Abstract:

Eir ati yn y traethawd hwn i ymdrin â delwedd yr aelwyd yn y nofel Gymraeg o 1960 hyd at 2008 trwy gyfrwng ymdriniaeth thematig. Yn y bennod gyntaf, amlinellir nodweddion o gefnlen gymdeithasol yr ugeinfed ganrif a oedd yn gatalyddion i’r aelwyd hanesyddol, ac i ddarlun yr aelwyd ffuglennol. Yn yr ail bennod, edrychir ar ddarlun delfrydol yr ‘aelwyd draddodiadol Gymreig’ mewn llenyddiaeth ar ddechrau’r ugeinfed ganrif. Yn ail ran y bennod, ystyrir i ba raddau yr arddelir y darlun o’r ‘aelwyd draddodiadol Gymreig’ mewn testunau a gyhoeddwyd rhwng 1930 a 1960. Yn y drydedd bennod, dechreuir ar y brif astudiaeth gan roi sylw i’r aelwyd argyfyngus. Ymdrinnir â delwedd yr aelwyd mewn nofelau a gyhoeddwyd yn ystod y chwedegau a’r saithdegau lle gwelir newidiadau cymdeithasol pellgyrhaeddol y blynyddoedd hynny ynghyd â’r chwyldro rhywiol yn gefnlen amlwg i’r nofelau. Yn y bedwaredd bennod, eir ati i ymdrin ag aelwyd plentyndod. Gan ganolbwyntio ar nofelau lle defnyddir llif meddwl y plentyn fel naratif, dehonglir y ddelwedd a roddir o’r aelwyd gan y plentyn ei hun. Sonnir am y plentyn fel traethydd eironig wrth iddo ddatgelu gwybodaeth am yr aelwyd nad yw’n deall ei harwyddocâd. Yn y bumed bennod, ceir ymdriniaeth gymharol ag aelwyd y wlad ac aelwyd y ddinas. Dehonglir yr aelwydydd yng ngolau traddodiad a Chymreictod ar y naill law, a modernrwydd a Seisnigrwydd ar y llall. Amlygir yr aelwyd wledig fel alltud i’r newidiadau cymdeithasol a effeithiodd ar ffyniant proffesiynol y ferch, a’r aelwyd ddinesig fel un a’u croesawodd. Yn y chweched bennod, eir ati i ymdrin â’r aelwyd amgen (gwahanol/alternative). Ceir yma aelwyd ffuglennol sy’n gwyro oddi wrth yr hyn a ystyrir yn gonfensiwn. Caiff cysyniad traddodiadol yr aelwyd ei herio, a gofynnir: a oes rhaid wrth adeilad er mwyn creu aelwyd?

Abstract:

El objetivo de la investigación fue Proponer un rediseño organizacional para la Empresa H y D Construcciones en General E.I.R.L en el año 2014-2015. El tipo y diseño de la investigación es cualitativa y descriptiva respectivamente; por lo que el instrumento a aplicar en el presente estudio es la entrevista. Por lo que se obtuvo como resultado: que la empresa H y D carece de organigramas formales que muestren gráficamente los diferentes niveles de autoridad, los canales formales de comunicación, las líneas de autoridad y responsabilidad, se tiene como consecuencia que los empleados no se ubiquen jerárquicamente, lo que da como resultado la dualidad de funciones y mando. Por otro lado no existe un manual de organización y funciones formal. Actualmemte se cuenta con 48 trabajadores, los cuales se desempeñan en diferentes puestos de trabajo. Las funciones de la gerencia general, son en base a declaraciones vertidas en la entrevista aplicada, pero no de manera formal definitiva; las funciones de los trabajadores dentro de H y D son: supervisar, controlar, dirigir y organizar la obra asignada, sin embargo también coordinan avances de obra con la supervisión de la obra la cual, tienen que dar cuentas de los avances de acuerdo al plano oficial. Finalmente se concluye que en la empresa Constructora H y D Construcciones en General E.I.R.L los trabajadores perciben desorden administrativo y ausencia de gestión por procesos y tiene pocos competidores en el mercado de instalaciones de redes contraincendios; motivo por el cual se pueden generar nuevas innovaciones en este mercado.

Abstract:

The expression of the Drosophila melanogaster morphogen Hedgehog (Hh) plays a key role in co-ordinating proliferation and differentiation during animal development. Tight spatial and temporal regulation of Hh expression is essential for its correct function in these essential processes. Both mis-expression of its mammalian orthologue Sonic Hedgehog (Shh) and aberrant stimulation of the associated signalling pathway occur in a wide range of human tumours. Although there is extensive knowledge of the signal transduction pathway that is activated in a Hh-stimulated cell, very little is known about pathways governing the expression of the morphogen itself. The Drosophila tumour suppressor protein Hyperplastic Discs (Hyd), an E3 ubiquitin ligase, negatively regulates hedgehog (hh) expression and Hh pathway activity by independent mechanisms in the developing Drosophila eye. Genetically generated hyd mutant clones in the eye mis-express hh and the transcriptional activator of Hh target genes, Cubitus interruptus (Ci), and cause overgrowth of the surrounding wildtype tissue. However, the underlying molecular mechanism(s) by which Hyd regulates these morphogen regulatory pathways is not known. Hyd may be involved in ubiquitylating target proteins in these pathways, which could have degradative or non-degradative outcomes. In order to elucidate Hyd’s molecular role in potential morphogen regulatory pathways, I applied a proteomics-based approach to identify novel Hyd binding partners and ubiquitylated substrates. Tandem affinity purification in combination with mass spectrometry was used to purify and identify Hyd and its complexed binding partners from Drosophila cells. Binding and ubiquitylation assays were subsequently used to verify and characterize the interactions. In addition, a biased, literature-guided approach was applied to identify likely Hyd binding partners based on their involvement in morphogen signalling and conservation across species. Finally, to assess the functional consequences of a newly identified interaction, I used a Drosophila in vivo model to determine whether the novel binding partner was capable of modifying the hyd mutant phenotype. For this purpose, the Mosaic Analysis with a Repressible Cell Marker (MARCM) technique was used to generate hyd mutant clones in the developing larval eye, which were expressing transgenes resulting in either the over-expression or RNAi-mediated knockdown of the gene of interest. My results indicate that Hyd is involved in regulating both Hh and Wg morphogen signalling in the Drosophila eye, and that the molecular mechanism of action may, at least in part, involve the protein kinase Shaggy (Sgg). Hyd interacts with the Hh and Wg transcriptional activator proteins Ci and Armadillo, respectively, as well as the Sgg kinase. Sgg is a negative regulator of both the Hh and Wg pathways, and acts to direct the proteolytic processing or degradation of the transcriptional effectors of these morphogen pathways. Sgg and its mammalian orthologue GSK3β were ubiquitylated in vitro, and GSK3β ubiquitylation was negatively regulated by the mammalian homologue of Hyd, EDD. Knockdown of sgg in eye disc cells mutant for hyd resulted in a dramatic rescue of the overgrowth phenotype. Loss of hyd in clones located in the anterior region of the eye disc resulted in low levels of the full-length Hh transcriptional activator protein Ci. This effect was reversed completely as a result of sgg knockdown. Furthermore, loss of hyd in eye disc clones resulted in elevated Hh and Wg morphogen expression. Mis-expression of hh in hyd mutant clones was significantly reduced upon over-expression of a constitutively active Sgg kinase. Hence sgg appears to genetically act downstream of hyd to regulate hh gene expression and Ci expression. In summary my results identify Sgg as a novel regulator of hh gene expression, whose activity may be regulated by ubiquitylation, and which may be acting downstream of Hyd in a ubiquitin-regulated manner to control both hh gene expression and Hh pathway activity in the developing Drosophila eye. Hyd may also regulate Hh pathway activity by directly interacting with Ci and affecting its activity. The results also indicate that Hyd may be a master regulator of both Hh and Wg morphogen signalling during Drosophila development.

Abstract:

De nombreuses protéines possèdent des cofacteurs inorganiques contenant des métaux de transition. Les propriétés physico-chimiques de ces métaux permettent aux enzymes qui les portent de catalyser des réactions impossibles par l'utilisation des seules potentialités chimiques des vingt-deux acides aminés. Cependant, ces métaux sont toxiques pour la cellule lorsqu'ils sont libres. La synthèse et l'incorportion de ces cofacteurs dans les enzymes nécessitent alors des machineries protéiques complexes d'assemblage. Au cours de cette thèse, les mécanismes de synthèse des centres FeS par les machineries ISC (Iron-Sulfur Cluster) et Hyd (Hydrogenase) ont été étudiés. Le système ISC correspond à la machinerie primaire d'assemblage des centres FeS chez les bactéries, et un système équivalent existe chez les eucaryotes au niveau de la mitochondrie. Le système Hyd est la machinerie de maturation de l'hydrogénase à FeFe chez plusieurs eucaryotes inférieurs (algues et protistes) et dans une grande variété de bactéries. Dans un premier temps, nous nous sommes intéressés à la machinerie ISC d'Archaeoglobus fulgidus dont le coeur est composé de la cystéine désulfurase IscS et de la protéine échafaudage IscU ; IscS apportant le soufre nécessaire à l'assemblage du centre FeS sur IscU. Au cours de cette étude, il est apparu que IscS d'Archaeoglobus fulgidus ne possède pas d'activité cystéine désulfurase, mais qu'elle joue tout de même un rôle fondamental dans la synthèse du centre FeS sur le complexe IscSU en fournissant sa cystéine active en tant que ligand de l'agrégat. Dans un second temps, nous avons étudié la protéine à radical S-adénosyl-L-méthionine HydG, responsable de la synthèse des ligands CN- et CO du sous-agrégat à 2 Fe des hydrogénases à FeFe, qui était la seule maturase du système Hyd dont la structure n'était pas connue. Nos résultats structuraux et fonctionnels suggèrent que HydG synthétise successivement le ligand CN- dans un site actif basique, puis le ligand CO sur le cinquième Fe de son agrégat [5Fe-4S] C-terminal. Ce dernier pourrait être stabilisé par un ligand cystéine ou homocystéine
Many proteins have inorganic cofactors containing transition metals. The physicochemical properties of these metals allow the enzymes, which carry them to catalyze reactions not possible when only using the chemical properties of the twenty-two amino acids. However, these metals are toxic to the cell when they are free. Consequently, the synthesis and incorporation of these cofactors into enzymes requires complex protein assembles. In this thesis, the FeS clusters synthesis mechanisms by the ISC (Iron-Sulfur Cluster) and Hyd (Hydrogenase) machineries were studied. The ISC system corresponds to the primary FeS clusters assembly machinery in bacteria, and a homologous system exists in mitochondria. The Hyd system is FeFe-hydrogenase active site maturation machinery found in several lower eukaryotes (algae and protists) and in a wide variety of bacteria. Initially, we studied the ISC machinery from Archaeoglobus fulgidus whose core is composed of the cysteine desulfurase IscS and the scaffold protein IscU; IscS delivers the sulfur needed for the FeS assembly to IscU. From this study we conclude that IscS from Archaeoglobus fulgidus has no cysteine desulfurase activity, but it still plays a fundamental role in FeS cluster synthesis by IscSU complex by providing a cysteine ligand to the nascent cluster. Secondly, we studied the radical S-adenosyl-L-methionine HydG, responsible for the synthesis of CN- and CO ligand of the active site [FeFe] subcluster, which was the only Hyd system maturase for which the structure was unknown. Our structural and functional results suggest that HydG successively synthesizes the CN- ligand at a basic site, and then the CO ligand at the unique fifth Fe ion of its C-terminal [5Fe-4S] cluster. The latter could be stabilized by either a cysteine or a homocysteine ligand

Abstract:

In this study the relationships among the land use and soil types in the entire river basin as well as in the buffer strip on the one hand, and the Lithuanian river water quality physico-chemical parameters on the other hand have been identified. The spatially based Factor analysis has been tested on river hydrochemical data from 108 sites for the period of 1999-2004. The Factor analysis enabled the identification of the main natural and anthropogenic processes (factors) determining water quality during each season of a year. As a result, monitoring stations were grouped into clusters each representing a group of stations mostly affected by a relevant factor. In addition, the suitability of world-wide used diatom-based water status assessment methods to apply under Lithuanian conditions has been assessed. The results of established water quality determining factors and the tested multivariate statistical procedures can be applied in practice when the reasons for water quality impairments are to be investigated or river monitoring network is to be optimized. The results reveal that Wastewater factor is prominent in small rivers downstream larger towns; Agro-geological factor – in northern Lithuania‘s rivers of heavy carbonated soils and intensive agriculture lands as well as in south-eastern Lithuania‘s rivers of more acidic soils; Hardly degradable organics factor – in northern and middle Lithuania‘s rivers of heavy-textured and fertile agricultural soils.

Abstract:

This dissertation describes two related studies on hydrogenation and hydrodesulfurization of heterocyclic S-containing compounds. Alkyl substituted thiophenes are promising candidates for hydrogen carriers as the dehydrogenation reactions are known to occur under mild conditions. Four types of catalysts including supported noble metals, bimetallic noble metals, transition metal phosphides and transition metal sulfides have been investigated for 2-methylthiophene (2MT) hydrogenation and ring opening. The major products were tetrahydro-2-methylthiophene (TH2MT), pentenes and pentane, with very little C5-thiols observed. The selectivity towards the desired product TH2MT follows the order: noble metals > bimetallics > phosphides > sulfides. The best hydrogenation catalyst was 2% Pt/Al2O3 which exhibited relatively high reactivity and selectivity towards TH2MT at moderate temperatures. Temperature-programmed desorption (TPD) of hydrogen indicated that the H2 desorption amount was inversely related to the rate of TH2MT formation. Temperature programmed reaction (TPR) experiments revealed that pentanethiol became the major product, especially with HDS catalysts like CoMoS/Al2O3 and WP/SiO2, which indicates that poisoned or modified conventional HDS catalysts would be good candidates for further 2MT hydrogenation studies. The role of tetrahedral Ni(1) sites and square pyramidal Ni(2) sites in Ni2P hydrotreating catalysts was studied by substitution of Ni with Fe. The Fe component was deemed as a good probe because Ni2P and Fe2P adopt the same hexagonal crystal structure, yet Fe2P is completely inactive for hydrodesulfurization (HDS). For this purpose a series of NiFeP/SiO2 catalysts were prepared with different Ni:Fe molar ratios (1:0, 3:1, 1:1, 1:3, and 0:1) and investigated in the HDS of 4,6-dimethyldibenzothiophene at 300 and 340 oC. The uniformity of the NiFe series was demonstrated by x-ray diffraction analysis and by Fourier transform infrared (FTIR) spectroscopy of adsorbed CO. The position of substitution of Fe was determined by extended X-ray absorption fine structure (EXAFS) analysis. It was found that at 300 oC the HDS activity of the catalysts decreased with increasing Fe content and that this could be explained by the substitution of Fe at the more active Ni(2) sites. As temperature was raised to 340 oC, the activity of the Fe-containing samples increased, although not to the level of Ni2P, and this could be understood from a reconstruction of the NiFe phase to expose more Ni(2) sites. This was likely driven by the formation of surface Ni-S bonds, which could be observed by EXAFS in spent samples.

Abstract:

Ce travail de thèse étudie l’influence de la morphologie des feuillets de sulfure de molybdène sur la sélectivité des catalyseurs d’hydrotraitement. Les feuillets de phase active présentent en effet deux types de bords appelés « M-edge » et « S-edge » susceptibles de conduire à des réactivités différentes. Le changement de la morphologie 2D des feuillets pourrait modifier les proportions de bords M et S exposés et ainsi les propriétés catalytiques des catalyseurs sulfures. Pour cela, des catalyseurs non promus (Mo) et promus (CoMo), supportés sur alumine ont été préparés par imprégnation à sec puis sulfurés dans des conditions variées (gaz et température). Des tests catalytiques en hydrodésulfuration (HDS) sélective des essences de FCC (sélectivité HDS/HYD) ont ensuite permis d’évaluer l’impact de la morphologie en s’appuyant sur des modèles géométriques construits à partir de calculs DFT et de caractérisations expérimentales (TEM, IR (CO), TPR, XPS). Les résultats obtenus pour les catalyseurs de type Mo semblent ainsi confirmer l’influence de la morphologie 2D sur la sélectivité HDS/HYD, le bord M paraissant être le plus sélectif pour les catalyseurs non promus. Ils mettent également en évidence l’importance de la réductibilité plus ou moins marquée des bords sur les propriétés catalytiques, notamment sur le bord M. Le changement des conditions de sulfuration semble donc affecter la morphologie des particules mais également les propriétés chimiques propres à chaque bord. En ce qui concerne les catalyseurs promus, la variation des conditions de sulfuration semble agir essentiellement au niveau de la répartition du promoteur entre les bords M et S. Cependant, les interactions avec le support paraissent constituer un frein aux effets de promotion. Dans ce contexte, les sulfurations à haute température sous H2S pur permettent d’obtenir des gains significatifs en activité et sélectivité. Ces résultats semblent dus à de faibles interactions avec le support et une décoration privilégiée du bord S qui pourrait favoriser la réaction d’HDS et limiter la réaction d’HYD. Au final, les interprétations effectuées en terme de morphologie 2D tendent à confirmer que ce paramètre peut constituer un axe de développement intéressant pour les catalyseurs d’hydrotraitement. L'optimisation des conditions de sulfuration permettraient bien de faire varier la morphologie et le taux de décoration du promoteur des catalyseurs, améliorant ainsi significativement l'activité et la sélectivité
This thesis examines the influence of the morphology of particles of molybdenum sulfide on selectivity of hydrotreating catalysts. Nanoparticles of active phase present two types of edges called “M-edge” and “S-edge” which may lead to different reactivities. The change in morphology of the 2D sheets could change the proportions of M and S edges exposed and thus the catalytic properties of sulfide catalysts. For this, non-promoted (Mo) and promoted (CoMo) catalysts, supported on alumina were prepared by dry impregnation and sulfide in various conditions (gas and temperature). Catalytic tests in selective hydrodesulfurization (HDS) of FCC gasoline (selectivity HDS /HYD) were then used to assess the impact of the morphology based on geometrical models which were constructed with DFT calculations and experimental characterizations (TEM, IR (CO), TPR, XPS). The results for Mo catalysts seem to confirm the influence of the 2D morphology selectivity HDS / HYD, M-edge appearing to be the most selective for non-promoted catalysts. They also highlight the importance of the reducibility more or less pronounced of the edges on the catalytic properties, especially on the M-edge. The different conditions of sulfidation seem to affect the morphology of the particles but also the specific chemical properties at each edge. Regarding to the promoted catalysts, the different conditions of sulfidation appear to act primarily at the distribution of the promoter between the M and S edges. However, interactions with the carrier appear to constitute an obstacle to promoting effects. In this context, sulfidations at high temperature in pure H2S lead to obtain significant gains in activity and selectivity. These results appear to be due to weak interactions with the carrier and to the presence of the promoter on the S-edge which could promote the HDS reaction and limit the HYD reaction. Finally, the interpretations made in terms of 2D morphology tend to confirm that this parameter can be an interesting line of development for hydrotreating catalysts. Optimization of the sulfidation conditions could effectively allow to vary the morphology and the rate of decoration of promoted catalysts which significantly improve the activity and selectivity

Abstract:

When talking about how to present information in virtual reality, the possibilities are countless, but there are also many problems surrounding the spatial location of the information. This study aims to examine where and how the instructions in a vehicle training simulator should be presented in a future implementation of the interface in virtual reality. To find this out, a gameplay was created in which four different placements of the instructions were made. Three options were based on earlier studies made by Smith (2015) and Jose (2016) and the fourth was based on the existing information in the vehicle training simulator. These gameplays were presented as a movie to a number of interviewees and followed up by questions after each movie. The interviewees were asked to give the movies three ratings from 1-5, valuing how they perceived the presentation of the instructions. To get further opinions, comments was collected from the interviewees throughout each session. In this two ways, we got answers to which of the four options the interviewees thought was best. The study showed that there were two options that stood out among the others and both were based on the concept of a head-up display, also known as a HUD. One was represented in the bottom of the windshield and the other one in the top. The result of which one of them who were perceived as best is too close to say, although the study is considered to have reached its goal, which was to help the developers on their way to a decision that will eventually be implemented.

Abstract:

Volatility modelling is used predominantly in order to explain the volatility smile observed in the market. Stochastic volatility models are mainly used to capture the curvature of a volatility smile while local volatility models generally model the skew. Jackel and Kahl ¨ (2008) present a hyperbolic-local hyperbolic-stochastic volatility (Hyp-Hyp) model which aims to improve upon existing local and stochastic volatility models such as the stochastic alpha, beta, rho (SABR) and constant elasticity of variance (CEV) models. The advantageous features of the Hyp-Hyp model are corroborated by implementing the model. Jackel and Kahl ¨ (2008) investigate the accuracy of a scaled analytical approximation for implied volatility, based on approximations presented by Watanabe (1987) and Fouque et al. (2000), for the Hyp-Hyp model. They use the approximation to derive an expression for the delta of an option. This dissertation analyses the Hyp-Hyp model, as well as the approximation, by deriving expressions for other sensitivities and by investigating the effect of the Hyp-Hyp model parameters on the volatility smile. The accuracy of the analytical approximation for functional forms other than those defined by the Hyp-Hyp model is explored. A derivation of the approximation is undertaken, presenting corrections to the expressions introduced by Kahl (2007) and used by Jackel and Kahl ¨ (2008).

Abstract:

Uppsatsens syfte är att analysera hur hudvårdsmärken och hudvårdsanvändare konstruerar och upprätthåller föreställningar om perfekt hy och idealet om naturlig skönhet. Paradoxalt nog har detta ideal resulterat i en växande hudvårdstrend, en trend som får unga kvinnor att spendera tid, energi och pengar på ännu en aspekt av sitt yttre. Uppsatsen har en tolkande forskningsansats, och metoden består av både en kvantitativ innehållsanalys samt en semiotisk bildanalys. Målet med studien var att analysera vilken typ av hy som representeras på Instagram. Resultatet visar att den mest representerade typen av hy är ljus, ung, jämn och frisk, samt tillhör en kvinna. Hudvårdsmärkena visade på binära framställningar av hy. Detta mönster fanns även hos hudvårdsanvändarna. Den största skillnaden mellan märkena och användarna var representationen av ojämn eller sjuk hy. Användarna har en större tendens att dela med sig av material som visar icke-ideal hy.

Abstract:

SammanfattningKängurumetoden (KMC) innebär att bära nyfödda barn direkt mot en människas hud. Detta påverkar barnet på olika sätt och mycket finns dokumenterat kring detta. Syftet med denna studie var att beskriva föräldrars upplevelser med att vårda sitt nyfödda barn med kängurumetod. För att besvara syftet utfördes en systematisk litteraturstudie. Resultatet från tio artiklar sammanfattades i fem olika kategorier. Kategorierna var: Underlättad anknytning, Naturlig kroppslig närhet, Trygghet i rollen som förälder, Rädsla, obehag och otillfredsställelse, och Psykiskt välbefinnande. Föräldrar som använt KMC upplevde bland annat välbefinnande, förbättrad anknytning och trygghet som förälder. Efter genomgång av artiklarna kunde författarna konstatera att det är viktigt att sjuksköterskans omvårdnad omfattar hela familjen för att optimera deras stöd för varandra. Det är också viktigt med information för att göra föräldrarna trygga i sin föräldraroll.

Abstract:

Human β-defensins (hBDs) are a family of cationic peptides able to directly kill a wide range of microorganisms including bacteria, fungi and viruses. In addition to their antimicrobial activities, defensins also contribute to the modulation of both the host innate and adaptive immunity. In this project, we demonstrate that the αCD3/28 co-stimulation of human CD4+ T cells in the presence of 10μg/ml hBD-2 or hBD-3 together causes an up-regulation in numbers of CD4+CD69+CD25+ and CD4+CD69-CD25+ T cell subsets, indicating that the treatment of hBD-2 and 3 enhances CD4+ T cell activation. Consistent with this finding, proliferation assay using CFSE suggests that hBD-2 and hBD-3 treatment in vitro induces the proliferation of CD4+ T cells following by 96hrs culture. Analysis of expression of the regulatory T cells (Tregs) specific marker, FoxP3, reveals a shift in the CD4+CD127-CD25+ Treg subset at 18hrs. However, at the later time point, we found that the percentage of FoxP3+cells decreased in the CD4+CD127-CD25+ Treg population, whereas the presence of the FoxP3+CTLA-4+ Treg subset increased. These data indicate that Treg suppressive function may be potentially defective following the co-incubation of purified T cells with either hBD-2 or hBD-3 for 42hrs in vitro due to the apparent loss of FoxP3 expression. We further characterise the role of hBD-2 and hBD-3 in driving human CD4+ T cells polarisation. Our in vitro data suggests that treatment with hBD-2 and hBD-3 can not only induces effector T cell (Teff) differentiation into RORγt+T-bet+ (Th17/Th1) cells, but can also trigger the differentiation of Treg expressing RORγt and T-bet rather than the master controller of Treg function, FoxP3. This apparent plasticity of T cell phenotype allows them to convert from Treg to Th1/17-like effector T cell phenotype following 18hrs in culture. By 42hrs in culture, treatment with hBD-2 and hBD-3 induced both Teff cell and Treg cell differentiation towards the Th17-like phenotype. Compared with the treatment with hBD-2, treatment with hBD-3 induced a more pronounced effect to increase levels of RORγt in CD4+ T cells. This elevated expression may, in turn, be responsible for the induction of higher IL-17A secretion. Consistent with this idea, it was found that treatment with hBD-3 but not hBD-2 was capable of inducing the higher level of secretion of IL-17A. Additionally, treatment with hBD-3 induced an increased expression of IL-6, which is capable of driving the differentiation of naïve T cells towards IL-17-producing Th17 cells. Functionally, using the Treg suppression assay, the data suggested that hBD-2 may dampen down Treg cell ability to induce suppression of Teff cell activity. Interestingly, co-culture with hBD-2 would also appear to increase Teff cell resistance to Treg immunoregulation in vitro. Further investigation using microarray gene analysis revealed chemokine C-C motif ligand 1 (CCL1) as potential genes responding to hBD-2 treatment. The blockade of CCL1 has been reported to inhibit Treg suppressive function. Thus, this study explored the function of these antimicrobial candidates in regulating CD4+ T cell plasticity which could result in hBD-2 and hBD-3 being able to regulate its own production, but also may regulate Treg and Teff cell development and function, thus strengthening the link between innate and adaptive immunity.

Abstract:

Studier har visat att hud-mot-hud har flera positiva effekter för modern och det nyfödda barnet. Trots detta upplever barnmorskor hinder för kontinuerlig hud-mot-hud under föräldraparens BB-vistelse. Syftet med arbetet var att beskriva barnmorskors tankar kring hinder och möjligheter för kontinuerlig hud-mot-hud på barnbördshus (BB). Forskning finns om hud-mot-hud men inga specifika studier om barnmorskors tankar kring vilka hinder och möjligheter som finns för kontinuerlig hud-mot-hud under BB-vistelsen. En intervjustudie utfördes och materialet bearbetades med kvalitativ innehållsanalys för att lyfta fram de viktigaste aspekterna. Resultatet som framkom belyser barnmorskors tankar om hinder och möjligheter vid implementering av kontinuerlig hud-mot-hud under barnets första dygn på BB. Resultatet av studien visade att barnmorskorna största hinder var brist på riktlinjer, förekomsten av barnsängar, bristande föräldrainformation, platsbrist, samt föräldrarnas kulturella bakgrund och personalens attityder. De möjligheter som lyftes fram var enkelrum, bärhjälpmedel såsom tubtopp eller bärsjal, samt att utbilda föräldrarna under graviditeten. Vårdhandlingen införlivas lättast om de blivande föräldrar deltar i förberedande föräldrakurser under graviditeten, samt att personalen är välutbildade och uppmuntrar till hud-mot-hud.
Studies have shown that skin-to-skin care has several positive effects for both the mother and the newborn. Despite this, midwifes experience that it can be difficult to get parents to implement the skin-to-skin care continuously during its stay the maternity ward. The aim of the thesis is to describe midwives’ thoughts on the obstacles and opportunities for continuous skin-to-skin care at the maternity ward. There are studies on skin-to-skin care but no specific studies regarding midwives’ thoughts on the obstacles and opportunities for continuous skin-to-skin care during maternity stay. An interview study was conducted, and the material was processed using qualitative content analysis to highlight the main points. The result highlighted midwives’ thoughts on the obstacles and opportunities in the implementation of continuous skin-to-skin contact during the child's first days in the maternity ward. The results of the study showed that midwives biggest obstacles are the hospital baby beds, as well as lack of guidelines, parental information, private rooms, and the parents' cultural background and the staff attitudes. The opportunities that arouse were private rooms, aids such as tube tops or slings, and prenatal parental training during pregnancy. Skin-to-skin care can most easily be implemented when parents participate in preparatory parenting training, and when the staff is well trained and encourage implementing skin-to-skin care.

Abstract:

Trots att evidens finns att vård av det nyfödda barnet hud mot hud hos sin mor främjar anknytning och amning separeras barnet från sin mor på grund av förlossningsavdelningens arbetssätt. Vid en födsel uppstår det ofta en bristning i underlivet varav de flesta kan sys på förlossningsrummet. Om den nyblivna modern är i behov av spinalanestesi för att sy bristningen flyttas modern till operationsavdelningen och en separation uppstår. Syftet med förbättringsarbetet var att införa ett nytt arbetssätt för att främja vård hud mot hud när en bristning i underlivet behöver sys i spinalanestesi. Efter införandet av det nya arbetssättet i oktober 2019 har 20 barn vårdas hud mot hud då bristningen sytts i spinalanestesi på förlossningsrummet. I de uppföljande samtalen med de nyblivna föräldrarna och personalen var övervägande mycket nöjda med det nya arbetssättet. Arbetssättet har även bidragit till att användningen av klinikens resurser reducerats. En kvalitativ intervjustudie utfördes med syftet att studera faktorer som motiverar personalen vid införandet av det nya arbetssättet. I studien framkom tre motiverande faktorer; att göra det bästa för mor och barn, att få feedback och stöd i genomförande av det nya arbetssättet samt känslan att vara delaktig i processen.

Full text

Abstract:

Syftet med det här arbetet har varit att dels fördjupa mina egna kunskaper om beröringens betydelse för människan och människans utveckling och dels att söka kunskap om vilka reaktioner som sker i kroppen vid positiv beröring. Kunskaperna kommer sedan att ligga till grund för mötet med mina elever i framtiden. Resultaten bygger på läst litteratur inom området och på en intervju med en person som har stor erfarenhet av beröring och massage i skolan.

Vi kan inte överleva om ingen rör oss, ingen ser oss, ingen bryr sig om oss. Beröring är inte bara vägen till känslomässig kontakt, den taktila kommunikationen är också relaterad till inlärning. Beröring är att kommunicera. Beröringssinnet, som är en del av känselsinnet, är det första sinnet som utvecklas hos det lilla barnet och ofta det sista sinnet som kvarstår vid ålderdomen. Genom att beröra varandra på ett positivt sätt skapas vänskapsband och trygghet. För att människan ska kunna utveckla koncentration, organisationsförmåga och teoretisk inlärning måste våra sinnen vara integrerade och kunna samordnas i hjärnan. Denna integrering sker i fyra flytande nivåer, där beröringen är en viktig delkomponent. Forskning inom området visar på att beröring minskar mängden stresshormoner i blodet. Vid forskning på djur har man kunnat uppmäta höjda halter av lugn- och rohormonet oxytocin i blodet efter lätt massage.

På flera skolor i landet har man infört en typ av beröring som kallas kompismassage. Det har bland annat resulterat i ett lugnare och trevligare klassrumsklimat, bättre kamratrelationer och mindre mobbning. Genom en ökad medvetenhet om beröringens betydelse kan vi som arbetar i skolan bli mer uppmärksammade på hur vi kan använda beröring i ett utvecklande syfte.

Full text

Abstract:

This thesis argues that H.D.'s creativity originates in a flight from reality. Hilda Doolittle's adoption of her initials is interpreted as a sign of the writer's rejection of any identity located in the shared reality of the historical and the quotidian. From childhood her personality presented itself to her as a duality; detaching herself from the merely visible and material world, H. D. created an intense inner life which asserted itself in the dimension of artistic realization. It is argued that paradoxically the unevenness and discontinuity that characterize H.D.'s work derive from the same roots as her artistic originality and power: in her "split dual personality" which posited reality in the disembodied self. H.D. discovered in ancient Greece a metaphor and a direction for her own inner world. However her Imagist poems are not imitative but genuinely original: H.D. invented a new reality which she projected as a world devoid of all traces of human presence. H.D.'s subsequent shift of interest towards autobiographical prose is interpreted as a response to the threatened disintegration of her identity after World War I. The formlessness and repetition of much of H.D.'s prose is thus attributed to the exacerbation of the writer’s dichotomy of being. However, in some of her prose works H.D. succeeded in transfiguring the autobiographical material through the reinvention of reality in the image of her own subjectivity. Seeking new forms for her projection of the self, H.D. turned increasingly towards the occult which she understood as the science of the invisible dimension. She conflated with the occult her discoveries of the cinema as self-projection, and psychoanalysis as an instrument of knowledge of the inner being. It is argued that these interests exacerbated the solipsism inherent in H.D.'s rejection of external reality. With the exception of the war Trilogy, H.D.'s work becomes locked in private meanings which render it increasingly inaccessible to the reader. It is argued that after her mental breakdown in 1946, H.D. never recovered her vitality and originality as an artist. The space that this thesis devotes to the life of H.D. does not intend to justify her work by her life, but to signify that the literary message cannot be isolated from the circumstances in which the process of creation takes place. Thus H.D.'s flight from reality is not judged from an existential point of view as a diminution of being, since it is out of her "split dual personality" that H.D. emerges as a genuinely creative and original artist.

Abstract:

My degree project consists of The Haven, a single-channel video (19.25 min) and So nothing had really changed, a prose text which is also my master essay. They are two stand-alone works, but with a strong connection in that the text refers to the film. The film tells the story of an undefined we and their everyday existence. It takes place in the communal laundry house - or tvättstugan, typical to Swedish housing complexes - where they spend time to meet their physical needs, as well as to live in an illusion for a couple of hours and be part of a bigger we. The text tells the story of a woman enrolled in an art university, working on her projects while trying to adapt to life as an art student, when a shattering incident in her private life starts a process dealing with loss, shame, feelings of guilt and questions about identity. A new film script is slowly coming to life, but she is struggling within herself; not wanting to do it, and at the same time, not being able to stop it.

Abstract:

Tio procent av alla barn som föds i Sverige vårdas på neonatalavdelning. Där arbetar barnsjuksköterskor med särskild kompetens inom barn- och barnsjukvård med en viktig roll att stärka barns rätt till hälsa och föräldrarnas delaktighet i vården. Hud-mot-hud är en omvårdnadsmetod som har visat sig ge många fördelar för barnen. Samtidigt har utmaningar identifierats kring hur hud-mot-hud kan genomföras på bästa sätt och att barnsjuksköterskors uppfattningar och attityder kan påverka resultatet. Syftet med studien var att beskriva barnsjuksköterskors uppfattningar om och attityder till att vårda hud-mot-hud på neonatalavdelning. Sex intervjuer med sjuksköterskor har genomförts via digitala videoverktyg. Resultatet visade att barnsjuksköterskor är positivt inställda till att vårda hud-mot hud. De anser att det är det viktigaste föräldrarna kan göra för sitt barn och ser det som sitt ansvar att göra dem delaktiga i vården och stötta dem så att anknytningen främjas. Diskussion har förts utifrån hur det är att vårda de mycket för tidigt födda och svårast sjuka barnen, vad hud-mot-hud betyder för anknytningen och familjecentrerad vård. Slutsatsen blir att barnsjuksköterskor med sin unika kompetens kan stärka föräldrarna i hud-mot-hud-vården så att barnens hälsa främjas.

Abstract:

Sammanfattning För att ge förutsättningar till optimal tillväxt och utveckling vårdas idag, tillsammans med andra behandlingar, prematura barnen på neonatalavdelningar hud mot hud. Vård hud mot hud av det prematura barnet sker oftast på mammas eller pappas bröst och forskning visar att detta är en gynnsam miljö för barnets utveckling och hälsa. Det har också en positiv inverkan på föräldrarnas anknytnings process. En otrygg anknytning kan leda till ohälsa längre fram i livet och det är därför viktigt ur ett folkhälsoperspektiv att det finns forskning som visar hur personalen ska gå till väga för att ge stöd och hjälp till föräldrar att vårda sitt barn hud mot hud. Syftet med denna undersökning var att ta reda personalens uppfattning och erfarenheter av att vårda barn hud mot hud. För att undersöka detta genomfördes sju semistrukturerade intervjuer med barnsjuksköterskor och barnsköterskor på en neonatalavdelning på ett sjukhus i mellan Sverige. Materialet som intervjuerna gav analyserades genom kvalitativ innehållsanalys. I resultatet framkom tre kategorier: personalens syn på sin roll, barnperspektiv och föräldraperspektiv. Kategorierna resulterade i temat ”motstridiga känslor hos personalen”. Detta framkom genom att personalen i sin roll och med sin kunskap om hud mot hud även behöver förhålla sig till barnets behov och barnets rätt till bästa vård samt föräldrarnas behov och svårigheter. Sammanfattningsvis framkom att kunskap, kunskapsöverförande samt att ge föräldrar praktisk hjälp är viktiga för att öka antal timmar barnet vårdas hud mot hud.

Abstract:

Bakgrund: Hud mot hudkontakt är nödvändigt för att främja närhet och anknytning hos det prematurt födda barnet samt förstärker föräldrarollen.Syfte: Syftet med studien var att belysa män och kvinnors, dvs föräldrar till för tidigt födda barn och deras upplevelser av att använda metoden hud mot hud. Metod: Kvalitativ ansats där data samlades in genom intervjuer och analyserades med hjälp av en tematisk innehållsanalys. I studien ingick sammanlagt tolv informanter från södra Sverige vilka intervjuades under barnets vårdtid eller kort därefter. Resultat: Huvudresultatet mynnade i fyra kategorier ”Motstridiga känslor”, ”Viktigt för barnets utveckling”, ”Viktigt för anknytning och närhet” och ”Betydelsen av personalens kompetens och stöd”. Vidare ledde dessa till sex underkategorier ”Tidskrävande”, ”Barnfokuserad”, ”Förstärkte föräldrarollen”, ”Effekter av hud mot hud på föräldrarna”, ”Att försöka njuta och leva i nuet” och ”Betydelsen av miljön runt omkring”. Konklusion: Både kvinnor och män upplevde att dessa blivit föräldrar på riktigt när de fick utöva hud mot hudkontakt. Metoden hade även positiva effekter på föräldrarna. Vidare framkom att information var av stor betydelse och specialistsjuksköterskan och dess team bör eftersträva att ge upprepad information.
Background: Skin-to-skin contact is necessary to promote closeness and attachment to the prematurely born baby and to strengthen the parenting role. Aim: The purpose of the study was to highlight women and men ́s, namely parents to early-born children and their experiences of using the skin-to-skin method. Method: Qualitative approach where data was collected by interviews and analysed by a thematic content analysis. The study included a total of twelve informants from south of Sweden, who were interviewed during their child’s care period or shortly after. Result: The main result led to the four following categories “Conflicting feelings”, “The importance of skin-to- skin for the child’s development”, “Important for attachment and closeness” and “The importance of competent staff and their support”. Furthermore, these led to six subcategories “Time-consuming”, “Child-focused”, “Strengthening the parent role”, “The impact skin-to-skin have on the parents”, “Trying to enjoy and live in the present” and “The importance of the environment”. Conclusion: Both women and men felt that them had become parents for real when they were allowed to use skin-to-skin contact. The method also had positive effects on the parents. Furthermore, it emerged that information was of great importance and the specialist nurse and team should strive to providing repeated information.

Abstract:

Utredning av vuxna med förmodad neuropsykiatrisk funktions-nedsättning har blivit allmänt förekommande först på 2000-talet. Trots att utredningen är omfattande finns endast lite forskning kring hur utredningen påverkar patienten. Effekter, mestadels symtomlindrande, har påvisats vid andra utredningsformer men mycket skiljer dessa utredningar från de neuropsykiatriska. Huvudsyftet med denna studie är att undersöka symtomförändringar och hälsofrämjande effekter för patienten vid neuropsykiatrisk utredning. Single case-design har använts, deltagarna var sex patienter remitterade för neuropsykiatrisk utredning i två olika landsting, och har mätts gällande variablerna ångest, depression och känsla av sammanhang. Resultaten pekade mot symtomlindring och/eller ökad känsla av sammanhang. Detta talar för att tätare samarbete mellan utredande och behandlande enheter bör eftersträvas, och att man genom en medveten strävan skulle kunna öka behandlingseffekterna.

Assessment of adults with neuropsychiatric impairments have become more common in the beginning of the 21st century. Due to the extensive nature of the neuropsychiatric assessment procedure it is likely that the assessment will have an influence on the patients presenting problem. Despite this the authors have found only a few research studies on the subject. Some previous studies have shown other types assessments to pose an influence on symptoms. The main purpose of the present study is to investigate whether neuropsychiatric assessment poses an influence on symptoms and/or salutogenic factors. The present study uses a single case design with six patients from two separate neuropsychiatric units. The participants have been measured using the Hospital Anxiety and Depression scale and the Sense of Coherence Questionnaire. The results indicate that symptoms are alleviated and/or Sense of Coherence is promoted due to the assessment. The implications of these results suggest that closer co-operation between assessment and treatment centres is warranted and is likely to be beneficial to the patient in the sense of more useful assessments and more efficient treatments.

Titel: Varför hyr företag in extern personal?

Bakgrund: Faktorer till varför företag hyr in extern personal från bemanningsföretag har diskuterats livligt under lågkonjunkturen som varit. Det råder delade meningar om huruvida företag säger upp personal för att istället kunna hyra dem från bemanningsföretag.

Syfte: Att klargöra varför företag använder sig av bemanningsföretag och i vilka situationer.Avgränsningar: Studien kommer att beröra företag som är baserade i Växjö. Tre branscher kommer att studeras, varav två företag i varje bransch. Teorin berör arbetsrätten samt organisationsteori.

Metod: En kvalitativ undersökning i form av semi- strukturerade intervjuer har genomförts på sex personer i tre olika branscher (media & PR, IT samt industri/produktion). Personerna som intervjuats är: Anne Bergstrand (SVT), Helen Gröön (Atea Logistics), Karin Korpe (Fortnox), Lena Björkqvist (VEAB), Mikael Berg (GoodRace) och Åke Blomqvist (Södra Timber). Materialet i empirin har sedan analyserats med hjälp av fördjupade teoretiska studier.

Resultat och slutsatser: De främsta faktorerna till varför företag hyr in extern personal till deras verksamhet är att de köper sig en viss ansvarsfrihet. Denna ansvarsfrihet gör att verksamheterna kan agera mer flexibelt och agera bättre och snabbare på omvärldstryck.

Förslag till fortsatt forskning: en fördjupad undersökning i företags förtroende till bemanningsföretagen och tillhörande personal.

Denna undersökning genomfördes genom åtta kvalitativa intervjuer, där deltagarna fick testa två olika versioner av ett spel, med olika animationer. Deltagarna filmades för att kunna observeras i efterhand. Data visar att spelare påverkas av tidigare erfarenheter och av spelkaraktärens fackla. Detta påverkade vilka animationer deltagarna uppfattade som realistiska. Data visade också på att Freemans m.fl. teori inte gick att applicera eftersom deltagarens spelvana tog över den kognitiva responsen. Vidare forskning kan göras på Freemans m.fl. metod för att se hur spelvanan hindrades, och även se hur spelare påverkas av ett annat objekt än en fackla.

Abstract:

I den här rapporten har vi undersökt hur man genomför en re-design av logotyp och hur man kan förmedla kärnvärden genom grafiskt material. Vi fick i uppdrag ifrån Hollies Reklambyrå att re-designa Hud & Hälsocenters ursprungliga logotyp samt grafiskt material. Det är inte ovanligt att företag inte förstår hur viktigt det är att ens grafiska profil är uppdaterad och förmedlar det man står för. Eftersom det kan kosta en del att byta ut den befintliga grafiska profilen så är många företag tveksamma inför det. Dock kan man tjäna igen de pengarna genom en re-design då man på ett bättre sätt lyckas förmedla sitt budskap och nå nya kunder. Syftet med arbetet är att förstärka Hud och Hälsocenters identitet som fokuserar på välmående både i det yttre och det inre. Målgruppen ska känna sig trygg samtidigt som de ska uppleva ett varmt omfamnande. Vi bröt ned syftet i följande frågeställningar: Hur kan man genomföra en re-design av en logotyp? Hur kan man förmedla Hud och Hälsocenters kärnvärden i ett nytt grafiskt material? De metoder vi använde oss av för att besvara frågeställningarna var att genomföra intervjuer med Hollies Reklambyrå och Hud & Hälsocenter. Sedan genomförde vi en litteraturstudie, konkurrensanalys och designprocess. Resultatet från designprocessen fick vi feedback på från tre referenspersoner. I genomförandet av våra metoder och med en gedigen teoretisk bakgrund kan vi i resultatet förmedla Hud & Hälsocenters kärnvärden i ett nytt grafiskt material. Vi har tagit fram en ny logotyp, visitkort, brevpapper samt design på hemsida. De slutsatser vi har kommit fram till är att det inte finns något specifikt tillvägagångssätt i en re-design av logotyp då det kan skilja sig mellan olika uppdrag och designers. Huvudsaken är att de förändringar som görs inte talar emot det budskap man vill förmedla utan istället förstärker kärnvärdena. Det krävs flera delar i det grafiska materialet för att förmedla kärnvärdena till målgruppen. Endast en komponent kan inte spegla alla på egen hand.
In this report, we have examined how to make a re-design of a logotype and how to express the words of value of the graphic material. We got an assignment from Hollies Reklambyrå to re-design Hud & Hälsocenter’s original logotype and graphic material. It is not unusual that companies do not understand how important it is that one's visual identity is updated and expresses what you stand for. Because it can cost a lot to replace the existing graphic identity many companies hesitate to do so. However, one can earn back the money through a re- design because then you express your message in a better way and can reach new customers. The purpose of this work is to enhance Hud & Hälsocenter’s identity that focuses on well-being in both on the inside and outside. The target group should feel safe and experience a warm embrace. We broke down the purpose of the following questions: How to conduct a re-design of a logo? How to express Hud & Hälsocenter’s words of value in a new graphic material? The methods we used to answer the questions were interviews with the Hollies Reklambyrå and Hud & Hälsocenter. Then we conducted a literature review, analysis of competitors and a design process. During the design process, we received feedback from three referees. The implementation of our methods and with a solid theoretical background, we could express Hud & Hälsocenter’s words of value in the Result, in a new graphic material. We have developed a new logotype, business card, letterhead and design of a website. The conclusions we have reached is that there is no specific procedure in a re- design of the logotype as it can differ between different assignments and designers. The main thing is that the changes made do not contradict the message you want to convey, but instead reinforces the Hud & Hälsocenter’s words of value. It requires several components in the graphical material to convey the words of value to the target group. Only one component may not reflect all on its own.

Abstract:

Heads Up Display (HUD) technologies are being developed to assist drivers and reduce safety hazards. The current study used the Lane Change Task (LCT) and a Peripheral Detection Task (PDT) divided into high and low workload tracks to assess effects of employing a HUD to alert drivers to moving objects in their periphery that are possible hazards. The intent of the current study was to determine whether visual warnings displayed in either color, flashing, or color and flashing formats, would improve detection of moving stimuli without adversely impacting driving ability. Results indicated that the PDT had no significant effect on LCT performance. However, significant main effects of warning format and workload on reaction times, false alarm rates, and sensitivity were obtained. Performance on the PDT task was best when the warnings were non-flashing and yellow, especially in the low workload condition. Explanations of performance on both tasks are discussed.

Abstract:

A lo largo de su carrera, la poetisa estadounidense Hilda Doolittle (1886-1961) se comprometió con la mitología clásica. A pesar de que produjo una gran cantidad de traducciones de la tragedia griega, muy pocas investigaciones se han desarrollado sobre esta parte de su trabajo. Con el fin de identificar las influencias y las relaciones de poder que confluyeron en las traducciones de H.D. y que dieron forma a su actividad como traductora, esta tesis no solo analiza las traducciones que hizo durante los primeros años de su carrera (1913-1920), sino que también estudia el contexto en el cual se produjeron dichas traducciones. La principal motivación que impulsa este estudio es la de indagar sobre el trato que H.D. dio al género en sus traducciones y sobre la medida en que los asuntos de género fueron relevantes en su papel como traductora.
Throughout her career, the American poet H.D. (1886-1961) engaged with classical myth. Despite the numerous translations from Greek tragedy that H.D. produced, very little research has been carried out into this area of the poet’s work. In order to identify the influences and power relations that fed into H.D.’s translations and shaped her activity as translator, this thesis analyses not only the translations that H.D. produced during the early stages of her career (1913-1920), but also the contexts in which these translations were rendered. The driving force behind this study is the desire to interrogate H.D.’s treatment of gender in her translations and the extent to which questions of gender were relevant to her role as translator.

Full text

Abstract:

The work in this thesis aims to investigate the ductility of s-HD (solid hydrogenation disproportionation) processed book mould cast NdFeB material in order to develop a novel processing route for producing fully dense magnetic material with a high energy product. A major drawback of NdFeB–based alloys is that they are extremely brittle. Therefore, to produce a fully dense magnet these alloys must be broken down into a powder and hot pressed or sintered followed by cutting and grinding to the desired shape and precise dimensions. This process is time consuming, energy intensive and produces a significant amount of waste which is not readily recyclable. This thesis reports a potentially new application of hydrogen as a promising high temperature processing tool in which the normally brittle Nd\(_2\)Fe\(_1\)\(_4\)B based intermetallic absorbs and reacts with hydrogen, converting it into a ductile, disproportionated condition, which can be subsequently compressed at room temperature. It can then be restored to its original state by removal of the hydrogen under partial vacuum at elevated temperatures. By maintaining a solid form throughout, almost zero waste material is produced and the deformed material exhibits a high coercivity and a useful degree of anisotropy.
