Mathematical Model of Manufacturing a Novel Type of Hourglass Worm with Circular Tooth Profiles
, 2010 A novel type of hourglass worm is considered, whose surface is formed by the locus of a circular blade. The worm has circular tooth profiles, which are relatively plain.

The Anatomical Record, Volume 309, Issue 7, Page 1713-1748, July 2026.Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.

Structural Concrete, Volume 27, Issue 3, Page 3018-3040, June 2026.Abstract Reinforced concrete (RC) beams can be subjected to torsion, and failure due to torsion is brittle and poses a significant risk to occupants. Moreover, strengthening of existing RC beams in torsion may be required due to the upgrade of the structures or as part of structural rehabilitation.

Wild pig habitat use impacted by prescribed fire in the William B. Bankhead National Forest, USA
The Journal of Wildlife Management, Volume 90, Issue 4, May 2026.Natural resource management activities like integrated wild pig control programs and 3–5‐year interval prescribed burning can reduce wild pig activity and habitat but can have an unintended side effect of allowing them to thrive in sensitive and protected areas, where access and tools are restricted.

Finite element modelling and load share analysis for involute worm gears with localised tooth contact [PDF]
, 2001 A new approach has been developed by the authors to estimate the load share of worm gear drives, and to calculate the instantaneous tooth meshing stiffness and loaded transmission errors. In the approach, the finite element (FE) modelling is based on the

Keeping track of worm trackers [PDF]
, 2013 C. elegans is used extensively as a model system in the neurosciences due to its well defined nervous system. However, the seeming simplicity of this nervous system in anatomical structure and neuronal connectivity, at least compared to higher animals ...

Papers in Palaeontology, Volume 12, Issue 3, May/June 2026.Abstract Dysalotosaurus lettowvorbecki (Ornithopoda, Dinosauria) is a small‐sized dryosaurid iguanodontian known from various isolated remains collected from the Tendaguru Formation (Upper Jurassic, Tanzania). Micro‐computed tomography of a small individual encased in a block offered a unique opportunity to describe c.

Research on a Generating Method of Spiral Flutes of Hourglass Worm Gear Hob
, 2017 All of the cutting edges on an hourglass worm gear hob have different shapes and spiral angles. If the spiral angles are small, straight flutes are usually adopted. But for the hob with multiple threads, the absolute values of the negative rake angles at
