Polish American Heritage Month is an annual event celebrated in October by Polish American communities.
 It was first celebrated in 1981 after organization by Michael Blichasz, President of the Polish American Cultural Center in Philadelphia.
 Originally it was celebrated in August at various gatherings, travel events, and culturally-significant locations in Pennsylvania.
 The Polish American Cultural Center and the Polish American Congress lobbied politicians at the state and national level to make August the month for Polish heritage.
 In 1984, House Joint Resolution 577 passed, making August Polish American Heritage Month.
 President Ronald Reagan urged all Americans to join in the celebration honoring Polish heritage in the United States.
 The month was changed to October in 1986 to aid participating schools in organization during the school year, and October holds significance as the month when the first Polish settlers came to Jamestown, Virginia.
Nuts and Volts is a monthly American magazine for the hands-on hobbyist, design engineer, technician, and experimenter.
 It has been published by T&L Publications since 1980 and leans heavily toward microcontroller and digital electronics projects.
 The magazine is based in Corona, California.
On August 3, 1990 President of the United States George H. W. Bush declared the month of November as National American Indian Heritage Month, thereafter commonly referred to as Native American Heritage Month.
 First sponsor of "American Indian Heritage Month" was through the American Indian Heritage Foundation by the founder Pale Moon Rose, of Cherokee-Seneca descent and an adopted Ojibwa, whose Indian name Win-yan-sa-han-wi "Princess of the Pale Moon" was given to her by Alfred Michael "Chief" Venne
Horizon was a magazine published in the United States from 1958 to 1989.
 Originally published by "American Heritage" as a bi-monthly hardback, "Horizon" was subtitled "A Magazine of the Arts".
 In 1978, Boone Inc. bought the magazine, which continued to cover the arts.
 Publication ceased in March 1989.
 Recently, American Heritage announced its intention to digitize essays from past issues.
Before the Folsom powerhouse was built nearly all electric power houses were using direct current (DC) generators powered by steam engines located within a very few miles of where the power was needed.
 The use of rushing water to generate hydroelectric power and then transmitting it long distances to where it could be used was not initially economically feasible as long as the electricity generated was low-voltage direct current.
 Once it was invented, AC power made it feasible to convert the electrical power to high voltage by using the newly invented transformers and to then economically transmit the power long distances to where it was needed.
 Lower voltage electrical power, which is much easier and safer to use, could be easily gotten by using transformers to convert the high voltage power to lower voltages near where it was being used.
 DC power cannot use a transformer to change its voltage.
 The Folsom Powerhouse, using part of the American River's rushing water to power its turbines connected to newly invented AC generators, generated three phase 60 cycle AC electricity (the same that's used today in the United States) that was boosted by newly invented transformers from 800 volts as generated to 11,000 volts and transmitted to Sacramento over a 22 mi (35 km)-long distribution line, one of the longest electrical distribution lines in the United States at the time.
American Heritage is a magazine dedicated to covering the history of the United States of America for a mainstream readership.
 Until 2007, the magazine was published by Forbes.
 Since that time, Edwin S. Grosvenor has been its publisher.
 Print publication was suspended early in 2013, but the magazine relaunched in digital format with the Summer 2017 issue after a Kickstarter campaign raised $31,203 from 587 backers.
 The publisher stated it also intended to relaunch the magazine's sister publication "Invention & Technology", which ceased print publication in 2011.
American Heritage of Invention & Technology was a quarterly magazine dedicated to the history of technology.
 It was a spinoff of "American Heritage" magazine.
 It started in the summer of 1985 and there were three issues a year until 1992, when it became quarterly.
 Following the Summer 2007 issue (volume 23, number 1), publication was suspended (along with "American Heritage" itself).
 Publication of the magazine resumed with the Summer 2008 issue (volume 23, number 2), under the slightly changed title American Heritage's Invention & Technology.
 The last issue was Winter 2011 (volume 25, number 4).
The Asian Pacific American Heritage Festival, hosted by the Coalition of Asian Pacific Americans in New York City, is one of the largest outdoors celebrations of Asian Pacific American Heritage Month in the United States.
 Each year, in May, the festival offers music, performances, arts, food, history and corporate outreach.
 The first festival in 1979 grew out of the civil rights movements of that era when President Jimmy Carter signed the proclamation to declare the first week in May to be Asian American Heritage Week.
 The proclamation was later extended to Asian Pacific American Heritage Month for the entire month of May.
 The festival has continued every year to celebrate the diverse cultures of Asian Americans and their contribution to American society.
 It has become so large that it takes the Coalition all year to put together.
