Every year, thousands of tons of fruit seeds are discarded as agro-industrial by-products around the world. Fruit seeds are an excellent source of oils, monounsaturated fatty acids, and n-6 and n-3 polyunsaturated essential fatty acids. This study aimed to develop a novel technology for extracting active substances from selected seeds that were obtained after pressing fruit juices. The proposed technology involved sonification with the use of ethyl alcohol at a low extraction temperature. Seeds of four species—blueberry (Vaccinium myrtillus L.), raspberry (Rubus idaeus), cranberry (Vaccinium macrocarpon), and cuckooflower (Cardamine pratensis)—were used for extraction. Following alcohol evaporation under nitrogen, the antioxidant activity, chemical composition, and volatile compounds of the obtained extracts were analyzed using chromatographic methods, including gas chromatography (GC)–mass spectrometry (MS) (GC–MS/MS), and high-performance liquid chromatography–MS. We analyzed physicochemical properties, fatty acid, and volatile compounds composition, sterol and tocochromanol content of blueberry, cranberry, raspberry, and cuckooflower seed oils obtained by sonication. This method is safe and effective, and allows for obtaining valuable oils from the seeds.
Antioxidant, Antimicrobial Activities and Fatty Acid Compositions of Wild Berberis spp. by Different Techniques Combined with Chemometrics (PCA and HCA)
Authors: Gıdık Betül
Published: December 2021

Interest in medicinal plants and fruits has increased in recent years due to people beginning to consume natural foods. This study aims to investigate the total phenolic flavonoid content, antioxidant activity, condensed tannin content, oil content, and fatty acid compositions of five local breeds of Berberis spp. from Bayburt, Turkey, and their antioxidant and antimicrobial activities. The fatty acid composition of samples was performed with gas chromatography-mass spectrometry (GC-MS), and the total fatty acid content of samples was between 6.12% and 8.60%. The main fatty acids in Berberis spp. samples were α-linolenic acid (32.85–37.88%) and linoleic acid (30.98–34.28%) followed by oleic acid (12.85–19.56%). Two antioxidant assays produced similar results, demonstrating that extracts of wild B. vulgaris L. had the highest ferric reducing antioxidant power (FRAP) (621.02 μmol FeSO4.7H2O/g) and 1,1-diphenyl-2-picrylhydrazyl radical (DPPH) (0.10 SC50 mg/mL) values. According to principal component analysis (PCA), four components were determined. In addition, two main groups were determined according to hierarchical cluster analysis (HCA), and wild and culture of B. vulgaris L. were in different subgroups. This is the first original report about the fatty acid composition and oil content of Berberis spp. grown in Bayburt, Turkey. The obtained results indicate that B. integerrima Bunge and B. vulgaris, which have especially remarkable fatty acid content, antioxidant, and antimicrobial activity, could be potential sources for these properties in different areas of use.
Development of a Wireless Corrosion Detection System for Steel-Framed Structures Using Pulsed Eddy Currents
Authors: Ha Namhoon , Lee Han-Seung , Lee Songjun
Published: December 2021

Structural health monitoring (SHM) can be more efficient with the application of a wireless sensor network (WSN). However, the hardware that makes up this system should have sufficient performance to sample the data collected from the sensor in real-time situations. High-performance hardware can be used for this purpose, but is not suitable in this application because of its relatively high power consumption, high cost, large size, and so on. In this paper, an optimal remote monitoring system platform for SHM is proposed based on pulsed eddy current (PEC) that is utilized for measuring the corrosion of a steel-framed construction. A circuit to delay the PEC response based on the resistance–inductance–capacitance (RLC) combination was designed for data sampling to utilize the conventional hardware of WSN for SHM, and this approach was verified by simulations and experiments. Especially, the importance of configuring sensing modules and the WSN for remote monitoring were studied, and the PEC responses caused by the corrosion of a specimen made with steel were able to be sampled remotely using the proposed system. Therefore, we present a remote SHM system platform for diagnosing the corrosion condition of a building with a steel structure, and proving its viability with experiments.
Complex-Valued Phase Transmittance RBF Neural Networks for Massive MIMO-OFDM Receivers
Authors: Soares Jonathan Aguiar , Mayer Kayol Soares , de Castro Fernando César Comparsi , Arantes Dalton Soares
Published: December 2021

Multi-input multi-output (MIMO) transmission schemes have become the techniques of choice for increasing spectral efficiency in bandwidth-congested areas. However, the design of cost-effective receivers for MIMO channels remains a challenging task. The maximum likelihood detector can achieve excellent performance—usually, the best performance—but its computational complexity is a limiting factor in practical implementation. In the present work, a novel MIMO scheme using a practically feasible decoding algorithm based on the phase transmittance radial basis function (PTRBF) neural network is proposed. For some practical scenarios, the proposed scheme achieves improved receiver performance with lower computational complexity relative to the maximum likelihood decoding, thus substantially increasing the applicability of the algorithm. Simulation results are presented for MIMO-OFDM under 5G wireless Rayleigh channels so that a fair performance comparison with other reference techniques can be established.
A Novel Hybrid NN-ABPE-Based Calibration Method for Improving Accuracy of Lateration Positioning System
Authors: Petrović Milica , Ciężkowski Maciej , Romaniuk Sławomir , Wolniakowski Adam , Miljković Zoran
Published: December 2021

Positioning systems based on the lateration method utilize distance measurements and the knowledge of the location of the beacons to estimate the position of the target object. Although most of the global positioning techniques rely on beacons whose locations are known a priori, miscellaneous factors and disturbances such as obstacles, reflections, signal propagation speed, the orientation of antennas, measurement offsets of the beacons hardware, electromagnetic noise, or delays can affect the measurement accuracy. In this paper, we propose a novel hybrid calibration method based on Neural Networks (NN) and Apparent Beacon Position Estimation (ABPE) to improve the accuracy of a lateration positioning system. The main idea of the proposed method is to use a two-step position correction pipeline that first performs the ABPE step to estimate the perceived positions of the beacons that are used in the standard position estimation algorithm and then corrects these initial estimates by filtering them with a multi-layer feed-forward neural network in the second step. In order to find an optimal neural network, 16 NN architectures with 10 learning algorithms and 12 different activation functions for hidden layers were implemented and tested in the MATLAB environment. The best training outcomes for NNs were then employed in two real-world indoor scenarios: without and with obstacles. With the aim to validate the proposed methodology in a scenario where a fast set-up of the system is desired, we tested eight different uniform sampling patterns to establish the influence of the number of the training samples on the accuracy of the system. The experimental results show that the proposed hybrid NN-ABPE method can achieve a high level of accuracy even in scenarios when a small number of calibration reference points are measured.
ARTFLOW: A Fast, Biologically Inspired Neural Network that Learns Optic Flow Templates for Self-Motion Estimation
Authors: Layton Oliver W.
Published: December 2021

Most algorithms for steering, obstacle avoidance, and moving object detection rely on accurate self-motion estimation, a problem animals solve in real time as they navigate through diverse environments. One biological solution leverages optic flow, the changing pattern of motion experienced on the eye during self-motion. Here I present ARTFLOW, a biologically inspired neural network that learns patterns in optic flow to encode the observer’s self-motion. The network combines the fuzzy ART unsupervised learning algorithm with a hierarchical architecture based on the primate visual system. This design affords fast, local feature learning across parallel modules in each network layer. Simulations show that the network is capable of learning stable patterns from optic flow simulating self-motion through environments of varying complexity with only one epoch of training. ARTFLOW trains substantially faster and yields self-motion estimates that are far more accurate than a comparable network that relies on Hebbian learning. I show how ARTFLOW serves as a generative model to predict the optic flow that corresponds to neural activations distributed across the network.

Una experiencia de responsabilidad social ambiental en la Universidad Metropolitana del Ecuador
Authors: Luque Espinosa de los Monteros Margarita Del Pilar
Published: December 2021

Aplicar responsabilidad social ambiental universitaria a través de proyectos de reciclaje constituye una experiencia muy valiosa para desarrollar la conciencia ambiental en estudiantes y docentes. El trabajo presentado es el resultado de un proyecto realizado entre la Universidad Metropolitana del Ecuador y dos instituciones educativas de la provincia del Guayas. Se utilizaron métodos teóricos y empíricos en la investigación. Se encontró que, aunque el marco legal de Ecuador concibe la educación ambiental como un aspecto de suma importancia, no siempre se le da la prioridad que requiere, muchas veces los docentes que deben guiar esta actividad la descuidan o desconocen sobre el tema. Se concluye que para poder formar una conciencia ambiental desde los ejes transversales se requiere de un alto dominio pedagógico y didáctico por parte de los docentes, y una conciencia de la importancia de abordar esta necesidad educativa.

A indústria naval brasileira enfrenta novos desafios no gerenciamento de sua produção, a alta competitividade, no contexto internacional, levou estaleiros brasileiros a descontinuar suas atividades. O sistema Lean Manufacturing é um modelo de gestão que prevê protocolos em toda a cadeia de produção a fim de aumentar a produtividade e, ao mesmo tempo, a reduzir desperdícios. Por essa razão, o objetivo desse trabalho é investigar qual é o grau de aderência ao Lean Manufacturing por parte de estaleiros de grande porte em atuação no Brasil. Para esta pesquisa de caráter qualitativo, primeiramente foi realizada uma entrevista, por meio de um questionário, com gestores dos Estaleiros A (Pernambuco) e B (Rio Grande do Sul). Tal procedimento teve como base as normas SAE J4000 (identificação e adesão de práticas mais efetivas numa operação enxuta) e SAE J4001 (manual para a implementação de uma operação enxuta). Posteriormente, foi realizada uma análise das respostas dos entrevistados. A partir dos dados coletados e da análise feita em cada elemento, o grau de aderência ao sistema Lean do estaleiro B foi de 20,26%, o que o caracteriza no Nível 0 da Norma J4001 e no estaleiro A, o grau de aderência ficou em 61,36%, o que o caracteriza como nível 2 da referida norma. Esse resultado se dá pelo motivo do Estaleiro A está há mais tempo com a cultura Lean implementada. Desse modo, a metodologia Lean demonstrou ser efetiva na busca por mais produtividade e menos prejuízos no setor naval, com pessoas engajadas e preparadas dentro da filosofia Lean, porém é indispensável o comprometimento da alta gerência ao longo de todo o processo, visto que embora a implementação cause um evidente impacto nos resultados, existe uma necessidade de manutenção contínua dos conceitos do Lean para todos os níveis da organização.

On the Ground, Documents on My (Pandemic) Walks
Authors: Latham Kiersten
Published: December 2021

The pandemic has led us to a multitude of activities we have not done before. For me, this included hour-long walks around my new neighborhood every day, rain or shine. Before the pandemic, my “walks” were directed, as my goal was to get to work, not “have a walk.” Now, these walks are an integral part of my thinking—to both clear my mind and to learn. I listen to podcasts, audiobooks, and sometimes nothing at all. I have taken to very intentional looking on my walks, noticing the details on the houses, dreaming of what they might look like on the inside, watching the weather change and the plant life die and emerge again. I have also been noting the signs that pop up from my unknown neighbors in the form of yard signs, chalk drawings, flags with notes, unintended detritus, snowmen (and women) and artworks. I look down a lot now as well. I notice what is at my feet. I am endlessly fascinated with sidewalk documents. The obvious ones are wonderful, such as children’s drawings and little fairy (and dinosaur) scenes. But the cement stamps have really captured my attention. What stories do these sidewalks have to tell? What follows is a set of collages, documentation of documents I found on the ground during my pandemic walks—from the plant world, to the fairy world, to the seemingly mundane world of cement pouring. What emerged became a colorful and telling assortment of stories, both made up and real.

A text analysis was performed to identify the most frequently occurring n-grams present in the corpus of tweets. Thematic analysis and sentiment analysis were used to categorize the tweets. The transcript of the Rose Garden press conference remarks was separately analyzed using the same techniques.
Storm Warnings: Time Sensitive Proximity
Authors: Boettcher Carrie , Bonnici Laurie , O'Connor Brian
Published: December 2021

Weather-predictive tasks during high risk severe weather events are carried out for the common good of the community by virtual teams of weather professionals. Severe weather predictors are responsible for producing the early warnings that inform people in harms way and potentially save lives. Should we be concerned with the use of “other-generated” information from social media used by these professionals? Teams extend understanding of an event by looking to external sources of situationally relevant information such as storm spotters, publicly generated photos and comments posted to online social media (OSM), and communication with community partners. Situationally relevant OSM, specifically Twitter, provides insight to the information behavior of the team. Here we examine the role of proximity and how it impacts decisions on potentially life-saving information sharing in time sensitive information environments: proximity within the team (shared knowledge state) and proximity to the event (hashtag) specifically are addressed.
Commuters’ Health Certificate as Social Control during the COVID-19 Pandemic
Authors: Suprayitno  , Rahmi  , Christiani Lydia
Published: December 2021

In Indonesia, a regulation on large-scale social restrictions (“Pembatasan Sosial Berskala Besar” or PSBB) restricted citizens’ activities in the cultural, social, and economic sectors. These large-scale social restrictions also impact Jakarta’s activities from the commuting communities of Central Java, the Yogyakarta Special Region, and East Java Provinces. As a result, these commuters have become accustomed to travelling back to their hometowns every Friday afternoon. On Sundays, they return to Jakarta and arrive in Jakarta on Monday mornings to go to work. This activity is often referred to as “Pulang Jumat Kembali Ahad” (PJKA) or Going Home Every Friday Evening and Returning on Sunday. This paper then aims to examine the experience of PJKA actors during the crisis from the lens of document theory. The function of a health certificate free of COVID-19 is examined similarly to the function of a passport as a condition for entering the country. A sheet of health certificate free of COVID-19 is a derivative of the presidential regulation and the minister of transportation regulation, impacting documentality characteristics.
Documents in the Dynarchive: Questioning the Total Revolution of the Digital Archive
Authors: Pierce Rachel
Published: December 2021

The digital archive is often described in opposition to its physical counterpart. Media theorist Wolfgang Ernst has coined the term “dynarchive” to describe the former, a phrase that neatly contrasts digital archival remixability with the statis of the physical archive and its hierarchical fond structure. The article both uses and questions this characterization by examining the archive’s physical and digital document practices in three areas: (1) Hierarchical collection description versus individual document description; (2) Original order versus relevance-based results; and (3) Archival selection practices and the illusion of completeness. Archival structure and description have been central to the authority and evidentiary value of archival documents. Yet both the market logics of the internet and criticism from historically oppressed groups have challenged these connections. Using the dynarchive as a conceptual frame, this article examines archival digitization's potential for decolonization of the archive via its fragmentation into a non-hierarchical web of interrelated documents.
Diario de una futbolista que nunca fue: historias de mujeres, deseos de gol y saberes compartidos en las canchas desniveladas de Pehuajó
Authors:   , Molejón Amanda
Published: December 2021

Este trabajo, aún con este formato irreverente pretende visibilizar modos de ser y hacer mujeres en una práctica deportiva atravesada por la masculinidad hegemónica como lo es el fútbol. Las protagonistas centrales son Las Pibas y La Profe, mujeres jóvenes que juegan al fútbol de manera sistemática en el playón del barrio; y más tarde también en un club de la ciudad de Pehuajó. Lo educativo es mirado en clave de género, en un intento por visibilizar modos de enseñanza y aprendizaje alrededor del ser mujeres que reproducen y tensionan normas de género. La investigación se enmarca en los estudios de las mujeres y géneros, utilizándose como enfoque metodológico la etnografía feminista. Como en todo lo propuesto desde los feminismos lo personal es político, por eso la escritura en este formato tipo diario: modo muy habitual de organización de los escritos de mujeres, poco frecuente en la academia.

Reflections on Science at the Interface of the Islamization of Knowledge Debate
Authors: Kirmani M. Zaki
Published: December 2021

The author revisits the forty-year Islamization of knowledge debate in relation to science. He maintains that values and the worldview have an undeniable role in science and its multidimensional growth. He maintains that the role of values in science is no more controversial, and if some people still deny it, it may not be long before they will reverse and reframe their opinion on the relation between science and religion.
The Ethics of Wasaṭīyah and the Pursuit of Gender Equality
Authors: Anwar Etin
Published: December 2021

The paper deals with the concept of wasaṭīyah (moderation) as an ethical framework for community making and its impact on the pursuit of gender equality. Qur’an 2:143 speaks about the correlation between making a fair community (al-ummah al-wasaṭ) and piety, which is inclusive of both men and women. As both terms are intertwined, any efforts to discuss wasaṭīyah must include how Muslims relate to God and how this relationship is exercised in all areas of their lives. Given that this intersection is a matter of ethics, my paper will demonstrate that wasaṭīyah affords the inclusion of both genders as ethical agents in the pursuit of a fair community. I first discuss how the ethics of wasaṭīyah provide a framework for community building by drawing some parallels between Prophet Muhammad’s creation of a fair and inclusive community and how Muslims could embody God’s message within themselves and their communities. I then show how including women in the community-making process echoes both the Islamic ethics of moderation and the value of women as ethical agents.
Making Africa Legible
Authors: Bolton Caitlyn
Published: December 2021

European colonialism and missionization in Africa initiated a massive orthographic shift across the continent, as local languages that had been written for centuries in Arabic letters were forcibly re-written in Roman orthography through language standardization reforms and the introduction of colonial public schools. Using early missionary grammars promoting the “conversion of Africa from the East,” British colonial standardization policies and educational reforms, as well as petitions and newspaper editorials by the local Swahilispeaking community, I trace the story of the Romanization of Swahili in Zanzibar, the site chosen as the standard Swahili dialect. While the Romanization of African languages such as Swahili was part of a project of making Africa legible to Europeans during the colonial era, the resulting generation gap as children and parents read different letters made Africa more illegible to Africans themselves.
