13. Broiler Pre-Slaughter Water Diet with Grass Lemongrass (Cymbopogon Citratus Stapf)
ABSTRACT The pre-slaughter management is one of the predisposing factors to the reduction in the quality of the carcass and broiler meat, mainly for being a stressful condition. This study evaluates the inclusion of lemongrass (Cymbopogon citratus Stapf) in the water used in the diet of pre-slaughter broilers for the first time. The carcass and meat quality

14. Nonylphenol: Properties, legislation, toxicity and determination
ABSTRACT This paper aims to gather and discuss important information about nonylphenol, such as physical chemistry properties, toxicity and analytical methods in various matrices. As a degradation product of ethoxylated alkylphenols, nonylphenol presents a higher degree of reactivity than its precursor. Due to its harmful effects on the environment, use and

15. Physical and chemical quality, biodiversity, and thermodynamic prediction of adhesion of bacterial isolates from a water purification system: a case study
ABSTRACT The objective of this study was to evaluate the quality of water purification system and identify the bacteria this system, predict bacterial adherence according to the hydrophobicity of these microorganisms and of the polypropylene distribution loop for purified water. The assessment of drinking water that supplies the purification system allowed g

16. Relationships between Agriculture, Riparian Vegetation, and Surface Water Quality in Watersheds
ABSTRACT Agricultural land use and degradation of natural vegetation in riparian zones can impair water quality. This study was conducted in seven agricultural watersheds in Ibirubá, RS, Brazil, with the following objectives: identify relationships between concentrations of soluble phosphorus (Psol) and nitrate (NO−3) in surface water and agricultural use

17. Effect of alfalfa hay on growth performance, carcass characteristics, and meat quality of growing lambs with ad libitum access to total mixed rations
ABSTRACT Forty male Naemi lambs were used to evaluate the effect of total mixed rations (TMR) alone or in combination with supplementation of alfalfa hay offered at different schedules on growth, carcass characteristics, and meat quality. Lambs at the age of three months, with an average weight of 28.85±1.09 kg, were randomly selected and distributed into f

19. EVALUATING ARSENIC AND MANGANESE REMOVAL FROM WATER BY CHLORINE OXIDATION FOLLOWED BY CLARIFICATION
AbstractThis paper investigates the simultaneous removal of arsenic [As(V) or As(III)] and manganese [Mn(II)] from natural waters of low and high turbidity by clarification (with polyaluminum chloride and aluminum sulfate as primary coagulants) associated or not with chlorine pre-oxidation. The results showed that the clarification process exhibited low Mn(I

20. Bone densitometry and calcium serum levels in chickens treated with filtered or unfiltered water
The aim of this study was to evaluate whether the drinking water of the School of Agricultural and Veterinary Sciences, UNESP, Jaboticabal, Brazil, affected bone mineral density and serum calcium levels of 14-, 21-, and 45-day-old broilers. Bone mineral density (BMD) of the tibiae was assessed using optical densitometry radiographic technique and serum calci

21. Águas pluviais para usos não potáveis em escolas municipais: estudo de caso na região da baixada de Jacarepaguá, RJ. / Rainwater for non potable uses in municipal schools: study of case in the region of Baixada de Jacarepaguá- RJ.
Rainwater harvesting does not constitute a new strategy or technology. However, recently it has been proposed in well-developed regions or in development (peri-urban) in response to long periods of dryness, increased demand for water, greater public awareness of urban flooding and its genesis, and increased interest in sustainable construction practices, inc

22. Chlorophenols in tap water from wells and surface sources in Rio de Janeiro, Brazil: method validation and analysis
Two analytical methods were validated for determination of trichlorophenols, tetrachlorophenols and pentachlorophenol in drinking water. Limits of quantification were at least ten times lower than maximum permissible levels set by the Brazilian legislation, which are 200 ng mL-1 for 2,4,6-trichlorophenol and 9 ng mL-1 for pentachlorophenol. Chlorophenol leve
