Forest–atmosphere exchange of reactive nitrogen in a remote region – Part I: Measuring temporal dynamics
Authors: Wintjen Pascal , Schrader Frederik , Schaap Martijn , Beudert Burkhard , Brümmer Christian 
Published: January 2022

Abstract. Long-term dry deposition flux measurements of reactive nitrogen based on the
eddy covariance or the aerodynamic gradient method are scarce. Due to the
large diversity of reactive nitrogen compounds and high technical requirements
for the measuring devices, simultaneous measurements of individual reactive
nitrogen compounds are not affordable. Hence, we examined the exchange
patterns of total reactive nitrogen (ΣNr) and
determined annual dry deposition budgets based on measured data at a mixed
forest exposed to low air pollution levels located in the Bavarian Forest
National Park (NPBW), Germany. Flux measurements of
ΣNr were carried out with the Total Reactive
Atmospheric Nitrogen Converter (TRANC) coupled to a chemiluminescence
detector (CLD) for 2.5 years. The average ΣNr concentration was 3.1 µg N m−3. Denuder measurements with DELTA samplers and chemiluminescence
measurements of nitrogen oxides (NOx) have shown that NOx has the
highest contribution to ΣNr (∼51.4 %), followed by ammonia (NH3) (∼20.0 %),
ammonium (NH4+) (∼15.3 %), nitrate NO3- (∼7.0 %), and nitric acid (HNO3) (∼6.3 %). Only
slight seasonal changes were found in the ΣNr
concentration level, whereas a seasonal pattern was observed for the
contribution of NH3 and NOx. NH3 showed highest
contributions to ΣNr in spring and summer,
NOx in autumn and winter. We observed deposition fluxes at the measurement site with median fluxes
ranging from −15 to −5 ngNm-2s-1 (negative fluxes
indicate deposition). Median deposition velocities ranged from 0.2 to
0.5 cm s−1. In general, highest deposition velocities were
recorded during high solar radiation, in particular from May to September. Our
results suggest that seasonal changes in composition of
ΣNr, global radiation (Rg), and
other drivers correlated with Rg were most likely influencing
the deposition velocity (vd). We found that from May to
September higher temperatures, lower relative humidity, and dry leaf surfaces
increase vd of ΣNr. At the
measurement site, ΣNr concentration did not
emerge as a driver for the ΣNrvd. No significant influence of temperature, humidity, friction velocity, or wind
speed on ΣNr fluxes when using the
mean-diurnal-variation (MDV) approach for filling gaps of up to 5 days was
found. Remaining gaps were replaced by a monthly average of the specific
half-hourly value. From June 2016 to May 2017 and June 2017 to May 2018, we
estimated dry deposition sums of 3.8 and 4.0 kgNha-1a-1,
respectively. Adding results from the wet deposition measurements, we
determined 12.2 and 10.9 kgNha-1a-1 as total nitrogen
deposition in the 2 years of observation. This work encompasses (one of) the first long-term flux measurements of
ΣNr using novel measurements techniques for
estimating annual nitrogen dry deposition to a remote forest ecosystem.
A sanity check for earthquake recurrence models used in PSHA of slowly deforming regions: the case of SW Iberia

Published: January 2022

Abstract. Probabilistic seismic hazard assessment (PSHA), despite its deep criticism, is still the most common tool used to decide on the acceptable seismic
risk and corresponding mitigation measures. We propose two consistency tests to address the variability of earthquake generation models found in
PSHA studies: (i) one rule-of-thumb test where the seismic moment release from the model is converted to an average slip on a typical fault and
compared with known plate kinematics or GNSS deformation field and (ii) a test where using a neotectonic model the computed deformation is converted into seismic moment release and to a synthetic earthquake catalogue. We apply these tests to W and SW Iberia slowly deforming region, where two earthquake source areas are investigated: (1) the Lower Tagus Valley, one of the largest seismic risk zones of Portugal; and (2) the offshore SW Iberia area, considered to be the source for the 1 November 1755 event (M ∼ 8.7). Results show that some of the earthquake source models should be considered suspicious, given their high/low moment release when compared to the expected values from GNSS observations or neotectonic
modelling. This analysis allowed for a downgrade of the weight of poorly compliant models in the PSHA analysis, and thus for a more realistic hazard
assessment, and can be integrated in other studies of similar settings.
Dam type and lake location characterize ice-marginal lake area change in Alaska and NW Canada between 1984 and 2019
Authors: Rick Brianna , McGrath Daniel , Armstrong William , McCoy Scott W. 
Published: January 2022

Abstract. Ice-marginal lakes impact glacier mass balance, water resources, and ecosystem dynamics and can produce catastrophic glacial lake outburst floods (GLOFs) via sudden drainage. Multitemporal inventories of ice-marginal lakes are a critical first step in understanding the drivers of historic change, predicting future lake evolution, and assessing GLOF hazards. Here, we use Landsat-era satellite imagery and supervised classification to semi-automatically delineate lake outlines for four ∼5-year time periods between 1984 and 2019 in Alaska and northwest Canada. Overall, ice-marginal lakes in the region have grown in total number (+183 lakes, 38 % increase) and area (+483 km2, 59 % increase) between the time periods of 1984–1988 and 2016–2019. However, changes in lake numbers and area were notably unsteady and nonuniform. We demonstrate that lake area changes are connected to dam type (moraine, bedrock, ice, or supraglacial) and topological position (proglacial, detached, unconnected, ice, or supraglacial), with important differences in lake behavior between the sub-groups. In strong contrast to all other dam types, ice-dammed lakes decreased in number (six fewer, 9 % decrease) and area (−51 km2, 40 % decrease), while moraine-dammed lakes increased (56 more, 26 % and +479 km2, 87 % increase for number and area, respectively) at a faster rate than the average when considering all dam types together. Proglacial lakes experienced the largest area changes and rate of change out of any lake position throughout the period of study and moraine-dammed lakes which experienced the largest increases are associated with clean-ice glaciers (<19 % debris cover). By tracking individual lakes through time and categorizing lakes by dam type, subregion, and topological position, we are able to parse trends that would otherwise be aliased if these characteristics were not considered. This work highlights the importance of such lake characterization when performing ice-marginal lake inventories and provides insight into the physical processes driving recent ice-marginal lake evolution.

Published: January 2022

Introduction: Young driver behavior and safety are key concerns in Qatar, where they are disproportionately represented amongst road victims and fatalities. This paper summarizes the proceedings of a workshop, entitled “Enhancing the Safety of Young and Novice Drivers in Qatar”, held as a pre-conference workshop of the 24th World Congress of the International Traffic Medicine Association (ITMA) in Doha, Qatar. Methods: A guided discussion was conducted amongst a selected multi-sectoral group of 50 stakeholders, representing Law Enforcement, Health, Society and Education, Transport, and Road Safety. Each group discussed the best evidence and local realities of young driver safety in the State of Qatar. Using a modified Delphi approach, key areas were identified and prioritized; consensus recommendations were obtained and summarized. Results: Based on the stakeholders’ discussions a list of twelve key recommendations has been developed and its elements have been classified in order of priority. These recommendations are supported by relevant published evidence as well as expert opinion and have been shared with the relevant authorities to inform future policies. Conclusions: This article summarizes the workshop presentations and the twelve key recommendations that arose from the discussions and put them forward to the concerned authorities. It should be emphasized that the concerned authorities concerned need to take action on at least the top three recommendations (GDL, improved police enforcement, and improved licensing and training), but also to prioritize all other recommendations that can be easily addressed such as improved roads and auditing and risk-based insurance.
Survival outcomes of emergency thoracotomy in severely injured patients performed by a general surgeon at a rural university hospital in Thailand
Authors: Tullavardhana Thawatchai 
Published: January 2022

Background: Emergency thoracotomy is a potentially life-saving maneuver for trauma patients in extremis. Since trauma scenarios, in rural locations, usually occur with a high incidence of a severe injury that leads to hemorrhagic shock or cardiopulmonary arrest. The objective of this study was to analyze the experience in emergency thoracotomy performed by a general surgeon in a rural area in Thailand. Methods: This retrospective study was conducted by analyzing the patient records including demographics, mechanisms of injuries, specific organ injury, surgical approach, life-saving surgical procedure, and postoperative outcome for all patients who underwent emergency thoracotomy in the Department of Surgery, Srinakharinwirot University hospital between January 2010 and December 2020. Results: Twelve patients underwent emergency thoracotomy within 1 hour after arrival and were equally divided between blunt and penetrating injuries with 6 (50%). A mean patient age of 34.8 ± 15.2 years (range 16–55), mean systolic blood pressure on arrival was 65.8 ± 35.2 mmHg (range 0–100 mmHg), and the mean injury severity score (ISS) was 54.6 ± 25.2 (range 26–75). Profound hemorrhagic shock is a major indication for emergency thoracotomy. The overall survival rate was 41.7% (5/12 patients) without survivors from cardiac injuries. Four patients (66.7%) in the penetrating and 1 patient (16.7%) in the blunt intrathoracic injury group were survived and discharged from the hospital. Conclusion: Emergency thoracotomy offers a chance for survival at 41.7% for trauma patients who present with extremes in this study. Rapid decision-making, good operative technique, and adequate patient selection are crucial for reasonable outcomes.
A proof of Hall's conjecture on length of ray images under starlike mappings of order α
Authors: Hästö Peter , Ponnusamy Saminathan 
Published: January 2022

Assume that \(f\) lies in the class of starlike functions of order \(\alpha\in[0,1)\), that is, which are regular and univalent for \(|z|<1\) and such that
Re\(\left(\frac{zf'(z)}{f(z)}\right)>\alpha\) for \(|z|<1.\)
In this paper we show that for each \(\alpha\in[0,1)\), the following sharp inequality holds:
\(|f(re^{i\theta})|^{-1}\int_{0}^{r}|f'(ue^{i\theta})|\,du\leq\frac{\Gamma(\frac{1}{2})\Gamma(2-\alpha)}{\Gamma(\frac{3}{2}-\alpha)}\) for every \(r<1\) and \(\theta\).
This settles the conjecture of Hall (1980) positively.

Published: January 2022

Dans de nombreuses disciplines scientifiques, des études expérimentales ou des suivis sur le terrain assurent la récolte de données. Celles-ci sont stockées sur des fichiers bruts avec un format intuitif, permettant une saisie facile par l’expérimentateur. Cependant, ce format brut est rarement directement compatible avec l’analyse des données récoltées et peut engendrer des analyses erronées ; il est nécessaire d’effectuer une mise en forme et un contrôle qualité des données. Face au nombre de jeux de données brutes croissants et toujours plus massifs, la discipline du numérique pour les sciences du vivant s’est développée. La programmation informatique représente une aide précieuse pour les modélisateurs puisqu’elle permet d’automatiser la mise en forme et le contrôle qualité qui nécessitent souvent un nettoyage des données. Dans cet article, nous présentons une collaboration entre informaticien et modélisateur dans le cadre du suivi de l’abondance d’espèces animales. Les données récoltées sur plusieurs feuilles d’un tableur sont regroupées sur une seule et leur qualité est vérifiée. Les diverses fonctionnalités du programme effectuant cette vérification ont été mises en place à l’aide de la méthode « agile », méthode de développement informatique constituée de sprints. Après la fourniture d’une version du programme, un nouveau sprint définit une nouvelle fonctionnalité à mettre en place par l’informaticien dans une nouvelle version du programme. La première version permet l’appropriation du jeu de données par l’informaticien grâce à la fonctionnalité de mise en forme. Une version plus avancée gère l’absence de données, puis d’autres contrôlent la qualité des données récoltées et rapportent le traitement des anomalies détectées – donnée absente ou erronée ou en dehors d’une plage spécifiée – dans un fichier texte. Ce programme informatique a été explicité afin qu’il puisse être ré-approprié et ré-utilisé. Sa version complète est déposée dans GitHub. Le lien est donné en conclusion.
