Abstract
The benzylisoquinoline alkaloids of Annona muricata have been isolated, but their physiological or ecological role is unknown. The objective was to explore whether these secondary metabolites are involved in defense against phytopathogenic fungi. To do this, the alkaloidal response of 6-leaf seedlings of A. muricata was analyzed, previously inoculated with Colletotrichum gloeosporioides and Rhizopus stolonifer. Before and after inoculation, alkaloidal extracts of roots, stems, and leaves were obtained, and the antifungal activity was evaluated in vitro. The alkaloids anonaine, reticuline, nornuciferine, assimilobine, and coreximine were identified. C. gloeosporioides caused variable increases in the production of anonaine, reticuline and nornuciferine (10–1200%), while R. stolonifer only stimulated the increase of nornuciferin and anonaine (10%) in the stems and leaves. The alkaloidal extracts of inoculated seedlings increased the antifungal activity, both against the pathogen elicitor and against the second target pathogen. These findings suggest that the alkaloids participate in the antifungal defense mechanism.

Abstract
The substitution of portland clinker by supplementary cementitious materials (SCMs) is one of the main avenues for the further decarbonization of cement production. To secure future SCM supplies, generic and performance-related test methods for SCMs are required. The International Union of Laboratories and Experts in Construction Materials, Systems and Structures (RILEM) Technical Committee 267-Tests for Reactivity of SCMs (TRM) recommended the so-called R3 test methods for SCM reactivity testing and ASTM adopted the test as ASTM C1897-20, Standard Test Methods for Measuring the Reactivity of Supplementary Cementitious Materials by Isothermal Calorimetry and Bound Water Measurements, in 2020. This paper presents the results of an interlaboratory study (ILS) that was carried out to develop precision statements for the ASTM C1897-20 test methods. The ILS was conducted and interpreted according to ASTM C802-14, Standard Practice for Conducting an Interlaboratory Test Program to Determine the Precision of Test Methods for Construction Materials, and precision statements were prepared following ASTM C670-15, Standard Practice for Preparing Precision and Bias Statements for Test Methods for Construction Materials. The ILS involved the testing of three centrally supplied conventional SCMs by both test methods (R3 hydration heat and bound water) by at least eleven labs. The processing and analysis of the ILS data for single-operator and multilaboratory precision are presented.

Published: August 2022

Biological systems are subject to a dramatic increase in invading species in the 21st century due to increasing globalization around the world. In the near future, these species will cause more extensive ecological as well as socio-economic damage. Biotic invasions will result not only in a reduction of the original biodiversity, but also total loss, particularly degradation of natural habitats – especially Natura 2000 habitats. This study aims to understand the processes of spread of invasive plant species, their way of life, adaptation to environmental changes and displacement of native species. Without the local level, it is not possible to understand these processes on the regional and continental dimensions and thus implement scientific facts and findings into the prediction of the development of global biosystems. The research was conducted during the vegetation period in the years 2017–2021 in the studied areas of non-forest and forest habitats in the central part of Slovakia. We recorded 242 localities in the area with the occurrence of invasive plant species in an area of 3.057 km2 out of the total mapped area of 169.024 km2. We recorded the highest number of localities and the most expansive distribution for the species Stenactis annua, Robinia pseudoacacia, Solidago canadensis, Impatiens glandulifera and Fallopia japonica.
Cenopopulation of Epipactis helleborine (Orchidaceae) in forest ecosystems that have been anthropogenically transformed to various degrees
Authors: Chornous O. P. 
Published: August 2022

Because of developed symbiotic connections of the root system of trees, mycorrhiza-forming fungi and the orchid family Orchidaceae in forest ecosystems of the northeast Polissia Region – cultivated Pinus sylvestris, which are now 100–120 years old, recovery of cenopopulations of Epipactis helleborine has been observed in locations of mixed and broad-leaved forests. In natural plant cover of mature pines of the region, indigenous vegetation is gradually recovering – there occur young Quercus robur, Tilia cordata, Acer platanoides of various ages, crown density of understory formed by Coryllus avellana has reached 0.6, above-ground organic leaf foliage that is able to sustain moisture and increase fertility of soil accumulates, creating sufficient conditions of shading for seedlings and juvenile individuals of forest orchids. Special studies revealed a relationship between density of E. helleborine specimens and crown density of the tree stand, shrub strata, structure of soil cover, expressed in cenoses under various degrees of recreational pressure. Density of individuals of forest orchids in the studied populations ranges 10.0 to 0.1 ind./10 m2. Dynamics were seen in groupings of Betuleto-Pineta corylosa, Querceta (roboris) corylosa, Querceto-Pineta corylosa, Acereto (platanoidis) –Tilieto (cordatae) – Quercetum (roboris) aegopodiosum in the territory of the nature-reserve fund and structurally similar anthropogenically pressurized cenoses. We determined that all examined cenopopulations in old indigenous zonal cenoses in the territory of the nature reserve fund are normal, they may be considered relatively stable, ontogenetic spectra are incomplete, mostly with right-sided age spectrum – maximum numbers of virgin and generative individuals of various stages. Low density of individuals and incomplete spectra of cenopopulations in light oak forests are natural, and now the largest share of generative and virgin individuals is concentrated in this area. Impact of recreation, unavoidable due to proximity to a road, is a negative factor directly decreasing their density. Ontogenetic spectra of all cenopopulations are incomplete – no seedlings were found in the natural conditions due to underground type of germination. Much more interesting data may be obtained by monitoring studies of age and morphometric dynamic changes during several years.

Introdução: Cirurgia bariátrica é um importante tratamento para a obesidade severa. Como ansiedade e estratégias de enfrentamento insatisfatórias estão associadas à obesidade, é importante avaliar o comportamento de pacientes candidatos e submetidos à cirurgia bariátrica, uma vez que esta pode ter impacto negativo sobre os resultados desse procedimento. Objetivo: avaliar ansiedade, depressão, estratégias de enfrentamento e qualidade de vida pré e pós-cirurgia bariátrica a partir dos dados da avaliação psicológica. Método: Estudo descritivo, longitudinal, com 118 pacientes atendidos no Ambulatório de Cirurgia Bariátrica de um hospital de ensino de alta complexidade, que realizaram o procedimento entre janeiro/2011 e janeiro/2015. Foram utilizados dados primários (avaliação psicológica pós-cirurgia) e secundários (relatório da avaliação psicológica pré-cirurgia). A avaliação psicológica incluiu: questionário socioeconômico, Escala Hospitalar de Ansiedade e de Depressão (HAD), Questionário de Qualidade de Vida SF-36 e Escala de Modos de Enfrentamento de Problemas (EMEP). Resultados: A média de idade dos pacientes foi 40,1 anos e houve predomínio de mulheres (n = 105, 89%). Houve redução significante dos sintomas de depressão após a cirurgia (p<0,001) e aumento em todos os domínios de qualidade de vida do SF-36. Após a cirurgia, houve aumento no uso de estratégias de enfrentamento focadas no problema, redução das estratégias de enfrentamento focadas na emoção e em práticas religiosas e suporte social. Conclusão: A comparação dos níveis de ansiedade, depressão e qualidade de vida mostraram-se melhores após a cirurgia. Houve aumento do uso de estratégias de enfrentamento focadas no problema.

“LO MISMO PUEDEN SER RUSOS BLANCOS, JUDÍOS ALEMANES O COMUNISTAS ESPAÑOLES O ITALIANOS” : LOS PASAPORTES NANSEN EN LAS LEYES DE EXTRANJERÍA DEL ECUADOR.
Authors: Rodríguez Bustamante Agatha 
Published: August 2022

Este artículo propone analizar y explicar cómo, para qué y por quiénes fueron utilizados los pasaportes Nansen en el marco de las leyes de extranjería del Ecuador entre 1921 y 1941. A través del análisis de este marco legal observaremos las políticas que se implementaron para posibilitar la entrada de extranjeros considerados “útiles”. Para lograr este objetivo reconstruiremos la actuación de los cónsules ecuatorianos frente a los extranjeros que solicitaron inmigrar “bajo el amparo” de los documentos Nansen u otros certificados, sin observar si eran “rusos blancos, judíos alemanes o comunistas españoles o italianos”. Esta expresión fue usada para explicar los procedimientos de otorgamiento de visas a apátridas, condición que adquirieron debido a conflictos que Ecuador consideraba lejanos. Lo que venía siendo un procedimiento de facto, se regularizó a finales de la década de 1940. Para ese entonces decenas de inmigrantes salvaron sus vidas por el “vacío legal” de las leyes ecuatorianas.

Authors: Vancu Gabriela Sorina , Egerau Anca Manuela 
Published: August 2022

The Covid 19 pandemic, is a period with a strong impact in all areas of the families, their social, economic, political and educational life. The rules and sanitary measures to prevent the spread of the pandemic, the educational policies, as well as the isolation, quarantine of some teachers, imposed the transition from classical education to online one. This transition, and also the need for digitalization, have led to major changes in teaching activity and implicitly have affected the well-being of teachers. The present study investigates the psychological reactions of 73 teachers as well as the effectiveness of a psychological intervention applied to 15 teachers, who showed severe psychological reactions during the pandemic period. The motivation of the study derives from the need to offer quick methods and techniques for managing the emotional states they went through.
The psychological intervention model presented in the article, aims to reduce the symptoms of stress, anxiety and depression that teachers experience during a pandemic situations, and also to help them apply psychological intervention techniques to regain their well-being).

The quality of the education system is the foremost factor for the success of the students as well as the academia at large, and therefore, needs the focus of regulators and researchers alike. The current article investigates into the role of human resource (HR) quality and Kaizen on the quality assurance system in the context of the high school environment in Indonesia. The current research also analyzes the moderating role of national higher education policies among the associations of HR quality, Kaizen and the quality assurance system in the high school environment in Indonesia. The primary sources of data collection have been adopted by the researchers using survey questionnaires. The medical students are the respondents targeted by the researchers selected based on purposive sampling. The researchers have adopted primary data analysis tools such as Smart-PLS to test the hypotheses and check the validity and reliability of the items and constructs. The findings indicated that HR quality and Kaizen have a positive association with quality assurance systems within the high school environment in Indonesia. The outcomes also revealed that national higher education policies significantly moderate among the association of HR quality, Kaizen and quality assurance system in the high school environment in Indonesia. These outcomes provide valuable insights for policymaking regarding assessment and improvement of the quality assurance system in the education sector in the country.
Keywords: Human resource quality, Kaizen, quality assurance system, national higher education policies, medical student

Authors: Moftah Heba M. , Turkmani Ibrahim , Darwich Khaldoun 
Published: August 2022

Objective: To evaluate the effect of glass fibers on acrylic resin fracture strength in simulated implant-supported overdenture (IOD) abutments.
Methods: A model was designed to simulate the clinical situation of an IDO (50 12 1.5 mm). Thirty models were divided into three equal groups: ten models not supported with glass fibers (control group), ten models with one layer of glass fibers (experimental group I) and ten models with two layers of glass fiber (experimental group II). All models were exposed to a three-point bending test, and fracture loads were analyzed using a one-way analysis of variance (ANOVA) followed by Bonferroni post-hoc test.
Results: IOD models reinforced with two layers of glass fibers (experimental group II) showed a mean ultimate load at fracture of 48.69 ± 3.71 Newton (N) compared to mean loads of 32.78 ± 2.41 N and 24.42 ± 2.73 N for the models reinforced with one layer (experimental group I) and non-reinforced with glass fibers (control group), respectively. ANOVA showed a statistically significant difference between the three groups regarding the mean ultimate load at fracture, and Bonferroni post-hoc test showed statistically significant differences between both experimental groups and the control group as well as between experimental group I and experimental group II.
Conclusions: The fracture strength of IDO abutments increases significantly by the addition of acrylic resin pre-impregnated with glass fibers, even when the thickness of acrylic is thin.

Published: August 2022

Abstract
Background: Health systems need to be evaluated to ascertain if they are meeting their objectives. There is an increased interest in health system responsiveness (HSR) as a means to appraise health systems. This becomes vital as we put people at the centre of integrated health systems and put a premium on their rights and perspectives. Thus, this study assessed the levels, distribution and factors associated with HSR in Oyo State.Methods: The study was a cross-sectional study with 717 adults who had used an out-patient health facility in the preceding 12 months interviewed using a semi-structured, interviewer-administered questionnaire. HSR was measured on a multi-domain and multi-item (7 domains and 20 items) 5-point Likert scale that was developed by the WHO to measure HSR globally. Summary scores were computed for level, distribution and the most important domains of HSR. Determinants of poor HSR were determined using binomial logistic regression. The level of statistical significance was set at 5%.Results: The overall level of HSR was 47%. The highest-rated domains were confidentiality (72%), dignity (64%) and choice (60%), while the least rated were prompt attention (43%) and communication (52%). The overall distribution of HSR was 0.228 (range of 0 to 1) with the domains of prompt attention (0.595) and choice (0.506) being the most unequally distributed. The most important domains were communication, prompt attention and dignity. The least important domains were choice and confidentiality. The factors associated with poor HSR (overall) were no formal education, (OR=2.81; 95% CI: 1.35-5.86), primary as the highest level of education (OR=2.19; 95% CI: 1.28-3.75), poor socioeconomic class (OR=1.86; 95% CI: 1.23-2.80), using a government-owned facility (OR=1.56; 95% CI: 1.11-2.19) and not using the usual health facility (OR=1.69; 95% CI: 1.13-2.53).Conclusion: The overall level of HSR in Oyo State was low with the domains of prompt attention, communication and autonomy being the least rated domains. Therefore, concerted efforts should be targeted at improving HSR as this will improve wellbeing, health system utilization, and the overall health system.
