To the Editor: In our report entitled “Treatment of Cooley’s Anemia” (Blood 76:435, 1990), we described a desferrioxamine provocation test in which we measure serum iron and iron binding capacity following an infusion of the chelator. In the report, we failed to state clearly that we do not use standard colorimetric tests to make these measurements. The mild reducing agents used in most colorim...

zinc­ (zn) is an essential micro­nutrient needed by plants, animals and humans. bioavailability of zn to plant root is controlled through sorption process in soils. to evaluate the effect of citric acid on zn sorption,­ a batch experiment was conducted with two soil samples (s1, s2), that differed in their clay and calcium carbonate contents. three levels of citric acid (0,­ 0.5, 1 mm) and twel...

background : agaricus blazei mushrooms are one of the most important edible and therapeutic mushrooms, and they contain minerals, vitamins, and amino acids essential for the human body. this mushroom is used raw, dried, and in the form of pharmaceutical products. one of the most important processes after harvesting is drying in order to enhance the quality and the length of maintenance of the p...

the equilibrium solubility data of co2 in the various aqueous blends of triisopropanolamine (tipa) + monoethanolamine (mea) with the total alkanolamine concentration of 2 mole / dm3 were measured at the temperatures of 30, 40, 50, 60 and 70 oc and co2 partial pressures below 100 kpa. the experiments were done in an atmospheric gas absorption system and the amount of absorbed co2 was measured wi...

Steel foam offers potential advantages over aluminum foams and other metallic foams. The inherent strength of steel combined with the reduced density of foam presents an attractive material with greater strength and modulus than light alloy foams, greatly reduced density relative to solid steel, and efficient energy absorption. However, thus far there have been few reports describing efforts to...

At the present theoretical study, DFT calculations were performed for elucidating thereaction, absorption energy and the quantum molecular descriptors including electronic chemical potential, chemical hardness, Homo, Lumo, band gap energy (Eg) and finding the most active nitrogen-doped graphene sheet (N-G) for absorption H2S, CH4, N2 and CO2 gases. Finally it found that nitrogen-doped gra...

Automobile light weight structural composites are subjected to the various loadings in their service lives. Honeycombs are increasingly used as core structures in automobile light weight structures as energy absorbers. In this paper the energy absorption of honeycomb panels under impact of cylindrical projectile is numerically and experimentally studied. The effect of the core materials and cro...

nanostructures have considerably higher surface areas than their bulk counterparts; thereforesurfaces often play important, sometimes even dominant, roles in the nanostructure properties. thenanocrystalline and nanotubes have low band gaps and high carrier mobility, thus offeringappealing potential as absorption gas. interaction between methanol molecules and carbonnanotube is investigated usin...

------ARSTRACT-----Corn germ protein isolate (CGP[) was partially hydrolyzed with tryp~ sin and pepsin and succinylated at three levels. Various functional and electrophoretic properties of the native and modified protein were determined. Water absorption and foaming properties of COPT were improved by panial hydrolysis with trypsin: emulsifying capacity and nitrogen solubility were reduced~ oi...
