Atom Book
... Helium atom today. An atom is made of little things
called protons, nuetrons, and electrons. Protons have a positive charge,
neutrons have no charge, and electrons have a negative charge. Electrons travel
around the center of the atom, which is called the nucleus. Kind of like how
Earth revolves around the sun. Protons and nuetrons make up the center of the
atom.
The atom has an atomic number. Scientists find that number by counting how many
protons are in the nucleus. In this case Helium has two protons.
Scientists find the average atomic mass by adding up protons and neutrons many
times. Then they divide the ...

Plutonium
... Americium (Am), Curium (Cm), Berkelium (Bk),
and Californium (Cf). In addition, Seaborg later contributed to the discovery
of three more radioactive elements, Einsteinium (Es), Mendelevium (Md), and
Nobelium (No). Plutonium was Seaborg’s first discovery. Its name came from
Pluto, the planet after Neptune for which Neptunium was named. In 1940, at the
University of California at Berkeley, he bombarded a sample of Uranium with
deuterons, the nuclei in atoms of deuterium, transmuting it into plutonium.
Shortly after, Seaborg was able to isolate plutonium 239, an isotope used in
atomic bombs.
Plutonium is ...

The Use Of Pollen Analysis In
... survive in most conditions; the only environments which are truly hostile to this shell are abrasion, such as may be the case on sandy sites, and oxidation. However, the most favourable conditions for preservation of the pollen record are acidic, anaerobic sites such as peat bogs. This high degree of survivability combines with another factor inherent in the nature of pollen - the large amount produced - to make pollen analysis one of the most important tools available to the archaeologist. Though one further factor in the make-up of pollen enhances its value, namely the wide morphological variation between poll ...

Knee Surgery
... and perseverance. In my naive thinking, surgery was an athletic badge of honor to be displayed on one's knees with corrugated streaks of purplish flesh. Little did I realize what it takes to recover. My father had orthoscopic surgery twice, and both times he was walking within a day and cycling within a week. I assumed my recovery time would be similar to his. Never in my life have I been so wrong. Due to the nature of the injury, the doctor elected to stitch my cartilage back together. Because of the intricacy of the operation, I was restricted to non-weight bearing activities for three weeks. I ...

Leprechaunism

is an autosomal recessive, Mendelian inheritance pattern. As stated before, both males and females can be affected. Its occurrence is associated with consanguineous relationships. A consanguineous relationship means that the parents are genetically related (e.g. first cousins).
Clinical traits are as follows:
Hyperpigmented skin or as otherwise known, Acanthosis nigricans. This symptom is not exclusive to , as it is caused by high insulin levels. This pigmentation normally occurs in areas of the body where flexing an ...

Nuclear Fission
... as uranium. The neutron splits the uranium atom. When the atom is split, it releases two more neutrons. These neutrons can then strike two more uranium atoms. The split of each atom will produce two more neutrons. The more atoms that are split the more neutrons produced that will split more atoms. As this process is repeated over, it becomes a self-sustaining chain reaction. This energy producing process is called a chain reaction.
uses the uranium-235 element because it is the easiest of all atoms to split apart. Uranium-235 is made up of many protons and few neutrons. Protons naturally repel one another so ...

A Study Of B.F. Skinner And Behaviorism
... rewards, and other aspects of behavioral psychology will be discussed to give a better understanding of B.F. Skinner and his studies.
A Study of B.F. Skinner's Behaviorism
B.F. Skinner is an American psychologist who is best known for his research into the learning process and his idealist view of having a planned society. He was born in Susquehanna, Pennsylvania in 1904. He graduated from Hamilton College in 1926. After becoming interested in the works and studies of John B. Watson and Ivan P. Pavlov, he studied with animal learning and functions of the nervous system. He received his Ph.D. in behavioral psycholog ...

Mitochondria
... which dramatically increase the
surface area of the inner membrane. Cristae extend into a dense material called
the matrix, an area which contains RNA, DNA, proteins, ribosomes and range of
solutes. This is similar to the contents of the chloroplast stroma and like the
chloroplast, the mitochondrion is a semi-autonomous organelles containing the
machinery for the production of some of its own proteins. The main function of
the mitochondrion is the oxidation of the pyruvate derived from glycolysis and
related processes to produce the ATP required to perform cellular work.(Campbell
182-9)
Pyruvate, or fatty aci ...
