The Impact of Humor on Test Anxiety
Authors:   , Nasr Boulad Samia
Published: June 2024

The present study examined the impact of humor on test anxiety on a sample of Lebanese Middle School students (N= 75) in the 7th grade, between the ages of eleven and twelve, enrolled in a prestigious private school in the French Program. In addition, this study sought to investigate the effect of visual jokes as compared to those of written jokes in a Physics test. The study relied on self-report measures where participants were asked to fill the Westside Test Anxiety Scale before and after having solved their test in Physics. Results were calculated using analyses of variance. The results did not support the expected hypotheses as test anxiety was not specifically reduced by humor with these Middle School students; however, they all perceived humor in testing as favorable.

Authors:   , Alieh Hout Hanadi
Published: June 2024

The current study investigated the relationship between overall job satisfaction and signs of depression in male and female teachers. A sample of 118 teachers from private schools in Beirut completed a job satisfaction survey and the Beck Depression Scale in addition to demographic variables such as age, salary and number of years of teaching. Correlational analyses showed that there is an inverse correlation between overall job satisfaction and depression in this particular sample. Regression analysis between the variables of job satisfaction and depressive symptoms showed that nature of work subscale is the major predictor of depression. Analyses of variance indicated partial significance regarding an increase in salary and job satisfaction. Recommendations for administrators and teachers and suggestions for future studies were discussed.

Negatividad en la comunicación política, indicadores y alternativas: percepciones en la España de 2019
Authors: Rojas Calderón Alfredo Rafael
Published: June 2024

La negatividad se ha consolidado como una tendencia reconocida tanto en el periodismo político como en las campañas electorales. Sobre esta base, este trabajo indaga sobre las representaciones sociales y las motivaciones personales acerca de este fenómeno en España. El objetivo es conocer y analizar las percepciones de los madrileños sobre los usos de la negatividad en la comunicación política, en el contexto de las elecciones generales españolas en noviembre de 2019. El diseño metodológico ha contemplado la técnica de investigación de los grupos de discusión, concebidos mediante un muestreo intencional estratificado por rasgos demográficos, condiciones socioeconómicas y preferencias ideológico-partidistas. Se realizaron durante el período oficial de campaña y después de las votaciones. La investigación concluye que los madrileños identifican y caracterizan la negatividad en las noticias y la cuestionan como una tendencia mediática. En menor medida lo hacen respecto de las estrategias políticas.
Mind maps as an effective tool in “Practical English language course”
Authors: Borysova Nataliia
Published: June 2024

The article considers the issue of using mind maps in the Practical English course. It is emphasised that they help to structure, analyse, understand and memorise the necessary material. With their help, teachers can explain a new topic, systematise information, exercise control, summarise what they have learned, encourage communication, and create supports. This study aimed to consider the concept of “mind maps” and to highlight the possibility of their application in the study of the educational component “Practical English Language Course”. Research methods includes analysis, systematization, and generalization of scientific research, as well as abstraction, idealization, and logical-structural analysis of the use of mind maps in the educational process. It is noted that this tool is also effective for a student, in particular, for systematizing knowledge, for preparing for classes, for test control, etc. The student can actively participate in the educational process, participating together with the teacher in the development of mind maps. The article states that one of the main uses of mind maps is to create visual schemes or diagrams to represent and organize ideas, vocabulary, grammatical structures, or thematic concepts. In the “Practical English Language” classes, students of higher education can use mind maps to create a schematic representation of the studied material, to activate speaking skills, to work with lexical material, with grammatical material, with text material, to present the results of project activities, to conduct brainstorming storming, discussion, debate, etc. Teachers adapt the use of mind maps according to the specific needs and preferences of their students, which promotes active learning, development of critical thinking and effective communication in the classes. The article emphasizes that in classes you can use ready-made mind maps presented in textbooks or on posters, prepare your own samples for class in the form of presentations or reference notes, in the process of presenting the material, build them in class, organize various types of individual and group activities of students with using ready-made mind maps. Their advantages in use by both teachers and students of higher education are indicated. The practical significance of the research is that its results can be used in the process of professional training of future philologists and English language teachers in higher education institutions, as well as for the preparation of scientific and methodological support using mind maps and in the self-educational activities of students

Analysis of groundwater recharge in Nadvirna district by the Korkmaz method
Authors: Klymchuk Ihor , Arkhypova Liudmyla
Published: June 2024

The identification of groundwater sources and the prediction of possible water level fluctuations are crucial, as the study of these indicators is important for understanding the renewal of water resources and their efficient use in specific territorial conditions. The purpose of this study was to identify groundwater sources in the area of Mykulychyn village and assess their changes during the period from 2016 to 2022. The study was based on the Korkmaz method and analysis of data on water level in the well and precipitation level in the study area. The structural analysis of groundwater recharge in the Mykulychyn village in Nadvirna district was carried out using the Korkmaz method. It is established that groundwater recharge in Mykulychyn village is due to precipitation. The correlation between the water flow rate from the source and the water level in the well is demonstrated, allowing for projection of the study results to both objects. The average annual rainfall on the territory was 1,055.7 mm. The results of the linear regression analysis showed a connection between the water level and the total precipitation. The analysis of water level fluctuations in the well revealed that the annual water level recharge varies from 782 mm in 2017 to -254 mm in 2022. This indicates that some smaller aquifers may have dried up in 2022. The average annual recharge for the period from 2017 to 2022 is 347 mm, which is about 32.88% of the average annual precipitation. The results of the study can be useful in practice for water management and planning in Mykulychyn village, as well as in similar geographical conditions
Study of emissions into the atmosphere from the combustion of pellets and solid waste
Authors: Chupa Volodymyr , Zhovtulia Liubomyr
Published: June 2024

The problem of waste is becoming increasingly urgent as the volume of waste and its negative impact on the environment grow. Thermal treatment is one of the most effective methods of reducing the volume of waste, but it also results in the release of pollutants into the atmosphere. Therefore, the study of air emissions from the incineration of different types of waste, as well as pellets made from different types of wood, was the aim of this research. During the visit to the solid waste landfill in Rybne village, waste samples were collected for further research. A comparative analysis of the level of emissions into the atmosphere of a mixture of waste corresponding to the morphological composition of the solid waste landfill in Rybne village was carried out. A comparative analysis was also carried out for the level of air emissions and calorific value of each type of waste, pellets and their mixtures. The study showed that the level of pollutant emissions into the atmospheric air depends on the type of waste and the technology of its incineration. The highest pollutant emissions are observed during the incineration of plastic, rubber and bio-waste. Solid fuels such as wood, paper and textiles emit fewer pollutants. A graph comparing the calorific value of different types of waste and pellets with the levels of air emissions has been developed. The graph shows that, as a rule, the higher the calorific value of the fuel, the lower the levels of pollutant emissions. The results of the study are valuable in practice for improving the methods of household waste utilisation for heat production, in particular, for selecting fuel compositions that minimise the levels of the studied pollutants in the air

GUIDELINES FOR PEDIATRIC CATARACTS SURGERY
Authors: Zia Muhammad  , Motasim Billah
Published: June 2024

Modern cataract surgery seeks to restore a child’s natural visual axis for healthy visual development, achieve the optimalrefractive result to avoid amblyopia, and provide a secure general anaesthesia.In children, subjective complaints about eyesight are uncommon. The white or partly white pupil is the first symptomthat parents often see. Particularly in cases with unilateral cataracts, strabismus may be the first sign, and in newbornswith bilateral lens opacities, nystagmus or poor fixation may be present.Every youngster who visits the eye outpatient clinic must have a complete ocular and systemic examination. Theevaluation of pupillary responses, ocular motility, and visual acuity should all be part of an eye exam. To design thesurgical operation, a slit lamp examination is required to determine the size, density, and location of the opacity. Afundus examination is performed to check for disc and macula abnormalities and pigmentation. To determine if thecataract is congenital, developmental, or traumatic, the parents’ medical history is helpful.
DIAPHYSEAL NUTRIENT FORAMINA IN DIRED HUMAN ADULT LONG BONES OF UPPER LIMB IN PAKISTAN
Authors: Fatima Sherin  , Ejaz Afzal  , Zahid Irfan Marwat
Published: June 2024

BACKGROUND: Large and tiny foramina on long bones allow blood vessels to enter. These foramina, which goby diaphyseal nutrient foramina, are bigger and are found mostly in the long bone shafts, where they enter nutritioncanals that lead to the medullary cavity. These nutrition canals house nutrient arteries and veins, which may be seenin long and irregular bones. These foramina are located in the shafts of long bones and various places in irregularbones. The orientation of the nutrition foramina, which develops quicker than the non-growing end, is determined bythe growing end of the bones.STUDY DESIGN: A cross-sectional StudyDURATION AND PLACE OF STUDY: Department Of Anatomy, Ayub Medical College, Abbottabadfrom jan 2017 to Jan 2018METHODS: The current investigation contained ninety human upper limb long bones. These skeletons were driedand cleaned. Thirty ulnae, 30 radii, and 30 humerii were among them. The anatomy departments of Ayub and KhyberMedical Colleges provided these bones, respectively. It was unknown how old and what gender the bones were. Everybone was examined macroscopically to determine the nutrition foramina’s quantity, orientation, and direction. Simplecounting was done for the number. The foramina were numbered one millimeter from the boundaries. Every locationof the foramina was seen under a microscope. The stiff wire was employed for obliquity and direction.RESULTS: This cross-sectional investigation included 90 lengthy bones of the upper Limb. The long bones of theupper limbs comprise 80% of a single nourishment foramina. There were two nutritional foramina in 18% of theupper limbs’ long bones. The orientation of nutritional foramina was distal in humeri cases. In the cases of radii andulnae, the orientation was proximal.CONCLUSION: The research has supplied further details on the morphology, topography, and foramina index ofthe nutrient foramina. Given the growing popularity of micro-vascular bone transfer, anatomical data about the longbones of the upper limbs is crucial for doctors.KEYWORDS: Bone cortex, ulnae, radii, humerii, nutrient foramina.

Objective: independent of gestational age, to ascertain the prevalence of iron deficiency anaemia in pregnant women.Study design: a descriptive studyDuration and place of study: From January to Dec 2013, descriptive research was carried out at the MardanMedical Complex’s Gynae-B Unit in Mardan.Material and methods: In 2013, descriptive research was carried out at the Mardan Medical Complex’s Gynae-B Unit in Mardan. All Gynae B Unit pregnant patients, both indoor and outdoor, met the inclusion criteria.Of these expectant patients, 100 with a haemoglobin percentage of less than 10 gm/dl underwent further testing,including a detailed history assessment and questionnaire completion. All pertinent tests for iron deficiency anaemiawere performed, including serum ferritin, Hb electrophoresis, and a complete blood picture. The whole blood picturealso determines anaemias other than iron deficiency. The patient’s iron status is determined by serum ferritin, but thevarious forms of haemoglobin in the blood are identified by haemoglobin electrophoresis. Results: Out of 100 patients,73% had iron deficiency anaemia, 6% had thalassemia, and there were warning signs of hemolytic anaemia andblood loss anaemia from eclampsia, APH, and PET. In one instance, severe iron deficiency anaemia was discoveredto be caused by a malarial parasite.Conclusion: The most common type of anaemia during pregnancy is iron deficiency due to the increased demandfor iron stores from repeated pregnancies.Key Words: Haemoglobin, pre-eclamptic toxaemia, antepartum haemorrhage, total iron binding capacity
A CASE REPORT ON RUPTURED RUDIMENTRY HORN PREGNANCY AT 16 WEEKS WITHOUT THE PAST 2 NORMAL VAGINAL DELIVERIES
Authors: Nuzhat Amin  , Zara  , Samia
Published: June 2024

A unicoronal uterus with a primitive horn, it means that the contralateral side did not fuse properly with the other side,and one of the Mullerian ducts did not fully develop. It is quite uncommon to get pregnant with a noncommunicatingrudimentary horn, and most pregnancies end in rupture in the first or second trimester. It might be challenging to diagnoseprimitive horn pregnancy and its rupture in a woman who has had a vaginal birth in the past. Regular ultrasound scansmay miss it; in most cases, the rupture leads to its discovery. A strong index of suspicion is necessary. We reporteda case of G3P2 with a ruptured rudimentary horn pregnancy at 16 weeks of gestation. The ultrasound incorrectlyidentified the pregnancy as an intrauterine one with fetal demise, and an attempt at termination was made. The patientwas subsequently referred to our hospital when hemoperitoneum and shock were observed, along with a diagnosis ofa ruptured uterus. Upon laparotomy, a rupture of the right rudimentary horn and significant hemoperitoneum werediscovered. An early laparotomy, horn removal, and blood transfusion saved the patient.Study design : A CASE REPORT

Polyparadigmatic approach in teaching philological disciplines in higher education
Authors: Chemezova Ekaterina Rudol'fovna , Dronyakina Nadezhda Vladimirovna
Published: June 2024

This article is devoted to the generalization of theoretical and practical experience in the use of pedagogical technologies in the educational process of the Humanitarian Pedagogical Academy (branch) of the Federal State Educational Institution of Higher Education "V.I. Vernadsky KFU" in Yalta during the 2020-2021, 2021-2022 and 2022-2023 academic years. The study involved 15 teachers and 81 full-time students of the Department of Foreign Philology and Teaching Methods. The subject of research is scientific works on the development of the modern pedagogical paradigm and the search for effective innovative educational technologies in higher education.   This article outlines the main provisions that indicate that modern education recognizes the synthesis of various paradigms in the educational space of the beginning of the XXI century. The special significance lies in the fact that the methodological principle of polyparadigmality does not deny various pedagogical systems and indicates the natural changeability of educational paradigms. The polyparadigmatic nature of modern education does not act as a counterbalance to a specific scientific and pedagogical paradigm, but reflects modern educational practice that meets the needs of modern society. The novelty of the proposed study lies in the fact that the polyparadigm approach previously remained on the margin of pedagogical research.
Reconfigurations of cortical manifold structure during reward-based motor learning

Published: June 2024

Adaptive motor behavior depends on the coordinated activity of multiple neural systems distributed across the brain. While the role of sensorimotor cortex in motor learning has been well established, how higher-order brain systems interact with sensorimotor cortex to guide learning is less well understood. Using functional MRI, we examined human brain activity during a reward-based motor task where subjects learned to shape their hand trajectories through reinforcement feedback. We projected patterns of cortical and striatal functional connectivity onto a low-dimensional manifold space and examined how regions expanded and contracted along the manifold during learning. During early learning, we found that several sensorimotor areas in the dorsal attention network exhibited increased covariance with areas of the salience/ventral attention network and reduced covariance with areas of the default mode network (DMN). During late learning, these effects reversed, with sensorimotor areas now exhibiting increased covariance with DMN areas. However, areas in posteromedial cortex showed the opposite pattern across learning phases, with its connectivity suggesting a role in coordinating activity across different networks over time. Our results establish the neural changes that support reward-based motor learning and identify distinct transitions in the functional coupling of sensorimotor to transmodal cortex when adapting behavior.
Endogenous hydrogen peroxide positively regulates secretion of a gut-derived peptide in neuroendocrine potentiation of the oxidative stress response in C. elegans
Authors: Jia Qi , Young Drew , Sieburth Derek
Published: June 2024

The gut-brain axis mediates bidirectional signaling between the intestine and the nervous system and is critical for organism-wide homeostasis. Here we report the identification of a peptidergic endocrine circuit in which bidirectional signaling between neurons and the intestine potentiates the activation of the antioxidant response in
C. elegans.
We identify a FMRF-amide-like peptide, FLP-2, whose release from the intestine is necessary and sufficient to activate the intestinal oxidative stress response by promoting the release of the antioxidant FLP-1 neuropeptide from neurons. FLP-2 secretion from the intestine is positively regulated by endogenous hydrogen peroxide (H
2
O
2
) produced in the mitochondrial matrix by
sod-3
/superoxide dismutase, and is negatively regulated by
prdx-2
/peroxiredoxin, which depletes H
2
O
2
in both the mitochondria and cytosol. H
2
O
2
promotes FLP-2 secretion through the DAG and calcium-dependent protein kinase C family member
pkc-2
and by the SNAP25 family member
aex-4
in the intestine. Together, our data demonstrate a role for intestinal H
2
O
2
in promoting inter-tissue antioxidant signaling through regulated neuropeptide-like protein exocytosis in a gut-brain axis to activate the oxidative stress response.

Published: June 2024

Osteoporosis, characterized by reduced bone density and strength, increases fracture risk, pain, and limits mobility. Established therapies of Parathyroid hormone (PTH) analogs effectively promote bone formation and reduce fractures in severe osteoporosis, their use is limited by potential adverse effects. In the pursuit of safer osteoporosis treatments, we investigated
R25C
PTH, a PTH variant wherein the native arginine at position 25 is substituted by cysteine. These studies were prompted by our finding of high bone mineral density in a hypoparathyroidism patient with the R25C homozygous mutation, and we explored its effects on PTH type-1 receptor (PTH1R) signaling in cells and bone metabolism in mice. Our findings indicate that
R25C
PTH(1–84) forms dimers both intracellularly and extracellularly, and the synthetic dimeric peptide,
R25C
PTH(1–34), exhibits altered activity in PTH1R-mediated cAMP response. Upon a single injection in mice, dimeric
R25C
PTH(1–34) induced acute calcemic and phosphaturic responses comparable to PTH(1–34). Furthermore, repeated daily injections increased calvarial bone thickness in intact mice and improved trabecular and cortical bone parameters in ovariectomized (OVX) mice, akin to PTH(1–34). The overall results reveal a capacity of a dimeric PTH peptide ligand to activate the PTH1R
in vitro
and
in vivo
as PTH, suggesting a potential path of therapeutic PTH analog development.

Then compare its efficacy as anticancer and antibacterial agents with chemically synthesized ZnO-NPs and the neem leaf extract used for the green synthesis of ZnO-NPs. The TEM, UV-vis, and particle size confirmed that the developed ZnO-NPs are nanoscale. The chemically and greenly synthesized ZnO-NPs showed their optical absorbance at 328 nm and 380 nm, respectively, and were observed as spherical particles with a size of about 85 nm and 62.5 nm, respectively. HPLC and GC-MS were utilized to identify the bioactive components in the neem leaf aqueous extract employed for the eco-friendly production of ZnO-NPs. The HPLC analysis revealed that the aqueous extract of neem leaf contains 19 phenolic component fractions. The GC-MS analysis revealed the existence of 21 bioactive compounds. The antiproliferative effect of green ZnO-NPs was observed at different concentrations (31.25 µg/mL–1000 µg/mL) on Hct 116 and A 549 cancer cells, with an IC50 value of 111 µg/mL for A 549 and 118 µg/mL for Hct 116. On the other hand, the antibacterial activity against gram-positive and gram-negative bacteria was estimated. The antibacterial result showed that the MIC of green synthesized ZnO-NPs against gram-positive and gram-negative bacteria were 5, and 1 µg/mL. Hence, they could be utilized as effective antibacterial and antiproliferative agents.

Plastic pollution is a widespread and growing concern due to its transformation into microplastics (MPs), which can harm organisms and ecosystems. This study, aimed to identify plastic pollution in the feces of terrestrial vertebrates using convenience sampling both inside and outside protected areas in Western Thailand. We hypothesized that MPs are likely to be detectable in the feces of all vertebrate species, primarily in the form of small black fragments. We predicted varying quantities of MPs in the feces of the same species across different protected areas. Furthermore, we expected that factors indicating human presence, landscape characteristics, scat weight, and the MP abundance in water, soils, and sediments would influence the presence of plastics in feces. Among 12 terrestrial species studied, potential MPs were found in 41.11% of 90 samples, totaling 83 pieces across eight species including the Asian elephant (Elephas maximus), Eld’s deer (Rucervus eldii), Dhole (Cuon alpinus), Gaur (Bos gaurus), Sambar deer (Rusa unicolor), Wild boar (Sus scrofa), Northern red muntjac (Muntiacus vaginalis), and Butterfly lizard (Leiolepis belliana). Specifically, 3.61% of all potential MPs (three pieces) were macroplastics, and the remaining 96.39% were considered potential MPs with the abundance of 0.92 ± 1.89 items.scat−1 or 8.69 ± 32.56 items.100 g−1 dw. There was an association between the numbers of feces with and without potential plastics and species (χ2 = 20.88, p = 0.012). Most potential plastics were fibers (95.18%), predominantly black (56.63%) or blue (26.51%), with 74.70% smaller than two millimeters. Although there were no significant associations between species and plastic morphologies, colors, and sizes, the abundance classified by these characteristics varied significantly. FTIR identified 52.38% as natural fibers, 38.10% as synthetic fibers (rayon, polyurethane (PUR), polyethylene terephthalate (PET), polypropylene (PP), and PUR blended with cotton), and 9.52% as fragments of PET and Polyvinyl Chloride (PVC). Human-related factors were linked to the occurrence of potential plastics found in the feces of land-dwelling wildlife. This study enhances the understanding of plastic pollution in tropical protected areas, revealing the widespread of MPs even in small numbers from the areas distant from human settlements. Monitoring plastics in feces offers a non-invasive method for assessing plastic pollution in threatened species, as it allows for easy collection and taxonomic identification without harming live animals. However, stringent measures to assure the quality are necessitated to prevent exogenous MP contamination. These findings underscore the importance of raising awareness about plastic pollution in terrestrial ecosystems, especially regarding plastic products from clothing and plastic materials used in agriculture and irrigation systems.

Combining ability status of the inbred lines is crucial information for hybrid breeding program. Diallel or line × tester mating designs are frequently used to evaluate the combining ability. In the current study a modified diallel model was used, wherein the Griffing’s combining ability effects were further partitioned to understand the effects due to maternal and reciprocal. To do this, eight parental lines of maize were crossed in full diallel method and the generated hybrids along with parents were phenotyped. The field data on the quantitative traits was analyzed using both Griffing’s and the modified model to determine how well the parents’ and the F1 hybrids combined. For each of the traits, a sizable reciprocal and maternal variance was observed. The number of kernel rows per cob variable had a ratio of additive variance to dominance variance greater than one. All other traits including grain yield had a ratio close to zero, suggesting that non-additive gene action was primarily responsible for the genetic control of most of the traits. The narrow sense heritability was low to moderate for majority of the variables, except for number of kernel rows per cob. With the help of the improved model, it was possible to choose superior parents and cross-parent pairings with accuracy. Based on the modified general combining ability effects and maternal effects, the parental line P5 was recognized as a potential female parent and P7 as a good male parent for grain yield and yield-attributing characteristics. The cross combination of P8×P1 had the highest specific combining ability effect on grain yield. P5×P6 cross had the highest reciprocal effect. The correlation analysis implies that the Griffing’s general combining ability effects and specific combining ability effects were found to be less efficient in predicting F1 performance as compared to the modified model.
Mosaico ecológico en la Región Capital: La rehabilitación del Humedal Puente Negro en el paisaje periurbano de la subcuenca de Chacabuco

En los últimos 20 años, la subcuenca de Chacabuco se ha visto transformada por los acelerados procesos de urbanización que se han llevado a cabo en el territorio, modificando el paisaje agrícola de este territorio. La construcción de infraestructuras de movilidad, el relleno de humedales y la proliferación de las parcelas de agrado han consolidado un paisaje periurbano perturbado. Es así, como varios ecosistemas ecológicos se han visto alterados, siendo los humedales, importantes recursos de agua y biodiversidad, los más afectados. Este paisaje periurbano se ha traducido en la consolidación de asentamientos urbanos con una mala calidad de vida y una baja resiliencia frente al cambio climático. La llegada de los proyectos ferroviarios “Santiago - Valparaíso” y “Quinta Normal - Batuco” representan una oportunidad para revertir la situación actual y abordar los desafíos que enfrenta la subcuenca. Sin embargo, para lograrlo es necesario entender los proyectos ferroviarios como el inicio de una estrategia de planificación territorial mayor denominada “Región Capital para Chile” enfocada a conservar y restaurar los ecosistemas ecológicos preexistentes en el territorio.La investigación tiene como objetivo hacer visible, mediante el levantamiento del territorio, la utilización de la teoría del mosaico ecológico de Richard Forman y la representación del paisaje periurbano de Chacabuco, el potencial del corredor ferroviario “Santiago – Valparaíso” y de los humedales como elementos transformadores del paisaje. Cualidad que da pie a una propuesta de masterplan cuyo objetivo es fortalecer la conectividad ecológica y resiliencia del paisaje periurbano, y al diseño de un proyecto de rehabilitación del humedal Puente Negro, explorando distintas estrategias para conservar, integrar y revalorizar los humedales de Chacabuco como ecosistemas de resistencia.
Estudios avanzados del uso de Polimetilhidrosiloxano, Polietileno Tereftalato y factores de agitación y temperatura de secado en el desempeño de placas de yeso

Las placas de yeso son materiales de construcción ampliamente usadas en las edificaciones por su fácil instalación y por las propiedades que aportan en las diferentes zonas donde se instalan. Las placas son fabricadas en base a la reacción de hidratación de sulfato de calcio hemihidrato (HH) a sulfato de calcio dihidrato (DH) que es el corazón endurecido de las placas de yeso. Estudios previos muestran que la incorporación de cualquier aditivo o material a la reacción de hidratación afecta en la morfología de los cristales del dihidrato formado, así como en su porosidad final. Además, la variación del tiempo de agitación durante la reacción, así como el efecto de la temperatura sobre el dihidrato formado tienen efecto sobre las propiedades del material obtenido. Esta investigación tiene dos partes, en la primera se analizó el comportamiento de un aditivo sobre la reacción de hidratación en condiciones similares a las aplicadas durante su fabricación. Un tipo de placa de yeso con propiedades de mayor resistencia a la humedad se obtiene al incorporar un aditivo con repelencia al agua, en este estudio se usa polimetilhidrosiloxano (PMHS). El estudio muestra que la porosidad y los cambios morfológicos que se presentan en los cristales de sulfato de calcio dihidrato con diferentes dosis de polimetilhidrosiloxano, las temperaturas de secado después del fragüe y los diferentes grados de homogeneidad de la mezcla, influyen significativamente en el desempeño de las placas de yeso. En la segunda parte de la investigación se estudia el desempeño de placas de yeso con polimetilhidrosiloxano incorporando residuos de microplásticos de polietileno tereftalato reciclado (PET) de manera de mejorar la resistencia al agua de las placas mediante el reúso de un residuo. Se estudia la variación de tres factores: dosis de polimetilhidrosiloxano (D), tiempo de agitación (H) y temperatura de secado después de fraguado (T). En el proceso experimental, se fabricaron y ensayaron placas de yeso para determinar la absorción de agua, la resistencia a la flexión y la conductividad térmica siguiendo una matriz de diseño experimental. Los resultados obtenidos muestran que incorporando hasta un 10% de microplásticos de polietileno tereftalato reciclado se logran cambios positivos en la absorción de agua y en la conductividad térmica. Además, se estima una disminución de 10% de emisiones de CO2 y un 5% menos de consumo de materias primas (HH, agua y PMHS) al incorporar el PET y principalmente se consume el microplástico lo que disminuye su presencia en el medioambiente. Los cambios morfológicos en los cristales fueron estudiados con las técnicas de microscopia electrónica de barrido (SEM), microanálisis por dispersión de energías de rayos-X (EDX), el programa IMAGEJ y los efectos en la porosidad con la microtomografía computarizada de rayos X (MICRO-CT).
