Abstract. Gaseous hydrochloric (HCl) and hydrobromic acid (HBr) are vital halogen
species that play essential roles in tropospheric physicochemical processes.
Yet, the majority of the current studies on these halogen species were
conducted in marine or coastal areas. Detection and source identification of
HCl and HBr in inland urban areas remain scarce, thus limiting the full
understanding of halogen chemistry and potential atmospheric impacts in the
environments with limited influence from the marine sources. Here, both
gaseous HCl and HBr were concurrently measured in urban Beijing, China,
during winter and early spring of 2019. We observed significant HCl and HBr
concentrations ranging from a minimum value at 1 × 108 molecules cm−3 (4 ppt) and 4 × 107 molecules cm−3 (1 ppt) up
to 6 × 109 molecules cm−3 (222 ppt) and 1 × 109 molecules cm−3 (37 ppt), respectively. The HCl and HBr
concentrations are enhanced along with the increase of atmospheric
temperature, UVB and levels of gaseous HNO3. Based on the air mass
analysis and high correlations of HCl and HBr with the burning indicators
(HCN and HCNO), gaseous HCl and HBr are found to be related to
anthropogenic burning aerosols. The gas–particle partitioning may also play
a dominant role in the elevated daytime HCl and HBr. During the daytime, the
reactions of HCl and HBr with OH radicals lead to significant production of
atomic Cl and Br, up to 2 × 104 molecules cm−3 s−1 and 8 × 104 molecules cm−3 s−1,
respectively. The production rate of atomic Br (via HBr + OH) is 2–3 times
higher than that of atomic Cl (via HCl + OH), highlighting the potential
importance of bromine chemistry in the urban area. On polluted days, the
production rates of atomic Cl and Br are faster than those on clean days.
Furthermore, our observations of elevated HCl and HBr may suggest an
important recycling pathway of halogen species in inland megacities and may
provide a plausible explanation for the widespread halogen chemistry,
which could affect the atmospheric oxidation in China.
Characterization of dark current signal measurements of the ACCDs used on board the Aeolus satellite

Published: July 2021

Abstract. Even just shortly after the successful launch of the
European Space Agency satellite Aeolus in August 2018, it turned out that
dark current signal anomalies of single pixels (so-called “hot pixels”) on
the accumulation charge-coupled devices (ACCDs) of the Aeolus detectors
detrimentally impact the quality of the aerosol and wind products,
potentially leading to wind errors of up to several meters per second. This paper provides
a detailed characterization of the hot pixels that occurred during the
first 1.5 years in orbit. The hot pixels are classified according
to their characteristics to discuss their impact on wind measurements.
Furthermore, mitigation approaches for the wind retrieval are presented and
potential root causes for hot pixel occurrence are discussed. The
analysis of the dark current signal anomalies reveals a large variety of
anomalies ranging from pixels with random telegraph signal (RTS)-like
characteristics to pixels with sporadic shifts in the median dark current
signal. Moreover, the results indicate that the number of hot pixels
almost linearly increased during the observing period between 2 September 2018
and 20 May 2020 with 6 % of the ACCD pixels affected in total at the end
of the period leading to 9.5 % at the end of the mission lifetime. This work
introduces dedicated instrument calibration modes and ground processors,
which allowed for a correction shortly after a hot pixel occurrence. The
achieved performance with this approach avoids risky adjustments to the
in-flight hardware operation. It is demonstrated that the success of the
correction scheme varies depending on the characteristics of each hot pixel
itself. With the herein presented categorization, it is shown that
multi-level RTS pixels with high fluctuation are the biggest challenge for
the hot pixel correction scheme. Despite a detailed analysis in this
framework, no conclusion could be drawn about the root cause of the hot
pixel issue.
Introducing GloRiSe – a global database on river sediment composition
Authors: Müller Gerrit , Middelburg Jack J. , Sluijs Appy 
Published: July 2021

Abstract. Rivers transport dissolved and solid loads from
terrestrial realms to the oceans and between inland reservoirs, representing
major mass fluxes on Earth's surface. The composition of river water and
sediment provides clues to a plethora of Earth and environmental processes,
including weathering, erosion, nutrient and carbon cycling, environmental
pollution, reservoir exchange, and tectonic cycles. While there are
documented, publicly available databases for riverine dissolved and
suspended nutrients, there is no openly accessible, georeferenced database
for riverine suspended sediment composition. Here, we present a globally
representative set of 2828 suspended and bed sediment compositional
measurements from 1683 locations around the globe. This database, named
Global River Sediments (GloRiSe) version 1.1, includes major, minor and trace
elements, along with mineralogical data, and provides time series for some
sites. Each observation is complemented by metadata describing geographic
location, sampling date and time, sample treatment, and measurement details,
which allows for grouping and selection of observations, as well as for
interoperability with external data sources, and improves interpretability.
Information on references, unit conversion and references makes the database
comprehensible. Notably, the close to globe-spanning extent of this
compilation allows the derivation of data-driven, spatially resolved global-scale
conclusions about the role of rivers and processes related to them within
the Earth system. GloRiSe version 1.1 can be downloaded from Zenodo
(https://doi.org/10.5281/zenodo.4485795, Müller et al.,
2021) and GitHub (https://github.com/GerritMuller/GloRiSe, last access: 26 May 2021),
where updates with adapted version numbers will become available, along
with a technical documentation and an example calculation in the form of
MATLAB scripts, which calculate the sediment-flux-weighted major element
composition of the annual riverine suspended sediment export to the ocean
and related uncertainties.

Published: July 2021

Abstract. We present a new publicly available daily gridded dataset
of maximum and minimum temperature and precipitation data covering the whole
territory of Slovenia from 1950 to 2018. It represents the great variability
of climate at the crossroads between the Mediterranean, Alpine and
continental climatic regimes with altitudes between 0–2864 m a.s.l. We
completely reconstructed (quality control and gap filling) the data for the
three variables from 174 observatories (climatological, precipitation and
automatic stations) with the original records all over the country. A
comprehensive quality control process based on the spatial coherence of the
data was applied to the original dataset, and the missing values were
estimated for each day and location independently. Using the filled data
series, a grid of 1×1 km spatial resolution with 20 998 points was created
by estimating daily temperatures (minimum and maximum) and precipitation,
as well as their corresponding uncertainties at each grid point. In order to show
the potential applications, four daily temperature indices and two on
precipitation were calculated to describe the spatial distribution of (1) the absolute maximum and minimum temperature, (2) the number of frost days,
(3) the number of summer days, (4) the intensity of precipitation and (5) the
maximum number of consecutive dry days. The use of all the available
information, the complete quality control and the high spatial resolution of the grid allowed for an accurate estimate of precipitation and temperature that represents a precise spatial and temporal distribution of daily
temperatures and precipitation in Slovenia. The SLOCLIM dataset is publicly
available at https://doi.org/10.5281/zenodo.4108543 and

SCOPE 2.0: a model to simulate vegetated land surface fluxes and satellite signals
Authors: Yang Peiqi , Prikaziuk Egor , Verhoef Wout , van der Tol Christiaan 
Published: July 2021

Abstract. The Soil Canopy Observation of Photosynthesis and Energy fluxes (SCOPE) model aims at linking satellite observations in the visible, infrared, and thermal domains with land surface processes in a physically based manner, and quantifying the microclimate in vegetation canopies. It simulates radiative transfer in the soil, leaves, and vegetation canopies, as well as photosynthesis and non-radiative heat dissipation through convection and mechanical turbulence. Since the first publication 12 years ago, SCOPE has been applied in remote sensing studies of solar-induced chlorophyll fluorescence (SIF), energy balance fluxes, gross primary production (GPP), and directional thermal signals. Here, we present a thoroughly revised version, SCOPE 2.0, which features a number of new elements: (1) it enables the definition of layers consisting of leaves with different properties, thus enabling the simulation of vegetation with an understorey or with a vertical gradient in leaf chlorophyll concentration; (2) it enables the simulation of soil reflectance; (3) it includes the simulation of leaf and canopy reflectance changes induced by the xanthophyll cycle; and (4) the computation speed has been reduced by 90 % compared to earlier versions due to a fundamental optimization of the model. These new features improve the capability of the model to represent complex canopies and to explore the response of remote sensing signals to vegetation physiology. The improvements in computational efficiency make it possible to use SCOPE 2.0 routinely for the simulation of satellite data and land surface fluxes. It also strengthens the operability for the numerical retrieval of land surface products from satellite or airborne data.
Maximal power per device area of a ducted turbine
Authors: Bagheri-Sadeghi Nojan , Helenbrook Brian T. , Visser Kenneth D. 
Published: July 2021

Abstract. The aerodynamic design of a ducted wind turbine for maximum total power coefficient was studied numerically using the axisymmetric Reynolds-averaged Navier–Stokes equations and an actuator disc model. The total power coefficient characterizes the rotor power per total device area rather than the rotor area. This is a useful metric to compare the performance of a ducted wind turbine with an open rotor and can be an important design objective in certain applications. The design variables included the duct length, the rotor thrust coefficient, the angle of attack of the duct cross section, the rotor gap, and the axial location of the rotor. The results indicated that there exists an upper limit for the total power coefficient of ducted wind turbines. Using an Eppler E423 airfoil as the duct cross section, an optimal total power coefficient of 0.70 was achieved at a duct length of about 15 % of the rotor diameter. The optimal thrust coefficient was approximately 0.9, independent of the duct length and in agreement with the axial momentum analysis. Similarly independent of duct length, the optimal normal rotor gap was found to be approximately the duct boundary layer thickness at the rotor. The optimal axial position of the rotor was near the rear of the duct but moved upstream with increasing duct length, while the optimal angle of attack of the duct cross section decreased.
Grading in a Dilemmatic Space : An Exploratory Cross-cultural Analysis of Mathematics and Language Secondary Teachers
Authors: Pasquini Raphaël , Deluca Chris 
Published: July 2021

Numerous studies have shown that grading is a complex process that involves negotiating technical, social, and ethical factors. While previous research has primarily focused on the reliability, composition, and validity of teachers’ grades, few studies have examined grading practices across cultural contexts and teaching subjects. The purpose of this exploratory study was to analyze how culture and teaching subject influence teachers’ grading dilemmas. Based on individual and group interviews with 11 Canadian and eight Swiss teachers, and using a “dilemmatic space” conceptual framework, this article inductively identified five dilemmatic spaces across cultural contexts and teaching subjects. The paper concludes with a discussion of the cross-cutting dimensions across these five dilemmatic spaces and articulates implications for future research and practice.
Writing therapy: paradox, peril and promise
Authors: Murphy Ffion 
Published: July 2021

Belief in the remedial potential of the writing process has intensified in the past three decades, with scientific studies indicating health and wellbeing benefits; poets, novelists and memoirists proclaiming therapeutic effects; and, innovative and broad-ranging use of creative writing in counselling and health care. This paper proposes that tertiary writing education can benefit from the explicit study of writing therapy as a complex, evolving and contested set of theories and practices. It outlines and contextualises my own approach, discusses some relevant literature, and proposes future interdisciplinary mixed-methods research, for the time is ripe in Australia for writing and health teachers and researchers to work together to investigate writing’s risks, paradoxes and recuperative possibilities.
Plot interrupted: reproducing the narrative benefits of trauma fiction in crime fiction
Authors: Dodd Leanne 
Published: July 2021

Trauma distorts time and interrupts the natural flow of people’s life-stories. While bibliotherapists may prescribe fictional stories to help clients internalise better coping mechanisms and re-author their life stories, they rarely select crime fiction for this purpose. This article demonstrates how crime writers can create works that may fit the criteria for transformative therapy. Whitehead suggests that trauma fiction writers have ’frequently found that the impact of trauma can only adequately be represented by mimicking its forms and symptoms’ (2004: 3). By aligning the narrative strategies used in trauma fiction to distort time, such as fragmentation and repetition, with those strategies used in crime fiction, writers can develop a creative work that moves beyond the prevailing conventions of crime fiction to incorporate the well-being benefits of trauma fiction. The effect may transform perceptions and assist with reconnection, while also providing a safe narrative space for all readers to work through fears brought on by modern-day graphic exposure to traumatic events. This research may prove significant in developing a framework to cultivate a form of crime fiction that can direct readers into safe, controlled and custom-written environments where they may better empathise, explore and experiment with their responses to trauma.
Narratives of death and dying from one remove: surveying the undertaker’s memoir
Authors: Brien Donna Lee 
Published: July 2021

While most book-length published memoirs on the topic of death and dying could be broadly classified as illness memoirs, there are a surprising number of memoirs currently in circulation whose narratives focus on the life and work of the undertaker. Despite achieving a measure of popularity with readers, none of these works have been explored (individually or as a group) in detail or categorised as a discrete sub-set of the auto/biographical memoir. Surveying these narratives as a sub-genre of memoir – and examining their modes of writing, publication and public reception – can contribute to our understanding of both this revealing auto/biographical practice and practices of writing and publishing popular memoir more generally. A way of categorising these works is suggested, with representative memoirs in each category used as illustrative examples. In suggesting that these texts are able to communicate to readers on the often difficult topic of death and dying, this analysis serves to point to the power of auto/biographical writing.
Lived experience and personal narrative: pathways to connection
Authors: Byrne Louise 
Published: July 2021

First person narratives drawing on experiences in mental health settings and services provide important insights into the lived experience of suffering, healing and recovery. An emerging and influential role within mental health services is that of the ’lived experience’ worker. People employed in what are known as ‘lived experience’ roles have powerful stories to share. The use of personal narrative aids connection with current service users, demonstrating that hope for a better life is possible and challenging stereotypical or stigmatizing attitudes by highlighting shared humanity and common human experiences. This article tells one such story, where parallel narratives and multiple perspectives are used to highlight the benefit of encouraging vulnerability to foster connection.
Using blogging to engage nursing students in reflective practice
Authors: Ryan Colleen , Heidke Penny , Blunt Nicole , Williamson Moira , Brien Donna Lee 
Published: July 2021

Blogging is a practice that educators in creative and professional writing, journalism, communication and a variety of other writing-based programs utilise to enhance their students’ reflective writing, alongside other skills. This article suggests that this practice may be useful in other non-writing based disciplines, in this case the discipline of nursing, where reflective practice has been identified as a framework to assist in developing personal growth, problem solving and the identification of innate strengths, allowing professional maturation in difficult environments. It describes the use of blogging in an assessment item in a final year undergraduate nursing unit. Analysis of students’ blogs revealed blogging was cathartic and triggered reflection and transformation.

Engineering Solutions to the Problem of Hypersalinity in Florida Power & Light’s Turkey Point Cooling Canals
Authors: Echevarria Victor 
Published: July 2021

The aim of this project is to investigate engineering methods to reduce salinity in the cooling canals at the Florida Power & Light (FP&L) Turkey Point Power Plant. In order to stop discharging hot water from the plant into the adjacent Biscayne Bay, a cooling canal system was made operational in 1972 that occupies an area 3.2 km wide by 8.0 km long extending south of the plant. The 5,900 acre canal system has been measured at twice the salinity of the adjacent Biscayne Bay at as high as 68 ppt [Appendix i]. Florida Power & Light added a canal along the western perimeter of the cooling canal system to intercept seepage. The interceptor ditch enables FP&L to pump seepage back into the canal system during the dry season thus reducing the groundwater flow of hypersaline water to the west.
The Florida Department of Environmental Protection (FDEP) and the South Florida Water Management District (SFWMD) are monitoring a saltwater plume migrating west of FP&L property (FDEP/SFWMD Miami-Dade Saltwater Intrusion Presentation pg 3). Tidal influences have a profound effect on saltwater intrusion, so it is difficult to quantify the influence of the canals on this plume. To ensure that FP&L has no culpability in the contamination of ground water, the cooling canals should either operate at a lower level of salinity or be isolated to restrict flow to underground sources of water.
Isolation, however, is not an appealing option as the methods which have been conceptualized are highly invasive. Environmental concerns are abundant as the ecosystem within the cooling canals supports at least 17 protected species of birds and animals of South Florida. Over 25% of the world’s population of the American crocodile resides in the Turkey Point cooling canals. Very few organisms require a hypersaline condition to thrive; therefore, lowering the salt concentration of the canal system is not expected to have adverse effects upon the ecosystem. Careful attention must be paid to ensure wildlife survival during treatment and/or disposal system development and operation.
Le système de santé sous l’empire du management
Authors: Moyse Danielle 
Published: July 2021

Le 12 mars 2020, le Président de la République française, annonçant, à la télévision, la nécessité du confinement face à la pandémie de COVID-19, affirmait que la « priorité absolue » était la protection des personnes vulnérables. Cette priorité devait malheureusement se mettre en oeuvre dans un contexte de pénurie des personnels soignants et du matériel de protection, engendré par des politiques néolibérales de restrictions des dépenses publiques. Très rapidement, les personnels soignants se sont donc vus dans l’obligation de sélectionner les malades dans l’accès aux soins intensifs. Malgré la réaffirmation, par le Comité Consultatif National d’Éthique, de la dignité absolue de la personne humaine, et de l’impossibilité de distinguer les patients en fonction de leur utilité sociale, les soignants ont, sur recommandation des Agences Régionales de Santé, pourtant dû établir des critères d’admission en réanimation. Les témoignages de personnels soignants et textes officiels montrent que, en cas de crise, la prise en charge de tous, sans distinction d’âge, ou d’état de santé antérieur, n’est guère compatible avec la conception managériale du système de soin.
