Two commercial varieties of Peruvian Pouteria lucuma fruits namely “Seda” and “Beltrán” were characterized in terms of their physicochemical properties as well as their primary and secondary metabolites content and profile. Free sugars, dietary fiber, and starch comprise the main components in both varieties. Phenolic compounds derived from flavanoids (flavan-3-ols), gallic acid, and their derivatives were identified. Xanthophylls were tentatively identified based on their UV-vis spectra and enclosed the majority of the carotenoids found in lucuma. Additionally, both varieties showed to be sources of lipophilic compounds such as tocopherols (?, ?, and ?) and triterpenoids. The triterpenoid ?-amyrin was identified in a Pouteria fruit for the first time. The in vitro antioxidant capacity (AoxC) of the lipophilic fraction represented approximately 30% of the total AoxC. These resul...

The present report reports to the scientific community the product of the elaboration of the test of abilities for the management in the negotiation of conflicts, whose objective is to determine the abilities to manage the management of conflicts successful; part that this is the result of the complex interaction of five abilities: communication, commitment, perspective, emotional control, and empathy; on the basis of these supposed factors the test was constructed, the one that was put to consideration of judges and statistic analyses of the behavior of its components within the whole, having found that the test measures what it sets out from the point of view of the judges and who the factors are parts that they significantly relate to the whole, his you see to know the error measurement was used the method of the test retest and the method of the internal consistency of Cronbach, by b...

The objective of this work was to identify primary and secondary metabolites, volatile compounds, bioactive properties and physicochemical characteristics of lucuma fruit at two ripeness stages, before physiological maturity (bPM) and at physiological maturity (PM) or commercial harvest. The content of reducing sugars decreased, while starch content increased. Myo-inositol and vitamin C content decreased and increased, respectively as maturity stage advanced. The content of stearic acid decreased possibly related to the formation of unsaturated fatty acids and volatile compounds, especially aldehydes, such as 2-hexenal. In fact, key identified volatile compounds included 2-hexenal and hexanoic acid. Regarding secondary metabolites and functional properties, these significantly decreased as maturity stage advanced, only the total carotenoid content significantly increased (0.083–0.148 m...

TiO2 nanotubes were synthesized by alkaline hydrothermal treatment of TiO2 nanoparticles with a controlled proportion of anatase and rutile. Tailoring of TiO2 phases was achieved by adjusting the pH and type of acid used in the hydrolysis of titanium isopropoxide (first step in the sol-gel synthesis). The anatase proportion in the precursor nanoparticles was in the 3–100% range. Tube-like nanostructures were obtained with an anatase percentage of 18 or higher while flake-like shapes were obtained when rutile was dominant in the seed. After annealing at 400°C for 2 h, a fraction of nanotubes was conserved in all the samples but, depending on the anatase/rutile ratio in the starting material, spherical and rod-shaped structures were also observed.

BACKGROUND: The consumption of fruits, mainly berries, has been associated with beneficial health properties. These properties would be related to the quantity and quality of the metabolites present. Some native berries from the Andes, such as Andean elderberry, would be an important source of metabolites with bioactive properties. OBJECTIVES: To evaluate at the physico-chemical and metabolomic level the characteristics of the elderberry from four different high Andean regions, and to determine their bioactive potential through in vitro tests. RESULTS: Significant differences were found in the evaluated characteristics according to the Region of procedence of the fruit. Glucose was the main sugar for all berry samples, followed by fructose. Among the most important organic acids, citric and malic acid were found. Elderberry from Apurimac presented the highest content of total sugars and ...

The present study deals with the form like the college student they conceptuan to the corruption, identifies corrupt acts within its faculty and propose solutions, in function to sex, cycle and academic faculty to which they belong. The sample was of 931 representative to the 0,03 of error margin, distributed by academic faculties. The selected sample randomly, answered a questionnaire of three questions, previously validated semantically; soon in greater groups of ten students it was not talked about his answer with the intention of knowing the trustworthiness the same ones, finding a correlation of the 0,90 between the opinions deepened in the dynamic session with his answers written in the questionnaire. They excel results, with respect to the concept of the corruption: 8% say that it is transgression of norms, to 11% abuse of office, 15% like a crime, for 9% is a disease, for 37% ben...
