Male sheep (aged 15 months) from a Massey University flock selected for increased fleece weight for 37 years (FW, n = 13) and unselected controls (C, n = 13), were infected with larvae of Haemonchus contortus (n = 4000), Ostertagia circumcincta (n =

In two successive years young sheep (less than 6 months old; n = 80, Year 1; n = 117, Year 2) from a line selected for increased fleece weight for 37 years and an unselected line at Massey University were either treated with an albendazole controlled

For precise localization of the center and determination of the dimensions of the radioactive material within the capsule of brachytherapy sources, we have developed a method based on simultaneous pin-hole autoradiography of two sources. We construct

The influence of tissue and applicator heterogeneities on brachytherapy dose distributions is not well understood, despite widespread use of shielded applicators in intracavitary therapy. Heterogeneity correction factors (HCF) have been measured usin

Currently-available brachytherapy dose computation algorithms ignore heterogeneities such as tissue-air interfaces, shielded gynecological colpostats, and tissue-composition variations in 125I implants despite dose computation errors as large as 40%.
