Force and Moment Characteristics of a Rhombi Tessellated Non-Pneumatic Tire
Authors: Kumar Anand Suresh , Kumar Ramarathnam Krishna 
Published: June 2016

ABSTRACTThere has been a recent spate of activities in the design of non-pneumatic tires (NPTs). The validation of a NPT's design is incomplete unless its performance is compared with an equivalent pneumatic tire. Apart from its static behavior, an evaluation of the tire's performance can be done by observing its force and moment (F&M) characteristics. In the present work, an NPT has been designed with an aperiodic rhombi tessellated spoke acting as the load bearing member, where the “unit cell” design is based on the vertical, circumferential, and lateral stiffness offered by the structure. A three-dimensional finite element model has been used to capture the mechanics of load distribution in the spoke, contact patch, and variation of contact pressure distribution when the tire is subjected to different operating conditions. SIMULIA/Abaqus has been used to conduct static loading, acceleration/braking, and cornering analyses. The F&M characteristics have been extracted from these simulations and compared with those of a 165/70R14 passenger car tire. The variation in the vertical and circumferential stiffness based on the spoke geometry has also been highlighted. The use of conventional pneumatic tire's belts to alter the NPT's lateral stiffness, despite the tire behaving like a “bottom loader,” adds uniqueness to the design. The NPT's capability to match the pneumatic tire's performance and the variability observed in the tire's F&M characteristics reiterate the freedom available in NPT design, thus providing the opportunity to have similar tires with varying performance characteristics.
Effect of Sodium Hyaluronate Added to Topical Corticosteroids in Chronic Rhinosinusitis with Nasal Polyposis
Authors: Cantone Elena , Iengo Maurizio 
Published: June 2016

Background Available medical treatments for chronic rhinosinusitis (CRS) with nasal polyposis (CRSwNP) comprise systemic and topical therapies. Although topical corticosteroids are effective in the treatment of CRS, they are not completely devoid of adverse effects. Thus, care has to be taken when long-term treatments are prescribed. There is recent evidence that sodium hyaluronate (SH), the major component of many extracellular matrices, promotes tissue healing, including activation and moderation of the inflammatory responses, cell proliferation, migration, and angiogenesis. Objective The aim of the study was to evaluate clinical outcomes and quality of life in two groups of patients with CRSwNP treated with topical corticosteroids alone or in combination with 9 mg of high-molecular-weight SH. Methods The impact of treatments was determined by using nasal endoscopy and validated quality of life questionnaires (Short Form-36, 22-item Sino-Nasal Outcome Test, visual analog scale [VAS]). Eighty subjects who had CRS with grade IV nasal polyposis: 40 diagnosed with allergic rhinitis (AR) and 40 with non-allergic-eosinophilic rhinitis (NARES) based on skin-prick test and nasal cytology results, were divided in two groups. Group I comprised 40 subjects (20 AR and 20 NARES), who received mometasone furoate plus SH; group II comprised 40 subjects (20 AR and 20 NARES), who received mometasone furoate plus saline solution alone. All the patients were followed up for 3 months. Results At baseline, no statistically significant differences were observed between the groups and the VAS score showed a moderate-to-severe degree of disease. After treatments, Lund and Kennedy, Short Form-36, 22-item Sino-Nasal Outcome Test, and VAS scores were statistically significant in both groups but slightly in favor of the group I and in the subjects with allergic CRSwNP. Conclusion Analysis of our data indicated that an SH supplement to standard corticosteroid seems to play an important role in improving the severity of symptoms, the endoscopic appearance, and discomfort associated with CRSwNP. This effect seems to be strongest in patients with allergic CRSwNP.

<p class="Abstract">Epilepsy is an abnormality of nervous system showing seizures. Despite, the known antiepileptic activity of plants possessing anti-oxidant properties, <em>Silybum marianum</em> has not been studied yet. Therefore, present experiment was planned to evaluate antiepileptic potential of <em>S. marianum</em> (100, 200 and 300 mg/kg) seeds ethanol extract in pentylenetetrazol-induced kindled mice (n = 30). <em>S. marianum</em> seed extract (300 mg/kg) provided significant protection against pentylenetetrazol-induced convulsions (seizure intensity, latency and lethality) comparable with reference drug (valproic acid). Furthermore, 300 mg/kg/day dose was effective to prevent oxidative stress causing significant decrease in the lipid peroxidation (1.4 ± 0.4 nmol/mg protein) and increased superoxide dismutase (0.4 ± 0.1 μmol/mg protein) and catalase activity (4.7 ± 0.8 U/mL) of mice brain as compared to induced untreated group (p&lt;0.05). It was concluded that antiepileptic activity of <em>S. marianum</em> seeds was due to its anti-oxidant property.</p><p class="Abstract"><strong>Video Clip</strong></p><p class="Abstract"><a href="https://www.youtube.com/v/NAh_04UzpYM">Experimental induction of seizures:</a> 10 min 4 sec</p><p> </p>

Authors: Reddy Patakota Sudarsana , Chamkha Ali J. 
Published: June 2016

The effect of thermophoresis on heat and mass transfer flow of a micropolar fluid in the presence of Soret and Dufour effects past a vertical porous plate have been investigated . The transformed conservation equations are solved numerically using an optimized, extensively validated, variational finite element analysis. The influence of important non-dimensional parameter, Suction parameter ( ), Soret parameter (Sr), Dufour parameter (Du) and thermophoretic parameter (?) on velocity, angular velocity (micro-rotation), temperature and concentration fields as well as shear stress, Nusselt number and Sherwood number are examined in detail and the results are shown in graphically and in tabular form to know the physical importance of the problem. It is found that the imposition of wall fluid suction (V0>0) in this present problem of flow has the effect of depreciating the velocity, micro-rotation, temperature and concentration boundary layer thicknesses at every finite value of ?.

Published: June 2016

In order to compare the frictional resistance of three kinds of ships hull coatings (Foul Release, SPC copper, SPC TBT) in the unfouled conditions, the numerical studies have been made. Simulations have been carried out for different Reynolds numbers in the range of 2.85 ×  5.5 × based on the plate length and flow velocity. Antifouling coatings have a larger mean roughness than Foul Release. The results have indicated that frictional resistance coefficient of Foul Release test plate is lower than SPC copper and SPC TBT test plates. The total resistance obtained by computational fluid dynamics has been compared with the experimental data and good agreement in results has been found which those have shown the ability of CFD modeling in calculating of fluid flow resistance by considering the coating characteristics.
DETECTING EXOMOONS AROUND SELF-LUMINOUS GIANT EXOPLANETS THROUGH POLARIZATION
Authors: Sengupta Sujan , Marley Mark S. 
Published: June 2016

ABSTRACT
Many of the directly imaged self-luminous gas-giant exoplanets have been found to have cloudy atmospheres. Scattering of the emergent thermal radiation from these planets by the dust grains in their atmospheres should locally give rise to significant linear polarization of the emitted radiation. However, the observable disk-averaged polarization should be zero if the planet is spherically symmetric. Rotation-induced oblateness may yield a net non-zero disk-averaged polarization if the planets have sufficiently high spin rotation velocity. On the other hand, when a large natural satellite or exomoon transits a planet with a cloudy atmosphere along the line of sight, the asymmetry induced during the transit should give rise to a net non-zero, time-resolved linear polarization signal. The peak amplitude of such time-dependent polarization may be detectable even for slowly rotating exoplanets. Therefore, we suggest that large exomoons around directly imaged self-luminous exoplanets may be detectable through time-resolved imaging polarimetry. Adopting detailed atmospheric models for several values of effective temperature and surface gravity that are appropriate for self-luminous exoplanets, we present the polarization profiles of these objects in the infrared during the transit phase and estimate the peak amplitude of polarization that occurs during the inner contacts of the transit ingress/egress phase. The peak polarization is predicted to range between 0.1% and 0.3% in the infrared.

ABSTRACT
We present a tomographic cosmic shear study from the Deep Lens Survey (DLS), which, providing a limiting magnitude

(

), is designed as a precursor Large Synoptic Survey Telescope (LSST) survey with an emphasis on depth. Using five tomographic redshift bins, we study their auto- and cross-correlations to constrain cosmological parameters. We use a luminosity-dependent nonlinear model to account for the astrophysical systematics originating from intrinsic alignments of galaxy shapes. We find that the cosmological leverage of the DLS is among the highest among existing

deg2 cosmic shear surveys. Combining the DLS tomography with the 9 yr results of the Wilkinson Microwave Anisotropy Probe (WMAP9) gives

THE IMPACT OF STELLAR FEEDBACK ON THE STRUCTURE, SIZE, AND MORPHOLOGY OF GALAXIES IN MILKY-WAY-SIZED DARK MATTER HALOS
Authors: Agertz Oscar , Kravtsov Andrey V. 
Published: June 2016

ABSTRACT
We use cosmological zoom-in simulations of galaxy formation in a Milky-Way-sized halo started from identical initial conditions to investigate the evolution of galaxy sizes, baryon fractions, morphologies, and angular momenta in runs with different parameters of the star formation–feedback cycle. Our fiducial model with a high local star formation efficiency, which results in efficient feedback, produces a realistic late-type galaxy that matches the evolution of basic properties of late-type galaxies: stellar mass, disk size, morphology dominated by a kinematically cold disk, stellar and gas surface density profiles, and specific angular momentum. We argue that feedback’s role in this success is twofold: (1) removal of low angular momentum gas, and (2) maintaining a low disk-to-halo mass fraction, which suppresses disk instabilities that lead to angular momentum redistribution and a central concentration of baryons. However, our model with a low local star formation efficiency, but large energy input per supernova, chosen to produce a galaxy with a similar star formation history as our fiducial model, leads to a highly irregular galaxy with no kinematically cold component, overly extended stellar distribution, and low angular momentum. This indicates that only when feedback is allowed to become vigorous via locally efficient star formation in dense cold gas do resulting galaxy sizes, gas/stellar surface density profiles, and stellar disk angular momenta agree with observed z = 0 galaxies.
THE RINGS OF CHARIKLO UNDER CLOSE ENCOUNTERS WITH THE GIANT PLANETS
Authors: Araujo R. A. N. , Sfair R. , Winter O. C. 
Published: June 2016

ABSTRACT
The Centaur population is composed of minor bodies wandering between the giant planets that frequently perform close gravitational encounters with these planets, leading to a chaotic orbital evolution. Recently, the discovery of two well-defined narrow rings was announced around the Centaur 10199 Chariklo. The rings are assumed to be in the equatorial plane of Chariklo and to have circular orbits. The existence of a well-defined system of rings around a body in such a perturbed orbital region poses an interesting new problem. Are the rings of Chariklo stable when perturbed by close gravitational encounters with the giant planets? Our approach to address this question consisted of forward and backward numerical simulations of 729 clones of Chariklo, with similar initial orbits, for a period of 100 Myr. We found, on average, that each clone experiences during its lifetime more than 150 close encounters with the giant planets within one Hill radius of the planet in question. We identified some extreme close encounters that were able to significantly disrupt or disturb the rings of Chariklo. About 3% of the clones lose their rings and about 4% of the clones have their rings significantly disturbed. Therefore, our results show that in most cases (more than 90%), the close encounters with the giant planets do not affect the stability of the rings in Chariklo-like systems. Thus, if there is an efficient mechanism that creates the rings, then these structures may be common among these kinds of Centaurs.
ION IRRADIATION OF ETHANE AND WATER MIXTURE ICE AT 15 K: IMPLICATIONS FOR THE SOLAR SYSTEM AND THE ISM
Authors: Barros A. L. F. de , Silveira E. F da , Fulvio D. , Rothard H. , Boduch P. 
Published: June 2016

ABSTRACT
Solid water has been observed on the surface of many different astronomical objects and is the dominant ice present in the universe, from the solar system (detected on the surface of some asteroids, planets and their satellites, trans-Neptunian objects [TNOs], comets, etc.) to dense cold interstellar clouds (where interstellar dust grains are covered with water-rich ices). Ethane has been detected across the solar system, from the atmosphere of the giant planets and the surface of Saturn’s satellite Titan to various comets and TNOs. To date, there were no experiments focused on icy mixtures of C2H6 and H2O exposed to ion irradiation simulating cosmic rays, a case study for many astronomical environments in which C2H6 has been detected. In this work, the radiolysis of a C2H6:H2O (2:3) ice mixture bombarded by a 40 MeV58Ni11+ ion beam is studied. The chemical evolution of the molecular species existing in the sample is monitored by a Fourier transform infrared spectrometer. The analysis of ethane, water, and molecular products in solid phase was performed. Induced chemical reactions in C2H6:H2O ice produce 13 daughter molecular species. Their formation and dissociation cross sections are determined. Furthermore, atomic carbon, oxygen, and hydrogen budgets are determined and used to verify the stoichiometry of the most abundantly formed molecular species. The results are discussed in the view of solar system and interstellar medium chemistry. The study presented here should be regarded as a first step in laboratory works dedicated to simulate the effect of cosmic radiation on multicomponent mixtures involving C2H6 and H2O.

ABSTRACT
Two cold gas giant planets orbiting a G-type main-sequence star in the galactic disk were previously discovered in the high-magnification microlensing event OGLE-2012-BLG-0026. Here, we present revised host star flux measurements and a refined model for the two-planet system using additional light curve data. We performed high angular resolution adaptive optics imaging with the Keck and Subaru telescopes at two epochs while the source star was still amplified. We detected the lens flux, H = 16.39 ± 0.08. The lens, a disk star, is brighter than predicted from the modeling in the original study. We revisited the light curve modeling using additional photometric data from the B&C telescope in New Zealand and CTIO 1.3 m H-band light curve. We then include the Keck and Subaru adaptive optic observation constraints. The system is composed of a ∼4–9 Gyr lens star of M
lens = 1.06 ± 0.05 M
⊙ at a distance of D
lens = 4.0 ± 0.3 kpc, orbited by two giant planets of 0.145 ± 0.008 M
Jup and 0.86 ± 0.06 M
Jup, with projected separations of 4.0 ± 0.5 au and 4.8 ± 0.7 au, respectively. Because the lens is brighter than the source star by 16 ± 8% in H, with no other blend within one arcsec, it will be possible to estimate its metallicity using subsequent IR spectroscopy with 8–10 m class telescopes. By adding a constraint on the metallicity it will be possible to refine the age of the system.

Cet article interroge les limites de l’approche globale de l’UE en prenant le cas de la politique de non-prolifération commune face à l’Iran. En articulant sociologie des secteurs et sociologie des rôles, nous avançons l’idée que la mobilisation et l’abandon soudain de l’approche globale constituent l’objectivation de luttes inter- et intra-sectorielles qui s’inscrivent dans le contexte de négociations internationales. À partir de cette reconstitution socio-historique de la non-institutionnalisation de l’approche globale, nous démontrons que l’institutionnalisation de l’Europe de la politique étrangère ne se fait pas forcément par l’« européanisation » de ses producteurs.
