According to many researchers Wendell C. Bennett was the most important archaeologist of his time abroad. His profuse work led to it being considered as one of the founders of the Bolivian archaeological research. However, their contribution has been little considered in Peru, despite its many excavations in the valleys of Lambayeque and La Libertad; as well as iconic sites like Chavin and Huari. This rich information escapes our article, which will focus only on highlighting its work in the Lake Titicaca, considering excavated in key places like Tiwanaku and Chiripa, the first systematized information for this region. It is proposed that their approaches are still in place, often covertly in the interpretations of archaeologists interested in the highland region. Even their formulations achieved pan-Andean trim with its proposed ceremonial centers and Co-Tradition.

Cervical cancer is currently the fourth most frequent type of cancer in women. A large number of techniques from the Artificial Intelligence (AI) such as Neuronal Networks, Support Vector Machines (SVM), Decision Trees and others; have been used to deal with the problem of predicting this disease. The following paper shows the cervical cancer risk prediction, by implementing a probabilistic model based on Bayesian Networks and using 322 instances where we could retrieve 15 different features that are known information from each patient. The tests were made using the 40% of the whole dataset, confusion matrix and AUC indicator. The results show that this work has raised a 96% of success rate as well as 0.9864 in terms of the AUC indicator, in addition to this, the results suggest that Bayesian Networks are able to reach a high performance and provide transparency during the inference proc...

Resumen.

Red pitahaya (Hylocereus guatemalensis) peel is a by-product of pulp and juice production, which is often underutilized due to the lack of scientific information on how to preserve it in a manner that minimally affects its bioactive compounds. The objective of this study was to evaluate the effect of hot air drying on the total phenolic content (TFC) and antioxidant capacity (AC) by DPPH radical scavenging (%) of red pitahaya peel. The peel was separated from the pulp, cut into four equal parts and subjected to hot air drying. Drying was carried out at temperatures of 40, 50, 60, 60, 70, 80 and 90 °C for a period of 1 080 min. The peel was ground (particles < 850 μm), the extract (50 mg/mL) was obtained using 80% methanol as solvent, and the TPC and AC were determined. The influence of drying temperature was significant (p<0.05) on TPC and AC as drying temperature increase of 40 ...
