Effect of sulphated

Excessively intensive reduction yields sulphidic compounds which remain dissolved in glass and impart to it a brown colour. The refining effect of sulphate is simultaneously suppressed. [Pg.265]

The in vitro and in vivo effects of sulphated PS were also investigated against the pseudorabies virus (Suid HSV-1), the most notable of which is porcine HSV which has a well-documented history of epizootic infections, especially in Europe [105], In vitro experiments revealed that sulphated PS significantly reduced the number of lytic plaques, but in vivo only heparin protected mice against the pseudorabies virus. [Pg.404]

The retarding effect of sulphates has been likewise found in tests with fibrin. 15 g. of moist fibrin, containing 5 g. of dry substance, are put in contact with pep dissolved in 60 c c. of 1.5 per cent HCl, to which has been added increasing quantities of sodium sulphate. After a digestion of two hours at 50 , it is diluted with water, the imdissolved fibrin is collected and weighed, after drying at 100°. [Pg.181]

According to Hanehara and Yamada [360] the adsorption of carboxylate admixtures is influenced by sulphate ions too and is diminishing with SO concentration increasing. In Fig. 6.104 the effect of sulphate ions on the flow surface area at various number of carboxylate groups in a track chain of PC is shown. [Pg.507]

It has been shown previously that free Mg + behaves as an inhibitor of the enzymic reaction for both Isoenzymes with respect to both MgATp2- gpcl PGA which are the two true substrates for the reaction (7,9). The Inhibition patterns observed are complex and suggest that this could provide a means of slowing down the rate of CO2 fixation when the concentration of free Mg2+ exceeds the supply of ATP (9). In this paper we describe the effects of sulphate and nucleotides on the... [Pg.2926]

Effect of Sulphates. Sulphur dioxide comes from combustion of fuels and is identified as one of the most important air pollutants which contribute to the corrosion of metals. In the presence of SO2, corrosion starts at 60 % relative humidity and the rates are considerably higher than in the absence of any contaminate. There is a close relation between the uptake of SO2 and the corrosion rate measured during field exposure over a period and it depends considerably on the acid hydrolysis of SO2 in water and the fast oxidation of SO2 on iron surfaces. The cycle consists of two reactions, the oxidative hydrolysis of iron sulphate and the subsequent acid corrosion of iron [67]. [Pg.14]
