DOI: 10.1007/s12524-018-0926-4
Abstract: Spectral screening can play an important role in successful detection of viroid-infected oil palm seedlings from nursery stage prior to transplanting into the field. Coconut cadang–cadang viroid (CCCVd) is the main causal agent of orange… read more here.

DOI: 10.1093/mnras/staa2364
Abstract: Pulsar wind nebulae (PWNe) are the synchrotron bubbles inflated by the rotational energy of a neutron star. Observing variability within them has previously been limited to cases of significant brightening, or the few instances where… read more here.

Narrow, intrinsic C iv absorption in quasars as it relates to outflows, orientation, and radio properties
Sign Up to like & getrecommendations! Published in 2019 at "Monthly Notices of the Royal Astronomical Society"
DOI: 10.1093/mnras/stz2111
Abstract: This work provides evidence that a large fraction of C iv narrow absorption lines (NALs) seen along the line of sight to distant quasars are due to accretion disc winds, while also seeking to understand the… read more here.

DOI: 10.3389/fpls.2022.913240
Abstract: Rapid and non-destructive estimation of leaf nitrogen accumulation (LNA) is essential to field nitrogen management. Currently, many vegetation indices have been used for indicating nitrogen status. Few studies systematically analyzed the performance of vegetation indices… read more here.
