Functional Analysis of Novel Replication Protein a Homologs in the Euryarchaeota: Implications in the Evolution of Single -Stranded DNA Binding Proteins Across the Three Domains of Life
… in archaea exhibit more similarity to eukaryotic RPAs than to bacterial SSBs. Currently, cultivable archaea are grouped into two subdomains, namely the Crenarchaeota and the Euryarchaeota. While to date the crenarchaeotes have been shown to harbor a single gene encoding a single …

A Framework for Validation and Testing of a CubeSat Retarding Potential Analyzer
Traditionally, Retarding Potential Analyzers (RPAs) operate exclusively on large satellites due to the size, power, and mass constraints posed by nano-satellites like CubeSats. These sensors take in-situ measurements of Earth's atmospheric ion current during a range of time-varied ``retarding" …

Utilizing Remotely Piloted Air Systems in the Delineation of Functional Land Management Zones
… carbon using a remotely piloted air system (RPAS); and 2) develop a method of management zone delineation that accounts for multiple soil functions. Remote sensing was found to be the most effective at estimating soil organic carbon (SOC) through the use of DSM. SOC and topography were found …

Assessment of the spatial variability of vegetative status in vineyards using non-destructive sensors: Application of remote and proximal sensing technologies in precision viticulture
… usefulness of a remotely piloted aerial system (RPAS) multispectral imagery was tested to assess the vegetative growth of a vineyard. A special focus was set on proximal sensing, especially on a fluorescence sensor used either manually and on-the-go, to determine chlorophyll, flavonol and …
