13. Obstructive urolithiasis in growing-finishing pigs
RESUMO: Urolitíase obstrutiva é uma enfermidade caracterizada pela presença de urólitos no trato urinário, com consequente obstrução das vias de excreção. Este artigo descreve os achados epidemiológicos e clínico-patológicos de 22 surtos de urolitíase em suínos de crescimento e terminação no Sul do Brasil. Os suínos afetados eram machos e cl

14. Organic trace minerals and calcium levels in broilers' diets to 21 days old
ABSTRACT: This study was undertaken to evaluate the effects of dietary calcium levels and supplementation with organic trace minerals selenium, copper, iron, zinc and manganese on performance, tissue deposition and litter mineral concentration. A total of 2,496 one-day-old male Cobb 500 broilers were randomly assigned to a 3 × 4 factorial experimental desig

15. Charge sparsity: An index to quantify cation effects on clay dispersion in soils
ABSTRACT: Few approaches have been developed to measure the isolated effect of exchangeable cations on clay dispersion in soils. In this study, the charge sparsity (CS) index was proposed using the ratio between the cations hydrated ionic radius and valence. The index capacity to measure cation effects on clay dispersion in soils was also evaluated. Three Fe

16. Field Perception of the Boundary Between Soil and Saprolite by Pedologists and its Differentiation Using Mathematical Models
ABSTRACT Saprolite plays a central role into hydrologic and nutrient cycles. Despite that, saprolite research is scattered and uses heterogeneous, sometimes conflicting, methods and concepts. During field work, it is difficult to assign the boundary between soil and saprolite. This paper aimed to identify the subjacent logic that pedologists use to assign to

17. Impact of CPS1 Gene rs7422339 Polymorphism in Argentine Patients With Hyperhomocysteinemia
Abstract Carbamoyl phosphate synthetase 1 (CPS1) is a key gene in the first step of urea cycle and has been correlated with nitric oxide level and vascular smooth muscle activity. A functional single-nucleotide polymorphism C/A at position 4217 in CPS1 (National Center for Biotechnology Information SNP database no. rs7422339, T1405N) was reported to be assoc

18. Granulated and Biosolid Fertilizers on the Quality of Schinus terebinthifolius Raddi Seedlings
ABSTRACT The objectives of this study were to evaluate substrates produced from the peach-palm agroindustry waste and sewage sludge as a source of nutrients for the production of Brazilian Peppertree seedlings (Schinus terebinthifolius Raddi), and to compare the performance of these substrates under various levels of slow release fertilizer for this species.

19. Humic Substances and Chemical Properties of an Acrisol Amended with Vermicomposted Vegetal and Animal Residues
ABSTRACT Vermicomposted vegetal and animal residues are rich in nutrients and humic substances and thus can be applied to the soil as a source of functionalized organic matter (OM) and as an alternative to chemical fertilizers. In Southern Brazil, many animal and vegetal residues are easily accessible. Therefore, this study aimed to evaluate alterations in s

20. Estresse de aculturação e carga alostática entre mulheres imigrantes mexicanas
Objetivos este estudo de caso-controle comparou os níveis de estresse e carga alostática (CA) entre mulheres mexicanas nos EUA ( n = 19) e no México ( n = 40). Método medidas de estresse incluíram a Escala de Estresse Percebido (EEP) e a Escala de Estresse Social das Mulheres Hispânicas (EESMH). Uma medida composta por 8 indicadores de CA (pressão a

21. Edaphic macrofauna in degradation of animal and vegetable residues
Resumo Este estudo objetivou avaliar a capacidade de degradar a matéria orgânica pela macrofauna edáfica (minhocas), a relação carbono/nitrogênio (C/N) e o potencial hidrogeniônico (pH), durante o processo da vermicompostagem em diferentes resíduos orgânicos. Os tratamentos foram constituídos por resíduos orgânicos de origem animal (esterco bovi

22. Nutritional deficiency symptoms of young ‘cedro doce’ plants grown under macronutrient omission
RESUMO O cedro doce [Pochota fendleri (Seem) Alverson & Duarte] é uma espécie florestal nativa da Amazônia e com expressiva importância ecológica e econômica. Conhecer as exigências nutricionais da espécie permite cultivar o cedro doce com práticas de adubação mais eficientes desde a sua fase de muda. Sendo assim, o objetivo desta pesquisa foi ava

23. Adaptation of domestic effluent for agricultural reuse by biological, physical treatment and disinfection by ultraviolet radiation
Resumo O reúso de efluente doméstico é uma alternativa para a agricultura irrigada em situações de reduzida disponibilidade de água. No entanto, como é comum a presença de patógenos em águas residuárias, torna-se necessário um processo de desinfecção previamente à sua utilização. Com o desenvolvimento da pesquisa, avaliou-se a viabilidade sa

24. Calcium particle size and feeding time influence egg shell quality in laying hens
ABSTRACT. An experiment with Leghorn laying hens was undertaken to determine the effect of oyster shell particle size and feeding time on different production variables, calcium retention, plasma calcium content and egg internal and external quality. Two hundred Leghorn layers (40 weeks old old) were allocated in five dietary treatments with four replicates
