Jonsson, Lisa, i Anna Johansson. "Examensprojekt bar-Nstol". Thesis, Halmstad University, School of Business and Engineering (SET), 2008. http://urn.kb.se/resolve?urn=urn:nbn:se:hh:diva-1628.
Pełny tekst źródłaProjektet inleddes med en omfattande marknadsundersökning där syftet var att ta reda på vad primär- och sekundäranvändare av höga barnstolar har för åsikter om dessa och samtidigt undersöka det befintliga utbudet av höga barnstolar. På den undersökta marknaden hittades ingen barnstol som var ergonomisk för både barnet och föräldrarna. Det fanns inte heller någon som riktade sig till kunder med behov av en stol till barbordshöjd eller köksö. Då svenska kök i allt större utsträckning har antingen barbord eller köksö, upptäcktes här ett behov.
Ett skelett som växer är extra känsligt för snedbelastningar. Dessutom är kroppen inte gjord för att sitta i en traditionell nittiogradig sittställning. Alarmerande siffror på antalet ungdomar med ryggproblem gjorde det därför till ett självklart val att utveckla en stol som skulle vara ergonomisk för både barnet och föräldrarna. Projektgruppen arbetade fram tre koncept, för att senare besluta sig för att jobba vidare med ett sadelkoncept.
Med Svan AB, tillverkare av barnmöbler, som en extern mentor har projektet bedrivits i egen regi. För att komma fram till ett bra resultat har projektgruppen använt sig av en rad olika metoder. Bland annat så har en fokusgrupp varit engagerad under hela utvecklingsprocessen.
Projektgruppen har tagit fram tre modeller i naturlig storlek. Vid tillverkning av den första modellen så halverades måtten på en sadelsits för vuxna. Därefter har en mängd förändringar gjorts, mycket tack vare de användartester som utförts på barn både från Grottans föskola och BVC Nyhem. Sitsen tillverkades till slut i plåt och testades igen på olika barn från sex månader till sju år. Projektgruppen har hela tiden anpassat former och lösningar efter de mycket hårda standarderna som finns för höga barnstolar. Efter en rekommendation från Kjell Hagström som är VD på Svan AB så har projektgruppen följt både EU-standarderna och USA-standarderna. Den tredje modellen testades på många barn innan den slutgiltiga prototypen tillverkades.
Resultatet blev en barnstol med sadelsits som med hjälp av ett ben med gasfjäder går att höja upp till barbordshöjd. Sitsen är tillverkad i plåt som sedan har klätts med vaddering och konstläder. Bygel och ryggstöd är tillverkade i böjträ som betsats i en nyans som kallas för ”espresso”. Även fotstödet är tillverkat i trä som sedan har betsats. Bygel och ryggstöd går att justera i djupled medan fotstödet går att justera i höjdled.
Projektgruppen är mycket nöjd över resultatet, som efter ett slutgiltigt användartest bevisligen uppfyller både syftet och målet.

Pełny tekst źródłaContrary to some expectations, the study lauds the plurality of cultures confronted with the growing obsession of an integral levelling of cultural identities. Hence, far from drawing up whatever list of philosophies among the nso' of yore and of today, i have tackled some of the problems arising from that obsession. Apart from the two introductory chapters, where the essential problem is carved out, and the conclusion, the whole work presents two phases, one of which deals with the historical context of colonial and neocolonial philosophical practices with which the operative and creative aspirations of cultural communities such as that of the nso' of cameroon are wrestling; and the other offers a simultaneous cultural, historical and spatial outlook of the nso' country. Consequently, if the first phase enabled us to exhaust every sketch of the distinctions between the concepts of culture and its diverse forms of materialization such as language, race, religion and political bodies, the second phase attempts to present some perspectives which are functionally indigenous to the nso' culture, while unravelling the underlying conceptual elements from a vast corpus of taped, translated texts which we translate into french. Thus, the study covers the whole range of our fieldwork so as to enable our readers to make a better evaluation of the functioning of orally expressed philosophies. An interdisciplinary research, it's the dawn of the oral sciences

Pełny tekst źródłaDue to demographic, social, environmental and security reasons, the Nso' dynasty was forced to transfer its political capital in about 1780. The reorganization of the army and social dynamism followed the move to the site. As from the middle of the 19th century, Nso' society developed into a formidable complexity. Various aspects : political, economic, social, judiciary reached a sort of perfection. At the same time, a strong political ideology developed. In economy the kingdom is a raw material belt with the production of iron, kola ivory, tobacco, honey and some cloth. Commerce also developed between this raw material zone and consumer Nigerian cities. Colonization stopped this political experience in 1906, but the German and British colonial systems permitted the Nso to preserve their culture

Pełny tekst źródłaEukaryotic gene expression is regulated by a number of factors. Transcription initiation can be modulated by the binding of protein factors to specific sequences of DNA in the promoter of a gene. In addition, non-sequence (epigenetic) factors- namely, chemical modification of DNA and histones, the proteins around which DNA organizes to form chromatin - are a method of regulating gene expression by altering the structure of the chromatin environment and recruiting proteins that bind to the modifications. Two of the most common epigenetic modifications are acetylation of lysine residues on histones and methylation at the 5-position of the DNA base cytosine (5-methylcytosine, 5mC) within cytosine-guanine dinucleotides. Histone acetylation status is modulated by histone acetyltransferases (HATs) and histone deacetylases (HDACs). DNA methylation is mediated by DNA methyltransferases (DNMTs); however, for some time, the mechanism of DNA demethylation was unclear. It was recently shown that the TET family of proteins was capable of oxidizing 5mC to 5-hydroxymethylcytosine (5hmC) and further on to 5-formylcytosine (5fC) and 5-carboxylcytosine (5caC) as part of a putative DNA demethylation pathway. Here, we have begun to study the largely uncharacterized protein KIAA1310/NSL3, which associates with MOF, a HAT, in the NSL complex, as well as TET2 and TET3. KIAA1310/NSL3 contains an a/β hydrolase fold domain, which we hypothesize to be important to its function in these epigenetic complexes. Little is known about its role in these complexes, although it has been shown to be involved in recruiting RNA polymerase II to the transcription start sites (TSSs) of genes regulated by the NSL complex. We aimed to investigate KIAA1310/NSL3's function in the context of the TET2 and TET3 complexes. [TRUNCATED]

As leishmanioses compreendem um conjunto de doenças causadas por protozoários do gênero Leishmania e transmitidas pela picada de fêmeas de insetos flebotomíneos. Apresentam diferentes formas de manifestações clínicas de acordo com a espécie envolvida, podendo apresentar sintomatologia mais severa correlacionada à infecção por cepas mais virulentas. Estudos indicam que L. braziliensis, principal agente da leishmaniose cutânea e mucocutânea no Brasil, possui uma diversidade intra-espécie e que diferentes cepas estão relacionadas a diferenças na virulência, podendo influenciar o desenvolvimento de diferentes formas clínicas. Foi observado que as cepas ET e NSL apresentam características polares quanto à virulência e infecciosidade em modelo murino. Além disso, foi observado que essas cepas diferem na hidrólise de nucleotídeos extracelulares e que a alta taxa de hidrólise de ATP se correlaciona com a cepa NSL, de maior virulência. O mesmo trabalho identificou a presença de SNPs não silenciosos na sequência da NTPDase2 de NSL, mas nenhuma correlação com a atividade de hidrólise de nucleotídeos, virulência e infectividade foi observada. Considerando papel das NTPDases de Leishmania na hidrólise de nucleotídeos extracelulares e na modulação da resposta imune do hospedeiro, o objetivo desse trabalho consistiu em investigar a relação desses polimorfismos com a atividade da enzima NTPDase2, visando compreender as diferenças de hidrólise de nucleotídeos e virulência previamente observados. Nesse trabalho, a região que codifica para o ectodomínio da enzima NTPDase2 das cepas ET e NSL foi isolado e clonado em vetor bacteriano e a sequência correspondente ao ectodomínio de ET/NSL-NTPDase2 foi clonada no vetor pET21b, expressa e purificada. Análises de polimorfismos nas sequências indicam que os clones ET apresentam apenas SNPs silenciosos nas posições 861 e 879. Diferentemente, alguns clones NSL apresentam sequência idêntica à de ET e outros possuem SNPs nas posições 213, 296, 377, 554 e 1126, mudando os aminoácidos nas posições 99, 126, 185 e 376. Avaliando a estrutura 3D das proteínas, foi observado que a maioria das mutações são externas à enzima e que a mutação T376A se localiza em uma região predita como importante para a ligação ao substrato. Juntos, esses resultados levantam questões importantes acerca da influência desses SNPs na estrutura e atividade da enzima, que podem nortear experimentos futuros, a fim de elucidar o papel de variantes genéticas para a enzima NTPDase2 nos fenômenos observados para essas duas cepas em L. braziliensis.
Leishmaniasis comprises a set of diseases caused by Leishmania protozoa and transmitted by the bite of females of phlebotomine insects. They present different clinical outcomes according to the species and may present more severe symptomatology correlated to infection by more virulent strains. Studies indicate that L. braziliensis, the main agent of cutaneous and mucocutaneous leishmaniasis in Brazil, has an intra-species diversity and different strains are related to differences in virulence, who affects the development of different clinical forms. It was observed that the ET and NSL strains have polar characteristics regarding virulence and infectivity in murine model. Furthermore, it was observed that these strains differ in hydrolysis of extracellular nucleotides and the high rate of hydrolysis of ATP correlates with the NSL, the higher virulence strain. The same work identified non-silent SNPs in NTPDase2 sequence, but no correlation with nucleotide hydrolysis activity, virulence and infectivity was observed. Considering the role of Leishmania NTPDases in hydrolysis of extracellular nucleotides and modulation of the host immune response, the aim of this work was to investigate the relationship of these polymorphisms with the activity of the enzyme NTPDase2, in order to understand the differences of nucleotide hydrolysis and virulence previously observed. In this work, the coding region corresponding to ectodomain NTPDase2 from ET and NSL strains was isolated and cloned into a bacterial vector and the sequence corresponding to the ET / NSL-NTPDase2 ectodomain expressed and purified. Analysis of polymorphisms in the sequences indicates that all ET clones present only silent SNPs at positions 861 and 879. In contrast, some NSL clones have a sequence identical to ET and others have SNPs at positions 213, 296, 377, 554 and 1126, changing amino acids at positions 99, 126, 185 and 376. The 3D structure of the proteins, show that most mutations are external to the enzyme and the T376A mutation is located in a predicted region as important for substrate binding. Together, these results raise important questions about the influence of these SNPs on the structure and activity of the enzyme that can guide future experiments in order to elucidate the role of genetic variants for the enzyme NTPDase2 in the phenomena observed for these two strains in L. braziliensis.

Pełny tekst źródłaThis thesis is concerned with the expansions of some algebraic structures and their fit in Shelah’s classification landscape. The first part deals with the expansion of a theory by a random –or generic– predicate for a substructure model of a reduct of the theory. We describe a setup allowing such an expansion to exist, which is suitable for several algebraic structures. In particular, we obtain the existence of additive generic subgroups of some theories of fields and multiplicative generic subgroups of algebraically closed fields in all characteristic. We also study the preservation of certain neostability notions, for instance, the NSOP 1 property is preserved but the simplicity is not in general. Thus, this construction produces new examples of NSOP 1 not simple theories, and we study in depth a particular example: the expansion of an algebraically closed field of positive characteristic by a generic additive subgroup. The second part studies expansions of the groups of integers by p-adic valuations. We prove quantifier elimination in a natural language and compute the dp-rank of these expansions: it equals the number of distinct p-adic valuations considered. Thus, the expansion of the integers by one p-adic valuation is a new dp-minimal expansion of the group of integers. Finally, we prove that the latter expansion does not admit intermediate structures: any definable set in the expansion is either definable in the group structure or is able to "reconstruct" the valuation using only the group operation

Pełny tekst źródłaDie optische Nahfeldmikroskopie ermöglicht die zerstörungsfreie optische Unter- suchung von Oberflächen mit einer räumlichen Auflösung weit unterhalb des klas- sischen Beugungslimits von Abbe. Die Auflösung dieser Art von Mikroskopie ist unabhängig von der verwendeten Wellenlänge und liegt typischerweise im Bereich von 10-100 Nanometern. Auf dieser Längenskala zeigen viele Materialien optisch anisotropes Verhalten, auch wenn sie makroskopisch isotrop erscheinen. In der vorliegenden Arbeit wird die bisher noch nicht bestimmte Wechselwirkung einer streuenden Nahfeldsonde mit einer anisotropen Probe sowohl theoretisch als auch experimentell untersucht. Im theoretischen Teil wird das für isotrope Proben bekannte analytische Dipol- modell auf anisotrope Materialien erweitert. Während fÄur isotrope Proben ein reiner Materialkontrast beobachtet wird, ist auf anisotropen Proben zusätzlich ein Kontrast zwischen Bereichen mit unterschiedlicher Orientierung des Dielektrizitätstensors zu erwarten. Die Berechnungen zeigen, dass dieser Anisotropiekontrast messbar ist, wenn die Probe nahe einer Polaritonresonanz angeregt wird. Der verwendete experimentelle Aufbau ermöglicht die optische Untersuchung von Materialien im sichtbaren sowie im infraroten Wellenlängenbereich, wobei zur re- sonanten Anregung ein Freie-Elektronen-Laser verwendet wurde. Das dem Nahfeld- mikroskop zugrunde liegende Rasterkraftmikroskop bietet eine einzigartige Kombi- nation verschiedener Rastersondenmikroskopie-Methoden und ermöglicht neben der Untersuchung von komplementären Probeneigenschaften auch die Unterdrückung von mechanisch und elektrisch induzierten Fehlkontrasten im optischen Signal. An den ferroelektrischen Einkristallen Lithiumniobat und Bariumtitanat wurde der anisotrope Nahfeldkontrast im infraroten WellenlÄangenbereich untersucht. An eindomÄanigem Lithiumniobat wurden das spektrale Verhalten des Nahfeldsignals sowie dessen charakteristische Abhängigkeit von Polarisation, Abstand und Proben- orientierung grundlegend untersucht. Auf Bariumtitanat, einem mehrdomänigen Kristall, wurden analoge Messungen durchgeführt und zusätzlich Gebiete mit ver- schiedenen Domänensorten abgebildet, wobei ein direkter nachfeldoptischer Kon- trast aufgrund der Anisotropie der Probe nachgewiesen werden konnte. Die experimentellen Ergebnisse dieser Arbeit stimmen mit den theoretischen Vorhersagen überein. Ein durch die optische Anisotropie der Probe induzierter Nahfeldkontrast ist messbar und erlaubt die optische Unterscheidung von Gebie- ten mit unterschiedlicher Orientierung des Dielektriziätstensors, wobei eine Än- derung desselben sowohl parallel als auch senkrecht zur Probenoberfläche messbar ist. Diese Methode erlaubt die hochauflösende optische Untersuchung von lokalen Anisotropien, was in zahlreichen Gebieten der Materialwissenschaft, Speichertech- nik, Biologie und Nanooptik von Interesse ist

Pełny tekst źródłaDie Bildgebung mit THz Strahlung im Nanobereich ist höchst wünschenswert für genaue Materialuntersuchungen, welche nicht in anderen Spektralbereichen durchgeführt werden kann. Aufgrund des Beugungslimits ist kann jedoch mit klassischen Methoden keine bessere Auflösung als etwa 100 μm für THz-Strahlung erreicht werden. Die Methode der Streulicht-Nahfeldmikroskopie (s-SNOM) verspricht jedoch dieses Beugungslimit zu durchbrechen. In der vorliegenden Arbeit wird die Realisierung der Nahfeld-Mikroskopie und Spektroskopie im THz-Spektralbereich von 30–1500 μm (0.2–10 THz) präsentiert. Dies wurde mittels zweier grundsätzlich unterschiedlichen Strahlungsquellen an separaten Experimentaufbauten erreicht: Einer photoleitenden Antenne welche gepulste breitbandige THz-Strahlung von 0.2–2 THz emittiert, sowie einem Freie- Elektronen Laser (FEL) als schmalbandige hochleistungs Quelle, durchstimmbar von 1.3–10 THz. Mit dem photoleitenden Antennensystem konnte zum ersten mal demonstriert werden, dass mit breitbandigen THz-Pulsen Nahfeldspektroskopie möglich ist. Dazu wurde die übliche THz-Time-Domain-Spektroskopie (THz-TDS) zur Erhaltung der spektroskopischen s-SNOM Informationen, sowie asynchrones optisches Abtasten (ASOPS) für schnelle Fernfeld Spektroskopie eingesetzt. Die nahfeldspektroskopischen Fähigkeiten des Mikroskops wurden anhand von Messungen an Gold sowie unterschiedlich dotierten Siliziumproben demonstriert. Dabei konnte gezeigt werden, dass die spektrale Antwort den theoretischen Voraussagen des Drude- sowie Dipol Modells folgt. Während das breitband THz-TDS basierte s-SNOM spektroskopische Nahfelduntersuchungen zulässt, limitiert jedoch die schwache Ausgangsleistung der THz-quelle diese Technik insofern, dass praktisch nur Punktspektroskopie an ausgesuchten Probenstellen möglich ist. Für echte nanoskopische Nahfeldbildgebung wurde daher ein FEL als durchstimmbare hochleistungs THz-Quelle in Kombination mit der s-SNOM-Technik erforscht. Hierzu wurden die charakteristischen Nahfeld-Signaturen bei Wellenlängen von 35–230 μm untersucht, gefolgt von die Verwirklichung materialsensitiver THz Nahfeldbildgebung gezeigt an Goldstreifen mit bis zu 60 nm Auflösung. Dabei kann nicht nur das Gold von dem Glassubstrat unterschieden werden, sondern auch Ablagerungen als Überreste des Fabrikationsprozesses identifiziert werden. Um die Grenzen der Auflösungsmöglichkeiten dieser Technik zu sondieren, wurden weiterhin die Nahfelder von gemusterten Gold-Nanostrukturen (Fischer-Pattern) bei Wellenlängen bis zu 230 μm (1.2 THz) abgebildet. Hierbei wurde eine Auflösung von 50 nm festgestellt. Schliesslich konnte der topographieunabhängige Materialkontrast von eingebetteten organischen Strukturen, exemplarisch bei 150 μm Wellenlänge, gezeigt werden. Die Fähigkeit, spektroskopische Aufnahmen mittels der THZ-s-SNOM Technik zu erzeugen, wird der Grundlagenforschung und in der Nanotechnologie zu Gute kommen, und weiterhin Anwendungen in der Chemischen- und Halbleiterindustrie ermöglichen

Pełny tekst źródłaThe field of plasmonics is experiencing a rapid development, due to the interest in studying the behavior of light at the nanometer scale. Key ingredients of plasmonics are the surface plasmons (SPs), electromagnetic modes localized at the interface between a metal and a dielectric. SPs rely on the interaction between electromagnetic radiation and conduction electrons at metallic interfaces or in "small" metallic nanostructures. The recent intense activity on plasmonics has been also enabled by state-of-the-art nano fabrication techniques and by high-sensitivity optical characterization techniques. These tools pave the way to promising applications (integration in electronics, chemical and biological detection...), which exploit the SP peculiarity of confining optical fields over sub-wavelength mode volumes. The number of publications concerning plasmonics has been continuously increasing over the last twenty years giving rise to a dynamic research context. Several plasmonic devices have been demonstrated during the last years (modulators, couplers, detectors ...). However their integration is limited by the absence of a compact generator (electrical pumping, small dimensions) and by the huge ohmic losses. Standard techniques for surface plasmon polariton (SPP) generation need an external alignment with a laser source on a prism or on a grating. Our approach is based on semiconductor lasers sources with a transverse magnetic (TM) polarization. Therefore, it is possible to obtain compact semiconductor devices suitable for the on chip integration. During my thesis I studied experimentally and numerically the performance of a diode laser as a function of the metal distance from its active region. The proximity of the gain to the metal is necessary to realize active plasmonic devices. I demonstrated the generation and the amplification of SPP in the telecom range (λ=1.3µm) with compact semiconductor based devices, operating at room temperature and by electrical injection. I realized an elegant architecture with an integrated coupler grating for the SPP generation. The SPPs are directly accessible at the device surface. An ultra-thin cladding device allowed the demonstration of a hybrid plasmonic laser with a consistent fraction of electric field at the metal/semiconductor interface. Finally I demonstrated that the metal patterning allows a loss reduction, decreasing the laser threshold. The results are strengthened by a new near-field technique (NSOM) which permitted to measure the SPPs at the metal/air interface and at the metal/semiconductor interface. Thanks to the NSOM we showed unambiguously the effect of the metal patterning on the optical mode
