Here we describe a protocol for manufacturing, calibrating, and conducting measurements with soil surface temperature and moisture sensors.

Here, we report the experimental procedures for manufacturing the semiconductor-electrocatalyst device, details of the experimental set-up in the drop capsule and the experimental sequence during free fall. Behavior Eye-Tracking Control to Assess Cognitive Functions in Patients with Amyotrophic Lateral Sclerosis Jürgen Keller1, Martin Gorges1, Helena E. A.

Ludolph1, Dorothée Lulé1 1Department of Neurology, Ulm University, 2Institute of Medical Technology, Brandenburg University of Technology Cottbus-Senftenberg Cognitive deficits are common in about one third of patients with amyotrophic lateral sclerosis, a neurological condition leading to progressive impairments in speech and movement abilities. To conduct cognitive tests in patients unable to speak or write a reliable and easy to administer eye-tracking paradigm was developed.
