Analysis of Transmission Characteristic of Straight Bevel Gear and Zero Spiral Bevel Gear

open access: yesJixie chuandong, 2018
The finite element model of a pair of straight bevel gears is established,and the simulation is carried out by using the ANSYS/LS-DYNA software to verify the accuracy of the simulation method.

Techniques for subretinal injections in animals

open access: yesVeterinary Ophthalmology, Volume 28, Issue 2, Page 506-518, March 2025.
Abstract Subretinal injections are not commonly performed during clinical treatment of animals but are frequently used in laboratory animal models to assess therapeutic efficacy and safety of gene and cell therapy products. Veterinary ophthalmologists are often employed to perform the injections in the laboratory animal setting, due to knowledge of ...

Gearing [PDF]

open access: yes
Gearing technology in its modern form has a history of only 100 years. However, the earliest form of gearing can probably be traced back to fourth century B.C. Greece. Current gear practice and recent advances in the technology are drawn together.

Establishment of a Purge and Trap Continuous‐Flow Isotope Ratio Mass Spectrometer System for Analysis of Stable Nitrate Isotopes (δ15N and δ18O) in Water Samples by Ti(III) Reduction

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 14, 30 July 2026.
ABSTRACT Rationale Pollution of surface and shallow groundwater by nitrate (NO3−$$ {\mathrm{NO}}_3^{-} $$) is a global concern, resulting in the deterioration of drinking water quality. Stable isotopes of NO3−$$ {\mathrm{NO}}_3^{-} $$ (δ15N and δ18O) can be used to trace its sources and identify prevailing biogeochemical processes.
