We have investigated the sorption potential of three sulfonamides (SAs) in six New Zealand dairy farming soils using a modified batch equilibrium method employing 0.005 M CaCl2 as background solution. Both liquid and solid phases were extracted to analyse for the antibiotic concentrations in order to avoid underestimation that may arise a result of photolysis or biotic degradation. The experime...

Keratin was extracted from purified cornified cells of newborn rats in Tris-HCl-buffered 8 M urea containing beta-mercaptoethanol. Microfilaments were assembled in vitro by reducing the ionic strength of buffer and the urea concentration. One millimolar concentration of KCl and NaCl did not affect filament formation, but the same concentration of divalent cations greatly altered this process. C...

BACKGROUND We quantified age-related decreases in the ability of female participants to generate whole leg movements about the hip. METHODS We measured maximum hip strength and hip velocity in 12 young and 12 older healthy women. Both capabilities could help fall prevention by contributing to fast leg movements. We also measured maximum velocities as a function of isotonic load. RESULTS You...

Humic substances are increasingly used as biostimulants in agriculture because of their supposed effects on nutrient uptake and crop yield. The objective this study was to assess the effect fulvic acid (FA) humic (HA) addition with without fertilization (N, P, K, S, Ca) (i) grass yield (Poa trivialis) (ii) composition soil porewater 0.01 M CaCl2 extracts. Therefore, a pot experiment performed u...

I. Of the cases in which a sore was present at the time of examination there were : Sore 1 to 10 days old 10 Positive 5 11 to 20 ? 13 ? 9 21 to 30 ? 44 ? 42 Of the two negative cases one was observed for three months and no symptoms appeared. "NY e have thus abundant evidence that the W. R. is of use in clearing up the diagnosis. More especially is this the case when the sore is clinically a so...

Natural and synthetic particulates in aquatic environments can act as a vector for chiral pharmaceutical drugs. Understanding enantiomer enrichment the particulate phase of water matrices is essential considering enantiospecific effects that drugs have on exposed organisms. Therefore, adsorption cationic fluoxetine propranolol to polyhydroxyalkanoate bioplastic, polyamide microplastic, cellulos...
