Du fœtus à la personne, l’invisible lien (Entretien avec Isabelle Baladier-Bloch)
Authors: Busnel Marie-Claire
Published: May 2020

Marie-Claire Busnel, qui fut chercheuse au Laboratoire de physiologie acoustique de l’inra, décrit au cours d’un entretien avec Isabelle Baladier-Bloch le parcours de ses recherches, ciblées d’abord sur la fonction des ultra-sons chez les chauves-souris, puis sur les effets du vacarme chez les enfants, et finalement sur les liens – invisibles – qui se tissent entre le fœtus et sa mère, le fœtus et son environnement sonore, domaine jusqu’ici resté dans l’ombre.
Short-term Perceptual Learning Game Does Not Improve Patching-Resistant Amblyopia in Older Children
Authors: Lee Yoon H. , Maniglia Marcello , Velez Federico , Demer Joseph L. , Seitz Aaron R. , Pineles Stacy
Published: May 2020

Purpose:

To investigate self-administered, at-home use of a perceptual learning–based video game consisting of target detection of stimuli in different sizes, spatial frequency, orientation, and contrast as a potential dichoptic therapy to improve binocular function in amblyopic patients resistant to patching.

Methods:

Children (ages 8 to 18 years) with strabismic and/or anisometropic amblyopia were recruited from a single institution. All participants (n = 25) were prescribed 6 weeks of patching for 2 hours per day, and those whose visual acuity did not improve were randomized to binocular perceptual learning (n = 7), monocular perceptual learning (n = 8), or patching (n = 10) groups for 8 weeks in this prospective cohort study. After an 8-week long period of treatment cessation, during which participants stopped patching or perceptual learning, participants in the patching group were randomized to binocular or monocular perceptual learning training; those in the perceptual learning groups remained the same. Visual function was assessed by visual acuity, low contrast acuity, reading speed, stereoacuity, and binocularity; compliance was evaluated by exercise logs.

Results:

There were no significant improvements in visual function parameters, which did not vary by treatment group. However, some visual outcomes, such as binocular summation and reading speed, correlated positively with compliance to perceptual learning therapy.

Conclusions:

At-home, self-administered use of this perceptual learning–based video game–based visual training does not consistently add therapeutic benefit to those with amblyopia resistant to patching. Future investigation is required to determine whether methods to increase compliance will lead to more reliable outcomes.

Religions de l’Inde : études shivaïtes
Authors: Bansat-Boudon Lyne
Published: May 2020

On note, dans le Gītārthasaṃgraha, commentaire d’Abhinavagupta à la Bhagavadgītā śivaïte, des observations qui relèvent de la pensée esthétique indienne. Or l’une des gloses aux Spandakārikā, « Les strophes du spanda », à savoir, la Vivṛti ou Spandavivṛti [SpV], œuvre de Rāmakaṇṭha, propose une exégèse tout à fait originale de la strophe 22. – Dans la lignée des raisonnements d’Abhinavagupta, elle montre combien la pensée esthétique pénètre les spéculations du śivaïsme non dualiste cachemirien et constitue ce que j’appellerai « une approche esthétique d’une phénoménologie de la transcendance ». Pour y avoir consacré plusieurs séminaires, c’est de cette glose que nous allons nous efforcer, ici, de rendre compte, d’autant qu’elle a le mérite d’illustrer l’intertextualité continûment à l’œuvre dans ce système de pensée.
Divinités de la structuration du territoire (suite) : Dionysos à Athènes
Authors: Chatzivasiliou Despina
Published: May 2020

À la suite de nos conférences de l’année dernière sur Déméter et Artémis, nous avons poursuivi notre enquête sur la structuration de l’espace urbain et péri-urbain de l’Attique à l’époque archaïque et classique, avec les cultes en l’honneur de Dionysos. Les études sur Dionysos sont abondantes mais incomplètes, et nous constatons une vraie lacune dans nos connaissances sur la localisation, l’implantation et l’évolution des lieux de son culte à Athènes. En revanche, les représentations du dieu des banquets sont fréquentes et éclairantes quant à sa popularité. Une présentation des sources et des vestiges sur Dionysos en Limnais, Lénaion, Dionysos Éleuthèreus et Ikarion offre une large possibilité d’interprétations cultuelles.
La locutio angelica dans la scolastique médiévale
Authors: Rosier-Catach Irène
Published: May 2020

La question du langage des anges est un des lieux privilégiés où les théologiens médiévaux se sont intéressés au langage. De ces analyses ressortent trois points, qui sont liés : d’une part la question est spéculative, au sens où elle n’a pas pour objet l’explication d’un passage scripturaire particulier, et concerne surtout sur le parler des anges entre eux ; d’autre part, les théologiens mènent leur réflexions en mettant systématiquement en parallèle la manière dont les anges parlent et la manière dont « nous » parlons ; enfin, comme c’est le cas pour d’autres questions concernant l’analyse du langage, telle celle des formules sacramentelles ou des noms et attributs divins notamment, les théologiens empruntent des notions aussi bien aux sources philosophiques (Aristote notamment) qu’aux sources théologiques (Augustin en premier lieu).

Arts visuels et christianisme (xixe-xxie siècle)
Authors: Saint-Martin Isabelle
Published: May 2020

Au cours des années académiques 2014-2015 et 2015-2016, un premier axe du séminaire s’est attaché au décor des églises de l’entre-deux guerres d’une part à travers les figures majeures de Maurice Denis et George Desvallières (objet d’une exposition au Petit Palais au printemps 2016), fondateurs en 1919 des Ateliers d’art sacré, d’autre part autour de la thématique de la Grande Guerre qui a suscité de nombreuses manifestations en 2014. Le motif de la Pietà qui ressurgit tant dans les vitraux commémoratifs que dans les monuments aux morts a servi de lien avec une exploration plus contemporaine des variations de la figure christique dans la photographie. Puis, la participation à l’exposition consacrée aux vitraux du xxe siècle par le Cité de l’architecture et du patrimoine, a conduit à poursuivre les réflexions ouvertes les années précédentes sur la place de l’abstraction et de la figuration dans les édifices religieux.
Mystique musulmane
Authors: Lory Pierre
Published: May 2020

Le Coran décrit en de multiples passages l’harmonie sans faille de l’univers : celle des corps célestes et de la météorologie, celle des mondes minéral et végétal. Le monde animal, fréquemment évoqué (cf. cours de l’année 2011-2012) est composé d’espèces intelligentes, obéissantes à leur Créateur. De façon symétrique, les anges concourent également à cette harmonie cosmique (cf. cours 2012-2013). Il n’est que le genre humain pour se montrer ingrat, rebelle, mécréant. Or les humains sont néanmoins considérés comme les lieutenants de Dieu sur la terre, le sommet et le but même de la création – comme si leur capacité de pécher recelait précisément un mystère du projet divin. C’est à explorer le paradoxe de l’impiété humaine que le cours de cette année a été consacré, en se fondant sur la littérature mystique des cinq premiers siècles de l’ère hégirienne, notamment les commentaires des versets coraniques sur les péchés d’Iblîs-Satan et d’Adam.

Published: May 2020

Le cycle de conférences sur les divinités de la structuration du territoire en Attique (notamment Déméter, Artémis et Dionysos), arrive sur sa troisième année avec l’étude d’Athéna et le rôle de la divinité poliade sur la structuration de l’espace urbain et péri-urbain de l’Attique aux époques archaïque et classique. Athéna, en tant que Polias, Nikè, Promachos, Erganè, Pallas, Phratria, Areia, Hygieia et Parthénos, est honorée sur la colline sacrée de l’Acropole, délimitée par l’enceinte du Pélasgikon, dont l’interprétation est multiple. Notre étude se porte en parallèle sur les cultes d’Athéna dans l’asty (surtout Palladion et Aréopage) et dans le territoire (Hérakleion de Marathon, Sounion et Pallène). La présence des différentes facettes d’Athéna est attestée non seulement par les sanctuaires en son honneur, mais aussi par les offrandes.

Recherches sur Poséidon : espaces narratifs et espaces cultuels à Athènes
Authors: de Polignac François
Published: May 2020

L’enquête sur Poséidon ne pouvait pas ne pas aborder la question du rôle du dieu à Athènes, en raison de la place centrale qu’il y tient à la fois dans les légendes des origines de la cité que dans le système cultuel athénien. Mais le faire trop tôt eût été risquer de s’enfermer dans des schémas trop connus ou des thématiques trop bien balisées, comme celle de l’autochtonie. C’est donc à dessein que la question avait été laissée de côté jusque-là. Inversement, l’éclairage apporté dans les années précédentes sur divers aspects des modes d’action et de présence du dieu a permis de revenir sur ce thème avec davantage de recul.

Design and Analysis of Three-Point Pressure for Varus Foot Deformity
Authors: Kadhim Fahad Mohanad , Al-Din Tahir Muhammad Safa
Published: May 2020

It is known that the deformities that affect the lower limbs are multiple in terms of location and severity of the injury. These deformities are treated with the use of orthosis, which varies depending on the type of deformity and the area of ​​injury. The principle on which the orthosis depends on the treatment of deformities is applying three-point pressures. These pressures are applied during the manufacturing process of the orthosis but with the time when the deformation response to treatment by corrected forces these mean the value and location of these corrective forces will change and this requires the manufacturing of a new orthosis. This requires costs in money and time to re-correct these forces. In this study, a force correction system was suggested that could change the value and location of corrective forces without need to manufacture a new orthosis and within a few minutes by placing an air chamber on the side of the orthosis. When increasing or withdrawing the amount of air inside the air chamber, the magnitudes of corrected force change according to the required value, this process providing comfort to the patient and reducing the effort of the professional staff supervisor (orthotist) to correct the deformity. The result showed that a method of correction forces applied by using the air chamber to correct deformities was successful when applied to a patient with varus foot deformity where the pressure generated from the air chamber on the leg was measured by using the F-Socket devise at the lateral side recorded a higher interface pressure (140Kpa) than the others sides due to pump the air to push the ankle joint for correction deformity without needing to manufacture of a new orthosis to change the values of correction forces thus reducing the cost and time to treat deformity, also the result showed improvement of the gait cycle, the value of ground reaction force on the body and footprint of the patient when comparing the results before and after the use of the orthosis by the patient.
Design of a Biomimetic SACH Foot: An Experimentally Verified Finite Element Approach
Authors: Balaramakrishnan Thirunindravur Mannan , Natarajan Sundararajan , Sujatha Srinivasan
Published: May 2020

The Solid Ankle Cushioned Heel (SACH) foot is a commonly prescribed prosthetic foot for the rehabilitation of lower limb amputees. From the viewpoint of its biomechanical performance, the foot is known to cause drop-off effect and asymmetry in amputee gait. Therefore, the objective of this work is to improvise the effective foot length ratio (EFLR) and the progression of the centre of pressure (CoP) of the SACH foot by providing a novel design approach that utilizes finite element analysis. Boundary conditions employed for evaluating the roll-over characteristics of prosthetic feet were numerically incorporated in this work. The non-linear mechanical behavior of the foot was included with the incorporation of large deformation, a hyperelastic material model and the Augmented Lagrangian contact formulation. Outcomes from the simulations were experimentally verified using an inverted pendulum-like apparatus, thereby substantiating the numerical approach. The design process of the SACH foot involved the modification of the elastic modulus of its components for enhancing the parameters of interest. Results obtained presented a 5.07% increase in the EFLR and a 9.29% increase in the anteroposterior progression of the CoP, which may improve amputee stability. The design solution presented may support the large user base of the SACH foot towards achieving enhanced gait characteristics during ambulation. Moreover, this work successfully demonstrates a novel design procedure for a prosthetic foot through an effective numerical implementation.
Diversity and nutritional value of pollen harvested by honey bee (Hymenoptera: Apidae) colonies during lowbush blueberry and cranberry (Ericaceae) pollination
Authors: Dufour Claude , Fournier Valérie , Giovenazzo Pierre
Published: May 2020

The growth of the commercial pollination industry raises important concerns regarding honey bee (Apis mellifera Linnaeus; Hymenoptera: Apidae) health and development. While providing such services, honey bees are often exposed to undiversified pollen sources that may contribute to nutritional deficiencies, notably in protein and amino acids. To understand how honey bees are affected during provision of pollination services, we compared honey bee colonies that pollinated lowbush blueberry (Vaccinium angustifolium Aiton; Ericaceae) and/or cranberry (Vaccinium macrocarpon Aiton; Ericaceae) crops (management strategies) with control colonies in a diversified farmland environment. We identified the floral species of pollen collected by honey bee colonies in those crops compared to pollen collected by control colonies. We also analysed the protein and essential amino acid content of collected pollen and bee bread and measured the nutritional impact of pollination services on honey bee colonies. We found that honey bees providing blueberry and/or cranberry pollination services are exposed to a less diversified pollen diet than colonies located in a farmland environment, especially in a cranberry field. There was a significantly lower proportion of crude protein content in collected and stored pollen during provision of blueberry pollination services, which led to a smaller brood population. Many nutritional deficiencies were measured with regards to essential amino acids.

A 45-year-old Caucasian myopic woman with a severe vision impairment (20/320) in the left eye due to a macula-off rhegmatogenous retinal detachment (RRD) underwent vitrectomy with silicone oil tamponade followed by an inferior relaxing retinectomy with heavy silicone oil tamponade during the second procedure for recurrence of RRD due to proliferative vitreoretinopathy. Four weeks after the second surgery, visual acuity was 20/200 and the patient complained metamorphopsia in the same eye due to a large full-thickness macular hole. A perfluorocarbon liquid-assisted inverted inner limiting membrane-flap technique was performed. Visual acuity improved to 20/80 after closing of macular hole and partial recovery of outer retinal layers at 3 months from the last surgery.

Over the past few years, the designing in smart agriculture system is a very important concept. Using
smart farming techniques we can build up the crop yield, and concurrently attain better output from the input.
In precision agriculture, a wireless sensor network brings a cost-effective solution to watch and manipulate.
We already have many wireless protocols like Wi-Fi, Cellular, BLE (Bluetooth low energy), etc. Although this
automation, not optimal for cultivation sensor nodes, there is a demand to send information to a great
distance without an internet connection. This leads to boost the LoRa (Long range) technology, which can do
very long-range transmission with the lowest cost [14]. The paper provides a brief survey of certain
requirements for Smart Agriculture such as wireless sensor networks.
Editorial - (Re) diseño desobediente: recrear mundos y abrir posibles
Authors: Callén Blanca , Martínez Morant Mara , Rispoli E. R.
Published: May 2020

Desde disciplinas como la filosofía (Foucault, 1990), los estudios sociales de la ciencia y la tecnología (Winner, 1980; Latour, 1998) o más recientemente la antropología del diseño (Smith et al, 2016), hace tiempo que se asume y pone de manifiesto cómo los dispositivos tecnológicos y los objetos de diseño “tienen” política. Si “la tecnología es sociedad hecha para que dure” (Latour, 1998), los objetos de diseño también son una expansión de esa durabilidad social hecha materia. Lejos de una supuesta neutralidad muda e inerte de los objetos en manos de una voluntad humana que los instrumentaliza y dirige hacia sus propios fines, las cualidades estéticas, formales y matéricas de objetos cotidianos e infraestructuras incorporan, de forma situada, disposiciones materiales que favorecen unos intereses por encima de otros, convocan o excluyen a diferentes colectivos, favorecen o dificultan ciertas acciones, composiciones y comportamientos, y a través de su uso hacen más o menos compatibles, plausibles u obligatorias ciertas formas de vida: lo social es una continuidad del diseño y viceversa.

A ese respecto, Langdon Winner señala: “Las cosas que llamamos ‘tecnologías’ son maneras de establecer orden en nuestro mundo. Muchos  sistemas y dispositivos técnicos importantes en nuestra vida cotidiana contienen posibilidades para  ordenar la actividad humana de muchas maneras diferentes. De forma más o menos consciente y  voluntaria, las sociedades eligen estructuras y tecnologías que influencian la manera en que la gente,  comunica, viaja, consume, va al trabajo, etc., durante un periodo muy largo de tiempo.   […]

Los asuntos que dividen —o unen— las personas en una sociedad no residen solamente en las  instituciones y en las prácticas de la política en el sentido tradicional de la palabra, sino también  —y de forma menos obvia— en infraestructuras tangibles de hierro y hormigón, cables y transistores,  tornillos y tuercas” (1980, p. 128).

Authors: Corring, PhD Deborah J. , Johnston, MA Megan E. , Rudnick, MD, PhD Abraham
Published: May 2020

Therapeutic horseback riding (THR) for inpatients with schizophrenia has not been examined, although it may benefit this particularly impaired population. This exploratory study aimed at studying THR for such individuals. Six inpatients with schizophrenia participated in 10 weekly sessions of THR. Validated transcriptions of semistructured interviews with these patients and with their accompanying staff as well as with the THR instructor over a few points in time were analyzed for themes. THR was found to be beneficial for this group of inpatients; in particular, they enjoyed themselves. In conclusion, THR has promise for this population, possibly as an enhancer of enjoyment, among other things, and should be further developed and studied for individuals with schizophrenia of varying severity.

Addressing osteoarthritis pain among older adult women through aquatic therapy: A new look at shallow-water movement
Authors: Saunders, PhD Mark V. , Piatt, PhD, CTRS Jennifer A. , Ramos, PhD William D. , Kennedy-Armbruster, PhD Carol , McCormick, PhD, CTRS Bryan P.
Published: May 2020

This study evaluated a shallow-water intervention to reduce pain among women age 61 to 81 with knee and/or hip osteoarthritis. The study used a randomized-replicated single-case two-condition crossover design to determine which condition was more effective at relieving pain. One condition was functional movements without the use of a stationary pole; the other condition, identical movements with the pole. Data were collected through repeated pain measures, pre-test-post-test measures, and retrospective pre-test post-test measures. Pain data analysis with Microsoft Excel® ExPRT 2.0 AB program generated pre- and post-crossover charts. Visual analysis findings were substantiated with sensitivity analyses of retrospective pre-test and post-test data, showing no significance between the two conditions (p ≤ 0.05). Results indicated use of a pole might not be more effective than the movement program itself. For the individual and recreation therapist, this finding might translate to cost effective recreation therapy interventions addressing clinical outcomes as a result from engagement with an aquatic RT movement program.

Published: May 2020

Camps may be beneficial environments to provide military families with opportunities to participate in meaningful leisure to revitalize family relationships and to form connections within the military family community. While research has investigated the effects of these programs on veterans and families, limited research incorporates consumer-based evaluations of the service provider. Thus, the purpose of this study was to perform an evaluation of a therapeutic, recreation-based military family camp. A multiphase importance performance analysis (IPA) was implemented with 19 individuals who attended the camp. Participants rated program components using a 5-point Likert scale. Results revealed high importance and performance scores on all program components, as well as highlighted areas of programing with opportunity for maintenance and improvement.

Objective: As part of the evaluation of the Whole Health Primary Care Pain Education and Opioid Monitoring Program (PC-POP), we compared demographic and health characteristics between participants and nonparticipants drawn from the same defined population.Design/Methods: Retrospective chart review comparing participants and nonparticipants in terms of two categories of variables: (1) demographic characteristics and (2) physical/mental health characteristics.Setting: VA Primary Care.Subjects: Adult veterans with chronic noncancer pain receiving opioid therapy >3 months being managed in primary care.Results: A total of 749 veterans (424 participants in PC-POP and 325 nonparticipants) were included in the final analysis. Results showed that nonparticipation was associated with more widespread musculoskeletal pain, low back pain, anxiety, higher mortality, and rural areas. Participation was associated with more medical diagnoses overall, hypertension, sleep apnea, fibromyalgia, peripheral nerve pain, depression, and female gender. Other demographic and physical/mental health variables did not significantly differ between the groups.Conclusions: Given that primary care is the dominant healthcare setting in which opioids are prescribed for chronic noncancer pain, programs are needed to assist primary care providers to meet the rigorous requirements of guideline concordant care. The current study examined participation factors in such a program and found that certain veterans were less likely to participate than others. Identifying such veterans at the outset, in combination with intentional recruitment efforts and individualized interventions, may promote entry into PC-POP.

Published: May 2020

Objective: Two patient case reports are presented describing the use of cannabidiol (CBD) for the symptomatic relief of a lumbar compression fracture and in the mitigation of thoracic discomfort and dysesthesia secondary to a surgically resected meningioma.Discussion: CBD appears to have antisnociceptive and anti-inflammatory effects on opioid-naive patients with neuropathic and radicular pain. Of note, the patients in this case series used the same CBD cream: Baskin Essentials Body Wellness Cream (400 mg CBD per two oz.)Conclusion: Hemp-derived CBD in a transdermal cream provided significant symptom and pain relief for the patients described in this case series. Based on these results, we believe further investigation is warranted to see if CBD-containing products should have a more prominent role in the treatment of acute and chronic pain.
Deposition of brown carbon onto snow: changes in snow optical and radiative properties
Authors: Beres Nicholas D. , Sengupta Deep , Samburova Vera , Khlystov Andrey Y. , Moosmüller Hans
Published: May 2020

Abstract. Light-absorbing organic carbon aerosol – colloquially
known as brown carbon (BrC) – is emitted from combustion processes and has
a brownish or yellowish visual appearance, caused by enhanced light
absorption at shorter visible and ultraviolet wavelengths (0.3 µm≲λ≲0.5 µm). Recently, optical
properties of atmospheric BrC aerosols have become the topic of intense
research, but little is known about how BrC deposition onto snow surfaces
affects the spectral snow albedo, which can alter the resulting radiative
forcing and in-snow photochemistry. Wildland fires in close proximity to the
cryosphere, such as peatland fires that emit large quantities of BrC, are
becoming more common at high latitudes, potentially affecting nearby snow
and ice surfaces. In this study, we describe the artificial deposition of BrC aerosol with
known optical, chemical, and physical properties onto the snow surface, and
we monitor its spectral radiative impact and compare it directly to modeled
values. First, using small-scale combustion of Alaskan peat, BrC aerosols
were artificially deposited onto the snow surface. UV–Vis absorbance and
total organic carbon (TOC) concentration of snow samples were measured for
samples with and without artificial BrC deposition. These measurements were
used to first derive a BrC (mass) specific absorption (m2 g−1)
across the UV–Vis spectral range. We then estimate the imaginary part of the
refractive index of deposited BrC aerosol using a volume mixing rule. Single-particle optical properties were calculated using Mie theory, and these
values were used to show that the measured spectral snow albedo of snow with
deposited BrC was in general agreement with modeled spectral snow albedo
using calculated BrC optical properties. The instantaneous radiative forcing
per unit mass of total organic carbon deposited to the ambient snowpack was
found to be 1.23 (+0.14/-0.11) W m−2 per part per million (ppm). We estimate the same
deposition onto a pure snowpack without light-absorbing impurities would
have resulted in an instantaneous radiative forcing per unit mass of 2.68
(+0.27/-0.22) W m−2 per ppm of BrC deposited.

Abstract. Photochemistry plays an important role in the evolution of atmospheric water-soluble organic carbon (WSOC), which dissolves into clouds, fogs, and aerosol
liquid water. In this study, we tentatively examined the molecular
composition and evolution of a WSOC mixture extracted from field-collected
wheat straw burning aerosol (WSBA) samples upon photolysis, using direct
infusion electrospray ionisation (ESI) coupled to high-resolution mass
spectrometry (HRMS) and liquid chromatography (LC) coupled with HRMS. For
comparison, two typical phenolic compounds (i.e. phenol and guaiacol)
emitted from lignin pyrolysis in combination with hydrogen peroxide
(H2O2) as a typical OH radical precursor were simultaneously
exposed to simulated sunlight irradiation. Their photochemical products such
as phenolic dimers (e.g. m∕z 185.0608 for phenol dimer and m∕z 245.0823 for
guaiacol dimer) or their isomers, were also observed in field-collected WSBA
samples, suggesting that the aqueous-phase reactions might contribute to the
formation of emitted biomass burning aerosols. The aqueous photochemistry of
both the phenols (photooxidation) and WSBA extracts (direct photolysis)
could produce a series of highly oxygenated compounds, which in turn
increases the oxidation degree of organic composition and acidity of the
bulk solution. In particular, the LC/ESI-HRMS technique revealed significant
photochemical evolution of the WSOC composition in WSBA samples, e.g. the
photodegradation of low oxygenated species and the formation of highly
oxygenated products. We also tentatively compared the mass spectra of
photolytic time-profile WSBA extracts with each other for a more
comprehensive description of the photolytic evolution. The calculated
average oxygen-to-carbon ratio (O∕C) of oxygenated compounds in bulk extract
increases from 0.38±0.02 to 0.44±0.02 (mean ± standard
deviation), while the intensity (S∕N)-weighted average O∕C (O∕Cw)
increases from 0.45±0.03 to 0.53±0.06 as the time of
irradiation extends from 0 to 12 h. These findings indicate that the water-soluble organic fraction of combustion-derived aerosols has the potential to
form more oxidised organic matter, contributing to the highly oxygenated
nature of atmospheric organic aerosols.

Abstract. ClNO2 and Cl2 can affect atmospheric oxidation and thereby the
formation of ozone and secondary aerosols, yet their sources and production
mechanisms are not well understood or quantified. In this study we present
field observations of ClNO2 and Cl2 at a suburban site in eastern
China during April 2018. Persistent high levels of ClNO2 (maximum:
∼3.7 ppbv; 1 min average) were frequently observed at night,
due to the high ClNO2 yield (φ (ClNO2), 0.56±0.20)
inferred from the measurements. The φ (ClNO2) value showed a
positive correlation with the [Cl−] / [H2O] ratio, and its
parameterization was improved at low to median yields (0–0.75) by the incorporation of [Cl−] / [H2O] and the suppression
effect of aerosol organics. ClNO2 and Cl2 showed a significant
correlation on most nights. We show that the Cl2 at our site was more
likely a co-product with ClNO2 from N2O5 uptake on acidic
aerosols that contain chloride than being produced by ClNO2 uptake as
previously suggested. We propose a mechanism in which NO2+ can
react with Cl− to produce Cl2 and ClNO2 simultaneously. Under
a new framework which regards Cl2, ClNO2, and nitrate as products
of N2O5 uptake, the Cl2 yield (φ (Cl2)) was
derived using ambient data. φ (Cl2) exhibited significant
correlations with [Cl−] and [H+], based on which a
parameterization of φ (Cl2) was developed. The derived
parameterizations of φ (ClNO2) and φ (Cl2)
can be used in models to evaluate the nighttime production of ClNO2 and
Cl2 and their impact on the next day's photochemistry.
Developing a novel hybrid model for the estimation of surface 8 h ozone (O3) across the remote Tibetan Plateau during 2005–2018

Abstract. We developed a two-stage model called the random-forest–generalised additive
model (RF–GAM), based on satellite data, meteorological factors, and other
geographical covariates, to predict the surface 8 h O3 concentrations
across the remote Tibetan Plateau. The 10-fold cross-validation result
suggested that RF–GAM showed excellent performance, with the highest
R2 value (0.76) and lowest root-mean-square error (RMSE)
(14.41 µg m−3), compared with other seven machine-learning models. The
predictive performance of RF–GAM showed significant seasonal
discrepancy, with the highest R2 value observed in summer (0.74),
followed by winter (0.69) and autumn (0.67), and the lowest one in spring
(0.64). Additionally, the unlearning ground-observed O3 data collected
from open-access websites were applied to test the transferring ability of the
novel model and confirmed that the model was robust in predicting the surface
8 h O3 concentration during other periods (R2=0.67, RMSE = 25.68 µg m−3). RF–GAM was then used to predict the daily 8 h
O3 level over the Tibetan Plateau during 2005–2018 for the first time. It
was found that the estimated O3 concentration displayed a slow increase,
from 64.74±8.30 µg m−3 to 66.45±8.67 µg m−3 from 2005 to 2015, whereas it decreased from the peak to 65.87±8.52 µg m−3 during 2015–2018. Besides this, the estimated 8 h
O3 concentrations exhibited notable spatial variation, with the highest
values in some cities of the northern Tibetan Plateau, such as Huangnan (73.48±4.53 µg m−3) and Hainan (72.24±5.34 µg m−3), followed by the cities in the central region, including Lhasa
(65.99±7.24 µg m−3) and Shigatse (65.15±6.14 µg m−3), and the lowest O3 concentration occurred in a city of
the southeastern Tibetan Plateau called Aba (55.17±12.77 µg m−3).
Based on the 8 h O3 critical value (100 µg m−3) provided by
the World Health Organization (WHO), we further estimated the annual mean
nonattainment days over the Tibetan Plateau. It should be noted that most of the
cities on the Tibetan Plateau had excellent air quality, while several
cities (e.g. Huangnan, Haidong, and Guoluo) still suffered from more than
40 nonattainment days each year, which should be given more attention in order to
alleviate local O3 pollution. The results shown herein confirm that the
novel hybrid model improves the prediction accuracy and can be applied to
assess the potential health risk, particularly in remote regions with
few monitoring sites.
Technical note: Estimating aqueous solubilities and activity coefficients of mono- and α, ω-dicarboxylic acids using COSMO-RS-DARE

Published: May 2020

Abstract. We have used the COSMOtherm program to estimate activity coefficients and solubilities of mono- and α, ω-dicarboxylic acids, and water in binary acid-water systems. The deviation from ideality was found to be larger in the systems containing larger acids than in the systems containing smaller acids. We found a better agreement between estimated and experimental activity coefficients of monocarboxylic acids when the water clustering with a carboxylic acid and itself was taken into account using the dimerization, aggregation and reaction extension (COSMO-RS-DARE) of COSMOtherm. Based on effective equilibrium constants of different clustering reactions in the binary solutions, acid dimer formation is more dominant in systems containing larger dicarboxylic acids (C5–C8), while for monocarboxylic acids (C1–C6) and smaller dicarboxylic acids (C2–C4), hydrate formation is more favorable, especially in dilute solutions.
Spectral correction of turbulent energy damping on wind LiDAR measurements due to range-gate averaging
Authors: Puccioni Matteo , Iungo Giacomo Valerio
Published: May 2020

Abstract. Continuous advancements in LiDAR technology have enabled compelling wind turbulence measurements within the atmospheric boundary layer with range gates shorter than 20 m and sampling frequency of the order of 10 Hz. However, estimates of the radial velocity from the back-scattered laser beam are inevitably affected by an averaging process within each range gate, generally modeled as a convolution between the actual velocity projected along the LiDAR line-of-sight and a weighting function representing the energy distribution of the laser pulse along the range gate. As a result, the spectral energy of the turbulent velocity fluctuations is damped within the inertial sub-range with respective reduction of the velocity variance, and, thus, not allowing to take advantage of the achieved spatio-temporal resolution of the LiDAR technology. In this article, we propose to correct this turbulent energy damping on the LiDAR measurements by reversing the effect of a low-pass filter, which can be estimated directly from the LiDAR measurements. LiDAR data acquired from three different field campaigns are analyzed to describe the proposed technique, investigate the variability of the filter parameters and, for one dataset, assess the procedure for spectral LiDAR correction against sonic anemometer data. It is found that the order of the low-pass filter used for modeling the energy damping on the LiDAR velocity measurements has negligible effects on the correction of the second-order statistics of the wind velocity. In contrast, its cutoff frequency plays a significant role in the spectral correction encompassing the smoothing effects connected with the LiDAR gate length.
