The Imhoff tank, named for German engineer Karl Imhoff (1876–1965), is a chamber suitable for the reception and processing of sewage.
 It may be used for the clarification of sewage by simple settling and sedimentation, along with anaerobic digestion of the extracted sludge.
 It consists of an upper chamber in which sedimentation takes place, from which collected solids slide down inclined bottom slopes to an entrance into a lower chamber in which the sludge is collected and digested.
 The two chambers are otherwise unconnected, with sewage flowing only through the upper sedimentation chamber and no flow of sewage in the lower digestion chamber.
 The lower chamber requires separate biogas vents and pipes for the removal of digested sludge, typically after 6-9 months of digestion.
 The Imhoff tank is in effect a two-story septic tank and retains the septic tank's simplicity while eliminating many of its drawbacks, which largely result from the mixing of fresh sewage and septic sludge in the same chamber.
The National Assembly is bicameral with the lower house, the Chamber of Deputies, having 40 members elected in single-seat constituencies for a four-year term.
 The upper house, the Shura Council, has 40 members appointed by the King of Bahrain, with the stated aim of giving a voice to minority communities and technocratic experts within the legislative process.
 Supporters of the system refer to long established democracies the United Kingdom and Canada operating with this bicameralism with an appointed upper chamber and an elected lower chamber.
 Opponents of this system point out that unlike the bicameral systems in the UK and Canada, the Bahraini system gives the unelected upper house equal or more legislative power than the elected lower house, allowing the King to control all legislation.
 Opponents also point out that the current system was imposed unilaterally by the King, violating the and a 2001 signed agreement with the Bahraini opposition.
The Congress of the Philippines (Filipino: "Kongreso ng Pilipinas" ) is the national legislature of the Philippines.
 It is a bicameral body consisting of the Senate (upper chamber), and the House of Representatives (lower chamber) although commonly in the Philippines the term congress refers to the latter.
The establishment of LGBT rights in the District of Columbia is a relatively recent occurrence, with the majority of advances in LGBT rights taking place in the past century.
 Along with the rest of the country, the District of Columbia recognizes marriage of same-sex couples.
 The percentage of households in the District of Columbia based on same-sex couples in 2008 was at 1.8%, the highest in the nation.
 Under the District of Columbia Home Rule Act 1973, all laws passed by the Council of the District of Columbia and signed by the Mayor of the District of Columbia, are subject to a mandatory 30-day "Congressional review" by US Congress.
 Only then after the 30-day Congressional review, the US Congress formally approves that law — then they become effective in the District of Columbia.
William Preston Taulbee (October 22, 1851 – March 11, 1890) was a U.S. Representative from Kentucky.
The Minnesota Territorial Legislature was a bicameral legislative body created by the United States Congress in 1849 as the legislative branch of the government of the Territory of Minnesota.
 The upper chamber, the Council, and the lower chamber, the House of Representatives, first convened on September 3, 1849.
 The two chambers served as the territory's legislative body until Minnesota was admitted as a state on May 11, 1858, when the Territorial Legislature was replaced by the Minnesota Legislature.
The Medicare Payment Advisory Commission (MedPAC) is an independent US federal body.
 MedPAC was established by the Balanced Budget Act of 1997 (P.L. 105-33).
 The Commission's 17 members bring diverse expertise in the financing and delivery of health care services.
 Commissioners are appointed to three-year terms (subject to renewal) by the Comptroller General of the United States and serve part-time.
 Its primary role is to advise the US Congress on issues affecting the administration of the Medicare program.
 Specifically the commission's mandate is to advise the US Congress on payments to private health plans participating in Medicare and health providers serving Medicare beneficiaries.
 MedPAC is also relied on by Medicare administrators and policy makers to evaluate beneficiary's access to care and the quality of care received.
 MedPAC's mandate is broad enough that it can also evaluate other issues affecting Medicare.
The United States House of Representatives is the lower chamber of the United States Congress, which along with the Senate composes the legislature of the United States.
The Speaker of the Chamber of Counties (Croatian: "Predsjednik Županijskog doma Hrvatskog sabora" , literally the President of the Chamber of Counties of the Croatian Parliament) was the presiding officer of the Chamber of Counties, the upper chamber of the Croatian Parliament from 22 March 1993 until its abolition by constitution changes on 28 March 2001.
 The Speaker of the Chamber of Counties was elected by a majority of the chamber's members for the duration of the parliamentary term.
 In the event of a dissolution of the chamber, the speaker would continue to serve until the inauguration of his or her successor.
 Only two individuals held the office of Speaker of the Chamber of Counties during its eight-year existence: Josip Manolić (1993–1994) and Katica Ivanišević (1994–2001).
 Katica Ivanišević remains the only woman to have served as Speaker of either chamber of Croatian Parliament.
 The office became defunct upon the passing of constitutional amendments by which the Chamber of Counties was abolished and the bicameral Croatian Parliament was replaced by a unicameral parliamentary system.
 The lower chamber, formally known as the Chamber of Representatives (Croatian: "Zastupnički dom") thus became the only parliamentary chamber and became known simply as the Croatian Parliament.
Oregon’s Territorial Legislature was a bicameral legislative body created by the United States Congress in 1848 as the legislative branch of the government of the Oregon Territory.
