the ingested nitrates sourced from tap water, food, chemicals and pharmaceuticals areconverted to nitrites in the body surfaces by bacteria and then, the nitrite ions can lead thestructural changing in hemoglobin. in the present work, aggregation of the purified hemoglobinin adult (hba) and in fetus or newborn (hbf) in the presence of nitrite ions were studied.hemoglobin aggregation was perform...

Furazolidone, on complexing with DNA, led to its thermal stabilization. The increase in transition temperature of DNA (delta Tm) increased linearly with % A--T content. Increasing concentration of Cu(II) ions progressively lowered the transition temperature of DNA, but Cu(II) ions were not equally effective in lowering the transition temperature of furazolidone-DNA complex. When equimolar amoun...

This study analyzes how Enterprise Content Management systems (ECMs), which manage enterprise knowledge directly correlated with learning in organizational memory, help generate such value by investigating the extent to which developing such technologies actually contributes to improving the efficacy and efficiency of the decision-making processes. For the analysis of the case study we used the...

Lu3+/Yb3+ and Lu3+/Er3+ Co-doped Sb2Se3 nanomaterials were synthesized by a Co-reduction method in hydrothermal condition. Powder XRD patterns indicate that the LnxLn′xSb2-2xSe3 Ln: Lu3+/Yb3+ and Lu3+/Er3+ crystals (x= 0.00-0.04) are isostructural with Sb2Se3. The cell parameters were increased for compounds upon increasing the dopant content (x). SEM and TEM images show that Co-doping of Lu3+/...

Chlorella autotrophica (Clone 580) grows over the external salinity range of 1 to 400% artificial sea water (ASW), can photosynthesize over the range from 1 to 600% ASW, and survives the complete evaporation of seawater. The alga grown at high salinities shows an increase in cell volume and a small decrease in cell water content. Measurements of ion content were made by neutron activation analy...

The polyamine content of isolated E. coli ribosomes is dependent on the nature and concentration of the ions in the medium used for their preparation. When ribosomes are suspended in medium containing amines, the external amines are taken up by the ribosomes. When large amounts of amines are taken up by the ribosomes, part of the original ribosomal amines are displaced into the medium. Magnesiu...

lu3+/yb3+ and lu3+/er3+ co-doped sb2se3 nanomaterials were synthesized by a co-reduction method in hydrothermal condition. powder xrd patterns indicate that the lnxln′xsb2-2xse3 ln: lu3+/yb3+ and lu3+/er3+ crystals (x= 0.00-0.04) are isostructural with sb2se3. the cell parameters were increased for compounds upon increasing the dopant content (x). sem and tem images show that co-doping of lu3+/...

The effect of heavy metals and light metals ions on anaerobic digestion of three agricultural biomasses (two row barley, wheat bran and a mixture of 75 % corn kernels and 25 % corncobs) was investigated in this study. The raw materials were characterized from physico-chemical point of view and their heavy metals content (copper, chromium, nickel, lead and zinc) and light metals ions content (po...

nanoparticles of mn0.5zn0.5-xcdxfe2o4 with x varying from x = 0.0 to 0.3 were prepared by wet chemical co-precipitation method. the structural and magnetic properties were studied by using x-ray diffraction (xrd), scanning electron microscope (sem), transmission electron microscopy (tem) and electron paramagnetic resonance (epr) technique. the lattice constant increases with increase in cd cont...
