The Epidemiology, Aetiology, and Histopathology of Developmental Enamel Defects in Human Teeth [PDF]

open access: yes, 1983
PhDThe prevalence of developmental enamel defects in t11 permanent dentition was investigated in a sample of 2923 East London schoolchildren aged 5 to 15 years. Enamel discolourations and hypoplasias were identified using well defined criteria.

Environmental distribution of Bathonian (Middle Jurassic) neoselachians in southern England [PDF]

open access: yes, 2004
Within the Bathonian (Middle Jurassic) a wide range of depositional environments were present across Britain. Within this dominantly carbonate shelf setting, there is a general palaeoenvironmental transition from open marine shelf in the south of England,

Truss optimization with natural frequency constraints using generalized normal distribution optimization

open access: yes, 2022
The newly proposed Generalized Normal Distribution Optimization (GNDO) algorithm is used to design the truss structures with optimal weight. All trusses optimized have frequency constraints, which make them very challenging optimization problems. A large
