Thermal Expansion happens a lot in everyday life. When something is heated and expands this is Thermal Expansion. The way Thermal Expansion works, is when it is heated the atoms expand, and then when it is cooled it shrinks. Several examples of Thermal Expansion would be some of the following:
· When mercury in a thermometer rises it is because of thermal expansion.
· Thermal Expansion caused sometimes when you see cracks in concrete that have spread it.
· Take a thermostat, there are two pieces of metal in a thermostat, when it gets heated up the pieces of metal spread apart and shuts the furnace off, and when it cools back down the two pieces of metal touch each other and that triggers the furnace to come back on.
· Power lines can be an example of Thermal Expansion. In the summer when it is hot you will notice that the power lines hang down lower because they expand from the heat, so then in the winter you will notice they will tighten back up.
· A metal roof is a good example of Thermal Expansion. When the sun hits a metal roof it will expand then when it cools down you can hear it popping and cracking because then it contracted.
Those are just a few examples of Thermal Expansion, you can see this is very common in things that we are around. on would be some of the following:
· When mercury in a thermometer rises it is because of thermal expansion.

Transparent!

...Researchers in Japan have made a crab shell transparent. Then, using knowledge gained from this activity, they created a transparent nanocomposite sheet, incorporating powdered chitin from crab shells. The nanocomposite could have applications in devices that need a high light transmittance, such as flat panel displays. Scientists have previously used cellulose from plants and chitin to strengthen materials, giving biologically-inspired nanocomposites. If natural nanofibres are dispersed widely enough in a transparent polymer matrix, they can strengthen the polymer and the resulting nanocomposite material will retain its transparency. Work on optically transparent polymers containing cellulose nanofibres shows they have a low axial thermal expansion coefficient, meaning their size does not vary with temperature, making them ideal for use in flexible flat panel displays and solar cells. Muhammad Iftekhar Shams and co-workers from Kyoto University took a whole crab and treated it with hydrochloric acid, sodium hydroxide and ethanol to remove the minerals, proteins, fats and pigments, respectively. This gave a chitin-only crab shell, which they immersed in an acrylic resin monomer. Following polymerisation, they obtained an entirely transparent crab shell. The shell retained its shape and detail, right down to the creature's eyes.  Preparing the transparent crab shell: (a) original shell, (b) shell after removal of matrix substances and (c) transparent crab shell after immersion...

Piping Expansion Joints

...EXPANSION JOINTS T. N. GOPINATH 1. INTRODUCTION When piping lacks inherent flexibility due to routing and/or develops large reactions or detrimental overstrain on the strain sensitive equipments, the Piping Engineer considers provision of expansion joints to overcome the same. Expansion joints are also provided to isolate the vibrating equipment from piping and also to facilitate free movement of the equipment mounted on load cells. 2. TYPES OF EXPANSION JOINTS The expansion joints can be slip type or the bellows type. 2.1 Slip Type of Expansion Joint In slip type of expansion joint one pipe slides into another and the assembly is sealed by means of packing between the sliding pipes. This device has the limitation that it permits only axial movement in the direction of pipe axis. Small amount of lateral and/ or angular movement will cause binding and eventually leakage. It is extremely difficult to seal it off completely. The limitations on packing makes it suitable only for very low temperature and low pressure services. Fig 2.1 indicates the general arrangement of a slip type expansion joint. [pic] Fig 2.1 2.2 Bellow Type Expansion Joint The bellow type expansion joint is extensively used as the most efficient and functionally reliable elongation compensator and/ or vibration isolator. These are capable of compensating for large amounts of axial and/...

Second is the NLX, which is for low end personal computer, supports riser card which adds expansion slots. Third is the BTX which is compatible with all ATX functions but is designed for better airflow and cooling. By having an intake vent at the front and an exhaust vent on the back along with having the CPU and memory modules installed parallel to the direction of the airflow, the BTX achieves its cooling functions. Communication buses are also explained. They are copper tracing on the bottom of the mother board and they make up the bus system. Often described as highways. Buses connect to various components and allows power and data between the CPU, Hard Drive, key board, mouse, USB devices, sound cards and any other components. System bus is the largest and fastest bus, it connects to the mother board and it carries data between the CPU and the mother board and vice versa. There are various connectors on a mother board one of them is the power connector known as the p1 connector. P1 has a 20 pin connector or a 24 pin connector. The 40 pin IDE, 34 pin Floppy drive connector, SATA connectors and the 50 or 68 pin SCSI otherwise known as Scuzzy.

...analyze, and evaluate the significant influences that work for or against its strategic objectives (Sultz & Young, 2009). Strategically planning will help aid Sandwich Blitz with the decision of expanding and locating new locations. It allows for all management persons to get involved in the process. Although I believe that the expansions should be on small scale because this allows them time for growth if the new expansion takes off. The biggest STRENGTH of Sandwich Blitz is that they have the resources to open two additional locations if good locations can be found. Another strength would be, that they have the staff to move to these new locations. This also allows for low level management to get involved in the marketing of the new expansions. A major WEAKNESS of Sandwich Blitz is that due to the recent economic downturn, the larger park offices have been affected and this could affect business because people are probably not shopping in these areas too much. They would probably have to come up with cheaper menus and do specials to attract business which could be costly. The OPPORTUNITY for Sandwich Blitz would be that the expansion allows for more business especially if it is moved to another city. The new city may not have top competitors or mimics of Sandwich Blitz and this allows to them to enter another market. Another opportunity is that it can bring about new business and more customers for the franchise. It also gives them the opportunity to create new...
