Question:  Catalytic reagents have been less successful , with most variations suffering from poor yield , poor enantioselectivity , or both . There are also issues with substrate scope , most having limitations with methylene transfer and aliphatic aldehydes . The trouble stems from the need for a nucleophilic sulfide that efficiently generates the ylide which can also act as a good leaving group to form the epoxide . Since the factors underlying these desiderata are at odds , tuning of the catalyst properties has proven difficult . Shown below are several of the most successful catalysts along with the yields and enantiomeric excess for their use in synthesis of ( E ) -stilbene oxide . Aggarwal has developed an alternative method employing the same sulfide as above and a novel alkylation involving a rhodium carbenoid formed in situ . The method too has limited substrate scope , failing for any electrophiles possessing basic substituents due to competitive consumption of the carbenoid . Treaty of Ciudad Juárez  The Treaty of Ciudad Juárez was a peace treaty signed between the then President of Mexico , Porfirio Díaz , and the revolutionary Francisco Madero on May 21 , 1911 . The treaty put an end to the fighting between forces supporting Madero and those of Díaz and thus concluded the initial phase of the Mexican Revolution . The treaty stipulated that Díaz , as well as his vice president Ramón Corral , were to step down by the end of May , and that he was to be replaced by Francisco León de la Barra as interim president and hold presidential elections . Those who had suffered losses due to the revolution would be the indemnified , and there would be a general amnesty . Díaz resigned on May 25 , and interim president Francisco León de la Barra was the new incumbent . Díaz and his family , his vice president Corral , plus José Yves Limantour and Rosendo Pineda left Mexico for exile . Significantly , the treaty did not mention or institute any social reforms that Madero had vaguely promised on previous occasions . It also left the Porfirian state essentially intact . Additionally , Madero supported the unpopular idea that all land disputes were to be settled through the courts , staffed by the old judges , a decision that led to outbreaks of sporadic violence , particularly in rural areas . On June 7 , 1911 , Madero entered Mexico City . In October 1911 he was elected president , under the banner of the Partido Constitucional Progresista , along with José María Pino Suárez , his new running mate as vice @-@ president . Madero pushed aside Francisco Vázquez Gómez , the vice presidential candidate for the Anti @-@ Reelectionist Party in 1910 , as being too moderate . fill in the blank  :  Catalytic reagents have been less successful , with most variations suffering from poor __________________ , poor enantioselectivity , or both .

Question:  The carving on the south wall to the east of the portico depicts Shiva and Parvati seated on their abode Mount Kailash . The four @-@ armed Shiva is seen with a crown and a disc behind it ( all damaged ) , the sacred thread across his chest , and a dressing gown covering up to the knee . Parvati , dressed in her finery with her hair falling to the front , looks away . Behind her at the right is a woman attendant holding the child , identified with her son Kartikeya , the war @-@ god . Many male and female attendants are seen behind the main figures . Shiva 's attendant , the skeleton @-@ like Bhringi , is seated at his feet . Other figures , not distinct , depict , among others , a royal @-@ looking tall person , ascetics , a fat figure , a dwarf , a bull ( the mount of Shiva ) , features of a Garuda , and two monkeys . The scenic beauty of the mountain is sculpted with the sky background amidst heavenly beings showering flowers on Shiva @-@ Parvati . This scene is interpreted as a gambling scene , where Parvati is angry as Shiva cheats in a game of dice . The carved panel facing this one is a two @-@ level depiction of Ravana lifting Kailash . The upper scene is Mount Kailash , where Shiva and Parvati are seated . The eight @-@ armed , three @-@ eyed Shiva wears headgear with a crescent and disc behind it . Most of his arms are broken , two of them resting on attendants ' heads . The Parvati figure , seated facing Shiva , remains only as a trunk . The panel is flanked by door keepers . Attendants of Shiva are also seen in the relief but mostly in a damaged state . Bhringi is seated near Shiva 's feet and to his left is the elephant @-@ headed son of Shiva , Ganesha . In this ensemble , the ten @-@ headed demon @-@ king Ravana is seen , with only one head left unscathed , and out of his twenty arms , only a few are discernible . Around Ravana are several demons . Numerous figures are seen above Shiva : the god Vishnu , riding his mount Garuda , to his left ; a skeleton @-@ figure ; and in a recess , Parvati 's mount , a tiger is depicted . A legend relates to both these panels . Once , Parvati was annoyed with Shiva . At this moment , Ravana , who was passing by Mount Kailash , found it as an obstruction to his movement . Upset , Ravana shook it vigorously and as a result , Parvati got scared and hugged Shiva . Enraged by Ravana 's arrogance , Shiva stamped down on Ravana , who sang praises of Shiva to free him of his misery and turned into an ardent devotee of Shiva . Another version states that Shiva was pleased with Ravana for restoring Parvati 's composure and blessed him . fill in the blank  :   The carving on the south wall to the east of the portico depicts Shiva and Parvati __________________ on their abode Mount Kailash .
