Fig. 6. Analysis of the volatile amines present in Chenopodium vulvaria L. Curve A: standard mixture ofmono-, diand tri-methylamines. Curve B: chromatogram of the amines present in an acid extract ofthe plant, showing the presence of only ammonia and trimethylamine. (Column length, 4ft.; liquid phase, hendecanol-iS% liquid paraffin (v/v); temp., 78 50; flow rate of nitrogen, 5.7 ml./min.; nitro...

the present paper concerns on the selective and very efficient transport of thorium(iv) ions from aqueous solutions through an emulsion liquid membranes composed by paraffin and a surfactant, without carrier requirement. the influence of ph of the external aqueous phase, the surfactant concentration in the membrane phase, the type, and concentration of the acid used in the receiving phase, the ...

conclusions the most effective enhancer for aha and ha were liquid paraffin and glycerol, respectively. the most effective surfactant for both aha and ha was tween 80. the effects of the enhancers were increased by prolonging the exposure time. results after 1.5 and 12 hours, the maximum permeated amount of aha were 89.8 and 342.5 mg, respectively, which related to the formulations with liquid ...

The objective of the present work is to investigate full phase diagram a binary system composed carbon dioxide and heavy paraffin. An alkane with an odd number was chosen since mixtures paraffins crystallize in orthorhombic structure like pure do. normal-heptadecane taken into consideration for this study as it has melting temperature close ambient condition (295 K). consists measuring both flu...

The rash was multidermatomal, with patchy areas of ulceration, crusting, excoriation and necrosis (Figure, A and B). Active bleeding, seborrhoeic discharge and occasional vesicles were also noted, extending to the left pelvis. Subsequently, the patient developed concurrent Pseudomonas aeruginosa cellulitis and bacteraemia. Punch biopsies were non-specific with dermal necrosis, excoriation and p...

or irritation. Next she was given a full and heavy meal consisting of bread and plantains only, and kept under observation. Only solids were enjoined for the first twenty-four hours and a strict watch was kept on all motions passed thereafter. From the 25th evening, she was allowed thick curds and on the following day a little milk also. One ounce of liquid paraffin was given in the forenoon of...
