Phosphorus-32 in the Phage Group: radioisotopes as historical tracers of molecular biology [PDF]
The recent historiography of molecular biology features key technologies, instruments and materials, which offer a different view of the field and its turning points than preceding intellectual and institutional histories. Radioisotopes, in this vein, became essential tools in postwar life science research, including molecular biology, and are here ...

Phosphorus acquisition by wheat from organic and inorganic sources labelled with 32P and 33P radioisotopes [PDF]
ABSTRACT: Investment in soil phosphorus (P) capital in the tropics is often constrained by poor availability of mineral fertiliser to small-scale farmers. Consequently, new sustainable agricultural cropping strategies are required to maintain fertility and maximise crop yields.

Characterisation of soil phosphorus forms in the soil-plant system using radioisotopic tracer method [PDF]
Soil incubation and pot experiments were conducted to follow the sorption processes of added phosphorus (P) fertiliser using the radioisotope tracer technique. Increasing doses of P fertiliser (40, 80, 160, 320 mg P/kg soil) were added to Chernozem and Arenosol and incubated for 1, 3, and 13 weeks. After incubation, perennial ryegrass (Lolium perenne L.

Tracers of modern technoscience [PDF]
Together with genes, drugs or standardized laboratory mice, isotopes might well be considered amongst the scientific objects that shaped science, technology, and medicine in the 20th century 1. Isotopes are forms of the same element that differ in the

New approaches to investigating the function of mycelial networks [PDF]
Fungi play a key role in ecosystem nutrient cycles by scavenging, concentrating, translocating and redistributing nitrogen. To quantify and predict fungal nitrogen redistribution, and assess the importance of the integrity of fungal networks in soil for ...

Peaceful atoms in agriculture and food : how the politics of the Cold War shaped agricultural research using isotopes and radiation in post war divided Germany [PDF]
During the Cold War, the super powers advanced nuclear literacy and access to nuclear resources and technology to a first-class power factor. Both national governments and international organizations developed nuclear programs in a variety of areas and ...
