HELIOSEISMOLOGY OF PRE-EMERGING ACTIVE REGIONS. III. STATISTICAL ANALYSIS [PDF]

The Astrophysical Journal, 2014
The subsurface properties of active regions prior to their appearance at the solar surface may shed light on the process of active region formation. Helioseismic holography has been applied to samples taken from two populations of regions on the Sun (pre-emergence and without emergence), each sample having over 100 members, that were selected to ...

Seletividade de clomazone isolado ou em mistura para a cultura do algodoeiro Selectivity of clomazone applied alone or in tank mixtures to cotton

Planta Daninha, 2011
O clomazone destaca-se como um dos principais herbicidas utilizados em pré-emergência na cultura do algodoeiro, mesmo levando-se em conta o fato de que muito pouco se sabe em relação à sua seletividade para a cultura.

Emergence of the primordial pre-60S from the 90S pre-ribosome

Cell Reports, 2022
Summary: Synthesis of ribosomes begins in the nucleolus with formation of the 90S pre-ribosome, during which the pre-40S and pre-60S pathways diverge by pre-rRNA cleavage.

Enhancing the weed control efficacy of two pre-emergence herbicides in maize/jack bean and maize/groundnut intercrops in derived savanna [PDF]

Journal of Agricultural Sciences (Belgrade), 2021
The inability of pre-emergence herbicides alone to give season-long weed control in maize production justifies the need for supplementary weed control. Field trials were conducted to evaluate intercropped groundnut and jack bean for enhanced weed control
