for buffering and rapid removal. Lactic Acid as an Energy Source · Lactic acid allows high rates of ATP production for short duration (2-3 minutes). · As exercise intensity slows or during recovery sufficient O2 available again NAD scavenges H+ from lactate and takes it to the ETC lactate reconverts to pyruvate to join oxidative system. Cont... · Lactate helps the dissociation of O 2 from haemoglobin · At higher intensities of exercise lactate production outstrips the cell's removal capacity, thus accumulation occurs. Cont... · Endurance trained: lower blood lactate concentrations than untrained individuals at both the same relative and absolute intensity.

summers. Some animals have grown thick fur that turns white in the winter. Others find a place to hibernate during the winter months. Many plants have dark red leaves that allow the plant to absorb more heat from the sun in the cold tundra climate. All of the plants are adapted to sweeping winds and disturbances of the soil. Many plants grow in a low, tight clump - this growth habit helps protect them from the cold and snow. They can carry out photosynthesis at low temperatures and low light intensities. The growing season is short and most plants reproduce by budding and division rather than sexually by flowering. There are no deep root systems in the vegetation of the tundra; however, there are a wide variety of plants that are able to resist the cold climate. The fauna is also diverse. Animals such as mammals and birds also have additional insulation from fat. Many animals hibernate during the winter because food is not abundant. Another alternative is to migrate
have had all of the surrounding electrons stripped during their high-speed (almost the speed of light) passage through the Galaxy. Cosmic rays provide one of our few direct samples of matterfrom outside the solar system. The magnetic fields of the Galaxy, the solar system, and the Earth have scrambled the flight paths of these particles so much that we can no longer point back to their sources in the Galaxy. If you made a map of the sky with cosmic ray intensities, it would be completely uniform. So we have to determine where cosmic rays come from by indirect means. One of the indirect observations we can make is the "composition" of GCRs. This can tell us a lot about the GCR sources and the cosmic rays' trip through the Galaxy. The "composition" of cosmic rays describes what fraction of cosmic rays are protons, what fraction are helium nuclei, etc. All of

bigger with a lot of energy inside them. Physics of wave energy To have a better understanding of the technical possibilities to harvest the energy out of waves to convert it into electric energy it may be helpful to have a look onto the physics of wave formation, the forces which attack and the characteristics of water waves. Wave formation There are three different momentum responsible for the formation of waves. The moon, earthquakes and wind in variable intensities. Energy of waves vs. period and responsible momentum 2 Three forces to attack the waves There are three forces that are responsible for wave formation. Two of them (gravitational force and Coriolis force) are supporting the formation, one of them (surface tension) reduces the high of waves. At first the gravitational force: This one out of four forces in physics is dominant for wave generation
might produce a large value from the blue CCD, a smaller value from the green CCD, and zero from the red CCD. To get a monochrome (light/dark) representation, the data from the three CCDs has to be averaged Sensors 77 Figure 3.21 Trilinear data alignment. or summed. To get color information, the software has to calculate the actual color of the target from the relative intensities of the three CCD outputs. In short, a color system will produce three times as much data as an equivalent monochrome system, but may require more than three times as much pro- cessing capability. Area CCDs An area CCD is typically used where neither the target nor the CCD is moved to take an image. As the name implies, an area CCD images a square or rec- tangular area. Area CCDs are used in camcorders and surveillance cameras,
