Evaluation of Bioaccessibility of Vitamin C from Four Different Commercial Amla Products Using a Modified In Vitro Digestion Model
Authors: Chinnadurai Saravanan , Muralidharan Ananya , Venkataramanan Gokula Krishna , Kumar Keerthivarman , Ramu Akash Raj , Selvaraj Stalin
Published: March 2024

The present study aims to evaluate the bioaccessibility of vitamin C from 4 different Amla-based products compared with the Raw Amla using a modified dynamic customized in vitro digestion model. We chose 4 different amla products including amla juice, honey amla, dry amla, and amla powder for our study for the estimation of vitamin C. The results indicated that before in vitro digestion, the quantity of vitamin C is higher (45 mg/g) compared with other formulations. This may be due to the degradation of the amla matrix during powder making. Then, we carried out a dynamic in vitro digestion process sequentially from the mouth phase into the intestinal phase. Briefly, equal volumes of amla product and salivary enzymes were mixed thoroughly for 5 minutes, transferred to the stomach phase by mixing with porcine gastric juice, and made a pH of 3 for 2 hours. Finally, the digested foodstuffs were transferred and mixed with porcine intestinal juice for 2 hours. Once the intestinal digestion is finished, the overall digest is filtered using 0.3-micron filter paper for collecting micellar phase from the supernatant for vitamin C quantification. The results indicated that the amount of vitamin C entered the micellar is higher in the case of amla powder compared with other formulations (25 mg/g). Therefore, among the different amla products, dry amla (57.8 %) and amla juice (56.8%) exhibited better sources of vitamin C to facilitate bioactivity and also ameliorate vitamin C deficiency disorders.
"The Soul Should Have Been Brought along"
Authors: Lehtola Veli-Pekka
Published: March 2024

In the autumn of 1944, five hundred Skolt Sami were forced to leave their home region in the Pechenga (Petsamo) area together with other inhabitants. After the war, their fate was discussed by Finnish officials and in the media. The question was whether they should be returned to the Soviet Union or relocated to Finland. This article describes the five-year-long process to relocate the Skolt Sami to the Inari region. Following a recommendation by Håkan Rydving to focus studies on Sami agency, in addition to non-Sami actors whose role is usually emphasised, the aim of this article is to identify key actors who made crucial choices in the relocation process. In addition to the Finnish “Skolt friend” Karl Nickul, the Skolt Sami meetings and Jaakko Sverloff, the trustee of the Skolts, appear to have had important roles in key decisions, for example regarding the expansion of the Skolt area from Nellim to Sevettijärvi, the role of the winter village and the choice of settlements along the waterways.
Diverse Sami Livelihoods
Authors: Brännlund Isabelle
Published: March 2024

Swedish state policy regarding the Sami from the late nineteenth century onward and studies on Sami history have tended to treat reindeer husbandry as much more important than other livelihoods practiced by Sami communities and families. By comparing livelihood diversity in southern and northern mountain-reindeer husbandry communities in Swedish Sápmi (the traditional land of the Sami people) during the period 1860–1920, this study challenges the notions of Sami as reindeer herders and mountain reindeer husbandry as a nomadic monoculture. The results shows that Sami communities and families exploited diverse natural resources, trades and means of subsistence. The study supports an understanding of historical Sami livelihoods, were reindeer husbandry as recognized as one of various Sami trades and means of subsistence, rather than as the Sami livelihood.
Freeze-up, Break-up, and Colonial Circulation
Authors: Piper Liza
Published: March 2024

This paper examines the place of ice and snow in the process of Euro-Canadian colonisation of what are today the Yukon and Northwest Territories. Using oral histories and accounts of Indigenous life experiences from the late nineteenth and early twentieth centuries, the paper opens with an examination of the ways in which ice and snow, freeze-up and break-up, were inextricable from wider social and cultural relationships between Indigenous northerners and otherthan-human nature. Intensified trade and missionary activity after the mid-nineteenth-century along the Mackenzie and Yukon rivers and their tributaries created new colonial geographies, rhythms, and knowledge. These paid close attention to the character of ice, the timing of freeze-up and break-up, and the transportation possibilities of the open water season especially. By examining the histories of a scarlet fever epidemic in 1865 and an influenza epidemic in 1928, this paper uses the role of ice and its transformations in shaping the movements of pathogens to trace emerging northern colonial ecologies between 1860 and 1930.
North Actually
Authors: Gregersdotter Katarina
Published: March 2024

The article discusses and examines Larsson’s thus far five crime fiction novels to investigate how the formation of identity are connected to the peripheral North—the “real” North of the globally popular crime fiction subgenre Nordic Noir. Certain key concepts will be used to examine the novels: hyperlocalisation, neo-romanticism, anthropomorphism, borders, and history. This article will argue that in Åsa Larsson’s novels, place and its nature, borders and history are crucial in identity formation, and the place with its nature, climate and animals is an active agent in all the narratives.
Rural Resilience and Voluntary Work in the North of Sweden
Authors: Nilsson Bo
Published: March 2024

Rural areas in the north of Sweden are characterized by depopulation, unemployment and undermined social services. Due to the demands of economic growth and development, major cities in southern Sweden have been prioritized at the expense of the countryside. However, there have been many reactions to the dismantling of the welfare society in rural areas. People are also trying to counter and compensate for the impoverishment of the countryside through voluntary work. The overarching aim of this paper is to explore meanings of voluntary work in Sweden’s northern county of Västerbotten. More specifically, the aim is to investigate how different comprehensions of rural voluntary work are related to rural identities and to a resilient rural society. A central argument in the paper is that the relation between rural volunteer work and rural resilience is ambiguous. On one hand, volunteer work can contribute to rural resilience, since volunteering is a necessary course of action for people in the countryside to secure a necessary level of social services. On the other hand, rural volunteer work often has a traditional character, not always representing the capital of knowledge needed to maintain a sustainable rural lifestyle in the long run.
Cross-Border Cooperation Against the Odds?
Authors: Holm-Hansen Jørn , Aasland Aadne
Published: March 2024

What impact did changes in the geopolitical environment have on grassroots cross-border cooperation within the Barents Euro-Arctic Region in the years before Russia’s full-scale invasion of Ukraine in 2022? Drawing on interviews, surveys and document studies from two evaluations made in 2007 and 2020 of the Norwegian Barents Secretariat’s grant programme, conducted by the authors of the present article, we analyse the development over time of cross-border cooperation in Russia’s northwestern and Norway’s northernmost regions. The context in which the programme was conducted in 2020 differed significantly from that in 2007. The period was one of increasingly strained relations between Russia and the West. In particular, the 2014 events in Ukraine resulted in a new geopolitical environment that posed a challenge to the ideals of cross-border trust and people-to-people cooperation. Moreover, internal political developments in Russia led to more centralized power structures and control, also regarding civil society. Although we had expected these developments to have had a negative impact on the programme’s goal achievement, we find that the programme was closer to achieving several of its objectives in 2020 than in 2007. Competence transfer went both ways, both sides benefitted more equally and despite the geopolitical complications, the number of groups involved on both sides of the border did not decrease. The article identifies the main challenges between partners, and how they were overcome.

Northern Science and Research

Published: March 2024

The International Polar Year (IPY) provides an opportunity to reflect on Northern science and research. For all Canadians, science and research should contribute to living a good life. A good life includes successfully making sense of the world within local contexts, sharing this knowledge beyond the immediate community and reconciling it with knowledge held by outsiders. Northern science and research are inherent in Traditional Dene, Inuvialuit and Métis knowledge; and they continue to be reflected in Northern governance, economy, and cultures. Alongside Aboriginal sciences are Western sciences; these are primarily disciplinary in nature and formally structure postsecondary education globally. Postsecondary science and research education is still being introduced to the Northwest Territories (NWT). Over the last forty years the territorial government has developed the capacity for educational services, funding, institutions, and authority through the Department of Education, Culture and Employment. The delivery of Northern-based postsecondary education through Aurora College provides Northerners with the capacity to generate science and research in the North. What place do science and research have in the North? (North in this paper demarcates the socially constructed geopolitical territories north of the 60th parallel that we use cautiously as a structural term for the purposes of our narrative.) What kinds of investments need to be made and will Northerners be prepared to overcome barriers and take advantage of the opportunities?
The Relationship between Sami and Nordic Peoples Expressed in Terms of Family Associations
Authors: Mundal Else
Published: March 2024

The article investigates motifs from medieval sources and sources from early modern times in which the relationship between the Sami people and their Nordic neighbours is expressed in terms of family associations. During Romanticism it became a custom among Scandinavians to speak about each other as broderfolk, which in English is sister nations. In Old Norse sources it was the Sami people who were spoken of as “family,” but of a slightly more distant type than siblings. Haraldr hárfagri, who united Norway, married a Sami girl, Snæfríðr. Their marriage, which was a complicated one, may be seen as a symbolic expression of the problematic and loving relationship between two peoples. The king was the foster-son of the Sami people. To express the relationship between two peoples in terms of foster-child/foster-parent relations creates a picture with a very clear symbolic meaning. The kings of Norway from Haraldr harðráði on traced their family back to a Sami girl, and the earls of Hlaðir traced their family back to Sæmingr, probably the Proto-Sami. It may have been important, at least as a symbolic expression of community, that the princely houses of Norway had family roots in both peoples of the kingdom.
Collective Clan Disease among the Nanay
Authors: Bulgakova Tatiana D.
Published: March 2024

According to Nanay emic ideas, shamanic disease, which affects a shaman in the period of his or her formation, also affects his or her relatives, who begin to suffer from nervous disorders and other problems but recover at their new shaman’s incarnation. A similar spiritual correlation within the group of relatives becomes apparent also when a shaman is involved in a situation which connects him or her with the spiritual world (murder, death, incest, etc.), so that the consequences of such events influence not only the shaman, but also his or her kin.

From the emic perspective, relations with the spirits have not only spiritual, but also biological components (emerging for instance, in the idea about the possibility of human-spiritual cohabitation), which opens up possibilities for spirituality to be inherited by descendants. These circumstances suggest that the social factors that unite the clan (exogamy etc.), are secondary to the religious factors, and probably used as a means to adapt to the spiritual problems that shamanists face. Running the danger of collective clan disease, people have to remember their clan peculiarity and exclusiveness and undertake common efforts for its avoidance. Being aware of their patrilineal descent and of their own place in it, people can define the circle of possible persons who are subject to similar mental and other troubles and who should look together for the means of a cure. The wish to ensure spiritual security results in the social prescriptions and taboos that form the patrilineal clan.
A Resilient Subsistence Salmon Fishery in Southwest Alaska
Authors: Holen Davin
Published: March 2024

Harvesting and processing salmon is a significant subsistence activity for the residents of Nondalton, a predominantly Dena’ina Athabaskan community in Southwest Alaska. The Nondalton fishery, as a resilient social-ecological system, has had to adapt to change in order to maintain continuity over time. This paper will explore adaptation in a resilient salmon fishery through an ethnographic research project that documents the socio-cultural, economic, and environmental circumstances of fishing, mainly sockeye salmon (Oncorhynchus nerka), in the Kvichak Watershed of Southwest Alaska.
Citizens and Nomads
Authors: Gjengset Gunnar
Published: March 2024

The Sami author Matti Aikio from Karasjok made his debut in 1904 in Copenhagen with Kong Akab [‘King Akab’]. He was one of the world’s earliest indigenous authors, and presented his first novel to the Norwegian public with I dyreskind [‘In Hide’] in 1906. The last of a total of six novels was Bygden på elvenesset [The Parish on the Riverbank], launched posthumously in 1929.
In this article I present a post-colonial reading of this last novel of his. My hypothesis is that he wrote his first Norwegian novel anew, but this time social success amongst the Sami population is dependent upon the conduct of Sami culture. All of his novels reflect upon different strategies at hand for members of an ethnic minority in times of an advancing European industry, economy and culture, heavily influenced by a social-Darwinist political and anthropological cosmology.
Being the first registered Sami student of Norway, while writing his novels in Norwegian, Matti Aikio developed skills as a master of mimicry. Having experienced the importance of hybridity, he studies the limits of mimicry in his novels. This is the main project of his literary work, and with tools from post-colonial literary theories, this essay discusses the author’s attitudes to the possibilities of his own ethnic culture’s survival in the future.
Literacy and Trade in Late Medieval Norway
Authors: Hagland Jan Ragnar
Published: March 2024

Only faint traces can be observed of literacy connected to domains other than the legal sphere in late medieval Norway. This may be the result of poor archival practices for keeping written material not strictly connected to legal matters, such as the activities carried out by merchants and tradesmen. The present article tries nonetheless to study whether or not it is possible to relate the notion of literacy to trade in this period of time. The lack of evidence written in Roman letters may, it seems, to some extent be remedied by runic inscriptions excavated in medieval Norwegian towns. We must assume that the use of runes within the domain of trade grew out of an increasingly more complex organisation of mercantile activities which we see especially in an important port such as Bergen in the thirteenth and fourteenth centuries. It is, perhaps, not only due to chance that the discovered evidence seems to reflect the situation before the middle of the fourteenth century, when Bergen in particular was struck by the Great Plague. Whether the dramatic events caused by the Black Death did create a discontinuity in runic literacy connected to trade, we do not know.
„[A]lles öde und kahl, und somit echt isländisch“
Authors: Heitmann Annegret
Published: March 2024

Der Artikel stellt einen Reisebericht der Österreicherin Ida Pfeiffer in den Mittelpunkt, die im Jahr 1845 Island besuchte. Da Tourismus als ein Phänomen und Charakteristikum der Moderne gilt, lädt Pfeiffers Islandreise zu Fragen bezüglich der Anfänge touristischen und einer möglichen Authentizität frühmodernen Reisens ein. Der Authentizitätsbegriff, der heute oft im Zentrum neuer Tourismusforschung steht, stellt einen Einfallswinkel für die Analyse dar. Während die Autorin selbst die Ursprünglichkeit des Landes und die Echtheit ihres Erlebens hervorhebt, wird deutlich, dass sie eben diese Authentizität durch bestimmte Inszenierungsverfahren hervorbringt. So ist es nicht erstaunlich, dass – wie eine zeitgenössische Karikatur belegt – die Autorin schon in der Mitte des 19. Jh. in einen Tourismusdiskurs eingeschrieben wird.

A Revisionist History of Products Liability
Authors: Lahav Alexandra
Published: March 2024

Increasingly courts, including the Supreme Court, rely on ossified versions of the common law to decide cases. This Article demonstrates the risks of this use of the common law. The main contribution of the Article is to demonstrate that the traditional narrative about early products law—that manufacturers were not liable for injuries caused by their products because the doctrine of privity granted producers immunity from suit by the ultimate consumers of their goods—is incorrect. Instead, the doctrinal rule was negligence liability for producers of injurious goods across the United States in the nineteenth century. Courts routinely ignored or rejected privity arguments, and contract was not their paradigm for understanding a producer’s relationship with users of its products. This analysis has implications for how we view the development of the common law today. And it serves as a warning not to rely on potted histories from casebooks in determining what the common law was in the past.
Is There Anything Left in the Fight Against Partisan Gerrymandering? Congressional Redistricting Commissions and the “Independent State Legislature Theory”
Authors: Zeigler Derek , Urteaga Jose
Published: March 2024

Partisan gerrymandering is a scourge on our democracy. Instead of voters choosing their representatives, representatives choose their voters. Historically, individuals and states could pursue multiple paths to challenge partisan gerrymandering. One way was to bring claims in federal court. The Supreme Court shut this door in Rucho v. Common Cause. States can also resist partisan gerrymandering by establishing congressional redistricting commissions. However, the power of these commissions to draw congressional districts is at risk. In Moore v. Harper, a case decided in the Supreme Court’s 2022-2023 Term, the petitioners asked the Court to embrace the “Independent State Legislature Theory.” The ISLT, at a minimum, would allow federal review of state interpretations of state law governing congressional elections, including redistricting. Part I distills the Supreme Court’s opinions on redistricting commissions into two potential doctrinal routes: a more restrained version (ISLT-Lite) and a maximalist version (ISLT-Max). Part II proposes a framework to analyze existing congressional redistricting commissions for their constitutionality under each theory. Part III makes recommendations for building constitutionally sound congressional redistricting commissions under each theory, both for states with existing commissions and for those looking to reduce partisan gerrymandering in the future. While the future of ISLT, and congressional redistricting commissions more broadly, remains uncertain, this Note offers an analytical framework so states may continue to constitutionally alleviate partisan gerrymandering through the congressional redistricting commission framework.

Published: March 2024

O ensino de Física nas escolas ainda é um desafio para os professores e alunos. A abstração e complexidade dos temas pode tornar as aulas maçantes e desinteressantes. A impressão 3D, uma tecnologia emergente, é capaz de auxiliar no desenvolvimento de modelos antes tratados apenas em teoria por professores em diagramas e experimentos tridimensionais, possibilitando que os alunos envolvidos possam ter uma ferramenta que permita a elaboração de modelos que auxiliem na relação fenômeno-teoria e entendimento dos conceitos científicos. Este trabalho tem o objetivo de utilizar modelos elaborados em uma impressora 3D como ferramenta para a aprendizagem em Física. A metodologia consistiu em uma atividade de extensão em que os discentes do Ensino Médio de uma escola pública da cidade de Coari-Amazonas. tiveram a oportunidade de visualizar a elaboração dos materiais e contribuir com a construção do conhecimento em física. Verificou-se que a implementação das atividades práticas para a inserção dos conceitos científicos de física contribuiu para despertar o interesse dos alunos do ensino básico e oportunizou o entendimento de conceitos de física de forma mais concisa, proporcionando assim uma aprendizagem mais significativa.

Ensino híbrido nas aulas de Biologia: uma revisão sistemática de literatura
Authors: Marques Raimunda Aline Djanira Freire , Gallão Maria Izabel , Mota Erika Freitas
Published: March 2024

O ensino híbrido busca integrar o ensino tradicional com as possibilidades oferecidas pelas tecnologias de informação e comunicação, promovendo um aprendizado mais personalizado e adaptado às necessidades individuais dos alunos. Desde a pandemia do covid-19, o ensino híbrido aparece cada vez mais na rotina escolar, por se tratar de uma ferramenta pedagógica viável e eficaz no processo de ensino e aprendizagem. Assim, o referido trabalho tem como proposta desenvolver uma revisão sistemática de literatura acerca das contribuições do ensino híbrido nas aulas de Biologia, de modo a traçar um panorama geral sobre esse tema e caracterizar suas particularidades. O corpus investigativo provém de estudos primários publicados entre 2012 e 2022 em periódicos nacionais e internacionais. Para a elaboração deste projeto, foram definidos protocolos de busca e questões de pesquisa em quatro bases de dados distintas e, posteriormente, analisadas, resultando em dez trabalhos selecionados. Com a investigação dos estudos, concluiu-se que predominaram pesquisas cujo foco principal é o Ensino Médio, estando voltadas, principalmente, para os conteúdos relacionados ao Sistema Sexual, Ecologia, Parasitoses e Embriologia. A sala de aula invertida foi a metodologia híbrida mais utilizada na construção de novos saberes e os questionários foram os instrumentos de avaliação mais utilizados.
O poder do currículo na área das ciências da natureza e suas tecnologias: saúde no trabalho
Authors: Pedrolo Rodrigo , Krul Alexandre José
Published: March 2024

Este trabalho possui como objetivo investigar o comportamento do currículo na área das Ciências da Natureza e Suas Tecnologias (CNTs) por meio da biopolítica foucaultiana referente a saúde no trabalho. Para isso, foram analisados excertos nas habilidades da Base Nacional Comum Curricular (BNCC) e do Referencial Curricular Gaúcho do Ensino Médio (RCGEM) associadas a saúde no trabalho. Desfrutaremos das compreensões foucaultianas de arquivo como ferramenta teórico-metodológica para investigar os discursos, formados pelos enunciados, presentes na área das CNTs pelas referidas habilidades. Essas habilidades são vivenciadas pelo percurso estabelecido pelo currículo em regimentar os caminhos dos alunos e que, consequentemente, agem na proteção e prevenção de sua saúde no trabalho. Nesse universo, podemos associar ao discurso de Foucault sobre aumentar a vida da população – fazer viver, pensando nas condições existentes para a manutenção da saúde do aluno no trabalho.
História da Matemática e Etnomatemática: análise dos efeitos de uma ação pedagógica na Educação Básica
Authors: Santos Juliana Batista Pereira dos , Lara Isabel Cristina Machado de
Published: March 2024

Dentre as vertentes de pesquisa do campo de investigações em Educação Matemática, este artigo propõem uma articulação entre Etnomatemática e História da Matemática. O objetivo do texto é compreender os efeitos de uma ação pedagógica nos processos de ensino e de aprendizagem de Matemática de estudantes da Educação Básica.  A ação pedagógica em questão emergiu da realização de três propostas de ensino sobre Progressões Aritméticas, Logaritmos e Trigonometria, elaboradas a partir da articulação entre Etnomatemática e História da Matemática. Essa articulação é proposta à luz das teorizações pós estruturalistas de Michel Foucault, especialmente a partir dos conceitos poder e saber, e Ludwig Wittgenstein, por meio dos conceitos jogo de linguagem e regra. Como resultados, verifica-se que os efeitos observados evidenciam que a ação pedagógica contribuiu para a aprendizagem matemática dos estudantes e oportunizou o reconhecimento e a compreensão de que os jogos de linguagem presentes na Matemática são um modo de matematizar, entre outros.
Development of a WAO Learning Module for the Absorption Topic of Year One Science
Authors: Mohd Razak Nur Raihana , Mat Daud Anis Nazihah , Ariffin Nurul Hazwani , Abdullah Norazilawati , Hasim Nurhafizah
Published: March 2024

Teaching and Learning at Home (TLH) provides a challenge to Science subject since it needs to be learned without relying entirely on the teacher. Learning using modules is one of the methods of TLH that can be implemented to help teachers in teaching Science subject. Therefore, this study was performed to develop a WAO learning module for the Absorption topic of Year One Science subject. The development of the module according to ADDIE instructional design but this study only focused on the development and validity evaluation of the module which were included in the development phase. The module was developed to apply the structured inquiry learning strategy. The development of the WAO learning module comprised the development phase and validity evaluation phase of the module. The developed WAO self-learning module consisted of three units namely Unit 1 (water-absorbing objects), Unit 2 (types of material and water-absorbing capacity) and Unit 3 (water-absorbing objects and daily life). The findings of the study showed that the module had a high percentage of expert agreement values of 98% and 97% in terms of face validity and content validity. In conclusion, this study has successfully developed the WAO learning module which had high face validity and content validity. The implication of this study is the developed WAO learning module can be used as a learning module for TLH sessions. The module is expected to attract students to study Science subject, encourage them to be active during TLH sessions and increase their understanding towards Absorption topic.

Published: March 2024

Combinatorial Game Theory is a branch of mathematics and theoretical computer science that studies sequential 2-player games with perfect information. Normal play is the convention where a player who cannot move loses. Here, we generalize the classical alternating normal play to infinitely many game families, by means of discrete Richman auctions (Develin et al. 2010, Larsson et al. 2021, Lazarus et al. 1996). We generalize the notion of a perfect play outcome, and find an exact characterization of outcome feasibility. As a main result, we prove existence of a game form for each such outcome class; then we describe their lattice structures. By imposing restrictions to the general families, such as impartial and symmetric termination, we find surprising analogies with alternating play.
Schnyder Woods and Alon-Tarsi Number of Planar Graphs
Authors: Kozik Jakub , Podkanowicz Bartosz
Published: March 2024

Thomassen in 1994 published a famous proof of the fact that the choosability of a planar graph is at most 5. Zhu in 2019 generalized this result by showing that the same bound holds for Alon-Tarsi numbers of planar graphs. We present an alternative proof of that fact, derived from the results on decompositions of planar graphs into trees known as Schnyder woods. It turns out that Thomassen’s technique and our proof based on Schnyder woods have a lot in common. We discuss and explain the prominent role that counterclockwise 3-orientations play in proofs based on both these approaches.

First, I would like to thank Professors Dang, Matei, and Popovic for putting together this fine collection of papers on academic freedom. In this volume, there also appear three additional articles submitted for publication in an open issue. I have made the decision to include these
excellent articles in a separate section of this special issue so as to not delay their publication unnecessarily.
Analysis of Ethnopharmacological Studies on the Use of the Sambiloto Plant in the Treatment of Malaria in the Asmat Tribal Community in Papua, Indonesia
Authors: Awotauw Esther Lea , Ruth Maria Panggabean
Published: March 2024

Introduction: Malaria is still a major health problem in Indonesia, especially in the Papua region. The Asmat tribe has traditional knowledge about the use of medicinal plants to treat malaria, one of which is sambiloto.

Methods: This research uses a qualitative observational research design with an ethnopharmacological approach. This approach combines aspects of ethnography and pharmacology to study traditional knowledge and the use of medicinal plants in a community.

Results: It was discovered that sambiloto has long been used by the Asmat tribe to treat malaria. Sambiloto leaf is processed into a decoction or juice and drunk to relieve malaria symptoms such as fever, chills, and headaches.

Conclusion: This ethnopharmacological study shows that sambiloto has potential as an herbal medicine for treating malaria in the Asmat community. Further research is needed to test the effectiveness and safety of sambiloto in the treatment of malaria.
An Op-Amp-Based PID Control of DC-DC Buck Converter for Automotive Applications
Authors: Boutaghlaline Anas , El Khadiri Karim , Tahiri Ahmed
Published: March 2024

The present paper introduces the design and simulation of an op-amp-based PID-controlled DC-DC buck converter to regulate a DC voltage of 12 V to 5 V and support load currents ranging from 1 A to 5 A for automotive applications using LTspice software. The converter operates at a switching frequency of 550 kHz, delivering a regulated output voltage of 5 V for load currents ranging from 1 A to 5 A, with a maximum output voltage ripple of 47.56 mV. The proposed buck converter settles to its regulated value within 943.4 µs at a load current of 1 A, with a peak efficiency of 92.83%. The simulation results of the proposed buck converter response to load current fluctuations show that the buck converter settles to its regulated value in 83.36 µs during a load current change from 1 A to 5 A with an undershoot of 92.62 mV. Conversely, during a load change from 5 A to 1 A, the proposed buck converter recovers from an overshoot of 52.04 mV within 46.32 µs.
Design of Fractional Calculus Free Controllers with Fractional Behaviors
Authors: Sabatier Jocelyn
Published: March 2024

Faced with the complexity and drawbacks of fractional calculus highlighted in the literature, this paper proposes simple solutions to avoid its use in the field of feedback control and especially to define fractional PID- and CRONE-like controllers. It shows that it is possible to generate fractional behaviors, which are known since the work of Bode to be useful in the field of control, without invoking fractional calculus and fractional models. Fractional calculus based models and fractional behaviors are indeed two different concepts: one denotes a particular class of models and the other a class of dynamical behaviors that can be generated and modelled by a wide variety of mathematical tools other than fractional calculus. Solutions to tune the fractional PID- and Crone-like controllers defined in this paper are proposed.
Chandrasekhar-type Algorithms with Gain Elimination
Authors: Assimakis Nicholas , Adam Maria
Published: March 2024

Chandrasekhar-type algorithms are associated with the Riccati equation emanating from the Kalman filter in linear systems which describe the relationship between the n-dimensional state and the m-dimensional measurement. The traditional Chandrasekhar-type algorithms use the Kalman filter gain to compute the prediction error covariance. In this paper, two variations of Chandrasekhar-type algorithms eliminating the Kalman filter gain are proposed. The proposed Chandrasekhar-type algorithms with gain elimination may be faster than the traditional Chandrasekhar-type algorithms, depending on the model dimensions.
A Class of Population Mean Estimators in Stratified Random Sampling: A Case Study on Fine Particulate Matter in the North of Thailand
Authors: Lawson Nuanpan , Thongsak Natthapat
Published: March 2024

Residents of Thailand’s upper northern have been facing hazardous air quality with the amount of fine particulate matter rising several times higher than the standards of the World Health Organization for many years which is classified as a level that severely affects public health. The dust problem is an urgent issue in Thailand that needs to be solved. Assessment of pollution data in advance can help the Thai government in planning to abolish and prevent ongoing dust problems for Thai citizens. A new class of population mean estimators is proposed under stratified random sampling. The bias and mean square error of the proposed estimators are studied using a Taylor series approximation. A simulation study and an application to air pollution data in the north of Thailand to investigate the performance of the estimators. The results from the air pollution data in the north of Thailand present that the proposed estimators offer the highest efficiency concerning others.

Введение. Представлена оценка периоперационных и отдаленных результатов эвисцераций органов малого таза у пациентов с первичным местно-распространенным и местно-рецидивирующим колоректальным раком.
Материалы и методы. В период с 2005 по 2022 гг. в ГБУЗ ЛОКОД им. Л.Д. Романа выполнено 206 операций. Средний возраст пациентов составил 61 год, женщин — 168 (82 %) и мужчин — 38 (18 %). Характер и вид выполненных эвисцераций: тотальная супралеваторная с анастомозом — 28 (13,6 %), тотальная супралеваторная без анастомоза — 14 (6,8 %), тотальная инфралеваторная — 20 (9,7 %), передняя эвисцерация с резекцией влагалища — 1 (0,5 %), задняя надлеваторная эвисцерация с анастомозом — 65 (31,6 %), обструктивная задняя надлеваторная эвисцерация — 48 (23,3 %), задняя инфралеваторная эвисцерация — 30 (14,5 %).
Результаты. Послеоперационные осложнения развились у 106 (51,5 %) пациентов. Летальность составила 8,7 %. Выживаемость в подгруппе R0 резекций составила: 3-х летняя и 5-ти летняя — 56,5 % (95 % ДИ 48,3–66,2) и 47,3 % (95 % ДИ 38,5–58,1) соответственно. Наблюдалась статистически значимая разница в общей 5-летней выживаемости между пациентами с R0 и R1/R2 резекцией (р = 0,01). Медиана выживаемости составила для пациентов из группы резекции R0 — 26 месяцев, в группе R1/R2 резекции — 11 месяцев.
Выводы. Наиболее важным прогностическим фактором для оценки выживаемости является достижение резекции в объеме R0. Характер опухоли на результаты отдаленной выживаемости не повлиял. Выполнение эвисцераций органов малого таза целесообразно в высокопотоковых центрах.
