Influencia de interrelacao potássio-magnésio na absorcao e translocacao de fósforo em gergelim (Sesamun indicum L.) by Rossi, C

“…The results indicated that the nutrient solution with K/Mg relations in the order 1,51, 3.1; 61, 02 and 6.0 presented decrease in the level of radioactivity in the aerial pat. In the roots the level of radioactivity increased in the order velation K/Mg in the nutrition solution of 60; 31: 6 1,1,51 and 02…”

Activity concentration and transfer factors of natural and artificial radionuclides in the Swedish counties of Uppsala and Jämtland by Pallavicini, Nicola

“…The study was performed in two areas of Sweden respectively with high natural radioactivity background (County of Jämtland), and high 137Cs deposition area deriving from Chernobyl fallout (County of Uppsala. …”

Comparación de métodos radiométricos y colorimétricos en estudios sobre retención y transformación de fosfato en el suelo by FASSBENDER, H.W., Igue, K.

“…The transformation of phosphates was investigated by Chang and Jackson's fractionation technique and the P in the different extractions was determined colorimetrically and by its radioactivity. The retention results obtained with the two methods were almost identical and the correlation coefficient between both was r 0.998. …”

137Cesium i myrsamhällen i Gävleborgs län 24 år efter Tjernobylolyckan by Brandström , Linnea

“…A model was used to estimate the radioactive fall-out in 1986. The 137Cs within the sampling area was estimated at 90 000 Bq/m2 or higher. …”

Vitamin A absorption determined in rats using a plasma isotope ratio method by Green, Michael, Green, Joanne Balmer

“…Blood samples were collected on days 1, 2, 3, 6, 9, and 12, and plasma was analyzed for 3H and 14C; vitamin A absorption was calculated for each sample as (fraction of oral dose/fraction of intravenous dose) × 100. Radioactivity was also measured in feces and urine collected as pools on days 3, 6, 9, and 12 and in liver and remaining carcass on day 12. …”

Comparison of two detection systems to reveal AFLP markers in plants by Cara, Nicolás, Marfil, Carlos Federico, Garcia Lampasona, Sandra Claudia, Masuelli, Ricardo Williams

“…Originally, the visualization of the amplified fragments was done in polyacrylamide gels, followed by silver staining or by developing in an X-ray plate, when radioactivity is used. In the last 14 years, capillary electrophoresis of fluorescently labeled fragments has been gradually replacing gel-based systems. …”

Actividad fito-estrogénica del trébol blanco in vitro e in vivo y su fluctuación en relación a variables climáticas. Estado metabólico y fermentación ruminal by Gil, L.A, Díaz, M.C, Ramírez, J, Mayorga, M.

“…Because this plant is a major protein source for livestock in Latin America, estrogen activity was measured during a one-year cycle, using methods for comparing radioactivity. Estrogen levels rose with rainfall, sunshine and ruminal fermentation, but was unaffected by environmental temperature and grazing In order to determine whether estrogen activity measured in vitro affected animal fertility, several reproductive parameters of the female mouse were measured after feeding the animal clover extracts, either in liquid form or in two injections. …”
