1. A Nodal-iterative Technique for Criticality Calculations in Multigroup Neutron Diffusion Models
ABSTRACT In this work, a nodal and iterative technique to evaluate the effective multiplication factor as well as the neutron flux, in multigroup diffusion problems, is presented. An iterative scheme, similar to the source iteration method, is implemented to decouple the system of differential equations which is the fundamental mathematical model. Then, anal

2. GASES DE NITROGÊNIO REATIVO COMO PRECURSORES DO AEROSSOL ATMOSFÉRICO: REAÇÕES DE FORMAÇÃO, PROCESSOS DE CRESCIMENTO E IMPLICAÇÕES AMBIENTAIS
The increased emissions of reactive nitrogen gases from anthropogenic sources to the atmosphere has been pointed out as responsible for triggering a series of environmental problems at the local, regional, and global scale. Among the many consequences associated with the excess of reactive nitrogen in the environment is the increase of atmospheric aerosol fo

3. Omni-Directional Wideband Antenna Array with Solar Cells
Abstract Distributed sensor networks are becoming more and more widespread due to their substantial benefits to our daily lives. These sensors, in most cases, are distributed in nature and even may require mobility. This, in turn, implies omnidirectional collector units to collect the data from various sensors at arbitrary directions. This work summarizes th

4. SOCIOLOGIA SAGRADA
Benzbromarone (BZB) is a drug that has diuretic activity and is used in the gout treatment. Its therapeutic efficiency is decreased by its low water solubility (11.8 mg L-1) and highly hydrophobic aspect (logP 2.7), which are responsible for affecting its intestinal absorption and bioavailability. BZB inclusion complex (IC) aims at increasing the drug solubi

6. The challenge of restoring tropical freshwater ecosystems
Resumo Vivemos um processo mundial crescente de degradação das bases de sustentação da vida. No Brasil esta ameaça se intensifica pela fragilização crescente das estruturas de proteção ambiental. A restauração ecológica é uma alternativa para enfrentar a degradação dos ambientes aquáticos. Ela tem sido empregada em maior escala nas regiões d

8. Nexos de exclusão e desafios de sustentabilidade e saúde em uma periferia urbana no Brasil
A abordagem do nexo urbano corresponde à compreensão e à busca de soluções integradas mediante o reconhecimento das interdependências entre água, energia e alimentos, recursos cuja escassez configura iniquidades em saúde. A hipótese central deste artigo considera que o contexto de escassez corrobora práticas sociais que podem ser sinérgicas ou con

9. O equilíbrio e a estrutura estelar em uma abordagem simples: a Seqüência Principal
Resumo As condições simultâneas de equilíbrio Virial e equilíbrio hidrostático determinam a existência de soluções para os modelos estelares mais simples. Utilizando estes dois conceitos mostramos que é possível caracterizar a estrutura estelar sem recorrer à integração de equações diferenciais, ao menos para obter as propriedades globais. Al

11. Determinación del área de superficie real de electrodos de titanio modificado con platino por voltamperometría cíclica
ABSTRACT The surface area of Ti/TiO2-Pt electrodes (ASr) in contact with 0.010 M HClO4 solutions was determined by Cyclic Voltammetry (CV) and Atomic Force Microscopy (AFM) techniques. The Ti/Pt/TiO2 electrodes with different amounts of electrodeposited Pt (1, 5 and 10 seconds) were polarized up to 1.5 V vs. Ag/AgCl (sat. KCl) and stabilized at the final pot

12. Crop residue harvest for bioenergy production and its implications on soil functioning and plant growth: A review
ABSTRACT: The use of crop residues as a bioenergy feedstock is considered a potential strategy to mitigate greenhouse gas (GHG) emissions. However, indiscriminate harvesting of crop residues can induce deleterious effects on soil functioning, plant growth and other ecosystem services. Here, we have summarized the information available in the literature to id
