Another objective is to introduce various investment instruments, and because that the thesis discusses investing of real funds, the emphasis is on the list of risks and possibilities of their elimination.

A new understanding of the damage formation mechanisms in Si is developed and investigated over an extended range of ion energy, dose, and irradiation temperature. A simple model for dealing with ion-induced damage is proposed, which is shown to be applicable over the range of implantation conditions. In particular the concept of defect "excesses" will be discussed. An excess exists in the lattice when there is a local surplus of one particular type of defect, such as an interstitial, over its complimentary defect (i.e., a vacancy). Mechanisms for producing such excesses by implantation will be discussed. The basis of this model specifies that accumulation of stable lattice damage during implantation depends upon the excess defects and not the total number of defects. The excess defect model is validated by fundamental damage studies involving ion implantation over a range of conditions. Confirmation of the model is provided by comparing damage profiles after implantation with computer simulation results. It will be shown that transport of ions in matter (TRIM) can be used effectively to model the ion-induced damage profile, i.e. excess defect distributions, by a simple subtraction process in which the spatially correlated defects are removed, thereby simulating recombination. Classic defect studies illuminate defect interactions from concomitant implantation of high- and medium-energy Si+-self ions. Also, the predictive quality of the excess defect model was tested by applying the model to develop several experiments to engineer excess defect concentrations to substantially change the nature and distribution of the defects. Not only are the excess defects shown to play a dominant role in defect-related processing issues, but their manipulation is demonstrated to be a powerful tool in tailoring the implantation process to achieve design goals. Pre-amorphization and dual implantation of different energetic ions are two primary investigative tools used in this work. Various analyses, including XTEM, RBS/channeling, PAS, and SIMS, provided experimental verification of the excess defect model disseminated within this dissertation.

Apesar de a monogamia social ser dominante entre as aves, análises genéticas revelaram relações de parentesco inesperadas, evidenciando diferentes estratégias de reprodução, como a paternidade extra-par e o parasitismo de ninho. Espécies de passeriformes estão entre as mais promíscuas, com altas taxas de paternidade extra-par, enquanto em aves marinhas esse comportamento demonstrou ser menos frequente. Pinguins (Família Spheniscidae) compõem um grupo de 18 espécies de aves marinhas pelágicas e que tem em comum a filopatria, fidelidade a um parceiro e intenso cuidado biparental. Portanto, espera-se que apresentem um comportamento estritamente monogâmico e taxas de paternidade extra-par insignificantes. Avaliamos pela primeira vez o sistema reprodutivo dos Pinguins-de-Magalhães através de uma abordagem genética, buscando investigar a existência e frequência de paternidade extra-par e parasitismo de ninho. O parentesco de 88 filhotes de 44 ninhos de uma colônia na Ilha Quiroga (Argentina) foi determinado com base em análises de 9 marcadores microssatélites. Encontramos baixas taxas de parasitismo de ninho (6%), mas altas taxas de paternidade extra-par (31% e 48% dos ninhos com pelo menos 1 filhote extra-par). Entre os dois anos coletados, encontramos uma pequena diferença na incidência de infidelidade (29% em 2010; 32% em 2011), mas não houve relação com as condições climáticas do período de reprodução da espécie. Além disso, apesar da alta taxa de filhotes extra-par, não encontramos diferença significativa na diversidade genética e nem viés da razão sexual secundária. Acreditamos que a alta taxa de paternidade extra-par encontrada possa ter relação com o comportamento reprodutivo em colônia, a densidade populacional, o sincronismo reprodutivo, ou que parte da paternidade que não correspondeu aos pais sociais seja resultado de troca de parceiros antes da definição final dos casais em cada estação reprodutiva. Nosso estudo pode ajudar a melhor entender e caracterizar o sistema reprodutivo dos Pinguins-de-Magalhães e indica que a espécie é socialmente, mas não geneticamente monogâmica. / Despite the social monogamy being dominant among birds, genetic analysis revealed unexpected kinship relations, showing different reproductive strategies, such as extra-pair paternity and brood parasitism. Passerine species are among the most promiscuous, with high extra-pair paternity rates, while in seabirds this behavior is typically rather less frequent. Penguins (Spheniscidae Family) are a group of 18 species of pelagic seabirds that have in common philopatric behavior, faithfulness to one partner and intense biparental care. Therefore, they are expected to have a strictly monogamous behavior and insignificant rates of extra-pair paternity. For the first time, we evaluated the reproductive system of Magellanic Penguins (Spheniscus magellanicus) through genetic analysis in order to investigate the existence and frequency of extra-pair paternity and brood parasitism. The kinship of 88 offspring of 44 nests from a colony on Quiroga Island (Argentina) was determined based on the analyses of 9 microsatellite markers. We found low rates of brood parasitism (6%), but high extra-pair paternity rates (31% and 48% of nests with at least one extra-pair offspring). Between the two years sampled, we found a small difference in the incidence of infidelity (29% in 2010; 32% in 2011), but no connection with the climatic conditions of each breeding season. In addition, despite the high rate of extra-pair offspring, we found no significant difference in the genetic diversity and no bias in the secondary sex ratio. We believe that the high rate of extra-pair paternity found in our study may be a result of their reproductive behavior of nesting in colonies, breeding synchrony, density, or that part of the mismatching paternity is due mate switching. Our study may help to better understand and characterize the reproductive system of Magellanic penguins and indicates that this species is socially but not sexually monogamous.

O ruído ambiental será abordado neste trabalho, com uma visão interdisciplinar, como fonte indutora de incômodos e/ou prejuízos à comunidade, especialmente à saúde das pessoas. Serão apresentadas as principais fontes de ruído ambiental e o nível de pressão sonora de cada fonte, respectivamente. Neste contexto, serão estudadas as repercussões do ruído ambiental para as pessoas em geral e os principais métodos de atenuação deste impacto ambiental. Este trabalho fará um levantamento das principais legislações sobre ruído ocupacional, e suas aplicações específicas.

Apresentar-se-á uma evolução histórica da legislação laboral e previdenciária. Finalmente será estabelecido como esta fonte física de agressão à saúde do trabalhador se repercute na vida pessoal do obreiro, na empresa em que trabalha e no sistema previdenciário brasileiro, e em especial na indústria metalúrgica. / This study addresses the environmental noise as an important source of nuisance and/or losses to the community - particularly to peoples health - from an interdisciplinary standpoint. The main sources of environmental noise and the level of sound pressure of each source are addressed as well. In this context, this paper investigates the repercussion of environmental noise on individuals and the main methods of mitigating such impact, also including a survey on the main laws on occupational noise and their specific applications. This study also aims at consolidating the environmental noise concepts as to their diversified applications and scientific interpretation. A special chapter is dedicated to the impact of occupational noise on workers exposed to high sound pressure. It addresses the Noise-Induced Hearing Loss (PAIR); Hearing Loss Caused by Occupational Noise (PAIRO), and Hearing Loss Caused by High Sound Pressure (PAINPSE). A historical evolution of labor and retirement laws is also presented. The study will conclusively establish how this physical source of aggression to the laborers health impacts his/her personal life, his company, and the Brazilian retirement system, and especially in the metallurgical industry.

Due to its ubiquitous availability, Short Message Service (SMS), first introduced in the 1980s, became not only the most popular way of communication, but also stimulated the development of SMS-based value added services. This application-to-person traffic is delivered to end users through SMS aggregators who provide the link between service providers and mobile carriers. In order to perform optimal traffic routing, the aggregators need to estimate the quality of each potential international route to the specified destination. The evaluation criteria include end-to-end delivery time, as well as correct verification of delivered data. This thesis suggests a method of quality of service (QoS) assessment for international SMS service which combines two types of tests, end-to-end delay measurements and various verification tests. A prototype of the testing system for international SMS service was developed to generate SMS traffic, collect and analyze results, and evaluate the experienced QoS of the SMS route used in accordance with the proposed approach. As a part of end-to- end delay measurement tests, SMS traffic was sent to Singtel network in Singapore along two routes. The verification tests were executed via different routes to two mobile networks: Singtel and Tele2 (Sweden). The results of the performed measurements determined the route with the highest QoS, i.e. the one with bigger bottleneck bandwidth and lower data loss rate. The prototype of the SMS testing system can be used by SMS aggregators to verify delivery of a SMS message, check the integrity of the message, figure out interconnection type of the route supplier with the destination carrier and to identify the presence of load balancers in the path. The prototype also makes it possible to compare end-to-end delay times of several routes and compute bottleneck values for each of the tested routes.

Programming practices are used to improve various attributes of the coding process. Pair and Mob Programming are two practices that involve multiple developers collaboratively working on the same tasks and share multiple advantages and disadvantages. The aim of this project is to identify common advantages and disadvantages of the two practices as well as some attributes that differentiate the two and help in the process of deciding which programming practice should be used for a task. The first method used to answer the research questions was a literature review that should find and list the pros and cons of Mob and Pair Programming. A second method used were interviews with industry practitioners, whose perspectives and experiences will validate the previous results, add new attributes to the practices and identify differences and factors that encourage the use of one or the other practice. The findings of the project consist of positive and negative aspects of using any of the two programming practices and a set of attributes that should be considered when deciding whether to adopt Mob or Pair Programming for the task at hand.
