different types of electrical generators. Fig(1) shows the construction of wind energy system the wind turbines connedted to the electrical generator throgth the mechanical system( gearbox), as the electrical generator produce AC voltage source the diode bridge convert it to DC source. There are some energy stored in battery bank before the rest power inverted again from DC to AC source. Fig(1) The power energy available in wind can be expressed in mathematical equation as: = Air…

This movie has begun in Princeton University on September 1947. It starts with a class of guys listening to a professor on how each of the guys in the class was awarded a scholar ship to study in Princeton. Then there comes a guy name John Nash, who is the main character in this movie. From this, it will tell a story about John Nash and will also talk about his disorders in this movie. The group of guys that where in the class are now outside and talking to each other and getting to know with…

The authors created the Accelerated Sensor of Action Potentials 1 (ASAP 1) using a green fluorescent protein source on the extracellular side of the plasma membrane to highlight the membrane potential changes as demonstrated by the fluctuation in the fluorescent brightness. Neuronal action potentials generated are monitored up to 200 Hz in frequency using this device. The general purpose of this experiment was to further understand information processing in the brain and how brain activity is…

1.0 Construction After the submarine cable has been designed inch-perfect, it is the next step where skills of geography are required. The construction of a submarine communications cable is not an easy matter. Furthermore, it is not an inexpensive job too. Skills and knowledge are required by engineers and workers whom are laying down the submarine communications cable. To ensure that the millions of dollars invested on the cable do not go to waste, every single precaution step must be taken…

New method of synthesis of oligoetherols with carbazole ring Renata Lubczak Abstract: The new method of synthesis of multifuntional oligoetherols with carbazole ring suitable for obtaining the polyurethane foams of enhanced thermal resistance was presented. At the first step of the synthesis the carbazole was reacted with excess glycidol to obtain the product of (n +1) functionality, where n is number of equivalents of glycidol reacted with carbazole. Carbazole reacts with glycidol without…
