INDUSTRIAL RADIATION MONITORING AROUND KADUNA METROPOLIS
Academy Journal of Science and Engineering, 2009 Apart from the amount of radiation, which may be encountered due to radioactive substances, individuals are also exposed to radiation because of the nature of the environment.

Advanced Science, EarlyView.An advanced, long‐term human skin platform maintains native skin structure and key tissue functions for up to four weeks. The platform models chronic inflammation, aging‐related skin changes, and UVB damage, enabling drug and topical interventions—including anti‐inflammatory therapy, senolytic treatment, and sunscreen—to be evaluated in intact human ...

METABOLISM OF RADIOACTIVE β-(3,4-DIHYDROXYPHENYL)-ALANINE-α-C14IN THE ALBINO RAT
, 1955 When DL-3,4-dihydroxyphenylalanine-α-C14(DL-dopa-α-C14) was injected into rats, 80% of the radioactivity was recovered from urine and 2% from respiratory carbon dioxide.

Rhizodeposition Drives One Third of Belowground Carbon Input in Agroecosystems
Advanced Science, EarlyView.This study quantifies photosynthesized C allocation in the plant–soil system across six crop types: barley, wheat, maize, rice, legumes and grasses. It reports C partitioning into shoot respiration, shoot‐C, root‐C, net rhizodeposition and root‐derived CO2, providing standardized percentage averages and GPP‐derived absolute values as a robust baseline ...

Radioautographology: the proposal of a new concept
Brazilian Journal of Medical and Biological Research, 1998 A new concept termed "radioautographology" is advocated. This term was synthesized from "radioautography" and "ology", expressing a new science derived from radioautography.
