Увеличение объемов производства модифицированных крахмалов, расширение их ассортимента на основе использования зернового и клубневого крахмалов, повышение импортозамещения являются актуальными задачами для крахмалопаточной отрасли. Одно из основных направлений повышения импортозамещения модифицированных крахмалов - разработка и внедрение на предприятиях отрасли новых технологий по производству крахмалофосфатов с повышенной вязкостью и стабильностью крахмальных клейстеров при механическом воздействии.
Исследовано влияние различных технологических факторов на изменение физико-химических свойств нативного амилопектинового крахмала при его экструзионной обработке в присутствии фосфоросодержащих реагентов. В качестве реагентов использовали триполифосфат натрия и гексаметафосфат натрия. Изучено влияние расхода реагентов, температуры обработки крахмала, частоты вращения шнеков на физико-химические свойства амилопектинового фосфатного крахмала. Определено, что наибольшую динамическую вязкость и водосвязывающую способность имели образцы амилопектинового фосфатного крахмала, полученные при температуре обработки крахмала 160…170 оС и применении двух реагентов: триполифосфата натрия и гексаметафосфата натрия, расход которых составлял по 1,0 % к массе сухих веществ крахмала. Проведены исследования по изучению влияния частоты вращения шнеков на свойства амилопектинового фосфатного крахмала. Рекомендована оптимальная частота вращения шнеков для получения высококачественного продукта. Показано, что дисперсии амилопектинового фосфатного крахмала устойчивы к механическим воздействиям (перемешиванию). Результаты исследований служат основой для разработки нормативной документации и внедрения технологии на предприятиях крахмалопаточной отрасли с целью увеличения объема выпуска модифицированных крахмалов отечественного производства и расширения их ассортимента.

Published: August 2019

Abstract
We present a detailed analysis of the orbital stability of the HD 181433 planetary system, finding it to exhibit strong dynamical instability across a wide range of orbital eccentricities, semimajor axes, and mutual inclinations. We also analyze the behavior of an alternative system architecture, proposed by Campanella, and find that it offers greater stability than the original solution, as a result of the planets being trapped in strong mutual resonance. We take advantage of more recent observations to perform a full refit of the system, producing a new planetary solution. The best-fit orbit for HD 181433 d now places the planet at a semimajor axis of 6.60 ± 0.22 au, with an eccentricity of 0.469 ± 0.013. Extensive simulations of this new system architecture reveal it to be dynamically stable across a broad range of potential orbital parameter space, increasing our confidence that the new solution represents the ground truth of the system. Our work highlights the advantage of performing dynamical simulations of candidate planetary systems in concert with the orbital fitting process, as well as supporting the continuing monitoring of radial velocity planet search targets.
FUSE and IUE Spectroscopy of the Prototype Dwarf Nova ER Ursa Majoris During Quiescence
Authors: Guzman Giannina , Sion Edward M. , Godon Patrick 
Published: August 2019

Abstract
ER Ursae Majoris is the prototype for a subset of SU UMa-type dwarf novae characterized by short cycle times between outburst, high outburst frequency, and negative superhumps. It suffers superoutbursts every 43 days, lasting 20 days, normal outbursts every 4 days, and has an outburst amplitude of 3 mag. We have carried out a far-ultraviolet (FUV) spectral analysis of ER UMa in quiescence, by fitting Far Ultraviolet Spectroscopic Explorer and International Ultraviolet Explorer spectra with model accretion disks and high-gravity photosphere models. Using the Gaia parallax distance and an orbital inclination of 50°, we find that during the brief quiescence of only four days, the accretion rate is 7.3 × 10−11
M
⊙ yr−1, with the ER UMa white dwarf contributing 55% of the FUV flux and the accretion disk contributing the remaining 45% of the flux. The white dwarf in ER UMa is markedly hotter (32,000 K) than the other white dwarfs in dwarf novae below the cataclymic variable (CV) period gap, which have typical temperatures of ∼15,000 K. For higher inclinations of 60°–75°, the accretion rates that we derive are roughly an order of magnitude higher, (1–3) × 10−10

Abstract
Hydration is a major mineral alteration process in primitive asteroids and it might occur in comet nuclei; however, it is poorly understood at low temperatures, especially below the freezing point of water. Long-duration experiments were performed with exposures of amorphous silicate nanoparticles and organic compounds (glycine and ribose) to D2O and D2O + NH3 ices and vapors at temperatures of −17°C and −27°C for 10–120 days; and with exposure of amorphous silicates to H2O vapor/liquid at >25°C for 10 days. The amorphous silicates were analyzed by X-ray diffraction and Fourier-transform infrared spectroscopy, and recovery of organic molecules was determined by liquid chromatography–mass spectrometry. No hydration of amorphous silicates or organic compounds was observed after exposure at temperatures below −17°C for 120 days to ices with or without NH3, whereas hydration of the amorphous silicates was observed in experiments above room temperature. The estimated thermal history of the nucleus of the short-period comet 67P/Churyumov–Gerasimenko indicates that the surface temperature does not exceed −45°C, even in a region exposed to strong solar illumination during the perihelion passage. Assuming hydration is controlled by the collision frequency between H2O molecules and dust particles, the present results indicate that cometary dust does not hydrate for more than 25–510 periods of comet 67P. This is consistent with the absence of phyllosilicates on 67P and suggests that amino acids and sugars have not been altered.

Le décor architectural en bande à guirlandes naît et se diffuse avec ses diverses variantes à partir de Pergame à l’époque attalide, puis connaît une brillante expansion dans l’Asie Mineure hellénistique. D’autres foyers artistiques comme Magnésie du Méandre, Éphèse et enfin Aphrodisias de Carie développeront aux ii e et i er s. av. J.-C. des schémas innovants qui se répandront avec plus ou moins de succès dans les provinces de l’empire romain à partir du règne d’Auguste.
Two bronze vases in the Musée du Petit Palais
Authors: Oliver Andrew 
Published: August 2019

Deux vases en bronze attribués à la période romaine font partie des collections d’œuvres d’art qu’Auguste Dutuit légua au Petit Palais à son décès, en 1902. En 1980, ils furent considérés comme des créations à l’antique du xix e siècle. Néanmoins, les reproductions de plusieurs dessins du début du xix e s. appartenant à la Lewis Walpole Library de l’université de Yale ont récemment circulé dans la communauté scientifique. Ils attestent qu’au xviii e s., les deux vases faisaient partie de la collection d’Horace Walpole en Angleterre. De fait, l’un d’entre eux fut publié dès 1707, alors qu’il se trouvait encore à Rome. Cet article retrace d’abord leur provenance et leur passage dans plusieurs collections privées notables. Il démontre ensuite que plusieurs aspects stylistiques – notamment les décors figurés et floraux en relief sur leur panse – initialement considérés comme indicateurs de leur origine moderne, confirment au contraire leur origine antique.
Loi de finances 2018 et fiscalité du capital
Authors: Antonin Céline , Touzé Vincent 
Published: August 2019

Dans cet article, nous étudions l’impact de la loi de finances 2018 (LF2018) sur les taux d’imposition marginaux supérieurs. Nous revenons d’abord sur l’évolution de la fiscalité du capital au cours du temps, son incidence sur les choix économiques et sur la mesure des taux marginaux d’imposition. Nous discutons ensuite des arguments économiques qui ont conduit à l’adoption du prélèvement forfaitaire unique (PFU) et à la suppression partielle de l’impôt de solidarité sur la fortune (ISF). Enfin, nous calculons les taux marginaux économiques avant réforme pour différentes classes d’actifs, puis évaluons l’impact de la loi de finances 2018. Nous montrons que le remplacement de l’ISF par l’impôt sur la fortune immobilière (IFI) a permis de ramener les taux marginaux supérieurs en dessous de 100 %. Nos calculs mettent également en évidence deux effets de la réforme sur l’assurance vie : le PFU réduit la fiscalité pour des retraits avant 8 ans ; pour la partie des contrats supérieure à 150 000 euros, la fiscalité devient indépendante de l’horizon de détention. L’imposition des plus-values réalisées sur valeurs mobilières ne dépend également plus de l’horizon de détention. De plus, la baisse de l’impôt sur les sociétés contribue à réduire les taux marginaux de façon non négligeable. Enfin, c’est au niveau des revenus obligataires que la baisse de fiscalité est la plus forte.
L’évolution de long terme des transmissions de patrimoine et de leur imposition en France
Authors: Dherbécourt Clément 
Published: August 2019

Cet article analyse l’évolution des taux effectifs d’imposition des héritages et donations en France des années 1870 à nos jours. Sur le long terme le taux d’imposition a évolué du fait des changements de barèmes, de la manière dont l’administration a évalué les biens transmis, mais aussi des changements dans la structure des transmissions. La période 1930-1950 est celle où les successions et donations ont été les plus taxées, notamment en ligne directe. À partir des années 1950 on assiste à une grande divergence des taux d’imposition entre les enfants et les conjoints d’une part et les parents éloignés et non-parents d’autre part. En ligne indirecte, le taux d’imposition moyen a très fortement augmenté au cours du temps pour atteindre 20 à 25 % aujourd’hui. À long terme l’augmentation de la part des successions et donations en ligne directe dans l’ensemble des transmissions a eu pour effet de modérer le taux moyen d’imposition. Cet effet pourrait se retourner dans les prochaines décennies du fait des évolutions démographiques.
Treatment of Ocular Neuralgia After Refractive Surgery With Bilateral Orbital Steroid and Anesthetic Injections
Authors: Yalamanchili Siri P. , Hertle Richard W. 
Published: August 2019

PURPOSE:
To describe a patient with chronic periocular pain after bilateral photorefractive keratectomy (PRK), termed ocular neuralgia, that was controlled with regular orbital steroid and anesthetic injections.

METHODS:
Case report.

RESULTS:
A 21-year-old man presented 3 months following bilateral PRK surgery in severe bilateral orbital pain. Previous treatments included topical (artificial tears, corticosteroids, and nonsteroidal anti-inflammatory drugs [NSAIDs]) and oral (NSAIDs, opioids, and pregabalin) therapies with minimal pain relief. A bilateral orbital triamcinolone acetonide 40 mg/cc and 0.25% bupivacaine injection was done after a successful, diagnostic unilateral 0.25% bupivacaine injection. Following bilateral bupivacaine and triamcinolone acetonide injections, pain intensity improved from a range of 7 to 9 to a range of 1 to 3 (out of 10). Repeat injections have been regularly performed over the past 3 years, allowing the patient to experience improved symptoms lasting from 4 to 9 months.

CONCLUSIONS:
Regular orbital nerve blocks can provide relief from neuralgic ocular pain and may be considered as a potential treatment option after failure of medical management.

Abstract. New ice cores retrieved from the Taylor Glacier (Antarctica) blue
ice area contain ice and air spanning the Marine Isotope Stage (MIS) 5–4
transition, a period of global cooling and ice sheet expansion. We determine
chronologies for the ice and air bubbles in the new ice cores by visually
matching variations in gas- and ice-phase tracers to preexisting ice core
records. The chronologies reveal an ice age–gas age difference (Δage) approaching 10 ka during MIS 4, implying very low snow accumulation in
the Taylor Glacier accumulation zone. A revised chronology for the analogous
section of the Taylor Dome ice core (84 to 55 ka), located to the south of
the Taylor Glacier accumulation zone, shows that Δage did not exceed
3 ka. The difference in Δage between the two records during MIS 4 is
similar in magnitude but opposite in direction to what is observed at the
Last Glacial Maximum. This relationship implies that a spatial gradient in
snow accumulation existed across the Taylor Dome region during MIS 4 that
was oriented in the opposite direction of the accumulation gradient during
the Last Glacial Maximum.

Image based quantitative comparisons indicate heightened megabenthos diversity and abundance at a site of weak hydrocarbon seepage in the southwestern Barents Sea
Authors: Sen Arunima , Chitkara Cheshtaa , Hong Wei-Li , Lepland Aivo , Cochrane Sabine , di Primio Rolando , Brunstad Harald 
Published: August 2019

Background
High primary productivity in the midst of high toxicity defines hydrocarbon seeps; this feature usually results in significantly higher biomass, but in lower diversity communities at seeps rather than in the surrounding non-seep benthos. Qualitative estimates indicate that this dichotomy does not necessarily hold true in high latitude regions with respect to megafauna. Instead, high latitude seeps appear to function as local hotspots of both megafaunal diversity and abundance, although quantitative studies do not exist. In this study, we tested this hypothesis quantitatively by comparing georeferenced seafloor mosaics of a seep in the southwestern Barents Sea with the adjacent non-seep seafloor.

Methods
Seafloor images of the Svanefjell seep site and the adjacent non seep-influenced background seabed in the southwestern Barents Sea were used to construct georeferenced mosaics. All megafauna were enumerated and mapped on these mosaics and comparisons of the communities at the seep site and the non-seep background site were compared. Sediment push cores were taken in order to assess the sediment geochemical environment.

Results
Taxonomic richness and abundance were both considerably higher at the seep site than the non-seep location. However, taxa were fewer at the seep site compared to other seeps in the Barents Sea or the Arctic, which is likely due to the Svanefjell seep site exhibiting relatively low seepage rates (and correspondingly less chemosynthesis based primary production). Crusts of seep carbonates account for the higher diversity of the seep site compared to the background site, since most animals were either colonizing crust surfaces or using them for shelter or coverage. Our results indicate that seeps in northern latitudes can enhance local benthic diversity and this effect can take place even with weak seepage. Since crusts of seep carbonates account for most of the aggregating effect of sites experiencing moderate/weak seepage such as the study site, this means that the ability of seep sites to attract benthic species extends well beyond the life cycle of the seep itself, which has important implications for the larger marine ecosystem and its management policies.
A study on the eye movement in people with low vision ‐ A case study in an eye clinic
Authors: Matsuda Yuji , Hara Toshiaki , Kashiwase Mitsutoshi , Nishide Kazuhiko 
Published: August 2019

AbstractEight people with low vision and eight people with no visual disability, each equipped with an eye‐mark recorder, were made to walk around the interior of an eye clinic in order to study the walking behavior and eye‐fixation behavior of people with low vision. Their actions and eye marks were recorded on video and their walking speeds and eye movements were compared. The results are as follows: (i) People with low vision tend to walk more slowly, directing their vision in many directions. (ii) People with low vision tend to look at the floor more, in particular, at the edges of the floor. (iii) People with no visual disability look at the target objects and use their peripheral vision while they walk, while people with low vision look more at the elements in their immediate environment while they walk. (iv) Environments with high contrast and continuous boundary surfaces that indicate walking directions are effective in making an interior environment easier for people with low vision to walk in. (v) For people with narrow visual fields or low visual acuity, composing the boundary surface so that it has a certain width increases the effectiveness of perception.
Circularly Polarized Luminescence in Nanoassemblies: Generation, Amplification, and Application
Authors: Sang Yutao , Han Jianlei , Zhao Tonghan , Duan Pengfei , Liu Minghua 
Published: August 2019

AbstractCurrently, the development of circularly polarized luminescent (CPL) materials has drawn extensive attention due to the numerous potential applications in optical data storage, displays, backlights in 3D displays, and so on. While the fabrication of CPL‐active materials generally requires chiral luminescent molecules, the introduction of the “self‐assembly” concept offers a new perspective in obtaining the CPL‐active materials. Following this approach, various self‐assembled materials, including organic‐, inorganic‐, and hybrid systems can be endowed with CPL properties. Benefiting from the advantages of self‐assembly, not only chiral molecules, but also achiral species, as well as inorganic nanoparticles have potential to be self‐assembled into chiral nanoassemblies showing CPL activity. In addition, the dissymmetry factor, an important parameter of CPL materials, can be enhanced through various pathways of self‐assembly. Here, the present status and progress of self‐assembled nanomaterials with CPL activity are reviewed. An overview of the key factors in regulating chiral emission materials at the supramolecular level will largely boost their application in multidisciplinary fields.
