Assessing the Impact of Cyanuric Acid on Bather’s Risk of Gastrointestinal Illness at Swimming Pools
Authors: Falk Richard A. , Blatchley Ernest R. , Kuechler Thomas C. , Meyer Ellen M. , Pickens Stanley R. , Suppes Laura M.
Published: June 2019

Current regulatory codes for swimming pool disinfection separately regulate free chlorine (FC) and cyanuric acid (CYA). It is well-known that CYA affects disinfection rates by reversibly binding to FC in aqueous solutions. However, limits for these regulated parameters have neither systematically accounted for this chemistry nor been based on the risk of gastrointestinal illness. This study was intended to determine the minimum concentration of FC relative to CYA based on the risk of gastrointestinal illness from normal fecal sloughing of selected pathogens and to find a simple regulatory rule for jointly managing FC and CYA for consistent disinfection. Literature data on CYA’s effect on microbial inactivation rates were reanalyzed based on the equilibria governing hypochlorous acid (HOCl) concentration. A model was developed that considers the rates of pathogen introduction into pool water, disinfection, turbulent diffusive transport, and pathogen uptake by swimmers to calculate the associated risk of illness. Model results were compared to U.S. Environmental Protection Agency (EPA) untreated recreational water acceptable gastrointestinal illness risk. For Cryptosporidium, correlation between log inactivation and Chick–Watson Ct was far better when C refers to HOCl concentration than to FC (r = −0.96 vs. −0.06). The HOCl concentration had a small variation (± 1.8%) at a constant CYA/FC ratio for typical FC and CYA ranges in swimming pools. In 27 U.S. states, the allowed FC and CYA results in HOCl concentrations spanning more than a factor of 500. Using conservative values for a high bather load pool with 2 mg/L FC and 90 mg/L CYA, the model predicted a 0.071 annual probability of infection for Giardia, exceeding the EPA regulatory 0.036 limit for untreated recreational waters. FC and CYA concentrations in swimming pools should be jointly regulated as a ratio. We recommend a maximum CYA/FC ratio of 20.

Practical application of thermal analysis in the development and study of polymer composites
Authors: Antyufeeva, N. V. , Slavin A. V. , Bolshakov V. A.
Published: June 2019

Modern multifunctional thermoanalytical complexes equipped with computers are inherently mobile laboratories. They are able to solve a wide variety of problems in materials science and technology, both in applied research and in the quality control of products supplied to manufacturing enterprises. Using the example of experimental data obtained in the study of the curing processes of thermosetting semi-finished products (prepregs) of polymer composite materials (PCM), the methodological possibilities of modern devices for thermal analysis are shown. They allow investigating and predicting changes in the technological properties of prepregs in a wide temperature range.
The effect of granules of FPS-S polystyrene on the properties of PPU-240-2 rigid PU foam
Authors: Pasechnik M. P. , Dorofeev A. A.
Published: June 2019

The effect of FPS-S polystyrene granules on the properties of PPU-240-2 polyurethane foam was investigated. It is shown that addition of FPS-S in the composition of PPU-240-2 reduces the temperature that develops during foaming and increases the density of the material. Replacing part of the FPS-S granules with partially foamed ones leads to a more uniform distribution of the granules over the surface of the foam.
Da decodificação ao projeto de leiturização: perspectivas para o ensino de leitura nas escolas
Authors: Sampaio Fernando Alisson Santos , Borges da Silva Simone Bueno
Published: June 2019

Nos dias atuais, muitos estudos no campo dos Letramentos têm se debruçado sobre a divisão social das técnicas de uso da escrita, cujo efeito, numa sociedade hierarquizada e estratificada, desvela e aponta, consequentemente, para uma distribuição desigual das técnicas de acesso aos bens simbólicos, assim como reforça os traços excludentes da população brasileira. Entre os aspectos que corroboram para este cenário está uma proposta de ensino de leitura com foco na Alfabetização, desprezando, assim, as dimensões sociais e políticas do ato de ler. A partir disso, formamos muitos alfabetizados e poucos letrados. Em consequência, há a expansão do iletrismo, caracterizando-se pela exclusão das condições que permitam aos estudantes participarem das redes de circulação de impressos. Nesse sentido, neste trabalho, por meio de uma revisão de literatura (FREIRE, 1989; KLEIMAN, 1995; 2000; 2004; ROJO, 2009; STREET, 2014), tenho como objetivo defender uma concepção de formação em leitura não mais centrada no alfabetizado, mas sim no leitor, a partir de um Projeto de Leiturização (FOUCAMBERT, 1994). Ademais, apresento possibilidades de trabalho com a leitura de um modo mais efetivo e democrático. Os resultados apontam que um processo formativo pautado nos usos sociais da escrita e da leitura contribuem significativamente para a formação de leitores críticos, bem como de pessoas mais preparadas para o enfrentamento dos entraves de sua comunidade.

Published: June 2019

Objective - Caregiving of a child with special needs can increase the cost of raising the child and parent’s stress. These two issues are commonly experienced by a parent who care for their special needs child themselves and the thought of challenges are different based on the disability of the child. Methodology/Technique – The challenges of raising a child with disability make it necessary for parents to work harder to to meet the cost of treatment. Meanwhile, levels of stress among those parents are understandably increased. Finding – Parents caring for a child with disability need to place greater emphasis on achieving a balance between their work, caring for their child and stress. Further, this paper includes a discussion on the cost of raising a disabled child and the increased levels of stress experienced by these parents. Novelty - The findings of this paper contribute to conceptual model on the challenges faced by Malaysian parents in caregiving for a child with special needs. Type of Paper: Review
Intermediary Effect of Intention of ICT adoption on the Relationship of Attitudes toward Adoption and Adoption of VLE among the Malay Language Teachers
Authors: Peng Chew Fong , Hamid Zanariah , Nizam Mohd. Shahril
Published: June 2019

Objective - This research aims to explore whether the intention of ICT adoption in teaching Malay language acts as a mediator in the relationship between attitudes toward ICT adoption and the adoption of the Virtual Learning Environment (VLE) among secondary school Malay Language teachers.
Methodology/Technique – TAM is the basis theory in this quantitative study which uses a questionnaire to collect the data. The population of the study comprises of 410 secondary school teachers in Selangor by applying various probability sampling procedures. The research instrument was adapted from a previous questionnaire and pilot study which shows an alpha Cronbach at .81. Software of Smart-PLS was used to analyse the results of the study.
Findings - The mediator analysis showed a positive and significant direct relationship (β = .067, p <.05) between attitude and the adoption of VLE. The findings obtained in the analysis of indirect relationships and direct relationships clearly indicate that the intention of ICT adoption acts as partial mediator if the impression of indirect contact with the effects of direct relationships was significant.
Novelty - In summary, the significant relationship between attitudes toward adoption and the intention of ICT adoption and adoption of VLE suggest that intention acts as a mediator.

Access to Information of Disabled People on the Web: A Dispute between Accessibility and Digital Rights Management
Authors: Lamlert Wariya , Sawetrattanasatian Oranuch
Published: June 2019

Objective - The study aims to explore the dispute between accessibility and Digital Rights Management (DRM) for disabled people in accessing information on the Web. More specifically, this paper explores the challenges DRM has placed on them.
Methodology/Technique –This study inspects the controversial interaction between accessibility and DRM in relation to disabled people’s access to information on the Web using document analysis from a socio-legal perspective. Further, the black-letter law of some widely known and internationally cited regulations are used in the investigation and discussion.
Findings & Novelty- It is argued that the regulations which are beneficial to the accessibility of disabled people are overruled by DRM. More specifically, the challenges posed by DRM include: (1) Negligence of disabled people’s rights, (2) Conflict of accessibility, and (3) Ignorance of copyright-related exceptions. This study is a cross disciplinary study probing the issue of disabled people in both legal studies, through relevant legislation, and information studies, through the topic of information access on the Web. It examines and analyses major regulations issued by leading organizations across the two disciplines. The findings of this study may be beneficial to knowledge and practice to bridge the gap of human rights for information access, particularly for disabled people, and argues that both information and legal professionals should be responsible for this.

Multi-epoch Low-radio-frequency Surveys of the Kepler K2 Mission Campaign Fields 3, 4, and 5 with the Murchison Widefield Array
Authors: Tingay S. J. , Hancock P. J.
Published: June 2019

We present Murchison Widefield Array (MWA) monitoring of the Kepler K2 mission fields 3, 4, and 5 at frequencies of 155 and 186 MHz, from observations contemporaneous with the K2 observations. This work follows from previous MWA and Giant Metrewave Radio Telescope (GMRT) surveys of field 1, with the current work benefiting from a range of improvements in the data processing and analysis. We continue to build a body of systematic low-frequency blind surveys overlapping with transient/variable survey fields at other wavelengths, providing multiwavelength data for object classes such as flare stars. From the current work, we detect no variable objects at a surface density above 2 × 10−4 per square degree, at flux densities of ∼500 mJy, and an observation cadence of days to weeks, representing almost an order of magnitude decrease in the measured upper limits compared to previous results in this part of observational parameter space. This continues to show that radio transients at meter and centimeter wavelengths are rare.
The Coevolution of Massive Quiescent Galaxies and Their Dark Matter Halos over the Last 6 Billion Years
Authors: Zahid H. Jabran , Geller Margaret J. , Damjanov Ivana , Sohn Jubee
Published: June 2019

We investigate the growth of massive quiescent galaxies at z < 0.6 based on the Sloan Digital Sky Survey and the Smithsonian Hectospec Lensing Survey, two magnitude-limited spectroscopic surveys of high data quality and completeness. Our three-parameter model links quiescent galaxies across cosmic time by self-consistently evolving stellar mass, stellar population age-sensitive D

n
4000 index, half-light radius, and stellar velocity dispersion. Stellar velocity dispersion is a robust proxy of dark matter halo mass; we use it to connect galaxies and dark matter halos and thus empirically constrain their coevolution. The typical rate of stellar mass growth is

, and dark matter growth rates from our empirical model are remarkably consistent with N-body simulations. Massive quiescent galaxies grow by minor mergers with dark matter halos of mass

and evolve parallel to the stellar mass–halo mass (SMHM) relation based on N-body simulations. Thus, the SMHM relation of massive galaxies apparently results primarily from dry minor merging.

Les représentations d’attachement, les relations d’objet et le jeu des enfants victimes de mauvais traitements
Authors: Paquette Mélissa , Terradas Miguel M. , Chazan Saralea E. , Lepage-Voyer Cécilanne , Guillemette Rosalie
Published: June 2019

Les auteurs de cette étude visent à décrire les représentations d’attachement, les relations d’objet, ainsi que le jeu de quinze enfants d’âge scolaire, ayant vécu des traumas relationnels précoces, à l’aide de deux situations de jeu, l’une structurée et l’autre libre. Deux instruments, les histoires d’attachement à compléter et le Children’s Play Therapy Instrument , ont permis d’analyser les représentations de l’enfant. Les résultats obtenus suggèrent que ces enfants ont des représentations soutenantes et non-rejetantes de leurs figures parentales, alors que leurs représentations des relations d’objet tendent à être plus immatures que matures. Toutefois, cette différence n’atteint pas le seuil de significativité statistique.
Adaptation socio-affective des enfants âgés de 9 à 12 ans et utilisation d’Internet au domicile
Authors: Berdot-Talmier Laurence , Zaouche-Gaudron Chantal
Published: June 2019

La plupart des enfants français ont, maintenant, accès aux technologies numériques de l’information et de la communication (TNIC) à leur domicile. En s’appuyant sur le modèle écosystémique de Bronfenbrenner (1979, 1986), les auteurs de cette recherche visent à saisir l’influence des environnements – utilisation d’Internet au domicile (sous-système technologique ; Johnson, 2010a) et caractéristiques socio-économiques (environnement microsystémique) – sur le développement socio-affectif des enfants (ontosystème), en fonction du sexe. Des questionnaires ont été administrés à 498 enfants (244 garçons et 254 filles) âgés de 9 à 12 ans et à leurs parents. Les indices d’utilisation d’Internet au domicile expliquent une part un peu plus importante des variations des scores de l’adaptation socio-affective des enfants que ceux relatifs aux caractéristiques socio-économiques des parents.
Henri Piéron (1881-1964) disciple d’Édouard Toulouse (1865-1947)
Authors: Huteau Michel
Published: June 2019

Henri Piéron commence sa carrière scientifique au laboratoire d’Édouard Toulouse en 1900. Il devient vite son principal collaborateur. Piéron quittera ce laboratoire en 1912, mais il restera proche de Toulouse. Ils ont les mêmes conceptions épistémologiques – ce sont des positivistes scientistes – et politiques – ce sont des républicains qui placent l’égalité au premier plan de leurs valeurs. L’examen des lettres de Toulouse adressées à Piéron témoigne de leur proximité. Piéron a joué un rôle actif dans le développement de l’orientation professionnelle en France. Son projet est identique à celui de Toulouse : l’orientation professionnelle doit être fondée sur le diagnostic d’aptitudes héréditaires. Les pratiques qui se sont mises en place par la suite en sont éloignées.
Le soin aux disparus
Authors: Verburgt Jessica , Caron Rosa
Published: June 2019

Les services funéraires sont de plus en plus sollicités pour prendre soin des disparus et leur redonner vie et corps. Les mouvements psychiques qui accompagnent ces soins ont longtemps été déniés voire occultés. Pourtant il ne fait pas de doute que la rencontre avec le cadavre mobilise chez ceux qui y sont confrontés une dynamique subjective dont la logique est régie par l’émergence d’un monde fantasmatique propre à chacun. Les auteurs proposent d’explorer à partir d’une écoute clinique les enjeux de cette dynamique et le vécu de ces professionnels qui restent souvent livrés à leur propre solitude.
Le linceul, accompagner et envelopper une dernière fois les disparus
Authors: van den Eerenbeemt-Penant Sharon
Published: June 2019

L’auteure partage ses expériences d’accompagnatrice dans le cadre d’un atelier créatif d’accompagnement de deuil, ou elle a choisi de proposer de faire un linceul, une enveloppe symbolique sous la forme du dernier habit pour accompagner le défunt. Dans sa plus simple expression, on pourrait dire que la création voire la créativité est l’aptitude à concevoir et à vivre une réalité autrement. L’homme s’exprime depuis la nuit des temps par ses mains. Faire son deuil, créer une trace, faire un objet symbolique de ses mains, dans un temps ritualisé en soi, toutes ces actions sont remarquablement présentes dans toutes les civilisations. Puisque nous sommes au moment de « faire », en lien avec notre histoire singulière avec le défunt, le linceul permet d’habiller, accompagner, protéger le disparu. Il permet aussi de vivre ce moment de lien symbolique, seul ou en le partageant avec le groupe familial, amical. Il permet aussi de s’approprier le moment des obsèques plus intimement, le cercueil n’est plus seulement un cercueil. Le cercueil permet de porter le linceul créé par les siens pour vêtir le défunt une dernière fois.
Typologie lexicale comparée des langues romanes : les spécificités de la langue française et leur implication sur la cognition et la culture
Authors: Begioni Louis , Rocchetti Alvaro
Published: June 2019

L’article étudie la manière dont les mots se construisent en français : ils deviennent de plus en plus compacts et aboutissent fréquemment à des monosyllabes. Le mot écrit se comporte comme un idéogramme et son correspondant oral tend à devenir un idéophone morphologiquement inanalysable. Le verbe perd progressivement la désinence personnelle, ce qui tend à rendre plus abstrait le lien entre son signifiant et son signifié. Le rapport existant dans les langues endocentriques entre le verbe et le nom s’est reporté en français, devenu typologiquement exocentrique, sur l’opposition entre un lexique construit allégé et une syntaxe plus développée et soumise à des règles de fonctionnement logique plus strictes.
Représentation d’un événement spatial, entre contraintes langagières et invariants typologiques
Authors: Vittrant Alice
Published: June 2019

En tant que système linguistique, la langue contraint l’expression d’un événement en conditionnant sa forme indépendamment de la structure sémantique de l’événement. Notre expérience du monde exerce une seconde contrainte sur l’expression d’événements sémantiquement complexes. Par exemple, nos capacités cognitives sont sollicitées pour interpréter les relations (cohésion forte) entre composants sémantiques d’un événement, comme dans les déplacements d’entités, imposant parfois des réalisations morphosyntaxiques particulières. Un troisième facteur peut encore influencer l’expression d’un événement dans une langue, c’est sa représentation culturelle. En prenant l’exemple des événements de trajectoire complexe, nous tâcherons de mettre en évidence ce qui relève de la langue, de la cognition ou de la typologie, dans l’expression de ces événements.
Cognition, énaction, perculturation : vers une caractérisation du lexique anglais dans une perspective typologique
Authors: Bottineau Didier
Published: June 2019

Le lexique de l’anglais actuel présente des doublons lexicaux comme freedom et liberty , issus de la rencontre de langues germaniques et romanes lors de l’invasion normande de l’Angleterre saxonne et de contacts et emprunts ultérieurs. Dans la présente étude, on montre comment la collision de systèmes lexicaux issus de langues endo- et exocentriques, symboliques d’interactions verbales et de hiérarchisations intercommunautaires conflictuelles, a fini par former un système auto-organisé renouvelé où se joue le choix entre différentes mises en scènes de l’interaction et de la co-production du sens. Pour analyser le processus, on fait référence au paradigme de l’énaction en linguistique.

Published: June 2019

Numerous studies have investigated the use of waste glass as a partial substitution in Portland cement. Nonetheless, it seems there is no consensus about the influence of particle size and color on the behavior of the compounds. This work investigates the influence of soda-lime glass microparticles on the properties of cement and mortar in both fresh and hardened states. The effects of partial substitution (10 and 20%) of the cement by colorless and amber glass particles with dimensions of approximately 9.5 mm were investigated. The results revealed that the substitutions did not significantly affect the setting times, nor the mechanical properties of mortar at longer curing times. The influence of glass content and chemical composition on workability and hydration heat was also observed. The waste glass samples showed lower thermal diffusivity than the control sample. Thermal emissivity was not influenced by the presence of glass microparticles.
Alkali activated materials based on glass waste and slag for thermal and acoustic insulation
Authors: Stoleriu S. , Vlasceanu I. N. , Dima C. , Badanoiu A. I. , Voicu G.
Published: June 2019

Porous alkali activated materials (AAM), can be obtained from waste glass powder and slag mixtures by alkali activation with NaOH solution. To obtain an adequate porous microstructure, the hardened AAM pastes were thermally treated at temperatures ranging between 900°C and 1000°C, for 60 or 30 minutes. Due to the intumescent behaviour specific for this type of materials, an important increase of the volume and porosity occurs during the thermal treatment.

The partial substitution of waste glass powder with slag, determines the increase of compressive strength assessed before (up to 37 MPa) and after (around 10 MPa) thermal treatment; the increase of slag dosage also determines the increase of the activation temperature of the intumescent process (above 950°C).

The high porosity and the specific microstructure (closed pores with various shapes and sizes) of these materials recommend them to be utilised as thermal and acoustical insulation materials.
Concurrent Juvenile Myelomonocytic Leukemia with Thalassemia in a Case with Plasmodium knowlesi Infection from Sabah, Malaysian Borneo

Published: June 2019

A 3-year-old male child was presented with worsening abdominal pain, abdominal distension, lethargy, pallor and hepatosplenomegaly. The patient had multiple outpatient visits in the past and was treated with oral antibiotics, oral anthelmintic agents, albeit with minimal benefit. The patient also had non-neutropenic pyrexia spikes and oral ulcers. The patient was an adopted child; hence details about his biological parents’ previous history were unclear. Differential diagnosis of Chronic Myelomonocytic Leukemia (CMML), Juvenile Myelomonocytic Leukemia (JMML), Gaucher’s disease, Thalassemia and discrete pancreatic pathology was considered. Hemoglobin electrophoresis was indicative of thalassemia. Also, molecular detection method by polymerase chain reaction confirms a concurrent infection with Plasmodium knowlesi malaria. The BCR-ABL fusion gene was found to be negative. Correlating with peripheral monocytosis, bone marrow aspiration and trephine biopsy with blasts only 3–4% and hepatosplenomegaly, a diagnosis of JMML was established. We present a rare phenomenon with an overlap of signs and symptoms between JMML, underlying thalassemia, and Plasmodium knowlesi, posing a diagnostic challenge to physicians.

Additive and Nonadditive Effects of Salmon Calcitonin and Omega-3 Fatty Acids on Antioxidant, Hematological and Bone and Cartilage Markers in Experimental Diabetic-Osteoarthritic Rats
Authors: Adeyemi Wale J. , Olayaki Luqman A.
Published: June 2019

Reports on the coexistence of diabetes mellitus and osteoarthritis in human subjects dated back to the 1960s. However, there is no account in literature on the co-manifestation of these disease conditions in experimental animals. In our previous study, we reported for the first time, the effects of pharmacological agents on glucoregulatory indices, lipid profile, and inflammatory markers in experimental diabetic-knee osteoarthritic rat. However, in the present study, the effects of salmon calcitonin (Sct), and/or omega-3 fatty acids (N-3) were further investigated on other biomarkers. Forty-nine rats of seven animals per group were used for this study. Diabetes was induced by the administration of streptozotocin (65 mg/kg) and nicotinamide (110 mg/kg). Thereafter, knee osteoarthritis was induced by the intra-articular injection of 4 mg of sodium monoiodoacetate in 40 μl of saline. Nine days after the inductions, treatments started, and they lasted for 4 weeks. N-3 was administered at 200 mg/kg/day, while Sct was administered at 2.5 and 5.0 IU/kg/day. The results of the study indicated that the induced diabetes-knee osteoarthritis caused significant alterations in all the observed biomarkers. Sct showed a dose-specific effect and an additive action with N-3 in reducing malondialdehyde and lactate dehydrogenase, and in elevating total bilirubin and total antioxidant capacity. However, it largely demonstrated a nondose-specific effect and nonadditive action with N-3 on superoxide dismutase, catalase, glutathione peroxidase, total alkaline phosphatase, c-telopeptide of type-I collagen, collagen type-2 alpha 1, and hematological indices. In conclusion, the combined administration of Sct and N-3 proffer better therapeutic effects than the single therapy; therefore, they could be used in the management of diabetic-osteoarthritic condition.

Molecular epidemiological data are key for dengue outbreak characterization and preparedness. However, sparse Dengue virus (DENV) molecular information is available in Laos because of limited resources. In this proof-of-concept study, we evaluated whether DENV1 RNA extracted from rapid diagnostic tests (RDTs) could be amplified and sequenced. The protocol for envelope gene amplification from RNA purified from RDTs was first assessed using viral isolate dilutions then conducted using 14 dengue patient sera. Envelope gene amplification was successful from patient sera with high virus titer, as was sequencing but with lower efficiency. Hence, based on our results, RDTs can be a source of DENV1 RNA for subsequent envelope gene amplification and sequencing. This is a promising tool for collecting molecular epidemiology data from rural dengue-endemic areas. However, further investigations are needed to improve assay efficiency and to assess this tool’s level of efficacy on a larger scale in the field.
A Comparative Evaluation of Aura-OMI and SKYNET Near-UV Single-scattering Albedo Products
Authors: Jethva Hiren , Torres Omar
Published: June 2019

Abstract. The aerosol single-scattering albedo (SSA) retrieved by the near-UV algorithm applied to the Aura/Ozone Monitoring Instrument (OMI) measurements (OMAERUV) is compared with an independent inversion product derived from the sky radiometer network SKYNET-a ground-based radiation observation network span over Asia and Europe. The present work continues our efforts to evaluate the consistency between the retrieved SSA from satellite and ground sensors. The automated spectral measurements of direct downwelling solar flux and sky radiances made by SKYNET Sun-sky radiometer are used as input to an inversion algorithm that derives spectral aerosol optical depth (AOD) and single-scattering albedo (SSA) in the near-UV to near-IR spectral range. The availability of SKYNET SSA measurements in the ultraviolet region of the spectrum allows, for the first time, a direct comparison with OMI SSA retrievals eliminating the need of extrapolating the satellite retrievals to the visible wavelengths as the case in the evaluation against the Aerosol Robotic Network (AERONET). An analysis of the collocated retrievals from over 25 SKYNET sites reveals that about 61 % (84 %) of OMI-SKYNET matchups agree within the absolute difference of ± 0.03 (± 0.05) for carbonaceous aerosols, 50 % (72 %) for dust aerosols, 45 % (75 %) for urban-industrial aerosol types. Regionally, the agreement between the two inversion products was robust over several sites in Japan influenced by carbonaceous and urban-industrial aerosols, at the biomass burning site Phimai in Thailand, and polluted urban site in New Delhi, India. The collocated dataset yields fewer matchups identified as dust aerosols mostly over the site Dunhuang with more than half of the matchup points confined to within ± 0.03 limits. Combinedly, the OMI-SKYNET retrievals agree mostly within ± 0.03 for the AOD (388 or 400 nm) larger than 0.5 and UV Aerosol Index larger than 0.2. The remaining uncertainties in both inversion products can be attributed to specific assumptions made in the retrieval algorithms, i.e., the uncertain calibration constant, assumption of spectral surface albedo and particle shape, and sub-pixel cloud contamination. The assumption of fixed and spectrally neutral surface albedo (0.1) in the SKYNET inversion appears to be unrealistic, leading to a large underestimation of retrieved SSA, especially for low aerosol load conditions. At large AOD values for carbonaceous and dust aerosols, however, retrieved SSA values by the two independent inversion methods are generally consistent in spite of the differences in retrieval approaches.

Published: June 2019

Abstract. The rise of calcareous nannoplankton in Mesozoic oceans
has deeply impacted ocean chemistry and contributed to shaping modern oceans.
Nevertheless, the calcareous nannoplankton colonization of past marine
environments remains poorly understood. Based on an extensive compilation of
published and unpublished data, we show that their accumulation rates in
sediments increased from the Early Jurassic (∼200 Ma) to the
Early Cretaceous (∼120 Ma), although these algae diversified
up to the end of the Mesozoic (66 Ma). After the middle Eocene
(∼45 Ma), a decoupling occurred between accumulation rates,
diversity and coccolith size. The time series analyzed points toward a
three-phase evolutionary dynamic. An invasion phase of the open-ocean realms
was followed by a specialization phase occurring along with taxonomic
diversification, ended by an establishment phase where a few small-sized
species dominated. The current hegemony of calcareous nannoplankton in the
world ocean results from a long-term and complex evolutionary history shaped
by ecological interactions and abiotic forcing.
Flow velocity and discharge measurement in rivers using terrestrial and UAV imagery
Authors: Eltner Anette , Sardemann Hannes , Grundmann Jens
Published: June 2019

Abstract. An automatic workflow to measure surface flow velocities in rivers is introduced, including a Python tool. The method is based on PTV and comprises an automatic definition of the search area for particles to track. Tracking is performed in the original images. Only the final tracks are geo-referenced, intersecting the image observations with water surface in object space. Detected particles and corresponding feature tracks are filtered considering particle and flow characteristics to mitigate the impact of sun glare and outliers. The method can be applied to different perspectives, including terrestrial and aerial (i.e. UAV) imagery. To account for camera movements images can be co-registered in an automatic approach. In addition to velocity estimates, discharge is calculated using the surface velocities and wetted cross-section derived from surface models computed with structure-from-motion and multi-media photogrammetry. The workflow is tested at two river reaches (paved and natural) in Germany. Reference data is provided by ADCP measurements. At the paved river reach highest deviations of flow velocity and discharge reach 5 % and 4 %, respectively. At the natural river deviations are larger (up to 31 %) due to the irregular cross-section shapes hindering accurate contrasting of ADCP- and image-based results. The provided tool enables the measurement of surface flow velocities independently of the perspective from which images are acquired. With the contact-less measurement spatially distributed velocity fields can be estimated and river discharge in previously ungauged and unmeasured regions can be calculated.
Assessing the added value of the Intermediate Complexity Atmospheric Research (ICAR) model for precipitation in complex topography

Published: June 2019

Abstract. The coarse grid spacing of global circulation models necessitates the application of downscaling techniques to investigate the local impact of a changing global climate. Difficulties arise for data-sparse regions in complex topography, as they are computationally demanding for dynamic downscaling and often not suitable for statistical downscaling due to the lack of high-quality observational data. The Intermediate Complexity Atmospheric Research (ICAR) model is a physics-based model that can be applied without relying on measurements for training and is computationally more efficient than dynamic downscaling models. This study presents the first in-depth evaluation of multiyear precipitation time series generated with ICAR on a 4×4 km2 grid for the South Island of New Zealand for an 11-year period, ranging from 2007 to 2017. It focuses on complex topography and evaluates ICAR at 16 weather stations, 11 of which are situated in the Southern Alps between 700 and 2150mm.s.l (m m.s.l refers to meters above mean sea level). ICAR is assessed with standard skill scores, and the effect of model top elevation, topography, season, atmospheric background state and synoptic weather patterns on these scores are investigated. The results show a strong dependence of ICAR skill on the choice of the model top elevation, with the highest scores obtained for 4 km above topography. Furthermore, ICAR is found to provide added value over its ERA-Interim reanalysis forcing data set for alpine weather stations, improving the median of mean squared errors (MSEs) by 30 % and up to 53 %. It performs similarly during all seasons with a MSE minimum during winter, while flow linearity and atmospheric stability are found to increase skill scores. ICAR scores are highest during weather patterns associated with flow perpendicular to the Southern Alps and lowest for flow parallel to the alpine range. While measured precipitation is underestimated by ICAR, these results show the skill of ICAR in a real-world application, and may be improved upon by further observational calibration or bias correction techniques. Based on these findings ICAR shows the potential to generate downscaled fields for long-term impact studies in data-sparse regions with complex topography.

Abstract. We study a firn and ice core drilled at the new "Lock-In" site in East Antarctica, located 136 km away from Concordia station towards Durmont d'Urville. High resolution chemical and physical measurements were performed on the core, with a particular focus on the trapping zone of the firn where air bubbles are formed. We measured the air content in the ice, closed and open porous volumes in the firn, firn density, firn liquid conductivity and major ion concentrations, as well as methane concentrations in the ice. The closed and open porosity volumes of firn samples were obtained by the two independent methods of pycnometry and tomography, that yield similar results. The measured increase of the closed porosity with density is used to estimate the air content trapped in the ice with the aid of a simple gas trapping model. Results show a discrepancy, with the model trapping too much air. Experimental errors have been considered but do not explain the discrepancy between the model and the observations. The model and data can be reconciled with the introduction of a reduced compression of the closed porosity compared to the open porosity. Yet, it is not clear if this limited compression of closed pores is the actual mechanism responsible for the low amount of air in the ice. High resolution density measurements reveal the presence of a strong layering, manifesting itself as centimeter scale variations. Despite this heterogeneous stratification, all layers, including the ones that are especially dense or less dense compared to their surroundings, display similar pore morphology and closed porosity as function of density. This implies that all layers close in a similar way, even though some close in advance or later compared to the bulk firn. Investigation of the chemistry data suggests that in the trapping zone, the observed stratification is partly related to the presence of chemical impurities.
La idea de Europa de Hugo von Hofmannsthal (1914-1927) en el contexto de la Revolución Conservadora
Authors: Ramas San Miguel Clara
Published: June 2019

En este artículo se estudia la idea de Europa que el poeta austríaco Hugo von Hofmannsthal desarrolla desde los albores de la Primera Guerra Mundial hasta entrada la República de Weimar. Hofmannsthal reivindica una idea de Europa que a la vez contenga, realice y supere a los Estados-nación; y cuyo núcleo no sería Alemania -excesivamente inclinada hacia el modelo prusiano como bloque homogéneo y cerrado sobre sí mismo-, sino Austria-Hungría -como Imperio duradero, nexo con Oriente, frontera fluida y comunidad plural de pueblos diversos-. Con ello, Hofmannsthal se distancia de las tendencias dominantes en la Revolución Conservadora alemana. En primer lugar se presenta esta corriente, especialmente en la figura de Mœller van den Bruck; a continuación se exponen las reflexiones de Hofmannsthal sobre la guerra y sobre el modelo austríaco; finalmente se sintetiza su propuesta de una nueva idea de Europa.

Of Gods and Kings: Ashur Imagery in Nahum
Authors: Cook Gregory D.
Published: June 2019

Despite recognizing allusions to Ishtar in Nahum, commentators have not discussed the presence of Ashur imagery in the book. This article contends that Nah 3:18 identifies Yhwh’s ambiguous single male adversary as Assyria’s war god, Ashur. The phrase (3:18) is multivalent, referring to both the “king of Assyria” and “King Ashur.” When the verse is read in light of Assyrian inscriptions, it taunts Ashur that the human kings of Assyria no longer perform the duties assigned to them: shepherding and gathering the god’s people. The prophet, therefore, prophesied more than just Assyria’s demise; he also vilified the religion behind it.
