Spatial and temporal dynamics of seedborne, airborne, and foliar fungal communities in Swedish forest nurseries
Authors: Larsson Rebecca
Published: April 2024

Fungal infections in forest nurseries can significantly affect the economic sustainability of tree seedling production. Increased knowledge of local fungal communities, especially prevalent pathogens, could improve preventative and targeted control strategies, ultimately reducing the usage of fungicides. This thesis aimed to acquire new knowledge and advance a general understanding of seedborne, airborne, and foliar fungal communities in Swedish forest nurseries. The studies were conducted in five forest nurseries. Fungal communities were assessed from Picea abies, Pinus sylvestris, and Larix sp. seeds differentiated between the surface and the tissue (paper I), non-symptomatic P. sylvestris needles (paper II), and deposited spores (paper IV) using high-throughput sequencing of the ITS2 rDNA region. Results showed that seedborne fungal communities were distinguished between the seed surface and the seed tissue, where fungi from the seed surface showed a strong host-affinity and regional dependence. This result suggests that the movement of seeds between different geographic regions, including frequently traded seeds, could be a potential source of the spread and introduction of fungal species. The foliar and airborne fungal communities comprised high species richness and showed clear temporal shifts over the seedling growing seasons. The experiments included microbial treatments to control fungal pathogens and stimulate seedling growth on P. sylvestris seedlings. However, the use of microbial treatments was not found to impact the seedling growth or the disease incidence, which was generally low, and had no impact on the foliar fungal communities. All the fungal communities showed a high prevalence of nursery fungal pathogens, e.g., Cladosporium sp., Botrytis cinerea, Phoma herbarum, and Sydowia polyspora. In this thesis, the disease incidence of Diplodia sapinea in P. sylvestris seedlings was confirmed (paper III). Additionally, low abundances of D. sapinea were detected from the seeds and the deposited airborne spores. The findings in this thesis may contribute to developing disease management strategies in forest nurseries owing to a better understanding of fungal communities, thereby highlighting the importance of managing fungal pathogens to maintain healthy tree seedling production.
Becoming Connected - Adolescent Social-Cognitive Development in the Peer Context
Authors:   , Hollarek Miriam
Published: April 2024

The development of social-cognitive abilities during adolescence is vital for the formation of positive lasting social relationships outside the family. A better understanding of the development of adolescent social-cognitive abilities can potentially foster positive social relationships, heighten resilience, and improve general well-being and mental health for adolescents. Research in the past decade has provided strong evidence that social-cognitive abilities and their underlying neural functions are still under development during adolescence. However, the specific developmental trajectories of distinct social-cognitive abilities, and individual differences relating to their development have not yet been established. The aim of the current dissertation was to further our understanding of the development of specific social-cognitive abilities during adolescents and how they shape and are shaped by the peer environment. Overall, the present dissertation confirms that adolescence is a period of continued social-cognitive development. The precise developmental trajectories depend on the specific social-cognitive process and show individual differences, depending on factors such as the peer environment and gender. Our results demonstrate a bidirectional interaction in which social-cognitive abilities shape and are shaped by the peer context during adolescence. As such, the present dissertation confirms that the combination of adolescents’ social reorientation and continued maturation of the neural networks of the social brain present unique opportunities for adolescents’ social-cognitive development and highlights the role of the peer context in influencing positive or negative developmental trajectories.

Published: April 2024

A brucelose em bubalinos e bovinos é reconhecida como doença infecto-contagiosa causada pela Brucella abortus (B. abortus), caracterizada por manifestações clínicas da esfera reprodutiva e severos prejuízos aos produtores. As investigações sorológicas voltadas à brucelose bubalina no Brasil praticamente estão restritas à comparação de animais reagentes frente às diferentes técnicas diagnósticas. Com efeito, são escassos os estudos no país conduzidos no acompanhamento sorológico de bezerras bubalinas vacinadas, conforme as recomendações do PNCEBT, particularmente no que tange ao uso das provas confirmatórias do 2-mercaptoetanol e fixação de complemento. O presente estudo avaliou o perfil sorológico anti-Brucella abortus em bezerras bubalinas, vacinadas entre 3 a 8 meses com a B19, utilizando o teste do antígeno acidificado tamponado recomendado pelo PNCEBT, com vistas a contribuir para o diagnóstico e controle da brucelose em bubalinos no Brasil. Na prova do AAT, aos 15 dias pós-vacinais, 20 (95,2%) das 21 fêmeas bubalinas vacinados entre 3 a 8 meses com a vacina B19 apresentaram-se reagentes. Nesta prova um (4,8%) animal mostrou-se reagente somente no 60o dia pós-vacinal. Entre o 60o e 120o dias pós-vacinais todos os animais foram reagentes. Aos 150 dias de acompanhamento, dois (9,5%) animais não se apresentaram reagentes. Entre o 180o e 240o dias pós-vacinais foi observado declínio acentuado do número de animais reagentes. No 270o dia pós-vacinal, somente um (4,8%) animal mostrou-se reagente e, aos 300 dias de acompanhamento, nenhum animal foi encontrado reagente na prova de AAT, permanecendo não reagentes até os 720 dias de acompanhamento. Cabe aos profissionais do agronegócio a correta informação aos proprietários e criadores para que animais vacinados não sejam considerados reagentes quando testados fora do tempo preconizado.

Published: April 2024

Este artigo avalia os determinantes individuais e regionais do deslocamento pendular por motivo de trabalho nos municípios do estado do Ceará. No que tange aos aspectos metodológicos, empregou-se o modelo logit hierárquico espacial. Os dados utilizados são provenientes do Censo 2010, do IBGE, da FIRJAN, do DENATRAN, do DATASUS e do IPEADATA. Os resultados a nível individual indicam que os trabalhadores que têm maiores chances de realização do deslocamento pendular são: do sexo masculino; brancos; mais velhos; com maior nível educacional; e que residem em área urbana. A nível municipal, as evidências mostram que quanto maior nível de emprego e renda do setor formal e o coeficiente de Gini dos municípios menores são as chances de deslocamento diário para trabalho. A probabilidade de pendular aumenta com o maior acesso ao transporte público, além de maior nível de emprego e renda no setor formal e maior grau de urbanização nos municípios vizinhos.

Una etnografía interescalar sobre políticas de la primera infancia
Authors: Paz Landeira Florencia
Published: April 2024

En este artículo, presento reflexiones metodológicas emergentes de mi investigación doctoral sobre políticas para la primera infancia en Argentina. A partir de identificar la creciente centralidad de la primera infancia como un eje de la protección social, indago en cómo abordar discursos institucionales y expertos que moldean los contornos de una agenda pública, cristalizando evidencias y buenas prácticas para la gestión de políticas y, de fondo, sedimentando y legitimando nociones acerca de lo infantil, su cuidado y sus necesidades. A los fines de abordar los caminos y las prácticas a través de los que se producen, circulan y se reencuadran los discursos que subyacen a las políticas, opté por lo que denomino una etnografíainterescalar. En esta opción metodológica, el Plan Nacional de Primera Infancia funcionó como un prisma complejo de indagación y como organizador de la estrategia narrativa, cuyo análisis requirió un abordaje desde distintas escalas contextuales.
PR-316-21201-R02 Dry Gas Seal Reliability - The Effects of Liquid Contamination on Seal Performance
Authors: Anguiano Mark , Rimpel Aaron
Published: April 2024

This project continues research to enhance dry gas seal (DGS) reliability. Previous work reviewed failures from the literature and experience of manufacturers and end users and identified that liquid contamination was the most common cause, but it was concluded that there was insufficient quantitative data to base recommendations on for further DGS reliability enhancements. Therefore, experimental and analytical investigations were pursued to fill the void. The ultimate objective was to be able to predict DGS failures due to liquid contamination, which could lead to greater DGS reliability through improvements in design, instrumentation, and monitoring.

Published: April 2024

This paper delves into the critical exploration of hydrogen supply chains downstream (HSCD) in the Western U.S., responding to the nation’s prioritization of hydrogen as a clean alternative and its ambitious Hydrogen Program Plan for net-zero emissions and enhanced exports. We develop a conceptual model which is utilized to identify gaps in the existing 116 regional and global review papers published from March 2020, the beginning of the COVID-19 pandemic, to November 2023. This leads us to HSCD segments, decision levels, research properties, and sustainability as the necessary criteria to analyze 48 peer-reviewed original journal papers published about HSCD in the Western U.S. until November 2023. Accordingly, we offer future research directions and contribute to the development of effective strategies for a sustainable hydrogen-based future.

The Belgian Mediators’ Code of Conduct needs to be urgently reviewed

On 16 December 2022, the Belgian Federal Mediation Commission issued the new Code of Conduct for Accredited Mediators. This code violates Belgian statute law and must therefore not be applied by Belgian judges. The Code more specifically prohibits Belgian accredited mediators to apply evaluative mediation techniques and to apply other fees schemes than those based on an hourly rate. These prohibitions violate European and Belgian mediation law as well as European and Belgian competition law.

The main objective of this research is to know the healthy lifestyle habits of people who participated in federated competitions in volleyball in the province of Jaén once their competitive stage has ended. Therefore, to investigate whether people who in their adolescence and youth practiced a federated competitive sport in volleyball, maintain healthy lifestyle habits, referring to diet, quality of sleep, level of physical activity practice and their physical condition, in their stage of adulthood and seniority. This research has been carried out though a descriptive, cross-sectional, single measurement (Ato et al., 2013), and interpretive research; in which former athletes responded to a questionnaire about their daily habits related to health; In addition, to know the information through self-completed surveys by those who were captains and technicians of the volleyball clubs, in order to better understand their current healthy habits. The total number of subjects studied was 199 people, of which 18 were captains and 21 were coaches. When asking people about their eating habits, the majority values correspond to the response option “good”, both in women (61.5%) and in men (48.8%). The different groups of participants in the research state that they attach great importance to eating habits, nutrition, and diet quality in their daily lives. 84.6% of women and 91.9% of men consider that their current level of physical fitness is based on the sports practice of their youth. Physical-sports practice as a healthy lifestyle habit is incorporated as a healthy lifestyle habit mostly in the former athletes and sports technicians participating in this research.
Association between heart rate variability and cardiorespiratory fitness in individuals with type 2 diabetes mellitus
Authors: Zaki Saima , Alam Farhan , Faizan Mohammad , Sharma Saurabh , Naqvi Irshad Husain
Published: April 2024

Background: Type 2 Diabetes Mellitus (T2DM) is associated with cardiovascular risk, which is partly due to autonomic dysfunction and decreased cardiorespiratory fitness. This study examines the relationship between heart rate variability (HRV) and maximal oxygen uptake (VO2max) in T2DM patients to understand their interconnected impacts on autonomic and aerobic functions. Methods: In a cross-sectional study, 77 T2DM patients underwent HRV and VO2max assessments using standard protocols. HRV metrics were analysed in conjunction with VO2max, measured through direct breath-by-breath analysis. Pearson's correlation coefficient was used to investigate the relationships between HRV indices and VO2max. Results: VO2max showed strong positive correlations with RMSSD (r = 0.89, p < .001), HF (r = 0.54, p < .001), and pNN50% (r = 0.52, p < .001), indicating higher parasympathetic activity with improved cardiorespiratory fitness. Negative correlations with LF (r = -0.60, p < .001) and the LF/HF ratio (r = -0.39, p < .001) suggested that better fitness levels lead to sympathetic withdrawal and a more favourable autonomic balance. Moderate positive correlations with SDNN (r = 0.46, p < .001) and TP (r = 0.58, p < .001) further suggested that overall autonomic modulation is enhanced with increased cardiorespiratory fitness. Conclusion: This study substantiates a significant correlation between HRV and VO2max in individuals with T2DM, highlighting the intricate relationship between autonomic function and aerobic capacity. These findings suggest that enhancing cardiorespiratory fitness may improve autonomic balance, offering potential avenues for mitigating cardiovascular risk in the T2DM population.
Was the 2022 FIFA World Cup in Qatar a bad omen for the future of football?
Authors: Griszbacher Norbert
Published: April 2024

Over time, football (soccer) has surpassed its core functions to become a pivotal element within the entertainment industry: billions tune in to watch mega-events such as the Champions League, European Championship, or the World Cup, and even individuals who aren’t avid fans experience certain facets of this phenomenon. As games are strongly commercialized today, organizations persistently strive to innovate the sport (e.g., introducing VAR or 10-15 minutes extra time), the number of games per season increases, and mega-events venture into unfamiliar territories, exemplified by the recent winter World Cup in Qatar. This study compares data from the last two World Cup seasons to address a fundamental question: How did the unconventional Qatar tournament affect the 2022/23 football season? Analysis revealed that while the 2022 World Cup produced impressive statistics, the club season witnessed a decrease in goals and assists (GA) compared to 2018, indicating potential challenges with the transition to the Qatari conditions. Factors such as playing position, national team federation, club league tier, and league position were identified as significant contributors to these transitional challenges. These findings gain added importance with Saudi Arabia hosting the 2034 World Cup, underscoring the need for more research to grasp the challenges ahead.

Published: April 2024

The aim of this study was to compare internal load and external load between AirBadminton and traditional indoor badminton. The research was conducted with 8 badminton players from the Alicante Technification Centre, including both men and women. The study was carried out based on the recommendations and guidelines of the International Badminton Federation. The procedure included competitions in both 1vs1 and 2vs2 formats, first on sand and then on hard court. Various variables related to players' internal and external load were analysed, using devices such as WIMU PRO for external load and Polar H7 transmitters for internal load. Data analysis was performed using statistical tests such as T-Student and Wilcoxon. Results showed significant differences between indoor badminton and AirBadminton in terms of internal and external load. In the 1vs1 format, indoor badminton was found to be more demanding, with higher intensity efforts, greater distance covered, and higher heart rate compared to AirBadminton. Similar results were observed in the 2vs2 format, confirming that indoor badminton involves greater effort. AirBadminton may be a healthier and more accessible alternative, suitable for different age groups, as it is less explosive and lighter in terms of internal and external load. Future research should focus on technical, tactical, and full-match duration aspects of this new modality.

Published: April 2024

The study aimed to compare the impact of warm-up with dynamic stretching (DS), warm-up with foam roller (FR), and warm-up with a combination of FR and DS (CO) on the performance of movement indicators in tests conducted on young volleyball players (n = 8, age = 15.4 ± 0.5 years, height = 176.3 ± 8.6 cm, weight = 64.5 ± 10.9 kg) during the competition year 2021/2022. To assess the effects of warm-up methods (DS, FR, CO), performance in various movement tests was compared. The tests included the sit and reach test (SR), a 1 kg ball throw in a kneeling position (H1), squat jump (SJ), countermovement jump (CMJ), sit-up test (SU), E-Test (ET), and run to cones (RC). The One-way ANOVA analysis did not reveal significant differences in the effects of DS, FR, and CO warm-ups (p > .05) across all investigated indicators. The effect size coefficient (η2) indicated negligible differences (η2 < 0.01), except for the ET indicator, where a small effect size (η2 = 0.028, 95%CI: 0.04-0.31) favoured DS. These findings carry social importance as they contribute to enhancing the efficacy of warm-up routines, both in sports performance and health considerations.
Modification of the relative age effect on 4-6-year-old schoolchildren’s motor competence after an intervention with balance bike
Authors: Navarro-Patón Rubén , Canosa-Pasantes Fabián , Mecías-Calvo Marcos , Arufe-Giráldez Víctor
Published: April 2024

The aims of this study were to explore: 1) the relative age effect (RAE) on aiming and catching (A&C), balance (Bal) and manual dexterity (MD) skills in 4-6-year-old schoolchildren; 2) the effect of the balance bikes program intervention; 3) the effect of this program based on gender. The Movement Assessment Battery for Children-2 (MABC-2) was administered to 50 schoolchildren [26 boys (52%) and 24 girls (48%)], aged between 4 and 5 years (M = 4.46 ; SD = 0.503), from an educational centre in Galicia (Spain), at the beginning and at the end of the intervention program. The results showed that there were statistically significant differences before the application of the intervention program with respect to the quarter of birth in MD (p = .013); A&C (p = .02) and TTS (p < .001) but not in Bal (p = .137). After the intervention, it is observed that the previous differences disappear [MD (p = .755); A&C (p = .806); TTS (p = .507)], in addition, all scores are better than before the application of the intervention program. Regarding gender, no statistically significant effect is observed either before or after applying the intervention program on the variables studied. The results obtained suggest that the application of an intervention using balance bikes could positively influence the improvement of MC in preschool children (boys and girls) and reduce the differences produced by the RAE.

Objetivou-se analisar a experiência de discriminação racial sofrida por estudantes universitários. Estudo exploratório, descritivo e transversal, com abordagem quantitativa, com 751 participantes. Realizado em cinco instituições públicas e privadas de ensino superior do estado do Ceará, Brasil, de setembro a dezembro de 2023. O instrumento utilizado foi a Escala de Experiências de Discriminação Racial e o questionário do perfil sociodemográfico. A identificação e abordagem para pesquisa aconteceu de forma on-line e presencial. Destacaram-se, como maioria, participantes do sexo feminino, 52,5%; com idade média de 22,8; com predominância da raça parda, 58,5%; com renda familiar de um a dois salários-mínimos, 36,9%; e a religião católica com predominância de 59,4%. Com relação ao tratamento injusto relacionado à discriminação racial, observou-se que os participantes afirmaram tomarem alguma atitude ao serem tratados injustamente, como, por exemplo, falavam com outras pessoas. Em relação a sentir-se tratado injustamente e tentar fazer alguma coisa sobre isso, apenas 24,7% da população preta faziam alguma coisa contra isso, em contrapartida, 21,5% guardavam esse tipo de tratamento para si. Além disso, as experiências de discriminação racial por raça em estudantes universitários ressaltaram que 81,7% da população preta já sofreu com discriminação. Observaram-se as preocupações em torno da discriminação racial por raça entre os estudantes, com cerca de 80,6%, no último ano, com 91,4% que prestaram preocupação com o grupo racial e 90,3% que demonstraram autopreocupação ao tratamento injusto. Ademais, 4,3% da população preta já prestou queixa policial, em contrapartida, 95,7% da população preta nunca prestou queixa, fato que demonstra que ainda, atualmente, existem grandes vulnerabilidades vivenciadas, a partir da discriminação racial entre estudantes universitários.

Pemberian izin perkebunan sawit membawa berbagai dampak negatif dalam berbagai segi. Selain kerusakan lingkungan yang pasti ditimbulkannya, juga menimbulkan banyak terjadi kebocoran dalam penerimaan keuangan negara yang seharusnya diterima oleh Negara. Seharusnya izin merupakan instrumen pengendali dalam pengusahaan perkebunan sawit agar sesuai dengan makna filosofis sebagaimana diamanatkan Pasal 33 ayat (3) UUD 1945. Makna yang terkandung dalam Pasal tersebut adalah prinsip “kewenangan Menguasai Negara” terhadap sumber daya alam dan amanat “untuk sebesar-besarnya kemakmuran rakyat”. Kedua hal itulah yang kemudian harus dijadikan dasar dalam penyusunan berbagai kebijakan baik yang bersifat mengatur (regeling) maupun yang bersifat menetapkan (keputusan/perizinan). Terkait perizinan, sudah diberikan sejak pemerintah Hindia Belanda dengan bentuk “Konsesi” sebagaimana diatur dalam Indische Mijnwet 1899. Karena itu jurnal ini ingin mencari bentuk pengusahaan (termasuk perizinan) yang sesuai dengan konsep kewenangan Menguasai oleh Negara sesuai Pasal 33 ayat (3) UUD 1945.

Tujuan dari penelitian ini adalah untuk mendeskripsikan dan menganalisis kedudukan anak angkat terhadap hak waris yang ditinjau dari hukum islam. Dengan menggunakan pendekatan normatif,disimpulkan bahwa kedudukan anak angkat dalam sistem hukum islam tidak dapat mewarisi harta waris dari orang tua seluruhnya,meskipun si pewaris telah membuat surat wasiat.Karena dalam hukum islam anak angkat mendapat bagian paling banyak hanya 1/3 bagian dari keseluruhan harta pewaris.Dan tidak seharusnya pewaris membuat surat wasiat demikian,sudah seharusnya pewaris mengetahui hak dan kedudukan anak angkat. Hasil penelitian ini merupakan hasil untuk menunjukan penjelasan dari beberapa kesimpulan yang diutamakan dari segi hukum positif di Indonesia atau berasaskan berdasarkan aspek yuridis yang terhubung dengan hukum islam yaitu seorang anak angkat tidak dapat mewarisi harta orang tua angkatnya yang diberikan surat wasiat menurut Pasal 209 ayat (2) KHI.

The disease caused by pathogenic bacteria is one of the main problems in aquaculture in the Jambi Province. One of the diseases that occurs in cultivated catfish is due to infection by bacteria Edwardsiella tarda and Edwardsiella ictaluri, which cause Edwardsiellosis with a mortality rate above 50%. The antibacterial properties of the sappanwood extract (Caesalpinia sappan, L.) can be used to overcome problems in aquaculture, while reducing the use of antibiotics that can have negative impacts. This research aims to explore the antibacterial potential of sappanwood extract (Caesalpinia sappan, L.), a local plant believed to possess strong antimicrobial activity. The study began with isolating bacteria from catfish that showing symptoms of the disease, identifying the test bacteria, followed by extracting sappanwood using 96% ethanol solvent. Subsequently, the antibacterial activity was tested using the disc diffusion method with extract concentrations of 1%, 5%, and 10%. The research results indicate that sappanwood extract at a concentration of 5% has a very strong ability to inhibit the growth of  E. tarda and E. ictaluri bacteria. The inhibition zones produced show significant antibacterial activity equivalent to the antibiotic ciprofloxacin used as a positive control.

Instytucja przedstawiciela i gwaranta w postępowaniu celnym
Authors: Laszuk Mirosława
Published: April 2024

Po wejściu w życie rozporządzenia Parlamentu Europejskiego i Rady (UE) nr 952/2013 z dnia 9 października 2013 r. ustanawiającego unijny kodeks celny , a tym samym wprowadzeniu nowych zasad postępowania celnego, pojawiły się problemy z określeniem stron tego postępowania. Przepisy wspomnianego aktu prawnego nie zawierają wyjaśnienia pojęcia „strony postępowania”. Problem dotyczy przede wszystkim przedstawicieli celnych (bezpośredniego i pośredniego) oraz gwaranta. Każdy ze wskazanych podmiotów posiada status podmiotu postępowania celnego. Status strony postępowania posiada jedynie przedstawiciel pośredni, a przedstawiciel bezpośredni tylko w sytuacji, którą określa art. 77 ust. 3 u.k.c. Gwarant, mimo że uiszcza kwotę należności celnych w zastępstwie dłużnika, nie jest stroną postępowania.
Bezumowne korzystanie z budynku a podatek od przychodów z budynków
Authors: Jamróz Krzysztof
Published: April 2024

Przedmiotem niniejszego artykułu jest podatek od przychodów z budynków, uregulowany w ustawach o podatkach dochodowych. Jedną z przesłanek opodatkowania jest to, by budynek został oddany do używania na podstawie umowy najmu, umowy dzierżawy lub innej umowy o podobnym charakterze. W praktyce stosowania prawa podatkowego wątpliwości może wzbudzać to, czy w przypadku korzystania z budynku mimo braku takiej umowy (tj. w przypadku bezumownego korzystania z budynku) przychód będzie opodatkowany. Często taka sytuacja występuje, gdy np. umowa najmu wygasła, a używający dotychczas podmiot płaci nadal wynagrodzenie właścicielowi budynku.
