1. Missing for the last twenty years: the case of the southernmost populations of the Tropical Mockingbird Mimus gilvus (Passeriformes: Mimidae)
The Tropical Mockingbird Mimus gilvus (Vieillot, 1808) is a widespread species in the Neotropics, but its southernmost populations in Brazil are ecologically (and possibly taxonomically) distinct, occurring only along the coast in restinga vegetation. Once considered the most common bird in restinga, it is becoming increasingly rare, likely due to habitat lo

2. Avaliação da atividade neuroprotetora da Parawixina 11 isolada da peçonha da aranha Parawixia bistriata (Araneae, Araneidae), em ratos Wistar submetidos a um modelo de glaucoma agudo / Neuroprotective activity analysis of Parawixin 11, isolated from Parawixia bistriata (Araneae, Araneidae) spider venom, in Wistar rats submitted to an model of acute glaucoma
Glaucoma is defined as a typical optic neuropathy characterized by ganglion cells loss and consequent optic nerve damage, resulting in a gradual reduction of the visual field and eventual blindness. In regard to compounds present in spider venoms, they represent an interesting source of bioactive molecules and the study about the possible neuroprotective eff

3. Análise da Paisagem da Bacia Hidrográfica do Rio Tijucas, SC: Proposta de Áreas Prioritárias para um Sistema de Unidades de Conservação
The analysis of use and land cover is one of the key steps for conducting the strategic planning of conservation of a watershed. This work aims to analyze the landscape of the River Basin Tijucas for purposes of proposed priority areas for implementation of conservation, using as tool the Geographic Information System (GIS), aiming to provide support for pro

4. A fragmentação da flora nativa como instrumento de análise da sustentabilidade ecológica de áreas protegidas Espinhaço Sul (MG)
Increasing landscape fragmentation has contributed to biodiversity loss in various Brazilian regions and might be associated with unplanned human land occupation. Conservation and survival of most biological communities are dependent upon the spatial restructuring of landscape often limited to government protected areas. This constitutes the main mechanism u

5. Organic matter in Albaqualf as affected by managements irrigated rice cropping systems the South from Brazil / Matéria orgânica em Planossolo Háplico sob sistemas de manejo no cultivo do arroz irrigado no Sul do Brasil
In the south region from Rio Grande do Sul State, in,Brazil, 950 thousand hectares of soils are cultivated with rice, an important agricultural activity in that region, under an irrigation (flooded) system, using different soil management techniques. Studies regarding the organic matter (OM) dynamic in these soils are incipient, so this work aimed to evaluat

6. PERFORMANCE EVALUATION OF THE LOSS OF EXCITATION PROTECTION METHODS IN SYNCHRONOUS GENERATOR: A Contribution Using Fuzzy Set Theory / AVALIAÇÃO DO DESEMPENHO DOS MÉTODOS DE PROTEÇÃO CONTRA A PERDA DE EXCITAÇÃO EM GERADORES SÍNCRONOS: Uma Contribuição Utilizando a Teoria dos Conjuntos Nebulosos
Este trabalho visa avaliar o desempenho dos métodos de proteção contra a perda de excitação em geradores síncronos. Os métodos são apresentados de forma a tornar disponível em um único texto as diversas maneiras de se proteger o gerador síncrono contra a perda do seu sistema de excitação. Os métodos convencionais abordados apresentam alguns pro

7. For a socio-cultural history of abandonment and juveniles in Belo Horizonte 1921-1942. / Por uma história sócio-cultural do abandono e da delinqüência de menores em Belo Horizonte 1921-1941.
The purpose of this paper is to broach the historical and social production of representations about abandonment and the juvenilesdelinquency in Belo Horizonte between the years of 1921 and 1941. Through the approach of spaces, places and institutions specifically constructed for or appropriated by them, I tried to understand how the notion of delinquency an

8. Utilização de agrotoxicos em areas de reforma agraria no Estado do Parana
The pesticides are in an important technology and widely spread out after the Second World War. Theyare substances used in the whole world to control diseases transmitted by vectors or intennediate hosts and each time more, used in agriculture as the main strategy in the field for the protection of agricultural cultures. In Brazil, the pesticides were introd

9. Early trabeculectomy versus conventional management in primary open angle glaucoma.
The results of a randomised, prospective, multicentre trial of the management of primary open angle glaucoma are presented at up to five years' follow up. Previously undiagnosed cases were selected with intraocular pressure of 26 mmHg or more on two occasions together with field loss characteristic of glaucoma. Analysis was performed on one eye selected at r

10. Posttraumatic therapeutic vaccination with modified myelin self-antigen prevents complete paralysis while avoiding autoimmune disease
Spinal cord injury results in a massive loss of neurons, and thus of function. We recently reported that passive transfer of autoimmune T cells directed against myelin-associated antigens provides acutely damaged spinal cords with effective neuroprotection. The therapeutic time window for the passive transfer of T cells was found to be at least 1 week. Here
