Authors: Maulana Prawiro Wahyu , Rosi Subhiyakto Egia
Published: August 2024

In the current digital era, Human Resource Management (HRM) has undergone significant transformation with the advent of technology, including employee attendance applications. These applications replace inefficient and error-prone manual methods, facilitating effective attendance, leave, and monitoring of working hours. This study aims to apply a user-centered design (UCD) approach to developing an employee attendance application to enhance user experience (UX). Evaluation using the System Usability Scale (SUS) revealed a usability score of 86.37, classified as "Excellent." This score reflects positive user reception and underscores the importance of user-focused approaches in development. This research shows how user-tailored features can improve attendance management efficiency and effectiveness by aligning the application with user workflows. Despite the positive results of this study, recommended to continue periodic design iterations with regular user feedback to improve usability and satisfaction.

Authors: Tuazon Brian J. , Dizon John Ryan Cortez
Published: August 2024

For the past few years, the adoption of 3D printing technology has benefited various manufacturing industries, including the furniture making industry. However, this adoption has been greatly seen in industrialized countries and lacking in developing countries. Therefore, to understand fully the capability of 3D printing and its benefits, this paper review discusses recent applications of 3D printing in the furniture industry and assesses the potential it can bring for developing countries’ furniture making industry, specifically in the Philippines and other developing countries in Asia. In addition, the drawbacks it brought to the industry, and the challenges that needed to be addressed are also discussed in the paper.  The paper covers various 3D printing technologies such as material extrusion, sheet lamination, powder bed fusion, and vat photopolymerization, along with different materials currently used in the furniture industry. Numerous notable examples of applications of 3D-printed furniture are also presented. Based on the review paper, it was found that the most common 3D printing technologies used in the furniture industry are Material Extrusion (MEX) and Powder Bed Fusion (PBF) specifically Fused Deposition Modelling (FDM) and Selective Laser Sintering (SLS), respectively. The most common 3D printing materials used are Polyamide (PA), Polylactic acid (PLA), and recycled Polyethylene terephthalate glycol (PETG). The paper also discusses the possible adoption of 3D printing in developing countries and explores its potential to innovate traditional furniture manufacturing processes.
Challenges in evaluating Islamic education learning in schools: Implications for educational objectives
Authors: Arlinda Arlinda Ayu Diah Arfani
Published: August 2024

This research was driven by numerous issues identified in the implementation of Islamic Religious Education (Pendidikan Agama Islam, hereinafter PAI) in schools, which diverge from the intended goals of Islamic education, particularly in fostering moral development and student skills. The primary objective of this study was to analyze the challenges in evaluating PAI learning in schools and to understand its implications for the overarching goals of Islamic education. Employing a qualitative approach, this study utilizes a descriptive-analytical method through library research. The data validity was established through the examination of various relevant sources, including journals, scholarly articles, books, and documents pertinent to the evaluation of PAI learning. The findings reveal significant problems, particularly in the neglect of affective and psychomotor domains, with an overemphasis on cognitive assessment. The assessment methods often fail to reflect the intrinsic values or spirituality, are inconsistent, and tend to be subjective. These issues manifest in the form of assessments that do not adequately capture the moral and ethical dimensions that are central to Islamic education. Consequently, these shortcomings hinder the achievement of the primary goals of Islamic education, which include the cultivation of exemplary moral character and the recognition of diverse student skills and abilities. Furthermore, the inconsistency and subjectivity in assessment practices undermine the reliability and effectiveness of the educational outcomes. Addressing these issues is crucial for aligning the evaluation methods with the holistic objectives of Islamic education, thereby ensuring a more comprehensive development of students' intellectual, moral, and practical competencies.
Human Rights Violations and Corporate Criminal Liability: An Analysis of the New Indonesian Criminal Law
Authors: Amiati Mia , Adhryansah Adhryansah , Prihandono Iman
Published: August 2024

In light of the increasing role of corporations in facilitating gross human rights violations, this article seeks to evaluate the implementation of the Indonesian Criminal Law in addressing corporate criminal liability. Notably, the recently amended Indonesian Criminal Law recognizes corporations as subjects of criminal law, but Law No. 26 of 2000, which regulates gross human rights violations, does not. Consequently, this research specifically scrutinizes the Indonesian Criminal Code, Law No. 26 of 2000, and international legal standards to answer the issues: rules of aiding and abetting under international criminal law and the applicability of corporate culture theory, and the implementation of Indonesian Criminal Law in addressing corporate criminal liability for gross human rights violations. Examining these issues relies on three methodologies, namely the statutory approach, conceptual approach, and case approach. The results of this article uncover that the recognition of corporations as subjects under the new Indonesian Criminal Code and rectification of the ratione materiae of Law No. 26 of 2000 open the avenue for corporations to be held criminally liable for gross human rights violations based on aiding and abetting. Furthermore, the theory of corporate culture envisaged in the new Indonesian Criminal Code renders the plausibility of holding corporations liable if they are deemed to cultivate a culture that pushes or encourages a gross human rights violation.

Published: August 2024

The enactment and application of the Electronic Transaction Information Law are pivotal for delineating the appropriate boundaries for exercising freedom of opinion and expression within Indonesia's digital sphere. According to reports from international digital rights research and advocacy organizations, online media journalists and human rights activists frequently encounter direct pressure and cyber harassment. This article explores the balance of freedom of expression in Indonesia's digital domain to ensure a secureenvironment for human rights defenders advocating for human rights. This study uses socio- legal methodologies to draw on data from literature reviews and in-depth interviews. It underscores the need for regulatory reforms to define prohibited hate speech explicitly. SAFENet documented 153 cyber-attacks in Indonesia in 2022, predominantly targeting civil society groups, students, activists, and journalists. Additionally, the National Committee on Human Rights reported that 52% of attacks on human rights defenders occurred in the digital realm. While the protection of digital democracy varies by nation, Indonesia must establish aninstitution responsible for properly enforcing the ITE Law alongside an independent monitoring mechanism and related policies. Such institutions, including those dedicated to human rights defenders, uphold human rights and demonstrate a commitment to the principles of freedom, respect, equality, and dignity within society.

Comparing nuclear DNA content, pollen viability, pollen production and seed retention of lavender and lavandin
Authors: Baydar Hasan , Tuğlu Ümmü
Published: August 2024

Lavender (Lavandula spp.) is one of the most widely grown essential oil crops in the world. This study aimed to determine the nuclear DNA contents using flow cytometry, pollen viability using TTC (2,3,5-Triphenyl Tetrazolium Chloride) and IKI (Iodine Potassium Iodide) tests, pollen production quantities using hemacytometric method, and seed retention rates per spike and flower of lavender (L. angustifolia var. Raya) and lavandin (L. intermedia var. Super) grown under ecological conditions in Isparta province of Turkey. The nuclear DNA contents were 2.11 and 2.54 pg 2C-1, respectively in the lavender and lavandin cultivar. The flowers of the lavender cultivar produced abundant pollen grains (average 5800 pollen per flower and 1450 pollen per anther) with high viability (60.65-65.05%) and seed retention rate per spike (91.57% on average). The lavandin cultivar, which had very low pollen viability (1.08-3.32%) and pollen grains (average of 2350 pollen per flower and 587.5 pollen per anther) gave very low seed retention rates per spike (0.60% on average). While each flower had four ovaries with the potential to produce four nutlets, lavandin flowers produced only trace numbers (0.15% on average) of seeds. As a result, the lavandin cultivar had more nuclear DNA content, longer stem and spike, smaller size but more numerous flowers, less and lighter anthers, lower pollen grains and viability, and vey few inviabile seeds compared to the lavender cultivar. It has been observed by eye that honey bees do not visit lavender and lavandin flowers for collecting pollen, but solely for collecting nectar.

Published: August 2024

The cotton mealybug, Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae), is a significant economic pest with a global distribution. Despite the increasing volume of literature on mitochondrial genome sequencing, complete mitochondrial genome sequences have not been reported for P. solenopsis yet. Here, we assembled the complete mitochondrial genome of P. solenopsis using high throughput DNA sequencing technology. The genome is 14,831 bp in length and is comprised of 37 genes: 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, and two ribosomal RNA (rRNA) genes. The total length of all PCGs is 9,678 bp, accounting for 65.2% of the overall mitogenome. Among the PCGs, atp8 is the smallest gene (99 bp) and nad5 is the largest (1,593 bp). Of the 13 PCGs, seven (nad3, cox3, atp6, atp8, cox2, cox1, nad2) are encoded on the majority strand (J-strand), while six (nad1, nad6, cob, nad4L, nad4, nad5) are on the minority strand (N-strand). The analysis revealed a predominant A+T base composition, making up 90.3% of the total genome. However, the non-coding regulatory control region (CR) is missing due to the non-overlapping endpoints of the linear assembly. This assembly provides comprehensive information for investigating the evolutionary relationships between scale insects and for the precise identification of insects.

Habilidades docentes para o multiletramento digital na ubiquidade
Authors: Alencar de Mesquita Ofelia
Published: August 2024

Por séculos, as linguagens oral e escrita, como também o comparecimento físico alcançaram as modalidades de levar o conhecimento. Na atualidade, dispositivos móveis - como notebooks, tablets e smartphone - com suas múltiplas expressões, permitem reconfigurar as dimensões das salas, como das próprias aulas. Expandem-se, então, as discussões sobre os saberes pedagógicos associados às realidades das variadas possibilidades de leitura e escritas virtuais, sobretudo quando se considera a ubiquidade como fenômeno da cibercultura. Este ensaio adotou como percurso metodológico a pesquisa bibilográfica com o objetivo  de análisar acerca das habilidades docentes requeridas para o multiletramento digital, sob o influxo dessas tecnologias digitais ubíquas. Destaca-se o fato de que a inserção das tecnologias digitais na esfera educativa tende a se adensar, por conseguinte, os multiletramentos digitais dos professores são cada vez mais dirigidos para as singularidades da rede, inclusive os críticos em relação às mensagens e suas linguagens.  Depreende-se a existência de significativas ligações entre a aquisição de multiletramentos digitais e a compreensão docente acerca dos códigos multimidiáticos, como habilidades expressas, também, na incorporação de práticas interativas, integrativas e autorais on line.

Published: August 2024

Objective: To compare the postoperative outcomes while using direct true lumen approach versus conventional cannulation approach in management of acute type-A aortic dissection patients. Study Design: Randomized Clinical Trial. Setting: Department of Vascular Surgery, Combined Military Hospital, Rawalpindi. Period:  1st June 2022 to 31st December 2022. Methods: A total of 22 patients age more than 18 years who presented in CMH Emergency Department with acute type A aortic dissection were included in this study. In group A (11 patients) were managed with direct true lumen cannulation while in group B (11 patients) were managed with conventional (axillary/femoral) cannulation. In both groups intra-operative parameters like procedure time, mean time of cardiopulmonary bypass, cross clamp and circulatory arrest time were measured. In both groups, outcome was measured in terms of occurrence of multi-organ failure, acute kidney injury, arrhythmias on ECG and in-hospital mortality. Data was analyzed using SPSS 26. Results: Mean age of our patients were 43.36±2.16yrs in group A while 43.36±2.94yrs in group B. Male gender predominates in both groups (gp A- 81.8% & gp B-90.9%). We found no difference of statistical significance between two groups in terms of various intra-operative parameters like mean duration of procedure in group A was 428.15min and in group B was 427.36 min. Similarly mean circulatory arrest time was 31 min in group A and 29.09 min in group B. Patients in “direct true lumen cannulation” group had significantly shorter duration of intubation. In terms of post-operative outcomes, multi-organ failure occurred in 1 (9.09%) patient in group A while it occurred in 3(27.27%) patients in group B. In hospital mortality occurred in 2(18%) patients in group A as compared to 4(36%) in group B. So better results were observed in “direct true lumen cannulation” group as compared to “conventional (axillary/femoral) cannulation” group. Conclusion: In our study, acute type-A aortic dissection patients who had undergone direct true lumen cannulation during operative management showed better post-operative outcomes.

Authors: Saleh Saadat Afridi  , Sara Riaz
Published: August 2024

Objective: This study aimed to assess the impact of anaemia on exercise capacity in Chronic Obstructive Pulmonary Disease (COPD) patients by comparing the six-minute walk distance (6MWD) between anaemic and non-anaemic individuals. Study Design: Cross-sectional study. Setting: Department of Pulmonology, Khyber Teaching Hospital, Peshawar. Period: November 15, 2019 until May 14, 2020. Methods: This study included 162 COPD patients aged 40 to 70 years. Exclusion criteria encompassed any lung pathology other than COPD, malignancy, cardiac pathology, or conditions affecting hemoglobin levels. The 6MWD test was utilized to evaluate exercise capacity. Data analysis utilized SPSS Version 25.0, with descriptive statistics employed to summarize the demographic and clinical characteristics of the study population. A significance level of ≤0.05 was used to determine statistical significance. Results: The mean age of participants was 62.07 years, with a mean hemoglobin level of 12.63 gm/dl. The average 6MWD was 234.78 meters. Among the subjects, 40.74% were male. Anaemic patients had a significantly lower 6MWD (190.99 ± 95.44 meters) compared to non-anaemic patients (278.58 ± 100.17 meters; p ≤ 0.001). There were no significant differences in COPD duration, age, body mass index, or smoking status between the two groups. Conclusions: Anaemic COPD patients demonstrated a significantly reduced exercise capacity, covering approximately two-thirds of the distance non-anaemic patients did on the 6MWD test. These findings suggest that early diagnosis and management of anaemia in COPD patients could potentially improve their exercise tolerance and overall quality of life.

Objective: To evaluate the association between JAK2 mutation status, PMF disease characteristics, and prognostic features as assessed by the DIPSS Plus scoring system. We analyzed clinical and laboratory data from a cohort of PMF patients to determine the influence of JAK2 mutation on disease presentation and progression. Study Design: Cross Sectional study. Setting: Department of Pathology and Oncology, King Edward Medical University/Mayo Hospital, Lahore. Period: December 2022 to December 2023. Methods: Total 27 patients with PMF were enrolled in the study by non-probability consecutive sampling technique. Patients were diagnosed according to WHO 2016 criteria. CBC and serum LDH were performed by automated hematology and chemistry analyzers respectively. Real-time PCR was used to identify the JAK2 mutations. Risk stratification was done by DIPPS criteria. Data was analyzed by Microsoft Excel 2010. Mean and standard deviation was calculated. Student ‘T’ test was used for comparison of mean between two groups with and without JAK2 mutations. Results: Out of 27 patients 66.6% were males and median age was 59 years. Splenomegaly was the dominant clinical feature accounting for 51.4% with mean splenic span of 17.8±2.91cm. Mean LDH levels was 872.5±324. JAK2 positive expression was found to be significantly correlated with increased splenic span and raised LDH levels with P-value of <0.05. Risk stratification showed 11% patients were in high-risk group. Conclusion: Marked enlargement of spleen and raised in serum LDH levels indicate that patients in our settings had clinically advanced stage of the disease. Apart from this manifestation of JAK2 V617F mutated patients indicated a more aggressive phenotype of the disease.

Politics and Its Materializations as a Social Fact
Authors: Rosa Mário Rodrigues Fleury
Published: August 2024

Entender o que define um fato social e sua correspondência na sociedade é vital para qualquer tipo de análise sociológica. O conceito criado por Emile Durkheim é caracterizado por três fatores: Exterioridade, coercitividade e generalidade (Karlsson, 1999). Assim, até mesmo a política e suas respectivas materializações podem ser agrupadas nessas três categorias, tendo como exemplos modelos governamentais ditatoriais, totalitários ou mesmo nas relações políticas cotidianas que temos com as autoridades. Ao final, após diversas análises, foi possível deduzir que a política, em todas as suas esferas, pode ser considerada um fato social extremamente presente em nossas vidas, bem como muito arraigado.
Proving the Joule Effect Through Electronic Circuits

Published: August 2024

O objetivo desse experimento foi comprovar, quantificar e analisar, por meio da prática experimental, a presença e os respectivos valores numéricos do efeito Joule e da potência em um circuito eletrônico, composto por quatro subcircuitos eletrônicos. Na montagem desses quatro subcircuitos, utilizamos um Breadboard - dimensões 16,9 cm x 5,5 cm -, resistores de 1 k e 270, LEDs (Light Emitting Diode) de vários tamanhos, cores e resistências, jumpers de vários tamanhos e uma bateria de 9 V. No processo de quantificação do calor presente nos quatro subcircuitos, foram utilizadas as fórmulas estudadas no campo da engenharia e da física, relacionadas a potência, resistência e corrente. Os resultados finais mostram que, apesar dos pequenos valores de corrente, há liberação de calor pelo sistema, bem como uma relação proporcional entre resistência e liberação de calor, sendo também notável que os circuitos feitos em paralelo tendem a ter uma resistência menor, consequentemente mais calor liberado. Por fim, é possível concluir que as leis da termodinâmica e da física como um todo podem ser analisadas, computadas e comprovadas, mesmo em circuitos simples
Comprehending the Relationship Between Photon and Matter and Its Experimental Applications
Authors: Rosa Mário Rodrigues Fleury , Archontovasilis Filippos Panteleimon
Published: August 2024

O fóton, uma partícula sem massa e sem carga, há muito tempo deixa os físicos perplexos devido à sua natureza dupla de onda e partícula. No início do século XX, foi demonstrado que o fóton, assim como outras partículas, exibe simultaneamente comportamentos de onda e de partícula. Este artigo tem como objetivo explorar a interação dos fótons com a matéria e abordar questões relativas à sua relação. Pesquisas experimentais revelam interações significativas entre fótons, especialmente em frequências mais altas, e vários materiais, exemplificadas por fenômenos como os efeitos fotoelétrico e Compton, bem como a produção de pares. Embora esses exemplos sejam peculiares à física quântica e possam parecer distantes da nossa realidade, o estudo baseia-se no trabalho de pesquisadores da Universidade de Brasília (UnB), que utilizaram interações fóton-matéria no tratamento de feridas de pé diabético, ilustrando como o conhecimento quântico pode salvar e melhorar vidas. Essa abordagem interdisciplinar ressalta não apenas a existência dessa relação, mas também a implementação prática da física quântica na sociedade.

Neste artigo, apresentamos um relato de experiência, a partir de uma pesquisa de mestrado em andamento, sobre uma pro-posta desenvolvida em uma escola pertencente ao Programa Ensino Integral, no contexto de uma disciplina eletiva. A partir do tema orçamento familiar foi solicitado aos estudantes que realizassem uma busca dos valores dos itens que compõem a cesta básica referente aos anos de 2012 e 2021. Na sequência, estudantes observaram o impacto da cesta básica no salário mínimo a partir de recortes disponibilizados por nós e se questionaram sobre o estado mais rico do Brasil, São Paulo, não possuir política pública para pautas coletivas, como educação e alimentação. Assim, com este trabalho realizado, vislumbramos a possibilidade de propor tarefas investigativas com a matemática em ação, de modo que possibilite aos estudantes do Ensino Médio refletir sobre temas relevantes para sua formação como cidadão e problematizar temáticas ligadas à Educação Financeira.

De bustos a retratos: os Doze Césares para além de doze faces
Authors: Carminati Luis Henrique
Published: August 2024

As imagens fazem parte da comunicação humana muito antes da invenção da escrita. A construção de um discurso imagético delineia camadas de significados, de sentidos e identificação. Logo, a imagem consegue estabelecer redes de comunicação a partir de seu contexto produtivo e temporalidade, mas também através da reinterpretação e releitura em outros ambientes e conjunturas que pode adicionar novas camadas. Dessa forma, o livro "Doze Césares: imagens de poder do mundo antigo ao moderno" - objeto desta resenha - aborda as diferentes interpretrações e releituras produzidas sobre os Doze Césares, a família e o sistema imperial, compreendendo assim seus usos e interlocuções com outras temporalidades, que por meio dessas imagens buscavam elaborar formas discursivas alinhadas com interesses específicos.
Linguagem visual em moedas: as cunhagens marianistas da República romana (101-97 AEC)
Authors: Ayres Gisele Oliveira Barbosa
Published: August 2024

Dentre as cunhagens conhecidas da República romana, há um conjunto de moedas, produzidas entre 101 e 97 AEC, cuja emissão é atribuída aos seguidores do general e político Caio Mário. As peças possuem características que são recorrentes às cunhagens do período, porém, simultaneamente, ostentam algumas peculiaridades. O presente artigo trabalha com a hipótese de que esses elementos peculiares, que as distinguem das cunhagens padrão da época, não são aleatórios, mas estão associados ao projeto de poder e memória daqueles que a produziram. Essas características traduzem um discurso político específico em forma de linguagem visual e são testemunhos que ajudam a reconstituir a trajetória de um grupo que atuou na vida pública da República romana. Após breves considerações sobre contexto e materialidade, a análise se concentrará na leitura e interpretação das imagens nas moedas.
A estátua de Jano na 'Aedes Ianus Geminus': antiquarismo e a composição de um deus do tempo para Roma
Authors: Pires Thiago de Almeida Lourenço Cardoso
Published: August 2024

Os escritores romanos demarcaram Jano como um dos deuses mais antigos de seu panteão. Tanto o exotismo de sua imagem divina quanto a sua ancestralidade causaram aos romanos uma certa perplexidade: os antiquários republicanos e augustanos tentaram desvendar a natureza do deus mais em tons especulativos e filosóficos do que taxativos. Meu objetivo nesse texto é averiguar como os antiquários configuraram e caracterizaram Jano como deus do tempo com base na principal imagem do deus, a sua estátua na Aedes Ianus Geminus.

Introdução: As cirurgias orais nos indivíduos cardiopatas sob terapia antitrombótica, em uso de medicamentos como antiagregantes plaquetários e/ou anticoagulantes, são sempre um desafio quanto às manobras hemostáticas locais a serem utilizadas. Para que estas cirurgias possam ser realizadas com maior segurança e efetividade, é necessário que cirurgiões-dentistas e cardiologistas mantenham-se atualizados sobre os processos hemostáticos da coagulação. Objetivo: Apresentar os resultados de eficácia e as opções de produtos hemostáticos locais disponíveis no mercado brasileiro, com embasamento científico, para serem utilizados em procedimentos odontológicos invasivos, em especial nos pacientes que apresentam risco aumentado de sangramento. Metodologia: Realizou-se uma revisão narrativa nas bases de dados PubMed, Medline e Google Scholar no período de 01/2009 a 4/2024 com os seguintes descritores: hemostáticos locais, odontologia, cirurgia oral, desordens hemorrágicas, sangramento oral e hemostasia. Resultados: Os resultados obtidos mostram que a variedade de produtos hemostáticos é imensa e de variável indicação de uso, sendo que o ácido tranexâmico é o mais estudado e referenciado. Quanto à disponibilidade no mercado brasileiro, os produtos que têm menor custo são os antifibrinolíticos, seguidos das esponjas hemostáticas e os selantes de fibrina. Conclusão: Todos os produtos têm efeito satisfatório quanto ao seu uso, e indicações adequadas. O custo dos antifibrinolíticos é o mais conveniente para o profissional do Brasil, mas as outras opções podem ser muito efetivas no controle da hemostasia em cirurgia oral.
Sonority Is Not Sufficient: Syllabification and Syllable Patterns in Jordanian Ammani Arabic
Authors: Abu Quba Mohammed Nour , Abu Qub'a Abdallah
Published: August 2024

This study presents a novel approach to syllabification and syllable structure in Jordanian Ammani Arabic (JAA), addressing challenges posed by complex syllable patterns and codas. We show that sonority principles alone, as suggested by earlier research, cannot account for syllable structure in JAA. We introduce a new constraint, the Coda Cluster Requirement (CodaReq), which governs the occurrence of coda clusters in JAA, considering factors such as sonority, markedness, and morphological ones. We propose an algorithm that is better able to syllabify JAA complex syllables, adopting mora sharing and semisyllables, which maintain bimoraicity while accounting for complex onsets and codas. We also show that JAA exhibits characteristics of both VC and C dialects, suggesting an intermediate classification. The proposed algorithm may be extended to account for other Arabic dialects.

In the 1950s, the Furnas reservoir was created, an artificial lake surrounded by hills, for the operation of the Furnas Hydroelectric Power Plant in southeastern Brazil. Along the shores of the Furnas reservoir, there are no meteorological stations, and only three are found at a distance greater than 10 km from the reservoir, which makes it challenging to assess the lake's influence on the local climate. To address this issue, the Regional Climate Model version 5 (RegCM5) was run in convection-permitting (CP) mode for two months, with a horizontal resolution of 1 km, to investigate the near-surface atmospheric circulation patterns around the reservoir. Three numerical experiments were conducted using RegCM5-CP nested in ERA5 reanalysis: a control simulation (CTRL), an experiment where the topography was assumed to be flat throughout the domain (expTOPO), and an experiment where the water body was replaced by vegetation (expVEG). The first month of simulation in each experiment was excluded from the analysis as it was considered a spin-up period. RegCM5-CP has good performance in simulating the diurnal cycle of the 2-m air temperature and reasonable performance for the 10-m wind intensity compared to observed data from three meteorological stations in the domain of simulation (but distant from the reservoir shore). Despite the geographic complexity of the Furnas reservoir, the experiments revealed coupling between lake and valley breezes during the daytime and land and mountain breezes during nighttime in different segments of the reservoir, such as in Guapé (near the dam). However, mountain-valley breezes are more dominant.
