PROBLEM: Cullen made his NHL debut in 1988 89 , appearing in 79 games with the Penguins and scoring 49 points . He was given a greater role with the Penguins the following year after Mario Lemieux missed 21 games due to a back injury and responded by scoring 32 goals and 92 points to finish third in team scoring . Additionally , he played for Team Canada at the 1990 World Championship , scoring four points in ten games . Cullen had his best season in 1990 91 . As one of the team 's top offensive centres , he scored 94 points in the Penguins ' first 65 games and played in his first NHL All @-@ Star Game . However , when Lemieux returned after missing an additional 50 @-@ games due to injury , Cullen 's playing time and production declined . The Penguins ' needs led them to complete a blockbuster trade on March 1 , 1991 . Cullen was sent to the Hartford Whalers , along with Zarley Zalapski and Jeff Parker in exchange for Hartford 's all @-@ time leading scorer , Ron Francis , along with Ulf Samuelsson and Grant Jennings . The Penguins almost turned down the deal as they were concerned about giving up Cullen 's playmaking and leadership abilities , while his former teammates credited Cullen as being the primary reason they were in a playoff position at the time the trade happened . After the Penguins won their first Stanley Cup that season , Phil Bourque later said it broke his heart that Cullen was not able to share in that championship . In Hartford , Cullen worked to overcome the team 's fans ' disappointment at losing Francis . The Hartford fans initially booed him to show their dissatisfaction with the trade . He scored 16 points in 13 regular season games to finish the season with 110 points combined between the Penguins and Whalers , and was the team 's best player in their first round loss to the Boston Bruins in the 1991 Stanley Cup Playoffs . He initially accepted an invitation to join the Canadian team at the 1991 Canada Cup , but subsequently chose not to participate as his contract had expired , leading to greater insurance concerns . Still without a contract when the 1991 92 season began , Cullen missed the first four games before signing a four @-@ year deal with Hartford worth a total of $ 4 million . He returned to score 77 points in 77 games in his first full season with the Whalers and represented the team at the 1992 All @-@ Star Game . Midway through the 1992 93 NHL season , the Whalers sent Cullen to the Toronto Maple Leafs for Toronto 's second round selection at the 1993 NHL Entry Draft . Cullen was excited to play for his father 's old team , but injuries reduced his ability to perform . His most significant injury was a herniated disc in his neck that doctors initially feared would end his career . A bulky neck brace allowed Cullen to return and play out his contract in Toronto . When the Leafs chose not to re @-@ sign him following the 1993 94 season , he returned to the Penguins for one season before Tony Esposito convinced him to sign with the Tampa Bay Lightning in 1995 . Cullen enjoyed immediate success with linemates Shawn Burr and Alexander Selivanov as the trio combined to score 130 points and helped lead the Lightning to the first playoff appearance in franchise history . They were eliminated by the Philadelphia Flyers in five games while Cullen led the team in playoff scoring with three goals and three assists . The Lightning looked to improve in 1996 97 ; Cullen was leading the team in scoring , but was suffering flu @-@ like symptoms that he could not shake . As Tampa was fighting for a playoff spot , he played through his condition for weeks . fill in the blank : Cullen made his NHL debut in 1988 89 , appearing in __________________ games with the Penguins and scoring 49 points .

SOLUTION: 79

PROBLEM: 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 Juarez The Treaty of Ciudad Juarez was a peace treaty signed between the then President of Mexico , Porfirio Diaz , and the revolutionary Francisco Madero on May 21 , 1911 . The treaty put an end to the fighting between forces supporting Madero and those of Diaz and thus concluded the initial phase of the Mexican Revolution . The treaty stipulated that Diaz , as well as his vice president Ramon Corral , were to step down by the end of May , and that he was to be replaced by Francisco Leon 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 . Diaz resigned on May 25 , and interim president Francisco Leon de la Barra was the new incumbent . Diaz and his family , his vice president Corral , plus Jose 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 Jose Maria Pino Suarez , his new running mate as vice @-@ president . Madero pushed aside Francisco Vazquez Gomez , 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 .

PROBLEM: The planning system is critical to the viability and operation of GA aerodromes . With many cities lacking scheduled air transport services between them , and with GA access to commercial airports becoming increasingly difficult and expensive , a viable network of aerodromes supporting GA air transport operations is regarded as an important national issue . However , there is no unified national planning policy specific to GA aerodromes , and planning decisions relating to these are based on local issues that are not required to consider the national impact . Because aircraft are excluded from noise control legislation , the only recourse for people affected by aircraft noise is through the planning process , and this issue is the principal factor on which the majority of planning decisions relating to GA land use are made . GA is a specialist subject often unfamiliar to Local Planning Authorities , and most planning decisions relating to GA either refuse permission , or grant it with restrictive conditions . Little Gransden is just one example of a GA airfield required to comply with planning restrictions on the number of movements permitted , thereby inhibiting further development . Such restrictions , if poorly conceived , can make GA operations unviable or even unsafe . fill in the blank : The planning system is __________________ to the viability and operation of GA aerodromes .
