# Federal Office Building (Omaha, Nebraska)

The Federal Office Building (Omaha, Nebraska), also known as the Old Federal Building, is a thirteen story, stripped classical style building with Art Deco elements located in downtown Omaha, Nebraska. The building was designed and built in 1933-34 by architects Thomas R. Kimball, William L. Steele, and Josiah D. Sandham as part of the firm Kimball, Steele & Sandham, plus associated architect George B. Prinz. It was built on the site of first U.S Courthouse and Post Office.
Part of the New Deal building program, the structure's original occupants were all federal agencies including the US Weather Bureau, the Internal Revenue Service (IRS), the Department of Agriculture, Civil Service Commission, Customs Service, Army, and Navy. The federal District Court for Nebraska met here until the late 1950s or early 1960s. The US Army Corps of Engineers was the last federal agency officed here, and subsequent to their departure in July 2008, it has not been in use by the federal government. In 1995, the building was allegedly examined as a target by Timothy McVeigh prior to his involvement in the Oklahoma City Bombing, although this fact was not substantiated by the FBI.
In December 2011, the building was sold to developers who planned on turning it into a 152-room Residence Inn by Marriott. The $23 million project was expected to be completed by 2013, and opened to guests in October 2013. In order to keep the building on the NRHP, the exterior facade remains the same, as do some of the original interior features, such as terrazzo marble floors.
# List of World Heritage Sites in Qatar

The United Nations Educational, Scientific and Cultural Organization (UNESCO) World Heritage Sites are places of importance to cultural or natural heritage as described in the UNESCO World Heritage Convention, established in 1972. Qatar accepted the convention on September 12, 1984, making its historical sites eligible for inclusion on the list. As of 2023, Qatar has only one World Heritage Site, Al Zubara Fort, which was inscribed in 2013.

Founded by merchants from Kuwait, Al Zubarah had trading links across the Indian Ocean, Arabia and Western Asia. A layer of sand blown from the desert has protected the remains of the site’s palaces, mosques, streets, courtyard houses, and fishermen’s huts; its harbour and double defensive walls, a canal, walls, and cemeteries. Excavation has only taken place over a small part of the site, which offers an outstanding testimony to an urban trading and pearl-diving tradition which sustained the region’s major coastal towns and led to the development of small independent states that flourished outside the control of the Ottoman, European, and Persian empires and eventually led to the emergence of modern day Gulf States. |

## Reception

Professional ratings :
| Review scores ||
| Source | Rating |
| AllMusic | |
| Metal Storm | 7.5/10 |
| Rock Hard | 6/10 |
AllMusic reviewer Alex Henderson stated that, while the album was not "essential", it was "a solid and well-executed effort" by the band, singling out "Breathe Again", "Monster", "A War Never Won" and "Company of Sorrow" in particular as standout tracks on the album. Metal Storm reviewer found the album solid and "extremely pleasant but not sensational", because Metal Church did not "take any risk with this new release" and kept the songs "really simple and not original." Exclaim! reviewer Keith Carman praised Ronny Munroe's performance which he compared to Bruce Dickinson's, but found the music old-fashioned and "mired in more crooning, stock riffs and mid-tempo beats than anything truly engaging", concluding that "This Present Wasteland is a fitting moniker for a band living off nostalgia more than current ability." Rock Hard reviewer called the current line-up "only a shadow of the aggressive quintet of the past" and remarked the scarce originality of the compositions and the pessimistic mood of the album.

# Uncle Am Stuart

Ambrose Gaines "Uncle Am" Stuart (1853–1926) was an American Old-time fiddle player. After winning various fiddle contests across the Southern Appalachian region in the late 19th and early 20th centuries, Stuart made several recordings in June 1924 that would later prove influential in the development of early Country music.
Stuart was born near Morristown, Tennessee in 1853. He learned to play fiddle at a young age, picking up a number of tunes from Civil War soldiers who passed through the area in the 1860s, and learning techniques while wandering through post-Civil War African-American camps. His later style represented a fusion of Civil War tunes and Appalachian folk music. By the time he had gained regional fame as a fiddle player in the early 1900s, Stuart was working as a safe and vault salesman.
Noting the success of the Okeh recordings of Fiddlin' John Carson in 1923, Vocalion Records sought to recruit its own Southern mountain musicians, and the following year invited several Southern Appalachian musicians to New York to record, among them Uncle Am Stuart. The 14 sides Stuart recorded included the first known recordings of the Appalachian folk songs Cumberland Gap and "Forked Deer," early renditions of the oft-played fiddle tunes "Grey Eagle" and "Old Granny Rattletrap," and early renderings of later bluegrass staples "Sallie Gooden" and "Old Liza Jane."
In 1925, Stuart attended the Fiddlers' Convention in Mountain City, Tennessee, where he competed in a now-legendary fiddle contest against rival fiddlers such as Charlie Bowman, G. B. Grayson, Dudley Vance, and Fiddlin' John Carson. Accounts vary as to the contest's results, although at least one account placed Stuart in third place. In the early 1930s, Stuart's Vocalion recordings were among those a young Roy Acuff sought to emulate while learning to play the fiddle.

# Ferrocarril Sonora–Baja California

The Ferrocarril Sonora–Baja California is a former railroad line of Mexico that built the line from Mexicali, Baja California, to Benjamín Hill, Sonora in 1948. It interchanged with the Southern Pacific Railroad at Calexico, California, and with the Ferrocarril del Pacifico in Benjamin Hill, Sonora. Before 1960, The SP-controlled Inter-California railroad provided trackage rights for the SBC from Pascualitos to the International Border. SBC took control of that part after the demise of the Inter-Cal.
SBC provided passenger and freight service throughout its existence. It was headquartered in Mexicali, B.C. and had major repair and overhaul shops for its equipment in the town of Benjamin Hill, Sonora. From 1970 into the FNM merger, the SBC also controlled the 44-mile freight-only "Ferrocarril Tijuana y Tecate" UB line from border to border. SP, Kyle Railways and later the San Diego and Imperial Valley Railroad operated the line, paying a fee to the SBC, and later to FNM.
It was absorbed into Nacionales de México in 1987, thus becoming a fallen-flag. The last passenger train from Mexicali to Benjamin Hill operated in 1997. Today the line continues to provide daily modern freight service, including intermodal. It is now known as Ferromex's Puerto Penasco Subdivision and designated by the SCT as the "U" and "UA" lines of the Mexican rail system.

# Felice Varini

* Felice Varini Gallery
* 5 Open Ellipses. Urban painting of Felice Varini, in Metz, 2009
* Nine dancing triangles - by Felice Varini, France, 2012
Felice Varini (born in Locarno in 1952) is a Paris-based, Swiss artist who was nominated for the 2000/2001 Marcel Duchamp Prize. Mostly known for his geometric perspective-localized paintings in rooms and other spaces, using projector-stencil techniques, according to mathematics professor and art critic Joël Koskas, "A work of Varini is an anti-Mona Lisa."

## Style

Felice paints on architectural and urban spaces, such as buildings, walls and streets. The paintings are characterized by one vantage point from which the viewer can see the complete painting (usually a simple geometric shape such as circle, square, line), while from other viewpoints the viewer will see 'broken' fragmented shapes. Varini argues that the work exists as a whole - with its complete shape as well as the fragments. "My concern," he says "is what happens outside the vantage point of view."

## Carcassonne 2018

In May 2018, Varini's project "Concentric, eccentric" saw large yellow concentric circles mounted on the monument at Carcassonne as part of the 7th edition of "IN SITU, Heritage and contemporary art", a summer event in the Occitanie / Pyrenees-Mediterranean region focusing on the relationship between modern art and architectural heritage. This monumental work was to celebrate the 20th anniversary of Carcassonne's inscription on the World Heritage List of UNESCO. Exceptional in its size, visibility and use of architectural space, the exhibit extended on the western front of the fortifications of the city. The work could only be fully perceived in front of the Porte d'Aude at the pedestrian route from the Bastide. The circles of yellow colour consist of thin, painted aluminium sheets, spread like waves of time and space, fragmenting and recomposing the geometry of the circles on the towers and curtain walls of the fortifications. The work should have remained visible from May to September 2018 only, but it left traces still present today.

## Disc 2011

The Lyon Confluence project was a major urban development carried out in France. The exhibition in 2011, presented the complete architectural vision, using the help of photographs, models, drawings, 3D digital images, and films, for the City of Architecture and Heritage. The museographic space of the Lyon Confluence exhibition was a Renaissance laboratory. On the ceiling, Red square hollowed out by Felice Varini's "Disc", 2011.
