formaldehyde from shaped cellulose acetayte articles containing methylolated melamine or guanamine polymers is reduced by adding to the solutions from which the cellulose acetate article is regenerated, from 1 to 20% by weight based on the weight of the methylolated polymer of a cyclic urea ...
The amounts of the precursors were calculated in such a way to produce a nanocomposite containing 10 wt.% CuFe2O4/(CuFe2O4 + SiO2). A solution containing urea (3.513 g of urea, NH2CONH2 Aldrich, >99%, 9 mL of absolute ethanol, Fisher Chemicals, 4.92 mL of distilled ...
What is the molality of solution containing 200 mg of urea(molar mass60g mol−1)dissolved in 40 g of water ? View Solution In a clinical laborator, a sample of urine containing 0.120 g of ureaNH2CONH2(M.Wt.60. was treated with excess of nitrous acid. The urea reacted according to ...

Presentation: A glass single-use vial containing 0.23 ml solution containing 2.3 mg of ranibizumab (10 mg/ml). Indications: The treatment in adults of neovascular (wet) age-related macular degeneration (AMD), the treatment of visual impairment due to diabetic macular oedema (DMO), or...
PURIFICATION OF UROKINASE PURPOSE:To separate highly pure urokinase in high yield, from a solution containing crude urokinase, by adding a specific amount of urea to the solution, and treating with a strong acidic cation exchange resin having NH4<+>-type sulfonic... Y Hideki,U Yasuo,Y Jiyunic...
The (high pressure) loop comprises synthesis reactor wherein NH3 and CO2 are reacted to produce urea. The effluent leaving the reactor is fed into a first isobaric stripper to produce a first solution containing a strong NH3 excess (NH3:CO2 > 6 by moles) and a low CO2 precentage (CO2:...
E, hydrodynamic radius (Rh) distribution functions for a 50 μM solution of N1 in 20 mM Tris HCl, pH 7.4 (black line) and in a 4 M urea-containing buffer (red line). MBP, maltose-binding protein; TEV, tobacco etch virus. To address the possibility that the GFP tag influences LLPS...
The reaction was developed by adding 50 µl of a solution containing 2 g/l ortho-phenylenediamine and 0.03% H2O2 in 0.1 M citrate–phosphate buffer and was stopped with 50 µl of 4 N H2SO4. The final color was read at 492 nm in an ELISA reader (SLT Lab Instruments). The ...
The cells were grown for another 10 days without changing the medium and then stained with Giemsa solution (Sigma). Colonies containing >50 cells were counted. The number of colonies in the plate receiving γ-irradiation was divided by the number not receiving γ-irradiation and expressed as ...
