Task-Based Learning (TBL) is a widely recognized and effective teaching method used by English Language Teaching (ELT) practitioners globally. Designing and developing tasks for a language classroom can be challenging due to the numerous factors that need to be reviewed, Factors such as learner input, goals, learner roles, teacher roles, task difficulty, task feasibility, and task sequencing are crucial. Once developed, these tasks can be adapted for various classrooms based on learners’ proficiency levels. This paper aims to make Computer Assisted Language Learning (CALL) more accessible and enjoyable by presenting and analyzing several tasks designed for language laboratories. Many tasks are based on YouTube videos. The paper examines selected YouTube videos downloaded to the master console, evaluating their potential for providing comprehensible language input in the classroom. It then discusses the effectiveness of these tasks, along with their advantages, disadvantages, and implications.
CRITIQUING MODERNITY: A STUDY ON THE POSTCOLONIAL ‘HOMECOMING’ IN R PARTHASARATHY’S ROUGH PASSAGE
Authors: Samad K Mr. Abdul , Kotta Dr. Basheer
Published: November 2024

R Parthasarathy’s verses have won critical acclaim for their distant yet passionate evocation of the modernist themes in Indian English poetry. Listed among the literary modernists of the post-independent era headed by Nissim Ezekiel, he blended the modernist alienation with postcolonial disillusionment and created a distinctive ‘Indian English idiom’ to express the deep concerns of the postcolonial societies. Drawing heavily from Indian regional cultural resources, his poetry follows the mimicking subjects from the colonies, their disenchantment with the coloniser and the journey home. This enables him to champion the cause of postcolonial cultural assertion without compromising the narrative conventions of literary modernism. Contextualising the poetic collection Rough Passage, the paper analyses the cultural implications of Parthasarathy’s poetry and argues that the culture he presented as Indian are largely high cultural forms and thus his poetry falls prey to the cultural debate in Britain in the early 20th century. Contrasting high and low cultural forms present in the collection, the paper exposes the role colonial cultural thought plays in the formulation of postcolonial discourses.

Authors: Abdalla Babiker Ahmed Adam
Published: November 2024

This study focused on writings errors of non-English major students. It aimed at finding non- English major students’ weakness areas in writing and to provide some solutions. Also, the study attempted to find the role of literature in improving writing skills of students. In addition, the study aimed at helping students to overcome their writing errors. Following the test method for data collection; 50 written documents by the sample were rationally and descriptively analyzed and discussed. The study findings revealed that the majority of the participants have errors in writing in English. These problems represented in grammatical errors, spelling errors, punctuation problems, capitalization errors and shortage of vocabulary. In addition, the findings showed that literature plays an important role in improving students’ writings skills. Based on the findings, some conclusions can be drawn: English language foundations need to incorporate literature in language classrooms of nonEnglish major students. In addition, English language learners have to adopt reading appropriate literary texts outside the classrooms as a strategy to practice the language and overcome their writings errors. Lastly, the study is limited to students of male section at Tabuk University. So, future researches are needed to cover the female section and teachers’ views.

Published: November 2024

Academics and businesses alike are presently fixated on the Sixth Generation (6G) network, which is seen as the telecom industry’s next major game-changer. The 6G architecture has not been finalized and is not yet being used in commercial settings. Research and development for 6G is still in its early stages. Several important features and technologies have surfaced as possible 6G system underpinnings, while development is still in its early phases. To facilitate the next generation of 3D modeling applications, this article suggests a new 6G cellular communication architecture. Aware of 6G’s revolutionary potential, we investigate its fundamental features to build a collaborative, real-time 3D modeling environment with unmatched capabilities. The goal of this project is to design the architecture for the next generation of communications systems. This will incorporate elements from two existing designs: the decoupled RAN design, which improves security and smooth data sorting, and the high-level design, which incorporates numerous protocols inside the antenna for stringent protection. Lastly, we delve into the possible sector-specific disruptions caused by this design and examine its wider implications for the future of 3D modeling. We hope that by introducing this new 6G architecture, we may inspire more study and development towards a day when 6G technology completely changes the game when it comes to 3D modeling.
CORE: Counteracting overwhelming requests effectively—A method for interest flooding attack mitigation in NDNoT
Authors: Bilgili Sedat , Ertit Gökçe , Demir Alper Kamil
Published: November 2024

The Named Data Network (NDN) is a promising architecture for the near future. NDN communicates by naming data, unlike IP-based Internet architecture. Architectural understandability, ease of use, security, content presentation, and simplicity of data exchange logic make this architecture preferable. The NDNoT approach, which recently combines IoT and NDN, enables Internet of Things applications using NDN naming conventions and basic data structure. However, increasing technological applications bring security vulnerabilities. In this study, we propose a new method called CORE that will secure the intended data transfer. The presented CORE mechanism was developed as a countermeasure against the Interest Flooding attack, one of the NDN security attacks. Tests were carried out in the Cooja simulation environment using three different topology scenarios. CORE’s performance metrics were evaluated based on success rate, average delay, and interest traffic. The results showed that when the CORE mechanism was active, there was an improvement in the success rate and average delay. In terms of interest traffic, at least a 70% success rate was achieved compared to scenarios in which the CORE mechanism was not operated.

Published: November 2024

BACKGROUND

Kidney transplantation is the most effective means to treat patients with renal failure, but its postoperative problems such as rejection reactions, immunosuppressant poisoning, chronic transplant kidney nephropathy, etc. still have not been effectively solved. This study searched for literature on traditional Chinese medicine (TCM) syndromes after kidney transplantation in China, conducted statistical analysis of the results, and sought to identify the underlying patterns.

AIM

To understand the TCM syndromes after renal transplantation and associated rules and provide a theoretical basis for further clinical research.

METHODS

The literature pertaining to TCM syndromes in renal transplantation, published in the China National Knowledge Infrastructure, Wanfang database, and WIP database from 1970 to 2021, was meticulously searched and comprehensively and statistically analyzed.

RESULTS

Following the established inclusion and exclusion criteria, 13 studies were selected for analysis. Post-renal transplantation, no significant discrepancy was noted among the groups based on the location of TCM viscera. However, when categorized according to TCM pathogenic factors, the groups with spleen and kidney yang deficiency, as well as liver and kidney yin deficiency, exhibited a statistically significant difference in the frequency.

CONCLUSION

Currently, the research on TCM syndromes pertaining to renal transplantation is in its nascent phase. It is imperative to conduct a multicentric, large-scale survey of TCM syndromes subsequent to renal transplantation in the ensuing years.

Published: November 2024

BACKGROUND

Hepatocellular carcinoma (HCC) is a leading cause of cancer-related deaths worldwide. Liver transplantation (LT) offers the most effective treatment. HCC recurrence is the strongest risk factor that decreases post-LT survival in patients transplanted for HCC. The rate of HCC recurrence is generally reported as 8%-20% in the literature. Many predictors of HCC have already been researched, however, to our knowledge there are no published studies on this topic using Australian data.

AIM

To determine the rate and identify predictors of HCC recurrence in a contemporary Western Australian LT cohort.

METHODS

We performed a retrospective cohort study of all liver transplants in patients with HCC at Sir Charles Gairdner Hospital between 2006 and 2021. Data was collected from various health record databases and included recipient demographics, serum biochemistry, radiology, operation notes, explant histopathology and details of recurrence. Overall survival of HCC patients post-LT, stratified for recurrence, was calculated by Kaplan Meier analysis. Univariate and multivariate Cox regression was used to determine predictors of HCC recurrence post-LT.

RESULTS

Between 1/1/2006 and 12/31/2021, 119 patients were transplanted with HCC. 8.4% of subjects developed recurrent HCC after LT with median follow-up time of 5.4 years. The median time to recurrence was 2.9 years ± 0.75 years. When comparing baseline characteristics, a greater proportion of subjects with recurrence had common characteristics on explant histopathology, including > 3 viable nodules (P = 0.001), vascular invasion (P = 0.003) and poorly differentiated HCC (P = 0.03). Unadjusted survival curves showed lower 1-year, 3-year, 5-year and 10-year survival rates in subjects with HCC recurrence compared to those without HCC recurrence (90% vs 92%, 70% vs 88%, 42% vs 80%, 14% vs 76%, respectively; log rank P < 0.001).

CONCLUSION

HCC recurrence was low at 8.4% in this contemporary Australian cohort, however it significantly impacted post-LT survival. Further studies are required to confirm predictors of recurrence and improve recipient outcomes.
Global transplantation: Lessons from organ transplantation organizations worldwide
Authors: Symeou Solonas , Avramidou Eleni , Papalois Vassilios , Tsoulfas Georgios
Published: November 2024

Although national transplant organizations share common visions and goals, the creation of a unified global organization remains impractical. Differences in ethnicity, culture, religion, and education shape local practices and infrastructure, making the establishment of a single global entity unfeasible. Even with these social disparities aside, logistical factors such as time and distance between organ procurement and transplantation sites pose significant challenges. While technological advancements have extended organ preservation times, they have yet to support the demands of transcontinental transplantations effectively. This review presents a comparative analysis of the structures, operational frameworks, policies, and legislation governing various transplant organizations around the world. Key differences pertain to the administration of these organizations, trends in organ donation, and organ allocation policies, which reflect the financial, cultural, and religious diversity across different regions. While a global transplant organization may be out of reach, agreeing on best practices for the benefit of patients is essential.

Grass pellet is an alternative method for forage preservation for the dry season. Using industrial residues such as brewer’s yeast and soymilk residue as additives also helps gain more nutritional value for grass pellets. This research aims to study 1) pellet quality (fines particle and Pellet Durability Index, PDI), and 2) nutritional value and dry matter ruminal digestibility (in vitro) of Pennisetum purpureum cv. Mahasarakham grass pellets supplemented with brewer’s yeast (0, 5%) and soymilk residue (0%, 5%, and 10%). The resulting data concerning nutritional values shows that the grass pellet supplemented with 10% soymilk residue and 5% brewer’s yeast had the highest (P<0.05) crude protein (19.99%) and the grass pellets supplemented with 10% soymilk residue only and the grass pellets supplemented with 10% soymilk residue and 5% brewer’s yeast had the highest ruminal dry matter digestibility (in vitro) which were 58.86 and 60.92% (P<0.05), respectively. In addition, the results show that the storage period did not affect fine particles (P>0.05). Brewer’s yeast and soymilk residue supplementation at different levels can improve the PDI of grass pellets to 98.09-99.87% (P<0.05) which is higher than the grass pellets without brewer’s yeast and soymilk, of which residue is equal to 93.22-96.77%. Moreover, grass pellets were supplemented with brewer’s yeast and soymilk residue at different levels had a percentage of fine particles in the range of 0.25% to 1.39% which is lower than grass pellets without brewer’s yeast and soymilk residue (2.46-4.08%, P<0.05).

When disaster strikes, relief organizations experience an immediate need to supply necessities such as food, water, and medical supplies. Resource demand calculation is vital for relief organizations to efficiently mitigate the impact of disasters. Although large humanitarian organizations have private demand estimators, a plethora of local organizations that respond to disasters worldwide lack access to a demand calculator. Academic articles have introduced mathematical models for disaster needs analysis, but their findings and resulting calculators have remained largely limited to the academic community due to the lack of applicable technology. To address this gap between research and technology, the MedicAid Disaster Estimator (MADE), a user-friendly and accessible website was created to forecast the demand for water, food, and medicine in a natural disaster. The website utilizes static calculations to scale per person/ per day recommendations of water, food, and medication to the user’s specified number of people and days. The scale factors, or per person/per day recommendations, were informed by credible industry leaders such as the World Health Organization, Sphere, the European Association of Hospital Pharmacists, the World Food Program, and the United Nations International Children's Emergency Fund to ensure that calculations are reliable. HTML and CSS were used for front-end web development, and Python was used for back-end development. Industry experts were interviewed to inform the scope and future directions.

The aims of the study were to investigate prevalence and severity of dental erosion, and its related etiological risk factors and habits among students of university of Diyala. A cross-sectional survey of 404 university of Diyala undergraduate students, ages 18 to 22, was carried out. The participants were split into four groups: First Academic Stage (96), Second Academic Stage (133), Third Academic Stage (91), and Fourth Academic Stage (84). Before the exam began, general information and questions were captured in a unique form designed for data recording. Students also signed an informed permission form indicating their willingness to participate in research before the exam began. The prevalence and severity of dental erosion were classified for each tooth using the basic erosive wear examination (BEWE). The erosive wear criterion for each surface, tooth, and sexton ranges from 0 to 3. In this recent study females were higher percentage of dental erosion 56.9% than males 43.1% in score 0 of BEWE, also females were higher percentage of dental erosion in score 1, score 2 and score 3. Age 18 has a larger percentage of erosion (7.8%) in score 1 and no erosion in score 3, however age 19 has the highest score (18.2%) compared to the other age groups. Higher percentages in score 2 were 28.4% and 33.3%, respectively, for those aged 20 and 21. The percentage of degradation was higher in score 1 42.7% at age 22. Severe erosion was found in females than males, the enamel layer appears to be more impacted by tooth erosion as indicated by scores 1 and 2, which were determined by the BEWE index.

Authors: Vermeulen Jasper , Caldwell Glenda , Teixeira Müge , Burden Alan , Guertler Matthias
Published: November 2024

This scoping review explores human factors that enrich the design of Human-Robot Collaboration (HRC) beyond the traditional focus on ergonomics and safety. As Industry 5.0 shifts towards a human-centric perspective, understanding the multifaceted interactions within socio-technical systems becomes crucial. The review investigates diverse fields, including design, psychology, and engineering, to identify human factors influencing the successful integration of Collaborative Robotics. The research findings confirm the need and potentiality of using the holistic lens of human factors to illuminate human-centric needs in HRC designs. Moving beyond quantitative measures, the study advocates for qualitative insights to inform the design of HRC and enhance worker conditions through individualised and contextualised experiences of collaborating with cobots. The findings contribute to advancing the understanding of HRC’s complexity and underscore the significance of user-driven perspectives in future research and design efforts.

Published: November 2024

This article offers the perspectives of adults with intellectual disability on how future trends, particularly in social robotics, but also in collaborative robotics, can be co-designed inclusively. These perspectives are offered through research findings as well as researchers’ reflections from co-design and exploratory projects where the research team has engaged adults with intellectual disability in formal and informal learning activities led by social robots. We propose that future work can adopt the social model of disability and a human-rights approach to inclusive technology design by positioning research in a way that respects people’s unique interests and competencies, understands the role of support networks, and engages with communities that celebrate human connections. We provide practical insights into inclusive research approaches and considerations for protocols that meet the requirements of the Australian National Statement on Ethical Conduct in Human Research.
Knee deep in the hoopla: rebuilding our cities beyond rocks and walls. A review of human-need satisfaction during the COVID-19 pandemic.
Authors: Guillen-Hanson Georgina , Thibault Mattia
Published: November 2024

Play in, with, and within the city is a topic that includes notions such as our right to the city and the challenges that current urban layouts and settlements largely determined by socioeconomic circumstances bring about. Through the lens of Gehl’s Urban Quality Criteria and Max-Neef’s Human Development Scale, this paper explores the evidence of how playfulness enabled the satisfaction of human needs as a part of the adaptation process to the ”new” interactions with and within the city, taking the dynamics that emerged after the implementation of the COVID-19 pandemic as a reference. This paper argues that issues hindering our right to the city can be reframed and understood differently from a human-need satisfaction approach. This appreciation can help harness the pandemic’s learnings about play in urban environments, contextualize them among ongoing global crises (i.e., war in Europe, climate change), and support reshaping relationships with and within the city inspired by playfulness.

Field studies were conducted to test the effects of different fertilization regimes on insect pest abundance and grain yields of soybean, as well as on their profitability in the Guinea Savannah zones of Ghana. A total of five fertilization regimes were tested, and these were: 250 kg ha-1 TSP (46% P2O5 or 20%P) applied at sowing; 250 kg ha-1 YARA Legume II (4%N, 7.9%P, 10.8% K, 31%CaO (insoluble), 6%CaO (soluble), 3% MgO, 3%S, 0.075% B) applied at sowing; 250 kg ha-1 YARA Legume II applied at four weeks after sowing (WAS); 65kg ha-1 Nitrabor (15.45% N, 26%CaO, 0.3 B) applied at sowing plus 185 kg ha-1 YARA Legume I (0 % N, 7.9% P, 10.8% K, 31% CaO (insoluble), 4%S, 2% MgO) applied at 4WAS; 185 kg ha-1 YARA Legume I applied at sowing plus 65 kg ha-1 Nitrabor applied at 4WAS. The experiments were laid in randomized complete block designs with three replicates. Fertilization enhanced soybeans’ ability to overcome pest infestations, with plants treated with Nit-65+YLI-185 and YL II-250 + 0 Fert recording lower pest populations and significantly lower pest damages compared to the unfertilized plot. Fertilizer application increased soybean yield by 2269 kg ha-1 in the on-station experiment and by 1334 kg ha-1 in the on-farm experiment. In the on-station experiment, fertilizer use efficiency ranged from 5.5 kg grain per kg fertilizer applied at the 250 kg ha-1 YARA Legume II at 4 WAS to 12 kg grain per kg fertilizer applied with the 65kg ha-1 Nitrabor at sowing plus 185 kg ha-1 YARA Legume I at 4WAS. A similar observation was made in the on-farm experiment but with lower values. Phosphorus use efficiency followed a similar pattern as in the fertilizer use efficiency in both the on-station and on-farm experiments. The highest value cost ratio was attained with 65kg ha-1 Nitrabor at sowing plus 185 kg ha-1 YARA Legume I at 4WAS treatment in both the on-station and on-farm experiments, indicating the potential of increasing the productivity of soybean and the income of farmers in northern Ghana through the regime of fertilization.

The sol-gel self-ignition method has successfully synthesized a series of homogenous perovskites La1-xBixFeO3 (x=0.0, 0.2, 0.4, 0.6, and 0.8) nanoparticles. Rietveld refinement results from XRD patterns revealed no secondary phases in pure and Bi-substituted LaFeO3 samples. The structural transition from orthorhombic at x = 0.0 until x=0.6 (space group Pbnm) to rhombohedral at x=0.8 (space group R3c) was observed. Lattice parameter values increase slightly with Bi concentration due to the substitution of Bi in the LaFeO3 structure. The average crystallite size D was found to vary between 19 nm and 50 nm. The combination of XRD and SEM demonstrated that the prepared Bi-doped LaFeO3 is a single-phase perovskite with a relatively homogeneous particle size distribution. SEM images revealed quasi-spherical particle shapes. FTIR spectra identify the metal oxide bending vibrations at about 536 cm‒1 and 717 cm‒1 attributed to Fe-O and La-O bonds, respectively. No significant effect of Bi substitution from 0% up to 60% on crystal volume was observed, as confirmed by FTIR spectroscopy, which showed no shift in La/Fe-O bending vibration modes with increasing Bi content. The obtained results indicated that the Eg values exhibited a monotone decrease with an increase in Bi ratio. The band gap values varied from 2.2 eV for pure LaFeO3 to 1.85, 1.76, 1.54 and 1.35 eV for the substitutions of 20%, 40%, 60% and 80% respectively. Hence, the sample La0.2Bi0.8FeO3 with the small band gap value can be used as a promising candidate in solar cell applications.

In order to dye cellulose or regenerated cellulose with natural dyes, toxic metal mordants are generally employed. In response to this issue, the novel bifunctional cationic agent was pretreated to modify modal (regenerated cellulose) fabric prior to dyeing to enhance the fiber-dye affinity. The cationization reaction was carried out using a compound containing bicationic sites, N,N'-(oxybis (ethane-2,1-diyl))bis(3-chloro-2-hydroxy-N,N-dimethylpropan-1-aminium. This unique cationic agent is capable of producing nonvolatile amine and has no odor problem. The successful cationic modification was confirmed through FTIR spectroscopy and zeta potential measurement. The cationized process was optimized at a cationic and sodium hydroxide concentration of 90 and 20 g∙L‒1, respectively, with a duration of 5 h. The modified modal fabric significantly enhanced its dyeability with the extract from spent coffee grounds, resulting in deep brown colors. The cationized sample's color strength was noticeably improved. Cationized samples demonstrated better color fastness to washing than untreated samples. Crock fastness was comparable, except the light fastness at high dye concentrations was slightly lower. By utilizing cationization, it offers a promising and sustainable approach enhancing the dyeing with natural dye for green textile coloration.

Authors: SUWANREE Siraprapra , KNIJNENBURG Jesper T.N. , ÖLҪER Emirhan M. , JETSRISUPARB Kaewta
Published: November 2024

The disposal of vinasse, a nutrient-rich by-product of ethanol production, is challenging because of the low pH and emissions of harmful gases and smells. Here, biochars were produced by pyrolysis of mixtures of filter cake and vinasse (0.25 w/v to 1 w/v) at 550℃. The effects of filter cake to vinasse ratios on the biochar yield, pH, ash content, total nutrient (P, K, Ca, and Mg) content, and nutrient availability were investigated. Increasing the filter cake to vinasse ratio increased the biochar yield and ash content and lowered the biochar pH from 10.3 for 0.25-BC to 8.2 for filter cake biochar (FC-BC). Lower filter cake to vinasse ratios increased the total K content from 7.9 g∙kg‒1 for FC-BC to 75.9 for 0.25-BC. Nutrient recovery in the biochars was high (79.5% to 130.2%). Whereas P, Ca, and Mg extractability in water was <5%, the K extractability was 80% for 0.25-BC and decreased to 7.6% for FC-BC. Extractability of K, P, Ca, and Mg in 2% formic acid from vinasse-containing biochars was high (>50%). These results highlight the potential suitability for use in agricultural applications. Conversion of vinasse into value-added biochar could reduce waste treatment cost and improve soil health.

O estudo analisou o panorama da Profilaxia Pré-Exposição (PrEP) no Brasil entre 2019 e 2024. A pesquisa foi motivada pelos desafios enfrentados na implementação da PrEP, especialmente entre populações vulneráveis, como homens que fazem sexo com homens (HSH), mulheres transgênero e jovens. O objetivo geral foi demonstrar um panorama da PrEP no Brasil, nos últimos cinco anos, identificando marcadores sociodemográficos e étnico-raciais dos usuários, continuidade e descontinuidade da profilaxia pelos usuários, e abrangência geográfica da oferta de PrEP no Brasil. A metodologia baseou-se em análise de dados secundários extraídos de painéis epidemiológicos públicos, boletins oficiais e estudos do Instituto ImPrEP. Os resultados indicaram um aumento expressivo no número de usuários de PrEP, de 18.853 em 2019 para 157.890 até outubro de 2024. Contudo, observou-se uma adesão média de 70%, com descontinuidade de uso em cerca de 30% dos casos. As populações com menor escolaridade, jovens entre 18 e 24 anos e pessoas negras apresentaram menor adesão e maiores taxas de abandono. Regionalmente, as disparidades refletem a distribuição desigual de unidades dispensadoras de medicamentos e a concentração de serviços em áreas urbanas. A pesquisa conclui que, apesar dos avanços no acesso à PrEP, persistem desigualdades estruturais e barreiras relacionadas a estigma, discriminação e falta de acesso aos serviços de saúde. São necessárias políticas públicas mais inclusivas e abordagens integradas para enfrentar essas barreiras, promovendo maior equidade e efetividade no combate à epidemia do HIV no Brasil.

Published: November 2024

Com a problemática ambiental atual caracterizada especialmente pela intensificação dos eventos climáticos, surge a necessidade de buscar formas alternativas de energia. Com isto, a produção de biodiesel a partir de fontes renováveis tem ganhado destaque. As microalgas são organismos unicelulares, capazes de realizar fotossíntese, matéria-prima com alto potencial para produção desse tipo de combustível. Esses microrganismos apresentam em sua composição um alto teor de lipídeos, essencial na produção de biodiesel. Neste sentido, esta revisão bibliográfica busca explorar as vantagens da produção de biodiesel a partir da biomassa microalgal, analisando estudos publicados nos últimos 20 anos em bases de dados como ResearchGate, ScienceDirect e Google Scholar. Além disso, este trabalho faz uma análise acerca do potencial das microalgas como fonte de óleo para a produção de biodiesel, e aborda a versatilidade desses seres em diversas aplicações, ao longo dos anos. Os resultados desta revisão demonstram que a produção de biodiesel a partir de microalgas apresenta um grande potencial para mitigar os impactos ambientais causados pela utilização de combustíveis fósseis, além de contribuir para uma transição energética, de forma mais sustentável. Espera-se que esta revisão contribua para o embasamento teórico de futuras pesquisas nas áreas de bioenergia.

A dislexia compreende um transtorno específico de aprendizagem que leva à uma série de dificuldades de aprendizagem, principalmente às relacionadas à aquisição de leitura e escrita. O sujeito disléxico apresenta uma série de características que resultam na dificuldade de decodificação, entendimento de enunciados e incompreensão da leitura. A dislexia não é considerada uma doença, mas os indivíduos disléxicos irão conviver com esse transtorno durante toda vida. Mesmo não tendo cura, é possível aos disléxicos desenvolver várias potencialidades, não podendo sua aprendizagem ser restringida somente às dificuldades. Diante disso, o presente estudo teve como objetivo revisar as possíveis estratégias para que docentes possam levar conhecimento a alunos com dislexia. Não obstante, os objetivos específicos foram conhecer os fatores que dificultam o aprendizado da criança com dislexia e quais as estratégias de ensino que os profissionais da educação utilizam para conduzir o aprendizado. A metodologia utilizada foi a pesquisa bibliográfica, baseada em estudos científicos contidos em sites de busca acadêmica e repositórios institucionais. Dentre os resultados obtidos, denotamos a importância do diagnóstico precoce da dislexia, para que o professor possa efetivar um trabalho individualizado voltado para a aprendizagem da criança disléxica. Esse trabalho contribui para o ensino-aprendizagem de alunos com dislexia, podendo ser uma ferramenta de busca para docentes que lidam com esse transtorno em sala de aula.

Neste estudo, apresentamos a caracterização da pesca e alguns dados biológicos do camarão invasor Macrobrachium rosenbergii (De Man, 1879) coletados na Vila Canivete, no município de Chaves/PA. Os camarões foram coletados em um período de um ano, mas a espécie M. rosenbergii só foi capturada entre julho de 2021 e março de 2022. Para a captura dos camarões, os instrumentos de pesca utilizados foram o matapi, com abertura de 0,5 cm, e a tarrafa, com abertura de 1 cm entre os nós, sempre utilizando o babaçu como isca. Os dados abióticos de temperatura e salinidade foram medidos durante o estudo. A temperatura permaneceu praticamente constante durante todo o período, variando de 27,6 a 28,1 °C, e a salinidade variaram de 0,1 na estação chuvosa (dezembro e março) a 0,7 o/oo no período com pouca chuva (julho a novembro). No laboratório, os indivíduos foram identificados, sexados, medidos e pesados. Neste estudo, 179 indivíduos foram capturados. O número total de fêmeas (72 animais) capturadas durante todo o período foi menor do que o número de machos (107 animais). Em termos de comprimento total médio e peso total, os machos apresentaram números mais altos do que as fêmeas. Das 107 fêmeas capturadas durante o período da pesquisa, 34 (47,2%) não tinham ovos, enquanto 38 (52,8%) tinham ovos. Com relação ao número de fêmeas da espécie M. rosenbergii por mês, foi possível observar que houve predominância de fêmeas ovígeras na maioria dos meses, exceto em outubro de 2021 e janeiro de 2022. A ocorrência de fêmeas em maturação foi observada em todos os meses em que foram capturadas, embora nos meses chuvosos (dezembro e março) tenha havido maior ocorrência. A população da Vila Canivete, no município de Chaves/PA, utiliza ativamente a M. rosenbergii em suas atividades econômicas e no consumo de subsistência. Entretanto, a presença de uma espécie invasora no ambiente causa sérios danos ao ecossistema. Isso torna necessária a criação de planos de manejo e o controle da invasão de M. rosenbergii na província amazônica, a fim de preservar o ambiente natural e a integridade das espécies nativas no ambiente. Além disso, constatou-se que os pescadores de camarão M. rosenbergii precisam de políticas públicas para promover atividades educacionais e pesqueiras, bem como a geração de emprego e renda, a fim de melhorar a qualidade de vida da população local.

No ano de 2021, a participação do agronegócio no PIB foi de 27,4%, sendo o maior resultado apurado desde 2004. Porém, a ampla capacidade de produção e renda no setor pode ser reduzida com uma gestão de custos deficitária. Este trabalho teve como objetivo analisar os dados do Programa Zebu PO: Produção de carne de qualidade com eficiência e sustentabilidade. O experimento compreendeu três fases do sistema de produção animal: 1. recria a pasto no período da seca; 2. recria a pasto no período das águas; 3. engorda/terminação no confinamento. Foi elaborado o Demonstrativo de Resultado Econômico, apurou-se o fluxo de caixa dos custos, calculou-se os ponderadores técnicos-econômicos e foi analisado na forma gráfica com uma linha de tendência para análise do resultado individual. O sistema de produção apresentou viabilidade econômica, receita bruta de R$528.797,00; lucro por arroba de R$109,30; custo por arroba de R$203,7 e uma margem de 34,9%. Em ordem decrescente, os maiores custos foram relacionados aos seguintes aspectos: nutricional, forrageiro e sanitário. Houve oscilação média de necessidade de capital de R$20.000 nas duas primeiras fases e de R$65.000 para cobrir gastos na terceira, evidenciando a importância de se ter um capital de giro.
