| La presente tesis gira en torno a la tematica de las posibles causas y las consecuencias del alto porcentaje de la práctica de cirugías estéticas en la Ciudad de Buenos Aires - a nivel cultural, social y personal. El análisis se basa en el trabajo de campo antropológico, realizado en los períodos comprendidos entre septiembre de 2004 y febrero de 2005, y entre agosto 2006 y abril 2007. La tesis empieza con una indagación sobre el contexto histórico y sociocultural en que ocurre el fenómeno de las populares intervenciones (quirúrgicas) corporales para embellecer. ¿Porqué existe semejante popularidad para el cuerpo bello y las prácticas (quirúrgicas) de embellimiento en Buenos Aires? Por un lado, este contexto se ve influido por procesos globales,... |

| The ability to incorporate and manage the different drivers of land-use change in a modeling process is one of the key challenges because they are complex and are both quantitative and qualitative in nature. This paper uses Bayesian belief networks (BBN) to incorporate characteristics of land managers in the modeling process and to enhance our understanding of land-use change based on the limited and disparate sources of information. One of the two models based on spatial data represented land managers in the form of a quantitative variable, the area of individual holdings, whereas the other model included qualitative data from a survey of land managers. Random samples from the spatial data provided evidence of the relationship between the different... |

| A avaliação da qualidade fisiológica de sementes é um aspecto importante para o controle das plantas daninhas. Objetivou-se verificar a viabilidade de sementes de Euphorbia heterophylla resistentes e suscetíveis a herbicidas, após serem armazenadas durante 14 meses, por meio da aplicação dos testes de germinação e tetrazólio. Foi analisada a germinação na ausência e presença de luz, em temperatura constante (25 ºC). Para o teste de tetrazólio, as sementes foram seccionadas longitudinal-diagonalmente, colocadas em placas de Petri contendo solução de tetrazólio a 1%, envoltas em papel-alumínio e mantidas a 30 ºC, no escuro e em estufa, por 18 horas. Não foram observadas diferenças significativas entre os biótipos resistentes e suscetíveis de E. heterophylla... |

| O objetivo deste estudo foi verificar os efeitos do chlorimuron-ethyl, inibidor da enzima acetolactato sintase (ALS), no crescimento foliar (largura e comprimento) e em altura de plantas de Euphorbia heterophylla suscetíveis e resistentes aos herbicidas inibidores da ALS, aos 30 dias após a aplicação do herbicida. O experimento foi conduzido em casa de vegetação, utilizando-se o delineamento inteiramente casualizado, com 11 repetições por dose aplicada do herbicida. Foram observadas respostas diferenciais entre os biótipos. As características analisadas variaram segundo a dose utilizada do herbicida. Nenhuma das doses experimentais, incluindo a comercial, foi capaz de controlar, eficientemente, o desenvolvimento das plantas resistentes. |

| *Objective:* Methods were invented that made it possible to image peripheral nerves in the body and to image neural tracts in the brain. Over a 15 year period, these techniques – MR Neurography and Diffusion Tensor Imaging – were then deployed in the clinical and research community and applied to about 50,000 patients. Within this group, about 5,000 patients having MR Neurography were carefully tracked on a prospective basis.

*Method:* In the study group a uniform imaging methodology was applied and all images were reviewed and registered by referral source, clinical indication, efficacy of imaging and quality. Various classes of image findings were identified and subjected to a variety of small... |

| En el presente trabajo se estudiaron los artrópodos carroñeros que acudieron a cadáveres de vertebrados al aire libre en la provincia de San Juan, Argentina. El objetivo fue inventariar la composición específica de la artropodofauna cadavérica, asociada a diferentes sustratos de vertebrados en descomposición. Se colectaron muestras de artrópodos sobre restos animales y humanos en condiciones de campo y sobre cadáveres de cerdos domésticos colocados al aire libre bajo condiciones controladas. Se registraron, por primera vez para la provincia de San Juan, 40 especies de artropodofauna tanatológica incluidas en cuatro órdenes y 15 familias. Se incorpora, como primera cita para la fauna forense argentina, un necrófago: Megelenophorus americanus Lacordaire... |

| This study on the "distribution and future of persistent contaminants in coastal ecosystems, comparison between the western Channel and the eastern Channel" was carried out by the Ifremer for the Water Agency of Seine-Normandie. It provides information on the level of relatively well-known and regulated contaminants (cadmium, mercury, lead, BPC, dioxins, PAH) in sea products, as well as on that of less systematically recorded substances (silver, copper, nickel, zinc, polybrominated biphenyls, ethers, alkylphenols, phtalats). The Lower-Norman coast, from the Seine estuary and the Mont Saint-Michel, is particularly interesting for this study since this limited geographic area is home to the most extreme levels of contamination recorded along the entire... |

| The log export policy suggestion by Dumont and Wright (2006) is critically assessed in an effort to determine if it is based on economic efficiency. The optimal log export policy for British Columbia is derived using two different models. The first model assumes that B.C. is a small open economy, and the second is a two country model that provides B.C. the opportunity to improve its terms of trade. In both cases it is shown that an optimal log export tax when a fixed lumber export tax exists can be characterized as a problem of second best. In that scenario the optimal log export policy is a positive export tax in both models. In the second model a positive export tax is also optimal when there is no lumber export tax, but it is smaller than when the... |

| A canvass of the resource economics literature of the last thirty years yields a limited number of applications of economic theory to the problems of recreational fishing, especially compared to the depth of contributions to commercial fisheries over this era. This neglect may be linked to the relatively short shrift given to the control of recreational fisheries (relative to commercial fisheries) by fisheries managers in the past. This asymmetry may be justified when recreational takes are sufficiently small to be negligible for the purposes of stock management. However, it has become increasingly clear that recreational mortality, far from being insignificant, is often comparable to or greater than the commercial mortality for many species (Coleman, et... |

| The latest round of multilateral trade negotiations was launched at the ministerial meeting of the World Trade Organization in Doha, Qatar, in November 2001. Agriculture is a major item on the agenda for the Doha Round. The primary focus is on the three “pillars” of the Uruguay Round agreement—domestic support, market access, and export competition. The framework for a final agreement was finalized at a Ministerial meeting in Geneva in July 2004, but contains few details on modalities (e.g., the formula to be used for reductions in tariffs/increases in tariff-rate quotas, quantitative limitations on domestic support, and the schedule for the elimination of export subsidies). Detailed proposals on a number of these issues were put forward in October 2005... |

| Two field experiments were conducted at the experimental farm of the National Research Centre at Shalakan, Kalubia Governorate, Egypt, during 2006 and 2007 seasons, to study the effect of three pre-emergence herbicides, prometryn [at the rate of 0.75, 1.5 and 2.25 kg ha-1], oxadiargyl [at the rate of 240, 480 and 720 g ha-1] and butralin [at the rate of 1.20, 2.40 and 3.36 kg ha-1], two hand hoeing treatments and a nonweeded check, on weed infestation, nodulation, growth, yield and yield attributes of soybean plants. Two hand hoeing treatments resulted in the highest weed depression expressed as the lowest fresh and dry weights of broadleaved, grassy and total weeds. The reduction percentage in weed dry matter compared to the nonweeded treatment was 98.3,... |
