Durango Bayfield Ignacio Southern Ute Greysill Mines La Plata Parrott City In its early years La Plata County leaned towards the Democratic Party. Only Benjamin Harrison in 1888, the three landslide victories of Theodore Roosevelt, Warren G. Harding and Herbert Hoover saw the county vote Republican before World War II. In the period between 1940 and 1988, the county – like Colorado – took a turn towards supporting the Republican Party, with the result that between 1940 and 2000 the only Democrat to obtain a majority in the county was Lyndon Johnson in 1964. Since John Kerry became the first candidate in sixteen years from either party to gain a majority in La Plata county in the 2004 election, the county has tended towards the Democratic Party: Barack Obama’s 2008 share of the vote was the highest for a Democrat since Woodrow Wilson's 92 years prior.

Dot (command)

In a Unix shell, the full stop called the dot command is a command that evaluates commands in a computer file in the current execution context. In C Shell, a similar functionality is provided as the source command, this name is seen in "extended" POSIX shells as well; the dot command is not to be confused with a dot file, a dot-prefixed hidden file or hidden directory. Nor is it to be confused with the./scriptfile notation for running commands, a relative path pointing to the current directory. The filename is the dot command's first argument; when this argument does not contain a slash, the shell will search for the file in all directories defined in the PATH environment variable. Unlike normal commands which are found in PATH, the file to source does not have to be executable. Otherwise the filename is considered as a simple path to the file. In several "extended" shells including bash and ksh, one may specify parameters in a second argument. If no parameters are specified, the sourced file will receive the set of positional parameters available in the current context.

If parameters are specified, the sourced file will receive only the specified parameters. In any case, parameter $0 will be the $0 of the current context. Since the execution of the source file is done in the invoking context, environment changed within apply to the current process or the current shell; this is different from scripts run directly by shebang or as sh, which are run in a new, separate process space, with a separate environment. Therefore, the dot command can be used for splitting a big script into smaller pieces enabling modular design. Sourcing is often done by the shell on session startup for user profile files like.bashrc and.profile. Source is a shell-builtin command that evaluates the file following the command, as a list of commands, executed in the current context; the "current context" is a terminal window into which the user is typing commands during an interactive session. The source command can be abbreviated as just a dot in similar POSIX-ish shells. However, this is not acceptable in C shell.

Some Bash scripts should be run using the source your-script syntax rather than run as an executable command, e.g. if they contain a change directory command and the user intends that they be left in that directory after the script is complete, or they contain an export command and the user wants to modify the environment of the current shell. Another usage situation is. Passing the script filename to the desired shell will run the script in a subshell, not the current context; the three different uses of the dot in Unix explained

Alexander Nevsky Cathedral, Novosibirsk

Alexander Nevsky Cathedral is the Eastern Orthodox Cathedral in Novosibirsk, named in honor of Saint Alexander Nevsky. It is one of the first stone constructions in Novonikolayevsk; the church was built in Neo-Byzantine architectural style in 1896–1899. The building design was influenced by the design of Church of Our Lady the Merciful in St. Petersburg built a few years earlier, it was opened and consecrated on December 29, 1899. In 1915 it became a cathedral; the cathedral was a specific monument to Tsar Alexander III who initiated construction of the Trans-Siberian Railway which resulted in foundation of Novonikolayevsk as a new railway station. In 1937, the cathedral was closed by Soviet authorities. In 1988, the year of the 1000th anniversary of Kievan Rus' conversion to Christianity, a movement began for the restitution of the cathedral. In 1989, it was re-opened. Neo-Byzantine architecture in the Russian Empire Alexander Nevsky Cathedral - other cathedrals of the same name Official website Людмила Кузменкина.

Von Neumann bicommutant theorem

In mathematics functional analysis, the von Neumann bicommutant theorem relates the closure of a set of bounded operators on a Hilbert space in certain topologies to the bicommutant of that set. In essence, it is a connection between the algebraic and topological sides of operator theory; the formal statement of the theorem is as follows: Von Neumann Bicommutant Theorem. Let M be an algebra of bounded operators on a Hilbert space H, containing the identity operator and closed under taking adjoints; the closures of M in the weak operator topology and the strong operator topology are equal, are in turn equal to the bicommutant M′′ of M. This algebra is the von Neumann algebra generated by M. There are several other topologies on the space of bounded operators, one can ask what are the *-algebras closed in these topologies. If M is closed in the norm topology it is a C*-algebra, but not a von Neumann algebra. One such example is the C*-algebra of compact operators. For most other common topologies the closed.

It is related to the Jacobson density theorem. Let H be a Hilbert space and L the bounded operators on H. Consider a self-adjoint unital subalgebra M of L; the theorem is equivalent to the combination of the following three statements: clW ⊆ M′′ clS ⊆ clW M′′ ⊆ clSwhere the W and S subscripts stand for closures in the weak and strong operator topologies, respectively. By definition of the weak operator topology, for any x and y in H, the map T → <Tx, y> is continuous in this topology. Therefore, for any operator O, so is the map T → ⟨ T x, O ∗ y ⟩ − ⟨ T O x, y ⟩ = ⟨ O T x, y ⟩ − ⟨ T O x, y ⟩. Let S be any subset of L, S′ its commutant. For any operator T not in S′, <OTx, y> - <TOx, y> is nonzero for some O in S and some x and y in H. By the continuity of the abovementioned mapping, there is an open neighborhood of T in the weak operator topology for which this is nonzero, therefore this open neighborhood is not in S′, thus S′ is closed in the weak operator, i.e. S′ is weakly closed, thus every commutant is weakly closed, so is M′′.

This follows directly from the weak operator topology being coarser than the strong operator topology: for every point x in clS, every open neighborhood of x in the weak operator topology is open in the strong operator topology and therefore contains a member of M. Fix X ∈ M′′. We will show X ∈ clS. Fix an open neighborhood U of X in the strong operator topology. By definition of the strong operator topology, U contains a finite intersection U ∩...∩U of subbasic open sets of the form U =, where h is in H and ε > 0. Fix h in H. Consider the closure cl of Mh = with respect to the norm of H and equipped with the inner product of H, it is a Hilbert space, so has a corresponding orthogonal projection which we denote P. P is bounded, so it is in L. Next we prove: Lemma. P ∈ M′. Proof. Fix x ∈ H. Px ∈ cl, so it is the limit of a sequence Onh with On in M for all n. For all T ∈ M, TOnh is in Mh and thus its limit is in cl. By continuity of T, this limit is TPx. Since TPx ∈ cl. From this it follows that PTP = TP for all T in M.

By using the closure of M under the adjoint we further have, for every T in M and all x, y ∈ H: ⟨ x, T P y ⟩ = ⟨ x, P T P y ⟩ = ⟨ P x, T P y ⟩ = ⟨ T ∗ P x, P y ⟩ = ⟨ P T ∗ P x, y ⟩ = ⟨ T ∗ P x, y ⟩ = ⟨ P x, T y ⟩ = ⟨ x, P T y ⟩ thus TP = PT and P lies in M′. By definition of the bicommutant XP = PX. Since M is unital, h ∈ Mh, hence Xh = XPh = PXh ∈ cl, thus for every ε > 0, there exists T in M with ||Xh − Th|| < ε. T lies in U, thus in every open neighborhood U of X in the strong operator topology there is a member of M, so X is in the strong operator topology closure of M. An algebra M acting on H is said to act non-degenerately if for h in H, Mh = implies h = 0. If M acts non-degenerately, is a sub C*-algebra of L, it can be shown using an approximate identity in M that the identity operator I lies in the strong closure of M. Therefore, the conclusion of the

Argyle Stores

The Argyle Stores is a heritage-listed former custom house and bond store that now serves as offices, function rooms and restaurant located at 12-20 Argyle Street in the inner city Sydney suburb of The Rocks in the City of Sydney local government area of New South Wales, Australia. The east wing was designed by Henry Cooper; the Argyle Stores were built from 1826 to 1878. It is known as Argyle Bond Stores and Cleland Bond Store; the property is owned by an agency of the Government of New South Wales. It was added to the New South Wales State Heritage Register on 10 May 2002; the first European development of the site was associated with the extension of Sydney's first Hospital, with the planting of herb and vegetable gardens on the bond store site. The first building was a house commenced by Captain John Piper in 1826 at what became the east wing of the current stores, who sold it before completion to Mary Reiby in 1828. Frederick Unwin bought it that year and completed the building in c. 1829.

Designed by architect Henry Cooper, the three level building had a dressed stone elevation to Argyle Street. Samuel Terry bought the site in 1831; the northern extension to the Customs House was completed by 1835. In 1839, Unwin again bought the site, work commenced on'Unwin's Bonded Stores'; these included an addition to the northern side of the Custom House and other buildings forming a courtyard in the middle. In 1826, construction of the East Wing was started under the supervision of Piper in his capacity as Naval Officer; as owner of the property, Piper sold the land and completed building to Mary Reiby in 1828, who in turn sold it to Frederick Unwin. In 1829 Unwin mortgaged the property and from 1830 the east wing was used as the "Custom House". Unwin regained ownership in 1838 and building construction resumed in 1839. Around 1844 goods such as brandy, tea, tobacco and sugar were stored. In 1845 the City Council Rates Book lists the Custom House as "two floors in bad repair", it was about this time.

The South wing appears to have remained vacant until c. 1835. The map of 1835 shows a small building at the extreme west end of the wing, it appears that this may have been built at the time Henry Fisher was "Custom House Agent", as the City Council Rate Book of 1845 lists this building as a house of three rooms, it may have been built as the residence for the "Custom House Agent". Three other small buildings had been built on the site when, in 1876, Isaac Ellis Ives bought the stores and began to expand their capacity. Part of this expansion involved the demolition of most of the existing south wing and the construction of a new wing c. 1878. The West wing of the stores was built between 1840-1845. In 1845 the City Council Rates Book lists the entire west wing as "new stores" of "4 floors", tenanted by Henry Fisher and owned by Frederick Unwin. In 1854 the stores were purchased by R & E Tooth and merchants who occupied the west and north wings. During this period the building was used as a free store.

There have been no major structural changes to the west wing. 1840. The original building on the site was a simple Georgian sandstone building roofed with slates, the first use of this roofing material in the colony; the numerous brick Victorian additions were made in the 19th century during various ownerships. Under the buildings solid sandstone cellars are covered by massive hand hewn timber beams whilst upper floors are in heavy timber post and beam construction; the roofs are simple hipped forms, now sheeted with corrugated iron. The courtyard is entered via passageways whose entrances are surrounded by articulated sandstone arches and quoins whilst the brick walls and pilasters to the streets are stuccoed; the building contains an important item located within the building. Completed in various stages, the Argyle Stores shows elements of Colonial Georgian, Victorian Warehouse, Art Nouveau Chicago architectural styles; the building has 3,4 storeys plus basement with a stone façade, timber floor and roof frames, with galvanised iron roof cladding.

Despite numerous alterations, the buildings retain much of the fabric of their major phases of development and use as commercial stores. Major developments include: c. 1878 -- East wing built. 1840-45 – West wing built. 1881 – North wing built. C. 1878 and 1968-69 – South wing built. Early 1970s – Conservation and adaptation work was undertaken for conversion of the store for an antique market and other businesses of an art and craft theme. 1993 – The SCA obtained vacant possession of the Argyle Centre, to enable a major refurbishment and fit out of the Stores by architects Allen Jack+Cottier. The existing fitout was removed to create open floor space to all levels. November 1995 – The Centre was reopened. 1996-7 – Additional air conditioning was provided to the buildings. 2006-07 – The building and courtyard were refurbished and the Hydraulic whip restored. As at 30 March 2011, the Argyle Stores and site are of State heritage significance for their historical and scientific cultural values; the site and building are of State heritage significance for their contribution to The Rocks area, of State Heritage significance in its own right.

The listings in the registers of both the National Trust and the National Estate demonstrate the esteem the Stores are held in by the wider community. The Argyle Stores include substantial remains of one the earliest surviving commercial buildings in Sydney, dating from c. 1826. The complex contains the earliest surviving building occupied for use as a Customs House from 1830 until 1850. Despite numerous alterations, the buildings retain much of

Area Support Unit Chilliwack

Area Support Unit Chilliwack is a Canadian Forces facility located in Chilliwack, British Columbia. Located in the upper valley of the Fraser River 100 km east of Vancouver, it is the only Land Force Command facility in the province, it provides essential support and services for 200 Regular 1800 Reserve Force personnel. The mission of ASU Chilliwack is to provide direct support for all its assigned dependencies by providing logistical support and maintenance; the unit badge depicts the Rocky Mountains and the Pacific Ocean, which form the east and west boundaries of the unit's area of operations, respectively. This concept is further illustrated by the unit motto Ad Mare Usque Mons, which translates to "From Sea to Mountain". Military presence in the region is thought to have begun with the Royal Engineers who established a camp at Sumas near Chilliwack Mountain in 1858. From the camp, they conducted surveys and established boundary markers along the border to the south. Camp Chilliwack was opened on 15 February 1941, as part of a government decision to establish a military training facility in the region.

It served as a garrison for several army units, formed for terrestrial defence. In 1966, Camp Chilliwack was renamed to Canadian Forces Base Chilliwack as part of the Canadian Forces unification program. Along with the change in name, CFB Chilliwack assumed additional responsibilities, such as providing support to all of the CF units on the lower mainland and assuming responsibility for the Jericho Beach Garrison in Vancouver. In 1970, Canadian Forces Officer Candidate School was established at CFB Chilliwack and offered a tri-service Basic Officer Training Course. In 1994, the 3rd Princess Patricia's Canadian Light Infantry moved from CFB Esquimalt on Vancouver Island to CFB Chilliwack. Due to budget cuts, CFB Chilliwack was closed in 1997 and new bases were found for the units located at the former CFB Chilliwack; the Canadian Forces Officer Candidate School was moved to St-Jean, the Canadian Forces School of Military Engineering was moved to CFB Gagetown, New Brunswick, 3PPCLI moved to CFB Edmonton, Alberta.

Because of the closure of CFB Chilliwack, a need arose for a supporting formation to provide area-wide support for the Canadian Forces units remaining in mainland BC. In response to this need, 1 Area Support Group was created in 1999. On 4 February 1999, ASU Chilliwack was formed and allocated as a unit within the 1ASG. ASU Chilliwack supports the following Canadian Forces units on the British Columbia Mainland: 39 Canadian Brigade Group The British Columbia Regiment The British Columbia Dragoons 39 Combat Engineer Regiment The Seaforth Highlanders of Canada The Rocky Mountain Rangers The Royal Westminster Regiment 15th Field Regiment, Royal Canadian Artillery 39 Signal Regiment 39 Service Battalion 12 Service Company 6 Intelligence Company, Detachment Vancouver 12 Field Ambulance 12 Military Police Platoon HMCS Discovery 192 Construction Engineering Flight Canadian Forces Recruiting Centre National Defence Quality Assurance Region National Defence Public Affairs University Liaison Office Regional Cadet Support Unit ASU Chilliwack has responsibility over several military training areas.

These areas are used by Regular Force units from 1 Canadian Mechanized Brigade Group, Reserve Force units from Mainland British Columbia, some units training for deployment to Afghanistan, as well as Cadets. ASU Chilliwack maintains ranges and training areas for use by it dependencies, as well as visiting units.
