title: Colonization of intraradical structures of arbuscular mycorrhizal fungi by dark septate endophytic fungi

description: Abstract Extraradical spores of arbuscular mycorrhizal (AM) fungi are often parasitized by a wide range of soil microorganisms. However, reports on the parasitization of intraradical structures of AM fungi are very rare. While examining AM colonization in roots of Cuminum cyminum and Sambucus nigra growing in the medicinal plants garden of the Centre of Medicinal Plants Research in Homeopathy of the Nilgiris, we found that AM fungal hyphal coils, arbusculate coils, vesicles, and intraradical spores are colonized by dark septate endophytic (DSE) fungi which were co-occurring with AM fungi. The AM fungal hyphae were significantly wider than the DSE fungi. Colonization of different AM fungal structures significantly varied between the two plant species. Moreover, the percentage of colonized AM fungal structures was linearly correlated to the abundance of these structures. The colonization of the intraradical structures of AM fungi is illustrated and the significance of this phenomenon needs further elucidation.

title: Straw management effects on global warming potential and yield-scaled greenhouse gas emissions in a subtropical rice ecosystem

description: ABSTRACT Global warming potential (GWP) of rice paddies depends on straw management. This study evaluated methane (CH4) and nitrous oxide (N2O) emissions and soil C stocks to determine GWP and yield-scaled GWP under different strategies and intensities of rice straw management in a subtropical climate. We hypothesized that decreasing soil management intensity and straw incorporation in the soil would reduce GWP. Methane fluxes were substantially higher during the rice growing season than in the off-season, while the opposite was observed for N2O fluxes. The cumulative emissions of CH4 during the growing season among the straw management strategies evaluated ranged from 165.8 to 586.0 kg ha-1. Annual CH4 emissions were lower when soil and straw received some type of management compared to no-tillage. Daily N2O fluxes ranged from -2.8 to 201.7 g ha-1 day-1; cumulative N2O emissions during the off-season ranged from 455.2 to 2816.5 g ha-1. During the off-season, strategies to reduce N2O emissions include post-harvest straw incorporation using a disc harrow, winter straw removal, and ryegrass cropping. Soil organic C stocks ranged from 35.96 to 38.36 Mg ha-1. Straw management using a disc harrow reduced soil organic C stocks, with more adverse effects than straw removal. Soil and rice straw management did not affect rice grain yield, with an average of 10.4 Mg ha-1. Methane emissions were the main component of GWP in all straw management systems. The contribution of N2O emissions to GWP was small and mostly (&gt;85 %) determined by off-season emissions. Yield-scaled GWP ranged from 0.64 to 1.06 Mg CO2eq Mg-1 yield and was lower when soil and straw management systems occurred shortly after the rice harvest. Our results indicate that soil and straw management immediately after rice harvest reduces CH4 emissions, GWP, and yield-scaled GWP.

title: BE BRAVE, LIVE: REVIEWING BUFFY’S JOURNEY IN BUFFY THE VAMPIRE SLAYER FROM FINAL GIRL TO HEROINE TWENTY-FIVE YEARS LATER

description: Abstract The present paper discusses the United-Statesian TV show Buffy the Vampire Slayer reassessing its protagonist, Buffy Summers, in 2022, twenty-five years after its first broadcasting. As a teenage girl turned into a vampire/demon hunter, Buffy undergoes significant changes in relation to her calling as a slayer. Reluctant at first, she comes to terms with her responsibilities later in the series, in a movement that echoes Joseph Campbell’s definition of the monomyth. The authors propose to discuss Buffy’s changes throughout the series, emphasizing key narrative moments, in order to illustrate how the character evolves from what could be perceived as an archetype similar to the “final girl” to a (feminist?) heroine. Additionally, the authors comment on the abuse allegations against Buffy’s creator Joss Whedon, and how they relate to the series’ legacy twenty-five years later.

title: Downward trend in real agricultural input prices

description: ABSTRACT This paper deals with the reduction of prices in agriculture trying to make sense of their relation to inputs’ prices. We understand that even with the reduction in final prices, the equally important reduction in inputs prices acted to soften the losses and may help agriculture to regain productivity.

title: Effect of genetic polymorphisms rs2301113 and rs2057482 in the expression of HIF-1α protein in periodontal ligament fibroblasts subjected to compressive force

description: Abstract Objective Many genes and signaling molecules are involved in orthodontic tooth movement, with mechanically and hypoxically stabilized HIF-1α having been shown to play a decisive role in periodontal ligament signaling during orthodontic tooth movement. Thus, this in vitro study aimed to investigate if genetic polymorphisms in HIF1A (Hypoxia-inducible factor α-subunits) influence the expression pattern of HIF-1α protein during simulated orthodontic compressive pressure. Methodology Samples from human periodontal ligament fibroblasts were used and their DNA was genotyped using real time Polymerase chain reaction for the genetic polymorphisms rs2301113 and rs2057482 in HIF1A . For cell culture and protein expression experiments, six human periodontal ligament fibroblast cell lines were selected based on the patients’ genotype. To simulate orthodontic compressive pressure in fibroblasts, a 2 g/cm2 force was applied under cell culture conditions for 48 hours. Protein expression was evaluated by Western Blot. Paired t-tests were used to compare HIF-1α expression with and without compressive pressure application and unpaired t-tests were used to compare expression between the genotypes in rs2057482 and rs2301113 (p&lt;0.05). Results The expression of HIF-1α protein was significantly enhanced by compressive pressure application regardless of the genotype (p&lt;0.0001). The genotypes in the genetic polymorphisms rs2301113 and rs2057482 were not associated with HIF-1α protein expression (p&gt;0.05). Conclusions Our study confirms that compressive pressure application enhances HIF-1α protein expression. We could not prove that the genetic polymorphisms in HIF1A affect HIF-1α protein expression by periodontal ligament fibroblasts during simulated orthodontic compressive force.

title: QUALITY OF LIFE OF PHYSICAL EDUCATION TEACHERS IN GRANDE FLORIANÓPOLIS MESOREGION, BRAZIL

description: ABSTRACT Based on the current scenario of accelerating social changes that reflect on the educational context, the discussion on the factors that might influence the quality of life (QOL) of Physical Education teachers is important. With the purpose of evaluating the association between QOL and sociodemographic characteristics, questionnaires on socio-demographic data and quality of life (WHOQOL-bref) were applied to 298 Physical Education teachers of Basic Education in Grande Florianópolis mesoregion, state of Santa Cantarina, Brazil. The Chi-square, Mann-Whitney and Kruskal Wallis tests with Dunn’s post hoc method (p &lt;0.05) were used for data analysis. The Physical Education teachers showed regular scores related to the general QOL; higher values for the social relations domain and lower ones for the physical domain. Some characteristics, such as sex, vital cycles, length of service in the school system, work shift, population number and the Human Development Index (HDI) of the municipalities were correlated with general QOL, as well as with the physical, psychological and environmental domains. It is concluded that QOL is associated with the socio-demographic characteristics of Physical Education teachers; thus, this should be taken into consideration when thinking of educational planning and management in Basic Education.

title: The Sonic Common Wind: Hearing the Communitarian Relations and the Migratory Movements of the Haitian Revolution in the Jazz of Haiti and New Orleans

description: Abstract Music has been a force for social cohesion and a site of politicized consciousness for the migrants of the Haitian diaspora as early as the outbreak of the Haitian Revolution (1791-1804). This essay explores Vodou Jazz movement of Haiti during and after the United States occupation (1915-1934) by connecting this 20th century movement to Haitian migration to New Orleans in the early 19th century. Both are expressions of transcarribean culture (“the common wind”) which spread the news and militancy of the Haitian Revolution through popular song and dance. Rather than passive victims to enslavement, forced migration, and economic imperialism, this essay demonstrates how multiple transnational communities made sense of their world through a sophisticated aural culture which challenged imperialism, slavery, and the plantation mode of production.

title: Shear and punching shear according to the Critical Shear Crack Theory: background, recent developments and integration in codes

description: Abstract The Critical Shear Crack Theory (CSCT) has been developed since 1985 to assess the shear resistance of members without shear reinforcement and the punching shear resistance of reinforced concrete slabs in a rational manner. The main idea of the CSCT is that the shear resistance is governed by the development of a critical shear crack, its geometry and its kinematics. Recent shear tests with detailed measurements have confirmed that the shear force can be carried through the critical shear crack by a combination of aggregate interlocking, residual tensile strength of concrete, dowel action of the longitudinal reinforcement, inclination of the compression zone and activation of the shear reinforcement crossed by the critical shear crack if present. On the basis of advanced constitute laws, all these contributions can be calculated as a function of the crack geometry and its kinematic. Simplifications of the resulting general formulations have been implemented in several standards including the fib Model Code 2010 and, in its recent closed-form format, in the second generation of the European Standard for Concrete Structures. The generality of the models allows accounting for several materials and cases, as for instance the presence of axial forces, fiber reinforced concrete, non-metallic reinforcements and designing strengthening using several techniques. This document presents the historical framework of the development of the theory, followed by a short presentation of its most up-to-date refined models. The derivation of closed-form solutions based on the CSCT and how it leads to expressions in a format similar to the current European Standard for Concrete Structures is also discussed. Eventually, for the case of punching, some recent developments are shown in what refers the capability of the refined mechanical model to capture the relationship between the acting punching load, the rotation and the shear deformation during loading and at failure.

title: FAMILIES' VIEWS ON PHYSICAL EDUCATION: A DESCRIPTIVE STUDY

description: ABSTRACT It is clear that physical education is considered a compulsory subject and as such should be la-belled as an important subject, but this perspective is not always shared by the educational community. The aim of this study was to explore the perception of families with children enrolled in compulsory education about the subject of physical education. To this end, an ad hoc questionnaire was administered, consisting of 15 questions, two of which were socio-demographic in nature and the rest of which were Likert-type responses. The study is a non-experimental, descriptive, cross-sectional study. The study sample consisted of a total of 120 respondents (M=40.28 years; SD= 6.95). Participants were selected through non-probability purposive sampling. The results showed a lack of knowledge regarding the subject of physical education which implies that there are diverse opinions about the functioning and the proposed aim of this subject. However, physical education should be seen as an essential subject for the integral development of the student.
