A spring is an elastic object used to store mechanical energy. Springs are usually made out of spring steel. There are a large number of spring designs; in everyday usage the term often refers to coil springs.
Small springs can be wound from pre-hardened stock, while larger ones are made from annealed steel and hardened after fabrication. Some non-ferrous metals are also used including phosphor bronze and titanium for parts requiring corrosion resistance and beryllium copper for springs carrying electrical current (because of its low electrical resistance).
When a coil spring is compressed or stretched slightly from rest, the force it exerts is approximately proportional to its change in length (this approximation breaks down for larger deflections). The rate or spring constant of a spring is the change in the force it exerts, divided by the change in deflection of the spring. That is, it is the gradient of the force versus deflection curve. An extension or compression spring has units of force divided by distance, for example lbf/in or N/m. Torsion springs have units of torque divided by angle, such as N·m/rad or ft·lbf/degree. The inverse of spring rate is compliance, that is: if a spring has a rate of 10 N/mm, it has a compliance of 0.1 mm/N. The stiffness (or rate) of springs in parallel is additive, as is the compliance of springs in series.

Enterprise (formerly, Mountain Spring) is a former settlement in Butte County, California. It was located 5 miles (8.0 km) west-northwest of Forbestown on the South Fork of the Feather River, at an elevation of 902 feet (275 m). In 1968, it was inundated by Lake Oroville.
A post office operated at Enterprise from 1878 to 1926, with a brief closure in 1903. The town was founded in 1852 as Mountain Spring and used as a construction camp. Its later economy was based on being a supply center for the mining operations nearby, especially near Bidwell's Bar. The mining town of Yankee Flat was located 5 miles (8.0 km) southeast of Enterprise.
INDICAZIONI GENERALI: Il dispositivo "Spring Device" è indicato in: 1. Difficoltà di apertura della mandibola (trisma o ipomobilità) perché induce l'allungamento dei tessuti connettivi mobilitando le articolazioni e allungando interamente i muscoli. 2. Presenza di bruxismo e/o serramento dentale. 3. Riduce il dolore e l'infiammazione dei muscoli e dell'articolazione stessa, riducendone il gonfiore. 4. La mobilitazione dell'articolazione indotta dal dispositivo ha effetti benefici nei disturbi articolari. Il movimento è necessario per prevenire la degenerazione della cartilagine, lo strato tissutale che riveste la maggior parte delle superfici articolari. 5. Caso di necessità di registrare un rapporto tra le arcate dentali; 6. Applicazione di forze asimmetriche (es. estrazioni dentali); 7....

Brunelli e Tonlorenzi spiegano che le reazioni più drammatiche indotte dal nervo trigemino hanno origine da brusche stimolazioni (es. forti dolori o improvvisi sbalzi nella temperatura), con un riflesso noto da tempo come riflesso trigeminale. Il problema era riuscire a regolare l'intensità di questo riflesso, in modo da regolare anche l'intensità delle reazioni indotte. Per ottenere questo risultato Tonlorenzi e Brunelli hanno pensato di usare stimolo interno al corpo, cioè un allungamento dei muscoli della masticazione: in pratica, uno stretching. Sulla domanda "esiste un riflesso trigemino-cardiaco indotto da stretching mandibolare?" è nato un fermento che coinvolge molte università italiane (Pisa, Perugia, Siena, Napoli, Firenze, Chieti) ed estere ed un forte lavoro sul campo per valu...

According to multiple accounts, the Black Knight Satellite has been transmitting radio signals for as long as we've been able to recognize the fact. The US and Soviet Union have shown particular interest in this “unidentified space object” Rumors are that it was Nikola Tesla the first man to “intercept” a signal from the black knight satellite in 1899 after building a high-voltage radio device in Colorado Springs. Since the 1930′s Astronomers worldwide have been reporting strange radio signals which allegedly come from the “Black Knight”. In 1957, Dr. Luis Corralos of the Communications Ministry in Venezuela photographed it while taking pictures of Sputnik II as it passed over Caracas. The story of the Black Knight made its media debut in the 1940′s when the St. Louis Dispatch and The...

Tesla's Life - Nikola Tesla New Documentary - Nikola Tesla (Serbian Cyrillic: Никола Тесла; 10 July 1856 – 7 January 1943) was a Serbian American[3][4][5][6] inventor, electrical engineer, mechanical engineer, physicist, and futurist best known for his contributions to the design of the modern alternating current (AC) electricity supply system.[7] Tesla gained experience in telephony and electrical engineering before emigrating to the United States in 1884 to work for Thomas Edison in New York City. He soon struck out on his own with financial backers, setting up laboratories and companies to develop a range of electrical devices. His patented AC induction motor and transformer were licensed by George Westinghouse, who also hired Tesla for a short time as a consultant. His work in th...
