The Northwest Coastal Indians‚ Kwakiutl‚ lived in what is now Alaska along the Pacific Ocean down the coast to Northern California. The environment was very diverse and often extreme which included a rugged strip of land with small islands‚ deep inlets‚ inland rivers and lakes‚ deep fjords‚ and wide and narrow beaches. Mountains rise to the shore in many places. Spruce‚ cedar‚ and fir forests dominated the area supplying endless amounts of wood. All the people lived near the water and relied heavily

Humans have tried to predict the weather for millions of years. Our ancestors monitored changes in their environment along with the behaviour of animals to help them predict the weather. Through development of our understanding‚ of the atmospheric patterns and the relationship to weather dynamics‚ today it is much easier to forecast a more accurate weather prediction. To better understand the mechanisms which control our weather and climate‚ we have to look at the Earth’s atmosphere. In particular

entire game in the opponent’s end of the field‚ they are not allowed to cross the midfield line‚ and the attack men have to be very agile and quick because they take the most shots on the goal. The third position is the defenders or also known as long poles; they are the players who dictate to the opponents attack where they can go‚ and where they will be punished for going. They need to be very physical. They have much longer sticks up to nearly 60" long which allow them to disrupt the opponents attack

To achieve your goal is not to work harder but to work smarter. If you work too hard‚ it would lead to stress and despair‚ and to work smarter would be a quicker way to work and unstressful. Harold Courlander was the author of “All Stories are Anansi’s”‚ an african folktale. The theme of this story is “working smarter than harder”. “Working smarter than harder” means to work efficiently‚ to strategized‚ and quicker than to work hard which makes things harder. “Working smarter than harder” shows

Earth heated up to melt Iron&Nickel to create a core. Heated by meteorite impact‚ gravitational compression‚ &radioactive decay the iron/nickel weigh more than silicates so settled to earth’s center. 3. Earth was formed consisting of a dense iron-nickel core; an iron-rich silicate mantle and a silicate crust with continents emission of gases

1. What are the causes of skin cancer? Exposure to abnormally high frequencies of light can potentially alter the DNA of a cell and turn it cancerous‚ the resulting cancerous cells are known as skin cancer. The most common cause is ultraviolet light emitted by the sun although it has been known to be caused by tanning booths‚ unusually high levels of x-rays‚ exposure to some chemicals and in rare cases the abnormal genes that cause skin cancer can be inherited by children from their parents.

Jeffrey H. Lang‚ Member‚ IEEE‚ and Pradnya Nagarkar Abstract-This paper presents a detailed discussion of micromotor fabrication and related critical issues. The micromotors under study are of the variable-capacitance side-drive type with salient-pole and wobble (harmonic) designs. Polysilicon surface micromachining forms the basis of the micromotor fabrication process. In this process‚ LPCVD heavily phosphorus-doped polysilicon is used for the structural parts. LPCVD silicon nik d e is used for

Compound Microscope Parts A high power or compound microscope achieves higher levels of magnification than a stereo or low power microscope. It is used to view smaller specimens such as cell structures which cannot be seen at lower levels of magnification. Essentially‚ a compound microscope consists of structural and optical components. However‚ within these two basic systems‚ there are some essential components that every microscopist should know and understand. These key microscope parts are illustrated
