The adsorption of carbon monoxide on the TiO2 (anatase) surface at room temperature was studied by infrared spectroscopy and volumetry. The experimental data obtained indicate weak adsorption of CO molecules on the exponentially heterogeneous surface. The adsorption heat decreases according to the logarithmic law in the coverage range of 0.002-0.03. The extinction coefficient of adsorbed CO for the heterogeneous CO/TiO2 system is calculated using the Bouguer-Lambert-Beer law with correction for the Lorenz field taken into account. The conditions for the applicability of the Bouguer-Lambert-Beer's law for the study of heterogeneous systems are discussed.

Authors: Sidhartha G
Published: September 2021

Abstract: In recent times, we have realized the importance of vital signs such as Oxygen saturation and heart rate i.e beats per minute (BPM) due to the covid-19 situation worldwide. SpO2 and BPM are being used as preliminary indicators for testing a person’s health, the drop in the oxygen saturation is perceived as one of the symptoms of a person suffering from coronavirus. Oximeters are portable devices that are used to measure the SpO2 and BPM of a person. Timely measurements of oxygen saturation can aid in taking preventive measures. This paper discusses the construction and development of an IoT-based pulse oximeter that is capable of transmitting the reading obtained to any remote location wirelessly. The proposed system uses Arduino as the microcontroller which is used for signal processing and Esp-01 as the Wifi platform to enable remote data transmission. The data is communicated remotely through Blynk mobile application. This project is aimed at reducing the manual effort undergone in regularly updating the oxygen saturation to the doctor, in the case of a person undergoing home treatment. Though an oximeter is not a screening te st, it is a primary indicator of a person’s health. Keywords: Heart rate, SpO2, IoT, Arduino, BLYNK server, Red, IR.
A Comparative Study of Alzheimer Detection Techniques
Authors: Patil Adwait
Published: September 2021

Abstract: Alzheimer’s disease is one of the neurodegenerative disorders. It initially starts with innocuous symptoms but gradually becomes severe. This disease is so dangerous because there is no treatment, the disease is detected but typically at a later stage. So it is important to detect Alzheimer at an early stage to counter the disease and for a probable recovery for the patient. There are various approaches currently used to detect symptoms of Alzheimer’s disease (AD) at an early stage. The fuzzy system approach is not widely used as it heavily depends on expert knowledge but is quite efficient in detecting AD as it provides a mathematical foundation for interpreting the human cognitive processes. Another more accurate and widely accepted approach is the machine learning detection of AD stages which uses machine learning algorithms like Support Vector Machines (SVMs) , Decision Tree , Random Forests to detect the stage depending on the data provided. The final approach is the Deep Learning approach using multi-modal data that combines image , genetic data and patient data using deep models and then uses the concatenated data to detect the AD stage more efficiently; this method is obscure as it requires huge volumes of data. This paper elaborates on all the three approaches and provides a comparative study about them and which method is more efficient for AD detection.

Abstract: In today's world, nearly everything we have a tendency to do has been simplified by machine-driven tasks. In a trial to specialize in the road whereas driving, drivers usually miss out on signs on the facet of the road, that can be dangerous for them and for the folks around them. This drawback may be avoided if there was AN economical thanks to inform the motive force while not having them to shift their focus. Traffic Sign Detection and Recognition (TSDR) plays a vital role here by detection and recognizing a symptom, therefore notifying the motive force of any coming signs. This not solely ensures road safety, however additionally permits the motive force to be at very little a lot of ease whereas driving on tough or new roads. Another normally long-faced drawback isn't having the ability to know the which means of the sign. With the assistance of this Advanced Driver help Systems (ADAS) application, drivers can not face the matter of understanding what the sign says. during this paper, we have a tendency to propose a way for Traffic Sign Detection and Recognition exploitation image process for the detection of a symptom and a Convolutional Neural Networks (CNN) for the popularity of the sign.

Eliciting Idiom Retention through Alliteration in a Classroom Activity
Authors: Wahyuningtyas Dwi
Published: September 2021

Alliteration comes up as one of the efforts that follow the notion of linguistic motivation in creating language retention and memorization to learners. Idiom is one of the language phenomena where alliteration takes place as part of its non-arbitrariness principle. The claim underlying the effectiveness of alliteration in aiding language retention in idiom is tried to be applied in some classroom activities which may consist of pre, whilst, and post-teaching. All the activities in the teaching session are arranged to be integrated with idiom learning using alliteration. Learners' ability to recall idioms containing aliteration will also be tested in the provided exercises. The success of the expected retention on learners will be measured from the result gained from the activity divided simply into three phases, pre-teaching, whilst-teaching, and post-teaching where it will be conducted for approximately 90 minutes. As some deviations possibly made can influence the result, the teacher should figure out some considerations affecting the effectiveness of the lesson given. Reflection phase should be conducted maximally, so that learners’ response is really fruitful that it can be known whether they are engaged with the activity and gain the material well. In the first activity, they work semi-independently, so that the assessment is expected to be more objective, covering the combination of group and individual work.

Published: September 2021

Robots have infiltrated many aspects of human life up to this point, and with the term Industry 4.0, robots have even become the primary workforce in various factories. This condition necessitates that the robots collaborate without clashing. This paper discusses the application of two arm robot manipulators working alternately in sorting agricultural products. The proposed method employs simple image processing to detect the object and becomes the input to the system to control the robots. The effectiveness of the proposed method is enhanced by the application of a Fuzzy Logic Controller to smoothen robots’ joints motions. The average time required by the robot to finish their task from detecting to returning to standby position is 11.76 s for green tomatoes and 12.86 s for red tomatoes. The experimental results show that the proposed method is effective in controlling two robots to pick and place agricultural products using visual servoing.

Published: September 2021

Sensor data acquisition is used to obtain sensor data from IoT devices that already provide the required sensor data. To acquire sensor data, we can use Bluetooth Low Energy (BLE) protocol. This data acquisition aims to process further data which will later be sent to the server. Bluetooth Low Energy (BLE) has an architecture consisting of sensors, gateways, and data centers, but with this architecture, there are several weaknesses, namely the failure when sending data to the data center due to not being connected to internet network and data redundancy at the time of data delivery is done. The proposed solution to solve this problem is to create a system that can acquire sensor data using the Bluetooth Low Energy (BLE) protocol with use a store and forward mechanism and checking data redundancy. The proposed system will be implemented using sensors from IoT devices, the gateway used is Android devices, and using the Bluetooth Low Energy protocol to acquire data from sensors. Then the data will be sent to the cloud or server. The results of the test give the results of the system being successfully implemented and IoT devices can be connected to the gateway with a maximum distance of 10 meters. Then when the system stores, for every minute there is an increase in data of 4 kb. Then there is no data redundancy in the system.

Published: September 2021

The search for the shortest path of the waste collection process is an interesting topic that can be applied to various cases, from a very practical basic problem to a complex automation system development. In a dense settlement, the waste collection system can be a challenging process, especially to determine the most optimized path. The obstacles can be circling streets, impassable roads, and dead-end roads. A wrong choice of method can result in wasteful consumption of energy. A possible method to solve the problem is the traveling salesman problem using ant colony search optimization, considering its relatively fast optimization process. Therefore, this paper proposes an application of ant colony and traveling salesperson problem in determining the shortest path of the waste collection process. The case study for the optimization algorithm application is the path UGM Sekip Lecturer Housing is considering. Firstly, the data was collected by measuring the distance between points. Then, the paths were modeled and then compared with the actual route used by waste transport vehicles. The last step is implementing the ant colony optimization and traveling salesman problem by determining the cost function and the parameters. The optimization process was conducted several times, considering the random generator within the algorithm. The simulation results show the probable shortest path with a value of about 752 meters so that the use of fossil fuels in waste transport vehicles can be more efficient. The results show that the algorithm can automatically recommend the minimized path length to collect waste.

Published: September 2021

Introducción: el trasplante renal es el tratamiento de elección para los pacientes con enfermedad renal crónica terminal. Sin embargo, un trasplante renal anticipado no siempre es posible, y muchos pacientes requieren algún tipo de terapia de reemplazo renal previo al trasplante. Este estudio tiene como objetivo evaluar los desenlaces a corto y largo plazo post-trasplante renal de acuerdo a la modalidad de diálisis previa al trasplante.

Métodos: estudio tipo cohorte restropsecitva. Se incluyeron pacientes mayores de 18 años que recibieron un trasplante renal durante 2005-2018. Inicalmente se realizó estadística descriptiva. Posteriormente se realizó análisis multivariado mediante un modelo de riesgos proporcionales de Cox con el objetivo de evaluar la relación entre la supervivencia del paciente y del injerto y la necesidad de diálisis previo al trasplante. Se evaluó además la tasa de filtración glomerular durante los primeros dos años del trasplante renal.

Resultados: durante 2005-2018 se realizaron 925 trasplantes renales, 289 estaban en diálisis peritoneal, 439 en hemodiálisis y 197 no estaban en diálisis. La supervivencia del paciente y del injerto a 6, 12, 24, 48, 60 meses posterior al trasplante renal fue de 97.5%, 96.7%, 96.0%, 93.7%, 92.3% y 94.5%, 92.9%, 90.5%, 84.8%, 81.1% respectivamente, sin encontrar diferencia estadísticamente significativa entre los que tuvieron diálisis peritoneal vs. hemodiálisis (p=0.402, p=0.180) tampoco se encontraron diferencias significativas en el análisis multivariado. El 8.1% de los pacientes presentó rechazo agudo en el primer año post trasplante, y el 13.2% durante todo el seguimiento, sin encontrarse diferencias significativas entre los que habían tenido diálisis peritoneal vs. hemodiálisis. No se encontraron diferencias en la TFG.

Conclusiones: no se encontraron diferencias estadísticamente significativas en los desenlaces duros a corto y largo plazo según la modalidad de diálisis pre-trasplante.

Published: September 2021

Introducción: El trasplante renal es considerado la terapia más efectiva para el tratamiento de la enfermedad renal crónica (ERC). Recientemente, el trasplante renal ha aumentado en los pacientes mayores de 60 años dado que presentan ventajas relevantes reportadas en la literatura mundial como menor riesgo de morir en comparación con pacientes de la misma edad que continúan en diálisis.

Objetivo: Evaluar la sobrevida del injerto y del paciente adulto mayor en una cohorte de pacientes trasplantados renales.

Materiales y métodos: Analizamos retrospectivamente una cohorte de 193 pacientes mayores de 60 años, quienes recibieron trasplante renal en el periodo comprendido entre 2008 a 2019 en nuestros centros de trasplante. Se analizaron variables sociodemográficas y clínicas para determinar la sobrevida del injerto y del paciente al año, 5 y 10 años post-trasplante mediante el método de Kaplan-Meier. Se realizó un modelo de regresión de Cox para evaluar los potenciales factores de riesgo para pérdida del injerto renal en el primer año post-trasplante.

Resultados: La media de edad de los pacientes fue de 64.62 ± 3.82 años. La sobrevida del injerto censurada por muerte fue de 90%, 86% y 75% en los años 1, 5 y 10 post-trasplante y la sobrevida del injerto no censurada fue de 82%, 63% y 43% en los mismos periodos documentados.  Las principales causas de mortalidad fueron infecciones y enfermedad cardiovascular.  La sobrevida del paciente adulto mayor fue de 89%, 70% y 55% en los años 1, 5 y 10 post-trasplante, respectivamente. Los factores de riesgo asociados a pérdida del injerto renal en el primer año post-trasplante fueron: edad mayor a 70 años (HR 4.2; 95% CI 1.1-15.3), sexo femenino (HR 2.7; 95% CI 1.01-7.3) y no adherencia al tratamiento (HR 8.1; 95% CI 2.1-30.7).

Conclusión: Los pacientes adultos mayores trasplantados tuvieron desenlaces adecuados en el trasplante renal. Es importante definir herramientas de evaluación del paciente adulto mayor que sean objetivas en el pre-trasplante donde la edad no sea una barrera de acceso al trasplante renal para esta población.

Published: September 2021

La insuficiencia hepática aguda sobre crónica (ACLF, Acute-on-chronic liver failure) es una entidad de reciente caracterización y se presenta como una descompensación aguda de una hepatopatía crónica, puede ir asociada a falla en diferentes órganos y presentar una alta mortalidad. Su incidencia alcanza hasta 30% de pacientes que consultan por complicaciones en cirrosis de base.Dentro de los factores precipitantes más frecuentes se encuentran infecciones bacterianas, alcoholismo y reactivación de hepatitis virales, pero, hasta en un 40% de los casos, no se identifica ningún factor precipitante. La fisiopatología de esta entidad aun es desconocida en cierta medida, pero se plantea la existencia de una respuesta inflamatoria excesiva en su desarrollo. No existe ningún tratamiento específico y su manejo se basa en el tratamiento para complicaciones asociadas, soporte y finalmente trasplante hepático. La disfunción renal es un hallazgo común en pacientes con enfermedad hepática. El síndrome hepatorrenal, que se pensó era de carácter meramente funcional y ahora, ante la evidencia de algún grado de daño tubular relacionado, se ha mejorado la comprensión de la fisiopatología de dicha entidad y ha obligado recientemente a replantear los criterios diagnósticos y la clasificación de la enfermedad. Describimos el caso clínico de una paciente atendida en un centro hospitalario en la ciudad de Pereira, Risaralda. Quien presentó bacteriemia por cocos gram positivos, de origen no claro, se consideró esta como el factor precipitante, tuvo deterioro clínico, con aparición de síndrome hepatorrenal y falla multiorgánica finalmente llevándola a la muerte a pesar de manejo multidisciplinario.

Authors: Torres Serrano Rodolfo Eduardo , Benavides Tamayo Helman Enrique
Published: September 2021

Antecedentes: La enfermedad renal cursa con alteraciones de la hemostasia aumentando el riesgo de eventos trombóticos y hemorrágicos.
Objetivo: Describir las anormalidades de la coagulación en pacientes con urgencia dialítica según tromboelastografía y pruebas convencionales.
Materiales y métodos: Serie de casos de 60 pacientes adultos con  urgencia dialítica. Se tomaron muestras de sangre previo al implante de catéter de hemodiálisis o de diálisis peritoneal, se procesaron para tromboelastografía y pruebas convencionales.
Resultados: En la interpretación global del tromboelastograma se identificó estado hipercoagulable en 60% de los pacientes. En el análisis individual de parámetros del trazado se demostraron alteraciones en la fase enzimática con ángulo-alfa aumentado en el 61.7% y tiempo R acortado en el 58.3% de los casos, alteraciones en la fase celular con MA y G aumentados en cerca del 45% y alteraciones en la estabilidad con hiperfibrinolisis en el 18%. El aPTT estaba prolongado en 23.7%.
Conclusiones:  En la interpretación global de la tromboelastografía de pacientes con urgencia dialítica el hallazgo mas frecuente es el estado hipercoagulable. En el análisis individual se encontraron alteraciones en todas las fases de la coagulación, siendo la mas frecuente la formación acelerada del coágulo, seguida por aumento de la fuerza del mismo. La tromboelastografía debería ser considerada como una prueba enfocada en la cabecera del paciente para la valoración de la hemostasia en estos pacientes.

Dimensão religiosa, moral e cultural da água. Uma análise do ponto de vista do Direito Internacional.
Authors: Espada Gildo Manuel , Espada Ivete Marlene Marlene Rosária Mafundza
Published: September 2021

Quando se fala de água, é geralmente para analisá-la do ponto de vista de bem essencial para o consumo humano, strictu sensu. Isto é, como elemento essencial para a sobrevivência, considerando seus principais usos: para o abeberamento, para as lides domésticas, para a agricultura e, quiçá, para a manutenção dos ecossistemas. Quando não é esta a abordagem, a água é vista como elemento de aproximação ou separação dos povos. Isto é, como via de comunicação, ou como fonte de conflito. Em última instância, fala-se da água como parte da natureza, que tem um ciclo próprio: o ciclo da água. É este o problema que nós analisamos: será que há consciência das várias dimensões da água? Por isso, este artigo faz uma abordagem diferente da água: fala da sua dimensão cultural, moral e religiosa, com objectivo de abordar a água em perspectivas diferentes. Porque a água é um elemento essencial para a preservação dos valores morais, religiosos e culturais. O artigo foi feito com base em pesquisa bibliográfica e procura fazer uma análise global, que não se limita a nenhum país ou região. A conclusão a que chegamos é que a água tem uma importância e dimensão para a moral, religião e cultura dos povos muito maior do que é geralmente atribuída, devendo por isso incrementar a proteção e divulgação dos valores morais, culturais e religiosos deste bem que é essencial para a humanidade.

Published: September 2021

O artigo tem o objetivo de investigar a influência dos manuais de direito romano na formação intelectual de Clóvis Beviláqua. A importância da pesquisa é identificar as correntes teóricas que contribuíram para a formação do pensamento de Beviláqua, autor do Código Civil de 1916. Para tanto, o presente artigo segue os rastros dos manuais e os autores estrangeiros lidos por Beviláqua, assim como as lições do seu professor de direito romano e o contexto intelectual da Faculdade de Direito do Recife. Trata-se, portanto, de um exercício de história do direito que pretende demonstrar a sintonia entre a produção e o pensamento deste autor com a época em que viveu e o processo de construção da cultura jurídica brasileira.
A Escola de Salamanca: um caso de produção global de conhecimento
Authors: Duve Thomas
Published: September 2021

Neste artigo, apresento algumas reflexões sobre como conceitualizar o que foi rotulado como “Escola de Salamanca”, um movimento intelectual do século XVI e início do século XVII desenvolvido na Universidade de Salamanca. Após reconstruir o desenvolvimento do conceito “Escola de Salamanca” no fim do século XIX e início do século XX, sugiro considerar o movimento intelectual ora discutido sob essa denominação como tanto uma comunidade epistêmica quanto uma comunidade de prática que se estendeu para muito além das fronteiras de Salamanca, Espanha e da Península Ibérica. Mais adequadamente, ela pode ser compreendida como uma parte e um dos centros de uma rede global de produção de conhecimento no campo da normatividade.
A vulgata da tríade poética (lírico, épico e dramático) no ensino de roteiro para cinema e audiovisual
Authors: Suppia Alfredo
Published: September 2021

Lírico. Épico. Dramático. O que são essas categorias? Por que são reiteradamente referidas, com frequência, no ensino de roteiro para cinema e audiovisual (AV)? E por que a autoria dessas mesmas categorias é, não raro, atribuída à obra Arte Poética (ou simplesmente Poética), de Aristóteles? Lírico, épico e dramático compõem a famosa tríade canônica, uma suposta matriz genérica da qual todos os gêneros literários emanam, ou da qual teriam se desenvolvido. Largamente aplicada ao estudo dos gêneros literários, a tríade canônica tem seu devido impacto nos estudos de cinema, notadamente na teoria e prática do roteiro contemporâneo. É sabido que, embora em constante renovação, o campo do cinema e AV conserva modelos e axiomas provenientes de trabalhos pioneiros muito antigos, como a Poética de Aristóteles ou A República de Platão, assim como de propostas e reflexões mais recentes, como as do formalismo russo. Este artigo pretende re-examinar a permanência dos “gêneros” lírico, épico e dramático no ensino do roteiro cinematográfico e AV, levando em conta parte da história dos gêneros literários e esforços predecessores de teorização, tanto no âmbito dos estudos literários, quanto no dos estudos de cinema e AV. Nesse sentido, pretendemos indagar sobre por que as categorias do lírico, do épico e do dramático são reiteradamente referidas no ensino de roteiro para cinema e AV, com sua “paternidade” frequentemente atribuída, por engano, à Poética de Aristóteles. Investigaremos também qual a origem de tais termos, bem como sua aplicabilidade no ensino contemporâneo de roteiro.
