Published: February 2025

Introduction
The purpose of this study was to evaluate the long-term clinical results (minimum 20 years) the ultra-short anatomic cementless stem in patients < 50 years of age.
Materials and Methods
We reviewed the 336 patients (421 hips) who had a cementless total hip arthroplasty (THA) in patients < 50 years (46 ± 3 years) at the time of surgery. The most common diagnoses were osteonecrosis (47%) and developmental dysplasia (37%). Demographic data, the Harris hip score, Western Ontario and McMaster Universities Osteoarthritic Index (WOMAC), and the University of California, Los Angeles (UCLA) activity scores were recorded. The minimum follow-up interval was 20 years (mean, 21.5 years; range, 20 to 24 years).
Results
At the time of final follow-up, the mean Harris hip score, WOMAC score, and UCLA activity score were 93 points, 15 points, and 8 points, respectively. All but 7 patients had no thigh pain at the final follow-up. Seven hips (1.7%) had aseptic loosening of the stem. Survival rate at 24 years after the operation was 99.1% for the acetabular component and 96.4% for the femoral component.
Conclusions
These results in patients < 50 years of age suggest that this calcar loading with lateral flare anatomic cementless hip prosthesis provides good long-term fixation. Moreover, the alumina ceramic-on-alumina ceramic bearing provides a high rate of survivorship without osteolysis.
Plastic Pollution, Political Economy, and Policy Failure: Investigating the Implementation Barriers of Section 6A in the Bangladesh Environmental Conservation Act, 1995

Published: February 2025

In 2002, Bangladesh became the first country to implement a ban on the use of polyethene bags. However, after 20 years, the ban has not been implemented. Hence, this study investigates the political and economic barriers to implementing the polyethene bag ban in Bangladesh. Moreover, this study employed a multi-faceted methodology to investigate plastic pollution and management strategies comprehensively. This study collected secondary data through a comprehensive review of several fundamental documents, including national policies and international frameworks. Moreover, face-to-face key informant interviews and an online survey captured diverse perspectives. This study found that the low pricing of polythene bags, the lack of alternatives to polythene bags, the high price of alternatives, and the lack of financial and infrastructural support for eco-friendly alternatives are the main economic barriers to polyethene bag bans. Notably, 91 participants (57.90%) think that the lack of cheaper alternatives, such as polyethene bags, is the main barrier to implementing the ban in Bangladesh. The results also indicated that cheaper prices (22%), easy availability (36%), and high prices of alternatives (27%) were the main reasons for participants preferring polyethene bags. The finding of this study is that a cheaper and more environmentally friendly alternative is needed in our country to implement the ban successfully. Additionally, the public and private sectors should come forward to invest in the alternative bag sector to make it cheaper for consumers. The government's initiatives, while commendable, necessitate stringent enforcement, amendments for specificity, and expansion beyond Dhaka to ensure holistic efficacy. The central government's role in influencing plastic waste management through taxation and incentives is pivotal, requiring the alignment of NGOs and civil society to foster public awareness and collaboration. This comprehensive examination serves as a foundation for informed policymaking and sustainable interventions to address Bangladesh's pressing challenges with plastic waste.
Ecological and Physicochemical Determinants of Freshwater Snail Prevalence, Density, and Schistosome Infection in the Lango Subregion, Northern Uganda: Implications for Disease Control

Published: February 2025

Background Freshwater snails serve as intermediate hosts for trematodes that cause human and animal diseases, notably schistosomiasis and fascioliasis. In Uganda’s Lango subregion, schistosomiasis remains endemic, yet the ecological and physicochemical factors influencing snail prevalence, density, and infection remain poorly understood. This study investigated these factors to inform targeted disease control strategies.
Methods A cross-sectional study was conducted in the Lira and Kole districts during the dry and rainy seasons of 2023. Snails were collected from streams, ponds, swamps, and rice paddies by handpicking and scooping methods. Morphological identification and cercarial shedding tests were performed to determine the species composition and infection status. Physicochemical water parameters, including pH, salinity, dissolved oxygen (DO₂), total dissolved solids (TDS), and temperature, were measured. Generalized linear models were used to assess the predictors of snail prevalence and density.
Results A total of 4,802 snails from 13 species were collected, with Biomphalaria (47.2%) and Bulinus(23.7%) being the most abundant genera. The snail density was greater in the rainy season (53.7%) than in the dry season (46.3%). Among the 3,404 Biomphalaria and Bulinus snails examined, 0.15% were infected with schistosome cercariae, including Biomphalaria sudanica (0.03%), B. choanomphala(0.06%), and Bulinus africanus(0.06%). Logistic regression analysis revealed that salinity, TDS, conductivity, water depth, and DO₂ significantly influenced snail prevalence, explaining 73.1% of the variation in B. sudanica and 82.2% in B. choanomphala. Negative binomial regression (Table 3) indicated that water temperature, TDS, pH, and anthropogenic activities affected snail density. Lymnaea natalensis and B. choanomphala thrived in habitats with moderate DO₂ values and human activities such as washing and bathing, whereas car washing negatively impacted density.
Conclusions This study highlights the role of ecological and physicochemical factors in freshwater snail distribution, density, and infection rates. These findings provide critical insights for targeted snail control interventions, including habitat modification, improved sanitation, and seasonal mass drug administration, to mitigate schistosomiasis transmission in the Lango subregion and nationwide.
Further validation of a mixed convection model of tunnel critical velocity against fullscale experimental data
Authors: Beyer Michael , Stacey Conrad , Brenn Günter
Published: February 2025

This short note adds further data to the assessment of the Beyer Stacey Brenn mixed convection model for estimating the critical velocity to prevent smoke backlayering in tunnels [1]. The additional data are full-scale test data from the Memorial Tunnel fire tests where the false ceiling was in place, and the longitudinal flow was generated by point supply of fresh air or point extraction of air/smoke. The data have greater uncertainty than those from later Memorial Tunnel tests with a high arched ceiling, and that may be why the later data on critical velocity were separately published and preferred by previous authors. Within the uncertainty in the earlier data, they agree with predictions from the Beyer Stacey Brenn critical velocity model [1].
Observation-based probabilistic reanalysis of storm surge and sea level extremes for the United States

Published: February 2025

Reliable probabilistic estimates of storm surge and sea level extremes at gauged and ungauged locations with robust uncertainty quantification are key for successful risk assessment and cost-effective adaptation, now and in the future. However, existing observational estimates are often unavailable or uncertain along most coastal regions because of data scarcity. Here, we provide a fully observational-driven probabilistic dataset of storm surge extremes for the U.S. coastline covering 1950–2020. Non-stationary extreme storm surge distributions at gauged and ungauged sites are estimated by analyzing the U.S. hourly tide gauge data network using a spatiotemporal Bayesian Hierarchical Model. In addition, an extended version of such dataset is also produced where many additional storm events are incorporated to account for key extremes not contained in standard tide gauge records. The resulting distributions are combined with deterministic tidal data to estimate return periods of extreme sea levels and their uncertainty. Comparisons against published estimates are provided indicating that storm surge and sea level extremes along most U.S. coast have been underpredicted. The data provided can support coastal managers to make more confident decisions, particularly along many U.S. coastal regions that are vulnerable and where long-term in-situ water level monitoring is limited or non-existent.
Optimizing Dual Wideband Microstrip Bandpass Filters: A Genetic Algorithm Approach with Transmission Line Modelling
Authors: Singh Aditya , Singh Ritika , Jangid Ashok
Published: February 2025

This paper provides a framework for an intelligent design methodology for a dual-band bandpass filter (DB-BPF), utilising a modified genetic algorithm (GA) approach for enhanced efficiency and accuracy over traditional GA techniques. In this design, the electrical parameters optimized using a variation of conventional GA. To expedite and refine the optimisation process, a transmission line model is employed to compute the fitness values during the GA process. For demonstrating the utility of the method, a dual-band bandpass filter with frequencies 2.2 GHz and 5 GHz (fractional bandwidth 63.6% and 36% respectively achieved) has been designed. The optimized design is confirmed using full-wave methods such as the Method of Moments (MoM) and electromagnetic (EM) simulation via CST software. The prototype circuit size of the dual-band bandpass filter is only about 0.34λg × 0.20λg. The predicted and simulated results verify the effectiveness of the proposed method, demonstrating high efficiency and superior in-band and out-of-band performance.
Inhibition of Enzymatic Browning and Antioxidant Activities of Marrubium vulgare L Extracts: A Promising Natural Solution
Authors: Tighilet Karim , Abdelaziz Messis , Ahmed Adjebli
Published: February 2025

In recent decades, medicinal plants have attracted significant interest due to their demonstrated therapeutic properties. This study analyzed different extracts of Marrubium vulgare L. (horehound) to assess their phytochemical composition and biological activities. Quantitative analysis revealed that methanolic leaf extracts were the richest in polyphenols, containing 23.48 to 35.36 mg EAG/g DM. These leaf extracts also had a particularly high flavonoid content, ranging from 12.55 ± 0.233 to 20.56 ± 0.54 mg EQ/g DM. In contrast, aqueous stem extracts were abundant in condensed tannins, with 72.82 ± 0.772 and 65.52 ± 1.216 mg EC/g DM in aqueous and methanolic extracts, respectively. The antioxidant potential of the extracts was evaluated through several in vitro assays. Leaf extracts demonstrated the highest antioxidant activity, with methanolic extracts exhibiting stronger antioxidant capacity than aqueous extracts. Furthermore, leaf extracts were capable of inhibiting peroxidase activity by up to 42.68%, although they showed weak inhibition of polyphenol oxidase. These findings suggest that Marrubium vulgare L is a promising source of natural antioxidants and enzyme inhibitors, with potential applications in the development of functional foods, cosmetics, and pharmaceuticals. The observed differences between extraction solvents highlight the importance of considering phytochemical profiles and bioactivities when selecting and optimizing plant-based ingredients.

Hochschulen zwischen künstlicher Intelligenz und möglichen Zukünften
Authors: Höfler Elke
Published: February 2025

In der von Volatilität, Unsicherheit, Komplexität und Ambiguität geprägten VUCA-Welt intensiviert die fortschreitende Entwicklung von Künstlicher Intelligenz (KI) sowohl die bestehenden Herausforderungen als auch die Chancen, indem bestehende Strukturen destabilisiert und Unsicherheiten verstärkt werden. Ein zentraler Schlüssel, diesen Dynamiken erfolgreich zu begegnen, liegt in der gleichzeitigen Entwicklung von AI Literacy und Futures Literacy. AI Literacy befähigt dazu, KI-Technologien kompetent und kritisch zu nutzen; Futures Literacy hingegen unterstützt das Antizipieren möglicher Zukünfte und das Entwickeln kreativer, resilienzfördernder Handlungsoptionen. Beide Kompetenzen müssen gemeinsam gedacht, gefördert und strategisch miteinander verknüpft werden, um langfristig sinnvolle Entscheidungen zu ermöglichen.
Dieser Beitrag stellt sieben methodische Ansätze vor, die die Entwicklung dieser Kompetenzen unterstützen können. Die vorgestellten Methoden sollen zukünftig einer empirischen Fundierung unterzogen werden, um ihre Wirksamkeit und Relevanz im Hochschulkontext zu überprüfen. Ziel ist es, evidenzbasierte Bildungsstrategien zu entwickeln, die Lernende dazu befähigen, sich in einer sich dynamisch wandelnden Welt selbstbestimmt und erfolgreich zu orientieren.

Measuring the Contributions of Vision and Text Modalities
Authors: Parcalabescu Letitia
Published: February 2025

This dissertation investigates multimodal transformers that process both image and text modalities together to generate outputs for various tasks (such as answering questions about images). Specifically, methods are developed to assess the effectiveness of vision and language models in combining, understanding, utilizing, and explaining information from these two modalities. The dissertation contributes to the advancement of the field in three ways: (i) by measuring specific and task-independent capabilities of vision and language models, (ii) by interpreting these models to quantify the extent to which they use and integrate information from both modalities, and (iii) by evaluating their ability to provide self-consistent explanations of their outputs to users.
ЗРЕНИЕ И ЗНАНИЕ В ФИЛОСОФИИ АРИСТОТЕЛЯ
Authors: АВАНЕСОВ С.С.
Published: February 2025

В этой статье я продолжаю изучение проблемы зрения в его отношении к философскому постижению истины в античности. Здесь я анализирую тему соотношения знания и зрения в философском мышлении Аристотеля. Я прихожу к выводу о том, что в философии Аристотеля присутствует очевидная тенденция оптического понимания процесса постижения сути сущего как её усматривания; представление о знании как видении указанной сути (истины) и о знающем как видящем реальное положение дел; учение о практической ориентации благого действия как созерцании конечной цели «оком души».

In this article, I continue to study the problem of vision in connection with philosophical comprehension of truth in antiquity. I analyze the topic of the relation between knowledge and vision in the philosophical thought of Aristotle. I come to the conclusion that in Aristotle’s philosophy there is an obvious trend of optical understanding of the process of comprehension of the essence of being as a sight of its essence; the idea of ??knowledge as a vision of the truth and the notion of a knowledgeable person as the one who sees the real state of affairs; the doctrine of practical orientation of a good action as a contemplation of the ultimate goal by “eye of the soul”.

КТО К КОМУ ИДЕТ НА ПИР, ИЛИ О "ПОРЧЕ" ПОСЛОВИЦ В ПЛАТОНОВСКОМ "ПИРЕ" (SMP. 174A3-C7)
Authors: ПРОТОПОПОВА И.А.
Published: February 2025

В статье анализируется смысл фрагмента в начале платоновского диалога «Пир», где Сократ переиначивает («портит») поговорку о «благих, идущих на пир без приглашения» ( Smp. 174a3-c7). Автор кратко указывает на связанные с этой поговоркой текстологические проблемы и отмечает как минимум два ее варианта, бытовавших во времена Платона. Основное внимание в статье уделяется двум вопросам: 1) какой вариант поговорки и как именно искажает Сократ и, по его словам, Гомер? 2) какой смысл, прежде всего философский, можно обнаружить в этом фрагменте в контексте всего диалога? Автор предлагает свою интерпретацию исходя из представления о том, что лейтмотивом диалога является тема гибриса в контексте инверсии: при этом «перевертыши» касаются как игры слов, так и «оборотничества» в действиях персонажей, прежде всего Сократа. Рассматривая функции ключевых для данного фрагмента слов διαφθείρω, μεταβάλλω, ὑβρίζω в «Пире» и других диалогах Платона, автор показывает, как эта тема преломляется в «философско-эротической» семантике «Пира», тесно связанной здесь с диалектикой.

The article analyzes the meaning of a passage from Plato's dialogue Symposium, where Socrates modifies ("spoils") the proverb about “the good ones”, who go to the feast without an invitation (Smp. 174a3-c7). The author indicates the textual problems related to this proverb and notes at least two versions of it in existence in Plato's time. The main attention is paid to these two questions: 1) which version of the proverb and how exactly does Socrates distort, and, according to him, also did Homer? 2) what point, above all a philosophical one, may be traced in this passage, given the context of the dialogue as a whole? The author offers her own interpretation based on the view that the leitmotif of the dialogue is the theme of ????? put in terms of inversion (including turns and reversals in wordings and actions of the characters, Socrates above all. Appraising the functions of this passage's keywords, ?????????, ?????????, and ??????, in the Symposium and other dialogues of Plato, the author shows how this theme is reflected in a "philosophical-erotic" semantics of the Symposium, which is closely associated here with dialectics.
ДЕСКРИПТИВНЫЙ И АСКРИПТИВНЫЙ ПОДХОДЫ К ОБЪЯСНЕНИЮ ДЕЙСТВИЯ
Authors: ОГЛЕЗНЕВ В.В.
Published: February 2025

В статье рассматриваются различные подходы к объяснению действия. Показано влияние теории действия Аристотеля на формирование современной философии действия, представленной, прежде всего, редукционистской и каузалисткой концепциями, объясняющие действие преимущественно в дескриптивных терминах. Доказано, что отрицание физического и психологического компонентов действия позволяет прийти к следующим выводам, во-первых, действие является социальным понятием и логически зависит от принятых правил поведения, во-вторых, по характеру оно существенно не дескриптивно, но аскриптивно, и, в-третьих, оно представляет собой понятие, определяемое посредством исключений, а не посредством множества необходимых и достаточных условий, физических или же психологических.

This essay is concerned with different approaches to the elucidation of action. It explicates the influence of Aristotle’s theory of action on the development of the modern philosophy of action, provided, first of all, by Reductionist and Causalist’s points of view. The author argues that the denial of the physical and psychological components of the action allows to conclude, firstly, that action is a social concept, logically dependent on the accepted rules of conduct; secondly, that it is fundamentally not descriptive, but ascriptive in its character; and thirdly, that it is a defeasible concept to be defined through exceptions and not by a set of necessary and sufficient conditions whether physical or psychological.
ПАРМЕНИДОВСКИЕ ПРЕДПОСЫЛКИ В HOMOMENSURA ПРОТАГОРА
Authors: БЕРЕСТОВ И.В.
Published: February 2025

Мы показываем, что Протагор мог обосновывать свой тезис homo mensura с использованием двух положений, восходящих к Пармениду. Первое положение утверждает, что сложный (целый) интенциональный объект постигается только «весь сразу», а не по частям. Второе положение утверждает, что интенциональный акт тождественен своему содержанию. Из этих двух положений можно вывести, что различные интенциональные акты всегда направлены на различные интенциональные объекты. Это является даже более радикальным тезисом, чем традиционно приписываемый Протагору «релятивизм истины»: пропозиция истинна если и только если она присутствует в системе убеждений субъекта. В конце статьи мы показываем, что не только homo mensura может интерпретироваться как следствие указанных положений Парменида, но и некоторые положения Горгия тоже могут рассматриваться подобным же образом.

We show that Protagoras could prove his homo mensura thesis by means of two statements ascending to Parmenides. The first statement asserts that any complex (or whole) intentional object can be grasped only “all at once”, and not part by part. The second statement asserts that any intentional act is identical to its content. We can deduce from these two statements that any different intentional acts are always directed to different intentional objects. This is even more radical thesis than “relativism about truth”, which is traditionally ascribed to Protagoras: any proposition is true iff it belongs to the subject’s system of believes. In conclusion, we show that not only the homo mensura thesis can be interpreted as a consequence of the above provisions of Parmenides, but certain Gorgias’ statements can also be considered in a similar way.
КАРТА ПТОЛЕМЕЯ И АНТИЧНЫЕ ПЕРИПЛЫ
Authors: ЩЕГЛОВ Д.А.
Published: February 2025

Карта Птолемея впервые сопоставляется с данными античных периплов о протяжённости береговой линии. В результате между ними отмечаются многочисленные близкие совпадения, указывающие на то, что карта Птолемея опиралась на сведения аналогичных периплов в значительно большей степени, чем это допускалось ранее. В дополнение прослеживается, какое влияние на карту Птолемея оказала заниженная оценка окружности Земли, которую он положил в её основу, а именно отмечаются два типа искажений. Во-первых, вместе с окружностью Земли многие участки побережья, ориентированные с севера на юг, у Птолемея сокращаются в сравнении с данными периплов, что, во-вторых, компенсируется пропорциональным растяжением других участков, ориентированных с запада на восток. В частности, сделанные наблюдения дают простое объяснение необычной конфигурации Каспийского моря на карте Птолемея.

Ptolemy’s map is for the first time compared with the data on the length of the coastlines transmitted by ancient periploi. As a result, many close coincidences are traced between them, showing that Ptolemy’s map was much more heavily based on these or similar peripli than it has been assumed until now. Additionally, the influence of Ptolemy’s underestimated value for the circumference of the Earth on his map is revealed. Namely, two interrelated distortions are observed to result from this error. First, coasts oriented meridionally were compressed in comparison with the distances recorded in periploi. Second, this compression was compensated by proportional stretching of adjacent coasts oriented latitudinally. In particular, these findings suggest a simple explanation for the strange shape of the Caspian Sea on Ptolemy’s map.

Эта книга представляет собой новое направление в исследовании истории науки: анализ научного стиля письма в контексте литературного стиля соответствующего периода. Философское значение исследования состоит в том, что оно представляет новый способ осмысления понятия научного стиля. Впервые, эллинистической математический корпус - один из наиболее сохранившихся - помещен в контексте обсуждения эллинистической культуры в целом. Р. Нетц утверждает, что эллинистические математические труды исповедуют нарративную стратегию, заключающуюся в повествовательном удивлении, в композиционной форме мозаичности фрагментов, и карнавальной обильности деталей. Кроме того, Нетц утверждает, что такие стилистические предпочтения связаны со стилем эллинистической поэзии. Эта важная книга будет полезна всем интересующимся эллинистической цивилизацией, а также историкам античности и математики.

This book represents a new departure in science studies: an analysis of a scientific style of writing, situating it within the context of the contemporary style of literature. Its philosophical significance is that it provides a novel way of making sense of the notion of a scientific style. For the first time, the Hellenistic mathematical corpus - one of the most substantial extant for the period - is placed centre-stage in the discussion of Hellenistic culture as a whole. Professor Netz argues that Hellenistic mathematical writings adopt a narrative strategy based on surprise, a compositional form based on a mosaic of apparently unrelated elements, and a carnivalesque profusion of detail. He further investigates how such stylistic preferences derive from, and throw light on, the style of Hellenistic poetry. This important book will be welcomed by all scholars of Hellenistic civilization as well as historians of ancient science and Western mathematics.
The theory of ‘union–distinction’ as a paradigm of Gr. Palamas’ methodology
Authors: Tereziz CH. , PETRIDOU L.
Published: February 2025

The issue concerning the real existence of the divine energies and consequently their relation to the divine essence is remarkably important for Christian Metaphysics. This study deals with the way in which Gr. Palamas included in this perspective the theory on unions and distinctions, which derives from Pseudo-Dionysius the Areopagite’s works, who is considered to be one of the main founders of Christian theology. It is also important to mention that the study deals with matters that, on the one side, have formed a tradition in the history of Christianity and, on the other, are subsumed in the context of the hesychastic controversy of the fourteenth-century, during which the specification of both the similarities and the differences between philosophy and theology was decisively raised.
PERLINDUNGAN HUKUM TERHADAP PEKERJA MIGRAN INDONESIA DI HONGKONG ATAS TINDAKAN OVERCHARGING

Published: February 2025

Overcharging merupakan biaya penempatan berlebih yang dibebankan kepada pekerja migran Indonesia. Dalam Pasal 30 ayat 1 UU No. 18 dijelaskan bahwa pekerja migran Indonesia yang selanjutnya disebut PMI seharusnya tidak dibebani biaya penempatan. Berdasarkan amanat pasal tersebut ditetapkanlah Peraturan BP2MI No. 9 tahun 2020 tentang pembebasan biaya penempatan, namun peraturan tersebut hanya berlaku terhadap PMI yang belum pernah diberangkatkan. Bagi PMI yang pernah diberangkatkan masih dibebani biaya penempatan yang besarnya sesuai dengan negara penempatan. Hal tersebut yang menyebabkan masih maraknya praktik overcharging. Tindakan overcharging sering terjadi dikalangan pekerja migran Indonesia yang berada di Hongkong. Terdapat beberapa faktor yang memengaruhi pekerja migran Indonesia khususnya di Hongkong terkena tinakan overcharging. Pelaku overcharging dapat di kenai sanksi berupa penghentian sementara Sebagian atau seluruh kegiatan usaha penempatan PMI yang diatur dalam Permenaker nomor 7 tahun 2020. Dan bagi pelaku overcharging di Hongkong dapat di kenakan Pasal 53 ayat (1) huruf (c) angka (iv) Peraturan Ketenagakerjaan Hongkong dimana pelaku yang terbukti melakukan overcharging dapat dicabut izin usaha yang dimiliki pelaku tersebut. Oleh sebab itu penelitian ni berfokus terhadap perlindungan hukum yang didapat PMI Hongkog atas tindakan overcharging.
A VISÃO BASEADA NOS RECURSOS E O ESTUDO DO AMBIENTE INTERNO DA PRÓ-REITORIA DE EXTENSÃO, PESQUISA E INOVAÇÃO DO IFPR
Authors: Carli Celia , Hastenreiter Filho Horacio Nelson , Mellinger Larissa
Published: February 2025

O presente artigo tem como objetivo apresentar a investigação de como a disponibilidade dos recursos internos da Pró-reitoria de Extensão, Pesquisa e Inovação - PROEPI, unidade pertencente ao Instituto Federal de Educação, Ciência e Tecnologia do Paraná (IFPR) - afeta as ações relativas às áreas de Extensão, Pesquisa e Inovação. O estudo de caso desenvolvido teve como base teórica a Visão Baseada em Recursos - VBR, a qual enfatiza que as estratégias organizacionais podem ser formuladas a partir da disponibilidade de recursos e capacidades internos de cada organização. Foi utilizado o modelo teórico de avaliação de estratégia (Modelo de Grant, 1991), o qual sugere que a organização ao desenvolver estratégias para obtenção de novos recursos e competências, deve primeiro avaliar seu ambiente interno, os recursos e capacidades que têm disponível, para que sejam selecionados os recursos que servem de base para geração de competências. O procedimento permitiu identificar as principais forças e fraquezas da pró-reitoria e, ao mesmo tempo, situar a importância dos recursos internos e das competências das pessoas para a tomada de decisão quanto às futuras estratégias.
CONTRIBUIÇÕES DA CULTURA ORGANIZACIONAL NA GESTÃO DO PROCESSO DE INOVAÇÃO TECNOLÓGICA

Published: February 2025

As estratégias baseadas em inovação que façam uso de mecanismos para desenvolvimento e fomento da cultura organizacional podem representar a pedra angular para a orientação, o desenvolvimento criativo de inovações e soluções por parte dos funcionários de uma empresa. Diante do exposto, este trabalho apresenta relatos das empresas 3M e Natura que se revestem de culturas organizacionais pautadas na inovação para os mercados. Para tanto, procedeu-se uma pesquisa de natureza descritiva, cujo procedimento de coleta deu-se por meio de dados secundários. Para análise dos dados obtidos utilizou-se a abordagem de Schein (2014) que discute os níveis da cultura organizacional em artefatos, crenças e valores e pressupostos básicos. A partir dos resultados obtidos observou-se que no nível dos artefatos a 3M e a Natura apresentam procedimentos e ferramentas muito semelhantes sob o ponto de vista da formalização de processos robustos de gestão da inovação tecnológica e de rotinas de incentivo à inovação. Sob a perspectiva das crenças e valores das culturas organizacionais, nota-se que a 3M apregoa intensamente a busca por ideias para inovação, permitindo nesse processo a ocorrência (esperada) de erros e riscos. A Natura, por sua vez, é fortemente marcada pelo posicionamento da experiência com a sustentabilidade através de seus produtos pautados em conhecimento e inovação. Finamente, sob o ponto de vista dos pressupostos básicos das empresas, a 3M aponta que a sua razão de ser reside em solucionar problemas não solucionados de maneira inovadora. Já a Natura sinaliza que a sustentabilidade é uma meta de ação legítima do seu negócio.

O Sistema de Gerência de Pavimentos é atualmente uma importante ferramenta de gestão, pois determina a forma mais eficaz de aplicação dos recursos disponíveis, com isso, a avaliação do pavimento é utilizada para auxiliar na tomada de decisão e na otimização dos recursos. Com base nisso, é necessário desenvolver procedimentos simples, eficientes e confiáveis que forneçam dados válidos e de baixo custo sobre a condição dos pavimentos e que fortaleçam o controle de qualidade. Desta forma, este trabalho tem como objetivo analisar a correlação entre o Índice de Condição Atual dos Pavimentos e o Índice de Condição dos Pavimentos do Instituto do Asfalto na área urbana, bem como classificar e analisar a condição dos pavimentos. Para avaliar o estado geral da superfície do pavimento, foram utilizados o Índice de Condição dos Pavimentos segundo o Instituto do Asfalto e o Índice de Condição Atual dos Pavimentos baseado na metodologia M-MACBETH. Verificou-se que os resultados foram semelhantes entre si, na comparação dos resultados obtidos, e assim, as atividades das estratégias de intervenção, eram basicamente os mesmos. Portanto, o Índice de Condição dos Pavimentos do Instituto do Asfalto e o Índice de Condição Atual dos Pavimentos mostraram-se válidos e práticos para a avaliação da condição superficial de pavimentos urbanos flexíveis.

A excelência em gerenciamento de projetos exige uma boa estrutura de comunicação entre os envolvidos. Buscar a evolução é uma constante no mercado, e um caminho para isso é ter uma boa interface de acompanhamento com as partes interessadas para atuar o quanto antes em desvios, como também identificar e agir preventivamente enquanto estes são apenas vulnerabilidades e não impactam nos resultados esperados. O presente artigo, elaborado com base em uma investigação exploratória, com análise documental, propõe a melhoria do documento de acompanhamento de projeto intitulado Relatório Gerencial. Espera-se que as intervenções propostas passem a atender efetivamente todas as partes interessadas na carteira de projetos, possibilitando uma melhor integração dos dados e uma visão geral dos status e acompanhamento dos projetos em uma gerência de implantação de investimentos que atua em áreas diversas, distribuídas em 2 estados (MG e ES), para as várias naturezas de demandas que surgem para as equipes (civil, eletromecânica, geotecnia, SPCI, dentre outras). Essa gerência é atuante em uma empresa do setor de mineração. Como resultado, tem-se um novo modelo proposto de relatório gerencial, bem como as evoluções nas análises de dados que se tornaram possíveis após essa aplicação.

O projeto de um controlador de temperatura para processos de polimerização em batelada apresenta alguns desafios devido à alta geração de calor e ao aumento da viscosidade do meio reacional típico dessas reações. Este trabalho apresenta o projeto e a implementação de dois tipos de controladores de temperatura para um reator batelada que utiliza água como fluido refrigerante. Uma torre de resfriamento e uma caldeira são usadas para resfriar e/ou aquecer o fluido de resfriamento, respectivamente. Para verificar a robustez do controle, a vazão do fluido refrigerante foi alterada de uma reação para a outra. A mudança entre os modos de operação (isotérmico e isoperibólico) e alimentação de reagentes durante a reação também foram analisados e considerados como perturbações no sistema. Um modelo para o processo a partir de dados reais foi estimado e a função de transferência dos controladores foi definida. No caso da estrutura PID (Proporcional, Integral e Derivativo) a ação derivativa foi desconsiderada por exigir um forte desempenho das válvulas automáticas reduzindo sua vida útil. A estrutura do tipo IMC (Internal Model Control) garantiu a estabilidade do sistema mesmo durante a existência de perturbações.
METODOLOGIA DE PLANEJAMENTO MULTIESTÁGIOS DA EXPANSÃO DE SISTEMAS DE DISTRIBUIÇÃO DE ENERGIA ELÉTRICA USANDO O ALGORITMO DRAGONFLY

Published: February 2025

O sistema de energia elétrica está em constante expansão para atender à crescente demanda por energia elétrica dos consumidores. Neste contexto, reforços nas redes de distribuição podem ser necessários, tais como a substituição de condutores que excederam sua capacidade dentro do horizonte de planejamento considerado, ou até mesmo a alteração na configuração dos alimentadores, por meio da alteração do status de cada chave presente na rede, dentre outras possiblidades. Desta forma, este artigo propõe uma nova metodologia de planejamento da expansão de sistemas de distribuição de energia elétrica, formulado como um problema de otimização não-linear, e solucionado por meio do algoritmo heurístico Dragonfly (libélula), integrando Python (coleta de dados, manipulação das redes de distribuição de energia elétrica e apresentação dos resultados) e OpenDSS® (cálculo de fluxo de potência). O algoritmo Dragonfly foi responsável pela reconfiguração do alimentador, visando a minimização dos custos de expansão e de perdas técnicas. A metodologia proposta foi aplicada no alimentador de testes IEEE 123 barras adaptado, que possui diversas chaves, reguladores de tensão e transformadores. A aplicação da metodologia proposta permitiu uma redução de mais de 22% nos custos de expansão, utilizando 30 libélulas nas simulações, mostrando a efetividade do algoritmo proposto quando aplicado em sistemas de distribuição de energia elétrica.

O processo de degradação das estruturas de concreto armado é um fator importante e que gera preocupação na indústria da construção civil. Um dos agentes agressivos mais preocupantes é o dióxido de carbono, causador do fenômeno conhecido como carbonatação. A carbonatação é um dos fatores associados aos problemas de degradação precoce, pois é através dela que ocorre a redução do pH do concreto retirando a proteção alcalina que o mesmo exerce sobre as armaduras, ficando sujeitas à corrosão. Nos últimos anos houve um crescimento considerável de anomalias nas edificações, relacionadas a problemas de corrosão do aço, advindos do processo de carbonatação. Apesar de ser um fenômeno presente e responsável pela redução da vida útil e da durabilidade das estruturas a carbonatação ainda não é compreendida de maneira abrangente, por se tratar de um assunto complexo, afetado por muitos fatores. Com base nisso, realiza-se neste artigo uma revisão da literatura para aprofundar o conhecimento sobre a carbonatação e possibilitar a sua compreensão. A partir da pesquisa desenvolvida busca-se explicar as variáveis que influenciam esse fenômeno, além de apresentar e discutir modelos matemáticos empíricos utilizados para determinar a frente de carbonatação em elementos de concreto.

Published: February 2025

O presente artigo investiga aspectos fenomenológicos relacionados à formação ou evolução das configurações das estruturas de fluxos dos sistemas naturais, com bases nos conceitos e fundamentos da Teoria Constructal. Em outras palavras, o objetivo principal deste estudo é investigar se há diferenças entre estruturas que são construídas e evoluem considerando o regime transiente no modelo físico-matemático e estruturas que evoluem considerando somente o regime permanente. Para demonstrar essas diferenças, neste trabalho foi desenvolvido um algoritmo que implementa uma heurística de tomada de decisão que se baseia na Teoria Constructal para criar caminhos condutivos em ambos os regimes, permanent e e transiente. Os resultados obtidos mostraram que a consideração do regime transiente no modelo físico-matemático é relevante, pois o passo de tempo de construção influencia diretamente a eficiência térmica dos caminhos condutivos e tem um papel significativo na formação das suas estruturas de fluxo.

O presente estudo traz uma proposta de fechadura inteligente para portas que possa dispensar uma pessoa de ter que carregar e gerenciar chaves tradicionais. Tal proposta se baseia em um dispositivo IoT que exija um mínimo de adaptações para sua instalação e o mínimo de interações humano/computador para proceder com o bloqueio e desbloqueio da fechadura. Para tal, a referida fechadura inteligente foi desenvolvida usando uma placa ESP32, se comunicando com dispositivos chave por meio de Bluetooth Low Energy, com auxílio de uma fechadura por solenóide ou por meio de um servo e peças impressas em 3D para, assim,  proceder com o trancamento e abertura de fechaduras tradicionais já presentes na maioria das casas.

Authors: Dantas de Almeida Samuel , Itamar Schafer de Souza Sandi
Published: February 2025

A utilização de aletas em trocadores de calor é empregada visando o aumento da eficiência no processo de transferência de calor. Este trabalho estuda o espaçamento ótimo na transferência convectiva em aletas dispostas em um tubo, utilizando duas geometrias clássicas, as aletas circulares e as aletas quadradas. Comparou-se os resultados obtidos com o emprego de correlações empíricas, propostas na literatura, com os resultados obtidos com a simulação numérica. A ferramenta de trabalho na simulação foi o software comercial ANSYS CFX 2023R1©. Nas simulações numéricas as aletas quadradas e circulares foram analisadas, modificando o espaçamento e as dimensões das aletas.  Foram consideradas três tamanhos para as duas geometrias de aletas, e sete espaçamentos entre elas. Neste trabalho apresenta-se os valores das taxas de transferência de calor em função do espaçamento, da relação entre os diâmetros da aleta e tubo base, e da relação altura da aleta e do diâmetro do tubo. Mostra-se também: o número Nusselt, o comportamento do coeficiente convectivo, os campos de temperatura e velocidade para os casos simulados em convecção natural. Os resultados apontam que o espaçamento ótimo é da ordem de 6 mm e que as divergências entre o estudo numérico e teórico ficaram na faixa de 11%.
