The mass compressibility of composition low-cement corundum castable with an addition of chromium oxide, depending on its moisture (2.5, 3.0, 3.5, 4.0, 4.5 %) and specific pressing pressure (50, 75, 100 N/mm2) has been investigated. The optimum moisture of the forming mass (3.0—3.5 %) and the pressing pressure (100 N/mm2), which ensure the production of fresh-formed samples with an apparent density of 3.14 g/cm3, dried (after hardening in humid conditions for 7 days ) with an apparent density of 3.03—3.04 g/cm3, and fired samples with an apparent density, open porosity and compressive strength, respectively, of 2.97—2.98 g/cm3, 24.8—25.0 %, 80—83 N/mm2, were established. The obtained research results can be used at the enterprises producing carbon black for the products manufacture by semidry pressing or ramming methods from the delivered by PJSC “UKRNIIO NAMED AFTER A. S. BEREZHNOY” dry mixtures containing all the necessary mass components. The products ramming, as well as pressing, must be carried out up to obtain an apparent density of fresh-formed green not less than 3.14 g/cm3.

Published: August 2019

Objetivo: describir la frecuencia de las lesiones dermatológicas en pacientes de la Unidad de Cuidados Intensivos (UCI) de adultos del Hospital de San José y del Hospital Infantil Universitario de San José entre enero y abril de 2012.
Pacientes y métodos: se realizó un estudio descriptivo de corte transversal. Se incluyeron pacientes mayores de 18 años con estancia mínima de 72 horas en UCI, ingresados por patología dermatológica o valorados por dermatología por aparición de lesiones en piel durante su estancia.
Resultados: se evaluaron 595 pacientes, encontrando lesiones dermatológicas en 30% (182 pacientes). La edad promedio fue de 63.5 años ± 19.1 sin diferencias de género. La admisión a la UCI se debió principalmente a motivos no quirúrgicos con un porcentaje de 57.3% (105 pacientes). Las lesiones cutáneas más frecuentes fueron las lesiones terciarias observada en 91.8% (168 pacientes), seguida por lesiones secundarias, con predominio infeccioso 6% (11 pacientes) y las últimas fueron las primarias con sólo 1.6% (3 pacientes).
Conclusiones: las lesiones dermatológicas en los pacientes de UCI son más frecuentes de lo esperado y en algunos casos pueden ser la causa directa del ingreso a la UCI poniendo en riesgo la vida de los pacientes, por lo tanto, consideramos importante un examen exhaustivo de piel en estos pacientes y el trabajo interdisciplinario con dermatología que permita disminuir el riesgo de mortalidad a causa de complicaciones de origen dermatológico.
Precise local control of liquid crystal pretilt on polymer layers by focused ion beam nanopatterning
Authors: Gorkunov Maxim V , Kasyanova Irina V , Artemov Vladimir V , Mamonova Alena V , Palto Serguei P 
Published: August 2019

Background: The alignment of liquid crystals by surfaces is crucial for applications. It determines the director configuration in the bulk, its stability against defects and electro-optical switching scenarios. The conventional planar alignment of rubbed polymer layers can be locally flipped to vertical by irradiation with a focused ion beam on a scale of tens of nanometers.Results: We propose a digital method to precisely steer the liquid crystal director tilt at polymer surfaces by combining micrometer-size areas treated with focused ion beam and pristine areas. The liquid crystal tends to average the competing vertical and planar alignment actions and is stabilized with an intermediate pretilt angle determined by the local pattern duty factor. In particular, we create micrometer-sized periodic stripe patterns with this factor gradually varying from 0 to 1. Our optical studies confirm a predictable alignment of a nematic liquid crystal with the pretilt angle continuously changing from 0° to 90°. A one-constant model neglecting the difference between the elastic moduli reproduces the results quantitatively correctly.Conclusion: The possibility of nanofabrication of polymer substrates supporting an arbitrary (from planar to vertical) spatially inhomogeneous liquid crystal alignment opens up prospects of “imprinting” electrically tunable versatile metasurfaces constituting lenses, prisms and q-plates.
Saha Ionization Equation in the Early Universe
Authors: Das Aritra , Ghosh Ritesh , Mallik S. 
Published: August 2019

Abstract
The Saha equation follows from thermal equilibrium of matter and radiation. We discuss this problem of equilibrium in the early universe, when matter consists mostly of electrons, protons, and hydrogen atoms. Taking H atoms in their ground state only and applying the real-time formulation of thermal field theory, we calculate the difference of ionization and recombination rates, which controls the equilibration of H atoms. By comparing with realistic calculations including the excited states of the H atom, we conclude that the presence of excited states lowers the equilibrium temperature from 5000 to 4000 K.
Smoothing of MHD Shocks in Mode Conversion
Authors: Pennicott Jamon D. , Cally Paul S. 
Published: August 2019

Abstract
Shock waves are simulated passing through the Alfvén-acoustic equipartition layer in a stratified isothermal magneto-atmosphere. The recent ray-theoretic calculations of Núñez predicted smoothing of the shock through this layer, causing both the fast and slow components to emerge as continuous waves. However, it is found that the partial mode conversion expected from linear theory for oblique incidence of the shock on the magnetic field is accompanied by a smoothing of the slow shock only, while the fast shock persists. Explanations are presented based on magnetohydrodynamic mode conversion and shock theory.
Reconnection Front Associated with Asymmetric Magnetic Reconnection: Particle-in-cell Simulations
Authors: Song Liangjin , Zhou Meng , Yi Yongyuan , Deng Xiaohua , Zhong Zhihong 
Published: August 2019

Abstract
Reconnection front (RF) has frequently been observed in the magnetotail and is well known as the dipolarization front in the near-Earth tail. Whether the RF exists in reconnection with distinct plasma/field properties across the reconnecting current sheet (i.e., asymmetric reconnection) is unknown yet. In this Letter, we use 2.5D particle-in-cell simulations to investigate the properties of RF in asymmetric reconnection and compare to RFs in symmetric reconnection. We find that RF is a robust structure in asymmetric reconnection. Its moving speed and thickness are smaller than those in symmetric reconnection. Its properties, such as the current density, electromagnetic field structure, are examined. Some features of RF in asymmetric reconnection are drastically different than those in symmetric reconnection. These results are of great help for studying RF in plasma environments with asymmetric reconnection, such as Earth’s magnetopause.

Published: August 2019

Abstract
Behçet disease is a chronic, relapsing-remitting autoinflammatory syndrome with a strong HLA-B*51 association. In this paper, we describe a human cohort of 267 individuals with Behçet disease and 445 matched controls from a tertiary referral center in the U.K. HLA-B*51 was confirmed as a genetic risk factor in this group (p = 0.0006, Bonferroni–Dunn correction for multiple testing [Pc] = 0.0192, odds ratio [OR] 1.92, 95% confidence interval [CI] 1.33–2.76). KIR3DL1/S1 allele-level analysis indicated that low-expressing KIR3DL1/S1 alleles in combination with KIR3DS1 increased the risk of developing Behçet disease (KIR3DL1LOW/KIR3DS1: p = 0.0004, Pc = 0.0040, OR 2.47, 95% CI 1.43–4.25), whereas high-expressing KIR3DL1/S1 alleles in combination with a null-expressing KIR3DL1 reduced the risk of disease (KIR3DL1HIGH/KIR3DL1NULL: p = 0.0035, Pc = 0.0350, OR 0.53, 95% CI 0.33–0.87). Behçet disease can manifest as a purely mucocutaneous disease or can involve other organ systems such as the eyes. In the U.K. cohort studied in this study, KIR3DL1LOW/KIR3DS1 increased the risk of ophthalmic disease (p = 1.2 × 10−5, OR 3.92, 95% CI 2.06–7.47), whereas KIR3DL1HIGH/KIR3DL1NULL reduced the risk of having purely mucocutaneous disease (p = 0.0048, OR 0.45, 95% CI 0.25–0.81). To our knowledge, this is the first analysis of KIR3DL1/S1 allelic variation in Behçet disease and may provide insight into the pathogenic role of HLA-B*51 and its interaction with KIR3DL1/S1.
Sphenochoanal polyp: Radiological diagnosis
Authors: Pak M. W. , Kew J. 
Published: August 2019

A sphenochoanal polyp is seen as an isolated soft tissue density mass that arises from the sphenoid sinus and extends to the choana on computed tomographic scans. Distinction from its more common counterpart, antrochoanal polyp which arises from the maxillary sinus, is essential prior to surgery. A case is presented to illustrate that CT scan of paranasal sinus plays an important role in the identification of the sinus of origin.
Speciated atmospheric mercury and sea–air exchange of gaseous mercury in the South China Sea
Authors: Wang Chunjie , Wang Zhangwei , Hui Fan , Zhang Xiaoshan 
Published: August 2019

Abstract. The characteristics of the reactive gaseous mercury (RGM) and particulate
mercury (HgP) in the marine boundary layer (MBL) are poorly understood,
due in part to sparse data from the sea and ocean. Gaseous elemental Hg (GEM),
RGM, and size-fractionated HgP in the marine atmosphere, and dissolved gaseous
Hg (DGM) in surface seawater, were determined in the South China Sea (SCS)
during an oceanographic expedition (3–28 September 2015). The mean
concentrations of GEM, RGM, and Hg2.5P were 1.52±0.32 ng m−3, 6.1±5.8 pg m−3, and 3.2±1.8 pg m−3,
respectively. A low GEM level indicated that the SCS suffered less influence
from fresh emissions, which could be due to the majority of air masses
coming from the open oceans, as modeled by back trajectories. Atmospheric
reactive Hg (RGM + Hg2.5P) represented less than 1 % of total
atmospheric Hg, indicating that atmospheric Hg existed mainly as GEM in the
MBL. The GEM and RGM concentrations in the northern SCS (1.73±0.40 ng m−3 and 7.1±1.4 pg m−3, respectively) were
significantly higher than those in the western SCS (1.41±0.26 ng m−3 and 3.8±0.7 pg m−3), and the Hg2.5P and
Hg10P levels (8.3 and 24.4 pg m−3) in the Pearl River estuary
(PRE) were 0.5–6.0 times higher than those in the open waters of the SCS,
suggesting that the PRE was polluted to some extent. The size distribution
of HgP in PM10 was observed to be three-modal, with peaks around
< 0.4, 0.7–1.1, and 5.8–9.0 µm, respectively, but the
coarse modal was the dominant size, especially in the open SCS. There was no
significant diurnal pattern of GEM and Hg2.5P, but we found that the
mean RGM concentration was significantly higher in daytime (8.0±5.5 pg m−3) than in nighttime (2.2±2.7 pg m−3), mainly due to
the influence of solar radiation. In the northern SCS, the DGM
concentrations in the nearshore area (40–55 pg L−1) were about twice as
high as those in the open sea, but this pattern was not significant in the
western SCS. The sea–air exchange fluxes of Hg0 in the SCS varied from
0.40 to 12.71 ng m−2 h−1 with a mean value of 4.99±3.32 ng m−2 h−1. The annual emission flux of Hg0 from the SCS to the
atmosphere was estimated to be 159.6 t yr−1, accounting for about
5.54 % of the global Hg0 oceanic evasion, although the SCS only
represents 1.0 % of the global ocean area. Additionally, the annual dry
deposition flux of atmospheric reactive Hg represented more than 18 % of
the annual evasion flux of Hg0, and therefore the dry deposition of
atmospheric reactive Hg was an important pathway for the input of
atmospheric Hg to the SCS.
ORCHIDEE MICT-LEAK (r5459), a global model for the production, transport, and transformation of dissolved organic carbon from Arctic permafrost regions – Part 1: Rationale, model description, and simulation protocol

Published: August 2019

Abstract. Few Earth system models adequately represent the unique permafrost soil
biogeochemistry and its respective processes; this significantly contributes
to uncertainty in estimating their responses, and that of the planet at
large, to warming. Likewise, the riverine component of what is known as the
“boundless carbon cycle” is seldom recognised in Earth system modelling.
The hydrological mobilisation of organic material from a ∼1330–1580 PgC carbon stock to the river network results in either
sedimentary settling or atmospheric “evasion”, processes widely expected to
increase with amplified Arctic climate warming. Here, the production,
transport, and atmospheric release of dissolved organic carbon (DOC) from
high-latitude permafrost soils into inland waters and the ocean are
explicitly represented for the first time in the land surface component
(ORCHIDEE) of a CMIP6 global climate model (Institut Pierre Simon Laplace – IPSL). The model, ORCHIDEE MICT-LEAK, which represents the merger of
previously described ORCHIDEE versions MICT and LEAK, mechanistically
represents (a) vegetation and soil physical processes for high-latitude
snow, ice, and soil phenomena and (b) the cycling of DOC and CO2,
including atmospheric evasion, along the terrestrial–aquatic continuum from
soils through the river network to the coast at 0.5 to
2∘ resolution. This paper, the first in a two-part study,
presents the rationale for including these processes in a high-latitude-specific land surface model, then describes the model with a focus on novel
process implementations, followed by a summary of the model configuration
and simulation protocol. The results of these simulation runs, conducted for
the Lena River basin, are evaluated against observational data in the second
part of this study.

Determinar la prevalencia de obesidad, sobrepeso y desnutrición en estudiantes de la Facultad de Ciencias Sociales de la Universidad Evangélica de El Salvador. Esta investigación cuantitativa, transversal y de tipo descriptivo, se realizó en el 2009 en la Facultad de Ciencias Sociales de la UEES y se evaluaron 293 estudiantes. Las variables estudiadas incluyeron edad, genero, índice de masa corporal, actividad física, hábitos alimentarios, compromiso sistémico e hidratación. El 68.6% eran de género femenino y el 31.4% de género masculino, con edades entre 21 y 23 años. La prevalencia para desnutrición fue del 23.89%, 13.32% para sobrepeso leve, 9.57% para sobrepeso moderado, 5.8 % para obesidad, 4.79% para obesidad mórbida y un 42.66% de los estudiantes presentaron un índice de masa corporal normal. El 42.66% de los estudiantes evaluados presenta un índice de masa corporal normal; pero en su conjunto el 57.34% de los estudiantes están mal-nutridos siendo la sobre-nutrición (33.48%) el problema más grave seguido de la desnutrición (23.89%); lo que sugiere la ampliación de este estudio incluyendo a estudiantes de todas las carreras para la futura implementación de programas de orientación nutricional y prácticas de actividad física supervisada.
Seismic assessment and improvement of unreinforced stone masonry buildings
Authors: Giaretton Marta , Dizhur Dmytro , Da Porto Francesca , Ingham Jason M. 
Published: August 2019

Following the 2010/2011 Canterbury earthquakes considerable effort was applied to the task of developing industry guidance for the seismic assessment, repair and strengthening of unreinforced masonry buildings. The recently updated “Section 10” of NZSEE 2006 is one of the primary outputs from these efforts, in which a minor amount of information is introduced regarding vintage stone unreinforced masonry (URM) buildings. Further information is presented herein to extend the resources readily available to New Zealand practitioners regarding load-bearing stone URM buildings via a literature review of the traditional European approach to this topic and its applicability to the New Zealand stone URM building stock.
An informative background to typical stone URM construction is presented, including population, geometric, structural and material characteristics. The European seismic vulnerability assessment procedure is then reported, explaining each step in sequence of assessment by means of preliminary inspection (photographic, geometric, structural and crack pattern surveys) and investigation techniques, concluding with details of seismic improvement interventions. The challenge in selecting the appropriate intervention for each existing URM structure is associated with reconciling the differences between heritage conservation and engineering perspectives to reinstating the original structural strength. Traditional and modern techniques are discussed herein with the goal of preserving heritage values and ensuring occupant safety. A collection of Annexes are provided that summarise the presented information in terms of on-site testing, failure mechanisms and seismic improvement.
