1. Influence of bottom ash and red mud additions on self-leveling underlayment properties
Abstract Self-levelling underlayments (SLUs) based on Portland cement (PC) are susceptible to cracking due to drying shrinkage. The present study evaluated the influence of binder contents on systems consisting of calcium aluminate cement (CAC), PC, and a source of calcium sulfate (C$), derived from the flue gas desulfurization process (FGD), on the mechanic

3. Effects of exercise on cations/anions in blood serum of English Thoroughbred horses
RESUMO Equinos da raça Puro-Sangue-Inglês são difundidos no México e, devido à falta de dados sobre sua fisiologia do exercício, é importante fazer testes de exercício para obter informações sobre os efeitos do exercício em cátions/ânions mais essenciais no soro do sangue, pois esses equinos são submetidos a esforços constantes. O estudo foi r

5. Coupled monolithic columns as an alternative for the use of viscous ethanol–water mobile phases on chromatographic fingerprinting complex samples
ABSTRACT Concepts of sustainability have received attention from people involved in investigation of nature-derived matrices. The effects of concomitant pollutant activities are cumulative and harmful to the environment from which these matrices are obtained. High performance liquid chromatography analyses generate millions of litters of chemical waste world

6. Tensile Behaviour and Durability Issues of Engineered Cementitious Composites with Rice Husk Ash
ABSTRACT The Engineered Cementitious Composites (ECC) is a special type of High Performance Fibre Reinforced Cementitious Composite (HPFRCC) characterized by a high tensile ductility with a 2% maximum volume of micro fibres. ECC has a tensile strain-hardening performance that leads to multiple cracking behaviour, thus providing the high ductility to the conc

7. Energy evaluation of an evaporative cooling system using water driven ejector
The search for efficient and accessible cooling systems has increased worldwide. This study aims to build and evaluate an evaporative cooling system using a water driven ejector, allowing it to be installed in places with plenty of water. The system was investigated varying the flow rate and temperature of the circulating water, temperature of the replacemen

9. The efficacy of a chitin synthesis inhibitor against field populations of organophosphate-resistant Aedes aegypti in Brazil
The mosquito Aedes aegypti is the main focus of dengue control campaigns. Because of widespread resistance against conventional chemical insecticides, chitin synthesis inhibitors (CSIs) are considered control alternatives. We evaluated the resistance status of four Brazilian Ae. aegypti populations to both the organophosphate temephos and the pyrethroid delt

10. AvaliaÃÃo da Piscicultura em Esgoto DomÃstico Tratado: Aspectos ZootÃcnicos, Ambientais e de Qualidade do Pescado Produzido / Evaluation of treated domestic sewage in fish: aspects of husbandry, environmental and quality of fish produced.
The use of wastewater is an alternative widespread nowadays. One way to reuse it in fish activity, considering that the effluent from Sewage Treatment Stations, are rich sources of nutrients that could be used by fish. However, some restrictions arise regarding the quality of animals for use in human diet. Thus, this research was conducted using treated sewa

12. Study on properties of rice husk ash and its use as cement replacement material
This paper investigates the properties of rice husk ash (RHA) produced by using a ferro-cement furnace. The effect of grinding on the particle size and the surface area was first investigated, then the XRD analysis was conducted to verify the presence of amorphous silica in the ash. Furthermore, the effect of RHA average particle size and percentage on concr
