Families are a social group that frequently visits these sites. There are multiple opportunities for adults and children to engage in independent sense-making and collective discussion about their experiences with...
Ulcerative dermatitis (UD) is a common condition in C57BL/6 mice that is poorly understood and challenging to treat.

An age-wave is upon us where many older adults are reaching retirement. Technically experienced older adults have skills that could be directly applied to free/open source software (FOSS) communities, such as project management, programming, and/or knowledge of a rapidly growing end-user population. FOSS is a widely popular, low-cost way to...
A total of 44 intermittent sand filter-septic systems, in five counties of Western
Oregon, were sampled over a three-month period during the summer of 1995. The sand
filter systems varied in age from 36 months up to 167 months (3 to 13.9 years). Liquid
