Oscillation

Late Victorian Holocausts: El Niño Famines and the Making of the Third World represents a polemically rich work that fails to make the author’s main point: that “the ‘Third World’ is the outgrowth of income and wealth inequalities…shaped most decisively in the last quarter of the nineteenth century” with Asian, African and Latin American economic systems, particularly rural ones characterized by commercial commodity production, joining the larger global economy (15-16). Davis asserts the “Third…

As an employee here at AIM, a youth tennis-based education organization, during my time participating and working alongside our youth athletes, I have become aware that plenty of our athletes enjoy using our tennis ball machines to improve their tennis skills and coordination. However, I have also noticed that our athletes do not use the machines alone. They love to work together, hone in on their tennis skills and even utilize the ball machine for creating games. However, with the organization…

effort to climb the stairs. This wouldn’t be too dramatic, if it wasn’t for the stairs vibrating in time with the group’s march, causing an extremely loud sub-bass oscillation to fill the entire stairwell, reminiscent of the wibble wobble modes caused by shaking a sheet of polycarbonate only much lower and richer. This sub-bass oscillation was almost deafening, and was probably one of the most memorable moments of the soundwalk, as well as a sound I never expected to…

Effects of global warming Introduction Global warming is an ongoing increase in the whole temperature of the earth's atmosphere normally recognized to the greenhouse result caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants. In line for global warming, the normal temperature of the Earth’s surface is progressively increasing. While some argument still occurs over the primary causes of global warming, the Natural Resources Defense Council places the…

How Does Acupuncture Work? Acupuncture is an old, traditional, chinese medical procedure.The philosophy behind acupuncture is rooted in the Daoist tradition which goes back over 8000 years.Daoism is a spiritual, philosophical and religious tradition of the Chinese origin that emphasizes living in harmony with the Tao,also known as the path.Back in the old and new stone age they used sharpened rocks and or bones as the needles for acupuncture, that would later be used for surgical procedures.…

Neurofibromatosis Type 1 is the most frequent autosomal dominant neurogenesis disorder in the United States known today. Considering that school problems are the single most common complication of NF1 that effects the patients’ everyday learning environment entirely (Tonsgard 1, School Problems), neurofibromatosis is a severe genetic disorder that cannot be cured. Neurofibromatosis patients tend to obtain learning disabilities and developmental abnormalities due to brain tumors, attention…

Other records of seawater chemistry provide supporting evidence for changes in tectonic activity and enhanced continental weathering during the formation of the Great Unconformity. For example, the average 87Sr/86Sr of sea water increased during the Neoproterozoic (Fig. 4). This long-term signal is attributable to the increasing concentration of 87Sr in continental crust due to the decay of 87Rb, and to the long-term erosion and progressive exposure of 87Sr-rich granitic rocks required to form…

Is Human Activity Responsible for Global Warming? Over the last century, the global temperature of the Earth had changed drastically. Before the industrial revolution, the Earth’s climate changed due to natural factors rather than human activities; variation in sunlight and volcanic eruption were the natural causes of climate changes in the past. While these natural causes are still in play today, however, their influences are too small compare to human activities ("Is Current Warming Natural?")…

This suggestion received the support of various experiments carried out in animals, and humans. These experiments showed the presence of higher correlation between oscillations of neuron assemblies that represent the features of the object that gave rise to the stimulus. These studies also showed that depending on the oscillation frequency, synchronization has characteristic spatial range, specific brain areas, and links to different cognitive…

In the natural kidney, most components of the blood are first filtered out using ultrafiltration, and then the essential nutrients like glucose, amino acids, etc. and electrolytes like Na, K, Cl, HCO, Ca, Mg, etc. and water are reabsorbed by passive, active, or facilitated transport. The waste products are reabsorbed and therefore are excreted in the urine. The artificial kidney device called hemodialyzers removes excess waste from the blood using the principle of dialysis. The cleansed blood…
