Kollektivierung der Phantasie?
Authors: Jacoby Petra
Published: May 2015

Kunst sollte im Staatssozialismus der DDR den Herrschaftsanspruch durch ästhetische Präsentation der beabsichtigten gesellschaftlichen Wirklichkeit vergegenwärtigen. Soziale Kollektivbildungen und der Austausch von Handlungsformen zwischen Künstler- und Arbeiterschaft dienten diesem Zweck. Die Mehrheit der Künstler hingegen wollte mit Mitteln der Kunst zu einer neuen Gemeinschaft gelangen und verstand das Wirken in Zusammenschlüssen als Multiplikator ihrer künstlerischen Auffassungen. Diese kunstsoziologische Untersuchung basiert auf Archivdokumenten und zeigt die gegenkulturellen Potenziale der Verbindung zwischen Leben und Kunst auf.
Die Bodenhaftung der Netzwerkgesellschaft
Authors: Potthast Jörg
Published: May 2015

Technische Pannen sind unvermeidbar, ihre Ursachen und Folgen oftmals unklar und umstritten. Die betroffenen Organisationen reagieren darauf mit zwei Strategien, die in einem komplizierten Verhältnis zueinander stehen: Ursachenforschung und Schuldzuweisung. Diese Problematik des Umgangs mit Pannen wird anhand von ethnografischen Studien zur Krise der Gepäckabfertigung an den Flughäfen Paris Roissy und London Heathrow analysiert. Es stellt sich heraus, dass die beiden Strategien unvereinbar sind und dennoch auf immer virtuosere Weise kombiniert werden. Dieser Befund stellt die These vom Aufstieg der Netzwerkgesellschaft in Frage.
Vom Nordatlantik zum »Black Atlantic«
Authors: Costa Sérgio
Published: May 2015

Im Ausgang von einer Untersuchung der Beziehungen zwischen antirassistischen Bewegungen in Brasilien und in den USA thematisiert dieser Band die Paradoxien einer transnationalen Politik von unten. Im Zentrum des Interesses stehen demokratietheoretische und soziologische Fragestellungen, die mit Hilfe dreier Theorieansätze diskutiert werden: Habermas' Ausführungen zur postnationalen Konstellation, die Theorie der reflexiven Moderne von Giddens und Beck sowie die soziologische Rezeption der Postcolonial Studies. Durch fundierte empirische Arbeit und präzise Theoriekritik arbeitet die Studie gegen den »Mainstream« eine konstruktiv dezentrierte soziologische Perspektive aus, in der sich die globale Gesellschaftsordnung jenseits epistemologischer Eurozentrismen zeigt. Das Buch schlägt damit eine Brücke zwischen den Diskursen der Cultural bzw. Postcolonial Studies auf der einen Seite und der Soziologie auf der anderen Seite.
Wolfsprojektionen: Wer säugt wen?
Authors: Mangelsdorf Marion
Published: May 2015

Wölfe überqueren Grenzen, ebenso die entlegener Alpenpässe wie die zu Großstädten nach Brasov, Rom oder Berlin. Ihre Spuren finden sich in den durch Ängste und sexuelle Fantasien hervorgerufenen Abgründen. Es sind dies Hybridzustände, die sowohl in mittelalterlichen, künstlerischen als auch cineastischen Projektionen in Szene gesetzt wurden. Dabei werden Ambivalenzen thematisiert - zu jenen Wilden, mit denen sich die Menschen gemeinsam weltweit ausbreiteten. In einem zeitgenössischen Prozess, in dem Körper zu Objekten von Forschungslaboren eines globalisierten Marktes generieren, provozieren solche Grenzgänger bedenkenswerte Irritationen. Das Buch unternimmt den spannenden Versuch, die Überlegungen von Donna Haraway zur Erweiterung des Mensch-Maschine-Komplexes zu einem Mensch-Maschine-Tier-Komplex am Beispiel des Wolfes durchzuspielen. Es erweitert damit die Infragestellung von eindeutigen Grenzziehungen des Natur-Kultur-Gegensatzes im Stile des »technoscience«-Paradigmas um eine bislang eher vernachlässigte Dimension, nämlich die des Tierischen.
Vom Nutzen der Poesie
Authors: Burbaum Christina
Published: May 2015

Welche alltagsweltliche Relevanz haben Gedichte für erwachsene Leserinnen und Leser? Im Mittelpunkt dieses Buches steht die Frage, wie Gedichte in der phänomenalen Welt von Menschen erscheinen und in sinnhafte Handlungen eingebettet sind. Auf der Basis von qualitativen Interviews werden folgende Themen gesprächsanalytisch bearbeitet: Wie gestalten Menschen im Umgang mit Gedichten soziale Beziehung? Wie nutzen sie das Medium zur Lebensbewältigung und zur Identitätsarbeit? Durch welche sprachlich-kommunikativen Phänomene zeichnet sich das Sprechen über Gedichte aus? Die explorative Studie zeigt den Facettenreichtum, die Komplexität und die vielfältigen Bedeutungshorizonte des Umgangs mit und des Sprechens über Gedichte.
Die Ökonomisierung der Gesellschaft
Authors: Krönig Franz Kasper
Published: May 2015

»Ökonomisierung« ist in aller Munde. Die systemtheoretische Perspektive auf das vermeintlich vertraute Phänomen stellt eine doppelte Herausforderung dar. Um Ökonomisierungsprozesse rekonstruieren zu können, muss die Systemtheorie ihre Möglichkeiten der Darstellung von System-System-Beziehungen erweitern und Ökonomisierung zu einem Paradoxieproblem werden lassen. Diese Studie liefert Impulse zur Theorieerweiterung im Bereich der Nebencodierung und zeigt an verschiedenen Beispielen, dass Ökonomisierung nicht wirtschaftlich instruiert, sondern funktionssystem-intern selbst ausgebildet wird.
Ein musikalisches Stück Heimat
Authors: Mendívil Julio
Published: May 2015

Dieses Buch beschäftigt sich mit dem deutschen Schlager als kulturellem Werkzeug für die Konstruktion eines Heimatgefühls in der aktuellen deutschen Gesellschaft. Sowohl theoretisch als auch methodisch orientiert sich der Autor dabei an einer postmodernen und reflexiven Musikethnologie sowie an der Tradition der Cultural Studies. Das Buch beschreibt seine ethnographischen Erfahrungen als nicht-westlicher Ethnologe in Deutschland. Das Resultat ist eine intensive - und manchmal ironische - wissenschaftliche Auseinandersetzung mit der Geschichte des Schlagers bzw. der Geschichte der wissenschaftlichen Beschäftigung mit dem Schlager.
Visuelle Autobiographien
Authors: Kittner Alma-Elisa
Published: May 2015

Die Faszinationskraft von Autobiographien ist ungebrochen; zugleich ergreift die Musealisierung des Selbst auch die bildende Kunst. Anhand der bisher kaum analysierten Werke »Lebensbild« von Hannah Höch, »Autobiographische Geschichten« von Sophie Calle und »Alben-Sammlungen« von Annette Messager widmet sich dieses Buch den folgenden Fragen: Was ist eine visuelle Autobiographie? Wie entwirft sich das Subjekt über Fotografien, Texte und Sammlungen von Objekten? Über die Einzelanalysen hinaus wird erstmals die Überschneidung von Autobiographie, Fotografie und Sammlung in den Blick genommen.
Bilder von Sexualität und Ökonomie
Authors: Engel Antke
Published: May 2015

Gibt es eine intime Beziehung zwischen sexueller Freiheit und Marktfreiheit? Bilder dissidenter Sexualität und geschlechtlicher Ambiguität finden sich heute nicht nur in sexueller Subkultur, sondern auch in kommerzieller Werbung. Die entstehenden Überlappungsfelder - queere Diskurse in kommerziellen ebenso wie neoliberale Diskurse in queeren visuellen Produkten - sind Schauplätze kultureller Politiken. Aus einer queeren Perspektive lotet dieser Band das Verhältnis von Sexualität und neoliberaler Ökonomie aus: Wie bedingen sie sich wechselseitig? Fordern sie sich gegenseitig heraus? Die Studie bietet zudem methodische Anregungen zum Einsatz kulturwissenschaftlicher Bildlektüren in sozialwissenschaftlicher Forschung.
Die sanfte Macht
Authors: Patzwaldt Katja
Published: May 2015

Das Thema Politikberatung hat wieder Konjunktur, seitdem die rot-grüne Regierung in bis dahin ungekannter Weise Wissenschaftler in die Vorbereitung von Reformen einbezog. In diesem Buch werden die entscheidungsrelevanten Beratungen für ein Politikfeld, die Arbeitsmarktpolitik, in Augenschein genommen. Es wird gezeigt, wie Wissenschaft und Politik sich in der Praxis miteinander verbinden und wie diese Beziehung sich entwickelt hat. Ein organisationstheoretisches Erklärungsmodell bezieht die Bedeutung eines Beratergremiums für die Regierung und ihre Politik auf ihre Leistungsfähigkeit als Organisation. Mit der Betrachtung politischer Erwartungen und organisatorischer Prozesse betritt die Autorin wissenschaftliches Neuland und gibt zugleich praktische Hinweise für zukünftige Politikberatungen.
Interkulturelles Theater zu Beginn des 21. Jahrhunderts
Authors: Regus Christine
Published: May 2015

Das Theater ist seit jeher von interkulturellem Austausch geprägt. Besonders die Avantgarden des 20. Jahrhunderts verdeutlichen, dass die Begegnung mit dem kulturell Andersartigen immer wieder zu radikal neuen Ästhetiken geführt hat. Theater ist aber nicht bloß eine Kunstform: Es hat stets auch eine politische Dimension. Umso mehr erstaunt es, dass die Wissenschaft über Jahre interkulturelles Theater kaum beachtet hat - trotz der Diskussionen interkultureller Probleme im Zeitalter der Globalisierung. Hier eröffnet sich ein Feld für kultur- und theaterwissenschaftliche Reflexion, das neuer Ansätze bedarf - vor allem für das Verhältnis von Ästhetischem und Politischem. Während das Politische oft in den Stoffen einer Aufführung gesehen wird, weist dieses Buch nach, dass das Ästhetische im interkulturellen Theater immer zugleich das Politische ist. Es beschreibt aktuelle Formen der Verflechtung differenter Theaterkulturen aus Asien, Süd- und Nordamerika und entwickelt dabei die theoretischen Grundzüge einer postkolonialen Ästhetik interkulturellen Theaters.
Imagination im Erkenntnisprozess
Authors: Wettig Sabine
Published: May 2015

»Geistesgegenwart. Das ist der aktuelle Name für Phantasie.« (Dietmar Kamper) Diese kulturwissenschaftliche Studie zeigt, dass die Bilderflut des Medienzeitalters mit ihrer mittlerweile offensichtlichen »Immanenz des Imaginären« heute ihre Bauprinzipien preisgibt. Diese zu entziffern sind wir aufgerufen: Wenn wir verstehen, wie es den Bildern gelungen ist, Macht über uns zu gewinnen, werden wir die sie hervorbringende Imagination neu entdecken und als menschliche und kognitive Ressource erfahren. Das bewegte, technische Bild als Bestandteil unserer Alltagskultur, der Kultur eines audiovisuellen Zeitalters, kann insofern als sichtbare Aufforderung zu einer grundlegenden Imaginationsforschung aufgefasst werden.
Projizierte Kunstgeschichte
Authors: Berger Doris
Published: May 2015

Künstlergenies entfalten eine facettenreiche Strahlkraft - besonders auf der Filmleinwand. Sie wirken auf unsere Vorstellungen vom Künstlerdasein und von künstlerischer Produktion. Der Fokus der »projizierten Kunstgeschichte« liegt auf biografischen Spielfilmen (Biopics), in denen die Lebensgeschichten von Künstlerinnen und Künstlern auf dramatisierende Weise inszeniert und von Schauspielstars verkörpert werden. Anhand der Biopics »Pollock« (2000) und »Basquiat« (1996) untersucht dieses Buch aus kunsthistorischer und filmwissenschaftlicher Sicht die Künstler_innenmythen und Starlegenden, die textlichen und visuellen Vorlagen und ihre Repräsentationspolitik. Künstlergenie ade - oder: es lebe das Künstlergenie?
Globalisierte Nahrungskrisen
Authors: Gertel Jörg
Published: May 2015

Ernteausfälle in der Ukraine, spekulative Preissteigerungen am »Chicago Board of Trade« sowie die Milliardendollarumsätze von Getreidehändlern wie Cargill kombinieren sich mit wachsender Armut und prägen die Nahrungsunsicherheit. Selbst wenn in Kairo die Krisenursachen verborgen bleiben, ist eines klar: »Aish« - das ägyptische Synonym für Brot und Leben - wird immer teurer. Das Buch zeigt, wie im globalen Agro-Food-System Kairo zur Bruchzone neoliberaler Deregulation wird, und argumentiert, dass durch die Nahrungsmittel-Proteste 2008 bisher nur die Spitze globalisierter Nahrungskrisen sichtbar geworden ist.
Krieg mit Metaphern
Authors: Kirchhoff Susanne
Published: May 2015

Kriege werden in demokratischen Gesellschaften im öffentlichen Diskurs legitimiert oder delegitimiert. Metaphern tragen dazu bei, indem sie Deutungsrahmen bereitstellen, mit denen sich die Ereignisse verstehen, bewerten und in den eigenen Erfahrungshorizont einordnen lassen. Susanne Kirchhoff zeigt anhand der Berichterstattung deutscher Nachrichtenmagazine über 9/11 und die nachfolgenden Kriege, wie mit Hilfe von Metaphern eine eigene Identität in Abgrenzung von den USA und der arabisch-islamischen Welt konstruiert wurde. Zudem erlaubt die materialreiche Studie eine Auseinandersetzung mit dem Wert der kognitiven Metaphernanalyse für die Medien- und Kommunikationswissenschaft.

Published: May 2015

To date, the hemoglobin (Hb) typing control materials for laboratory investigation of thalassemia with low (1.8%–3.2%) and high (4%–6%) levels of HbA

Erythrocytes of blood samples containing Hb Bart’s, HbH, HbE, HbF, Hb Constant Spring (CS), Hb Hope, and Hb Q-Thailand were washed and dialysed with 0.85% saline solution. The erythrocytes were then lysed in 5% sucrose solution. The lyophilized Hb typing control materials were prepared by using a freeze drying (lyophilization) method. The high performance liquid chromatography (HPLC) analysis of lyophilized Hb was performed after the storage at −20 °C for 1 year and also after reconstitution and storage at 4 or −20 °C for 30 days. In addition, the Hb analysis was compared between the three different methods of HPLC, low pressure liquid chromatography (LPLC) and capillary electrophoresis (CE).

Following a year of storage at −20 °C, the HPLC chromatograms of lyophilized Hb typing control materials showed similar patterns to the equivalent fresh whole blood. The stability of reconstituted Hb typing control materials was also observed through 30 days after reconstitution and storage at −20 °C. Moreover, the Hb typing control materials could be analyzed by three methods, HPLC, LPLC and CE. Even a degraded peak of HbCS was found on CE electropherogram.

The lyophilized Hb typing control materials could be developed and used as control materials for investigation of thalassemia and hemoglobinopathies.
A photovoltaic stand-alone lighting system with polymeric-silica-gel-electrolyte-based substrate-integrated lead-carbon hybrid ultracapacitors
Authors: Banerjee A. , Ramasesha S. K. , Shukla A. K.
Published: May 2015

Harnessing solar electricity generated through photovoltaic cells with lead-acid batteries remains the most compelling option at present. But lead-acid batteries have encountered problems in photovoltaic installations, mainly due to their premature failure. To circumvent the aforesaid problem, a new technology referred to as substrate-integrated lead-carbon hybrid ultracapacitor with polymeric-silica-gel electrolyte, is developed inhouse and tested for solar-electricity storage for a lighting application. The high-throughput performance tests for the device are conducted at laboratory scale and compatibility of the device for photovoltaic application is evaluated. In doing so, the device is installed with a photovoltaic panel for field test and data are collected from August 2012 through July 2013. The year round field-test data analyzed in the light of the available global-horizontalirradiance data show attractive performance for the device. It is noteworthy that, unlike lead-acid batteries, seasonal variations in solar radiance exhibit little effect on the performance of the device.
Crystal Structures and Properties of Pb(Ni1/3,Nb2/3)O3–Pb(Zr1/2,Ti1/2)O3 Thin Films on Silicon Substrates
Authors: Ren Xue-Ting , Yang Ying , Wang Yi-Ping , Nie Peng-Xiao
Published: May 2015

Pb(Zr,Ti)O3 (PZT)-based ternary system thin films, xPb(Ni,Nb)O3–(1–x)PZT (50/50) (PNN–PZT), are grown on Pt/TiO2/SiO2/Si substrates using radio-frequency magnetron sputtering system. The intrinsic PZT (50/50) thin films are also deposited for comparison. XRD data display a perovskite structure in PNN–PZT thin films, which is similar with that of PZT films. On the other hand, the adding of PNN induces a change in the ratio of (200)/(002) peak intensity in the diffraction patterns, and the tetragonality of PNN–PZT thin films decreases with increasing x. The morphotropic phase boundary (MPB) of PNN–PZT thin film system is confirmed near the composition of 0.05PNN–0.95PZT. PNN–PZT thin films exhibit excellent piezoelectricity and ferroelectricity which are distinctly better than those of PZT thin films. In particular, very high remanent polarization, P
r=99 μC/cm2, small coercive field of 55 kV/cm, large relative dielectric constants, ε
r=2,030 and distinct piezoelectric response are observed from sample 0.05PNN–0.95PZT.
Evaluation of the Ecosystem Services of Inland Waters in the Slovak Republic - To Date Findings
Authors: Bujnovský Radoslav
Published: May 2015

Ecosystem services (ES) (goods and services) represent the outputs of natural systems from which people can have benefits. Evaluation of the benefits resulting from ES of inland waters or the benefits, which are lost when the necessary measures are not implemented, is one of the methods of evaluating the external costs of environmental damage - environmental and resource costs. Evaluation of ES is based on the CICES classification v. 4.3, which defines provision, regulation/ maintenance and cultural services. In the assessment of ES also enters groundwater, although in comparison with surface waters in lesser extent. At present, the evaluation is performed at the level of sub-basins of the Slovak Republic. In this paper, evaluation of selected ES is presented. Use of evaluation in practice is also discussed.
Carbon Storage in Beech Stands on the Chřiby Uplands
Authors: Schneider Jiří , Holušová Kateřina , Rychtář Jan , Vyskot Ilja , Lampartová Ivana
Published: May 2015

The submitted scientific statement is a contribution to solutions of monitoring the storage of carbon in the woods and its emissions. Four permanent research plots were established in the area of the Chřiby uplands in the Czech Republic. The plots are made of forest stands with nearly 100% of European beech (Fagus sylvatica L.). The stands form simple spatial structures of about the same age (about 180 years). They represent, however, varying site conditions (dwarf acid beech stands, herb-rich beech stands and transitions between them). For quantification of carbon storage, standard dendrometric methods and the Field-Map technology were used. The total amount of carbon was established as the sum of further documented carbon storages in the aboveground biomass, the belowground biomass, woody debris and the forest soil. Determination of total amount of carbon was addressed in a version manner. In the first version, the estimate of the total amount of carbon was established based on Wutzler et al. (2008) equations for the aboveground biomass (AGB) and the belowground biomass (BB). In the second version, the AGB was calculated according to Joosten et al. (2004), the BB according to Wirth et al. (2003), the values of storages were consistent with Mund (2004) for woody debris, and with Mackù in Kolektiv (2007) for forest soil. Total carbon storage per hectare of stand is in average 370.2 t. Obtained outcomes support the quantitative results of latest research related to carbon in the woods.
High β-glucosidase (GBA) activity not attributable to GBA1 and GBA2 in live normal and enzyme-deficient fibroblasts may emphasise the role of additional GBAs
Authors: Harzer Klaus , Yildiz Yildiz
Published: May 2015

Beta-glucosidases (GBA) include GBA1, GBA2 and other β-glucosidases (non-GBA1-2). GBA1 is a lysosomal and GBA2 an extra-lysosomal enzyme. GBA1- and GBA2-deficient genetic conditions, with different phenotypes, are glucosylceramide (GC; the main GBA substrate) accumulating diseases. To study the activity profile of GBA, live fibroblasts were loaded with radioactive GC. The GC metabolism was measured in wild-type, GBA1-deficient (Gaucher disease) and GBA2-deficient (Gba2-/- mouse) cells. The differences found allowed the prediction of marked proportions of GBA1, GBA2, and particularly non-GBA1-2 (probably including GBA3, a cytosolic β-glucosidase) activity for wild-type cells. The high proportion of non-GBA1-2 suggests an important role of these enzymes.

Authors: Alehosseini Ali , A. Hejazi Maryam , Mokhtari Ghassem , B. Gharehpetian Gevork , Mohammadi Mohammad
Published: May 2015

In this paper, the Bayesian classifier is used to detect and classify the radial deformation and axial displacement of transformer windings. The proposed method is tested on a model of transformer for different volumes of radial deformation and axial displacement. In this method, ultra-wideband (UWB) signal is sent to the simplified model of the transformer winding. The received signal from the winding model is recorded and used for training and testing of Bayesian classifier in different axial displacement and radial deformation states of the winding. It is shown that the proposed method has a good accuracy to detect and classify the axial displacement and radial deformation of the winding.

Authors: Voronin Anatoly F.
Published: May 2015

In this paper, a Volterra integral equation of the first kind in convolutions on the semiaxis when the integral operator kernel and the right-hand side of the equation have a
bounded support is considered. An inverse problem of reconstructing the solution to the equation and the integral operator kernel from values of the right-hand side is formulated.
Necessary and sufficient conditions for the inverse problem solvability are obtained. A uniqueness and stability theorem is proved. Explicit formulas for reconstruction of the solution and kernel are obtained.
Nuclear norm and indicator function model for matrix completion
Authors: Geng Juan , Wang Laisheng , Wang Xiuyu
Published: May 2015

In the matrix completion problem, most
methods to solve the nuclear norm model are relaxing it
to the nuclear norm regularized least squares problem.
In this paper, we propose a new unconstraint model for
matrix completion problem based on nuclear norm and indicator function
and design a proximal point algorithm (PPA-IF) to solve it.
Then the convergence of our algorithm is established strictly.
Finally, we report numerical results for solving noiseless and
noisy matrix completion problems and image reconstruction.
Calibrating the model parameters in pricing using the trust region method
Authors: Xu Zuo-liang , Ma Qing-hua , Wang Li-ping
Published: May 2015

In this paper, we aim to calibration pricing models from market prices. We investigate the problem of calibrating the parameters using the trust region method from given price data. We start with the Hull–White model and formulate the problem by obtaining the first kind integral equation, and then consider the parameter recovery problem of the Black–Scholes model. We apply trust region algorithm for numerical retrieval problems.
Numerical simulations are given to illustrate the feasibility of our proposed method.
An optimal filtering method for a time-fractional inverse advection-dispersion problem
Authors: Zhao Jingjun , Liu Songshu
Published: May 2015

We consider an inverse problem for a time-fractional advection-dispersion equation, where the measured data is given at x = 1 and the solution is sought in the interval 0 ≤ x < 1. Such a problem is obtained from the classical advection-dispersion equation by replacing the first-order time derivative by the Caputo fractional derivative of order α ∈ (0,1). We show that the inverse problem for a time-fractional advection-dispersion equation is severely ill-posed and we further apply an optimal filtering regularization method to solve it, based on the solution in the frequency domain. The corresponding convergence estimates are provided. To illustrate the results, an example is constructed to show the feasibility and efficiency of the proposed method.
Simultaneous determination of thickness, thermal conductivity and porosity in textile material design
Authors: Xu Dinghua , Cui Peng
Published: May 2015

The thickness, thermal conductivity and porosity of textile material are three key factors
which determine the heat-moisture comfort level of the human body to a large extent
based on the heat and moisture transfer process in the human body-clothing-environment system.
This paper puts forward an Inverse Problem of Textile Thickness-Heat conductivity-Porosity Determination (IPT(THP)D)
based on the steady-state model of heat and moisture transfer
and the heat-moisture comfort indexes. Adopting the idea of the weighted least-squares method,
we formulate IPT(THP)D into a function minimization problem.
We employ the Particle Swarm Optimization (PSO) method to stochastically search the optimal solution of the objective function.
We put the optimal solution into the corresponding direct problem to verify the effectiveness of the
proposed numerical algorithms and the validity of the IPT(THP)D.
Reconstruction of prograde and retrograde Chandler excitation
Authors: Zotov Leonid V. , Bizouard Christian
Published: May 2015

Observed polar motion consists of uniform circular motions at both positive (prograde) and negative (retrograde) frequencies. Generalized Euler–Liouville equations of Bizouard, taking into account Earth's triaxiality and asymmetry of the ocean tide, show that the corresponding retrograde and prograde circular excitations are coupled at any frequency. In this work, we reconstructed the polar motion excitation in the Chandler band (prograde and retrograde). Then we compared it with geophysical excitation, filtered out in the same way from the series of the Oceanic Angular Momentum (OAM) and Atmospheric Angular Momentum (AAM) for the period 1960–2000. The agreement was found to be better in the prograde band than in the retrograde one.
Generalized sensitivity functions for size-structured population models
Authors: Keck Dustin D. , Bortz David M.
Published: May 2015

Size-structured population models provide a popular means to mathematically
describe phenomena such as bacterial aggregation, schooling fish,
and planetesimal evolution. For parameter estimation, a generalized
sensitivity function (GSF) provides a tool that quantifies the impact
of data from specific regions of the experimental domain. This function
helps to identify the most relevant data subdomains, which enhances
the optimization of experimental design. To our knowledge, GSFs have
not been used in the partial differential equation (PDE) realm, so
we provide a novel PDE extension of the discrete and continuous ordinary
differential equation (ODE) concepts of Thomaseth and Cobelli and
Banks et al. respectively. We analyze a GSF in the context of size-structured
population models, and specifically analyze the Smoluchowski coagulation
equation to determine the most relevant time and volume domains for
three, distinct aggregation kernels. Finally, we provide evidence
that parameter estimation for the Smoluchowski coagulation equation
does not require post-gelation data.

Our variant improves the computational complexity at the cost of a moderate increase in memory consumption, but we also improve the computational complexity
even when we limit the memory usage to that of Diem's original algorithm. Finally, we examine how parallelization can help to reduce both the memory cost per computer and the running time for our algorithms.

Amplitude and phase synchronization of European business cycles: a wavelet approach
Authors: Bruzda Joanna
Published: May 2015

In the paper we suggest the use of amplitude correlation coefficients (ACCs) and phase-locking values (PLVs) in examining business cycle synchronization. The quantities are calculated on the basis of instantaneous amplitudes and phase differences, which are computed here with the help of the non-decimated discrete analytic wavelet transform. We show that the coefficients constitute an interesting add-in to the statistical apparatus of examining business cycle synchronization. The PLVs correct the information provided by the coherency and correlation coefficients for the influence of amplitude changes and are of use in examining phase synchronization of business cycles, which is important in forecasting the effectiveness of a common monetary policy. By contrast, the ACCs are based solely on amplitude information and have the interpretation of phase-adjusted correlation coefficients, which can be used to evaluate stabilization policies or to forecast these policies’ effectiveness. The methodology is applied to examine cyclical synchronization of 20 European Union (EU) countries. We show, among other things, that during the run-up to the euro both amplitude and phase synchronization increased, with the former tending to change more rapidly. Furthermore, for the new EU members an EU effect is identified in both types of cyclical synchronization with the euro area.

According to the studies, the local axial distortion angle Δα (≈ 5.1°) and the planar bond angle θ (≈ 83.8°) in [CuO6]10- cluster was obtained. The theoretical EPR parameters based on the aforementioned local structure parameters show good agreement with the observed values, and some improvement have been made as compared with the previous studies.
Characterization of Na and Ca Zeolites Synthesized by Various Hydrothermal Treatments of Fly Ash
Authors: Koshy Nevin , Singh D. N. , Jha Bhagwanjee , Kadali Srinivas , Patil Jayant
Published: May 2015

For the past several decades, researchers have studied the zeolitization of coal fly ash (class-F) by following different methods (viz., open and closed hydrothermal, and fusion followed by hydrothermal). In fact, these methods involve sequential processes like (i) dissolution of silica and alumina from the fly ash, (ii) nucleation of zeolite, and (iii) crystallization (growth of zeolite) in the reactant solution. Also, performance of these processes has been reported to vary with the type of alkali used as reactant and often, NaOH has been preferred for high cation exchange capacity, resulting in sodium zeolites. However, large scale applications of Na-based zeolites in soil and water are questionable due to the presence of high sodium, thereby increasing the sodicity and salinity of the soil/water. In addition, performance of the zeolites, as adsorbent, synthesized by different methods is expected to depend on various characteristics (viz., mineralogy, structural bonding, specific surface area, pore volume, and morphology), of the zeolites. In order to address the above issues, the present study is focused to investigate the various characteristics of the synthesized zeolites by (i) the above mentioned three methods, (ii) using Ca(OH)2 as reactant, and (iii) considering Na and Ca present in the fly ash. Thus, the aim of the study was to ascertain (i) a suitable method out of the three and (ii) characteristics of the blend of Na- and Ca-zeolites from the fly ash, which can be used as a controlled release fertilizer, as sorbent for water and soil decontamination.

List of Fluorescent Whitening Agents for the Soap and Detergent Industry
Authors:   ASTM Committee D12
Published: May 2015

Description

By far, the largest single consumer of Fluorescent Whitening Agents (FWAs) is the soap and detergent industry. In the past, the identification of these products in test methods, publications, customs declarations, etc. has been primarily limited to individual supplier's trade names which often create confusion and ambiguity. Although several of the products are included in the Colour Index, this compilation is incomplete and, in some instances, inaccurate.

Design of a Pseudo-Interval Autonomous SCPT System
Authors: Baziw Erick , Verbeek Gerald
Published: May 2015

Seismic cone penetration testing (SCPT) is a geotechnical tool which allows for the determination of low strain (<10−4%) in situ compression (VP) and shear (VS) wave velocities. Among in situ engineers, there is considerable interest in the development and advancement of SCPT systems, which operate autonomously without any user interaction aside from initial start-up. This technical note outlined such a system (a pseudo-interval autonomous SCPT system), and covered in detail the autonomous sensor based data triggering algorithm, which is an essential element of an autonomous system that can be used both onshore as well as offshore.

Published: May 2015

This report presents the results obtained from an experimental study of the accuracy and precision of measurements of particulate and vaporous lead using a colorimetric dithizone procedure as described in ASTM Method D-3112. Measurements of lead concentration in spiked and unspiked atmospheric air samples were performed by eight participating laboratories at three test sites: Los Angeles, California; Bloomington, Indiana; and New York, New York. The first series of field tests were conducted at the University of Southern California on August 15–21, 1971; the second series of field tests were conducted at Indiana University on October 24–30, 1971; and the third series of field tests were conducted at Cooper Union (New York City), on January 9–15, 1972. All measurements were made according to a tentative ASTM method for lead in the atmosphere from which ASTM Method D 3112 evolved.

Published: May 2015

In 1971 in recognition of the important relationship between the measurement and the effective control of air pollution, Committee D-22 of American Society for Testing and Materials (ASTM) initiated a pioneering program, designated Project Threshold, to validate methods for measuring contaminants in the ambient atmosphere and in emissions from individual sources. The first phase of the program was devoted to evaluation of methods for measuring the content of nitrogen dioxide (D 1607-69), sulfur dioxide (D 2914-70T), dustfall (D 1739-70), total sulfation (D 2010-65), particulate matter (D 1704-61), and lead (D 3112) in the atmosphere (1-6).

Objective

Although it has been recommended that serum free thyroxine (FT4) levels should be targeted to middle-upper normal levels during levothyroxine (l-T4) replacement therapy in patients with central hypothyroidism (CeH), the rationale has not been clarified.

Methods

A retrospective single-center study enrolled 116 patients with hypothyroidism (CeH,n=32; total thyroidectomy (Tx),n=22; primary hypothyroidism (PH),n=33; and control benign thyroid nodule (C),n=29). The patients had receivedl-T4therapy at the Kobe University Hospital between 2003 and 2013. They were stratified according to serum FT4level (≥1.10 or <1.10 ng/dl), and body temperature (BT), serum free triiodothyronine (FT3) levels, FT3/FT4ratio, and lipid profiles were compared. The effect of GH replacement therapy on thyroid function was also analyzed.

Results

FT3levels and FT3/FT4ratios were significantly lower in patients with CeH than in patients with PH (P<0.05) or C (P<0.05). In patients with FT4<1.10 ng/dl, BT was significantly lower in patients with CeH (P=0.002) and Tx (P=0.005) than in patients with PH, whereas no differences were found in patients with FT4≥1.10 ng/dl. In patients with CeH, FT3levels were higher in those with GH replacement therapy (P=0.018).

Conclusion

In CeH, patients with median-lower normal levels of serum FT4exhibited lower serum FT3levels and lower BT. These results support the target levels of serum FT4as middle-upper normal levels duringl-T4replacement therapy in patients with CeH.

Malnutrition in the elderly is accompanied by several metabolic dysfunctions, especially alterations in energy homeostasis regulation and a loss of insulin responsiveness. Nutritional recommendations aim to enrich food with high protein and energy supplements, and protein composition and lipid quality have been widely studied. Despite the numerous studies that have examined attempts to overcome malnutrition in the elderly through such nutritional supplementation, it is still necessary to study the effects of a combination of protein, lipids, and vitamin D (VitD). This can be done in animal models of elderly malnutrition. In the present study, we investigated the effects of several diet formulae on insulin responsiveness, inflammation, and the hypothalamic expression of key genes that are involved in energy homeostasis control. To mimic elderly malnutrition in humans, elderly Wistar rats were food restricted (R, −50%) for 12 weeks and then refed for 4 weeks with one of four different isocaloric diets: a control diet; a diet where milk soluble protein (MSP) replaced casein; a blend of milk fat, rapeseed, and DHA (MRD); or a full formula (FF) diet that combined MSP and a blend of MRD (FF). All of the refeeding diets contained VitD. We concluded that: i) food restriction led to the upregulation of insulin receptor in liver and adipose tissue accompanied by increasedTnfαin the hypothalamus; ii) in all of the refed groups, refeeding led to similar body weight gain during the refeeding period; and iii) refeeding with MSP and MRD diets induced higher food intake on the fourth week of refeeding, and this increase was associated with reduced hypothalamic interleukin 6 expression.
Mitochondrial biogenesis and degradation are induced by CCCP treatment of porcine oocytes

In this study, we investigated the mitochondrial quality control system in porcine oocytes during meiotic maturation. Cumulus cell oocyte complexes (COCs) collected from gilt ovaries were treated with 10 μM carbonyl cyanide-m-chlorophenylhydrazone (CCCP; a mitochondrial uncoupler) for 2 h. The CCCP treatment was found to significantly reduce ATP content, increase the amount of phosphorylated AMP-activated protein kinase and elevate reactive oxygen species levels in oocytes. When the CCCP-treated COCs were cultured further for 44 h in maturation medium, the ATP levels were restored and the parthenogenetic developmental rate of oocytes to the blastocyst stage was comparable with that of untreated COCs. To examine the effects of CCCP treatment of oocytes on the kinetics of mitochondrial DNA copy number (Mt number), COCs treated with 0 or 10 μM CCCP were cultured for 44 h, after which the Mt number was determined by RT-PCR. CCCP treatment was found to increase the Mt number in the modified maturation medium in which mitochondrial degradation was inhibited by MG132, whereas CCCP treatment did not affect the Mt number in the maturation medium lacking MG132. The relative gene expression of TFAM was furthermore shown to be significantly higher in CCCP-treated oocytes than in untreated oocytes. Taken together, the finding presented here suggest that when the mitochondria are injured, mitochondrial biogenesis and degradation are induced, and that these processes may contribute to the recuperation of oocytes.
Versenyző fiatalok versengés, győzelem és vesztés fogalmának vizsgálata az Asszociatív Csoportanalízis Technika segítségével

Bár korábbi vizsgálatok alapján feltételezhetjük, hogy a tehetséges személyek pozitívabban viszonyulnak, és konstruktívabb megküzdést alkalmaznak versengő helyzetekben, mint átlagos társaik (FÜlÖp, 1992; PinczÉs-Pressing és FÜlÖp, 2013), tudomásunk szerint jelenleg nem áll rendelkezésünkre eredmény azzal kapcsolatban, hogy a hasonlóan jó képességű, ám eltérő eredményeket felmutató személyek között van-e különbség abban, ahogy a versengésről, a győzelemről és a vesztésről gondolkodnak. Ezért egy nagyobb vizsgálatsorozat részeként online asszociációs vizsgálatot végeztünk az Asszociatív Csoportanalízis Technika segítségével (Szalay és Brent, 1967) egy 400 fős életkor és nem szerint is illesztett minta bevonásával (átlagéletkor: 17,96 év), amelyben 200 eredményes, illetve 200 nem eredményes versenyző szerepelt. Az alkalmazott hívószavak a versengés, a győzelem és a vesztés voltak. Eredményeink szerint az eredményes csoport komplexebb és pozitívabb módon viszonyul a vizsgált fogalmakhoz. Az ő asszociációikban nagyobb hangsúlyt kap a versengés motivációs aspektusa, illetve a pozitív érzelmek. Esetükben a versengésre és a győzelemre adott asszociációk az eredményre és a folyamatra egyaránt fókuszálnak, szemben a nem eredményes versenyzők inkább eredményorientált gondolkodásmódjával. Az eredményes versenyzők a vesztést inkább képesek lehetőségként értelmezni, és számos megküzdési módot kapcsolnak hozzá, míg a nem eredményes csoportra a vesztéssel kapcsolatos kevésbé elaborált megközelítés jellemző.
