Analysis of Stable Isotopes of Hydrogen to Determine Migrational Source of Silver-Haired Bats (Lasionycteris noctivagans) in Alabama
(2008-08-15)
Signatures of deuterium obtained from claws of 21 silver-haired bats (Lasionycteris noctivagans) were used to estimate the nearest probable pre-migratory location of these bats. For 5 consecutive weekends beginning 28 ...
Analysis of stochastic vector-host epidemic models
(2017-07-25)
In this dissertation, deterministic and stochastic mathematical models are proposed to study vector-host epidemic models with direct transmission. The total population of the host and the vector is divided into different ...
An Analysis of Strain and Substance Use Among Youth
(2006-05-15)
General Strain Theory has been used to test relationships between delinquency and the various types of strains felt by individuals. Although this theory is relatively new, it has been empirically tested in many studies. ...
