"Astrodynamics, Fall 2008"
" This course covers the fundamentals of astrodynamics, focusing on the two-body orbital initial-value and boundary-value problems with applications to space vehicle navigation and guidance for lunar and planetary missions, including both powered flight and midcourse maneuvers. Other topics include celestial mechanics, Kepler's problem, Lambert's problem, orbit determination, multi-body methods, mission planning, and recursive algorithms for space navigation. Selected applications from the Apoll
Mental Health: Depression
Clinical depression is a serious illness which leads to persistent low mood, loss of energy and motivation, and a reduced ability to feel pleasure. It interferes with day-to-day life by producing negative thoughts and a variety of physical symptoms. Indeed physical symptoms are so important that it is more usual for patients with depression to go to their doctor with a bodily complaint than with a complaint about their mood, so it is vital that doctors understand that depression may be a “hidd
Gait Exam: Abnormal Examples: Ataxic Gait
This woman's gait is wide-based and unsteady. She has to use a walker or hold on to someone in order to maintain her balance (note how hard she has to work with the hand that she's holding on with in order to maintain her balance). Her ataxia is even more apparent when she tries to turn. The first principle of neurologic diagnosis is regional or anatomical localization. In order to become skillful the student must understand how structure relates to function of the nervous system. The neurologic
Microscopy of Air/Water Biofilms in the Undergraduate Laboratory: A Simple Collection Kit with Multi
Naturally occurring air/water interface biofilms are ubiquitous, but largely unexplored. They provide ideal samples for introductory microscopy and microbiology. This activity introduces a simple method for collecting samples from nature or the lab and gives detailed instructions on preparing a simple collecting kit and optimum viewing with student microscopes. Useful features of this activity include: the ideal nature of a wide assortment of ubiquitous air/water interface biofilms for microscop

Wild Wind
Students will learn the difference between global, prevailing and local winds. In this activity, students will make a wind vane out of paper, a straw and a soda bottle and use it to measure wind direction over time. Finally, they will analyze their data to draw conclusions about the prevailing winds in their area.

This lesson based on conversation about sports and extra activities which will help the pupils learn the new material.
Hurricane Gert from TRMM: September 16, 1999
A fly-in to Hurricane Gert on September 16, 1999, showing the three-dimensional structure of the precipitation as measured by the Precipitation Radar instrument on TRMM. In this animation, a surface of constant precipitation is colored by the value of the precipitation on the ground under the surface. The global cloud cover data was measured by GOES.
Hurricane Georges from TRMM: September 23, 1998
A fly-in to Hurricane Georges on September 23, 1998, showing the three-dimensional structure of the precipitation as measured by the Precipitation Radar instrument on TRMM. In this animation, a surface of constant precipitation is colored by the value of the precipitation on the ground under the surface.
Hurricane Floyd from TRMM: September 13, 1999
A fly-in to Hurricane Floyd on September 13, 1999, showing the three-dimensional structure of the precipitation as measured by the Precipitation Radar instrument on TRMM. In this animation, a surface of constant precipitation is colored by the value of the precipitation on the ground under the surface. The global cloud cover data was measured by GOES.

An Overview of SeaWiFS and the SeaStar Spacecraft
Visitors can read and view animations and a movie that describe the SeaStar spacecraft and the SeaWiFS instrument. Materials presented here explain the physical characteristics of the vehicle, its launch procedure and orbit, and the capabilities of the instrument. Links to related topics are provided.
7.2.1 The ‘what’ pathway
Hearing is a familiar and important human sense that is a topic naturally of interest to those who are curious about human biology. This unit will enable you to relate what you read to your own sensory experiences – and indeed many of the questions asked have exactly that function. This unit will be best understood by those with some biological understanding.
