Holter electrocardiogram (ECG) monitoring is a modern method for diagnosing of the cardiovascular system state and allows for a deeper study of the risks of comorbidity on its part in respiratory diseases. Among a significant number of indicators of the method, heart rate variability stands out as a marker of the balance between the activity of the sympathetic and parasympathetic parts of the autonomic nervous system. In children with acute respiratory diseases, it is important and poorly studied assessment of the autonomic balance and the degree of influence of this pathology on the autonomic functions of the heart. Aim - to analyze the features of heart rhythm variability and its relationship with autonomic innervation in children with acute respiratory diseases. Materials and methods. 50 children (18 children with acute bronchitis, 12 children with pneumonia and 20 clinically healthy individuals of the control group) were examined. The functional state of the cardiovascular system was determined using office blood pressure measurement and Holter ECG monitoring. The ECG was recorded for 5 minutes, followed by an assessment of heart rate variability. Results. The paper analyzes the indicators of heart rate variability, which have a clear physiological basis, such as the measure of the central tendency of the RR interval, indicators of variance, heart rhythm concentration, and the level of parasympathetic effects on the heart rhythm. A significant difference between the data obtained in the experimental groups relative to the control group was established, and a shift in the autonomic balance towards sympathetic tone was revealed, and in children with acute bronchitis these changes are greater than in patients with pneumonia. Conclusions. Assessment of the autonomic nervous system balance using Holter ECG monitoring with a short recording is a modern method for diagnosing its disorders. In respiratory diseases, the most sensitive indicators are heart rhythm concentration, the level of parasympathetic effects on heart rhythm and spectral indicators of heart rate variability. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of the participating institution.

A systematic review of literature in the Embase, MEDLINE, and Cochrane databases reveals incomplete and contradictory data on the psychosocial consequences of short stature in children, including its impact on quality of life (QoL). The aim of this study was to evaluate the effect of recombinant human growth hormone (rhGH) therapy on the QoL of children diagnosed with growth hormone deficiency (GHD). The QoL was considered as an indicator of psychological and social adaptation of the children. Materials and methods. A main group (46 prepubescent children with GHD) was selected and compared to a matched control group (80 healthy children). The group of children with short stature included all children with GHD of the main group and 48 children with idiopathic short stature.The Peds QL4.0 questionnaires for children and parents were used to determine QoL on the scales of “total score”, “physical health”, “psycho-social health”, “emotional functioning”, “social functioning”, and “school functioning”. Statistical processing of the results using the Spearman's correlation coefficient and by estimating the differences between the mean values of two independent variation series by the value of "p" was performed. Results. A more pronounced decrease in QoL was found in children with GHD if they are under 9 years of age compared to their older peers and in children with height SDS<- 3 compared to those with height SDS between -3 and -2. After 12 months of rhGH treatment, the normalization of global QоL score was found to be associated with optimal growth response, as measured by the Peds QL4.0 scale (rs=0.44, p<0.05). The study also revealed a direct correlation between adherence to replacement therapy and QоL (rs=0.28, p<0.05). Furthermore, there was a positive correlation between high compliance with rhGH therapy and optimal growth response (rs=0.85, p<0.05). Conclusions. The study found that there was a difference in the scores of the Peds QL 4.0 children's questionnaire and the Peds QL 4.0 parents' questionnaire in terms of awareness of physical health problems. However, both questionnaires indicated that after 12 months of rhGH therapy, all scales of the Peds QL 4.0 were normalized. Furthermore, a positive correlation was found between the QоL of children with GHD and their optimal growth response to rhGH therapy. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of the participating institution. The informed consent of the patient was obtained for conducting the studies. No conflict of interests was declared by the authors.

Introduction. Introduction period of complementary feeding is very important for the growth and development of the child. Today, alongside the traditional introduction of complementary foods, baby-led weaning (BLW) has become a real trend. This method assumes that the child joins the family table and independently decides what and how much to eat. The BLW method is actively discussed in the scientific literature due to a number of advantages and disadvantages. Aim - to investigate and characterize the peculiarities of the introduction of complementary foods among Ukrainian infants after 6 months of age. Materials and methods. A questionnaire was developed, which contained 3 blocks of questions. A cross-sectional online survey was conducted among 545 women who had children aged 6-7 months to 2-3 years. The results of the study were assessed using the t-Student criterion, Pearson's chi-square test, or Fisher's exact test, conducted with the help of the "XLSTAT" computer program. Differences were considered significant at p<0.05. Results. It was revealed that 40.6% of mothers used BLW complementary food, 22.3% mixed type of complementary food, and 37.0% of respondents used traditional spoon feeding. Children who received BLW were born full-term (95.9%) and to a greater extent through spontaneous delivery (70.9%). Among the groups with different methods of complementary feeding, no significant difference was observed due to manifestations of atopy. It was determined that the child's independent decision of how much to eat (64.7%) and what to eat (52.9%) was more common in the group of interviewed mothers who used the BLW method compared to the groups using mixed and traditional feeding. The consistency of food at the beginning of complementary feeding corresponded to the method of feeding. Among the adverse events in the BLW group, shortness of breath from food entering the respiratory tract (11.8%, p=0.043) and to a lesser extent vomiting (28.4%, p=0.012) were observed more often compared to children on traditional complementary foods. Conclusions. The data we obtained indicate the growing popularity of BLW among Ukrainian mothers and good awareness of mothers in the correct use of this method, and negative phenomena were observed no more than in similar surveys described in the scientific literature. The research was carried out in accordance with the principles of the Declaration of Helsinki. Informed consent of the child and child's parents was obtained for the research.

The role of ACE1 I/D gene polymorphism in predicting the severity of COVID-19 (coronavirus infection) in children with autoimmune diseases, including juvenile idiopathic arthritis (JIA), is an important aspect for determining the tactics of personalised therapy. Aim - to study the features of the clinical course of COVID-19 and allelic polymorphism of the ACE1 gene in JIA to predict the severity of coronavirus infection. Materials and methods. The course of COVID-19 was retrospectively analysed in 44 patients with JIA and 20 children without chronic somatic pathology (control group). Genomic DNA preparations were isolated and purified, which made up the Patient Biobank for genotyping at rs4646994 of the ACE1 gene. Results. In the majority (70.0%) of children with JIA, COVID-19 infection has a mild, subclinical course. Insufficient medication control of JIA activity may be a predicted risk factor for more severe COVID-19. The severity of COVID-19 is not a risk factor for exacerbation of autoimmune disease. In the study of the distribution of ACE I/D genotypes and alleles in children with JIA depending on the severity of COVID-19, no significant difference in the groups was obtained. The DD genotype was significantly more common in the group of children with mild COVID-19 without rheumatological pathology and there was a tendency to increase the frequency of the genotype (II insertion) among patients with JIA who had mild COVID-19 compared with the control group. Conclusions. In the mild course of COVID-19 in patients with JIA, the DI genotype at the ACE1 rs4646994 gene was significantly more frequent and there is a tendency to increase the frequency of the genotype (II insertion). Such genotypes in patients with JIA may lead to an imbalance of the components of the renin-angiotensin system, but, on the other hand, they can be considered as protective, due to which the group of children with JIA does not develop severe COVID-19. The research was carried out in accordance with the principles of the Declaration of Helsinki. The study protocol was approved by the Local Ethics Committees of the institutions indicated in the work. Informed consent of the child and child's parents was obtained for the research.

The use of antibiotics can affect the resistance of the intestinal microflora, causing digestive disorders and antibiotic-associated diarrhea (AAD). The drug "Neoflorum", which contains Lactobacillus rhamnosus and Saccharomyces boulardii, is a promising combined probiotic for maintaining the health of the intestinal microflora. The aim of the study is to investigate the effectiveness of the probiotic "Neoflorum" in the prevention of AAD and the safety of the use in children, who are receiving antibiotics because of acute respiratory infection (ARI). Materials and methods. An open, prospective, non-interventional, comparative study was conducted. 47 children aged 3-13 were examined (average age 6.91±2.87 years). The main group of the study included 25 children who received an antibiotic and a combined probiotic "Neoflorum" in the complex treatment of an ARI. 22 children of control group received an antibiotic without a probiotic. Results. At the beginning of the study, none of the patients in both groups complained of dyspeptic disorders. Analysis of coprological studies and the level of fecal calprotectin in both groups at the initial stage of treatment did not reveal any pathological changes. AAD developed in 20% of children in the intervention group and 45.5% of children in the control group, which was 2.3 times less. The level of fecal calprotectin was normal in almost all children with AAD (except one child of the control group) on the first day of the diarrhea. 92% of children in the main group noted good tolerance of "Neoflorum", and two children - satisfactory tolerance. There were no side effects while taking "Neoflorum". Conclusions. In the case of conducting oral antibacterial therapy against the background of the use of the probiotic Neoflorum AAD from the first day of treatment, AAD was detected 2.3 times less often than when conducting antibiotic therapy without the background intake of a probiotic. The use of the Neoflorum probiotic from the first day of antibiotic therapy made it possible to achieve a statistically significant antidiarrheal effect already on the 4-5th day, as indicated by a significantly lower number of children with AAD in the main group - 16% compared to the control group - 45.5%. Good tolerance of "Neoflorum" is noted by 92% of patients. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of the clinical base. The informed consent of the patient was obtained for conducting the studies.

Numerous studies have demonstrated the effectiveness of intravenous infusion of lidocaine for postoperative analgesia in abdominal surgery among adult patients. However, this approach is rarely used among pediatric patients. Aim - to conduct a comparative evaluation of various methods of postoperative analgesia and their effects on the dynamics of pain intensity indicators and the cumulative daily dose of morphine in pediatric patients after various types of surgical interventions. Materials and methods. We examined 150 children who underwent trauma (I group, n=40), abdominal (II group, n=48), and urological (III group, n=62) surgical interventions. Each group was divided into two subgroups. Children received intravenous lidocaine as a component of multimodal analgesia in the perioperative period in subgroups Ib (n=17), IIb (n=19), and IIIb (n=24). Children were not prescribed lidocaine in control groups Ia (n=23), IIa (n=29), and IIIa (n=38). To assess the intensity of postoperative pain, a numerical rating scale (NRS) was used. Statistical processing of the obtained data was carried out using the SPSS 21 statistical information processing package (©SPSS Inc.). Results. The results of our study show that the intensity of pain was significantly lower in the early period of observation (from 3 to 9 hours) and the intermediate period (24 hours) of the postoperative period, but not in the late period of observation (48 hours and more). The impact of systemic administration of lidocaine on the reduction of pain at rest after trauma surgical interventions has not been determined. Postoperative systemic use of lidocaine in children reduced the average cumulative daily dose of morphine during the 1st day after all types of surgical interventions. Conclusions. This study demonstrated the efficacy of intravenous infusion of lidocaine in the treatment of postoperative pain syndrome in pediatric patients. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of all participating institutions.

The aim of the study is to assess the effectiveness of the neuroprotection complex in intrauterine herpesvirus infection. Materials and methods. To test the effectiveness of the developed neuroprotection complex (erythropoietin, early use of sensory integration techniques), 60 children with intrauterine herpesvirus infection, who were classified as high-risk for significant central nervous system disorders, were examined from birth to 1 year of age: the main group was 30 newborns who were additionally treated with a new complex of neuroprotection, and the comparison group - 30 children, whose medical support was carried out in accordance with the protocols of the Ministry of Health of Ukraine. The obtained data were processed by the methods of variational statistics accepted in medicine, using the Student's t-test for numerical indicators and Fisher's angular transformation for indicators represented by frequencies, with a critical significance level of p<0.05. The results. According to the static and motor development of children at the age of 12 months by the Denver scale, the vast majority of children (70.0%) of the comparison group were delayed in development by 2-4 months, while in the main group only 6 (20.0%) remained slight delay of 1-2 months. Accordingly, the assessment of psychomotor development according to the Griffiths scale was significantly reduced relative to the main group (112.7±7.6 points vs. 156.4±7.1 points, respectively). There were no cases of infant death in the examined children. Perinatal disorders of the central nervous system led to the disability of 2 (6.7%) children of the comparison group. Side effects or complications of the proposed therapy were not observed. Conclusion. The use of a complex of therapeutic and preventive measures aimed at neuroprotection in newborns with intrauterine infection with herpesviruses (prediction of the risk of central nervous system disorders at birth, in children at high risk - early neuroprotective treatment with low doses of recombinant erythropoietin and early use of sensory-motor integration) allows to improve neurocognitive and psychomotor abilities of children up to 1 year of age. The effectiveness of the neuroprotective complex was 80.0%. The research was carried out in accordance with the principles of the Declaration of Helsinki. The research protocol was approved by the Local Ethics Committee of the specified institution. Informed consent of the children's parents was obtained for the research.

Always Ascending (But Sometimes Descending)
Authors: Markowitz Fran , Avieli Nir
Published: July 2024

This research explores the African Hebrew Israelite Community (AHIC)’s ongoing bond with the Land of Israel which they see as part of their program for a divinely inspired Edenic lifestyle. Based on long-term ethnographic engagements, our research focuses on community members’ use of a discursive trope that we call ‘ascending-descending’. This terminology, we argue, is both flexible and failure-proof, as it allows the AHIC to present themselves as Edenic and agrarian as well as modern, while also explaining their unsuccessful attempts at living off the land as the result of human fallibility. We also note an ongoing commitment within Hebrew Israelite theology to God’s plan that they believe can never fail, as well as to promises of earthly salvation and eternal life that continue to compel members of the AHIC to seek new and yet unrevealed paths to the Garden of Eden.
Conservationist Cowboys in the Climate Age
Authors: Taylor Sarah McFarland
Published: July 2024

This article argues that the hit Western television series, Yellowstone (2018–), offers an instructive case study as to how storied media can effectively use culturally resonant, religiously inflected idiom to cross the membrane of the digital filter bubble, morally engaging polarized publics. The series’ popular appeal bridges regional, political, and religious divides in ways that cultural creations explicitly labeled and presented as ‘environmental media’ fall short. Taking up thorny environmental and agricultural land-management issues, Yellowstone effectively presents more liberal-leaning viewers with the complexities, pressures, and ethical challenges faced by multigenerational ranchers in the American West, while making rural communities feel more ‘seen’ and appreciated. In a deeply divided country, Yellowstone, as a cultural work—and now as a broader popular cultural phenomenon worldwide—demonstrates the powerful potential of storied media to cultivate common ground in the climate age.

Published: July 2024

The prediction of permeability in porous media is a critical aspect in various scientific and engineering applications. This paper presents a machine learning (ML) model based on the XGBoost algorithm for predicting the permeability of porous media using microstructure characteristics. The seahorse optimization algorithm was employed to fine-tune the hyperparameters of the XGBoost algorithm, resulting in a model with predictive solid capabilities. Regression analysis and residual errors indicated that the model achieved good prediction results on the training and testing datasets, with RMSE values of 0.0494 and 0.0826, respectively. A SHAP value sensitivity analysis revealed that the essential inputs were the size of the inclusions, with the quantiles representing the maximum size of the inclusions being the most significant variables affecting permeability. The findings of this study have important implications for the design and optimization of porous media, and the XGBoost algorithm-based ML model provides a fast and accurate tool for predicting the permeability of porous media based on microstructure characteristics.

Research background. Mango peel is a production waste and can cause environmental problems, but its nutritional value consists of bioactive compounds that could be beneficial for human health. The aim of this study is to determine the bioactive compounds, antioxidant and anti-inflammatory activities of mango peels and their use in muffins.
Experimental approach. The content of polyphenols, carotenoids and total phenols as well as the antioxidant activity of mango peel extract were evaluated. The anti-inflammatory activity of the extract was investigated using Caco-2 cell assay. The mango peel powder was then incorporated into muffin formulations. The sensory properties of these fortified muffins were evaluated. The total phenolic content, antioxidant activity and anti-inflammatory properties of the muffin extracts and their bioaccessible fractions were also analysed.
Results and conclusions. The mango peel contained quercetin, phenolic compounds, α-carotene, β-carotene and lutein, which have antioxidant potential. In Caco-2 cells exposed to induced inflammation, the mango peel powder extract (γ=10, 50 and 100 μg/mL) attenuated the production of reactive oxygen species (ROS), tumour necrosis factor-alpha (TNF-α) and interleukin-8 (IL-8), while maintaining cell viability. Muffins supplemented with 5 % mango peel powder showed good sensory properties, but not as good as those of plain muffins without mango peel powder. The total phenolic content and antioxidant activities in both the extract and the bioaccessible fraction of the supplemented muffins were higher than those observed in the standard muffins. Moreover, the extract and bioaccessible fraction of the supplemented muffins resulted in a higher reduction of ROS, IL-8 and TNF-α production in Caco-2 cells than those obtained from the standard muffins.
Novelty and scientific contribution. This study is the first to investigate the protective
effects of mango peel and muffins supplemented with mango peel powder against IL-1β-induced oxidative damage in Caco-2 cells. The results confirm that both mango peel and the supplemented muffins inhibited the production of inflammatory markers, including ROS and cytokines. These findings suggest that mango peel could be a valuable component of functional food formulations including dietary supplements.

New biodegradable packaging has been developed from renewable sources, mainly of vegetable origin. Arrowroot starch has been recently used to produce high-quality biodegradable films capable of behaving well when incorporating oils, extracts, metal, and metal nanocomposites. The study aimed to verify the impact of incorporating metals in the sulfate and chloride forms in a biopolymeric matrix from arrowroot starch in terms of biodegradability, physicochemical and microbiological parameters. Different arrowroot films were produced to incorporate solutions with a concentration of 1 Mol L-1 of sulfate and chloride metals. The action of biodegradability in soil, UV transmittance, and visible light were observed in UV-Vis spectrophotometry and antimicrobial action on Escherichia coli, Staphylococcus aureus, Salmonella serovar Typhimurium, and Salmonella serovar Enteritidis. Good results were obtained, such as biodegradability time between 81.70 to 100 % (30 days), a low transmission rate of UV radiation and visible light between 250 to 890 nm, high capacity for bacterial inhibition between 22.08 to 10.05 mm for E. coli, among 25.59 to 11.10 mm for S. aureus, between 22.14 to 11.66 mm for S. serovar Typhimurium and between 21.11 to 8.26 mm for S. serovar Enteritidis. It is concluded that the biodegradable films of arrowroot starch incorporated with metals showed potential in all the evaluated tests, thus characterizing possible new products for different uses, such as low time available in the environment, preservation of the characteristics of special products, and antimicrobial capacity.
La filosofía como una continuación por medio de la tarea educativa
Authors: Alarcón Leiva Jorge
Published: July 2024

The article addresses the current state of the Philosophy of Education, which seeks to understandthe nature and foundations of education to improve its effectiveness. It identifies a significant gapbetween the theoretical and practical problems of education, as they are perceived and responded to on the public agenda. This separation limits the explanatory capacity of the discipline and reducesits relevance for educational actors. Given this panorama, the article proposes to explore how to integrate educational theory and practice. The methodology of the article involves a critical analysisof Wittgenstein’s point of view, enriched with the perspectives of Williams and Medina. It examineshow these philosophers address the relationship between philosophical theory and educationalpractice, especially in terms of how beliefs and instructional processes are interrelated and can beunderstood from an integrated perspective. The main results suggest that integrating philosophicaltheory with educational practice allows not only a deeper understanding of the foundations ofeducation, but also an improvement in the effectiveness of educational strategies. In addition, finalconsiderations are raised about the current state of philosophical research in education, highlightingthe importance of continuing to explore these connections to move towards a more comprehensiveand practical approach in the Philosophy of Education.
Character education based on the value sand norms of the Indonesian philosophical system
Authors: Rustan Effendi Yulius
Published: July 2024

The purpose of this article is to elucidate how the principles of nationalism influence students' attitudes and behaviors, shaped by the norms and values of Pancasila, a philosophical system. The methodology employed for data collection involves a systematic review (meta-synthesis) of digital sources, encompassing an analysis of meta-ethnographic studies. The meta-ethnographic model serves as an "interpretive" tool, facilitating a comprehensive exploration of pivotal studies and their connection to the concept of character education in nationalism within the Pancasila framework. In order to delve into the realm of interpretive studies, there is a need to acquire "iterative" (spiral) data, deconstructing the ontological, epistemological, and axiological dimensions of the Pancasila philosophy. Employing this interpretive approach, the author chronicles the progress in the implementation of character education focused on nurturing students' sense of nationalism. This approach is rooted in the values and appreciation of the norms encapsulated in Pancasila, which, up until now, have not been fully optimized within the school context. Furthermore, the authors expand upon the foundational study, meticulously analyzing the concept of Pancasila within an intricate web of philosophical interpretations. This intricate analysis aims to decipher the essence of existence that students should embrace in their lives.
Desarrollo de habilidades socioemocionalesen la formación de educadores en la sociedad actual
Authors: Calderón Calderón Antonio
Published: July 2024

Socio-emotional skills comprise a set of habits, thoughts, and emotions that facilitate interpersonal relationships through the appropriate expression of emotions and consideration oftheir impact on others. Backed by neurology, these skills are crucial for learning and for educators’contributions to new generations. This essay aims to reflect on the socio-emotional skills of future education professionals, exploring their influence on teaching and their contribution to society. Given the pandemic situation, it is proposed to present the role of socio-emotional education in theuniversity curricular activities of teacher trainers in Chile, using the critical-interpretative method and hermeneutic phenomenology. The discussion is based on experience, dialogue with groups of students and teachers, identifying key points for the inclusion of emotional skills in teachertraining. The process involved the active participation of the teacher, who took on the initial role inthe intervention by providing instructions and guidelines for the development of socio-emotional skills related to ethics and education in various contexts. This was carried out virtually at a higher education institution in Chile. The conclusion emphasizes the urgency and need to integrate socioemotionaleducation into the curriculum for university education professionals. The alignmentbetween Goleman, Bisquerra, and Morin, theorists who have delved into the subject, is highlighted,although the persistence of orthodox educational models that exclude emotions, focusingexcessively on intellectual capacities and overlooking the need for comprehensive emotionaltraining to face contemporary societal challenges, is noted.

Published: July 2024

The research incorporates the experiences of a group of artisans from Azuay and Cañar in Ecuador, aims to reflect on the professional practices of artisan collectives and their relationshipwith formal educational processes from a pedagogical approach focused on social and popular education. The study applies qualitative methodology with ethnographic focus. The results not only highlight that the spaces occupied by craftsmanship in the social imaginary are markedby obstacles and restrictions in professional practice, but also demonstrate that the knowledge they possess is conditioned by ethnic and sociocultural dimensions. Despite having experiencesand knowledge that are not far from the curriculum taught in the educational system, these are excluded and considered of lesser value. The research concludes that recognizing artisanal methods and procedures can be used as powerful formative elements to strengthen identity, democraticparticipation, dialogue of knowledge, social justice, and true intercultural education. Consequently, social and popular education can help promote the active participation of artisans and other collectives and contribute to the transformation and change of unequal structures from a socioeducationalperspective.

Treatment of industrial effluents of recalcitrant nature using ozone, hydrogen peroxide and ultraviolet radiation
Authors: Rodriguez Tatiana , Botelho Diego , Cleto Eduardo
Published: July 2024

Currently diverse industries have high pollution potential because their productive processes generate great volumes of refractory effluents. These effluents are problematic, mainly due to the presence of recalcitrant compounds that are detrimental in wastewater treatment plants using biological systems in their processes. In general, biological treatments do not remove refractory elements. Also, in most cases these compounds can inhibit the yield or are toxic for biota responsible to remove the polluting agents. The Advanced Oxidative Processes (AOPs) represent a technological alternative with a great potential for treatment of no biodegradable effluents. In this paper a review of the use of advanced oxidatives processes: Ozone (O3 ), peroxide of hydrogen (H2 O2 ) and ultraviolet radiation (UV) is presented applied to the treatment of recalcitrant effluents.

Published: July 2024

Profiles of water temperature, dissolved oxygen, pH, electrical conductivity and the salinity were measured in the swamp El Eneal municipality of San Onofre, Sucre, following a nictemeral design between May/2003 and April/2004. It was found that the system is completely mixed from the thermal point of view due to the action of the wind, in combination with the morphology and its location near the coastal line. It was also found that this coastal swamp is oligohalin, nevertheless most of the time the system can be considered as a limnetic system. During prolonged droughts, the salinity reached its maximum value of 3.4 ppm, which could become a limited factor for communities of strictly limnetics organisms.

Computer simulation of long bone development: A model of endochondral ossification
Authors: Garzón Diego Alexander , García José Manuel , Doblaré Manuel
Published: July 2024

Some bones of the body are constituted by cartilaginous supports in which growth is produced both with the ossification process that extends from the center of the bone towards its borders in a process so called endocondral ossification. In this period of bone tissue morphogenesis the factors controlling the process are mainly biochemical, and the mechanical influence is much lower. This paper presents a simulation model using reaction-diffusion equations for the growth and ossification process in the prenatal bone. It is primarily controlled by an interactive inhibitor-activator loop associated with the parathyroid hormone (PTHrP) and the Indian Hedgehog (Ihh). These equations in combination with the simulation of the proliferative process and the cartilage cell growth (chondrogenesis) lead to a quite accurate simulation of the growth process of a long bone, even predicting the development of secondary ossification centers in the epiphysis.

Published: July 2024

In this paper the effects of the radiated electromagnetic interferences produced by some wireless communication devices on medical equipments that monitor or support a patient’s life are presented. First, it was measured the electric field level produced by four cellular phones and one walkie-talkie at different distances from the devices. Afterwards, it was evaluated the behavior of 16 medical equipments when they were exposed to the electric fields measured previously. The results showed that a significant number of the medical equipments tested presented some functional alteration with different levels of severity. Likewise, it was found that some medical equipments were interfered at electric field values below immunity test levels established by the international standard IEC 60601-1-2.
Exergy diagnosis of the combustion process in a Diesel engine

Published: July 2024

In this work a single-zone and two-species exergy diagnosis model is developed and applied for characterizing the operation of a diesel engine from a secondlaw standpoint. The model allows to study the in-cylinder process during the closed-valve period, and to determine how the exergy is distributed and what is the exergy potential of the losses. Experiments were carried out in a test bed equipped with an automotive, direct injection, turbocharged diesel engine operating at several loads. Combustion diagnosis was made from instantaneous in-cylinder pressure signal and the main operation parameters of the engine were measured in order to guarantee steady state. Irreversibilities and exergy distribution throughout the process were determined. It was found that combustion is the main source of irreversibilities. Results show that exergy destruction decreases as load increases, which mainly led to an increase in the exergy of exhaust gases. Additionally, the cogeneration potential of the engine was identified, exhibiting significant differences between first and second-law results.
Parametric analysis of the ionic concentrations effects in the behavior of the sinoatrial node
Authors: Sierra Daniel Alfonso , Rueda Oscar Leonel , Correa Carlos Rodrigo
Published: July 2024

A sensibility study on the effect of ionic concentrations in the behavior of the sinoatrial node was carried out. The study was based on the model proposed by H. Zhang, A. V. Holden and M.R. Boyett. It was simplified using concepts of experimental design. The study was developed on a set of eight characteristics that describe the action potential generated by the sinoatrial node, for both the central and peripheral cells. The sensibility analysis shows that the sodium and potassium ionic concentrations should be controlled to maintain the normal behavior of the node. On the other hand, the simulated changes in calcium concentrations do not produce significant effects on the node operation. Finally, a response surface model was developed as a simplification of the original model. This response surfaces simplified model may be used in the on-line estimation of the operation characteristics of the in vitro sinoatrial node. From the computational point of view, and using the simplification strategy described above, the processing model time was decreased as a 1 to 50 ratio.

Published: July 2024

In Brazil, as in many other countries significant advances have been verified in intensive clonal silviculture with remarkable differences on parameters of growth and development between species clones and hybrids of Eucalyptus. At the same time, during recent years the concept of multiple uses of tree logs to increase the yield of the forest enterprise as cellulose and paper and solid wood has been introduced. The present paper studies the wood uniformity index and radial variability of density using x-rays densitometry of 8 year clones Eucalyptus grandis and E. grandis x urophylla in order to optimize their use. This experiment was performent at Suzano Cellulose and Paper Company Clone Plantation in San Miguel de Arcanjo-SP-Brazil. The best five clones of the species and hybrid by their silviculture characteristics were selected. Three models of radial density variation were found and the formation of three different types of wood were characterized (youthful, of transition and adult); the average value of wood apparent density in clones was 0.46 and 0.54 g/cm3 for Eucalyptus grandis and E. grandis x urophylla, respectively.
