description: The results are reported of the study of materials used in the CERN Closed Loop recirculation gas system currently under test with the RPC muon detectors in the CMS experiment at the LHC.  Studies include a sampling campaign in a low-radiation  environment (cosmic rays at the CERN ISR test site).  We describe the dedicated RPC chamber tests, the chemical analysis of the filters and gas used, and discuss the results of the Closed Loop system.
Detailed Field Distribution in CMS Winding
Creators: name: S. Farinon
name: P. Fabbricatore
Publisher: name: INFN Open Access Repository
Year: 2000

description: The CMS winding has now arrived at its constructive phase. This means that some practical aspects regarding the winding itself have to be considered, such as the minimum requirement of conductor performance for each layer of each module. Several magnetic calculations have been already performed, but the winding has been never analyzed in detail, in order to understand the impact of the self-field on its performances. This analysis and its implications are reported in this paper.

description: We report the successful fabrication of planar V/Cu/V mesoscopic Josephson weak-links of different size, and the analysis of their low-temperature behavior. The shorter junctions exhibit critical currents of several tens of microA at 350 mK, while Josephson coupling persists up to ~2.7 K. Good agreement is obtained by comparing the measured switching currents to a model which holds in the diffusive regime. Our results demonstrate that V is an excellent candidate for the implementation of superconducting nanodevices operating at a few kelvins.

Origin of power laws for reactions at metal surfaces mediated by hot electrons

description: A wide range of experiments have established that certain chemical reactions at metal surfaces can be driven by multiple hot electron mediated excitations of adsorbates. A high transient density of hot electrons is obtained by means of femtosecond laser pulses and a characteristic feature of such experiments is the emergence of a power law dependence of the reaction yield on the laser fluence $Y\sim F^n$. We propose a model of multiple inelastic scattering by hot electrons, which reproduces this power law and the experimentally found exponents of several experiments. All parameters are calculated within Density Functional Theory and the Delta Self-Consistent Field method. With a simplified assumption, the power law becomes exact and we obtain a simple and very useful physical interpretation of the exponent $n$, which represents the number of adsorbate vibrational states participating in the reaction.
How to increase the applicability of integral transform approaches in physics?

description: Integral transform approaches are numerous in many fields of physics, but in most cases limited to the use of the Laplace kernel. However, it is well known that the inversion of the Laplace transform is very problematic, so that the function related to the physical observable is in most cases unaccessible. The great advantage of kernels of bell-shaped form has been demonstrated in few-body nuclear systems. In fact the use of the Lorentz kernel has allowed to overcome the stumbling block of the ab initio description of reactions to the full continuum of systems of more than three particles. The problem of finding kernels of similar form, applicable to many-body problems deserves particular attention. If this search were successful the integral transform approach might represent the only viable ab initio access to many observables that are not calculable directly.

Expected high energy emission from GRB 080319B and origins of the GeV emission of GRBs 080514B, 080916C and 081024B

description: We calculate the high energy (sub-GeV to TeV) prompt and afterglow emission of GRB 080319B that was distinguished by a naked-eye optical flash and by an unusual strong early X-ray afterglow. There are three possible sources for high energy emission: the prompt optical and $γ$-ray photons IC scattered by the accelerated electrons, the prompt photons IC scattered by the early external reverse-forward shock electrons, and the higher band of the synchrotron and the synchrotron self-Compton emission of the external shock. There should have been in total {hundreds} high energy photons detectable for the Large Area Telescope (LAT) onboard the Fermi satellite, and {tens} photons of those with energy $> 10$ GeV. The $> 10$ GeV emission had a duration about twice that of the soft $γ$-rays. AGILE could have observed these energetic signals if it was not occulted by the Earth at that moment. The physical origins of the high energy emission detected in GRB 080514B, GRB 080916C and GRB 081024B are also discussed. These observations seem to be consistent with the current high energy emission models.

description: Ego identity and intimacy statuses were determined for 88 college students, 44 men, and 44 women, and related to each other and to measures of intimacy-isolation, loving and liking, Sex differences were also investigated. Identity achievement subjects were more likely to be engaged in intimate relationships. Students having foreclosure. moratorium. and diffusion identities were variable in their intimacy statuses. A stronger association exists between intimacy and loving than intimacy and liking. While no significant sex differences were found on the overall ego identity and intimacy comparisons, sub scale differences were noted. The evidence suggests identity achievement status is predictive of highly intimate relations while foreclosure, moratorium and diffusion identities are highly variable.

description: This paper presents a novel approach to network coding for distribution of large files. Instead of the usual approach of splitting packets into disjoint classes (also known as generations) we propose the use of overlapping classes. The overlapping allows the decoder to alternate between Gaussian elimination and back substitution, simultaneously boosting the performance and reducing the decoding complexity. Our approach can be seen as a combination of fountain coding and network coding. Simulation results are presented that demonstrate the promise of our approach.

description: The breaking of time-reversal symmetry in a triplet superconductor Josephson junction is shown to cause a magnetic instability of the tunneling barrier. Using a Ginzburg-Landau analysis of the free energy, we predict that this novel functional behaviour reflects the formation of an exotic Josephson state, distinguished by the existence of fractional flux quanta at the barrier. The crucial role of the orbital pairing state is demonstrated by studying complementary microscopic models of the junction. Signatures of the magnetic instability are found in the critical current of the junction.

Für den Fremdsprachenunterricht erweist sich dies in dem Sinne als eine neue Herausforderung, als die traditionellen Sprachlernleistungen Hören, Sprechen, Lesen, Schreiben (und Übersetzen) um einen kulturellen Aspekt erweitert werden müssen, damit die Lernenden auf die gesellschaftliche Wirklichkeit außerhalb des Unterrichts vorbereitet werden. In diesem Zusammenhang steht der vorliegende Band, der sich in neun Kapiteln mit dem schwierigen und komplexen Thema der interkulturellen Kommunikation befasst. Darauf wird bereits im Vorwort der Monographie hingewiesen.

description: The inner 10 pc of our galaxy contains many counterpart candidates of the very high energy (VHE; > 100 GeV) gamma-ray point source HESS J1745-290. Within the point spread function of the H.E.S.S. measurement, at least three objects are capable of accelerating particles to very high energies and beyond, and of providing the observed gamma-ray flux. Previous attempts to address this source confusion were hampered by the fact that the projected distances between those objects were of the order of the error circle radius of the emission centroid (34", dominated by the pointing uncertainty of the H.E.S.S. instrument). Here we present H.E.S.S. data of the Galactic Centre region, recorded with an improved control of the instrument pointing compared to H.E.S.S. standard pointing procedures. Stars observed during gamma-ray observations by optical guiding cameras mounted on each H.E.S.S. telescope are used for off-line pointing calibration, thereby decreasing the systematic pointing uncertainties from 20" to 6" per axis. The position of HESS J1745-290 is obtained by fitting a multi-Gaussian profile to the background-subtracted gamma-ray count map. A spatial comparison of the best-fit position of HESS J1745-290 with the position and morphology of candidate counterparts is performed. The position is, within a total error circle radius of 13", coincident with the position of the supermassive black hole Sgr A* and the recently discovered pulsar wind nebula candidate G359.95-0.04. It is significantly displaced from the centroid of the supernova remnant Sgr A East, excluding this object with high probability as the dominant source of the VHE gamma-ray emission.

description: A brief overview of the superconducting energy gap studies on 122-type family of iron pnictides is given. It seems that the situation in the hole-doped Ba1-xKxFe2As2 is well resolved. Most of the measurements including the presented here point-contact Andreev reflection spectra agree on existence of multiple nodeless gaps in the excitation spectrum of this multiband system. The gaps have basically two sizes - the small one with a strength up to the BCS weak coupling limit and the large one with a very strong coupling with 2Delta/kTc ~ 6 - 8. In the electron doped Ba(Fe1-xCox)2As2 the most of the experiments including our point contact measurements reveal in quite broadened spectra only a single gap with a strong coupling strength. The high precision ARPES measurements on this system identified two gaps but very close to each other, both showing a strong coupling with 2Delta/kTc ~ 5 and 6, respectively.

title: Participation in Family Decision Making by Korean Home Managers
Creators: name: Hwang, Hyo-Sook
Publisher: name: Utah State University
Year: 1978

description: The purpose of this study was to determine the degree of participation in family decision making among Korean home managers residing in Salt Lake City, Utah, with respect to selected variables, such as the length of stay in the United States, the husband's nationality, the husband's occupational status, the levels of education of both husband and wife, the difference in education between husband and wife, the wife's employment status, and the stage in the family life cycle. A questionnaire was constructed and administered by telephone interview to 72 Korean home managers in Salt Lake City.
On the whole, the pattern of participation in decision making among Korean home managers was different from that anticipated and unlike the pattern observed in previous research in different cultures. In general, we found more joint decision making and less husband dominance than expected. Most striking was the finding that the wife's employment was related to lower participation in decision making, rather than hi g her participation as had been found in previous studies. We also found t hat home managers with professional husbands participated in decision making much more than those with working-class husbands. It should be noted that the subjects were a special group whose husbands occupations were either professional, worker, student upper middle class occupations were almost totally absent. Another peculiarity of the respondents was the extremely high level of education, particularly that of husbands, almost half of whom held either a master 's or doctorate degree. With this peculiar educational background, the wife participated more in decision making when the husband had either a very high or low level of education. This relationship was consistent with most previous findings for the developed countries. However, the wife's education did not show any significant relationship with her participation in decision making. Wives with preschool-age children tended to participate less in decision making than those without children in this age group. Contrary to our expectation, we did not find any significant change in decision-making patterns with the number of years the respondents had lived in the United States. Being married to American husbands did not affect the pattern significantly. Final l y, we concluded that a family decision-making patterns were in transition from a traditional to a more democratic form among Korean families residing in the United States.

title: Dyadic Approach and Withdrawal Sequences of Preschool Children when Interacting with an Adult Male
Creators: name: Crane, Paul M.
Publisher: name: Utah State University
Year: 1978

description: Thirty-eight preschool children (20 male and 18 females) w ere filmed in a seated dyadic interaction with an adult experimenter. Frame- by-frame film analysis was done for head and arms of subjects and head, arms, and legs of experimenter for experimenter and subjects approach and withdrawal movements. Chi- square analysis were performed for the data both between and within zones with the following cells: approach-approach (A-A), experimenter and subject approach each other; approach-withdrawal (A-W), experimenter approaches and subject withdraws; withdrawal-approach (W -A), experimenter withdraws and subject approaches; withdrawal-withdrawal (W - W), both subject and experimenter withdraw.
The most frequent and significant movements for each zone and body part were A-Wand W -A. It was found that in the 3 foot zone the A-W cells (of the 2 X 2 contingency table) were the most frequent dyadic movements. For the 2 and 1 foot zones the W -A cells were the most frequent. For all three one-foot zones the W-W and A-A were respectively the least frequent dyadic interactional patterns. The intimate zone of personal space was found to be larger than the 18 inches previously identified for adults; it was found to be over 24 inches. Modifications for personal space and equilibrium theories to accommodate present findings are advanced.

description: The mechanism of core-collapse supernova explosions must draw on the energy provided by gravitational collapse and transfer the necessary fraction to the kinetic and internal energy of the ejecta. Despite many decades of concerted theoretical effort, the detailed mechanism of core-collapse supernova explosions is still unknown, but indications are strong that multi-D processes lie at its heart. This opens up the possibility of probing the supernova mechanism with gravitational waves, carrying direct dynamical information from the supernova engine deep inside a dying massive star. I present a concise overview of the physics and primary multi-D dynamics in neutrino-driven, magnetorotational, and acoustically-driven core-collapse supernova explosion scenarios. Discussing and contrasting estimates for the gravitational-wave emission characteristics of these mechanisms, I argue that their gravitational-wave signatures are clearly distinct and that the observation (or non-observation) of gravitational waves from a nearby core-collapse event could put strong constraints on the supernova mechanism.

description: In this thesis, I describe how the confirmational rigor applied to judicial nominees is related to whether a senator shares the party of the president. I first conduct a sentiment analysis and use the scores as an initial proxy for rigor with more negative/less positive results indicating greater rigor (and vice versa). To further substantiate these findings, I next present the results of collocation and topic model analyses which show the recurring themes of the hearings. Throughout, I provide a hand-content analysis of the confirmation hearing transcripts to give necessary context. I find that overall rigor applied to nominees moving between district and circuit courts decreases for senators who share the party of the president. At the same time, the overall rigor applied to these nominees increases for senators of the party opposite the president. Applying these same tests to nominees moving from a circuit court to the Supreme Court, I find a minimal increase in rigor applied to nominees by members of both parties. I conclude by discussing the impact of my results and commenting on ways to improve and expand my analysis.
Special Relativity and Superluminal Motions: a Discussion of Some Recent Experiments

Publisher: name: INFN Open Access Repository
Year: 2000

description: Some experiments, performed at Berkeley, Cologne, Florence, Vienna, Orsay and Rennes led to the claim that something seems to travel with a group velocity larger than the speed c of light in vacuum. Various other experimental results seem to point in the same direction: For instance, localized wavelet-type solutions of Maxwell equations have been found, both theoretically and experimentally, that travel with Superluminal speed. Even muonic and electronic neutrinos - it has been proposed - might be 'tachyons', since their square mass appears to be negative.With regard to the first-mentioned experiments, it was very recently claimed by Guenter Nimtz that those results with evanescent waves or 'tunneling photons' - implying Superluminal signal and impulse transmission - violate Einstein causality. In this note, on the contrary, we want to stress that all such results do not place relativistic causality in jeopardy, even if they refer to actual tachyonic motions: In fact, Special Relativity can cope even with Superluminal objects and waves. For instance, it is possible (at least in microphysics) to solve also the known causal paradoxes, devised for 'faster than light' motion, even if this is not widely recognized. Here we show, in detail and rigorously, how to solve the oldest causal paradox, originally proposed by Tolman, which is the kernel of many further tachyon paradoxes. The key to the solution is a careful application of tachyon mechanics, as it unambiguously follows from Special Relativity.

description: In this paper we investigate the influence of the leakage current on the performance of Silicon Drift Detectors.

Aiming at a mass production of SDDs for the Inner Tracking System of the ALICE experiment at LHC we propose a simple and fast measurement for a preliminary selection before passing to a detailed acceptance test.

description: The study of the 12C(14N,14N)12C reaction was performed at 28 and 35 MeV beam energies. The results were analyzed in the frame of the EFRDWBA (Exact-Finite-Range Distorted Wave Born Approximation) assuming the simultaneous and sequential transfer of a np pair. The angular distributions, fairly reproduced in the first case, confirm the validity of the generalized BCS (Bardeen-Cooper-Schrieffer) theory to explain this behaviour. Moreover, this process could be regarded as a possible Nuclear Josephson Effect.
title: Adolescent Friendship Pairs: Similarities in Identity Status Development, Behaviors, Attitudes, and Intentions
Creators: name: Akers, James F.
Publisher: name: Utah State University
Year: 1996

description: Similarities between adolescent friends have been established for many characteristics, including the physical, behavioral, psychological, academic, and social domains of development. Past research and theory also support the notion that psychological and behavioral characteristics are likely related to ego-identity characteristics. This study was primarily a test of the logical extension of the previous statements: Best friends are more similar than nonfriends on identity characteristics. It was also hypothesized that best friends are more similar than nonfriends on behaviors, attitudes, and intentions expected to be related to identity. A sample of 1,159 grade 10-12 students responded to a survey that included a measure of identity status levels, based on a modified Objective Measure of Ego Identity Status. The self-response survey also contained additional items that assessed behaviors, attitudes, and intentions. When comparing 198 pairs of mutually identified adolescent best friends and like numbers of pairs of non mutual best friends and randomly paired non friends, several tests of similarity indicated that best friends shared distinct similarities in ego identity. Magnitudes of similarity indicators were greater for measures of identity in specific content areas than for the global identity status levels or interpersonal and ideological domains. In addition, best friends were more similar than nonfriends on many behaviors, attitudes, and intentions expected to be related to identity. However, similarities of best friends were not related to the duration of the friendship. Weak relationships between identity and academics across grade levels suggested a possible reduction of identity similarities in friend pairs over time. No clear relationships were found between friends' similarities and friends' friendship strength. Finally, only inconsistent differences between females and males were found in the relationships of identity status levels, behaviors, attitudes, and intentions with friendship duration, friendship strength, and grade level.
title: Adolescent Leisure-Time Activity and Problem Behavior: The Integration of Three Major Explanatory Theories as a New
Creators: name: Yost, Gail B.
Publisher: name: Utah State University
Year: 1995

description: Adolescence has in recent decades gained attention as being salient for study of social trends. Increases in youth social problems are seen nationally, statewide, and locally. They include substance abuse, precocious sexual activity, related consequences of pregnancy and STDs, suicide and depression, truancy, running away, crime against property, and violent crime against persons.
This study integrates three major explanatory theories of adolescent behavior into a macro-synthesis. R. Jesser's Problem Behavior Theory emphasizes how problem behaviors do not occur singularly, nor do they justify unique prevention methods. T. Hirschi's Social Control Theory describes how adolescents with little or no attachment to their community are more likely to be involved in unconventional behaviors. E . Werner's Resilience framework relates adult support and mentoring in childhood and adolescence with lower risk of problems later in life.
This study examines how one element of this synthesis, adolescents' social environment, relates with social problems, or more specifically, how adolescent use of leisure time relates to problem behavior. A stratified random sample of 450 mail-out questionnaires yielded a 40% (181) response rate. Factor analysis placed 27 of 28 problem behavior variables into five subscales. The subscales were then regressed onto 11 individual and sumscore variables from eight hypotheses about adolescent leisure-time use.
Altogether, four of the eight hypotheses were supported by the data, demonstrating relationships between how and with whom adolescents use their leisure time, and their proneness toward problem behaviors. Specifically, unsupervised leisure-time activities were positively related to problem behaviors, sharing 16% of the variance. Organized leisure-time activities were negatively related to problem behaviors, sharing 9% of the variance. Adolescents who spent more time with family members and less time with peers demonstrated fewer problem behaviors, sharing 19% of the variance. Also, adolescents who confide their personal problems to adults, not peers, showed a lower tendency for problem behaviors, sharing 14% of the variance. The results support relationships between adolescent social environment, particularly leisure-time use, and problem behaviors.

The radiative effects of cloud particles are directly correlated with their wavelength-dependent optical properties. Therefore the incident stellar spectra may play an important role for the climatic effect of clouds.

description: The aim of this report is to summarize the R&D and the work done so far for the design of a photo-detector for a space experiment based on the AirWatch concept, focusing on the EUSO project proposed to ESA for installation on the International Space Station.The main results will be summarized, solutions to some problems will be presented and the most critical items requiring further study will be identified. A realistic baseline scheme for the photo-detector, based on the presently known information and constraints, is proposed. The outcome of these studies can be used to estimate the performance of EUSO and to provide input to further engineering studies. Finally an activity plan for the development of the photo-detector will be presented.
Envelope Solitons Versus Solitons

description: A theory involving a correspondence between envelope solitonlike solutions of the generalized nonlinear Schrödinger equation (GNLSE) and solitonlike solutions of the generalized Korteweg–de Vries equation (GKVdE) is developed within the context of the Madelung's fluid description (fluid counterpart description of the GNLSE). This correspondence, which, under suitable constraints, can be made invertible, seems to be very helpful for finding one family of solutions (whether envelope solitonlike solutions of the GNLSE or solitonlike solutions of the GKdVE) starting from the knowledge of the other family of solution (whether solitonlike solutions of the GKdVE or envelope solitonlike solutions of the GNLSE). The theory is successfully applied to wide classes of both modified nonlinear Schrödinger equation (MNLSE) and modified Korteweg–de Vries equation (MKVdE), for which bright and gray/dark solitonlike solutions are found. In particular, bright and gray/dark solitary waves are determined for the MNLSE with a quartic nonlinear potential in the modulus of the wavefunction (i.e. q1|Ψ|2 + q2|Ψ|4) as well as for the associated MKdVE. Furthermore, the well known bright and gray/dark envelope solitons of the cubic NLSE and the corresponding solitons of the associated standard KdVE are easily recovered from the present theory. Remarkably, this approach opens up the possibility to transfer all the know how concerning the instability criteria for solitonlike solutions of the MKdVE to the instability theory of envelope solitonlike solutions of the MNLSE.

description: We show that the scalar field that drives inflation can have a dynamical origin, being a strongly coupled right handed neutrino condensate. The resulting model is phenomenologically tightly constrained, and can be experimentally (dis)probed in the near future. The mass of the right handed neutrino obtained this way (a crucial ingredient to obtain the right light neutrino spectrum within the see-saw mechanism in a complete three generation framework) is related to that of the inflaton and both completely determine the inflation features that can be tested by current and planned experiments.

Classical versus quantum dynamics of the atomic Josephson junction

description: We compare the classical (mean-field) dynamics with the quantum dynamics of atomic Bose-Einstein condensates in double-well potentials. The quantum dynamics are computed using a simple scheme based upon the Raman-Nath equations. Two different methods for exciting a non-equilbrium state are considered: an asymmetry between the wells which is suddenly removed, and a periodic time oscillating asymmetry. The first method generates wave packets that lead to collapses and revivals of the expectation values of the macroscopic variables, and we calculate the time scale for these revivals. The second method permits the excitation of a single energy eigenstate of the many-particle system, including Schroedinger cat states. We also discuss a band theory interpretation of the energy level structure of an asymmetric double-well, thereby identifying analogies to Bloch oscillations and Bragg resonances. Both the Bloch and Bragg dynamics are purely quantum and are not contained in the mean-field treatment.

title: Anforderungen an ein Lehrwerk für Deutsch als Tertiärsprache in der Türkei

description: Englischkenntnisse gehören heute zu den elementaren Kulturtechniken. Dies hat zur Folge, dass auch in der Türkei wie in Europa und in vielen Ländern auf der Welt Englisch als Fremdsprache die führende Rolle übernommen hat. Deutsch folgt im türkischen Schulbereich konstant als führende 2. Fremdsprache nach Englisch (vgl. Tapan 2000 a/b; Polat und Tapan 2002). Diese Lernkonstellation hat Auswirkungen auf den Unterricht von Deutsch als Fremdsprache (DaF)und erfordert die Entwicklung von Lehrwerken für Deutsch als Tertiärsprache (L3) und eine Gestaltung und Durchführung des DaF Unterrichts nach den Leitlinien eines Tertiärsprachunterrichts, in diesem Fall Deutsch nach Englisch (vgl. Güler 2000; Polat 1998). Die Deutschkommission im türkischen Erziehungsministerium hat hierfür in der Türkei das regionale Lehrwerk „Hallo, Freunde!” für die 2. Fremdsprache nach Englisch erstellt (Barç•n, Çimen Cengiz, Camgöz, Tükenmez 2000). In der vorliegenden Arbeit werden die 3 Bände dieses Lehrwerks unter Tertiärsprachen-didaktischen Gesichtspunkten (vgl. Neuner und Hufeisen 2001 a/b) analysiert. Dabei wird insbesondere untersucht, inwieweit spezifische Fremdsprachenlernerfahrungen und -strategien der Schüler aus der ersten Fremdsprache beim Lernen von Deutsch als 2. Fremdsprache nach Englisch im Lehrwerk „Hallo, Freunde!” berücksichtigt, übertragen und entwickelt werden. Anschließend werden einige Vorschläge für ein Lehrwerk Deutsch als 2. Fremdsprache nach Englisch erarbeitet, die sich auf die neuere Diskussion zum Tertiärsprachenunterricht beziehen, wie sie von Neuner und Hufeisen angestoßen wurde, aber auch kontrastive Elemente zum Türkischen mit aufnehmen.

description: With the sequencing of the human genome completed, life science is entering the new era of structural and functional genomics and proteomics, in which the rapid identification and instantaneous sequencing of genes central to cellular processes and diseases leads to questions concerning the structure and function of the gene products. These new challenges require new methods of analysis and interdisciplinary efforts. In structural genomics, great progress has been made at so-called 'structure factories' . But there remains a deficit in methods for studying the relationship between structure and function in proteins. Recently, FTIR spectroscopy has emerged as the most powerful tool for structural/functional investigations in biology because of its ability to provide information on processes at multiple levels of organization. It has been used to investigate structural-functional relationships and molecular mechanisms at the atomic level in purified proteins, but also for large protein complexes; for investigations of environmental toxin pathways and programmed cell death in cells; and for tissue classification and disease diagnosis in tissue. Although, in all of these studies, SR IR light sources bring FTIR spectroscopy to the cutting edge in terms of the spectral range and spatial resolution, it remains true that it is used by a few specialized research groups. The new era of life science research coincides with an unprecedented development in European capabilities: we have two well established IRSR beamlines at Daresbury and Orsay, joined last year by three new ones and more are under construction or are planned. BASIE will bring together interdisciplinary scientists from 10 EU countries, ready to develop together specialized equipments, techniques and software optimized for a range of life science studies covering all levels of organization from molecules to tissues. In this way, BASIE may be the leader in Europe for these strategic researches.

description: Die langen und heftigen Diskussionen über den Stellenwert der Literatur in den Fremdsprachphilologien sind vorbei. Seit den 90-er Jahren versuchen Sprach- und Literaturdidaktiker, durch den Einsatz von Textauszügen oder ganzen literarischen Werken den Beitrag der Literatur zum Erwerb sprachlicher und (inter)kultureller Fertigkeiten praktisch hervorzuheben. Aus dieser Perspektive ist der vorliegende Band aus der bekannten Reihe der Giessener Beiträge zur Fremdsprachendidaktik geschrieben.

description: Even at absolute zero, the vacuum is seething with activity and behaves as a fluid in which moving objects dissipate their kinetic energy. The dynamical Casimir effect foresees that a metallic mirror put in motion in quantum vacuum gives rise to 'dissipated' energy in the form of real photons, called the Motion Induced Radiation. The final aim of this study is to present a solution to the main experimental difficulty, that is to realize the oscillating motion of the metallic wall at high frequency (10^9 ÷ 10^10 Hz). To obtain a fast moving wall we propose to switch an effective microwave mirror on and off in very short intervals of time changing the reflectivity of the semiconductor by shining pulsed laser beam on its surface. In this way a microwave mirror can be created and disappears at very high frequency, giving rise to a system equivalent to that of a fast moving metallic slab.
