The growth of Tetraselmis suecica was evaluated. The experiment was realized using the Response Surface Methodology (RSM) with Central Composite Rotational Design (CCRD) with two factors, pH and sanguaza/seawater concentration in the range of 7 - 9 and 2 - 5 % (v/v), respectively. The culture media were stirred by bubbling air constantly (0.07 L/s) and continuously illuminated with 40 W of fluorescent light in glass containers of 1.5 L capacity at a temperature of 22.5 ± 2.1 °C. Using the Gompertz mathematical model was determined that from an 8.0 of pH and a ratio of 3.5% of sanguaza/seawater, the Tetraselmis suecica achieves maximum growth. An 8.71 of pH and a ratio of 4.56% of sanguaza/seawater allow the Tetraselmis suecica maximum growth (logN/N0) of 0.659, with a 12.3% of prediction error by applying a mathematical model of 2nd order. According to the study, the values obtained in...

Objective: To describe the clinical–epidemiological characteristics and the survival time of deceased COVID-19 patients treated at hospitals belonging to Red Sabogal–Callao in 2020. Materials and methods: An observational, descriptive and retrospective study conducted in a population of 23 patients who died of COVID-19 from the beginning of the state of emergency (March 11, 2020) to April 15 at two hospitals belonging to Red Sabogal–Callao. The data was analyzed using the Stata Statistical Software: Release 16. The survival time was assessed by means of the Kaplan-Meier survival analysis and the log-rank test, with a 95 % confidence interval. Results: The predominant epidemiological characteristics were male sex, 60 to 79 years of age and comorbidities (hypertension and obesity). The main signs and symptoms at hospital admission were dyspnea, fever, cough and increased respiratory ...

Objective: To estimate the coverage of being a beneficiary of the Vaso de Leche (VDL – Glass of Milk) and Qali Warma (QW – Vigorous Child) programs among children under 5 years of age and to determine the associated factors. Materials and methods: This study used a secondary source, based on the 2022 Encuesta Demogrática y de Salud Familiar (Endes – National Demographic and Family Health Survey) in Peru. For this purpose, women aged 15 to 49 years with children aged five years or younger and complete anthropometric data were selected to answer questions about being a beneficiary of the VDL and QW programs. The dependent variable was being or not a beneficiary of the programs, and the rate of beneficiaries was compared across levels of the independent variables. A log-binomial regression from the family of generalized linear models was used for the multivariate analysis, with a sig...

La tesis reporta la caracterización magnética y estudio de la textura en capas superconductoras de YBa2Cu3O7-δ sobre el sustrato MgO. Se divide en dos partes. En la primera se reporta la caracterización tanto estructural, morfológica y magnética y la segunda parte consta de un estudio de la dinámica de vórtices de un filme superconductor del compuesto de YBa2Cu3O7-δ (YBCO), el cual ha sido crecido sobre el sustrato monocristalino de MgO (100) tipo-E, la cual fue donada por la empresa Ceraco. Para la primera caracterización estructural se emplea la Difracción de rayos-X (DRX), donde se observa picos del tipo (00l) pertenecientes al YBCO con crecimiento orientado. Fases secundarias, como el Y2BaCuO5 (Y211) y óxido de Cobre (CuO) también son detectados. El crecimiento ordenado, mostrado mediante DRX, es confirmado con micrografías de sección transversal, usando Microscopía e...
