Deerfield Beach, Florida
Deerfield Beach is a city in Broward County, Florida, United States, just south of the Palm Beach County line. The city is named for the numerous deer that once roamed the area. As of the 2020 census, the population was 86,859. It is a principal city of the Miami metropolitan area, which is home to 6,166,488 inhabitants as of 2020. History Deerfield Beach's history dates to 1890, when a small settlement named Hillsborough was developed along the Hillsboro River. As the population grew to 20 by 1898, the settlement was now served by its own post office and the town was named Deerfield for the deer that grazed along the river. By the early 20th century, as the town's population continued to grow, the Florida East Coast Railroad constructed tracks en route to Miami bisecting Deerfield. Deerfield's early settlers were mostly farmers who grew pineapples, tomatoes, green beans, squash and fished along the Intracoastal Waterway. Deerfield remained a largely agricultural community, but ...

Decafluorobutane
Perfluorobutane (PFB) is an inert, high-density colorless gas. It is a simple fluorocarbon with a ''n''-butane skeleton and all the hydrogen atoms replaced with fluorine atoms. Uses Perfluorobutane can replace Halon 1301 in fire extinguishers, as well as the gas component for newer generation microbubble ultrasound contrast agents. Sonazoid is one such microbubble formulation developed by Amersham Health that uses perfluorobutane for the gas core. Inhaling perfluorobutane makes one's voice deeper. Environmental impacts If perfluorobutane is released to the environment, it will not be broken down in air. It is not expected to be broken down by sunlight. It will move into air from soil and water surfaces. If it is exposed to conditions of extreme heat from misuse, equipment failure, etc., toxic decomposition products including hydrogen fluoride can be produced. Perfluorobutane has an estimated lifetime greater than 2600 years. Perfluorobutane has a high global warming potential ...

Dem Franchize Boyz
Dem Franchize Boyz was an American hip hop group from Atlanta, signed to E1 Music. The group had four members: Parlae (born Maurice Gleaton), Pimpin' (Jamal Willingham), Jizzal Man (Bernard Leverette), and Buddie (Gerald Tiller). They were best known for their hit singles "I Think They Like Me" and "Lean wit It, Rock wit It". History The origin of the group dates back to when all four members were high school and college school mates, making music for fun while furthering their education. In regards to the group name, Parlae stated that "We are a franchise, a business. We're homeboys, but we're business partners too. We all do different things and have different roles. That's how we got the name." One day while pursuing their business degrees in North Carolina, the four recorded a song in a dorm room that would become their future debut and hit single "White Tee," before moving back to Atlanta. The group signed to Universal Records in 2004 after performing unsigned. Universal r ...

Humid Continental Climate
A humid continental climate is a climatic region defined by Russo-German climatologist Wladimir Köppen in 1900, typified by four distinct seasons and large seasonal temperature differences, with warm to hot (and often humid) summers and freezing cold (sometimes severely cold in the northern areas) winters. Precipitation is usually distributed throughout the year but often do have dry seasons. The definition of this climate regarding temperature is as follows: the mean temperature of the coldest month must be below or depending on the isotherm, and there must be at least four months whose mean temperatures are at or above . In addition, the location in question must not be semi-arid or arid. The cooler ''Dfb'', ''Dwb'', and ''Dsb'' subtypes are also known as hemiboreal climates. Humid continental climates are generally found between latitudes 30° N and 60° N, within the central and northeastern portions of North America, Europe, and Asia. They are rare and isolat ...

Distributed-feedback Laser
A distributed-feedback laser (DFB) is a type of laser diode, quantum-cascade laser or optical-fiber laser where the active region of the device contains a periodically structured element or diffraction grating. The structure builds a one-dimensional interference grating (Bragg scattering), and the grating provides optical feedback for the laser. This longitudinal diffraction grating has periodic changes in refractive index that cause reflection back into the cavity. The periodic change can be either in the real part of the refractive index or in the imaginary part (gain or absorption). The strongest grating operates in the first order, where the periodicity is one-half wave, and the light is reflected backwards. DFB lasers tend to be much more stable than Fabry–Perot or DBR lasers and are used frequently when clean single-mode operation is needed, especially in high-speed fiber-optic telecommunications. Semiconductor DFB lasers in the lowest loss window of optical fibers at abou ...

Dublin Fire Brigade
The Dublin Fire Brigade (DFB; ga, Briogáid Dóiteáin Átha Cliath) is the local authority fire service, fire and rescue service and ambulance service for Dublin, Dublin City and the majority of the Greater Dublin Area. It is a branch of Dublin City Council. There are currently 14 fire stations staffed by DFB, 12 of which are full-time, the other 2 are part-time or "retained". Full-time stations are staffed by shifts across 4 watches, A, B, C & D. There are currently over 1000 active firefighter/paramedic personnel making it the largest fire service based on personnel and resources in Republic of Ireland, Ireland. History Dublin City's first municipal fire engines were delivered in 1705. Throughout the second half of the 18th Century, insurance brigades were the primary source of firefighting for the city, operating independently for buildings bearing the mark of their respective insurance companies. Eventually the brigades began to co-operate on a competition basis with th ...

Dysfunctional Family BBQ
K-Rockathon was an annual music festival held in the Central New York region of New York sponsored by Galaxy Communications-owned radio stations WKLL/WKRL-FM/WKRH. These concerts were held at venues in Vernon, Syracuse, Oswego, Utica, and Weedsport, NY. Local bands are showcased at the event along with nationally-touring rock music acts. K-Rockathon has showcased many subgenres of rock music from alternative rock, to rap rock, to straight metal and drew hundreds of thousands to Central New York over its twenty year run. History The inaugural K-Rockathon was held on July 28, 1996, at the Vernon Downs race track in Vernon, NY. This was the same location through 1999, after which the event moved to the New York State Fairgrounds in Syracuse, New York Syracuse ( ) is a City (New York), city in and the county seat of Onondaga County, New York, Onondaga County, New York, United States.

Furka Steam Railway
The Furka Steam Railway (german: Dampfbahn Furka-Bergstrecke (DFB)) is a largely volunteer-operated heritage railway which operates a partially rack and pinion-operated line across the Furka Pass, between Realp in Canton of Uri, Uri and Oberwald in Valais. Culminating at , above sea level, it is an old mountainous section of the Furka Oberalp Bahn (FO) that was abandoned after the construction of the Furka Base Tunnel, Furka Tunnel. It has been gradually brought back into service by the Verein Furka-Bergstrecke with the use of only steam locomotives, with the entire line completed in 2010. As a result, the nearly 18 kilometre-long Furka Railway is the longest operated unelectrified line in Switzerland. It is also the List of highest railways in Europe, second highest rail crossing in Europe, after the Bernina Railway. The Uri side of the line also constitutes the highest railway in Central Switzerland. The section of line was always a severe operational difficulty for the FO as ...
