Traditionally the feast also applied to sexual desires, which were supposed to be suppressed during the following fasting. Before Lent began, all rich food and drink were consumed in what became a giant celebration that involved the whole community, and is thought to be the origin of Carnival. The Lenten period of the Liturgical calendar, the six weeks directly before Easter, was originally marked by fasting and other pious or penitential practices. During Lent, no parties or celebrations were held, and people refrained from eating rich foods, such as meat, dairy, fat and sugar.
The giant celebration that involved the whole community is thought to be the origin of what festivity?
Carnival

The '98 season would begin on a somber note with the death of legendary broadcaster Harry Caray. After the retirement of Sandberg and the trade of Dunston, the Cubs had holes to fill and the signing of Henry Rodríguez, known affectionately as "H-Rod" to bat cleanup provided protection for Sammy Sosa in the lineup, as Rodriguez slugged 31 round-trippers in his first season in Chicago. Kevin Tapani led the club with a career high 19 wins, Rod Beck anchored a strong bullpen and Mark Grace turned in one of his best seasons. The Cubs were swamped by media attention in 1998, and the team's two biggest headliners were Sosa and rookie flamethrower Kerry Wood. Wood's signature performance was one-hitting the Houston Astros, a game in which he tied the major league record of 20 strikeouts in nine innings. His torrid strikeout numbers earned Wood the nickname "Kid K," and ultimately earned him the 1998 NL Rookie of the Year award. Sosa caught fire in June, hitting a major league record 20 home runs in the month, and his home run race with Cardinals slugger Mark McGwire transformed the pair into international superstars in a matter of weeks. McGwire finished the season with a new major league record of 70 home runs, but Sosa's .308 average and 66 homers earned him the National League MVP Award. After a down-to-the-wire Wild Card chase with the San Francisco Giants, Chicago and San Francisco ended the regular season tied, and thus squared off in a one-game playoff at Wrigley Field in which third baseman Gary Gaetti hit the eventual game winning homer. The win propelled the Cubs into the postseason once again with a 90–73 regular season tally. Unfortunately, the bats went cold in October, as manager Jim Riggleman's club batted .183 and scored only four runs en route to being swept by Atlanta. On a positive note, the home run chase between Sosa, McGwire and Ken Griffey, Jr. helped professional baseball to bring in a new crop of fans as well as bringing back some fans who had been disillusioned by the 1994 strike. The Cubs retained many players who experienced career years in '98, and after a fast start in 1999, they collapsed again (starting with being swept at the hands of the cross-town White Sox in mid-June) and finished in the bottom of the division for the next two seasons.
How many round-trippers did Rodriguez slug in his first season in Chicago?
31

Electrochemical migration (ECM) is the growth of conductive metal filaments on or in a printed circuit board (PCB) under the influence of a DC voltage bias. Silver, zinc, and aluminum are known to grow whiskers under the influence of an electric field. Silver also grows conducting surface paths in the presence of halide and other ions, making it a poor choice for electronics use. Tin will grow "whiskers" due to tension in the plated surface. Tin-Lead or solder plating also grows whiskers, only reduced by the percentage Tin replaced. Reflow to melt solder or tin plate to relieve surface stress lowers whisker incidence. Another coating issue is tin pest, the transformation of tin to a powdery allotrope at low temperature.
Along with silver and aluminum, what metal grows metal filaments when exposed to an electric field?
zinc
