The present article proposes to design a model that provides a generic architecture which acts autonomously in public works contracting selection processes, in order to generate an automated decision criterion in the event of a tie. For the Simplified Tender selection process, in case of a tie, it is proposed to choose the bidder by means of an electronic lottery based on a controlled randomization system of encryption and transformation. For the Public Bidding selection process, in the event of a tie, the bidder is chosen by means of a predicted compliance index according to the behavior of the companies when executing similar infrastructure projects. To this end, a model that predicts the probability of success or failure of the bidder to execute a project before initiating it is generated, using artificial neural networks as an analysis tool. This paper reviews the common characterist...

There are many studies of digital technology in teachers and students, however, in parents the previous literature is scarce, possibly because the importance of information technologies in this population had not been considered, even more so in circumstances in which They became co-protagonists of the educational processes in virtuality. The study aimed to apply workshops to improve basic digital skills in initial education. It proceeds with the pre-experimental design (pre- and post-test) for a sample of 42 participants selected by intentional non-probabilistic sampling and as a relevant result, the majority of the participating subjects raised the initial averages by 11 points, findings verified after the application of the program. From the study it is concluded that a determining cause of the announced weaknesses is due to the fact that the participating subjects do not correspond t...

The globally distributed necrotrophic fungus Macrophomina phaseolina is the causal agent of economically important crop diseases such as soybean charcoal rot. This fungus secretes a wide variety of proteins and metabolites that allow it to invade the plant and initiate the infection process. The role of fungi secreted proteins with hydrolytic activity in the infection process has been extensively studied; proteins without enzymatic activity could also play an important role in this process. The analysis of total proteins would allow to broaden the knowledge about this pathogen and establish more efficient strategies for its control. The objective of the present work was to evaluate three methods for the extraction of proteins secreted by M. phaseolina. The fungus was grown in potato dextrose broth (PDB) and Czapek-Dox (CZP) with and without soybean leaf supplementation. Proteins were ext...

A LARGE PART OF THE WORLD'S POPULATION IS SUPPLIED WITH DRINKING WATER FROM SUBWAY SOURCES. DURING THE LAST FEW YEARS, GROUNDWATER NITRATE CONCENTRATIONS HAVE INCREASED CONSIDERABLY. THIS WORK PROPOSES THE REMOVAL OF NITRATES FROM BRACKISH GROUNDWATER AND A MODEL SOLUTION BY ELECTRODIALYSIS. TO EVALUATE THEIR EFFECT ON NITRATE REMOVAL AND ENERGY CONSUMPTION, THREE FACTORS WERE SELECTED WITH THREE LEVELS FOR EACH: NITRATE ION CONCENTRATION (50, 200 AND 500 MG/L), APPLIED ELECTRICAL POTENTIAL (5, 10 AND 15 V) AND FEED FLOW ARRANGEMENT (A, B AND C). THE RESULTS SHOWED THAT THE MOST INFLUENTIAL VARIABLE WAS THE ELECTRICAL POTENTIAL, THE INCREASE OF THE POTENTIAL (15 V) LED TO A CONSIDERABLE INCREASE IN NITRATE REMOVAL (92.5 %). THE BEST CONDITIONS FOR NITRATE REMOVAL FROM THE SYNTHETIC SOLUTION WERE AT AN ELECTRICAL POTENTIAL OF 15 VOLTS, INITIAL NITRATE CONCENTRATION 200 MG/L AND THE FLOW A...

This work describes the isolation and selection of bacterial strains of the genus Pseudomonas in Cetrimide, Acetamide and King B Agar media, from effluents of the leaching process and from the tailings deposit of the gold ore processing plant, Caraveli - Arequipa. Subsequently, the adaptation was made in Modified Mineral Medium (M9M), to different concentrations of sodium cyanide, to evaluate the tolerance and degradation of the CN- radical. The results of sowing in different nutrient media allowed us to observe changes in coloration with a change from clear to intense red in Acetamide Medium and from clear to fluorescent green in King B Agar Medium, revealing the presence of P. pseudoalcaligenes bacteria. Similarly, during the adaptation process of a strain whose initial cell population was 2.0E+06 CFU/mL, in media supplemented with 50, 100, 150, 200 and 250 ppm of Free Cyanide, at the ...

This research aimed to optimize the microwave popping process of 5 cultivars of ñuña beans under different moisture content. This work was divided into two stages: determining the optimal time and microwave power for maximum popping and studying the effect of initial grain moisture content on popping percentage. For this, grains were conditioned to 9%, 11%, 13% and 15% of moisture content. The results suggested that only the cultivars “Vaquita poroto”, “Negra” and “Jabona” cultivars reach the highest popping percentages selecting optimum microwave power and process time. In addition, this work found that for every studied cultivar, moisture content between 9 to 11% w.b (wet basis). is suitable to maximize popping percentage. Moisture contents greater than 13% w.b. drastically reduced the popping percentage but increased expansion percentage. In conclusion, this work recomme...

In this investigation the degradation of a methylene blue sample was evaluated using the principle of the homogeneous Fenton Like process where iron as a catalyst was recovered from a synthetic sample of acid mine drainage by selective precipitation. Globally, acid mine drainage is considered an important residue of extractive mining and its uncontrolled dumping has negative effects on the ecosystem. Recovering a waste and using it as input to treat another is a relevant opportunity. Selective precipitation of iron was performed using a saturated solution of calcium hydroxide. The precipitated iron (III) hydroxide was solubilized with sulfuric acid to obtain iron (III) sulfate and then was used as a catalyst in the tests of degradation of methylene blue having as variables the amount of iron (III) sulfate, hydrogen peroxide, pH and time. All tests determined a degradation percentage abov...
