paragraph_text: Early speculations about the nature of the chemical bond, from as early as the 12th century, supposed that certain types of chemical species were joined by a type of chemical affinity. In 1704, Sir Isaac Newton famously outlined his atomic bonding theory, in ``Query 31 ''of his Opticks, whereby atoms attach to each other by some`` force''. Specifically, after acknowledging the various popular theories in vogue at the time, of how atoms were reasoned to attach to each other, i.e. ``hooked atoms '',`` glued together by rest'', or ``stuck together by conspiring motions '', Newton states that he would rather infer from their cohesion, that`` particles attract one another by some force, which in immediate contact is exceedingly strong, at small distances performs the chemical operations, and reaches not far from the particles with any sensible effect.''

paragraph_text: Israel is widely believed to possess weapons of mass destruction, and to be one of four nuclear-armed countries not recognized as a Nuclear Weapons State by the Non-Proliferation Treaty (NPT). The US Congress Office of Technology Assessment has recorded Israel as a country generally reported as having undeclared chemical warfare capabilities, and an offensive biological warfare program. Officially, Israel neither confirms nor denies possessing nuclear weapons.

paragraph_text: For historical reasons, the line formally begins at Shiomibashi Station in Osaka and crosses the Nankai Main Line, the company's other main line, at Kishinosato-Tamade Station, though operationally it starts at Namba Station together with the Nankai Line, diverges at Kishinosato-Tamade Station and goes to Gokurakubashi Station, to connect to Koyasan through Nankai Cable Line.

paragraph_text: The main theme for Rick and Morty by Ryan Elder was originally used in a rejected Cartoon Network pilot Roiland made called ``Dog World '', which was referenced in the episode`` Lawnmower Dog''.

paragraph_text: In Peter Jackson's film trilogy (2001 -- 2003), Saruman is significantly more active in the first two films than in their equivalent books, and he appears in several scenes that are not depicted in Tolkien's work. In the films, Saruman is depicted presenting himself outright as a servant of Sauron. Smith and Matthews suggest that Saruman's role is built up as a substitute for Sauron -- the story's main antagonist -- who never appears directly in the book. Jackson confirms this view in the commentary to the DVD. They also suggest that having secured veteran British horror actor Christopher Lee to play Saruman, it made sense to make greater use of his star status. Despite this increased role in the first two films, the scenes involving Saruman that were shot for use in the third film, The Lord of the Rings: The Return of the King, were not used in the cinematic release, a decision which ``shocked ''Lee. Jackson reasoned that it would be anticlimactic to show Saruman's fate in the second movie (after the Battle of Helm's Deep) and too retrospective for it to be in the third one. The cut scenes end with Saruman falling to his death from the top of Orthanc after being stabbed by Wormtongue and include material from the chapter The Scouring of the Shire. They are included at the start of the Extended Edition DVD release of the film.

paragraph_text: In Miranda the court created safeguards against self-incriminating statements made after an arrest. The court held that "The prosecution may not use statements, whether exculpatory or inculpatory, stemming from questioning initiated by law enforcement officers after a person has been taken into custody or otherwise deprived of his freedom of action in any significant way, unless it demonstrates the use of procedural safeguards effective to secure the Fifth Amendment's privilege against self-incrimination"

paragraph_text: Poland's AA defences were no match for the German attack and the situation was similar in other European countries. Significant AA warfare started with the Battle of Britain in the summer of 1940. 3.7-inch HAA were to provide the backbone of the groundbased AA defences, although initially significant numbers of 3-inch 20-cwt were also used. The Army's Anti-aircraft command, which was under command of the Air Defence UK organisation, grew to 12 AA divisions in 3 AA corps. 40-mm Bofors entered service in increasing numbers. In addition the RAF regiment was formed in 1941 with responsibility for airfield air defence, eventually with Bofors 40mm as their main armament. Fixed AA defences, using HAA and LAA, were established by the Army in key overseas places, notably Malta, Suez Canal and Singapore.

paragraph_text: Vacuum is useful in a variety of processes and devices. Its first widespread use was in the incandescent light bulb to protect the filament from chemical degradation. The chemical inertness produced by a vacuum is also useful for electron beam welding, cold welding, vacuum packing and vacuum frying. Ultra-high vacuum is used in the study of atomically clean substrates, as only a very good vacuum preserves atomic-scale clean surfaces for a reasonably long time (on the order of minutes to days). High to ultra-high vacuum removes the obstruction of air, allowing particle beams to deposit or remove materials without contamination. This is the principle behind chemical vapor deposition, physical vapor deposition, and dry etching which are essential to the fabrication of semiconductors and optical coatings, and to surface science. The reduction of convection provides the thermal insulation of thermos bottles. Deep vacuum lowers the boiling point of liquids and promotes low temperature outgassing which is used in freeze drying, adhesive preparation, distillation, metallurgy, and process purging. The electrical properties of vacuum make electron microscopes and vacuum tubes possible, including cathode ray tubes. The elimination of air friction is useful for flywheel energy storage and ultracentrifuges.

paragraph_text: There are three main chemical pulping processes: the sulfite process dates back to the 1840s and it was the dominant method extent before the second world war. The kraft process, invented in the 1870s and first used in the 1890s, is now the most commonly practiced strategy, one of its advantages is the chemical reaction with lignin, that produces heat, which can be used to run a generator. Most pulping operations using the kraft process are net contributors to the electricity grid or use the electricity to run an adjacent paper mill. Another advantage is that this process recovers and reuses all inorganic chemical reagents. Soda pulping is another specialty process used to pulp straws, bagasse and hardwoods with high silicate content.

paragraph_text: On 7 August 1998, al-Qaeda struck the U.S. embassies in Kenya and Tanzania, killing 224 people, including 12 Americans. In retaliation, U.S. President Bill Clinton launched Operation Infinite Reach, a bombing campaign in Sudan and Afghanistan against targets the U.S. asserted were associated with WIFJAJC, although others have questioned whether a pharmaceutical plant in Sudan was used as a chemical warfare plant. The plant produced much of the region's antimalarial drugs and around 50% of Sudan's pharmaceutical needs. The strikes failed to kill any leaders of WIFJAJC or the Taliban.

paragraph_text: However, in 1883–84 Germany began to build a colonial empire in Africa and the South Pacific, before losing interest in imperialism. Historians have debated exactly why Germany made this sudden and short-lived move.[verification needed] Bismarck was aware that public opinion had started to demand colonies for reasons of German prestige. He was influenced by Hamburg merchants and traders, his neighbors at Friedrichsruh. The establishment of the German colonial empire proceeded smoothly, starting with German New Guinea in 1884.

paragraph_text: The Protocol for the Prohibition of the Use in War of Asphyxiating, Poisonous or other Gases, and of Bacteriological Methods of Warfare, usually called the Geneva Protocol, is a treaty prohibiting the use of chemical and biological weapons in international armed conflicts. It was signed at Geneva on 17 June 1925 and entered into force on 8 February 1928. It was registered in League of Nations Treaty Series on 7 September 1929. The Geneva Protocol is a protocol to the Convention for the Supervision of the International Trade in Arms and Ammunition and in Implements of War signed on the same date, and followed the Hague Conventions of 1899 and 1907.

paragraph_text: On November 12, the league announced the defending champion San Jose SaberCats would be ceasing operations due to "reasons unrelated to League operations". A statement from the league indicated that the AFL is working to secure new, long-term owners for the franchise. This leaves the AFL with eight teams for 2016.

paragraph_text: The Office 2003 XML Reference Schemas are included in the Microsoft Open Specification Promise, a legal statement concerning unrestricted use of Microsoft intellectual property.

paragraph_text: After the war he returned to academic life, as a chemistry professor at the University College of Wales, Aberystwyth, then in 1921 Principal of Manchester Municipal College of Technology. From 1938 to 1948 he was Vice-Chancellor of the University of Leeds. This included the Second World War, in which he also served in the Home Guard and for six months was in charge of the chemical warfare establishment at Porton Down.

paragraph_text: A rare - earth element (REE) or rare - earth metal (REM), as defined by IUPAC, is one of a set of seventeen chemical elements in the periodic table, specifically the fifteen lanthanides, as well as scandium and yttrium. Scandium and yttrium are considered rare - earth elements because they tend to occur in the same ore deposits as the lanthanides and exhibit similar chemical properties. For the same set of mineralogical, chemical, physical (especially electron shell configuration), and related reasons, a broader definition of rare earth elements including the actinides is encountered in some cases. Thorium is a significant component of monazite and other important rare earth minerals, and uranium and decay products are found in others. Both series of elements begin on the periodic table in group 3 under yttrium and scandium.

paragraph_text: To make pulp from wood, a chemical pulping process separates lignin from cellulose fibres. This is accomplished by dissolving lignin in a cooking liquor, so that it may be washed from the cellulose; this preserves the length of the cellulose fibres. Paper made from chemical pulps are also known as wood-free papers–not to be confused with tree-free paper; this is because they do not contain lignin, which deteriorates over time. The pulp can also be bleached to produce white paper, but this consumes 5% of the fibres; chemical pulping processes are not used to make paper made from cotton, which is already 90% cellulose.

paragraph_text: European Union – In a statement, the EU said "the evidence points towards yet another chemical attack by the regime" and "it is a matter of grave concern that chemical weapons continue to be used, especially on civilians. The European Union condemns in the strongest terms the use of chemical weapons and calls for an immediate response by the international community". It also called for the United Nations Security Council to identify the perpetrators and for Russia and Iran to influence Assad against launching such attacks. United Nations – On 10 April 2018, the United Nations Security Council failed to adopt three competing resolutions on an inquiry into the chemical attack, with Russia and the United States clashing over the issue and exchanging military threats.The World Health Organization released a statement, with a reference to outside medical sources, that 43 people died while suffering "symptoms consistent with exposure to highly toxic chemicals."

paragraph_text: Kerry said on September 9 in response to a reporter's question about whether Syrian President Bashar al-Assad could avert a military strike: "He could turn over every single bit of his chemical weapons to the international community in the next week. Turn it over, all of it, without delay, and allow a full and total accounting for that. But he isn't about to do it, and it can't be done, obviously." This unscripted remark initiated a process that would lead to Syria agreeing to relinquish and destroy its chemical weapons arsenal, as Russia treated Kerry's statement as a serious proposal. Russian Foreign Minister Sergey Lavrov said Russia would work "immediately" to convince Syria relinquish and destroy its large chemical weapons arsenal. Syria quickly welcomed this proposal and on September 14, the UN formally accepted Syria's application to join the convention banning chemical weapons, and separately, the U.S. and Russia agreed on a plan to eliminate Syria's chemical weapons by the middle of 2014. On September 28, the UN Security Council passed a resolution ordering the destruction of Syria's chemical weapons and condemning the August 21 Ghouta attack.

paragraph_text: On 1 November 1993, under the third Delors Commission, the Maastricht Treaty became effective, creating the European Union with its pillar system, including foreign and home affairs alongside the European Community. The 1994 European elections were held resulting in the Socialist group maintaining their position as the largest party in Parliament. The Council proposed Jacques Santer as Commission President but he was seen as a second choice candidate, undermining his position. Parliament narrowly approved Santer but his commission gained greater support, being approved by 416 votes to 103. Santer had to use his new powers under Maastricht to flex greater control over his choice of Commissioners. They took office on 23 January 1995.

Question: When did the union who made a statement about chemical warfare start and why?
Answer: 1 November 1993
