New research suggests 3-D photography could offer better orthodontic diagnosis using less radiation

first_imgCommon orthodontic problems such as crossbite, overbite, underbite, and crowding of the teeth can have a negative impact on a person’s physical appearance, dental function, and overall self esteem. To make a diagnosis and plan treatment, orthodontists currently take multiple x-ray images of the entire skull before, during and after orthodontic treatment. Part of the skull, the cranial base, is used as a stable reference for determining the position and orientation of the jaws and teeth when planning treatment changes. While the amount of radiation is small, x-rays of the whole skull taken multiple times during treatment can be a concern, especially for pediatric patients who are generally more susceptible to the harmful effects of ionizing radiation than adults.A recent study published in the European Journal of Orthodontics, suggests that another approach using non-radiographic 3-D dental photogrammetry could offer accurate dental and facial measurements based on using the eyes and natural head orientation as references rather than the cranial base.Mohamed Masoud, director of Orthodontics in the Department of Developmental Biology at the Harvard School of Dental Medicine, along with his research team studied 180 females and 200 males between the ages of 18 and 35 using 3-D facial and dental imaging to produce an adult sample with near ideal occlusion and a pleasing facial appearance. The goal was to provide reference values that can aid practitioners in determining the relative position and orientation of a patient’s dental and facial structures without exposing the cranium to radiation.

Brazilian Armed Forces Conduct Joint Border Operation

first_imgBy Taciana Moury/Diálogo December 05, 2018 The border area along the Brazilian states of Mato Grosso, Mato Grosso do Sul, Paraná, and Santa Catarina served as the staging ground for security operation Ágata Graal, September 24-28, 2018. The initiative sought to curb drug trafficking, smuggling, and other illegal transnational activities along the 3,500-kilometer border with Bolivia, Paraguay, and Argentina. Operation Ágata is of a continuous nature and is carried out throughout the year in different border regions. The initiative projects preventive operations along the border via air, land, and river patrols. Service members set up checkpoints at river channels and main roads, conduct airstrip and port surveillance, and search vessels, motor vehicles, people, and aircraft. The objective is to step up government’s presence and integrate the activities of the Armed Forces with other federal, state, and municipal agencies responsible for the region’s security. Operation Ágata Graal, a name it acquired in the latest 2018 edition, was unprecedented due to the joint effort with the Brazilian Navy (MB, in Portuguese), Army (EB, in Portuguese), and Air Force (FAB, in Portuguese). Ágata Graal’s headquarters was setup in the city of Cascavel, in Paraná state, in the heart of the border area. There, service members patrolled air, land, and rivers simultaneously. FAB also coordinated aerial support from Aerospace Operations Command in Brasília. According to MB Admiral Ademir Sobrinho, head of the Armed Forces Joint Chief of Staff, previous operations had simpler formats and were developed quickly and more suddenly. “The joint work was limited to a strategic and operational structure, and when it was time for the tactical part, each force would operate separately,” Adm. Ademir said. Public security agencies such as the Federal Police, the Federal Highway Police (PRF, in Portuguese), the Brazilian Internal Revenue Service, and the military police from the states of Paraná and Mato Grosso do Sul took part in the interagency operations. A total of 3,000 service members and civilians, about 40 aircraft, and 1,000 different armored vehicles and boats participated. According to FAB Lieutenant General Ricardo Cesar Mangrich, commander of Ágata Graal, the biggest challenge was to assemble a structure to cover such an extensive and diversified border. “We had Lake Itaipu, at the border with Paraguay, where shores allow for the construction of paths used to board small boats that can carry illegal goods,” Lt. Gen. Mangrich told Diálogo. “We also had the Paraná-Tietê waterway, between Brazil’s southern and southwestern regions, which serve as a gateway into the country, near the state of São Paulo, a highly developed region. Lastly, the dry and complex border of Mato Grosso do Sul, with small roads every 200 meters, made control very difficult.” Joint task forces A general staff consisting of 40 officers from the three branches coordinated operations of the joint task forces created to patrol each area. The objective was to advise the commander according to the characteristics of each branch to optimize the use of available resources. “We used armored vehicles, subunits of EB’s motorized cavalry, FAB aircraft, and other resources,” said Lt. Gen. Mangrich. “The Joint Chief of Staff’s advice was essential to ensure interoperability, and avoid friendly fire from our service members operating side by side on the ground.” Service members conducted Ágata Graal’s operations at night to ensure the element of surprise, since these were not covert. “The troop got to the point where the opponent could not operate at night, which created instability and an extremely positive result,” Lt. Gen. Mangrich said. Air assets used heat sensors and satellites for monitoring and reconnaissance activities, and a command and control system to analyze and interpret the images. The information obtained contributed to the commander’s decision making for troops’ engagement. “During a night flight, a FAB aircraft identified the entry of illegal goods. The satellite provided a visual revealing the number of recipients waiting for the merchandise. Our special forces troops were ready for action at the location. We opted to avoid confrontation and prevent having many fatalities. We chose to throw a stun grenade to disperse the people and stop the illegal activity,” said Lt. Gen. Mangrich. Results For the officer, the operation helped confirm the implementation of a successful operational model that can be used when necessary. “We managed to close the border by sea, land, and air during the operation,” said Lt. Gen. Mangrich. Effective to protect borders, the operation also increased interoperability between forces and coordination with participating agencies. A command and control structure facilitated the coordination of well-organized efforts and efficient results. According to Adm. Ademir, Ágata Graal allowed service members to uncover river and land routes, and docks criminal organizations used in the area, as well as their modus operandi. “We nearly completely stopped drug and arms trafficking, and cross-border crimes,” Adm. Ademir said. “After we left the location, the Federal Highway Patrol broke arrest records,” said Lt. Gen. Mangrich. “We identified trucks gathered across the border and a possible route for illegal entry into the country with satellite help. As soon as the operation ended, they tried to enter and PRF was ready for action.”last_img read more

Two hospital directors die of COVID-19 as Indonesian doctors call for transparency

first_imgThe Indonesian Medical Association (IDI) has announced that two more doctors died after contracting the COVID-19 coronavirus during their service battling the pandemic.IDI spokesperson Halik Malik said that Efrizal Syamsudin, the director of Prabumulih General Hospital in South Sumatra, died on Monday at Mohammad Hoesin General Hospital in Palembang, South Sumatra. He was declared to be a patient under close monitoring (PDP) for the disease and his test results, which came after his passing, were positive for COVID-19.“[Efrizal’s death] has been confirmed to the head of South Sumatra’s chapter of IDI. Based on that report, IDI offers [our] condolences and appreciation for the service of our colleagues,” Halik told The Jakarta Post on Tuesday.Ratih Purwarini, the director of Duta Indah Hospital in North Jakarta, died on Tuesday at the Pelni General Hospital in West Jakarta after showing symptoms of COVID-19 before her death.Halik said that she was previously admitted to Eka Hospital in Serpong, South Tangerang, where her COVID-19 test results later came back positive. “The regional chapters of IDI said that the two doctors are very dedicated to leading their respective hospitals, including taking part in their hospitals’ vigilance and response measure to the coronavirus outbreak,” he said.IDI said that 12 doctors, all of whom were its members, have died since the country started getting COVID-19 cases. The government announced the first two cases of COVID-19 in the country on March 2. There have been 1,677 cases that resulted in 157 deaths and 103 recoveries as of Wednesday.“Out of the 12, 11 of them either tested positive or were being observed for COVID-19, while one died of exhaustion while handling the pandemic,” he saidDoctors and medical workers are at high risk of contracting the disease as they tend patients and suspects on a regular basis. The scarcity of personal protective equipment (PPE), such as masks, gloves and hazmat suits, in the country leaves them more exposed to the disease.Read also: COVID-19: Inadequate medical supplies take toll on lives of Indonesian medical workersThe government has taken several measures to distribute PPE to hospitals and other healthcare units and prioritizes COVID-19 rapid testing for medical workers. It also provides updates on the number of cases, deaths and recoveries every day.Halik, however, asked the government to provide more detailed information regarding positive and tested patients. “We really emphasize that the data of medical staff, at least in professional organizations such as doctors and other health professionals, can be provided by the government so each of the organizations can take measures,” he added.Topics :last_img read more

Tiger King’s Carole Baskin of Tampa Tricked Into Video Interview

first_imgCarole Baskin has made her first ever video interview since the NetFlix “Tiger King” series blew up. It turns out the appearance was part of a prank by two YouTubers, Josh Pieters and Archie Manners. Pieters and Manners pretended to be from a production company which books celebrities for The Tonight Show with Jimmy Fallon. At first, Baskin who runs the Big Cat Rescue sanctuary in Tampa, declined, but did commit to it later only if the interview would be about big cats and not about whether or not she allegedly had her second husband, Don Lewis, killed. The two YouTubers put together clips of Fallon asking questions for the interview, but explained to Baskin she wouldn’t be able to see him because he was filming at his home.Baskin shared she’s been keeping busy during quarantine taking care of the big cats with her daughter at the Big Cat Rescue sanctuary.last_img read more

Brazil 2014 missing stars

first_imgIbrahimovich, Cech, Alaba top list of stars who will not be going to Brazil for the biggest football Mundial.PETR CECH:CZECH  REPUBLICCech played in every minute of his nation’s group stage qualifying campaign but was unable to secure their place in Brazil. The Chelsea shot-stopper conceded nine goals in ten matches as his side finished third in the group, a point behind Denmark and seven behind leaders, Italy.BRANISLAV IVANOVIC:  SERBIAAnother Chelsea man, another disappointing World Cup quest. He played all ten of his nation’s group games,scoring once, as four away defeats cost a strong side a chance to shock the world next summer.NEVEN SUBOTIC:SERBIAHis disappointment at Serbia’s struggle to finish higher than third in Group A was compounded after it was confirmed recently that he will miss the rest of the season with a serious knee injury. The Borussia Dortmund man played in just four of his nation’s ten group games.DANIEL AGGER:DENMARKThe Liverpool man might have found it hard to crack the Reds’ lineup this season but was his usual mainstay with Denmark, playing nine qualifiers and tallying four goals. Ultimately, the Danes’ lack of firepower meant their 16-points haul wasn’t enough to reach the playoffs; Agger led his nation in scoring. What more can one man do?DAVID ALABA:AUSTRIAAlaba has been unable to replicate the success he has enjoyed with his club Bayern Munich, at the international level. Despite his six goals, Austria fell short in their quest to reach Brazil next year, finishing third in Group C, three points behind Sweden, who went on to lose to Portugal in the playoffs. MAREK HAMSIK:SLOVAKIAThere would be no repeat of 2010’s World Cup heroics this time around as Slovakia fell disappointingly short, finishing third in Group G with 13 points, nowhere near group-topping Bosnia-Herzegovina or playoff-winning Greece (both on 25 pts). Scoring just 11 goals in 10 games against the likes of Lithuania and Liechtenstein was the root of their downfall, with Hamsik’s two goals in 686 minutes far below the high standards he sets weekly at Napoli. MARTIN SKRTEL:SLOVAKIANo repeat of the heroics that took Slovakia to their first World Cup in South Africa 2010. Another Liverpool defender who can put his feet up.Skrtel’s strong defensive display will be  missed in Brazil.Slovakia’s were disappointing all over,failing to defend well and also scored a paltry 11 goals in 10 qualifying games.ALEKSANDAR KOLAROV:SERBIAWrapping up a dismal qualifying campaign for Eastern European defences is Kolarov who moved to Manchester City after South Africa 2010 but will be staying at home next summer.He and the likes of Branislav Iva novic and Neven Subotic failed to steer Serbia to a second consecutive World Cup appearance.LUKASZ PISZCZEK:POLANDAnother Borussia Dortmund man on the list.Piszczek played all three games for Poland in their campaign at the last European Championship which they  co-hosted with neighbours Ukraine.This time around, he won’t play any at the Mundial as Poland could only manage third place in a group that was won by England.ARDA TURAN:TURKEYA fourth-place finish in Group D behind the Netherlands, Romania and Hungary was a poor return for Fatih Terim’s side, especially as they sat in a playoff spot before the final group game, then lost 2-0 to the Dutch. As the side’s playmaker, Atletico Madrid’s Turan scored once in his nine group appearances. HENRIK MKHITARYAN: ARMENIA  The Borussia Dortmund maestro has impressed in the Bundesliga this season but remains hampered at the international level by one of Europe’s weaker teams. Mkhitaryan played every minute of qualifying and inspired impressive results such as the 2-2 draw vs. Italy in Naples, but it wasn’t enough.ANDRIY YARMOLENKO: UKRAINEThe Dynamo Kiev forward cum winger will miss out on his first World Cup appearance following a 3-2 aggregate loss to France.He will have to wait for another four years before having a chance to play at the Mundial.No doubt the world will miss this talented star.CHRISTIAN ERIKSEN: DENMARKThe good news for the Spurs midfielder, his ankle injury should only keep him out for four weeks. The bad news? No Brazilian adventure to demonstrate his creative talent.The talented midfielder has set the English game alight since his move from Dutch side, Ajax Amsterdam. AARON RAMSEY:WALESThe in-form Arsenal midfielder,Aaron Ramsey, missed out as Belgium and Croatia proved to be too strong in their qualification section.He and his international colleague, Gareth Bale, will have to wait for another four years before they can fulfil their ambition of playing at the Mundial.GYLFI SIGURDSSON: ICELANDIceland came close to making it to Brazil qualifying second behind Switzerland in a group that has Slovenia,Norway, Albania and Cyprus.His side just wasn’t strong enough to outlast the dangerous Croatians in a playoff. The Tottenham HotspursPAPISS CISSE :SENEGALRight out of form for his club and now he has to share dressing room with Newcastle team-mate, Cheick Tiote, whose Ivory Coast side qualified at Senegal’s expense. Senegal were undone once again by the Ivoriens who knocked them out of the qualifying race for the 2013 Africa Cup of Nations in South Africa.Cisse and co will miss the chance of emulating the Terangha Lions 2002 who shocked the world by going as far as the quarter-final. ROBERT LEWANDOWSKI: POLANDA Polish side in transition couldn’t keep pace in Group H, starting strong but ultimately finishing fourth on 13 points, with defeats to Ukraine and England in their final two group games,leaving observers wondering what could have been. The Dortmund striker’s return was more modest than at the club level, notching three goals in nine qualifying games (809 minutes).ZLATAN IBRAHIMOVIC: SWEDENThe PSG, all-world star did his best in an epic playoff battle with Portugal before succumbing to the singular genius of Cristiano Ronaldo. What more could his nation ask of him? Finishing second to a near-perfect German side in Group C, Ibra scored eight of his side’s 21 goals in qualifying, setting up countless others. He will miss out, but with his head held high.GARETH BALE:WALESThe Real Madrid star isn’t the first Welsh legend to miss a World Cup — with the team having been only once, in 1958, the likes of Ryan Giggs, Mark Hughes, Neville Southall, John Toshack and Gary Speed never saw one, either — but fans and pundits alike would have expected a better return than fifth place in Group A this time around. Bale led his team in scoring (four goals) despite playing just seven games, insufficient to avoid finishing behind Belgium, Croatia, Serbia and even Scotland.MOHAMMED SALAH:EGYPT Egypt’s elimination means the World  will be deprived of the exciting talents of Mohammed Salah.The former African Champions lost 7-3 on aggregate to the Black Stars of Ghana and the implication of that is, Sallah who scored a wonderful goal in Swiss side, FC Basle champions League shocking victory against Chelsea at the Stamford Bridge, won’t feature in Brazil 2014.MOHAMMED ABOUTREIKA: EGYPTEgypt legend,Mohammed Aboutrika  won’t be on the plane to Brazil which probably is his last chance to play at the World Cup.No doubt he will go down in history as one of the most talented footballers never to have played at the Mundial.last_img read more

Father charged after bending baby backwards until he heard a pop

first_imgA father from Arizona is now facing child abuse charges after he reportedly injured his 1-month-old daughter by bending her backward until he heard a popping sound.Officials say they were alerted to the incident after the father took the child to Phoenix Children’s Hospital and the medical staff examining her found that the child had extreme injuries from both the past and the present.The father, 22-year-old Adan Flores told medical staff that the child was injured after a relative accidently sat on her, however, doctors reported that none of the injuries matched what Flores told them.According to the report, the 1-month hold had  fractured legs, a damaged liver, hemorrhaging eyes, and bleeding from her mouth.  In addition to that, the child also had multiple recent and healing fractures on her ribs.When authorities spoke to Flores he admitted that he put the baby on a bed on her knees and bent her backwards until he heard a popping sound. He then began squeezing her in an effort to get her to stop crying.He also admitted to twisting her legs until he heard them pop and shoving a thermometer into her mouth.Investigators say Flores then told them that he hesitated to take the child to the hospital initially because he knew DCF would be contacted and that the child’s mother would find out what he did and leave him.The child’s mother was reportedly in the shower at the time of the incident.Flores has since been arrested and charged with six counts of child abuse. His bail has been set at $100,000.last_img read more

NEWLY MARRIED, REFRESHED & READY, WRONA SET TO MAN MICROPHONE FOR SANTA ANITA’S 2016 AUTUMN MEET OPENER ON FRIDAY

first_imgARCADIA, Calif. (Sept. 28, 2016)–There’s a new voice in town. Australian-born Michael Wrona, who was named the Voice of Santa Anita following a rigorous audition process this past winter, is set to handle the full-time announcing duties when Santa Anita’s 23-day Autumn Meet kicks off on Friday, with first race post time at 1 p.m.“I’m ready,” said the popular Wrona, 50, at Santa Anita’s Clockers’ Corner Wednesday morning. “It was a great honor to be named the full-time announcer this past spring and I feel much more at home coming into this meet. Kathy (longtime fiancé) and I got married in Lake Tahoe right after the Spring Meet ended in July and we just spent about five weeks in Australia, which was fantastic.“We’ve closed out our apartment in San Francisco and we’ve finally got everything down here now, so we’re both greatly relieved to be completely moved in and settled. It’s a great feeling and I truly believe we’re in for some world class racing with California Chrome, Beholder and so many other top horses competing here this Saturday and of course, during the two-day Breeders’ Cup on Nov. 4 & 5.”After making his American racing debut at Hollywood Park in 1990 at the tender age of 24, Wrona’s life has been nomadic by any measure, as he’s taken on assignments in Chicago, Texas, Louisiana, the eastern seaboard and most recently, the San Francisco Bay Area over the course of the past 26 years.“I’d like to say that I wouldn’t change anything, but that wouldn’t be entirely true,” said Wrona. “While I’ve had a great time everywhere I’ve been and met a lot of great people, I’ve been wanting the stability that this job offers for a long time now. I really can’t put into words how important this position is to Kathy and I at this point in our lives.“I consider Santa Anita the top track in America and there’s no question the best horses in the world will be competing here over the next six weeks. I can’t wait to get started on Friday.”And neither can Wrona’s many thousands of fans who will anxiously await his signature “RACING!” when the starting gates spring open for race one.For more information on Santa Anita’s Autumn Meet and two-day Breeders’ Cup World Championships on Nov. 4 & 5, please visit santaanita.com.last_img read more

Will Brazil plant corn later than normal in 2020?

first_imgShare Facebook Twitter Google + LinkedIn Pinterest The soybean planting in south-central Brazil is now relatively on pace with historical averages, but irregular rains in September, October and early November resulted in delays in several states. Those delays are not likely to cause yield losses to the soybean crop, but will result in a narrower planting window for the second corn crop (“safrinha”), which is planted right after the soybean harvest. A later-than-normal harvest will lead to a delayed start to the corn planting and, probably, to an extension of the planting season into March.How bad is planting in March? Planting corn in March is not unusual. On the contrary, since the ideal planting window ends in mid-March in several Brazilian regions. But planting in March normally results in more risk, because corn will pollinate under potentially harmful weather conditions: lack of moisture, shorter days and even freezing temperatures in some areas. That’s why farmers are always planning on planting as soon as possible. In normal years, they do plant corn in March, but only in marginal areas, where the yield potential is not exactly high.Half of the area in March By the end of February 2020, however, only 53% of the corn area will have been planted in number-two producer Paraná, according to a study recently finished by AgRural. In 2018, when the second corn crop failed in the state due to dry conditions in areas planted later, 56% of the area had been planted by the end of February. In 2019, when the state established a new record average yield, 71% of the area was already planted as of Feb 28. In northern Paraná, the ideal planting window ends on March 15. But in the west of the state, where the bulk of the soybean delay happened this year, the window is narrower and ends on Feb. 20. In that region, planting in March is extremely risky.Crop failure? Does that mean that Paraná will have a crop failure in 2020? No, it does not. But the 2020 second crop will be riskier, no doubt. The same is likely to happen in São Paulo, Minas Gerais, Mato Grosso do Sul and Goiás, where about half (or more) of the area will have to be planted in March. Mato Grosso The honorable exception will be top producer Mato Grosso, where 90% of the corn area will likely be planted until the end of February 2020 — not far from the 93% planted by the end of February 2019. And, since Mato Grosso represents about 45% of Brazil’s second corn crop production, it seems that the 2020 “safrinha” will not be excessively impacted by the soybean planting delay, after all.Planting intentions AgRural will release its first planting intention numbers for the 2020 second corn crop in mid-December. The narrower planting window might make farmers think twice before expanding acreage. Very strong prices in Brazilian reais, on the other hand, buoyed by record exports, a thriving meat industry and currency devaluation, are likely to give the area a boost.In 2019, Brazil produced 73.2 million metric tons of corn in the second crop. It was its best “safrinha” ever, which led Brazilian total production (first, second and third crops combined) to reach the 100 million ton figure for the first time.last_img read more
