Authors: Marroquín-De Jesús Ángel
Published: April 2024

In the present work, an indirect solar cooking proposal is
shown. The proposal combines three technologies: evacuated
tubes, selective absorber, and compound parabolic concentrator
(CPC). The absorber used is an evacuated glass tube, with a
highly selectivity inner surface. The temperature reached by the
solar cooker is approximately 160°C, enough to cover the
cooking needs of all types of food; Irradiance, wind speed,
ambient temperature was measured, food cooking tests were
carried out, using an evacuated tube and a parabolic solar
concentrator; as well as evacuated tube without parabolic solar
concentrator. A compound parabolic concentrator was designed
with an acceptance angle of 15 degrees, the base of the solar
cooker was made with acrylic, the concentrator was made with
simple reflection mirrors, the clips were printed on a 3D printer,
the trays were made with food grade stainless steel, food
cooking tests were carried out, recording the weather variables
every 15 minutes. The development of this evacuated tube
duplex solar cooker project is not only important because it
involves the achievement of an academic purpose, but also
involves a social purpose. It is intended to provide an efficient
and economical solution that is attractive to multilateral
organizations capable of supporting its manufacture,
industrialization and distribution to achieve the massification of
the product with a real and lasting impact

Authors: Escobedo-Márquez Diana Laura
Published: April 2024

For a photovoltaic module to work in optimal conditions,
it is necessary a correct cleaning, as electrical power losses
due to dirt on the module´s surface are estimated to be as
high as 30-40% in dry and sandy climates. In this work,
the design and construction of a dry cleaning system was
made using a cylindrical brush with nylon bristle of 100
cm in length and 12 cm in width, the bristle have 0.3 mm
diameter. The angular speed of the system is 10.58 π
radians per second. The objective is to analyze the impact
of the cleaning system on the electrical properties of a
photovoltaic module. For the experimental analysis, the
brush was adapted to a conventional electric motor, and
the cleanings was on the frontal cover of the photovoltaic
modules. The module was exposed to the environmental
conditions of a desert climate, to perform periodic
cleanings and record temperature and irradiance variables.
The result of the research shows the analysis of the
electrical properties of the module to determine the
influence of the type of cleaning and its impact on the
conversion efficiency.

Authors: García-Rodríguez Carlos Iván
Published: April 2024

Currently there is a global need to generate a sustainable
development model that optimizes the functioning of the
dynamic railway industry and that can be updated along with
technological transformations. The objective of this research was
to analyze the strategies of sustainable development models in
the dynamic railway industry, linking technological
transformation to ensure its long-term operation. On the other
hand, railway systems that operate with well-structured
sustainable development models have ample possibilities of
long-term persistence, however, railway systems that lack this
are destined to fail before the economy that can generate
subsidies detonates. The methodology was carried out by a
mixed analysis for it, it was relevant the application of
quantitative and qualitative methods of parameters of sustainable
development in train systems based on control variables such as
economic, social, environmental, equity, areas. Socio-economicenvironmental, stability, viability and ecological. The technical
data obtained from different sources of scientific information
were the basis for decision-making that contributed to the
formulation of a sustainable development model in railway
systems. The characterization and optimization of the model will
be the subject of future work.
Direct infiltration effects of dimethyl sulfoxide into ovarian bursas on spontaneous
ovulation and the estrous cycle of the rat: antagonism on the type 2 dopaminergic
receptor
Authors: Morán-Perales José Luis
Published: April 2024

We studied effects of microinjection (MI) into ovarian
burses (OB) of infiltering agent dimethyl sulfoxide
(DMSO) on number of ova shed (NOS) and estrous cycle
(EC) of adult female rats with fourth day regular estrous
cycles (REC), and we compared these effects with a MI of
100µg sulpiride solution in DMSO. Between 13:00-
14:00h of different days of EC, CER groups received
20µL of pure DMSO into both OB; the sham groups
received MI with 20µL distillated water (H2O) into each
OB. All rats with MI performed and an intact cyclic rat
group were autopsied in the morning of next estrous
vaginal shown (EVS). Both DMSO and H2O MI does not
modify the EC duration and NOS. Other groups of cyclic
rats received a MI with 20µL sulpiride solution into each
OB and were autopsied at next EVS. Just the sulpiride MI
performed on diestrous-1 day delayed 24h the next EVS,
but that don’t occur in other sulpiride groups. The NOS
were not modified in all experimental group. The DMSO
direct administration in ovarian tissue does not affect
gonadal primordial functions and its use is recommended
like an infiltrating agent of non-polar drugs.

respect to the index of biological maturation in schoolchildren
Authors: López-García Ricardo
Published: April 2024

The aim of this study was to identify the differences in
handgrip strength values and anthropometric
measurements with respect to the index of biological
maturation (IBM) in schoolchildren. A descriptive study
was conducted with a total of 256 schoolchildren (78 boys
and 178 girls) aged 10 to 14 years. Body weight, height
and sitting height (trunk and leg length) were measured
using the ISAK protocol; also, manual grip strength was
evaluated with a digital dynamometer and a formula of
Mirwald et al. (2002) was used to determine the peak
growth velocity (PGV) through the IMB. Subsequently,
the sample was categorized into 7 groups according to
their BMI (-1.5, -1.0, -0.5, 0, 0.5, 0.5, 1.0 and 1.5 years).
Significant differences were found in schoolchildren in the
0.5, 1.0- and 1.5-years group with respect to the -0.5, -1.0-
and -1.5-years groups in body weight, height, trunk and
leg length, and grip strength (p ≤ 0.05). We conclude that
the higher the biological maturation index there is a
tendency for the anthropometry and grip strength values in
schoolchildren to be higher with respect to those with a
lower IMB.
Wax obtained from the insect Dactylopius coccus Costa, study for its application in
natural cosmetic products
Authors: Arroyo-Figueroa Gabriela
Published: April 2024

The insect Dactylopius coccus Costa produces a white wax
that serves to protect itself from the environment, at the
time of harvesting the insect, the wax is separated by
sifting, in intensive production of the insect a large amount
of wax is discarded. Therefore, the objective of this work
was to carry out a physicochemical analysis of three
samples from different producers obtained by the same
method, to determine if it meets the characteristics to be
used in any natural product. The methodology consisted of
determining the organoleptic characteristics, as well as the
color by means of a colorimeter, determination of pH,
melting point, and percentage of humidity. The results
obtained were compared with a synthetic
(microcrystalline) wax used in a cosmetic product, to see
if it could be substituted by the analyzed wax. It was found
that it was possible to substitute the synthetic wax for the
natural wax due to its conflicting characteristics.
Therefore, it is concluded that this wax can be used in the
elaboration of natural products. Although it would be
necessary to carry out a series of tests of the final product
obtained with and without the wax. To determine if the
substitution is favorable or not.

Consideration of fouling by scaling in the sizing of flat plate solar collector networks
Authors: Lugo-Granados Hebert Gerardo
Published: April 2024

In this work, the effects of fouling on the performance of
flat plate solar collector networks that operate with water
as the thermal fluid are studied, and design considerations
are put forward to be used in the sizing of these systems
from the thermal and hydraulic points of view. The
quantification of the effects produced by scaling is carried
out through a mathematical model that predicts the
deposition on the walls of the tubes. The model considers
that CaCO3 is the only compound present in the fouling
layer. Results indicate that for a volumetric flow rate of
3.78 l/min and assuming a CaCO3 concentration of 250
ppm, in a period of six months, the maximum outlet
temperature that can be obtained in a day falls 1.5 °C and
the pressure drop increases four times. It is shown that it
is advisable to design a network of solar collectors
considering scaling. The case study indicates that to
supply a total flow rate of 48 l/min at a temperature of 70
°C, the design considering scaling requires 220 collectors
and a volumetric flow rate of 4.8 l/min per line with a total
annualized operating cost of $343,300 Mx.
Removal of disperse blue textile dye 56 from water using a metal-organic framework
of erbium
Authors: Mora-Vargas Etnia Valeria
Published: April 2024

The disperse blue dye 56 (AD56) is of the anthraquinone
type and is considered an important source of water
pollution due to the discharges generated by the textile
industry. An efficient way to eliminate it is using porous
materials, for example, metal-organic networks (MOF). In
this work, the adsorption of AD56 with an Er MOF was
studied and synthesized by microwave-assisted method
and using 1,4-benzene dicarboxylic acid (BDC) as an
organic ligand. Physicochemical analysis of the Er2BDC3
was carried out by XRD, FTIR, SEM, and UV-Vis
spectroscopy to determine the dye concentration. Due to
its high porosity, the results show that the MOF can be
reused for up to seven adsorption cycles for the AD56 dye.
The adsorption process changed the structure of the MOF,
obtaining a more pure and stable material in an aqueous
medium. The maximum AD56 adsorption capacity
obtained was 33.97 mg/g after seven cycles. This material
can be used in consecutive adsorption processes and for
other anthraquinone dyes.

Optimizing solar dryer design: A multicriteria decision making approach for
hybrid systems
Authors: Hernández-Domínguez Erick Alejandro
Published: April 2024

Solar dryers are a sustainable and efficient alternative for
preserving agricultural products, offering numerous
benefits for both the environment and the agro-industrial
sector's economy. The objective is to develop a decisionmaking methodology based on environmental, economic,
and social criteria, allowing the acquisition of data for the
design of solar dryers using alternative energy sources to
achieve the hybridization of one or more energy sources.
The Analytic Hierarchy Process (AHP) methodology is
based on breaking down a complex problem into a series
of simple and manageable problems. This methodology
evaluated alternatives based on different criteria and
factors to consider. The AHP methodology was divided
into three stages: the first was to define the problem to be
solved, the second was to determine the criteria, and the
third was to analyze the possible alternatives. This
research provided information for the design of a solar
coffee dryer in San Antonio el Porvenir, Chiapas. The
solar dryer's design was based on criteria proposed by the
producers, such as ease of repair, the product not being in
contact with the ground, and ensuring safe operation due
to the presence of children and women near the drying
process.

Interactive simulator for teaching-learning of page replacement algorithms in
operating systems
Authors: Castillo-Zacatelco Hilda
Published: April 2024

Topics considered difficult for university students taking
some courses in computer sciences could cause them
academic stress, mainly when for this kind of topic, there
is little or no didactic material available to the instructor,
that she could use as a teaching-learning tool. This kind of
tool can help the student to learn or reinforce her
knowledge on her own. In this work, we describe the
proposal of a teaching-learning interactive tool for the
course of operating systems, and it is about the
implementation of a simulator to learn some pagereplacement algorithms in operating systems that allow the
student to identify not only the replacement algorithm, but
also the important elements associated with the
functioning of these algorithms, like the dispatcher, the
processes, the instructions and the clock. So far, a
prototype of simulator that implements the pagereplacement algorithm, called aging, that uses Round
Robin as a dispatcher algorithm has been built. With this
kind of tool, we hope in the future, to contribute to the
decrease of academic stress by facilitating the professor´s
teaching process and to achieve meaningful learning.

Deduction and construction of a discrete probability function (Binomial and
Geometric) with analytical development of expected value and variance
Authors: García-Nava Elizabeth
Published: April 2024

The present work deals with the construction and deduction
of a discrete probability function, where the objective is the
understanding of the mathematical foundations of probability
for its correct application, interpretation and verification in
solving probability problems. For this purpose we rely on the
theory of didactic situations of Brousseau (1997) and
Sadovsky (2005). Teaching strategies are proposed with
didactic model materials that improve student learning by
promoting the analysis and understanding of various
foundations of probability (Panizza, 2003). The importance
of close communication between teachers and students in the
teaching-learning process for the resolution, interpretation
and verification of probability problems is highlighted. The
software used in this research was Wolfram Mathematica,
which facilitates mathematical writing, calculations, and the
construction of graphs using a simple interface. This software
makes work easier by fostering student autonomy in the
development of skills for analysis and problem solving. We
believe that these materials will contribute to the
improvement of teaching-learning processes on the
fundamentals and concepts of probability.

Implementation of a BSN for the detection of activities during the coffee harvest
Authors: Magín-Murillo Dagoberto
Published: April 2024

Currently, Body Sensor Network (BSN) body sensor
networks are generating great interest due to
applications in different scientific and industrial
environments, they form a technology that allows data
acquisition for research and process control. That is
why the design of an architecture is proposed, based on
networks of body sensors for real-time analysis during
the coffee harvesting process because the workers are
subject to repetitive physical movements and thus
generate a knowledge base and a machine learning
model to present the mathematical models with the
intention of justifying the decisions made from the
coffee harvesting activity. The suit consists of two
modules placed on the arms of the people and another
on the thorax, which are the reference points for taking
the data, thus making use of today's wearable devices.
Ergonomic evaluation of work sites in an aerospace maquiladora company
Authors: Ramírez-Cárdenas Ernesto
Published: April 2024

Ergonomics is a discipline that contributes to the quality of
life of people, through the study and understanding of
interactions between humans, the environment that surrounds
them and the profession. The practice of ergonomics in manmachine-environment systems is essential to eliminate risk
factors associated with the presentation of musculoskeletal
disorders (MSD), the reduction of occupational diseases and
comply with current regulations, this being the objective of
the present study. During the investigation, an exhaustive
analysis of the different jobs was carried out and the
ergonomic risk factors present in each of them were identified
(inadequate postures, repetitive movements, excessive forces
and unfavorable environmental conditions) and their level at
through a specific evaluation method. Finally, specific
intervention measures were proposed and applied to eliminate
or reduce the level of risk. These measures included the
redesign of work stations, the modification of equipment,
tools, the implementation of active breaks and the training of
staff in ergonomic practices. In conclusion, the results support
the importance of incorporating ergonomics as an integral
practice in work environments, in order to protect the health
and well-being of workers, as well as improve the efficiency
and productivity of organizations.

Authors: Delgado-Sánchez Ulises
Published: April 2024

The purpose of this paper is to discuss some of the
applications of the interbehavioral model to the system
of educational psychology. Some of its foundations are
exposed, its application as a logic of theoretical
construction, culminating with some characteristics of
its technological application, in continuity with the
theory of behavior, in the science of psychology. The
technological model of didactic discourse is rescued,
and its current and potential contributions in the
educational field are valued. It is concluded that there is
significant potential for the development of
interbehavioral thinking in the field of psychology, but
researchers need more interest in it.
Social context and hardiness in selected national athletes of weightlifting
Authors: Ponce-Carbajal Nancy
Published: April 2024

The objective of this research is to identify relationships between
social context dimensions and hardiness in elite weightlifting
athletes. Methods: The design: non-experimental, cross-sectional
and correlational, the participants were 20 athletes who belong to
the elite as the national team of Mexico, they are between 19 and
28 years of age, M = 22.05 SD = 2.91, 8 men (40%) and 12
women (60%). 2 instruments were used, the first is the
Perception of Factors Related to Excellence in Sport (PFED),
(Simón, 2009) consisting of 54 items 6 variables, coach,
environment and resources, athlete, family, nature of training and
characteristics of the training and the second the questionnaire of
hardiness in Central American and Caribbean Athletes (PRDCC)
(Ponce, 2017; Ponce-Carbajal et al. 2015) of 18 items and three
variables, commitment control and challenge. In the procedure,
a file was created in google forms and coaches who are in charge
of athletes from the Mexican national weightlifting team were
contacted. The statistical analyzes used were frequencies,
descriptive, reliability, and Spearman's bivariate correlations.
Results: Adequate internal consistency in almost all the
variables, between .40 and .92 in the 2 questionnaires. In the
correlations between variables of the social context and those of
the hardiness, relationships were evidenced between the total
resistant personality and the nature of the training with an r =
.767** and the challenge variable correlated with two, the first is
the nature of the training r =.834** and with the characteristics
of training r =.671**. Conclusion, the relationships between the
variables of the social context and the resistant personality are
confirmed.
An approximation to statistical analysis of recession curves of a karst system in a
plain
Authors: Gonzalez-Herrera Roger
Published: April 2024

A number of models exists to analyze discharge recession curves
(RC), such as Boussinesq (BM) and Maillet (MM) models,
which were derived from theoretical equations of groundwater
flow. This paper presents the results of a study, analyzing water
table recession curves, whose objective was to determine the
model that best represents the dynamics of the karst aquifer in
the northern plain of Yucatan, Mexico. The above was achieved
defining statistical criteria to select the model; implementing a
statistical analysis strategy to compare the estimates of the
parameters of greatest hydrological interest of the chosen decay
models. Two scenarios were considered for the analysis: I.- Two
wells with the same time intervals with standardized data of:
different initial hydraulic head (ho); similar ho; modified ho. II.-
A single well, starting from an established hydraulic head and
discharge in the same period of time. Numerical methods were
used to fit models to the observed RCs and a maximum
likelihood function for parameters estimation. Statistical criteria
were established to choose the best model. The Boussinesq
model proved to be the most appropriate, whose estimates of the
parameter α were explored, using fixed values of the parameter
n. The comparison between the estimates of α was made based
on hypothesis tests (t to compare between two values of α and F
for the comparison between more than two values of α).
Quasiprobability distributions obtained by a maximum
likelihood estimator were also used. The best estimates of α(BM)
are obtained with values of the parameter n between 0.5 and 2.
Strain localization instability in seafloor spreading centers of the Carmen Basin,
southern Gulf of California
Authors: Juliá-Miralles Marc
Published: April 2024

This study provides new insights into the geological
evolution of the Carmen Basin (CB) in the southern Gulf
of California (GC). Using high-resolution bathymetry and
seismic reflection profiles, we establish a plate-kinematic
framework for this oblique-divergent rift system. By
analyzing the crustal composition, we investigate the
growth of the bounding transform faults and their role in
accommodating transtensional shearing. We propose that
the mantle upwelling beneath the CB is a northward
extension of the East Pacific Rise. The CB consists of
three sub-basins with distinct geometries, morphologies,
and evolutionary histories. While the southern and central
sub-basins are mostly abandoned, the northern sub-basin
is currently experiencing seafloor spreading. This is
supported by the presence of younger oceanic crust,
approximately less than 1.5 Ma, juxtaposed with older
oceanic crust that aligns in age with the nearby Guaymas
and Farallon basins to the north and south, respectively.
Our findings also indicate favorable geological conditions
in the CB for the development of hydrothermal systems
similar to those observed in the neighboring Guaymas and
Pescadero basins in the southern GC.
Economic and environmental dispatch of power systems: Minimising CO2 emissions
by integrating renewable energy sources
Authors: García-Guzmán José Miguel
Published: April 2024

This paper analyses the impact of the integration of
renewable energy sources on the economic and
environmental operation of power systems (PS). The
models of renewable energy sources, as well as the
generation cost function and Carbon Dioxide (CO2)
emissions are integrated in an Optimal Power Flow (OPF)
formulation in order to obtain a non-linear multi-objective
optimisation model, which considers economic and
environmental aspects. This OPF model, having integrated
the models of renewable energy sources, allows to
evaluate the impact that these energy sources have on the
minimisation of generation cost and CO2 emissions. In this
work, the multi-objective OPF problem is solved using
weighting factors for the two functions considered in the
global objective function. Several case studies are carried
out to evaluate the effect of the integration of renewable
energy sources on the economic and environmental
operation of power systems. The results of the case studies
show that renewable energy sources reduce generation
cost and CO2 emissions.

Talking about financial education today is more common,
credits, exchange rates, solvency, liquidity are terms that
people of adulthood often use, this research was carried
out with students from a public University in the South of
the State de Sonora specifically with the students of
Industrial and Systems Engineering, an instrument was
applied to them that is composed of 52 items that include
36 multiple choice questions, 8 about their opinions and
decisions and 8 questions about sociodemographic data, it
was applied to a sample of 170 subjects. The results with
the greatest impact, it was found that the level of financial
education is low, that the youngest subjects and those who
have never worked have a lower level than those who have
been part of the population economically for more years
active, women denoted a lower level of financial literacy
and the category with the lowest score was the one that has
to do with investments
Technology transfer through the development of a system for teacher evaluation
Authors: Rodríguez-Campos Juan Carlos
Published: April 2024

This research is carried out at the School Normal Official
(ENOI) for the Research area in charge of collecting and
managing the data resulting from the evaluation of
teachers. Currently, this department does not have a
specialized software system for this process (it is carried
out manually), for these third-party technologies are used,
which are Google Forms and Microsoft Excel. Due to this,
a large number of failures have occurred in the process,
among the most frequent those related to the integrity,
consistency and redundancy of the data. This results in a
considerable loss of time, taking into account that the
institution has 66 professors and for each one 2 documents
are generated (1 Excel and 1 Word), in addition to 4 more
spreadsheet documents to carry out the analysis. of the data
and finally 4 documents for presentation of the results.
Giving a total of 140 documents to be generated only by a
single person. Taking these data, it is essential to manage
the information, this allows to meet the needs of the
institution in the shortest possible time, allowing strategies
and work plans for the academic area to be carried out.
ICTs give us the opportunity to create, modify and store
information. Its development has evolved along with
society, knowledge and education, allowing access to
information at any time. The objective of this project is to
develop an information system as a support tool to improve
evaluation processes and provide a follow-up of teachers
visualizing their academic work.
