180 L. TRUMPF had success with this product and decided to make their own CO2 laser machine. This led to the development and manufacture of the TRUMPF LASER TLF 1000. It had a 1kW of beam power and was the first machine to include a compact laser resonator with RF excitation. This combination of the accuracy of laser cutting along with the existing numerical control capability of its machine-tools, TRUMPF revolutionized the sheet metal fabrication industry. TRUMPF continued to focus on its…

Gustavo Oliveira Coutinho, 4º ano Class: 4BTEL Innovate Tesla: the resurgence of Nikola Tesla from oblivion to spotlight Introduction Nikola Tesla is one of the most controversial figures on science. While many judged him simply as a mad scientist, few were able to see how he was ahead of his own time, providing the theoretical and practical foundation to several modern equipments. We, as a society, not only owe Tesla for the AC (alternating current) electric system of supply, but…

1. Redox Catalyst Catalyst is defined as a substance that increases the rate of a chemical reaction without changing its chemical composition and affecting the standard Gibbs free energy, by lowering the activation energy of a chemical reaction. It does so by providing an alternative reaction pathway. In redox reaction, the key chemical event is the net movement of electrons from one reactant to the other. The oxidation state of atoms are changed. Transition metal is used as redox catalyst due…

Native American Album Many years ago, the Native Americans, also referred to as indigenous people, came up with the idea of creating music for specific ideas and situations. Their music included multiple man-made instruments in which easily could produce sound to create a musical note. A popular and well known artist is, R. Carlos Nakai, who distinguishes himself as a Native American flutist. Nakai has released multiple albums throughout the time he has been playing the flute professionally; one…

I chose Brazil for my term paper because I have always been secretly fascinated with the mysterious name, “Brazil,” the culture, the accents, the music and dance. I learned a few things that I did not know prior to the research such as the connection between Brazil and African slaves. I grew up believing everyone in Latin America was only Latin just like I thought all Europeans were only white until visiting and there were Africans there as well. I also learned that the Samba was not the…

Computers and Craniums: A Continuing Cycle of Connections The enigma of the human mind is a puzzle that has fascinated many great scientists. From the earliest musings of the ancient philosophers to the advanced neuroscience research going on today, many intelligent people have worked to understand what is going on in our own heads. In an interesting phenomenon, our understanding of the mind is intimately linked to the technology that is used to study it, and the new findings that arise feed…

That iconic piece of equipment that hangs around all physicians necks that gives them a professional aura. We all know what this is, it’s the stethoscope. Have you ever wondered how doctors listened to their patients lungs and heart before the stethoscope was invented? How they made accurate diagnosis without the essential stethoscope all healthcare workers use today? Before the early 1800’s physicians didn’t have a tool to do this. They would place their ear next to the patient's chest and…

"Could Frankenstein learn to talk without Human interaction" When a child grows up, it goes through various speaking phases. At the beginning it starts with " goo goo" and " gaa gaa" and later it is able to say actual words. Frankenstein's monster could possibly learn how to speak the same way a child does. Thanks to the understanding of language acquisition, there is a possibility that the monster could have an actual conversation with anyone. Taking into consideration language acquisition,…

the resonances created as air travels from the lungs, past the vocal folds, and out the lips to produce melody. Normally, this is performed by two females, who sit or stand face to face and create rhythmic patterns using each other’s ' mouths as resonators. No other tribe in the world does it the same as them and yet they are grouped together in a category with numerous other tribes. Preservation of Native American music traditions has proved to be extremely difficult for a myriad of reasons.…

The primary test showing of an association between naturally visible piezoelectric marvels and crystallographic structure was distributed in 1880 by Pierre and Jacques Curie. Their analysis comprised of a decisive estimation of surface charges showing up on extraordinarily arranged precious stones (tourmaline, quartz, topaz, natural sweetener and Rochelle salt among them) which were subjected to mechanical anxiety. These outcomes were a sound representative for the Curies ' creative ability and…
