two monomers to form a polymer (Tarle, 435). A polymer molecule is made up of hundreds, thousands, or even millions of atoms joined together to form a chain with an extended length at least an order of magnitude greater than its thickness (Peacock & Calhoun, 2006). Polymers have variations of molecular weight (length), branching, steric configuration, interconnections and chemical defects (Tarle, 435). A polymer is made up of many elements. One can consider a polymer as a thread with every link

VASILEIOS-MARIOS GKORTSAS vasilisg@mit.edu 6.638 Term Paper Attosecond Pulse Generation Abstract: The word “attosecond” (1 as = 10-18 sec) entered the vocabulary of physics when sub-femtosecond pulses of UV/XUV light were established. High harmonic generation (HHG) is currently the only experimentally proven method for generating attosecond pulses. Attosecond science has opened the door to real-time observation and time-domain control of atomic-scale electron dynamics. In this

Global Warming, aside from pollution is one of the populations biggest concerns. Global Warming is caused by the Greenhouse effect. As mater of fact there are four steps in the Greenhouse effect. The first one is Sunlight radiates from the sun, through space, to Earth/-Es atmosphere. Number two is the sunlight enters the atmosphere and hits Earth. A small portion of it turns into heat energy in the form of infrared light. The heat gets absorbed by surrounding air and land, which in turn makes it

1-16 Protein Motifs Protein motifs may be defined by their primary sequence or by the arrangement of secondary structure elements The term motif is used in two different ways in structural biology. The first refers to a particular amino-acid sequence that is characteristic of a specific biochemical function. An example is the so-called zinc finger motif, CXX(XX)CXXXXXXXXXXXXHXXXH, which is found in a widely varying family of DNA-binding proteins (Figure 1-49). The conserved cysteine and histidine

Up A microcontroller (also MCU or ¥ìC) is a computer-on-a-chip. It is a type of micro-computer element that emphasizing high integration, low power consumption, self-sufficiency and cost-effectiveness, in contrast to a general-purpose microprocessor. In addition to the usual arithmetic and logic elements of a general purpose microprocessor, the microcontroller typically integrates additional elements such as read-write memory for data storage, read-only memory, such as flash memory for code storage

Ozone (O3) Depletion The ozone is a molecule that contains three oxygen atoms and has a strong odor. It is also blue in color. This is much different than the oxygen that we breathe in that it is odorless and colorless. Since around the 1970's there has been a severe problem happening in our Earth's stratosphere. The Earth's ozone layer has been in a great decline of about four percent in total volume observed since then. There are two different but related issues that are happening from mankind
