Heterogeneous Elliptic BVPs with a Bifurcation-Continuation Parameter in the Nonlinear Mixed Boundary Conditions
Authors: Cano-Casanova Santiago 
Published: July 2019

Abstract
This article ascertains the global structure of the diagram of positive solutions of a very general class of elliptic boundary value problems with spatial heterogeneities and nonlinear mixed boundary conditions, considering as bifurcation-continuation parameter a certain parameter γ that appears in the boundary conditions. In particular, in this work are obtained, in terms of such a parameter γ, the exact decay rate to zero and blow-up rate to infinity of the continuum of positive solutions of the problem, at the bifurcations from the trivial branch and from infinity. The new findings of this work complement, in some sense, those previously obtained for Robin linear boundary conditions by J. García-Melián, J. D. Rossi and J. C. Sabina de Lis in 2007. The main technical tools used to develop the mathematical analysis carried out in this paper are local and global bifurcation, continuation, comparison and monotonicity techniques and blow-up arguments.

Published: July 2019

Abstract
The time and velocity of ejection of dust particles of anomalous tails from cometary nuclei are determined. It is revealed that some comets cause the formation of an anomalous tail is the collision of their comet nucleus with other bodies of the Solar System. An investigation of the formation conditions of the anomalous tail shows that the dust ejection velocity from the comet nucleus C/1851 U1, C/1885 X2, C/1921 E1, C/1925 V1, C/1930 D1, C/1975 V2, 2P/1924, 6P/1950 and 1976, 10P/1930, 7P/1933 and 35P/1939 O1 can be explained by the sublimation of the ice of the nucleus and the removal of dust by molecules. It was found that the comets C/1823 Y1, C/1882 R1, C/1883 D1, C/1888 R1, C/1892 E1, D/1894 F1, C/1932 M1, C/1954 O1, C/1968 H1, C/1969 T1, C/1973 E1, C/1995 O1, C/1999 S4, C/2004 Q2, 7P/1869 G1, 10P/1930, 19P/1918, 26P/1927 F1, 67P/1982, 73P/1930 J1, 96P/1986 J1 and 109P/1862 O1, formation of the anomalous tail and splitting of the comet nucleus was observed in one appearance. Nuclear splitting 70% of these comets occurred as a result of a collision of the comet’s nucleus with a meteoroid or fragments of their nuclei.
“It comes from you”: Agency in adult asylum seekers’ language learning through Process Drama
Authors: Dalziel Fiona , Piazzoli Erika 
Published: July 2019

Abstract
In this paper, we present a study of adult asylum seekers learning Italian as a Second Language through Process Drama. Adopting an ecology of language approach, we first set the scene by examining some of the most salient issues regarding the language learning needs of asylum seekers and refugees, including the challenge of fostering both language proficiency and a sense of autonomy and agency. We then introduce the topic of performative, or drama-based pedagogy, focussing on how this has been adopted for second-language learning, presenting the main features of Process Drama. We go on to evaluate a number of drama-based projects aimed specifically at adult asylum seekers and refugees before presenting the specific context of this study. The Process Drama sessions, organised in the 2016/2107 year, were part of a project called “Cultura e Accoglienza”, which allowed for the enrolment of 30 asylum seekers as “guest students” at the University of Padova in Northern Italy. In particular, we look at one of the Process Drama sessions, in which the participants became members of an association of community workers welcoming migrants, and the teacher took on the role of the asylum seeker. Through the dramatic frame, we, as facilitators, drew on the learners’ expertise in settling into the Italian culture, and in welcoming new arrivals. Our aim was that of using ‘time’, ‘place’ and ‘role reversal’ as distancing devices to challenge the notion of ‘otherness’. The analysis from videos, focus groups and teacher journals suggests that the drama gave participants the chance to shift perspective, and that this impacted on their sense of agency as second language learners.
Language teachers’ perceptions of multilingualism and language teaching: The case of the postgraduate programme “LRM”

Published: July 2019

Abstract
This paper explores the language views and practices of postgraduate student-teachers attending a distance-learning Master’s Programme of a Greek University, entitled “Language Education for Refugees and Migrants” (LRM). Teachers and professionals working with language learners in linguistically diverse contexts make up an interesting research sample in order to explore their perceptions and practices concerning bi/multilingualism and language learning. The study was conducted through an open-ended questionnaire, delivered and completed electronically by the student-teachers of two modules of the Programme (LRM 53: Language teaching for adult refugees and migrants and LRM54: Language teaching for children with refugee and migrant background) and included open-ended questions regarding their profile, their perceptions towards bi/multilingualism and translanguaging, language use in the school context, the first language and its relation to second language learning. Taking into account the students’ sample profile, the data can provide insights into the ways student-teachers view and deal with language diversity in their classrooms. Issues of attitudes and practices towards multilingualism and language teaching are discussed in relation to students-teachers’ professional development/education. Also, through comparisons between the two groups of students of the modules, the results are expected to explore some common ground assumptions on the differences between language teaching for children and adults (in the refugee context) but also potential nuances and elements of distinctiveness in the two areas.
Wor(l)d order and coloniality in language education for migrants. Key ideas for thinking otherwise
Authors: Dell’Olio Francesca 
Published: July 2019

Abstract
Migration has become an important phenomenon in the contemporary world. In receiving countries, language policies have been put into place to offer migrants education in the national language, in order to give them tools to communicate with and to create a feeling of belonging to the local community. These policies claim to be integration policies; however, they are frequently based on a concept of languages disconnected from the notions of knowledge, culture, politics and power. Languages are shaped in a specific global order and in local practices, in which power relationships that respond to a political, social and economic world system are enmeshed. This paper uses “key-ideas” constructed from data generated in classroom observations and open-ended interviews in Padova, Italy and São Paulo, Brazil as theory promoting insights, and also reflects on the concepts of language, nation and integration. I will engage in a dialogue with the readers, stimulating reflection on encounters with the “other” and on the implications of actions when situated in contexts that are based on a homogenous concept of language, nation and culture. Moreover, through the theorization of coloniality, this article aims to offer a diversified reading of these encounters, suggesting that a process of subordination of the other is put into place by hierarchizing languages and their epistemic meanings. Together with theory, some questions will be offered to stimulate readers in the process of developing their own pedagogical activities.
Mobile language learning applications for Arabic speaking migrants – a usability perspective
Authors: Al-Sabbagh Khaled Walid , Bradley Linda , Bartram Lorna 
Published: July 2019

Abstract
Usability testing with mobile applications (apps) plays an important role in determining the ease of use of an app as well as in informing their design and development. The purpose of this research is to investigate the usability of three language learning apps with a sample of Arabic speaking migrants who have recently arrived to Sweden. In addition, We surveyed available apps for the target group on both Android and Apple market stores and used a framework for categorizing language learning apps to guide the design and development of our own app. The outcomes show that in order for users to engage in an app, there are a number of obstacles that need to be overcome to make an app motivating enough to use, such as lack of variation in functionality, instructions and feedback. Our app, Minclusion, was developed from the input obtained from the usability studies.
Preparing adolescent refugees for study and work in the Netherlands: Start-up of an academic pre-Bachelor’s programme
Authors: Roselaar Tjits , van Bielder Patty 
Published: July 2019

Abstract
Since the academic year 2017–2018, the Tilburg University Language Center has been offering an academic pre-Bachelor’s programme for refugee students. This year-long educational programme prepares high-potential refugees for a Dutch- or English-taught Bachelor’s programme at a university. In addition, students prepare for the Dutch Civic Integration Exams. A special part of the pre-Bachelor’s programme is an internship at a company in the Brabant region. This increases the refugees’ chances on the labour market during and after their studies. In this report, the target group and structure of the programme, the way in which the project is financed, and the experiences of the first pilot year are described. The authors also advocate the importance of an academic language and transition year, explain why this task is best assigned to a university language centre, and make recommendations for institutions that want to set up such a language and transition year themselves.
Ductile-brittle transition temperature shift controlled by grain boundary decohesion and thermally activated energy in Ni-Cr steels
Authors: Kameda Jun , Jokl Martin L. 
Published: July 2019

Abstract
Temper embrittlement induced by segregation of metalloid solutes to grain boundary (GB) was evaluated by a shift of the ductile-brittle transition temperature (DBTT). DBTT was found to be linearly correlated with the amount of metalloid on the GB (X
gb) for both dynamic and static displacement rates (dδ/dt) in high and medium hardness steels. Recent first-principles calculations have determined the GB embrittling potency (Δe
p) of segregated Sb, Sn and P. In both high and medium hardness steels, the slope (α) of DBTT vs. X
gb was found to be linearly dependent on Δe
p regardless of the segregated solutes. In high hardness steels, the slope is independent of dδ/dt, while in medium hardness steels the α is dependent on dδ/dt. An Arrhenius plot of dδ/dt vs. the reciprocal DBTT was used to drive the thermal activation energy (E
act), which represents a barrier to plasticity. It was found that E
act correlates to a reduction in the GB fracture surface energy. The E
act depends strongly on GB decohesion in high hardness steels but only weakly depends on it in medium hardness steels.
Phosphorus – a “political” element for transdisciplinary chemistry education
Authors: Zowada Christian , Gulacar Ozcan , Siol Antje , Eilks Ingo 
Published: July 2019

AbstractThe paper describes a curriculum innovation project for integrating the sustainability-oriented socio-scientific issue of phosphate recovery into undergraduate chemistry education. Justification for the topic is derived from the importance of responsible use of phosphates as fertilizers for achieving some of the sustainable development goals issued by the United Nations in 2015, but also by the consideration of the phosphorus biochemical flow into the environment in the concept of the world’s planetary boundaries. Integration of the topic into undergraduate general chemistry was operated by a digital learning environment providing the base for a transdisciplinary approach towards the topic. Findings are reported from an implementation case in a research university in the USA.
Kitchen chemistry course for chemistry education students: influences on chemistry teaching and teacher education – a multiple case study
Authors: Nuora Piia , Välisaari Jouni 
Published: July 2019

AbstractThis study introduces the Kitchen Chemistry (KC) course and its influences on chemistry education as a whole. KC is considered to be a life-relevant learning environment that engages learners in science through the pursuit of personally relevant and meaningful goals. KC, as a form of interdisciplinary learning, aims to develop boundary-crossing skills and to support the development of pupils’ scientific thinking. The purpose of this research was to determine how KC as a context-based teaching approach applies to chemistry education and what it offers to chemistry teaching and teacher education. We found that KC gave lower secondary school pupils the opportunity to understand the chemical phenomena in a familiar context. Teachers of visiting groups saw that integration is the challenge: pupils often see the subjects of chemistry and home economics as separate entities. The chemistry education students highlighted real-world connections to chemistry concepts and contexts. They also found KC to be an interesting form of teaching chemistry. According to the KC course teachers, the students were motivated and excited, and provided positive feedback on the course. These findings suggest that teachers and teacher education students need to be guided in actively using integration.
A study of the physico-chemical properties of dried maritime pine resin to better understand the exudation process

Published: July 2019

Abstract
The aim of this study was to have a better understanding of the phenomenon of resin exudation on pinewood boards due to the liquefaction of the resin caused by the heat of solar radiation. Resin exudation is a crucial problem for the maritime pine industry, as it may strongly decrease the wood’s aesthetics submitted to outdoor exposure. The softening temperature of dried pine resin was analyzed and the results were examined relative to its physico-chemical properties. To achieve this, resin samples were dried under different conditions (60°C, 120°C during 16 h and at 150°C during 24 h). After 3 months of post-drying at ambient temperature, their softening temperatures were measured by thermomechanical analysis. These same samples were subsequently studied to determine their chemical, structural and morphological properties. Samples with a low drying temperature (60°C) had high opacity attributed to crystallinity and porosity. These elements partially explained a higher softening temperature than for the other samples. Different chemical modifications of resin were also observed due to temperature, with a significant amount of oxidized derivatives for samples dried at low temperature and dehydrogenated compounds for samples dried at high temperature.

Published: July 2019

Abstract
The objective of this study was to reveal a novel mechanism underlying the progression of atherosclerosis (AS) associated with endothelial cells (ECs) and neutrophils. Transmission electron microscopy (TEM) and nanoparticle tracking analysis (NTA) were used to observe the morphology and particle size of isolated exosomes. Western blotting was applied to examine exosomal markers, while the expression of metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) was measured by quantitative real-time polymerase chain reaction (qRT-PCR). The production of inflammatory cytokines and reactive oxygen species (ROS) was determined by an enzyme-linked immunosorbent assay (ELISA) and a dichloro-dihydro-fluorescein diacetate (DCFH-DA) assay. Circulating neutrophil extracellular traps (NETs) were represented by myeloperoxidase (MPO)-DNA complexes. NETs formation was assessed using immunofluorescence microscopy. Atherosclerotic lesion development was measured by Oil Red O (ORO) staining. In the results, MALAT1 expression was increased in exosomes extracted from oxidized low-density lipoprotein (ox-LDL)-treated human umbilical vein endothelial cells (HUVECs). When co-cultured with human neutrophils, exosomes derived from ox-LDL-treated HUVECs were revealed to promote NETs formation, which was mediated by exosomal MALAT1. Furthermore, ox-LDL-treated HUVECs-derived exosomes were demonstrated to trigger hyperlipidemia, inflammatory response and NETs release in a mouse model of AS. In conclusion, exosomal MALAT1 derived from ox-LDL-treated ECs initiated NETs formation, which in turn deteriorated AS.

Abstract
Mo-Ni-B-Al as-cast alloys containing 35.5-58.7 wt% Mo, 23.0-57.6 wt% Ni, 3.3-5.2 wt% B, and 2.2-13.5 wt% Al were synthesized by Self-Propagating High-Temperature Synthesis (SHS) using a mixture of MoO3, NiO, B2O3 and Al powders in order to obtain low-cost Mo2 NiB2 containing hard materials. The first series of experiments were performed using 1.05 times the stoichiometric amount of Al. In the second series of experiments, FactSage thermochemical modeling software was used to minimize Al increasing the Mo2NiB2 formation in the as-cast alloys. The products were characterized by using atomic absorption spectrometry (AAS), X-ray diffraction (XRD), scanning electron microscopy (SEM) and micro-hardness techniques.
Perioperative management of anticoagulant therapy

Published: July 2019

AbstractAbout 10% of patients taking a chronic, oral anticoagulant therapy require an invasive procedure that can be associated with an increased risk for peri-interventional or perioperative bleeding. Depending on the risk for thromboembolism and the risk for bleeding, the physician has to decide whether the anticoagulant therapy should be interrupted or continued. Patient characteristics such as age, renal function and drug interactions must be considered. The perioperative handling of the oral anticoagulant therapy differs according to the periprocedural bleeding risk. Patients requiring a procedure with a minor risk for bleeding do not need to pause their anticoagulant therapy. For procedures with an increased risk for perioperative bleeding, the anticoagulant therapy should be adequately paused. For patients on a coumarin derivative with a high risk for a thromboembolic event, a perioperative bridging therapy with a low molecular weight heparin is recommended. Due to an increased risk for perioperative bleeding in patients on a bridging therapy, it is not recommended in patients with a low risk for thromboembolism. For patients taking a non-vitamin K oral anticoagulant, a bridging therapy is not recommended due to the fast onset and offset of the medication.
Evaluation of the antianxiety and antidepressant activities of mosapride in Wistar albino rats
Authors: Krishna Vybhava , Bairy KL , Patil Navin , Sunny Sweenly V. 
Published: July 2019

Abstract

Background
The 5HT4 receptor agonists are antidepressants with a unique mode of action. Many studies have been done on investigational drugs, and mosapride has been shown to have a 5HT3 antagonistic property. In this study, we assessed the potential anxiolytic and antidepressant effects of mosapride on Wistar albino rats.

Methods
The rats were randomly assigned to two models containing 4 groups of 6 animals each. In the anxiety model, four groups included 0.5 mL of 0.5% carboxymethyl cellulose (CMC), mosapride 1.5 mg/kg, mosapride 3 mg/kg and diazepam 2 mg/kg. They were dosed for 5 days. On the 3rd day, the elevated plus maze (EPM) was conducted, and on the 5th day, the open field (OF) tests were conducted. In the depression model, four groups included 0.5 mL of 0.5% CMC, mosapride 1.5 mg/kg, mosapride 3 mg/kg and imipramine 30 mg/kg. After 3 days of dosing, the forced swim test (FST) was conducted, followed by a washout period of 1 month. Then, the rats were subjected to chronic unpredictable stress with sucrose preference.

Results
Compared with the control, the mosapride-treated animals showed significant anxiolytic behavior at both high and low doses in the EPM and OF tests. In the FST, both high and low doses of mosapride reduced immobility. The climbing behavior was prominent at a high dose of mosapride, whereas swimming was prominent at a low dose. In the chronic stress model, both doses of mosapride preserved sucrose preference comparable to imipramine.

Conclusion
These findings suggest that mosapride has anxiolytic and antidepressant activities at clinically used doses.
