Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae)

The Anatomical Record, EarlyView.
Abstract The unique morphologies of the first two cervical vertebrae, the atlas and axis, represent a significant innovation in mammalian evolution. These structures support the weight of the head and enable intricate movements of the head and neck.

Effect of operating conditions on gearbox noise [PDF]

, 1992
Low contact ratio spur gears were tested in the NASA gear noise rig to study the noise radiated from the top of the gearbox. The measured sound power from the gearbox top was obtained from a near field acoustic intensity scan taken at 63 nodes just above

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.

Dynamics of early planetary gear trains [PDF]

A method to analyze the static and dynamic loads in a planetary gear train was developed. A variable-variable mesh stiffness (VVMS) model was used to simulate the external and internal spur gear mesh behavior, and an equivalent conventional gear train ...

Double‐vestibular incision subperiosteal tunnel access (double‐VISTA) with connective tissue graft for treating multiple gingival recessions: 2‐year follow‐up

Clinical Advances in Periodontics, EarlyView.
Abstract Background Gingival recession has a multifactorial etiology, involving various predisposing and precipitating factors. Non‐carious cervical lesions (NCCLs) are often associated with gingival recession and pose challenges due to their complex pathodynamics.

Guided transpositional bone blocks in esthetic zone: Surgical technique and case report

Clinical Advances in Periodontics, EarlyView.
Abstract Background The ultimate objective of implant dentistry is to position the implant in a three‐dimensional, prosthetic‐driven location. This case highlights a guided approach for harvesting and positioning an autogenous bone block to restore a horizontal bone defect in the anterior maxilla.
