Aqueous extractions were performed controlling the pH with CaCO3 and Ca(OH)2, using as clarifiers activated coal and activated clays in cold and warm solutions to obtain best results with cold bentonite, warm activated clay and warm activated coal. Analytical results were compared with a commercial sample of stevia.

The current article presents a thematic review about the state of the art on family resilience articles published in spanish. Starting from the risk and protective factors, it moves toward a definition of resilience, as well as the emergence of the construct. Besides, there are described the components of the resilience approach, such as the salutogenic and ecological models and positive psychology. Family resilience is characterized from the systemic approach and the family stress theory, as well as the main family resilience processes. Is argued on the relevance of the model to approach to topical issues. Various publications are reviewed by types of study: cualitative and cuantitative researches, and review articles. Conclusions and recomendations emanating from the thematic review are presented to finish.

In large urbanized cities, a major problem that affects the economy and health of all citizens is vehicular congestion. This is because the traffic light cycles are not adequate. In the present study, we seek to optimize traffic light cycles based on simulation, in order to improve vehicle flow. For this, the PTV Vissim 9.0 software was used as a simulator and the Synchro 10.0 software to determine the initial optimal traffic light cycle. Through several runs and having as variables the length of queues, delay times and the average speed, the optimal traffic light cycle could be found for the study area. The results obtained reflect a 14% reduction in delay times and 10% in queue lengths. On the other hand, the average vehicle speed increased by 10.56%. All this represents an improvement in the service level of the study intersections.

In this work dehydration of paprika(Capsicum annum L.) in solar and cabinet was compared, 276 and 353 ASTA color respective1y was obtained. Therefore the high ASTA color is produced, when dehydration is carried out in cabínet dryer.

The yacon root is a member of the sunflower family. The roots of yacon has inuline. lnuline is a polyfructosane, which helps to moderate blood sugar levels (pass through the digestive tract unmetabolized). Yacon therefore has considerable value to dieters and people with diabetes. The quantitative analysis shows mineral macronutrients (Na, K, Mg, Ca, P). and micronutrients (Fe, Zn, Mn). The qualitative analysis shows very important secondary metabolites (amino acids, carbohydrate, reducing sugars, flavonoides)

Seeds of chirimoya and guanabana from the communities of Cumbe and Callahuanca - Yauyos, Lima were analyzed. The extraction of natural toxic was realized using ethanol as the optimal solvent, after several solvent tests, phytochemicals analysis identified :saponins, coumarins, tannins, quinones and essential oils, mostly castor oil which was confirmed by FTIR spectra. Qualitative analysis results identified: PO4(3-), AsO4(3-) and others. Toxicological tests extracts applied on larvae and fruit flies finding levels of mortality as 88% to 94% on chirimoyas and guanabanas respectively.

We report documented records of the Marañón crescentchest (Melanopareia maranonica) in six localities. These have hydrological connectivity with the middle basin of the Marañón River, in the provinces of Celendín (Cajamarca) and Luya (Amazonas), Peru. The records were obtained through occasional encounters, biological evaluations and intensive searching, between 2017 and 2020. These new records are between 1111 and 2074 m in elevation, exceeding its known altitudinal range by more than 1000 m. A total of 39 individuals were registered (11 females, 12 males and 16 indeterminate due to the fact that only auditory registration was made). We expanded the known range with respect to the published records by 121 km in the Cajamarca department and 98.2 km in the Amazonas department. Appropriate habitat for this species is protected in 5290.12 ha of the Marañón Seasonally Dry Inter-Andean...

Eating mushrooms are an alternative, which provide high biological and nutritional values, because of their proteins and the high level of their macro nutrients.

En el presente trabajo desarrollamos y adecuamos una tecnología de cultivo y producción de hongos comestibles.
