Regulation of enzymes with identical subunits on the example of Transketolase
Authors: Olga N Solovjeva
Published: March 2022

The molecule of transketolase is a dimer with structurally and functionally identical subunits. Its active sites are located in the region of intersubunit contact, which has been shown also for other thiamine enzymes. This leads to the reciprocal influence of active sites in the binding of cofactors and during catalysis. In this review, it is shown that the functional non-equivalence of the active sites of transketolase from Saccharomyces cerevisiae is initially formed upon the binding of the first cofactor, a divalent cation, not thiamine diphosphate, as previously thought. An attempt was made to find the reason for the differences between catalytic measurements and crystallographic data on the possible part-of-the-sites reactivity of the functioning of transketolase. At the same time, the difference in the amplitudes of dichroic absorption during the binding of reversibly and irreversibly splitting substrates has nothing to do with the flip-flop mechanism. It was also shown that with an increase in the concentration of substrates, a sharp decrease in activity occurs, which is explained by a switch from the simultaneous binding of the substrate in two active sites to its alternate binding both in one-substrate and two-substrate reactions. This fact could also be the reason for the rejection of the flip-flop mechanism of catalysis by transketolase. The mechanism may be similar to human transketolase, which may have clinical application.

Authors: Álvarez Díaz Patricia , Sopeña Vallina María Elena
Published: March 2022

This article recovers and documents the origin and development of the practical experience carried out during the academic year 2019-2020 in the Public-School Virgen de las Mareas (Avilés- Asturias). Faced with the situation of educational segregation that has been going on for years, a collective process of reflection and intervention is initiated to seek socio-educational improvements in the educational community, valuing the strength and power of positive interactions, inter-institutional cooperation and the participation of families and the community, with the common interest of enhancing the quality of public school and the inclusiveness of the neighbourhood. In the first phase of the social practice, one of the objectives of this process was to generate participatory structures. Another purpose has been to join efforts and create a network by establishing alliances between social actors and entities, promoting spaces for dialogue and exchange of knowledge with the aim of transforming the socio-educational reality of the center. The long-term objective of the intervention is to promote a dialogic learning model. Education is a possible field of action for Community Social Work, due to its potential to promote social equality and educational inclusion of people, as well as to generate a sense of community in society.

Authors:   Louisiana Tech University, Duong Bao , Lee Jaeung , Ayaburi Emmanuel , Jin Sung ,   University of Texas at Rio Grande Valley,   Metropolitan State University
Published: March 2022

To examine users’ intention to disclose detailed information on Mobile-Based Online Dating Apps (MBODAs), we adapted Privacy Calculus Theory (PCT) to develop our research model. We posited perceived members’ trust propensity as a central factor connecting its antecedents with users’ information self-disclosure intention. We examine a) the impact of users’ perceived benefit, perceived risk, electronic word of mouth (eWOM), and prior experience on members’ perceived trust propensity, and b) the impact of perceived members’ trust propensity toward users’ information self-disclosure intention. Analysis of MBODA users’ responses indicates that perceived benefit has a positive effect on perceived members’ trust propensity, while perceived risk has a negative effect. Members’ experience positively influences perceived members’ trust propensity; however, eWOM does not show any effect on perceived members’ trust propensity. Finally, perceived members’ trust propensity is positively associated with information disclosure intention. Implications along with limitations and future research directions are discussed.

Authors:   Fordham University, Demissie Dawit , Alemu Daniel , Rorissa Abebe ,   The Sage Colleges,   University at Albany, State University of New York
Published: March 2022

Educational institutions are temples of knowledge that require the utmost safety and security. To ensure that, they are implementing safety measures, including the use of personal safety devices. Adoption of such devices is uneven and not well understood. The main focus of the current study is to investigate the adoption of Peace of Mind (POM), a personal safety device, by students at a liberal arts college in the United States. The Unified Theory of Acceptance and Use of Technology served as the theoretical framework. Findings from a sample of 405 students confirmed that performance expectancy, trusting belief, facilitating conditions, and social influence had direct effects on the students’ behavioral intention to use POM. Based on our findings, we discuss concrete implications for various stakeholders such as higher learning institutions and businesses involved in the innovation and diffusion of personal safety devices. We also make specific recommendations for future research.

Published: March 2022

Information System Security (ISS) research has been identified as an area that IS researchers can and should contribute to. Our research in this area, however, may not yet demonstrate an ability to do better than experts and professionals in the field. This paper explores the last decade of ISS research across a selected basked of journals to determine how ISS research is continuing to fit into the broader base of IS topics. Additionally, we seek to explore the level of analysis and the subjects sampled with a focus on the role of students with respect to quality and generalizability. Finally, we look to better understand the role of the artifact in this research, and the types of artifacts that researchers are focusing on. We find that with a nearly 200% increase in ISS articles over the prior decade, with a strong focus on individuals and the firm/organization, that ISS research is an increasing and thriving area of IS research.

The aim of this research is to identify the factors associated with the match result and the number of goals scored and conceded in the English Premier League. The data consist of 17 performance indicators and situational variables of the football matches in the English Premier League for the season of 2017-18. Poisson regression model was implemented to identify the significant factors in the number of goals scored and conceded, while multinomial logistic regression and support vector machine methods were used to determine the influential factors on the match result. It was found that scoring first, shots on target and goals conceded have significant influence on the number of goals scored, whereas scoring first, match location, quality of opponent, goals conceded, shots and clearances are influential on the number of goals conceded. On the other hand, scoring first, match location, shots, shot on target, clearances and quality of opponent significantly affect the probability of losing; while scoring first, match location, shots, shots on target and possession affect the probability of winning. In addition, among all the variables studied, scoring first is the only variable appearing important in all the analyses, making it the most significant factor for success in football.
Denetimsiz Anomali Tespiti Yaklaşımı ile Düşme Algılama
Authors: SÖZER Abdullah Talha
Published: March 2022

Yaşlı nüfusunun hızla artması ve yaşlılığa bağlı olarak karşılaşılan fiziksel, duyusal ve bilişsel gerilemeler, düşmeyi her geçen gün büyüyen bir problem olarak karşımıza çıkarmakta ve düşme tespiti çalışmalarının hız kazanmasına sebep olmaktadır. Günlük aktivitelerin düşmeden ayırt edilmesinden ibaret olan düşme tespiti probleminde, denetimli öğrenme yaklaşımları kullanılmasına rağmen, düşmenin nadir rastlanan ve çok farklı biçimlerde karşılaşılabilen bir olay olması genel bir model elde edilmesine izin vermemektedir. Bu çalışmada denetimsiz anomali tespiti ile düşmenin belirlenmesi önerilmektedir. Denetimsiz öğrenme modelinin elde edilmesinde ve model vasıtasıyla düşmenin tespitinde 35 tip düşme ve 44 tip günlük aktiviteye sahip kapsamlı bir veri setinden faydalanılmıştır. Denetimsiz öğrenme yöntemi olan Gauss karışım modelinin eğitiminde, günlük aktivitelerden toplanan 3-eksen ivmeölçer sinyallerinden elde edilen öznitelikler kullanılmıştır. Test aşamasında model, düşme ve günlük aktivite verileri ile karşılaşmış, modele göre olasılığı çok düşük olan veriler anomali, dolayısıyla düşme olarak kabul edilmiştir. Testlerde düşmeler %90,5 civarında doğru olarak tespit edilmiştir. Sonuçlar düşmenin anomali tespiti yaklaşımları ile belirlenebileceğini ve makine öğrenmesi modelinin elde edilmesi için yalnız günlük aktivite verilerinin yeterli olduğu yaklaşımını doğrulamaktadır.

Authors: KASKUN Songül
Published: March 2022

In the present study, the hydrogen production of wood sawdust pyrolysis catalysed by TiO2 impregnated Al2O3 (TiO2/Al2O3) was investigated under temperatures of 600, 700 and 800 ℃. The catalyst preparation was made by wet impregnation method for enhanced hydrogen-rich gas production from catalytic pyrolysis of sawdust. Characterization and morphology of TiO2 doped Al2O3 nanoparticles were performed using X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) and the gas product was analysed by gas chromatography. The presented TiO2 doped Al2O3 catalyst showed the highest H2 yield in sawdust pyrolysis as 17.04 mol/kg, and gas productivity 0.72 Nm3/kg biomass at temperatures of 800 °C. Furthermore, the carbon conversion rate of the sawdust pyrolysis was detected as 53.6% with the TiO2 doped Al2O3 catalyst. It was observed that TiO2 doped Al2O3 nanoparticles supplementation approximately 50% increased the hydrogen production of sawdust pyrolysis, compared to non-catalytic experiment of sawdust pyrolysis.

Authors: Bikbov Mukharram M. , Zinnatullin Aynur A. , Gilmanshin Timur R. , Zainullin Rinat M.
Published: March 2022

BACKGROUND: Macular holes are among the common causes of irreversible visual impairment. At an early stage macular holes may be asymptomatic which is a pressing problem in the diagnosis of this pathology.
AIM: This work analyzes the prevalence of non-full-thickness and full-thickness macular holes in the population of the Republic of Bashkortostan, depending on the age, gender, and nature of the respondents settlement.
MATERIALS AND METHODS: The Ural Eye and Medical Study was conducted and included 5899 people.
RESULTS: In the study population, macular holes were detected in 64 patients (1.1%, 71 eyes), including non-full-thickness macular holes revealed in 46 (0.8%) cases, and full-thickness macular holes found in 18 (0.3%) cases. The average age of patients with macular holes was 67.809.34 years, which significantly exceeded the average age of individuals in the study population (59.010.7 years; p 0.001). The incidence of macular holes among women was 1.35%, and that of men was 0.81%. In contrast, it was 0.96% among urban residents and 1.34% among rural residents. In the patient population with macular holes, and especially in the subpopulation with non-full-thickness macular holes, a significant predominance of this pathology was registered in female patients and urban residents.
CONCLUSIONS: The incidence of macular holes in the Republic of Bashkortostan was 1.1%, in line with the average global level. Non-full-thickness macular hole predominance among urban residents in the absence of a significant difference in gender characteristics and the prevalence of full-thickness macular holes is a distinguishing feature in the epidemiology of macular holes for the region under study.
Evaluation of the efficiency of preventive examinations of the adult population, aimed at early tuberculosis diagnosis
Authors: Rubis Lyudmila V. , Markelov Yuriy M.
Published: March 2022

BACKGROUND: In Russia, compared with other countries, at least 65% of the population must undergo an annual fluorographic examination for early tuberculosis detection.
AIM: This study aimed to assess the impact of mass fluorographic examinations of the adult population on the main epidemiological factors and indicators of prompt tuberculosis detection.
MATERIALS AND METHODS: The morbidity and mortality from tuberculosis have been analyzed along with the efficiency of its detection during preventive examinations, the proportion of destructive forms of the disease, and the 1-year mortality rate in four federal districts from 2014 to 2019.
RESULTS: For all districts, low efficiency of preventive examinations was registered (1 patient per 2,0005,000 people examined), as well as its strong correlation with morbidity and, in case of its absence, with the coverage of examinations. The change in morbidity and mortality rates over time was independent of the mass screening volume of the adult population. The relative risk indicators of increased morbidity and mortality with a decreased number of examinations were 0.4 and 0.3, respectively. The increased coverage of the population with examinations was not accompanied by an improved indicator of detection timeliness, namely a decreased incidence of destructive forms and 1-year mortality rate. The incidence of tuberculosis is determined by socioeconomic factors, which influence the level and living conditions of the population.
CONCLUSIONS: This study established the low efficiency of mass fluorographic examinations of the population, lack of influence of coverage with examinations on the epidemiological situation, and the timeliness of tuberculosis detection.

Published: March 2022

Disorders of control mechanisms caused by glucocorticoid hormones of adrenal cortex have a significant role in the pathogenesis of infectious diseases, first of all, due to cortisol, one of the key hormones with anti-inflammatory activity. Currently the conception about the mechanisms of cortisol influence, its functional abilities, connection with immune and nerve cells, involvement in cytokine regulation, features of free-radical oxidation has been extended. There has been identified the dependence of cortisol influence upon the isoform, amount and affinity of its receptors on target cells. The present review describes the study results concerning cortisol level in case of the most often occurring infectious diseases in children acute respiratory and intestinal infections, infectious diseases of the central nervous system. There has been noticed a considerable data variability about cortisol level in normal state and in pathological one, however, the majority of articles have detected its connection with clinical manifestations and outcomes of the diseases. The study of cortisol level in cerebrospinal fluid is of a special interest in case of neuroinfections, specifying its direct connection with the disease severity and aetiology that gives new possibilities to develop effective diagnostic criteria. In general, the literature data specifies the advanced study of disorders of hypothalamus-hypophysial-adrenal gland functioning, receptor apparatus of target cells, as well as interrelations of cortisol with immune system in case of infectious diseases to reveal new criteria for diagnostics, course prediction and disease outcome, therapy correction.

Published: March 2022

As part of a broader effort to develop ground-motion data resources for China in a manner consistent with Next Generation Attenuation projects, we develop a database of geotechnical soil profiles and shear-wave velocity (VS) logs for sites having ground-motion accelerometers (this database is referred to as soil profile database [SPD]), and then use that data to develop site parameters. The site information is compiled for stations within the National Strong Motion Observation Network System (NSMONS) of China. This effort is focused on four provinces in western China (Yunnan, Sichuan, Gansu, and Xinjiang), which contribute 871 of 2023 NSMONS stations throughout China. Of the 871 sites, the SPD provides site information for 678 sites, or 78% of the total. To develop the SPD, geotechnical logs and/or VS profiles are compiled for 637 sites. This information is derived from previously unpublished reports and is assembled here in a uniform format and partially disseminated (only approximate site locations are provided). The remaining 41 sites in the SPD have confirmed bedrock conditions at the ground surface. Site metadata and parameters are compiled into a database, included as a supplemental material to this article, that includes the depth to the first occurrence of 0.5 km/s shear-wave velocity (Z0.5), three time-averaged shear-wave velocity parameters (VSe, VS20, VS30), and site classifications based on the Chinese building seismic design code and National Earthquake Hazards Reduction Program Provisions. For sites with VS profiles that do not extend to 30 m, we present region-specific recommendations for extrapolating time-averaged velocities from the profile depth to 30 m. For sites with geotechnical logs but no profiles, we present procedures to estimate VS profiles from which the earlier parameters can be derived.

Environmental care is a topic that has aroused special interest in the process of technological development. There is a great concern about the environmental impact of the non-sustainable projects and the interest in green research is growing to create a resilient global society. It is contradictory that while the impact of technology and industrialization has been highly negative on the environment, green technology has contributed to saving the planet. Green technology includes developments and research to protect the environment, improving the performance of the technology in a “green” manner, restoring the damage to the Earth, and optimizing processes conducive to environmental care.
Strengthening the links between education and the labour market.
Authors: Varvara Lalioti
Published: March 2022

In the wake of the financial crisis and the associated austerity measures, the relationship between education and the labour market and, more specifically, the means for strengthening this, have attracted the attention of various groups of stakeholders at European and national level. This growing interest, which, among other things, has put skills and the skills mismatch at the centre of debate, is largely associated with the viewthat the absence of strong links between education and the labour market is a source of multiple negative outcomes, such as higher inequality and lower social cohesion. In contrast, a closer connection between the two fields is often regarded as crucial to attaining positive outcomes, such as improvements in the labour market integration of individuals and increased job satisfaction.Against this backdrop, the present paper sheds light on the case of Greece in a European context. Drawing on extensive desk research, the analysis reveals, first, that the country has long suffered as a result of poor links between education and the labour market, as exemplified by the relatively high rates of unemployment among graduates of higher educational institutions. Moreover, the foregoing relationship appears to havedeteriorated during the years of crisis and austerity. Second, it is argued that the same period saw the start of a debate on strengthening the ties between education and the labour market, as reflected, inter alia, in the growing importance attached to identifying skills needs and tackling the skills mismatch, and to the promotion of policies in this area. Overall, this trend is in line with broader trends at the European level that favour strong(-er) links between education and the labour market, illustrative of which is the increasing attention paid to ways of dealing with the skills mismatch and the establishment of relevant mechanisms to assist with this. Further action needs to be taken in Greece, however, in order not to jeopardize the progress made and to guarantee that new mechanisms and other existing policies are capable of fulfilling their declared goals.

The Reputation of Machine Learning in Wireless Sensor Networks and Vehicular Ad Hoc Networks
Authors: Pasupuleti Mahesh Babu , Adusumalli Harshini Priya
Published: March 2022

It's difficult to deal with the dynamic nature of VANETs and WSNs in a way that makes sense. Machine learning (ML) is a preferred method for dealing with this kind of dynamicity. It is possible to define machine learning (ML) as a way of dealing with heterogeneous data in order to get the most out of a network without involving humans in the process or teaching it anything. Several techniques for WSN and VANETs based on ML are covered in this study, which provides a fast overview of the main ML ideas. Open difficulties and challenges in quickly changing networks, as well as diverse algorithms in relation to ML models and methodologies, are also covered in the following sections. We've provided a list of some of the most popular machine learning (ML) approaches for you to consider. As a starting point for further research, this article provides an overview of the various ML techniques and their difficulties. This paper's comparative examination of current state-of-the-art ML applications in WSN and VANETs is outstanding.
EDITORIAL: Prácticas contables desde la utilidad para la toma de decisiones
Authors: Lemos de la Cruz Jorge Eduardo
Published: March 2022

Las prácticas contables involucran a las instituciones, los agentes y el saber contable. La multiplicidad de problemas que en la actualidad son abordados por la contabilidad involucra formalmente y para distintos momentos en su desarrollo, a la economía, las finanzas, lo social y lo ambiental. A manera de exploración se construye alrededor de la cultura (y el lenguaje) como objeto posible de representación.

Este panorama diverso, amplía el campo de las prácticas y en especial las actitudes éticas de las personas, como también la disponibilidad de arquitecturas contables que permitan la representación, y dentro de ella la revelación de la información aparentemente suficiente y necesaria para los distintos usos e intereses.

En particular es de interés revisar las prácticas éticas de los agentes quienes a pesar de contar con dispositivos contables para dar cuenta de las implicaciones sociales y ambientales de los hechos económicos financieros, o evidenciar las acciones mismas de afectación y conflicto ambiental, no son relevantes en sus reportes.  La literatura reporta insatisfacción en la revelación de la información centrando la dificultad en las decisiones de los sujetos frente a la construcción de la información.
Energy Efficiency of Container Cargo Flow in Largest East Adriatic Ports
Authors: Barić Mate , Orlović Josip , Šango Leonardo , Pedišić Mateo
Published: March 2022

Modern cargo flow nowadays requires proper analysis in order to optimize the costs and environment
impact. To properly assess the ports at eastern Adriatic region transport energy efficiency and emissions
were analysed, including both sea and land transport. For the sea transport Otrant gate was chosen as
an entry point in Adriatic Sea. The analysed ports are Trieste, Koper and Rijeka as well-established
container terminals and ports of Zadar and Ploče as terminals which in future may provide significant
service. For the land transport, using both truck and train, Budapest was chosen as a final destination
due to its location further in land at similar distance from all selected ports. As a cargo unit one 10
tonne TEU unit was used. The purpose of this analysis was to determine required energy to transport
that one unit and emissions which such transport produce, not a volume or speed of transport. All
the calculations were made using EcoTransIT calculator. The results showed that north Adriatic ports
have one of the best positions in terms of efficiency of land transport, however southern Croatian ports
have to develop transport infrastructure, mainly railroad, to be considered as a notable stakeholder.

Published: March 2022

In this paper, the authors perform a comprehensive literature review on the use of data obtained from the
Automatic Identification System, with an emphasis on vessel route prediction and seaport operations.
The usage of Automatic Identification System vessel’s position data in the vessel route prediction
and seaport operations has been analyzed, to prove that Automatic Identification System data has a
large potential to improve the efficiency of maritime transport. The authors concluded that proper
vessel route prediction and route planning can improve voyage safety and reduce unnecessary costs.
Furthermore, AIS can provide port authorities with early warnings, allowing them to take preemptive
action to avoid possible congestions and unnecessary costs.

To study the effect of comorbid pathology: obesity of degree 2-3 on the level of sex steroid hormones and their receptors in the tumor and its surrounding tissue in patients with endometrial cancer (EC). Materials and methods. In 30 patients with endometrioid adenocarcinoma T1-3N0-1M0 (the main group, 15 females with obesity grade 2-3 (BMI≥35); the reference group 15 females with normal BMI) in samples of the tumor and its perifocal zone taken after surgical treatment, the levels of estradiol (E2), estrone (E1), testosterone (T), progesterone (P4), androgen receptors (AR), progesterone receptors (RP4), estrogen receptors (ERα and ERβ) were determined by ELISA method. Statistical analysis was performed with STATISTICA 10.0. Results. Obese EC patients showed longer healing of postoperative wounds, slow recovery, and more frequent tumor metastasizing to regional lymph nodes. In the tumor samples in all patients, compared with the intact endometrium, the levels of estrogens, testosterone and their receptors were higher. Obesity accompanying the malignant process led to a local increase in the levels of estrogens, testosterone, progesterone and AR, ERα and ERβ in the tumor. In the tumor samples, there were no significant differences from the presence of obesity in the levels of RP4. In the perifocal zone of the tumor in patients with comorbid pathology, compared with the parameters in the reference group, the level of E2, P4 and T was also higher, but the content of all steroid receptors was lower. Conclusion. Obesity aggravates hyperestrogenism and progesterone deficiency in adenocarcinoma and increases its enrichment with the androgen and estrogen receptors with the prevalence of ERα over ERβ that may cause the autocrine-paracrine regulation of the growth and metastasizing of the malignant process in patients with endometrial cancer.

Authors: Sonawane Heena , Sansare Kaustubh , Karjodkar Freny
Published: March 2022

To assess the morphologic patterns of Incisive canal (IC), distance between the IC and buccal cortical plate in partially edentulous patients, distance between the maxillary central incisor (MCI) and IC in dentulous patients and measure length and width of IC on cone beam computed tomography (CBCT) scan for implant placement.

A total of 104 CBCT scans consisting of 52 dentulous and 52 edentulous patients aged between 20 and 60 years were retrospectively reviewed from the archives’ of oral radiology unit. Kodak 9000C 3D unit was used for obtaining these scans. The morphology, location and dimensions of IC was analysed by two observers. The correlation of age and gender with all the variables was evaluated.

The most common pattern found in this study was slanted straight SS (36.5%). A single canal was reported in 95.19% scans. The mean distance from buccal cortical plate to IC was 5.09 while that from MCI to IC was 2.33. The mean canal width of IC in partially edentulous scans was 2.96 while that in dentulous scans was 3.11. The mean canal length of IC was 10.1 in partially edentulous group while it was 10.68, in dentulous group.

The study population is safe for implant placement in regards to the pattern and number of canals of IC and compromised with respect to the bone available anterior to the IC. The implantologists’ needs to be aware of these shortcomings while planning implant in the upper anterior region.
La bioética ambiental como estrategia para conservar la especie humana
Authors: Velásquez Arias Johana Andrea
Published: March 2022

Propósito. El presente ensayo tiene como fin establecer una breve concepción de la crisis ambiental actual y analizar cómo, a raíz de ello, surge el neologismo «bioética» por Fritz Jahr y Van Rensselaer Potter, como referente para una biología de la conservación, de las éticas ambientales y de la restauración ecológica.

Contenidos. La bioética ambiental se propone como base para satisfacer las necesidades de las generaciones actuales, sin comprometer los recursos de las futuras, y es la clave para lograr un desarrollo en donde se considere al medio ambiente, los recursos naturales y los servicios ecosistémicos, como base fundamental para el florecimiento de la especie humana.

Conclusiones. Como conclusión se afirma que es relevante promover estudios que se centren en la necesidad de fortalecer nuevos marcos conceptuales para la bioética ambiental, con el propósito de recuperar, rehabilitar o mitigar los efectos de la crisis ambiental actual. La bioética ambiental debe establecerse como principio para el diseño y formulación de políticas públicas.

Published: March 2022

La quinua (Chenopodium quinoa) es uno de los principales granos de especie domesticada oriunda de los Andes altiplánicos y valles altoandinos. Debido a que sus cosechas no siempre presentan un color homogéneo, en algunas empresas vienen utilizando máquinas clasificadoras para quinua que son adaptadas de otros cereales, cuyo funcionamiento no garantiza la eficiencia deseada. El propósito del estudio fue diseñar y construir un prototipo de máquina que clasifique los granos de quinua según el color deseado. Las partes principales de la máquina incluyen el diseño de la estructura mecánica que comprende tres zonas: alimentación, transporte y proceso y almacenamiento. Las piezas fueron construidas con materiales de acero y algunas piezas con filamento PLA fabricadas con impresora 3D; sistema de control electrónico, utilizando un microcontrolador para la adaptación de la señal de sensor IR y controlar los electroactuadores para la selección de quinuas homogéneas según los parámetros de colores permitidos; y control de funcionamiento mecánico, utilizando dos motores, una para la dosificación de los granos de quinua y otra para el movimiento de la faja transportadora. Para conseguir el mejor rendimiento se realizaron ajustes respecto a la velocidad y cantidad de quinuas, estableciendo a 24 hileras con una elevación de 22 grados respecto al eje horizontal, habiéndose conseguido la meta de 5 kg por hora y obtenido la homogeneidad de los granos de quinua con alta eficiencia y de mejor calidad para su comercialización.
