Quelques facteurs affectant la mobilité sociale des femmes dans le monde rural soviétique
Authors: Dunn Ethel
Published: November 2010

Factors affecting Social Mobility for Women in the Soviet Countryside.

This study is based on a wide range of sociological, ethnographic, and public- health literature. The author re-examines her original position that "the peasant is a man in transition", and concludes that the proposition should undergo a gender change. Soviet rural women are not being given access to technical training, in spite of official desire. Several reasons are given for this, and the author concludes that in order to achieve their maximum potential, rural women are having to leave for the cities. The situation is not likely to change unless the biological role of women is altered.
La Constitution démocratique de la Pologne. (Un projet peu connu)
Authors: Bitner Waclaw
Published: November 2010

L'Etat polonais est ressuscité en 1918 après 123 ans d'inexistence légale. Sa première Constitution a été adoptée par la Diète le 21 mars 1921. Cette Constitution démocratique, inspirée des textes français et belge, s'est avérée peu adaptée aux conditions d'un Etat confronté à des difficultés considérables, internes aussi bien qu'externes. A partir du coup d'Etat de mai 1926, entrepris avec succès par le maréchal Pilsudski, la Constitution de 1921 a été progressivement modifiée dans le sens d'un certain renforcement du pouvoir du président de la République. Pilsudski, d'ailleurs, souhaitait que le renforcement de l'exécutif soit poussé encore plus loin.

Certains membres du Parlement, dont l'auteur de l'article, ont entrevu la nécessité d'amender la Constitution de 1921 et d'en protéger les grands principes démocratiques et républicains. Un projet a donc été élaboré en 1929 et a été présenté à la Diète le 18 février 1930 avec l'accord du centre-gauche. Après avoir, d'abord, été accepté par Pilsudski, il a finalement été rejeté à la suite d'une série de circonstances relatées par l'auteur. C'est le texte de ce projet qui est publié ici.
Le nouveau rôle des transferts de technologie dans la vie économique hongroise
Authors: Biró Gerd
Published: November 2010

La situation actuelle de l'économie mondiale a donné une impulsion nouvelle aux transferts de technologie. A cet égard, il faudrait entre autres prendre en considération que la hausse des prix des matières premières et des énergies primaires hâte considérablement les changements structurels dans la production et la technologie. De même, certains pays en voie de développement sont désormais capables de financer leurs besoins et représentent, en s'efforçant de rattraper leur retard, un facteur dynamique de la demande en ce domaine.

Dans ce cadre global, l'auteur analyse plus spécifiquement la politique de la Hongrie en matière de transfert de technologie sous ses diverses formes (achat de licences étrangères, création de sociétés mixtes, etc. et ventes par la Hongrie de sa propre technologie, notamment aux pays en voie de développement).
Transferts de technologie, endettement et perspectives du commerce Est-Ouest
Authors: Zaleski Eugène
Published: November 2010

L'expansion considérable du commerce Est-Ouest intervenue au cours de la première moitié des années 1970 a été rendue possible par l'offre d'abondants crédits occidentaux. Mais elle traduit aussi les besoins considérables des pays de l'Est en technologie occidentale et en capitaux destinés à leur développement.

Cette expansion a cependant fait naître un énorme endettement qui a tendance à croître ces dernières années, malgré les efforts des pays de l'Est pour réduire le déficit de leurs balances commerciales. La dette dont le niveau a depuis longtemps dépassé les limites d'un endettement jugé « sain » est considérée cependant comme « acceptable > par les hommes d'affaires occidentaux qui comptent, en partie au moins, sur l'Union Soviétique pour renflouer les ressources de ses partenaires du CAEM en difficulté.

Devant l'ampleur du déficit à prévoir pour les années 1980, certains auteurs s'interrogent sur l'attitude possible des Occidentaux face à un éventuel défaut de paiement de certains pays de l'Est. Ils prévoient une attitude fortement influencée par des considérations de politique extérieure (ne pas renforcer la dépendance des pays du CAEM envers PU.R.S.S.) et de politique intérieure (soutenir leurs banques et entreprises en difficulté, même celles ne bénéficiant pas de garanties officielles de crédit). Un contingentement des crédits accordés à l'Est pourrait être appliqué, de même qu'un plan prévoyant des achats massifs et exceptionnels pour éponger, partiellement au moins, la dette difficilement recouvrable.

C'est l'attitude des pays de l'Est qui sera cependant déterminante dans les années à venir. La réduction actuelle du déficit de leurs balances commerciales et la pression pour la conclusion d'accords de compensation et de contre-achats ne constituent que des remèdes partiels. Ils seront acculés au choix : se replier vers l'isolement économique au sein de la zone du CAEM ou s'ouvrir davantage à une division internationale du travail. Les défauts de la planification administrative et les besoins aigus en technologie et en capital pourraient les obliger à choisir la seconde solution, à moins que les Occidentaux n'offrent à nouveau des crédits abondants et bon marché, ce qui ne ferait que reporter l'échéance.
Quelques observations sur la fonction internationale des monnaies des pays de l'Europe de l'Est
Authors: Dunajewski Henryk
Published: November 2010

L'auteur analyse les conditions de convertibilité des monnaies nationales des pays du CAEM, d'une part et du rouble transférable, d'autre part. Il essaie de prouver que les monnaies de ces pays ne sont convertibles qu'à sens unique (Particulier-»- Banque d'Etat, mais non obligatoirement : Banque d'Etat-»- Particulier). Faute de convertibilité à deux sens et de fixation du cours des changes en conformité avec la loi du marché, les pays du CAEM perdent plus qu'ils ne gagnent. Ils auront, par conséquent, tout intérêt à supprimer les contraintes empêchant leur monnaie de jouer le rôle de devise.

Leur unité commune de compte, le rouble transférable, a certes la qualité de devise zonale, institutionnelle et abstraite. Mais, pour l'instant, elle n'est convertible ni en devises occidentales ni même en monnaies nationales des pays dont elle constitue l'unité commune. Ce défaut présente un obstacle sérieux à équilibrer multilatéralement les relations commerciales intra et extra CAEM.
Transfixation cast technique for arthrodesis of the distal interphalangeal joint of horses
Authors: Schumacher J. , Watkins J. P. , Easter J. L.
Published: November 2010

Surgical arthrodesis of the distal interphalangeal (DIP) joint by transfixation casting was used to salvage a three-year-old filly and a yearling filly that were chronically lame because of infection of the DIP joint for breeding. Unlike previously described techniques for arthrodesis of the DIP joint, the technique used did not require insertion of implants across the joint, which may have contributed to the successful outcome.
Theoretical discrepancy between cage size and efficient tibial tuberosity advancement in dogs treated for cranial cruciate ligament rupture
Authors: Mills J. , Busoni V. , Brunel L. , Balligand M. , Etchepareborde S.
Published: November 2010

Objectives: To calculate the difference between the desired tibial tuberosity advancement (TTA) along the tibial plateau axis and the advancement truly achieved in that direction when cage size has been determined using the method of Montavon and colleagues. To measure the effect of this difference on the final patellar tendon-tibial plateau angle (PTA) in relation to the ideal 90°.

Methods: Trigonometry was used to calculate the theoretical actual advancement of the tibial tuberosity in a direction parallel to the tibial plateau that would be achieved by the placement of a cage at the level of the tibial tuberosity in the osteotomy plane of the tibial crest. The same principle was used to calculate the size of the cage that would have been required to achieve the desired advancement. The effect of the difference between the desired advancement and the actual advancement achieved on the final PTA was calculated.

Results: For a given desired advancement, the greater the tibial plateau angle (TPA), the greater the difference between the desired advancement and the actual advancement achieved. The maximum discrepancy calculated was 5.8 mm for a 12 mm advancement in a case of extreme TPA (59°). When the TPA was less than 31°, the PTA was in the range of 90° to 95°.

Clinical significance: A discrepancy does exist between the desired tibial tuberosity advancement and the actual advancement in a direction parallel to the TPA, when the tibial tuberosity is not translated proximally. Although this has an influence on the final PTA, further studies are warranted to evaluate whether this is clinically significant.
The use of computed tomography in the diagnosis of pelvic fractures involving the acetabulum in two fillies
Authors: Kircher P. R. , Fürst A. , Trump M.
Published: November 2010

Two fillies with hindlimb lameness and a tentative diagnosis of a pelvic fracture involving the acetabulum were examined using computed tomography (CT). The use of CT for these two cases revealed the exact course of the fractures and fissures, as well as the size and position of fragments, thus allowing for definitive diagnosis.
Improving surgical reduction in radial fractures using a ‘dowel’ pinning technique in miniature and toy breed dogs
Authors: DeCamp C. E. , Rooks R. , Yu J.
Published: November 2010

Objectives: A retrospective approach was used to detail and evaluate a ‘dowel’ pinning technique in distal radial fractures in miniature and toy breed dogs.

Methods: Medical records and radiographs from 2003–2009 of miniature and toy breed dog radial fractures were examined. Sixty cases were divided into two groups: 51 radial fractures repaired with a ‘dowel’ pinning and external skeletal fixation (ESF) and nine radial fractures repaired with closed reduction and ESF. Each dog was evaluated and radiographic images were obtained at presentation, postoperatively, and at 1, 2, 4, 8, and 12 weeks postoperatively. Signalment, reduction, alignment, time to clinical bone healing and ESF removal, and implant morbidity were determined for each group.

Results: Radial fractures repaired with a ‘dowel’ pin and ESF had improved reduction compared to closed reduction and ESF alone (p <0.0001 as evaluated with lateral radiographs and p <0.0004 with cranial/caudal radiographs). Both surgical groups resulted in good clinical outcome with low morbidity, however it was observed that the time to clinical union and ESF removal was an average of 2.5 weeks less with closed reduction technique compared to the open reduction and ‘dowel’ pinning technique (p <0.031).

Clinical Significance: Incorporating a ‘dowel’ pin to the surgical repair enhances the reduction of distal radial fractures in miniature and toy breed dogs and results in excellent clinical outcomes but causes a small delay in bone healing.
Preparation and characterization of supported magnetic nanoparticles prepared by reverse micelles
Authors: Wiedwald Ulf , Han Luyang , Biskupek Johannes , Kaiser Ute , Ziemann Paul
Published: November 2010

Monatomic (Fe, Co) and bimetallic (FePt and CoPt) nanoparticles were prepared by exploiting the self-organization of precursor loaded reverse micelles. Achievements and limitations of the preparation approach are critically discussed. We show that self-assembled metallic nanoparticles can be prepared with diameters d = 2–12 nm and interparticle distances D = 20–140 nm on various substrates. Structural, electronic and magnetic properties of the particle arrays were characterized by several techniques to give a comprehensive view of the high quality of the method. For Co nanoparticles, it is demonstrated that magnetostatic interactions can be neglected for distances which are at least 6 times larger than the particle diameter. Focus is placed on FePt alloy nanoparticles which show a huge magnetic anisotropy in the L10 phase, however, this is still less by a factor of 3–4 when compared to the anisotropy of the bulk counterpart. A similar observation was also found for CoPt nanoparticles (NPs). These results are related to imperfect crystal structures as revealed by HRTEM as well as to compositional distributions of the prepared particles. Interestingly, the results demonstrate that the averaged effective magnetic anisotropy of FePt nanoparticles does not strongly depend on size. Consequently, magnetization stability should scale linearly with the volume of the NPs and give rise to a critical value for stability at ambient temperature. Indeed, for diameters above 6 nm such stability is observed for the current FePt and CoPt NPs. Finally, the long-term conservation of nanoparticles by Au photoseeding is presented.
RADIONUCLIDE DISTRIBUTION IN THE SOIL ON THE STABATISHKES SITE IN THE VICINITY OF THE IGNALINA NPP
Authors: Aliončik Jevgenij , Bataitienė Ingrida P. , Butkus Donatas
Published: November 2010

A near surface repository for low and intermediate-level short-lived radioactive waste will be built on the Stabatiškės site in the vicinity of Ignalina NPP during decommissioning works. The reservoir can also be used for the waste stored in the temporary repositories of the Ignalina NPP. Engineering and nature protective barriers are used in the repository for radioactive waste, however, radionuclides can spread into the environment, extend in the biosphere and cause (define) the external power light exposure of the environment due to the natural and premature (prescheduled) degradation of the engineering barriers of the repository. The properties of the soil (acidity, quantity of organic substances, humidity) are being investigated for estimating the possible migration and dispersion of radionuclides. The activity of radionuclides in the soil is also estimated before building the repository.
Natural and artificial radionuclides make the pollution of the soil, and therefore the accumulation and vertical migration of artificial (137Cs, 60Co) and natural (226Ra, 232Th, 40K) radionuclides are being researched in the soil on the Stabatiškės site.
ACOUSTIC PROPERTIES OF A RENOVATED BUILDING
Authors: Januševičius Tomas , Butkus Donatas
Published: November 2010

The article explores the effects of partitions, ceilings and facades on noise insulation in the renovated different buildings. The conducted experiments were aimed at analyzing partitions of 120 mm brick mounted gypsum panels while other walls were 520 mm thick and plastered on both sides. Under natural conditions, sound insulation factors of facades were measured and compared according to comfort classes. The obtained results revealed that thick brick walls of 520 mm insulated the sound of 58 decibels (dB) (class B). In contrast, 120 mm brick masonry partition reduced sound only to 48 dB which is class E and agrees with the lowest class of sound insulation. We also calculated the sound insulation factor applying three formulas considering the mass law of sound insulation and comparing it with other previous studies. The paper examines and discusses the findings of the performed calculations and measurements.
ASSESSING THE AMOUNT OF CHEMICAL ELEMENTS IN BIODEGRADABLE AGRICULTURAL WASTES AND ASH
Authors: Kvasauskienė Rasa , Baltrėnas Pranas
Published: November 2010

Biodegradable agricultural wastes such as manure, has long been used as an organic fertilizer that improves soil structure, enriches the soil with micro-organisms and micro-elements necessary for plants and promotes humus formation. Manure can also be successfully used as a renewable energy source directly combusting and extracting energy. The carried out investigation showed that the incineration of manure remaining in ashes could also be used as a fertilizer. Waste combustion reduces its volume to 80–90%. Also, the investigation revealed that the amount of chemical elements (Na, Mg, Si, P, K, Ca, Ti, Mn, Fe) decreased after combustion. However, the concentration of these elements in ashes is higher than that in raw manure.

PECULIARITIES OF THE THERMAL REGIME OF THE SURFACE SEDIMENTS IN LAKE TAPELIAI
Authors: Moisejenkova Anastasija , Tarasiuk Nikolaj , Girgždys Aloyzas
Published: November 2010

The article discusses the process of heat transfer in the water sediment system having an impact on the input of nutrients and mineral substances from sediments to the bottom water layer. Therefore, conductivity sharply increases on the surface of bottom sediments and reaches more than 400 μS∙cm–1. The heat exchange process is analyzed in Lake Tapeliai classified as a “temporally warm” lake (see K. Kilkus). The paper defines heat transfer from bottom sediments to water applying the convection method and describes isotherm deepening of 4 ºC into sediments. The temperature of surface sediments in Lake Tapeliai was 3,3–3,9 ºC in 2007–2009, whereas the isotherm of 4 ºC slid 20–30 cm deeper to bottom sediments.
THE IMPACT OF CHEMICAL PHOSPHORUS REMOVAL ON THE PROCESS OF ANAEROBIC SLUDGE DIGESTION
Authors: Ofverstrom Svetlana , Sapkaitė Ieva , Dauknys Regimantas
Published: November 2010

The paper investigates the efficiency of the mixture of primary sludge and excess activated sludge in Vilnius WWTP with reference to the anaerobic digestion process. Sludge digestion was carried out under laboratory conditions using anaerobic sludge digestion model W8 (Armfield Ltd., UK). Laboratory analyses consist of two periods – the anaerobic digestion of the un-dosed and Fe-dosed sludge mixture. The results of digestion were processed using the methods of statistical analysis. The findings showed reduction in volatile solids approx. by 6% when dosing min FeCl3·6H2O and 15% when dosing max FeCl3·6H2O into feed sludge. Gas volume produced during the digestion of the un-dosed sludge was 90–160 ml/d and 60–125 ml/d in min Fe-dosed sludge and 45-95 ml/d. Also, correlation between VS loadings and biogas production was found. A rise in VS loading from 0,64 g/l/d to 1,01 g/l/d increased biogas production from 90 ml/d to 140–160 ml/d.
La investigación sobre análisis de contenido y los lenguajes documentales en las publicaciones periódicas españolas de información y documentación (1982-1984)
Authors: Sánchez Casabón A. I. , García Marco J.
Published: November 2010

Se analiza la producción bibliográfica sobre análisis de contenido y lenguajes documentales llevada a cabo en España entre 1982 y 1994 a partir de los artículos publicados en siete revistas españolas de información y documentación. Se estudia su distribución por revistas, años, número de autores por artículo, temas, lugares y centros de investigación, con los siguientes resultados: a) la producción alcanza sus cotas máximas entre 1988 Y 1990; b) Madrid y Barcelona, seguidos a cierta distancia por Granada, centralizan casi toda la producción; c) la mayor parte de los artículos son trabajos en colaboración, y tienen carácter esporádico; y d) la CDU y los tesauros son, con mucho, los temas más tratados, seguidos a gran distancia por los resúmenes. En definitiva, ni el análisis de contenido ni los lenguajes documentales son objeto de especial atención en las publicaciones seleccionadas. Con la excepción de la labor de los equipos de trabajo del CINDOC y de algunas personalidades individuales de gran relevancia, se echa de menos la existencia de líneas de investigación consolidadas. Por todo ello, se encarece la formación de equipos de investigación estables, la promoción de foros de discusión permanentes y, quizá, la aparición de alguna publicación periódica de carácter especializado que promocione y canalice la investigación en el campo. Finalmente, se adjunta en apéndice un anexo bibliográfico completo.

Inter-annual variation of shoot density and biomass, nitrogen and phosphorus content of the leaves, and epiphyte load of the seagrass Posidonia oceanica (L.) Delile off Mallorca, western Mediterranean
Authors: Terrados Jorge , Medina-Pons Francisco Javier
Published: November 2010

The epiphyte load, the ash content of the epiphytes, the leaf biomass, the nitrogen and phosphorus content of the leaves, and the density of shoots of the Mediterranean seagrass Posidonia oceanica (L.) Delile were monitored yearly from 2003 to 2008 in two shallow meadows off Mallorca (western Mediterranean) with the aim of identifying the responses of P. oceanica meadows to mid-term environmental variability. Inter-annual variability of P. oceanica meadows was significant for most of the descriptors examined: shoot biomass, epiphyte load, nitrogen and phosphorus content of the leaves, and shoot density. Shoot density increased by a factor of 2 and epiphyte load by a factor of 4 from 2003 to 2008. P. oceanica descriptors were generally not correlated with each other or with the average sea surface temperature during August. Long-term data series of descriptors of P. oceanica status are essential to improve understanding about the response of this important Mediterranean coastal ecosystem to natural and anthropogenic disturbances and to assess the effects of rapid global environmental change.

Grammaire et degré de spécialisation
Authors: Pic Elsa , Furmaniak Grégory
Published: November 2010

Cette étude s’interroge sur la réalité de langues transversales transcendant les langues de spécialité et fondées sur la notion de degré de spécialisation. Existe-t-il une grammaire propre aux textes de vulgarisation et une grammaire propre aux textes spécialisés, quelle que soit la discipline envisagée ? Quels marqueurs grammaticaux sont susceptibles de coder les différences linguistiques entre les divers degrés de spécialisation ? L’hypothèse examinée est que les marqueurs référentiels (comme les temps) sont plutôt révélateurs des différences entre les disciplines, alors que les marqueurs intersubjectifs (comme les modaux) sont plutôt sensibles au degré de spécialisation d’un discours donné. L’analyse d’un corpus composé de textes spécialisés et de textes de vulgarisation en histoire et en philosophie ne confirme que partiellement cette hypothèse de départ : les marqueurs, qu’ils soient référentiels ou intersubjectifs, semblent dans tous les cas plus liés à la discipline qu’au degré de spécialisation. De nouvelles pistes sont alors proposées pour parvenir à cerner les traces linguistiques des divers degrés de spécialisation.
Ocular Manifestations and Pathology of Adult T-cell Leukemia/Lymphoma Associated with Human T-lymphotropic virus Type 1
Authors: Liu Melissa M. , Furusato Emiko , Cao Xiaoguang , Shen Defen , Chan Chi-Chao
Published: November 2010

The human T-cell lymphotropic virus type 1 (HTLV-1), endemic in defined geographical areas around the world, is recognized as the etiologic agent of adult T-cell leukemia/lymphoma (ATL), or HTLV-1. ATL is a rare adult onset T-cell malignancy that is characterized by the presence of ATL flower cells with T-cell markers, HTLV-1 antibodies in the serum, and monoclonal integration of HTLV-1 provirus in affected cells. Ocular manifestations associated with HTLV-1 virus infection have been reported and include HTLV-1 uveitis and keratoconjunctivitis sicca, but reports of ocular involvement in ATL are exceedingly rare. This article describes the ocular manifestations and pathology of ATL. We also report for the first time a case of a 34-year-old male with systemic ATL and prominent atypical lymphoid cell infiltration in the choroid. To our knowledge, this is the first report defining prominent choroidal involvement as a distinct ocular manifestation of ATL. ATL may masquerade as a variety of other conditions, and molecular techniques involving microdissection and PCR have proven to be critical diagnostic tools. Inter -national collaboration will be needed to better understand the presentation and diagnosis of this rare malignancy.
DECREASED CD10 EXPRESSION IN THE BONE MARROW NEUTROPHILS OF HIV POSITIVE PATIENTS
Authors: Van de Vyver Annemarie , Visser Adele
Published: November 2010

Background: HIV-1 infection is associated with various quantitative and qualitative changes in haemopoietic cells. Clear distinction between primary myelodysplastic syndrome (MDS) and secondary dysplasia may not always be possible. Adjunctive analyses used in the diagnosis of MDS include cytogenetics and flow cytometry (FCM). Much focus has been placed on establishing FCM guidelines aiding in the diagnosis of MDS, and to distinguish this condition from secondary dysplastic changes. One of the parameters often cited is the CD10 expression on the granulocyte population, as this marker denotes granulocytic maturation. Aims: To determine the expression level of CD10 on granulocytes in HIV positive patients. Methods: In total, 117 HIV-1 positive and 29 HIV-1 negative patients were included in this study. Bone marrow aspirate samples were evaluated in terms of morphological abnormality as well as CD10 expression on the granulocytic population. Results: The average CD10 expression among the HIV-1 positive patients were markedly reduced, at 18.4%, and 113 patients (96.6%) of these patients had expression levels below 50%. Discussion: Disease conditions causing secondary dysplasia, especially HIV-1 infection, is associated with a marked reduction in CD10 expression on the granulocyte population independent from the presence of myelodysplastic features. This marker is therefore of doubtful significance as a diagnostic tool in distinguishing between primary and secondary dysplasia.
Die kerklike stimulasie van eietydse transformasieprosesse, en die geleentheid wat dít aan nywerheidsbediening bied
Authors: Müller Michau , Pieterse Hennie J.C.
Published: November 2010

The stimulation of the modern transformation processes by the church and the opportunity this presents to industrial mission The church had reacted to both political and industrial change. Localised theology was the answer to a restricted political dispensation, and the final result was the application of liberation theology. The Kairos Document, the Evangelical Witness, the Belhar Confession and Church and Society express the different churches’ viewpoints about the apartheid regime. This contextual focus on the same political dispensation unleashed church influence during the establishment of a national democratic dispensation. The different efforts to deal with industrial change by means of church renewal have finally paved the way for the development of a new industrial mission, vision and approach. This has resulted in the forming of an interchurch industrial organisation, and far-reaching possibilities within the industrial environment.
Dating the Priestly text in the pre-exilic period: Some remarks about anachronistic slips and other obstacles
Authors: Meyer Esias E.
Published: November 2010

This article engages with the work of scholars such as Jacob Milgrom and Avi Hurvitz on dating the Priestly text (P) in the pre-exilic period. In response to Wellhausen�s argument that P is guilty of archaising, Milgrom and Hurvitz have always maintained that there would be some �anachronistic slips�. In this article the author points out a few examples from Leviticus which could be understood as �anachronistic slips�. The author also shows the difficulties one encounters when attempting to interpret a text such as Leviticus 26 in the pre-exilic period.

Authors: Beran Rudolf J. , Klüppelberg Claudia , Polonik Wolfgang
Published: November 2010

Technological developments have created a constant incoming stream of complex new data structures that need analysis. Modern statistics therefore means mathematically sophisticated new statistical theory that generates or supports innovative data-analytic methodologies for complex data structures. Inherent in many of these methodologies are challenging numerical optimization methods. The proposed workshop intends to bring together experts from mathematical statistics as well as statisticians involved in serious modern applications and computing. The primary goal of this meeting was to advance the mathematical and methodological underpinnings of modern statistics for complex data. Particular focus was given to the advancement of theory and methods under non-stationarity and complex dependence structures including (multivariate) ﬁnancial time series, scientiﬁc data analysis in neurosciences and bio-physics, estimation under shape constraints, and highdimensional discrimination/classiﬁcation.

Mathematical Aspects of General Relativity
Authors: Chruściel Piotr T. , Isenberg James , Rendall Alan
Published: November 2010

Mathematical relativity, the subject of this conference, has recently become more and more devoted to the theory of nonlinear evolution equations, with global questions becoming ever more accessible. This is reﬂected by the fact that more than half of the talks given were concerned with the global dynamics of solutions of evolution equations related more or less directly to the Einstein equations of general relativity. Progress was reported in understanding subjects such as black holes, gravitational radiation, cosmology and the relation of general relativity to Newtonian gravitational theory.
Design and Analysis of Infectious Disease Studies
Authors: Eichner Martin , Halloran M. Elizabeth , O'Neill Philip D.
Published: November 2010

This workshop gathered 45 participants from 16 countries and had a correspondingly multifaceted program covering various infectious diseases, public health applications, and methodological innovations. The discussions and presentations focused on the importance of mathematical models and statistical analyses in understanding the complex transmission systems of infectious diseases and in planning eﬀective intervention strategies. Many diﬀerent statistical and mathematical approaches were covered. The general unifying theme is that the analyses and models take into account the underlying transmission of the infectious agent among the hosts and/ or vector populations.
Complexity Theory
Authors: Bürgisser Peter , von zur Gathen Joachim , Goldreich Oded , Sudan Madhu
Published: November 2010

Computational Complexity Theory is the mathematical study of the intrinsic power and limitations of computational resources like time, space, or randomness. The current workshop focused on recent developments in various sub-areas including arithmetic complexity, Boolean complexity, communication complexity, cryptography, probabilistic proof systems, pseudorandomness, and quantum computation. Many of the developements are related to diverse mathematical ﬁelds such as algebraic geometry, combinatorial number theory, probability theory, quantum mechanics, representation theory, and the theory of error-correcting codes.
Convex Geometry and its Applications
Authors: Ball Keith M. , Henk Martin , Ludwig Monika
Published: November 2010

The geometry of convex domains in Euclidean space plays a central role in several branches of mathematics: functional and harmonic analysis, the theory of PDE, linear programming and, increasingly, in the study of other algorithms in computer science. High-dimensional geometry, both the discrete and convex branches of it, has experienced a striking series of developments in the past 10 years. Several examples were presented at this meeting, for example the work of Rudelson et al. on conjunction matrices and their relation to conﬁdential data analysis, that of Litvak et al. on remote sensing and a series of results by Nazarov and Ryabogin et al. on Mahler’s conjecture for the volume product of domains and their polars.
Mini-Workshop: Modeling and Understanding Random Hamiltonians: Beyond Monotonicity, Linearity and Independence
Authors: Stolz Günter , Veselić Ivan
Published: November 2010

The mini-workshop was devoted to the spectral analysis of random Schr¨dinger-type operators. While this topic has been intensively studo ied by physicists and mathematicians for several decades, more recently there has been particular attention devoted to models where the random parameters enter the model in a non-monotone or non-linear way. Most of the established methods applied for random operators, in fact, hinge on the presence of monotonicity w. r. t. randomness. Thus the treatment of non-monotone models forces a deeper analysis of the structure of random Hamiltonians and, in particular, the interplay of the kinetic and the potential energy parts.
Mini-Workshop: Geometry of Quantum Entanglement
Authors: Buchleitner Andreas , Szarek Stanislaw J. , Werner Elisabeth , Zyczkowski Karol
Published: November 2010

The workshop aimed at developing interactions between researchers from quantum information theory and from asymptotic geometric analysis. A central notion discussed was the phenomenon of quantum entanglement, which naturally leads to geometric considerations in high-dimensional vector spaces. In these spaces, phenomena such as concentration of measure become prominent and may invalidate our low-dimensional intuition.
Intrinsic characteristic classes of a local Lie group
Authors: Abadoğlu Ender , Ortaçgil Ercüment
Published: November 2010

For a local Lie group

M

we define cohomology classes

[w_{2k+1}] \in H^{2k+1}_{dR}  (M,ℝ)

. We show that

[w_1]

is an obstruction to globalizability and give an example where

[w_1] ≠ 0

. We also show that

[w_3]

coincides with Godbillon–Vey class in a particular case. These classes are secondary as they emerge when curvature vanishes.
Exponential decay of hyperbolic times for Benedicks–Carleson quadratic maps
Authors: Freitas Jorge Milhazes
Published: November 2010

We consider the Benedicks–Carleson quadratic maps and prove that the tail of Hyperbolic Times, introduced in [5], decays exponentially fast. This improves a previous work [14], where subexponential estimates for this tail were obtained and allows to use the theory developed by Alves et al as another approach to recover statistical properties of these maps like exponential Decay of Correlations, Large Deviations, Central Limit Theorem, Statistical Stability and continuity of metric entropy.

Authors: Karge T. , Siegmund B. , Preiss J. , Hoffmann J.C. , Zeitz M. , Fölsch U.R. , Höhne W.J.
Published: November 2010

Background: The complexity and quality requirements for the development of clinical practice guidelines steadily increase. Internet technologies support this process by optimizing the development process.

Objective: The aim of this internet based solution was to facilitate the development of clinical practice guidelines.

Methods: An internet portal was developed allowing for a shared workplace to support clinical practice guideline authoring. It is based on a Content Management System and combines different tools for document handling and editing, communication as well as process and team steering.

Results: Until now, the internet portal has been successfully implicated in the development of six evidence- and consensus-based clinical practice guidelines. Additional German and European clinical practice guidelines are currently generated with support of the internet portal. The available tools allow for a flexible design of the scheduled workflow, depending on the requirements of the respective group. An additional strength of the platform is the advantage to transfer all data from a previous version of a guideline into the next ‘life-cycle‘.

Conclusion: The application of the portal results in a considerable reduction of costs and development time of the resulting clinical practice guidelines.
Different photolysis kinetics at the surface of frozen freshwater vs. frozen salt solutions
Authors: Kahan T. F. , Kwamena N.-O. A. , Donaldson D. J.
Published: November 2010

Abstract. Reactions at air-ice interfaces can proceed at very different rates than those in aqueous solution, due to the unique disordered region at the ice surface known as the quasi-liquid layer (QLL) . The physical and chemical nature of the surfacial region of ice is greatly affected by solutes such as sodium halide salts. In this work, we studied the effects of sodium chloride and sodium bromide on the photolysis kinetics of harmine, an aromatic organic compound, in aqueous solution and at the surface of frozen salt solutions above the eutectic temperature. In common with other aromatic organic compounds we have studied, harmine photolysis is much faster on ice surfaces than in aqueous solution, but the presence of NaCl or NaBr – which does not affect photolysis kinetics in solution – reduces the photolysis rate on ice. The rate decreases monotonically with increasing salt concentration; at the concentrations found in seawater, harmine photolysis at the surface of frozen salt solutions proceeds at the same rate as in aqueous solution. These results suggest that the brine excluded to the surfaces of frozen salt solutions is a true aqueous solution, and so it may be possible to use aqueous-phase kinetics to predict photolysis rates at sea ice surfaces. This is in marked contrast to the result at the surface of frozen freshwater samples, where reaction kinetics are often not well-described by aqueous-phase processes.
