Intercropping mitigates incidence of the oilseed rape insect pest complex

open access: yesPest Management Science, EarlyView.
Intercropping reduces the incidence of the oilseed rape insect pest complex with a significant impact of the direct visual and physical disruption provided by the companion plant. Abstract BACKGROUND Oilseed rape (OSR, Brassica napus) is a major crop requiring numerous phytosanitary treatments.

Can Entropically Unfavorable Topological Hydrogen‐Bonded Networks Form From Tetrakis‐ or Pentakis(4‐Carboxyphenyl)benzene Derivative?

open access: yesSmall, EarlyView.
1,2,3,5‐Tetrakis‐ and 1,2,3,4,5‐pentakis(4‐carboxyphenyl)benzene derivatives (1235CPB and 12345CPB) form H‐bonded networks with sql‐ and cem‐topologies, respectively. Furthermore,1235CPB forms a more complicated cqe‐topological network structure with three types of voids in crystalline states under the same crystallization condition, although the ...

N2O emission from grass-clover swards is largely unaffected by recently fixed N2 [PDF]

open access: yes, 2004
The contribution of biologically fixed dinitrogen (N2) to the nitrous oxide (N2O) production in grasslands is unknown. To assess the contribution of recently fixed N2 as a source of N2O and the transfer of fixed N from clover to companion grass, mixtures

First Assessment of Genetic Damage in the Speckled Cockroach (Nauphoeta cinerea) After Consumption of Lettuce (Lactuca sativa) Cultivated and Commercialized in Northeastern, Brazil

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT This study reports, for the first time, the use of the speckled cockroach Nauphoeta cinerea as a promising bioindicator for genotoxic monitoring. It was validated through control groups (both positive and negative) in addition to testing lettuce (Lactuca sativa ) samples from public street markets consumed by N. cinerea specimens in Pernambuco,

Convergent Interval Confirmation for Three‐Step Discrete Specific Zeroing Neural Dynamics Illustrated With Repetitive Motion Planning of Redundant Manipulators

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Repetitive motion planning (RMP) for redundant manipulators with high convergent precision becomes an intense research topic due to its more degrees of freedom. In this paper, a specific zeroing neural dynamics (SZND) model for the RMP is first set up via zeroing neurodynamics.
