EXTENT OF SIGHT DISTANCE REDUCTIONS CAUSED BY RAINFALL ON SINGLE CARRIAGEWAY ROADS

, 2020
: The paper is aimed at probing the extent of sight distance reductions along a single carriageway road caused rainy conditions. Stopping and passing sight distances were investigated under dry weather, light, moderate and heavy rainy condition. Rainfall

Radial outer retina reflectivity (RORR) sign in LAMP2‐associated retinopathy

Acta Ophthalmologica, EarlyView.
Abstract Purpose To describe the radial outer retina reflectivity (RORR) sign in patients carrying pathogenic variants in the X‐linked lysosome‐associated membrane protein‐2 (LAMP2) gene and to review the histologic characteristics of LAMP2 expression in the human retina.

Genome‐wide association and interaction analysis for proliferative retinopathy in adults with type 2 diabetes born during famine: The DOLCE study in Ukraine

Acta Ophthalmologica, EarlyView.
Abstract Purpose Proliferative diabetic retinopathy (PDR) is one of the leading causes of blindness in working‐age adults. We have previously shown that the risk of PDR is significantly elevated in individuals with intrauterine exposure to famine. However, the genetic mechanisms mediating this association remain unknown.

Review and design policy of sight distance types for the interurban highway system

, 2019
The paper introduces design policies, model developments and the implementation of sight distances (SDs) in the interurban highway network in Israel. The SD types are stopping sight distance (SSD), decision sight distance (DSD), passing sight distance ...

Student understanding of sight distance in geometric design A beginning line of inquiry to characterize student understanding of transportation engineering

, 2009
While many students demonstrate considerable aptitude in manipulating equations and variables within academic environments, research consistently shows that they lack a construct called conceptual understanding, which accounts for their difficulties in ...

Embodied practice in a disembodied time: How the COVID‐19 pandemic shaped direct work with children and young people

Child &Family Social Work, EarlyView.
Abstract The COVID‐19 pandemic and related restrictions imposed in the UK had a significant impact on social work practice with children and young people. As has been widely reported, practitioners were deprived of multisensory information in their assessments and of opportunities to connect with children.

Suitability of the Euler’s Spiral for Roadside Clearance in Order to Provide Stopping Sight Distances

Journal of Transportation Technologies, 2017
The AASHTO’s guideline for geometric design, also known as the green book, requires that the inside of horizontal curves be cleared of obstructions to sight lines in order to provide sufficient sight distances. Recently, innovative use of Euler’s spiral for determination of clearance offsets has been proposed.
