Abstract:
PurposeThis article aims to set a roadmap for an ethical programme, which we call “qualitative migration research ethics” (QMRE). It is a scoping review that maps current ethical challenges that migration scholars often face and provide guidance, while acknowledging the fact that many researchers deal with ethical issues on a case-by-case basis.Design/methodology/approachBy connecting three lines of debates – ethics in social sciences, in qualitative research and in migration studies – this article addresses the following core questions: What are the particular ethical dilemmas in qualitative migration research (QMR)? How do migration researchers deal with these ethical dilemmas? What is the role of universal ethical codes of conduct and case-by-case ethical considerations in dealing with particular situations?FindingsThis review demonstrates that special aspects of migration research context, e.g. participants' mobility, potential vulnerability and migration as a politicized issue as well as the flexible and exploratory nature of qualitative research require particular ethical awareness that cannot be sufficiently addressed by standardized guidelines.Originality/valueIt proposes that efforts to raise ethical awareness must go beyond researchers' ethical confessions or blind adherence to pre-fixed guidance. Researchers must have critical “ethical radar” before, during and after their fieldwork; not only while working on extreme and vulnerable cases but also while doing all kind of research regardless of the level of vulnerability. Last but not least, this article claims the need for including critical ethical consciousness substantially in higher education programmes at the very beginning of the research career.

Abstract:
Research field of migration has been developing for a long time parallel to and outside mainstream institutional academic sociology and its theoretical foundation. In the last two decades, within the field of migration studies, one specific aspect of the phenomena came to the research focus: gender, as significant factor that influences on motivation for migration, shaping, at the same time, its characteristics and specific experiences. With decisive breakthrough of qualitative methods in social sciences and humanities, as well as with gradual development of postmodern philosophy and feminist theory, gender migration studies have been established as research sub-discipline, with its own theoretical and categorical scientific apparatus (as well as institutional-academic grounding), managing more or less successfully to explain and understand multidimensional character of migration processes. This text represents an attempt to make relatively concise overview of disciplines? historical, theoretical and research field development, as a first step in its broader affirmation within Serbian institutional sociology.

Abstract:
This study summarizes US and Japanese historical North Pacific albacore ( Thunnus alalunga) tagging data and uses maximum likelihood methods to estimate seasonal migration rates of young North Pacific albacore. Previous studies related to North Pacific albacore migration have found that the frequency of albacore migrations is difficult to quantify because of inadequate amounts of tags released by the US tagging program in the western Pacific. Use of the combined Japan and US tagging data solves this problem. This study also incorporates specific seasonal migration routes, hypothesized in past qualitative analyses, to avoid overparameterization problems. The estimated migration patterns qualitatively correspond to those from previous studies and suggest the possibility of frequent westward movements and infrequent eastward movements in the North Pacific. This frequent westward movement of young albacore in the North Pacific would correspond to a part of albacore life history in which immature fish recruit into fisheries in the western and eastern Pacific and then gradually move near to their spawning grounds in the central and western Pacific before maturing.

Abstract:
AbstractThis paper examines the experiences of middle class Indian migrants to New Zealand. Using qualitative data from interviews with this under-researched group the paper analyses their migratory strategies, labour market experiences and reasons for choosing New Zealand over other potential destinations. In the New Zealand labour market they experience an under valuation of their Indian qualifications, and interviewees reported taking low level service employment, and only sometimes progressing to middle class forms of employment. In addition, data from the interviews suggests that there is evidence of a ‘brain drain’ from India to New Zealand rather than a circulation of talent that has been the focus of recent theories. Unlike other studies of migration of highly qualified Indian labour this study finds that they are attracted by the environment and family friendly lifestyle of New Zealand as marketed by the New Zealand government to potential immigrants. Contrary to many previous studies, the findings suggest that migration is a family rather than an individual strategy.

ABSTRAKT Hansson, M & Shabdulloeva, H. Migranters erfarenheter av hälso-och sjukvården utifrån olika kulturell bakgrund. En litteraturstudie. Examensarbete i omvårdnad 15 högskolepoäng. Malmö Universitet: Fakulteten för Hälsa och samhälle, Institutionen för vårdvetenskap, 2020. Bakgrund: Under de två senaste decennierna har invandringen ökat markant i Sverige. Detta påverkar alla samhällssystem, och så även hälso- och sjukvårdssystemet. Att ge personcentrerad och god vård är centralt i sjuksköterskans arbete, samt att tillgodose säker och jämlik vård till hela befolkningen. För att uppnå detta krävs det att patienters kultur beaktas i vårdmötet. Syfte: Syftet med litteraturstudien är att beskriva migranters erfarenheter av vården.Metod: En litteraturstudie med kvalitativ ansats baserad på tolv vetenskapliga studier. Studiens fokus var på migranter i vuxen ålder >18år och deras upplevelser och erfarenheter av mötet med vården. Studier som var skrivna efter år 2010 inkluderades. Innehållsanalys användes för att sammanställa resultatet. Resultat: Resultat visar att migranternas erfarenheter av vården påverkades av kommunikationssvårigheter, migranters erfarenheter av bemötande, känslor av utsatthet samt deras egna förväntningar på hälso-och sjukvård.Konklusion: Kulturella skillnader och kommunikationssvårigheter påverkar migranters tillgång till hälso- och sjukvård i det nya landet. För att uppnå målet att ge god och jämlik vård till hela befolkningen krävs det inom vården en medvetenhet om kulturens inverkan på vårdmötet.

Degree Project in nursing 15 credit points, Malmö University: Faculty of Health and society, Department of Care Science, 2020. Background: In the last two decades, immigration has increased significantly in Sweden. It also affects all social systems, including health care. Providing person- centred, good, safe and equal care to the entire population is essential to thenurse’s work. To achieve this, the patients’ culture must be considered in the care meeting. Aim: The literature study aims to describe migrants' experiences of health care. Method: A qualitative literature study was performed based on twelve studies. The focus of the study was on migrants in adulthood > 18 years, their experiences of the encounter with a health care. Studies published after 2010 were included in this review, and content analysis was used to compile the results. Results: The results indicated that immigrants' experience in the health care system was influenced by barriers such as communication, migrants’ experiences of treatment, feelings of vulnerability and expectations of health care.Conclusion: Cultural differences and communication difficulties affect migrants' access to health care in new country. Therefore, the awareness of the cultural impact on the care meeting is required to provide good and equal care to the entire population.

Abstract:
This thesis examines the difficulties encountered in the process of establishing the CommonEuropean Asylum System, taken from a discursive perspective. The focus of the study isthreefold; why are specific issues highlighted by the European Union Member States, how isthe discursive conflict expressed within the discourse on CEAS, and what definitions ofsolidarity are promoted by the Member States. In purpose of addressing these focuses,discourse theory, issue salience and solidarity through burden sharing are used as theoreticalframework. By applying critical method and discourse analysis, this study has managed toestablish that the security issues are among the most highlighted, whereas the geographicallocation of a Member State seems to be an explanatory factor to a Member State’s specificemphasis. Regarding the discursive conflict, the definitions of the concepts mutual trust, fairdistribution and cooperation are especially contested. Furthermore, the external dimension ofsolidarity is proven to be the precedent definition of solidarity.

Doctoral thesis, Uppsala universitet, Institutionen för kvinnors och barns hälsa, 2015. http://urn.kb.se/resolve?urn=urn:nbn:se:uu:diva-259881.

Full text
Abstract:
During the latest decade Somali-born women with experiences of long-lasting war followed by migration have increasingly encountered Swedish maternity care, where antenatal care midwives are assigned to ask questions about exposure to violence. The overall aim in this thesis was to gain deeper understanding of Somali-born women’s wellbeing and needs during the parallel transitions of migration to Sweden and childbearing, focusing on maternity healthcare encounters and violence. Data were obtained from medical records (paper I), qualitative interviews with Somali-born women (II, III) and Swedish antenatal care midwives (IV). Descriptive statistics and thematic analysis were used. Compared to pregnancies of Swedish-born women, Somali-born women’s pregnancies demonstrated later booking and less visits to antenatal care, more maternal morbidity but less psychiatric treatment, less medical pain relief during delivery and more emergency caesarean sections and small-for-gestational-age infants (I). Political violence with broken societal structures before migration contributed to up-rootedness, limited healthcare and absent state-based support to women subjected to violence, which reinforced reliance on social networks, own endurance and faith in Somalia (II). After migration, sources of wellbeing were a pragmatic “moving-on” approach including faith and motherhood, combined with social coherence. Lawful rights for women were appreciated but could concurrently risk creating power tensions in partner relationships. Generally, the Somali-born women associated the midwife more with providing medical care than with overall wellbeing or concerns about violence, but new societal resources were parallel incorporated with known resources (III). Midwives strived for woman-centered approaches beyond ethnicity and culture in care encounters, with language, social gaps and divergent views on violence as potential barriers in violence inquiry. Somali-born women’s strength and contentment were highlighted, and ongoing violence seldom encountered according to the midwives experiences (IV). Pragmatism including “moving on” combined with support from family and social networks, indicate capability to cope with violence and migration-related stress. However, this must be balanced against potential unspoken needs at individual level in care encounters.With trustful relationships, optimized interaction and networking with local Somali communities and across professions, the antenatal midwife can have a “bridging-function” in balancing between dual societies and contribute to healthy transitions in the new society.

Abstract:
In general, immigrants face various problems as they adjust to their new surroundings and begin a new life. The educated, employed Arabic immigrant Muslim women, (EEAIMW), live between two worlds: a Swedish world at work and an Arabic world at home. In this East-West dichotomy, they keep trying to find who they are and where they belong. This thesis helps to understand the influence of the intersection of religion, ethnicity, and gender serving as the primary disadvantage due to cultural expectations, socio-political considerations, and unfavourable stereotypes and stigmatization. This disadvantage affects not only their employment and career advancement, but also the agency and performed identities of EEAIMW in their Swedish workplace, (SWP). The purpose is to give voice to 17 EEAIMW narrating their journey in re-evaluating and developing their religious, ethnic, and gender identities to adapt to the environment of their SWP. Furthermore, to challenge the stereotyping and the stigmatization that position them as the “Other,” impeding their sense of belonging. Comprehensive data concerning the phenomena was gathered through a qualitative research approach and from in-depth semi-structured interviews with the study participants, joined with a literature review on immigrants, Islam, and employed Muslim women, covering topics about identity theories and organizational behaviour. According to the study’s findings, EEAIMW create a place for themselves in their SWP through their diverse agency and identity performing adaptation strategies, and that relationships rather than the place, create a sense of belonging. It is also found that the different sociocultural contexts do not destroy EEAIMW’s religious beliefs but add value to their existence outside their religious aspect. And when representing Swedish society, they remain linked to their homelands.

Abstract:
The case study of this thesis is the analysis of international health care students joined the emergency call of local authorities and performed emergency work during COVID-19 to help the Hungarian health care teams and facilities manage the pandemic. Through this case, the thesis puts an existing student interaction typology (Rose-Redwood and Rose-Redwood, 2013) to the test, and sets out to answer how the COVID-19-induced changes in their typology affected the students’ experience of being a migrant in Hungary. With semi-structured interviews and an inductive approach, the thesis identifies three recurring feelings – isolation, gratitude and responsibility – and the core argument of the thesis is that the feelings and migration experiences that the student shared were connected to the disruption of the student interaction typology. This study informs our understanding of student mobility and helps further research account for atypical situations in student mobility research.

Thesis, Linköpings universitet, Tema Barn, 2018. http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-172691.

Full text
Abstract:
Immigration is a common phenomenon in contemporary society and results in challenges withmaintaining cultural identity while integrating with a new culture. This is particularlyimportant in the family unit, where first-generation immigrant communities may havedifferent levels of experience and cultural values compared to their offspring (Secondgeneration immigrants). Integration in second-generation immigrants is often related tobilingualism and the concept of a dual social identity, embracing elements of host and nativeculture. The aim of this study was to explore the perspective of parents on the role ofbilingualism on integration and identity in their children. A sample of five families, originallyfrom Afghanistan and now living in Sweden, was purposively selected to complete semistructured interviews exploring bilingualism, social identity and integration. The findings ofthese interviews revealed three key themes relating to the adoption of Swedish identity bychildren, the loss of Afghani identity, and the role of the school and society in facilitatingthese identities.Overall, the interview data suggested that children living in Sweden identified as Swedish andengaged in cultural and social activities consistent with integration. Bilingualism was animportant aspect of holding a largely Swedish identity, although parents valued dual identityof children. Often, immersion in Swedish culture and limited opportunities to socialise as anAfghani cultural unit were viewed as threats to maintaining or developing a clear Afghaniidentity. The role of schools, parents and society in general is considered important in theseprocesses, particularly with regards to supporting cultural and religious values of the familyunit, while promoting successful integration. Bilingualism was universally viewed as apositive tool that could facilitate integration and dual identity, where suitable opportunitiesarose.

Full text
Abstract:
Europe is living a process of internalisation: the EU policies toward new economic agreements and visa regimes have increased transnational migrations, and have affected the way national borders are understood (Silverstein, 2005:376)⁠. Besides, social researchers have highlighted the active role of children (see e.g. Ryan et al., 2008), who seem to influence the migration process of the parents in the receiving country and make the experience of migrant parents a focus of interest. This qualitative research focuses on parents living in Germany, exploring their talks about parenting practices in a migration context. For this, five Spanish mothers living in Berlin and Munich are interviewed, and their discourses are analysed using the thematic analysis presented by Braun & Clarke (2006). The study exposes the following themes: the perceived national differences in child rearing and family care; the cultural heritage and presence of the Spanish language and culture in the parenting practices; and the experience of care delegation in the foreign country. It also comments on the perceived influence of children in the migration process of the participants. The study concludes on the significant presence of the origin language and culture in the parenting practices of the participants and the great influence that having children has had in the in their migration experience. The presence of children affects the relation to their own culture and language, their opinions towards the welfare system and culture of Germany, and their social life and further permanence in the receiving country.

Full text
Abstract:
This dissertation investigates how Jewish women social scientists relationally established their gendered-racialized subjectivities and theories about race-gender-sexuality-class through their portrayals of black women’s sexuality and family structures in the African Diaspora: the U.S., Brazil, South Africa, Swaziland, and the U.K. The central women in this study: Ellen Hellmann, Ruth Landes, Hilda Kuper, and Ruth Glass, were part of the same “political generation,” born in 1908-1912, coming of age when Jews of European descent experienced an ambivalent and conditional assimilation into whiteness, a form of internal colonization. I demonstrate how each woman’s familial origin point in Europe, parental class and political orientations, were important factors influencing her later personal/professional networks and social science theorizing about women of color. However, other important factors included the national racial context, the political affiliations of her partners, her marital status and her transracial fieldwork experiences. One of the main problems my work addresses is how the internal colonization process in differing nations within the Jewish diaspora differently affected and positioned Jewish social scientists from divergent class and political affiliations. Gendering Aamir Mufti’s primarily male-oriented argument, I demonstrate how Jewish internal divergences serve as an example that highlights the lack of uniformity within any “identity” group, and the ways that minority groups, like Jews, use measures of “abnormal” gender and sexuality, to create internal exiled minorities in order to try to assimilate into the majority colonizing culture. My dissertation addresses three problems within previous studies of Jewish social scientists by creating a gendered analysis of the history of Jews in social science, an analysis of Jewish subjectivity within histories of women (who were Jewish) in social science, and a critique of the either-or assumption that Jewishness necessarily equated with a “radical” anti-racist approach or a “colonizing” stance toward black communities. The data collection followed a mixed methods approach, incorporating archival research, ethnographic object analysis, site visits in Brazil and South Africa, consultations with library, archive and museum professionals, and interviews with scholars connected to the core women in the study.

Abstract:
The definition of data in qualitative research is expanding. This book highlights the value of embodiment as a qualitative research tool and outlines what it means to do embodied research at various points of the research process. It shows how using this non-invasive approach with vulnerable research participants such as migrant, refugee, and asylum-seeking women can help service users or research participants to be involved in the co-production of services and in participatory research. Drawing on both feminist and post-colonial theory, the author uses her own research with migrant women in London, focusing specifically on collage making and digital storytelling, whilst also considering other potential tools for practicing embodied research such as yoga, personal diaries, dance, and mindfulness. Situating the concept of ‘embodiment’ on the map of research methodologies, the book combines theoretical groundwork with actual examples of application to think pragmatically about intersectionality through embodiment.

Abstract:
Abstract Poland coped well with the worldwide economic crisis and refugee challenge. However, studies show that the crisis did in fact exist, and the state’s poor response to it was reflected in the citizens who bore its brunt. As for migration, polarised public discourse and the attitude of the government resulted in social tension, including extreme right-wing parties mobilising citizens around migration issues. In this chapter, using qualitative data from the TransSOL project, the authors answer the following question: How have crises and other changing circumstances affected organised solidarity in different social fields, namely unemployment, migration and disability? The chapter argues that, according to the theory of the economic recession’s impact on multidimensional solidarity due to the austerity measures, or the Polish government’s inaction, social solidarity did emerge, but in unforeseen ways and fields.

Abstract:
AbstractExtreme climate change events such as frequent and prolonged droughts or floods associated with climate change can be very disruptive to peoples’ livelihoods particularly in rural settings, where people rely on the immediate environment for livelihood. Shocks in the people’s livelihoods can trigger diverse responses that include migration as a coping or adaption strategy. Migration takes many forms depending on the context and resources availability. Very few studies in Kenya have used qualitative analysis to bring up women’s voices in relation to gender, climate change, and migration, especially along hydrological gradient. This chapter presents results of qualitative research conducted from 58 participants in 2018 in three counties in Kenya, namely, Kiambu County, Machakos, and Makueni. The study sought to examine gender perceptions related to climate-induced migration, that is: whether climate change is perceived to be affecting women’s livelihood differently from that of men; examine in what ways experiences of climate induced migration differed for men and women; explore perceptions on the county government efforts to cope with climate-induced migration; and examine perceptions of the role of nongovernmental agencies in helping citizens cope with climate change. From the results obtained on ways in which climate change affected women livelihoods more than men had four themes: (1) women exerted more strain in domestic chores, child/family care, and in the farm labor; (2) women also experienced more time demands. The sources of water and firewood were getting more scarce leading to women travel long distances in search to fetch water and firewood; (3) reduced farm yields, hence inadequate food supply; and (4) the effects of time and strain demands on women was a contributory factor to women poor health and domestic conflicts. Several measures that the county government could take to assist women to cope with climate change-induced migration had five themes which include the following: (1) developing climate change mitigations, and reducing deforestation; (2) increasing water harvesting and storage; (3) develop smart agriculture through the use of drought-resistant crops and drought mitigation education; (4) encourage diversification of livelihoods; and finally (5) providing humanitarian assistance to the most vulnerable populations such as orphans and the very poor. Thirdly, the measures mentioned that NGO’s could take to assist rural communities to cope with climate change-induced migration did not vary significantly from those mentioned for county government, except probably for a new theme of increasing advocacy for climate adaption policies.

Abstract:
AbstractExtreme climate change events such as frequent and prolonged droughts or floods associated with climate change can be very disruptive to peoples’ livelihoods particularly in rural settings, where people rely on the immediate environment for livelihood. Shocks in the people’s livelihoods can trigger diverse responses that include migration as a coping or adaption strategy.

Abstract:
AbstractIn this chapter I draw on my fieldwork experience in Los Angeles to discuss the potential of video for qualitative research on migration and political action. I focus specifically on three aspects: access to the field, research respondents and data; video and the study of micro-social interaction; video as a tool to generate new insights and data. I argue that video has facilitated, enriched and expanded my understanding of migrant political action in several ways, some of which were entirely unexpected at the beginning of this research. Within the field of migration studies, video appears particularly suitable to research the terrain of politics and culture, since it provides the means to study a key social aspect that is difficult to investigate in detail only with other types of methods: interaction. Hence, video as both a tool and a method proved a useful complement to interviews, artefacts and archive documentation.

Abstract:
Abstract This chapter studies the relationships and interaction among the Latvian emigrants from different migration waves in the United States. It specifically examines reasons for the inability of the existing and politically and culturally active Latvian diaspora community in the United States to integrate newcomers from Latvia. The diaspora community is formed mostly of migrants who left Latvia after World War II. The research is based on a mix of two sources of information and methods – qualitative analysis of in-depth interviews with the ‘new’ Latvian emigrants in the United States in 2014, who began arriving there in 1991 and quantitative data analysis of The Emigrant Communities of Latvia survey. The study illustrates that the migrants from the most recent emigration wave distance themselves to a large extent from the previous migration wave. Additionally, the most recent migrants do not have strong social ties or active networks with Latvians back home and, therefore, cannot be considered as being a part of a transnational community, which is a characteristic of the previous Latvian migration wave. Instead, the migrants from the most recent wave base their belonging on the notion of having roots in Europe in terms of cultural heritage and identity. For this reason, they are to be considered as so-called ‘nomadic’ migrants, although this differs substantially from the way the concept is used in the academic literature so far – there is no return point back home, as they only look forward.

Abstract:
AbstractThis chapter analyses the relationship between migration and social mobility in Argentina and Spain from a transnational perspective focusing on two dimensions: the patterns of intergenerational social mobility of immigrants and natives in both countries; the social mobility strategies and trajectories of Galicians families in Buenos Aires and Argentinians, of Galician origin, who migrated to Galicia after the 2001 crisis. The chapter begins by contextualizing the migratory trends in Europe and Latin America. This is followed by a comparative study of how immigration impacts on the class structure and social mobility patterns in Argentina and Spain. Quantitative analysis techniques are used to study the intergenerational social mobility rates. The statistical analysis of stratification and social mobility surveys have been benchmarked against previous studies conducted in Argentina (Germani, G., Movilidad social en la sociedad industrial. EUDEBA, Buenos Aires, 1963; Dalle, P., Movilidad social desde las clases populares. Un estudio sociológico en el Área Metropolitana de Buenos Aires (1960–2013). CLACSO/Instituto de Investigaciones Gino Germani-UBA/CICCUS, Buenos Aires, 2016) and Spain (Fachelli, S., & López-Roldán, P., Revista Española de Sociología 26:1–20, 2017). Secondly, qualitative research methods are used to consider the social mobility strategies and class trajectories of migrant families. We analyse two fieldworks, developed in the framework of other research projects (based on 44 biographical and semi-structured interviews). These case studies were carried out with Galicians that migrated to Argentina between 1940 and 1960 and Argentinians, of Galician origin, who migrated to Galicia after the 2001 crisis.

Abstract:
Intermediate filaments (often abbreviated as IFs), in addition to microtubules and microfilaments, are one of the three major components of the cytoskeleton in eukaryotic cells (Figure 1). It has been suggested that intermediate filaments are crucial in defining key mechanical functions of cells such as cell migration, cell division and mechanotransduction, and have also been referred to as the “safety belts of cells” reflecting their role in preventing exceedingly large cell stretch [1, 2]. Vimentin is a specific type of this protein filament found in fibroblasts, leukocytes, and blood vessel endothelial cells, representing the most widely distributed type of intermediate filaments. Several diseases have been linked to the structure and density of intermediate filaments. Here we report a systematic study of the effects of intermediate filaments on cell mechanics, specifically focused on changes in the density of filaments. We compare the results with experimental studies in vimentin deficient cells, showing good qualitative agreement.

Abstract:
It is becoming increasingly evident, that of the signaling modalities relevant to the cell-extracellular matrix (ECM) microenvironment, the mechanical component is a very important mediator of cell behavior (reviewed in [1, 2]). Indeed, proliferation, ECM protein expression (collagen), matrix metalloproteinase (MMP) levels, migration, and stem cell differentiation, have all been shown to be affected by mechanical environmental cues [3, 4]. Although the importance of physical signaling mechanisms has been well established, the bulk of this work has yet to be translated to a more physiologic 3D microenvironment [1]. Self-assembling collagen matrices provide a biochemically, biophysically relevant 3D model of soft tissues in which biomechanical studies can be performed [5, 6]. It is with this 3D tissue model in mind, that a biaxial mechanical testing system (BMTS) was devised, built, tested, and applied to the study of cell-ECM biomechanics. The completion of this device has enabled us, to undertake a multi-scale, multidimensional study of cell-ECM mechanics. Hierarchical quantification of cell and ECM strains using digital image correlation (DIC) facilitate a more complete understanding of the mechanical response of cells to macroscopic loads and deformations. Furthermore, transfection of cells with GFP tagged actin binding protein utrophin (UTR-GFP) enables qualitative assessment of cytoskeletal deformations [7].

Abstract:
During the last three years, we could detect hereditary quantitative protein C (PC) deficiency in 43 patients belonging to 18 families. In those defects type I without oral anticoagulant treatment, the values of PC measured either by an ELISA method (PC:Ag) or by a chronometric functional assay were very closed and well correlated. (Results expressed in % of normal pooled plasmas PC:Ag m=44,l %, SD = 15,3 ; PC : activity m = 49,5, SD = 13,5 - correlation r = 0,82). In a 32 year#old man with a severe thrombo-embolic disease and in 11 related people, we could diagnose a hereditary qualitative PC deficiency type II, because of a discrepancy between normal PC:Ag levels (m = 105 %, SD = 20,3, range = 78-143) and low PC anticoagulant activities (m = 46 %, SD = 9,5, range = 30-60). FunctionalpC studies included assays, with or without preliminary adsorption on baryum citrate or aluminium hydroxide, with various PC activators (thrombin, PROTAC venom), in chronometric and amidolytic assays.(Normal protein S levelswere first tested).As shown by those results, PC activity is normal in amidolytic assays even after preliminary adsorption whatever the activation is. On the contrary, the PC anticoagulant activity is reduced in any technique. We can conclude that the activation is normal. Crossed immunoelectrophoresis (CIE) with or without calcium showed normal migration as compared to controls. Normal adsorption on insoluble salts and normal Ca-binding in CIE allow us to say that the abnormal PC is not completely acarboxylated. As amidolytic assays (normal in patients) do not assess the ability of activated PC to interact with protein S (PS) and phospholipids via calcium, 3 hypothesis can explain the functional abnormality:- abnormal binding to PS- abnormal binding to phospholipids due to partially carboxylated glutamic acids (which would be sufficient to promote adsorption)- defective inhibition of Va and Villa because a conformational change allowing only hydrolysis of little synthetic peptides.

Full text
Abstract:
Human capital is an economic category which is increasingly applied in the models of economic growth and development. Many studies have demonstrated its positive effect on economic development at the national and regional levels. The level of development of rural areas is also strongly correlated with the human factor. The objective of the study was to carry out a quantitative and qualitative diagnosis of the situation of human capital across rural areas in Poland and to indicate the main challenges associated with the shaping of this capital in the context of economic growth simulation. The method used to meet the objective was a review of source literature and an analysis of statistical data from the Central Statistical Office (GUS) with the application of dynamics and structure indices. In the course of research, it was established that the main trends affecting the situation of human resource capital across rural areas in Poland are: the ageing of the rural population, as a dominant negative trend, and a systematic, though slow, increase in the level of education, as a dominant positive trend. It was determined that unfavorable demographic transformations of rural communities involve the risk of limiting economic activities of the elderly, and at the same time, also a decrease in their economic independence and an increase in the social burden resulting therefrom. On the other hand, the observed rise in the level of education and economic activity may accelerate the beneficial transformations of the area structure of agricultural farms, for it contributes to the acceleration of migration of the rural population to other, non-agricultural professions. In this context, taking actions, both nationally and regionally, aiming at increasing qualifications of rural (including agricultural) populations constitutes a vital opportunity, which increases intellectual potential and competitiveness across the country and its individual regions.

Full text
Abstract:
Non-axisymmetric end wall profiling is now a well established design methodology in axial flow turbines, used principally to improve their aerodynamic efficiency by reducing secondary loss. However, profiled end walls (PEWs) have yet to find an in-service application in a gas turbine compressor. This two-part paper presents the results of a number of studies, both experimental and computational, into the potential aerodynamic benefits of applying PEWs in axial flow compressors. The first paper reports research carried out using a linear compressor stator cascade at Cambridge University. The datum geometry was based on previous research with this cascade. The PEW geometry was generated using a method that had been proven to reduce secondary loss in turbine blade rows. Data was taken on the datum and PEW geometries in the form of exit area traverses and surface static pressure measurements. The experiments demonstrated improvements to the exit flow field in terms of local reductions in the loss and under-turning in the secondary flow region due to the PEW. It was found that the original design method had over estimated the benefits of the PEW. The datum and PEW geometries were further analysed using state-of-the-art CFD (Computational Fluid Dynamics). The CFD is shown to achieve very good agreement with measurement at the design condition and a reasonable, qualitative match at off-design. It is concluded that the PEW geometry, though not optimum, effected predictable changes to the compressor stator flow field. The mechanisms for these effects are discussed and conclusions are drawn for taking the work forward. In particular, a mechanism is identified whereby the PEW enhances the cross-flow on the end wall and the subsequent radial migration of the secondary flow adjacent to the aerofoil suction surface. The control of corner stall by means of this flow mechanism is highlighted as a possible area for further investigation. This is followed up in the second paper, which presents a computational study of applying PEWs to a multi-stage HP compressor.

Abstract:
A new heat transfer model for stratified flow boiling in a horizontal tube is proposed in this present study. In recent years, the subject of nonlinear dynamics has progressed and various tools of analysis have been proposed for complex systems. Coupled Map Lattice (CML) method is one such tool which makes it possible to simulate complex systems and to capture the qualitative nature of the phenomenon. In this work, steady stratified flow boiling of water is simulated qualitatively by using the CML model for laminar, hydrodynamically and thermally developing flow and heat transfer in a horizontal tube. The liquid enters in a constant wall temperature tube (Tw*>Tsat* at Pentrance*) in a subcooled or saturated condition. The present modeling by CML is based on the assumption that the flow boiling is governed by nucleation from cavities on the heated surface, migration of vapor into the core, forced convection and phase change in the bulk. The macroscopic variable chosen is temperature. The influences of mass flow rate, inlet subcooling and wall temperature have been studied. The results of the computations provide information on the effect of aforementioned parameters on the heat transfer coefficient and void fraction. The results show that the CML has been able to model flow boiling in a realistic manner.

Full text
Abstract:
The Ultra Compact Combustor (UCC) has shown viable merit for significantly improving gas turbine combustor performance. UCC models for small engines can provide centrifugal loading up to 4,000 gs. However, as the scale of the combustor increases, the g-load will necessarily decrease and the radial vane height will increase. Thus, the importance of understanding flame migration over increasing radial vane heights is pivotal to the applicability of this design to larger engine diameters. The Air Force Institute of Technology’s Combustion Optimization and Analysis Laser laboratory studied this effect with a sectional UCC model using three different vane heights. By varying the mass flow rates of the circumferential UCC section, the g-loading was varied from 500–2,000 gs. Two-line Planar Laser Induced Fluorescence at 10Hz was used for 2D temperature profiles. High-speed video at 2kHz was also used for qualitative flame migration characterization. Several cases were studied varying the radial vane height, the circumferential g-load, and the UCC/core mass flow ratio but specifically focusing on the interaction between matching the core mass flow and the core freestream velocity among the different vane heights. Finally, the decreased core flow velocity for the same mass flow weakened the shear layer between the main and cavity flows and this allowed deeper flame migration into the core flow from the UCC. Control of the overall flame migration is the key to produce desirable combustor exit temperature profiles. Increased spans lead to higher velocity gradients and increased flame injection angles at the same mass flow rates. However, at the same core flow velocities and UCC to core flow velocity ratios the flame injection angle was relatively independent of the radial vane height and almost entirely dependent on the core flow velocity alone.

Full text
Abstract:
The effect of hub leakage flow on the performance of two high speed transonic rotors is investigated through numerical simulations and experiments. The leakage flow emanates from a small gap between the stationary and rotating parts of the hub flow path upstream of the rotor. Results of both the experiments and CFD simulations show that the introduction of a small leakage flow (0–25% of the main passage flow) can reduce the total pressure rise produced by the rotor across the entire span and generate a significant deficit in the total pressure profile near the hub. Numerical simulations done with a sinusoidal distribution of the leakage flow across the rotor pitch show that this deficit is present even when there is zero net leakage. Particle tracer studies of CFD simulations show that this deficit is due to the flow blockage produced by the radial migration of the low momentum leakage fluid. The performance degradation trends predicted by the simulations are qualitatively confirmed in the experimental investigation.

Abstract:
Abstract Modern gas turbines present important temperature distortions in the core-engine flowpath, mainly in the form of hot and cold streaks imputed to combustor burners and components cooling systems. As they highly influence turbines performance and lifetime, the precise knowledge of the thermal field evolution through the combustor and the high-pressure turbine is fundamental. The majority of past studies investigated streaks migrations directly examining the thermal field, while a limited amount of experimental work employed approaches based on the detection of tracer gases. The latter approach provides a more detailed evaluation of the evolution and mixing of the different flows. However, the slow time response due to the employment of sampling probes and gas analysers make the investigation of a whole measurement plane extremely time consuming. To tackle this issue, in this study a commercial oxygen sensor element and its excitation/detection unit were integrated into a newly developed probe to carry out local tracer gas concentration measurements exploiting the fluorescence behaviour. The probe was provided with a Kiel-like shield, a pressure port and a thermocouple, in order to correct the readings in case of 3D flows with pressure, temperature and velocity gradients. The paper summarizes the probe development and calibration activities, with the characterization of its accuracy for different flow conditions. Finally, two probe applications are described: firstly the probe was used to detect tracer gas concentrations on a jet flow; afterwards it was traversed on the interface plane between a non-reactive, lean combustor simulator and the NGV cascade. The probe has proven to provide accurate and reliable measurements both from a quantitative and qualitative point of view even in highly 3D flow fields typical of gas turbines conditions.

Abstract:
MnCo2O4 spinel coatings are designed to be used on metallic interconnectors in SOFC devises to decrease oxidation rate of the metallic interconnect and to prevent the evaporation of harmful CrO3 and Cr2(OH)2 compounds. These Cr-compounds degrade the long-term performance of the SOFC by migrating to the triple phase barrier (TPB) of the cathode and reduce back to Cr2O3. MnCo2O4 spinel coatings, used in this study, were manufactured by using a novel solution precursor plasma spray (SPPS) process and heat treated in oxidizing environment. Deionized water based solutions of Mn(NO3)2•4H2O and Co(NO3)2•6H2O were used as a feedstock material. Concentration of the metal cations in the solutions was adjusted to 3 M. Ferritic stainless grade Crofer 22 APU with the thickness of 0.5 mm and surface roughness of Ra < 0.5 μm was used as a substrate material. The coatings were manufactured using a Sulzer Metco A3000S plasma spray system with F4-MB plasma gun with modified solution feeding hardware. Coatings with different microstructures were sprayed using different spraying parameters, e.g. the type of plasma gases used. The as-sprayed coatings were aged at 700 °C for 500 h in oxidizing environment, in order to study the stability of the coating, the growth of the Cr-scale and the Cr-transport through the spinel coatings. The microstructural characterization for the as-sprayed and the oxidized coatings were done using a field-emission scanning electron microscopy (FESEM) with SE-mode. The quantitative analyses were executed with energy dispersive spectroscopy (EDS), and in addition X-ray diffraction (XRD) was used for qualitative studies. The coatings with various microstructures were sprayed. The densest microstructure was sprayed using Ar-He plasma gas. Also the crystallographic equivalence for MnCo2O4 was achieved when Ar-He plasma was used with 40 mm spraying distance. Ageing caused the increase in structural porosity. On the interface between the coating and the interconnect, a dense spinel layer was formed which effectively prevented the Cr-transport forming approximately 500 nm thick Cr-rich sub-scale.
