Abstract:
... Molecular identification is a fundamental issue in astrobiology to investigate the routes of emergence of life on our planet involving in particular a potential seeding of extraterrestrial organic matter on the primitive Earth. However, this project encompasses major difficulties due to the low concentration of molecules present in bodies of the Solar System. This work proposes an integrative anal ...

To overcome the issue, we explored the impact of separating board and anti-blocking mechanism (0, 1/4, 1/2, 2/3, 3/4, and 1 type) on maize seeding under different forward speeds (3, 5, 7 km/h) and rotational speeds (260, 400, 530, 740 rpm), where the performance metric ...

Abstract:
... The scientific consensus is that pesticide use maximizes crop yields in the face of pest and disease pressures. Often, the debate then becomes a “so what” question (e.g., a percent or two increase in yield is inconsequential, so why use pesticides at all?). We set out to help give technical and lay audiences an objective and quantitative sense of what it means for pesticides to protect crop yields ...

We studied whether planting and seeding affected vegetation recovery in a dewatered reservoir, and whether effects differed on landforms composed of fine or coarse‐textured sediments. The dewatered reservoir is behind the former Gl ...
