Digicel congratulates ICC U-19 World Cup championsPeople usually remember the extraordinary ones – the hard workers and inventors, the movers and shakers. But most of all, they remember the history-makers.Digicel congratulates the members of the West Indies Under-19 cricket team, who have now joined the ranks of the history-makers with their outstanding performance at the ICC Under-19 Cricket World Cup.For the past few weeks, the entire region has been focused on the team’s progress throughout the tournament, and its momentous performance has indeed been a source of inspiration and motivation for everyone.In our support for youth and sport development, we constantly repeat the mantra, ‘from grassroots to greatness’, to encourage our young athletes to aim for the highest in all their pursuits. We are sure that this achievement by the team will also serve as encouragement for Caribbean youth who aspire to cricket beyond national borders.On that note, we also extend the heartiest of commendations to our local players Michael Frew, Shahid Crooks and Odean Smith for their outstanding performance, while representing Jamaica. We are especially delighted to see the growth and development of Michael Frew, who was a member of the winning team in the Digicel/ISSA T20 Tournament last year.The success of the team has no doubt set the stage for the exciting 2016 Caribbean Premier League season, which is fast-approaching. This accomplishment has helped to create renewed passion and pride in the sport for Caribbean people and promises a bright future ahead for West Indies cricket.
No sooner had Sean Carroll published his essay in Nature1 that dark matter proves how insignificant we are, that Geoff Brumfiel tells us in Nature Science Update that researchers can’t find the stuff. The Cryogenic Dark Matter Search II is four times more sensitive than previous searches, but came up empty. Carroll had just reiterated the common statistic that “About 70% of our current Universe is dark energy and 25% is dark matter. This leaves all the stuff we have directly observed at a paltry 5% of the whole Universe.” We see the light; where is the dark?1Sean Carroll, “Insignificance,” Nature 429, 27 (06 May 2004); doi:10.1038/429027a.Cosmologists love dark matter rather than light because their deeds are evolutionary. And you thought the pillar of science was observation.(Visited 10 times, 1 visits today)FacebookTwitterPinterestSave分享0
We recently installed a Fog Harvesting system in the Alfred Nzo District Municipality at a place called Cabazana.The experience was mindblowing. Although at this stage fog occurances are low (seasonal), local residents who are to benefit from this and will for the first time be able to drink potable water when the fog starts rolling in (September – April).Congrats to the Mayor and his council for caring for the people even if it means using innovative methods.This country can only get better if all of us took as much care and cut out the RED TAPE and just made it happen.View full story Engineering News, Innovative ‘Fog Harvesting’ system installed in the Eastern Cape.Story submitted to SAinfo on 1 July 2008
India’s fielding has been a huge disappointment in the series.Those who follow Indian cricket must have been at a loss of words to describe the way the team has been playing in England. So epic has been the capitulation of the Indians, who were the number one Test team in the world for the best part of two years, that words like humiliation and whitewash seem incapable of summarising the tragedy.India suffered their third heaviest defeat in Tests on Saturday and by the time S. Sreesanth edged one to Kevin Pietersen, watching the team play had become a strain on the eyes, mind and heart.Once the dust settles on what is left of the current Indian team, answers will have to be sought as to what could have possibly gone wrong. There can’t be one single factor for such annihilation. But there are certainly a few which can be collectively held responsible.The Indians were simply not prepared for the series; players broke down at crucial junctures; M.S. Dhoni didn’t have the firstchoice team at his disposal; the Indians are playing too much cricket; England are simply too good and have put in their all to win the series? the list is quite long.Let’s look back at what happened this year. India had a full tour of South Africa, including three Tests and five one-dayers. After that came the World Cup. Being held in the subcontinent, India wanted to win it badly. The pressure and expectations were so high that the players admitted by the time the knockout stages came, they couldn’t eat properly and threw up regularly.advertisementEmotionally and physically, the Indians were drained by the time they tamed the Aussies, overpowered Pakistan and lorded over the Sri Lankans.Lifting the coveted trophy after 28 years at home should have meant a long break for the battered mind and body of the players. But six days after Dhoni deposited Nuwan Kulasekara over the mid-on boundary in Mumbai, the players were back to the field for the Indian Premier League, this time their corporate bosses holding the reins.So instead of cooling down after putting themselves through the ultimate grind, they threw themselves into the maniacal cauldron of T20 cricket. And before long the wheels started to wobble.Virender Sehwag and Gautam Gambhir injured their right shoulders. Sehwag chose to play as long as the Delhi Daredevils were mathematically in the tournament. The day they were out, Sehwag was ruled injured and he flew to Germany to treat his shoulder. Gambhir said he wasn’t informed about the full extent of his injury by the Knight Riders’ physios, and that probably aggravated his condition.When the IPL jamboree finally ended on May 28, the players decided to take a break. So putting aside national interests, they decided to give the West Indies series, which followed soon after the IPL, a miss. Some players opted out of the entire tour or part of it, citing injury, fatigue and various other reasons. Sachin Tendulkar did not tour the Caribbean, Dhoni didn’t play in the ODIs, Zaheer Khan rested his hamstring and ankle.How and why did the players agree to play in the IPL and not in the West Indies has very little to do with cricket. It is a nobrainer that money power silenced cricketing logic.Arriving in England with hardly any practice as a team – no Sehwag for the first two Tests; the fitness of pace spearhead Zaheer untested and just one practice game under their belt – it was a disaster waiting to happen. And it was a disaster unlike anything seen by this generation.10 steps to disaster1. Zaheer’s hamstring: India’s pace spearhead injured his hamstring on the first day of the first Test at Lord’s. India had pinned all its hopes on one man and it all went downhill from there.2. Sachin’s viral: Sachin Tendulkar was indisposed due to a viral infection with India needing to bat out almost four session to save the first Test.3. Gambhir’s elbow hit: Got hit on the elbow after Matt Prior swept one straight at him. Was in considerable pain and missed the second Test. Struggled while batting at Lord’s as his hand movement was restricted.4. Broad-Swann stand: India had reduced England to 124 for eight on the first day at Nottingham. But a counter-attacking partnership between Stuart Broad and Graeme Swann took England to 221 on a bowler’s wicket.5. Broad hat-trick: In Trent Bridge, India had another chance to shut England out of the game when they were well placed at 267 for four. But Broad picked up a hat-trick as India collapsed to 288 all out. A possible lead of 150 and more became just 67.advertisement6. Harbhajan’s stomach strain: Dhoni was again short of bowling options in the second innings at Trent Bridge as Harbhajan Singh developed a stomach strain. Yuvraj Singh and Suresh Raina took up the bowling responsibilities and England carted them around gleefully.7. Butterfingers: With a number of straightforward catches dropped so far, including Rahul Dravid dropping sitters at first slip and MS Dhoni struggling to collect deliveries, Indian fielding sunk to depths rarely seen in international cricket.8. Lack of killer instinct: India had a golden chance to finish off England on the first two days of the second Test and also restrict them at Lord’s when the hosts were 107 for six. But they let them off the hook and have been thrashed as a result.9. Sehwag’s king’s pair: All eyes were on Virender Sehwag, returning from a shoulder surgery. Whether or not he was match-fit wasn’t looked into and despite his failure in the warm-up against Northants, it was hoped he would come good on match day. The king’s pair at Edgbaston dashed India’s hopes.10. Birmingham shootout: With Sehwag failing and England batsmen scoring runs at will, the writing was on the wall by the second day itself. England scored a little less than 400 runs on Day Two and Team India was simply waiting for the last rites.

The outline of M33s neutral hydrogen disk is shown in black, with all of the discrete detected clouds overlaid. The figure was made by integrating the flux over the velocity range of each cloud, then filling in the lowest contour. The central velocity of each cloud was used so the colours are indicative of this velocity. Velocities shown are relative to M33. Credit: Keenan et al., 2016. This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. The detection was made by a team of astronomers led by Olivia C. Keenan of the Cardiff University, U.K. The researchers used a set of data provided by the Arecibo Galaxy Environment Survey (AGES) that utilizes the Arecibo Telescope in Puerto Rico. AGES is a neutral atomic hydrogen survey aimed at searching for galaxies in different areas of the local universe. The scientists have analyzed the data from AGES to look at the neutral hydrogen distribution around M33. Investigating this area, they were searching for any hydrogen clouds that could be starless dwarf satellites of the galaxy. Due to the proximity of M33 and the high quality of AGES data, the team could easily detect new clouds around this galaxy.”It wasn’t too difficult to detect clouds around M33. What was more difficult was working out whether the clouds were part of the disk of M33, near M33 but unattached, or whether they were, in fact, related to our Milky Way galaxy. This meant we had to study each cloud in a lot of detail to work out if it was associated with M33,” Keenan told Phys.org.The team managed to detect 11 new clouds. They also found out that many previously detected clouds are actually part of the low neutral hydrogen disk of M33. However, they were not able to identify any stars associated with these clouds.”We now know a lot about where the gas is around M33 and what it looks like. M33 has an extended neutral hydrogen gas disk which is larger than the optical galaxy as it extends further than the stars. This disk is warped and has lots of clumpy dense regions, which may hint towards a past close encounter with the Andromeda galaxy. M33 also has a population of gas clouds which don’t have any stars associated with them. This is interesting, as we don’t know how these clouds of gas got there, or why they don’t have stars,” Keenan said.According to the study, the largest cloud found by the researchers, designated AGESM33-31, is the most intriguing one. It has a diameter of nearly 60,000 light years and a neutral hydrogen mass of about 12 million solar masses. If the cloud is at the distance of M33, it is larger in size than the galaxy.”We have found a large ring-shaped cloud which appears to be about as big as M33 itself,” Keenan noted.The origin of AGESM33-31 is yet to be determined. One of the hypotheses proposed by the team is that this cloud is the further extension of the Magellanic Stream. The researchers also suppose that the cloud could be the remnants of a dark galaxy that has been disrupted. However, these explanations do not account for the hole observed in this ring-shaped feature.”We have investigated the possibility that this hole may have been formed by a supernova, but found it to be around an order of magnitude too large for this to be a satisfactory explanation. AGESM33-31 remains an interesting and intriguing object, we would need additional observations to allow us to make further comment on its nature,” the scientists wrote in a paper.Keenan concluded that although the Arecibo Telescope is excellent to look for gas around nearby galaxies, a more powerful observatory, like the Square Kilometer Array (SKA), would be needed to continue the search in more remote locations.”We hope that as telescopes improve we will be able to detect more gas around galaxies, and see gas around galaxies which are further away. When the Square Kilometer Array telescope is complete it will be great for this kind of work,” she said.SKA is an international project to built a network of radio telescopes in Australia and South Africa. These telescopes will be tens of times more sensitive and hundreds of times faster at mapping the sky than today’s best radio astronomy facilities. First observations are currently scheduled for 2020.

As part of the Arecibo Galaxy Environment Survey (AGES) we have observed the neutral hydrogen (HI) gas in and around the nearby Local Group galaxy M33 to a greater depth than previous observations. As part of this project we investigated the absence of optically detected dwarf galaxies in its neighbourhood, which is contrary to predictions of galaxy formation models. We observed 22 discrete clouds, 11 of which were previously undetected and none of which have optically detected counterparts. We find one particularly interesting hydrogen cloud, which has many similar characteristics to hydrogen distributed in the disk of a galaxy. This cloud, if it is at the distance of M33, has a HI mass of around 10^7 Msun and a diameter of 18 kpc, making it larger in size than M33 itself. Image: Our flocculent neighbour, the spiral galaxy M33 © 2016 Phys.org (Phys.org)—While peering into the nearby Triangulum Galaxy known as M33, astronomers have detected what appears to be a giant cloud of hydrogen around it. According to research published online on May 5 on the arXiv pre-print server, the cloud is extremely large, even bigger than the galaxy itself. The discovery could improve our knowledge about the distribution of gas in and around galaxies.
