Published: September 2023

Electric vehicles (EV) have become very significant and potential way to reduce greenhouse gas emissions on a worldwide scale. EV also provides Energy security, as it reduces the dependency on petroleum producing countries of the world. Similar to the conventional Internal Combustion Engine Cars, in Electrical Vehicles also the efficient air conditioning system is very important for providing thermal comfort and for giving safe driving conditions. In Air Conditioning systems for EV, the heating option is available in the form of Electrical heaters and Heat Pump systems. The Heat pumps have become more popular compared to the electrical Positive Temperature Coefficient (PTC) heaters because of their highly efficient and energy saving designs. However, there are still some issues with using heat pumps. One of such issue is their less Coefficient of performance (COP) at low ambient conditions. Experimental results also show that the driving range decreases by using the electric heating system in vehicles.

This paper presents a study on the solutions for increasing the efficiency of heat pump at low ambient conditions. The waste heat coming out from the Traction Motor and power electronics of Electric Vehicles is being utilized for increasing the temperature of Air, which is entering the condenser in Heating mode. This has been done using a heat Exchanger placed in front of the condenser. The study is being evaluated using Coil Designer software for component level simulations and further for the system level simulations, the Kuli software has been used. The study has also resulted in increasing the COP of the system in the Heating Mode.
A Methodology to Thermally Manage Li-Ion Battery Systems and Prevent Catastrophic Thermal Runaways
Authors: Srinivasan Srikumar
Published: September 2023

An online report mentions that a conventional ICE vehicle in its lifetime of 12 years or 150000 km will emit 40 tons of CO2e. With tightening of the norms and countries setting emission targets, nowadays vehicle manufacturers are bringing out many new models of electric vehicles. The sale of EV vehicles are not without challenges. The electric vehicles traditionally require an e-motor for motive force, that are powered largely by Li-batteries located in a battery box. The batteries discharge when vehicles are running and get charged through the grid normally. When batteries charge and discharge, heat is dissipated. Generation of heat is a concern, since it reduces the life of a battery with life of battery depending on number of charge /discharge cycles. In an ideal condition a Battery Management System (BMS) ensures that the batteries are charged / discharged at optimal dissipated thermal load. However due to various random events like cell breakdown, mechanical damage to batteries, etc., the batteries could emit uncontrolled heat - which leads to a situation called “Thermal Runaways”. This thermal runaway may lead to fire, battery damage and in the worst case, a whole vehicle could get destroyed. So, it’s imperative to control the thermal run-away situation, by containing the fire within battery box and avoid fire propagation that could destroy whole vehicle. Such a method could limit the damage only to the Li-Ion battery box (in current configuration) and the vehicle itself could be saved and in some cases, precious human lives. There are many methods to deal with this event (ref . point b, point c). In this paper, we discuss one such method that could be a potential life/equipment saver.

Authors: Goel Arunkumar , Sen Somnath
Published: September 2023

As the automotive industry is transitioning from conventional engine driven to electric battery driven, many of the vehicle aggregates are getting re-engineered and changing accordingly. Being air-conditioning manufacturer one of the aggregates that needs attention and focused effort is the Heating Ventilation and Air Conditioning system (HVAC). Acoustic comfort of electric vehicle gets impacted due to the HVAC noise in absence of engine and hence other noise sources becomes prominent which were earlier masked by the engine noise. It is important to understand the HVAC noise sources for implementing right countermeasures for masking the noise. There are three methods of noise source identification namely acoustical duct method, cocooning or lead covering method and near field method. Out of these method, acoustical duct method and near field methods are used for minor and major noise identification in this study.

The present paper describes the comparative study of HVAC noise source identification using acoustical duct method and near field method. Significant amount of works has been done in past with these two methods as these are quick and easy methods to identify the sources of noise. An automotive HVAC was used for the study and was kept in a semi-anechoic chamber with input voltage of 12.5V DC being supplied. Noise measurement was carried out from these sources namely blower motor, fresh/recirculation opening, face and defrost air outlet. A comparative study was carried out to understand the difference and to evaluate the right method to figure out these noise sources and to identify the limitations of both methods. The study shows a good trend between near field method and acoustical duct method in order to understand the prominent noise sources and take appropriate countermeasures. Hence the study is quite useful in early design stage for better taking the right design alternatives.

Impact Analysis of an Alternate Environment Friendly Refrigerant Deployed in the Air Conditioning System of IC Engine and Electric Vehicles
Authors: Maurya Anurag , Mehta Bhavik , Sardesai Suresh , Swarnkar Sumit , Venu Santosh , Kapoor Sangeet
Published: September 2023

Today, most vehicles in developing countries are equipped with air conditioning systems that work with Hydro-Fluoro-Carbons (HFC) based refrigerants. These refrigerants are potential greenhouse gases with a high global warming potential (GWP) that adversely impact the environment. Without the rapid phasedown of HFCs under the Kigali Amendment to the Montreal Protocol and other actions, Earth will soon pass climate tipping points that will be irreversible within human time dimensions. Up to half of national HFC use and emissions are for the manufacture and service of mobile air conditioning (MAC). Vehicle manufacturers supplying markets in non-Article 5 Parties have transitioned from HFC-134a (ozone-safe, GWP = 1400; TFA emissions) to Hydro-Fluoro-Olefin, HFO-1234yf (ozone-safe, GWP < 1; TFA emissions) due to comparable thermodynamic properties. However, the transition towards the phasing down of HFCs across all sectors is just beginning for Article 5 markets. Patents on R-1234yf will soon expire, just as scarcity is likely to drive the price of R-134a to historic highs.

This work consists of two case studies, specific to an Internal Combustion Engine (ICE) and an Electric Vehicle (EV). Two different refrigeration system architectures are examined. Both the shortlisted vehicles have different and complex AC system architectures. Complex AC system architectures are selected in this study with the objective of understanding and deploying the learnings in vehicles with less complex and simpler AC system architectures. The ICE vehicle selected for the study has a dual AC configuration with two cooling points (front and rear), using DX architecture. In the EV, an architecture similar to that of the ICE vehicle is deployed for cabin cooling, but unlike the ICE vehicle, it has a secondary coolant-based loop provisioned for battery thermal management. For this study, the baseline HFC-134a refrigerant is replaced by a ‘drop-in’ alternate low-GWP HFO-1234yf refrigerant in both vehicles.

This study focuses on cooling performance evaluation with existing HFC refrigerant and proposed HFO refrigerant for both AC system architectures, gap identification, and proposing common and unique solutions for bridging the performance gaps.
The Threat of Conventional Weapons to Nuclear Security: A New Reality for Deterrence
Authors: Rautenbach P.
Published: September 2023

This paper explores the idea that developments in Conventional Prompt Global Strike (CPGS) systems degrade nuclear security. The United States is developing such weapons for niche conventional use on the surface, but the line between tactical and strategic weapons is becoming blurred. What is more, while there have been discussions in Congress surrounding the problem of missile ambiguity, there is a multitude of other problems, with the largest being that CPGS weapons inherently degrade nuclear security. By looking at the behavior of critical states and actors involved in the emergence of CPGS weapons and combining this with pre-existing literature and insight on similar topics within international relations, we then can conduct a thorough investigation on the impact of these CPGA systems. When compared to nuclear missiles, the increasing usability of these weapons is inherently dangerous, as it increases both the likelihood of their use and the likelihood of a first strike against another state’s nuclear deterrent. Traditionally, conducting a first strike has been all but impossible because it entailed using nuclear weapons, which come with ethical and environmental consequences. If nuclear weapons can be replaced or substituted with CPGS weapons, then a first strike becomes an actual possibility. Hence, as a result, the nuclear doctrine is changing to reflect this conventional danger and has led to a lower threshold for nuclear use. This fact then demonstrates clear signs that CPGS technology degrades nuclear security and thus increases the chance of nuclear use.

El deber objetivo de Cuidado conforme al Reglamento y Ley del Ejercicio Profesional de los Anestesiólogos
Authors: Lama Tapia Hamilton Jotyin , Pérez Ycaza Juan Carlos
Published: September 2023

La infracción al deber objetivo de cuidado (IDOC) es una figura introducida en Ecuador en el 2014 con el COIP, con 4 requisitos concurrentes. Para las actuaciones de los Anestesiólogos es necesario evaluar conjuntamente: la ley y reglamento de la especialidad, las normas mínimas de seguridad de la CLASA y los documentos sobre “cirugía segura” de la OMS. Investigamos en este artículo si existe relación entre estas últimas normas y los requisitos mencionados. El objetivo es encontrar la antes mencionada relación y revisar su realidad procesal. Para ello realizamos análisis documental mediante lógica jurídica. Como resultado obtuvimos una correspondencia entre estas normas y los elementos de la IDOC, así como una ausencia de su consideración dentro de las sentencias evaluadas. Se concluye que, si bien son legalmente exigibles, estas normas no son siempre analizadas cuando se juzga una supuesta IDOC, por lo que es necesaria su incorporación al ámbito judicial.

Authors: Galarza Pazmiño María De Los Ángeles , Castillo Galvis Sergio Hernando
Published: September 2023

A nivel mundial, la violencia intrafamiliar es considerada un problema de salud pública por su amplia variabilidad de presentación, que genera múltiples consultas médicas y eleva los costos sanitarios. El objetivo de estudio mediante muestreo casual no probabilístico de revisión de artículos científicos para determinar el manejo judicial de los profesionales sanitarios de esta problemática, encontrando que en el 52% se reportó sistemas de referencia, soporte legal o del deber de denunciar; en ninguno se establece la posibilidad rendir testimonio experto por el profesional de la salud. La falta de capacitación especializada, desafíos en la detección y cribado, la escasez de recursos y servicios especializados, y las consecuencias negativas para las víctimas de la falta de atención adecuada contribuyen a una respuesta ineficiente en la atención a las víctimas de violencia intrafamiliar. Es fundamental mejorar la formación de los profesionales de salud, fortalecer la atención interdisciplinaria y promover una respuesta más efectiva a este grave problema.

Authors: Buenaño Taboada Karla Estefanía , Castillo Galvis Sergio Hernando
Published: September 2023

El presente artículo discute los aspectos médicos y legales de la práctica médica, particularmente la importancia de los registros médicos o historia clínica en el contexto de la responsabilidad médica y los casos legales. La historia clínica se define como un documento médico creado para registrar todos los procedimientos médicos realizados a un paciente y facilitar su atención, por lo que este debe ser completo, secuencial, claro, legible, comprensible, corregido si es necesario y veraz. La omisión de información, incluida la falsificación de datos o la omisión de información importante, puede tener consecuencias negativas para los pacientes y los profesionales médicos, por lo que también este se utiliza como evidencia en casos legales, y su integridad y precisión son esenciales en los tribunales. El tipo de investigación es cualitativo y descriptivo. Los resultados se obtuvieron tras el análisis de sentencias, donde se pudo concluir que omitir información de los registros médicos puede tener consecuencias significativas tanto para la calidad de atención médica como para la responsabilidad médica, dificultando la defensa en los juicios.
Empreendedorismo e ensino superior politécnico: contornos de implementação do programa poliempreende
Authors: Sousa Luis
Published: September 2023

A aparente inadequação das qualificações obtidas pelo número crescente de licenciados e as exigências do mercado de trabalho, vêm mudando a direção e a proeminência do fenómeno do desemprego, resultando numa reestruturação da desclassificação do emprego jovem. A crescente falta de linearidade entre o sistema de ensino superior e o mercado de trabalho tem vindo, assim, a aumentar em Portugal, revelando novas lacunas, tornando o processo de transição de diplomados do ensino superior para o mercado de trabalho e para a vida adulta, num processo complexo e instável. Esta situação é representada pelo aumento da concorrência no mercado de trabalho, pelas taxas de desemprego e pela crescente falta de ligação entre as qualificações, competências pessoais e profissionais, oportunidades de carreira e expetativas profissionais. Este movimento vem ganhando, nos últimos anos, vitalidade crescente e, atualmente, representa uma grande preocupação para as várias instituições que estão diretas e indiretamente envolvidas neste processo. Promover o empreendedorismo constitui hoje um dos principais aspetos na formação de graduados e, simultaneamente, um apoio à transição para o processo de trabalho. O Poliempreende (9 ª edição em 2013) representa os esforços do Ensino Superior Politécnico neste movimento, e nós pretendemos aqui contextualizá[1]lo no cenário nacional, assim como verificar, de uma forma exploratória, os seus contornos de aplicação, até ao momento.

O presente estudo tem como objetivo identificar a autoperceção das competências profissionais dos professores de Educação Física do concelho de Viseu. Concebemos o nosso estudo baseado na investigação quantitativa, em que utilizamos um plano não experimental descritivo por inquérito. Após o levantamento do número total de professores que lecionam nas escolas deste concelho, foi aplicado um questionário de Nascimento (1999) e Feitosa (2002), adaptado para Portugal por Batista (2008), denominado “Escala de Autoperceção de Competência Profissional em Educação Física e Desportos”, a partir da qual foi constituída a nossa amostra de 69 professores. Para analisarmos os resultados, utilizámos técnicas de estatística descritiva, médias, frequências e desvios padrão, e a técnica de estatística comparativa T-Teste. Os resultados indicam que existe diferenças estatisticamente significativas entre as habilitações académicas dos professores de Educação Física e a autoperceção de competência profissional, nas dimensões conhecimentos, habilidades e atitudes. Por sua vez, os resultados apontam no sentido da existência de diferenças estatisticamente significativas entre os grupos de docência 260/620 e a autoperceção de competência profissional, na dimensão conhecimentos.
Previsão de preços de moeda e informação de eficiência: mercados equitativos vs swaps
Authors: Abidin Sazali , Banchit Azilawati , Sun Yuewei
Published: September 2023

Este estudo examina a capacidade de previsão dos Swaps em Risco de Incumprimento (SRI) e dos mercados de ações, relativamente à taxa de câmbio da moeda, para determinar se os SRI são um melhor indicador comparativamente aos mercados de ações. Os conjuntos de dados utilizados para este estudo incluem os índices de SRI norte-americanos Investment Grade (IG) e High Yield (HY) e o índice europeu iTraxx, em representação das condições gerais do mercado de crédito europeu. O índice de mercado Vanguard Total Bond está incluído para verificar se o spread do SRI constitui uma fonte de informação mais poderosa do que o mercado de obrigações. O índice S&P500 é utilizado como controlador para os efeitos do mercado de ações americano, sendo o índice Vanguard European Stock utilizado para a Europa. Os índices ASX200 e NZ50 foram escolhidos para representar as condições dos mercados de ações na Austrália e Nova Zelândia respetivamente. O modelo vetorial autorregressivo (VAR) é empregue para analisar as relações simultâneas entre as taxas de câmbio e os spreads do índice SRI.O teste Granger de causalidade é levado a cabo para determinar a relação causal entre os valores da moeda e os spreads do índice SRI. A Decomposição da Variância ou decomposição da variância do erro de previsão é igualmente utilizada para complementar a análise dos SRI. Esta análise conclui que os SRI conseguem capturar melhor a informação no mercado do que outros instrumentos de investimento, tais como as obrigações. Assim, os SRI poderão constituir uma oportunidade de arbitragem para os investidores. Complementarmente, foram encontrados efeitos significativos da causalidade Granger , dos spreads SRI IG e HY para as moedas, o que demonstra que os spreads SRI são um indicador importante das diversas moedas face ao dólar americano, mesmo numa crise financeira. Os resultados da decomposição de variância indicam que a contribuição do mercado dos SRI para o mercado da moeda é maior no caso do dólar australiano, o que implica mais carry-trades no mercado.
Volatilidade e ligações entre os mercados bolsistas internacionais: da crise das empresas tecnológicas à crise financeira global
Authors: Gabriel Vitor , Manso José
Published: September 2023

Neste estudo é analisada a volatilidade dos mercados bolsistas internacionais e a ligação entre estes, recorrendo a um conjunto composto por doze mercados, correspondente a mais de 62% da capitalização bolsista mundial, no período compreendido entre 4/01/1999 e 30/06/2011, tendo em consideração a diferenciação proporcionada pelos movimentos de subida e de queda dos mercados. Por um lado, aplica-se o conceito de semicorrelação, na aceção de Erb, Harvey e Viskanta (1994), de modo a perceber se as ligações entre os mercados registaram alterações significativas com a verificação de movimentos de queda dos índices, e em que medida a crise financeira global terá contribuído para tal. Por outro lado, foi analisado o risco dos mercados, em função dos movimentos descritos pelos índices, recorrendo ao conceito de semivolatilidade, de acordo com a proposta de Zimmermann et al. (2003).

Authors: Marques Ermelinda , Pinto Margarida , Nunes Maria
Published: September 2023

As pessoas ostomizadas experienciam uma situação de stresse, decorrente do enorme impacto físico e emocional que, quer a doença, quer o seu tratamento, impõem na sua vida, implicando alterações profundas no seu eu, nos estilos de vida, nas relações familiares e sociais, na sua imagem corporal e na autoestima. Assim, o estudo deste grupo específico torna-se uma exigência e, mais concretamente, o estudo da sua qualidade de vida. O principal objetivo deste trabalho consistiu em avaliar a perceção que a pessoa ostomizada tem sobre a sua qualidade de vida, bem como identificar e analisar os fatores determinantes da mesma. A presente investigação centrou-se nas 197 pessoas ostomizadas de um Agrupamento de Centros de Saúde da Região Centro de Portugal, recorrendo-se a uma amostra não probabilística por conveniência, constituída por 51 indivíduos. Realizou-se um estudo de natureza quantitativa, descritivo, analítico e transversal. Para a recolha dos dados foi utilizado um questionário elaborado especificamente para o estudo, de forma a permitir um melhor conhecimento sobre a pessoa ostomizada, e uma escala traduzida e testada na população portuguesa para avaliar a perceção da qualidade de vida, o SF-36. Como resultados principais, aponta-se que as pessoas ostomizadas percecionam melhor qualidade de vida nas dimensões relativas ao desempenho emocional, saúde geral e desempenho físico e pior qualidade de vida, ao nível da função física, dor corporal e função social. Foram identificados e analisados os fatores determinantes da qualidade de vida, nomeadamente: as características sociodemográficas (género, estado civil, situação profissional, escolaridade), as características relativas à ostomia (tempo de cirurgia, temporalidade do estoma, informação pré[1]operatória, tipo de admissão para a cirurgia, patologia que levou à cirurgia, prestador de cuidados) e o apoio. Os resultados desta investigação apontam para a necessidade de um estreito acompanhamento de enfermagem à pessoa ostomizada e dos seus familiares/cuidadores, de forma a minimizar o impacto negativo resultante da presença da ostomia.

Authors: Fernandes Fábia , Silva Bruno , Rodrigues Tiago , Costa Nuno , Camões Miguel , Bezerra Pedro
Published: September 2023

A literatura tem encontrado uma associação positiva entre exercício e melhor perceção do estado de saúde em pessoas mais velhas. No entanto, poucos estudos com intervenções em contexto comunitário, menos controlado, suportam esta associação. O objetivo deste estudo foi perceber a relação de dependência entre a prática de exercício físico e a respetiva melhoria na auto perceção de saúde de indivíduos acima dos 70 anos. Desta forma realizou-se um estudo transversal, com 250 indivíduos (74,8% sexo feminino), recrutados no norte de Portugal, e avaliados segundo quatro contextos diferentes. O Grupo 1 (N=148) identifica idosos comunitários envolvidos em programas de exercício físico; o grupo 2 (N= 41) inclui idosos comunitários que não estão envolvidos em prática regular de atividade física; os grupo 3 (N=37) e 4 (N=24) correspondem aos idosos que frequentam centros de dia e instituição, respetivamente, e que não praticam exercício físico. Para avaliar a perceção do estado de saúde utilizou-se o questionário SF36 nos seus oito domínios. Recorreu-se à regressão linear múltipla para testar as tendências entre grupos. Independentemente da idade, nos domínios da Função Física, Saúde Mental e Vitalidade, observou-se uma tendência significativa, com os melhores resultados a pertencerem aos idosos envolvidos em programas de exercício. Programas de intervenção com base em exercício físico têm um impacto importante nas diferentes dimensões que conferem qualidade de vida aos idosos.

Beton adalah bahan konstruksi umum yang dapat ditemukan di seluruh dunia. Namun, terlepas dari kenyataan bahwa ada banyak jenis beton dari hari ke hari yang menghasilkan jumlah hari yang sama, ada opsi ketiga yang dapat digunakan untuk mencapai tujuan ini: pembuatan hasil limbah-limbah.Contoh yang paling nyata adalah penggunaan tebu sawit.Cangkang kelapa sawit dapat dimanfaatkan sebagai pengganti beton.Dalam penelitian ini, cangkang kelpa sawit digunakan sebagai pengganti agregat kasar pada beton untuk lima variasi yang berbeda: variasi I (beton normal), variasi II (substitusi 5% cangkang kelapa sawit), dan variasi III (substitusi 10% cangkang kelapa sawit). Setiap variasi membutuhkan minimal 12 slindSlump test, kuat tekan, serap, dan pengamatan pola retak dilakukan pada hari ke 28 setelah kelahiran benda.Peningkatan nilai absorbsi dan penurunan nilai slump, kuat tekan, dan kuat tekan penyebab utama masalah tersebut.Dalam kasus pola retak, penggantian cangkang kelapa sawit menghasilkan jumlah, Panjang, dan rentang lebar retak yang jauh lebih umum daripada silinder biasa.Hal ini menunjukkan bahwa kerikil memiliki teks yang lebih halus dan keras dari sawit sebelumnya. Hasilnya, terlihat bahwa cangkang kelapa sawit tidak memenuhi syarat sebagai agregat kasar.

Kondisi tanah dibawah struktur begitu berhubungan dengan sifat tanah itu sendiri ketika mendapat beban, kegagalan yang terjadi pada sub-grade pondasi timbunan yaitu tanah pondasi terlalu lunak sehingga daya dukung tanah, dalam menahan beban timbunan kecil, sehingga penurunan  yang terjadi sangat besar. Lapisan tanah yang ada dibawah bangunan tersebut harusla kuat, stabil, aman, sehingga tidak mengalami penuruna , retak, karena  sulit mempebaiki struktur atas bila hal ini terjadi. Tujuan penelitian ini adalah agar menganlisa besarnya penurunan akibat material penimbunan pada lokasi proyek KILANG MINYAK PT. INDUSTRI NABATI LESTARI SEI SEMANGKEI. Penurunan tanah proyek akan mempengaruhi kontruksi dimasa depan, penurunan yang terlalu besar menimbulkan kerusakan yang lumayan berpengaruh terhadap kontruksi. Oleh sebab itu dilakukan analisa kpada besarnya penurunan. Berdasarkan perhitungan yang dilakukan kepada design timbuna bahu jalan di atas tanah lunak di lokasi pekerjaan  dapat disimpulkan : 1). Untuk penurunan konsolidasi, semakin tinggi tanah timbunan semakin lama proses penurunan, 2).Hasil Sc pada BH – 01  lebih besar dari Sc pada BH – 02, hal ini dikarenakan angka pori pada sampel BH – 01 lebih kecil dari BH – 02. Proses pembebanan sangat dipengaruhi oleh nilai void ratio yang terkait dengan permeabilitas atau sifat kelolosan air, 3).Nilai K pada BH – 01 lebih kecil dari BH – 02. Semakin bertambah besar nilai permeabilitas maka proses terdissipasinya angka pori akan semakin cepat. Sehingga penurunan yang terjadi akan semakin besar, 4).Nilai Coeffisient Index Cc mempengaruhi besarnya penurunan, semakin besar  nilai Coeffisient Index Cc, semakin besar penurunan yang terjadi.

Published: September 2023

The present study investigates the effects of assertiveness training programs through folk dances on high school students’ assertiveness levels. Pre-test post-test with control group design has been used to examine. Furthermore, a questionnaire including one open-ended question asked students to learn their opinion on training and its effects on themselves. Experiment and control group participants were administered the Rathus Assertiveness Inventory, and experiment group participants received a two–hour assertiveness training program through folk dances per week over eight weeks. The study sample included 203 students who were in first grade in the same school. Results revealed that students in the experiment group had significantly higher assertiveness levels than those in the control group (P<0.05), and experiment group students defined that this assertiveness training program positively affected them and increased their awareness about themselves.
