1. Thermophysical and Transport Properties of the BaCl2-CsCl High Temperature Ionic Liquid Mixtures
High temperature ionic liquids (HTILs) densities and transport properties for mixtures BaCl2 CsCl, x(BaCl2) = 0-1, have been studied as a function of composition and temperature. In terms of Arrhenius theory, the temperature correlation of all measured properties was made and discussed. Thermodynamic properties (isothermal compressibility, molecular volume,

2. ADSORPTION OF ATRAZINE IN RICE HUSK BIOCHARS: A PHENOMENOLOGICAL MODEL APPLIED TO EQUILIBRIUM AND KINETIC STUDIES
ABSTRACT Atrazine is an herbicide used to remove weeds in agricultural crops; however, because it is considered toxic, options for removing it from the environment are needed. Adsorption on biochar is an efficient technique for removing organic contaminants. In this study, the atrazine adsorption capacities of two biochars (BCA400 and BCA700) produced from r

3. Interaction of Pb, Ni and Cd with Aquatic Humic Substances of Amazonian Blackwater Rivers
In this study, the extraction and characterization of aquatic humic substances (AHS) from two blackwater rivers in the Amazon basin was carried out in order to assess the seasonal effects in the AHS structure. In addition, an investigation of the complexing capacities (CC) of the structures containing the metal ions CdII, NiII and PbII was also done. The cha

4. Gas exchange, root hydraulic conductivity, water use efficiency and the growth of Toona ciliata clones and seedlings
Resumo As plantações florestais estabelecidas com mudas apresentam heterogeneidade e dificuldades de manejo. Assim, uma alternativa a estes obstáculos é o uso de clones com alta produtividade. Além disso, as plantas clonais diferem das plantas seminíferas na estrutura do sistema radicular, o que pode influenciar a eficiência na absorção de água e d

7. GROWTH AND PHOTOSYNTHETIC EFFICIENCY OF Atriplex nummularia UNDER DIFFERENT SOIL MOISTURE AND SALINE TAILINGS
RESUMO O descarte do rejeito dos dessanilizadores é um problema crescente sobretudo nas regiões semiáridas, sendo necessário o estudo de plantas halófitas como a Atriplex nummularia para o reuso dessas águas salinas. Dessa forma, objetivou-se avaliar o efeito da interação entre níveis de teor de água solo e de salinidade da água de irrigação, na

8. Brachionus rotundiformis Tschugunoff, 1921 from the Brachionus plicatilis species complex (Rotifera: Monogononta): A new record from Galápagos Archipelago, Ecuador
Abstract The presence of the rotifer species Brachionus rotundiformis from the B. plicatilis species complex in Lake Arcturo, a saline lake in the Genovesa Island of the Galápagos Islands, is here reported. This is the first record of the species for the rotifer fauna of Ecuador as well as of the species complex to the Galápagos Islands. This finding is co

10. Fat mass is negatively associated with the physiological ability of tissue to consume oxygen
Abstract Aims: To describe the relationship between variables related to body composition and peak oxygen uptake ( V ˙ O 2peak) and to verify whether fat mass can affect these relationships. Methods: Eighty participants underwent cardiopulmonary exercise testing to measure V ˙ O 2peak and a body composition assessment to measure fat mass, fat fr

11. Potassium Dynamics in Ruzigrass Rhizosphere
ABSTRACT: Ruzigrass (Urochola ruziziensis) has a large capacity to take up K from the soil, including non-exchangeable forms, and can play an important role in nutrient cycling in integrated production systems. However, K transport to roots of brachiarias is not well known, nor the nutrient dynamics in the rhizosphere, where a concentration gradient may be e

12. Root canal preparation using micro-computed tomography analysis: a literature review
Abstract: This literature review has critically analyzed the published research related to the biomechanical preparation of root canals with three-dimensional analysis using micro-computed tomography (micro-CT). In December 2017, six databases (PubMed, Cochrane, Web of Science, Embase, Scopus, and Science Direct) were accessed using keywords to find articles
