Authors: Quyen Ngo Thi Cam , Van Tan Lam , Bach Long Giang , Hoang Bich Ngoc
Published: July 2023

Vietnam is one of the agricultural coconut exporting countries in the world. Therefore, by-products from coconut were discharged into the environment a lot. Using coconut as activated carbon is one of the ways to increase the value of coconut products. In addition, activated carbon from coconut can handle pollutants from the environment. In this study, activated carbon from coconut was synthesized by microwave-assisted method to treat the antibiotic Ciprofloxacin. The physicochemical properties of activated carbon were analyzed using FTIR, XRD, and BET methods. The semi-morphic structure and functional groups have shown structural characteristics. The factors affecting the adsorption process, such as pH, concentration, and dosage, were also evaluated. Fixed parameters include time 20 min and temperature 30 °C. The adsorption process was also evaluated with kinetic and isothermal models of adsorption. The kinetic and isothermal models suitable for the material were Pseudo-first-order and Langmuir. The influencing parameters would be optimized by the RSM model. Optimal parameters are pH 3.97, concentration 85.67 mg.L-1, content 0.51 g.L-1. From the optimal parameters, the adsorption capacity and treatment efficiency were also predicted to be 73.75 mg.g-1 and 42.6%. This helps the process of treatment and adsorption of pollutants to achieve the highest efficiency.

Published: July 2023

Background: hospital infections affect about 6% of hospitalised patients in Europe; the hands of healthcare workers, who are front-line staff and frequently exposed to infected patients and contaminated surfaces, are the primary source of microbial transmission. Thus, hand washing procedures are essential to lowering the risk of occupational exposure to infectious diseases, hospital-acquired infections, and micro-organism cross-transmission. The aim of this study was to see if the COVID-19 pandemic had any effect on hand-washing adherence rates by conducting a pre-post pandemic wave study from the pre-pandemic year 2019 to the post-pandemic years 2020/2022. Methods: an observational, retrospective, single-center study. The study considers hand hygiene observations of all personnel employed as healthcare staff from 2019, during the pre-pandemic period, and in the three years following the outbreak from 2020 to 2022, during the post-pandemic period and a specific study on hydroalcoholic gel consumption. The study will use the “Hand Hygiene Observation Form”, to evaluate adherence to best practices. Conclusions: a dedicated facility that promotes the application of the recommended hand hygiene behavior and ongoing improvement and training initiatives, is crucial to ensure and improve the compliance of all healthcare workers.

Authors: Rajeswaran Priyadarshini Kumaraswamy , Kumar Prasanna Nedungadi , Shanmugam Karthikeyan
Published: July 2023

Background:

Dengue fever is a common tropical illness caused by an arbovirus. A complete blood count is one of the standard investigations performed on a febrile patient. The automated hematology analyzer utilizes the principle of volume (V), conductivity (C), and scatter (S) to generate total and differential leukocyte counts. The present study analyzed the utility of volume, conductivity, and scatter (VCS) parameters in the early diagnosis of dengue.

Subjects and Methods:

In this study, 700 blood samples were analyzed in the Beckman Coulter LH 780 analyzer. Their total, differential leukocyte counts, lymphocyte, and monocyte VCS parameters were collected. Demographic and clinical details of the patients were retrieved, and statistical analysis was done using IBM SPSS statistics, version 23.0.

Results:

Among the 700 cases, 271 (38.7%) had viral illnesses and 429 (61.3%) were patients who had diagnoses of nonviral causes. Of 271 viral illnesses, 168 (62%) cases had dengue. There were statistically significant differences (P < 0.05) in total and differential leukocyte counts and VCS parameters of lymphocytes and monocytes in dengue and nondengue viral causes when compared with nonviral causes. For the diagnosis of dengue, mean lymphocyte volume at a cutoff value of above 77 achieved a sensitivity of 60% and specificity of 61% and mean monocyte volume above 145 had a sensitivity and specificity of 62% and 59%, respectively.

Conclusion:

This study showed changes in VCS parameters of lymphocytes and monocytes, which can be utilized for the early diagnosis of dengue. They can be used, without incurring additional costs, to generate flags to prompt specific testing independent of clinical suspicion.

Published: July 2023

A mass of hair found trapped in the gastrointestinal system is termed a trichobezoar. Complications such as gastric ulceration, bleeding, perforation, and intestinal obstruction may occur. There is a relative paucity of reports on trichobezoars in psychiatry compared to the surgical literature. Here, we present a case of trichotillomania and pica leading to intestinal obstruction. Our aim was to emphasize the importance of considering trichobezoars as one of the differentials in cases of patients presenting with unexplained abdominal pain, even if clear signs of trichotillomania are not present.

Published: July 2023

The objective of this research was to determine the effect of adding a mixture of different exogenous enzymes at 0.005% (0.0025% for each enzyme; protease+xylanase [P/X], protease+cellulase [P/C], and xylanase+cellulase [X/C]) to diets, based on fishmeal (FM) or soybean paste (SP), on shrimp`s growth performance, survival, feed conversion, digestibility, and digestive capacity. Eight isoproteic experimental diets (FM, FM+P/X, FM+P/C, FM+X/C, SP, SP+P/X, SP+P/C, and SP+X/C) were evaluated with three replicates. Shrimps (1  0.2 g) were maintained in a recirculating system at 12 organisms/tank for 90 days. Significant differences (p ˂ 0.05) were found in all the productive parameters of L. vannamei. Compared with the control diets (FM and SP), shrimps fed with FM+P/C showed the highest final body weight (7.83 ± 0.34 g) and proteolytic activity (178.81 ± 24.49 U/mg protein), as well as the lowest feed conversion ratio (1.71 ± 0.01). In contrast, the SP+X/C group presented the highest lipolytic activity (0.0235 ± 0.0028 U/mg) and apparent digestibility (94.12 ± 0.09%). In accord with its omnivorous trophic habits, enzyme mixtures included in animal and plant based-diets improved different productive variables of L. vannamei, representing a nutritional alternative to optimize feed use in shrimp cultivation.
Influence of Epigallocatechin Gallate on Quality of Cooked Harpiosquillid Mantis Shrimp (Harpiosquilla raphidea) Subjected to Multiple Freeze-Thaw Cycles

Published: July 2023

Effects of epigallocatechin gallate (EGCG) at 200 or 400 ppm on quality changes of cooked Harpiosquillid mantis shrimp (Harpiosquilla raphidea) (CHMS) meat subjected to varying freeze-thaw cycles (F-T-C; 0, 1, 3, and 5) were studied. With augmenting F-T-C, the CHMS meat underwent deterioration to higher extent as indicated by upsurges in exudate loss, tougher texture along with increased microbial counts. The addition of EGCG could retard those changes in a dose-dependent manner. Furthermore, EGCG prevented microbial growth as ascertained by lower counts and total volatile basic nitrogen (TVB) content. Lipid oxidation was also impeded in the presence of EGCG, especially at a high concentration as evidenced by lowered malondialdehyde (MDA), while maintaining polyunsaturated fatty acids, particularly EPA and DHA when F-T-C raised. Total disulfide bond content and surface hydrophobicity of CHMS added with EGCG were lower than those of the control. Those alterations were more retarded as EGCG concentration increased. Therefore EGCG at 400 ppm effectively prevented quality loss of CHMS meat during repeated F-T process.

The first aim of the present study was to determine appropriate artemia enrichment levels by using Aurantiochytrium mangrovei FIKU008 served as DHA enrichment source and secondly to test the effects of enriched-Artemia on growth and survival during the early larval stages(M1-PL7) of Penaeus semisulcatus. In the 1st experiment, four different enrichment levels of AUR (0.0,0.6,0.8 and 1.0g/L) against a control commercial solution (S-presso) were tested for 12/24-hours enrichment while in the 2nd experiment, three levels (0.0, 0.6 and 0.8g/L) of AUR enriched-Artemia were fed to larval stages. At the end of both enrichments, DHA and EPA levels were found to be significantly enhanced by using AUR at 0.6 and 0.8g/L. In the 2nd experiment, fatty acid composition of the PL was significantly affected by AUR and the PL fed with enriched diets showed higher n-3 LC-PUFA accumulation in their tissues. The larvae grown from M1 to PL7 displayed higher survivals and growth in the enriched AUR-groups compared to the control(0.0AUR). In conclusion, this study has demonstrated that the use of AUR as enrichment significantly elevated EPA and DHA levels to 0.6-0.8g/L enrichment periods and the enriched-Artemia at such levels were proven to effectively improve growth and survival of the early larval stages of P. semisulcatus.

Published: July 2023

Visceral leishmaniosis is one recent example of a global illness that demands our best efforts at understanding. Thus, mathematical modeling may be utilized to learn more about and make better epidemic forecasts. By taking into account the Caputo and Caputo-Fabrizio derivatives, a frictional model of visceral leishmaniosis was mathematically examined based on real data from Gedaref State, Sudan. The stability analysis for Caputo and Caputo-Fabrizio derivatives is analyzed. The suggested ordinary and fractional differential mathematical models are then simulated numerically. Using the Adams-Bashforth method, numerical simulations are conducted. The results demonstrate that the Caputo-Fabrizio derivative yields more precise solutions for fractional differential equations.

Choosing Thermos chemical Storage Materials for High Temperatures Using a MCDM Methodology
Authors: Muthusamy P , Arivudainambi J
Published: July 2023

Because of its inherent variability, intermittency, and technological and economic difficulties, currently, manufacturing waste heat is underutilized. One of the best methods for removing obstacles, lowering greenhouse gas emissions, and safeguarding the ecosystem at large is energy recovery. The process of choosing materials is crucial to the design of heat storage devices. Complex interactions between a number of variables and parameters are necessary to produce the finest candidate material for a particular appli-cation. The selection of high-temperature thermo chemical storage (TCS) materials is addressed in this re-search using a matrix-based multi-criteria decision-making (MCDM) approach. The Port Talbot Steelworks also utilized the suggested method to select suitable components for high temperature waste heat recovery (above 500 C). In this article, a COPRAS set theory-based multi-criteria decision-making (MCDM) model is proposed. Alternatives include MgH2, MgH2/Composite, Mg2FeH6, Mg2NiH4, MgO/Mg(OH)2, and Heat Release Temperature. Evaluation criteria also include Reaction Enthalpy, Volumetric Energy Densi-ty, Mass Energy Density, and Heat Charge Temperature. Because of this, remanufacturing is ranked first and refurbishing is ranked last. Compared to other options, Mg2FeH6 is superior.
A arte da educação e a educação pela arte

Published: July 2023

Neste artigo, os autores ensaiam uma reconceptualização da atividade pedagógica, estabelecendo distância crítica face à visão tecnicista e performativa que está implícita em muitos dos processos de avaliação da sua qualidade. Neste sentido, denunciam o vácuo ontológico que invalida a perspetiva construtivista da ação educativa e buscam um nexo da educação com o domínio artístico para compreender as potencialidades criativas da arte e o seu impacto na formação dos indivíduos, excluindo o fundamentalismo da mensuração que nutre a miséria simbólica e abre caminho para a robotização do humano.
Os valores pessoais e a inteligência emocional como antecedentes do comprometimento no local de trabalho - a relação de influência sobre os comportamentos desviantes
Authors: Santana-Martins Marisa , Nascimento José , Sanchez-Hernadez Mª Isabel
Published: July 2023

O comprometimento tem sido considerado quer por autores quer pelas organizações como um tema que se reveste de especial cariz estratégico, ao constituir um meio de retenção do talento, mas também uma condição que potencia o nível de desempenho dos trabalhadores. A competitividade e a necessidade de comprometer o talento têm colocado à gestão de recursos humanos grandes desafios, na necessidade de adotar medidas estratégicas sobre um fenómeno relativamente abstrato, que tem inerente a possibilidade de coexistência de múltiplos objetos de comprometimento no contexto laboral. De acordo com a necessidade de estudos empíricos que auxiliem a tomada de medidas, este artigo sugere um modelo de estudo integrado que inclua a análise de antecedentes e consequentes do comprometimento, conjuntamente com uma análise multinível que permita analisar a transferência de níveis de comprometimento entre diferentes hierarquias da estrutura organizacional. O presente trabalho constitui um artigo conceptual que fundamenta a necessidade da conjugação de diferentes linhas de investigação e metodologias, procurando um conjunto de insights que auxiliem a tomada de decisão nas organizações face a medidas de comprometimento. Propõe-se assim, identificar em que medida os valores pessoais e a inteligência emocional dos trabalhadores podem ser antecedentes do comprometimento organizacional e com o superior hierárquico, bem como qual a sua relação nos comportamentos desviantes.

Authors: André José , Pinto José
Published: July 2023

Neste trabalho é aplicado um modelo, desenvolvido previamente pelos autores, que permite prever a relaxação de tensões de polímeros amorfos e semi-cristalinos, que contempla a interligação da temperatura e a deformação. As alterações induzidas pela deformação foram investigadas através de ensaios de relaxação não linear de tensões em dois polímeros a três temperaturas. O modelo é sensível a diferentes estados iniciais do material, resultantes da variação da orientação molecular, bem como de distintos níveis de envelhecimento, e a partir de dados experimentais do módulo de relaxação de tensões prevê para o poli(metacrilato de metilo) – PMMA e o poli(tereftalato de etileno) – PET os valores da temperatura crossover, Tc, da energia de ativação mínima, Eα,1, para além do patamar dos módulo de relaxação instantáneo, E0, e o patamar do módulo para tempos longos, E∞, de acordo com os valores encontrados na literatura.

Published: July 2023

A nível internacional, a adoção da metodologia BIM (Building Information Modeling) está em rápida expansão, sendo já uma realidade em diversos países. O nível de implementação e maturidade difere entre os diferentes países. Vários governos estão a estimular a mudança de paradigma no setor de construção, procurando que esta alteração possa promover uma maior eficiência e produtividade. No entanto, para que esta mudança ocorra, é necessário saber o seu nível de implementação para se definirem as melhores estratégias de incentivo. Em comparação com outros países, Portugal parece estar num estado inicial de adoção do BIM. Este atraso é mais pronunciado nas regiões Centro e Alentejo, que são o objeto deste estudo. Os resultados podem servir para melhorar as estratégias de adoção da metodologia BIM no setor das AEC destas regiões. Nesta pesquisa, constatou-se que 73% dos entrevistados possuem algum conhecimento em BIM. Este resultado é superior ao obtido num estudo efetuado em Portugal no ano 2015, e pode ser consequência das inúmeras iniciativas realizadas para difundir a metodologia BIM que ocorreram entre os anos 2015 e 2018. Noutros parâmetros não existem diferenças significativas entre os resultados das duas pesquisas.

Authors: Ribeiro Maria , Antão Celeste , Fernandes António
Published: July 2023

Embora tenha havido grande progresso no controlo da brucelose, ainda existem regiões onde a infeção persiste em animais domésticos e, consequentemente, a transmissão para a população humana ocorre com frequência, provocando brucelose aguda e crónica. Neste contexto, este estudo teve como objetivos caraterizar e detetar alterações das tendências temporais relativas à brucelose em Portugal e na União Europeia (UE) e comparar as médias registadas por cada 100 mil residentes. Trata-se de um estudo retrospetivo, desenvolvido com base em dados secundários sobre o número de casos de brucelose em Portugal e na UE notificados e registados, entre 2007 e 2017, e dados da população residente. Os dados foram analisados através do software Joinpoint, versão 4.6.0.0, para estimar a regressão para cada tendência. Para comparar as médias dos casos notificados em Portugal e na UE, foi utilizado o software IBM SPSS versão 25.0 e aplicado o teste t-Student para amostras emparelhadas. Os resultados mostram que, em ambas as regiões estudadas, registou-se uma diminuição nos casos notificados de brucelose. As variações percentuais anuais no período analisado, para Portugal e para a UE, foram de -9,4% e -4,6%, respetivamente, para um intervalo de confiança de 95%. Verificaram-se diferenças estatisticamente significativas entre as médias registadas, por cada 100 mil residentes, de casos notificados de brucelose em Portugal e na UE (pvalue < 0,05). Portugal regista mais do quádruplo de casos notificados comparativamente à UE no período analisado. Estes resultados revelaram a existência de uma tendência de diminuição de casos de brucelose quer em Portugal quer na UE, sendo a diminuição mais acentuada em Portugal.

Published: July 2023

As lesões músculo-esqueléticas (LME) relacionadas com o trabalho dos músicos profissionais constituem atualmente um verdadeiro problema de saúde publica. Assim, objetivamos identificar a prevalência e os determinantes das lesões músculo-esqueléticas em músicos profissionais praticantes de cordofones beliscados (CB). Trata-se de um estudo transversal, descritivocorrelacional e de caráter quantitativo, que envolveu 140 músicos portugueses com idades compreendidas entre os 18 e os 55 anos. Foi utilizado um questionário que integrava variáveis sociodemográficas, de saúde e da prática musical. Para avaliação das LME utilizámos o “Questionário Nórdico Músculo-Esquelético”.Os resultados mostraram que 70,0% dos inquiridos referem LME, aos níveis dos punhos/mãos (68,6%), ombros (54,3%), pescoço e região lombar (44,3%). As LME são mais frequentes em músicos mais velhos, com Índices de Massa Corporal mais elevados, e nos que realizam maior número de espetáculos. Concluímos que a prevalência das LME nos músicos de cordofones beliscados é elevada e estão associadas a características individuais, estilos de vida e exigências da prática instrumental.

No entanto, as redes sociais digitais continuam a ser muito populares por permitirem promover espaços de diálogo onde se fomentam as relações interpessoais e se reduz o isolamento, o qual é muito frequente entre os adultos mais idosos. A literatura tem evidenciado as potencialidades das tecnologias digitais na promoção de melhorias no processo de envelhecimento, uma vez que, o processo de envelhecimento está associado a um processo de degenerêscia biológica, cogntiva e motora que impede o normal desempenho das rotinas diárias dos adultos idosos. O objetivo deste artigo é avaliar o impacto das tecnologias digitais em adultos e idosos que frequentam a Universidade Sénior. As investigações foram de caráter qualitativo no âmbito de um estudo exploratório. Uma das investigações realizadas utilizou o Facebook com o objetivo de averiguar o impacto ao nível do isolamento e relações interpessoais. Outra investigação fez uso das Apps Neuronation e Peak, tendo em vista a promoção de estímulos e treino cognitivo. Os resultados indiciam que os idosos que utilizam o Facebook podem ter um melhor envelhecimento ativo, pelo incremento nas relações interpessoais e redução do isolamento. Também ficou demonstrado que o uso de Apps pode constituir uma boa opção para a estimulação e o treino cognitivo, contribuindo para a prevenção de potenciais demências.
