Energieträger Wasserstoff – womit Feuerwehren rechnen müssen
Authors: Konersmann Rainer
Published: June 2024

Der Gefahrguttransport mit Eisenbahnkesselwagen, Pipelines und Tankschiffen verläuft in der Regel unproblematisch und fast unter Ausschluss der Öffentlichkeit. Er taucht nur dann in den Schlagzeilen auf, wenn etwas schief gegangen ist und nicht zu übersehende Schäden entstanden sind. Ölverseuchte Küsten oder ausgebrannte Kesselwagen zum Beispiel. Beim Transport von Energieträgern über öffentliche Verkehrswege ist es ähnlich. An den Anblick von Tankwagen, gefüllt mit Kraftstoffen, Heizöl und Flüssiggas haben wir uns gewöhnt. Die vielen Tankstellen und Kunden müssen ja irgendwie beliefert werden. Aber nun wird bald in zunehmendem Maße im dichten Verkehrsgetümmel der neue Energieträger Wasserstoff auftauchen. Was passiert eigentlich, wenn ein Wasserstofftransporter in einen Unfall verwickelt wird? Auf welche Szenarien müssen sich die Feuerwehren einstellen?

Multisensory processing impacts memory for objects and their sources

Published: June 2024

Multisensory object processing improves recognition memory for individual objects, but its impact on memory for neighboring visual objects and scene context remains largely unknown. It is therefore unclear how multisensory processing impacts episodic memory for information outside of the object itself. We conducted three experiments to test the prediction that the presence of audiovisual objects at encoding would improve memory for nearby visual objects, and improve memory for the environmental context in which they occurred. In Experiments 1a and 1b, participants viewed audiovisual–visual object pairs or visual–visual object pairs with a control sound during encoding and were subsequently tested on their memory for each object individually. In Experiment 2, objects were paired with semantically congruent or meaningless control sounds and appeared within four different scene environments. Memory for the environment was tested. Results from Experiments 1a and 1b showed that encoding a congruent audiovisual object did not significantly benefit memory for neighboring visual objects, but Experiment 2 showed that encoding a congruent audiovisual object did improve memory for the environments in which those objects were encoded. These findings suggest that multisensory processing can influence memory beyond the objects themselves and that it has a unique role in episodic memory formation. This is particularly important for understanding how memories and associations are formed in real-world situations, in which objects and their surroundings are often multimodal.

Background and objectives. The endodontic treatment of primary teeth presents significant challenges due to their unique anatomical characteristics. To ensure a successful treatment, it is essential to evaluate a few factors. These factors include accurate diagnosis, disinfection protocol, intracanal medicaments, and irrigation solutions. While Sodium hypochlorite (NaOCl) has gained success as an irrigation agent in primary teeth, it is important to note that higher concentrations of NaOCl can potentially cause toxicity to the periapical environment if they pass through the tooth's apical foramina. Thus, this study compared the cytotoxicity of two different concentrations of sodium hypochlorite at varied volumes on red blood cells (RBC). Materials and methods. In order to evaluate the cytotoxicity potential, fresh human blood was collected from a single healthy individual and subjected to testing. For the test, 10 µL, 20 µL, 30 µL, 40 µL and 50 µL of 1% and 3% NaOCl were added to the RBC. The tubes were gently mixed and incubated at 37°C for 30 minutes. A UV-visible spectrophotometer was used to calculate the absorbance of the supernatant at a wavelength of 540 nm. Results. There was no significant difference in 1% sodium hypochlorite at different volumes with a p value >0.05 using Tukey's post hoc test. However, there was a significant difference between the volumes of 3% sodium hypochlorite at 40 and 50 µg/ml with a p value of 0.004 and 0.001 respectively. Conclusions. According to the current study's findings, 1% sodium hypochlorite solution exhibited less toxicity than 3% sodium hypochlorite.

Synergizing Unsupervised and Supervised Learning: A Hybrid Approach for Accurate Natural Language Task Modeling
Authors: Talukdar Wrick , Biswas Anjanava
Published: June 2024

While supervised learning models have shown remarkable performance in various natural language processing (NLP) tasks, their success heavily relies on the availability of large-scale labeled datasets, which can be costly and time-consuming to obtain. Conversely, unsupervised learning techniques can leverage abundant unlabeled text data to learn rich representations, but they do not directly optimize for specific NLP tasks. This paper presents a novel hybrid approach that synergizes unsupervised and supervised learning to improve the accuracy of NLP task modeling. While supervised models excel at specific tasks, they rely on large labeled datasets. Unsupervised techniques can learn rich representations from abundant unlabeled text but don't directly optimize for tasks. Our methodology integrates an unsupervised module that learns representations from unlabeled corpora (e.g., language models, word embeddings) and a supervised module that leverages these representations to enhance task-specific models [4]. We evaluate our approach on text classification and named entity recognition (NER), demonstrating consistent performance gains over supervised baselines. For text classification, contextual word embeddings from a language model pretrain a recurrent or transformer-based classifier. For NER, word embeddings initialize a BiLSTM sequence labeler. By synergizing techniques, our hybrid approach achieves SOTA results on benchmark datasets, paving the way for more data-efficient and robust NLP systems.

Authors: Grinberga-Zalite Gunta , Zvirbule Andra , Hernik Joanna
Published: June 2024

This research aims to explore the acceptance of unconventional food products that convey creative solutions for sustainable food production and consumption. This paper presents the first stage results of an extensive Baltic Sea region’s population survey organized to understand how innovative food products’ creators could better enhance the link between sustainable products and different segments’ customer acceptance. In scope of this study, the authors focused on youth market segments, who are known for their adventurous and experimental eating habits. The authors hypothesized that products that have been created to comply with socially responsible and sustainable food products’ requirements face resistance from the youth who do not view them as superior to conventional ones. The cross-sectional study utilized mixed-method methodology, combining qualitative and quantitative approaches, including a literature review, in-depth focus group interviews, and comparative analysis using normal distribution assessment and sentiment classification. The research findings indicate that while the youth acknowledge the social and environmental benefits of innovative food products, they remain hesitant to adopt them personally. Therefore, it is vital for innovative food creators to understand the biases and behaviors of young consumers, ensuring transparency about product contents, motivating them to embrace new consumption models, try unconventional foods, and highlight the personal and societal advantages of purchasing these items.

Lithuania’s total road network consists of more than 84000 km of roads, of which more than 21000 km are national roads. Roads of national importance are managed by the Lithuanian Road Administration. The remaining roads are classified as local roads managed by local governments. Road installation and maintenance often lead to the problem of surface water drainage and accumulation on the road surface. The aim of this study is to identify and propose the most appropriate permeable asphalt pavement construction to solve this problem, taking into account the purpose of the application and the class of pavement structure. The scope of the study identifies three recommended permeable asphalt pavement designs for the installation of DK 0.1-DK 1 pavement structures in ancillary streets, parking and recreation areas where light vehicle traffic with occasional heavy vehicle traffic. It has also been found that in areas of high traffic intensity, it is appropriate to use an alternative to permeable pavements – a permeable pavement design for the shoulder, where the roadway structure is impermeable to water and the shoulders are permeable to water (a permeable pavement structure is installed). The recommended permeable asphalt pavement structures, when properly selected, reduce the risk of flooding on the roadway.

Heavy tillage practices to conserve moisture from monsoon rains are common in rainfed regions. Rainfed regions have wheat (Triticum aestivum) as a main crop while rest of the year minor crops are grown such as lentil. Heavy tillage practices not only destroyed the soil structure but also caused loss of carbon. This study was designed to investigate impact of different tillage practices on yield of lentil (Lens culinaris) and carbon dynamics. Three tillage practices were considered as: T1 = 6 cultivations (Control), T2 = moldboard plough + 2 cultivations, T3 = chisel plough + 2 cultivations. The experiment was conducted using a randomized complete block design with three replications to investigate the impact of tillage practices on carbon dioxide (CO2) emission, soil organic carbon (SOC), dissolved organic carbon (DOC), and the yield of lentil crop. Results indicated that during both the years (2018–2019), moldboard plough with 2 cultivations (T2) reduced CO2 emission (40.28%), DOC (22.58%) and SOC (51.07%) and increased lentil yield (56.39%) as compared to control. Results of soil carbon monitoring indicated that use of moldboard and chisel plough along with 2 cultivations before the onset of monsoon under rainfed conditions can reduce CO2 emission and improve the yield compared to conventional tillage practices. Results of the experiment suggest the farmers of the rainfed area that they should use moldboard and chisel plough along with 2 cultivations before the onset of monsoon so that CO2 emission can be minimized, and they can get more better yield compared to conventional tillage practices which causes loss of CO2 and nutrients.

Theobroma cacao L., cocoa, produces fruits throughout the year with one or two peaks. The relationship between pod or bean characteristics and leaf nutrient status in cocoa genotypes grown in the humid tropics of India is not well documented. Our investigation found notable differences amongst twenty genotypes of cocoa for pod weight, husk weight, bean count, fresh bean weight pod, single dry bean weight, nib recovery, and shell percentage. Single dry bean weight is an important parameter of the cocoa beans for the industry, and it was significantly associated with the husk weight, pod weight, and nib recovery. The weight of the dry bean was found to be higher in pods with higher pod weight and husk weight. However, it decreased significantly with increased bean count per pod. Higher nib recovery is another important industry trait and was closely associated with single dry bean weight. Pearson’s correlation coefficients indicated pod and bean characteristics in different genotypes had no significant association with leaf nutrient status. Even, the nutrient ratios had no tangible influence on the pod/bean traits, except for K/P and Ca/B, which had significant associations with the husk weight and pod count per tree, respectively.
Adaptive patterns of anti-predator escape behavior in a globally introduced bird species

Introduced species can represent quasi-experimental, anthropogenic case studies of both ecological and evolutionary principles. When these species are firmly established, competitive interactions between native and introduced species interactions, including foraging, spacing, and breeding competition, may be among the ecological costs incurred from such species invasions. In turn, genetic and/or plasticity-driven changes in behavior and morphology could also take place in the invading species with increasing introduction lag (time since the onset of introduction). Critically, however, introduction lag is difficult to study in any single non-native population without long-term observations, and, instead, it requires geographically repeated measures of the focal response variables across invasive populations that were introduced at different times. Here we tested a priori predictors of predator-avoidance behaviors through the flight initiation distance (FID) assay of a widely distributed invasive bird species, the common myna Acridotheres tristis. The species was extensively and consistently sampled throughout most of its independently introduced ranges across all hemispheres. Critically, FID increased with greater introduction lag. We also detected additional functional patterns in that FID increased towards the rural range within a continuous metric of urban-rural gradient and also at shorter distances from the Equator. Any robust study of FID must also include proximate predictors as well and, accordingly, we found that FID increased with greater starting distance, with lower immediate human density, with flighted over walking escape responses, and at lower heights of a bird’s perch above ground but was unrelated to myna group size. Respectively, these factors are informative about the sensory cues triggering anti-predator behaviors in invasive mynas and imply an adaptive set of patterns of anti-predator responses in the introduced ranges of this species. Control measures of invasive common myna populations should take into account their extensive behavioral and cognitive flexibilities and adjust the planned management methods accordingly.

Hepatitis B virus (HBV) reactivation associated with various therapeutic interventions is a significant cause of morbidity and mortality among patients with current or resolved HBV infection. Since no curative treatment for HBV infection is currently available, a large number of individuals in the general population are at risk for HBV reactivation. Populations vulnerable to HBV reactivation include those currently infected with HBV or those who have had past exposure to the virus. The potential consequences of HBV reactivation are particularly concerning when these populations undergo anti-cancer chemotherapy, immunosuppressive or immunomodulatory therapies for managing various malignancies, rheumatologic diseases, inflammatory bowel disease, or undergo solid-organ or hematologic stem cell transplantation. This article aims to increase awareness of HBV reactivation and to elucidate the mechanisms and risks associated with HBV reactivation in various clinical settings.
