Teachers performance evaluation: the experience of the Dentist Academic Program of the Universidad del Valle.
Authors: Villavicencio Judy Elena 
Published: July 2024

Background: Teaching activity evaluation as a result of students’ opinion is a process that has been developing in the Dentist Academic Program for approximately ten years. This kind of evaluation has its formal origin in American and European universities during the 1920´s. Objective: To analyze the results of the teacher’s performance trends according to the inquiries undertaken by the Dentist Academic Program students of the Universidad del Valle from 2005 to 2007, and to determine if there are significant differences in the teacher’s evaluation results according to academic ranks and program formation areas. Method: A descriptive transversal study was carried out, with teaching evaluation questionnaires undertaken by students of the Dentist Academic Program of the Universidad del Valle during 2005 and 2007. Results: A total of 474 teachers were evaluated. The average results during the five semesters evaluated for the teachers were 4.4. It was found that in four of the five semesters analyzed do exist significant differences in the results of the evaluation by the students at the level of teachers’ academic ranks. Additionally, there were no significant differences in the results of the students’ evaluation for the Academic Program Areas.
Exercise induced hemolysis: relation between the activity of glucose-6-phosphate dehydrogenase and the magnitude of the hemolysis.
Authors: Bonilla Javier Fernando , Palomino Fernando 
Published: July 2024

Introduction: Oxidation and hemolysis associated with physical exercise, moderate and severe, have been studied by several investigations, but only in the most recent have been evaluated how the variations of the genetic determined mechanisms for antioxidative enzymatic erytrocytic capacity, contribute to establish different levels of susceptibility to the hemolysis induced trough exercise, however, those studies have mainly been made on non sedentary subjects with deficiency of enzyme G6PD. Purpose: The objective of this study was to establish if there is either yes or not a relationship between the activity level of erythrocytic activity of the enzyme G6PD and the hemolysis grade, induced by exercise in adult healthy sedentary men and after an experimental bout of moderate exercise pre-exhaustive and equivalent in modality and intensity. Methods: Twenty five men, sedentary and seemingly healthy, were evaluated after an exercise session of 1 hour over a cycloergometer, with 70% of VO2peak previously founded. On the basis of plasmatic Hb, the proportion of hemolysis and haptoglobin consumed, taking in account the variation of plasma haptoglobin and intravascular hemolysis after and at least three hours post-exercise, were calculated. Results: The experimental subjects presented laboratory evidence (free plasma hemoglobin, percentage of hemolysis and haptoglobin) of intravascular hemolysis immediately after and at least past three hours of exercise bouts. Conclusion: The grade of hemolysis had an inversely significative correlation with the G6PD activity and, this intensity had a significative different behaviour below the percentil 40 media founded for G6PD and above of it. Thus, the oxidative hemolytic response in sedentary and healthy individuals who had lower levels G6PD activity with one bout of exercise with 70% of VO2peak was highly variable.

Authors: Guevara Hellen Astrid , Luengas Pilar Ester , Garavito Giovanny 
Published: July 2024

Introduction: The group of natural products has gained much interest in recent years because of the popular belief that they are effective and more secure than synthetic medications, or because of recent health tendencies seeking to supplement nutrition. Objective: To describe the group of natural products from a sanitary authority point of view. Methodology: Observational, descriptive, cross-sectional study from the universe of Drug approvals of Natural Products presented by a database from the Instituto Nacional de Vigilancia de Medicamentos y Alimentos (Colombian Sanitary Authority). Results: Nearly half of the natural products legally accepted for marketing are herbal medicines and the other half are dietary supplements, along with specific-use products. The vegetable species with the greatest number of commercialization authorizations is artichoke Cynara scolymus (alcachofa), followed by calendula (Calendula officinalis), valerian (Valeriana officinalis), garlic (Allium sativum), and ginkgo (Ginkgo biloba). Foreign species predominate in the fabrication of commercialized herbal medicines. A novel classification is proposed of the plant organ or drug employed in the production with which it is evident that leaves are used more with respect to any other plant organ. Capsules, tablets, and solutions are the predominant pharmaceutical forms. Conclusions: The group of natural products has demonstrated growing evolution in drug approvals in these last years; for the herbal medicines subgroup, national production predominates even though there is a minimum use of native species; while for dietary supplements and specific use products subgroups importation is predominant, evidencing the necessity for national policies to articulate the norms with Colombian needs and to stimulate the valorisation and sustainable use of our natural resources with adequate profit for the communities that will be reflected in greater national production using resources in which Colombia has competitive advantages.
Physical education teacher skills in preparing HOTS lesson plans and their contribution to teaching performance
Authors: Hardiansyah Sefri , Blegur Jusuf 
Published: July 2024

Background: Higher-order thinking skills (HOTS) are 21st-century thinking skills needed by students to survive the demands of the current era. However, the problem is that teachers often do not optimally include HOTS in the lesson plan and the implementation of learning. Research Objective: This study aimed to investigate the relationship between the teacher's skill in preparing HOTS lesson plans and the teacher's performance in applying them to physical education. Methods: This type of research is correlational using two research variables: the teacher's skills in preparing HOTS lesson plans and teaching performance. The participants were 28 physical education teachers (men = 21, women = 7) who participated in the Teacher Professional Education Programme at Universitas Negeri Padang in 2022. The HOTS lesson plan data and teacher teaching videos were taken from the documented performance test results (PDF files and teaching videos). Data analysis used regression with the help of SPSS version 25. Findings/Results: The results showed that α < 0.05 (0.007) with a regression value of 2.923 means that the teacher's skills in preparing HOTS lesson plans are positively determined by their performance in teaching HOTS to students. The contribution made by the teacher's ability to prepare HOTS lesson plans to teacher teaching performance is 24.70%. Conclusion: Teachers who can prepare a good HOTS lesson plan can provide a guarantee for their HOTS teaching performance. Thus, the more detailed the teacher formulates the goals, objectives, activities, media, and HOTS assessments, the more it helps them determine their teaching performance that encourages their students' HOTS.

В работе исследованы вопросы изобретательской деятельности одного из талантливых представителей российского инженерного сообщества конца ХIХ–начала ХХ вв. Ипполита Владимировича Романова, которая была связана с созданием первых в нашей стране электрических транспортных средств. В Петербурге при непосредственном участии известного инженера и предпринимателя П.А. Фрезе были построены двухместные электромобили системы Романова, а также электрический омнибус. В самом начале ХХ в. русские инженеры развивали идеи городского электрического транспорта – трамваев, электромобилей и омнибусов, для массового производства которых требовалась государственная поддержка. В 1900 г. И.В. Романовым был получен патент в России, а в 1905 г. аналогичный патент в Соединенных Штатах Америки на подвесную железную дорогу, именовавшуюся дорогой «системы инженера Романова». В Гатчине прошли успешные испытания монорельсовой дороги на электротяге, построенной по проекту Романова.

With the direct participation of the famous engineer P. Freze, two-seater Romanov electric vehicles and an electric omnibus were built in Peterburg. At the very beginning of the twentieth century, Russian engineers developed the idea of urban electric transport – trams, electric vehicles and omnibuses, for the mass production of which required state support. In 1900 I. Romanov received a patent in Russia, and in 1905 a similar patent in the United States of America for the suspended railway, called the road «systems of engineer Romanov». In Gatchina were successfully tested monorail electric built under the project Romanova.

Decomposition of the Unitary Representation of $SL_{2}(\mathbb{R})$ on the Upper Half Plane into Irreducible Components
Authors: Alabbad Fatimah 
Published: July 2024

The main purpose of the paper is to find the inversion formula for the covariant transform. This formula is equivalent to the decomposition of the unitary representation of $SL_{2}(\mathbb{R})$ on the upper half plane into irreducible components. We consider an eigenvalue $1+s^{2}$ of the Casimir operator: $$d\rho_{k}(C)=-4v^{2}\left(\partial_{u}^{2}+\partial_{v}^{2}\right),\quad \text{where}\, k=0.$$
To find the inversion formula, first we study the representation of $SL_{2}(\mathbb{R})$, $\rho_{k}$ and $\rho_{\tau}$, induced from the complex characters of $K$ and $N$ respectively. Then, we find the induced covariant transform $\mathcal{W}_{\varphi_{0}}^{\rho_{k}}$ with $N$-eigenvector to obtain a transform in the space $\FSpace{L}{2}(SL_{2}(\mathbb{R}/N)$. Thereafter, we compute the contravariant transform with $K$-eigenvector $$\mathcal{M}_{\phi_{0}}^{\rho_{\tau}}:\FSpace{L}{2}(SL_{2}(\mathbb{R})/N)\rightarrow \FSpace{L}{2}(SL_{2}(\mathbb{R})/K).$$
Some Properties of (M,k)-quasi Paranormal Operators on Hilbert Spaces
Authors: Rexhëbeqaj Hamiti Valdete , Makolli Shkumbin 
Published: July 2024

Let H be a complex Hilbert space and let T represent a bounded linear operator on H. In this paper we introduce, a new class of non-normal operators, the (M,k)-quasi paranormal operator. An operator T is said to be (M,k)-quasi paranormal operator, for a non-negative integer k and a real positive number M, if it satisfies:
||Tk+1x||2 < M ||Tk+2x|| ||Tkx||, for every x in H.
This new class of operators is a generalization of some of the non-normal operators, such as the k-quasi paranormal and M-paranormal operators. We prove the basic properties, the structural and spectral properties and also the matrix representation of this new class of operators.

Authors: Mas'ud Ryan Ali , Junta Zeniarja  
Published: July 2024

Breast cancer is a disease commonly suffered by women worldwide, ranking as the second-largest disease burden. In response to the urgent need for improved detection accuracy, Convolutional Neural Networks (CNNs) promise significant advancements. The objective of this research is to optimize the use of CNNs with the DenseNet architecture for breast cancer detection. The study employs quantitative methods, leveraging Deep Learning through CNNs. Mammography data is sourced from Kaggle, specifically the “Breast Histopathology Images” dataset. This dataset comprises 90,000 digital mammography images, which are preprocessed and divided proportionally for training, validation, and model testing. Research variables encompass CNN model parameters, training techniques, and the integration of imaging modalities to enhance breast cancer detection performance. The research focuses on processed mammography data, with accuracy and image quality as key evaluation metrics for breast cancer sample identification. Our findings demonstrate that the DenseNet architecture within CNNs achieves an impressive 92% accuracy in breast cancer detection. This remarkable performance signifies success in enhancing image quality and class prediction, aligning with the DenseNet architecture’s flow diagram. Ultimately, these results contribute significantly to effective breast cancer diagnosis by optimizing CNNs with the DenseNet architecture to improve image quality during breast cancer sampling.

Published: July 2024

AbstractUnique characteristics of the naked mole-rat (NMR) have made it increasingly popular as a laboratory animal model. These rodents are used to study many fields of research including longevity and aging, cancer, circadian rhythm, pain, and metabolism. Currently, the analgesic dosing regimens used in the NMR mirror those used in other rodent species. However, there is no pharmacokinetic (PK) data supporting the use of injectable analgesics in the NMR. Therefore, we conducted 2 independent PK studies to evaluate 2 commonly used analgesics in the NMR: meloxicam (2 mg/kg SC) and buprenorphine (0.1 mg/kg SC). In each study, blood was collected at 8 time points after subcutaneous injection of meloxicam or buprenorphine (0 [predose], 0.25, 0.5, 1, 2, 4, 8, and 24 h). Three NMRs were used per time point for a total of 24 animals per PK study. Plasma concentrations of meloxicam were highest between 0.5 and 1 h postinjection. Levels remained above the extrapolated dog and cat therapeutic threshold levels (390 to 911 ng/mL) for at least 24 h. Plasma concentrations of buprenorphine were highest between 0.25 and 0.5 h postinjection. Levels remained above the human therapeutic threshold (1 ng/mL) for up to 21 h. No skin reactions were seen in association with injection of either drug. In summary, these data support dosing meloxicam (2 mg/kg SC) once every 24 h and buprenorphine (0.1 mg/kg SC) once every 8 to 12 h in the NMR. Further studies should be performed to evaluate the clinical efficacy of these drugs by correlating plasma concentrations with postoperative pain assessments.
TENDÊNCIA DA PRECIPITAÇÃO E SEU APROVEITAMENTO PARA FINS NÃO POTÁVEIS NA AMAZÔNIA OCIDENTAL, ACRE
Authors: Delgado Rafael Coll , Souza Leonardo Paula de 
Published: July 2024

Foi estudado a tendência climática anual da precipitação e seu aproveitamento para fins não potáveis em região da Amazônia Ocidental brasileira. Utilizaram-se dados pluviométricos compreendidos entre o período de 1960 a 2013, para sua captação considerou-se as áreas de telhados das edificações prediais da Universidade Federal do Acre – Campus Floresta (CF), localizado no município de Cruzeiro do Sul/AC. Calcularam-se as precipitações médias mensais e suas respectivas probabilidades de ocorrência de 75%, 85% e 95%. Foi detectada leve tendência positiva dos dados pluviométricos ao aplicar o teste de Mann-Kendall. O teste de Pettitt não foi significativo para esta série de precipitação. Foi verificada redução significativa para a estação chuvosa amazônica. A estação seca teve uma redução do seu período mais seco, o que tudo indica uma mudança no comportamento e na sazonalidade da precipitação na região. Aproveitar mensalmente as precipitações é suficiente para manter de 96,45% a 70,89% da demanda hídrica do CF. Os excedentes hídricos proporcionados pela precipitação média, probabilidade de 75% e 85% garantem a manutenção anual do CF, para a probabilidade de ocorrência de 95% é necessário a complementação a partir do mês de agosto até meados de novembro a dezembro. Palavra-chave: análise estatística, água não potável, população urbana e rural PRECIPITATION TREND AND ITS NON-POTABLE USES IN THE WESTERN AMAZON ACRE ABSTRACT This paper analyses the annual climate trend of precipitation and its non-potable use in a university campus in the Brazilian Western Amazon. We used pluviometric data gathered between 1960 and 2013, and, for the harnessing of water, we considered the roof of buildings in the Federal University of Acre – Campus Floresta, located in Cruzeiro do Sul, Acre. We calculated the monthly average of precipitation and the probability of its occurrence: 75%, 85% and 95%. We detected a slightly positive tendency in the pluviometric data when applying the Mann-Kendall test. We also applied the Pettitt test, however, it did not provide meaningful results for this series of precipitation. We verified a meaningful reduction in precipitation during the rainy season in the Amazon. The dry season showed a reduction in the length of its driest period, which indicates a change in the patterns and seasonality of precipitation in the region. Using the monthly rainfall can secure between 96.45% and 70.89% of the Campus water demand. The water surplus propitiated by the average precipitation thus probably guarantees between 75% and 85% of the water needs in Floresta Campus. Securing 95% of the demand requires complementation from August through to November or even December. Keywords: statistical analysis, non-potable water, urban and rural population.
