Revisão e proposta de melhoria do sistema de controlo interno da área de vendas do segmento empresarial da PT

O tema do Controlo Interno, tem uma importância crescente nos dias de hoje, como consequência do crescimento das empresas, a globalização dos mercados e a concorrência agressiva com que nos deparamos atualmente. As empesas têm assim maior necessidade de se adaptar rapidamente às mudanças e ter ferramentas internas que lhes permitam garantir a eficiência operacional melhorando os seus resultados. O objetivo geral deste projeto, teve como principal foco efetuar propostas de melhoria na atividade dos Comerciais de modo a ir ao encontro dos objetivos da empresa. Para tal, foi efetuado um levantamento dos processos internos existentes, onde se verificou que existem algumas lacunas no cumprimento das atividades dos comerciais, essencialmente devido ao estabelecimento de prioridades por parte dos comerciais, preferindo efetuar outras tarefas, mas também outros constrangimentos relacionados com falta de conhecimento. Foram então propostas melhorias que apesar de não terem sido colocadas ainda em prática, verificou-se através de um questionário que os coordenadores das equipas concordam com que as propostas de melhoria, se aplicadas levarão a um maior cumprimento dos objetivos da empresa. Com base nesse estudo, foi ainda elaborado um Guia de Venda de Soluções Empresarias como documento de informação e apoio aos Comercias.

Morfotectónica del segmento Cádiz-Málaga, sur de España.

Se presentan los resultados de una investigación morfotectónica del segmento continental de Cádiz a Málaga, zona occidental de interacción entre las placas africana y euroasiática. Aquí existe un sistema de 5 tipos de Unidades Territoriales (macrobloques= 2, mesobloques= 2, bloques= 29, microbloques= 44, y nanobloques= 202) en relaciones espacio-temporales actuales con una red de 29 alineaciones principales y 32 intersecciones o nudos. El 59% de los bloques es muy activo o activo, y el territorio tiene un valor de ~0.03 fracturas/km2 con 63 escarpes. Las zonas con mayor actividad están entre las localidades de Barbate-Torrecera-Sierra de las Cabras (en Cádiz) y Ronda-Embalse Gudaltela Cabras-Villalón (en Málaga). El segmento de Cádiz-Málaga tiene características similares a las de la zona colindante de Almería-Córdoba-Granada-Jaén-Murcia. Todo el trabajo sustentado en un SIG.

Constrained fuzzy power flow models with correlation between nodal injections

This paper extends the symmetric/constrained fuzzy powerflow models by including the potential correlations between nodal injections. Therefore, the extension of the model allows the specification of fuzzy generation and load values and of potential correlations between nodal injections. The enhanced version of the symmetric/constrained fuzzy powerflow model is applied to the 30-bus IEEE test system. The results prove the importance of the inclusion of data correlations in the analysis of transmission system adequacy.

Topological insulating phases from two-dimensional nodal loop semimetals

Starting from a minimal model for a two-dimensional nodal loop semimetal, we study the effect of chiral mass gap terms. The resulting Dirac loop anomalous Hall insulator’s Chern number is the phase-winding number of the mass gap terms on the loop.We provide simple lattice models, analyze the topological phases, and generalize a previous index characterizing topological transitions. The responses of the Dirac loop anomalous Hall and quantum spin Hall insulators to a magnetic field’s vector potential are also studied both in weak- and strong-field regimes, as well as the edge states in a ribbon geometry.

The Hitchin map for one-nodal base curves of compact type

Studying moduli spaces of semistable Higgs bundles (E, \phi) of rank n on a smooth curve C, a key role is played by the spectral curve X (Hitchin), because an important result by Beauville-Narasimhan-Ramanan allows us to study isomorphism classes of such Higgs bundles in terms of isomorphism classes of rank-1 torsion-free sheaves on X. This way, the generic fibre of the Hitchin map, which associates to any semistable Higgs bundle the coefficients of the characteristic polynomial of \phi, is isomorphic to the Jacobian of X. Focusing on rank-2 Higgs data, this construction was extended by Barik to the case in which the curve C is reducible, one-nodal, having two smooth components. Such curve is called of compact type because its Picard group is compact. In this work, we describe and clarify the main points of the construction by Barik and we give examples, especially concerning generic fibres of the Hitchin map. Referring to Hausel-Pauly, we consider the case of SL(2,C)-Higgs bundles on a smooth base curve, which are such that the generic fibre of the Hitchin map is a subvariety of the Jacobian of X, the Prym variety. We recall the description of special loci, called endoscopic loci, such that the associated Prym variety is not connected. Then, letting G be an affine reductive group having underlying Lie algebra so(4,C), we consider G-Higgs bundles on a smooth base curve. Starting from the construction by Bradlow-Schaposnik, we discuss the associated endoscopic loci. By adapting these studies to a one-nodal base curve of compact type, we describe the fibre of the SL(2,C)-Hitchin map and of the G-Hitchin map, together with endoscopic loci. In the Appendix, we give an interpretation of generic spectral curves in terms of families of double covers.

Plastias de estenoses de intestino delgado na doença de Crohn: resultados imediatos e tardios

BACKGROUND: Strictureplasty is an alternative surgical procedure for Crohn?s disease, particulary in patients with previous resections or many intestinal stenosis. AIM: To analyze surgical complications and clinical follow-up in patients submitted to strictureplasty secondary to Crohn?s disease. METHODS: Twenty-eight patients (57.1% male, mean age 33.3 years, range 16-54 years) with Crohn?s disease and intestinal stenosis (small bowel, ileocecal region and ileocolic anastomosis) were submitted to strictureplasty, at one institution, between September 1991 and May 2004. Thirteen patients had previous intestinal resections. The mean follow-up was 58.1 months. A total of 116 strictureplasties were done (94 Heineke-Mikulicz - 81%, 15 Finney - 13%, seven side-to-side ileocolic strictureplasty - 6%). Three patients were submitted to strictureplasty at two different surgical procedures and two in three procedures. RESULTS: Regarding to strictureplasty, postoperative complication rate was 25% and mortality was 3.6%. Early local complication rate was 57.1%, with three suture leaks (10.7%) and late complication was present in two patients, both with incisional hernial and enterocutaneous fistulas (28.6%). Patients remained hospitalized during a medium time of 12.4 days. Clinical and surgical recurrence rates were 63% and 41%, respectively. Among the patients submitted to another surgery, two patients had two more operations and one had three. Recurrence rate at strictureplasty site was observed in 3.5%, being Finney technique the commonest one. Presently, 19 patients had been asymptomatic with the majority of them under medical therapy. CONCLUSION: Strictureplasties have low complication rates, in spite of having been done at compromised site, with long term pain relief. Considering the clinical course of Crohn?s disease, with many patients being submitted to intestinal resections, strictureplasties should be considered as an effective surgical treatment to spare long intestinal resections.

Identificação eletrônica para avaliação do comportamento dos suínos na fase de gestação

The efficiency of swine production performance depends on the herd administration, such as good nutrition, sanitary control, facilities and appropriate environmental conditions. The concept of this production model is directly related with the reduction of selective losses and the process control. Each production segment is controlled to reach the optimization in the system totality, it is necessary to apply animals handling concepts, environmental control implementation, diseases control, nutrition control, information concerning in guaranteeing the animal welfare and individual identification.

The results obtained by the mathematical model, allowed to conclude accurately the evaluation of the swine thermal preference correlating with the climatic variables in the pregnancy stage.

Modelo de programação quadrática para análise da movimentação logística e comercialização da soja brasileira

The purpose of this work was to analyze the logistical distribution of Brazilian soybean by applying a quadratic programming to a spatial equilibrium model. The soybean transportation system is an important part of the soybean complex in Brazil, since the major part of the costs of this commodity derives from the transportation costs. Therefore, the optimization of this part of the process is essential to a better competitiveness of the Brazilian soybean in the international market. The Brazilian soybean complex have been increasing its agricultural share in the total of the exportation value in the last ten years, but due to other countries' investments the Brazilian exportations cannot be only focused on increasing its production but it still have to be more efficient. This way, a model was reached which can project new frames by switching the transportation costs and conduce the policy makers to new investments in the sector.
