Authors: Mashtakov V. A. , Kondashov A. A. , Bobrinev E. V. , Shavyrina T. A. , Udavtsova E. Yu.
Published: August 2022

Introduction. Studies of risks dynamics of death and injury of the Federal Fire-Fighting Service personnel in the performance of official duties for a long period (from 2006 to 2021) have shown that difficulties often arise due to the heterogeneity of data, their significant fluctuations in different periods of time and the influence of random factors.

Problem Statement. In this paper, to study the risks of death and injury of personnel of the Federal Fire-Fighting Service of the State Fire Service in the performance of official duties, time series smoothing methods (the moving average method and the exponential smoothing method) were used, which made it possible to eliminate abnormal observations and reduce the influence of random factors.

Theoretical Part. To identify trends in the risks of death and injury of personnel of the Federal Fire-Fighting Service of the State Fire Service in the performance of official duties, the method of time series smoothing was used. The methods of moving average and exponential smoothing are considered. The distribution of the risks of injury and death of the personnel of the Federal Fire-Fighting Service of the State Fire Service in the performance of official duties for the period 2006-2021 is shown, the average annual levels of injury and death risks for this period are determined, the dynamics of the ratio of the number of cases of injury and death in these years is considered.

Conclusions. The number of registered cases of injuries has decreased due to the improvement of the occupational safety management system. During the period from 2006 to 2021, there was a reduction in the risk of injury to personnel by 4 times. The ratio of the number of injured and dead has significantly decreased (by more than three times) — from 31.5 to 9.4. In addition, as a result of occupational safety management system improvement, the number of injuries with severe and moderate damage has decreased due to their transition to the category of injuries with light damage.

Authors: Garton Paul , Wawrzynski Matthew , Wawrzynski Matthew R. , Lemon Jacob , Naik Sapna
Published: August 2022

Student engagement is a widely researched and utilized concept to enhance student experiences and outcomes. Most research on student engagement, however, focuses on curricular engagement with relatively little emphasis placed on the co-curriculum. This study utilizes Case’s theory of relational engagement to analyse findings from three focus groups conducted at a university in South Africa to better understand how relational engagement is instantiated in the co curriculum and how the co-curriculum differs from the standard academic curriculum in terms of engagement. In particular, we show relational engagement is just as important in the co-curriculum, highlighting student relations to broader university life, to fellow students, and to communities beyond the campus.

An Exploratory Qualitative Study on the Perceived Barriers to Accessing Ghanaian University Counselling Services
Authors: Ocansey Sylvia , Sefotho Maximus
Published: August 2022

Despite research emphasis on university students’ counselling needs and service benefits, barriers to counselling service participation for students have been less explored in Ghanaian higher education. Yet literature is replete with reports on high undergraduate student attrition and a low sense of belonging, stressing the severe need for increased counselling service participation among students in higher education. This article explored the barriers to increased counselling service participation faced by Ghanaian public university students. Our research engaged 13 counselled undergraduate students, purposively selected via snowball and convenience sampling techniques. We engaged study participants in in-depth interviews and a focus group discussion to gather appropriate data and further used the interpretive phenomenological approach to find meaning in the gathered data. Students revealed their perceptions on poor counsellors’ sense of initiative, their low service awareness, and their misconceptions which seem to hinder students’ counselling service participation. Our results underscore the need for more service advertising and possibly increased counsellor initiative to promote counselling service use among higher education students in Ghana. Daily service advertising with counsellors’ reliance on text and WhatsApp messaging, still pictures and short videos on the various campuses (Amos et al., 2020) would considerably increase students’ awareness of counselling services.

Published: August 2022

O professor deve possuir conhecimentos e habilidades variadas para assumir a tarefa educativa diante da abrangência e da complexidade da Educação. O presente estudo reporta resultados de um programa de intervenção nos processos autorregulatórios de estudantes de Licenciatura, o qual teve como objetivo avaliar se a intervenção contribuiu para ampliar o conhecimento dos estudantes acerca do conceito de autorregulação da aprendizagem; melhorar suas percepções sobre si, como estudantes e como futuros professores; e aumentar a intenção de seguir a carreira docente. Adotou-se como referencial teórico a Teoria Social Cognitiva. A amostra foi composta por cinquenta estudantes de três turmas do terceiro semestre de diferentes cursos de Licenciatura. Os participantes foram divididos aleatoriamente em Grupo Experimental I e II e Grupo Controle. Os dados, coletados por questões conceituais e autorreflexivas, foram examinados por análise de conteúdo. Resultados revelaram que os estudantes dos grupos experimentais demonstraram compreender melhor o conceito de autorregulação da aprendizagem após a intervenção, quando comparados aos do grupo controle. Os resultados foram mais modestos em relação a ter melhores percepções sobre si, como estudantes e como futuros professores. Ademais, a intervenção não influenciou no desejo dos estudantes de seguir a carreira docente. Destaca-se também a importância dos resultados para a discussão sobre a eficácia dos programas de intervenção na formação de professores.

O grupo de Berlim produziu interpretações específicas sobre a constituição humana, o estudo, a atividade e seus componentes, bem como sobre o papel do sujeito da atividade. A extensão dos estudos experimentais em território alemão representou uma importante contribuição para a edificação da Teoria da Atividade de Estudo, seja por seu potencial de continuidade, seja pelas interpretações realizadas.
Proceso para la remociónde CO₂, de las emisiones de generadores de energía utilizando un covertidor catalítico y la microalga Scenedesmus dimorphus
Authors:   , Arroyo Gómez Citlalli Adelaida
Published: August 2022

In this research, a process composed of a catalytic converter and three airlift photobioreactors conected in sequence containing the microalga Scenedesmus dimorphus was estudied to remove CO₂, CO and NOx emissions from a steam generating boiler that uses diesel as fuel. The effects of shear rate, light intensity, and light/dark cycles on microalga growth were also evaluated. Finally, different gas flow rates were evaluated on the volumetric mass transfer coefficient (KLa) of O₂ and CO₂. In this study, the catalytic converter, transformed a maximum of 78% of CO to CO₂ and 89.8% of NO to NO₂ present in the flue gas. Within the experiments carried out in the airlift reactors, it was oberved that at low shear rates (Re≈3200), a high biomass productivitiy of 0.29 g L-1 d-1 was obtained. However, when cultivating the microalga with a light intensity of 60.75 μmol m-₂ s-1 and a light/dark cycle of 16/8 h, the máximum values of productivity and CO₂ fixation rate were obtained, which were 0.44 g L-¹ d-¹ and 0.8 gCO₂ L-¹ d-¹, respectively. The máximum CO₂ removal efficiency was 52.14%. The máximum O₂ and CO₂ KLa values were 3.71 and 3.45 h-¹, respectively. From these experiments, the hydrodinamic and kinetic parameters were determined, which were used in the development of a mathematical model that allowed predicting the growth of the microalgae in a semi-continuous culture inside an Airlift reactor, involving the mass transfer of CO2, the rate of formation of HCO₃- ion, the carrying capacity (máximum biomass concentration that can carry without a negative effect) of the microalga and oxigen production. The proposed mathematical model reproduced the biomass values in an airlif reactor. It also predicted that microalga has a greater preference for consuming carbon in the form of CO₂ and that there was no accumulation of oxygen such that it could inhibit microalga growth.
Consistency of morphological dictionary MorfFlex
Authors: Hlaváčová Jaroslava , Mikulová Marie , Štěpánková Barbora
Published: August 2022

Language corpora usually contain, in addition to their own texts, various types of annotations. The most common one is a morphological annotation, which consists in assigning a lemma and a morphological tag to each wordform. For morphological tagging, morphological dictionaries are traditionally used. Our paper presents a new version of the so-called “Prague” morphological dictionary MorfFlex used for tagging many Czech corpora (particularly Prague Dependency Treebanks, corpora published by the Institute of the Czech National Corpus in Prague or large Czech web corpora of the Aranea series). Three basic principles were used to update the dictionary: the Golden Rule of Morphology, the Principle of Paradigm Unity, and the Principle of Paradigm Uniqueness.
Identifying Errors in Russian Web Corpora
Authors: Khokhlova Maria
Published: August 2022

The explosion of the Web leads to the production of large amounts of texts and inevitably influences their quality. Errors that tend to occur more often can distort results, especially when texts are used for scientific purposes, in language teaching or learning. Hence, there is a need to examine the existing corpora based on web texts and to clean up the data, which may contain such “noisy” fragments. In our study, we deal with the problem of errors and analyze the Aranea Russicum Maximum corpus. Among such errors, we can name, above all, encoding errors, incorrect font types, as well as segments written in other languages. These phenomena result in incorrect morphological analysis and lemmatization, frequency distortion, as well as the fact that lexical units cannot be found and therefore displayed to corpus users. The paper focuses on the errors, describes their types and outlines possible ways to eliminate them.
A Project Work as a Way of Bringing Corpora to Secondary School
Authors: Kogan Marina , Zakharov Victor
Published: August 2022

Corpus linguistics is one of the most dynamic and rapidly developing areas of modern linguistics. It affects all areas of linguistics, including methodology of teaching foreign languages, translation and other linguistic disciplines. Corpus linguistics has had a direct impact on teaching foreign languages. However, in general, it remains a marginal method in teaching. Analysis of publications on the subject allows us to conclude that very few studies are long-term and aimed at working with schoolchildren. This article proposes a model for the development of sustainable interest among high school students in online corpora as sources of linguistic information, including the initiation stage in the form of project work in mini-groups to study well-known sayings with the consequent stage aiming at completing tasks supplementing the main textbook on a regular basis. The organization of project work addressing the corps of 11th grade students of the Natural Science Lyceum at Peter the Great St. Petersburg Polytechnic University is described. The paper outlines further research.

Authors: Groza E. , Gicevskis K. , Linkevics O. , Kiene S.
Published: August 2022

The paper presents the results of the research, which was initiated in our previous publication. The main goal of the research is to develop and validate our own multi-objective simulation tool for determination of optimal mix and sizing of off-grid and grid-connected microgrid systems. The first version of the developed model was tailored specifically for simulation of household off-grid system, which consisted of solar photovoltaics (PV), micro wind turbine, electric batteries, and backup power generator. Proposed algorithms are based on simulation of mentioned resources and hourly electric loads of off-grid system with the objective to reduce unsupplied energy volumes and total system costs. Several alternatives were considered with different configurations of the off-grid system and dispatching strategies of available resources. The developed model was validated with calculations of real off-grid system and results were compared to those, which were made in the previous publication, using Homer Pro software.
Energy Transport in SiO2 Crystals: Luminescence Excitation Spectra of Stishovite and α-Quartz
Authors: Trukhin A. N.
Published: August 2022

The migration of elementary electronic excitations was studied in a single crystal of stishovite and compared with migration in a crystal of α-quartz and polycrystalline stishovite powder. The research method is based on comparing the transfer of absorbed energy to luminescence centers, used as detectors of quasiparticles, and the near-surface nonradiative annihilation of electronic excitations. A sign of migration is the appearance of some minima in the photoluminescence (PLE) excitation spectrum in the region of maxima in the intrinsic absorption spectrum. The PLE spectrum of stishovite contains the first minimum at 9.8 eV, indicating the migration of electronic excitations and the existence of an intrinsic absorption band in stishovite at 9.8 eV. In α-quartz, the first minimum in the PLE spectrum is located at 10.5 eV and corresponds well to the intrinsic absorption band of the exciton.
Analysis of Remotely Piloted Aircraft Payload for Oil Spill Detection
Authors: Zavtkevics V. , Urbaha M.
Published: August 2022

Operational monitoring of large sea aquatorium areas with the aim of detecting and controlling oil pollution is now carried out using various technological systems, such as satellite remote sensing, sea-going vessels, various aircraft and remotely piloted aircraft (RPA). Currently, the use of RPA for the fulfilment of monitoring tasks in the aquatorium is being intensively developed and can eliminate problems of remote sensing performed by satellites and piloted aircraft, such as short presence in the monitoring area, very long delay of information (up to 48 hours) and low quality of imagery. This paper presents mathematical modelling of RPA multi-sensor pay-loads for oil spill detection, monitoring and control. Information obtained from payload sensors is critical for increasing effectiveness of detection and monitoring of oil spills. Nowadays, many types of sensors are used for oil spill detection and monitoring. The most common sensors for detection of oil pollution are optical, multispectral, hyperspectral, thermal and laser fluorometers. Some oil pollution detection sensors have limitations, such as false alarm, only daytime operation, weather restrictions. Airborne remote sensors cannot provide all information required for detection of and response to oil spills, and water quality monitoring in the spill area. A model for selecting sensors for multi sensor payload that will make it possible to optimize the application of RPA for oil spill detection was developed. The RPA payload can be increased/reduced to the greatest possible extent with the help of different types of equipment at various parameters. The mathematical model of the integrated payload considers detection capability of sensors, weather conditions, sensor characteristics, and false alarm rate. The optimal multi-sensor payload will optimize the application of RPA for oil spill detection and monitoring.

Published: August 2022

Throughout the centuries, Riga has been the city with dynamic development. Its territory has unceasingly expanded, whereby previously unused territories have been urbanized. Managers of the city understood already at the end of 19th century that unified geodetic network had great importance in the development of the city. Since then, Riga’s local geodetic network has evolved with the city, several coordinate and height systems have been replaced, but the task has remained the same – to provide a flawless, homogeneous geodetic foundation for various surveying activities. In 2018, the development of the local geodetic network in several parts of the city was completed, whereby the problem arose – altitude values of surveyed terrain points determined by using the improved geodetic network did not coincide with altitude values determined using the GNSS method. Considering the above-mentioned problem, the objectives of this study were set: to plan and carry out control measurements of the improved local geodetic network in the vicinity of Grizinkalns, to provide analysis of the obtained results and recommendations for further development of a local geodetic network. The difference between the heights determined by the geometric levelling method and the heights determined by the GNSS method shall not exceed 2 mm. According to the GNSS method, using the quasi-geoid model LV’14 v2, the determined heights of the geodetic grid points differ from the given ones by 0.062 m on average. The differences are systematic. To overcome these differences, the quasi-geoid model needs to be refined.

The purpose of the study. To clarify the possibilities of using radiation research methods in the framework of complex diagnostics of local peritonitis for timely recognition and treatment of intra-abdominal abscesses and infiltrates.

Materials and methods. The analysis of the results of a complex radiation examination in 61 patients with local peritonitis of various etiologies who were treated at the N.V. Sklifosovsky Research Institute for Emergency Medicine was carried out. The complex of radiation diagnostics included ultrasound and X-ray examinations, computed tomography (CT). The studies were performed both initially at admission and in dynamics.

Results. The diagnostic algorithm for local peritonitis is analyzed, three stages are identified with the determination of the method of choice on each of them. Ultrasound and X-ray examination methods are mainly used at the stage of primary diagnostics and for dynamic control. CT allows you to clarify the type, localization and volume of inflammatory changes, their relationship with the surrounding organs and structures. When analyzing the results of radiation diagnostics, it was determined the need to identify and evaluate the main signs of local peritonitis, both direct: the presence of voluminous formation of inflammatory genesis (infiltrate and/or abscess); and indirect: changes in the source organ of peritonitis; changes in structures adjacent to the infiltrate /abscess; the presence of reactive effusion into the thoracic and abdominal cavities.

Conclusion. Comprehensive radiation diagnostics for local peritonitis makes it possible to obtain complete information about the nature of both inflammatory changes in local peritonitis and the causes of them. The obtained data of complex diagnostics help the surgeon to choose a rational treatment strategy for these patients, including minimally invasive. Diagnostic monitoring allows you to evaluate the effectiveness of treatment and carry out timely correction of tactics.
Lysergic Acid Diethylamide Produces Anxiogenic Effects in the Rat Light/Dark Test and Elevated Plus Maze
Authors: Conway Catherine N. , Baker Lisa E.
Published: August 2022

Recent clinical trials indicate favorable therapeutic outcomes of psychedelic-assisted psychotherapy for anxiety and treatment-resistant depression. Whereas the neurobiological systems underlying these effects are not well understood, animal behavioral models can serve to investigate these mechanisms. For the current study, we implemented 2 rodent models predictive of anxiolytic drug effects, a light/dark test and an elevated plus maze (EPM), to investigate the acute and subchronic effects of LSD, respectively. Forty-eight, adult male Sprague-Dawley rats were randomly assigned to receive LSD (0.00, 0.02, 0.04, 0.08 mg/kg) and assessed in the light/dark test 15 min after the first injection. Five additional injections were given, once every 48 hours, after which rats were assessed in the EPM either 48 (n = 24) or 72 hours (n = 24) after the last injection. A dose-dependent and statistically significant decrease was observed in number of entries into, F(3, 44) = 12.79, p < .001,η2 = .47, and time spent, F(3, 48) = 14.15, p < .001, ηp2 = .47, in the brightly lit compartment. In the EPM, closed arm entries, F(1, 17) = 28.85, p < .001, ηp2 =.36, and time spent in closed arms, F(1, 17) = 20.14, p < .001, ηp2=.99, were significantly higher compared to entries or time in open arms by rats assessed 48 hours after the last LSD injection, but not by rats tested 72 hours after the last injection. These findings indicate that acute and subchronic LSD treatment produce transient anxiogenic effects. In consideration of positive therapeutic outcomes of psychedelic-assisted psychotherapy, alternative preclinical models may be warranted to discern the mechanisms underlying the putative therapeutic effects of serotonergic hallucinogens.

La epidemia de viruela de 1782-1783 y sus efectos sobre la mortalidad en Santafé, virreinato de Nueva Granada
Authors: Bejarano Rodríguez Cristhian Fabián
Published: August 2022

La epidemia que asoló a Santafé -Bogotá- y sus cuatro parroquias entre diciembre de 1782 y marzo de 1783 tuvo grandes impactos en términos demográficos. Por ello, desde la perspectiva de la historia demográfica, exploramos el impacto directo que esta epidemia tuvo sobre la mortalidad de la ciudad. Las curvas de mortalidad construidas con base en los registros parroquiales permiten analizar la mortalidad mensual registrada durante 1782 y 1783 en dos grupos de edad: adultos y párvulos. Con ayuda del método conocido como 'factor multiplicador' se logró calcular la intensidad diferencial de la epidemia por grupos de edad y por género y calidad en adultos.
Pojęcie dostawcy usług społeczeństwa informacyjnego w świetle Dyrektywy Parlamentu Europejskiego i Rady (UE) 2019/790
Authors: Pązik Adam
Published: August 2022

Opracowanie omawia jeden z problemów związanych z prawem wydawców prasy przewidzianym przez normy Dyrektywy 2019/790, a mianowicie zagadnienie interpretacji pojęcia „dostawcy usług społeczeństwa informacyjnego”. Analiza prowadzi do wniosku, że pojęcie to powinno być rozumiane w sposób szeroki i obejmować także podmioty niewynagradzane przez odbiorców świadczonych przez nich usług, lecz finansujące swoją działalność z innych źródeł, jak również podmioty, które z tytułu korzystania z publikacji prasowej osiągają znikome przychody lub nie osiągają ich w ogóle.
Retoryka tańca w aplikacji TikTok
Authors: Kotowski Bartłomiej
Published: August 2022

Aplikacja internetowa TikTok cieszy się globalną popularnością. Formy tańca tiktokerów, tworzone i eksponowane w cyberprzestrzeni, składają się z różnych kompilacji i umożliwiają aczasową i aprzestrzenną komunikację pomiędzy użytkownikami na całym świecie. Taniec w subświecie sieci tiktokerów ma wymiar międzykulturowy. Celem działań w aplikacji TikTok jest pozyskanie potwierdzenia społecznego, kreacja wizerunku czy zakup konkretnego produktu. Kontynuowanie, re-kreowanie ekspozycji w aplikacji jest oznaką poddania się perswazji przez kolejnych uczestników, w tym implementujących konkretny trend czy viral. Analiza przeprowadzona na poziomie semantycznym, syntaktycznym i pragmatycznym potwierdza tezę, że forma tańca tiktokerów tworzona i eksponowana za pomocą aplikacji TT w mediach społecznościowych ma charakter fragmentaryczny, a jej internetowe egzemplifikacje są wykorzystywane w celach perswazyjnych (marketingowych, politycznych, kreowanej autoprezentacji) i służą wypełnieniu określonego celu, implementują poglądy, informacje, służą transmisji treści. Kolejne części pracy opierają się na podziale semiotyki wprowadzonym przez Charlesa W. Morrisa (Morris 1938).

Authors: Vidal Pinilla Gehovell J. , Vidal Pinilla Yanlika A.
Published: August 2022

El objetivo del presente artículo es develar los aprendizajes sobre economía circular a partir de dos experiencias investigativas en comunidades rurales de los municipios Cajibío y Popayán en el departamento del Cauca. Para dicho propósito se recurrió a la triangulación de la información a partir del análisis de fuentes secundarias e información de fuentes primarias obtenida por medio de la aplicación de encuestas, grupos focales, inmersiones en contexto. Finalmente se realizó análisis de contraste de los resultados obtenidos con la teoría encontrada que sustenta los principios de economía circular. Los resultados propenden a la generación de aprendizajes sobre economía circular derivados de las prácticas comunitarias en aprovechamiento de residuos de los hogares rurales que pueden orientarse hacia la valorización de los beneficios con el fin de dejar atrás el modelo económico lineal tradicionalmente percibido para resaltar el uso de dichos residuos como recursos contribuyendo a reducir los niveles de contaminación e incrementar las opciones de generación de ingresos en las comunidades rurales objeto de estudio.
Monte Carlo Sensitivities and Performance of Woven Deployable Entry Systems
Authors: Raghunandan Pratibha , Stern Eric , Haskins Justin
Published: August 2022

A material response model is developed for the determination of erosion rates and thermal response of woven materials to enable accurate thermal protection material sizing and future missions to Venus and giant planets. The stagnation-point thermal response is evaluated using the model developed in Icarus, a material response finite volume solver. A Monte Carlo global sensitivity analysis is further performed using a stand-alone Python wrapper script developed to determine the interactions between key parameters in the material surface energy balance of the one-dimensional simulation, such as the convective blowing correction parameter and weave material properties. The time-accurate material response for the dual-weave erosion and surface temperatures show good agreement with stagnation flat face arcjet tests involving time-varying aeroheating–cooling cycles. The high-fidelity Monte Carlo sensitivity analysis technique was used to address challenges in thermal protection sizing for the Adaptive Deployable Entry and Placement Technology (ADEPT) system, a low ballistic coefficient hypersonic decelerator. The results provide new correlations for such weaves involving carbon–air equilibrium oxidation and wall enthalpy imposition through a B-prime formalism. Through the multivariate regression analyses and uncertainty rankings performed, only two properties were found to largely contribute to the transient thermal response of the gore, with emissivity contributing up to [Formula: see text] of the total output uncertainty at the front face and [Formula: see text] at the back face.

Objectives:

Liver disease is a serious public health problem. There are many causes of liver disease and the liver is a vital organ in the body, so when it is damaged, its function can be affected. Cochlospermum tinctorium is a plant commonly used by Central African populations to relieve liver-related ailments such as jaundice and hepatitis. This study aimed to assess the hepatoprotective activity of aqueous leafy stem extract of C. tinctorium against liver injury induced by subacute exposure of rats to carbon tetrachloride (CCl4).

Material and Methods:

Thirty rats were distributed into six groups including control (H2O), healthy control (H2O), positive control (silymarin 25 mg/kg), extract control (aqueous leafy stem extract 50 mg/kg), and tests (aqueous leafy stem extract 50 or 25 mg/kg). Liver injury was induced by CCl4 (0.5 mL/kg) on the 4th and 11th days of the treatment. Rats were sacrificed on the 15th day, aspartate aminotransferase, alanine aminotransferase (ALT), gamma-glutamyltransferase (γ-GT) activity, and serum levels of total bilirubin, creatinine, and tissue oxidative stress markers (malondialdehyde, glutathione, catalase, and superoxide dismutase) were evaluated. Histological examinations of the liver and kidney were performed. A phytochemical study of C. tinctorium aqueous leafy stem extract was done.

Results:

This study showed that C. tinctorium aqueous leafy stem extract (50 or 25 mg/kg) significantly reduced (P < 0.01) ALT (94.79 ± 14.99 U/L) and γ-GT (10.08 ± 5.40 U/L) activity, and decreased the serum total bilirubin level compared to control. The aqueous leafy stem extract significantly diminished (P < 0.01) tissue MDA level (2.67 ± 0.05 µmol/mg protein), increased glutathione level (347.08 ± 10.81 nmol/mg protein), catalase (131.03 ± 6.99 µmol/ min/mg protein), and SOD activity (86.0 ±1.50 U/mg). Liver microphotography showed hepatic parenchyma with almost no leukocyte infiltration in the portal and perisinusoidal spaces, and an important reduction of cell necrosis following treatment with the aqueous leafy stem extract compared to the control.

Conclusion:

These results demonstrate that the hepatoprotective activity of the aqueous leafy stem extract of C. tinctorium may be due to its antioxidant and anti-inflammatory properties and may, therefore, justify the use of this plant as a candidate for complementary study to proceed with the development of medicine against liver diseases.

Remote delivery approaches to laboratory courses in the response to the COVID-19 pandemic have included a spectrum spanning passive options such as providing students with prerecorded videos of experiments to replacing in-person laboratory experiences with immersive virtual reality environments. While interactive activities that require students to make choices about experimental design or procedure, mimicking levels of inquiry present in in-person laboratory experiments are preferred, creating custom activities of this type often require expensive equipment, a media production team, and knowledge of multiple programming languages. The open source, non-linear storytelling platform, Twine, provides a free alternative that allows instructors to create custom interactive choose-your-own-adventure activities based on their existing laboratory curriculum and inclusive of text, images, and video clips. We used Twine to create a choose-your-own-adventure laboratory activity as the final experiment in a remote delivery format organic chemistry laboratory course that allowed students to obtain customized data based on their experimental choices. We expanded this work to create an entire course of Twine choose-your-own-adventure laboratory activities for a third term organic chemistry laboratory course.
TEACHING RIGID BODY EQUILIBRIUM: FROM THE STATICS TEXTBOOK TO THE PRACTICAL CLASSROOM EXPERIENCES
Authors: Cardona Montoya Diana Lorena , Álvarez Vargas César Augusto
Published: August 2022

The study of equilibrium of rigid bodies is a fundamental subject in the fundamentals and design of structural systems in engineering. This process is taught in a general way with the elaboration of a Free Body Diagram and the application of equilibrium vectorial equations for moments and forces. The process of teaching and learning typically takes end when the student finds a solution that fulfills the equilibrium equations but without any engineering conclusions. The proposed method presented in this paper states that students first solve the theoretical problem as it is typically done but complementing its solution using a set of common machine elements and video-editing software tools to compare the solution given by theory with real solutions given by the mounting of calibrated experiments. The final result allows the student to describe conclusions about important differences between theory and practice generated by friction, assembly processes, thermal changes among other kinds of non-controllable perturbations that are considered as negligible in theory.
