A study of the effect of certain metals on the prevention of nutritional anemia in the rat has been reported in the preceding paper (4). Animals receiving a mixture of manganese, cobalt, nickel, and zinc with iron developed a progressive anemia and died, whereas those receiving the same mixture with iron and copper developed an abnormally high hemoglobin value at the age of 7 to 9 weeks. After ...
Physiological Effects of Mining Contaminants on Algae with Special Reference to Heavy Metal Toxicity
The process of mining affects all the components of environment and ecology. resulting in different types of pollution problems like soil, surface and ground water pollution. Acid Mine Drainage (AMD) and mine spoil dumps may contain an elevated amount of Heavy metals. Physiological effect of heavy metal toxicity on algal species like Chlorella vulgaris, Scenedesmusbijugatus, Oscillatoriaamphibi...
today, the route for economic development in most countries is the same as international open competitive economy. economic institutes well known that supportive public economy belonged on the past and they may compete in the global economy. it is obvious that if they have no competitive potency or not familiar with competition technique, they may be devastated. banking system aims to collect t...
1. Our data indicate that the effectiveness of whole liver in the treatment of nutritional anemia in rats induced by a milk diet is directly proportional to its available iron and copper content. The other constituents in liver are not needed for maximum hemoglobin regeneration on a diet of milk, iron, copper, and manganese. 2. Commercial preparations of liver products with iron or iron and cop...
Fe2O3 and ZnO nanoparticles were synthesized by a fast microwave method. Nanostructures were characterized by X-ray diffraction and scanning electron microscopy. The goal of bio-fortification is to develop plants that have an increased content of bioavailable nutrients in their edible parts. The micronutrients magnesium (Mg), manganese (Mn) and copper (Cu), boron (B) and calcium (Ca) are essen...
in this thesis, structural, electronical, and optical properties of inverse pervskite(ca3pbo) in cubic phase have been investigated.the calculation have been done based on density functional theory and according to generalized gradiant approximate (gga) as correlating potential. in order to calculate the configurations, implementing in the wien2k code have been used from 2013 version. first of ...
we show that when both sources ( lepton flavor violation sources and cp-violating phases) are present, the electric dipole moment of the electron, $d_e$, receives a contribution from the phase of the trilinear $a$-term of staus, $phi_{a_ au}$. for $phi_{a_ au}=pi/2$, the value of $d_e$, depending on the ratios of the lfv mass elements, can range between zero and three orders of magnitude a...
ABSTRACT- The increasing population and the pastures inability to meet food needs in livestock have led to the increase of cultivates forage plants. In order to evaluate the effect of plant growth promoting rhizobacteria (PGPR) and alfalfa (Medicago sativa) extract on the growth and concentration of macronutrient and micronutrient contents of forage sorghum (Sorghum vulgare), an experiment was...
abstract: the potato tuberworm, phthorimaea operculella (zeller), is an important insect pest of potato (solanum tuberosum l.) in the storage and field in most parts of the world especially in tropical and subtropical regions due to its close relationship with the host, high reproductive potential and high economic losses. information on host preference, life table parameters and digestive en...
This study measured excretion of 11 minerals induced by EDTA chelation therapy in 25 adults (aluminum, cadmium, calcium, chromium, copper, iron, lead, magnesium, manganese, mercury, zinc). We administered 20 EDTA infusions (3 g, with magnesium and ascorbate) 1 to 2 weeks apart and measured 24-hr urinary excretions of minerals before treatment and after treatments 1, 10, and 20. A modest supplem...
