Polypropylene-based composites reinforced with waste tropic wood flours: Determination of accelerated weathering resistance, tribological, and thermal properties
Authors: Basboga İbrahim Halil
Published: September 2023

This study investigated the effects of Iroko wood flour (WF) and nano-titanium dioxide (TiO2) concentration on the properties of polypropylene (PP)-based composites, including accelerated weathering resistance, tribological behavior, thermal stability, physical characteristics, mechanical strength, morphological features, color changes, and surface roughness. The results showed that the presence of WF and TiO2 significantly influenced the density, hardness, thermal stability, crystallinity, coefficient of friction, and wear rate of the composites. Both fillers positively impacted the tensile strength, flexural strength, and flexural modulus of the composites, although the elongation at break values decreased. TiO2 addition enhanced thermal stability and protection against UV radiation, whereas using wood flour negatively affected color properties. Moreover, the surface roughness of the composites was affected by weathering time and wood flour content. These findings highlight the potential of WF and TiO2 as effective fillers for enhancing PP-based composites’ properties and weathering resistance.
Comparación del desempeño económico entre empresas industriales alimentarias certificadas y no certificadas con la norma ISO 9001
Authors: Aravena Andrade Amanda Victoria , Vega Oliveros Tamara
Published: September 2023

Only a small group of companies in Peru are certified to the ISO 9001 International Quality Standard, and it is uncertain whether this standard contributes to their financial performance. As a result, the objective of this study was to compare the financial performance of food manufacturing companies certified to ISO 9001 with those that are not. The non-parametric Mann-Whitney U test for median comparison was applied, since the data analyzed did not follow a normal distribution. It was found that there is no statistically significant difference between the financial results of the two groups; however, referring specifically to the asset turnover indicator, companies that have adopted the guidelines of the International Quality Standard, on average, convert their assets into cash more frequently.

Published: September 2023

La mejora de las Unidades de Producción Agropecuaria (UPA) en Ecuador depende del conocimiento de las necesidades de los ganaderos para el planteamiento de alternativas adecuadas y transferencia de tecnología. El presente trabajo tuvo como objetivo identificar los componentes del sistema de producción de bovinos doble propósito en dos cantones de la provincia Zamora Chinchipe. Se aplicó una entrevista a 30 ganaderos del cantón Nangaritza y a 65 de Palanda, con un cuestionario que consideró aspectos sociales, técnicos y económicos. En ambos cantones predomina la mano de obra familiar y la mayoría cuenta con terreno propio. El 53 y 73% de las UPA de Nangaritza y Palanda, respectivamente, tienen entre 5 a 50 ha, donde cultivan mayormente el pasto Merkeron (Setaria sphacelata). El número de cabezas promedio por UPS es de 43 y 37 en los cantones de Nangaritza y Palanda, respectivamente. En el aspecto económico, los productos pecuarios son vendidos fuera de la UPA y los ganaderos financian sus actividades con créditos del Banco del Estado. Se concluye que la ganadería bovina en ambos cantones se basa en sistemas extensivos, donde si bien existe asistencia técnica, aún se observan deficiencias que podrían ser mejoradas si se implementan tecnologías acordes a las particularidades de los ganaderos.

El estudio determina la prevalencia de trematodos mediante coproparasitología en ganado vacuno lechero de crianza al pastoreo en seis distritos de la región Cajamarca. Los análisis y procesamiento de las muestras fecales se realizaron mediante sedimentación natural. La proporción de animales parasitados fue de 50.4±2.1% (1092/2169), de Fasciola hepatica de 32.4±2.0% (703/2169) y Calicophoron microbothrioides de 17.9±1.6% (389/2169), en tanto que la coinfección por ambos parásitos fue de 7.51±1.11% (163/2169). Las prevalencias por distrito fueron en Cajamarca de 49.5±5.0% (188/380), Baños del Inca 61.2±5.6% (181/296), La Encañada 80.7±4.1% (284/352), Celendín 45.4±5.0% (171/377), San Juan 50.0±5.0% (190/380) y Chota 20.3±4.0% (78/384). No hubo asociación estadística en la presentación de ambos trematodos en los animales (p>0.95), ni se encontró correlación entre la altitud de cada distrito y la presencia de huevos fecales (r=0.19). Se concluye que, la prevalencia de trematodos en ganado vacuno lechero de crianza extensiva en Cajamarca es alta, con mayor presencia de F. hepatica, seguido de C. microbothrioides y su coexistencia.

Published: September 2023

El objetivo del estudio fue inactivar microorganismos patógenos mediante el proceso de compostaje durante 120 horas utilizando residuos de compuestos orgánicos en dos proporciones: C/N 25 compuesto por 25.31, 40.42 y 34.27% y C/N 35 por 44.61, 12.90 y 42.50% de paja de frijol, forraje fresco de sorgo y estiércol seco, respectivamente. Las variables analizadas fueron temperatura, carga microbiana (aeróbicos mesófilos, coliformes totales y fecales) y reducción de Escherichia coli y Salmonella Typhimurium inoculadas artificialmente en tres niveles de las pilas de compost. El tratamiento C/N 35 alcanzó la mayor temperatura e inactivación de los microorganismos patógenos evaluados durante la fase termofílica del compostaje. Las temperaturas alcanzadas no fueron homogéneas entre los niveles de las pilas siendo inferior en el nivel superior (p<0.000). Este estudio sugiere la implementación del compostaje como una alternativa eficiente para la disposición de residuos avícolas.

Published: September 2023

El objetivo del estudio fue evaluar el tiempo de inducción y de recuperación de Dormitator. latifrons mantenidos en agua dulce y salobre, expuestos a cuatro dosis de eugenol. Un total de 240 organismos fueron transferidos individualmente a un acuario con 15 L de agua dulce (0 UPS) o agua salobre (20 UPS) con la dosis de eugenol de cada tratamiento (42.5, 85, 170 y 255 mg/L). En cada tratamiento se analizaron 30 peces. El tiempo de inducción no mostró diferencias significativas entre niveles de salinidad, en tanto que el tiempo de recuperación fue significativamente mayor en agua salobre (706 s) que en agua dulce (507 s) (p<0.05). En ambas salinidades, el incremento de la dosis de eugenol disminuye el tiempo de inducción e incrementa el tiempo de recuperación. Los resultados indican que la dosis eficaz de eugenol para D. latifrons es de 170 mg/L en ambas salinidades; sin embargo, para procedimientos de corta duración sería suficiente una inmersión en una dosis de 42.5 mg/L para lograr una sedación.

El objetivo del estudio fue establecer la relación entre el nivel de tecnificación y la calidad de la leche en establos lecheros de la provincia de Lima, Perú. El estudio se llevó a cabo en 18 establos. Se recolectaron datos a través de encuestas, así como análisis de muestras de leche colectada durante tres días consecutivos. Se evaluaron variables relacionadas con el nivel de tecnificación de los establos, así como la calidad física, composicional, higiénica y sanitaria de la leche. Los resultados revelaron puntuaciones promedio de tecnificación de 7.1/10 en manejo, 4.3/10 en instalaciones y recursos, 4.2/6 en el ordeño, y 15.6/26 en tecnificación global. En cuanto a la calidad de la leche, se registraron temperaturas promedio de 18.38 °C, pH de 6.60, densidad media de 1.030 g/mL, sólidos totales de 12.11%, y grasa de 3.46%. El conteo promedio de bacterias mesófilas fue de 210x106, coliformes de 6x107, y células somáticas de 300x105 cél/mL. Se encontraron correlaciones negativas significativas entre el nivel de tecnificación con la temperatura de almacenamiento, el puntaje de sedimentación, y el conteo de bacterias mesófilas y coliformes en la leche. Además, quedó evidente que los establos con mayor nivel de tecnificación presentaron parámetros de calidad de la leche significativamente mejores en comparación con aquellos con menor tecnificación.

Published: September 2023

Los microplásticos (MP) han sido registrados en los ecosistemas marinos alrededor del mundo; sin embargo, poco se conoce sobre la variación temporal y espacial de los MP en playas marinas de Perú. En este trabajo se evaluaron los MP en Emerita analoga (Crustacea: Hippidae) y en los sedimentos de ocho playas arenosas, al norte y sur de la ciudad de Lima, en dos temporadas. Se colectaron 30 individuos de E. analoga y muestras de sedimento de cada una de las ocho playas por cada temporada (invierno y verano). Los MP fueron extraídos, contabilizados y caracterizados. Se observó una abundancia de 0.02 ± 0.13 a 1.82 ± 6.31 items de MP/individuo en E. analoga y en los sedimentos variaron de 41 ± 31.07 a 5353 ± 4013 ítems de MP/kg. Los fragmentos fueron el tipo predominante en los sedimentos, mientras que las fibras lo fueron en E. analoga. El transparente fue el color más frecuente. Los tamaños de las partículas en el sedimento oscilaron principalmente entre 1000 y 3000 µm, y en E. analoga fueron menores a 1000 µm. Se puede afirmar que la variación espacio-temporal juega un rol más importante en la dinámica de los MP en sedimentos en comparación con E. analoga. La abundancia de MP en el sedimento de la playa no guardó relación con la proporción de los individuos en E. analoga que los ingirieron, ni con la cantidad ingerida.
Study on the perception of generation Z in relation to robotized selection processes
Authors: de Barros Neto João Pinheiro , de Oliveira Lucas Pereira
Published: September 2023

Born in the mid-1990s, Generation Z emerged in the midst of a society whose advances in digital and technological media have been shaping the way companies act, especially in hiring people. This is an emerging generation, and studies and research on it are incipient. The aim of this study was to identify and analyze the perception of Generation Z regarding the robotization of selection processes and the application of artificial intelligence. The study used a survey with online questionnaires addressing how Generation Z has behaved in robotic selection processes. Contradicting what is disclosed in the media in general, a representative part of the sample is reticent in accepting a robotic selection process conducted by artificial intelligence as a mediator; besides that, there is a certain distrust with personal data made available technologically, as there are several platforms that adhere to this technology as a method of filtering suitable candidates for a given vacancy. Although the research had a reduced number of respondents (108) and a sample of only one program from a single university, which is a limitation of the study, the analyses of the results indicate the need for companies to review the use of artificial intelligence to ensure greater humanization, starting from the selection process in organizations. Furthermore, the data reveal that Generation Z may not represent a group of people with a completely homogeneous profile as shown by the media in general.

Obesity is a complex metabolic disorder that can be followed by blood coagulation disorders, athero­sclerosis and atherothrombosis. In the present work, the levels of fibrinogen, soluble fibrin, D-dimer as well as protein C were measured in the blood plasma of 24 morbidly obese patients (the body mass index exceeds 40 kg/m2) to evaluate the risk of prothrombotic state. The study showed that near by 80% of patients had substantially increased fibrinogen concentration, 33% had increased concentration of soluble fibrin, 42% had increased level of D-dimer in blood plasma as compared to control. According to the results of individual analysis, the high level of fibrinogen and soluble fibrin while reduced protein C indicated the threat of thrombosis, which requires complex diagnostics to be identified. Therefore, simultaneous quantification of hemostatic system biomarkers in the blood plasma is the confident way to predict the risk of thrombotic complications in morbidly obese patients. Keywords: D-dimer, hemostasis, obesity, protein C, soluble fibrin, thrombosis

The effect of concomitant pesticides and plant growth regulators on humans is still not well understood. N-oxide-2,6-dimethylpyridine (Ivin) is the plant growth regulator known to reduce the acute toxicity of pesticides, but its protective mechanisms need to be investigated. The aim of the study was to assess the hepatoprotective ability of 2,6-dimethylpyridine N-oxide (Ivin) using a model of acute CCl4-induced hepatitis. Male Wistar Han rats received two subcutaneous CCl4 injections (0.8 ml/100 g b.w.). Oral Ivin (13 or 0.13 mg/kg) and hepatoprotector “Silybor-35” (5 mg/kg) as reference substances were administered orally one hour pre- and 2 hours post-CCl4 injection. The biochemical assay of blood plasma, estimation of lipid peroxidation products in the liver tissue and histological liver analysis were done. The results of functional tests and histomorphological studies of liver tissue demonstrated that Ivin exhibited a pronounced hepatoprotective effect, more pronounced when it was administered at a low 0.13 mg/kg dose. Calculation of the hepatoprotection efficiency index for Ivin showed that it was comparable to that for “Silybor-35”. Keywords: hepatoprotective effect, Ivin, СCl4-induced hepatitis of rats
Support for the Use of a New Cutoff to Define a Positive Urine Culture in Young Children
Authors: Shaikh Nader , Lee Sojin , Krumbeck Janina A. , Kurs-Lasky Marcia
Published: September 2023

BACKGROUND

Conventional urine culture selects for a narrow range of organisms that grow well in aerobic conditions. In contrast, examination of bacterial gene sequences in the urine provides a relatively unbiased evaluation of the organisms present. Thus, by using 16S ribosomal ribonucleic acid (rRNA) gene amplicon sequencing as the reference standard, we now have the ability to assess the accuracy of urine culture in diagnosing urinary tract infection (UTI).

METHODS

We enrolled febrile children 1 month to 3 years of age that underwent bladder catheterization for suspected UTI. Using 16S rRNA gene amplicon sequencing as the reference standard, we calculated the accuracy of urine culture at various cutoffs (10 000, 50 000, and 100 000 colony forming units per milliliter). Children with ≥80% relative abundance of any organism on 16S rRNA gene amplicon sequencing with elevated urinary markers of inflammation were defined as having a UTI.

RESULTS

When using a cutoff of 10 000 CFU/mL, the sensitivity and specificity of urine culture were 98% (95% confidence interval [CI]: 93%–100%) and 99% (95% CI: 97%–100%), respectively. Using a cutoff of 50 000 colony forming units per mL decreased sensitivity to 80% (95% CI: 68%–93%) without changing the specificity. Using a cutoff of 100 000 further decreased sensitivity to 70% (95% CI: 55%–84%).

CONCLUSIONS

Conventional culture remains an accurate method of diagnosing UTIs in young children; however, these data suggest that a cutoff of 10 000 colony forming units per mL provides the optimal balance between sensitivity and specificity for children undergoing bladder catheterization.
Analgesic use among residents of youth sociotherapy centres and youth correctional centres
Authors: Pisarska Agnieszka
Published: September 2023

Introduction and aim: International and national studies indicate that analgesic use is common among adolescents. Research projects on this issue in Poland to date have been conducted among youth attending mainstream schools. However, data on the analgesic use among adolescents attending special education institutions, i.e. youth sociotherapy centres (młodzieżowe ośrodki socjoterapii, MOS) and youth correctional centres (młodzieżowe ośrodki wychowawcze, MOW) is missing. The aim of this study was to assess the prevalence of analgesic use among youth attending special education centres. Materials and methods: The study was conducted in 2018 among youth aged 12–19 years from randomly selected MOS/MOW facilities in Poland (N = 1,730). Data was collected with a self-administered questionnaire. A chi-square test was used to assess differences in analgesic consumption rate by gender and facility type. Results: Approximately 60% and 44.5% of study participants used analgesics for headache and stomach-ache, respectively, at least 1–2 times in the past month. Girls are significantly more likely than boys to use medications for headache and stomach-ache. The analgesic consumption rate among MOS/MOW youth is higher than among adolescents attending mainstream schools. Conclusions: Due to the risk associated with medicine use preventive measures addressing youth should include activities aimed at improving knowledge and skills regarding safe medication use. A history of analgesic use by an adolescent should be part of a family doctor’s routine interview.
Epiglottic mass mimicking laryngeal carcinoma: a red herring
Authors: Velayutham Jeeven , Saniasiaya Jeyasakthy
Published: September 2023

Aim: Laryngeal masses are commonly found during patient assessments in the otorhinolaryngology clinic and are almost always associated with a serious pathology, such as a malignancy, rather than a benign condition. In addition, epiglottic masses are often linked to a malignant disorder or granulomatous infection. Case report: Herein, we describe an immunocompromised patient presenting with respiratory distress secondary to an epiglottic mass requiring tracheostomy in view of airway compromise. A repeated histopathological examination revealed methicillin-resistant Staphylococcus aureus, which was successfully eradicated with long-term antibiotics. The tracheostomy was decannulated. Conclusion: We highlight the importance of early measures and interventions to obtain a diagnosis that will aid in patients’ management and recovery.

Authors: Fechner Joanna , Markowska Anna
Published: September 2023

A patient with secondary infertility, diagnosed with an endometrial polyp and right ovarian cyst, was referred for hysterolaparoscopy treatment. The woman reported no symptoms. During the hospitalisation, in addition to the aforementioned issues, left ovarian lesions and ascites were identified. A 10 cm lesion in the right ovary exhibited abundant vascularity. Tumour markers (AFP, CEA, HE4, CA-125) and the ROMA algorithm were assessed and found to be within the normal range. Laparotomy revealed a high-grade malignant tumour of unknown origin confirmed by histological examination. Uterine resection with unchanged greater omentum was performed. Immunohistochemical tests revealed positive cytokeratin (CK) reaction, including CK7 and focal CK20, as well as a marker of proliferation Ki-67 in some cells (20–30%). Signet ring cells and positive mucicarmine stain reaction were detected. The histological evaluation confirmed a Krukenberg tumour originating most likely from the stomach. The patient was referred to the Maria Skłodowska-Curie Greater Poland Cancer for further treatment.
From 20th century weddings to quarantine weddings: Old and new approaches to analyzing rituals
Authors: Balatonyi Judit
Published: September 2023

Although ethnographic studies of marriage in 20th century Hungary have reckoned with the impact of socio-cultural transformations on getting married, nonetheless they primarily emphasized the normative aspects and permanence of the ritual; they stressed that marriage preserved “traditions”, or even that folk tradition acting as an ethno-folk-national “matrix” preserved and maintained the wedding rituals. Even if they touched upon the transformation of rituals, they primarily highlighted the modernization, simplification, fragmentation of the act of getting married and the marginalization of original meanings, traditional community norms, ideologies, and roles. Could this static and normative image depicting marriage not as a changing but rather as a decaying, diminished institution be in fact the result and consequence of an epistemological tradition, a methodological-theoretical focus that hides the process of the emergence of a new conception of marriage based on free choice, improvisation and on the idea of the individual breaking free of the yoke of normative traditions? The purpose of my paper is twofold. I will examine what the earlier Hungarian ethnographic studies understood by constancy, normativity, traditional or modern of wedding rituals. On the other hand, based on my current anthropological research (2019-2022, during the Covid–2019 pandemic) I will analyze the contemporary marriage rituals: and using the results of my research I also undertake a different kind of rereading of 20th century ethnographic descriptions. My paper based on the results of my digital anthropological research carried out between 2019 and 2022 (online questionnaires, digital ethnography, and in-depth interviews).  I argue that the earlier Hungarian ethnographic approaches to weddings at the time may have been significantly influenced by prevailing Hungarian and international normative conceptualizations and theories of tradition and modernity.

Published: September 2023

This research study examines the impact of information technology on firm profitability and stock returns. Using a comprehensive dataset of firms across various industries, this research employs rigorous statistical analysis techniques to investigate the relationship between IT investments, firm profitability metrics, and stock returns. The study focuses at how IT investments affect financial performance measures including return on assets (ROA) and return on equity (ROE), with P-values of 0.34 and 0.12, respectively. Furthermore, the study investigates the influence of IT on stock returns, taking into account market capitalization, industry trends, and macroeconomic variables. This study's conclusions center on the beneficial association between IT investments and corporate profitability. The T-value for the IT investment has risen to 6.5. The analysis reveals that firms that strategically leverage IT investments tend to experience higher profitability metrics. Additionally, the research demonstrates the impact of IT on stock returns, highlighting the significance of IT as a driver of firm value and investor confidence. Moreover, this study delves into the mechanisms through which IT investments contribute to firm profitability and stock returns. It investigates the mediating role of factors such as process innovation, customer relationship management, and supply chain optimization, which facilitate the translation of IT investments into improved financial performance. The implications of this research are significant for both practitioners and policymakers. The findings provide valuable insights for firms seeking to enhance their profitability and create shareholder value through strategic IT investments. Additionally, policymakers can use these findings to formulate policies and initiatives that promote the adoption and effective utilization of IT in businesses across various sectors
Identification of regularities in the behavior of a glass fiber-reinforced polyester composite of the impact test based on ASTM D256 standard
Authors: Al-Fahad Imad O. Bachi , Hassan Azzam D. , Faisal Batool Mardan , Sharaf Hussein kadhim
Published: September 2023

In this research, commotional analysis based on the finite element analysis (FEA) has been performed to investigate IZOD impact test based on the ASTM D256 standard. The ANSYS model primarily employs a composite constructed of glass fiber-reinforced polyester for the boundary conditions. The CEAST 9050 instrument was used to implement the impacting technique in the experimental inquiry. By employing mathematics, we have calculated that the applied force is 9.2 N. A hammer traveling at a speed of 3.5 meters per second is used to strike the samples, and the results are recorded after each blow. The object of this study is the mechanical properties and structural integrity of the composite material composed of glass fibers and polyester when subjected to impact forces. The main hypothesis of the study encompasses the optimism that the glass fiber-reinforced polyester composite, when put through the Izod impact test in accordance with ASTM D256. Convergence between the overall deformation indicator and the numerical result has occurred. Results from the numerical analysis were examined and confirmed, and compared to those from the experiment. The specimens in this study were totally distorted at three different thicknesses (6 mm, 8 mm, and 10 mm). Deformation was found to be greatest for the thinnest value of thickness considered in the study (6 millimeters), as determined by the results of the computer analysis. This was the case even though the thickness value was not the sole criterion. This is the actual state of affairs. The specimen was subjected to a von-Mises stress at three different thicknesses of 6 mm, 8 mm, and 10 mm. The computer investigation revealed that the Von-Mises stress was highest at the thinnest possible thickness of just 6 millimeters. Internal energy, kinetic energy, and touch energy are only few of the various types of energy that have been studied in the context of energy conservation

Published: September 2023

O roteiro de avaliação psicológica pré-transplante intervivos representa um recurso importante para a investigação das repercussões psíquicas originários da doação, principalmente no que se refere à motivação. Esse estudo objetivou divulgar um protocolo de avaliação psicológica pré-transplante renal utilizada em um Hospital Universitário de Fortaleza-CE.  O roteiro apresenta uma proposta de avaliação multifatorial utilizado em, no mínimo, duas entrevistas, buscando priorizar, (1) o rastreio de informações introdutórias sobre o doador por meio dos dados psicossociais, funções psíquicas e suas alterações, motivação para a doação e o contexto em que surgiu essa iniciativa, (2) observação de aspectos relevantes, tais como, compreensão sobre riscos e benefícios e tomada de decisão. Constata-se, na literatura brasileira, a deficiente abordagem sobre o assunto. Acredita-se que esse instrumento pode contribuir para o desenvolvimento científico da avaliação psicológica com doador vivo no universo do transplante.

Published: September 2023

Esse estudo avaliou o nível de comer intuitivo e os fatores associados em universitários brasileiros durante a pandemia do COVID-19. Trata-se de um estudo observacional transversal realizado via formulário on-line com estudantes de graduação de uma universidade federal do sudeste brasileiro. Foi aplicado o instrumento Intuitive Eating Scale 2 (IES-2). Participaram 876 estudantes, a maioria do sexo feminino (n=647; 73,9%). Morar sozinho (OR=0,356; IC=0,176-0,719; p=0,004), apresentar sobrepeso/obesidade (OR=0,414; IC=0,261-0,656; p0,001) e comer motivado por “controle de peso” (OR=0,457; IC=0,337-0,618; p0,001) ou “controle de emoções” (OR=0,178; IC=0,129-0,245; p0,001) reduziram as chances de uma alimentação mais intuitiva. As motivações por “preferências” (OR=1,565; IC=1,037-2,364; p=0,033), “necessidade e fome” (OR=1,875; IC=1,227-2,865; p=0,004), por “saúde” (OR=1,464; IC=1,011-2,119; p=0,044) e “questões naturais” (OR=1,461; IC=1,086-1,964; p=0,012), favoreceram uma alimentação mais intuitiva. Entender essas associações pode auxiliar no rastreamento de comportamentos alimentares desordenados e estabelecimento de estratégias pautadas em uma alimentação intuitiva, principalmente no contexto de pandemia atual.

Para tanto, foi realizada uma Revisão Integrativa de literatura em trabalhos defendidos em PPGPsi que utilizaram tal método de revisão. O levantamento da literatura foi realizado em um total de 5 etapas selecionando os textos na Biblioteca Digital de Teses e Dissertações do Instituto Brasileiro de Informação em Ciência e Tecnologia, com os descritores “Psicologia” e “Revisão Integrativa”. Foi selecionada uma amostra de 51 teses e dissertações. Nos resultados, foram identificadas 6 definições distintas de Revisões Integrativas em 45% dos trabalhos. Em 55% dos trabalhos não foram identificadas definições do método.  Foram identificadas 5 variações de etapas categorizadas como referenciadas em 45% dos trabalhos e, em 47% dos trabalhos, foram descritas etapas não-referenciadas de construção. Os demais 8% dos trabalhos não apresentaram descrições do método. Foram identificados nove argumentos favoráveis ao uso das Revisões Integrativas em Psicologia, sendo o mais utilizado “Permite uma síntese do conhecimento”, que apareceu em 35% dos trabalhos. Há uma ampla apresentação de argumentos favoráveis ao uso de Revisões Integrativas, com baixa ponderação em relação às suas limitações. Conclui-se que há baixo consenso acerca da definição e das etapas necessárias à execução do método e que, portanto, há necessidade de uma proposta de diretrizes mínimas para construção de Revisões Integrativas em psicologia.

LEG carriers’ energy efficiency can be increased by improving the boil-off gas (BOG) reliquefaction installation processes in its components. In this study, it is proposed to replace the conventional reliquefaction process (CRP) of a LEG carrier “ANTIKITIRA” actual installation equipped throttle devices with an ejector reliquefaction process (ERP) having two-phase ejectors as expansion devices to increase the energy efficiency of the installation. Expansion devices EV2E and EV2R were replaced with two-phase ejectors in the proposed system. The ejector efficiencies are ensured by additional components (separators and the precooler in the bottoming stage of the cascade). Separators maintain a constant pressure at the compressor inlets, and the precooler reduces the load on the condenser-evaporator. An ejector model has been developed to analyze the proposed system. The design pressure at the ejector nozzle outlet is determined based on multivariate calculations. Energy and exergy analyses of ERP and CRP systems were carried out. According to the exergy analysis results, each component's influence on the energy efficiency of the CRP and ERP systems is estimated. The exergy losses in each ERP component are lower than the corresponding values in the CRP components. The exergy losses in the condenser and precooler of the CRP system are lower than in the ERP system. The total power consumption is the same in both cycles, and the cooling capacity of the ERP cycle has increased by 29.1 kW. Replacement of throttle devices led to a decrease in absolute exergy loss from 9.75 to 4.95 kW. The energy efficiency of the ERP cycle increased by 24%, and the exergy efficiency increased by 16%. The most significant exergy losses in both cycles are observed during compression in a two-stage cargo compressor of the bottoming stage of the cascade (29.0-34.1%). It is concluded that the proposed ERP cycle meets IMO requirements for vessel energy efficiency but requires additional capital investments

Abstract Objective To assess the level of exercise of older people with Parkinson's disease (PD), taking into account sociodemographic, clinical, and functional characteristics. Method A cross-sectional study was carried out based on the following data: level of physical activity (International Physical Activity Questionnaire short version - short IPAQ), sleep disorders, cognitive complaints, duration of illness, degree of dependence to perform basic daily activities through Schwab & England (S&E) scale of older individuals with PD treated at a tertiary health service during the covid-19 pandemic. Poisson regression, Mann-Whitney U test and Student's t test were used for statistical analysis. Results The prevalence ratio of being active increased by 1.04 (95% CI 1.01 - 1.08) for every 10 points of elevation on the S&E scale, whereas those who did not report sleep difficulties had a prevalence ratio of 1.17 (95% CI 1.02-1.34) times greater to be active. Inactive individuals with PD were older and had longer disease duration. Conclusion Emphasis should be given to the functional capacity and sleep of individuals with PD for the adequate management of the PA level in periods of social restriction.

Briefing: Engineering foresight from hindsight: why past knowledge is essential for future designers
Authors: Masterton Gordon G T
Published: September 2023

This briefing is a personal view of the value to be gained by designers of future infrastructure from researching the history of engineering projects. It exhorts current designers to consider past practice as a key field of study. Research of similar projects, and their learning legacies, should be regarded as a key preparatory stage before embarking on new designs. This is advocated as an essential component of project risk mitigation. The briefing describes the network curated by the Institution of Civil Engineers that champions 'engineering foresight from hindsight' and its three pillars – the collection of useful data; the curation of the data; education and outreach that makes use of the data. Recent activities are listed that provide examples of these principles in action, and volunteers are invited to join the community.
Open space dynamics during coronavirus disease-2019
Authors: Zhang Feiyang , Loo Becky P.Y.
Published: September 2023

Although numerous studies have been carried out to examine the general trend of urban mobility during coronavirus disease-2019 (COVID-19), there is not enough research on changes in pedestrian behavioural characteristics and crowd dynamics in public spaces. Understanding and monitoring such changes are critical for the better management and design of public open space in case of future outbreaks of infectious diseases. To fill this gap, pedestrian movements are tracked and analysed with deep learning-based video analytics based on anonymised video footage along a major promenade in Hong Kong before and during COVID-19. Specifically, comparisons were made on pedestrian-flow characteristics, pedestrian activities and social distancing. Then, this study examines the dynamics of pedestrian crowding under different scenarios, using agent-based simulation. Model results suggest that the public space was characterised by fewer visitors, a higher average walking speed, a higher percentage of people exercising and a lower percentage of people carrying out stationary activities during COVID-19. In addition, a higher level of voluntary social distancing was observed. Several hot spots for pedestrian crowding were also identified. Learning from the above, it is suggested that multifunctional public space should be designed; and data-driven visitor management systems should be established to prepare for different scenarios in future cities.

The world today is undergoing a major information revolution. This period is characterized by a serious increase in the volume of information, which, in turn, is one of the important factors in the development of technology and society as a whole. It is the development of technologies and the improvement of digital communications that have become the basis for the emergence of such a factor in world development as the digital economy. The term "digital economy" itself was first used in 1995 by an American scientist in the United States, while in Russia this term was first used only in 2017 by a Presidential Decree. Almost all countries of the world are trying to follow new trends in the development of the digital economy, but not all of them have time to adapt to changing conditions. The article discusses and analyzes the trends in the development of the digital economy in Russia and the United States of America at the present stage. This is justified by the fact that the phenomenon of digitalization and its improvement has now generated many significant changes in the economic life of people. The replacement of manual labor with artificial intelligence, the emergence of new types of information technology resources and automation are only a small part of the digitalization process. The penetration of digitalization into the economy and the lives of people in different countries occurs in different ways, in particular, it depends on the degree of involvement of the population in the process, on the level of technical equipment and proper education. The United States, one of the leaders in the number of innovation performance ratings it has led for several years, has a great influence on the digital economy. The United States is one example of the successful formation of a new type of economy, while Russia has just begun the transformation of the transition of a market economy to a digital one. A study of the specifics of the digital development of these two countries will allow a better understanding of the essence of digitalization and help to consider its trends today.

The article discusses the possibilities of developing the economic specialization of the energy profile region – the Republic of Bashkortostan. Currently, considerable attention is paid to the problems of spatial development of regions. In turn, this development is one of the most important components of the socio-economic well-being of the region. The concepts of spatial development include the adaptation of existing priorities of socio-economic development to available resources and new trends that contribute to the deformation of the existing system of division of labor. This feature includes the specialization of regional socioeconomic complexes. Historically, specialization is undergoing significant changes in the course of economic development. In order to maintain the sustainable competitiveness of the region's economy, it is necessary to constantly search for new development opportunities that provide unique advantages of the region, preferably for the long term. The purpose of the article is to search for opportunities and prospects for the development of economic specialization contributing to the preservation of the competitiveness of the region. To achieve this goal, the following tasks were solved: an analysis of the development of promising industrial specialization based on the rational use of economic resources, which includes an assessment of the current socio-economic situation and the degree of achievement of the goals of the region; an assessment of the prospects for the development of regional industrial specialization of the energy profile; justified scenarios for further development of promising industrial specialization. The optimal scenario for the economic development of the region based on the use of renewable energy sources, namely the production of biological raw materials, and biofuels from it, has been chosen. Oil-containing and sugar-containing crops are offered as raw materials for the production of biofuels. The article provides an analysis of the acreage of the Volga Federal District of the Russian Federation and the Republic of Bashkortostan, as well as the acreage of oil-bearing rapeseed culture. The practical significance of this work lies in the development of a direction that has not yet been considered by the administrative and managerial apparatus of the region, but with an appropriate level of economic justification for investments, it will ensure the socio-economic growth of the territory of the region in a strategic perspective
