Abstract This article intends to propose a methodology to characterize the Financial (In)Sustainability of Brazilian municipalities − materialized through the Municipal Financial Sustainability Index (ISFM) − as opposed to the methodology suggested by the Proposed Amendment to the Constitution (PEC) No. 188, whose agenda is to incorporate small municipalities considered unsustainable. Regarding the methods, we used quantitative, applied, descriptive and explanatory research, of the bibliographical and documentary type, in addition to descriptive statistics and correlation/linear regression. The results demonstrate that the ISFM is more robust compared to the methodology proposed by the PEC. The Index was applied to 5,570 Brazilian municipalities and the national average resulted in 56%. Most Brazilian municipalities classified themselves as “Sustainable” and the statistical analysis significantly demonstrated the existence of a positive correlation between the variables ISFM and Local Development. The contributions of the work turn to the production of research on the subject, still incipient nationally.

RESUMO Objetivo: Avaliar a correlação entre a religiosidade e o uso de álcool em adolescentes com fissura orofacial. Métodos: Estudo transversal, desenvolvido em um hospital público e terciário brasileiro entre dezembro de 2021 e março de 2022. A coleta de dados foi híbrida, e foram utilizados três instrumentos: Questionário Sociodemográfico, Escala de Religiosidade de Durel e o Alcohol Use Disorders Identification Test. Para a análise estatística foram empregados os testes: qui-quadrado, exato de Fisher, Mann-Whitney e o coeficiente de correlação de Spearman, além das análises de forças de correlação linear e de regressão logística bivariada. O nível de significância adotado para todos os testes foi de 5% (p≤0,05). Resultados: Participaram 370 adolescentes, com média de idade de 15,2 anos (±1,8). Entre eles, 23 (5,4%) usavam o álcool de forma arriscada ou prejudicial. A religiosidade organizacional, não organizacional e a intrínseca foram significativamente menos frequentes entre adolescentes que utilizavam o álcool de forma arriscada ou prejudicial (p=0,005; p<0,001 e p=0,002, respectivamente). Evidenciou-se correlação moderada entre o uso arriscado ou prejudicial do álcool e a religiosidade não organizacional (r=0,31; p=0,002) e a intrínseca (r=0,36; p<0,001). Apresentaram maiores chances de usar o álcool adolescentes do sexo masculino (p<0,001; odds ratio — OR=6,58), com idade mais próxima aos 18 anos (p<0,001; OR=1,37) e que não praticavam a religião (p<0,001; OR=6,48). Conclusões: Adolescentes com maiores níveis de religiosidade organizacional e intrínseca utilizaram menos frequentemente álcool de forma arriscada ou prejudicial, enquanto ser homem, possuir idade mais próxima aos 18 anos e não praticar a religião aumentou a chance de utilizar álcool.

ABSTRACT Objective: To evaluate the correlation between religiosity and alcohol use among adolescents with orofacial clefts. Methods: Cross-sectional study, developed in a Brazilian public and tertiary hospital, between December 2021 and March 2022. Data collection was hybrid, and three instruments were used: Sociodemographic Questionnaire, Durel Religiosity Scale, and the Alcohol Use Disorders Identification Test. For statistical analysis, the following tests were used: χ2, Fisher’s Exact, Mann-Whitney and Spearman’s Correlation Coefficient, in addition to analyses of linear correlation strength and bivariate logistic regression. The significance level adopted for all tests was 5% (p≤0.05). Results: 370 adolescents participated, with a mean age of 15.2 years (±1.8). Among them, 23 (5.4%) used alcohol riskly or harmfully, being more frequent among male adolescents (p=0.001), those of mixed race (p=0.046), attending high school (p=0.011), with no religion (p<0.001), or who did not attend religious services (p<0.001). Levels of organizational, non-organizational and intrinsic religiosity were significantly lower among adolescents with risky or harmful alcohol use (p=0.005; p<0.001 and p=0.002, respectively). There was a moderate correlation between risky or harmful alcohol use and non-organizational (r=0.31; p=0.002) and intrinsic (r=0.36; p<0.001) religiosity. Male adolescents (p<0.001; OR=6.58), closest in age to 18 years (p<0.001; OR=1.37), and non-practitioners of religion (p<0.001; OR=6. 48) presented higher odds of risky or harmful alcohol use. Conclusions: Adolescents with higher levels of organizational and intrinsic religiosity used less alcohol, while males, closest in age to 18 years, and non-practitioners of religion presented higher odds of using alcohol riskly or harmfully.

RESUMO Objetivo: Examinar a associação entre o tempo de tela autorreportado e os sintomas de estresse, ansiedade e depressão em adolescentes. Métodos: Foi realizado estudo com delineamento transversal com 982 adolescentes entre 12-15 anos, matriculados na rede pública de ensino da cidade de Jacarezinho (PR). Para mensurar o tempo de tela, os adolescentes responderam à pergunta: “Considerando um dia típico, quanto tempo você passa assistindo TV, jogando videogame, usando computador ou smartphone?”. O questionário DASS-21 (versão curta) foi utilizado para avaliar os sintomas de depressão, ansiedade e estresse. Análises brutas e ajustadas (idade, sexo e nível de escolaridade materna) entre tempo de tela e indicadores de saúde mental foram realizadas por meio do modelo de regressão linear generalizado, com distribuição de Poisson, adotando a significância de p<0,05. Resultados: Maiores sintomas depressivos foram observados em adolescentes com tempo de tela de 4–6 horas/dia (RP 1,35, IC95% 1,13–1,61) e ≥6 horas/dia (RP 1,88, IC95% 1,62–2,19) quando comparados com seus pares com ≤2 horas/dia. O mesmo foi observado para os sintomas de ansiedade com tempo de tela de 4–6 horas/dia (RP 1,23, IC95% 1,04–1,46) e ≥6 horas/dia (RP 1,50, IC95% 1,28–1,77); e estresse, com 4–6 horas/dia (RP 1,25, IC95% 1,08–1,44) e ≥6 horas/dia (RP 1,49, IC95% 1,30–1,71), também comparados com seus pares com ≤2 horas/dia. Conclusões: O tempo de tela foi associado positivamente com os sintomas de depressão, ansiedade e estresse em adolescentes. Atenção especial deve ser dada àqueles que passam mais de quatro horas por dia em frente a uma tela. Objetivo Métodos 98 1215 12 15 12-1 anos PR. PR .

ABSTRACT Objective: To examine the associations between self-reported screen time and symptoms of stress, anxiety, and depression in adolescents. Methods: A cross-sectional study was conducted with 982 adolescents aged between 12 and 15 years, enrolled in public schools in Jacarezinho (PR), Brazil. Screen time was assessed by the question “Considering a typical day, how much time do you spend watching TV, playing videogame, using computer or smartphone?” The DASS-21 questionnaire (short form) was used to assess symptoms of depression, anxiety, and stress. Crude and adjusted analyses (age, sex, and maternal level of education) between screen time and mental disorders symptoms were performed using general linear regression models, with Poisson distribution, with significance level at p<0.05. Results: Higher depressive symptoms were observed in adolescents who reported screen time of 4–6 hours/day (PR 1.35, 95%CI 1.13–1.61) and ≥6 hours/day (PR 1.88, 95%CI 1.62–2.19), compared with their pairs with <2 hours/day. The same was observed for anxiety symptoms with screen time of 4–6 hours/day (PR 1.23, 95%CI 1.04–1.46) and ≥6 hours/day (PR 1.50, 95%CI 1.28–1.77); and stress, with 4–6 hours/day (PR 1.25, 95%CI 1.08–1.44) and ≥6 hours/day (PR 1.49, 95%CI 1.30–1.71), also compared with their pairs with <2 hours/day. Conclusions: Screen time was positively associated with depressive, anxiety, and stress symptoms in adolescents. Special attention should be given to those who spend more than four hours a day in front of a screen.

RESUMO: O uso de métodos não destrutivos e de baixo custo para determinação de área foliar tem ganhado importantes aplicações. Os objetivos da pesquisa foram (i) propor um método não destrutivo para estimar a área foliar da cultura da mamona e (ii) construir equações que estimem com precisão e rapidez a área foliar da espécie. Foram coletadas mil folhas sadias e expandidas de cinco cultivares de mamona (New Zealand Purple, Sipeal, Carmencita, Amarelo de Irecê e IAC-80), sendo coletadas 200 folhas de cada uma. O comprimento máximo, largura máxima e área foliar foram calculados para cada folha. Foi calculado o produto entre comprimento e largura (LW). Foram realizados testes com diferentes modelos de regressão linear e não linear entre área foliar e dimensões lineares das folhas de cada cultivar. Os modelos utilizados foram linear, linear sem intercepto e potência. Os critérios para escolha dos melhores modelos para estimar a área foliar da mamona foram maior coeficiente de determinação, maior coeficiente de correlação linear de Pearson, menor critério de informação de Akaike, maior índice de concordância de Willmott e menor raiz do erro quadrático médio. As equações que apresentaram melhores critérios para estimativa da área foliar das cultivares de mamona foram aquelas que utilizaram o produto entre comprimento e largura, em comparação às equações que utilizaram apenas uma dimensão foliar. O modelo ŷ = 0,439 × LW pode ser utilizado para estimar com precisão e rapidez a área foliar da mamona por meio de medidas lineares das folhas, utilizando o produto entre comprimento e largura (LW), independente da cultivar escolhida.

ABSTRACT: Using non-destructive and low-cost methods to determine leaf area has gained important applications. The research objectives were (i) to propose a non-destructive method to estimate the leaf area of castor bean crops and (ii) to build equations that accurately and quickly estimate the leaf area of specie. One thousand healthy and expanded leaves of five castor bean cultivars (New Zealand Purple, Sipeal, Carmencita, Amarelo de Irecê, and IAC-80) were collected, and 200 leaves were collected from each. The maximum length, maximum width, and leaf area were calculated for each leaf. The product between length and width (LW) were calculated. We performed tests with different linear and non-linear regression models between leaf area and linear leaf dimensions of each cultivar. The models used were linear, linear without intercept, and power. The criteria for choosing the best models to estimate the leaf area of castor beans were a higher coefficient of determination, more elevated Pearson’s linear correlation coefficient, lower Akaike information criterion, higher Willmott agreement index, and smallest root mean square error. The equations that presented the best criteria for estimating the leaf area of castor bean cultivars were those that used the product between length and width, compared to equations that used only one leaf dimension. The model ŷ = 0.439 × LW can be used to accurately and quickly estimate the castor bean leaf area through linear measurements of the leaves, using the product between length and width (LW), regardless of the cultivar chosen.

RESUMO: Existem poucos estudos sobre a extração de compostos bioativos do bagaço de azeitona pelo método de micro-ondas de hidrodifusão e gravidade (MHG). Portanto, este estudo teve como objetivo extrair compostos bioativos do bagaço por MHG utilizando um composto rotacional central (DCCR). O modelo estatístico apresentou diferença significativa para a variável potência (W) nas extrações de compostos fenólicos, apresentando comportamento linear. A análise de regressão linear simples sugere a utilização de 100W de potência para a extração de compostos fenólicos em bagaço de azeitona. Não houve diferenças significativas nas extrações de flavonóides e na capacidade antioxidante dos extratos, em diferentes potências (W) e tempos (min), nos extratos de bagaço de azeitona.

ABSTRACT: There are few studies on the extraction of bioactive compounds from olive pomace by the microwave method of hydro diffusion and gravity (MHG). Therefore, this study extracted bioactive compounds from pomace by MHG using a central rotational compound (DCCR). The statistical model showed a significant difference for the variable potency (W) in the extractions of phenolic compounds, showing linear behavior. Simple linear regression analysis suggested the use of 100W of power for the extraction of phenolic compounds in olive pomace. There were no significant differences in flavonoid extractions and antioxidant capacity of the extracts, at different potencies (W) and times (min), in the olive pomace extracts. ABSTRACT MHG. .

ABSTRACT Introduction: the postgraduate educational climate (CE) in the hospital environment can determine the way in which resident physicians (MRs) adapt to their new stage, during which professional burnout syndrome (PAS) is highly likely to occur at some point. Objective: to determine the relationship between the educational climate and professional burnout in physicians in the medical residency programs of the National Hospital 2023-2024. Methodology: cross-sectional observational study of a sample of MR convenience of both sexes from all medical specialties of the National Hospital between November 2023 and January 2024, MR with external rotation and/or vacations were excluded. Sample calculation; 136 MR. An online form from Google was sent to the MR email requesting voluntary participation. The SAP was measured with the standard Maslach Burnout Inventory (MBI) method with subscales; emotional exhaustion (EA), depersonalization (DESP), personal fulfillment (PR), with PAS with high scores of AE, DESP and low RP. The EC was assessed with the measure of the hospital postgraduate educational environment (PHEEM) with subscales; perception of role autonomy (PAR), perception of teaching (PE), perception of social support (PSS), the higher the score, the better the EC. Demographic and academic variables, MBI and PHEEM scores were collected, and the SAP was considered dependent, as the main result was the predictive relationship of the PHEEM on the SAP. Data were compared with χ², t-test or Mann-Whitney U, ANOVA and linear regression (p-significant value =<0.05). Results: of 233 participants, the mean age was 28.75 (±2.20), 63.94 % (149) women, the general prevalence of PAS; 70.38 % (164/233), PAS in men 75 % (63/84) and women 67.78 % (101/149) p=0.0014, the first 2 years with the highest frequency of PAS; 65 (85.52 %), 59 (86.76 %) respectively p=0.0009, 63 (90 %) p=0.0071 surgical specialties.

Abstract This work aims to model per capita water consumption in schools in the city of Joinville-SC. As the school environment is largely responsible for the transmission of knowledge, including information on water conservation, 26 public schools were selected for this research. A survey was carried out on the use of water, through visits and a questionnaire to the management team of each school. The data collected allowed the characterization of schools and a preliminary diagnosis of water use. A descriptive analysis of per capita water consumption was performed, with values ranging from 5.15 to 18.59 liters/student/day. Correlation analysis, multiple linear regression, Bayesian linear regression and geographically weighted regression were used. The results of the correlation analysis reveal that the higher the average income in the neighborhood where the school is located and the area per student ratio, the higher the per capita water consumption. On the other hand, the number of students has a negative correlation with per capita consumption. In the statistical modeling, the independent variable area per student ratio was significant.

Abstract Colostrum is the first mammary secretion and in which calves can obtain passive immunity. This study aimed to correlate the quality of colostrum from high-yielding dairy cows using either a colostrometer or Brix digital refractometry (°Bx). Samples (N=340) of colostrum were taken from cows and analyzed with a colostrometer and Brix refractometry. A linear regression was performed. The coefficient of determination (R2) was calculated. All statistical analyzes were done with the SPSS 25.0 statistical package. Means with colostrometer were 87.94±110, while with Brix refractometer they were 26.19±18, with R2 0.706 and a P<0.0001. In conclusion, the refractometer and the colostrometer are effective methods to determine immunoglobulins. Brix refractometer had an acceptable correlation, which could be a useful tool for verifying the colostrum’s quality next to the cow.

ABSTRACT Introduction: Although nerves and vessels of the penis play important role in erection, there are few studies on their development in human fetus. Therefore, the objective of the present study is to analyze, quantitatively, in the corpora cavernosa and corpus spongiosum, the development of the nerves and vessels in the fetal penis at different gestational ages. Material and Methods: Fifty-six fresh, macroscopically normal human fetuses aged from 13 to 36 weeks post-conception (WPC) were used. Gestational age was determined by the foot length criterion. Penises were immediately fixed in 10% formalin, and routinely processed for paraffin embedding, after which tissue sections from the mid-shaft were obtained. We used immunohistochemical staining to analyze the nerves and vessels in the corpus cavernous and in the corpus spongiosum. These elements were identified and quantified as percentage by using the Image-J software. Results: The quantitative analysis showed that the percentage of nerves varied from 3.03% to 20.35% in the corpora cavernosa and from 1.89% to 23.88% in the corpus spongiosum. The linear regression analysis indicated that nerves growth (incidence) in the corpora cavernosa and corpus spongiosum correlated significantly and positively with fetal age (r2=0.9421, p<0.0001) and (r2=0.9312, p<0.0001), respectively, during the whole fetal period studied. Also, the quantitative analysis showed that the percentage of vessels varies from 2.96% to 12.86% in the corpora cavernosa and from 3.62% to 14.85% in the corpus spongiosum. The linear regression analysis indicated that vessels growth (appearance) in the corpora cavernosa and corpus spongiosum correlated significantly and positively with fetal age (r2=0.8722, p<0.0001) and (r2=0.8218, p<0.0001), respectively, during the whole fetal period studied. In addition, the linear regression analysis demonstrated a more intense growth rate of nerves in the corpus spongiosum during the 2nd trimester of gestation, when compared with nerves in the corpora cavernosa. In addition, the linear regression analysis demonstrated a more intense growth rate of vessels in the corpus spongiosum when compared with the corpora cavernosa, during the whole fetal period studied. Conclusions: In the fetal period, the human penis undergoes major developmental changes, notably in the content and distribution of nerves and vessels. We found strong correlation between nerves and vessels growth (amount) with fetal age, both in the corpora cavernosa and corpus spongiosum. There is significant greater proportional number of nerves than vessels during the whole fetal period studied. Also, nerves and vessels grow in a more intense rate than that of the corpora cavernosa and corpus spongiosum areas.

Abstract Introduction. The cultivation of dragon fruit (Hylocereus costaricensis and H. monocanthus) is increasing in Costa Rica, but technical information for its management, such as nutritional requirements, fertilization timing, and growth behavior, is lacking. Objective. To quantify and model the growth and nutrient uptake of dragon fruit (H. costaricensis and H. monocanthus) under dry tropics conditions in Costa Rica. Materials and methods. The research was conducted from 2017 to 2020 in Guanacaste, Costa Rica. Plants were sampled at 76, 165, 308, 450, 607, 903, 1249, and 1706 days after planting (DAP) and 205 fruits were analyzed. Dry matter was quantified, and the uptake of N, P, Ca, Mg, K, S, Fe, Cu, Zn, Mn, and B was calculated. Two logistic models were fitted to determine nutrient uptake, and linear regressions were calibrated for fresh fruit. Results. For a planting density of 3000 plants/ha, the nutritional requirements per hectare were: 137 kg N, 32 kg P, 327 kg K, 63 kg Mg, 32 kg S, 1,60 kg Zn, and 0,21 kg B. The best-fitting logistic model (RMSE = 0.09) accurately estimated the uptake of N, P, Ca, S, Zn, and B. The linear regression model demonstrated high predictive capacity (R2 > 0.85) for the nutrient requirements of N, P, K, Mg, and S in the fruit. Conclusion. Logistic models provided high precision in deterministically modeling nutrient uptake in dragon fruit plants. The study affectively quantified and modeled the nutritional behavior of the plants under Costa Rica’s dry tropical conditions, providing essential information for optimizing fertilization programs for the crop.

ABSTRACT One of the consequences of climate change is sea level change in coastal systems, which function as a baseline, where a variety of coastal processes operate at different time and space scales. The objective of the present research is to calculate the historic and current rate of sea level rise, from Limon tide gauge station’s data. Two methods were utilized for this purpose: Simple linear regression analysis and time series decomposition; with the first method, a rate of 2.32 mm/yr of sea level change was obtained for the time period 1952 to 1968; with the second one, a rate result of 3.41 mm/yr which is consequent with the existing publications. In the current period (2009 - 2021) a rate of 4.18 mm/yr was obtained with the first method and 4.28 mm/yr with the second method. The results gathered confirm the existence of an upward trend in sea level rise in the studied region. This situation should be considered when studying the transformation taking place in the coast, such as the coastal erosion identified in some of the Costa Rican Caribbean zone.

RESUMEN Entre las consecuencias del cambio climático en los sistemas costeros está el cambio del nivel del mar, el cual funciona como una línea base sobre la cual opera una variedad de procesos costeros, a diferentes escalas de tiempo y espacio. La presente investigación tiene por objetivo calcular la tasa histórica y actual de ascenso del nivel del mar a partir de datos de la estación mareográfica Limón. Para esto se utilizaron dos métodos: el análisis de regresión lineal simple y una descomposición de series temporales. Como resultado se obtuvo una tasa de cambio del nivel del mar para el período 1952 a 1968 de 2.32 mm/año con el primer método y 3.41 mm/año para el segundo método, que es consecuente con las publicaciones existentes. En el caso del período actual (2009 a 2021) se obtuvo una tasa de 4.18 mm/año para el primer método y 4.28 mm/año con el segundo método. Los resultados obtenidos confirman que existe una tendencia al aumento del nivel del mar en la región estudiada, situación que debe ser considerada al estudiar las transformaciones que están ocurriendo en la costa, como lo son la erosión costera identificada en algunas zonas del Caribe costarricense.

Abstract: This study investigated the effects of perceived parental bonding, sociodemographic and gestational variables on the intensity of maternal-fetal attachment (MFA) in the context of high-risk pregnancies. This is a quantitative, cross-sectional study involving 119 participants. A sociodemographic questionnaire, the Maternal-Fetal Attachment Scale-Brief Version, and the Parental Bonding Instrument were administered. The results of the multiple linear regression analysis were statistically significant (p < .05). The final model explained 28.7 % of the variance in MFA and included the variables of paternal overprotection, paternal care, maternal age, gestational age, and the support from the baby's father. We emphasize that MFA intensity is multidetermined, involving aspects of life history, social, and situational factors. The woman’s perception of paternal bonding during her childhood and adolescence, as well as the support from the baby's father during the gestational period, are highlighted as influential factors for maternal-fetal attachment, indicating the importance of paternal involvement throughout the life cycle. Implications for professional practice, as well as limitations and recommendations for future studies are discussed.

Summary: The fraction of vegetation cover (FVC) and the Leaf Area Index (LAI) are biophysical variables closely related to the evapotranspiration rate of crops and their biomass production. Despite their importance, they are usually not measured directly due to their time-consuming and costly nature; however, they can be estimated on a large scale and near-real-time using spectral information captured in satellite images, although this requires prior validation at the field level. Simple linear regression models were developed and validated using 13 vegetation indices (VI) related to LAI and FCV in alfalfa (Medicago sativa). Three spectral information sources were used: (i) reflectance to derive the VI; (ii) digital photographs processed with the Canopeo application to estimate FVC; and (iii) direct LAI measurements using a ceptometer. Six field samples were taken between March and June, 2020 in four alfalfa plots located in Palmar de Bravo, Puebla, Mexico. To evaluate each VI, the determination coefficient (R2) and the root mean square error (RMSE) were used. We found that the most suitable VI for estimating FVC was the VIgreen (Green Vegetation Index, R2 =0.987 and RMSE = 0.093). For the LAI, the VI that performed best was the NDVI (Normalized Difference Vegetation Index, R2 = 0.935 and RMSE = 0.746). The results showed the suitability and practical utility of spectral information for estimating biophysical variables in alfalfa cultivation and their monitoring.

Resumen: La fracción de cobertura vegetal (FCV) y el índice de área foliar (IAF) son variables biofísicas relacionadas estrechamente con la tasa de evapotranspiración de los cultivos y su producción de biomasa. A pesar de su importancia, usualmente no se miden de manera directa debido al tiempo invertido y costo; sin embargo, se pueden estimar a gran escala y en tiempo casi real mediante información espectral captada en imágenes de satélite, pero esto requiere de su validación a nivel de campo. Se desarrollaron y validaron modelos de regresión lineal simple utilizando 13 índices de vegetación (IV) relacionados con el IAF y la FCV en alfalfa (Medicago sativa). Se usaron tres fuentes de información espectral: (i) La reflectancia para derivar los IV; (ii) fotografías digitales procesadas con Canopeo para estimar la FCV; y (iii) mediciones del IAF utilizando un ceptómetro. Se realizaron seis muestreos de campo entre marzo y junio de 2020, en cuatro parcelas de alfalfa situadas en Palmar de Bravo, Puebla, México. Para evaluar cada IV, se utilizó el coeficiente de determinación (R2) y la raíz del cuadrado medio del error (RCME). Se encontró que el IV más apropiado para estimar la FCV fue el VIgreen (Green Vegetation Index, R2 = 0.987 y RCME = 0.093). En el caso del IAF, el IV que presentó el mejor desempeño fue el Normalized Difference Vegetation Index (NDVI), R2 = 0.935 y RCME = 0.746). Los resultados mostraron la aptitud y utilidad práctica de la información espectral para estimar las variables biofísicas en el cultivo de alfalfa y su monitoreo.

Resumen El desarrollo de proyectos mineros en etapas de exploración y prefactibilidad conlleva desafíos relacionados a la heterogeneidad e incertidumbre geológica y de procesamiento debido a la variabilidad en sus atributos primarios y de respuesta. Por lo tanto, el objetivo de esta investigación radica en elaborar el modelo geometalúrgico del índice de trabajo de Bond. Para esto se desarrollaron modelos de regresión lineal en Jupyter Notebook considerando 790 muestras de resistencia a la compresión uniaxial de la roca (UCS), litologías, zonas minerales e índice de trabajo de Bond (BWi) en un depósito pórfido cuprífero. Los resultados indican relación directamente proporcional de tipo lineal entre el BWi y UCS, generando modelamientos con desempeños aceptables de R2 entre 0,76 a 0,90. Además, las litologías y zonas mineralizadas en el depósito estudiado son características relevantes relacionadas a la conminución. Finalmente, de acuerdo a la competencia de la roca, esta se clasifica como tipo media a dura, dura y muy dura en las zonas de óxidos, mixtos y sulfuros primarios respectivamente.

Abstract The development of mining projects in the exploration and pre-feasibility stages involves challenges related to geological and processing heterogeneity and uncertainty due to variability in their primary and response attributes. Therefore, the objective of this research is to develop the geometallurgical model of the Bond work index. For this purpose, linear regression models were developed in Jupyter Notebook considering 790 samples of uniaxial compressive strength of rock (UCS), lithologies, mineral zones and Bond work index (BWi) in a porphyry copper deposit. The results indicate a directly proportional linear relationship between BWi and UCS, generating modeling with acceptable R2 performances between 0,76 and 0,90. In addition, the lithologies and ore zones in the deposit studied are relevant characteristics related to comminution. Finally, according to rock competence, the rock is classified as medium to hard, hard and very hard in the oxide, mixed and primary sulfide zones, respectively.
