Balance and flux
Ecosystems and populations of organisms within ecosystems function by the principle of balance and flux. Balance can be thought of as a state of equilibrium, or a state of equal changes between two sides. Flux can be thought of as a rate of flow or changes. Even small changes in an ecosystem's or population's balance and flux could lead to disaster.
Artemia blood circulation
Artemia blood circulation in the head and around the gut.
Human arm muscles are connected to the bones by things called tendons. Tendons are rope-like fibers that join muscles to bones and allow movement.
One reason why ticks are considered to be arachnids is because they do not have antennae like insects do. Ticks suck blood from animals and are sometimes difficult to remove from the host's skin.
Apple Screen 1
The apple has just fallen from the tree and rests on the ground.
Roots can grow in multiple directions. Just because this plant was in a cup didn't stop the roots from growing longer and creating individual branches.
Land snails are invertebrates because they do not have a backbone. They are related to water snails, but they do not live in water.

Animation of a CFC molecule being split by a photon
Global Methane Isosurface Wave
An animation of a three-dimensional isosurface of global methane in the atmosphere evolving over time, from a global data assimilation model. The globe of the Earth starts out opaque, then becomes transparent in order to more clearly see the structure of the isosurface. The isosurface exhibits wave breaking in the southern hemisphere.
Cloud Cover over Borneo: March 1, 1998

Numerical Simulation of Magnetic Flux Emerging Through a Model Solar Atmosphere: Density, Magnetic F
This animation is one of a series depicting the results of a two-dimensional ideal magneto-hydrodynamic simulation of magnetic flux emerging through a solar atmosphere. The simulation has a resolution of 300x500 cells and a length scale of 16 Mm x 6.8 Mm. The simulation depicts 1730 seconds in the evolution of the model.
El Nino-La Nina Sea Surface Temp and Height Anomaly 3D Isometric View: January 1997 through November
An animation of sea surface temperature and height anomalies in the Pacific for January 1997 through November 1998 from NOAA AVHRR and TOPEX Poseidon
North America NDVI 1993 August
NDVI in North America for August 1993, based off data collected over the 1981-2000 time frame.
1993 Daily Ozone from Meteor-3
In this animation of total ozone, the luminance values of the colors bounding areas of missing data are used in interpolating over these regions. The missing data are mapped to the grayscale portion of the color map.
Water and Sanitation Needs in Complex Humanitarian Emergencies
Presents a historical overview of the influence of water and sanitation on human health; types of water and sanitation facilities and equipment presently available and particularly suited to refugee populations displaced by war, famine, drought, and economic turmoil; and methodologies for assessing and quantifying water and sanitation needs.
Adolescent Health and Development
The course consists of lectures, readings, discussions, panels of guest speakers, group and individual projects. The purpose of the lectures, readings, discussion and panels of guest speakers is to explore a variety of aspects of adolescence and adolescent health. The group and individual projects are meant to help students develop skills to work in multi-disciplinary teams and analyze adolescent health concerns through conceptual frameworks and recommend effective solutions through intervention
The History of Public Health
In the History of Public Health we will examine the historical experience of health and illness from a population perspective. This material seeks to reveal how the organization of societies facilitates or mitigates the production and transmission of disease. It also asks how do populations and groups of individuals go about securing their health? One key theme is the medical management of space in one form or another - from the public space of the environment through institutional spaces such a
Social and Behavioral Foundations of Primary Health Care
Social and Behavioral Foundations of Primary Health Care aims at providing you with the knowledge and skills needed to diagnose (understand) community, individual, and organizational behaviors and change processes in developing countries and in cross-cultural settings as a foundation for planning culturally appropriate primary health care (PHC) in the context of the ecological model of health behavior.
