To avoid a false-positive result, the test will be done before any pelvic exam or transvaginal ultrasound. These tests can cause a release of fetal fibronectin and lead to a false-positive result. Intercourse and vaginal bleeding can affect the test results, too. If you experience vaginal bleeding or have had sex within the last 24 hours, the test probably won't be done.

Positive. A positive result means that fetal fibronectin is present in your cervical secretions. If you have a positive result between weeks 22 and 34, you're at increased risk of premature birth within seven days.

In a function that returns a scalar type, the expression's result will automatically be cast into the function's return type as described for assignments. But to return a composite (row) value, you must write an expression delivering exactly the requested column set. This may require use of explicit casting.

If you declared the function with output parameters, write just RETURN NEXT with no expression. On each execution, the current values of the output parameter variable(s) will be saved for eventual return as a row of the result. Note that you must declare the function as returning SETOF record when there are multiple output parameters, or SETOF sometype when there is just one output parameter of type sometype, in order to create a set-returning function with output parameters.

The current implementation of RETURN NEXT and RETURN QUERY stores the entire result set before returning from the function, as discussed above. That means that if a PL/pgSQL function produces a very large result set, performance might be poor: data will be written to disk to avoid memory exhaustion, but the function itself will not return until the entire result set has been generated. A future version of PL/pgSQL might allow users to define set-returning functions that do not have this limitation. Currently, the point at which data begins being written to disk is controlled by the work_mem configuration variable. Administrators who have sufficient memory to store larger result sets in memory should consider increasing this parameter.

The searched form of CASE provides conditional execution based on truth of Boolean expressions. Each WHEN clause's boolean-expression is evaluated in turn, until one is found that yields true. Then the corresponding statements are executed, and then control passes to the next statement after END CASE. (Subsequent WHEN expressions are not evaluated.) If no true result is found, the ELSE statements are executed; but if ELSE is not present, then a CASE_NOT_FOUND exception is raised.

The target is a record variable, row variable, or comma-separated list of scalar variables. The target is successively assigned each row resulting from the query and the loop body is executed for each row. Here is an example:

When control reaches the assignment to y, it will fail with a division_by_zero error. This will be caught by the EXCEPTION clause. The value returned in the RETURN statement will be the incremented value of x, but the effects of the UPDATE command will have been rolled back. The INSERT command preceding the block is not rolled back, however, so the end result is that the database contains Tom Jones not Joe Jones.

These chronicles do not mention Yue's masters teaching him martial arts style; just archery, spearplay and military tactics. However non-historical or scholarly sources state, in addition to those already mentioned, Zhou Tong taught Yue other skills such as hand-to-hand combat and horseback riding. Yet again, these do not mention any specific martial arts style. One legend says Zhou took young Yue to an unspecified place to meet a Buddhist hermit who taught him the Emei Dapeng qigong (峨嵋大鵬氣功) style. This is supposedly the source of his legendary strength and martial arts abilities.[12][16] According to thirteenth generation lineage Tai He ("Great Harmony") Wudangquan master Fan Keping (范克平), Zhou Tong was a master of various "hard qigong" exercises.[23][24]

The Biography of Yue Fei states that Yue left his ailing mother with his first wife while he went to fight the Jin armies. However she "left him (and his mother) and remarried".[6] He later took a second wife and even discussed "affairs" pertaining to his military career with her. He truly loved her, but his affection for her was second to his desire to rid China of the Jurchen invaders. Her faithfulness to him and his mother was strengthened by the fear that any infidelity or lacking in her care of Lady Yue would result in reprisal.[6]

According to legend, Yue combined his knowledge of internal martial arts and spearplay learned from Zhou Tong (in Shaolin) to create the linear fist attacks of Xingyi boxing.[12][61] One book claims he studied and synthesized Buddhism's Tendon Changing and Marrow Washing qigong systems to create Xingyi.[62] On the contrary, proponents of Wudangquan believe it is possible that Yue learned the style in the Wudang Mountains that border his home province of Henan. The reasons they cite for this conclusion are that he supposedly lived around the same time and place as Zhang Sanfeng, the founder of t'ai chi; Xingyi's five fist attacks, which are based on the Five Chinese Elements theory, are similar to tai-chi's "Yin-yang theory"; and both theories are Taoist-based and not Buddhist.[63] The book Henan Orthodox Xingyi Quan, written by Pei Xirong (裴锡荣) and Li Ying'ang (李英昂), states Xingyi master Dai Longbang

Several other martial arts have been attributed to Yue Fei, including Yuejiaquan (Yue Family Boxing), Fanziquan (Tumbling Boxing), and Chuōjiǎo quan (Feet-Poking Boxing), among others.[70][71][72] The "Fanzi Boxing Ballad" says: "Wumu has passed down the Fanziquan which has mystery in its straightforward movements." Wumu (武穆) was a posthumous name given to Yue after his death.[13] One Chuojiao legend states Zhou Tong learned the style from its creator, a wandering Taoist named Deng Liang (鄧良), and later passed it onto Yue Fei, who is considered to be the progenitor of the style.[70][73]

After the death of Sun Yat-sen in 1925 the mood was changing in the party toward the communists. In August the left-wing KMT leader Liao Zhongkai was assassinated and the right-wing leader Hu Hanmin, the suspected mastermind, was exiled to the Soviet Union, leaving the pro-communist Wang Jingwei in charge. Opposing communist encroachment, the right-wing Western Hills Group vowed to expel the communists from the KMT. The "Canton Coup" on 20 March 1926 saw Chiang solidify his control over the Nationalists and their army against Wang Jingwei, the party's left wing, its Communist allies, and its Soviet advisors.[114][115] By May, he had ended civilian control of the military[115] and begun his Northern Expedition against the warlords of the north. Its success led to the split of the KMT between Wuhan and Nanking and the purge of the communists in the April 12 Incident. Immediately afterwards Canton joined the purge under the auspice of Li Jishen, resulting in the arrest of communists and the suspension of left wing KMT apparatuses and labor groups. Later in 1927 when Zhang Fakui, a general supportive of the Wuhan faction seized Canton and installed Wang Jingwei's faction in the city, the communists saw an opening and launched the Guangzhou Uprising. Prominent communist military leaders Ye Ting and Ye Jianying led the failed defense of the city. Soon, control of the city reverted to Li Jishen.

In the late 19th century, China adopted the Western model of nation-state diplomacy. As the government of Tibet, China concluded several treaties (1876, 1886, 1890, 1893) with the British Indian government touching on the status, boundaries and access to Tibet.[29] Chinese government sources consider this a sign of sovereignty rather than suzerainty. However, by the 20th century British India found the treaties to be ineffective due to China's weakened control over the Tibetan local government. A British expeditionary force invaded Tibet in 1904 and mandated the signing of a separate treaty directly with the Tibetan government in Lhasa. In 1906, an Anglo-Chinese Convention was signed at Peking between Great Britain and China. It incorporated the 1904 Lhasa Convention (with modification), which was attached as Annex.[29][30] A treaty between Britain and Russia followed in 1907.[31] Article II of this treaty stated that "In conformity with the admitted principle of the suzerainty of China over Tibet, Great Britain and Russia engage not to enter into negotiations with Tibet except through the intermediary of the Chinese Government." China sent troops into Tibet in 1908. The result of the policy of both Great Britain and Russia has been the virtual annexation of Tibet by China.[29] China controlled Tibet up to 1912. Thereafter, Tibet entered the period described commonly as de facto independence, though it was recognized only by independent Mongolia as enjoying de jure independence.[32]

Groups such as the Madrid-based Committee to Support Tibet claim the death toll in Tibet since the 1950 People's Liberation Army invasion of Tibet to be 1,200,000 and have filed official charges of genocide against prominent Chinese leaders and officials.[129] This figure has been disputed by Patrick French, a supporter of the Tibetan cause who was able to view the data and calculations,[130][131] but rather, concludes a no less devastating death toll of half a million people as a direct result of Chinese policies.[132]

The most vocal supporters of the agreement came from the monastic community...As a result many Tibetans were willing to accept the agreement....Finally there were strong factions in Tibet who felt that the agreement was acceptable...this section was led by the religious community...In the Tibetans' view their independence was not a question of international legal status, but as Dawa Norbu writes, "Our sense of independence was based on the independence of our way of life and culture, which was more real to the unlettered masses than law or history, canons by which the non-Tibetans decide the fate of Tibet...This was the first formal agreement between Tibet and Communist China and it established the legal basis for Chinese rule in Tibet."[159] 2ff7e9595c
