Scallion (Allium fistulosum) is a highly perishable green vegetable due to its moisture content, its high metabolic rate and their poor conditions of post-harvest during to harvest and transport. The objective of this research was to determine the relationship between visual deterioration´s product and changes generated in the mechanical and acoustic properties of the same. The scallion grown in Aquitania, Boyacá Colombia was stored under different conditions of storing: vacuum packed (10 mbar) and unpacked (HR 68%) and storage temperature 4 ºC and 16 ºC until deterioration by visual appearance. The acoustic mechanical changes in firmness, crispness and fracture for unpacked scallion and stored at 4 °C occurred on day 15 of storage, and visual deterioration on day 13. For the unpacked product and stored at 16 °C, the biggest change was presented at sixth day. The vacuum packed prod...

The application of edible coatings obtainable from alternative biodegradable materials has gained attention as a promising treatment to prolong the shelf-life of fresh-cut vegetables. Thus, this work aimed to develop a biodegradable coating based on fruit and vegetable residues flour. Immersion coating strategy was studied on the quality of minimally fresh-cut carrots during refrigeration storage by means of weight loss, color variation, pH, titratable acidity and soluble solids content. Better performance was obtained for coated carrots, which exhibited a tendency to have lower whiteness index than uncoated counterparts and enhanced overall quality. Despite a drop in color saturation expressed by chroma values (varying from 59 to 46) was observed, color index presented a positive value for all samples (varying from 13 to 15) indicating orange color preservation throughout storage. Altho...

Gamification from the use of platforms in virtual environments, has served for various studies with findings in structural learning. However, there is little evidence in the use of formal gamification platforms that include cognitive conflict from its pedagogical utility. The research has been carried out applying an experimental design with pretest and posttest measurements. We apply two types of cognitive conflict which we call Gamification Packages / Cognitive Packages. We used formal gamifiers (Mural.ly, Mentimeter, Google Jamboard, Kahoot!), applied in three experimental comparison groups of 150 students (M = 13,2 years; SD = 2,03). Reading, math, reasoning, and research science assignments were assessed. The findings reported greater effects in the group that received the Gamification Packages, secondly, the effects of Cognitive Packages,

In this paper, the processes expressed with verbs of movement in Chanka Quechua, from the Ayacucho area, are briefly presented. Since Quechua is an agglutinative language, the aim of this paper is to analyze the function of suffixes from the semantic point of view. For this purpose, our theoretical framework is based on the contribution of cognitive semantics and on the relationship between semantics and grammar proposed by Moreno Cabrera (2003). The results of this work aim to classify and determine how the suffixes -man, -manta, -kama and -ta act in sentence constructions of movement.

In Huanuco Quechua, there is an alternation in the use of the direct evidential {-mi} within sentences describing maintenance processes. The main objective of this work is to describe such evidentiality in processes of internal and external experience, as well as in others that refer to a notion of control that transmits certainty about the veracity of the statement in an alternate way. As explained by Floyd (1997), in the semantic network of such particle are grouped uses that at first glance may seem incompatible, but are related. For the analysis, formalizations of formal semantics are used (Montague, 1970), which give an account of the syntactic structures involved in the states and the processes derived from them. It is concluded that the use of the suffix '-mi' has an alternation motivated by semantic factors oriented to the experience gradually.

Evaluate the effect of gaseous ozone on physicochemical characteristics, molds and yeasts count and overall appearance of granada. Wonderful variety fruits of granada was collected in a glass chamber where the gas is injected using ozone generator equipment with flow of 500 mg / h and a digital meter for measuring the ozone concentration. A central composite design rotable (CCDR) was used to analyze the effect of the concentration of ozone gas and storage time (p < 0.05) on weight loss, firmness, shell color, soluble solids, mold and yeasts count, total anthocyanins content and overall appearance. It was determined that the concentration of ozone gas had significant effect on the responses studied variables. The quadratic model provided the best fit of data. It was established that the concentration of ozone between 40 - 50 ppm, it allows for the lowest weight loss, low count of molds...

This paper proposes a procedure to minimize electrical losses present in industrial systems, through a specific program developed for this purpose, based on Genetic Algorithm, and written using MATLAB instructions.The minimization is realized with the placement of shunt capacitors connected to the buses. For validation of the proposed method, it is considered accuracy and speed, and the developed program´s results are compared with the results produced by traditional programs. The program avoids leading power factor at the bus connected with the power distribution company and the user may determine buses where he does not want the installation of capacitors. The Genetic Algorithm's fitness, responsible for guiding the optimization process, is the active power loss. Finally, the program is applied to minimize active losses present at an industrial system, 38 buses.

Small and medium-sized companies seek to improve and innovate in all their different processes, since there is more competition, and they all seek to be leaders in the sector in which they operate. However, a problem that involves the entire distribution chain, as well as the profitability of the business, is the return of merchandise. The main objective of this research study was to propose an improvement proposal in distribution management to enhance the number of returns in a wholesale company for the traditional channel using the SMED, Lean Six Sigma and Demand Forecasting. The secondary objectives of this implementation were to analyze and understand the root causes of this problem to address it in the best possible way using diagnostic tools such as the Pareto Diagram and Value Stream Mapping. Likewise, to quantify and measure the impact of this indicator within the company through...

This article highlights the importance of the formal dimension of legal systems for the full realization of the purposes of Law in a society, in view of the changes they have undergone due to the process of their constitutionalization. Based on the systemic theory of life, which highlights the form and pattern of organization of living beings, and projecting it to social systems, Law is presented as an emergent property of social systems, defined from its forms, on which its effectiveness depends.From this theoretical framework, it also analyzes the change of paradigm in the theories of Law and suggests that the identity of legal positivism must be reconstructed around the formal dimension of legal systems to maintain its validity in current debates.Finally, a reflection on the moral commitment of the jurist to the forms and pro...
