A Power Supply Study for the Ramping Dipoles  of the Synchrotron Ring of the CNAO Project
Creators: name: M. Incurvati

Publisher: name: INFN Open Access Repository
Year: 2004

description: A hadrons (Protons and light Carbon ions) synchrotron accelerator is in construction under the responsibility of the CNAO (Centro Nazionale di Adroterapia Oncolociga) and INFN  finalized to the therapy of deep tumours. The accelerator complex is composed of two ion sources, a linear accelerator, a low energy and medium energy transfer lines that will transfer the ion beam to the synchrotron ring, where the beams will be accelerated to the prescribed beam energy according to the deep to which the beam energy (Bragg peak) and the dose amount must be released. Only one high energy transfer line is foreseen at this stage of the project. This transfer line will drive the beam to three treatment rooms, corresponding to three horizontal beam lines and one vertical beam line. Additional high energy transfer lines are foreseen in second phase of the project. The synchrotron ring is constituted of 16 H shaped bending dipoles that will accelerated the ion beams till to the requested extraction energy. These bending dipoles must be powered by means of a suitable power supply, 3000 A - 1600 V, that must accomplish the acceleration cycle in less than 1.6 s. The characteristics and performances of such  challenging power supply are described in this note. A 24 pulse SCR based topology is proposed, and control circuitry simulations are developed  together with a deep analysis of the expected output current shape in terms of current ripple and residual current error.

description: The cryogenic resonant gravitational wave detectors EXPLORER and NAUTILUS are able to detect cosmic ray showers. The experimental result leads to classify the responses in two categories:  many small signals, in most cases with small multiplicity, obeying the thermo-acoustic model, and few large signals, usually associated to large multiplicity, which exceed the thermo-acoustic model by orders of magnitude, and whose understanding is still under investigation. Using the low multiplicity showers, we make a relative calibration of the apparatuses, comparing the response of EXPLORER with that of NAUTILUS. This comparison turns out useful when searching for coincidences between gravitational waves detectors.

description: We propose to study features, optimization and commissioning of the CERN Closed Loop gas system used by the RPC muon detectors in experiment CMS at the LHC. Studies include a three-phase campaign both in low-radiation (cosmic rays at the CERN ISR test site) and high-radiation (at the CERN Gamma Irradiation Facility) environment. We describe dedicated RPC chambers tests and chemical analysis of filters and gas used which will allow us to fully characterize the Closed Loop system in view of the upcoming commissioning of the CMS RPC detector.

description: We theoretically demonstrate negative refraction and sub-wavelength resolution below the diffraction limit in the UV and extreme UV ranges using semiconductors. The metal-like re-sponse of typical semiconductors such as GaAs or GaP makes it possible to achieve negative refraction and super-guiding in resonant semiconductor/dielectric multilayer stacks, similar to what has been demonstrated in metallo-dielectric photonic band gap structures. The exploita-tion of this basic property in semiconductors raises the possibility of new, yet-untapped ap-plications in the UV and soft x-ray ranges.

description: We study the potential of the CNGS beam in constraining the parameter space of a model with one sterile neutrino separated from three active ones by an O(eV^2) mass-squared difference, Δm^2_SBL. We perform our analysis using the OPERA detector as a reference (our analysis can be upgraded including a detailed simulation of the ICARUS detector). We point out that the channel with the largest potential to constrain the sterile neutrino parameter space at the CNGS beam is υ_μ -> υ_τ. The reason for that is twofold: first, the active-sterile mixing angle that governs this oscillation is the less constrained by present experiments; second, this is the signal for which both OPERA and ICARUS have been designed, and thus benefits from an extremely low background. In our analysis we also took into account υ_μ -> υ_e oscillations. We find that the CNGS potential to look for sterile neutrinos is limited with nominal intensity of the beam, but it is significantly enhanced with a factor 2 to 10 increase in the neutrino flux. Data from both channels allow us, in this case, to constrain further the four-neutrino model parameter space. Our results hold for any value of Δm^2_SBL ≳ 0.1~eV^2, i.e. when oscillations driven by this mass-squared difference are averaged. We have also checked that the bound on θ_13 that can be put at the CNGS is not affected by the possible existence of sterile neutrinos.

title: Noticing Pretreatment Change: Effects on Therapeutic Outcome in Family Therapy
Creators: name: Johnson, Lee N.
Publisher: name: Utah State University
Year: 1995

description: Family therapy, similar to other mental health services, has focused on ways to make therapy brief or short term . One model of family therapy, the brief/solutions therapeutic orientation, claims that certain techniques can reduce the number of sessions. This therapeutic model focuses on the solutions clients bring with them to therapy. By focusing on clients' solutions and not their problems, the brief/solutions orientation claims that clients reach their goals more quickly, finish therapy more quickly, and are more satisfied with the services they receive . However, there is little empirical evidence to support these claims. This research specifically looked at the brief/solutions concept of pretreatment changes (changes clients make before the first therapy session) and the impact that noticing pretreatment changes as a therapeutic intervention had on therapeutic outcome variables of relationship functioning, goal attainment, problem solving, and communication. No evidence was found that noticing pretreatment changes influences therapeutic outcome. Evidence was found that pretreatment changes do not disappear when noticed. Ideas for future research are included.

description: We present magnetotransport studies performed on an extended set of (Ga,Mn)As samples at 4.2 K with longitudinal conductivities sigma_{xx} ranging from the low- to the high-conductivity regime. The anomalous Hall conductivity sigma_{xy}^(AH) is extracted from the measured longitudinal and Hall resistivities. A transition from sigma_{xy}^(AH)=20 Omega^{-1}cm^{-1} due to the Berry phase effect in the high-conductivity regime to a scaling relation sigma_{xy}^(AH) proportional to sigma_{xx}^{1.6} for low-conductivity samples is observed. This scaling relation is consistent with a recently developed unified theory of the anomalous Hall effect in the framework of the Keldysh formalism. It turns out to be independent of crystallographic orientation, growth conditions, Mn concentration, and strain, and can therefore be considered universal for low-conductivity (Ga,Mn)As. The relation plays a crucial role when deriving values of the hole concentration from magnetotransport measurements in low-conductivity (Ga,Mn)As. In addition, the hole diffusion constants for the high-conductivity samples are determined from the measured longitudinal conductivities.

title: Adolescent Sexual Behavior and Identity Development
Creators: name: King, Pamela Kay
Publisher: name: Utah State University
Year: 1993

description: The purpose of this study was to determine if there is a relationship between adolescent sexual behavior, motivations, and identity status. A review of the literature indicated that deviant behaviors covary, and that drug use and abuse and the motivations for same are related to identity status .
A questionnaire, including the Extended Objective Measure of Ego Identity Status(EOM-EIS) and a series of questions to gather information about sexual behaviors and motivations, was employed. The sample consisted of 579 university students ranging in age from 17 to 25.
The dependent variable (sexual behavior and motivation) was viewed through the categorical assignments of identity status achieved, moratorium, foreclosed, and diffused, as well as through individual scores. As anticipated there was a relationship between sexual behavior and identity status; specifically, risky sexual behavior was positively correlated with identity diffusion, and abstinence with identity foreclosure. Adolescents in all statuses were equally consistent users of contraception, not just identity achieved as hypothesized. There was not a clear response pattern mediated by identity status as initially anticipated. Implications were discussed.

description: With the goal of understanding the intricate behavior and dynamics of collections of neurons, we present superconducting circuits containing Josephson junctions that model biologically realistic neurons. These "Josephson junction neurons" reproduce many characteristic behaviors of biological neurons such as action potentials, refractory periods, and firing thresholds. They can be coupled together in ways that mimic electrical and chemical synapses. Using existing fabrication technologies, large interconnected networks of Josephson junction neurons would operate fully in parallel. They would be orders of magnitude faster than both traditional computer simulations and biological neural networks. Josephson junction neurons provide a new tool for exploring long-term large-scale dynamics for networks of neurons.

Year: 1993

description: The present study applies early field experience theory and developmental stages theory as the basis of teacher training in a junior college program in Taiwan. Two hundred sixty-six junior college students from two junior colleges were surveyed in order to ascertain what factors had an effect on the concept of teaching concerns. Comparisons were made among the following : with/ without preschool education background in senior high school, grade, school, age, fathers' educational levels, mothers' educational levels, and fathers' yearly income. The results indicate that early field experiences had a direct effect on teaching concerns. The students' year of study (freshmen vs sophomore) in junior college made a difference depending on whether they had been exposed to an early field experience. The groups that had a preschool education background had higher mean developmental-teaching-stage scores, in first (freshmen) study year, but lower mean scores in the second (sophomore) study year. The mean developmental teaching- stage scores for both study years of junior college students with preschool education background were very close to each other. Junior college students without a preschool education background in senior high had a higher mean developmental-teaching-stage score in the second year than in the first year.

description: Bilingualer Sachfachunterricht ist in aller Munde. Als spezifische, sachfachliches und fremdsprachliches Lernen integrierende Lehr- und Lernform in der Schulpraxis mehr oder minder etabliert, hat sich bilingualer Sachfachunterricht (biliSFU) in der letzten Dekade auch in der deutschsprachigen wissenschaftlichen Diskussion zu einem ernstzunehmenden Forschungsfeld mit interdisziplinärer Ausrichtung entwickelt. Diese Expansions- und Normalisierungstendenzen in Schulalltag und Forschung resultieren gegenwärtig u.a. in der Einsicht, dass einzelne fachdidaktische (sachfach- oder fremdsprachendidaktische) Zugriffe kaum geeignet sind, die Komplexität des biliSFU angemessen zu modellieren. So geht mit einer wachsenden Zahl an empirischen Studien zu Einzelfragestellungen die verstärkte Forderung nach einem integrativen Modell ‚bilingualer Didaktik‘ ebenso einher wie die Feststellung, dass eine „theoretische Grundlegung der spezifischen Verbindungen von sachfachlichen, fremdsprachlichen und interkulturellen Lernprozessen [...] noch aus[steht]“ (Küster 2004: 127) – oder aber bislang ausstand?

Die Dissertationen von Sow (1986), Ndong (1993) und Diop (2000) widmen sich ebenfalls dieser Debatte, gehen aber auch schon auf die Lage des Deutschangebots in einzelnen afrikanischen Ländern ein. Eine erste umfassende statistische Bestandsaufnahme und Darstellung der Situation der deutschen Sprache im Schul- und Hochschulwesen und im außerschulischen Bereich in Gesamtafrika liefert Böhm (2003). Hieran knüpft Bedi mit seiner sprach- und kulturpolitisch orientierten Dissertation an, kombiniert die Bestandsaufnahme mit der Darstellung der Legitimitätsdebatte und bietet Vorschläge zu einer bedarfsorientierteren Germanistik in Afrika an, die er vor allem in der Einführung eines neuen Schwerpunkts Fach- und Berufssprache Deutsch neben dem schon existierenden Schwerpunkt der Literatur sieht. Sein Ziel ist „die Analyse der Verbreitung der deutschen Sprache in Afrika, besonders im Schul- und Hochschulbereich, und der damit verfolgten Ziele sowohl der Deutschen als auch der Afrikaner“ sowie „die Relevanz der Lehre der deutschen Sprache als Fremdsprache für Afrika darzustellen“.

description: Adopting a discourse-analysis approach, we argue in line with van den Berg and Wu (2006) in showing that the particle le in Mandarin serves as a common ground coordination device, exhibiting a high degree of intersubjectivity, which is absent in the use of verbal -le. However, in view of the limit imposed by the data type of previous research, we observe the turn-taking behavior in natural, spontaneous, spoken data to further consolidate van den Berg and Wu‟s proposal. We argue that use of natural, spontaneous spoken data is essential in furthering our understanding of linguistic forms and their associated functions. Through this study, we hope we will be able to show and confirm the importance of data type in both the theoretical and pedagogical aspects of linguistic research.

description: Like other post-colonial states, Papua New Guinea continues to grapple with issues pertaining to land. In addition to being an important source of group identity, in resource rich Papua New Guinea, land is an important source of economic prosperity. Vigorous debate however, has ensued over the relationship between customary land tenure systems and economic growth, with official land registration being proposed as a more economically viable alternative to local systems of land tenure. This discussion paper, based on a seminar at AusAID, provides an overview of perspectives on land registration, which as demonstrated by violent protests in 1995 and 2000 is a highly contentious issue in Papua New Guinea. Peter Larmour provides a brief theoretical introduction followed by a chronological overview of official thinking about land registration in Papua New Guinea, concluding with a practical consideration of the mechanics of registering land in the country. Tim Curtin and Hartmut Holzknecht then provide competing perspectives on land registration, with Curtin advocating the establishment of individual land ownership in Papua New Guinea in order to accelerate economic growth, a task for which he believes customary land tenure is ill equipped. Conversely, Holzknecht argues that customary land tenure systems are highly productive (drawing upon the example of a motivated and productive community in Morobe Province), and that in any case, the Melanesian socio-political context is likely to confound attempts at land reform.

The dominant decay modes and final state products turn out to be very sensitive to the R-violating hierarchies. Mixing effects can be crucial in correctly deriving the relative magnitude of the various contributions, particularly for heavy flavours with phase space suppression. The study of the strength of different decay rates for the gravitino is also correlated to collider signatures expected from decays of the Next-to-Lightest Supersymmetric Particle (NLSP) and to single superparticle production.

description: Astrophysical objects frequently exhibit some irregularities or complex behaviour in their light curves. We focus primarily on hot stars, where both radial and non-radial pulsations are observed. One of the primary research goals is to determine physical parameters of stellar pulsations by analyzing their light curves or spectra, focusing on periodic or quasiperiodic behaviour. We analyse the feasibility of classical methods for period searches in a nonlinear chaotic system, such as the Rössler system, where a period does not exist at all. As an astrophysical application of the chaotic system, we utilize a simple model of stellar pulsation with two different sets of parameters corresponding to periodic and chaotic behaviour. For both models we create a synthetic signal, and then apply widely used methods for period finding, such as the phase dispersion method and periodograms. For comparison, a quasi-periodic signal is employed as well. The period analysis indicates periods even for the chaotic signal. Such periods are apparently spurious. This implies that it is very problematic to distinguish chaotic and quasiperiodic process by such an analysis only.

description: We extend the model of a 2$d$ solid to include a line of defects. Neighboring atoms on the defect line are connected by ?springs? of different strength and different cohesive energy with respect to the rest of the system. Using the Migdal-Kadanoff renormalization group we show that the elastic energy is an irrelevant field at the bulk critical point. For zero elastic energy this model reduces to the Potts model. By using Monte Carlo simulations of the 3- and 4-state Potts model on a square lattice with a line of defects, we confirm the renormalization-group prediction that for a defect interaction larger than the bulk interaction the order parameter of the defect line changes discontinuously while the defect energy varies continuously as a function of temperature at the bulk critical temperature.

Publisher: name: Utah State University
Year: 1970

description: The effects of sex and tutorial instruction were studied as they influenced the seriation ability of pre-school children. The research was conducted at the Utah State University Child Development Laboratories with 24 four year old children enrolled at that time. Twelve of the children, six girls and six boys, were given seriation tasks. The remaining 12 children, six girls and six boys, were not given any seriation training.
It was found that the 12 children who had received individualized instruction seriated significantly better on every task than the 12 children who had received no training. The children who were trained in seriation tasks also correctly transferred their learning of seriation from the original set of objects used in the training sessions to two other sets of size graded objects. The remaining 12 children did not make this transfer as successfully.
There was no significant difference in the seriation ability of boys and girls, although the girls receiving training improved more than the boys who were trained in seriation. This finding was attributed to the fact that the boys in both groups seriated slightly higher than t.he girls in both groups; therefore the boys who received no seriation training did not have as much room for improvement.
Particle size segregation in particulately fluidised beds.
Creators: name: Pruden, Barry Blythe
Publisher: name: University of British Columbia
Year: 2011

description: A paper by Jottrand which deals with particle size segregation in liquid-fluidised beds is examined critically, and an attempt has been made to extend and complement his work. It is assumed that the driving force for segregation of two groups of particles in a particulately fluidised bed is the difference in bulk density of the beds formed by each group of particles separately when subjected, to the same superficial velocity of the fluid. Accordingly the following equation for the bulk density difference between two groups of particles with unequal diameters was derived and studied experimentally: [ Equation omitted ] In the above equation, the subscripts L and S refer to large and small particles respectively, m is the index of fluid régime (m = 1 in Stokes region, m = 2 in Newton region), and n is the exponent in a Richardson-Zaki type expansion equation. It was found that for equal density particles the segregation tendency increased as the overall porosity, and hence ɛL was increased and as the diameter ratio (r) was increased. The tendency either to mix or to segregate was found to be very sensitive to changes in ϒ (density difference between large particles and fluid divided by the density difference between small particles and fluid), as is the bulk density difference in the above equation. It was observed that a bed could be either mixed or completely segregated, with one or the other size of particles occupying the upper portion of the bed, depending on the relative magnitudes of r and ϒ. It was also found that, while an increase in the factor ( ρpL-ρ) increased the bulk density difference, it did not increase the tendency of the particles to segregate, provided r and ϒ were kept constant. The values of m and n were found to change sufficiently, as the fluid régime was changed from the Stokes region to the Newton region, to account for the corresponding changes in segregation tendencies. Finally it was concluded that the bulk density difference equation predicted the right trends, insofar as mixing or segregation are concerned, but that the absolute magnitude of the predicted bulk density difference was not uniquely correlated with the observed phenomena, when the particle density was varied at constant r and ϒ . The applicability of a reduced bulk density difference was suggested by the limited data available.

description: The past twenty-five years has brought about a substantial increase in the number of American women participating in the labor force. In 1940, approximately 12.8 million women were involved in employment outside the home; this was 25 percent of the total female population 14 years of age and over. By 1964, the number of employed women had doubled; there were then 25.8 million women workers. Out-of-the-home employment was actively engaging 37 percent of American women (7, p. 301). However, not only has there been an increase in the number of workers; there are also changes in the percent of women involved, the number of years a woman spends in active participation in the labor force, and in the work cycle of employed women.

description: Im elektronischen Bildzeitalter wird die Lebenswelt unserer Lerner im Wesentlichen durch die Dominanz von Bildlichkeit geprägt. In vielen Lebensbereichen junger Erwachsener nehmen Einfluss und Relevanz audiovisueller Medien stetig zu. Durch den Einsatz audiovisueller Medien im Allgemeinen und Spielfilmen im Besonderen könnte der Unterricht Deutsch als Fremdsprache auf die Rezeptionsgewohnheiten junger Fremdsprachenlerner reagieren. In der Berücksichtigung der Alltagserfahrungen unserer Lernerinnen und Lerner steckt ein enormes Synergiepotenzial, das einerseits zu einem fruchtbaren und gewinnbringenden Lernprozess, andererseits auch zu mehr Spaß und Freude im Unterricht führen kann. Bei räumlich weiten Entfernungen zum Zielsprachenland liegt es nahe, sprachlich-kulturelle, interkulturelle sowie landeskundliche Aspekte vermehrt via Fernsehen/Satellit und Video/DVD in die Klassenräume zu holen. Der vorliegende Beitrag geht der Frage nach, inwieweit die Arbeit mit Filmen tatsächlich im universitären DaF-Unterricht Taiwans implementiert wird. Anhand einer empirisch quantitativen Studie, die an sieben taiwanischen Hochschulen mit Deutsch als Hauptfach durchgeführt wurde, soll untersucht werden, welchen Stellenwert Filmmaterialien und audiovisuelle Lernformen im gegenwärtigen Deutschunterricht einnehmen. Im Zuge der empirischen Erhebung wurde ein standardisierter Fragebogen eingesetzt, um grundlegende Tendenzen in Bezug auf Medieneinsatz und -präferenzen im Unterricht Deutsch als Fremdsprache zu konstatieren. Es wurden Studierende im fortgeschrittenen Lernstadium zu ihren Medieneinstellungen und -gewohnheiten, den Stellenwert von Medien im Fremdsprachenunterricht im Allgemeinen sowie die Rolle von Filmen im Deutschunterricht im Speziellen befragt.

description: It is shown that a state that is factorizable in the Hilbert space corresponding to some choice of degrees of freedom, becomes entangled for a different choice of degrees of freedom. Therefore, entanglement is not a special case but is ubiquitous in quantum systems. Simple examples are calculated and a general proof is provided. The physical relevance of the change of tensor product structure is mentioned.

title: An Interdisciplinary Theoretical Framework for the Mailed Questionnaire Process and the Development of a Theory on Immediacy and Salience as Significant Variables of Response Rates
Creators: name: Christensen, Maribeth
Publisher: name: Utah State University

description: The mailed questionnaire research process developed historically as part of the survey research movement, with guidelines and models drawn from an array of scientific research methods and disciplines. Although the mailed questionnaire has become one of the most popular research instruments for obtaining data beyond the reach of the observer, the response bias generated from the generally low return rate of the mailed questionnaire survey has remained a problem. For over three decades researchers have generated a plethora of research on the effectiveness of the various aspects of the mailed questionnaire process and the resultant impact of various constructs on survey return. But despite these efforts, researchers have not succeeded collectively in producing a clear, compelling, or consistent set of principles that, if followed, will produce high response rates in mailed questionnaire research . With the certainty that more knowledge and constructs will be generated in all areas of the mailed questionnaire process, scholars have issued a call for a viable theory to direct future research efforts on response rates . Therefore, the purpose of this study was to address that need . The dissertation research reported in this paper accomplished five major objectives. It (a) developed an interdisciplinary theoretical framework for the mailed questionnaire process; (b) identified 13 determinants of response costs in the mailed questionnaire process; (c) proposed immediacy and salience as the most significant determinant variables of response rates, from a synthesis of the research literature with the theoretical framework; (d) proposed a theory and theoretical model that explain and illustrate the interaction of immediacy and salience in determining response rate levels; and (e) recommended a method for testing the proposed theory and for utilizing the proposed theory to achieve high response rates in future mailed questionnaire studies.

description: The massive field theory approach in fixed space dimensions $d=3$ is applied to investigate a dilute solution of long-flexible polymer chains in a good solvent between two parallel repulsive walls, two inert walls and for the mixed case of one inert and one repulsive wall. The well known correspondence between the field theoretical $ϕ^4$ O(n)-vector model in the limit $n\to 0$ and the behavior of long-flexible polymer chains in a good solvent is used to calculate the depletion interaction potential and the depletion force up to one-loop order. Our investigations include modification of renormalization scheme for the case of two inert walls. The obtained results confirm that the depletion interaction potential and the resulting depletion force between two repulsive walls are weaker for chains with excluded volume interaction (EVI) than for ideal chains, because the EVI effectively reduces the depletion effect near the walls. Our results are in qualitative agreement with previous theoretical investigations, experimental results and with results of Monte Carlo simulations.

description: Grimms Märchen bieten schönes Unterrichtsmaterial für den DaF-Unterricht und dienen i.d.R. nur dem Erwerb der deutschen Sprache. Denn zum einem sind die meisten Märchenmotive allgemein bekannt. Zum anderen gehören die Grimmschen Märchen zur Weltliteratur in einfacher Form und Sprache. Auch bieten die vielen vorhandenen Variationen Möglichkeiten zum Vergleich, vor allem aus einer interkulturellen Perspektive. Da jedes Volksmärchen der symbolische Ausdruck eines Volkes ist, haben die kulturellen Hintergründe und ethischen Anschauungen einen entscheidenden Einfluss auf die Gestaltung von Märchenfiguren und -handlungen. So können ähnliche Märchenmotive in verschiedenen Kulturkreisen unterschiedliche Erzählformen annehmen. Die vorliegende Arbeit hat also das Ziel, anhand unterrichtspraxisbezogener Beispiele, Grimms Märchen mit der chinesischen Variation, auch mit der taiwanischen, in Form und Motiv zu vergleichen, z. B. „Rotkäppchen“ mit dem chinesischen Volksmärchen „Tigeroma“, und deutsche Tierbräutigam-Märchen mit den chinesischen Tierbraut-Märchen. Dabei werden die verschiedenen Mentalitäten, Sitten und Bräuche hervorgehoben, die die jeweiligen Märchenfassungen geprägt haben.

description: We present a series of simulations of turbulent stratified protostellar discs with the goal of characterizing the settling of dust throughout a minimum-mass solar nebula. We compare the evolution of both compact spherical grains, as well as highly fractal grains. Our simulations use a shearing-box formulation to study the evolution of dust grains locally within the disc, and collectively our simulations span the entire extent of a typical accretion disc. The dust is stirred by gas that undergoes MRI-driven turbulence. This establishes a steady state scale height for the dust that is different for dust of different sizes. This sedimentation of dust is an important first step in planet formation and we predict that ALMA should be able to observationally verify its existence. When significant sedimentation occurs, the dust will participate in a streaming instability that significantly enhances the dust density. We show that the streaming instability is pervasive in the outer disc. We characterize the scale heights of dust whose size ranges from a few microns to a few centimeters. We find that for spherical grains, a power-law relationship develops for the scale height with grain size, with a slope that is slightly steeper than -1/2. The sedimentation is strongest in the outer disc and increases for large grains. The results presented here show that direct measurements of grain settling can be made by ALMA and we present favorable conditions for observability. The streaming instability should also be directly observable and we provide conditions for directly observing it. We calculate collision rates and growth rates for the dust grains in our simulations of various sizes colliding with other grains, and find that these rates are significantly enhanced through the density enhancement arising from the streaming instability.

description: The direct limit of electric dipole moment (EDM) and direct search for dark matter by EDM interaction are considered as including the electromagnetic nuclear form factor, in case that the dark matter candidate is a Dirac particle. The WIMP electric dipole moment constrained by direct searches must be lower than 7*10^(-22)e cm for WIMP mass of 100 GeV to satisfy the current experimental exclusion limits at XENON10 and CDMS II. We also consider the CP violation of EDM and the WIMP discovery by EDM intereaction in the future.
