The Function of the Liver
Did you know that the liver is the largest organ in the human body? Learn more in this computer-animated video (04:02)Â that describes where the liver isÂ in the body andÂ its function. This video has English captions at the bottom of the screen. This may be good for big classrooms where sound may not travel well.
Note: There is a little static as the narrator appears to be too close to the microphone while speaking. Also, in the summary the word 'learned' is spelled incorrec

Caves - Extreme Conditions for Life
For certain life forms on Earth, conditions that humans and other familiar organisms find hospitable can actually be deadly. Instead of a moderate climate with an atmosphere rich in nitrogen and oxygen, these organisms thrive in very hot or very cold temperatures, or in caves or deep waters where no light penetrates. In this video segment adapted from NOVA, scientists analyze communities of cave-dwelling microbes that live off simple inorganic compounds like iron and sulfur. Based on their findi

Proteins: Structure and Function

Proteins are very important to living organisms and to industry. Proteins are part of the chemistry of life, and the program examines proteins â€” polymers built from only 20 basic amino acids. The arrangements of these long chains of amino acid are important to their functioning. The video also explores the history of the discovery of the structure and function of pr

Sequence effects in solving knowledge-rich problems: The ambiguous role of surface similarities
Sequence effects are said to occur whenever the problem solving performance varies as a function of the order in which problems are solved. We present a framework that explain sequence effects as a result of (a) learning during solving a problem and of (b) transferring the learned content on succeeding problems. In two experiments we studied the ambiguous influence of surface similarities among structurally dissimilar knowledge-rich problems on sequence effects. These experiments demonstrate tha

Improving database design teaching in secondary education: action research implementation for docume
Database design and use has educational interest for utilitarian and learning reasons. Database technology has significant economic impact and the demand for database design can not be covered by the existent educated experts. Furthermore the database management systems available at schools could be used for the design and implementation of high quality learning activities. Databases are general purpose modeling environments that enable problem solving using conceptual frameworks closer to the s

Looking Ahead to Select Tutorial Actions: A Decision-Theoretic Approach
We propose and evaluate a decision-theoretic approach for selecting tutorial actions by looking ahead to anticipate their effects on the student and other aspects of the tutorial state. The approach uses a dynamic decision network to consider the tutorÂ’s uncertain beliefs and objectives in adapting to and managing the changing tutorial state. Prototype action selection engines for diverse domains Â– calculus and elementary reading Â– illustrate the approach. These applications employ a rich mod

Endometrial Cancer: Socioeconomic Status and Racial/Ethnic Differences in Stage at Diagnosis, Treatm
Objective. We evaluated the association between socioeconomic status and racial/ ethnic differences in endometrial cancer stage at diagnosis, treatment, and survival. Methods. We conducted a population-based study among 3656 women. Results. Multivariate analyses showed that either race/ethnicity or income, but not both, was associated with advanced-stage disease. Age, stage at diagnosis, and income were independent predictors of hysterectomy. African American ethnicity, increased age, aggressi

Building a testbed for mini quadrotor unmanned aerial vehicle with protective shroud
Potential applications of small rotorcraft unmanned aerial vehicles (UAVs) range from military missions to exploration of the planet Mars (Patrick C. Oâ€™Brien, 2003). Tasks such as exploration of unknown territories, formation flying, intelligence gathering etc, require UAV to be capable of flying very close to other flying or steady objects. Exposed rotary wings limit rotorcraft vehicleâ€™s capability to fly in proximity of other objects. In some applications, such as rescue operation, urban w
