Objetivo: Analisar a especialidade ortognática em paralelo com a cirurgia bucomaxilofacial, redigindo com base na literatura acerca de orientações ao paciente, protocolos de tratamento e comportamentos profissionais. Revisão bibliográfica: A ortodontia é um ramo da odontologia que trata a correção de discrepâncias ósseas, reestabelecendo a harmonia dento-facial. Necessita de uma maior ampliação de abordagem teórica, visto que é essencial o conhecimento de ambas as áreas. Pois, o cirurgião bucomaxilofacial e ortodontista compartilham dos mesmos princípios mecânicos da ortodontia, além de passos do tratamento e diversos cuidados pertinentes ao paciente. Afim de acarretar o sucesso clínico e uma maior relação entre profissional e paciente. Considerações finais: A partir desse estudo, foi possível relatar que a maioria dos problemas pós-cirúrgicos são a mudança na aparência do paciente e quadros de parestesia. Por conseguinte, é necessário que o cirurgião e ortodontista discorram de maneira detalhada sobre casos orto-cirúrgicos, evitando processos civis envolvendo a parte profissional, insatisfação do paciente, falta de informação e alterações faciais sem informações prévias.

Authors: Жукова Л.Н.
Published: March 2023

Вопросы междисциплинарного изучения арктических регионов Восточной Сибири и населяющих их малочисленных народов актуальны сегодня. В статье в диахронном и синхронном диапазонах анализируется годовой хозяйственный цикл локальной группы аборигенного юкагирского охотничье-рыболовного населения верхнего течения реки Колымы. В задачи исследования входит определение внешних и внутренних причин, обусловивших функционирование на периферии современного урбанизированного общества древней полукочевой культуры пеших номадов-собаководов. Цель работы заключается в выработке общих подходов к вопросам сохранения в исторической перспективе этно-экологического раритета международного значения. К сравнительным сопоставлениям привлекаются также данные фольклора и народных языческих воззрений лесных юкагиров (одулов). В арктической зоне Восточной Сибири родовая община «Тэки Одулок» занимается исключительно охотпромыслом и рыбной ловлей, диктат годового хозяйственного цикла отсекает все не соответствующие этому алгоритму виды хозяйственной деятельности. На основании изложенного при составлении Программы на долгосрочную перспективу предлагается провести комплексное исследование хозяйственно-экономической и культурологической ситуации в общине для формулирования реальных прогностических планов; считать одульскую культуру брендом Верхнеколымского улуса и Республики Саха (Якутия); обратиться в ЮНЕСКО с предложением о включении одульской культуры в соответствующий перечень.

The issues of interdisciplinary study of the Arctic regions of Eastern Siberia and the small-numbered peoples inhabiting them are relevant today. The article analyzes the annual economic cycle of the local group of the aboriginal Yukaghir hunting and fishing population in the upper reaches of the Kolyma River in the diachronic and synchronous ranges. The aim of the study is to determine external and internal reasons for the functioning of the ancient semi-nomadic culture of nomadic dog breeders on the periphery of the modern urbanized society. The aim of the study is to develop common approaches to the issues of preserving ethno-ecological rarity of international importance in the historical perspective. Data from folklore and folk pagan beliefs of the forest Yukaghirs (Oduls) are also involved in comparative comparisons. In the Arctic zone of Eastern Siberia, the «Teki Odulok» tribal community is engaged exclusively in hunting and fishing, the dictate of the annual economic cycle cuts off all economic activities not corresponding to this algorithm. Based on the above, when drawing up the long-term Programme, it is proposed to conduct a comprehensive study of the economic and cultural situation in the community in order to formulate realistic prognostic plans; to consider the Odul culture as a brand of Verkhnekolymsky ulus and the Republic of Sakha (Yakutia); apply to UNESCO with a proposal to include the Odul culture in the relevant list.

Nowadays the unmanned aerial vehicles (UAVs) become popular and are increas- ingly used in a wide range of applications. The UAVs are used as flying-based station to enable communication services to a ground station and are referred to as UAVs-assisted communication. Also, UAVs are used for a multitude of applications from cargo delivery to surveillance referred to as cellular-connected UAVs. This paper presents the methodology for 3D path planning for building health monitoring. The result of this study gives an optimal path for UAV which should be taken during the supervision of the building to detect the cracks on the surface of the building. The methodology combines the application of Dijkstra’s, Floyd – Warshall’s algorithms, travelling salesman problem (TSP), and hybrid particle swarm optimization algorithm (HPSO) for finding an optimized path in UAV moving around building for surveillance in the structural health monitoring.

Беспилотные летательные аппараты (БПЛА) становятся все более популярными и все чаще применяются в широком спектре приложений: от доставки грузов до наблюдения. Они также используются в качестве базовой станции для предоставления услуг связи с наземной станцией, и есть упоминания коммуникации на основе БПЛА. В статье представлена методология трехмерного планирования пути для мониторинга состояния здания. Результат этого исследования дает оптимальный путь для БПЛА, который следует использовать при осмотре здания для обнаружения трещин на его поверхности. Методика сочетает в себе применение алгоритмов Дейкстры, Флойда – Уоршалла, задачи коммивояжера и алгоритма оптимизации гибридного роя частиц для поиска оптимального пути движения БПЛА вокруг здания для наблюдения при мониторинге состояния конструкции.

Published: March 2023

Qualitative study problems of trajectories behaviour for singular Boolean networks functioning on a finite time interval are solved using the method of Boolean constraints. In the form of Boolean constraints, models are built for local dynamical properties, the periodicity property of trajectories, and the property of the reachability of the tar- get state set from the initial state set. Depending on the property, the verification of Boolean models is reduced to the Boolean satisfiability problem or the problem of verifying the truth of a quantified Boolean formula. Several examples demonstrate the technology of qualitative analysis of dynamic properties in a microservice het- erogeneous computing environment. The applied software modules for constructing a Boolean model of the dynamical property of singular Boolean networks and verifying the feasibility of the model are implemented in the form of computational microser- vices. The use of this approach provides independence, reproducibility, autonomy, and scalability of modules. The developed microservices are integrated into the applied microservices package. This package is intended for the qualitative study of binary dynamic systems. The rights to launch microservices are delegated to the managing agents of this package installed in the nodes of the distributed environment. The de- veloped automation tools allow a specialist in automaton dynamics to formulate the problem statement on a computational model of the subject area in meaningful terms.

Published: March 2023

We report here a novel series of halide alloyed Ge-containing 2D perovskites including decylammonium as organic spacer, namely DA2Ge(Br1-xIx)4. This system forms a continuous solid solution on the halide site with a modulation of the band gap from 2.74 to 2.17 eV with a rapid decrease up to x=0.5 followed by a plateau. Iodide-rich compositions show enhanced broad RT photoluminescence (PL) which narrows at low temperature with maximum quantum yields for mixed compositions. The replacement of Ge with Pb and Sn in DA2GeBr4 and DA2GeI4 provides a tuning of the band gap in the whole visible spectrum with a marked blue-shift when lead is present and, opposite, a red-shift for Sn replacement. The RT PL progressively broadens moving from Pb to Sn and to Ge covering an emission range from 400 to 800 nm. Finally, the air stability of lead-free 2D perovskites of this work has been determined indicating its improvement by increasing the hardness of the halide.
Single-Sequence Identification of Modified Peptides: A One-Pot Method Using Homologous Biotinyl Azides

Published: March 2023

Identifying probe-modified peptides in chemical proteomics experiments is challenging due to the production of only one modified peptide per probe reaction at a specific site on a protein and the possibility of inconclusive proteomic identification. To address these issues, we propose a principle of Single-Sequence Identification (SSI) and a method for identifying probe-modified peptides in chemical proteomics experiments. The new approach creates multiple versions of the modified peptide in the proteomic identification space to increase identification probability and confidence. The SSI method, tagging-triplication, is implemented using a one-pot triplex tagging approach, attaching three homologous biotinyl azides with different PEG linker lengths to clickable proteins. The identification of modified peptides carrying two forms of tags was assigned as confident, with tag diagnostic ions and elution time dependent on the linker length further enhancing confidence. Variability in CuAAC-tagged proteins was also identified, and a split-and-pool strategy was recommended to minimize the variability. The tagging-triplication method can be easily integrated into existing chemical proteomics workflows to identify peptides modified by alkynyl covalent probes confidently. Our findings demonstrate the potential of the SSI principle to significantly enhance modified peptide identification for proteomes with post-translational and chemical modifications. Data are available through ProteomeXchange: identifier PXD037770.
History-Agnostic Battery Degradation Inference

Published: March 2023

Lithium-ion batteries (LIBs) have attracted widespread attention as an efficient energy storage device on electric vehicles (EV) to achieve emission-free mobility. However, the performance of LIBs deteriorates with time and usage, and the state of health of used batteries are difficult to quantify and to date are poorly understood. Having accurate estimations of a battery's remaining life across different life stages would benefit maintenance, safety, and serve as a means of qualifying used batteries for second-life applications. Since the full history of a battery may not always be available in downstream applications, in this study, we demonstrate a deep learning framework that enables dynamic degradation trajectory prediction, while requiring only the most recent battery usage information. Specifically, our model takes a rolling window of current and voltage time-series inputs, and predicts the near-term and long-term capacity fade via a recurrent neural network. We exhaustively benchmark our model against a naive extrapolating model by evaluating the error on reconstructing the discharge capacity profile under different settings. We show that our model's performance in accurately inferring the battery's degradation profile is "agnostic" with respect to cell cycling history and its current state of health.

Metastable solid electrolytes exhibit superior conductivity compared to stable ones, making them a subject of considerable interest. However, solid-state synthesis of the metastable phase is affected by multiple thermodynamic and kinetic parameters, leading to ambiguity in the categorization of stability and metastability. This study categorizes remnant and intermediate metastability based on thermodynamic principles. The intermediate metastable phase, which is less stable than the temperature-independent stable phase, typically transforms into the stable phase(s) at high temperatures. In contrast, the remnant metastable phase, such as the high-temperature stable phase obtained by fast cooling, becomes the most stable phase, and annealing of the remnant metastable phase causes the phase transition to the low-temperature stable phase. Investigating Li+ conducting chlorides, Li3MCl6 (M = Y and Ho), this study shows that heating starting materials to approximately 600 K produced low-temperature Li3MCl6 phase with one formula unit; high-temperature Li3MCl6 with three formula units were observed by further heating. Annealing of quenched Li3MCl6 at 573 K resulted in a phase transition from high-temperature to low-temperature, indicating that the high-temperature phase was remnant metastable at low temperatures. XRD patterns of low-temperature phases suggest the presence of stacking faults that stabilize low-temperature structures with high symmetry.
The WHO’s communication strategies on social media during the early stage of the 2021 COVID vaccination campaign
Authors: Poch-But Santana Lois , Moreno Ángeles , Gelado-Marcos Roberto
Published: March 2023

The crisis caused by COVID-19 forced public and private actors to deploy various strategies on social media to communicate effectively with their public. This research analyses the institutional communication of the World Health Organization’s Twitter account during the first quarter of 2021, with the aim of shedding light on their strategy and analyzing both its strengths and the areas with room for improvement in a crisis like the one studied. For this purpose, an ethnographic content analysis was run on the tweets published by the institutional account of the WHO and the responses issued by the public. A computer-assisted analysis was undertaken through two software programs (SPSS 27 and NVivo 11), and an online tool, Onodo – that helped us develop a sociogram with the different relationships between the actors involved in the crisis and risk communication of the WHO around the subject of vaccination. The main results show, on the one hand, that vaccination is not the focal point of the WHO’s discourse at a time when the public’s interest was centered on said thematic axis, and on the other, that the organization was not able to create an effective dialogic space. Considering these findings, a reflection is encouraged to optimize professional praxis in future risk and crisis communication strategies in digital environments, expanding the scope of this study towards other organizations and/or time frames.
Inteligencia artificial en el periodismo deportivo: estudio en Brasil y Portugal
Authors: Canavilhas João , Giacomelli Fábio
Published: March 2023

La inteligencia artificial ha llegado al periodismo en diferentes fases del proceso de producción de noticias, desde la identificación de tendencias informativas, al tratamiento de datos o a la producción automática de textos, entre otros. Su potencial se manifiesta, sobre todo, cuando existe una gran cantidad de datos, algo que pueden ofrecer secciones como las de deportes y economía. De las dos opciones, en este trabajo se ha elegido el periodismo deportivo y, así, buscamos conocer y entender cómo los periódicos, radios, televisiones y productos nativos digitales de Brasil y Portugal se han relacionado con la inteligencia artificial (IA). Para lograr los objetivos propuestos, enviamos una encuesta a los responsables de varios medios de comunicación de ambos países con preguntas que nos ayudaron a darnos cuenta de que los editores y responsables conocen la contribución que la IA puede ofrecer a sus redacciones. Entre otros resultados obtenidos, destacamos que el uso de IA en los medios brasileños está más presente que en Portugal, pero hay una convergencia en sus usos y en las dificultades para obtener un mayor desarrollo: la falta de recursos económicos y los bajos conocimientos sobre el potencial de la IA. Entre las razones destacables para usar dicha tecnología está el objetivo de hacer más eficiente el trabajo de los periodistas y de ahorrar tiempo en la producción. Se concluye que los decisores de medios deportivos portugueses y brasileños son conscientes del potencial de la IA, pero ahora mismo las dificultades económicas y profesionales son el principal adversario para su implementación en las redacciones.

Impact of force application point in two-mass oscillation system on its energy efficiency
Authors: Zedgenizov V. G. , Faizov S. Kh.
Published: March 2023

Introduction. The goal is to perform a comparative analysis of energy consumption during the operation of a resonant two–mass mechanical system, depending on the point of application of the driving force to the first or second mass. The object of research is an oscillatory system of a vibrating machine consisting of two masses interconnected by elastic and dissipative elements. In addition, the first mass is connected to a fixed base through elastic and dissipative elements.Materials and methods. The research uses the main provisions of theoretical mechanics, mathematical modeling and simulation experiment in the Matlab-Simulink environment.Results. According to the results of research on a mathematical model of a two-mass oscillatory system with a point of application of the driving force to the first mass, it was found that with a driving force of 10 kN and a frequency of 80 rad/s, the amplitude of the oscillations of the first mass is 0,6 mm, and the second is 1,8 mm, while the amplitude gain is 3,94. To achieve the specified driving force, a directional debalance exciter with a mass of 10 kg of debalances must have an eccentricity of 0,16 m, and the power required to drive the oscillation exciter is 21,2 kW. In the case of applying a driving force to the second mass, it is possible to achieve the same amplitude of oscillations of the first mass (0,6 mm) with a driving force of 5 kN, an eccentricity of 0,078 m and a drive power of 4,9 kW, while the amplitude gain is 8,44.Originality. Thus, due to the dynamic properties of the two-mass system, the option with the point of application of the driving force to the second mass is 4,3 times more energy efficient than the option of applying the driving force to the first mass.

Published: March 2023

Introduction. Reducing the operating costs of motor fuel for cars is possible through the use of cheaper and at the same time less environmentally harmful alternative energy sources. The main problem with the use of these energy sources, especially for 1 category cars, is the underdeveloped infrastructure of the network of filling stations for alternative fuels. The main alternative type of motor fuel in the Russian Federation is natural gas. The use of compressed natural gas as a vehicle fuel on 1 category cars significantly increases zero mileage due to the remoteness of filling stations, which reduces the efficiency of using natural gas. The purpose of the research is to develop a methodology for calculating the cost of refueling with various types of motor fuel for 1 category cars, taking into account the location of refueling points (gas stations / gas filling stations / filling stations).Materials and Methods. The research presents a methodology for calculating the cost of refueling with various types of motor fuel, developed on the basis of a multivariate analysis of the vehicle performance, a given 1 category cars route, the driver’s work on the route, and the existing infrastructure of the filling station network. The scientific novelty is the establishment of the dependence of the cost of refueling with motor fuel on the type of fuel used, the existing infrastructure of the network of filling stations, the average daily mileage and on the technical and economic indicators of 1 category cars.Results. The developed methodology was tested at the enterprises that 1 category cars cargoes in the territory of Omsk. It has been established that for 1 category cars, when carrying out the process of transporting goods in Omsk, the cost of refueling with motor fuel will be from 1.77 to 15.62% of the average cost movement by the route.Discussion and conclusions. The methodology allows to determine the impact of the fuel used on the 1 category cars operating costs, to select an effective motor fuel, as well as to account for the cost of refueling with motor fuel and more accurately determine the cost of transporting goods.
¿Pueden las provisiones dinámicas mejorar la solvencia de los bancos?: Un estudio del Sistema Bancario Peruano
Authors: Condori Apaza José Edgar
Published: March 2023

The present study analyzed the effects that the implementation of the procyclical rule has had on the solvency of Peruvian banks. In a context where the crisis of 2008 reaffirmed the role of the financial system, mainly the banking system, whose problems had a negative impact on economic activity. In the Peruvian case, the pro-cyclical rule was implemented, which obliges banks to accumulate provisions in expansive stages of the economic cycle, so that they can then be used in stages of tension or reversal of the cycle. These additional provisions reduce the funds that could be destined in loans to the economy; however, it increases the funds available to deal with losses. Applying the voltage test methodology specified in Čihák (2007), for the Peruvian banking system before a first shock of adequacy of the stock level of provisions, it was found that the largest banks have maintained an adequate level of provisions. While in the case of a second shock, the increase in loans in the doubtful category, as a result of 23% of normal loans and potential problems downgrade, in this scenario the capital ratio is reduced to levels below 10%, the additional provisions only helped to reduce this impact on average to 0.05%.
A Framework of Rhetorical Moves Designed to Scaffold the Research Proposal Development Process
Authors: D Reddy Colin
Published: March 2023

Aim/Purpose: To provide a research proposal writing framework to help doctoral students argue and motivate their efforts at furthering the existing knowledge available to understand some phenomenon or theory.

Background: I discuss how the cognitive process theory of writing and the science writing heuristic can lead to a set of rhetorical moves and question prompts that students can use to develop the content of their research proposals.

Methodology: I searched the literature on research proposal writing and, more broadly, academic writing to locate teaching and learning concepts associated with my recent question prompt approach used to guide my doctoral students. I used search words such as “writing” and “question prompts.” My review led me to the cognitive process theory of writing and heuristic scaffolding. I searched further using keywords such as “rhetorical move” and “heuristic prompts.” I performed several iterations of literature searches and reviews.

Contribution: Instead of guiding a linearly developed research proposal that begins with an Introduction and proceeds to a Literature Review and then a Research Design and Methods section, the framework reveals a research proposal’s underlying logical flow and content by describing five rhetorical moves: establishing a topic question from an interesting phenomenon, establishing research opportunities, selecting a research question, providing a tentative solution, and establishing a plan to investigate the solution. Thus, the framework contributes to scholarship about how educators can facilitate independent reflection and broader problem-solving at the doctoral research proposal development stage. Particularly for the social sciences, it reveals the promise of the cognitive process theory of writing, dual problem space model of reflection, and heuristic scaffolding as valuable theoretical perspectives for the supervision of the planning phase of doctoral research.

Recommendations for Practitioners: Teachers and advisors may use the framework’s rhetorical moves and question prompts as cognitive scaffolds to help students navigate an ill-structured problem typical of doctoral research projects in the social sciences. The question type of scaffolding gives the research student more responsibility; rather than the thesis supervisor or advisor articulating a model or nominating the technique, they require the student to self-regulate and develop it independently. This helps deal with the oft-experienced circumstance in which the supervisor does not have time to interact directly and regularly with the student.

Background: The ABO blood antigens may influence the levels of vWF: Ag and put individuals at risk of coagulopathies. This study assessed the plasma vWF: Ag and its relation with ABO blood antigens among healthy adults in northern Ghana. Methods: This cross-sectional study recruited 84 blood donors, aged 18–50 years, at Tamale Teaching Hospital. Blood groups were determined using the standard tube method, and a complete blood count was measured with an automated haematology analyzer. Sandwich ELISA was used to assess plasma vWF: Ag levels. The data obtained were analyzed using SPSS version 22. Results: The frequencies of O, A, B, and AB blood groups were 34 (40.5%), 25 (29.8%), 20 (23.8%), and 5 (6.0%), respectively. vWF: Ag levels were higher among the non-O than group O individuals (p = 0.008). Plasma vWF: Ag levels were lower in group O compared to AB (p = 0.015) and A (p = 0.013) individuals. Males had higher vWF: Ag levels than females (p = 0.002). A moderately positive correlation was observed between age and vWF levels (r = 0.497, p<0.001). Blood group O participants had lower absolute neutrophil counts (p = 0.039), but higher RDW-SD (p = 0.045). Conclusion: The predominant blood group was O, followed by other groups in the order: O>A>B>AB. Plasma vWF: Ag levels were higher in non-group O compared with group O individuals. Males had higher vWF: Ag levels, and a positive correlation between age and vWF: Ag was observed. Again, blood group O participants had lower neutrophil counts, but higher RDW-SD. The relationship between ABO blood phenotypes and plasma vWF: Ag should be considered in clinical practice. The establishment of separate reference intervals of vWF: Ag for the various phenotypes of ABO is recommended. Also, the study recommends further multicenter studies to assess the link between ABO phenotypes and all the endothelial cell parameters. Doi: 10.28991/SciMedJ-2022-04-02-02 Full Text: PDF
Simple Physical Process Can Slow Down the Progression of Cancer
Authors: Garai Jozsef , Kertai Pal
Published: March 2023

If a liquid contains suspended solids and flows out of a perforated pipe, the suspended particles of the right size can accumulate and eventually clog the openings. It is suggested that this physical process could be employed to effectively block the openings of the intercellular gaps in angiogenic capillaries supplying cancer tissues. Clogging the big openings supplying cancer tissues would reduce the nutrition supply, resulting in deprivation. This process predictively could slow down the tumor progression. If the proposed physical process is effective, then societies that drink water containing colloidal-size particles should have fewer occurrences of cancer. Epidemiological data is consistent with this prediction and shows an inverse correlation between the total dissolved solid concentrations in drinking water and the incidence of cancer. The effectiveness of the proposed physical process was tested in a pilot project on six rats. Four of them had suspended kaolinite minerals in the drinking water, and two of them got regular tap water. All the treated rats developed smaller tumors than the untreated control group of two. The average weight of the developed tumors was 42 percent less in the treated group. Doi: 10.28991/SciMedJ-2022-0401-4 Full Text: PDF

Background: Venous thromboembolism (VTE) is a common and preventable disease among non-surgical hospitalized patients. Its incidence is high and alarming. Acute medical patients have VTE risk during and after hospitalization. The Padua prediction score is a risk model created to identify high VTE risk patients among non-surgical hospitalized patients. Methods: We performed a cross-sectional survey of 107 patients admitted to Internal Medicine wards who were assessed as acutely ill patients at Emergency Department, in a period of 4 weeks. The demographic and clinical data were collected using a designed questionnaire. VTE risk was defined as having a Padua Prediction score of ≥4 points. A statistical analysis was done to determine prevalence. The patients at high VTE risk received thromboprophylaxis. Results: One hundred and seven eligible patients were included. 84% were found to be at high risk for VTE. Among physiologically unstable patients, 60% of the patients were classified in red color during the time of triage; this means they were severely sick and needed resuscitation. Among the leading diagnosis, severe pneumonia was predominant (29%). Severe pneumonia and uncontrolled DM showed a significant association with high VTE risk. 11.1% of high VTE risk patients were taking anticoagulant thromboprophylaxis prior to the recruitment. Conclusion:This study demonstrated a high prevalence of VTE risk among acute ill medical patients and underuse of anticoagulants for thromboprophylaxis in potential patients at Kigali University Teaching Hospital, CHUK. The Padua prediction score should be implemented for early detection of patients at-risk of VTE in severely ill patients and to start anticoagulant thromboprophylaxis on time for reducing mortality and morbidity. Doi: 10.28991/SciMedJ-2022-0401-5 Full Text: PDF

Se reflexiona en torno a esa configuración a la luz de novedosas formas de entender el impacto que tiene el futuro sobre el presente y el pasado. Asimismo, aporta elementos para profundizar la comprensión de los alcances del imaginario/dispositivo sobre nuestras vidas, y la coexistencia de diversos imaginarios de futuro que dan forma no solo a nuestro porvenir, sino también a nuestro presente y la configuración del pasado. Su relevancia reside en la necesidad de pensar el futuro desde categorías socioculturales que nos permitan comprender su vinculación con el presente.
El cielo en la tierra. Dos horizontes para pensar un futuro desantrópico
Authors: Fernández Eva N. , Vázquez Estrada David Alejandro
Published: March 2023

El presente texto tiene como objetivo reflexionar sobre la premisa de un futuro diseñado, pensado e imaginado desde una aproximación des-antrópica que posibilite re-dirigir la vida planetaria. Está organizado en tres momentos: el primero describe la noción de tiempo y de futuro desde una visión antrópica, donde situamos las principales discusiones sobre modos de significar y comprender el instante y el devenir; el segundo aborda el giro desantrópico en las ciencias sociales, posición que ubica a lo humano en diálogo con lo no humano estableciendo relaciones de parentesco otras. En el tercer momento narramos dos experiencias desde la etnografía: la de Don Andrés, experimentado rezandero chichimeca (tierra) y la del Aeroceno del artista, arquitecto y activista Tomás Saraceno (aire), donde ambos sostienen discursos iluminadores y factibles para pensar los futuros en plural y, sobre todo, más allá de lo humano.
Futuros, especulaciones y diseños para otros horizontes posibles
Authors: Reina-Rozo Juan David
Published: March 2023

El articulo presenta una revisión, reflexión y replanteamiento de los estudios de futuro(s) en el contexto de un terracidio motivado principalmente por el capitaloceno. Lo anterior, a partir de una limitada concepción de los imaginarios de futuros presentes en nuestra(s) sociedad(es), caracterizados por una tendencia tecno-determinista, poniendo en cuestión el monofuturismo. Por tanto, se manifiesta el rol de la especulación, la imaginación, y los diseños críticos como marco referencial para reclamar de nuevo nuestro(s) futuro(s). En este camino, se describen seis ramificaciones de los etnofuturismos como una espacio cultural, comparado y contextual desde los movimientos culturales y artísticos. Abriendo la discusión ampliamente para considerar el diseño especulativo, la ficción científica y la ficcionalización de los sistemas de conocimiento alternos como espacio fértil para futuros pluriversales mucho más que humanos.
A Smart Movie Suitability Rating System Based on Subtitle
Authors: IŞIK Murat
Published: March 2023

With the enormous growth rate in the number of movies coming into our lives, it can be very challenging to decide whether a movie is suitable for a family or not. Almost every country has a Movie Rating System that determines movies’ suitability age. But these current movie rating systems require watching the full movie with a professional. In this paper, we developed a model which can determine the rating level of the movie by only using its subtitle without any professional interfere. To convert the text data to numbers, we use TF-IDF vectorizer, WIDF vectorizer and Glasgow Weighting Scheme. We utilized random forest, support vector machine, k-nearest neighbor and multinomial naive bayes to find the best combination that achieves the highest results. We achieved an accuracy of 85%. The result of our classification approach is promising and can be used by the movie rating committee for pre-evaluation.

Cautionary Note: In some chapters of this paper may contain some words that many will find offensive or inappropriateness; however, this cannot be avoided owing to the nature of the work

Bu çalışmada, ağaç ürünler üretiminde yaygın olarak kullanılan Sarıçam, kestane ve meşe odunu örneklere 150℃’de 5 saat, 170℃’de 4 saat, 190℃’de 3 saat, 210℃’de 2 saatlik sıcaklık ve sürelerle ThermoWood yöntemiyle ısıl işlem uygulanmıştır. Isıl işlemde sıcaklık artarken işlem sürenin azalmasının ahşap özelliklerindeki değişken etkileri araştırılmıştır. Bu maksatla üç ahşap türünden toplam 1440 adet örnek hazırlanmıştır. Isıl işlemden sonra örneklere 20℃ sıcaklık %65 nispi nem, 40℃ sıcaklık %35 nispi nem, 10℃ sıcaklık %50 nispi nem şartlarında klimatik işlem uygulanmış ve bu örneklerde ilgili standartlara göre; yoğunluk, eğilme direnci, elastiklik modülü, ısı iletkenlik katsayısı ve ısı geçirgenlik değeri değişimleri belirlenmiştir. Sonuç olarak, düşük sıcaklık ve uzun süreli ısıl işlem konseptlerinde ahşabın yapısal bozunuma bağlı fiziksel ve mekanik özelliklerinde kayıpları az iken, yüksek sıcaklık ve kısa süreli ısıl işlem konseptlerinde bu kayıpların daha fazla arttığı, bu nedenle 170℃/4s ve 190℃/3s ısıl işlem konseptlerinin daha uygun olduğu, ahşabın öz yükünün ve ısıl iletkenlik katsayısının azaldığı, yalıtkanlığının ve mekanik direnç değerlerinin artış kaydettiği, ahşap kullanımı için (denge rutubeti bakımından) uygun olan iklim şartının ise 40C/%35 olduğu tespit edilmiştir.

Biomimetik yaklaşım, tasarım araştırmaları alanında yeni olanaklar sunmakta olup süperhidrofobik yüzey tasarımı bu alanlardan bir tanesidir. Bir yüzeyin geometrik ve kimyasal özellikleri süperhidrofobisite için belirleyici olan asli faktörlerdir. Bu çerçevede biomimetik yaklaşım, doğadaki süperhidrofobik bir yüzeyin geometrik özelliklerinin tasarlanan süperhidrofobik bir yüzeye aktarılmasında kullanılabilir. Tasarlanan modelin, belirlenen geometrik özelliklere sahip olacak şekilde imal edilebilmesi için uygun bir imalat yönteminin seçilmesi önemlidir. Yüzeyin gerekli kimyasal özelliklere sahip olabilmesi içinse malzeme seçimi önemli olmaktadır. Bu çalışmada, biomimetik yaklaşım kullanılarak süperhidrofobik yüzey imal edilmesi konusu ele alınmıştır. Bu çerçevede, süperhidrofobisite kavramının yıllar içinde gelişen teorik altyapısı incelenmiş olup üç boyutlu yazıcı ile model imal edilmesi, karbon nanotüp esaslı nanokompozit malzeme geliştirilmesi ve geliştirilen nanokompozit malzeme kullanılarak elektrospinning ile yüzey kaplanması işlemlerinden oluşan bir yöntemler bütününün süperhidrofobik yüzey imal edilmesinde uygulanabilirliği değerlendirilmiştir.
KARRİKİN: DUMANDAN GELEN YAŞAM

Karrikinler (KAR) orman yangınları sırasında yanan bitkisel materyalin dumanında bulunan bir bitki büyüme düzenleyicisi gibi görev alan benzersiz bütenolitlerdir. Dumanın içeriğinde yer alan KAR’lar, bitki topluluklarının bolluğunu hızlandırarak tohum çimlenmesini, fide oluşumunu ve ekolojik çeşitliliği teşvik ederler. KAR’ler ayrıca oksidatif stres, kuraklık, düşük ışık yoğunluğu (gölge stresi) ve tuzluluk gibi farklı yetersiz koşullara karşı toleransa aracılık ederler. Sinyal yolu strigolaktonlar ile yakından ilişkilidir, ancak strigolaktonlardan farklıdır. Strigolaktonlar ile yapısal akrabalık nedeniyle, KAR'lar bitkilerde abiyotik stres toleransına aracılık etmede potansiyel rollere sahiptir. Ek olarak KAR, absisik asit, giberellik asit, oksinler ve etilen gibi önemli fitohormonlarla doğrudan ya da dolaylı olarak etkileşime girerler. Bu makale ile karrikin ve duman suyuna dair pek çok güncel çalışmaya değinilmiştir.
