Published: July 2022

Introducción: Los indicadores de calidad de la dieta (Diet Quality Indicators, DQIns) son herramientas para evaluar las características de patrones de dieta basados en el conocimiento de la relación entre los factores dietéticos, los estilos de vida y resultados de salud. El objetivo de este artículo fue proponer un nuevo índice de calidad de la dieta utilizando un enfoque a priori para su aplicación en residencias de ancianos, Quality Index for Nutrition in Nursing Homes, índice QUINN.
Metodología: La elección de los componentes se basó en una revisión rápida realizada sobre índices previamente publicados y los principales grupos de alimentos relacionados con la prevención de síndromes geriátricos y de las enfermedades crónicas de alta prevalencia en población geriátrica. El índice QUINN se basó en 15 componentes dietéticos-alimentos, 12 de los cuales se referían a alimentos básicos de una dieta saludable (verduras, frutas, legumbres, aceite de oliva – preferiblemente virgen extra-, cereales, lácteos, pescados blancos y mariscos, carnes blancas y huevos, componentes positivos); otras grasas, carnes rojas y procesadas y dulces, componentes negativos), junto con otros 3 componentes adicionales positivos (variedad de verduras y frutas, pescado azul y cereales integrales). Cada componente se clasificó en 4 categorías (0, 1, 2 o 3 puntos), con un rango final de 0 a 45 puntos.
Conclusiones: Desde nuestro conocimiento el índice QUINN es el primer índice de calidad de la dieta a priori desarrollado específicamente para evaluar los menús ofertados en las residencias de ancianos. Esta herramienta proporcionará información sobre la calidad de la dieta para el diseño de los menús. El índice QUINN podría ser un instrumento útil para implementar estrategias de intervención para mejorar de forma sencilla la dieta ofertada en las instituciones y que redundar en mejora del estado nutricional y la salud de la población geriátrica institucionalizada.

Objective: The present study aims to assess the associations of adductor pollicis muscle thickness (APMT) with age, skin color, sexual maturation, anthropometric indicators and physical activity in Brazilian adolescents.
Materials and methods: Cross-sectional study of adolescents aged 14-19 years. Weight, height, body mass index (BMI), arm circumference (AC), APMT, body fat, fat-free mass (FFM), fat-free mass index (FFMI), sexual maturation, time of physical activity and skin color were evaluated. APMT was associated with categorical variables using Mann-Whitney or Kruskal-Wallis tests and correlated with anthropometric variables using Spearman’s correlation. Linear regression was used with APMT as a dependent and the other variables as predictors. Data analysis was carried out in SPSS® software (version 17.0) with a 5% significance level.
Results: 828 adolescents were evaluated, 57.6% female, with a mean age of 16.13 ± 1.20 years. APMT had an average value of 18.0 mm in females and 21.0 mm in males. The measure was greater in males, in more advanced stages of sexual maturation, overweight and physical activity. It presented a moderate correlation with FFM, FFMI, body fat and AC. In the final model of multiple linear regression for females, the variables AC and body fat explain 20.1% of the APMT variability. For men, the variables AC and FFMI explain 30.5% of the APMT variability.
Conclusion: It is recommended that APMT be used in a complementary manner in the nutritional assessment of adolescents.
Education and equalities in Britain, 2010–2022: due regard and disregard in a time of pandemic
Authors: Richardson Robin
Published: July 2022

This article recalls the key concept of due regard in the Equality Act 2010 and outlines how it was increasingly ignored by the Department for Education (DfE) in England in the following decade. Further, it speculates that if the concept of due regard had been observed more rigorously across all government departments, the COVID-19 pandemic would have been less tragic and traumatising in its effects, and less responsible for deepening inequalities throughout British society. It concludes that the Act should be revisited, revised and re-emphasised.
Notes from Archive to AR: towards a creative knowledge exchange
Authors: Hannay Zelda
Published: July 2022

Archive to AR was a knowledge exchange project that took place during 2019 and 2020, and which was funded in its second phase by an XR Stories Small Collaborative R&D grant. A collaboration between the University of Sheffield, Sheffield-based digital agency Hive IT, and the National Railway Museum, its aim was to develop an idea and partial prototype for a mixed-reality game based on the National Railway Museum’s archive, which could be played on a phone or a tablet. Drawing on my experience as a practitioner-academic working on Archive to AR, the aim of this article is to present and reflect upon the creative practice-related methodological outcomes of the project. My intention is to consider which principles for doing knowledge exchange (KE) emerge when embodied, creative process is prioritised and, in line with a practice-as-research approach, the KE space is cast as a site of knowledge production as well as exchange. Part provocation, part ethno-autographic reflection and part analysis, this paper’s overall aim is to contribute to the ongoing conversation about how KE and creative work can overlap within a new ‘third space’ for academia in a way that prioritises process and method, but which is nevertheless conducive to high-quality artistic outputs.

Authors: Lima Fabiano Guasti , Paulino Carolina Trinca , Silveira Rodrigo Lanna Franco , Gatsios Rafael Confetti , Neto Alexandre Assaf
Published: July 2022

In the face of the latest world financial crises, the ratings released by the regulatory agencies have gained distinction in the financial market.  This paper proposes models to predict the future ratings of companies and countries. The analysis was carried out using quarterly data from 2010 to 2018 from companies in Brazil, South Africa, Germany, Argentina, Australia, Canada, Chile, China, Colombia, South Korea, the United States, France, Italy, Japan, Mexico, Peru, the United Kingdom, Russia, and India. The sample's number of companies and countries is limited to the availability of rating information and the other model information. We use the panel-ordered logit model for classifying the rating and the other economic and financial variables as an independent.  The results show that the financial and economic variables are essential to predict the rating of financial and non-financial companies in Brazil as well as the sovereign rating of the sample countries. The predictive capacity of the models reached values close to 80%, emphasizing the forecasts of large banks with 94% accuracy. For the country sample, the results are close to 80% accuracy. With the results of the research, improvement in the financial and economic indicators and the increase in the predictive capacity of the market agents for the prior determination of future ratings of financial companies are expected.

The method used in this research is descriptive qualitative with literature review research method. The theory used in this research is sexism theory by Natasha Walter. The results of this research indicate that there are two acts of sexism, namely 1) sexual violence which includes sexual harassment and sexual objectification, and 2) violence. Based on the results of data analysis, it can be concluded that there are depictions of acts of sexism against women. Based on the results of data analysis, it can be concluded that in the collection of short stories by Edogawa Rampo there are depictions of acts of sexism against women that occur because of gender stereotypes that give rise to a culture of domination that develops in society. The perception of subject-object and superior-inferior in the culture of domination, in which women are considered weak creatures and men are stronger beings, is a factor in the occurrence of violence against women.

Authors: Pradhana Ngurah Indra
Published: July 2022

This research is entitled, "The Effect of Demographic Transition on the Needs for Foreign Workers in Japan". The data from this study are from the distribution of questionnaires to students at Kobe Women's University-Japan and the results of interviews from a number of informants in Japan. From the distribution of the questionnaire, there were 70 data related to this research. Specifically, the purpose of this study is to answer the Japanese public's response to the need for foreign workers in Japan and the type of work that dominates foreign workers in Japan. This research will be studied from a socio-cultural point of view. The method used is an open questionnaire and a closed questionnaire with an advanced technique, namely interviews. The results of this study are that of the 70 informants, 60 people responded that Japan was being dominated by foreign workers and 10 more people said they did not agree with the statement. Regarding the dominant occupations carried out by foreign workers in Japan, among others, health workers for the elderly, manufacturing, shopkeepers who are open until late, and restaurants. The point is that it is a job field that is rarely liked by Japanese people and for foreign workers who do not use Japanese much while working. However, foreign workers who want to work in Japan should understand the culture and customs of Japanese society.

Student Centered Learning, or hereinafter abbreviated as SCL, is present as a solution to the problem of incompatibility of Teacher Centered Learning learning methods. SCL emphasizes the student-centered learning process, where in this approach, students become active actors in learning activities. The presence of the student-centered learning method is expected to be able to improve the quality and learning abilities of school students. This study aims to determine the effectiveness of learning Japanese with poster media to improve the Japanese reading ability of students in class XI Language at SMAN 113 Jakarta. The research method is student-based learning with the research design being Pre-Experimental Design with the One-Group Pretest-Posttest Design model. The study included 40 students from SMAN 113 Jakarta's class XI Language.Data analysis in the study was carried out in several stages, namely the validity test, reliability test, homogeneity test, normality test, t test, and n gain score. The findings revealed that there was a substantial effect or difference in student-based learning using poster media on enhancing Japanese language acquisition reading ability when compared to before treatment. The N Gain Score test, which uses two statistics, the mean and median, shows that the strategy is extremely effective in developing Japanese language abilities.
Surgical repair of the adult form of scimitar syndrome
Authors: Ochiai Yoshie
Published: July 2022

Scimitar syndrome has various clinical presentations and anatomic features, and some cases are diagnosed in adulthood. Reconstruction using autologous tissue to reroute the right pulmonary venous blood flow to the left atrium is ideal. However, if the scimitar vein drains to the caudal segment of the inferior vena cava, reconstruction using prosthetic material may be necessary due to the distance between the left atrium and the scimitar vein. We describe the case of a 16-year-old boy with scimitar syndrome. We anastomosed the scimitar vein to the right atrium using an artificial graft and created an atrial septal defect for rerouting the right pulmonary venous blood to the left atrium. It has been 9 years since this procedure, and the patient has not experienced graft stenosis or thromboembolic events.
Faḫr al-Dīn al-Rāzī on Animal Cognition and Immortality
Authors: Adamson Peter , Somma Bethany
Published: July 2022

This paper is devoted to a fascinating passage in Faḫr al-Dīn al-Rāzī (d. 1210), in which he argues that non-human animals have rational souls. It is found in his Mulaḫḫaṣ fī l-manṭiq wa-l-ḥikma (Epitome on Philosophy and Logic). Following a discussion of the afterlife, Faḫr al-Dīn suggests that animals should, like humans, be capable of grasping universals, and that they are aware of their own identity over time. Furthermore, animal behavior shows that they are capable of rational planning and problem-solving. We contextualize these arguments with reference to Faḫr al-Dīn’s other philosophical works, and also compare the considerations he raises to ideas found in modern-day animal ethics, drawing here especially on the work of Mark Rowlands. The paper concludes with a translation of the passage.
Propionibacterium acnes: an uncommon cause of lung abscess in chronic obstructive pulmonary disease complicated with bullous emphysema
Authors: Adlakha Arun , Muppala Neha
Published: July 2022

A 57-year-old man who had recurrent respiratory infections due to tobacco use and severe chronic obstructive pulmonary disease (COPD) was evaluated as an outpatient to discern the etiology. He was followed with a chest X-ray and a chest computed tomography (CT) scan that displayed a left upper lobe cavitary lung abnormality. The lesion was further evaluated with a CT-guided biopsy, and it was identified as a lung abscess. A tissue culture isolated Propionibacterium acnes. We present a rare case of a common skin commensal, P. acnes, that infected the left upper lobe of the lung. We presume that the patient was predisposed to infection secondary to degradation of pulmonary parenchyma by severe bullous emphysema. This destruction created an inflammatory and colonizing space for organisms, even uncommon forms, to flourish. Initially this presentation prompted a differential of pulmonary tuberculosis; however, with further workup, the diagnosis was excluded. This case highlights the potential of P. acnes, an uncommon lung microbe, to lead to a lung abscess in a patient who was otherwise immunocompetent. This case will allow osteopathic clinicians to detect an uncommon microorganism that can potentially cause a pulmonary abscess in a patient with a medical history of severe bullous emphysematous COPD.
The Logic of Contemporaneity: On Anti-Climacus’s Philosophy of History
Authors: Millay Thomas J.
Published: July 2022

Near the end of Practice in Christianity, Kierkegaard’s pseudonym Anti-Climacus denies that progress occurs within history. We are not getting better every day, in every way. According to Anti-Climacus, we are the same as we have always been. This essay sets Anti-Climacus’s denial of progress in its historical context, arguing that he develops a counter-philosophy of history which combats the prevailing Hegelianism of his age. The essay also draws connections between Anti-Climacus’s philosophy of history and the themes of imitation and contemporaneity, showing how a denial of history’s progress enables contemporary humans to interact with the same world Christ faced.
Kierkegaard’s Strong Anti-Rationalism: Offense as a Propaedeutic to Faith
Authors: Kemp Ryan , Della Torre Frank
Published: July 2022

In a now classic paper, Karen Carr argues that Kierkegaard is a religious “anti-rationalist”: He holds that reason and religious truth exist in necessary tension with one another. Carr maintains that this antagonism is not a matter of the logical incoherence of Christianity, but rather the fact that genuine submission to Christ precludes approaching him through demonstration. In this essay, we argue that while Kierkegaard is in fact an anti-rationalist, the literature has failed to appreciate the full strength of his position. It is not just that reason and obedience are in tension; rather, Kierkegaard holds the stronger view that reason is actively offended by Christianity’s primary claims. Not only is reason incapable of generating any positive evidence for the truth of Christianity, more radically, it provides evidence against it. In order to make this case, we offer a close reading of Practice in Christianity, developing a typology of Kierkegaard’s account of Christ’s “offense.” Finally, having motivated Kierkegaard’s strong anti-rationalism, we consider why, on his account, anyone would want to be a Christian.
Kierkegaard and Religionswissenschaft: A Source- and Reception-Historical Survey (Part 1)
Authors: Ziolkowski Eric
Published: July 2022

The subject of this two-part article (the second part will be published in KSYB 2023) is the bearing of Søren Kierkegaard’s writings, and of their reception, upon the development of Religionswissenschaft or the comparative study of religion. This first part opens by taking account of Kierkegaard’s own awareness of, and relationship to, “non-Christian” religions (Judaism, Islam, Hinduism, Buddhism, religions of China, etc.), including his late reading of Schopenhauer; then considers Kierkegaard in juxtaposition with his contemporary F. Max Müller, the Sanskritist and foundational pioneer of comparative religion, and the two men’s contrasting relations to F.W.J. Schelling; and finally examines the interest taken in Kierkegaard by William James, Max Weber, and Gerardus van der Leeuw as early twentieth-century contributors through three different disciplines to the study of comparative religion.
Heiberg’s Article on History and Kierkegaard’s Critique
Authors: Stewart Jon
Published: July 2022

This article provides an introduction to Johan Ludvig Heiberg’s “On the Principle of the Beginning of History” from 1843. The Danish poet, playwright and critic attended Hegel’s lectures in Berlin in 1824 and returned to Copenhagen a convinced Hegelian. He spent the next two decades pursuing a campaign to spread the word about Hegel’s philosophy in the Kingdom of Denmark. His little-known article on history draws substantially on Hegel’s Lectures on the Philosophy of History, which had been published by Heiberg’s acquaintance Eduard Gans in 1837 as a part of the complete works edition of Hegel’s writings. Kierkegaard makes Heiberg’s article the object of criticism in The Concept of Anxiety and a draft of Prefaces. In the former he claims that Heiberg’s occupation with the beginning of world history trivializes the issue of sin. In the latter he charges Heiberg with plagiarism. The present article introduces Heiberg’s article and gives an account of Kierkegaard’s criticism.

Published: July 2022

Rodents of the genus Cricetomys have been reported to be nocturnal with a bimodal activity pattern and to frequently change burrows. However, no studies to date have examined these ecological aspects with the use of radio-telemetry. Five C. emini were captured and radio-collared to study their activity patterns and burrowing ecology from 9 March to 15 April 2016. Nocturnal activity ranged between the hours of 18:00 and 05:00 with a probable reduction of activities between 20:00–23:00 and around 04:00 with diurnal activity between 06:00 and 17:00 h with a reduction of activity between 11:00 and 14:00. While the present study does confirm nocturnal activity and a bimodal pattern, this study also suggests greater diurnal activity as compared to previous studies. Additionally, data presented here also suggest that C. emini may not change burrows as frequently as previously reported.
LINC00665/miRNAs axis-mediated collagen type XI alpha 1 correlates with immune infiltration and malignant phenotypes in lung adenocarcinoma
Authors: Zhu Jun , Weng Yuan , Wang Fudong , Zhao Jun
Published: July 2022

Collagen type XI alpha 1 (COL11A1) as an oncogene has been reported in several malignant tumors. Herein, we aimed to explore the function of COL11A1 and its upstream regulators in lung adenocarcinoma (LUAD). COL11A1 expression prognostic significance, gene ontology, Kyoto Encyclopedia of Genes and Genomes, and immune infiltration were explored in LUAD. In vitro experimental measurements were implemented to validate the function of COL11A1 and LINC00665 in LUAD cells. Our study demonstrated that LINC00665-2 and COL11A1 were significantly upregulated in LUAD tissues compared with nontumor tissues. COL11A1 was positively correlated with multiple immune cell enrichment, suggesting that COL11A1 may be a prospective therapeutic target to enhance the efficacy of immunotherapy in LUAD. A regulatory mechanism LINC00665-2/microRNAs (miRNAs)/COL11A1 axis was identified to facilitate the tumorigenesis of LUAD. si-LINC00665 transfection induced the inhibition of growth and migration, and apoptosis was reversed by the overexpression of COL11A1 in LUAD cells. In conclusion, LINC00665 as a competing endogenous RNA sponging multiple miRNAs to modulate COL11A1 expression in LUAD, suggesting that LINC00665/miRNAs/COL11A1 axis may contribute to the pathogenesis of LUAD.
Effect of femoral head necrosis cystic area on femoral head collapse and stress distribution in femoral head: A clinical and finite element study
Authors: Zhang Zhaoming , Lin Tianye , Zhong Yuan , Song Wenting , Yang Peng , Wang Ding , Yang Fan , Zhang Qingwen , Wei Qiushi , He Wei
Published: July 2022

The purpose of this study was to investigate the effect of cystic areas of osteonecrosis of the femoral head (ONFH) on stress distribution and disease progression in the femoral head. A total of 85 patients (106 hips) diagnosed with Association Research Circulation Osseous stage II non-traumatic and non-surgical treatment were retrospectively analyzed. The presence of cystic areas and diameter of cystic areas were compared between the two groups. In addition, five spherical cystic areas of different diameters were constructed and the maximum stress was observed. There was a difference between the two groups in whether cystic areas appeared in the femoral head, with 49.1% in the collapse group showing cystic areas, which was significantly higher than that in the non-collapse group (18.4%) (P < 0.05). In addition, the diameter of the cystic areas was significantly larger in the collapsed group than in the non-collapsed group (P < 0.05). The maximum and mean von Mises stress value around the necrotic area and around the cystic area of the femoral head increased with the increase of the cystic diameter. Stress concentration areas can be generated around the cystic areas. The presence and increased diameter of the cystic areas accelerates the collapse of the ONFH femoral head.
All Designators are Rigid
Authors: Noonan Harold
Published: July 2022

In Naming and Necessity Kripke introduces the concept of a rigid designator and argues that proper names are rigid designators. He argues that in this way they are different from typical definite descriptions (though he allows that some definite descriptions, e.g., ‘the actual winner of the lottery’, ‘the square of 3’, are rigid designators). His opponents have either argued that names can be regarded as abbreviations of rigid descriptions (e.g., ‘actualized’ ones) or have tried to deny that names are rigid designators. I shall argue that no unambiguous descriptions are non-rigid. All unambiguous descriptions are rigid. The appearance of non-rigidity in descriptions is simply an illusion, a manifestation of ambiguity. I shall then go on to show that an explanation of the difficulty which has been found in extending the rigid/non-rigid distinction from singular terms to predicates follows.
Broadband plasmonic half-subtractor and digital demultiplexer in pure parallel connections
Authors: Wu Pei-Yuan , Chang Yun-Chorng , Huang Chen-Bin
Published: July 2022

Nanophotonic arithmetic circuits requiring cascaded Boolean operations are difficult to implement due to loss and footprint issues. In this work, we experimentally demonstrate plasmonic half-subtractor and demultiplexer circuits based on transmission-lines. Empowered by the unique polarization selectivity in the surface plasmon modal behaviors, both circuits are realized without cascading. The operations of the half-subtractor and demultiplexer can be performed using a single laser beam with three predefined linear polarizations. All of our experiments are performed using a 56 fs laser providing greater than 12.5 THz optical bandwidth. The experimental results are found in excellent quantitative accordance with numerical calculations. The photonic integrated circuit framework proposed in this work could pave the future avenue towards the realization of highly compact, multi-functional, on-chip integrated photonic processors.

Order-disorder (OD) structures of Rb2Zn(TeO3)(CO3)·H2O and Na2Zn2Te4O11
Authors: Eder Felix , Stöger Berthold , Weil Matthias
Published: July 2022

Single crystals of the two alkali metal zinc oxidotellurates(IV), Rb2Zn(TeO3)(CO3)·H2O and Na2Zn2Te4O11, were obtained by reactions of mixtures of ZnO, TeO2, Rb2CO3 (molar ratios 2:3:6) and ZnO, TeO2, Na2CO3 (molar ratios 2:3:10), respectively, with small amounts of water as a mineralizer. Both compounds crystallize as order-disorder (OD) structures of layers and feature a high stacking fault probability. The crystal structure of Rb2Zn(TeO3)(CO3)·H2O is composed of layers extending parallel to (100). The structure is composed of two kinds of non-polar OD layers consisting of trigonal-pyramidal [TeO3]2−, tetrahedral [ZnO4]6−, Rb1+, and CO3
2−, H2O, Rb2+, respectively. Different centrings of the layer groups lead to an ambiguity in the stacking arrangement. The crystal structure of Na2Zn2Te4O11 is built from layers extending parallel to (001). Trigonal-pyramidal [TeO3]2− and bisphenoidal [TeO4]4− polyhedra form [Te4O11]6− groups, which are connected by longer Te–O-contacts to form 1
∞[Te8O22]12− double chains oriented along either [100] or [010]. These chains form non-polar layers, which appear alternatingly in two orientations related by a fourfold rotoinversion. The Zn2+ and Na+ cations are located at the layer interface. The stacking ambiguity is due to different lattices of adjacent layers.

Published: July 2022

Este trabalho experimental objetivou o estudo da resistência de concretos de cimento Portland com ou sem fibras de aço de diferentes fatores de forma. Avaliaram-se a resistência à compressão, módulo de elasticidade longitudinal e resistência à tração na flexão. O programa experimental desenvolvido englobou dois tipos de concretos (resistência média e alta à compressão fcm = 35 Mpa e 70 MPa), sem ou com fibras de aço (teor em volume de 1% do volume do concreto e três tipos de fatores de forma – FF: 50, 67 e 80), perfazendo um total de 32 corpos-de-prova cilíndricos 150 mm x 300 mm e 24 corpos-de-prova prismáticos 150 mm x 150 mm x 500 mm, sendo 24 dos cilíndricos e 18 dos prismáticos com fibras de aço. Concluiu-se que a adição de fibras de aço nos concretos, em geral, melhorou as propriedades de resistência em relação às dos concretos sem fibras, além de aumentar suas ductilidade e tenacidade.
COMPARAÇÃO ENTRE O MÉTODO DA LARGURA EFETIVA E O MÉTODO DA RESISTÊNCIA DIRETA NO DIMENSIONAMENTO DE PERFIS CARTOLA FORMADOS A FRIO SUBMETIDOS À COMPRESSÃO
Authors: Filho Daniel Carlos Santos , Araujo Ricardo Rodrigues de
Published: July 2022

Este trabalho trata do dimensionamento de perfis de seção cartola através do Método da Largura Efetiva e do Método da Resistência Direta, ambos presentes na Norma Brasileira ABNT NBR 14762:2010,  visando comparar os valores encontrados. O programa GBTUL, baseado na Teoria Generalizada de Vigas (GBT), foi utilizado para determinar as cargas críticas de flambagem elástica. Observou-se a equiparação entre os valores determinados pelos dois métodos quando a carga axial de flambagem global elástica utilizada no MRD era determinada pelas prescrições da ABNT NBR 14762:2010. Nos casos em que os valores da carga global foram extraídos do GBTUL, os resultados se mostraram muito irregulares comparados com os do MLE. Constatou-se também que as propriedades geométricas calculadas pelo GBTUL para os perfis estudados apresentaram discrepâncias significativas em relação às apresentadas na ABNT NBR 6355:2012, podendo este ser o motivo da incoerência das cargas de flambagem global elástica fornecidas pelo GBTUL.

Hepatitis C virus mRNA contains an internal ribosome entry site (IRES) that mediates end‐independent translation initiation, requiring a subset of eukaryotic initiation factors (eIFs). Biochemical studies revealed that direct binding of the IRES to the 40S ribosomal subunit places the initiation codon into the P site, where it base pairs with eIF2‐bound Met‐tRNAiMet forming a 48S initiation complex. Subsequently, eIF5 and eIF5B mediate subunit joining, yielding an elongation‐competent 80S ribosome. Initiation can also proceed without eIF2, in which case Met‐tRNAiMet is recruited directly by eIF5B. However, the structures of initiation complexes assembled on the HCV IRES, the transitions between different states, and the accompanying conformational changes have remained unknown. To fill these gaps, we now obtained cryo‐EM structures of IRES initiation complexes, at resolutions up to 3.5 Å, that cover all major stages from the initial ribosomal association, through eIF2‐containing 48S initiation complexes, to eIF5B‐containing complexes immediately prior to subunit joining. These structures provide insights into the dynamic network of 40S/IRES contacts, highlight the role of IRES domain II, and reveal conformational changes that occur during the transition from eIF2‐ to eIF5B‐containing 48S complexes and prepare them for subunit joining.

There have been many developments in seed vigour research and vigour testing since 2001 when seed vigour was first introduced into the ISTA Rules. This article will describe the seed ageing / repair hypothesis which has formed the basis of new vigour tests, how the hypothesis can explain
differences in vigour and its use in vigour tests. The development and modification of ISTA validated vigour tests, and the extensive research that has examined the application of these tests to other species are described. Other approaches to vigour testing, based on seed response to stress,
respiratory indices of vigour and the cell cycle are described and evaluated. The current and potential use of advanced technologies, such as image analysis, in vigour testing, and molecular research based on proteome analysis and DNA repair in Arabidopsis thaliana are described. The
radicle emergence test, possibly using image analysis, is highlighted as having great potential for future application to a wide range of species. New approaches to vigour testing may be based on new technologies and molecular markers, but the need for rigorous evaluation of these approaches
using commercial seed lots of crop species is emphasised.

Pemanfaatan sumber energi terbarukan dalam bentuk sistem pembangkit hybrid saat ini menjadi salah satu upaya yang dapat dilakukan untuk mengurangi penggunaan bahan bakar fosil. Sistem interaktif grid yang memanfaatkan photovoltaic array dan diesel generator sebagai sumber energi dapat diaplikasikan di Indonesia dimana saat ini masih mengandalkan sumber energi fosil. Perangkat lunak yang digunakan dalam pemodelan sistem ini yaitu software Electric Transient and Analysis Program (ETAP). Tujuan dari pemodelan sistem ini yaitu mempermudah analisa sistem pembangkit hybrid photovoltaic (PV) dan diesel generator agar performanya sesuai dengan yang diinginkan. Pemodelan dan simulasi tersebut dapat digunakan sebagai alat bantu dalam merancang, membangun dan menganalisis sistem pembangkit energi hybrid photovoltaic (PV) dan diesel generator. Sistem interaktif grid ini merupakan penggabungan antara photovoltaic array, diesel generator dan juga jaringan listrik PLN. Tegangan keluaran dari photovoltaic (PV) diubah dari DC menjadi AC dengan menggunakan inverter. Ketika photovoltaic (PV) belum bisa menyuplai beban sebepenuhnya maka jaringan listrik PLN dan diesel generator masuk untuk membantu menyuplai beban. Desain sistem hybrid dengan memanfaatkan sumber energi matahari dapat dijadikan opsi yang lebih baik dari sistem sebelumnya.

The aim of this paper is to solve the problem of practical major training for biology majors under the framework of higher education modernization. By using a variety of specialized techniques, forms and teaching methods, a discipline that is not only universal and specialized has been formed, competencies, as well as reflective and professional self-actualization. The aim of this research is to study the practically test the organizational and pedagogical conditions of the practice-oriented training for the future teachers-biologists. This quantitative research is to study the practice-oriented training of student biologist from the literature review. Questionnaire pertaining to the scientific and methodological basis of practice-oriented were send to the 3rd and 4th year students majoring in biology. According to the framework standard, a descriptive analysis of the results is carried out on the respondents' assessment of the professional maturity of future teachers; motivation is a symbolic bundle of professional action motivation (professional orientation, job satisfaction), and the individual is an important characteristic of teachers forming an individual. Willingness, ways of personal self-expression and self-development (professional intent, reflection), and cognition serve as the basis for training subjects, methods, psychology, and teaching skills (vocational training, teaching thinking). The proposed levels of professional readiness of future teachers will help to improve the competency in pedagogy of the biology teacher and contribute to the higher education in term of the education curriculums.

Published: July 2022

During the pandemic of COVID-19, online learning was introduced, and the students' achievement decreased. This research aimed to find the effect of the biology learning model by using real objects (RO), ICT, and Blended Learning (BL) on students’ factual and conceptual knowledge. The research design was a quasi-experiment with a pretest and posttest comparison group design. This research was done in two senior high schools. Cluster random sampling was used to choose three groups of RO, ICT, and BL, involving two biology teachers and 139 students. The instrument was mainly tests of factual and conceptual knowledge. The test items were validated by expert judgment and an empirical test. Multivariate analysis was applied to test the difference in the effect of the three learning models. The results indicate that (1) RO gives the highest students’ achievement in factual knowledge, (2) ICT increases students’ conceptual knowledge, and (3) BL improves both factual and conceptual knowledge. Therefore, it is concluded that learning biology should use RO and ICT through BL to improve factual and conceptual knowledge.

Ordinary and advanced level physics teachers have similar responsibilities in impacting the knowledge of physics among learners. These responsibilities are premised around qualification, experience and job placement. Teachers’ experience has a place in the literature to influence physics performance. The curriculum of both advanced and ordinary level physics is with similarities and occasioned differences with respect to content knowledge. However, are there differences in the qualification, experience and job placement between these two sets of teachers? In view of the foregoing, this study examined advanced and ordinary level in-field physics teachers distribution vis a vis qualification, experience and job placement with a view to aggregate data for decision making, as well as, report gender representation, establish drift and possible remediation in the field. Descriptive research of the survey type was employed with Physics Teachers Ordinary and Advanced Level Inventory (PTOALI) as the instrument to elicit data from 225 physics teachers across the three states under review. Similarities exist in teachers’ qualification at ordinary and advance levels. Experience of teachers at ordinary level were higher than those teaching advanced level curriculum. Underrepresentation of female physics teachers was found among the sample audience. Also, physics teachers are limited in number across the sampled schools and that female physics teachers are under-represented within the sampled respondents. This study concludes that more qualified physics teachers are needed across the three states under review. Experienced physics teachers are also required in advanced level schools. This study recommends training and recruitment of adequate number of qualified physics teachers to cope with the surging number of willing learners.
