Thieves looking for big scores with stolen truck tailgates BC police
ABBOTSFORD, B.C. – Truck owners in four Vancouver-area communities are being warned about thieves targeting vehicles for their pricey tailgates.Const. Ian MacDonald of the Abbotsford Police Department says over 80 tailgates have been stolen in the city since early 2016 as well as in Mission, Chilliwack and Langley.Charges have been laid against one man in connection to three thefts, and MacDonald says Abbotsford police are working with other jurisdictions to find more suspects.The bulky pieces of metal may seem difficult to steal, but MacDonald says the act of lowering a tailgate is unlikely to draw much suspicion from onlookers.He says once the gate is lowered, it’s relatively easy for someone to cut cables and lift the piece from a vehicle.MacDonald says thieves could sell the parts for up to $6,000 but replacing a tailgate can cost up to $10,000.“The ease and lucrative nature of it is really quite astonishing,” he says. “If every tailgate represents a $1,000 to $3,000 haul, it makes it a little bit more worthwhile to lug that very conspicuous item out of there.”Police say thieves seem to be targeting various truck models made between 2008 and 2016.Tailgates have gone missing in a variety of places, MacDonald says, including residential neighbourhoods and commercial areas where people have parked overnight.Truck owners are being urged to make sure their tailgates are locked to help prevent theft.
Barcelona’s Sergio Busquets feels that they only have themselves to blame after their unbeaten league run came to an end in their shocking 5-4 defeat to LevanteThe Catalan giants were 5-1 down against the 15th-place side at the Estadi Ciutat de València on Sunday night, before Phillipe Coutinho and Luis Suarez put the deficit down to 5-4 with 19 minutes remaining.However, Barcelona was unable to find an equaliser in the final moments and fell to their first La Liga defeat in 44 games.“Conceding five goals makes it very hard. We were caught on the counter-attack and there was a lack of concentration at times, too. Like I say, when you concede five, it’s hard to get anything positive from the game and that’s been the case,” said Busquets, according to Sport.The league champion’s late comeback proved to be futile in the end, despite their best efforts.“The fourth goal came with 20 minutes left,” he added.
Zidane reveals Sergio Ramos injury concern for Real Madrid Andrew Smyth – September 14, 2019 Zinedine Zidane has put Sergio Ramos’ availability for Real Madrid’s trip to Sevilla next weekend in doubt after withdrawing him against Levante.“We were pushing, working hard and used lots of energy, but that takes its toll in the end. We had chances to equalise but it wasn’t our night. When you give away five goals it’s hard to haul it back.”While disappointed to have not finished the season unbeaten, Busquets hopes that this defeat does not spoil what has been otherwise an outstanding season and the Spanish midfielder feels that his teammates should be proud to have managed a record 43 games unbeaten.“It’s clear we wanted to end the season unbeaten, but this doesn’t take any credit away from what we have done this season and everything we have achieved in La Liga,” said the 29-year-old.“The record [for games unbeaten, 43] we have over two years, but it’s shame [to lose out on an unbeaten season].“But we have won the league, it’s been an incredible season beyond this one game and I think we can be proud. Now we can celebrate with our fans in the final game.”
Wales have announced that Aaron Ramsey will miss their Uefa Nations League clash with the Republic of Ireland due to “family reasons”The loss of the Arsenal midfielder will come as another blow for head coach Ryan Giggs after Gareth Bale returned to Real Madrid.Wales were handed a 4-1 thrashing by Spain at Cardiff on Friday after a brace from forward Paco Alcacer, along with goals from defensive duo Sergio Ramos and Marc Bartra.Ramsey, whose Arsenal future remains increasingly uncertain, played the full 90 minutes of the loss but could not make an impact with Sam Vokes grabbing an 89th-minute consolation goal.Now the 27-year-old will be replaced by Swansea City’s Daniel James for Tuesday’s game in Dublin.

This is in addition to damage to schools which accounted for the majority of loss.As of today there remain a significant number of displaced departments which are currently being housed within other departments whilst they await repairs to government infrastructure. This includes critical departments such as the Information Technology, Customs, Planning, Land Registry, Public Works, Land Survey, Internal Audit and other departments on the island of Grand Turk. Following on from the Hurricanes the Ministry of Infrastructure conducted damage assessments and costing on all government buildings.In the area of communication, we have noted a marked improvement in communication services on the island of Grand Turk which should result in the full functionality of department phones. To this end persons can now once again reach departments through the switchboard numbers 946-2801 and 338-2801, while a full listing of government direct extensions is also posted on the governments website for easy reference. Kindly note that the departments telephone lines operate on a Voice Over Internet Protocol (VOIP) system which relies on the stability of the network itself.Revenue and Expenditure systems have suffered a number of challenges during recent months due to internet and communication instability, but with recent improvements by telecommunication providers this should shortly be resolved.We take the opportunity to thank our clients for their patience during this period and do hope that we can work to expeditiously resolve all remaining concerns.Please see below an updated listing of the affected departments new operating locations:Customs Department – Treasury Department, Front StreetCentral Information Technology Unit – Treasury Department, Front StreetPublic Works Department – Former Chief Minister’s Office, Government Compound, Pond StreetPlanning Department – Former Chief Minister’s Office, Government Compound, Pond StreetWater Undertaking Department – Former Chief Minister’s Office, Government Compound, Pond StreetLand Registry Department – Attorney General’s Chambers, Waterloo Plaza, Airport RoadValuation Department – Attorney General’s Chambers, Waterloo Plaza, Airport RoadSurvey and Mapping Department – Attorney General’s Chambers, Waterloo Plaza, Airport RoadCrown Land Unit – Attorney General’s Chambers, Waterloo Plaza, Airport RoadElections Department – Strategic Policy and Planning Unit, South BaseInternal Audit Department – Audit Department, Tony Clarke Office ComplexRoad Safety Department – Printing Department, Ruthann Lightbourne PlazaMinistry of Education, Youth and Sports – Franklyn Misick Building, Church FollyTCIG Press ReleasePhoto by Magnetic Media, Providenciales Police Headquarters after Hurricane Irma Editorial: Listen to your Mama TCI Premier Responds To Beaches’ Letter Announcing Closure Facebook Twitter Google+LinkedInPinterestWhatsApp Related Items:#hurricaneirmatci, #hurricanemariatci, TCIG Seriously, Sixth Form registration begins at Clement Howell High Aug 15

Indian pedestrians watch as a digital broadcast presents the rolling share price information and national election results news coverage on the facade of the Bombay Stock Exchange (BSE) building in Mumbai on May 16, 2014. India’s Hindu nationalist Bharatiya Janata Party (BJP) is on track to win the first parliamentary majority by a single party in 30 years, two television channels projected on May 16 based on preliminary results.PUNIT PARANJPE/AFP/Getty ImagesFollowing a steep decline in the Asian and other global markets, Sensex tanked 355 points on Monday over concerns of a global slowdown.Except for oil and gas and power sector stocks all the sectors on both BSE and NSE ended in the red led by finance and banking stocks.”Lingering concern on global economic slowdown dragged down the domestic indices. US bond yield has fallen as risk appetite of investors to equities reduced due to fear of US recession,” said Vinod Nair, Head of Research, Geojit Financial Services.The BSE Sensex declined 355.70 points or 0.93 per cent to 37,808.91, while Nifty shed 102.65 points or 0.90 per cent.Following the decline in the US equity markets last week, all eastern markets also slipped 1-2 per cent on Monday. European markets too were in the red, said Joseph Thomas of Emkay Wealth Management.”The lower manufacturing PMI in Germany, and contraction in Germany and France, and recession already having set in Italy, markets may progressively test lower levels.”The top gainers were ONGC which surged close to 4 per cent followed by Coal India, Power Grid, NTPC and Bajaj Finance up in the 1 to 2 per cent range.Among the losers were Vedanta, Tata Motors, Yes Bank, and Mahindra and Mahindra which declined up to 4 per cent.
US homeland security secretary Kirsten Nielsen (C) speaks during a press briefing on national security with Director of National Intelligence Dan Coats (L), FBI director Christopher Wray (2nd R) and Gen. Paul Nakasone (R), commander of the US Cyber Command (R) at the White House in Washington, DC, on 2 August. Photo: AFPThe US government on Thursday accused Russia of carrying out a “pervasive” campaign to influence public opinion and elections, in a warning just months before crucial legislative polls.“We continue to see a pervasive messaging campaign from Russia to try to weaken and divide the United States,” said Dan Coats, the director of national intelligence.A slew of top US officials including Coats, FBI director Christopher Wray and Homeland Security chief Kirstjen Nielsen vowed to investigate and prosecute those who were trying to sway US opinion or carrying out what Wray described as “information warfare.”“Our democracy itself is in the crosshairs,” Nielsen said in an unusually stark warning.“This is not just an election cycle threat,” Wray said. “Our adversaries are trying to undermine our country on a persistent and regular basis, whether it’s election season or not.”The comments came in jarring contrast to the positions of president Donald Trump, but the two men dismissed suggestions the president-who has repeatedly denied Russia moved to tilt the election in his favour-is not taking the issue seriously.In a letter to Congress, national security advisor John Bolton said the administration had taken “extensive, historic action” to stop the threat.Trump has mulled easing sanctions against Moscow, held warm meetings with Russian president Vladimir Putin and refused to criticize him over the meddling in the 2016 election.He has also repeatedly called for an end to the investigation into Moscow’s meddling, which has seen more than 20 Russians indicted so far.Asked whether the American people could trust the administration to do its job, Wray responded: “I can assure the American people that the men and the women of the FBI, from the director all the way on down, are going to follow our oaths and do our jobs.”
An Indian patient who drank toxic bootleg liquor is treated at Kushal Konwar Civil Hospital in Golaghat district in the northeastern Indian state of Assam on 23 February, 2019. Photo: AFPNinety-three workers have died and at least 200 others have been hospitalised in northeastern India after drinking toxic liquor, officials said Saturday, in the latest case of alcohol poisoning in the country.The deaths in Assam state came less than two weeks after tainted liquor killed about 100 people in the northern states of Uttar Pradesh and Uttarakhand.”The number of dead (in the district) has now increased to 58, and another 75 people are undergoing treatment” in local hospitals, Dhiren Hazarika, deputy commissioner of Golaghat district in Assam, told AFP.Another official from the neighbouring district of Jorhat said that 35 people had died there after consuming a batch of “spurious liquor”.Hazarika said people started falling sick after consuming a batch of illegally produced liquor late Thursday.The victims, who include many women, worked at local tea estates in the region. The death toll could rise further as both officials said some of the afflicted were in a critical condition.”The people came to the hospital with severe vomiting, extreme chest pain and breathlessness,” doctor Ratul Bordoloi, joint director of Golaghat’s health department, told AFP.Assam Chief Minister Sarbananda Sonowal has ordered an inquiry.State police said they had arrested one man for selling the liquor, and authorities said two excise department officials were suspended for failing to take adequate precautions over the sale of the alcohol.Assam health minister Himanta Biswa Sarma told AFP that state authorities had collated “at least 80” deaths in the districts. “But apart from this some more people died outside the hospital,” he added.”I also met the family members and relatives and ensured them that the perpetrators will not be spared,” Sarma said in a Twitter comment.Some media reports, citing anonymous sources, said that more than 100 people had died and the exact number was still being verified by authorities.Cheap, locally made liquor is common in parts of rural India and bootleggers often add methanol — a highly toxic form of alcohol sometimes used as an anti-freeze — to their product to increase its strength.If ingested in large quantities, methanol can cause blindness, liver damage and death.Hundreds of mainly poor people die each year in the South Asian country from tainted liquor, which normally costs just a few US cents a bottle.Of the estimated five billion litres of alcohol drunk every year in India, around 40 per cent is illegally produced, according to the International Spirits and Wine Association of India.Many Indian states have implemented or pushed for prohibition, which, according to critics, further increases the unsupervised manufacture and sale of alcohol.
Two Awami League leaders were shot dead by unidentified miscreants in Satkhira and Bandarban districts on Monday, reports UNB.In Satkhira, Nazrul Islam, 55, vice-president of Agardari union unit Awami League and son of Nesaruddin of Kuchpukur village in sadar upazila, was shot dead by miscreants at Kashempur Hazampara in the district town.Quoting witnesses, the superintendent of police of the district, Iltutmish, said a gang of miscreants appeared at the spot riding a motorbike and opened fire at Nazrul killing him on the spot while he was returning home from Kadamtala Bazar around 11:30am.The motive behind the killing could not be known yet.However, Palash, son of the victim, said his father might have been killed following an enmity with former UP member Towhidul.In Bandarban, Mong Pru Thoai, president of Tarasa union unit Awami League, was gunned down by miscreants at Shamukjhuri in Roangchhari upazila.The superintendent of police of Bandarban, Zakir Hossain, said the miscreants opened fire at Mong while he was going to the district town by a motorbike at noon. He died on the spot.Meanwhile, a joint force, including police and army, launched a manhunt to arrest the culprits.
Michael Marks/Texas StandardCattle stand in a Brazoria County pasture surrounded by Snow on the Mountain and other weeds.Up and down the Gulf Coast, Texans are still trying to get back to where they were before Hurricane Harvey. Some have had to rebuild from the ground up. For others, the trouble is with the ground itself.Fifty miles south of Houston in Brazoria County, Jessica Chase and Brady Stark are examining a piece of grass they found in Stark’s pasture.“This came in with Harvey. It’s a summer annual weed and it can reach up to three-and-a-half feet tall – yours are getting close,” Chase says.Chase is a Texas A&M Agrilife extension agent for Brazoria County. One of her jobs is to help landowners like Stark keep their pastures in good shape: identifying weeds like the Pennsylvania Smartweed she and Stark are looking at, and suggesting herbicides and fertilizers.And that’s important work in Brazoria County. It’s an exceptionally green place, where people raise cattle and horses, rice and sorghum. Stark’s been here since 1995. Over that time, he’s worked hard to keep his pastures in good shape for the cattle he raises. And they were in good shape until Hurricane Harvey.“After Harvey it was like, about a foot to maybe 16 inches deep. All over. I had water in the barns, but not in the house,” Stark says.His cattle were fine, but the pastures sat underwater for two weeks. They were caked in mud for another month after that. And once the mud washed off, the weeds came. Stark’s been able to get rid of a lot of them, but a ride around his property shows there’s still plenty left – with new species continuing to pop up. As we drive around to the backside of his pond, something catches Chase’s eye.“Did you have this thistle before Brady?” Chase asks.Chase is talking about a patch of plants that all have thin, spiny stems with equally prickly bulbs on top.“Now that you mention it I’ve seen several patches of this too,” Stark says.“I’ve seen several patches of it around. It is a thistle, I believe it’s blessed milk thistle. So that’s another one that’s been popping up also,” Chase says.Rains from Hurricane Harvey acted like a conveyer belt for weeds. As rivers, creeks and bayous breached their banks, they carried plant material with them. The water sitting over pastures like Stark’s became a soupy slurry of seeds.“Basically whatever your neighbors had that you worked so hard to keep off of your land – or the neighbor two miles up the road – is now on your property because that water just floated it all across,” Chase says. “So basically everything that everybody had in the county is mixed all over the place.”Repairing pastures is expensive and time-consuming. But if you’re trying to raise livestock, you’ve got to do it. Cattle and horses usually won’t eat weeds, and even if they did, they wouldn’t get nearly the nutritional value they would from eating grass. Some weeds, like Snow on the Mountain – a species that has thrived after Harvey – are even toxic to cattle.Now many pastures affected by the storm have recovered. But others are still in bad shape, maybe too far gone to be salvaged. As I was driving around Brazoria County, I stopped to take a closer look at a property just outside Angleton, the county seat. The place was surrounded by a barbed wire fence and had a cattle guard leading up to the driveway. There are no cows. And the reason for that is that weeds have completely and totally taken over the pastures. All the grassy area around the house, which I would estimate probably comprises 15 to 20 acres, it is entirely weeds.Some of them came up to my waist, others were over my head. It’s a fate that Kevin Reifel’s been trying to avoid on his own land. He drove me over to take a look at some property between the San Bernard and Brazos rivers. He keeps a few horses on it, and he and his brother *used to raise cattle there too.“This was our main pasture and we have sold all the cows off of it,” Reifel’s says.The plot that was once thick with healthy Bermuda grass is now empty except for scrubby, spiny stands of weeds in between patches of mud. Reifel’s brother’s house flooded during the storm. He’s building a new one – this time raised up on 12 foot beams. But they had to sell their cattle after Harvey because they couldn’t take on both rebuilding a house and a pasture. To get it back in order, they’ll have to start over: till up the field, spray herbicides for all the weeds, and then replant the grass. Reifel knows better than most how much that will cost. He owns the local feed and ranch supply store in the city of Brazoria, so he’s had a big part in getting people what they need to get back to normal.“Grass seed, grass seed, grass seed – that a lot. Insecticide, herbicides, and feed. So just about everything that I sell, they’ve been buying,” Reifel says.Harvey’s been a boon for Reifel’s business he wishes never happened. In his part of Texas, the struggle against weeds and loss of good grass could go on for years. Because even though you might kill a weed above ground, it could still be alive below the surface. So for people like Brady Stark, getting back to normal will take time…“But I’ll get back. Just don’t know when,” says Brady Stark. Share

(Phys.org) —A team of engineering and physics researchers with members from the U.S., the U.K. and the Republic of Muldova has found that covering a common type of plastic with a graphene coating can increase its conductivity by up to 600 times. In their paper published in the journal Nano Letters, the team describes their new technique and how the coated materials they’ve created might be used in real world applications. Researchers combine graphene and copper in hopes of shrinking electronics Plastics are not very good conductors of heat—they are generally in the 0.15–0.24 W/mK range—which is a good trait when it’s produced as flakes and used as a stuffing inside a winter coat, but not so good when used in electronics that generally need to convey heat away from a source. Engineers would like to use them in more applications however, due to their very low cost, light weight and durability. Conversely, graphene is an excellent conductor of heat (in the 2000–5000 W/mK range) along with its other unique properties, though notably a lot of that improvement is lost when applied to a substrate—it’s still much better than plastic though. In this new effort the researchers sought to improve heat conduction in a plastic by applying graphene to its surface.The type of plastic used, PET, is very common—it’s used to make soda bottles and a myriad of other products in a nearly limitless variety of shapes. Graphene for the experiment was grown in sheets just a few microns thick and then applied to a thin sheet of PET. The heat conductance (along the surface) of the resultant material was tested using a non-contact optothermal Raman technique where the researchers found the conductance had been increased by approximately 600 times.The researchers suggest the graphene coated PET could be used in thermal management applications or thermal lighting or even inside electronic devices to help move heat away from heat generating chips.The team next plans to work on creating models that have more detail and which are based on multiscale simulations that will shed light on which sorts of real-world applications the coated plastics might best be used in.

© 2014 Phys.org Journal information: arXiv More information: Thermal Conductivity of Graphene Laminate, Nano Lett., 2014, 14 (9), pp 5155–5161. DOI: 10.1021/nl501996v . On Arxiv: http://arxiv.org/ftp/arxiv/papers/1407/1407.1359.pdfAbstractWe have investigated thermal conductivity of graphene laminate films deposited on polyethylene terephthalate substrates. Two types of graphene laminate were studied, as deposited and compressed, in order to determine the physical parameters affecting the heat conduction the most. The measurements were performed using the optothermal Raman technique and a set of suspended samples with the graphene laminate thickness from 9 to 44 μm. The thermal conductivity of graphene laminate was found to be in the range from 40 to 90 W/mK at room temperature. It was found unexpectedly that the average size and the alignment of graphene flakes are more important parameters defining the heat conduction than the mass density of the graphene laminate. The thermal conductivity scales up linearly with the average graphene flake size in both uncompressed and compressed laminates. The compressed laminates have higher thermal conductivity for the same average flake size owing to better flake alignment. Coating plastic materials with thin graphene laminate films that have up to 600× higher thermal conductivity than plastics may have important practical implications.

Citation: ‘Egg-based electronics’ offer surprisingly good electrical performance (2017, September 28) retrieved 18 August 2019 from https://phys.org/news/2017-09-egg-based-electronics-surprisingly-good-electrical.html Journal information: Nanotechnology The researchers, led by Qunliang Song at Southwest University, China, have published a paper on using hydrogen-peroxide-modified egg albumen for resistive switching memory in a recent issue of Nanotechnology.”As a promising alternative to the conventional silicon-based nonvolatile memory, the egg albumen has more advantages than other materials,” Song told Phys.org. “The bio-organic material egg albumen may have potential applications in the imitation of biological memory behavior, artificial intelligence, and brain-like intelligence because of the good compatibility.”This is not the first time that egg albumen has been incorporated into electronic devices. Previously, the albumen from chicken and duck eggs has been used in transistors and other devices as the dielectric (insulating) layer. However, the new work marks the first time that egg albumen has been used to make resistive memories. These memories are being developed as a next-generation alternative to the silicon-based memories that dominate today’s electronics. Resistive memories, which operate based on changes in resistance rather than electric current, have potential advantages such as higher speeds, higher densities, and smaller sizes.One of the main components of resistive memories is a dielectric film—here, the egg albumen-based film—which is normally insulating but can be made conducting by applying a voltage. Switching between these states of high and low electrical resistance corresponds to switching between the memory’s “off” and “on” states, respectively.The researchers demonstrated that the resistance of egg albumen material can be made switchable by mixing it with a 10% hydrogen peroxide solution. Egg albumen contains more than 40 different proteins that are linked together by weak chemical bonds. Deep inside these proteins are large numbers of iron, sodium, and potassium ions. The hydrogen peroxide easily breaks the bonds holding the proteins together, which denatures the proteins and, critically, exposes the ions. These ions, which are positively charged, then act as traps that capture negatively charged electrons that are injected when a voltage is applied. When the trap levels are low (few or no electrons), the dielectric material behaves as an insulator and the memory is in the “off” state. When a negative voltage is applied, it causes the traps to fill with electrons, the material becomes conducting, and the memory switches to its “on” state. To reset the memory, a positive voltage is applied, releasing the electrons from the traps and returning the memory to its “off” state.”Ions such as Fe3+, Na+ and K+ are always connected with protein chains in the chicken egg albumen, and so cannot work efficiently when charges are injected,” Song said. “Treated with 10% hydrogen peroxide solution, the ions can be exposed outside of the protein chains and act as the traps to capture the injected charges. Thus the resistive switching memory properties of the hydrogen peroxide-modified egg albumen film was efficiently improved compared to those of pristine egg albumen.”Overall, the researchers demonstrated that the egg-albumen-based resistive memory compares favorably to other memories, exhibiting a high on/off resistance ratio, as well as good retention and switching endurance even after repeated bending. “Although great progress and breakthroughs have been made regarding the new material’s application and structure design, the mechanism of resistive switching memory is still not completely clear,” Song said. “We will continue our investigation of the mechanism of resistive switching memory. At the same time, flexible, wearable and water-dissolution resistive switching memory cells will be developed using organic-modified egg albumen in our following work.” Explore further This document is subject to copyright.

In a new study, researchers have shown that, when egg albumen is mixed with hydrogen peroxide, a series of chemical reactions occurs that transforms the biomaterial into an active film that can be used to make transparent, flexible resistive memory devices.

Ratan Acherjee mastered the wash technique of Abanindranth Tagore, while Manoj Dutta continued to paint folk motifs. Portraying the diversity of Bengal modernism, the exhibition also incorporates a sketch by Jogen Chowdhury, dreamy landscapes of Prokash Karmakar, Suhas Roy’s female protagonist, Bimal Kar’s city and mountain-scapes and a self-portrait by Partiosh Sen as a thinker. Whether it is Sajal Roy’s allegorical and cubist works, Rabin Dutta’s female portraits of surreal quality or Subrat Gangooly’s festive colours, each work stands on its own. Recent trends of the contemporary Bengal are represented here by large-scale sculptural works of Rajesh Sharma and Suvajit Samanta, a bronze by Animesh Mahata, minimal figuration of Debabrata Sarkar, including Shovin Bhattacharjee’s psychological image and Parbir Kumar Bera’s depiction of carnal love.Connected only by the geographical confines of Bengal, the artists and art works on display include not just some of the most important names of the region, but also work of individual stylistic importance.
