Ce mémoire présente plusieurs contributions quant à l'analyse mathématique de l'équation de Gross-Pitaevskii et du modèle de Bogoliubov-Dirac-Fock. Au sujet de l'équation de Gross-Pitaevskii, l'analyse commence par la construction variationnelle des ondes progressives minimisantes. La preuve de la stabilité orbitale du soliton noir en dimension un, et la description de la limite transsonique des ondes progressives minimisantes vers les états fondamentaux de l'équation de Kadomtsev-Petviashvili en dimension deux, viennent compléter cette construction. L'analyse s'achève par la dérivation rigoureuse du régime ondes longues vers l'équation de Korteweg-de Vries en dimension un. Quant au modèle de Bogoliubov-Dirac-Fock, il s'agit de construire les états fondamentaux du modèle réduit, puis de préciser le processus de renormalisation de leur charge, lequel autorise le calcul d'un développement asymptotique de la densité de charges du vide polarisé, qui est cohérent avec les développements perturbatifs de l'électrodynamique quantique.

Cette thèse s'intéresse à la recherche de points rationnels sur les courbes elliptiques. Darmon et Logan ont proposé une construction conjecturale de points rationnels sur des courbes elliptiques modulaires définies sur un corps de nombres totalement réel. Cette construction va au delà de la construction classique des points de Heegner. C'est sur la généralisation de ces travaux que porte cette thèse. Après un premier chapitre de rappels concernant essentiellement les variétés de Shimura, on construit, dans le chapitre deux une forme différentielle dont l'ensemble des périodes est, sous une conjecture due à Yoshida, un réseau. On y définit aussi un ensemble de cycles dont la classe d'homologie est de torsion. A l'aide de ces données, on énonce au chapitre suivant une conjecture généralisant celle de Darmon et Logan. On s'interesse aussi aux propriétés de ces nouveaux points, principalement en lien avec les théorèmes "classiques" de Gross-Zagier et Gross-Kohnen-Zagier. Le chapitre 4 tente de rendre holomorphes les opérations du chapitre 2, et le chapitre 5 de les rendre plus explicites. Cette thèse comporte une annexe concernant les vérifications informatiques de la conjecture de Darmon.

<p>The study draws on secondary data from the Bureau of Statistics in Lesotho. Simple and multiple linear regression models techniques are used to analyze the relationship between the GDP of Lesotho and the GDP of manufacturing. The secondary data is analyzed using Statistical Packages for Social Sciences (SPSS) and Excel. The major finding is that there exists a strong positive linear relationship ( r = 0.986) between the GDP of Lesotho and the GDP of manufacturing. This means that every time the GDP of manufacturing increases the GDP of Lesotho does the same. Based on this finding, the study recommends that in order to improve, sustain and maintain the economic growth and to avoid further deterioration in the manufacturing industry, the manufacturing capacity must be strengthened for it to effectively deal with growing competition and rapid economic changes.</p>

The aim of this study is to investigate the impact of foreign direct investment (FDI) on economic growth in China during the period 1994-2003. The theoretical framework shows that FDI has a positive impact on economic growth because it serves as a channel through which new technology is transferred from one country to another and thereby it increases output and GDP in the recipient country. Previous researchers’ work on the subject has also been reviewed to be able to interpret the results. The research is based on secondary data for 30 different regions in China. The empirical results show a positive but insignificant effect of FDI as a fraction of GDP on the level of GDP when the regression model includes all 30 regions. When the four poorest regions that have almost no inflow FDI are excluded, the regression model continues to show a positive effect of FDI on the level of GDP and in addition, the result is statistically signifi-cant at the 6 % level. / Denna uppsats studerar utländska direkt investeringars påverkan på den ekonomiska till-växten i China under perioden 1994-2003. En teoretisk modell har utvecklats, som visar att utländska direktinvesteringar har en positiv inverkan på ekonomisk tillväxt, då de fungerar som en kanal via vilken ny teknologi överförs till från ett land till ett annat och därmed ökar produktion och BNP i det mottagande landet. Tidigare studier kring ämnet presente-ras också. Undersökningen är baserad på sekundär data för 30 olika regioner i Kina. De empiriska re-sultaten tyder på en positiv men icke-signifikant effekt av utländska direktinvesteringar som en del av BNP på BNP-nivån, när regressionsmodellen inkluderar alla 30 regioner. När de fyra fattigaste regionerna med ett näst intill obefintligt tillflöde av utlandsinvesteringar är utelämnade, visar regressionsmodellen ett signifikant resultat på 6 procents signifikantsnivå.

Heart valve dysfunction is a relatively common condition in the population, whereas significant heart valve disease is more unusual. The cause of different types of heart valve disease depends on which valve is concerned. Rheumatic heart valve disease, has for a long time been considered to constitute a post-inflammatory condition. During the 1990s it was also shown that the so-called non-rheumatic or degenerative tricuspid aortic stenosis, comprised signs of inflammation. In this study, 118 patients (the VOCIN study group) referred to the University Hospital for preoperative investigation due to significant heart valve disease, were examined regarding signs of inflammation. Twenty-nine aortic valves from patients with significant aortic stenosis were divided into tricuspid and bicuspid aortic valves. The bicuspid aortic stenotic valves revealed signs of inflammation to a similar extent as the tricuspid valves. However, the tricuspid and bicuspid valves differed regarding distribution of calcification. In contrast, inflammation was not a predominant feature in 15 aortic and mitral valves from patients with significant heart valve regurgitation. Gross valvular pathology consistent with rheumatic aortic stenosis was found in 10 patients. These valves revealed a somewhat lower degree of inflammatory cell infiltration, but on the whole, there were no substantial differences when compared to non-rheumatic aortic stenotic valves. They did, however, reveal a similar distribution of calcification as the bicuspid, non-rheumatic aortic valves. The VOCIN study group was compared to an age- and gender matched control group with regard to history and signs of rheumatic disease. There was not any increased prevalence of clinical manifestations of non-cardiac inflammatory disease in patients with significant heart valve disease, when compared to healthy control subjects. However, patients with heart valve disease had significantly increased serum levels of inflammatory markers compared to controls. The increase in inflammatory markers remained significant even in the subgroup of non-rheumatic aortic stenosis devoid of coronary artery disease. These results indicate that a systemic inflammatory component is associated with stenotic, non-rheumatic heart valve disease. The similarities between different forms of calcific aortic valve disease indicate a similar pathogenesis. The question is raised whether aortic stenosis is one disease, mainly caused by a general and non-specific response to dynamic tissue stress due to an underlying malformation of the valve.

This bachelor thesis in economics examines the Asian financial crisis, the impact on the countries in the region and how well they recovered financially. The countries that are taken into consideration are Japan, Indonesia, South Korea, Philippines, Thailand, Malaysia and Singapore.  The variables used to explain the implications of the crisis are GDP, trade openness, unemployment and current account. Descriptive statistics show that the most closed economy that was affected by a current account reversal was also the hardest hit in terms of GDP.  The statistics also show that all the countries under observation have recovered to their situation prior to the crisis in terms of GDP, but not in terms of the level of unemployment. Two regressions that were performed showed the relation between trade openness and the effect of GDP after the crisis, and the relation of trade openness to growth after the crisis. The regressions show that the more closed an economy is the larger the effect of a crisis. At the same time these countries had the highest growth rates after the crisis and were also among the first to recover. Theoretical reasons for these results are given.

The purpose of this paper is to examine the law regarding gross violations of women and its application in the Swedish legal system. We have investigated how the legal system takes into account a holistic perspective of the vulnerable situation of women in the investigation and assessment and the extent to which psychological violence in the form of verbal abuse, threats and harassment attention. We also wanted to find out how the law's design may contribute to difficulties in the implementation and interpretation of it. In this study, we used a qualitative research approach when we decided to conduct an interview with a police officer and a textual analysis of four cases from the district court. Interview questions were semi-structured in order to gain a deeper understanding of the phenomenon. The previous research we have chosen highlights how the law of gross violations of women came about, how gender is created and made visible in the legal system, and the criticism that has been leveled at the act's applicability. In the analysis of the empirical material we have used the four theoretical perspectives, commercial construction and interpretation of the law, social control, gender power structure and suppression techniques.A brief summary of the results we have found is that there is a clear gender power structure in the Swedish legal system that reinforces female subordination. The laws and the legal system standards are created and maintained by the male norm. The construction of the law contribute to difficulties in the application of the law when the methods that can be used when interpreting results in the judicial assessment performed on insufficient grounds due to subjective values​.We have also recognized a clear pattern that shows that the justice system does not apply a holistic approach in its analysis of the cases where only the physical violence is considered. When they pay attention to the psychological abuse it´s not considered being sufficient evidence for the men to be convicted of gross violations of women. Court cases show that woman's ability to prove the violence she has been subjected to the basis for the district court's judgment regarding the woman's self-esteem. In summary, the results of this study that there is an incorrect application of the law of gross violations of women that lead to women's situation is questioned and the men are not expected to commit the offense was considered to be the reason for the introduction of this law. This occurs due to psychological violence is not considered in the same way as the physical violence which is the basis for how the self-esteem to be valued. / Syftet med detta examensarbete är att undersöka lagen om grov kvinnofridskränkning och dess tillämpning i det svenska rättssystemet. Vi har undersökt hur rättsväsendet beaktar ett helhetsperspektiv av den utsatta kvinnans situation vid utredning och bedömning samt i vilken utsträckning det psykiska våldet i form av verbala kränkningar, hot och ofredande uppmärksammas. Vi ville även ta reda på hur lagens konstruktion kan bidra till svårigheter vid tillämpningen och tolkningen av den. I denna studie har vi använt oss av en kvalitativ forskningsstrategi då vi valt att genomföra en intervju med en polis och en textanalys av fyra stycken rättsfall från tingsrätten. Intervjufrågorna har varit semistrukturerade för att få en djupare förståelse för fenomenet. Den tidigare forskning vi valt att presentera belyser hur lagen om grov kvinnofridskränkning kom till, hur genus skapas och synliggörs i rättssystemet samt den kritik som har framförts mot lagens tillämplighet. Vid analysen av det empiriska materialet har vi använt oss av fyra stycken teoretiska perspektiv, rättens konstruktion och tolkning av lagen, social kontroll samt könsmaktsordning och härskartekniker. En kort sammanfattning av det resultat vi kommit fram till är att det finns en könsmaktsordning i det svenska rättssystemet som befäster kvinnans underordning vid tillämpningen och tolkningen av lagen. Lagarna och rättssystemets normer skapas och bibehålls utifrån den manliga normen. Lagkonstruktion bidrar till svårigheter vid tillämpningen av lagen då de metoder som kan användas vid tolkningen leder till att rättsväsendets bedömningar utförs på otillräckliga grunder till följd av subjektiva värderingar. Vi har även urskiljt tydliga mönster som visar på att rättsväsendet inte tillämpar ett helhetsperspektiv i sin bedömning av fallen då endast det fysiska våldet beaktas. När de psykiska övergreppen uppmärksammas anses inte bevisen vara tillräckliga för att männen ska kunna dömas för grov kvinnofridskränkning. I rättsfallen synliggörs det att kvinnans möjlighet att bevisa det våld hon blivit utsatt för ligger till grund för tingsrättens bedömning gällande kvinnans självkänsla. Sammanfattningsvis är resultatet av denna studie att det sker en felaktig tillämpning av lagen om grov kvinnofridskränkning som leder till att kvinnornas situation ifrågasätts och männen döms inte till det brott som ansågs vara anledningen till införandet av denna lag. Detta sker till följd av att det psykiska våldet inte beaktas i samma utsträckning som det fysiska våldet vilket ligger till grund för hur självkänslan ska värderas.
