Published: July 2024

The aim of this study is evaluate the effects of domestic detergents in the digestive gland, embryonic development and in the reproduction of M. olfersi. Prawns were maintained in two tanks with 21.5 L of deionized-water: the experimental (tank I) and the control (tank II). One dose of 0.075% of domestic detergent was added to the tank I, and the prawns were monitored on 140th exposure day. During this time, the gonadal maturation was monitored, the eggs were removed from the ovigerous females and measured. Development was characterized through of external morphology of the embryos in each incubation day. Females from the two tanks were cooled and the hepatopancreas and ovaries were dissected and fixed in Bouin (24 h), embedded in paraffin and sectioned (8 μm). Both organs were stained with HE and the hepatopancreas was also stained with Hoescht 33258. The results show that the secretory region of hepatopancreas (tank II) present tubules constituted by B-cells with an evident vacuolar apparatus. The animals exposed to detergent showed a decrease in the number of B-cells and significant reduction of vacuolar apparatus. In the experimental group was observed a reduction in the embryonic development time from 14 days in control group to 11 days in the experimental group. The egg volume of germinal-disk stage and final post-nauplius (tank I) were 0.045 and 0.067 mm3 , respectively and the egg volume of the control was, in the same embryonic stages, 0.044 and 0.075 mm3 , respectively. These results suggest that the domestic detergent have a negative effect on the reproductive performance of M. olfersi.

Published: July 2024

Our study explores peoples’ visions of surveillance and resistance to surveillance, enabled through communication and digital platforms in Europe. The research involves future scenario development and analysis, which allows us to sketch out future outlooks concerning surveillance/resistance in Europe, examining how these visions reflect the main assumptions, fears and hopes about the future of societies in Europe. The analysis, which is anchored in surveillance studies, shows how the visions of surveillance and resistance are informed by people’s dispositions towards technology, which centre around techno-optimism and techno-pessimism, focusing either on the empowering or liberating forces of technology or on technology’s disabling and destructive power. These dispositions instruct ideas about the futures of Europe, seeing Europe as either a regulator or protector of people’s privacy and freedoms or as a surveillant apparatus, curtailing peoples’ freedom and democratic rights.

Toxoplasmosis is an infectious disease, the causative agent of which is Toxoplasma gondii - the simplest, intracellular parasite, which infects up to a third of the world’s population.

Clinical manifestations of toxoplasmosis in immunocompetent patients are characterized by lymphadenopathy syndrome, high level of specific antibodies and a favorable outcome. At the same time, the enlargement of the lymph nodes requires a multidimensional differential diagnosis to exclude other diseases.

The article presents a clinical case of toxoplasmosis in a woman with lymphadenopathy. The role of the histological evaluation in the study of biopsy of the lymph nodes in toxoplasmosis was demonstrated. The analysis of literature sources, clinical data, results of laboratory and instrumental studies was carried out.

Sulfentrazone is one of the main pre-emergent herbicides used in tobacco plantations. The objective of this work was to evaluate the selectivity and efficiency of sulfentrazone-based formulations in two tobacco production systems (conventional tillage system [CTS] and no-tillage system [NTS]). Two experiments were conducted (CTS and NTS) in a randomized block design, with seven treatments and four replications. The herbicide treatments were: T1 = Boral® 500 SC (400 g∙ha-1 of sulfentrazone), T2 = PonteiroBR® (400 g∙ha-1 of sulfentrazone), T3 = Stone® (350 + 700 g∙ha-1 of sulfentrazone and diuron, respectively), T4 = Boral® 500 SC + Gamit® 360 CS (792 g∙ha-1 of clomazone), T5 = PonteiroBR® + Gamit® 360 CS, T6 = Stone® + Gamit® 360 CS, and T7 = control (manual weeding). Phytotoxicity in tobacco plants and weed control efficiency were visually evaluated 14, 28, 42, and 56 days after application (daa) of the treatments. Emerged weed plants per m2 were counted 56 daa. Tobacco yield was evaluated by determining the yield per third of the plant (lower, middle, and upper thirds) and the total yield (sum of the yields from each third). The sulfentrazone formulations were efficient in weed control. The herbicide Stone® applied alone or mixed with Gamit® caused mild phytotoxicity in plants under NTS, but no yield losses. No significant difference was found in yield among treatments; however, the yield of the upper third of the plant was higher for plants under NTS, affecting the total yield. The sulfentrazone formulations used provided efficient weed control and selectivity to tobacco plants. The use of NTS resulted in higher yields.
Identity Politics and the Literary Canon: Sándor Márai’s Place in the Hungarian Literary Canon
Authors: Garbacik-Balakowicz Magdalena
Published: July 2024

The paper examines the place of Sándor Márai (1900–1989) in the Hungarian literary canon, specifically, in the context of the discussion on the canon and national identity in the former Eastern Bloc countries after 1989. It draws on the understanding of the canon as a tool used to propagate a certain model of identity within a given society and shows how Márai’s work has been used in socio-political debates at different periods of his career and posthumously. The paper offers a historical perspective and analyses the different stages of Márai’s career: the path to recognition by critics and readers in the 1930s and 1940s, the period of the communist anti-Márai campaign, the period of exclusion from the literary canon, and the great comeback in the 1990s. The paper points to the main aspects that have affected Márai’s reception, and outlines the reasons behind the objections to his oeuvre. The analysis indicates the social, political and historical contexts that affect the different (re)interpretations of Márai’s work and his place in the canon. The paper concludes that, despite the writer’s posthumous literary comeback and international success, his place in the Hungarian literary canon has not been established yet; therefore, it is necessary to take a fresh approach to his work.
Two Canonical Soviet Authors in the Post-Soviet Lithuanian School System: Petras Cvirka and Salomėja Nėris

Published: July 2024

The article examines the place of two Lithuanian writers, Salomėja Nėris (1909–1947) and Petras Cvirka (1904–1945), in the high school canon of Lithuanian literature in the post-Soviet period. First, the canonisation of these writers in the Soviet Lithuanian school system is analysed, or more precisely, in school curricula and textbooks from that time. Afterwards, we examine the revision of their canonical position after the restoration of Lithuania’s independence (1990). The research applies the socio-cultural methodological approach of canon research. A large sample of sources is used: school curricula, textbooks, readers, press publications, and other contextual materials. The study has revealed the different evaluation of Nėris and Cvirka in post-Soviet schools, which is largely due to differences in writers’ biographies. Since Cvirka consistently held and expressed left-wing and later pro-Soviet views in his work throughout his life, his oeuvre gradually disappeared from the upper school curriculum as the de-sovietisation of Lithuanian culture took place in the late 20th and early 21st centuries. Nėris, on the contrary, has retained her central position in the school canon in the post-Soviet period. When her last collection of poems was first published in the late 20th century, in the order Nėris’ herself had wanted, it became possible to reposition certain aspects of her life and work.

Service quality is considered critical to any modern business because it contributes to higher customer satisfaction, business profitability, and improved customer loyalty. The research aimed to determine the service quality management practices of a coffee shop. The study employed a mixed-methods approach, combining descriptive-quantitative and qualitative research methods to comprehensively analyze the coffee shop’s service quality management practices. The respondents involved were college students from a university who were purposively selected based on their familiarity with the coffee shop’s services and willingness to provide feedback on service quality. Findings reveal that while the coffee shop demonstrates commendable service quality management practices in reliability, tangibility, empathy, and responsiveness, it shows gap in assurance. Despite consistently exceeding customer expectations, ongoing improvement in day-to-day service delivery is needed to further enhance the overall customer experience. Coffee shops face various challenges in meeting customer satisfaction, including anticipating and exceeding customer demands, prompt issue resolution, ensuring accessible layouts, demonstrating empathy, and handling complaints professionally. Overcoming these challenges requires unwavering commitment from both management and staff to consistently deliver exceptional service and cultivate enduring customer loyalty. Implementing key recommendations based on the SERVQUAL framework, such as prioritizing customer feedback, continuous staff training, and maintaining service standards, can significantly enhance service quality and lead to a more satisfying customer experience.

Published: July 2024

Stunting is a disorder of growth and development of children due to chronic malnutrition and repeated infections, which are characterized by their length or height being below standard. Malnutrition-free children are a commitment with the world, including Indonesia. The international world's commitment, contained in the second point of the Sustainable Development Goals, emphasizes the importance of "ending hunger, achieving food security and improving nutrition, and promoting sustainable agriculture". To achieve this goal, tackling the problem of malnutrition, including malnutrition, needs to be improved. Toddlers with malnutrition have short and long term impacts, in the form of growth and development disorders, including impaired cognitive function, morbidity, risk of degenerative diseases in the future and death. Stunting can be prevented early on during pregnancy, one of the interventions is good nutrition during pregnancy. Knowledge of nutrition during pregnancy isimportant for pregnant women to prevent stunted children from being born. Many pregnant women do not pay attention to nutritional intake during pregnancy so that their child can be born with stunting. Therefore, every pregnant woman must know about good nutritional intake during pregnancy to prevent stunting.

Technical note: Retrieval of the supercooled liquid fraction in mixed-phase clouds from Himawari-8 observations
Authors: Wang Ziming , Letu Husi , Shang Huazhe , Bugliaro Luca
Published: July 2024

Abstract. The supercooled liquid fraction (SLF) in mixed-phase clouds (MPCs) is an essential variable of cloud microphysical processes and climate sensitivity. However, the SLF is currently calculated in spaceborne remote sensing only as the cloud phase–frequency ratio of adjacent pixels, which results in a loss of the original resolution in observations of cloud liquid or ice content within MPCs. Here, we present a novel method for retrieving the SLF in MPCs based on the differences in radiative properties of supercooled liquid droplets and ice particles at visible (VIS) and shortwave infrared (SWI) channels of the geostationary Himawari-8. Liquid and ice water paths are inferred by assuming that clouds are composed of only liquid or ice, with the real cloud water path (CWP) expressed as a combination of these two water paths (SLF and 1-SLF as coefficients), and the SLF is determined by referring to the CWP from Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO). The statistically relatively small cloud phase spatial inhomogeneity at a Himawari-8 pixel level indicates an optimal scene for cloud retrieval. The SLF results are comparable to global SLF distributions observed by active instruments, particularly for single-layered cloud systems. While accessing the method's feasibility, SLF averages are estimated between 74 % and 78 % in Southern Ocean (SO) stratocumulus across seasons, contrasting with a range of 29 % to 32 % in northeastern Asia. The former exhibits a minimum SLF around midday in summer and a maximum in winter, while the latter trend differs. This novel algorithm will be valuable for research to track the evolution of MPCs and constrain the related climate impact.
Terrestrial runoff is an important source of biological INPs in Arctic marine systems

Published: July 2024

Abstract. The accelerated warming of the Arctic manifests in sea ice loss and melting glaciers, significantly altering the dynamics of marine biota. This disruption in marine ecosystems can lead to the emission of biological ice nucleating particles (INPs) from the ocean into the atmosphere. Once airborne, these INPs induce cloud droplet freezing, thereby affecting cloud lifetime and radiative properties. Despite the potential atmospheric impacts of marine INPs, their properties and sources remain poorly understood. Analysing sea bulk water and the sea surface microlayer in two southwest Greenlandic fjords, collected between June and September 2018, and investigating the INPs along with the microbial communities, we could demonstrate a clear seasonal variation in the number of INPs and a notable input from terrestrial runoff. We found the highest INP concentration in June during the late stage of the phytoplankton bloom and active melting processes causing enhanced terrestrial runoff. These highly active INPs were smaller in size and less heat-sensitive than those found later in the summer and those previously identified in Arctic marine systems. A negative correlation between salinity and INP abundance suggests freshwater input as sources of INPs. Stable oxygen isotope analysis, along with the strong correlation between INPs and the presence of the bacterium Aquaspirillum arcticum, highlighted meteoric water as the primary origin of the freshwater influx, suggesting that the notably active INPs originate from terrestrial sources such as glacial and soil runoff.
Precise dating of deglacial Laptev Sea sediments via 14C and authigenic 10Be/9Be – assessing local 14C reservoir ages

Published: July 2024

Abstract. Establishing accurate chronological frameworks is imperative for reliably identifying lead-lag dynamics within the climate system and enabling meaningful inter-comparisons across diverse paleoclimate proxy records over long time periods. Robust age models provide a solid temporal foundation for establishing correlations between paleoclimate records. One of the primary challenges in constructing reliable radiocarbon-based chronologies in the marine environment is to determine the regional marine radiocarbon reservoir age correction. Calculations of the local marine reservoir effect (ΔR) can be acquired using 14C-independent dating methods, such as synchronization with other well-dated archives. The cosmogenic radionuclide 10Be offers such a synchronization tool. Its atmospheric production rate is controlled by the global changes in the cosmic ray influx, caused by variations in solar activity and geomagnetic field strength. The resulting fluctuations in the meteoric deposition of 10Be are preserved in sediments and ice cores and can thus be utilized for their synchronization. In this study, for the first time, we use the authigenic 10Be/9Be record of a Laptev Sea sediment core for the period 8–14 kyr BP and synchronize it with the 10Be records from absolutely dated ice cores. Based on the resulting absolute chronology, a benthic ΔR value of +345 ± 60 14C years was estimated for the Laptev Sea, which corresponds to a marine reservoir age of 848 ± 90 14C years. The ΔR value was used to refine the age-depth model for core PS2458-4, establishing it as a potential reference chronology for the Laptev Sea. We also compare the calculated ΔR value with modern estimates from the literature and discuss its implications for the age-depth model.

The Mercury Electron Analyzer (MEA) obtained new electron observations during the first threeMercury swingbys (MSBs) by BepiColombo on 01 October 2021 (MSB1), 23 June 2022 (MSB2),and 19 June 2023 (MSB3). We identify the magnetospheric boundaries and describe the structure and dynamics of the electron populations observed in the various regions explored along the swingby trajectories. We compare and contrast our new BepiColombo electron observations with those obtained from the Mariner 10 Scanning Electron Spectrometer (SES) 50 years ago.A comparison to the averaged magnetospheric boundary crossings by MESSENGER indicatesthat the magnetosphere of Mercury was compressed during MSB1, close to its average stateduring MSB2, and highly compressed during MSB3. Our new MEA observations revealed asignificant dusk-dawn asymmetry in electron fluxes on the nightside magnetosphere, and ofstrongly fluctuating electrons with energies above 100s eV on the dawnside magnetosphere.Magnetospheric electron densities and temperatures were in the range of 10-30 cm⁻³ and above a few 100s eV in the pre-midnight-sector, and in the range of 1-100 cm ⁻³ and well below 100 eV in the post-midnight sector, respectively.MEA electron observations of different solar wind properties encountered during the first threeMSBs revealed the highly dynamic response of the solar wind-magnetosphere interactions atMercury. A good match is found between the electron plasma parameters derived by MEA in the various regions of the Hermean environment with similar ones derived for a few cases from other instruments on board BepiColombo.

Abstract. The roadmap to enable operational soil moisture (SM) monitoring for meteorologic and hydrological early warning is challenged by the uncertainty within the available remote sensing and modelling products. This study addressed two relevant uncertainties: the residual trends in the series and the spatial consistency. While the latter has been often revisited to validate remote sensing and modelling products against in-situ data, the former is often disregarded in studies addressing SM changes. This study evaluated three SM products: (1) the Satellite Application Facility on Support to Operational Hydrology and Water Management (H SAF) active Advanced SCATterometer (ASCAT)-derived dataset, (2) the passive subset of the European Space Agency (ESA) - Climate Change Initiative (CCIp), and (3) the modelled dataset from the European Drought Observatory (EDO). The analysis was carried out over Europe in the period 2007–2022 at 10-day temporal scales. We obtained that even these popular datasets are subject to patches of spatial inconsistency and residual trends when compared to the in-situ data from the International Soil Moisture Network (ISMN). In view of the great complementarity shown by the active and passive remote sensing and the modelled SM estimates, two merged products are proposed and tested against in-situ data. Results indicate that combining H SAF ASCAT, CCIp and EDO equals or surpasses the spatial and temporal consistency of the individual SM products alone, even when only the near-real-time products of H SAF ASCAT and EDO are combined. Thus, merging remote sensing and modelled SM products is advantageous for enhanced spatial and temporal operational monitoring of SM at the European scale.

Abstract. The National Water Model (NWM) provides critical analyses and projections of streamflow that support water management decisions. However, the NWM performs poorly in lower-elevation rivers of the western United States (US). The accuracy of the NWM depends on the fidelity of the model inputs and the representation and calibration of model processes and water sources. To evaluate the NWM performance in the western US, we compared observations of river water isotope ratios (18O / 16O and 2H / 1H expressed in δ notation) to NWM-flux-estimated (model) river reach isotope ratios. The modeled estimates were calculated from long-term (2000–2019) mean summer (June, July, and August) NWM hydrologic fluxes and gridded isotope ratios using a mass balance approach. The observational dataset comprised 4503 in-stream water isotope observations in 877 reaches across 5 basins. A simple regression between observed and modeled isotope ratios explained 57.9 % (δ18O) and 67.1 % (δ2H) of variance, although observations were 0.5 ‰ (δ18O) and 4.8 ‰ (δ2H) higher, on average, than mass balance estimates. The unexplained variance suggest that the NWM does not include all relevant water fluxes to rivers. To infer possible missing water fluxes, we evaluated patterns in observation–model differences using δ18Odiff (δ18Oobs−δ18Omod) and ddiff (δ2Hdiff-8⋅δ18Odiff). We detected evidence of evaporation in observations but not model estimates (negative ddiff and positive δ18Odiff) at lower-elevation, higher-stream-order, arid sites. The catchment actual-evaporation-to-precipitation ratio, the fraction of streamflow estimated to be derived from agricultural irrigation, and whether a site was reservoir-affected were all significant predictors of ddiff in a linear mixed-effects model, with up to 15.2 % of variance explained by fixed effects. This finding is supported by seasonal patterns, groundwater levels, and isotope ratios, and it suggests the importance of including irrigation return flows to rivers, especially in lower-elevation, higher-stream-order, arid rivers of the western US.

Abstract. Here, we present observations of temporal variability of sub-ice platelet layer over seasonal and diurnal timescales under Ice Shelf Water-influenced fast ice in McMurdo Sound. Electromagnetic induction (EM) sounding time-series measurements of the thicknesses of fast ice and sub-ice platelet layer were made in winter and late spring of 2018. Winter objectives were to measure the seasonal growth of fast ice and sub-ice platelet layer near the McMurdo Ice Shelf in the east, while in late spring we assessed the diurnal variability of sub-ice platelet layer with coincident EM time-series and oceanographic measurements collected in the main outflow path of supercooled Ice Shelf Water in the west. During winter, we observed when the sub-ice platelet layer formed beneath consolidated ice. Episodes of rapid sub-ice platelet layer growth (∼ 0.5–1 m) coincided with strong southerly wind events and polynya activity, suggesting wind-enhanced Ice Shelf Water circulation from the McMurdo–Ross Ice Shelf cavity. In late spring, we investigated how the tides and ocean properties influenced the sub-ice platelet layer. Over a 2-week neap–spring tidal cycle, changes in sub-ice platelet layer thickness were observed to correlate with the tides, increasing more during neap than spring tide cycles, and on diurnal timescales, more on ebb than flood tides. Neap and ebb tides correspond with stronger northward circulation out of the cavity, indicating that sub-ice platelet layer growth was driven by tidally enhanced Ice Shelf Water outflow. The observed variability indicated that wind-driven circulation and the tides influence Ice Shelf Water outflow in McMurdo Sound and, consequently, sub-ice platelet layer evolution over a range of timescales.

Abstract. Accurate snow cover modeling is a high-stakes issue for mountain regions. Alpine snow evolution and spatial variability result from a multitude of complex processes including interactions between wind and snow. The SnowPappus blowing snow model was designed to add blowing snow modeling capabilities to the SURFEX/Crocus simulation system for applications across large spatial and temporal extents. This paper presents the first spatialized evaluation of this simulation system over a 902 km2 domain in the French Alps. Here we compare snow cover simulations to the spatial distribution of snow height obtained from Pléiades satellites stereo imagery and to snow melt-out dates from Sentinel-2 and Landsat 8 time series over three snow seasons. We analyzed the sensitivity of the simulations to three different precipitation datasets and two horizontal resolutions. The evaluations are presented as a function of elevation and landform types. The results show that the SnowPappus model forced with high-resolution wind fields enhances the snow cover spatial variability at high elevations allowing a better agreement between observed and simulated spatial distributions above 2500 m and near peaks and ridges. Model improvements are not obvious at low to medium altitudes where precipitation errors are the prevailing uncertainty. Our study illustrates the necessity to consider error contributions from blowing snow, precipitation forcings, and unresolved subgrid variability for robust evaluations of spatialized snow simulations. Despite the significant effect of the unresolved spatial scales of snow transport, 250 m horizontal-resolution snow simulations using SnowPappus are found to be a promising avenue for large-scale modeling of alpine snowpacks.
