Moral and ethical principles in end of life care
In many areas of health care, and especially in such areas as palliative care, increasing attention has been paid in recent years to patient autonomy, and the need to respect it. Autonomy has come to be seen as a very important aspect of the interaction between patients and those looking after them, and forms the basis for many ethical commitments, such as telling the truth to patients, and seeking their consent for health care interventions. In this unit we look at quite a wide range of ethical
Breathing tube of a mosquito larvae
The breathing tube is one organ of the respiratory system (along with the lungs in animals). The breathing tube allows for the intake of oxygen and the disposal of carbon dioxide.
Boy on trampoline
The boy would feel less secure if the safety net around the trampoline wasn't there. Humans have an innate need to feel secure in their environments.
Fly on a leaf
Flies are insects that eat dead plant and animal material. Their ingestion and digestion of detritus leads to respiration and excretion of important nutrients back into the soil and water.
Celery in pure water
The celery stalks take up the water and continue to live in this environment.
AMSR-E Anomalous Atlantic Sea Surface Temperature Data Used to Forecast 2003 Hurricane Season 1
Researchers and forecasters often study sea surface temperatures for an indication of hurricane potential. Scientists say above normal Atlantic Ocean temperatures is one reason for the "above normal" hurricane forecast. Hurricanes convert heat from the tropical atmosphere and oceans to wind and waves, just as a car engine converts gasoline into motion. These animations show a year in the life of global ocean temperatures, June 2, 2002 to May 11, 2003. Green indicates the coolest water, yellow th
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.
Global Longwave from CERES
CERES stands for Clouds and the Earths Radiant Energy System.
Arctic Ozone from February 1, 2003 through March 30, 2003
This visualization shows the northern hemisphere ozone hole from February 1, 2003 through March 30, 2003.
The Middle East Dust Storm
Dust storms are an every day occurrence in Saudi Arabia. This storm is of an unusual size.

Numerical Simulation of Magnetic Flux Emerging Through a Model Solar Atmosphere: Density
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.
High Resolution 2-D Numerical Simulation of Emergence of Magnetic Flux Through the Solar Atmosphere
This series of animations (animations 107, 1416, 1417, and 1418) show sheets of magnetic flux undergoing velocity perturbations. The conditions for each simulation are outlined within the video.
Great Zoom Mosaic - Zoom Out
This is a mosaic of zooms out of 20 different locations prepared to support a paper given at IEEE Visualization 2002. The locations are: Long Beach, CA; New York City, NY; San Fransisco, CA; NASA-Goddard, Boston, MA; New Orleans, LA, Salt Lake City, UT; Sabie River, Africa; Park City, UT, Chicago, IL; Mongu, Africa; Salt Lake City, UT; Amazon, Brazil; Los Angeles, CA; Baltimore, MD; Snow Basin, UT; Atlanta, GA; Washington, DC; Orlando, FL; and Seattle, WA. Using data from different spacecraft an
Great Zoom into Siberia
Using data from different spacecraft and some powerful computer technology, visualizers at the Goddard Space Flight Center present you with a collection of American cities in a way you have never seen them before. Starting with our camera high above the Earth, we rush in towards the surface at what would be an impossible speed for any known vehicle. Passing though layers of atmosphere, the colors of our destinations shimmer with their own unique characteristics, and suddenly we find ourselves fl
