If a linear regression is t to log transformed mortalities and the estimate is back transformed according to the formula E e e a systematic bias occurs unless the error distribution is normal and the scale estimate is gauged to normal variance This result is a consequence of the uniqueness theorem for the Laplace transform We determine the systematic bias of minimum L and minimum L esti mation ...
OBJECTIVE To examine the acaricidal effects of the essential oil of Cymbopogon citratus leaf extract (lemongrass) and ethanolic Azadirachta indica leaf extract (neem) against house dust mites Dermatophagoides farinae (D. farinae) and Dermatophagoides pteronyssinus (D. pteronyssinus). METHODS Twenty-five adults mites were placed onto treated filter paper that is soaked with plant extract and b...
The effect of the fungus Metarhizium anisopliae Ma14 strain, D-limonene, and cypermethrin, alone and combined, on the mortality of Rhipicephalus sanguineus Latreille larvae was evaluated. Eight separate groups with 25 tick larvae were inoculated with the fungus, cypermethrin, and D-limonene, and four groups were used as untreated controls. The groups were inoculated with serial dilutions of eac...
n Sub-Saharan Africa, infant, child and maternal mortalities are very high compared to other regions. We estimate a cross-country empirical model of the determinants of those mortalities. We find, similar to other studies, that in addition to per capita GDP, health and education interventions can affect mortalities, however, the effect depends on the mortality rate being modelled. Importantly, ...
