Bobs Burgers The Movie everything we know about the Belchers film

Posted On Sep 10 2019 by

first_img Share your voice As you’d expect from a show where Tina has devoted herself to, uh, “erotic friend fiction,” Bob’s Burgers believes in fan service.”We’re thrilled to be invited to bring Bob’s Burgers to the big screen,” show creator Loren Bouchard said when the movie was announced. “We know the movie has to scratch every itch the fans of the show have ever had, but it also has to work for all the good people who’ve never seen the show. We also know it has to fill every inch of the screen with the colors and the sounds and the ever so slightly greasy texture of the world of Bob’s — but most of all it has to take our characters on an epic adventure. In other words, it has to be the best movie ever made. But no pressure, right?!” Release date, production infoGood burgers take time to cook. Look for the Bob’s Burgers movie to come to theaters in 2020. July 17 was the original date given, but voice actor John Roberts, who voices Linda, told Aesthetic Magazine he thinks it’ll be “a little later than they announced.”Cast: Who’s who?There’s no way this film can be made without the familiar voices behind the Belchers and their friends, so we’re going to assume the voice cast is the same as the show. (We’re rooting for non-Belchers, like Marshmallow and Gene’s friend Alex to be part of the movie too.) If we hear of special guest stars or confirmed minor characters who’ll make an appearance, we’ll note that here.  Belcher familyH.

But here’s what we know anyway. Kuchi Kopi gets litAccording to Entertainment Weekly, in 2018 Bouchard said the “movie will reunite Louise with her beloved nightlight Kuchi Kopi in her dreams for another trippy adventure.”Now ear this, LouiseWhy does Louise, the youngest Belcher, always wear pink bunny ears? Bouchard says the movie will explain it. The Belchers are coming to a theater near you. Fox Animation Studios/Walt Disney Studios Say it in Linda’s voice: All right! The Belcher family, of Bob’s Burgers fame, is heading to the big screen.Bob and Linda Belcher run Bob’s Burgers restaurant in an unnamed seaside town and live above their restaurant with their three quirky kids, Tina, Gene and Louise. The critically acclaimed animated TV show has been renewed for a 10th season on Fox. The show is known for its sassy humor, family love and musical numbers.Now, there’s going to be a movie. It won’t hit theaters until 2020, but devoted fans can’t wait. Here’s what we know so far. We’ll add to this post as new information is revealed.The basicsWhat’s it called?

first_img.Facebook remains the most popular social networking site among Bangladeshi youth by a fairly wide margin.The other popular social networks are imo, Youtube, WhatsApp, and Viber, says a survey conducted by Org-Quest Research Ltd and initiated by Prothom Alo.The survey was conducted on 1,200 youths, who are15 to 30 years old. Of them, 494 use social networks regularly.When asked about their favourite social network, 95 per cent youths said their first preference is Facebook.Among the 494, a total of 468 youths have only one social networking site account, Facebook, indicating 94 per cent youths consider Facebook their social network.The 494 survey participants spend 52 minutes on average on Facebook every day.Of them, 80 per cent give 30 minutes to 1 hour daily and the rest spend more than 1 hour on Facebook.The second choice of the youths is imo as 57 per cent of them use the app based site regularly.Youtube stays in the third position among Bangladeshi youths. Among the survey participants, 33 per cent youths regularly use Youtube. The video-sharing site is more popular among boys than girls.WhatsApp is in the fourth and Viber in the fifth position among youths’ choice list of social networks.Social network expert Fahim Masroor told Prothom Alo, young people are losing their depth of thought because of this Facebook addiction.This addiction is triggering off social unrest, intolerance and militancy, he said.Fahim Masroor thinks the authorities should give the youth reading rooms, sports facilities, and other recreational activities so that technology cannot control them. *The article originally published in Prothom Alo print edition has been rewritten in English by Imam Hossain.last_img read more

Sri Lanka beefs up tourist hotspot security after violence

Posted On Sep 3 2019 by

first_imgAn elephant plays basketball during a show at the national zoological gardens in Colombo, Sri Lanka March 21,2018. File photo : ReutersSri Lanka announced Friday it would establish new police posts and step up patrols at popular resorts after a spate of sexual attacks and violence targeting foreign tourists.Police chief Pujith Jayasundara said 20 new stations would be established at holiday hotspots to protect visitors from touts and criminals, despite concerns his force was already overstretched.”I wish we had more men and resources for this job, but we are making adjustments to our deployments to ensure better productivity,” Jayasundara said.He added the measures were decided after a Dutch tourist was sexually harassed and several other tourists were assaulted by a gang at a hotel in the southern resort town of Mirissa last week.Five Israeli tourists were beaten up in the same area this week and 14 men have been arrested over the two incidents, police said. Local media reports have catalogued several sexual harassment complaints by foreign tourists, with many reluctant to make official complaints for fear of drawn-out court proceedings.Tourism Minister John Amaratunga appealed to victims to come forward and promised to cover the expenses of those who return to the island to help identify perpetrators.The US State Department warned last year that sexual crimes against women were on the rise in Sri Lanka.While most reported incidents involved non-physical acts such as cat calls and verbal harassment, there were several serious incidents of sexual threats, groping and rape.”Incidents have also occurred at tourist beaches and smaller hotels in the Southern province,” the travel advisory noted.In 2014, a Sri Lankan court sentenced a local politician and three of his supporters to 20 years in jail for the 2011 murder of British tourist Khuram Shaikh on Christmas Eve and gang rape of his Russian partner.Shaikh, a 32-year-old Red Cross worker, had tried to stop a brawl at a southern beach resort when a gang attacked and killed him.His girlfriend, who was knocked unconscious in the brutal assault, returned to Sri Lanka in 2014 to give evidence and identified one of her attackers in court.last_img read more


Kim Moon on the verge of new era

Posted On Sep 3 2019 by

first_imgSouth Korean President Moon Jae-in and North Korean leader Kim Jong Un meet in the truce village of Panmunjom. ReutersSmiling and holding hands, North Korean leader Kim Jong Un and South Korean President Moon Jae-in met at the heavily fortified demilitarised zone between the countries on Friday in the first summit for the two Koreas in over a decade.Scenes of Moon and Kim joking and walking together marked a striking contrast to last year’s barrage of North Korean missile tests and its largest ever nuclear test that led to sweeping international sanctions and fears of a fresh conflict on the Korean peninsula.The dramatic meeting, aimed at ending their decades-long conflict, comes weeks before Kim is due to meet US president Donald Trump.“We are at a starting line today, where a new history of peace, prosperity and inter-Korean relations is being written,” Kim said before the two Korean leaders and their top aides began talks.Moon and Kim are expected to discuss denuclearisation and exchanges between the Koreas and also will plant a memorial tree at the border truce village of Panmunjom. Just days before the summit, Kim said North Korea would suspend nuclear and long-range missile tests and dismantle its only known nuclear test site.But there is widespread scepticism about whether Kim is ready to abandon the hard-earned nuclear arsenal his country has defended and developed for decades as what it says is a necessary deterrent against U.S. invasion.Two earlier summits between the leaders of North and South Korea, in Pyongyang in 2000 and 2007, failed to halt the North’s weapons programmes or improve relations in a lasting way.“Today, rather than create results we won’t be able to carry out like in the past, we should make good results by talking frankly about current issues, issues of interest,” Kim said.First Across The LineMoon greeted Kim at the military demarcation line, making Kim the first North Korean leader to set foot in the South since the 1950-53 Korean War.In an unplanned move, Kim invited Moon to step briefly across into North Korea, before the two leaders crossed back into South Korea holding hands.The two were handed flowers by a South Korean children, residents of a village situated in the demilitarised zone.The pair were met on a red carpet by a South Korean honour guard in historical costumes and playing traditional music.Kim wore glasses and his trademark black Mao suit, while the rest of the North Korean delegation appeared in military uniforms or Western attire.“A new history starts now. An age of peace, from the starting point of history,” Kim wrote in Korean in a guest book in the South’s Peace House before talks began.“I hope we will be able to talk frankly and come to an agreement to give a big present for the Koreans and the people around the world who wish for peace,” Moon said as the two began their official talks.Minutes before Kim entered Peace House, a North Korean security team conducted a sweep for explosives and listening devices, and sprayed apparent disinfectant in the air, on the chairs, and on the guest book.The United States is hopeful talks between Kim and Moon will make progress on achieving peace and prosperity, the White House said in a statement as the two men began their summit.The White House also said it looks forward to continuing discussions with South Korea in preparation for the planned meeting of Trump and Kim in the coming weeks.Just months ago, Trump and Kim were trading threats and insults as the North made rapid advances in pursuit of nuclear-armed missiles capable of hitting the United States.Earlier Friday, North Korea’s official KCNA news agency said Kim would “open-heartedly discuss with Moon Jae-in all the issues arising in improving inter-Korean relations and achieving peace, prosperity and reunification of the Korean peninsula.”Moon travelled to the meeting in a large motorcade, stopping briefly to greet dozens of summit supporters waving South Korean flags near the presidential Blue House in Seoul.Hundreds of demonstrators were seen gathering in downtown Seoul from early morning to protest or support the summit.Unending HostilitiesThe two countries expect to release a joint statement late on Friday – possibly called the Panmunjom Declaration – that could address denuclearisation and peace, and an improvement in relations, South Korean officials said.Impoverished North Korea and the rich, democratic South are technically still at war because the Korean War ended in a truce, not a peace treaty.The United States stations 28,500 troops in South Korea as a legacy of the Cold War conflict, which pitted the South, the United States and United Nations forces against the communist North, backed by China and Russia.Kim and Trump are expected to meet in late May or June, with Trump saying on Thursday he was considering several possible dates and venues.The White House released two photographs of then Secretary of State-designate and CIA chief Mike Pompeo’s meeting with Kim in North Korea over the Easter weekend to discuss the planned summit. It was Kim’s first known meeting with a US official.The latest Korean summit has particular significance not least because of its venue: the Demilitarised Zone, a 160-mile (260-km) long, 2.5-mile (4-km) wide strip of land created in the 1953 armistice to serve as a buffer between the South and North.last_img read more


Jones Plans To Run In Hopes of Rebuilding Morgan Football

Posted On Sep 1 2019 by

first_imgBY MARK F. GRAY, Special to the AFROMorgan State’s interim head coach Ernest Jones plans to run into the challenge of rebuilding the football program.  In an era of run pass option (RPO) offense Jones prefers limiting the pass, focusing on the rush, and hard nose defense as they look to restore credibility to the program which is three years removed from sharing a Mid-Eastern Athletic Conference championship.“This is a new day and are creating a new identity on offense,” Jones said to the AFRO.  “We don’t care who knows it. We are going to line up and give the ball to our bruising, physical running backs. You may know what’s coming but it will be hard to stop”.Morgan State University Interim Coach Ernest Jones (Courtesy Photo/Twitter.com @MorganStBears)Jones faces an uphill battle as he tries to re-energize their students, fan base, and keep the team motivated. The Bears are ineligible for postseason this year as the program failed to meet the NCAA’s Academic Progress Rate (APR) score of 930 for the second time in three years. The APR monitors eligibility and student-athletes’ progress toward graduation. Despite the improvement from 893 to 920 Morgan State can only be a spoiler to teams who are contending for the MEAC title and berth in the Celebration Bowl.The NCAA sanctions also limit the Bears to two less hours of team activities per week during the season and four fewer hours per week in the offseason. Morgan State also will not be allowed to have spring practice next year. That figures to complicate the rebuilding process that was stunted by the hasty departure of Lee Hull in 2015 who left to become receiver’s coach with the Indianapolis Colts.Morgan State has lost their stability on the sideline that marked Donald Hill-Eley’s 12-year tenure which ended in 2013. Since then Morgan’s program has returned to the days of the revolving door of head coaching that plagued them after the glory days of Hall of Fame coach Earl Banks era until Hill-Eley’s run. Jones is the Bears third head coach in four years and is ready to put his stamp on the team.He has been open about how the APR dilemma could work to their advantage by forcing players to compete in the classroom with the same voracity they bring to the stadium on gameday.  However, the culture he is trying to create is old school “three yards and a cloud of dust” offensively while playing physical defense in hopes of shrinking the opposition’s time of possession while controlling the ball on the ground.Morgan St. will feature a trio of backs who are physical and versatile but the constant for all the skill position players is blocking this year. Josh Chase, Jordan Riggins, and Jalen Jackson fit that mold. This backfield by committee personifies what Jones is looking for from his running back who average 200 pounds and figure to do most of their work between the tackles grounding out tough yards.Meanwhile, quarterback DeAndre Harris, a converted basketball player, figures to start the season opener vs. Towson after completing almost 60 percent of his passes last year for 781 yards with 10 TD and eight interceptions. He is being challenged by redshirt freshman D.J. Golatt. Josh Chase and Jordan Riggins give Morgan over 400 pounds at tailback which could wear down defenses. They also feature eight receivers including Notre Dame transfer Corey Holmes.We’re not going to be a trick team; we’re not going to try and beat you with a snap count. If you’re looking for 30 or 40 passes and 60 or 70 points, that probably won’t happen unless we can get it by running the football.”last_img read more


Converting waste heat into electricity works better in two dimensions

Improved thermoelectric materials with atomic layer deposition Citation: Converting waste heat into electricity works better in two dimensions (2016, June 8) retrieved 18 August 2019 from https://phys.org/news/2016-06-electricity-dimensions.htmlcenter_img (Phys.org)—The large amount of waste heat produced by power plants and automobile engines can be converted into electricity due to the thermoelectric effect, a physics effect that converts temperature differences into electrical energy. Now in a new study, researchers have confirmed theoretical predictions that two-dimensional (2D) materials—those that are as thin as a single nanometer—exhibit a significantly higher thermoelectric effect than three-dimensional (3D) materials, which are typically used for these applications. © 2016 Phys.org Journal information: Proceedings of the National Academy of Sciences The study, which is published in a recent issue of the Proceedings of the National Academy of Sciences by Sunao Shimizu et al., could provide a way to improve the recycling of waste heat into useful energy.Previous research has predicted that 2D materials should have better thermoelectric properties than 3D materials because the electrons in 2D materials are more tightly confined in a much smaller space. This confinement effect changes the way that the electrons can arrange themselves. In 3D materials, this arrangement (called the density of states distribution) is continuous, but in 2D materials, this distribution becomes quantized—only certain values are allowed. At certain densities, the quantization means that less energy is required to move electrons around, which in turn increases the efficiency with which the material can convert heat into electrical energy.Experimentally demonstrating this thermoelectric enhancement in 2D materials has been challenging because of the difficulty in fabricating 2D materials with the appropriate electron arrangement. Although previous experiments have demonstrated this enhancement in certain materials, it has been unclear whether the mechanism of enhancement agrees with predictions.In the new study, the researchers fabricated a 2D electron gas on the surface of a zinc oxide semiconductor, and showed that this material’s thermoelectric properties can be directly compared to those of bulk zinc oxide because both 2D and 3D versions have a single electron band. “In order to discuss the thermoelectric effect unique to 2D materials, it is very important to control the carrier density in the 2D layers,” Shimizu, a researcher at the RIKEN Center for Emergent Matter Science in Saitama, Japan, told Phys.org. “Our approach, the electric field effect with ionic gating, enabled us to produce an ideal 2D layer and to control the carrier number.”Using their new approach, the researchers found that the 2D electron gas exhibits a thermoelectric effect that is approximately three times larger than that of the 3D semiconductor.This enhancement ratio is about twice as large as predicted by a simple simulation, which the researchers suspect could be due to inaccuracies in estimating the thickness of the 2D layer, where even a few nanometers can make a big difference. They hope that future research will lead to more accurate approaches of estimating the thickness, providing a better measure of the thermoelectric effect enhancement. “The results of this study clearly remind us of the importance of low-dimensional materials and devices for realizing high-performance thermoelectric conversion,” Shimizu said. “In the future, I would like to investigate other low-dimensional materials, including nanotubes and quantum dots.”last_img read more


Former FARC Leaders Announce New Stage O

Posted On Aug 31 2019 by

first_img Jacobo Alape via YouTube by NPR News Sasha Ingber 8.29.19 4:45pm Top rebels from the Revolutionary Armed Forces of Colombia have announced a “new stage of fighting,” despite a peace accord that the leftist guerrilla group signed with the national government almost three years ago.In a 32-minute YouTube video posted Thursday, more than 20 armed fighters stood in green fatigues and in front of a sign that read, “As long as there is a will to fight there will be hope for victory.”A guerrilla leader involved in the peace negotiations accused the government of betraying key components of the deal. “The state has not fulfilled its most important obligation, which is to guarantee the life of its citizens and especially avoid assassinations for political reasons,” said Luciano Marin, known widely by his nom de guerre, Iván Márquez.Under the peace treaty, thousands of Marxist- and Leninist-inspired guerrillas gave up their arms in exchange for the Colombian government’s commitment to protecting them and to building infrastructure in poor, isolated communities in the countryside. In May, Marin said that it was a mistake for FARC fighters to surrender their weapons without first getting guarantees.In the video, which appeared to be filmed in the jungle, Marin said the group planned to work with the National Liberation Army (ELN), another leftist guerrilla army which has resorted to kidnapping, extortion and violence.Hours later, an ELN leader embraced the announcement. “Better late than never,” Omar Gómez, known as Uriel, said through a face mask after giving a thumbs up and a clenched fist.Former FARC commander Rodrigo Londoño, now the president of Colombia’s Revolutionary Alternative Common Force political party, reiterated his commitment to the peace accord. He said on Thursday that the majority support working toward peace. “Now more than ever, our commitment as a majority, as a party, as a country, is to peace, defending and complying with the agreement,” he said. “Anyone who strays away from peace is mistaken, as those who have always attacked it.”Negotiations to end Colombia’s longest war, tracing back to the 1960s, started in 2012. Former President Juan Manuel Santos and Londoño signed a peace agreement in 2016. The move triggered a new wave of violence from armed groups that fought to take control of the FARC’s territory, displacing thousands in rural communities. Colombians, in a narrow margin, had previously voted to reject a peace deal.Last year, Colombians elected President Iván Duque, who campaigned on a promise to revise the controversial peace deal. A conservative populist, he said the agreement was too lenient for rebels who had kidnapped Colombian citizens and committed other atrocities.
