O FIRESIG atende as demandas específicas de atividades de monitoramento, prevenção e combate a incêndios. Os usuários institucionais do FIRESIG se referem ao Instituto Ambiental do Paraná (IAP) e a Coordenadoria Estadual de Defesa Civil do Paraná. O FIRESIG oferece ferramentas para: (i) entrada de dados de focos de calor, índice de vegetação e índice de risco de incêndio, (ii) espacialização, visualização e análise de focos de calor, (iii) identificação de recursos e infra-estrutura disponível para combate aos incêndios, (iv) atualização da base de dados dos recursos disponíveis para o combate aos incêndios, (v) determinação de melhores rotas de acesso aos incêndios. A utilização do FIRESIG reduz o tempo de resposta para o combate aos incêndios e auxilia a montagem de estratégias de combate. O FIRESIG é caracterizado como um sistema de suporte a tomada de decisão, robusto e de baixo custo para combate aos incêndios. Além do mais pode ser adaptado para ser utilizado em outros tipos de desastres ambientais. FIRESIG – DECISION SUPPORT SYSTEM FOR FIRE FIGHT IN PARANÁ Abstract The FIRESIG represents a decision support system for fire fight in the Paraná State. The FIRESIG meets specific demands for monitoring, prevention and fire fight. The system’s users are the Paraná Environmental Institute and the Paraná Civil Defense Coordination. The FIRESIG offers several tools for: (i) hot spots, vegetation index and fire risk index data input, (ii) mapping, visualization and hot spots analysis, (iii) identification of available resources and infrastructure for fire fight, (iv) data base update, (v) determination of firefight best routes. The use of FIRESIG reduces fire fight response time and helps the fire fight strategy definition. The FIRESIG can be considered as robust and a low price fire fight system. Additionally, the system can be adapted for use as a decision support system for other environmental disasters.

Mutations induced by UVB (313-nm) radiation, a wavelength in the region of peak effectiveness for sunlight-induced skin cancer in humans, have been analyzed at the sequence level in simian cells by using a plasmid shuttle vector (pZ189). We find that significant differences exist between the types of mutations induced by this solar wavelength and those induced by nonsolar UVC (254-nm) radiation. Compared with 254-nm radiation, 313-nm radiation induces more deletions and insertions in the region sequenced. In addition, although the types of base substitutions induced by the two wavelengths are broadly similar (in both cases, the majority of changes occur at G-C base pairs and the G-C to A-T transition is predominant), an analysis of the distribution of these base changes within the supF gene following irradiation at 313 nm reveals additional hot spots for mutation not seen after irradiation at 254 nm. These hot spots are shown to arise predominantly at sites of mutations involving multiple base changes, a class of mutations which arises more frequently at the longer solar wavelength. Lastly, we observed that most of the sites at which mutational hot spots arise after both UVC and UVB irradiation of the shuttle vector are also sites at which mutations arise spontaneously. Thus, a common mechanism may be involved in determining the site specificity of mutations, in which the DNA structure may be a more important determinant than the positions of DNA photoproducts.

Identification of hot spots or protein-target binding sites in proteins using resonant recognition model requires the knowledge of characteristic frequency. For a successful protein target interaction, both the protein and the target signals must share the same characteristic frequency. The common characteristic frequency of a functional group of proteins is determined from the consensus spectrum obtained using DFT. In this work an alternative approach for identification of characteristic frequency using power spectral density is described. The performance of the proposed method is observed to be better than the DFT-based approach and is illustrated using simulation examples.

Abstract. Fatima A, Messaoud R, Takia L. 2019. Relationship between lichen diversity and air quality in urban region in Bourdj Bou Arriridj, Algeria. Biodiversitas 20: 2329-2339. The lichenic biodiversity can be an excellent instrument for measuring air quality biomonitoring in urban and industrial areas. Two bio-monitoring techniques were used to assess and map the levels of air quality in Bordj Bou Arreridj region (BBA), an urban area located in Eastern Algeria, and to identify species sensitive to air pollution. The first one was based on the diversity and abundance of epiphytic lichens, while the other technique was using two bio-indication indices. Epiphytic lichens were sampled from thirty-four stations chosen on the basis of the presence of suitable phorophytes on which it is possible to observe lichens. The assessment of lichen biodiversity was based on the calculation of lichenic abundance indices (LA) and the Shannon index (H'). For the determination of the different levels of air pollution, the indices of atmospheric purity (IAP) and lichen diversity (LDV) were used. There were 62 identified species belong to 19 families and 31 genera of lichens, among which crustacean and foliose thalli were the most common in the region. Lichen biodiversity decreased as the sampled location approaching industrial sources and road traffic. The IAP ranged from 16.19-79.82 and LDV values ranged from 12.50-52.16. The results showed a significant relationship between lichen diversity and air quality, and indicated low atmospheric pollution in the BBA region. This study allowed us to draw up a list of sensitive species and tolerant species to air pollution.
