Reflections
Authors: Avery Mark
Published: March 2023

In this informed, incisive and passionate commentary on the state of nature and conservation, Mark Avery reflects on our relationship with the wildlife around us. From the cats that pass through his garden to the chronic decline of farmland wildlife, from the Pasqueflowers he visits every spring to the proportion of national income devoted to saving nature – everything is connected, and everything is considered. This book analyses what is wrong with certain ways we do wildlife conservation but explores some of its many successes too. How can we do better to restore wildlife to everybody’s lives? We know how to conserve species and habitats – it’s time to roll out conservation measures on a much bigger scale. This is a societal choice in which every nature lover can play their part. Reflections sets out what is needed, and what part the state, environmental charities and we as individuals can play in making that happen. This highly personal work from a life embedded in and dedicated to nature does not shy away from the harsh realities we face, but its message, ultimately, is one of hope.

Movilidad, espacio y diseño: metodología de análisis integrada del sistema viario en relación a sus contextos y a parámetros de diseño. El caso de la ciudad de la Plata
Authors: López María Julieta , Ravella Olga Rosa
Published: March 2023

En la última década los espacios del sistema de movilidad están siendo analizados desde nuevos enfoques. Enfoques que integran aproximaciones teóricas de diversas disciplinas y que avanzan sobre la tradicional concepción ingenieril de las infraestructuras. En línea con estos nuevos estudios, se expone una metodología que vincula dos escalas de análisis, la primera contextualiza al sistema viario para entender su rol en el sistema territorial que integra y la segunda detalla sus propiedades aplicando un sistema de parámetros de diseño, con el fin de comprender su incidencia en la movilidad, accesibilidad y habitabilidad urbana. El artículo propone como caso de aplicación para dicha metodología a la ciudad de La Plata, a partir de considerarla un caso representativo del conjunto de ciudades intermedias argentinas. Dichas ciudades han experimentado cambios importantes en su movilidad producto de la expansión urbana de las últimas décadas, sin el respaldo de instrumentos de gestión que contemplaran al sistema vial de manera integrada. Se presenta un repaso de la bibliografía más importante en materia de análisis y diseño urbano, profundizando detalladamente en la metodología propuesta, y evidenciando los resultados del caso. Se expone sintéticamente reflexiones sobre las escalas analíticas y los criterios clave que deben favorecer al diseño y organización del sistema viario.

Authors: León Aravena Javier , Núñez Cerda Francisco , Albornoz Del Valle Elias
Published: March 2023

La movilidad es un problema multifactorial. Entre sus aspectos figura la subjetividad de los ciudadanos, asociada a percepciones de los problemas que detectan, sensaciones y emociones que les provoca la experiencia de movilidad. Sin embargo, estos elementos, no son apropiadamente considerados en la formulación de los respectivos planes. La pregunta de investigación que se plantea es, si la participación además de identificar elementos objetivos para un plan, también lo puede hacer con los elementos subjetivos. El artículo describe cómo se exploraron e identificaron dichos aspectos para ser incluidos en la Formulación del Plan de Movilidad Sostenible para el Área Metropolitana de Concepción, Chile, realizado el año 2017. Se utilizó una metodología participativa implementada a través de talleres y encuestas aplicadas a informantes claves. Los datos fueron analizados de acuerdo triangulación metodológica y criterios de movilidad sostenible. Uno de los hallazgos destacados, es la funcionalidad y eficacia que la metodología participativa logra para identificar el papel de las emociones en la planificación. Otro hallazgo es la mención en un 70% de emociones negativas. Tal resultado, plantea la preocupación con relación a como se están llevando a cabo las actuales políticas y procedimientos de diseño e implementación de planes de movilidad, los que no consideran adecuadamente estos aspectos.

Tonsillitis, especially among hospitalized children, can cause worse impacts or complications. Dynamic, planned, and patient-centered nursing care is needed, which can be done by implementing discharge planning. This study aimed to analyze and evaluate the implementation of discharge planning among hospitalized children with tonsillitis. A case study method involving one patient and his family in the pediatric inpatient room; was carried out from April 3 to 6, 2022. The results of this study show that the implementation of discharge planning has been carried out following the theory. Discharge planning is carried out when the patient enters until the patient returns with stages assessment to evaluation; besides that, from the implementation of discharge planning, there is an increase in parents' knowledge about disease and skills about the importance of a healthy lifestyle and nutrition/dietary pattern in children. This study concludes that discharge planning is important in providing nursing care because it can increase independence, knowledge, and skills in healing and maintain the patient's health status. It was needed for a more detailed discharge planning assessment format because this study only includes studies that focus on tonsillitis patients and are linked to theory. If it is implemented on patients with different diagnoses, it is necessary to update the assessment format.

Entre a Pulsão de Morte e os Três Registros Lacanianos
Authors: Novelli Giovanni Vieira de Carvalho
Published: March 2023

Esse artigo visa demonstrar como o psicanalista francês Jacques Lacan delineou e reformulou o conceito freudiano de pulsão de morte no interior dos três registros da experiência humana. Dito isso, iremos inicialmente compreender de forma geral como o conceito de pulsão de morte aparece na obra lacaniana, de maneira a demonstrarmos como ela é reformulada pelo autor francês. Depois, iremos delinear como esse conceito aparece no interior dos registros do Imaginário, Simbólico e Real; desse modo, estaremos envoltos com o Estágio do Espelho desenvolvido por Lacan no decorrer dos anos 1930 e 1940, a teoria do significante fundada por nosso autor mais atentamente nos anos 1950 e por último o registro do Real, o qual foi introduzido com mais atenção a partir dos anos 1960 em diante.
A Fundamentação do Conceito de Ideologia de Žižek na Psicanálise de Lacan
Authors: Anhaia Allysson Alves
Published: March 2023

O conceito de ideologia em Slavoj Žižek tem como fundamento noções da psicanálise, sobretudo da teoria do discurso analítico de Jacques Lacan. Para o filósofo, a ideologia funciona como uma máscara social, como uma fantasia que age nos níveis do imaginário e do simbólico de maneira que molda a realidade dos sujeitos e os distância do encontro traumático com o real. Desta forma, o objeto deste artigo é demostrar como se dá a fundamentação do conceito zizekiano de ideologia na psicanálise de Jacque Lacan com o objetivo de explicitar as influências e implicações da ideologia na contemporaneidade. A partir desta compreensão a respeito da noção de ideologia é possível analisar como se dá a atividade das diferentes ideologias nas sociedades atuais, bem como a influência delas nas relações interpessoais, na subjetividade dos sujeitos contemporâneos, de modo que a crítica a ideologia seja mais pertinente e voltada para a contemporaneidade.

DETERMINATION OF A SIMPLE AND ROBUST METHOD TO CALCULATE IGNITION DELAY IN COMPRESSION IGNITION ENGINES: APPLICATION TO DIESEL-BIODIESEL-ETHANOL BLENDS
Authors: Bret P. , Pradelle F.
Published: March 2023

Today, the automobile industry is under increasing pressure from governments and environmental organizations to lower their carbon footprint. Car manufacturers release new models that follow modern and severe norms of pollutant emissions using eco-friendly technologies. Their strategy follows two main pathways: decarbonization and increase of efficiency. In order to achieve the aforementioned objective, the replacement of fossil fuels with renewable biofuels with lower carbon footprints, such as biodiesel and/or ethanol, contribute to the decarbonization of current internal combustion engines. However, changes in the fuel composition also imply some adjustments in the injection and combustion settings to optimize the engine operation. An important parameter to assess the combustion process in a compression ignition (CI) engine is the ignition delay (ID), defined as the duration between the start of fuel injection (SOI) and the start of combustion (SOC). Different direct and indirect approaches are reported in the literature to measure or calculate the ID. This study investigates two indirect methods based on the measurement of the indicated pressure inside the combustion chamber, throughout the displacement of the piston. These measurements are based on the position of the maximum of the third-order derivative of pressure as a function of the crank angle and the subjective shift from a polytropic compression process, respectively. The objective of the present work is to define an objective criterion to quantify this shift in order to allow a unique determination of the ID, independently of the adopted method. Thus, data of six different fuel blends of diesel-biodiesel-ethanol in a four-stroke CI engine from tests performed at PUC Rio’s Vehicular Engineering Laboratory for different loads and engine speeds were analyzed using the software Matlab. As observed in previous literature, the results show that the addition of biodiesel and ethanol concentration in the blends slightly increases the ID. Moreover, the difference between the experimental pressure with combustion and the calculated pressure in the polytropic compression process at the SOC position is lower as engine load increases and/or engine speed decreases and seems independent of the fuel blend composition. Nonetheless, the variation of the pressure difference at the SOC stays moderate, allowing the determination of a unique value to directly read the ID from the indicated pressure profile, without requiring the smoothing process of the third-order derivative of the pressure.

Published: March 2023

Modern population’s needs increased demands for electricity in such a way that new energy sources were explored, in search of lower environment impacts and fossil fuels dependency. Renewable energy sources for electricity production, such as solar and wind energy, have significantly attracted attention and places as the west region of Bahia state has a good potential for its application. This location is characterized by high solar irradiance of 2136 kWh/m² a year, already having 4 photovoltaic power plants in operation and 2 more in project phases. Another possible application is the solar thermal energy and Kalina Cycle presents as a good possibility for employing it, since the non-azeotropic mixture of ammonia-water as working fluid allows low temperature heat sources utilization. Based on that, this research proposed the study of a Kalina power cycle, with steady state conditions, using thermal solar energy as low temperature heat source and applied to the solar irradiance of Bom Jesus da Lapa – BA. The thermodynamic cycle was developed and simulated with Engineering Equation Solver (EES®), thermal efficiency was analyzed by varying parameters such as: heat source temperature from 90 °C to 120 °C, high pressure line from 10 to 35 bar and ammonia mass fraction from 0.35 to 0.95. The final cycle presented a superheater before the turbine and a regenerator with poor ammonia-water mixture from the separator (as hot side) and ammonia-water mixture before entering the boiler (as cold side). Results indicated maximum efficiency of ~7.4%, with high pressure side of 35 bar, heat source temperature of 120 °C, superheater heat source temperature of 200 °C and ammonia mass fraction of 0.64 kg/kg.

The editorial of Thermal Engineering of this issue continues the discussion on scientific research needs in vital areas in which thermal engineering has important participation. The main goal is to motivate the readers, within their specialties, to identify possible subjects for their future research. Our modern life would not be possible without electricity and the fuels used in transportation and equipment that bring the so appreciated comfort to the sociedy. Energy is crucial for the development and progress of nations to the point where the level of development of a country is estimated qualitatively by its energy consumption. In these contexts, along with the threat of lack of fossil fuel for the future and the worldwide debate about environemntal impacts, humanity is presented the hard question about how to generate clean energy in a sustainable way facing the estimation that by 2050 the demand of energy will double the demand of the beginning of the century. Oil is the most used fuel nowadays. Its excessive use, however, can birng consequences as for example, its complete depletion and the negative environmental impacts due to the gases generated by its combustion. The International Panel on Climate Change (IPCC) established the goal of stabilizing the level of CO2 concentration below 500 ppm and to limit the increase of the global temperature to 2oC above the pre-industial levels. Taking into consideration the increase need of energy and the relevany of environamental impact matters, renewable energy has been considered an attractive option. It replaces fossil fuels and the tehcnology used for its generation has been substantilly improved in years. Among the most viable sources of renewable energy (solar, wind, thermal, nuclear), bionergy is the one that has the possibility to use the big spetrum of organic substacts (including toxic waste) while at the same time fixes the carbon. Algae is one of those examples. A large range of biofuels as for example, biogas, biohydrogen, biomehtane, biodiesel, bioethanol and biocoal, can be obtained from algae biomass.    The mission of Thermal Engineering is to document the scientific progress in areas related to thermal engineering (e.g., energy, oil and renewable fuels). We are confident that we will continue to receive articles’ submissions that contribute to the progress of science.

Published: March 2023

The main goal of this work is to investigate how the angles of a convergent-divergent rocket nozzle influence the thrust curve of a solid-propulsion rocket. The work has been conducted within an academic rocketry team. As there is not clear reasoning on how to define these angles, the present research provides insights on how these geometrical parameters influence the performance of a rocket motor. A 2D-axisymmetric CFD domain is considered, comprising the fluid domain inside and outside the nozzle, to give room for the shock waves to happen and also accommodate the flow. The study comprises a baseline geometry and twelve modified designs, varying the convergent and the divergent angles of the nozzle. Since the convergent diameter must match the chamber diameter, it is fixed. For the divergent diameter, there is no such restriction; therefore, there are two possibilities: a divergent section with the same divergent diameter or with the same length as the baseline. The benchmark thrust curve is generated with a MATLAB code based on solid-fuel modeling and the De Laval theory. The curve is divided into six steady-state simulations, using boundary conditions of mass flow, pressure and temperature at the inlet and pressure and temperature at the outlet. The baseline geometry is simulated in Ansys Fluent and normalized by the MATLAB benchmark. A mesh study selects which mesh and turbulence model to use based on this normalization. The modified geometries are then compared to the baseline. The main quantity of interest is the thrust but quantities such as static pressure and average velocity at the nozzle exit aid the understanding of the changes in thrust.

Algae are ubiquitous organisms whose capabilities have drawn much attention as of late in the bioengineering field due to their potential to enable a wide range of bioproducts. Microalgae are ideal organisms for the application of the biorefinery concept since they can be grown in wastewater and, at the same time, produce many products of commercial interest. These microorganisms are also known for their resilience to extreme environmental conditions and suitable cell growth rates. Beyond the known potential for biofuel production, these microorganisms can still produce other compounds, being lipids, pigments, vitamins, proteins, and polysaccharides, whose applications go from pharmaceutical to agricultural industries. Recently, the research focus has been directed to the biopolymer-producing ability of both micro- and macroalgae, as they can be rather varied and useful to many applications. However, this is still an ongoing research field, and new data are frequently added in the literature, notably on biomass processing, which can be done with the intent of use into dyes, bioplastics, paints, and even as biochar in solid fuel cells. Microalgae-based biopolymers can be used in a wide range of products, nevertheless, the resulting process efficiency and yields depend on the extraction process utilized, as well as on the microalgae species used and the culture conditions. Furthermore, the polymer extraction can be done directly with common solvents at atmospheric pressure or with other fluids, such as supercritical CO2 or subcritical solvents, and assisted by specific treatments, e.g., ultrasound and microwave. The residual biomass can still be used to produce other less valuable products, such as feedstock, and energy via combustion. In this sense, the present work aims to provide a state-of-the-art review on microalgae biopolymers. Issues related to the efficiency of current treatment methods, industrial applications, and environmental performance are presented and discussed. Besides, the perspectives in this area of knowledge are also a contribution of the present work, the extent to which scientific research is still under development.

Published: March 2023

In order to reduce oil dependency and reduce CO2 emissions stabilizing the greenhouse effect on the planet, the search for new renewable energy sources has been intensified, with a particular interest in hydrogen based solutions. Hydrogen can be used in fuel cells, which have several applications. Fuel Cells are among the environmentally friendly energy conversion systems for the 21st century with simple components such as membrane, catalyst, rearrangeable configurations that allow them to accommodate space limitations, and their use of hydrogen and oxygen. There are many types of fuel cells that are distinguished by the electrolyte type and their operating temperature. Alkaline Membrane Fuel Cells (AMFCs) and Proton-Exchange Membrane Fuel Cells (PEMFCs) are major types that work in low temperatures and produce only H2O and electricity as part of the electrochemical reaction. AMFC is a fuel cell that has more affordable membranes, when compared to the PEMFC that uses a polymeric membrane with high cost, making applications more expensive. In AMFCs, the alkaline membrane used, is a simple filter paper saturated with KOH solution that allows ions to pass through the membrane, however, suffers CO2 poisoning when it gets in contact to the carbon dioxide present in the air, reacting in the KOH and capturing hydroxyl ions. The poisoning will generate chemical compounds that will interfere with the energy generation and efficiency of the fuel cell. The main cause of the decreasing performance of carbonate formation is the precipitation of large metal carbonate crystals such as K2CO3 and the formation of H2O in the membrane, decreasing KOH concentration. If not addressed, this issue will limit the use of AMFC to pure oxygen applications only, instead of the air itself, which restricts the applicability of the technology. This study presents a mathematical model of a purifier that reduces the concentration of CO2 present in the air, improving conditions to be used in AMFC for mobile applications as automotive vehicles and without the need to use pure oxygen.

Published: March 2023

Plant extract (Lantana camara) and earthworm (Pheretima posthuma) extract have been used to treat many illnesses for centuries; they have been reported to suppress the growth of many pathogenic bacteria and are specially used for wound healing. We analyzed the antibacterial activity of the different organic extracts obtained from these species against pathogenic strains of bacteria and compared them to know which is more potent for developing antiseptic ointment. Ethanol and acetone solvents were used for the extraction and analyzed for their antibacterial activity by the disk diffusion and shake flask test. Then we identified the minimum inhibitory concentration of extracts against gram-positive and gram-negative strains. Lantana camara showed the largest growth inhibitory zone against Pseudomonas aeruginosa, followed by Serratia marcescens, and Staphylococcus aureus. MIC for plant extract was 150μg/ml, while earthworm extract inhibited growth at a minimum dose of 200μg/ml. We found that the plant's ethanol extract (L. camara) exhibited robust antimicrobial activity compared to the worm extract. Current investigation reinforces the application of Lantana camara extract to develop ointment to treat wound infections.

The most effective systemic therapy for acne is Isotretinoin. However, Isotretinoin has many side effects, including known side effects like dryness, palmoplantar exfoliation, rash, teratogenicity, raised intraocular pressure, and deranged liver functions and lipid profile. Its lesser-known side effects include its effects on platelet count and mean platelet volume (M.P.V.). This Quasi-experimental case series was conducted to observe the change in platelet count and mean platelet volume in patients taking Isotretinoin for acne vulgaris, attending the dermatology outpatient department at Jinnah Hospital Lahore from May 10th 2016 to November 9th 2016. After ethical committee approval and informed consent, subjects of acne vulgaris with an indication for Isotretinoin were included in the study from O.P.D. Relevant demographic and clinical details were recorded in a standardized predesigned proforma. Citrated blood samples were taken under aseptic conditions. Baseline platelet counts and mean platelet volume were determined using an auto-analyzer in the pathology laboratory of Jinnah hospital Lahore. All the patients were advised to take daily Isotretinoin at a dose of 0.5 mg/kg for 12 weeks. Platelet counts and mean platelet volume were again measured after twelve weeks after the start of treatment. A total of 100 patients completed the study. The age of the patients ranged from 18 to 60 years with a mean + sd age of 27.26+5.88 years. Out of these 41%(n=41) were male and 59%(n=59) were females. The severity of acne was measured using Global Acne Grading System (G.A.G.S.). It was recorded that 62%(n=62) had moderate, 22%(n=22) had severe while 16%(n=16) had very severe acne vulgaris. The mean pre-treatment platelet count was 271273+9139 c/µL, while 259192+11717 c/µL was post-treatment. The mean difference was 12080+8140 c/µL, and the p-value was 0.001. The mean platelet volume was 10.63+1.01 fl as pre-treatment and 9.77+1.01 fl as post-treatment. The mean difference was 0.85+0.04 fl, and the p value was 0.001. We concluded that Isotretinoin decreases platelet count and means platelet volume in patients receiving isotretinoin treatment for acne vulgaris.

Background: Osteoporosis, demonstrated as an associated disease with more than 30 gene disorders, is a polygenic disorder, and it’s also implicated in bone mineral density (BMD) regulations. Lipid peroxidation and hydrogen peroxide levels significantly increased and vice versa the antioxidant enzymes decreased such as Glutathione S-Reductase GSR was found in female postmenopausal females. Objective: This research was done in order to find out the effect of rs2978663 genotypes on the progression of osteoporosis. Methods: First, blood samples were used to extract DNA for analysis. Molecular examination was achieved using PCR, RFLP, and UV imaging after electrophoresis in an agarose gel, and these results were analyzed by SPSS (version 23). Results: The genotypes differed in healthy people, and the proportions varied, as they were: the highest percentage was represented by the GA genotype (78%), followed by the AA genotype (16%), and the GG genotype (6%). For case samples, the highest percentage was represented by the GA genotype (51%), followed by the AA genotype (30%), and the GG genotype (19%). There are significant associations between GA genotype and restriction of fragility disease. The risk of having osteoporosis was significantly lower in those with the GA genotype (OR = 0.1946; 95% CI = 0.04-0.95; P = 0.03). The A allele frequency of the GSR gene (rs2978663) did not change significantly between study groups (OR: 0.9965, 95% CI: 0.5547-1.7816, P value: 0.9905). Conclusion: Overall, it is safe to say that GSR-int3 (rs-2678663) was shown to have no association with osteoporosis in this research of Iraqi women. Inherent variation in the GSR gene (rs-2678663) is associated with decreased osteoporosis risk.

Various statistical techniques exist in statistics for the analysis and interpretation of the data. The awareness of assumptions and circumstances governing each statistical method is crucial for selecting the best method for data analysis. The purpose of the study, the type of data, and the measurements (paired or unpaired) are the three aspects to decide the most appropriate statistical method. Statistical procedures that compare means are known as parametric methods, and those statistical techniques that reach median, mean ranks, or proportions are known as nonparametric techniques. The current review aims to help the reader understand the assumptions underlying both parametric and non-parametric statistical approaches and to choose the best ones for the analysis and interpretation of biomedical data.
