Tethered satellite control mechanism [PDF]
, 1983 The tethered satellite control mechanisms consist of four major subsystems. The reel drive mechanism stores the tether. It is motor driven and includes a level wind to uniformly feed the tether to the reel.

The Anatomical Record, EarlyView.Osteohistological sampling on different bones of theropod dinosaur documents discrepant age record, growth, and metabolism. This could result unprecise paleobiological inferences if samplings are based on single bones. However, multi‐bone sampling can attenuate these discrepancies, helping to infer growth dynamics and physiology of these extinct ...

Aras Dağları'nın Neotektonik Gelişimi ve Volkanik Jeomorfolojisi (Doğu Anadolu)
Coğrafi Bilimler DergisiThe Aras Mountains are a NW-SE trending volcanic belt of stratovolcanoes in the east of the Eastern Anatolian High Plateau. Kandil, Durak, Dumanlı-Mamzi, Zor and Pamuk Mountains are the main stratovolcanoes along the belt from NW to SE. The morphogenesis

Electrohydrodynamic deformation and rotation of a particle-coated drop
, 2015 A dielectric drop suspended in conducting liquid and subjected to an uniform electric field deforms into an ellipsoid whose major axis is either perpendicular or tilted (due to Quincke rotation effect) relative to the applied field.

Observational constraints on the orbit and location of Planet Nine in the outer solar system [PDF]
, 2016 We use an extensive suite of numerical simulations to constrain the mass and orbit of Planet Nine, the recently proposed perturber in a distant eccentric orbit in the outer solar system.

Commissioning an Inexpensive Off‐The‐Shelf Spectrograph for Radial‐Velocity Studies
Astronomische Nachrichten, EarlyView.ABSTRACT We present a way to set up an inexpensive out of the shelf spectrograph at a local observatory. Stability and resolution of the spectrograph are high enough for radial velocity determination of binary stars or determination of stellar characteristics. Even some exoplanets might be detectable via the radial velocity method.
