Quantification of Temperature-Dependent Sorption Isotherms in Shale Gas Reservoirs: Experiment and Theory
Authors: Yang Yun , Liu Shimin , Clarkson Christopher
Published: March 2022

A critical component of natural gas in organic-rich shales is adsorbed gas within organic matter. Quantification of adsorbed gas is essential for reliable estimates of gas-in-place in shale reservoirs. However, conventional high-pressure adsorption measurements for coal using the volumetric method are prone to error when applied to characterize sorption isotherm in shale gas systems due to limited adsorption capacity and finer pores of shale matrix. Innovative laboratory apparatus and measurement procedures have been developed to accurately determine the relatively small amount of adsorbed gas in a Marcellus shale sample.

The custom-built volumetric apparatus is a differential unit composed of two identical single-sided units (one blank and one adsorption side) connected with a differential pressure transducer. The scale of the differential pressure transducer is ±50 psi, a hundred-fold smaller than the absolute pressure transducer measuring to 5,000 psi, leading to a significant increase in the accuracy of adsorption measurement. Methane adsorption isotherms on Marcellus shale are measured at 303, 313, 323, and 333 K with pressure up to 3,000 psi. In addition, a fugacity-based Dubinin-Astakhov (D-A) isotherm is implemented to correct for the nonideality and to predict the temperature dependence of supercritical gas sorption.

The Marcellus shale studied generally displays linear correlations between adsorption capacity and pressure over the range of temperature and pressure investigated, indicating the presence of a solute gas component. It is noted that the condensed-phase gas storage exists as the adsorbed gas on the shale surface and dissolved gas in kerogen, where the solute gas amount is proportional to the partial pressure of that gas above the solution. One of the major findings of this work is the experimental observation of the contribution of dissolved gas to total gas storage. With adsorption potential being modeled by a temperature-dependence expression, the D-A isotherm can successfully describe supercritical gas sorption for shale at multiple temperatures. Adsorption capacity significantly decreases with temperature attributed to the isosteric heat of adsorption. Lastly, the broad applicability of the proposed fugacity-based D-A model is also tested for adsorption data provided in the literature for Woodford, Barnett, and Devonian shale. Overall, the fugacity-based D-A isotherm provides precise representations of the temperature-dependent gas adsorption on shales investigated in this work. The application of the proposed adsorption model allows predicting adsorption data at multiple temperatures based on the adsorption data collected at a single temperature. This study lays the foundation for an accurate evaluation of gas storage in shale.
Diffusion indexes of state and metropolitan area employment changes
Authors: Lepoutre TJ
Published: March 2022

The U.S. Bureau of Labor Statistics publishes eight diffusion index series that measure the dispersion of employment change across either all 50 states and the District of Columbia or 389 metropolitan statistical areas. These data provide a tool for analysis of employment changes and additional information about the labor market. This article explains how the diffusion indexes are calculated, examines the differences between the indexes, and describes how the data are interpreted and how the data respond during economic turning points and the coronavirus disease 2019 pandemic.

In malaria elimination programs, surveillance is a critical component. In Indonesia, an electronic information system was created to carry out malaria surveillance inthe form of a structured excel file as part of an attempt to enhance the validity andcompleteness of reporting malaria data. However, the use of this method hasseveral obstacles that are still felt by health workers. This study designed anAndroid-based malaria surveillance application as an alternative solution to themethod that has been applied. The evaluation results show that the overall impression of this application is very good (mean, median (on a 9-point scale) andstandard deviation equal to 6.84, 6.88 and 0.29, respectively). This means that ingeneral, health officers as application users are satisfied with the applications that have been developed. Keywords: malaria, surveillance, Android, design,evaluation

Authors: Burbano Bravo Juan Pablo , Casas Perdomo Valentina , Gómez López Maria Alejandra
Published: March 2022

Los diferentes estudios de la ideación suicida han sido llevados a configurar la idea del suicidio en su definición, su sentido y su incidencia, dejando un rastro de factores que permean a jóvenes y adultos. El propósito central de este artículo es visibilizar las afectaciones emocionales que se presentan, tanto en jóvenes universitarios con ideación suicida como en profesionales que han atendido a jóvenes con ideación suicida, caracterizando las afectaciones emocionales de los profesionales y los jóvenes atendidos. Las afectaciones emocionales son los pilares con los cuales cuenta este documento, debido a que son muy pocos los estudios que hablan acerca de esto. Se plantea así la identificación de factores emocionales presentes en los jóvenes de universidad pública que son atendidos por ideación suicida, y por último se contrastaran las afectaciones emocionales de los jóvenes de universidad pública y los profesionales en el proceso de atención en ideación suicida, para así conocer qué afectaciones similares presentan estos dos grupos investigados. Para el desarrollo de este análisis se utilizó el enfoque cualitativo, en función del diseño fenomenológico hermenéutico. Este método constituye esquemas vivenciales y expresivos de las dimensiones donde la fisionomía grupal evidencia la trastienda de la experiencia cotidiana individual.

Authors: Pimentel Maurício Ragagnin , Castrogiovanni Antonio Carlos
Published: March 2022

A proposta deste estudo foi compreender como espaço designado como 'Porto Alegre' é apresentado e significado enquanto turístico. Realizou-se uma análise de discurso, com exame 135 documentos de diferentes épocas e gêneros textuais. Metodologicamente, atribui-se a todos os textos pesquisados um patamar de igualdade, independente de sua autoria, data e cenografia. Como resultado apontam-se cinco balizas a partir das quais a cidade é descrita e significada: ‘evocação geográfica’; ‘enquadramento temporal’; ‘lugar e seus personagens’; 'ideais de urbanidade' e ‘ identidade do gentílico'. Em um contexto do crescimento da participação dos serviços na economia urbana e do uso frequente do turismo como subterfúgio para projetos com repercussões importantes na vida das cidades, este trabalho procura contribuir ao apontar os processos discursivos de transformação de um espaço em turístico. Também evidência o caráter situado e político do que é compreendido enquanto turismo e qual papel é atribuído à figura do turista.
As paisagens de férias em Lago Merín (Uruguai): olhares e práticas
Authors: Kunz Jaciel Gustavo
Published: March 2022

A Lagoa Mirim é a maior de seu gênero no Brasil e no Uruguai. Contudo, segue pouco estudada na sua função turístico-recreativa, bem como no que tange a percepções e representações de sua paisagem por turistas/lazeiristas. Lago Merín, no nordeste uruguaio, é um dos sítios de encontro com essa Lagoa, e se constitui como uma versão turística particular do todo da paisagem lacustre estudada. Desse modo, a pergunta norteadora foi: Como os sujeitos interpelam as paisagens lacustres de Lago Merín em suas temporadas de veraneio? Como objetivos específicos, interpôs-se: i) caracterizar o sítio “Lago Merín” a partir de trajetórias de (des)encontro de turistas/lazeiristas com a Lagoa Mirim; ii) investigar o tipo de olhar turístico evocado na mirada a suas paisagens; iii) identificar as práticas turístico-recreativas que comumente ocorrem no sítio pesquisado, durante o veraneio. Para tal, assume-se o método da Complexidade em Morin (2015). Os dados multifocais foram coletados por meio de documentos (oficiais, comentários no Trip Advisor e fotografias do Instagram) e pesquisa de campo (entrevistas semiestruturadas e observação direta). Os dados passaram por análise qualitativa de conteúdo. Foi possível evidenciar a trajetória socio-histórica de formação do Balneário. O olhar turístico coletivo parece predominar. As práticas observadas são mais vastas que as enunciadas. Une-se, pois, a perspectiva das paisagens de férias (LÖFGREN, 1999) com o olhar coletivo dos turistas (URRY, 1999b), o que se dá por meio de práticas contingentes, embora ainda conformistas, para além das materialidades. Ao final, apontam-se limitações da pesquisa, bem como rumos para futuras agendas.
Neocolonialismo como causa e Turismofobia como efeito: Uma aproximação a partir da Geografia
Authors: Gastal Susana de Araújo , De Sá Felipe Zaltron
Published: March 2022

O estudo do Turismo ganha status acadêmico considerando-o como prática social e ciência inter e transdisciplinar que permite diálogos, entre outros, com os estudos geográficos. Tais aproximações levam a maior entendimento do mesmo, especialmente nas suas tensões decorrentes da estrutura econômica-capitalista que, desde o século XIX, se apropria das práticas e imaginários associados às viagens. Nesses termos, o presente artigo segue estrutura teórico ensaística apoiada em revisão de literatura, propondo repensar o Turismo e, mais especificamente, o overtourism e a turismofobia, a partir da Geografia. Apoia-se para tal em Rogério Haesbaert e seu texto no livro “O mito da desterritorialização: do ‘fim dos territórios’ à multiterritorialidade”, ali buscando as teorizações do autor no que refere à questões associadas ao território. Reforçam-se as fortes interfaces do Turismo com o[s] território[s] e  encaminha-se que o overtourism e a turismofobia, mesmo que ainda não com esta denominação, já chamavam atenção acadêmica desde os anos 1960, em paralelo à expansão do dito Turismo de massa e a apropriação neocolonial dos territórios para fins turísticos, primeiramente na própria Europa para a seguir buscar territórios turistificáveis na periferia do capitalismo central, como América Latina e África.
A internacionalização do turismo e a dinâmica territorial no Arquipélago de Bazaruto em Moçambique
Authors: Vico Verónica Cecílio Chiundila , Azevedo Francisco Fransualdo de , Vico Roberto Paolo
Published: March 2022

Este artigo aborda acerca da racionalidade de diversos atores que são determinadas pelas relações de poder articuladas pelo processo de internacionalização do turismo. Também, diante do domínio de mercado turístico reflete-se sobre as atuações exógenas que exercem influência sobre a dinâmica do território do arquipélago de Bazaruto, assim como, sobre a lógica horizontal estabelecida por relações de vivência baseadas em laços de fortalecimento solidário. É neste contexto que, buscando materializar esta pesquisa de cunho qualitativo, com base na análise documental e bibliográfica, auxiliada da atividade em campo, interagiu-se com os sujeitos de pesquisa através da realização de entrevistas com membros da comunidade autóctone, empresários turísticos e funcionários da administração do Parque Nacional do Arquipélago de Bazaruto (PNAB). Também, realizou-se a observação direta e encontro participativo tendo em vista a apreensão das questões cotidianas do arquipélago de Bazaruto.  Por meio do contato que a comunidade tem com o contexto turístico, a comunidade passa a ter novas exigências e procura as facilidades da vida moderna. Contudo, enquanto a comunidade local se preocupa com a disposição de serviços e a aquisição de bens de consumo tidos como o mínimo para a subsistência, as firmas, mediante a atuação em rede, procuram atender a acumulação de capital pelos níveis de domínio tecnológico, da organização do trabalho e de capital, assim como de expansão de atividades, a exemplo daquelas ligadas ao turismo. A dinâmica territorial torna-se, no entanto, dependente e propícia à abertura de projeções exógenas que se fundamentam na lógica hegemônica de importação e difusão dos modelos de consumo.
A evolução do espaço turístico na “Geografia do Turismo”: Do reconhecimento ao desinteresse
Authors: Sampaio Ana Claudia Macedo
Published: March 2022

Desde o início do século XX a ciência geográfica colabora com a reflexão acerca do fenômeno do Turismo à sombra da intitulada “Geografia do turismo”, buscando compreende-lo em sua interação com espaço geográfico e seus desdobramentos, sem constituir um corpo teórico-metodológico consolidado que substancie o debate ou que incite a descoberta de outras perspectivas de análises. O reconhecimento do Turismo como uma área afim traz possibilidades de enriquecimento para a abordagem geográfica que permitem compreender o fenômeno turístico a partir de um novo olhar, além de ajudar a entender quais são os limites e as possibilidades dessa relação de troca. No contexto dessa problemática, compreende-se por fim que as análises geográficas prescindem de um aporte que ultrapassem a simples repetição de discursos produzidos no contexto do debate do espaço geográfico que não mais condizem com a atual necessidade de aprofundamento reflexivo em torno do turismo e da dinâmica globalizada do mundo pós-moderno.

Influence of temperature on the R-effect for the fatigue crack growth of nickel-base superalloy GH4169
Authors: Liu He , YANG Xiaoguang , Li Shaolin , Yan Cheng
Published: March 2022

The stress ratio ( R) effect, especially at elevated
temperatures, is associated with the fatigue crack growth (FCG)
prediction in aero-engine hot-end components under complex operation
conditions. The FCG experiments with three R were conducted on
Ni-based superalloy GH4169 at room temperature (RT), 550 °C, and 700 °C.
The results indicate that the R-effect on the FCG of GH4196 is
temperature-dependent. Therefore, efforts were made to identify the
R-effect at various temperatures to describe the FCG. The concept of the
crack-closure or the two-driving-force was examined to quantify the
R-effect considering the temperature influence. Fractographic analyses
on the fracture surface were performed to discuss the underlying
mechanism responsible for the temperature influence. The study can
contribute to the R-dependent FCG modeling at various temperatures.
Aprotic phosphonium-based ionic liquid as electrolyte for highly CO2 electroreduction to oxalate
Authors: Jiang Chongyang , Xifei Ma , Zeng Shaojuan , jiaqi Feng , Guilin Li , Bai Lu , Li fangfang , Ji Xiaoyan , Zhang Xiangping
Published: March 2022

In this study, a new electrolyte system consisting of
tetrabutylphosphonium 4-(methoxycarbonyl) phenol
([P4444][4-MF-PhO]) ionic liquid and acetonitrile (AcN) was
developed as CO2 electroreduction electrolyte to produce oxalate, and
the mechanism was studied. The results showed that using the new ionic
liquid-based electrolyte, the reduction system exhibits 93.8% Faradaic
efficiency and 12.6 mA cm-2 partial current density of oxalate at -2.6 V
(vs. Ag/Ag+). The formation rate of oxalate is 234.4 μmol cm-2 h-1,
which is better than that reported in the literature. The mechanism
study using density functional theory (DFT) calculation revealed for the
first time that [P4444][4-MF-PhO] IL can effectively activate
CO2 molecules through ester and phenoxy double active sites, stabilize
the reaction intermediate. The potential barriers of the key
intermediates *CO2- and *C2O42- formation by induced electric-field was
reduced in the phosphonium-based ionic environment, which greatly
facilitates the activation and conversion of CO2 molecules to oxalate.
Inhibition of endoplasmic reticulum stress and mitochondrial oxidative stress limits the development of abdominal aortic aneurysm and cardiac hypertrophy

Published: March 2022

Background and purpose: Persistent endoplasmic reticulum (ER) stress and
its deleterious crosstalk with mitochondria trigger oxidative stress,
mitochondrial dysfunction and inflammation contributing to the
pathophysiology of a myriad of cardiovascular diseases linked with
hypertension such as abdominal aortic aneurysm (AAA) and cardiac
hypertrophy. The purpose of this work was to determine whether
inhibition of ER and mitochondrial stress is effective preventing
aneurysm development and cardiac hypertrophy in angiotensin II
(AngII)-infused apolipoprotein-E-deficient (ApoE−/−) mice. Experimental
approach and results: The expression of ER stress markers (Hspa5, Atf4,
Atf6, Chop and Ern1) was up-regulated in aneurysmal abdominal aortas
from AngII-infused ApoE−/−mice. The treatment with ER stress inhibitors
improved survival, decreased systolic blood pressure, limited the
incidence and severity of AAA and reduced the AngII-induced increase of
aortic diameter evaluated by ultrasonography. These beneficial effects
were mimicked by the mitochondria-targeted tetrapeptide SS31. The
disorganisation of elastin and collagen fibres, the increased expression
of metalloproteinases and pro-inflammatory markers and the infiltration
of immune cells induced by AngII in the abdominal aorta were effectively
reduced by both, ER inhibitors and SS31. Additionally, treatment with
SS31 prevented the alteration of mitochondrial dysfunction and reduced
ER stress markers expression and plasmatic ROS levels. Mechanistically,
CHOP deficiency in ApoE−/−mice reduced the blood pressure and the
incidence of AAA. Interestingly, both pharmacological interventions and
CHOP deficiency attenuated AngII-induced cardiac hypertrophic
remodelling and improved systolic and diastolic function. Conclusions:
Our data evidence that inhibition of ER and mitochondrial stress limits
abdominal aortic aneurysm formation, increases survival and ameliorates
hypertensive cardiac hypertrophy.
PRODUCTION POTENTIAL OF THE VEGETABLE SECTOR IN POLAND AND SELECTED EU COUNTRIES
Authors: Filipiak Tadeusz , Olewnicki Dawid , Zaremba Łukasz
Published: March 2022

The aim of the research was to assess the production potential of the vegetable sector, as a factor of competitiveness, in Poland and selected EU countries. The evaluation of vegetable production was based on a comparative analysis of the level and changes in land area devoted to crops, yields, the number of farms and the average area of crops on the farm, the species structure of crops, the level of basic vegetable yields, and the resources of the factors of vegetable farm production from the FADN system. The research has shown that Poland’s high and growing position in vegetable production results mainly from the high acreage of crops, their partially complementary structure, and above all from relatively low labour costs compared to other surveyed EU countries. On the other hand, the improvement of effectiveness is not supported by the large fragmentation of Polish farms, although an increase in the average area of cultivation per farm was observed in the examined period. The research shows that in most of the analysed countries there was still a large fragmentation of vegetable farms. The analysis of vegetable farm inputs (on the basis of FADN data) in selected countries also shows that in the analysed period, a decrease in production factor resources was observed in Poland, Italy and France.
A THEORETICAL AND EMPIRICAL APPROACH TO FOREIGN LABOUR MIGRATION AND EMPLOYMENT: THE CASE OF AGRI-FOOD MIGRANT WORKERS IN DEVELOPED ECONOMIES
Authors: Zawojska Aldona , Siudek Tomasz
Published: March 2022

Most of the research on migration has focused on the scale and effects of people exodus from rural to urban areas rather than on rural areas as recipients of migrants, especially foreign migrants. This study aims to analyse employment of foreigners in agriculture and food processing sectors of selected developed countries, with particular emphasis on the time of the COVID-19 pandemic. It first reviews existing literature on ideas and theories about human migration through the history of economic and social thought. This theoretical background lies in the economic, social, health, demographic and integrated theories and concepts of migration that help understand the pull and push causes as well consequences of current international migration processes. Next, this article presents some facts about the employment of foreigners in agriculture and food processing in developed countries traditionally affected by severe labour shortages in these sectors, as well as the impact of the COVID-19 crisis on employers and workers. The results reveal that labour shortages and labour exploitation are amongst the most frequent and relatively consistent issues associated with immigrant workers in the agri-food industry. During COVID-19, these problems were exacerbated and complemented with the workers’ health risk due to coronavirus clusters on farms and at food-processing plants.

Selametan Day of the Dead From a Javanese Cultural Perspective among Santri and Abangan: a Case Study in Tulungagung District
Authors: Setyawan Bagus Wahyu , Aziz Abd. , Teguh Teguh , Jazeri M.
Published: March 2022

Selametan (communal feast) is tradition to commomerate one’s death day conducted by the Javanese community. Its implementation is different from one region to others. The study focused on describing and explaining the differences of selametan between santri and abangan community. It was a field study carried out in Tanen Village, Rejotangan District, Tulungagung Regency. The data were obtained by conducting an observation to the Tanen community. Besides, the data were also collected through interview and literature study. The results indicate that there are two versions of implementing the selametan tradition in Tanen Village. The abangan version still maintains traditions from the ancestors, in terms of using sesajen (offering) as a cultural symbol and means in a ritual. The time also remains the same as inherited from the ancestors, in which the ritual is conducted from the first day until nyewu dina or 1000 th day. The santri version only conducts the selametan tradition from the first until seventh days after the funeral and does not use sesajen considering its inappropriateness with Islamic lessons. Apart from these differences, the selametan tradition has positive functions, including a means to give alms, close the bound between community members, entertain a family of a deceased, and remember the death.

Authors: Bertossi Valeria , Gutiérrez María de los Milagros
Published: March 2022

Las prácticas ágiles surgieron como alternativa a las metodologías convencionales de desarrollo de software para lograr resultados más rápidos sin disminuir su calidad, otorgándole centralidad al factor humano que participa en el proceso y a los incrementos del producto en iteraciones muy cortas como fundamento para la generación de valor. Los objetos de aprendizaje, en cuanto productos de software cuya concepción y construcción demanda esfuerzo intelectual y creativo, y cuyo destino final se enmarca en el ámbito del conocimiento, son pasibles de capitalizar las ventajas de la agilidad. En este trabajo se presenta una revisión sistemática de la bibliografía referida a metodologías de desarrollo de objetos de aprendizaje con el propósito de detectar si están concebidas bajo el modelo de gestión ágil

Published: March 2022

El inicio de la pandemia provocó, entre otros efectos, una profunda transformación digital de los procesos de enseñanza-aprendizaje a nivel mundial. A partir de entonces, y como consecuencia de la obligada virtualización, el estudio de las habilidades digitales ha despertado un interés creciente. Por ello, la presente investigación se planteó analizar la producción científica iberoamericana en torno a las competencias digitales en tiempos de COVID-19 (2020-2021), publicada en 3 bases de datos (Scopus, Redalyc y Redib). Se obtuvieron 62 documentos que fueron analizados en base a un amplio conjunto de indicadores bibliométricos, como la producción temporal, el índice de producción por revista, el índice de coautoría, el país de filiación institucional, el idioma del documento, el tipo de estudio y el enfoque metodológico, entre otros. De acuerdo con los resultados, se produce una clara tendencia hacia los trabajos colaborativos, destacando como país productor España. Además, se aprecia una clara prevalencia de las investigaciones empíricas de carácter cuantitativo. Estas se dirigen, sobre todo, al estudio de las competencias digitales docentes, especialmente entre el profesorado universitario. El análisis realizado documenta la producción científica en este ámbito y sirve como referencia para futuras investigaciones centradas en programas de capacitación digital en Iberoamérica.

Published: March 2022

Se concibe a las prácticas mediadas por WhatsApp para el abordaje de textos literarios como una estrategia didáctica para la enseñanza del inglés en Brasil, y se las postula como objeto de análisis de la investigación que en este artículo se describe. El objeto se construye a través del estudio de caso de una escuela secundaria pública ubicada en Brasilia, mediante una metodología cualitativa y técnicas etnográficas de recolección y análisis de información. Los resultados evidencian que la disponibilidad que los alumnos tienen del teléfono celular y el fácil acceso a la web que permite el dispositivo para la realización de diversas tareas on line en simultáneo, potencia los beneficios de los textos literarios para el aprendizaje del inglés. La estrategia didáctica habilita usos creativos, heterogéneos y diversificados de WhatsApp y de los textos literarios cuando estos se combinan. No obstante, el uso de WhatsApp evidencia ciertos obstáculos que complejizan el proceso educativo. Dichos obstáculos son interpretados como desafíos por los participantes, quienes resuelven las actividades mediante las cuales se pone en práctica la estrategia didáctica. En las conclusiones, reflexivas y propositivas, se enuncia que la estrategia didáctica es compatible con el Método Comunicativo de enseñanza, realza el carácter flexible, lúdico y participativo del proceso de aprendizaje y su potencial para el desarrollo de competencias comunicacionales. Finalmente, se formulan 10 pautas para la realización de buenas prácticas mediadas por WhatsApp para el abordaje de textos literarios en la enseñanza del inglés en Brasil.

On the energetics of radical adduct formation of OH• with phenol analogs and aniline
Authors: Štellerová Dagmar , Lukeš Vladimír
Published: March 2022

Theoretical studies on aniline, phenol, benzenethiol, benzeneselenol, and their corresponding adducts with hydroxyl radical in possible positions on a hydrocarbon ring are presented. Bond dissociation enthalpies, related to radical scavenging of primary antioxidants, were calculated using the M06–2X/6–311+G** method. Calculated data were compared with available experimental data. Preferable homolytic bond dissociation of the presented molecules with OH• through functional groups X—OH followed by the m–OH ones has been confirmed. The highest antioxidant activity among the investigated positions is predicted for benzeneselenol. Also, the formation of non-covalent van der Waals structures has been shown as important in radical scavenging.
Behaviour of a Non-Newtonian Fluid in a Helical Tube Under the Influence of Thermal Buoyancy
Authors: Ramla Mohamed , Laidoudi Houssem , Bouzit Mohamed
Published: March 2022

This work is an evaluative study of heat transfer in the helical-type heat exchanger. The fluid used is non-Newtonian in nature and is defined by Oswald’s model. The work was performed numerically by solving each of the Navier–Stokes equations and the energy equation using the package ANSYS-CFX. Following are the aspects that have been dealt with in this paper: the effects of thermal buoyancy, fluid nature and the tube shape on the heat transfer, and the fluid comportment. The interpretation of the obtained results was done by analyzing the isotherms and the streamlines. The mean values of the Nusselt number were also obtained in terms of the studied parameters. The results of this research enabled us to arrive at the following conclusion: the intensity of thermal buoyancy and the nature of the fluid affect the heat transfer distribution but keep the overall rate of heat transfer the same.

The quest to reduce dangerous environmental emissions has led to the research and use of alternate and renewable energy sources. One of the major contributors to the dangerous environmental emissions is the automotive industry. The world is, therefore, quickly moving towards hybrid and electric vehicles. An alternate pollution-free automotive engine is a compressed-air engine, which is powered by compressed air and is more efficient than the electric engine since it requires less charging time than a traditional battery-operated engine. Furthermore, the tanks used in compressed-air engines have a longer lifespan in comparison to the batteries used in electric vehicles. However, extensive research is required to make this engine viable for commercial use. The current study is a step forward in this direction and shows the performance analysis of a single-cylinder compressed-air engine, developed from a four-stroke, single-cylinder, 70 cc gasoline engine. The results show that compressed-air engines are economic, environmental friendly and efficient.
