Authors: Andrade Abreu Marleny , Dávila de Sousa Soares Flaviana , Paula de Souza Rego Pinto Carvalho Diana
Published: November 2024

A educação brasileira, de modo geral, tem sido instituída numa prática bancária, centrada na transmissão de conteúdo. Apesar disso, práticas educativas pautadas em um processo de ensino-aprendizagem que se fundamenta na problematização, no diálogo, na valorização das experiências de vida cotidiana e da cultura dos alunos são desenvolvidas. Paulo Freire é considerado o principal autor que fundamenta práticas de ensino com essas características. Diante disso, foi realizada uma revisão integrativa da literatura que objetivou responder a seguinte questão: quais as contribuições de Paulo Freire para o ensino em saúde? A partir da busca nas bases de dados disponíveis na internet: Biblioteca Virtual Scientific Electronic Library Online, Biblioteca Virtual em Saúde e a base de dados da Literatura Latino-Americana e do Caribe em Ciências da Saúde. Verificou-se a presença de pressupostos freirianos em práticas educativas dirigidas tanto para a formação básica como para a formação dos profissionais em saúde de maneira consciente e emancipado, que faz repercutir em seu trabalho as características de uma educação libertadora e dialógica.
Unified Forecast System Prediction of the Madden-Julian Oscillation and East Pacific Teleconnections During Boreal Summer
Authors: Tsai Yu Cian , Maloney Eric Daniel , Kim Daehyun , Camargo Suzana J
Published: November 2024

This study evaluates the subseasonal to seasonal (S2S) prediction skill
of the Madden-Julian Oscillation (MJO) and its remote impacts on the
east Pacific (EP) tropical cyclogenesis in the Unified Forecast System
(UFS) during boreal summer (May–October). Utilizing four experimental
versions, Prototypes 5-8, the study finds that although the UFS
generally captures the MJO’s propagation characteristics near the
initialization time, it encounters difficulty in accurately predicting
the propagation speed and decay rate of the MJO beyond 15 days.
Specifically, the phase transition rate of the MJO in the UFS is slower
than observed, although this behavior is improved in Prototype 8. The
UFS overestimates anomalies in the intraseasonal east Pacific genesis
potential index anomalies associated with MJO phases. Analysis of the
vertically integrated moist static energy (MSE) budget reveals that all
four UFS prototypes underestimate the damping effect of vertical MSE
advection and the amplifying effect of longwave radiative heating,
indicating weaknesses in tropical convective parameterization and cloud
radiative feedbacks, although these biases are somewhat improved in
Prototype 8. These deficiencies result in less efficient vertical MSE
export, weaker damping of MJO convection, slow MJO propagation, and
delayed MJO remote impacts on the EP. Thus, improving the UFS’ ability
to simulate MJO propagation and maintenance processes is crucial for
better predicting the MJO’s remote effects on EP TC genesis and
enhancing S2S forecast capability for such extreme events.
Estimates of the Global Clear-Sky Radiative Feedback Strength from Reanalysis Data
Authors: Gloeckner Helene Marie , Kluft Lukas , Schmidt Hauke , Stevens Bjorn
Published: November 2024

We use atmospheric profiles from ERA5, JRA55 and MERRA2 between 1993 and
2023 to estimate Earth’s global clear-sky longwave feedback strength on
the seasonal and interannual timescale. Differences in the relationship
of relative humidity with skin temperature prior to 2008 lead to
interannual feedback strengths between 1.34 W m−2 K−1 (JRA55) and 1.89 W
m−2 K−1 (MERRA2). Restricting the analysis to the last 16 years yields
more consistent interannual estimates of 2.05 W m−2 K−1 on average,
which is larger than the overall seasonal estimate of 1.91 W m−2 K−1.
The mid-tropospheric drying causing this difference suggest a
substantial influence of ENSO variability on the interannual timescale.
This indicates a long-term feedback strength smaller than 2.0 W m−2 K−1,
which is already at the lower end of previous estimates; emphasizing the
importance of accurate long-term RH measurements to reliably project
Earth’s clear-sky feedback strength

Published: November 2024

Effective waste collection is essential in homes and offices to maintain a healthy society, particularly for the elderly and individuals with disabilities. Smart technologies offer an innovative approach to addressing real-world challenges and fostering sustainable development. This system uses a microcontroller, ultrasonic sensors (HC-SR04) to detect the distance or movement of objects, an Arduino Uno as software frame work, a servo motor to open the lid, and a battery for continous power. Automatic activation is triggered by body gestures, making the system both user-friendly and efficient in waste disposal. The ultrasonic sensor detects a user's presence and sends signal to the Arduino Uno board which in turn activates the servo motor to open the dustbin lid. This operation minimizes the risk of contamination, as waste can be disposed without direct contact with the bin. The dustbin is mounted on an autonomous system that moves towards the user and returns to its designated position using features like line-following, path-finding, and Bluetooth-based (HC-05) wireless control for intelligent navigation. Keywords: Ultrasonic sensor, Autonomous system, smart bin, AI, Navigation, Gesture, Body.

Published: November 2024

Google Translate performance evaluation in translating between English and three Nigerian languages: Yoruba, Igbo, and Hausa, highlighting its strengths and limitations using the Turing Test. The study assessed whether participants could distinguish Artificial Intelligence (AI) - generated translations from human translations which reveals that Google Translate handles basic communication in these languages but struggles with more complex linguistic features. The tool adequately translates straightforward sentences in Yoruba language, but falters with idiomatic expressions, proverbs, and tonal nuances, the same problem refects in Igbo language facing challenges with more complex sentences and dialectal variations, resulting in culturally irrelevant outputs. Hausa performed better due to the availability of a larger training dataset, delivering more accurate translations for common phrases, but still struggled with cultural and contextual nuances.The findings suggest that Google Translate's limitations prevent it from passing a Turing Test with native speakers of Yoruba, Igbo, and Hausa. While understandable translations are produced for basic sentences, native speakers can easily detect inconsistencies, awkward phrasing, and a lack of cultural nuance. These issues underscore the significant gap between AI translation and human-like proficiency for African languages.

Short Communication: Governance type bias in global ranger survey: Implications for relevance and analogous future works
Authors: Parker Ben , Hoffmann Michael , Singh Rohit , McVey Drew , Ruiz Lucia
Published: November 2024

A growing body of literature explores rangers perceptions and experiences of implementing conservation activities. In particular, the Global Ranger Perception Survey, carried out by the WWF, is the largest global assessment of ranger perceptions and experiences of working conditions in protected and conserved areas, providing insights into various aspects of the profession of rangers. Nevertheless, when the ranger perception survey data was associated with site governance type, we found that the survey is dominated by protected and conserved areas governed by government agencies (81 per cent) while sites with Indigenous and community governance were poorly represented (10 per cent) despite the vast area under this form of governance globally. These biases in governance mean that the survey data will be less relevant to protected and conserved areas with less government involvement, such as privately protected areas and those governed by Indigenous peoples and local communities. Our study therefore indicates that future large-scale surveys of ranger perceptions and experiences would benefit from including a more diverse set of sites with regards to governance types. Further, there could be value in carrying out a new survey akin to the Global Ranger Perception Survey with a focus on protected and conserved areas governed by Indigenous peoples and local communities.

Published: November 2024

The article presents an analysis of the method of lifting large-span coatings using the pull-up method and introduces a new structural-technological solution for erecting coatings using mechanized technological equipment in the form of a lifting module. According to the solution, the load-bearing beams of the coating are moved in the space between paired columns of the frame, resting on the lifting modules. Guide profiles fixed to the inner surfaces of the columns serve as supports for the alternating support of the platforms of the lifting module, which pushes the coating beams in the inter-column space. The developed solution optimizes the lifting processes and reduces the duration of lifting works by minimizing the number of installations works to operations for fixing the beams of the coating at the design height and automating the processes of pushing the coating with lifting modules.

The results of an analytical review of a large number of publications on the problem of improving the efficiency of thermoelectric generators (TEG) over the past decade are presented. An analysis of historical data on the thermodynamic justification of the efficiency of thermoelectric generators is presented. The following areas are analyzed: the problem of increasing the figure of merit Z through the creation of new material science technologies and new materials, the creation of multi-segment thermoelectric elements for a wide temperature range (300 ÷ 1200 K), the efficiency of heat supply to the TEG and cooling. The methods for calculating the thermodynamic efficiency of TEG are presented. It is shown that the efficiency of TEG is limited to ½ of the Carnot value for ZT values of 1-3. Modern materials allow the production of TEG with ZT values less than 1. However, the application of TEG has promising prospects with the increase in the intensity of heat supply and cooling processes. The main directions and trends (physical, chemical, technological) in the creation and improvement of TEG are identified. Some practical solutions presented in the literature, as well as the authors' solution for improving the thermodynamic efficiency of boiler units using TEG, are shown.

Authors:   Department of Highways and Bridges, Lviv Polytechnic National University, Koval Maksym
Published: November 2024

The case of determining the serviceability of bridge beams with manufacturing defects is considered. Based on the results of visual inspection and non-destructive testing, it was found that the defects have a minor impact on the performance of the beams, and the characteristics of the building materials are high. The results of the calculations showed that the beams had almost twice the safety margin compared to the design requirements. The results of field tests of beams showed reliable anchoring of the working reinforcement, proper deformability and crack resistance of the beams. Usage of the acoustic emission method during field tests allowed to establish that the beams had no internal defects that could develop under load and reduce performance. Based on the results of the research, it was concluded that the beams manufactured with defects are suitable for use after the defects have been repaired.

The article reviews the features of the study of residual binder obtained from bituminous emulsions using the SUPERPAVE system. The need to add improving additives to bituminous emulsions, namely modifiers (polymeric and adhesive additives) and special additives of different effects (solvents, stabilizers, thickeners, defoamers) is characterized. It is determined that the effect of special additives with different effects on the properties of the residual binder of the emulsion is not fully investigated. It is shown that the method of obtaining residual binder from bitumen emulsions in the laboratory is especially important. Today, all methods of obtaining residual binder from an emulsion can be divided into high-temperature distillation methods and low-temperature evaporation. The literature review confirmed that the high-temperature and low-temperature performance characteristics of the residual binder of emulsions primarily depend on the amount and type of modifier and emulsifier used.

This article analyzes the difficulties in reproducing the actual circumstances of concrete compaction with rollers in the laboratory and mix design аfeatures of RCCP (Roller Compacted Concrete Pavement). While quick and straightforward, the Proctor compaction test may not adequately reflect the field compaction achieved with rollers. Gyratory compactors simulate the movement of the rollers, providing a more realistic situation with greater accuracy. However, they are expensive and require specialized knowledge. Due to the Vibratory hammer limited application and unrealistic vibration pattern compared to rollers, it is mostly used in laboratories for sample preparation rather than compaction. A vibrating table is effective for less rigid RCC mixture combinations and provides good compaction, although it does not perfectly simulate the action of a roller. The paper also underlines the need to create a link between density and moisture content to achieve maximum RCC performance.

Published: November 2024

The effect of natural and synthetic zeolite on the microstructure of cement matrix and mechanical properties of concretes was studied in the article. Results show that the addition of these pozzolanic materials results in the increase both compressive and flexural strength after 28 days of hardening. The concrete incorporating 10 mass.% of synthetic zeolite Na-P1 characterizes the highest compressive and flexural strength that reaches 53.5 and 7.8 MPa and exceeds the strength of reference concrete by 18 and 24%, respectively. This increase is the result of the improvement of the concrete on the microstructural level due to the formation of the additional amount of fibre-like crystals of hydrosilicates in the non-clinker part of the cement matrix providing its self-reinforcement.

Published: November 2024

This article presents a study of the use of composite materials in strengthening building structures. Materials consisting of two or more components or phases are called composite. Now modern composite materials open up new opportunities for design in all areas of production. The construction industry is no exception. Laminates, canvases, nets, rebars and ropes made of high-strength fibers of various origins are among the most widely used in construction at the moment. The main components of any composite are high-strength fibers that absorb the load, and a stabilizing matrix that serves to transfer forces to the fibers. The following types of high-strength fibers are used in composites: glass fibers, carbon fibers, organic fibers, silicon-carbon, aluminum-silicon fibers, and others. With the help of composite reinforcement, it is possible to effectively strengthen normal and inclined sections of reinforced concrete structures.

Published: November 2024

One of the main problems of hardening monolithic cement concrete, especially in the conditions of restoration and reconstruction of various objects, is the hardening of concrete in conditions of negative temperatures. Winter concreting technologies are divided into two main methods: the thermos method, in which the temperature of the environment in which the concrete hardens, must be above zero degrees Celsius, or the use of antifreeze additives. In the last case, it is advisable to introduce antifreeze chemical additives into the concrete composition, which lower the freezing temperature of water in concrete. However, previously conducted studies are known that show that even in the case of early freezing of concrete, its quality remains high. In this case, it is necessary that the beginning of setting of the cement paste occurs before the concrete can freeze. In addition, it has been suggested that concrete hardening at low temperatures can occur without using the thermos method. The article presents the results of the influence of hardening temperature on the setting time of cement paste. It is shown how hardening conditions affect on the strength and frost resistance of concrete.

Buildings often require inspection or reconstruction of reinforced concrete elements due to new regulations, technical equipment and changes in operating conditions. During reconstruction, there is a need for through openings to lay utilities and install modern engineering systems. Studies show that such openings generally reduce the strength of reinforced concrete elements. The impact of openings depends on their location, size and shape: openings in the support areas and compression zones have the most negative impact on strength, while openings in the middle of the span or neutral axis are less harmful. Round openings have a smaller effect on stresses than square openings. However, there is still insufficient research on the impact of such openings on structures in service, which requires additional research to formulate clear recommendations and ensure the reliability of buildings in the long term.
MARIA MARIA! Exploring Filipina Identity Through Mixed-Media Graphic Design
Authors: Cruz Maria Pilar , Mortensen Steagall Marcos
Published: November 2024

This practice-led project explores Filipina Identity through mixed media graphic design, asking how two halves of a Pre and Post-Colonial female identity may exist in visual and narrative harmony. Through a series of seven assemblages, the practitioner takes the bold landscapes and bright, colourful creatures of Pre-Colonial Philippine mythology into the intensely sacred space of devotional shrines. In doing so, the project reviews key areas of Western Storytelling; Filipino Cubism; and 20th Century Assemblage. By using Western devices to frame indigenous content, the practitioner hopes to create a timeless, familiar narrative with a native twist.

Using communication design to create a brand identity, which is designed to educate young female adults on gut health and encourage healthier eating. Be Picky is a healthy snack option that advocates for good gut health, by educating and encouraging consumers to make healthier food choices, all while healing their gut. In recent years, studies have shown there to be an evident decline in human gut health, due to the decrease in probiotic-rich foods present in our diets. This leads to poor life quality and a series of other health implications. However, this can be prevented with an increased intake of good bacterias and probiotics, commonly found in fermented foods such as pickles. Using digital illustration, linocut and branding exploration through communication design to create a pickle brand made to benefit your gut health, tailored to appeal to the younger female audience. This project heavily relates to my own experiences regarding gut health, and how a solution like this would greatly improve the quality of life for so many, by motivating others to improve and maintain a healthy gut.

From Third Place is a practice-led project that explores the concept of third place in relation to society of the inner city, specifically Auckland CBD, using the traditional cultural anthropological methods of fieldwork and observational drawing to explore third places in Auckland. This project addresses the concept of third place and its role within society and the individual, reflecting on how we connect within our environment. This project is heavily influenced by my previous degree in cultural anthropology and art history. The inquiry is explored through the publication in three chapters of observational illustrations which focuses on the main third places used in everyday life by residents of Auckland CBD; cafes, parks, and pubs. The resulting publication is a series of snapshots of life in the city. The aims of this project is to explore connection of individuals in the city and celebrate the third places that facilitate them.
A Deep Dive: Enhancing Swimmer’s Performance Through Journaling, Value-Based Performance, and Growth Mindset.
Authors: Elliott Blake , Mortensen Steagall Marcos
Published: November 2024

In ‘A Deep Dive’ I evaluate how journaling, editorial design, and tokens can be used to enhance swimmers’ performance. Becoming a high-performance swimmer requires a strong mindset to overcome challenging situations and perform at the highest level. As an aspiring high-performance swimmer, I have used personal experiences to develop a strategy to overcome these inherent challenges within the sport. Using an autoethnographic and reflective inquiry I incorporate methodologies’ such as drawing, prototyping, critical feedback, digital creation, and photography to bring this project to fruition. Drawing insights from contextual areas such as growth mindset, journaling, value-based performance, and the work of practitioner’s, Maritn Naumann, and Chris Harkin I have created three distinct artifacts: a mindset journal, a book, and five value tokens.
