in a greenhouse experiment, the effects of glomus intraradices and indigenous mycorrhizal isolates from soils under plow and no-till treatments on the uptake of 32p placed at 1, 2.5 and 4 cm from the roots of white clover (trifolium repens) in 23, 37 or 46 days after planting were compared.spores of the indigenous fungi were mostly a mixture of glomus mossea, g. clarum, g. caledonium and g....

Small streams in urbanized rural areas receive loads of P from various, often episodic, sources. This paper addresses, through a tracer test with 32P, retention and transport pulse input phosphorus 2.6 km long stretch channelized second-order lowland stream. Tritiated water was introduced alongside the 32P-labelled ortophosphate order to isolate influence hydrodynamic factors on behavior. Trace...

Background: In this study, Quantitative 32P bremsstrahlung planar and SPECT imaging and consequent dose assessment were carried out as a comprehensive phantom study to define an appropriate method for accurate Dosimetry in clinical practice. Materials and Methods: CT, planar and SPECT bremsstrahlung images of Jaszczak phantom containing a known activity of 32P were acquired. In addition, Phanto...

background: recently, different investigators have studied the possibility of radiation therapy in restenosis prevention and have shown promising results. in this study a unique radioactive source for intra vascular brachytherapy (ivbt) was investigated. the two-dimensional dose distribution in water for a 32p ivbt stent has been calculated. the pure beta emitter source 32p has been coated on p...

ADP3and ADPMg caused mixed inhibition of purified yeast hexokinase isoenzymes and ascites tumor hexokinases I and II when ATPMg is the varied substrate. Since exchange between ADPMg and ATPMg is observed under steady state conditions in which free glucose-6-P is not available for reaction, the effect of ADPMg on V,,, must result from its reaction at the ADP product site of the enzyme. glucose-6...
