We analyse photometric data of nine supernovae (SNe) in filters V , R and I obtained during observational campaigns at the OAUNI site in 2016, 2017 and 2023. The calibrated magnitudes of the observed SNe were compared with their respective light curves available in the literature to study their evolution after their maximum brightness. In some cases, the supernova color-color diagnostic diagram was used to determine our observation date and correctly locate our magnitudes on the light curves. For this purpose, the use of supernova light curve templates, as well as reference supernovae, was also helpful. This work allowed us to verify the feasibility of performing precision astronomical photometry at the OAUNI.

Serum adenosine deaminase enzyme determinations were perfonned in 74 adult individuals of both sexes, consisting of 29 adult patients with active pulmonary tuberculosis, and 45 voluntary healthy individuals with no recent or past tuberculosis history, who constituted thecontrol group. The mean value of ADA enzyme serum activity in the group of patients with pulmonary tuberculosis was 47,89 + 6,05 U/L, and in the group of healthy individuals, 18.84 + 6.16 U/L. The difference between the means of serum ADA enzyme activity in the tuberculosis patients and the mean value of the control group was statistically significant (p < 0,001). The validation criteria showed the following results: sensitivity, 100%; specificity, 91.11%; efficiency, 94.59%; predictive value of positivity, 87,88%; predictive value of negativity, 100% .In the cases with high prevalence value, serum ADA test can be a si...

Objective. To evaluate the effects of endosperm of tara seeds (ETS) and powder of Agave americana leaves (AAL) on body weight and intestinal transit time in Holtzman rats. Materials and Methods. Twenty-five male Holtzman rats, individually caged, and distributed into five groups were fed for 21 days with one of the following treatments: T1, diet with 6% alpha cellulose (Control); T2, diet with 6% ETS; T3, diet with 6% AAL; T4, diet with 10% ETS; and T5, Diet with 10% AAL. Feed intake, body weight gain, apparent digestibility of fat, characteristics of feces (fat content, weight, moisture, volume, and pH) and intestinal transit time were recorded. One-way analyses of variance (ANOVA) were performed, as well as Tukey’s multiple means comparison. Results. Diets with 6% and 10% of ETS resulted in a reduction of feed intake, apparent digestibility of fat, and fecal pH, and said results had ...

This experimental work hopes to provide a potential solution by proposing techniques to improve the axial resistance capacity of reinforced concrete walls, using high-strength carbon filaments, and proposing a practical methodology for reinforcing existing reinforced concrete columns and walls. The methodology used to improve this work consists of the exploration and experimentation of two explicit parts, the first being a progression of material tests carried out in the laboratories of the Pontificia Universidad Católica del Perú, with the purpose of determining the direct mechanical properties. and not direct. The second part of the work included the analysis of the reinforced concrete walls through the non-linear concept modeled with the finite element method, verifying the non-linear attributes of the concrete by increasing the high-resistance carbon fiber. The results found have b...
