Comparative root anatomy and root bud development in two species of Malvaceae
Authors: Santos Devid Lucas Tenório dos , Barbosa Lucas Henrique Santos , Ferro Luan Henrique da Silva , Lima Leomar da Silva de , Cury Graziela
Published: December 2024

Abstract Underground plant organs, usually the thickened ones, can be capable of producing buds that allow shoot regrowth when the aerial part of the plants is eliminated. Some plants have roots that produce buds, which may or may not be branched systems, but which allow vegetative propagation in unfavorable environments due the presence of carbohydrate reserves. This study aimed to analyze and compare the anatomy of the roots of two Brazilian species, Apeiba tibourbou and Pachira aquatica, that present starch grains, buds and the ability to propagate vegetatively. Material of both species was analyzed in loco, collected and compared through anatomical analysis using standardized methods. Tests for carbohydrate detection were also applied. Anatomical analyses showed that the roots produced endogenous buds, originating from pericycle cells in A. tibourbou and from parenchyma rays in P. aquatica. Both species presented starch as carbohydrate reserve. The results demonstrated not only the high potential of differentiation and specialization of plant cells, but also the diverse reproductive strategies adopted by these species of the family Malvaceae, whether they are associated with the environment or not.

Published: December 2024

Abstract Byttneria irwinii (Malvaceae, Byttnerioideae) is a species primarily restricted to Cerrado vegetations in Central Brazil, yet it remains poorly represented in herbarium collections. The first descriptions, derived solely from specimens originating from Nova Xavantina in the Eastern region of Mato Grosso state, Central-West Brazil, are supplemented by limited subsequent collections, predominantly from the same area. Our recent discovery of a specimen in an undocumented region for the species, at the south from the type locality, within Parque Nacional das Emas, Southwestern Goiás state, expands the known distribution of this species toward the southern reaches. This study presents an updated illustration depicting B. irwinii in its natural habitat, with a revised distribution map reflecting this expanded range. Furthermore, we conduct a preliminary conservation assessment, comparing standard geographic range metrics before and after including these newly collected specimens. Our findings underscore the imperative of ongoing field expeditions to validate and augment our comprehension of species with narrow distribution.

Published: December 2024

RESUMO O objetivo do estudo foi descrever a oferta, o trabalho e a educação permanente em torno das Práticas Integrativas e Complementares (PIC), na perspectiva dos profissionais de saúde. Trata-se de estudo transversal, com análise dos módulos I e II do 3º Ciclo do Programa Nacional de Melhoria do Acesso e da Qualidade da Atenção Básica. Identificaram-se o perfil dos 186 profissionais, dados sobre PIC, processo de trabalho e educação permanente. Desses, 88,7% ofertavam alguma prática, sendo os enfermeiros os que mais ofereciam (96,2%). A auriculoterapia (83,3%), o uso de plantas medicinais e fitoterápicos (77,9%) e a terapia comunitária (48,9%) foram as práticas mais ofertadas. 86,5% dos entrevistados relataram receber apoio gerencial, no entanto, observou-se escassez de insumos. 82,2% dos entrevistados participaram de momentos de educação permanente relacionados às práticas ofertados pela gestão municipal (93%), na própria unidade de saúde (90,8%). Observou-se que há um processo de educação permanente, no entanto, o principal entrave à consolidação desse modelo de cuidado na Atenção Primária à Saúde está relacionado à disponibilização de insumos. Dessa forma, necessita-se de incentivos para melhoria do processo de trabalho em saúde com vistas à ampliação e à qualificação da oferta das diferentes PIC.

A pesquisa foi materializada a partir de análise bibliográfica e documental, além do trabalho de campo, com a realização de 12 entrevistas. Relatos sobre estigmatização e sofrimento apareceram em todas as entrevistas. Esses jovens revelaram sentir forte angústia, desespero e medo. Os resultados do estudo permitiram a conclusão de que as experiências socializadoras dos jovens atingidos entrevistados estavam ocorrendo em um contexto de profunda afetação diante do desastre que marcou completamente suas vidas, sobretudo por seu caráter traumático e compulsório, agravado pela ausência de garantia de reparação justa e integral.
A conceptual framework for sociohistorical research at the intersection of disability and race in (art) education
Authors: Gabriel Jenna
Published: December 2024

In this paper, I present a conceptual framework for conducting sociohistorical research at the intersection of disability and race in (art) education. Drawing on Crawford (2020), I present an expansive framework that makes visible the relationships between the theory I employ in my scholarship, the literature on which I draw, the specific sociohistorical context of Richmond, VA -- the city in which I live and work -- and my own positioning as a white, disabled, Southern, anti-Zionist Jewish mother, organizer, teacher, and doctoral candidate. I begin by charting how this framework is both a heuristic used in the context of my dissertation study and a record of reflexive theorizing to understand my scholar-activist praxis at this particular moment in time. I then discuss the conceptual framework, with detailed exploration of the personal experiences, relevant literature, and theories that inform its utility. I conclude by offering thoughts on how the framework might be applied in future scholarship -- both my own and that of others. 
An Empirical Study on the Rise of Digital Nomad and Workcation Ecosystems: Focusing on the Case of Thailand
Authors:   The Tourism Sciences Society Of Korea, Choi Jung-min , Qu Jia-Qi
Published: December 2024

This study explores the emerging lifestyles and work patterns of digital nomads and “workation” (work + vacation) enthusiasts. By analyzing search trends from Google Trends and Naver DataLab, along with related book listings from major online bookstores in South Korea, this study assesses the growing public interest in these phenomena. Field investigations of coworking spaces and surveys with foreign users in Thailand provide insights into the micro-characteristics of digital nomad ecosystems. The findings reveal a surge in public interest in digital nomadism after the COVID-19 pandemic, which signals a paradigm shift in work and life in the post-pandemic era. Case studies in Chiang Mai and Bangkok highlight the crucial role of coworking spaces in fostering digital nomad communities and enhancing work productivity. Surveys uncover heterogeneity among digital nomads, with differences in work styles and lifestyles based on age and gender. However, the sustainability of digital nomadism as an alternative lifestyle requires addressing challenges at individual, social, and institutional levels. The study‘s significance lies in its timely exploration of an emerging topic, multi-level analysis, and evidence-based insights. Although the findings may have limited generalizability mainly due to the small and contextual samples, the study offers valuable contributions to academic discourse and policy discussions. Future studies should examine the long-term impacts of digital nomad lifestyles, conduct cross-national comparisons, and investigate strategies for developing nomad-friendly policies and infrastructure.
A szülők zenei biográfiája, művészeti tevékenysége és annak hatása gyermekük zenei tanulmányára

Published: December 2024

Children's artistic studies are most often based on a well-functioning team. At the heart of this are the children, who form a close unit with their teachers. However, parental support, encouragement and the cultural capital that provides children with values and experiences from an early age are not negligible factors. In this study, we investigated parents' musical biographies, their current artistic activities and habits, and their impact on their children. Our results confirm that parental education and occupation are determinants of cultural capital. Gender differences in relation to artistic activities can be seen, and there is a clear link between the impact of artistic activities in childhood and current occupations of this type, which spill over into children's activities.

Published: December 2024

In March 2020, the COVID19 pandemic led to a number of fundamental changes in all education systems. Following the lockdowns that aimed at limiting the spread of the virus, educational processes had to be re-thought globally. Countless institutions have started online-based distance education, in many cases despite the lack of the necessary infrastructure background and adequate preparation of teachers. At the time of the data collection of our research, in the spring of 2022, the distance learning form was only used in certain areas, e.g. in the part-time and evening courses of some higher education institutions. In all levels of public education, the previous in-person education has returned, including in the field of music education. Singing and the sound of instruments can be heard from music schools again, and for the outside observer, the old order has been re-stored. However, those who participated in online education must carry their good or not so good memories with them, Children carry on the knowledge they acquired or seemed to have, and teachers and parents mainly carry their experiences. Our previous investigation focused on music teachers and children, and our current research focuses on par-ents who are in the background, but are constantly present, providing reinforcement and help. The aim of our study is to analyse how the parents of children attending music school and playing instruments (N=458) felt about the movement of music education to online platforms, as well as their children’s motivation and academic efficiency. Based on our results, we concluded that the parents accepted and undertook the additional burdens associated with virtual education, and their children could continue their extracurricular studies in a supportive environment. Parents noticed a change in the effectiveness of education, but it was important to them that their children did not interrupt their music studies, so they supported them with their attention even when the chil-dren were less motivated.

Published: December 2024

2020 márciusa nem várt helyzet elé állította az oktatás valamennyi színterét, így a zenei nevelés területét is. A zenepedagógusok számára az óratartás és az ismeretek átadásának online környezetbe való implementálása jelentette a legnagyobb kihívást. A tanulók rugalmassága és alkalmazkodóképessége mellett a szülők segítő támogatása tette lehetővé a produktív együttműködést. Az otthontanulás tapasztalatainak megismerése az oktatás számára is új lehetőségeket nyitott. Mindezidáig a szülői oldal véleménye kevésbé nyert teret a tudományos kutatások terén, ezért jelen munkánk során az online zeneoktatás láthatatlan aktorainak benyomásait mértük fel. A kérdőív nyitott kérdéseire kapott válaszokat MAXQDA Analytics Pro kvalitatív adatelemző szoftver segítségével kvantifikáltuk. Eredményeink prezentálása során törekedtünk a zenetanári (Szalai, Mike & Radócz, 2022) és a szülői meglátások differenciáinak feltárására. Az online zeneoktatás előnyein és hátrányain túl bemutatásra kerültek a pre- és posztcovid időszak zenepedagógiai sajátosságai, továbbá azon szülők véleménye is, akik a pandémiás időszak alatt több zenét tanuló gyermeket is neveltek.
Az alapfokú zeneoktatás jellemzői virtuális térben a Covid-19 ideje alatt

Published: December 2024

The Doctoral Program on Educational Sciences of the University of Debrecen, the Faculty of Music and the Art Pedagogy Research Group of the Foundation for the Art of Future launched research in the fall of 2021, investigating the role of parents in children's musical education in both real and virtual space. The data collection took place in the spring of 2022 with the support of the Research Institute of Art Theory and Methodology of Hungarian Academy of Arts. The self-made measuring instrument, containing closed and open questions, focused on the opinions of parents whose children play an instrument in elementary art school or attend private singing lessons. The opinion of the respondents (N=458) can be interesting, as during this period they could see a little more into the teaching of music and see things from a different perspective. The survey also looked at parents' music listening habits and the factors that influence them. The results showed that those who had been involved in music more often attended concerts of light and classical music and listened to music not only in a contextual way but also for its own sake, while those who had never received music education tended to listen to music only as a back-up during other activities.
An innovative method and a medical screening device for cancer detection in real-time
Authors: K Papageorgiou , G Papageorgiou
Published: December 2024

Histopathology is the main technique to assess the presence of cancer cells in biopsy material and for the evaluation of positive resection margins, but it is not real-time. Older methods to assess resection margin intraoperatively are either time-consuming or exhibit a low accuracy. More recent imaging techniques have various drawbacks, like the need for exogenous contrast agents or excessive time to assess the entire resection surface or a low diagnostic performance in detecting certain types of cancer. The purpose of the current research work is the development of a medical screening device for cancer cells detection with very high accuracy and selectivity, based on a newly developed method in order to experimentally measure in real-time the excitation response of the charged elements of the biological tissue under study to the applied alternative electrical field, over a wide range of frequency spectra.
The aim of this study is to present an innovative method and results from a prototype medical screening device, which allows the selective and “real-time” detection of cancer cells of any type among normal cells in any tissue type.
The innovation of the proposed method lies in the view of the cell membrane emulation as an electrical circuit and also in the ability to experimentally measure in real-time the excitation response of the charged elements of the biological tissue under studies like ions, interfaces or dipoles to the applied alternative electrical field, over a wide range of frequency spectra according to the dielectric spectroscopy method. The ions can very easily follow the variations of the applied alternating electric field moving along the dynamic lines of the field. In contrast, the incapability of the abnormal neoplastic cellular formations to follow the frequency changes causes them to perform dipole oscillation instead of moving along the dynamic lines of the field. This experimentally appears as a significant increase of the capacitive component contribution to the total impedance of the tissue, relative to the purely electrical resistance contribution of the ions. A model, backed by the relevant mathematical equations, has been developed to integrate the unknown impedance of both the tissue under assessment and the interdigital micro-sensor with the known complex impedance of the data acquisition system. The ability to selectively detect cancer cells has an obvious interest and various applications in cancer diagnosis and therapy.
The Mind & Muscles: A Protocol for the simultaneous measuring of cognitive and muscular activation during stone tool tasks using surface Electromyography and Electroencephalography v1
Authors: Eteson Brienna , Alexandros Karakostis Fotios
Published: December 2024

This protocol presents the first detailed step-by-step pipeline for a combined methodology to record and pre-process data from surface electromyography (sEMG) and electroencephalography (EEG) simultaneously, in experiments focusing on the evolution of human manual behavior (e.g., stone tool use). This integrative approach enables monitoring both muscular and cognitive activation during specific stone tool tasks, allowing for accurate combined analysis of both functions to the millisecond. Data collection and preprocessing are conducted using BrainVision hardware and software (Brain Products GbmH, Gilching, Germany) [1,8]. BrainVision Recorder (version 1.24.0101) [1] captures the sEMG and EEG signals, while BrainVision Analyzer (version 2.2.1) [8] was utilized for cleaning and pre-processing the data. This protocol outlines an experiment monitoring participants during a simple and widely studied stone tool task: Oldowan flake cutting. This task uses replica Oldowan flakes, due to the tools' importance as one of the first sharp-edged tools within the hominin archaeological record. Participants are required to hold, aim, and then accurately cut pieces of faux leather using the stone tool, while their muscular and brain activation levels are recorded.

single-cell Micro-C protocol v2
Authors: Wu Honggui , Tan Longzhi
Published: December 2024

Here we present a single-cell 3D genome mapping assay with improved spatial resolution with the help of micrococcal nuclease (MNase), termed single-cell Micro-C (scMicro-C). To achieve scMicro-C, we made three improvements. First, we titrated MNase digestion to reduce DNA loss and produce proper DNA fragments. Second, we solubilized chromatin with an ionic detergent, sodium dodecyl sulfate (SDS), which dramatically improved ligation efficiency. Third, we adopted our high-coverage transposon-based whole-genome amplification method, META (19), using Tn5 (20), to enhance the detection of chromatin “contacts.” scMicro-C retains the high signal-to-noise and high-resolution characteristics of bulk Micro-C, as indicated the accurate detection chromatin loops and other fine-scale chromatin structures. Furthermore, scMicro-C retains nucleosome and other chromatin-bound proteins (e.g., transcription factor) occupancy information. With our previously developed Dip-C algorithm, we confirmed that scMicro-C enables the reproducible reconstruction of 3D genome structures in single-cell at 5 kb resolution. With such kilobase 3D structures, we were able to explore the fine-scale chromatin folding in individual cells.

Factors Influencing Malays as a Second Language Learning in Essay Writing: A case study of Iban Ethnic Students in Sarawak, Malaysia
Authors: Austrus Edmund , Mahamod Zamri , Adnan Norhafizah
Published: December 2024

Second language learners, such as Iban students studying Malay, often face significant challenges in essay writing due to the proficiency gap between their first language and Malay. The lack of daily use of Malay further complicates their ability to grasp complex sentence structures and vocabulary, making essay writing a particularly difficult task for non-native speakers. This study aims to identify the factors influencing the learning of Malay as a second language in essay writing among Iban ethnic students. The study employed a qualitative research approach, involving semi-structured interviews with eight primary school Malay language teachers in the Kapit district of Sarawak. The data were analysed thematically using Nvivo 12 software. The findings identified three main factors: (i) mother tongue factors influence, (ii) linguistic environment factors influence, and (iii) psychological factors influence. As a result, the process of second language acquisition in educational settings requires deliberate and structured approaches, rather than relying on the natural language development seen with a first language. This study offers useful perspectives for both researchers and educators to refine teaching methods, focusing on more targeted strategies that can better support Iban students in improving their proficiency in Malay as a second language.
Radio Malaysia in 1978: Broadcasting Nationalist and Patriotic Ideas in Primary Schools Through Songs
Authors: Yan Chai Ming , Amir Hamzah Shazlin
Published: December 2024

Patriotic songs serve as symbols and catalysts of national identity. These songs, ranging from the national anthem "Negaraku" to a diverse repertoire of unofficial anthems, have played a crucial role in shaping the nation's cultural landscape and fostering a sense of unity among its diverse population. The popularity of these patriotic songs can be traced back to the nation's independence in 1957, when citizens had to learn the newly composed national anthem. The newly formed nation would require symbols that function as a catalyst for the realisation of Malaysia. The introduction of radio music education in Malaysian public schools in 1946 marked a significant milestone, as it allowed for the systemic dissemination of patriotic songs through the Radio Pendidikan (Radio Education) program. This program broadcasted songs to primary school students, exposing the younger generation to expressions of nationalism and patriotism through song. Through a thematic content analysis of the songs featured in the Radio Pendidikan 1978 program, the objective of this article aims to explore how the underlying themes of nationalism and patriotism were reflected in these musical compositions. The findings contribute to the understanding of the intersection between music, education, and nation-building; implicating the powerful influence of patriotic songs in uniting a diverse population and fostering a strong sense of national pride.

Published: December 2024

Indigenous languages serve as vital communication systems, influencing actions in various contexts. In South Africa, with 12 official languages, marketers must strategically select the language that resonates with their target audience. Research has highlighted the impact of English's dominance on indigenous languages, particularly in radio advertising, and how brand managers in multilingual settings utilise code-switching for effective communication. However, there is a gap in understanding indigenous language speakers' views on their languages' usage in radio commercials. This study focused on MTN subscribers' perceptions of the use of Setswana in radio advertisements and the challenges they face while listening to them. Employing perception theory, the research utilised a mixed-method approach, distributing 216 questionnaires to MTN subscribers in Mahikeng and conducting focus group discussions with 24 participants. The study aimed to assess Setswana's perceptions in radio ads and identify associated challenges. Findings showed that familiarity with a language fosters brand trust and credibility, ultimately enhancing economic performance in multilingual countries like South Africa. The study revealed key challenges, such as a lack of skilled voice actors fluent in Setswana and the rapid pace of indigenous language radio commercials, which impede comprehension. According to the study’s findings, we advocate for increased use of indigenous languages in radio commercials to better connect with diverse audiences and improve brand engagement.

Published: December 2024

The prevalence of defective vehicles, or “lemons,” in the Malaysian automotive market continues to raise concerns despite the existence of consumer protection laws. This study aims to investigate the efficacy of Malaysia’s consumer protection laws in addressing this persistent issue and examine the potential impact of adopting Lemon Laws in Malaysia. Employing a doctrinal methodology, the study examines statutes, case laws, and scholarly literatures to offer a detailed understanding of the current legal landscape and the mechanics of Lemon Laws in selected jurisdictions. The research undertakes a comprehensive analysis of relevant legislation, including but not limited to the Malaysian Consumer Protection Act 1999 to identify potential limitations and areas for improvement. It further explores the concept of “Lemon Laws,” successfully implemented in various jurisdictions, and assesses their potential applicability within the Malaysian context. The research findings advocate for the strategic amendment of the existing Consumer Protection Act 1999 to incorporate provisions analogous to Lemon Laws, thereby strengthening consumer rights and nurturing a more equitable and transparent automotive marketplace in Malaysia.

Published: December 2024

Arus pemodenan dan kepesatan teknologi hari ini menyaksikan lahirnya generasi yang banyak bergantung pada teknologi maklumat dan komunikasi. Kesannya pelbagai pengaruh dalam dan luar negara mampu mempengaruhi mereka dalam segenap aspek. Iman yang teguh dan jati diri kukuh menjadi benteng utama. Kajian ini ingin mengkaji tentang penerimaan dan penghayatan generasi hari ini terhadap unsur tradisi dalam Perlembagaan Persekutuan menurut perspektif pakar. Kaedah metodologi kajian menggunakan pendekatan kualitatif, iaitu temubual dilakukan terhadap enam orang pakar. Pakar dipilih dari bidang sosiologi perlembagaan, undang-undang, sejarah dan pembinaan bangsa. Hasil temubual dapat dilihat dari segi penggunaan bahasa Melayu yang agak sederhana, jurang antara kelas sosial iaitu kelas elit lebih mempunyai banyak peluang berbanding orang biasa, sekolah yang menghimpunkan semua etnik mampu mewujudkan perpaduan antara kaum, penghayatan generasi sekarang terhadap unsur tradisi kurang berbanding generasi dahulu, diskriminasi positif, perpaduan masyarakat Malaysia, unsur tradisi dikekalkan dan keharmonian antara kaum di Malaysia. Hasil dapatan ini juga mendedahkan bahawa pada pandangan pakar generasi hari ini menerima unsur tradisi dalam Perlembagaan Persekutuan, tetapi dari segi penghayatan agak kurang. Ini dikaitkan dengan penggunaan bahasa Melayu, isu-isu agama yang dimainkan, penghayatan agama dan ketidakpuasan hati terhadap kedudukan orang Melayu dan bumiputera. Implikasi daripada kajian ini, pendedahan dan pemahaman masyarakat tentang elemen unsur tradisi ini perlu diperkasakan lagi dalam kalangan generasi muda agar penghayatan mereka dapat ditingkatkan.

Data includes articles published between 2019 and 2024, with strict inclusion criteria to ensure relevance to disaster mitigation in Sulawesi. Research findings show that the four main types of disasters are floods, landslides, volcanic eruptions and tsunamis. disaster mitigation in Sulawesi. In addition, there is a lack of knowledge and implementation of sustainable mitigation strategies, as well as the need for active involvement of local communities in mitigation programs. The implications of this research emphasize the importance of evaluating existing disaster mitigation programs and more effective development policies, which can increase community preparedness and resilience to disasters. It is hoped that this research can make a significant contribution to efforts to reduce disaster risk in the region, as well as encourage collaboration between government, institutions and society in improving disaster mitigation.
Bisexual Identity Concealment for Marital Harmony: Cultural and Religious Pressures in Malaysia
Authors: Dalin Mohd Rafizey , Yusoff Nur Hafizah , Abdullah Azlina
Published: December 2024

This study investigates the concealment of bisexual identity among married men in Malaysia, a country where homosexuality is both stigmatized and criminalized under Syariah law. The problem lies in the immense cultural, religious, and legal pressures that compel these men to hide their sexual orientation, leading to significant emotional and psychological challenges. The primary objective of this research is to explore how these men manage their bisexual identities while maintaining marital harmony within a conservative, heteronormative society. Using a qualitative phenomenological approach, in-depth interviews were conducted with 15 self-identified bisexual men married to heterosexual women. The data were analyzed through thematic analysis. The findings reveal that societal expectations, fear of divorce, and family reputation are key factors influencing their decision to hide their sexual orientation. Participants reported high levels of anxiety, guilt, and isolation due to the dual pressure of performing heteronormativity in public while concealing their true selves in private. This study contributes to understanding the challenges faced by bisexual men in mixed-orientation marriages in Malaysia, particularly the psychological toll of maintaining secrecy. The implications underscore the need for culturally sensitive mental health services and policy reforms to provide adequate support for bisexual individuals. Such interventions are critical to reducing stigma and promoting emotional well-being in conservative societies.

Bu çalışmada polipropilen/montmorillonit (PP/MMT) polimer/seramik kompozitinden farklı oranlarda kimyasal köpürtme ajanı kullanarak plastik ekstrüzyon yöntemiyle üretilen polimer esaslı köpüklerin özellikleri incelenmiştir. Köpük üretiminin ilk adımında kompoziti oluşturan bileşenler, ekstrüzyon makinesinde homojen bir karışım elde etmek için eriyik olarak karıştırılmıştır. İkinci aşamada PP/MMT karışımına ağırlıkça (ağ.) %3, 6, 9 oranlarında ITP 825 ticari isimli kimyasal köpürtücü ajan (KKA) eklenerek ekstrüde edildikten sonra köpük formunda kompozit granüller elde edilmiştir. Nemi uzaklaştırmak için kurutma işlemine tabi tutulan köpük granüller, plastik enjeksiyon makinesinde test numune standartlarına uygun olarak kalıplanmıştır. Polimer esaslı köpüklerin fiziksel özelliklerini incelemek için; aşınma, partikül boyut analizi, termal özelliklerini incelemek için; ısıl çarpılma sıcaklığı (HDT), vicat yumuşama sıcaklığı, erime akış indeksi (MFI) ve mikro yapısını incelemek için; taramalı elektron mikroskobisi (SEM) testleri yapılmıştır. Kil ilavesinin polimerin termal direncini artırdığı görülmüştür fakat gözenek artışı ile termal özellikler olumsuz etkilenmiştir. Ağ. %5 MMT ilavesiyle polimer/seramik kompozitlerin HDT ve Vicat değerleri sırasıyle %3,8 ve %1,4 oranında artış göstermiştir.

Macroalgae are important bioorganisms used in fish feed and food industry. In addition, macroalgae are used in studies to determine radioactive pollution levels in the seas. In this study, it was aimed to determine the activity concentrations of 226Ra, 232Th, 137Cs and 40K in Cystoseira barbata which is a brown macroalgae samples obtained from the Eastern Black Sea coast of Turkey. Gamma spectrometry analyzes of the samples were carried out with high purity germanium (HPGe) detector system in the Nuclear Physics laboratory of Recep Tayyip Erdoğan University. The average 226Ra, 232Th, 137Cs and 40K activity concentrations in the samples were found to be 11.2, 7.61, 2.74 and 690.7 Bq.kg-1, respectively. The average annual effective dose values resulting from these radionuclides were obtained as 3.14, 1.75, 0.04 and 4.28 µSv.y-1, respectively. Total annual effective dose values calculated with the contribution of all radionuclides were found to be in the range of 1.37-18.83 µSv.y-1. The calculated annual effective dose values are lower than 0.29 mSv.y-1, which is stated by UNSCEAR as the average annual effective dose received through ingestion of natural radionuclides, and the samples examined do not pose any radiological risk.

Bu amaçla ilk aşamada sayısal arazi modelinin kurulması amacıyla LİDAR entegre insansız hava araçları ile uçuşlar yapılmış, elde edilen fotogrametrik veriler kullanılarak çalışma konusu kaya şevlerine ait sayısal arazi modeli hazırlanmıştır. Çalışmada süreksizlik ölçümlerinden elde edilen veriler ve daha önce düşerek şev tabanlarında biriken bloklar dikkate alınarak 3 boyutlu analizlerde kaynak olarak kullanılacak blok boyutları ve şekilleri belirlenmiş, literatür verileri dikkate alınarak normal geri verme katsayısı 0.75, tanjant geri verme katsayısı 0.75, sürtünme katsayısı 0.4 olarak kabul edilmiştir. Yapılan 3 boyutlu kaya düşme analizlerinde blok enerjisi, sıçrama yüksekliği, hareket eden blokların durduğu noktalar ve blok hızı değerleri hesaplanmış ve bu değerlere ait 3 boyutlu görseller hazırlanmıştır Analiz sonuçları blok hızı değerlerinin ortalama 15 m/s olduğunu, blok enerjilerinin maksimum değerlerinin farklı alanlarda 50-200 kJ arasında değiştiğini göstermektedir. 3 boyutlu kaya düşme analiz sonuçları, şevlerin konumu ve yüksekliği, şevler ile karayolu arasındaki tampon bölgelerin genişliği gibi özellikler bir bütün olarak değerlendirilerek blok enerji değeri 100 kJ’dan küçük olan alanlarda yamaç temizliği sonrası “güçlendirilmiş çelik ağ”, blok enerji değeri 100 kJ’dan yüksek olan alanlarda “güçlendirilmiş çelik ağ” üzerinde “yüksek kapasiteli halka ağ” kullanarak şevlerin sarılması önerilmiştir.
Determination of biodegradation performance for fabricated by MEW Chitosan/PCL composite stents with in vitro tests
Authors: Bozkurt Yusuf Burak
Published: December 2024

Today, biodegradable implants have begun to become a serious alternative to permanent implant groups. Especially the development of polymer material technology can be an alternative to metallic medical instruments. An innovative manufacturing method for the fabricated of these polymeric implants is melt electrowriting (MEW). This innovative method, which emerged as a result of studies on the production quality of additive manufacturing technology, is used in products with smaller and more complex geometries, such as stents. It is anticipated that this method, which is particularly convenient for patient-specific implant models, will have an important place in the implant production market in the future. Within the framework of this perspective, in this study, a study was conducted on the polycarbolactone group using the MEW method. In order to improve the biodegradability character, biodegradability experiments of chitosan-doped stents were conducted in vitro. The degradation character of the samples subjected to immersion corrosion in two different media for 1, 7, 14 and 21 days was examined based on residual mass. It has been determined that chitosan reinforcement has a buffering effect and plays a retarding role on the degradation time.

Estranheza e vertigem na literatura latino-americana contemporânea: pensar as ilhas contemporâneas em La Villa e Opisanie Swiata
Authors: França Bárbara Xavier
Published: December 2024

O trabalho discute a construção e as relações estabelecidas pelo espaço da “villa miseria” em La Villa, do escritor argentino César Aira, e do navio, em Opisanie Swiata, da escritora brasileira Veronica Stigger. A partir da ideia de “ilhas urbanas”, apontado por Josefina Ludmer (2013) sobre as literaturas pós-autônomas, a proposta pensa em como a escolha, nos livros, por explorar a convivência em reduzidos espaços diegéticos tensiona categorizações sociais, joga com totalizações identitárias e sugere novas visadas sobre a memória e os imaginários de um bairro, de uma cidade e mesmo de um país. Instigados pela proposição do pesquisador Mariano Siskind (2011) de que haveria, na literatura argentina do presente, um interesse maior com relação a elementos, realidades e narrativas locais que voltam a atenção em direção à abordagem de certa “argentinidade”, enquanto que na recente literatura brasileira imperaria um interesse cosmopolita, propomos discutir a expressão do nacional em um momento de literaturas pós-autônomas de recusa da alegoria.
Inquisição, controle e memória: relatos de vidas de freiras místicas no mundo hispânico
Authors: Rocha Karine
Published: December 2024

Este artigo tem por objetivo apresentar as memórias de freiras no Novo Mundo e suas estratégias de discurso para burlar as proibições impostas pelo Santo Ofício aos membros femininos da Igreja. Através da experiência mística, algumas religiosas do século XVIII aceitam participar de um jogo de poder, no qual simulam ser submissas para ganhar notoriedade na comunidade e expressar suas opiniões sobre temas religiosos. Utilizando-se de ferramentas como retórica da humilhação, bajulação e atribuições de suas falas à Deus, as freiras místicas um texto autobiográfico com características bastante próprias.
Fan fiction (‘ficção de fã’) como prática de multiletramentos
Authors: Lima Elizabeth Gonzaga
Published: December 2024

A ficção de fã ou fan fiction, na contemporaneidade, é um termo retomado dos fanzines ou revistas de fãs, oriundas das publicações amadoras de fãs de ficção científica nos Estados Unidos, na década de 1930. No entanto é possível retroceder ainda ao século XIV e encontrar a intervenção dos leitores com cortes e acréscimos aos textos ficcionais (MARTINS, 2014). O ficwriter intervém na escrita do autor modificando personagens, situações a fim de satisfazer seus desejos de mudança. Se por um lado, estes leitores são considerados “invasores do texto” na acepção de Henry Jenkins (2015), por outro, segundo o estudioso, fazem parte da denominada cultura participativa dos fãs, própria da era digital. É possível considerar a fan fiction um fenômeno na cena atual das linguagens midiáticas? Este modo de ler, escrever e interagir poderia oxigenar as práticas de letramento na escola? A fim de discutir sobre estas e outras questões relativas ao tema, o trabalho pretende examinar a hipótese de que as fanfics podem ser pensadas a partir de multiletramentos, ou seja, o letramento na primeira acepção que este conceito recebeu, de uso social da escrita, o letramento literário que utiliza a literatura para desenvolver as práticas de leitura e de escrita e o letramento digital, que emerge a partir da autonomia do leitor/internauta e da interatividade no universo virtual.
