Metamaterials for light rays: ray optics without wave-optical analog in the ray-optics limit

description: Volumes of sub-wavelength electromagnetic elements can act like homogeneous materials: metamaterials. In analogy, sheets of optical elements such as prisms can act ray-optically like homogeneous sheet materials. In this sense, such sheets can be considered to be metamaterials for light rays (METATOYs). METATOYs realize new and unusual transformations of the directions of transmitted light rays. We study here, in the ray-optics and scalar-wave limits, the wave-optical analog of such transformations, and we show that such an analog does not always exist. Perhaps, this is the reason why many of the ray-optical possibilities offered by METATOYs have never before been considered.

description: We have analysed high-precision photometry of 77 double-mode RR Lyrae (RRd) stars observed by NASA's Kepler-K2 mission during Campaigns 1-18. Among those stars, we have identified several low-period ratio variables, belonging either to a subclass of "anomalous" RRd stars (Soszyński et al., 2016) or to a separate shorter-period subclass recently identified by Prudil et al. (2017). A non-radial mode with the period ratio of $P_{\rm x}/P_{\rm 1} \sim 0.615$ has been detected in most RRd stars of our sample. In majority of these variables, at least one subharmonic of the non-radial frequency is also present. Our findings indicate that excitation of the non-radial mode is a common property of the RRd stars. The same non-radial pulsation is also commonly detected in the RRc stars. We show that properties of this puzzling mode are essentially the same in both groups of RR Lyrae-type pulsators.

Year: 2024

description: In a world characterized by resource scarcity, particularly in terms of skilled labor and materials, the imperative to maximize existing resources has never been more pronounced. This necessity extends beyond traditional perspectives, encompassing sectors with a significant impact on society. This article introduces a research concept aimed at harnessing the potential of Road Digital Twins (RDTs) to enhance planning and building permit (PBP) processes. In the dynamic realm of urban development, decision-makers are captivated by the intricate interplay between roads, buildings, and neighborhoods. At the heart of this evolving landscape is the emergence of RDTs, exerting a transformative influence on the urban fabric. A compelling aspect of RDT development lies in its profound impact on PBP processes, introducing nuanced dimensions to decision-making dynamics. As RDTs seamlessly integrate into the urban context, they infuse 3D city models with a rich interconnectedness that extends beyond the physical confines of roads and buildings. Within this paradigm, the role of RDTs in PBP processes becomes evident, providing a wealth of information poised to reshape decision-making at crucial junctures. The PBP process, when viewed through the lens of RDTs, assumes a catalytic role for acceleration, improvement, facilitation, and influence, impacting both PBP authorities and applicants alike.

Vehicle-sensor-based pavement surface condition monitoring based on an optical fibre computing framework
Creators: name: Wang, Xiang
Publisher: name: Society of Photo-optical Instrumentation Engineers
Year: 2025

description: This study is the primary research towards physical optical reservoir computing for road surface monitoring. Road surface monitoring traditionally utilizes specialized equipment on a road assessment vehicle to monitor road conditions, such as the profile, the roughness, the cracks, and the friction of the road pavement. These specific road assessment vehicles cannot provide up-to-date road surface conditions between two survey tasks, which limits the decision-making by using road data. Acceleration data collected by the sensors on the vehicles to achieve low-cost and high-efficiency road surface data acquisition based on the mobile vehicle platforms showing potential for road surface monitoring as an alternative approach. In this study, a physical optical fibre computing framework was utilized for road pavement surface fluctuation detection with acceleration data of the vehicles. Specifically, the acceleration data was obtained by an accelerometer on the vehicle for a road distance of 10 km and the corresponding road pavement surface fluctuation data was calculated from the road profile collected by a road assessment vehicle with a laser. The data was extracted from a road dataset. A time-delay optical fibre computing framework uses the normalized acceleration data in the z direction as the input signals and uses the dynamics of the physical optical fibre computing structure to calculate the temporary signals to be trained with linear regression to predict the road pavement surface fluctuations. The results showed that the physical optical computing structure achieved road surface fluctuation prediction while the parameters of the physical optical computing structure have a great influence on the prediction of the road surface data. This study provides insights into the development of physical computing for road surface monitoring in the future.

description: Spectropolarimetric measurements of gamma-ray burst (GRB) optical afterglows contain polarization information for both continuum and absorption lines. Based on the Zeeman effect, an absorption line in a strong magnetic field is polarized and split into a triplet. In this paper, we solve the polarization radiative transfer equations of the absorption lines, and obtain the degree of linear polarization of the absorption lines as a function of the optical depth. In order to effectively measure the degree of linear polarization for the absorption lines, a magnetic field strength of at least $10^3$ G is required. The metal elements that produce the polarized absorption lines should be sufficiently abundant and have large oscillation strengths or Einstein absorption coefficients. We encourage both polarization measurements and high-dispersion observations of the absorption lines in order to detect the triplet structure in early GRB optical afterglows.

Efficiency and Characteristics of MICP in Environments with Elevated Salinity, Diminished Oxygen, and Lowered Temperature: A Microfluidics Investigation

description: Microbially Induced Carbonate Precipitation (MICP) shows promise for enhancing soil strength, but environmental factors significantly affect its mechanisms. The feasibility of MICP in challenging conditions, such as the soil around piles in shallow seabeds during winter,characterized by high salinity, low oxygen, and cold temperatures,remains uncertain due to limited research. To address this gap, we employed microfluidic techniques and advanced measurement tools, including Raman spectroscopy and SEM, to assess how these conditions influence bacterial growth, calcium carbonate crystallization, and porous medium permeability through MICP.Our findings indicate that cold temperatures notably hinder bacterial growth, while high salinity and low oxygen also play critical roles, particularly reducing bacterial attachment. In seawater environments, high salinity and cold temperatures significantly affect calcium carbonate crystal shape and type; low oxygen has a lesser impact. Specifically, high salinity reduces crystal quantity by 20.2% with minimal effect on diameter, while low oxygen increases diameter by 20.3% but decreases quantity by 50.9%. Cold temperatures decrease diameter by 36.9% without much effect on quantity.After six injections of the cementation solution, MICP treated samples showed a chemical transformation efficiency of 20.6% compared to DI water, primarily due to cold temperatures (contributing 40.1%). An exponential decline in permeability with increasing calcium carbonate content was observed, leading to the categorization of calcium carbonate generation into fast and slow decay types. This study provides insights for optimizing mineralization in marine conditions and emphasizes how environmental factors impact MICP performance, presenting challenges for engineering applications.

description: We give an introduction to a notion of weak dependence which is more general than mixing and allows to treat for example processes driven by discrete innovations as they appear with time series bootstrap. As a typical example, we analyze autoregressive processes and their bootstrap analogues in detail and show how weak dependence can be easily derived from a contraction property of the process. Furthermore, we provide an overview of classes of processes possessing the property of weak dependence and describe important probabilistic results under such an assumption.

High-voltage measurement techniques
Creators: name: Halim, Armand Gregoire
Publisher: name: University of British Columbia
Year: 2010

description: The Department of Electrical Engineering at the University of British Columbia acquired a high-voltage test set in 1979 for teaching and research purposes. To make this test set useful for experiments which undergraduate students can do themselves, various additions and modifications had to be made. This thesis describes these additions and modifications. First, a Faraday cage had to be constructed with interlocking safety circuits. Experiments were then developed to show basic high-voltage phenomena with AC voltage, with DC voltage, and with impulse voltages. Considerable modifications were required to eliminate noise in the impulse measuring system.
A Comprehensive optimization study of Microbially Induced Carbonate Precipitation (MICP) for soil strength enhancement: impact of biochemical and environmental factors

description: Microbially Induced Carbonate Precipitation (MICP) is a biocementation technique that modifies the hydraulic and mechanical properties of porous materials using bacterial solutions. This study evaluates the efficiency of various MICP protocols under different environmental conditions, utilizing two bacterial strains: S. pasteurii and S. aquimarina, to optimize soil strength. Results indicate that bacterial strain and cementation solution concentration significantly affect biochemical outcomes, while temperature is the primary environmental factor. The efficiency of S. pasteurii's chemical conversion ranged from 40% to 80%, compared to only about 20% for S. aquimarina. MICP treatment with S. pasteurii produced CaCO3 content between 5% and 7%, whereas S. aquimarina yielded 0.5% to 1.5%. An optimized cementation solution concentration of 0.5 M was critical for maximum efficiency. The ideal operational temperature is between 20 and 35C, with salinity and oxygen levels having minimal effects. Although salinity influences carbonate crystal characteristics, its impact on Unconfined Compressive Strength (UCS) of treated soil is minor. Samples from a one-phase treatment at pH 6.0 to 7.5 showed UCS strength approximately half that of a two phase treatment. These findings suggest promising applications for MICP in enhancing strength in both terrestrial and marine environments.

Turbulence and Capillary Waves on Bubbles

Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: We present a link between the theory of deep water waves and that of bubble surface perturbations. Theory correspondence is shown analytically for small wavelengths in the linear regime and investigated numerically in the nonlinear regime. To do so, we develop the second-order spatial perturbation equations for the Rayleigh-Plesset equation and solve them numerically. Our code is publicly available. Studying capillary waves on stable bubbles, we recreate the Kolmogorov-Zakharov spectrum predicted by weak turbulence theory, putting wave turbulence theory to use for bubbles. In this investigation, it seems that curvature does not affect turbulent properties. Calculated bubble surface qualitatively responds to low gravity experiments. The link demonstrated opens new possibilities for studying several bubble phenomena, including sonoluminescence and cavitation, using the extensive tools developed in the wave turbulence framework.
Quantum resonances in an atom-optical delta-kicked harmonic oscillator

description: Under certain conditions, the quantum delta-kicked harmonic oscillator displays quantum resonances. We consider an atom-optical realization of the delta-kicked harmonic oscillator, and present a theoretical discussion of the quantum resonances that could be observed in such a system. Having outlined our model of the physical system we derive the values at which quantum resonances occur and relate these to potential experimental parameters. We discuss the observable effects of the quantum resonances, using the results of numerical simulations. We develop a physical explanation for the quantum resonances based on symmetries shared between the classical phase space and the quantum-mechanical time evolution operator. We explore the evolution of coherent states in the system by reformulating the dynamics in terms of a mapping over an infinite, two-dimensional set of coefficients, from which we derive an analytic expression for the evolution of a coherent state at quantum resonance.

description: An infinite family of axially symmetric thin disks of finite radius is presented. The family of disks is obtained by means of a method developed by Hunter and contains, as its first member, the Kalnajs disk. The surface densities of the disks present a maximum at the center of the disk and then decrease smoothly to zero at the edge, in such a way that the mass distribution of the higher members of the family is more concentrated at the center. The first member of the family have a circular velocity proportional to the radius, representing thus a uniformly rotating disk. On the other hand, the circular velocities of the other members of the family increases from a value of zero at the center of the disks until a maximum and then decreases smoothly until a finite value at the edge of the disks, in such a way that for the higher members of the family the maximum value of the circular velocity is attained nearest the center of the disks.

Restoring State Control Over Forest Resources Through Administrative Procedures: Evidence From a Community Forestry Programme in Central Java, Indonesia
Creators: name: Maryudi, Ahmad
Publisher: name: Austrian Journal of South-East Asian Studies
Year: 2012

description: In recent years, community forestry has emerged as a means to reform power constellations with regard to forest governance. Through community forestry, the central state promised to devolve several forest rights to local communities and encouraged them to get involved in decision making processes and the implementation of forest activities. However, experience in some countries indicates that the implementation of community forestry programmes is rarely followed by genuine power devolution to local forest users. Instead, these programmes may even serve as a means to retain or restore the central state’s control over forests. Using a case study of a community forestry programme implemented in Java, Indonesia, by a state forest company, this paper argues that the implementation of community forestry is also driven by the state’s interests to regain control over the forests. Research in eight villages in Central Java province reveals that the community forestry programmes are carefully structured according to numerous administrative procedures and establish a mode of control through a bureaucratic design.

description: The interplay among anisotropic magnetic terms, such as the bond-dependent Kitaev interactions and single-ion anisotropy, plays a key role in stabilizing the finite-temperature ferromagnetism in the two-dimensional compound $\rm{CrSiTe_3}$. While the Heisenberg interaction is predominant in this material, a recent work shows that it is rather sensitive to the compressive strain, leading to a variety of phases, possibly including a sought-after Kitaev quantum spin liquid [C. Xu, \textit{et. al.}, Phys. Rev. Lett. \textbf{124}, 087205 (2020)]. To further understand these states, we establish the quantum phase diagram of a related bond-directional spin-$3/2$ model by the density-matrix renormalization group method. As the Heisenberg coupling varies from ferromagnetic to antiferromagnetic, three magnetically ordered phases, i.e., a ferromagnetic phase, a $120^\circ$ phase and an antiferromagnetic phase, appear consecutively. All the phases are separated by first-order phase transitions, as revealed by the kinks in the ground-state energy and the jumps in the magnetic order parameters. However, no positive evidence of the quantum spin liquid state is found and possible reasons are discussed briefly.

A converter model for the digital simulation of transients in AC/DC transmission systems
Creators: name: Chiu, But-Chung
Publisher: name: University of British Columbia
Year: 2010

description: The successful application of HVDC transmission links requires correct predictions of the performance of the dc link and the ac system to which it is interconnected. Whatever the system configuration, the steady-state, dynamic and transient behaviour of the associated dc and ac systems are mostly interdependent. To simulate these phenomena with digital computers, converter stations must be modelled in more detail than as simple dc sources. This thesis discusses the development and implementation of a converter model which enables the converter bridge circuits to be represented in detail and the valve ignition to be controlled in the constant current mode. The model has been added to the U.B.C. Electromagnetic Transients Program to permit simulations of the complete ac/dc system. It is used to analyze the harmonics during steady-state operation, and to compare the results with those obtained from conventional (approximate) formulae. In a transient case, the new model gives closer agreement with field measurements than the simplified model used before.
Lowland Participation in the Irredentist ‘Highlands Liberation Movement’ in Vietnam, 1955-1975

description: In the field of mainland South-East Asian history, particular attention has been granted to highlandlowland relations following the central argument James Scott presented in The Art of Not Being Governed: An Anarchist History of Upland South-East Asia. Scott’s analytical perspective echoes a long-term trend of scholarly examinations in the region. In a similar fashion, historical examinations of the Vietnam War period view the so-called ‘highlands liberation movement’ or the Unifi ed Front for the Struggle of the Oppressed Races (FULRO) through the lens of a highland-lowland dichotomy. However, based on an examination of the biography of the Cham Muslim leader Les Kosem and various FULRO documents, this article challenges dominant assumptions based on Scott’s argument and argues that a focus on minority majority relations is essential for understanding the origins of irredentist claims of indigenous peoples in the region.

description: The computation of the elastic registration of two simple curves in higher dimensions and therefore of the elastic shape distance between them has been investigated by Srivastava et al. Assuming the first curve has one or more starting points, and the second curve has only one, they accomplish the computation, one starting point of the first curve at a time, by minimizing an L2 type distance between them based on alternating computations of optimal diffeomorphisms of the unit interval and optimal rotation matrices that reparametrize and rotate, respectively, one of the curves. We recreate the work by Srivastava et al., but in contrast to it, again for curves in any dimension, we present a Dynamic Programming algorithm for computing optimal diffeomorphisms that is linear, and justify in a purely algebraic manner the usual algorithm for computing optimal rotation matrices, the Kabsch-Umeyama algorithm, which is based on the computation of the singular value decomposition of a matrix. In addition, we minimize the L2 type distance with a procedure that alternates computations of optimal diffeomorphisms with successive computations of optimal rotation matrices for all starting points of the first curve. Carrying out computations this way is not only more efficient all by itself, but, if both curves are closed, allows applications of the Fast Fourier Transform for computing successively in an even more efficient manner, optimal rotation matrices for all starting points of the first curve.

description: It is widely accepted that the progenitors of core collapse SNe are young massive stars and therefore their host galaxies are mostly spiral or irregular galaxies dominated by a young stellar population. Surprisingly, among morphologically classified hosts of core collapse SNe, we find 22 cases where the host has been classified as an Elliptical or S0 galaxy. To clarify this apparent contradiction, we carry out a detailed morphological study and an extensive literature search for additional information on the sample objects. Our results are as follows: 1. Of 22 "early type" objects, 17 are in fact misclassified spiral galaxies, one is a misclassified irregular, and one is a misclassified ring galaxy. 2. Of the 3 objects maintaining the early type classification, one (NGC2768) is a suspected merger remnant, another (NGC4589) is definitely a merger, and the third (NGC2274) is in close interaction. The presence of some amount of young stellar population in these galaxies is therefore not unexpected. These results confirm the presence of a limited, but significant, number of core collapse SNe in galaxies generally classified of early type. In all cases, anyway, there are independent indicators of the presence in host galaxies of recent star formation due to merging or gravitational interaction.

description: The classification of certain class of static solutions for the Einstein-Gauss-Bonnet theory in vacuum is presented. The spacelike section of the class of metrics under consideration is a warped product of the real line with a nontrivial base manifold. For arbitrary values of the Gauss-Bonnet coupling, the base manifold must be Einstein with an additional scalar restriction. The geometry of the boundary can be relaxed only when the Gauss-Bonnet coupling is related with the cosmological and Newton constants, so that the theory admits a unique maximally symmetric solution. This additional freedom in the boundary metric allows the existence of three main branches of geometries in the bulk, containing new black holes and wormholes in vacuum.

description: The afterglow of GRB 050401 presents several novel and interesting features : [1] An initially faster decay in optical band than in X-rays. [2] A break in the X-ray light curve after $\sim$ 0.06 day with an unusual slope after the break. [3] The X-ray afterglow does not show any spectral evolution across the break while the R band light curve does not show any break. We have modeled the observed multi-band evolution of the afterglow of GRB 050401 as originating in a two component jet, interpreting the break in X-ray light curve as due to lateral expansion of a narrow collimated outflow which dominates the X-ray emission. The optical emission is attributed to a wider jet component. Our model reproduces all the observed features of multi-band afterglow of GRB 050401. We present optical observations of GRB 050401 using the 104-cm Sampurnanand Telescope at ARIES, Nainital. Results of the analysis of multi-band data are presented and compared with GRB 030329, the first reported case of double jet.

description: Hydrodynamic equations are used to identify the final state reached by a freely evolving granular gas above but close to its shear instability. The theory predicts the formation of a two bands shear state with a steady density profile. There is a modulation between temperature and density profiles as a consequence of the energy balance, the density fluctuations remaining small, without producing clustering. Moreover, the time dependence of the velocity field can be scaled out with the squared root of the average temperature of the system. The latter follows the Haff law, but with an effective cooling rate that is smaller than that of the free homogeneous state. The theoretical predictions are compared with numerical results for inelastic hard disks obtained by using the direct Monte Carlo simulation method, and a good agreement is obtained for low inelasticity.

Kontinuitäten im Wandel: Handlungskoordinationen von Frauenrechtsaktivistinnen in Aceh
Creators: name: Großmann, Kristina
Publisher: name: Austrian Journal of South-East Asian Studies
Year: 2013

description: Muslimische Aktivistinnen nehmen in Aceh eine wichtige Rolle ein, indem sie soziale und politische Missstände zu beseitigen versuchen und Frauenrechte fördern. Im Aushandlungsprozess ihrer Visionen eines neuen Acehs positionieren sie sich zwischen ihrer persönlichen islamischen Religiosität und acehischen Identität sowie zwischen dem Nationalstaat und internationalen Konventionen. Die Frage nach den Erfahrungen und Einfl ussfaktoren, die Motive, Ziele, Strategien und Umsetzung frauenrechtlicher Arbeit von Aktivistinnen in Aceh bedingen, steht im Mittelpunkt dieses Artikels. Basierend auf einer 11-monatigen ethnologischen Feldforschung und biographischen Interviews in Aceh, argumentiert die Autorin, dass muslimische Aktivistinnen ihre frauenfördernde Arbeit nicht mit eigenen Erfahrungen der Benachteiligung durch patriarchale Strukturen begründen, sondern die anfängliche Triebfeder in der Betroff enheit, Empathie und Solidarität mit physisch und psychisch versehrten weiblichen Kriegsopfern sehen. Nach steigender Institutionalisierung und Kommerzialisierung von Wiederaufbau- und Entwicklungshilfe nach dem Tsunami 2004 empfinden Aktivistinnen hohe Diskrepanzen zwischen den Zielen der GeldgeberInnen und lokalen Organisationen und plädieren für eine Rückbesinnung auf die Bedürfnisse von Frauen an der Basis.

description: Honeycomb layered oxides have garnered tremendous research interest in a wide swath of disciplines owing not only to the myriad physicochemical properties they exhibit, but also their rich crystal structural versatility. Herein, a comprehensive crystallographic study of a sodium-based $\rm Na_2Ni_2TeO_6$ honeycomb layered oxide has been performed using atomic-resolution transmission electron microscopy, elucidating a plethora of atomic arrangement (stacking) disorders in the pristine material. Stacking disorders in the arrangement of honeycomb metal slab layers (stacking faults) occur predominantly perpendicular to the slabs with long-range coherence length and enlisting edge dislocations in some domains. Moreover, the periodic arrangement of the distribution of alkali atoms is altered by the occurrence of stacking faults. The multitude of disorders innate in $\rm Na_2Ni_2TeO_6$ envisage broad implications in the functionalities of related honeycomb layered oxide materials and hold promise in bolstering renewed interest in their material science.

description: Why do security cameras, sensors, and siri use cloud servers instead of on-board computation? The lack of very-low-power, high-performance chips greatly limits the ability to field untethered edge devices. We present the NV-1, a new low-power ASIC AI processor that greatly accelerates parallel processing (> 10X) with dramatic reduction in energy consumption (> 100X), via many parallel combined processor-memory units, i.e., a drastically non-von-Neumann architecture, allowing very large numbers of independent processing streams without bottlenecks due to typical monolithic memory. The current initial prototype fab arises from a successful co-development effort between algorithm- and software-driven architectural design and VLSI design realities. An innovative communication protocol minimizes power usage, and data transport costs among nodes were vastly reduced by eliminating the address bus, through local target address matching. Throughout the development process, the software and architecture teams were able to innovate alongside the circuit design team's implementation effort. A digital twin of the proposed hardware was developed early on to ensure that the technical implementation met the architectural specifications, and indeed the predicted performance metrics have now been thoroughly verified in real hardware test data. The resulting device is currently being used in a fielded edge sensor application; additional proofs of principle are in progress demonstrating the proof on the ground of this new real-world extremely low-power high-performance ASIC device.

Lightning surge propagation in overhead lines and gas insulated bus-ducts and cables
Creators: name: Lee, Kai-Chung
Publisher: name: University of British Columbia
Year: 2010

description: The propagation characteristics of lightning surges in compressed SF₆ gas insulated power substation was studied using an electromagnetic transients program. Numerical models were developed to represent the behaviour of different system components especially under lightning over-voltage conditions. The characteristics of lightning surge propagation in overhead multi-phase untransposed transmission lines was analysed first. Modal analysis, together with special rotation techniques to fit time domain solutions were then used to simulate the wave propagation in multi-phase untransposed line in an electromagnetic transients program. Non-linear voltage-dependent corona attenuation and distortion phenomena were also investigated. Available field test results could be duplicated to within 5%. The characteristics of lightning surge propagation in multi-phase single-core SF₆ cables was studied next. A program was developed to obtain the cable parameters for typical cable configurations. The amount of core current returning through its own sheath and through the earth were computed to illustrate the single phase cable representation for wave propagation in single core SF₆ cables.

description: Objectives Chewing gums containing antiseptics or other antimicrobial substances may be effective in reducing plaque and gingivitis. Therefore, the aim of this randomized placebo-controlled clinical trial was to investigate the efficacy of a novel antimicrobial chewing gum containing essential oils (cinnamon, lemon, peppermint) and extracts on reduction of dental plaque and gingivitis as well as on oral health-related quality of life (OHRQoL) in adolescent orthodontic patients.
Materials 52 patients (11-22 years of age) were randomly assigned to use a test chewing gum (COVIDGUM, Clevergum) or a commercially available control chewing gum over a period of 10 days. Approximal plaque index (API), papillary bleeding index (PBI) and an OHRQoL questionnaire for children (COHIP-G19) were assessed at baseline (BL), after 10 days (10d) and 30 days (30d). In addition, oral health and oral hygiene related questions of the COHIP-G19 questionnaire were evaluated separately in subscales at each timepoint. Data were analyzed using non-parametrical statistical procedures (α = 0.05).
Results API and PBI decreased significantly over time from BL to 10d and from BL to 30d in both groups, without significant differences between the groups. In both groups, the COHIP-G19 score, oral health subscale and oral hygiene subscale decreased significantly over time. Regarding the oral hygiene subscale, the test group showed significantly better scores at 30d (p = 0.011).
Conclusion Both chewing gums performed similarly effective in terms of reducing plaque accumulation and gingival inflammation and improving OHRQoL.
Clinical relevance Chewing gums without antimicrobial ingredients may be sufficient to decrease plaque accumulation and gingival inflammation.

description: The motion of test particles in the gravitational fields generated by the first four members of the infinite family of generalized Kalnajs discs, is studied. In first instance, we analyze the stability of circular orbits under radial and vertical perturbations and describe the behavior of general equatorial orbits and so we find that radial stability and vertical instability dominate such disc models. Then we study bounded axially symmetric orbits by using the Poincare surfaces of section and Lyapunov characteristic numbers and find chaos in the case of disc-crossing orbits and completely regular motion in other cases.
