Semantic Annotation for Learning Material
This paper aims at providing the specification for semantic annotation tools for e-learning. From the specific requirements of annotating learning material, we categorize and evaluate the existing annotation tools, mainly general purpose ones. We illustrate two research prototypes of annotation tools we developed, and evaluate to what extend the specific requirements of annotating learning material are reached by these research prototypes.

Growing Power Farm: Aquaponics
Aquaculture is the symbiotic cultivation of plants and aquatic animals in a re-circulating system. Growing Power uses Tilapia and Yellow Perch to fertilize a variety of crops and herbs using aquaponics. Currently, we have three Tilapia systems and six Yellow Perch aquaponics systems in our greenhouses at our urban farm in Milwaukee.

Racial/Ethnic Disparities in Preschool Immunizations: United States, 1996–2001
Objectives. We examined current racial/ethnic differences in immunization coverage rates among US preschool children. Methods. Using National Immunization Survey data from 1996 through 2001, we compared vaccination coverage rates between non-Hispanic White, non-Hispanic Black, Hispanic, and Asian preschool children. Results. During the 6-year study period, the immunization coverage gap between White and Black children widened by an average of 1.1% each year, and the gap between White and Hispa
Stage at Diagnosis and Survival in a Multiethnic Cohort of Prostate Cancer Patients
Objectives. We evaluated the effects of socioeconomic status and comorbidity on stage of disease and survival among 1,509 population-based prostate cancer patients. Methods. We applied logistic regression and Cox proportional hazards regression to data from Whites, African Americans, and Asian Americans who were diagnosed from 1987 to 1991. Results. Patients with existing comorbid conditions were less likely than those without these conditions to be diagnosed with advanced cancer. Compared wit
How to Calculate a Biodiversity Index
This brief online article show students how to use a formula called the biodiversity index to describe the amount of species diversity in a given area. The article starts with an explanation of why an environment with a single species of adapted plants is more at risk. Two sample calculations are given along with the formula, illustrating how the formula can be applied to a carrot patch or a forest area.

Platform on Two Rotating Cylinders Model
The EJS Platform on Two Rotating Cylinders model displays the model of a platform resting on two equal cylinders are rotating with opposite angular velocities. There is kinetic friction between each cylinder and the platform. The separation between the cylinders and the coefficient of kinetic friction can be changed via textboxes.
