“…Synthetic Aperture Radar (SAR) imagery is highly suitable for detecting lowland rice, especially in tropical and subtropical regions, where pervasive cloud cover in the rainy seasons precludes the use of optical imagery. Here, we present a simple, robust, rule-based classification for mapping rice area with regularly acquired, multi-temporal, X-band, HH-polarized SAR imagery and site-specific parameters for classification. …”

Use of an antigen trapping elisa kit for field diagnosis of trypanosoma evansi infections in dromedary camels (camelus dromedarius). by Waithanji, Elizabeth M.

“…Fifty microlitres of serum were used per well in the antigen trapping microplate-ELISA, while 10 - 20,LLI were used in antibody ELISA. An optical density greater than twice that of the negative control serum was regarded as positive in the case of microplate ELISA. …”

Crop nitrogen status of early- and late-sown maize at different plant densities by Maltese, Nicolás, Maddonni, Gustavo Angel, Melchiori, Ricardo Jose, Ferreyra, Juan Matías, Caviglia, Octavio

“…Crop N status can be estimated by N nutrition index (NNI), which is based on actual and critical N concentration in crop biomass. Optical measurements of N concentration (e.g. SPAD readings) of the leaf blade subtending primary ear have also been used as a proxy of crop N status. …”
