013 and 2014 were studied. Two isolates were from clinical infection and 2 from retail meat products. Whole genome sequencing was carried out using Illumina HiSeq2500 genome analyzer.Results: All the CC15-MRSA isolates had the multilocus sequence typing profile ST1535, 13–13-1–1-81-11-13, which is a single locus variant of ST15. Of the 6 contigs related to the SCC element, one comprised a recombinase gene ccrAA, ccrC-PM1, fusC and a helicase, another one included mvaS, dru, mecA and 1 had yobV and Q4LAG7. The SCC element had 5 transposase genes, namely 3 identical paralogs of tnpIS431 and 2 identical paralogs of tnpIS256.

The most common location is the lower back. Pharmacological treatment of this condition is challenging because of the range of causative mechanisms and the difficulty of balancing analgesic efficacy and tolerability. An international panel of clinical pain specialists met in September, 2009, to discuss the treatment of chronic low back pain, and to review preclinical and clinical data relating to the new analgesic, tapentadol. A lack of consensus exists on the best treatment for low back pain. The range of regularly prescribed pharmacological agents extends from nonopioids (paracetamol, NSAIDs, and COX-2 inhibitors to opioids, antidepressants and anticonvulsants. Pain relief may be compromised, however, by an undetected neuropathic component or intolerable side effects. Treatment is potentially life-long and effective analgesics are urgently needed, with demonstrable long-term safety. Combining separate agents with different mechanisms of action could overcome the limitations of present

"It may be that we are seeing an early stage of the cycle before the radio source has turned on," said team member William Forman also of the Harvard-Smithsonian Center for Astrophysics. "Or, it could be a new type of outburst that is not accompanied by strong radio emission." Other members of the team included Alexey Vikhlinin, Maxim Markevitch, Laurence David, Aryeh Warmflash, all of the CfA, and Paul Nulsen of the University of Wollongong in Australia.

Basic research in surface and interface science is highly interdisciplinary, covering the fields of physics, chemistry, biophysics, geo-, atmospheric and environmental sciences, material science, chemical engineering, and more. The various phenomena are interesting by themselves, and they are most important in nearly all modern technologies, as for example electronic, magnetic, and optical devices, sensors, catalysts, lubricants, hard and thermal-barrier coatings, protection against corrosion and crack formation under harsh environments. In fact, detailed understanding of the elementary processes at surfaces is necessary to support and to advance the high technology that very much founds the prosperity and lifestyle of our society. Current state-of-the-art experimental studies of elementary processes at surfaces, of surface properties and functions employ a variety of sophisticated tools. Some are capable of revealing the location and motion of individual atoms. Others measure excitations (electronic, magnetic and vibronic), employing, for example, special light sources such as synchrotrons, high magnetic fields, or free electron lasers. The surprising variety of intriguing physical phenomena at surfaces, interfaces, and nanostructures also pose a persistent challenge for the development of theoretical descriptions, methods, and even basic physical concepts. This second focus issue on the topic of 'Advances in Surface and Interface Science' in New Journal of Physics, following on from last year's successful collection, provides an exciting synoptic view on the latest pertinent developments in the field.

very intense rainfall events cause a single-tailed rather small rise of the hydrograph in the Weierbach. Mixing diagrams suggest a very brief and intense switch from groundwater to soil water contribution. Almost simultaneously to incoming precipitation, terrestrial diatom abundance increases to 20-30% inside the stream. Species composition was also seasonally structured. During winter season (November 2010 and January 2011 events) the diatom drift was characterized and dominated by colony forming species (e.g. Fragilaria nevadensis Linares-Cuesta & Sánchez-Castillo and Fragilariforma virescens (Ralfs) Williams & Round), while summer events were characterized by a large number of small aerophytic species (i.e. Chamaepinnularia evanida (Hustedt) Lange-Bertalot, Eolimna tantula (Hustedt) Lange-Bertalot, Navicula obsoleta Hustedt, Navicula parsura Hustedt and Stauroneis thermicola (Petersen) Lund). Chemical tracers suggest a substantial role of soil water contributions to storm hydrographs in the Weierbach, regardless of the season, with overland flow playing no prominent role at all. Meanwhile, terrestrial diatom abundance in drift samples strongly increases during precipitation events, suggesting a rapid onset of connectivity between the soil surface and the stream. We assume the terrestrial diatoms to be mobilized during precipitation and eventually flushed to the stream through a subsurface network of macropores in the shallow soils and cracks in the fractured and weathered schistose bedrock.

Dark Energy Found Stifling Growth in Universe

Science.gov (United States)

2008-12-01

WASHINGTON -- For the first time, astronomers have clearly seen the effects of "dark energy" on the most massive collapsed objects in the universe using NASA's Chandra X-ray Observatory. By tracking how dark energy has stifled the growth of galaxy clusters and combining this with previous studies, scientists have obtained the best clues yet about what dark energy is and what the destiny of the universe could be. This work, which took years to complete, is separate from other methods of dark energy research such as supernovas. These new X-ray results provide a crucial independent test of dark energy, long sought by scientists, which depends on how gravity competes with accelerated expansion in the growth of cosmic structures. Techniques based on distance measurements, such as supernova work, do not have this special sensitivity. Scientists think dark energy is a form of repulsive gravity that now dominates the universe, although they have no clear picture of what it actually is. Understanding the nature of dark energy is one of the biggest problems in science. Possibilities include the cosmological constant, which is equivalent to the energy of empty space. Other possibilities include a modification in general relativity on the largest scales, or a more general physical field. People Who Read This Also Read... Chandra Data Reveal Rapidly Whirling Black Holes Ghostly Glow Reveals a Hidden Class of Long-Wavelength Radio Emitters Powerful Nearby Supernova Caught By Web Cassiopeia A Comes Alive Across Time and Space To help decide between these options, a new way of looking at dark energy is required. It is accomplished by observing how cosmic acceleration affects the growth of galaxy clusters over time. "This result could be described as 'arrested development of the universe'," said Alexey Vikhlinin of the Smithsonian Astrophysical Observatory in Cambridge, Mass., who led the research.

with a great response: not only did over thirty young colleagues register but also senior scientists registered for the course and were very active in discussions. The workshop was supported financially by Forschungszentrum Jülich and the ExtreMat Integrated Project, a programme for the development and study of new materials for extreme environments. We are very grateful to the staff of Forschungszentrum who helped with the organization. Our most cordial thanks and gratitude go to Yasmin Fattah, Angelika Hallmanns, Gabriele Knauf and Gerd Boeling for all their kindness and efficiency, which helped all of us to enjoy the meeting. We thank most sincerely our colleagues Gerald Pintsuk, Takeshi Hirai and Andrey Litnovsky for their most professional work in the construction and operation of the conference webpage, the preparation of the sessions and for all other elements that were vital for the smooth running of the meeting. We thank very much Marliese Felden and Ralf-Uwe Limbach who very kindly and professionally took care of the photographic documentation of the workshop. The proceedings of this workshop contains 67 peer-reviewed articles covering the contents of most of the invited presentations and a number of poster contributions which were pre-selected by the programme committee. The papers reflect the development and actual status of the field. We thank all participants for their contributions and the referees for their smooth and efficient peer-review. Thank you all for your hard work and co-operation. We are looking forward to seeing you at the next meeting; we invite you to come, though we are not yet able to say 'when' and 'where' we will meet next time. It is a special feature of this conference series that a new meeting is announced only when the community feels that there is substantial new material to be presented and discussed.

particle image velocimetry (PIV), wherein 'instantaneous' planes of the velocity field are obtained. (The planar information, of course, falls short of the volumetric data that would be required for a complete measurement strategy.) In this paper [1] the authors first provide a valuable review of the literature in this area before presenting their original contribution. Operating with the constraint of incomplete information, the authors have significantly advanced this aspect of fluid mechanics measurements by: (i) performing error analysis evaluations of the extant methodologies, and (ii) introducing the use of POD (proper orthogonal decomposition) techniques to smooth the PIV data. Three globally unsteady flow fields are investigated in this paper. Two of the subject flows are simulations where the pressure can be compared with the inferred value using simulated PIV results—with the addition of typical measurement uncertainties—and the third test case is the unsteady flow in a planar diffuser. This paper is a benchmark contribution on the path to accurately inferring pressure values in the interior of a flow field. 2010 Award Award Winner—Measurement Science Achieving high effective Q-factors in ultra-high vacuum dynamic force microscopy Jannis Lübbe, Lutz Tröger, Stefan Torbrügge, Ralf Bechstein, Christoph Richter, Angelika Kühnle and Michael Reichling Fachbereich Physik, Universität Osnabrück, Barbarastraße 7, 49076 Osnabrück, Germany Nanoworld Services GmbH, Schottkystraße 10, 91058 Erlangen, Germany Institut für Physikalische Chemie, Johannes Gutenberg-Universität Mainz, Jakob-Welder Weg 11, 55099 Mainz, Germany This paper [2] presents a detailed methodology to achieve good Q-factors in a scanning force microscope.

velocities of the interacting matter. The astronomer team therefore intends to carry out further adaptive-optics imaging and spectroscopy with the ESO instruments later this year. Great prospects for related research projects The detection of this new object shows that direct proofs for the existence of circumstellar disks in distant star-forming regions are possible with currently available telescopes. It also represents an important step forward for the preparation of scientific programmes devoted to the formation of stars and planets that will soon be carried out with the ESO Very Large Telescope (VLT). The new results demonstrate that the high-resolution images that will be obtained with the future giant telescopes and, especially, with the VLT Interferometer (VLTI) will most likely lead to important breakthroughs in our understanding on the complicated processes of star formation. This will in turn cast new light on how the Sun and the Earth came into existence, more than 4.5 billion years ago. Where to find additional information More details on the investigation of star formation in M8 and the newly discovered proplyd can be found on the World-Wide Web page of the Thüringer Landessternwarte (URL: http://www.tls-tautenburg.de/M8.html Notes: [1] The team consists of Bringfried Stecklum and Steffen Richter (Thüringer Landessternwarte, Tautenburg, Germany), Thomas Henning, Ralf Launhardt and Markus Feldt (Astrophysikalisches Institut und Universitätssternwarte, Friedrich-Schiller-Universität Jena), Thomas L.

Die konzeptionelle Entwicklung und forschungspraktische Erprobung von Video-Dokumentationen und computergestützten Video-Analysen SVEN KOMMER und RALF BIERMANN (Pädagogische Hochschule Freiburg bieten in ihrem Beitrag «Video(technik in der erziehungswissenschaftlichen Forschung» einen Überblick über den methodologisch-methodischen Entwicklungsstand und geben konkrete Einblicke in das Projekt «Medienbiografien mit Kompetenzgewinn», das aktuell im Rahmen des Kompetenzzentrums für Genderforschung und Bildungsfragen (PH Freiburg durchgeführt wird. Ausgehend von der Annahme, dass die ausschliessliche Nutzung von verbalen Selbstexplikationen in qualitativen Interviews nicht ausreicht, um die medialen Handlungspraxen der Befragten adäquat zu erfassen, stellen die Autoren ein Triangulations-Konzept vor, das wesentlich auf der videogestützten Beobachtung von Computerkursen beruht. Über rein methodologische Erörterungen hinausgehend werden die einzelnen Schritte der Datenerhebung sowie die Aufgaben bei der quantitativen Kodierung des aufgenommenen Videomaterials sehr konkret auf dem Hintergrund der Projekterfahrungen beschrieben. Die detaillierte Darstellung der Möglichkeiten der computergestützten Filmanalyse-Programme «Catmovie und Videograph», die für die Auswertung umfangreichen Materials geeignet sind (u.a. SPSS-Files, vermittelt eine Reihe forschungspraktischer Erfahrungswerte, die für die Planung eigener Vorhaben dienlich sein können. In einem Fazit-Kapitel halten KOMMER und BIERMANN im Hinblick auf die analysierten Befunde fest, dass sich erst über die Integration der Videodaten Erkenntnisse ergaben, die bei den Interviews von den Befragten nicht expliziert wurden und auch in einer vertiefenden Interpretation dieser Interviews nur bedingt herausgearbeitet werden konnten.

Weise der Umgang mit Medien hierzu beitragen kann. Und weil Bildung in dieser Tradition grundsätzlich als Selbstbildung verstanden werde, liege es nahe, neben der formellen, institutionalisierten Bildung dem Bereich der informellen Bildung eine entsprechende Beachtung zu schenken. Der Artikel fragt daher nach dem Beitrag, den Computerspiele – und vor allem community-basierte Praxen – für eine Flexibilisierung von Selbst- und Weltsichten sowie für den Aufbau von Orientierungswissen leisten können, und diskutiert abschliessend, inwiefern solche informellen Bildungspotenziale pädagogisch aufgegriffen und unterstützt werden können. Florian Berger und Alexander Marbach gehen davon aus, dass es angesichts der Popularität und hohen Motivationskraft der Computerspiele zwar nahe liege, ihre pädagogische Verwertbarkeit zu prüfen, dass für den pädagogischen Einsatz der digitalen Spiele aber bisher weder theoretisch fundierte Konzepte noch eine hinreichende Forschung existiere. Insbesondere würden Fragen der technischen Machbarkeit zu wenig beachtet, wobei die Schwierigkeit darin bestehe, dass der jeweilige «State of the Art» für Lernspiele als Massstab schon wegen der begrenzten (finanziellen Ressourcen ausscheide, andererseits aber ein Mindeststandard erreicht werden müsse, um die notwendige Akzeptanz beim Anwender zu finden. Vor diesem Hintergrund geht der Beitrag zunächst der Frage nach, was die technische, die kulturelle und die pädagogische Qualität eines digitalen Spiels ausmacht, um dann – aus einer primär ingenieurwissenschaftlichen Perspektive – zu diskutieren, wie bei der Gestaltung von Lernspielen eine gute Balance erreicht werden kann. Ralf Biermann betrachtet Computerspiele in seinem Beitrag nicht aus mediendidaktischer, sondern aus medienpädagogischer Perspektive und stellt ein Konzept vor, mit dem die digitalen Spiele selbst zum Gegenstand einer lernorientierten Auseinandersetzung werden. Die leitende Idee ist es, Wege aufzuzeigen und

: PR Photo 03d/03 shows the southern constellation Indus (The Indian) and its surroundings, as drawn in the famous Uranographia published 1801 of German astronomer Johann Elert Bode. This reproduction was made from original printing plates held by the library of the Astrophysical Institute Potsdam (Germany). The binary stellar system Epsilon Indi is associated with one of the arrows in the Indian's hand. However, because of its proximity, only 12 light-years away, it is moving so fast across the sky that it is now located someway below the arrows. In only a few thousand years, it will have moved out of the Indus constellation and into the neighbouring constellation Tucana (The Toucan). The constellation Indus lies deep in the southern sky, nestled between three birds, Grus (The Crane), Tucana (The Toucan) and Pavo (The Peacock), cf. PR Photo 03d/03. First catalogued in 1595-1597 by the Dutch navigators Pieter Dirkszoon Keyser and Frederick de Houtman, this constellation was added to the southern sky by Johann Bayer in his book 'Uranometria' (1603) to honour the Native Americans that European explorers had encountered on their travels. In particular, it has been suggested that it is specifically the native peoples of Tierra del Fuego and Patagonia that are represented in Indus, just over two thousand kilometres south of La Silla where the first spectroscopic observations of Epsilon Indi B were made some 400 years later. In the later drawing by Bode shown here, Epsilon Indi, the fifth brightest star in Indus, is associated with one of the arrows in the Indian's hand. More information The information in this press release is based on a paper ("Epsilon Indi B: a new benchmark T dwarf" by Ralf-Dieter Scholz and co-authors), soon to be published in the European journal Astronomy & Astrophysics (Letters). It is available on the web in preprint form at http://babbage.sissa.it/abs/astro-ph/0212487.

The conference 'From DNA-Inspired Physics to Physics-Inspired Biology' (1-5 June 2009, International Center for Theoretical Physics, Trieste, Italy) that myself and two former presidents of the American Biophysical Society—Wilma Olson (Rutgers University) and Adrian Parsegian (NIH), with the support of an ICTP team (Ralf Gebauer (Local Organizer) and Doreen Sauleek (Conference Secretary)), have organized was intended to establish stronger links between the biology and physics communities on the DNA front. The relationships between them were never easy. In 1997, Adrian published a paper in Physics Today ('Harness the Hubris') summarizing his thoughts about the main obstacles for a successful collaboration. The bottom line of that article was that physicists must seriously learn biology before exploring it and even having an interpreter, a friend or co-worker, who will be cooperating with you and translating the problems of biology into a physical language, may not be enough. He started his story with a joke about a physicist asking a biologist: 'I want to study the brain. Tell me something about it!' Biologist: 'First, the brain consists of two parts, and..' Physicist: 'Stop. You have told me too much.' Adrian listed a few direct avenues where physicists' contributions may be particularly welcome. This gentle and elegantly written paper caused, however, a stormy reaction from Bob Austin (Princeton), published together with Adrian's notes, accusing Adrian of forbidding physicists to attack big questions in biology straightaway. Twelve years have passed and many new developments have taken place in the biologist-physicist interaction. This was something I addressed in my opening conference speech, with my position lying somewhere inbetween Parsegian's and Austin's, which is briefly outlined here. I will first recall certain precepts or 'dogmas' that fly in the air like Valkyries, poisoning those relationships. Since the early seventies when I was a first year Ph

(2012) B.4 Extracellular Phosphorylation in the Murine Synaptosome Jonathan C Trinidad1, Ralf Schoepfer2, Alma L Burlingame3, Katalin F Medzihradszky3* 1Department of Chemistry, Indiana University, Bloomington, IN, USA; 2Department of Pharmacology, University College London, England, UK; 3Department of Pharmaceutical Chemistry, School of Pharmacy, University of California San Francisco, CA, USA Post-translational modifications (PTMs) play key regulatory roles in cellular localization and/or biological function of proteins. The site of modification within a protein; their fixed or transient nature; the stoichiometry and potential crosstalk between modifications have been the focus of numerous large-scale studies. Most of this research is focused on PTMs involved in intracellular processes, such as phosphorylation, methylation, GlcNAcylation, acetylation, and ubiquitination. Of these, phosphorylation is the most studied due to the biological importance of this modification as well as the availability of tools for such studies. While the majority of protein phosphorylation occurs on intracellular proteins, phosphorylation of secreted proteins is well established. Well-characterized examples include the secreted milk protein, beta-casein, and the serum protein fetuin. Our current understanding of the biological role of extracellular phosphorylation, as well as knowledge regarding the process by which they are modified, is incomplete. A kinase known as FAM20 has been identified and is localized to the Golgi as well as secreted. It has been shown to phosphorylate extracellular proteins with a SXE motif. We recently conducted extensive studies on the interplay between intracellular phosphorylation and GlcNAcylation on proteins isolated from murine synaptosomes. This data also allowed us to identify specific glycan structures on more than 500 secreted or transmembrane proteins. We have subsequently examined the extent to which phosphorylation was present in our
