Lagos artificiais urbanos consolidados: efetivação de suas áreas de preservação permanente e o direito de propriedade: o caso do Lago Paranoá de Brasília

A presente monografia detectou a necessidade de alteração do Artigo 2º do Código Florestal (Lei nº. 4.771, de 15 de setembro de 1965), que recepcionou Áreas de Preservação Permanentes (APPs) de corpos d’água lênticos naturais e artificiais, tais como as lagoas e lagos ou reservatórios d’água artificiais urbanos e rurais, respectivamente, denominadas pela doutrina como APPs Legais. Já o artigo 3º considerou ainda de preservação permanente as florestas e demais formas de vegetação declaradas pelo poder público, consideradas portanto pela doutrina como APPs administrativas. As APPs legais, com efeito, não são onerosas face às limitações genéricas e de interesse público, por isso não suportam indenização, não ferindo o direito de propriedade consubstanciado na sua função socioambiental. Ao contrário, as APPs administrativas são onerosas e estão sujeitas à justa indenização para sua efetivação em propriedades determinadas. Nesse caso, o fato de o art. 2º ter recepcionado as APPs dos lagos artificiais urbanos como APPs legais, fez com que o legislador incorresse em equívoco, o que merece indispensável correção, passando esta modalidade de APP a ser elencada no art. 3º da citada lei. Com essa correção de locação no artigo 3º dessa modalidade de APP, os proprietários de imóveis urbanos adjacentes a reservatórios artificiais urbanos, cujos limites alcançam a lâmina d’água do reservatório, para disposição desse espaço como APP (30 m.), passam a ter a possibilidade de ser indenizados, por tratar-se de restrição administrativa onerosa. Esta monografia enfocou a necessidade de alteração do Código Florestal por meio de dados e informações oriundas de revisão bibliográfica e de resultado de observações pessoais. Constatou, portanto, a necessidade de alteração da legislação ambiental, no tocante a letra “b”do artigo 2º do referido código.The present monograph detected the necessity of article’s alteration on the article 2º of the Forest Code that received Permanent Areas of Preservation- APP(s)- of natural and artificial water bodies stopped, such as the urban and agricultural lagoons and lakes or artificial water reservoirs, respectively, called for the doctrine as legal APP(s). Already the article 3º still considered of permanent preservation the forests and too much forms of vegetation declared by the Public Power, considered, therefore, for the doctrine as administrative APP(s). The legal APP(s), with effect, are not onerous face to the generic limitations and public interest; therefore they do not support indemnity, not wounding the right of property consolidated in the socioambiental function. In contrast, the APP(s) administrative are onerous and citizens to the joust indemnity for its accomplishment in definitive properties. In this case, the fact of the article 2º had recepcioned the APP(s) of the urban artificial lakes as legal areas, made the legislator incurring into mistake, that it deserves indispensable correction, passing this modality of area to be displayed in the article 3º of the cited law. With this correction of location in the article 3º in this modality of APP, the urban proprietors of adjacent urban property and artificial reservoirs, whose limits reach the water blade of the reservoir for disposal of this space as APP (30meters), starts to have the possibility to being indemnified, because it is case of onerous administrative restriction. This monograph studied the importance of necessity of alteration in Forest Code by means data and deriving information of bibliographical revision and personal comments’s result. It evidenced, therefore, the necessity of alteration in ambient legislation in moving to letter "b" of the article 2º of the related Code

A spatiotemporal statistical atlas of motion for the quantification of abnormal myocardial tissue velocities

International audienceIn this paper, we present a new method for the automatic comparison of myocardial motion patterns and the characterization of their degree of abnormality, based on a statistical atlas of motion built from a reference healthy population. Our main contribution is the computation of atlas-based indexes that quantify the abnormality in the motion of a given subject against a reference population, at every location in time and space. The critical computational cost inherent to the construction of an atlas is highly reduced by the definition of myocardial velocities under a small displacements hypothesis. The indexes we propose are of notable interest for the assessment of anomalies in cardiac mobility and synchronicity when applied, for instance, to candidate selection for cardiac resynchronization therapy (CRT). We built an atlas of normality using 2D ultrasound cardiac sequences from 21 healthy volunteers, to which we compared 14 CRT patients with left ventricular dyssynchrony (LVDYS). We illustrate the potential of our approach in characterizing septal flash, a specific motion pattern related to LVDYS and recently introduced as a very good predictor of response to CRT

Atlas-based Quantification of Myocardial Motion Abnormalities: Added-value for the Understanding of CRT Outcome?

International audienceIn this paper, we present the use of atlas-based indexes of abnormality for the quantification of cardiac resynchronization therapy (CRT) outcome in terms of motion. We build an atlas of normal motion from 21 healthy volunteers to which we compare 88 CRT candidates before and after the therapy. Abnormal motion is quantified locally in time and space using a statistical distance to normality, and changes induced by the therapy are related with clinical measurements of CRT outcome. Results correlate with recent clinical hypothesis about CRT response, namely that the correction of specific mechanisms responsible for cardiac dyssynchrony conditions the response to the therapy

Biochar and soil nitrous oxide emissions

The objective of this work was to evaluate the effect of biochar application on soil nitrous oxide emissions. The experiment was carried out in pots under greenhouse conditions. Four levels of ground commercial charcoal of 2 mm (biochar) were evaluated in a sandy Albaqualf (90% of sand): 0, 3, 6, and Mg ha-1. All treatments received 100 kg ha-1 of N as urea. A cubic effect of biochar levels was observed on the N 2O. Biochar doses above 5 Mg ha-1 started to mitigate the emissions in the evaluated soil. However, lower doses promote the emissions.The objective of this work was to evaluate the effect of biochar application on soil nitrous oxide emissions.

Antioxidant, anti-acetylcholinesterase and cytotoxic activities of ethanol extracts of peel, pulp and seeds of exotic Brazilian fruits Antioxidant, anti-acetylcholinesterase and cytotoxic activities in fruits

Ethanol extracts of powdered genipap (Genipa americana L), umbu (Spondia tuberosa A.) and siriguela (Spondia purpurea L) prepared from separate pulp, seeds and peel were investigated for their (i) antioxidant capacity, which was evaluated by various known methods; (ii) acetylcholinesterase (AChE) inhibitory activity; and (iii) cytotoxic effect on corneal epithelial cells of sheep. the highest values of total phenolic content were obtained with peel and seed extracts. Siriguela and umbu (seeds and peel) extracts displayed the highest antioxidant activities. Lipid peroxidation assays using mimetic biomembranes and mouse liver homogenates indicated that genipap pulp is a promising antioxidant. the investigation of phenols and organic acid contents revealed the presence of quercetin, citric and quinic acids, chlorogenic acid derivatives, among others, in several extracts, with the highest amount found in siriguela seeds. Genipap pulp and siriguela seed ethanol extracts presented an AChE inhibition zone similar to that of the positive control, carbachol. AChE inhibition assay with chlorogenic acid, one of the main constituents of siriguela seeds, revealed that this acid showed activity similar to that of the control physostigmine. These data suggest that these extracts are potentially important antioxidant supplements for the everyday human diet, pharmaceutical and cosmetic industries. (C) 2012 Elsevier B.V.
