Materials scientists find better model for glass creation
Harvard materials scientists have come up with what theybelieve is a new way to model the formation of glasses, a type of amorphoussolid that includes common window glass.Glasses form through the process of vitrification, in whicha glass-forming liquid cools and slowly becomes a solid whose molecules, thoughthey’ve stopped moving, are not permanently locked into a crystal structure.Instead, they’re more like a liquid that has merely stopped flowing, thoughthey can continue to move over long stretches of time.“A glass is permanent, but only over a certain time scale.It’s a liquid that just stopped moving, stopped flowing,” said David Weitz,Mallinckrodt Professor of Physics and Applied Physics in Harvard’s School ofEngineering and Applied Sciences (SEAS) and the Department of Physics. “Acrystal has a very unique structure, a very ordered structure that repeatsitself over and over. A glass never repeats itself. It wants to be a crystalbut something is preventing it from being a crystal.”Other than window glass, made from silica or silicon dioxide,Weitz said many sugars are glasses. Honey, for example, is not a glass at roomtemperature, but as it cools down and solidifies, it becomes a glass.Scientists such as Weitz use models to understand theproperties of glasses. Weitz and members of his research group, together withcolleagues at Columbia University and the University of North Texas, report inthis week’s Nature a new wrinkle on an old model that seems to improve how wellit mimics the behavior of glass.The model is a colloidial fluid, a liquid with tinyparticles, or colloids, suspended evenly in it. Milk, for example, is afamiliar colloidial fluid. Scientists model solidifying glasses using colloidsby adding more particles to the fluid. This increases the particles’concentration, making the fluid thicker, and making it flow more slowly. Theadvantage of this approach to studying glasses directly is size, Weitz said.The colloid particles are 1,000 times bigger than a molecule of a glass and canbe observed with a microscope“They’re big; they’re slow. They get slower and slower andslower and slower,” Weitz said. “They don’t behave like a fluid. They don’tbehave like a crystal. They behave in many ways like a glass.”The problem with traditional colloids used in these models,however, is that they often rapidly solidify past a certain point, unlike mostglasses, which continue to flow ever more slowly as they gradually solidify.Weitz and colleagues created a colloid that behaves more like a glass in thatway by using soft, compressible particles in the colloid instead of hard ones.This makes the particles squeeze together as more particles are added, makingthem flow more slowly, but delaying the point at which it solidifies, giving ita more glasslike behavior.By varying the colloidal particles’ stiffness, researcherscan vary the colloidal behavior and improve the model’s faithfulness to variousglasses.“There’s this wealth of behavior in molecular glass and wenever saw this wealth of behavior in colloid particles,” Weitz said. “The factyou can visualize things gives you tremendous insight you can’t get withmolecular glass.”
To prune or not to prune, that is the question. Pruning is an important part of maintaining plant health and maximizing plant productivity. This is often a topic that brings fear and confusion, but pruning is, in fact, a beneficial and routine task.Ornamental plants in the home landscape are pruned for several reasons, including maintaining a desired size or shape; promoting healthy, vigorous growth, flowering or fruiting; and removing sections damaged by insects, disease or weather. Each plant in the landscape has its own growth habit and different requirements for pruning. Some shrubs have dwarf growth habits and may never require pruning, while vigorous, large-growing shrubs may require frequent pruning. Anyone can prune, but not everyone prunes properly.Improper pruning, or pruning at the wrong time of the year, can result in misshapen plants, reduced flowering or plants that are more likely to be damaged by insects, diseases or winter cold. Because flowering ornamentals form their flower buds at different times of year, pruning times must be adjusted accordingly.Many spring-flowering plants such as azalea, dogwood, forsythia, redbud and rhododendron set flower buds in the fall, so pruning during the fall or winter months eliminates or decreases their spring flower display.Plants that typically flower during the summer form flower buds on new growth and can be pruned during the winter with no effect on their flowering. However, sometimes plants may need to be pruned outside of these ideal windows to remove damaged or dead plant parts, to remove obstructions from windows or buildings, or to help stop the spread of diseases.As a general rule, plants that flower before May should be pruned after they bloom, while those that flower after May are considered summer-flowering and can be pruned just prior to spring growth.One exception to this rule is the oakleaf hydrangea, a summer-flowering shrub that forms flower buds the previous season.Another exception is late-flowering azalea cultivars, which bloom during May, June or July. Prune both the oakleaf hydrangea and late-flowering azalea cultivars after they bloom. Newer azalea varieties like the ‘Encore’ line, which bloom in the spring, summer and fall, don’t require much pruning — if any at all — as long as they are planted in the right place. At most, you may need to prune taller shoots back into the body of the plant immediately after spring flowering. ‘Knock Out’ roses start flowering in spring up until frost, but should be pruned back to about 12 inches to the ground in early spring, after the threat of last frost has passed, to help stimulate vigorous growth throughout the season.Other types of plants, like broadleaf evergreen shrubs, generally require little or no pruning at all because they usually develop a naturally symmetric growth habit when left alone, but late winter when they are dormant is usually a good time if pruning is desired.Pruning is only harmful to a plant if done incorrectly or at the wrong time. With the right information and confidence, pruning should become a normal part of your landscape maintenance routine.To learn more about pruning ornamental plants, see University of Georgia Cooperative Extension Bulletin 961, “Pruning Ornamental Plants In The Landscape,” and Bulletin 949, “Basic Principles of Pruning Woody Plants,” which can be found at extension.uga.edu/publications.
Board of Governors nominating petitions are due December 17 N ominating petitions for the 2002 elections for the Board of Governors of The Florida Bar must be received in the headquarters office on or before 5 p.m., December 17. Most of the Board positions are for two-year terms. Executive Director John F. Harkness, Jr., on October 1 certified to Thomas D. Hall, clerk of the Supreme Court, the number of members of The Florida Bar in good standing in each of Florida’s 20 judicial circuits and outside the State of Florida, and the number of circuit representatives based on the apportionment formula set forth in rule 2-3.3, Rules Regulating The Florida Bar. Application of the apportionment formula this time resulted in the shift of two seats currently in the 11th Judicial Circuit to the 15th and 20th judicial circuits, respectively. To properly stagger the terms within those circuits, the new 15th and 20th circuits seats will initially be for one-year terms. The loss of two seats in the 11th Circuit will mean that Seats 9 and 10 will no longer exist after June 21, 2002. Since Bar rules provide that no Board member shall serve less than the full term to which elected by reason of any reapportionment, Board member Arthur Rice will be allowed to fill out the remaining year of his term, which expires in June 2003. Pursuant to rule 2-3.4(b), incumbent Board members must advise the executive director of their intention to seek reelection to a new term. The seven Board members who do not plan to run again are indicated by an asterisk next to their names. Nominating petitions for the Board of Governors must be signed by no fewer than five members in good standing whose official bar address is in the same judicial circuit (or out-of-state, if applicable) as the nominee (see form below) or print the downloadable PDF form. Election ballots will be mailed on or about February 25, 2002, and voted ballots must be received prior to midnight, March 21, 2002.

Georgia on Wednesday announced its first confirmed case of the novel coronavirus in the South Caucasus region.”A Georgian national has tested positive for the novel coronavirus,” Health Minister Ekaterine Tikaradze told a news conference, adding that the infected man has been placed in isolation in a Tbilisi hospital.”Three different tests of the 50-year-old man’s nasopharyngeal smear gave positive results, but he is doing well, he is clinically healthy,” head of Georgia’s national center for disease control, Amiran Gamkrelidze told journalists. Topics : The man had arrived in Georgia from Iran via Azerbaijan, Gamkrelidze said.Tikaradze said Georgia would introduce a two-week ban on Iranian nationals entering Georgia, but flatly dismissed fears of a coronavirus epidemic in the ex-Soviet country “at this point”.On Sunday, Georgia’s neighbor Armenia closed its border with Iran and suspended flights as fears over an outbreak of coronavirus in Iran sent neighboring countries scrambling to contain the outbreak.

Yesterday, with no hint from the task force on the next status of the region’s quarantine, Gov. Arthur Defensor Jr. of Iloilo and Gov. Samuel Gumarin of Guimaras issued executive orders extending the MGCQ in their respective provinces. Department of Health (DOH) secretary Francisco Duque III made the announcement. He read IATF-EID Resolution 46-A approved by President Rodrigo Duterte. “Gina-push ta gid ang economic recovery sa Region 6,” he said. The latest to recover was a 34-year-old male from Alimodian, Iloilo. “The right to life prevails. Kinakailangan pangalagaan ang kalusugan ng lahat pero nandiyan din iyong karapatan na magkaroon ng hanapbuhay,” Roque said in a virtual press conference in Malacañang. The President said he would be conferring with businessmen in the days to come for the possible further modification of the community quarantines declared around the country. The IATF-EID recommended the shift of the entire Western Visayas to MGCQ on June 1 for being “low-risk” to COVID-19 infection. Confirmed cases trickling in were mostly returning overseas workers or locally stranded individuals, he pointed out. Mayor Treñas hoped local chief executives would continue their dialogue on how to rev up the local economy slowed down by the COVID-19 pandemic. Treñas, the governors of Antique, Aklan, Capiz, and Negros Occidental were expected to make similar moves following the task force’s announcement last night. As of yesterday, Western Visayas had 147 COVID-19 cases – Aklan, six; Antique, 14; Capiz, six; Guimaras, zero; Iloilo province, 21; Negros Occidental, three; Bacolod City, 11; Iloilo City, 19; and repatriates, 67. ILOILO City – Western Visayas remains under a modified general community quarantine (MGCQ) at least until the end of the month, the Inter-Agency Task Force for the Management of Emerging Infectious Diseases (IATF-EID) announced late last night. * invest in backbone information communications technology (ICT) infrastructure to support electronic governance Earlier yesterday, Presidential Spokesperson Harry Roque said Duterte would be considering the economy as well as the welfare of the Filipino people when deciding on the community quarantine status. Early this week, Mayor Jerry Treñas of Iloilo City expressed confidence that by today, June 16, this city and the rest of Western Visayas would be placed under the “new normal”. According to DOH Region 6, of these cases 101 already recovered while 11 died, leaving the region with 35 active cases. The region shifted to MGCQ on June 1 – a transition phase between GCQ and the “new normal” when restrictions are further relaxed and become less necessary such as limiting people’s movement and public transportation, the operation of industries, and the presence of uniformed personnel to enforce community quarantine. * scale-up production of high-demand products The region has not recorded any new local transmission of the coronavirus disease 2019 (COVID-19), said Treñas. “Sa aton tanan nga mga pumoluyo nagapangabay gid ko nga buloligan naton ini. Tanan kita may kulba. But as I was telling our governors, we all have to live with this in the meantime,” he said. Treñas had a meeting with the provincial governors of the region to map out an economic recovery program. They agreed on five areas of cooperation: “Tomorrow or the day after, after I talk to the businessmen, then we can decide whether or not to modify the lockdown we have imposed,” President Duterte said. He acknowledged the public trepidation on the “new normal” but stressed the need to continue moving forward. * facilitate free movement of people to enable labor mobility and promote domestic tourism * improve health system capacity primarily in COVID-19 testing and contact tracing At the meeting on June 10 at Treñas’ office were governors Arthur Defensor Jr. of Iloilo, Samuel Gumarin of Guimaras, Rhodora Cadiao of Antique, Esteban Evan Contreras of Capiz, Florencio Miraflores of Aklan, Eugenio Jose Lacson of Negros Occidental and his economic adviser former Negros Occidental congressman Alfredo Abelardo Benitez, former Guimaras congressman JC Rahman Nava, and former Bacolod City congressman John Orola representing Mayor Evelio Leonardia of Bacolod City./PN * strengthen intra-regional market linkages and supply chains of local producers
GREENSBURG, Ind. – A former New Point volunteer firefighter was arrested after police say he took fire department equipment, charged gas to the department’s account and stole from residents.41-year-old Tracey S. Cook was booked into the Decatur County Jail and charged with two counts of burglary and five counts of theft. The charges are the result of three different cases and are all classified as felonies.Investigators were contacted in September by another New Point Volunteer firefighter who reported the department’s chainsaw was missing for approximately a year. The person also informed police that around 500 dollars of gasoline had been charged to the fire department without authorization.According to the Greensburg Daily News, police were told that Cook never returned a fire helmet and a radio after he “had been relieved of his duties.”The investigation led police to discovering the fire helmet at a Greensburg pawn shop and tickets showing a chainsaw matching the description of New Point Volunteer Fire Department’s had previously been sold, the newspaper reports.Cook allegedly attempted to pawn a radio but pawn shop staff did not accept it.While incarcerated on other charges in September, Cook reportedly told detectives that he did not receive permission to pawn items belonging to the fire department, but admitted to some gas charges. The newspaper reports that Cook allegedly denied some of the fuel charges saying he had permission.In a separate case, investigators allege Cook stole two grinders and a drill set from a residence in the 7300 block of East Base Road in Greensburg. Police believe he pawned those items off at the shop.Cook is facing burglary and theft allegations related to a case dating back to the spring. Police believe Cook stole a chainsaw and cordless drill from an unlocked garage. Cook allegedly admitted to taking the chainsaw and the drill that were reported missing.

Boss Nigel Pearson admits Leicester have been “trying to forget” their Manchester United heroics ever since they beat them 5-3. Leicester have failed to lift themselves off the bottom of the table after the run, despite winning two and drawing one of their last four league games. And Pearson, who guided the Foxes to a 2-1 FA Cup win at Tottenham last week, insists they must ignore the reminders of the past and focus on the present. He said: “We’ve been trying to forget about it ever since. It was great but until we beat Hull (in December) that was the last time we won. “I think the best thing for us to do is concentrate on what we are doing at the moment. “I don’t know if it has affected anything. It obviously has as the question has been asked. “I don’t spend much time looking at those angles. The game at our place was a very good result for us, we had a very good second half and scored at vital times. “But those are not the sort of events that happen every week.” Van Gaal admitted United looked unbalanced during their defeat at the King Power Stadium, where they played a diamond, and fans have called for him to shelve his preferred 3-5-2 formation and switch to 4-4-2. Pearson has sympathy for the Dutchman and insisted van Gaal’s United overhaul will take time. “I’ve never been in any doubt their manager will play the way he wants to,” he said. “But it may be a situation where he gets all his players in before the way he totally wants to play. That happens with everyone, it happened with us. “I would hope whoever we play have a healthy respect for us. But his track record as a manager is outstanding and he’s proved many times over the years he is capable of building sides. Over the initial building period there is rebuilding to do. “I can only speak from my own experience but you have to get enough results while you’re going through the building process to keep people on side or keep your job.” The Foxes face a rematch with United when they go to Old Trafford on Saturday. Their 5-3 win against Louis van Gaal’s side in September was their standout victory of the Barclays Premier League season – but it sparked a 13-game winless streak. Press Association
ISLAMABAD, Pakistan, (CMC) – Basit Ali said he still favours Pakistan to win their ongoing Test series against West Indies, although they suffered a huge setback following their defeat in Barbados.The former Pakistan batsman, now chairman of the Pakistan junior selection panel, said the 106-run defeat at Kensington Oval in the second Test which ended on Thursday was a wake-up call for the side and they will now have to rebound strongly for a historic victory.The Pakistanis came on the tour with the strong expectation of winning a Test series on Caribbean soil for the first time, but the Windies drew level 1-1 in the three-match rubber in Barbados after they lost the first Test by seven wickets at Sabina Park in Jamaica, making the third and final Test, starting on Wednesday at Windsor Park in Dominica, the decider.“I am sure, Misbah-ul-Haq and team management will learn from their mistakes and enter the series decider with a positive frame of mind,” said Basit.“Pakistan should enter the third Test with all guns blazing and win the series for the sake of Misbah to pay tribute to one of the highly successful captains Pakistan cricket has ever witnessed.”He added: “I seriously feel that the toss holds the key in determining the outcome of a Test match in the West Indies. The team, which wins the toss, I feel, it has bright chances of winning the Test matches.“It was [the] batsmen, who were at fault [in the second Test] and allowed the West Indian bowlers too much liberty and respect. Otherwise, Pakistan could have chased down the target, but the pitch also played a significant role and helped the West Indies bowlers a lot.”Basit also said critics should withhold their condemnation about the team selection, following the team management’s decision to introduce young leg-spinner Shadab Khan in Bridgetown.“I feel Shadab is extremely unlucky not to take at least four or more wickets, as the pitch was ideally supportive of his bowling,” said Basit. “Probably, he had put a lot of pressure on himself, otherwise, he was bound to succeed.“The bounce on West Indian pitches is uneven and it will take extra effort for the batsmen to spend time at the crease and spinners are bound to dominate, unlike the pitches of the 1990s, when the West Indian fast bowling greats use to rip apart the world’s best batsmen.”“Only those bowlers, who use seam to the best of their abilities, succeed in bagging wickets in the Caribbean, otherwise, only spinners can take huge advantage. I must give credit to Misbah for taking bold and wise decisions, even though his decision of including Shadab may have backfired.”
