Published: June 2024

This study evaluates the hematological profile of potential broodstock silver pompano (Trachinotus blochii) through hormonal induction and phyto-biotic supplementation via feed. An experimental trial was conducted for 30 days to assess the hematological profile of potential broodstock Trachinotus blochii. This study employed a completely randomized design (CRD) in two research experiments. The first experiment utilized hormonal induction with estradiol-17β hormone on female silver pompano broodstock, consisting of 3 treatments: E1 (0 mg/kg), E2 (20 mg/kg), and E3 (60 mg/kg), whereas the second experiment employed phyto-biotic induction using Tribulus terrestris extract (ETT) and gonadotropin hormone, consisting of 5 treatments: T1: ETT 0 mg/kg feed, T2: ETT 50 mg/kg feed, T3: ETT 250 mg/kg feed, T4: ETT 50 mg/kg feed + gonadotropin 1000 IU/kg body weight, and T5: ETT 250 mg/kg feed + gonadotropin 500 IU/kg body weight, both experiments used 8 individuals as replicate per treatment. The results of the study indicated that all major hematological indices such as total erythrocytes, total leukocytes, and hematocrit levels were higher in male silver pompano broodstock supplemented with Tribulus terrestris extract compared to female silver pompano broodstock induced hormonally with estradiol-17β hormone.

Published: June 2024

The main objective of the work reported herein was to study the possibility of simultaneous use of microalgae for bioremediation and biodiesel production. Determination of optimum nitrate and phosphate concentrations for the maximum algal growth in the presence of heavy metal ions in the growth media was the other objective. In this regard, Chlorellavulgaris, a microalga, was cultivated separately for 30 days at ~28 °C in the presence and absence of known cadmium, lead, phosphate ion concentrations in growth media containing an optimum nitrate ion concentration. The concentrations of these ions in the growth media, dry algal biomass and extractable algal-oil percentage after 30 days of their growth were determined. According to the study, the optimum total nitrate and total phosphate concentrations required for the maximum algal growth were 200 mg L-1 and 10 mg L-1, respectively. The maximum tolerable Pb2+ and Cd2+ concentrations were 8 mg L-1 and 2.5 mg L-1, respectively. The results revealed that Chlorellavulgaris has a high capacity for both removing these ions (> 70%) from the growth medium, and generating algal biomass, simultaneously. Moreover, the algal biomass generated under these harsh conditions yields algal-oil (~41% in terms of dry algal biomass) that is free from these ions.

Published: June 2024

‘Silvering (slowly)’ was a group show at St Paul Street Gallery in Auckland, NZ, 9–13 September 2019. It drew together threads from our independent research trajectories as a response to this journal’s questions around augmentation and technicity. The exhibition was a material dialogue consisting of installations and drawings, structured dialogues before and during the show, and an epistolary exchange afterwards. 
The operative methodology is one of conversation between collaborators that was conceived more generally as an open-ended material practice including nonhuman participants. Without purporting to offer a single consistent position, we problematise the concept of augmentation through our conversation. By means of our rhetorical figures—the moon, mirrors, silvering hair, and silence—we question the time and matter of augmentation, and its sense of forwardness and addition.

Authors: Багрім Ольга Андріївна
Published: June 2024

У статті розкрито суть та особливості формування позитивного іміджу публічних службовців, досліджено питання напрямів створення, підтримки та удосконалення іміджу публічних службовців в умовах воєнного та післявоєнного періоду в Україні. Доведено, що формування позитивного іміджу публічних службовців є надзвичайно актуальним питанням в контексті процесів реформування, модернізації, трансформації публічної служби, а також налагодженню ефективної тісної взаємодії органів публічної влади з громадянським суспільством у воєнний і післявоєнний період в Україні. Акцентовано увагу на тому, що формування позитивного іміджу публічних службовців в Україні містить ряд специфічних особливостей щодо його побудови, функціонування та підтримки. Визначено негативні явища, які «сповільнюють» процес формування позитивного іміджу публічних службовців, до яких автор пропонує віднести: наявність високого рівня корупції, низький рівень професіоналізму публічних службовців, недостатньо уважне ставлення до існуючих або нагальних інтересів громадян, відсутність зворотнього зв’язку, нестача висококваліфікованих молодих кадрів, використання «застарілих» кадрових технологій розвитку персоналу, низький рівень мотивації публічних службовців, низький рівень розвитку професійного та особистісного потенціалу публічних службовців тощо. Встановлено, що особистісно-професійні, моральні та суспільні норми і принципи є основними складовими для формування позитивного іміджу публічних службовців в умовах воєнного стану і післявоєнного періоду. Формування позитивного іміджу публічної служби безпосередньо залежить від формування іміджу кожного окремого публічного службовця, є результатом безперервної, послідовної та досить складної діяльності, спрямованої на створення, підтримання та посилення позитивної громадської думки. Визначено фактори, які впливають на формування іміджу публічних службовців, запропоновано та аргументовано напрями формування позитивного іміджу публічних службовців в умовах воєнного стану і післявоєнного періоду в Україні. Автором акцентовано увагу на тому, що формування позитивного іміджу публічної служби сприяє зміцненню та підвищенню авторитету державної влади у суспільстві та на міжнародній арені, сприяє захисту загальнонаціональних інтересів, динамічному соціально-економічному розвитку країни тощо.

В сучасних умовах трансформації сім’ї, психологічне розуміння рольових експектацій молоді у структурі сімейних цінностей є актуальним і таким, що потребує емпіричного вивчення. Саме в юнацькому віці усвідомлюються сімейні цінності, експектації та особливі функціонально-рольові стратегії поведінки. Саме в складних і трагічних умовах виживання, сімейні цінності допомагають молоді усвідомити важливість емоційної підтримки та обміну досвіду переборення випробувань, тому актуалізується проблема вивчення експектацій ставлення до сімейних цінностей і збігу уявлень про гендерно-рольову поведінку у сім’ї та її образ у молоді остається поза увагою і потребує вирішення. В статті розглядуються результати психодіагностичного дослідження показників сімейних цінностей, які здатні з'єднувати чинники готовності до шлюбу із рольовими очікуваннями, аналізується їх вплив на сімейні цінності через такі складові як: домагання, розуміння, емоційне тяжіння, авторитетність. Надано аналіз результатів дослідно-емпіричного дослідження складових сімейних цінностей у студентській молоді. Використано методи порівняльного аналізу, узагальнення та індукції, тести і опитувальники. Було з’ясовано, що готовність до шлюбу виступає питомим показником рольових експектацій у структурі сімейних цінностей студентів. Підкреслюється, що юнаки із високим рівнем готовності до шлюбу більше схильні до розуміння і поваги партнера, ідентифікації з ним, орієнтовані на ведення господарства та очікують від партнера активності у вихованні дітей, емоційного контакту і тяжіння та емоційної привабливості у спілкуванні. Натомість, юнаки з низьким рівнем готовності до подружнього життя характеризуються зниженими показниками ідентифікації з партнером, емоційно від нього дистанціюються, не потребують солідарності у розумінні, очікуючи активність у веденні домашнього побуту. та недиференційовані сімейні цінності. Зміна українського суспільства відображається на сім’ї і рольових експектацій молоді, але, слід зазначити, що сімейні цінності та їх структура остаються незмінними.

Published: June 2024

Nos sociétés sont devenues très crisogènes. La gestion de ces crises est un véritable enjeu pour les territoires qui ont souvent des solutions différentes, que ce soit avant, pendant ou après la crise. Il découle souvent de ces crises une forme d’inertie territoriale. Cependant certains innovent, imaginent des territoires renouvelés, préparent la reconstruction, voire recomposent dès maintenant les territoires, afin de les rendre plus résilients.Gestion des crises territoriales explore les crises et les modalités d’anticipation, de gestion et de reconstruction. Il cerne cette notion largement mobilisée et explicite les modalités d’action dans le champ de la gestion des crises, afin de penser un continuum risque-crise-développement territorial. L’ouvrage questionne aussi les différentes formes d’apprentissage proposées pour mieux affronter les crises futures. Il invite enfin à analyser les ressources en appui à la gestion des crises et à la reconstruction pour concevoir des stratégies territoriales à venir. La crise peut en effet être le moteur ou l’accélérateur de ces changements et contribuer à l’émergence de nouvelles pratiques, voire de nouvelles utopies urbaines et territoriales.

Trauma-informed approach for bridging ethnic distance in post-conflict societies
Authors: Kuhar Metka , Bolko Irena , Zupančič Rok
Published: June 2024

The article presents a pilot study based on intervention conducted in Croatia in 2022. Despite intensive peacebuilding efforts, ethnic tensions in post-conflict societies remain high, suggesting that current strategies may be missing critical components. This experiment integrated recent neurophysiological findings, particularly polyvagal theory, into peacebuilding intervention. The intervention involved a two-day seminar in Zagreb, where trauma-informed, body-based techniques were used to address post-war trauma. Participants learnt to recognise and manage trauma reactions by promoting their interoceptive awareness and a felt sense of safety. The seminar included both theoretical and experiential components, focusing on the impact of trauma on the autonomous nervous system and interpersonal dynamics. The study used an experimental design with intervention and control group to investigate the effects of the seminar. Measures included interoceptive awareness, autonomic reactivity, ethnic distance, perspective taking and mental well-being. The results showed that the participants in the intervention group showed significant improvements in interoceptive awareness, particularly in not worrying and emotional awareness subscales compared to the control group. However, ethnic distance scores did not decrease as expected, highlighting the complexity of changing deep-rooted attitudes. The study faced some challenges, including participant recruitment and the short duration of the intervention, which may have limited its effectiveness. Despite these limitations, the findings suggest that integrating trauma-informed approaches into peacebuilding efforts holds promise for improving interethnic relations. Future research should focus on longer interventions and diverse participant groups to better understand the potential of these methods in various contexts.
Observed impact of the GNSS clock data rate on Radio Occultation bending angles for Sentinel-6A and COSMIC-2

Abstract. Space-based Radio Occultation (RO) experiments currently require the tracking of signals from the Global Navigation Satellite System (GNSS) by a Low-Earth-Orbit (LEO) satellite as the signals travel through different layers of the atmosphere. The orbit and clock solutions for the GNSS constellations affect these experiments in two ways: They are needed to obtain a zero-differencing GNSS-based orbit and clock solution for the LEO, and they enter directly the processing of each single radio occultation profile, where the orbit and clock information for the transmitter (GNSS satellite) and receiver (LEO) is required. In this work, we investigate how different GLONASS and GPS orbit and clock solutions affect the statistical properties of RO profiles by comparing our results with forward-modelled bending angle profiles obtained from the European Centre for Medium-Range Weather Forecasts (ECMWF) short-range forecasts. Given that GNSS orbits are relatively smooth, the focus will be on the effect of different transmitter clock data rates, and we tested the range from 1 to 30 seconds. The analysis is based on the reprocessing of Sentinel-6A data (four months in 2021, or about 110k occultations) and of a smaller sample of recent COSMIC-2/FORMOSAT-7 data (about 9k occultations). We find that at impacts heights above about 35 km GLONASS bending angles statistics markedly improve with the use of high-rate clock information. For GPS, not much is gained by using rates higher than 30 s, and the statistics are better for more recent GPS blocks. These results are likely the manifestation of the different short-timescale behaviour of the atomic clocks onboard the GPS and GLONASS constellations.

Abstract. This study introduces the primary products and features of active sensor-based Level 2 cloud products of the Japanese Aerospace Exploration Agency (JAXA). Combined with 94 GHz Doppler cloud radar and 355-nm high-spectral-resolution lidar, these products provide a detailed view of the transitions of cloud particle categories and their size distributions, as well as vertical velocity information. Simulated EarthCARE Level 1 data mimicking actual global observations were used to assess the performance of the JAXA Level 2 cloud product. Evaluation of the product revealed that the retrievals reasonably reproduced the vertical profile of the modelled microphysics. Further validation of the products is planned for after-launch calibration/validation. JAXA Level 2 velocity-related products will be described in a future paper.
A Python interface to the Fortran-based Parallel Data Assimilation Framework: pyPDAF v1.0.0
Authors: Chen Yumeng , Nerger Lars , Lawless Amos S.
Published: June 2024

Abstract. Data assimilation (DA) is an essential component of numerical weather and climate prediction. Efficient implementation of DA benefits both operational prediction and research. Currently, a variety of DA software programs are available. One of the notable DA libraries is the Parallel Data Assimilation Framework (PDAF) designed for ensemble data assimilation. The DA framework is widely used with complex high-dimensional climate models and is applied for research on atmosphere, ocean, sea ice and marine ecosystem modelling, as well as operational ocean forecasting. Meanwhile, there exists increasing need for flexible and efficient DA implementations using Python due to the increasing amount of intermediate complexity models as well as machine learning based models coded in Python. To accommodate for such needs, here, we introduce a Python interface to PDAF, pyPDAF. The Python interface allows for flexible DA system development while retaining the efficient implementation of the core DA algorithms in the Fortran-based PDAF. The ideal use-case of pyPDAF is a DA system where the model integration is independent from the DA program, which reads the model forecast ensemble, produces a model analysis and update the restart files of the model, or a DA system where the model can be used in Python. With implementations of both PDAF and pyPDAF, this study demonstrates the use of pyPDAF and PDAF for coupled data assimilation (CDA) in a coupled atmosphere and ocean model, the Modular Arbitrary-Order Ocean-Atmosphere Model (MAOOAM). Using both weakly and strongly CDA, we demonstrate that pyPDAF allows for the utilisation of Python-based user-supplied functions in the Fortran-based DA framework. We also show that the Python-based user-supplied routine can be a main reason for the slow-down of the DA system based on pyPDAF. Our CDA experiments confirm the benefit of strongly coupled data assimilation compared to the weakly coupled data assimilation. We also demonstrate that the CDA not only improves the instantaneous analysis but also the long-term trend of the coupled dynamical system.
Temporal dynamic vulnerability – Impact of antecedent events on residential building losses to wind storm events in Germany
Authors: Trojand Andreas , Rust Henning , Ulbrich Uwe
Published: June 2024

Abstract. Severe winter storm events are one of Central Europe's most damaging natural hazards, therefore particularly in focus for disaster risk management. One key factor for risk is vulnerability. Risk assessments often assume vulnerability as constant. This is, however, not always a justifiable assumption. This work seeks and quantifies a potential dynamic of vulnerability for residential buildings in Germany. A likely factor affecting the dynamics of vulnerability is the hazard itself. As an extreme events may destroy the most vulnerable elements, it is likely that the subsequent rebuilding or repair will reduce their vulnerability for following events. Therefore, the intensity of the previous events and the resulting damage can be assumed to be a decisive factor in changing vulnerability. A second important factor is the time period between the previous and current event. If the next event occurs during the reconstruction phase, vulnerability might be higher than when the reconstruction phase is completed. We analyze the role of previous storm events for the vulnerability of residential buildings. For this purpose, generalized additive models are implemented to estimate vulnerability as a function of the intensity of the previous event and the time interval between the events. The damage is extracted from a 23-year-long data set of the daily storm and hail losses for insured residential buildings in Germany on the administrative district level provided by the German Insurance Association, and the hazard component is described by the daily maximum wind load calculated from the ERA5 reanalysis. The results show a negative relationship between the previous event's intensity and the current event's damage. The duration between two events shows a significant reduction of the damage for events occurring one or more winter seasons ago compared to events occurring within the same season. On a daily scale, the first five to ten days are especially crucial for vulnerability reduction.

Abstract. We present data from ﬂights of two improved ion mass spectrometers in the mesosphere and lower thermosphere region. The instruments were optimized to detect large ion masses of up to m/z 2000 and 20000 respectively, for analysis of meteor smoke particles. The ﬂights were performed in the frame of the PMWE campaign, initiated and coordinated by IAP/Kühlungsborn, to investigate polar mesospheric winter radar echoes in Andøya/Norway in 2018 and 2021. Both ﬂights were successful and allow to investigate the mass number and chemical composition of charged meteor smoke particles. We found a complex and divers composition of positively and negatively charged molecules and particles. While at altitudes below 85 km we observed negatively charged particles of up to several thousands of atomic mass units, above this altitude we found possible building blocks of these large particles that form right after their ablation from the parent meteorite material. While in the ﬁrst ﬂight we detected no positively charged molecules and ion clusters above m/z 100, we measured positive and negative ions with masses up to around m/z 400 in the second ﬂight. Due to the very large mass range of m/z 20000 used in the second ﬂight and the subsequent lower mass resolution, unambiguous mass identiﬁcation is not possible. Comparing our ﬁndings to proposed meteor smoke particle compounds by other authors, our observations would be consistent with Magnetite, Fayalite and Forsterite. However, other possible compounds cannot be excluded.

Abstract. Short-term, episodic atmospheric warming events over Antarctica have received considerable attention for their direct role in establishing record-high temperatures, surface melting, and their indirect impacts via associated high wind speed and precipitation. However, there is limited knowledge of the effect of these warming events on the ice sheet surface and subsurface temperatures, despite their critical role in firn microphysical properties. Using reanalysis dataset ERA5 and ice sheet surface and subsurface temperature records from an ice core-borehole (71.5 °S, 10.25 °E) from coastal Dronning Maud Land (cDML), we examined the air (T2m) warming, subsurface warming, regional and large scale drivers of 70 short term ice sheet surface warming (ISSW) events covering a period 2014–2018. Out of 70 ISSW events, 60 occurred during periods of strong easterly winds with high snow accumulation and the rest during strong southeasterly winds (katabatic) without any precipitation. The former events resulted from increased downward longwave radiation and warmer air above associated with warm air advection from cyclonic intrusions. With an average frequency of 12 events/year, they established the highest ISSW over the region including the maximum warming of ~11 °C raising the ISST from -34 °C to -25 °C (in 9 days) recorded over the period and penetrating deeper in the snowpack (40–125 cm). Here, the T2m showed a minimum warming of 4.4 °C and a maximum of 24.6 °C, leading the ISSW by two days. The latter events were associated with turbulent mixing from strong, dry and anomalously warm winds from the interior. Although the T2m warmed significantly (4.4–15 °C) without any lead/lag, these events showed modest ISSW (2–5 °C) and shallow heat penetration to snowpack (40–60 cm) but resulted in significant sublimation over the region. Our study suggests that the impact of atmospheric warming events on ice sheet surface and subsurface temperatures varies with meteorological conditions. The frequent occurrence of these events might alter the firn's water-retaining capacity, which becomes crucial when surface melting reaches beyond the grounding line in a continued warming scenario. In the future, it is anticipated that their effects will increase as greenhouse gas concentrations rise.

Abstract. The highly sensitive Ka-band cloud radar at the Barbados Cloud Observatory (BCO) frequently reveals radar reflectivities below -50 dBZ within updrafts and below the cloud base of cumulus clouds. These so-called haze echoes are signals from hygroscopically grown sea salt aerosols. Within the Cloudnet target classification scheme, haze echoes are generally misclassified as precipitation ("Drizzle or rain"). We present a technique to discriminate between "Drizzle or rain" and sea salt aerosols in Cloudnet that is applicable to marine Cloudnet sites. The method is based on deriving heuristic probability functions utilizing a combination of cloud radar reflectivity factor, radar mean Doppler velocity and ceilometer attenuated backscatter coefficient. The method is crucial for investigating the occurrence of precipitation and significantly improves the Cloudnet target classification scheme for the measurements over the BCO. The results are validated against the amount of precipitation detected by the Virga-Sniffer tool. We analyze data for the measurements in the vicinity of the BCO covering two years (July 2021–July 2023) as well as during the ElUcidating the RolE of Cloud–Circulation Coupling in ClimAte (EUREC4A) field experiment that took place in Jan–Feb 2020. A first-ever statistical analysis of the Cloudnet target classification product including the new "haze echo" target over two years at the BCO is presented. In the atmospheric column above the BCO, “Drizzle or rain" is on average more frequent during the dry season compared to the wet season, due to the higher occurrence of warm clouds contributing to the amount of precipitation. Haze echoes are identified about four times more often during the dry season compared to the wet season. The frequency of occurrence of "Drizzle or rain" in Cloudnet caused by misclassified haze echoes is overestimated by up to 16 %. Supported by the Cloudnet statistics and the results obtained from the Virga-Sniffer tool, 48 % of detected warm clouds in the dry and wet season precipitate. The proportion of precipitation evaporating fully before reaching the ground (virga) is higher during the dry season. During EUREC4A, precipitation from warm clouds was found to reach the ground more frequently over the RV Meteor compared to the BCO.

Abstract. The Comprehensive Air quality Model with extensions (CAMx) is an open-source, state-of-the-science photochemical grid model that addresses tropospheric air pollution (ozone, particulates, air toxics) over spatial scales ranging from neighborhoods to continents. CAMx has been in continuous development for over 25 years and used by numerous entities ranging from government to industry to academia to support regulatory actions and scientific research addressing a variety of air quality issues. Here we describe the technical formulation of CAMx v7.20, the current publicly available model version. To illustrate an example of regional and seasonal model performance for predicted ozone and fine particulate matter (PM2.5), we summarize a model evaluation from a recent 2016 national-scale CAMx application over nine climate zones contained within the conterminous US. From that evaluation, we find that statistical performance for warm season maximum 8-hour ozone is consistently within benchmark statistical criteria for bias, gross error, and correlation over all climate zones, and often near statistical goals. Statistical performance for 24-hour PM2.5 and constituents fluctuate around statistical criteria with more seasonal and regional variability that can be attributed to different sources of uncertainty among PM2.5 species (e.g., weather influences, chemical treatments and interactions, emissions uncertainty, and ammonia treatments). We close with a mention of new features and capabilities that will be included in upcoming public releases of the model.
Triangulated Irregular Network based Seamline Determination for Fast Image Stitching of Multiple UAV Images

Published: June 2024

Abstract. To maintain the efficiency of UAV (unmanned aerial vehicle) remote sensing, rapid image stitching is essential to make multiple UAV images into a seamless mosaic image. Relief displacement introduces variations in object appearance for each image, causing mismatch errors at mosaic seamlines. Traditional approaches involve orthorectifying images using DSMs (digital surface models). While these approaches allow for accurate image stitching, they do not cope with the advantages of UAVs due to their time consumption. In contrast, fast image stitching techniques that do not use orthorectification are well suited for UAV image processing. Related researches have attempted to optimize seamlines to eliminate the errors caused by relief displacement without the use of DSMs. We propose to utilize a TIN (triangular irregular network) of tiepoints to effectively eliminate errors caused by relief displacement while maintaining the fast speed of image stitching. In this study, a TIN is constructed based image tiepoints whose ground coordinates have been obtained through bundle adjustment. The edges of the TIN are used to generate seamlines for image stitching, and the facets of the TIN are used to select minimal images for image stitching and to optimize seamlines. Image stitching results of our proposed method had small error of 1–2 pixels and the processing time of less than 10 minutes for 97 UAV images. This study showed that the proposed method could stitch multiple images while maintaining stable quality using only geometric clues of a TIN of tiepoints.
