Authors: Houbertz Ruth , Hartinger Verena , Klein Jan J. , Herder Martin , Grützner Gabi , Dannberg Peter
Published: March 2021

The continuous miniaturization of components and devices along with the increasing need of sustainability in production requires materials which can fulfill the manifold requests concerning their functionality. From an industrial point of view emphasis is on cost reduction either for the materials, the processes, or for both, along with a facilitation of processing and a general reduction of resource consumption in manufacturing. Multifunctional nanoscale materials have been widely investigated due to their tunable material properties and their ability to fulfill the increasingly growing demands in miniaturization, ease of processes, low-cost manufacturing, scalability, reliability, and finally sustainability. A material class which fulfills these requirements and is suited for integrated or waferscale optics are inorganic–organic hybrid polymers such as ORMOCER®s [ORMOCER®is registered by the Fraunhofer Gesellschaft für Angewandte Forschung e.V. and commercialized by microresist technology GmbH under license since 2003]. The combination of chemically designed multifunctional low-cost materials with tunable optical properties is very attractive for (integrated) optical and waferscale applications via a variety of different nano- and microstructuring techniques to fabricate micro- and nano-optical components, typically within less than a handful of process steps. The influence of photoinitiator and cross-linking conditions onto the optical properties of an acrylate-based inorganic–organic hybrid polymer will be discussed, and its suitability for being applied in waferscale optics is demonstrated and discussed for miniaturized multi- and single channel imaging optics.

Published: March 2021

Objectives

Patients in Intensive Care Units (ICU) are a high-risk population for sepsis, recognized as a major cause of admission and death. The aim of the current study was to evaluate the diagnostic accuracy and prognostication of monocyte distribution width (MDW) in sepsis for patients admitted to ICU.

Methods

Between January and June 2020, we conducted a prospective observational study during the hospitalization of 506 adult patients admitted to the ICU. MDW was evaluated in 2,367 consecutive samples received for routine complete blood counts (CBC) performed once a day and every day during the study. Sepsis was diagnosed according to Sepsis-3 criteria and patients enrolled were classified in the following groups: no sepsis, sepsis and septic shock.

Results

MDW values were significantly higher in patients with sepsis or septic shock in comparison to those within the no sepsis group [median 26.23 (IQR: 23.48–29.83); 28.97 (IQR: 21.27–37.21); 21.99 (IQR: 19.86–24.36) respectively]. ROC analysis demonstrated that AUC is 0.785 with a sensitivity of 66.88% and specificity of 77.79% at a cut-off point of 24.63. In patients that developed an ICU-acquired sepsis MDW showed an increase from 21.33 [median (IQR: 19.47–21.72)] to 29.19 [median (IQR: 27.46–31.47)]. MDW increase is not affected by the aetiology of sepsis, even in patients with COVID-19. In sepsis survivors a decrease of MDW values were found from the first time to the end of their stay [median from 29.14 (IQR: 26.22–32.52) to 25.67 (IQR: 22.93–30.28)].

Conclusions

In ICU, MDW enhances the sepsis detection and is related to disease severity.
Predicting syntactic choice in Mandarin Chinese: a corpus-based analysis ofbasentences and SVO sentences
Authors: Fang Yu , Liu Haitao
Published: March 2021

This paper investigates the effects of 10 factors on the choice between alternativebasentences and SVO sentences in Mandarin Chinese. These factors are givenness, definiteness, animacy and pronominality of NP2s, NP2 length, VP length, verb sense, syntactic parallelism, dependency distance, and surprisal. Using corpus data and mixed-effects logistic regression modeling, we find that on the one hand, givenness, syntactic parallelism, and the log-transformed ratio of NP2 length and VP length are significant predictors of the choice betweenbasentences and SVO sentences. A new NP2, a large length ratio and a parallel construction predict an SVO sentence rather than abasentence. On the other hand, dependency distance and surprisal estimated by the trigram model are effective in predicting the choice between naturally occurringba/SVO sentences and their alternatives. Naturally occurring sentences are more likely to have shorter dependency distances and smaller surprisal values than the converted sentences. The effects of these five factors on syntactic choice are congruent with results of previous studies, which suggests that some determinants of syntactic choice are shared among languages.
Overutilization and underutilization of autoantibody tests in patients with suspected autoimmune disorders
Authors: Rajendran Rajkumar , Salazar Jose H. , Seymour Robert L. , Laposata Michael , Zahner Christopher J.
Published: March 2021

Objectives

Diagnostic Management Teams (DMTs) are one strategy for reducing diagnostic errors. This study examined errors in serology test selection after a positive antinuclear antibody (ANA) test in patients with suspected systemic autoimmune rheumatic disorder (SARD).

Methods

This retrospective study included 246 patient cases reviewed by our ANA DMT from March to August 2019. The DMT evaluated the appropriateness of tests beyond ANA screening tests (overutilization, underutilization, or both) based on American College of Rheumatology recommendations and classified cases into diagnostic error or no error groups. Errors were quantified, and patient and provider characteristics associated with diagnostic errors were assessed.

Results

Among 246 cases, 60.6% had at least one diagnostic error in test selection. The number of sub-serology tests ordered was 2.4 times higher in the diagnostic error group than in the no error group. The likelihood of at least one diagnostic error was higher in males and African American/Black patients, although the differences were not statistically significant. Providers from general internal medicine, primary care, and non-rheumatology specialties were approximately two times more likely to make diagnostic errors than rheumatology specialists.

Conclusions

Diagnostic errors in test selection after a positive ANA for patients with suspected SARD were common, although there were fewer errors when ordered by rheumatology specialists. These findings support the need to develop strategies to reduce diagnostic errors in test selection for autoimmunity evaluation and suggest that implementation of a DMT can be useful for providing guidance to clinicians to reduce overutilization and underutilization of laboratory tests.

Viele Menschen mit geistiger Behinderung sind aufgrund ihrer Wohn- und Betreuungsform sowie von behinderungsassoziierten Faktoren und einer erhöhten Morbidität deutlich stärker von COVID-19 betroffen als die Durchschnittsbevölkerung. Hinzu kommen gesundheitliche Folgen durch einschränkende Maßnahmen der Expositionsprophylaxe zu Beginn der Pandemie. Public-Health-Maßnahmen sind dann wirksam, wenn sie die große Heterogenität und die jeweiligen Lebensbedingungen der Menschen mit geistiger Behinderung berücksichtigen.
On the logical form and ontology of inferences in conversational implicatures
Authors: Perrin Denis
Published: March 2021

This paper is about the pragmatic inferences in play as conversational implicatures (Grice, P. 1989.Studies in the way of words. Cambridge, MA: Harvard University Press) occur. First, it constructs the deductivism versus abductivism debate that transpires from the extant literature but is rarely elaborated. Against deductivism, the paper argues that implicating inferences in conversational implicatures can instantiate an abductive logical form, as abductivism suggests. Against abductivism, however, it grants to deductivism that implicating inferences can have a deductive form provided the latter is of a defeasible type. In sum, it thus argues forpluralist defeasibilism. Second, it turns to the issue of the ontological nature of implicating inferences and advocatesnormative inferentialism, on which these inferences are not primarily real psychological processes but rules of the practice of implicating. While this allows for the possibility of their psychological instantiation, to be sure, the paper also insists that psychological inferring processes in implicatures are neither necessarily isomorphic to the aforementioned rules nor even necessarily occur as an implicature occurs.
Marketing as an economic science
Authors:   Odessa National Polytechnic University, Oklander Mykhailo
Published: March 2021

The aim of the article. The purpose of the article is to form evidence that marketing is an economic science. The results of the analyses. Marketing is an economic science that studies the problem of sales in the capital cycle, ie the issue associated with the transformation of the commodity form of the value of capital into the monetary form of the value of capital. Marketing in terms of commodity production solves the problem of sales in the capital cycle. The reason for the emergence of marketing is the emergence of the buyer's market at the stage of mechanization of the industrial stage of commodity production. The subject of the study of marketing is the study of the problem of sales in the capital cycle. The essence of marketing is a support at the stage of sale of the continuity of the capital cycle. Marketing, like any economic sciense, is evolving, and the stages of evolution must be tied to the way goods are produced. Since the advent of classical marketing theory, the method of production has changed, so it is logical to assume that its periodization should change adequately. In the context of digitalization of the economy, the Internet and other digital channels are changing the forms and methods of marketing, the era of omnichannel marketing has come, the marketing of the XXI century. Conclusions and perspectives for further research. Marketing is the result of the development of four economic doctrines: mercantilism, classical and neoclassical political economy, marginalism, institutionalism. The genetic roots of marketing go back to the early stages of capitalism, and the evolution of marketing theory is intertwined with the evolution of economic theory. With the digitalization of the economy, the Internet and other digital channels are changing the forms and methods of marketing, the era of omnichannel marketing has come. Automation, targeting, personalization, video content, multimedia projects, online marketing research modernize marketing in form. But the mission of marketing remains the same as to solve the problem of sales in the capital cycle of enterprises. In the future it is necessary to study the evolution of the marketing paradigm taking into account the changes in technological systems during the XX-XXI centuries. Keywords: marketing, economics, mercantilism, political economy, marginalism, institutionalism, omnic marketing.
Handle with Care

The late 2018 publication of Donald Westbrook’s Among the Scientologists marks the culmination of a decade of increased scholarship on the Church of Scientology from a variety of scholarly perspectives. In conversation with the Religious Studies Project (RSP) panel on ‘New Directions in the Study of Scientology’ held at the British Association for the Study of Religion (BASR) in November 2018, this academic comment seeks to highlight some of the internal and external factors which work to make the study of Scientology a potential minefield for scholars of New Religions. In addition to this I offer four modest proposals for how those within the academy might work toward overcoming some of these challenges, in particular the polarization between different camps within the study of New Religions.

The effect of the γ'- and β-phase particles on the thermoelastic γ-α' martensitic transformation (MT) during cooling/heating and under stress was studied under tension and compression on the [001]-oriented single crystals of Fe-28%Ni-17%Co-11.5%Al-2.5%Ti (at.%) alloy. The effect of the aging regime on the Ms temperature was shown. Maximum increase in the Ms temperature by 100 K was found with the simultaneous precipitation of the γ'- and β-phase particles after two-stage aging of 4+4h at 873 K, in comparison with single-stage aging for 8h. In crystals with γ' and γ'+β-phases particles the difference (asymmetry) of the stresses for the stress-induced γ-α' MT σcr and value α = d σcr/ dT under tension and compression were not observed. The absence of asymmetry of the σ cr and value α = d σcr/ dT are due to close values of the shape memory effect (SME) and superelasticity (SE) under tension and compression. The values of SME and SE were decreased when β-phase particles are precipitated.

Plane electromagnetic waves in an isotropic absorbing chiral medium (chiral metamaterial) are considered. A system of constitutive Drude - Born - Fedorov relations with complex values of the dielectric permittivity, magnetic permeability, and the chirality parameter is used. A distinction is made between forward and backward normal waves by introducing a special parameter - the wave type identifier. Analytical expressions for real and imaginary parts of wave numbers of homogeneous normal waves are presented.

In the present work, a weighed maximum likelihood method (WMLM) is proposed to obtain robust estimates for processing experimental data containing outliers. The method allows robust asymptotic unbiased and effective estimates to be obtained in the presence of not only external, but also internal asymmetric and symmetric outliers. Algorithms for obtaining robust WMLM estimates are considered at the parametric level of aprioristic uncertainty. It is demonstrated that these estimates converge to maximum likelihood estimates of an inhomogeneous sample for each distribution from the Tukey supermodel.

The mechanisms of increasing the resistance of copper samples treated with a high-energy beam of nitrogen ions to adhesive wear during friction together with a copper counterbody in an argon atmosphere are studied. It was shown that the increase in wear resistance is complex and is associated with the action of mechanisms such as solid-solution hardening, grinding of copper grains, precipitation of the finely dispersed CuN3 phase, increase in the density of dislocations and internal stresses of the second kind in the surface layer . The maximum increase in wear resistance and microhardness (~ 4 and ~ 2.6 times, respectively, compared with the original copper) is observed about ion fluence of ~ 9×1017 ion/cm2. A further increase in fluencies leads to a decrease in wear resistance and microhardness due to the enlargement of the pores formed in the surface layer of copper as a result of implantation of nitrogen ions.

The stress-strain state on the interface of the elastic solids is investigated. The studied interface presents a contact layer which is characterized by dimension and the set of physics mechanical parameters. The models of layered and block medium are used for the description this boundary. In the framework of these models the problem of elastic wave propagation through the interface is considered. Analytical expressions for the refraction and reflection coefficients allowing us to determine the strains on the interface and strains distribution in the contact layer are found. Corresponding strains amplitudes depending on the layer thickness are calculated at the different elastic parameters of contacting solids and boundary. The strain laws on the interface which is described by the layered and block medium models are analyzed. The regions of equivalent use these models are determined in the case of strain analysis on the boundary and the strain distribution in the contact layer.

We observed the formation of bimetallic nanoparticles with a number average size of 75 ... 82 nm by synchronous and nonsynchronous electric explosion of wires. The phase composition of the samples is represented by phases based on solid solutions of copper and silver. The results of the studies allow us to conclude that, using electric explosion of copper and silver wires, bimetallic Ag-Cu nanoparticles with different mass ratio of metals can be obtained.
Поляризация социально-экономического пространства в регионах староосвоенного Центра России: пример Ярославской области
Authors: Аверкиева Ксения Васильевна , Нефедова Татьяна Григорьевна , Кондакова Татьяна Юрьевна
Published: March 2021

В статье рассматриваются процессы поляризации и сжатия освоенного пространства регионов Центра России за пределами Московской области, имеющих продолжительную историю хозяйствования и богатое не только культурное, но и промышленное наследие. Основные исследовательские вопросы касаются выявления предпосылок и социально-экономических последствий поляризации социально-экономического пространства и  оценки роли наследия староосвоенности. Рассматриваются эволюция хозяйственного освоения старопромышленных регионов Центральной России и смена его типов, особенности советской индустриализации в городах и унификации сельских районов, а также постсоветские трансформации хозяйства. Детально проанализированы основные процессы последних десятилетий: концентрация промышленности, сжатие сельскохозяйственного производства, изменение расселения, современные миграции. Исследование включало анализ исторической литературы, обработку данных региональной и муниципальной статистики и полевых исследований в муниципальных районах Ярославской области, выбранной в качестве ключевого региона. Показано, что региональные центры развиваются благодаря модернизации и реосвоению старых промышленных площадок, созданию новых промышленных парков и постиндустриальных предприятий. Малые города в целом стагнируют и теряют население, хотя имеют разные траектории развития, которые определяются широким набором факторов – от географического положения до богатства культурного наследия и наличия активных жителей. Поляризация сельской местности проявляется в нарастании контрастов между пригородами с высокой плотностью населения и хозяйства и территориальными конфликтами, с  одной стороны, и периферией, где стремительно сокращается сельское население, с другой, что свидетельствует о наследуемом советском инварианте организации пространства. Возрождение сельского хозяйства характерно лишь для отдельных очагов и основано на создании новых модернизированных предприятий в ареалах с лучшими природными условиями. Рассматривается противоречивость процессов модернизации, поляризации освоенного пространства и использования исторического наследия. Отдельное внимание уделяется роли человеческого потенциала в появлении локальных точек роста. Анализируются возможности не только репродукции и модернизации прежних видов хозяйствования, но и формирования новых функций, включая рекреационное ландшафтно-культурное и дачное природопользование, возникшие благодаря использованию внутренних и внешних ресурсов.

The novel coronavirus disease 2019 (COVD-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The immunothrombosis could occur during infectionwith viruses. Deep vein thrombosis (DVT) is a devastating condition that usually involves the lower extremities. The typical course of DVT is associated with an episode of enormous limbswelling and pain. In this case report, we aimed to present one of the COVID-19 possible complications: DVT in a 38 years old man infected with SARS-CoV-2. A 38 years old manpresented with leg pain. He had a dry cough and fatigue suspicious symptoms of COVID-19. For further evaluations, the lung Computed Tomography scan (CT-scan), labratoricalassessments, and doppler sonography of the common femoral vein (CFV) of both legs were done. Also, for investigating the other underlying causes of DVT, abdominopelvic CT-scan andlumbosacral Magnetic Resonance Imaging (MRI) were done. The CT-scan showed GroundGlass Opacity (GGO) view. Labratorical assessment proposed a thrombotic condition. Thedoppler sonography of the CFV of both legs revealed a massive thrombosis in the left CFV suggesting an acute DVT. Abdominopelvic CT-scan and lumbosacral MRI were negativefor other underlying causes of DVT. COVID-19 is associated with the classical syndrome named disseminated intravascular coagulation and the subsequent consumption coagulopathypresented as DVT.
Formation and Development of Investigation of Misdemeanours as a Form of Pre-trial Investigation in Ukraine (the 18th–19th Centuries)
Authors: Galagan Volodymyr , Yakovenko Mykola
Published: March 2021

The article deals with the preconditions of differentiation of forms of pre-trial investigation in Ukraine in the 18th–19th centuries. The concept of investigation of misdemeanours as a form of pre-trial investigation at different stages of social development are considered. The base source of the Russian Empire is examined, with the aspects of using of the term “investigation of misdemeanours” in law enforcement practice thoroughly covered. It is established that this term at the legislative level and in the literary sources held for a long time is subject to transformation in terms of its functional direction. The paper offers a description of the study of the early stage of development and a comparison with the modern form of pre-trial investigation. It is established that at all stages of its development there is a common feature: the provision of a simplified order.The article presents the key differences between the knowledge at the early stage of its creation and the modern form of pre-trial investigation. However, the investigation of misdemeanours starts from the moment of the illegal act until the end of the pre-trial investigation. At first, this investigation of misdemeanours had few signs of research verification. The collected materials were examined by the proceedings and could not be determined by full evidence without appropriate “legalization” procedures. The investigation of misdemeanours had not clearly defined a procedural form and was not limited to specific deadlines, and depended almost entirely on the inner convictions of the individual who conducted this knowledge. In the legislation of the pre-revolutionary period, the investigation of misdemeanours should be carried out by a wide range of authorized persons (police ranks, military and civilian authorities, clergy, government officials, village elders, and others). The investigation of misdemeanours was carried out in everything without exception of crime, regardless of its severity at those times.It is proved that the modern model of pre-trial investigation represents the positive historical experience and the right opinion. Today we can observe a consistent procedure of the implementation of the exercise, a special circle of authorized persons, and the introduction of a balance of appropriate differentiation of forms of pre-trial investigation.

Authors: Karthiayani A. , Ganga M. Udaya , Kumar C. Ashok
Published: March 2021

Background: Despite the fondness for noodles, consumers in India hold the notion that noodles are being made from maida which is seen as product with low fiber. Hence an attempt was made to develop fiber enriched noodles by incorporating banana pseudo-stem tender core powder (BPP) as a fiber source. Methods: BPP was incorporated at different levels viz., 5, 10 and 15% in which 5% was found to be the best based on cooking characteristics and sensory evaluation. The noodles thus prepared were packed in flexible polyethylene pouches and stored at room temperature and were further analyzed for physicochemical, cooking, sensory and colour characteristics at regular intervals of 60 days till 180 days of storage. Result: All the analysis showed the non-significant difference during the storage period stating that the product is good till 180 days of storage. The dietary fiber was found to increase from 3.35 to 4.74% and in vitro method of glycemic index (GI) analysis showed that the fiber noodle was a low GI food when compared to the medium GI of control. The MUFA and PUFA content of BPP noodles were increased when compared to control.

Published: March 2021

Background: Humic substances plays a vital role in the plant tissue culture as a growth hormone for in vitro propagation of many plant seedlings. The aim of this study was to investigate the effect of added humic-fulvate complex (HFC) at the various concentrations on the growth and development of grape seedlings in in vitro at the different nutrient levels. Methods: The cutting of khasansky grape were cultivated on ¼ Murashige and Skoog medium or ½ Murashige and Skoog medium either alone or supplemented with the humic-fulvate complex at the different concentrations at (0.1, 1 and 10 ml/l). Then, they were cultured for 4 weeks under a controlled environment. Result: The data observed that the low concentration of Murashige and Skoog medium (¼ MS) for in vitro rooting of grape cv. ‘Khasansky’ either alone or combined with HFC at the various concentrations significantly increased the rooting percentages and the total length of roots and stimulating the rate of vegetative growth compared with cultivated in ½ MS medium either alone or with supplemented with HFC. ¼ MS+ 10 ml/l HFC was the best treatment for improving the growth of khasansky grape seedlings.

Indonesia is famous for its diverse cultures, and unwittingly from each culture has a different appeal. In the culture itself, there is a science that is not widely known by people, besides local wisdom from several regions can be used as a source of learning science. So far, science learning, especially in physics, still refers only to a handbook of teachers and students, where it contains science products in the form of facts, concepts, principles, theories, and laws and their application in the context of daily life. However, many books often contain contexts of daily life related to western culture that is not well recognized by Indonesian children, especially those in certain areas who still rely on nature as a learning media. Based on these problems, the aim to observe the application of physics in Indonesia's national culture. The researcher intended to identify the concept of equilibrium and moments force in the technique of the Dhadak Merak dance movement in Reog Ponorogo. This type of research is an analytical study by using documentation studies and the research target is Dhadak Merak Dance.  Data collected by the observation method and analysis method using literature study and training video. According to the results of the research, physics concept studies were obtained, especially in equilibrium materials and moments force in the Dhadak Merak Dance, and learning with an ethnoscience approach has the potential for innovation learning to be applied in physics learning because it can train students science literacy and train students to think creatively.

The concept of fuzzy subgroups is a combination of the group structure with the fuzzy set, which was first introduced by Rosenfeld (1971). This concept became the basic concept in other the fuzzy algebra fields such as fuzzy normal subgroups, anti fuzzy subgroups and anti fuzzy normal subgroups. The development in the area of fuzzy algebra is characterized by the continual emergence of new concepts, one of which is the α-anti fuzzy subgroup concept. The idea of α-anti fuzzy subgroups is a combination between the α-anti fuzzy subset and anti fuzzy subgroups. The α-anti subset fuzzy which is an anti fuzzy subgroup is called as α-anti fuzzy subgroup. The purpose of this study is to prove that the α-anti fuzzy subset is an anti fuzzy subgroup, examine the relationship between α-anti fuzzy subgroups with anti fuzzy subgroups and α-fuzzy normal subgroups with anti fuzzy subgroups. The results of this study are, if A is an anti fuzzy subgroup (an anti fuzzy normal subgroup), then an α-anti subset fuzzy of A is an anti fuzzy subgroup (an anti fuzzy normal subgroup). However, this does not apply otherwise. Furthermore, this study also provides sufficient and necessary conditions for an α-anti fuzzy subset of any group to be an α-anti fuzzy subgroup and the formation of a group of factors that are built from an α-anti fuzzy normal subgroup.Keywords : Anti Fuzzy Subgroup, Anti Fuzzy Normal Subgroup, α-Anti Fuzzy Subgroup and α-Anti Fuzzy Normal Subgroup.

Penelitian ini bertujuan untuk mengetahui aktifitas antioksidan dari ekstrak belut (Monopterus albus) yang hidup di perairan provinsi jambi. Radikal bebas cenderung menimbulkan reaksi berantai yang apabila terjadi di dalam tubuh akan dapat menimbulkan kerusakan sel yang berlanjut dan terus menerus terutama pada penyakit kronis seperti diabetes, hipertensi dan hiperkolesterol. Pencegahan dapat dilakukan dengan memberikan seyawa antioksidan, salah satunya asam amino. Di dalam al-Quran disebutkan bahwa bangkai yang halal untuk dimakan adalah ikan dan belalang. Belut merupakan salah satu jenis ikan yang memiliki kandungan albumin yang tinggi. Sampel daging belut yang telah difillet dan dipisahkan dari kepalanya, dipotong kecil-kecil dengan ukuran 1,5 cm2 dan dibalut dengan kain tipis dalam sebuah mangkuk, lalu dikukus, dipress, dan disentrifus.  diambil fase air dan minyak dan dibuang pengotornya dengan cara disaring, lalu dikeringkan menggunakan freeze drying sehingga diperoleh ekstrak belut dalam bentuk serbuk. Metode yang digunakan pada penelitian ini adalah Radical Scavenging method menggunakan senyawa kimia DPPH (2,2- difenil-1-pikrilhidrazil). Dari hasil penelitian ditemukan bahwa nilai IC50 ekstrak belut sebesar 29,0816 ppm. Ekstrak belut memiliki potensi menangkal radikal bebas dengan aktifitas kuat. Kata Kunci: Ektstrak Belut, Monopterus albus, Penangkal Radikal Bebas This study aims to determine the antioxidant activity of eel (Monopterus albus) extracts that live in the waters of the province of Jambi. Free radicals tend to cause chain reactions that occur in the body and will cause ongoing and continuous cell damage, especially in chronic diseases such as diabetes, hypertension and hypercholesterolemia. Prevention can be done by providing antioxidants, one of which is amino acids. In the Koran, it is stated that the carcasses that are lawful to eat are fish and grasshoppers. Eel is a type of fish that has a high albumin content. The eel meat sample that has been filled and given from its head, is cut into small pieces with a size of 1.5 cm2 and wrapped in a thin cloth in a container, then steamed, pressed, and centrifuged. the air and oil phases are taken and the impurities are removed by filtering, then they are dried using freeze drying in order to obtain the eel extract in powder form. The method used in this study is the Radical Scavenging Method using the chemical compound DPPH (2,2- diphenyl-1-pikrilhidrazil). From the research results it was found that the IC50 value of eel extract was 29.0816 ppm. Eel extract has the potential to ward off free radicals with strong activity.
