Assessing the deposition and canopy penetration of nozzles with different spray qualities in an oat (Avena sativa L.) canopy

TL;DR: Results showed that droplet number densities were inversely related to the droplet size produced by the nozzles, yet coverage was increased more by application volume rate thandroplet size.
Journal ArticleDOI

Rural-Urban Differences in Cardiovascular Mortality in the US, 1999-2017.

TL;DR: In this paper, the authors examined temporal trends in cardiovascular disease age-adjusted mortality rates overall and across subgroups stratified by rural-urban area designation in the US using data from the US Centers for Disease Control and Prevention WONDER database.
Journal ArticleDOI

A comprehensive evaluation of the genetic architecture of sudden cardiac arrest.

Foram N. Ashar, +65 more
TL;DR: In this article, a large genome-wide association study (GWAS) for sudden cardiac arrest (SCA) was carried out to examine common variation genomewide and in candidate arrhythmia genes, and the results showed that a comprehensive approach to the genetic architecture of SCA can shed light on the determinants of a complex lifethreatening condition with multiple influencing factors in the general population.
Journal ArticleDOI

Spray deposition on plant surfaces: a modelling approach

TL;DR: A plant architectural model that enables the location of various plant components in 3-D space combined with a particle trajectory model has been used to study the interception of spray droplets by various vegetative elements.
