1. Root morphology and kinetics of Zn absorption by roots of common bean influenced by Zn status of the root environment
ABSTRACT Understanding the kinetics of Zn absorption by roots and its effect on morphology of this organ is relevant for improving crop management, but still poorly studied for common beans. Therefore, an experiment was conducted in a hydroponic system with five initial concentrations of Zn (CZnI): 0.0; 1.0; 4.0; 16.0 and 48.0 µmol L-1. The experiment was i

2. Selected minerals concentration and microbiological safety in non-carcass bovine components of “PANELADA” dish
Abstract “Panelada” is a typical dish from Brazil, made up of some bovine non-carcass components (intestine, rumen and ox feet), whose nutritional value and microbiological quality are not reported. The total contents of selected minerals were determined using flame atomic absorption spectrometry (FAAS) and electrothermal (ETAAS) for samples of raw, seas

3. Effect of drying on nutritional composition, antioxidant capacity and bioactive compounds of fruits co-products
Abstract Fruit coproducts fruit, made of peels, seeds and pulp, discarded during the industrial processing, contain lots of health beneficial compounds, however, high moisture content limits its use. Drying is a low cost and great potential alternative for using. This study aimed to evaluate the phenolic compounds content, in vitro antioxidant capacity and t

4. Physical and chemical characterization of sewage sludge with different proportions of diatomaceous earth
ABSTRACT The use of residues for agricultural production is an alternative for the achievement of sustainability. When mixed with diatomaceous earth (DE) from biofuel filtration, sewage sludge (SS) plays an important role as soil conditioning agent. As a result, the objective of this work was to make a DE vermicompost at different proportions: 0; 7.53; 15.06

5. Millet irrigation with treated wastewater: Gas exchange response and nutrient accumulation
RESUMO As águas residuárias podem ser consideradas como uma fonte hídrica e nutricional excelente para as plantas cultivadas. Porém, a presença de altas concentrações de sais e de compostos tóxicos pode afetar negativamente as plantações. Avaliou-se o efeito da irrigação com diferentes concentrações de água residuária tratada sobre o acumulo

6. The effects of two abundant ant species on soil nutrients and seedling recruitment in Brazilian Atlantic Forest
ABSTRACT Ants can influence soil fertility and the spatial distribution of seeds, with possible effects on seedling recruitment. The ant species Pachycondyla striata Fr. Smith, 1858 and Odontomachus chelifer (Latreille, 1802) co-occur in many forest areas in the Neotropics. We assessed soil fertility and seed bank structure in soil samples close and distant

7. Effect of In Ovo Feeding of L-Glutamine to Chick Embryos
ABSTRACT In ovo feeding (IOF), injecting nutrients into the amnion of the avian embryo may enhance hatchability, gastrointestinal development and serum metabolism changes. This hypothesis was evaluated with 5 IOF solutions containing L-glutamine. Were used 315 fertile Rhode Island Red eggs were used (breeders with 32-weeks). The experimental design was compl

8. Multi-Energy Calibration: A Practical Method for Determination of Macro and Micro Nutrients in Meat by ICP OES
The multi-energy calibration (MEC) was evaluated for the determination of Ca, Cu, Fe, K, Mg, Na, P, S, and Zn in meat samples by inductively coupled plasma optical spectrometry (ICP OES). This calibration method consists of using only two calibration standards and several atomic and ionic emission wavelengths with different sensitivities to determine the ana

9. Ploidy influences on metabolic substrate deposition of rainbow trout
ABSTRACT. Triploid fish are usually sterile. Thus, the energy and nutrients intended for sexual maturation may be available to enhance flesh quality and physical growth. The present study aimed to investigate differences in the metabolic substrates, lipids and proteins, between storage tissues from diploid and triploid female rainbow trout. Monthly, metaboli

10. Response of duck breeders to dietary L-Carnitine supplementation during summer season
Abstract: A total number of 300 (225 ducks and 75 drakes) Sudani ducks, 28-wk-old were divided into five groups to investigate the effects of dietary L-carnitine (LC) supplementation on productive, hatching and physiological performance as well as nutrients digestibility coefficients. The results indicated that the productive performance and Semen quality pa

11. Physico-chemical characteristics of passion fruit flour under removal of flavedo and of maceration
RESUMO O maracujá tem a casca (albedo e flavedo) como componente majoritário, podendo esta, ser utilizada na fabricação de farinha como fonte de nutrientes e para enriquecimento de produtos alimentícios. Assim, objetivou-se neste trabalho estudar o processo de fabricação de farinha do albedo e da casca integral de maracujá nas temperaturas de 70 e 80

12. NONDESTRUCTIVE ESTIMATION OF LEAF NUTRIENT CONCENTRATIONS IN EUCALYPTUS PLANTATIONS
ABSTRACT Determination of leaf nutrient concentrations is traditionally performed by carrying out destructive procedures, requiring laboratory chemical analysis, specialized equipment, and skilled labor. However, technological advances in recent years have now made it possible to analyze leaf nutrient concentrations using non-destructive methods such as leaf
