Guessing game: Cavs enter NBA draft unsure of LeBron’s plans

first_imgJiro Manio arrested for stabbing man in Marikina Volcano watch: Island fissures steaming, lake water receding By that time, the Cavs, still stinging from a Finals sweep at the hands of the Golden State Warriors, hope to have chosen a player that makes them more appealing to the three-time champion, who is mulling whether to leave them — and his Northeast Ohio home — for the second time in his career.Anything seems possible at this point. James and his representatives have kept an air-tight lid on their plans.The Cavs, too, have been secretive while general manager Koby Altman prepares for his first draft by consulting with his staff on what to do with the No. 8 overall pick, the one they received last summer in the seismic trade that sent All-Star point guard Kyrie Irving to the Boston Celtics.It’s quite a quandary for Cleveland, and James isn’t helping the Cavs by keeping them in suspense.It’s also possible that James hasn’t made up his mind.ADVERTISEMENT MOST READ Walker might not be enough to keep James here, but he would give the Cavs a new star to build around.James has remained off social media since the playoffs began in April, and his self-imposed blackout has continued since the Finals ended.He’s been quiet, but there’s no doubt he’s watching.Every move.Sports Related Videospowered by AdSparcRead Next Don’t miss out on the latest news and information.

Federer stretches winning streak on grass to 17 in Halle Christopher Tolkien, son of Lord of the Rings author, dies aged 95 Following Game 4 in the Finals, James said he’ll factor in his family’s well-being along with his thirst to win more titles into a decision that once again has Cleveland edgy.“I still want to be in championship mode,” he said. “I think I’ve shown this year why I will still continue to be in championship mode.”And while there are numerous unknowns, there is one indisputable fact: the Cavs must upgrade their roster to have any chance of keeping James and continuing a relationship that was resurrected in 2014.After yielding to Irving’s request and trading him, the Cavs spent all last season trying to replace him. They never came close, and without a dependable second scoring option or a guard, James was forced to shoulder a heavier load than ever. He succeeded in getting to his eighth straight Finals, but was then overmatched by the deeper Warriors.To remain viable contenders and keep James happy and healthy, the Cavs must address their backcourt issue this summer, either in the draft, through free agency or a trade.With this year’s draft top loaded with quality big men, there’s a strong possibility the Cavs will have their pick of one of the elite guards, perhaps Oklahoma’s Trae Young or Alabama’s Collin Sexton — two players James has praised in the past.Young was college basketball’s most electrifying player last season, averaging 27.4 points and 8.7 assists even while teams designed defenses specifically to stop him. James kept an eye on the 6-foot-2 scoring phenom from afar and is intrigued by not only his ability to break down teams but his unselfishness.Young could be gone by the time the Cavs are on the clock, but Sexton would be a nice backup plan. The 6-foot-3 guard averaged 19.2 points and 3.6 assists as a freshman and showed he’s got a big-game gene, carrying the Crimson Tide on a run in the SEC tournament that secured the school’s first NCAA berth since 2012.Sexton worked out for the Cavs at their training facility and owner Dan Gilbert referred to the 19-year-old as “a very interesting draft prospect” on Twitter.There’s also a chance that Cleveland could select a guard to use to entice a major trade. The Cavs have long been interested in Charlotte’s Kemba Walker, who will be a free agent after next season, and landing a player of that caliber would send a resounding message to James that they intend to keep chasing championships.

Mazda’s new hybrid emits H2O

first_imgBy Yuri Kageyama THE ASSOCIATED PRESS YOKOHAMA, Japan – Mazda unveiled a new hybrid vehicle on Tuesday that uses hydrogen fuel to power an electric motor. The Japanese automaker said it will be available for leasing in Japan next year. The Mazda Premacy Hydrogen RE Hybrid, shown to reporters ahead of its debut at the Tokyo Motor Show later this month, operates on a rotary engine, which runs almost silently because it doesn’t have pistons like standard engines. Hydrogen is combined with oxygen from the air to power the vehicle. It emits only water, rather than pollutants that have been linked to global warming. The new hybrid runs on hydrogen stored in a tank, but it can switch to gas when hydrogen runs out. Like other global automakers, Mazda, an affiliate of Ford Motor Co., has been working on hydrogen vehicles as consumers grow more interested in automobiles that don’t rely on fossil fuels. Ford’s 12-passenger shuttle bus powered by a 6.8-liter internal combustion hydrogen engine is operating at Orlando International Airport in Florida. Ford says its hydrogen technology is closest to mass production. The Michigan automaker said it could bring internal combustion hydrogen technology to market within five years but is dealing with fuel storage limits, public fear of hydrogen and availability at filling stations. Mazda officials said the latest hydrogen hybrid is an improvement over its previous hydrogen vehicle, leased since 2006, extending its run on a full tank of hydrogen from 62 miles to 124 miles. The new car also has a lithium-ion battery that drives the motor and recharges itself using energy from braking, further conserving on electricity. Mazda refused to say what supplier was providing the battery. Mazda Motor Corp. said it has no plans to lease the car outside Japan. The leasing fee will resemble the predecessor at about $3,500 a month, according to Mazda, so it’s aimed at government and ecological organizations. At its research facility in Yokohama, Mazda also showed a “concept car,” or show model, called Taiki, that it said was inspired by flowing wind. Its curvaceous surface creased with swooping lines, the slinky car looked like a metal stingray. Laurens van den Acker, general manager of design, said the sportscar highlights the Hiroshima-based automaker’s innovation in design. Its shape developed from studies of sheer fabric fluttering in the wind, and its interior was based on “koinobori,” or carp-shaped decorations of cloth that Japanese put up to sway in the wind to celebrate Children’s Day, a national holiday, said Chief Designer Atsuhiko Yamada. “Air is a very important substance, but it is invisible,” he said in explaining the design challenges. Mazda has been marking growing sales at a time when some automakers, including Ford Motor Co., has been struggling to make a turnaround amid faltering sales and cost cutting. Mazda’s global sales for the current fiscal year is expected to be up 4 percent to a record high 1.35million vehicles, surpassing the company’s previous record set in 1990, as it boosts vehicle sales in North America and Europe, offsetting flat sales in Japan.160Want local news?Sign up for the Localist and stay informed Something went wrong.

San Pedro detention center loses accreditation

first_img AD Quality Auto 360p 720p 1080p Top articles1/5READ MOREGame Center: Chargers at Kansas City Chiefs, Sunday, 10 a.m.Citing agency policy, the official declined to release the inspection report or elaborate on why the facility failed the renewal inspection, done every three years. Immigration and Customs Enforcement spokeswoman Virginia Kice confirmed the lost accreditation, but said it was not related to detainee care – an issue that’s drawn criticism and lawsuits. “It was a facility maintenance issue,” said Kice, who declined to elaborate. Kice said the problem was corrected, and the agency planned to apply for reaccreditation early next year. The facility is still operating, and it was unclear what continued loss of accreditation could mean for it long-term. The immigration detention facility in San Pedro, one of several nationwide to come under scrutiny from immigrant and civil-rights groups, has lost its accreditation. The center houses several hundred illegal immigrants who have been detained by U.S. Immigration and Customs Enforcement and are facing deportation. The facility lost accreditation in August after failing to comply with mandatory standards, an official with the Alexandria, Va.-based American Correctional Association told The Associated Press. The official spoke on the condition of anonymity because he was not authorized to make public comments. Accreditation is important for immigration and other correctional facilities because it shows that national standards of care have been met, provides arguments against lawsuits and can reduce liability and insurance costs. Ranjana Natarajan, an attorney with the American Civil Liberties Union of Southern California, said immigration facilities strive for accreditation, so having it revoked was significant. “We don’t yet know the specific reason” for losing it, she said. “But we do know there are serious problems at San Pedro.” The San Pedro facility came under sharp criticism last summer when a transgender Mexican immigrant with AIDS being housed there died while in custody. The family claimed Victor Arellano was improperly denied medical attention, a contention immigration officials rejected. In recent years, the ACLU and other groups have sued ICE over several detention facility issues, ranging from alleged inadequate access to health care to prolonged detention. A lawsuit filed by the ACLU in June, aiming to stop immigration authorities from forcibly drugging deportees, cited an immigrant allegedly drugged at the San Pedro facility.160Want local news?Sign up for the Localist and stay informed Something went wrong.

DONEGAL MAN SUES NEWSPAPER WHICH CLAIMED HE WAS A ‘HEADCASE’

first_imgA Donegal businessman claims a newspaper article about him filming the birth of his baby daughter wrongly portrayed him as “some kind of headcase running around with a camera.”John McCauley (46), who is involved in property and construction, told a High Court jury he was disgusted by the article written by columnist Brenda Power in the Sunday Times in 2009.The article arose out of a separate action brought by Mr McCauley in which he sued the midwife and the hospital where the birth took place over the interruption of his filming by the midwife. He claimed he had got permission from the doctor to film and that his partner, Jurgita Jachimaviciute, who gave birth to their first child Simone that night, had requested he film it.He lost that action against the hospital and Ms Power later wrote a comment piece about the case.In his defamation action before a judge and jury of eight women and four men, Mr McCauley claims the article meant he showed no consideration or care for his partner and the baby.He also claims it meant he failed to reassure or comfort his partner in what was alleged by the paper to be an emergency situation but which he says was not the case. He also says it meant he was motivated by self-interest with no appreciation for his role in the delivery of the baby.The defendants deny the claims and say the article was true, fair comment and enjoyed qualified privilege.Mr McCauley, a plasterer by trade who is originally from Donegal but now living in Lithuania with his partner and two children, told the court that on the night of the birth, staff at the hospital appeared to change shift and the midwife who came on was very abrupt and uncommunicative.Only that his partner was so close to giving birth, he said he would have asked for someone else to attend, he said. When the midwife asked him to stop filming, he said he would rather not but she asked him again and he did.Mr McCauley said there was a lot of publicity about the court case he took against the hospital which he lost in February 2009.On March 1st that year, he read Ms Power’s article and said he could not believe it.“I could not believe someone who obviously knew nothing about the court case or about what led to the case could write such a lot of nonsense… I was disgusted at the way she portrayed me as some some kind of headcase running around with a camera”.Mr McCauley denied a suggestion in the article there was an emergency situation during the delivery. It was not an emergency because a decision had been taken much earlier in the evening to deliver by C-section and the child was not born till 11.10pm, he said.He said almost everything in the article was untrue except the fact he had lost his case against the hospital. He felt very angry and sad particularly as he had got comments about it from people in Ireland, Lithuania, Dubai and Turkey.Earlier his counsel Colm Smyth SC told the jury the article was an “outrageous and malicious” piece of journalism and the jury should award aggravated damages. The hearing continues.DONEGAL MAN SUES NEWSPAPER WHICH CLAIMED HE WAS A ‘HEADCASE’ was last modified: July 11th, 2013 by StephenShare this:Click to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window)Click to share on LinkedIn (Opens in new window)Click to share on Reddit (Opens in new window)Click to share on Pocket (Opens in new window)Click to share on Telegram (Opens in new window)Click to share on WhatsApp (Opens in new window)Click to share on Skype (Opens in new window)Click to print (Opens in new window) Tags:cameraJOhn McCauleynewspaperpropertySunday Timeslast_img read more

Vipers SC priced out of deal for Yunus Sentamu

first_img Tags: AS VitaCHAN 2014FC IIvesKF TiranaSt Mary’s Kitendetopvipers scYunus Ssentamu Sentamu is currently a free agent after his contract at Tirana expired. (PHOTOS/Courtsey)KAMPALA – Yunus Sentamu broke to prominence at the 2014 African Nations Championship in South Africa.The then 19-year-old who was playing at Vipers SC finished as the joint second top scorer at the tournament with three goals, one behind South Africa’s Bernard Parker.On course for greatness, Sentamu moved to AS Vita of DR Congo but after a troubled first year, he transferred to Tunisian side CS Sfaxien.At Sfaxien, he also lasted a single year, scoring four goals in 13 games before sealing a move to FC IIves of Finland.Once again, IIves could not provide a home safe enough for Sentamu as he moved to Albani’s KF Tirana after just a single season.At Tirana, the St. Mary’s Kitende graduate looked to have finally settled as he spent two uninterrupted years in Albania’s capital.However, earlier this year, his two-year deal expired and both parties opted not to renew it.Ssentamu has in the recent past been in Uganda and reliable sources indicate he has been in negotiations with Kitende based side, Vipers SC over a possible return to the St.Mary’s Stadium.However, it is understood that the Venoms have pulled out of the deal after the 24-year-old asked for huge wages.Ssentamu who started his youth-football at St. Julian Secondary School was demanding for $4000 (Approximately UGX 15m), per month, a sum Vipers are not willing to offer him.Sentamu is understood to have been asking for $4000 per month as salary.With the expected move to Vipers now having fallen through, Ssentamu is seeking to secure a deal in Europe once again.Whether he lands it before the start of the upcoming season (2019/20), remains to be seen.One this is for certain, he is a player who promised so much in the beginning but one on course to delivery so little in the end due to the fact that for some reason, he has failed to settle in one place and better his career.Currently, he has played 13 full international games for the Uganda Cranes, scoring four goals.Comments last_img read more

5 held in connection with killing, gang rape off Yamuna Expressway

first_img The police came to know through media reports that the woman suspected the role of neighbours and detained the men late on Thursday night, said Jewar Police Station in charge Rajpal Tomar.According to the police, the woman later clarified that she named the neighbour(s) out of sheer anger. With this set of neighbours, the police have figured out a property related dispute between the two families.On the progress of the probe thus far, the police said the gangs active on the Yamuna Expressway and adjoining areas remained the prime suspects for them.“We will get a final statement recorded before the magistrate on Saturday,” added Mr. Tomar.Several teams are probing the incident that took place in a field alongside the road linking Jewar to Bulandhahr, barely 1.2 km off the Yamuna Expressway. A scrap dealer was shot dead and the four women were gang-raped by a group of six men. They also allegedly took away cash and jewelleryThe special task force officers were not available for comments. ‘They pulled the trigger and silenced him’ A special task force of the police on Friday afternoon picked up five men for questioning in connection with the gunning down of a man, gang rape of four women and alleged robbery in a field off the Yamuna Expressway in Uttar Pradesh in the early hours of Thursday. Police had detained the five for questioning on Thursday night, but let them off later.  Initially, police said, the five were questioned because one of the women told media that she had identified three of the six assailants as her neighbours. She, however, retracted the statement a day later.The FIR that was registered on the statement of one of the men in the vehicle in which seven others, including the women, were travelling said the suspects were stranger to them and the women could recognise them.Also Readlast_img read more

Over 15,000 people relocated in Gujarat

first_imgAfter Saurashtra, its now the turn of the North Gujarat region to bear the brunt of incessant rainfall. Heavy flooding in several areas has forced the State authorities to shift people out of low lying areas. Several hundred stranded people have been rescued.On Monday, the authorities relocated more than 15000 people in North Gujarat districts, mostly in Banaskantha, to safer areas. The NDRF, Air Force, BSF and the Army were joined by other agencies in the rescue of more than 500 stranded people.The State continues to be on high alert as the meteorological department has forecast more rains. Gujarat Chief Minister Vijay Rupani conducted two aerial surveys and held meetings with officials. He also briefed Prime Minister Narendra Modi on the situation. He asked the district administration to accord top priority to rescuing people stranded in flood waters and shifting those in low lying areas.Meanwhile, the continuing rainfall affected the rescue work of the Indian Air Force. Many of its choppers could not take off and those that did were forced to return to the base.A Defence aircraft loaded with relief material and food packets had to return due to heavy rains in the target areas in Banaskantha district. The district administration has sounded a high alert and advised people not to venture out. Schools and colleges have been asked to to remain closed on Tuesday.Seven persons have died in ran related incidents since July 20, while the death toll since the beginning of monsoon has touched 72.Trains cancelledThe Ahmedabad-Delhi Rajdhani Express has been cancelled due to the break-down of tracks in Palanpur.

Half of Earth’s water formed before the sun was born

first_imgGood news for hunters of extraterrestrial life: Water may be more widespread in planetary systems than previously thought. A team of researchers studying the origin of the water in our solar system has concluded that up to half of it formed before the sun itself was born—that is, in the cloud of dust and gas that was the progenitor of our solar system. If water can form in abundance in such clouds, then it may be found everywhere.Our solar system is awash with water. Apart from Earth, water is found on the moon, Mars, Mercury, comets, and the icy moons of the giant planets. But where did it come from? Water is known to form in the clouds of gas and dust of the interstellar medium (ISM) from which planetary systems coalesce, but is it destroyed when the newly formed sun starts pumping out heat and light, only to be formed again later? Or does that primordial water survive star formation and remain around us today?To answer that question, a team led by astronomer L. Ilsedore Cleeves of the University of Michigan, Ann Arbor, focused on deuterium, a heavy form of hydrogen that was created in the big bang along with normal hydrogen. There are about 26 deuterium atoms for every million hydrogen atoms across the universe, but it is six times as prevalent in the water on Earth and in other solar system bodies. Scientists conclude that when the water formed, the reaction creating deuterium-rich “heavy water” was slightly faster than the one creating normal water, so the proportion of deuterium in water increased.Sign up for our daily newsletterGet more great content like this delivered right to you!Country *AfghanistanAland IslandsAlbaniaAlgeriaAndorraAngolaAnguillaAntarcticaAntigua and BarbudaArgentinaArmeniaArubaAustraliaAustriaAzerbaijanBahamasBahrainBangladeshBarbadosBelarusBelgiumBelizeBeninBermudaBhutanBolivia, Plurinational State ofBonaire, Sint Eustatius and SabaBosnia and HerzegovinaBotswanaBouvet IslandBrazilBritish Indian Ocean TerritoryBrunei DarussalamBulgariaBurkina FasoBurundiCambodiaCameroonCanadaCape VerdeCayman IslandsCentral African RepublicChadChileChinaChristmas IslandCocos (Keeling) IslandsColombiaComorosCongoCongo, The Democratic Republic of theCook IslandsCosta RicaCote D’IvoireCroatiaCubaCuraçaoCyprusCzech RepublicDenmarkDjiboutiDominicaDominican RepublicEcuadorEgyptEl SalvadorEquatorial GuineaEritreaEstoniaEthiopiaFalkland Islands (Malvinas)Faroe IslandsFijiFinlandFranceFrench GuianaFrench PolynesiaFrench Southern TerritoriesGabonGambiaGeorgiaGermanyGhanaGibraltarGreeceGreenlandGrenadaGuadeloupeGuatemalaGuernseyGuineaGuinea-BissauGuyanaHaitiHeard Island and Mcdonald IslandsHoly See (Vatican City State)HondurasHong KongHungaryIcelandIndiaIndonesiaIran, Islamic Republic ofIraqIrelandIsle of ManIsraelItalyJamaicaJapanJerseyJordanKazakhstanKenyaKiribatiKorea, Democratic People’s Republic ofKorea, Republic ofKuwaitKyrgyzstanLao People’s Democratic RepublicLatviaLebanonLesothoLiberiaLibyan Arab JamahiriyaLiechtensteinLithuaniaLuxembourgMacaoMacedonia, The Former Yugoslav Republic ofMadagascarMalawiMalaysiaMaldivesMaliMaltaMartiniqueMauritaniaMauritiusMayotteMexicoMoldova, Republic ofMonacoMongoliaMontenegroMontserratMoroccoMozambiqueMyanmarNamibiaNauruNepalNetherlandsNew CaledoniaNew ZealandNicaraguaNigerNigeriaNiueNorfolk IslandNorwayOmanPakistanPalestinianPanamaPapua New GuineaParaguayPeruPhilippinesPitcairnPolandPortugalQatarReunionRomaniaRussian FederationRWANDASaint Barthélemy Saint Helena, Ascension and Tristan da CunhaSaint Kitts and NevisSaint LuciaSaint Martin (French part)Saint Pierre and MiquelonSaint Vincent and the GrenadinesSamoaSan MarinoSao Tome and PrincipeSaudi ArabiaSenegalSerbiaSeychellesSierra LeoneSingaporeSint Maarten (Dutch part)SlovakiaSloveniaSolomon IslandsSomaliaSouth AfricaSouth Georgia and the South Sandwich IslandsSouth SudanSpainSri LankaSudanSurinameSvalbard and Jan MayenSwazilandSwedenSwitzerlandSyrian Arab RepublicTaiwanTajikistanTanzania, United Republic ofThailandTimor-LesteTogoTokelauTongaTrinidad and TobagoTunisiaTurkeyTurkmenistanTurks and Caicos IslandsTuvaluUgandaUkraineUnited Arab EmiratesUnited KingdomUnited StatesUruguayUzbekistanVanuatuVenezuela, Bolivarian Republic ofVietnamVirgin Islands, BritishWallis and FutunaWestern SaharaYemenZambiaZimbabweI also wish to receive emails from AAAS/Science and Science advertisers, including information on products, services and special offers which may include but are not limited to news, careers information & upcoming events.Required fields are included by an asterisk(*)But that enrichment of deuterium happens only under certain conditions: It has to be very cold (only a few tens of degrees above absolute zero), plus you need oxygen and some sort of ionizing radiation to get the reaction going. All of those things are available in the ISM. The ionizing radiation there is cosmic rays, particles from distant sources that zip through space at high speed. And astronomers have observed water in the ISM that is highly enriched in deuterium, so that could be source of the solar system’s water.Still, there’s a question mark over whether this interstellar water could survive the violence of the sun’s birth. To find out, Cleeves and her colleagues sought to determine whether the same water-forming reactions could have occurred after the sun’s formation, in the protoplanetary disk of gas and dust from which planets form. Such a disk would offer low temperatures and an oxygen supply just as the ISM does, but would there be enough ionizing radiation?The team constructed a detailed model of the chemical processes creating water in a protoplanetary disk. Much of the cosmic rays are fended off by the young star’s magnetic field and particles streaming out from the star, but there are other sources of radiation: x-rays from the star and short-lived radionuclides in the disk. As the researchers report online today in Science, those sources of radiation just don’t produce heavy water fast enough. “We found that heavy water didn’t form in any abundance over a million years,” Cleeves says.In fact, the team estimates that as much as 50% of the water now on Earth may have existed since before the birth of the sun 4.5 billion years ago. And that’s good news for other planetary systems. The conditions in the ISM are far more uniform across space than those in protoplanetary disks, so it’s likely that there is water everywhere waiting for planets to form. “As the number of confirmed planetary systems increases, it’s reassuring that … water is available,” Cleeves says.“This is a very interesting result. We’ve been debating this for years, whether or not the ices have an interstellar heritage,” says astrophysicist Karen Willacy of NASA’s Jet Propulsion Laboratory in Pasadena, California. She says that other groups have tried to model the collapse of clouds in the ISM into planetary systems to see if ice would survive, but “with various results, that don’t always agree,” Willacy says. “This is much more simple approach, just using the chemistry which is well understood.”last_img read more
