Strain Rates in Prestressed Concrete Sleepers and Effects on Cracking Loads
Electronic Journal of Structural Engineering, 2017 Prestressed concrete sleepers (PCSs) play an essential role in structural response and performance of ballasted railway tracks. Due to defects in track or train components, high magnitude dynamic loads may generate at the rail head and transfer to the ...

Maternal Ethnic‐Racial Enculturation: Implications for Social Skill Development in Early Childhood
Infant and Child Development, Volume 35, Issue 4, July/August 2026.ABSTRACT The influence of maternal enculturation on the social skill development of ethnically and racially diverse young children remains understudied. Because social skills reflect culturally situated norms, evaluations of competence may vary depending on which skills are privileged within an evaluative framework.

Numerical investigation of the dynamic compressive behaviour of rock materials at high strain rate [PDF]
, 2013 The dynamic compressive strength of rock materials increases with the strain rate. They are usually obtained by conducting laboratory tests such as split Hopkinson pressure bar (SHPB) test or drop-weight test.

Multiple Roles of Protamine Kinase SRPK1 and Phosphatase PP1γ in Sperm Development
PROTEOMICS, Volume 26, Issue 7, Page 42-56, July 2026.ABSTRACT Protein phosphorylation regulates key events of male germ cell differentiation. In the testis, SRPK1 and PP1γ are involved in protamine phosphorylation and dephosphorylation, respectively, and their deregulation is linked to defective chromatin structure and male infertility.

Dynamic increase factors for progressive collapse analysis of steel structures considering column buckling [PDF]
Progressive or disproportionate collapse of structures may have severe socio-economic consequences. Aiming at buildings that can withstand such events, one solution is to prevent or minimize the propagation of damage that may lead to progressive collapse
