The Kondratieff Wave
Words: 2089 - Pages: 8.... wave cycle can help link smaller wave cycles with the actual world system long wave cycle. Briefly described, there are four quadrants to the K-wave.
In quadrant one we have that “risk is relevant to what the masses think”. In this stage of the K-wave going against mass thinking can result in a very wise choice. Most people can be extremely cautious and pessimistic during this period not knowing what to be cautious about. There is much speculation going on and being one of the first persons to act may give you and advantage.
In the second quadrant nominal rates expand, there’s speculation of hard assets, etc. Gradually paying o .....

Circus Animals
Words: 645 - Pages: 3.... with out water, cleaning becomes a low priority. This is very hard on animals especially elephants who bathe frequently in their natural environment.
But, the circus environment is very different from an animal’s natural habitats. Summer can be hard on animals such as bears, while lions, can suffer more in winter months. Veterinarians qualified to treat exotic animals, are not always present or available. As a result animals suffer and die due to the lack of proper medical attention.
Physical confinement is very harmful physiologically and psychologically. The Born Free Foundation conducted a study that found that 22% of the tim .....

Metabolic Costs Of Generating Force
Words: 501 - Pages: 2.... metabolic rate over the size range of birds measured. However, for a given rate of force generation, birds use on average 1.7 times more metabolic energy than quadrupeds. The rate of energy consumption for a given rate of force generation for humans is intermediate between that of birds and quadrupeds. These results support the idea that the costs of muscular force production determines the energy cost of running and suggest that bipedal runners use more energy for a given rate of force production because they require a greater volume of muscle to support their body weight.
Key words: locomotion, energetics, bipedal, bird, muscle force. .....

Hurricanes
Words: 594 - Pages: 3.... become towering thunderheads.
From outside the storm area, air moves in over the sea surface to replace the air soaring upwards in the thunderheads. The air begins swirling around the storm center, for the same reason that the air swirls around a tornado center.
As this air swirls in over the sea surface, it soaks up more and more water vapour. At the storm center, this new supply of water vapor gets pulled into the thunderhead updrafts, releasing still more energy as the water vapor condenses. This makes the updrafts rise faster, pulling in even larger amounts of air and water vapor from the storm's edges. And as the updrafts speed .....

Determination Of An Unknown Amino Acid From Titration
Words: 1634 - Pages: 6.... because it has a lone electron pair which makes it susceptible to a
coordinate covalent bond with a hydrogen ion. Also, the carboxylic group is a
Lewis acidic because it is able to donate a hydrogen ion (Kotz et al., 1996).
Other forms of amino acids also exist. Amino acids may exists as acidic or
basic salts. For example, if the glycine reacted with HCl, the resulting amino
acid would be glycine hydrochloride (see fig. 2). Glycine hydrochloride is an
example of an acidic salt form of the amino acid. Likewise, if NaOH were added,
the resulting amino acid would be sodium glycinate (see fig. 3), an example of a
basic salt form.

Electronic Stimulation
Words: 640 - Pages: 3.... into the body, or use of interrupted current of low intensity to raise the threshold of the skin to pain.
Studies suggested this therapy is applied to conditions such as ulcers, traumatic or burn wounds, osteoarthritis, and cancer. Electrical stimulation is simply the application of electrical pulses to the body, whether it is for function or therapy. The classical and common example is that of the cardiac pacemaker. The range of clinical uses of electrical stimulation has and is growing wider and includes: pain relief (often known as TENS - Transcutaneous Electrical Nerve Stimulation), maintaining or increasing range of movement, muscle .....

The Prairie Dog: Friend Or Foe?
Words: 1768 - Pages: 7.... dog towns leave the animals vulnerable to disease and natural catastrophes. Populations are even limited on the land that is available. Current policies on National Grasslands and other federal lands typically limit prairie dogs to small percentages of available potential habitat.
Prairie dogs are essential to our prairie ecosystem. Many species dependent on prairie dogs for prey and habitat are diminishing in direct relation to the decreasing number of prairie dogs. Unlike other species, which have declined because of habitat loss due to human activities, the loss of prairie dog populations is a direct result of governmental and privat .....

Cloning And Its Impact
Words: 1028 - Pages: 4.... and places it in the egg or another individual, from which the nucleus has been removed (Wertz, 1998b). The change in phenotype, the observable physical and biochemical characteristics of an organism, of livestock is accomplished by bombarding embryos of livestock with genes that produce “super” livestock traits; however, this technique is not efficient because only five percent of the offspring express these “super” traits that would guarntee a more productive industry. Scientists can easily genetically alter adult cells; therefore, cloning from an adult cell would make it easier to alter the genetic material. The goal of trans .....

Often s and many other invigorated species are referred to as "generalists." This has to do mainly with how and what they eat. In this respect, few other creatures have such catholic tastes or more ingenious methods of satisfying them as have s (Gilbert, 1991, p. 69).
The list of what exactly the consumes is quite extensive. Eighty percent of their diet is rodents. However, they will eat pretty much whatever they can find. Watermelons are also a food source for this omnivorous and carnivorous sp .....

By 1900 were no longer found in Syria; today Asiatic are limited to the Gìr Sanctuary in India. also roam Africa south of the Sahara, particularly the Serengeti National Park in Tanzania and the Kruger National Park in South Africa. This drastic reduction in range came about as humans and domestic livestock spread into savanna lands. Because live in open areas, they are easily shot by hunters and herders.
fur coats are a highly prized possession by poachers, and are worth a lot. Over the last 200 years, over 90% of the world’s lion populati .....
