Recent Investigations Nematodes
Three experiments on the control of nematodes in sugarcane fields are described and res+ults based on yield responses and nematode numbers are quoted. Meloidogyne practically disappeared when the grass, Erugrostis curvula was grown for three seasons, but increased when tomatoes and beans were groyn. Yield responses to nematocides in the absence of Meloidogyne show that this is not the only nema...
متن کاملDiving fatality investigations: recent changes.
Modifications to the investigation procedures in diving fatalities have been incorporated into the data acquisition by diving accident investigators. The most germane proposal for investigators assessing diving fatalities is to delay the drawing of conclusions until all relevant diving information is known. This includes: the accumulation and integration of the pathological data; the access to ...
متن کاملRecent Investigations of Psychotropic Compounds
tetrachloride in T H F produces blue-green crystals that are stable to water and to aqueous acid or alkali. The compound can be sublimed or recrystallized from benzene or toluene. The compound is pyrophoric but controlled air oxidation yields uranium oxides and cyclooctatetraene. Mass spectral analysis gives a parent peak for U(CeH& and the fragmentation pattern indicates a ferrocene-like sandw...
