{??u=uN+2N?2+?in?u>0in?u=0on??
where ? is a smooth, bounded domain in ? N , N ? 3, and ? > 0 is a small parameter.This ...
Some applications of the natural uranium isotopes238U and 234U in environmental studies
(2009-02-01)
238U is the principal isotope of natural U (99.72% abundance) and is the progenitor of the (4n+2) series of radioelements. The isotope 234U is radiogenic and the decay chain from 238U through 234U proceeds as follows: 238U ...
The dissolved uranium concentration and 234U/238U activity ratio in groundwaters from spas of southeastern Brazil
(2017-01-01)
This paper describes the natural radioactivity due to 238U and 234U in 75 water sources from spas located in 14 municipalities in São Paulo and Minas Gerais states, Brazil. These waters are extensively utilized for drinking ...
The assessment of soils contamination from U-238 and U-234 disequilibria data
(2018-01-01)
Understanding processes involved in the soils formation is important for appropriate assessment of contamination occurring in the superficial horizons. Several tools have been used for such purpose, including the natural ...

Cloning and molecular characterization of Trypanosoma cruzi U2, U4, U5, and U6 small nuclear RNAs
(Instituto Oswaldo Cruz, Ministério da Saúde, 2007-02-01)
Small nuclear RNAs (snRNAs) are important factors in the functioning of eukaryotic cells that form several small complexes with proteins; these ribonucleoprotein particles (U snRNPs) have an essential role in the pre-mRNA ...
