Growth and Mortality Analysis of the Frailejón (Espeletia pycnophylla) on the Edges of Hydrographic Basins in the Municipality of Cumbal, Nariño, Colombia
In this work the growth and mortality parameters of frailejon Espeletia pycnophylla relocated to the edges of watersheds bordering grasslands and native forest, during 6 months (n = 200) were evaluated. There were two planting sizes: small (frailejon height between 4 and 10 cm) and large (frailejon height between 10 and 20 cm); and organic fertilizer was applied to half of the study individuals. The results show that the general survival rate was 52%, being the frailejones of large size and with fertilization the ones that present less mortality. Despite the fact that, in-field observations, it seems that the fertilizer stimulates the growth indicators (growth of the diameter of the stem, of the root, of the stem and the number of leaves), however, there is no statistically significant difference at the 95% confidence level between the use of fertilizer and the size of the frailejon, with the exception of the growth of leaves

Fuzzy inference system for determining the risk profile of investors in the Colombian financial system
Financial institutions determine the risk profile of investors through surveys that oversimplify the complexity of individual preferences, which limits the portfolio of these institutions. Thus arises the need to use alternative methods to provide greater relevance in the portfolios offered by the financial system. In this sense, the starting point is the following question: how to structure a system to more adequately determine the risk profile of investors? In response, this research develops a methodological proposal based on fuzzy logic, according to which investors are categorized within non-discrete risk scales, considering the vagueness and heterogeneity in the characteristics of each individual. The results show that the proposed fuzzy inference system potentially improves the risk profile classification, capturing the particularities of the investor.

Computational analysis of agroclimatic behavior in the production of beans (Phaseolus vulgaris) generated in the Sibundoy city-Putumayo.
Crop productivity is directed by complex agroclimatic interactions, in this aspect, productive success not only depends on the intensity of climatic stimuli but also on the temporal sequence of these during the crop life cycle, among them very important parameters interfere such as; the temperature, solar radiation and water in the soil, these are the three main meteorological factors that regulate the processes in plants. The objective of the research was to determine the effects of the climatic variables (temperature, precipitation and solar brightness) in the bean crop (Phaseolus vulgaris) of the city of Sibundoy, from an agroclimatic study. The evaluation of the variables that affects the bean crop was made from the Cropwat® simulation model. It was found that in 2008 and 2011 there were no significant changes in the evaluated variables, compared to 2014, where from then on the climatic conditions are affected in a relative way the bean crops, which means that their yield and production is being reduced. It can be concluded that there is a remarkable relationship between the climate and agricultural productivity, due to the increase in high temperatures, heavy rainfall and the intermittence of climatic phenomena; therefore, agroclimatic studies through computational analysis estimates allow inducing the search for the implementation of new adaptability alternatives in the face of climate change.

Analysis in reduction of ibuprofen concentration in aqueous solution by means of direct photolysis with LED-Ultraviolet lamps
In this work, the use of commercial UV LED lamps (395 nm, IP 68 certification, and 0.08 W) was evaluated for the reduction of Ibuprofen (IBP) concentration in an aqueous solution. The measurements of pH and initial concentration of the PPI in the solution were the experimental variables used to determine its effect on the percentage of reduction of the drug. The maximum reduction of PPI concentration reached was 93.64% at initial pH 7 and 20 mg / L of initial PPI concentration, the analysis of the results indicated that the initial pH of the solution does not affect the decrease in PPI concentration, but the pH of the water decreased in each test, which indicates the formation of CO2 and its subsequent dilution in the water, a fact that suggests the mineralization of the IBP. The effect of concentration is relevant until reaching a concentration of 20 mg / L and from this value, the results do not differ, since the number of lamps and reaction time remains constant, in addition, the decrease in pH makes the molecular shape PPI predominates, a fact that affects the degradation path of this pollutant. The energy applied in the analyzed process was 4.8 kWh. The use of commercial UV Led lamps can be an advantage for tertiary wastewater treatment, these lamps are easily available, submersible in water, and lower energy consumption than commercial UV lamps.
