Career anchors are defined by the competence, motivation, and values a person has to perform a particular job in an organization and are present throughout their working life. When determining the soft and hard competencies of the professional profile, universities must consider the career anchors essential for graduates’ work performance. To determine which anchors dominate the competencies of the graduate profile, two universities in Latin America with a degree in accounting were selected. The study was organized in two stages: first, the operationalization of the research was conducted, including the description of the instrument through the application of 40 questions divided into Schein’s eight anchors. Samples were selected based on the convenience of the...

El objetivo de la investigación fue evaluar la cinética de degradación térmica de la vitamina C de la pulpa de tumbo (Passiflora mollissima b.). Se preparó la pulpa de tumbo que posteriormente fue sometida a diferentes temperaturas (60, 70 y 80°C) y tiempos (0, 5, 10, 15 y 20 min). El contenido de vitamina C en la pulpa de tumbo fue de 77.01 mg/100g que se analizó por espectrofotometría. Los resultados mostraron que la degradación de la vitamina C siguió los modelos cinéticos de segundo orden. Las constantes de velocidades de degradación para el ácido ascórbico en la pulpa de tumbo fueron: k60 = 0,014 min-1, k70= 0,019 min-1 y k80 = 0,023 min-1 y los tiempos de reducción decimal son: D60=162.17 min, D70 = 121.74 min y D80 =101....

The Gompertz and Logistico equations were applied in four treatments. The first was a mixture in 250 ml flasks between distilled water - Chaska (T1); the second distilled water - Black (T2); the third Salina Peptonada Solution - Chaska (T3); and the last Peptonada Saline Solution - Black (T4). These treatments were sterilized at 121 ° C for 15 min, then SB was inoculated at 37 ° C with constant agitation of 20 RPM for a lapse of 7 hours; where, at intervals of one hour, the readings of the biomass increase were made with a microcosp and a neubauer chamber expressed in colony forming units per milliliter (cfu / ml); Likewise, a comparison of the pH, oBrix and acidity between the tunta varieties was made in fermentation times of 24 and 48 hours. The results of the mathematical modeling showed that graphically the T1 a...

For this purpose, flasks were prepared with 200 mL of fresh cow's milk, previously sterilized at 121 ° C x 15 min, then the strains were inoculated at a temperature of 37 ° C and incubated at the same temperature under constant shaking of 20 revolutions per minute (rpm) in a water bath with shaking, for 7 h; To construct the curves and obtain the growth constants, colony-forming units were counted per milliliter (cfu / ml) at one-hour intervals, with a monocular microscope and Neubauer chamber. Also, the pH and titratable acidity expressed in lactic acid were measured. The data obtained were converted to a logarithmic scale to...

Se empleó la metodología de molienda húmeda para obtener el Extracto Vegetal de Tarwi (EVQ), luego se procedió a formular las mezclas con sacarosa (6 y 12 %) e inóculo de Saccharomyces boulardii (2 y 4 %) y se obtuvo así cuatro tratamientos (A1 – A4) con réplicas; la inoculación fue realizada a 37 °C con agitación constante a 20 RPM durante 24 horas. Se realizaron las lecturas del incremento de biomasa con un microscopio y una cámara de neubauer, expresado en (ufc/ml) en intervalos de 3 horas; se construyó curvas y parámetros cinéticos de crecimiento microbiano con el modelo matemático de Gompertz; se realizó un monitoreo de °Brix, densidad, pH, y % de acidez; se aplicó un análisis de regresión lineal; finalmente se realizó el ajuste del modelado matemático. Los resultados de la cinética de crecimiento microbiano ...
