Understanding the connections among genotype, phenotype, and fitness through evolutionary time is a central goal of evolutionary genetics. Wrinkly spreader (WS) genotypes evolve repeatedly in model Pseudomonas populations and show substantial morphological and fitness differences. Previous work identified genes contributing to the evolutionary success of WS, in particular the di-guanylate cycla...

The aim of this study was to determine the degradation resistance of three new formulations-silorane-, Ormocer- and dimer-acid-based materials-and compare them to the traditional dimethacrylate-based materials. One silorane- (Filtek P90, P90), one Ormocer- (Ceram-X, CX), one dimer-acid- (N'Durance, ND) and two dimethacrylate-based (Filtek P60, P60; Tetric Ceram, TC) materials were investigated....

In the developing nervous system, axons are guided to their targets by the growth cone. Lamellipodial and filopodial protrusions from the growth cone underlie motility and guidance. Many molecules that control lamellipodia and filopodia formation, actin organization, and axon guidance have been identified, but it remains unclear how these molecules act together to control these events. Experime...

Passive wastewater treatment systems are commonly applied in northern Canadian communities. Pathogen removal in these systems, which relies on natural purification, can be greatly affected by Arctic environmental conditions. In 2012, new Wastewater Systems Effluent Regulations (WSER) were implemented in Canada, but not in the far North due to the number of northern communities with limited wast...

The Water and Sanitation Program is a multi-donor partnership administered by the World Bank to support poor people in obtaining affordable, safe, and sustainable access to water and sanitation services. thanks go to them for their constant interest in this topic and their intellectual generosity. Global Scaling Up Handwashing is a Water and Sanitation Program (WSP) project focused on learning ...

In performance evaluation of Wheel Slide Protection (WSP) systems, adjustment the control algorithm by an on-track test is most important process. However, since it not easy to stably reproduce low adhesion conditions between wheels and rails in tests, must be adjusted under different for each run. Therefore, solve this issue, we have developed a hybrid simulator that combines real-time compute...
