El presente aporte se circunscribe a uno de los más serios problemas de la criminalística peruana, el abandono de la poroscopia, disciplina abocada al estudio de los poros presentes en la piel. Para ello, se efectuó el estudio de la literatura nacional e internacional que versa sobre la dimensión teórica de esta rama del saber y la evidencia empírica referida a su aplicación. Se concluyó que, el uso de la poroscopia optimizaría la identificación personal, al reducir varios de los equívocos provocados por el empleo aislado de los dos primeros niveles de análisis dactilar, e incrementaría la fiabilidad de las homologaciones, motivos por los que la misma debe ser implementada a nivel nacional.

VINASSE IS ACIDIC, DARK BROWN WASTEWATER OBTAINED AS A RESIDUE FROM THE ALCOHOL DISTILLATION PROCESS, THE MAIN COMPONENT OF WHICH IS WATER, IN ADDITION TO MINERAL NUTRIENTS AND A HIGH ORGANIC LOAD. ELECTROCOAGULATION (EC) IS A TECHNOLOGY THAT GENERATES COAGULATING SUBSTANCES IN SITU BY OXIDIZING SACRIFICIAL ANODES THROUGH AN ELECTRIC CURRENT APPLIED TO THE ELECTRODES. DURING THE LAST DECADE, THE ELECTROCOAGULATION PROCESS HAS BEEN INTENSIVELY INVESTIGATED IN SEVERAL REVIEWS, DUE TO ITS EASE OF OPERATION, VERSATILITY, SUSTAINABILITY AND LOW ENVIRONMENTAL IMPACT. THE OBJECTIVE OF THE PRESENT WORK HAS BEEN TO MAKE A GENERAL REVIEW OF THE EC PROCESS, ITS PRINCIPLE, REACTION MECHANISM AND OPERATING PARAMETERS INVOLVED IN THE ELECTROCOAGULATION PROCESS. IN THIS RESEARCH, THE PRISMA METHOD WAS USED FOR THE ANALYSIS OF ARTICLES FROM DIFFERENT DATABASES SUCH AS SCOPUS, SCIENCEDIRECT AND GOOGLE SC...

Twenty seven homing pigeons (10 males and 17 females) were biometrically studied and the bilateral symmetry (right-left) level was evaluated. Analysed traits were the length of outer external rectrices, length of the wing and length of the second primary feather. The aim of the study was to check whether there is a relationship between the degree of asymmetry level and general health of the birds (expressed as a measure of body condition). Measurements showed a normal distribution and without differences according to the body condition, indicating a high degree of stable growth.

Objective. Understand the perspective of patients in relation to the current way of obtaining an appointment in primary health care. Methods. A bibliography search was performed in the online databases in Spanish and English. The main source was sought by reviewing the bibliographical references of the publications. Results. It was found that the shift to virtuality has made it easier for users to access a primary health care appointment, reducing waiting time and paving the way for non-face-to-face care; the level of user satisfaction has increased positively. Conclusions. Phone and virtual requests are here to stay; these are not intended to replace face-to-face requests, but they are a necessary tool to improve the quality of care for users.

This paper is based on the premise that parole assumes the configuration of rights and the objective was to reach an approximation to the implications of such a postulate in the Peruvian legal system. For that purpose, an analysis of the national and international literature that deals with the dogmatic and applicational dimensions of these figures was carried out. It was concluded that it is not possible to restrict the legal application of early release, regardless of the seriousness of the crime or sentence imposed, and that the concession factors to be legislated must be based on empirical evidence related to recidivism.

The present research aimed to examine whether perfectionism and some demographic variables can predict levels of resilience (and their dimensions) in adults from Venezuela. The design was cross-sectional predictive, through logistic regression analysis. Participants were 313 Venezuelan mature adults (M = 46.44 years), mostly women (82.7%), residents of the interior of the country (70.9%), with higher education (64.2%), and paid employment (67.9%). An adapted version of the Multidimensional Perfectionism Scale (Frost et al., 1990) and the Resilience Scale for Adults (Hernández y Lezama, 2016) was applied via Google Forms. Organization was a positive predictor of resilience and two of its dimensions (OR = 1.13 - 1.27), while fear of mistakes was a negative predictor of resilience and “morality and values” (OR = 0.96). Personal standards positively predicted“perseverance and hope” ...

Cancer is the second leading cause of death in Latin America, and the economic cost it requires will increase markedly in future years (1). If nothing is done about it, cancer incidence and mortality in South and Central America will continue to rise sharply between 2012 and 2035 (2). It is expected that by 2030 the incidence of cancer will increase by 32%, reaching 5 million cases per year (1). At the level of Latin America, health policies have been implemented, where they prioritize the feeding of these patients to reduce the sequelae that the treatments can cause, obtaining optimal results (3). It is in this context that the effects of cancer and its treatment make it difficult to meet the nutritional requirements of patients. Chemotherapy is the most widely used medical treatment for cancer in the world. Knowing that cancer cells tend to grow and divide faster than normal cells, thi...

La reciente identificación de las subunidades nicotínicas a9 y a10 en células sensoriales del aparato auditivo y en neuronas de los ganglios raquídeos, motivaron a investigar la posible expresión de estas subunidades en el parénquima adrenomedular. Mediante la técnica electrofisiológica de “patch-clamp”, se ha medido las corrientes mediadas por los receptores nicotínicos de la acetilcolina en células cromafines de rata (nAChRs). Dos agonistas nicotínicos, la acetilcolina (ACh) y nicotina (Nic) activaron corrientes con una concentración eficaz 50 (CE50) de 63 y 24μM, respectivamente. La colina, agonista selectivo de receptores nicotínicos a7 y a9a10, y la oxotremorina-M, agonista del receptor a9a10, indujeron respuestas con eficacias del 13% y 27%, respectivamente, con respecto a la obtenida con ACh (100μM). La bungarotoxina (BgTx) bloqueó parcial y reversiblemente (CI...

El presente estudio analiza la variación de los parámetros de resistencia de suelos lacustres en Cerro de Pasco ante el incremento de sobrecarga inducido por la construcción progresiva de diques. Para su evaluación se emplearon resultados de ensayos de penetración estándar (SPT) realizados en diferentes años (2010, 2019 y 2025), correspondientes a etapas sin carga y posteriores a la aplicación de cargas de 540 kPa y 620 kPa. Los valores del número de golpes fueron corregidos mediante la metodología (N₁)₆₀ según la norma ASTM D1586, y se determinaron los parámetros geotécnicos derivados: cohesión no drenada (Cu), ángulo de fricción interna (φ), coeficiente de presiones laterales en reposo (K₀), módulo de deformación (Es) y presión admisible (qadm). Los resultados evidencian una reducción progresiva de Cu, Es y qadm a lo largo del tiempo, indicando que la sobre...

The use of manual methods to forecast demand in perishable food companies is generally subject to the variability of internal and external factors in the company, causing excess inventories and significant monetary losses, so it is relevant to carry out this research with the objective of to demonstrate that by implementing Machine Learning it is possible to improve the accuracy of the demand forecast. A case study in a company in the poultry sector in Peru, forecasting the last quarter of 2022, based on a real sales database and applying the time series method, comparing the results of the Machine Learning model, and obtaining as a result in a model with high Forecast Accuracy (FA) of 97.56% and a high Forecast Bias (FB) of 2.44%. The research is an important contribution to knowledge, demonstrating that Machine Learning is an ideal tool to project the demand for perishable food product...

Most Andean lakes and lagoons are used as reservoirs to manage hydropower generation and cropland irrigation, which, in turn, alters river flow patterns through processes of storage and discharge. The Carhuacocha and Vichecocha lagoons, fed by glaciers, are important aquatic ecosystems regulated by dams. These dams increase the flow of the Mantaro River during the dry season, supporting both energy production and irrigation for croplands. Water quality in the Carhuacocha and Vichecocha lagoons was assessed between storage and discharge events by using the Canadian Council of Ministers of the Environment Water Quality Index (CCME WQI) and multivariate statistical methods. The quality of both lagoons is excellent during the storage period; however, it decreases when they are discharged during the dry season. The most sensitive parameters are pH, dissolved oxygen (DO), and biochemical oxyge...
