Nephroprotection of p-coumaric acid against sublethal dose of carbon tetrachloride
in Wistar rats: histological evidence
Authors: Macías-Pérez José Roberto
Published: April 2024

In Mexico, chronic kidney disease is a public health
problem, when is diagnosed in advanced stages, the only
treatment options are dialysis, hemodialysis or organ
transplantation, however, the health system does not have
the economic capacity or the infrastructure to fully cover
these treatments. Therefore, the objective of this research
work was to evaluate the activity of the p-coumaric acid
(pCA) as a possible nephroprotective agent against toxic
carbon tetrachloride (CCl4)-induced kidney damage in
male Wistar rats. Renal parenchyma was evaluated using
two stains, hematoxylin and eosin (H&E) and periodic
acid with Schiff's reagent (PAS). The administration of
CCl4 (4 g/kg, p.o., one dose) induced tubular necrosis and
glomerular rupture within 24 h, with loss of microvilli and
basement membranes, with widening of the lumen of the
distal and proximal tubules. On the other hand, pCA (100
mg/kg, p.o., administered 24 h and 1 h before CCl4 and 1
h after this toxic agent) showed nephroprotective action by
reducing the presence of these morphological changes.
Our results suggest for the first time that pCA, when
administered preventively, slows the deterioration of renal
structure induced by acute exposure to a sublethal dose of
CCl4.

Study of the physical-mechanical characteristics of concrete in a concrete-PET
mixture
Authors: Espinosa-Sosa Enrique Esteban
Published: April 2024

In the field of construction materials, concrete is today one
of the most accepted mixtures of materials by the
community. Cement is one of the most used products in
the world, although large cities are already full of large
buildings, cement is still requested in large works. One of
the materials widely used as primary packaging are the
thermoplastic polymers of the so-called PET
(Polyethylene Terephthalate). These materials are
currently very polluting mainly in oceans, seas and rivers.
The properties of polymers could be exploited to reinforce
the properties of concrete and at the same time reuse the
polymer to reduce its contamination on the planet. For this
research project the experimental methodology was
applied consisting of establishing combinations of
concrete-PET materials in different ratio. The results
obtained from the different mixtures that were prepared
from the Flexural Effort tests, it is observed that both in
the mixture containing 0.5% PET and in the one
containing 1.0%, the results of Flexural Effort are higher
compared with the pure mixture.

The objective of this research was to evaluate the influence
of the concentration of phosphoric acid in the impregnation
to obtain hydroxyapatite (HAp) from the recycling of the
eggshell reduce the residues formed in conventional
synthesis; in addition to evaluating the Ca/P ratio in the type
of HAp obtained, in order to test the material in the removal
of dyes. The material obtained was characterized by
Scanning Electron Microscopy, Energy Dispersive
Spectroscopy (EDS) to obtainmorphology and elmental
composition, Fourier Transform Infrared and Raman
Spectroscopy, to determine functional groups and crystalline
phases respectively. A carbonated HAp was obtained,
increasing the concentration of phosphoric acid (0.5M, 1M,
1.5M, 2M and 2.5M) increases the presence of the phosphate
group in the material; therefore, the presence of carbonates
decreases. It is important to highlight that by Raman it was
not possible to find the presence of phosphates, it is necessary
to analyze the material by other characterization techniques.
Although, with the other techniques used, it was possible to
determine the presence of this in the material.

Published: April 2024

Around software development, there are many variables,
which provide support for calculating different quality
factors or simply for keeping historical data and learning
lessons from previous developments; from these data,
decisions can be made to improve the activities carried out
in processes and in development methodologies. The aim
of this research is to gather and analyze the defects
identified by the development team during the inspections
they conduct in the testing phase, in order to prevent the
same defects in future developments. Additionally, it
involves analyzing the impact that timely detection has on
time and forming high-performance development teams.
Starting from the system development using web-based
programming technologies for users, defects encountered
during the development process are collected and
consolidated into a template based on the ISO 29110
standard. This template is adapted to work with small
software development entities, particularly in the Software
Project Implementation process. The most significant
contribution lies in raising awareness about defect
prevention through the induction provided to software

Administrative and financial diagnosis of miscellaneous stores classified as
microenterprises, in Izúcar de Matamoros, Puebla
Authors: Palma-Bermejo Yetzabel
Published: April 2024

In Mexico, 80% of the tobacconists or miscellaneous shops, also known as “corner
shops”, are considered within the informal occupation. Taking into account that
these microenterprises are a source of employment for a significant percentage of
the employed population, we consider it vital to carry out an administrative and
financial diagnosis, which allows us to establish the basis for the creation of a
business model that allows them to join the sector formal and modernize, which
would be a significant advance for the country Trade is the preponderant economic
activity in Mexico, since it brings together 50% of the country's economic units. Of
the 153 kinds of activities in which the North American Industrial Classification
System (SCIAN) divides trade, ten stand out, which accounts for 56.4% of the
economic units and 47.7% of the total employed personnel. Among the 10 most
outstanding activities of commerce (INEGI, 2009), the activity of grocery stores
and miscellaneous stores, represents the highest percentage of economic units with
31.2% and total employed personnel with 19.2%, that is, every 10 commercial
establishments, three are grocery and miscellaneous stores and for every 100 people
employed in commerce, 19.2% work in this type of economic units. This means
that miscellaneous stores represent a significant percentage of employability
opportunities for people in Mexico and, if something is not done to modernize and
become more competitive, their sales will decrease and, given the competition
represented by the chains Convenience stores, such as Oxxo, will continue to lose
sales until they disappear and, consequently, people who live from this type of trade
will have to look for other sources of income. This research aims to apply the results
of the administrative and financial diagnosis of the miscellaneous stores in Izúcar
de Matamoros, Puebla (542, according to INEGI data), to design a management and
control model that allows them to be strengthened and boost their business
development, implementing a control administrative and financial, which also
contributes to the job stability of those engaged in this commercial activity and
decreases their mortality rate.

SWOT-AHP methodological framework
Authors: Ruiz-Suarez Alison
Published: April 2024

Historically, we know that renewable energies have been
a key element for the development of rural communities
and have addressed social problems. If we talk about the
implementation of renewable energies with the objective
of solving social problems, these technologies will be
understood as the means of intervention to improve a
social, economic or environmental good of a region. The
use of methodologies in project management has the
benefit of organizing and providing tools to reduce the
risks of projects to be implemented in a region. The
purpose of this article is to test the suitability of an
innovative methodological framework that integrates
multicriteria for decision-making and analysis tools
(SWOT-AHP). SWOT allows planners to gather relevant
knowledge from local stakeholders (Uhunamure & Shale,
2021), while the AHP-Hierarchical Analytical Process
allows the prioritization of alternatives. This in order to
prioritize the needs to be met in the community, promotes
social acceptance of the technology and contributes to the
development of rural areas.
Analysis of the simplified trust regime RESICO

Published: April 2024

Individuals and corporations acquire tax obligations when
they initiate an economic activity. The obligation of
individuals and legal entities to contribute to public
spending is established in Article 1 of the Federal Fiscal
Code, where the applicable provisions are indicated; it is
the main basis for the contributions classified as taxes,
social security contributions, improvement contributions
and duties, mentioned in Article 2 of the Federal Fiscal
Code. The timely and proper payment of the respective
taxes avoids being subject to certain tax credits, updates
and surcharges. The SAT is continually looking for ways
for taxpayers to comply with these obligations, adapting
tax regimes to facilitate this process. The RESICO
Simplified Trust Regime is an example of this, which
establishes who can and cannot pay taxes, the
requirements and procedures to comply with tax
obligations. This analysis contributes to the generation of

horizon case
Authors: Perez-Veyna Oscar
Published: April 2024

The value of nature does not escape the interests of those
who cannot conceive the limits of such an important and
vital element. The valuation on nature is developed to
generate a reference and take actions accordingly. In this
regard, the Contingent Valuation method is the most
commonly referred to, but it involves the design of a
structured survey in which the main question is whether
there is a willingness to accept an amount of money in
compensation (DAC) for the loss of an eco-friendly good
or service. systemic or willingness to pay an amount of
money to keep it (DAP). One or the other is defined
without having a single referent and has been taken as a
synonym of the total economic value. For this case, the
problem of justifying the output value (DAP) was raised.
The objective was to develop a methodology that based on
data on household income and expenditure (ENIGH) in
Mexico and applying a percentage to the expenditure per
month, provided a basis for calculating that amount. The
resulting methodology was accepted in the Valuation of
goods and services provided by the Gulf of Mexico, after
the Deepwater Horizon accident.

resource in detail in any region using the annual records of
its wind speed and direction. To demonstrate its
functionality, data from the year 2022 from
Cuatrocienegas, Coahuila de Zaragoza were used,
obtaining the average energy density per hour (MED)
using two analytical methods and the Weibull probability
distribution function (WPDF). The instantaneous power
curve, the histogram of the occurrence of the wind and the
wind rose that shows the predominant direction of the
wind and its trend of change were also presented. In
conclusion, the developed application provides the
necessary information to evaluate the technical feasibility
of installing horizontal axis wind turbines in the analyzed
region.

Natural biopolymers have been of great help, due to the
versatility of their mechanical, biodegradable and
biocompatible properties. They have been adapted for
different uses. In the present work the elaboration on a
laboratory scale of biopolymers of cereals Zea mays,
Sorghum and Triticum is shown, the obtaining of the
starch biomolecules by means of alkaline extraction [1],
edible chemical modifiers such as citric, tartaric and
ascorbic acid were used, glycerin as plasticizer and
distilled water for hydration. Eleven experiments E1, E2,
E3, E4, E5, E6, E7, E8, E9, E10, E11 were carried out
under two drying conditions: room temperature and a
Felisa oven at 30±1°C for 24 hours. Experiments E1, E2,
E3, E4, E7 were made with biomolecules extracted from
the starch of the three cereals mentioned, using citric acid
as a chemical modifier and experiments E5, E6, E8, E9,
E10 and E11 were carried out with standardized starch.

stability in its macromolecular matrix of the biopolymers.
Concluding that the chemical modifier that provides better
physical characteristics such as miscibility in biopolymers
was citric acid compared to the use of tartaric acid and
ascorbic acid. In addition, it was observed that the less
molecular weight of starch biomolecules are used and
stability at a temperature of 30 ± 1°C for 24 hours, a stable,
cohesive and flexible biopolymer macromolecular matrix
is obtained as shown in experiments E3, E4, E7 and E11.
Rosmarinus officinalis extract, complementary testing for quality control as active
ingredient for formulations
Authors: Orta-Martinez Felipe
Published: April 2024

Today contemporary alternative medicine continues to
increase significantly around the world. Taking the above
into account and given the need for new pharmaceutical
formulations, techniques for the extraction of bioactive
compounds from plants have been developed, such is the
case of the extract of rosemary (Rosmarinus officinalis).
The purpose of this work is to evaluate, through official
and unofficial tests from the Pharmacopeia of the United
Mexican States, a rosemary extract tablet. The extract was
obtained by maceration in methanol and a simple
distillation. Subsequently, using the direct compression
method, prepare tablets and then evaluate them and
determine the identity, disintegration, dissolution, titration
and dose uniformity tests established by the Pharmacopeia
of the United Mexican States (from spanish Farmacopea
de los Estados Unidos Mexicanos, FEUM) for this type of
pharmaceutical presentations. The results show that the
tablets comply with the determinations of the
pharmacopeial tests, which indicates that the tablets
prepared in this work are of good quality, from a
manufacturing point of view and can pass the validation
process, so they could be used in the clinic.
Application for the detection of physiopathologies in blueberry crop
Authors: Arroyo-Almaguer Marisol
Published: April 2024

Mexico is the 6th. worldwide producer of blueberry with
48,999 tons; where Guanajuato contributes 11% of the
national total, ranking 7th. producer of the country
(Secretariat of Agrifood and Rural Development, 2020).
One of the main physiopathies that occurs in blueberry
plants is root suffocation, which limits the ability of plants
to breathe through the roots (Generalitat Valencia, 2022).
Identifying the severity of the damage caused by
physiopathies is essential for timely treatment and the
prevention of its transmission; however, it is complex due
to the lack of classification criteria. In this context, an
application was developed whose purpose is to detect the
level of affectation by physiopathies in blueberry leaves,
calculating the percentage of damage severity, using
artificial intelligence (AI). The results allow us to
conclude that AI provides an easy and incremental
progression as it is applied to different varieties of
physiopathies, through the analysis of photographs. The
application is useful for blueberry farmers and greenhouse
owners, providing convenient information for the
prevention and spread of crop diseases and improving
decision-making

A descriptive study about language anxiety while learning English as a second
language
Authors: González-Anaya Ana Gabriela
Published: April 2024

Learning a second language has implications that go
beyond cognitive processes. External factors such as the
individual’s economic situation, and other intrinsic
factors such as motivation, can influence the second
language acquisition. With this study we seek to analyze
the role anxiety can have in order to learn English as a
foreign language. This work is based on a descriptive
analysis which was applied to 1773 undergraduate
students from a University of Guadalajara campus, and
with this study we look forward obtaining information
about the role of anxiety in learning English; in addition
to identifying whether there are any differences in
anxiety levels according to the major students are going
to graduate from. It is intended to contribute to the
knowledge related to the study of a second language, to
determine what factors influence the development of
language anxiety, and how it could be possible to work
aiming to reduce it while ensuring that the students can
learn a second language in a more effective and
meaningful way.

Technological University of Guanajuato (UTSOE), a
public university with in-person classes. It focused on the
impact of distance education resulting from the COVID19 contingency, during which face to face classes were
suspended at all levels. Surveys were administered to
eighth and eleventh- semester groups during the
corresponding period of January - April 2021, from the
food processing engineering program. The research
investigated the effectiveness and efficiency of the
adopted Virtual Teaching-Learning Environments. The
data collected were coded and analyzed using Excel 2016
and IBM SPSS Statistics V21, through descriptive
analysis. The study revealed that students' motivation has
significantly decreased since the beginning of the
pandemic, with a majority experiencing at least one
disorder, and 48.6% being at risk of dropping out.

Design and experimental study of systems for the regeneration of aqueous CaCl2
solutions using solar energy
Authors: Carrera-Arellano Ethson Uriel
Published: April 2024

Desiccants are capable of extracting or releasing water
vapor from the air, in relatively large quantities. It is
important from the economic point of view the recovery
by thermal regeneration of these desiccants. Therefore, the
development of a technique for the regeneration of this
type of substance is of technical and economic interest. For
this reason, in the present work, two equipments for the
regeneration of calcium chloride in aqueous solutions
were designed, built and experimented with, one with a
flat surface and the other with a stepped surface assisted
by solar energy as a heating medium. This process was
monitored through various temperature and humidity
sensors to know the operating conditions inside the
regenerators, as well as the environmental conditions
throughout the experiments through a climatic and
solarimetric station. During the study it was observed that
the materials and dimensioning of both equipment are
adequate. When comparing the temperatures and amount
of water evaporated during the test period, a better
performance was obtained in the regenerator with an
inclined plane, than in the stepped type, which was
corroborated by evaluating the relative density of the
solutions.
