1. AVALIAÇÃO DE ADITIVOS DE FASE MÓVEL E TEMPERATURA NA VIDA ÚTIL DE COLUNAS PARA CROMATOGRAFIA LÍQUIDA DE ALTA EFICIÊNCIA
Buffered solutions, additives, and column temperature are widely used in high-performance liquid chromatography to promote adequate retention of compounds and to improve the chromatographic separation. However, these factors can dramatically reduce the column lifetime. In this work, the effect of column temperature, pH and the salt type and concentration in

6. Main Variables of Brazilian Public Policies on Biomass use and Energy
ABSTRACT Biomass is an important energy source, since it considers wastes discarded by other productive processes as inputs. As such, the determination of the most relevant variables, within an institutional dimension, exerts a significant influence to point out actions that should receive greater attention for the satisfactory implementation and monitoring

7. Monitoring reinforcement corrosion of concretes designed for nuclear facilitie
ABSTRACT The facilities designed for the peaceful activities of nuclear energy are made with different materials, among them, reinforced concrete. This material, in addition to being structural, is a barrier for isolation and confinement from the environment of the radioactive materials. One of its degradation mechanisms is the corrosion of the reinforcement

8. Comportamiento del residuo de vidrio molido en cementos mezcla: Estudio comparativo con microsilice
ABSTRACT Due their high content of silica in an amorphous state the glass, in theory, can behave as pozzolanic material when are finely ground. This opens up an interesting way of reusing these materials in the Portland cement industry (CP), especially considering that solid urban waste (RSU) in Argentina contains between 3 and 5% by weight of glass. This pa

10. Degradation of sewage sludge compost disposed on the soil
ABSTRACT This study aimed to monitor degradation of compost from undigested sewage sludge disposed on soil surface or incorporated it. The sewage sludge was blended with wood sawdust during a 90-day composting to achieve a C/N ratio of 9. Each waste was dosed based on its total content of nitrogen and on an annual dose of 500 kg ha-1, which is broadly recomm

12. Methane production in anaerobic digestion of organic waste from Recife (Brazil) landfill: evaluation in refuse of diferent ages
This work focuses on monitoring the generation of biogas by biochemical methane potential (BMP) assays, commonly used to assess anaerobic biodegradability of solid and liquid wastes under controlled conditions. The experiment employed 5 g of substrate of both refuses (fresh and one-year-old wastes), digested with 250 mL of inoculum in 1 L flasks as bioreacto
