(Texas A&M University. Libraries, 1976)Stable carbon isotope fractionations by seventeen species of marine phytoplankton, representing the classes of Bacillariophyceae, Chlorophyceae, Prasinophyceae, Chrysophyceae, Haptophyceae and Dinophyceae, have been ...
-
(Texas A&M University. Libraries, 1972)A general radiocarbon survey was conducted for the Gulf of Mexico and adjacent areas. A wide variety of samples was run in an effort to determine current levels of radiocarbon activity in Gulf coast rivers, the atmosphere, ...

(Texas A&M University. Libraries, 1984)Human prostate cancer has a 17% incidence in men over 55 years of age, with only a 55% survival rate after 5 years of treatment. Presently, no diagnostic procedure is very effective in detecting the early stages of prostatic ...

(PLOS, 2014-03-27)Dispersal is a critical life history behavior for mosquitoes and is important for the spread of mosquito-borne disease. We implemented the first stable isotope mark-capture study to measure mosquito dispersal, focusing on ...
-
(Texas A&M University. Libraries, 1976)The kinetics of formation and isotopic composition of methane generated by pyrolysis at 500°C from coal samples of different ranks, crude oil fractions and some pure organic compounds have been used to study the mechanisms ...
-
(Texas A&M University. Libraries, 1981)Solvent and β-secondary kinetic isotope effects were used to study the hydrolysis mechanisms of some carboxylic anhydrides and a thiolester. The studies were carried out in order to obtain model system data useful in ...
-
(Texas A&M University. Libraries, 1986)The isotope shifts and hyperfine structure splittings of nine stable xenon isotopes in the mass range from 124 to 136 have been measured using the electronic transition 5d⁴D[subscript 7/2] - 6p⁴P⁰ [subscript 5/2] in the ...
-
(2018-08-06)The early Colonial Period visita mission cemetery Tipu represents an important opportunity to understand the role mobility played in indigenous Maya resistance on the southeastern Maya-Spanish frontier. This dissertation ...
