4.0625 | PRINCIPLES OF POND FISH CULTURE
1. Fish are dependent for food directly or indirectly on plants.
2. The weight of fish which can be produced in natural waters is dependent upon the ability of the water to raise the plants. We could increase production by adding plant organic matter produced elsewhere.
3. The ability of... | http://hobiikan.blogspot.com/ |
4.0625 | Tremor is a rhythmic, involuntary back-and-forth oscillation of part of the body. Tremor in children may be caused by familial essential tremor, focal epilepsy, or a psychogenic movement disorder. Tremor is often seen with ataxia, dystonia, or myoclonus. Physiologic tremor is the normal shaking that occurs when people ... | http://endoflifecare.tripod.com/juvenilehuntingtonsdisease/id55.html |
4.34375 | Geometry is heavily tested on the GRE Math section, and a thorough review of geometrical concepts is essential to a high score. Consider the following problem:
“If the length of an edge of a cube X is twice the length of an edge of cube Y, what is the ratio of the volume of cube Y to the volume of cube X?”
The easiest ... | http://www.newgre.org/preparation/sample-math-problem-hip-square-or-cube/ |
4 | Armistice Day, held on 11 November every year, commemorates the signing of the armistice between the Allies and Germany at 11 am on 11 November 1918 - the eleventh hour of the eleventh day of the eleventh month. Although hostilities continued in some areas, the armistice essentially brought an end to World War I.
After... | http://www.educationscotland.gov.uk/resources/a/armisticeday.asp |
4 | Here is a brief sketch of 19th century military organization to help civilians reading history
The combat arms of an army were classified as infantry, cavalry and artillery. Infantry moved by marching, and its weapon was the individual firearm--musket or rifle, replacing the lance of the medieval army. Cavalry moved by... | http://mysite.du.edu/~jcalvert/hist/army.htm |

4.15625 | Smooth muscle is responsible for the contractility of hollow organs, such as blood vessels, the gastrointestinal tract, the bladder, or the uterus. Its structure differs greatly from that of skeletal muscle, although it can develop isometric force per cross-sectional area that is equal to that of skeletal muscle. Howev... | http://www.uic.edu/classes/phyb/phyb516/smoothmuscleu3.htm |
4 | In the years immediately following 1814, the newly organized state fought repeatedly for its existence. Norway was hit by the worst economic depression it had ever suffered. The common market with Denmark was dissolved and the British market was closed to Norwegian timber. Mines and sawmills lost foreign custom. Many o... | http://www.emb-norway.or.th/aboutnorway/history/after1814/unionswe/ |
4.125 | This is an interesting question, because if the strong nuclear force could confine the electron within the nucleus, atoms would collapse. Many electrons in the atom do venture very close to the nucleus (especially those in s orbitals). The uncertainty principle comes into play twice here: it determines the range of the... | http://antoine.frostburg.edu/chem/senese/101/quantum/faq/electron-confinement-to-nucleus.shtml |
4.125 | Aug. 29, 2011 A team of German and Canadian scientists has shown that today's plague pathogen has been around at least 600 years.
The Black Death claimed the lives of one-third of Europeans in just five years from 1348 to 1353. Until recently, it was not certain whether the bacterium Yersinia pestis -- known to cause t... | http://www.sciencedaily.com/releases/2011/08/110829173751.htm |
4 | The rhizosphere is the narrow region of soil that is directly influenced by root secretions and associated soil microorganisms. Soil which is not part of the rhizosphere is known as bulk soil. The rhizosphere contains many bacteria that feed on sloughed-off plant cells, termed rhizodeposition, and the proteins and suga... | http://en.wikipedia.org/wiki/Rhizosphere_(ecology) |

4.09375 | Sea water off the east coast of Greenland looked a bit like marbled paper in October 2012. The shifting swirls of white were sea ice, as observed by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite on October 17, 2012. In fact, this ice moved discernibly between October 16 and October ... | http://visibleearth.nasa.gov/view.php?id=79521 |
4.0625 | Eclipses take place when the Sun is partially or completely blocked from view by some body passing in front of the observer. In a solar eclipse, the Moon passes between the Earth and Sun, and observers in the shadow of the Moon see an annular, partial or total solar eclipse. In a lunar eclipse, the Earth passes between... | http://cseligman.com/text/sky/eclipse.htm |
4.09375 | At the time of acute infection with HIV, the body has not yet made antibodies to HIV. Antibodies, proteins produced primarily by certain white blood cells called B lymphocytes, attack substances foreign to the body, including viruses. The fact that symptoms are present even though the blood test to detect antibodies to... | http://homehealthrx.com/english-hiv-infection-and-its-effects-on-the-body-acute-seroconversion |
4.03125 | Knowing how and where birds migrate and breed is an important part of understanding how and why their numbers increase or decrease over time. However, we don't know much about the exact migratory patterns of most birds. After all, they are one of the most itinerant animals on earth, coming and going from one place to a... | http://nationalzoo.si.edu/scbi/migratorybirds/science_article/default.cfm?id=137 |
4.46875 | To get Excel to perform calculations, such as addition or subtraction, we create a formula. Although writing a formula in Excel is similar to the way you would write a formula in math class, there a couple of important differences.
One difference is that a formula in Excel begins with the equal sign rather than ending ... | http://spreadsheets.about.com/od/exceltips/qt/cell_ref.htm |
4.34375 | Stars form from dense clumps of molecular gas deep inside a cloud. The clumps shrink down until their centers become hot enough (around 10 million degrees) for hydrogen to fuse together. At that point, the energy generated by fusion pushes their outer layers outwards and halts the contraction. The delicate balance betw... | http://spiff.rit.edu/classes/phys230/lectures/star_age/star_age.html |
