Travel time tomographic studies of seismic structures around subducted lithospheric slabs

The nature of the subducted lithospheric slab is investigated seismologically by tomographic inversions of ISC residual travel times. The slab, in which nearly all deep earthquakes occur, is fast in the seismic images because it is much cooler than the ambient mantle. High resolution three-dimensional P and S wave models in the NW Pacific are obtained using regional data, while inversion for the SW Pacific slabs includes teleseismic arrivals. Resolution and noise estimations show the models are generally well-resolved.

The slab anomalies in these models, as inferred from the seismicity, are generally coherent in the upper mantle and become contorted and decrease in amplitude with depth. Fast slabs are surrounded by slow regions shallower than 350 km depth. Slab fingering, including segmentation and spreading, is indicated near the bottom of the upper mantle. The fast anomalies associated with the Japan, Izu-Bonin, Mariana and Kermadec subduction zones tend to flatten to sub-horizontal at depth, while downward spreading may occur under parts of the Mariana and Kuril arcs. The Tonga slab appears to end around 550 km depth, but is underlain by a fast band at 750-1000 km depths.

The NW Pacific model combined with the Clayton-Comer mantle model predicts many observed residual sphere patterns. The predictions indicate that the near-source anomalies affect the residual spheres less than the teleseismic contributions. The teleseismic contributions may be removed either by using a mantle model, or using teleseismic station averages of residuals from only regional events. The slab-like fast bands in the corrected residual spheres are are consistent with seismicity trends under the Mariana Tzu-Bonin and Japan trenches, but are inconsistent for the Kuril events.

The comparison of the tomographic models with earthquake focal mechanisms shows that deep compression axes and fast velocity slab anomalies are in consistent alignment, even when the slab is contorted or flattened. Abnormal stress patterns are seen at major junctions of the arcs. The depth boundary between tension and compression in the central parts of these arcs appears to depend on the dip and topology of the slab.

Financial and Economic Report of a Specific Business Group

As a result of the natural evolution of the economy, ever-changing, unpredictable and cyclical, companies must adapt as far as possible to the changes that have taken place in order to continue with their normal operating activities. Likewise, they should also try to maintain a structure for long-term growth, trying at all times to generate the maximum value. The main objective of this project is to provide financial advisory services to a business group, trying to forward solutions and measures that according to the author can be effective. For this end, the situation of the group in question is analysed from early 2008 to the present day, examining its evolution, what steps have been taken together with their corresponding results and the economic-financial situation of the company at the end of last year. Contact with the company was kept throughout the process of analysis and assessment trying to take advantage of the feedback generated so that the appropriate measures can be adopted if the management considers it to be adequate.

A business plan development: the case of a paint company in Douala Camroon by Bomboy & Friends

This paper presents a business plan to create a new company Bomboy & Friends regarding the Exclusive Distribution of a fully Eco Friendly Water-Soluble Anti- Corrosive Prime named Life Guard Active Rust Primer Paint abbreviated as “L.G.A.R.P Paint” in Douala Cameroon and the C.E.M.A.C Region. The lack of quality paint in Cameroon has given the opportunity for a company like Bomboy & Friends to nurture its existence and be part of a fast growing economy, providing a high quality paint competition, very economical, easy to prepare, environmentally friendly, compatible with other brands and accessible to medium and small size companies.

Medicina tecnológica, cuidado e business: estudo sobre a prática dos médicos oncologistas no Brasil

Esta tese consiste em um estudo sobre o trabalho e a prática médica observados a partir do tipo ideal Werberiano da medicina tecnológica qual seja: a prática médica especializada, equipada e fragmentada, que começou a ser exercida no Brasil apartir nos anos sessenta. Elegemos para esse estudo médicos oncologistas clínicos inseridos em serviços públicos e privados de saúde. A eleição dos oncologistas clínicos se deu pelo reconhecimento da oncologia como uma prática muito especializada e amparada por equipamentos e procedimentos que se fortaleceu no Brasil na década de sessenta.Pretendeu-se compreender as singularidades dessa prática focalizando a formação, o tipo de cuidado ofertado aos pacientes, a inserção dos médicos no mercado público e privado e a relação entre eles. Inicia-se com uma abordagem geral da prática médica baseada no saber sobre as doenças, no processo histórico e cultural da apreensão desta prática e suas repercussões na sociedade e no mercado de trabalho. Em seguida apresentamos uma revisão sumária da trajetória da oncologia no Brasil, a representação social do câncer, as políticas de saúde da área e a relação entre os médicos, o estado e a sociedade nesse campo. Esse conjunto foi caracterizado como Projeto Médico Oncológico.Utilizou-se, no trabalho de campo, a pesquisa qualitativa e empregou-se como técnica entrevistas com seis profissionais médicos oncologistas que trabalham no Instituto Nacional do Câncer e no setor privado de saúde. Foi realizada uma entrevista piloto visando apresentar na íntegra os temas abordados nas demais entrevistas. A partir do olhar e das reflexões dos médicos são apresentadas quatro categorias para discussão e considerações. Finalizando o estudo apresenta através das categorias obtidas no trabalho de campo uma problematização do modelo idealizado na medicina tecnológica.
