25. Promotion of iron nutrition and growth on peanut by Paenibacillus illinoisensis and Bacillus sp. strains in calcareous soil
ABSTRACT This study aimed to explore the effects of two siderophore-producing bacterial strains on iron absorption and plant growth of peanut in calcareous soil. Two siderophore-producing bacterial strains, namely, YZ29 and DZ13, isolated from the rhizosphere soil of peanut, were identified as Paenibacillus illinoisensis and Bacillus sp., respectively. In po

26. Multivariate approach to assess in vitro Fe bioaccessibility in chicken meat
Abstract A 32 factorial design was employed to develop an in vitro digestion method for estimation of Fe bioaccessible fractions in cooked chicken meat. The effects of sample size and the in vitro bioaccessible fractions of this essential element were evaluated. A sample preparation method employing a microwave assisted digestion with dilute nitric acid was

27. Copper Cobalt Magnetic Ceramic Materials Characterization at Terahertz Frequencies
ABSTRACT: This study presents the complex index of refraction and the complex permittivity of a magnetic ceramic material made of copper, cobalt, and iron oxides. The index of refraction and the extinction coefficient of the CuCo-ferrite exhibit an almost frequency independent behavior and were averaged to n = 3.62 ± 0.05 and k = 0.06 ± 0.02, respectively,

28. Dealing with iron metabolism in rice: from breeding for stress tolerance to biofortification
Abstract Iron is a well-known metal. Used by humankind since ancient times in many different ways, this element is present in all living organisms, where, unfortunately, it represents a two-way problem. Being an essential block in the composition of different proteins and metabolic pathways, iron is a vital component for animals and plants. That is why iron

29. Valorization of mining waste from Ouenza iron ore mine (eastern Algeria)
Abstract The present article is devoted to the development of a hematite-poor ore mine in Ouenza, which does not meet the steelmaker's requirements. Significant volumes are stored at the pithead of the mine, and the reserves are estimated at over 100 million tones. This enormous quantity of mining waste occupies an important space and poses a real threat to

30. Evaluation of the technological, nutritional and sensory qualities of bakery products produced with partial substitution of the wheat flour by whole rice flour
Summary The objective of this work was to determine the technological, nutritional and sensory characteristics of bread produced by substituting 25 and 50% of conventional wheat flour by whole rice flour (Oryza sativa L). The final products were evaluated in terms of specific loaf volume, appearance of the central slice, crumb firmness, moisture content, die

32. Heavy Metals in Garra gotyla , Cyprinus carpio and Cyprinion watsoni from the River Panjkora, District, Lower Dir, Khyber Pakhtunkhwa, Pakistan
ABSTRACT This study was conducted in the River Panjkora, Pakistan, in order to assess the level of heavy metals accumulated in the liver, kidneys, gills and muscle tissues of three highly consumed fish species by the local community, Garra gotyla, Cyprinus carpio and Cyprinion watsoni. The heavy metals including manganese (Mn), iron (Fe), chromium (Cr), zinc

33. Effect of Phosphorylation and Copper(II) or Iron(II) Ions Enrichment on Some Physicochemical Properties of Spelt Starch
ABSTRACT: This paper provides an assessment of the effect of saturation of spelt starch and monostarch phosphate with copper or iron ions on selected physicochemical properties of the resulting modified starches. Native and modified spelt starch samples were analyzed for selected mineral element content using Atomic Absorption Spectroscopy (AAS). Thermodynam

35. Assessment of sugarcane harvesting residue effects on soil spectral behavior
ABSTRACT When the harvesting of sugarcane involves a mechanized process, plant residues remain on the soil surface, which makes proximal and remote sensing difficult to monitor. This study aimed to evaluate, under laboratory conditions, differences in the soil spectral behavior of surface layers Quartzipsamment and Hapludox soil classes due to increasing lev

36. Fast Determination of Iron and Zinc in Hair and Human Serum Samples After Alkaline Solubilization by GF AAS
Methods for the development and validation for determination of iron and zinc in human serum and hair samples by graphite furnace atomic absorption spectrometry (GF AAS) were performed. Solubilization was immediate by manual agitation in both samples with a 10 mL volume sample plus deionized water. Optimum pyrolysis and atomization temperatures were obtained
