In recent years, the genre has boomed and essentially changed the landscape of television networks. Meanwhile, many reality shows continue to reinforce traditional race and gender based stereotypes. By critically analyzing and comparing various episodes, cast choices, scenes and other core issues within the context of the seven seasons of The Bad Girls Club BGC , continuous use of negative stereotyping is revealed. From a race lens, the producers casting of an increasing number of racial minorities for drama to reinforce various negative stereotypes is also considered. Docudramas tend to feature documentary-style events with dramatized re-enactments of events that occurred in the past, but are portrayed as reality and edited for entertainment purposes. Kellner suggests that using a cultural studies approach to media allows individuals to read and interpret their own culture critically by manifesting how the dominant culture reproduces certain forms of racism, sexism and biases against members of subordinate classes, social groups or alternative lifestyles.

Ice-sheet dynamics Sampling the surface of Taku Glacier in Alaska. There is increasingly dense firn between surface snow and blue glacier ice. An ice core is a vertical column through a glacier, sampling the layers that formed through an annual cycle of snowfall and melt. At Summit Camp in Greenland, the depth is 77 m and the ice is years old; at Dome C in Antarctica the depth is 95 m and the age years.

The bubbles disappear and the ice becomes more transparent.

How is Carbon 14 produced? A lot of interesting things happen in the upper atmosphere of our world. Much of the high energy photons of the electromagnetic spectrum is filtered out by the time light gets to the surface of the earth: However, in the extreme upper atmosphere there are photons striking the atmosphere of such high energy that they initiate reactions of molecules or even change the nature of atoms themselves.

Ultraviolet light is responsible for initiating chemical reactions through a process called photodissociation. Molecules are torn apart by the energy of the ultraviolet photon. Once the atoms are separated they can then come back together again; possibly, the atoms can form different combinations, thus allowing new molecules to be produced. Ozone is produced in this way, it is produced by the photodissociation of Oxygen. Oxygen is produced from the photodissociation of water. If this large production of Oxygen in the upper atmosphere is a reality, then the reducing atmosphere postulated by evolutionists to allow for the generation of biological molecules, would be in jeopardy.

It is interesting to note that the rocks in the precambrian contain metal oxides. The rocks are not found in a reduced state.

Interactions of an object with another object can be explained and predicted using the concept of forces, which can cause a change in motion of one or both of the interacting objects. An individual force acts on one particular object and is described by its strength and direction. The strengths of forces can be measured and their values compared.

What happens when a force is applied to an object depends not only on that force but also on all the other forces acting on that object.

Nutrient run-off from agriculture and urban sewage are thought to be to blame. When these organisms die and sink to the seafloor, bacteria set to work decomposing them, using up oxygen in the process. The resulting lack of oxygen not only curtails habitats for creatures that live on the seafloor, but also affects fish stocks and can lead to blooms of toxic cyanobacteria. But it is not a problem confined to the Baltic.

Earlier this year a study revealed that ocean dead zones have quadrupled in size since the s , and are found the world over in coastal regions of high population, from Europe to North America and China. Researchers behind the latest study say that while nations are taking action to help waters rebound, individuals can help.

How Carbon-14 Dating Works

Unlike the radioactive isotopes discussed above, these isotopes are constantly being replenished in small amounts in one of two ways. The bottom two entries, uranium and thorium , are replenished as the long-lived uranium atoms decay. These will be discussed in the next section. The other three, Carbon , beryllium , and chlorine are produced by cosmic rays–high energy particles and photons in space–as they hit the Earth’s upper atmosphere.

Oxygen (chemical symbol O) has three naturally occurring isotopes: 16 O, 17 O, and 18 O, where the 16, 17 and 18 refer to the atomic mass. The most abundant is 16 O, with a small percentage of 18 O and an even smaller percentage of 17 O. Oxygen isotope analysis considers only the ratio of 18 O to 16 O present in a sample.

This species and others such as Dryopithecus existed before the hominid line diverged on the path to humans. This lineage ancestral gibbons is believed to have diverged from the great ape and human lineages between 17 and 25 Mya Avers, Oreopithecus ‘s hand closely matches the pattern of early hominids, with a grasping capability including firm pad-to-pad precision gripping that apes are unable to perform presumably as a response to similar functional demands to hominids Moya-Sola et al, Bipedal activities made up a significant part of the positional behavior of this primate Kohler and Moya-Sola, Gorilla and human DNA only differs by 2.

Our DNA differs by only 1. The two species of Pan, the chimpanzee, P. The human ancestral line must have arisen between 5 and 8 million years ago. However, with the many species to be found, the exact sequence of species leading to humanity, has not yet been established. Morphological differences, such as in the pelvis, supports making Neanderthals a separate species, Homo neanderthalensis.

Wednesday 4 August Any event that stops the oxygen supply can cause hypoxia, including drowning, suffocation, choking, asphyxiation and heart attack. The brain is particularly sensitive to a reduction in a good supply of oxygenated blood. Even after prolonged heart surgery when blood circulation has been maintained artificially, sensitive tests have detected minor brain impairment, including memory loss.

Hypoxia of the brain initially causes confusion and dizziness, then unconsciousness and death. If suffocation is the cause of the hypoxia, being allowed to breathe freely again by removal of the obstruction will quickly restore the situation without any damage. But as brain cells can survive for only a few minutes without oxygen, damage to the brain can be rapid.

When there is damage to the oldest part in evolutionary terms – the brain stem and the cerebellum, which are located at the base of the skull – a patient will need life support. These parts of the brain control some of the body’s automatic functions, including blood pressure and breathing. Some reports have suggested that Joy Gardner died of kidney failure.

Although it is possible, doctors say hypoxia is unlikely to cause sudden kidney failure in a patient unless there is an existing kidney condition that is being treated. Kidney failure tends to develop slowly.

British Dictionary definitions for oxygen oxygen noun a colourless odourless highly reactive gaseous element: It is essential for aerobic respiration and almost all combustion and is widely used in industry. Intended to mean “acidifying principle ,” it was a Greeking of French principe acidifiant. So called because oxygen was then considered essential in the formation of acids it is now known not to be. The element was isolated by Priestley , who, using the old model of chemistry, called it dephlogisticated air.

The downfall of the phlogiston theory required a new name, which Lavoisier provided.
