1. Limnological layers improve species distribution modeling of aquatic macrophytes at fine-spatial resolution
ABSTRACT Species distribution modeling (SDM) studies of aquatic macrophytes are still attached to methodological paradigms focused on terrestrial plants, such as the use of bioclimatic layers. Our goal was to evaluate the applicability of this paradigm based on a SDM study of Egeria densa, Pontederia crassipes, and Salvinia auriculata in the São Francisco r

2. CONTEMPORARY AND FUTURE POTENTIAL GEOGRAPHIC DISTRIBUTION OF Cedrela fissilis Vell. UNDER CLIMATE CHANGE SCENARIOS
RESUMO O objetivo do presente trabalho foi modelar o nicho climático de Cedrela fissilis Vell. e realizar a projeção espacial potencial contemporânea e futura, considerando diferentes cenários de mudanças climáticas. Os dados de ocorrência da espécie foram obtidos a partir do banco de dados do SpeciesLink e GBIF. Os dados de altitude e 19 variáveis

3. Zoning for edaphoclimatic aptitude of Bambusa vulgaris and Dendrocalamus giganteus in Brazil
RESUMO O uso de materiais renováveis e processos mais sustentáveis são essenciais para minimizar os impactos negativos do crescimento populacional. O bambu é uma alternativa viável, porque é um produto com propriedades potenciais de substituição à madeira. No entanto, para obter um bom rendimento, é necessário identificar locais adequados para a s

4. Modelagem e propriedades termodinâmicas da secagem de fatias de acuri
Resumo O acuri é uma fruta pouco explorada industrialmente, mas com grandes perspectivas e possibilidades de uso. Para tanto, torna-se necessário reduzir o seu teor de água, aumentando então a sua vida útil, o que possibilitará sua utilização em mercados distantes dos locais de produção. Nesse sentido, objetivou-se secar fatias de acuri, com espes

5. Thermodynamic bounds for existence of normal shock in compressible fluid flow in pipes
Abstract The present paper is concerned with the thermodynamic theory of the normal shock in compressible fluid flow in pipes, in the lights of the pioneering works of Lord Rayleigh and G. Fanno. The theory of normal shock in pipes is currently presented in terms of the Rayleigh and Fanno curves, which are shown to cross each other in two points, one corresp

6. The Extended Log-Logistic Distribution: Properties and Application
Abstract We propose a new four-parameter lifetime model, called the extended log-logistic distribution, to generalize the two-parameter log-logistic model. The new model is quite flexible to analyze positive data. We provide some mathematical properties including explicit expressions for the ordinary and incomplete moments, probability weighted moments, mean

7. Importância da força de cisalhamento no padrão de distribuição espacial do invasor Limnoperna fortunei na Bacia do Alto rio Paraná. - Uma avaliação com base em Modelos de Distribuição Espacial
A introdução do mexilhão dourado, Limnoperna fortunei(Dunker, 1857) na América do Sul esteve relacionada ès descargas de água de lastro, com seu primeiro registro em 1991, no estuário do rio da Prata. Desde então a espécie vai adentrando o continente - com várias consequências negativas em âmbitos econômicos e ecológicos. Objetivo: modelar em

8. Potentiometric Titration and Out-Of-Equilibrium pH Response of the Biotite‑Water System
Minerals in soils contribute significantly to the capacity of soils to buffer pH disturbance. In this paper, we present the pH buffering capacity of a common soil phyllosilicate mineral, biotite. We performed equilibrium potentiometric titrations and we also monitored the pH response kinetics of the mineral-water system in order to develop an out-of-equilibr

9. Climate and land-use changes effects on the distribution of a regional endemism: Melanophryniscus sanmartini (Amphibia, Bufonidae)
ABSTRACT Amphibians are the most threatened vertebrate group according to the IUCN. Land-use and land cover change (LULCC) and climate change (CC) are two of the main factors related to declining amphibian populations. Given the vulnerability of threatened and rare species, the study of their response to these impacts is a conservation priority. The aim of t

10. Removal of the synthetic dye Remazol Brilliant Blue R from textile industry wastewaters by biosorption on the macrophyte Salvinia natans
Batch experiments were carried out for biosorption of Remazol Brilliant Blue R dye onto the macrophyte Salvinia natans. Effects of parameters such as initial dye concentration, pH, biosorbent dosage, contact time and temperature were investigated. Chemical and morphological characteristics of the biosorbent were evaluated before and after the biosorption pro

11. Early detection of metabolic and energy disorders by thermal time series stochastic complexity analysis
Maintenance of thermal homeostasis in rats fed a high-fat diet (HFD) is associated with changes in their thermal balance. The thermodynamic relationship between heat dissipation and energy storage is altered by the ingestion of high-energy diet content. Observation of thermal registers of core temperature behavior, in humans and rodents, permits identificati

12. Predicting the geographic distribution of Lutzomyia longipalpis (Diptera: Psychodidae) and visceral leishmaniasis in the state of Mato Grosso do Sul, Brazil
To understand the geographic distribution of visceral leishmaniasis (VL) in the state of Mato Grosso do Sul (MS), Brazil, both the climatic niches of Lutzomyia longipalpis and VL cases were analysed. Distributional data were obtained from 55 of the 79 counties of MS between 2003-2012. Ecological niche models (ENM) of Lu. longipalpis and VL cases were produce
