The present study aimed to study the morphological variability of indigenous chicken in the south of Ecuador. A total of 200 adult individuals (31 males and 169 females) were characterized with the support of 14 descriptors for morphometric characterization established by FAO. On these measurements, body weight and length of the tarsus were selected due to their direct relationship with the productive characteristics of interest to the study. Ten biotypes of indigenous chicken were identified having evident physical differences among them. By using a multivariate statistical analysis, the biotypes were grouped in three clusters for females and in two clusters for males.

The article explores the use of convolutional neural networks, specifically ResNet-50, to detect weevils in corn kernels. Weevils are a major pest of stored maize and can cause significant yield and quality losses. The study found that the ResNet-50 model was able to distinguish with high precision between weevil-infested corn kernels and healthy kernels, achieving values of 0.9464 for precision, 0.9310 for sensitivity, 0.9630 for specificity, 0.9469 for quality index, 0.9470 for the area under the curve (AUC) and 0.9474 for the F-score. The model was able to recognize nine out of ten weevil-free corn kernels using a minimal number of training samples. These results demonstrate the efficiency of the model in the accurate detection of weevil infestation in maize grains. The model's ability to accurately identify weevil-affected grains is critical to taking rapid action to control th...

The aim of this article is to report an atypical case of Heck's disease, given its single-site positivity for HPV genotypes 56, 71 and 74, with different biological significance. This disease is a benign oral pathology with variable prevalence according to geographic region and ethnic group; its etiology is multifactorial, in which the human papillomavirus (HPV), genotypes 13 and 32 play a leading role. However, in the last ten years, sporadic cases of this pathology have been documented, positive for non-classical genotypes and high oncogenic risk. The clinical and histopathological picture found in the patient's oral cavity was consistent with the entity in reference, confirmed by a molecular study based on polymerase chain reaction for HPV genotypes 56, 71 and 74. In conclusion, the present case is considered unusual due to positivity for genotypes that have not been documented in thi...

This exploratory study analyzed ten factors related to motivation towards job satisfaction, as proposed by Herzberg, Mausner, and Snyderman (1959), and their influence on faculty performance in a representative sample of faculty members of the Pontifical Catholic University of Ecuador between 2010 and 2011. These factors included work characteristics (internal factors) as well as context characteristics where work is performed (external factors). The effect that some faculty members' characteristics, such as faculty time category (i.e. full-time, half-time, part-time), position category, and gender had on job satisfaction and on the motivational factors was also analyzed. Statistical analysis showed that the external factor “job supervision” was a significant predictor of faculty performance. Statistically significant differences were found in some specific motivational factors, depe...
