Authors: Ghahremani-Moghadam Danial , Khaleghian Seyedmeysam
Published: April 2020

Background:

Friction Stir Welding (FSW) is an efficient process for solid-state joining of
two different material without melting by using a non-consumable tool. FSW process was developed
for the modification of metallic material microstructure. FSW requires a precise investigation of the
process, microstructure, and the welds mechanical properties in order to be used in the fabrication of
high- quality engineering components. Through the efforts of improving the weld's mechanical and
microstructural properties and conveying the current knowledge of the friction stir to other applications,
multiple new technologies have been developed over the time. One of the latest methods to fabricate
high performance joints or Nanocomposites alloys is the addition of nano- reinforcements to the
joint in Friction Stir Welding (FSW) or the metal matrix in Friction Stir Processing (FSP).

Objective:

In this study, an overview of effect of nanoparticles on mn this study, an overview of the effect of nanoparticles on microstructural and mechanical
properties of the FSW/ FSP joints is presented. The review revealed that the most widely employed
additions are SiC, SiO2, Al2O3, and graphite nano-powders. Microstructural evolutions, such as grain
size, second phase particles, and reinforcement distribution, usually are investigated using optical
methods and Scanning Electron Microscopy (SEM). Furthermore, the mechanical properties of the
joints, such as tensile strength, hardness, and wear performance, are also investigated. Based on most

Published: April 2020

Islamic boarding school (pesantren) is the oldest Islamic educational institution in Indonesia. Pesantren is recognized as one of the institutions that can encourage the realization of multiculturalism amongst Muslims. However, recently pesantren has been alleged to be one of the centers for the spread of religious radicalism. This study is aimed at analyzing multicultural education in salaf (traditional) pesantren, that is appropriate and be able to prevent the growth and development of religious radicalism in Indonesia. The study is a qualitative research with a phenomenological approach involving four salaf pesantrens in Java; namely Al-Qadir Pesantren of Sleman Yogyakarta, Dar al-Tauhid of Cirebon, Roudlatuth Thalibin of Rembang, and Tebuireng of Jombang. The research data were collected by observation, interviews, documentation, and focus-group discussions (FGD). Data were analyzed using an interactive technique. Findings showed that the forms of multicultural education at the four salaf pesantrens generally have similarities in the application of multiculturalism core values. However, each pesantren has its own specific peculiarities. The various cultures built up by the four caregivers of the salaf pesantrens have been effective to prevent the growth and development of religious radicalism at the  pesantren, particularly, and in the society, more generally.

Authors: Che Md Ghazali Nor Hasnida , Abdullah Norazilawati , Zaini Syaza Hazwani , Hamzah Mahizer
Published: April 2020

Teacher beliefs for conceptualisations of feedback should facilitate pupil development. However, to what extent does the conception of feedback in assessment for learning influence pupil aspirations as commanded by the Malaysian Education Development Plan? Thus, this study is conducted to explore the degree of influence of the conceptions of feedback factors on Pupil Aspiration. A survey research design is used in this study using a self-report inventory on feedback conceptions and pupil aspirations. The participants involved are 490 student teachers who have completed their teaching practical in the government schools in their previous semester. The feedback conception inventory adapted from the Teacher Conceptions of Feedback (TCoF) is used to measure the conception of feedback and the instrument for Pupil Aspiration is developed by the researchers. A structural equation modelling software, the Analysis of Moment Structures was used to test the hypothesized relationship. The analysis involves two-stage approach. Results of the study indicated that the proposed model was supported, and thus revealing that feedback conceptions was associated with Pupil Aspirations. Ten inter-correlated constructs had good psychometric properties. All the nine constructs of feedback conceptions loaded positively on pupil aspirations. The findings will give rise to further hypotheses which could close the gap of the research.

Authors: Pujaningsih Pujaningsih , Ambarwati Unik
Published: April 2020

The number of inclusive schools improves significantly in the last 10 years in Indonesia. However, there is a lack of effort to prepare future teachers so they have inadequate knowledge, skills, and experiences to provide education services for diverse students including students with special needs. This research examines the changes of Indonesian preservice teachers’ self-efficacy belief after being enrolled in a collaborative course that integrates between special education content and elementary education content. This study employed a mixed method approach for the analysis of questionnaire data from 34 preservice teachers and qualitative data of open-ended questions. The findings revealed that after being enrolled in a collaborative course, preservice teachers’ self-efficacy changed significantly (t34 = -2.16; p < .05), especially in efficacy for instructional strategies (t34 = -2.73; p < .05). The qualitative data also supported this finding based on three cases of preservice teachers who have different genders, previous experiences, and attitudes toward students with learning problems. Several recommendations for future collaborative courses and a new direction for the teacher preparation programs are discussed.

Assessment of Health Information About COVID-19 Prevention on the Internet: Infodemiological Study
Authors: Hernández-García Ignacio , Giménez-Júlvez Teresa
Published: April 2020

Background

The internet is a large source of health information and has the capacity to influence its users. However, the information found on the internet often lacks scientific rigor, as anyone may upload content. This factor is a cause of great concern to scientific societies, governments, and users.

Objective

The objective of our study was to investigate the information about the prevention of coronavirus disease 2019 (COVID-19) on the internet.

Methods

On February 29, 2020, we performed a Google search with the terms “Prevention coronavirus,” “Prevention COVID-19,” “Prevención coronavirus,” and “Prevención COVID-19”. A univariate analysis was performed to study the association between the type of authorship, country of publication, and recommendations to avoid COVID-19 according to the World Health Organization (WHO).

Results

In total, 80 weblinks were reviewed. Most of them were produced in the United States and Spain (n=58, 73%) by digital media sources and official public health organizations (n=60, 75%). The most mentioned WHO preventive measure was “wash your hands frequently” (n=65, 81%). A less frequent recommendation was to “stay home if you feel unwell” (n=26, 33%). The analysis by type of author (official public health organizations versus digital media) revealed significant differences regarding the recommendation to wear a mask when you are healthy only if caring for a person with suspected COVID-19 (odds ratio [OR] 4.39). According to the country of publication (Spain versus the United States), significant differences were detected regarding some recommendations such as “wash your hands frequently” (OR 9.82), “cover your mouth and nose with your bent elbow or tissue when you cough or sneeze” (OR 4.59), or “stay home if you feel unwell” (OR 0.31).

Conclusions

It is necessary to urge and promote the use of the websites of official public health organizations when seeking information on COVID-19 preventive measures on the internet. In this way, users will be able to obtain high-quality information more frequently, and such websites may improve their accessibility and positioning, given that search engines justify the positioning of links obtained in a search based on the frequency of access to them.
Mapping Evidence of Neonatal Resuscitation Training on the Practices of Unskilled Birth Attendants in Low-Resource Countries: Protocol for a Scoping Review (Preprint)
Authors: Olaniyi Adenike Adebola , Ncama Busisiwe Purity , Amod Hafaza
Published: April 2020

BACKGROUND

Competence in neonatal resuscitation of the newborn is very critical to ensure the safety and well-being of newborn infants. The acquisition of neonatal resuscitation skills by birth attendants improves self-efficacy, thereby reducing neonatal mortality as a result of asphyxia. Approximately one-quarter of all neonatal deaths globally are caused by birth asphyxia. The need for neonatal resuscitation is most imperative in resource-constrained settings, where access to intrapartum obstetric care is inadequate.

OBJECTIVE

This protocol describes the methodology of a scoping review on evidence of training in neonatal resuscitation and its association with practice in low-resource countries. The aim of the review is to map the available evidence of neonatal resuscitation training on the practices of unskilled birth attendants.

METHODS

The scoping review will use the Population, Concept, and Context (PCC) framework proposed by Arksey and O’Malley, refined by Levac et al, and published by Joanna Briggs Institute, while following the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews) guidelines. The search strategy was developed with the assistance of the college librarian. A number of databases of peer-reviewed research (PsycINFO and Wiley Online Library [via EBSCOhost], PubMed, MEDLINE with full text, Google Scholar [via ScienceDirect], and CINAHL Plus with full text [via EBSCOhost]) and databases committed to grey literature sources will be searched, and reference extraction will be performed. Two independent reviewers will screen and extract data, and discrepancies will be resolved by a third reviewer. The extracted data will undergo a descriptive analysis of contextual data and a quantitative analysis using appropriate statistical methods.

RESULTS

Data relating to neonatal resuscitation training and practices in low-resource settings will be extracted and included for analysis. We expect that the review will be completed 12 months from the publication of this protocol.

CONCLUSIONS

This scoping review will focus on the review of evidence and provide an insight into the existing literature to guide further research and identify implementation strategies to improve the practices of unskilled birth attendants through the acquisition of skills and self-efficacy in neonatal resuscitation. The results of this review will be presented at relevant conferences related to newborn and child health and neonatal nursing studies and published in a peer-reviewed journal.

Published: April 2020

BACKGROUND

Patients with esophageal cancer often experience clinically relevant deterioration of quality of life (QOL) after esophagectomy owing to malnutrition, lack of physical exercise, and psychological symptoms.

OBJECTIVE

This study aimed to evaluate the feasibility, safety, and efficacy of a comprehensive intervention model using a mobile health system (CIMmH) in patients with esophageal cancer after esophagectomy.

METHODS

Twenty patients with esophageal cancer undergoing the modified McKeown surgical procedure were invited to join the CIMmH program with both online and offline components for 12 weeks. The participants were assessed before surgery and again at 1 and 3 months after esophagectomy. QOL, depressive symptoms, anxiety, stress, nutrition, and physical fitness were measured.

RESULTS

Of the 20 patients, 16 (80%) completed the program. One month after esophagectomy, patients showed significant deterioration in overall QOL (P=.02), eating (P=.005), reflux (P=.04), and trouble with talking (P<.001). At the 3-month follow-up, except for pain (P=.02), difficulty with eating (P=.03), dry mouth (P=.04), and trouble with talking (P=.003), all other QOL dimensions returned to the preoperative level. There were significant reductions in weight (P<.001) and BMI (P=.02) throughout the study, and no significant changes were observed for physical fitness measured by change in the 6-minute walk distance between baseline and the 1-month follow-up (P=.22) or between baseline and the 3-month follow-up (P=.52). Depressive symptoms significantly increased 1 month after surgery (P<.001), while other psychological measures did not show relevant changes. Although there were declines in many measures 1 month after surgery, these were much improved at the 3-month follow-up, and the recovery was more profound and faster than with traditional rehabilitation programs.

CONCLUSIONS

The CIMmH was feasible and safe and demonstrated encouraging efficacy testing with a control group for enhancing recovery after surgery among patients with esophageal cancer in China.

Objective: The objectives of this study include performing pharmaceutical care-related research and documenting regarding drug-related problems in the surgery department. Further, these types of studies may bring consciousness to both physicians and patients regarding drug use in surgery.

Methods: A Prospective interventional study was conducted in a general surgery hospital. The prescriptions were analyzed for the use of inappropriateness of drugs using the classification for drug-related problems.

Results: Out of 100 cases, 62 patients were observed with drug-related problems. The number of antibiotics prescribed was 0, 1, 2, 3, 4, 5, 6 in 8, 11, 12, 32, 18, 18, 1 cases respectively. A significant increase in the outcome of antibiotic rationality and cases adhered to guidelines was seen in November compared to October and somewhat decreased in December due to some limitations. The overall study states that prescribing has a more important cause of Drug-related problems compared to dispensing and the use of the drug.

Conclusion: Drug-related problems have to be acknowledged as a very important contributing treatment factor for the best health care outcome. Our study shows the importance of clinical pharmacists in every hospital for identifying and resolving drug-related problems and medication errors.
The MODULATORY EFFECTS OF BONE MARROW-DERIVED MESENCHMAL STEM CELLS ON CYCLOPHOSPHAMIDE INDUCED HEPATOTOXICITY IN CARCINOMA MICE
Authors: ZAAZAA ASMAA MAGDY , EL-MOTLEP BOSY AZMY ABD
Published: April 2020

Objective: Cyclophosphamide (CPA) is a chemotherapeutic agent, induces hepatotoxicity as one of its side effects. Therefore, the present work was designed to investigate the protective role of bone marrow-derived mesenchymal stem cells (BM-MSCs) on CPA–induced hepatotoxicity in Ehrlich Ascites Carcinoma bearing-mice (EAC) and to test whether BM-MSCs influences the antitumor properties of the CPA.

Methods: The hepatoprotective effects of BM-MSCs (single dose of 100 µl of a cell suspension containing allogenic BM-MSCs, i. v.) was evaluated in a model of hepatotoxicity by CPA (10 mg/kg/d i. p.) in EAC-female mice for one month. The anti-tumor activities of CPA and BM-MSCs were assessed by measuring mean tumor weight, mean survival time and the increase in life span. Moreover, ALT, AST, GGT, MDA, GSH, SOD, IL-6, IL10, caspase-3 and Bcl2 were measured.

Results: The i. p. administration of CPA and BM-MSCs resulted in significant reductions in tumor size and mean tumor weight as well as caused concurrent significant increases in the life span as compared to the EAC mice. Furthermore, BM-MSCs ameliorated the liver enzyme markers namely ALT, AST, GGT, and hepatic oxidative stress through inhibition of MDA level that correlated with significant improvement in antioxidant status via increasing GSH and SOD levels as compared to both EAC and EAC+CPA groups. Moreover, BM-MSCs treatment significantly reduced the inflammatory marker level IL-6 as well as increment the level of IL-10 with subsequent decreases apoptosis via a depletion in the caspase-3 associated with an enhancement in the level of Bcl2 as compared to EAC group and EAC+CPA group. Minor histological lesions were observed in the liver tissue sections of mice treated with CPA and BM-MSCs as compared to the high histological lesions observed in the liver of the EAC group and CPA treated group.

Conclusion: These results concluded that the combination treatment of BM-MSCs with CPA exhibited promising potential antitumor efficacy with greater safety than CPA treatment alone in mice via its antioxidant, anti-inflammatory and antiapoptotic effects.

Published: April 2020

O texto em tela traz algumas reflexões resultantes de pesquisa realizada com crianças em processo de transição da Educação Infantil para os Anos Iniciais do Ensino Fundamental, cujo objetivo foi o de conhecer as significações infantis sobre este momento de passagem. Com base em algumas manifestações coletadas em roda de conversa e alicerçadas na concepção histórico-cultural do desenvolvimento humano, refletimos aqui sobre o sentido da brincadeira e do estudo como atividades principais (Leontiev, Davidov, Vigotski) que se encontram em rito de passagem e que tem sido objeto de polêmicas no âmbito do Ensino Fundamental de Nove Anos. Neste momento, nossos estudos nos permitem inferir acerca de uma criança viva, socialmente constituída que, independente da idade, vivencia a saída da Educação Infantil e entrada na Educação Escolar como um ritual importante com impactos significativos sobre si mesma e nos ajuda a identificar e concluir que os limites dessa passagem está mais nas estruturas educacionais instituídas e menos em suas significações.
A poética na docência: a apresentação do mundo pelo “artista-professor”
Authors: Cansi Lislaine Sirsi , Requião Renata Azevedo
Published: April 2020

Este artigo apresenta uma reflexão crítica sobre Educação e Arte concernente ao espaço escolar. Para tanto, os conceitos de “crise”, “natalidade” e “poiesis”, de Hannah Arendt, subsidiam a primeira parte do texto e conduzem ao pensamento do sujeito nomeado como “artista-professor”, estruturado a partir de Deleuze, Guattari, Larrosa, Vinhosa e Barthes. Em seguida, discorre-se sobre uma prática educativa compreendida como a apresentação do mundo aos estudantes pelo “artista-professor”, tendo como mote questões relevantes na contemporaneidade, no caso a categoria “território”. A prática, planejada a partir de Adriano Labbucci, intenta oportunizar experiência para estudantes do curso de licenciatura em Artes Visuais, futuros professores atuantes no espaço escolar. Tal proposta advém da crença de que a experiência vivida em seu decurso pressupõe criação e reinvenção, conduzindo os estudantes a uma “vida nova”, comprometidos com o mundo e capazes de enfrentar a crise sem preconceitos.

Published: April 2020

Teachers often encountered difficulties or even failure in conducting the classroom due to the students' inability to understand the learning materials. Most students find it's challenging to associate their existing knowledge with the new one because of the learning setting that they generally have. Teachers do not consider it important to set their students for actively engaging in learning, which eventually will impact their learning outcomes. This research aimed at determining the effect of Problem-Based Learning with Concept Mapping Technique on student learning activities. This quasi-experimental study used one experimental class and one control class. The control class used STAD model. The four categories of learning activities which were measured based on active learning principles were engagement activities, cognitive skills, response to cognitive development, and response to general educational outcomes. The result showed that  Problem-based learning with concept mapping technique is proven to have a significant effect on students' activities. There were significance difference between experiment class and control class.

Da arte figurativa à arte abstrata: uma análise psicológica
Authors: Carvalho Paulo Roberto de , Mansano Sonia Regina Vargas
Published: April 2020

Este estudo analisa o surgimento da pintura abstrata que se consolida no século XX como um acontecimento que demarca uma ruptura com o projeto comunicacional da arte. Como referencial teórico, será utilizada a interface entre Arte, Psicologia e Filosofia da Diferença que caracteriza a pintura figurativa como um tipo de representação. As referências aos seres do mundo, que dominaram a pintura por milênios, são gradativamente abandonadas e emergem registros das intensidades vividas. A pintura abstrata incide sobre a subjetividade de um modo radicalmente diferente, relacionado com a variação de potência do sujeito que vê a obra. O estudo foi dividido em dois momentos: Primeiramente, será realizada uma explanação sobre a passagem da arte figurativa à arte abstrata. Em seguida, serão consideradas as rupturas que esta passagem implicou. Como conclusão, pode-se dizer que a produção artística contemporânea já absorveu, ao menos em parte, as rupturas subjetivas provocadas pela emergência do abstrato.

Este artigo apresenta dimensões de um estudo que se ateve às experiências pedagógicas de um grupo de professores (as) de escolas públicas de Obuasi, Ghana, na África Ocidental. O objetivo é apresentar as especificidades das experiências dos (as) professores (as), por meio de uma abordagem informativa, analítica e reflexiva das relações tribais culturais no espaço escolar, da valorização identitária dos povos de Ghana, da importância da educação bilíngue, do desafio de ser professora ou professor em uma escola com pessoas falantes de diversos idiomas, com conhecimentos prévios distintos e expectativas em relação à educação escolarizada. A metodologia envolveu etnografia virtual. Dada a singularidade da pesquisa realizada, utilizou-se tecnologias digitais, ambiente virtual, e aplicativo de mensagens. A primeira parte do estudo ocorreu quando professores (as) de Obuasi foram á cidade de Sabará, em Minas Gerais, Brasil, para uma troca de experiência na cidade que reconheceram ser uma cidade irmã. Neste artigo tratamos da segunda parte da troca de experiências, quando os professores de Ghana, após retornarem ao seu país, iniciaram um diálogo com as autoras do presente artigo. Que este estudo possa fortalecer os projetos, reflexões e intervenções promovidas pela Educação das Relações Raciais e as africanidades brasileiras. Este estudo caracterizou-se por ser uma construção a partir da vivencia compartilhada, que se assemelhou ao processo de tecer uma das tiras do tecido Kente, de Ghana. Nesse entrelaçar é preciso continuar a tecer até completar o tecido do conhecimento, que segue sempre demandando mais tecituras.

A pesquisa da informação e o desenvolvimento do progresso de alta tecnologia no aspecto sócio-humanitário nos permitiu revelar suas consequências no contexto de desafios naturais e civilizacionais e áreas de financiamento da educação. A gestão de riscos e as tendências gerais foram esclarecidas quanto ao desenvolvimento inovador da educação nas instituições na era do progresso da informação em alta tecnologia e mudanças civilizacionais naturais, que criaram fundamentalmente novas oportunidades para justificar estratégias educacionais e devem basear-se nas categorias de pedagogia da direção noosfera-espaço. Portanto, é necessário construir novas teorias pedagógicas sobre a síntese das abordagens filosófico-educacionais, filosóficas-antropológicas, poliparadigmais, civilizacionais-formacionais e culturais. De acordo com esse princípio, a aprendizagem ao longo da vida se torna importante para enfrentar os desafios do progresso moderno e combater as mudanças naturais e civilizacionais destrutivas.
Građevni redovi i regulatorno planiranje Zagreba od 1900. do 1918. godine
Authors: Jurić Zlatko
Published: April 2020

Nakon neuspjeloga pokušaja zagrebačkoga gradskog načelnika Adolfa Mošinskog i vijećnika Adolfa Hudovskog da se donese građevni red 1894., godine 1908. i 1909. traje rasprava o tri varijante (smjera) realizacije
novoga prijedloga građevnoga reda grada Zagreba, koje su razrađene i analizirane u ovome članku.
Prva je varijanta Vladoja Eisenbarta, koji je nastavio i razradio ideju građevnoga reda kao jednoga od osnovnih instrumenata u reguliranju
gradova. Eisenbartov tekst iz 1908. preradio je kolektiv autora brojnim
primjedbama nakon dugotrajne rasprave u konačni prijedlog iz 1909. godine. Drugu varijantu zagovarali su inženjeri Antun Kostial st., Mirko
pl. Ferrich, Kamilo Bedeković i odbor Hrvatskoga društva inžinira i arhitekta, koji su Eisenbartov prijedlog iz 1908. promatrali na dvije razine. Oni su odbacili ideju i svrhu građevnoga reda kao isključivo regulatornoga dokumenta i pretvorili ga u razvojni gospodarski dokument.
Odbor se neočekivano preobrazio u žestokoga zagovornika privatnoga vlasništva i poduzetništva. Treću varijantu zastupao je gradski načelnik
dr. Milan Amruš, koji je forsirao osnivanje građevnoga odbora i bitno smanjivanje ovlasti i važnosti Gradskoga poglavarstva i zastupstva. Glavni problem u prijedlogu bilo je uvođenje građevnoga odbora kao posebne građevne oblasti koja bi s predloženim ovlastima suspendirala građevnu oblast prve molbe (Gradsko poglavarstvo) i kontrolno djelovanje
Gradskoga zastupstva. Bez obzira na postojeće stranačke podjele i osobne animozitete zastupnika, prijedlog osnove građevnoga reda iz 1909.
nije imao nikakve izglede prilikom glasanja u Gradskom zastupstvu.

Field experiments were conducted at the Teaching and Research Farm of the
Federal University of Agriculture, Abeokuta (7o 20?N, 30 23?E) during the
2014 early and late cropping seasons to evaluate the effect of weeding
frequency and phosphorus fertilizer application on the growth and grain
yield of the early maturing cowpea variety (Vigna unguiculata L. Walp). The
experiment was laid out in a split-plot arrangement fitted into a Randomized
Complete Block Design with three replications. The main plot consisted of
three phosphorus fertilizer rates (0, 15 and 30 P2O5kg ha-1) while the
subplot comprised five weeding frequencies (no weeding, weed-free, hoe
weeding at 3 weeks after sowing (WAS), hoe weeding at 3 and 6 WAS and
weeding at 3, 6 and 9 WAS). The results showed that plots treated with
phosphorus fertilizer at 15 kg ha-1 produced the highest number of leaves
and the tallest plant in the late season while the highest grain yield was
recorded in the early trials. Weeding at 3, 6 and 9 WAS during the early
season trial gave the highest grain yield compared with other weeding
treatments. Unchecked weed infestation reduced yield by 53.10 % and 49.9 %
in the early and late seasons respectively compared to the maximum obtained
from weed-free plots. This study concluded that application of 15 kg P2O5
ha-1 and weed removal at 3, 6 and 9 WAS were effective for effective weed
control and optimum grain yield in cowpea production.
Contribution of a cognitive interview to assessing the validity of indicators and data quality in quantitative research on the example of attitudes toward gays and lesbians
Authors: Filipovic Bozidar
Published: April 2020

Empirical research on different problems and aspects of the LGBT population
is no longer so rare in Serbia. This community and its problems are often
the cause of strong reactions in one part of society. Therefore, attitudes
of the general population towards the LGBT community can be used for
creating value orientations indicators. In this paper, we will show the
importance of cognitive interviews in the assessment of such indicators. A
cognitive interview allows us to methodologically investigate the validity
of the questions (statements) used in the questionnaire. The indicator to
which we have paid attention in this paper (?Gay men and lesbians should be
free to live their life?) is a good example of what role a cognitive
interview can have in sociological research. By using the cognitive
interview, it is possible to explore the different meanings that respondents
attach to specific statements or specific terms. As such, the method also
points to ?unexpected? meanings that the researchers did not have in mind.
Modeling reacting multi-species flows with a detailed multi-fluid lattice Boltzmann scheme

Published: April 2020

Recent advances and findings reported in the literature show that the lattice Boltzmann method can be a viable and rather efficient alternative to classical numerical methods in modeling multi-species flows. Based on the kinetic theory of multicomponent gases, multi-fluid approaches are derived. Each species evolves according to the specific properties, a proper coupling must be introduced for modeling the diffusivity. In recent years, a discrete kinetic scheme for multi-component flows has been proposed which was able to solve the Maxwell-Stefan system of equations for any number of species. However, reacting flows lead to additional challenges and have seldom been studied by lattice Boltzmann method. The aim of the present work is to implement this model in the lattice Boltzmann solver, extend it to take account multiple chemical reactions. The temperature is modeled through separate distribution function and the flow distribution function is assumed to be independent of temperature. The performance has been checked for a binary diffusion flow and a counter-current propane/air re-acting flow. The obtained results show that this model able to deal with multi-species flows and solves the multi-component system of equations.
Experimental study on the effect of the liquid/surface thermal properties on droplet impact
Authors: Lamini Omar , Wu Rui , Zhao Changying
Published: April 2020

Droplet impact on hot surfaces is widely encountered in industry and engineering applications. In the present paper we investigate the effect of the combination of the droplet liquid type and the solid surface type and their effect on droplet impact dynamics. We test three surfaces, copper 110, aluminum 1199, and stainless steel 304, and two liquids, water and ethanol. These surfaces and liquids are characterized by high and low thermophysical properties. The three surfaces are tested with water to investigate the effect of the surface on the droplet dynamics. After that, we test both liquids with aluminum. Our findings showed that the Leidenfrost temperature does not always correlate with the surface thermal proper-ties as reported in the literature. Some surfaces can undergo changes because of the heating and this reduces their initial thermal properties. For this reason, such surfaces are capable to show two Leidenfrost temperatures because of the thermophysical properties reduction during heating. Our findings also revealed that the Leidenfrost temperature of liquids with low thermophysical properties including surface tension, evaporation latent heat and density show trivial effect by the droplet impact velocity; i.e. the Leidenfrost temperature show trivial increase by increasing the droplet impact velocity. Liquids with high thermophysical proper-ties show significant Leidenfrost temperature increase by increasing the impacting velocity.

Published: April 2020

In this study, polyamide 6 polymer surfaces that have a high surface area were produced by electrospinning method with the participation of Glycine, Tyrosine and Glutamic acid amino acids, and lyophilized Bacillus subtilis E6-5 protease and commercial protease enzymes were immobilized on nanofibrils. Enzyme reusability were investigated. The immobilization efficiencies of the enzymes were approximately between 50-55 %. In studies with lyophilized Bacillus protease, glutaraldehyde activated PA6 nanofibrils and glutaraldehyde unactivated PA6 nanofibrils were found to be more immobilized in the presence of Glutamic acid. Although the lyophilized protease enzyme immobilized on non-glutaraldehyde activated and activated surfaces has been used 4 times, the best functional stability has been achieved with 2 times use. In pure PA6/Glutamic acid nanofibrils, the immobilization yield of the two times used enzymes was found to be 38 %. In glutaraldehyde-activated PA6 nanofibrils, the PA6/Glutamic acid nanofibril surfaces were found to have 65 % immobilization yield of the two repetitive used enzymes. The enzyme immobilization efficiency has been doubled by glutaraldehyde activation of the nanofibrils. In studies with commercial protease, the most functional stability was obtained for 3 repeated uses, although the enzyme was used 6 times on the non-glutaraldehyde activated nanofibril surfaces. The most successful immobilization was found in 58 % of PA6 nanofibrils. In glutaraldehyde-activated PA6 nanofibrils, the enzyme was found to be used 6 times, but the functional stability was maintained as much as 4 times of repeated use.
