The S-band portion of the microwave band of the electromagnetic spectrum ranges from 2.0 to 4.0 GHz.‚ crossing the boundary between UHF and SHF at 3.0 GHz. The S-band wavelength is around 10 cm. The maritime industry shares S-band radar with other entities permitted by the Federal Communications Commission (FCC) in this country and by the International Telecommunication Union (ITU) worldwide; and this permission is granted to such entities as weather services‚ police and fire departments.

So the topics that follow are ones that I found importance in and were used very frequently to solve the problems in this semester. The topics to come are Shear Stresses for Beams in bending‚ Castigliano’s Theorem‚ Distortion Energy Theorem for Ductile Materials‚ Mechanics of Power screws‚ and Fatigue loading

The introduction of the microscope as a tool for the biologist brought about a complete reappraisal of the micro- composition of biological tissues‚ organisms and cells. In the infancy of its application to organic materials‚ it was the implement of anatomists and histologists in particular‚ where previously unimagined structures in cells were revealed. More recent developments in biological specimen preparation have come from biochemists and physicists who have used the microscope to examine cells

Gymnastics is a sport that has 4 apparatus Vault‚ Uneven Bars‚ Floor and Balance Beam. In this essay I will have three main topics. The first one is gymnastics events where I talk about all 4 apparatus of gymnastics. The second topic is the three main types of gymnastics. Rhythmic‚ Artistic‚ and Acrobatic. The final topic is the history of gymnastics. Gymnastics has been a sport for 4‚000 years‚ but has been an Olympic sport for 32 years. The first apparatus I will be talking about is vault

Particle Fever directed by Mark Levinson‚ is a documentary about a scientific experiment which took almost twenty years to complete. Although it involved ten thousand engineers from one hundred different countries‚ it depicts the experiences of just a few scientists. In the film‚ each scientist describes the journey that they went through in order to complete the complicated project. Costing up to ten billion dollars‚ it was one of the world’s most expensive science experiments. In addition‚ it caused

of its ability to control cell growth. Ionizing radiation works by damaging the DNA of exposed tissue leading to cellular death. To spare normal tissues (such as skin or organs which radiation must pass through to treat the tumor)‚ shaped radiation beams are aimed from several angles of exposure to intersect at the tumor‚ providing a much larger absorbed dose there than in the surrounding‚ healthy tissue.” (Cancer Research U.K.). There are two main types of radiotherapy‚ internal and external. The

Truss bridges are recognizable because of their numerous‚ relatively small interconnected triangles. This framework of triangles is used for is strength to withstand tension and compression forces. They are considered a light-weight yet a very stiff form of construction. At first they were built of wood‚ then with the discovery of welding they began to build then using iron‚ then steel. Occasionally‚ a combination of the materials may be used. There are actually 30 different kinds of truss bridges
