Performance of Warranted Asphalt Pavements: Smoothness and Performance of Indiana Warranted Asphalt Pavements

, 2016
In the early 1990s the Indiana Department of Transportation (INDOT) developed a five-year warranty specification for asphalt pavements with the first project being built in 1996. In 2004, results indicated that the asphalt pavements built with the warranty specification had improved performance over the conventional asphalt pavements.

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

PERFORMANCE ENHANCEMENT OF ASPHALT PAVEMENT [PDF]

Al-Azhar Bulletin of Science- Basic Science Sector, 2013
Age hardening of paving grade asphalt is a major factor affecting the durability of bitumen pavement. In this research, 60/70 penetration grade asphalt is modified using Styrene Butadiene Rubber(SBR) in percentages by weight of asphalt ranging from 2 to 6% and 1% by weight of asphalt of an antioxidant namely 4.4.

The hydrological performance of a permeable pavement [PDF]

Urban Water Journal, 2010
Urban stormwater runoff is a transport medium for many contaminants from anthropogenic sources. There are many alternative management strategies available to treat these contaminants. One of the technologies suggested for this purpose is the use of permeable pavements to minimise the quantity of surface runoff generated by impervious surfaces within an

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.
