Published: September 2021

Os saguis-de-tufos-brancos (Callithrix jacchus) são primatas de pequeno porte que se adaptam bem à vida em cativeiro. Muitos são capturados pelos traficantes de animais silvestres e alguns morrem em função dos maus tratos e, quando apreendidos pelos agentes do IBAMA, precisam de cuidados veterinários. O objetivo do trabalho foi estudar a anatomia topográfica da cavidade abdominal de 10 cadáveres de saguis-de-tufos-brancos doados pelo CETAS/PB. Foram determinadas linhas de demarcação das regiões topográficas do abdome, sendo duas longitudinais que cruzam o ponto médio das clavículas e duas transversais, uma cranial entre os arcos costais e outra caudal entre as tuberosidades coxais. A disposição topográfica dos órgãos abdominais do sagui é semelhante à disposição observada em cães e gatos, especialmente nas regiões abdominais cranial e média. No entanto, no que se refere à localização do ceco, ele se estende por todo o flanco direito do sagui. Especificamente quanto à localização do cólon, o sagui se assemelha à espécie humana. Quanto à anatomia topográfica aplicada, verifica-se que é possível palpar, percutir e puncionar o fígado do sagui nas regiões hipocondríaca direita e xifoidea. Propõe-se como ponto de cecocentese o flanco direito. Este trabalho é importante para subsidiar os médicos veterinários na realização de procedimentos clínicos, cirúrgicos e exames de imagem.

Authors: TOKATLI Seda Gözde
Published: September 2021

Soğuk Savaş sonrası dönemde ABD’nin realist kuramın ilkeleri doğrultusunda aldığı kararlar pozitivist geleneğe dönüş vurgusu yaparken, Çin’in uluslararası sistem içerisinde yürüttüğü akıllı güç politikaları post-pozitivist geleneği ön plana çıkarmaktadır. Soğuk Savaş sonrası dönemde iki kutuplu dünya düzeninin sona ermesi sonucunda Amerikan yönetimi belirli bir süre sistem içerisindeki üstünlüğünü devam ettirse de 9/11 terör olayları sonucunda yaşanan siyasi kriz ve 2008 küresel mali kriz sonucunda sistem içerisindeki hegemonyası daha yüksek sesle sorgulanmaya başlanmıştır. Amerika’nın sistem içerisindeki gerileyişi rakip güç olan Çin’in ikame güç olabileceği yönündeki söylemleri arttırmıştır. Çin’in 2000’li yıllardan itibaren süreklilik gösteren yükselişi, sistem içerisinde daha belirgin rol oynamasına yol açmıştır. Bu çalışma da, uluslararası ilişkilerde hegemonya olgusu ele alınarak, uluslararası sistem içerisinde gücün dönüşümü Realist ve Neo- Gramsiyan hegemonya kavramı çerçevesinde ABD ve Çin rekabeti temellinde incelenecektir. Çalışmanın ana sorunu olan Çin’in artan ekonomik ve sosyo politik gücünün sistem üzerinde dönüşüm etkisi yaratacağı argümanını Neo-Gramsiyan hegemonyaya kavramı çerçevede analiz etmektedir.

Authors: Sanaei Masumeh , Kavoosi Fraidoon , Moezzi Mohammad Amin
Published: September 2021

Backgrounds: Epigenetic regulation such as DNA methylation plays a major role in chromatin organization and gene transcription. Additionally, histone modification is an epigenetic regulator of chromatin structure and influences chromatin organization and gene expression. The relationship between DNA methyltransferase (DNMTs) expression and promoter methylation of the tumor suppressor genes (TSGs) has been reported in various cancers. Previously, the effect of 5-aza-2'-deoxycytidine (5-AZA-CdR), trichostatin A (TSA), and valproic acid (VPA) was shown on various cancers. This study aimed to investigate the effect of 5'-fluoro-2'-deoxycytidine (FdCyd) and sodium butyrate on the genes of the intrinsic apoptotic pathway, p21, p53, cell viability, and apoptosis in human hepatocellular carcinoma SNU449, SNU475, and SNU368 cell lines.
Materials and Methods: In this lab trial study, the SNU449, SNU475, and SNU368 cells were cultured and treated with 5'-fluoro-2'-deoxycytidine and sodium butyrate. To determine cell viability, cell apoptosis, and the relative gene expression level, MTT assay, flow cytometry assay, and qRT-PCR were done respectively.
Results: 5'-fluoro-2'-deoxycytidine and sodium butyrate changed the expression level of the BAX, BAK, APAF1, Bcl-2, Bcl-xL, p21, and p53 gene (P<0.0001) by which induced cell apoptosis and inhibit cell growth in all three cell lines, SNU449, SNU475, and SNU368. 
Conclusion: Both compounds played their roles through the intrinsic apoptotic pathway to induce cell apoptosis.

Published: September 2021

Background: Frequent blood transfusion can lead to iron overload which is potentially dangerous for the heart and liver. Silymarin has well-documented protective effects on hepatocytes. The purpose of this study was to evaluate the hepatoprotective effects of silymarin addition to iron chelators in children with thalassemia.
Materials and Methods: This randomized, double-blinded, and placebo-controlled trial was performed on 40 subjects with thalassemia major and intermedia in Amir Kabir Hospital, Arak, Iran. Subjects were randomized 1:1 oral to 30 mg/kg deferasirox plus placebo, or deferasirox plus oral 70-140 mg silymarin (twice daily) for 6 months. Cardiac and hepatic iron levels and levels of Gamma-glutamyltransferase (GGT), Alanine transaminase (ALT), Aspartate transaminase (AST), Alkaline phosphatase (ALP), total bilirubin, albumin, total protein, and total cholesterol were measured at baseline and after 6 months of treatment.
Results: The mean age of patients was 16 years and 60% of patients were female. After 6 months, there were significant increases in the levels of ALT, AST, GGT, and TG in the placebo group as compared to the silymarin group (P < 0.05). In contrast, ALT, AST, and GGT had significant reductions compared to the silymarin group (P =0.05). Patients in the placebo group had a rise in total bilirubin (P = 0.07), but total protein and albumin did not have significant changes in the silymarin group (P > 0.05). Finally, a significant improvement was noted in cardiac iron values in patients using silymarin; 22.2 ± 6.6 ms at baseline vs 26.9 ± 7.1 ms at 6 months (P < 0.05).
Conclusion: This study suggests that twice-daily addition of silymarin to deferasirox could improve liver function in children with thalassemia major and intermedia. Silymarin seems safe in pediatrics.

Introduction: Headache is a common problem with intense side effects on quality of life. Dental and maxillofacial problems, including dental infections and temporomandibular disorders may trigger the onset of headache or have direct impact on the intensity of headache. The purpose of this paper is assessment of oral health indexes in chronic headache patients and compare it with a healthy control group.
Material & Methods: Thirty chronic headache patients based on diagnosis by a neurologist were enrolled in our study and thirty healthy volunteers were recruited into the control group. Dental and periodontal examination were carried out in order to evaluate of the decayed, missing and filled teeth (DMFT) index, the assessment of community periodontal index of treatment needs (CPITN) index and determination of tooth wear status and oral health status. Statistical analysis was done using SPSS statistical package (version 20, IBM).
Results: Mean age, educational level, tooth brushing, using dental floss and DMFT index was not statistically different between chronic headache patients and control group. There was no statistically significant difference in CPITN index between cases and control group (p-value=0.538).
Conclusion: This study suggest that chronic headache patients have an acceptable oral hygiene which may be attribute to their attempts to omit pain from head and oral region. Considering high prevalence of chronic headache, planning a protocol for oral hygiene instruction is necessary. In this regard, coordination between neurologists and oral medicine specialists can be very effective.

The chancing climate affects all humans and to reduce serious dangers for our and the next generations greenhouse gas emissions must be dramatically reduced in the next years. In this paper, the EU climate goals are introduced and measures are outlined on how fluid power can contribute to the achievement of the targets. There is still a long way in all industries to go to achieve the goal of zero greenhouse gas emissions, but we need now to think and talk about consequences and challenges for fluid power community.
Ionic liquids – the path to the first industrial application
Authors: Lovrec Darko
Published: September 2021

When using hydraulic fluids, users rarely ask themselves how the development of the hydraulic fluid they use in their hydraulic device has gone. Perhaps only curious users want to know the approximate composition of the newer, better hydraulic fluid, compared to the fluid of the previous generation. Rarely, however, do they know the developmental pathway of the new fluid. Even in the case of minor changes in the chemical composition of the fluid, e. g. a newer package of additives for mineral oils, or other base oil, requires lengthy fluid testing. First, in the manufacturer's laboratories, and then in the industrial environment. In the case of a completely new type of hydraulic fluid, the development path is much longer. The paper presents the behind-the-scenes development of a completely new type of hydraulic fluid - ionic liquid, from learning about the liquid itself all the way to industrial application.
Electrically tuneable viscosity of Ionic Liquids
Authors: Tič Vito
Published: September 2021

Viscosity is an essential property of lubricant, as it affects its capacity to form the lubricating film or to reduce friction and wear. One of highly desirable effect in tribology is to be able to control the viscosity of the lubricant externally in real-time without changing the lubricant. One of the possibilities is to apply an electric field to the lubricant. Since ionic liquids are solvent-free electrolytes, their properties can be usually altered by applying voltage. This preliminary research results reveal that viscosity of tested ionic liquid can be tuned by means of applying DC voltage.

Authors: Hobbs Matthew G. , Tomažin Janez , Dufresne Peter T.
Published: September 2021

In the growing power demands, turbine users want to feel confident that their equipment is reliable, efficient, and delivering peak performance every day. Proper care and maintenance of turbine oils is critical to avoiding disruptive and potentially costly downtime, and can help extend oil and component life. The ISO 55001 Asset Management and EN 17485 Maintenance within Physical Asset Management: “Framework for improving the value of the physical assets through their whole life cycle” provides an opportunity for companies to review and improve asset owner and service provider relationships, improve performance and utilisation of assets, reduce operational risk arising from the various stages of asset management and reduce the cost of insurance and ensure regulatory compliance. With such an approach and the use of the best available technology, turbine oil is becoming an asset. This article focuses on turbine oils quality, their degradation, additives and, varnish removal.

Authors: Jankovič Denis , Novak Rok , Šimic Marko , Herakovič Niko
Published: September 2021

The development of smart hydraulic press that allows rapid adaptation to high-volume variant production is a major challenge. Besides tool management, setting the control parameters, which can be considered as a correct press cycle, is an important part to achieve agile production. This paper presents a new approach to automatically generate a hydraulic press cycle where the important data of the production plan is known, such as the data or setting of the forming tool and the data of the product. In this case, RFID tracking system is used to read the tool/product data, which is input data for the mathematical algorithm for calculating the characteristic points of the hydraulic press cycle. The characteristic points are sent to the local PLC and stored as a matrix. The Beckhoff TwinCat platform is used for process control. Finally, a simple bending process is shown as a use case for concept verification.
Research on the water hydraulic pressure relief valve
Authors: Majdič Franc
Published: September 2021

Water hydraulics is increasingly becoming a viable alternative to oil hydraulics due to its environmental sustainability. The leakage of water hydraulic components is one of the reasons why water hydraulics is not more widely used. One of the missing water hydraulic components is also the two- stage pressure relief valve. Various valve designs have been investigated. FEM and CFD analyses of the relief valve were performed. Some prototypes were made and tested in the pressure range of 50 to 200 bar at a maximum flow rate of 30 lpm. The functional characteristics of the valve were studied, and the influence of each component was determined. It was found that the manufacture of a two-stage water valve is technologically feasible with appropriate design adjustments.
Luchas en contra de todo sistema de dominación
Authors: Mojica Mendieta Francisco Javier
Published: September 2021

América Latina y el Caribe asisten en el 2021 a las luchas “en contra de todo sistema de dominación”. Esta expresión fue planteada por Elisa Loncon, lideresa Mapuche, el 4 de julio de 2021 luego de ser elegida como presidente de la Convención Constitucional en Chile para redactar una nueva carta magna, y con ella, erradicar la herencia de la dictadura de Augusto Pinochet de Chile. En la historia reciente, estas luchas se originaron, primero, por la rebelión estudiantil secundaria de los “Pingüinos” en octubre de 2019 pero que tiene como antecedente más de tres quinquenios y; luego, por otros movimientos sociales que desembocaron en un proceso para redactar una nueva constituyente. Esta expresión, a mi criterio, sintetiza la lucha histórica de los pueblos desde América Latina y el Caribe contra el racismo; el genocidio; la esclavitud; el patriarcado; el falocentrismo, el androcentrismo, el capitaloceno visto desde el enfoque de la ecología-mundo desigual (Moore 2013a, 2013b, 2020; Navarro y Machado, 2020) y; la colonialidad, del poder, del saber y de la naturaleza. Teóricamente, este editorial es planteado desde teoría crítica y metodológicamente, a través de la revisión bibliográfica y el diálogo con activistas sociales y académicos del continente que me permiten realizar un sucinto repaso por los conflictos medulares de unos cuantos países de la región. En estas páginas espero evidenciar diferentes formas de resistencia y creatividad para refundar y proponer alternativas frente al sistema mundo moderno colonial de larga data -más de 500 años.

SoTL and the Humanities
Authors: Michael Renee , Little Deandra , Donelli-Sallee Emily
Published: September 2021

In this article, we share themes and tensions experienced by humanities faculty undertaking a scholarship of teaching & learning (SoTL) project as part of a multi-campus, grant-funded initiative. Faculty participants in the project iteratively transformed a course to improve one or more aspects of their students’ learning over a three-year period and documented the process and results in a course portfolio. To support their individual and collaborative work, each of the four campuses had a local leader, and participants met regularly with campus teams, convening with the full group annually for cross-campus knowledge exchange and peer review. At the project conclusion campus leaders gathered participant reflections and discovered a pattern of tensions that included: disciplinary ways of knowing, ways to represent knowing, and ways of writing and sharing. These tensions are similar to those identified elsewhere and can be potential impediments to this work for some in the humanities. Explicitly addressing those potential tensions while helping faculty see how their own disciplinary approaches can help them investigate their course practices is a useful first step toward more contributions from humanities scholars.

Published: September 2021

Capstone experiences (CEs) serve a variety of purposes in higher education as opportunities to apply academic skills, explore post-graduate life and employment, and achieve a meaningful undergraduate event. This study investigated the purposes of CEs through a content analysis of institutional course syllabi/course outlines/module outlines and catalog/calendar descriptions at five institutions of higher education: a large public research university in Canada, a large public teaching university in the United Kingdom (UK), a college of a large public research university in the United States (US), and two medium-sized private liberal arts universities in the US. Using the CE purposes found in a review of scholarly literature as a research guide, the authors analyzed 84 institutional documents. CE purposes that appeared in the sample at lower percentages when compared with published studies included oral communication, a coherent academic experience, preparation for graduate school, preparation for life after college, and civic engagement/service learning. Implications for practice include the need for instructors and administrators to consider revising CE documents to better reflect the content and goals of the courses and to address the requirements of other audiences (e.g., program reviewers, accreditation evaluators). Moreover, the results of this study may assist educators in considering reasons for omitting explicit purposes from CE documents and/or justifying the inclusion of previously omitted purposes.

Citing is a political act. It is a practice that can work both sides of the same coin: it can give voice, and it can silence. Through this research, we call for those contributing to the scholarship of teaching and learning (SoTL) to attend to this duality explicitly and intentionally. In this multidisciplinary field, SoTL knowledge-producers bring the citation norms of their home disciplines, a habit that calls for interrogation and negotiation of the citation practices used in this shared space. The aim of our study was to gather data about how citation is practiced within the SoTL community: who we cite, how we cite, and what values, priorities, and politics are conveyed in these practices. We were also interested in whether any self-selected categories of identity (e.g., gender, career stage) related to self-described citation practices and priorities. Findings suggest several statistically significant relationships did emerge, which we identify as important avenues for further research and writing. We conclude with 10 principles of citation practices in SoTL.
Increase Engaged Student Learning Using Google Docs as a Discussion Platform
Authors: Morse Mary
Published: September 2021

Online discussion board activities have traditionally been a primary method of providing student-to-student interaction, especially in asynchronous online classes. This study examines the impact of an alternate online discussion tool on student participation in online discussion assignments. Three identical discussion assignments were examined over the course of two semesters. The first semester utilized the traditional Learning Management System (LMS) threaded discussion board. The second semester incorporated Google Docs as the discussion platform. Overall, students using Google Docs made 68 percent more posts per student than students using the traditional LMS discussion board. Students using Google Docs also demonstrated more engagement by sharing professional experiences and teaching strategies more often than those students using the traditional LMS discussion board. While the data are encouraging, limitations of this study encourage additional research in the areas of discussion platform, discussion group size, and group assignment methods.
Breaking the Binary

The need to make higher education curricula gender-inclusive is increasingly pressing as student cohorts diversify. We adopted a student-staff partnership approach to design, integrate, and evaluate a module that taught first-year science students the difference between biological sex, gender identity, gender expression, and sexual orientation in the context of genetics concepts at an Australian university. This module aimed to break the binary in misconceptions of both sex and gender, emphasising that both exist on separate spectra. Data triangulation was used to evaluate students’ attitudes towards the module and their learning of module concepts. Students’ attitudes were positive overall, and evaluation of students’ learning indicated that the majority of students understood and retained key concepts, while also identifying common misconceptions. Perhaps the most important finding was that students who identified as belonging to a minority group had significantly more positive attitudes towards the module than non-minority students. This finding supports previous research that has found inclusive curricula have greater benefit for students from minority backgrounds, indicating the importance of making such curriculum enhancements. Our results speak to both the co-creation process and students’ learning outcomes, providing valuable insights for practitioners both within science and beyond.
Gravitational-Magnetic-Electric Interaction in Controlling Relative Permittivity and Permeability
Authors: Zhu Yin
Published: September 2021

Appling the controlling relative permittivity and permeability in the equations for the gravitational-magnetic-electric field interaction, a very large variation of the gravitational acceleration of the Earth by electric/magnetic field could be arrived at. This conclusion may be supported by some of the experiments for the gravitational effect of superconductivity.
Adp-Ribosylation as Post-Translational Modification of Proteins: Use of Inhibitors in Cancer Control
Authors: Poltronieri Palmiro , Miwa Masanao , Masutani Mitsuko
Published: September 2021

Among post-translational modifications of proteins, ADP-ribosylation has been studied for over fifty years, assigning to this PTM a large set of functions, including DNA repair, transcription and cell signaling. This review presents an update on the function of a large set of enzyme writers, the readers that are recruited by the modified targets, and the erasers that reverse the modification to the original amino acid residue, removing the covalent bonds formed. In particular, the review provides details on the involvement of the enzymes performing MAR/PAR cycling in cancers. Of note, there is potential for application of the inhibitors developed for cancer also in the therapy of non-oncological diseases such as the protection against oxidative stress, suppression of inflammatory responses, and the treatment of neurodegenerative diseases. This field of studies is not concluded, since novel enzymes are being discovered at a rapid pace.

Immunity has become an important aspect of concern, as the spread of corona virus, is on the rise. The strategies to boost and modulate the immunity have therefore become need of the hour. The present study was carried out to evaluate the effect of Charak immunity Tablets (CIT) on innate and adaptive immune response in healthy individuals. It was a single-blind, randomized, placebo-controlled, exploratory study. After obtaining Ethics Committee permission, 36 healthy individuals of either sex aged 18-35 years with prior consent were recruited in the study. They were randomly divided into 2 groups to receive either CIT or Placebo in 2:1 ratio. Both the interventions were given in a dose of 1 tab (500 mg) twice daily. The assessment variables were vitals [temperature, pulse, and blood pressure], respiratory health [respiratory rate, oxygen saturation and peak expiratory flow rate], questionnaire based assessment of immune status, perceived stress and quality of life along with objective assessment of immunity [CD4+, CD8+ counts, Interferon gamma (IFN γ), Tumor necrosis factor alpha (TNF-α) and Interleukin 10 (IL-10)] as well as oxidative stress; [Malondialdehyde (MDA) and Glutathione peroxidase], which were assessed at fixed time points. Of 36 recruited participants, only 18 participants completed the study. CIT treated individuals showed a statistically significant improvement in respiratory health, quality of life, perceived stress and subjective immune status. There was a decrease in the levels of serum IFN γ on day 60 compared to baseline. TNF-α and IL-10, both estimated from supernatant of Peripheral Blood Mononuclear Cells (PBMCs) stimulated with lipopolysaccharide (LPS), showed a decrease and a significant increase respectively on day 60 compared to baseline in CIT group. Further, CIT significantly decreased MDA levels.The present study indicates that CIT is an effective and safe drug to boost immunity. However, our findings need to be confirmed in larger sample size using more specific immune parameters.

Special Issue on the Great East Japan Earthquake Disaster: Part VI – Thoughts About the Great Disaster Now That Ten Years Have Passed –
Authors: Takiguchi Katsuki , Hayashi Haruo
Published: September 2021

A holistic and comprehensive perspective on society is essential to disaster research. However, at one time, the world did not have any scholarly journals that dealt with disasters from a holistic point of view. This situation gave rise to the Journal of Disaster Research (JDR), the first issue of which was published in August 2006. In principle, six issues are published annually, with special or extra issues also published in some years.

The Great East Japan Earthquake struck in March 2011, five years after the first issue of the JDR. Following this incident, we decided to publish a special issue whenever there was a major disaster. All accepted papers and articles were to be published free of charge, in electronic format. So far, eight special issues have been published.

Since this year 2021 marks the tenth anniversary of that disaster, we at the JDR have decided to publish a special issue of notes on the Great East Japan Earthquake Disaster. The selected theme is “Thoughts About the Great Disaster Now That Ten Years Have Passed.” As an academic journal dealing comprehensively with disasters and disaster risk reduction, we asked people working in all disaster-related fields to submit, from their unique perspectives, their views or proposals in any area or subject regarding what changes have taken place, what has remained the same, or what is needed in the future.

We have the twelve notes presented here in this Special Issue on the Great East Japan Earthquake Disaster: Part VI. We hope that these notes provide seeds for further progress in the field of disaster research.

Lastly, the editors would like to thank all contributors who submitted their manuscripts and the reviewers who provided valuable feedback with their constructive comments.

While governmental agencies have provided wide-ranging support to help the public recover from the impact of the Great East Japan disaster, their efforts have not been all-encompassing. Meanwhile, non-profit organizations and foundations have played a crucial role in this aspect. This study highlights the significant characteristics of a foundation, “The MICHINOKU Future Fund,” which has provided financial support to children who lost their parent(s) in the 2011 disaster. The Fund is a compelling case in disaster giving. It has been receiving donations for ten years, even after the disaster, with a steady increase in contributions from corporations and individuals. Our study explores this extraordinary case and identifies factors leading to successful fundraising as they endeavor to rebuild the society in the aftermath of an untoward disaster. Given that around 70% of the donations that the Fund receives come from private firms, most of whom have donated multiple times, the study aims to understand why businesses continue to donate to the Fund. We conducted semi-structured interviews with 12 donating companies. From the analyses of transcribed interviews applying the grounded theory approach, we identified sustained donations from multiple aspects of the Fund that the companies found favorable, including the opportunity to provide continued support to children’s future and frequent reporting from dedicated staff members. The companies learned from the experience of disaster giving, and preferred to avoid providing one-shot support. This study contributes to the literature on disaster giving, particularly corporate donations in Japan, on which limited knowledge has been accumulated to date.
