Behavior of Cubaris murina Brandt (Crustacea: Isopoda) in Soil Contaminated With Glyphosate: Avoidance Tests in Laboratory
Authors: Niemeyer Júlia Carina , Santos V. C. dos , Rodrigues J. M. L. , Da-Silva E. M.
Published: July 2024

Acute tests and avoidance tests were carried out using laboratory populations of Cubaris murina, to assess their sensibility to glyphosate. The contaminant solutions were prepared by herbicide Roundup®. In the acute tests, ten offspring were confined and exposed to each treatment: soil with different concentrations of glyphosate and soil without contaminant (control). Mortality was observed after 7 days. The Spearman-Karber test was used to calculate the LC50 . In the avoidance tests, ten juveniles were put on the center of each recipient-test, with four portions of soil: three portions with different concentrations of glyphosate and one control. The preference of the isopods was registered after 1.5, 2, 3, 4 and 24 hours. ANOVA was used to verify whether there were significant differences among the mean number of isopods in each treatment and the control. The 7-d-LC50 was 35.5 mg gli/g soil. In the avoidance tests, significant differences (p < 0.05) in relation to the control, which indicated avoidance, occurred in all treatments, including 5.12 mg gli/g soil, already at 1.5 hour. The avoidance behavior was a very sensitive endpoint, assessed in low cost experiments, showing a rapid response and having an important ecological role.

Published: July 2024

The pollution of the aquatic ecosystem has been increasing in the last years, mainly due to the industrial and agricultural development. The Atrazine pesticide is an important agent pollutant and it can harm the development and reproduction of several species of fish due to its toxicity. Piaractus mesopotamicus (pacu) is one of the species thoroughly comercialized and used in fish farms. The present study analyzed possible modifications in the concentration of ions in the plasma (Na+, Cl–, K+, Ca2+), in the blood pH and in the micronucleus frequency in pacu erythrocytes (N = 10 for group; Wt: 160.0 ± 5 g) exposed to the Atrazine herbicide (0.1 mg/L) during 96 hours in semi-static system. Samples of blood were collected, with aid of syringes heparinized, being centrifuged later and/or made smears for subsequent analysis of the micronucleus. The obtained plasma was used for the determinations of ions in the plasma. Cytological analyses showed significant differences (p < 0.0001) in the micronucleus frequency among the control group which was exposed to the atrazine herbicide. The blood pH stayed constant, but the ions concentration in the plasma Na+ and Cl– was, in relation to the control, significantly reduced (p < 0.05). The tested concentration of the herbicide probably provoked disturbances in the acid-base ionic balance and it can also be considered a clastogenic and poisonous product.

Authors: Dellamatrice P. M. , Monteiro Regina T. R.
Published: July 2024

The Municipal Treatment Station of Americana, São Paulo, Brazil, manages 400 L s–1 of effluent, from domestic and textile origin, which produces an average of 20 t of sludge per day. The degradation of the effluent and sludge by cyanobacteria, by fungus Pleurotus, and anaerobic system was evaluated after an activated sludge treatment. The detoxification was appraised with three bioassays comprising the cnidarian Hydra attenuata, the algae Selenastrum capricornutum and lettuce (Lactuca sativa) seeds. All the microorganisms were able to degrade and detoxify the effluent. The strains of Pleurotus were able to decolorized the sludge, however the toxicity increased. The three strains produced high amounts of manganese-peroxidase and laccase in the presence of the effluent or sludge. The anaerobic/aerobic treatment was the most efficient for degradation of the effluent and reducing its toxicity.

Published: July 2024

The action of wastewater from Paulínia Petroleum Refinery (REPLAN) was tested in freshwater planarian regeneration, from the species Dugesia (Girardia) tigrina. This chronic toxicity test was realized to establish conditions to use them as a monitoring species of the refinery treatment efficiency. The tested samples wore collected at six points: rio Jaguari (REPLAN water intake); wastewater beginning biological treatment (after physical treatment); wastewater entering stabilization lagoon (last stage of treatment); discharge of stabilization lagoon; upstream from effluent discharge at rio Atibaia; downstream from the effluent discharge. Drinking water was used as control. Five or eight adult planarian at regeneration stage was tested in each point. The adult tested specimens were selected and weren’t feed during the experiment. The test was initiated immediately after the removal of planarian’s head (cut with blade) and finalized when the regeneration was complete. It was detected high toxic effect only at the sample from the primary treatment discharge, before realizing the aeration and biological treatment. We can conclude that REPLAN effluent, at the end of the treatment process don’t cause any effect in Dugesia (Girardia) tigrina cephalic regeneration.

Authors: Manarinjara Vazoly Fiadanampo , St Flour Pierre Olivier
Published: July 2024

This research emphasises the challenges confronting Small and Medium-sized Enterprises (SMEs) in finding ways to reconcile sustainability and innovation. There are many obstacles to overcome in African countries such as Madagascar. The methodology used in conducting this research is the review of literature and the study of Malagasy SMEs case. The result of the research show that Malagasy entrepreneurs operating in the SMEs are determined to bring innovation. However, the Malagasy SMEs are confronted with the political and economic situation of the country which are putting them in an awkward position. Moreover, the scarcity of financial resources and expertise is not in favour of sustainable innovation. Innovation and sustainability require a conducive environment for their development and implementation. The diversity of resources in Madagascar constitutes a potential that should be the leverage for economic growth, which in turn offers an opportunity for Malagasy SMEs to diversify their activities. Therefore, solving these issues that prevent innovation and sustainability is fundamental so that the Malagasy SMEs’ lifecycle can be sustained in the long-term, and contribute to the economic growth of the country.

Published: July 2024

Öğrenciler gelişen çağa ayak uydurabilmek için matematiksel modelleme bilgi ve yeterliliğine sahip olabilecek şekilde eğitim almalıdır. Onları yetiştirecek öğretmenlerin bu konuda donanım sahibi olmaları bu bakımdan çok önemlidir. Bu çalışmanın amacı ortaokulda görev yapan öğretmenlerin matematiksel modelleme etkinliklerinin kullanımı ile ilgili bilgi ve yeterliliklerinin ne durumda olduğunun ortaya koymaktır. Araştırmada dört ortaokul matematik öğretmeniyle bir durum çalışması gerçekleştirilmiştir. Öğretmenlerin matematiksel modellemeyle ilgili ön bilgileri yarı yapılandırılmış görüşme yoluyla elde edilmiştir. Öğretmenlerin matematiksel modelleme etkinlikleri ve süreci ile ilgili tam olarak bilgi sahibi olmadıkları genel olarak somutlaştırma şeklinde yorumladıkları ortaya çıkmıştır. Ayrıca öğretmenlerle yürütülen ön görüşmeden sonra öğretmenlere matematiksel modellemeyle ilgili seminer verilip öğretmenlerin derslerinde matematiksel modelleme uygulamaları gözlemlenmiştir. Eğitimlerin ve uygulamaların ardından araştırmanın sonuçlarına göre, öğretmenlerin büyük oranda matematiksel modelleme kavramını tam olarak anlamadıkları ve model oluşturma prensiplerini eksik uyguladıkları belirlenmiştir. Daha sonra öğretmenlerle son görüşme ve öğrencilerle uygulamaya dair görüşme yapılmıştır. Öğretmenlerin matematiksel modellemeyi kavradıkları ancak derslerinde matematiksel modelleme uygulamalarını kullanma açısından istekli olmadıkları sonuçları ortaya çıkmıştır. Gerekçe olarak modelleme etkinliklerinin çok zaman alması ve öğretmenlerin bu konuda yeterli donanıma sahip olmamaları gösterilmiştir. Öğrencilerinse bu etkinliklerle ilgili olumlu görüşe sahip oldukları sonucu ortaya çıkmıştır. Öğrenciler matematiksel modelleme etkinliklerini düşünmeyi geliştirici, eğlenceli ve gerekli gördüklerini ifade etmişlerdir. Sonuçlar değerlendirildiğinde, öğretmenlerin matematiksel modellemeyi daha iyi anlamaları, model oluşturma becerilerini geliştirmeleri ve matematiksel modelleme etkinliklerini etkili bir şekilde sınıflarında kullanabilmeleri için hizmet içi eğitime ihtiyaçları olduğu söylenebilir. Çalışmanın sonuçları, öğretmenlerin matematiksel modelleme ile ilgili farkındalıklarını arttırmanın yanı sıra bu yöntemi daha etkili bir şekilde kullanmalarını teşvik etmeyi amaçlayan araştırmalara katkı sağlayabilir.

Authors: Tsekhmistro L. N. , Frolov A. V. , Derekh E. K. , Yemialyantsava T. V.
Published: July 2024

Objective. To study state dynamics of the cardiovascular system of athletes in acyclic sports against the background of submaximal physical activity to identify individuals at high risk of cardiovascular complications, including sudden cardiac death

Materials and methods. The survey was conducted among athletes of acyclic sports. Number of people examined: 50, average age 20.0±3.5 years old. Of these, 30 (60%) were men, average age 19.9±3.4 years old; women – 20 (40%), average age 21.0±3.8 years old. Qualification of athletes: CMS, MS, MSIC.

Results. At rest, instability of the depolarization phase is indicated by two ECG markers: a fragmented frQRS complex and a spatial QRS-T angle of more than 105º. Fragmented frQRS was detected in 73% of young males and 33% of young females. The average values of the QRS-T angle were within the physiological norm: 63±23º in young males and 40±14º in young females. Electrical ventricular systole, expressed by the Q-T interval, was 373±26 ms in young males and 385±35 ms in young females. The average value of the second indicator of repolarization instability Q-T interval dispersion was 50.7±12.8 ms in young males and 39.3±14.6 ms in young females. The average TWA amplitude in young males was 21.0 (18; 24) μV, and 20.5 (14; 25) μV in young females. Analysis of ECG markers of dysfunction of autonomic nervous regulation showed that the slowdown in heart rate DC was 19.0 (14.8; 31.5) ms in young males, 19.5 (11.8; 21.5) ms in young females. The acceleration of heart rate AC in young males was 19.8 (13.8; 26.0) ms, and 19.5 (11.5; 21.5) ms in young females.

After the load, no statistically significant changes in the frequency of detection of fragmented frQRS were observed in young males (p = 0.7472), while in young females a statistically significant increase in the frequency of detection of frQRS was detected (p = 0.0226). The average value of the QRS-T angle increased significantly – from 63±23ºto 85±25º in young males (p = 0.0117), while it did not change significantly in young females – from 40±24º to 55±26º  (p = 0.2606). Q-T dispersion in afterload compared to rest increased from 50.7±12.8 ms and reached 72.8±25.0 ms (p = 0.000) in young males and from 39.3±14.6 ms to 68.2 ±10.7 ms in young females (p = 0.0029). Deceleration (DC) and acceleration (AC) of heart rate decreased significantly in young males. For young males – by 77.7 and 82.3%, respectively (p < 0.0001), and for young females – by 84.9 and 80.0%, respectively (p < 0.0001).

Conclusion. At rest, we identified only 10 markers of electrical instability of the myocardium, and 38 markers after exercise, that is, almost 4 times more. This suggests that even in highly qualified athletes, load causes a trend towards electrical instability of the myocardium, mainly in the repolarization phase and in relation to autonomic nervous regulation.

Published: July 2024

Objective. To identify the relationships between the levels of microRNA and mRNA during pathological angiogenesis under the conditions of experimental toxic liver cirrhosis.

Materials and methods. Fibrosis and liver cirrhosis were induced in male Wistar rats using a freshly prepared solution of thioacetamide over 17 weeks. The dynamics of the process were studied at 9 time points. The areas of interlobular veins and interlobular arteries were measured in micrometers. The numbers of interlobular arteries, interlobular veins, and sinusoidal capillaries were counted. The expression levels of mRNA genes Ang, Vegfa, Tweak, Fn14, Notch1, Notch2, and microRNAs-195-5p, microRNAs-664-3p, microRNAs-489-3p, microRNAs-3085, microRNAs-3558-3p in the liver were determined by real-time polymerase chain reaction.

Results. It was found that during progressive venous angiogenesis, as well as against the background of changes in the number of interlobular veins, sinusoidal capillaries, and the area of interlobular veins, the nature and strength of correlational interactions between the genes Ang, Vegfa, Tweak, Fn14, Notch1, Notch2, and microRNAs-195-5p, microRNAs-664-3p, microRNAs-489-3p, microRNAs-3085, microRNAs-3558-3p are associated with the stage of fibrosis and liver cirrhosis. Strong, moderate, and mild correlational links (p<0.01) were identified between the genes Ang, Vegfa, Tweak, Fn14, Notch1, Notch2 throughout the experiment.

Conclusion. The obtained results indicate that the studied microRNAs - microRNAs-195-5p, microRNAs-664-3p, microRNAs-489-3p, microRNAs-3085, microRNAs-3558-3p - are involved in the processes of restructuring the intrahepatic vascular bed at different stages of experimental toxic fibrosis and liver cirrhosis. The results of the study not only reveal additional mechanisms of formation of the indicated conditions but also identify the biological role of the studied microRNAs in the progression of fibrosis and liver cirrhosis as potential targets for studying pathogenesis and developing treatment methods.
Miroslav Válek: Three Stages of Canonicity
Authors: Nádaskay Viliam
Published: July 2024

The article focuses on the seminal Slovak poet Miroslav Válek (1927–1991) and his place in the Slovak literary canon. It reconstructs Válek’s literary trajectory, from being a poet of individualist and intimate verse who entered Slovak literature during the political thaw and liberalisation, as an important voice of the generation, to a poet who inclined towards long associative poems with political overtones, culminating in his controversial book-length poem in the 1970s, during his no less controversial time as minister of culture of the Slovak Socialist Republic. Based on the critical reception and publishing history of Válek’s poetry, the paper pays attention to shifts and ambiguities in the poet’s position in both the socialist and post-socialist literary canons. Despite certain fluctuations, the basis of his image remains the same, rooted in his own poetic programme, which coincided with the preferred image of a poet’s work at the time: Válek was and remains both a poet and a politician, a poet of inner turmoil, and a poet of social and political being. The difference the paper attempts to describe is that the socialist literary canon did not differentiate between these extremes (at least in official literary criticism), whereas the Slovak post-socialist canon, which is generally sceptical towards political tones in art, makes the distinction clearly.

Teaching food analysis through unknowns: Study case for methylxanthines, organic acids, and sugars examination over liquid chromatography
Authors: Granados-Chinchilla Fabio
Published: July 2024

Three laboratory sessions are described, each one focused on a distinct group of analytes (i.e., 1. Methylxanthines, 2. Organic acids 3. Sugars). To study each analyte group, food profiling was achieved using liquid chromatography; where each analyte (n = 3, 15, and 5 analytes for methylxanthines, organic acids, and sugars, respectively) was identified and quantified. Different food samples (including beverages, powders, cereals, and dairy products) were given to students who within each class knew the possible identities of the group of samples given but had to pair, after examination, the resulting profiles obtained with each food sample as the food samples were unidentified (unknowns). Quali/Quantitative data were recollected from the resulting chromatograms after each food was subjected to analysis. For organic acids, solid phase extraction and potentiometry were used as tools to demonstrate separation science from colored drinks as sample pretreatment and as a classic alternative for instrumental analysis.
Investigating high school students’ ideas about energy transfer in simple electric circuits
Authors: Winter Louisa Christine , Pilser Anna
Published: July 2024

In a recent study, nine students, aged 16-17 years, from Vienna, Austria have been interviewed about energy in electrical circuits. This paper reflects on one part of the study focusing on questioning students about the process of energy transfer. The research design and method involved semi-structured interviews with demonstration experiments, in which the students were asked to observe, describe and explain the experiments. The analysis of the interviews revealed the difficulties students faced in explaining the role of energy and drawing the path of energy transfer in electrical circuits. The paper presents the different energy frameworks described by previous studies that have been used by the students and discusses the inconsistencies in their reasonings. The findings emphasize the need for suitable teaching materials to promote students’ understanding about energy and energy transfer in electrical circuits.

Abstract. Tropopause-overshooting convection in the midlatitudes provides a rapid transport pathway for air from the lower troposphere to reach the upper troposphere and lower stratosphere (UTLS) and can result in the formation of above-anvil cirrus plumes (AACPs) that significantly hydrate the stratosphere. Such UTLS composition changes alter the radiation budget and impact climate. Novel in situ observations from the NASA Dynamics and Chemistry of the Summer Stratosphere (DCOTSS) field campaign are used in this study to examine UTLS impacts from AACP-generating overshooting convection. Namely, a research flight on 31 May 2022 sampled active convection over the state of Oklahoma for more than 3 h with the NASA ER-2 high-altitude research aircraft. An AACP was bisected during this flight, providing the first such extensive in situ sampling of this phenomenon. The convective observations reveal pronounced changes in air mass composition and stratospheric hydration up to altitudes of 2.3 km above the tropopause and concentrations more than double background levels. Unique dynamic and trace gas signatures were found within the AACP, including enhanced vertical mixing near the AACP edge and a positive correlation between water vapor and ozone. Moreover, the water vapor enhancement within the AACP was found to be limited to the saturation mixing ratio of the low temperature overshoot and AACP air. Comparison with all remaining DCOTSS flights demonstrates that the 31 May 2022 flight had some of the largest tropospheric tracer and water vapor perturbations in the stratosphere and within the AACP.

Abstract. Within the TURBAN project, a "Legerova campaign" focusing on air quality and meteorology in the traffic-loaded part of the Prague city (Czech Republic) was carried out from 30 May 2022 to 28 March 2023. The network comprised of 20 combined low-cost sensor (LCS) stations for NO2, O3, PM10 and PM2.5 concentrations, along with a mobile meteorological mast, a single-channel microwave radiometer and Doppler LIDAR for measurement of vertical temperature and wind profiles. Significant individual deviations of LCSs were detected during the 165 day initial field test of all units at the urban background Prague 4-Libuš reference station (coefficient of variation 17–28 %). Implementing the Multivariate Adaptive Regression Splines method for correction reduced the LCS inter-individual variability and improved correlation with reference monitors in all pollutants (R2 0.88–0.97). The LCSs' data drifts and ageing were checked by the double mass curve method for the entire measurement period. During the Legerova campaign, the highest NO2 concentrations were in traffic-loaded street canyons with continuous building blocks and several traffic lights. Aerosol pollution showed very little variation between the monitored streets. The highest PM10 and PM2.5 concentrations were recorded during temperature inversions and an episode involving pollution transported from a large forest fire in northern Czech Republic in July 2022. This report provides valuable data to support the validation of various predictive models dealing with complex urban environment, such as microscale LES model PALM tested in the TURBAN project.

Abstract. The Amundsen Sea region in Antarctica is a critical area for understanding future sea level rise due to its rapidly changing ice dynamics and significant contributions to global ice mass loss. Projections of sea level rise from this region are essential for anticipating the impacts on coastal communities and for developing adaptive strategies in response to climate change. Despite this region being the focus of intensive research over recent years, dynamic ice loss from West Antarctica and in particular the glaciers of the Amundsen Sea represent a major source of uncertainty for global sea level rise projections. In this study, we use ice sheet model simulations to make sea level rise projections to the year 2100 and quantify the associated uncertainty. The model is forced by climate and ocean model simulations for the RCP8.5 and Paris2C scenarios, and is carefully calibrated using measurements from the observational period. We find very similar sea level rise contributions of 19.0 ± 2.2 mm and 18.9 ± 2.7 mm by 2100 for Paris2C and RCP8.5 scenarios, respectively. A subset of these simulations, extended to 2250, show an increase in the rate of sea level rise contribution and clearer differences between the two scenarios emerge as a result of differences in snow accumulation. Our model simulations include both a cliff-height and hydrofracture driven calving processes and yet we find no evidence of the onset of rapid retreat that might be indicative of a tipping point in any simulations within our modelled timeframe.
Quantifying the Impacts of Marine Aerosols over the Southeast Atlantic Ocean using a chemical transport model: Implications for aerosol-cloud interactions
Authors: Hossain Mashiat , Garland Rebecca M. , Horowitz Hannah M.
Published: July 2024

Abstract. The southeast Atlantic region, characterized by persistent stratocumulus clouds, has one of the highest uncertainties in aerosol radiative forcing and significant variability across climate models. In this study, we analyze the seasonally varying role of marine aerosol sources and identify key uncertainties in aerosol composition at cloud-relevant altitudes over the southeast Atlantic using the GEOS-Chem chemical transport model. We evaluate simulated aerosol optical depth (AOD) and speciated aerosol concentrations against those collected from ground observations and aircraft campaigns such as LASIC, ORACLES, and CLARIFY, conducted during 2017. The model consistently underestimates AOD relative to AERONET, particularly at remote locations like Ascension Island. However, when compared with aerosol mass concentrations from aircraft campaigns during the biomass burning period, it performs adequately at cloud-relevant altitudes, with a normalized mean bias (NMB) between −3.5 % (CLARIFY) and −7.5 % (ORACLES). At these altitudes, organic aerosols (63 %) dominate during the biomass burning period, while sulfate (41 %) prevails during austral summer, when dimethylsulfide (DMS) emissions peak in the model. Our findings indicate that marine sulfate can account for up to 69 % of total sulfate during high DMS period. Sensitivity analyses indicate that refining DMS emissions and oxidation chemistry may increase sulfate aerosol produced from marine sources, highlighting their overall importance. Additionally, we find marine primary organic aerosol emissions may substantially increase total organic aerosol concentrations, particularly during austral summer. This study underscores the imperative need to refine marine emissions and their chemical transformations to better predict aerosol-cloud interactions and reduce uncertainties in aerosol radiative forcing over the southeast Atlantic.
