This research was directed mainly towards the investigation of the reacti.ons of· substituted chlorobenziophenones under strongly basi,c conditions. The work 'can be divided into two main sections. The Introduction deals mainly with historical studies on aryne chemistry and the Haller-Bauer reaction. Secti.on I i.s concerned with syntheses of 2-benzamido-2'chlorobenzophenone and 2-benzamido~3'-chlorobenzophenone,and with thei,r respective reactions wi.th potassium amide in ammonia. o-Chlorophenylacetic acid was converted to the acid chloride and then by Friedel-Craftsreaction with benzene to w-(o-chlorophenyl)acetophenone. Reaction wi.th phenylhydrazine and Fischer cyclization gave 3- (0chlorophenyl)- 2-phenylindole, which was ozonized to 2-benzamido-2'chlorobenzophenone. The isomeric 3' -chlor,..o ke: tone was similarly synthesised from m-chlorophenylacetic acid. Both the 2'- and 3' -ch.loroketones gave N-benzoylacridone on treatment with potassium amide in ammonia; an aryne mechanism is involved for the 3'-chloroketone but aryne and nucleophilic substitution mechanisms are possible for the 2'-chloroketone. Hydrolysis of the 2'- and 3'-chloroketones gave 2-amino-2'chlorobenzophenone and 2-amino-3'-chlorobenzophenone respectively. A second new acridone synthesis is given in the Appendix involving reactions of these two ketones with potassium t-butoxide in t-butylbenzene. i Section 2 deals with the investigation of the reaction of some tricyclic ch1orobenzophenones with potassium amide in liquid ammonia. These were 1-ch1orof1uorenone; which was pr~pared in several steps from f1uoranthene, and 1- and 2-ch1oroanthraquinones. 1-Ch1orof1uorenone gave 1-aminof1uorenone ; 1-ch1oroanthraquinone gave 1- and 2-aminoanthraquinones; 2-ch1oroanthraquinone was largely recovered from the attempted reaction.

Volume(density)-independent pair-potentials cannot describe metallic cohesion adequately as the presence of the free electron gas renders the total energy strongly dependent on the electron density. The embedded atom method (EAM) addresses this issue by replacing part of the total energy with an explicitly density-dependent term called the embedding function. Finnis and Sinclair proposed a model where the embedding function is taken to be proportional to the square root of the electron density. Models of this type are known as Finnis-Sinclair many body potentials. In this work we study a particular parametrization of the Finnis-Sinclair type potential, called the "Sutton-Chen" model, and a later version, called the "Quantum Sutton-Chen" model, to study the phonon spectra and the temperature variation thermodynamic properties of fcc metals. Both models give poor results for thermal expansion, which can be traced to rapid softening of transverse phonon frequencies with increasing lattice parameter. We identify the power law decay of the electron density with distance assumed by the model as the main cause of this behaviour and show that an exponentially decaying form of charge density improves the results significantly. Results for Sutton-Chen and our improved version of Sutton-Chen models are compared for four fcc metals: Cu, Ag, Au and Pt. The calculated properties are the phonon spectra, thermal expansion coefficient, isobaric heat capacity, adiabatic and isothermal bulk moduli, atomic root-mean-square displacement and Gr\"{u}neisen parameter. For the sake of comparison we have also considered two other models where the distance-dependence of the charge density is an exponential multiplied by polynomials. None of these models exhibits the instability against thermal expansion (premature melting) as shown by the Sutton-Chen model. We also present results obtained via pure pair potential models, in order to identify advantages and disadvantages of methods used to obtain the parameters of these potentials.

Alors que les premiers romans de l’auteure sino-canadienne Ying Chen pouvaient aisément être rattachés à l’écriture migrante, ses dernières publications s’inscrivent moins clairement dans ce corpus. Pourtant, la critique les aborde encore généralement à partir de cette perspective. La présente étude a pour but d’analyser les romans de Chen qui mettent en scène la « même » narratrice anonyme à partir d’une approche plus appropriée, c’est-à-dire le thème de la cellule familiale. Les écrits féministes sur le rôle de la femme dans la société patriarcale ainsi que ceux sur le récit de filiation façonnent le regard porté sur les tensions au sein de la famille au fil de cette analyse. Le corpus à l’étude se compose du roman Immobile, qui met en scène une femme rejetant la filiation au profit d’ancêtres imaginaires, Le Mangeur qui se concentre sur une paternité étouffante et Un enfant à ma porte qui relate l’échec de la maternité.

Desde las etapas iniciales de la integración subregional andina se destacó la importancia del desarrollo de la capacidad tecnológica para la consecución de sus fines; de allí que se haya instituido un régimen común de propiedad intelectual junto con una estructura institucional y un conjunto de políticas públicas de complementariedad, entre las que se encuentra el régimen de inversión extranjera y derecho de la competencia. No obstante, desde que dichas normas comunitarias entraron en vigencia, generaron controversia por ir en oposición a las corrientes globales; situación que se agudizó a partir de los años 80, cuando los países de la región tuvieron que hacer frente a diversas dificultades, tanto exógenas como endógenas, que provocaron un debilitamiento en el proceso subregional andino e impulsaron cambios de política que fueron plasmados en el ordenamiento comunitario andino, hasta llegar a la Decisión 486, norma que representa la adecuación al sistema multilateral. El autor analiza los cambios de política en materia de propiedad intelectual que se dieron en la CAN en la última década, identificando su impacto en el proceso de integración subregional, al tiempo que estudia las políticas de propiedad intelectual, examinando los efectos de los desarrollos del sistema multilateral y las negociaciones bilaterales sobre el manejo de políticas de propiedad intelectual al interior de la Comunidad Andina, considerando las repercusiones que han tenido los TLC celebrados por Colombia y Perú con los Estados Unidos en esta materia.

É vasta a literatura em finanças quantitativas sobre o apreçamento de derivativos, porém é bem reduzida em se tratando de ações. Nessa dissertação, procuramos aplicar o modelo de Bakshi-Chen na avaliação de ações listadas na Bovespa. Os inputs do modelo são o lucro por ação, LPA, dos últimos doze meses, a expectativa de crescimento de lucro para os doze meses seguintes (g), e a taxa de juros. Vamos mostrar o ganho de precisão em relação ao modelo de Gordon e avaliar o modelo na prática realizando um backtest para descobrir se o modelo consegue estimar o valor das ações melhor do que os investidores.
